Description

Die Erfindung bezieht sich auf einen Multifunktionsschalter, insbesondere für ein Kraftfahrzeug, mit einem getastet kreuzweise verschwenkbar sowie verdrehbar gelagerten Betätigungselement, dem vier kreuzförmig zueinander angeordnete und mit einer Auswerteeinheit sowie Anschlusskontakten gekoppelte Druckschalter für elektrische Schaltfunktionen zugeordnet sind.The invention relates to a multi-function switch, in particular for a motor vehicle, with a keyed crosswise pivotable and rotatably mounted actuator, the four cross-shaped arranged one another and associated with an evaluation unit and connection contacts pressure switch for electrical switching functions are assigned.

Die DE 103 39 469 A1 offenbart einen Multifunktionsschalter, der durch Drehen, Druckbeaufschlagung sowie Verschwenken eines Betätigungselementes zu betätigen ist, und bei dem die durch die Drehbetätigung sowie durch die Druckbetätigung erzeugten Signale von einem elektronischen Bauteil ausgegeben werden, während die durch das Verschwenken des dem elektronischen Bauteil zugeordneten Betätigungselementes erzeugten elektrischen Signale von vier Druckschaltern ausgegeben werden, die durch Kippen des Betätigungselementes um zwei senkrecht zueinander angeordnete Achsen betätigt werden. Um mehrere, beispielsweise acht, durch Verschwenken des Betätigungselementes ansteuerbare Schaltfunktionen zu realisieren, sind acht Druckschalter erforderlich, deren Verwendung mit erheblichem Kostenaufwand verbunden ist.The DE 103 39 469 A1 discloses a multi-function switch to be operated by turning, pressurizing and pivoting of an actuating element, and in which the signals generated by the rotary actuator and by the pressure operation are output from an electronic component, while the generated by the pivoting of the electronic component associated with the actuating element Signals are issued by four pressure switches, which are actuated by tilting the actuating element about two mutually perpendicular axes. In order to realize several, for example, eight, by pivoting the actuating element controllable switching functions, eight pressure switches are required, the use of which is associated with considerable cost.

Es ist Aufgabe der Erfindung, einen Multifunktionsschalter der eingangs genannten Art zu schaffen, der kostengünstig herstellbar ist. Insbesondere sollen mit vier Druckschaltern acht Schaltfunktionen realisiert werden können.It is an object of the invention to provide a multi-function switch of the type mentioned, which is inexpensive to produce. In particular, eight switching functions should be able to be realized with four pressure switches.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass den vier Druckschaltern acht Schaltfunktionen in sternförmigen Schwenkschaltstellungen des Betätigungselementes zugeordnet sind.According to the invention the object is achieved in that the four pressure switches eight switching functions are assigned in star-shaped pivoting positions of the actuating element.

Durch die Kopplung der Druckschalter mit der Auswerteeinheit sind den Schaltstellungen eindeutige Schaltsignale zuzuordnen, wobei beispielsweise einigen Schaltstellungen lediglich ein einziger Druckschalter und in weiteren Schaltstellungen mehrere Druckschalter beaufschlagt werden. Durch diese Ausgestaltung des Multifunktionsschalters ist gegenüber dem Stand der Technik eine reduzierte Anzahl von Druckschaltern vorgesehen, wodurch ein kostengünstiger Aufbau realisiert ist.By coupling the pressure switch with the evaluation unit the switching positions unique switching signals are assigned, for example, some switching positions only a single pressure switch and in other switching positions more pressure switch are acted upon. By this embodiment of the multi-function switch a reduced number of pressure switches is provided over the prior art, whereby a cost-effective design is realized.

