Description

Die Erfindung betrifft eine Eingabeeinheit für ein druck- und drehbetätigbares Bedienelement, mit einem walzenförmigen Eingabeelement, das auf einem Träger drehbar gelagert ist, wobei der Träger gegen ein Gehäuseteil verschwenkbar angeordnet ist.The invention relates to an input unit for a pressure- and drehbetätigbares operating element, with a cylindrical input member which is rotatably mounted on a support, wherein the carrier is pivotally mounted against a housing part.

Viele Bedienelemente, insbesondere solche in Kraftfahrzeugen, werden heutzutage mit mehreren Funktionen belegt. Als Beispiel sei ein Lenkradbedienelement mit einem Drehrändel genannt, das unbegrenzt drehbar ist und das zusätzlich eine oder mehrere druckbetätigbare Schaltfunktionen aufweist. Um Fehlbedienungen zu vermeiden, ist es erwünscht, dass verschiedene Betätigungsarten nicht gleichzeitig ausgeführt werden können.Many controls, especially those in motor vehicles, are nowadays assigned several functions. As an example, a steering wheel control element with a rotary handle is called, which is infinitely rotatable and which additionally has one or more pressure-actuated switching functions. In order to avoid erroneous operations, it is desirable that various types of actuation can not be performed simultaneously.

Ein derartiges druck- und drehbetätigbares Bedienelement ist beispielsweise aus der deutschen Patentanmeldung DE 10 2011 103 670 A1 bekannt. Bei dem in diesem Dokument beschriebenen Bedienelement ist ein annähernd zylinderförmiges Eingabeelement mit einer Welle verbunden, die auf einem Träger gelagert ist. Ebenfalls mit der Welle verbunden ist ein Drehsensor, ausgeführt beispielsweise durch eine Codescheibe und eine Gabellichtschranke, welcher Drehbetätigungen des Eingabeelements erfasst. Der Träger ist auf mindestens einen Schaltelement gelagert, das bei einer Druckeinwirkung auf das Eingabeelement ein elektrisches Signal erzeugt. Die Schaltelemente können als Mikroschalter oder als Schaltdome einer Domschaltmatte ausgeführt sein.Such a pressure and drehbetätigbares control element is for example from the German patent application DE 10 2011 103 670 A1 known. In the operating element described in this document, an approximately cylindrical input element is connected to a shaft which is mounted on a carrier. Also connected to the shaft is a rotation sensor, embodied for example by a code disk and a fork light barrier, which detects rotational actuations of the input element. The carrier is mounted on at least one switching element which generates an electrical signal when pressure is applied to the input element. The switching elements can be designed as microswitches or as switching domes of a Domschaltmatte.

Ein außerhalb des Eingabeelements auf der Welle angeordnetes Rastrad weist entlang seines Umfangs eine angeformte Rastkurve auf. An dieser Rastkurve liegt ein Rastbolzen an, der an einem drehbaren, federbelasteten Hebel angeordnet ist. Hierdurch erfolgt eine Drehbetätigung des Eingabeelements gegen die Kraft der Feder in mehreren aufeinanderfolgenden Raststufen. Bei einer Druckbetätigung des Eingabeelements fährt der Hebel gegen einen Anschlag und verhindert durch eine Blockierung des Rastrads die gleichzeitige Ausführung einer Drehbetätigung. Umgekehrt lenken bei einer Drehbetätigung die Erhebungen der Rastkurve am Rastrad den Hebel aus, wodurch eine gleichzeitige Druckbetätigung unterbunden wird.A ratchet wheel arranged outside the input element on the shaft has an integrally formed latching cam along its circumference. At this latching curve is a locking bolt, which on a rotatable, spring-loaded Lever is arranged. As a result, a rotary actuation of the input element takes place against the force of the spring in several successive latching steps. In a pressure actuation of the input element of the lever moves against a stop and prevented by blocking the ratchet wheel, the simultaneous execution of a rotary actuator. Conversely, in a rotary actuation, the elevations of the latching cam on the ratchet wheel deflect the lever, whereby a simultaneous pressure actuation is prevented.

Nachteilig an dieser vorbekannten Eingabeeinheit ist, dass das Rastrad und der zugeordnete Rasthebel einen vergleichsweise großen Bauraum benötigen.A disadvantage of this known input unit that the ratchet wheel and the associated locking lever require a relatively large space.

