Description

Fernsteuerbares Gerät, insbesondere fernsteuerbare Zentralverriegelung für KraftfahrzeugeRemote-controllable device, in particular remote-controlled central locking for motor vehicles
Die Erfindung betrifft ein fernsteuerbares Gerät, insbesondere eine fernsteuerbare Zentralverriegelung für Kraftfahrzeuge nach dem Oberbegriff des Anspruches 1.The invention relates to a remotely controllable device, in particular a remotely controllable central locking system for motor vehicles according to the preamble of claim 1.
Bekanntermaßen werden derartige Antennenanordnungen für eine funkfernsteuerbare Verriegelungsanlage in einem Kraftfahrzeug beispielsweise im Bereich einer Fensteröffnung angeordnet.As is known, such antenna arrangements for a radio-controllable locking system in a motor vehicle are arranged, for example, in the region of a window opening.
Es sind aber auch andere Einbaustellen möglich und denk- bar. Herstellerseitig werden dabei die entsprechenden elektronischen Geräte mit ihren Baukomponenten in einem Gehäuse untergebracht ausgeliefert, und zwar zusammen mit einer Antenne. Die Antenne ist in der Regel als im Gehäuse einsteckbares Zusteckteil ausgebildet. Beim Einbau wird dann die Antenne üblicherweise in Form eines freiverleg- baren Drahtes nach dem allgemeinen Erkenntnisstand so im Fahrzeug verlegt, dass eine möglichst gute Empfangswirkung realisiert wird. Aufgabe der vorliegenden Erfindung ist es, ein derartiges fernsteuerbares Gerät, insbesondere eine fernsteuerbare Zentralverriegelung zu verbessern.However, other installation locations are also possible and conceivable. The manufacturer supplies the corresponding electronic devices with their components housed in a housing, together with an antenna. The antenna is usually designed as a plug-in part that can be plugged into the housing. During installation, the antenna is then usually laid in the vehicle in the form of a freely routable wire according to the general state of knowledge in such a way that the best possible reception effect is achieved. The object of the present invention is to improve such a remotely controllable device, in particular a remotely controllable central locking system.
Die Aufgabe wird erfindungsgemäß entsprechend den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.
Es hat sich nunmehr gezeigt, dass durch den Einbau der bisher auf dem Markt erhältlichen fernsteuerbaren Geräte große Schwankungen bezüglich der Empfangsleistung festzustellen sind. Eine der wichtigsten Ursachen hierfür sind die beim Einbau unterschiedlich verlegten Antennenelemente vorzugsweise in Form von Drähten, die je nach Verlegerichtung zu unterschiedlichen Empfangsleistungen führen. Dies gilt vor allem auch für den nachträglichen Einbau derartiger Geräte.It has now been shown that large fluctuations in the reception power can be determined by the installation of the remote-controllable devices previously available on the market. One of the most important reasons for this are the antenna elements that are installed differently during installation, preferably in the form of wires, which lead to different reception powers depending on the direction of installation. This applies above all to the retrofitting of such devices.
Demgegenüber schafft nunmehr die Erfindung mit vergleichsweise einfache Mitteln eine deutliche Verbesserung, die so nicht vorhersehbar war.In contrast, the invention now creates a significant improvement with comparatively simple means that was not predictable in this way.
Es hat sich nämlich gezeigt, dass gegenüber dem Stand der Technik nicht nur deutlich verbesserte Empfangsleistungen bei dem erfindungsgemäßen Gerät möglich sind, sondern dass vor allem auch keine statistischen "Ausrutscher" zu beklagen sind, also Einbaufälle, in denen bei bestimmten Bedingungen die Empfangsleistungen gegenüber anderen Kraftfahr- zeugen deutlich abfallen.It has been shown that compared to the prior art not only significantly improved reception performance is possible with the device according to the invention, but above all that there are no statistical "slips" to complain about, ie installation cases in which, under certain conditions, the reception performance compared to others Motor vehicles fall off significantly.
