WIPO Patent Application WO/2020/243851

A1

Provided is a lens assembly (100), comprising a first base (11), a lens (13), a first memory alloy wire (14), and a second memory alloy wire (15). The lens (13) is slidably mounted in the first base (11), the first base (11) comprises a first side plate (112) arranged on one side of the lens (13) and a second side plate (113) arranged on the other side of the lens (13), one end of the first memory alloy wire (14) is connected to the first side plate (112), the other end thereof is connected to the lens (13), one end of the second memory alloy wire (15) is connected to the second side plate (113), the other end thereof is connected to the lens (13), and both the first memory alloy wire (14) and the second memory alloy wire (15) are arranged to be perpendicular to an optical axis S of the lens (13). According to the lens assembly (100), the first memory alloy wire (14) and the second memory alloy wire (15) are configured to be energized to deform to drive the lens (13) to reciprocate relatively between the first side plate (112) and the second side plate (113) so as to realize optical anti-shake, the problem of magnetic field interference is eliminated, the stability is high, the driving arrangement is simple in structure and easy to mount without additional hall elements, and the use reliability is high in special environments.
