Abstract

Battery carrier for an electric motor vehicle, having a trough formed by a base and a peripheral frame coupled to the base, wherein the frame is formed from extruded hollow profiles and a cover is arranged on the frame. In the installation position, the frame has a web protruding in each case in relation to its upper side and/or lower side in such a manner that a defined gap with respect to the base and/or with respect to the cover is produced, with a sealant and/or adhesive being incorporated.

First claim

The invention claimed is:

1. Battery carrier for an electric motor vehicle, having a trough formed by a base and a peripheral frame coupled to the base, wherein the frame is formed from extruded or roll-formed hollow profiles and a cover is arranged on the frame, wherein, in the installation position, the frame has a web protruding in each case in relation to its upper side or lower side in such a manner that a defined gap with respect to the base or with respect to the cover is produced, with a sealant or adhesive being incorporated.

2. Battery carrier according to claim 1 , wherein a base plate is provided, with a cooling system arranged therebelow in the installation direction.

3. Battery carrier according to claim 2 , wherein a cooling duct plate is arranged below the base plate in such a manner that a cooling duct system is formed between base plate and cooling duct plate.

4. Battery carrier according to claim 2 , wherein hollow profiles running transversely with respect to the direction of travel are arranged below the base plate.

5. Battery carrier according to claim 1 , wherein a cover is arranged on the frame, wherein the cover has a peripheral flange and rests with the flange on the frame.

6. Battery carrier according to claim 5 , wherein the flange of the cover has a collar or step which engages downwards around the frame and with which the flange engages over the frame.

7. Battery carrier according to claim 1 , wherein the frame is welded tightly together in the corner regions by a peripheral weld seam.

8. Battery carrier according to claim 1 , wherein the frame profiles are tightly joined at least in a corner by electric resistance fusion welding.

9. Battery carrier according to claim 1 , wherein two adjacent frame profiles have a notch in at least one corner region in such a manner that two frame profiles engage in each other in the corner region and the outer wall of one of the frame profiles closes an end side of the other frame profile.

10. Battery carrier according to claim 1 , wherein two adjacent frame profiles have a miter cut in a corner region in such a manner that two end sides of the frame profiles butt against each other.

11. Battery carrier according to claim 1 , wherein mounting holders for coupling to batteries are arranged in the frame or on an inner side of the frame.

12. Battery carrier according to claim 1 , wherein the base plate and optionally the cooling duct plate are reached through from below by a screw bolt, wherein the screw bolt is screwed into the hollow profile of the frame.

13. Battery carrier according to claim 1 , wherein the frame in cross section has grooves or predetermined buckling points in such a manner that the frame acts as a crash box during a side impact.

14. Battery carrier according to claim 2 , wherein hollow profiles running transversely with respect to the direction of travel are arranged below the cooling duct plate.

15. Battery carrier according to claim 1 , wherein the frame profiles are tightly joined at least in a corner by resistance pressure welding.

16. Battery carrier according to claim 1 , wherein the frame profiles are tightly joined at least in a corner by flash butt welding.
