Abstract

The invention relates to an electronic key (10), in which coded signals (20) are transmitted and optionally received. In order to achieve this, it is necessary to provide suitable electronic components which are supplied with electric energy by a current reservoir in the housing interior (21). A mass (22) is kinetically mounted (24) in the housing interior (21), in order to ensure that the electronic key (10) is continuously operational. The kinetic energy (23) of said mass (22) which is generated when the key is moved, is converted into electric energy by an electric generator (26), provided in the housing interior (21). The electric energy is subsequently used to continuously recharge the current reservoir.

Description

Elektronischer Schlüssel, insbesondere für Fahrzeuge Electronic key, especially for vehicles
Die Erfindung richtet sich auf einen elektronischen Schlüssel der im Oberbegriff des Anspruches 1 angegebenen Art. Zum Betrieb der elektronischen Bauteile verwendet man in der Regel elektrische Batterien in Form von sogenannten Knopfzellen. Nach einiger Gebrauchszeit entleeren sich die Batterien. Es müssen daher Vorkehrungen getroffen werden, um die Batterien bequem ausbauen, neue Batterien wieder einbauen und zuverlässig kontaktieren zu können. Dafür muss ein geeigneter Platz im Schlüsselgehäuse reserviert sein. Das ist aufwendig. Das Auswechseln der Batterie ist mühevoll und erfordert eine eingehende Belehrung des Schlüsselbesitzers, der dazu nicht immer bereit ist.The invention relates to an electronic key of the type specified in the preamble of claim 1. Electric batteries in the form of so-called button cells are generally used to operate the electronic components. The batteries will empty after a period of use. Precautions must therefore be taken to be able to easily remove the batteries, reinstall new batteries and be able to contact them reliably. A suitable space in the key housing must be reserved for this. It is expensive. Replacing the battery is tedious and requires detailed instruction from the key owner, who is not always ready to do so.
Man kann anstelle von solchen Einweg-Batterien auch Akkumulatoren als Stromspeicher für die elektrische Energie im Schlüsselgehäuse verwenden. Es sind aber zum regelmäßigen Aufladen eines solchen Stromspeichers Anschlüsse im Schlüsselgehäuse erforderlich, deren Anordnung wegen der sehr begrenzten Gehäuseoberfläche problematisch ist. Außerdem sind Anzeigemittel für den Ladezustand des Stromspeichers erforderlich, wenn man von einer plötzlichen Entleerung des Stromspeichers nicht überrascht werden will. Auch das erfordert an der Gehäuseoberfläche Platz. Vor allem ist aber während des Ladevorgangs der Schlüssel nicht nutzbar. Der Schlüsselinhaber muss daher die Pausen zwischen der Benutzung des Schlüssels nutzen und die Ladetätigkeit gut einplanen. Das wird als störend empfunden. Für den Betrieb elektrischer Kleingeräte (DE 196 20 880 AI) ist es bekannt, die zum bestimmungsgemäßen Gebrauch des Geräts erforderliche manuelle Betätigung eines Funktionsauslöseelements dazu zu verwenden, um daraus eine elektrische Energie zu gewinnen. Als Kleingerät verwendete man dabei auch einen mechanischen Schlüssel mit integrierter Infrarot-Sendeeinrichtung. Weil zur Gewinnung der elektrischen Energie ein entsprechendes, mechanisches Energieäquivalent aufgebracht werden muss, ist der Betätiger bei diesem Kleingerät schwergängig. Dies wirkt sich unangenehm bei der Handhabung aus.Instead of such disposable batteries, it is also possible to use accumulators as electricity stores for the electrical energy in the key housing. However, connections in the key housing are required for the regular charging of such a power store, the arrangement of which is problematic because of the very limited housing surface. In addition, display means for the state of charge of the power storage are required if one does not want to be surprised by a sudden draining of the power storage. This also requires space on the housing surface. Above all, the key cannot be used during the loading process. The key holder must therefore use the breaks between using the key and plan the loading activity well. This is perceived as annoying. For the operation of small electrical devices (DE 196 20 880 AI) it is known to use the manual actuation of a function trigger element required for the intended use of the device in order to obtain electrical energy therefrom. A mechanical key with an integrated infrared transmitter was also used as the small device. Because a corresponding mechanical energy equivalent has to be applied to obtain the electrical energy, the actuator on this small device is stiff. This has an unpleasant handling effect.