Die erfindungsgemäße Lösung liegt im Wesentlichen darin, dass das Elektronikmodul, d.h. das fernsteuerbare Gerät auf einem Träger oder einem Gehäuse wie nach dem Stand der Technik untergebracht ist, dass aber nunmehr eine formstabile oder steife Antenne verwendet wird, die aus sich heraus vorne stabil ist oder auf einem steifen oder forms- tabilen Träger gehalten oder aufgebaut ist. Dabei wäre durchaus denkbar, dass an sich die Antenne biegbar ist, gleichwohl aber aus formstabilem Material besteht, also nicht wie ein nichtformstabiler flexibler Draht. Darüber hinaus kann aber auch ein flexibler Draht als Antenne benutzt werden, wenn er zumindest auf einem Träger so gehalten oder verlegt ist, dass er letztlich als insgesamt formstabile Antenne bezeichnet werden kann. Denn entscheidend ist, dass beim Einbau der Antenne bei dem Kraftfahrzeughersteller bei lagerichtigem Einbau des elektronischen Gerätes die Antennen darüber alle gleich verlegt sind.The solution according to the invention essentially lies in the fact that the electronics module, ie the remotely controllable device is accommodated on a carrier or a housing as according to the prior art, but now a dimensionally stable or rigid antenna is used which is inherently stable at the front or is held or constructed on a rigid or dimensionally stable carrier. It would be quite conceivable that the antenna itself is bendable, but nevertheless consists of dimensionally stable material, i.e. not like a non-dimensionally stable flexible wire. In addition, however, a flexible wire can also be used as an antenna if it is at least held or laid on a carrier in such a way that it can ultimately be called an overall dimensionally stable antenna. It is crucial that when the antenna is installed by the motor vehicle manufacturer when the electronic device is installed in the correct position, the antennas are all routed the same way.
Bevorzugt ist dabei ferner die Antenne nicht als Steckmodul an dem Gerät anschließbar, sondern fest und dauerhaft mit dem Gerät verbunden. Dadurch bildet sich eine kompakte einheitlich handhabbare Baueinheit, bei der die Antenne zum Modul in fester räumlicher Zuordnung zu liegen kommt und deshalb immer die gleichen Einbauverhältnisse vor Ort realisierbar sind.Furthermore, the antenna is preferably not connectable to the device as a plug-in module, but rather is permanently and permanently connected to the device. This forms a compact unit that can be handled in a uniform manner, in which the antenna to the module is located in a fixed spatial assignment and therefore the same installation conditions can always be achieved on site.
In einer bevorzugten Ausführungsform ist dabei die Antenne an dem Träger oder Gehäuse in einem vorbestimmten Weg längs verlegt oder ausgebildet. Die Antenne kann dabei bevorzugt sogar um Teile des Trägers oder Gehäuses herum verlaufend verlegt werden, beispielsweise nach Art eines U in Draufsicht.In a preferred embodiment, the antenna is laid or formed longitudinally on the carrier or housing in a predetermined way. The antenna can preferably even be installed running around parts of the carrier or housing, for example in the manner of a U in plan view.
Es sind aber auch Trägermaterialien denkbar, auf denen die Antenne nicht als separates Bauteil auf diesen gehalten, montiert oder verlegt sind. Möglich ist vielmehr auch, dass die Antenne beispielsweise auf einem Trägermaterial im Sinne eines Substrates fest mit diesem verbunden ausgebildet ist, beispielsweise in Form einer Streifenleiteranordnung. Die Streifenleitung kann dabei gegebenenfalls unterschiedlichen Wegen folgend ausgebildet sein, beispielsweise vergleichbar einer Zick-Zack-Struktur oder vergleichbar einem Rechteckimpuls, also quasi mäanderför- mig verlaufend ausgebildet sein.However, there are also conceivable carrier materials on which the antenna is not held on it as a separate component, installed or relocated. Rather, it is also possible for the antenna to be embodied, for example, on a carrier material in the sense of a substrate, for example in the form of a stripline arrangement. The stripline can optionally be designed to follow different paths, for example comparable to a zigzag structure or comparable to a rectangular pulse, that is to say quasi-meandering.
Schließlich sind aber auch durchaus schraubenförmige Antennen denkbar, die bevorzugt auf einem die schraubenförmigen Windungen durchdringenden oder außen haltenden Träger fixiert sind.Finally, however, helical antennas are also conceivable, which are preferably fixed on a carrier which penetrates the helical windings or holds them on the outside.
Durch die vorliegende Erfindung lassen sich einige wichtige Vorteile realisieren:Several important advantages can be realized by the present invention:
- Erfindungsgemäß ist nur noch ein einziges gemeinsam handhabbares Kombigerät notwendig, bestehend aus dem eigentlichen, die elektronischen Komponenten umfassenden Gerät, z.B. dem Empfänger und der Antenne. Dadurch verkürzt sich auch die Einbauzeit vor Ort.According to the invention, only a single, jointly manageable combination device is necessary, consisting of the actual device comprising the electronic components, e.g. the receiver and the antenna. This also shortens the installation time on site.
- Insgesamt lässt sich dadurch auch ein kompakter Aufbau erzielen, insbesondere dann, wenn die Antenne um das Gehäuse des fernsteuerbaren Gerätes gebogen verlegt ausgebildet ist.Overall, a compact structure can also be achieved, in particular if the antenna is designed to be bent around the housing of the remotely controllable device.
- Bevorzugt wird die Verbindung zwischen Antennengehäuse und Antennenelement ohne zusätzliche Steckverbindung bzw. als HF-Leitung ausgebildet, wodurch zusätzliche Verluste vermieden werden und auch die Ausfallwahr- scheinlichkeit durch ein defektes Kabel oder einen defekten Stecker verringert wird.The connection between the antenna housing and the antenna element is preferably formed without an additional plug connection or as an HF line, thereby avoiding additional losses and also preventing failure. is probably reduced by a defective cable or a defective plug.
- Ferner ergibt sich erfindungsgemäß eine definierte Lage der Antenne und somit eine gleichbleibende elektrische- According to the invention there is also a defined position of the antenna and thus a constant electrical
HF-Eigenschaft gegenüber herkömmlichen Lösungen.HF property compared to conventional solutions.
- Darüber hinaus lassen sich durch das erfindungsgemäße fernsteuerbare Gerät auch Klappergeräusche der Antenne vermeiden, da die Antenne bei Vibrationen des Fahrzeuges nicht gegen Karosserieteile des Fahrzeuges anschlagen kann.- In addition, rattling noises of the antenna can also be avoided by the remote-controllable device according to the invention, since the antenna cannot strike body parts of the vehicle when the vehicle vibrates.
- Schließlich ist aber auch keine weitere HF-Leitung im Kabelbaum notwendig.- Finally, no further RF line is necessary in the wiring harness.

In Figur 1 ist in schematischer perspektivischer Darstellung ein Kombigerät 1 gezeigt, welches eine fernsteuerbare Zentralverriegelung zeigt.In Figure 1, a combination device 1 is shown in a schematic perspective view, which shows a remote-controlled central locking.
Dieses Kombigerät 1 besteht aus einem elektrischen Gerät 3, d.h. im gezeigten Ausführungsbeispiel aus einem Fern- zentralverriegelungs-Modul 3, welches üblicherweise in einem Gehäuse 5 oder auf einem Träger 51 fest aufgebaut ist. Darüber hinaus umfasst das Kombigerät 1 eine Antenne 7, die im gezeigten Ausführungsbeispiel in schematischer Draufsicht nach Figur 1 aus einem Draht, einer Litze oder einem Rohr, Hohlrohr etc. bestehen kann. Die Antenne 7 ist bevorzugt steckkontaktfrei in das elektrische Gerät 3 hineingeführt und dort elektrisch kontaktiert. Die gesamte Anordnung des elektrischen Gerätes 3 mit seinem Gehäuse 5, das auch als Gehäuseschale 5 ausgebildet sein kann, ist mit der Antenne 7 auf einer gemeinsamen Grundplatte 5', also allgemein auf einem Träger 5' vor- gesehen bzw. montiert. Dadurch ist gewährleistet, dass die Antenne 7, selbst wenn sie aus einem verformbaren Draht oder einer Litze bestehen würde, durch auf dem Träger oder der Grundplatte 51 vorgesehenen Fixierungen 9 in fest vorgegebener und im Ausführungsbeispiel gerade verlaufender Ausrichtung dauerhaft angeordnet werden kann.This combination device 1 consists of an electrical device 3, ie, in the illustrated embodiment of a remote central locking module 3, which is usually built in a housing 5 or on a carrier 5 to-1. In addition, the combination device 1 comprises an antenna 7, which in the exemplary embodiment shown can consist of a wire, a stranded wire or a tube, hollow tube etc. in a schematic plan view according to FIG. The antenna 7 is preferably inserted into the electrical device 3 without plug contact and electrically contacted there. The entire arrangement of the electrical device 3 with its housing 5, which can also be designed as a housing shell 5, is provided or mounted with the antenna 7 on a common base plate 5 ', that is to say generally on a carrier 5'. This ensures that the antenna 7, even if it would consist of a deformable wire or a braid may be placed permanently in a fixed predetermined and straight running in the embodiment alignment by on the support or the base plate 5 1 provided fixations. 9
Dadurch ergibt sich eine insgesamt einheitlich und gemeinsam handhabbare Baueinheit 13 für das Kombigerät 1 bestehend aus der eigentlichen elektrischen Gerätekomponente 3 und der in fester Lage und Zuordnung dauerhaft positionierten Antenne 7.This results in an overall uniform and jointly manageable unit 13 for the combination device 1 consisting of the actual electrical device component 3 and the antenna 7 permanently positioned in a fixed position and assignment.
