Abstract
Description
Die Erfindung betrifft eine Tragstruktur für einen hinteren Stoßfänger eines Personenkraftwagens der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a support structure for a rear Bumper of a passenger car which in the preamble of the patent claim 1 specified type.
Eine
solche Tragstruktur ist beispielsweise bereits aus der
Insbesondere bei so genannten SUV-Fahrzeugen ist jedoch ein relativ großer Wirküberhang am hinteren Stoßfänger vorhanden und somit beispielsweise die Ladekante unter der Heckklappe des Personenkraftwagens sehr breit ausgebildet. Hierdurch besteht beispielsweise die Möglichkeit, dass sich eine Person auf die Ladekante des Stoßfängers stellt oder dass diese Kante mit schwerem Ladegut belastet wird.Especially However, in so-called SUV vehicles is a relatively large Effective overhang at the rear bumper available and thus, for example, the loading sill under the tailgate of the Passenger car very wide trained. As a result, for example the possibility of getting a person on the sill the bumper or that edge with heavy cargo is loaded.
Aufgabe der vorliegenden Erfindung ist es daher, eine Tragstruktur der eingangs genannten Art zu schaffen, welche einerseits den Belastungen bei Beaufschlagung der Ladekante mit einem höheren Gewicht standhält und andererseits bei einer unfallbedingten Kraftbeaufschlagung den dahinter liegenden Rohbau des Personenkraftwagens nicht beschädigt.task The present invention is therefore a support structure of the above to create said type, which on the one hand the loads when loading the sill withstands a higher weight and on the other hand, in an accidental Kraftbeaufschlagung the Behind it lying shell of the passenger car not damaged.
Diese Aufgabe wird erfindungsgemäß durch eine Tragstruktur mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen angegeben.These The object is achieved by a support structure solved with the features of claim 1. advantageous Embodiments with appropriate and non-trivial Further developments of the invention are specified in the other claims.
Um eine Tragstruktur zu schaffen, welche einerseits den Belastungen bei Beaufschlagung der Ladekante mit einem höheren Gewicht standhält und andererseits bei einer unfallbedingten Kraftbeaufschlagung den dahinter liegenden Rohbau des Personenkraftwagens nicht beschädigt, ist es erfindungsgemäß vorgesehen, dass die Strukturbereiche der Tragstruktur mit Abstützbereichen versehen sind, mittels welchen die Ladekante des hinteren Stoßfängers in Fahrzeughochrichtung abstützbar ist.Around to create a supporting structure, which on the one hand the loads when loading the sill with a higher weight withstand and on the other hand in an accidental Kraftbeaufschlagung the underlying shell of the passenger car is not damaged, It is inventively provided that the structural areas of the Support structure are provided with support areas, by means which the loading edge of the rear bumper can be supported in the vehicle vertical direction.
Mit anderen Worten ist durch die bis zumindest annähernd auf Höhe der Ladekante ragenden Strukturbereiche sichergestellt, dass die Tragstruktur auch in vertikaler Richtung große Kräfte aufnehmen kann. So ist es beispielsweise bei SUV-Fahrzeugen, welche einen relativ großen Wirküberhang und eine dementsprechend breite Ladekante haben, auf einfache Weise sicherzustellen, dass der Stoßfänger in Vertikalrichtung entsprechend steif ausgebildet ist, um beispielsweise durch eine auf der Ladekante stehende Person oder durch auf der Ladekante abgestelltes Ladegut beaufschlagt werden zu können.With other words is through to at least approximately Height of the sill protruding structural areas ensured that the support structure also large in the vertical direction Can absorb forces. This is the case with SUV vehicles, for example a relatively large effective overhang and accordingly wide sill, to easily ensure that the bumper in the vertical direction accordingly is stiff, for example, by a on the sill standing person or by on the sill parked cargo to be able to be charged.
Um dennoch zu vermeiden, dass bei einer unfallbedingten Kraftbeaufschlagung des Stoßfängers beispielsweise infolge eines Heckaufpralls der Rohbau des Personenkraftwagens durch die auftreffende Tragstruktur im erheblichen Umfang beschädigt wird, ist der insgesamt etwa ziehharmonikaartigen Verlauf der Tragstruktur bzw. der Strukturbereiche vorgesehen. Somit ist sichergestellt, dass die Tragstruktur in Fahrzeuglängsrichtung entsprechend nachgiebig ausgebildet ist, so dass bei einer unfallbedingten Kraftbeaufschlagung bzw. Verschiebung der dahinter liegende Rohbau des Personenkraftwagens nicht beschädigt wird.Around nevertheless to avoid that in the event of an accidental application of force the bumper, for example, due to a rear impact the shell of the passenger car by the impinging support structure is damaged to a considerable extent, is the total about accordion-like course of the support structure or the structural areas intended. This ensures that the support structure in the vehicle longitudinal direction is designed accordingly yielding, so that in an accident Applying force or displacement of the underlying shell of the passenger car is not damaged.
Die ziehharmonikaartige Ausgestaltung der Tragstruktur lässt sich beispielsweise dadurch realisieren, dass alternierend nach außen hin abstehende Strukturbereiche und Aussparungen vorgesehen sind, wobei im Bereich der Aussparungen jeweilige Stegwände vorgesehen sind. Um dabei die erforderliche Nachgiebigkeit zu erreichen, sind beispielsweise in in Fahrzeughochrichtung verlaufende Wände der Strukturbereiche und in die Stegwände jeweilige Öffnungen eingebracht.The accordion-like design of the support structure leaves For example, realize that alternately after Outside protruding structural areas and recesses are provided, wherein in the region of the recesses respective web walls are provided. In order to achieve the required flexibility, For example, in running in the vehicle vertical direction walls of Structural areas and in the web walls respective openings brought in.
Eine weiter vorteilhafte Ausführungsform der Tragstruktur sieht vor, dass die Strukturbereiche über die gesamte Höhe des zugeordneten Bereichs der Tragstruktur verlaufen. Dies hat den Vorteil, dass insbesondere in Fahrzeughochrichtung hohe Kräfte durch den Stoßfänger aufgenommen werden können.A sees further advantageous embodiment of the support structure before that the structural areas over the entire height of the associated area of the support structure. This has the Advantage that in particular in the vehicle vertical direction high forces the bumper can be recorded.
Als zudem vorteilhaft hat es sich gezeigt, wenn die jeweiligen Vorderseiten der Strukturbereiche von zugehörigen Ausnehmungen durchsetzt sind, welche somit im Wesentlichen quer zu den sich in Fahrzeughochrichtung erstreckenden Ausnehmungen verlaufen. Durch diese weiteren Ausnehmungen an den Vorderseiten der Strukturbereiche kann die Nachgiebigkeit der jeweiligen Strukturbereiche entsprechend eingestellt bzw. gesteuert werden.When In addition, it has been shown to be advantageous if the respective front sides the structural areas are penetrated by associated recesses, which thus substantially transversely to the vehicle in the vertical direction extend extending recesses. Through these further recesses on the front sides of the structural areas, the compliance can the respective structural areas set or controlled accordingly become.
