Description
Die Erfindung betrifft eine Anordnung einer Frontklappe an einem Fahrzeug gemäß des Oberbegriffs des Patentanspruchs 1.The The invention relates to an arrangement of a front flap on a vehicle according to the preamble of claim 1
Um bei einer Kollision eines Fußgängers oder Radfahrers mit einem Kraftfahrzeug das Ausmaß von Verletzungen, insbesondere im Brust- und Kopfbereich, zu minimieren, ist es allgemein bekannt, einen relativ großen Mindestabstand zwischen einer Frontklappe und einer steifen Unterstruktur des Fahrzeugs (Motor, Federbeinaufnahmen, etc.) vorzusehen, sodass ein ausreichender Deformationsweg der Frontklappe zur Verfügung steht, um den Aufprall des Fußgängers oder Radfahrers auf ein verträgliches Maß zu verzögern. Kritisch bleibt allerdings der Bereich der Frontklappe nahe bei Scharnieren, mit denen die Frontklappe an die Karosserie angelenkt ist, da die Frontklappe in diesem Bereich nicht ausreichend deformierbar ist.Around in a collision of a pedestrian or Cyclist with a motor vehicle the extent of injury, in particular in the chest and head area, it is well known a relatively large one Minimum distance between a front flap and a stiff substructure the vehicle (engine, strut mountings, etc.) so that a sufficient deformation path of the front flap is available to the impact of the pedestrian or Cyclist on a tolerable Measure too delay. However, the area of the front flap remains close to critical Hinges with which the front flap is hinged to the body, because the front flap is not sufficiently deformable in this area is.
Zur Vermeidung dieses kritischen Bereichs ist es aus der JP 2000-108842 A bekannt, zwischen dem Scharnier und der Frontklappe und zwischen dem Scharnier und der Karosserie jeweils ein energieabsorbierendes Element aus einem elastischen Material anzubringen.to Avoiding this critical area is known from JP 2000-108842 A known between the hinge and the front flap and between the Hinge and the body each have an energy-absorbing element made of an elastic material.
Aufgabe der Erfindung ist es, eine Anordnung einer Frontklappe an einem Fahrzeug zu schaffen, die einen aufprallenden Fußgänger oder Radfahrer so gut wie möglich vor Verletzungen schützt.task The invention is an arrangement of a front door on a Vehicle to create a bouncing pedestrian or cyclist so well as possible protects against injury.
Diese Aufgabe wird durch eine Anordnung einer Frontklappe an einem Fahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is by an arrangement of a front door on a vehicle solved with the features of claim 1.
Erfindungsgemäß ist eine Frontklappe mit zumindest einer Scharniereinrichtung mit der Karosserie eines Fahrzeugs verbunden, wobei zwischen der Scharniereinrichtung und der Karosserie zumindest ein Deformationselement zum Schutz eines aufprallenden Fußgängers oder Radfahrers angeordnet ist. Die Scharniereinrichtung weist zur Karosserie eine Führung auf, die eine Verlagerung der Scharniereinrichtung relativ zur Karosserie in Fahrtrichtung gesehen nach hinten bei einem Frontalaufprall des Fahrzeugs verhindert. Insbesondere bei höheren Fahrzeuggeschwindigkeiten entstehen bei einem Frontalaufprall des Fahrzeugs in Fahrtrichtung hohe Kräfte, die auf die Frontklappe wirken. Das Deformationselement unterhalb der Scharniereinrichtung kann sich durch diese Kräfte in x-Richtung möglicherweise so verformen, dass sich die Scharniereinrichtung und somit die Frontklappe unerwünschterweise nach hinten verlagert. Im Extremfall könnte die Frontklappe dadurch in eine Windschutzscheibe des Fahrzeugs eindringen. Aufgrund der erfindungsgemäßen Führung zwischen Scharniereinrichtung und Karosserie ist keine Verlagerung der Scharniereinrichtung und damit der mit der Scharniereinrichtung verbundenen Frontklappe in Fahrtrichtung nach hinten mehr möglich.According to the invention is a Front flap with at least one hinge device with the bodywork connected to a vehicle, wherein between the hinge means and the body at least one deformation element for protection of a bouncing pedestrian or Cyclist is arranged. The hinge means has a body to the guide on, which is a displacement of the hinge relative to the body seen in the direction of travel to the rear in a frontal collision of the vehicle prevented. Especially at higher vehicle speeds occur in a frontal collision of the vehicle in the direction of travel high powers, which act on the front flap. The deformation element below the hinge device can move through these forces in the x direction possibly so deform that the hinge means and thus the front flap undesirably after shifted behind. In extreme cases, the front flap could thereby penetrate into a windshield of the vehicle. Due to the guide according to the invention between Hinge and body is not a displacement of the hinge and so that the front flap connected to the hinge device in Direction of travel to the rear more possible.
Günstigerweise ist zur Führung an der Scharniereinrichtung eine Führungsplatte mit zumindest einem Langloch angebracht, durch das zumindest ein mit der Karosserie verbundener Bolzen ragt. Dies ist eine der einfachsten Möglichkeiten, eine Führung zu realisieren, die zudem besonders wenig Bauraum benötigt. Im Idealfall kann die Führungsplatte einteilig mit einem Bauteil der Scharniereinrichtung ausgeführt sein, sodass keine zusätzlichen Bauteile bis auf den Bolzen erforderlich sind. Die Längserstreckung des Langlochs verläuft dabei vorteilhafterweise im wesentlichen senkrecht zur Fahrbahnebene, also in z-Richtung. Natürlich kann auch umgekehrt an der Scharniereinrichtung zumindest ein Bolzen angebracht sein, der in einem Langloch in einem fest mit der Karosserie verbundenen Bauteil geführt ist.conveniently, is for leadership on the hinge means a guide plate with at least attached to a slot through which at least one with the body connected bolt protrudes. This is one of the easiest ways a guide to realize, which also requires very little space. in the Ideally, the guide plate can be one-piece be executed with a component of the hinge device, so no extra Components are required except for the bolt. The longitudinal extension the long hole runs thereby advantageously substantially perpendicular to the road surface, ie in the z direction. Naturally can also be reversed on the hinge at least one bolt be attached in a slot in a fixed to the bodywork led connected component is.
Idealerweise ist auf dem Deformationselement nicht nur die Scharniereinrichtung angebracht, sondern zugleich auch ein Kotflügel. Das Deformationselement stellt so sowohl einen Schutz für Fußgänger und Radfahrer dar, die auf der Frontklappe aufprallen, als auch für diejenigen, die auf dem Kotflügel aufprallen, da der Kotflügel über das Deformationselement ebenfalls nachgeben kann. Zur Befestigung des Kotflügels sind keine weiteren Zusatzbauteile mehr erforderlich. Da sowohl die Frontklappe über die Scharniereinrichtung als auch der Kotflügel am Deformationselement befestigt sind, lassen sich besonders schmale Fugenmaße realisieren, und der Aufwand zum Einstellen der Frontklappe relativ zum Kotflügel ist gering.Ideally is not only the hinge on the deformation element attached, but at the same time a fender. The deformation element thus provides both a protection for Pedestrians and Cyclists bouncing on the front door, as well as those the on the fender bounce, as the fender over the Deformation also yield. For attachment of the fender No additional components are required. Because both the front flap over the hinge device and the fender on the deformation element are fixed, particularly narrow joint dimensions can be realized and the effort to adjust the front door relative to the fender is low.
Weitere vorteilhafte Ausgestaltungen sind Gegenstand von Unteransprüchen.Further advantageous embodiments are the subject of dependent claims.
