Abstract
The invention provides a camera driving motor, a camera module and electronic equipment. Relates to the technical field of electronic equipment shooting. The camera driving motor comprises a base, a seat body and a carrier, the seat body is located on the base, the seat body is provided with a containing cavity, and the carrier is located in the containing cavity; the device further comprises an anti-shake driving structure. The anti-shake driving structure drives the seat body, the carrier and the lens to move along a plane vertical to the optical axis of the lens; the anti-shake driving structure comprises a plurality of groups of driving units, and the plurality of groups of driving units are arranged around the circumferential direction of the base; each driving unit comprises a movable clamping jaw, a fixed clamping jaw, an SMA wire connected with the movable clamping jaw and the fixed clamping jaw, and a plurality of balls arranged between the seat body and the base. The driving structure is an SMA driving structure, the SMA driving structure is simple in structure and small in occupied area, the size of the camera driving motor can be compressed, miniaturization of the camera module is achieved, and the friction coefficient of movement of the base body can be reduced through the balls.
