Description

Die Erfindung betrifft eine Vorrichtung zur Aufnahme einer Batterie mit einer Haltevorrichtung, welche in oder an einem Fahrzeug, insbesondere Elektro- und/oder Hybridfahrzeug, anordenbar ist.The invention relates to a device for receiving a battery with a holding device, which can be arranged in or on a vehicle, in particular electric and / or hybrid vehicle.

Vorrichtungen zur Aufnahme einer Batterie, die in einem Fahrzeug, insbesondere Elektro- und/oder Hybridfahrzeug, anordenbar sind, sind bereits bekannt. Die Batterie ist üblicherweise in einem Gehäuse angeordnet, welches über starr ausgebildete Befestigungselemente mit dem Fahrzeug verbunden wird.Devices for receiving a battery, which can be arranged in a vehicle, in particular electric and / or hybrid vehicle, are already known. The battery is usually arranged in a housing, which is connected via rigidly formed fastening elements with the vehicle.

Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zur Aufnahme einer Batterie anzugeben, mittels welcher eine Reduzierung von Insassenbelastungen während einer Kollision, insbesondere Frontalkollision, des Fahrzeugs mit einem Objekt möglich ist.The invention has for its object to provide a comparison with the prior art improved device for receiving a battery, by means of which a reduction of occupant loads during a collision, in particular frontal collision, the vehicle with an object is possible.

Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved by a device having 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 Vorrichtung zur Aufnahme mindestens einer Batterie ist mittels einer Haltevorrichtung in oder an einem Fahrzeug, insbesondere Elektro- und/oder Hybridfahrzeug, anordenbar. Erfindungsgemäß ist vorgesehen, dass die Haltevorrichtung eine Anzahl von deformierbaren Befestigungselementen umfasst.A device for receiving at least one battery can be arranged by means of a holding device in or on a vehicle, in particular electric and / or hybrid vehicle. According to the invention, it is provided that the holding device comprises a number of deformable fastening elements.

Die aus dieser Vorrichtung resultierende flexible Anbindung der Batterie an das Fahrzeug verbessert eine Verzögerungs- und Beschleunigungscharakteristik des Fahrzeugs, insbesondere während einer Frontalkollision des Fahrzeugs mit einem Objekt, da ein Masseneinfluss der Batterie während der Frontalkollision zeitlich verschoben wird. Infolgedessen wird eine kinetische Energie der Batterie, die diese aufgrund ihrer Trägheitseigenschaften während einer Frontalkollision erfährt, zumindest teilweise absorbiert. Dadurch kann das Risiko von mechanischen Beschädigungen der Batterie verringert werden, da eine Belastung auf die Batterie während der Frontalkollision gering gehalten wird.The flexible connection of the battery to the vehicle resulting from this device improves a deceleration and acceleration characteristic of the vehicle, in particular during a frontal collision of the vehicle with an object, since a mass influence of the battery is shifted in time during the frontal collision. As a result, a kinetic energy of the battery that it experiences due to its inertial properties during a frontal collision is at least partially absorbed. This can reduce the risk of mechanical damage to the battery as it minimizes stress on the battery during head-on collision.

Darüber hinaus erlaubt die Vorrichtung in vorteilhafter Weise eine Reduzierung von Insassenbelastungen während der Frontalkollision, da die auf die Insassen einwirkenden Massenkräfte des Fahrzeugs und der Batterie zeitlich verschoben sind.In addition, the device advantageously allows a reduction of occupant loads during the frontal collision, as the force acting on the occupants inertial forces of the vehicle and the battery are shifted in time.

Die Haltevorrichtung 2.1 umfasst eine Anzahl von Befestigungselementen 2.1.1, welche jeweils an den Seitenflächen 2.2 der Vorrichtung 2 angeordnet sind. Im vorliegenden Ausführungsbeispiel sind zwei Befestigungselemente 2.1.1 dargestellt, welche an den in y-Richtung verlaufenden Seitenflächen 2.2 der Vorrichtung 2 angeordnet sind.The holding device 2.1 includes a number of fasteners 2.1.1 , each on the side surfaces 2.2 the device 2 are arranged. In the present embodiment, two fasteners 2.1.1 shown, which at the side surfaces extending in the y-direction 2.2 the device 2 are arranged.

