[0023] The movable shaft 6 and the gear 7 are driven to rotate by the driving assembly 9, and the tooth groove 8 is used to drive the side screen frame 2 to move in the movable frame 4. Then, the movable frame 4 is deflected with the cooperation of the deflection assembly 5, so that the side screen frame 2 can be flipped backward from the flush position on both sides of the main screen frame 1, so that the side screen frame 2 can be stored in the storage groove 3 separately, thereby avoiding the large-angle flipping of the side screen frame 2, which is not only inconvenient to operate, but also occupies a large space, which is not conducive to the installation and use of the display screen.

[0024] The deflection assembly 5 includes a first rotating shaft 51 that rotates inside the main screen frame 1 through a bearing, two groups of support plates 52 are fixed to the outside of the first rotating shaft 51, the top and bottom of the movable frame 4 are rotatably connected to the second rotating shaft 53 through bearings, the second rotating shaft 53 is fixedly connected to the support plate 52, and a deflection motor 54 fixed to one end of the first rotating shaft 51 is fixed to the top of the movable frame 4. The first rotating shaft 51 is driven to rotate by the deflection motor 54, and then the first rotating shaft 51 adjusts the position of the movable frame 4 through the support plate 52, so as to facilitate the backward displacement of the side screen frame 2 flush with the front of the main screen frame 1, thereby achieving the purpose of independently storing the side screen frames 2 on both sides.

[0029] Extension grooves connected to the storage grooves 3 are opened on both sides of the main screen frame 1, and the support plate 52 is located in the extension grooves. The setting of the extension grooves facilitates the storage of the support plate 52 and reduces the space occupied by the support plate 52 and the first rotating shaft 51.

[0030] During specific use, when it is necessary to fold and store the side screen frames 2 on both sides, first start the drive motor 91, the drive motor 91 drives the worm 92 to rotate, and then the worm 92 drives the movable shaft 6 to rotate through the worm gear 93, and the movable shaft 6 drives the gear 7 to rotate, and the tooth groove 8 is used to translate the side screen frame 2 outward, so that the positioning column 14 is moved out of the positioning hole 13, and then the deflection motor 54 drives the first rotating shaft 51 to rotate, and the support plate 52 is used to make the movable frame 4 flip backward, and then in this process, the rotating motor 12 calibrates the orientation of the movable frame 4 through the second rotating shaft 53, so that the movable frame 4 and the side screen frame 2 remain parallel to the main screen frame 1, and then the drive motor 91 drives the gear 7 to rotate, so that the side screen frame 2 is stored in the storage groove 3, and the folding and storage is completed.