Es stellte sich die Aufgabe, eine besonders einfach und kompakt ausgebildete Eingabeeinheit mit Sperrfunktionen zu schaffen, die während der Ausführung einer Druck- oder Drehbetätigung die gleichzeitige Ausführung der jeweils anderen Betätigungsart verhindern.It has set itself the task of creating a particularly simple and compact input unit with locking functions that prevent the simultaneous execution of the other type of actuation during the execution of a printing or rotary actuator.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Eingabeelement einen Hohlraum aufweist, in der ein Rastkurvenkörper verschiebbar angeordnet ist, dass eine Stirnseite des Rastkurvenkörpers eine Rastkurve aufweist, die durch eine in axialer Richtung des Eingabeelements auf den Rastkurvenkörper wirkende Feder gegen eine Rastnase am Träger gedrückt wird, und dass die andere Stirnseite des Rastkurvenkörpers eine oder mehrere Anformungen aufweist, die durch eine axiale Verschiebung des Rastkurvenkörpers gegen das Eingabeelement in eine Ausnehmung des Gehäuseteils einschiebbar sind.This object is achieved in that the input element has a cavity in which a latching cam is slidably disposed, that an end face of the latching cam has a latching cam, which is pressed by a force acting in the axial direction of the input element on the latching cam spring against a latch on the carrier is, and that the other end face of the latching cam body has one or more projections, which can be inserted by an axial displacement of the locking cam against the input member in a recess of the housing part.

Die mit der Stirnseite des Rastkurvenkörpers verbundene oder daran angeformte Rastkurve sowie auch die bewegliche Anordnung des Rastkurvenkörpers in einem Hohlraum des Eingabeelements ermöglichen einen sehr kompakten Aufbau der Eingabeeinheit, insbesondere da kein Einbauraum für ein Rastrad neben dem Eingabeelement vorgesehen werden muss.The latching curve connected to or integrally formed with the end face of the latching cam body as well as the movable arrangement of the latching cam body in a cavity of the input element allow a very compact design of the input unit, in particular no Installation space for a ratchet next to the input element must be provided.

Im Folgenden soll der Aufbau und die Funktionsweise einer erfindungsgemäßen Eingabeeinheit anhand eines in der Zeichnung skizzierten Ausführungsbeispiels näher erläutert werden. Die Figuren 1, 3 und 5 zeigen jeweils eine Schnittansicht durch eine Eingabeeinheit, und zwar in verschiedenen Betätigungszuständen. Die neben den Schnittansichten angeordneten Figuren 2, 4 und 6 zeigen jeweils eine zum jeweiligen Betätigungszustand gehörende Ansicht einer Stirnseite der Eingabeeinheit.In the following, the structure and operation of an input unit according to the invention will be explained in more detail with reference to an embodiment sketched in the drawing. The FIGS. 1, 3 and 5 each show a sectional view through an input unit, in different operating states. The arranged next to the sectional views FIGS. 2, 4 and 6 each show a belonging to the respective operating state view of an end face of the input unit.

Die Figur 1 zeigt eine Schnittansicht durch eine Eingabeeinheit als Bestandteil eines druck- und drehbetätigbaren Bedienelements, wie es beispielsweise am Lenkrad eines Kraftfahrzeugs zur Anwendung kommen kann. Von dem Bedienelement ist somit lediglich die Eingabeeinheit dargestellt, die ein auf einem Träger 2 angeordnetes und gegen ein Gehäuseteil 3 verschwenkbar angeordnetes Eingabeelement 1 aufweist.The FIG. 1 shows a sectional view through an input unit as part of a pressure and rotatably operable control element, such as may be used for example on the steering wheel of a motor vehicle. Of the control element thus only the input unit is shown, which has a arranged on a support 2 and against a housing part 3 pivotally arranged input element 1.

Nicht dargestellt sind hier elektronische und elektromechanische Komponenten des Bedienelements, wie beispielsweise Drehsensoren, Schalter oder Domschaltmatten, deren Beschreibung zur Darstellung der Erfindung nebensächlich ist und deren mögliche Ausgestaltungen, beispielsweise aus der Beschreibung der deutschen Offenlegungsschrift DE 10 2011 670 A1 , bekannt sind.Not shown here are electronic and electromechanical components of the control element, such as rotary sensors, switches or Domschaltmatten whose description is incidental to the presentation of the invention and their possible embodiments, for example, from the description of the German Offenlegungsschrift DE 10 2011 670 A1 , are known.

