Definitions

  • the invention relates to a device for conductive charging, in particular of electric vehicles at a fixed station, according to the features of the preamble of claim 1
  • a plug connection for connecting in particular electrical lines comprising at least one female connecting element and one male
  • Connecting element the female connecting element receiving the male connecting element in a form-fitting manner and wherein the two connecting elements can be non-positively and releasably connected in the case of form-fitting contact, and wherein a connecting region of the male connecting element is formed coaxially tapering and comprises at least one displaceable contact body which is in a first position within and is arranged projecting from the male connecting element in a second position.
  • conductive charging in particular of electric vehicles, is possible at a base station.
  • One connecting element is arranged on the autonomously driving vehicle, whereas the other connecting element is arranged in a stationary manner, but can be moved there within certain limits. If the vehicle moves with its connecting element in the direction of the fixed connecting element, these two connecting elements are brought into operative connection by the respective contact bodies of the two for electrical contacting Connecting elements are brought into connection with one another so that the charging current can then flow.
  • the contact elements (contact body) of the male connecting element are arranged movably in this male connecting element. In a first position, they are arranged entirely within the male connecting element, so that this contact body is protected against contact and contamination. Only when the two connecting elements have been brought together does the contact body, which was previously located within the connecting element, move out of the male connecting element, so that these contact bodies can be contacted with the associated contact bodies of the female connecting element.
  • the invention provides an improved device for conductive charging.
  • Conductive charging means that the electrical contacts of a base station at which charging energy is made available are operatively connected to electrical contacts of an autonomously driving vehicle, so that they touch each other for charging. Compared to the well-known inductive charging, which takes place without contact, this conductive charging has the advantage of significantly higher energy transmission, so that autonomously driving vehicles are charged much faster and are ready for operation again.
  • a vehicle unit for the entire device for conductive charging, which is arranged on the vehicle, in particular the electric vehicle.
  • a robot unit is provided which can be controlled by the vehicle for the purpose of charging.
  • the robot unit is thus stationary, but within certain limits at the location, on which to load, movable. The purpose of this is that the vehicle with its vehicle unit does not have to control the robot unit 100 percent, but rather that the robot unit searches for the vehicle unit when the vehicle has been parked for charging.
  • the object of the invention is to improve the contacts both on the vehicle unit side and on the robot unit side of the device for conductive charging. This object is solved by the features of claim 1.
  • the at least one contact of the robot unit has a base from which a cylinder section and a contact lug originates and the at least one contact of the vehicle unit has a base from which at least one contact spring and a contact lug originates.
  • the base of the contact of the robot unit achieves a stiffness of this contact, which is additionally increased by the cylinder section protruding from the base.
  • the cylinder section in turn forms a sufficiently large contact area for the at least one contact, preferably for the multiple contacts of the robot unit. This ensures robust contacting and high operational reliability.
  • This is further increased by the fact that the at least one contact of the vehicle unit has the base from which at least one contact spring, again preferably a plurality of contact springs, originates.
  • each contact has at least one contact lug, preferably exactly one contact lug, with which this respective contact via downstream lines, optionally with the interposition of plug connections, with a control device and / or an energy source for charging and / or the like can be connected.
  • the cylinder section has at least one recess, preferably a plurality of recesses arranged over the circumference of the cylinder section.
  • the at least one recess or the plurality of recesses arranged over the circumference of the cylinder section have the advantage that the rigidity of the cylinder section is deliberately reduced somewhat in order to enable play compensation when the contact of the robot unit with the associated contact of the vehicle unit is brought together. It goes without saying that the contact, in particular a contact spring, of the vehicle unit is not guided into the area of a respective recess, but into an area of the cylinder section next to a respective recess and comes into contact there for the purpose of contacting.
  • the base of the contact is formed by a plurality of base sections arranged over the circumference, a contact spring projecting vertically between two base sections in each case.
  • a geometrical embodiment of this contact is thus available, which can be automated very well and in large numbers and thus reduced in cost known stamping and bending process or a known stamping and rolling process or a combination of these two processes can be produced.
  • the contact spring has an angled portion at its free end.
  • the connection of the contact spring to the base of this contact brings about a certain flexibility, in order to compensate for tolerances and, above all, to facilitate centering when the vehicle unit and robot unit are brought together.
  • This ease of centering and also the increase in the contact force is further improved in that the contact spring has an angled portion at its free end.
  • This advantageous relief is achieved in particular when the angled end of the free end of the contact spring is at a distance, in particular at a plane-parallel distance, from the base section of the contact spring.
  • a spring force is achieved not only by the contact spring projecting, preferably perpendicularly, from the base, but also by angling the end portion of the contact spring at its free end.
  • the contact elements of the robot unit are recessed in a housing and are therefore protected from external contact or contamination, but are accessible to the contact elements of the vehicle unit.
  • the contact elements of the vehicle unit must also be protected against contact or contamination.
  • the contact elements of the vehicle unit are covered by a gripping protection, so that the contact elements of the vehicle unit are not accessible as long as there is no charging and as long as the vehicle unit has not been brought into operative connection with the robot unit.
  • the gripping protection Only when the robot unit is moved in the direction of the vehicle unit is this gripping protection moved by the robot unit relative to the housing of the vehicle unit, so that the contact elements of the vehicle unit, the are fixedly arranged in the housing of the vehicle unit, can be released and can intervene in the corresponding free spaces in the robot unit in order to touch and contact the contact elements of the robot unit located there.
  • the gripping protection is supported on the housing of the vehicle unit by means of springs.
  • This configuration has the essential advantage that the gripping protection is moved as a mechanical component in relation to the housing of the vehicle unit, whereas the contact elements of the vehicle unit are arranged in a fixed position in it, since in practice a movable mechanical component (without electrical function) is much better can be realized as an electrically conductive component, which in the case of the prior art not only serves for electrical contacting, but which also has to be moved at the same time As a result, the invention realizes a much simpler and safer construction of the device for conductive charging.
  • the contacts are also arranged fixed in the housing of the robot unit.
  • the contacts in the robot unit and the vehicle unit are extrusion-coated in some areas for the purpose of their fixing in the respective housing, a portion of the contacts remaining free after the molding process for the purpose of contacting or connecting supply lines.
