Description

Die Erfindung betrifft ein Bedienelement nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an operating element according to the preamble of the claim 1.

Ein derartiges Bedienelement ist aus der US 5 107 080 A vorbekannt.Such an operating element is from the US 5 107 080 A previously known.

Aus der DE 101 20 691 A1 ist eine Bedieneinheit bekannt, die ein um eine Achse z drehbares Bedienelement aufweist. Dieses Bedienelement ist auch längs dieser Drehachse verschiebbar und in einer Position dieser Achse verrastbar. Das Bedienelement ist außerdem in zumindest einer zu dieser Achse orthogonale Ebene in beliebiger Richtung verschiebbar.From the DE 101 20 691 A1 For example, an operating unit is known which has a control element rotatable about an axis z. This control element is also displaceable along this axis of rotation and locked in a position of this axis. The control element is also displaceable in any direction in at least one plane orthogonal to this axis.

Bei den bekannten Joysticks ist ein Stellhebel entlang wenigstens 2 vorgegebenen Richtungen verschwenkbar. Dabei wird mit Erreichen jeder Endstellung eine Schaltfunktion ausgeführt, zum Beispiel eine digitale Schaltfunktion, oder es wird proportional zur jeweiligen Auslenkung in den zwei zueinander senkrecht stehenden Auslenkrichtungen ein zugehöriges Signal erzeugt, 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 die Verstellung eines optischen Encoders erzeugt. Die üblichen Joysticks weisen zur Bedienung einen Bedienknopf mit einem zentral angeordneten und mittels eines Kreuzgelenks oder in einer Kugel-Pfanne-Lagerung gelagerten Bedienhebel auf. Dieser Aufbau ist vergleichsweise kompliziert, aufgrund der vergleichsweise hohen Anzahl an bewegten Teilen störanfällig und in der Herstellung teuer. Ferner stellt sich das Problem, dass der Verschwenkmechanismus aufgrund der Kippbewegung des Bedienknopfes schwierig vor Eindringen von Reinigungsflüssigkeit und Staub zu schützen ist. Zudem ist der Bedienknopf meist klein und dünn gehalten, um die Verschwenkbewegung nicht zu behindern. Dies hat den Nachteil, dass der Bedienknopf schwer ertastbar ist und nur bei direktem Hinschauen erblickt und dann gegriffen werden kann. Bei der Verwendung in einem Kraftfahrzeug kann dies den Fahrer stören und seine Aufmerksamkeit vom Verkehr ablenken und stellt somit ein Sicherheitsrisiko dar. Zwar könnte der Bedienknopf vergrößert werden, indem dessen Abstand von der umgebenden Blende erhöht wird. Da mit zunehmender Bauhöhe jedoch das Verletzungsrisiko steigt (Kopfaufschlagkriterium) ist diese Vorgehensweise nicht erwünscht.at the known joysticks is a lever along at least 2 given directions swiveled. This is achieved with each end position executed a switching function, for example, a digital Switching function, or it becomes proportional to the respective deflection in the two mutually perpendicular deflection directions associated Signal generated, for example, to move a cursor an associated one Display field of a display device is used. In the latter case be the associated the pivoting signals corresponding to a Potentiometerverstellung or the adjustment of an optical encoder generates. The usual Joysticks have a control knob with a central operation arranged and by means of a universal joint or in a ball-pan storage stored control lever on. This structure is comparatively complicated due to the relatively high number of moving parts susceptible to interference and expensive in production. Furthermore, the problem arises that the Pivoting mechanism due to the tilting movement of the control knob difficult to prevent penetration of cleaning fluid and dust. moreover the control knob is usually kept small and thin to the pivoting movement not to hinder. This has the disadvantage that the control knob hard is tactile and only when looking directly looks and then can be grasped. When used in a motor vehicle This can disturb the driver and distract his attention from traffic, thus halting Security risk. Although could the control knob can be enlarged, by increasing its distance from the surrounding aperture. As with increasing height However, the risk of injury increases (head-breaking criterion) is this procedure is not desired.

