[0030] In addition, refer to Figure 1 and Figure 2In this embodiment, the driving mechanism includes a fixed box 4, a rotating shaft 41, a locking assembly, a driving motor 42, a driving gear 43 and a driven gear 44. Among them, a plurality of fixed blocks are installed on the outside of the fixed box 4, and the plurality of fixed blocks are fixedly installed inside the carport by screws to achieve a stable installation of the fixed box 4; the rotating shaft 41 is rotatably installed on one side of the fixed box 4, and one end of the rotating shaft 41 extending outside the fixed box 4 is fixedly connected to the connecting bracket 1 through the locking assembly.

[0031] Specifically, the locking assembly includes a locking screw 5, a locking block 11, a locking ring 51 and a locking nut 6. One end of the locking screw 5 is fixedly connected to the end of the rotating shaft 41 extending outside the fixed box 4, and the diameter of the locking screw 5 is smaller than the diameter of the rotating shaft 41; the locking block 11 is fixedly installed on one side of the connecting bracket 1, the locking block 11 and the connecting bracket 1 are arranged perpendicular to each other, and a locking hole matching the locking screw 5 is opened on the locking block 11, and the locking hole is provided so that the locking block 11 can be slidably sleeved on the locking screw 5.

[0032] Meanwhile, a plurality of locking rings 51 are provided, and the plurality of locking rings 51 cooperate with the locking screw 5, so that the locking rings 51 are slidably sleeved on the locking screw 5; and the apertures of the locking rings 51 are smaller than the diameter of the rotating shaft 41, so that the locking rings 51 are blocked by the shaft end of the rotating shaft 41. The locking block 11 is located between the locking rings 51, so that the locking rings 51 and the locking block 11 abut against each other.

[0037] The implementation principle of the electric flip fixing device for a vehicle-mounted ceiling screen in the embodiment of the present application is as follows:

[0038] When it is necessary to flip and unfold the vehicle-mounted ceiling screen, the electronic control board simultaneously outputs signals to the two drive motors 42, and the output ends of the two drive motors 42 respectively drive the driving gear 43 to rotate clockwise, and the driving gear 43 drives the driven gear 44 to rotate clockwise, and the driven gear 44 drives the rotating shaft 41 to rotate, so that the rotating shaft 41 drives the connecting bracket 1 to rotate through the locking assembly, and the two connecting brackets 1 simultaneously drive the vehicle-mounted ceiling screen on the swing bracket 2 to slowly open, and finally the closing signal is output to the drive motor 42 through the electronic control board, and the drive motor 42 slowly closes, thereby completing the process of flipping and unfolding the vehicle-mounted ceiling screen.

[0039] When it is necessary to flip and close the vehicle-mounted ceiling screen, a signal is simultaneously output to the two drive motors 42 through the electronic control board, and the output ends of the two drive motors 42 respectively drive the driving gear 43 to rotate counterclockwise, and the driving gear 43 drives the driven gear 44 to rotate counterclockwise, and the driven gear 44 drives the rotating shaft 41 to rotate, so that the rotating shaft 41 drives the connecting bracket 1 to rotate through the locking assembly, and the two connecting brackets 1 simultaneously drive the vehicle-mounted ceiling screen on the swing bracket 2 to slowly close, and finally the closing signal is output to the drive motor 42 through the electronic control board, and the drive motor 42 slowly closes, thereby completing the process of flipping and closing the vehicle-mounted ceiling screen.
