Abstract
An electric vehicle body structure includes an installation space being downwardly open and upwardly delimited by a floor body-panel profile section. A traction battery is inserted into the space from below, a battery housing flange under the profile section is screwed from below to the profile section at a screw connection having a vertical screw bolt penetrating a housing flange passage and screw hole in the profile section and screwed to a weld nut at a flange housing opposite side of the profile section. The flange is clamped between screw bolt head and profile section. A crash displaces the battery until an inner passage wall presses screw bolt against screw hole edge, subjecting the screw bolt to shear load reduced by an elongated weld nut shaft projecting into the screw hole. The screw bolt presses against the screw hole edge, with the weld nut shaft in intermediate position.
