Embodiment Construction

[0033] Next, the present invention will be described in detail with reference to the drawings.

[0034] figure 1 A perspective view of a partial area of ​​the battery housing 1 is shown obliquely from above. It has a rectangular design overall. The battery housing has side walls 2 , 3 which are opposed in pairs. The side walls 2 and 3 are hollow cavity profiles whose cross section is image 3 shown in . They form the supporting frame of the battery housing 1 . The side walls 2 extending in the longitudinal direction L are different from the side walls 3 extending in the transverse direction Q. The height direction is represented by Z, as infigure 1 As can be seen from the coordinate system in . The illustrated battery housing 1 is open at the top and closed at the bottom by a bottom 4 . The bottom 4 is connected, in particular welded, to the side walls in the longitudinal direction L and in the transverse direction Q.

[0035] Inside the space enclosed by the side wall...

Abstract

The invention relates to a battery housing having a bottom 4, side walls 2 and inner transverse walls 5 connected to the bottom 4, wherein the side walls 2 have a connection with the bottom 4 Flanges 8 arranged at a distance and protruding towards the inner transverse wall 5 have openings 13 for the screwed connection of the insertable battery modules and between the bottom 4 and the flange 8 a thread is provided The carrier 10 , wherein the lugs 11 of the inner transverse wall 5 can be screwed via the lug openings 12 to the threaded carrier 10 and to the flange 8 .

Description

technical field [0001] The invention relates to a battery housing having a bottom, side walls and inner transverse walls connected to the bottom. Background technique [0002] In order to increase the resistance against external intrusion, battery housings for motor vehicles can be constructed with internal rib structures for reinforcement and reinforcement. These structures are connected in a materially bonded manner to the outer frame of the battery housing, ie to the side walls. Additional components can be used if manufacturing tolerances between the side walls and the rib-like structure are to be compensated. These components involve additional costs due to the outlay in production, delivery and joining. In order to achieve fusion welding applications of suitable quality, the weld seam must be welded, for example, in the flat welding position, especially if aluminum components are involved. In the case of multiple rib structures, frequent reorientation of the workpie...
