Description
Die Erfindung betrifft ein Kraftwagenbauteil mit zumindest einem Abschirmelement nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren zu dessen Herstellung nach dem Oberbegriff von Patentanspruch 3.The invention relates to a motor vehicle component with at least one shielding element according to the preamble of patent claim 1 and to a method for the production thereof according to the preamble of patent claim 3.
Aus der
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde ein Kraftwagenbauteil nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren zu dessen Herstellung nach dem Oberbegriff von Patentanspruch 3 so weiter zu entwickeln, dass eine verbesserte Integration eines Abschirmelementes in Kraftwagenbauteile ermöglicht wird.The present invention is therefore the object of a motor vehicle component according to the preamble of claim 1 and a method for its production according to the preamble of claim 3 further develop so that improved integration of a shielding in automotive components is possible.
Diese Aufgabe wird durch ein Kraftwagenbauteil mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren zum Herstellen eines Kraftwagenbauteils mit den Merkmalen des Patentanspruchs 3 gelöst.This object is achieved by a motor vehicle component having the features of patent claim 1 and by a method for producing a motor vehicle component having the features of patent claim 3.
Ein solches Kraftwagenbauteil weist wenigstens ein Abschirmelement zur Abschirmung elektrischer, magnetischer und/oder elektromagnetischer Felder auf. Erfindungsgemäß ist vorgesehen, dass das wenigstens eine Abschirmelement als mikrostrukturierte Oberflächenstruktur des Bauteils ausgebildet ist, welche aus einzelnen Pixeln aus einem leitfähigen und/oder magnetischen und/oder magnetierbaren Material aufgebaut ist. Mit anderen Worten ist das Abschirmelement direkt in das Bauteil integriert, so dass dessen abschirmende Strukturen nicht in Form einer Folie oder dergleichen bereitgestellt werden müssen. Durch die Integration direkt in das Kraftwagenbauteil wird eine besonders belastbare abschirmende Struktur geschaffen, die auch den Belastungen im Betrieb des Kraftwagens stand zu halten vermag. Durch das Aufbringen in Form einzelner Pixel ist eine besonders flexible Fertigung solcher Kraftwagenbauteile möglich. Anordnung und Verlauf von abschirmenden Strukturen des Abschirmelementes können durch eine derartige Technik problemlos an unterschiedliche Formen des Kraftwagenbauteils oder unterschiedliche Anordnungen von Abschirmelementen angepasst werden.Such a motor vehicle component has at least one shielding element for shielding electrical, magnetic and / or electromagnetic fields. According to the invention, it is provided that the at least one shielding element is designed as a microstructured surface structure of the component, which is constructed from individual pixels made of a conductive and / or magnetic and / or magnetizable material. In other words, the shielding element is integrated directly into the component, so that its shielding structures need not be provided in the form of a foil or the like. By integrating directly into the motor vehicle component, a particularly resilient shielding structure is created, which is also able to withstand the stresses during operation of the motor vehicle. By applying in the form of individual pixels, a particularly flexible production of such motor vehicle components is possible. Arrangement and course of shielding structures of the shielding element can be easily adapted by such a technique to different shapes of the motor vehicle component or different arrangements of shielding.
Geeignete abschirmende Strukturen sind vorzugsweise allseitig geschlossene (Faraday-)Käfige, z. B. in Form von Blechen, Folien, Gittern oder Netzen. Geeignete Materialien zur elektrischen oder elektromagnetischen Abschirmung sind leitfähig, z. B. metallisch. Für transparente Bauteile ist auch eine transparente Abschirmung vorteilhaft. Dazu eignen sich z. B. TCOs (transparent Conductive Oxide), insbesondere ITO (Indium Tin Oxide). Geeignete Materialien magnetischen Abschirmung sind magnetisch, insbesondere ferromagnetisch mit hoher Permeabilität und geringer Remanenz, oder entsprechend magnetisierbar. Hierzu besonders geeignet ist das sogenannte Mumetall, eine weichmagnetische Nickel-Eisen-Legierung (ca. 75–80% Nickel) hoher magnetischer Permeabilität.Suitable shielding structures are preferably closed on all sides (Faraday) cages, z. B. in the form of sheets, foils, grids or nets. Suitable materials for electrical or electromagnetic shielding are conductive, z. B. metallic. For transparent components, a transparent shield is also advantageous. These are z. As TCOs (transparent Conductive Oxide), in particular ITO (indium tin oxides). Suitable materials magnetic shielding are magnetic, in particular ferromagnetic with high permeability and low remanence, or magnetizable accordingly. Particularly suitable for this purpose is the so-called Mumetall, a soft magnetic nickel-iron alloy (about 75-80% nickel) of high magnetic permeability.
