Description

» Anzeigeeinrichtung zum Anzeigen von Betriebszuständen»Display device for displaying operating states
Die Erfindung betrifft eine Anzeigeeinrichtung zum Anzeigen von Betriebszuständen mit auf einer Leiterplatte befestigten, elektrisch ansteuerbaren Leuchtelementen, einem Gehäuse und einer mit dem Gehäuse verbindbaren Frontplatte, an welcher den Leuchtelementen zugeordnete, lichtdurchlässige Bereiche ausgebildet sind.The invention relates to a display device for displaying operating states with electrically controllable lighting elements fastened to a printed circuit board, a housing and a front plate which can be connected to the housing and on which the translucent areas assigned to the lighting elements are formed.
Im allgemeinen werden zur Störungsmeldung, zur Anzeige des Erreichens kritischer Betriebszustände oder des Erreichens von Reservewerten von Verbrauchsmedien, jedenfalls für bestimmte Grundfunktionen von Fahrzeugen, Maschinen oder Produktionsanlagen, optische und/oder akustische Signalgeber vorgesehen, die üblicherweise in Frontwänden, in Armaturenbrettern oder Anzeigetableaus zusammen mit Bedien- und anderen Anzeigeeinrichtungen integriert sind.In general, optical and / or acoustic signal generators are provided for malfunction reporting, to indicate that critical operating states have been reached or to reach reserve values for consumables, in any case for certain basic functions of vehicles, machines or production systems, which are usually provided in front walls, in dashboards or display panels together with Operating and other display devices are integrated.
Sollen darüber hinaus zusätzliche und nicht zwingend vorgeschriebene Kontrollmaßnahmen erfolgen und hierfür geeignete Kontrolleinrichtungen und diesen zugeordnete Anzeigemittel installiert werden, bestehen in der Regel, insbesondere bezgl. der Anzeigemittel, erhebliche Anordnungsprobleme, weil die Anordnung der Anzeigemittel in dem relativ eng begrenzten Blickbereich eines Bedienenden bzw. eines Fahrers erfolgen sollte, und in diesem Bereich von vornherein eine Häufung von Instrumenten und Signalanzeigemitteln gegeben ist. Allein dadurch wird die Bereitschaft, zusätzliche Kontrollmaßnahmen durchzuführen, auch wenn deren vorteilhafte Wirkung außer Zweifel steht, erheblich verringert. Um diese Akzeptanzschwellen abzubauen, ist es daher erforderlich, alle Komponenten einesIf additional and not mandatory control measures are to be carried out and suitable control devices and display means assigned to them are to be installed, there are generally considerable arrangement problems, particularly with regard to the display means, because the arrangement of the display means in the relatively narrow viewing area of an operator or a driver should take place, and in this area there is an accumulation of instruments and signal display means from the outset. This alone considerably reduces the willingness to carry out additional control measures, even if there is no doubt that they will have an advantageous effect. To reduce these acceptance thresholds, it is therefore necessary to combine all components
Kontrollsystems, die Geber, die Signalverarbeitungselektronik und die Signalanzeigemittel, so zu gestalten, daß sie durch eine möglichst einfache Herstellung kostengünstig sind, daß die Montage und der spätere Austausch weder Spezialwissen, noch spezielle Vorrichtungen erforderlich machen und daß eine zuverlässige Funktion gewährleistet ist.Control system, the encoder, the signal processing electronics and the signal display means to be designed so that it is as simple as possible manufacture are inexpensive that the assembly and the subsequent exchange require neither special knowledge nor special devices and that a reliable function is guaranteed.
Zur Verwirklichung eines derartigen Konzeptes war der vorliegenden Erfindung die Aufgabe gestellt, eine Anzeigeeinrichtung zum Anzeigen von Betriebszuständen zu schaffen, die sich durch besondere Einfachheit auszeichnet und mit geringem Aufwand, jedoch gut reproduzierbar herstellbar ist, die vielseitig verwendbar ist und weitgehend unabhängig von den räumlichen Gegebenheiten befestigt werden kann.In order to implement such a concept, the object of the present invention was to create a display device for displaying operating states which is characterized by particular simplicity and can be produced with little effort, but is reproducible, can be used in a variety of ways and is largely independent of the spatial conditions can be attached.
