Abstract

An anti-shake device comprises a base, a bearing body movably arranged on the base and a driving piece driving the bearing body to move relative to the base, wherein the driving piece comprises a conductive structure arranged on the bearing body, a plurality of positive electrode pads arranged on the base and an SMA wire connected with each positive electrode pad and the conductive structure, and when current flows into the SMA wire from the positive electrode pads, the SMA wire is heated to deform, so traction force F used for pulling the conductive structure is generated on the SMA wire, and the conductive structure drives the bearing body to rotate in a plane parallel to the base under the combined action of the traction force F. According to the anti-shake device provided by the invention, the bearing body is pulled to move by adopting deformation of the SMA wire, shake compensation is realized, and the imaging quality of the prime lens is improved. In addition, the invention also provides a camera module and an electronic device.

Description

technical field [0001] The invention relates to an anti-shake device, a camera module and an electronic device. Background technique [0002] A prime lens refers to a lens with only one fixed focal length, which has the characteristics of fast focusing speed and stable image quality. [0003] In the prior art, the fixed-focus lens usually does not have an anti-shake function, and when shaking or tilting occurs, the image quality will deteriorate. Contents of the invention [0004] In view of this, the present invention provides an anti-shake device, which can be used in a camera module so that the camera module has an anti-shake function. [0005] In addition, it is also necessary to provide a camera module, the camera module having the above-mentioned anti-shake device. [0006] In addition, it is also necessary to provide an electronic device having the above-mentioned fixed-focus lens. [0007] An anti-shake device, comprising a base, a supporting body movably arrang...
