Description

Die Erfindung betrifft ein Tachometeranzeigeelement für Kraftfahrzeuge mit einem Ziffernblatt und mit Leuchtelementen, die auf der Rückseite des Ziffernblatts auf einer Leiterplatte befestigt sind. The invention relates to a speedometer display element for motor vehicles a clock face and with light elements on the back of the Dial are attached to a circuit board.

Herkömmliche Tachometeranzeigeelemente für Kraftfahrzeuge haben ein im wesentlichen lichtundurchlässig beschichtetes Tacho-Ziffernblatt, auf dem bogenförmig Markierungen für Geschwindigkeiten angebracht sind. Die Geschwindigkeit selbst wird durch einen mit einem Schrittmotor verschwenkten Zeiger angezeigt. Der Schrittmotor ist hierbei auf eine Leiterplatte montiert, die im Abstand zu dem Ziffernblatt angebracht ist. Conventional tachometer display elements for motor vehicles have an im essential opaque coated speedometer dial on which arcuate markings for speeds are attached. The Speed itself is achieved by using a stepper motor swiveled pointer appears. The stepper motor is on one Printed circuit board mounted, which is spaced from the dial.

Insbesondere im Bereich der Geschwindigkeitsmarkierungen ist das Ziffernblatt lichtdurchlässig und es ist mindestens ein Leuchtelement auf der Leiterplatte vorgesehen, um eine Hintergrundbeleuchtung des Ziffernblatts zu schaffen. This is particularly true in the area of speed markings Dial translucent and there is at least one light element on the circuit board provided to backlight the Create clock face.

Um eine vorgewählte Geschwindigkeit einer Geschwindigkeitsregelungseinheit, auch Tempomat genannt, darzustellen, sind herkömmlicherweise Leuchtdioden auf die Leiterplatte gelötet. Das Licht wird dann mittels Lichtleiter und Lichtschacht von den Leuchtdioden auf der Leiterplattenebene zum Ziffernblatt geführt. Nachteilig müssen die Abstände der Leuchtpunkte relativ groß sein, um ein Überstrahlen zu vermeiden. At a preselected speed one Speed control unit, also called cruise control, are conventional LEDs are soldered to the circuit board. The light is then turned on Light guide and light well from the LEDs on the PCB level led to the clock face. The distances between the Illuminated dots must be relatively large to avoid overexposure.

Aufgabe der Erfindung war es daher, ein verbessertes Tachometeranzeigeelement zu schaffen, bei dem Leuchtpunkte mit geringerem Abstand voneinander angezeigt werden, ohne dass das Licht auf andere Leuchtpunkte überstrahlt. Insbesondere sollten verschiedenfarbige Leuchtpunkte möglichst nah nebeneinander darstellbar sein. The object of the invention was therefore to provide an improved To create a speedometer display element with the illuminated dots appear closer to each other without the light overlaid on other luminous dots. In particular, should different colored light dots can be displayed as close as possible to each other his.

Die Aufgabe wird mit dem gattungsgemäßen Tachometeranzeigeelement dadurch gelöst, dass

  • - in der Leiterplatte Durchtrittsöffnungen sind,
  • - die Leiterplatte mit ihrer Vorderseite angrenzend an das Ziffernblatt angeordnet ist, und
  • - die Leuchtelemente an der Rückseite der Leiterplatte so angeordnet sind, dass ein Leuchtelement jeweils durch eine Durchtrittsöffnung das Ziffernblatt beleuchtet.
The task is solved with the generic tachometer display element in that
  • - there are openings in the circuit board,
  • - The circuit board is arranged with its front side adjacent to the clock face, and
  • - The lighting elements on the back of the circuit board are arranged so that a lighting element illuminates the dial through a passage opening.

Es wird somit vorgeschlagen, eine Leiterplatte unmittelbar angrenzend hinter dem Ziffernblatt anzuordnen. Die Durchtrittsöffnungen in der Leiterplatte gewährleisten, dass Leuchtpunkte relativ nah nebeneinander angeordnet werden können, ohne dass ein Überstrahlen erfolgt. Hierbei sind die Leuchtelemente so auf der Leiterplatte angebracht, dass jeweils ein Leuchtelement durch eine Durchtrittsöffnung hindurchstrahlt und das Ziffernblatt beleuchtet. It is therefore proposed to have a circuit board immediately adjacent to be placed behind the clock face. The openings in the Printed circuit boards ensure that luminous dots are relatively close together can be arranged without overexposure. Here are the lighting elements attached to the circuit board so that one Illuminating element shines through a passage opening and that Illuminated dial.

