DESCRIPCIÓN DESCRIPTION
Objeto de la Invención Object of the Invention
La presente invención se refiere a un dispositivo de alimentación eléctrica en mobiliario, que aporta esenciales características de novedad y notables ventajas con respecto a los medios conocidos y utilizados para los mismos fines en el estado actual de la técnica. The present invention relates to a power supply device in furniture, which provides essential novelty characteristics and notable advantages over known means and used for the same purposes in the current state of the art.
Más en particular, la invención propone el desarrollo de un dispositivo capacitado para alimentar fuentes luminosas instaladas en elementos de mobiliario u otras construcciones mediante transferencia inalámbrica de energía por aprovechamiento de un acoplamiento inductivo resonante entre un campo magnético generado por medio de un oscilador y una o más bobinas fijas emisoras asociadas a dicho oscilador, y una bobina receptora asociada a la parte móvil del mueble u otro objeto que incorpora la fuente luminosa. La posición de la bobina receptora es por tanto variable, y el acoplamiento entre bobinas se produce en una o más posiciones cercanas entre ambas, es decir, cuando la bobina móvil se sitúa en una posición cercana y enfrentada a una cualquiera de las bobinas emisoras fijas. More in particular, the invention proposes the development of a device capable of feeding light sources installed in furniture elements or other constructions by means of wireless energy transfer by taking advantage of a resonant inductive coupling between a magnetic field generated by means of an oscillator and one or more fixed emitting coils associated with said oscillator, and a receiving coil associated with the movable part of the furniture or other object that incorporates the light source. The position of the receiving coil is therefore variable, and the coupling between coils occurs in one or more close positions between the two, that is, when the mobile coil is located in a close position and facing any one of the fixed emitting coils. .
El campo de aplicación de la invención se encuentra comprendido dentro del sector industrial dedicado a la construcción y montaje de dispositivos de transferencia inalámbrica de energía.
Antecedentes y Sumario de la Invención The scope of the invention is within the industrial sector dedicated to the construction and assembly of wireless energy transfer devices. Background and Summary of the Invention
La electrificación de elementos equipados con medios de iluminación y dotados de una cierta movilidad, ya sea por deslizamiento o ya sea por abatimiento, como ocurre por ejemplo en ciertos elementos de mobiliario que son móviles con respecto a una porción de estructura fija, ha presentado siempre una serie de inconvenientes que hasta la fecha no han sido completamente resueltos. Asi, en la práctica, cuando la conexión eléctrica con el medio de iluminación del elemento móvil se realiza por medio de un cable extensible, se da con frecuencia la circunstancia desfavorable de que al desplazarse el elemento móvil, el cable de conexión puede verse sometido a esfuerzos derivados de tensiones, situaciones de cizallado, etc., que acaban produciendo el corte u otra interrupción del conector eléctrico, perdiendo con ello la funcionalidad de iluminación asociada a dicho elemento móvil. The electrification of elements equipped with lighting means and provided with a certain mobility, either by sliding or by abatement, as occurs for example in certain furniture elements that are mobile with respect to a fixed structure portion, has always presented a series of inconveniences that to date have not been completely resolved. Thus, in practice, when the electrical connection with the lighting element of the mobile element is carried out by means of an extensible cable, the unfavorable circumstance often occurs that when the mobile element moves, the connection cable can be subjected to stresses derived from stresses, shear situations, etc., that end up causing the cut or other interruption of the electrical connector, thereby losing the lighting functionality associated with said mobile element.
En otros casos, cuando la conexión eléctrica entre la alimentación y el medio emisor de luz incorporado en el elemento móvil se realiza a través de piezas metálicas o de pistas conductoras a lo largo de las cuales se desplazan los contactos correspondientes del elemento móvil, tanto las piezas metálicas como las pistas electrificadas representan riesgos adicionales asociados a posibles descargas para el usuario, aparte del inconveniente de que debido a los esfuerzos que se originan durante el uso, las pistas electrificadas acaban adquiriendo holguras entre las zonas respectivas de contacto, perdiéndose la continuidad eléctrica en muchos puntos del recorrido, con el consiguiente apagado de los medios luminosos al pasar por los puntos de corte mencionados.
En un intento de resolver los problemas mencionados anteriormente, se ha propuesto también en el estado de la técnica el hecho de que la alimentación eléctrica se realice a través de una o más baterías o de algún tipo de célula de energía. Esta solución no es tampoco aplicable en la mayor parte de los casos debido al agotamiento de la batería o de la célula de energía en períodos de tiempo relativamente cortos. In other cases, when the electrical connection between the power supply and the light emitting means incorporated in the mobile element is made through metal parts or conductive tracks along which the corresponding contacts of the mobile element are displaced, both the Metal parts such as electrified tracks represent additional risks associated with possible discharges for the user, apart from the inconvenience that due to the efforts that originate during use, the electrified tracks end up gaining gaps between the respective contact areas, losing electrical continuity in many points of the route, with the consequent shutdown of the luminous means when passing through the mentioned cut-off points. In an attempt to solve the aforementioned problems, it has also been proposed in the state of the art that the power is supplied through one or more batteries or some type of energy cell. This solution is also not applicable in most cases due to the depletion of the battery or the energy cell in relatively short periods of time.
