An electronic sensor responds to the pushing motion or the sliding or tractive-motion. A switch rocker (15) is supported in a rotating manner. The switch rocker is operated by the switch elements.

Description

Die vorliegende Erfindung betrifft einen Schalter mit zumindest zwei Schaltelementen, wobei die Schaltelemente sowohl durch eine Drückbewegung als auch durch eine Schiebe-/Zug-Bewegung, die im Wesentlichen senkrecht zu der Drückbewegung orientiert ist, betätigbar sind.The present invention relates to a switch having at least two switching elements, wherein the switching elements are actuated both by a pushing movement and by a push / pull movement, which is oriented substantially perpendicular to the pressing movement.

Derartige Schalter mit mehr als einem Schaltelement, die jeweils verschiedene Schaltfunktionen ausführen, sind in unterschiedlichen Ausführungsformen bekannt und werden beispielsweise als Schalter für Schiebe-und Hebedächer von Kraftfahrzeugen verwendet.Such switches with more than one switching element, each performing different switching functions are known in different embodiments and are used for example as a switch for sliding and lifting roofs of motor vehicles.

Üblicherweise weisen derartige Schalter mechanische Betätigungselemente auf. Wenn nur ein einziges mechanisches Betätigungselement verwendet wird, um mehr als ein Schaltelement zu betätigen, muss der Schalter derart konstruiert sein, dass keine Überschneidung der Schaltfunktionen auftritt und keine Fehlfunktion der Schaltelemente erfolgt. Besondere Anforderungen werden an die Konstruktion eines Schalters gestellt, wenn die Schaltelemente des Schalters sowohl durch eine Drückbewegung als auch durch eine Schiebe- / Zug-Bewegung betätigbar sein sollen, wobei diese beiden Arten der Bewegung des Schalters senkrecht zueinander orientiert sind.Usually, such switches on mechanical actuators. If only a single mechanical actuator is used to actuate more than one switching element, the switch must be designed so that no overlap of the switching functions occurs and no malfunction of the switching elements takes place. Particular requirements are placed on the construction of a switch when the switching elements of the switch are to be actuated both by a pushing movement and by a push / pull movement, these two types of movement of the switch are oriented perpendicular to each other.

Bei bekannten Schaltern der vorstehend genannten Art werden üblicherweise mechanische Verriegelungselemente verwendet, welche eine Ausführung einer nicht beabsichtigten Schaltfunktion durch eine Mechanik sperren, sobald eine bestimmte Betätigungsrichtung des Schalters, beispielsweise durch eine Drück- oder eine Zieh-/Schiebebewegung, ausgewählt ist.In known switches of the aforementioned type usually mechanical locking elements are used, which block execution of an unintentional switching function by a mechanism as soon as a certain direction of actuation of the switch, for example by a pushing or a pulling / pushing movement is selected.

Derartige mechanische Verriegelungselemente sind meistens komplex aufgebaut, und daher sind Schalter, die solche rein mechanische Verriegelungselemente verwenden, fehleranfällig und aufwändig herzustellen.Such mechanical locking elements are usually complex, and therefore switches that use such purely mechanical locking elements, error-prone and expensive to produce.

Es ist daher eine Aufgabe der Erfindung, einen Schalter der eingangs genannten Art zu schaffen, der einfach aufgebaut ist und eine zuverlässige Ausführung einer gewählten Schaltfunktion ohne eine Überschneidung mit weiteren Schaltfunktionen ermöglicht.It is therefore an object of the invention to provide a switch of the type mentioned, which is simple in construction and allows reliable execution of a selected switching function without overlapping with other switching functions.

Die Aufgabe wird gelöst durch einen Schalter mit den Merkmalen des Anspruchs 1 und insbesondere dadurch, dass der Schalter mindestens einen ersten elektronischen Sensor aufweist, der auf eine Drückbewegung oder auf eine Schiebe-/Zug-Bewegung anspricht, eine dadurch gewählte Schaltfunktion zulässt und weitere Schaltfunktionen sperrt.The object is achieved by a switch with the features of claim 1 and in particular by the fact that the switch has at least one first electronic sensor which responds to a push movement or a push / pull movement, thereby permitting a selected switching function and other switching functions locks.

