[0029] Embodiment 1:

[0030] Reference Figure 1-5 , a vehicle-mounted liquid crystal display screen with an electrostatic protection structure, comprising a shell 1, a liquid crystal display screen body 2 is arranged on the front side of the shell 1, a sun visor 9 is fixedly connected to the top side of the shell 1, two cooling fans 10 are installed at the front end of the sun visor 9, the outer wall of the sun visor 9 is provided with a dustproof net 11, a magnetic suction plug-in 12 fixedly connected to the rear side of the inner wall of the dustproof net 11 is prepared by a magnet, a magnetic suction groove 13 opened on the front side of the sun visor 9 is provided with an iron sheet, and the magnetic suction plug-in 12 is magnetically attracted to the inside of the magnetic suction groove 13, a data interface 14 for an external data cable is arranged at the bottom end of the front side of the shell 1, and a dustproof rubber plug 15 is arranged on the front side of the data interface 14, which can be used to block the data interface 14 when it is not in use to prevent dust from entering the data interface 14, so as to protect the data interface 14;

[0031] Specifically, the entire display screen is coated with a special coating with antistatic function, which can absorb or release static electricity, thereby reducing the generation and accumulation of static electricity. The device as a whole is tilted forward to a certain extent, and in conjunction with the sun visor 9, it can block sunlight to a certain extent, reducing the lack of external sunshade measures for the vehicle during driving or parking in summer, to protect the LCD screen body 2, and through the cooling fan 10 blowing air to the bottom side, to increase the air flow on the surface of the LCD screen body 2, thereby cooling the surface of the LCD screen body 2 to prevent the temperature from being too high, and then protecting the internal electronic equipment from overheating, so as to extend the service life of the LCD screen body 2. The dustproof net 11 can reduce the dust at the air inlet of the cooling fan 10 to a certain extent, so that it is blocked by the dustproof net 11, reduce the accumulation of dust on the cooling fan 10, and prevent excessive dust from affecting the normal operation of the cooling fan 10. The magnetic suction plug-in 12 on the dustproof net 11 can be detached from the magnetic suction groove 13 at the front end of the sun visor 9, so that the dustproof net 11 can be detached from the sun visor 9, and then the dustproof net 11 can be cleaned.

[0032] Embodiment 2:

[0033] As one of the optimized structural designs for Example 1, Figure 1-Figure 3As shown, the liquid crystal display body 2 is connected to a plurality of rotating rods 6, and a plurality of ball sleeves 4 installed on the rear side of the liquid crystal display body 2 are provided with steering balls 5 inside, and the rear end of the steering balls 5 is fixedly connected to the front end of the rotating rod 6, and both ends of the rotating frame 8 at the rear end of the shell 1 are fixedly connected to the two sides of the rear end of the inner wall of the shell 1, and the front side of the rotating frame 8 is rotatably connected to a connecting rod 7, and both ends of the connecting rod 7 are rotatably connected to the rear ends of the plurality of rotating rods 6; a dustproof rubber sleeve 3 is provided on the front side of the shell 1, and the rear outer periphery of the dustproof rubber sleeve 3 is fixedly connected to the shell 1, and the rear inner periphery of the dustproof rubber sleeve 3 abuts against the outer periphery of the liquid crystal display body 2;

[0034] Specifically, by pressing any one end of the left or right end of the LCD screen body 2, the rear end of the LCD screen body 2 will sink backward, so that the ball sleeve 4 connected to the rear side of one end applies force to the steering ball 5, so that the steering ball 5 rotates in the ball sleeve 4 and pushes the rotating rod 6 connected to the rear end to rotate on one end of the connecting rod 7. At the same time, the connecting rod 7 rotates on the rotating frame 8, and the other end of the connecting rod 7 applies force forward, so that the rotating rod 6 at the other end connected thereto pushes the steering ball 5 connected thereto to rotate inside the ball sleeve 4 at the other end, thereby tilting the other end of the LCD screen body 2 forward, thereby changing the angle of the LCD screen body 2, and reducing the visual impact of the reflection by changing the angle. The dustproof rubber sleeve 3 has a multi-layer soft structure and can be stretched and elongated. It can be stretched and deformed as the angle of the LCD screen body 2 changes, thereby continuously sealing the gap between the LCD screen body 2 and the shell 1, reducing dust from entering the interior of the shell 1, thereby preventing dust from affecting the internal electronic components.

[0035] Working principle: When reflection appears on the screen, you can press any left or right end of the LCD screen body 2, and the rear end of the LCD screen body 2 will sink backward, so that the ball sleeve 4 connected to the rear side of one end applies force to the steering ball 5, so that the steering ball 5 rotates in the ball sleeve 4 and pushes the rotating rod 6 connected to the rear end to rotate on one end of the connecting rod 7. At the same time, the connecting rod 7 rotates on the rotating frame 8, and the other end of the connecting rod 7 applies force forward, so that the rotating rod 6 at the other end connected to it pushes the steering ball 5 connected to it to rotate inside the ball sleeve 4 at the other end, thereby tilting the other end of the LCD screen body 2 forward, and then changing the angle of the LCD screen body 2 to reduce the impact of reflection. In hot weather, the cooling fan 10 will blow air to the bottom side to increase the air flow on the surface of the LCD screen body 2, thereby cooling the surface of the LCD screen body 2 to prevent the temperature from being too high, thereby protecting the internal electronic equipment from overheating. While dissipating heat, the dustproof net 11 can reduce the dust at the air inlet of the cooling fan 10 to a certain extent, so that the dust is blocked by the dustproof net 11, and the accumulation of dust on the cooling fan 10 is reduced. The magnetic suction plug 12 on the dustproof net 11 can be detached from the magnetic suction groove 13 at the front end of the sun visor 9, so that the dustproof net 11 can be detached from the sun visor 9, and then the dustproof net 11 can be cleaned.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