Está claro que los medios actualmente en uso para alimentar eléctricamente cualquier dispositivo emisor de luz montado en un elemento móvil, tal como en una pieza de mobiliario u otra estructura similar, presentan inconvenientes que es necesario solventar. It is clear that the means currently in use to electrically power any light emitting device mounted on a mobile element, such as a piece of furniture or other similar structure, have drawbacks that need to be solved.
Teniendo en cuenta la situación planteada en lo que antecede, la presente invención se ha propuesto como objetivo principal el desarrollo y construcción de un dispositivo de alimentación eléctrica inalámbrica, con el que se resuelvan favorablemente los problemas de la técnica actual . Taking into account the situation outlined above, the present invention has been proposed as the main objective the development and construction of a wireless power supply device, with which the problems of the current technique are favorably resolved.
En esencia, la propuesta de la presente invención se centra en el hecho de que la alimentación eléctrica al medio emisor de luz incorporado en el elemento móvil de la estructura de mobiliario o similar se proporciona de forma inalámbrica, es decir, sin contacto físico ni conexión eléctrica directa entre la fuente de alimentación y el medio emisor de luz. Para ello, el dispositivo está diseñado de modo que la parte fija del mueble u otra estructura está dotada de uno o más medios de generación de un campo electromagnético, que denominaremos bobinas emisoras, ubicadas en una o más posiciones previamente determinadas y seleccionadas de acuerdo con el recorrido o
desplazamiento seguido por el elemento móvil de la estructura de mobiliario. A su vez, dicho elemento móvil incluye un medio receptor materializado en una bobina montada en el propio elemento móvil y que por tanto se desplaza conjuntamente con este último, de tal manera que al llegar a posiciones enfrentadas a las ocupadas por la(s) bobina (s) emisora (s) y verse por tanto afectada por el campo magnético generado por una cualquiera de las bobinas emisoras, genera una tensión eléctrica entre sus extremos que es aplicada al medio de iluminación incorporado en el elemento móvil, provocándose el encendido de este último. En cualquier otra posición del elemento en la que la bobina receptora no se vea afectada por las lineas de campo de la(s) bobina (s) emisora (s), el medio emisor de luz permanecerá apagado al no recibir alimentación eléctrica desde la bobina receptora, o bien al recibir una alimentación eléctrica insuficiente para el encendido de dicho medio emisor de luz. In essence, the proposal of the present invention focuses on the fact that the power supply to the light emitting means incorporated in the mobile element of the furniture structure or the like is provided wirelessly, that is, without physical contact or connection Direct electric between the power supply and the light emitting medium. For this, the device is designed so that the fixed part of the furniture or other structure is provided with one or more means of generating an electromagnetic field, which we will call emitting coils, located in one or more previously determined positions and selected according to the tour or displacement followed by the mobile element of the furniture structure. In turn, said mobile element includes a receiving means materialized in a coil mounted on the mobile element itself and therefore moves together with the latter, so that when it reaches positions facing those occupied by the coil (s) (s) emitter (s) and therefore being affected by the magnetic field generated by any one of the emitting coils, generates an electrical voltage between its ends that is applied to the lighting medium incorporated in the mobile element, causing the ignition of this latest. In any other position of the element in which the receiving coil is not affected by the field lines of the emitting coil (s), the light emitting means will remain off when no power is received from the coil receiver, or when receiving an insufficient power supply for the lighting of said light emitting means.
El dispositivo de la invención ha previsto la particularidad de que tanto los emisores montados en la porción fija del mobiliario u otra estructura cualquiera, como el receptor montado en el elemento móvil del mobiliario u otra estructura cualquiera, constituyan elementos resonantes sintonizados a la misma frecuencia para lograr una generación óptima de energía en la condición de bobinas acopladas. The device of the invention has provided the particularity that both the emitters mounted on the fixed portion of the furniture or any other structure, such as the receiver mounted on the movable element of the furniture or any other structure, constitute resonant elements tuned to the same frequency for achieve optimum power generation in the condition of coupled coils.