Die Eingabeeinheit weist ein rotationssymmetrisches walzenförmiges Eingabeelement 1 auf, welches mittels einer entlang seiner Symmetrieachse verlaufenden Welle 9 drehbar an einem Träger 2 gelagert ist. Mit der Welle 9 verbunden und vorzugsweise am Träger 2 befestigt ist ein hier nicht dargestellter elektrischer Drehsensor, der beispielsweise durch eine Gabellichtschranke oder einen elektrischen Impulsgeber ausgeführt sein kann, die bzw. der auf grundsätzlich bekannte und daher hier nicht näher beschriebene Weise, Drehbetätigungen des mit der Welle 9 verbundenen Eingabeelements 1 erfasst und in auswertbare elektrische Signale umsetzt. Am Anbauort des Bedienelements ist ein Teilabschnitt der Mantelfläche 13 des Eingabeelements 1 über eine Ausnehmung in einer Bedienblende 12 zugänglich, so dass das Eingabeelement 1 zusammen mit der Welle 9 gedreht werden kann.The input unit has a rotationally symmetrical roller-shaped input element 1, which is rotatably mounted on a carrier 2 by means of a shaft 9 running along its axis of symmetry. Connected to the shaft 9 and preferably attached to the carrier 2 is an electric rotary sensor, not shown here, which may be implemented, for example, by a forked light barrier or an electric pulse generator. the or the basically known and therefore not described in detail here, rotational actuations of the connected to the shaft 9 input element 1 detects and converts into evaluable electrical signals. At the place of attachment of the control element, a section of the lateral surface 13 of the input element 1 is accessible via a recess in a control panel 12, so that the input element 1 can be rotated together with the shaft 9.

Neben der Drehbetätigung sind eine oder mehrere Arten von Druckbetätigungen des Bedienelements vorgesehen, welche durch Krafteinwirkungen senkrecht auf den zugänglichen Mantelflächenabschnitt 13 des Eingabeelements 1 erfolgen. Die Druckbetätigungen bewirken ein Verschwenken des Trägers 2 gegen das Gehäuseteil 3, so dass fest zum Gehäuseteil 3 angeordnete Schaltelemente, beispielsweise hier nicht dargestellte Dome einer Domschaltmatte, ausgelenkt werden, wodurch elektrische Schaltkontakte geschlossen oder geöffnet werden.In addition to the rotary actuation one or more types of pressure actuation of the operating element are provided, which take place by force effects perpendicular to the accessible lateral surface portion 13 of the input element 1. The pressure actuations effect a pivoting of the carrier 2 against the housing part 3, so that fixed to the housing part 3 arranged switching elements, for example, not shown domes of a Domschaltmatte be deflected, whereby electrical switching contacts are closed or opened.

Wie die Figur 1 zeigt, bildet das Innere des Eingabeelements 1 einen Hohlraum 14 aus, in dem ein Rastkurvenkörper 10 verschiebbar angeordnet ist. Der Rastkurvenkörper 10 weist an einer Stirnseite eine angeformte Rastkurve 4 und an der entgegengesetzten Stirnseite mehrere Anformungen 7 auf. Wie die Figur 2 verdeutlicht sind die, hier beispielhaft vier, Anformungen 7 stiftförmig ausgestaltet und symmetrisch und parallel zur Welle 9 ausgerichtet.As the FIG. 1 shows, the interior of the input element 1 forms a cavity 14, in which a latching cam 10 is slidably disposed. The latching cam 10 has an integrally formed latching cam 4 on one end side and a plurality of projections 7 on the opposite end side. As the FIG. 2 Illustrated are the exemplary four, projections 7 pin-shaped and aligned symmetrically and parallel to the shaft 9.

Die mit dem Rastkurvenkörper 10 verbundene oder daran angeformte Rastkurve 4 bildet eine Vielzahl regelmäßiger Erhöhungen und Vertiefungen aus, an denen eine am Träger 2 angeordnete Rastnase 5 anliegt. Die Rastkurve 4 wird von einer Druckfeder 6 belastet, die sich am Eingabeelement 1 abstützt und die Rastkurve 4 gegen die Rastnase 5 presst. In der Figur 1 ist die Lage des Rastkurvenkörpers 10 dargestellt, die dieser relativ zum Eingabeelement 1 einnimmt, wenn dieses weder druck- noch drehbetätigt ist (Neutralstellung).The detent curve 4 connected to or formed on the latching cam 10 forms a plurality of regular elevations and depressions against which a latching nose 5 arranged on the carrier 2 rests. The latching cam 4 is loaded by a compression spring 6, which is supported on the input element 1 and the latching cam 4 presses against the latching lug 5. In the FIG. 1 the position of the locking cam 10 is shown, this relative to Input element 1 assumes, if this is neither pressure nor rotationally operated (neutral position).

Bei einer Drehbetätigung des Eingabeelements 1, symbolisch angedeutet durch den in der Figur 4 dargestellten gebogenen Doppelpfeil, dreht das Eingabeelement 1 den Rastkurvenkörper 10 mit sich, so dass die Rastkurve 4 an der am Träger 2 angeordneten Rastnase 5 am entlang geführt wird. Da dabei die Rastnase 5 stets an den Erhebungen und Vertiefungen der Rastkurve 4 anliegt, bewegt sich der Rastkurvenkörper 10 in axialer Richtung entlang der Welle 9 vor und zurück (Figur 3).In a rotary operation of the input element 1, symbolically indicated by the in the FIG. 4 shown curved double arrow, the input element 1 rotates the locking cam body 10 with it, so that the latching cam 4 is guided on the arranged on the carrier 2 locking lug 5 along. Since the locking lug 5 always bears against the elevations and depressions of the latching cam 4, the latching cam body 10 moves back and forth in the axial direction along the shaft 9 (FIG. FIG. 3 ).

