1. An optical component driving mechanism, comprising:
a first movable portion connected to an optical component;
a fixed portion having an opening, wherein the first movable portion is movable relative to the fixed portion;
a first driving assembly configured to drive the first movable portion to perform a first movement relative to the fixed portion; and
a limiting assembly limiting the range of motion of the first movable portion;
wherein the optical component overlaps the opening when the first movable portion is located in a first position;
wherein the limiting assembly comprises:
a first locking structure corresponding to a second locking structure, wherein the first locking structure limits the first movable portion in the first position when the first driving assembly drives the first movable portion to move;
a second movable portion, wherein the first locking structure is formed on the second movable portion; and
a second driving assembly configured to drive the second movable portion to perform a second movement relative to the fixed portion;
wherein the first movement is different from the second movement, and the second movement is rotation with a rotational axis as an axle center;
wherein the first locking structure has an elongated structure extending along a long axis, the first locking structure and the second locking structure are fixedly disposed on the second movable portion and the first movable portion respectively, and the long axis is perpendicular to the rotational axis;
wherein the rotational axis is parallel to a first axis; and the first movement is movement along a second axis, wherein the second axis is perpendicular to the first axis;
wherein the first locking structure comprises:
a body having an elongated structure extending along the long axis;
a first locking portion having a curved structure, located in a first end of the body, and corresponding to a first abutting portion of the second locking structure, wherein the first abutting portion has a curved structure;
a second locking portion having a curved structure, located in a second end of the body, and corresponding to a second abutting portion of the second locking structure, wherein the second abutting portion has a curved structure;
a first guiding portion having a planar structure, wherein the first guiding portion is adjacent to the first locking portion, and the first guiding portion forms a discontinuous surface with the first locking portion, and the first guiding portion guides the second locking structure to move relative to the first locking structure when the first locking structure is movable relative to the second locking structure;
a second guiding portion having a planar structure, wherein the second guiding portion is adjacent to the first locking portion, and the second guiding portion forms a discontinuous surface with the first locking portion, wherein the first locking portion is located between the first guiding portion and the second guiding portion, and the second guiding portion guides the second locking structure to move relative to the first locking structure when the first locking structure is movable relative to the second locking structure;
a third guiding portion having a planar structure, wherein the third guiding portion is adjacent to the second locking portion, and the third guiding portion forms a discontinuous surface with the second locking portion, and the third guiding portion guides the second locking structure to move relative to the first locking structure when the first locking structure is movable relative to the second locking structure; and
a fourth guiding portion having a planar structure, wherein the fourth guiding portion is adjacent to the second locking portion, and the fourth guiding portion forms a discontinuous surface with the second locking portion, wherein the second locking portion is located between the third guiding portion and the fourth guiding portion, and the fourth guiding portion guides the second locking structure to move relative to the first locking structure when the first locking structure is movable relative to the second locking structure.
