Camera module having a moving frame

摘要

A camera module includes a lens barrel including at least one lens group; a moving frame that includes the lens barrel and moves in an optical axis direction and in a first direction and a second direction that are perpendicular to the optical axis direction; a fixed frame that movably supports the moving frame and provides the moving frame with a driving force in the optical axis direction, a driving force in the first direction, and a driving force in the second direction; and a base that fixes the fixed frame and includes an image sensor that is spaced apart from the at least one lens group in the optical axis direction.

1. A camera module comprising:
a lens barrel including at least one lens group; a moving frame that mounts the lens barrel and is movable in an optical axis direction, and in a first direction and a second direction that are perpendicular to the optical axis direction; a fixed frame that movably supports the moving frame and provides the moving frame with a driving force:
in the optical axis direction;in the first direction; andin the second direction,wherein the fixed frame comprises a plurality of sidewalls that surround side portions of the moving frame; a printed circuit board disposed on a sidewall of the plurality of sidewalls, wherein the printed circuit board provides current to the fixed frame; and a base that fixes the fixed frame and comprises an image sensor that is spaced apart from the at least one lens group in the optical axis direction; wherein the fixed frame further comprises:
a first driving coil for moving the moving frame in the optical axis direction;a second driving coil for moving the moving frame in the first direction; andthird driving coils for moving the moving frame in the second direction.
