Abstract: An imaging lens module with auto focus function includes an imaging lens assembly, an electromagnetic driving component assembly and a lens carrier. The imaging lens assembly has an optical axis. The electromagnetic driving component assembly drives the imaging lens assembly to move in a direction parallel to the optical axis by a Lorentz force. The imaging lens assembly is mounted to the lens carrier such that the imaging lens assembly can be wholly driven by the Lorentz force. The lens carrier includes an object-side part, a mounting structure and a plurality of plate portions. The object-side part includes a tip-end minimal aperture configured for light to travel through; and a tapered surface which surrounds an area tapered off from image side to object side. The mounting structure and the plate portions are configured for at least a part of the electromagnetic driving component assembly to be mounted thereto.

Abstract: An actuator is configured to drive an imaging lens system. The actuator includes a frame portion configured to accommodate the imaging lens system, a supporting portion disposed on the frame portion, a driving portion configured to drive the imaging lens system to move, an optical mark structure disposed on part of the frame portion, the supporting portion or the driving portion and a liquid disposed on the optical mark structure. The supporting portion is configured to support the imaging lens system and give the imaging lens system a degree of freedom of movement with respect to the frame portion. The optical mark structure includes a plurality of optical mark units arranged side by side. The liquid is in physical contact with the imaging lens system, the frame portion, the supporting portion or the driving portion that is adjacent to the optical mark structure.

Abstract: An imaging lens driving module includes a lens carrier, a molded receiving base, a rolling element, a molded frame element and a driving mechanism. The lens carrier defines an optical axis. The molded receiving base is configured to receive the lens carrier. The rolling element is disposed between the lens carrier and the molded receiving base, and the lens carrier is allowed to be displaceable along the optical axis and relatively to the molded receiving base. The molded frame element is coupled with the molded receiving base for defining an inner space to receive the lens carrier. The driving mechanism drives the lens carrier displaceable along the optical axis, and includes a driving magnet and a driving coil, wherein the driving magnet is disposed on the lens carrier, the driving coil is corresponding to and faces towards the driving magnet.

Abstract: A lens driving module includes a base, a shield can, a driving mechanism, a space maintaining element and a damping element. The base has an opening. The shield can is coupled to the base and has a central aperture corresponding to the opening. The driving mechanism is disposed in the shield and configured to drive a lens unit to move. The space maintaining element is in physical contact with the shield can. The space maintaining element includes a plastic frame portion and a metal structure portion. The metal structure portion includes pins extending toward the base. The metal structure portion is insert-molded with the plastic frame portion to form the space maintaining element. The damping element is connected to the pins and the lens unit. The pins of the metal structure portion are located closer to the optical axis than part of the metal structure portion without the pins.
