Abstract
A driving mechanism for moving an optical element is provided. The driving mechanism includes a fixed part, a movable part, and a driving assembly. The movable part is movably connected to the fixed part for holding the optical element. The driving assembly is configured for moving the movable part relative to the fixed part.
Claims20
A driving mechanism for moving an optical element, comprising:
- a fixed part;
- a movable part, movably connected to the fixed part for holding the optical element;
- a driving assembly, configured for moving the movable part relative to the fixed part, wherein the driving assembly includes a first driving element that drives the movable part to rotate relative to the fixed part around a first axis;
- and
- a sensor, wherein the sensor and the first driving element are disposed on the fixed part, and when viewed in a reference direction, the first driving element and the sensor at least partially overlap,
- wherein the fixed part includes a base and a plate member connected to the base, and a cavity and a protrusion are formed on an inner surface of the plate member, wherein the first driving element is disposed on a bottom surface of the cavity, and the sensor is disposed on a top surface of the protrusion, wherein the bottom surface and the top surface are parallel to the reference direction, and the first driving element and the sensor do not protrude from the inner surface of the plate member.
