Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle-mounted lenses, in particular to a vehicle-mounted lens waterproof structure. Background Art
[0002] As the application range of lenses becomes wider and wider, the reliability requirements for lenses are also getting higher and higher. Conventional lenses are usually waterproofed by using a single O-type or ring-type single seal, but in actual applications, such as vehicle-mounted lenses used in outdoor environments, the current waterproof structure is difficult to meet the needs. This is because the outdoor environment is complex and changeable, resulting in inconsistent temperature and humidity inside and outside the lens, which can easily cause water vapor condensation on the inner wall of the lens, affecting the imaging effect. At the same time, if the seal is in a high temperature, high humidity or light environment for a long time, it is easy to age and deform, and the aging of the seal is difficult to observe, and it often develops into severe aging, which will cause waterproof failure and affect the imaging effect of the lens. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:
[0005] A vehicle-mounted lens waterproof structure comprises a lens barrel, wherein a plurality of lenses are arranged in the lens barrel, and the sides of the lenses are connected to the lens barrel, wherein the lens close to the object side is a first lens, and the edge of the object side of the first lens is fixed to the lens barrel through a pressing cap, and further comprises a breathable waterproof membrane, wherein one end of the breathable waterproof membrane is connected to the edge of the first lens, and the other end is connected to the inner wall of the lens barrel or the inner wall of the pressing cap, and a glue dispensing groove is provided at the connection between the pressing cap and the lens barrel, and the pressing cap and the lens barrel are fixed by glue dispensing in the glue dispensing groove.
[0006] By setting up a breathable waterproof membrane, it not only has a waterproof effect, but also can balance the temperature and humidity on both sides, thereby effectively improving the impact of water vapor generated inside the lens. At the same time, it avoids the aging problem of the sealing ring material, so that the lens can maintain good imaging quality for a long time.
[0007] Furthermore, a groove is provided at the edge of the lens barrel and the image side of the first lens, and a sealing ring is provided in the groove.
[0008] Furthermore, a groove is provided at the edge of the pressure cap and the side surface of the lens barrel, and a sealing ring is provided in the groove.
[0009] The sealing ring is arranged at a position where it is not in contact with the outside air and sunlight, which slows down the aging of the sealing ring and prolongs the effective waterproof time. In addition, the sealing ring and the breathable waterproof membrane together achieve multiple waterproofing, and the waterproof effect is better.
[0010] Furthermore, the breathable waterproof film is fixed by waterproof adhesive, and the waterproof adhesive fixation makes the lens more waterproof.
[0011] Furthermore, when the air-permeable waterproof membrane is connected to the inner wall of the pressing cap, the pressing cap and the first lens press and fix the air-permeable waterproof membrane, thereby ensuring that the connection is waterproof.
[0012] The beneficial effects of the utility model are as follows: the vehicle-mounted lens waterproof structure of the utility model, by setting a breathable waterproof film, not only has a waterproof effect, but also can balance the temperature and humidity on both sides to effectively improve the influence of water vapor generated inside the lens, while avoiding the aging problem of the sealing ring material, so that the lens maintains good imaging quality for a long time. By setting a multiple waterproof structure of a breathable waterproof film and a sealing ring, the position where the sealing ring is set is not in contact with the outside air and sunlight, slowing down the aging of the sealing ring, extending the effective waterproof time, and the multiple waterproofing of the sealing ring and the breathable waterproof film makes the waterproof effect better.
