    摘要: An optical element driving mechanism having an optical axis includes a fixed portion, a movable portion, and a driving assembly. The movable portion is connected to the fixed portion. The driving assembly drives the movable portion to move in a direction that is parallel to the optical axis relative to the fixed portion, when viewed in the direction that is parallel to the optical axis, the optical element driving mechanism is a rectangular structure with a first side, a second side, a third side, and a fourth side, the first side and the third side are opposite, and the first side is adjacent to the second side and the fourth side.

    摘要: A driving mechanism is provided and includes a holder, a frame, a resilient element and a first driving assembly. The holder includes a first holder surface for holding an optical element having an optical axis. The frame is movably connected to the holder and includes a first frame surface. The holder is movably connected to the frame through the first resilient element. The first driving assembly is adjacent to the holder and is used for driving the holder to move relative to the frame, wherein both the first holder surface and the first frame surface face the first resilient element and do not contact the first resilient element, and the shortest distance between the first holder surface and the first resilient element is different than the shortest distance between the first frame surface and the first resilient element.

    摘要: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, and a driving assembly. The fixed part includes a bottom. The movable part moves relative to the fixed part and holds an optical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The bottom includes a base and an embedded assembly. A portion of the embedded assembly is embedded in the base. The embedded assembly includes a circuit member and a strengthening frame with a plate structure. The strengthening frame includes a perforation. The optical axis passes through the perforation.

    摘要: An optical element driving mechanism is provided, including a fixed part, a movable part and a driving assembly. The fixed part has a main axis, includes an outer frame and a base. The outer frame has a top surface and a sidewall. The top surface intersects the main axis. The sidewall extends from the edge of the top surface along the main axis. The base includes a base plate intersecting the main axis and securely connected to the outer frame. The movable part moves relative to the fixed part, and connects to an optical element having an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The main axis is not parallel to the optical axis.

    摘要: An optical element driving mechanism is provided. The optical element driving mechanism includes an immovable part, a movable part, a driving assembly, and a sensing assembly. The movable part is connected to an optical element including an optical axis. The movable part is movable relative to the immovable part. The driving assembly drives the movable part to move relative to the immovable part. The sensing assembly senses the movement of the movable part relative to the immovable part.
