The plastic carrier includes an inner portion and an outer portion, wherein an inner space is defined by the inner portion, and the outer portion includes at least one mounting structure. The imaging lens assembly is disposed in the inner space of the plastic carrier. The reflective element is for folding an image light by a reflective surface of the reflective element into the imaging lens assembly. The auto-focusing elements include at least two magnets and at least one wiring element, wherein the auto-focusing elements are for moving the plastic carrier along a second optical axis of the imaging lens assembly, and the magnets or the wiring element can be disposed on the mounting structure of the outer portion.

Abstract: A camera driving module includes: a base including a central opening; a casing disposed on the base and including an opening hole corresponding to the central opening; a lens unit movably disposed on the casing; and a focus driving part. The focus driving part includes a carrier, an AF coil element, at least two permanent magnets and a Hall element. The carrier is disposed on the lens unit and movable in a direction parallel to an optical axis. The AF coil element is fixed to the base and faces toward the carrier. The permanent magnets are fixed on one side of the carrier facing toward the base and disposed opposite to each other about the optical axis. The Hall element faces toward a corresponding surface of one of the permanent magnets. The AF coil element and the corresponding surfaces are arranged in the direction parallel to the optical axis.

Abstract: A lens assembly driving module includes a base, a cover, a lens carrier and a damping agent. The cover is coupled to the base. The lens carrier is integrally formed with a plastic barrel into a coaxial unitary element which has an internal space for receiving at least one optical lens element and includes at least two protrusion portions located on one end of the coaxial unitary element close to the base. The damping agent is filled between the base and each of the protrusion portions. The protrusion portions are a part of the coaxial unitary element, and a distance in a direction perpendicular to an optical axis between the part of the coaxial unitary element and the internal space is a maximum distance among distances in the direction perpendicular to the optical axis between other parts of the coaxial unitary element and the internal space.

Abstract: An imaging lens module includes an imaging lens unit, an optical folding component and a sensing magnet group. The imaging lens unit has an optical axis. The optical folding component is configured to fold an incident optical path into the imaging lens unit to coincide with the optical axis. The sensing magnet group includes two sensing magnets that are sequentially disposed on the imaging lens unit along a direction in parallel with the optical axis. The sensing magnets are located at the same side with respect to a reference plane that passes through the optical axis and has a normal direction perpendicular to the optical axis. When the sensing magnets are observed from the direction in parallel with the optical axis, images of the sensing magnets are at least partially overlapped. Two adjacent magnetic poles of the sensing magnets are like poles between which there is a repulsive force.

Abstract: A camera module includes a base, a lens module, a reflection module, a longitudinal guiding bar, a transverse guiding bar and a shaft guiding bar. The lens module has an optical axis and is disposed on the base. The reflection module includes a reflective element disposed on the base and located on an object side of the lens module. The longitudinal and transverse guiding bars are disposed between the base and the lens module and respectively extend in a first direction parallel to the optical axis and a second direction perpendicular to the optical axis. The shaft guiding bar is disposed between the base and the reflection module and extends in the second direction. The lens module is movable along the longitudinal and transverse guiding bars, respectively, and the reflective element is rotatable by taking the shaft guiding bar as a rotation axis.
