Abstract
A lens driving device includes a lens module, a first support frame, a second support frame sleeved on the first support frame, a support assembly for suspending the first support frame inside the second support frame, a first flexible printed circuit board (PCB) including folding portions, a second flexible PCB opposite to and independent from the first flexible PCB, and a driving assembly. Each folding portion includes a first fixing portion attached to the first support frame, a second fixing portion attached to the shell, and bent portions connecting the first fixing portion with the second fixing portion by bending. The two flexible PCBs are separately provided in the lens driving device to prevent the risk of disengagement when the two flexible PCBs move, and the folding portions prevent the first flexible PCB from being pulled by the movement of the lens module to be disconnected.
