US 12,724,321 B2 · Camera module including aperture

Abstract

A camera module includes a lens assembly, at least two blades that are on a top surface of the lens assembly and define a lens light entrance hole, a moving drive magnet, a fixed drive magnet, a blade controller that is coupled to the moving drive magnet and to the at least two blades, where the blade controller is configured to control a movement of the at least two blades, a lens assembly body, where the lens assembly and the fixed drive magnet are on the lens assembly body, and a frame that at least partially surrounds the lens assembly body and includes a coil that faces the moving drive magnet, where the blade controller is configured to adjust a diameter of the lens light entrance hole by controlling the moving drive magnet to move based on a current applied to the coil.

A camera module comprising:

a lens assembly;
at least two blades that are on a top surface of the lens assembly and define a diameter of a lens light entrance hole;
a moving drive magnet;
a fixed drive magnet;
an aperture cover that is on top surfaces of the at least two blades and comprises a circular opening that overlaps the lens light entrance hole;
a blade controller comprising a connector portion that is connected to bottom surfaces of the at least two blades, wherein the blade controller comprises a slide part that accommodates the moving drive magnet, and wherein the blade controller is configured to adjust a length of the connector portion based on a movement of the moving drive magnet;
a first lens assembly body comprising a slide coupling area and a groove, wherein the slide coupling area is on a first side of the first lens assembly body that faces a first surface of the moving drive magnet and is coupled with the slide part, and wherein the groove accommodates the fixed drive magnet;
a second lens assembly body defining an opening on a first side of the second lens assembly body that faces the slide coupling area;
and
a frame comprising a coil on a first side that faces a second surface of the moving drive magnet that is opposite to the first surface of the moving drive magnet,
wherein the blade controller is configured to adjust a diameter of the lens light entrance hole by moving the moving drive magnet based on a current applied to the coil.
