Abstract

The invention is based on a control module for motor vehicle switches which comprises a plurality of illuminated windows for displaying the functional state of the module and for finding the module when the vehicle interior is in darkness. The object of the invention is to provide this module with as few components as possible and configure it such that it can be easily assembled. The object is achieved in that a light guide for illuminating at least one window is provided and can simultaneously be used for accommodating at least one incandescent lamp. Advantageous developments are concerned with keeping streams of light emerging from an incandescent lamp held in the light guide remote from the light guide itself and from an illuminated window in dependence on the function of a push-button.

Description

Elektrisches Steuermodul mit Lichtleiter zur Aufnahme min¬ destens einer GlühlampeElectrical control module with light guide for receiving at least one incandescent lamp
Die Erfindung betrifft ein elektrisches Steuermodul, bei dem über ein oder mehrere Fenster in der Frontplatte die¬ ses Moduls der augenblickliche Zustand dieses Moduls ange¬ zeigt wird. Bei diesem Zustand kann es sich beispielsweise um einen Schaltzustand oder auch um die Anzeige der Lage eines Betätigungsgliedes handeln. Der Zustand kann aber auch einen Funktionszustand eines dem Modul nachgeschalte¬ ten Aggregats betreffen.The invention relates to an electrical control module in which the current state of this module is indicated via one or more windows in the front panel of this module. This state can be, for example, a switching state or the display of the position of an actuator. However, the state can also relate to a functional state of an assembly downstream of the module.
Derartige Module, bei denen es sich vorzugsweise, aber nicht unbedingt um Schalter handelt, sind aus dem Stand der Technik bekannt.Such modules, which are preferably, but not necessarily, switches are known from the prior art.
So zeigt beispielsweise die US-PS 35 18 386 einen von ei¬ ner Glühlampe angestrahlten Lichtleiter, der aus einer Summe von einzelnen Lichtleitungen besteht, welche zu ge¬ trennten Schaltern führen.For example, US Pat. No. 3,518,386 shows a light guide which is illuminated by an incandescent lamp and which consists of a sum of individual light guides which lead to separate switches.
Aus der US-PS 41 63 883 ist es bekannt, eine Reihe von Be- tätigungseinricntungen eines Schalters aus jeweils einem Lichtleiter aufzubauen, dem jeweils eine Glühlampe fest zugeordnet ist. Die Beleuchtung erfolgt unabhängig von dem Zustand des jeweiligen Schalters. Aus der US-PS 43 54 080 ist es bekannt, über eine Lampe einen drehbeweglichen Lichtleiter auszuleuchten, dessen Stellung über entsprechende Fenster in dem Schaltergehäuse erkennbar ist.From US Pat. No. 4,163,883 it is known to construct a series of actuating devices of a switch from one light guide each, to which a light bulb is permanently assigned. The lighting is independent of the state of the respective switch. From US-PS 43 54 080 it is known to illuminate a rotatable light guide via a lamp, the position of which can be recognized via corresponding windows in the switch housing.
Entsprechendes gilt für die DE-OS 27 23 692, wobei hier die Fenster ohne Verwendung eines Lichtleiters direkt durch die Glühlampe ausgeleuchtet werden.The same applies to DE-OS 27 23 692, where the windows are illuminated directly by the incandescent lamp without using an optical fiber.
Aus der DE-AS 22 03 232 ist die Taste eines Kippschalters mit zwei Lichtleitern versehen, die in Abhängigkeit von der Stellung der Taste das Licht einer Glühlampe entweder zu dem einen oder zu dem anderen Leiter und damit zu des¬ sen Austrittsfenster führen.From DE-AS 22 03 232 the button of a toggle switch is provided with two light guides which, depending on the position of the button, lead the light of an incandescent lamp either to one or the other wire and thus to its exit window.
Die Erfindung geht daher aus von einem elektrischen Steuermodul der sich aus dem Oberbegriff des Anspruchs 1 ergebenden Gattung.The invention is therefore based on an electrical control module of the type resulting from the preamble of claim 1.