Die Befestigungselemente 2.1.1 sind jeweils deformierbar ausgebildet und stellen schwingungsdämpfende Feder- und/oder Dämpfungselemente dar. Vorzugsweise sind bei Verwendung von Dämpfungselementen die Dämpfungseigenschaften der Befestigungselemente 2.1.1 einstellbar. Denkbär wäre z. B. ein Strukturschaum, dessen Porenstruktur in Bezug auf die Porengroße einstellbar ist.The fasteners 2.1.1 are each formed deformable and are vibration-damping spring and / or damping elements. Preferably, when using damping elements, the damping properties of the fasteners 2.1.1 adjustable. Denkbär would be z. B. a structural foam whose pore structure is adjustable with respect to the pore size.

Weiterhin sind als Befestigungselemente 2.1.1 beispielsweise Metall- oder Kunststofffedern oder Elastomer-Elemente mit reversiblen Deformationseigenschaften oder auch Befestigungselemente 2.1.1 mit einer Sollbruchstelle und damit irreversiblen Deformationseigenschaften einsetzbar.Furthermore, as fasteners 2.1.1 For example, metal or plastic springs or elastomer elements with reversible deformation properties or fasteners 2.1.1 can be used with a predetermined breaking point and thus irreversible deformation properties.

B. ein Längsträger und/oder Querträger am Fahrzeugboden, sowie mit der Vorrichtung 2 verschraubt.The fasteners 2.1.1 are both with the vehicle 1 as well as with the device 2 each positively and / or positively and / or materially connected. For example, the fasteners 2.1.1 on their front sides in each case with the vehicle 1 , in particular with a vehicle body element, for. B. a side member and / or cross member on the vehicle floor, as well as with the device 2 screwed.

Durch eine derartig deformierbare Ausbildung der Befestigungselemente 2.1.1 ist im Sinne eines Feder-Dämpfer-Masse-Systems eine Übertragung von Schwingungen vom Fahrzeug 1 auf die Batterie 3 oder umgekehrt vorteilhaft beeinflussbar.By such a deformable design of the fasteners 2.1.1 is in the sense of a spring-damper mass system, a transmission of vibrations from the vehicle 1 on the battery 3 or vice versa advantageously influenced.

Insbesondere während einer Frontalkollision des Fahrzeugs 1 mit einem Objekt wird ein Masseneinfluss der Batterie auf das Fahrzeug 1 und damit auf Fahrzeuginsassen zeitlich verschoben. Damit ist in vorteilhafter Weise eine Reduzierung von Insassenbelastungen während der Frontalkollision möglich.In particular, during a frontal collision of the vehicle 1 with an object becomes a mass influence of the battery on the vehicle 1 and thus on vehicle occupants postponed. This is advantageously a reduction of occupant loads during the frontal collision possible.

Die kinetische Energie der Batterie 3, die diese aufgrund ihrer Trägheitseigenschaften während der Frontalkollision erfährt, wird durch die deformierbaren Befestigungselemente 2.1.1 zumindest teilweise absorbiert, wodurch das Risiko von mechanischen Beschädigungen der Batterie 3 verringert werden kann. Damit ist eine positive Beeinflussung einer Verzögerungskennlinie der bei einer Frontalkollision wirkenden Massen positiv beeinflussbar.The kinetic energy of the battery 3 which it experiences due to its inertial properties during frontal collision is due to the deformable fasteners 2.1.1 at least partially absorbed, reducing the risk of mechanical damage to the battery 3 can be reduced. In this way, a positive influence on a deceleration characteristic of the masses acting in a frontal collision can be positively influenced.
