Description
Die vorliegende Erfindung betrifft eine Sensoreinrichtung zur Erfassung der Benetzung einer Scheibe gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a sensor device for detection the wetting of a pane according to the generic term of claim 1.
Eine
derartige Vorrichtung ist aus der
Diese Anordnung ist jedoch mit Nachteilen behaftet. Zumeist verfügen derartige Sensoreinrichtungen über ein quaderförmiges Gehäuse mit einer rechteckförmigen Grundfläche. Insbesondere durch die dreieckförmige Anordnung der Sende- und Empfangseinheiten bleibt, bereits geometrisch bedingt, ein großer Bereich der Grundfläche ungenutzt. Diese Feststellung trifft auch für die Anordnung in den Eckpunkten eines Parallelogramms zu. Insgesamt scheint auch die hier vorgeschlagene Anordnung nicht zu einer optimalen Ausnutzung der Grundfläche der Sensoreinrichtung zu führen.This However, the arrangement has disadvantages. Mostly have such Sensor devices over a cuboid casing with a rectangular shape Floor space. Especially due to the triangular shape The arrangement of the transmitting and receiving units remains geometrical conditionally, a big one Area of the base unused. This also applies to the arrangement in the corner points a parallelogram. Overall, the one proposed here also seems Arrangement does not lead to an optimal use of the base of the To lead sensor device.
Hier setzt die vorliegende Erfindung an und macht es sich zur Aufgabe eine Sensoreinrichtung bereitzustellen, welche die zur Verfügung stehende Grundfläche besser ausnutzt und somit eine geringere Abmessung bei gleichbleibender Sensorqualität aufweist.Here applies the present invention and makes it its task to provide a sensor device which improves the available base area exploits and thus a smaller dimension with the same Has sensor quality.
Erfindungsgemäß wird diese Aufgabe durch eine Sensoreinrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dadurch, dass die zweite Einkopplungsoptik zwischen der ersten Einkopplungsoptik und der ersten Auskopplungsoptik angeordnet ist, wird eine Sensoreinrichtung bereitgestellt, welche die zur Verfügung stehende Grundfläche des Gehäuses wesentlich besser ausnutzt, da die einzelnen Messstrecken ineinander verschachtelt sind. Dementsprechend kann bei gleicher Sensorqualität ein kleineres Gehäuse gewählt werden, oder aber die Sensorqualität bei gleichbleibendem Gehäuse gesteigert werden.According to the invention Task by a sensor device with the characteristic features of claim 1 solved. Characterized in that the second coupling optics between the first coupling optics and the first coupling optics is arranged, a sensor device provided which is the available area of the housing makes much better use of it, since the individual measurement sections interlock are nested. Accordingly, a smaller one can be used with the same sensor quality casing chosen be, or the sensor quality increased with the same housing become.
In einer weiteren vorteilhaften Ausführungsform der vorliegenden Erfindung kann vorgesehen sein, dass die erste Auskopplungsoptik zwischen der zweiten Einkopplungsoptik und der zweiten Auskopplungsoptik angeordnet ist. Durch diese Maßnahme kann ebenfalls eine weitere Leistungssteigerung der Sensoreinrichtung durch Verschachtelung der Messstrecken erreicht werden.In a further advantageous embodiment of the present The invention can provide that the first coupling optics between the second coupling optics and the second coupling optics is arranged. By this measure can also further increase the performance of the sensor device can be achieved by nesting the measuring sections.
Vorteilhafterweise kann weiterhin vorgesehen sein, dass die Einkopplungsoptiken und die Auskopplungsoptiken in einer Reihe entlang einer Längsachse des Gehäuses angeordnet sind. Diese Bauform bietet sich für die Anordnung der Einkopplungs- bzw. Auskopplungsoptiken an, da hierdurch der Bauraum vorteilhafterweise ausgenutzt wird.advantageously, can also be provided that the coupling optics and the decoupling optics in a row along a longitudinal axis of the housing are arranged. This design is suitable for the arrangement of the coupling or Decoupling optics, since this advantageously allows the installation space is exploited.
