Abstract
An optical member driving mechanism is provided, including a first movable portion, a fixed portion, and a first driving assembly. The first movable portion is connected to an optical member. The first movable portion is movable relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion.
Claims20
An optical member driving mechanism, comprising:
- a first movable portion, configured to connect an optical member, wherein light enters the optical member from an incident surface of the optical member along an incident direction;
- a fixed portion, wherein the first movable portion can move relative to the fixed portion;
- a first driving assembly, configured to drive the first movable portion to move relative to the fixed portion and comprising a pair of coils, wherein a winding axis of each of the coils is parallel to the incident direction;
- a guiding slot, having an arc structure and formed on a surface of the fixed portion that is parallel to the incident surface;
- and
- at least three guiding elements, disposed between the coils and engaged with the guiding slot, wherein the guiding elements are separated from each other, and the coils and the guiding elements are disposed on a same side of the first movable portion,
- wherein as seen from the incident direction, the first movable portion has a plurality of depressions for accommodating the guiding elements, and dimensions of each of the depressions are substantially the same as dimensions of each of the guiding elements.
