Description

Türaußengriff für ein Kraftfahrzeug Outside door handle for a motor vehicle
Die Erfindung betrifft einen Türaußengriff für ein Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to an outside door handle for a motor vehicle according to the preamble of claim 1.
Ein Türaußengriff mit zwei von einem Griffteil abstehenden Schwenkhebeln, die jeweils am freien Ende der Schwenkhebel um eine gemeinsame Schwenkachse in einem Griffgehäuse schwenkbar sind, ist beispielsweise aus der DE 100 15 887 C bekannt. Bei einer Hub- oder Ziehbewegung an dem Griffteil kann das Türschloss einer Kraftfahrzeugtür geöffnet werden. Bei elektromechanischen Schließsystemen besteht das Problem, dass bei einem Systemausfall oder Stromausfall der Zugang zu dem Kraftfahrzeug verwehrt bleibt.An outside door handle with two pivoting levers projecting from a handle part, which are each pivotable about a common pivot axis in a handle housing at the free end of the pivot lever, is known, for example, from DE 100 15 887 C. During a lifting or pulling movement on the handle part, the door lock of a motor vehicle door can be opened. Electromechanical locking systems have the problem that in the event of a system failure or power failure, access to the motor vehicle is denied.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Türaußengriff für ein Kraftfahrzeug zu schaffen, bei dem im Falle eines System- oder Stromausfalls dennoch der Zugang zum Inneren des Fahrzeugs ermöglicht wird.The invention is therefore an object of the invention to provide an outside door handle for a motor vehicle in which in the event of a system or power failure, access to the interior of the vehicle is still possible.
Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1. Die Erfindung sieht in vorteilhafter Weise vor, dass die Hubbewegung des Griffteils unterteilt ist, wobei am Ende eines ersten Hubweges eine Einrichtung einen erhöhten Betätigungswiderstand erzeugt und ein Schalter das Schloss elektrisch öffnet, wobei im Falle eines Ausfalls der elektrischen Stromversorgung oder des elektrischen Schließsystems das Griffteil über den ersten Hubweg hinaus einen zusätzlichen Hubweg ausführen kann, der das Türschloss mechanisch öffnet.To solve this problem serve the features of claim 1. The invention provides in an advantageous manner that the lifting movement of the handle part is divided, wherein at the end of a first stroke a device generates an increased actuation resistance and a switch opens the lock electrically, wherein in case of failure of the electrical power supply or the electrical locking system, the handle part beyond the first stroke can perform an additional stroke, which opens the door lock mechanically.
Ein solcher Türaußengriff kann in üblicher Weise betätigt werden, wobei der erhöhte Betätigungswiderstand am Ende des ersten Hubwegs und die elektrische Öffnung des Türschlosses der Bedienungsperson das ihr bekannte Gefühl einer mechanischen Türöffnung vermittelt.Such an outside door handle can be actuated in a conventional manner, wherein the increased operating resistance at the end of the first stroke and the electrical opening of the door lock of the operator conveys the familiar feeling of a mechanical door opening.
Im Falle eines Ausfalls der elektrischen Stromversorgung oder eines sonstigen Ausfalls des elektrischen Teils des Schließsystems, kann das Griffteil über den ersten Hubweg hinaus weiter betätigt werden, um das Türschloss in an sich bekannter Weise mechanisch zu öffnen. Hierzu wird über einem Schwenkhebel des Griffteils ein Schwenkhebel betätigt, der über einen Bowdenzug mechanisch das Schloss öffnet.In the event of a failure of the electrical power supply or other failure of the electrical part of the locking system, the handle part can be operated beyond the first stroke further to mechanically open the door lock in a conventional manner. For this purpose, a pivot lever is actuated via a pivot lever of the handle part, which mechanically opens the lock via a Bowden cable.
Am Ende des ersten Hubweges wirkt eine Einrichtung auf das Griffteil ein, die den Betätigungswiderstand kurzfristig erhöht und zwar in der Art eines an dem Griffteil spürbaren und zu überwindenden Druckpunktes mit nachfolgendem Anschlag.At the end of the first stroke, a device acts on the handle part, which increases the operating resistance in the short term in the manner of a felt on the handle part and to be overcome pressure point with subsequent stop.
