Description

Die Erfindung betrifft ein druck- und drehbetätigbares Bedienelement, mit einem Betätigungselement, welches mittels einer Lagerwelle an einem Lagerbock drehbar gelagert ist, mit wenigstens einem Schaltelement, welches durch eine Druckbetätigung des Betätigungselements betätigbar ist, mit einem Sensorelement zur Erfassung einer Drehbetätigung des Betätigungselements, mit einem mit der Lagerwelle verbundenen Rastrad, und mit einem federbelastetem Rastelement, welches mit einer Rastkontur des Rastrads zusammenwirkt und bei einer Druckbetätigung des Betätigungselements dessen Drehbeweglichkeit aufhebt.The invention relates to a pressure and drehbetätigbares operating element, with an actuating element which is rotatably supported by a bearing shaft on a bearing block, with at least one switching element which is actuated by a pressure actuation of the actuating element, with a sensor element for detecting a rotary actuation of the actuating element, with a latching wheel connected to the bearing shaft, and with a spring-loaded latching element, which cooperates with a latching contour of the latching wheel and reverses its rotational mobility in a pressure actuation of the actuating element.

Bei einer aus der deutschen Offenlegungsschrift DE 197 15 360 A1 bekannten Bedienvorrichtung ist ein als Walzenrändel ausgebildetes Betätigungselement auf einem Lagerbock drehbar gelagert. Mit Hilfe von Klipsen haltert der Lagerbock zudem eine Leiterplatte, wobei die Leiterplatte von Zapfen, die am Lagerbock angeformt sind, durchdrungen wird. Der Lagerbock und die Leiterplatte sind somit gegeneinander unbeweglich miteinander verbunden. Des Weiteren ist das Betätigungselement hinsichtlich von Bewegungen senkrecht zu seiner Drehachse gegenüber dem Lagerbock und dem Schaltungsträger unverschieblich angeordnet. Um eine Druckbetätigung des Betätigungselements auf ein Schaltelement übertragen zu können, stützt sich das am Schaltungsträger angeordnete Schaltelement gegen ein separates Gehäuse ab. Die aus Betätigungselement, Lagerbock und Leiterplatte montierte Baugruppe ist gegenüber diesem Gehäuse beweglich gelagert.In one from the German patent application DE 197 15 360 A1 known operating device designed as a roller knurl actuator is rotatably mounted on a bearing block. With the help of clips, the bearing block also holds a printed circuit board, wherein the circuit board is penetrated by pins which are integrally formed on the bearing block. The bearing block and the circuit board are thus immovably connected to each other. Furthermore, the actuating element with respect to movements perpendicular to its axis of rotation relative to the bearing block and the circuit carrier is arranged immovable. In order to be able to transmit a pressure actuation of the actuating element to a switching element, the switching element arranged on the circuit carrier is supported against a separate housing. The assembled from actuator, bracket and PCB assembly is movably mounted relative to this housing.

Diese Bedienvorrichtung weist ein drehfest mit dem Betätigungselement verbundenes Rastrad auf, welches Ausnehmungen besitzt, in das, bei einer Druckbetätigung des Betätigungselements, eine federbelastete Raste eindringt und so dessen Drehbeweglichkeit blockiert. Ohne eine Druckbetätigung ist die Drehbeweglichkeit des Betätigungselements nicht durch das Rastrad beeinflusst.This operating device has a non-rotatably connected to the actuating element ratchet, which has recesses into which, at a pressure actuation of the actuating element, a spring-loaded detent penetrates and thus blocks its rotational mobility. Without one Push operation, the rotational movement of the actuator is not affected by the ratchet wheel.

Für manche Anwendungen ist es erwünscht, dass ein drehbetätigtes Bedienelement erkennbare Raststufen aufweist. Hierfür wird beispielsweise ein Rad mit einer wellenförmigen Rastkontur vorgesehen, an der ein federbelasteter Rastbolzen anliegt.For some applications, it is desirable that a rotationally actuated operating element has recognizable latching steps. For this purpose, for example, a wheel with a wave-shaped locking contour is provided, against which a spring-loaded locking bolt.

