Die Erfindung betrifft eine elektrische Ladekontaktvorrich tung für das elektrische Laden eines elektrischen Energie speichers eines autonomen Fahrzeugs, aufweisend einen Grund halter, einen Kontaktträger mit elektrischen Kontakten, die ausgebildet sind zum Kontaktieren an elektrischen Gegenkon takten. Die Erfindung betrifft außerdem eine zugehörige La destation und ein zugehöriges autonomes Fahrzeug. The invention relates to an electrical Ladekontaktvorrich device for the electrical charging of an electrical energy storage device of an autonomous vehicle, comprising a basic holder, a contact carrier with electrical contacts, which are designed to contact electrical counter contacts. The invention also relates to an associated charging station and an associated autonomous vehicle.
Die WO 2017/008895 Al offenbart ein autonomes Fahrzeug. WO 2017/008895 Al discloses an autonomous vehicle.
Aufgabe der Erfindung ist es, eine elektrische Ladekontakt vorrichtung, eine Ladestation mit einer solchen elektrischen Ladekontaktvorrichtung und/oder ein autonomes Fahrzeug mit einer solchen elektrischen Ladekontaktvorrichtung zu schaf fen, derart, dass ein autonomes Fahrzeug auf einfache Weise und mit geringem Zeitaufwand an eine Ladestation elektrisch angekoppelt werden kann, so dass ein elektrischer Energie speicher des autonomen Fahrzeugs an der Ladestation aufgela den werden kann. The object of the invention is to create an electrical charging contact device, a charging station with such an electrical charging contact device and / or an autonomous vehicle with such an electrical charging contact device, such that an autonomous vehicle can be electrically charged to a charging station in a simple manner and with little expenditure of time can be coupled so that an electrical energy store of the autonomous vehicle can be charged at the charging station.
Die Aufgabe wird gelöst durch eine elektrische Ladekontakt vorrichtung für das elektrische Laden eines elektrischen Energiespeichers eines insbesondere autonomen Fahrzeugs, auf weisend einen Grundhalter, einen Kontaktträger mit elektri schen Kontakten, die ausgebildet sind zum Kontaktieren an elektrischen Gegenkontakten, sowie eine Lagereinrichtung, die ausgebildet ist, den Kontaktträger relativ zum Grundhalter zumindest im Wesentlichen parallel zur Ebene eines Bodens verstellbar zu lagern. The object is achieved by an electrical charging contact device for the electrical charging of an electrical energy store, in particular an autonomous vehicle, having a base holder, a contact carrier with electrical contacts, which are designed to make contact with electrical mating contacts, and a bearing device, which is designed to mount the contact carrier so as to be adjustable relative to the base holder at least substantially parallel to the level of a floor.
Ein autonomes Fahrzeug weist im Allgemeinen ein Fahrwerk und an dem Fahrwerk um ihre Raddrehachsen drehbar gelagerte Räder auf, von denen wenigstens ein Rad angetrieben ist. Ein oder mehrere der Räder können gelenkte Räder sein. Ein oder mehre re der Räder können Omnidirektionalräder, wie beispielsweise Mecanumräder sein. Ein solches autonomes Fahrzeug weist im Allgemeinen auch eine Steuerungsvorrichtung auf, die ausge bildet und eingerichtet ist, die Räder automatisch anzutrei ben und/oder automatisch zu lenken, um das autonome Fahrzeug auf einem Boden mittels der Räder fahrend fortzubewegen und/oder zu navigieren. Autonome Fahrzeuge zeichnen sich ins besondere dadurch aus, dass sie keinen Fahrer aufweisen. Oft weisen autonome Fahrzeuge keinerlei Sitzplätze auf. Da derar tige autonome Fahrzeuge meist autark, d.h. selbstversorgt be trieben werden, weisen diese autonomen Fahrzeuge wenigstens einen elektrischen Energiespeicher auf, der in gewissen Zeit abständen aufgeladen werden muss. Aber auch Fahrzeuge, die keine autonomen Fahrzeuge sind, sondern durch einen Fahrer angesteuert, gefahren und/oder navigiert werden, können einen elektrischen Energiespeicher aufweisen, der ebenso in gewis sen Zeitabständen aufgeladen werden muss. An autonomous vehicle generally has a chassis and wheels that are rotatably mounted on the chassis about their wheel rotation axes on, of which at least one wheel is driven. One or more of the wheels can be steered wheels. One or more of the wheels can be omnidirectional wheels, such as mecanum wheels. Such an autonomous vehicle generally also has a control device which is designed and set up to automatically drive and / or automatically steer the wheels in order to move and / or navigate the autonomous vehicle on a floor by means of the wheels. Autonomous vehicles are particularly characterized by the fact that they have no driver. Autonomous vehicles often have no seats. Since such autonomous vehicles are mostly operated independently, that is to say they are self-sufficient, these autonomous vehicles have at least one electrical energy store which has to be charged at intervals. However, even vehicles that are not autonomous vehicles, but are driven, driven and / or navigated by a driver, can have an electrical energy store, which also has to be charged at certain intervals.