Da weitere Schaltfunktionen gesperrt sind, wenn der elektronische Sensor auf eine Drückbewegung oder eine Schiebe-/Zug-Bewegung anspricht, benötigt der Schalter keine komplexen mechanischen Verriegelungselemente. Die Verriegelung weiterer, unerwünschter Schaltfunktionen erfolgt stattdessen rein elektronisch. Dadurch ist der mechanische Aufbau des Schalters einfacher und der Betrieb des Schalters zuverlässiger als bei bekannten Schaltern, die mechanische Verriegelungselemente verwenden. Ferner lässt sich der Schalter aufgrund des vereinfachten Aufbaus kostengünstiger herstellen.Since other switching functions are disabled when the electronic sensor responds to a push or pull / pull motion, the switch does not require complex mechanical locking elements. The locking of other unwanted switching functions instead takes place purely electronically. As a result, the mechanical construction of the switch is simpler and the operation of the switch more reliable than in known switches that use mechanical locking elements. Furthermore, the switch can be produced more cheaply due to the simplified structure.

Der Schalter weist vorzugsweise eine Schaltwippe auf, die drehbar gelagert ist. Die mindestens zwei Schaltelemente des Schalters können mittels der Schaltwippe betätigt werden. Da die Schaltwippe zur drehbaren Lagerung nur an einem Punkt befestigt zu werden braucht, erfordert das Anbringen der Schaltwippe nur einen geringen mechanischen Aufwand. Da zwei der Schaltelemente des Schalters vorteilhafterweise auf entgegengesetzten Seiten der Schaltwippe angeordnet sind, wird eine gleichzeitige Betätigung zumindest dieser beiden Schaltelemente durch die Verwendung der Schaltwippe verhindert.The switch preferably has a switching rocker, which is rotatably mounted. The at least two switching elements of the switch can by means of Rocker be pressed. Since the rocker must be attached to the rotatable mounting only at one point, attaching the rocker requires only a small mechanical effort. Since two of the switching elements of the switch are advantageously arranged on opposite sides of the rocker switch, a simultaneous actuation of at least these two switching elements is prevented by the use of the rocker switch.

Die Schaltwippe weist vorteilhafterweise ein Betätigungselement auf, um eine Betätigung der zumindest zwei Schaltelemente durch eine Schiebe-/Zug-Bewegung zu ermöglichen, wobei die Schiebe-/Zug-Bewegung insbesondere durch eine tangential auf das Betätigungselement ausgeübte Kraft ausführbar ist. Das Betätigungselement erleichtert die Bedienung des Schalters und sorgt dafür, dass der Schalter flexibler einsetzbar ist, beispielsweise an unterschiedlichen Orten in einem Kraftfahrzeug. Eine Schiebe-/Zug-Bewegung ist für den Benutzer des Schalters mittels des Betätigungselementes unter Umständen leichter auszuführen als eine Drückbewegung, was von dem Ort abhängt, an dem der Schalter angebracht ist.The rocker switch advantageously has an actuating element in order to enable actuation of the at least two switching elements by a sliding / pulling movement, wherein the sliding / pulling movement can be carried out in particular by a force exerted tangentially on the actuating element. The actuator facilitates the operation of the switch and ensures that the switch is more flexible, for example, at different locations in a motor vehicle. A push / pull movement may be easier for the user of the switch to do by means of the actuator than a push action, depending on the location where the switch is mounted.

An dem Schalter ist vorzugsweise zumindest eine Feder angeordnet, die mit der Schaltwippe verbunden ist und diese in eine Neutralstellung drückt. Die Neutralstellung ist insbesondere dann erforderlich, wenn mittels des Schalters Schaltfunktionen ausgeführt werden sollen, die einen nur kurzzeitigen Auslösepuls erfordern. Die Neutralstellung, bei dem kein Schaltelement betätigt ist, ist in diesem Fall eine Standardstellung des Schalters.At least one spring, which is connected to the switching rocker and presses it in a neutral position, is preferably arranged on the switch. The neutral position is required in particular when switching functions are to be executed by means of the switch, which only require a short-term triggering pulse. The neutral position, in which no switching element is actuated, is in this case a standard position of the switch.

Auf der Schaltwippe ist vorteilhafterweise mindestens ein Rastelement angebracht, damit die Schaltwippe mechanisch in einer Ruhelage einrastet. Dadurch wird eine vorteilhafte Haptik für den Benutzer des Schalters geschaffen, d.h. Schaltzustände des Schalters, die durch ein Einrasten der Schaltwippe definierbar sind, können von dem Benutzer des Schalters mittels des Tastsinns wahrgenommen werden. Insbesondere umfasst das Rastelement eine auf einer Feder gelagerte Kugel, die beispielsweise in geeignete Aussparungen eines Schaltergehäuses eingreift, wodurch die Schaltwippe in einer bestimmten Position fixierbar ist.On the rocker advantageously at least one locking element is mounted so that the rocker mechanically locks in a rest position. As a result, an advantageous feel for the user of the switch is provided, ie switching states of the switch, which can be defined by a latching of the rocker switch, can be perceived by the user of the switch by means of the sense of touch. In particular, the locking element comprises a ball mounted on a spring, which engages, for example, in suitable recesses of a switch housing, whereby the switching rocker can be fixed in a certain position.

