Description

Die Erfindung betrifft eine optoelektronische Sensoreinrichtung zur Erfassung der Benetzung einer Kraftfahrzeugscheibe, mit einem Strahlensender und einem Strahlenempfänger sowie einem der Scheibe zugeordneten, einerseits Strahleneinkoppelbereiche und andererseits Strahlenauskoppelbereiche aufweisenden Strahlenleitkörper.The The invention relates to an optoelectronic sensor device for Detecting the wetting of a motor vehicle window, with a radiation transmitter and a radiation receiver and one of the disc associated, on the one hand Strahleneinkoppelbereiche and on the other hand Strahlauskoppelbereiche having radiator.

Durch die DE 43 18 114 A1 ist eine optoelektronische Sensoreinrichtung bekannt geworden, bei der ein von einem Sender ausgehendes, divergierendes Senderstrahlenbündel über einen der Innenfläche der Kraftfahrzeugscheibe zugeordneten Strahlenleitkörper mittels einer an demselben vorhandenen Linse parallelisiert und in die Kraftfahrzeugscheibe eingekoppelt und nach zumindest einer an der Außenfläche der Scheibe stattfindenden Reflexion wieder aus der Scheibe ausgekoppelt und über eine weitere an dem Strahlenleitkörper vorhandene Linse als konvergierendes Strahlenbündel einem Empfänger zugeführt wird. Der Strahlenleitkörper ist dabei über ein optisches Koppelmedium an der Kraftfahrzeugscheibe befestigt. Da der Strahlenleitkörper in dieser Ausgestaltung eine relativ große Masse aufweist, ist die Verbindung durch das optische Koppelmedium bei den in einem Kraftfahrzeug auftretenden Schwingungen großen Belastungen ausgesetzt, was zu Ablösungen des Strahlenleitkörpers von der Scheibe und damit zu Unterbrechungen in der optischen Ankopplung führen kann.By the DE 43 18 114 A1 an optoelectronic sensor device has become known in which a divergent transmitter beam emanating from a transmitter is parallelized by means of a lens element associated with the inner surface of the vehicle window and coupled into the vehicle window and then retracted after at least one reflection taking place on the outer surface of the window coupled to the disc and is supplied via a further existing on the beam guide lens as a converging beam to a receiver. The beam guide is attached via an optical coupling medium to the vehicle window. Since the Strahlleitkörper in this embodiment has a relatively large mass, the compound is exposed by the optical coupling medium in the vibrations occurring in a motor vehicle large loads, which can lead to detachment of the Strahlleitkörpers of the disc and thus to interruptions in the optical coupling.

Durch die DE 197 20 874 C2 ist eine gattungsgemäße optoelektronische Sensoreinrichtung bekannt, bei der die Ein- und Auskopplung der Lichtstrahlen durch an der Innenseite der Scheibe vorhandene Profilierungen erfolgt, wobei diese Profilierungen entweder direkt in der Scheibe oder in einer durch eine optische Klebeverbindung mit der Scheibe verbundenen Folie realisiert sind.By the DE 197 20 874 C2 a generic optoelectronic sensor device is known, in which the coupling and decoupling of the light beams takes place by existing on the inside of the disc profilings, which profilings are realized either directly in the disc or in a connected by an optical adhesive connection to the disc foil.

Da die Parallelisierung und Fokussierung der Strahlen bei der zuletzt genannten Einrichtung durch einen von dem zur Ein- und Auskopplung der Lichtstrahlen vorgesehenen ersten Strahlenleitkörper separat ausgebildeten zweiten Strahlenleitkörper erfolgt, kann der erste Strahlenleitkörper eine geringe Masse aufweisen und daher sicherer an der Scheibe befestigt werden oder sogar gleich durch einen Teil der Scheibe selbst gebildet sein. Im ersten Fall bestehen jedoch die generellen Probleme der optischen Ankopplung wie mögliche Ablösungen oder Einschluß von Blasen oder Fremdkörpern in der Verbindungsschicht nach wie vor, im zweiten Fall müßte ein an den Herstellungsprozeß der Scheibe anschließendes Verfahren zur Erzeugung der Profilierungen in derselben vorgesehen werden, welches zum einen aufwendig und zum anderen mit der Gefahr der Zerstörung der fertigen Scheibe verbunden wäre.There the parallelization and focusing of the rays at the last said device by one of the for coupling and decoupling the light beams provided first Strahlleitkörper separately trained second beam guide body, the first light conducting have a low mass and therefore safer attached to the disc be formed or even equal by a part of the disk itself be. In the first case, however, there are the general problems of optical coupling as possible detachments or inclusion of Bubbles or foreign bodies in the connecting layer as before, in the second case would be on the manufacturing process of Slice adjoining Method for producing the profilings provided in the same which, on the one hand consuming and on the other with the danger of destruction the finished disc would be connected.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine gattungsgemäße Einrichtung in der Weise weiterzubilden, daß die zum Stand der Technik genannten Nachteile vermieden sind.task The present invention is therefore a generic device to develop in such a way that the The disadvantages mentioned in the prior art are avoided.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Scheibe eine durch eine Innen- und eine Außenscheibe unter Zwischenlage einer Kunststoffschicht gebildete Verbundglasscheibe ist, und daß der Strahlenleitkörper in eine in der Innenscheibe der Verbundglasscheibe gebildete Ausnehmung eingesetzt ist.These The object is achieved according to the invention in that the disc by a Inner and outer pane Laminated glass formed with the interposition of a plastic layer is, and that the light conducting in a recess formed in the inner pane of the laminated glass pane is used.

