Sensor assembly
A sensor assembly includes a housing defining a chamber and a sensor positioned in the chamber. The housing includes a wall. The wall includes a recessed portion. The recessed portion includes a port. The sensor has a field of view extending through the port. The recessed portion includes an opening to the chamber, and the opening is spaced from the port in a first direction. The wall includes a vent to the chamber, and the vent is spaced from the recessed portion in the first direction.
1 . A sensor assembly comprising:
a housing including a wall, the wall including a recessed portion, the recessed portion including a port, the housing defining a chamber;
a sensor positioned in the chamber and having a field of view extending through the port; and
a nozzle aimed at the sensor;
wherein the recessed portion includes an opening to the chamber, the opening spaced from the port in a first direction; and
wherein the wall includes a vent to the chamber, the vent spaced from the recessed portion in the first direction.
2 . The sensor assembly of claim 1 , wherein the recessed portion includes an outer edge circumscribing the recessed portion, and the port is spaced from the outer edge.
3 . The sensor assembly of claim 1 , wherein the nozzle is positioned to discharge through the port.
4 . The sensor assembly of claim 1 , wherein the nozzle is positioned in the chamber.
5 . The sensor assembly of claim 1 , further comprising a blower positioned to supply pressurized air to the nozzle.
6 . The sensor assembly of claim 5 , wherein the blower is positioned to draw in air from the chamber.
7 . The sensor assembly of claim 6 , wherein the blower includes a blower inlet, and the blower inlet is positioned in the chamber.
8 . The sensor assembly of claim 5 , further comprising a duct positioned to receive pressurized air from the blower and extending through the chamber to the nozzle.
9 . The sensor assembly of claim 1 , wherein the first direction is a horizontal direction.
10 . The sensor assembly of claim 1 , wherein the housing is shaped to be attachable to a body panel of a vehicle.
11 . The sensor assembly of claim 10 , wherein the first direction is a vehicle-forward direction relative to the vehicle when the housing is attached to the body panel of the vehicle.
12 . The sensor assembly of claim 11 , wherein the vent faces in the vehicle-forward direction when the housing is attached to the body panel of the vehicle.
13 . The sensor assembly of claim 11 , wherein the opening faces away from the vehicle-forward direction when the housing is attached to the body panel of the vehicle.
14 . The sensor assembly of claim 1 , wherein the sensor defines an axis at a center of the field of view of the sensor, and the sensor is positioned to define a gap along the axis between the sensor and the port.
15 . The sensor assembly of claim 14 , wherein the gap extends along the port opposite the first direction from the opening.
16 . The sensor assembly of claim 14 , wherein the gap is open to the chamber.
17 . The sensor assembly of claim 14 , wherein the nozzle is positioned in the gap.
18 . A sensor assembly comprising:
a housing including a wall, the wall including a recessed portion, the recessed portion including a port, the housing defining a chamber; and
a sensor positioned in the chamber and having a field of view extending through the port;
wherein the recessed portion includes an opening to the chamber, the opening spaced from the port in a first direction;
wherein the wall includes a vent to the chamber, the vent spaced from the recessed portion in the first direction;
wherein the recessed portion includes an outer edge circumscribing the recessed portion; and
wherein the port is spaced from the outer edge.
19 . The sensor assembly of claim 18 , wherein the opening is spaced from the outer edge.
20 . The sensor assembly of claim 18 , wherein the recessed portion extends into the chamber from the outer edge to the port.
