Definitions

  • the invention relates to a system for transmitting electrical power from a wall to a hinged about a hinge axis S 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 hinge pin.
  • the invention is therefore an object of the invention to provide a system 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 to load a electrical energy storage and / or for an electrical consumer is needed.
  • the system according to the invention for transmitting electrical energy from a wall to a wing hinged about a hinge axis to this wall comprises primary electronics which convert a supply voltage into a primary voltage for energizing the primary coil, which is adapted to inductive coupling in the secondary coil To generate secondary voltage, and with a secondary electronics, which converts the secondary voltage into a suitable for an electrical energy storage and / or for an electrical load electrical operating voltage.
  • the electrical energy store may be, for example, an accumulator or a capacitor, in particular an electrolytic capacitor, the power peaks of the electrical consumers and short-term secondary voltage interruptions buffer and smooth the secondary voltage.
  • the supply voltage may be a mains voltage.
  • the spatial dimensions of the primary electronics can be adapted, for example, to the internal volume of a conventional flush-mounted box, in particular when the mains voltage is used as the supply voltage, from which a connection of the output of the primary electronics to the primary coil can take place with the aid of cables drawn through an empty conduit can.
  • the secondary electronics have spatial dimensions that make them suitable for introducing, for example, in a hollow profile of a wing, so that no electronic components are visible on the wing side.
  • the system according to the invention only appears as another band and it does not appear that there is electric power in the wing needing components are located.
  • the primary voltage has a frequency which is at least 20 kHz. This avoids that other components are converted into mechanical vibrations in the audible range by the electromagnetic field generated by the primary coil.
  • the primary frequency is between 50 and 140 kHz. It is then far above the limit of the audible and not yet in such a high frequency range in which must be reckoned with a radiation of radio waves through the leads, which could interfere with the radio in the long wave range.
  • the primary voltage which is applied to the primary coil is preferably at most 48 V. Because of this limitation, on the one hand a minimum power of 500 mW can be transmitted with the aid of the system according to the invention, without the primary coil having a disadvantageous size for the intended purpose, on the other hand Security measures at higher Primary voltages for the protection of persons against electrification would be necessary, are waived, since voltages up to the specified maximum value persons are not dangerous.
  • the primary voltage is between 3.5 and 15 V.
  • a coil designed for this voltage range has again smaller dimensions, so that it is better for accommodating also in a band, which at the same time serves to transmit mechanical forces between the wing and wall or in a device whose optical appearance is that of a conventional band corresponds, is suitable.
  • most consumers provided in one wing operate in this voltage range, so that the same components can be used for the primary coil and the secondary coil, and yet none of the secondary coil downstream of the transformer is required. Alone in this case is a rectification of the induced in the secondary coil AC voltage, since such is not suitable for charging an electrical energy storage.
  • an existing mains voltage or a DC voltage provided by, for example, a power supply is preferably converted accordingly.
  • the primary coil preferably comprises a primary coil winding and a coil body made of a ferromagnetic or ferrimagnetic material, which can at least almost cover the coil winding on the end face facing the wing part and which can be open on the opposite end side and the secondary coil a secondary coil winding and a secondary coil body made of a ferromagnetic or ferrimagnetic material, which on the wall part facing the end face at least almost cover the coil winding and may be open on the opposite end face.
  • a primary coil body and / or a secondary coil body to use which has an inner, cylindrical outer surface around which the primary coil winding and the secondary coil winding is wound.
  • the primary coil body and / or the secondary coil body comprise an outer circumferential surface arranged concentrically to the inner circumferential surface is.
  • the coil winding is then protected surrounded by the inner and outer lateral surface and the closed end face.
  • the primary coil winding and the secondary coil winding preferably consist of high-frequency stranded wire.
  • the system 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 bodies each comprise an opening extending approximately concentrically with the inner lateral surface in the direction of the hinge axis, through which a 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 ferromagnetic or ferrimagnetic properties. 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 ferrite 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 existing bolts with sleeve already small gaps lead to a significant deterioration of the power transmission from the primary to the secondary coil.
  • the coil has a length which is smaller than the outer diameter of its coil housing.
  • the bolt can be mechanically stored over a greater length, so as to achieve the lowest possible specific material load.
  • Tests have shown that a power transmission of at least 500 milliwatts at a primary voltage of 5 V and a primary frequency of about 120 kHz can be achieved if the inductances of the primary coil and the secondary coil are preferably about 30 ⁇ H.
