DISPOSITIVO ELECTROMECÁNICO PARA ACCIONAMIENTO Y CONTROL ELECTROMECHANICAL DEVICE FOR DRIVING AND CONTROL
DEL DESPLAZAMIENTO DE PARTES MÓVILES DE VEHÍCULOSOF THE DISPLACEMENT OF MOBILE PARTS OF VEHICLES
La presente invención concierne a un dispositivo electromecánico para accionamiento y control del desplazamiento de partes móviles de vehículos, tales como lunas de ventanillas, techos corredizos, asientos, respaldos, etc., el cual comprende un motor, una transmisión y una placa de circuito impreso que integra un circuito electrónico de control del motor, cuya placa de circuito impreso está dispuesta cubriendo al menos en parte una caja de dicha transmisión, quedando los componentes del citado circuito electrónico de control situados dentro de dicha caja, permitiendo con ello una máxima compacidad del conjunto.The present invention concerns an electromechanical device for driving and controlling the movement of moving parts of vehicles, such as window windows, sunroofs, seats, backrests, etc., which comprises an engine, a transmission and a printed circuit board. which integrates an electronic motor control circuit, whose printed circuit board is arranged at least partially covering a box of said transmission, the components of said electronic control circuit located within said box being left, thereby allowing maximum compactness of the set.
Son conocidos en el estado de la técnica los circuitos electrónicos de control con etapa de distribución de potencia y sensor de velocidad y sentido de giro o detector de intensidades consumidas por motor, aplicados a motores destinados a desplazar partes móviles de vehículos.Electronic control circuits with power distribution stage and speed sensor and direction of rotation or detector of intensities consumed by motor, applied to motors intended to move moving parts of vehicles are known in the state of the art.
Por ejemplo, un motor de elevalunas de ventanilla de automóvil requiere, para su buen funcionamiento, un control de paro y arranque en los dos sentidos de giro para una utilización normal, ordenada voluntariamente por un usuario, y un dispositivo de paro automático, o de inversión de sentido de giro, en caso de detectarse de una manera segura un sobreesfuerzo brusco del motor durante una operación de cierre o apertura, cuyo sobreesfuerzo es indicativo de que la luna ha encontrado un obstáculo en su trayectoria. Este paro automático o inversión del sentido de giro del motor tiene gran importancia a efectos de seguridad puesto que con frecuencia tal obstáculo es una parte del cuerpo de una persona o animal doméstico ocupante del vehículo o que desde el exterior esté asomada al interior del vehículo. El accionamiento de otras partes móviles de un vehículo, tales como asientos y respaldos, tiene requerimientos similares a efectos de seguridad para el ocupante. Desde hace años, todas estas funciones se controlan mediante un microprocesador con una o varias memorias asociadas integrado en un circuito de control que incluye una etapa de distribución de potencia al motor y un sensor de efecto Hall o similar para detectar la velocidad y el sentido de giro del árbol del motor. Este circuito de control está dispuesto en una placa de circuito impreso asociada a un conjunto formado por el citado motor y una transmisión, generalmente del tipo de tornillo-sin-fin y corona dentada. Sin embargo, la asociación de una tal placa de circuito impreso al conjunto de motor y transmisión de cada ventanilla, asiento, respaldo o similar, representa un grave problema de espacio debido a la estrecha limitación del espacio disponible en los sitios donde tales dispositivos deben ir alojados, y además la placa de circuito impreso necesita protección para no quedar desprotegida y expuesta a la suciedad, humedad y posibles golpes. Otro inconveniente es la necesidad de incluir un cableado eléctrico entre la placa de circuito impreso y el motor.For example, a car window window motor requires, for proper operation, a stop and start control in both directions of rotation for normal use, voluntarily ordered by a user, and an automatic stop device, or reversal of the direction of rotation, in the event of detecting in a safe way a sudden overexertion of the engine during a closing or opening operation, whose overexertion is indicative that the moon has encountered an obstacle in its trajectory. This automatic stop or reversal of the direction of rotation of the engine is of great importance for safety purposes since such an obstacle is often a part of the body of a person or pet occupying the vehicle or from outside it is peeking inside the vehicle. The actuation of other moving parts of a vehicle, such as seats and backrests, has similar requirements for safety purposes for the occupant. For years, all these functions have been controlled by a microprocessor with one or more associated memories integrated in a control circuit that includes a stage of power distribution to the motor and a Hall effect sensor or similar to detect the speed and direction of turn of motor shaft This control circuit is arranged on a printed circuit board associated with an assembly formed by said motor and a transmission, generally of the screw-end type and toothed crown type. However, the association of such a printed circuit board with the motor and transmission assembly of each window, seat, backrest or the like represents a serious space problem due to the narrow limitation of the space available at the sites where such devices must go housed, and also the printed circuit board needs protection to not be unprotected and exposed to dirt, moisture and possible shocks. Another drawback is the need to include electrical wiring between the printed circuit board and the motor.
