The body 10 includes a bottom end 11, a top end 12 and a side wall 13 supporting the bottom end 11 and the top end 12 to maintain the relative positions, the bottom end 11, the top end 12 and the side wall 13 enclose to form an accommodating space 101, the bottom end 11 and the top end 12 are correspondingly provided with two accommodating portions 14, one of the accommodating portions 14 may be an accommodating groove or a through hole arranged on the bottom end 11, and the other accommodating portion 14 may be an accommodating groove or a through hole arranged on the top end 12. The bottom end 11 may be placed on a resting surface (which may be a floor, a table, a counter, etc.) or may be secured to a mounting surface during use. In the case where the bottom end 11 is used while being placed on a resting surface, in order to avoid toppling, the projected area of the top end 12 toward the bottom end 11 is smaller than the area of a first end face of the bottom end 11, which is the surface of the bottom end 11 toward the top end 12; alternatively, the bottom end 11 weighs more than the top end 12; to provide a larger counterweight to ensure stability of the entire base 100.
The rotating shaft assembly 20 is disposed in the accommodating space 101 and can rotate clockwise or counterclockwise relative to the body 10. Specifically, the rotating shaft assembly 20 is movably disposed in the accommodating space 101 through the two accommodating portions 14. The rotating shaft assembly 20 includes two bearing parts 21 disposed oppositely, the two bearing parts 21 are disposed on the two accommodating parts 14 of the body 10 respectively and can rotate clockwise or counterclockwise relative to the accommodating parts 14, and the bearing surfaces of the two bearing parts 21 opposite to each other are provided with fixing parts 22 for fixing specific positions of the flexible screen 200 respectively, so that the flexible screen 200 is wound based on the fixing parts 22.
In order to wind the flexible screen 200 and facilitate unfolding the flexible screen 200, the fixing portion 22 includes two rotating shafts symmetrically disposed with respect to a center line of the body 10, as shown in fig. 1c, the two rotating shafts are a first rotating shaft 221 and a second rotating shaft 222, respectively, as shown in fig. 3 and 4, a space L not smaller than a thickness of the flexible screen 200 is provided between the two rotating shafts (i.e., the first rotating shaft 221 and the second rotating shaft 222), so that the flexible screen 200 can be wound by one of the rotating shafts and continuously wound by the other rotating shaft after passing through the space. In order to ensure that the flexible screen 200 is not damaged in winding, the part of the fixing part 22 for winding the flexible screen 200 adopts a smooth transition structure, and the two rotating shafts are provided with curved surfaces for winding the flexible screen, and the curvature radius of the curved surfaces is not less than the limit curling damage radius of the flexible screen. As shown in fig. 4, in an embodiment of the present disclosure, the cross sections of the two rotating shafts each include a linear portion and a curved portion connected to two ends of the linear portion, the curved portion includes three arc-shaped sections, the curvature radii of the three arc-shaped sections are R1, R2, and R3, respectively, none of R1, R2, and R3 is smaller than the limit curl damage radius of the flexible screen, the linear portion of the first rotating shaft 221 is opposite to the linear portion of the second rotating shaft 222, and an interval L not smaller than the thickness of the flexible screen is provided between the two linear portions, and the fixing portion 22 with this structure can ensure that the flexible screen 200 is wound. As shown in fig. 5, in another embodiment of the present disclosure, the cross sections of the two rotating shafts each include a linear portion and a curved portion connected to two ends of the linear portion, the curved portion includes two arc-shaped sections, the curvature radii of the two arc-shaped sections are R1 and R2, respectively, neither R1 nor R2 is smaller than the limit curl damage radius of the flexible screen, the linear portion of the first rotating shaft 221 is opposite to the linear portion of the second rotating shaft 222, and an interval L not smaller than the thickness of the flexible screen is provided between the two linear portions, and the fixing portion 22 of this structure can ensure that the flexible screen 200 is wound. In still another embodiment of the present disclosure, as shown in fig. 6, the cross-sectional shape of the first rotating shaft 221 and the cross-sectional shape of the second rotating shaft 222 are both ring-shaped, and there is a space L between the two ring-shaped, which is not less than the thickness of the flexible screen, and the fixing portion 22 of this structure can also ensure the flexible screen 200 to be wound.

In this way, the purpose of synchronous rotation of the first rotating shaft 221 and the second rotating shaft 222 can be achieved by only one driving member of the rotating shaft assembly 20, and the second rotating shaft 221 does not have the shaft body 2213, so that when the flexible screen 200 is unfolded, the display area of the flexible screen 200 is not shielded and the display effect is not affected (as shown in fig. 7). In an embodiment not shown, the second shaft 221 may also include a shaft body 2213 connecting the first end 2211 and the second end 2212, and it should be understood that the base 100 having both shafts 2213 is suitable for use without regard to the shaft body 2213 covering the unfolded flexible screen 200.
Referring again to fig. 1b, the base 100 further has a limiting structure 40, and the limiting structure 40 is used for limiting the extension or retraction of the element 200 to be wound. The position-limiting structure 40 may be disposed on the body 10, or may be disposed in the accommodating space 101, and a detailed arrangement of the position-limiting structure 40 will be described later with reference to the supporting assembly 30.
