Detailed ways

In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present application will be described in further detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integration; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediary, and it can be the internal communication of two elements or the interaction relationship between two elements. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model in specific situations.

In the present application, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include that the first and second features are in direct contact, and may also include that the first and second features are not in direct contact but are in contact with another feature between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

The designer found that in the existing vibration feedback device, the contact panel and the device shell are connected by a spring. During the vibration process, the vibration energy will be transmitted to the shell or base through the spring. Since the shell or base will provide a connection interface with other components, if too much energy is transmitted to the shell or base, it will also bring vibration to the shell or base, and it will hit the connected parts on the interface. On the one hand, it will emit noise, and on the other hand, it will also cause wear to the interface. Based on this, the present application designs a combination of a spring structure and a damping device to solve the above technical problems.

As shown in FIGS. 1-20 , the embodiment of the present application provides a vibration feedback device based on a spring and damping structure, including: a touch panel 100 for touch operation. During use, the touch panel 100 is usually contacted with a finger or a stylus, so that the touch panel 100 obtains a touch signal to realize touch operation;

a device housing 200, the touch panel 100 is mounted on the device housing 200;

The actuator 300 is arranged on the inner surface of the touch panel 100, and is used to drive the touch panel 100 to reciprocate and vibrate along the first direction;

The connecting device connects the touch panel 100 and the device casing 200, including a spring device 400 and a damping device 500, the spring device 400 and the damping device 500 are configured to support the touch panel 100 along the first direction, and the damping device 500 can absorb the vibration energy transmitted from the touch panel 100 to the device casing 200.

In this solution, the actuator 300 is set to drive the touch panel 100 to vibrate in the first direction, and the spring device 400 and the damping device 500 are set to support the touch panel 100 in the same direction. When the touch panel 100 moves toward the device housing 200, the spring device 400 and the damping device 500 are compressed, and the vibration energy is absorbed by the damping device 500, so that the vibration energy transmitted to the device housing 200 is reduced, thereby achieving the purpose of reducing the vibration of the device housing 200.

On the other hand, the energy absorbed during the compression process of the damping device 500 is released during the subsequent vibration of the touch panel 100 to a side away from the device housing 200, and its force is applied to the touch panel 100, thereby strengthening the vibration feedback received by the touch panel 100 and making the user experience better.

As a preferred embodiment, both the spring device 400 and the damper device 500 adopt a slender structure. Under this structure, the length direction of the spring device 400 and the damper device 500 is arranged parallel to the first direction, that is, both the spring device 400 and the damper device 500 are compressed or expanded in their length direction to achieve the desired technical effect of the present application.

The aforementioned spring device 400 and damper device 500 are elongated structures and are not intended to limit this application. In other embodiments of this application, spring devices 400 and damper devices 500 in other forms can also be used according to application scenarios, space, and application product structure constraints.

It should be pointed out that, depending on the direction in which the vibration feedback is required, the connecting device, the device housing 200 and the touch panel 100 may be in different relative positions.

In this solution, the actuator 300 refers to a driving device capable of converting electrical energy or other energy into mechanical energy.

Referring to FIGS. 1 , 3 , 4 , 7 , and 8 , in a preferred embodiment of the present application, the first direction is defined as a pressing direction for the touch panel 100 . In this case, the direction of the vibration feedback is on the same line as the pressing direction.

Specifically, in this embodiment and other solutions of the present application, the touch panel 100 has a touch surface facing the operator and an inner surface facing away from the touch surface. Under the above structure, in this embodiment, the actuator 300 is arranged on the inner surface. The connection device is located between the inner surface and the device housing 200 , and the two ends of the spring device 400 are respectively connected to the inner surface of the contact panel 100 and the device housing 200 .

Under the above arrangement structure, there is no need to provide a support structure at the touch surface. Therefore, when the touch panel 100 moves away from the device housing 200, the compressed spring restoring force is superimposed on the vibration driving force of the actuator 300, so that the vibration amplitude of the touch panel 100 in this direction can be larger, thereby reducing the vibration transmitted to the device housing 200 and allowing a stronger vibration feeling to be transmitted to the operator, so that the operator feels stronger vibration feedback.

Referring to FIGS. 2 , 5 , and 6 , in another preferred embodiment of the present application, the first direction is defined to be perpendicular to the direction of pressing the touch panel 100 . In this case, the direction of vibration feedback is perpendicular to the pressing direction. In this solution, the touch panel 100 not only has a touch surface facing the operator and an inner surface away from the touch surface, but also needs to have a side surface connecting the touch surface and the inner surface at the periphery, and the side surface needs to have a certain thickness, so that the connecting device can be arranged between the side surface and the device housing 200, and the two ends of the spring device 400 are respectively connected to the side surface of the touch panel 100 and the device housing 200.

