Description

Die Erfindung betrifft ein Drehbedienelement mit einem Bedienelementkörper und einem Drehknopf, der wenigstens um eine Drehachse drehbar gelagert ist, wobei Bedienelementkörper und Drehknopf so zusammenwirken, dass durch Verdrehen des Drehknopfs eine erste zugehörige Schaltfunktion bereitgestellt wirdThe invention relates to a rotary control element with a control element body and a rotary knob which is rotatably mounted at least about an axis of rotation, wherein the control element body and rotary knob cooperate so that by rotation of the rotary knob, a first associated switching function is provided

Es sind Joystick-Bedienelemente bekannt, bei denen ein Schalthebel entlang wenigstens 2 vorgegebenen Richtungen oder frei verschwenkbar ist, bei denen mit Erreichen jeder Endstellung eine Schaltfunktion ausgeführt wird (digitale Schaltfunktion) oder bei denen proportional zur jeweiligen Auslenkung in den zwei zueinander senkrecht stehenden Auslenkrichtungen ein zugehöriges Signal erzeugt wird, das beispielsweise zur Bewegung eines Cursors auf einem zugehörigen Anzeigefeld einer Anzeigevorrichtung verwendet wird. Bei letzterem werden die zugehörigen der Verschwenkung entsprechenden Signale durch eine Potentiometerverstellung oder mittels eines optischen Encoders erzeugt. Die üblichen Joysticks weisen dazu einen zentral angeordneten und mittels eines Kreuzgelenks gelagerten Bedienhebel auf. Zwar ist eine Verkleinerung des Bedienhebels möglich, die Verkleinerungen weisen jedoch den Nachteil auf, dass Sie nur bei direktem Hinblicken zu Ertasten sind, da Sie aufgrund der Verkleinerung nicht umgriffen werden können, können Sie nicht oder zumindest nur eingeschränkt für andere Schaltfunktionen, beispielsweise als Drucktaster, zur Verfügung stehen.There are joystick controls are known in which a shift lever along at least 2 predetermined directions or is free to pivot in which upon reaching each end position, a switching function is performed (digital switching function) or in which proportional to the respective deflection in the two mutually perpendicular deflection directions associated signal is used, for example, is used to move a cursor on a corresponding display panel of a display device. In the latter case, the associated signals corresponding to the pivoting are generated by a potentiometer adjustment or by means of an optical encoder. The usual joysticks have for this purpose a centrally arranged and mounted by means of a universal joint control lever. Although a reduction of the operating lever is possible, but the reductions have the disadvantage that you are only by direct observation to Ertasten, since you can not be embraced due to the reduction, you can not or at least only to a limited extent for other switching functions, such as a push button , be available.

Ein üblicher Joystick ist aus Dokument WO 9 318 475 bekannt.A common joystick is from document WO 9 318 475 known.

