Abstract
An auto-focus optical lens module is proposed, including a base body having a receiving space formed therein, a lens sleeve rotatably disposed in the receiving space, a lens screwed with the lens sleeve, and a piezoelectric element fixed in the base body for contacting and driving the lens sleeve to rotate, wherein the base body and the lens are respectively provided with a first and second guiding portions for slidably positioning, thereby driving the lens sleeve to rotate so as to enable the lens to focus. The auto-focus optical lens module has simplified elements and enhanced driving force.
