Description

MECANISMO ELEVALUNAS CON ELEMENTO TRACTOR FILIFORME WINDOW MECHANISM WITH FILIFORM TRACTOR ELEMENT
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un mecanismo elevalunas con elemento tractor filiforme, que aporta, a la función a que se destina, ventajas y características, que se describen en detalle más adelante, que suponen una mejora del estado actual de la técnica. The invention, as expressed in the statement of the present descriptive memory, refers to a window regulator mechanism with a filiform traction element, which provides, to the function for which it is intended, advantages and characteristics, which are described in detail later, which suppose an improvement on the current state of the art.
El objeto de la presente invención recae en un mecanismo elevalunas de vehículo, o sistema de apertura de lunas o cristales similar, por ejemplo para el techo solar, que se distingue esencialmente por el hecho de que, en sustitución de las sirgas o cables de acero enrollables normalmente utilizados en estos sistemas, comprende un elemento tractor conformado a partir de un cuerpo filiforme dotado de protuberancias o eslabones que facilitan su agarre, engranaje o pinzamiento para la transmisión del movimiento de la luna por tracción al encajar en cavidades complementarias de un tambor giratorio y arrastre de los extremos a través de carros que deslizan en unas guías. The object of the present invention falls on a vehicle window lifter mechanism, or similar window or glass opening system, for example for the sunroof, which is essentially distinguished by the fact that, instead of steel wire ropes or cables rollers normally used in these systems, comprises a traction element formed from a threadlike body equipped with protuberances or links that facilitate its grip, engagement or clamping for the transmission of the movement of the window by traction when fitting into complementary cavities of a rotating drum and drag the ends through carriages that slide on some guides.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de componentes para automoción, centrándose particularmente en el ámbito de los mecanismos elevalunas o techo solar. ANTECEDENTES DE LA INVENCIÓN The field of application of the present invention falls within the industry sector dedicated to the manufacture of automotive components, focusing particularly on the field of window regulators or sunroof mechanisms. BACKGROUND OF THE INVENTION
En la actualidad, los sistemas de elevalunas o techo solar para vehículos pueden dividirse en tres grandes grupos: Currently, window lifter or sunroof systems for vehicles can be divided into three large groups:
- Elevalunas de cable, que pueden ser monocarril o de más de un carril.- Cable window regulators, which can be monorail or more than one rail.
- Techos solares de sirga. - Solar towroof roofs.
- Elevalunas de brazo o tijera, que pueden ser de simple o doble brazo, (en desuso, debido a su alto coste, peso y volumen) - Arm or scissor window lifter, which can be single or double arm, (in disuse, due to its high cost, weight and volume)
Los sistemas elevalunas de cable utilizados habitualmente, están constituidos por al menos un carril metálico sobre el cual desliza un carro que se encuentra unido (o simplemente empuja) a la luna del vehículo. El deslizamiento del carro, en uno u otro sentido, provoca el cierre o apertura de la luna. The commonly used cable window systems are made up of at least one metal rail on which a carriage slides that is attached to (or simply pushes) the vehicle window. The sliding of the car, in one direction or another, causes the closing or opening of the window.
El uso del cable implica la adición al sistema de una serie de elementos dedicados a disminuir el rozamiento (poleas y sus respectivos remaches y soportes), a mantener la tensión debido a la relajación del cable en su ciclo de vida (retrapaje en elevalunas sin marco), y al uso de fundas conductoras y pipetas para evitar el desmontaje del cable durante transporte y ensamblaje final en puerta o techo. The use of the cable implies the addition to the system of a series of elements dedicated to reducing friction (pulleys and their respective rivets and supports), to maintaining the tension due to the relaxation of the cable in its life cycle (retrapping in frameless window regulators ), and the use of conductive sheaths and pipettes to avoid disassembling the cable during transportation and final assembly on the door or ceiling.
Paralelamente, un motor transmite el movimiento a los carros mediante dos cables (monocarril) o tres cables (doble carril), que se enrollan o desenrollan en un tambor unido al eje del motor. In parallel, a motor transmits the movement to the carriages by means of two cables (monorail) or three cables (double rail), which are wound or unwound on a drum attached to the motor shaft.