It should be pointed out that the side surface of the above-mentioned touch panel 100 has a certain thickness so that the connection device can be installed, which is not a limitation to the present application. In other embodiments, when the thickness of the touch panel 100 does not meet the conditions for installing the connection device or when the structural constraints of the rest make it inconvenient to directly connect the connection device to the above-mentioned side surface, an auxiliary support structure can be used to connect the touch panel 100 and the connection device.

For example, as shown in FIGS. 5 and 6, a mounting bracket 600 is provided on the inner surface of the touch panel 100, the mounting bracket 600 has a mounting portion 620 perpendicular to the first direction, and the two ends of the spring device 400 are respectively connected to the inner surface of the device housing 200 and the mounting portion 620.

By setting the installation bracket 600 above, the connection device is connected to the touch panel 100 through the installation bracket 600, which reduces the structural restrictions on the touch panel 100 and reduces the difficulty of installing the connection device.

Specifically, the mounting bracket 600 in this solution includes a connecting portion 610 and a mounting portion 620 arranged perpendicular to each other, the connecting portion 610 is connected to the inner surface of the touch panel 100 by bonding, and the connecting device is connected to the mounting bracket 600 through the mounting portion 620.

In an embodiment of the present application, as shown in FIG. 5 , the mounting bracket 600 is L-shaped, and its connecting portion 610 is arranged in a direction away from the connecting device. Under this structure, the surface of the mounting portion 620 facing the connecting device has more space for connecting with the connecting device, which can reduce the size of the mounting bracket 600, thereby saving cost and reducing weight.

In another embodiment of the present application, as shown in FIG. 6 , the mounting bracket 600 is also L-shaped, and its connecting portion 610 is arranged toward the connecting device, and the end of the connecting portion 610 toward the device housing 200 protrudes relative to the touch panel 100. The contact panel 100 is damaged due to an impact on the device housing 200 , and the production and replacement costs of the installation bracket 600 are much lower than the production and replacement costs of the contact panel 100 , thereby reducing the maintenance cost of the equipment.

In the further preferred technical solution of the vibration feedback device based on the spring and damping structure described in the above specific embodiment, as shown in FIG. 3 , the damping device 500 can also be connected to the contact panel 100 and not connected to the device housing 200, and the damping device 500 is installed in this way. When the contact panel 100 is driven by the actuator 300 to move toward the device housing 200, the damping device 500 is compressed, absorbing vibration energy so that it is transmitted to the device housing 200 The vibration of the touch panel 100 is reduced, and when the touch panel 100 moves in the opposite direction, the touch panel 100 is separated from the damping device 500, so that the damping device 500 will not affect the movement of the touch panel 100 in this direction, the vibration amplitude of the touch panel 100 in this direction is larger, and the vibration feedback effect is better and more obvious.

The above scheme of connecting the damping device 500 with the touch panel 100 and only abutting with the device housing 200 reduces the transmission of vibration to the device housing 200 to a certain extent, so that the vibration can be fed back to the operator more strongly, but in the process of moving away from the device housing 200, the damping device 500 moves together with the touch panel 100. In this case, the damping device 500 as the load of the actuator 300 will cause the actuator 300 0 energy consumption increases, and under the same energy consumption situation, the vibration amplitude of the touch panel 100 will be affected.

Based on the above, as shown in FIG. 4 , the present application also provides a further preferred embodiment. In this specific embodiment, the damping device 500 is connected to the device housing 200 and only contacts the touch panel 100. The damping device 500 is installed in this way. When the touch panel 100 moves toward the device housing 200 under the drive of the actuator 300, the movement process of the damping device 500 and the spring device 400 is the same as the above-mentioned connection between the damping device 500 and the touch panel 10. 0 is connected to the device housing 200 but not connected to each other, but when it wants to move away from the device housing 200, the damping device 500 is still connected to the device housing 200. As the touch panel 100 moves away from the damping device 500, when the damping device 500 is fully recovered from the compression deformation, the contact panel 100 continues to move and will not drive the damping device 500. Therefore, the actuator 300 only needs to drive the touch panel 100 to vibrate, and its energy consumption will be less than the above scheme.

In the above scheme, the thickness of the damping device 500 in the static state is the same as the distance between the surface of the device housing 200 and the contact panel 100 connected thereto. In this manner, when the damping device 500 is connected to the touch panel 100, a gap is formed between it and the device housing 200. The setting of the gap can prevent the damping device 500 from absorbing vibration energy in a short period of time after the operator touches and operates the touch panel 100, thereby making the initial vibration of the touch obvious, so that the operator can obtain a more sensitive touch feedback experience. When the touch panel 100 moves in this direction for a certain distance, the damping device 500 starts to work and begins to reduce the vibration transmitted to the device housing 200. energy.