Die Einrichtung zum Erhöhen des Betätigungswiderstandes besteht aus mindestens einer Dämpfungseinrichtung, die unter Druckeinwirkung verformbar ist, wobei zur Verformung zunächst eine erhöhte Kraftschwelle überwunden werden muss. Der Schalter zur elektrischen Betätigung des Türschlosses öffnet vorzugsweise nach, oder bei Überwindung des von der Einrichtung zum Erhöhen des Betätigungswiderstandes erzeugten Druckpunktes des Türschloss.The device for increasing the actuation resistance consists of at least one damping device which is deformable under the action of pressure, wherein initially an increased force threshold has to be overcome for deformation. The switch for the electrical actuation of the door lock preferably opens, or upon overcoming the pressure point of the door lock generated by the device for increasing the operating resistance.
Der elektrische Schalter kann aus einem Mikroschalter, einem Hallsensor, einem kapazitiver Sensor, einem Reedschalter oder einem Beschleunigungssensor bestehen,The electrical switch may consist of a microswitch, a Hall sensor, a capacitive sensor, a reed switch or an acceleration sensor,
Die Einrichtung zur Erhöhung des Betätigungswiderstandes kann aus einer mit dem Griffteil bzw. einem Schwenkhebel des Griffteils mechanisch starr gekoppelten Platte bestehen, die am Ende des ersten Hubweges auf eine Dämpfungseinrichtung aus mindestens einem napfartigeπ Verformungselement aus elastischem Material einwirkt. Das napfartige Verformungselement, vorzugsweise aus einem Gummimaterial, kann sprunghaft seine Form ändern, wobei der Kraftaufwand zur Verformung kurzfristig um ein mehrfaches, beispielsweise das Vierfache des Kraftaufwandes zum Verschwenken des Griffteils ansteigen kann. Nach Kompression der Dämpfungseinrichtung ist bei der Griffbetätigung ein Anschlag spürbar, der dadurch entsteht, dass einer der Schwenkhebel des Griffteils gegen einen in Gegenrichtung unter Federbelastung vorgespannten Schwenkhebel für die mechanische Betätigung des Türschlosses anstößt. Die Dämpfungseinrichtung ist mit einem Schwenkhebel für die mechanische Türschlossöffnung gekoppelt.The device for increasing the actuating resistance may consist of a mechanically rigidly coupled to the handle part or a pivot lever of the handle member plate which acts at the end of the first stroke on a damping device of at least one cupfartigeπ deformation element made of elastic material. The cup-like deformation element, preferably made of a rubber material, can change its shape abruptly, wherein the force required for deformation in the short term by a multiple, for example, four times the force required to pivot the handle part can increase. After compression of the damping device, a stop is felt in the handle operation, which arises because one of the pivot lever of the handle abuts against a biased in the opposite direction under spring load pivot lever for the mechanical operation of the door lock. The damping device is coupled to a pivot lever for the mechanical door lock opening.
Das Griffteil kann bei einer fortgesetzten Hubbewegung über den von der Dämpfungseinrichtung gebildeten Anschlag hinaus den Schwenkhebel für die mechanische Türschlossöffnung mitnehmen, um mit einem mit dem Schwenkhebel gekoppelten Bowdenzug das Türschloss mechanisch zu öffnen.The handle member may take the pivot lever for the mechanical door lock opening with a continued lifting movement over the stop formed by the damping device out to mechanically open the door lock with a coupled with the pivot lever Bowden cable.
