Description

Die Erfindung betrifft einen elektrischen Schalter, insbesondere einen Wipp- oder Kippschalter.The invention relates to an electrical switch, in particular a rocker or toggle switch.

Wippschalter, die in Kraftfahrzeugen, insbesondere in Lenkrädern, zum Einsatz kommen, unterliegen meist strengen Bauraumbeschränkungen. Eine flache Bauweise von Wippschaltern ist unter Verwendung von Mikroschaltelementen oder Schnappscheiben möglich, die unmittelbar durch eine Wippbewegung eines Betätigungsteils betätigt werden können. Diese Bauteile sind jedoch verhältnismäßig teuer, sodass solche Wippschalter nicht kostengünstig herstellbar sind.Rocker switches, which are used in motor vehicles, especially in steering wheels, are usually subject to strict installation space limitations. A flat construction of rocker switches is possible using micro-switching elements or snap-action discs which can be actuated directly by a rocking movement of an actuating part. However, these components are relatively expensive, so that such rocker switch can not be produced inexpensively.

Es sind auch andere Wippschalterkonzepte bekannt, die den Einsatz von kostengünstigeren Schaltmatten erlauben. So ist in der DE 102 06 777 A1 ein gattungsgemäßer Schalter mit einer schwenkbar gelagerten Schalterwippe gezeigt. Ausgehend von ihrer Neutralstellung ist die Schalterwippe bezüglich der Neutralstellung in gegenüberliegende Funktionsstellungen schwenkbar, in denen durch die Schalterwippe jeweils ein oder mehrere elektrische Schalterelemente betätigt werden. Die bei diesem Konzept vorgesehene "schräge" Betätigung der Schalterelemente geht jedoch mit einem nicht unwesentlichen Haptikverlust einher.There are also other Wippschalterkonzepte known, which allow the use of lower-cost safety mats. So is in the DE 102 06 777 A1 a generic switch with a pivotally mounted rocker switch shown. Starting from its neutral position, the rocker switch is pivotable relative to the neutral position in opposite functional positions, in which one or more electrical switch elements are actuated by the rocker switch. The "oblique" operation of the switch elements provided in this concept, however, is accompanied by a not insignificant haptic loss.

Aus der EP 2 053 623 A2 ist ein gattungsgemäßer elektrischer Schalter bekannt, der eine Betätigungskappe aufweist, die schwenkbar gelagert und manuell bedienbar ist, wobei die Betätigungskappe eine Steuerkontur aufweist, über die auf einem Übertagungsglied beweglich gelagert ist.From the EP 2 053 623 A2 a generic electrical switch is known which has an actuating cap which is pivotally mounted and manually operated, wherein the actuating cap has a control contour, is movably mounted on a Übertagungsglied.

Weitere elektrische Schalter sind aus der DE 10 2007 052 655 A1 sowie der DE 34 33 603 A1 bekannt.Other electrical switches are from the DE 10 2007 052 655 A1 as well as the DE 34 33 603 A1 known.

Aufgabe der Erfindung ist es, einen für den Kraftfahrzeugbereich geeigneten, kostengünstigen und zuverlässigen elektrischen Schalter mit angenehmer Haptik beim Schaltvorgang zu schaffen, der mit einer kleinen Bauhöhe realisierbar ist.The object of the invention is to provide a suitable for the automotive sector, inexpensive and reliable electrical switch with a pleasant feel during the switching process, which is feasible with a small height.

Gelöst wird diese Aufgabe durch einen elektrischen Schalter mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen des erfindungsgemäßen elektrischen Schalters sind in den Unteransprüchen angegeben.This object is achieved by an electrical switch with the features of claim 1. Advantageous embodiments of the electrical switch according to the invention are specified in the dependent claims.

Der erfindungsgemäße elektrische Schalter, insbesondere ein Wipp- oder Kippschalter, umfasst ein dreh- oder schwenkbar gelagertes, manuell bedienbares Betätigungsteil, das aus einer Neutralstellung in eine Betätigungsstellung auslenkbar ist. Der elektrische Schalter umfasst ferner ein elektrisches Schaltelement, das mechanisch betätigbar ist, und ein auf das Schaltelement einwirkendes Betätigungselement. Das Betätigungselement ist so an das Betätigungsteil und an das Schaltelement gekoppelt, dass eine Dreh- oder Schwenkbewegung des Betätigungsteils aus der Neutralstellung in die Betätigungsstellung in eine im Wesentlichen lineare Bewegung des Betätigungselements umgesetzt wird. Das Betätigungselement ist ferner drehbar an das Betätigungsteil gekoppelt, indem wenigstens ein Achsabschnitt des Betätigungselements in einer schlüssellochförmigen Aufnahme des Betätigungsteils drehbar gelagert ist.The electrical switch according to the invention, in particular a rocker or toggle switch, comprises a rotatably or pivotally mounted, manually operable actuating part which can be deflected from a neutral position into an actuating position. The electrical switch further comprises an electrical switching element, which is mechanically actuated, and an actuating element acting on the switching element. The actuating element is coupled to the actuating part and to the switching element such that a rotary or pivoting movement of the actuating part from the neutral position to the actuating position is converted into a substantially linear movement of the actuating element. The actuating element is further rotatably coupled to the actuating part by at least one axis portion of the actuating element is rotatably mounted in a keyhole-shaped receptacle of the actuating part.

