Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a waterproof automotive lens structure. Background Technology

[0002] The structural design of automotive mirrors is primarily based on optical principles. Their main function is to expand the driver's field of vision, helping them better observe traffic conditions around the vehicle and thus preventing traffic accidents. Reflective mirrors allow drivers to see the road conditions behind, to the sides, and to the rear of the vehicle, ensuring driving safety. Convex and concave lenses are used to meet different visual needs: convex lenses magnify the field of vision, helping drivers see distant objects better, while concave lenses narrow the field of vision, helping drivers see nearby objects more clearly. Automotive mirrors typically use materials such as glass, resin, and PC, each with its own advantages and disadvantages. The structure of automotive mirrors is a crucial automotive component, ensuring vehicle safety during driving. However, common automotive mirrors on the market are prone to moisture penetration after exposure to significant temperature differences. This moisture easily condenses into water droplets, which can seep into the mirror material, causing deformation or damage. Furthermore, after repeated disassembly and reassembly using clips, the clips can loosen and deform, affecting the locking effect and making the mirrors prone to falling off after exposure to bumps. Utility Model Content

[0003] This disclosure relates to an automotive lens structure that prevents water vapor penetration. When the lens body is in use, a chemical hydrophobic film is sprayed on the front end of the lens body. When water vapor is generated at the front end of the lens body, the chemical hydrophobic film can isolate the water vapor and prevent water vapor penetration. Even if water vapor slightly penetrates, it can be blocked by the rubber inner part. After the inner part blocks the water vapor, the water vapor enters the interior of the collection tank through the guide groove and is then discharged through the liquid outlet, preventing water vapor from continuously penetrating into the interior.

[0004] The first aspect of this disclosure provides a water-vapor-resistant automotive lens structure, specifically comprising: a lens body; the front end of the lens body is coated with a chemical hydrophobic film, and an inner component is bonded to the rear end of the lens body. The inner component is made of a water-vapor-resistant synthetic rubber material, and the front end of the inner component is attached to the rear of the lens body; a fixing structure; the fixing structure is installed at the rear of the lens body, and a guide rod is slidably mounted on the front end of the plastic material through a support plate structure. A spring is fitted around the outside of the guide rod, the outer end of the spring contacts the inner side of the support plate structure, the front end of the guide rod is fixedly connected to a limiting head structure, the inner end of the spring contacts the outer side of the guide rod, and the inner end of the L-shaped limiting head structure is an arc-shaped structure.

[0005] In at least some embodiments, connecting blocks are fixed at both the upper and lower ends of the lens body, the rear end of the connecting blocks is fixedly connected to the rear plate assembly, and the rear plate assembly is bonded to the rear of the inner component; a connecting head assembly is integrally formed at the rear of the rear plate assembly, and an arc-shaped locking block assembly is provided on the outside of the circular connecting head assembly, the locking block assembly having a circular cross-section; the front end of the inner component has evenly arranged guide grooves, the bottom of the vertically arranged guide grooves is connected to the converging groove, the converging groove is opened at the bottom of the front end of the inner component, the bottom of the converging groove has a liquid outlet, and the upper and lower sides of the inner component have grooves, with connecting blocks embedded inside the grooves.

[0006] In at least some embodiments, the rear end of the fixing structure is provided with an insertion groove, a connector assembly is inserted into the insertion groove, the connector assembly is bonded to the inside of the insertion groove with adhesive, and a ring-shaped, uniformly arranged slot is formed inside the insertion groove, with a locking block assembly embedded inside the slot; the outside of the fixing structure is provided with a ring-shaped, uniformly arranged outer groove, the limiting head structure moves inside the outer groove, and the L-shaped support plate structure is located at the outer end of the outer groove; a flexible rubber support ring structure is bonded to the rear of the fixing structure, the front end of the support ring structure is provided with an auxiliary block, and the rear of the auxiliary block is provided with a wedge-shaped groove.

[0007] This utility model provides a waterproof and vapor-permeable automotive lens structure, which has the following beneficial effects:

[0008] When the lens body is in use, the front end of the lens body is coated with a chemical hydrophobic film. When water vapor is generated at the front end of the lens body, the chemical hydrophobic film can isolate the water vapor and prevent water vapor from penetrating. Even if water vapor slightly penetrates, it can be blocked by the inner part of the rubber material. After the inner part blocks the water vapor, the water vapor enters the interior of the collection tank through the guide groove and is then discharged through the liquid outlet, preventing water vapor from continuously penetrating into the interior.

