Detaillierte Beschreibung der ErfindungDetailed description of the invention

Fig. 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Möbelplatte 10 mit einer Oberseite 11 und einer Unterseite 12. An der Oberseite 11 der Möbelplatte ist ein elektrisches Gerät 50, beispielsweise ein Smartphone abgelegt. Fig. 1 shows a perspective view of a furniture panel 10 according to the invention with a top 11 and a bottom 12. At the top 11 of the furniture panel is an electrical device 50, such as a smartphone stored.

An der Unterseite 12 der Möbelplatte ist eine Aussparung 20 vorgesehen, in der elektronische Komponenten einer Ladeeinheit angeordnet werden. Mit der Ladeeinheit wird elektrische Energie drahtlos an das an der Oberseite der Möbelplatte abgelegte elektrische Gerät 50 übertragen werden, um etwa einen Akkumulator des elektrischen Gerätes aufzuladen. Die elektronischen Komponenten der Ladeeinheit können in einem Gehäuse 60 angeordnet sein, um die Integration der elektronischen Komponenten in die Möbelplatte 10 zu vereinfachen, weil die Integration durch einfaches Einsetzen des Gehäuses in die Aussparung 20 erfolgen kann. Das Gehäuse 60 ist zudem vorgesehen, die Stabilität der Möbelplatte im Bereich der Aussparung 20 zu erhöhen.On the underside 12 of the furniture panel, a recess 20 is provided, are arranged in the electronic components of a loading unit. With the charging unit, electrical energy will be transmitted wirelessly to the electrical device 50 stored at the top of the furniture panel, in order to charge approximately an accumulator of the electrical device. The electronic components of the charging unit can be arranged in a housing 60 in order to simplify the integration of the electronic components in the furniture panel 10, because the integration can be carried out by simply inserting the housing into the recess 20. The housing 60 is also provided to increase the stability of the furniture plate in the region of the recess 20.

Die Aussparung 20 bzw. das Gehäuse 60 sind hier im Wesentlichen quaderförmig ausgestaltet. Alternativ können die Aussparungen 20 und das Gehäuse 60 beispielsweise auch zylinderförmig, sechseckig, achteckig oder dergleichen ausgestaltet sein.The recess 20 and the housing 60 are configured substantially parallelepipedic here. Alternatively, the recesses 20 and the housing 60 may be configured, for example, also cylindrical, hexagonal, octagonal or the like.

An der Unterseite des Gehäuses 60 ist ein Daten- und/oder Stromkabel vorgesehen bzw. angeschlossen, um die in dem Gehäuse 60 angeordneten elektronischen Komponenten mit Energie zu versorgen bzw. einen Datenaustausch zu ermöglichen. Alternativ kann das Daten- und/oder Stromkabel 90 auch über einen Kabelkanal bzw. Kabelschacht von einer Seitenwandung der Möbelplatte zu dem Gehäuse 60 geführt werden.At the bottom of the housing 60, a data and / or power cable is provided or connected to provide power to the electronic components arranged in the housing 60 or to allow a data exchange. Alternatively, the data and / or power cable 90 can also be routed via a cable duct or cable duct from a side wall of the furniture panel to the housing 60.

Bei der in Fig. 1 gezeigten Ausgestaltung einer erfindungsgemäßen Möbelplatte ist das Gehäuse an der Oberseite 11 der Möbelplatte 10 nicht sichtbar, sodass die Oberseite 11 der Möbelplatte optisch keinen Unterschied zur Oberseite einer herkömmlichen Möbelplatte aufweist. Dies hat den Vorteil, dass, sofern kein elektrisches Gerät 50 zum Zwecke des Aufladens oberhalb der in dem Gehäuse 60 angeordneten elektronischen Komponenten auf der Oberseite 11 der Möbelplatte 10 abgelegt ist, die gesamte Oberseite 11 der Möbelplatte für andere Zwecke genutzt werden kann, ohne das Steckdosen oder andere Steckereinrichtungen die Nutzung der Möbelplatte beeinträchtigen.At the in Fig. 1 shown embodiment of a furniture panel according to the invention, the housing on the top 11 of the furniture panel 10 is not visible, so that the top 11 of the furniture panel visually has no difference to the top of a conventional furniture panel. This has the advantage that, if no electrical device 50 is stored for the purpose of charging above the arranged in the housing 60 electronic components on the top 11 of the furniture panel 10, the entire top 11 of the furniture panel can be used for other purposes without the Sockets or other connector devices affect the use of the furniture panel.

Die Möbelplatte kann aus Holz, einem stabilen Kunststoff, etwa Plexiglas, aus Glas, aus Keramik, aus Stein oder dergleichen gefertigt sein. Wichtig ist jedoch, dass die Möbelplatte 10 im Bereich des Gehäuses 60 möglichst wenig, vorzugsweise kein metallisches Material aufweist, um die drahtlose Energieübertragung zwischen der Ladeeinheit in dem Gehäuse 60 und dem elektronischen Gerät 50 nicht zu beeinträchtigen.The furniture panel may be made of wood, a stable plastic, such as Plexiglas, glass, ceramic, stone or the like. It is important, however, that the furniture panel 10 in the region of the housing 60 as little, preferably no metallic material, so as not to affect the wireless energy transfer between the charging unit in the housing 60 and the electronic device 50.

