AI Technical Summary
It is difficult for the optical lenses of traditional wide-angle cameras to achieve a larger refractive angle while reducing the thickness, making it difficult for the optical lenses to achieve wide angles.
A matrix lens is formed integrally on the side surface of the lens main body. The matrix lens consists of a folded line ring and a convex surface. The folded line ring deflects the light through multiple conical ring structures to reduce the lens thickness. At the same time, the convex surface is located at the center of the folded line ring to enhance light transmission.
The wide-angle performance of the optical lens is achieved, while reducing the lens thickness, improving the clarity of the optical lens, and ensuring the sealing of the lens through the design of the sealing groove and sealing ring.

Technical Field

[0002] Optical lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. A wide-angle camera is a camera that can capture a wider field of view. Its optical lenses are designed to expand the field of view so that the camera can capture more scenery. A wide-angle lens is a photographic lens with a shorter focal length than a standard lens and a larger viewing angle than a standard lens, a longer focal length than a fisheye lens, and a smaller viewing angle than a fisheye lens.
[0003] The optical lenses of traditional wide-angle cameras often obtain a larger refraction angle through thicker materials. However, thicker optical lenses increase the size of the wide-angle camera, which is not conducive to the design of reducing the thickness of the wide-angle camera. When thinner lenses are used, it is difficult to obtain a larger refraction angle, making it difficult for the optical lenses to achieve the purpose of wide angle. Utility Model Content

[0005] The matrix lens comprises a fold line ring and a convex surface. The fold line ring is provided in a plurality and the plurality of fold line rings are sequentially distributed from the outside to the inside. The convex surface is located at the center of the fold line ring.
[0006] As an improvement of the above technical solution, the positioning member includes a limiting groove opened on the inner surface of the sealing groove, and a limiting convex ring integrally formed on the outer surface of the sealing rubber ring, and the limiting convex ring is installed inside the limiting groove.
[0007] As an improvement of the above technical solution, a diversion groove is provided on the outer surface of the sealing rubber ring, and the thickness of the sealing rubber ring is 1 mm greater than the depth of the sealing groove.
[0008] As an improvement of the above technical solution, the broken line ring is a conical ring structure, and the extension lines of the outer inclined surfaces of several broken line rings are located at the same point.
[0009] As an improvement of the above technical solution, the centers of several of the broken line rings coincide.
