Abstract
An optical element driving mechanism has an optical axis, and includes a fixed portion, a movable element, a plurality of blades, and a driving assembly. The fixed portion has an opening. The movable element is movable relative to the fixed portion. The blades are connected to the movable element. The driving assembly drives the movable element to move relative to the fixed portion. The driving assembly drives the movable element to change an overlap area of the blade and the opening.
Claims22
An optical element driving mechanism, having an optical axis, comprising:
- a fixed portion, having an opening;
- a movable element, which is movable relative to the fixed portion, having a plurality of tooth-shaped portions and a first accommodating portion;
- a plurality of blades, connected to the tooth-shaped portions of the movable element;
- a driving assembly, driving the movable element to move relative to the fixed portion;
- and
- a stopping element, connected to the fixed portion, wherein the first accommodating portion accommodates a part of the stopping element,
- wherein the movable element is driven by the driving assembly to change an overlapping area of the blades and the opening.
An optical element driving mechanism, having an optical axis, comprising:
- a fixed portion, comprising:
- a upper cover having an opening;
- and
- a base, disposed along a direction that is parallel to the optical axis with the upper cover, having a plurality of concave portions,
- a movable element, which is movable relative to the fixed portion;
- a stopping element, connected to the fixed portion;
- a plurality of blades, connected to the movable element;
- and
- a driving assembly, driving the movable element to move relative to the fixed portion;
- wherein the movable element is driven by the driving assembly to change an overlapping area of the blades and the opening,
- wherein one of the concave portions accommodates at least a part of the stopping element and penetrates through the base.
An optical element driving mechanism, having an optical axis, comprising:
- a fixed portion, having an opening
- a upper cover having an opening;
- and
- a base, disposed along a direction that is parallel to the optical axis with the upper cover,
- a movable element, which is movable relative to the fixed portion, comprising:
- a plurality of first protruding portions, extending toward the upper cover along a direction that is parallel to the optical axis;
- a plurality of second protruding portions, extending away from the opening along a direction that is perpendicular to the optical axis;
- a stopping element, connected to the fixed portion;
- a plurality of blades, connected to the movable element;
- and
- a driving assembly, driving the movable element to move relative to the fixed portion;
- wherein the movable element is driven by the driving assembly to change an overlapping area of the blades and the opening,
- wherein each second protruding portion has a first side and a second side, and the first side and the second side are contactable to the stopping element.
