Abstract

A vehicle camera protection and cleaning system is disclosed in which at least one wiper is positioned on an underside surface of a camera cover to clean a lens of a vehicle camera. In one embodiment, the system includes an inner ring fixedly attached to an underside surface of the cover, and a plurality of aperture members pivotally connected to the inner ring on one end and pivotally connected on another end to an outer gear that is movable relative to the inner gear, where at least one of the plurality of aperture members comprises a wiper configured to clean a lens of the camera when the aperture members are moved over the lens. In other embodiments, the wiper may be positioned on an underside surface of a cover of the camera that either rotates in a circular manner or translates over the lens of the camera.

First claim

What is claimed is:

1. A vehicle camera protection and cleaning system comprising a camera cover, the camera cover comprising:
an inner ring fixedly attached to an underside surface of the cover; and
a plurality of aperture members pivotally connected to the inner ring on one end and pivotally connected on another end to an outer ring that is movable relative to the inner ring, wherein at least one of the plurality of aperture members comprises a wiper configured to clean a lens of a camera when the aperture members are moved over the lens.

2. The system of claim 1 , wherein the wiper comprises a brush.

3. The system of claim 1 , wherein the wiper comprises a plastic or a rubber.

4. The system of claim 1 , wherein the wiper comprises a plurality of wiping elements configured to sweep across the lens of the camera.

5. The system of claim 1 , comprising a controller including a processor and memory configured to control movement of the aperture members to clean the camera lens.

6. The system of claim 5 , wherein the controller controls the movement of the aperture members over a predetermined period of time.

7. The system of claim 5 , wherein the controller controls the movement of the aperture members in a predetermined cycle.

8. The system of claim 1 , wherein the aperture members are positioned side by side along a circumference of the inner ring.

9. The system of claim 1 , comprising a motor configured to rotate the outer ring.

10. A vehicle camera protection and cleaning system comprising a camera cover, the system comprising:
a motor connected to the cover, the motor configured to rotate the cover in a circular manner;
an aperture defined by a plurality of walls in the cover, the aperture configured to provide an opening for a camera for viewing a vicinity around a vehicle; and
a plurality of wipers positioned on an underside surface of the cover, the wipers configured to clean a lens of the camera when the cover is moved over the lens.

11. The system of claim 10 , wherein the wiper comprises a brush.

12. The system of claim 10 , wherein the wiper comprises a plastic or a rubber.

13. The system of claim 10 , wherein the wiper comprises a plurality of wiping elements configured to sweep across the lens of the camera.

14. The system of claim 10 , comprising a controller including a processor and memory configured to control movement of the cover over the camera lens.

15. The system of claim 14 , wherein the controller controls the movement of the cover over a predetermined period of time.

16. The system of claim 14 , wherein the controller controls the movement of the cover in a predetermined cycle.

17. A vehicle camera protection and cleaning system comprising a camera cover, the system comprising:
a motor connected to the cover, the motor configured to translate the cover over a camera lens;
at least one wiper positioned on an underside surface of the cover, the at least one wiper configured to clean the lens of a camera when the cover is translated over the lens; and
a controller including a processor and memory connected to the motor, the controller configured to control the movement of the cover over the camera lens.

18. The system of claim 17 , wherein the wiper comprises a brush.

19. The system of claim 17 , wherein the wiper comprises a plastic or a rubber.

20. The system of claim 17 , wherein the wiper comprises a plurality of wiping elements configured to sweep across the lens of the camera.
