Description

Fahrzeugschlussel für fernbedienbare Fahrzeugschließsysteme Vehicle key for remote-controlled vehicle locking systems
Beschreibung:Description:
Die Erfindung betrifft einen Fahrzeugschlussel für fernbedienbare Fahrzeugschließsysteme. - Ein derartiger Fahrzeugschlussel wird auch als elektronischer Schlüssel bezeich- net . Unter fernbedienbare Fahrzeugschließsysteme sind sowohl mit einer mechanisch betätigbaren Fernbedienung ausgerüstete Schließsysteme als auch solche mit einer Spule in einem sogenannten "Scheckkarten"- bzw. Sendergehäuse ausgestattete Schließsysteme zu verstehen, bei denen der Schließbetrieb automatisch, beispielsweise bei Betätigung des Türgriffes - in Gang gesetzt wird.The invention relates to a vehicle key for remote-controlled vehicle locking systems. Such a vehicle key is also referred to as an electronic key. Remote-controlled vehicle locking systems are to be understood as locking systems equipped with a mechanically operable remote control as well as locking systems equipped with a coil in a so-called "check card" - or transmitter housing, in which the locking operation is started automatically, for example when the door handle is actuated.
Mit Einführung von fernbedienbaren Fahrzeugschließsystemen hat sich der Gebrauch des herkömmlichen mechanischen Schlüssels auf solche in der Regel selten auftretendeWith the introduction of remote-controlled vehicle locking systems, the use of the conventional mechanical key has changed to those that rarely occur
Zustände beschränkt, bei denen das Fernbedienungssystem beispielsweise mangels ausreichender Energieversorgung oder aus anderen Gründen nicht funktioniert. Lediglich für diesen Zweck bedarf es nach wie vor der Mitführung eines mechanischen Schlüssels, der in dieser Funktion als Notfallschlussel bezeichnet wird und im Allgemeinen auch nicht mehr hinsichtlich der Materialauswahl - z. B. mit Kunststoffschaft und -griff - für die sonst üblichen Standzeiten von Fahrzeugschlüsseln ausgelegt ist. Ferner kann häufig beobachtet werden, dass insbesondere nach langjähriger Benutzung eines mechanisch betätigbaren Schließsystems der Benutzer im Zusammenhang mit Schließprozessen wie früher dazu neigt, einen Schlüssel aufzufinden und in der Hand zu positionieren. Im Einzelnen ist ein Schlüsselbehälter mit einem ausschwenkbaren Notfallschlussel bekannt. Der Notfallschlussel ist m einem seitlichen Aufnahmeschacht des Schlüsselbehälters untergebracht und dadurch relativ leicht zugänglich und im Übrigen von außen sichtbar (vgl. DE 39 02 537 C2) .Conditions limited in which the remote control system does not work, for example, due to a lack of sufficient energy supply or for other reasons. Only for this purpose is it still necessary to carry a mechanical key, which in this function is referred to as an emergency key, and generally no longer with regard to the choice of material - e.g. B. with plastic shaft and handle - is designed for the usual downtime of vehicle keys. Furthermore, it can often be observed that, especially after many years of using a mechanically actuable locking system, the user, in connection with locking processes, tends to find a key and position it in the hand. A key container with a swiveling emergency key is known in detail. The emergency key is housed in a side slot in the key container and is therefore relatively easily accessible and otherwise visible from the outside (cf. DE 39 02 537 C2).
Ferner kennt man einen elektronischen Fernbedienungsschlüssel, bei dem das Schlüsselgehäuse die äußere Form eines Kraftfahrzeuges aufweist und der Notfallschlussel mit sei- nem Schlüsselschaft motorseitig oder heckseitig m das Autoprofllgehäuse einsteckbar ist. In diesem Fall bildet der im Schlüsselgehäuse befindliche Notfallschlussel eine Stoßstange. Die Stoßstange wiederum bildet den Schlüssel - köpf bzw. Schlüsselgriff und kragt aus dem Autoprofllge- häuse vor, um bei Benutzungsbedarf unmittelbar zugänglich zu sein und herausgezogen zu werden (vgl. DE 297 22 484 Ul) . Folglich ist nicht auszuschließen, dass der Fahrzeugbenutzer aus Gewohnheit versucht, den so untergebrachten Notfallschlussel zur Fahrzeugöffnung aus dem Schlüsselge- häuse herauszuziehen und zu positionieren. Ferner kann sich der Schlüsselüberstand auch als hinderlich erweisen.Furthermore, an electronic remote control key is known, in which the key housing has the outer shape of a motor vehicle and the emergency key with its key shaft can be inserted into the car profile housing on the motor side or on the rear side. In this case, the emergency key located in the key housing forms a bumper. The bumper in turn forms the key head or key handle and protrudes from the car profile housing in order to be immediately accessible when needed and to be pulled out (cf. DE 297 22 484 Ul). As a result, it cannot be ruled out that the vehicle user will habitually attempt to pull the emergency key that is housed in this way to open the vehicle out of the key housing and position it. The key protrusion can also prove to be a hindrance.
