Abstract
Die Erfindung betrifft eine Schutzvorrichtung (S) für einen in einem Bodenbereich eines Fahrzeuges (3) angeordneten Energiespeicher (1). Erfindungsgemäß sind bzw. ist zumindest ein Airbag (4) und/oder zumindest ein Druckbehälter mit einem aushärtbaren Schaum vorgesehen, wobei der zumindest eine Airbag (4) in seiner Wirkstellung und/oder der aus dem zumindest einen Druckbehälter freigesetzte Schaum zwischen dem Energiespeicher (1) und einer Raumlenker-Hinterachse (2) des Fahrzeuges (3) angeordnet sind bzw. ist.The invention relates to a protective device (S) for an energy store (1) arranged in a floor area of a vehicle (3). According to the invention, at least one airbag (4) and / or at least one pressure vessel with a curable foam is provided, wherein the at least one airbag (4) in its operative position and / or the foam released from the at least one pressure vessel between the energy store (1 ) and a multi-link rear axle (2) of the vehicle (3) are arranged or is.
Description
Die Erfindung betrifft eine Schutzvorrichtung für einen in einem Bodenbereich eines Fahrzeuges angeordneten Energiespeicher.The invention relates to a protective device for a arranged in a bottom portion of a vehicle energy storage.
Im Allgemeinen ist eine Schutzvorrichtung für einen im Bodenbereich eines Fahrzeuges angeordneten Energiespeicher bekannt, wobei die Schutzvorrichtung aus Verstärkungsteilen eines Behälters des Energiespeichers gebildet sein kann.In general, a protective device for an energy store arranged in the floor area of a vehicle is known, wherein the protective device can be formed from reinforcing parts of a container of the energy store.
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Schutzvorrichtung für einen Energiespeicher eines Fahrzeuges anzugeben.The invention has for its object to provide a comparison with the prior art improved protection device for an energy storage of a vehicle.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Schutzvorrichtung für einen in einem Bodenbereich eines Fahrzeuges angeordneten Energiespeicher umfasst erfindungsgemäß zumindest einen Airbag und/oder zumindest einen Druckbehälter mit einem aushärtbaren Schaum, wobei der zumindest eine Airbag in seiner Wirkstellung und/oder der aus dem zumindest einen Druckbehälter freigesetzte Schaum zwischen dem Energiespeicher und einer Raumlenker-Hinterachse des Fahrzeuges angeordnet sind bzw. ist. Bei der Raumlenker-Hinterachse handelt es sich zweckmäßigerweise um eine Ausführungsform einer Mehrlenkerhinterachse.A protective device for an energy store arranged in a floor region of a vehicle comprises according to the invention at least one airbag and / or at least one pressure vessel with a curable foam, wherein the at least one airbag is in its active position and / or the foam released between the energy store and the at least one pressure vessel a multi-link rear axle of the vehicle are arranged or is. The multi-link rear axle is expediently an embodiment of a multi-link rear axle.
Mittels des Airbags in seiner Wirkstellung und/oder mittels des freigesetzten vergleichsweise schnell aushärtbaren Schaumes ist das Risiko einer Beschädigung des Energiespeichers des Fahrzeuges, insbesondere eines Kraftstofftanks, aufgrund kollisionsbedingt deformierter Bauteile der Raumlenker-Hinterachse wesentlich verringert.By means of the airbag in its operative position and / or by means of the liberated comparatively rapidly curable foam, the risk of damaging the energy accumulator of the vehicle, in particular of a fuel tank, due to collision-induced deformed components of the multi-link rear axle is substantially reduced.
Dabei dient der zumindest eine Airbag als Barriere für die deformierten Bauteile der Raumlenker-Hinterachse. Bei Verwendung des vergleichsweise schnell aushärtbaren Schaumes können durch diesen Schaum Splitterkörper abgebremst und/oder aufgefangen werden, so dass diese nicht in den Energiespeicher eindringen können.In this case, the at least one airbag serves as a barrier for the deformed components of the multi-link rear axle. When using the relatively rapidly curable foam fragment body can be slowed down and / or collected by this foam, so that they can not penetrate into the energy storage.
Mittels der Schutzvorrichtung kann eine Beschädigung des Energiespeichers zumindest verringert werden, so dass das Risiko eines Austretens, beispielsweise von Kraftstoff, wesentlich verringert ist und dadurch wiederum eine Brandgefahr verringert werden kann.By means of the protection device damage to the energy storage device can at least be reduced, so that the risk of leakage, for example of fuel, is substantially reduced, and in turn a risk of fire can be reduced.