Vorteilhaft ist es, an der Oberseite 11 der Möbelplatte 10 eine Markierung vorzusehen, welche die Position der in der Möbelplatte 10 integrierten elektronischen Komponente 30 bzw. des in der Möbelplatte integrierten Gehäuses 60 anzeigt. Die Markierung kann beispielsweise mit einer Klebefolie oder dergleichen realisiert werden. Zu Markierung kann jede Technik verwendet werden, welche geeignet ist, die Position der elektronischen Komponente 30 bzw. Gehäuses 60 optisch sichtbar zu machen.It is advantageous to provide a mark on the upper side 11 of the furniture panel 10 which indicates the position of the electronic component 30 integrated in the furniture panel 10 or of the housing 60 integrated in the furniture panel. The marking can be realized for example with an adhesive film or the like. Any technique suitable for making the position of the electronic component 30 or housing 60 optically visible can be used for marking.

Die Möbelplatte 10 kann eine Tischplatte, eine Schreibtischplatte, eine Tischplatte für einen Konferenztisch, eine Küchenarbeitsplatte oder ein Regalboden, etwa für ein Bücherregal sein. Die Möbelplatte 10 kann aber auch eine obere Abdeckplatte eines Schrankes oder eines Rollcontainers sein. Die Möbelplatte kann aber auch als Ablagefläche in einem Fahrzeuginnenraum genutzt werden. Beispielsweise kann die Möbelplatte als Armauflage ausgestaltet sein, oder in das Armaturenbrett integriert sein. Beispielsweise kann die in die Armauflage integrierte elektronische Komponente genutzt werden, ein dort abgelegtes Gerät, etwa ein Smartphone, aufzuladen oder den Zündmechanismus des Fahrzeuges freizugeben, nachdem sich das Smartphone erfolgreich gegenüber der elektronischen Komponente authentifiziert hat.The furniture panel 10 may be a table top, a desk top, a table top for a conference table, a kitchen worktop, or a shelf, such as a bookshelf. The furniture panel 10 may also be an upper cover plate of a cabinet or a roll container. The furniture panel can also be used as a storage space in a vehicle interior. For example, the furniture panel may be configured as an armrest, or integrated into the dashboard. For example, the electronic component integrated in the armrest can be used to charge a device stored there, for example a smartphone, or to release the ignition mechanism of the vehicle after the smartphone has successfully authenticated against the electronic component.

In einer besonderen Ausgestaltung der Erfindung kann die Möbelplatte 10 auch vorgesehen sein in eine Wand integriert zu werden, etwa um die in dem Gehäuse angeordneten elektronischen Komponenten als elektrischen Türöffner zu nutzen. Mit Hilfe eines Smartphones, welches an die Oberfläche 11 angelegt werden kann, kann die in dem Gehäuse 60 angeordnete elektronische Komponente eine Zutrittsberechtigung verifizieren, indem zwischen der elektronischen Komponente und dem Smartphone ein Datenaustausch stattfindet, und den Zutritt freigeben.In a particular embodiment of the invention, the furniture panel 10 may also be provided to be integrated into a wall, such as to use the arranged in the housing electronic components as electric door opener. With the aid of a smartphone, which can be applied to the surface 11, the electronic component arranged in the housing 60 can verify an access authorization by exchanging data between the electronic component and the smartphone, and release the access.

Fig. 2 zeigt eine Schnittansicht entlang der Schnittachse A-A der in Fig. 1 gezeigten Möbelplatte 10. Fig. 2 shows a sectional view along the section axis AA of in Fig. 1 shown furniture panel 10th

Deutlich erkennbar ist hier die Tiefe der Aussparung 20 an der Unterseite 12 der Möbelplatte 10, welche geringer ist, als die Dicke der Möbelplatte selbst. In dem Bereich der Aussparung 20 weist die Möbelplatte 10 eine Dicke d auf.Clearly visible here is the depth of the recess 20 on the underside 12 of the furniture panel 10, which is smaller than the thickness of the furniture panel itself. In the region of the recess 20, the furniture panel 10 has a thickness d.

Erfindungsgemäß werden in der Aussparung 20 bzw. in dem Gehäuse 60 elektronische Komponenten angeordnet, welche eine Energieübertragung zu dem elektrischen Gerät 50 auf induktiver Basis abwickeln. Um eine reibungslose Energieübertragung zu gewährleisten sollte die Dicke d einen bestimmten Maximalwert nicht überschreiten. Vorteilhaft ist es, wenn die Dicke d einen Wert zwischen 1 mm und 10 mm beträgt. Versuche haben gezeigt, dass eine Dicke d zwischen 2 mm und 5 mm besonders vorteilhaft ist.According to the invention 60 electronic components are arranged in the recess 20 and in the housing, which handle an energy transfer to the electrical device 50 on an inductive basis. To ensure a smooth energy transfer to ensure the thickness d should not exceed a certain maximum value. It is advantageous if the thickness d is between 1 mm and 10 mm. Experiments have shown that a thickness d between 2 mm and 5 mm is particularly advantageous.

Gezeigt ist in Fig. 2 die Dicke d zwischen der Oberseite 11 der Möbelplatte und der Oberseite bzw. der oberen Abdeckung 61 des Gehäuses 60. In einer konkreten Realisierung der erfindungsgemäßen Möbelplatte ist die Dicke d der Möbelplatte im Bereich des Gehäuses 60 so zu wählen, dass d dem Abstand zwischen einer Primärspule der elektronischen Komponente in dem Gehäuse 60 und einer Sekundärspule in dem elektrischen Gerät 50 entspricht, wie etwa mit Bezug auf Fig. 3 oder Fig. 4 gezeigt.Shown is in Fig. 2 the thickness d between the top 11 of the furniture panel and the top or the top cover 61 of the housing 60. In a concrete realization of the furniture panel according to the invention, the thickness d of the furniture panel in the region of the housing 60 to be chosen so that d the distance between a Primary coil of the electronic component in the housing 60 and a secondary coil in the electrical device 50 corresponds, as with reference to FIG. 3 or FIG. 4 shown.