Endlich kennt man einen elektronischen Schlüssel zur Anwendung bei Schließsystemen in Kraftfahrzeugen, mit einem Gehäuse, an dem ein zusätzlicher Schlüsselbart als Notschlüssel für ein mechanisches Schloss angeordnet ist . Der Notschlüssel ist als vom Schlüssel separater Schlüssel ausgebildet. Das Gehäuse enthält eine Aufnahme, in die der Schlüsselbart des Notschlüssels einsteckbar ist . Bei dieser bekannten Ausfuhrungsform besitzt das Gehäuse ein Griffteil für den Benutzer und ein daran angeformtes Steckerteil, während der Notschlüssel als gleichsam vollständiger Schlüssel einen Schlüsselbart und ein Griffstück aufweist, welches aus dem Gehäuse vorkragt. Folglich lässt sich der Notschlüssel nicht vollständig in dem eigentlichen Schlüsselgehäuse unterbringen. Das ist unbefriedigend (vgl. DE 44 44 913 C2) .Finally an electronic key for use in locking systems in motor vehicles is known, with a housing on which an additional key bit is arranged as an emergency key for a mechanical lock. The emergency key is designed as a key separate from the key. The housing contains a receptacle into which the key bit of the emergency key can be inserted. In this known embodiment, the housing has a handle part for the user and a plug part formed thereon, while the emergency key, as a kind of complete key, has a key bit and a handle which protrudes from the housing. Consequently, the Do not fully fit the emergency key in the actual key housing. This is unsatisfactory (cf. DE 44 44 913 C2).
Der Erfindung liegt die Aufgabe zugrunde, einen Fahrzeugschlussel für fernbedienbare Fahrzeugschließsysteme zu schaffen, bei welchem der Notfallschlussel zwar einerseits für den Notfall schnell zugänglich ist, andererseits jedoch eine durch Gewohnheit motivierte Benutzung zumindest erschwert. Darüber hinaus soll verhindert werden, daß der lediglich für den Notfalleinsatz ausgelegte Notfallschlussel durch unnötige Handhabe beschädigt wird.The invention has for its object to provide a vehicle key for remote-controlled vehicle locking systems, in which the emergency key is quickly accessible on the one hand for emergencies, but on the other hand at least complicates use motivated by habit. In addition, the aim is to prevent the emergency key, which is only designed for emergency use, from being damaged by unnecessary handling.
Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung ein Fahrzeugschlussel für fernbedienbare Fahrzeugschließ- systeme, mit einem Schlüsselgehäuse, in dem eine Fernbedienungselektronik und ein mechanischer Notfallschlussel untergebracht sind, wobeiTo achieve this object, the subject of the invention is a vehicle key for remote-controlled vehicle locking systems, with a key housing, in which remote control electronics and a mechanical emergency key are accommodated, wherein
- das Schlüsselgehäuse eine Deckelschale mit einem Tastenfeld und eine geteilte Bodenschale unter Bildung von zwei Bodenschalenteilen aufweist,the key housing has a cover shell with a keypad and a divided base shell to form two base shell parts,
- der Notfallschlussel mit seinem Schlüsselkopf an das eine einen Schlüsselgriff bildende Bodenschalenteil angeschlossen ist und- The emergency key is connected with its key head to the bottom shell part forming a key handle and
- das andere Bodenschalenteil eine Schaftaufnahme für den Schlüsselschaft aufweist.- The other bottom shell part has a shaft holder for the key shaft.
Diese Maßnahmen der Erfindung haben zur Folge, dass der Notfallschlussel vollständig in dem Schlüsselgehäuse untergebracht und folglich in das als Sendergehäuse ausgebildete Schlüsselgehäuse integriert ist. Auf diese Weise ist der Notfallschlussel von außen nicht erkennbar bzw. sichtbar, so dass der Fahrzeug- bzw. Schlüsselbenutzer von vornherein nicht angeregt wird, den Notfallschlussel zur Fahrzeugöffnung zu benutzen, jedenfalls ist eine solche Benutzung erheblich erschwert. Dadurch wird zugleich erreicht, dass der Notfallschlussel, wenn er beispielsweise aus Kunststoff besteht, durch unnötige Handhabe nicht beschädigt wird. Tatsächlich gibt das Schlüsselgehäuse kein Indiz für das Vorhandensein eines Notfallschlüssels innerhalb des Gehäu- ses, welches sich äußerlich lediglich durch sein Design auszeichnet. Die Unterbringung des Notfallschlüssels in dem Schlüsselgehäuse ermöglicht darüber hinaus eine Minimierung der Gehäuseabmessungen, zumal das eine Bodenschalenteil zugleich den Schlüsselgriff bildet, während das andere Bodenschalenteil für die Aufnahme des Schlüsselschaftes sorgt .The result of these measures of the invention is that the emergency key is completely accommodated in the key housing and consequently is integrated in the key housing designed as a transmitter housing. In this way it is Emergency key not recognizable or visible from the outside, so that the vehicle or key user is not encouraged from the start to use the emergency key to open the vehicle, in any case, such use is considerably more difficult. This also ensures that the emergency key, if it is made of plastic, for example, is not damaged by unnecessary handling. In fact, the key housing gives no indication of the presence of an emergency key inside the housing, which is only distinguished by its design on the outside. The accommodation of the emergency key in the key housing also enables the housing dimensions to be minimized, especially since one base shell part also forms the key handle, while the other base shell part takes up the key shaft.