Ausgehend von dem Eingabegerät der eingangs genannten Art und vor dem Hintergrund der obigen Nachteile des Standes der Technik haben sich die Erfinder die Aufgabe gestellt, ein Bedienelement der zuvor beschriebenen Gattung bereitzustellen, das zuverlässig, einfach zu bedienen und herzustellen ist. Diese Aufgabe wird durch ein Eingabegerät gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind jeweils Gegenstand der abhängigen Ansprüche.outgoing from the input device of the type mentioned above and against the background of the above disadvantages In the state of the art, the inventors have set themselves the task to provide an operating element of the type described above, that reliable, easy to use and manufacture. This task is done by an input device according to claim 1 solved. Advantageous embodiments are the subject of the dependent claims.

Die Erfindung betrifft ein Bedienelement, bevorzugt ein Bedienelement für ein Kraftfahrzeug. Das Bedienelement umfasst einen Bedienknopf, der mit einer Stellachse verbunden ist. Beispielsweise ist die Stellachse konzentrisch an einem zylindrischen Bedienknopf angebracht und erstreckt sich von dessen dem Bediener abgewandten Stirnseite. Das Bedienelement umfasst zwei verschwenkbare Hebel. Der Begriff Hebel im Sinne der Erfindung ist weit auszulegen und die Hebel können je nach mechanischer Beanspruchung vielfältig ausgelegt sein. Die Stellachse wirkt mit den verschiebbaren Hebeln so zusammen, dass die Hebel entsprechend der Bewegung der Stellachse verschwenkt werden. Beispielsweise ist die Stellachse in wenigstens einer Ausnehmung des Hebels aufgenommen, wobei die Ausnehmung bevorzugt so ausgestaltet ist, dass die Stellachse in der Verschwenkrichtung mit minimalem Spiel aufgenommen ist, um einen „Totgang” zu verhindern. Es sind ferner Mittel zur Detektion der Verschwenkbewegung der Hebel vorgesehen, um die Regel- oder Schaltfunktionen (beispielsweise als Vierwege-Schalter) durchzuführen. Hierbei ist es vorstellbar, dass die Hebel sich ausgehend von der Schwenkachse lediglich bis über die Ausnehmungen erstrecken, so dass die Hebel eine C-Form bilden.The The invention relates to an operating element, preferably an operating element for a Motor vehicle. The operating element comprises a control knob, the connected to a control axis. For example, the positioning axis mounted concentrically on a cylindrical control knob and extends from the end facing away from the operator. The operating element includes two pivotable levers. The term lever in the sense of Invention is widely interpreted and the levers may vary depending on mechanical stress diverse be designed. The adjusting axle works with the sliding levers so together that the levers corresponding to the movement of the adjusting axis be pivoted. For example, the adjusting axis is in at least a recess of the lever received, wherein the recess is preferred is configured so that the adjusting axis in the pivoting direction with minimal play to prevent "backlash". They are further Means for detecting the pivoting movement of the levers provided to perform the control or switching functions (for example as a four-way switch). in this connection It is conceivable that the levers are starting from the pivot axis only until over the recesses extend so that the levers form a C-shape.

Das erfindungsgemäße Bedienelement zeichnet sich dadurch aus, dass die Stellachse achsenparallel verschiebbar gelagert ist. Anders ausgedrückt, die Stellachse wird unter Beibehaltung ihrer Ausrichtung parallel verschoben, um die Regel- oder Schaltfunktionen vorzunehmen. Es erfolgt somit eine translatorische Bedienung der Stellachse und damit auch des Bedienknopfes, das heißt der Bedienknopf wird in seiner Einbaulage, zum Beispiel in einem Armaturenbrett eines Kraftfahrzeuges, in einer zum Armaturenbrett horizontalen Ebene verschoben. Dies hat nicht nur den Vorteil, dass aufgrund der geringen Anzahl an bewegten Teilen und der vereinfachten Lagerung der Stellachse der Aufbau erheblich vereinfacht ist und damit die Herstellung verbilligt wird, sondern dass darüber hinaus aufgrund der reinen translatorischen Bewegung die Problematik der Abdichtung leichter zu lösen ist.The inventive control draws characterized by the fact that the adjusting axis axially parallel displaced is stored. In other words, the adjusting axis becomes parallel while maintaining its orientation moved to perform the control or switching functions. It Thus, a translatory operation of the adjusting axis and so that the control knob, that is, the control knob is in its mounting position, for example in a dashboard of a motor vehicle, moved in a plane horizontal to the dashboard. this has not just the advantage that moving due to the small number of Parts and the simplified storage of the positioning axis of the structure is considerably simplified and thus the production is cheapened, but that about it In addition, due to the pure translational movement, the problem the seal easier to solve is.