Der mindestens eine Sensor des Schalters ist bevorzugt auf der Schaltwippe angeordnet. Durch eine Berührung der Schaltwippe an einer bestimmten Stelle kann der Benutzer des Schalters somit eine bestimmte Schaltfunktion auswählen. Der Sensor bewirkt ferner, dass weitere, nicht erwünschte Schaltfunktionen gesperrt werden.The at least one sensor of the switch is preferably arranged on the switching rocker. By touching the rocker switch at a certain point, the user of the switch can thus select a specific switching function. The sensor also causes further unwanted switching functions to be disabled.

Vorteilhafterweise ist der mindestens eine Sensor des Schalters an dem Betätigungselement der Schaltwippe angeordnet, mittels dessen der Schalter durch eine Schiebe-/Zug-Bewegung betätigbar ist. Dabei sind insbesondere zwei alternative Ausführungsformen möglich, die im Folgenden beschrieben sind.Advantageously, the at least one sensor of the switch is arranged on the actuating element of the switching rocker, by means of which the switch can be actuated by a push / pull movement. In particular, two alternative embodiments are possible, which are described below.

Gemäß einer Ausführungsform ist der an dem Betätigungselement angeordnete Sensor ausgebildet, um auf die Richtung einer Kraft selektiv anzusprechen, die auf das Betätigungselement ausgeübt wird. Mit anderen Worten kann der Sensor zwischen zwei Richtungen unterscheiden, in die das Betätigungselement der Schaltwippe bewegt wird. Dazu kann der Sensor beispielsweise sensitive Flächen auf entgegengesetzten Seiten des Betätigungselements aufweisen, durch die der Sensor ermitteln kann, welche Seite des Betätigungselements durch den Benutzer des Schalters berührt wird. Wenn der an dem Betätigungselement angeordnete Sensor auf die Richtung der ausgeübten Kraft selektiv anspricht, kann das Betätigungselement in einer einfachen Weise kostengünstig aufgebaut werden, da nur ein Sensor an dem Betätigungselement der Schaltwippe angebracht werden muss.In one embodiment, the sensor disposed on the actuator is configured to selectively respond to the direction of a force applied to the actuator. In other words, the sensor can distinguish between two directions in which the actuating element of the switching rocker is moved. For this purpose, the sensor can have, for example, sensitive surfaces on opposite sides of the actuating element, by means of which the sensor can determine which side of the actuating element is touched by the user of the switch. When the sensor disposed on the actuator selectively responds to the direction of the applied force, the actuator may be constructed inexpensively in a simple manner, since only one sensor must be attached to the actuator of the rocker switch.

Alternativ können zwei Sensoren verwendet werden, die beispielsweise auf entgegengesetzten Seiten des Betätigungselements angebracht sind. Dabei spricht der erste Sensor auf eine Richtung einer auf das Betätigungselement ausgeübten Kraft an, und der zweite Sensor spricht auf eine Kraft an, die auf das Betätigungselement in entgegengesetzter Richtung ausgeübt wird. Werden zwei Sensoren an dem Betätigungselement der Schaltwippe angeordnet, können einfachere und kostengünstigere Sensoren als bei der Ausführungsform mit nur einem Sensor verwendet werden.Alternatively, two sensors may be used, for example mounted on opposite sides of the actuator. In this case, the first sensor is responsive to a direction of a force applied to the actuator, and the second sensor is responsive to a force applied to the actuator in the opposite direction. If two sensors are arranged on the actuating element of the switching rocker, simpler and less expensive sensors than in the embodiment with only one sensor can be used.

Der Schalter weist vorzugsweise zumindest einen weiteren Sensor auf, wobei der erste Sensor auf die Drückbewegung und der weitere Sensor auf die Schiebe-/Zug-Bewegung anspricht. Dadurch wird der Drückbewegung und der Schiebe-/Zug-Bewegung, die im Wesentlichen senkrecht zueinander orientiert sind und daher zwei unterschiedlichen Betätigungsweisen des Schalters entsprechen, jeweils ein eigener Sensor zugeordnet, wodurch die Zuverlässigkeit des Schalters verbessert wird.The switch preferably has at least one further sensor, wherein the first sensor responds to the push movement and the further sensor to the push / pull movement. Thereby, the push movement and the push / pull movement, which are oriented substantially perpendicular to each other and therefore correspond to two different operations of the switch, each assigned a separate sensor, whereby the reliability of the switch is improved.

