Before introducing the technical solutions of this application, technical issues in related technologies will be introduced in detail.

With the continuous development of display technology, users have higher and higher requirements for electronic devices, so a variety of electronic devices have been developed and launched, such as folding electronic devices, slide-type electronic devices, roll-type electronic devices, and so on. Among them, foldable electronic devices are favored by more and more users because of their unique folding performance, which means they have a larger display area when unfolded and a smaller overall size when folded. Foldable electronic devices can be divided into inward folding and outward folding in terms of bending direction. Among them, inward folding means that the two ends of the flexible screen are closer to each other than the casing and are protected by the casing, so that the user cannot see the flexible screen in the folded state. Outward folding means that the two ends of the flexible screen are farther away from each other than the casing. Although the flexible screen cannot be protected by the casing, the user can still view the display in the folded state.

And for inward folding, the flexible screen can be divided into U-shaped and teardrop-shaped according to the folded cross-sectional shape. Among them, U-shaped (U-Fold), as the name suggests, refers to the name given by the cross-sectional shape of the folded flexible screen that resembles the letter U. Water-Drop Fold, as the name suggests, refers to the fact that the cross-sectional shape of the flexible screen after folding resembles the shape of a water drop. In other words, the distance between the two halves of the water-drop-shaped flexible screen is small at the top and large at the bottom.

Whether it is folded inward or outward, whether it is formed into a U shape or a teardrop shape, currently, in order to realize the folding function of a foldable electronic device, a folding device installed in the electronic device is usually used. The folding device relies on its supporting member to move relative to the base, and cooperates with other components to move according to a preset movement trajectory, thereby constraining the flexible member into a U-shape or a tear-drop shape in the folded state. However, the current folding device has a complex structure, large overall size, and takes up a lot of space, which is not conducive to miniaturization development. For example, the rotating parts in some folding devices can slide relative to the base, which will cause the dimensions of the folding device, as well as the housing components and electronic equipment using the folding device to change in the length direction, thus causing the folding device to collapse. The overall length will become larger and take up more space, thereby reducing the installation space for other components such as the motherboard or battery.

Based on this, in order to solve the above problems, the present application provides a folding device. Please refer to FIGS. 1-8 and 18-19 together.

They mainly realize the rotating function of the folding device 1 and are driven and limited by the rotation of the first rotating member 20 and the second rotating member 20'. The components connected with the first rotating member 20 and the second rotating member 20' make these components move according to the preset movement trajectory. Among them, one end of the first rotating member 20 is subsequently used to be fixed on other components such as the casing. The other end of the first rotating member 20 is rotatably connected to the base 10 , that is, the end of the first rotating member 20 close to the base 10 is rotatably connected to the base 10 . In other words, the base 10 is usually stationary and fixed on the decorative piece, so the first rotating member 20 can rotate relative to the base 10 . And one end of the second rotating member 20' is subsequently used to be fixed on other components, such as the housing. The other end of the second rotating member 20' is rotatably connected to the base 10, that is, the end of the second rotating member 20' close to the base 10 is rotatably connected to the base 10. In other words, the second rotating member 20' can rotate relative to the base 10. As for the specific matching structure of the first rotating member 20 and the second rotating member 20' and the base 10, this application will introduce it in detail later.

Alternatively, in one embodiment, the rotating member and the housing may be of an integrated structure or a split structure. When the rotating part and the casing are of an integrated structure, the rotating part and the casing are prepared through a single process. However, for ease of understanding, the rotating part and the casing are artificially named differently. When the rotating member and the housing have a split structure, the rotating member and the housing are prepared separately, and then the rotating member is fixed on the housing through various methods such as bonding, screw connection, snap connection, etc. This embodiment is only schematically described with the rotating member and the housing having a separate structure.

The first rotating member 20 and the second rotating member 20' are provided on opposite sides of the axis C0 of the base 10. Optionally, in one embodiment, the first rotating member 20 and the second rotating member 20' are arranged axially symmetrically with respect to the axis of the base 10 (shown as C0 in Figure 3). In other embodiments, the first rotating member 20 and the second rotating member 20' may also be arranged non-axially symmetrically with respect to the axis C0 of the base 10. For example, the first rotating member 20 and the second rotating member 20' may be arranged along the axis C0 of the base 10. The axes C0 are staggered. In other words, the projections of the first rotating member 20 and the second rotating member 20' along the axis C0 direction of the base 10 partially overlap. This can further reduce the length of the folding device 1 and reduce the overall size of the folding device 1 . This embodiment is only schematically illustrated by assuming that the first rotating member 20 and the second rotating member 20' are arranged non-axisymmetrically with respect to the axis C0 of the base 10.

This embodiment does not limit the shape, structure, material and other parameters of the first rotating member 20 and the second rotating member 20', as long as one end of the first rotating member 20 and the second rotating member 20' can be fixed on the housing. The other ends of the first rotating member 20 and the second rotating member 20' can be rotationally connected to the base 10.

The first support member 30 and the second support member 30' are mainly used in the folding device 1 to subsequently support the flexible member 80 and to control the shape of the flexible member 80 when folded. In other words, the first support member 30 and the second support member 30' can be restricted by the movement trajectories of other components to move, Finally, the required folding form is achieved, which then drives the support member to be bent to form the required shape. The first support member 30 has a support surface 310 for supporting the flexible member 80 . Alternatively, the flexible member 80 may directly abut against the supporting surface 310 , or there may be a gap between the flexible member 80 and the supporting surface 310 . One end of the first supporting member 30 is rotatably connected to the first rotating member 20 , that is, the end of the first supporting member 30 away from the base 10 is rotatably connected to the first rotating member 20 . In other words, the first supporting member 30 can rotate relative to the first rotating member 20 . The other end of the first support member 30 is slidably and rotationally connected to the base 10 , that is, the other end of the first support member 30 can slide and rotate relative to the base 10 .

The second supporting member 30' also has a supporting surface 310 for supporting the flexible member 80. Alternatively, the flexible member 80 may directly abut against the supporting surface 310 , or there may be a gap between the flexible member 80 and the supporting surface 310 . One end of the second supporting member 30' is rotatably connected to the second rotating member 20', that is, the end of the second supporting member 30' away from the base 10 is rotatably connected to the second rotating member 20'. In other words, the second supporting member 30' can rotate relative to the second rotating member 20'. The other end of the second support member 30' is slidably and rotationally connected to the base 10, that is, the other end of the second support member 30' can slide and rotate relative to the base 10.

It should be noted here that the rotation mentioned above can be understood as the two components can perform circular motion around the axis of rotation. Sliding can be understood as the parallel movement of two parts, with only changes in displacement and no changes in angle. The fact that the two parts can both slide and rotate means that the two parts have both displacement and angle changes. At this time, this sliding and rotation can also be called rolling.

The first supporting member 30 and the second supporting member 30' are provided on opposite sides of the axis C0 of the base 10. Optionally, in one embodiment, the first support member 30 and the second support member 30 ′ are arranged axially symmetrically about the axis C0 of the base 10 . In other embodiments, the first support member 30 and the second support member 30' are arranged non-axisymmetrically with respect to the axis C0 of the base 10. This embodiment is only schematically described by assuming that the first support member 30 and the second support member 30 ′ are arranged axially symmetrically about the axis C0 of the base 10 .

This embodiment does not limit the shape, structure, material and other parameters of the first support member 30 and the second support member 30', as long as the first support member 30 and the second support member 30' can support the flexible member 80, and It is sufficient to achieve the above-mentioned matching relationship with the first rotating member 20, the second rotating member 20' and the base 10.

The folding device 1 provided in this embodiment can form an integral mechanism with the base 10, the first rotating member 20, and the second rotating member 20'. In one embodiment, the integral mechanism is disposed on a side of the first support member 30 and the second support member 30' away from the support surface 310. In another embodiment, the folding device 1 includes two integral mechanisms, both of which are disposed on the side of the first support member 30 and the second support member 30' in the support mechanism away from the support surface 310, and along the The first support member 30 and the second support member 30' are spaced apart in the length direction. In other embodiments, the folding device 1 may also include three or more integral mechanisms. The first support member 30 and the second support member 30' of the three or more integral mechanisms are located in the support mechanism away from the support surface 310. one side, and are spaced apart along the length direction of the first support member 30 and the second support member 30'.

In addition to the above-mentioned components, the folding device 1 may also include a hovering mechanism 40. The hovering mechanism 40 is used to keep the folding device 1 stationary when it is in a state between the unfolded state and the folded state. The first rotating member 20 and the second rotating member 20' will not fall back, so that the folding device 1 can stop at a certain position during rotation. The hovering mechanism 40 includes a sliding member 41 and a first elastic member 42 . The sliding member 41 is disposed on the base 10 and is slidably connected to the base 10, that is, the sliding member 41 can slide relative to the base 10, and one end of the sliding member 41 is rotationally connected to the first rotating member 20 and the second rotating member 20', Opposite ends of the first elastic member 42 respectively resist the other end of the sliding member 41 and the base 10 .

It is worth noting that the resistance mentioned in this application means as long as it can be contacted. As for the specific resistance, it can be contact, fixed connection, adhesion, etc.

