Description

Die vorliegende Erfindung betrifft eine Ladekabelvorrichtung mit einem längenveränderlichen, elektrischen Ladekabel mit einem längsendseitig angeordneten Kontaktelement, beispielsweise einer Kupplung oder einem Stecker. Die Erfindung betrifft außerdem eine Ladestation oder ein Kraftfahrzeug, insbesondere ein Elektro- oder ein Hybridfahrzeug, jeweils mit einer derartigen Ladekabelvorrichtung.The present invention relates to a charging cable device with a variable-length, electrical charging cable with a longitudinal end arranged contact element, such as a clutch or a plug. The invention also relates to a charging station or a motor vehicle, in particular an electric or a hybrid vehicle, each with such a charging cable device.

Aus der DE 10 2009 024 632 A1 ist ein längenveränderliches, elektrisches Verbindungskabel mit zwei jeweils längsendseitig angeordneten Kontaktelementen, beispielsweise einer Kupplung und einem Stecker, bekannt, wobei zwischen den beiden Kontaktelementen ein längenveränderliches Tragelement in der Art einer Seele vorgesehen ist, an welchem ein spiralförmiger, elektrischer Leiter gehalten ist. Hierdurch soll ein längenveränderliches Verbindungskabel geschaffen werden, das in jeder gewünschten Länge mit einer maximal zulässigen Stromstärke belastet werden kann und das zugleich einfach Handzuhaben ist.From the DE 10 2009 024 632 A1 is a variable-length, electrical connection cable with two longitudinally arranged contact elements, such as a coupling and a plug, known, between the two contact elements a variable-length support member is provided in the manner of a soul, on which a spiral, electrical conductor is held. In this way, a variable-length connection cable is to be created, which can be loaded in any desired length with a maximum allowable amperage and which is also easy to handle.

Aufgrund des stetig steigenden Umweltbewusstseins rücken zunehmend Elektro- oder Hybridfahrzeuge in den Fokus des Interesses, wobei insbesondere reine Elektrofahrzeuge turnusmäßig an einer Ladestation aufgeladen werden müssen. Hierbei sorgt insbesondere das Auf- und Abwickeln der Ladekabel für Probleme, da beispielsweise aus dem Bereich von Staubsaugern bekannte Rollsysteme nicht einfach übernommen werden können, da bei den bei Elektrofahrzeugen zu übertragenden elektrischen Leistungen zu viel Energie und damit auch zu viel Wärme anfällt. Zudem müssten bei der Verwendung von aus dem Bereich der Staubsauger bekannten Rollsystemen Trommeln mit entsprechenden Schleifkontakten verwendet oder aber eine Verdrehung des Ladekabels in Kauf genommen werden.Due to the ever-increasing environmental awareness, electric or hybrid vehicles are increasingly becoming the focus of interest, with pure electric vehicles, in particular, having to be charged at regular intervals at a charging station. Here, in particular, the winding and unwinding of the charging cable for problems because, for example, from the field of vacuum cleaners known rolling systems can not be easily adopted, since in the case of electric vehicles to be transmitted electrical power too much energy and thus too much heat is obtained. In addition, when using rolling systems known from the field of vacuum cleaners, drums with corresponding sliding contacts would have to be used, or a twisting of the charging cable would have to be accepted.

Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine Ladevorrichtung eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine einfache und komfortable Handhabung auszeichnet.The present invention therefore deals with the problem of providing for a loading device an improved embodiment, which is characterized in particular by a simple and comfortable handling.

Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Ladekabelvorrichtung vorzusehen, die alternativ an einer stationären Ladestation oder an einem Fahrzeug, insbesondere an einem Hybrid- oder Elektrofahrzeug, angeordnet wird und die ein längenveränderliches, elektrische Ladekabel mit einem längsendseitig angeordneten Kontaktelement aufweist. Dieses Kontaktelement ist beispielsweise in der Art einer Kupplung oder eines Steckers ausgebildet, wobei das Ladekabel an sich eine seilartige Seele und einen diese Seele spiralförmig umgebenden elektrischen Leiter aufweist. Einenends ist dabei die Seele mit dem Kontaktelement fest verbunden, wogegen sie andererseits mit einer Wickelvorrichtung zum Auf-/Abwickeln der Seele verbunden ist. Erfindungsgemäß ist nun am Kontaktelement, das heißt beispielsweise am Stecker oder an der Kupplung, ein Bedienelement zum Aktivieren der Wickelvorrichtung angeordnet, was die Handhabung des Ladekabels erheblich erleichtert, da insbesondere das Auf- und Abwickeln des Ladekabels mit der erfindungsgemäßen Ladekabelvorrichtung deutlich vereinfacht wird. Durch den spiralförmig ausgebildeten elektrischen Leiter ist darüber hinaus die Übertragung der maximal möglichen elektrischen Energie auch bei lediglich teilweise ausgezogenem Ladekabel möglich, da aufgrund der vergleichsweise großen Oberfläche des spiralförmig gerollten elektrischen Leiters dieser gut kühlbar ist. Zudem werden bei der erfindungsgemäßen Ladekabelvorrichtung keine Schleifkontakte benötigt, wie diese beispielsweise bei auf Trommeln aufgewickelten elektrischen Leitern erforderlich wären. Über das Bedienelement am Kontaktelement kann auf denkbar einfach Weise die Wickelvorrichtung aktiviert, beispielsweise eine vorgespannte Feder gelöst oder eine Antriebseinrichtung eingeschaltet werden, wodurch sich insbesondere das Aufwickeln des Ladekabels angenehm einfach gestaltet.The present invention is based on the general idea to provide a charging cable device, which is alternatively arranged on a stationary charging station or on a vehicle, in particular on a hybrid or electric vehicle, and which has a variable-length, electrical charging cable with a longitudinally arranged contact element. This contact element is formed, for example, in the manner of a coupling or a plug, wherein the charging cable per se has a cable-like soul and a spiral surrounding this soul electrical conductor. At one end, the soul is firmly connected to the contact element, whereas on the other hand, it is connected to a winding device for winding / unwinding of the soul. According to the invention, an operating element for activating the winding device is now arranged on the contact element, that is, for example, on the plug or on the coupling, which considerably facilitates the handling of the charging cable, since in particular the winding and unwinding of the charging cable with the charging cable device according to the invention is significantly simplified. Due to the spiral-shaped electrical conductor, moreover, the transmission of the maximum possible electrical energy is possible even when the charging cable is only partially extended, since due to the comparatively large surface area of the spirally wound electrical conductor, it can be cooled well. In addition, no sliding contacts are required in the charging cable device according to the invention, as would be required, for example, when wound on drums electrical conductors. About the control element on the contact element can be activated in a very simple way, the winding device, for example, released a preloaded spring or a drive means are turned on, which in particular makes the winding of the charging cable pleasantly simple.

Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung ist ein rohrförmiger Aufnahmebehälter zum Aufbewahren des eingezogenen elektrischen Leiters vorgesehen, der zu dem belüftet oder mittels einer Kühleinrichtung aktiv kühlbar ist. Besonders bei teilweise eingezogenem und in dem Aufnahmebehälter aufgewickelten elektrischen Leiter kann es aufgrund einer hohen elektrischen Ladeleistung zu einer Erwärmung und gegebenenfalls auch zu einer Überhitzung und damit zu einer Beschädigung des elektrischen Ladekabels kommen. Aus diesem Grund ist der erfindungsgemäße Aufnahmebehälter mittels entsprechender Öffnung zwangsbelüftet oder aber mittels einer separaten Kühleinrichtung aktiv kühlbar, wodurch eine zu starke Erwärmung und insbesondere auch eine Beschädigung durch eine Überhitzung vermieden werden können. Durch die aktive Kühlung des Aufnahmebehälters kann zu dem auch ein Innenwiderstand des Ladekabels reduziert und damit eine erleichterte da widerstandsärmere, Übertragung elektrischer Energie erreicht werden.In an advantageous development of the solution according to the invention a tubular receptacle for storing the retracted electrical conductor is provided, which is ventilated to the active or by means of a cooling device actively cooled. Especially with partially retracted and wound up in the receptacle electrical conductor may be due to a high electrical charging power to a warming and possibly also to overheating and thus damage to the electrical charging cable. For this reason, the receptacle according to the invention is positively ventilated by means of a corresponding opening or can be actively cooled by means of a separate cooling device, as a result of which overheating and, in particular, damage due to overheating can be avoided. Due to the active cooling of the receptacle can also be reduced to an internal resistance of the charging cable and thus a facilitated as low-resistance, transmission of electrical energy can be achieved.

