Abstract

A device for automatic opening of a flap of a car body which can pivot about a horizontal pivot axis, has a command transmitter. There is a gas spring-ejector combination whose gas spring (8) is linked with its ends on the flap and body sides to selected places relative to the pivot axis so that the gas spring with the flap found in the closed position and partly open position exerts a closing torque on this. On the other hand, with a wider open flap (2) it exerts an opening torque pivoting this into its fully open position. However the ejector is constructed to pivot the flap only partly over the partly open position and the command transmitter is assigned to it.

Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1. Bevorzugt handelt es sich bei diesen Klappen um Heckklappen oder hochschwenkbare Hecktüren von Kraftfahrzeugen.The invention relates to a device according to the preamble of patent claim 1. These flaps are preferably tailgates or can be swung up Rear doors of motor vehicles.

Neben Vorrichtungen, die ein Öffnen der Klappe (in dem eben definierten Sinne) durch Aufbringen der Öffnungskräfte von Hand ermöglichen, sind auch Vorrichtungen bekannt, die diesen Kraftaufwand dem Menschen abnehmen und hierzu Motoren verwenden. Ein Beispiel dafür gibt die DE 40 40 372 A1, bei der die Heckklappe vom Fahrzeuginnenraum her durch einen Fahrzeuginsassen mittels Einschalten eines Motors sich öffnen und schließen läßt. Nachteilig bei dieser Konstruktion ist zum einen der relativ große Energieaufwand, da der Motor offensichtlich die gesamte Öffnungsbewegung der Klappe vornehmen muß, und zum anderen die Tatsache, daß ein Öffnen der Heckklappe von außen auf diesem Wege nicht möglich ist.In addition to devices that open the flap (in the sense just defined) by To enable the application of the opening forces by hand, devices are also known who take this effort away from humans and use motors for this. On An example of this is DE 40 40 372 A1, in which the tailgate from Vehicle interior by a vehicle occupant by switching on an engine can be opened and closed. The disadvantage of this construction is the relative large energy expenditure, since the motor obviously the entire opening movement of the Must make flap, and secondly the fact that opening the tailgate is not possible from the outside in this way.

Den letztgenannten Nachteil vermeidet das System nach der DE 296 23 461 U1, das eine tragbare Fernsteuerung beinhaltet, die den Entriegelungs- und den Öffnungsvorgang der Klappe einleitet. In der Schrift ist erwähnt, daß dieses System generell für die Steuerung des Entriegelns und/oder Öffnens jeder Öffnungsvorrichtung eines Kraftfahrzeugs verwendet werden könne. Dieser Schrift ist nicht zu entnehmen, wie die eigentliche Öffnungsvorrichtung, also die Vorrichtung zur Erzeugung der Öffnungskräfte, aussehen soll.The latter disadvantage is avoided by the system according to DE 296 23 461 U1 includes a portable remote control that unlocks and Initiates the opening process of the flap. The Scripture mentions that this system generally for controlling the unlocking and / or opening of each opening device a motor vehicle can be used. This document does not show how the actual opening device, ie the device for generating the Opening forces, should look.

Die US-PS 5,369,911 beschreibt eine Kraftfahrzeugtür, die auf drahtlosem Wege entriegelbar ist und der ein dauernd unter Federspannung stehender Auswerfer zugeordnet ist. Sobald die betreffende Tür durch Aussenden und Empfangen eines Funksignals entriegelt ist, drückt der Auswerfer die Tür in eine Öffnungsstellung. US Pat. No. 5,369,911 describes a motor vehicle door that operates wirelessly can be unlocked and the ejector is constantly under spring tension assigned. As soon as the door in question by sending and receiving a Radio signal is unlocked, the ejector pushes the door into an open position.

Nachteilig bei dieser Konstruktion ist die Tatsache, daß der Auswerfer auch und gerade bei geschlossener Tür auf diese ein relativ großes im Öffnungssinne wirkendes Moment ausübt, das in dem Schloß der Tür aufgefangen werden muß, so daß das Entriegeln gegen relativ hohe Reibkräfte im Schloß erfolgen muß.A disadvantage of this construction is the fact that the ejector is also straight when the door is closed there is a relatively large moment in the opening sense exercises, which must be caught in the lock of the door, so that the unlocking against relatively high frictional forces in the lock.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, die einerseits völlige Freiheit hinsichtlich der Anordnung und Ausbildung des Befehlsgebers zuläßt (dieser kann als tragbarer Befehlsgeber zur Aussendung drahtloser Signale oder aber als Druckimpulsgeber am Fahrzeug ausgebildet sein), und die im übrigen ein vollständiges Öffnen der Klappe ohne Aufbringen von Kräften seitens einer Bedienungsperson sicherstellt, ohne daß bei in Schließstellung befindlicher Klappe in ihrem Schloß hohe Flächenpressungen und damit Reibungen in Kauf zu nehmen sind.The invention has for its object to a generic device create, on the one hand, complete freedom with regard to the arrangement and training of the Allows commanders (this can be used as a portable command transmitter for wireless transmission Signals or be designed as a pressure pulse generator on the vehicle), and in remaining a complete opening of the flap without applying any force on the part of one Operator ensures without in when the flap is in the closed position high pressures and thus friction must be accepted in their lock.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing Features of the main claim describe advantageous embodiments of the invention the subclaims.

