1. An aerodynamic structure for a cargo body comprising:

  • a side panel hingedly mounted on a door of the cargo body;

    an upper panel hingedly mounted on the door of the cargo body that, together with the side panel, defines an internal cavity when the aerodynamic structure is in a deployed position, the upper panel including a diagonal hinge line that defines a first foldable section and a second foldable section, the upper panel being directly hingedly connected to the side panel;

    wherein the upper panel and the side panel are constructed and arranged to automatically collapse into a folded position when the door is opened and moved toward an outer side of the cargo body and the side panel engages the outer side of the cargo body, causing the aerodynamic structure to collapse automatically; and

    a linkage assembly mounted on the door and interconnected to the upper panel, the linkage assembly being secured at a first end to the upper panel and at a second end to the door, so as to provide rigidity for the upper panel, the linkage assembly biasing the upper panel open when the aerodynamic structure is in the deployed position, and the biasing of the upper panel is overcome when the side panel engages the outer side of the cargo body.