La patente WO 91/01060, con prioridad del 11 de julio de 1989, describe un sistema de accionamiento de una ventanilla motorizada en un vehículo. El sistema comprende una unidad de accionamiento dispuesta en una carcasa precintada y conectada a un sensor de velocidad de giro, y es controlable mediante una unidad electrónica de control y regulación. La citada unidad electrónica de control y regulación, la unidad de accionamiento y el sensor de velocidad de giro están dispuestos en una carcasa precintada común. La unidad de control está dispuesta sobre una placa de circuito impreso que se conecta al motor mediante un conector interno de la carcasa. La unidad de accionamiento incluida en la carcasa comprende un motor y una transmisión, estando el árbol de salida del motor provisto de un tornillo-sin-fin que ataca una corona dentada. El sensor de velocidad de giro proporciona una señal a la unidad de control a través de un detector previsto en una zona de la citada placa de circuito impreso que queda próxima al citado árbol. La unidad de control está basada en un microprocesador y tiene una etapa de salida de potencia de accionamiento hacia el motor.WO 91/01060, with priority of July 11, 1989, describes a drive system of a motorized window in a vehicle. The system comprises a drive unit disposed in a sealed housing and connected to a rotation speed sensor, and is controllable by an electronic control and regulation unit. Said electronic control and regulation unit, the drive unit and the rotation speed sensor are arranged in a common sealed housing. The control unit is arranged on a printed circuit board that is connected to the motor through an internal connector of the housing. The drive unit included in the housing comprises a motor and a transmission, the engine output shaft being provided with an endless screw that attacks a toothed crown. The rotation speed sensor provides a signal to the control unit through a detector provided in an area of said printed circuit board that is close to said tree. The control unit is based on a microprocessor and has an output stage of drive power towards the motor.
Aunque este sistema tiene la ventaja de formar un módulo compacto provisto de una carcasa en la que están integrados tanto los elementos electromecánicos como electrónicos, aportando una innegable mejora en cuanto a la protección de la placa de circuito impreso y a la ausencia de cableado entre la placa y el motor, en lo referente a la ocupación de espacio la mejora conseguida es prácticamente nula, debido a que se precisa de una extensión de la carcasa, de dimensiones considerables, con la única finalidad de alojar la citada placa de circuito impreso de la unidad de control.Although this system has the advantage of forming a compact module provided with a housing in which both the electromechanical and electronic elements are integrated, providing an undeniable improvement in the protection of the printed circuit board and the absence of wiring between the board and the engine, in relation to the occupation of space, the improvement achieved is practically null, because an extension of the housing, of considerable dimensions, with the sole purpose of housing the said printed circuit board of the control unit.
La patente EP-A-0474904, presentada el 12 de septiembre de 1990, describe un accionamiento de ventanilla motorizada que utiliza un motor conmutador eléctrico con un circuito de control integrado que usa una placa de circuito unidimensional, la cual incorpora en un lado una parte en la que se disponen los portaescobillas del motor y en otro lado una parte en la que se dispone una base de enchufe para un conector. Las conexiones eléctricas de los componentes de la placa de circuito, las escobillas y los cables con las pistas de la placa de circuito se efectúan mediante un baño de soldadura. El motor tiene una carcasa fijada a una caja que aloja una transmisión reductora de tornillo-sin-fin y corona dentada, cuya caja comprende una prolongación adaptada para alojar la citada placa de circuito.EP-A-0474904, filed on September 12, 1990, describes a motorized window drive that uses an electric switching motor with an integrated control circuit that uses a one-dimensional circuit board, which incorporates on one side a part in which the motor brush holders are arranged and in another part a part in which a plug base for a connector is arranged. The electrical connections of the components of the circuit board, the brushes and the cables with the tracks of the circuit board are made by means of a welding bath. The motor has a housing fixed to a box that houses a screw-worm reduction gear and toothed crown, whose box comprises an extension adapted to accommodate said circuit board.
