The side protection shell 1 31 and the side protection shell 2 32 are correspondingly arranged on the rear side of the display screen 2, and the rear sides of the side protection shell 1 31 and the side protection shell 2 32 are connected with the push assembly 33 and the sliding assembly 34. A space is reserved between the side protection shell 1 31 and the side protection shell 2 32 for the positioning assembly 1 338 and the positioning assembly 2 339 of the push assembly 33 to pass through and connect with the back of the display screen 2. The push assembly 33 and the sliding assembly 34 are installed on the fixed stand 1;

[0042] It should be noted that the side protective shell 1 31 and the side protective shell 2 32 are symmetrically arranged on the left and right, with a cavity provided on the inner side and a sealing strip provided at the inner edge of the cavity. The cavity is used for retracting and unfolding the display screen 2. At the same time, the sealing strip can increase the sealing between the display screen 2, reduce the entry of water vapor, and increase moisture resistance.

[0043] like Figure 5-6 As shown, in this embodiment, the pushing assembly 33 includes an outer ring seat 331, an inner ring plate 332, a bottom connecting plate 333, a swing arm 1 334, a swing arm 2 335, a V-shaped groove 1 336, a V-shaped groove 2 337, a positioning assembly 1 338, a positioning assembly 2 339 and a motor 1 3310. The inner ring plate 332 is provided inside the outer ring seat 331, and the bottom connecting plate 333 is provided on the back. The middle parts of the outer ring seat 331 and the bottom connecting plate 333 are connected to the output shaft of the motor 1 3310 installed on the back of the fixed stand 1, and the two ends of the bottom connecting plate 333 are respectively rotatably connected to one end of the swing arm 1 334 and the swing arm 2 335, and the other ends of the swing arm 1 334 and the swing arm 2 335 are respectively rotatably connected to the rear middle parts of the side protective shell 1 31 and the side protective shell 2 32. The outer ring seat 331 , the inner ring plate 332 is respectively provided with a V-groove 1 336 and a V-groove 2 337, and the V-groove 1 336 and the V-groove 2 337 are arranged opposite to each other, and the outer ring seat 331 and the inner ring plate 332 are respectively provided with a positioning component 1 338 and a positioning component 2 339, the positioning component 1 338 is arranged opposite to the V-groove 1 336 on the outer ring seat 331, and the positioning component 2 339 is arranged opposite to the V-groove 2 337 on the inner ring plate 332, after the V-groove 1 336 corresponds to the positioning component 1 338, and at the same time the V-groove 2 337 corresponds to the positioning component 2 339, the display screen 2 can be moved backward, and the positioning component 1 338 and the positioning component 2 339 are installed on the fixed stand 1, and the front ends are connected to the rear end of the display screen 2;

[0044] Among them, the positioning component 1 338 and the positioning component 2 339 have the same structure, and the two are symmetrically arranged up and down, which can be better used to connect the display screen 2 so that it can move forward and backward stably;

[0045] Specifically, when it is necessary to perform side protection on the display screen 2, after the motor 1 3310 is turned on, the outer ring seat 331, the inner ring plate 332 and the bottom connecting plate 333 are driven to rotate. After the bottom connecting plate 333 rotates, the swing arms 1 334 and 335 at both ends can be synchronously driven, and the swing arms 1 334 and 335 synchronously push the side protective shell 1 31 and the side protective shell 2 32. When the side protective shell 1 31 and the side protective shell 2 32 are synchronously pushed outward, the rotation of the outer ring seat 331 and the inner ring plate 332 can move the V-shaped groove 1 336 and the V-shaped groove 2 337 to the corresponding positions of the positioning columns 3383 of the positioning components 1 338 and the positioning components 2 339, and the positioning columns 3383 of the positioning components 1 338 and the positioning components 2 339 enter the V-shaped groove 1 336 and the V-shaped groove 2 337, so that the display screen 2 The side protective shell 31 and the side protective shell 2 move backward in parallel with each other, and the side protective shell 31 and the side protective shell 2 are pushed by the swing arm 1 334 and the swing arm 2 335 to move inward to wrap the side of the display screen 2 for protection, thereby preventing the display screen 2 from getting wet; when the side protection device 3 needs to be removed from the display screen 2, the motor 1 3310 is started to rotate in the opposite direction, so that the side protective shell 31 and the side protective shell 2 32 are separated from the wrapping of the side of the display screen 2, and then the positioning columns 3383 of the positioning components 1 338 and the positioning components 2 339 are moved out from the V-groove 1 336 and the V-groove 2 337, so that the display screen 2 can move forward, and the side protective shell 31 and the side protective shell 2 32 are retracted to the rear side of the display screen 2, so that the side protective shell 31 and the side protective shell 2 32 do not affect the use of the display screen 2.