Zur Konkretisierung des Erfindungsgedankens ist das Betätigungselement um vier Schwenkachsen verschwenkbar gelagert, die paarweise senkrecht zueinander stehen, wobei die Schwenkachsen des ersten Paares gegenüber den Schwenkachsen des zweiten Paares um einen bestimmten Winkelbetrag versetzt angeordnet sind.To concretize the inventive concept, the actuating element is pivotally mounted about four pivot axes, which are perpendicular to each other in pairs, wherein the pivot axes of the first pair are arranged offset from the pivot axes of the second pair by a certain angular amount.

Nach einer vorteilhaften Weiterbildung des Erfindungsgegenstandes wird durch Verschwenken des Betätigungselementes um jeweils eine Schwenkachse des ersten Paares jeweils ein Druckschalter betätigt, während durch Verschwenken des Betätigungselementes um jeweils eine Schwenkachse des zweiten Paares zwei benachbart angeordnete Druckschalter betätigt werden. In Verbindung mit der Auswerteeinheit ist eine eindeutige Zuordnung der beaufschlagten Druckschalter zu der jeweiligen Schaltstellung und damit der Schaltfunktion gewährleistet.According to an advantageous embodiment of the subject invention, in each case a pressure switch is actuated by pivoting the actuating element about a respective pivot axis of the first pair, while by pivoting the Actuating element are actuated by a respective pivot axis of the second pair of two adjacent pressure switch.

Der Mehrfunktionsschalter gemäß Fig. 1 und 2 besteht im Wesentlichen aus einem Betätigungselement bzw. einem als Druck- und Drehknopf ausgebildeten Betätigungselement 1, einem Gehäuse 2, in dem das Betätigungselement 1 geführt ist, einer Schaltmatte 3, einer unterhalb der Schaltmatte 3 angeordneten Leiterplatte 4 sowie einem Sockel 5. Weiterhin ist das Betätigungselement 1 in einer Kardanaufhängung 6 in acht Richtungen verschwenkbar gelagert. Die Kardanaufhängung 6 wird ihrerseits durch ein erstes Gelenkteil 7 sowie ein vorzugsweise ringförmiges zweites Gelenkteil 8 gebildet, das im Gehäuse 2 gelagert ist. Im ersten Gelenkteil 7 sind federnd vorgespannte Rasthülsen 9, 10 (s. Fig. 2) angeordnet, die gerastete oder getastete Schaltstellungen des Betätigungselementes 1 definieren. Die Rasthülsen 9, 10 gleiten dabei auf einer haptischen Kurve 11, so dass dem Benutzer ein angenehmes taktiles Gefühl vermittelt wird. Im mittleren Bereich des Betätigungselementes 1 ist eine Druckfeder 12 angeordnet, die sich einerseits am Betätigungselement 1 und andererseits an einem Führungsstift 14 abstützt, der seinerseits in einer Vertiefung 13 des Sockels 5 abgestützt ist. Innerhalb der Vertiefung 13 ist eine nicht dargestellte Rastkurve ausgebildet. Um ein unbeabsichtigtes Verschwenken des Betätigungselementes 1 zu verhindern, drückt der Führungsstift 14 das Betätigungselement 1 in seine neutrale Schaltstellung zurück.The multi-function switch according to Fig. 1 and 2 consists essentially of an actuator or designed as a push-button and knob actuator 1, a housing 2 in which the actuator 1 is guided, a switching mat 3, arranged below the switching mat 3 circuit board 4 and a base 5. Furthermore, that is Actuator 1 mounted in a gimbal 6 in eight directions pivotable. The gimbal 6 is in turn formed by a first hinge part 7 and a preferably annular second hinge part 8, which is mounted in the housing 2. In the first joint part 7 resiliently biased latching sleeves 9, 10 (s. Fig. 2 ), which define the latched or keyed switching positions of the actuating element 1. The snap-on sleeves 9, 10 slide on a haptic curve 11, so that the user is given a pleasant tactile feeling. In the central region of the actuating element 1, a compression spring 12 is arranged, which is supported on the one hand on the actuating element 1 and on the other hand on a guide pin 14, which in turn is supported in a recess 13 of the base 5. Within the recess 13 is a Not shown locking curve formed. In order to prevent unintentional pivoting of the actuating element 1, the guide pin 14 presses the actuating element 1 back into its neutral switching position.