El uso del cable enrollado en un tambor tiene asociados los siguientes fenómenos entre otros: Problemas por la naturaleza del cable: o Puede saltar de espira en el tambor donde se enrolla, o bien estar mal montado, lo cual, a su vez, provoca: The use of cable wound on a drum is associated with the following phenomena among others: Problems due to the nature of the cable: o It can jump out of the loop on the drum where it is wound, or it can be poorly assembled, which, in turn, causes:
■ Paro de los carros debido a bloqueo del cable o rotura de cable/tambor/tapa. ■ Car stoppage due to cable blockage or broken cable/drum/cover.
■ Ruidos por fricción del cable consigo mismo, o Excesiva elongación del cable durante su vida útil, provocando: ■ Noises due to friction of the cable with itself, or Excessive elongation of the cable during its useful life, causing:
■ Tiempos de cierre o apertura no aceptables, falta de tensión en el sistema (posición de la luna no firme, susceptible a manipularse dejando acceso al interior del vehículo, problemas sujeción en carretera (fuerza aerodinámica)). ■ Unacceptable closing or opening times, lack of tension in the system (window position not firm, susceptible to manipulation allowing access to the interior of the vehicle, problems holding the road (aerodynamic force)).
Problemas por la aplicación de los cables en el elevalunas: o Excesiva fricción debido al rozamiento entre el cable y el resto de elementos (sobre todo con las fundas conductoras del cable). Mayor consumo del motor o par de accionamiento manual. Ruido y/o pérdida de funcionalidad por deterioro de las piezas. o Excesiva complejidad del mecanismo en cuanto a número de elementos y ensamblaje. o Dificultad de reutilizar la tapa tambor debido a la configuración de las fundas conductoras del cable, siendo una excesiva longitud o curvatura fuente de problemas de rozamiento, consumo de motor, velocidad de la luna e incluso rotura del cable. Para intentar solucionar estos problemas, se llevan a cabo numerosos estudios de ruteado de cable, llegando normalmente a un compromiso de funcionamiento que suele conllevar motores de alto par, caros y riesgo de no superar la durabilidad o especificaciones de velocidad de cierre o apertura de la luna, debido a la enorme fricción interna del sistema. Problems due to the application of the cables in the window regulator: o Excessive friction due to friction between the cable and the rest of the elements (especially with the conductive sheaths of the cable). Higher motor consumption or manual drive torque. Noise and/or loss of functionality due to deterioration of the parts. o Excessive complexity of the mechanism in terms of number of elements and assembly. o Difficult to reuse the drum cover due to the configuration of the conductive sheaths of the cable, being an excessive length or curvature a source of friction problems, motor consumption, moon speed and even cable breakage. In order to try to solve these problems, numerous cable routing studies are carried out, normally reaching a performance compromise that usually entails high-torque, expensive motors and the risk of not exceeding the durability or closing or opening speed specifications of the cable. moon, due to the enormous internal friction of the system.
El principal objetivo de la presente invención es pues, el desarrollo de un nuevo tipo de sistema, alternativo al cable o a la sirga, que permita prescindir de la necesidad de enrollar cable y en su lugar lo arrastre, reduciendo así el rozamiento interno en estos sistemas y a la vez simplificando el número de piezas necesarias en el mecanismo. The main objective of the present invention is, therefore, the development of a new type of system, alternative to the cable or towline, which makes it possible to dispense with the need to wind the cable and instead drag it, thus reducing internal friction in these systems. and at the same time simplifying the number of parts needed in the mechanism.

EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
El mecanismo elevalunas con elemento tractor filiforme que la invención propone se configura como una solución idónea al objetivo anteriormente señalado, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. The window regulator mechanism with a filiform traction element that the invention proposes is configured as an ideal solution to the aforementioned objective, the characterizing details that make it possible and that distinguish it conveniently included in the final claims that accompany this description.
