Abstract

Disclosed is a vehicular camera module having an improved printed circuit board arrangement to downsize the apparatus. A printed circuit board according to one embodiment of the present invention has an image sensor and at least one connector arranged thereon, and can comprise at least one auxiliary substrate connected to the printed circuit board at a predetermined angle by the connector, and an housing attached to the printed circuit board.

Claims

1. A camera module, comprising:

a housing;

a lens module, wherein at least a portion of the lens module is disposed in an inner space of the housing;

a PCB disposed under the lens module;

an image sensor disposed on an upper surface of the PCB; and

a subsidiary substrate electrically connected to the PCB and disposed above the PCB,

wherein the subsidiary substrate is disposed to be inclined with respect to the upper surface of the PCB,

wherein the housing comprises a groove formed on a lower surface of the housing and that is recessed to receive the subsidiary substrate,

wherein the groove of the housing is spaced apart from the inner space of the housing, and

wherein at least a portion of the lens module is overlapped with the subsidiary substrate in a horizontal direction.

2. The camera module of claim 1, wherein the subsidiary substrate is connected to the PCB in a direction vertical to the PCB.

3. The camera module of claim 1, wherein the subsidiary substrate is electrically connected to the PCB via a connector, and

wherein the connector is disposed on a same surface as that on which the image sensor is arranged.

4. The camera module of claim 3, wherein the connector is arranged in a direction in parallel to a distal end of the PCB.

5. The camera module of claim 3, wherein the subsidiary substrate comprises first, second, third, and fourth subsidiary substrates, with the fourth subsidiary substrate being opposite to the third subsidiary substrate based on the image sensor, and

wherein each of the first to fourth subsidiary substrates is configured to be disposed on each side of the rectangular shape of the PCB, respectively.

6. The camera module of claim 1, wherein the subsidiary substrate comprises a first subsidiary substrate and a second subsidiary substrate opposite to the first subsidiary substrate based on the image sensor, and

wherein the PCB is formed with a rectangular shape.

7. The camera module of claim 6, wherein a shape of the groove of the housing corresponds to that of the subsidiary substrate.

8. The camera module of claim 1, wherein the subsidiary substrate comprises a plurality of subsidiary substrates.

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

a cable housing connected to the PCB, and installed with a cable for an external connection.

10. The camera module of claim 5, wherein the subsidiary substrate is electrically connected to the PCB via a connector, and

wherein the connector is disposed on the upper surface of the PCB.

11. The camera module of claim 10, wherein the subsidiary substrate comprises a connecting portion corresponding to the connector.

12. The camera module of claim 11, wherein the connecting portion is formed of a flexible material.

13. The camera module of claim 10, further comprising:

a connection portion electrically connected to the connector and disposed on a lower surface of the subsidiary substrate,

wherein the connector comprises a female connector, and

wherein the connection portion comprises a male connector.

14. The camera module of claim 10, further comprising:

a connection portion electrically connected to the connector and disposed on a lower surface of the subsidiary substrate,

wherein the connector comprises a male connector, and

wherein the connection portion comprises a female connector.

15. The camera module of claim 10, wherein the connector comprises a first connector coupled with the first subsidiary substrate and a second connector coupled with the second subsidiary substrate, and

wherein the image sensor is disposed between the first connector and the second connector.

16. The camera module of claim 15, wherein the connector further comprises a third connector coupled with the third subsidiary substrate and a fourth connector coupled with the fourth subsidiary substrate, and

wherein the image sensor is disposed between the third connector and the fourth connector.

17. The camera module of claim 16, wherein the first subsidiary substrate is in parallel to the third subsidiary substrate.

18. The camera module of claim 17, wherein the first subsidiary substrate is perpendicular to the second subsidiary substrate.

19. A camera module, comprising:

a housing;

a lens module coupled to the housing;

a PCB disposed under the lens module;

an image sensor disposed on an upper surface of the PCB; and

a subsidiary substrate electrically connected to the PCB and disposed above the PCB,

wherein the subsidiary substrate is disposed to be inclined with respect to the upper surface of the PCB,

wherein the housing comprises a groove formed on a lower surface of the housing and that is recessed to receive the subsidiary substrate,

wherein the groove of the housing is spaced apart from the lens module, and

wherein at least a portion of the lens module is overlapped with the subsidiary substrate in a horizontal direction.
