Description

Die vorliegende Erfindung betrifft einen Kraftfahrzeugschlüssel, umfassend einen Schlüsselkörper und eine Antenne.The present invention relates to a motor vehicle key comprising a key body and an antenna.

Es ist bekannt, Kraftfahrzeugschlüssel alternativ oder zusätzlich zu einem herkömmlichen Schlüsselbart, der zum mechanischen Öffnen eines Türschlosses und Betätigen eines Zündschlosses des Kraftfahrzeugs dient, mit elektrischen Funktionen auszustatten, beispielsweise zum Ansteuern einer elektrischen Wegfahrsperre oder einer Zentralverriegelung oder zum kontaktlosen Öffnen und Starten des Kraftfahrzeugs per Funk. Außerdem ist es bekannt, Kraftfahrzeugschlüssel mit einer elektronischen Bezahlfunktion via Funk auszustatten.It is known motor vehicle key alternatively or in addition to a conventional key bit, which serves for the mechanical opening of a door lock and operating an ignition lock of the motor vehicle to equip with electrical functions, for example for driving an electric immobilizer or a central locking or contactless opening and starting of the motor vehicle by Wireless. It is also known to equip motor vehicle key with an electronic payment function via radio.

Hinsichtlich der oben genannten Funktionalitäten müssen gewisse Standards erfüllt werden, insbesondere was die verwendeten Funkfrequenzen betrifft. Dabei tritt das Problem auf, dass bei Antennen bestimmter Frequenzen Störungen in der Datenübertragung auftreten.With regard to the above-mentioned functionalities, certain standards must be met, in particular as regards the radio frequencies used. The problem arises that in antennas of certain frequencies disturbances in the data transmission occur.

Aufgabe der vorliegenden Erfindung ist es daher, einen Kraftfahrzeugsschlüssel bereitzustellen, der eine störungsarme Datenkommunikation per Funk erlaubt.Object of the present invention is therefore to provide a motor vehicle key that allows low-interference data communication by radio.

Diese Aufgabe wird durch einen Kraftfahrzeugsschlüssel gemäß den Merkmalen des unabhängigen Anspruchs gelöst. In davon abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung angegeben.This object is achieved by a motor vehicle key according to the features of the independent claim. In dependent claims advantageous embodiments and developments of the invention are given.

Bei dem erfindungsgemäßen Kraftfahrzeugschlüssel ist zumindest ein Antennenabschnitt der Antenne derart zwischen einer Internposition und einer Externposition bewegbar an oder in dem Schlüsselkörper angeordnet, dass einerseits die Antennenfläche der Antenne in der Internposition nicht größer ist als die Fläche des Schlüsselkörpers in seiner Hauptebene. Als Hauptebene wird dabei diejenige der Ebenen bezeichnet, zu denen der Schlüsselkörper im Wesentlichen symmetrisch ist, in der der Schlüsselkörper die maximale Ausdehnung bzw. Fläche aufweist, z.B. bei einer im Wesentlichen flächigen Form des Schlüsselkörpers die die entsprechende Fläche aufspannende Ebene. Zusätzlich ist die Antenne gleichzeitig derart bewegbar an oder in dem Schlüsselkörper angeordnet, dass andererseits die Antennenfläche der Antenne in der Externposition größer ist als in der Internposition.In the motor vehicle key according to the invention, at least one antenna section of the antenna is movably arranged between an internal position and an external position on or in the key body such that on the one hand the antenna surface of the antenna in the internal position is not larger than the surface of the key body in its main plane. The main plane is that of the planes to which the key body is substantially symmetrical, in which the key body has the maximum extent, e.g. in a substantially flat shape of the key body, the plane spanning the corresponding surface. In addition, the antenna is simultaneously movable on or in the key body, on the other hand, the antenna surface of the antenna in the external position is greater than in the internal position.

Folglich kann ein Kraftfahrzeugschlüssel bereitgestellt werden, der, wenn sich der Antennenabschnitt in der Internposition befindet, in der Hauptebene ausreichend kompakt ist, d.h. im wesentlichen genauso kompakt wie herkömmliche Kraftfahrzeugschlüssel. Derselbe Schlüssel besitzt, wenn sich die Antennenfläche in der Externposition befindet, jedoch eine besonders große Antennenfläche, die ausreichend ist, die Qualität einer Datenübertragung per Funk wesentlich zu verbessern.Thus, an automobile key can be provided which, when the antenna section is in the home position, is sufficiently compact in the main plane, i. essentially as compact as conventional motor vehicle keys. However, the same key has, when the antenna surface is in the external position, a particularly large antenna area sufficient to substantially improve the quality of data transmission by radio.

Der oder die Antennenabschnitte werden in der Internposition idealerweise platzsparend am oder im Schlüsselkörper angeordnet. Gemäß einer bevorzugten Ausführungsform sind dementsprechend zumindest zwei der bewegbaren Antennenabschnitte an dem Schlüsselkörper angeordnet und derart ausgestaltet, dass sie sich in der Internposition nicht überlappen, so dass sie in dem Schlüsselkörper in einer Ebene liegen können und dann möglichst wenig Platz einnehmen. Alternativ hierzu können die Antennenabschnitte auch derart an dem Schlüsselkörper angeordnet und ausgestaltet sein, dass sie sich in der Internposition überwiegend überlappen, z.B. mit zumindest 70% oder zumindest 50% der Fläche einer der betreffenden Antennenabschnitte. Hierbei ergibt sich eine möglichst große Antennenfläche in der Externposition.The antenna sections or the antenna sections are ideally arranged in the internal position to save space on or in the key body. Accordingly, according to a preferred embodiment, at least two of the movable antenna sections are arranged on the key body and designed such that they do not overlap in the internal position, so that they can lie in the key body in a plane and then occupy as little space as possible. Alternatively, the antenna sections also be arranged and configured on the key body such that they predominantly overlap in the internal position, eg with at least 70% or at least 50% of the area of one of the relevant antenna sections. This results in the largest possible antenna area in the external position.

