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.

First claim

What is claimed is:

1. A camera module, comprising:
a first PCB (printed circuit board);
a second PCB spaced apart from the first PCB; and
an outer shield supporting the first and second PCBs and configured to distance the first PCB from the second PCB;
wherein the outer shield includes a first lateral wall, a second lateral wall opposite to the first lateral wall, a first hole formed on the first lateral wall, a second hole formed on the second lateral wall, a third hole formed on the first lateral wall and spaced apart from the first hole, and a fourth hole formed on the second lateral wall and spaced apart from the second hole;
wherein the first PCB includes a first support protrusion disposed at a portion of a first lateral surface of the first PCB and a second support protrusion disposed at a portion of a second lateral surface of the first PCB opposite to the first lateral surface of the first PCB,
wherein the second PCB includes a third support protrusion disposed at a portion of a third lateral surface of the second PCB and a fourth support protrusion disposed at a portion of a fourth lateral surface of the second PCB opposite to the third lateral surface of the second PCB, and
wherein the first support protrusion is disposed in the first hole,
the second support protrusion is disposed in the second hole, the third support protrusion is disposed in the third hole, and the fourth support protrusion is disposed in the fourth hole.

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

3. 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.

4. The camera module of claim 1 , wherein the first hole and the third hole are vertically arranged in a pair at the first lateral wall of the outer shield.

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

6. 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.

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

8. The camera module of claim 1 , wherein the first PCB further includes first and second concave grooves next to the first support protrusion, and wherein the second PCB further includes third and fourth concave grooves next to the third support protrusion.

9. The camera module of claim 3 , wherein the first ground portion and the second ground portion contact with the outer shield, and
wherein the first and second PCBs are electrically connected via the outer shield.

10. The camera module of claim 1 , wherein the outer shield further includes a third lateral wall disposed between the first lateral wall and the second lateral wall, and a fifth hole formed on the third lateral wall;
wherein the first PCB further includes a fifth support protrusion formed on the first PCB and disposed in the fifth hole.

11. A camera module, comprising:
a first PCB (Printed Circuit Board);
a second PCB configured to supply power to the first PCB and spaced apart from the first PCB; and
an outer shield having a first hole and a second hole, distancing the first PCB from the second PCB at a predetermined distance, and formed in one body with conductive material;
wherein the first PCB includes a first support protrusion disposed at a first lateral surface thereof,
wherein the second PCB includes a second support protrusion disposed 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,
wherein first support protrusion includes a first ground portion at an upper surface of the first protrusion or a bottom surface of the first support protrusion, and
wherein second support protrusion includes a second ground portion at an upper surface of the second protrusion or a bottom surface of the second support protrusion.

12. The camera module of claim 11 , wherein the outer shield further comprises a third hole and a fourth hole,
wherein the first hole and the third hole are spaced apart from each other such that the first PCB is distanced from the second PCB at the predetermined distance, and
wherein the second hole and the fourth hole are spaced apart from each other such that the first PCB is distanced from the second PCB at the predetermined distance.

13. 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.

14. The camera module of claim 13 , wherein the first and second PCBs are electrically connected via the outer shield.

15. The camera module of claim 11 , wherein the outer shield includes four lateral walls,
wherein the first hole and the third hole are vertically arranged in a pair at a first lateral wall of the outer shield, and
wherein the second hole and the fourth hole are vertically arranged in a pair at a second lateral wall of the outer shield.

16. 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.

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

18. The camera module of claim 15 , wherein the outer shield further includes a third lateral wall disposed between the first lateral wall and the second lateral wall, and a fifth hole formed on the third lateral wall;
wherein the first PCB further includes a fifth support protrusion formed on the first PCB and disposed in the fifth hole.
