[0029] In some embodiments, according to Figure 3 As shown, the transmission assembly includes a rotating shaft 7 rotatably connected to one side of the transmission plate 3. The rotating shaft 7 passes through the transmission plate 3 and extends to the other side of the transmission plate 3. A stepper motor 8 is fixedly provided on the other side of the transmission plate 3. The output end of the stepper motor 8 is fixedly connected to the rotating shaft 7. A gear 9 is provided on one side of the transmission plate 3. The gear 9 is fixedly connected to the rotating shaft 7.

[0030] In some embodiments, according to Figure 3 As shown, there are two racks 10 meshing on the outer side of the gear 9. There are slides 11 on both sides of the gear 9. The two slides 11 are slidably connected to the two racks 10 respectively. The slides 11 are fixedly connected to the transmission plate 3. One end of each rack 10 is fixedly provided with a drive plate 12. The drive plate 12 is fixedly connected to the drive frame 4.

[0031] In some embodiments, according to Figure 2 , 3 As shown, a central block 13 is fixedly provided at the top and bottom of the transmission plate 3. Telescopic rods 14 are fixedly provided on both sides of the central block 13. A connecting block 15 is fixedly provided at one end of the telescopic rod 14. The connecting block 15 is fixedly connected to the drive frame 4. When the drive frame 4 moves, it drives the connecting block 15 to move and the telescopic rod 14 to extend and retract. The telescopic rod 14 and the connecting block 15 can provide support for the drive frame 4.

[0032] In some embodiments, according to Figure 2 , 4 As shown, the support assembly includes multiple rubber support plates 16 fixed to one side of the flexible display screen 1. Each of the multiple rubber support plates 16 has a support rod 17 fixed to one side. Two of the support rods 17 are rotatably connected to the drive frame 4. Two first connecting plates 18 are provided on one side of the flexible display screen 1. Two first electric push rods 19 are hinged to one side of each of the two first connecting plates 18. The rubber support plates 16 can connect the flexible display screen 1 and the support rods 17, providing cushioning and limiting support for the flexible display screen 1 when folded.

[0033] In some embodiments, according to Figure 2 , 4 As shown, both first electric push rods 19 are hinged to the drive plate 12, and both first connecting plates 18 are provided with second connecting plates 20 on their front sides. The second connecting plates 20 are fixedly connected to the flexible display screen 1.

[0034] In some embodiments, according to Figure 1 , 3 As shown, two second electric push rods 21 are hinged to one side of the second connecting plate 20. Both second electric push rods 21 are hinged to the movable plate 5. The first electric push rod 19 and the second electric push rod 21 provide support for the flexible display screen 1 while driving it to fold and extend.

[0035] The working principle of this utility model is as follows: (refer to the appendix of the instruction manual) Figure 1-4 As shown, the flexible display screen 1 used in this utility model is a 55-inch large flexible display screen 1. When the flexible display screen 1 needs to be folded, the stepper motor 8 is started to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the gear 9 to rotate, causing the two racks 10 to move closer to the center of the gear 9, thereby causing the driving plate 12 and the driving frame 4 to move closer to the gear 9. The driving frame 4 then drives the movable plate 5 to move closer to the gear 9, thereby causing the two sides of the flexible display screen 1 to fold closer to the center.

[0036] While the frame 4 moves, the connecting block 15 moves toward the center block 13, thereby compressing the telescopic rod 14. At the same time, the first electric push rod 19 and the second electric push rod 21 are activated to pull the first connecting plate 18 and the second connecting plate 20 closer, thereby driving the flexible display screen 1 to squeeze the rubber support plate 16 to its maximum size along the support rod 17 and fold it, so that the flexible display screen 1 is folded smoothly.

[0037] When it is necessary to unfold the flexible display screen 1, start the stepper motor 8 to reverse, and at the same time start the first electric push rod 19 and the second electric push rod 21 to extend, so that each component performs the above steps in reverse order, and the flexible display screen 1 can be fully unfolded.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