Gemäß einer weiteren bevorzugten Ausführungsform ist der zumindest eine Antennenabschnitt um eine senkrecht zu dessen Antennenfläche verlaufende Achse zwischen der Internposition und der Externposition schwenkbar angeordnet.According to a further preferred embodiment, the at least one antenna section is arranged pivotable about an axis extending perpendicularly to its antenna surface between the internal position and the external position.

Insbesondere, jedoch nicht ausschließlich bei dieser Ausführungsform sind vorzugsweise zumindest zwei der Antenennabschnitte vorhanden, die um durch im Wesentlichen diagonal gegenüberliegende Punkte des Schlüsselkörpers verlaufende Achsen schwenkbar angeordnet sind und im Wesentlichen dreiecksförmig sind. Dadurch können diese platzsparend im oder am Schlüsselkörper untergebracht werden, insbesondere derart, dass sie sich in der Internposition nicht überlappen und so platzsparend in einer Ebene zu liegen kommen.In particular, but not exclusively in this embodiment, preferably at least two of the antenna sections are provided, which are arranged pivotable about substantially diagonally opposite points of the key body extending axes and are substantially triangular. As a result, these can be accommodated in a space-saving manner in or on the key body, in particular in such a way that they do not overlap in the internal position and thus come to lie in a plane in a space-saving manner.

Alternativ oder zusätzlich kann der zumindest eine Antennenabschnitt auch um eine in der oder parallel zur Antennenfläche verlaufende Achse schwenkbar an dem Schlüsselkörper angeordnet sein, z.B. derart, dass sich die Achse auch parallel zu der Hauptebene des Schlüsselkörpers erstreckt. Dies erlaubt ein Schwenken des Antennenabschnitts von der Intern- in die Externposition, ähnlich wie dies vom Aufklappen eines Mobiltelefons bekannt ist.Alternatively or additionally, the at least one antenna section can also be arranged pivotably on the key body about an axis running in or parallel to the antenna surface, for example in such a way that the axis also extends parallel to the main plane of the key body. This allows pivoting of the antenna section from the internal to the external position, similar to the opening of a mobile phone is known.

Die erfindungsgemäße Vergrößerung der Antennenfläche ist für eine störungsfreie Datenkommunikation via Funk besonders vorteilhaft, wenn der Schlüssel weitere Komponenten umfasst, die die Datenkommunikation via Funk beeinträchtigen. Dies ist z.B. dann der Fall, wenn neben der genannten Antenne noch eine oder mehrere Schlüsselantennen vorhanden sind, insbesondere wenn neben einer auf eine Frequenz von 13,56 MHz abgestimmten Antenne (üblicherweise für elektronisches Bezahlen, Gebäudezugänge und Authentifizierung verwendete Funkfrequenz) noch eine auf eine Frequenz von 128 KHz abgestimmte Antenne (üblicherweise zur Kommunikation mit einem Board-Computer eines Kraftfahrzeugs verwendete Frequenz) und/oder noch eine auf eine Frequenz von 433 MHz abgestimmte Antenne (üblicherweise zur Ansteuerung einer Zentralverriegelung des Fahrzeugs verwendete Frequenz) in dem Schlüssel integriert ist.The enlargement of the antenna surface according to the invention is particularly advantageous for interference-free data communication via radio if the key comprises further components which impair the data communication via radio. This is e.g. then the case, if in addition to the said antenna still one or more key antennas are present, especially if in addition to an antenna tuned to a frequency of 13.56 MHz (usually used for electronic payment, building access and authentication radio frequency) one more to a frequency of 128 KHz tuned antenna (commonly used for communication with a board computer of a motor vehicle) and / or yet one tuned to a frequency of 433 MHz antenna (commonly used for controlling a central locking of the vehicle frequency) in the key is integrated.

Dementsprechend umfasst der Kraftfahrzeugschlüssel gemäß einer weiteren bevorzugten Ausführungsform zusätzlich zu der genannten Antenne eine Schlüsselkommunikationseinheit und eine Schlüsselantenne zur Drahtlos-Kommunikation mit einem Kraftfahrzeug, die vorzugsweise auf eine Frequenz von 128 KHz und/oder 433 MHz abgestimmt ist. Außerdem ist die Antenne mit dem bewegbaren Antennenabschnitt vorzugsweise (in der Internposition und/oder insbesondere der Externposition) auf eine Frequenz von 13,56 MHz abgestimmt. In diesem Frequenzbereich kann bei ausreichender Antennengrösse die Energieversorgung für den Betrieb des Transponders aus dem Feld gewonnen werden, d.h. die Vergrösserung der effektiven Antennenfläche wird die Energieversorgung deutlich erhöhen. Selbstverständlich kann natürlich grundsätzlich auch die Antenne mit dem bewegbaren Antennenabschnitt auf eine Frequenz von 128 KHz und/ oder 433 MHz oder eine beliebige sonstige Frequenz abgestimmt sein und gegebenenfalls mittels einer Schlüsselkommunikationseinheit zur Drahtlos-Kommunikation mit dem Kraftfahrzeug genutzt werden.Accordingly, according to a further preferred embodiment, the motor vehicle key comprises, in addition to said antenna, a key communication unit and a key antenna for wireless communication with a motor vehicle, which is preferably tuned to a frequency of 128 KHz and / or 433 MHz. In addition, the antenna with the movable antenna section is preferably tuned (in the internal position and / or in particular the external position) to a frequency of 13.56 MHz. In this frequency range, the power supply for the operation of the transponder can be obtained from the field with sufficient antenna size, ie, the increase of the effective antenna surface will significantly increase the power supply. Of course, of course, in principle, the antenna with the movable antenna section to a frequency of 128 KHz and / or 433 MHz or any other frequency be tuned and optionally be used by a key communication unit for wireless communication with the motor vehicle.

Gemäß einer bevorzugten Ausführungsform umfasst der Schlüssel zusätzlich eine Datenträgereinheit, die zur Drahtlos-Kommunikation mittels der Antenne eingerichtet ist.According to a preferred embodiment, the key additionally comprises a data carrier unit which is set up for wireless communication by means of the antenna.