Der elektrische Energiespeicher ist dabei ein elektrisch wie deraufladbarer Energiespeicher und kann demgemäß beispiels weise galvanische Sekundärzellen umfassen und somit insbeson dere ein Akkumulator sein. Gegebenenfalls kann es sich aber beispielsweise auch um einen Kondensator oder allgemein um einen Wandler handeln, welchem Energie in Form von elektri scher Energie zuführbar ist, zum Speichern für eine Zeitdau ert ggf. in eine andere Energieform umgewandelt wird und zu einem späteren Zeitpunkt in elektrische Energie zurückgewan delt wird, um diese dann zu entnehmen. The electrical energy storage device is an electrical one like the rechargeable energy storage device and can accordingly comprise, for example, galvanic secondary cells and thus in particular be an accumulator. If necessary, however, it can also be, for example, a capacitor or a converter in general, to which energy in the form of electrical energy can be supplied, possibly converted into another form of energy for storage for a period of time and at a later point in time into electrical energy is converted back to then remove them.
Da die im elektrischen Energiespeicher vorhandene Energie so mit verbraucht wird, muss das Fahrzeug in gewissen Zeitab ständen an eine Ladestation gefahren werden, an welcher La destation der elektrische Energiespeicher des Fahrzeugs, ins- besondere des autonomen Fahrzeugs wieder aufgeladen werden kann . Since the energy present in the electrical energy store is also consumed in this way, the vehicle must be driven to a charging station at certain intervals, at which charging station the vehicle's electrical energy store, in particular special of the autonomous vehicle can be recharged.
Eine solche Ladestation ist im Allgemeinen ortsfest einge richtet und an ein elektrisches Netz angeschlossen bzw. an schließbar, welches elektrische Energie bereitstellt . Such a charging station is generally fixed and connected to an electrical network or closable, which provides electrical energy.
Die erfindungsgemäße elektrische Ladekontaktvorrichtung ist dabei ausgebildet die Ladestation mit dem Fahrzeug elektrisch vorübergehend derart zu verbinden, so dass der elektrische Energiespeicher des Fahrzeugs aus dem Netz elektrisch aufge laden werden kann. Nach einem Ladevorgang wird die elektri sche Verbindung zwischen Ladestation und Fahrzeug wieder ge löst, so dass das Fahrzeug sich wieder autark fortbewegen kann . The electrical charging contact device according to the invention is designed to temporarily connect the charging station to the vehicle electrically in such a way that the electrical energy store of the vehicle can be charged electrically from the network. After a charging process, the electrical connection between the charging station and the vehicle is released again, so that the vehicle can move independently again.
Nachteilig war es bisher jedoch, dass das Fahrzeug sehr posi tionsgenau an die Ladestation herangefahren werden musste, um die Kontakte der Ladekontaktvorrichtung mit den Gegenkontak ten zum Aufladen des elektrischen Energiespeichers in Über einstimmung zu bringen. Dabei waren bisher oft steuerungs technisch aufwändige und Zeit verschwendende Rangierbewegun gen des Fahrzeugs notwendig gewesen. However, it was previously a disadvantage that the vehicle had to be brought up to the charging station in a very precise position in order to bring the contacts of the charging contact device with the counter contacts for charging the electrical energy store into agreement. Up to now, maneuvering movements of the vehicle that were complex in terms of control technology and wasted time had previously been necessary.