Based on the above connection relationship, when the folding device 1 is folded, the first rotating member 20 , the second rotating member 20 ′, the first supporting member 30 , and the second supporting member 30 ′ rotate relative to the base 10 , and the first supporting member 30 The second support member 30' also slides relative to the base 10, and the first support member 30 and the second support member 30' are folded with each other. When the folding device 1 is unfolded, the first rotating member 20, the second rotating member 20', the first The support member 30 and the second support member 30' rotate relative to the base 10, the first support member 30 and the second support member 30' also slide relative to the base 10, and the first support member 30 and the second support member 30' unfold each other. .

Moreover, when the first rotating member 20 and the second rotating member 20' rotate relative to the base 10, the first supporting member 30 and the second supporting member 30' slide relative to the base 10. When rotating, the sliding member 41 slides relative to the base 10 to compress the first elastic member 42, so that the sliding member 41, the first rotating member 20 and the second rotating member 20' resist each other. hold.

The movement process of the folding device 1 mentioned above has a variety of active and passive logical relationships. This application uses one specific movement process as an example. When the folding device 1 is folded, that is, when the first rotating member 20 and the second rotating member 20' rotate relative to the base 10 and approach each other, since the first supporting member 30 is connected to the first rotating member 20, and the second supporting member 30 'Connect the second rotating member 20'. Therefore, the rotation of the first rotating member 20 and the second rotating member 20' can drive the first supporting member 30 and the second supporting member 30' to rotate relative to the base 10. And because the first support member 30 and the second support member 30' are also slidingly connected to the base 10, the first support member 30 and the second support member 30' will also slide relative to the base 10, and finally the first support member 30 Fold with the second support member 30'. In addition, when the first rotating member 20 and the second rotating member 20' rotate, the sliding member 41 slides relative to the base 10 and the first elastic member 42 is compressed. The elastic force of the first elastic member 42 can make the sliding member 41 more closely resist the first rotating member 20 and the second rotating member 20', thereby improving the friction between the sliding member 41 and the first rotating member 20 and the second rotating member 20'. Friction. Furthermore, when the first rotating member 20 and the second rotating member 20' stop rotating, the first rotating member 20 and the second rotating member 20' are in a stationary state relative to the base 10, thus achieving a hovering effect.

Similarly, when the folding device 1 is unfolded, that is, when the first rotating member 20 and the second rotating member 20' rotate in opposite directions relative to the base 10 and move away from each other, since the first supporting member 30 is connected to the first rotating member 20, and the second The support member 30' is connected to the second rotating member 20'. Therefore, the first rotating member 20 and the second The rotation of the rotating member 20' can drive the first supporting member 30 and the second supporting member 30' to rotate in opposite directions relative to the base 10. And because the first support member 30 and the second support member 30' are also slidingly connected to the base 10, the first support member 30 and the second support member 30' will also slide relative to the base 10, and finally the first support member 30 and the second support member 30' are unfolded from each other. In addition, when the first rotating member 20 and the second rotating member 20' rotate in opposite directions, the rebound force of the first elastic member 42 can cause the sliding member 41 to slide in the opposite direction relative to the base 10, and can also cause the sliding member 41 to slide relative to the base 10. The base 10 slides and compresses the first elastic member 42 . The elastic force of the first elastic member 42 can make the sliding member 41 more closely resist the first rotating member 20 and the second rotating member 20', thereby improving the friction between the sliding member 41 and the first rotating member 20 and the second rotating member 20'. Friction. Furthermore, when the first rotating member 20 and the second rotating member 20' stop rotating, the first rotating member 20 and the second rotating member 20' are in a stationary state relative to the base 10, thus achieving a hovering effect.

Of course, in other embodiments, the active and passive relationships of the above-mentioned components can be reversed. For example, the first support member 30 and the second support member 30' may rotate relative to the base 10 to drive the first rotating member 20 and the second rotating member. 20' rotates relative to the base 10. Such movement processes and principles should also fall within the protection scope of this application.

When the first support member 30 and the second support member 30' are parallel to each other, and the first support member 30 and the second support member 30' are located on opposite sides of the base 10, it can also be understood that the first support member 30 is close to the base. When the side 732 of the seat 10 is moved, the first support member 30 and the second support member 30' are in a fully unfolded state with each other. In other words, the folding device 1 is in an unfolded state, as shown in Figures 1-4. When the first support member 30 and the second support member 30' are parallel to each other, and the first support member 30 and the second support member 30' are both located on one side of the base 10, it can also be understood that the first support member 30 and the second support member 30' are parallel to each other. When the two support members 30' are both located on the top surface 100 of the base 10, the first support member 30 and the second support member 30' are in a completely folded state with each other. In other words, the folding device 1 is in a folded state, as shown in Figure 6 -As shown in Figure 8. When the first support member 30 and the second support member 30' are folded with each other, that is, the process of the folding device 1 from the unfolded state to the folded state can also be understood as the process from Figure 4 to Figure 8, at this time the first rotating member 20 The first support member 30 and the second support member 30' are mutually rotated and brought closer to each other to drive the first support member 30 and the second support member 30' to merge with each other to achieve mutual closeness and folding. When the first support member 30 and the second support member 30' unfold each other, that is, the process of the folding device 1 from the folded state to the unfolded state, which can also be understood as the process from Figure 8 to Figure 4, at this time the first rotating member 20 The first support member 30 and the second support member 30' are separated from each other by rotating and moving away from each other with the second rotating member 20', so as to achieve mutual separation and expansion.

When the folding device 1 is in the folded state, the first support member 30 and the second support member 30' and the base 10 can jointly form a receiving space 11 for receiving the flexible member 80. The folding device 1 provided in this embodiment can The cross-sectional shape of the flexible member 80 is U-shaped or teardrop-shaped. This embodiment is only schematically described by assuming that the cross-sectional shape of the accommodation space 11 is a teardrop shape.

To sum up, the folding device 1 provided in this embodiment can be folded only through the mutual cooperation of five components: the base 10, the first rotating member 20, the second rotating member 20', the first supporting member 30 and the second supporting member 30'. The first support member 30 and the second support member 30' can be folded and unfolded with each other, that is, the folding and unfolding functions of the folding device 1 can be realized. Moreover, this embodiment can also realize the hovering function through the cooperation of the base 10, the first rotating member 20, the second rotating member 20', the sliding member 41, and the first elastic member 42. Therefore, in this embodiment, the first rotating member 20 and the second rotating member 20' can be used to realize both folding and unfolding and hovering, so that the folding device 1 has fewer components, a simple and compact structure, and saves more space. Compared with related technologies, the size of the folding device 1 is reduced and the internal space of the housing assembly 2 and the electronic device 3 is occupied, which is conducive to the development of miniaturization of the folding device 1 . It is also conducive to the layout of other components such as the motherboard or battery, thereby improving the battery life and heat dissipation function of the electronic device 3.

Optionally, when the folding device 1 is in the unfolded state, the supporting surface 310 of the first supporting member 30 and the supporting surface 310 of the second supporting member 30' can be coplanar with the top surface 100 of the base 10, so that the flexible member 80 can It is in contact with the supporting surface 310 of the first supporting member 30 and the top surface 100 of the base 10 . Of course, in other embodiments, the support mechanism may also include a third support member 60 (not shown in the figure) disposed between the first support member 30 and the second support member 30'. The third support member 60 is installed on the base. On one side of the top surface 100 of the seat 10 , the third support member 60 also has a support surface 310 for supporting the flexible member 80 . When the folding device 1 is in the unfolded state, the supporting surface 310 of the first supporting member 30 , the supporting surface 310 of the second supporting member 30 ′ and the supporting surface 310 of the third supporting member 60 are coplanar, so that the flexible member 80 can abut at the same time. On the supporting surface 310 of the first supporting member 30 , the supporting surface 310 of the second supporting member 30 ′ and the supporting surface 310 of the third supporting member 60 . The relevant content of the third support member 60 will be introduced in detail later in this application.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood on a case-by-case basis. For example, various connections in this embodiment include direct connections and indirect connections. For example, the connection of two components includes the direct connection of two components or the connection through a third component or more other components. Connection also includes two situations: integrated connection and non-integrated connection. Integrated connection means that the two components are formed and connected in one piece, and non-integrated connection means that A and B are formed and connected in a non-integrated manner.

Please refer to Figure 8 again. In this embodiment, the first supporting member 30 also rotates relative to the first rotating member 20, and the second supporting member 30' also rotates relative to the second rotating member 20', so that when the folding device 1 is in the folded state The first support member 30 and the second support member 30' are located on the same side of the base 10. side, and the distance between the first support member 30 and the second support member 30' at the end away from the base 10 is less than or equal to the distance between the first support member 30 and the second support member 30' at the end close to the base 10 .

