Problems solved by technology

The lens barrel is provided with three longitudinal sections at equal intervals on the outside of the barrel body, while the inner wall of the barrel is still a circular through-hole structure. Such a structure causes the wall thickness of the part of the lens barrel with longitudinal sections to be relatively thin, making the lens barrel Uneven strength, decreased overall strength, and shortened service life

Abstract

The invention relates to a lens, which comprises a lens tube, a lens group and a light shielding assembly, wherein the lens group is arranged in the lens tube; the light shielding assembly and the lens group are arranged in the lens tube in a corresponding arrangement way; the lens group comprises at least one lens and at least one edge cutting lens alternately arranged with the lens; the edge cutting lens comprises an aspherical work part, a connecting part and at least one longitudinal cutting surface; the connecting part surrounds the aspherical work part and is connected with the aspherical work part; the lens tube comprises a lens installing region and an edge cutting lens installing region; the edge cutting lens installing part comprises at least one longitudinal cutting plate corresponding to the longitudinal cutting surface and an arc-shaped side wall connected with the longitudinal cutting plate; the connecting part comprises an arc-shaped lug boss corresponding to the arc-shaped side wall. The lens provided by the invention has the advantages that the structure is reasonable; the intensity is high; the service life is long; the dimension is small; the screen occupation ratio is high.

Description

technical field [0001] The invention relates to a lens, in particular to an edge-cutting lens; and a camera module including the lens. Background technique [0002] Chinese patent 200910301782.1 discloses a lens barrel and a lens module for its application. The lens barrel is provided with three longitudinal sections at equal intervals on the outside of the barrel body, while the inner wall of the barrel is still a circular through-hole structure. Such a structure causes the wall thickness of the part of the lens barrel with longitudinal sections to be relatively thin, making the lens barrel The strength is uneven, the overall strength is reduced, and the service life is shortened. [0003] In recent years, portable electronic products have developed rapidly. For example, mobile phones and tablet computers have flooded the lives of modern people, and imaging devices mounted on portable electronic products have also developed rapidly. With the development of science and tec...
