DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a fixing structure of a cockpit ceiling screen includes a fixing frame, an inner wall of the fixing frame 1 is provided with a slide groove 2, and a positioning slider 201 is slidably installed inside the slide groove 2. The advantage of this arrangement is that the sliding support plate 202 can be limited by the arrangement of the positioning slider 201 so that it can move stably.

[0024] Furthermore, a sliding support plate 202 is provided at the front end of the positioning slider 201, and a threaded transmission rod 203 is provided on the lower end surface of the sliding support plate 202. The threaded transmission rod 203 and the sliding support plate 202 are spirally connected, and a driving motor 204 is provided at the front end of the threaded transmission rod 203. The advantage of this arrangement is that through the setting of the threaded transmission rod 203, the sliding support plate 202 can be controlled to move, so as to achieve the purpose of moving the ceiling screen and improve the viewing experience of passengers.

[0025] like Figure 3-Figure 4 As shown, a slide groove 23 is provided on the surface of the sliding support plate 202, and a tension spring 301 is provided inside the slide groove 23. A sliding block 302 is fixedly installed at the front end of the tension spring 301, and the sliding block 302 and the slide groove 23 are slidably connected. The advantage of this arrangement is that through the arrangement of the tension spring 301, the clamping plate 304 can be quickly driven to position and clamp the screen, thereby speeding up the installation of the screen and facilitating later maintenance and replacement.

[0026] Furthermore, a damping shaft 303 is rotated at the front end of the sliding block 302, and a clamp 304 is provided at the front end of the damping shaft 303. A decompression strip 305 is installed on the inner wall surface of the clamp 304, and the shape of the decompression strip 305 is L-shaped. The advantage of this arrangement is that the pressure when the clamp 304 clamps the screen can be reduced through the arrangement of the decompression strip 305.

[0027] Furthermore, a limited telescopic rod 402 is provided on the bottom surface of the fixing frame 1, and a compression spring 403 is provided on the surface of the limited telescopic rod 402. The advantage of this arrangement is that the downward pressure brought by the compression buffer protection plate 4 can be buffered by the arrangement of the compression spring 403.

[0028] Furthermore, a support base 401 is installed on the upper end of the compression spring 403, and a protective plate 4 is installed on the upper end of the support base 401. The advantage of this arrangement is that, through the arrangement of the protective plate 4, when the screen is hit, it can prevent the screen from hitting the bottom of the fixing frame 1 and causing damage to the screen, thereby protecting the screen.

[0029] Working principle: When using the fixed structure of the cabin ceiling screen, first, before installing the fixing frame 1 on the roof, pull the clamp 304, open it, and then insert the display screen into the pressure relief strip 305 on the surface of the clamp 304, loosen the clamp 304, and stretch the spring 301 to drive the sliding block 302 to position and clamp the clamp 304 to complete the fixation. Then, rotate the clamp 304 through the damping shaft 303, and screw the display screen into the surface of the fixing frame 1 to complete the installation. When the distance between the display screen and the passenger needs to be adjusted, start the drive motor 204 to drive the threaded transmission rod 203 to rotate, and at the same time, the sliding support plate 202 on the surface of the threaded transmission rod 203 moves along the slide groove 2 opened on the inner wall of the fixing frame 1 to adjust the distance from the passenger, so as to facilitate better viewing. When the display screen is closed, if it is hit, the display screen squeezes the protective plate 4, and presses the compression spring 403 to relieve the impact and protect the display screen. This is the working principle of the fixed structure of the cabin ceiling screen.
