Problems solved by technology

Due to this very individual adaptation of the housing parts to the respective vehicle, problems can arise in assembly, so that different housings require different production sequences and therefore no uniform production concept can be used

Embodiment Construction

[0016] In the case of a high-voltage accumulator housing for a passenger car, the lower housing part 1 and the support structure 2 are shown separately in a perspective exploded view in the single figure. In this case, the high-voltage storage housing can be arranged in the underbody region of the vehicle, ie essentially between the respective side sills.

[0017] In this case, the housing part 1 is configured in the shape of a pot or shell and is produced, for example, by a forming process of a metal sheet, in particular an aluminum sheet or a steel sheet. As an alternative to this, the housing part 1 can also be designed, for example, as a plastic part, in particular a fiber-reinforced plastic component, which can be produced, for example, by compression molding (SMC) or injection molding (RTM). The housing part 1 has a sealing element 3 in the form of a flange 4 , which optionally supplements sealing means, seals or the like, by means of which the housing part 1 can be seal...

Abstract

The invention relates to a high-voltage energy store housing for a motor vehicle, having at least one housing part (1), which is reinforced by a frame structure (2) having respective frame structure elements (5, 6, 7, 8). The frame structure (2) is designed as a structural unit (13) formed separately from the housing part (1) to create a high-voltage energy store housing which, for example, can be better adapted to different vehicles or battery cells and battery modules.

Description

technical field [0001] The invention relates to a high-voltage storage housing for a motor vehicle according to the preamble of claim 1 . Background technique [0002] A high-voltage accumulator housing for a motor vehicle, in particular for a high-voltage accumulator housing arranged in the area of ​​the floor, usually consists of several, in particular two, housing parts which are connected to each other in the area of ​​the flange. connect. In this context, two requirements have hitherto been placed in particular on previous housing parts: On the one hand, the corresponding battery module or battery cell is thus accommodated in a hermetically sealed manner with respect to the surrounding environment. On the other hand, the corresponding housing part has a load-bearing structure in order to give the entire high-voltage store or the housing of the high-voltage store sufficient stability. For this reason, the corresponding housing parts, usually produced from sheets and pr...
