Optical element driving mechanism

An optical element driving mechanism, comprising:

• a fixed part comprising a frame;
• a movable part, movable relative to the fixed part, the movable part holds an optical element having an optical axis;
• and
• a driving assembly, driving the movable part to move relative to the fixed part,
• wherein the driving assembly comprises a driving magnetic element and a driving coil, and the driving magnetic element corresponds to the driving coil,
• wherein the movable part comprises an optical element holder and a photosensitive element holder, the driving magnetic element comprises a first driving magnetic element and a second driving magnetic element, and the driving coil comprises an optical element holder driving coil, photosensitive element holder first driving coil and a photosensitive element holder second driving coil,
• wherein the optical element holder driving coil is disposed on the optical element holder and corresponds to the first driving magnetic element;
• wherein the driving assembly further comprises a first driving magnetic element conductive sheet,
• wherein the first driving magnetic element conductive sheet is disposed between the optical element holder driving coil and the optical element holder, and the optical element holder driving coil is fixedly disposed on the first driving magnetic element conductive sheet, and
• wherein the first driving magnetic element conductive sheet positionally corresponds to the first driving magnetic element;
• wherein the optical element holder comprises an optical element holder body and an optical element holder stopping element, the optical element holder stopping element extends from the optical element holder body toward the frame, and the optical element holder stopping element partially overlaps the frame when viewed along the optical axis,
• wherein along the optical axis, the shortest distance between the optical element holder stopping element and the frame is shorter than the shortest distance between the optical element holder body and the photosensitive element holder;
• wherein the optical element holder driving coil comprises a winding axis perpendicular to the optical axis,
• wherein the optical element holder driving coil partially overlaps with the optical element holder stopping element when viewed along a direction perpendicular to both the winding axis and the optical axis;
• wherein a driving assembly center of the driving assembly does not overlap an optical element driving mechanism center of the optical element driving mechanism when viewed along the optical axis;
• wherein the first driving magnetic element positionally corresponds to the optical element holder driving coil, the photosensitive element holder first driving coil and the photosensitive element holder second driving coil;
• wherein a shortest distance between the first driving magnetic element and the optical element holder is greater than a shortest distance between the second driving magnetic element and the optical element holder.