Um durch eine Drehbetätigung des Betätigungselementes 1 elektrische Signale erzeugen zu können, ist im Gehäuse 2 ein Drehgeber vorgesehen, der, mit einem nicht dargestellten Lichtsensor zusammen wirkend, der berührungslosen Erfassung der Drehbewegung des Betätigungselementes 1 dient und der als eine Lichtbarriere bzw. eine Gabellichtschranke 15 ausgebildet ist, die durch eine auf der Schaltmatte 3 angeordnete, nicht dargestellte Lichtquelle bzw. eine LED-Diode hinterleuchtet wird. Obwohl die erwähnte berührungslose Erfassung der Drehbewegung des Betätigungselementes 1 im gezeigten Ausführungsbeispiel auf optischem Prinzip erfolgt, kann sie selbstverständlich auch z. B. nach magnetischem Prinzip durchgeführt werden. Außerdem ist zwischen dem ersten Gelenkteil 7 und der Gabellichtschranke 15 ein kugelsegmentförmiges Kraftübertragungsteil 16 vorgesehen, während zwischen der Gabellichtschranke 15 und eines im Bereich der Vertiefung 13 ausgebildeten Führungsabschnitts 17 des Sockels 5 ein Gleitstück 18 angeordnet ist, das die Führung des Betätigungselementes 1 im Sockel 5 unterstützt.In order to generate electrical signals by a rotary actuation of the actuating element 1, a rotary encoder is provided in the housing 2, which cooperates with a light sensor, not shown, the non-contact detection of the rotational movement of the actuating element 1 and serves as a light barrier or a forked light barrier 15 is formed, which is backlit by an arranged on the switching mat 3, not shown light source or an LED diode. Although the mentioned non-contact detection of the rotational movement of the actuating element 1 in the embodiment shown takes place on optical principle, it can of course also z. B. be carried out according to magnetic principle. In addition, a spherical segment-shaped power transmission member 16 is provided between the first joint part 7 and the fork light barrier 15, while between the fork light barrier 15 and formed in the recess 13 guide portion 17 of the base 5, a slider 18 is arranged, which guides the actuator 1 in the base. 5 supported.

Um durch eine Beaufschlagung des Betätigungselementes 1 durch Druckbeaufschlagung oder Verschwenken elektrische Signale erzeugen zu können, weist die Schaltmatte 3 vier Druckschalter 21, 22, 23, 24 (s. insbesondere Fig. 3) auf, die kreuzförmig zueinander angeordnet und mit einer Auswerteeinheit gekoppelt sind. Die Auswerteeinheit kann entweder schalterseitig auf der Leiterplatte 4 oder außerhalb des Schalters, beispielsweise in einem Kraftfahrzeug, angeordnet sein. Die Druckschalter 21, 22, 23, 24 werden durch im Gehäuse 2 geführte, federnd vorgespannte Aktuatoren 25 - 28 (Fig. 3) betätigt.In order to be able to generate electrical signals by pressurizing or actuating the actuating element 1, the switching mat 3 has four pressure switches 21, 22, 23, 24 (see in particular FIG Fig. 3 ), which are arranged crosswise to each other and coupled to an evaluation unit. The evaluation unit can either switch side on the circuit board 4 or outside of the switch, for example in a motor vehicle, be arranged. The pressure switches 21, 22, 23, 24 are guided in the housing 2, spring-biased actuators 25 - 28 ( Fig. 3 ).

