IDENTIFICATION MEANS FOR LOCKING SYSTEM
Description
The invention relates to an identification means for a locking system having a transponder and an antenna, the antenna having a core and a coil wrapped around the core, the core of the antenna having a plurality of dielectric layers which lie one above the other in a sandwich-like manner and have high permeability, and the layers being electrically insulated from one another, and the core of the antenna and the transponder being designed to form a structural unit as a transponder element.
A portable data carrier having a radio-based data communication device is known from WO 2011/091830 A1. Here, an antenna coil having a core is arranged within a carrier substrate. Two shielding structures are arranged on the outer sides of the carrier substrate. However, the data carrier is very complex to assemble with the antenna coil wound around the core.
A label having an RFID chip is known, for example, from WO 2017/159436 A1. In the case of this label, a printed circuit board is shielded from a magnetic body by means of a sealing layer. An antenna coil is wound around the magnetic body and the printed circuit board. However, the power of the antenna is very low.
EP 1 944 827 A2 discloses an antenna which can be used for an RFID tag reading/writing device. For this purpose, an IC can be connected to the antenna by means of printed circuit board wirings and printed circuit board terminals.
US 2007/279300 A1 discloses an antenna assembly for emitting a long-wave wake-up signal. Such an antenna assembly can be used in the interior of a motor vehicle door handle.
US2017/214139 A1 discloses an antenna module having magnetic insulation layers and non-magnetic insulating layers. The magnetic insulation layers contain magnetic ferrite.
WO 2017/159436 A1 discloses an RFID tag having a circuit board. A coil is guided around the circuit board.
2 EP3 767 748
CN 105 229 852 A discloses a coil assembly printed on a film.
JP 2009-130446A discloses a radio transmitter and receiver having a coil and a plate made of magnetic material. Furthermore, two metal plates are arranged parallel to one direction of a magnetic flux on both sides of the coil. This is intended to avoid the shift of a resonant frequency.
The problem addressed by the invention is that of developing an identification means of the type mentioned at the outset in such a way that it can be produced particularly cost-effectively and at the same time has a high mutual inductance and therefore good coupling properties.
According to the invention, this problem is solved in that the dielectric layer has an insulation layer, an adhesive layer, and a ferrite layer arranged between the insulation layer and the adhesive layer.
As a result of this design, an easy to handle subassembly can first be produced with the essential components. Since the core of the antenna has a plurality of dielectric layers that are insulated from one another, undesirable effects such as eddy current losses, among other things, are reliably prevented, whereby the antenna has a high antenna power. The layer-like structure allows the identification means to be produced particularly cost-effectively. Furthermore, at a given thickness of the core, the layer-like structure ensures high mechanical flexibility and thereby a high mechanical resistance to shock or torsional loads.
The identification means is particularly cost-effective because the dielectric layer has an insulation layer, an adhesive layer, and a ferrite layer arranged between the insulation layer and the adhesive layer. Due to this design, the dielectric layer consists of multiple sublayers. As a result, the dielectric layers lying one above the other in a sandwich-like manner each have their own insulation.
In order to further reduce the manufacturing costs of the identification means, according to another advantageous development of the invention, it is expedient if the layer having high permeability is designed as an adhesive film. Such adhesive films can be easily cut or punched out and adhesively bonded one above the other in a sandwich-like manner.
3 EP3 767 748
According to an advantageous development, the identification means has a particularly high stability if a printed circuit board having conductor paths is arranged in parallel on the layers and is part of the structural unit as a transponder element. This design prevents the electrical components and conductor paths from having to be applied directly to the layers. As a result, the coil wires can be placed in a simple manner and the transponder chip can be contacted directly. In this way, cost-effective production is made possible.
According to another advantageous development of the invention, the identification means is particularly compact if the coil of the antenna is wound around the transponder element. The direct connection of the coil of the antenna and the transponder element prevents the need for additional conductor elements and detuning of the resonant frequency caused by these conductor elements.
According to another advantageous development of the invention, mechanical holding of the coil on the transponder element can easily be ensured if the transponder element has a recess for receiving the coil.
According to another advantageous development of the invention, protruding components can be prevented if the recess has a depth which corresponds to the height of the coil.
According to another advantageous development of the invention, mechanical stabilization of the layers by the printed circuit board can be achieved in a simple manner if the printed circuit board and the layers of the core have the same outline.
