Description
Die Erfindung betrifft eine Ladedose mit einer Verriegelungsvorrichtung für ein Elektro-Fahrzeug zur Aufnahme eines Ladesteckers einer Ladeeinrichtung gemäß dem Oberbegriff des Anspruches 1. Der Begriff Elektro-Fahrzeug wird hier als Sammelbegriff für alle Fahrzeuge mit einer aufladbaren Traktionsbatterie verwendet.The invention relates to a charging socket with a locking device for an electric vehicle for receiving a charging plug of a charging device. The term electric vehicle is used here as a collective term for all vehicles with a chargeable traction battery.
Eine gattungsgemäße Verriegelungseinrichtung mit einem Stellantrieb für einen elektrisch bewegbaren Riegel ist aus
Es ist allgemein bekannt, dass die im Stand der Technik eingesetzten Riegelstifte bisher nur aus einfachen Thermoplasten, wie beispielsweise aus Polyamid 6 (PA6) oder Polybutylenterephthalat (PBT) oder aus Metall hergestellt sind. Es hat sich gezeigt, dass bei Riegelstiften aus diesen Materialien bei Ladevorgängen unter ungünstigen Bedingungen erhebliche Probleme auftreten können, wobei Riegelstifte nicht mehr entriegelt und damit Ladestecker nicht mehr aus Ladedosen gelöst werden können. Solche ungünstigen Ladebedingungen können insbesondere bei Ladestationen im Freien witterungsbedingt auftreten, wenn beispielsweise bei Minustemperaturen über Nacht der Ladestecker in der Ladedose verbleibt und bei einer Eisbildung der Riegelstift in seiner Verriegelungsposition festfriert. Bei einem Schnell-Ladevorgang kann zudem aufgrund von Temperaturschwankungen Kondensat anhaften, welches bei Minustemperaturen wiederum zur Eisbildung führen kann. Trotz einer mechanischen Notentriegelungseinrichtung kann ein so festsitzender Riegelstift gegebenenfalls nicht oder nur mit erheblichem Kraftaufwand entriegelt werden. Zur Lösung der vorstehenden Probleme ist bisher nur einer aufwendiger Schutz der Ladedosen vor Feuchtigkeit möglich. Zudem haben bisher verwendete Riegelstifte einen relativ hohen Verschleiß und eine gegebenenfalls unzureichende mechanische Festigkeit, wodurch die Funktion einer Verriegelungsvorrichtung negativ beeinflusst und im Extremfall zu einem Ausfall der Verriegelungseinrichtung führen kann.It is generally known that the locking pins used in the prior art have so far only been made from simple thermoplastics, such as polyamide 6 (PA6) or polybutylene terephthalate (PBT) or from metal. It has been shown that locking pins made of these materials can cause considerable problems during charging under unfavorable conditions, with locking pins no longer being able to be unlocked and thus charging plugs no longer being able to be detached from charging sockets. Such unfavorable charging conditions can occur in particular in outdoor charging stations due to the weather, for example if the charging plug remains in the charging socket overnight at sub-zero temperatures and the locking pin freezes in its locking position when ice forms. During a fast charging process, condensation can also build up due to temperature fluctuations, which in turn can lead to ice formation at sub-zero temperatures. Despite a mechanical emergency unlocking device, a locking pin that is stuck in this way may not be able to be unlocked, or only with considerable effort. Up to now, the only way to solve the above problems was to protect the charging sockets from moisture, which was expensive. In addition, the locking pins used to date have a relatively high level of wear and tear and possibly insufficient mechanical strength, which has a negative effect on the function of a locking device and, in extreme cases, can lead to a failure of the locking device.
Aufgabe der Erfindung ist es daher, eine gattungsgemäße Ladedose mit einer Verriegelungsvorrichtung so weiterzubilden, dass die Verriegelungsvorrichtung mit einer einfachen Maßnahme eisresistent funktioniert und zudem verschleißarm ist und eine hohe mechanische Festigkeit aufweist.The object of the invention is therefore to further develop a generic charging socket with a locking device in such a way that the locking device functions ice-resistant with a simple measure and is also low-wear and has a high mechanical strength.
