Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem Hochvoltspeicher nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle with a high-voltage storage according to the preamble of patent claim 1.

Im Internet unter http://www.atzonline.de/Aktueil/Nachrichten/1/13309/pr/print.html findet sich ein Artikel der ATZ Online über das Fahrzeug BMW Active E. In diesem Artikel wird ausgeführt, dass der BMW Active E über drei Hochvoltspeicher verfügt. Der größte Hochvoltspeicher nimmt den Platz des konventionellen Antriebsstrangs im unteren Bereich des Fahrzeugs ein. Zu ihrem Schutz ruhen die drei Hochvoltspeicher in speziell angefertigten Gehäusen.On the internet http://www.atzonline.de/Aktueil/Nachrichten/1/13309/pr/print.html There is an article in the ATZ Online about the BMW Active E vehicle. This article states that the BMW Active E has three high-voltage accumulators. The largest high-voltage accumulator takes the place of the conventional powertrain in the lower part of the vehicle. For their protection, the three high-voltage accumulators rest in custom-made enclosures.

Aufgabe der Erfindung ist es, ein Kraftfahrzeug mit einem Hochvoltspeicher zu schaffen, der möglichst gut vor Beschädigungen geschützt ist.The object of the invention is to provide a motor vehicle with a high-voltage storage, which is protected as well as possible from damage.

Diese Aufgabe wird mit einem Kraftfahrzeug mit einem Hochvoltspeicher mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a motor vehicle having a high-voltage storage with the features of patent claim 1.

Im Zuge der Elektrifizierung von Kraftfahrzeugen stellt sich die Frage nach einer optimalen Unterbringung des Hochvoltspeichers. Bauräume wie Sitzmulden, Tunnel und auch der gesamte Unterboden des Kraftfahrzeugs bieten sich hier als potentielle Bauräume an. Die Unterkante des Gehäuses des Hochvoltspeichers liegt dabei oft auf der Bodenfreiheitslinie, um einen maximalen Bauraum für den Hochvoltspeicher auszunutzen. Die der Fahrbahn zugewandte Unterseite des Hochvoltspeichers ist somit äußeren Einflüssen ausgesetzt. Dazu gehören Verschmutzungen, Steinschläge oder auch ein Aufsetzen des Fahrzeugbodens bei einer Überfahrt über einen Bordstein. Hierbei kann die Bodenstruktur beschädigt oder gar aufgerissen werden. Der Boden des Gehäuses des Hochvoltspeichers bietet erfindungsgemäß durch seine Sandwich-Struktur aus zwei miteinander verpunkteten Blechen einen ausreichenden Schutz. Dabei weist zumindest eines der beiden Bleche Verprägungen auf. Bevorzugt sind die beiden Bleche des Sandwich-Bodens umlaufend miteinander dichtend verbunden. Idealerweise sind die beiden Bleche zumindest im mittleren Bereich zueinander beabstandet und nur partiell an den Verprägungen miteinander verbunden. Dazu weist beispielsweise das untere der beiden Bleche über die Fläche verteilt Verprägungen auf, mit denen das untere Blech am oberen Blech anliegt und mit diesem punktverschweißt ist. Dieser Sandwich-Boden eines Gehäuses eines Hochvoltspeichers ist leicht, kostengünstig herstellbar, weist eine geringe Bauhöhe auf und ist außerordentlich steif.In the course of the electrification of motor vehicles, the question arises of an optimal location of the high-voltage storage. Construction spaces such as seat recesses, tunnels and also the entire underbody of the motor vehicle offer themselves here as potential installation spaces. The lower edge of the housing of the high-voltage accumulator is often located on the ground clearance line in order to exploit a maximum space for the high-voltage accumulator. The road facing the underside of the high-voltage accumulator is thus exposed to external influences. These include dirt, stone chips or even putting on the vehicle floor when crossing over a curb. In this case, the soil structure can be damaged or even torn open. The bottom of the housing of the high-voltage storage offers according to the invention by its sandwich structure of two mutually dotted sheets sufficient protection. In this case, at least one of the two sheets on stampings. Preferably, the two sheets of the sandwich bottom circumferentially connected to each other sealingly. Ideally, the two sheets are at least in the middle region spaced apart and only partially connected to the stampings. For this purpose, for example, the lower of the two sheets distributed over the surface embossments with which the lower plate rests against the upper plate and is spot welded to this. This sandwich floor of a housing of a high-voltage storage is easy, inexpensive to produce, has a low height and is extremely stiff.

