Die Erfindung bezieht sich auf ein Antennenmodul gemäß dem Oberbegriff des Anspruchs 1. Derartige Antennenmodule finden in der Fahrzeugtechnik Anwendung, um Funkdienste wie Rundfunkempfang (analog, digital), Fernsehempfang (analog, digital), GPS-Information, Fahrzeugzugangskontrollsystem, Steuerung der Wegfahrsperre, Freigabe des Motorstarts, Vornahme von persönlichen Einstellungen, Innenraumüberwachung, Parkhilfe, Reifendruckkontrolle, Mobilfunktelephonie (GMS-Bänder, UMTS), Standheizung, Fernstart, Bluetooth, WLAN etc. zu ermöglichen.The invention relates to an antenna module according to the preamble of claim 1. Such antenna modules are used in automotive engineering to radio services such as radio reception (analog, digital), television reception (analog, digital), GPS information, vehicle access control system, control of the immobilizer, release the engine start, making personal settings, interior monitoring, parking assistance, tire pressure monitoring, mobile radiotelephony (GMS bands, UMTS), auxiliary heating, remote start, Bluetooth, WLAN etc.
Derartige Dienste erfolgen teilweise getrennt in Dienste für den Fahrzeugaußenraum und Dienste für den Fahrzeuginnenraum, wobei die Dienste auch auf unterschiedlichen Frequenzen (LF, HF) bzw. Bändern übertragen werden. Manche Dienste benötigen dagegen eine über die Fahrzeuggrenze wirkende übergreifende Übertragung, wie beispielsweise die Kommunikation zwischen ID-Geber (Schlüssel) und dem Steuergerät für die Zugangskontrolle, Innenraumüberwachung und Motorstart bzw. Steuerung der Wegfahrsperre, um die genaue Position einer Person festzustellen und entsprechende Aktionen in Abhängigkeit der Position auszulösen.Such services are partly carried out separately in services for the vehicle exterior and services for the vehicle interior, the services also being transmitted on different frequencies (LF, HF) or bands. On the other hand, some services require over-the-vehicle trans-boundary transmission, such as the communication between the ID transmitter (key) and the access control control unit, interior control and engine start or immobilizer control, to determine the exact position of a person and to take appropriate actions in the vehicle Dependence of the position trigger.
Um diese unterschiedlichen Dienste teils auf unterschiedlichen Frequenzen für den Fahrzeugaußenraum und Fahrzeuginnenraum zu ermöglichen, werden üblicherweise mehrere Antennen im Fahrzeug und außerhalb am Fahrzeug angeordnet.In order to enable these different services partly on different frequencies for the vehicle exterior and vehicle interior, usually several antennas are arranged in the vehicle and outside the vehicle.
Die Anordnung einer Vielzahl von Antennen inklusive eventueller Stromversorgung (Steuergeräte und/oder aktive Antennen) und Weiterleitung der übertragenen Signale bedarf jedoch eines erhöhten Verkabelungsaufwandes und ist damit bei der heutigen erhöhten Anzahl von vorhandenen Diensten im Fahrzeug nachteiligerweise in der Fertigung sowie Wartung und etwaigen nachträglichen Installation und Reparatur zeit- und kostenintensiv. Zudem ist eine exakte elektromagnetische Trennung der Antennen bzw. deren Sende- bzw. Empfangsfelder bei der erhöhten Anzahl von Antennen problematisch.The arrangement of a plurality of antennas including any power supply (controllers and / or active antennas) and forwarding the transmitted signals, however, requires increased cabling and is thus in today's increased number of existing services in the vehicle disadvantageously in the production and maintenance and any subsequent installation and repair time consuming and costly. In addition, an exact electromagnetic separation of the antennas or their transmission or reception fields in the increased number of antennas is problematic.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Antennenmodul zu schaffen, welches die vorgenannten Nachteile vermeidet und auf kostengünstige und einfache Art und Weise mehrere Dienste erfüllt und gleichzeitig den Verkabelungsaufwand vermindert und auf einfache Art und Weise zu befestigen ist.The present invention is therefore an object of the invention to provide an antenna module which avoids the aforementioned disadvantages and met in a cost effective and simple way, multiple services while reducing the cabling and easy to attach it.

Erfindungsgemäß weist ein Antennenmodul einen oberen und unteren Teil mit jeweils mehreren Antennen auf, welche durch einen Bereich der Karosserie eines Fahrzeugs getrennt und mechanisch durch den Bereich der Karosserie hindurch miteinander verbunden sind. Durch diese Ausgestaltung ist es vorteilhafterweise möglich, möglichst viele oder gar alle in oder an einem Fahrzeug benötigten Antennen an einem Ort, beispielsweise im hinteren mitteleren Dach- oder Heckbereich, unterzubringen.According to the invention, an antenna module has an upper and lower part, each with a plurality of antennas, which are separated by a region of the body of a vehicle and mechanically connected to each other through the region of the body. By means of this embodiment, it is advantageously possible to accommodate as many as possible or even all of the antennas required in or on a vehicle at one location, for example in the rear central roof or rear area.
