Abstract
A lens module is disclosed. In the lens module, each group of shape memory alloy wires comprises two ends fixed to one of a base and a lens base, and a drive end located between the two ends, the other one of the base and the lens base is provided with a fixing member. The drive end is connected to the fixing member. The fixing member is provided with a flapper for preventing the drive end from escaping the fixing member. By adding a flapper to the fixing member, it may effectively prevent the shape memory alloy wires from escaping the fixing member. Besides, when one group of shape memory alloy wires operates, it does not result in extra stress to other groups of shape memory alloy wires, thereby prolonging service life of the shape memory alloy wires.
