Abstract

A camera module for a motor vehicle having a camera unit with a camera and a lens, wherein the camera unit is arranged in a housing, and wherein the camera unit is designed to be movable between a passive position, in which the camera unit is arranged at least partially in the housing, and an active position, in which the camera unit serves to visually detect an outer area of a motor vehicle, and with a drive unit which is coupled to the camera unit and is designed to move the camera unit between the passive position and the active position, and with a cleaning device for cleaning the lens of the camera unit with a jet of fluid, wherein the camera module has a deflection element for deflecting the jet of fluid onto the lens.

Claims

1. A camera module for a motor vehicle, the camera unit comprising:

a camera unit including a camera and a lens, the camera unit being arranged in a housing and operable to be moved between a passive position in which the camera unit is at least partially located in the housing and an active position in which the camera unit is used for image acquisition of an outside area of the motor vehicle;

a drive unit coupled to the camera unit and operable to move the camera unit between the passive position and the active position;

a cleaning device for cleaning the lens of the camera unit with a fluid jet; and

a deflection element operable to deflect the fluid jet onto the lens.

2. The camera module according to claim 1, wherein the deflection element is operable to deflect the fluid jet for cleaning an entire outer lens surface of the lens.

3. The camera module according to claim 1, wherein the camera module includes a door operable to cover the camera unit in the passive position.

4. The camera module according to claim 3, wherein the deflection element is located on the door.

5. The camera module according to claim 3, wherein the deflection element is formed as a single piece with the door.

6. The camera module according to claim 3, wherein the deflection element is clipped onto the door.

7. The camera module according to claim 3, wherein the deflection element is located at the center of the door adjacent to the lens of the camera unit.

8. The camera module according to claim 1, wherein the deflection element includes the shape of a ramp.

9. The camera module according to claim 1, wherein the deflection element is concave.

10. The camera module according to claim 1, wherein the deflection element is pivotable.

11. The camera module according to claim 1, wherein the cleaning device is rod-shaped.

12. The camera module according to claim 1, wherein the cleaning device is coupled to the drive unit.

13. The camera module according to claim 1, wherein the cleaning device is located in a fixed position on the housing.

14. The camera module according to claim 1, wherein the camera module includes a door operable to cover the camera unit in the passive position, the door being pivotable relative to the housing.

15. The camera module according to claim 14, wherein the door is coupled to the drive unit.

16. The camera module according to claim 14, wherein the door is operable to be opened by the motion of the camera from the passive position to the active position.

17. The camera module according to claim 16, wherein the door is spring-mounted.