Fig. 3 zeigt einen Schnitt durch eine erfindungsgemäße Möbelplatte, an dessen Oberseite 11 ein elektrisches Gerät 50, etwa ein Smartphone, abgelegt ist. Fig. 3 shows a section through a furniture panel according to the invention, on the upper side 11 of an electrical device 50, such as a smartphone, is stored.

Das elektrische Gerät 50 weist eine Sekundärspule 35 auf, über welche die Energieübertragung auf induktiver Basis abgewickelt wird. An der Unterseite 12 der Möbelplatte 10 ist in einer Aussparung ein Gehäuse 60 integriert, welches hier flächenbündig mit der Unterseite 12 der Möbelplatte 10 abschließt. In dem Gehäuse 60 sind die elektronischen Komponenten 30 einer induktiven Ladeeinheit angeordnet. Die elektronischen Komponenten können bspw. eine Control Unit CU, eine Power Conversion Unit PCU und eine System Unit SU umfassen, welche in geeigneter Weise miteinander gekoppelt sind. An der Power Conversion Unit PCU ist eine Primärspule 31 angeordnet bzw. angeschlossen, welche mit der Sekundärspule 35 des elektrischen Gerätes 50 derart zusammenwirkt, dass über die Primärspule 31 und die Sekundärspule 35 die Energieübertragung abgewickelt werden kann. In einer besonderen Ausgestaltung der Erfindung können auch mehrere Primärspulen 31 vorgesehen sein. Eine konkrete Anordnung mehrerer Primärspulen 31 wird mit Bezug auf Fig. 6b näher erläutert.The electrical device 50 has a secondary coil 35, via which the energy transmission is handled on an inductive basis. On the underside 12 of the furniture panel 10, a housing 60 is integrated in a recess, which is flush with the underside 12 of the furniture panel 10 here. In the housing 60, the electronic components 30 of an inductive charging unit are arranged. The electronic components may include, for example, a control unit CU, a power conversion unit PCU and a system unit SU, which are suitably coupled to one another. At the power conversion unit PCU a primary coil 31 is arranged or connected, which interacts with the secondary coil 35 of the electrical device 50 in such a way that the energy transmission can be processed via the primary coil 31 and the secondary coil 35. In a particular embodiment of the invention, a plurality of primary coils 31 may be provided. A concrete arrangement of a plurality of primary coils 31 will be described with reference to FIG Fig. 6b explained in more detail.

Das Gehäuse 60 kann beispielsweise mit Befestigungsschrauben 80 mit der Möbelplatte 10 verbunden werden. Die Unterseite des Gehäuses 60 kann als Deckel ausgestaltet sein, um jederzeit Zugang zu den elektronischen Komponenten 30 zu erhalten.The housing 60 can be connected, for example with fastening screws 80 with the furniture panel 10. The underside of the housing 60 may be configured as a lid to gain access to the electronic components 30 at all times.

In Fig. 3 ist nunmehr der Abstand d zwischen der Primärspule 31 und der Sekundärspule 35 gezeigt, welcher vorzugsweise zwischen 1 mm und 5 mm beträgt. Bei entsprechender Leistung der Ladeeinheit 30 kann der Abstand d auch größer als 5 mm gewählt werden.In Fig. 3 now the distance d between the primary coil 31 and the secondary coil 35 is shown, which is preferably between 1 mm and 5 mm. With a corresponding performance of the loading unit 30, the distance d can also be greater than 5 mm.

Erfindungsgemäß weißt die Oberseite bzw. die obere Abdeckung 61 des Gehäuses 60 ein stabiles Material auf, um die Stabilität der Möbelplatte im Bereich der Aussparung zu erhöhen. Dies ist insbesondere dann vorteilhaft, wenn die Möbelplatte 10 aus einem weniger stabilen Material, etwa Holz gefertigt ist und der vorgegebene Abstand d zwischen den beiden Spulen dazu führt, dass der Abstand zwischen der Oberseite 11 der Möbelplatte und der Oberseite 61 des Gehäuses besonders klein ist. Die stabile Oberseite bzw. obere Abdeckung 61 des Gehäuses 60 verhindert, dass die Möbelplatte im Bereich der Aussparung durchbrechen kann. Um die Energieübertragung zwischen den beiden Spulen nicht zu beeinträchtigen ist die Oberseite bzw. obere Abdeckung 61 des Gehäuses 60 aus einem nichtmetallischen Material gefertigt. Die Abdeckung 61 des Gehäuses 60 kann etwa aus Plexiglas gefertigt sein. Die Seitenwandungen und/oder die Unterseite 62 des Gehäuses 60 können hingegen aus einem metallischem Material, etwa Aluminium oder Stahl gefertigt sein.According to the invention, the upper side or the upper cover 61 of the housing 60 has a stable material in order to increase the stability of the furniture panel in the region of the recess. This is particularly advantageous if the furniture panel 10 is made of a less stable material, such as wood and the predetermined distance d between the two coils causes the distance between the top 11 of the furniture panel and the top 61 of the housing is particularly small , The stable top or top cover 61 of the housing 60 prevents the furniture panel can break in the region of the recess. In order not to interfere with the energy transfer between the two coils, the top cover 61 of the housing 60 is made of a non-metallic material. The cover 61 of the housing 60 may be made of Plexiglas. The side walls and / or the bottom 62 of the housing 60, however, may be made of a metallic material, such as aluminum or steel.

