Description
Die Erfindung betrifft ein druck- und drehbetätigbares Bedienelement für ein Kraftfahrzeug, insbesondere Lenkradbedienelement, mit einem scheiben- oder walzenförmigen, auf einem Lagerbock drehbar gelagerten Eingabeelement, mit einem Drehsensor zur Erfassung einer Drehbetätigung des Eingabeelements, mit einem Schaltungsträger und mit Schaltkontaktelementen, die zusammen wenigstens ein Schaltelement ausbilden, welches durch eine Druckbetätigung des Eingabeelements betätigbar ist, wobei der Drehsensor vollständig am Lagerbock angeordnet ist und der Lagerbock mit den Schaltkontaktelementen verbunden ist.The invention relates to a pressure and drehbetätigbares operating element for a motor vehicle, in particular steering wheel control element, with a disk-shaped or cylindrical, rotatably mounted on a bearing input element, with a rotation sensor for detecting a rotary actuation of the input element, with a circuit carrier and with switching contact elements, which together at least form a switching element which can be actuated by a pressure actuation of the input element, wherein the rotation sensor is arranged completely on the bearing block and the bearing block is connected to the switching contact elements.
Ein derartiges druck- und drehbetätigbares Bedienelement ist aus der europäischen Patentanmeldung
Die deutsche Offenlegungsschrift
Aus der
Nachteilig an dieser vorbekannten Bedienvorrichtung ist, dass das Eingabeelement, der Lagerbock sowie die starre Leiterplatte gegeneinander unbeweglich miteinander verbunden sind. Dies ist hier erforderlich, um zur Ausbildung des Drehsensors das Geberrad und den optoelektronischen Sensor exakt zueinander zu positionieren. Hierdurch entsteht aber eine relativ großbauende Anordnung. Ebenfalls nachteilig ist, dass zur Ausbildung der Druckschaltfunktion diese relativ unhandliche Anordnung noch gegenüber einem Gehäuseteil verschwenkbar angeordnet sein muss.A disadvantage of this known operating device that the input element, the bearing block and the rigid circuit board are immovably connected to each other. This is necessary here in order to position the encoder wheel and the optoelectronic sensor exactly to one another for the purpose of forming the rotary sensor. However, this creates a relatively bulky arrangement. Another disadvantage is that in order to form the pressure switching function, this relatively unwieldy arrangement still has to be arranged pivotably relative to a housing part.
Es stellte sich die Aufgabe, ein Bedienelement zu schaffen, das sich durch einen einfacheren und kompakteren Aufbau auszeichnet.It set itself the task of creating a control that is characterized by a simpler and more compact structure.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Schaltkontaktelemente durch eine Domschaltmatte ausgebildet sind, dass der Drehsensor ein Schleifringkontaktschalter ist, der über eine Leiterfolie elektrisch kontaktiert ist, und dass die den Schleifring des Schleifringkontaktschalters kontaktierenden Kontaktflächen auf einem Abschnitt der Leiterfolie angeordnet sind.This object is achieved in that the switching contact elements are formed by a Domschaltmatte that the rotation sensor is a slip ring contact switch, which is electrically contacted via a conductor foil, and that the slip ring of the slip ring contact switch contacting contact surfaces are arranged on a portion of the conductor foil.
Erfindungsgemäß vorgesehen ist, dass der Schaltungsträger durch eine flexible Leiterfolie gebildet ist, die zugleich einen Bestandteil des Drehsensors ausbildet und darüber hinaus zur elektrischen Kontaktierung des Drehsensors und wenigstens eines Schaltkontakts einer Druckschaltfunktion vorgesehen ist.According to the invention, the circuit carrier is formed by a flexible conductor foil, which at the same time forms a component of the rotation sensor and, moreover, is provided for electrically contacting the rotation sensor and at least one switching contact of a pressure switching function.
Der am Lagerbock angeordnete Drehsensor ist als ein Schleifringkontaktschalter ausgebildet, der dadurch besonders kompakt zwischen dem Eingabeelement und einer Wandfläche des Lagerbocks angeordnet ist.The arranged on the bearing block rotation sensor is designed as a slip ring contact switch, which is thereby arranged particularly compact between the input element and a wall surface of the bearing block.