In bevorzugter Ausgestaltung der Erfindung überlappen sich der an Karosserieinnenseite und -außenseite angeordnete obere und untere Teil, wobei im Bereich der Überlappung durch wenigstens einen kleinen Durchbruch von wenigen Millimetern durch die Karosserie Befestigungsmittel hindurchführen. Hierdurch ist es vorteilhafterweise möglich, ein Antennenmodul mitsamt oberem und unterem Teil an derselben Stelle bzw. Innen- und Außenseite der Karosserie anzubringen, so dass die Leitungswege auch zwischen dem oberen und unteren Teil des Antennenmoduls gering bleiben.In a preferred embodiment of the invention, the upper and lower parts arranged on the inside and outside of the body overlap, wherein fastening means pass through the body in the region of the overlap by means of at least a small opening of a few millimeters. As a result, it is advantageously possible to mount an antenna module together with the upper and lower parts at the same point or inside and outside of the body, so that the cable paths also remain small between the upper and lower parts of the antenna module.
In weiterer Ausgestaltung der Erfindung bestehen der obere und/oder untere Teil aus einer Grundplatte und/oder Platine, wobei jeweils die Platine und/oder Grundplatte des oberen Teils mit der Platine und/oder Grundplatte des unteren Teils im montierten Zustand mechanisch miteinander verbunden ist. Hierdurch ist vorteilhafterweise ein einfacher Aufbau des Antennenmoduls ermöglicht.In a further embodiment of the invention, the upper and / or lower part of a base plate and / or board, wherein each of the circuit board and / or base plate of the upper part with the board and / or base plate of the lower part in the assembled state is mechanically interconnected. This advantageously allows a simple construction of the antenna module.
Die mechanische Verbindung bzw. Befestigung des Antennenmoduls kann als zerstörungsfrei lösbare Verbindung, beispielsweise als Schraub-, Einrast- oder Einclipsverbindung, ausgebildet sein, so dass eine Reparatur, Wartung, Änderung der Konfiguration (Hardware) auf einfach Art und Weise möglich ist.The mechanical connection or attachment of the antenna module can be configured as a non-destructive detachable connection, for example as a screw, snap-in or Einclipsverbindung, so that a repair, maintenance, change the configuration (hardware) in a simple way is possible.
In besonderer Ausgestaltung der Erfindung weist das Antennenmodul eine fahrzeuginterne Leiterplatte und eine fahrzeugexterne Leiterplatte auf, welche im montierten Zustand eine elektrisch, insbesondere hochfrequenztechnisch, verbundene Massefläche bildet. Hierdurch kann auf einfache Art eine Abschirmung und Anpassung des Antennenmoduls gewährleistet werden, wobei im Sinne einer hochfrequenztechnischen elektrischen Verbindung auch Hohlleiter, wie beispielsweise Rohrzapfen mit beliebigem Grundriss in Frage kommen.In a particular embodiment of the invention, the antenna module on an in-vehicle circuit board and a vehicle-external circuit board, which forms an electrically, in particular high-frequency technical, connected ground surface in the mounted state. As a result, a shielding and adaptation of the antenna module can be ensured in a simple manner, in the sense of a high-frequency electrical connection and waveguide, such as pipe tap come with any layout in question.

Das in Fig. 1 dargestellte Antennenmodul weist an seiner Außenseite beispielsweise auf einem Fahrzeugdach, vorzugsweise im mittleren hinteren Bereich oder an einem Fahrzeugheck, einen oberen Teil in Form eines externen Gehäuses 1, beispielsweise in Form einer Finne auf, welches vorzugsweise eine aerodynamische Außenform, also eine in Fahrtrichtung sich verjüngende Form aufweist.The antenna module shown in Fig. 1 has on its outer side, for example on a vehicle roof, preferably in the middle rear region or at a vehicle rear, an upper part in the form of an external housing 1, for example in the form of a fin, which preferably has an aerodynamic outer shape, ie has a tapered shape in the direction of travel.