Bei einem Türschloss mit einem manuell mittels eines Schlüssels schließbaren Schlossriegel (DE 32 08 818 C2) verwendete man einen elektrischen Antrieb für den Schlossriegel. Der elektrische Antrieb war an einen netzunabhängigen Speicher oder Generator angeschlossen. Die bestimmungsgemäße Betätigung des Schlosses beim Öffnen und Schließen wurde dazu genutzt, um den Generator anzutreiben. Die Betätigung zur Gewinnung elektrischer Energie konnte in einem Fall vom Türgriff ausgehen, der mit dem Generator gekuppelt war. In einem anderen Fall war das Antriebsritzel des dynamischen Generators mit einer Zahnstange eines im Schloss längsverschieblichen Schlüssels verbunden, der beim Ein- bzw. Ausstecken über den Generator elektrische Energie erzeugte.In the case of a door lock with a lock bolt which can be locked manually by means of a key (DE 32 08 818 C2), an electric drive was used for the lock bolt. The electric drive was connected to a network-independent memory or generator. The intended operation of the lock when opening and closing was used to drive the generator. In one case, the operation to generate electrical energy could come from the door handle, which was coupled to the generator. In another case, the drive pinion of the dynamic generator was connected to a toothed rack of a key which can be moved longitudinally in the lock and which generated electrical energy when the plug was inserted or removed.
Schließlich ist es bekannt (DE 197 21 001 Cl) bei einem elektronischen Gerät einen längsverschieblichen Schieber oder einen drehbaren Rotationskörper vorzusehen, der, um elektrische Energie für das Gerät zu gewinnen, mit der Hand oder mit den Fingern bewegt werden musste. Die elektrische Energie wurde hier zwar auf mechanischem Wege erzeugt, doch musste dazu der Schieber bzw. der Rotationskörper gezielt manuell angetrieben werden. Das war mühsam und zeitaufwendig. Wurde es vergessen lag keine nutzbare elektrische Energie vor, weshalb der Betrieb des elektronischen Geräts ausfiel. Der Schieber bzw. der Rotationskörper erfordert einen großen Flächenbereich auf der Gehäuseaußenseite, um für die Hand zu Antriebszwecken gut zugänglich zu sein. Die Anwendung auf elektronische Schlösser war zwar vorgesehen, ist aber für elektronische Schlüssel ungeeignet. Es ist bei Armbanduhren bekannt, dreh- oder schwenkbewegliche Pendel im Uhrengehäuse vorzusehen, welche für die mechanische Energieversorgung des Uhrwerks sorgen. Es liegt aber nicht nahe diese Uhrenmechanik auf elektronische Schlüssel zu übertragen, die, abgesehen von einem eventuellen mechanischen Notschlüssel, keine mechanische Funktionen haben und auf einen elektrischen Stromspeicher angewiesen sind.Finally, it is known (DE 197 21 001 Cl) to provide a longitudinally displaceable slide or a rotatable rotary body in an electronic device which had to be moved by hand or with the fingers in order to obtain electrical energy for the device. The electrical energy was generated here mechanically, but for this purpose the slide or the rotating body had to be driven manually. It was tedious and time consuming. If it was forgotten, there was no usable electrical energy, which is why the operation of the electronic device failed. The slide or the rotating body requires a large surface area on the outside of the housing in order to be easily accessible for driving purposes. The application to electronic locks was intended, but is unsuitable for electronic keys. It is known in wristwatches to provide rotatable or pivotable pendulums in the watch case, which provide the mechanical energy supply for the clockwork. However, it is not obvious to transfer this watch mechanism to electronic keys, which, apart from a possible mechanical emergency key, have no mechanical functions and are dependent on an electrical power store.
