Abstract

A lens module is prepared for arranging a regulation magnetic iron in lens cone, setting lens in lens cone, arranging a positioning magnetic iron set in sleeve, setting said lens cone in internal of said sleeve, maintaining balance of lens cone by interaction of positioning magnetic iron set and regulation magnetic iron.

Description

【Technical field】 [0001] The invention relates to a lens module, in particular to a lens module capable of reducing friction during focusing. 【Background technique】 [0002] Most of the camera lens modules are equipped with focusing mechanisms to meet the needs of shooting nearer and farther images respectively. Generally, the focusing mechanism utilizes a mechanical transmission device to control the position transformation of each component of the lens module to perform focusing. However, when a mechanical transmission device is used for focusing, the strength and adjustment accuracy of the focusing mechanism may be affected due to frequent friction between various transmission components, which shortens the service life of the lens module and affects the shooting quality. 【Content of invention】 [0003] In view of this, it is necessary to provide a lens module that can reduce friction during the focusing process and prolong the service life. [0004] A lens module inc...
