A control element for a motor vehicle is disclosed that includes at least one rotary actuator and one actuating element integrated in the rotary actuator, whereby the actuating element can be moved relative to the rotary actuator, and whereby a connecting member, which interacts with an optical system, is molded to the actuating element. A connecting member extends into the optical system such that the deflection of the actuating element can be evaluated as a signal by the optical system. The optical system includes at least one light-emitting and at least one light-absorbing light guide element, whereby one light guide element is arranged on one side of the connecting member and one light guide element is arranged outside the connecting member so that a deflection of the actuating element is analogous to the absorption of light.

Description

Dreh- und/oder Drucksteller mit einem in beliebige Richtungen bewegbaren, in der Mitte des Dreh- und/oder Druckstellers angeordneten Stellelementes, insbesondere eines Joysticks, der im Dreh- und/oder Drucksteller schwenkbar aufgenommen und mittels eines zwischen dem Dreh- und/oder Druckstellers und dem Stellelement angeordneten Federelements positionierbar ist.Rotary and / or pressure plate with a movable in any direction, arranged in the center of the rotary and / or pressure actuator actuator, in particular a joystick which is pivotally received in the rotary and / or pressure plate and by means of a between the rotational and / or Pressure actuator and the actuator arranged spring element is positionable.

Aus der unveröffentlichten deutschen Patentanmeldung DE 103 42 335 ist ein mit einem Joystick versehener Dreh- und/oder Drucksteller bekannt. Bei diesem Dreh- und/oder Drucksteller mit Joystickfunktion handelt es sich um einen Dreh- und/oder Drucksteller, in den mittig ein Joystick integriert ist. Der Joystick ist schwenkbar im Dreh-Druckschalter aufgenommen und relativ zum Dreh- und/oder Drucksteller bewegbar. Mittels einer Druckfeder, die zwischen dem Dreh- und/oder Drucksteller und einer an den Joystick angeformten Kulisse angeordnet ist, ist der Joystick relativ zum Dreh- und/oder Drucksteller positionierbar. Hierbei wirkt die Druckfeder nicht unmittelbar auf die Kulisse sondern übt ihre Kraft auf einen Rastring aus, der in einer Nut der Kulisse des Joysticks geführt ist. Bei einer Auslenkung des Joysticks aus der Mittelposition wird der Rastring aus seiner Nut heraus bewegt und mittels der Federkraft, springt der Rastring nach dem Betätigen des Joysticks wieder in die Nut zurück. Das Dokument DE 10160389 offenbart auch ein Dreh und/oder Drucksteller mit Joystickfunktion.From the unpublished German patent application DE 103 42 335 is a provided with a joystick rotary and / or pressure plate known. This rotary and / or pressure actuator with joystick function is a rotary and / or pressure actuator, in the center of which a joystick is integrated. The joystick is pivotally received in the rotary pressure switch and movable relative to the rotary and / or pressure plate. By means of a compression spring, which is arranged between the rotary and / or pressure plate and an integrally formed on the joystick backdrop, the joystick is positioned relative to the rotary and / or pressure plate. Here, the compression spring does not act directly on the backdrop but exerts its force on a locking ring, which is guided in a groove of the scenery of the joystick. With a deflection of the joystick from the center position of the locking ring is moved out of its groove and by means of the spring force, the locking ring jumps back after pressing the joystick back into the groove. The document DE 10160389 also discloses a rotary and / or pressure plate with joystick function.

Aufgabe der Erfindung ist es, eine Fixierung und Positionierung für einen Joystick zu realisieren, die den Joystick zum einen sicher positioniert und darüber hinaus ein definiertes Rasten ermöglicht. Weiterhin soll mittels der federnden Aufnahme die Haptik am Joystick leicht einstellbar sein.The object of the invention is to realize a fixation and positioning for a joystick, which securely positions the joystick on the one hand and also allows a defined locking. Furthermore, the haptic on the joystick should be easily adjustable by means of the resilient recording.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Federelement fest mit dem Dreh- und/oder Drucksteller verbunden ist und dass das Federelement aus mindestens acht zungenartigen Federn gebildet ist, die in einer in das Stellelement eingeformte Nut ein- und ausrastbar sind. Durch die erfindungsgemäße Ausgestaltung der Federelemente ist nun die Möglichkeit geschaffen, eine sehr genaue und sichere Fixierung des Joysticks zu ermöglichen und darüber hinaus über die Position und Anzahl der zungenartigen Federn die Haptik am Joystick definiert einzustellen.This object is achieved in that the spring element is firmly connected to the rotary and / or pressure plate and that the spring element is formed from at least eight tongue-like springs in a in the control element molded groove can be engaged and disengaged. The inventive design of the spring elements, the possibility is now created to allow a very accurate and secure fixation of the joystick and set beyond the position and number of tongue-like springs defined the haptic on the joystick.