Likewise, when the damping device 500 is connected to the device casing 200 , a gap is formed between it and the contact panel 100 .

Specifically, the damping device 500 in this solution may be a material or device capable of absorbing vibrations such as silica gel, foam or a damper.

In the vibration feedback device based on the spring and damping structure described in this solution, the connecting device can be one or more. When there is one connecting device, it is arranged concentrically with the geometric center of the touch panel 100. When there are multiple connecting devices, multiple connecting devices are evenly arranged around the geometric centerline of the touch panel 100.

In this solution, since the connecting device is used to support the touch panel 100 and fix the touch panel 100 on the device housing 200 through it, the balance of the touch panel 100 is mainly considered for its uniform arrangement. Affected by the shape and size of the touch panel 100, the connecting device is not limited to multiple. When the first direction is the pressing direction of the touch panel 100, and when the balance of the touch panel 100 can be maintained, only one connecting device including the spring device 400 and the damping device 500 can be provided. .

In the above scheme, the spring device 400 and the damper device 500 are arranged adjacently, that is, each spring device 400 is provided with a damper device 500 near it, and the two cooperate to realize the design of the present application, but the relative position of the spring device 400 and the damper device 500 is not limited to the above, and other arrangements can be used in other embodiments. For example, as shown in FIGS. Among them, both the spring device 400 and the damping device 500 have a columnar structure, the outer dimensions of the damping device 500 are smaller than the outer dimensions of the spring device 400, the spring device 400 is sleeved outside the damping device 500, and the spring device 400 and the damping device 500 are arranged coaxially.

In this solution, the nesting arrangement of the spring device 400 and the damping device 500 can make full use of the space, so that there is more space in the device housing 200 to install other required components.

As a specific embodiment of the present application, the actuator 300 is one, and is arranged at the geometric center of the touch panel 100 , and the purpose of setting the actuator 300 at the geometric center of the touch panel 100 is also to ensure the balance of the touch panel 100 .

In other embodiments of the present application, there may be multiple actuators 300 , and multiple actuators 300 are evenly arranged around the geometric centerline of the touch panel 100 .

For example, referring to FIG. 8 , there are three actuators 300 in this specific embodiment, and the three actuators 300 are arranged side by side on the touch panel 100 , wherein the middle actuator 300 is arranged at the geometric center of the touch panel 100 , and the other two actuators 300 are arranged symmetrically with respect to the middle actuator 300 .

In the above scheme of setting up multiple actuators 300, all actuators 300 can work simultaneously or only part of the actuators 300 can work in one vibration feedback. When two or more actuators 300 work at the same time, it is necessary to control the vibration direction of the actuators 300 to be the same.

The following takes the touch panel 100 as a rectangle as an example to illustrate the number and layout of the connecting devices. Those skilled in the art can understand that the touch panel 100 is a rectangular structure and does not serve as a limitation to the present application. Under the design concept of this scheme, those skilled in the art can select the shape of the touch panel 100 according to actual needs.

As shown in FIG. 9 , in one embodiment of the present application, the connecting device is one. Under this structure, in order to ensure balance, it preferably adopts a scheme in which the spring device 400 and the damping device 500 are sleeved, and the spring device 400, the damping device 500 and the geometric center of the contact panel 100 are arranged concentrically. As shown in FIG. 0 is sleeved on the outside of the damping device 500.

As shown in FIG. 10 , in another specific embodiment using a connecting device, the geometric center of the spring device 400 , the damping device 500 and the contact panel 100 are also arranged concentrically, but in this solution, the damping device 500 is sleeved outside the spring device 400 .

In this solution, in addition to the support balance of the connecting device to the touch panel 100, it is also necessary to consider the influence of the actuator 300 on the balance of the touch panel 100. In the embodiment where the above two connecting devices are one, in order to ensure the balance of the touch panel 100, multiple actuators 300 need to be used, and the multiple actuators 300 are evenly arranged around the connecting device.

It should be pointed out that the connecting device is not limited to the setting method in which one spring device 400 corresponds to one damping device 500, and it can also adopt a structure in which one damping device 500 is provided and a plurality of spring devices 400 are arranged as a connecting device, or a structure in which one spring device 400 is provided and a plurality of damping devices 500 are arranged as a connecting device can be adopted.

Specifically, as shown in FIG. 11 , in yet another specific embodiment of the present application, a connecting device is adopted, and the connecting device includes a damping device 500 and four spring devices 400 evenly distributed on the circumference of the damping device 500 . The axis where the line connecting the geometric center of 0 is located is set symmetrically.