In order to further simplify the structural design of the identification means, according to another advantageous development of the invention, it is expedient if the transponder is arranged on a first side of the printed circuit board and the layers are arranged on the other side of the printed circuit board.
In order to improve the emission properties of the antenna, according to another advantageous development of the invention, it is expedient if the printed circuit board has at least one further dielectric layer on the side of the transponder. The further dielectric layer can have a central recess for the transponder.
4 EP3 767 748
In order to further reduce the manufacturing costs, according to another advantageous development of the invention, it is expedient if the insulation layer comprises the plastics material PET. The elastic properties of the dielectric layer and thus also of the entire layer system are further improved by an insulation layer designed in this way.
An emission characteristic of the antenna sufficient for identification means can be achieved according to another advantageous development of the invention if the ferrite layer has a thickness of from 0.05 to 0.45 mm. The plastics material layer and the adhesive layer preferably have a thickness of 0.03 to 0.05 mm.
According to another advantageous development of the invention, the identification means can be designed as a key for an electronic lock cylinder of the locking system if the identification means has a plastics housing having a shaft and the transponder element is inserted into the shaft and is fastened in the shaft in a firmly bonded or formfitting manner.
The invention permits numerous embodiments. For further clarification of its basic principle, several of the embodiments are shown in the drawings and described below. In the drawings:
Fig. 1 shows an identification means having a key-shaped plastics housing prior to assembly,
Fig.2 is an enlarged representation of a transponder element of the identification means from Fig. 1,
Fig. 3 — shows a greatly enlarged portion III of the transponder element from Fig. 2,
Fig. 4-8 show further embodiments of the transponder element.
Figure 1 shows an identification means 1 for a locking system (not shown) having a key-shaped plastics housing 2 prior to assembly. The identification means 1 has a transponder element 3 having a transponder 4 and an antenna 5. The plastics housing 2 has a shaft 6 for receiving the transponder element 3 and is key-shaped in design. For assembly, the transponder element 3 can be inserted into the shaft
EP3 767 748 6 and fastened therein by a casting compound or fixed in a formfitting manner. An electronic key for a lock cylinder is thus created.
In an embodiment (not shown), the transponder element 3 can also be integrated in a card, a key chain, or the like, in order to control corresponding locking 5 systems.
Figure 2 is an enlarged representation of the transponder element 3 from figure 1.
The transponder element 3 has a plurality of dielectric layers 7 which lie one above the other in a sandwich-like manner and have high permeability. These layers 7 form a core 8 of the antenna 5. A printed circuit board 9 is arranged on the layers 7. The printed circuit board 9 has the transponder 4 and a plurality of conductor paths 10. The transponder 4 is fastened as a chip on the printed circuit board 9. The printed circuit board 9 can also have further electrical components (not shown). A coil 11 of the antenna 5 is wound around the printed circuit board 9 and the layers 7. For this purpose, the transponder element 3 has a recess 12 in the form of a constriction.
Figure 3 shows, for clarification, greatly enlarged a detail III of the transponder element 3 from figure 2. It can be seen here that the layers 7 consist of a plurality of partial layers. A central partial layer is formed by a dielectric ferrite layer 13. The ferrite layer 13 has an insulation layer 14 made of the plastics material PET on one side, and an adhesive layer 15 on the other side.
Figure 4 shows a transponder element 103, which differs from that from figure 2 only in that a recess 112 leads to a pointed end of the transponder element 103.
As a result, the coil 11 can be wound separately and pushed onto the transponder element 103.
Figure 5 shows a transponder element 203 which differs from that from figure 2 in that the transponder 4 is arranged directly on the layers 7 of the core 8 of the antenna 5. A printed circuit board as in the embodiment according to figure 2 is not required here.
Figure 6 shows a transponder element 303 which differs from that from figure 4 in that the transponder is fastened to the layers 7 of the core 8 of the antenna 5. A
6 EP3 767 748 recess 312 for receiving the coil 11 leads to the pointed end of the transponder element.
Figure 7 shows a transponder element 403, which differs from that from figure 6 only in that a recess 412 for receiving the coil 11 leads to a rounded end of the transponder element 403.
Figure 8 shows a transponder element 503 which differs from that from figure 5 in that the transponder 4 is arranged below the coil 11 of the antenna 5.