Die Lösung der Aufgabe ist dadurch gekennzeichnet, daß das Gehäuse der Anzeigeeinrichtung schalenförmig mit einem Boden und einer umlaufenden Wand ausgebildet ist, daß auf der Schaleninnenseite an dem Boden den Leuchtelementen zugeordnete Lichtkanäle angeformt sind, daß an der Schalenaußenseite an dem Boden eine der Frontplatte zugeordnete Vertiefung ausgebildet ist, daß die Leiterplatte als ein das Gehäuse rückseitig abschließender Deckel dient und daß an der umlaufenden Wand der Leiterplatte zugeordnete Rastmittel ausgebildet sind.The solution to the problem is characterized in that the housing of the display device is cup-shaped with a bottom and a circumferential wall, that light channels assigned to the lighting elements are formed on the inside of the tray on the bottom, that on the outside of the tray on the bottom a depression assigned to the front plate It is formed that the circuit board serves as a cover closing the rear of the housing and that latching means are formed on the peripheral wall of the circuit board.
Weitere vorteilhafte Ausbildungen der erfindungsgemäßen Lösung beschreiben die ünteransprüche.Further advantageous developments of the solution according to the invention are described in the subordinate claims.
Der wesentliche Vorteil der Anzeigeeinrichtung besteht darin, daß sie aus drei auf einfache Weise herstell- und miteinander verbindbaren, letztlich auch eine maschinelle Montage gestattenden Baueinheiten besteht, die leicht austauschbar sind. Vorteilhaft ist ferner, daß die Anzeigeeinrichtung aufgrund ihrer besonders flachen Dimensionierung sowohl auf einer Instrumententafel, einem Armaturenbrett oder dergl. räumlich weitgehend unabhängig anbringbar, als auch fest zugeordnet und vorzugsweise versenkt bzw. bei entsprechender Gehäusegestaltung frontflächenbündig installierbar ist, wobei die Anbringung problemlos auch vom Anwender vorgenommen werden kann und keine Verschraubung erforderlich macht. Ferner läßt sich bei einer maximal sinnvollen Ausbildung von Lichtkanälen in der Gehäuseschale und einer entsprechenden Anzahl von Leuchtelementen auf der Leiterplatte lediglich durch unterschiedliches Bedrucken der Frontplatte die Anzeigeeinrichtung für eine Vielzahl von Anwendungsfällen ausbilden und gegebenenfalls vor Ort dem vorliegenden Anwendungsfall anpassen. So kann die Anzeigeeinrichtung vorgesehen werden, kritische Betriebszustände zwischen Rad und Achse eines Fahrzeuges, beispielsweise bezüglich der Bremsbeläge, der Bremsen und/oder Radlagertemperaturen, der Rad¬ oder Achsbelastungen oder der Reifendrücke, aber auch hinsichtlich der Funktion von Antiblockier- und AntischlupfSystemen anzuzeigen, und zwar bezogen auf die Fahrzeuggeometrie positionsrichtig anzuzeigen. Ebenso ist die Anzeigeeinrichtung verwendbar, um die Arbeitszeitgrenzen, beispielsweise von Fahrer und Beifahrer eines Fahrzeuges zu signalisieren und das Einhalten der vorgeschriebenen Pausen zu erleichtern.The main advantage of the display device consists in the fact that it consists of three structural units which can be produced and connected to one another in a simple manner and ultimately also permit mechanical assembly, and which are easily interchangeable. It is also advantageous that, due to its particularly flat dimensions, the display device can be attached to an instrument panel, a dashboard or the like in a largely spatially independent manner, as well as permanently assigned and preferably recessed or, with a corresponding housing design, can be installed flush with the front surface, the attachment also being easy for the user can be made and no screwing required. Furthermore, with the most sensible design of light channels in the housing shell and a corresponding number of lighting elements on the printed circuit board, the display device can be designed for a large number of use cases only by different printing on the front plate and, if necessary, adapted on site to the present use case. Thus, the display device can be provided to display critical operating states between the wheel and axle of a vehicle, for example with regard to the brake pads, the brakes and / or wheel bearing temperatures, the wheel or axle loads or the tire pressures, but also with regard to the function of anti-lock and anti-slip systems, and to be displayed correctly in relation to the vehicle geometry. The display device can also be used to signal the working time limits, for example of the driver and front passenger of a vehicle, and to facilitate compliance with the prescribed breaks.
