Abstract

The exemplary embodiment of the present disclosure relates to a camera module including a rear-opened front body, a rear body coupled to a rear side of the front body to form an inner space, a lens part coupled to the front body, an image sensor accommodated at the inner space to convert a light having passed the lens part to an electrical signal, a PCB (Printed Circuit Board) accommodated at the inner space and mounted with the image sensor, and a closed curve-shaped packing member interposed between the front body and the rear body, wherein the packing member includes a support part extensively formed from the packing member to an inner side, and the front body or the rear body includes a support part accommodation groove having a shape corresponding to that of the support part, whereby adhesionability during assembly of packing member can be maximized to thereby minimize an installation defect, a depressed or stamped phenomenon of a packing member that may occur during assembly process.

Claims

1. A camera module, comprising:

a rear-opened front body;

a rear body coupled to a rear side of the front body to form an inner space;

a lens part coupled to the front body;

an image sensor accommodated at the inner space to convert a light having passed the lens part to an electrical signal;

a PCB (Printed Circuit Board) accommodated at the inner space and mounted with the image sensor; and

a closed curve-shaped packing member interposed between the front body and the rear body,

wherein the packing member includes a support part extensively formed from the packing member to an inner side, and the front body or the rear body includes a support part accommodation groove having a shape corresponding to that of the support part.

2. The camera module of claim 1, wherein the packing member includes a first lateral surface and a second lateral surface, and the support part includes a first support part extended from the first lateral surface and a second support part extended from the second lateral surface.

3. The camera module of claim 1, wherein each of the first and second support parts has a different shape.

4. The camera module of claim 2, wherein the first support part is protruded inwardly from the first lateral surface and the first support part is formed with a through hole through which the first support part horizontally passes.

5. The camera module of claim 4, wherein the rear body includes a first support part accommodation groove configured to accommodate the first support part, and a protruder inserted into the through hole by being protrusively formed from the first support part accommodation groove.

6. The camera module of claim 2, wherein the second support part includes a hitching part arranged at an inner side of the second lateral surface and a connection part configured to connect the hitching part and the second lateral surface, wherein width of the connection part is smaller than that of the hitching part.

7. The camera module of claim 6, wherein the rear body includes the hitching part, and a second support part accommodation groove formed in a shape corresponding to that of the hitching part and the connection part to accommodate the hitching part and the connection part.

8. The camera module of claim 6, wherein the rear body includes a partition wall protrusively formed from the rear body to a front side, the packing member is so arranged as to wrap the partition wall in order to allow an inner surface to be contacted by the partition wall, and the partition wall includes a distancing part having a width corresponding to that of the connection part to accommodate the connection part.

9. The camera module of claim 8, wherein at least a part of the hitching part is so arranged as to contact the inner surface of the partition wall.

10. The camera module of claim 1, wherein the packing member is formed with a silicone or a rubber.

11. The camera module of claim 2, wherein the first lateral surface and the second lateral surface are so arranged as to be adjacently positioned.

12. The camera module of claim 2, wherein the first lateral surface and the second lateral surface are so arranged as to face each other.

13. The camera module of claim 2, wherein the second lateral surface is positioned adjacent to the first lateral surface, the packing member includes a third lateral surface adjacent to the second lateral surface and a fourth lateral surface adjacent to the first lateral surface, and the support part further includes a third support part extended from the third lateral surface and a fourth support part extended from the fourth lateral surface.

14. The camera module of claim 13, wherein one of the first to fourth support parts has a shape different from that of the other three support parts.

15. The camera module of claim 1, wherein the lens part includes at least one lens, and a barrel configured to support the lens, and a sealing member is interposed between the barrel and the front body.

16. The camera module of claim 1, wherein the front body and the rear body are coupled by a screw.

17. The camera module of claim 16, wherein the packing member further includes an avoidance part so formed as to prevent interference with the screw.

18. A camera for a vehicle, comprising:

a rear-opened front body;

a rear body coupled to a rear side of the front body to form an inner space;

a lens part coupled to the front body;

an image sensor accommodated at the inner space to convert a light having passed the lens part to an electrical signal;

a PCB (Printed Circuit Board) accommodated at the inner space and mounted with the image sensor; and

a closed curve-shaped packing member interposed between the front body and the rear body,

wherein the packing member includes a support part extensively formed from the packing member to an inner side, and the front body or the rear body includes a support part accommodation groove having a shape corresponding to that of the support part.