When the folding device 1 is in motion, in addition to rotating and sliding relative to the base 10 , the first supporting member 30 and the second supporting member 30 ′ can also rotate relative to the first rotating member 20 , and the second supporting member 30 ′ can also rotate relative to the first rotating member 20 . 30' can also rotate relative to the second rotating member 20'. Specifically, the ends of the first support member 30 and the second support member 30' close to the base 10 can be rotated in a direction close to the first rotating member 20 and the second rotating member 20', so that when the folding device 1 is in the folded state The distance between the first support member 30 and the second support member 30' at the end away from the base 10 is smaller than the distance between the first support member 30 and the second support member 30' at the end closer to the base 10, that is, the first support A gap that is small at the top and large at the bottom is formed between the member 30 and the second supporting member 30'. In other words, the receiving space 11 formed by the first supporting member 30 , the second supporting member 30 ′ and the base 10 is in the shape of a water drop with a small top and a large bottom, that is, a water drop-shaped receiving space 11 , thereby making the flexible member 80 The cross-sectional shape is drop-shaped, thereby reducing the thickness of the folding device 1 after folding. As for how to specifically design the structure of the folding device 1 to limit the movement trajectories of the first support member 30 and the second support member 30' and ultimately achieve a water drop-shaped cross-sectional shape of the receiving space 11, this application will introduce it in detail below.

In other embodiments, the first supporting member 30 and the second supporting member 30' may not rotate relative to the first rotating member 20 and the second rotating member 20', or the first supporting member 30 and the second supporting member 30' may be opposite to each other. When the first rotating member 20 and the second rotating member 20' rotate, the angle between the first supporting member 30 and the first rotating member 20 after rotation, and the angle between the second supporting member 30' and the second rotating member 20' The angle between them does not change. At this time, when the folding device 1 is in the folded state, the first support member 30 and the second support member 30' and the base 10 can surround a U-shaped receiving space 11. In other words, when the first support member 30 and the second support member 30' are in the folded state, the first support member 30 and the second support member 30' are both located on the same side of the base 10, and the first support member 30 and the second support member 30' are in the folded state. The distance between the end of the support member 30' far away from the base 10 is equal to the distance between the end of the first support member 30 and the second support member 30' close to the base 1010, that is, the first support member 30 and the second support member 30 ' to form a gap of equal width up and down.

Please refer to FIG. 5 and FIG. 9 to FIG. 11 together. FIG. 9 is a schematic diagram of the cooperation between the first support member and the base in an embodiment of the present application. FIG. 10 is a schematic view of the cooperation between the first support member and the base shown in FIG. 9 from another perspective. FIG. 11 is an exploded schematic view of the first support member and the base shown in FIG. 9 . In this embodiment, the first support member 30 includes a connected support portion 31 and a rolling portion 32 , and the rolling portion 32 is slidably and rotationally connected to the base 10 . The rolling part 32 and the base 10 are connected through a first rolling shaft 320 and a first rolling groove 321. The first rolling shaft 320 is provided on one of the rolling part 32 and the base 10. The first rolling groove 321 is provided on the rolling part. 32 and the other of the base 10.

The supporting part 31 in the first supporting part 30 is used to support the flexible part 80 , so the supporting part 31 has a supporting surface 310 for supporting the flexible part 80 . The rolling part 32 is provided on the side of the supporting part 31 away from the supporting surface 310 , and the rolling part 32 is closer to the first rotating member 20 than the supporting part 31 . The support part 31 and the rolling part 32 may have an integrated structure or a separate structure. When the supporting part 31 and the rolling part 32 are of an integrated structure, the supporting part 31 and the rolling part 32 are prepared through a single process. However, for ease of understanding, the supporting part 31 and the rolling part 32 are artificially named differently. When the supporting part 31 and the rolling part 32 have a split structure, the supporting part 31 and the rolling part 32 are prepared separately and then connected together through various methods. This embodiment is only schematically described with the support part 31 and the rolling part 32 having a separate structure.

Therefore, the above-mentioned first support member 30 slides and rotates to connect to the base 10 , that is, the rolling part 32 slides and rotates to connect to the base 10 . Specifically, the rolling part 32 and the base 10 are connected through a first rolling shaft 320 and a first rolling groove 321. The first rolling shaft 320 is provided at one of the rolling part 32 and the base 10. The first rolling groove 321 is provided at on the other one of the rolling part 32 and the base 10 . For example, when the first rolling shaft 320 is provided on the rolling part 32, the first rolling groove 321 is provided on the base 10. When the first rolling shaft 320 is provided on the base 10 , the first rolling groove 321 is provided on the rolling part 32 . This embodiment is only schematically described by assuming that the first rolling shaft 320 is provided on the base 10 and the first rolling groove 321 is provided on the rolling part 32 . The first rolling shaft 320 can rotate relative to the first rolling groove 321 to rotate the first support member 30 relative to the base 10 . At the same time, the first rolling shaft 320 can also slide in the first rolling groove 321 to rotate the first supporting member 30 relative to the base 10 . The member 30 slides relative to the base 10 so that the first supporting member 30 slides and rotates relative to the base 10 . Optionally, the first rolling axis 320 includes but is not limited to a pin.

Optionally, the first rolling shaft 320 and the rolling part 32 or the base 10 may be fixedly connected or rotationally connected. For example, in this embodiment, the first rolling shaft 320 is provided on the base 10. The first rolling shaft 320 can be fixed on the base 10 so that the first rolling shaft 320 and the base 10 remain relatively stationary, thereby making the first rolling groove 321 slides and rotates relative to the first rolling shaft 320 . Alternatively, the first rolling shaft 320 can also be rotatably connected to the base 10 so that the first rolling shaft 320 and the base 10 maintain relative rotation, so that the first rolling groove 321 can still slide and rotate relative to the first rolling shaft 320 . Further optionally, when the first rolling shaft 320 is fixed on the base 10, the first rolling shaft 320 and the base 10 may be of an integrated structure or may be of a split structure. Specifically, in this embodiment, the first rolling shaft 320 can be installed on the base 10 by inserting the shaft.

Optionally, the base 10 is provided with a first rotation space 12. The first rotation space 12 is used to accommodate the rolling portion 32 of the first support member 30 and the rolling portion 32 of the second support member 30', for the rotation of the rolling portion 32. A space is reserved for sliding to prevent the rolling part 32 from interfering with the base 10 .

It is worth noting that this embodiment and the following description only use half of the structure of the folding device 1 for schematic description. In other words, only the structure of the right half of the folding device 1 is used for schematic description. For example, this embodiment only uses the structure of the right half of the folding device 1. The first rotating member 20 and the first supporting member 30 on the right side of the base 10 are schematically illustrated. As for the second rotating member 20' and the second supporting member 30' located on the left side of the base 10, they can be understood in the same way as the first rotating member 20 and the first supporting member 30 of this embodiment, and will not be described again in this embodiment. .

Please refer to Figures 4 and 8 again. In this embodiment, the support portion 31 has a support surface 310, and the first rolling groove 321 has a first limiting end 3211 and a second limiting end 3212 arranged oppositely. The first limiting end 3211 is closer to the supporting surface 310 than the second limiting end 3212, and when the folding device 1 is in the folded state, the first limiting end 3211 is further away from the base 10 than the second limiting end 3212. Among them, when folding device 1 When in the unfolded state, the first rolling shaft 320 is positioned at the first limiting end 3211. When the folding device 1 is in the folded state, the first rolling shaft 320 is positioned at the second limiting end 3212.

The first rolling groove 321 has two opposite ends: a first limiting end 3211 and a second limiting end 3212. Since the first rolling shaft 320 slides in the first rolling groove 321, the first limiting end 3211 can be used to slide the first rolling groove 321. The side walls of the position end 3211 and the second limit end 3212 limit the sliding of the first rolling shaft 320, so that the sliding of the first rolling shaft 320 ends when it slides to the first limit end 3211 and the second limit end 3212. Can't slide any further. As shown in FIG. 8 , the first limiting end 3211 is closer to the supporting surface 310 than the second limiting end 3212 , that is, the first limiting end 3211 is higher than the second limiting end 3212 . At the same time, when the folding device 1 is in the folded state, the first limiting end 3211 is further away from the base 10 than the second limiting end 3212, that is, the first limiting end 3211 is further to the right than the second limiting end 3212. Therefore, the first limiting end 3211 is located at the upper right position, and the second limiting end 3212 is located at the lower left position.

During the movement of the folding device 1, when the folding device 1 is in the unfolded state, the first rolling shaft 320 is positioned at the first limiting end 3211 to prevent the first support member 30 from being folded back and damaging the subsequent flexible member 80. When the folding device 1 is in the folded state, the first rolling shaft 320 is positioned at the second limiting end 3212 to prevent the first support member 30 from further bending and thereby damaging the subsequent flexible member 80 . In other words, the first rolling axis 320 is located on the upper right when the folding device 1 is in the unfolded state, and the first rolling axis 320 is located on the lower left when the folding device 1 is in the folded state.

Therefore, during the process of the folding device 1 from the unfolded state to the folded state, the first rotating member 20 rotates relative to the base 10. At this time, the first rotating member 20 drives the first supporting member 30 to rotate and slide relative to the base 10, thereby causing the second supporting member 30 to rotate and slide relative to the base 10. Once the position of the rolling shaft 320 changes, it can move from the first limiting end 3211 to the second limiting end 3212, or in other words, the first rolling shaft 320 moves from the upper right to the lower left direction in the first rolling groove 321, so that The first support member 30 and the second support member 30' cooperate with the base 10 to surround the water drop-shaped receiving space 11.

