Optical element driving mechanism

An optical element driving mechanism, comprising:

• a fixed portion;
• a movable portion, movable relative to the fixed portion, wherein the movable portion comprises:
• a first movable assembly connected to a first optical element;
• a second movable assembly connected to a second optical element;
• a first coil disposed at the first movable assembly;
• and
• a second coil disposed at the second movable assembly;
• a first resilient element electrically connected to the first movable assembly;
• a second resilient element electrically connected to the second movable assembly;
• a third resilient element electrically connected to the first movable assembly;
• and
• a fourth resilient element electrically connected to the second movable assembly,
• wherein the first movable assembly is movable relative to the second movable assembly;
• wherein the fixed portion comprises:
• a first guiding element with a first axis, guiding the first movable assembly and the second movable assembly to move in a first dimension;
• a second guiding element with a second axis, guiding the first movable assembly and the second movable assembly to move in the first dimension;
• and
• a first magnetic element, corresponding to the first coil and generating a first driving force, and corresponding to the second coil and generating a second driving force;
• wherein the first magnetic element corresponds to the first coil and the second coil simultaneously;
• and the first magnetic element has a first surface facing the first coil and the second coil;
• wherein a line connecting the first axis and the second axis intersects the first optical element when viewed along an optical axis of the first optical element;
• wherein the fixed portion has a polygonal structure when viewed along the optical axis, and the first guiding element and the second guiding element are located at opposite corners of the fixed portion;
• wherein the greatest length of the first coil is different from the greatest length of the second coil when viewed in a direction parallel to the first surface;
• and
• wherein the first guiding element passes through the first resilient element and the second resilient element, and the second guiding element passes through the third resilient element and the fourth resilient element.