Als Leuchtelemente sind vorzugsweise Leuchtdioden vorgesehen. Insbesondere geeignet sind Leuchtdioden mit einem Reverse-Gullwing- Gehäuse, die bündig auf der Rückseite der Leiterplatte aufgelegt werden und deren Anschlussbeine zur Verdrahtung seitlich aus dem Gehäuse der Leuchtdiode herausragen und zur Rückseite der Leiterplatte geführt und dort verlötet werden. Light-emitting diodes are preferably provided as lighting elements. Light-emitting diodes with a reverse gullwing are particularly suitable. Housing that is placed flush on the back of the circuit board and their connecting legs for wiring from the side of the housing Protrude LED and led to the back of the circuit board and be soldered there.

Besonders vorteilhaft ist es, wenn die Linse der Leuchtdiode in die Durchtrittsöffnung der Leiterplatte hineinragt. It when the lens of the light emitting diode in the Passage opening of the circuit board protrudes.

Das Ziffernblatt ist vorzugsweise wie herkömmlich lichtundurchlässig beschichtet. Mindestens im Bereich der Durchtrittsöffnungen der Leiterplatte ist das Ziffernblatt hingegen lichtdurchlässig und vorzugsweise zur Farbgebung eingefärbt. The dial is preferably opaque as conventional coated. At least in the area of the passage openings of the Printed circuit board, however, the dial is translucent and preferred colored for coloring.

Weiterhin ist es vorteilhaft, wenn die Leiterplatte bogenförmig ist und lediglich ein kreisbogenförmiges Segment des Ziffernblatts abdeckt. It is also advantageous if the circuit board is arcuate and only covers an arcuate segment of the clock face.

Die Leuchtelemente dienen vorzugsweise zur Anzeige einer vorgewählten Geschwindigkeit und sind an eine Geschwindigkeitsregelungseinheit, auch Tempomat genannt, angeschlossen. The lighting elements are preferably used to display a preselected one Speed and are at a speed control unit, too Called cruise control, connected.

Die Erfindung wird nachfolgend anhand der beigefügten Zeichnungen näher erläutert. Es zeigen: The invention will now be described with reference to the accompanying drawings explained. Show it:

Fig. 1 Seiten-Schnittansicht des erfindungsgemäßen Tachometer-Anzeigeelementes; Fig. 1 side sectional view of the tachometer display element according to the invention;

Fig. 2 Draufsicht auf einen Ausschnitt des Ziffernblatts des Tachometeranzeigeelementes. Fig. 2 top view of a section of the dial of the speedometer display element.

Die Fig. 1 lässt ein Tachometeranzeigeelement 1 in der seitlichen Schnittansicht erkennen. Das Tachometeranzeigeelement 1 hat in herkömmlicherweise ein Ziffernblatt 2 mit Markierungen unter anderem für die Geschwindigkeitsanzeige. Ein von einem Schrittmotor 3 angesteuerter Zeiger 4 dient zur Geschwindigkeitsanzeige. Der Schrittmotor 3 ist auf eine Leiterplatte 5 montiert, die im Abstand zu dem Ziffernblatt 2 angeordnet ist. Zwischen der Leiterplatte 5 und dem Ziffernblatt 2 befindet sich mindestens ein Kunststoffträger 6, der den Bauraum zwischen Leiterplatte 5 und Ziffernblatt 2 definiert. Figs. 1 reveals a speedometer display element 1 in the side sectional view. The speedometer display element 1 conventionally has a dial 2 with markings, among other things, for the speed display. A pointer 4 controlled by a stepper motor 3 serves to display the speed. The stepper motor 3 is mounted on a circuit board 5 , which is arranged at a distance from the clock face 2 . Between the circuit board 5 and the dial 2 is at least one plastic support 6, which defines the space between printed circuit board 5 and dial. 2

Zur Darstellung einer vorgewählten Geschwindigkeit, d. h. zur Anzeige der Tempomatfunktion eines Kraftfahrzeugs, sind eine Vielzahl von Leuchtdioden 7 vorgesehen, die auf einer bogenförmigen Leiterplatte 8 montiert und verdrahtet sind. Die bogenförmige Leiterplatte 8 ist mit ihrer Vorderseite unmittelbar angrenzend an die Rückseite des Ziffernblatts 2 angebracht. To display a preselected speed, ie to indicate the cruise control function of a motor vehicle, a large number of light-emitting diodes 7 are provided, which are mounted and wired on an arc-shaped printed circuit board 8 . The arcuate printed circuit board 8 is attached with its front side directly adjacent to the rear side of the dial 2 .

