Abstract
Description
Die Erfindung betrifft eine Verbundglaseinheit aus mindestens zwei miteinander verbundenen transparenten Glasscheiben. Sie betrifft weiter ein Kraftfahrzeug mit einer solchen Verbundglaseinheit.The invention relates to a laminated glass unit comprising at least two interconnected transparent glass panes. It further relates to a motor vehicle with such a laminated glass unit.
Derartige Verbundglaseinheiten werden beispielsweise als Front- oder Heckscheiben in Kraftfahrzeugen eingesetzt. Zunehmend wird versucht, den Platz auf der Front- oder Heckscheibe für optische Anzeigeelemente zu nutzen, beispielsweise in Form von Head-up-Displays.Such laminated glass units are used for example as front or rear windows in motor vehicles. Increasingly, attempts are being made to use the space on the front or rear window for optical display elements, for example in the form of head-up displays.
Aus der
Aufgabe der Erfindung ist es, eine technisch einfache Verbundglaseinheit anzugeben, die sich zur Anzeige optischer Informationen eignet und die derart aufgebaut ist, dass sie gesetzlichen Auflagen entspricht.The object of the invention is to provide a technically simple laminated glass unit, which is suitable for displaying optical information and which is constructed such that it complies with legal requirements.
Diese Aufgabe wird gelöst mit dem Gegenstand der unabhängigen Ansprüche. Weitere Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the subject matter of the independent claims. Further embodiments are the subject of the dependent claims.
Gemäß einem Aspekt der Erfindung wird eine Verbundglaseinheit angegeben, die zumindest eine erste transparente Glasscheibe und eine mit der ersten Glasscheibe mittels zumindest einer Zwischenschicht zu einem Verbund laminierte zweite transparente Glasscheibe aufweist. Zwischen der ersten Glasscheibe und der zweiten Glasscheibe ist ein Anzeigeelement angeordnet, das zumindest eine flexible Leiterplatte sowie auf der flexiblen Leiterplatte angeordnete Leuchtdioden aufweist.According to one aspect of the invention, a laminated glass unit is provided which has at least a first transparent glass pane and a second transparent glass pane laminated to the first glass pane by means of at least one intermediate layer in a composite. Between the first glass pane and the second glass pane, a display element is arranged, which has at least one flexible printed circuit board and arranged on the flexible printed circuit board LEDs.
Die Verbundglaseinheit hat den Vorteil, dass sie für das Anzeigeelement relativ kostengünstige Bauteile verwendet, die zudem technisch einfach zu verbauen und zu betreiben sind. Insbesondere können herkömmliche Leuchtdioden (LED) eingesetzt werden. Diese sind mit derart kleinen Abmessungen erhältlich, dass der zwischen den Lagen einer verbundglasscheibe vorhandene Bauraum ausreicht, um sie aufzunehmen. Durch ihre Anordnung auf und Kontaktierung durch eine flexible Leiterplatte wird es ermöglicht, das Anzeigeelement in gewölbte Bereiche von Verbundglasscheiben einzubauen. Es ist demnach nicht notwendig, dass die LEDs selbst flexibel sind, wie das bei TOLEDs der Fall ist. Sie werden vielmehr ausreichend klein gewählt und auf der flexiblen Leiterplatte angeordnet.The laminated glass unit has the advantage that it uses relatively inexpensive components for the display element, which are also technically easy to install and operate. In particular, conventional light emitting diodes (LED) can be used. These are available with such small dimensions that the space available between the layers of a laminated glass pane is sufficient to accommodate them. Their arrangement on and contacting by a flexible printed circuit board makes it possible to install the display element in curved areas of laminated glass panes. It is therefore not necessary that the LEDs themselves are flexible, as is the case with TOLEDs. Instead, they are chosen to be sufficiently small and arranged on the flexible printed circuit board.