Dadurch erhält das Betätigungselement gegenüber dem Betätigungsteil einen zusätzlichen Freiheitsgrad, sodass ein ansonsten durch die Dreh- bzw. Schwenkbewegung des Betätigungsteils verursachtes Kippen des Betätigungselements aus der bevorzugten linearen Schaltrichtung des Schaltelements ausgeglichen werden kann. Des Weiteren ist auf diese Weise die drehbare Kopplung des Betätigungselements an das Betätigungsteil einfach umgesetzt.As a result, the actuating element is given an additional degree of freedom with respect to the actuating part, so that tilting of the actuating element otherwise caused by the rotational or pivoting movement of the actuating part can be compensated for from the preferred linear switching direction of the switching element. Furthermore, the rotatable coupling of the actuating element to the actuating part is simply implemented in this way.

Der erfindungsgemäße Aufbau erlaubt den Einsatz einer Schaltmatte als elektrisches Schaltelement, sodass der Schalter insgesamt sehr flach ausgelegt werden kann. Die besondere Kopplung des Betätigungsteils, die die Dreh- oder Schwenkbewegung des Betätigungsteils in eine lineare Bewegung des Betätigungselements umwandelt, ermöglicht eine senkrechte Einwirkung des Betätigungselements auf die Schaltmatte. Dadurch ist eine zuverlässige und haptisch angenehme Betätigung der Schaltmatte gewährleistet.The structure of the invention allows the use of a switching mat as an electrical switching element, so that the switch can be designed very flat overall. The special coupling of the actuating part, which converts the rotary or pivoting movement of the actuating part into a linear movement of the actuating element, allows a vertical action of the actuating element on the switching mat. This ensures a reliable and tactile pleasant operation of the switching mat.

Ein unerwünschtes Ausweichen des Betätigungselements beim Betätigen des Schalters kann dadurch vermieden werden, dass die drehbare Kopplung des Betätigungselements an das Betätigungsteil so ausgelegt ist, dass dem Betätigungselement keine lineare Bewegung in einer zur Drehachse des Betätigungselements senkrechten Richtung gestattet ist.An undesirable deflection of the actuating element during actuation of the switch can be avoided in that the rotatable coupling of the actuating element to the actuating part is designed so that the actuating element is not allowed to move linearly in a direction perpendicular to the axis of rotation of the actuating element.

Damit das (begrenzt) bewegliche Betätigungselement während des Schaltvorgangs eine definierte Orientierung relativ zum Schaltelement beibehält, weist das Betätigungselement vorzugsweise einen Kontaktabschnitt auf, der zumindest in der Betätigungsstellung auf einer Erhöhung des Schaltelements aufliegt.So that the (limited) movable actuating element during the switching operation maintains a defined orientation relative to the switching element, this has Actuator preferably has a contact portion which rests at least in the operating position on an increase of the switching element.

Vorteilhaft kann gemäß einer Fortführung des obigen Aspekts eine stabile Neutralstellung des Schalters vorgegeben werden, indem der Kontaktabschnitt (auch) in der Neutralstellung unter Vorspannung auf der Erhöhung des Schaltelements aufliegt (selbstverständlich ohne dass dadurch ein Schaltvorgang ausgelöst wird).Advantageously, according to a continuation of the above aspect, a stable neutral position of the switch can be specified by the contact section (also) in the neutral position under bias on the increase of the switching element rests (of course, without this a switching operation is triggered).

