Battery carrier for an electric motor vehicle
The present invention relates to a battery carrier for an electric motor vehicle, having a tray 1 having a base 2 and a peripheral wall which protrudes from the base and a flange 4 which protrudes from the wall so as to be orientated in an outward direction, characterized in that the tray 1 is integrally produced as a folding component and in a materially integral manner from a plate 6 , wherein in at least one the corner region 8 of the peripheral wall there is formed on a side wall 3 at least one joining plate 5 which overlaps the adjacent side wall 3 and the joining plate 5 and the adjacent side wall 3 are joined to each other.
1. A battery carrier for an electric motor vehicle, the battery carrier comprising a tray having:
a base;
a peripheral wall which protrudes from the base and which includes a plurality of side walls coupled to each other;
a flange which protrudes from the peripheral wall in an outward direction; and
in at least one corner region of the peripheral wall, at least one joining plate which is formed on a side wall among the plurality of side walls and overlaps an adjacent side wall among the plurality of side walls,
wherein the flange extends along an entire perimeter of the tray,
wherein the tray is integrally produced as a folding component and in a materially integral manner from a plate, and
wherein the joining plate and the adjacent side wall are joined to each other by welding in combination with a sealing agent or sealing material between the joining plate and the adjacent side wall.
2. A battery carrier according to claim 1 , wherein the joining plate and the adjacent side wall are joined to each other by a thermal joining seam, weld seam, and/or adhesive.
3. A battery carrier according to claim 2 , wherein the thermal joining seam is a continuous weld seam.
4. A battery carrier according to claim 1 , wherein the joining plate, with respect to an inner space of the tray, overlaps the adjacent side wall at an outer side.
5. A battery carrier according to claim 1 , wherein the flange in a respective corner region of two adjacent side walls is coupled as a projected extension of a side wall, by a thermal joining seam, parallel to the base, or extends outward at a 45° angle by a thermal joining seam.
6. A battery carrier according to claim 1 , wherein the plate the tray is produced from is a metal plate.
7. A battery carrier according to claim 1 , further comprising, in the tray, reinforcement struts configured to receive batteries arranged in the tray.
8. A battery carrier according to claim 1 , wherein the plate the tray is produced from is made of steel having a tensile strength Rm greater than 600 MPa.
9. A battery carrier according to claim 1 , wherein the base and/or the side walls have embossings for reinforcement.
10. A battery carrier according to claim 1 , wherein the plate the tray is produced from is a steel plate.
11. A battery carrier according to claim 1 , wherein the plate the tray is produced from is made of an aluminum alloy in a rolled state with a tensile strength Rm greater than 250 MPa.
12. A battery carrier according to claim 1 , wherein the joining plate, with respect to an inner space of the tray, overlaps the adjacent side wall at an inner side.
