Abstract: An optical element driving mechanism includes a movable assembly, a fixed assembly, and a driving assembly. The movable assembly is configured to be connected to an optical element. The movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly in a range of motion. The optical element driving mechanism further includes a positioning assembly configured to position the movable assembly at a predetermined position relative to the fixed assembly when the driving assembly is not operating.

Abstract: An optical element driving mechanism for corresponding to an optical module, the optical element driving mechanism including a fixed portion, a movable portion, and a first driving assembly. The fixed portion has an aperture. The movable portion is for connecting to an optical element and is movable relative to the fixed portion. The first driving assembly is for driving the movable portion to move relative to the fixed portion. The fixed portion has an elongated structure, and the fixed portion further comprises a first end. The fixed portion further comprising a second end, wherein the first end and the second end are arranged along a first direction. A shortest distance between the optical sensing element and the first end is shorter than a shortest distance between the optical sensing element and the second end.

Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first blade, a transmission assembly, and a driving assembly. The first blade is movable relative to the fixed portion. The transmission assembly is movable relative to the fixed portion. The driving assembly is used for driving the transmission element to move relative to the fixed portion. The transmission element brings the first blade to move relative to the fixed portion when the transmission element is driven by the driving assembly.
