Abstract

The disclosed inventive concept provides a vertically articulating trailer hitch assembly for use with a vehicle, and particularly for use with an autonomous vehicle. The trailer hitch assembly is pivotally attached to the vehicle frame. The hitch assembly is allowed to swing away from the vehicle frame from a lowered position in which the trailer ball is uncoupled from the hitch coupler of the trailer to a raised position in which the trailer ball is coupled to the hitch coupler. The hitch assembly typically includes a receiver that has a long axis. The vehicle frame has a long axis. When the hitch assembly is in its lowered position, the long axis of the receiver is out of alignment with the long axis of the frame. When the hitch assembly is in its raised position, the long axis of the receiver is aligned with the long axis of the frame.

First claim

What is claimed is:

1. A height adjustable trailer hitch assembly for connecting a trailer hitch coupler to a towing vehicle having a frame having a long axis, the assembly comprising:
a receiver assembly including a receiver and a latch capture pawl having a hook portion; and
a receiver attachment assembly including a lateral tube for pivotally attaching said receiver assembly to the frame,
wherein said receiver assembly is movable between positions of axial alignment and non-alignment with the long axis of the frame,
wherein said latch capture pawl is pivotally attached to said lateral tube.

2. The height adjustable trailer hitch assembly of claim 1 in which said lateral tube is perpendicular to the long axis of the vehicle frame.

3. The height adjustable trailer hitch assembly of claim 1 further including an electric motor and rod assembly for moving said receiver assembly between said positions of axial alignment and non-axial alignment.

4. The height adjustable trailer hitch assembly of claim 1 , wherein said latch capture pawl locks said receiver assembly in said position of axial alignment.

5. The height adjustable trailer hitch assembly of claim 4 in which said receiver assembly includes a ball mount pin and clip assembly.

6. The height adjustable trailer hitch assembly of claim 1 further including a pawl capture shaft attached to said receiver, said latch capture pawl being engageable with said pawl capture shaft.

7. The height adjustable trailer hitch assembly of claim 6 further including a safety latch handle for manually releasing said latch capture pawl from said pawl capture shaft.