Darüber hinaus kann der Bedienknopf flach und trotzdem groß ausgestaltet sein, Um genauer zu sein, er kann unter Einhalt des in vielen Ländern gesetzlich vorgeschriebenen Überstandes von der umgebenden Blende, sofern er in einem Kraftfahrzeug verwendet wird, gemäß seiner haptischen Erfordernisse nahezu beliebig ausgestaltet sein.Furthermore The control knob can be flat and still large, to be more accurate To be, he can stop the supernatant legally required in many countries from the surrounding bezel, if used in a motor vehicle will, according to his Haptic requirements can be designed almost arbitrarily.

Ein weiterer Vorteil ergibt sich dadurch, dass das Spaltmaß zwischen Bedienknopf und einem dem Bedienknopf zugehörigen Gehäuse sehr klein eingestellt werden kann, was einerseits Verschmutzungen vorbeugt und andererseits einen hohen qualitativen Aussehen zu gute kommt.One Another advantage results from the fact that the gap between Control knob and a housing associated with the control knob very small can be, which on the one hand prevents soiling and on the other hand a high qualitative appearance comes to good.

Zum Erhalt einer Regelfunktion erzeugen die Mittel zur Detektion der Verschwenkbewegung jeweils ein der Verschwenkung des betreffenden Hebels im Wesentlichen proportionales Signal.To the Obtaining a control function generates the means for detecting the Pivoting each one of the pivoting of the relevant Lever essentially proportional signal.

In einer besonders einfachen Ausgestaltung umfassen die Mittel zu Detektion jeweils eine dem betreffenden Hebel zugeordnete Widerstandsbahn und jeweils einen an dem Hebel befestigten, und bei der Verschwenkbewegung über die Widerstandsbahn geführten Schleifkontakt. In Abhängigkeit der Stellung des Hebels wird so ein entsprechender Widerstandswert abgegriffen (Potentiometer-Prinzip), der zur Erzeugung eines der Stellung des betreffenden Hebels entsprechenden Signals verwendet wird.In In a particularly simple embodiment, the means comprise detection each one associated with the respective lever resistance path and one each attached to the lever, and in the pivoting movement over the Resistance track guided Sliding contact. Dependent on The position of the lever is thus a corresponding resistance value tapped (potentiometer principle), which is used to generate one of Position of the lever concerned corresponding signal used becomes.

In einer besonders zuverlässigen und präzisen Ausgestaltung umfassen die Mittel zu Detektion jeweils ein mit dem betreffenden Hebel gekoppeltes Drehpotentiometer oder in diesem Sinne noch bevorzugter einen damit gekoppelten optischen Encoder.In a particularly reliable and precise Embodiment comprise the means for detecting each one with the concerned lever coupled rotary potentiometer or in this More preferably, an optical encoder coupled thereto.

Zum Erhalt einer Schaltfunktion erzeugen Mittel zur Detektion der Verschwenkbewegung jeweils ein mit der Verschwenkung korreliertes An- oder Aussignal.To the Receiving a switching function generate means for detecting the pivoting movement in each case one with the pivoting correlated on or off signal.

Die Schaltfunktion kann in einer preiswerten Ausgestaltung durch wenigstens einen mechanischen Schalter pro Hebel realisiert sein. In einer verschleißarmen Ausgestaltung umfassen die Mittel zur Detektion der Verschwenkbewegung jeweils wenigstens eine Lichtschranke, die so angeordnet ist, dass deren Lichtweg durch Verschwenken des betreffenden Hebels abgeschattet werden kann.The Switching function can be in a low-cost configuration by at least be realized a mechanical switch per lever. In a low wear Embodiment comprise the means for detecting the pivoting movement each at least one light barrier, which is arranged so that their Shadowed light path by pivoting the lever concerned can be.

