Anzeigevorrichtung.  Display device.
Die vorliegende Erfindung betrifft eine Anzeigevorrichtung eines Kraftfahrzeuges mit einem Display mit einer Sichtseite, das eine Skala aufweist und einem motorisch angetriebenen Zeiger. The present invention relates to a display device of a motor vehicle with a display with a visible side, which has a scale and a motor-driven pointer.
Derartige Anzeigevorrichtungen sind aus dem Stand der Technik hinlänglich bekannt. Bei diesen Anzeigevorrichtungen ist hinter dem Display ein Motor angeordnet, der einen Zeiger, der sich auf der Sichtseite des Displays befindet, antreibt. Zwischen dem Motor und dem Zeiger ist eine Welle angeordnet, die durch ein Loch in dem Display geführt wird. Eine derartige Anzeigevorrichtung ist jedoch für Thin Film Transistor-Displays (TFT-Display) nicht geeignet. Such display devices are well known in the art. In these display devices behind the display, a motor is arranged, which drives a pointer, which is located on the visible side of the display. Between the motor and the pointer, a shaft is arranged, which is passed through a hole in the display. However, such a display device is not suitable for thin film transistor displays (TFT display).
Es war deshalb die Aufgabe der vorliegenden Erfindung eine Anzeigevorrichtung zur Verfügung zu stellen, bei der das Display ein TFT-Display sein kann. It was therefore the object of the present invention to provide a display device in which the display can be a TFT display.
Gelöst wird die Aufgabe mit einer Anzeigevorrichtung eines Kraftfahrzeuges mit einem Display mit einer Sichtseite, das eine Skala aufweist und mit einem motorisch angetriebenen Zeiger, wobei der Motor, der den Zeiger antreibt auf der Sichtseite des Displays vorgesehen «st. The object is achieved with a display device of a motor vehicle with a display with a visible side, which has a scale and with a motor-driven pointer, wherein the motor that drives the pointer provided on the visible side of the display «st.
Die vorliegende Erfindung betrifft die Anzeigevorrichtung eines Kraftfahrzeuges. Derartige Anzeigevorrichtungen zeigen beispielsweise die Geschwindigkeit des Fahrzeuges, die Drehzahl des Motors, die Temperatur des Kühlwassers und/oder den Füllstand des Tanks an. The present invention relates to the display device of a motor vehicle. Such display devices indicate, for example, the speed of the vehicle, the speed of the engine, the temperature of the cooling water and / or the level of the tank.
Derartige Anzeigevorrichtungen haben ein Display, das eine Rück- und eine Sichtseite aufweist, wobei die Sichtseite die dem Fahrgastraum zugewandte Seite ist. Auf diesem Display ist beispielsweise eine Skala angeordnet, die zusammen mit dem beweglich vorgesehenen Zeiger den jeweils darzustellenden Wert anzeigt. Such display devices have a display which has a rear and a visible side, wherein the visible side is the side facing the passenger compartment. On this display, for example, a scale is arranged, which displays the value to be displayed together with the pointer provided for movement.
Gemäß der vorliegenden Erfindung wird dieser Zeiger motorisch insbesondere mit einem Elektromotor ganz besonders bevorzugt mit einem Piezomotor, wie er beispielsweise aus According to the present invention, this pointer is motorized, in particular with an electric motor very particularly preferably with a piezoelectric motor, as he, for example
BESTÄTIGUNGSKOPIE der US 7,075,212D4 bekannt ist, angetrieben. Vorzugsweise treibt der Motor den Zeiger linear und/oder rotatorisch an. CONFIRMATION COPY US 7,075,212D4 is known driven. Preferably, the motor drives the pointer linearly and / or rotationally.
Gemäß der vorliegenden Erfindung ist dieser Motor auf der Sichtseite des Displays und damit auf derselben Seite wie der Zeiger vorgesehen. Dadurch muss kein Loch in das Display zur Durchführung einer Welle eingebracht werden, so dass beispielsweise TFT- Displays als Display geeignet sind. According to the present invention, this motor is provided on the visible side of the display and thus on the same side as the pointer. As a result, no hole must be introduced into the display for performing a wave, so that, for example, TFT displays are suitable as a display.
