Abstract
Ein elektrischer Mehrwege-Schalterbaustein mit einem Gehäuse und einem aus seiner Neutralstellung in zumindest zwei Betätigungsrichtungen verstellbaren Betätigungshebel, der sich bei Fortfall einer Betätigungskraft wieder in seine Neutralstellung zurückverlagert, ist erfindungsgemäß dadurch gekennzeichnet, dass der Betätigungshebel mit einem Oberteil des Gehäuses so starr verbunden ist, dass dessen Verstellung eine definierte elastische Verformung dieses Gehäuseoberteils bewirkt und so gemäß einer konstruktiv festgelegten Kraft-Weg-Kennlinie erfolgt, und dass in dem Gehäuse Sensorelemente einer berührungslos wirkenden Sensoreinrichtung vorhanden sind, die die Richtung und das Ausmaß einer Verstellung des Betätigungshebels erfasst und in ein Schaltsignal umwandelt.An electrical multi-way switch module with a housing and an adjustable from at least two actuation directions from its neutral position actuating lever, which relocates when discontinuing an actuating force back to its neutral position, according to the invention is characterized in that the actuating lever is so rigidly connected to an upper part of the housing, that its adjustment causes a defined elastic deformation of this housing upper part and so according to a structurally determined force-displacement curve, and that in the housing sensor elements of a non-contact sensor device are present, which detects the direction and extent of an adjustment of the actuating lever and in a Switching signal converts.
Description
Die Erfindung betrifft einen elektrischen Mehrwege-Schalterbaustein mit einem Gehäuse und einem aus seiner Neutralstellung in zumindest zwei Betätigungsrichtungen verstellbaren Betätigungshebel, der sich bei Fortfall einer Betätigungskraft wieder in seine Neutralstellung zurückverlagert.The invention relates to a multi-way electrical switch module with a housing and an adjustable from at least two actuation directions of its neutral position actuating lever, which relocated when discontinuing an operating force back to its neutral position.
Solche Mehrwege-Schalterbausteine werden etwa in Kraftfahrzeugen als universell verwendbare Komponenten zum Aufbau von mehr oder weniger komplexen Schalteranordnungen verwendet. Die Schalterbausteine sind dabei etwa vorzugsweise als Zweiwege- oder Vierwege-Schalterbausteine ausgebildet und auf einer gemeinsamen Leiterplatte montiert, die in einem eine Bedienoberfläche mit den Schalterbausteinen zugeordneten Betätigungsgriffstücken aufweisenden Gehäuse aufgenommen ist. Eine derartige Schalteranordnung unter Verwendung mehrerer Zweiwege- und Vierwege-Schalterbausteine ist z. B. aus der deutschen Patentschrift
Mehrwege-Schalterbausteine, die in derartigen Schalteranordnungen verwendet werden, müssen so beschaffen sein, dass mit ihnen ohne wesentliche Änderungen ihres grundsätzlichen Aufbaus unterschiedliche Anforderungen bezüglich der mit ihnen realisierbaren Kraft-Weg-Kennlinien erfüllt werden können.Multi-way switch components that are used in such switch assemblies must be designed so that they can be met with them without significant changes in their basic structure different requirements regarding the realizable with them force-displacement characteristics.
Die deutsche Offenlegungsschrift
Der elektrische Mehrwege-Schalterbaustein gemäß der vorliegenden Erfindung stellt eine sehr einfache und kostengünstige Möglichkeit zur sehr präzisen Realisierung von Kraft-Weg-Kennlinien insbesondere bei relativ kleinen Auslenkungen des Betätigungshebels zur Verfügung.The electrical multi-way switch module according to the present invention provides a very simple and cost-effective option for the very precise realization of force-displacement characteristics, in particular with relatively small deflections of the actuating lever.
Dies wird erfindungsgemäß dadurch erreicht, dass der Betätigungshebel mit einem Oberteil des Gehäuses so starr verbunden ist, dass dessen Verstellung eine definierte elastische Verformung dieses Gehäuseoberteils bewirkt und so gemäß einer konstruktiv festgelegten Kraft-Weg-Kennlinie erfolgt, und dass in dem Gehäuse Sensorelemente einer berührungslos wirkenden Sensoreinrichtung vorhanden sind, die die Richtung und das Ausmaß einer Verstellung des Betätigungshebels erfasst und in ein Schaltsignal umwandelt.This is inventively achieved in that the actuating lever is so rigidly connected to an upper part of the housing, that the adjustment causes a defined elastic deformation of this housing upper part and so according to a structurally determined force-displacement curve, and that in the housing sensor elements of a non-contact acting sensor device are detected, which detects the direction and the extent of an adjustment of the actuating lever and converts it into a switching signal.
