Description

Die Erfindung betrifft eine Fernsteuerungsvorrichtung für die Funkfernsteuerung von Modellen, wie insbesondere Flug-, Fahrzeug- und/oder Schiffsmodellen, nach dem Oberbegriff des Anspruchs 1. Dabei weist die Fernsteuerungsvorrichtung eine Antenneneinrichtung mit mehreren Antennenteilen auf, mittels denen entsprechend einer Richtantenne eine gerichtete Sende-/Empfangscharakteristik erzeugbar ist. Ferner weist die Fernsteuerungsvorrichtung eine Elektronik auf, die wenigstens eine Leiterplatte umfasst.The invention relates to a remote control device for the radio remote control of models, in particular aircraft, vehicle and / or ship models, according to the preamble of claim 1. In this case, the remote control device has an antenna device with a plurality of antenna parts, by means of which according to a directional antenna a directional transmission / Receiving characteristic is generated. Furthermore, the remote control device has electronics which comprises at least one printed circuit board.

WO 99/25441 beschreibt eine Fernsteuerungsvorrichtung mit einer Antenne, die auf einer flexiblen Platte aufgetragen ist, die sich besonders gut in ein Gehäuse integrieren lässt. Die Antenne weist eine gewisse Richtcharakteristik auf und ist mit einer auf einer steifen Elektronikleiterplatte angebrachten Elektronik verbunden. WO 99/25441 describes a remote control device with an antenna, which is applied to a flexible plate, which can be particularly well integrated into a housing. The antenna has a certain directional characteristic and is connected to a mounted on a rigid electronic circuit board electronics.

Aus JP 2008 237528 A ist eine Fernsteuerungsvorrichtung zur Funkfernsteuerung eines Modells bekannt. Diese weist eine Antenneneinrichtung auf, die zwei zueinander V-förmig angeordnete Dipol-Antennen umfasst. Die über die Antenneneinrichtung abgegebenen Steuerungssignale werden dabei abwechselnd von dem einen und dem anderen Dipol gesendet.Out JP 2008 237528 A For example, a remote control device for radio remote control of a model is known. This has an antenna device comprising two mutually V-shaped dipole antennas. The control signals output via the antenna device are alternately transmitted by the one and the other dipole.

Nachteilig an der bekannten Fernsteuerungsvorrichtung ist, dass die hierin verwendeten Dipol-Antennen beispielsweise durch die beiden abstehenden Antennenteile und die notwendige Verbindung zwischen den Antennenteilen mit der Elektronik einen relativ hohen Montageaufwand und relativ hohe Herstellungskosten verursacht.A disadvantage of the known remote control device is that the dipole antennas used here, for example, caused by the two projecting antenna parts and the necessary connection between the antenna parts with the electronics a relatively high installation costs and relatively high production costs.

Die Aufgabe der Erfindung ist es, bei einer gattungsgemäßen Fernsteuerungsvorrichtung die genannten Nachteile zu vermeiden und die Herstellungskosten zu vermindern.The object of the invention is to avoid the disadvantages mentioned in a generic remote control device and to reduce the manufacturing cost.

Diese Aufgabe wird durch eine Fernsteuerungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Dabei sind die Antennenteile auf der Leiterplatte ausgebildet. Hierdurch kann die Antenne als integrierter Bestandteil der Leiterplatte ausgebildet werden, wodurch der für die Antenne anfallende Montageaufwand und die Herstellungskosten der Fernsteuerungsvorrichtung insgesamt reduziert werden können.This object is achieved by a remote control device having the features of claim 1. The antenna parts are formed on the circuit board. As a result, the antenna can be formed as an integral part of the circuit board, whereby the assembly costs incurred for the antenna and the manufacturing cost of the remote control device can be reduced overall.

In einer besonders vorteilhaften Ausführungsform sind die Antennenteile als Leiterbahnen der Leiterplatte ausgebildet. Auf diese Weise können die Material- und Herstellungskosten für die Antenne auf ein Minimum reduziert werden.In a particularly advantageous embodiment, the antenna parts are formed as conductor tracks of the printed circuit board. In this way, the material and manufacturing costs for the antenna can be reduced to a minimum.

