Definitions

  • the invention relates to a device for transmitting electrical power from a wall to a hinged about a hinge axis hinged to this wall wings.
  • Such doors increasingly include safety or comfort enhancing devices powered by electrical energy.
  • these devices are connected via flexible cables to an external power source.
  • a band with a built-in transformer for contactless energy transfer known.
  • This band comprises a primary coil arranged in a frame band part and a secondary coil arranged in a leaf band part.
  • the magnetic coupling of the secondary coil to the primary coil which are spaced apart in the direction of the hinge axis, serves a coil passing through both iron core, which is formed by a hinge pin.
  • a device for inductive transmission of electrical energy between a body and a vehicle door is known from US 5,156,074 JP 201 057744 known.
  • the invention has for its object to provide a device for transmitting electrical energy from a wall to a hinge axis hingedly mounted on this wall wings to accomplish a contactless transmission of electrical energy at least with a power as they are for charging an electrical Energy storage and / or for an electrical consumer is needed.
  • the device according to the invention for transmitting electrical power from a fixed wall into a hinge hinged to the wall about a hinge axis therefore has a wall-mountable wall portion, a wing portion attachable to the wing, a primary coil provided on the wall portion, and one on the wing portion provided secondary coil on.
  • the primary coil comprises a primary coil winding and a primary coil housing having ferrimagnetic or ferromagnetic properties, for example containing a ferrimagnetic or ferromagnetic material.
  • the primary coil housing is open at the end face facing the wing part and covers the coil winding at least almost completely on the opposite end side.
  • the secondary coil comprises a secondary coil winding and a secondary coil housing having ferrimagnetic or ferromagnetic properties, for example comprising a ferrimagnetic or a ferromagnetic material.
  • the secondary coil housing is open on the end facing the wall part and covers the coil winding on the opposite end face at least almost completely.
  • At least one of the primary and secondary coils is spring-loaded against the respective other coil in the direction of the hinge axis displaceable in the wall or the wing part. Due to this measure it is ensured that the mutually facing end faces of the two coils are always in direct contact. This is of particular importance, since it has surprisingly been found that even with an existing bolt with sleeve already small gaps lead to a significant deterioration of the power transmission from the primary to the secondary coil.
  • a primary coil housing and / or a secondary housing is particularly preferred, which has an inner, cylindrical circumferential surface, around which the primary coil winding or the secondary coil winding is wound.
  • the primary coil housing and / or the secondary coil housing comprises an outer lateral surface which is concentric with the inner circumferential surface is arranged.
  • the coil windings are then protected surrounded by the inner and outer lateral surfaces and the closed end faces.
  • the primary coil housing and / or the secondary coil housing are preferably each formed in one piece from a ferrimagnetic and / or ferromagnetic particles containing plastic.
  • a housing is characterized in particular by its magnetic flux conducting and by its inductive coupling of the coil improving properties.
  • such a housing can readily assume sliding bearing tasks, if it is a bearing material in the plastic used.
  • the ferrimagnetic and / or ferromagnetic particles may consist of different materials.
  • the choice of materials depends essentially on the frequency of the primary voltage. If this is in the range of about 50 kHz, then the use of manganese-zinc-ferrite material has led to good coupling results.
  • the coil housings may include on their outsides electrically conductive shields. This reduces the risk of external electromagnetic fields adversely affecting transmission. It is also prevented that electromagnetic waves are radiated by the inductive transmission and, for example, can disturb radio-operated devices in the vicinity of the device.
  • the shield may comprise electrically conductive layers or layers with such properties provided on the outer surfaces of the coil housings.
  • layer is here to be understood a material layer firmly connected to the respective outer surface, wherein “layer” means a self-supporting configuration or position, for example in the form of a shell.
  • the primary coil winding and the secondary coil winding therefore preferably consist of high-frequency stranded wire.
  • the device according to the invention can be designed such that it serves exclusively for the transmission of electrical energy from a wall to a wing hinged about a hinge axis on this wall and not for the transmission of mechanical forces.
  • the actual attachment of the wing to the wall takes place in such a case exclusively with the help of at least two other conventional bands.
  • the primary and the secondary coil body can then be solid.
  • the primary and secondary coil housings each include an opening extending approximately concentrically with the inner lateral surface in the direction of the hinge axis, through which a hinge bolt defining the hinge axis can be inserted.
  • the device can then serve in addition to the power transmission and the transmission of mechanical forces between the wing and wall and thus at the same time take over the conventional band function.
  • the bolt In order for the bolt to continue to act to enhance inductive coupling as well as a common core of a transformer formed by the primary and secondary coils, it has a sleeve along the length covered by the primary and secondary coils with ferrimagnetic or ferromagnetic properties, for example containing a manganese-zinc-ferrite material on. Their length is preferably as closely as possible to the length covered by the primary and secondary coils, adapted to avoid losses.
  • the sleeve can be pushed onto the bolt. However, it is preferred to provide the sleeve in a concentric with the longitudinal axis of the bolt recess. It is then - particularly preferably - made of a plastic material with ferrimagnetic or ferromagnetic properties having particles, as the unit of bolt with sleeve is particularly easy to produce.
  • the in the FIGS. 1 to 5 as a whole with 100 designated device is designed as a so-called three-piece tape. It comprises an upper wall part 1 and a lower wall part 2. Both parts 1, 2 are spaced apart in the direction of a hinge axis S.
  • a wing part 3 is arranged between the upper and the lower wall part 1, 2, a wing part 3 is arranged.
  • the upper and lower wall parts 1, 2 each comprise a wall hinge part 4, 4 'and a wall fastening part 5, 5'.

  • the diameter of the radial projections 13 interconnecting circle is adapted to the inner diameter of the bolt receptacles 8, 8 ', 9 such that the bearing bushes 11, 11', 12 engage clearance in the respective bolt receptacle.
  • annular end portions 14 are formed, which protrude radially slightly beyond the radial projections 13 , They rest in a correspondingly dimensioned radial extension 15 of the respective bolt receptacle 8, 8 ', 9 and thus close the bolt receptacles to the outside against the ingress of contaminants.

  • the lower end of the lower wall part 2 forms a bearing plate 17 whose dimensions correspond to the end portions 14 and which is inserted into a radial extension 15 of the lower wall portion.
  • the length of the bearing bush 11 ' corresponds almost to the length of the bolt receptacle 8' of the lower wall part 2, whereas the bushings 11, 12 are formed only about half as long as the bolt receptacle 8 of the upper wall portion 1 and the pin receptacle 9 of the wing portion 3.
  • a primary coil 19 and a secondary coil 20 are used in the remaining space of the bolt receptacles 8, 9.

  • the bobbins 23, 24 have at their mutually facing end sides in each case a closed outer end wall 25, 26, which is in each case interrupted by a central through hole 48, 48 'for the passage of the hinge pin.
  • Of the end walls 25, 26 extend concentrically to the hinge axis S in the opposite direction in each case an inner shell wall 27, 28 and in each case an outer jacket wall 29, 30.
  • the bobbin 23, 24 are open ,