Ein besonderer Vorteil der erfindungsgemäßen Einrichtung besteht darin, daß die Montage des zur Ein- und Auskopplung der Strahlung vorgesehenen Strahlenleitkörpers in den Herstellungsprozeß der Scheibe integriert werden kann, und somit für die optische Verbindung des Strahlenleitkörpers mit der Scheibe die gleichen Qualitätsmaßstäbe einzuhalten sind wie für die Scheibe selbst.One particular advantage of the device according to the invention is that the Mounting the intended for coupling and decoupling of the radiation beam control in the manufacturing process of Disk can be integrated, and thus for the optical connection of the beam control to comply with the same quality standards as for the disc even.

Als Strahlenleitkörper kann hierbei sowohl ein etwa mittels Profilierungen allein zur Ein- und Auskopplung der Strahlen vorgesehenes Element als auch ein zusätzlich schon mit Mitteln zur Parallelisierung und Fokussierung der Strahlen etwa in Form von Linsen versehenes Gebilde zum Einsatz kommen.When light conducting Here, for example, a profile can be used alone to and decoupling of the rays provided element as well as an additional already with means for parallelization and focusing of the rays approximately come in the form of lenses provided structures.

Verbundglasscheiben werden heutzutage sehr häufig als sogenanntes Wärmedämmglas eingesetzt, bei dem zumeist die Außenscheibe klar und die Innenscheibe mit einem den infraroten Anteil des Lichtspektrums absorbierenden Material eingefärbt ist. Bei den in der Regel mit einer Strahlung im nahen Infrarotbereich arbeitenden Sensoreinrichtungen der hier angesprochenen Art führt dies zu Funktionsproblemen, die bei der vorliegenden Erfindung durch das Fehlen der Innenscheibe im Bereich der Sensoreinrichtung in vorteilhafter Weise vermieden sind.Laminated glass become very common nowadays used as so-called thermal insulating glass, in most cases the outer pane clear and the inner pane with a the infrared portion of the light spectrum colored absorbing material. In the case of the usually with a radiation in the near infrared range operating sensor devices of the type mentioned here, this leads to functional problems that in the present invention by the absence of the inner pane in the area of the sensor device in advantageously avoided.

Nachfolgend ist die Erfindung anhand eines Ausführungsbeispiels unter Bezugnahme auf die beigefügten Figuren beschrieben. Es zeigen:following the invention with reference to an embodiment with reference on the attached Figures described. Show it:

1: einen Schnitt durch eine Kraftfahrzeugscheibe vor dem Herstellen des Verbundes mit einer mit Profilierungen versehenen Platte als Strahlenleitkörper 1 a section through a motor vehicle window before producing the composite with a plate provided with profilings as beam guide

2: einen Schnitt durch eine fertige Krafffahrzeugscheibe mit einem mit Linsen versehenen Strahlenleitkörper 2 a section through a finished Krafffahrzeugscheibe with a lensed light conducting

3: einen Schnitt durch eine fertige Kraftfahrzeugscheibe mit einem Strahlenleitkörper mit einer alternativen Befestigung 3 a section through a finished vehicle window with a beam guide with an alternative attachment

