Definitions

  • the invention relates to a positioning device for a quick-charging system, a quick-charging system and a method for contacting electrically driven vehicles, in particular passenger cars, trucks, buses or the like, the quick-charging system comprising a charging contact device that can be arranged on a vehicle floor of a vehicle and a contact device that can be arranged on or at least partially in a surface that the vehicle can drive on underneath the vehicle, the contact device having contacts with which one charging contact of the charging contact device can be contacted to form a contact pairing, with one Positioning device of the positioning device, the contact device can be positioned relative to the charging contact device at least in a vertical direction and in a horizontal direction in a contact position, such that an electrically conductive connection between the vehicle and a stationary charging station can be formed in the contact position.

  • a rapid charging system is known from WO 2019/223906 A1, in which the rapid charging system is arranged underneath a floor of the vehicle.
  • a contact device is attached here directly to a substrate and can be run over and contacted by the vehicle in question.
  • the disadvantage here is that the vehicle or its charging contact device must be positioned very precisely above the contact device.
  • a positioning device can also be provided underneath the vehicle, which aligns a contact device relative to a charging contact device and brings them together to form a contact pairing.
  • the positioning device can be installed both on the vehicle and on or below a substrate. A pit or a similar type of recess can then be formed in the subsurface, within which a part of the rapid charging system is accommodated.
  • a control of the positioning device is regularly required, which recognizes a relative position of contact device and charging contact device and controls drives of the positioning device accordingly, so that the contact position is actually achieved in the desired manner.
  • the disadvantage here is that the contact device and charging contact device can only be brought together slowly due to the high accuracy requirements and possibly disruptive environmental conditions. Vehicle movements during a contacting process or a charging process can easily lead to an interruption of the same if the contact device is thereby displaced relative to the charging contact device.
  • the present invention is therefore based on the object of proposing a positioning device, a rapid charging system and a method for contacting electrically driven vehicles which enables rapid and reliable contacting.
  • This object is achieved by a positioning device having the features of claim 1, a rapid charging system having the features of claim 18 and a method having the features of claim 22.

  • the positioning device can be arranged underneath the vehicle, it is essentially out of the reach of people during a contacting process, so that large currents can be transmitted. At the same time, it is possible that a person driving the vehicle does not have to position it very precisely at the charging station.
  • An automated bringing together of contact device and charging contact device is carried out by means of the positioning device.
  • the positioning device moves the contact device relative to the charging contact device in the vertical direction and at least one horizontal direction relative to the substrate or a contact plane in the contact position. The movement in the respective directions can take place simultaneously or in successive movement sections or successively.