Esta disposición es muy similar a la de la patente WO 91/01060 discutida anteriormente, y gracias a los portaescobillas montados en la placa de circuito, se elimina incluso un cableado interno entre la placa de circuito y el motor, lo que proporciona simplicidad en el montaje. Sin embargo, la inclusión de la placa de circuito dentro de una prolongación de la caja de la transmisión sigue ocupando un espacio considerable que hace que el conjunto sea difícil de ubicar en los reducidos espacios donde se precisa, tales como en el interior de las puestas del vehículo, debajo de los asientos o dentro de los respaldos de los mismos.This arrangement is very similar to that of WO 91/01060 discussed above, and thanks to the brush holders mounted on the circuit board, even internal wiring between the circuit board and the motor is eliminated, which provides simplicity in the mounting. However, the inclusion of the circuit board within an extension of the transmission case continues to occupy a considerable space that makes the assembly difficult to locate in the small spaces where it is needed, such as inside the stalls. of the vehicle, under the seats or inside the backrests of the same.
A la vista de lo anterior, el objetivo de la presente invención es el de aportar un dispositivo electromecánico para accionamiento y control del desplazamiento de partes móviles de vehículos que sea de diseño muy compacto, de bajo peso, y exento de cableado exterior entre sus elementos componentes.In view of the foregoing, the objective of the present invention is to provide an electromechanical device for driving and controlling the movement of moving parts of vehicles that are of a very compact design, of low weight, and free of external wiring between their elements. components.
Este objetivo se consigue de acuerdo con al presente invención aportando un dispositivo electromecánico para accionamiento y control del desplazamiento de partes móviles de vehículos, del tipo que comprende un motor provisto de una carcasa, cuyo motor acciona una transmisión alojada en una caja provista de al menos una tapa, a cuya caja está fijada dicha carcasa del motor. El motor está conectado a un circuito electrónico de control, los componentes del cual están dispuestos en una única placa de circuito impreso la cual se dispone cerrando al menos en parte la citada caja de dicha transmisión, quedando los diferentes componentes encerrados dentro de la caja, y cada uno dispuesto en un sitio operativamente conveniente. Al exterior de la caja únicamente asoma un conector de alimentación y señales de dicho circuito electrónico integrado en la placa de circuito impreso.This objective is achieved in accordance with the present invention by providing an electromechanical device for driving and controlling the movement of moving parts of vehicles, of the type comprising a motor provided with a housing, whose motor drives a transmission housed in a box provided with at least a cover, to whose box said motor housing is fixed. The motor is connected to an electronic control circuit, the components of which are arranged in a single printed circuit board which is arranged by at least partially closing said transmission case, the different components being enclosed within the box, and each arranged in an operationally convenient place. Only a power and signal connector of said electronic circuit integrated in the printed circuit board appears outside the box.
Según un ejemplo de realización de la invención, dicha placa de circuito impreso es un placa de circuito impreso de una sola cara, la cual forma la citada tapa de la caja, siendo fijada a la misma, por ejemplo, mediante tornillos. Esta solución es adecuado para aquellos casos en los que el circuito electrónico es más simple y en los que las condiciones externas no exigen una especial hermetización de la caja. Sin embargo, se prefiere que dicha placa de circuito impreso sea una placa de circuito impreso de doble cara dispuesta encajada en un rebajo del contorno interior de la abertura de dicha caja. Esta placa de circuito de doble cara queda totalmente cubierta por dicha tapa de la caja, la cual es típicamente metálica, por ejemplo de aluminio moldeado, lo que favorece la disipación del calor generado por el circuito electrónico. Además, la existencia de esta tapa rígida permite una completa hermetización del circuito electrónico y de los elementos electromecánicos dentro de la caja, e incluso permite el precintado de la misma.According to an embodiment of the invention, said printed circuit board is a single-sided printed circuit board, which forms the aforementioned lid of the box, being fixed thereto, for example, by screws. This solution is suitable for those cases in which the electronic circuit is simpler and in which external conditions do not require special sealing of the box. However, it is preferred that said printed circuit board is a double-sided printed circuit board arranged embedded in a recess of the inner contour of the opening of said housing. This double-sided circuit board is completely covered by said box cover, which is typically metallic, for example molded aluminum, which favors the dissipation of heat generated by the electronic circuit. In addition, the existence of this rigid cover allows a complete sealing of the electronic circuit and of the electromechanical elements inside the box, and even allows its sealing.
