Description

Anzeigeinstrument Gauge
Die Erfindung betrifft ein Anzeigeinstrument, insbesondere zur Verwendung im automobilen Bereich.The invention relates to a display instrument, in particular for use in the automotive sector.
.Analog arbeitende Kraftfahrzeug-Anzeigeinstrumente mit einem feststehenden runden Ziffernblatt, das randseitig mit einer Skala für die anzuzeigende Messgröße versehen ist und einem relativ zur Skala drehbar gelagerten Zeiger, der abhängig von dem gegenwärtige Wert der Messgröße auf eine entsprechende Steile der Skala zeigt, sind in zahlreichen Konstruktionsvarianten am Markt vorhanden. Aus der Druckschrift JP 2006 214990 A ist eine Anzeigevorrichtung bekannt, bei der ein drehbarer Zeiger und eine Drehbare Skala vorgesehen ist.Analog motor vehicle display instruments with a fixed round dial, which is provided at the edge with a scale for the measured variable to be displayed and a relative to the scale rotatably mounted pointer, which depends on the current value of the measured variable to a corresponding portion of the scale, are in numerous design variants available on the market. From document JP 2006 214990 A a display device is known in which a rotatable pointer and a rotatable scale is provided.
Nachteilig bei bekannten Anzeigeinstrumenten ist, dass jedenfalls immer ein zentral angeordneter drehbarer Zeiger vorhanden ist, für den zentral angeordnet ein Antrieb vorgesehen sein muss.A disadvantage of known indicating instruments is that in any case always a centrally arranged rotatable pointer is provided for the centrally arranged a drive must be provided.
Der Erfindung liegt daher die Aufgabe zugrunde, ein flexibel einsetzbares Anzeigeinstrument zu schaffen, das ohne einen zentralen Zeiger und insbesondere ohne einen zentralen beweglichen und angetriebenen Zeiger auskommt und dennoch eine stabile, lebensdauerstabile, einfach ablesbare, intuitiv verständliche und kostengünstig herstellbare Anzeigemöglichkeit schafft.The invention is therefore an object of the invention to provide a flexible display instrument that manages without a central pointer and in particular without a central movable and driven pointer and yet creates a stable, durable, easy to read, intuitive and affordable to produce display option.
Die Aufgabe wird gelöst durch ein Anzeigeinstrument, insbesondere für Kraftfahrzeuge, mit einem Zeiger und mit einer Skalenanzeige, wobei die Relativposition zwischen dem Zeiger und der Skalenanzeige zur Anzeige einer Messinformation oder zur Anzeige einer vorgegebenen Information vorgesehen ist, dadurch gekennzeichnet, dass der Zeiger feststehend vorgesehen ist und die Skalenanzeige mechanisch beweglich ist, insbesondere drehbeweglich vorgesehen ist. Bei dem erfindungsgemäßen Anzeigeinstrument wird daher durch die Stellung eines mit einer Skala versehenen Skalenträgers relativ zu einem (feststehenden) Zeiger der aktuelle Wert der anzuzeigenden Größe angezeigt. Dabei ist der Zeiger stationär, während der Skalenträger relativ zum Zeiger drehbar gelagert ist. Gemäß einer Ausgestaltung der Erfindung ist der Skalenträger mit einem zentralen Durchbruch versehen, beispielsweise ringförmig oder ringsegmentförmig ausgebildet, und in Umfangrichtung beweglich dezentral gelagert. Hierdurch ist es erfindungsgemäß vorteilhaft möglich, dass ein besonders einfacher, flacher und kostengünstiger Aufbau des Anzeigeinstruments möglich ist.The object is achieved by a display instrument, in particular for motor vehicles, with a pointer and with a scale display, wherein the relative position between the pointer and the scale display is provided for displaying a measurement information or for displaying a predetermined information, characterized in that the pointer provided fixed is and the scale display is mechanically movable, in particular rotatably provided. In the display instrument according to the invention, the current value of the variable to be displayed is therefore indicated by the position of a graduated scale carrier relative to a (fixed) pointer. In this case, the pointer is stationary, while the scale carrier is rotatably mounted relative to the pointer. According to one embodiment of the invention, the scale carrier is provided with a central opening, for example, annular or ring segment-shaped, and mounted movable in the circumferential direction decentralized. This makes it advantageously possible according to the invention that a particularly simple, flat and cost-effective construction of the display instrument is possible.
Erfindungsgemäß ist ferner bevorzugt, dass die Skalenanzeige mittels eines Gleitlagers relativ zum Anzeigeinstrument gelagert vorgesehen ist. Hierdurch ist ein besonders einfacher und kostengünstiger Aufbau möglich.According to the invention it is further preferred that the scale display is provided mounted by means of a sliding bearing relative to the indicating instrument. As a result, a particularly simple and inexpensive construction is possible.