Bevorzugt weist der Sandwich-Boden des Gehäuses zumindest auf der dem eigentlichen Hochvoltspeicher zugewandten Innenseite eine ebene Fläche auf. Dadurch ist der Montageaufwand bei der Speicherherstellung gering. Auch ist die ebene Fläche gut für die Kühlung und Befestigung der einzelnen Hochvoltspeicher-Einheiten geeignet.The sandwich bottom of the housing preferably has a flat surface, at least on the inner side facing the actual high-voltage accumulator. As a result, the assembly effort in memory production is low. Also, the flat surface is well suited for the cooling and mounting of the individual high-voltage storage units.

Günstigerweise wird das Gehäuse des Hochvoltspeichers ausschließlich von dem Sandwich-Boden und einem mittragenden Gehäusedeckel gebildet. Dabei kann der Gehäusedeckel zugleich die Oberseite und die Seitenwände des Gehäuses bilden. Durch die mittragende Eigenschaft des Gehäusedeckels wird ein Optimum an Steifigkeit und Festigkeit des Gehäuses bei gleichzeitigem Leichtbau erreicht. Daraus resultiert ein hoher Schutz für den Hochvoltspeicher bei gleichzeitig guten Fahrdynamikeigenschaften des Kraftfahrzeugs aufgrund des geringen Gewichts. Vorteilhafterweise ist dabei der Sandwich-Boden zum Gehäusedeckel abgedichtet. Diese Abdichtung kann durch ein einfaches Dichtsystem realisiert werden. Diese Abdichtung ermöglicht eine klare Trennung zwischen Nass- und Trockenbereich.Conveniently, the housing of the high-voltage accumulator is formed exclusively by the sandwich bottom and a carrying housing cover. In this case, the housing cover at the same time form the top and the side walls of the housing. Due to the supporting property of the housing cover, an optimum of rigidity and strength of the housing is achieved with simultaneous lightweight construction. This results in a high level of protection for the high-voltage accumulator with good driving dynamics characteristics of the motor vehicle due to the low weight. Advantageously, the sandwich bottom is sealed to the housing cover. This seal can be realized by a simple sealing system. This seal allows a clear separation between wet and dry area.

Gemäß einer weiteren vorteilhaften Ausgestaltung erstreckt sich der Hochvoltspeicher zumindest im Wesentlichen über den gesamten Unterboden des Kraftfahrzeugs. Dies ermöglicht aufgrund der großen Erstreckung in Fahrzeugquerrichtung und Fahrzeuglängsrichtung eine besonders flache Gestaltung des Hochvoltspeichers. Der Schwerpunkt des Kraftfahrzeugs befindet sich dadurch sehr tief. Dies hat große Vorteile für die Fahrdynamik des Kraftfahrzeugs.According to a further advantageous embodiment, the high-voltage accumulator extends at least substantially over the entire underbody of the motor vehicle. This allows a particularly flat design of the high-voltage accumulator due to the large extent in the vehicle transverse direction and vehicle longitudinal direction. The focus of the motor vehicle is thus very deep. This has great advantages for the driving dynamics of the motor vehicle.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, anhand dessen die Erfindung im Folgenden näher beschrieben wird. Die einige Figur zeigt in schematischer Darstellungsweise eine perspektivische Ansicht eines Halbmodells eines Gehäuses eines Hochvoltspeichers eines Kraftfahrzeugs.In the drawing, an embodiment of the invention is shown, by which the invention will be described in more detail below. The some figure shows a schematic representation of a perspective view of a half-model of a housing of a high-voltage accumulator of a motor vehicle.