Die Datenträgereinheit und der Schlüsselkörper sind bevorzugt derart ausgestaltet, dass die Datenträgereinheit manuell von dem Schlüsselkörper entfernt und an dem Schlüsselkörper angeordnet werden kann. Dementsprechend kann eine technisch veraltete Datenträgereinheit auf einfache Art und Weise ersetzt werden, ohne den gesamten Schlüssel ersetzen zu müssen.The data carrier unit and the key body are preferably designed such that the data carrier unit can be manually removed from the key body and arranged on the key body. Accordingly, a technically obsolete data carrier unit can be easily replaced without having to replace the entire key.

Die Datenträgereinheit ist vorzugsweise eingerichtet, eine drahtlose elektronische Bezahlung, insbesondere im öffentlichen Nahverkehr, ein elektronisches Kundenbindungsprogramm, einen Gebäudezugang und/oder eine Authentifizierung zu ermöglichen.The data carrier unit is preferably set up to enable wireless electronic payment, in particular in public transport, an electronic customer loyalty program, building access and / or authentication.

Gemäß einer bevorzugten Ausführungsform ist die Datenträgereinheit zwischen einer Schutzposition, in der eine Kontakt-Schnittstelle der Datenträgereinheit durch den Schlüsselkörper vor mechanischer Beschädigung geschützt ist, und einer Kontaktierungsposition, in der die Kontakt-Schnittstelle kontaktierbar ist, an dem Schlüsselkörper bewegbar angeordnet. Die Kontakt-Schnittstelle kann z.B. dazu genutzt werden, eine neue Software auf die Datenträgereinheit aufzuspielen, darauf gespeicherte Daten auszulesen oder dergleichen.According to a preferred embodiment, the data carrier unit between a protective position in which a contact interface of the data carrier unit is protected by the key body from mechanical damage, and a contacting position in which the contact interface is contacted, arranged on the key body movable. The contact interface may e.g. be used to play a new software on the disk unit to read stored data or the like.

Vorzugsweise ist der Kraftfahrzeugschlüssel zudem derart ausgestaltet, dass eine Drahtlos-Kommunikation mittels der Datenträgereinheit gesperrt ist, sofern sich die Datenträgereinheit in der Schutzposition befindet, z.B. um ein unbefugtes Ansprechen einer Bezahlfunktion sicher zu verhindern.Preferably, the motor vehicle key is also configured such that a wireless communication is blocked by means of the data carrier unit, if the data carrier unit is in the protection position, eg to reliably prevent an unauthorized activation of a payment function.

Zu diesem Zweck kann z.B. der Kraftfahrzeugschlüssel derart ausgestaltet sein, dass in der Kontaktposition zwischen der Datenträgereinheit und der Antenne ein elektrischer Kontakt besteht, der in der Schutzposition unterbrochen ist. Alternativ oder zusätzlich kann der Kraftfahrzeugschlüssel derart ausgestaltet sein, dass in der Schutzposition Leiterbahnen der Antenne durch die Datenträgereinheit kurzgeschlossen sind.For this purpose, e.g. the motor vehicle key is configured such that in the contact position between the data carrier unit and the antenna there is an electrical contact which is interrupted in the protective position. Alternatively or additionally, the motor vehicle key can be designed such that, in the protective position, conductor tracks of the antenna are short-circuited by the data carrier unit.

In Analogie dazu kann der Kraftfahrzeugschlüssel alternativ oder zusätzlich derart ausgestaltet sein, dass eine Drahtlos-Kommunikation mittels der Datenträgereinheit gesperrt ist, sofern sich der Antennenabschnitt in der Internposition befindet, z.B. mittels geeigneter Schaltkontakte.By analogy with this, the motor vehicle key may alternatively or additionally be configured such that a wireless communication is blocked by means of the data carrier unit if the antenna section is in the internal position, e.g. by means of suitable switching contacts.

Gemäß einer weiteren bevorzugten Ausführungsform ist der Schlüsselkörper derart ausgestaltet, dass ein Bewegen des Antennenabschnitts von der Internposition in die Externposition gesperrt ist, sofern sich die Datenträgereinheit in der Schutzposition befindet. Dadurch kann z.B. dem Benutzer des Schlüssels signalisiert werden, dass er die Datenträgereinheit vor deren Verwendung zur funkbasierten Datenkommunikation mittels der Datenträgereinheit in die Kontaktierungsposition bringen muss, was insbesondere bei Kombination mit dem zuvor beschriebenen Sperren der Drahtlos-Kommunikation der in der Schutzposition befindlichen Datenträgereinheit von Vorteil ist.According to a further preferred embodiment, the key body is configured such that movement of the antenna section from the internal position to the external position is blocked if the data carrier unit is in the protection position. Thereby, e.g. be signaled to the user of the key that he must bring the data carrier unit before use for radio-based data communication by means of the data carrier unit in the contacting position, which is particularly advantageous when combined with the previously described locking the wireless communication of the located in the protective position data carrier unit.

Alternativ oder zusätzlich ist der Schlüsselkörper derart ausgestaltet, dass bei Bewegen der Datenträgereinheit von der Schutzposition in die Kontaktierungsposition der Antennenabschnitt von der Internposition in die Externposition oder in Richtung der Externposition bewegt wird.Alternatively or additionally, the key body is designed such that upon movement of the data carrier unit from the protective position into the contacting position the antenna section is moved from the internal position to the external position or to the external position.

Für die drahtlose Kommunikation ist jedes geeignete Verfahren möglich. Insbesondere kann der sogenannte Near Field Communication (NFC) Standard vorteilhaft verwendet werden. Der NFC-Standard hat drei sogenannte Modi, nämlich als Karte, bei dem auf einen Datenträger zugegriffen wird, um einen Speicher zu lesen, als ein Lesegerät, um Daten aus einem Speicher zu lesen, oder im Peer-to-Peer-Modus. Somit kann beispielsweise der z.B. an einen PC angeschlossene Schlüssel auch als ein NFC-Leser verwendet werden.For wireless communication, any suitable method is possible. In particular, the so-called Near Field Communication (NFC) standard can be advantageously used. The NFC standard has three so-called modes, a card that accesses a volume to read a memory, a reader to read data from a memory, or peer-to-peer mode. Thus, for example, the e.g. Keys connected to a PC can also be used as an NFC reader.