Weiterhin ist es bevorzugt, dass die Skalenanzeige mittels eines Ringzeigers bewegbar vorgesehen ist bzw. dass der Ringzeiger drehfest verbunden einen Zahnkranz aufweist bzw. dass das Anzeigeinstrument einen Schrittmotor aufweist, mittels dessen eine Drehbewegung des Ringzeigers mittels des Zahnkranzes vorgesehen ist. Es kann hierdurch in einfacher Weise eine Bewegung des Ringzeigers bzw. der Skalenanzeige bewirkt werden und der Antrieb eines solchen Ringzeigers platzsparend realisiert werden.Furthermore, it is preferred that the scale display is movably provided by means of a ring pointer or that the ring pointer has a ring gear rotatably connected or that the indicating instrument has a stepping motor, by means of which a rotary movement of the ring pointer is provided by means of the ring gear. It can thereby be effected in a simple manner, a movement of the ring pointer or the scale display and the drive of such a ring pointer can be realized to save space.
Ferner ist es erfindungsgemäß bevorzugt, dass das Anzeigeinstrument einen weiteren Ringzeiger aufweist bzw. dass der weitere Ringzeiger drehfest verbunden einen weiteren Zahnkranz aufweist bzw. dass das Anzeigeinstrument einen weiteren Schrittmotor aufweist, mittels dessen eine Drehbewegung des weiteren Ringzeigers mittels des weiteren Zahnkranzes vorgesehen ist. Es kann hierdurch in einfacher Weise eine Bewegung des weiteren Ringzeigers bewirkt werden und der Antrieb eines solchen weiteren Ringzeigers platzsparend und unabhängig von der Bewegung des Ringerzeigers bzw. der Skalenanzeige realisiert werden.Furthermore, it is preferred according to the invention that the indicating instrument has a further ring pointer or that the further ring pointer has a further toothed ring in a rotationally fixed connection or that the indicating instrument has a further stepping motor, by means of which a rotary movement of the further ring pointer is provided by means of the further toothed ring. It can thereby be effected in a simple manner, a movement of the other ring pointer and the drive of such a further ring pointer space-saving and independent of the movement of the Ringer pointer or the scale display can be realized.

Die Baugruppe 1 weist einen dezentral gelagerten ringförmig oder ringartig ausgestalteten Skalenträger 2 auf, dessen dem Fahrgastraum zugewandte Seite mit einer Skala 3 für die Fahrzeuggeschwindigkeit versehen ist.The assembly 1 has a decentrally mounted annular or ring-like designed scale carrier 2, whose side facing the passenger compartment is provided with a scale 3 for the vehicle speed.
Ein in der Art einer Zeigerfahne ausgebildeter (feststehender) Zeiger 4 ist bezüglich der Fahrzeugkarosserie stationär angeordnet. Der zu seinem freien Ende spitz zulaufende Zeiger 4 erstreckt sich vom Äußeren Rand des Skalenträgers 2 radial nach innen. Der Skalenträger 2 führt abhängig vom gegenwärtigen Wert der Fahrzeuggeschwindigkeit zwischen einer Nullposition und Vollausschlag eine Drehbewegung um eine geometrische Drehachse aus, die erfindungsgemäß beispielsweise mit der geometrischen Ringachse des Skalenträgers 2 zusammenfällt.A (fixed) pointer 4 formed in the manner of a pointer flag is stationary with respect to the vehicle body. The pointing to its free end pointer 4 extends from the outer edge of the scale carrier 2 radially inwardly. The scale carrier 2 executes, depending on the current value of the vehicle speed between a zero position and full deflection, a rotational movement about a geometric axis of rotation, which according to the invention coincides, for example, with the geometric ring axis of the scale carrier 2.
Beispielsweise wird der Skalenträger 2 durch (oder über) einen - für sich alleine betrachtet - an sich bekannten Ringzeiger angetrieben. Der Ringzeiger wird somit einer neuen Verwendung zugeführt, die von seinem ursprünglichen Zweck losgelöst ist.For example, the scale carrier 2 is driven by (or via) a - by itself - known ring pointer. The ring pointer is thus fed to a new use which is detached from its original purpose.
Der in Figur 1 angezeigte erste Wert für die augenblickliche Fahrzeuggeschwindigkeit ist kleiner als der in Figur 2 angezeigte zweite Wert für die augenblickliche Fahrzeuggeschwindigkeit.The first value for the current vehicle speed indicated in FIG. 1 is smaller than the second value for the instantaneous vehicle speed indicated in FIG.
Die Skala 3 bildet ein Kreissegment.The scale 3 forms a circle segment.