Please refer to Figure 12, which is a front view of the first support member in an embodiment of the present application. In this embodiment, the first rolling groove 321 also has a first communication portion 3213 that communicates with the first limiting end 3211 and the second limiting end 3212 . The first communication portion 3213 protrudes in a direction away from the supporting surface 310 .

The first rolling groove 321 is a chute 414 with a certain length. Therefore, in addition to the first limiting end 3211 and the second limiting end 3212, the first rolling groove 321 also has a connecting first limiting end 3211 and a second limiting end. The first communication portion 3213 of the end 3212 and the first rolling shaft 320 are located in the first communication portion 3213 in other states except the unfolded state and the folded state. This embodiment can make the first communication portion 3213 move away from the support surface 310 It can also be understood that the shape of the first connecting portion 3213 is an arc, and the arc is convex in a direction away from the supporting surface 310 , so that the first rolling shaft 320 can move during the entire movement of the first rolling shaft 320 . The support member 30 rotates with the first rotating member 20 to form a water drop shape. In addition, the movement of the first rolling shaft 320 can be made smoother, thereby improving the smoothness and stability of the movement of the folding device 1 .

Of course, in other embodiments, the shape of the first communication portion 3213 may also be linear or other shapes, as long as the positions of the first limiting end 3211 and the second limiting end 3212 are ensured to meet the above position limitations.

Please refer to FIG. 12 again. In this embodiment, the first rolling groove 321 also has a second communication part 3214 that connects the first communication part 3213 and the first limiting end 3211. The extending direction of the second communication part 3214 is parallel to the support surface 310. .

In addition to the first limiting end 3211, the second limiting end 3212, and the first communication part 3213, the first rolling groove 321 may also include a second communication part 3214 connecting the first communication part 3213 and the first limiting end 3211. , that is, there is a second communication part 3214 between the first communication part 3213 and the first limiting end 3211 . In other words, during the process of the folding device 1 from the unfolded state to the folded state, the first rolling shaft 320 does not move directly from the first limiting end 3211 to the first communication part 3213, but is first located at the second communication part 3214, and then before moving to the first communication part 3213.

In this embodiment, the extension direction of the second communication portion 3214 can be parallel to the support surface 310 , that is, the extension direction of the second communication portion 3214 is horizontal. In this way, the horizontal second communication portion 3214 can be used when the folding device 1 is in the unfolded state. To support the first rolling shaft 320, prevent the first rolling shaft 320 from moving from the first limiting end 3211 to the arc-shaped first connecting portion 3213, thereby improving the stability of the folding device 1. In addition, the horizontal second connecting portion 3214 can also reduce the gap between the first rolling shaft 320 and the first rolling groove 321 to prevent the existence of empty positions.

Please refer to FIG. 4 again. In this embodiment, the base 10 has a bottom surface 101 away from the first support member 30 and the second support member 30'. The first rotation axis between the first support member 30 and the base 10 is C1 is closer to the bottom surface 101 than the second rotation axis C2 between the first rotating member 20 and the base 10 , and the first rotation axis C1 is further away from the base than the second rotation axis C2 10 (ie, the axis C0 of the base 10 mentioned above).

From the above, it can be seen that the first supporting member 30 and the first rotating member 20 are both rotationally connected to the base 10. Therefore, there is a first rotating axis C1 between the first supporting member 30 and the base 10. The first rotating member 20 and the base 10 are connected to each other. There is a second rotation axis C2 between the seats 10. This embodiment can make the first rotation axis C1 closer to the bottom surface 101 than the second rotation axis C2, that is, the first rotation axis C1 is closer to the bottom surface 101 than the second rotation axis C2. Lower than the second rotation axis line C2. At the same time, the first rotation axis C1 is further away from the central axis C0 of the base 10 than the second rotation axis C2, that is, the first rotation axis C1 is further to the right than the second rotation axis C2. Therefore, the first rotation axis C1 is located at the lower right, and the second rotation axis C2 is located at the upper left. Such control of the positions of the first rotation axis C1 and the second rotation axis C2 can further control the movement trajectory of the first support member 30 , thereby forming a water drop-shaped receiving space 11 in the folded state. In other words, the present application can control the movement trajectory of the first support member 30 through the cooperation of the positions of the first rotation axis C1 and the second rotation axis C2, as well as the shape of the first rolling groove 321, and ultimately form a water drop shape. Containment Space 11.

Please refer to FIG. 5 and FIG. 16-FIG. 17 together. FIG. 16 is a schematic diagram of the cooperation between the first rotating member and the base in an embodiment of the present application. FIG. 17 is an exploded schematic view of the first rotating member and the base shown in FIG. 16 . In this embodiment, the first rotating part 20 includes a fixed part 21 and a second rotating part 22 fixed on the side of the fixed part 21 close to the base 10. One side of the second rotating part 22 and the base 10 pass through the second rotating part 22. The arc rail 220 is cooperatively connected with the second arc groove 221. The second arc rail 220 is provided on one of the second rotating part 22 and the base 10. The second arc groove 221 is provided on the second rotating part 22 and the base 10. the other in the base 10.

The fixing part 21 is used to subsequently connect the first rotating part 20 with other components.

The second arc rail 220 is provided between the second rotating part 22 and the base 10. On the one hand, the second arc groove 221 is provided on the other of the second rotating part 22 and the base 10 . For example, when the second arc rail 220 is provided on the second rotating part 22 , the second arc groove 221 is provided on the base 10 .

This embodiment is only schematically described with the second arcuate rail 220 being disposed on the base 10 and the second arcuate groove 221 being disposed on the second rotating part 22 .

Specifically, the base 10 has a second rotation space 13, and at least part of the second rotation part 22 is disposed in the second rotation space 13 to reserve a rotation space for the second rotation part 22 to prevent the second rotation part 22 from interfering with the base. 10 interference.

In addition, the design method of arc grooves and arc rails can make the position of the second rotation axis C2 either inside the base 10 or outside the base 10 . For example, when the position of the second rotation axis C2 is located outside the base 10, it is easier to make the first rotation axis The center line C1 is closer to the bottom surface 101 than the second rotation axis center line C2. The first rotation axis center line C1 is further away from the central axis C0 of the base 10 than the second rotation axis center line C2.

Please refer to Figures 5 and 18-19 again. In this embodiment, the base 10 has a sliding space 14, at least part of the hovering mechanism 40 is located in the sliding space 14, and the sliding member 41 abuts the second rotating part. On the other side of 22 , the opposite ends of the first elastic member 42 are respectively in contact with the sliding member 41 and the groove wall of the sliding space 14 . When the folding device 1 is folded, the first rotating member 20 rotates relative to the base 10, and the sliding member 41 slides relative to the base 10 and slides in the direction of the groove wall close to the sliding space 14 to compress the first elastic member 42. When the first When the rotating member 20 stops rotating, the first rotating member 20 is in a stationary state relative to the base 10 .

The hovering mechanism 40 can be located in the sliding space 14, that is, the sliding member 41 and the elastic member can be located in the sliding space 14, so that the structure of the folding device 1 is more compact, the components are highly integrated, and the size of the folding device 1 is further reduced. It can be seen from the above that the second rotating part 22 of the first rotating member 20 is disposed in the second rotating space 13 , and one side of the second rotating part 22 is connected to the base 10 for rotation. Therefore, the second rotating space 13 can be connected to the sliding space 14, and the other side of the second rotating part 22 can contact the sliding member 41, and the opposite ends of the first elastic member 42 are respectively in contact with the second rotating part 22 and the sliding member 41. The tank wall of space 14.

When the folding device 1 is folded, the second rotating part 22 of the first rotating part 20 rotates relative to the base 10 (the direction of the first rotating part 20 is shown as D1 in Figure 18 ), that is, the second rotating part 22 rotates relative to the sliding part 41 At this time, since the second rotating part 22 contacts the sliding member 41, the rotation of the second rotating part 22 can cause the sliding member 41 to slide relative to the base 10 and in a direction away from the first rotating member 20 (D2 in Figure 18 shown) slide. In other words, the sliding member 41 slides along the groove wall close to the sliding space 14 . And because the sliding member 41 abuts the first elastic member 42, the sliding of the sliding member 41 can compress the first elastic member 42. The compressed first elastic member 42 will give the sliding member 41 elastic force, causing the sliding member 41 to press the second rotating part 22 . At this time, when the first rotating member 20 stops rotating, the pressure between the sliding member 41 and the second rotating part 22 can be converted into the friction force between the sliding member 41 and the second rotating part 22, and the first rotating member 20 can pass the friction. The force thus causes the first rotating member 20 to be in a stationary state relative to the base 10, thereby realizing the hovering function.

For example, when the folding device 1 is in the unfolded state, the angle of the first rotating member 20 relative to the base 10 is 0°, and when the folding device 1 is in the unfolded state, the angle of the first rotating member 20 relative to the base 10 is 90°. When the folding device 1 moves from the unfolded state to the folded state, when the first rotating member 20 rotates 30° relative to the base 10, a large friction force is generated between the second rotating part 22 and the moving part, so that when When the first rotating member 20 stops rotating, it remains in a stationary state and will not fall back, achieving the purpose of free hovering.