[0046] like Figure 5As shown, in this embodiment, the sliding assembly 34 includes a slide bar seat 1 341, a slide bar seat 2 342, a slide bar 1 343, a slide bar 2 344, a slide bar 345 and a slide bar 4 346. The slide bar seat 1 341 and the slide bar seat 2 342 are symmetrically arranged up and down and installed on the fixed stand 1, and the pushing assembly 33 is located between the slide bar seat 1 341 and the slide bar seat 2 342. The slide bar 1 343 and the slide bar 345 are arranged inside the slide bar seat 1 341. The slide bar 1 343 and the slide bar 345 are interlocked with each other for sliding cooperation. The slide bar seat 2 342 is provided with a slide bar 2 344 and a slide bar 4 346. The slide bar 2 344 and the slide bar 4 346 are interlocked with each other for sliding cooperation. Yes, the slide bar 1 343, the slide bar 2 344, the slide bar 345 and the slide bar 4 346 are all L-shaped, so that the slide bar 1 343 and the slide bar 345 can be interlocked with each other, and the slide bar 1 343 and the slide bar 345 can be interlocked with each other and then slide together, the slide bar 1 343 and the slide bar 2 344 are respectively connected to the upper and lower ends of the back of the side protective shell 1 31, and the slide bar 345 and the slide bar 4 346 are connected to the upper and lower ends of the back of the side protective shell 2 32. Through the sliding cooperation of the slide bar 1 343 and the slide bar 2 344, the side protective shell 1 31 can be horizontally moved to prevent deviation, and the sliding cooperation of the slide bar 345 and the slide bar 4 346 can make the side protective shell 2 32 move horizontally to prevent deviation;

[0047] Specifically, when the side protective shell 1 31 and the side protective shell 2 32 move to the sides, the slide bar 1 343 and the slide bar 345 slide and cooperate in the slide bar seat 1 341, and at the same time, the slide bar 2 344 and the slide bar 4 346 slide and cooperate in the slide bar seat 2 342, and the slide bar 1 343 and the slide bar 2 344 synchronously drive the side protective shell 1 31 to move horizontally to prevent deviation, and at the same time, the slide bar 345 and the slide bar 4 346 synchronously drive the side protective shell 2 32 to move horizontally to prevent deviation.

The rear end of the positioning column 3383 cooperates with the V-shaped groove 1 336. The positioning column 3383 is located between the supporting plate 3382 and the vertical plate body of the L-shaped fixing plate 3381 and is sleeved with a spring 3384. One end of the spring 3384 is connected to the vertical plate body of the L-shaped fixing plate 3381, and the other end is connected to the convex ring provided in the middle of the positioning column 3383.

[0049] Specifically, the spring 3384 can drive the positioning column 3383 to move backward, and the positioning column 3383 is restricted by the support plate 3382. After the positioning column 3383 enters the V-shaped groove 336, the positioning column 3383 drives the display screen 2 to move backward. After the positioning column 3383 leaves the V-shaped groove 336, it will compress the spring 3384 and push the display screen 2 forward.
