    Abstract: A lens driving module includes a base, a frame fixedly connected to the base, and a holder configured to connect an optical lens. The holder is movable relative to the base. The lens driving module also includes a reflecting element configured to reflect light from a light incident direction to a first direction. The first direction is perpendicular to the light incident direction, and the first direction is parallel to an optical axis of the optical lens. The lens driving module further includes a first electromagnetic driving assembly configured to force the holder to move along the first direction relative to the base. The lens driving module has multiple recesses formed on the base and arranged along the first direction. The lens driving module includes multiple the rolling elements disposed on the recesses, and the holder is moved relative to the base via the rolling elements.

    Abstract: An optical mechanism is provided for receiving a light that is reflected by a reflecting element. The optical mechanism includes a movable portion, a fixed portion, and a driving module. The movable portion is movable relative to the fixed portion for receiving an optical member that defines an optical axis. The driving module includes a first electromagnetic driving assembly and a second electromagnetic driving assembly for driving the movable portion to move relative to the fixed portion. The optical axis is located between the first electromagnetic driving assembly and second electromagnetic driving assembly when viewed from the optical axis, and the first electromagnetic driving assembly and the second electromagnetic driving assembly are electrically independent from each other.

    Abstract: A camera system including a telephoto lens module is provided. The telephoto lens module includes a first image sensor, a first assembly, and a second assembly. The first assembly includes a first driving mechanism and a reflecting member connected to the first driving mechanism. The first driving mechanism is configured to drive the reflecting member to rotate around a first axis and a second axis. The second assembly is disposed between the first assembly and the first image sensor, including a second driving mechanism and a first lens. The second driving mechanism is configured to drive the first lens to move along a third axis. The first, second, and third axes are not parallel to each other. When light enters the telephoto lens along the first axis, light is reflected by the reflecting member and through the first lens along the third axis to the first image sensor.

    Abstract: An optical element driving mechanism is provided in the present disclosure, including a first movable portion, a fixed portion, a first driving assembly and a first supporting assembly. The first movable portion is connected to a first optical element. The first movable portion is movable relative to the fixed portion. The first driving assembly drives the first movable portion to move relative to the fixed portion in a first dimension. The first supporting assembly is disposed between the first movable portion and the fixed portion. The first movable portion moves relative to the fixed portion via the first supporting assembly.

    Abstract: The present invention provides an optical element driving mechanism. The optical element driving mechanism includes a fixed part, a movable part and a driving assembly. The movable part is movably connected to the fixed part. The movable part includes a holder and a holder stopper. The holder carries the optical element. The holder includes a surface, a sidewall and a holder groove. The sidewall faces the optical element. The holder groove is disposed at the junction of the surface and the sidewall. The holder stopper protrudes from the surface along an optical axis of the optical element to limit a range of motion of the holder. The driving assembly drives the movable part to move relative to the fixed part.
