Optical element driving mechanism

An optical element driving mechanism for accommodating a first optical element and comprising:

• a fixed assembly:
• a movable part, configured to be connected to a second optical element, wherein the second optical element corresponds to the first optical element and defines an optical axis, and the movable part is movable relative to the fixed assembly;
• and
• a driving assembly, configured to drive the movable part to move relative to the fixed assembly;
• wherein the fixed assembly includes a first accommodation space configured to accommodate the first optical element;
• wherein the movable part further includes a first side wall, a second side wall and a rear side wall which is connected between the first side wall and the second side wall;
• wherein the driving assembly includes a first driving element, a second driving element, and a third driving element;
• wherein a first accommodation perforation and a second accommodation perforation are respectively formed on the first side wall and the second side wall;
• a third accommodation perforation is formed on the rear side wall;
• the first accommodation perforation, the second accommodation perforation and the third accommodation perforation respectively correspond to the first driving element, the second driving element and the third driving element;
• when viewed along a second axis that is perpendicular to the optical axis, the first driving element and the second driving element are respectively exposed from the first accommodation perforation and the second accommodation perforation;
• when viewed along the optical axis, the third driving element is exposed from the third accommodation perforation.
