Optical element driving mechanism

An optical element driving mechanism, comprising:

• a body;
• a fixed portion;
• a movable portion, being movable relative to the fixed portion;
• a connecting element, connecting the fixed portion to the movable portion, and providing the movable portion with restoring force for moving relative to the fixed portion;
• a first driving assembly, driving the movable portion to perform a first motion relative to the fixed portion, disposed on a first side of the body;
• a third driving assembly, driving the movable portion to perform a second motion relative to the fixed portion, disposed on a second side of the body that is parallel to the first side;
• an optical element, connected to the movable portion, including an incident surface and an emissive surface, wherein the incident surface is orthogonal to the emissive surface;
• and
• a fulcrum element, wherein a position of the fulcrum element is close to a center of mass of the first driving assembly, the third driving assembly, and the movable portion;
• wherein the first side is not parallel to the incident surface or the emissive surface;
• and
• wherein the connecting element and the fulcrum element do not overlap when viewed along a third direction that is perpendicular to the emissive surface;
• wherein the connecting element and the fulcrum element do not overlap when viewed along a second direction that is perpendicular to the incident surface;
• and
• wherein the second direction is perpendicular to the third direction.