[0009] When the lens body is connected to the car through the fixing structure, the limiting head structure is displaced by force, which squeezes the spring on the outside of the guide rod. After the locking, the limiting head structure is locked and fixed to the installation position. After the lens body is disassembled and installed multiple times, the spring pushes the limiting head structure to reset. This will not cause the locking structure to loosen or age, thus affecting the fixing effect. The limiting head structure uses the spring force to ensure the fixing effect and prevent the lens body from falling off after vibration. Attached Figure Description

[0024] This utility model proposes a waterproof automotive lens structure, comprising: a lens body 1; the front end of the lens body 1 is coated with a chemical hydrophobic film 101 to guide adhering water vapor and reduce the probability of penetration; an inner component 106 is bonded to the rear end of the lens body 1, the inner component 106 is made of a water-repellent synthetic rubber material, which can block water vapor and guide it downwards to improve the anti-penetration effect; the front end of the inner component 106 is attached to the rear of the lens body 1; a fixing structure 2; the fixing structure 2 is installed at the rear of the lens body 1, and a guide rod 205 is slidably mounted on the front end of the plastic material through a support plate structure 204 to guide... A spring is fitted around the outside of the rod 205. The outer end of the spring contacts the inner side of the support plate structure 204. The front end of the guide rod 205 is fixedly connected to the limiting head structure 206. The inner end of the spring contacts the outer side of the guide rod 205. The inner end of the L-shaped limiting head structure 206 is an arc-shaped structure. The spring is continuously stressed, controlling the displacement of the guide rod 205 and the limiting head structure 206, so that the limiting head structure 206 is engaged with the installation position, improving the engagement and fixing effect. Even after the lens body 1 is disassembled and installed multiple times, the spring can still push the limiting head structure 206 to move and engage, ensuring the engagement and fixing effect and preventing loosening and detachment.

[0025] In this embodiment of the disclosure, such as Figure 3 and Figure 4 As shown, connecting blocks 102 are fixed at both the upper and lower ends of the lens body 1 for connecting and supporting the rear plate assembly 103. The rear end of the connecting block 102 is fixedly connected to the rear plate assembly 103, which is bonded to the rear of the inner part 106. A connector assembly 104 is integrally formed at the rear of the rear plate assembly 103. The circular connector assembly 104 has an arc-shaped locking block assembly 105 on its exterior. The locking block assembly 105 has a circular cross-section and is inserted into the slot 202 for locking. Fixed; the front end of the inner component 106 is provided with uniformly arranged guide grooves 107. The bottom of the vertically arranged guide grooves 107 is connected to the collecting groove 108, so that after the water vapor initially penetrates, it is blocked by the inner component 106, so that the water vapor is guided downward and discharged through the collecting groove 108 and the liquid outlet, thus preventing the water vapor from continuously penetrating. The collecting groove 108 is opened at the bottom of the front end of the inner component 106, and the bottom of the collecting groove 108 is provided with a liquid outlet. The upper and lower sides of the inner component 106 are provided with grooves, and the connecting block 102 is embedded in the inside of the groove.

[0026] In this embodiment of the disclosure, such as Figure 5 and Figure 6As shown, the rear end of the fixing structure 2 is provided with an insertion groove 201. A connector assembly 104 is inserted into the insertion groove 201 and is bonded to the inside of the insertion groove 201 with adhesive, which improves the connection effect between the lens body 1 and the fixing structure 2 and increases the connection strength. The inside of the insertion groove 201 is provided with a ring of uniformly arranged slots 202. A locking block assembly 105 is embedded in the slots 202 to improve the positioning and locking effect and prevent the connector assembly 104 from detaching from the inside of the insertion groove 201. The outside of the fixing structure 2 is provided with a ring of uniformly arranged outer grooves 203. The limiting head structure 206 moves inside the outer groove 203, causing the limiting head structure 206 to be guided and displaced. The L-shaped support plate structure 204 is located at the outer end of the outer groove 203. A flexible rubber support ring structure 207 is bonded to the rear of the fixing structure 2. An auxiliary block 208 is provided at the front end of the support ring structure 207, and a wedge-shaped groove is provided at the rear of the auxiliary block 208 to improve the flexibility of the auxiliary block 208. After the lens body 1 and the fixing structure 2 come into contact with the installation position, the auxiliary block 208 assists in pushing and supporting the lens body 1, so that the lens body 1 will not wobble after being snapped and fixed.

[0027] The working principle of this embodiment is as follows: When the lens body 1 is needed, adhesive is applied to the inside of the insertion slot 201 in advance. Then, the connector assembly 104 is inserted into the insertion slot 201, and the locking block assembly 105 is inserted into the locking slot 202 to lock together, thereby improving the connection effect and connection strength between the lens body 1 and the fixing structure 2, so that the fixing structure 2 will not detach from the lens body 1. Then, the lens body 1 is installed, so that the installation position is inserted into the rear end of the fixing structure 2, and the limiting head structure 206 is elastically displaced by the spring to lock together with the installation position, so as to avoid loosening after multiple installations and disassemblies. After installation, the auxiliary block 208 elastically supports the lens body 1 to prevent the lens body 1 from shaking. After water vapor adheres to the outside of the lens body 1, it can be blocked by the chemical hydrophobic film 101 to prevent water vapor penetration. Even if water vapor slightly penetrates, it can be blocked by the inner part 106, so that the water vapor is guided downward inside the guide groove 107 and discharged through the collection groove 108.