El hecho de que la placa de circuito impreso sea de doble cara implica que habrá pistas electroconductoras situadas en la cara más exterior de la placa que quedarán enfrentadas a la cara más interior de la tapa metálica. Para evitar posible cortocircuitos debidos al contacto de la tapa metálica con las citadas pistas el citado rebajo donde se encaja la placa de circuito impreso es suficientemente profundo para la misma quede en el interior de la caja distanciada de la tapa, colocándose convenientemente unos pequeños separadores entre placa y tapa. Otra posible solución consiste en disponer dicha placa de circuito impreso de doble cara de manera que quede adosada a la tapa, e interponer una capa de material eléctricamente aislante entre la citada cara más exterior de la placa y la cara más interior de la tapa. Preferiblemente, dicha capa de material eléctricamente aislante es una capa de una resina sintética aplicada directamente sobre dicha cara más exterior de la placa, cubriendo sus pistas y entrepistas.The fact that the printed circuit board is double-sided implies that there will be electroconductive tracks located on the outermost side of the board that will face the innermost face of the metal cover. To avoid possible short circuits due to the contact of the metal cover with the mentioned tracks, the aforementioned recess where the printed circuit board fits is deep enough for it to be inside the box separated from the cover, conveniently placing small spacers between plate and cover. Another possible solution is to arrange said double-sided printed circuit board so that it is attached to the lid, and to interpose a layer of electrically insulating material between said outermost face of the plate and the innermost face of the lid. Preferably, said layer of electrically insulating material is a layer of a resin synthetic applied directly on said outermost face of the plate, covering its tracks and entrepistas.

Haciendo en primer lugar referencia a la Fig. 1 , se muestra el dispositivo electromecánico para accionamiento y control del desplazamiento de partes móviles de vehículos de acuerdo con la presente invención. Tal dispositivo es de especial aplicación en la industria de la automoción para el desplazamiento controlado de partes móviles de un vehículo tales como lunas de ventanillas, techos corredizos, asientos, respaldos, etc. El dispositivo comprende un motor 1 provisto de una carcasa 5, cuyo motor 1 acciona una transmisión 2 alojada en una caja 3 provista de al menos una tapa 4, a cuya caja 3 está fijada dicha carcasa 5 del motor 1. Tal como se ha explicado anteriormente, el motor 1 está conectado a un circuito electrónico de control dispuesto en al menos una placa de circuito impreso 6 asociada al conjunto.These and other features will become more apparent from the following detailed description of some preferred embodiments of the invention, which are provided for illustrative purposes only, and should therefore not be construed in any way as limiting. The following detailed description cited includes references to the accompanying drawings, in which: Fig. 1 is an overall perspective view of the electromechanical device of the present invention; Fig. 2 is a cross-sectional view of the transmission cover and housing assembly including the printed circuit board, according to a first embodiment; Fig. 3 is a bottom perspective view of the printed circuit board constituting the transmission case cover of the electromechanical device of Fig. 1 according to a second embodiment; and Fig. 4 is an exploded top perspective view of the transmission cover and case assembly according to said first embodiment. Referring firstly to Fig. 1, the electromechanical device for driving and controlling the movement of moving parts of vehicles according to the present invention is shown. Such a device is of special application in the automotive industry for the controlled movement of moving parts of a vehicle such as window windows, sunroofs, seats, backrests, etc. The device comprises a motor 1 provided with a housing 5, whose motor 1 drives a transmission 2 housed in a box 3 provided with at least one cover 4, to which case 3 said motor housing 5 is fixed 1. As explained previously, engine 1 is connected to an electronic control circuit arranged in at least one printed circuit board 6 associated with the assembly.