Eine Drehbetätigung des Bedienelements mit Raststufen ist aus der DE 197 15 360 A1 nicht ersichtlich, da die in die Ausnehmungen des Rastrads eingreifende Raste hier nur eine Sperrung oder eine Freigabe des Betätigungselements erlaubt. Zur Erzielung eines rastenden Drehens des Bedienelements wären daher zusätzliche Mittel erforderlich, welche in diesem Dokument nicht offenbart sind. Diese zusätzlichen Mittel würden auch einen zusätzlichen Kostenaufwand und einen zusätzlichen Bauraum erfordern.A rotary operation of the control element with latching steps is from the DE 197 15 360 A1 not visible, since the engaging in the recesses of the ratchet catch allows only a blocking or release of the actuator here. To achieve a locking rotation of the control element therefore additional means would be required, which are not disclosed in this document. These additional resources would also require additional expense and space.

Es stellte sich daher die Aufgabe, ein druck- und drehbetätigbares Bedienelement zu schaffen, das sowohl ein rastendes Drehen als auch eine Sperrung der Drehbewegung bei einer Druckbetätigung realisiert, und sich durch einen platzsparenden und kostengünstigen Aufbau auszeichnet.It was therefore an object to provide a pressure and drehbetätigbares operating element, which realizes both a latching rotation and a blocking of the rotational movement in a pressure actuation, and is characterized by a space-saving and cost-effective design.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Rastelement als ein um ein Drehlager verschwenkbarer Hebel ausgebildet ist, der einen an der Rastkontur anliegenden Rastbolzen aufweist, und dass eine Druckbetätigung des Betätigungselement einen Abschnitt des Hebels einem Gegenstand annähert, der den Verschwenkbereich des Hebels begrenzt.This object is achieved in that the locking element is designed as a pivotable about a pivot lever, which has a voltage applied to the locking contour detent pin, and that a pressure actuation of the actuating element approximates a portion of the lever an object that limits the pivoting range of the lever.

Der verschwenkbare Hebel erfüllt dabei zwei Funktionen auf vorteilhafte Weise. Indem er einen Rastbolzen ausbildet, der federbelastet an der wellenförmigen Rastkontur des Rastrades anliegt, bewirkt er eine Schalthaptik, bei der bei einer Drehbetätigung des Betätigungselements fühlbare Raststufen erkennbar sind.The pivotable lever fulfills two functions in an advantageous manner. By forming a latching pin, which bears spring-loaded on the wave-shaped latching contour of the ratchet wheel, it causes a switching feel, can be seen in the case of a rotary actuation of the actuating element sensible latching steps.

Eine Druckbetätigung des Betätigungselements verschiebt den Lagerbock und den daran gelagerten Hebel, bis der Hebelarm auf einen festen Gegenstand, wie etwa auf den Schaltungsträger oder ein Gehäuseteil des Bedienelements trifft oder sich zumindest dicht annähert. Hierdurch liegt der Rastbolzen unverschieblich am Rastrad an und blockiert das Rastrad durch das kraftschlüssige Eingreifen in die Rastkontur. Der Rastbolzen ermöglicht so eine Sperrung der Drehfunktion während der Betätigung der Druckfunktion und umgekehrt.A push of the actuator displaces the bearing block and the lever mounted thereon until the lever arm encounters or at least closely approaches a solid object, such as the circuit carrier or a housing part of the operating element. As a result, the locking pin is immovably on the ratchet wheel and blocks the ratchet wheel by the frictional engagement in the locking contour. The locking pin thus allows blocking the rotation function during the operation of the printing function and vice versa.