Die Fig. 2 lässt eine Draufsicht auf einen Ausschnitt des Ziffernblatts 2 mit Geschwindigkeitsmarkierungen erkennen. Es ist weiterhin die direkt unterhalb des Ziffernblatts 2 angeordnete bogenförmige Leiterplatte 8 mit den aufgelöteten Leuchtdioden 7 skizziert, die im geringen Abstand voneinander entsprechend der Skalen der Geschwindigkeitsmarkierungen angebracht sind. Die von den Leuchtdioden 7 erzeugten Leuchtpunkte sind entsprechend der Tachometer-Skalen im Umkreis in 2,5 Km Markierungsschritten angeordnet. Es sind zwei farbige Leuchtdioden eingesetzt. Diese können je nachdem zwischen rot und grün oder rot und gelb umgeschaltet werden. Somit kann jeder Leuchtpunkt entweder tot oder grün bzw. gelb leuchten. Das Ziffernblatt ist im Bereich der Leuchtpunkte entsprechend lichtdurchlässig. Der Abstand der Leuchtpunkte liegt in einem Raster von etwa 4 mm, so dass der Zwischenstand zwischen den etwa 2,8 mm breiten Leuchtdioden etwa 1,2 mm beträgt. The Fig. 2 can be seen with the speed marks a plan view of a detail of the dial 2. Furthermore, the arc-shaped printed circuit board 8 with the soldered-on light-emitting diodes 7 , which is arranged directly below the dial 2 , is sketched, which are arranged at a short distance from one another in accordance with the scales of the speed markings. The luminous points generated by the light-emitting diodes 7 are arranged in accordance with the tachometer scales in the vicinity in 2.5 km marking steps. Two colored light-emitting diodes are used. These can be switched between red and green or red and yellow depending on the situation. This means that each red dot can either light up dead or green or yellow. The dial is translucent in the area of the luminous dots. The spacing of the luminous dots lies in a grid of approximately 4 mm, so that the intermediate distance between the approximately 2.8 mm wide light-emitting diodes is approximately 1.2 mm.

Wie aus der Fig. 1 erkennbar ist, wird ein Überstrahlen zwischen den Leuchtdioden 7 bei einem solch geringen Zwischenstand verhindert, indem Durchtrittsöffnungen 9 in der bogenförmigen Leiterplatte 8 vorgesehen sind. Die Leuchtdioden 7 sind auf der Rückseite der bogenförmigen Leiterplatte 8 so angeordnet, dass eine Leuchtdiode 7 jeweils durch eine Durchtrittsöffnung 9 hindurchstrahlt und das Ziffernblatt 2 beleuchtet. As can be seen from FIG. 1, overexposure between the light-emitting diodes 7 is prevented at such a low intermediate level by providing through openings 9 in the arcuate printed circuit board 8 . The light-emitting diodes 7 are arranged on the back of the arc-shaped printed circuit board 8 in such a way that a light-emitting diode 7 shines through a passage opening 9 and illuminates the dial 2 .

Vorzugsweise haben die Leuchtdioden 7 Linsen, die in die Durchtrittsöffnungen 9 der bogenförmigen Leiterplatte 8 hineinragen. Die Linsen können auch entsprechend der Durchtrittsöffnung 9 Zylinder sein, die in die Durchtrittsöffnungen 9 gesteckt werden. The light-emitting diodes 7 preferably have lenses which protrude into the passage openings 9 of the arcuate printed circuit board 8 . The lenses can also be cylinders corresponding to the passage opening 9 , which are inserted into the passage openings 9 .

Die Leuchtdioden 7 haben ein Reverse-Gullwing-Gehäuse, das so beschaffen ist, dass die Anschlussbeine ebenso wie die Linse der Leuchtdiode 7 in Richtung der Rückseite der bogenförmigen Leiterplatte 8 weisen. Die Anschlussbeine können auf diese Weise auf der Rückseite der bogenförmigen Leiterplatte 8 verlötet werden. The light-emitting diodes 7 have a reverse gullwing housing, which is designed in such a way that the connection legs, like the lens of the light-emitting diode 7, point in the direction of the rear of the arcuate printed circuit board 8 . In this way, the connection legs can be soldered to the back of the arc-shaped printed circuit board 8 .

Durch eine derartige bogenförmige Leiterplatte 8 mit Durchtrittsöffnungen 9 und mit diesen Durchtrittsöffnungen 9 zusammenwirkenden Leuchtdioden 7 wird das Licht von einem Leuchtpunkt zum anderen bei geringstem Abstand zuverlässig abgeschirmt, ohne dass zusätzliche Lichtleitelemente oder Lichtschächte erforderlich sind. Die Farbgebung kann durch Wahl der Leuchtdioden oder durch Einfärbung des Ziffernblatts im Bereich der Leuchtpunkte erfolgen. Such an arc-shaped printed circuit board 8 with passage openings 9 and light-emitting diodes 7 cooperating with these passage openings 9 reliably shields the light from one luminous point to another at the smallest distance, without additional light-guiding elements or light wells being required. The coloring can be done by choosing the LEDs or by coloring the dial in the area of the luminous dots.
