Abstract

A camera module for a vehicle according to the present invention includes a first Printed Circuit Board (PCB) configured to have an image sensor mounted on its surface; a second PCB configured to supply a power source to the first PCB; an outer shield installed to surround the side of the first and the second PCBs and to shield the first and the second PCBs from electromagnetic interference (EMI); and a plurality of support units disposed at positions where the supports units interfere with the first and the second PCBs of the outer shield and configured to support the first and the second PCBs.

Claims

1. A camera module, comprising:

a first PCB (printed circuit board);

a second PCB configured to supply power to the first PCB; and

an outer shield having a first hole and a second hole and distancing the first PCB from the second PCB at a predetermined distance,

wherein the outer shield includes four lateral surfaces and is formed in one body with a conductive material,

wherein the first PCB includes a first support protrusion protrusively formed at a first lateral surface thereof,

wherein the second PCB includes a second support protrusion protrusively formed at a second lateral surface thereof,

wherein the first support protrusion is disposed in the first hole, and

wherein the second support protrusion is disposed in the second hole.

2. The camera module of claim 1, wherein the outer shield supports the first and second PCBs.

3. The camera module of claim 1, wherein the first hole and the second hole are spaced apart from each other such that the first PCB is distanced from the second PCB at the predetermined distance.

4. The camera module of claim 1, wherein the first support protrusion includes a first ground portion of conductive material, and

wherein the second support protrusion includes a second ground portion of conductive material.

5. The camera module of claim 1, wherein the holes are vertically arranged in a pair at a lateral surface of the outer shield.

6. The camera module of claim 1, wherein the outer shield is integrally formed with a conductive material.

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

a lens module disposed on the first PCB; and

a cover member covering the lens module and the first PCB.

8. The camera module of claim 1, wherein the outer shield supports at least three surfaces of the first PCB and at least three surfaces of the second PCB.

9. The camera module of claim 1, wherein the first PCB further includes a first concave groove next to the first support protrusion, and wherein the second PCB further includes a second concave groove next to the second support protrusion.

10. The camera module of claim 4, wherein the first and second PCBs are electrically connected via the outer shield.

18. A vehicle comprising the camera module of claim 1.

11. A camera module, comprising:

a first PCB (Printed Circuit Board);

a second PCB configured to supply power to the first PCB;

an outer shield configured to distance the first PCB from the second PCB at a predetermined distance;

a first support protrusion protrusively formed at a first lateral surface of the first PCB and disposed in a first hole formed on the outer shield; and

a second support protrusion protrusively formed at a second lateral surface of the second PCB and disposed in a second hole formed on the outer shield.

12. The camera module of claim 11, wherein the outer shield supports the first and second PCBs.

13. The camera module of claim 11, wherein the first hole and the second hole are spaced apart from each other such that the first PCB is distanced from the second PCB at the predetermined distance.

14. The camera module of claim 11, wherein the first support protrusion includes a first ground portion of conductive material, and

wherein the second support protrusion includes a second ground portion of conductive material.

15. The camera module of claim 14, wherein the first and second PCBs are electrically connected via the outer shield.

16. The camera module of claim 11, wherein the holes are vertically arranged in a pair at a lateral surface of the outer shield.

17. The camera module of claim 11, further comprising:

a lens module arranged on the first PCB; and

a cover member covering the lens module and the first PCB.
