Definitions

  • the invention relates to a contactless energy and / or data transmission system for a door or window arrangement with at least one frame for a door or a window and at least one wing of the door or window, with at least one transmitter side, in particular the frame associated, induction coil and at least a receiver-side, in particular the wing associated, induction coil.
  • electronic units are provided in the area of the door or window sash.
  • Such an electronic unit may be, for example, a motorized locking device which is locked and unlocked as part of a security system in a time- and / or remotely controlled manner.
  • Another example of the use of electronic units in the area of the wing of doors or windows are displays or other means of identification, which serve for information or for better perception of escape doors, for example.
  • lighting devices are often used in the region of the wing for the aforementioned reasons and to achieve a certain visual appearance of a door or a window.
  • the connection of such electronic units is usually via a cable connection. The power supply for electrical consumers and any data connection are given in this way permanently.
  • connection from the frame to the wing can often be made only from the hinge side, but consumers are often, as in the case of a motorized locking device, also arranged on the wing side of the wing, the wired power supply to the consumer is usually with an increased installation costs connected.
  • the cable is routed outside over the wing. If such a laying method is not desirable for reasons of safety or because of the risk of simple manipulability for safety reasons, the cable can alternatively be installed concealed within the profile of the wing, resulting in a further increased assembly costs.
  • An alternative to the use of the aforementioned connections is the power supply of electrical consumers via an energy store, for example a battery or an accumulator, which is provided together with the consumer in the region of the door or window sash.
  • an energy store for example a battery or an accumulator
  • a remedy to this problem creates a contactless energy and / or data transmission system of the type mentioned, which is based on the principle of induction.
  • An example of such a system is the induction charging of electric toothbrushes.
  • this technology has also been increasingly used in the field of consumer electronics, for example for charging mobile phones or similar devices.
  • the device to be charged is in this case merely introduced into a charging device or placed on a flat charging device and charged its energy storage without a connection via electrically conductive contacts and in particular without the connection of a cable.
  • the transmission of energy and / or data has become known as the so-called Qi standard.
  • the transmission is usually between two coils, which are in fixed coupling to each other, under non-resonant conditions.
  • the coils used are characterized mainly by a flat, but in two dimensions comparatively extensive design. Since with a fixed coupling of the induction coil, the relative position of the transmitter to the receiver coil of great importance for the efficiency of the transmission, the transmitter side often planar arrangements of a plurality of overlapping coils are used, of which each of the ideal position nearest coil selected and is used for the transmission. With typical dimensions of about 40 x 40 mm for a single coil, however, such a system is not suitable for installation in comparatively limited space, as in the case of a door or window arrangement between wing and frame, or makes at least a complex profile machining required.
  • German patent DE 102 46 671 describes the attempt to use an induction-based, non-contact power transmission system in a door from a fixed frame to a movable door leaf.
  • a major problem is always that the inductors used must be brought as close as possible to the existing air gap between the frame and wing to ensure efficient energy transfer, but at the same time a comparatively compact due to the limited space in the edge regions of the frame or the wing , In particular, narrow design of the system is required, which further precludes the performance of such a compound, in particular for energy transmission. This problem is the more pronounced, the greater the gap to be bridged air gap between the transmitter and receiver coil.
  • the above object is achieved in a contactless energy and / or data transmission system according to the preamble of claim 1, characterized in that the transmitter-side and / or the receiver-side induction coil is arranged in each case on an E-profile or as a U-shaped armature core.
  • U-profile and E-profile are usually distinguished, however, in both cases it is a profile of basically similar construction, in which of a common web, at least substantially perpendicular to this and at least substantially protrude parallel to each other limbs.
  • U-profile in some cases, alternatively, a "C-profile”
  • E-profile a profile with at least three legs based on the shape of the letter “E” as " E-profile "is called.
  • E-profile or "E-shaped profile” in the context of the invention, in principle, a profile with more than three legs, ie with a comb-like shape to understand.
  • anchor cores designed as an E-profile or a U-profile allow the magnetic field lines emerging from the end faces of the transmitter-side armature core to enter the end faces of the receiver-side armature core both on the transmitter side and on the receiver side, and thus have an extremely great effect to achieve efficient energy transfer according to the principle of induction.
  • the system can be adapted by the inventive design of the fundamentally E- or U-shaped armature core to the respective installation situation in a simple manner.
  • the inventive design of the fundamentally E- or U-shaped armature core allows a very narrow design of the legs of the armature core, whose end faces even in the case of very limited space, such as very thin-walled doors or windows, close to the gap to be bridged. Since the field lines of the magnetic field generated by the transmitter-side induction coil extend at least substantially within the armature core and thus can be guided, they emerge at least substantially at the end faces in the region of the gap.
  • the transmission system according to the invention is particularly suitable for consumers or, electronic units in the wing with comparatively large power consumption, for example, motorized locking devices with a large, difficult to move mechanics.
  • the efficiency and overall system transferable performance can be further enhanced by a coil arrangement of a plurality of coils on the transmitter and / or receiver sides.
  • a receiver-side resonant circuit with at least one coil and at least one capacitor (capacitance), in particular with adjustable natural frequency (resonant frequency)
  • the resonance frequency of the resonant circuit is preferably tuned to the input frequency of the transmitter-side induction coil or coils.
  • a resonance-capable oscillating circuit can likewise be generated by at least one capacitance connected in parallel with the receiver-side induction coil. By adapting the capacitance, the resonant frequency of this oscillatory system can be adjusted and, in this way, the transmission efficiency further increased. The same applies to the case of a plurality of receiver-side induction coils.
  • the positive effects of the invention are due, in large part, to the ferromagnetic properties of the material used for the armature core.
  • a ferritic sintered material has proven to be particularly advantageous, which, given good ferromagnetic properties, can easily be brought into a form suitable for the respective installation situation.
