US 12,607,922 B2 · Camera module and electronic device comprising same

Abstract

According to various embodiments, a camera module and/or an electronic device comprising same may comprise: a first guide unit comprising a first magnet having the shape of an arc around a first axis of rotation; a first rotating unit comprising a rotation base disposed on the first guide unit and configured to rotate around the first axis of rotation; a support bearing disposed between the first guide unit and the first rotating unit and configured to rotatably support the first rotating unit with regard to the first guide unit; a first coil disposed on the first rotating unit and configured to generate an electromagnetic force together with the first magnet in response to an electric signal applied thereto, thereby providing a driving force for rotating the first rotating unit; a fixed magnet disposed on one of the first guide unit and the first rotating unit; and a first yoke disposed on an other of the first guide unit and the first rotating unit. The first rotating unit may be configured to rotate while remaining forced against the support bearing by a magnetic force generated between the fixed magnet and the first yoke. The first coil may be configured to move along an arc trajectory on the first magnet as the first rotating unit rotates.

A camera module comprising:

a first guide unit including a first magnet having an arc shape centered on a first rotation axis;
a first rotating unit comprising a rotation base disposed on the first guide unit and configured to rotate around the first rotation axis;
a support bearing disposed between the first guide unit and the first rotating unit and configured to rotatably support the first rotating unit with respect to the first guide unit;
a first coil disposed on the first rotating unit and configured to provide a driving force to rotate the first rotating unit by receiving an electrical signal and generating an electromagnetic force together with the first magnet;
a fixed magnet disposed on any one of the first guide unit and the first rotating unit;
and
