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 spaced apart from the first PCB;

a lens module disposed over the first PCB; and

an outer shield supporting the first PCB and the second PCB;

wherein the first PCB has a first PCB protrusion supported by the outer shield,

wherein the second PCB has a second PCB protrusion supported by the outer shield,

wherein the outer shield comprises a sidewall, a first hole formed through the sidewall, a second hole formed through the sidewall directly below the first hole, a first tension spring bent from the sidewall and extending into the first hole, and a second tension spring bent from the sidewall and extending into the second hole,

wherein the first tension spring and the second tension spring are monolithically formed with the sidewall,

wherein at least a portion of the first PCB protrusion is disposed in the first hole, and

wherein at least a portion of the second PCB protrusion is disposed in the second hole.

2. The camera module of claim 1,

wherein the first PCB has a plurality of the first PCB protrusions formed along a circumference of the first PCB, and

wherein the second PCB has a plurality of the second PCB protrusions formed along a circumference of the second PCB.

3. The camera module of claim 1, wherein the first PCB protrusion or the second PCB protrusion includes a ground terminal unit plated with conductive material and formed at a position where the first PCB protrusion or the second PCB protrusion is disposed in the first hole or the second hole.

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

5. The camera module of claim 1, comprising:

a cover member configured to cover a top of the lens module and the first PCB.

6. The camera module of claim 1, wherein the first PCB comprises a plurality of ground portions formed along a circumference of the first PCB, and wherein the second PCB comprises a plurality of ground portions formed along a circumference of the second PCB.

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

8. The camera module of claim 1, wherein the first PCB protrusion comprises a first ground terminal in direct physical contact with the first tension spring.

9. The camera module of claim 8, wherein the second PCB protrusion comprises a second ground terminal in direct physical contact with the second tension spring.

10. The camera module of claim 1, wherein the first tension spring has a curved shape and supports the first PCB protrusion, and

wherein the second tension spring has a curved shape and supports the second PCB protrusion.