Die Vergrösserung der effektiven Antennenfläche ermöglicht somit vor allem eine Leistungsverbesserung im Modus als Karte (sogenannter Being Card Modus). Falls sehr kleine Bauformen verwendet werden, ist eine Abkopplung von möglichen anderen Antennen auf dem Schlüssel und der Betrieb als Lesegerät möglich.The enlargement of the effective antenna area thus makes it possible, above all, to improve the performance in the mode as a card (so-called "Being Card Mode"). If very small designs are used, a decoupling of possible other antennas on the key and the operation as a reader is possible.

Im weiteren Sinn ist das beschriebene Konzept auch für andere kleine Formfaktoren, z.B. kleiner MP-3 Player, Schlüsselanhänger, etc., verwendbar, um diese mit einer Kontaktlos-Funktionalität auszustatten.In a broader sense, the described concept is also applicable to other small form factors, e.g. small MP-3 player, keychain, etc., usable to equip them with contactless functionality.

Die Figuren 1a und 1b zeigen Schnittdarstellungen eines Kraftfahrzeugsschlüssels 10 gemäß einer ersten Ausführungsform und die Figuren 1b und 1c Ansichten dieses Kraftfahrzeugsschlüssels 10 von oben. Der Kraftfahrzeugschlüssel 10 besitzt einen Schlüsselkörper 20 und ist mit einer Antenne 40 mit Antennenwindungen (Leiterbahnen) 42 ausgestattet. Die Antenne 40 umfasst einen Antennenabschnitt 41, der von der in den Figuren 1a und 1c dargestellten Internposition in die in den Figuren 1b und 1d dargestellte Externposition und zurück schwenkbar ist. Hierzu ist er über eine parallel zu der Hauptebene des Schlüsselkörpers 20 (und der durch die Antennenwindungen 42 aufgespannten zur Hauptebene parallelen Antennenfläche) verlaufende Schwenkachse 22 (z.B. ein Gelenk) an dem Schlüsselkörper 20 angeordnet.Further features and advantages of the invention will become apparent from the following description of embodiments of the invention and other alternative embodiments in conjunction with the drawings, which show schematically

The FIGS. 1a and 1b show sectional views of a motor vehicle key 10 according to a first embodiment and the Figures 1b and 1c Views of this motor vehicle key 10 from above. The motor vehicle key 10 has a key body 20 and is equipped with an antenna 40 with antenna windings (tracks) 42. The antenna 40 includes an antenna section 41 that extends from the in the FIGS. 1a and 1c shown internal position in the in Figures 1b and 1d shown external position and back is pivotal. For this purpose, it is arranged on the key body 20 via a pivot axis 22 (eg, a joint) running parallel to the main plane of the key body 20 (and the antenna surface spanned by the antenna windings 42 to the main plane).

Wie in den Figuren 1c und 1d ersichtlich ist, ist in der Externposition die von den Antennenwindungen 42 umschlossene Antennenfläche viel größer (etwa doppelt so groß) als in der Internposition. Generell ist es bei der vorliegenden Erfindung vorteilhaft, wenn die Antennenfläche in der Externposition größer ist als die Fläche des Schlüsselkörpers 20 in seiner Hauptebene, was bei dem vorliegenden Ausführungsbeispiel der Fall ist. Wie in den Figuren 1c und 1d weiterhin ersichtlich ist, verlaufen die Antennenwindungen 42 in der Externposition über die Schwenkachse 22 entlang des Randes des Antennenabschnitts 41. In der Internposition verlaufen die Antennenwindungen 42 hinter der Schwenkachse 22 entlang des Randes des Schlüsselkörpers 20. Dies wird durch entsprechende Kontakte im Bereich der Schwenkachse 22 ermöglicht, die beim Auf- bzw. Zuklappen des Schlüssels 10 zwischen den durch den Antennenabschnitt 41 oder im Bereich der Schwenkachse 22 entlang des Randes des Schlüsselkörpers 20 verlaufenden Leiterbahnen hin - und herschalten. Dementsprechend ist die Antenne 40 auch in der Internposition verwendbar.As in the Figures 1c and 1d As can be seen, in the external position, the antenna area enclosed by the antenna windings 42 is much larger (about twice as large) than in the internal position. In general, it is advantageous in the present invention if the antenna surface in the external position is larger than the area of the key body 20 in its main plane, which is the case in the present embodiment. As in the Figures 1c and 1d In the internal position, the antenna windings 42 extend behind the pivot axis 22 along the edge of the key body 20. This is done by corresponding contacts in the region of the pivot axis 22nd allows, when switching on or folding the key 10 between the passing through the antenna section 41 or in the region of the pivot axis 22 along the edge of the key body 20 tracks back and forth. Accordingly, the antenna 40 is usable also in the internal position.

Der Kraftfahrzeugschlüssel 10 ist zudem mit einer Datenträgereinheit 30 ausgestattet, die zwischen der in den Figuren 1a und 1c dargestellten Schutzposition und der in den Figuren 1b und 1d dargestellten Kontaktierungsposition bewegbar an dem Schlüsselkörper 20 angeordnet ist.The motor vehicle key 10 is also equipped with a data carrier unit 30, which between the in the FIGS. 1a and 1c shown protection position and in the Figures 1b and 1d shown contacting position is movably arranged on the key body 20.

Die Datenträgereinheit 30 besitzt eine USB-Schnittstelle 31 (alternativ z.B. Firewire-Schnittstelle), die in der Kontaktierungsposition aus dem Schlüsselkörper 20 hervorsteht und dementsprechend kontaktierbar ist. In der Schutzposition ist die USB-Schnittstelle 31 durch den Schlüsselkörper 20 vor mechanischer Beschädigung geschützt. Die Datenträgereinheit 30 wird durch geeignete Haltemittel manuell lösbar in der Schutz- und/oder der Kontaktierungsposition gehalten. Zudem sind Endanschläge vorgesehen, so dass die Datenträgereinheit 30 nicht über die Schutzposition hinaus in den Schlüsselkörper 20 eingeschoben werden kann und nicht über die Kontaktierungsposition hinaus herausgezogen werden kann. Die Datenträgereinheit kann manuell (ohne Werkzeug) von dem Schlüsselkörper 20 entfernt und wieder daran angeordnet werden.The data carrier unit 30 has a USB interface 31 (alternatively eg Firewire interface), which protrudes from the key body 20 in the contacting position and can therefore be contacted. In the protection position, the USB interface 31 is protected by the key body 20 from mechanical damage. The data carrier unit 30 is held by suitable holding means manually detachable in the protective and / or the contacting position. In addition, end stops are provided so that the data carrier unit 30 can not be inserted beyond the protective position into the key body 20 and can not be pulled out beyond the contacting position. The volume unit can be manually removed (without tools) from the key body 20 and be placed back on it.