Die bezüglich der Skala 3 ortsfeste erste Beschriftung der Skala 3 erfolgt so, dass die Ziffernwerte für die Fahrzeuggeschwindigkeit entlang der Skala 3 im Uhrzeigersinn steigend aufgetragen sind. Dementsprechend hat sich der Skalenträger 2, wie durch den ersten Drehpfeil D1 in Figur 2 angedeutet, ausgehend von der Situation gemäß Figur 1 im Uhrzeigersinn in die Stellung gemäß Figur 2 gedreht.The stationary with respect to the scale 3 first caption of the scale 3 is such that the numerical values for the vehicle speed along the scale 3 in the clockwise direction are increasing. Accordingly, the scale carrier 2, as indicated by the first rotation arrow D1 in FIG. 2, has turned clockwise from the situation according to FIG. 1 into the position according to FIG.
Der in Figur 3 angezeigte dritte Wert für die augenblickliche Fahrzeuggeschwindigkeit ist größer als der zweite Wert für die Fahrzeuggeschwindigkeit. Dementsprechend hat sich der Skalenträger 2, wie durch den zweiten Drehpfeil D2 in Figur 3 angedeutet, ausgehend von der Situation gemäß Figur 2 gegen den Uhrzeigersinn in die Stellung gemäß Figur 3 gedreht.The third value for the instantaneous vehicle speed indicated in FIG. 3 is greater than the second value for the vehicle speed. Accordingly, the scale carrier 2, as indicated by the second rotation arrow D2 in FIG. 3, has turned in the counterclockwise direction into the position according to FIG. 3, starting from the situation according to FIG.
Figur 4 zeigt Komponenten der Baugruppe 1 , in einer während des Betriebs des Anzeigeinstruments eingenommenen räumlichen Relativlage zueinander. Der ringförmige Skalenträger 2 ist auf einem Zahnradritzel 6 angeordnet. Der nur teilweise dargestellte Zeiger 4 ist mit einem rechtwinklig zu letzterem angeordneten Schenkel 5 versehen.FIG. 4 shows components of the assembly 1 in a relative position relative to one another during operation of the indicating instrument. The annular scale carrier 2 is arranged on a gear pinion 6. The only partially illustrated pointer 4 is provided with a right angle to the latter arranged leg 5.
Die Figuren 6 bis 7 zeigen jeweils die gleiche erfindungsgemäß ausgestalte Baugruppe 1 eines beispielsweise in das Armaturenbrett eines Kraftfahrzeugs integrierten Anzeigeinstrumentes gemäß einer zweiten Variante im Zustand der Anzeige jeweils eines unterschiedlichen Wertes für die Fahrzeuggeschwindigkeit, in einer perspektivischen Ansicht von schräg vorne.Figures 6 to 7 respectively show the same inventively ausgestalte assembly 1 of an integrated example in the dashboard of a motor vehicle display instrument according to a second variant in the state of displaying each a different value for the vehicle speed, in a perspective view obliquely from the front.

Die Skala 3 bildet ein zweites Kreissegment.The scale 3 forms a second circle segment.
Die bezüglich der Skala 3 ortsfeste Beschriftung der Skala 3 erfolgt so, dass die Ziffernwerte für die Fahrzeuggeschwindigkeit entlang der Skala 3 im Uhrzeigersinn steigend aufgetragen sind.The stationary with respect to the scale 3 labeling of the scale 3 is carried out so that the numerical values for the vehicle speed along the scale 3 in the clockwise direction are increasing.
Es versteht sich, dass die Ziffemwerte auch im Uhrzeigersinn fallend aufgetragen werden können.It goes without saying that the numerical values can also be plotted in a clockwise direction.
Ein in der Art einer Zeigerfahne ausgebildeter Zeiger 4 ist bezüglich der Fahrzeugkarosserie stationär angeordnet. Der Zeiger 4 erstreckt sich wiederum vom äußeren Rand des Skalenträgeres 2 radial nach innen.A trained in the manner of a pointer flag pointer 4 is stationary with respect to the vehicle body. The pointer 4 in turn extends radially inwardly from the outer edge of the scale carrier 2.

Der ringförmige Skalenträger 2 wird derart relativ zum stillstehenden Zeiger 4 gedreht, dass letzterer stets auf die Stelle der Skala 3 mit dem Ziffernwert für die gegenwärtige Fahrzeuggeschwindigkeit deutet.The annular scale carrier 2 is rotated relative to the stationary pointer 4 so that the latter always to the point of the scale 3 with the digit value for the current vehicle speed indicates.
Die Baugruppe 1 weist ferner einen weiteren Ringzeiger T beispielsweise eines Tempomaten auf.The assembly 1 also has a further ring pointer T, for example, a cruise control.
Der Skalenträger 2 wird durch einen - für sich alleine betrachtet - an sich bekannten Ringzeiger 7 angetrieben.