Die Erfinder der vorliegenden Erfindung haben jedoch festgestellt, dass der Fahrer eines Kraftfahrzeugs traditionell gewohnt ist, eine Bedienung durch Drehschalter vorzunehmen. Der konventionelle Drehschalter und seine zur Verfügung stehenden Schaltfunktionen reichen jedoch nicht aus, um aus den immer mehr zunehmenden, insbesondere gleichzeitig auf einem Anzeigefeld, Display oder Monitor angezeigten Wahlmöglichkeiten auszuwählen und Eingaben vorzunehmen. Um dem Fahrer und/oder Bediener eine leichtere, das heißt eine so gering wie mögliche Aufmerksamkeit abverlangende, Orientierung bei der Bedienung zu verschaffen, haben sich die Erfinder die Aufgabe gestellt, ausgehend von einem Drehschalter eine Bedien-möglichkeit zu schaffen, wobei gegenüber einem reinen Drehschalter eine verbesserte Funktionalität bereitgestellt wird. Diese Aufgabe wird erfindungsgemäß durch ein Drehdienelement mit Merkmale des Anspruchs 1 gelöst, wobei der Drehknopf in wenigstens einer, im Wesentlichen senkrecht zur Drehachse stehenden Richtung gegenüber dem Bedienelementkörper verschiebbar gelagert ist, wobei wenigstens eine zusätzliche Schaltfunktion bereitgestellt wird. Vorteilhafte Ausgestaltungen sind jeweils Gegenstand der nebengeordneten Ansprüche.However, the inventors of the present invention have found that the driver of a motor vehicle is traditionally accustomed to operating by rotary switches. However, the conventional rotary switch and its available switching functions are not sufficient to select from the more and more increasing, in particular displayed simultaneously on a display panel, display or monitor options and make inputs. To the driver and / or operator to provide a lighter, that is, as low as possible attentive, orientation in the operation, the inventors have taken on the task, starting from a rotary switch to provide a control possibility, with respect to a pure rotary switch an improved Functionality is provided. This object is achieved by a rotary servomechanism with features of claim 1, wherein the knob is slidably mounted in at least one, substantially perpendicular to the axis of rotation relative to the control element body, wherein at least one additional switching function is provided. Advantageous embodiments are the subject matter of the independent claims.

Die Erfindung betrifft ein Drehbedienelement mit einem Bedienelementkörper zur Aufnahme der zugehörigen Schaltelemente, wie beispielsweise optische Encoder. Ferner ist ein Drehknopf vorgesehen. Der erfindungsgemäße Drehknopf ist hinsichtlich seiner Ausgestaltung nicht eingeschränkt. Er umfasst beispielsweise einen zylindrischen Ring und eine den zylindrischen Ring zum Bediener hin abschließende tellerförmige Kappe. Der Ring ist beispielsweise aus haptischen und/oder optischen Gründen verchromt. In dem Drehknopf können ein hinterleuchtbares Symbol und ein zugehöriges Lichtleitelement angeordnet sein. Der Drehknopf ist erfindungsgemäß wenigstens um eine Drehachse drehbar gelagert, wobei Bedienelementkörper und Drehknopf so zusammenwirken, dass durch Verdrehen des Drehknopfs eine erste zugehörige Regel- und/oder Schaltfunktion bereitgestellt wird.The invention relates to a rotary control element with a control element body for receiving the associated switching elements, such as optical encoders. Furthermore, a knob is provided. The rotary knob according to the invention is not limited in terms of its design. It includes, for example, a cylindrical ring and a cylindrical ring towards the operator final plate-shaped cap. The ring is chromed, for example, for haptic and / or optical reasons. In the knob, a backlit icon and an associated light guide can be arranged. The knob is according to the invention rotatably mounted at least about an axis of rotation, wherein the control element body and knob cooperate so that by rotation of the knob a first associated control and / or switching function is provided.

Beispielweise kann ein dem Maß der Drehverstellung entsprechendes, gegebenenfalls proportionales, Ausgangssignal als Regelfunktion erzeugt werden. In einer anderen Ausgestaltung ist eine reine Schaltfunktion vorgesehen, wobei durch ein Hin- und Herbewegen des Drehknopfes ein Umschalten zwischen einer Aus- und Einschaltstellung eines mit dem Drehknopf mechanisch verbundenen Schaltelements bewirkt wird. Neben der Drehverstellung um die Drehachse kann eine Schaltfunktion durch Bewegung des Drehknopfes in einer zur Drehachse parallelen Richtung bereitgestellt werden.For example, a measure of the rotational adjustment corresponding, possibly proportional, output signal can be generated as a control function. In another embodiment, a pure switching function is provided, which is effected by a reciprocation of the rotary knob switching between a off and on position of a mechanically connected to the knob switching element. In addition to the rotational adjustment about the axis of rotation, a switching function can be provided by movement of the rotary knob in a direction parallel to the axis of rotation.

