Vehicle sensor assembly
An assembly includes a housing defining a chamber and having an air inlet. The assembly includes a blower in the chamber and in fluid communication with the air inlet. The assembly includes a sensor defining a field of view and supported by the housing. The housing has an outlet vent of variable size. The outlet vent is in communication with the blower and aimed across the field of view of the sensor.
1. An assembly, comprising:
a housing defining a chamber and having an air inlet;
a blower in the chamber and in fluid communication with the air inlet; and
a sensor having a field of view and supported by the housing;
the housing having a first outlet vent of variable size, the first outlet vent in communication with the blower and aimed across the field of view of the sensor, the first outlet vent forward of and spaced from the sensor along a first axis, the first outlet vent having a variable width along the first axis, and the first outlet vent having a fixed length along a second axis that is perpendicular to the first axis, and wherein the width of the first outlet vent can be varied along the first axis while the length of the first outlet vent along the second axis remains fixed.
2. The assembly of claim 1 , wherein the first outlet vent includes a plate movable between a first position and a second position, the first outlet vent having a larger size when the plate is in the first position than in the second position.
3. The assembly of claim 1 , wherein the first outlet vent is pivotable relative to the housing.
4. The assembly of claim 1 , wherein the housing has a second outlet vent aimed to direct air across the field the field of view of the sensor between the sensor and air elected from the first outlet vent.
5. The assembly of claim 4 , wherein the first outlet vent partially encircles the sensor and the second outlet vent encircles the field of view of the sensor.
6. The assembly of claim 1 , wherein the housing has a second outlet vent between the sensor and the first outlet vent.
7. The assembly of claim 1 , further comprising a lens in the field of view of the sensor, the housing having a second outlet vent aimed to direct air across the lens.
8. The assembly of claim 1 , wherein the first outlet vent is arcuate.
9. The assembly of claim 1 , wherein the sensor is a LIDAR sensor and extends from the housing.
10. A vehicle, comprising:
a roof;
a housing supported by the roof, the housing defining a chamber and having an air inlet;
a blower in the chamber and in fluid communication with the air inlet;
a sensor supported by the housing and having a field of view; and
the housing having a first outlet vent with a fixed length along a cross-vehicle axis of the vehicle and a variable width along a vehicle-longitudinal axis of the vehicle, the outlet vent in communication with the blower and aimed across the field of view of the sensor, and wherein the width of the first outlet vent can be varied along the vehicle-longitudinal axis while the length of the first outlet vent along the cross-vehicle axis remains fixed.
11. The vehicle of claim 10 , wherein the first outlet vent is forward of the sensor along the vehicle-longitudinal axis of the vehicle.
12. The vehicle of claim 10 , further comprising a lens in the field of view of the sensor, the housing having a second outlet vent aimed to direct air across the lens.
13. The vehicle of claim 10 , wherein the first outlet vent is aimed to direct air upward.
14. The vehicle of claim 10 , wherein the sensor is a LIDAR sensor and extends upward from the housing.
15. The vehicle of claim 10 , wherein the first outlet vent includes a plate movable between a first position and a second position, the outlet vent having a larger size when the plate is in the first position than in the second position.
16. The vehicle of claim 15 , wherein the plate is movable along the vehicle-longitudinal axis.
17. The vehicle of claim 10 , wherein the first outlet vent is pivotable about the cross-vehicle axis.
18. The vehicle of claim 10 , wherein the housing has a second outlet vent aimed to direct air across the field of view of the sensor between the sensor and air elected from the first outlet vent, and wherein the first outlet vent partially encircles the sensor and the second outlet vent encircles the field of view of the sensor.
19. An assembly, comprising:
a housing defining a chamber and having an air inlet;
a blower in the chamber and in fluid communication with the air inlet; and
a sensor having a field of view and supported by the housing;
the housing having a first outlet vent of variable size;
the housing having a second outlet vent aimed to direct air across the field of view of the sensor between the sensor and air elected from the first outlet vent;
the first outlet vent is in communication with the blower and aimed across the field of view of the sensor; and
the first outlet vent partially encircles the sensor and the second outlet vent encircles the field of view of the sensor.