Dabei ist es günstig, wenn die Antenneneinrichtung eine direkte Verbindung mit einem Transceiver aufweist und insbesondere auf die Zwischenschaltung eines Verstärkerelementes verzichtet. Durch diesen Verzicht auf ein Verstärkerelement, der durch den geringeren Energiebedarf der als Richtantenne ausgelegten Antenneneinrichtung ermöglicht wird, können die Herstellungskosten der Fernsteuerungsvorrichtung noch weiter reduziert werden.It is advantageous if the antenna device has a direct connection to a transceiver and in particular dispenses with the interposition of an amplifier element. By dispensing with an amplifier element, which is made possible by the lower energy requirement of the designed as a directional antenna device, the manufacturing cost of the remote control device can be further reduced.

Vorteilhafterweise sind die Antenneneinrichtung und der Transceiver gemeinsam auf der Leiterplatte angeordnet, wodurch beide Elemente als bauliche Einheit vormoniert und in der Endmontage der Fernsteuerungsvorrichtung gemeinsam gehandhabt werden können.Advantageously, the antenna device and the transceiver are arranged together on the circuit board, whereby both elements can be pre-assembled as a structural unit and handled together in the final assembly of the remote control device.

Zudem ist es günstig, wenn die Antenneneinrichtung ein strahlendes Element in Form eines Dipols aufweist. Hierdurch kann mit einfachen Mitteln eine geeignete Richtwirkung der Antenneneinrichtung erzielt werden.In addition, it is favorable if the antenna device has a radiating element in the form of a dipole. This can be achieved by simple means a suitable directivity of the antenna device.

Vorteilhafterweise ist der Dipol Teil einer Yagi-Uda-Antenne, wodurch die Richtwirkung der Antenneneinrichtung weiter gesteigert werden kann.Advantageously, the dipole is part of a Yagi-Uda antenna, whereby the directivity of the antenna device can be further increased.

Ferner ist es günstig, wenn die Yagi-Uda-Antenne einen Reflektor aufweist, der als Leiterbahn der Leiterplatte ausgebildet ist. Der Reflektor ist dabei bezüglich des Dipols rückseitig angeordnet, das heißt an einer im Betrieb dem Benutzer B zugewandten Seite des Dipols. Auf diese Weise ist die Yagi-Uda-Antenne einschließlich Reflektor durch eine Anordnung von Leiterbahnen der Leiterplatte gebildet und kann dadurch kostengünstig hergestellt werden.Furthermore, it is favorable if the Yagi-Uda antenna has a reflector which is designed as a conductor track of the printed circuit board. The reflector is arranged at the rear side with respect to the dipole, that is to say at a side of the dipole facing the user B during operation. In this way, the Yagi-Uda antenna including the reflector is formed by an arrangement of conductor tracks of the printed circuit board and can thereby be produced inexpensively.

Zudem ist es alternativ oder zusätzlich hierzu vorteilhaft, wenn die Yagi-Uda-Antenne einen Direktor aufweist, der als Leiterbahn der Leiterplatte ausgebildet ist. Der Direktor ist dabei bezüglich des Dipols vorderseitig angeordnet, das heißt an einer im Betrieb vom Benutzer B abgewandten Seite des Dipols. Auf diese Weise ist die gesamte Yagi-Uda-Antenne durch eine Anordnung von Leiterbahnen der Leiterplatte gebildet und kann dadurch auch einschließlich Direktor besonders kostengünstig hergestellt werden.In addition, it is advantageous as an alternative or in addition to this, if the Yagi-Uda antenna has a director which is designed as a conductor track of the printed circuit board. The director is arranged on the front side with respect to the dipole, that is to say on a side of the dipole facing away from the user B during operation. In this way, the entire Yagi-Uda antenna is formed by an arrangement of conductor tracks of the printed circuit board and can therefore be produced particularly cost-effectively, including the director.