Die Verbundglaseinheit kann insbesondere als Verbund-Sicherheitsglas-Einheit ausgebildet sein und eine reißfeste und zähelastische Folie, beispielsweise aus Polyvinylbutyral (PVB), zwischen den Glasscheiben aufweisen.The laminated glass unit can in particular be designed as a composite safety glass unit and have a tear-resistant and viscoelastic film, for example of polyvinyl butyral (PVB), between the glass panes.
In einer Ausführungsform weist die flexible Leiterplatte eine Polyimid-Folie auf. Polyimid-Folien haben den Vorteil, dass sie gegenüber den alternativen PET- und PEN-Folien eine höhere Temperaturbelastbarkeit aufweisen. Sie sind dadurch gegenüber Lötprozessen unempfindlich und weisen einen besonders großen Betriebstemperaturbereich auf. Die hohe Temperaturbelastbarkeit ist insbesondere vorteilhaft beim Einbau in Verbundglaseinheiten, da eine derartige Leiterplatte den Laminierprozess der zumindest zwei Glasscheiben, der bei hohen Drücken und Temperaturen durchgeführt wird, unbeschadet übersteht.In one embodiment, the flexible circuit board comprises a polyimide film. Polyimide films have the advantage that they have a higher temperature resistance than the alternative PET and PEN films. They are thus insensitive to soldering processes and have a particularly large operating temperature range. The high temperature resistance is particularly advantageous when installed in laminated glass units, since such a printed circuit board survives the laminating process of the at least two glass sheets, which is carried out at high pressures and temperatures, unscathed.
In einer Ausführungsform sind die Leuchtdioden als anorganische Leuchtdioden ausgebildet. Unter anorganischen Leuchtdioden werden hier und im Folgenden Leuchtdioden verstanden, die nicht als organische Leuchtdioden ausgebildet sind. Bei dieser Ausführungsform sind demnach gängige und kostengünstig erhältliche Leuchtdioden einsetzbar.In one embodiment, the LEDs are formed as inorganic light emitting diodes. Inorganic light-emitting diodes are understood here and below as light-emitting diodes which are not designed as organic light-emitting diodes. In this embodiment, therefore, common and inexpensive available light emitting diodes can be used.
In einer Ausführungsform ist die Leiterpatte L-förmig ausgebildet und weist einen ersten Schenkel und einen dazu gewinkelten zweiten Schenkel auf. Wie sich herausgestellt hat, können bei einer solchen Ausbildung der Leiterplatte die darauf anzuordnenden LEDs sowie eine Kontaktiermöglichkeit des Anzeigeelements platzsparend auf möglichst wenig Fläche untergebracht werden.In one embodiment, the conductor plate is L-shaped and has a first leg and an angled second leg thereto. As has been found, in such a design of the circuit board, the LEDs to be arranged thereon as well as a contacting possibility of the display element can be accommodated on as little space as possible to save space.
Beispielsweise können die LEDs in einer Reihe auf dem ersten Schenkel der L-förmigen Leiterplatte angeordnet sein. Der zweite Schenkel der L-förmigen Leiterplatte kann zur Kontaktierung des Anzeigeelements vorgesehen sein. Insbesondere kann der zweite Schenkel einen Nullkraftstecker aufweisen, der mit einer Stromversorgung außerhalb der Verbundglaseinheit zuverlässig verbindbar ist.For example, the LEDs may be arranged in a row on the first leg of the L-shaped printed circuit board. The second leg of the L-shaped circuit board may be provided for contacting the display element. In particular, the second leg can have a zero-force plug, which can be reliably connected to a power supply outside the laminated glass unit.
In einer Ausführungsform ist die flexible Leiterplatte transparent ausgebildet. Das hat den Vorteil, dass sie die Sicht durch die Verbundglaseinheit nicht behindert.In one embodiment, the flexible printed circuit board is transparent. This has the advantage that it does not hinder the view through the laminated glass unit.