Concretamente, lo que la invención propone, como se ha apuntado anteriormente, es un mecanismo elevalunas de vehículo, o sistema similar, por ejemplo de techo solar, que se distingue esencialmente por el hecho de que, en lugar de sirgas o cables de acero enrollables, comprende un elemento tractor conformado a partir de un cuerpo filiforme dotado de protuberancias o eslabones que facilitan su agarre, engranaje o pinzamiento para la transmisión del movimiento al encajar en cavidades complementarias de un tambor giratorio, de tal modo que dicho elemento tractor filiforme, con función asimilable a un cable, correa o cadena de transmisión, permite convertir el giro del tambor a través de un accionamiento que puede ser manual (mediante manivela) o eléctrico (motor), en un movimiento de desplazamiento lineal de la luna o cristal (en adelante luna). Specifically, what the invention proposes, as noted above, is a vehicle window mechanism, or similar system, for example a sunroof, which is essentially distinguished by the fact that, instead of rolling steel wire ropes or cables , comprises a Tractor element formed from a filiform body equipped with protuberances or links that facilitate its grip, engagement or clamping for the transmission of movement by fitting into complementary cavities of a rotating drum, in such a way that said filiform tractor element, with a function similar to a transmission cable, belt or chain, allows converting the rotation of the drum through a drive that can be manual (by means of a crank) or electric (motor), in a movement of linear displacement of the window or glass (hereinafter moon). .
Es importante destacar que el elemento tractor filiforme con protuberancias que comprende el mecanismo de la invención puede presentar distinta configuración y disposición en tales protuberancias y, por ejemplo, estas pueden ser esféricas, cilindricas, poliédricas, etc., o incluso definir los eslabones de una cadena, y estar más o menos separadas entre sí. Si bien, en todo caso, las protuberancias son siempre idénticas entre sí y están separadas unas de otras a la misma distancia, repartiéndose a lo largo de toda la extensión del cuerpo filiforme en que se integran. It is important to note that the threadlike traction element with protuberances that comprises the mechanism of the invention can have a different configuration and arrangement in such protuberances and, for example, these can be spherical, cylindrical, polyhedral, etc., or even define the links of a chain, and be more or less separated from each other. Although, in any case, the protuberances are always identical to each other and are separated from each other at the same distance, spreading out along the entire length of the threadlike body in which they are integrated.
Además, en los extremos del elemento tractor filiforme se prevé la existencia de unos miembros regruesados de sujeción, para facilitar la fijación de los mismos en el carro de arrastre, los cuales, a su vez, también son de configuración variable. In addition, at the ends of the filiform traction element, there are thickened fastening members, to facilitate fixing them on the drag carriage, which, in turn, are also of variable configuration.

Preferentemente, la guía o guías están conformadas por un cuerpo tubular hueco por cuyo interior discurre el elemento o elementos tractores sujetos por sus extremos al carro de arrastre situado externamente y de modo que, a su vez, se desliza de un extremo a otro de la guía. Para la sujeción de dichos extremos del elemento tractor filiforme, éste cuenta en ambos extremos con un miembro de sujeción regruesado para encajar en un alojamiento del carro previsto al efecto. Preferably, the guide or guides are made up of a hollow tubular body through which the traction element or elements run, attached at their ends to the drive carriage located externally and so that, in turn, it slides from one end of the rail to the other. guide. For the fastening of said ends of the filiform traction element, the latter has a thickened fastening member at both ends to fit into a housing on the carriage provided for this purpose.
Además, de modo preferido, la guía o guías cuentan con una ranura longitudinal que se extiende, total o parcialmente, a lo largo de la misma para facilitar el paso de dichos miembros de sujeción fuera de la guía y sujetarse al carro de arrastre. In addition, preferably, the guide or guides have a longitudinal slot that extends, totally or partially, along it to facilitate the passage of said holding members out of the guide and hold on to the tow truck.
