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: An imaging camera driving module includes a lens unit, a driving mechanism, a sensing mechanism and an image surface. At least a part of the driving mechanism is coupled to the lens unit to drive the lens unit to move in a direction parallel to the optical axis. The sensing mechanism includes sensing magnets fixed to the lens unit and sensing elements not facing the driving mechanism. The sensing elements are disposed on an image side of the imaging lens assembly of the lens unit and corresponding to the sensing magnets. The sensing elements are configured to detect a relative position of the sensing magnets. The image surface is disposed on the image side of the imaging lens assembly, and the optical axis passes through the image surface. The sensing mechanism is configured to detect a tilt of the optical axis with respect to the central axis.

Abstract: An imaging lens driving module includes a base, a casing, a driving mechanism and a damping element. The base has an opening, and the casing has a central aperture corresponding to the opening. The casing includes a plastic frame portion and a metal structure portion. The plastic frame portion is coupled to the base. The metal structure portion has a plurality of pins extending towards the base. The driving mechanism is disposed in the casing. The driving mechanism is configured to drive the lens unit to move in a direction parallel to an optical axis. The damping element is connected to the pins and the lens unit. The metal structure portion is insert-molded with the plastic frame portion to form the casing. The pins are located closer to the optical axis than the other part of the metal structure portion to the optical axis.