Ein wesentliches Merkmal der Erfindung ist also in einer speziell ausgelegten Gasfeder-Auswerfer-Kombination zu sehen. Der Auswerfer ist nämlich so ausgelegt, daß er die Klappe - nach Entriegelung - aus ihrer geschlossenen Lage lediglich bis etwas über eine teilgeöffnete Stellung hinaus öffnet, in der die Gasfeder infolge geeigneter Wahl ihrer Angriffsstellen an Karosserie und Klappe beginnt, auf die letztere ein Öffnungsmoment auszuüben (bei kleineren Öffnungsstellungen der Klappe übt die Gasfeder ein Schließmoment aus). Man kann also sagen, daß die Gasfeder eine Totpunktstellung bei der definierten teilgeöffneten Lage der Klappe besitzt, und daß der Auswerfer lediglich so ausgelegt ist, daß er die Totpunktstellung der Gasfeder gleichsam überfährt; die weitere Öffnungsbewegung erfolgt dann ohne Energiezufuhr, nämlich allein unter der Wirkung der in der Gasfeder gespeicherten Energie.An essential feature of the invention is therefore in a specially designed gas spring ejector combination to see. The ejector is designed so that it Flap - after unlocking - from its closed position only to a little over one partially open position also opens in which the gas spring due to a suitable choice of their Attacks on the body and flap begin, the latter an opening moment exercise (with smaller opening positions of the flap the gas spring exercises Closing torque off). So you can say that the gas spring is in a dead center position has the defined partially open position of the flap, and that the ejector only so is designed so that it passes over the dead center position of the gas spring; the further The opening movement then takes place without the supply of energy, namely solely under the effect the energy stored in the gas spring.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert, die, teilweise im Schnitt, die Verhältnisse im Bereich einer hier die Klappe darstellenden hochschwenkbaren Hecktür eines PKW zeigt.An embodiment of the invention is described below with reference to the drawing explains the, partly in section, the conditions in the area of a flap here showing swing-up tailgate of a car.

Zur Abdeckung einer Hecköffnung in dem hinteren Karosseriebereich 1 dient die Hecktür 2 an sich bekannten und daher nicht zu beschreibenden Aufbaus. Erwähnt sei lediglich, daß sie bei 3 ein Heckfenster enthält und bei 4 einen Aufnahmebereich für das Nummernschild bildet. Die Hecktür ist über die querverlaufende Schwenkachse 5 zwischen ihrer Schließlage 2 und ihrer Öffnungslage 2' verschwenkbar. Zur Arretierung der Hecktür 2 in ihrer Schließstellung dient das bei 6 angedeutete Schloß ebenfalls bekannter Bauart, beispielsweise ein Drehfallenschloß.The rear door serves to cover a rear opening in the rear body area 1 2 known and therefore not to be described structure. Just mention that it contains a rear window at 3 and at 4 a recording area for the License plate forms. The tailgate is over the transverse pivot axis 5 pivotable between its closed position 2 and its open position 2 '. For locking the tailgate 2 in its closed position also serves the lock indicated at 6 known type, for example a rotary latch lock.

Zum selbsttätigen Öffnen der Hecktür 2, das heißt zum Hochachwenken in ihre voll geöffnete Stellung 2', nach Aussenden eines drahtlosen Befehls mittels des lnfrarotsensors 7, der beispielsweise in einen Fahrzeugschlüssel integriert sein kann, dient die Gasfeder-Auswerfer-Kombination mit der einen üblichen Aufbau besitzenden Gasfeder 8 und dem durch eine Kolben-Zylinder-Anordnung gebildeten Auswerfer 9. Während dieser nur in der Karosserie 1 festgelegt ist und mit seinem in der Figur rechten freien Ende lediglich druckübertragend auf einem Bereich der Hecktür 2 aufliegt, ist die Gasfeder 8 mit ihren Enden teils bei 10 an der Karosserie 1, teils bei 11 an der Hecktür 2 schwenkbar angelegt. Die Ausrichtung der Achse der Gasfeder 8 ist durch geeignete Wahl ihrer Anlenkungen 10 und 11 bezüglich der Schwenkachse 5 der Hecktür 2 so gewählt, daß sie in einem sich zwischen ihrer voll geschlossenen Lage und einer teilgeöffneten Lage erstreckenden Schwenkbereich der Tür auf diese ein Schließmoment ausübt, dagegen darüber gleichsam in Übertotpunktlagen ein Öffnungsmoment, das ausreicht, um die Hecktür 2 in ihre voll geöffnete Stellung 2' zu verschwenken.To automatically open the tailgate 2, that is to swing up in its full open position 2 ', after sending a wireless command using the Infrared sensor 7, which can be integrated into a vehicle key, for example, serves the gas spring ejector combination with the usual structure Gas spring 8 and the ejector 9 formed by a piston-cylinder arrangement. While this is only fixed in the body 1 and with his right in the figure free end rests only pressure-transmitting on an area of the tailgate 2, is the Gas springs 8 with their ends partly at 10 on the body 1, partly at 11 on the rear door 2 pivoted. The alignment of the axis of the gas spring 8 is suitable Choice of their linkages 10 and 11 with respect to the pivot axis 5 of the tailgate 2 so chosen to be in a position between its fully closed position and one partially open position extending pivoting range of the door to this a closing moment exerts an opening moment above it, as it were, in over-dead center positions, the is sufficient to pivot the tailgate 2 into its fully open position 2 '.