Preferentemente, la guía o guías cuentan en los respectivos extremos superior e inferior de las mismas, con un cabezal superior e inferior para conducir y orientar correctamente y sin fricción la salida y entrada del elemento tractor filiforme o, en su caso, el cable. Para ello, preferentemente dicho cabezal está conformado por una pieza circular con un orificio de acople a la guía y un canal de guiado circundando su parte central. Alternativamente, dicho cabezal comprende una polea cuando se utiliza un cable. Preferably, the guide or guides have an upper and lower head at their respective upper and lower ends to guide and orientate the exit and entry of the filiform traction element correctly and without friction, or, where appropriate, the cable. For this, said head is preferably made up of a circular piece with a hole for coupling to the guide and a guide channel surrounding its central part. Alternatively, said head comprises a pulley when a cable is used.
Además, de preferencia, la parte central de dicho cabezal presenta una perforación destinada a la fijación del vehículo o a destinada incorporar un tornillo o elemento de anclaje similar para permitir la regulación de la luna en caso necesario, normalmente para mecanismos elevalunas de puertas sin marco. In addition, preferably, the central part of said head has a perforation intended for fixing the vehicle or for incorporating a screw or similar anchoring element to allow adjustment of the glass if necessary, normally for window-winder mechanisms on frameless doors.
Por su parte, el tambor en que engrana el elemento de tracción, preferentemente, está conformado por un cuerpo circular provisto de un canal perimetral que presenta una pluralidad de concavidades de configuración acorde a la forma y disposición de las protuberancias del elemento tractor filiforme, de tal modo que estas encajan en dicho canal ajustadamente y, al girar, movido por el accionador, ya sea manivela o motor, provocar el movimiento del elemento tractor filiforme en un sentido u otro. For its part, the drum in which the traction element meshes, preferably, is made up of a circular body provided with a perimeter channel that presents a plurality of configuration concavities according to the shape and arrangement of the protuberances of the threadlike traction element, in in such a way that they fit tightly into said channel and, when they rotate, moved by the actuator, whether it is a crank or a motor, cause the movement of the filiform traction element in one direction or another.
Opcionalmente, cualquier componente del mecanismo elevalunas en contacto con el elemento tractor filiforme con protuberancias comprende un recubrimiento para reducir los ruidos generados por el mecanismo elevalunas así como para mejorar su deslizamiento. Finalmente, cabe señalar que, preferentemente, el tambor o tambores van alojados dentro de una carcasa de protección en la cual, cuando el mecanismo es eléctrico, también se une el motor de accionamiento. Preferentemente, dicha carcasa está dotada de perforaciones pasantes aptas para la inserción de unos tornillos de fijación al vehículo. Optionally, any component of the window lifter mechanism in contact with the protuberant threadlike traction element comprises a coating to reduce the noise generated by the window lifter mechanism as well as to improve its sliding. Finally, it should be noted that, preferably, the drum or drums are housed inside a protective casing in which, when the mechanism is electric, the drive motor is also attached.

Así pues, la principal diferencia del mecanismo de la invención respecto de otros mecanismos similares ya conocidos, y que también comprenden, al menos, dos elementos tractores filiformes, al menos, un carro de arrastre al que se fija los elementos tractores filiformes por sus respectivos extremos, al menos, un elemento de guiado en que se desplaza el carro de arrastre, y al menos, un componente que gira solidariamente al eje de un motor o manivela de accionamiento, es el hecho de que el elemento filiforme, en lugar de un sirga o cable enrollable, es un elemento tractor filiforme con protuberancias gracias a las cuales puede ser fraccionado en un sentido u otro mediante el componente de giro en que se engranan dichas protuberancias. Thus, the main difference of the mechanism of the invention with respect to other similar mechanisms already known, and which also comprise at least two filiform traction elements, at least one drag carriage to which the filiform traction elements are fixed by their respective ends, at least one guide element in which the drag carriage moves, and at least one component that rotates jointly with the axis of a motor or drive crank, is the fact that the filiform element, instead of a wire rope or winding cable, is a filiform traction element with protuberances thanks to which it can be divided in one direction or another by means of the turning component in which said protuberances engage.