Vorteilhaft ist es, wenn die Sensorik für die Drehfunktion sich auf einer separaten Leiterplatte befindet, die flexibel oder starr ausgeführt sein kann und mit dem Betätigungselement in einer Baugruppe integriert ist. Die Sensorik der Drehfunktion kann dadurch von der Sensorik der Druckfunktion mechanisch weitgehend entkoppelt werden. Hierdurch ist ein relativ großer Hub für die Druckfunktion umsetzbar.It is advantageous if the sensors for the rotary function is located on a separate printed circuit board, which may be flexible or rigid and is integrated with the actuating element in an assembly. The sensor technology of the rotary function can thereby be largely mechanically decoupled from the sensor technology of the printing function. As a result, a relatively large stroke for the printing function can be implemented.

An embodiment of the invention is illustrated below with reference to a drawing and explained in more detail. Show it:

Die Figur 1 zeigt ein druck- und drehbetätigbares Bedienelement in einer isometrischen Darstellung. Das Bedienelement weist ein im Wesentlichen zylinderförmiges Betätigungselement 1 auf, welches auf einer Lagerwelle 2 sitzt, die an einem Lagerbock 3 drehbar gelagert ist. Der Lagerbock 3 ist in einen Gehäuse 4 linear beweglich geführt, so dass der Lagerbock 3 bei einer Druckbetätigung des Betätigungselements 1 gegen das Gehäuse 4 verschiebbar ist. Der Lagerbock 3 stützt sich auf mindestens einem Schaltdom 14 einer Domschaltmatte 13 ab, der bei einer Druckeinwirkung auf das Betätigungselement 1 zusammengepresst wird und dadurch einen nicht dargestellten Schaltkontakt auf einem unterhalb der Domschaltmatte 13 angeordneten Schaltungsträger 12 schließt oder unterbricht, wodurch die Druckbetätigung durch eine hier ebenfalls nicht dargestellte Elektronik sensierbar ist. Als Schaltelement kann statt des Schaltdoms 14 alternativ auch ein Mikrotaster vorgesehen sein.The FIG. 1 shows a pressure and drehbetätigbares control in an isometric view. The control element has a substantially cylindrical actuator 1, which sits on a bearing shaft 2, which is rotatably mounted on a bearing block 3. The bearing block 3 is guided linearly movable in a housing 4, so that the bearing block 3 is displaceable against the housing 4 in a pressure actuation of the actuating element 1. The bearing block 3 is based on at least one switching dome 14 of a Domschaltmatte 13, which is compressed at a pressure on the actuator 1 and thereby closes a switch contact, not shown on a arranged below the Domschaltmatte 13 circuit substrate 12 or interrupts, whereby the pressure actuation by a here also not shown electronics is sensed. As a switching element instead of the switching dome 14 may alternatively be provided a micro-probe.

Ein weiterer Schaltungsträger, ausgeführt als eine flexible oder starre Leiterplatte 5 ist am Lagerbock 3 zur elektrischen Anbindung eines Sensorelements 6 angeordnet, welches Drehbewegungen des Betätigungselements 1 erfasst. Hierzu sitzt auf der Lagerwelle 2 des Betätigungselements 1 ein Signalgeber 8, der hier rein beispielhaft als flügelradartige Codescheibe ausgebildet ist, und der mit einem optischen Sensorelement 6 in Form einer Gabellichtschranke zusammenwirkt. Selbstverständlich kann die Sensorik zur Erfassung der Drehbetätigung des Betätigungselements 1 auch nach einem anderen Messprinzip funktionieren, beispielsweise indem ein magnetfeldsensierendes Hallelement die Drehstellung eines Magnetrades erfasst.Another circuit carrier, designed as a flexible or rigid circuit board 5 is arranged on the bearing block 3 for the electrical connection of a sensor element 6, which detects rotational movements of the actuating element 1. For this purpose, sits on the bearing shaft 2 of the actuating element 1, a signal generator 8, which is formed here purely by way of example as Flügelradartige code disc, and which cooperates with an optical sensor element 6 in the form of a fork light barrier. Of course, the sensor system for detecting the rotational actuation of the actuating element 1 can also function according to another measuring principle, for example by detecting a magnetic field-sensing Hall element, the rotational position of a magnetic wheel.

