Problems solved by technology

Since the driving force of multiple degrees of freedom comes from the magnetic force of multiple electromagnets, electromagnetic interference will be generated between multiple electromagnets, which will affect the anti-shake and focusing performance; and, in the current development of lens modules towards miniaturization, electromagnetic Insufficient driving force, small anti-shake angle, affecting image quality

Abstract

The invention relates to a lens module and a mobile terminal. The lens module comprises a first bearing seat, at least one first lens is arranged in the first bearing seat, and the first lens is provided with a first optical axis; the second bearing seat is located below the first bearing seat, at least one second lens is arranged in the second bearing seat, and the second lens is provided with a second optical axis; the at least two memory alloy wires are connected with the first bearing seat and the second bearing seat, and the memory alloy wires can drive the second bearing seat to move relative to the first bearing seat in the second optical axis direction; or the memory alloy wire can drive the second bearing seat to move relative to the first bearing seat in the direction perpendicular to the second optical axis; or the memory alloy wire can drive the second bearing seat to move relative to the first bearing seat, so that the second optical axis inclines relative to the first optical axis. According to the invention, the plurality of memory alloy wires are connected between the two lens bearing seats, and the zooming and optical anti-vibration functions are realized through the deformation of the memory alloy wires.

Description

technical field [0001] The present disclosure relates to the technical field of photography, and in particular to a lens module and a mobile terminal. Background technique [0002] With the continuous development of science and technology, more and more mobile terminals are equipped with lens modules to realize the functions of taking pictures and taking pictures, and the lens modules also have auto-focus (AF) function, lens anti-shake function (OIS), zoom (Zoom) function to improve the captured image quality. [0003] In related technologies, taking a mobile phone as an example, multiple lens modules are used to realize the zoom function, which takes up a large amount of mobile phone space, is not conducive to the miniaturization of the whole machine, and increases the cost. [0004] In addition, by setting the electromagnetic drive (voice coil motor drive) to adjust multiple degrees of freedom of the lens module, the anti-shake function and auto-focus function are realize...