Der erfindungsgemäße Drehknopf zeichnet sich dadurch aus, dass er in wenigstens einer, im Wesentlichen senkrecht zur Drehachse stehenden Richtung gegenüber dem Bedienelementkörper verschiebbar gelagert ist, und somit seine Drehachse parallel verlagert wird. Durch diese Verlagerung wird erfindungsgemäß eine zusätzliche Regel und/oder Schaltfunktion bereitgestellt. Wie zuvor beschrieben, kann ein dem Maß der Verschiebung entsprechendes Ausgangssignal als Steuergröße erzeugt werden. Bei einer reinen Schaltfunktion bewirkt die Verschiebung ein Umschalten zwischen einer Aus- und Einschaltstellung eines mit dem Drehknopf mechanisch verbundenen Schaltelements. Bei einer besonders einfachen Gestaltung wird die Verschiebung des Drehknopfes durch eine Gleitlagerung des Drehknopfes gegenüber dem Bedienelementkörper erreicht.The rotary knob according to the invention is characterized in that it faces in at least one direction substantially perpendicular to the axis of rotation the control element body is slidably mounted, and thus its axis of rotation is displaced parallel. As a result of this displacement, an additional control and / or switching function is provided according to the invention. As described above, an output signal corresponding to the amount of shift can be generated as a control quantity. In the case of a pure switching function, the displacement causes a switching between an off and on position of a switching element mechanically connected to the rotary knob. In a particularly simple design, the displacement of the knob is achieved by a sliding bearing of the knob relative to the control element body.

In einer vorteilhaften Ausgestaltung ist der Drehknopf in zwei, im Wesentlichen senkrecht zur Drehachse stehenden Richtungen gegenüber dem Bedienelementkörper verschiebbar gelagert, wodurch eine Joystick-Funktionalität bereitgestellt wird. Im einfachsten Fall wird so eine Vier-Wege-Verschiebbarkeit des Drehknopfes bereitgestellt.In an advantageous embodiment, the rotary knob is displaceably mounted in two directions substantially perpendicular to the axis of rotation relative to the control element body, whereby a joystick functionality is provided. In the simplest case, such a four-way displacement of the knob is provided.

In einer bevorzugten Ausgestaltung ist der Drehknopf frei in einer zur Drehachse senkrechten Ebene verschiebbar. Joystick-Funktionalität im Sinne der Erfindung meint, dass in Abhängigkeit von der Bewegungsrichtung eine Schaltfunktion bereitgestellt wird. Hierbei ist ein Schaltsignal oder ein zum Betätigungsweg proportionales Signal erzeugbar. Beispielsweise kann eine Verschiebbarkeit in zwei senkrechten Richtungen zur Steuerung von elektrischen Komponenten eines Fahrzeugs verwendet werden, beispielsweise zur Navigation in einem Display. Bei einer freien Verschiebbarkeit in einer zur Oberfläche des Bedienelements horizontalen Ebene eignet sich das erfindungsgemäße Bedienelement als Mausersatz, d.h. als Eingabemittet, um auf einem Anzeigegerät einen Cursor zu bewegen.In a preferred embodiment, the rotary knob is freely displaceable in a plane perpendicular to the axis of rotation. Joystick functionality in the sense of the invention means that a switching function is provided depending on the direction of movement. In this case, a switching signal or a signal proportional to the actuation signal can be generated. For example, a displacement in two perpendicular directions can be used to control electrical components of a vehicle, for example for navigation in a display. In a free displacement in a plane horizontal to the surface of the control element, the control element according to the invention is suitable as a mouse replacement, i. as input means for moving a cursor on a display device.

Zur Bereitstellung der Joystick-Funktionalität ist ein Kreuzgelenk vorgesehen, um die Verschiebung des Drehknopfes auf zugehörige Schalt- oder Regelelemente zu übertragen, die im Bedienelementkörper angeordnet sind.To provide the joystick functionality, a universal joint is provided to transfer the displacement of the knob to associated switching or control elements disposed in the control body.