Die Erfindung wird nachfolgend anhand einer Zeichnung in einem Ausführungsbeispiel beschrieben.

Figur 1
zeigt einen Schnitt durch ein Bedienelement, dass zum Beispiel in einem Kraftfahrzeug einsetzbar ist.
The invention will be described below with reference to a drawing in an embodiment.
FIG. 1
shows a section through a control that is used for example in a motor vehicle.

In der Figur 1 ist ein Bedienelement 1 in einem Schnittbild dargestellt. Das Bedienelement 1 besteht dabei aus einem Dreh- und/oder Drucksteller 2, dass in diesem Ausführungsbeispiel kreisringförmig ausgebildet ist. In der Mitte des Drehstellers ist eine Öffnung 3 vorgesehen, durch die ein Stellelement 4 in Form eines Joysticks in den Dreh- und/oder Drucksteller 2 hineinreicht. An das Stellelement 4 ist eine Umlenkachse 5 angebaut, die in einer Führungsachse 6 schwenkbar gelagert ist. An die Umlenkachse 5 ist eine Kulisse 8 einstückig angeformt oder angebaut, die sich unterhalb des Dreh- und/oder Druckstellers 2 erstreckt. Oberhalb der Kulisse 8 sind an die Kulisse 8 Schrägen 9 angeformt oder wiederum angebaut, die sich wie die Kulisse 8 umfänglich im Bedienelement 1 erstrecken. In die Schrägen 9 sind Nuten eingeformt, in die wiederum löffelartig endende Zungen 11 eines zylindrischen Federelementes 12 hineinragen. Das zylindrische Federelement 12 ist in diesem Ausführungsbeispiel umfänglich fest mit dem Dreh- und/oder Drucksteller 2 verbunden und im oberen Bereich 13 abgewinkelt ausgeführt, so dass das Federelement 12 formschlüssig am Dreh- und/oder Drucksteller 2 anliegt.In the FIG. 1 an operating element 1 is shown in a sectional view. The operating element 1 consists of a rotary and / or pressure plate 2 that is annular in this embodiment. In the middle of the turntable an opening 3 is provided, through which an adjusting element 4 extends in the form of a joystick in the rotary and / or pressure plate 2. To the adjusting element 4, a deflection axis 5 is attached, which is pivotally mounted in a guide shaft 6. To the deflection axis 5, a link 8 is integrally formed or grown, which extends below the rotary and / or pressure plate 2. Above the gate 8 8 bevels 9 are formed on the backdrop or in turn grown, which extend as the backdrop 8 circumferentially in the control element 1. In the bevels 9 grooves are formed, in turn, the spoon-like ending tongues 11 of a cylindrical spring element 12 protrude. The cylindrical spring element 12 is in this embodiment circumferentially fixedly connected to the rotary and / or pressure plate 2 and performed angled in the upper region 13, so that the spring element 12 is positively applied to the rotary and / or pressure plate 2.