Bei einer alternativen Lösung ist vorgesehen, dass ein Hubmagnet mit einem Sperrbolzen bei funktionierender Stromversorgung die Hubbewegung des Griffteils auf den ersten Hubweg durch Bildung eines Anschlages mit dem Sperrbolzen begrenzt und dass im Falle eines Stromausfalls der Hubmagnet den Sperrbolzen zurückzieht und das Griffteil für einen zusätzlichen Hubweg zur mechanischen Öffnung des Türschlosses freigibt.In an alternative solution it is provided that a solenoid with a locking pin when the power supply is functioning, the lifting movement of the handle on the first stroke by forming a stop with the Locking pin limits and that in case of power failure, the solenoid retracts the locking pin and releases the handle for an additional stroke for mechanical opening of the door lock.
Zusammenfassend ermöglicht die Erfindung in vorteilhafter Weise, dass der Türaußengriff bei funktionierendem elektromechanischen Schließsystem in gewohnter Weise mit dem für eine Bedienungsperson gewohnten Betätigungsgefühl eine Tür öffnen kann. Im Falle eines Stromausfalls oder eines Systemausfalls, z.B. bei Ausfall einer Steuerleitung, kann durch weiteres Ziehen oder Anheben des Türaußengriffs die Tür rein mechanisch mit Hilfe eine mechanischen Schlüssels und dem vollständigen Hub des Griffteils geöffnet werden.In summary, the invention advantageously makes it possible for the outside door handle to be able to open a door in the usual manner with the operating feeling familiar to an operator while the electromechanical locking system is functioning. In case of power failure or system failure, e.g. in case of failure of a control line, the door can be opened purely mechanically by means of a mechanical key and the complete stroke of the handle by further pulling or lifting the outside door handle.
Ist nur eine Steuerleitung des elektromechanischen Schließsystems, oder lediglich ein elektrischer Schalter des elektro-mechanischen Schließsystems defekt, kann in solchen Fällen dennoch das Fahrzeug gestartet werden.If only one control line of the electromechanical locking system, or only an electrical switch of the electromechanical locking system is defective, the vehicle can nevertheless be started in such cases.
Die Erfindung ist auf alle Arten von Türaußengriffen anwendbar und insbesondere nicht auf Klappgriffe beschränkt. Sie ist auch für Ziehgriffe und Zieh- Schwenkgriffe mit geneigter Schwenkachse oder Ziehgriffe mit im Wesentlichen vertikaler Schwenkachse geeignet.The invention is applicable to all types of outside door handles and in particular not limited to hinged handles. It is also suitable for pull handles and pull swivel handles with tilted pivot axis or pull handles with substantially vertical pivot axis.
Im Folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained in more detail with reference to the drawings.

Fig. 5 zeigt einen Ausschnitt einer Tür 11 eines Kraftfahrzeuges mit einem Türaußengriff 3, der ein manuell betätigbares Griffteil 3 aufweist. Das Griffteil 3 kann zum Öffnen des Türschlosses durch eine Hub- oder Ziehbewegung betätigt werden. Zum Öffnen der Fahrzeugtür 11 wird ein elektromechanisches Schließsystem 2 aktiviert, mit dessen Hilfe das Türschloss 8 geöffnet und geschlossen werden kann. Das Griffteil 3 hat zwei mit Abstand voneinander angeordnete Schwenkhebel 4a, 4b, die um eine gemeinsame Achse 5 im Griffgehäuse 13 verschwenkbar sind. Zur Realisierung eines Schwenk-Ziehgriffes kann die Achse 5 auch nicht parallel zu dem Griffteil 3 verlaufen.5 shows a detail of a door 11 of a motor vehicle with an outside door handle 3, which has a manually operable grip part 3. The handle part 3 can be actuated to open the door lock by a lifting or pulling movement. To open the vehicle door 11, an electromechanical locking system 2 is activated, with the aid of which the door lock 8 can be opened and closed. The handle part 3 has two spaced-apart pivot lever 4a, 4b, which are pivotable about a common axis 5 in the handle housing 13. To realize a swivel-pull handle, the axis 5 can not run parallel to the handle part 3.
An mindestens einem der Schwenkhebel 4a, 4b kann eine Einrichtung 9 zum Erhöhen des Betätigungswiderstandes angeordnet sein, die am Ende eines ersten Hubweges 21 in den Eingriff kommt.At least one of the pivoting levers 4a, 4b may be arranged a device 9 for increasing the operating resistance, which comes at the end of a first stroke 21 into engagement.
