Description
Die Erfindung betrifft einen Lenkradschalter.The The invention relates to a steering wheel switch.
Es sind Lenkradschalter bekannt, die durch einen Kraftsensor oder ein Kontaktelement mit kinematischer Komponente gekennzeichnet sind. Bei diesen Lenkradschaltern wird also eine Kraft, die über einen Weg aufgebracht wird, in ein elektrisches Signal umgesetzt. Deshalb müssen Teile des Lenkrades beweglich gestaltet werden, um diese Kraft-Weg-Umsetzung zu gewährleisten. Diese Schalter sind als gesonderte Komponente im Lenkrad angeordnet und bestehen vereinfacht aus Sub-Komponenten, wie einem Taster, einem kinematischen Teil, einer Blende, einem Kraftsensor oder Kontaktelement, einer Elektronik und einem Gehäuse. Der Schalter funktioniert als autarke Komponente unabhängig von den übrigen Komponenten des Lenkrades.It Steering wheel switches are known by a force sensor or a Contact element with kinematic component are marked. In these steering wheel switches so a force that is over a Path is applied, converted into an electrical signal. Therefore have to Parts of the steering wheel are made movable to implement this force-displacement to ensure. These switches are arranged as a separate component in the steering wheel and consist of simplified sub-components, such as a button, a kinematic part, a diaphragm, a force sensor or contact element, an electronics and a housing. The switch works as a stand alone component regardless of the rest Components of the steering wheel.
Der Nachteil dieser Lenkradschalter besteht darin, dass mehrere Werkzeuge für den Bau der Sub-Komponenten Schaltergehäuse, Schalterblende und Schaltertasten erforderlich sind. Der Lenkradschalter wird in der Praxis als gesonderte Baugruppe von einem Zulieferer entwickelt und gefertigt. Eine bessere Integration des Lenkradschalters in das Lenkrad ist wegen dieser modularen Bauweise des Lenkradschalters kaum möglich.Of the Disadvantage of this steering wheel switch is that several tools for the Construction of sub-component switch housing, switch panel and switch buttons required are. The steering wheel switch is in practice as a separate Assembly developed and manufactured by a supplier. A better Integration of the steering wheel switch in the steering wheel is because of this modular design of the steering wheel switch hardly possible.

Der Erfindung liegt die Aufgabe zugrunde, den Lenkradschalter so zu vereinfachen, dass er integrierte Komponente des Lenkrades werden kann.Of the Invention is based on the object, the steering wheel switch so simplify that he will be integrated component of the steering wheel can.
Erfindungsgemäß wird das gemäß den Merkmalen des Anspruchs 1 erreicht.According to the invention according to the characteristics of claim 1 achieved.
Bei einem Lenkradschalter mit mindestens einem piezoelektrischen Kraftsensor in Form einer flexiblen piezoelektrischen Folie, die unter einer Lenkradverkleidung und/oder einer Airbagmodul-Abdeckung angeordnet ist, von denen mindestens ein Abschnitt als Betätigungselement zur Beaufschlagung des jeweiligen Sensors mit einer Kraftkomponente dient, ist erfindungsgemäß vorgesehen, dass die flexible Folie in mindestens einen druckempfindlichen und mindestens einen druckunempflndlichen Bereich unterteilt ist. Dabei ist es zweckmäßig, dass jeder druckunempfindliche Bereich der flexiblen Folie von der Unterseite durch je eine Komponente des Lenkrades und/oder des Airbagmoduls abgestützt ist. Damit wird gewährleistet, dass sich nur die druckempfindlichen Bereiche bewegen können. Diese Bereiche können damit von der Elektronik ausgewertet werden. In einer zweckmäßigen Ausgestaltung ist vorgesehen, dass die druckunempfindlichen Bereiche der flexiblen Folie auf dem Lenkradskelett aufliegen und dass die Folie unter einer Lenkrad-Speichenblende, die einen Abschnitt der Lenkradverkleidung darstellt, befestigt ist. Damit können die Lenkrad-Speichenblende und die Folie über die gesamte gemeinsame Fläche eine Verbindung eingehen.at a steering wheel switch with at least one piezoelectric force sensor in the form of a flexible piezoelectric film under a steering wheel cover and / or an airbag module cover is arranged, of which at least a section as an actuator for acting on the respective sensor with a force component serves, is provided according to the invention, that the flexible film in at least one pressure-sensitive and is divided at least one pressure-insensitive area. there it is appropriate that everyone pressure-resistant area of the flexible film from the bottom by a respective component of the steering wheel and / or the airbag module is supported. This will ensure that only the pressure-sensitive areas can move. These Areas can so that they are evaluated by the electronics. In an expedient embodiment is provided that the pressure-insensitive areas of the flexible Slide film on the steering wheel skeleton and that the film is under a steering wheel spoke panel that covers a portion of the steering wheel fairing represents, is attached. This allows the steering wheel-spoke aperture and the slide over the entire common area make a connection.
Die druckunempfindlichen Bereiche der flexiblen Folie liegen bei einer bevorzugten Ausführungsform auf Auflageabschnitten, die im Abstand zueinander angeordnet sind.The pressure-insensitive areas of the flexible film are at a preferred embodiment on support sections, which are arranged at a distance from each other.
Die Folie ist vorzugsweise mittels Kleber oder Thermolack auf ihrer gesamten Fläche mit der Lenkradspeichenblende verbunden.The Foil is preferably by means of adhesive or thermoresist on her entire area connected to the steering wheel spoke panel.
Ein besonderer Vorteil dieser Anordnung besteht darin, dass Schalter Sub-Komponenten eines herkömmlichen Schalters wie Tasten Gehäuse und kinematische Komponenten durch bestehende Lenkradkomponenten wie z.B. Skelett, Zierblenden und sonstige Lenkradoberflächen ersetzt worden sind.One particular advantage of this arrangement is that switch Sub-components of a conventional Switches like buttons housing and kinematic components through existing steering wheel components such as. Skeleton, trim and other steering wheel surfaces replaced have been.
Da bei diesem Lenkradschalter keine für den Menschen messbare Kraft-Weg-Kennlinie existiert, ist es zweckmäßig, dass zur Betätigung eines Schaltvorganges eine haptische und/oder akustische und/oder optische Rückmeldung vorgesehen ist.There in this steering wheel switch no man-measurable force-displacement curve exists, it is appropriate that for operation a switching process a haptic and / or acoustic and / or visual feedback is provided.
Mindestens ein Sensor ist über eine elektrische Leitung mit einer Elektronik verbunden, die die Schaltvorgänge auslöst.At least a sensor is over an electrical line connected to an electronics that triggers the switching operations.