Zweckmäßig weist die Wickelvorrichtung eine Antriebseinrichtung, insbesondere einen Motor oder eine Feder, zum Auf-/Abwickeln der Seele auf, wobei die Antriebseinrichtung über das Bedienelement aktivierbar ist. Die Wickelvorrichtung kann dabei insbesondere federbeaufschlagt sein, so dass zum Verlängern des erfindungsgemäßen Ladekabels eine Zugkraft aufgebracht werden muss, ein Einziehen des Ladekabels jedoch von der die Wickelvorrichtung beaufschlagenden Feder bewirkt wird. Eine derartige Wicke Wickelvorrichtung kann mit vergleichsweise geringem Bauraumbedarf in der Ladekabelvorrichtung realisiert werden, wobei die Wickelvorrichtung selbstverständlich auch eine Sperreinrichtung aufweisen kann, welche die Wickelvorrichtung in einer beliebigen Stellung sperrt und dadurch eine definierte Länge des elektrischen Ladekabels vorgibt. Eine derartige Sperreinrichtung kann beispielsweise in der Art einer Ratsche ausgebildet sein, welche über eine ergonomisch günstig am jeweiligen Kontaktelement angeordnete Betätigung, beispielsweise auch über das Bedienelement, gelöst bzw. gesperrt werden kann.Expediently, the winding device has a drive device, in particular a motor or a spring, for winding / unwinding the core, wherein the drive device can be activated via the operating element. The winding device can thereby Be particularly spring-loaded, so that to extend the charging cable according to the invention, a tensile force must be applied, however, a retraction of the charging cable is effected by the spring acting on the winding device. Such a winding winding device can be realized with comparatively small space requirement in the charging cable device, wherein the winding device can of course also have a locking device which locks the winding device in any position and thereby predefines a defined length of the electric charging cable. Such a locking device can be designed, for example, in the manner of a ratchet, which can be released or locked via an ergonomically arranged on the respective contact element operation, for example, via the control element.

Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden in der nachfolgenden Beschreibung näher erläutert, wobei sich gleiche Bezugszeichen auf gleiche oder ähnliche oder funktional gleiche Bauteile beziehen.Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.

2 eine Darstellung wie in 1, jedoch mit ausgezogenem Ladekabel. 2 a representation like in 1 , but with extended charging cable.

Entsprechend den 1 und 2, weist eine erfindungsgemäße Ladekabelvorrichtung 1, die beispielsweise an einer Ladestation oder einem Fahrzeug, insbesondere an einem Elektro- oder Hybridfahrzeug, angeordnet sein kann, ein elektrisches Ladekabel 2 mit einem längsendseitig daran angeordneten Kontaktelement 3, beispielsweise einer Kupplung oder einem Stecker, auf. Das Ladekabel 2 besitzt eine seilartige Seele 4 sowie einen diese Seele 4 spiralförmig umgebenden, elektrischen Leiter 5, wobei die Seele 4 einenends mit einer Wickelvorrichtung 6 zum Auf-/Abwickeln und anderenends mit dem Kontaktelement 3 verbunden ist. Die Wickelvorrichtung 6 weist eine Antriebseinrichtung, insbesondere einen Motor 7 oder eine Feder 8 vor allem zum Aufwickeln der Seele 4 auf, wobei die Antriebseinrichtung, das heißt der Motor 7 oder die Feder 8 über ein am Kontaktelement 3 angeordnetes Bedienelement 9 aktivierbar ist. Die Antriebseinrichtung kann dabei ausschließlich das Aufwickeln bzw. Einziehen des Ladekabels 2 bzw. der Seele 4 bewirken, oder aber auch sowohl das Auf- als auch das Abwickeln unterstützen.According to the 1 and 2 has a charging cable device according to the invention 1 , which may be arranged for example on a charging station or a vehicle, in particular on an electric or hybrid vehicle, an electric charging cable 2 with a longitudinal end disposed thereon contact element 3 , For example, a clutch or a plug on. The charging cable 2 has a rope-like soul 4 as well as this soul 4 spirally surrounding electrical conductor 5 , being the soul 4 at one end with a winding device 6 for winding / unwinding and at the other end with the contact element 3 connected is. The winding device 6 has a drive device, in particular a motor 7 or a spring 8th especially for winding up the soul 4 on, wherein the drive means, that is, the engine 7 or the spring 8th via a contact element 3 arranged operating element 9 is activatable. The drive device can only the winding or retraction of the charging cable 2 or the soul 4 or support both the up and the unwinding.

