Zoom assembly, lens assembly and image capturing module

Abstract

The invention discloses a zoom assembly, which is applied to realize focusing of a lens assembly. The zoom assembly comprises a deformation lens, a squeezing member and a driving member, wherein the squeezing member can be bonded with the deformation lens; the deformation lens is a lens capable of changing a focal length by deformation; the driving member is used for driving the squeezing member to squeeze the deformation lens to change the shape of the deformation lens to change the focal length of the deformation lens. The zoom assembly of the invention can be applied to focusing in variousshooting scenes, has a simple structure, is easy to install and occupies small space. The invention also discloses a lens assembly and an image capturing module, which have the above beneficial effects.

Description

technical field

[0001] The invention relates to the technical field of photography, in particular to a zoom assembly, a lens assembly and a camera module. Background technique

[0002] In recent years, as smart phones have gradually penetrated into people's lives, the rapid development of the mobile phone industry has been greatly promoted, and therefore the rapid development of the camera module industry related to smart phones has also been promoted. As mobile phones become thinner and thinner, the available space for camera modules is getting smaller and smaller, prompting researchers to continuously develop camera modules with excellent comprehensive performance such as small size, low energy consumption, and low noise. One of the most critical parts of the mod. In order to improve the quality of the camera, the lens assembly needs to be refocused in different shooting scenarios, so as to adapt to different shooting scenarios.

[0003] At present, the commonly used met...