Zum elektrischen Ankoppeln des elektrischen Energiespeichers des Fahrzeugs an die mit dem Netz verbundene Ladestation weist die Ladekontaktvorrichtung elektrische Kontakte auf, die mit korrespondierenden elektrischen Gegenkontakten wäh rend des Ladevorgangs Zusammenwirken. Wahlweise kann die La dekontaktvorrichtung an der Ladestation vorgesehen sein, wo bei die elektrischen Gegenkontakte dann an dem Fahrzeug vor gesehen sind. In diesem Fall sind die elektrischen Gegenkon takte des Fahrzeugs an den elektrischen Energiespeicher des Fahrzeugs angeschlossen. Alternativ, d.h. in einer umgekehr ten Anordnung, kann die Ladekontaktvorrichtung an dem Fahr- zeug vorgesehen sein, wobei die elektrischen Gegenkontakte dann an der Ladestation vorgesehen sind. In diesem Fall sind die elektrischen Kontakte der Ladekontaktvorrichtung des Fahrzeugs an den elektrischen Energiespeicher des Fahrzeugs angeschlossen . For electrically coupling the electrical energy store of the vehicle to the charging station connected to the network has the charging contact apparatus electrical contacts, the electrical contacts with corresponding counter-currency rend usammenwirken charging Z. The charging contact device can optionally be provided at the charging station, where the electrical counter contacts are then seen on the vehicle. In this case, the electrical Gegenkon contacts of the vehicle are connected to the electrical energy storage of the vehicle. Alternatively, ie in a reverse arrangement, the charging contact device can be Stuff be provided, the electrical mating contacts are then provided at the charging station. In this case, the electrical contacts of the charging contact device of the vehicle are connected to the electrical energy store of the vehicle.
In beiden alternativen Ausführungen weist die Ladekontaktvor richtung einen Grundhalter auf. Im Falle, dass die Ladekon taktvorrichtung an der Ladestation vorgesehen ist, weist der Grundhalter Verbindungsmittel auf, die zum ortsfesten Befes tigen der Ladekontaktvorrichtung an einem Boden, beispiels weise dem Fahrboden des Fahrzeugs ausgebildet sind. In diesem Fall kann das Verbindungsmittel in einer einfachen Ausführung schon durch Löcher oder Bohrungen in dem Grundhalter gebildet werden, über welche die Ladekontaktvorrichtung beispielsweise mittels Bodenankerschrauben an dem Boden festgeschraubt wer den kann. Im anderen Fall, bei dem die Ladekontaktvorrichtung an dem Fahrzeug vorgesehen ist, weist der Grundhalter Verbin dungsmittel auf, die zum Befestigen der Ladekontaktvorrich tung beispielsweise an einem Unterboden des Fahrzeugs ausge bildet sind. Auch in diesem Fall kann das Verbindungsmittel in einer einfachen Ausführung schon durch Löcher oder Bohrun gen in dem Grundhalter gebildet werden, über welche die Lade kontaktvorrichtung beispielsweise mittels Schrauben an dem Unterboden des Fahrzeugs festgeschraubt werden kann. In both alternative designs, the charging contact device has a basic holder. In the event that the charging contact device is provided at the charging station, the basic holder has connecting means which are designed for the stationary attachment of the charging contact device to a floor, for example the vehicle floor. In this case, the connecting means can be formed in a simple embodiment by holes or bores in the base holder, via which the charging contact device can be screwed to the floor, for example by means of floor anchor screws. In the other case, in which the charging contact device is provided on the vehicle, the basic holder has connecting means which, for fastening the charging contact device, are formed, for example, on an underbody of the vehicle. In this case too, the connecting means can be formed in a simple embodiment by holes or bores in the base holder, via which the charging contact device can be screwed to the underbody of the vehicle, for example by means of screws.
Der Kontaktträger weist die elektrischen Kontakte auf. Die elektrischen Kontakte können wenigstens zwei Lastkontakte um fassen, welche zur Übertragung der elektrischen Lastenergie aus dem Netz in den elektrischen Energiespeicher ausgebildet sind. Diese Lastkontakte sind insoweit mit dem Netz verbun den. Die elektrischen Kontakte können außerdem wenigstens zwei Steuerkontakte umfassen, welche ausgebildet bzw. einge richtet sind, ein bestimmungsgemäß richtiges Ankoppeln des Fahrzeugs an die Ladestation zu detektieren. Die Steuerkon- takte können auch ausgebildet bzw. eingerichtet sein, elekt rische Steuerbefehle zwischen dem Fahrzeug und der Ladestati on unidirektional oder bidirektional zu übertragen, um bei spielsweise einen Ladezyklus des elektrischen Energiespei chers steuern oder regeln zu können. Der Kontaktträger ist bezüglich des Grundhalters verstellbar gelagert. The contact carrier has the electrical contacts. The electrical contacts can include at least two load contacts, which are designed to transmit the electrical load energy from the network into the electrical energy store. To this extent, these load contacts are connected to the network. The electrical contacts can also include at least two control contacts, which are designed or set up to detect a correct coupling of the vehicle to the charging station. The tax con Cycles can also be designed or set up to transmit electrical control commands between the vehicle and the charging station unidirectionally or bidirectionally in order to be able to control or regulate, for example, a charging cycle of the electrical energy store. The contact carrier is adjustable in relation to the basic holder.
