Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einer Karosserie mit einer Bodenstruktur nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle having a body with a floor structure according to the preamble of patent claim 1.
Im Kraftfahrzeugbau ist es allgemein bekannt, die Bodenstruktur einer Fahrzeugkarosserie im Bereich der Fahrgastzelle in Fahrzeuglängsrichtung durch Seitenschweller und einen Mitteltunnel zu versteifen. In Fahrzeugquerrichtung erfolgt die erforderliche Versteifung meist durch ein sogenanntes Fersenblech, das sich unterhalb einer hinteren Sitzreihe zwischen den beiden Seitenschwellern in Fahrzeugquerrichtung erstreckt. Im vorderen Bereich erfolgt die Versteifung in Fahrzeugquerrichtung durch eine Stirnwand, die zugleich die vordere Begrenzung der Fahrgastzelle bildet.In the automotive industry, it is generally known to stiffen the floor structure of a vehicle body in the passenger compartment in the vehicle longitudinal direction by side skirts and a center tunnel. In the vehicle transverse direction, the required stiffening is usually done by a so-called heel plate, which extends below a rear row of seats between the two side sills in the vehicle transverse direction. In the front area, the stiffening takes place in the vehicle transverse direction through an end wall, which also forms the front boundary of the passenger compartment.
Bei Kraftfahrzeugen mit anderen Antriebskonzepten als einer konventionellen Brennkraftmaschine stellt sich im Fahrzeugbau die Frage, wo die erforderlichen Energiespeicher untergebracht werden können. So ist es beispielsweise aus der
Aufgabe der Erfindung ist es, ein Kraftfahrzeug mit einer Karosserie mit einer Bodenstruktur zu schaffen, an der ein Energiespeicher angebracht ist, wobei das Kraftfahrzeug eine hohe Gesamtsteifigkeit aufweist.The object of the invention is to provide a motor vehicle with a body with a floor structure, to which an energy storage device is mounted, wherein the motor vehicle has a high overall rigidity.
Diese Aufgabe wird mit einem Kraftfahrzeug mit einer Karosserie mit einer Bodenstruktur mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a motor vehicle having a body with a floor structure having the features of patent claim 1.
Erfindungsgemäß weist ein Kraftfahrzeug eine Karosserie mit einer Bodenstruktur auf, an deren Unterseite im Bereich einer Fahrgastzelle ein Energiespeicher in Fahrzeugquerrichtung gesehen mittig angebracht ist. Ein solcher Energiespeicher kann beispielsweise ein Batteriemodul bzw. ein Hochvoltspeicher sein. Die Bodenstruktur der Karosserie ist beidseitig jeweils durch einen sich in Fahrzeuglängsrichtung erstreckenden Seitenschweller begrenzt.According to the invention, a motor vehicle has a body with a floor structure, on the underside of which in the region of a passenger compartment an energy store in the vehicle transverse direction is mounted centrally. Such an energy store may be, for example, a battery module or a high-voltage storage. The floor structure of the body is bounded on both sides by a side sill extending in the vehicle longitudinal direction.
Es hat sich als vorteilhaft herausgestellt, den Energiespeicher mittig unter der Bodenstruktur im Bereich der Fahrgastzelle anzuordnen. Dann stehen der Vorderwagen und der Hinterwagen des Kraftfahrzeugs als Knauschzone für Front- bzw. Heckcrashs zur Verfügung, sodass die Fahrgastzelle mit dem darunter angeordneten Energiespeicher geschützt ist, sofern die Fahrgastzelle eine ausreichende Steifigkeit aufweist. Bei Seitencrashs wird ein Großteil der Energie über die Seitenschweller aufgenommen. Der Energiespeicher erstreckt sich dabei seitlich nicht bis zu den Seitenschwellern. Damit ist bei der erfindungsgemäßen Anordnung der Energiespeicher auch bei einem Seitencrash gut geschützt.It has proven to be advantageous to arrange the energy store centrally under the floor structure in the area of the passenger compartment. Then the front end and the rear end of the motor vehicle are available as an interference zone for front or rear crashes, so that the passenger compartment is protected with the energy store arranged underneath, provided that the passenger compartment has sufficient rigidity. In side crashes, much of the energy is absorbed through the side skirts. The energy storage does not extend laterally to the side sills. Thus, in the arrangement according to the invention, the energy storage is well protected even in a side crash.
Der Energiespeicher belegt viel Bauraum im Bodenbereich des Kraftfahrzeugs, der bei konventionellen Karosserien von aussteifenden Karosseriestrukturen beansprucht wird. Die erfindungsgemäße Karosserie soll aber trotz der Anordnung eines Energiespeichers an der Unterseite der Bodenstruktur eine hohe Steifigkeit aufweisen, damit die Fahrgastzelle bei einem Crash möglichst geringfügig beschädigt wird. Dazu ist der Energiespeicher als tragendes Karosseriebauteil ausgebildet. Bevorzugt weist der Energiespeicher ein tragendes Gehäuse auf. Vorteilhafterweise umfasst das Gehäuse dazu tragende Seitenwände, einen tragenden Boden und einen tragenden Deckel. Zusätzlich kann in dem Gehäuse zur weiteren Versteifung in Fahrzeugquerrichtung gesehen im mittleren Bereich des Gehäuses ein Längssteg angeordnet sein, der sich in Fahrzeuglängsrichtung zwischen der vorderen und der hinteren Seitenwand erstreckt. Dieser Längssteg kann sich zudem in Fahrzeughöhenrichtung gesehen über die gesamte Höhe des Gehäuses erstrecken und den Boden mit dem Deckel verbinden. Auch kann bevorzugt in dem Gehäuse zur Versteifung zumindest ein Quersteg angeordnet sein, der sich in Fahrzeugquerrichtung zwischen den beiden seitlichen Seitenwänden erstreckt.The energy storage occupies a lot of space in the floor area of the motor vehicle, which is claimed in conventional bodies of stiffening body structures. The body according to the invention should, however, despite the arrangement of an energy storage at the bottom of the soil structure have a high rigidity, so that the passenger compartment is damaged as slightly as possible in a crash. For this purpose, the energy storage is designed as a supporting body component. The energy store preferably has a load-bearing housing. Advantageously, the housing comprises supporting side walls, a load-bearing floor and a load-bearing lid. In addition, seen in the housing for further stiffening in the vehicle transverse direction in the central region of the housing may be arranged a longitudinal web extending in the vehicle longitudinal direction between the front and the rear side wall. This longitudinal web can also extend in the vehicle height direction over the entire height of the housing and connect the floor with the lid. Also, at least one transverse web can preferably be arranged in the housing for stiffening, which extends in the vehicle transverse direction between the two lateral side walls.
Weitere vorteilhafte Ausgestaltungen sind Gegenstand von Unteransprüchen.Further advantageous embodiments are the subject of dependent claims.
