Abstract
An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed assembly, a movable part, and a driving assembly. The movable part is movable relative to the fixed assembly. The driving assembly is configured to drive the movable part to move relative to the fixed assembly. The optical element driving mechanism further includes a holding assembly, and the driving assembly drives the movable part to move relative to the fixed assembly by the holding assembly.
Claims20
An optical element driving mechanism, comprising:
- a fixed assembly;
- a movable part, wherein the movable part is movable relative to the fixed assembly;
- and
- a driving assembly, configured to drive the movable part to move relative to the fixed assembly;
- wherein the optical element driving mechanism further comprises a holding assembly, and the driving assembly drives the movable part to move relative to the fixed assembly by the holding assembly;
- wherein the driving assembly comprises a counterweight, a piezoelectric element and a driving member, the piezoelectric element is connected to the counterweight, and the driving member is connected to the piezoelectric element;
- wherein the holding assembly is disposed on the driving member;
- wherein the holding assembly has a plate-shaped structure;
- wherein the holding assembly comprises a bottom plate, a first side plate and a second side plate;
- wherein the bottom plate has a flat plate-shaped structure;
- wherein the first side plate is bent from the bottom plate and extends from the bottom plate toward the second side plate;
- wherein the second side plate is bent from the bottom plate and extends from the bottom plate toward the first side plate;
- wherein the bottom plate, the first side plate and the second side plate are integrally formed as one piece;
- wherein the driving member has a long strip-shaped structure, and extends along a first axis;
- wherein when viewed along the first axis, the movable part does not overlap with the holding assembly;
- wherein when viewed along a second axis, the movable part does not overlap with the holding assembly;
- wherein when viewed along a third axis, the movable part partially overlaps with the holding assembly;
- wherein the first axis, the second axis, and the third axis are perpendicular to each other;
- wherein the first side plate and the second side plate are formed by bending opposite ends of the bottom plate toward each other, and
- wherein the bottom plate, the first side plate and the second side plate are formed from a single continuous sheet material.
