Abstract: A lens module includes a base, a lens assembly, a bearing member including fixing and rotating frames, a shape memory alloy wire assembly including first and second shape memory alloy (SMA) wires, and at least one first and second wire-binding clamp members. The first SMA wires drive rotating frame to rotate relative to base about a first direction, and the second SMA wires drive the fixing frame to rotate relative to the rotating frame about a second direction. The first and second directions are perpendicular to each other and perpendicular to optical axis of the lens assembly. The rotating frame includes first and second rotating side plates. Each first wire-binding clamp member is connected to two first SMA wires, and each second wire-binding clamp member is connected to two second SMA wire. The lens module has low cost and occupies a small space, and the magnetic interference can be avoided.
