Abstract

Claims (54)

1 . A camera module, comprising:

an optical assembly including a lens having an optical axis;

a first actuator configured to actuate the optical assembly in a first direction that is substantially parallel to the optical axis, the first actuator comprising a first carrier, a guide configured to guide the first carrier, and a shock absorber provided in the first carrier; and

a second actuator configured to actuate the optical assembly in a second direction orthogonal to the first direction that is substantially parallel to the optical axis, the second actuator comprising a second carrier spaced apart from the first carrier, and a stopper provided in the second carrier and configured to restrict a movement of the second carrier,

wherein the shock absorber is provided between the guide and the stopper,

wherein the guide comprises at least one first ball and a guide rail along which the at least one first ball moves, and

wherein the shock absorber comprises a first void portion in the first carrier configured to reduce an impact transmitted from the second carrier to the guide.

2 . The camera module of claim 1 ,

wherein the first carrier comprises a first carrier wall facing a first stopper side surface of the stopper.

3 . The camera module of claim 2 ,

wherein the first void portion is positioned to be spaced apart from the guide.

4 . The camera module of claim 2 ,

wherein the first void portion is configured to at least partially elastically deform.

5 . The camera module of claim 2 ,

wherein the first void portion comprises a recess at least partially formed in the first carrier wall.

6 . The camera module of claim 2 ,

wherein the first carrier further comprises a second carrier wall that intersects with the first carrier wall and faces a second stopper side surface intersecting with the first stopper side surface of the stopper, and

wherein the shock absorber further comprises a second void portion formed in the second carrier wall.

7 . The camera module of claim 6 ,

wherein the second void portion penetrates through the second carrier wall.

8 . The camera module of claim 1 ,

wherein the stopper is spaced apart from the first carrier.

9 . The camera module of claim 1 , further comprising:

a camera housing configured to receive the first carrier and the second carrier, wherein the guide is positioned between the camera housing and the first carrier.

10 . The camera module of claim 1 ,

wherein the guide comprises at least one ball.

11 . The camera module of claim 1 ,

wherein the first carrier comprises a first carrier wall facing a first stopper side surface of the stopper, and

wherein the shock absorber comprises a first flexible flange provided on the first carrier wall and configured to elastically deform relative to the first carrier wall.

12 . The camera module of claim 11 ,

wherein the first flexible flange is provided seamlessly and integrally with the first carrier.

13 . The camera module of claim 11 ,

wherein the first flexible flange is connected to the first carrier so as to be inserted into at least a portion of the first carrier.

14 . The camera module of claim 13 , wherein the first flexible flange is formed of a more elastic material than the first carrier.

15 . The camera module of claim 11 ,

wherein the first carrier further comprises a second carrier wall that intersects with the first carrier wall and faces a second stopper side surface intersecting with the first stopper side surface of the stopper, and

wherein the shock absorber further comprises a second flexible flange provided on the second carrier wall and configured to elastically deform relative to the second carrier wall.

16 . An electronic device, comprising:

a housing; and

a camera module positioned in the housing, wherein the camera module comprises:

an optical assembly including a lens having an optical axis,

a first actuator configured to actuate the optical assembly in a first direction that is substantially parallel to the optical axis, the first actuator comprising a first carrier, a guide configured to guide the first carrier, and a shock absorber provided in the first carrier, and

a second actuator configured to actuate the optical assembly in a second direction orthogonal to the first direction that is substantially parallel to the optical axis, the second actuator comprising a second carrier spaced apart from the first carrier, and a stopper provided in the second carrier and configured to restrict a movement of the second carrier,

wherein the shock absorber is provided between the guide and the stopper,

wherein the guide comprises at least one first ball and a guide rail along which the at least one first ball moves, and

wherein the shock absorber comprises a first void portion in the first carrier configured to reduce an impact transmitted from the second carrier to the guide.

17 . The electronic device of claim 16 ,

wherein the first carrier comprises a first carrier wall facing a first stopper side surface of the stopper.

18 . The electronic device of claim 17 ,

wherein the first void portion is positioned to be spaced apart from the guide.

19 . The electronic device of claim 17 ,

wherein the first void portion is configured to at least partially elastically deform.

20 . The camera module of claim 17 ,

wherein the first void portion comprises a recess at least partially formed in the first carrier wall.