En la Fig. 3 se muestran los componentes del citado circuito electrónico de control, los cuales son básicamente un microprocesador 61 con una o más memorias asociadas, una etapa de distribución de potencia 62, varios condensadores 63 y un sensor de efecto Hall 64. El circuito se completa con un conector 7 situado en un borde de dicha placa de circuito impreso 6. El citado microprocesador contiene un algoritmo de control de los desplazamientos de la correspondiente parte móvil accionada por el dispositivo, incluyendo una función de paro automático o inversión del sentido de giro del motor como medida de seguridad frente a posibles accidentes producidos por la interposición de un objeto o parte del cuerpo de una persona en la trayectoria de dicha parte móvil. Este algoritmo gobierna el motor 1 a través de la etapa de distribución de potencia 62. Las señales de entrada al algoritmo de seguridad provienen del citado sensor de efecto Hall y son indicativas de la velocidad y sentido de giro del motor, y por consiguiente de la velocidad y sentido de los desplazamientos de la parte móvil accionada por dicho motor. Así, el microprocesador conoce las fases e incidencias en los movimientos de la parte móvil correspondiente por la frecuencia de unos pulsos de tensión generados cada vez que un polo magnético asociado al eje rotativo del motor pasa por la proximidad del sensor de efecto Hall.In Fig. 3 the components of said electronic control circuit are shown, which are basically a microprocessor 61 with one or more associated memories, a power distribution stage 62, several capacitors 63 and a Hall effect sensor 64. The The circuit is completed with a connector 7 located on one edge of said printed circuit board 6. The aforementioned microprocessor contains an algorithm for controlling the movements of the corresponding mobile part actuated by the device, including an automatic stop or reverse direction function. of rotation of the engine as a safety measure against possible accidents caused by the interposition of an object or part of a person's body in the trajectory of said moving part. This algorithm governs the motor 1 through the power distribution stage 62. The input signals to the safety algorithm come from said Hall effect sensor and are indicative of the speed and direction of rotation of the motor, and consequently of the speed and direction of the displacements of the mobile part driven by said motor. Thus, the microprocessor knows the phases and incidences in the movements of the corresponding moving part by the frequency of some tension pulses generated each time a magnetic pole associated to the rotating axis of the motor passes through the proximity of the Hall effect sensor.
Los citados componentes del circuito electrónico están dispuestos en una única placa de circuito impreso 6, la cual se dispone cerrando al menos en parte la citada caja 3 de dicha transmisión, quedando los diferentes componentes encerrados dentro de la caja 3 y cada uno dispuesto en un sitio operativamente conveniente, asomando únicamente al exterior de la caja 3 un conector 7 de alimentación y señales de dicho circuito electrónico.The aforementioned components of the electronic circuit are arranged in a single printed circuit board 6, which is arranged by at least partially closing the said box 3 of said transmission, the different components being enclosed within the box 3 and each arranged in a operationally convenient location, only a power connector 7 and signals of said electronic circuit sticking out of the box 3.
En la Fig. 2 se muestra la disposición de la placa de circuito impreso 6 según un primer ejemplo de realización de la invención. En el ejemplo ilustrado, dicha placa de circuito impreso 6 es un placa de circuito impreso de doble cara dispuesta encajada en un rebajo 9 del contorno interior de la abertura de dicha caja 3, quedando totalmente cubierta por dicha tapa 4, la cual es preferiblemente de un material metálico, tal como de una aleación de aluminio moldeada, susceptible de disipar energía térmica generada por el circuito electrónico. Esta disposición admite que la tapa 4 sea fácilmente sellada herméticamente y/o precintada una vez colocada, con lo que se obtiene una unidad compacta, hermética y a prueba de manipulaciones por parte de personal no autorizado.The arrangement of the printed circuit board 6 according to a first embodiment of the invention is shown in Fig. 2. In the illustrated example, said printed circuit board 6 is a double-sided printed circuit board arranged embedded in a recess 9 of the inner contour of the opening of said box 3, being completely covered by said cover 4, which is preferably of a metallic material, such as an aluminum alloy molded, capable of dissipating thermal energy generated by the electronic circuit. This arrangement admits that the cover 4 is easily sealed tightly and / or sealed once it is placed, thus obtaining a compact, hermetic and tamper-proof unit by unauthorized personnel.
