Abstract

The invention relates to an input unit for an operating element actuatable by pressure or rotation, comprising a cylindrical input element that is rotatably supported on a carrier. The carrier is arranged pivotably against a housing part. The input element has a cavity, in which a detent curve body is movably arranged. One end face of the detent curve body has a detent curve, which is pressed against a detent projection on the carrier by a spring acting on the detent sleeve body in the axial direction of the input element. The other end face of the detent curve body has one or more mouldings, which can be inserted into a recess of the housing part by an axial displacement of the detent curve body against the input element.

Description

Eingabeeinheit für ein druck- und drehbetätigbares Bedienelement  Input unit for a pressure- and rotary-actuated operating element
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 Many controls, especially those in motor vehicles, are nowadays assigned several functions. As an example, be one
Lenkradbedienelement mit einem Drehrändel genannt, das unbegrenzt drehbar ist und das zusätzlich eine oder mehrere druckbetätigbare Steering wheel control element with a rotary handle called, which is infinitely rotatable and in addition one or more druckbetätigbare
Schaltfunktionen aufweist. Um Fehlbedienungen zu vermeiden, ist es erwünscht, dass verschiedene Betätigungsarten nicht gleichzeitig ausgeführt werden können. Has 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 10 201 1 103 670 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 Such a pressure and drehbetätigbares control element is known for example from German patent application DE 10 201 1 103 670 A1. 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 rotary sensor, implemented for example by a code disk and a
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 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 used as a microswitch or as a switching dome
Domschaltmatte ausgeführt sein. Domschaltmatte be executed.
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 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
aufeinanderfolgenden Raststufen. Bei einer Druckbetätigung des successive latching steps. At a push of the
Eingabeelements fährt der Hebel gegen einen Anschlag und verhindert durch eine Blockierung des Rastrads die gleichzeitige Ausführung einer Input element moves the lever against a stop and prevented by blocking the ratchet wheel, the simultaneous execution of a
Drehbetätigung. Umgekehrt lenken bei einer Drehbetätigung die Erhebungen der Rastkurve am Rastrad den Hebel aus, wodurch eine gleichzeitige  Rotating operation. Conversely, in a rotary actuation, the elevations of the latching cam on the ratchet wheel deflect the lever, whereby a simultaneous
Druckbetätigung unterbunden wird. Nachteilig an dieser vorbekannten Eingabeeinheit ist, dass das Rastrad und der zugeordnete Rasthebel einen vergleichsweise großen Bauraum benötigen. Pressing is prevented. 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 This object is achieved in that the
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 Rasthülsenkörper 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. Input member has a cavity in which a latching cam is slidably disposed, that an end face of the locking cam has a latching cam, which is pressed by a force acting in the axial direction of the input element on the Rasthülsenkörper spring against a latch on the carrier, and that the other end face of the locking cam 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 The connected to the front side of the locking cam body or molded thereon locking cam and the movable arrangement of the
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. Locking curve body in a cavity of the input element allow a very compact design of the input unit, especially there no Installation space for a ratchet next to the input element must be provided.
Im Folgenden soll der Aufbau und die Funktionsweise einer The following is the structure and operation of a
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 Input unit according to the invention will be explained in more detail with reference to an embodiment sketched in the drawing. Figures 1, 3 and 5 each show a sectional view through an input unit, in
verschiedenen Betätigungszuständen. Die neben den Schnittansichten angeordneten Figuren 2, 4 und 6 zeigen jeweils eine zum jeweiligen different operating states. The arranged next to the sectional views Figures 2, 4 and 6 each show one to each

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 FIG. 1 shows a sectional view through an input unit as part of a pressure- and rotationally actuatable operating element, as may be used, for example, on the steering wheel of a motor vehicle. Of the
Bedienelement ist somit lediglich die Eingabeeinheit dargestellt, die ein auf einem Träger 2 angeordnetes und gegen ein Gehäuseteil 3 verschwenkbar angeordnetes Eingabeelement 1 aufweist. Operating 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.

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.

