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 portion of the fixing portion 22 for winding the flexible screen 200 adopts a smooth transition structure, and both rotating shafts have curved surfaces for winding the flexible screen, and the curvature radius of the curved surfaces is not less than the limit winding 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 segments, the curvature radii of the three arc-shaped segments are R1, R2, R3, and no less than the limit curl breaking radius of the flexible screen for all of R1, R2, and R3, 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 less than the thickness of the flexible screen is provided between the two linear portions, and the fixing portion 22 of the 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 straight portion and a curved portion connected to two ends of the straight portion, the curved portion includes two arc-shaped sections, the curvature radii of the two arc-shaped sections are R1 and R2, R1 and R2 are not less than the maximum curl breaking radius of the flexible screen, the straight portion of the first rotating shaft 221 is opposite to the straight portion of the second rotating shaft 222, and a space L not less than the thickness of the flexible screen is provided between the two straight portions, and the fixing portion 22 of the 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.

Therefore, 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 to be wound 200. 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.

It should be noted that the position of the driving device may be set 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.

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, the first rod 31 slides downwards under the action of the tensile force of the elastic expansion piece 35, 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.
