Abstract

The disclosure relates to a battery carrier for accommodating at least one electric battery module in a vehicle. The battery carrier may include at least one first wall, at least one second wall arranged at an angle with respect to the first wall, wherein the second wall is joined to the first wall by a joining region, wherein an adhesive region is formed in the joining region, and the adhesive region is configured to condition the joining region for a materially bonded connection to a seal, and at least one seal materially bonded to the adhesive region in order to fluidically seal the joining region.

First claim

What is claimed is:

1. A battery carrier for accommodating at least one electric battery module in a vehicle, with:
at least one first wall comprising a carrier bottom or a carrier cover;
at least one second wall comprising at least one side wall, wherein the at least one second wall is arranged at a non-parallel angle with respect to the at least one first wall, wherein the second wall is joined to the first wall by a joining region and laterally limits the at least one first wall, wherein an adhesive region is formed in the joining region; and
at least one seal materially bonded to the adhesive region to fluidically seal the joining region, wherein the adhesive region is configured to condition the joining region for a materially bonded connection to the at least one seal.

2. The battery carrier according to claim 1 , further comprising:
at least one third wall comprising the carrier bottom or the carrier cover, different from the at least one first wall, wherein the at least one side wall laterally limits the at least one third wall, and wherein the at least one side wall is joined to the carrier bottom by the joining region.

3. The battery carrier according to claim 1 , wherein the at least one side wall comprises a first side wall, wherein at least one second wall comprises at least an additional side wall, and wherein the first side wall is joined to the additional side wall by the joining region.

4. The battery carrier according to claim 1 , wherein:
the adhesive region comprises an adhesive layer, wherein the adhesive layer comprises at least one of: a plastic layer, a silane layer, a metalorganic layer, a titanium-zirconium layer, and an anodized layer; and
the adhesive region comprises one or more of: a plasma-cleaned region or a laser-cleaned region.

5. The battery carrier according to claim 1 , wherein the joining region comprises a welded connection or a soldered connection.

6. The battery carrier according to claim 1 , wherein the joining region comprises at least one of: a rivet connection, a screw connection, and a clinch connection.

7. The battery carrier according to claim 1 , wherein the joining region comprises a joining connection between the at least one first wall and the at least one second wall, and wherein the adhesive region is formed on the joining connection.

8. The battery carrier according to claim 1 , wherein the joining region is formed at least in sections between the at least one first wall and the at least one second wall.

9. The battery carrier according to claim 1 , wherein the seal is formed from at least one elastomer, or from a single-component or a two-component melt or epoxy resin adhesive applied in the form of a paste.

10. The battery carrier according to claim 1 , wherein the at least one second wall is formed with a side wall lower side, wherein the at least one first wall is formed as the carrier bottom with a bottom upper side, wherein the side wall lower side is placed onto the bottom upper side to connect the side wall to the carrier bottom.

11. The battery carrier according to claim 10 , wherein the adhesive region is formed between the carrier bottom and a side wall inner side of the side wall that faces the battery carrier or between the carrier bottom and a side wall outer side of the side wall that faces away from the battery carrier.

12. The battery carrier according to claim 1 , wherein the at least one second wall extends at a right angle with respect to the at least one first wall.

13. The battery carrier according to claim 1 , wherein:
the at least one second wall or the at least one first wall, or both is/are formed as a single piece; or
the at least one second wall or the at least one first wall, or both, comprise(s) aluminum.

14. The battery carrier according to claim 1 , wherein the at least one first wall comprises the carrier bottom, wherein the side wall frame comprises at least four side walls that laterally limit the carrier bottom and are joined to the carrier bottom by joining regions, wherein the joining regions includes the joining region, wherein the adhesive region is formed in the joining regions that is configured to condition the respective joining region, and wherein the battery carrier comprises at least four seals.

15. A method for producing a battery carrier for accommodating at least one electric battery module in a vehicle, wherein the method comprises:
joining of at least one second wall comprising at least one side wall to at least one first wall by a joining region, wherein the second wall is arranged at a non-parallel angle with respect to the first wall, wherein the at least one first wall comprises a carrier bottom or a carrier cover, and wherein the at least one second wall laterally limits the at least one first wall;
forming of an adhesive region in the joining region to condition the joining region for a materially bonded connection to a seal, and
material bonding of the seal to the adhesive region to fluidically seal the joining region.

16. The method according to claim 15 , further comprising:
applying an adhesive layer in the joining region to form the adhesive region, and wherein the adhesive layer comprises at least one of: a plastic layer, a silane layer, a metalorganic layer, a titanium-zirconium layer, and an anodized layer.

17. The method according to claim 15 , further comprising:
forming the adhesive region in the joining region by one or more of: plasma cleaning method or laser cleaning.

18. A battery carrier for accommodating at least one electric battery module in a vehicle, with:
at least one first wall configured as a carrier bottom;
at least one second wall arranged at a non-parallel angle with respect to the first wall, wherein the second wall is joined to the first wall by a joining region, wherein an adhesive region is formed in the joining region, and the adhesive region is configured to condition the joining region for a materially bonded connection to a seal; and
at least one seal materially bonded to the adhesive region to fluidically seal the joining region, wherein the second wall is configured as a side wall with a side wall inner side, wherein a flange is arranged on the side wall inner side, wherein the carrier bottom is placed onto the flange to connect the side wall to the carrier bottom, and wherein the adhesive region is formed between the carrier bottom and the side wall inner side that faces the battery carrier.

19. The battery carrier according to claim 18 , wherein the adhesive region comprises an adhesive layer, wherein the adhesive layer comprises at least one of: a plastic layer, a silane layer, a metalorganic layer, a titanium-zirconium layer, and an anodized layer, and wherein the adhesive region comprises one or more of: a plasma-cleaned region or a laser-cleaned region.

20. The battery carrier according to claim 18 , wherein the seal is formed from at least one elastomer, or from a single-component or a two-component melt or epoxy resin adhesive applied in the form of a paste.
