Tesla patents car doors that act as structural frame parts

Patent drawing
Patent drawing from the official filing.

Tesla has filed a patent for a vehicle design where the exterior door panels are made from a single, solid piece of metal that acts as part of the car's main structural frame. This design allows components like the electric window assembly to be attached directly to the door panel, which then transfers the load to the vehicle's frame through the hinge.

Why it mattersThis approach could simplify car manufacturing by reducing the number of separate parts needed for the door structure, potentially improving crash resistance by integrating the door directly into the vehicle's exoskeleton.

In the filing’s own words

A vehicle having an exoskeleton exterior panel that provides crash resistance is described. The exterior panel may be formed from a monolithic metal sheet and attached to an exterior portion of the vehicle frame, and the exterior panel does not comprise an additional support structure. At least one component may be directly attached to the exterior panel, and the exterior panel may bear the load of the at least one component. Methods of manufacturing the vehicle are also described.

What exactly they claim (claim 1)

1. A vehicle, comprising: a vehicle frame comprising an exterior portion; an exterior door panel comprising a monolithic metal sheet having a continuous uninterrupted exterior, the exterior door panel forming a structural part of an exoskeleton of the vehicle and being fixedly and directly coupled to the exterior portion of the vehicle frame through a hinge; an electric window assembly fixedly and directly coupled to the exterior door panel; wherein the exterior door panel provides primary structural support for the electric window assembly and defines a structural load path extending from the electric window assembly through the exterior door panel to the vehicle frame via the hinge.
