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 transmission 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.
  • the invention is therefore an object of the invention to provide a device for transmitting electrical energy ie from a wall to a hinged about a hinge axis mounted on this wall wings to accomplish a contactless transmission of electrical energy at least with a power, as to charge an electrical energy storage and / or for an electrical consumer is needed. This object is achieved by the reproduced in claim 1 device.
  • the device according to the invention for the transmission of electrical power from a fixed wall into a wing which is hingedly mounted on the wall about a hinge axis therefore has a wall-mountable wall.
  • an attachable to the wing wing part provided on the wall part primary coil and provided on the wing part secondary coil.
  • the primary coil preferably comprises a primary coil winding and a primary coil housing which has ferrimagnetic or ferromagnetic properties, for example containing a ferrimagnetic or ferromagnetic material.
  • the primary coil housing is open on the end face facing the wing part and covers the coil winding at least almost completely on the opposite end face.
  • 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 Sekundärspuiengephase is open on the wall part facing the front side and covers the coil winding on the opposite end face at least almost completely.
  • 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.
  • Such 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 provided on the outer surfaces of the coil housings or else layers with such properties.
  • 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 fastening of the wing to the wall takes place in such a case exclusively with the help of at least two further, conventional bands.
  • the primary and the secondary bobbin 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 also serve to transmit mechanical forces between the wing and the wall and thus at the same time take over the conventional band function.
  • the bolt in order for the bolt, in order to further improve the inductive coupling, also to act as a common core of a transformer formed by means of the primary coil and the secondary coil, it has a length which is covered by the primary coil and by the secondary coil.
  • a sleeve with ferrimagnetic or ferromagnetic properties for example containing a manganese zinc ferrite material.
  • 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, since the unit of bolt with sleeve is particularly easy to produce.
  • at least one of the primary and secondary coils is spring-loaded against the respective other coil in the direction of the hinge axis displaceably mounted 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.
