Optical anti-shake structure, camera module with optical anti-shake structure and terminal equipment with optical anti-shake structure

Abstract

The invention discloses an optical anti-shake structure, a camera module with the same and a terminal device, the optical anti-shake structure comprises a carrier, the carrier comprises a base body part and a moving part, the moving part is provided with an accommodating area for accommodating an image sensor, and the moving part is movably arranged relative to the base body part; the shape memory part is connected with the base body part and the moving part, and when the shape memory part stretches and deforms, the moving part moves relative to the base body part. According to the optical anti-shake structure, the camera module with the same and the terminal equipment provided by the invention, the image sensor is driven to move through the telescopic deformation of the shape memory part, so that an optical anti-shake function is realized, the imaging quality of the camera module in a moving state and the imaging quality of the camera module in shooting an object in the moving state are improved, and the imaging quality of the camera module in the moving state is improved. In addition, mutual magnetic interference with other parts with magnets can be avoided, and the use performance of the optical anti-vibration structure is ensured.

Description

technical field [0001] The present invention generally relates to the technical field of camera equipment, and in particular to an optical anti-shake structure, a camera module, and a terminal device having the same. Background technique [0002] Existing mobile phones are generally equipped with one or more camera modules. The camera module is equipped with an optical anti-shake structure, and the optical anti-shake structure is used to compensate for the offset of the imaging optical path caused by hand shaking when the user holds the mobile phone to shoot. to significantly reduce photo blur. [0003] At present, the optical anti-shake structure generally includes a driving magnet and a coil, and through the electromagnetic driving cooperation of the driving magnet and the coil, the coil drives the image sensor to move, thereby realizing the optical anti-shake. However, when the above optical anti-shake structure is assembled in a mobile phone, the driving magnet in the o...