Diese Datenträgereinheit 30 ist zur Datenkommunikation mittels der Antenne 40 ausgestaltet und besitzt zu diesem Zweck Kontaktflächen 32, die (nur) in der Kontaktierungsposition einen elektrischen Kontakt zu Kontaktflächen 43 an den Enden der Antennenwindungen 42 erzeugen.This data carrier unit 30 is designed for data communication by means of the antenna 40 and for this purpose has contact surfaces 32 which (only) in the contacting position make electrical contact with contact surfaces 43 at the ends of the antenna windings 42.

Weiterhin ist an der Unterseite der Datenträgereinheit 30 eine Nase 34 angeordnet, die ein Klappen des Antennenabschnitts 41 von der Internposition in die Externposition verhindert, wenn sich die Datenträgereinheit 30 in der Schutzposition befindet. Die Nase 34 erstreckt sich vorzugsweise über die gesamte Breite der Datenträgereinheit 30 und dient gleichzeitig zum Herausschieben der Datenträgereinheit 30 aus der Schutzposition in die Kontaktierungsposition. Optional kann noch eine Feder vorhanden sein, die den Antennenabschnitt 41 von der Internposition in die Externposition klappt, sobald die Datenträgereinheit 30 von der Schutzposition in die Kontaktierungsposition gebracht wird.Furthermore, a nose 34 is arranged on the underside of the data carrier unit 30, which prevents the antenna portion 41 from folding from the internal position into the external position when the data carrier unit 30 is in the protective position. The nose 34 preferably extends over the entire width of the data carrier unit 30 and at the same time serves to push out the data carrier unit 30 from the protective position into the contacting position. Optionally, a spring may still be present, which folds the antenna section 41 from the internal position into the external position as soon as the data carrier unit 30 is brought from the protective position into the contacting position.

Schließlich ist an der Datenträgereinheit 30 noch eine Kurzschlussfläche 33 angeordnet, die Leiterbahnen 42 der Antenne 40 kurzschließt, wenn sich die Datenträgereinheit 30 in der Internposition befindet. Dadurch soll eine Datenkommunikation mittels der Antenne 40 sicher unterbunden werden, wenn sich die Datenträgereinheit 30 in der Schutzposition befindet, insbesondere auch wenn auf Grund eines z.B. durch Manipulation hervorgerufenen Defekts sowohl in der Schutzposition als auch in der Kontaktierungsposition ein Kontakt zwischen den Kontaktflächen 32, 43 besteht. Alternativ dazu kann die Datenträgereinheit 30 auch konstruktionsgemäß derart mit der Antenne 40 verbunden sein, dass sowohl in der Schutz- als auch in der Kontaktierungsposition ein Kontakt zwischen der Datenträgereinheit 30 und der Antenne 40 besteht, z.B. mittels flexibler Leiterbahnen oder geeigneten Kontakten. Dadurch kann sowohl in der Schutz- als auch in der Kontaktierungsposition eine entsprechende Datenkommunikation ermöglich werden. Weiterhin kann es z.B. aus Kostengründen auch sinnvoll sein, den Schlüssel so auszugestalten, dass in beiden Positionen ein Kontakt zwischen der Datenträgereinheit 30 und der Antenne 40 besteht (z.B. mittels flexibler Leiterbahnen) und die Antenne 40 in der Schutzposition mittels der zuvor beschriebenen Kurzschlussfläche 33 kurzzuschließen, um sie in dieser Position zu deaktivieren.Finally, a short-circuit surface 33 is arranged on the data carrier unit 30, which short-circuits conductor tracks 42 of the antenna 40 when the data carrier unit 30 is in the internal position. This is intended to reliably prevent data communication by means of the antenna 40 when the data carrier unit 30 is in the protection position, in particular even if there is a contact between the contact surfaces 32, 43 due to eg a defect caused by manipulation both in the protective position and in the contacting position consists. Alternatively, the data carrier unit 30 may also be structurally connected to the antenna 40 such that both in the protective and in the Contacting position is a contact between the data carrier unit 30 and the antenna 40, for example by means of flexible tracks or suitable contacts. As a result, corresponding data communication can be enabled both in the protective and in the contacting position. Furthermore, it may also be useful, for cost reasons, for example, to design the key such that a contact between the data carrier unit 30 and the antenna 40 exists in both positions (eg by means of flexible printed conductors) and short-circuit the antenna 40 in the protective position by means of the short-circuiting surface 33 described above to disable them in this position.

Die Datenträgereinheit ermöglicht eine Datenkommunikation gemäß dem NFC-Standard (Near Field Communication) und/oder gemäß der RFID-Technologie (Radio Frequency Identification). Die Datenträgereinheit besitzt eine Drahtlos-Kommunikationseinheit, einen Speicher, insbesondere einen nicht-flüchtigen Speicher, einen Speichercontroller, sowie einen Smartcard-Chip. Die Datenträgereinheit 30 stellt mittels der Drahtlos-Kommunikationseinheit, dem Smart-Card-Chip und dem Speicher Bezahlfunktionen sowie weitere Funktionalitäten bereit. Auf den Smart-Card-Chip und den Speicher kann über die USB-Schnittstelle 31 zugegriffen werden, sowie kontaktlos mittels der Drahtlos-Kommunikationseinheit und der Antenne 40. Dabei können Programme auf den Speicher und den Smart-Card-Chip geladen werden und bei Bedarf aktiviert oder gesperrt werden. Ein Interface des Smart Card Chips folgt ISO 7816.The data carrier unit enables data communication in accordance with the NFC standard (Near Field Communication) and / or according to the RFID technology (Radio Frequency Identification). The data carrier unit has a wireless communication unit, a memory, in particular a non-volatile memory, a memory controller, and a smart card chip. The data carrier unit 30 provides payment functions and further functionalities by means of the wireless communication unit, the smart card chip and the memory. The smart card chip and the memory can be accessed via the USB interface 31, as well as contactlessly by means of the wireless communication unit and the antenna 40. Programs can be loaded onto the memory and the smart card chip and, if required be activated or locked. An interface of the smart card chip follows ISO 7816.