Die Lagereinrichtung ist demgemäß ausgebildet, den Kontakt träger bezüglich des Grundhalters verstellbar zu lagern. The storage device is accordingly designed to support the contact carrier adjustable with respect to the basic holder.
Die Lagereinrichtung ist erfindungsgemäß ausgebildet, den Kontaktträger zumindest im Wesentlichen parallel zur Ebene eines Bodens zu verstellen. Der Boden definiert sich dabei einerseits durch denjenigen Boden, auf welchem die Ladekon taktvorrichtung in ihrer ortsfesten Anordnung an der Ladesta tion befestigt ist und/oder andererseits durch die Fahrbahn bzw. den Fahrboden auf dem das Fahrzeug sich bewegt. Dies gilt insbesondere in der Ausführung, in welcher die Ladekon taktvorrichtung an dem Fahrzeug angeordnet ist. Im Allgemei nen kann gesagt werden, dass eine zumindest im Wesentlichen parallel zur Ebene eines Bodens erfolgende Verstellbarkeit des Kontaktträgers mit anderen Worten heißt, dass der Kon taktträger bezüglich des Grundhalters zumindest im Wesentli chen in einer horizontalen Ebene verstellbar ist. The bearing device is designed according to the invention to adjust the contact carrier at least substantially parallel to the level of a floor. The floor is defined on the one hand by the floor on which the charging contact device is fixed in its fixed arrangement to the charging station and / or on the other hand by the road or the floor on which the vehicle is moving. This applies in particular to the embodiment in which the charging contact device is arranged on the vehicle. In general, it can be said that an adjustability of the contact carrier, which takes place at least substantially parallel to the level of a floor, in other words means that the contact carrier is at least essentially adjustable in a horizontal plane with respect to the basic holder.
Die Lagereinrichtung kann den Kontaktträger mittels wenigs tens eines Drehlagers und/oder mittels wenigstens eines The bearing device can the contact carrier by means of at least one pivot bearing and / or by means of at least one
Schiebelagers relativ zum Grundhalter verstellbar lagern. Store the sliding bearing so that it is adjustable relative to the basic holder.
In einer speziellen Ausführungsform kann der Kontaktträger eine Tragplatte aufweisen, die sich in Ladeanfahrrichtung des elektrisch aufzuladenden autonomen Fahrzeugs längserstreckt, wobei die Lagereinrichtung ausgebildet ist, die Tragplatte quer zu ihrer Längserstreckung relativ zum Grundhalter ver stellbar zu lagern. In der Tragplatte sind die elektrischen Kontakte gegeneinan der elektrisch isoliert gelagert bzw. fest oder beweglich an geordnet, insbesondere befestigt. Die Tragplatte kann inso weit ausgebildet sein, die elektrischen Kontakte in definier ten Positionen und Abständen zueinander zu halten. Die Anord nung und die Abstände der elektrischen Kontakte zueinander korreliert insoweit mit der Anordnung und den Abständen der elektrischen Gegenkontakte. In a special embodiment, the contact carrier may have a support plate which extends longitudinally in the charging approach direction of the autonomous vehicle to be electrically charged, the bearing device being designed to support the support plate in an adjustable manner transversely to its longitudinal extension relative to the basic holder. In the support plate, the electrical contacts are mounted against each other in an electrically insulated or fixed or movable manner, in particular fastened. The support plate can be designed so far to keep the electrical contacts in defined positions and distances to each other. The arrangement and the spacing of the electrical contacts to one another correlate with the arrangement and the spacing of the electrical counter-contacts.
Die Ladeanfahrrichtung definiert sich durch die momentane we sentliche Fahrtrichtung des Fahrzeugs unmittelbar vor einem Ankoppeln des Fahrzeugs an die Ladestation. The charging approach is defined by the current essential direction of travel of the vehicle immediately before the vehicle is coupled to the charging station.