Der Drehknopf ist mittels Kugellagerung verschiebbar gelagert. Dadurch wird eine reibungsfreie und verschleißarme Lagerung erreicht, die zudem eine einfache freie Verschiebung des Drehknopfs gegenüber dem Bedienelementkörper gestattet.The knob is slidably mounted by means of ball bearings. As a result, a frictionless and low-wear bearing is achieved, which also allows a simple free displacement of the knob relative to the control element body.

Die Lagerung zur Verschiebung des Drehknopfes ist unterhalb des Drehknopfs, bevorzugt innerhalb eines durch den Drehknopf vorgegebenen Hohlraums, angeordnet. Dadurch kann die Lagerung vorteilhaft vor Staub, Reinigungsflüssigkeit und andersartiger Verschmutzung geschützt werden.The bearing for displacing the rotary knob is arranged below the rotary knob, preferably within a cavity predetermined by the rotary knob. As a result, the storage can be advantageously protected from dust, cleaning fluid and other types of contamination.

Bevorzugt sind zudem mechanische Mittel, wie eine Feder, zur Rückstellung des Drehknopfes in eine Ruhestellung vorgesehen. Die Ruhestellung ist eine bezüglich der maximalen Verschiebbarkeit in der jeweiligen Verschieberichtung mittige Stellung, vorteilhaft liegt dabei der Mittelpunkt des Drehknopfes in der Mittelachse und/oder Drehachse des Bedienelements.In addition, mechanical means, such as a spring, are preferably provided for returning the rotary knob to a rest position. The rest position is one with respect to the maximum displaceability in the respective displacement direction central position, advantageously lies the center of the knob in the central axis and / or axis of rotation of the control.

Der Drehknopf ist mit einem im Wesentlichen scheibenförmigen Innenteil versehen, das in einem Käfig verschiebbar aufgenommen ist. Dadurch wird eine kompakte Bauweise erreicht. Scheibenförmig im Sinne der Erfindung ist weit auszulegen, beispielsweise kann das Innenteil sternförmig sein oder lediglich eine flache Ringform aufweisen. Der zentrale Innenteil kann durchbrochen sein und der Lagerung des Kreuzgelenkes dienen. Das imWesentlichen scheibenförmige Innenteil ist gegenüber den in DrehachDas im Wesentlichen scheibenförmige Innenteil ist gegenüber den in Drehachsenrichtung benachbarten Flächen des Käfigs mittels wenigstens drei, bevorzugt gleichmäßig beabstandeten, Kugeln oder Kugelpaaren verschiebbar gelagert. Beispielsweise sind jeweils 3 Kugelpaare gleichmäßig beabstandet über den Umfang des im Wesentlichen scheibenförmigen Innenteils verteilt, das heißt um jeweils 120° um die Drehachse versetzt angeordnet.The knob is provided with a substantially disc-shaped inner part, which is slidably received in a cage. This achieves a compact design. Disc-shaped in the context of the invention is to be interpreted broadly, for example, the inner part may be star-shaped or merely have a flat ring shape. The central inner part can be broken and serve for the bearing of the universal joint. The substantially disc-shaped inner part is displaceable relative to those in rotary axis. The substantially disc-shaped inner part is displaceably mounted with respect to the areas of the cage adjacent to the axis of rotation by means of at least three, preferably evenly spaced, balls or pairs of balls. For example, each 3 pairs of balls evenly distributed over the circumference of the substantially disc-shaped inner part, that is arranged offset by 120 ° about the axis of rotation.

Zum Erreichen einer hohen Festigkeit und Haltbarkeit sind das im Wesentlichen scheibenförmige Innenteil und/oder der Käfig aus einer Zink-Aluminium-Magnesium-Kupfer-(ZAMAK)-Legierung hergestellt. Beispielsweise sind das Innenteil und/oder der Käfig im Zinkdruckgussverfahren hergestellt.To achieve high strength and durability, the substantially disc-shaped inner part and / or the cage are made of a zinc-aluminum-magnesium-copper (ZAMAK) alloy. For example, the inner part and / or the cage are made by zinc die casting.