Fig. 4 zeigt eine alternative Ausgestaltung eines in eine Möbelplatte integrierten Gehäuses 60 mit darin angeordneten elektronischen Komponenten 30 einer Ladeeinheit. Fig. 4 shows an alternative embodiment of an integrated housing in a furniture panel 60 with therein disposed electronic components 30 a loading unit.

Im Unterschied zu der in Fig. 3 gezeigten Ausführungsform ist die Primärspule 31 außerhalb des Gehäuses 60 und an der Abdeckung 61 des Gehäuses 60 angeordnet, sodass bei Einhaltung des Maximalabstandes d zwischen der Primärspule 31 und der Sekundärspule 35 der Abstand zwischen der Oberseite 11 der Möbelplatte 10 und der oberen Abdeckung 61 des Gehäuses 60 vergrößert werden kann, was eine stärkere Ausgestaltung der Möbelplatte im Bereich der Aussparung 20 ermöglicht.Unlike the in Fig. 3 In the embodiment shown, the primary coil 31 is arranged outside the housing 60 and on the cover 61 of the housing 60. so that the distance between the upper side 11 of the furniture panel 10 and the upper cover 61 of the housing 60 can be increased while maintaining the maximum distance d between the primary coil 31 and the secondary coil 35, which allows a stronger configuration of the furniture panel in the region of the recess 20.

Bei der in Fig. 4 gezeigten Ausgestaltung einer erfindungsgemäßen Möbelplatte kann auch die Oberseite bzw. die obere Abdeckung 61 des Gehäuses 60 aus einem metallischen Material gefertigt sein, weil in diesem Fall die obere Abdeckung 61 des Gehäuses 60 nicht zwischen der Sekundärspule 35 und der Primärspule 31 angeordnet ist. Dadurch kann ein besonders stabiles Gehäuse 60 bereitgestellt werden, welches besonders positiv zur Stabilität der Möbelplatte im Bereich der Aussparung 20 beiträgt. Letztlich muss bei dieser Ausgestaltung der erfindungsgemäßen Möbelplatte in der Aussparung 20 lediglich eine weitere Aussparung vorgesehen werden, in welcher die Primärspule 31 Platz findet. Weil die Primärspule nur eine sehr geringe Dicke aufweist (vgl. Fig. 6a) weist diese zusätzliche Aussparung ebenfalls nur eine sehr geringe Tiefe auf, was die Stabilität der Möbelplatte im Bereich der Aussparung 20 nur unwesentlich beeinträchtigt. Die obere Abdeckung 61 des Gehäuses 60 und die außerhalb des Gehäuses angeordnete Primärspule 31 liegen vorzugsweise formschlüssig an der Unterseite der Möbelplatte (d.h. in der Aussparung 20) an.At the in Fig. 4 shown embodiment of a furniture panel according to the invention, the top or the top cover 61 of the housing 60 may be made of a metallic material, because in this case the top cover 61 of the housing 60 is not disposed between the secondary coil 35 and the primary coil 31. As a result, a particularly stable housing 60 can be provided, which contributes particularly positively to the stability of the furniture panel in the region of the recess 20. Finally, in this embodiment of the furniture panel according to the invention in the recess 20 only a further recess must be provided, in which the primary coil 31 finds room. Because the primary coil has only a very small thickness (see. Fig. 6a ), this additional recess also only a very small depth, which affects the stability of the furniture panel in the region of the recess 20 only slightly. The upper cover 61 of the housing 60 and arranged outside the housing primary coil 31 are preferably form-fitting manner on the underside of the furniture panel (ie in the recess 20).

Fig. 5 zeigt eine weitere Ausgestaltung einer erfindungsgemäßen Möbelplatte 10, bei der in der an der Unterseite vorgesehenen Aussparung 20 ein Gehäuse 60 mit hier nicht gezeigten elektronischen Komponenten angeordnet ist, wobei das Gehäuse 60 teilweise an der Unterseite 12 der Möbelplatte 10 hervorsteht. Diese Ausführungsform der erfindungsgemäßen Möbelplatte wird vorzugsweise dann gewählt, wenn die Arbeitsplatte an sich eine besonders geringe Dicke aufweist, welche nicht ausreicht das gesamte Gehäuse aufzunehmen. Vorteilhafterweise wird die Höhe des Gehäuses 60 jedoch so gewählt, dass das Gehäuse an der Unterseite mit der Unterseite 12 der Möbelplatte flächenbündig abschließt. Fig. 5 shows a further embodiment of a furniture panel 10 according to the invention, in which in the recess provided on the underside 20, a housing 60 is arranged with electronic components not shown here, wherein the housing 60 protrudes partially on the underside 12 of the furniture panel 10. This embodiment of the furniture panel according to the invention is preferably selected when the worktop has a particularly small thickness in itself, which is not sufficient to accommodate the entire housing. Advantageously, however, the height of the housing 60 is selected so that the housing is flush with the bottom 12 of the furniture panel at the bottom.

