Abstract

The invention relates to an optical driving assembly. The optical driving assembly comprises an optical element with an optical axis, an optical sensor arranged along the optical axis with the optical element, and a driving module for driving the optical sensor to translate in a direction perpendicular to the optical axis. The driving module comprises: a fixed part having a first movable cavity; a movable part arranged in the first movable cavity, wherein the movable part is movably connected with the fixed part in the first direction, and a second movable cavity is formed in the movable part; a bearing part arranged in the second movable cavity, wherein is movably connected with the movable part in the second direction and bears the optical sensor; a first driving assembly comprising a first shape memory alloy wire which is connected with the fixed part and the movable part respectively; and a second driving assembly comprising a second shape memory alloy wire which is respectively connected with the movable part and the bearing part. Through the above mode, the optical sensor performs linear motion on the vertical optical axis in two directions, optical anti-vibration is realized, and the motion in the two directions is independently controlled and does not influence each other.

Description

【Technical field】 [0001] The invention relates to the technical field of optical imaging equipment, in particular to an optical drive assembly. 【Background technique】 [0002] The current Optical Image Stabilization (OIS) solution for smart electronic devices is mainly realized by using a Voice Coil Motor (Voice Coil Motor, VCM) to drive the lens to perform angle correction. However, this type of solution has disadvantages such as high power consumption, limited anti-shake effect, large product size and high unit price. [0003] Therefore, it is necessary to provide a new optical drive assembly to solve the existing defects. 【Content of invention】 [0004] The object of the present invention is to provide an optical drive assembly, through the arrangement of the fixed part, the movable part, the bearing part and the optical sensor and the matching of the first SAM line and the second SAM line, the image optical sensor in the optical drive assembly can be moved to achieve ...
