Lens module

Abstract

A lens module, including lenses, imaging chip, Circuit board, movable carry, A magnetic excitation coil and magnetic element, An imaging chip is arrange on that circuit board, The movable carrier is movably connected to the circuit board, and the lens is fixedly arranged on the movable carrier, the magnetic excitation coil is arranged on the movable carrier, the magnetic element is arranged on thecircuit board, and the magnetic excitation coil and the magnetic element can interact to generate driving force so as to drive the movable carrier to move in a plane perpendicular to the optical axisdirection. According to the invention, by adding a movable carry, which is a mechanical structure for realize optical anti-shake, inside that module, by controlling the direction and magnitude of thecurrent loaded into the magnetic excitation coil mounted on the movable carrier, The moving direction and the moving distance of the moving carrier can be controlled so as to drive the lens to move aspecific distance in a specific direction, compensate the tiny movement of the lens caused by the hand shaking when taking a picture, stabilize the optical path, and solve the problem of blurring theimage caused by the hand shaking in taking a picture.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a lens module. Background technique [0002] At present, with the development of mobile communication technology, smart phones have become an indispensable part of people's lives, mobile phone cameras have become the standard configuration of smart phones, and mobile phone users have higher and higher requirements for the shooting effect of mobile phone cameras . Commonly used lens modules include auto-focus lens modules consisting of lenses, VCM motors, imaging chips, and PCB boards, and fixed-focus lens modules consisting of lenses, imaging chips, and PCB boards. None of them can solve the problem of blurred images caused by hand shaking during shooting. In this regard, the general solution is to directly add an optical anti-shake motor to the traditional lens module, but this will cause the production cost of the lens module to be too high, which will affect the market competi...