Bevorzugt überlappt jedes Pixel einer abschirmenden Struktur mit wenigstens einem benachbarten Pixel. Hierdurch können beliebige lineare oder flächige abschirmende Strukturen geschaffen werden.Preferably, each pixel overlaps a screening structure with at least one adjacent pixel. As a result, any desired linear or planar shielding structures can be created.
Die Erfindung betrifft weiterhin ein Verfahren zum Herstellen eines Kraftwagenbauteils mit zumindest einem Abschirmelement zur Abschirmung elektrischer, magnetischer und/oder elektromagnetischer Felder. Bei einem erfindungsgemäßen Verfahren wird wenigstens Abschirmelement mittels eines Druckverfahrens in Form einzelner Pixel aus einem leitfähigen und/oder magnetischen und/oder magnetierbaren Material auf eine Oberfläche des Bauteils aufgedruckt. Diese sogenannte Pixeltechnik wird z. B. in der
Als Druckverfahren zum Aufdrucken der einzelnen Pixel können druckformbasierte Verfahren, wie zum Beispiel Siebdruck, Trommeldruck oder Tampondruck verwendet werden. Alternativ sind auch druckkopfbasierte Verfahren einsetzbar. Hierbei kann es sich um druckkopfbasierte Verfahren mit kontinuierlichem Tropfenstrom oder mit diskontinuierlichen Tropfenstrom handeln, bei welchem die Einzeltropfen mechanisch oder thermisch erzeugt werden. Gerade mit solchen druckkopfbasierten Verfahren ist eine besonders flexible Gestaltung einer abschirmenden Struktur auch auf komplex geformten Kraftwagenbauteilen möglich, da der Druckkopf bei einem solchen Verfahren in beliebigen Raumkurven geführt werden kann. Dies kann besonders vorteilhaft mit einem Druckkopf erfolgen wie er in der
In weiterer Ausgestaltung der Erfindung wird das Kraftwagenbauteil nach dem Aufdrucken des zumindest einen Abschirmelementes einer thermischen Nachbehandlung unterzogen, bei welcher das Material der Pixel wenigstens teilweise aufgeschmolzen und/oder ausgehärtet wird. Durch ein teilweises Aufschmelzen der Pixel kann deren Überlappung verbessert werden, so dass der Innenwiderstand einer derart erzeugten abschirmenden Struktur besonders niedrig ist. Durch das Aushärten des Materials der Pixel werden besonders haltbare abschirmende Strukturen geschaffen.In a further embodiment of the invention, the motor vehicle component is subjected after the printing of at least one shielding element of a thermal aftertreatment, in which the material of the pixels is at least partially melted and / or cured. By a partial melting of the pixels, their overlap can be improved, so that the internal resistance of a shielding structure produced in this way is particularly low. By curing the material of the pixels, particularly durable shielding structures are created.
Alternativ oder additiv kann im Bedarfsfall die Haftung der Pixeln auf der Bauteiloberfläche verbessert werden, z. B. mittels einer Plasmaaktivierung der Bauteiloberfläche.Alternatively or additionally, the adhesion of the pixels on the component surface can be improved if necessary, for. B. by means of a plasma activation of the component surface.
In bevorzugter Ausgestaltung des erfindungsgemäßen Verfahrens wird abschließend noch eine Schutzschicht aufgebracht. Dies kann ebenfalls drucktechnisch erfolgen, aber z. B. auch durch Bedampfen oder Tauchen. Geeignete Schichten bestehen z. B. aus handelsüblichem Klarlack.In a preferred embodiment of the method according to the invention, finally, a protective layer is applied. This can also be done by printing, but z. B. also by steaming or dipping. Suitable layers consist for. B. from commercial clearcoat.
Im Folgenden soll die Erfindung und ihre Ausführungsformen anhand der Zeichnung näher erläutert werden. Hierbei zeigen:In the following, the invention and its embodiments will be explained in more detail with reference to the drawing. Hereby show:
