Abstract: A lens driving module is configured to provide an imaging lens system with auto-focus functionality. The imaging lens system is disposed between a preloading element and a driving base of the lens driving module. The preloading element includes an injection molded part and a ferromagnetic part partially embedded in the injection molded part. A rollable element is disposed in each of mounting structures of the injection molded part and in contact with a displaceable lens carrier of the imaging lens system. The ferromagnetic part and a magnet disposed on the displaceable lens carrier together generate a magnetic attraction force, such that the displaceable lens carrier exerts a preloading force on the rollable element. The driving base includes a driving coil and an electrical wiring pattern. The driving coil corresponds to the magnet for generating a driving force to drive the displaceable lens carrier to move along the optical axis.

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.
