Abstract
Description
Die Erfindung betrifft ein Anzeigeelement für einen Rückspiegel eines Fahrzeuges nach dem Oberbegriff des Patentanspruches 1.The invention relates to a display element for a rearview mirror of a vehicle according to the preamble of claim 1.
Es sind bei Fahrzeugen bereits beheizbare Außenspiegel bekannt, die insbesondere bei beschlagenen oder vereisten Außenspiegeln für eine freie Sicht sorgen sollen. Die Heizung derartiger Außenspiegel ist entweder manuell einschaltbar oder wird selbsttätig in Abhängigkeit von der Umgebungstemperatur und/oder der Temperatur der Spiegelfläche aktiviert. Der Anmelderin ist es bekannt, für die Einschaltdauer der Heizung eine zeitliche Obergrenze vorzusehen.Heated exterior mirrors are already known in vehicles, which is particularly the case with fogged or icy exterior mirrors should provide a clear view. Heating such Outside mirror can either be switched on manually or will automatically depending on the ambient temperature and / or the temperature of the mirror surface activated. The Applicant is known for the duty cycle of the heater to provide a time limit.
Ausgehend von diesem Stand der Technik weist die vorliegende Erfindung ein Anzeigeelement für einen Rückspiegel eines Fahrzeugs auf, wobei das Anzeigeelement auf die Spiegelfläche aufgebracht wird und wobei das Anzeigeelement bei Umgebungstemperatur zumindest im wesentlichen durchsichtig ist oder eine erste Farbe aufweist und bei Überschreiten einer bestimmten Mindesttemperatur farbig bzw. dunkel wird oder eine zweite Farbe aufweist, wobei bei einem nachfolgenden Unterschreiten der Mindesttemperatur das Anzeigeelement wieder zumindest im wesentlichen durchsichtig wird oder die erste Farbe aufweist.Based on this prior art, the present Invention a display element for a rear view mirror Vehicle on, with the display element on the mirror surface is applied and the display element at Ambient temperature is at least essentially transparent or has a first color and if one is exceeded certain minimum temperature becomes colored or dark or a second color, with a subsequent The display element falls below the minimum temperature again at least essentially becomes transparent or the first Has color.
Vorteilhaft zeigt sich bei der vorliegenden Erfindung, daß die Temperatur der Spiegelfläche als direkte Funktionskontrolle der Heizung des Spiegels wahrnehmbar wird. Insbesondere kann die Mindesttemperatur so eingestellt werden, daß erkennbar wird, ob die Heizung des Spiegels eingeschaltet ist oder nicht. The present invention advantageously shows that the Temperature of the mirror surface as a direct function check of the Heating of the mirror becomes noticeable. In particular, the Minimum temperature must be set so that it can be seen whether the mirror heater is turned on or not.
Vorteilhaft wird dabei für den Benutzer erkennbar, ob die Heizung des Spiegels funktioniert oder nicht. Dazu ist es auch wesentlich, daß die Verfärbung bzw. Verdunklung oder der Farbumschlag des Anzeigeelements reversibel ist. Die Darstellung mittels des Thermocolour-Effektes kann erfolgen, indem eine Umstellung von durchsichtig auf farbig bzw. dunkel erfolgt oder indem sich die Farbe des Symbols ändert.It is advantageous for the user to recognize whether the Heating the mirror works or not. It is also for that essential that the discoloration or darkening or Color change of the display element is reversible. The Representation by means of the thermocolor effect can take place by changing from transparent to colored or dark or by changing the color of the symbol.
In diesem Zusammenhang sei in Kenntnis der Erfindung ergänzend auf Stand der Technik hingewiesen, aus dem entsprechende Ausgestaltungen des Anzeigeelement entnommen werden können. Hierzu sei auf die DE 28 15 172 A1 verwiesen, auf die DE 38 36 424 A1, die DE 298 09 495 U1 und/oder die DE 29 35 472 A1.In this context, knowledge of the invention should be supplementary referred to the state of the art, from the corresponding Embodiments of the display element can be removed. For this purpose, reference is made to DE 28 15 172 A1, to which DE 38 36 424 A1, DE 298 09 495 U1 and / or DE 29 35 472 A1.
Bei dem Anzeigeelement nach Anspruch 2 ist das Anzeigeelement nur auf einem Teil der Spiegeloberfläche aufgebracht.In the display element according to claim 2, the display element only applied to part of the mirror surface.
Dadurch wird vorteilhaft erreicht, daß auch bei eingeschalteter Heizung nach Möglichkeit eine hinreichende Sichtfläche nach hinten gewährleistet ist.This advantageously ensures that even when switched on Heating, if possible, a sufficient visible area back is guaranteed.
Gemäß Anspruch 3 symbolisiert das Anzeigeelement Heizelemente des Spiegels.According to claim 3, the display element symbolizes heating elements of the mirror.
Dadurch wird die Funktion der Anzeige durch die Darstellung des Symbols für den Fahrzeugführer besonders gut wahrnehmbar.This means that the function of the display is represented by the Symbols particularly well perceptible to the driver.
Bei dem Anzeigeelement nach Anspruch 4 liegt die Mindesttemperatur oberhalb von 308 K, insbesondere oberhalb von 313 K.In the display element according to claim 4 is Minimum temperature above 308 K, especially above 313 K.
