Abstract

Disclosed herein is a camera module for vehicles. The camera module includes an upper housing accommodating at least one lens which brings an image of a subject into focus. A circuit board has an image sensor mounted thereon. The image sensor converts the image received through the lens into an electric signal. A lower housing is fastened to the upper housing, thus sealing an internal space receiving the image sensor and the circuit board. The camera module reduces the number of fastened parts, thus improving waterproof performance and assemblability.

Claims

1. A camera module for vehicles, comprising:

an upper housing accommodating at least one lens which brings an image of a subject into focus;

a circuit board on which an image sensor is mounted, the image sensor converting the image received through the lens into an electric signal; and

a lower housing fastened to the upper housing, thus sealing an internal space receiving the image sensor and the circuit board.

2. The camera module as set forth in claim 1, wherein the upper housing is integrated with a barrel part which has an inner opening for accommodating the lens.

3. The camera module as set forth in claim 1, wherein the upper housing and the lower housing have a cylindrical structure, and are fastened to each other in a threaded manner.

4. The camera module as set forth in claim 3, wherein parts of the upper housing and the lower housing which are fastened to each other in a threaded manner are adhered using adhesive means.

5. The camera module as set forth in claim 3, wherein an external threaded part is formed on an outer circumference of the upper housing, and an internal threaded part is formed on an inner circumference of the lower housing to engage with the external threaded part.

6. The camera module as set forth in claim 3, wherein an external threaded part is formed on an outer circumference of the lower housing, and an internal threaded part is formed on an inner circumference of the upper housing to engage with the external threaded part.

7. The camera module as set forth in claim 1, wherein the circuit board is fastened to the lower housing.

8. The camera module as set forth in claim 7, wherein the lower housing is provided with an inner step for supporting the circuit board, and the circuit board is coupled to the inner step using a screw.

9. The camera module as set forth in claim 1, wherein the upper housing has an IR filter therein.

10. The camera module as set forth in claim 1, wherein a connector for forming a connection with an external device is fastened to the lower housing.
