Abstract

In mechanisms for locking vehicle doors or tailgates, the bolt (13) is locked in such a way that multiple movable elements are involved and the failure of any of these elements can result in the door or tailgate not being properly closed. The aim of the invention is to detect this situation by including a greater number of sensors that are responsible not only for checking the position of the bolt (13), but also for checking the relative position of a first latch element (12) and a second latch element (14), using sensors (8-8'-8'') associated with respective PCBA circuits (7-7'-7'') that are connected by means of flexible circuits (10) to a general PCBA (9) that receives signals from the three sensors and emits a single status signal, which warns of improper closure if all the elements checked by the sensors do not match the relative position provided for same, all of the foregoing being integrated in a casing having a shape adapted to the configuration of the latch.

DISPOSITIVO PARA EL CONTROL DE PESTILLOS DE PUERTAS, PORTONES Y DEVICE FOR CONTROLLING LATCHES ON DOORS, GATES AND
SIMILARES EN VEHÍCULOS SIMILAR IN VEHICLES
DESCRIPCIÓN DESCRIPTION
SECTOR DE LA TÉCNICA TECHNIQUE SECTOR
La presente invención se refiere a un dispositivo para el control de pestillos de puertas, portones traseros, capó y similares en vehículos, cuya finalidad es la de detectar la posición de dicho pestillo. The present invention refers to a device for controlling door latches, tailgates, hoods and the like in vehicles, the purpose of which is to detect the position of said latch.
El objeto de la invención es proporcionar unos medios de sensorización que eviten la apertura accidental de la puerta o portón asociado a dicho mecanismo de cierre. The object of the invention is to provide sensor means that prevent the accidental opening of the door or gate associated with said closing mechanism.
El sensor detecta varios puntos a la vez de la posición del pestillo de forma que la salida del sensor respecto a la posición del pestillo, proporciona una única señal correcta cuando el pestillo está bien cerrado, evitando así problemas derivados de puertas mal cerradas y de la apertura involuntaria del pestillo. The sensor detects several points at the same time of the latch position so that the output of the sensor with respect to the latch position, provides a single correct signal when the latch is properly closed, thus avoiding problems derived from improperly closed doors and the inadvertent opening of the latch.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el ámbito de aplicación práctica de la invención, el de los cierres de portones, puertas, capós y similares en vehículos, es habitual incluir un sensor que detecta la posición del pestillo, en orden a asegurar que todas las puertas están cerradas antes de comenzar y durante la marcha. In the field of practical application of the invention, that of closing doors, doors, hoods and the like in vehicles, it is usual to include a sensor that detects the position of the latch, in order to ensure that all doors are closed before starting. and during the march.
Sin embargo, este tipo de mecanismos presentan una problemática cuando la puerta o portón no se cierra completamente, pudiendo provocar la apertura involuntaria del sistema de pestillo. However, this type of mechanism presents a problem when the door or gate does not close completely, which may cause the involuntary opening of the latch system.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
El dispositivo para el control de pestillos de puertas, portones y similares en vehículos que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta. The device for controlling door latches, gates and the like in vehicles that It is recommended that it satisfactorily resolves the aforementioned problem.
Para ello se ha previsto que el dispositivo de la invención se materialice en una carcasa de sensorización, mediante la que se monitorizan de forma simultánea tres elementos diferentes del sistema del pestillo mediante un interruptor Hall en cada uno de ellos. For this, it has been foreseen that the device of the invention is embodied in a sensor housing, by means of which three different elements of the bolt system are monitored simultaneously by means of a Hall switch in each one of them.
Estos puntos de control son: These checkpoints are:
• Pasador de la puerta. • Door latch.
• Un primer elemento de pestillo. • A first latch element.
• Un segundo elemento de pestillo. • A second latch element.
A través de un circuito flexible se consigue tener los 3 interruptores Hall colocados en diferentes lugares dentro de la carcasa del sensor mientras se conectan eléctricamente entre ellos. Sus señales de salida se procesan juntas para proporcionar una única salida. Through a flexible circuit it is possible to have the 3 Hall switches placed in different places inside the sensor housing while they are electrically connected to each other. Their output signals are processed together to provide a single output.
De forma más concreta, el dispositivo de la invención consta de dos carcasas acoplables entre sí, una carcasa principal, sobre la que se implanta la electrónica de control, y una carcasa protectora destinada a aislar de polvo o suciedad dicha electrónica, si bien el dispositivo podría disponer de una sola carcasa convenientemente aislada, por ejemplo mediante sellado tipo epoxi. More specifically, the device of the invention consists of two casings that can be coupled together, a main casing, on which the control electronics are implanted, and a protective casing intended to isolate said electronics from dust or dirt, although the device it could have a single casing suitably insulated, for example by means of epoxy-type sealing.
Así pues en la carcasa principal se establece en su cara posterior un conector, cables u otras conexiones eléctricas, a través de los cuales la electrónica de sensorización se comunica con la centralita del vehículo, contando en su cara anterior con tres sensores/detectores, preferentemente de tipo Hall, asociados a respectivos circuitos PCBA, pudiendo utilizarse igualmente chips con cables en lugar de los referidos sensores/detectores de tipo montaje sobre PCB. Thus, in the main casing, a connector, cables or other electrical connections are established on its rear face, through which the sensor electronics communicate with the vehicle's control unit, with three sensors/detectors on its front face, preferably of the Hall type, associated with the respective PCBA circuits, and chips with cables can also be used instead of the aforementioned sensors/detectors of the PCB mounting type.
