Abstract

A sensor assembly includes a housing having an airfoil shape and including a pressure surface and a suction surface, a sensor attached to the housing and disposed on the suction surface, and a nozzle attached to the housing and directed toward the sensor. A vehicle may include an exterior panel, and the sensor assembly may be attached to the exterior panel.

First claim

What is claimed is:

1. A sensor assembly comprising:
a housing having an airfoil shape, wherein an airfoil shape is defined as having an exterior pressure surface and an exterior suction surface and when moving in a direction of travel producing a force perpendicular to the direction of travel resulting from comparatively lower pressure experienced by the exterior suction surface than experienced by the exterior pressure surface, wherein the housing includes an attachment end, and both surfaces are elongated together away from the attachment end;
a sensor attached to the housing, disposed on the exterior suction surface, and spaced from the exterior pressure surface; and
a nozzle attached to the housing and directed toward the sensor.

2. The sensor assembly of claim 1 , wherein the housing is attachable to a vehicle at the attachment end.

3. The sensor assembly of claim 2 , wherein the exterior suction surface faces down when the housing is attached to the vehicle.

4. The sensor assembly of claim 1 , further comprising a lamp attached to the housing.

5. The sensor assembly of claim 4 , wherein the lamp is disposed on the exterior suction surface of the housing.

6. The sensor assembly of claim 5 , wherein the lamp is a puddle lamp.

7. The sensor assembly of claim 1 , wherein the lamp is closer to the attachment end than the sensor.

8. The sensor assembly of claim 7 , wherein the attachment end is attachable to a vehicle, and the lamp is farther down than the sensor when the attachment end is attached to the vehicle.

9. The sensor assembly of claim 8 , wherein the lamp is directed straighter downward than the sensor when the attachment end is attached to the vehicle.

10. The sensor assembly of claim 1 , wherein the sensor includes a lens, and the nozzle is positioned to spray liquid over an entirety of the lens.

11. The sensor assembly of claim 10 , wherein the nozzle is farther from the attachment end than the sensor.

12. The sensor assembly of claim 1 , wherein the sensor is a camera.

13. The sensor assembly of claim 12 , wherein the camera includes a fisheye lens.

14. The sensor assembly of claim 1 , wherein the exterior suction surface includes a protruding portion on which the sensor is disposed.

15. A vehicle comprising:
an exterior panel;
a housing elongated from the exterior panel, the housing having an airfoil shape, wherein an airfoil shape is defined as having an exterior pressure surface and an exterior suction surface and when moving in a direction of travel producing a force perpendicular to the direction of travel resulting from comparatively lower pressure experienced by the exterior suction surface than experienced by the exterior pressure surface, both surfaces elongated together away from the exterior panel;
a sensor attached to the housing and disposed on the exterior suction surface and spaced from the exterior pressure surface; and
a nozzle attached to the housing and directed toward the sensor.

16. The vehicle of claim 15 , further comprising a door including the exterior panel.

17. The vehicle of claim 15 , wherein the exterior suction surface faces down, and the pressure surface faces up.

18. The vehicle of claim 17 , wherein the nozzle is farther from the exterior panel than the sensor.

19. The vehicle of claim 15 , wherein the exterior pressure surface and the exterior suction surface border each other along a leading edge defined by the airfoil shape and along a trailing edge defined by the airfoil shape.

20. The vehicle of claim 19 , wherein a length from any point of the leading edge, in a direction opposite a direction of travel of the vehicle to the trailing edge, is longer for the exterior suction surface than for the exterior pressure surface.