La placa de circuito impreso de doble cara 6 de la Fig. 2 tiene pistas electroconductoras (no mostradas en las figuras) situadas en la cara más exterior de la misma. Estas pistas quedan enfrentadas a la cara más interior de la tapa 4 metálica, y por consiguiente es necesario evitar posible cortocircuitos debidos al contacto de la tapa 4 metálica con las citadas pistas. En el ejemplo mostrado en la Fig. 2, dicha placa de circuito impreso 6 de doble cara queda adosada a dicha tapa 4 en el interior de la caja 3, y se incluye una capa 8 de material eléctricamente aislante interpuesta entre la placa 6 y la tapa 4. Ventajosamente, dicha capa 8 de material eléctricamente aislante es una capa de una resina sintética aplicada, ya sea durante su proceso de fabricación o en un proceso posterior, directamente sobre la cara más exterior de la placa de circuito impreso 6 de doble cara, cubriendo sus pistas y entrepistas. Otra posible solución alternativa, no mostrada, consiste en disponer dicha placa de circuito impreso 6 de doble cara en el interior de la caja 3 de manera que su cara más exterior queda distanciada de la cara más interior de la tapa 4. Para ello, el citado rebajo 9 donde se encaja la placa de circuito impreso 6 es suficientemente profundo para que la misma, medíante la conveniente colocación de unos pequeños separadores entre placa 6 y tapa 4, quede en el interior de la caja 3 a una distancia adecuada de la tapa 4. Para aquellos casos en los que el circuito electrónico es más simple y en los que las condiciones externas no exigen una especial hermetización de la caja, la presente invención propone un ejemplo de realización alternativo, mostrado en las Figs. 1 , 3 y 4, según el cual dicha placa de circuito impreso 6 es un placa de circuito impreso de una sola cara, que comprende un substrato laminar de material dieléctrico el cual forma por sí mismo la citada tapa 4 de la caja 3. Así, la placa de circuito impreso 6 comprende el citado substrato laminar dieléctrico, el cual tiene todas las pistas y todos los componentes del circuito electrónico en su cara más interior, y el cual está recortado adecuadamente siguiendo el contorno de la caja 3 de la transmisión y está provisto de unos orificios 10 para el paso de unos tornillos 11 destinados a ser roscados en unos agujeros 12 de la caja 3 para la fijación de la placa de circuito impreso 6 cubriendo la abertura de dicha caja 3 en funciones de tapa 4. Tal como se muestra en la Fig. 4 (siendo también válido para el ejemplo de realización de la Fig. 2), el sensor de efecto Hall 64 está situado en la placa de circuito impreso 6 de manera que, una vez colocado, queda situado dentro de la caja 3 en un compartimento 31 de la misma dentro del cual gira una porción del árbol de salida del motor 1. A esta porción está fijado un imán que gira junto con dicho árbol. Así, el sensor de efecto Hall 64 queda situado en dicho compartimento 31 muy próximo a dicho imán giratorio para generar los citados pulsos indicativos de la velocidad y sentido de giro del motor 1 que son enviados como señal de entrada al microprocesador 61 , el cual, junto con la mencionada etapa de distribución de potencia 62 quedan situados dentro un compartimento principal 32 de la caja 3 donde gira una rueda dentada (no mostrada) la cual engrana con un tornillo-sin-fin solidario del árbol de salida del motor 1 a través de una abertura 33 de comunicación interna. Esta rueda dentada está conectada mediante un acoplamiento elástico y un arrastrador a un piñón dentado de salida montado de manera susceptible de girar coaxialmente a dicha rueda dentada. (Para una mayor claridad del dibujo se han omitido el árbol del motor y los componentes de la transmisión). Por su parte, los condensadores 63 quedan situados dentro de uno o más compartimentos 34 independientes de la caja 3 configurados en la periferia del compartimento principal 32 aprovechando espacios muertos que quedan entre otras configuraciones necesarias, por ejemplo, para la fijación de la tapa 4 a la caja 3 o la fijación del conjunto formado por la caja 3, con la placa de circuito impreso 6 asociado a la tapa 4, y el motor 1 a la correspondiente estructura de soporte en el vehículo. El conector 7 está situado en la placa de circuito impreso 6 de manera que, una vez montado, queda dispuesto entre dicha placa de circuito impreso 6 y un alojamiento 13 de la caja 3 de manera que unas espigas de contacto 7a (o alternativamente orificios de