Die Datenträgereinheit 30 ist vor Manipulation geschützt und eingerichtet, eine elektronische Bezahlung zu ermöglichen. Hierzu ist die Antenne 40 in der Internposition und/oder der Externposition auf eine Frequenz von 13,56 MHz abgestimmt.The data carrier unit 30 is protected against manipulation and arranged to allow electronic payment. For this purpose, the antenna 40 is tuned in the internal position and / or the external position to a frequency of 13.56 MHz.

Der Kraftfahrzeugschlüssel 10 umfasst weiterhin zwei Schlüsselantennen 50, eine Schlüsselkommunikationseinheit 52 und eine Batterie 51. Diese Komponenten sind im Schlüsselkörper 20 angeordnet und über die Leitungen 53 miteinander verbunden. Sie dienen insbesondere dazu, eine Zentralverriegelung des Kraftfahrzeugs anzusteuern, sowie das Starten des Kraftfahrzeugs per Funk freizugeben. Eine der Schlüsselantennen 50 ist auf eine Frequenz von 128 kHz zur Kommunikation mit einem Board-Computer des Kraftfahrzeugs ausgelegt und die Andere auf eine Frequenz von 433 MHz zum Ansteuern der Zentralverrieglung. Da sich die Antennenabschnitte 41 der Antenne 40 in der Externposition zumindest teilweise außerhalb des Schlüsselkörpers 20 befinden, beeinträchtigen in dieser Position die Schlüsselantennen 50 (sowie die Schlüsselkommunikationseinheit 52 und die Batterie 51) die Datenkommunikation mittels der Antenne 40 nur geringfügig.The motor vehicle key 10 further comprises two key antennas 50, a key communication unit 52 and a battery 51. These components are arranged in the key body 20 and connected to each other via the lines 53. They serve in particular to control a central locking of the motor vehicle, as well as to release the starting of the motor vehicle by radio. One of the key antennas 50 is designed to have a frequency of 128 kHz for communication with a board computer of the motor vehicle and the other to a frequency of 433 MHz for driving the Zentralverrieglung. In this position, since the antenna portions 41 of the antenna 40 are at least partially outside the key body 20 in the external position, the key antennas 50 (as well as the key communication unit 52 and the battery 51) only slightly impair the data communication by the antenna 40.

Die Datenträgereinheit 30 kann weiterhin einen Schlüsselinterface-Controller aufweisen, mittels dem sie auf Funktionalitäten der Schlüsselkommunikationseinheit 52 und auf darauf gespeicherte Daten zugreifen kann. Eine hierzu erforderlicher elektrischer Kontakt kann mittels Kontaktflächen (analog zu den Kontaktflächen 32, 43) bereitgestellt werden. Zudem kann eine Zugriffsmöglichkeit von der Schlüsselkommunikationseinheit 52 auf die Datenträgereinheit 30, insbesondere den Speicher, den Smart-Card-Chip und die Drahtlos-Kommunikationseinheit mittels des Schlüsselinterface-Controllers bestehen (z.B. über ein I2C Interface).The data carrier unit 30 may further comprise a key interface controller by means of which it can access functionalities of the key communication unit 52 and data stored thereon. A required for this electrical contact can be provided by means of contact surfaces (analogous to the contact surfaces 32, 43). In addition, an access possibility from the key communication unit 52 to the data carrier unit 30, in particular the memory, the smart card chip and the wireless communication unit can exist by means of the key interface controller (for example via an I2C interface).

Der Schlüsselkörper 20 hat eine Breite b von 35 mm, eine Tiefe t von 64 mm und eine Höhe h von 11,5 mm (ohne den Antennenabschnitt 41, der z.B. 0,5 mm, oder 2 mm dick sein kann). Die Materialstärke der Außenwände des Schlüsselkörpers beträgt 2 mm. Figuren 1c und 1d geben die tatsächliche Form des Schlüsselkörpers 20 wieder.The key body 20 has a width b of 35 mm, a depth t of 64 mm and a height h of 11.5 mm (without the antenna portion 41, which may be, for example, 0.5 mm, or 2 mm thick). The material thickness of the outer walls of the Key body is 2 mm. Figures 1c and 1d give the actual shape of the key body 20 again.

In Figur 2 ist ein Kraftfahrzeugschlüssel gemäß einer zweiten Ausführungsform dargestellt. Dieser ist nahezu identisch zu dem Kraftfahrzeugschlüssel gemäß der ersten Ausführungsform aufgebaut, mit dem einzigen Unterschied, dass die Antennenwindungen 42 der Antenne 40 stets, d.h. auch in der in Figur 2 dargestellten Internposition über die Schwenkachse 22 durch den Antennenabschnitt 41 verlaufen. Das bedeutet, dass die Antennenwindungen 42 in dem Antennenabschnitt 41 entgegengesetzt zu den Antennenwindungen 42 im Schlüsselkörper 20 verlaufen. Die Antennenwindungen 42 verlaufen also derart, dass die von den Antennenwindungen 42 aufgespannte Antennenfläche in der Internposition (nahezu) null ist, wodurch eine Datenkommunikation mittels der Antenne 40 in dieser Position verhindert wird. Dieses Deaktivieren der Antenne in der Internposition kann erwünscht sein. Falls jedoch auch in der Internposition eine Datenkommunikation mittels der Datenträgereinheit 30 möglich sein soll, können hierzu noch zusätzliche Antennenwindungen vorgesehen werden, die in der Internposition als Antenne 40 genutzt werden.In FIG. 2 a motor vehicle key according to a second embodiment is shown. This is constructed almost identical to the motor vehicle key according to the first embodiment, with the only difference that the antenna windings 42 of the antenna 40 always, ie also in the in FIG. 2 shown internal position on the pivot axis 22 extend through the antenna section 41. That is, the antenna windings 42 in the antenna portion 41 are opposite to the antenna windings 42 in the key body 20. The antenna windings 42 thus run in such a way that the antenna area spanned by the antenna windings 42 in the internal position is (almost) zero, whereby data communication by means of the antenna 40 in this position is prevented. This deactivation of the antenna in the internal position may be desired. If, however, data communication by means of the data carrier unit 30 should also be possible in the internal position, additional antenna windings can be provided for this purpose which are used in the internal position as the antenna 40.