Weitere erfindungswesentliche Merkmale sind im Folgenden aufgeführt. So kann der Schlüsselschaft mittels einer Rast- sitzverbindung lösbar in dem den Schlüsselgriff bildenden Bodenschalenteil befestigt sein. Nach einer anderen Ausführungsform der Erfindung besteht aber auch die Möglichkeit, dass der Schlüsselschaft in dem den Schlüsselgriff bildenden Bodenschalenteil längenverschiebbar gelagert und in eingeschobenem Zustand sowie in Funktionsstellung in demFurther features essential to the invention are listed below. For example, the key shaft can be detachably fastened in the bottom shell part forming the key handle by means of a snap-fit connection. According to another embodiment of the invention, however, there is also the possibility that the key shaft in the bottom shell part forming the key handle is mounted such that it can be displaced in length and in the inserted state and in the functional position in the
Bodenschalenteil verrastbar ist. Durch die Einschiebbarkeit des Notfallschlüssels erfolgt eine weitere Verkürzung der Baulänge des Schlüsselgehäuses und Minimierung seiner Außenabmessungen. - Ferner sieht die Erfindung vor, dass die Bodenschale quer geteilt ist und die beiden Bodenschalenteile miteinander und mit der Deckelschale verrastbar sind. Bevorzugt sind die Deckelschale und das den Schlüsselschaft aufnehmende Bodenschalenteil miteinander durch Ultraschallschweißen oder Verkleben verbunden. Das den Schlüsselgriff bildende Bodenschalenteil ist dann, auch zum einfachen Austausch der Batterie, lediglich durch Verrasten und folglich lösbar mit dem den Schlüsselschaft aufnehmenden Bodenschalenteil 3 verbunden. Im Übrigen können die Deckelschale und die Bodenschale und folglich das Schlüsselgehäuse einen Zündschlüsselstumpf zum Einleiten des Montageprozesses aufweisen, wobei bei der Schlüsseldrehung im Zündschloß mit dem Zündschlüsselstumpf in der Regel ebenfalls in dem Sendergehäuse angeordnete Transponder (Weg- fahrsperre) abgelesen wird. Endlich sieht die Erfindung vor, dass der Notfallschlussel unterhalb der Fernbedienungselektronik in der Bodenschale untergebracht ist und der Schlüsselkopf eine Batterie gegen eine Elektronikplatine der Fernbedienungselektronik unter Kontaktherstellung andrückt, wenn sich also der Notfallschlussel in dem Schlüsselgehäuse befindet. Die Fernbedienungselektronik weist neben der Elektronikplatine in herkömmlicher Weise einen Sender und Empfänger auf, einen Controller und integrierten Transponder für eine Wegfahrsperre, oder alter- nativ auch eine Spule oder einen Transponder für dasBottom shell part is lockable. The insertability of the emergency key further shortens the overall length of the key housing and minimizes its external dimensions. - Furthermore, the invention provides that the bottom shell is divided transversely and the two bottom shell parts can be locked together and with the cover shell. The cover shell and the base shell part receiving the key shaft are preferably connected to one another by ultrasonic welding or gluing. That the The bottom grip part forming the key grip is then connected to the bottom shell part 3 receiving the key shaft only by latching and consequently releasably, also for easy replacement of the battery. In addition, the cover shell and the base shell, and consequently the key housing, can have an ignition key stump for initiating the assembly process, with transponders (immobilizer) generally also being read in the transmitter housing when the key is turned in the ignition lock with the ignition key stump. Finally, the invention provides that the emergency key is accommodated below the remote control electronics in the base shell and the key head presses a battery against an electronic circuit board of the remote control electronics while making contact, that is when the emergency key is located in the key housing. In addition to the electronic circuit board, the remote control electronics conventionally have a transmitter and receiver, a controller and integrated transponder for an immobilizer, or alternatively also a coil or a transponder for the
