Abstract
A driving mechanism for an optical element is provided, including a fixed portion, a movable portion, a first driving assembly, and a positioning assembly. The movable portion is movably disposed on the fixed portion, and includes an optical element. The first driving assembly is at least partially disposed on the fixed portion, and drives the optical element to move in a first direction. The positioning assembly is disposed on the fixed portion or the movable portion, wherein the positioning assembly limits the movable part to a first terminal position or a second terminal position relative to the fixed portion.
Claims20
An optical element driving mechanism fir corresponding to an optical sensing element, comprising:
- a fixed portion, having an aperture corresponding to the optical sensing element, wherein an optical axis that is perpendicular to the optical sensing surface of the optical sensing element passes through the aperture;
- a movable portion, for connecting to an optical element and being movable relative to the fixed portion, wherein when viewed along the optical axis, the optical element overlaps the aperture when the movable portion is located at a first terminal position;
- and
- a first driving assembly, for driving the movable portion to move relative to the fixed portion;
- wherein the fixed portion has an elongated structure that extends along a first as direction, and the aperture is located at a first end of the fixed portion when viewed along the optical axis.