As shown in Figure 12, in another specific embodiment of the present application, a connecting device is adopted, and the connecting device includes a spring device 400 and four damping devices 500 uniformly distributed around the spring device 400. Also in order to ensure the balance of the support of the connecting device to the touch panel 100, the spring device 400 is coaxially arranged with the central axis of the touch panel 100 in this solution, and the four damping devices 500 are connected to the geometric center of the spring device 400 and the geometric center of the touch panel 100. The axis is set symmetrically.

It should be pointed out that the connecting device in this solution is not limited to the technical solution in which only one spring device 400 corresponds to multiple damping devices 500 or only one damping device 500 corresponds to multiple spring devices 400. In other embodiments, the connecting device may also include two or more spring devices 400 and two or more damping devices 500.

Moreover, the number of connection devices is not limited to only one, and in other embodiments, multiple connection devices may be provided between the touch panel 100 and the device housing 200 for connection and support.

As shown in FIGS. 13 and 14 , in other embodiments of the present application, there may be two connecting devices, each of which includes a spring device 400 and a damping device 500 , and the two connecting devices are arranged symmetrically with respect to the center line of the touch panel 100 .

As shown in Figures 15 and 16, in other embodiments of the present application, there may be three connecting devices, each of which includes a spring device 400 and a damping device 500, wherein one of the connecting devices includes a spring device 400 and a damping device 500, and the lines between the three connecting devices form an isosceles triangle or an equilateral triangle, wherein one of the connecting devices is located on a symmetrical center line of the touch panel 100, and the other two connecting devices are arranged symmetrically with respect to the symmetrical center line.

As shown in Figures 17 and 18, in other embodiments of the present application, there may be four connecting devices. The four connecting devices include a spring device 400 and a damping device 500. The four connecting devices are respectively arranged at the four corners of the contact panel 100. The installation directions of the four connecting devices should be ensured to be arranged symmetrically in pairs.

Preferably, when there are four connecting devices, each connecting device is arranged on a diagonal of the touch panel 100 in a rectangular structure.

It can be understood that when there are three or four connecting devices, an arrangement scheme in which all connecting devices are located on the same straight line may also be adopted.

For example, in the manner of arranging three connecting devices, preferably one of the connecting devices can be arranged at the geometric center of the touch panel 100 , and the other two connecting devices can be arranged at equal distances from the connecting device in the middle.

For another example, in the manner that four connecting devices are provided and the four connecting devices are located on the same straight line, it is preferable that the straight line where the four connecting devices are located is parallel to a symmetrical axis of the touch panel.

In this solution, the damping device 500 is used to absorb the transmission of vibration energy to the device housing 200. It can be understood that the number of damping devices 500 is not necessarily as high as possible. The number of damping devices 500 needs to be sufficient to absorb vibration energy and be compressed, so that the touch panel 100 has a certain amplitude space when moving in the direction of the damping device, so that the spring device can accumulate energy, so that when it vibrates in the opposite direction, a larger vibration amplitude can be generated, and the user receives stronger vibration feedback.

The vibration feedback device based on the spring and damping structure described in the embodiment of the present application further includes a contact sensor for detecting a touch signal received by the touch panel 100 and driving the actuator 300 to vibrate according to the touch signal to form vibration feedback.

Specifically, the touch sensor sends different control commands to the actuator 300 according to the intensity of the detected touch signal, so that the actuator 300 performs vibration feedback of different intensities. In one embodiment of the present application, the touch sensor can be a pressure sensor. When the operator's finger presses the touch panel 100, the pressure sensor detects the pressure signal, and the actuator 300 is controlled to vibrate through the control circuit.

In other preferred embodiments of the present application, the touch sensor can also be a capacitive sensor or an infrared sensor, which determines the touch signal strength by detecting the size of the touch area of the touch panel 100 subjected to the touch operation. 19 and 20, take finger operation touch panel 100 as an example, when the operator exerts less pressure on touch panel 100, the contact area of finger and touch panel 100 is smaller, referring to Figure 19; Small, from yes to no), when the change of the contact area D crosses the set threshold, the working state of the actuator 300 changes, forming different degrees of vibration feedback or stopping the vibration feedback according to the preset.

At the same time, an embodiment of the present application also provides a touch device, which has the above-mentioned vibration feedback device based on a spring and damping structure, and the vibration feedback device based on a spring and damping structure is arranged on a touch panel, a touch display screen or a touch button of the touch device.

The touch device described in this scenario can be almost any type of device that may require haptic feedback, such as a smart phone, digital music player, digital camera, video game device, laptop or tablet computer, large educational or business tablet, and the like. The touch device may be a button, switch, or other input/output member operably connected to the housing of the touch device.
