Description
Die Erfindung betrifft ein Kraftfahrzeug, umfassend einen Energiespeicher, der über ein fahrzeugseitig fest installiertes Ladekabel mit einem Anschlussstecker, das zum Verbinden mit einer externen Stromquelle aus seiner Aufbewahrungsstellung aus dem Fahrzeug herausziehbar ist, aufladbar ist.The invention relates to a motor vehicle, comprising an energy store which can be recharged via a permanently installed charging cable on the vehicle side with a connection plug which can be pulled out of its storage position for connection to an external power source.
Kraftfahrzeuge mit Elektroantrieb werden in Zukunft einen immer größeren Marktanteil einnehmen, einerseits aus Gründen des Umweltschutzes, andererseits aufgrund niedrigerer Betriebskosten. Diese Elektrofahrzeuge umfassen üblicherweise einen Energiespeicher, also einen hinreichend leistungsfähigen Akkumulator, der über ein Ladekabel, das über einen entsprechenden Anschlussstecker verfügt, mit einer externen Stromquelle aufgeladen werden kann. Eine solche Stromquelle kann beispielsweise an einer üblichen Tankstelle vorgesehen sein, es kann sich aber auch um eine sonstige öffentliche oder private Streckdose handeln.Automotive electric vehicles will take an increasing market share in the future, on the one hand for reasons of environmental protection, on the other hand due to lower operating costs. These electric vehicles usually include an energy storage, that is, a sufficiently powerful accumulator, which can be charged via a charging cable, which has a corresponding connector, with an external power source. Such a power source may for example be provided at a conventional gas station, but it may also be another public or private draw box.
Neben einem losen Ladekabel, das im Fahrzeug mitgeführt wird, und das zwei Anschlussstecker aufweist, nämlich einen ersten zum Anstecken an der externen Stromquelle, und einen zweiten zum Anstecken an einem geeigneten Ladeanschlussstecker am Fahrzeug, ist es auch bekannt, eine integrierte Ladeanschlusseinrichtung am Fahrzeug vorzusehen, bei der das Ladekabel fahrzeugseitig fest Installiert ist, mithin also dauerhaft in elektrischer Verbindung zum Energiespeicher steht. Eine solche Ladeanschlusseinrichtung und damit ein Kraftfahrzeug mit einer solchen Ladeanschlusseinrichtung ist beispielsweise aus
Eine solche Ladeanschlussvorrichtung mit auf einer Kabelrolle aufgewickeltem Ladekabel lässt jedoch üblicherweise nur die Verwendung eines Kabels mit relativ geringem Leiterquerschnitt zu. Denn zum einen muss das Kabel insbesondere im Bereich seines unmittelbar rollenseitig vorgesehenen Ende mit sehr geringem Wickelradius aufgewickelt werden, es muss also eine beachtliche Flexibilität besitzen. Zum anderen würde bei einem Ladekabel mit einer Länge von üblicherweise mehreren Metern bei einem relativ dicken Leiter- und damit Kabelquerschnitt das Kabel einen insgesamt großen Wickeldurchmesser besitzen, wenn es in mehreren Lagen übereinander aufgewickelt wird, respektive würde, wenn es nur in einer Wickelebene aufgewickelt wird, einen beachtlichem Bauraum in Richtung der Wickelachse einnehmen. Ein solcher ist jedoch in diesem Bereich, wo diese Ladeanschlusseinrichtung verbaut wird, häufig nicht gegeben. Da jedoch ein möglichst großer Leitungsquerschnitt für einen möglichst schnellen und effizienten Ladevorgang wünschenswert ist, besteht allgemein der Wunsch nach Verwendung möglichst dicker Ladekabel.However, such a charging connection device with a cable reel wound on a cable usually allows only the use of a cable with a relatively small conductor cross-section. For one thing, the cable has to be wound up in the region of its end, which is provided directly on the roller side, with a very small winding radius, so it must have considerable flexibility. On the other hand, in a charging cable with a length of usually several meters with a relatively thick conductor and thus cable cross-section, the cable would have a total large winding diameter when it is wound in several layers one above the other, respectively, if it is wound only in a winding plane , take a considerable space in the direction of the winding axis. However, such is often not given in this area where this charging terminal device is installed. However, since the largest possible cable cross-section for a fast and efficient charging is desirable, there is a general desire to use the largest possible charging cable.