Aufgabe der Erfindung ist es, den Raumbedarf dieses Moduls durch eine besonders zweckmäßige Ausgestaltung des Licht¬ leiters zu verringern. Zusätzlich soll dieses Modul nicht nur unterschiedliche Schaltzustände darstellen können, sondern darüber hinaus besonders einfach zusammenbaubar sein.The object of the invention is to reduce the space requirement of this module by a particularly expedient design of the light guide. In addition, this module should not only be able to represent different switching states, but should also be particularly easy to assemble.
Die Aufgabe wird durch die sich aus dem kennzeichnenden Teil des Anspruchs 1 ergebender Merkmalskombination ge¬ löst. Die Erfindung besteht im Prinzip also darin, den Lichtleiter mit mindestens einer Glühlampe zu bestücken und mit dem Lichtleiter die verschiedenen Fenster ggf. in Abhängigkeit des Modulzustandes auszuleuchten. Durch die mechanische Aufnahme der Glühlampe in dem Lichtleiter ist deren wichtige Zuordnung eindeutig festgelegt. Gleichzei¬ tig erübrigt sich eine getrennte Montage von Glühlampe und Lichtleiter innerhalb des Moduls.The object is achieved by the combination of features resulting from the characterizing part of claim 1. In principle, the invention therefore consists in equipping the light guide with at least one incandescent lamp and, if necessary, in the various windows with the light guide Depending on the module status. The mechanical assignment of the incandescent lamp in the light guide clearly defines its important assignment. At the same time, there is no need to separately mount the incandescent lamp and light guide within the module.
Eine besonders zweckmäßige Ausgestaltung des erfindungsge¬ mäßen Moduls ergibt sich durch die Merkmalskombination nach Anspruch 2. Danach wird eines der Fenster durch die Glühlampe direkt angeleuchtet, während ein Teil des von der Glühlampe abgegebenen Lichts zu dem zweiten Fenster transportiert wird. Somit ist es möglich, daß der Licht¬ leiter die Glühlampe nur von einer Seite her abdeckt und somit die Belüftung der Glühlampe nur geringfügig behin¬ dert. Dabei kann beispielsweise das Brennen der Glühlampe den Aktivierungszustand des Moduls selbst anzeigen und die über den Lichtleiter transportierte Strahlung in dem zwei¬ ten Feld eine besondere Form des Aktivierungstands als möglichen Zustande des Moduls anzeigen. So ist es bei¬ spielsweise denkbar, daß das erste Fenster anzeigt, daß die Beleuchtung eines Kraftfahrzeugs eingeschaltet ist, während das zweite Fenster angibt, ob eine Taste niederge¬ drückt ist und damit Fernlicht oder Abblendlicht einge¬ schaltet ist. Eine andere Anwendungsmöglichkeit für das erfindungsgemäße Modul kann darin bestehen, mit dem Ein-, schalten der KFZ-Beleuchtung auch die Suche nach dem Modul innerhalb des ansonsten unbeleuchteten Tableaus zu er¬ leichtern und mit Hilfe des zweiten Fensters den einge¬ schalteten Funktionszustand des Moduls (Tempostat, Tractioncontrol oder automatische Kupplung eingeschaltet bzw. ausgeschaltet) anzuzeigen. Bei derartigen Forderungen eignet sich besonders eine Aus¬ gestaltung gemäß der Merkmalskombination nach Anspruch 3.A particularly expedient embodiment of the module according to the invention results from the combination of features according to claim 2. Thereafter, one of the windows is illuminated directly by the incandescent lamp, while part of the light emitted by the incandescent lamp is transported to the second window. It is thus possible for the light guide to cover the incandescent lamp only from one side and thus to hinder the ventilation of the incandescent lamp only slightly. In this case, for example, the burning of the incandescent lamp itself can indicate the activation state of the module and the radiation transported via the light guide in the second field can show a special form of the activation state as possible states of the module. For example, it is conceivable that the first window indicates that the lighting of a motor vehicle is switched on, while the second window indicates whether a key is depressed and thus high beam or low beam is switched on. Another possible application for the module according to the invention can be to simplify the search for the module within the otherwise unlit panel by switching the vehicle lighting on and to use the second window to switch on the functional state of the module ( Speed post, traction control or automatic clutch switched on or off). In the case of such demands, a configuration according to the combination of features according to claim 3 is particularly suitable.
