Abstract
Description
Die Erfindung betrifft eine Anordnung einer Frontklappe an einem Fahrzeug.The The invention relates to an arrangement of a front flap on a vehicle.
Um bei einer Kollision eines Fußgängers oder Radfahrers mit einem Kraftfahrzeug das Ausmaß von Verletzungen, insbesondere im Brust- und Kopfbereich, zu reduzieren, ist es allgemein bekannt, die Frontklappe zumindest bereichsweise mit zumindest einem Aktuator anzuheben. Hierdurch wird ein so großer Abstand der Frontklappe zu einer steifen Unterstruktur des Fahrzeugs (Motor, Federbeinaufnahmen, etc.) erreicht, dass ein ausreichender Deformationsweg zur Verfügung steht, um den Aufprall des Fußgängers oder Radfahrers auf ein verträgliches Maß zu verzögern.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 that Front flap at least partially with at least one actuator to raise. This will be such a large distance of the front door to a stiff substructure of the vehicle (engine, strut mountings, etc.), that a sufficient deformation path is available, to the impact of the pedestrian or Cyclist on a tolerable Measure too delay.
Aufgabe der Erfindung ist es, eine Anordnung einer Frontklappe an einem Fahrzeug zu schaffen, die einen aufprallenden Fußgänger oder Radfahrer möglichst gut vor Verletzungen schützt.task The invention is an arrangement of a front door on a Vehicle to create the impact of a pedestrian or cyclist possible protects well from injuries.
Diese Aufgabe wird mit einer Anordnung einer Frontklappe an einem Fahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with an arrangement of a front door on a vehicle solved with the features of claim 1.
Erfindungsgemäß ist eine Frontklappe – in Fahrtrichtung gesehen – im hinteren Bereich über zumindest ein Mehrgelenkscharnier mit einer Karosserie des Fahrzeugs verbunden, um das die Frontklappe zum normalen Öffnen und Schließen verschwenkbar ist. Zwischen dem Mehrgelenkscharnier und der Karosserie ist zumindest ein Aktuator angeordnet, der das Mehrgelenkscharnier und damit die Frontklappe im hinteren Bereich anhebt, wenn eine Kollision des Fahrzeugs mit einem Fußgänger oder Radfahrer detektiert wird. Dabei ist die Frontklappe im vorderen Bereich über mindestens ein Klappenschloss oder über vordere Aktuatoren so mit der Karosserie verbunden, dass die Frontklappe beim Anheben im hinteren Bereich gegenüber der geschlossenen Stellung um eine Achse parallel zur Schwenkachse des Mehrgelenkscharniers verkippt. Durch dieses Verkippen wird ein Verschwenken des Mehrgelenkscharniers erzwungen, wodurch die Frontklappe aufgrund der Kinematik des Mehrgelenkscharniers zusätzlich im hinteren Bereich angehoben wird. Der gesamte Anhebeweg der Frontklappe im hinteren Bereich setzt sich also zusammen aus einem Anhebeweg durch den zumindest einen Aktuator zwischen dem Mehrgelenkscharnier und der Karosserie und einem Anhebeweg, der aus dem zwangsweisen Verschwenken des Mehrgelenkscharniers resultiert. Der Anhebeweg zum Erzeugen des erforderlichen Mindestabstandes zwischen Frontklappe und den darunter liegenden Aggregaten muss also nicht vollständig vom Aktuator erzeugt werden. Dadurch kann ein kleinerer Aktuator verwendet werden, der ein geringeres Gewicht aufweist und auch mit geringeren Kosten verbunden ist.According to the invention is a Front flap - in the direction of travel seen - im rear area over at least one multi-joint hinge with a body of the vehicle connected to the front door for normal opening and closing pivot is. Between the multi-joint hinge and the body is at least arranged an actuator, which is the multi-joint hinge and thus the Front flap in the rear area raises when a collision of the Vehicle with a pedestrian or Cyclist is detected. The front flap is in the front Area over at least one flap lock or via front actuators so with the body connected to the front flap when lifting in the rear Area opposite the closed position about an axis parallel to the pivot axis tilted the multi-joint hinge. This tilting becomes a Forced pivoting of the multi-joint hinge, eliminating the front door due to the kinematics of the multi - joint hinge in addition rear area is raised. The entire lifting of the front flap in the rear area is thus composed of a trailer by the at least one actuator between the multi-joint hinge and the bodywork and a lifting, resulting from the forced pivoting of the multi-joint hinge results. The crop to produce the required minimum distance between the front flap and the below lying aggregates must therefore not be generated completely by the actuator. As a result, a smaller actuator can be used, the lower one Has weight and is also associated with lower costs.
