Abstract
Die Erfindung stellt ein Befestigungselement (10) für eine Batterieaufnahme einer Karosserie mit den folgenden Merkmalen bereit: das Befestigungselement (10) umfasst ein in einen Querträger der Karosserie einlegbares Deformationselement (14) zum Aufnehmen einer entlang einer Wankachse der Karosserie wirkenden Deformationskraft; das Befestigungselement (10) umfasst eine an das Deformationselement (14) angeformte Verbindungsfläche (19); und die Verbindungsfläche (19) wird von einer senkrechten Bohrung (15) zum Aufnehmen einer die Batterieaufnahme am Querträger befestigenden Schraube durchzogen. Die Erfindung stellt ferner eine entsprechende Karosserie bereit.The invention provides a fastening element (10) for a battery receptacle of a body with the following features: the fastening element (10) comprises a deformation element (14) which can be inserted into a cross member of the body to absorb a deformation force acting along a roll axis of the body; the fastening element (10) comprises a connection surface (19) integrally formed on the deformation element (14); and the connecting surface (19) is penetrated by a vertical bore (15) for receiving a screw securing the battery holder to the cross member. The invention further provides a corresponding body.
Description
Die vorliegende Erfindung betrifft ein Befestigungselement für eine Batterieaufnahme einer Karosserie. Die vorliegende Erfindung betrifft darüber hinaus eine entsprechende Karosserie. The present invention relates to a fastening element for a battery receptacle of a body. The present invention also relates to a corresponding body.
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 are known elements for securing a traction battery or its inclusion on the vehicle carrier of the body of an electric or hybrid vehicle.

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 fastener for a battery receptacle of a body as well as 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. One advantage of this solution lies in its geometric configuration, which combines a robust connection of the battery receptacle via a screw connection with an energy-absorbing structure. This then has the positive effect that in a Heckanprall a targeted kinematics of the battery ensures and impact energy is effectively converted into deformation energy at emergence of this.
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 finding that a high-voltage battery must be connected to the bodyshell "softly." The connection must be ensured in order to comply with relevant legal requirements, as described, for example, in §571.305 of the US Federal Motor Vehicle Safety Standard (FMVSS) No. 305 are normalized.
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 embodiments of the invention are specified in the dependent claims. Thus, the fastening element can be designed such that the deformation element of a deformation force acting along the roll axis of the body resists to a predetermined load limit and collapses beyond the load limit. This controlled process limits the load on the battery.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben. An embodiment of the invention is illustrated in the drawings and will be described in more detail below.
