Description

Technical Field

[0001] This utility model belongs to the field of vehicle display technology, specifically a multi-layer vehicle display explosion-proof film corner structure. Background Technology

[0002] During vehicle operation, in-vehicle displays may be impacted by various unexpected situations, leading to screen breakage and potential injury to passengers. To mitigate this risk, explosion-proof films have become an important protective device for in-vehicle displays. However, traditional explosion-proof films often provide insufficient protection at the corners, which are easily damaged by external impacts, thus affecting the overall explosion-proof performance. Therefore, designing an optimized corner structure for multi-layer explosion-proof films for in-vehicle displays is of significant practical importance.

[0003] Meanwhile, a vehicle-mounted display screen with an explosion-proof protection structure, disclosed under the number CN215436270U, ​​relates to the field of vehicle-mounted display screen equipment. Addressing the issues of existing methods for protecting vehicle-mounted displays using film, which not only has a high fault tolerance rate but also poor explosion-proof protection, the following solution is proposed: It includes a vehicle-mounted screen body and an explosion-proof partition. A fence frame is fixedly connected to the four edges of the vehicle-mounted screen body using adhesive, and mounting support frames are welded to both sides of the vehicle-mounted screen body.

[0004] The aforementioned vehicle-mounted display screen with explosion-proof protection structure has its support frame welded to the screen during use. This can damage the screen and require repair, increasing unnecessary expenses. It uses acrylic explosion-proof partitions, which have poor heat resistance and elongation, making them prone to cracking, breakage, and deformation. They are also prone to fading or yellowing in color.

[0005] Therefore, a multi-layer explosion-proof film edge structure for vehicle-mounted displays is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a multi-layer vehicle-mounted display explosion-proof film corner structure, which has the advantages of enhanced explosion-proof performance, reduced risk of fragmentation, easy disassembly, and reduced damage to the explosion-proof film.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer vehicle-mounted display explosion-proof film corner structure, including a vehicle-mounted display screen body, with cuboids fixedly provided on both the left and right sides of the vehicle-mounted display screen body. A rectangular groove is formed inside the cuboid, and a rectangular block is fitted inside the rectangular groove. A circular hole is formed inside the rectangular block, and a base layer is fixedly provided on the upper surface of the rectangular block. The protective film can be fixed using the rectangular block, reducing replacement time and effectively preventing damage to the explosion-proof film when replacement is needed.

[0008] Preferably, spring grooves are provided in the middle of both the front and rear sides of the rectangular groove, a spring is fixedly provided inside the spring groove, and a cylinder is fixedly provided on the other end face of the spring, with the cylinder fitting snugly against the circular hole.

[0009] By adopting the above technical solution, the cylinder can be placed inside the rectangle using a spring, and the rectangle can be fixed by the cylinder, making it convenient to quickly remove the protective film.

[0010] Preferably, the cuboid has a groove inside, and a handle is slidably disposed inside the groove, with the handle and spring passing through each other.

[0011] By adopting the above technical solution, the protective film can be easily removed from the vehicle display screen body via a handle.

[0012] Preferably, a buffer layer is fixedly provided on the upper surface of the base layer, and the buffer layer is made of thermoplastic polyurethane elastomer rubber.

[0013] By adopting the above technical solution, the buffer layer can effectively absorb and disperse the impact force, reduce the stress on the corners, and thus protect the base film layer and the display screen.

[0014] Preferably, an explosion-proof layer is fixedly provided on the upper surface of the buffer layer, and an anti-electric shock layer is fixedly provided on the upper surface of the explosion-proof layer.

[0015] By adopting the above technical solutions, the explosion-proof layer absorbs impact energy and prevents glass or structures from shattering and flying instantly. The anti-static layer blocks the current conduction path, isolating charged components from the human body or environment. When replacing the protective film, static electricity is reduced, which can damage electronic components.

[0016] Preferably, a reinforcing layer is fixedly provided on the upper surface of the anti-electric layer, and an anti-scratch layer is fixedly provided on the upper surface of the reinforcing layer.