Der Auswerfer 9 dagegen ist so ausgelegt, daß er durch Energiezufuhr in seine in der Zeichnung linken Kammer seine Kolbenstange lediglich so weit ausfährt, daß diese die Hecktür 2 etwas über ihre definierte teilgeöffnete Stellung hinaus in eine Lage verschwenkt, in der die Gasfeder 8 ein öffnendes Moment auf die Hecktür 2 ausübt. Dadurch ist sichergestellt, daß der weitaus größte Teil der Öffnungsbewegung der Heckklappe 2, noch dazu derjenige, bei dem das Gewicht der Heckklappe ein Schließmoment erzeugt, ohne Energiezufuhr allein durch die in der Gasfeder 8 gespeicherte Energie erfolgt. Der Auswerfer 9 fährt dann wieder in seine Ausgangslage.The ejector 9, on the other hand, is designed in such a way that it is supplied with energy in its Drawing left chamber only extends its piston rod so far that this Tailgate 2 slightly beyond its defined partially open position pivoted, in which the gas spring 8 exerts an opening moment on the rear door 2. This ensures that the vast majority of the opening movement of the Tailgate 2, especially the one with the weight of the tailgate Closing torque generated without energy supply solely by the gas spring 8 stored energy takes place. The ejector 9 then moves back to its starting position.

Wie bereits erwähnt, wird die Öffnungsbewegung der Hecktür 2 eingeleitet durch ein Signal von dem tragbaren Befehlsgeber 7. Dieses drahtlose Signal wird im Empfänger 12 empfangen und so verarbeitet, daß dieser die Steuereinheit 13 im Sinne der Beaufschlagung der in der Zeichnung linken Kammer des Auswerters 9 ansteuert. In dem gezeichneten Ausführungsbespiel erfolgt die Betätigung des Auswerfers 9 durch Zufuhr von pneumatischer Energie; auch andere Energieformen können Einsatz finden.As already mentioned, the opening movement of the tailgate 2 is initiated by a Signal from the portable command transmitter 7. This wireless signal is in the receiver 12 received and processed so that the control unit 13 in the sense of Actuation of the left chamber in the drawing of the evaluator 9 controls. In the exemplary embodiment shown actuates the ejector 9 by Supply of pneumatic energy; other forms of energy can also be used.

Selbstverständlich muß, bevor die Öffnungsbewegung der Heckklappe 2 beginnt, das Schloß 6 entriegelt werden; dies ist durch die Signalleitung 14 angedeutet.Of course, before the opening movement of the tailgate 2 begins, the Lock 6 to be unlocked; this is indicated by the signal line 14.

Da die Gasfeder 8 bei geschlossener Hecktür 2 auf diese ein - wenn auch geringes - Schließmoment ausübt, sind die zusammenwirkenden Schloßbestandteile des Schlosses 6 während ihrer Entriegelungsbewegungen weitgehend druckkraftentlastet, so daß hohe Reibkräfte vermieden sind. Das gilt auch, wenn der Auswerfer 9 mit seinem freien Stößelende mit einer gewissen Kraft auf dem ihn zugekehrten Bereich der Hecktür 2 aufliegt.Since the gas spring 8 with a closed tailgate 2 on this one - albeit a little - Exerts a closing moment, are the interacting components of the lock 6 largely relieved of pressure during their unlocking movements, so that high Frictional forces are avoided. This also applies if the ejector 9 with its free End of the plunger with a certain force on the area of the tailgate 2 facing him lies on.

Mit der Erfindung ist demgemäß eine gattungsgemäße Vorrichtung geschaffen, die bei geringem zusätzlichen Aufwand, noch dazu an an sich bekannten und bewährten Baugruppen, in energieoptimierter Weise ein automatisches Öffnen einer Kraftfahrzeug-Heckklappe ermöglicht.With the invention, a generic device is accordingly created, which at little additional effort, in addition to known and proven Assemblies, an automatic opening of a motor vehicle tailgate in an energy-optimized manner enables.
