    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: The present disclosure provides an optical system, including a first optical mechanism. The first optical mechanism includes a first movable part, a fixed assembly, a first driving assembly and a guiding assembly. The first movable part includes an optical element. The first movable part is movable relative to the fixed assembly. The first driving assembly is configured to drive the first movable part to move relative to the fixed assembly. The guiding assembly is configured to guide the first movable part to move relative to the fixed assembly. A friction force is generated between the first movable part and the guiding assembly, and the first movable part is temporarily positioned on the fixed assembly through the friction force.