Como medios complementarios funcionales, el dispositivo de la invención incluye, en relación con la parte fija del mobiliario u otra estructura cualquiera, un oscilador para la generación de una señal de frecuencia predeterminada, y un amplificador para amplificar la señal generada por dicho oscilador con anterioridad a ser
alimentada a las medios emisores. Complementariamente, en relación con el elemento móvil del mobiliario u otra estructura cualquiera, la invención ha previsto que la señal generada en los medios receptores cuando se acoplan con los emisores, alimente a un rectificador de tensión cuya salida regulada alimenta directamente al medio emisor de luz. As functional complementary means, the device of the invention includes, in relation to the fixed part of the furniture or any other structure, an oscillator for the generation of a predetermined frequency signal, and an amplifier for amplifying the signal generated by said oscillator previously To be fed to the emitting media. In addition, in relation to the movable element of the furniture or any other structure, the invention has provided that the signal generated in the receiving means when coupled with the emitters, feeds a voltage rectifier whose regulated output feeds directly to the light emitting means .
Como se comprenderá, el dispositivo propuesto por la invención constituyen un medio de alimentación eléctrica para un dispositivo emisor de luz montado en un elemento que se mueve con respecto a otra parte fija de una estructura, con el que se solucionan los problemas existentes en el estado actual de la técnica al producir tal alimentación eléctrica de forma inalámbrica. As will be understood, the device proposed by the invention constitutes a power supply means for a light emitting device mounted on an element that moves with respect to another fixed part of a structure, with which the problems existing in the state are solved current technique to produce such power wirelessly.

Descripción de una Forma de Realización Preferida Description of a Preferred Embodiment
Tal y como se ha mencionado en lo que antecede, la descripción detallada de la forma de realización preferida del objeto de la invención, va a ser llevada a cabo en lo que sigue con la ayuda de los dibujos anexos, a través de los cuales se utilizan las mismas referencias numéricas para designar las partes iguales o equivalentes. Asi, atendiendo en primer lugar a la Figura 1 de los dibujos, se puede apreciar una representación esquemática de una versión básica de una primera realización de dispositivo de alimentación eléctrica inalámbrica, aplicado tal y como se viene comentando a lo largo de la presente descripción, a
título de ejemplo ilustrativo y no limitativo, a una estructura de mobiliario, en la que existe una porción fija, materializada en el dibujo por el bloque identificado con la referencia numérica 1, y una porción móvil identificada con la referencia numérica 2, y capacitada para desplazarse a lo largo de la porción fija 1 entre límites preestablecidos. La porción fija incluye los medios emisores, compuestos por un dispositivo oscilador 3 de tipo conocido, diseñado para que oscile a una frecuencia determina y en el que se ha incorporado un amplificador para potenciar la señal generada por el oscilador, y un medio emisor que incluye una bobina identificada con la referencia numérica 5, encargada de generar el campo magnético en un determinado ámbito de influencia, y conectada eléctricamente a la salida del amplificador incluido en el bloque oscilador 3 por medio de una conexión eléctrica convencional indicada ilustrativamente con la referencia numérica 7. As mentioned above, the detailed description of the preferred embodiment of the object of the invention will be carried out in the following with the help of the attached drawings, through which they use the same numerical references to designate the same or equivalent parts. Thus, in the first place according to Figure 1 of the drawings, a schematic representation of a basic version of a first embodiment of a wireless power supply device can be seen, applied as discussed throughout the present description, to illustrative and non-limiting example title, to a furniture structure, in which there is a fixed portion, embodied in the drawing by the block identified with the numerical reference 1, and a mobile portion identified with the numerical reference 2, and capable of move along the fixed portion 1 between preset limits. The fixed portion includes the emitting means, composed of an oscillating device 3 of known type, designed to oscillate at a determined frequency and in which an amplifier has been incorporated to boost the signal generated by the oscillator, and an emitting means that includes a coil identified with the numerical reference 5, responsible for generating the magnetic field in a given sphere of influence, and electrically connected to the output of the amplifier included in the oscillator block 3 by means of a conventional electrical connection indicated illustratively with the numerical reference 7 .
Por su parte, el elemento móvil 2 está vinculado a la porción fija 1 por medio de algún de elemento que permite su movimiento relativo con respecto a la porción fija, por ejemplo un movimiento de desplazamiento o incluso de abatimiento, e incluye un medio receptor estructurado en torno a una bobina receptora identificada con la referencia numérica 6 en la Figura 1, conectada eléctricamente a un medio emisor de luz 4 a través de un medio de conexión convencional identificado mediante la referencia numérica 8. La bobina receptora 6 se mueve conjuntamente con el elemento 2 constitutivo de la porción móvil de la estructura, de manera que podrá ocupar posiciones muy variadas con respecto a la bobina emisora 5, pero de tal modo que cuando la bobina receptora 6 ocupa una posición tal que cae dentro del campo magnético generado por la
bobina emisora 5 (es decir, una posición más o menos enfrentada a la ocupada por la bobina emisora 5) , las lineas de campo magnético cortan a dicha bobina 6, generando una tensión eléctrica entre sus extremos que se aprovecha para la alimentación de la fuente de luz 4, permitiendo que esta última se ilumine. On the other hand, the movable element 2 is linked to the fixed portion 1 by means of some of the element that allows its relative movement with respect to the fixed portion, for example a movement of displacement or even abatement, and includes a structured receiving means around a receiving coil identified with the numerical reference 6 in Figure 1, electrically connected to a light emitting means 4 through a conventional connection means identified by the numerical reference 8. The receiving coil 6 moves together with the element 2 constituting the movable portion of the structure, so that it may occupy very varied positions with respect to the emitting coil 5, but in such a way that when the receiving coil 6 occupies a position such that it falls within the magnetic field generated by the emitting coil 5 (that is, a position more or less facing that occupied by the emitting coil 5), the magnetic field lines cut said coil 6, generating an electrical voltage between its ends that is used to supply the source of light 4, allowing the latter to illuminate.
