Personenkraftfahrzeug mit einer Heckklappe, mit der eine hintere Karosserieöffnung eines Coupes oder eines Kraftfahrzeugs der Kombinationsbauart verschließbar ist, wobei die Heckklappe um eine an der Karosserie des Personenkraftfahrzeugs fest angebrachte, obere Achse schwenkbar gelagert ist, und wobei die Heckklappe umlaufend einen tragenden Rahmen (1) aufweist, dadurch gekennzeichnet, dass der tragende Rahmen (1) aus einem geschlossenen, einstückigen Gussrahmen besteht, der einen oberen Holm (2), einen unteren Holm (3) und einen linken und einen rechten Seitenholm (4 und 5) aufweist, wobei an der Karosserie auf der Höhe des mittleren Holms (6) beidseitig jeweils zumindest ein quaderförmiges Aufprallelement (8) befestigt ist, das bei geschlossener Heckklappe zu dieser mit einem kleinen Spalt von wenigen Millimetern beabstandet ist, wobei aufgrund der Deformation und / oder Verschiebungen bei einem Crash ein Formschluss zwischen dem Aufprallelement (8) und dem tragenden Rahmen (1) der Heckklappe in zumindest einer Richtung (L, Q) in der Ebene der Heckklappe entsteht.Passenger vehicle with a tailgate, with which a rear body opening of a coupe or a motor vehicle of the combination type can be closed, the tailgate being pivotably mounted about an upper axis fixedly attached to the body of the passenger vehicle, and the tailgate surrounding a supporting frame (1) , characterized in that the supporting frame (1) consists of a closed, one-piece cast frame, which has an upper spar (2), a lower spar (3) and a left and a right side spar (4 and 5), wherein at At least one cuboidal impact element (8) is fastened to the body at the level of the central spar (6), which is spaced apart from it with a small gap of a few millimeters when the tailgate is closed, due to the deformation and / or displacements in the event of a crash a form fit between the impact element (8) and the supporting frame (1) the tailgate arises in at least one direction (L, Q) in the plane of the tailgate.
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einer Klappe nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle with a flap according to the preamble of patent claim 1.

Aufgabe der Erfindung ist es, ein Kraftfahrzeug mit einer Klappe zu schaffen, die ein möglichst günstiges Crashverhalten aufweist.The object of the invention is to provide a motor vehicle with a flap which has the most favorable crash behavior possible.
Diese Aufgabe wird mit einem Kraftfahrzeug mit einer Klappe mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a motor vehicle with a flap with the features of patent claim 1.
Erfindungsgemäß ist eine Öffnung in der Karosserie eines Kraftfahrzeugs mit einer Klappe verschließbar, wobei an der Karosserie zumindest ein Aufprallelement befestigt ist, das bei geschlossener Klappe zu dieser beabstandet ist. Dabei kann auch eine Tür im Sinne dieser Erfindung als Klappe betrachtet werden. Bei einem Crash entsteht aufgrund der Deformation und / oder Verschiebungen ein Formschluss zwischen dem Aufprallelement und der Klappe in zumindest einer Richtung in der Ebene der Klappe. Wenn die Klappe stark gewölbt ist, bezieht sich die Ebene der Klappe auf die Ebene der Klappe nahe beim Aufprallelement. Durch den Formschluss können übermäßige Deformationen der Klappe vermieden werden. Ein Teil der in die Klappe eingeleiteten Crashenergie wird so über das zumindest eine Aufprallelement in die Karosserie abgeleitet, sodass weniger Crashenergie über weitere Deformationen der Klappe abgebaut werden muss. Typischerweise handelt es sich bei der Klappe um eine Front- oder Heckklappe. Als Klappe im Sinne der Erfindung kann aber auch jede Tür des Kraftfahrzeugs verstanden werden.According to the invention, an opening in the body of a motor vehicle can be closed with a flap, at least one impact element being fastened to the body, which is spaced apart from it when the flap is closed. A door can also be regarded as a flap in the sense of this invention. In the event of a crash, the deformation and / or displacements result in a positive fit between the impact element and the flap in at least one direction in the plane of the flap. If the flap is strongly curved, the level of the flap refers to the level of the flap near the impact element. Excessive deformation of the flap can be avoided by the positive locking. Part of the crash energy introduced into the flap is thus dissipated into the body via the at least one impact element, so that less crash energy has to be dissipated via further deformations of the flap. The flap is typically a front or rear flap. Any door of the motor vehicle can also be understood as a flap in the sense of the invention.
Bevorzugt entsteht ein Formschluss in zwei unterschiedlichen Richtungen in der Ebene der Klappe. Je besser der Formschluss ist, desto mehr Kräfte können in die Karosserie abgeleitet werden. Entsprechend geringer ist dadurch die Deformation der Klappe. Idealerweise sind die Klappe und das Aufprallelement so gestaltet, dass der Formschluss beim Crash entsteht, indem sie sich miteinander verkeilen, verblocken oder verhaken.A form fit is preferably created in two different directions in the plane of the flap. The better the form fit, the more forces can be dissipated into the body. The deformation of the flap is correspondingly less. Ideally, the flap and the impact element are designed in such a way that the positive connection is created in the event of a crash by wedging, blocking or hooking together.
Weitere vorteilhafte Ausgestaltungen sind Gegenstand von Unteransprüchen.Further advantageous embodiments are the subject of subclaims.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, anhand dessen die Erfindung im Folgenden näher beschrieben wird. Die einzelnen Figuren zeigen in schematischer Darstellungsweise:
-
1 eine perspektivische Ansicht einer Tragstruktur einer Heckklappe, -
2 einen Längsschnitt durch den linken Seitenholm der in1 gezeigten Tragstruktur und -
3 einen Höhenschnitt durch den linken Seitenholm der in1 gezeigten Tragstruktur.
-
1 a perspective view of a support structure of a tailgate, -
2 a longitudinal section through the left side member of the in1 shown support structure and -
3 a vertical section through the left side rail of the in1 shown support structure.

Bei einem Heckcrash muss die Heckklappe hohe Kräfte aufnehmen. Diese Kraftaufnahme erfolgt durch die tragende Struktur
Der Formschluss ermöglicht es, dass ein Teil der in die Heckklappe eingeleiteten Crashenergie über die Aufprallelemente
Die tragende Struktur der Heckklappe besteht aus einem Gussrahmen, der gegenüber einer tragenden Struktur aus tiefgezogenen Blechen vergleichsweise spröde ist. Daher besteht die Gefahr, dass der Gussrahmen bei einer zu starken Deformation bricht. Durch den Formschluss kann der Grad der Deformation so klein gehalten werden, dass es zu keinem Bruch des Gussrahmens kommt.The load-bearing structure of the tailgate consists of a cast frame that is comparatively brittle compared to a load-bearing structure made of deep-drawn sheet metal. There is therefore a risk that the cast frame will break if the deformation is too strong. The degree of deformation can be kept so small through the form fit that there is no breakage of the cast frame.
