Abstract
Description
Die Erfindung betrifft ein Stellrad mit mechanischen Kopplungseinrichtungen zur Herstellung einer Wirkverbindung mit einem mechanischen Funktionselement und/oder einem elektrischen Steuerelement mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a setting wheel with mechanical coupling devices for producing an operative connection with a mechanical functional element and / or an electrical control with the features of Preamble of claim 1.
Zum
Ansteuern von Lüftungsdüsen, Klimaanlagen,
Scheinwerfern und dgl. sind beleuchtete Stellräder bekannt. Die Dokumente
Den bekannten Stellrädern ist gemeinsam, dass die Ausleuchtung der Lichtaustrittsflächen gering ist im Vergleich zu der Leistungsaufnahme der Lichtquelle.The known adjusting wheels is common that the illumination of the light exit surfaces low is compared to the power consumption of the light source.
Der Erfindung liegt daher die Aufgabe zugrunde, die Ausleuchtung der Lichtaustrittsfläche zu verbessern.Of the Invention is therefore the object of the illumination of the Light-emitting surface to improve.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. So sieht die Erfindung vor, dass zwischen der Lichtquelle und der Lichtaustrittsfläche ein Lichtleiter angeordnet ist. Dabei ist der Begriff des Lichtleiters dahingehend zu verstehen, dass das von der Lichtquelle emittierte Licht zu einem großen Teil zu den Lichtaustrittsflächen geführt wird. Man könnte insofern auch von einer Bündelung der Lichtstrahlen in Richtung der Lichtaustrittsflächen sprechen. Während beim bekannten Stand der Technik ein Großteil der emittierten Lichtenergie durch Absorption an den im Verhältnis zu den Lichtaustrittsflächen großen Innenflächen der des Stellrads verloren gehen, werden diese Art der Verluste bei dem erfindungsgemäßen Stellrad zumindest erheblich reduziert.These The object is achieved by the Characteristics of claim 1 solved. Thus, the invention provides that between the light source and the light exit surface Optical fiber is arranged. Here is the concept of the light guide to understand that the light emitted by the light source to a big one Part of the light exit surfaces guided becomes. You could in this respect also of a bundling the light beams speak in the direction of the light exit surfaces. While in the known state of the art, a large part of the emitted light energy by absorption at the ratio to the light exit surfaces huge Inner surfaces of the of the adjusting wheel are lost, this type of losses at least the adjusting wheel according to the invention considerably reduced.
Vorzugsweise grenzt der Lichtleiter zur Minimierung derartiger Verluste unmittelbar an die Lichtquelle an und bildet selbst die Lichtaustrittsflächen. Hierdurch werden Verluste, beispielsweise an einer Übergangsstelle zwischen dem Lichtleiter und einer Lichtaustrittsfläche in Form einer Folie oder dgl. vermieden. Weiterhin gewährleistet dies einen einfachen Aufbau. Die Erfindung schließt jedoch nicht aus, dass die Lichtaustrittsflächen von einem separaten Bauteil gebildet werden.Preferably the light guide immediately adjoins to minimize such losses to the light source and forms even the light exit surfaces. hereby losses, for example, at a transition point between the Light guide and a light exit surface in the form of a film or Like. avoided. Continue to be guaranteed this is a simple structure. However, the invention includes Do not rule out that the light exit surfaces of a separate component be formed.
Um eine im Wesentlichen gleichmäßige Ausleuchtung über den gesamten Umfang des Stellrads zu gewährleisten, ist die Lichtquelle vorzugsweise mittig im Stellrad angeordnet. Dabei ist mit „mittig" gemeint, dass sich die Lichtquelle auf der Drehachse des Stellrads befindet. In machen Fällen kann jedoch auch gewünscht sein, dass eine für den Umfang ungleichmäßige Ausleuchtung erfolgt, beispielsweise um ein bestimmtes Anzeigesymbol hervorzuheben. In diesem Fall sollte die Lichtquelle außermittig angeordnet werden.Around a substantially uniform illumination over the To ensure the entire circumference of the setting wheel is the light source preferably arranged centrally in the setting wheel. It means "centered" that the light source is located on the axis of rotation of the setting wheel. In doing make but also desired be that one for the scope uneven illumination takes place, for example to highlight a particular display icon. In In this case, the light source should be arranged off-center.