Der Erfindung liegt damit das Problem zugrunde, ein Kraftfahrzeug anzugeben, das demgegenüber verbessert ist und die Verwendung eines Ladekabels mit einem großen Leiterquerschnitt ermöglicht.The invention is therefore based on the problem to provide a motor vehicle, which in contrast is improved and allows the use of a charging cable with a large conductor cross-section.
Zur Lösung dieses Problems ist bei einem Kraftfahrzeug der eingangs genannten Art erfindungsgemäß vorgesehen, dass das Ladekabel aus einem Kabelspeicher, in dem es vom festen Installationspunkt längs einer im Wesentlichen geraden Strecke zu einem Umlenkpunkt geführt, anschließend wenigstens einmal um einen Winkel zwischen 90°–180° umgelenkt und längs einer weiteren im Wesentlichen geraden Strecke zum Anschlussstecker geführt ist, gegen eine Rückstellkraft aus seiner Aufbewahrungsstellung herausziehbar ist.To solve this problem is provided according to the invention in a motor vehicle of the type mentioned that the charging cable from a cable storage in which it led from the fixed installation point along a substantially straight line to a deflection, then at least once by an angle between 90 ° -180 ° deflected and guided along a further substantially straight line to the connector, against a restoring force from its storage position can be pulled out.
Bei dem erfindungsgemäßen Kraftfahrzeug ist das Kabel in dem Kabelspeicher eingelegt, d. h., es läuft im Kabelspeicher im Wesentlichen geradlinig und ist ein- oder mehrfach umgelenkt. Bevorzugt wird es hierbei um ca. 180° umgelenkt, so dass sich letztlich zwei gerade Kabelabschnitte ergeben, nämlich ein erster, der von dem festen Installationspunkt zum Umlenkpunkt läuft, und ein zweiter, der vom Umlenkpunkt zum in der Aufbewahrungsstellung ebenfalls hinter einer Ladeklappe befindlichen Anschlussstecker läuft. Befindet sich der Installationspunkt und der Anschlussstecker an einer gemeinsamen Fahrzeugseite, so ergibt sich hiermit eine maximale Kabellänge bei einer einzigen Umlenkung, die ca. dem 1,5–1,7-fachen der Fahrzeugbreite entspricht. Denn das Kabel, das an einem geeigneten Bereich, beispielsweise unterhalb des Kofferraums oder dergleichen geführt werden kann, kann ahne Weiteres quer zur Fahrzeuglängsführung verlegt werden, wobei natürlich auch eine andere Verlegerichtung grundsätzlich denkbar ist, zumal mehrere Umlenkpunkte realisiert werden können.In the motor vehicle according to the invention, the cable is inserted in the cable storage, d. h., It runs in the cable memory essentially straight and is one or more times diverted. In this case, it is preferably deflected by approximately 180 °, so that ultimately two straight cable sections result, namely a first, which runs from the fixed installation point to the deflection point, and a second, which is located from the deflection point to in the storage position also behind a loading flap connector running. If the installation point and the connection plug are located on a common vehicle side, this results in a maximum cable length with a single deflection, which corresponds to approximately 1.5-1.7 times the vehicle width. Because the cable that can be performed at a suitable area, for example, below the trunk or the like, can be moved across the vehicle longitudinal guidance ahne other, of course, another installation direction is basically conceivable, especially as several deflection can be realized.
Im Umlenkpunkt wird das Ladekabel umgelenkt, der Winkel beträgt zwischen 90°–180°. Die Umlenkung kann dabei so gewählt werden, dass das Kabel keinen allzu engen Umlenkradius durchlaufen muss, so dass, nachdem in diesem Bereich, beispielsweise unterhalb des Kofferraums oder dergleichen hinreichend Raum gegeben ist, ohne Weiteres eine Umlenkung auch etwas starrer, dicker Ladekabel möglich ist.In the deflection point, the charging cable is deflected, the angle is between 90 ° -180 °. The deflection can be chosen so that the cable does not have to go through too narrow deflection radius, so that after in this area, for example, below the trunk or the like is given sufficient space, without further notice a deflection of some rigid, thick charging cable is possible.