Fig. 6a zeigt eine vorteilhafte Ausgestaltung einer Primärspule 31. Die Primärspule 31 ist hier als drahtgewickelte Spule ausgestaltet, welche eine im Wesentlichen ringförmige Form aufweist und einen Außendurchmesser dA von etwa 30 mm bis 60 mm, einen Innendurchmesser dI von etwa 15 mm bis 25 mm und eine Dicke dS von etwa 1,5 mm bis 2,5 mm aufweist. Vorteilhaft ist es, wenn der Außendurchmesser dA zwischen 40 mm und 45 mm, der Innendurchmesser dI zwischen 19 mm und 21 mm und die Dicke dS zwischen 2 mm und 2,2 mm beträgt. Bei der in Fig. 4 gezeigten Ausgestaltung der erfindungsgemäßen Möbelplatte muss lediglich eine zusätzliche zylinderförmige Aussparung für die Primarspule 31 vorgesehen werden, welche eine Tiefe von etwa 1,5 mm bis 2,5 mm aufweist und einen Durchmesser aufweist, welcher im Wesentlichen dem Außendurchmesser dA der Primärspule entspricht. Fig. 6a shows an advantageous embodiment of a primary coil 31. The primary coil 31 is here designed as a wire wound coil having a substantially annular shape and an outer diameter d A of about 30 mm to 60 mm, an inner diameter d I of about 15 mm to 25 mm and has a thickness d S of about 1.5 mm to 2.5 mm. It is advantageous if the outer diameter d A between 40 mm and 45 mm, the inner diameter d I between 19 mm and 21 mm and the thickness d S is between 2 mm and 2.2 mm. At the in Fig. 4 shown embodiment of the furniture panel according to the invention, only an additional cylindrical recess for the primary coil 31 has to be provided, which has a depth of about 1.5 mm to 2.5 mm and has a diameter which substantially corresponds to the outer diameter d A of the primary coil.

Die Primärspule 31 weißt einen Ferrit- bzw. Magnetkern 32 auf, dessen Höhe im Wesentlichen der Dicke dS der Primärspule 31 entspricht.The primary coil 31 has a ferrite or magnetic core 32 whose height substantially corresponds to the thickness d S of the primary coil 31.

Fig. 6b zeigt ein Spulen-Array, welches eine Anzahl von nebeneinander angeordneten und sich teilweise überlappenden Spulen 31 aufweist. Dadurch kann der wirksame Bereich für eine Energieübertragung zwischen den Primärspulen 31 und einer Sekundärspule 35 eines elektrischen Gerätes vergrößert werden. Zudem ist es möglich, die elektronischen Komponenten so auszugestalten, dass diese detektierten können, gegenüber welcher Primarspule 31 sich die Sekundärspule 35 aktuell befindet. Das Spulen-Array kann entweder innerhalb des Gehäuses 60 angeordnet werden, wie bspw. mit Bezug auf Fig. 3 gezeigt, oder außerhalb des Gehäuses 60 angeordnet werden, wie bspw. mit Bezug auf Fig. 4 gezeigt. Fig. 6b shows a coil array having a number of juxtaposed and partially overlapping coils 31. Thereby, the effective range for energy transfer between the primary coils 31 and a secondary coil 35 of an electrical device can be increased. In addition, it is possible to configure the electronic components in such a way that they can detect against which primary coil 31 the secondary coil 35 is currently located. The coil array may be disposed either within the housing 60, such as with reference to FIG Fig. 3 shown, or disposed outside of the housing 60, such as with reference to Fig. 4 shown.

Die in Fig. 6a gezeigte Spule bzw. das in Fig. 6b gezeigt Spulen-Array kann in einer Ausgestaltung der Erfindung in einem quaderförmigen oder zylinderförmigen Block aus Epoxidharz eingelassen sein, wobei nur die Anschlüsse der Spule bzw. des Spulen-Arrays nach außen geführt sind. Der so gebildete stabile Spulenblock kann dann unabhängig von dem Gehäuse 60, in dem die übrigen elektronischen Komponenten der Ladeeinheit angeordnet sind, in die Aussparung 20 eingebracht werden. Nach dem Einbringen des Spulenblockes in die Aussparung 20 können dann die Anschlüsse der Spule bzw. des Spulen-Arrays mit entsprechenden Anschlüssen des Gehäuses verbunden werden und das Gehäuse in die Aussparung 20 eingesetzt werden.In the Fig. 6a shown coil or in Fig. 6b shown coil array may be embedded in an embodiment of the invention in a cuboid or cylindrical block of epoxy resin, wherein only the terminals of the coil or the coil array are guided to the outside. The thus formed stable coil block can then be introduced into the recess 20 independently of the housing 60, in which the remaining electronic components of the charging unit are arranged. After the introduction of the coil block into the recess 20, the terminals of the coil or of the coil array can then be connected to corresponding terminals of the housing and the housing can be inserted into the recess 20.

Dies hat den Vorteil, dass eine erfindungsgemäße Möbelplatte hergestellt werden kann, in die ein Spulenblock integriert ist, ohne auch die übrigen elektronischen Komponenten der Ladeeinheit integrieren zu müssen. Der Spulenblock kann mittels geeigneter Befestigungsmittel in der Aussparung befestigt werden. Die übrigen elektronischen Komponenten der Ladeeinheit können dann vom den Nutzer der Möbelplatte nachgerüstet werden, um etwa eine auf ein bestimmtes elektrisches Gerät 50 angepasste Ladeeinheit zu integrieren.This has the advantage that a furniture panel according to the invention can be produced, in which a coil block is integrated without having to integrate the other electronic components of the charging unit. The coil block can be secured in the recess by means of suitable fastening means. The remaining electronic components of the charging unit can then be retrofitted by the user of the furniture panel to integrate about a customized to a particular electrical device 50 charging unit.