Zwischen dem Betätigungselement 1 und der Codescheibe 8 ist in der Figur 1 ein Rastrad 7 mit einer entlang des Umfangs verlaufenden wellenförmigen Rastkurve 15 erkennbar. Wie die Querschnittsansicht der Figur 2 verdeutlicht, ist das Rastrad 7 mit der Lagerwelle 2 verbunden. Unterhalb des Rastrades 7 ist am Gehäuse 4 eine Feder 10 gelagert, die einen Rastbolzen 16 gegen die Rastkurve 15 des Rastrades 7 presst.Between the actuator 1 and the code disk 8 is in the FIG. 1 a ratchet wheel 7 with a circumferentially extending wavy locking curve 15 recognizable. Like the cross sectional view of the FIG. 2 illustrates, the ratchet wheel 7 is connected to the bearing shaft 2. Below the ratchet wheel 7, a spring 10 is mounted on the housing 4, which presses a locking pin 16 against the latching cam 15 of the ratchet wheel 7.

In der Figur 3, die einen Querschnitt durch das Rastrad 7 und den Rastbolzen 16 zeigt, ist ersichtlich, dass der Rastbolzen 16 einstückig mit einem Hebel 9 ausgebildet ist, der mit einem Endabschnitt um ein Drehlager 17 am Lagerbock 3 verschwenkbar gelagert ist. Aufgrund der Lagerung an einem seiner Endabschnitte bildet der Hebel 9 einen im physikalischen Sinne einarmigen Hebel aus. In einem mittleren Bereich weist der Hebel 9 den ungefähr senkrecht zu seiner Erstreckungsrichtung angeformten Rastbolzen 16 auf, der von der auf die Unterseite des Hebels 9 einwirkenden Feder 10 gegen die Rastkurve des Rastrades 7 gepresst wird. Der dem Drehlager 17 gegenüberliegende freie Endabschnitt 11 des Hebels 9 steht in der hier dargestellten Stellung des Betätigungselements 1 frei zur Seite ab.In the FIG. 3 showing a cross section through the ratchet wheel 7 and the locking pin 16, it can be seen that the locking pin 16 is integrally formed with a lever 9 which is pivotally mounted with an end portion about a pivot bearing 17 on the bearing block 3. Due to the storage at one of its end portions of the lever 9 forms a one-armed lever in the physical sense. In a central region, the lever 9 has the approximately perpendicular to its extension direction integrally formed locking pin 16 which is pressed by the force acting on the underside of the lever 9 spring 10 against the locking cam 7 of the ratchet wheel. The pivot bearing 17 opposite free end portion 11 of the lever 9 is free in the position shown here of the actuator 1 from the side.

Wird nun das Betätigungselement 1 um die Lagerwelle 2 gedreht, so folgt die vertikale Position des Rastbolzens 16, der aufgrund der auf den Hebel 9 wirkenden Kraft der Feder 10 ständig am Rastrad 7 anliegt, dem Verlauf der Rastkurve 15. Dadurch führt der Hebel eine periodische Schwenkbewegung um das Drehlager 17 aus, die am freien Endabschnitt 11 des Hebels 9 aufgrund der relativ kleinen Auslenkungen als Aufwärts-/Abwärtsbewegung erkennbar ist. Der Kraftaufwand zum Drehen des Betätigungselements variiert ebenfalls mit dem periodischen Verlauf der Rastkurve 15, was haptisch als eine rastende Drehung wahrgenommen wird.Now, if the actuator 1 is rotated about the bearing shaft 2, so follows the vertical position of the locking bolt 16, which constantly rests on the ratchet 7 due to acting on the lever 9 force of the spring 7, the course of the latching cam 15. As a result, the lever performs a periodic Pivoting movement about the pivot bearing 17, which is recognizable at the free end portion 11 of the lever 9 due to the relatively small deflections as upward / downward movement. The force required to rotate the actuator also varies with the periodic nature of the detent curve 15, which is haptically perceived as a detent rotation.

