Problems solved by technology

[0002] In the existing dual-lens camera system, the positions of the two lens driving modules are usually quite close, so the magnets arranged in different lens driving modules are likely to generate magnetic interference (magnetic interference), and cause the lens to be carried along with the lens. The focusing speed and accuracy of the moving lens are affected

Abstract

The invention discloses a lens driving mechanism, which is used to drive a first lens and a second lens to move, wherein external light enters the first lens and the second lens along an incident direction. The aforementioned lens drive mechanism includes a first base, a first drive assembly and a second drive assembly, wherein the first lens is movably connected to the first base. The first driving assembly has a corresponding first magnet and a first coil for driving the first lens to move. The second drive assembly has a corresponding second magnet and a second coil for driving the second lens to move, wherein the first magnet is adjacent to the second magnet, and the magnetic pole direction of the first magnet is parallel to the incident direction.

Description

technical field [0001] The invention relates to a lens driving mechanism, in particular to a lens driving mechanism capable of moving the lens through electromagnetic force. Background technique [0002] In the existing dual-lens camera system, the positions of the two lens driving modules are usually quite close, so the magnets arranged in different lens driving modules are likely to generate magnetic interference (magnetic interference), and cause the lens to be carried along with the lens. The focusing speed and accuracy of the moving lens will be affected. In view of this, how to design a dual-lens camera system that can prevent magnetic interference between different lens drive modules has become an important issue. Contents of the invention [0003] In view of the foregoing existing problems, an object of the present invention is to provide a lens drive mechanism for driving a first lens and a second lens to move, wherein external light enters the first lens and the...