In Weiterbildung der Erfindung empfiehlt es sich, zusätz¬ lich zu der o.g. ersten Glühlampe zumindest noch eine wei¬ tere Glühlampe in den Lichtleiter aufzunehmen. Dabei kön¬ nen die funktionsabhängig beleuchteten Felder (z.B. zwei¬ tes Feld und drittes Feld) derart gestaltet sein, daß das zweite Feld die Bedienbarkeit eines Schalters angibt und das dritte Feld die durch die Bedienung des Schalters aus¬ gelöste Funktion zeigt.In a development of the invention, it is advisable to add to the above. first incandescent lamp to include at least one further incandescent lamp in the light guide. The functionally illuminated fields (e.g. second field and third field) can be designed such that the second field indicates the operability of a switch and the third field shows the function triggered by the operation of the switch.
Will man nun mehrere Glühlampen innerhalb des Lichtleiters anordnen, so muß darauf geachtet werden, daß der von den Glühlampen abgegebene Lichtstrom sich innerhalb des Licht¬ leiters nicht überlagert und so zu falschen Meldungsergeb¬ nissen führt. Hierzu empfiehlt sich in Weiterbildung die Merkmalskombination nach Anspruch 5. Da in dem zentral von der Glühlampe getroffenen Teil des Lichtleiters ein beson¬ ders großer Lichtstrom übertragen wird, gleichzeitig eine mechanische Verbindung zwischen dem Licht übertragenden Lichtleiter und der abzuschirmenden Fassung einer Glühlam¬ pe in dem Lichtleiter erreicht werden soll, wird in vor¬ teilhafter Weiterbildung die Merkmalskombination nach An¬ spruch 6 vorgeschlagen.If you now want to arrange several incandescent lamps within the light guide, care must be taken that the luminous flux emitted by the incandescent lamps does not overlap within the light guide and thus leads to incorrect reporting results. For this purpose, the combination of features according to claim 5 is recommended in a further development. Since a particularly large luminous flux is transmitted in the part of the light guide that is hit centrally by the incandescent lamp, a mechanical connection between the light-transmitting light guide and the version of a light bulb to be shielded is simultaneously provided in the If light guides are to be achieved, the combination of features according to claim 6 is proposed in an advantageous further development.
Nachdem mehrere Glühlampen auf einem Lichtleiter sitzen und somit eine Baueinheit bilden, läßt sich vorteilhaft die Merkmalskombination nach Anspruch 7 anwenden. Bei ei¬ ner vermehrten Anzahl von zu dem Modul gehörenden Bauele¬ menten, zu denen beispielsweise Schalter und Anschluß- stücke für Kontakte gehören können, wird zur Aufnahme der Bauelemente eine zusätzliche Bestückungsebene entsprechend den Maßnahmen nach Anspruch 8 empfohlen.After several light bulbs sit on a light guide and thus form a structural unit, the combination of features according to claim 7 can advantageously be used. With an increased number of components belonging to the module, to which, for example, switches and connection pieces for contacts, an additional assembly level according to the measures according to claim 8 is recommended to accommodate the components.
Das erfindungsgemäße Modul läßt sich auch vielfach anwen¬ den, beispielsweise bei einem Tableau für Kraftfahrzeuge. Hierzu empfiehlt sich in Weiterbildung die Merkmalskombi¬ nation nach Anspruch 9, bei der die mit dem Bodenteil ver¬ sehenen Module in zugeordneter Aufnahme einer Bedienungs- leiste des Kraftfahrzeugs einrastbar sind.The module according to the invention can also be used in many ways, for example in a panel for motor vehicles. For this purpose, in a further development the combination of features according to claim 9 is recommended, in which the modules provided with the base part can be snapped into the associated receptacle of an operating bar of the motor vehicle.
Das erfindungsgemäße Modul ist aufgrund der in den Licht¬ leiter integrierten Glühlampen vergleichsweise einfach zu¬ sammensetzbar. Besonders günstig ist dabei die Verwendung der Merkmalskombination nach Anspruch 10.The module according to the invention is comparatively simple to assemble due to the incandescent lamps integrated in the light guide. The use of the combination of features according to claim 10 is particularly favorable.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend an¬ hand der Zeichnung erläutert.An embodiment of the invention is explained below with reference to the drawing.