Die Figuren 3a, 3b und 3c zeigen einen Kraftfahrzeugschlüssel gemäß einer dritten Ausführungsform. Dieser besitzt zwei um senkrecht zu der Hauptebene des Schlüsselkörpers 20 verlaufende Schwenkachsen 25a, 25b schwenkbare Antennenabschnitte 41a, 41b, die beide parallel zu der Hauptebene des Schlüsselkörpers 20 verlaufen. Diese befinden sich in Figur 3a in der Internposition und in Figur 3c in der Externposition. Figur 3b zeigt den Schlüssel 10 von Figur 3a auf eine Ebene projiziert. In der Internposition überlappen sich die dreiecksförmigen Antennenabschnitte 41a, 41b gerade nicht, d.h. sie sind in der Internposition besonders platzsparend in dem Schlüsselkörper 20 untergebracht. Die Antennenwindungen (in den Figuren 3a, 3b und 3c nicht dargestellt) können über geeignete Kontaktflächen derart entlang der Außenkante der Antennenabschnitte 41a, 41b und des Schlüsselkörpers 20 geführt werden, dass die durch die Antennenwindungen 42 aufgespannte Antennenfläche nahezu die gesamte in Figur 3c ersichtliche Fläche von Schlüsselkörper 20 und herausgeklappten Antennenabschnitten 41a, 41b ausmacht. Wie im Zusammenhang mit dem Schlüssel gemäß der zweiten Ausführungsform beschrieben, können auch bei der vorliegenden dritten Ausführungsform, zusätzliche Antennenwindungen vorgesehen sein, die in der Internposition als Antenne 40 genutzt werden. Des Weiteren können die Antennenabschnitte 41a, 41b und der Schlüsselkörper 20 auch jeweils separate Antennenwindungen aufweisen, die zusammen als Antenne 40 genutzt werden. Die Antennenfläche bemisst sich dann nach der insgesamt durch die Antennenwindungen eingeschlossenen Fläche.The Figures 3a, 3b and 3c show a motor vehicle key according to a third embodiment. This has two pivotable about perpendicular to the main plane of the key body 20 pivot axes 25a, 25b antenna portions 41a, 41b, both of which are parallel to the main plane of the key body 20. These are located in FIG. 3a in the internal position and in Figure 3c in the external position. FIG. 3b shows the key 10 of FIG. 3a projected onto a plane. In the internal position, the triangular antenna sections 41a, 41b just do not overlap, ie they are particularly space-saving in the internal position in the internal position Key body 20 housed. The antenna windings (in the Figures 3a, 3b and 3c not shown) can be guided over suitable contact surfaces along the outer edge of the antenna sections 41a, 41b and the key body 20 such that the spanned by the antenna windings 42 antenna surface almost the entire in Figure 3c apparent surface of key body 20 and folded out antenna portions 41a, 41b. As described in connection with the key according to the second embodiment, also in the present third embodiment, additional antenna windings can be provided, which are used in the internal position as the antenna 40. Furthermore, the antenna sections 41a, 41b and the key body 20 can each also have separate antenna windings, which are used together as the antenna 40. The antenna area is then measured according to the total area enclosed by the antenna windings.

Die Antennenfläche kann bei geeigneter Ausgestaltung durch Ausklappen der Antennenabschnitte 41a, 41b z.B. um 40 % vergrößert werden. Die Antennenabschnitte 41a, 41b sind aus FR4-Material mit einer Dicke von 0,5 mm gefertigt. Im übrigen ist der Kraftfahrzeugschlüssel 10 gemäß der dritten Ausführungsform analog zu dem der ersten Ausführungsform aufgebaut. Anstatt der Nase 34, die in der ersten Ausführungsform das Ausklappen des Antennenabschnitts 41 verhindert, wenn sich die Datenträgereinheit 30 in der Schutzposition befindet, können z.B. an der Datenträgereinheit 30 geeignete Hervorstehungen vorgesehen sein, die in der Schutzposition in Aussparungen der Antennenabschnitte 41a, 41b greifen, um ein Ausklappen zu blockieren.The antenna surface may be formed by unfolding the antenna sections 41a, 41b, for example, by suitable means. increased by 40%. The antenna portions 41a, 41b are made of FR4 material having a thickness of 0.5 mm. Incidentally, the motor vehicle key 10 according to the third embodiment is constructed analogously to that of the first embodiment. Instead of the nose 34, which prevents the unfolding of the antenna portion 41 in the first embodiment when the data carrier unit 30 is in the protection position, e.g. on the data carrier unit 30 suitable Auserstehungen be provided, which engage in the protective position in recesses of the antenna sections 41a, 41b to block an unfolding.

