Abstract
Description
Die Erfindung betrifft einen Vorderbau für ein Kraftfahrzeug mit einer an einem Karosserieteil angelenkten Fronthaube, mit einem in seiner Höhe einstellbaren Puffer, wobei der Puffer eine vorgesehene, bei einem Aufprall auf die Fronthaube nachgebende Festigkeit aufweist.The The invention relates to a front structure for a motor vehicle with a on a body part hinged front hood, with a in his Height adjustable Buffer, wherein the buffer provided, in an impact the bonnet has yielding strength.
Solche Vorderbauten werden bei heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Bei der bekannten Einrichtungen kollabiert der Puffer bei einer vorgesehenen Belastung und soll ein Absenken der Haube, beispielsweise bei einem Aufprall eines Fußgängers ermöglichen. Jedoch werden beim Zuschlagen der Haube häufig höhere Kräfte in die Abstützung der Fronthaube eingeleitet als beim Aufprall des Fußgängers. Daher muss der Puffer des bekannten Vorderbaus eine sehr große Stabilität aufweisen, um ein Kollabieren beim Zuschlagen der Haube zu vermeiden. Diese hohe Stabilität des Puffers führt jedoch beim Aufprall des Fußgängers zu einem sehr großen Verletzungsrisiko.Such Front structures are commonly used in today's motor vehicles and are known from practice. In the known devices the buffer collapses at a given load and should a lowering of the hood, for example, in an impact of a Pedestrian enable. However, when you hit the hood often higher forces in the support of Front hood initiated as in the impact of the pedestrian. Therefore, the buffer must be the known front end have a very high stability to collapse to avoid when slamming the hood. This high stability of the buffer leads however on impact of the pedestrian too a very big one Risk of injury.
Der Erfindung liegt das Problem zugrunde, einen Vorderbau der eingangs genannten Art so weiterzubilden, dass sie einem Fußgänger bei einem Aufprall auf die Fronthaube einen möglichst hohen Schutz bietet und dass Betriebskräfte der Fronthaube zuverlässig abgestützt werden.Of the Invention is based on the problem, a front of the above educate so mentioned that they are a pedestrian an impact on the bonnet provides the highest possible protection and that operating staff the front hood reliable supported become.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass neben dem Puffer ein energieabsorbierendes Element angeordnet ist, und dass das energieabsorbierende Element zwischen der Fronthaube und dem Karosserieteil angeordnet ist und größere Abmessungen aufweist als der Puffer.This Problem is inventively characterized solved, that arranged next to the buffer, an energy absorbing element is, and that the energy absorbing element between the front hood and the body part is arranged and has larger dimensions than the buffer.
Durch diese Gestaltung werden die auf die Fronthaube einwirkenden Betriebskräfte von dem energieabsorbierenden Element und dem Puffer abgestützt. Das energieabsorbierende Element weist größere Abmessungen auf als der Puffer und ermöglicht daher eine großflächige Abstützung beim Zuschlagen der Fronthaube. Beim Aufprall des Fußgängers sind die Belastungen der Fronthaube jedoch örtlich begrenzt. Daher führt der örtlich begrenzte Aufprall des Fußgängers auf die Fronthaube zum Kollabieren des Puffers. Daher bietet der erfindungsgemäße Vorderbau einen besonders hohen Schutz für den Fußgänger beim Aufprall auf die Fronthaube. Das energieabsorbierende Element kann sich bei dem Aufprall im einfachsten Fall plastisch oder elastisch verformen. Vorzugsweise wird das energieabsorbierende Element beim Niederdrücken der Fronthaube plastisch verformt.By this design will affect the forces acting on the bonnet of the energy absorbing element and the buffer supported. The Energy absorbing element has larger dimensions than the Buffer and therefore allows a large-scale support during Slamming the front hood. When impact of the pedestrian are the loads the bonnet, however, localized. Therefore leads the local limited impact of the pedestrian the bonnet to collapse the buffer. Therefore, the front of the invention offers a very high protection for the pedestrian at Impact on the bonnet. The energy absorbing element can In the simplest case, the impact is plastic or elastic deform. Preferably, the energy absorbing element in Press down the bonnet plastically deformed.
