Abstract

A camera module including a lens unit configured to move in a direction of an optical axis and a direction perpendicular with respect to the optical axis; a housing unit accommodating the lens unit; and a shock absorbing member disposed between the housing unit and the lens unit to reduce impacts and noise generated when the housing unit and the lens unit collide.

First claim

What is claimed is:

1. A camera module comprising:
an actuator, comprising magnets and coils configured to transfer driving force in different directions;
a housing accommodating the actuator;
a first frame accommodated in the housing and configured to be movable in the housing in an optical axis direction;
a second frame and a third frame accommodated in the first frame and configured to be movable in the optical axis direction, together with the first frame;
a lens barrel attached to the third frame;
a cover member attached to the first frame; and
a shock absorbing member formed in the cover member and configured to be elastically deformed,
wherein the second frame and the third frame are configured to be movable in the first frame in a first direction perpendicular to the optical axis direction, and
wherein the third frame is configured to be movable in the first frame in a second direction perpendicular to both the optical axis direction and the first direction.

2. The camera module of claim 1 , further comprising: a yoke mounted in the first frame to allow magnetic attraction to act between the yoke and at least one magnet among the magnets in the optical axis direction.

3. The camera module of claim 1 , wherein the shock absorbing member is protruded from the cover member upwardly and downwardly in the optical axis direction.

4. The camera module of claim 1 , wherein the shock absorbing member comprises:
a fixing part inserted into the cover member; and
a modification part configured to be elastically deformed by impacts.

5. The camera module of claim 1 , wherein the shock absorbing member is formed in each edge area of the cover member.