Vorzugsweise weist der Zeiger eine Zeigerkappe auf, die sich vorzugsweise in seiner Rotationsachse befindet. Besonders bevorzugt ist der Motor in und/oder unter dieser Zeigerkappe angeordnet und somit für den Fahrzeuginsassen nicht oder nur schwer sichtbar. Preferably, the pointer has a pointer cap, which is preferably located in its axis of rotation. Particularly preferably, the motor is arranged in and / or under this pointer cap and thus not or hardly visible to the vehicle occupants.
Vorzugsweise erfolgt die Versorgung des Motors mit elektrischer Energie mittels einer leitfähigen, ganz bevorzugt durchsichtigen Folie. Diese Folie wird ganz besonders bevorzugt an dem Display, noch mehr bevorzugt auf der Sichtseite des Displays angeordnet. Besonders bevorzugt wird die leitfähige Folie auf dem Display aufgeklebt, aufgesiegelt oder sie stellt eine Schicht des Displays dar. Die elektrische Energie kann auch zur Beleuchtung des Zeigers eingesetzt werden. Preferably, the supply of the motor with electrical energy by means of a conductive, very preferably transparent film. This film is most preferably arranged on the display, more preferably on the visible side of the display. Particularly preferably, the conductive film is glued on the display, sealed or it represents a layer of the display. The electrical energy can also be used to illuminate the pointer.
Im Folgenden wird die Erfindung anhand der Figuren 1 und 2 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein. The invention is explained below with reference to FIGS. 1 and 2. These explanations are merely exemplary and do not limit the general inventive concept.
Figur 1 zeigt die erfindungsgemäße Anzeigevorrichtung. FIG. 1 shows the display device according to the invention.
Figur 2 zeigt einen für die erfindungsgemäße Anzeigevorrichtung einsetzbaren Motor. Figure 2 shows a usable for the display device according to the invention engine.
Figur 1 zeigt die erfindungsgemäße Anzeigevorrichtung 1 , die ein Display 2 mit einer Skala 3 aufweist. Auf der Sichtseite d.h. auf der dem Fahrgastraum zugewandten Seite des Displays weist die erfindungsgemäße Anzeigevorrichtung einen Zeiger 4 mit einer Zeigerkappe 6 auf, die in seiner Rotationsachse angeordnet ist. In und/oder unter dieser Zeigerkappe jedoch ebenfalls vor der Sichtseite des Displays ist ein Motor, wie er beispielsweise in Figur 2 dargestellt ist, vorgesehen, der den Zeiger 6 rotatorisch antreibt. Die elektrische Energieversorgung dieses Motors erfolgt über eine durchsichtige leitfähige Folie, die ebenfalls auf der Sichtseite des Displays vorgesehen ist. Der jeweils anzuzeigende Wert ergibt sich durch die jeweilige Winkelstellung des Zeigers 4 relativ zu der Skala 3. Figur 2 zeigt einen Motor 5 der zum Antrieb des Zeigers 4 der erfindungsgemäßen Vorrichtung eingesetzt werden kann. Bei diesem Motor handelt es sich um einen Piezomotor, der eine Piezokeramik 9 aufweist, die unter Anlage von elektrischer Wechselspannung Schwingungen erzeugt, die mittels Schwingelementen 8, hier Sicheln, verstärkt werden und die unter Reibschluss ein Antriebsteil 7, hier einen Ring, rotatorisch antreiben. Dieser Ring 7 kann Teil der Kappe 6 sein oder mit dieser oder dem Zeiger 4 verbunden sein. FIG. 1 shows the display device 1 according to the invention, which has a display 2 with a scale 3. On the visible side ie on the passenger compartment side facing the display, the display device according to the invention has a pointer 4 with a pointer cap 6, which is arranged in its axis of rotation. In and / or under this pointer cap but also in front of the visible side of the display, a motor, as shown for example in Figure 2, is provided which rotates the pointer 6 rotates. The electrical power supply of this engine via a transparent conductive film, which is also provided on the visible side of the display. The respective value to be displayed results from the respective angular position of the pointer 4 relative to the scale 3. Figure 2 shows a motor 5 which can be used to drive the pointer 4 of the device according to the invention. This motor is a piezomotor, which has a piezoceramic 9, which generates oscillations under the application of electrical alternating voltage, which are amplified by means of oscillating elements 8, in this case sickles, and which, under friction, drive a drive part 7, here a ring, rotatory. This ring 7 may be part of the cap 6 or connected to this or the pointer 4.
