An aerodynamic structure attached to the sides and top of a truck cargo body (either a stand-alone trailer or a 'straight truck' with the cab and cargo area as a fixed vehicle) at the aftmost region, which rear typically contains a rolling door assembly, which rolls upwardly. An aerodynamic structure is permanently attached to the sides and top of the trailer in a manner that extend past the aftmost plane of the truck cargo body and retract to the aftmost plane of the truck cargo body when subjected to a force, allowing this device to be backed into structures. The retracted orientation allows for the rear of the trailer to be fully accessible for loading and unloading, and does not reduce the size of the opening of the trailer. The various embodiments of the invention allow for automated deployment once the force used to compress the structure is removed.

Rear-mounted retractable aerodynamic structure for cargo bodies

A rear-mounted aerodynamic structure for securing to a cargo body includes a three- or four-sided structure having a deployed position for assisting in improving aerodynamic efficiency of the cargo body. The cargo body can be the body of a trailer of a tractor-trailer vehicle or trailer towed behind a vehicle such as a truck. It can comprise a trailer body or other cargo body well-known in the art. A spoiler 'flow keeper' mounted to a top surface of the rear of the cargo body, as additional aerodynamic structures or as a standalone spoiler for cargo bodies. The three- or four-sided rear-mounted aerodynamic structure can comprise any of a variety of illustrative embodiments shown and described herein.
