Abstract
An optical element driving mechanism is provided in the present disclosure, including a fixed portion, a movable portion that is connected to an optical assembly, and a driving assembly that drives the movable portion to move relative to the fixed portion and includes a piezoelectric element. The piezoelectric element includes a piezoelectric unit, a guiding element, and a counterweight element. A first end of the guiding element is connected to the piezoelectric unit, and a second end is connected to the fixed portion. The counterweight element is connected to the piezoelectric unit. The fixed portion comprises a bottom that has a first through hole and a second through hole. The first through hole corresponds to the piezoelectric unit and the counterweight element, accommodates a part of the piezoelectric unit and the counterweight element. The second through hole corresponds to the guiding element, accommodates the second end of the guiding element.
