1. An optical element driving mechanism, comprising:
a fixed assembly, including a side wall;
a movable assembly, including a first movable part and a second movable part, configured to be connected to an optical element, wherein the movable assembly is movable relative to the fixed assembly; and
a first driving assembly, configured to drive the movable assembly to move relative to the fixed assembly;
wherein the optical element driving mechanism further comprises a first opening, and an external light beam travels along a first axis to pass through the first opening;
the first movable part has a first ring structure, forming a second opening;
the first ring structure surrounds the side wall;
the second movable part has a second ring structure, forming a third opening;
the second movable part further has a first protruding portion extending from the second ring structure toward the side wall; and
when viewed along the first axis, a portion of the first protruding portion does not overlap the first movable part.
