US Patent 10351005 Vehicle charging system

A charge system includes a base, a platform including a projecting plug, at least three interlinked legs, and a first and second sets of articulating joints. The at least three interlinked legs are of a fixed same length and are mechanically biased to be perpendicular to the base. The first and second sets of articulating joints respectively connect opposite ends of the legs with the platform and base such that, responsive to a force on the plug, the legs tilt while remaining parallel to each other and the platform remains parallel with the base.