Betrachtet man die 1 und 2 weiter, so kann man erkennen, dass ein rohrförmiger Aufnahmebehälter 10 zum Aufbewahren des eingezogenen elektrischen Leiters 5 vorgesehen ist, wobei der rohrförmige Aufnahmebehälter 10 belüftet oder sogar mittels einer separaten Kühleinrichtung aktiv gekühlt ist. Hierdurch wird eine übermäßige Erwärmung des elektrischen Leiters 5 und damit eine Beschädigung desselben im zumindest teilweise eingezogenen Zustand während des Ladens, bei welchem üblicherweise hohe Ladeströme fließen, vermieden.Looking at the 1 and 2 Further, it can be seen that a tubular receptacle 10 for storing the retracted electrical conductor 5 is provided, wherein the tubular receptacle 10 ventilated or even actively cooled by a separate cooling device. This will cause excessive heating of the electrical conductor 5 and thus damage thereof in at least partially retracted state during charging, in which usually high charging currents flow, avoided.

Zusätzlich kann an der Ladekabelvorrichtung 1 eine Aufnahme 11 vorgesehen sein, in welche das Kontaktelement 3 in dessen nicht Gebrauchszustand eingesteckt bzw. eingeschoben werden kann. Neben der Antriebseinrichtung, das heißt insbesondere neben dem Motor 7 bzw. der Feder 8, kann die Wickelvorrichtung 6 zusätzlich eine in der Art einer Ratsche ausgebildete Sperreinrichtung 12 aufweisen, die vorzugsweise ebenfalls über das Kontaktelement 3 angeordnete Bedienelement 9 betätigt, das heißt insbesondere gelöst werden kann. Generell kann die Ladekabelvorrichtung 1 wie eingangs erwähnt an einer stationären Ladestation oder an einem Kraftfahrzeug, insbesondere an einem Elektrofahrzeug oder an einem Hybridfahrzeug, angeordnet sein.In addition, on the charging cable device 1 a recording 11 be provided, in which the contact element 3 can be inserted or inserted in its non-use state. In addition to the drive device, that is, in particular, next to the engine 7 or the spring 8th , the winding device can 6 additionally formed in the manner of a ratchet locking device 12 preferably also via the contact element 3 arranged operating element 9 operated, that is, in particular, can be solved. In general, the charging cable device 1 as mentioned above, be arranged on a stationary charging station or on a motor vehicle, in particular on an electric vehicle or on a hybrid vehicle.

Durch die erfindungsgemäße Ausbildung des Ladekabels 2 und insbesondere des spiralartig geformten elektrischen Leiters 5, kann das Ladekabel 2 leicht ausgezogen werden und erzeugt auch bei größeren zu überbrückenden Strecken keine erhöhte Zugbelastung auf das Kontaktelement 3, da die Zugbelastung einzig und allein über die Seele 4, beispielsweise ein Stahlseil, übertragen wird. Der Einzug des Ladekabels 2 kann über die Antriebseinrichtung, das heißt beispielsweise über den (Elektro-)Motor 7 oder die Feder 8 erfolgen, wobei die Betätigung der Antriebseinrichtung über das am Kontaktelement 3 angeordnete Bedienelement 9 bewirkt wird. Der spiralförmig ausgebildete Leiter 5 kann in seinem Nichtgebrauchszustand in den rohrförmigen Aufnahmebehälter 10 eingezogen werden, der mit einer ausreichenden Belüftung, insbesondere auch mit einer aktiven Kühlung, wie beispielsweise einem Gebläse oder einer Kühlung der Außenwand, versehen ist.Due to the inventive design of the charging cable 2 and in particular the spiral-shaped electrical conductor 5 , can the charging cable 2 be pulled out easily and generates no increased tensile load on the contact element, even with larger distances to be bridged 3 because the tensile load is solely on the soul 4 , For example, a steel wire is transmitted. The feeder of the charging cable 2 can via the drive device, that is, for example, via the (electric) motor 7 or the spring 8th take place, wherein the actuation of the drive means via the on the contact element 3 arranged operating element 9 is effected. The spirally formed conductor 5 can in its non-use state in the tubular receptacle 10 be drawn, which is provided with a sufficient ventilation, in particular with an active cooling, such as a fan or a cooling of the outer wall.

Die Vorteile des erfindungsgemäßen Ladekabels 2 liegen insbesondere in dem reduzierten Wärmestau, da auf Grund der spiralförmigen Ausbildung des elektrischen Leiters 5 dieser durch die Umgebungsluft gut gekühlt werden kann. Zu dem benötigt die erfindungsgemäße Ladekabelvorrichtung 1 keine Schleifkontakte, wie diese bei einer bislang bekannten Trommelwicklung erforderlich wären.The advantages of the charging cable according to the invention 2 are in particular in the reduced heat accumulation, since due to the spiral-shaped design of the electrical conductor 5 this through the Ambient air can be cooled well. For that requires the charging cable device according to the invention 1 no sliding contacts, as would be required in a previously known drum winding.