Die Längserstreckung der Tragplatte definiert sich insoweit auch als ihre Erstreckung in Richtung der Ladeanfahrrichtung, also der momentanen wesentlichen Fahrtrichtung des Fahrzeugs unmittelbar vor einem Ankoppeln des Fahrzeugs an die Ladesta tion. The longitudinal extent of the support plate is also defined as its extent in the direction of the loading direction, that is, the momentary essential direction of travel of the vehicle immediately before coupling the vehicle to the charging station.
Indem in der speziellen Ausführungsform die Lagereinrichtung ausgebildet ist, die Tragplatte quer zu ihrer Längserstre ckung relativ zum Grundhalter verstellbar zu lagern, bedeutet dies also, dass die Tragplatte im Wesentlichen senkrecht zur Ladeanfahrrichtung, also der momentanen wesentlichen Fahrt richtung des Fahrzeugs unmittelbar vor einem Ankoppeln des Fahrzeugs an die Ladestation verstellbar ist und zwar inso weit auch in der horizontalen Ebene. In the special embodiment, the bearing device is designed to mount the support plate so that it can be adjusted transversely to its longitudinal extension relative to the basic holder, this means that the support plate is essentially perpendicular to the loading approach direction, i.e. the current essential direction of travel of the vehicle immediately before coupling the Vehicle can be adjusted to the charging station, to that extent also in the horizontal plane.
Die Lagereinrichtung kann wenigstens eine Linearführung auf weisen, entlang welcher der Kontaktträger relativ zum Grund halter auf einer geraden Bahn verstellbar gelagert ist. The bearing device can have at least one linear guide, along which the contact carrier is adjustably mounted on a straight track relative to the basic holder.
Die Linearführung kann zwei in einem Abstand voneinander an geordnete, sich parallel zueinander erstreckende Führungsbah nen oder Führungsleisten aufweisen, die an dem Grundhalter befestigt sind, wobei jede Führungsbahn oder Führungsleiste wenigstens eine auf der jeweiligen Führungsbahn oder Füh rungsleiste laufende Führungsrolle oder Führungsbuchse auf weist, an welchen Führungsrollen oder Führungsbuchsen der Kontaktträger gelagert oder befestigt ist. The linear guide can have two at a distance from each other, parallel, mutually extending guide tracks or guide strips, which on the base holder are fastened, wherein each guide track or guide strip has at least one guide roller or guide bushing running on the respective guide track or guide rail, to which guide rollers or guide bushes the contact carrier is mounted or fastened.
Die Lagereinrichtung kann insbesondere ausgebildet sein, den Kontaktträger zwischen einer ersten Anschlagstellung und ei ner zweiten Anschlagstellung verstellbar zu lagern, wobei die Lagereinrichtung eine Federeinrichtung aufweist, welche aus gebildet ist, den Kontaktträger in einer zwischen der ersten Anschlagstellung und der zweiten Anschlagstellung liegenden Mittenstellung federelastisch vorzupositionieren. The bearing device can in particular be designed to adjustably mount the contact carrier between a first stop position and a second stop position, the bearing device having a spring device which is formed from pre-positioning the contact carrier in a central position lying between the first stop position and the second stop position .
Die Federeinrichtung kann wenigstens ein erstes Federelement aufweisen, das ausgebildet ist, den Kontaktträger durch seine Federspannung von der ersten Anschlagstellung wegzubewegen, und kann dabei wenigstens ein zweites Federelement aufweisen, das zu dem wenigstens einen ersten Federelement antagonis tisch ausgebildet ist, um den Kontaktträger durch seine Fe derspannung von der zweiten Anschlagstellung wegzubewegen, wobei durch das antagonistisch wirkende wenigstens eine erste Federelement und wenigstens eine zweite Federelement der Kon taktträger auslenkbar in seiner Mittenstellung zwischen der ersten Anschlagstellung und der zweiten Anschlagstellung ge halten ist. The spring device may have at least one first spring element which is designed to move the contact carrier away from the first stop position by means of its spring tension, and may have at least one second spring element which is formed antagonistically to the at least one first spring element in order to support the contact carrier through its Fe der tension to move away from the second stop position, with the antagonistic acting at least one first spring element and at least one second spring element of the contact carrier can be deflected in its middle position between the first stop position and the second stop position.
