Abstract: A lens driving mechanism is provided, configured to drive an optical lens, including a bottom plate, a movable portion, an elastic member, and a biasing assembly. The movable portion is disposed on the bottom plate and has a base and a holder, wherein the holder is configured to hold the optical lens, and the holder is movably connected to the base. The elastic member connects the movable portion to the bottom plate. The biasing assembly connects the bottom plate and the movable portion and is configured to force the movable portion to move relative to the bottom plate. When the holder moves to a lower-limit position relative to the base, the holder comes into contact with the elastic member.

Abstract: A lens driving module for holding and moving a lens is provided, including a lens holder having an accommodating space, a driving coil, a plurality of first magnetic members having a longitudinal structure, a virtual plane, and a plurality of second magnetic members, wherein the lens is disposed in the accommodating space. The lens holder is disposed between the first magnetic members and between the second magnetic members. The driving coil is disposed on the lens holder and surrounds the accommodating space. The virtual plane is perpendicular to a longitudinal axis of the longitudinal structure. The projections of the driving coil and the first magnetic members on the virtual plane along the longitudinal axis of the longitudinal structure overlap each other. When a first current flows through the driving coil, the lens holder moves relative to the first and second magnetic members along a first direction.