Aufgrund seiner zusätzlichen Funktionalität findet das erfindungsgemäße Drehbedienelement vorteilhaft bei einem Kraftfahrzeug oder bei einem Haushaltsgerät ("weiße Ware") Anwendung. Da der Bediener meist an eine Bedienung mittels Drehschalter gewöhnt ist, bedarf es keiner Umgewöhnung trotz zusätzlicher Funktionalität durch den erfindungsgemäßen Drehschalter. Andererseits wird der Bedienkomfort gesteigert, da das erfindungsgemäße Bedienelement eine gegenüber einem gewöhnlichen Drehschalter gesteigerte Funktionalität aufweist, die ein Umgreifen zu einem weiteren Bedienelement entbehrlich macht. Diese gesteigerte Funktionalität kann beispielsweise die Cursor-Steuerung auf einer zugehörigen Anzeigeeinrichtung beinhalten.Due to its additional functionality, the rotary control element according to the invention is advantageously used in a motor vehicle or in a household appliance ("white goods") application. Since the operator is usually used to an operation by means of rotary switches, it requires no getting used despite additional functionality by the rotary switch according to the invention. On the other hand, the ease of use is increased because the control element according to the invention has a relation to a conventional rotary switch increased functionality that makes it unnecessary to embrace a further control element. This increased functionality may include, for example, cursor control on an associated display device.

Fig. 1 zeigt einen Teil des Drehknopfs 1 des erfindungsgemäßen Bedienelements. Dem Bediener ist eine tellerförmige Abdeckung 2 zugewandt, der sich ein im Wesentlichen zylindrischer, verchromter Ring 6 als Griffbereich des Drehknopfes 1 zur Bedienerseite hin anschließt. Der dadurch definierte Hohlraum dient der Aufnahme eines Lichtleitelements 6 zur Hinterleuchtung eines in der Abdeckung 2 angeordneten durchscheinenden Symbols oder Designelements. Die Hinterleuchtung erfolgt durch eine nicht näher dargestellte Lichtquelle, die im Bereich des nicht dargestellten Bedienelementkörpers, der sich auf der dem Bediener abgewandten Seite des Drehknopfes 1 (links in Figur 1) befindet, angeordnet ist. Fig. 1 shows a part of the knob 1 of the control element according to the invention. The operator is facing a plate-shaped cover 2, which is followed by a substantially cylindrical, chromed ring 6 as a handle portion of the knob 1 to the operator side. The cavity defined thereby serves to receive a light-guiding element 6 for the backlighting of a translucent symbol or design element arranged in the cover 2. The backlight is carried out by a light source, not shown, in the region of the control element body, not shown, which is located on the side facing away from the operator of the knob 1 (left in FIG. 1 ) is arranged.

Der Hohlraum des Drehknopfes 1 dient der Aufnahme der Lagerung zur Verschiebung des Drehknopfes 1 in einer zu seiner, in etwa in der Papierebene der Figur 1 liegenden Drehachse senkrechten Ebene. Durch die Integration in den durch den Drehknopf 1 vorgegebenen Hohlraum, fällt trotz dieser zusätzlichen Bewegbarkeit keine zusätzliche Bauhöhe an. Die Bewegbarkeit wird durch ein im Wesentlichen scheibenförmiges Innenteil 3 erreicht, das in einem aus der Führungsplatte 4a und dem Führungsblech 4b gebildeten Käfig in beliebige Richtung verschiebbar ist. Die Verschiebebewegung des Drehknopfes 1 wird mittels eines Kreuzgelenkes 5 auf die in dem Bedienelementkörper angeordnete Schalt- oder Regelelemente übertragen. Hierbei werden, je nach gewünschter Funktionalität, aus dem Stand der Technik bekannte Technologien verwendet,The cavity of the knob 1 serves to accommodate the storage for the displacement of the knob 1 in one of his, approximately in the plane of the paper FIG. 1 lying axis of rotation vertical plane. Due to the integration in the predetermined by the knob 1 cavity falls, despite this additional mobility no additional height. The mobility is achieved by a substantially disc-shaped inner part 3, which is displaceable in any direction in a cage formed from the guide plate 4a and the guide plate 4b. The displacement movement of the rotary knob 1 is transmitted by means of a universal joint 5 to the arranged in the control element body switching or control elements. Here, depending on the desired functionality, known from the prior art technologies are used,

