Abstract
The present disclosure relates to a reinforcing structure for reinforcing a side wall structure for a motor vehicle in the region of a door cutout, wherein the reinforcing structure is designed ring-shaped in order to surround a door cutout of a side wall structure. It is provided that the reinforcing structure is produced material-uniformly. The present disclosure furthermore relates to a semi-finished product for producing such a reinforcing structure and to a method for producing the reinforcing structure. The present disclosure also relates to a side wall structure and to a side wall for a motor vehicle.
Claims20
A reinforcing structure for reinforcing a side wall structure for a motor vehicle in the region of a door cutout, wherein the reinforcing structure is ring-shaped in order to surround the door cutout of the side wall structure, and the reinforcing structure at least partially consists of a press-hardened steel or a press-hardened steel alloy.
A semi-finished product for producing a reinforcing structure that is produced from at least one blank and forms a ring structure couplable to a side wall structure of a motor vehicle in order to surround a door cutout formed in the side wall structure.
A method for producing a reinforcing structure comprising:
- providing a plurality of blanks;
- connecting the plurality of blanks to one another subject to forming a ring structure, so that a semi-finished product is formed;
- and
- creating a reinforcing structure through hot-forming of the semi-finished product without its prior cold-forming or through cold-forming of the semi-finished product and subsequent hot-forming of the cold-formed semi-finished product, so that the portions of the reinforcing structure are produced out of the plurality of blanks of the semi-finished product.
A motor vehicle comprising:
- a side wall having a door cutout;
- and
- a reinforcing structure that is ring-shaped in order to surround the door cutout of the side wall structure, the reinforcing structure having at least two portions, of which at least one of the at least two portions in its material thickness is distinct from at least one other one of the at least two portions.
