Abstract
An optical driving mechanism is provided. The optical driving mechanism includes a first movable part, a fixed part, and a first driving assembly. The first movable part is connected with an optical element. The first movable part is movable relative to the fixed part. The first driving assembly drives the first movable part to move relative to the fixed part. The fixing part has an opening.
Claims17
An optical driving mechanism, comprising:
- a first movable part connected to an optical element;
- a fixed part, wherein the first movable part is movable relative to the fixed part;
- a second movable part, wherein the second movable part moves relative to the fixed part;
- a first driving assembly driving the first movable part to move relative to the fixed part;
- a second driving assembly;
- a magnet disposed in the first movable part;
- and
- a locking element disposed in the fixed part, wherein:
- the fixed part has an opening for the light to pass through;
- the opening corresponds to an optical module, wherein the opening and the optical module are aligned on an optical axis where the light passes through;
- when viewed along the optical axis, the opening is between the first driving assembly and the second driving assembly, and the opening does not overlap with the first driving assembly and the second driving assembly;
- and
- the optical element connects the first movable part and the second movable part;
- the first driving assembly includes a first coil;
- and
- the distance between the magnet and the first coil is different from the distance between the second movable part and the locking element.