Die einzige Figur zeigt ein Gehäuse 1 eines Hochvoltspeichers. Der Hochvoltspeicher ist unterhalb einer Fahrgastzelle eines Personenkraftfahrzeugs angeordnet. Er erstreckt sich in Fahrzeugquerrichtung zwischen den beiden Seitenschwellern der Karosserie des Personenkraftfahrzeugs annähernd über die gesamte Breite. In Fahrzeuglängsrichtung erstreckt er sich vom Bereich einer Stirnwand bis zum sogenannten Sitzquerträger, der im hinteren Bereich die Seitenschweller in Fahrzeugquerrichtung miteinander verbindet. In Fahrzeughöhenrichtung gesehen nach unten schließt der Hochvoltspeicher in etwa bündig mit den beiden seitlich angrenzenden Seitenschwellern ab.The single figure shows a case 1 a high-voltage memory. The high-voltage storage is arranged below a passenger compartment of a passenger vehicle. It extends in the vehicle transverse direction between the two side skirts of the body of the passenger vehicle approximately over the entire width. In the vehicle longitudinal direction, it extends from the region of an end wall to the so-called seat cross member, which connects the side skirts in the vehicle transverse direction with each other in the rear area. Seen in vehicle height direction down the high-voltage storage closes off approximately flush with the two laterally adjacent side sills.

Das in der Figur gezeigte Gehäuse 1 umgibt den eigentlichen Hochvoltspeicher schützend. Das Gehäuse 1 besteht nur aus einem Sandwich-Boden 2 und einem Gehäusedeckel 3. Der Sandwich-Boden 2 besteht aus einem oberen Blech und einem unteren Blech, die miteinander verbunden sind. Dazu weist das untere Blech im mittleren Bereich mehrere Verprägungen zum oberen Blech hin auf. Das obere Blech ist an diesen Verprägungen mit dem unteren Blech punktverschweißt. Zudem sind das obere Blech und das untere Blech umlaufend über einen gemeinsamen Flansch miteinander dichtend verbunden. Das untere Blech des Sandwich-Bodens 2 des Gehäuses 1 ist der Fahrbahn zugewandt, während auf dem oberen Blech der eigentliche Hochvoltspeicher angebracht ist. Dazu bildet das obere Blech eine einzige ebene Fläche. Dies ermöglicht eine einfache und gut zugängliche Montage der einzelnen Komponenten des Hochvoltspeichers auf dem Sandwich-Boden 2. Nach der Montage dieser Komponenten wird das Gehäuse 1 mit dem Gehäusedeckel 3 verschlossen. Der Gehäusedeckel 3 bildet die Oberseite und die Seitenwände des Gehäuses 1. Es weist an den unteren Kanten der Seitenwände umlaufend eine Dichtung auf, sodass der eigentliche Hochvoltspeicher sich im geschützten, trockenen Inneren des Gehäuses 1 befindet.The housing shown in the figure 1 surrounds the actual high-voltage memory protective. The casing 1 consists only of a sandwich bottom 2 and a housing cover 3 , The sandwich bottom 2 consists of an upper plate and a lower plate, which are connected together. For this purpose, the lower plate in the middle region on several embossings to the upper plate out. The upper sheet is spot-welded to these stampings with the lower sheet. In addition, the upper sheet and the lower sheet are peripherally sealed together by a common flange. The bottom plate of the sandwich bottom 2 of the housing 1 is the roadway facing, while mounted on the upper plate of the actual high-voltage storage. For this purpose, the upper sheet forms a single flat surface. This allows easy and accessible installation of the individual components of the high-voltage accumulator on the sandwich floor 2 , After assembling these components, the housing becomes 1 with the housing cover 3 locked. The housing cover 3 forms the top and side walls of the housing 1 , It has at the lower edges of the side walls circumferentially on a seal, so that the actual high-voltage storage in the protected, dry interior of the housing 1 located.

Der beschriebene Sandwich-Boden 2 mit den beiden miteinander verbundenen Blechen ist schnell und kostengünstig herstellbar. Zudem stellt er eine sehr robuste, steife Konstruktion eines solchen Bodens dar, der den eigentlichen Hochvoltspeicher sehr gut vor Beschädigungen schützt. Er beansprucht nur wenig Bauraum in der Fahrzeughöhenrichtung. Zusammen mit dem mittragenden Gehäusedeckel 3 weist das Gehäuse 1 eine hohe Steifigkeit und Festigkeit auf.The described sandwich bottom 2 with the two interconnected sheets is fast and inexpensive to produce. In addition, it represents a very robust, rigid construction of such a floor, which protects the actual high-voltage storage very well against damage. He claimed only little space in the vehicle height direction. Together with the supporting housing cover 3 shows the case 1 high rigidity and strength.
