ABSTRACT:
A lens module includes a lens set, a rotation base, an outer case, elastic members, a driving device having a stepping motor and a base frame. The lens set is fixed inside the rotation base that is elastically arranged between an upper case and a lower case by elastic members. By clockwise/counterclockwise rotation of the stepping motor outside the rotation base, the rotation base is driven to rotate. Furthermore, a plurality of sloped grooved surface that goes from shallow to deep and faces downwards is disposed on circular bottom surface of the rotation base and each sloped grooved surface presses homogeneously on a corresponding supporting point of the power case by elastic members. When the rotation base rotates, the sloped grooved surface moves relative to the supporting point so that the gap between the shallow and deep grooved surfaces becomes focusing travel. Furthermore, the base frame assembles or disassembles with the lens module by a fastening mechanism. When being assembled, firstly the base frame is adhered to the printed circuit board and then the lens module is fastened on the base frame. If necessary, the lens module is dismounted from the base frame without any damage caused during the disassembling process.
