Abstract

Claims (61)

1 . A structural component that serves as a container for a vehicle, comprising:

a trough-shaped container section forming a compartment and defining a bottom region and two or more wall regions, which are at least sectionally inclined with respect to the bottom region,

an edge region,

wherein the two or more wall regions are arranged between the bottom region and the edge region,

fastening elements that are provided in the edge region,

wherein the fastening elements are arranged and distributed around the container section,

wherein the container section and the edge region are formed of an injection moldable fiber reinforced thermoplastic material, and

wherein the structural component at least sectionally has a porous internal structure that is formed by foaming the thermoplastic material.

2 . The structural component of claim 1 ,

wherein the edge region is in arranged as a circumferential edge region that surrounds the two or more wall regions.

3 . The structural component of claim 1 ,

wherein the two or more wall regions extend between the bottom region and the edge region, and

wherein the edge region is configured at least in part as a collar that projects outwardly from the container section.

4 . The structural component of claim 1 ,

wherein the bottom region is offset from the edge region in a main demolding direction.

5 . The structural component of claim 1 ,

wherein the structural component is manufactured by an open-close mold.

6 . The structural component of claim 1 , comprising a circumferential sealing portion adjacent to an upper end of the container section.

7 . The structural component of claim 1 ,

wherein the fastening elements in the edge region are selected from the group consisting of: adhesive surfaces, mounting holes, domes, protrusions, recesses, and mounting tabs.

8 . The structural component of claim 1

wherein at least one wall region of the two or more wall regions of the container section is stepped and includes a support region extending approximately parallel to the bottom region.

9 . The structural component of claim 8 ,

wherein at least one fastening element is formed in the support region of the at least one wall region,

wherein the at least one fastening element in the support region is selected form the group consisting of a raised fastening element, a recessed fastening element, and an adhesive surface.

10 . The structural component of claim 1 ,

wherein the two or more wall regions of the container section form a front wall, a rear wall, and first and second side walls, and

wherein the front wall is offset from the rear wall in a direction of travel of the vehicle.

11 . The structural component of claim 1 ,

wherein the bottom region of the container section extends substantially horizontally, and

wherein the edge region, defines a plane that is at least approximately inclined with respect to the horizontal and that is inclined downwardly in the direction of travel.

12 . The structural component of claim 1 ,

wherein at least one wall region of the two or more wall regions of the container section comprises stiffening elements that are demoldable in a main demolding direction, and

wherein the stiffening elements are arranged in the form of at least one of beads and ribs having a vertical longitudinal extension.

13 . The structural component of claim 1 ,

wherein the structural component is made at least proportionally from a recyclate material.

14 . The structural component of claim 1 ,

wherein the structural component is made at least proportionally from an engineered biopolymer.

15 . The structural component of claim 1 ,

wherein the structural component has a density that is reduced by means-of-negative embossing.

16 . The structural component of claim 1 ,

wherein the bottom region is designed to be at least sectionally flat and provided with a stiffening structure having a plurality of stiffening elements, and

wherein the stiffening elements are arranged in the form of at least one of ribs and beads.

17 . The structural component of claim 1 ,

wherein a stiffening structure is formed in the edge region and adjacent to a fastening element.

18 . The structural component of claim 16 ,

wherein the stiffening structure has ribs that are demoldable in the main demolding direction, and

wherein the ribs are formed on an underside of the bottom region.

19 . The structural component of claim 16 ,

wherein the stiffening structure comprises at least one bionic design engineered pattern having multiple stiffening elements.

20 . The structural component of claim 19 ,

wherein the bionic design engineered pattern is selected from the group of formations consisting of: spider web, bamboo stalk, water lily leaf blade, mushroom lamella, turtle shell, honeycomb, limpet shell, diatoms, and combinations thereof.

21 . The structural component of claim 19 ,

wherein the stiffening structure at the bottom region comprises a central portion having a first bionic design engineered pattern and outer portions adjacent to the central portion having a second bionic design engineered pattern.

22 . The structural component of claim 20 ,

wherein a first bionic design engineered pattern is provided in the central portion, wherein the design of the first bionic design engineered pattern is based on a turtle shell, and

wherein a second bionic design engineered pattern is provided in the outer regions, wherein the design of the second bionic design engineered pattern is based on mushroom lamellae or a spider web.

23 . The structural component of claim 1 ,

wherein the structural component is configured as one of a rear trunk pan, a front trunk pan, a spare wheel pan, and a control unit housing.

24 . The structural component of claim 1 ,

wherein the structural component reinforces a body-side crash structure of the vehicle.