Die Anordnung der Komponenten 3, 4a, 4b und 5 des Drehknopfes 1 sind in Figur 2 im zusammengesetzten Zustand gezeigt. Die Führungsplatte 4a und das Führungsblech 4b sind mittels Schnapphaken miteinander verrastet. Der dabei gebildete Käfig dient der Aufnahme des im Wesentlichen scheibenförmigen Innenteils 3. Dessen nahezu verschleiß- und reibungsfreie Verschiebbarkeit wird durch drei Kugelpaare 8 erreicht, die im Detail in Figur 3 gezeigt sind und jeweils um 120° um die Drehachse versetzt angeordnet sind. Das Innenteil 3 dient ebenfalls der Lagerung des Kreuzgelenks 5, mit dessen Hilfe die Verschiebung mechanisch in eine elektrische Schaltoder Regelfunktion umgewandelt wird. Weitere Rastösen des Führungsblechs 4b dienen zur Verrastung mit Rastnasen, die am verchrombaren Ring 7 vorgesehen sind.The arrangement of the components 3, 4a, 4b and 5 of the knob 1 are in FIG. 2 shown in the assembled state. The guide plate 4a and the guide plate 4b are latched together by means of snap hooks. The case formed cage serves to receive the substantially disc-shaped inner part 3. Its almost wear and friction-free displacement is achieved by three pairs of balls 8, which in detail in FIG. 3 are shown and each offset by 120 ° about the axis of rotation. The inner part 3 also serves to support the universal joint 5, with the aid of which the displacement is mechanically converted into an electrical switching or regulating function. Further detent lugs of the guide plate 4b are used for locking with locking lugs, which are provided on the chromed ring 7.

Der Drehknopf 1 ist um seine Mittelachse 9 drehbar und mittels der ineinander gerasteten Führungsteile 4a, 4b in beliebiger Richtung verschiebbar. Die Verschiebung erfolgt hierbei in einer zur Mittelachse 9 senkrechten Ebene, die im Wesentlichen in einer Ebene mit der Abdeckung 2 liegt, so dass sich für den Bediener eine im Wesentlichen,horizontale Verschiebbarkeit bei einer Abordnung des Bedienelements in einer Mittelkonsole eines Kraftfahrzeugs ergibt.The knob 1 is rotatable about its central axis 9 and by means of the interlocked guide parts 4a, 4b in any direction. The displacement takes place here in a direction perpendicular to the central axis 9 level, which is substantially in a plane with the cover 2, so that the operator is a substantially horizontal displaceability results in a secondment of the operating element in a center console of a motor vehicle.

Die Kugel 8 in der zugehörigen Kugelaufnahme 10 bewegen sich gegeneinander und in unterschiedliche Richtungen, wobei die Kugeln 8 aneinander und an den Führungsteilen 4a, 4b anliegen. Die Verschiebbarkeit der Führungsteile 4a, 4b über das feststehende Innenteil 3 wird durch die äußeren Enden 11 des Innenteils 3 begrenzt. The ball 8 in the associated ball seat 10 move against each other and in different directions, the balls 8 abut each other and on the guide parts 4a, 4b. The displaceability of the guide parts 4a, 4b via the fixed inner part 3 is limited by the outer ends 11 of the inner part 3.