In einer alternativen Ausgestaltung der Erfindung kann die Spule auch an der Unterseite der Möbelplatte (d.h. in der Aussparung) aufgedruckt sein, etwa mit einem elektrischen leitfähigen Lack, z.B. Silberlack.In an alternative embodiment of the invention, the coil may also be printed on the underside of the furniture panel (i.e., in the recess), such as with an electrically conductive lacquer, e.g. Silver paint.

Fig. 7 zeigt einen Schnitt durch eine erfindungsgemäße Möbelplatte, wobei wie in Fig. 4 gezeigt, die Primärspule 31 und der Ferrit- bzw. Magnetkern 32 außerhalb des Gehäuses 60 und an der Oberseite 61 des Gehäuses 60 angeordnet sind. Fig. 7 shows a section through a furniture panel according to the invention, wherein as in Fig. 4 shown, the primary coil 31 and the ferrite or magnetic core 32 are arranged outside of the housing 60 and on the upper side 61 of the housing 60.

Die Primärspule 31 und der Ferrit- bzw. Magnetkern 32 sind von einem stabilen Material 70 umgeben bzw. in ein stabiles Material 70 eingelassen. Das stabile Material 70 kann bspw. ein Kunststoff oder ein glasfaserverstärkter Kunststoff sein. Als vorteilhaft für das stabile Material 70 hat sich Duraplast erwiesen. Alternativ können die Primärspule 31 und der Magnetkern 32 auch in Epoxidharz eingelassen werden. Das die Spule und den Magnetkern umgebende Material bildet einen quader- oder zylinderförmigen Block (Spulenblock) mit einer im Wesentlichen flachen Oberseite und Unterseite.The primary coil 31 and the ferrite or magnetic core 32 are surrounded by a stable material 70 or embedded in a stable material 70. The stable material 70 may be, for example, a plastic or a glass fiber reinforced plastic. Duraplast has proved to be advantageous for the stable material 70. Alternatively, the primary coil 31 and the magnetic core 32 may also be embedded in epoxy resin. The material surrounding the coil and the magnetic core forms a cuboid or cylindrical block (coil block) with a substantially flat upper side and underside.

Diese Ausgestaltung hat den Vorteil, dass die Primärspule 31 und der Magnetkern 32 einerseits vor äußeren Einflüssen geschützt sind. Andererseits wird durch das stabile Material 70 ein die Primärspule 31 und den Magnetkern 32 umgebender stabiler und fester Mantel gebildet. Die Oberseite dieses stabilen Mantels liegt formschlüssig an der Unterseite des dünnen Bereichs der Tischplatte an. Die Unterseite dieses stabilen Mantels liegt formschlüssig an der Abdeckung 61 des Gehäuses 60 an. Der Spulenblock trägt damit positiv zu Stabilität der Tischplatte im Bereich der Aussparung 20 bei.This embodiment has the advantage that the primary coil 31 and the magnetic core 32 are protected on the one hand against external influences. On the other hand, a stable and solid shell surrounding the primary coil 31 and the magnetic core 32 is formed by the stable material 70. The top of this stable shell is positively against the underside of the thin area of the table top. The underside of this stable shell is positively against the cover 61 of the housing 60 at. The coil block thus contributes positively to stability of the table top in the region of the recess 20.

Fig. 8 zeigt eine alternative Ausgestaltung einer erfindungsgemäßen Möbelplatte 10, wobei das Gehäuse 60 an der Oberseite 11 der Möbelplatte sichtbar ist. Das Gehäuse 60 weist hier im Wesentlichen die gleiche Höhe auf wie die Dicke der Möbelplatte 10. Die Oberseite bzw. die obere Abdeckung 61 des Gehäuses 60 ist flächenbündig zur Oberseite 11 der Möbelplatte angeordnet. Die obere Abdeckung 61 des Gehäuses 60 kann aus einem transparenten, semi-transparenten oder nicht-transparenten und nicht-metallischem Material sein.

The housing 60 here has substantially the same height as the thickness of the furniture panel 10. The top or the top cover 61 of the housing 60 is arranged flush with the top 11 of the furniture panel. The top cover 61 of the housing 60 may be made of a transparent, semi-transparent or non-transparent and non-metallic material.

In der in Fig. 8 gezeigten Ausgestaltung ist das Gehäuse 60 nicht mit Befestigungsschrauben an der Platte befestigt, sondern mittels eines Klebstoffes 80. Die Verwendung von Klebstoff 80 ist dann vorteilhaft, wenn sich das Material der Möbelplatte für die Herstellung von Bohrlöchern nicht eignet.In the in Fig. 8 As shown, the housing 60 is not fastened to the plate with fastening screws, but by means of an adhesive 80. The use of adhesive 80 is advantageous if the material of the furniture plate is not suitable for the production of boreholes.

Fig. 9 zeigt eine konkrete Realisierung einer erfindungsgemäßen Möbelplatte in einer Schnittansicht, wobei das Gehäuse 60 im Wesentlichen zylinderförmig ausgestaltet ist. Fig. 9 shows a concrete realization of a furniture panel according to the invention in a sectional view, wherein the housing 60 is designed substantially cylindrical.