Das zylindrische Federelement 12 ist im oberen Bereich 13 umfänglich geschlossen ausgeführt und besitzt in Richtung der Schrägen 9 zungenartige Verlängerungen 11, die im unteren Bereich 14 löffelartig ausgebildet sind. Zur sicheren Führung des Stellelementes 4 sind bevorzugt acht zungenartige Federelemente 11 am Umfang in regelmäßigen Abständen anzuordnen, damit ein Rasten in beliebige Richtungen ermöglicht ist. Es ist erfindungsgemäß aber ebenso vorstellbar und ein bevorzugtes Ausführungsbeispiel bis zu sechzehn Zungen 11 am zylindrischen Federelement 12 anzuordnen. Darüber hinaus ist es vorteilhaft dies zu vierundzwanzig Zungen 11 am Umfang anzuordnen. Durch die Abkantungen des Federelementes 12 im oberen Bereich 13 und den sich vertikal in der Figur 1 nach unten erstreckenden Zungen 11 wird durch das Federelement 12 ein topfförmiges Gebilde mit offenem Boden erzeugt, so dass das zylindrische Federelement 12 auch als Rastfedertopf beschreibbar ist.The cylindrical spring element 12 is executed in the upper region 13 circumferentially closed and has in the direction of the bevels 9 tongue-like extensions 11, which are spoon-shaped in the lower region 14. For safe guidance of the adjusting element 4 eight tongue-like spring elements 11 are preferably to be arranged on the circumference at regular intervals, so that a locking in any direction is possible. However, it is also conceivable according to the invention and a preferred embodiment up to sixteen tongues 11 on the cylindrical spring element 12 to arrange. In addition, it is advantageous to arrange this at twenty-four tongues 11 on the circumference. Due to the folds of the spring element 12 in the upper region 13 and vertically in the FIG. 1 downwardly extending tongues 11, a cup-shaped structure with an open bottom is generated by the spring element 12, so that the cylindrical spring element 12 can also be described as a detent spring cup.

Wird nun der Joystick 4 in Richtung des Pfeils P in beliebige Richtungen ausgelenkt, so schwenkt die Umlenkachse 5 im Lagerpunkt 7 und gleichzeitig schwenkt die Kulisse 8 um den gleichen Betrag. Festzuhalten ist hierbei, dass der Joystick 4 zwar in beliebige Richtungen bewegbar ist, eine Auswertung aber lediglich in bis zu acht Richtungen erfolgt. Durch die Kulisse 8 werden gleichzeitig die Schrägen 9 bewegt, so dass der untere Bereich 14 des zylinderförmigen Federelementes 12 aus der Nut 10 der Schräge 9 ausrastet und so für den Bediener des Stellelementes 4 haptisch erkennbar wird. Durch die Vielzahl der zungenartigen Federn 11 werden einzelne löffelartige untere Bereiche 14 aus der Nut 10 ausrasten und einige nur bereichsweise aus der Nut 10 herausrasten. Somit ist gleichzeitig eine Rückstellkraft für das Stellelement 4 gegeben, so dass das Stellelement 4 sich selbsttätig wieder in die Mittelposition zurückstellt.If now the joystick 4 is deflected in any direction in the direction of the arrow P, then the deflection axis 5 pivots in the bearing point 7 and at the same time the slotted link 8 pivots by the same amount. It should be noted in this case that the joystick 4 is indeed movable in any direction, but an evaluation takes place only in up to eight directions. Through the gate 8, the bevels 9 are simultaneously moved, so that the lower portion 14 of the cylindrical spring element 12 from the groove 10 of the bevel 9 disengages and thus haptically recognizable to the operator of the control element 4. Due to the large number of tongue-like springs 11, individual spoon-like lower regions 14 will disengage from the groove 10 and some will only disengage from the groove 10 in regions. Thus, at the same time a restoring force for the actuator 4 is given, so that the actuator 4 automatically returns to the middle position.

Es wird vorsorglich daraufhin gewiesen, dass in der Figur 1 lediglich ein Ausführungsbeispiel eines erfindungsgemäßen Federelementes 12 dargestellt ist, dass keine beschränkende Wirkung besitzt, es ist somit ebenfalls vorstellbar, den oberen Bereich 13 des zylindrischen Federelementes 12 gerade oder nach außen abgekantet auszuführen. Wesentlich für die Erfindung ist, dass die unteren Bereiche 14 der zungenartigen Federelemente 11 in eine Schrägefläche der Kulisse ein- und ausrastbar gestaltet sind, so dass ein sicheres Führen des Stellelementes 4 und eine definierte Haptik am Stellelement 4 einstellbar ist.It is precautionary pointed out that in the FIG. 1 only one embodiment of a spring element 12 according to the invention is shown that has no restrictive effect, it is therefore also conceivable to perform the upper portion 13 of the cylindrical spring element 12 bent straight or outward. Essential for the invention is that the lower portions 14 of the tongue-like spring elements 11 in a sloping surface of the gate are designed and disengaged, so that a safe guiding of the actuating element 4 and a defined feel on the actuator 4 is adjustable.
