Abstract
A lens driving device includes first and second support frames, lens barrel, anti-shake magnets, anti-shake coils, flexible PCB, metal sheets, and support assembly including support member and first and second guiding posts. Support member includes support plate and first and second support walls. First soft protruding rubbers are respectively provided at positions of top surface of first support frame corresponding first support walls, and second soft protruding rubbers are respectively provided at positions of inner wall of second support frame corresponding to two sides of each second support wall. Compared with the prior art, lens driving device of the present disclosure makes impact limit position of first support walls closer to deflection axis position in first direction, and makes impact limit positions of second support walls closer to deflection axis position in second direction to reduce speed of limit impact, thereby reducing risk of generating particles due to impact.