Unterhalb dieses externen Gehäuses 1 ist an der Innenseite der entsprechenden Stelle des Fahrzeugdachs 5 ein unteres Teil in Form eines internen Gehäuses 3 angeordnet, welches eine flache rechteckige oder beliebige, vorzugsweise andere flache Form aufweist, so dass dieses interne Gehäuse 3 in rechteckiger, runder oder sonstiger Form zwischen dem Autodach und der Dachverkleidung positioniert werden kann.Below this external housing 1, a lower part in the form of an
Wie in Fig. 2 dargestellt, weist das interne Gehäuse 3 eine beispielsweise rechteckige Leiterplatte 7 auf, an deren Unterseite fahrzeuginterne Antennen 8 und an deren Oberseite Transceiver bzw. Sender- und Empfänger in Form von elektronischen Bausteinen, angeordnet sind. Von der Oberseite der vorzugsweise zum Dach 5 parallel angeordneten Leiterplatte 7 erstrecken sich senkrecht in Richtung Dach 5 Verbindungselemente 12, beispielsweise in Form von Bolzen mit Abstandshaltern 27 (Fig. 7), welche durch entsprechende Ausnehmungen, beispielsweise in Form von Bohrungen oder Stanzungen, durch das Dach 5 in das externe Gehäuse 1 hineinreichen.As shown in Fig. 2, the
Weiterhin erstrecken sich von der Leiterplatte 7 senkrecht durch entsprechende Ausnehmungen durch das Dach 5 koaxiale HF-Verbindungselemente 9, 11, welche, wie in Fig. 3 dargestellt, in das externe Gehäuse 1 hineinreichen.Furthermore, coaxial
Im Inneren des externen Gehäuses 1 befindet sich am Dach 5 aufliegend eine obere Grundplatte 17, welche aus Metall, insbesondere Aluminium, gefertigt ist. Auf dieser Grundplatte 17 ist eine obere fahrzeugexterne Leiterplatte 15, beispielsweise durch Einfassung, Kleben, Verschrauben, etc., vorzugsweise die Masse elektrisch verbindend befestigt.In the interior of the external housing 1 is located on the
Die Verbindungsbolzen 12, vorzugsweise ebenfalls aus Metall, sind mit der oberen Grundplatte 17 und/oder der oberen Leiterplatte 15 mechanisch und masseleitend verbunden, so dass zwischen der unteren Platine 7 und der oberen Platine 17 eine Masseverbindung hergestellt ist.The connecting
Wie in Fig. 3 dargestellt, können stattdessen oder zudem auch die koaxialen HF-Verbindungen 9, 11 bzw. deren äußerer Schirm eine derartige Masseverbindung gewährleisten, so dass durch die kurzen Wege eine induktivfreie hochfrequenztechnisch korrekte Anbindung (hoher Leiterquerschnitt, mehrere Verbindungen, geringe Abstände) der elektrischen Masseflächen der unteren und oberen Leiterplatte 7, 15 ermöglicht wird.As shown in FIG. 3, instead of or in addition, the
Auf der Oberseite der Leiterplatte sind unterschiedliche fahrzeugexterne Antennen 13 angeordnet, deren signaltechnische Verbindung zur unteren Leiterplatte über die koaxialen HF-Verbindungen 9, 11 erfolgt. Zudem können, wie in Fig. 3 dargestellt, zusätzliche Leitungsverbindungen 14 von entsprechenden fahrzeugexternen Antennen 13 durch das Dach 5 hindurch in den unteren Teil 3 hinein und aus diesem über nicht näher dargestellte Anschlüsse herausführen.On the upper side of the printed circuit board different vehicle
Aus dem in Fig. 4 dargestellten Grundriss eines oberen Teils 1 bzw. der oberen Grundplatte 17 wird ersichtlich, dass die Grundplatte mehrere, vorzugsweise sechs, Ausnehmungen 10 aufweist, durch welche die Verbindungsbolzen mit ihren Endbereichen hindurchreichen oder darin abschließen.From the plan view of an upper part 1 or the
In Fig. 5 bis 7 sind unterschiedliche Ausführungsformen einer Befestigungsmechanik eines Antennenmoduls schematisch dargestellt.Various embodiments of a fastening mechanism of an antenna module are shown schematically in FIGS. 5 to 7.
