Abstract
A lens driving device includes fixing bracket, first support frame sleeved on the fixing bracket, second support frame sleeved on the first support frame, rotation assembly configured to make the fixing bracket rotate relative to the first support frame about a first direction and the first support frame rotate relative to the second support frame about a second direction, driving assembly for driving fixing bracket to rotate relative to first support frame about the first direction and driving the first support frame to rotate relative to the second support frame about the second direction, flexible printed circuit board, first elastic support components, and second elastic support components. The lens driving device increases spacing between adjacent two of crossing portions of the shape memory wires so that the shape memory wires have enough space for the movement, preventing the shape memory wires from being interfered with each other during the movement.