It is worth noting that the contact mentioned above and below means as long as it can be contacted. As for the specific contact, it can be abutting contact, fixed connection contact, adhesive contact, etc.

In addition, the sliding member 41 can also contact the second rotating part 22 of the second rotating member 20', and the opposite ends of the first elastic member 42 are respectively in contact with the second rotating part 22 of the second rotating member 20' and the sliding space 14. The tank wall. The hovering principle of the second rotating member 20', the sliding member 41, and the first elastic member 42 is the same as that of the first rotating member 20, the sliding member 41, and the first elastic member 42. This embodiment does not Again.

Please refer to FIGS. 20 to 24 together. FIG. 20 is a schematic diagram of the cooperation between the first rotating member and the sliding member in an embodiment of the present application. FIG. 21 is an exploded schematic view of the first rotating member and sliding member shown in FIG. 20 . FIG. 22 is an exploded schematic view of the first rotating member and the sliding member shown in FIG. 20 from another perspective. FIG. 23 is a schematic diagram of the cooperation between the first rotating member and the sliding member when the folding device is in an unfolded state according to an embodiment of the present application. Figure 24 is a schematic diagram of the cooperation between the first rotating member and the sliding member when the folding device is in a folded state according to an embodiment of the present application. In this embodiment, a first cam part 411 is provided on the other side of the second rotating part 22. The first cam part 411 has a first wave peak 4111 and a first wave trough 4112. The sliding member 41 is close to the side of the second rotating part 22. A second cam portion 412 is provided, and the second cam portion 412 has a second wave peak 4121 and a second wave valley 4122;

When the folding device 1 is in the unfolded state, the first wave crest 4111 corresponds to the second wave trough 4122, and the first wave trough 4112 corresponds to the second wave crest 4121; when the folding device 1 is folded and the first rotating member 20 rotates relative to the base 10 by default angle, the first wave crest 4111 contacts the second wave crest 4121, the first wave trough 4112 corresponds to the second wave trough 4122, causing the sliding member 41 to slide and thereby compressing the first elastic member 42.

In order to realize the above hovering function, in this embodiment, a first cam part 411 can be provided on the other side of the second rotating part 22, and a second cam part 412 can be provided on the side of the sliding member 41 close to the second rotating part 22, that is, A second cam portion 412 is provided on the side of the sliding member 41 facing the second rotating portion 22 . The first cam part 411 has a first wave peak 4111 and a first wave valley 4112, and the second cam part 412 has a second wave peak 4121 and a second wave valley 4122. The crest refers to the more convex and higher part of the cam part, and the trough refers to the lower part of the cam part.

When the folding device 1 is in the unfolded state, the first cam part 411 contacts the second cam part 412. At this time, the first wave crest 4111 can correspond to the second wave trough 4122, and the first wave trough 4112 can correspond to the second wave crest 4121, that is, the wave crests and troughs are mutually opposite. Staggered settings. At this time, the distance between the first wave trough 4112 and the second wave trough 4122 is shorter. When the folding device 1 moves from the unfolded state to the folded state, the first wave peak 4111 gradually moves from the position corresponding to the second wave valley 4122 along the slope between the second wave valley 4122 and the second wave peak 4121 toward the second wave peak 4121 Climbing the slope, at this time, the distance between the first wave valley 4112 and the second wave valley 4122 gradually increases, which causes the sliding member 41 with the second cam to gradually slide in the direction away from the first rotating member 20, that is, close to the sliding space. 14 slides in the direction of the groove wall, causing the first elastic member 42 to gradually compress. When the first rotating member 20 rotates at a preset angle relative to the base 10 , for example, 30°, the first wave peak 4111 completes the climb and abuts the second wave peak 4121 , and the first wave valley 4112 corresponds to the second wave valley 4122 . At this time, the distance between the first wave valley 4112 and the second wave valley 4122 is the largest, the sliding distance of the sliding member 41 is the largest, and the compression amount of the first elastic member 42 reaches the maximum. In other words, the elastic force of the first elastic member 42 maximizes the friction force between the sliding member 41 and the second rotating part 22 of the first rotating member 20 . When the first rotating member 20 stops rotating at this time, the friction force can be used to make the The first rotating member 20 is in a stationary state and realizes the hovering function. Moreover, in this embodiment, the first rotating member 20 and the first cam part 411 are integrated together, and the sliding member 41 and the second cam part 412 are integrated together, which can save the number of parts.

In addition, since the sliding member 41 can also abut the second rotating part 22 of the second rotating member 20', two second cam parts 412 can be provided on the sliding member 41, and the second rotating part 22 of the second rotating member 20' The first cam part 411 is also provided on the first cam part 411, and the hovering function is achieved through the cooperation of the wave peaks and the wave troughs between the first cam part 411 and the second cam part 412. This embodiment will not be described again here.

Please refer to Figures 20 to 24 again. In this embodiment, the first wave peak 4111 has a first plane 4113, and the second wave peak 4121 has a second plane 4123. When the folding device 1 is folded, the first rotating member 20 is relative to the base 10 When rotating at a preset angle, the first plane 4113 abuts the second plane 4123, so that when the first rotating member 20 stops rotating, the first rotating member 20 is in a stationary state relative to the base 10 .

In this embodiment, a first plane 4113 can be provided on the first wave crest 4111, and a second plane 4123 can be provided on the second wave crest 4121, so that when the folding device 1 is folded and the first rotating member 20 rotates at a preset angle relative to the base 10, The first plane 4113 of the first wave peak 4111 can be made to contact the second plane 4123 of the second wave peak 4121, which not only improves the stability of hovering, but also increases the hovering angle range of the first rotating member 20, further improving the hovering ability. Effect. The shape and size of the plane can be set according to the actual needs of hovering.

FIG. 28 is a schematic cross-sectional view of the base, the first rotating member, the second rotating member, and the synchronization mechanism shown in FIG. 26 . In this embodiment, the folding device 1 further includes a synchronization mechanism 50. The synchronization mechanism 50 includes a first synchronization member 51 and a second synchronization member 52 that are rotationally connected. One end of the first synchronization member 51 is connected to the first rotating member 20, and the second synchronization member 51 is connected to the first rotating member 20. One end of the member 52 is connected to the second rotating member 20', and the other ends of the first synchronizing member 51 and the second synchronizing member 52 are both rotatably connected to the base 10. The rotation of the first rotating member 20 can drive the first synchronizing member 51 to rotate, and drive the second synchronizing member 52 to rotate synchronously, thereby driving the second rotating member 20' to rotate synchronously and reversely relative to the first rotating member 20.

In addition to the above-mentioned components, the folding device 1 may also include a synchronization mechanism 50. The synchronization mechanism 50 is mainly used to rotate the first rotating member 20 and the second rotating member 20' synchronously and in opposite directions. Specifically, the synchronization mechanism 50 may include a first synchronization member 51 and a second synchronization member 52 that are rotationally connected. One end of the first synchronization member 51 is connected to the first rotating member 20, and one end of the second synchronizing member 52 is connected to the second rotating member 20'. , the other ends of the first synchronizing member 51 and the second synchronizing member 52 are both rotatably connected to the base 10 . The above-mentioned connection can be a direct connection, a rotational connection, or a rotational and sliding connection. This embodiment is not limited here, as long as it is ensured that the first rotating member 20 can drive the first synchronizing member 51 to rotate when it rotates. , the rotation of the second rotating member 20' can drive the second synchronizing member 52 to rotate.

Alternatively, in one embodiment, the first synchronizing member 51 may be directly rotatably connected to the second synchronizing member 52 . In other embodiments, the first synchronizing member 51 and the second synchronizing member 52 may be rotationally connected through other components, such as the third synchronizing member 53 .

Regardless of whether the folding device 1 is folded or unfolded, that is, whether the folding device 1 is in the process from the unfolded state to the folded state or from the folded state to the unfolded state, the first rotating member 20 will rotate relative to the base 10, thereby driving the The first synchronizing member 51 connected to the first rotating member 20 rotates relative to the base 10 . Since the first synchronizing part 51 is rotationally connected to the second synchronizing part 52, the first synchronizing part 51 can drive the second synchronizing part 52 to rotate synchronously, and then drive the second connecting part connected to the second synchronizing part 52 to rotate, and the second rotating part The member 20' rotates synchronously and reversely relative to the first rotating member 20, thereby realizing the synchronous rotation of the first rotating member 20 and the second rotating member 20', ensuring the stability of the appearance and performance of the folding device 1 during the folding process.

Of course, in this embodiment, the first rotating member 20 starts to rotate and finally the second rotating member 20' rotates synchronously for schematic explanation. In other embodiments, the second rotating member 20' may also start to rotate and finally cause the first rotating member 20 to rotate synchronously. Refer to the above content for the specific process, which will not be described again in this embodiment.

