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.

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: Provided is a lens assembly driving module including a photographing lens assembly, a first driving mechanism and a second driving mechanism. The photographing lens assembly includes N lens elements and has an optical axis passing through the N lens elements. The first driving mechanism drives at least N/2 said lens elements to move along the optical axis of the photographing lens assembly. The second driving mechanism enables a relative distance along the optical axis of two adjacent ones of the N lens elements to vary. Therefore, any specific one of the lens elements is capable of being driven to optimize optical imaging resolution of various fields of view independently within a real shot at different object distances.
