Abstract: A driving mechanism includes a frame, a carrying base, and a drive module. The carrying base is disposed in the frame, and includes a carrying body, a first stop element and a second stop element. The carrying body is configured to carry an optical element. The first stop element is disposed on the carrying body, and configured to limit the range of motion of the carrying body in a first direction. The second stop element is disposed on the carrying body, and configured to limit the range of motion of the carrying body in the first direction. The driving module is disposed in the frame, and configured to move the carrying body relative to the frame. The first direction is parallel to the axis of the optical element, and the first stop element is closer to the top portion of the frame than the second stop element.

Abstract: The disclosure provides an optical member driving mechanism including a movable portion, a fixed portion, a driving assembly and a circuit assembly. The movable portion is configured to connect an optical member with an optical axis. The fixed portion includes a base, wherein the movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The circuit assembly is electrically connected to the driving assembly and includes a circuit element, wherein the optical axis passes through an opening of the base, and the circuit element at least partially extends to the opening.