Optionally, in this embodiment, the first synchronizing member 51 and the base 10 can be cooperatively connected through the first rotation shaft and the first rotation hole, thereby realizing the first synchronizing member 51 to be rotationally connected to the base 10 . Among them, the first rotation shaft is provided in one of the first synchronization member 51 and the base 10 , and the first rotation hole is provided in the other one of the first synchronization member 51 and the base 10 . For example, when the first rotation shaft is provided on the first synchronizing member 51 , the first rotation hole is provided on the base 10 . When the first rotation hole is provided in the base 10 , the first rotation shaft is provided in the first synchronizing member 51 . This embodiment is only schematically described by assuming that the first rotation shaft is provided in the first synchronizing member 51 and the first rotation hole is provided in the base 10 .

Optionally, in this embodiment, the second synchronizing member 52 and the base 10 can be cooperatively connected through the second rotating shaft and the second rotating hole, thereby realizing the second synchronizing member 52 to be rotationally connected to the base 10 . Wherein, the second rotation shaft is provided in one of the second synchronizing member 52 and the base 10 , and the second rotation hole is provided in the other one of the second synchronizing member 52 and the base 10 . For example, when the second rotation shaft is provided on the second synchronizing member 52 , the second rotation hole is provided on the base 10 . When the second rotation hole is provided in the base 10 , the second rotation shaft is provided in the second synchronizing member 52 . This embodiment is only schematically described by assuming that the second rotation shaft is provided in the second synchronizing member 52 and the second rotation hole is provided in the base 10 .

Please refer to Figures 5 and 26-28 again. In this embodiment, the synchronization mechanism 50 also includes a plurality of third synchronization parts 53. The plurality of third synchronization parts 53 are rotatably connected to the first synchronization part 51 and the second synchronization part 52. , the rotation of the first synchronization member 51 can drive the rotation of a plurality of third synchronization members 53 , thereby driving the second synchronization member 52 to rotate synchronously and in the opposite direction relative to the first synchronization member 51 .

In addition to the first synchronization part 51 and the second synchronization part 52, the synchronization mechanism 50 may also include a plurality of third synchronization parts 53, and the plurality of third synchronization parts 53 are used to rotationally connect the first synchronization part 51 and the second synchronization part 52, Thus, the first synchronizing member 51 is indirectly connected to the second synchronizing member 52 by rotation. When the first synchronizing part 51 rotates relative to the base 10, it can drive a plurality of third synchronizing parts 53 to rotate relative to the base 10, thereby driving the second synchronizing parts 52 to rotate synchronously, and the second synchronizing parts 52 rotate relative to the first synchronizing part 51. The synchronous and reverse rotation ultimately drives the second rotating member 20' to rotate synchronously and reversely relative to the first rotating member 20.

Optionally, the synchronization mechanism 50 further includes two third synchronization parts 53 , and the two third synchronization parts 53 are rotationally connected between the first synchronization part 51 and the second synchronization part 52 . The first synchronizing member 51 is rotatably connected to a third synchronizing member 53 , the third synchronizing member 53 is rotatably connected to the other third synchronizing member 53 , and the other third synchronizing member 53 is rotatably connected to the second synchronizing member 52 .

Further optionally, the third synchronizing member 53 includes but is not limited to size. A plurality of teeth are provided correspondingly to at least part of the circumferential sides of the first synchronizing member 51 and the second synchronizing member 52 .

Optionally, the third synchronizing member 53 is cooperatively connected with the base 10 through the third rotation shaft and the third rotation hole, so that the third synchronizing member 53 is rotationally connected to the base 10 . Among them, the third rotation axis is provided in one of the third synchronization member 53 and the base 10 , and the third rotation hole is provided in the other one of the third synchronization member 53 and the base 10 . For example, when the third rotation shaft is provided on the third synchronizing member 53 , the third rotation hole is provided on the base 10 . When the third rotation hole is provided in the base 10 , the third rotation shaft is provided in the third synchronizing member 53 . This embodiment is only schematically described by assuming that the third rotation axis is provided in the third synchronizing member 53 and the third rotation hole is provided in the base 10 .

Optionally, the base 10 has a third rotation space 15. The first synchronization member 51, the second synchronization member 52, and even a plurality of third synchronization members 53 are disposed in the third rotation space 15, so that various components can be further integrated. They are all integrated on the base 10 , which simplifies the structure of the folding device 1 and reduces the size of the folding device 1 .

Please refer to Figures 26 to 28 again. In this embodiment, the second rotation axis C2 between the first rotating member 20 and the base 10 and the third rotation axis between the first synchronizing member 51 and the base 10 The center lines C3 do not overlap, and one end of the first synchronizing member 51 is slidably and rotationally connected to the first rotating member 20 .

It can be seen from the above that the first rotating member 20 is rotationally connected to the base 10 , so there is a second rotation axis C2 between the first rotating member 20 and the base 10 . Similarly, the first synchronizing member 51 is rotatably connected to the base 10 , so there is a third rotation axis C3 between the first synchronizing member 51 and the base 10 . In this embodiment, the second rotation axis C2 and the third rotation axis C3 do not overlap. The above-mentioned non-coincidence can be understood as the second rotation axis C2 and the third rotation axis C3 are parallel to each other, that is, the extension direction of the second rotation axis C2 and the extension direction of the third rotation axis C3 are the same, and there is a certain distance between the second rotation axis C2 and the third rotation axis C3.

The above design can prevent the first rotating member 20 from rotating relative to the base 10 when the folding device 1 is in a stationary state, that is, when the folding device 1 is not rotating, which improves the stability of the folding device 1 . However, when the folding device 1 moves, the first rotating member 20 can rotate relative to the base 10 and can still drive the first synchronizing member 51 to rotate relative to the base 10 . As for the specific positions of the second rotation axis C2 and the third rotation axis C3, this embodiment is not limited here.

In addition, when the second rotation axis C2 and the third rotation axis C3 do not coincide with each other, in this embodiment, one end of the first synchronization member 51 can be slid and rotationally connected to the first rotation member 20, thereby utilizing the first synchronization. The member 51 can slide relative to the first rotating member 20 to compensate for the displacement difference caused by the misalignment of the axis center lines when rotating at the same angle, and prevent the first rotating member 20 from interfering with the first synchronizing member 51 .

Please refer to FIGS. 29 and 30 together. FIG. 29 is a schematic diagram of the cooperation between the first synchronizing member and the first rotating member in an embodiment of the present application. FIG. 30 is an exploded schematic view of the first synchronizing component and the first rotating component shown in FIG. 29 . In this embodiment, one end of the first synchronizing member 51 and the first rotating member 20 are cooperatively connected through the second rolling shaft 510 and the second rolling groove 511. The second rolling shaft 510 is provided between the first synchronizing member 51 and the first rotating member. In one of the first synchronizing parts 51 and the first rotating part 20 , the second rolling groove 511 is provided in the other one.

In this embodiment, one end of the first synchronizing member 51 and the first rotating member 20 are cooperatively connected through the second rolling shaft 510 and the second rolling groove 511, thereby realizing the first synchronizing member 51 to be slidably and rotationally connected to the first rotating member 20. . For example, when the second rolling shaft 510 is provided on the first synchronizing member 51 , the second rolling groove 511 is provided on the first rotating member 20 . When the second rolling shaft 510 is provided on the first rotating member 20 , the second rolling groove 511 is provided on the first synchronizing member 51 . This embodiment is only schematically described by assuming that the second rolling shaft 510 is provided on the first synchronizing member 51 and the second rolling groove 511 is provided on the first rotating member 20 . The second rolling shaft 510 can rotate relative to the second rolling groove 511 to cause the first synchronizing member 51 to rotate relative to the first rotating member 20. At the same time, the second rolling shaft 510 can also slide in the second rolling groove 511, so that the A synchronizing member 51 slides relative to the first rotating member 20 , so that the first synchronizing member 51 slides and rotates relative to the first rotating member 20 . Optionally, the second rolling axis 510 includes but is not limited to a pin.

Optionally, the second rolling shaft 510 and the first rotating member 20 or the first synchronizing member 51 may be fixedly connected or rotationally connected. example For example, in this embodiment, the second rolling shaft 510 is provided on the first synchronizing member 51. The second rolling shaft 510 can be fixed on the first synchronizing member 51 so that the second rolling shaft 510 and the first synchronizing member 51 remain relatively stationary. As a result, the second rolling groove 511 slides and rotates relative to the second rolling shaft 510 . Or the second rolling shaft 510 can also be rotatably connected to the first synchronizing member 51 so that the second rolling shaft 510 and the first synchronizing member 51 maintain relative rotation, so that the second rolling groove 511 can still slide relative to the second rolling shaft 510 and turn. Further optionally, when the second rolling shaft 510 is fixed on the first synchronizing member 51 , the second rolling shaft 510 and the first synchronizing member 51 may have an integrated structure or a split structure. Specifically, in this embodiment, the second rolling shaft 510 can be installed on the first synchronizing member 51 by inserting the shaft.

Optionally, the first rotating member 20 has a fourth rotating space 23. The fourth rotating space 23 is used to accommodate the first synchronizing member 51 and the second rolling shaft 510, and is reserved for the sliding and rotation of the first synchronizing member 51. space to prevent the first synchronizing member 51 from interfering with the first rotating member 20 .

