LENS DRIVING APPARATUS AND CAMERA MODULE

WIPO Patent Application WO/2022/257714

A1

Disclosed are a lens driving apparatus and a camera module. The lens driving apparatus comprises a mobile carrier, a fixed base, a driving mechanism, a guide groove, a supporting mechanism, and a magnetic attraction member. The mobile carrier is used to accommodate a lens assembly, and the fixed base and the mobile carrier are arranged opposite to each other at an interval along the optical axis direction. The driving mechanism is located on the circumferential side of the mobile carrier, and the driving mechanism comprises at least one set of coils and at least one set of magnets. The guide groove is arranged between the fixed base and the mobile carrier, the supporting mechanism is movably arranged in the guide groove, and the magnetic attraction member is mounted on the fixed base and arranged opposite to the magnets, so that a magnetic attraction force along the optical axis direction is generated between the magnetic attraction member and the magnets. Therefore, the structure of the lens driving apparatus is simple, which implements an AF function of a lens in the optical axis direction and an OIS function of an optical axis orthogonal surface while ensuring the miniaturization of the camera module.
