Optical driving mechanism

An optical driving mechanism, configured to drive an optical element, comprising:

• a fixed portion, including a base, wherein the base has a central axis;
• a movable portion, configured to sustain the optical element, and the movable portion is movable relative to the fixed portion;
• a frame assembly, connected to the fixed portion and the movable portion and including a plurality of string arms, wherein the string arms form two V-shaped structures, and the V-shaped structures form a parallelogram structure;
• and
• a biasing element, including two ends, wherein the biasing element is disposed on the frame assembly and configured to force the movable portion to move relative to the fixed portion along the direction of the central axis, wherein the string arms enclose the biasing element, and the two ends of the biasing element are respectively connected to end portions of the V-shaped structure, and the end portions of the V-shaped structures are electrically connected to each other via the biasing element.