Bevorzugt umfassen die Mittel zur Detektion der Verschwenkbewegung jeweils wenigstens zwei Lichtschranken pro Hebel, um die Richtung der Verschwenkbewegung des betreffenden Hebels, beispielsweise aus seiner Ruhestellung, zu detektieren. Dadurch können pro Hebel drei Schaltzustände realisiert werden: Ruhestellung, Ausschlag in einer erste Richtung und Ausschlag in eine zweite, entgegen gesetzte Richtung.Prefers comprise the means for detecting the pivoting movement respectively at least two photocells per lever, around the direction of the pivoting movement of the lever in question, for example from its rest position, to detect. Thereby can three switching states per lever be realized: rest position, rash in a first direction and rash in a second, opposite direction.

Bevorzugt sind die Schwenkachsen der Hebel um 90° versetzt um eine Ruhestellung der Stellachse angeordnet. Dadurch kann einfach zusammen mit der Erzeugung eines der Verschwenkung des betreffenden Hebels im Wesentlichen proportionalen Signals für jeden Hebel ein Eingabegerät geschaffen werden, dass zur Steuerung eines Cursors oder dergleichen auf einem Anzeigegerät dient. Bei der Ausgestaltung, bei der die Mittel zur Detektion der Verschwenkbewegung jeweils wenigstens zwei Lichtschranken pro Hebel umfassen, können mit der um 90° versetzten Hebelanordnung vergleichsweise einfach, ein 4-Wege-Schalter oder gar ein 8-Wege-Schalter realisiert werden.Prefers are the pivot axes of the lever offset by 90 ° to a rest position the adjusting axis arranged. This can be easy along with the Generating one of the pivoting of the lever in question substantially proportional signal for every lever an input device be created that to control a cursor or the like on a display device serves. In the embodiment in which the means for detecting the Swiveling movement in each case at least two light barriers per lever may include with the offset by 90 ° Lever arrangement comparatively simple, a 4-way switch or even an 8-way switch can be realized.

Bevorzugt sind Mittel zur Rückstellung der Hebel und damit der Stellachse in die Ruhestellung vorgesehen. Beispielsweise sind Federn zur Rückstellung der Hebel vorgesehen.Prefers are means of provision the lever and thus the adjusting axis provided in the rest position. For example, springs are for restoring provided the lever.

In einer weiteren Ausgestaltung ist vorgesehen, dass die Stellachse zur Durchführung einer zusätzlichen Schalt- und/oder Regelfunktion um ihre Achse drehbar oder in Achsenrichtung verschiebbar ist und dass sie auf ein zugehöriges Schalt- oder Regelglied, beispielsweise ein Drehpotentiometer oder einen optischen Encoder für die Regelfunktion oder einen Tastschalter für die Schaltfunktion, einwirkt. Diese zusätzliche Funktionalität ist aufgrund des einfachen Aufbaus und der reinen translatorischen Bewegung der Stellachse besonders leicht in die erfindungsgemäße Ausgestaltung zu integrieren.In A further embodiment provides that the adjusting axis to carry out an additional one Switching and / or regulating function rotatable about its axis or in the axial direction is displaceable and that it is related to an associated switching or control element, For example, a rotary potentiometer or an optical encoder for the Control function or a push-button switch for the switching function, acts. These additional functionality is due to the simple structure and the pure translational Movement of the adjusting axis particularly easy in the inventive design to integrate.

Zum Erreichen einer hohen Festigkeit und Haltbarkeit sind wenigstens die Hebel und/oder die Stellachse aus einer Zink-Aluminium-Magnesium-Kupfer-(ZAMAK)-Legierung, beispielsweise in einem Zinkdruckgussverfahren, hergestellt.To the Achieving high strength and durability are at least the levers and / or the adjusting axis of a zinc-aluminum-magnesium-copper (ZAMAK) alloy, for example in a zinc die casting process.

Aufgrund der Möglichkeit einen Bedienknopf vorzusehen, der haptisch gut zu ergreifen ist und zudem einen geringen Überstand aufweisen kann und da die zugehörige Mechanik gegenüber Eindringen von Reinigungsflüssigkeit und Staub leicht abzudichten ist, findet das erfindungsgemäße Bedienelement vorteilhaft bei einem Kraftfahrzeug Anwendung.by virtue of The possibility to provide a control knob that is easy to take haptic and also a small supernatant may have and as the associated Mechanics opposite Penetration of cleaning fluid and dust is easy to seal, the control element according to the invention is advantageous in a motor vehicle application.

