Abstract:
1. A lens module comprising: a frame for carrying a image sensor having a photosensitive surface; a guide bar disposed on one side of the frame and parallel to a normal of the photosensitive surface; a lever comprising a pivot part and an extended part, the pivot part coupled with the frame, the extended part capable of rotating around the pivot part; a first lens coupled with the guide bar for sliding along the guide bar, the first lens leaned against the extended part, there being a first distance between the first lens and the photosensitive surface; and a second lens coupled with the guide bar for sliding along the guide bar, the second lens leaned against the extended part, there being a second distance between the second lens and the photosensitive surface; wherein the extended part drives the first lens and the second lens to move along the guide bar when the extended part rotates around the pivot part, for changing the first distance and the second distance; when the second lens moves along the guide bar for changing the second distance, the second lens drives the extended part to rotate around the pivot part, the first lens also driven to move along the guide bar, for changing the first distance.