Vorteilhafterweise ist zumindest ein Gelenk des Mehrgelenkscharniers durch ein Federelement mit einer Federkraft beaufschlagt, sodass die Zwangsverschwenkung unterstützt wird. Das Kräfteverhältnis im Mehrgelenkscharnier ist zu Beginn der Zwangsverschwenkung aufgrund der Hebelarme relativ ungünstig. Durch den unterstützenden Einsatz mindestens eines Federelementes können diese Nachteile überwunden werden, sodass die erforderlichen Kräfte zum Zwangsverschwenken des Mehrgelenkscharniers deutlich geringer als ohne unterstützende Federelemente sind. Auch die im Mehrgelenkscharnier herrschenden Reibungskräfte können so kompensiert werden.advantageously, is at least one joint of the multi-joint hinge by a spring element with a spring force applied, so that the Zwangsverschwenkung is supported. The balance of power in Multi-joint hinge is due to at the beginning of Zwangsverschwenkung the lever arms relatively unfavorable. By the supportive Use of at least one spring element can overcome these disadvantages so that the required forces for Zwangsverschwenken of the multi-joint hinge significantly lower than without supporting spring elements are. The friction forces prevailing in the multi-joint hinge can thus be compensated become.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, anhand dessen die Erfindung im folgenden näher beschrieben wird. Die einzige Figur zeigt in schematischer Darstellungsweise eine Seitenansicht eines Mehrgelenkscharniers, über das eine Frontklappe an eine Karosserie eines Personenkraftwagens angelenkt ist.In the drawing is an embodiment of Invention, according to which the invention in the following described in more detail becomes. The single figure shows a schematic representation of a Side view of a multi-joint hinge, over which a front flap a body of a passenger car is articulated.
In
der Figur ist ein Viergelenkscharnier
Die
Frontklappe ist in Fahrtrichtung gesehen im hinteren Bereich beidseitig
jeweils mit einem oberen Scharnierträger
Wenn
nun eine Kollision des Personenkraftwagens mit einem Fußgänger oder
Radfahrer detektiert wird, werden die beiden Aktuatoren aktiviert.
Diese heben schlagartig die beiden Viergelenkscharniere 1 um ca.
50 mm an. Dadurch wird automatisch auch die Frontklappe im hinteren
Bereich um diese 50 mm angehoben. Dabei bleibt das Klappenschloss geschlossen.
Dies führt
zu einem Kippen der Frontklappe um eine Achse in Fahrzeugquerrichtung,
die parallel zu der tatsächlichen
Schwenkachse der Viergelenkscharniere
Bei
dem zwangsweisen Verschwenken im Viergelenkscharnier
Durch
das Anheben der Frontklappe im hinteren Bereich um ca. 80 mm ist
der Abstand zwischen der Frontklappe und den darunter liegenden Aggregaten
so groß,
dass sich die Frontklappe unter der Last des aufprallenden Fußgängers oder
Radfahrers so stark verformen kann, dass das Verletzungsrisiko bei
diesem relativ gering ist. Die zur Deformation erforderlichen Kräfte sind
zu Beginn der Deformation niedrig, es ist keine hohe Anfangskraft
aufzubringen, da anfangs nur die Federkraft der Feder