Gemäß einer Weiterbildung des Betätigungselements weist dessen Kontaktabschnitt einen Rand auf, der die Erhöhung des Schaltelements umgreift, vorzugsweise mit einem Spiel. Der dadurch mehr oder weniger erreichte Formschluss zwischen dem Betätigungselement und dem Schaltelement sichert die gewünschte Positionierung des Betätigungselements relativ zum Schaltelement zusätzlich ab. Ein gewisses Spiel zwischen dem Rand des Betätigungselements und der Erhöhung des Schaltelements lässt während des Schaltvorgangs eine prinzipbedingte minimale translatorische Verschiebung des Betätigungselements relativ zum Schaltelement ohne einen haptisch störenden Widerstand zu.According to a development of the actuating element, its contact portion has an edge which surrounds the elevation of the switching element, preferably with a clearance. The thus achieved more or less positive engagement between the actuating element and the switching element secures the desired positioning of the actuating element relative to the switching element in addition. A certain play between the edge of the actuating element and the increase in the switching element during the switching operation allows for a principle-dependent minimum translational displacement of the actuating element relative to the switching element without a haptic disturbing resistance.

Das erfindungsgemäße Schalterkonzept kann ausgedehnt werden auf einen Wippschalter mit zwei Betätigungsstellungen, die durch Schwenken oder Drehen eines zweiarmigen Betätigungselements in entgegengesetzte Dreh- bzw. Schwenkrichtungen erreicht werden (rocker switch). Hierzu sind auf gegenüberliegenden Seiten einer Dreh- oder Schwenkachse, um die das Betätigungsteil auslenkbar ist, zwei Betätigungselemente an das Betätigungsteil und jeweils an ein auf einer Seite der Achse angeordnetes elektrisches Schaltelement so gekoppelt, dass Dreh- oder Schwenkbewegungen des Betätigungsteils aus der Neutralstellung in entgegengesetzte Richtungen jeweils in eine im Wesentlichen lineare Bewegung des Betätigungselements umgesetzt werden.The inventive switch concept can be extended to a rocker switch with two operating positions, which are achieved by pivoting or turning a two-armed actuator in opposite directions of rotation or rocking (rocker switch). For this purpose, on opposite sides of a rotary or pivot axis about which the actuating member is deflectable, two actuators coupled to the actuating part and each arranged on one side of the axis electrical switching element so that rotational or pivotal movements of the actuating member from the neutral position in opposite Directions are translated into a substantially linear movement of the actuating element.

In den Figuren 1 und 2 ist eine erste Ausführungsform eines elektrischen Wippschalters mit einer manuell bedienbaren Drucktaste 10 gezeigt. Die Drucktaste 10 ist Teil eines Betätigungsteils 12 des Schalters, das aus einer Neutralstellung ( Figur 1 ) in eine Betätigungsstellung ( Figur 2 ) auslenkbar ist. Hierzu ist das Betätigungsteil 12 an einem relativ zur Bewegung des Betätigungsteils 12 feststehenden Bauteil dreh- oder schwenkbar um eine Dreh- bzw. Schwenkachse 14 gelagert.In the Figures 1 and 2 a first embodiment of an electric rocker switch with a manually operated pushbutton 10 is shown. The push button 10 is part of an actuating part 12 of the switch, which consists of a neutral position ( FIG. 1 ) in an actuating position ( FIG. 2 ) is deflectable. For this purpose, the actuating member 12 is rotatably mounted on a relative to the movement of the actuating member 12 fixed component or pivotable about a pivot axis 14.

Ebenfalls auf einem relativ zur Bewegung des Betätigungsteils 12 feststehenden Bauteil ist ein elektrisches Schaltelement 16 in Form einer Schaltmatte (Gummischaltmatte) angebracht. Das Schaltelement 16 hat eine Erhöhung 18. Durch Niederdrücken der Erhöhung 18 in einer Schaltrichtung 20 wird ein elektrischer Schaltvorgang ausgelöst. Charakteristisch für eine Schaltmatte ist dabei die taktile Rückmeldung, die als Schnappen empfunden wird.Also on a relative to the movement of the actuating member 12 fixed component, an electrical switching element 16 in the form of a switching mat (Gummischaltmatte) is mounted. The switching element 16 has an increase 18. By depressing the increase 18 in a switching direction 20, an electrical switching operation is triggered. Characteristic of a safety mat is the tactile feedback, which is perceived as a snap.

Der Schalter umfasst ferner ein auf das Schaltelement 16 einwirkendes Betätigungselement 22, das mechanisch einerseits an das Betätigungsteil 12 und andererseits an das Schaltelement 16, genauer gesagt an dessen Erhöhung 18 gekoppelt ist. Die Besonderheit dieser Kopplung liegt darin, dass eine Dreh- oder Schwenkbewegung des Betätigungsteils 12 aus der Neutralstellung in die Betätigungsstellung in eine im Wesentlichen lineare Bewegung des Betätigungselements 22 umgesetzt wird, wie nachfolgend im Detail erläutert wird.The switch further comprises an actuating element 22 which acts on the switching element 16 and which is mechanically coupled on the one hand to the actuating part 12 and on the other hand to the switching element 16, more precisely at its elevation 18. The peculiarity of this coupling is that a rotary or pivoting movement of the actuating part 12 is converted from the neutral position to the actuating position in a substantially linear movement of the actuating element 22, as will be explained in detail below.