In der beigefügten Figur ist eine bevorzugte Ausführungsform der wesentlichen Elemente der Mechanik des erfindungsgemäßen Bedienelements schematisch dargestellt, ohne die Erfindung darauf zu beschränken.In the attached Figure is a preferred embodiment the essential elements of the mechanics of the control element according to the invention schematically illustrated without limiting the invention thereto.

Das Bedienelement 1 umfasst einen Bedienknopf 2 der mit einer Stellachse 6 starr verbunden ist. Die Stellachse 6 greift jeweils in längliche Ausnehmungen 9 zweier Schenkel eines Hebels 5 und entsprechend in die Ausnehmung eines weiteren Hebels 4 ein, wobei die Hebel 4, 5 um jeweils zugehörige, an einer Grundplatte 8 befestigte Schwenkachsen 3 verschwenkbar gelagert sind. Die Schwenkachsen sind um 90° um die Stellachse 6 versetzt angeordnet. Die Ausnehmungen 9 sind so dimensioniert, dass deren Rand in einer Verschwenkrichtung möglichst spielfrei an der Stellachse 6 anliegt, andererseits deren Längsausdehnung so bemessen ist, dass das Bewegungsmaß der Stellachse in Verschwenkrichtung des jeweils anderen Hebels 4 bzw. 5 ausreichend gestattet ist. Die Verschwenkbewegung der Hebel 4, 5, die durch den Bedienknopf 2 über die Stellachse 6 bewirkt wird, wird durch nicht dargestellte Mittel zur Detektion der Verschwenkbewegung detektiert. Beispielsweise ist auf der Grundplatte 8 je eine dem betreffenden Hebel 4, 5 zugeordnete Widerstandsbahn vorgesehen, die von einem Schleifkontakt bei der Verschwenkbewegung abgefahren wird, um ein der Verschwenkstellung entsprechenden Widerstandswert und damit ein dazu proportionales Signal zu erzeugen. In einer weiteren Ausgestaltung kann vorgesehen sein, dass die Stellachse 6 zur Vornahme einer zusätzlichen Schalt- und/oder Regelfunktion durch den Bedienknopf 2, um ihre Achse drehbar oder in Richtung ihrer Längsachse verschiebbar ist und dass sie auf ein zugehöriges Schalt- oder Regelglied, beispielsweise ein Drehpotentiometer oder einen optischen Encoder für die Regelfunktion oder einen Tastschalter für die Schaltfunktion, einwirkt. Diese zusätzliche Funktionalität ist aufgrund des einfachen Aufbaus und der reinen translatorischen Bewegung der Stellachse 6 besonders leicht in die erfindungsgemäße Ausgestaltung zu integrieren.The operating element 1 includes a control knob 2 the one with a control axis 6 is rigidly connected. The adjusting axle 6 engages in elongated recesses 9 two legs of a lever 5 and correspondingly in the recess of another lever 4 one, with the levers 4 . 5 in each case, on a base plate 8th fixed pivot axes 3 are pivotally mounted. The swivel axes are 90 ° around the positioning axis 6 staggered. The recesses 9 are dimensioned so that their edge in a pivoting as possible clearance on the adjusting axis 6 on the other hand, whose longitudinal extent is dimensioned so that the amount of movement of the adjusting axis in the pivoting of the each other lever 4 respectively. 5 is sufficiently permitted. The pivoting movement of the lever 4 . 5 by the control knob 2 over the adjusting axle 6 is detected is detected by means not shown for detecting the pivoting movement. For example, on the base plate 8th one each to the relevant lever 4 . 5 associated resistive path provided, which is traversed by a sliding contact during the pivoting movement to generate a pivoting position corresponding resistance value and thus a signal proportional thereto. In a further embodiment, it can be provided that the adjusting axle 6 to perform an additional switching and / or control function by the control knob 2 is rotatable about its axis or displaceable in the direction of its longitudinal axis and that it acts on an associated switching or control element, such as a rotary potentiometer or an optical encoder for the control function or a push-button switch for the switching function. This additional functionality is due to the simple structure and the pure translational movement of the adjusting axis 6 particularly easy to integrate in the inventive design.
