Abstract
Description
Die Erfindung betrifft ein Transformatorteil für ein Übertragungssystem zum Laden der Traktionsbatterien eines elektrisch angetriebenen Kraftfahrzeugs an einer Ladestation, die mindestens ein Transformatorteil aufweist, durch das elektrische Energie induktiv auf mindestens ein Transformatorteil am Kraftfahrzeug übertragen werden kann, wobei das fahrzeugseitige Transformatorteil und/oder das ladestationsseitige Transformatorteil eine elektrische Spulenanordnung aufweist, die von einem flexiblen Kunststoffmaterial umgeben ist.The invention relates to a transformer part for a transmission system for charging the traction batteries of an electrically driven motor vehicle to a charging station having at least one transformer part, can be transmitted inductively by the electrical energy to at least one transformer part on the motor vehicle, wherein the vehicle-side transformer part and / or the charging station side Transformer part has an electrical coil assembly which is surrounded by a flexible plastic material.
Durch das Zusammenführen des Transformatorteils eines Kraftfahrzeugs und eines Transformatorteil einer Ladestation ergänzen sich die Transformatorteile zu einem vollständigen Transformator, über den elektrische Energie von der Ladestation auf das Kraftfahrzeug zum Laden von Traktionsbatterien übertragen werden kann. Die flexible Ausgestaltung wenigstens eines der Transformatorteile stellt sicher, dass dieses eng an das andere Transformatorteil anfügbar ist, wodurch eine gute induktive Kopplung erzielt wird und Übertragungsverluste gering gehalten werden.By merging the transformer part of a motor vehicle and a transformer part of a charging station, the transformer parts complement each other to form a complete transformer via which electrical energy can be transmitted from the charging station to the motor vehicle for charging traction batteries. The flexible design of at least one of the transformer parts ensures that it is closely attachable to the other transformer part, whereby a good inductive coupling is achieved and transmission losses are kept low.
Ein derartiges Transformatorteil für ein Übertragungssystem ist in der nicht vorveröffentlichten Patentanmeldung
Vorraussetzung zur Erzielung einer effizienten induktiven Übertragung ist, dass die elektrisch bzw. magnetisch wirksamen Komponenten der Transformatorteile innerhalb der Umspritzung präzise positioniert sind. Hierzu müssen vor dem Umspritzen geeignete Mittel zum positionsgenauen Anordnen dieser Komponenten relativ zueinander vorgesehen werden, die aber nach dem Umspritzungsvorgang die Flexibilität des Transformatorteils möglichst wenig beeinträchtigen sollen. In der Patentanmeldung
Es stellte sich daher die Aufgabe, ein Transformatorteil zu schaffen, welches die vorgenannten Erfordernisse auf möglichst einfache und kostengünstige Weise erfüllt.It was therefore an object to provide a transformer part which meets the aforementioned requirements in the simplest and most cost-effective manner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Drahtwindungen der Spulenanordnung an einem biegsamen Halterahmen angeordnet sind.This object is achieved in that the wire windings of the coil assembly are arranged on a flexible support frame.
Erfindungsgemäß ist ein biegsamer Halterahmen vorgesehen, der die Drahtwindungen der Spulenanordnung haltert. Zusätzlich kann der Halterahmen auch zur Halterung von Ferritelementen dienen, die am Halterahmen in einer definierten Position zur Spulenanordnung vormontiert und durch den Umspritzungsvorgang in dieser Position fixiert werden.According to the invention, a flexible holding frame is provided, which holds the wire turns of the coil arrangement. In addition, the holding frame can also serve for holding ferrite elements, which are pre-assembled on the holding frame in a defined position to the coil assembly and fixed by the Umspritzungsvorgang in this position.
Die Möglichkeiten, die Spulenanordnung und vorzugsweise auch die Ferritelemente vor der Umspritzung an dem Halterahmen vorzumontieren, vereinfachen den Umspritzungsvorgang sowie allgemein die Montage des Transformatorteils.The possibilities of preassembling the coil arrangement and preferably also the ferrite elements before the encapsulation on the holding frame simplify the encapsulation process and in general the assembly of the transformer part.
Die flexiblen Eigenschaften des Transformatorteils werden durch den Halterahmen nicht beeinträchtigt, wenn dieser zumindest quer zu seiner Längserstreckung ausreichend biegsam ausgebildet ist. Eine ausreichende Biegsamkeit kann insbesondere dadurch erreicht werden, dass der Halterahmen aus mehreren Teilen besteht, die in der Längsrichtung des Haltrahmens etwa über schmale Verbindungsstege mechanisch nur schwach aneinander gekoppelt sind.The flexible properties of the transformer part are not affected by the support frame, if this is sufficiently flexible at least transversely to its longitudinal extent. A sufficient flexibility can be achieved in particular by the fact that the holding frame consists of several parts, which are mechanically weakly coupled to each other in the longitudinal direction of the holding frame approximately via narrow connecting webs.
Der Halterahmen kann beispielsweise als eine einstückig geformte Platte ausgebildet sein, die durch freigestanzte Ausnehmungen in mehrere gegeneinander biegsame Abschnitte unterteilt ist.The holding frame may for example be formed as an integrally formed plate which is divided by punched-out recesses into a plurality of mutually flexible sections.
Besonders vorteilhaft ist, wenn der Halterahmen nicht einstückig geformt ist, sondern aus einer Anzahl von vorgefertigten Trägerteilen zusammengesetzt ist. Die Vorfertigung von beispielsweise spritzgegossenen Trägerteilen, die anschließend zu einem Halterahmen zusammengefügt werden, ermöglicht die Ausformung komplexerer Anordnungen, als sie bei einer einstückigen Herstellung des Halterahmens möglich sind.It is particularly advantageous if the support frame is not integrally formed, but is composed of a number of prefabricated support members. The prefabrication of, for example, injection-molded support parts, which are then assembled into a holding frame, allows the formation of more complex arrangements, as they are possible in a one-piece production of the holding frame.
Darüber hinaus ermöglicht bereits eine relativ geringe Anzahl unterschiedlicher Trägerteile den baukastenartigen Aufbau einer größeren Anzahl von Fertigungsvarianten eines Halterahmens.In addition, even a relatively small number of different carrier parts allows the modular construction of a larger number of production variants of a holding frame.
Vorteilhafte Einzelheiten eines erfindungsgemäßen Transformatorteils gehen aus der Zeichnung hervor, die nachfolgend erläutert werden soll. Es zeigen Advantageous details of a transformer part of the invention will become apparent from the drawing, which will be explained below. Show it