Diese Baueinheit 13 kann dann in einem Kraftfahrzeug entsprechend eingebaut werden, wobei über einen Anschluss 15 am Gehäuse 5 ein entsprechender elektrischer Anschluss zur Ausgabe des demodulierten Datensignals zur Verfügung steht, um letztlich z.B. die Zentralverriegelung zu betätigen.This assembly 13 can then be installed accordingly in a motor vehicle, a corresponding electrical connection being available via a connection 15 on the housing 5 for outputting the demodulated data signal in order to ultimately e.g. to operate the central locking.
Anhand von Figur 2 ist in schematischer perspektivischer Darstellung ein abgewandeltes Ausführungsbeispiel gezeigt. Hierdurch ergibt sich eine besonders kompakte Bauanordnung bei vergleichsweise lang dimensioniertem Antennenelement 7 dadurch, dass das Antennenelement 7 von einer Austritts- stelle 19 bezogen auf das elektrische Gerät 3 in Draufsicht quasi U-förmig um das Gehäuse 5 herum geführt ist, und zu einem gezeigten Ausführungsbeispiel gemäß Figur 2 unter Ausbildung von zwei etwa 90° bildenden Knickstellen 21. In einer bevorzugten Ausführungsform kann der Träger 5 oder die Grundplatte 5' auch Teil eines Deckels für das Gehäuse 5 zur Aufnahme des elektrischen Gerätes 3 sein. Die Trag- oder Grundplatte 5' ist dann in Draufsicht grö- ßer dimensioniert als das eigentliche Gehäuse 5 oder die Gehäuseschale 5. Wie in Figur 3 angedeutet ist, ergibt sich dadurch ein seitlich über die Gehäuseschale 5" überstehender Abschnitt des Trägers oder der Grundplatte 5', worüber nunmehr wiederum die Antenne 7 beispielsweise in Form eines Drahtes oder einer Litze fest vorpositioniert verlegt werden kann. Auch dazu sind bevorzugt wieder Halte-Fixier-Nippel 9 oder Stege 9 vorgesehen, so dass der Draht hier eingelegt und dauerhaft fixiert gehalten wird.A modified exemplary embodiment is shown in a schematic perspective illustration with reference to FIG. This results in a particularly compact construction with a comparatively long antenna element 7 in that the antenna element 7 is guided from an exit point 19 with respect to the electrical device 3 in a top view, quasi U-shaped around the housing 5, and to an exemplary embodiment shown according to FIG. 2 with the formation of two kink points 21 which form approximately 90 °. In a preferred embodiment, the carrier 5 or the base plate 5 ′ can also be part of a cover for the housing 5 for receiving the electrical device 3. The support or base plate 5 'is then dimensioned larger in plan view than the actual housing 5 or the housing shell 5. As indicated in FIG. 3, this results in a section of the carrier or the base plate 5 projecting laterally beyond the housing shell 5 " The antenna 7 can now be placed in a pre-positioned position, for example in the form of a wire or a strand, and holding-fixing nipples 9 or webs 9 are again preferably provided for this purpose, so that the wire is inserted here and held permanently in place.
Bei der schematischen Draufsicht gemäß Figur 3 ist dargestellt, dass das Antennenelement beispielsweise noch um eine weitere Knickstelle 21 auch an der Stirnseite des Gehäuses zumindest wieder um ein gewisses Wegstück längs verlegt werden kann.In the schematic plan view according to FIG. 3 it is shown that the antenna element can, for example, also be moved longitudinally by a further distance, at least once more, at a further kink, also on the end face of the housing.