Con preferencia, la bobina receptora 6 está asociada a un dispositivo rectificador de tensión que proporciona una tensión regulada de salida con la que se alimenta a dicha fuente de luz 4. Preferably, the receiving coil 6 is associated with a voltage rectifying device that provides a regulated output voltage with which it is fed to said light source 4.
Haciendo ahora referencia a la Figura 2 de los dibujos, se muestra esquemáticamente una disposición equivalente a la mostrada en la Figura 1 que se acaba de describir, pero con un diseño tal que, a diferencia con esta última, muestra una multiplicidad de medios emisores materializados mediante varias bobinas 5 que ocupan una multiplicidad de posiciones a lo largo de posiciones enfrentadas al recorrido que va a seguir la bobina receptora 6 durante su desplazamiento conjunto con la porción móvil 2 de la estructura de mobiliario. De ese modo, un usuario puede seleccionar la posición del elemento móvil 2 en la que se ilumine la fuente de luz 4 y que resulte más adecuada a efectos de iluminación en cada momento . Referring now to Figure 2 of the drawings, an arrangement is shown schematically equivalent to that shown in Figure 1 just described, but with a design such that, unlike the latter, it shows a multiplicity of materialized emitting means by means of several coils 5 that occupy a multiplicity of positions along positions facing the path that the receiving coil 6 will follow during its joint movement with the movable portion 2 of the furniture structure. In this way, a user can select the position of the mobile element 2 in which the light source 4 is illuminated and which is more suitable for lighting purposes at any time.
La Figura 3 es una representación esquemática de un ejemplo de realización del dispositivo de la invención equiparable a la versión de la Figura 1, pero en el que la porción móvil 2 de la estructura de mobiliario soporta un medio de información 9 en sustitución de la fuente de luz 4. El resto de los componentes son exactamente iguales que los comentados para la Figura 1, por lo que no van a ser descritos de nuevo.
Con esta disposición, un usuario puede tener acceso a un elemento informativo cualquiera (por ejemplo, una pantalla o un visualizador) , en el que recibir informaciones sobre cualquier materia. En la realización de la Figura 3 solamente se ha incluido una bobina emisora 5 incorporada en la porción fija 1 y una bobina receptora 6 incorporada en la porción móvil 2 sin contacto físico entre ambas, pero esta situación corresponde de nuevo solamente con un ejemplo ilustrativo, dado que la porción fija 1 puede incluir una multiplicidad de medios emisores, tal como las bobinas 5 ubicadas en una multiplicidad de posiciones, de tal modo que el elemento informativo 9 pueda presentar las informaciones en una multiplicidad de posiciones durante el recorrido de la porción móvil 2, seleccionables a voluntad por el usuario. Figure 3 is a schematic representation of an exemplary embodiment of the device of the invention comparable to the version of Figure 1, but in which the movable portion 2 of the furniture structure supports an information medium 9 replacing the source of light 4. The rest of the components are exactly the same as those mentioned in Figure 1, so they will not be described again. With this arrangement, a user can have access to any informative element (for example, a screen or a display), in which to receive information on any subject. In the embodiment of Figure 3, only one transmitter coil 5 incorporated in the fixed portion 1 and one receiver coil 6 incorporated in the mobile portion 2 without physical contact between them have been included, but this situation again corresponds only to an illustrative example, since the fixed portion 1 may include a multiplicity of emitting means, such as the coils 5 located in a multiplicity of positions, such that the information element 9 can present the information in a multiplicity of positions during the travel of the mobile portion 2, selectable at will by the user.
Tal y como se ha mencionado en lo que antecede, tanto los medios emisores como los medios receptores descritos en lo que antecede constituyen circuitos resonantes sintonizados a la misma frecuencia, a efectos de un óptimo rendimiento de transferencia energética desde los emisores hasta los receptores. As mentioned above, both the emitting means and the receiving means described above constitute resonant circuits tuned to the same frequency, for the purpose of optimum energy transfer performance from the emitters to the receivers.