Wie aus den Fign. 1 und 2 ersichtlich ist die Einrichtung zur Erhöhung des Betätigungswiderstandes am unteren Ende des Schwenkhebelabschnitts 4a angeordnet und besteht im Einzelnen aus einer an dem Schwenkhebelabschnitt 4a starr verbundenen Platte 10 mit Vorsprüngen 16, die am Ende des ersten Hubweges 21 auf napfartige Verformungselemente 14 einwirken, bei denen zur Verformung zunächst eine erhöhte Kraftschwelle überwunden werden muss. Die napfartigen Verformungselemente 14 aus elastischem Material verformen sich in der aus den Fign. 4a, 4b ersichtlichen Weise, wobei zum Flachdrücken des Oberteils der Verformungselemente eine erhöhte Betätigungskraft ausgeübt werden muss. Diese erhöhte Betätigungskraft ist bei der Betätigung des Griffteils 3 als ein zu überwindender Druckpunkt zu empfinden, so dass für den Benutzer der Eindruck einer mechanischen Öffnung des Türschlosses 8 entsteht.As shown in Figs. 1 and 2, the device for increasing the actuating resistance at the lower end of the pivot lever portion 4a is arranged and consists in detail of a rigidly connected to the pivot lever portion 4a plate 10 with projections 16 which act at the end of the first stroke 21 on cup-shaped deformation elements 14 at which initially an increased force threshold must be overcome for deformation. The cup-shaped deformation elements 14 made of elastic material deform in the form shown in FIGS. 4a, 4b apparent manner, wherein for flattening the upper part of the deformation elements, an increased actuation force must be exerted. This increased operating force is in the operation of the handle part 3 as a pressure point to be overcome, so that the impression of a mechanical opening of the door lock 8 is created for the user.
Bei Verformung der napfartigen Verformungselemente oder kurz nach dem Überwinden des Druckpunktes, wird ein Schalter 20 von einem Vorsprung 22 am unteren Ende des Schwenkhebels 4a betätigt.Upon deformation of the cup-like deformation elements or shortly after overcoming the pressure point, a switch 20 is actuated by a projection 22 at the lower end of the pivot lever 4a.
Rg. 2 zeigt den Schwenkhebel 4a, 4b in einer Position kurz vor dem Ende des ersten Hubweges 21. Die in Fig. 2 eingezeichneten Winkellagen beziehen sich auf den Schwenkhebelabschnitt 4a und zeigen dessen Position in der Ruhelage 15, in einer Mittellage 17 am Ende des ersten Hubweges 21, und in einer Endlage 19 am Ende des weiteren Hubweges 23 nach dem mechanischen Öffnen des Türschlosses 8.FIG. 2 shows the pivot lever 4a, 4b in a position shortly before the end of the first stroke 21. The angular positions shown in FIG. 2 relate to the pivot lever section 4a and show its position in the rest position 15, in a central position 17 at the end of the pivot first stroke 21, and in an end position 19 at the end of the further stroke 23 after the mechanical opening of the door lock. 8
Die napfartigen Verformungselemente 14 aus elastischem Material, vorzugsweise einem Gummimaterial, sind auf einer Stützplatte 12 angeordnet, die mit einem weiteren Schwenkhebel 6 über einen Quersteg 18 verbunden ist. Der Schwenkhebel 6 dient zur mechanischen Öffnung des Türschlosses 8, wenn das Griffteil 3 mit dem Schwenkhebelabschnitt 4a über die Mittellage 17 hinaus verschwenkt wird. Der Schwenkhebel 6 wird mit Hilfe einer im Gehäuse 13 gelagerten Feder 28 in Gegenrichtung zu der in Fig. 2 gezeigten Betätigungsrichtung des Griffteils 3 vorgespannt, so dass der Schwenkhebel 6 mit der Stützplatte 12 und den darauf befestigten Verformungselementen 14 einen überwindbaren Anschlag für den ersten Hubweg 21 bildet.The cup-like deformation elements 14 of elastic material, preferably a rubber material, are arranged on a support plate 12, which is connected to a further pivot lever 6 via a transverse web 18. The pivot lever 6 is used for mechanical opening of the door lock 8, when the handle part 3 is pivoted with the pivot lever portion 4a on the central position 17 addition. The pivot lever 6 is biased by means of a spring 28 mounted in the housing 13 in the opposite direction to the direction of actuation of the handle part 3 shown in FIG. 2, so that the pivot lever 6 with the support plate 12 and the deformation elements 14 mounted thereon a surmountable stop for the first stroke 21 forms.