Bei der Druckbetätigung des Schalters wird das Betätigungselement 1 in Richtung seiner Drehachse bewegt. Während der Druckfunktion drückt das Betätigungselement 1 das kugelsegmentförmige Kraftübertragungsteil 16 auf die Gabellichtschranke 15, deren axiale Bewegung auf das Gleitstück 18 übertragen wird. Das Gleitstück 18 drückt die Schaltmatte 3 nach unten, wodurch die vorstehend erwähnten Druckschalter 21, 22, 23 und 24 im Sinne einer Signalerzeugung betätigt werden. Damit die Schaltmatte 3 senkrecht nach unten gedrückt wird, wird das Gleitstück 18 in dem vorstehend erwähnten Führungsabschnitt 17 des Sockels 5 geführt. Wenn sich das Betätigungselement 1 während der Druckbetätigung außerhalb seiner zentralen Lage befindet, wird die Druckkraft in der axialen Richtung in das kugelsegmentförmige Kraftübertragungsteil 16 sowie die Gabellichtschranke 15 eingeleitet.When the pushbutton of the switch, the actuating element 1 is moved in the direction of its axis of rotation. During the printing function, the actuating element 1 presses the ball-segment-shaped power transmission part 16 on the fork light barrier 15, whose axial movement is transmitted to the slider 18. The slider 18 pushes the switching mat 3 down, whereby the aforementioned pressure switches 21, 22, 23 and 24 are actuated in the sense of a signal generation. Thus, the switching mat 3 is pressed vertically downwards, the slider 18 is guided in the above-mentioned guide portion 17 of the base 5. When the operating member 1 is out of its central position during the printing operation, the pressing force in the axial direction is introduced into the ball segment-shaped power transmission member 16 and the fork light barrier 15.

Bei der Betätigung des Multifunktionsschalters durch Verschwenken des Betätigungselementes 1 ermöglicht die Kardanaufhängung 6 ein spielfreies Verschwenken des Betätigungselementes 1 um vier Schwenkachsen, die paarweise senkrecht zueinender stehen. Dabei sind die Schwenkachsen des zweiten Paares gegenüber den Schwenkachsen des ersten Paares um einen bestimmten Betrag, im gezeigten Beispiel um 45°, versetzt angeordnet. Bei der Betätigung wird das Betätigungselement 1 in einer Richtung bzw. um eine der Schwenkachsen verschwenkt, wodurch das drehbar gelagerte erste Gelenkteil 7 einen oder zwei unter ihm im Gehäuse 2 geführte Aktuatoren 25 - 28 nach unten drückt. Durch diese Bewegung wird die Schaltmatte 3 wieder nach unten gedrückt, wodurch die entsprechenden Druckschalter 21 - 24 betätigt werden. Die Zuordnung der einzelnen Schwenkschaltstellungen ist dabei vorzugsweise derart getroffen, dass beim Verschwenken des Betätigungselementes 1 um die Achsen des ersten Paares jeweils ein Druckschalter 21 - 24 betätigt wird, während beim Verschwenken des Betätigungselementes 1 um die Achsen des zweiten Paares jeweils zwei benachbarte Druckschalter 21, 22 bzw. 23, 24 betätigt werden. Mit definierten, nicht dargestellten Endanschlägen kann der Betätigungsweg der Druckschalter 21 - 24 begrenzt und ein Niederdrücken des Betätigungselementes 1 während des Verschwenkens verhindert werden.Upon actuation of the multi-function switch by pivoting the actuating element 1, the cardan suspension 6 allows a backlash-free pivoting of the actuating element 1 by four pivot axes, which are pairwise perpendicular zueinender. In this case, the pivot axes of the second pair with respect to the pivot axes of the first pair by a certain amount, in the example shown by 45 °, arranged offset. Upon actuation, the actuator becomes 1 pivoted in one direction or about one of the pivot axes, whereby the rotatably mounted first hinge part 7 presses one or two actuated below him in the housing 2 actuators 25 - 28 down. By this movement, the switching mat 3 is pressed down again, whereby the corresponding pressure switch 21 - 24 are actuated. The assignment of the individual pivoting switch positions is preferably made such that when pivoting of the actuating element 1 about the axes of the first pair each a pressure switch 21 - 24 is actuated, while the pivoting of the actuating element 1 about the axes of the second pair each two adjacent pressure switch 21, 22 and 23, 24 are operated. With defined end stops, not shown, the actuation of the pressure switch 21 - 24 limited and a depression of the actuating element 1 can be prevented during pivoting.