Erfolgt dagegen eine Druckbetätigung des Bedienelements, was in der Figur 4 durch den Richtungspfeil einer Kraft F in senkrechter Richtung auf das Betätigungselement 1 angedeutet ist, so wird der Lagerbock 3 senkrecht zum Gehäuse 4 verschoben, wodurch der Schaltdom 14 zusammengepresst wird und auf dem Schaltungsträger einen Schaltkontakt öffnet oder schließt. Hierdurch wird ein auswertbares elektrisches Signal generiert.If, however, a pressure actuation of the operating element, which in the FIG. 4 is indicated by the directional arrow of a force F in the vertical direction on the actuating element 1, the bearing block 3 is displaced perpendicular to the housing 4, whereby the switching dome 14 is compressed and opens or closes a switching contact on the circuit carrier. As a result, an evaluable electrical signal is generated.

Durch die Verschiebung des Lagerbocks 3 verringert sich zugleich der Abstand zwischen dem freien Endabschnitt 11 des Hebels 9 und einem feststehenden Gegenstand, etwa einem Teil des Gehäuses 4 oder, wie hier dargestellt, dem Schaltungsträger 12. Das Auftreffen des Endabschnitts 11 des Hebels 9 auf den Schaltungsträger 12 bildet so einen Endanschlag für die Druckbetätigung aus.Due to the displacement of the bearing block 3, the distance between the free end portion 11 of the lever 9 and a reduced at the same time fixed object, such as a part of the housing 4 or, as shown here, the circuit substrate 12. The impact of the end portion 11 of the lever 9 on the circuit substrate 12 thus forms an end stop for the printing operation.

Wie die Figur 5 zeigt, wird beim Versuch, ein druckbetätigtes Betätigungselement 1 zusätzlich zu drehen, die nächste Erhebung der Rastkurve 15 den Rastbolzen 16 weiter gegen die Feder 10 auslenken. Hierdurch wird der Endabschnitt 11 des Hebels 9 fester gegen den Schaltungsträger 12 gepresst. Eine Verschiebung des Rastbolzens 16 ist somit nur noch mit einem erheblichen Kraftaufwand, beziehungsweise bei einem ausreichend starr ausgeführten Hebel 9 gar nicht mehr möglich, so dass die Drehbeweglichkeit des Betätigungselements 1 nun stark eingeschränkt oder sogar aufgehoben ist. Die Drehfunktion ist damit gesperrt. Die Freigabe der Drehfunktion erfolgt erst bei einem Nachlassen der Krafteinwirkung auf das Betätigungselement 1, und wird also erst mit der Beendigung der Druckbetätigung wieder möglich.As the FIG. 5 shows, when trying to rotate a pressure-actuated actuator 1 in addition, the next survey of the locking cam 15, the locking pin 16 further deflect against the spring 10. As a result, the end portion 11 of the lever 9 is pressed firmly against the circuit substrate 12. A displacement of the locking bolt 16 is thus no longer possible only with a considerable force, or in a sufficiently rigidly executed lever 9, so that the rotational mobility of the actuating element 1 is now severely limited or even repealed. The rotation function is disabled. The release of the rotational function takes place only when a decrease in the force on the actuating element 1, and is thus only possible with the completion of the printing operation again.

Die Erfindung schafft ein sowohl dreh- als auch druckbetätigbares Bedienelement bei dem eine gleichzeitige Betätigung beider Funktionen gesperrt ist. Das erfindungsgemäße Bedienelement kann vorzugsweise als Lenkradbedienelement in einem Kraftfahrzeug eingesetzt werden.The invention provides a both rotary and druckbetätigbares control in which a simultaneous operation of both functions is locked. The control element according to the invention can preferably be used as a steering wheel control element in a motor vehicle.