In eine Aufnahmeplatte 1 eines Kraftfahrzeugs ist durch eine geeignete lösbare Verbindung eine Aufnahme 2 eingera¬ stet, die zur Aufnahme eines erfindungsgemäßen Moduls 3 dient. Das Modul selbst besteht aus einem Bodenteil 4, welches mittels zweier gegenüberliegender Rastfedern 5 in die Aufnahme 2 eingerastet ist. In das Bodenteil selbst,, welches beispielsweise den ortsfesten Kontakt 6 nebst An¬ schlußfahne 7 oder einem Druckschalter oder andere Bauele¬ mente trägt, ist eine Verbindungsleitungen aufweisende Platine 8 eingerastet, wobei durch von der Grundplatte hochragende Stützen und/oder Anschlußstücke 10 die Platine gegenüber der Grundplatte im Abstand gehalten wird. Auf die Platine ist ein Lichtleiter 11 aufgebracht und an dieser befestigt, beispielsweise durch Aufklemmen oder Aufrasten. Dabei können beispielsweise in der Figur nicht dargestellte Rastnasen des Lichtleiters in entsprechende Ausnehmungen der Platine eingreifen. Eine andere Möglich¬ keit zur Fixierung des Lichtleiters auf der Platine be¬ steht in der Anwendung von Klemmbolzen 21, die in zugeord¬ nete Öffnungen der Platine 8 ragen. Der Lichtleiter 11 ist mit zwei Glühlampen 12,13 bestückt, so daß der LichtleiterA receptacle 2 is used in a receptacle plate 1 of a motor vehicle by means of a suitable detachable connection, which receptacle is used to hold a module 3 according to the invention. The module itself consists of a base part 4, which is snapped into the receptacle 2 by means of two opposite catch springs 5. In the bottom part itself, which carries, for example, the fixed contact 6 together with the connecting lug 7 or a pressure switch or other components, a circuit board 8 having connecting lines is latched, with supports and / or connecting pieces 10 projecting from the base plate opposite the circuit board the base plate is kept at a distance. A light guide 11 is applied to the circuit board and fastened to it, for example by clamping or snapping on. In this case, latching noses of the light guide, not shown in the figure, can engage in corresponding recesses in the circuit board. Another possibility for fixing the light guide on the circuit board is to use clamping bolts 21 which protrude into assigned openings in the circuit board 8. The light guide 11 is equipped with two light bulbs 12, 13 so that the light guide
11 die Fassung für diese beiden Glühlampen bildet.11 forms the socket for these two light bulbs.
Mit dem Bodenteil 4 ist nach dem Einrasten der bestückten Platine eine Frontplatte 14 rastend verbunden, so daß die Frontplatte von dem Bodenteil, z.B. zum Auswechseln der Glühlampen oder der gesamten Platine 8, abgenommen werden kann. In die Frontplatte 14 ist ein erstes Fenster 15 aus durchsichtigem Material angegossen, wobei das erste Fen¬ ster 15 derart angeordnet ist, das fest durch die direkte Strahlung der Glühlampe 12 ausgeleuchtet wird. In der Frontplatte 14 ist weiterhin noch eine Drucktaste 18 ent¬ gegen der Kraft zweier Rückholfedern 25 verschiebbar ge¬ führt, so daß diese Taste in die Frontplatte 14 eindrück¬ bar ist.With the bottom part 4, a front plate 14 is connected in a latching manner after the populated circuit board has snapped in, so that the front plate is removed from the bottom part, e.g. to replace the light bulbs or the entire board 8, can be removed. A first window 15 made of transparent material is cast in the front plate 14, the first window 15 being arranged in such a way that it is firmly illuminated by the direct radiation of the incandescent lamp 12. In the front plate 14 there is also a push button 18 which can be moved against the force of two return springs 25 so that this button can be pressed into the front plate 14.