Das in Figur 3 einzeln gezeigte Betätigungselement 22 weist einen mittleren Kontaktabschnitt 24 auf, von dem sich in entgegengesetzten Richtungen zwei Achsabschnitte 26 erstrecken. Wie am besten in Figur 4 zu erkennen ist, liegt das Betätigungselement 22 mit seinem Kontaktabschnitt 24 auf der Erhöhung 18 des Schaltelements 16 auf. Die Auflageflächen des Kontaktabschnitts 24 und der Erhöhung 18 sind ebenso wie die Achsabschnitte 26 senkrecht zur Schaltrichtung 20 orientiert.This in FIG. 3 individually shown actuator 22 has a central contact portion 24 from which extend in two axes portions 26 opposite directions. How best in FIG. 4 can be seen, the actuating element 22 is located with its contact portion 24 on the elevation 18 of the switching element 16. The bearing surfaces of the contact portion 24 and the elevation 18 are oriented as well as the axis portions 26 perpendicular to the switching direction 20.

In Figur 5 ist eine alternative Ausführungsvariante des Betätigungselements 22 gezeigt. Das Betätigungselement 22 weist einen sich von der Auflagefläche senkrecht erstreckenden Rand 28 auf, der die Erhöhung 18 des Schaltelements 16 in der Neutralstellung des Schalters umgreift. Zwischen dem Rand 18 und der Erhöhung 18 ist ein gewisses Spiel vorgesehen.In FIG. 5 an alternative embodiment of the actuating element 22 is shown. The actuator 22 has a vertically extending from the support surface edge 28 which engages around the elevation 18 of the switching element 16 in the neutral position of the switch. Between the edge 18 and the increase 18 a certain game is provided.

Die Achsabschnitte 26 des Betätigungselements 22 sind in Aufnahmen 30 des Betätigungsteils 12 drehbar gelagert. Die Aufnahmen 30 sind in Wandabschnitten 32 des Betätigungsteils 12, die sich senkrecht zu den Achsabschnitten 26 erstrecken, in Form eines Schlüssellochs gebildet. Die Schlüssellochform hat den Vorteil, dass die Achsabschnitte 26 einfach senkrecht zu ihrer Erstreckungsrichtung in die Aufnahmen 30 hineingedrückt werden können. Es sind jedoch auch andere Formen wie z. B. eine U-Form oder eine einfache Bohrung möglich. In jedem Fall ist dem Betätigungselement 22 keine lineare Bewegung in Richtung der Achsabschnitte 26 und vor allem keine lineare Bewegung in einer zur Richtung der Achsabschnitte 26 senkrechten Richtung gestattet. Somit ist das Betätigungselement 22 nur um eine zur Dreh- bzw. Schwenkachse 14 parallele Achse drehbar im Betätigungsteil 12 gelagert.The axle sections 26 of the actuating element 22 are rotatably mounted in receptacles 30 of the actuating part 12. The receptacles 30 are formed in wall sections 32 of the actuating part 12, which extend perpendicular to the Achsabschnitten 26, in the form of a keyhole. The keyhole shape has the advantage that the axle sections 26 can simply be pressed into the receptacles 30 perpendicular to their extension direction. However, there are other forms such. B. a U-shape or a simple bore possible. In any case, the actuator 22 is not allowed to move linearly in the direction of the axle sections 26 and above all does not permit linear movement in a direction perpendicular to the direction of the axle sections 26. Thus, the actuating element 22 is rotatably mounted in the actuating part 12 only about an axis parallel to the pivot axis or pivot axis 14.

Im Folgenden wird die Funktionsweise des Schalters erläutert. In der in Figur 1 gezeigten stabilen Neutralstellung liegt das Betätigungselement 22 unter definierter Vorspannung auf dem Schaltelement 16 auf. Die Vorspannung ist so bemessen, dass kein Schaltvorgang ausgelöst wird, d. h. die Erhöhung 18 des Schaltelements 16 wird wenig oder gar nicht niedergedrückt.The following explains the operation of the switch. In the in FIG. 1 shown stable neutral position, the actuator 22 is under defined bias on the switching element 16. The bias voltage is such that no switching operation is triggered, ie the increase 18 of the switching element 16 is little or not depressed.