Der Erfindung liegt die Aufgabe zugrunde einen preiswerten elektronischen Schlüssel der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, dessen Betriebsbereitschaft sich durch einen besonders bequemen Service auszeichnet. Dies wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angeführten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to develop an inexpensive electronic key of the type mentioned in the preamble of claim 1, the operational readiness of which is characterized by a particularly convenient service. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special significance.
Die Erfindung hat erkannt, dass der elektronische Schlüssel normalerweise Bewegungen ausgesetzt ist, die sich in Beschleunigungen und Verzögerungen des Schlüssels auswirken. Dadurch werden unvermeidlich dauernd mechanische Kräfte auf den Schlüssel ausgeübt, die zur Gewinnung von mechanischer Energie genutzt werden können. Dies tritt nicht nur in einer Ruhephase des Schlüssels ein, wenn der Schlüssel vom Besitzer in der Hosentasche od. dgl. getragen wird und der Schlüsselbesitzer sich bewegt, sondern auch während der Arbeitsphase des Schlüssels, wenn der Schlüssel im Schloss steckt und das Fahrzeug sich beschleunigend oder verzögernd bewegt.The invention has recognized that the electronic key is normally subjected to movements which result in accelerations and decelerations of the key. As a result, mechanical forces are inevitably continuously exerted on the key, which can be used to generate mechanical energy. This occurs not only when the key is at rest when the key is carried in the pocket or the like by the owner and the key owner is moving, but also during the key's working phase when the key is in the lock and the vehicle accelerates or moved with delay.
Ordnet man nun eine Masse im Schlüsselgehäuse beweglich an, so kann die dort anfallende mechanische Energie von einem elektrischen Generator in elektrische Energie gewandelt werden. Diese elektrische Energie kann dann zum Aufladen des im Schlossgehäuse befindlichen Stromspeichers genutzt werden.If you now arrange a mass to be movable in the key housing, the mechanical energy generated there can be converted into electrical energy by an electrical generator. This electrical energy can then be used to charge the power storage located in the lock housing.
Bei der Erfindung ist nicht nur der Stromspeicher sondern auch die Aufladeeinrichtung und die Energieerzeugung im Inneren des Schlüsselgehäuses integriert. Es brauchen daher an der Gehäuseoberfläche keinen besonderen Maßnahmen zur Zugänglichkeit ins Schlüsselinnere oder zur Energieversorgung von außen erfolgen. Der Schlüsselinhaber braucht sich um die Energieversorgung des elektronischen Schlüssels überhaupt nicht mehr zu kümmern; das Aufladen des Schlüssels erfolgt automatisch bei jeder Schlüsselbewegung, also sowohl in der Ruhe- als auch in der Gebrauchsphase des Schlüssels. Der erfindungsgemäße Schlüssel ist stets betriebsbereit.In the invention, not only the power storage but also the charging device and the energy generation are integrated in the interior of the key housing. There is therefore no need for any special measures on the housing surface to access the interior of the key or to supply energy to done outside. The key holder no longer has to worry about the energy supply for the electronic key; The key is automatically loaded with every key movement, i.e. both in the idle and in the use phase of the key. The key according to the invention is always ready for use.