Die Drucktaste 18 besitzt ein zweites Fenster 16 und ein drittes Fenster 17, wobei das zweite Fenster 16 durch die über den Lichtleiter 14 geführte Strahlung der GlühlampeThe pushbutton 18 has a second window 16 and a third window 17, the second window 16 due to the radiation of the incandescent lamp which is guided through the light guide 14
12 ausgeleuchtet wird. Das dritte Fenster 17 wird durch die zweite Glühlampe 13 beleuchtet, welche ebenfalls von dem Lichtleiter 11 getragen wird. Die Glühlampe 13 dient an sich zur Anzeige einer Schaltfunktion in dem dritten Fenster 17. Für den Fall, daß die Drucktaste 18 als rastende Taste ausgestaltet ist, ist aber auch die Konstellation denkbar, daß auf die Glühlampe 13 verzichtet und die vom Lichtlei¬ ter kommende Strahlung gemessen wird, welche über eine als Blende wirkende, mit dem Druckschalter 18 bewegliche Wand 19 (in Abhängigkeit von der Stellung der Drucktaste 18 zu einem Ansatz 20) durchgelassen wird oder nicht.12 is illuminated. The third window 17 is illuminated by the second light bulb 13, which is also carried by the light guide 11. Incandescent lamp 13 is used in itself to display a switching function in third window 17. In the event that the push button 18 is designed as a latching button, the constellation is also conceivable that the incandescent lamp 13 is dispensed with and the radiation coming from the light guide is measured, which radiation acts via a diaphragm and is movable with the push switch 18 Wall 19 (depending on the position of the push button 18 to an extension 20) is let through or not.
Eine andere Möglichkeit besteht darin, über eine mit der Drucktaste 18 verbundene verlängerte Wand, wie beispiels¬ weise die Wand 19, die von der zweiten Glühlampe.13 zum Lichtleiter 11 abgegebene Strahlung in Abhängigkeit von der Lage der Drucktaste 18 zu dosieren, so daß bei abge¬ schalteter Glühlampe 12 die Beleuchtung des zweiten Fen¬ sters 16 in Abhängigkeit von der Lage des Druckschalters 18 erfolgt. Ein Vorteil der Erfindung liegt u.a. auch darin, daß der aus Kunststoff bestehende Lichtleiter gleichzeitig zur Isolation der Zuleitungsdrähte für die Glühlampen 12 und 13 dient. Weiterhin kann durch eine Löt¬ verbindung zwischen einer Verbindungsleitung auf der Pla¬ tine 8 und den Zuleitungen 23 der Glühlampe der Lichtlei¬ ter 11 zusätzlich gegenüber der Platine 8 gesichert wer¬ den. Die Rastnase 24 des Lichtleiters dient zu dessen Auf- rastung auf der Platine 8. Seitliche Stützwände 30 der Fenster 15 und 16 dienen zu einer erhöhten Lichtaufnahme dieser Fenster, da der durch die Wände zusätzlich einge¬ fangene Lichtstrom durch die Fenster 15,16 abgegeben wer¬ den kann. Weiterhin ist es möglich, daß die Drucktaste 18 mit einem sich an der Platine vorbei bis in die Nähe einer Grundplatte 26 des Bodenteils 4 erstreckenden Vorsprung versehen ist, durch welchen versehen ist, durch welchen ein auf der Grundplatte 26 montierter Schalter direkt durch die Drucktaste 18 ausgelöst werden kann. Another possibility is to use an extended wall connected to the pushbutton 18, such as the wall 19, for the second incandescent lamp . 13 to emit radiation emitted to the light guide 11 as a function of the position of the pushbutton 18, so that when the incandescent lamp 12 is switched off the second window 16 is illuminated as a function of the position of the pressure switch 18. An advantage of the invention is, inter alia, that the light guide made of plastic serves at the same time for the insulation of the lead wires for the light bulbs 12 and 13. Furthermore, the light guide 11 can additionally be secured relative to the board 8 by a soldered connection between a connecting line on the board 8 and the leads 23 of the incandescent lamp. The latching lug 24 of the light guide serves to snap it onto the circuit board 8. Lateral support walls 30 of the windows 15 and 16 serve to increase the light absorption of these windows, since the luminous flux additionally captured by the walls is emitted through the windows 15, 16 ¬ can. Furthermore, it is possible that the pushbutton 18 is provided with a projection which extends past the circuit board and into the vicinity of a base plate 26 of the base part 4, by which projection a switch mounted on the base plate 26 can be triggered directly by the pushbutton 18.