So kann beispielsweise, wie in Fig. 1 dargestellt, statt der unteren Leiterplatte 7 eine untere fahrzeuginterne Grundplatte 19, in welcher die untere Leiterplatte 7 befestigt ist, Befestigungselemente, beispielsweise in Form von Rastelementen 21, aufweisen, welche durch das Dach 5 hindurch in der obere Grundplatte reichen. Diese Rastelemente 21, beispielsweise in Form von längsgeschlitzten Bolzen mit kegelförmigen Vergrößerungen führen durch die Ausnehmungen 10 hindurch und klipsen in diese ein, so dass die nach unten gerichtete Schulter der kegelförmigen Erweiterungen die Grundplatte 17 in Richtung Dach 5 mit einer Andruckkraft beaufschlagt. In dieser Ausgestaltung mit einer zusätzlichen unteren, beispielweise napfförmigen Grundplatte 19 kann ein entsprechend zur Grundplatte 19 komplementär ausgebildeter Gehäusedeckel auch auf die Grundplatte 19 statt auf die untere Leiterplatte 7 direkt aufgeschoben, geklemmt, geklipst, geschraubt oder geklebt werden.Thus, for example, as shown in Fig. 1, instead of the lower circuit board 7, a lower vehicle-
Die in Fig. 6 dargestellte zweite Ausführungsform einer Befestigungsmechanik zeigt dagegen, wie eine untere Leiterplatte 7 ohne zusätzliche Grundplatte 19 mit der oberen Grundplatte 17' mechanisch ortsfest verbunden werden kann. Hierzu weisen die Befestigungselemente, beispielsweise in Form von Bolzen oder Schrauben 23, im Bereich zwischen Oberseite der Leiterplatte 7 und dem Dach 5 Abstandshülsen 27 auf, so dass die Leiterplatte vorzugsweise ohne direkten Kontakt zur Innenseite des Dachs 5 ortsfest befestigt ist. Die Befestigung der Befestigungselemente an der oberen Grundplatte 17' kann hierbei in beliebigen Varianten erfolgen, wobei, wie in Fig. 6 dargestellt, statt einer vorstehend erläuterten Klipsverbindung auch eine Schraubverbindung mit an der Oberseite der Grundplatte 17 aufgeschraubten Muttern möglich ist.The illustrated in Fig. 6 second embodiment of a fastening mechanism, however, shows how a lower circuit board 7 without
Wie in Fig. 7 als dritte Ausführungsform dargestellt, kann der Abschluss der Befestigung an der Oberseite der oberen Grundplatte 17' statt durch aufgeschraubte Muttern auch mittels einschnappender Kopfhülsen erfolgen, wobei die napfförmigen Hülsen nach unten gerichtet einen sich verengenden Innenbereich, beispielsweise in Form einer umlaufenden Wulst, aufweisen, welcher beim Aufschieben in eine entsprechende umlaufende Rille oder Nut der Befestigungselemente, beispielsweise Zapfen 23', einschnappt.As shown in Fig. 7 as a third embodiment, the completion of the attachment to the top of the upper base plate 17 'instead of screwed nuts also take place by means of snapping head sleeves, the cup-shaped sleeves directed down a narrowing inner region, for example in the form of a circumferential Bead, which, when pushed into a corresponding circumferential groove or groove of the fasteners, such as pin 23 ', snaps.
Hierdurch sind die untere Leiterplatte 7 und die obere Grundplatte 17' ebenso wie in der vorstehend beschriebenen zweiten Ausführungsform durch den unteren erweiterten Kopfbereich der Elemente 23 und 23' und den oberen ortsfesten Abschluss 25 und 25' mechanisch orstfest zueinander und am Dach 5 befestigt.As a result, the lower circuit board 7 and the upper base plate 17 'as in the second embodiment described above by the lower extended head portion of the
Eine obere Abdeckung des oberen Teils 1 kann an der oberen Grundplatte beispielsweise mittels Kleben erfolgen, so dass die obere Leiterplatte 15 mit den darauf angeordneten Antennen 13 gegen äußere Einflüsse (Wetter, Fahrtwind, mechanische Beeinträchtigungen) geschützt ist.An upper cover of the upper part 1 can be made on the upper base plate, for example by gluing, so that the
Selbstverständlich können die vorstehend geschilderten Befestigungsarten miteinander kombiniert werden, wobei auch andere mechanische und zusätzlich eine elektrische Masseverbindung gewährleistende Befestigungsarten (Kleben, Nieten, Löten, etc.) denkbar sind. Insbesondere die Klipsverbindung bzw. deren komplementärer Bereich kann mit entsprechenden Nuten, Vorsprüngen, Federelementen, etc, auch innerhalb der Ausnehmungen 10 ausgebildet sein, so dass ein Herausragen der Endbereiche der Befestigungselemente 25, 25' und 21 vermieden werden kann.Of course, the above-described types of attachment can be combined, with other mechanical and in addition an electrical ground connection guaranteeing attachment types (gluing, riveting, soldering, etc.) are conceivable. In particular, the clip connection or its complementary region can be formed with corresponding grooves, projections, spring elements, etc., also within the
Die Klipsverbindung kann vorteilhafterweise einen schnellen Arbeitszyklus von beispielsweise wenigen Sekunden bei der Befestigung des erfindungsgemäßen Antennenmoduls gewährleisten, was sich positiv auf eine Verminderung der Herstellungskosten eines entsprechend ausgerüsteten Fahrzeugs auswirkt.The clip connection can advantageously ensure a fast work cycle of, for example, a few seconds in the attachment of the antenna module according to the invention, which has a positive effect on a reduction in the manufacturing cost of a suitably equipped vehicle.
