Abstract

The disclosure describes a battery tray profile for a battery tray that holds at least one electric battery module of a vehicle. The battery tray profile includes a base plate configured to receive the at least one electric battery module, wherein the base plate comprises at least one extruded curve; and a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate. The disclosure also describes a method for producing a battery tray profile for a battery tray, including extruding a base plate for receiving the electric battery module; extruding at least one curve in the base plate; extruding a hollow profile wall that rises from the base plate and is integrally extruded with the base plate; and obtaining the battery tray profile from the extruding of the base plate and the hollow profile wall during an extrusion process.

First claim

The invention claimed is:

1. A battery tray profile for a battery tray that holds at least one electric battery module of a vehicle, comprising:
a base plate configured to receive the at least one electric battery module, wherein the base plate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched; and
a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate;
wherein the base plate comprises at least one extruded fold comprising the at least one extruded curve, wherein the extruded fold is configured to stretch into an arc shape, or wherein the base plate is curved into an arc shape.

2. The battery tray profile according to claim 1 , wherein the at least one extruded curve is configured to stretch into a flat receiving surface configured to receive the electric battery module.

3. The battery tray profile according to claim 1 , wherein a plurality of the extruded folds comprise parallel extrusions.

4. A battery tray profile for a battery tray that holds at least one electric battery module of a vehicle, comprising:
a base plate configured to receive the at least one electric battery module, wherein the base plate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched; and
a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate, wherein the hollow chamber wall delimits a receiving region on the base plate configured to receive the electric battery module, or wherein the hollow chamber wall laterally delimits the base plate as a side frame.

5. A battery tray profile for a batter tray that holds at least one electric battery module of a vehicle, comprising:
a base elate configured to receive the at least one electric battery module, wherein the base olate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched; and
a hollow chamber wall that rises from the base olate and is integrally extruded with the base plate; and
an additional hollow chamber wall that rises from the base plate or laterally delimits the base plate or divides the base plate, wherein the hollow chamber wall and the additional hollow chamber wall are arranged on opposing edges of the base plate or are arranged at a right angle to one another.

6. The battery tray profile according to claim 5 , wherein the hollow chamber wall and the additional hollow chamber wall each comprise at least one hollow channel.

7. The battery tray profile according to claim 6 , wherein the at least one hollow channel is superimposed.

8. The battery tray profile according to claim 5 , wherein the hollow chamber wall and the additional hollow chamber wall each comprise at least one hollow projection that extends along the respective hollow chamber wall and is remote from the base plate.

9. The battery tray profile according to claim 1 , wherein the hollow chamber wall and the additional hollow chamber wall each extend in a straight line or are configured to be bent around corner edges of the base plate.

10. A battery tray profile for a battery tray that holds at least one electric battery module of a vehicle, comprising:
a base plate configured to receive the at least one electric battery module wherein the base plate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched; and
a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate;
wherein the base plate is formed from a solid material or is formed as part of a sandwich structure that is joined in a fluid tight manner or as a hollow profile base plate comprising a plurality of hollow channels.

11. The battery tray profile according to claim 10 , wherein a fluid is configured to flow through the plurality of hollow channels to control the temperature of the electric battery tray.

12. A battery tray profile for a battery tray that holds at least one electric battery module of a vehicle, comprising:
a base plate configured to receive the at least one electric battery module, wherein the base plate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched; and
a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate, having at least two different wall thicknesses in the hollow chamber wall and an additional hollow chamber wall or in the base plate.

13. The battery tray profile according to claim 1 , wherein the base plate of the battery tray profile is stretched at least in part.

14. The battery tray profile according to claim 13 , comprising at least two additional hollow chamber walls that rise from the base plate, wherein the hollow chamber walls and the at least two additional hollow chamber walls form a peripheral side frame of the battery tray.

15. A battery tray arrangement, comprising:
a battery tray profile comprising a base plate configured to receive at least one electric battery module, wherein the base plate comprises at least one extruded curve, wherein the at least one extruded curve is configured to be stretched, and a hollow chamber wall that rises from the base plate and is integrally extruded with the base plate;
an additional battery tray profile comprising an additional base plate and at least one additional hollow chamber wall, wherein the base plate of the battery tray profile and the additional base plate of the additional battery tray profile form a common base plate, wherein the at least one additional hollow chamber wall rise from the common base plate, and wherein the battery tray comprises a peripheral side frame that is formed by the hollow chamber wall and the at least one additional hollow chamber wall.

16. The battery tray arrangement according to claim 15 , further comprising:
a heat exchanger configured to allow a fluid to flow through and to control the temperature of an electric battery module, wherein the heat exchanger is connected to the base plate of the battery tray.

17. A method for producing a battery tray profile for a battery tray that holds at least one electric battery module of a vehicle, comprising:
extruding a base plate for receiving the electric battery module;
extruding at least one curve in the base plate, wherein the at least one extruded curve is configured to be stretched;
extruding a hollow profile wall that rises from the base plate and is integrally extruded with the base plate; and
obtaining the battery tray profile from the extruding of the base plate and the hollow profile wall during an extrusion process, wherein the hollow profile wall delimits a receiving region on the base plate configured to receive the electric battery module, or wherein the hollow chamber wall laterally delimits the base olate as a side frame.
