Abstract

A lens driving mechanism is provided, configured to drive an optical lens, including a bottom plate, a movable portion, an elastic member, and a biasing assembly. The movable portion is disposed on the bottom plate and has a base and a holder, wherein the holder is configured to hold the optical lens, and the holder is movably connected to the base. The elastic member connects the movable portionto the bottom plate. The biasing assembly connects the bottom plate and the movable portion and is configured to force the movable portion to move relative to the bottom plate. When the holder moves to a lower-limit position relative to the base, the holder comes into contact with the elastic member.

Description

technical field [0001] The invention discloses an optical drive mechanism, in particular to an optical drive mechanism that restricts the movement of a carrier and an optical lens through an outer frame. Background technique [0002] With the development of technology, many electronic devices (such as tablet PCs or smart phones) are miniaturized and equipped with lens modules to have the function of taking pictures or recording videos. When the user uses the electronic device equipped with the lens module, there may be shaking, which makes the image captured by the lens module blurred. Nowadays, people's requirements for high-quality images and miniaturization of electronic products are increasing day by day, which makes electronic products with excellent shockproof function and miniaturized lens modules more and more important. Contents of the invention [0003] The main purpose of the present invention is to provide an optical driving structure so that the optical drivi...