Die Temperatur von 308 K entspricht einer Temperatur, die nur vergleichsweise selten überschritten wird. Gleichzeitig ist bei dieser Temperatur sichergestellt, daß Sie unter der Körpertemperatur von Menschen liegt, so daß also durch das Anzeigeelement auch sichtbar wird, wann das Berühren der Spiegelfläche als unangenehm empfunden werden kann. Bei der Temperatur von 313 K ist noch weitgehender sichergestellt, daß diese normalerweise nicht überschritten wird. Gleichzeitig ist diese nicht sehr viel wärmer als die Körpertemperatur, so daß das Berühren der Spiegeloberfläche noch nicht zu unangenehm ist.The temperature of 308 K corresponds to a temperature that only is rarely exceeded. At the same time this temperature ensures that you are below the Body temperature of people lies, so that by that Display element also becomes visible when touching the Mirror surface can be felt as uncomfortable. In the Temperature of 313 K is more largely ensured that this is normally not exceeded. At the same time these are not much warmer than body temperature, so that not too uncomfortable to touch the mirror surface is.
Die entsprechende Mindesttemperatur kann durch die Wahl und Ausgestaltung eines geeigneten Kristalls vorgegeben werden.The corresponding minimum temperature can be selected and Design of a suitable crystal can be specified.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigt dabei im einzelnen:An embodiment of the invention is in the drawing shown. It shows in detail:
Fig. 1 einen Rückspiegel mit einem Anzeigeelement, wobei die Spiegelfläche eine Temperatur oberhalb der Mindesttemperatur aufweist, Fig. 1 is a rearview mirror with a display element, wherein the mirror surface has a temperature above the minimum temperature,
Fig. 2 einen Teil des Rückspiegels, wobei die Spiegelfläche Umgebungstemperatur aufweist, und Fig. 2 shows a part of the rearview mirror, the mirror surface having ambient temperature, and
Fig. 3 einen Teil des Rückspiegels, wenn die Spiegelfläche eine Temperatur oberhalb der Mindesttemperatur aufweist. Fig. 3 shows a part of the rearview mirror when the mirror surface has a temperature above the minimum temperature.
Fig. 1 zeigt einen Rückspiegel 1, auf dem ein Anzeigeelement 2 aufgebracht ist. Dieses Anzeigeelement 2 ist bei einer Temperatur, die der Umgebungstemperatur entspricht, zumindest im wesentlichen durchsichtig. Dies bedeutet, daß dann beispielsweise noch eine schwache Kontur sichtbar ist, die aber nur bei genauerer Betrachtung erkennbar ist. In der Darstellung der Fig. 1 ist das Anzeigeelement 2 sichtbar. Das bedeutet, daß die Temperatur der Spiegeloberfläche größer ist als die Mindesttemperatur. Die Heizung einer Spiegelfläche kann deren Temperatur bis auf etwa 325 K bis 340 K erhitzen. Indem also die Mindesttemperatur entsprechend eingestellt wird, kann die Funktion der Heizung kontrolliert werden und das Symbol als Warnhinweis auf das erhitzte Spiegelglas verwendet werden. Fig. 1 shows a rearview mirror 1 , on which a display element 2 is applied. This display element 2 is at least essentially transparent at a temperature which corresponds to the ambient temperature. This means that, for example, a weak contour is then still visible, but can only be recognized on closer inspection. In the illustration of Fig. 1 the display element 2 is visible. This means that the temperature of the mirror surface is higher than the minimum temperature. The heating of a mirror surface can heat its temperature up to about 325 K to 340 K. By setting the minimum temperature accordingly, the function of the heater can be checked and the symbol can be used as a warning on the heated mirror glass.
Fig. 2 zeigt einen Ausschnitt des Spiegels 1, wenn die Temperatur der Spiegeloberfläche unterhalb der Mindesttemperatur ist. Das Anzeigeelement 2 ist dann zumindest im wesentlichen durchsichtig, was in der Darstellung der Fig. 2 durch die strichlinierte Darstellung des Anzeigeelements 2 dargestellt ist. FIG. 2 shows a section of the mirror 1 when the temperature of the mirror surface is below the minimum temperature. The display element 2 is then at least essentially transparent, which is shown in the illustration in FIG. 2 by the dashed line illustration of the display element 2 .
Fig. 3 zeigt den Ausschnitt des Spiegels 1, wenn dessen Spiegelfläche eine Temperatur oberhalb der Mindesttemperatur aufweist. Fig. 3 shows the detail of the mirror 1 when its mirror surface has a temperature above the minimum temperature.
Anstelle des Umschlages von "zumindest im wesentlichen durchsichtig" (Fig. 2) auf "farbig bzw. dunkel" (Fig. 1, Fig. 3) kann auch ein Umschlag von der Darstellung des Anzeigeelements in einer ersten Farbe (Fig. 2) auf eine Darstellung des Anzeigeelements in einer zweiten Farbe (Fig. 1 und 3) erfolgen.Instead of changing the cover from "at least essentially transparent" ( FIG. 2) to "colored or dark" ( FIG. 1, FIG. 3), an envelope can also be used to display the display element in a first color ( FIG. 2) a representation of the display element in a second color ( Fig. 1 and 3).
