Abstract

Claims (48)

1. A camera module comprising:

a housing comprising a body and an accommodation unit extending in an optical axis direction from a central region of the body;

an outermost lens disposed on an upper part of the accommodation unit;

a substrate coupled to a lower part of the housing;

a connector coupled to a lower surface of the substrate;

a heating member disposed on one side of the outermost lens; and

a transmission member connecting the heating member and the connector,

wherein the substrate comprises a first groove formed on a side surface thereof and being penetrated by the transmission member,

wherein the housing comprises a partition wall extending from a lower surface thereof and coupled to an upper surface of the substrate, and

wherein the first groove is located outside the partition wall and the partition wall is in contact with a region adjacent to the first groove among edge regions of the upper surface of the substrate.

2. The camera module according to claim 1 , wherein the partition wall is overlapped with one of the edge regions of the upper surface of the substrate in the optical axis direction.

3. The camera module according to claim 2 , wherein the one of the edge regions of the upper surface of the substrate is in contact with a lower surface of the partition wall, and

wherein the upper surface of the substrate is sealed from the outside by the partition wall.

4. The camera module according to claim 1 , wherein the partition wall comprises a hole being penetrated through by the transmission member.

5. The camera module according to claim 4 , wherein the transmission member comprises a first region connected to the heating member, a second region connected to the connector, and a third region connecting the first region and the second region.

6. The camera module according to claim 5 , wherein at least a portion of the third region is bent.

7. A camera module comprising:

a housing comprising a body and an accommodation unit extending from a central region of the body in an optical axis direction;

an outermost lens disposed on an upper part of the accommodation unit;

a substrate coupled to a lower part of the housing;

a heating member disposed on one side of the outermost lens; and

a transmission member connecting the heating member and the substrate;

wherein the accommodation unit comprises a hole extending in an optical axis direction,

wherein the substrate comprises a first groove formed concave inwardly from a side surface,

wherein the transmission member passes through the hole and the first groove,

wherein the housing comprises a partition wall extending downward from a lower surface thereof and coupled to an upper surface of the substrate, and

wherein the first groove is located outside the partition wall and the partition wall is in contact with a region adjacent to the first groove among edge regions of the upper surface of the substrate.

8. The camera module according to claim 4 , comprising at least one lens disposed in the accommodation unit and disposed on one side of the outermost lens,

wherein the hole is spaced apart from the at least one lens in a direction perpendicular to the optical axis, and

wherein the at least one lens is screw-coupled to an inner circumferential surface of the accommodation unit.

9. The camera module according to claim 8 , wherein the accommodation unit comprises a second groove formed on a lower surface, and

wherein the second groove is overlapped with the at least one lens in a direction perpendicular to the optical axis.

10. The camera module according to claim 1 , comprising a retainer coupled to an upper portion of the accommodation unit to fix the outermost lens.

11. The camera module according to claim 10 , comprising an O-ring disposed between the outermost lens and the retainer.

12. The camera module according to claim 7 , wherein the partition wall is overlapped with one of the edge regions of the upper surface of the substrate in the optical axis direction.

13. The camera module according to claim 12 , wherein the one of the edge regions of the upper surface of the substrate is in contact with a lower surface of the partition wall, and

wherein the upper surface of the substrate is sealed from the outside by the partition wall.

14. The camera module according to claim 7 , comprising at least one lens disposed on the accommodation unit and disposed on one side of the outermost lens,

wherein the hole is spaced apart in a direction perpendicular to the optical axis, and

wherein the at least one lens is screw-coupled to an inner circumferential surface of the accommodation unit.

15. The camera module according to claim 14 , wherein the accommodation unit comprises a second groove formed on a lower surface, and

wherein the second groove is overlapped with the at least one lens in a direction perpendicular to the optical axis.

16. The camera module according to claim 7 , comprising a connector disposed on a lower surface of the substrate.

17. The camera module according to claim 16 , wherein the transmission member comprises a first region connected to the heating member, a second region connected to the connector, and a third region connecting the first region and the second region.

18. The camera module according to claim 17 , wherein at least a portion of the third region of the transmission member is bent.

19. The camera module according to claim 7 , comprising:

a retainer coupled to an upper part of the accommodation unit to fix the outermost lens; and

an O-ring disposed between the outermost lens and the retainer.