Bei der in den Fig. 4 und 5 gezeigten, konstruktiv vereinfacht ausgeführten zweiten Ausführung des Multifunktionsschalters wird das Betätigungselement 1 durch einen Schwenk- und Druckknopf 30 sowie einen hohlen, den Schwenk- und Druckknopf 30 radial umgreifenden Drehknopf 31 gebildet, die getrennt voneinander angeordnet sind. Die Bewegungen des tellerförmigen Schwenk- und Druckknopfes 30 werden mittels eines sich durch eine Führung 38 hindurch erstreckenden stabförmigen Teiles 32 auf ein an dessen Ende ausgebildetes Kugelgelenk 33 übertragen, das der Lagerung des Schwenk- und Druckknopfes 30 am Sockel 5 dient. Das Kugelgelenk 33 trägt vier an seinem Umfang in gleichen Winkelabständen von 90° ausgebildete Betätigungsarme 34, 35, 36, 37 zur Betätigung der Druckschalter 21 - 24.In the in the 4 and 5 shown, structurally simplified executed second embodiment of the multi-function switch, the actuator 1 by a swivel and push button 30 and a hollow, the pivot and push button 30 radially encompassing knob 31 are formed, which are arranged separately. The movements of the plate-shaped pivot and push button 30 are transmitted by means of a guide 38 extending therethrough rod-shaped part 32 on a ball joint 33 formed at the end, which serves to support the pivot and push button 30 on the base 5. The ball joint 33 carries four at its circumference at equal angular intervals formed by 90 ° actuating arms 34, 35, 36, 37 for actuating the pressure switch 21 - 24.

Die im Zusammenhang mit der ersten Ausführung erwähnten federnd belasteten Rasthülsen 9, 10 sind bei der zweiten Ausführung in entsprechenden Ausnehmungen des Drehknopfes 31 senkrecht angeordnet. Eine der berührungslosen Erfassung der Drehbewegung des Drehknopfes 31 dienende Lichtbarriere 39 ist im unteren Bereich des Drehknopfes 31 mit ihm einteilig ausgebildet. Eine die Lichtbarriere 39 hinterleuchtende Lichtquelle sowie ein Lichtsensor sind nicht dargestellt.The resiliently loaded latching sleeves 9, 10 mentioned in connection with the first embodiment are arranged vertically in corresponding recesses of the rotary knob 31 in the second embodiment. One of the non-contact detection of the rotational movement of the knob 31 serving light barrier 39 is integrally formed with him in the lower region of the knob 31. A light barrier 39 backlit light source and a light sensor are not shown.

Die Betätigung der in den Fig. 4 und 5 gezeigten zweiten Ausführung des Multifunktionsschalters durch Drehen des Drehknopfes 31 sowie durch Verschwenken des Schwenk- und Druckknopfes 30 entsprechen weitgehend den Betätigungsvorgängen der ersten Ausführung und werden daher nicht näher erläutert.The operation of the in the 4 and 5 shown second embodiment of the multi-function switch by turning the knob 31 and by pivoting the pan and push button 30 largely correspond to the actuation processes of the first embodiment and are therefore not explained in detail.