Bereits in der Neutralstellung (Figur 1), bei der die Rastnase 5 in eine der Vertiefungen der Rastkurve 4 eingreift, ist der Abstand zwischen den Enden der stiftförmigen Anformungen 7 und dem Wandabschnitt 11 des Gehäuseteils 3 relativ klein, und zwar insbesondere geringer als die Höhe der Erhebungen der Rastkurve 4. Liegt somit während einer Drehbetätigung (Figur 4) eine der Erhebungen der Rastkurve 4 an der Rastnase 5 an, so ist der Rastkurvenkörper 10 soweit gegen die Feder 6 verschoben, dass dessen Anformungen 7 in eine Ausnehmung 8 im Wandabschnitt 11 eingreifen (Figur 3). Da dies bei einer Drehbewegung des Eingabeelements 1 in schneller Abfolge periodisch erfolgt, blockieren die in die Ausnehmung 8 eingreifenden Anformungen 7 dadurch eine senkrechte Verschwenk- oder Verschiebebewegung des Trägers 2.Already in the neutral position ( FIG. 1 ), in which the latching lug 5 engages in one of the recesses of the latching cam 4, the distance between the ends of the pin-shaped projections 7 and the wall portion 11 of the housing part 3 is relatively small, in particular less than the height of the elevations of the latching curve 4. Lies thus during a rotary operation ( FIG. 4 ) one of the elevations of the latching cam 4 on the latching lug 5, the latching cam 10 is displaced so far against the spring 6 that its projections 7 engage in a recess 8 in the wall section 11 ( FIG. 3 ). Since this occurs periodically in a rotational movement of the input element 1 in rapid succession, the projections 7 engaging in the recess 8 thereby block a vertical pivoting or sliding movement of the carrier 2.

Ohne eine Drehbetätigung greift die Rastnase 5 in eine Vertiefung der Rastkurve 4 ein, wodurch die Anformungen 7, wie in den Figuren 1 und 5 dargestellt, noch vor dem Wandabschnitt 11 enden und ein Verschieben oder Verschwenken des Trägers 2 durch eine Druckbetätigung nicht blockieren.Without a rotary operation engages the locking lug 5 in a recess of the latching cam 4, whereby the projections 7, as in the FIGS. 1 and 5 illustrated, even before the wall portion 11 end and do not block a displacement or pivoting of the carrier 2 by a pressure actuation.

Erfolgt eine Druckbetätigung durch eine Krafteinwirkung auf das Eingabeelement 1, so bewegt sich der Träger 2 mit dem Eingabeelement 1 in Richtung auf das Gehäuseteil 3. Wie die Figuren 5 und 6 zeigen, befinden sich dann zumindest einige der Anformungen 7 unterhalb der Ausnehmung 8 des Wandabschnitts 11. Da der Abstand zwischen den Anformungen 7 und dem massiven Teil des Wandabschnitts 11 geringer ist als die Höhe der Erhebungen der Rastkurve 4, gelingt es jetzt nicht mehr, durch eine Drehung des Eingabeelements 1 de Erhebungen der Rastkurve 4 an der Rastnase 5 vorbeizubewegen, da die Anformungen 7 bereits vorher auf den Wandabschnitt 11 treffen und die Verschiebung des Rastkurvenkörpers 10 gegen das Eingabeelement 1 aufhalten. Dadurch wird bei einer Druckbetätigung des Eingabeelements 1 eine gleichzeitige Drehbewegung blockiert.If a pressure actuation by a force on the input element 1, then the carrier 2 moves with the input element 1 in Direction to the housing part 3. Like the FIGS. 5 and 6 show, then at least some of the projections 7 are below the recess 8 of the wall portion 11. Since the distance between the projections 7 and the solid part of the wall portion 11 is less than the height of the elevations of the latching cam 4, it is no longer possible by a rotation of the input element 1 de elevations of the latching cam 4 move past the locking lug 5, since the projections 7 already meet previously on the wall portion 11 and stop the displacement of the detent cam 10 against the input element 1. As a result, a simultaneous rotational movement is blocked in a pressure actuation of the input element 1.

Derartige Bedienelemente können vorzugsweise in Kraftfahrzeugen zur Anwendung kommen und insbesondere als Koppelelemente in Lenkradbedienschaltern, Mittelkonsolen und Armaturenbretter eingesetzt werden.Such controls can preferably be used in motor vehicles and in particular be used as coupling elements in steering wheel control switches, center consoles and dashboards.
