Definitions

  • a charging system is known in which contact units are arranged in a contact unit carrier that can be fastened to a floor.
  • the contact units are each made up of contact elements with a lever arm and a spring-loaded pivot bearing.
  • the contact elements are also designed so that they protrude at different heights relative to a surface of the contact unit carrier facing the charging contact device. It is thus possible to maintain a desired contact sequence of contact pairings when merging the contact device and charging contact device or when separating them.
  • the body can be formed with a base element which forms the surface of the contact unit carrier facing the charging contact device. Since the surface of the contact unit carrier usually comes into contact with charging contacts of the charging contact device during a contacting process, it is particularly advantageous if this surface is made of a dielectric material. It is then also possible for the pivot bearings to be formed on the base element. With the base element, together with the contact elements or contact units, an assembly can then be created, which significantly simplifies further assembly of the contact device.
  • the base element can, for example, be designed in one piece and assembled with other components of the body.
  • the pivot bearing can be formed by at least one bearing eye or at least one bearing pin of the body, wherein the bearing eye or the bearing pin can be attached to a respective mounting base of the body by means of a screw connection.
  • the pivot bearing can have a bearing bush made of a dielectric material on an axis of the pivot bearing. This makes it possible for pivot bearings to be made from a conductive material, such as metal.
  • the bearing bush can, for example, be pressed into a bearing eye or onto the axle and thereby firmly mounted there. In addition to radial storage, axial storage can also be implemented using the bearing bush. If the pivot bearing is formed, for example, by two bearing eyes or bearing journals, two bearing bushes can also be used.
  • the bearing bushing can ensure maintenance-free maintenance or lubrication of the pivot bearing, for example using graphite as a material of the bearing bushing.
  • the invention can be used for any type of electric vehicle that is operated with batteries that need to be recharged.
  • Fig. 6 is a cross-sectional view of the contact device from below;
  • the contact device comprises a contact unit carrier 11 with contact units 12, 13, 14, 15, 16, 17 and 18.
  • the contact units 12 to 16 have a contact element 19 and the contact units 17 and 18 each have a contact element 20.
  • the contact elements 19 and 20 protrude at different heights relative to a surface 21 of the contact unit carrier 11 facing the charging contact device, with the contact elements 19 and 20 being shown here in a contact position in which contact surfaces 22 and 23 of the contact elements 19 and 20 are in one common contact level 24 are positioned.
  • the contact elements 19 and 20 are designed with lever arms 25 and 26, respectively, each of which has a rod-shaped extension 27 and 28 with the contact surface 22 and 23, respectively.
  • the contact unit 12 is used to form a grounding contact
  • the contact units 13 to 16 are each used to form a power contact
  • the contact units 17 and 18 are used to form a data contact with charging contacts not shown here.
  • Stops 52 for the respective lever arms 25 and 26 are also formed on the body 29.
  • the stops 52 are designed so that when the contact elements 19 and 20 are in a rest position, they protrude at different heights relative to the surface 21. Included the lever arms 25 and 26 are pressed against the stops 52 with a spring preload via the torsion spring 47.
  • Connecting lugs 53 are provided with holes 54.
  • the connecting cables can be screwed to the holes 54 or the connecting lugs 53.

Abstract

L'invention concerne un dispositif de contact (10) pour un système de charge pour des véhicules électriques, en particulier des voitures de tourisme, des camions, des bus ou similaires, et un système de charge, le système de charge pouvant être agencé sous un véhicule et comprenant un appareil de positionnement, un dispositif de contact de charge et le dispositif de contact ayant un support d'unité de contact (11), le support d'unité de contact ayant au moins deux unités de contact (12, 13, 14, 15, 16, 17, 18), les contacts de charge respectifs du dispositif de contact de charge pouvant être mis en contact avec des éléments de contact des unités de contact pour former une paire de contacts. Au moyen de l'appareil de positionnement, le support d'unité de contact peut être positionné dans une position de contact par rapport au support de contact de charge de sorte qu'une connexion électroconductrice peut être formée entre le véhicule et une station de charge, les au moins deux éléments de contact faisant saillie à différentes hauteurs par rapport à une surface faisant face à l'un des dispositifs de contact de charge du support d'unité de contact, les éléments de contact étant chacun formés avec un bras de levier, le support d'unité de contact ayant un corps (29) qui est formé à partir d'un matériau diélectrique et avec au moins un trou traversant (31) pour les éléments de contact dans la surface faisant face au dispositif de contact de charge, le bras de levier étant monté sur un palier pivotant du corps de façon à pouvoir pivoter par rapport à la surface, les paliers pivotants étant formés sur le corps et étant agencés à différents espacements par rapport à la surface.
