Description

La présente invention concerne un système de commande de l'état de condamnation/décondamnation d'une serrure de porte notamment de véhicule automobile.The present invention relates to a system for controlling the state of locking / unlocking of a door lock, especially of a vehicle automobile.

On connaít déjà dans l'état de la technique, des systèmes de commande de ce type qui comportent un contact de détection de l'état d'ouverture/fermeture de la porte et deux contacts de condamnation/décondamnation de la serrure, qui sont associés à un levier de verrou de celle-ci.We already know in the prior art, control systems of this type which include an opening / closing state detection contact of the door and two locking / unlocking contacts of the lock, which are associated with a lock lever thereof.

De plus, ces serrures comportent par exemple au moins un contact de supercondamnation et des conducteurs d'alimentation d'un organe de motorisation de celles-ci.In addition, these locks comprise for example at least one contact of deadlock and supply conductors of a motorized member of these.

On conçoit alors que le nombre de conducteurs utilisés est relativement important, ce qui nécessite l'utilisation de connecteurs comportant un nombre de voies correspondant, et se traduit par des coûts de fabrication d'un tel système relativement élevés et une fiabilité réduite.It can therefore be seen that the number of conductors used is relatively important, which requires the use of connectors with a number of corresponding tracks, and results in manufacturing costs of such relatively high system and reduced reliability.

Le but de l'invention est donc de résoudre ces problèmes en réduisant le nombre de voies utilisées.The object of the invention is therefore to solve these problems by reducing the number of channels used.

A cet effet, l'invention a pour objet un système de commande de l'état de condamnation/décondamnation d'une serrure de porte, notamment de véhicule automobile, caractérisé en ce qu'il comporte au moins un contact à ouverture de détection de l'état d'ouverture/fermeture de la porte et un premier et un second contacts à fermeture de condamnation/décondamnation de la serrure, associés à un levier de verrou de la serrure, en ce que le levier de verrou de la serrure comporte trois portions de came dont l'une est associée au premier contact et les deux autres sont associées au second contact et sont disposées de part et d'autre de celui-ci, pour permettre l'actionnement de ce second contact seul lorsque le levier de verrou est déplacé dans un premier sens et des deux contacts lorsque le levier de verrou est déplacé dans l'autre sens et en ce que le premier contact est connecté en parallèle sur le contact à ouverture de détection de l'état d'ouverture/fermeture de la porte.To this end, the invention relates to a state control system for locking / unlocking a door lock, especially for a vehicle automobile, characterized in that it comprises at least one opening contact of detection of the state of opening / closing of the door and a first and a second contacts to close the lock / unlock the lock, associated with a lock latch lever, in that the latch lever on the lock has three cam portions, one of which is associated with the first contact and the other two are associated with the second contact and are arranged to on either side of it, to allow actuation of this second contact only when the lock lever is moved in one direction and both contacts when the latch lever is moved in the opposite direction and in that the first contact is connected in parallel on the contact with detection opening the door opening / closing state.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • la Fig. représente un schéma synoptique illustrant la structure d'une portion d'un système de commande selon l'invention; et
  • la Fig.2 représente un tableau illustrant le fonctionnement de cette structure.
The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which:
  • Fig. represents a block diagram illustrating the structure of a portion of a control system according to the invention; and
  • Fig.2 shows a table illustrating the operation of this structure.

On reconnaít en effet sur la figure 1, un système de commande de l'état de condamnation/décondamnation d'une serrure de porte, notamment de véhicule automobile.We recognize in fact in Figure 1, a control system the state of conviction / unlocking of a door lock, in particular of motor vehicle.

De façon classique, un tel système comporte un contact à ouverture, désigné par la référence générale 1, permettant de détecter l'état d'ouverture/fermeture de la porte correspondante et deux contacts à fermeture de condamnation/décondamnation de la serrure désignés par les références générales 2 et 3 sur cette figure.Conventionally, such a system includes an opening contact, designated by the general reference 1, making it possible to detect the opening / closing state of the corresponding door and two locking / unlocking closing contacts of the lock designated by the general references 2 and 3 in this figure.

Ces deux contacts 2 et 3 sont associés à un levier de verrou désigné par la référence générale 4 sur cette figure, de la serrure, ce levier comportant trois portions de came, désignées par les références générales 5,6 et 7 respectivement sur cette figure, dont l'une 5 est associée à l'un des contacts, c'est-à-dire au premier contact 2 et dont les deux autres portions de came, c'est-à-dire les portions 6 et 7, sont associées à l'autre contact, c'est-à-dire au second contact 3.These two contacts 2 and 3 are associated with a designated latch lever by the general reference 4 in this figure, of the lock, this lever comprising three cam portions, designated by the general references 5,6 and 7 respectively in this figure, one of which 5 is associated with one of the contacts, that is to say at the first contact 2 and of which the two other cam portions, that is to say the portions 6 and 7 are associated with the other contact, that is to say with the second contact 3.

Ces deux autres portions de came 6 et 7 sont en fait disposées de part et d'autre de ce second contact 3.These two other cam portions 6 and 7 are in fact arranged on either side of this second contact 3.

On conçoit alors que selon le sens de déplacement de ce levier de verrou 4, une telle structure permet d'actionner le contact 3 seul lorsque le levier de verrou 4 pivote par exemple dans un sens horaire de condamnation C, tandis que si le levier de verrou pivote dans le sens anti-horaire de décondamnation D, les deux contacts 2 et 3 sont actionnés par les portions de came correspondantes 5 et 6 de ce levier.It can therefore be seen that, depending on the direction of movement of this lever lock 4, such a structure makes it possible to actuate contact 3 alone when the lever latch 4 pivots for example in a clockwise locking direction C, while that if the latch lever pivots anticlockwise to unlock D, the two contacts 2 and 3 are actuated by the corresponding cam portions 5 and 6 of this lever.

De plus, dans le système selon l'invention, le premier contact, c'est-à-dire le contact 2 est connecté en parallèle sur le contact à fermeture de détection de l'état d'ouverture/fermeture de la porte, désigné par la référence générale 1.In addition, in the system according to the invention, the first contact, that is to say contact 2 is connected in parallel on the detection closing contact the state of opening / closing of the door, designated by the general reference 1.

La logique de fonctionnement d'une telle structure est illustrée sur le tableau de la figure 2, dans laquelle un 0 représente un circuit ouvert et un 1 représente un circuit fermé, la voie 1 correspondant à la sortie des contacts 1 et 2 en parallèle et la voie 2 correspondant à la sortie du contact 3.The operating logic of such a structure is illustrated on the table of figure 2, in which a 0 represents an open circuit and a 1 represents a closed circuit, channel 1 corresponding to the output of contacts 1 and 2 in parallel and channel 2 corresponding to the output of contact 3.

On conçoit alors qu'une telle structure permet de réduire le nombre de voies utilisées et donc le nombre de conducteurs et de connecteurs correspondants, ce qui permet d'une part, de réduire le coût de fabrication d'un tel système et d'autre part, d'en augmenter la fiabilité.It can therefore be seen that such a structure makes it possible to reduce the number of channels used and therefore the number of corresponding conductors and connectors, which allows on the one hand, to reduce the manufacturing cost of such a system and secondly, to increase its reliability.

Il va de soi bien entendu que d'autres modes de réalisation de ce système peuvent être envisagés.It goes without saying of course that other embodiments of this system can be considered.
