Abstract

A camera module is disclosed. In accordance with an embodiment of the present invention, the camera module includes a lens barrel, which supports a lens and in which the lens allows a ray of light to be incident at an imaging part, a driver, which moves the lens barrel along an optical axis, a body, which houses the lens barrel, and a buffering part, which is interposed between the lens barrel and the body when the lens barrel collides with the body.

Claims

1. A camera module comprising:

a lens barrel supporting a lens, the lens allowing a ray of light to be incident at an imaging part;

a driver configured to move the lens barrel along an optical axis;

a body housing the lens barrel; and

a buffering part interposed between the lens barrel and the body when the lens barrel collides with the body.

2. The camera module of claim 1, wherein the buffering part is protruded on at least one of the lens barrel and the body.

3. The camera module of claim 2, wherein the buffering part is protruded on an end part on a side of a moving direction of the lens barrel in such a way that the buffering part faces the body.

4. The camera module of claim 2, wherein the lens barrel further comprises a guide part protruded to guide a movement of the lens barrel, and

the buffering part is disposed on an end part of the guide part.

5. The camera module of claim 2, wherein the buffering part is formed on the body in such a way that the buffering part is protruded toward an end part on a side of a moving direction of the lens barrel.

6. The camera module of claim 5, wherein the body comprises a housing and a substrate, the housing covering the lens barrel, and

the buffering part is disposed on at least one of the housing and the substrate.

7. The camera module of claim 6, wherein the housing comprises a partition wall covering the lens barrel on the side of the moving direction of the lens barrel, and

the buffering part is disposed on the partition wall in such a way that the buffering part faces the lens barrel.

8. The camera module of claim 2, wherein the buffering part is made of an elastic body.

9. The camera module of claim 8, wherein the buffering part is made of a material comprising at least one of rubber, silicon and silicon rubber.

10. The camera module of claim 2, wherein the buffering part is formed by being coated or adhered to the lens barrel or the body.

11. The camera module of claim 1, the buffering part comprises a plate-shaped buffering pad interposed between the lens barrel and the body.

12. The camera module of claim 11, the body comprises a housing covering the lens barrel, and

the buffering pad is adhered to a surface of the housing, the surface facing the lens barrel.

13. The camera module of claim 11, wherein the buffering pad is made of an elastic body.

14. The camera module of claim 13, wherein the buffering pad is made of a material comprising at least one of rubber, silicon and silicon rubber.