Das Ladekabel wird aus dem Kabelspeicher gegen eine Rückstellkraft, gegebenenfalls unter Mithilfe einer Auszugshilfe in Form einer Übersetzung, herausgezogen, über welche das Kabel auch wieder in seine Aufbewahrungsstellung gebracht wird. Hierzu ist am Umlenkpunkt bevorzugt eine Umlenkführung vorgesehen, um die das Ladekabel läuft, welche Umlenkführung längsbeweglich gegen die Rückstellkraft beim Herausziehen des Ladekabels bewegbar ist. D. h., dass diese Umlenkführung beim Herausziehen des Kabels mitbewegt wird, mithin also in Richtung des aus dem Kabelspeicher gezogenen Kabels wandert. Der Umlenkpunkt bewegt sich also mit. Dabei kann als Umlenkführung entweder eine Umlenkrolle vorgesehen sein, deren Durchmesser im Hinblick auf den Leiter- oder Kabelquerschnitt entsprechend gewählt wird, oder eine Gleitführung, deren Umlenkradius ebenfalls entsprechend gewählt werden kann.The charging cable is pulled out of the cable storage against a restoring force, possibly with the help of a pull-out aid in the form of a translation, via which the cable is also returned to its storage position. For this purpose, a deflection guide is preferably provided at the deflection point, around which the charging cable runs, which deflection guide is movable longitudinally movable against the restoring force when pulling out the charging cable. D. h., That this deflection guide is moved when pulling out the cable, thus migrating in the direction of the towed cable from the cable storage. The deflection point thus moves with. It can be provided as Umlenkführung either a pulley whose diameter is chosen according to the conductor or cable cross-section, or a sliding guide, the deflection radius can also be selected accordingly.
Die Rückstellkraft wird bevorzugt mittels eines Federelements erzeugt, das beim Herausziehen des Ladekabels, gegebenenfalls unter Zwischenschaltung einer Übersetzung, damit die Herausziehkraft nicht zu groß wird, gespannt wird, wobei als Federelement bevorzugt eine Schraubenfeder oder eine Spiralfeder, mit der das Ladekabel oder die Umlenkführung direkt oder indirekt verbunden ist, verwendet werden kann. Je nach gegebener Bauraumsituation kann ein geeignetes Federelement zum Aufbau der Rückstellkraft verwendet werden.The restoring force is preferably generated by means of a spring element which, when pulling out the charging cable, optionally with the interposition of a translation, so that the pullout force is not too large, is stretched, as a spring element preferably a coil spring or a spiral spring, with the charging cable or the deflection directly or indirectly connected, can be used. Depending on the given installation space situation, a suitable spring element can be used to build up the restoring force.
Des Weiteren betrifft die Erfindung ein Kraftfahrzeug, umfassend einen Energiespeicher, der über ein fahrzeugseitig fest installiertes Ladekabel mit einem Anschlussstecker, das zum Verbinden mit einer externen Stromquelle aus einer Aufbewahrungsstellung aus dem Fahrzeug herausziehbar ist, aufladbar ist, wobei sich das Kraftfahrzeug dadurch auszeichnet, dass das Ladekabel in der Aufbewahrungsstellung schraubenförmig gewickelt und gegen seine Eigenelastizität herausziehbar ist, welche Eigenelastizität das Ladekabel in die Aufbewahrungsstellung zurückzieht.Furthermore, the invention relates to a motor vehicle, comprising an energy storage device which can be charged via a vehicle permanently installed charging cable with a connector that can be pulled out of the vehicle for connection to an external power source from a storage position, wherein the motor vehicle is characterized in that the charging cable is helically wound in the storage position and can be pulled out against its inherent elasticity, which inherent elasticity pulls the charging cable back into the storage position.
Bei dieser alternativen Erfindungslösung, die die erfindungsgemäße Aufgabe gleichermaßen löst, ist das Ladekabel von Haus aus, also herstellungsbedingt, schraubenförmig gewickelt. Es weist eine wicklungsbedingte Eigenelastizität auf, die es ermöglicht, dass das Kabel aus seiner Aufbewahrungsstellung, in welche es die Eigenelastizität automatisch zieht, herausgezogen werden kann, wobei sich über die Eigenelastizität eine Rückstellkraft aufbaut. Hierbei kann es beachtlich gelängt werden und zur Stromquelle geführt und dort angesteckt werden. Nach Beendigung des Ladevorgangs, wenn also das Ladekabel wieder entlastet wird, zieht die Eigenelastizität das Ladekabel wieder in die Aufbewahrungsstellung zurück, in welcher die einzelnen Windungen unmittelbar benachbart aneinander anliegen, mithin also das Ladekabel eine kleinformatige Form einnimmt.In this alternative invention solution that solves the task of the invention equally, the charging cable is home-made, so manufacturing reasons, helically wound. It has a winding-related inherent elasticity, which allows the cable from its storage position, in which it automatically pulls the inherent elasticity, can be pulled out, which builds on the inherent elasticity of a restoring force. This can be lengthened considerable and led to the power source and infected there. After completion of the charging process, that is, when the charging cable is relieved again, the inherent elasticity pulls the charging cable back to the storage position in which the individual turns abut directly adjacent to each other, thus therefore the charging cable assumes a small form.