Die Aussparung 20 ist ebenfalls im Wesentlichen zylinderförmig ausgestaltet und weist hier ungefähr auf etwa der halben Höhe eine umlaufende Stufe auf, an der Vorsprünge des Gehäuses 60 mittels Befestigungsschrauben 80 befestigt werden. Die Vorsprünge können als umlaufender Ring ausgestaltet sein. Die untere Abdeckung 62 des Gehäuses ist hier mittels Befestigungsschrauben an dem zylinderförmigen Gehäuseteil befestigt.The recess 20 is also designed substantially cylindrical and here has approximately at about half the height of a circumferential step, are attached to the projections of the housing 60 by means of fastening screws 80. The projections may be configured as a circumferential ring. The lower cover 62 of the housing is fastened here by means of fastening screws on the cylindrical housing part.

Im oberen Bereich des Gehäuses 60 sind die Primärspule 31 und der Magnetkern 32 angeordnet. Der Magnetkern 32 ist hier so ausgestaltet, dass er in die Primärspule 31 hineinragt und an der Unterseite über die Primärspule 31 hinausragt. Unterhalb der Primärspule 31 bzw. unterhalb des Magnetkerns 32 ist eine Schirmplatte 33 angeordnet und mittels Befestigungsschrauben an dem Gehäuse 60 befestigt. Die Schirmplatte 33 dient zur Abschirmung des elektromagnetischen Feldes gegen die unterhalb der Schirmplatte 33 angeordneten, hier nicht gezeigten, elektrischen Komponenten der Ladeeinrichtung. Die Schrimplatte 33 kann beispielsweise Aluminium aufweisen. Ferner weist die Schirmplatte 33 an einem Randbereichen einen Durchbruch, etwa in Form eines Langloches auf, durch welchen die elektrischen Anschlüsse für die Spule 31 durchgeführt werden.In the upper region of the housing 60, the primary coil 31 and the magnetic core 32 are arranged. The magnetic core 32 is designed here such that it projects into the primary coil 31 and projects beyond the primary coil 31 on the underside. Below the primary coil 31 and below the magnetic core 32, a shield plate 33 is arranged and fixed by means of fastening screws to the housing 60. The shield plate 33 serves to shield the electromagnetic field against the arranged below the shield plate 33, not shown here, electrical components of the charger. The Schrimplatte 33 may for example comprise aluminum. Further, the shield plate 33 at an edge regions on an opening, such as in the form of a slot through which the electrical connections for the coil 31 are performed.

Gemäß der in Fig. 9 gezeigten Ausführungsform ist an der Oberseite des Gehäuses 60 eine Abdeckung 61 vorgesehen, welche ein besonders stabiles Material aufweist, um die Möbelplatte im Bereich der Spule bzw. des Magnetkerns zu stabilisieren. Die Abdeckung 31 weist ein nichtmetallisches Material auf, um die induktive Energieübertragung zwischen der Primärspule 31 und einer Sekundärspule 35 eines elektrischen Gerätes 50 nicht zu beeinträchtigen. Auf die Abdeckung 61 kann auch verzichtet werden, sodass die Primärspule 31 und der Magnetkern 32 näher an die Oberseite 11 der Möbelplatte 10 heranrücken können. Bei Verzicht einer oberen Abdeckung 61 ist es vorteilhaft, die Primärspule 31 und den Magnetkern 32 in ein stabiles Material, etwa Epoxidharz einzulassen, bzw. die Hohlräume damit aufzufüllen.According to the in Fig. 9 In the embodiment shown, a cover 61 is provided on the upper side of the housing 60 which has a particularly stable material in order to stabilize the furniture panel in the area of the coil or of the magnetic core. The cover 31 comprises a non-metallic material in order not to interfere with the inductive energy transfer between the primary coil 31 and a secondary coil 35 of an electrical device 50. On the cover 61 can also be dispensed with, so that the primary coil 31 and the magnetic core 32 can move closer to the top 11 of the furniture panel 10. In the absence of an upper cover 61, it is advantageous for the primary coil 31 and the magnetic core 32 to be embedded in a stable material, for example epoxy resin, or for the cavities to be filled with it.

Anstellte der in Fig. 9 gezeigten Befestigungsschrauben 80 können auch sogenannte Clips-Verschlüsse vorgesehen werden, welche ein besonders einfaches und schnelles Lösen des Gehäuses 60 von der Platte ermöglichen. Dadurch wird ein einfaches Austauschen des Gehäuses samt der elektronischen Komponenten oder die Entnahme des Gehäuses, etwa zum Zwecke einer Reparatur vereinfacht.Start the in Fig. 9 also shown so-called clips-closures can be provided, which allow a particularly simple and quick release of the housing 60 of the plate. This will be a simple replacement of the housing together with the electronic components or the removal of the housing, such as for the purpose of repair easier.

Gezeigt ist in Fig. 9 ebenfalls der Abstand d zwischen der Primärspule 31 und der Sekundärspule 35. Versuche haben ergeben, dass insbesondere bei Verwendung einer stabilen Abdeckung 61 die Dicke der Möbelplatte im Bereich der Abdeckung 61 lediglich 1 mm betragen kann, ohne dass die Möbelplatte in diesem Bereich beschädigt wird. Die zylinderförmige Gehäusewandung kann aus einem Metall gefertigt sein, sodass die obere Abdeckung 61 umlaufend auf einem stabilen Gehäuse aufliegt.Shown is in Fig. 9 likewise the distance d between the primary coil 31 and the secondary coil 35. Experiments have shown that, in particular when using a stable cover 61, the thickness of the furniture panel in the region of the cover 61 can be only 1 mm, without the furniture panel being damaged in this area. The cylindrical housing wall may be made of a metal, so that the upper cover 61 rests circumferentially on a stable housing.

