SMA MOTOR, CAMERA MODULE AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/105748

A1

Disclosed in the embodiments of the present application are an SMA motor, a camera module, and an electronic device comprising the camera module. The camera module comprises an SMA motor and a lens. The SMA motor comprises a fixed part, a movable part, SMA wires and a plurality of suspension wires. The lens is installed on the inner side of the movable part, and the fixed part is located on the light entry side of the lens. The plurality of suspension wires are connected between the fixed part and the movable part, and are distributed on the periphery of the movable part. The plurality of suspension wires support the movable part, so that the movable part is suspended above the fixed part. A plurality of SMA wires are connected between the fixed part and the movable part. When powered on, the plurality of SMA wires contract and drive the movable part and the lens to move relative to the fixed part. The camera module provided by the present application uses the SMA motor for anti-shake, and there is no sliding friction between the movable part and the fixed part during the anti-shake process of the SMA motor, which reduces a driving algorithm of the camera module.