Please refer to FIG. 28 and FIG. 31 together. FIG. 31 is a schematic cross-sectional view of the first rotating member and the first synchronizing member when the folding device is in a folded state according to an embodiment of the present application. In this embodiment, the first rotating member 20 has a fixed surface 24, and the second rolling groove 511 has a third limiting end 5111 and a fourth limiting end 5112 arranged oppositely. The third limiting end 5111 is smaller than the fourth limiting end 5111. The position end 5112 is further away from the base 10 , and the third limiting end 5111 is farther away from the fixing surface 24 than the fourth limiting end 5112 . When the folding device 1 is in the unfolded state, the second rolling shaft 510 is positioned at the third limiting end 5111. When the folding device 1 is in the folded state, the second rolling shaft 510 is positioned at the fourth limiting end 5112.

The first rotating part 20 has a fixing surface 24 for fixing to the housing, that is, the lower surface of the first rotating part 20 . In other words, the fixed surface 24 of the first rotating member 20 is the fixed surface 24 of the fixed part 21 . The second rolling groove 511 has two opposite ends: a third limiting end 5111 and a fourth limiting end 5112. Since the second rolling shaft 510 slides in the second rolling groove 511, the third limiting end can be used. The side walls of the position end 5111 and the fourth limit end 5112 limit the sliding of the second rolling shaft 510, so that the sliding of the second rolling shaft 510 stops when it slides to the third limit end 5111 and the fourth limit end 5112. Can't slide any further. As shown in Figure 28, when the folding device 1 is in the unfolded state, the third limiting end 5111 is further away from the base 10 than the fourth limiting end 5112, that is, the third limiting end 5111 is farther away from the base 10 than the fourth limiting end 5112. The end is further to the right. At the same time, the third limiting end 5111 is further away from the fixed surface 24 than the fourth limiting end 5112. That is, the third limiting end 5111 is higher than the fourth limiting end 5112. Therefore, the third limiting end 5111 is located at In the upper right position, the fourth limiting end 5112 is located in the lower left position.

During the movement of the folding device 1, as shown in Figure 28, when the folding device 1 is in the unfolded state, the second rolling shaft 510 is positioned at the third limiting end 5111. As shown in Figure 31, when the folding device 1 is in the folded state, the second rolling shaft 510 is positioned at the fourth limiting end 5112. In other words, the second rolling axis 510 is located on the upper right when the folding device 1 is in the unfolded state, and the second rolling axis 510 is located on the lower left when the folding device 1 is in the folded state.

Therefore, during the process of the folding device 1 from the unfolded state to the folded state, the first rotating member 20 rotates relative to the base 10. At this time, the first rotating member 20 drives the first synchronizing member 51 to rotate relative to the base 10. At the same time, the first synchronizing member 51 rotates relative to the base 10. 51 rotates and slides relative to the first rotating member 20, thereby causing the position of the second rolling shaft 510 to change, so that it can move from the third limiting end 5111 to the fourth limiting end 5112, or in other words, the second rolling shaft 510 moves at the third limiting end 5111 to the fourth limiting end 5112. The two rolling grooves 511 move from the upper right to the lower left direction to adapt to the displacement difference caused by rotation when the second rotation axis C2 and the third rotation axis C3 do not coincide with each other.

Please refer to FIG. 32 , which is a schematic cross-sectional view of the first rotating member in an embodiment of the present application. In this embodiment, the second rolling groove 511 also has a third communication part 5113 that connects the third limiting end 5111 and the fourth limiting end 5112. The distance between the third connecting part 5113 and the fixed surface 24 is from close to the third connecting part 5113. The limiting end 5111 gradually decreases toward the fourth limiting end 5112.

The second rolling groove 511 is a chute 414 with a certain length. Therefore, in addition to the third limiting end 5111 and the fourth limiting end 5112, the second rolling groove 511 also has a connecting third limiting end 5111 and a fourth limiting end. The third communication portion 5113 of the end 5112 and the first rolling shaft 320 are located in the third communication portion 5113 in other states except the unfolded state and the folded state. This embodiment can make the connection between the third communication portion 5113 and the fixed surface 24 The distance between them gradually decreases from close to the third limiting end 5111 to close to the fourth limiting end 5112. It can also be understood that the shape of the third communication portion 5113 is a straight line, and the third communication portion 5113 extends from the upper right to the seated position. This can simplify the structure of the second rolling groove 511, allowing the second rolling shaft 510 to directly slide one of the two limiting ends to the other of the two limiting ends through the linear third connecting portion 5113.

Of course, in other embodiments, the shape of the third communication part 5113 may also be arc-shaped or other shapes, as long as the positions of the third limiting end 5111 and the fourth limiting end 5112 are ensured to meet the above position limitations.

Please refer to Figure 32 again. In this embodiment, the second rolling groove 511 satisfies at least one of the following conditions: the second rolling groove 511 also has a fourth connecting portion that connects the third connecting portion 5113 and the third limiting end 5111. 5114, the extending direction of the fourth communication portion 5114 is parallel to the fixing surface 24. The second rolling groove 511 also has a fifth communication portion 5115 that communicates with the third communication portion 5113 and the fourth limiting end 5112 . The extension direction of the fifth communication portion 5115 is parallel to the fixing surface 24 .

In addition to the third limiting end 5111, the fourth limiting end 5112, and the third communication part 5113, the second rolling groove 511 may also include a fourth communication part 5114 that connects the third communication part 5113 and the third limiting end 5111. , that is, there is a fourth communication portion 5114 between the third communication portion 5113 and the third limiting end 5111 . In other words, during the process of the folding device 1 from the unfolded state to the folded state, the second rolling shaft 510 does not move directly from the third limiting end 5111 to the third communication part 5113, but is first located at the fourth communication part 5114, and then Moving to the third communication part 5113.

In this embodiment, the extension direction of the fourth communication portion 5114 can be parallel to the fixing surface 24 , that is, the extension direction of the second communication portion 3214 is horizontal. In this way, the horizontal fourth communication portion 5114 can be used when the folding device 1 is in the unfolded state. To support the second rolling shaft 510 and prevent the second rolling shaft 510 from moving from the third limiting end 5111 to the third connecting portion 5113 by itself, thereby improving the stability of the folding device 1 . In addition, the horizontal fourth communication portion 5114 can also reduce the gap between the second rolling shaft 510 and the second rolling groove 511 to prevent the existence of empty positions.

In the same way, the second rolling groove 511 may also include a fifth communication part 5115 that connects the third communication part 5113 and the fourth limiting end 5112. That is, there is a fifth communication part 5115 between the third communication part 5113 and the fourth limiting end 5112. Connectivity 5115. In other words, during the process of the folding device 1 from the unfolded state to the folded state, the second rolling shaft 510 does not directly move from the third communication part 5113 to the fourth limiting end 5112, but is first located at the fifth communication part 5115, and then Then move to the fourth limiting end 5112.

In this embodiment, the extension direction of the fifth communication portion 5115 can be parallel to the fixing surface 24 , that is, the extension direction of the fifth communication portion 5115 is horizontal. In this way, the horizontal fifth communication portion 5115 can be used when the folding device 1 is in the unfolded state. To support the second rolling shaft 510 and prevent the second rolling shaft 510 from moving from the fourth limiting end 5112 to the third connecting portion 5113 by itself, thereby improving the stability of the folding device 1 . In addition, the fifth horizontal connecting portion 5115 can also reduce the gap between the second rolling shaft 510 and the second rolling groove 511 to prevent the existence of empty positions.

It is worth noting that in the second rolling groove 511, the fourth communication part 5114 and the fifth communication part 5115 may exist alone or at the same time. For example, the second rolling groove 511 may only include the fourth communication part 5114, or the second rolling groove 511 may only include the fifth communication part 5115, or the second rolling groove 511 may include both the fourth communication part 5114 and the fifth communication part 5115. .

Please refer to Figure 1, Figure 3-4, and Figure 8 together. In this embodiment, the folding device 1 also includes a third support member 60. When the folding device 1 is in the unfolded state, the third support member 60 is disposed on part of the between the first support member 30 and part of the second support member 30'. When the folding device 1 is folded, the first support member 30 and the second support member 30 ′ rotate relative to the base 10 , and the third support member 60 moves toward the base 10 . When the folding device 1 is unfolded, the first support member 30 and the second support member 30 ′ rotate relative to the base 10 , and the third support member 60 moves away from the base 10 .

In addition to the first support member 30 and the second support member 30', the folding device 1 may also include a third support member 60. The third support member 60 has the same function as the first support member 30 and the second support member 30', and is used to support the flexible member 80. Therefore, the third support member 60 also has a support surface 310. When the folding device 1 is in the unfolded state, the third supporting member 60 is provided between part of the first supporting part 30 and part of the second supporting part 30'. Optionally, the supporting surface 310 of the first supporting member 30 , the supporting surface 310 of the second supporting member 30 ′, and the supporting surface 310 of the third supporting member 60 are arranged flush, which can further improve the flatness of the folding device 1 , and further improve the flatness of the folding device 1 . Support the flexible member 80 well.

