Abstract: An optical element driving mechanism is provided, including a base, a holder movably coupled to the base for holding an optical element, a casing, a frame, a driving assembly, and an adhering member. The casing has a top wall and a plurality of side walls extending from the edge of the top wall along an optical axis of the optical element, and the top wall is closer to a light-incident end than the base. The frame is disposed on the top wall and has a frame protrusion extending toward the base. The driving assembly is configured to drive the holder to move relative to the base, and an accommodating space is formed between the base, the frame and the casing. The adhering member is disposed in the accommodating space and configured to directly adhere to the base, the frame, the casing, and the driving assembly.

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 is provided, including a housing, a hollow frame, a holder, and a driving assembly. The frame is fixed to the housing and has a stop surface. The holder is movably disposed in the housing for holding the optical element. The driving assembly is disposed in the housing to drive the holder and the optical element moving along the optical axis of the optical element relative to the frame. Specifically, the stop surface is parallel to the optical axis to contact the holder and restrict the holder in a limit position.

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.
