Abstract
An optical element driving mechanism used for driving a first optical element is provided. The optical element driving mechanism includes a fixed portion and a first driving assembly. The first driving assembly is used for driving the first optical element to move relative to the fixed portion in a first dimension.
Claims18
An optical element driving mechanism used for driving an optical element, comprising:
- a fixed portion;
- a first driving assembly used for driving the optical element moving relative to the fixed portion in a first dimension;
- and
- a resilient assembly comprising:
- a first resilient portion;
- a second resilient portion;
- a third resilient portion;
- a first fixed end affixed on the optical element;
- a second fixed end affixed on the fixed portion;
- and
- an intermediate connecting portion between the first fixed end and the second fixed end, wherein the optical element is movably connected to the fixed portion through the resilient assembly,
- wherein:
- when viewed in a first direction, the first resilient portion has a plurality of bends, the third resilient portion has a plurality of bends, and the first resilient portion and the third resilient portion are mirror symmetrical with respect to a second axis;
- a number of bends of the second resilient portion is less than a number of bends of the first resilient portion;
- junctions between the first resilient portion and the second fixed end, between the first resilient portion and the intermediate connecting portion, between the second resilient portion and the intermediate connecting portion, and between the second resilient portion and the first fixed end are arranged along a straight line;
- the straight line is parallel to a first axis;
- and
- the first resilient portion and the third resilient portion are arranged along the first axis.