Auch kann weiterhin vorteilhafterweise vorgesehen sein, dass die erste Einkopplungsoptik und die erste Auskopplungsoptik mit einem seitlichen Versatz zu der zweiten Einkopplungsoptik und der zweiten Auskopplungsoptik entlang einer Längsachse des Gehäuses angeordnet sind. Hierdurch werden die Messstrecken voneinander getrennt, so dass beispielsweise keine Interferenzmuster entstehen können.Also can also advantageously be provided that the first Coupling optics and the first coupling optics with a lateral offset to the second coupling optics and the second coupling optics along a longitudinal axis of the housing are arranged. This separates the measuring sections from one another, so that, for example, no interference patterns can arise.
Weiterhin kann vorteilhafterweise vorgesehen sein, dass mindestens zwei weitere Messstrecken neben den Messstrecken angeordnet sind. Die ineinandergeschachtelten Messstrecken lassen sich nahezu beliebig nebeneinander oder hintereinander aufbauen, je nachdem wie viele Messstrecken für die Sensoreinrichtung benötigt werden. Hierdurch wird die Gesamtauflösung der Sensoreinrichtung bei kleinem Bauraum des Gehäuses erhöht.Farther can advantageously be provided that at least two more Measuring sections are arranged next to the measuring sections. The nested Measuring sections can be set up side by side or one behind the other, depending on how many measuring sections are required for the sensor device. This will make the overall resolution the sensor device increases in a small space of the housing.
Um einer möglichen gegenseitigen Beeinflussung der Messstrecken entgegenzuwirken kann vorteilhafterweise vorgesehen sein, dass die weiteren Messstrecken einen Versatz in Richtung der Längsachse durch die Messstrecken aufweisen.Around one possible counteracting mutual influence of the measurement sections can advantageously it should be provided that the further measuring sections have an offset in Direction of the longitudinal axis through the measurement sections.
Zur Vereinfachung der Montage und zur Rationalisierung des Herstellungsprozesses kann vorteilhafterweise vorgesehen sein, dass die Einkopplungsoptiken und Auskopplungsoptiken einstückig ausgeführt sind.to Simplification of assembly and rationalization of the manufacturing process can advantageously be provided that the coupling optics and decoupling optics are made in one piece.
Eine weitere vorteilhafte Ausgestaltung der vorliegenden Erfindung besteht darin, dass die Einkopplungsoptiken und die Auskopplungsoptiken und das Gehäuse einstückig durch ein Mehrkomponentenspritzgießverfahren hergestellt worden sind. Auch durch diese Maßnahme wird eine rationelle Bereitstellung einer erfindungsgemäßen Sensoreinrichtung ermöglicht.A there is a further advantageous embodiment of the present invention in that the coupling optics and the coupling optics and the housing one piece produced by a multi-component injection molding process are. Also through this measure a rational provision of a sensor device according to the invention is made possible.
Zur blasenfreien Verbindung zwischen den Kopplungsoptiken und der Scheibe kann vorteilhafterweise vorgesehen sein, dass das Gehäuse an der Scheibe befestigt ist, wobei zwischen der Scheibe und den Einkopplungsoptiken bzw. den Auskopplungsoptiken ein Kopplungspad vorgesehen ist.to bubble-free connection between the coupling optics and the disk can advantageously be provided that the housing on the disc is attached, being between the disc and the coupling optics or the coupling optics a coupling pad is provided.
In einer weiteren vorteilhaften Weiterbildung der vorliegenden erfindungsgemäßen Sensoreinrichtung kann vorgesehen sein, dass die Sensoreinrichtung weiterhin über einen Lichtsensor und/oder einen Sonnensensor und/oder eine Kamera verfügt. Durch diese Ausgestaltung kann der Funktionsbereich der Sensoreinrichtung wesentlich erweitert werden. Beispielsweise ist eine erfindungsgemäße Sensoreinrichtung klein genug, um in den Spiegelfuß eines Innenspiegels des Fahrzeugs integriert zu werden.In a further advantageous development of the present sensor device according to the invention it can be provided that the sensor device continues to have a Light sensor and / or a sun sensor and / or a camera has. Through this Design, the functional area of the sensor device can be essential be expanded. For example, is a sensor device according to the invention small enough to be in the mirror base of an inside mirror of the vehicle to be integrated.