Die oben genannte Bündelung der Lichtstrahlen wird vorzugsweise dadurch erreicht, dass der Lichtleiter eine Spitze aufweist, die in Richtung der Lichtaustrittsfläche weist. Lichtstrahlen, die winkelig versetzt zur Lichtaustrittsfläche von der Lichtquelle emittiert werden, werden so an der Innenfläche dieser Spitzen reflektiert und in Richtung der Lichtaustrittsflächen umgelenkt.The above bundling the light rays are preferably achieved by the light guide has a tip facing in the direction of the light exit surface. Light rays, the angular offset to the light exit surface of the light source are emitted, so on the inner surface of this Tips reflected and deflected in the direction of the light exit surfaces.
Vorzugsweise besteht der Lichtleiter aus einem glasklaren Kunststoff. Dieser gewährleistet eine einfache Verarbeitbarkeit, einen günstigen Preis sowie gute Reflektionseigenschaften.Preferably The light guide is made of a clear plastic. This guaranteed a simple processability, a low price and good reflection properties.
Entgegen dem bekannten Stand der Technik schlägt die Erfindung vor, die Zahl der zu montierenden Bauteile dadurch zu reduzieren, dass das Stellrad einen lichtundurchlässigen Trägerkörper aufweist und dass der Trägerkörper und der Lichtleiter einstückig im Zweikomponenten-Spritzguss hergestellt sind. Dies hat den Vorteil, dass lediglich noch die Lichtquelle zugefügt und der Trägerkörper in eine Lagerstelle des Stellrads eingefügt werden muss.opposite In the known art, the invention proposes the number To reduce the components to be assembled by the fact that the wheel an opaque Carrier body has and that the carrier body and the light guide in one piece produced in two-component injection molding. This has the advantage that only added to the light source and the carrier body in a bearing point of the setting wheel must be inserted.
Häufig wird zur Verbesserung der haptischen Eigenschaften eine weiche Außenhaut bei derartigen Stellrädern vorgesehen. Für diesen Fall schlägt die Erfindung vor, dass der Trägerkörper, der Lichtleiter und die Außenhaut einstückig im Dreikomponenten-Spritzguss hergestellt werden. Dies reduziert wie oben beschrieben den Montageaufwand.Frequently becomes To improve the haptic properties of a soft outer skin in such adjusting wheels intended. For this case strikes the invention in that the carrier body, the Optical fiber and the outer skin one piece in three-component injection molding getting produced. This reduces the installation effort as described above.
Vorzugsweise ist die Lichtquelle drehfest mit der Lagerstelle des Stellrads verbunden, d. h. sie dreht sich bei der Bedienung des Stellrads nicht mit. Dadurch wird vermieden, dass die Zuleitungen laufend gebogen oder tordiert werden.Preferably the light source is rotatably connected to the bearing point of the setting wheel, d. H. it does not turn when operating the setting wheel. Thereby it is avoided that the leads continuously bent or twisted become.
Als Lichtquelle schlägt die Erfindung die Verwendung einer LED vor, wobei grundsätzlich auch andere Lichtquellen, wie z. B. Glühlampen denkbar sind. Auch kann die Lichtquelle wiederum lediglich eine Lichtaustrittsfläche eines Lichtleiters sein, wenn beispielsweise die LED entfernt von dem Stellrad angeordnet werden soll. In diesem Fall würde das Licht ausgehend von der LED mittels eines Lichtleiters beispielsweise in die Mitte des Stellrades geleitet werden und von dort mittels des erfindungsgemäßen Lichtleiters innerhalb des Stellrades bis zu den Lichtaustrittsflächen.As the light source, the invention proposes the Ver use of an LED before, in principle, other light sources such. B. incandescent lamps are conceivable. Also, the light source may in turn be only a light exit surface of a light guide, for example, if the LED is to be located away from the setting wheel. In this case, the light would be led starting from the LED by means of a light guide, for example, in the middle of the setting wheel and from there by means of the light guide according to the invention within the setting wheel to the light exit surfaces.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The Invention will now be described with reference to a drawing embodiment explained in more detail.