Der Schwenkhebel 6 ist um eine in dem Gehäuse 13 gelagerte Schwenkachse 7 verschwenkbar, wobei an dem Schwenkhebel 6 eine Bowdenzugaufnahme 30 für einen Bowdenzug 32 befestigt ist, so dass bei einer Schwenkbewegung des Schwenkhebels 6 der Bowdenzug 32 betätigt wird, um das Türschloss 8 mechanisch zu öffnen. Eine Schwenkbewegung des Schwenkhebels 6 wird eingeleitet, wenn im Falle eines Stromausfalls oder eines Ausfalls des elektrischen Teils des Schließsystems das Griffteil 3 über den ersten Hubweg 21 hinaus weiter verschwenkt wird, indem wie aus Fig. 3 am besten ersichtlich der Schwenkhebelabschnitt 4a den Quersteg 18 des Schwenkhebels 6 mitnimmt.The pivot lever 6 is pivotable about a mounted in the housing 13 pivot axis 7, wherein on the pivot lever 6, a Bowdenzugaufnahme 30 is attached to a Bowden cable 32 so that upon pivotal movement of the pivot lever 6 of the Bowden cable 32 is actuated to the door lock 8 mechanically to open. A pivoting movement of the pivot lever 6 is initiated when, in the event of a power failure or a failure of the electrical part of the locking system, the handle part 3 is further pivoted beyond the first stroke 21, as best seen in Fig. 3, the pivot lever portion 4a the cross bar 18 of Swing lever 6 entrains.
Es ist somit bei einem Stromausfall oder bei einem Ausfall einer Steuerleitung des Schließsystems 2 möglich, mit einem mechanischen Schlüssel den Schließzylinder 15 zu betätigen und die Tür durch Betätigung des Griffteils 3 mechanisch zu öffnen.It is thus possible in case of power failure or failure of a control line of the locking system 2, to operate the lock cylinder 15 with a mechanical key and to open the door mechanically by operating the handle part 3.
Wie aus Fig. 3 ersichtlich, können beispielsweise auf der Stützplatte 12 vier Verformungselemente angeordnet sein.As can be seen from FIG. 3, for example, four deformation elements can be arranged on the support plate 12.
Der Vorteil, der in den Fign. 4a und 4b dargestellten Verformungselemente besteht darin, dass zum Flachdrücken des napfartigen Teils des Verformungselementes zunächst eine erhöhte Kraftschwelle überwunden werden muss.The advantage that is shown in FIGS. 4a and 4b illustrated deformation elements is that for flattening the cup-like part of the deformation element initially an increased force threshold must be overcome.
Dadurch wird bei Betätigung des Griffteils 3 das Gefühl der Überwindung eines Druckpunktes am Ende des ersten Hubweges 21 erzeugt, so dass der Öffnungsvorgang einer Tür 11 bei ordnungsgemäß funktionierendem Schließsystem 2 und vorhandener Stromversorgung, nach Überwindung des Druckpunktes und elektrischer Öffnung des Türschlosses 8 beendet werden kann. As a result, upon actuation of the handle part 3, the feeling of overcoming a pressure point at the end of the first stroke 21 is generated, so that the opening operation of a door 11 can be terminated with properly functioning locking system 2 and existing power supply, after overcoming the pressure point and electrical opening of the door lock 8 ,
