Lens driving device and camera assembly

Abstract

A lens driving device includes a base, an AF movable part movably disposed on the base, and a lens mount movably disposed on the AF movable part. The AF movable part includes an AF frame and multiple horizontal suspension wires. The AF frame is movably disposed on the base. An end of each horizontal suspension wire is connected to the AF frame, and another end of each horizontal suspension wire is connected to the base. The lens mount is movably disposed on the AF frame. The lens driving device is free of a spring plate. This device employs the horizontal suspension wires as an AF suspension architecture to achieve a friction-free design, uses a first rolling element and two second rolling elements as an OIS guiding architecture, and uses the horizontal suspension wires as power and signal traces to achieve electrical connection with the base, simplifying an overall structure.