Die Aufgabe ist durch die Merkmale des Anspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of
Gemäß dem kennzeichnenden Teil des Anspruches 1 ist der Riegelstift aus Polyphthalamid (PPA) hergestellt. Es hat sich herausgestellt, dass der aus PPA hergestellte Riegelstift im Vergleich zu aus dem Stand der Technik bekannten Riegelstiften eine wesentlich ausgeprägtere Eisresistenz, Verschleißarmut sowie eine hohe mechanische Festigkeit bereitstellt.According to the characterizing part of
In einer Vielzahl von Experimenten wurde ein Material für einen Riegelstift einer gattungsgemäßen Ladedose gesucht, mit dem ein Verriegelungsstift nicht mehr festfriert und zudem einen sehr geringen Abrieb bei hoher mechanischer Belastbarkeit aufweist. Als erfolgreich wurde dazu nach einer Reihe aufwendiger Fehlversuche das Material Polyphthalamid (PPA) identifiziert. Ein damit hergestellter Riegelstift zeichnet sich einerseits durch hohe mechanische Festigkeit und Härte aus und es hat sich überraschend gezeigt, dass vergleichsweise eine Tendenz zum Festfrieren erheblich verringert ist und ein solcher Riegelstift auch bei ungünstigen Umgebungsbedingungen regelmäßig nicht festfriert. Tritt aber bei sehr ungünstigen Witterungsbedingungen trotzdem eine Eisbildung auf, ist der Riegelstift stark genug, um ohne eine Beschädigung entriegelt zu werden. Eine solche Entriegelung kann dadurch unterstützt werden, dass der aus PPA hergestellte Riegelstift mit einfacheren Thermoplasten, insbesondere mit Polyamid (PA) in der Ladedose kombiniert ist, da dabei intermolekulare Anziehungskräfte und Reibungskräfte nur gering sind, wodurch auch eine Entriegelungskraft entsprechend gering ist.In a large number of experiments, a material for a locking pin of a generic charging socket was sought, with which a locking pin no longer freezes and also has very low abrasion with high mechanical strength. After a series of costly and failed attempts, the material polyphthalamide (PPA) was identified as successful. A locking pin produced in this way is characterized on the one hand by high mechanical strength and hardness and it has surprisingly been shown that the tendency to freeze is comparatively significantly reduced and such a locking pin does not freeze even under unfavorable environmental conditions. However, if ice does form under very unfavorable weather conditions, the locking pin is strong enough to be unlocked without damage. Such unlocking can be assisted by the fact that the made of PPA Locking pin is combined with simpler thermoplastics, in particular with polyamide (PA) in the charging socket, since intermolecular forces of attraction and frictional forces are only low, which means that an unlocking force is correspondingly low.
Weiter hat sich gezeigt, dass insbesondere bei Schnellladevorgängen bei einem erfindungsgemäßen Riegelstift aus PPA ein Anhaften von Kondensat durch Temperaturschwankungen weitestgehend vermieden wird.It has also been shown that, particularly in the case of rapid charging processes, with a locking pin made from PPA according to the invention, the adhesion of condensate due to temperature fluctuations is largely avoided.
In an sich bekannter Weise kann der Riegelantrieb ein von einer Bordelektronik des Elektrofahrzeugs steuerbarer, motorischer Linearantrieb für den Riegelstift sein, der an der Ladedose angeordnet ist.In a manner known per se, the locking drive can be a motorized linear drive for the locking pin, which can be controlled by on-board electronics of the electric vehicle and is arranged on the charging socket.
Am Riegelantrieb kann zudem eine mechanische, vorzugsweise unmittelbar oder mittelbar, insbesondere handbetätigbare Notentriegelungseinrichtung angeordnet sein. Vorteilhaft sind auch hier die aufzuwendenden Notentriegelungskräfte gering, wenn der aus PPA hergestellte Regelstift mit einfacheren Thermoplasten, insbesondere mit Polyamid (PA) in der Ladedose kombiniert ist.A mechanical, preferably directly or indirectly, in particular manually actuated, emergency unlocking device can also be arranged on the bolt drive. Here, too, the emergency release forces to be applied are advantageously low if the control pin made from PPA is combined with simpler thermoplastics, in particular with polyamide (PA) in the charging socket.
Vorzugsweise werden Getriebeteile im Riegelantrieb zur Verlagerung des Riegelstifts aus Hochleistungspolymeren, wie Polyphenylensulfid (PPS) und/oder metallischen Werkstoffen hergestellt, um relativ hohe Antriebskräfte für den Riegelstift zu ermöglichen. In neuen Standardausführungen von Ladeschnittstellen für Elektrofahrzeuge sind in der Ladedose und/oder im Ladestecker Verriegelungsfenster zur Führung und/oder für einen Verriegelungseingriff des Riegelstifts vorgesehen. Für eine ordnungsgemäße Verriegelung muss der Riegelstift diese Verriegelungsfenster treffen, was gegebenenfalls durch ein Verkippen des Ladesteckers aufgrund seines Eigengewichts und angeschlossener schwerer Ladekabel schwierig sein kann. Es wird daher vorgeschlagen, den Riegelstift zum freien Ende hin konisch verjüngend auszubilden und/oder den freien Endbereich anzufasen, um die Einführung in solche Fensteröffnungen zu vereinfachen und zu unterstützen. Zudem kann eine konische Ausführung eines Riegelstifts eine Entformung bei seiner Herstellung unterstützen. Transmission parts in the bolt drive for shifting the bolt pin are preferably made of high-performance polymers, such as polyphenylene sulfide (PPS) and/or metallic materials, in order to enable relatively high driving forces for the bolt pin. In new standard designs of charging interfaces for electric vehicles, locking windows are provided in the charging socket and/or in the charging plug for guiding and/or for locking engagement of the locking pin. For proper locking, the locking pin must hit this locking window, which can be difficult if the charging plug tilts due to its own weight and heavy charging cables that are connected. It is therefore proposed to design the locking pin to taper conically towards the free end and/or to bevel the free end area in order to simplify and support the introduction into such window openings. In addition, a conical design of a locking pin can support demoulding during its manufacture.