When the folding device 1 is folded, it can be seen from the above that the first support member 30 and the second support member 30' fold and rotate relative to the base 10, thereby driving the two ends of the flexible member 80 to fold with each other. However, sometimes the middle part of the flexible member 80 sinks when the two ends of the flexible member 80 are folded with each other, that is, the middle part moves toward the base 10 . Therefore, this embodiment can move the third support member 60 in a direction close to the base 10 to avoid the middle part of the flexible member 80 and prevent the flexible member 80 and the third support member 60 from interfering with each other. Finally, the folding device 1 is in the folded state. The flexible member 80 has a receiving space 11 in a desired shape.

When the folding device 1 is unfolded, the first support member 30 and the second support member 30' unfold and rotate relative to the base 10, driving the two ends of the flexible member 80 to unfold each other. At this time, the middle part of the flexible member 80 will move from the sunken position. Move away from the base 10 and return to the initial position. At this time, the third support member 60 can be moved in a direction away from the base 10 , so that when the folding device 1 is in the unfolded state, the third support member 60 is still used to support the flexible member 80 .

Optionally, as shown in FIG. 3 , the third support member 60 is provided with a guide shaft 600 , and the base 10 is provided with a guide space 601 . The guide shaft 600 is disposed in the guide space 601 to achieve the guiding function.

Please refer to FIG. 5 , FIG. 33 and FIG. 34 together. FIG. 33 is a schematic cross-sectional view of the folding device in an unfolded state according to an embodiment of the present application. Figure 34 is a schematic cross-sectional view of the folding device in a folded state according to an embodiment of the present application. In this embodiment, the base 10 has a through hole 16, and the folding device 1 also includes a moving member 61 and a second elastic member 62. The moving member 61 is connected to the side of the third support member 60 close to the base 10, and the second elastic member 62 The opposite ends contact the moving member 61 and the hole wall of the through hole 16 respectively. When the folding device 1 is in the unfolded state, the second elastic member 62 is in a compressed state. When the folding device 1 is folded, the second elastic member 62 moves the moving member 61 away from the first supporting member 30 and the second supporting member 30 ′, and then moves the third supporting member 60 toward the base 10 .

In order to realize the above movement process, the folding device 1 of this embodiment may further include a moving member 61 and a second elastic member 62 . The base 10 is provided with a through hole 16 , and the moving member 61 can be connected to the side of the third support member 60 close to the base 10 through the through hole 16 . In other words, the moving member 61 is located on the side of the third supporting member 60 away from the supporting surface 310 . In addition, the opposite ends of the second elastic member 62 contact the moving member 61 and the hole walls of the through hole 16 respectively. When the folding device 1 is in the unfolded state, the second elastic member 62 is in a compressed state. In other words, since the base 10 is stationary, the elastic force of the second elastic member 62 will give the moving member 61 a distance away from the first support member 30 and the second support. The force in the direction of component 30' is the downward force.

In this way, when the folding device 1 is folded, the second elastic member 62 can give the above-mentioned force to move the moving member 61 in a direction away from the first supporting member 30 and the second supporting member 30', that is, the moving member 61 moves downward. . Since the moving member 61 is connected to the third supporting member 60 , the moving member 61 can drive the third supporting member 60 to move downward, that is, the third supporting member 60 moves toward the base 10 to avoid the flexible member 80 .

Please refer to Figure 4 and Figure 8 again. In this embodiment, the first support member 30 and the second support member 30' both include a connected support part 31 and a rolling part 32. The rolling part 32 is slidably and rotationally connected to the base 10 , when the folding device 1 is in the unfolded state, the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' are both in contact with the surface of the third supporting member 60 close to the base 10. When the folding device 1 is folded, the rolling portion 32 of the first supporting member 30 is separated from the rolling portion 32 of the second supporting member 30' and the third supporting member 60, thereby causing the third supporting member 60 to move toward the base 10 direction movement. When the folding device 1 is unfolded, the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' can contact the surface of the third supporting member 60 close to the base 10, and push the third supporting member 60 toward the base 10. The member 60 faces away from the base 10 move towards.

The first support member 30 and the second support member 30' each include a connected support portion 31 and a rolling portion 32, and the rolling portion 32 is provided on a side of the supporting portion 31 close to the base 10. The supporting part 31 and the rolling part 32 have been described in detail above, and will not be described again in this embodiment. In this embodiment, when the folding device 1 is in the unfolded state, the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' are both in contact with the third supporting member 60 on the side close to the base 10 surface. That is, the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' are both in contact with the lower surface of the third supporting member 60 that is away from the supporting surface 310. In this way, the two rolling parts 32 can be used to support the third support member 60 to prevent the third support member 60 from moving downward under the action of the second elastic member 62 in the unfolded state, thus ensuring the structural stability of the folding device 1 .

When the folding device 1 is folded, the first support member 30 and the second support member 30' are folded close to each other, that is, the support portion 31 of the first support member 30 and the support portion 31 of the second support member 30' are folded close to each other. However, since the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' are slidingly and rotationally connected to the base 10, the two rolling portions 32 and the two supporting portions 31 are opposite to each other. The rolling parts 32 are spread apart from each other. And the two rolling parts 32 rotate in the direction away from the third supporting member 60 , so the rolling part 32 of the first supporting part 30 and the rolling part 32 of the second supporting part 30 ′ are separated from the lower surface of the third supporting part 60 . At this time, since the third support member 60 does not have the support of the two rolling parts 32, the third support member 60 can be driven by the moving member 61 and the second elastic member 62 to move in the same movement process mentioned above. The third support member 60 is moved toward the direction close to the base 10 .

On the contrary, when the folding device 1 is unfolded, the first support member 30 and the second support member 30' are deployed away from each other, that is, the support portion 31 of the first support member 30 and the support portion 31 of the second support member 30' are deployed away from each other. However, since the rolling portion 32 of the first supporting member 30 and the rolling portion 32 of the second supporting member 30' are slidingly and rotationally connected to the base 10, the two rolling portions 32 and the two supporting portions 31 are opposite to each other. The rolling parts 32 are folded close to each other. And the two rolling parts 32 rotate in a direction close to the lower surface of the third support member 60 until the two rolling parts 32 abut against the lower surface of the third support member 60 . Then, when the two rolling parts 32 continue to rotate closer to each other, they can drive the third support member 60 to move in a direction away from the base 10 to the initial position. At the same time, the moving member 61 is moved in a direction close to the first supporting member 30 and the second supporting member 30', and the second elastic member 62 is put into a compressed state again.

In summary, this embodiment utilizes the support portion 31 of the first support member 30 and the support portion 31 of the second support member 30' to support the third support member 60 when the folding device 1 is in the unfolded state. And when the folding device 1 is unfolded, the third support member 60 is returned to its position. When the folding device 1 is folded, the movement of the third support member 60 relies on the cooperation between the moving member 61 and the second elastic member 62 .

In this embodiment, pressing portions 63 may be protrudingly provided on opposite sides of the third support member 60 . And when the folding device 1 is in the unfolded state, the pressing portion 63 is closer to the base 10 than the first supporting member 30 and the second supporting member 30', that is, the pressing portion 63 is located between the first supporting member 30 and the second supporting member. 30' below.

In this way, when the folding device 1 is folded, the parts of the first support member 30 and the second support member 30' that are far away from each other will rotate upward toward each other, and the parts of the first support member 30 and the second support member 30' that are close to each other will face downward. rotate away from each other. Therefore, when the parts of the first support member 30 and the second support member 30' that are close to each other rotate downward, they will contact and press the pressing portion 63, thereby driving the pressing portion 63 to move in a direction closer to the base 10, that is, The third support member 60 is driven to move toward the direction close to the base 10 .

To sum up, this application can not only use the moving member 61 and the second elastic member 62 to move the third support member 60 in the direction close to the base 10, but also use the first support member 30 and the second support member 30' to press.

Finally, when the first housing 71 is rotated 90°, the flexible members 80 in the non-bending areas 801 of the first housing 71 and the second housing 72 abut each other, so that the electronic device 3 is between the first housing 71 and the second housing 72 . There is no gap at the second housing 72 and can achieve complete contact, which not only effectively protects the flexible member 80 but also reduces the thickness of the electronic device 3 . The flexible member 80 of the bending area 800 on the folding device 1 forms a water drop shape with a small top and a large bottom.

When the electronic device 3 wants to return to the unfolded state from the folded state, the user only needs to pull the first housing 71 outward to cause the first housing 71 and the second housing 72 to rotate in opposite directions, driving the first housing 71 and the second housing 72 to rotate in the opposite direction. The first rotating member 20 on a housing 71 and the second rotating member 20' fixed on the second housing 72 rotate in reverse direction relative to the base 10, thereby driving the first supporting member 30 and the second supporting member 30.

Then, the first support member 30 and the second support member 30' are moved away from each other, and finally the two ends of the flexible member 80 are also unfolded away from each other, exposing the display surface 802 of the flexible member 80, thereby realizing the folding function of the electronic device 3. Finally, when the first housing 71 is reversely rotated 90°, the first support member 30 and the second support member 30' return to a fully expanded state, and the flexible member 80 also returns to a flush shape.
