Optical element driving mechanism

An optical element driving mechanism, comprising:

• a first holder used for connecting to an optical element;
• a fixed portion, wherein the first holder is movable relative to the fixed portion, and the first holder and the fixed portion are arranged along a main axis;
• a first driving assembly used for driving the first holder to move relative to the fixed portion;
• a first stopping assembly used for restricting the movable range of the first holder relative to the fixed portion;
• a second holder used for connecting the optical element and is movable relative to the fixed portion and the first holder;
• a second driving assembly used for driving the second holder to move relative to the first holder;
• and
• a bottom affixed on the first holder,
• wherein:
• when viewed along a first axis perpendicular to the main axis, at least a portion of the bottom is between the first holder and the second holder;
• when viewed along the first axis, at least a portion of the second driving assembly is between the bottom and the first holder;
• and
• when viewed along the first axis, at least a portion of the second driving assembly is exposed from the bottom.