Auch hier ist das Ladekabel fest am Fahrzeug angeordnet, also mit seinem einen Ende fest in elektrischer Verbindung mit dem Akkumulator geschaltet. Das andere Ende trägt den Anschlussstecker.Again, the charging cable is fixedly arranged on the vehicle, so connected at one end firmly in electrical connection with the accumulator. The other end carries the connector.
Zweckmäßigerweise ist hierbei das Ladekabel anschlusssteckerseitig mit einem in der Aufbewahrungsstellung aufgewickelten Seil oder Band verbunden, das beim Herausziehen des Ladekabels gegen eine Rückstellkraft abgewickelt wird und das Ladekabel unterstützend in die Aufbewahrungsstellung zurückzieht. Über dieses Band oder Seil, das auf einer kleinen Band- oder Seiltrommel aufgewickelt ist, wird der Rückzugsvorgang in die Aufbewahrungsstellung unterstützt. Beim Herausziehen des Kabels wird das Band oder das Seil gleichzeitig von der Trommel abgewickelt, hierbei baut sich trommelseitig eine Rückstellkraft auf. Nach Beendigung des Ladevorgangs zieht folglich die Eigenelastizität des Ladekabels das Kabel wieder in die Ausgangsstellung zurück, diese wird aber von dem Band oder Seil unterstützt, das auf die nun vorgespannte Trommel aufgewickelt wird. Hierdurch kann die Rückführbewegung noch weiter verbessert werden.Conveniently, in this case the charging cable connection plug side is connected to a wound up in the storage position rope or belt, which is unwound when pulling out the charging cable against a restoring force and withdraws the charging cable supportive in the storage position. About this tape or rope, which is wound on a small tape or rope drum, the withdrawal process is supported in the storage position. When pulling out the cable, the tape or the rope is simultaneously unwound from the drum, this builds a restoring force on the drum side. After completion of the charging process, therefore, the inherent elasticity of the charging cable pulls the cable back to the starting position, but this is supported by the tape or rope, which is wound onto the now biased drum. As a result, the return movement can be further improved.
Grundsätzlich befindet sich das Ladekabel, unabhängig von der konkreten Ausgestaltung des Kabelspeichers, in der Aufbewahrungsstellung in einem über eine zum Herausziehen über eine Klappe zu öffnenden Gehäuse. Dieses Gehäuse ist im Falle des geradlinig verlegten Ladekabels ein entsprechendes, länglich-schmales Gehäuse, im Falle des schraubenförmig gewickelten Ladekabels ein entsprechend dimensioniertes rechteckiges Gehäuse, das jeweils zur Aufnahme des Kabels in der Aufbewahrungsstellung ausgelegt ist.Basically, the charging cable, regardless of the specific configuration of the cable storage, is in the storage position in a case to be opened by a flap to open the housing. In the case of the straight-laid charging cable, this housing is a corresponding, oblong-narrow housing, in the case of the helically wound charging cable a suitably dimensioned rectangular housing, which is designed in each case for receiving the cable in the storage position.
Weiterhin kann, insbesondere an oder in dem das Ladekabel aufnehmenden Gehäuse, eine das Ladekabel insbesondere beim Einziehen reinigende Reinigungsvorrichtung vorgesehen sein. Hiermit wird das Ladekabel, das beim Ladevorgang gegebenenfalls verschmutzt wird, weil es am Boden aufliegt oder dergleichen, gereinigt und eine Verschmutzung des Fahrzeuginneren respektive Gehäuses vermieden.Furthermore, a cleaning device that cleans the charging cable, in particular when retracting, may be provided, in particular on or in the housing accommodating the charging cable. This is the charging cable, which may be dirty during charging, because it rests on the floor or the like, cleaned and pollution of the vehicle interior respectively housing avoided.