Wie die Figur 1 zeigt, bildet das Innere des Eingabeelements 1 einen As shown in FIG. 1, the interior of the input element 1 forms a
Hohlraum 14 aus, in dem ein Rastkurvenkörper 10 verschiebbar angeordnet ist. Der Rastkurvenkörper 10 weist an einer Stirnseite eine angeformte Cavity 14, in which a latching cam 10 is slidably disposed. The latching cam 10 has an integrally formed on one end face
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. Die mit dem Rastkurvenkörper 10 verbundene oder daran angeformte  Locking curve 4 and on the opposite end face several projections 7. As illustrated in FIG. 2, the projections 7 are designed to be pin-shaped and are aligned symmetrically and parallel to the shaft 9. The connected to the locking cam 10 or molded on it
Rastkurve 4 bildet eine Vielzahl regelmäßiger Erhöhungen und Vertiefungen aus, an denen eine am Träger 2 angeordnete Rastnase 5 anliegt. Die  Locking cam 4 forms a plurality of regular elevations and depressions on which a arranged on the carrier 2 locking lug 5 is applied. The
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). Locking cam 4 is loaded by a compression spring 6, which is supported on the input element 1 and the locking cam 4 presses against the locking lug 5. In the figure 1, the position of the detent 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 In a rotary actuation of the input element 1, symbolically indicated by the curved double arrow shown in Figure 4, the input element 1 rotates the locking cam 10 with it, so that the latching cam 4 is guided on the arranged on the carrier 2 locking lug 5 along. Since doing the locking lug 5 always at the elevations and depressions of
Rastkurve 4 anliegt, bewegt sich der Rastkurvenkörper 10 in axialer Richtung entlang der Welle 9 vor und zurück (Figur 3). Latching cam 4 is applied, the locking cam 10 moves in the axial direction along the shaft 9 back and forth (Figure 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 1 1 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 Already in the neutral position (Figure 1), wherein the latching nose 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 1 1 of the housing part 3 is relatively small, in particular less than that Height of the elevations of the latching cam 4. Is thus during a rotary actuator (Figure 4) one of the elevations of the latching cam 4 on the locking lug 5, so is the
Rastkurvenkörper 10 soweit gegen die Feder 6 verschoben, dass dessen Anformungen 7 in eine Ausnehmung 8 im Wandabschnitt 1 1 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 Locking cam 10 so far moved against the spring 6, that its projections 7 engage in a recess 8 in the wall portion 1 1 (Figure 3). Since this takes place 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 movement
Verschiebebewegung des Trägers 2. Ohne eine Drehbetätigung greift die Rastnase 5 in eine Vertiefung der Moving movement of the carrier 2. Without a rotary operation engages the locking lug 5 in a recess of the
Rastkurve 4 ein, wodurch die Anformungen 7, wie in den Figuren 1 und 5 dargestellt, noch vor dem Wandabschnitt 1 1 enden und ein Verschieben oder Verschwenken des Trägers 2 durch eine Druckbetätigung nicht blockieren. Erfolgt eine Druckbetätigung durch eine Krafteinwirkung auf das Locking cam 4, whereby the projections 7, as shown in Figures 1 and 5, even before the wall portion 1 1 ends and not block a displacement or pivoting of the carrier 2 by a pressure actuation. Is a pressure operation by a force on the
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 1 1 . Da der Abstand zwischen den Anformungen 7 und dem massiven Teil des Wandabschnitts 1 1 geringer ist als die Höhe der Erhebungen der Rastkurve 4, gelingt es jetzt nicht mehr, durch eine Drehung des Eingabeelements 1 die Erhebungen der Rastkurve 4 an der Rastnase 5 vorbeizubewegen, da die Anformungen 7 bereits vorher auf den Input element 1, the carrier 2 moves with the input element 1 in Direction to the housing part 3. As the figures 5 and 6 show, then at least some of the projections 7 are located below the recess 8 of the wall portion 1 first Since the distance between the projections 7 and the solid part of the wall portion 1 1 is less than the height of the elevations of the latching cam 4, it is no longer possible to move by a rotation of the input element 1, the elevations of the latching cam 4 on the locking lug 5, since the moldings 7 before on the
Wandabschnitt 1 1 treffen und die Verschiebung des Rastkurvenkörpers 10 gegen das Eingabeelement 1 aufhalten. Dadurch wird bei einer Make wall section 1 1 and stop the displacement of the detent cam 10 against the input element 1. This is at a
Druckbetätigung des Eingabeelements 1 eine gleichzeitige Drehbewegung blockiert. Pressing the input member 1 blocks a simultaneous rotational movement.
Derartige Bedienelemente können vorzugsweise in Kraftfahrzeugen zur Anwendung kommen und insbesondere als Koppelelemente in Such controls may preferably be used in motor vehicles and in particular as coupling elements in
Lenkradbedienschaltern, Mittelkonsolen und Armaturenbretter eingesetzt werden. Steering wheel control switches, center consoles and instrument panels are used.