Das energieabsorbierende Element könnte beispielsweise wie der Puffer des bekannten Vorderbaus einen runden Querschnitt aufweisen. Eine gleichmäßige Abstützung der Fronthaube über einen großen Bereich lässt sich jedoch gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach sicherstellen, wenn das energieabsorbierende Element quer zur Fahrtrichtung des Kraftfahr zeuges größere Abmessungen aufweist als in Fahrtrichtung des Kraftfahrzeuges.The For example, energy absorbing element could as the buffer of the known front building a round cross-section exhibit. A uniform support of the Front cover over a big Area leaves However, according to one simply ensure another advantageous development of the invention when the energy absorbing element is transverse to the direction of travel of the Kraftzeugs larger dimensions has as in the direction of travel of the motor vehicle.
Meist ist die Fronthaube an ihrem gegen die Fahrtrichtung weisenden Ende über Scharniere an dem Vorderbau angebunden. Hierbei lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung der Kraftverlauf beim Niederdrücken der Fronthaube nach dem Kollabieren des Puffes einfach über die gesamte Breite der Fronthaube festlegen, wenn das die Fronthaube abstützende Karosserieteil das Kraftfahrzeug in Fahrtrichtung begrenzt.Most of time is the front hood at her facing the direction of travel end hinges connected to the front building. This can be done according to a another advantageous embodiment of the invention, the force curve when pressing down the bonnet after collapsing the puff simply over the Set the entire width of the front hood, if that is the front hood supporting Body part limited the motor vehicle in the direction of travel.
Zur weiteren Vergleichmäßigung des Kraftverlaufs beim Niederdrücken der Fronthaube trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn sich das energieabsorbierende Element über die gesamte Breite des das Kraftfahrzeug in Fahrtrichtung begrenzenden Karosserieteils erstreckt.to further equalization of Force curve when depressing the front hood carries it according to one another advantageous embodiment of the invention, if the energy absorbing element across the entire width of the the motor vehicle extends in the direction of travel limiting body part.
Der erfindungsgemäße Vorderbau lässt sich besonders kostengünstig fertigen, wenn das energieabsorbierende Element einstückig aus Kunststoff gefertigt ist.Of the Front construction according to the invention can be special economical finished, when the energy absorbing element in one piece Plastic is made.
Zur Vereinfachung der Montage des energieabsorbierenden Elements trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn das energieabsorbierende Element einen Fuß aufweist und wenn der Fuß in dem Karosserieteil oder der Fronthaube befestigt ist.to Simplification of the assembly of the energy absorbing element contributes according to one another advantageous embodiment of the invention, when the energy absorbing element has a foot and when the foot in the Body part or the front hood is attached.
Das energieabsorbierende Element lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung aus kostengünstigen Gleichteilen zusammenstellen, wenn das energieabsorbierende Element mehrere, hintereinander gereihte Teilstücke aufweist.The Energy absorbing element can be according to a Another advantageous embodiment of the invention from inexpensive Assemble identical parts when the energy-absorbing element has several, sequenced sections.
Das Kollabieren des energieabsorbierenden Elements bei einer vorgesehenen Belastung auf die Fronthaube lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach festlegen, wenn der Puffer eine Sollbruchstelle aufweist.The Collapse of the energy absorbing element at a designated Load on the front hood leaves according to one determine another advantageous embodiment of the invention simply when the buffer has a predetermined breaking point.
Der erfindungsgemäße Vorderbau gestaltet sich konstruktiv besonders einfach, wenn das energieabsorbierende Element in einer Ausnehmung des Karosserieteils befestigt ist und an der Fronthaube anliegt.Of the Front construction according to the invention designed structurally particularly simple when the energy-absorbing Element is mounted in a recess of the body part and rests against the front hood.