Fig. 10 zeigt eine erfindungsgemäße vorteilhafte Weiterbildung eines Gehäuses 60 zur Integration in einer erfindungsgemäßen Möbelplatte. Bereitgestellt werden hier zwei Führungsschienen 100 zwischen denen das Gehäuse 60 relativ zu den Führungsschienen bewegbar angeordnet ist. Die Führungsschienen sind aus einem stabilen Material gefertigt, wobei die Längsführungen der Schienen so ausgestaltet sind, dass ein Bewegen des Gehäuses 60 entlang der Führungsschienen ohne großen Kraftaufwand möglich ist.

Fig. 11 zeigt eine Draufsicht einer erfindungsgemäßen Möbelplatte 10, wobei an der Unterseite der Möbelplatte 10 eine längliche Aussparung 20 vorgesehen ist. In der länglichen Aussparung 20 sind an den Seitenwandung zwei Führungsschienen 100, wie mit Bezug auf Fig. 10 gezeigt, angeordnet, entlang derer das Gehäuse 60 bewegt werden kann, dadurch wird es möglich, den aktiven Bereich, etwa für ein Aufladen eines elektrischen Gerätes durch Veränderung der Position des Gehäuses 60 zu ändern. Fig. 11 shows a plan view of a furniture panel 10 according to the invention, wherein on the underside of the furniture panel 10, an elongated recess 20 is provided. In the elongated recess 20 are on the side wall two guide rails 100, as with reference to Fig. 10 shown, along which the housing 60 can be moved, thereby making it possible to change the active area, such as for charging an electrical device by changing the position of the housing 60.

Anstellte der in Fig. 10 gezeigten Führungsschienen können die Längsführungen auch direkt in den Seitenwandungen der Aussparung 20 hineingefräst werden.Start the in Fig. 10 shown guide rails, the longitudinal guides can also be milled directly into the side walls of the recess 20.

Bei Vorsehen einer Aussparung 20 in der das Gehäuse 60 hin- und herbewegt werden kann, ist es vorteilhaft, an der Unterseite der Möbelplatte im Bereich der Aussparung eine Stabilisierungsplatte einzubringen, um die Möbelplatte in dem Bereich der Aussparung zu stabilisieren.When providing a recess 20 in which the housing 60 can be reciprocated, it is advantageous to introduce a stabilizing plate on the underside of the furniture panel in the region of the recess in order to stabilize the furniture panel in the region of the recess.

Vorstehend ist die erfindungsgemäße Möbelplatte insbesondere in Bezug auf elektronische Komponenten 30 beschrieben worden, welche ausgestaltet sind, eine drahtlose Energieübertragung zwischen den elektronischen Komponenten und einem an der Oberseite der Möbelplatte abgelegten elektrischen Gerätes zu bewerkstelligen.Above the furniture panel according to the invention has been described in particular with respect to electronic components 30 which are designed to accomplish a wireless energy transfer between the electronic components and a stored on the top of the furniture plate electrical device.

Alternativ oder zusätzlich zur drahtlosen Energieübertragung auf induktiver Basis können die elektronischen Komponenten 30 auch ausgestaltet sein eine Datenübertragung, vorzugsweise bidirektionale Datenübertragung zwischen den elektronischen Komponenten 30 und dem elektrischen Gerät abzuwickeln. Die elektronischen Komponenten können hierzu etwa über eine USB-Schnittstelle mit einer Datenverarbeitungseinrichtung gekoppelt sein. Bei einer entsprechenden Anordnung etwa eines Mobiltelefons oder eines Smartphones relativ zu den elektronischen Komponenten 30 kann durch das Smartphone eine Authentifizierung an der Datenverarbeitungseinrichtung vorgenommen werden. Der Zugriff auf die Datenverarbeitungseinrichtung kann dann freigegeben werden, wenn die Authentifizierung erfolgreich war. Ferner kann die Datenübertragung dazu verwendet werden, um nur solche elektrischen Geräte mit Energie zu versorgen, welche sich gegenüber den elektronischen Komponenten 30 erfolgreich authentifizieren. Innerhalb von Unternehmen könnte damit gewährleistet werden, dass nur Firmengeräte aufgeladen werden können, während etwa private Mobiltelefone nicht aufgeladen werden können.As an alternative or in addition to inductive-based wireless energy transmission, the electronic components 30 can also be configured to handle data transmission, preferably bidirectional data transmission between the electronic components 30 and the electrical device. For this purpose, the electronic components can be coupled to a data processing device, for example via a USB interface. In the case of a corresponding arrangement of, for example, a mobile telephone or a smartphone relative to the electronic components 30, an authentication can be performed on the data processing device by the smartphone. The access to the data processing device can be released if the authentication was successful. Further, the data transmission may be used to power only those electrical devices that successfully authenticate to the electronic components 30. Within companies, it could be ensured that only company devices can be charged while, for example, private mobile phones can not be recharged.

Zudem ist es möglich, über die elektronischen Komponenten 30 eine Datensynchronisation zwischen dem elektrischen Gerät 50 und der Datenverarbeitungseinrichtung durchzuführen. Hierfür muss etwa ein Smartphone lediglich auf einem dafür vorgesehenen Bereich eines Schreibtisches abgelegt werden, wobei die Authentifizierung des Smartphones gegenüber der Datenverarbeitungseinrichtung automatisch erfolgt, und die Datensynchronisation bei erfolgreicher Authentifizierung automatisch gestartet wird.In addition, it is possible to perform a data synchronization between the electrical device 50 and the data processing device via the electronic components 30.