The two supporting components 30 are respectively disposed on two opposite sides of the body 10, and when the rotating shaft component 20 rotates clockwise or counterclockwise, the two supporting components 30 can extend or retract relative to the body 10 to support the flexible screen 200 in the unfolding state or enable the flexible screen 200 in the storage state. As shown in fig. 2, 3, 7 and 9, the free end of the flexible screen 200 is connected to the first portion of the sidewall 13, the first portion can be separated from the bottom end 11 or the top end 12 and extend in a direction perpendicular to the center line of the body to unfold the flexible screen 200 when the rotating shaft assembly 20 rotates, the first portion of the sidewall 13 forms the supporting assembly 30, in this case, the limiting structure 40 is a slot provided on the supporting assembly 30 for limiting the flexible screen 200 to extend or retract, and the slot is communicated with the accommodating space 101.
Further, the base 100 may further include a driving device (not shown) for driving the rotation of the spindle assembly 20 and the extension/retraction of the support assembly 30, and an electric control device (not shown) for controlling the operation of the driving device, wherein an activation signal of the driving device may be obtained by using a button, a sensor, or image recognition.

The driving device can also be arranged on the side wall 11 of the fixed part except the first part, the output shaft of the driving device is connected with the supporting component 30 to directly drive the supporting component 30, and meanwhile, the output shaft of the driving device drives the top end 12 or the bottom end 11 through the transmission mechanism to drive the rotating shaft component 20. It should be noted that the position of the driving device may be set reasonably according to specific situations, including but not limited to the above setting position, as long as it is ensured that the flexible screen 200 does not interfere with the flexible screen 200 when the flexible screen 200 is unfolded or stored. In addition, the rotation of the rotary shaft assembly 20 and the extension/retraction of the support assembly 30 may be driven by different driving means. Specifically, the rotating shaft assembly 20 is driven by a first driving device, the support assembly 30 is driven by a second driving device, the first driving device and the second driving device are respectively connected with an electric control device, and under the control of the electric control device, when the first driving device drives the rotating shaft assembly 20 to rotate clockwise, the second driving device drives the support assembly 30 to retract relative to the body; or, when the first driving device drives the rotating shaft assembly 20 to rotate counterclockwise, the second driving device drives the support assembly 30 to extend relative to the body. In this case, a first driving device may be disposed on the top end 12, and an output shaft of the first driving device is connected to the top end 12 to directly drive the top end 12 to drive the rotating shaft assembly 20; the first driving device can also be arranged on the bottom end 11, and an output shaft of the first driving device is connected with the bottom end 11 to directly drive the bottom end 11 to drive the rotating shaft assembly 20. A second driving means 30 is provided on the side wall 11 of the fixed portion excluding the first portion, and an output shaft of the second driving means is connected to the support member 30 to directly drive the support member 30. It should be noted that the position of the first driving device and the position of the second driving device may be set reasonably according to specific situations, including but not limited to the above setting positions, as long as it is ensured that the flexible screen 200 does not interfere with the flexible screen 200 when the flexible screen 200 is unfolded or stored.
As a modification of the electric driving manner, the rotation of the spindle assembly 20 and the extension/retraction of the support assembly 30 may also be manually driven.
As shown in fig. 8a and 8b, another embodiment of the support assembly 30 may be: has a first end 301 and a second end 302, the first end 301 is slidably disposed on the body 10 or the rotary shaft assembly 20, and the second end 302 is hinged at the free end of the flexible screen 200. An elastic expansion piece 35 is arranged between the first end 301 and the second end 302, the elastic expansion piece 35 can provide rigid support for the first end 301 and the second end 302 when being stretched and can remove the rigid support when being compressed, in this case, the limiting structure 40 is a slot which is arranged on the bottom end 11 and/or the top end 12 and is used for limiting the flexible screen 200 to be extended or retracted, and the slot is communicated with the accommodating space 101. Specifically, the support assembly 30 includes a first rod 31, a second rod 32 and a third rod 33, the first rod 31 is slidably disposed on the side wall 13 of the body 10, each of the second rod 32 and the third rod 33 has one end (the end corresponding to the first end 301) hinged to the first rod 31 and the other end (the end corresponding to the second end 302) hinged to the free end of the flexible screen 200, an elastic expansion member 35 is sleeved on the side wall 13, one end of the elastic expansion member 35 is disposed on the first rod 31, the other end can be disposed on the bottom end 11 or the top end 12, the elastic expansion member 35 is elongated along the side wall 13 when the second rod 32 and the third rod 33 extend relative to the body 10, and is restored to a normal length along the side wall 13 when the second rod 32 and the third rod 33 retract relative to the body 10. In an embodiment not shown, the side wall 13 may be provided with a receiving groove, and the first rod 31 and the elastic expansion member 35 are disposed in the receiving groove. It should be noted that the second rod 32 and the third rod 33 are not limited to the one-rod type shown in the drawings, but may be formed in a two-rod hinge type, and the number of the rod members of the support assembly 30 may be designed according to specific situations, including, but not limited to, the three-rod type shown in the drawings. In this case, the support assembly 30 does not require a driving device, and only the rotating shaft assembly 20 needs to be connected to the driving device. When the rotating shaft assembly 20 rotates anticlockwise, under the action of the tensile force of the elastic telescopic piece 35, the first rod 31 slides downwards, the second rod 32 and the third rod 33 both rotate anticlockwise relative to the first rod 31, and the support assembly 30 extends out relative to the body 10, so that the flexible screen 200 is unfolded; when the rotating shaft assembly 20 rotates clockwise, the fixing portion 22 winds the flexible screen 200, and the flexible screen 200 drives the second rod 32 and the third rod 33 to rotate clockwise relative to the first rod 31, so that the support assembly 30 retracts relative to the body 10.
