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: A reflection module capable of image stabilization includes a reflecting element, a rotatable holder, a fixed base, a spherical supporting structure, an auxiliary supporting structure and an image stabilizing actuator. The reflecting element having a reflecting surface for folding optical path of incident light is disposed on the rotatable holder. The fixed base is connected to the rotatable holder via an elastic element. The spherical supporting structure is disposed between the rotatable holder and the fixed base. The auxiliary supporting structure disposed on at least one of the rotatable holder and the fixed base and corresponds to the spherical supporting structure. At least part of the image stabilizing actuator is disposed on the rotatable holder for driving the rotatable holder to rotate by taking the spherical supporting structure as rotation center. The spherical supporting structure is a ball having at least three contact points with the auxiliary supporting structure.

Abstract: A camera module includes an imaging lens assembly having an optical axis and a driving device including a fixed component, a lens carrier, a magnet carrier, a first ball group, and a second ball group. The imaging lens assembly is disposed in the lens carrier. The magnet carrier has a first groove group extending parallel to the optical axis and a second groove group extending perpendicular to the optical axis. One of the fixed component and the lens carrier has a third groove group disposed opposite to the second groove group. The imaging lens assembly is movable with respect to the fixed component on a plane perpendicular to the optical axis via the second ball group disposed between the second groove group and the third groove group and along a direction parallel to the optical axis through the first ball group disposed in the first groove group.
