Abstract: A driving mechanism for moving an optical element is provided, including a movable portion, a fixed portion, a driving assembly, and a first resilient element. The movable portion is for connecting the optical element. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The first resilient element has a board structure. The movable portion is movably connected to the fixed portion via the first resilient element. The fixed portion includes a connection surface, a restricting surface, and a recessed portion. At least a portion of the first resilient element is disposed on the connection surface. The restricting surface contacts and restricts the movable portion. The recessed portion is located between the connection surface and the restricting surface, wherein the recessed portion is lower than the connection surface and the restricting surface.

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.