Tanto los tres circuitos PCBA asociados a los sensores/detectores como el circuito PCBA general destinado a procesar las señales, están conectados entre sí preferentemente mediante un circuito flexible o rigid-flex, o bien mediante otros medios como cables. Both the three PCBA circuits associated with the sensors/detectors and the general PCBA circuit for processing the signals are preferably connected to each other. through a flexible or rigid-flex circuit, or through other means such as cables.
En tal sentido, si bien podrían utilizarse otro tipo de conexiones, la utilización de circuitos de tipo rigid-flex facilita la adaptación al espacio reducido y la configuración de cada pestillo. In this sense, although other types of connections could be used, the use of rigid-flex type circuits facilitates adaptation to reduced space and the configuration of each latch.
Por su parte la carcasa de protección se acopla a la carcasa principal y se fija mecánicamente a ésta por cualquier medio convencional. For its part, the protective casing is coupled to the main casing and is mechanically fixed to it by any conventional means.
Cada uno de los tres circuitos o PCBA están enfrentados a una zona de metal del pestillo para la cual se quiere conocer su posición concreta. Each of the three circuits or PCBAs face a metal area of the latch for which you want to know its specific position.
Para cada uno de los sensores/chips, la presencia del metal delante del sensor dará preferentemente, una salida “high” y la no presencia dará una salida “low”. For each of the sensors/chips, the presence of metal in front of the sensor will preferably give a "high" output and its absence will give a "low" output.
Las salidas “high” y “low” quedarán definidas por unos niveles de voltaje con unas tolerancias preestablecidas. The “high” and “low” outputs will be defined by voltage levels with preset tolerances.
Debido a que no en los tres casos, la salida “high” corresponde con el estado deseado para la posición del pestillo como salida correcta, la integración de las señales de los tres sensores se realiza mediante puertas lógicas tipo “AND-OR-NOT” y sus combinaciones, de forma que los posibles estados de las partes del pestillo, corresponden con los estados de los tres sensores “high” y “low”, y que solo hay una combinación o estado válido que se corresponde con el pestillo correctamente colocado en los tres puntos en los que detecta la posición, utilizándose dichas puertas lógicas de un modo preferente pero sin excluir otros medios de combinación de salidas de los sensores. Since the "high" output does not correspond to the desired state for the latch position as the correct output in all three cases, the integration of the signals from the three sensors is done through logic gates of the "AND-OR-NOT" type. and their combinations, so that the possible states of the latch parts correspond to the states of the three sensors "high" and "low", and that there is only one valid combination or state that corresponds to the latch correctly placed in the three points at which it detects the position, said logic gates being used in a preferred way but without excluding other means of combining the outputs of the sensors.
A partir de esta estructuración, se derivan las siguientes ventajas: From this structure, the following advantages are derived:
• El hecho de que la invención integre tres sensores en uno, proporciona la ventaja de instalar un único sensor en la aplicación en lugar de dos o más sensores. • The fact that the invention integrates three sensors in one, provides the advantage of installing a single sensor in the application instead of two or more sensors.
• El hecho de que sea un único sensor disminuye el coste, el tiempo de instalación, el mantenimiento, así como el peso en el vehículo lo cual redunda en un menor consumo de combustible y de batería, así como un menor consumo de recursos para el medioambiente. • The fact that it is a single sensor reduces the cost, installation time, maintenance, as well as the weight in the vehicle, which results in less fuel and battery consumption, as well as less consumption of resources for the environment.
• El hecho de integrar las tres señales en una, proporciona una señal inequívoca de que todos los puntos definidos para el pestillo, se encuentran en la posición definida para el cierre, evitando así el circular con las puertas abiertas o la apertura involuntaria de estas con los efectos de seguridad que de ello se derivan. • The fact of integrating the three signals into one provides an unequivocal signal that all the points defined for the bolt are in the defined position for closing, thus avoiding driving with the doors open or their involuntary opening with the safety effects that derive from it.

Based on this structure, for each of the sensors/chips, the presence of metal in front of the sensor will give a "high" output and its absence will give a "low" output.
Tal y como se ha dicho con anterioridad, dado que no en los tres casos, la salida “high” corresponde con el estado deseado para la posición del pestillo como salida correcta, la integración de las señales de los tres sensores se realiza mediante puertas lógicas del tipo “AND-OR-NOT y combinaciones, de forma que los posibles estados de las partes del pestillo, corresponden con los estados de los tres sensores “high” y “low”, y que solo hay una combinación o estado válido que se corresponde con el pestillo correctamente colocado en los tres puntos en los que detecta la posición. As previously stated, since the “high” output does not correspond to the desired state for the latch position as the correct output in all three cases, the integration of the signals from the three sensors is done through logic gates. of the "AND-OR-NOT" type and combinations, so that the possible states of the latch parts correspond to the states of the three sensors "high" and "low", and that there is only one valid combination or state that can be corresponds with the latch correctly positioned in the three points in which it detects the position.