Bei der zur Aufnahme der erfindungsgemäßen Sensoreinrichtung vorgesehenen Kraftfahrzeugscheibe 1 handelt es sich um eine üblicherweise für Windschutzscheiben eingesetzte Verbundglasscheibe. Eine solche besteht, wie aus der Zeichnung zu ersehen, aus einer Innenscheibe 3 und einer Außenscheibe 4, die mittels einer eine Haftung vermittelnden, weichen Kunststoffschicht 5 etwa aus PVB als Zwischenlage miteinander verbunden sind. In dem zur Aufnahme der Sensoreinrichtung vorgesehenen Bereich der Scheibe 1 ist in der Innenscheibe 3 eine Ausnehmung 3' eingebracht, die in ihrer Kontur der Außenkontur des dort einzusetzenden Strahlenleitkörpers 2, 2* entspricht. Aus Gründen einer praktischen Erzeugbarkeit der Ausnehmung 3' in der in der Regel aus Glas bestehenden Innenscheibe 3 wird diese Kontur vorzugsweise rund sein.In the intended for receiving the sensor device according to the invention vehicle window 1 it is a laminated glass pane commonly used for windshields. Such exists, as can be seen from the drawing, from an inner pane 3 and an outer pane 4 , by means of a mediating adhesion, soft plastic layer 5 are interconnected, for example, of PVB as an intermediate layer. In the area provided for receiving the sensor device area of the disc 1 is in the inner pane 3 a recess 3 ' introduced, in their contour of the outer contour of the beam guide body to be used there 2 . 2 * equivalent. For reasons of practical producibility of the recess 3 ' in the usually made of glass inner pane 3 this contour will preferably be round.

Bei dem in 1 dargestellten Strahlenleitkörper 2 handelt es sich um eine mit Profilierungen versehene Platte, die paßgenau in die Ausnehmung 3' in der Innenscheibe 3 eingesetzt wird. Vorzugsweise geschieht dies direkt beim Herstellungsprozeß der Scheibe 1 vor der Behandlung im sog. Autoklaven, in dem unter Druck und erhöhter Temperatur der Verbund zwischen den Glasscheiben 3, 4 und der aus einer PVB-Folie bestehenden Zwischenschicht 5 erzeugt wird. Nach der Behandlung im Autoklaven ist der Strahlenleitkörper 2, der in diesem Falle ebenfalls aus Glas besteht, dann quasi Bestandteil der Verbundglasscheibe 1. Bei dieser Ausführungsform läßt sich der Stahlenleitkörper 2 vorteilhaft so bemessen, daß er mit der Oberfläche der Innenscheibe 3 bündig abschließt, so daß auch hinsichtlich des Transportes und der Lagerung der Scheibe 1 keinerlei Nachteile gegenüber herkömmlichen Scheiben bestehen.At the in 1 illustrated beam guide 2 it is a profiled plate, the exact fit in the recess 3 ' in the inner pane 3 is used. This is preferably done directly during the manufacturing process of the disc 1 before treatment in the so-called autoclave, in which under pressure and elevated temperature, the bond between the glass panes 3 . 4 and the intermediate layer consisting of a PVB film 5 is produced. After treatment in the autoclave is the Strahlleitkörper 2 , which in this case also consists of glass, then virtually a component of the laminated glass pane 1 , In this embodiment, the Stahlenleitkörper can be 2 Advantageously sized so that it matches the surface of the inner pane 3 flush closes, so that also with regard to the transport and storage of the disc 1 There are no disadvantages compared to conventional discs.

In 2 ist eine Ausführungsform mit einem Strahlenleitkörper 2* dargestellt, an dem Linsen zur Parallelisierung und Fokussierung der Strahlen gleich angeformt sind. Dieser Strahlenleitkörper 2* trägt im Vergleich zu dem in 1 gezeigten zwar etwas über die normale Scheibendicke hinaus auf, dafür sind aber hierbei keine zusätzlichen Elemente zur Strahlformung erforderlich. Da dieser Strahlenleitkörper 2* ein größeres Volumen aufweist, ist er zur Vermeidung einer zu großen Masse aus Kunststoff hergestellt. Die zum Scheibenverbund vorhandene PVB-Folie 5 ist in diesem Falle kein geeignetes Verbindungsmedium für Außenscheibe 4 und Strahlenleitkörper 2*, so daß im Bereich des Strahlenleitkörpers 2* auch in der PVB-Folie 5 ein Ausschnitt gebildet ist, in dem ein Folienstück 5' aus einem geeigneten Material wie z.B. Polyurethan eingesetzt ist.In 2 is an embodiment with a beam guide 2 * represented on the lenses for parallelization and focusing of the rays are integrally formed. This beam guide 2 * carries in comparison to the in 1 Although shown somewhat beyond the normal pane thickness, but here are no additional elements for beam forming required. As this beam guide 2 * has a larger volume, it is made to avoid too much mass of plastic. The PVB film available for the laminated pane 5 is not a suitable connection medium for outer pane in this case 4 and radiation guide 2 * , so that in the region of the beam guide 2 * also in the PVB film 5 a cutout is formed in which a piece of foil 5 ' made of a suitable material such as polyurethane is used.