contacto) del conector 7 son accesibles desde fuera de la caja 3. El cuerpo del conector 7 encaja ajustadamente en dicho alojamiento 13 de la caja 3 de manera que, en el ejemplo de realización de la Fig. 2, resulta fácil de hermetizar la interficie entre los mismos.The double-sided printed circuit board 6 of Fig. 2 has electroconductive tracks (not shown in the figures) located on the outermost side thereof. These tracks face the innermost face of the metal cover 4, and therefore it is necessary to avoid possible short circuits due to the contact of the metal cover 4 with said tracks. In the example shown in Fig. 2, said double-sided printed circuit board 6 is attached to said cover 4 inside the box 3, and a layer 8 of electrically insulating material interposed between the plate 6 and the enclosure is included. cover 4. Advantageously, said layer 8 of electrically insulating material is a layer of a synthetic resin applied, either during its manufacturing process or in a subsequent process, directly on the outermost face of the double-sided printed circuit board 6 , covering its tracks and entrepistas. Another possible alternative solution, not shown, consists in arranging said double-sided printed circuit board 6 inside the box 3 so that its outermost face is distanced from the innermost face of the lid 4. For this, the said recess 9 where the printed circuit board 6 fits is deep enough so that it, through the convenient placement of small spacers between plate 6 and cover 4, is inside the box 3 at a suitable distance from the cover 4. For those cases in which the electronic circuit is simpler and in which the external conditions do not require special sealing of the box, the present invention proposes an alternative embodiment, shown in Figs. 1, 3 and 4, according to which said printed circuit board 6 is a single-sided printed circuit board, comprising a sheet substrate of dielectric material which forms the aforementioned cover 4 of the box 3. , the printed circuit board 6 comprises said dielectric sheet substrate, which has all the tracks and all the components of the electronic circuit on its innermost face, and which is properly trimmed following the contour of the transmission case 3 and is provided with holes 10 for the passage of screws 11 intended to be threaded into holes 12 of the case 3 for fixing the printed circuit board 6 covering the opening of said box 3 in cover functions 4. As shown in Fig. 4 (also being valid for the exemplary embodiment of Fig. 2), the Hall effect sensor 64 is located on the printed circuit board 6 of so that, once placed, it is located inside the box 3 in a compartment 31 thereof in which a portion of the motor output shaft 1 rotates. To this portion is attached a magnet that rotates together with said shaft. Thus, the Hall effect sensor 64 is located in said compartment 31 very close to said rotating magnet to generate said pulses indicative of the speed and direction of rotation of the motor 1 that are sent as an input signal to the microprocessor 61, which, together with said power distribution stage 62, a main compartment 32 of the box 3 is located where a toothed wheel (not shown) rotates which meshes with a screw-endless of the output shaft of the motor 1 through of an internal communication opening 33. This gearwheel is connected by an elastic coupling and a drive to an output gearwheel mounted so that it can rotate coaxially to said gearwheel. (For greater clarity of the drawing, the engine shaft and transmission components have been omitted.) On the other hand, the capacitors 63 are located inside one or more compartments 34 independent of the box 3 configured in the periphery of the main compartment 32 taking advantage of dead spaces that remain among other necessary configurations, for example, for fixing the cover 4 a the box 3 or the fixing of the assembly formed by the box 3, with the printed circuit board 6 associated with the cover 4, and the motor 1 to the corresponding support structure in the vehicle. The connector 7 is located on the printed circuit board 6 so that, once mounted, it is arranged between said printed circuit board 6 and a housing 13 of the box 3 so that contact pins 7a (or alternatively holes of contact) of the connector 7 are accessible from outside the box 3. The body of the connector 7 fits tightly into said housing 13 of the box 3 so that, in the Example of embodiment of Fig. 2, it is easy to seal the interface between them.
