Description
Die vorliegende Erfindung betrifft ein Befestigungselement für eine Batterieaufnahme einer Karosserie nach dem Oberbegriff des Anspruchs 1. Die vorliegende Erfindung betrifft darüber hinaus eine entsprechende Karosserie.The present invention relates to a fastening element for a battery holder of a body according to the preamble of claim 1. The present invention also relates to a corresponding body.
Stand der TechnikState of the art
Auf dem Gebiet der Elektromobilität bekannt sind Elemente zum Befestigen einer Traktionsbatterie oder deren Aufnahme am Fahrzeugträger der Karosserie eines Elektro- oder Hybridfahrzeugs.In the field of electromobility, elements are known for fastening a traction battery or accommodating it on the vehicle carrier of the body of an electric or hybrid vehicle.

Offenbarung der ErfindungDisclosure of Invention
Der Erfindung liegt die Aufgabe zugrunde, eine robuste Anbindung der Batterieaufnahme mit einer energieabsorbierenden Struktur zu vereinen.The object of the invention is to combine a robust connection of the battery receptacle with an energy-absorbing structure.
Die Erfindung stellt ein Befestigungselement für eine Batterieaufnahme einer Karosserie sowie eine Karosserie mit einem derartigen Element gemäß den unabhängigen Ansprüchen bereit.The invention provides a fastening element for a battery holder of a body and a body with such an element according to the independent claims.
Ein Vorzug dieser Lösung liegt in ihrer geometrischen Ausgestaltung, die eine robuste Anbindung der Batterieaufnahme über eine Schraubverbindung mit einer energieabsorbierenden Struktur vereint. Dies hat dann den positiven Effekt, dass bei einem Heckanprall eine gezielte Kinematik der Batterie gewährleistet und Aufprallenergie in Deformationsenergie bei Auflaufen dieser effektiv umgewandelt wird.An advantage of this solution lies in its geometric design, which combines a robust connection of the battery holder via a screw connection with an energy-absorbing structure. This then has the positive effect that, in the event of a rear-end collision, targeted kinematics of the battery are ensured and impact energy is effectively converted into deformation energy when it hits the ground.
Der Erfindung liegt hierbei die Erkenntnis zugrunde, dass eine HV-Batterie „weich“ an Rohbau angebunden werden muss. Die Anbindung muss dabei sichergestellt sein, um einschlägigen Gesetzesanforderungen zu genügen, wie sie beispielsweise in §571.305 des US-amerikanischen Federal Motor Vehicle Safety Standards (FMVSS) Nr. 305 normiert sind.The invention is based on the knowledge that an HV battery must be connected “softly” to the shell. The connection must be ensured in order to meet relevant legal requirements, such as those standardized in Section 571.305 of the US Federal Motor Vehicle Safety Standard (FMVSS) No. 305.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So kann das Befestigungselement derart ausgelegt sein, dass das Deformationselement einer entlang der Wankachse der Karosserie wirkenden Deformationskraft bis zu einer vorgegebenen Belastungsgrenze widersteht und jenseits der Belastungsgrenze kollabiert. Durch diesen kontrollierten Vorgang wird die Belastung auf die Batterie nach oben begrenzt.Further advantageous refinements of the invention are specified in the dependent patent claims. The fastening element can be designed in such a way that the deformation element withstands a deformation force acting along the roll axis of the body up to a predetermined load limit and collapses beyond the load limit. This controlled process limits the load on the battery.