In den Figuren ist eine beispielhafte Ausführungsform der Erfindung dargestellt. Es zeigen:

Figur 2
eine schematische Darstellung einer Richtcharakteristik der Fernsteuerungsvorrichtung nach Fig. 1.
In the figures, an exemplary embodiment of the invention is shown. Show it:
FIG. 1
a circuit diagram of a remote control device according to the invention and
FIG. 2
a schematic representation of a directional characteristic of the remote control device according to Fig. 1 ,

Fig. 1 zeigt eine Fernsteuerungsvorrichtung 2 zur Steuerung eines nicht dargestellten Modells, wie insbesondere eines Flug-, Fahrzeug-, und/oder Schiffsmodells, über zwei Steuerhebel 4. Die Fernsteuerungsvorrichtung 2 weist hierzu ein Gehäuse 6 auf, in dem eine Elektronik 8 untergebracht ist, die mindestens eine Leiterplatte 10 umfasst. Fig. 1 shows a remote control device 2 for controlling a model, not shown, in particular a flight, vehicle, and / or ship model, via two control lever 4. The remote control device 2 has for this purpose a housing 6, in which an electronics 8 is housed, at least a printed circuit board 10 comprises.

Auf der Leiterplatte 10 ist dabei eine Antenneneinrichtung 12 vorgesehen, die sich aus mehreren Antennenteilen zusammensetzt, die eine Yagi-Uda-Antenne bilden. Die Antenneneinrichtung 12 weist hierzu ein strahlendes Element 16 in Form eines Dipols auf, das zwischen einem rückseitigen Reflektor 18 und einem vorderseitigen Direktor 20 angeordnet ist.On the printed circuit board 10, an antenna device 12 is provided, which is composed of a plurality of antenna parts, which form a Yagi-Uda antenna. For this purpose, the antenna device 12 has a radiating element 16 in the form of a dipole, which is arranged between a rear-side reflector 18 and a front-side director 20.

Alle Antennenteile der Antenneeinrichtung 12 sind dabei durch Leiterbahnen LBa, LBb, LBc gebildet, die auf der Leiterplatte 10 ausgeformt sind. Zudem ist auch ein Transceiver 22 auf der Leiterplatte 10 vorgesehen, der direkt, das heißt insbesondere ohne Zwischenschaltung eines Verstärkerelementes, mit der Antenneneinrichtung 12 verbunden ist.All antenna parts of the antenna device 12 are formed by conductor tracks LBa, LBb, LBc, which are formed on the circuit board 10. In addition, a transceiver 22 is also provided on the printed circuit board 10, which is connected directly, that is to say in particular without the interposition of an amplifier element, with the antenna device 12.

Durch die Anordnung dieser Leiterbahnen LBa, LBb, LBc in der Art einer Yagi-Uda-Antenne weist die Antenneneinrichtung 12 eine ausgeprägte Richtcharakteristik auf, wie sie in Fig. 2 durch strichpunktierte Linien dargestellt ist. Wie hieraus zu entnehmen ist, bewirkt diese im Betrieb eine Energieabstrahlung E, die bezüglich eines Benutzers B im Wesentlichen von dessen Vorderseite weg gerichtet ist, während nur sehr wenig Energie von dessen Rückseite weg gerichtet ist. Hierdurch ist der Energieverbrauch der Fernsteuerungsvorrichtung 2 generell sehr gering und ermöglicht insbesondere den Verzicht auf einen Verstärker zwischen Transceiver 22 und der Antenneneinrichtung 12.Due to the arrangement of these interconnects LBa, LBb, LBc in the manner of a Yagi-Uda antenna, the antenna device 12 has a pronounced directional characteristic, as in Fig. 2 is shown by dash-dotted lines. As can be seen from this, in operation, this causes an energy dissipation E, which is directed with respect to a user B substantially away from the front, while only very little energy is directed away from the back. As a result, the power consumption of the remote control device 2 is generally very low, and in particular makes it possible to dispense with an amplifier between the transceiver 22 and the antenna device 12.
