[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model provides a vehicle screen module anti-detachment installation device, which includes: an installation frame 1, a protective frame 2 inside the installation frame 1, and a screen module body 3 inside the protective frame 2. The left and right surfaces of the protective frame 2 and the left and right inner walls of the installation frame 1 are respectively provided with spherical protrusions 8 and contoured grooves 9. When installing the vehicle screen module, the spherical protrusions 8 are located inside the contoured grooves 9. The above components cooperate to form the basic structure of the vehicle screen module installation device. The spherical protrusions 8 and contoured grooves 9 improve the stability of the protective frame 2 after it enters the installation frame 1, while the arc structure reduces the resistance encountered during the downward pressure of the protective frame 2.

[0024] Specifically, after the screen module body 3 is inserted into the protective frame 2, the protective frame 2 is pressed into the mounting frame 1. The arc structure of the spherical protrusion 8 reduces the force-bearing surface, thereby reducing the resistance encountered by the protective frame 2 during the pressing process. After the spherical protrusion 8 enters the contour slot 9, it directly prevents the protective frame 2 from naturally detaching from the mounting frame 1.

[0025] The lower inner wall of the mounting frame 1 is provided with multiple grooves 10, which are not interconnected. The grooves 10 are used to provide space for the power cord of the screen module body 3. The left and right walls of the mounting frame 1 are respectively provided with sealing blocks 14, which penetrate into the interior of the mounting frame 1. Multiple lead tubes 15 are fixedly connected to the surface of the sealing block 14. The lead tubes 15 pass through the sealing block 14. The sealing block 14 and the lead tubes 15 cooperate to improve the convenience of connecting the power cord of the external screen module body 3.

[0026] Specifically, after the protective frame 2 is pressed into the mounting frame 1, the screen module body 3 simultaneously enters the mounting frame 1. At this time, the sealing block 14 can be pulled out to move the power cord on the left and right sides of the mounting frame 1, thereby pressing the power cord into the groove 10. At the same time, the external connector of the power cord is extended outward through the lead tube 15.

[0027] A pressure plate 4 is provided on the upper surface of the mounting frame 1. The lower surface of the pressure plate 4 is in contact with the upper surfaces of the mounting frame 1, the protective frame 2, and the screen module body 3. The pressure plate 4 is used to limit the range of motion of the protective frame 2. Reinforcing bolts 7 are provided at the four corners of the pressure plate 4. The lower end of the reinforcing bolts 7 passes through the pressure plate 4 and is threaded to the mounting frame 1. The reinforcing bolts 7 increase the stability of the pressure plate 4 when it is in action. A first protective pad 5 and a second protective pad 11 are fixedly connected to the lower surface of the pressure plate 4. The height of the second protective pad 11 is greater than the height of the first protective pad 5, and the first protective pad 5 does not contact the second protective pad 11. The gap between the first protective pad 5 and the second protective pad 11 forms an isolation cavity. The first protective pad 5 and the second protective pad 11 are used to reduce the risk of the pressure plate 4 wearing the screen module body 3. The surface of the first protective pad 5 is provided with an exhaust hole 6, which is interconnected with the isolation cavity. The exhaust hole 6 is used to increase the flexibility of the first protective pad 5 and to discharge excess air inside the isolation cavity.

[0028] Specifically, after the protective frame 2 is pressed into the mounting frame 1, the pressure plate 4 is placed on the upper surface of the protective frame 2, and then the reinforcing bolt 7 is tightened. During the downward feeding of the reinforcing bolt 7, the pressure plate 4 is pressed down to press the second protective pad 11 into the docking slot 12, and the other protective pad 5 is compressed and deformed. When the pressure plate 4 is subjected to impact force, the first protective pad 5 and the second protective pad 11 are deformed under pressure, thereby mitigating the impact of the impact force on the pressure plate 4 on the screen module body 3. At the same time, the air inside the isolation cavity is discharged through the exhaust hole 6, further mitigating the impact force on the edge of the screen module body 3.

[0029] The lower surface of the second protective pad 11 and the upper surface of the protective frame 2 are respectively provided with a storage notch 13 and a docking slot 12. The lower surface of the first protective pad 5 contacts the edge of the screen module body 3. The second protective pad 11 covers the gap between the screen module body 3 and the protective frame 2. The lower end of the second protective pad 11 is located inside the docking slot 12. The part of the screen module body 3 near the protective frame 2 is located inside the storage notch 13. The docking slot 12 and the storage notch 13 cooperate to increase the sealing effect of the second protective pad 11.

[0030] Specifically, the second protective pad 11 is pressed into the docking slot 12, while the edge of the screen module body 3 is simultaneously inserted into the storage notch 13. At this time, the gap between the screen module body 3 and the protective frame 2 is completely covered by the second protective pad 11, thereby preventing external dust and impurities from entering the interior of the mounting frame 1.

[0031] Working principle: When installing the vehicle screen module, first place the screen module body 3 inside the protective frame 2, then press the protective frame 2 down to press it into the mounting frame 1, then place the pressure plate 4 on the upper surface of the protective frame 2, and then fix the pressure plate 4 with the reinforcing bolt 7. During the process of the pressure plate 4 being pressed down by the reinforcing bolt 7, the second protective pad 11 is directly pressed into the docking slot 12. At this time, the second protective pad 11 seals the gap between the screen module body 3 and the protective frame 2. After the pressure plate 4 is subjected to downward pressure, the first protective pad 5 and the second protective pad 11 deform to buffer the pressure, and the air pressure inside the isolation chamber is discharged through the exhaust hole 6.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