Die in Fig. 6 dargestellte erste Auswerteschaltung dient einer analogen Verarbeitung der von den Druckschaltern 21 - 24 erzeugten elektrischen Signale, die Steuereingängen von vier bipolaren bzw. pnp-Transistoren 40, 41, 42, 43 zugeführt werden, deren Kollektoren einerseits mit den Steuereingängen von vier npn-Transistoren 44 - 47 einer ersten Signalverarbeitungsschaltung 50 und andererseits paarweise den Eingängen von vier AND-Gatter 51 - 54 zugeführt werden, deren Ausgangssignale den Steuereingängen weiterer vier npn-Transistoren 55 - 58 zugeführt werden, die zusammen mit den AND-Gattern 51 - 54 eine zweite Signalverarbeitungsschaltung 60 bilden. Dabei werden die Signale der einzelnen Druckschalter 21 - 24 von der ersten Signalverarbeitungsschaltung 50 und die Signale der benachbart angeordneten zwei Druckschaltern 21, 22; 23, 24 von der zweiten Signalverarbeitungsschaltung 60 verarbeitet, wobei die Ausgangssignale der beiden Signalverarbeitungsschaltungen 50, 60 mittels zweier A/D-Konverter eines externen Mikroprozessors ausgewertet werden. Wenn z. B. der Druckschalter 21 betätigt wird, wird der Transistor 40 umgeschaltet und stellt ein "1"-Signal für die Basis des Transistors 44 zur Verfügung. Dadurch wird der Transistor 44 geschaltet und stellt eine entsprechende Spannung am Ausgang der widerstandskodierten Schaltung bereit. Wenn dagegen die Druckschalter 21 und 22 betätigt werden, werden die Transistoren 40 und 41 geschaltet und stellen "1"-Signale an beiden Eingängen des ersten AND-Gatters 51 bereit, dessen Ausgangssignal einen hohen Spannungspegel annimmt. Dadurch wird der Transistor 55 geschaltet und stellt eine entsprechende Spannung am Ausgang der widerstandskodierten Schaltung bereit.In the Fig. 6 The first evaluation circuit shown serves for analog processing of the electrical signals generated by the pressure switches 21-24, to which the control inputs of four bipolar or pnp transistors 40, 41, 42, 43 are supplied, whose collectors on the one hand are connected to the control inputs of four npn transistors 44 - 47 of a first signal processing circuit 50 and on the other hand in pairs the inputs of four AND gates 51 - 54 are supplied, the output signals to the control inputs of another four npn transistors 55 - 58 are supplied, which together with the AND gates 51 - 54, a second signal processing circuit 60 form. In this case, the signals of the individual pressure switches 21-24 from the first signal processing circuit 50 and the signals of the adjacently arranged two pressure switches 21, 22; 23, 24 processed by the second signal processing circuit 60, wherein the output signals of the two signal processing circuits 50, 60 are evaluated by means of two A / D converter of an external microprocessor. If z. B. the pressure switch 21 is actuated, the transistor 40 is switched and provides a "1" signal for the base of the transistor 44 available. As a result, the transistor 44 is switched and provides a corresponding voltage at the output of the resistance-coded circuit. On the other hand, when the pressure switches 21 and 22 are operated, the transistors 40 and 41 are switched to provide "1" signals at both inputs of the first AND gate 51 whose output signal becomes a high voltage level. As a result, the transistor 55 is switched and provides a corresponding voltage at the output of the resistance-coded circuit.

Die in Fig. 7 dargestellte zweite Auswerteschaltung dient schließlich einer digitalen Verarbeitung der von den Druckschaltern 21 - 24 erzeugten elektrischen Signale, die Steuereingängen von vier bipolaren bzw. pnp-Transistoren 70, 71, 72, 73 zugeführt werden, deren Ausgangssignale direkt in die digitalen Eingängen eines Mikroprozessors eingelesen werden, der deren Auswertung vornimmt.In the Fig. 7 Finally, the second evaluation circuit shown serves for digital processing of the electrical signals generated by the pressure switches 21-24, which are supplied to control inputs of four bipolar or pnp transistors 70, 71, 72, 73 whose output signals are read directly into the digital inputs of a microprocessor who carries out their evaluation.
