Abstract

Claims (26)

1. A sensor assembly comprising:

a housing including an outlet;

a sensor window, the sensor window fixed relative to the housing, the outlet aimed to direct air across the sensor window;

a flap rotatably coupled to the housing at the outlet; and

a deflector covering the flap, the flap disposed between the outlet and the deflector and rotatable from a first position extending across the outlet toward the deflector to a second position;

the deflector and the flap defining an air flow passage between the deflector and the flap; and

the housing and the flap defining a second air flow passage, the flap being between the air flow passage and the second air flow passage.

2. The sensor assembly of claim 1 , further comprising a member fixed to the housing and positioned to limit movement of the flap toward the deflector.

3. The sensor assembly of claim 1 , further comprising a plurality of flaps including the flap, the flaps each being rotatable toward and away from the deflector.

4. The sensor assembly of claim 3 , wherein the outlet is elongated parallel to the sensor window alongside the sensor window in a direction of elongation, and the flaps are arranged in series along the direction of elongation of the outlet.

5. The sensor assembly of claim 4 , wherein the flaps are spaced from each other along the direction of elongation.

6. The sensor assembly of claim 3 , wherein the flaps are rotatable independently of each other.

7. The sensor assembly of claim 1 , wherein the flap includes vanes extending from an external surface toward the deflector.

8. The sensor assembly of claim 7 , wherein the outlet is elongated parallel to the sensor window alongside the sensor window in a direction of elongation, and the vanes are elongated perpendicular to the direction of elongation of the outlet.

9. The sensor assembly of claim 7 , wherein the flap includes second vanes extending from an internal surface away from the deflector.

10. The sensor assembly of claim 7 , wherein the vanes are triangular in cross section.

11. The sensor assembly of claim 1 , wherein the air flow passage extends from a first end of the deflector to a second end of the deflector.

12. The sensor assembly of claim 11 , wherein the flap is between the first end and the second end of the deflector.

13. The sensor assembly of claim 11 , wherein the outlet of the housing is between the first end and the second end of the deflector.

14. The sensor assembly of claim 11 , wherein the deflector extends from the first end toward the sensor window to the second end.

15. The sensor assembly of claim 11 , further comprising a base, the housing rotatably coupled to the base to rotate about an axis, the second end of the deflector radially inward of the first end of the deflector relative to the axis.

16. The sensor assembly of claim 15 , wherein the first end of the deflector is spaced from the housing and is forward of the second end in a direction of rotation of the housing relative to the base.

17. The sensor assembly of claim 15 , wherein the first end of the deflector is spaced from the housing to direct air into the airflow passage when the housing rotates relative to the base.

18. The sensor assembly of claim 1 , wherein the housing includes a cylindrical panel, and the sensor window is recessed from the cylindrical panel.

19. The sensor assembly of claim 18 , wherein the housing includes a recess panel extending radially inward from the cylindrical panel toward the sensor window, and the recess panel includes the outlet.

20. The sensor assembly of claim 18 , wherein the outlet and the flap are elongated parallel to an axis defined by the cylindrical panel.
