Abstract

A rear passenger seat air ventilation system for an electric vehicle includes a rigid tunnel positioned within a passenger compartment of the electric vehicle. The rigid tunnel covers a portion of a battery assembly that extends above a floor structure of the electric vehicle such that the passenger compartment is sealed from the battery assembly. The rigid tunnel defines a forward opening and a rear opening connected by a conduit extending along at least a portion of a length of the rigid tunnel. The conduit is disposed within an interior of the rigid tunnel. A center console is positioned above at least a portion of the rigid tunnel. An air supply system interfaces with the forward opening and to deliver air to the conduit. At least one air vent receives air from the conduit and deliver the air to a rear seating area of the passenger compartment.

First claim

What is claimed is:

1. A rear passenger seat air ventilation system for an electric vehicle, comprising:
a rigid tunnel positioned within a passenger compartment of the electric vehicle, the rigid tunnel being configured to cover a portion of a battery assembly that extends above a floor structure of the electric vehicle such that the passenger compartment is sealed from the battery assembly, wherein:
the rigid tunnel slopes downward from a forward portion to a rear portion of the rigid tunnel;
a top surface of the rigid tunnel defines a forward opening and a rear opening connected by a conduit extending along at least a portion of a length of the rigid tunnel; and
the conduit is disposed within an interior of the rigid tunnel;
a center console positioned above at least a portion of the rigid tunnel;
an air supply system positioned within the center console and configured to interface with the forward opening and to deliver air to the conduit; and
at least one air vent configured to receive air from the conduit and deliver the air to a rear seating area of the passenger compartment.

2. The rear passenger seat air ventilation system for an electric vehicle of claim 1 , further comprising:
a manifold coupled between the rear opening and the at least one air vent, the manifold being configured to direct the air from the conduit into the at least one air vent.

3. The rear passenger seat air ventilation system for an electric vehicle of claim 2 , wherein:
the at least one air vent comprises an upper vent configured to deliver the air to the rear seating area at a height near a rear seating surface and a lower vent configured to deliver the air to the rear seating area at a position proximate a floor of the rear seating area.

4. The rear passenger seat air ventilation system for an electric vehicle of claim 1 , wherein:
the air supply system comprises one or both of an air conditioner and a heater.

5. The rear passenger seat air ventilation system for an electric vehicle of claim 1 , wherein:
the conduit and the rigid tunnel comprise carbon fiber.

6. The rear passenger seat air ventilation system for an electric vehicle of claim 1 , wherein:
the conduit comprises pressed aluminum.

7. The rear passenger seat air ventilation system for an electric vehicle of claim 1 , wherein:
one or both of the rigid tunnel or the conduit comprises thermal insulation.