Además, el componente que gira solidario al eje, en lugar de ser una bobina donde se enrolla y/o desenrolla el cable para procurar el movimiento del carro, es un cuerpo circular de tracción donde, a modo de rueda motriz engranan las protuberancias del elemento tractor filiforme. In addition, the component that rotates in solidarity with the axis, instead of being a coil where the cable is wound and/or unwound to ensure the movement of the carriage, is a circular traction body where, like a drive wheel, the protuberances of the element engage. threadlike tractor.
Por otra parte, el elemento de guiado, en lugar de ser un carril sobre el que discurre el carro, preferentemente es un cuerpo tubular en cuyo interior se incorpora el elemento tractor filiforme quedando protegido, mientras el carro discurre externamente El mecanismo de la invención proporciona, pues, un nuevo elemento tractor filiforme que disminuye los problemas y número de piezas asociadas al uso de cable o sirga. On the other hand, the guide element, instead of being a rail on which the trolley runs, is preferably a tubular body inside which the filiform traction element is incorporated, remaining protected, while the trolley runs externally. The mechanism of the invention therefore provides a new filiform traction element that reduces the problems and number of parts associated with the use of a cable or towline.
Para ello se dota al elemento tractor filiforme de protuberancias o eslabones que facilitan la transmisión del movimiento de rotación del motor, evitando tener que enrollarlo: For this, the filiform traction element is provided with protuberances or links that facilitate the transmission of the rotational movement of the motor, avoiding having to wind it:
Se acorta la longitud y número de elementos tractores o No enrollado, simplificando el sistema y evitando problemas de salto de espira o mal enrollado. o Un cable o elemento tractor filiforme menos respecto a los elevalunas con cable. o Menor elongación de los elementos tractores por su diseño y longitud, evitando el uso de subsistemas como mecanismos retrapaje (atrapa-cable) para mantener la tensión del sistema durante el ciclo de vida. The length and number of traction or non-coiling elements are shortened, simplifying the system and avoiding problems with jump coils or poor coiling. o One less threadlike cable or traction element compared to window regulators with cable. o Less elongation of the traction elements due to their design and length, avoiding the use of subsystems such as retrapping mechanisms (cable-catch) to maintain system tension during the life cycle.
Se reduce el número de piezas necesarias en el mecanismo en un 60-70% aprox. o Alto grado de compatibilidad con posteriores proyectos con lo que se ahorra en utillaje, peso del mecanismo (50% aprox. ahorro) y espacio empleado en la arquitectura de la puerta. o Menor fricción interna del sistema, ya que los elementos que rozan (especialmente cable o sirga contra las fundas conductoras de alma metálica en forma de espiral) pasan a ser protuberancias o eslabones, sin fundas, que ofrecen menor superficie de contacto y rozamiento. o Menor número de componentes, con menor complejidad de fabricación y fácilmente ensamblables a mano (plug and play) sin necesidad de remaches o soldadura, pudiéndose montar por el cliente opcionalmente (mejores opciones de log ística/ packaging) . o Válido para puertas con o sin marco. The number of parts needed in the mechanism is reduced by approx. 60-70%. o High degree of compatibility with subsequent projects, which saves on tooling, weight of the mechanism (approx. 50% saving) and space used in the architecture of the door. o Less internal friction of the system, since the elements that rub (especially cable or wire against the spiral-shaped metallic core conductive sheaths) become protuberances or links, without sheaths, which offer less contact and friction surface. o Less number of components, with less manufacturing complexity and easily assembled by hand (plug and play) without the need for rivets or welding, being able to assemble By the customer optionally (better logistics/packaging options). o Valid for doors with or without frame.
Este nuevo planteamiento elimina un gran número de problemas asociados al uso del cable de acero o sirga, obteniendo por medio del descrito elemento tractor filiforme que comprende el mecanismo objeto de la invención, unas condiciones de deslizamiento muy deseables y un menor grado de complejidad en el mecanismo. This new approach eliminates a large number of problems associated with the use of the steel cable or wire rope, obtaining by means of the described filiform traction element that includes the mechanism object of the invention, very desirable sliding conditions and a lower degree of complexity in the operation. mechanism.