Die Kontaktflächen des Schleifringkontaktschalters sind auf einem Abschnitt einer Leiterfolie angeordnet. Die Leiterfolie dient so vorteilhaft zugleich zur elektrischen Anbindung des Drehsensors.The contact surfaces of the slip ring contact switch are arranged on a portion of a conductor foil. The conductor foil serves so advantageous at the same time for the electrical connection of the rotary sensor.
Ein druck- und drehbetätigbares Bedienelement, welches einen Schleifringkontaktschalter aufweist, zeigt bereits die Druckschrift
Durch die vollständige Anordnung des Drehsensors am Lagerbock ist die Drehbetätigungsfunktion durch eine vormontierbare Baueinheit realisiert, die relativ kompakt herstellbar ist. Besonders vorteilhaft ist, dass die Drehbetätigungsfunktion vor einer weiteren Montage dieser Baueinheit auf eine fehlerfreie Funktion hin prüfbar ist.Due to the complete arrangement of the rotary sensor on the bearing block, the rotary actuation function is realized by a pre-assembled unit, which is relatively compact to produce. It is particularly advantageous that the rotary actuation function can be tested for a faultless function before a further assembly of this structural unit.
Die vormontierte Baueinheit bildet des weiteren die Betätigungseinrichtung zur Auslösung wenigstens einer Druckschaltfunktion. Hierzu ist der Lagerbock bei dem fertig montierten Bedienelement mit der Domschaltmatte verbunden.The preassembled unit further forms the actuating device for triggering at least one pressure switching function. For this purpose, the bearing block is connected to the ready-mounted control with the Domschaltmatte.
In einer ersten Ausführungsform der Erfindung kann der Lagerbock hierbei mit einem oder mehreren Schaltdomen der Domschaltmatte verbunden sein und dadurch bei einer Druckbetätigung des Eingabeelements eine oder mehrere Schaltfunktionen auslösen.In a first embodiment of the invention, the bearing block can in this case be connected to one or more switching domes of the Domschaltmatte and thereby at a pressure actuation of the Input element trigger one or more switching functions.
Eine derartige Ausführung ist besonders dann vorteilhaft, wenn die von der Domschaltmatte betätigten Schaltkontakte auf einer relativ großflächigen Leiterplatte angeordnet sind. Der Lagerbock steht so in keiner direkten mechanischen Verbindung mit dem Schaltungsträger, so dass bei einer Druckbetätigung lediglich ein oder mehrere Schaltdome bewegt werden. Hierdurch bilden die für Dreh- und Druckbetätigungen erforderlichen beweglichen Teile insgesamt eine sehr kompakte Anordnung, so dass das erfindungsgemäße Bedienelement sehr gut handhabbar ist.Such a design is particularly advantageous if the actuated by the Domschaltmatte switching contacts are arranged on a relatively large printed circuit board. The bearing block is thus in no direct mechanical connection with the circuit carrier, so that only one or more switching dome are moved in a pressure actuation. As a result, the moving parts required for rotary and pressure actuations form a very compact arrangement overall, so that the operating element according to the invention is very easy to handle.
Eine alternative Ausführungsform des erfindungsgemäßen Bedienelements ist vorteilhaft verwendbar, wenn ein relativ kleinflächiger Schaltungsträger vorgesehen ist, der insbesondere nur die Schaltkontakte für wenige Schaltdome der Domschaltmatte aufweisen soll.An alternative embodiment of the operating element according to the invention can be used advantageously if a relatively small-area circuit carrier is provided, which in particular should have only the switching contacts for a few switching domes of the Domschaltmatte.
In diesem Fall kann der Lagerbock mit der Grundfläche der Domschaltmatte verbunden sein, wobei der relativ kleinflächige Schaltungsträger, der die Schaltkontakte zu den Schaltdomen auf der Domschaltmatte trägt, zwischen der Domschaltmatte und dem Lagerbock gehaltert ist.In this case, the bearing block may be connected to the base of Domschaltmatte, wherein the relatively small-area circuit carrier, which carries the switching contacts to the switching domes on the Domschaltmatte, between the Domschaltmatte and the bearing block is supported.