Alternativ kann die flexible Leiterplatte jedoch auch opak ausgebildet sein. Opake Leiterplatten sind unter Umständen kostengünstiger und es ist eine größere Auswahl an möglichen Materialien vorhanden, so dass eine bessere Anpassung an die Einsatzbedingungen möglich ist.Alternatively, however, the flexible printed circuit board may also be opaque. Opaque boards may be cheaper and there is a wider choice of materials available, so that a better adaptation to the conditions of use is possible.
In einer Ausführungsform ist die Verbundglaseinheit als Außenverglasung eines Kraftfahrzeugs ausgebildet, insbesondere als Front- bzw. Windschutzscheibe oder als Heckscheibe. Derartige Scheiben werden meist als Verbundsicherheitsglas ausgebildet aus zwei Glasscheiben mit einer reißfesten Klebefolie dazwischen. Diese Anordnung eignet sich zur Aufnahme des Anzeigeelements. Das Anzeigeelement kann dann beispielsweise zur Ausgabe von Warnsignalen an den Fahrer dienen.In one embodiment, the laminated glass unit is designed as exterior glazing of a motor vehicle, in particular as a front or windshield or as a rear window. Such discs are usually formed as a laminated safety glass of two glass sheets with a tear-resistant adhesive film in between. This arrangement is suitable for receiving the display element. The display element can then serve, for example, to output warning signals to the driver.
Dabei können wesentliche Bereiche des Anzeigeelements im Bereich eines Schwarzdruckes der Außenverglasung angeordnet sein. Ein solcher Schwarzdruck ist insbesondere bei Frontscheiben zur Ausblendung störenden Streulichts im äußersten Randbereich der Scheibe vorgesehen. Der Schwarzdruck verdeckt außerdem bei geklebten Scheiben den Kleberand und verhindert eine vorzeitige Alterung des Klebers durch Lichteinwirkung. Die Anordnung des Anzeigeelements in diesem Bereich hat den Vorteil, dass das Sichtfeld des Fahrers nicht eingeschränkt wird.In this case, essential areas of the display element can be arranged in the region of a black print of the exterior glazing. Such a black print is provided in particular in windscreens for suppressing disturbing scattered light in the outermost edge region of the disk. The black print also obscures the adhesive edge on glued windows and prevents premature aging of the adhesive due to exposure to light. The arrangement of the display element in this area has the advantage that the field of view of the driver is not restricted.
In einer Ausführungsform ist der Schwarzdruck gerastert ausgebildet und die Außenverglasung ist im Bereich der einzelnen LEDs transparent ausgebildet. Unter einer gerasterten Ausbildung wird hier und im Folgenden verstanden, dass der Schwarzdruck zumindest in einem Übergangsbereich zwischen vollständig schwarzer und vollständig transparenter Außenverglasung in einem Muster, beispielsweise einem Punktmuster, aufgebracht ist, wobei zwischen den einzelnen Musterelementen die Außenverglasung vollständig transparent ist.In one embodiment, the black print is screened and the exterior glazing is transparent in the region of the individual LEDs. A screened embodiment is understood here and below as meaning that the black print is applied in a pattern, for example a dot pattern, at least in a transition region between completely black and completely transparent outer glazing, wherein the outer glazing is completely transparent between the individual pattern elements.
In der beschriebenen Ausführungsform wird das Anzeigeelement zwar im Bereich des Schwarzdrucks angeordnet, jedoch werden die einzelnen LEDs so platziert, dass sie zwischen einzelnen Punkten des Rasters sichtbar sind. Auf diese Weise kann erreicht werden, dass das Anzeigeelement die Sicht des Fahrers nicht behindert, es aber trotzdem gut sichtbar ist.Although the display element is placed in the region of black printing in the described embodiment, the individual LEDs are placed so that they are visible between individual points of the grid. In this way it can be achieved that the display element does not hinder the driver's view, but it is still clearly visible.