  • the steering of the magnetic field and the resulting high flux density in the air gap between the transmitter and the receiver part of the system make it possible to bridge comparatively wide gaps, with air not necessarily being solely between the transmitter side and the receiver side Must be part.
  • the magnetic field also penetrates electrically non-conductive materials.
  • the end faces of the armature core therefore need not be exposed, so that the transmitter and / or the receiver-side part of the transmission system according to the invention can also be hidden behind a decorative or insulating layer integrated into the frame or in the wing.
  • an armature core is provided both on the transmitter side and on the receiver side.
  • This is preferably an anchor core in the frame and one on the opposite side in the wing.
  • the two anchor cores are arranged mirror-symmetrically to one another in the frame or in the wing. This means, first of all, that the free ends of the legs of the anchor cores assign each other. It is favorable in this context, in particular, to use a C-shaped on the other side when using a C-shaped armature core on the one hand.
  • the mutually opposite and facing each other anchor cores can have the same dimensions, but this is not required in principle.
  • the distance of the end faces of the anchor cores in the closed state of the door or window assembly is at least 4 mm, in particular at least 8 mm, preferably at least 10 mm. Since it is basically also possible, depending on the installation situation, to have an armature core only on one of the two sides, i. the above-mentioned values apply in this case for the distance of the end face of the transmitter-side armature core to the receiver-side induction coil or the transmitter-side induction coil to the end face of the receiver-side armature core.
  • a high-frequency alternating current is transmitted, whose frequency is preferably between 10 kHz and 250 kHz.
  • the excitation of audible and annoying felt mechanical vibrations is largely prevented, while occurring power losses remain limited to an acceptable level.
  • a receiver-side rectifier circuit in particular with a downstream constant current source, generates a usable direct current from the induced alternating current.
  • Conceivable electrical consumers are for example a motor-operated closing device and / or an identification device for identifying the door or window arrangement.
  • a possible illumination By a possible illumination, the perceptibility of such an identification device is further increased.
  • the total power consumption increases accordingly, so that in this case the high transmission efficiency of the energy and / or data transmission system according to the invention has an advantageous effect.
  • At least one energy store is preferably provided in the door or window wing, in which energy fed in is stored.
  • the actuation of a motor-operated closing device or the lighting or labeling, for example, an escape door permanently guaranteed.
  • the energy store may in particular have at least one rechargeable accumulator.
  • at least one so-called supercapacitor which is a special capacitor with a high capacity of usually more than 1 Farad.
  • a supercapacitor is able to store and release the transmitted energy more quickly.
  • the life of a supercapacitor is also significantly greater than that of a rechargeable battery. This feature is presently particularly advantageous because each opening and closing of the door or the window represents a new switching cycle for the energy storage.
  • An alternative embodiment of the energy store is a system comprising at least one accumulator and at least one supercapacitor. In this way the comparatively high capacity of a rechargeable battery can be combined with the increased switching capacity of a supercapacitor.
  • the risk of failure of the uninterruptible power supply can be easily assessed by a circuit for monitoring the state of charge of the energy storage.
  • information about the state of charge of the energy store can be transmitted via a data connection so that a plurality of door or window arrangements can be correspondingly monitored from a central location.
  • a data transmission may be provided in addition to or instead of an energy transmission.
  • data transmission is realized, for example, by providing a circuit which serves to modulate the generated magnetic field and thus the induced alternating current.
  • electronic units on the door or window wing are controlled based on data from sensors on the same wing. Examples of this are the switching of a lighting device as a function of the ambient brightness measured with a photodiode or the unlocking of a closing device when a person with access rights is detected on a door. While in some cases such control may be realized by a local circuit between the sensor and the electronic unit to be controlled, in other cases it is desirable that control be via a central location such that transmission of the sensor data from the door or door leaf Window arrangement to the control center and a transfer of control data from the control center to the electronic unit on the wing done.
  • a circuit for bidirectional data transmission By means of a circuit for bidirectional data transmission, transmission of data both from the door or window sash and to it via the same contactless energy and / or data transmission system can be realized.
  • a corresponding circuit is preferably provided both on the transmitter and on the receiver side.
  • the reflected power is modulated by a corresponding receiver-side circuit, measured on the transmitter side and correspondingly demodulated. It is understood that such a bidirectional data transmission can not be used exclusively for the transmission of related sensor and control data, but the use of both channels, that is, out-and-back channel, is independently possible.
  • data pertaining to the locking state of a locking device may be transmitted to both a door or window sash to control it, as well as data being transmitted in the reverse direction to read out the locking state of such a locking device.
  • the transmitted data may relate to the opening state of the door or window arrangement.
  • This data can for example be processed by an access control system or evaluated by a central security system. It is also conceivable that by means of control data an electromechanical lock on a spring-loaded door or window sash is remotely released or activated to close the door or the window.
  • the contactless energy and / or data transmission system according to the invention is also suitable for the transmission of data that serve to control an identification device for identifying the door or window arrangement, wherein in particular the control of a lighting device is conceivable.
  • an identification device for identifying the door or window arrangement
  • a lighting device for identifying the door or window arrangement

  • the memory is preferably non-volatile. The stored data are thus still available even after a power failure.
  • the contactless energy and / or data transmission system is used for controlling or operating a motorized closing device
  • the energy and / or data transmission system is arranged at a small distance from the closing device , This results in short distances for the required cable connections between the receiver-side part of the transmission system according to the invention and the locking device. In this way, disadvantages such as further line losses or high assembly costs are avoided or reduced.
  • the contactless energy and / or data transmission system 1 is used in a door assembly 2 with a frame 3 and a wing 4 to realize a contactless connection for the transmission of energy and / or data between the frame 3 and the wing 4.