  • a compensating movement in a vertical direction does not necessarily have to be performed with the compensating unit.
  • a compensatory movement in a vertical direction can be easily performed by the positioning device by driving the positioning device.
  • this inaccuracy can be corrected independently of the positioning device by means of the compensation unit.
  • This correction is given by the possibility that the contact device can move relative to the charging contact device independently of the positioning device.
  • This compensating movement can be initiated, for example, by the contact device being brought together with the charging contact device in the manner of a plug-socket connection, i.e. the contact device and the charging contact device each being designed in such a way that the contact position can only be achieved by positive locking if there is a clear relative alignment.
  • the contact device is designed like a dome and the charging contact device is designed with a matching trough-like shape.
  • a movement of the vehicle relative to a ground during a charging process can also be compensated with the compensation unit when the contact device and the charging contact device are already in contact with one another or are firmly connected.
  • a readjustment of the positioning unit is then not necessary and there is also no interruption of the charging process in the case of such a relative movement.
  • an interruption of a charging process due to vehicle movement is avoided, whereby a charging process can be carried out safely.
  • the positioning device can have at least one drive, by means of which the contact device can be moved relative to the charging contact device, it being possible for the compensation unit to be designed without a drive.
  • the drive can then be designed in such a way that a movement in the vertical direction and in the horizontal direction is possible.
  • the positioning device can be formed by appropriate guides, an articulated arm or the like, which enables positioning movements in several axes, relative to a three-dimensional coordinate system.
  • a drive can be one or more pneumatic cylinders, for example.
  • the compensating unit can then perform compensating movements that are independent of the positioning movements in the respective axes.
  • the positioning device can include a controller, by means of which actuators of the drive of the positioning device can be controlled in such a way that the contact device or the charging contact device can be moved from a storage position to the contact position and back.
  • the controller can, for example, be in the form of a programmable logic controller and/or a computer.
  • the actuators can be hydraulically, pneumatically or electrically driven actuators.
  • electric motors can be provided as a drive.
  • the electric motors can also be easily controlled in terms of acceleration and movement speed by means of the controller.
  • a possible movement range of the positioning device is many times larger in relation to a possible range of movement of the compensation unit.
  • the balancing unit can allow movement of the vehicle in the contact position in at least the horizontal direction relative to the ground. In this way, the vehicle can also be moved during a loading process, since the compensating unit can perform a free compensating movement that is independent of a movement of the positioning device. A pivoting movement of the vehicle, for example as a result of a loading or unloading process, cannot then lead to the contact device being displaced relative to the charging contact device as a result of the vehicle movement.
  • the compensating movement can be in one or more horizontal directions. In principle, any movement of the vehicle can be compensated with the compensation unit.
  • At least the contact device can be designed so that the vehicle can drive on and/or drive over it.
  • the positioning device can consequently have an overall height which, as a result of the arrangement of the positioning device on or in the ground, is so great that it does not block a route of the vehicle.
  • the compensating unit can have a compound table.
  • the cross table can be designed in such a way that at least movements in two horizontal directions, relatively orthogonal to one another, are made possible.
  • the compound table can be designed with a comparatively low overall height, so that the height of the positioning device is not significantly increased by the compensating unit.
  • the compensation unit can have two, preferably three, particularly preferably four, frame supports, wherein the frame supports can be connected to one another via sliding joints and/or rotary joints and can be designed to be movable and/or tiltable relative to one another in the horizontal direction.
  • the frame beams can be coaxial with each other, relatively related on a vertical vertical axis.
  • the frame supports can be arranged one inside the other and/or one above the other in the manner of a stack arrangement.
  • the frame supports can be designed in different sizes, so that a second frame support is arranged inside a first frame support and a third frame support etc. is arranged inside the second frame support. Since only a comparatively small compensating movement is to be made possible with the compensating unit, this space-saving arrangement of the frame supports is possible.
  • the frame supports can be connected to one another via sliding and/or rotary joints, so that the frame supports can be linearly displaced and/or tilted relative to one another.
  • At least one frame support can advantageously be made of a dielectric material.
  • a frame support may be formed entirely or partially from the dielectric material such as plastic. This results in particularly good electrical insulation, in particular of current-carrying components of the positioning device from the environment or the positioning device and the compensation unit.
  • At least one frame support can be designed with a support structure extending in a horizontal plane, it being possible for passage openings for electrical conductors of the positioning device to be formed within the support structure.
  • the support structure can be a honeycomb structure, rib structure, or lattice structure. Consequently, the passage openings between the ribs or material sections of the structure are formed so large that conductors of the positioning device can be passed through.
  • the conductors can be cables, strands, flat strands, sliding contacts, busbars or the like for connecting the contacts or charging contacts to a power source of the charging station or a battery in the vehicle. Cabling of the fast charging system can thus be made particularly compact with short conductor sections become. At the same time, the conductors can then also perform a movement as a result of a movement of the positioning device.
  • the conductors of the positioning device can be passed through the through-openings and can be designed as non-insulated conductors, at least in sections. If the frame support with the through-openings is made of a dielectric material, the conductors can be uninsulated in the area of the through-openings, i.e. they can have no insulating layer. In this way, for example, a broken cable as a result of multiple movement of cables during recurring positioning movements of the positioning device can be prevented. Provision can then also be made for a conductor to be guided through each through-opening alone. This can ensure that the conductors do not come into contact with one another. A free movement of the compensating unit is then also not significantly mechanically influenced by the ladder.
  • the conductors can then move in a narrow space.
  • the conductors can also be insulated in one area of the positioning device. It may be possible here to guide the conductors in such a way or to provide such long conductors or cables so that a cable break as a result of repeated movements is avoided.
  • the compensation unit can be designed with a fastening device for the contact device or charging contact device.
  • the fastening device is then designed in such a way that the contact device or the charging contact device can be easily mounted on a fastening device.
  • the fastening device can be in the form of a plate or the like, on which the contact device or the charging contact device can be mounted using screws or other fastening means.
  • the compensating unit can be designed with a first guide and a second guide, wherein the guides can enable movements along a first coordinate axis X and a second coordinate axis Y running orthogonally to the first coordinate axis.
  • the guides or coordinate axes run essentially in a horizontal plane, so that a compensating movement within the horizontal plane with the compensating unit is possible.
  • the guides can each be formed from two parallel tracks, each with a carriage guided on the track.
  • the tracks may be formed by a rail, rod or the like, in which case the carriage may be in the form of a carriage or bush.
  • the two parallel paths make it possible to form a guide that does not tend to tilt, even with a comparatively short carriage.
  • the compensating unit can be designed with at least one restoring device that can position a carriage in a central position of the guide.
  • the restoring device can then center the carriage and thus the respective guide in the central position. It is thus possible for the contact device or the charging contact device to be in a central position relative to the compensation unit before it is brought together into the contact position, from which the compensation movement can then be carried out.
  • the springs can be unloaded with a force or can be prestressed in such a way that the respective spring forces cancel each other out in the middle position. In this way it can be ensured that a compensating movement is always possible in each case and that the contact device or the charging contact device assumes a defined position during the bringing together.
  • the restoring device can be formed by two springs, preferably compression springs, which can be arranged opposite one another on both sides of the carriage.
  • the springs can along the j ewei- ligen guide on each side of the carriage or at another suitable location. A compensatory movement can then lead to a contraction and an expansion of the respective opposing springs.
  • the compensating unit can be designed with a first axis and a second axis, wherein the axes can enable rotational movements about a first axis of rotation X′ and about a second axis of rotation Y′ running orthogonally to the first axis of rotation.
  • the compensating unit can consequently be designed in such a way that it can be tilted or pivoted at least partially about the first axis and about the second axis.
  • By means of the axes it is then possible to tilt the contact device or the charging contact device at an angle relative to a horizontal plane in such a way that the contact device or the charging contact device is aligned with a vertical axis orthogonal to the horizontal plane.
  • the compensating unit can be designed with a further axis, wherein the further axis can enable a rotational movement about a further rotational axis Z running orthogonally to the coordinate axes X, Y.
  • the further axis or further axis of rotation Z is then positioned in a vertical plane relative to the horizontal plane and enables parts of the compensation unit and thus the contact device or the charging contact device to rotate relative to one another. Consequently, the contact device can be moved or pivoted relative to the charging contact device about a common vertical axis, so that a relative relative to a horizontal Plane non-rotationally symmetrical contact device and / or charging contact device can perform a compensating movement in the desired manner by rotation, for example to produce a form fit in the contact position.
  • the compensating unit can be designed with at least one further restoring device which can position at least one of the axles in an angular position.
  • the further restoring device can be formed by at least one spring, preferably a torsion spring, which can be arranged on the axle and/or an axle bearing.