An den einzusetzenden Strahlenleitkörpern 2, 2* können bei Bedarf auch noch zusätzliche Elemente zur einfachen mechanischen Befestigung weiterer Komponenten der Sensoreinrichtung vorhanden sein, so daß auch eine leichte und sichere Montage der gesamten Einrichtung gewährleistet ist.At the beam guiding bodies to be used 2 . 2 * If necessary, additional elements for simple mechanical attachment of other components of the sensor device may be present, so that an easy and secure installation of the entire device is ensured.

3 zeigt eine alternative Befestigungsmöglichkeit für den Strahlenleitkörper 2 an der Scheibe 1. Hier ist in die Ausnehmung 3' in der Innenscheibe 3 ein Halterahmen 6 eingesetzt. Im Bereich der Ausnehmung 3' ist auch die als Zwischenschicht fungierende PVB-Folie 5 ausgespart, und zwar so weit, daß ein Hintergreifen der Öffnung der Innenscheibe 3 durch einen Sockelabschnitt 6' des Halterahmens 6 möglich ist. Der Halterahmen 6 besteht aus Metall oder Kunststoff und ist mit Befestigungselementen 9 zur Montage des Strahlenleitkörpers 2 und/oder ggf. weiterer Komponenten der Sensoreinrichtung versehen. Der Sockelabschnitt 6' des Halterahmens 6 ist in seiner Dicke so bemessen, wie es die Dicke der PVB-Folie 5 nach Herstellung des Scheibenverbundes vorgibt. Da die PVB-Folie 5 als Koppelmedium für die optische Ankopplung des Strahlenleitkörpers 2 in diesem Falle nicht vorhanden ist, muß dieser mit einem separaten Koppelmedium versehen sein, welches z.B. aus einem elastischen, optisch transparenten Folienstück 7 besteht, das erforderlichenfalls auf einer oder beiden Seiten Klebeeigenschaften aufweisen kann. Das Folienstück 7 kann selbstverständlich auch hier wie im zuvor beschriebenen Beispiel aus Polyurethan bestehen und bereits beim Produktionsprozeß der Scheibe im Autoklaven den Verbund zwischen Außenscheibe 4 und Strahlenleitkörper 2 herstellen. 3 shows an alternative mounting option for the beam guide 2 at the disc 1 , Here is in the recess 3 ' in the inner pane 3 a support frame 6 used. In the area of the recess 3 ' is also the acting as an intermediate layer PVB film 5 recessed, and indeed so far that a gripping behind the opening of the inner pane 3 through a base section 6 ' of the holding frame 6 is possible. The support frame 6 is made of metal or plastic and has fasteners 9 for mounting the beam guide 2 and / or possibly further components of the sensor device. The base section 6 ' of the holding frame 6 is sized in its thickness, as is the thickness of the PVB film 5 pretends after production of the disc composite. Because the PVB film 5 as a coupling medium for the optical coupling of the beam guide 2 in this case does not exist, it must be provided with a separate coupling medium, which, for example, from an elastic, optically transparent film piece 7 which may, if necessary, have adhesive properties on one or both sides. The foil piece 7 can of course also here as in the example described above made of polyurethane and already in the production process of the disc in the autoclave, the composite between the outer pane 4 and radiation guide 2 produce.

Eine z.B. an der Innenseite der Außenscheibe 4 vorhandene optionale Bedruckung 8 kann zur visuellen Kaschierung der Sensoreinrichtung dienen. Diese Bedruckung 8, welche zumeist als schwarzes Glas-Email ausgeführt ist, weist dabei eine Ausnehmung 8' auf, die im wesentlichen mit der Ausnehmung 3' in der Innenscheibe 3 fluchtet, um die optische Funktion der Sensoreinrichtung zu gewährleisten, aber den Rand derselben noch überdeckt, so daß die Trennstelle zwischen Innenscheibe 3 und Strahlenleitkörper 2, 2* von außen nicht erkennbar ist.For example, on the inside of the outer pane 4 existing optional printing 8th can serve for visual lamination of the sensor device.