Gerade in solchen Anwendungen, in denen nur sehr kleine Auslenkungen des Betätigungshebels erwünscht oder zulässig sind, und die als wesentliches Kriterium für die Auslösung eines Schaltsignals das Erreichen einer bestimmten Betätigungskraft vorsehen, kann der erfindungsgemäße elektrische Mehrwege-Schalterbaustein als quasi kraftsensitiver Schalterbaustein vorteilhaft eingesetzt werden.Especially in such applications in which only very small deflections of the actuating lever are desired or permissible, and provide as essential criterion for the triggering of a switching signal to achieve a certain operating force, the electrical multi-way switch module according to the invention can be used advantageously as a quasi-force sensitive switch module.
Eine besonders einfache und kostengünstige Ausführungsform des erfindungsgemäßen elektrischen Mehrwege-Schalterbausteins sieht vor, dass das Gehäuseoberteil mit dem Betätigungshebel als einstückiges Spritzgußteil aus einem thermoplastischen Kunststoff ausgebildet ist, wobei zur Realisierung der konstruktiv festgelegten Kraft-Weg-Kennlinie für die Schalterbetätigung die Deckelfläche des Gehäuseoberteils mit Ausnehmungen und der Betätigungshebel mit Versteifungsrippen versehen sein können.A particularly simple and inexpensive embodiment of the electrical multi-way switch module according to the invention provides that the upper housing part is formed with the operating lever as a one-piece injection molded part of a thermoplastic material, wherein the realization of the structurally determined force-displacement curve for the switch operation, the top surface of the housing top Recesses and the operating lever can be provided with stiffening ribs.
Insbesondere dann, wenn in einer übergeordneten Schalteinrichtung ohnehin eine elektrische Leiterplatte vorhanden ist, ist es vorteilhaft, ein Unterteil des Gehäuses ebenfalls durch die elektrische Leiterplatte auszubilden. Ansonsten kann das Gehäuseunterteil natürlich auch ein separates Teil ähnlich dem Gehäuseoberteil sein, das dann an seiner Außenseite Anschlüsse zur elektrischen Kontaktierung des Schalterbausteins aufweist.In particular, when an electrical circuit board is present anyway in a higher-level switching device, it is advantageous to also form a lower part of the housing through the electrical circuit board. Otherwise, the lower housing part may of course also be a separate part similar to the upper housing part, which then has on its outer side terminals for electrical contacting of the switch module.
Die die Verstellung des Betätigungshebels erfassende Sensoreinrichtung ist vorzugsweise als kapazitive Sensoreinrichtung ausgebildet, deren Sensorelemente als metallische oder metallisierte Flächen ausgeführt sind, die miteinander zur Bildung elektrischer Kondensatoren kooperieren.The sensor device detecting the adjustment of the actuating lever is preferably designed as a capacitive sensor device whose sensor elements are designed as metallic or metallized surfaces which cooperate with one another to form electrical capacitors.
In einer bevorzugten Ausführungsform eines elektrischen Vierwege-Schalterbausteins mit kapazitiver Sensoreinrichtung sind auf der Leiterplatte vier gleichgroße, voneinander elektrisch isolierte Leiterflächen angeordnet, denen in geringem Abstand gegenüberliegend und diese flächenmäßig insgesamt überdeckend eine Metallplatte zugeordnet ist, die mit einem in die Innenseite des Gehäuses hineinragenden Abschnitt des Betätigungshebels fest verbunden und in der Neutralstellung desselben parallel zu der Leiterplatte ausgerichtet ist.In a preferred embodiment of a four-way electrical switch module with capacitive sensor device four equally sized, mutually electrically insulated conductor surfaces are arranged on the printed circuit board, which at a small distance opposite and these overall area covering a metal plate is assigned, with a projecting into the inside of the housing section the actuating lever firmly connected and in the neutral position thereof is aligned parallel to the circuit board.
