1. An optical element drive mechanism, comprising:
an immovable part;
a first movable part connected to a first optical element, wherein the first movable part is movable relative to the immovable part;
a second movable part connected to a second optical element that comprises an optical axis;
a third movable part connected to a third optical element;
a first drive assembly driving the first movable part to move relative to the immovable part;
a second drive assembly driving the second movable part to move relative to the immovable part along the optical axis; and
a third drive assembly driving the third movable part to move relative to the immovable part along a first axis and a second axis, wherein the first axis and the second axis are perpendicular to the optical axis;
wherein the optical element drive mechanism is polygonal, comprising a first side, a second side, a third side, and a fourth side;
wherein the first side is opposite and parallel with the third side, and the second side is opposite and parallel with the fourth side;
wherein the first drive assembly is disposed on the first side;
wherein the immovable part comprises a frame disposed above the third movable part, and the second movable part is disposed in the frame;
wherein the third drive assembly comprises a first axis drive assembly, and the first axis drive assembly comprises:
a first axis magnetic element disposed in the frame; and
a first axis coil disposed on the third movable part, wherein the first axis magnetic element corresponds to the first axis coil to generate a first axis driving force, and the first axis driving force drives the third movable part to move relative to the immovable part along the first axis.