Bei dem in den Figuren 4a und 4b dargestellten Kraftfahrzeugschlüssel 10 gemäß einer vierten Ausführungsform sind zwei sich nahezu vollständig überlappende Antennenabschnitte 41a, 41b vorgesehen, die um die im Bereich einer Kante des Schlüsselkörpers 20 befindlichen senkrecht zu der Hauptebene des Schlüsselkörpers 20 verlaufende Schwenkachsen 25a, 25b schwenkbar sind. Die Antennenfläche kann bei geeigneter Ausgestaltung durch Ausklappen der Antennenabschnitte 41a, 41b z.B. um 37 % vergrößert werden. Wenn sich die Antennenabschnitte 41a, 41b in der Internposition befinden und sich die Datenträgereinheit 30 in der Schutzposition befindet, stoßen die Antennenabschnitte 41a, 41b an der Datenträgereinheit 30 an. Dementsprechend blockiert die in der Schutzposition befindliche Datenträgereinheit 30 das Ausklappen der Antennenabschnitte 41a, 41b. Dabei lässt sich das Ausklappen der Antennenabschnitte 41a, 41b durch Bewegen der Datenträgereinheit 30 in die Kontaktierungsposition freigeben. Im übrigen ist der Kraftfahrzeugschlüssel 10 gemäß der vierten Ausführungsform analog zu dem der dritten Ausführungsform aufgebaut.In the in the FIGS. 4a and 4b shown motor vehicle key 10 according to a fourth embodiment, two are almost complete overlapping antenna sections 41a, 41b are provided, which are pivotable about the pivot axes 25a, 25b located in the region of an edge of the key body 20 perpendicular to the main plane of the key body 20. By suitable configuration, the antenna surface can be increased by 37% by unfolding the antenna sections 41a, 41b, for example. When the antenna sections 41a, 41b are in the internal position and the data carrier unit 30 is in the protection position, the antenna sections 41a, 41b abut on the data carrier unit 30. Accordingly, the data carrier unit 30 located in the guard position blocks the unfolding of the antenna sections 41a, 41b. In this case, the unfolding of the antenna sections 41a, 41b can be released by moving the data carrier unit 30 into the contacting position. Incidentally, the motor vehicle key 10 according to the fourth embodiment is constructed analogously to that of the third embodiment.

Die Datenträgereinheit 30 verleiht dem Kraftfahrzeugschlüssel 10 die Funktionalität einer Kontaktloskarte. Dementsprechend ist in Figur 4b zur Illustration der Größenverhältnisse zudem unterhalb des Schlüssels 10 eine ID1-Kontaktloskarte 60 dargestellt. Die ID1-Kontaktloskarte 60 ist ca. 86 mm breit und ca. 54 mm hoch. Die Schlüsselkörper ist, wie im Zusammenhang mit Figur 1c erläutert, 64 mm tief und 35 mm breit. In allen Ausführungsbeispielen kann die Datenträgereinheit 30 bei in der Externposition befindlichem Antennenabschnitt 41 oder befindlichen Antennenabschnitten 41a, 41b wegen der relativ großen Antennenfläche sowohl als NFC-Transponder ("Being Card") als auch als NFC-Lesegerät ("Being Reader") arbeiten. In der Internposition ist mittels der begrenzten Antennenfläche die Funktionalität eines NFC-Transponders realisierbar (mit im Vergleich zur Externposition geringerer Reichweite). Analog zu den oben beschriebenen Ausführungsbeispielen kann durch die vorliegende Erfindung auch ein Kraftfahrzeugschlüssel 10 bereitgestellt werden, der kleiner ist als die Kraftfahrzeugschlüssel 10 gemäß der obigen Ausführungsbeispiele, jedoch trotzdem Dank des zumindest einen bewegbaren Antennenabschnitts 41 in der Externposition zumindest als Transponder arbeiten kann.The data carrier unit 30 gives the motor vehicle key 10 the functionality of a contactless card. Accordingly, in FIG. 4b to illustrate the size ratios also below the key 10 an ID1 contactless card 60 shown. The ID1 contactless card 60 is about 86 mm wide and about 54 mm high. The key body is how related to Figure 1c explained, 64 mm deep and 35 mm wide. In all of the embodiments, the data carrier unit 30 may operate both as an NFC transponder ("Being Card") and as an NFC reader ("Being Reader") in the external position located antenna portion 41 or antenna portions 41a, 41b because of the relatively large antenna area. In the internal position, the functionality of an NFC transponder can be realized by means of the limited antenna area (with a shorter range compared to the external position). Analogous to the embodiments described above, the present invention can also be a motor vehicle key 10, which is smaller than the motor vehicle key 10 according to the above embodiments, but nevertheless can operate at least as a transponder thanks to the at least one movable antenna section 41 in the external position.

Der in Figur 5 dargestellte Kraftfahrzeugschlüssel 10 gemäß der fünften Ausführungsform ist im Wesentlichen identisch zu dem Kraftfahrzeugschlüssel 10 gemäß der vierten Ausführungsform aufgebaut. Der einzige Unterschied besteht darin, dass die Antennenabschnitte 41a, 41b etwas anders geformt sind, oberhalb oder unterhalb der Datenträgereinheit 30 im Schlüsselkörper 20 angeordnet sind und durch eine (runde) Hervorstehung 35 der Datenträgereinheit 30 in der Internposition gehalten werden, wenn sich die Datenträgereinheit 30 in der Schutzposition befindet. Die Antennenfläche kann bei geeigneter Ausgestaltung durch Ausklappen der Antennenabschnitte 41a, 41b z.B. um 45 % vergrößert werden. In Analogie zu der fünften Ausführungsform könnten eine oder mehrere entsprechende Hervorstehungen 35 auch in kurvenförmige Vertiefungen und/oder oder Aussparungen der Antennenabschnitte 41a, 41b greifen, um die Antennenabschnitte 41a, 41b von der Internposition in die Externposition zu schieben, wenn die Datenträgereinheit 30 aus der Schutzposition in die Kontaktierungsposition geschoben wird.The in FIG. 5 illustrated motor vehicle key 10 according to the fifth embodiment is constructed substantially identical to the motor vehicle key 10 according to the fourth embodiment. The only difference is that the antenna sections 41a, 41b have a slightly different shape, are arranged above or below the data carrier unit 30 in the key body 20 and are held in the internal position by a (round) protrusion 35 of the data carrier unit 30 when the data carrier unit 30 is in the protection position. By suitable configuration, the antenna area can be increased by 45% by unfolding the antenna sections 41a, 41b, for example. In analogy to the fifth embodiment, one or more corresponding protrusions 35 could also engage in curved recesses and / or recesses of the antenna sections 41a, 41b to push the antenna sections 41a, 41b from the internal position to the external position when the data carrier unit 30 is out of the Protective position is pushed into the contacting position.