In einer Ausführungsform weist die Verbundglaseinheit eine Innenscheibe und eine Außenscheibe auf. Die Innenscheibe ist dabei zur Fahrerkabine gewandt und die Außenscheibe nach außen zur Umgebung des Kraftfahrzeugs. Der Schwarzdruck ist auf der Außenscheibe aufgebracht. Das Anzeigeelement ist in einem Bereich angeordnet, in dem die Außenscheibe vollständig opak ist. Bei dieser Ausführungsform kann das Anzeigeelement in einem äußersten Randbereich der Verbundglaseinheit angeordnet sein und damit nicht mehr in einem Bereich, in dem es die Sicht des Fahrers beeinträchtigt. Bei dieser Ausführungsform ist das Anzeigeelement nur nach innen sichtbar, kann aber damit zur Anzeige von Informationen für einen Fahrer oder andere Personen innerhalb des Kraftfahrzeugs genutzt werden und schränkt die Sicht des Fahrers durch die Frontscheibe in keiner Weise ein.In one embodiment, the laminated glass unit has an inner pane and an outer pane. The inner pane is turned to the driver's cab and the outer pane to the outside to the environment of the motor vehicle. The black print is applied to the outer pane. The display element is arranged in a region in which the outer pane is completely opaque. In this embodiment, the display element can be arranged in an outermost edge region of the laminated glass unit and thus no longer in an area in which it affects the driver's view. In this embodiment, the display element is visible only inwardly, but can thus be used to display information for a driver or other persons within the motor vehicle and does not restrict the driver's view through the windscreen in any way.
Gemäß einem Aspekt der Erfindung wird ein Kraftfahrzeug mit der beschriebenen Verbundglaseinheit angegeben.According to one aspect of the invention, a motor vehicle is specified with the described laminated glass unit.
Dabei kann insbesondere der zweite Schenkel der L-förmig ausgebildeten Leiterplatte einen Nullkraftstecker für eine Stromversorgung aufweisen. Derartige Nullkraftstecker werden zunehmend zur Kontaktierung von Baugruppen eingesetzt.In this case, in particular, the second leg of the L-shaped printed circuit board having a zero force connector for a power supply. Such zero force connectors are increasingly used for contacting assemblies.
Die Verwendung einer flexiblen Leiterplatte ermöglicht es, einen Bereich der Leiterplatte für einen direkten Stromanschluss zu nutzen. Dabei ermöglichen Nullkraftstecker (engl. Zero Insertion Force Connector, ZIF Connector) eine robuste, sichere Verbindung mittels eines Verriegelungssystems, wobei die Verbindung ohne Druck- und Steckkräfte auf die Kontakte erfolgt.The use of a flexible circuit board makes it possible to use an area of the circuit board for a direct power connection. Zero Insertion Force Connector (ZIF Connector) enables a robust, secure connection by means of a locking system, whereby the connection takes place without pressure and insertion forces on the contacts.
In einer Ausführungsform weist das Kraftfahrzeug zumindest einen Sensor zur Erfassung von Gefahrensituationen sowie zumindest eine Steuereinheit zur Erzeugung von Warnsignalen auf, wobei die Warnsignale einem Fahrer mittels des in der Verbundglaseinheit angeordneten Anzeigeelements anzeigbar sind.In one embodiment, the motor vehicle has at least one sensor for detecting dangerous situations and at least one control unit for generating warning signals, wherein the warning signals can be displayed to a driver by means of the display element arranged in the laminated glass unit.
Bei dieser Ausführungsform wird das Anzeigeelement für die Ausgabe von Warnsignalen genutzt. Insbesondere können Kollisionswarnungen ausgegeben werden, beispielsweise in Form von rot aufleuchtenden LEDs. Derartige Warnungen sind wegen der Nähe zum Sichtfeld des Fahrers in der Frontscheibe sehr gut wahrnehmbar.In this embodiment, the display element is used for issuing warning signals.
