MOTOR, CAMERA MODULE, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2024/002288

A1

The present application relates to the technical field of terminals. Disclosed are a motor, a camera module, and an electronic device. The motor comprises a rotor structure, a stator structure, a first sliding shaft, a second sliding shaft, and a bearing part. The bearing part is provided with a first sliding groove matching the first sliding shaft in shape and a second sliding groove matching the second sliding shaft in shape. In an assembled state, the first sliding shaft is snap-fitted in the first sliding groove in the bearing part so as to restrict a movement direction of the relative movement of the rotor structure and the stator structure, and the second sliding shaft is snap-fitted in the second sliding groove in the bearing part so as to restrict the rotor structure from being separated from the stator structure. Compared with acting points of resultant forces under different postures, a triangle defined by the three-point holding bearing of the motor is more stable, and the motor is always held on three bearing points in a moving process. Therefore, the three-point holding bearing solution can effectively improve the operation stability of the motor and reduce the micro-swing amplitude, thereby optimizing dynamic inclination characteristics and reducing the operation noise of the motor.
