Abstract
Description
Die Erfindung betrifft eine fernsteuerbare Zentralverriegelung für Kraftfahrzeuge nach dem Oberbegriff des Anspruches 1.The invention relates to a remote controllable central locking for motor vehicles according to the preamble of
Bekanntermaßen werden derartige Antennenanordnungen für eine funkfernsteuerbare Verriegelungsanlage in einem Kraftfahrzeug beispielsweise im Bereich einer Fensteröffnung angeordnet.As is known, such antenna arrangements are arranged for a radio-controlled locking system in a motor vehicle, for example in the region of a window opening.
Es sind aber auch andere Einbaustellen möglich und denkbar. 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 freiverlegbaren Drahtes nach dem allgemeinen Erkenntnisstand so im Fahrzeug verlegt, dass eine möglichst gute Empfangswirkung realisiert wird.But there are also other installation sites possible and conceivable. The manufacturer, the corresponding electronic devices are shipped housed with their components in a housing, together with an antenna. As a rule, the antenna is designed as a plug-in part which can be plugged into the housing. When installing the antenna is then usually laid in the form of a freiverlegbaren wire after the general state of knowledge in the vehicle that the best possible reception effect is realized.

Die Verwendung einer inverted-F-Antenne ist grundsätzlich im Zusammenhang mit einem elektrischen Gerät auch aus dem US-Patent
Aufgabe der vorliegenden Erfindung ist es, ausgehend von dem vorletzten Stand der Technik, eine verbesserte fernsteuerbare Zentralverriegelung zu schaffen.Object of the present invention is to provide, starting from the penultimate prior art, an improved remote controllable central locking.
Es hat sich 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 Kraftfahrzeugen deutlich abfallen.It has been shown that compared to the prior art, not only significantly improved reception performance in the device according to the invention are possible, but that, above all, no statistical "slip-ups" are to complain, so installation cases, in which under certain conditions, the reception performance compared to other motor vehicles drop significantly.
Die erfindungsgemäße Lösung liegt im Wesentlichen darin, dass bei einer fernsteuerbaren Zentralverriegelung entsprechend dem Oberbegriff des Anspruches 1 eine Antenne verwendet wird, die aus einer inverted-F-Antenne gebildet ist, die als leitende Schicht auf einer als Leiterplatine ausgebildeten Grundplatte vorgesehen ist. Dabei ist die als Leiterplatine ausgebildete Grundplatte steif, besteht also aus einem formstabilen Träger. Möglich ist auch, dass die Antenne auf dem Träger (d.h. auf der aus einer Leiterplatine bestehenden Grundplatte) in Form einer Streifenleiteranordnung (Streifenleitung) ausgebildet ist.The solution according to the invention lies essentially in the fact that, in the case of a remotely controllable central locking according to the preamble of
Zudem ist die eigentliche Antenne selbst nicht durch das Gehäuse geschützt, in welchem das Fernzentralverriegelungs-Modul untergebracht ist. Dadurch fällt zum einen die insgesamt sich ergebende Baugröße geringer aus, was einen Einbau der fernsteuerbaren Zentralverriegelung auch in einem wenig Platz zur Verfügung stellenden Bauraum im Kraftfahrzeug ermöglicht.In addition, the actual antenna itself is not protected by the housing in which the remote central locking module is housed. As a result, on the one hand, the overall resulting size is smaller, which allows installation of the remote-controlled central locking in a small space available space in the motor vehicle.
Zudem ist die Antenne nicht als Steckmodul an der Zentralverriegelung anschließbar, sondern fest und dauerhaft mit der Zentralverriegelung 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.In addition, the antenna is not connectable as a plug-in module to the central locking, but firmly and permanently connected to the central locking. As a result, a compact uniformly manageable unit is formed, in which the antenna comes to lie in a fixed spatial allocation to the module and therefore always the same installation conditions can be realized on site.
In einer bevorzugten Ausführungsform ist dabei die Antenne an dem Träger in einem vorbestimmten Weg längs ausgebildet. Die Antenne kann dabei bevorzugt sogar um Teile des Gehäuses herum verlaufend vorgesehen sein, beispielsweise nach Art eines U in Draufsicht.In a preferred embodiment, the antenna is formed along the carrier in a predetermined path along. The antenna can preferably be provided extending even around parts of the housing running around, for example in the manner of a U in plan view.
Zusammenfassend lässt sich also festhalten, dass die fernsteuerbare Zentralverriegelung für Kraftfahrzeuge eine Antenne umfasst, die auf einem Trägermaterial, beispielsweise 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.In summary, it can thus be stated that the remotely controllable central locking system for motor vehicles comprises an antenna which is formed on a carrier material, for example in the sense of a substrate, fixedly connected thereto, for example in the form of a stripline arrangement. The stripline may optionally be formed following different paths.
Durch die vorliegende Erfindung lassen sich einige wichtige Vorteile realisieren:
- Es ist nur noch ein einziges gemeinsam handhabbares Kombigerät notwendig, bestehend aus der eigentlichen, die elektronischen Komponenten umfassenden Zentralverriegelung, z.B. dem Empfänger und der Antenne. Dadurch verkürzt sich auch die Einbauzeit vor Ort.
- Insgesamt lässt sich ein kompakter Aufbau erzielen, insbesondere dann, wenn die Antenne um das Gehäuse der fernsteuerbaren Zentralverriegelung gebogen verlegt ausgebildet ist.
- Die Verbindung zwischen Antennengehäuse und Antennenelement ist ohne zusätzliche Steckverbindung bzw. als HF-Leitung ausgebildet, wodurch zusätzliche Verluste vermieden werden und auch die Ausfallwahrscheinlichkeit durch ein defektes Kabel oder einen defekten Stecker verringert wird.
- Ferner ergibt sich eine definierte Lage der Antenne und somit eine gleichbleibende elektrische HF-Eigenschaft gegenüber herkömmlichen Lösungen.
- Darüber hinaus lassen sich durch die fernsteuerbare Zentralverriegelung auch Klappergeräusche der Antenne vermeiden, da die Antenne bei Vibrationen des Fahrzeuges nicht gegen Karosserieteile des Fahrzeuges anschlagen kann.
- Schließlich ist aber auch keine weitere HF-Leitung im Kabelbaum notwendig.
- It is only necessary a single combi device to handle together, consisting of the actual, the electronic components comprehensive central locking, such as the receiver and the antenna. This also shortens the installation time on site.
- Overall, a compact design can be achieved, especially when the antenna is designed to be bent around the housing of the remote-controlled central locking system.
- The connection between the antenna housing and antenna element is formed without additional plug connection or as an RF line, whereby additional losses are avoided and the probability of failure is reduced by a defective cable or a defective connector.
- Furthermore, there is a defined position of the antenna and thus a constant electrical RF characteristic over conventional solutions.
- In addition, can be avoided by the remote controllable central locking and rattling noise of the antenna, since the antenna can not strike against body parts of the vehicle during vibration of the vehicle.
- Finally, however, no further HF line in the wiring harness is necessary.
