Title:
OPTICAL ANTI-SHAKE MOTOR AND CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2023/284282
Kind Code:
A1
Abstract:
An optical anti-shake motor, comprising a base, a carrier, a suspension mechanism, and a driving mechanism. A mounting hole is formed in the base and passes through same. The suspension mechanism comprises an elastic member fixed to the base. The carrier is suspended from the elastic member and movably accommodated in the mounting hole. The driving mechanism comprises at least two driving units. The driving units are separately mounted on the base and located at a side portion of the carrier, and the driving units are used for driving the carrier to move in at least two staggered directions. Each driving unit comprises an SMA wire, and the SMA wire can act on the carrier during closing contraction to enable the carrier to move. Compared with the prior art, the carrier has a larger moving stroke, so that anti-shake at a larger angle can be achieved, thereby improving the anti-shake performance of the optical anti-shake motor; in addition, the driving units are arranged at the side portion of the carrier, so that the thickness of the optical anti-shake motor can be reduced. Also disclosed is a camera module comprising the optical anti-shake motor.