Durch manuelle Betätigung der Drucktaste 10 wird das Betätigungsteil 12 ausgelenkt ( Figur 2 ), indem es eine Dreh- bzw. Schwenkbewegung um die Achse 14 vollführt. Das entfernt von der Achse 14 gelagerte Betätigungselement 22 wird dabei nicht gekippt, sondern behält seine Orientierung relativ zum Schaltelement 16 bei und drückt die Erhöhung 18 des Schaltelements 16 linear in Schaltrichtung 20, also senkrecht zu den Auflageflächen, nieder, sodass ein Schaltvorgang unter optimaler Krafteinleitung und taktiler Rückmeldung für den Bediener ausgelöst wird.By manual operation of the push button 10, the actuating member 12 is deflected ( FIG. 2 ) by making a pivotal movement about the axis 14. The mounted away from the axis 14 actuator 22 is not tilted, but retains its orientation relative to the switching element 16th at and pushes the increase 18 of the switching element 16 linearly in the switching direction 20, ie perpendicular to the support surfaces, down, so that a switching operation is triggered under optimum force and tactile feedback for the operator.

Das Betätigungselement 22 behält seine Orientierung bei, weil es im Betätigungsteil 12 drehbar um eine zur Dreh- bzw. Schwenkachse 14 des Betätigungsteils 12 parallele Achse gelagert ist und deshalb von der Erhöhung 18 des Schaltelements 16, insbesondere von deren Auflagefläche, in dieser Orientierung gehalten werden kann.The actuator 22 retains its orientation because it is rotatably mounted in the actuating part 12 about an axis parallel to the rotational or pivot axis 14 of the actuating member 12 and therefore held by the elevation 18 of the switching element 16, in particular of the support surface, in this orientation can.

In den Figuren 6 und 7 ist eine zweite Ausführungsform eines Wippschalters gezeigt. Dieser Schalter ist ausgehend von einer Neutralstellung ( Figur 6 ) in zwei Betätigungsstellungen auslenkbar. Die zweite Ausführungsform des Schalters beruht auf dem gleichen Prinzip wie die erste Ausführungsform und unterscheidet sich von dieser im Wesentlichen dadurch, dass nicht nur ein Betätigungselement 22 und ein mit diesem zusammenwirkendes Schaltelement 16 vorgesehen sind, sondern jeweils zwei. Die Schaltelemente 16 sind auf gegenüberliegenden Seiten der Dreh- bzw. Schwenkachse 14 angeordnet. Dementsprechend sind auch die Betätigungselemente 22 im Betätigungsteil 12 auf gegenüberliegenden Seiten der Dreh- bzw. Schwenkachse 14 drehbar gelagert.In the FIGS. 6 and 7 a second embodiment of a rocker switch is shown. This switch is based on a neutral position ( FIG. 6 ) in two operating positions deflected. The second embodiment of the switch is based on the same principle as the first embodiment and differs from this essentially in that not only an actuating element 22 and a cooperating with this switching element 16 are provided, but two each. The switching elements 16 are arranged on opposite sides of the pivot axis 14. Accordingly, the actuating elements 22 in the actuating part 12 are rotatably mounted on opposite sides of the rotary or pivot axis 14.

Der Aufbau des Schalters entspricht somit auf beiden Seiten dem oben beschriebenen, sodass insoweit auf die obigen Erläuterungen verwiesen werden kann, auch bezüglich der grundlegenden Funktionsweise. Je nach Dreh- bzw, Schwenkrichtung des Betätigungsteils 12 um die Dreh- bzw. Schwenkachse 14 wird hier das eine oder das andere Schaltelement 16 betätigt ( Figur 7 ). The construction of the switch thus corresponds on both sides to that described above, so that reference can be made in this respect to the above explanations, also with regard to the basic mode of operation. Depending on the rotational or pivoting direction of the actuating part 12 about the pivot axis 14, one or the other switching element 16 is actuated here ( FIG. FIG. 7 ).

Die beschriebenen Schalter eignen sich insbesondere als Wippschalter für Kfz-Lenkräder. Es sind jedoch auch andere Anwendungen denkbar, bei denen auf eine geringe Bauhöhe der Schalter und eine angenehme Haptik beim Schaltvorgang Wert gelegt wird.The switches described are particularly suitable as a rocker switch for vehicle steering wheels. However, other applications are conceivable in which emphasis is placed on a low height of the switch and a pleasant feel during the switching process.