Vorteilhafterweise ist darüber hinaus jedem Schaltelement jeweils ein eigener Sensor zugeordnet, der auf eine Drückbewegung auf das jeweilige Schaltelement anspricht. Dadurch kann die Betriebssicherheit des Schalters weiter erhöht werden.Advantageously, moreover, each switching element is assigned a separate sensor, which responds to a pressing movement to the respective switching element. As a result, the reliability of the switch can be further increased.

Die Sensoren des Schalters können bevorzugt als kapazitive Sensoren ausgebildet sein. Diese Art der Sensoren ist besonders kostengünstig, insbesondere im Vergleich zu komplexen Verriegelungsmechanismen bekannter Schalter, die mehr als eine Schaltfunktion ausführen.The sensors of the switch can preferably be designed as capacitive sensors. This type of sensors is particularly cost effective, especially in comparison to complex locking mechanisms of known switches that perform more than one switching function.

Der Schalter umfasst bevorzugt eine Steuereinheit, die mit den Sensoren des Schalters verbunden ist und ausgebildet ist, um Signale der Sensoren auszuwerten. Dabei erfasst die Steuereinheit, ob ein Sensor auf eine Drückbewegung oder auf eine Schiebe-/Zug-Bewegung anspricht, und aktiviert ein Schaltelement, das diesem Sensor zugeordnet ist, wobei weitere Schaltelemente deaktiviert bzw. deren Schaltfunktionen gesperrt werden. Das Deaktivieren bzw. Sperren von unerwünschten Schaltfunktionen wird somit rein elektronisch ausgeführt, indem die Sensoren mit der Steuereinheit zusammenwirken. Zum Sperren bzw. Verriegeln unerwünschter Schaltfunktionen sind somit keine mechanischen Verriegelungselemente erforderlich.The switch preferably comprises a control unit, which is connected to the sensors of the switch and is designed to evaluate signals from the sensors. In this case, the control unit detects whether a sensor responds to a push movement or a push / pull movement, and activates a switching element which is assigned to this sensor, wherein further switching elements are deactivated or their switching functions are disabled. The deactivation or blocking of unwanted switching functions is thus carried out purely electronically by the sensors interacting with the control unit. For locking or locking unwanted switching functions thus no mechanical locking elements are required.

Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Further preferred embodiments of the invention are described in the subclaims.

Fig. 1 zeigt einen erfindungsgemäßen Schalter 11 mit zwei Schaltelementen 13a und 13b sowie einer Schaltwippe 15. Die Schaltwippe 15 ist an einem Drehpunkt 17 drehbar gelagert und weist ein Betätigungselement 19 auf. Auf der Schaltwippe 15 sind mehrere Sensoren 21 angeordnet. Die Sensoren 21a und 21b befinden sich oberhalb der Schaltelemente 13a bzw. 13b und sprechen jeweils auf eine Drückbewegung an, die jeweils durch Pfeile 23a bzw. 23b dargestellt ist. Der Sensor 21c ist an dem Betätigungselement 19 angebracht oder in dieses integriert und spricht auf eine Schiebe-/Zug-Bewegung an, die durch einen Pfeil 25 dargestellt ist. Fig. 1 shows a switch 11 according to the invention with two switching elements 13a and 13b and a rocker switch 15. The rocker switch 15 is rotatably mounted at a pivot point 17 and has an actuating element 19. On the rocker switch 15 a plurality of sensors 21 are arranged. The sensors 21a and 21b are located above the switching elements 13a and 13b, respectively, and respond to a pushing movement, respectively is shown by arrows 23a and 23b. The sensor 21c is mounted on or integrated with the actuator 19 and is responsive to a push / pull movement represented by an arrow 25.

