Vehicle sensor assembly
An assembly includes a base. The assembly includes an object detection sensor. The assembly includes a deflector extending upward from the base in front of the object detection sensor. The deflector is configured to direct ram air away from the object detection sensor. The assembly includes a nozzle supported by the deflector and aimed at the object detection sensor.
1. An assembly comprising:
a base;
an object detection sensor;
a deflector extending upward from the base in front of the object detection sensor, the deflector configured to direct ram air away from the object detection sensor, the deflector including a first deflection surface configured to direct ram air up and right of the object detection sensor and a second deflection surface configured to direct ram air up and left of the object detection sensor; and
a nozzle supported by the deflector and aimed at the object detection sensor.
2. The assembly of claim 1 , wherein the first deflection surface and the second deflection surface are concave.
3. The assembly of claim 1 , wherein the deflector includes a rear surface, the nozzle at the rear surface.
4. The assembly of claim 3 , wherein the rear surface has a peak, the nozzle at the peak.
5. The assembly of claim 4 , wherein the deflector includes a top edge that extends from a front of the deflector to the peak.
6. The assembly of claim 1 , wherein the deflector is spaced from the object detection sensor along a vehicle longitudinal axis.
7. The assembly of claim 6 , wherein the deflector is elongated along the vehicle longitudinal axis.
8. The assembly of claim 7 , wherein the deflector includes a top edge extending along the vehicle longitudinal axis.
9. The assembly of claim 8 , wherein the top edge is convex.
