Patent ID: 8274595

Claim:
A camera module, comprising: a circuit board; an image sensor mounted on the circuit board; and a first lens module and a second lens module aligned with the image sensor, wherein the first lens module comprises a first barrel disposed on the circuit board, a second barrel movably received in the first barrel, a first lens received in the second barrel, a driving apparatus configured for driving the first barrel to rotate, and a leaning member fixed on the circuit board and arranged outside of the first barrel, the first barrel has a cam groove formed along a circumference thereof, and the second barrel has a guiding bar extending through the cam groove and leaned against the leaning member, such that when the driving apparatus drives the first barrel to rotate, the second barrel together with the first lens is driven to move along an optical axis of the first lens; and wherein the second lens module comprises a fixing barrel fixed on the circuit board, a movable barrel received in the fixing barrel, a plurality of elastic members interconnecting the fixing barrel and the movable barrel, a second lens received in the movable barrel, a first magnetic member fixed on an inner wall of the fixing barrel, and a second magnetic member fixed on an outer wall of the movable barrel, and the first magnetic member and the second magnetic member are arranged for cooperatively generating a magnetic field for driving the movable barrel together with second lens to move along an optical axis of the second lens.