In den Figuren 3a und 3b ist eine Abwandlung zu Figur 3 gezeigt. In Figur 3 ist nämlich die Antenne 7 im wesentlichen an der Längsseite des Gehäuses 5 parallel zu dieser Gehäuseseite auf der Trag- oder Grundplatte 51 verlegt. In Figur 3a ist eine Seitenansicht auf das Gehäuse längs der Pfeildarstellung 10 in Figur 3 wiedergegeben, allerdings mit jener Abweichung zu Figur 3, dass nämlich die Antenne 7 auf der Oberseite des Gehäuses 5 längs zur Oberseite verlegt ist. Bei dem Beispiel gemäß Figur 3b ist die An- tenne auf der Unterseite des Gehäuses verlegt, wobei auch in diesen Fällen wiederum entsprechende Nippel oder Stege 9 zur Fixierung der Antenne oder der Antennenlitze vorgesehen sind. In dem Ausführungsbeispiel gemäß Figur 4 ist eine inver- ted-F-Antenne 7 verwendet worden, wobei ansonsten die Verlegung des Antennenelementes 7 weitgehend jenem Beispiel gemäß Figuren 2 und 3 entspricht.A modification to FIG. 3 is shown in FIGS. 3a and 3b. In Figure 3, namely, the antenna 7 is laid essentially on the longitudinal side of the housing 5 parallel to this housing side on the support or base plate 5 1 . FIG. 3a shows a side view of the housing along the arrow representation 10 in FIG. 3, but with the difference from FIG. 3 that the antenna 7 on the top of the housing 5 is laid lengthways to the top. In the example according to FIG. 3b, the antenna is laid on the underside of the housing, with corresponding nipples or webs 9 again being provided in these cases for fixing the antenna or the antenna strand. In the exemplary embodiment according to FIG. 4, an inverted-F antenna 7 has been used, the rest of the laying of the antenna element 7 largely corresponding to that of FIGS. 2 and 3.
Anhand von Figur 5 ist gezeigt, dass beispielsweise auf der Grund- oder Trägerplatte 5', die vorzugsweise aus einer Leiterplatine besteht, die Antenne 7 auch als Streifenleiterelement oder als durch Ätzen zurückbelassenes leitendes Antennenelement gebildet sein kann, welches unterschiedlichste Formen aufweisen kann. Bei dem Ausführungsbeispiel gemäß Figur 6 ist eine rechteckförmige Grundstruktur, vergleichbar einer mäanderförmigen Struktur gewählt .It is shown on the basis of FIG. 5 that, for example, on the base or carrier plate 5 ', which preferably consists of a printed circuit board, the antenna 7 can also be formed as a strip conductor element or as a conductive antenna element left behind by etching, which can have a wide variety of shapes. In the exemplary embodiment according to FIG. 6, a rectangular basic structure, comparable to a meandering structure, is selected.
Anhand von Figur 6 ist lediglich dargestellt, dass als Antennenelement beispielsweise aber auch eine Drahtspule in Betracht kommt. Auch diese ist bevorzugt auf einem Träger oder einer Grundplatte, insbesondere einer Leiterplatine gehalten und befestigt. Genauso kann aber das Spulenelement durch einen Träger oder die Leiterplatine mit einem den Innenraum des Spulenelementes durchragenden dornartigen Element gehalten sein.With the aid of FIG. 6, it is only shown that, for example, a wire coil can also be used as the antenna element. This too is preferably held and fastened on a carrier or a base plate, in particular a printed circuit board. In the same way, however, the coil element can be held by a carrier or the printed circuit board with a mandrel-like element which projects through the interior of the coil element.
Anhand von Figur 7 ist ein abgewandeltes Ausführungsbeispiel wiedergegeben, bei welchem die Grundplatte 51 sich an allen Seiten über das Gehäuse 5 hinweg erstreckt, so dass auf dieser Grundplatte 5' auch eine Dipolantenne 7 angebaut werden kann. Die beispielsweise wieder aus Dräh- ten oder Litzen bestehende Dipolantenne 7 kann ebenfalls wieder durch Fixierungen 9 (Fixierstege, Fixiernoppen und dgl.) gehalten werden. Bei dem Ausführungsbeispiel gemäß Figur 8 ist anstelle einer Dipolantenne 7 eine Schleifenantenne verwendet worden, die auf der Grundplatte 5' um das gesamte Gehäuse 5 herum verlegt ist, bei der also in Ergänzung zu der Dipolantennen-Darstellung gemäß Figur 7 die freien Dipolenden durch einen Verbindungsabschnitt zur Schleife geschlossen sind. Weitere Abwandlungen sind möglich. In Figur 8 sind dabei die weiteren Fixierungen auf der Grundplatte 5' zum Halten der Antenne nicht näher dargestellt. Referring to Figure 7 a modified embodiment is shown, wherein the base plate 5 1 extends on all sides over the housing 5 of time, can be so mounted on said base plate 5 'also a dipole antenna. 7 The dipole antenna 7, which again consists, for example, of wires or strands, can also be held again by means of fixings 9 (fixing webs, fixing knobs and the like). In the exemplary embodiment according to FIG. 8, instead of a dipole antenna 7, a loop antenna has been used, which is laid on the base plate 5 'around the entire housing 5, in which, in addition to the dipole antenna representation according to FIG. 7, the free dipole ends through a connecting section are closed to the loop. Further modifications are possible. In Figure 8, the further fixations on the base plate 5 'for holding the antenna are not shown in detail.
