Abstract

An assembly includes a housing arranged to house a sensor. The assembly includes a ring-shaped first shield supported by the housing. The assembly includes a second shield supported by the housing above the first shield and defining an outer perimeter greater than an inner perimeter, and less than an outer perimeter, of the first shield.

First claim

What is claimed is:

1. An assembly, comprising:
a housing arranged to house a sensor;
a ring-shaped first shield supported by the housing, the first shield defining an inner perimeter and an outer perimeter; and
a ring-shaped second shield supported by the housing above the first shield and defining an outer perimeter greater than the inner perimeter of the first shield and less than the outer perimeter of the first shield.

2. The assembly of claim 1 , further comprising a member connecting the first shield to the second shield.

3. The assembly of claim 1 , wherein the outer perimeter of the second shield is vertically spaced above the inner perimeter of the first shield.

4. The assembly of claim 1 , wherein the first shield and the second shield are concentric.

5. The assembly of claim 1 , wherein the sensor is a LIDAR sensor.

6. The assembly of claim 1 , wherein the housing has a bottom configured to mount to a vehicle.

7. The assembly of claim 1 , wherein the first shield slopes downwardly from the inner perimeter to the outer perimeter of the first shield.

8. The assembly of claim 1 , wherein a top of the housing includes a top surface, and the first shield is supported by the top surface.

9. The assembly of claim 1 , wherein the first shield has a top surface that includes a groove elongated radially between the inner perimeter and the outer perimeter of the first shield.

10. The assembly of claim 1 , further comprising a rib on a bottom surface of the first shield elongated radially between the inner perimeter and the outer perimeter.

11. The assembly of claim 1 , wherein the housing is within the inner perimeter of the first shield.

12. The assembly of claim 1 , further comprising a third shield supported by the housing above the second shield and defining an outer perimeter that is greater than the inner perimeter of the second shield and less than the outer perimeter of the second shield.

13. The assembly of claim 1 , further comprising a center shield supported by the housing below the second shield and defining an outer perimeter that is greater than the inner perimeter of the second shield.

14. The assembly of claim 13 , wherein the second shield and the center shield are concentric.

15. The assembly of claim 14 , wherein the center shield is in the inner perimeter of the first shield.

16. The assembly of claim 1 , wherein the first shield is flat.

17. The assembly of claim 1 , wherein a top of the housing has a circumferential surface, and the first shield is supported by the circumferential surface.

18. An assembly, comprising:
means for housing a sensor;
first means for shielding a housing, the first means for shielding the housing defining an inner perimeter and an outer perimeter; and
second means for shielding the housing above the first means for shielding the housing and defining an outer perimeter greater than the inner perimeter of the first means for shielding the housing and less than the outer perimeter of the first means for shielding the housing.

19. The assembly of claim 18 , wherein the first means for shielding the housing includes means for directing water radially from the inner perimeter toward the outer perimeter of the first means for shielding the housing.

20. The assembly of claim 18 , wherein the first means for shielding the housing includes supporting means elongated radially between the inner perimeter and the outer perimeter of the first means for shielding the housing.
