Abstract

A camera module includes a housing having an internal space, a carrier accommodated in the housing and configured to move in an optical axis direction, a first frame accommodated in the carrier and configured to move in a first axis direction, perpendicular to an optical axis and in a second axis direction, perpendicular to both the optical axis and a first axis, a stopper coupled to the carrier to cover the first frame, a case coupled to the housing to cover the internal space, and a damper member provided on the housing and the stopper, and including a first damper member, a second damper member, and a third damper member, which face a counterpart member in different directions, and at least one of the first damper member, the second damper member, and the third damper member is provided in the housing, and remainders thereof are provided in the stopper.

First claim

What is claimed is:

1 . A camera module, comprising:
a housing having an internal space; a carrier, accommodated in the housing, and configured to move in an optical axis direction, with respect to the housing; a first frame, accommodated in the carrier, and configured to move in a first axis direction, perpendicular to an optical axis and in a second axis direction, perpendicular to both the optical axis and a first axis, with respect to the carrier; a stopper coupled to the carrier to cover the first frame; a case coupled to the housing to cover the internal space; and a damper member provided on the housing and the stopper, wherein the damper member comprises a first damper member, a second damper member, and a third damper member, which each face a respective counterpart member in different directions, and at least one of the first damper member, the second damper member, and the third damper member is provided on the housing, and remaining damper members of the first damper member, the second damper member, and the third damper member are provided on the stopper.

2 . The camera module of claim 1 , wherein the first damper member faces a first counterpart member in the optical axis direction, the second damper member faces a second counterpart member in the first axis direction, and the third damper member faces a third counterpart member in the second axis direction.

3 . The camera module of claim 2 , wherein the first damper member and the second damper member are provided on the stopper, and the third damper member is provided on the housing.

4 . The camera module of claim 3 , wherein:
the stopper comprises: a body disposed to cover the first frame; and a fastening portion, coupled to the carrier, and extending from the body in the optical axis direction, wherein the first damper member is disposed on the body, and penetrates through the body in the optical axis direction, and the second damper member is disposed on the body, and penetrates through the fastening portion in the first axis direction.

5 . The camera module of claim 4 , wherein a first side of the first damper member faces the case and a second side of the first damper faces the first frame.

6 . The camera module of claim 4 , wherein a first side of the second damper member faces the housing and a second side of the second damper faces the first frame.

7 . The camera module of claim 3 , wherein:
the third damper member is formed to protrude from one side of the housing toward the internal space in the second axis direction, and the third damper member faces the carrier.

8 . The camera module of claim 1 , wherein the first damper member, the second damper member, and the third damper member are each provided as a separate member.

9 . The camera module of claim 1 , wherein the first damper member, the second damper member, and the third damper member are formed of an elastic material.

10 . The camera module of claim 1 , further comprising:
a lens barrel, coupled to the first frame, and comprising at least one lens, wherein the lens barrel is configured to move in the first axis direction and the second axis direction together with the first frame, and wherein the lens barrel and the first frame are configured to move in the optical axis direction together with the carrier.

11 . A camera module comprising:
a housing unit having an internal space; a carrier accommodated in the housing unit; a first frame, accommodated in the carrier, and coupled to a lens barrel; a stopper coupled to the carrier in an optical axis direction; and a damper member provided on the housing unit and the stopper, wherein the damper member comprises:
a first damper member and a second damper member disposed on the stopper and configured to face the housing unit and the first frame; and
a third damper member disposed on the housing unit and configured to face the carrier.

12 . The camera module of claim 11 , wherein:
the first damper member faces the housing unit and the first frame in the optical axis direction, and the first damper comprises: a first protrusion that protrudes from the stopper toward the housing unit in the optical axis direction and a second protrusion that protrudes from the stopper toward the first frame in the optical axis direction.

13 . The camera module of claim 11 , wherein:
the second damper member faces the housing unit and the first frame in a first axis direction, perpendicular to an optical axis, and the second damper comprises: a third protrusion that protrudes from the stopper toward the housing unit in the first axis direction and a fourth protrusion that protrudes from the stopper toward the first frame in the first axis direction.

14 . The camera module of claim 11 , wherein the third damper member faces the carrier in a second axis direction, perpendicular to an optical axis, and protrudes from one side of the housing unit toward the carrier in the second axis direction.

15 . The camera module of claim 11 , wherein the first damper member, the second damper member, and the third damper member are each provided as a separate member.

16 . The camera module of claim 11 , wherein:
the stopper comprises: a body disposed to cover the first frame; and a plurality of fastening portions coupled to the carrier, and extending from each corner of the body in the optical axis direction, wherein the first damper member is disposed on the body, and the second damper member is disposed on at least a portion of the plurality of fastening portions.