[0017] By adopting the above technical solutions, the tensile and tear resistance of the explosion-proof film edges and corners can be significantly improved through the reinforcing layer. The scratch-resistant layer can ensure good scratch resistance without affecting the overall light transmittance and touch performance of the explosion-proof film. The coating also has good self-cleaning properties, and the smooth surface is not easy to attract dust and fingerprints, making it easy to clean and maintain daily.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through its cuboid, rectangular groove, rectangular block, and round hole, makes maintenance and replacement operations more convenient when the explosion-proof film is damaged or needs to be upgraded in terms of protective performance. With the help of these structures, workers can quickly and accurately install the corners of the explosion-proof film, reducing installation time and working time, and increasing work efficiency.

[0020] 2. This utility model uses springs and cylinders to fix the protective film, reducing the risk of the protective film falling off during vehicle operation. The anti-scratch layer ensures good anti-scratch effect without affecting the overall light transmittance and touch performance of the explosion-proof film. The coating also has good self-cleaning properties, with a smooth surface that is not easy to attract dust and fingerprints, making it easy to clean and maintain daily. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following describes an embodiment of this utility model based on its overall structure.

[0028] like Figures 1 to 4As shown, this utility model provides a multi-layer vehicle display explosion-proof film corner structure, including a vehicle display screen body 1, with cuboids 2 fixed on both the left and right sides of the vehicle display screen body 1, a rectangular groove 11 opened inside the cuboid 2, a rectangular block 12 attached inside the rectangular groove 11, a round hole 13 opened inside the rectangular block 12, and a base layer 3 fixed on the upper surface of the rectangular block 12.

[0029] In this embodiment, a spring groove 16 is provided in the middle of both the front and rear sides of the rectangular groove 11. A spring 14 is fixedly provided inside the spring groove 16, and a cylinder 15 is fixedly provided on the other end face of the spring 14. The cylinder 15 is fitted into the circular hole 13. The cylinder 15 can be placed inside the rectangular block 12 through the spring 14. The rectangular block 12 can be fixed through the cylinder 15, which facilitates quick removal of the protective film.

[0030] The interior of the cuboid 2 has a groove 9, and a handle 10 is slidably mounted inside the groove 9. The handle 10 and the spring 14 are connected through the handle 10, so that the protective film can be easily removed from the vehicle display screen body 1.

[0031] A buffer layer 4 is fixedly provided on the upper surface of the base layer 3. The buffer layer 4 is made of thermoplastic polyurethane elastomer rubber. Through the buffer layer 4, the impact force can be effectively absorbed and dispersed, and the stress on the corners can be reduced, thereby protecting the base film layer and the vehicle display screen body 1.

[0032] An explosion-proof layer 5 is fixedly provided on the upper surface of the buffer layer 4, and an anti-static layer 6 is fixedly provided on the upper surface of the explosion-proof layer 5. The explosion-proof layer 5 absorbs the impact energy and prevents the glass or structure from shattering and flying instantly. The anti-static layer 6 blocks the current conduction path and isolates the charged parts from the human body or environment. When replacing the protective film, it reduces the generation of static electricity and prevents damage to electronic components.

[0033] A reinforcing layer 7 is fixedly provided on the upper surface of the anti-electric shock layer 6, and an anti-scratch layer 8 is fixedly provided on the upper surface of the reinforcing layer 7. The reinforcing layer 7 can significantly improve the tensile and tear resistance of the corners of the explosion-proof layer 5. The anti-scratch layer 8 can ensure good anti-scratch effect without affecting the overall light transmittance and touch performance of the explosion-proof layer 5. The coating also has good self-cleaning properties, and the surface is smooth and not easy to attract dust and fingerprints, making it easy to clean and maintain daily.

[0034] Working principle and process of a multi-layer vehicle-mounted display explosion-proof film corner structure:

[0035] Workers use glue to attach cuboid 2 to both sides of the vehicle display screen body 1. The lower ends of the cuboids 12 on both sides of the base layer 3 are placed inside the cuboids 2 on both sides of the vehicle display screen body 1. Workers move the handle 10 by hand, so that the cylinder 15 on the other side of the spring 14 fits into the round holes 13 on the front and rear sides of the cuboid 12, thus fixing the base layer 3. During vehicle operation, the protective film will not fall off due to vehicle shaking. When the protective film needs to be replaced, workers simply pull the handle 10 backward, compressing the spring 14 and causing the cylinder 15 to move with the spring 14, detaching from the cuboid 12. The protective film can then be removed. This convenient operation reduces replacement time, increases efficiency, and serves as the corner structure of the multi-layer vehicle display explosion-proof film.
