    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism has a main axis, and includes a fixed portion, a movable portion, and a driving assembly. The fixed portion includes a housing, a base, and a frame. The base is fixedly connected to the housing along the main axis. The frame is disposed in the housing, and has a plurality of protruding columns extending along the main axis. The protruding columns have a first section and a second section, and the first section is closer to the base than the second section. The movable portion is movable relative to the fixed portion, and carries an optical element. The shortest distance between the first section and the movable portion is longer than the shortest distance between the second section and the movable portion. The driving assembly drives the movable portion to move relative to the fixed portion.

    Abstract: The present invention provides an optical element driving mechanism. The optical element driving mechanism includes a fixed part, a movable part and a driving assembly. The movable part is movably connected to the fixed part. The movable part includes a holder and a holder stopper. The holder carries the optical element. The holder includes a surface, a sidewall and a holder groove. The sidewall faces the optical element. The holder groove is disposed at the junction of the surface and the sidewall. The holder stopper protrudes from the surface along an optical axis of the optical element to limit a range of motion of the holder. The driving assembly drives the movable part to move relative to the fixed part.

    Abstract: A driving mechanism is provided, including a base unit, a frame, a holder, a first driving assembly, a sensing magnet, and a magnetic field sensor. The base unit has a polygonal structure. The frame is connected to the base unit. The holder is connected to the frame for holding an optical element, wherein the optical element defines an optical axis. The first driving assembly is disposed on the base unit and the frame, close to a first side of the base unit for driving the holder and the frame to move relative to the base unit along a horizontal direction perpendicular to the optical axis. The sensing magnet is disposed on the holder and close to a second side of the base unit, opposite to the first side. The magnetic field sensor is disposed on the base unit for sensing the sensing magnet.