Der Kontaktträger, insbesondere die Tragplatte des Kontakt trägers kann in allen Ausführungsvarianten ergänzend eine An lauframpe aufweisen, die in Landeanfahrrichtung des The contact carrier, in particular the support plate of the contact carrier can additionally have an on ramp in all design variants, which in the landing direction of the
elektrisch aufzuladenden autonomen Fahrzeugs angeschrägt aus gebildet ist, um ein Aufgleiten von federvorgespannten, elektrischen Gegenkontakten des elektrisch aufzuladenden au tonomen Fahrzeugs auf die elektrischen Kontakte des Kontakt trägers zu unterstützen. Die Anlauframpe kann insoweit eine Schrägfläche aufweisen, die in Ladeanfahrrichtung des elektrisch aufzuladenden auto nomen Fahrzeugs ansteigend ausgebildet ist. Sind die Gegen kontakte federvorgespannt, dann werden sie entgegen der Fe dervorspannung in einer vertikalen Richtung weggedrückt, wenn das Fahrzeug an die Ladestation anfährt oder auffährt. Die Federvorspannung der Gegenkontakte kann einen guten elektri schen Übergang zu den Kontakten der elektrischen Ladekontakt vorrichtung gewährleisten bzw. verbessern. Autonomous vehicle to be electrically charged is beveled to support the sliding of spring-loaded, electrical counter-contacts of the electrically charged au tonome vehicle onto the electrical contacts of the contact carrier. In this respect, the start-up ramp can have an inclined surface which is designed to rise in the charging approach direction of the vehicle to be electrically charged. If the counter contacts are spring-loaded, then they are pushed against the spring preload in a vertical direction when the vehicle approaches or hits the charging station. The spring bias of the mating contacts can ensure or improve a good electrical transition to the contacts of the electrical charging contact device.
In allen Ausführungsvarianten der elektrischen Ladekontakt vorrichtung kann der Kontaktträger, insbesondere die Trag platte des Kontaktträgers eine erste seitliche Anlaufleiste und eine gegenüberliegende zweite seitliche Anlaufleiste auf weisen, durch welche Anlaufleisten eine Ladeanfahrbewegung des elektrisch aufzuladenden autonomen Fahrzeugs in eine quer zur Landeanfahrrichtung erfolgende Auslenkbewegung des Kon taktträgers, insbesondere der Tragplatte des Kontaktträgers entlang der Verstellrichtung der Lagereinrichtung umgesetzt wird . In all design variants of the electrical charging contact device, the contact carrier, in particular the support plate of the contact carrier, can have a first lateral contact strip and an opposite second lateral contact strip, by means of which contact strips a charging start-up movement of the autonomous vehicle to be electrically charged into a deflection movement of the contact carrier that takes place transversely to the approach direction , in particular the support plate of the contact carrier is implemented along the adjustment direction of the bearing device.
Die Anlaufleisten dienen folglich jeweils zum Anlaufen der Zentriervorrichtung einer der beiden gegenüberliegende An laufschrägen der Zentriervorrichtung, um den Kontaktträger, insbesondere die Tragplatte des Kontaktträgers der elektri schen Ladekontaktvorrichtung durch eine Fahrbewegung des au tonomen Fahrzeugs relativ zum Grundhalter während eines auto nomen Ladeanfahrens des autonomen Fahrzeugs auszulenken. The stop bars are thus used to start the centering device one of the two opposite slopes on the centering device in order to deflect the contact carrier, in particular the support plate of the contact carrier of the electrical charging contact device by a movement of the autonomous vehicle relative to the basic holder during an autonomous charging process of the autonomous vehicle .
In einer speziellen kombinierten Ausführung kann die elektri sche Ladekontaktvorrichtung eine am Kontaktträger, insbeson dere an der Tragplatte des Kontaktträgers angeordnete Anlauf rampe aufweisen, die einerseits durch eine erste seitliche Anlaufleiste und andererseits durch eine zweite seitliche An laufleiste seitlich begrenzt wird, wobei auch hierbei die An- lauframpe in Ladeanfahrrichtung des elektrisch aufzuladenden autonomen Fahrzeugs angeschrägt ausgebildet ist, um ein Auf gleiten von federvorgespannten, elektrischen Gegenkontakten des elektrisch aufzuladenden autonomen Fahrzeugs auf die elektrischen Kontakte des Kontaktträgers zu unterstützen. In a special combined design, the electrical charging contact device can have a ramp arranged on the contact carrier, in particular on the support plate of the contact carrier, which is limited on the one hand by a first lateral contact strip and on the other hand by a second lateral contact strip, with the An - Run ramp is chamfered in the charging direction of the autonomous vehicle to be electrically charged in order to support a sliding on spring-biased, electrical mating contacts of the autonomous vehicle to be electrically charged onto the electrical contacts of the contact carrier.