Der Schalter 11 weist ferner zwei Federn 27 auf, die an der Schaltwippe 15 und beispielsweise an einer Gehäusewand 29 des Schalters befestigt sind. Die Federn 27 drücken die Schaltwippe 15 in eine Neutralstellung, bei der keines der Schaltelemente 13a bzw. 13b betätigt ist. Die Neutralstellung wird somit mittels der Federn 27 als Standardstellung des Schalters definiert, die automatisch eingestellt wird, sobald keine Kraft auf den Schalter wirkt. Dies ist besonders vorteilhaft, wenn eine nur kurzzeitige Betätigung der Schaltelemente 13a bzw. 13b erwünscht bzw. gefordert ist.The switch 11 also has two springs 27 which are attached to the rocker switch 15 and, for example, to a housing wall 29 of the switch. The springs 27 press the rocker switch 15 in a neutral position, in which none of the switching elements 13a and 13b is actuated. The neutral position is thus defined by means of the springs 27 as the default position of the switch, which is set automatically when no force acts on the switch. This is particularly advantageous when only a short-term actuation of the switching elements 13a and 13b is desired or required.

Sobald einer der Sensoren 21 a - c auf eine Drückbewegung oder eine Schiebe-/Zug-Bewegung anspricht, wird ein Sensorsignal von dem entsprechenden Sensor erzeugt und an eine Steuereinheit 30 gesendet. Die Steuereinheit 30 ordnet das Sensorsignal einem der Schaltelemente 13a oder 13b zu, aktiviert dieses und deaktiviert weitere Schaltelemente.As soon as one of the sensors 21 a - c responds to a pushing movement or a sliding / pulling movement, a sensor signal is generated by the corresponding sensor and sent to a control unit 30. The control unit 30 assigns the sensor signal to one of the switching elements 13a or 13b, activates it and deactivates further switching elements.

Wenn beispielsweise eine Drückbewegung, die durch den Pfeil 23a dargestellt ist, auf die Schaltwippe 15 im Bereich des Sensors 21a ausgeübt wird, aktiviert die Steuereinheit 30 das Schaltelement 13a und deaktiviert das Schaltelement 13b. Wird alternativ eine Schiebe-/Zug-Bewegung auf das Betätigungselement 19 der Schaltwippe 15 ausgeübt, so ermittelt der Sensor 21c, in welche Richtung die Schiebe-/Zug-Bewegung erfolgt und ordnet diese Bewegung dem entsprechenden Schaltelement zu, beispielsweise dem Schaltelement 13b, und aktiviert dieses, während das weitere Schaltelement 13a deaktiviert wird.If, for example, a pushing movement, which is represented by the arrow 23a, is exerted on the switching rocker 15 in the region of the sensor 21a, the control unit 30 activates the switching element 13a and deactivates the switching element 13b. Alternatively, if a sliding / pulling movement is exerted on the actuating element 19 of the rocker switch 15, the sensor 21c determines in which direction the sliding / pulling movement takes place and assigns this movement to the corresponding switching element, for example the switching element 13b, and activates this, while the further switching element 13a is deactivated.

Fig. 2 zeigt eine besondere Ausführungsform des Schalters von Fig. 1, wobei nur die linke Seite der Schaltwippe 15 beispielhaft dargestellt ist, die an dem Drehpunkt 17 gelagert ist. Die Schaltwippe 15 weist an ihrer linken Seite ein Rastelement 31 auf, das eine Feder 33 und eine Kugel 35 aufweist. Bei einer Bewegung der Schaltwippe 15 kann die Kugel 35 in Aussparungen 37 einrasten, die beispielsweise in einem Gehäuseabschnitt 39 des Schalters vorgesehen sind. Sobald die Schaltwippe eine vorbestimmte Position erreicht, kann sie somit mittels der Kugel 35 in dieser Position fixiert werden. Dadurch können definierte Schaltzustände und eine Haptik definiert werden, d.h. der Benutzer des Schalters 11 kann die Schaltzustände mit seinem Tastsinn erfassen. Insbesondere sind die Aussparungen 37 unterschiedlich tief ausgebildet, damit der Benutzer des Schalters 11 mittels des Tastsinns zwischen verschiedenen Schaltzuständen unterscheiden kann. Fig. 2 shows a particular embodiment of the switch of Fig. 1 , wherein only the left side of the rocker switch 15 is shown by way of example, which is mounted at the pivot point 17. The switching rocker 15 has on its left side a locking element 31, which has a spring 33 and a ball 35. Upon movement of the rocker switch 15, the ball 35 can engage in recesses 37, which are provided for example in a housing portion 39 of the switch. Once the rocker switch reaches a predetermined position, it can thus be fixed by means of the ball 35 in this position. As a result, defined switching states and a haptic can be defined, ie the user of the switch 11 can detect the switching states with his sense of touch. In particular, the recesses 37 are formed differently deep, so that the user of the switch 11 can distinguish by means of the sense of touch between different switching states.