Der elektronische Schlüssel 10 umfasst ein Schlüsselgehäuse 11 dessen eines Ende 12 mit einem geeigneten Einsteckprofil 12 versehen ist. Diesem elektronischen Schlüssel ist ein komplementäres elektronisches Schloss zugeordnet, das eine geeignete Aufnahme für das Einsteckprofil 12 aufweist. Im Schlüsselinneren sind verschiedenste elektronische Bauteile 13 vorgesehen, die in definierter Weise miteinander geschaltet sind, z.B. über Leiterbahnen einer sogenannten elektrischen Leiterplatte. Die elektronischen Bauteile 13 haben verschiedene Funktionen zu erfüllen. Außer der Kommunikation mit dem zugehörigen Schloss gehört dazu auch das Aussenden oder Empfangen von codierten Signalen 20, z.B. in Form einer elektromagnetischen hochfrequenten Strahlung. Dazu ist ein geeigneter Sender 14 im Schlüsselgehäuse integriert, zweckmäßigerweise am Stirnende 15 des Einsteckabschnitts 12.The electronic key 10 comprises a key housing 11, one end 12 of which is provided with a suitable insertion profile 12. This electronic key is assigned a complementary electronic lock, which has a suitable receptacle for the insertion profile 12. Various electronic components 13 are provided in the interior of the key, which are connected to one another in a defined manner, e.g. via conductor tracks of a so-called electrical circuit board. The electronic components 13 have different functions to perform. In addition to communicating with the associated lock, this also includes sending or receiving coded signals 20, e.g. in the form of electromagnetic high-frequency radiation. For this purpose, a suitable transmitter 14 is integrated in the key housing, expediently at the front end 15 of the insertion section 12.
Zur Energieversorgung der Schaltung und ihrer Bauteile 13 dient ein elektrischer Stromspeicher 16. Die elektrischen Bauteile 13 können durch einen Schalter 17 wirksam gesetzt werden. Der Schalter 17 wird von einem Betätiger 18, z.B. einem Taster, ein- und/oder ausgeschaltet. Das ist durch einen Betätigungspfeil 19 im Schema von Fig. 2 veranschaulicht. Dieser Betätiger 18 ist durch eine geeignete Profilierung eines Gehäusebereichs in die Gehäuseschale integriert.An electrical power store 16 is used to supply energy to the circuit and its components 13. The electrical components 13 can be switched 17 be put into effect. The switch 17 is switched on and / or off by an actuator 18, for example a button. This is illustrated by an operating arrow 19 in the diagram in FIG. 2. This actuator 18 is integrated into the housing shell by suitable profiling of a housing area.
Im Gehäuseinneren 21 ist eine Masse 22 beweglich gelagert, wie durch den Bewegungspfeil 23 veranschaulicht ist. Im vorliegenden Fall ist diese Masse 22 an einem Lagerzapfen 24 frei drehgelagert, weshalb hier ein Pendel 25 vorliegt. Diese Pendelbewegung 25 wird als mechanische Energie einem zugeordneten Generator 26 zugeführt, der elektrische Energie erzeugt und diese über die in Fig. 2 verdeutlichte elektrische Verbindung 27 zum Aufladen des Stromspeichers 16 nutzt.A mass 22 is movably supported in the housing interior 21, as illustrated by the movement arrow 23. In the present case, this mass 22 is freely rotatably supported on a bearing journal 24, which is why there is a pendulum 25 here. This pendulum movement 25 is supplied as mechanical energy to an associated generator 26, which generates electrical energy and uses it to charge the energy store 16 via the electrical connection 27 illustrated in FIG. 2.
Die rotatorische Energie eines Pendels 25 ist zwar besonders geeignet, doch wäre es auch möglich, die mechanische Energie durch eine translatorische Bewegung einer Masse 22 zu erzeugen. Die mechanische Energie kann in beliebiger Weise durch bewegliche Massen oder Flüssigkeiten im Inneren des Schlüsselgehäuses erzeugt werden. Entscheidend ist, dass die bei der Benutzung und Nichtbenutzung des Schlüssels anfallenden mechanischen Bewegungen in elektrische Energie umgewandelt werden, die zur Versorgung der elektronischen Bauteile beim bestimmungsgemäßen Gebrauch des elektronischen Schlüssels dient. The rotational energy of a pendulum 25 is particularly suitable, but it would also be possible to generate the mechanical energy by translatory movement of a mass 22. The mechanical energy can be generated in any way by moving masses or liquids inside the key housing. It is crucial that the mechanical movements occurring when the key is used and not used are converted into electrical energy, which is used to supply the electronic components when the electronic key is used as intended.
