Abstract
Description
Die Erfindung betrifft eine Sensoranordnung für ein Kraftfahrzeug, mit einem an einer Fahrzeugscheibe befestigbaren Halterahmen, mit einem an den Halterahmen anfügbaren Sensorgehäuse, und mit einer Flachformfeder, die im montierten Zustand mit dem Halterahmen verbunden ist und das Sensorgehäuse federnd an die Fahrzeugscheibe anpresst.The The invention relates to a sensor arrangement for a motor vehicle, with an attachable to a vehicle window holding frame, with a sensor housing attachable to the support frame, and with a flat spring, which in the assembled state with the Holding frame is connected and the sensor housing resilient presses against the vehicle window.
Eine
derartige Sensoranordnung ist in der deutschen Offenlegungsschrift
Da die Blattfeder eine hohe Kraft zum Anpressen des Sensorgehäuses an die Fahrzeugscheibe erzeugt, ist auch die erforderliche Montagekraft zum Verbinden der Blattfeder mit dem Befestigungsring relativ hoch. Hierdurch ist die Montage des Sensorgehäuses an die Fahrzeugscheibe unkomfortabel und relativ aufwendig.There the leaf spring a high force for pressing the sensor housing generated to the vehicle window, the required mounting force for Connecting the leaf spring with the mounting ring relatively high. As a result, the mounting of the sensor housing to the vehicle window uncomfortable and relatively expensive.
Eine
weitere Sensoranordnung gemäß des Oberbegriffs
ist in der nicht vorveröffentlichten deutschen Patentanmeldung
Die Montage des Spannbügels erfolgt hier in zwei Montageschritten und zwar ersten durch Einklipsen des Spannbügels am Halterahmen und zweitens durch das Verschieben des Spannbügels gegen das Sensorgehäuse. Das Einklipsen des Spannbügels am Halterahmen kann mit einem geringen Kraftaufwand erfolgen, der im wesentlichen durch die erforderliche Kraft zur Überwindung der Gegenkraft des Rastelements bestimmt ist, da der Spannbügel praktisch ohne Federspannung in Richtung auf die Fahrzeugscheibe mit dem Halterahmen verbunden werden kann. Die Anpresskraft auf das Sensorgehäuse wird erst durch die Verschiebung des Spannbügels erzeugt.The Mounting of the clamp is done here in two steps and first by clipping the tension bracket on the support frame and second, by moving the tension bracket against the Sensor housing. The clip-in of the tension bracket on the support frame can be done with a small amount of force, the essentially by the force required to overcome the counter-force of the locking element is determined, since the clamping bracket practically without spring tension in the direction of the vehicle window with the holding frame can be connected. The contact pressure on the sensor housing is only generated by the displacement of the clamping bracket.
Es stellte sich die Aufgabe, eine weitere Sensoranordnung gemäß des Oberbegriffs zu schaffen, bei der die Befestigung des Sensorgehäuses an der Fahrzeugscheibe mit einer möglichst geringen Montagekraft auskommt.It set itself the task, another sensor arrangement according to the To provide generic term, at the attachment of the sensor housing on the vehicle window with the lowest possible installation force gets along.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zwischen dem Sensorgehäuse und der Flachformfeder mindestens ein verschwenkbar gelagerter Exzenter angeordnet ist, der mit einem Betätigungsarm verbunden ist.These The object is achieved according to the invention that between the sensor housing and the flat form spring at least one pivotably mounted eccentric is arranged, which is connected to an actuating arm.
Die Montage der Flachformfeder erfolgt hier ebenfalls in zwei Montageschritten und zwar erstens durch Einklipsen der Flachformfeder am Halterahmen und zweitens durch das Spannen der Flachformfeder gegen das Sensorgehäuse durch das Verschwenken des Exzenters, wodurch die Anpresskraft auf das Sensorgehäuse erzeugt wird. Das Einklipsen der Flachformfeder am Halterahmen erfordert einen nur geringen Kraftaufwand, da er praktisch ohne Federspannung in Richtung auf die Fahrzeugscheibe mit dem Halterahmen verbunden werden kann.The Assembly of the flat spring takes place here also in two assembly steps and firstly by clipping the flat form spring on the support frame and secondly by tensioning the flat-form spring against the sensor housing by pivoting the eccentric, thereby increasing the contact pressure the sensor housing is generated. The clipping in of the flat form spring on the support frame requires only a small amount of force, as he virtually without spring tension in the direction of the vehicle window with can be connected to the support frame.
Durch den Betätigungsarm, der mit dem Exzenter verbunden ist, wird eine Kraftuntersetzung erreicht, so dass der Kraftaufwand zum Verschwenken des Exzenters ebenfalls gering ist. Hierdurch wird eine komfortable Handhabung bei der Montage erreicht.By the actuating arm, which is connected to the eccentric, a force reduction is achieved, so that the force required for Pivoting the eccentric is also low. This will be a comfortable handling during assembly.
Vorteilhafterweise können zwischen dem Sensorgehäuse und der Flachformfeder auch mehrere verschwenkbare Exzenter vorgesehen sein, die gemeinsam oder nacheinander zum Spannen der Flachformfeder verschwenkt werden. Hierdurch kann, besonders bei einem großflächigen Sensorgehäuse, die Kraft der Flachformfeder besonders gleichmäßig auf die Oberfläche des Sensorgehäuses übertragen werden.advantageously, can be between the sensor housing and the flat spring also several pivotable eccentric be provided in common or be pivoted one after the other for tensioning the flat-form spring. This can, especially in a large area Sensor housing, the force of the flat spring particularly uniform transferred to the surface of the sensor housing become.
