Claim 0:
1. A body structure for an electrically operated vehicle, the body structure comprising:
a bottom of the vehicle and a top of the vehicle defining a vehicle vertical direction, a vehicle floor sheet-metal part and a body-side sheet-metal profile part;
an installation space for a traction battery, said installation space being open in said vehicle vertical direction in a direction towards said bottom of the vehicle and delimited by said vehicle floor sheet-metal part in a direction towards said top of the vehicle, said installation space configured for insertion of the traction battery from beneath the vehicle;
a housing flange for the traction battery, said housing flange engaging beneath said sheet-metal profile part and being screwed to said sheet-metal profile part from beneath the vehicle at least at one screw position;
a weld nut welded to a side of said sheet-metal profile part facing away from said housing flange, said weld nut being extended by a shaft;
said screw position having a screw bolt being oriented in said vehicle vertical direction and having a screw head, said screw bolt being guided with hole play through a through-channel in said housing flange and through a screw hole in said sheet-metal profile part, said screw bolt being screwed to said weld nut for clamping said housing flange between said screw head of said screw bolt and said sheet-metal profile part;
in an event of a crash, the traction battery being displaced, as a result of the crash, until an inside wall of said housing flange through-channel presses said screw bolt against an opening rim of said sheet-metal profile part screw hole, with shear loading of said screw bolt;
said shaft of said weld nut projecting at least into said sheet-metal profile part screw hole to reduce the shear loading and, in the event of the crash, said screw bolt pressing against said opening rim of said sheet-metal profile part screw hole with an interposition of said weld nut shaft; and
said weld nut shaft protruding beyond a side of said sheet-metal profile part facing towards said housing flange, or said weld nut shaft projecting into said housing flange through-channel with a projection length, and in the event of the crash, said inside wall of said housing flange through-channel pressing against said screw bolt with an interposition of said weld nut shaft.