Selbstverständlich kann die Anzeigeeinrichtung, wenn entsprechende Steckverbindungen vorgesehen werden, auch ausschließlich als Testgerät, beispielsweise in einer Kraftfahrzeugwerkstatt oder durch einen Fuhrparkkontrolleur, Anwendung finden. Auch ist es denkbar, zur Verdeutlichung des Signaleffektes dauernd oder nach einer bestimmten Zeit das betreffende Leuchtelement intermittierend anzusteuern und/oder ein akustisches Signal zu geben.If appropriate plug connections are provided, the display device can of course also be used exclusively as a test device, for example in a motor vehicle workshop or by a vehicle fleet controller. To clarify the signal effect, it is also conceivable to drive the relevant lighting element intermittently and / or to give an acoustic signal, either continuously or after a certain time.
Erwähnenswert ist ferner, daß die Zugentlastung für das der angestrebten flachen Bauweise verwendete Flachbandkabel unmittelbar in der Leiterplatte integriert ist und daß, indem die Leiterplatte unmittelbar an den Stirnflächen der Lichtkanäle anliegt, der übrige Gehäusere-am nicht zwingend staubdicht ausgebildet sein muß.It is also worth mentioning that the strain relief for the flat cable used for the desired flat design is integrated directly into the printed circuit board and that, since the printed circuit board lies directly against the end faces of the light channels, the rest of the housing does not necessarily have to be dustproof.
Im folgenden sei die Erfindung anhand der Zeichnungen näher erläutert. Es zeigen FIGUR 1 eine Frontansicht der erfindungsgemäßen Anzeigeeinrichtung,The invention is explained in more detail below with reference to the drawings. Show it 1 shows a front view of the display device according to the invention,
FIGUR 2 eine Innen- bzw. Rückansicht des Gehäuses,FIGURE 2 is an inside or rear view of the housing,

FIGUR 5 eine Seitenansicht der beispielsweise an einem Armaturenbrett befestigten Anzeigeeinrichtung.FIGURE 5 is a side view of the display device attached, for example, to a dashboard.
Die Frontansicht gemäß FIGUR 1 zeigt ein Gehäuse 1 mit einer Frontplatte 2, welche als selbstklebende, transparente Folie ausgebildet und mit einer Symbolgrafik für beispielsweise eine Bremsbelagkontrolle bedruckt ist. Die Symbolgrafik zeigt einen Lastzug mit Motorfahrzeug 3 und Anhänger bzw. Sattelauflieger 4 sowie einen Fahrtrichtungspfeil 5 mit einem dreiachsigen Fahrzeug entsprechend sechs den jeweiligen Bremsen zugeordneten, unbedruckten und somit lichtdurchlässigen Bereichen, von denen einer mit 6 bezeichnet ist. Mit 7 ist ein Flachbandkabel bezeichnet, mittels dessen die Anzeigeeinrichtung mit einer der Aufbereitung und Organisation der Gebersignale dienenden Elektronik verknüpft ist.The front view according to FIG. 1 shows a housing 1 with a front plate 2, which is designed as a self-adhesive, transparent film and is printed with a symbol graphic for, for example, a brake pad check. The symbol graphic shows a road train with a motor vehicle 3 and trailer or semi-trailer 4 as well as a direction arrow 5 with a three-axle vehicle corresponding to six unprinted and thus translucent areas assigned to the respective brakes, one of which is designated by 6. 7 designates a ribbon cable, by means of which the display device is linked to electronics used for processing and organizing the encoder signals.
Die FIGUR 2 und der Schnitt des Gehäuses 1 in FIGUR 4 zeigen, daß das Gehäuse 1 schalenförmig ausgebildet ist und im wesentlichen aus einem Boden 8 und einer umlaufenden Wand 9 besteht. An der Wand 9 sind nach innen weisende Rastnasen 10, 11, 12 und 13 angeformt, während am Boden 8 konzentrisch zu Durchgangsδffnungen 14, die entsprechend der Symbolgrafik angeordnet sind, mehrere Ansätze 15 ausgebildet sind. Ferner sind in den Ecken des Gehäuses 1 Stützen 16 vorgesehen, die vorzugsweise mit jeweils einer Sacköffnung 17 versehen sind, um gegebenenfalls die Anzeigeeinrichtung durch Anschrauben befestigen zu können.FIGURE 2 and the section of the housing 1 in FIGURE 4 show that the housing 1 is bowl-shaped and essentially consists of a bottom 8 and a peripheral wall 9. On the wall 9 inwardly facing locking lugs 10, 11, 12 and 13 are formed, while on the bottom 8 concentrically to through openings 14, which are arranged according to the symbol graphic, several approaches 15 are formed. Furthermore, supports 16 are provided in the corners of the housing, which are preferably each provided with a blind opening 17, in order to be able to fasten the display device by screwing on if necessary.
