1. A bodywork support structure for a vehicle, comprising:
two side sills that are spaced apart from each other in a transverse direction of the vehicle, wherein each of the two side sills respectively have a hollow space that is delimited outwards in the transverse direction of the vehicle by an external wall, inwards in the transverse direction of the vehicle by an internal wall, upwards in a vertical direction of the vehicle by an upper flange and downwards in the vertical direction of the vehicle by a lower flange and wherein a reinforcing element is disposed in the hollow space which is formed separately from the respective side sill;
a floor is disposed between the two side sills and connected to the two side sills; and
an energy store for storing electrical energy and/or a fuel for powering the vehicle is disposed under the floor;
wherein the reinforcing element is formed as a corner reinforcement disposed in a corner area delimited by the lower flange and by the external wall, wherein the corner reinforcement extends across a corner, wherein the corner reinforcement has a first connection area that is attached to the external wall, a second connection area that is attached to the lower flange, and a wall area that extends in the transverse direction of the vehicle and in the vertical direction of the vehicle and across the corner and connects the first and second connection areas with each other across the corner, and wherein the corner reinforcement is spaced apart from the upper flange in the vertical direction of the vehicle and from the internal wall in the transverse direction of the vehicle such that an open space is formed between the corner reinforcement and the internal wall in the transverse direction of the vehicle.
