[0029] The driving device of the utility model adopts only one power mechanism, and drives the linkage component through the driving component, and the linkage component is connected to the first transmission mechanism and the second transmission mechanism respectively, so as to drive the first transmission mechanism and the second transmission mechanism to move synchronously. The first transmission mechanism and the second transmission mechanism can move with two movable support frames respectively, so as to realize the synchronous movement of the movable support frames. The utility model not only reduces the number of power mechanisms, reduces the installation and manufacturing costs, and saves energy, but also can realize the synchronous movement of multiple support frames and improve the adjustment accuracy.

[0030] Preferably, the first transmission mechanism 100 and the second transmission mechanism 200 both include a support and guide assembly for supporting and guiding the transmission assembly, and the transmission assembly and the support and guide assembly are movably connected.

There are two drive sleeves 6, which are respectively arranged at both ends of the drive rod 5 and are respectively connected to the first transmission mechanism 100 and the second transmission mechanism 200.

[0035] The output shaft of the first power mechanism is provided with a first driving wheel to drive the first driving wheel to rotate. The driving belt passes around the first driving wheel and the first driven wheel, the first driving wheel rotates, and drives the first driven wheel to rotate through the driving belt, so that the driving rod rotates. The screw threads of the two driving sleeves are in opposite directions. Therefore, when the first power mechanism drives the driving rod to rotate, the two driving sleeves move synchronously in opposite directions, so that the distance between the two gradually increases, so that the first transmission mechanism and the second transmission mechanism move synchronously and the distance gradually increases, so that the two movable support frames connected to the first transmission mechanism and the second transmission mechanism respectively move inward synchronously; when the first power mechanism drives the driving rod to rotate in opposite directions, the two driving sleeves move synchronously relative to each other, so that the distance between the two gradually decreases, so that the first transmission mechanism and the second transmission mechanism move synchronously and the distance gradually decreases, so that the two movable support frames connected to the first transmission mechanism and the second transmission mechanism respectively move outward synchronously, thereby realizing the movement of the two movable support frames, and then realizing the bending deformation of the LED display.

[0036] The first embodiment of the utility model adopts only one first power mechanism, which drives the first transmission mechanism and the second transmission mechanism to move synchronously through the cooperation of the driving rod and the driving sleeve, which not only reduces the setting of the power mechanism, but also effectively ensures the synchronous movement of the first transmission mechanism and the second transmission mechanism, thereby improving the adjustment accuracy.

Specifically, the number of the second driven wheels is at least two, which are respectively provided on the first transmission mechanism and the second transmission mechanism, so that the linkage belt can extend to the first transmission mechanism and the second transmission mechanism respectively, thereby driving the first transmission mechanism and the second transmission mechanism to move. More specifically, the second adapter of the first transmission mechanism and the second adapter of the second transmission mechanism are respectively provided on opposite sides of the linkage belt. When the second power mechanism drives the linkage belt to rotate, it can push the two second adapters to move synchronously relative to each other, so that the first transmission mechanism and the second transmission mechanism move synchronously and the distance gradually decreases, so that the two movable support frames respectively connected to the first transmission mechanism and the second transmission mechanism move synchronously outward; when the second power mechanism drives the linkage belt to rotate in the opposite direction, it can push the two second adapters to move synchronously back to back, so that the first transmission mechanism and the second transmission mechanism move synchronously and the distance gradually increases, so that the two movable support frames respectively connected to the first transmission mechanism and the second transmission mechanism move synchronously inward, thereby realizing the movement of the two movable support frames, and then realizing the bending and deformation of the LED display.

[0041] The second embodiment of the utility model adopts only one second power mechanism, which drives the first transmission mechanism and the second transmission mechanism to move synchronously through the cooperation of the linkage belt and the second driven wheel, which not only reduces the setting of the power mechanism, but also effectively ensures the synchronous movement of the first transmission mechanism and the second transmission mechanism, thereby improving the adjustment accuracy.

The setting of the locking piece can play a positioning role for the first transmission mechanism and the second transmission mechanism, and prevent the first transmission mechanism and the second transmission mechanism from sliding along the second guide rod under the action of external force, causing the change of the bending angle of the movable support frame and affecting the adjustment accuracy. Rotate the locking piece in the opposite direction to separate the locking piece and the second guide rod, and the second adapter is slidably connected to the second guide rod again.