Die FIGUREN 3 und 4 zeigen, daß die Anzeigeeinrichtung rückseitig durch einen Deckel abgeschlossen ist, der durch eine einseitig kaschierte Leiterplatte 18 gebildet wird. Auf der Leiterplatte 18 sind, bezogen auf das Gehäuse 1, nach innen weisende Leuchtdioden - eine ist mit 19 bezeichnet - angebracht und ein nach außen weisendes Hakenband 20 befestigt, das zusammen mit einem selbstklebend anbringbaren Gegenstück 21 einer schraubenlosen Befestigung der Anzeigeeinrichtung dient. Ferner ist ersichtlich, daß in der Leiterplatte 18 zwei parallele Schlitze 22 und 23 angebracht sind, die zusammen mit dem zwischen ihnen verbleibenden Steg 24 eine Spange bilden, die dem um den Steg 24 herumgeführten Flachbandkabel 7 als eine in die Leiterplatte 18 integrierte Zugentlastung dient. Wie der FIGUR 3 anhand der Aderanzahl des Flachbandkabels 7 ferner entnommen werden kann, ist lediglich eine für den Anwendungsfall erforderliche Anzahl von Leuchtdioden vorgesehen und angeschlossen, d. h. es ist gegenüber diesem Anwendungsfall noch eine Erweiterung möglich.FIGURES 3 and 4 show that the display device is closed on the back by a cover which is formed by a circuit board 18 laminated on one side. On the printed circuit board 18, with reference to the housing 1, inward-pointing light-emitting diodes - one is designated by 19 - are attached and an outward-facing hook band 20 is fastened, which together with a self-adhesive counterpart 21 serves for screwless fastening of the display device. It can also be seen that two parallel slots 22 and 23 are formed in the circuit board 18, which together with the web 24 remaining between them form a clasp which serves as a strain relief for the ribbon cable 7 guided around the web 24. As can further be seen from FIG. 3 on the basis of the number of cores of the ribbon cable 7, only a number of light-emitting diodes required for the application is provided and connected, ie an expansion is possible compared to this application.
Aus der FIGUR 4 ist die besonders einfache Montage ersichtlich, d. h. die selbstklebend beschichtete Frontplatte 2 wird in eine im Gehäuse 1 ausgebildete Vertiefung 25 eingelegt und durch Andrücken befestigt; die Leiterplatte 18 wird mit dem Gehäuse verrastet. Dabei stützt sich die Leiterplatte 18 auf den Ansätzen 15 und den Stützen 16, deren Stirnfläche in einer Ebene "a" liegen ab, und die Leuchtdioden 19 ragen in die Durchgangsöffnungen 14, die zusammen mit den Ansätzen 15 Lichtkanäle bilden, hinein. Dadurch wid eine ausreichende Abdichtung gegen Verschmutzung der Leuchtdioden erzielt, auch wenn zwischen der Wand 9 des Gehäuses 1 und der Leiterplatte 18 der Montage wegen relativ viel Spiel vorgesehen werden wird. Die Dichtwirkung kann dadurch noch verbessert werden, daß für das Gehäuse ein Werkstoff mit einem gewissen, elastomeren Effekt verwendet wird und an den Lichtkanälen gegebenenfalls geeignete Dichtlippen angeformt werden.FIG. 4 shows the particularly simple assembly, i. H. the self-adhesive coated front panel 2 is placed in a recess 25 formed in the housing 1 and fastened by pressing; the circuit board 18 is latched to the housing. The circuit board 18 is supported on the lugs 15 and the supports 16, the end faces of which lie in a plane "a", and the light-emitting diodes 19 protrude into the through openings 14, which together with the lugs 15 form light channels. As a result, a sufficient seal against contamination of the light-emitting diodes is achieved, even if there is a lot of play between the wall 9 of the housing 1 and the printed circuit board 18 for assembly. The sealing effect can be further improved in that a material with a certain elastomeric effect is used for the housing and, if necessary, suitable sealing lips are formed on the light channels.
Die FIGUR 5 zeigt ein Anordnungsbeispiel der erfindungsgemäßen Anzeigeeinrichtung beispielsweise auf einem Armaturenbrett 26. Denkbar ist selbstverständlich auch ein frontflächenbündiger, versenkter Einbau der Anzeigeeinrichtung. FIGURE 5 shows an arrangement example of the display device according to the invention, for example on a dashboard 26. Of course, a flush installation of the display device flush with the front surface is also conceivable.
