Description

SERRURE D'OUVRANT DE VEHICULE AUTOMOBILE  OPENING LOCK FOR MOTOR VEHICLE
L'invention concerne une serrure d'ouvrant de véhicule automobile. The invention relates to an opening lock of a motor vehicle.
Dans un véhicule automobile, afin d'éviter qu'un conducteur laisse sa clé dans le véhicule, lorsqu'il sort et ferme par claquage l'ouvrant immédiatement, l'ouvrant du conducteur et/ou du passager est équipé d'une fonction d'empêchement d'enfermement de la clé, en général sur les ouvrants latéraux avant.  In a motor vehicle, in order to prevent a driver from leaving his key in the vehicle, when he leaves and closes the door immediately, the opening of the driver and / or the passenger is equipped with a function of prevention of locking the key, usually on the front side opening.
Classiquement, cette fonction est réalisée différemment en Classically, this function is performed differently in
Europe et en Asie. Europe and Asia.
En général, en Europe, les serrures sont dépourvues de fonction de condamnation et de décondamnation mécanique, et se verrouillent donc exclusivement électriquement. Une telle serrure est couramment dite de type « Self-Lock ».  In general, in Europe, the locks have no function of locking and mechanical unlocking, and therefore lock exclusively electrically. Such a lock is commonly called "Self-Lock" type.
Une telle serrure comporte en général une fonction couramment appelé « Override » qui consiste à déverrouiller l'ouvrant, lorsqu'une poignée d'ouverture intérieure est actionnée. Une telle serrure, quand elle est fermée par claquage de l'extérieur, ne peut pas être verrouillée manuellement et reste donc déverrouillée, et la clé ne peut être piégée, si elle est restée à l'intérieur.  Such a lock generally comprises a function commonly called "override" which consists in unlocking the opening when an inner opening handle is actuated. Such a lock, when closed externally, can not be locked manually and thus remains unlocked, and the key can not be trapped if it has been left inside.
Certaines de ces serrures sont parfois néanmoins également équipées d'une fonction de secours de verrouillage, qui est actionnée par une interface mécanique de la clé, pouvant être utilisée uniquement quand l'ouvrant est ouvert, dans le but de sécuriser le véhicule lors d'une défaillance du circuit électrique. Cette fonction permet donc de verrouiller l'ouvrant ouvert sans puissance électrique. Un tel ouvrant, verrouillé ouvert, restera verrouillé pendant et après le claquement de l'ouvrant. Mais la clé est en main et n'est donc pas piégée. Il en va de même si l'ouvrant en question est accessible à une condamnation par clef, la porte étant fermée. C'est le cas classique de la porte conducteur par exemple. Le verrouillage est effectué clé en main. Some of these locks are sometimes also equipped with a lock emergency function, which is operated by a mechanical interface of the key, which can be used only when the door is open, for the purpose of securing the vehicle when a failure of the electrical circuit. This function thus makes it possible to lock the open opening without electric power. Such an opening, locked open, will remain locked during and after the slamming of the opening. But the key is in hand and is not trapped. It is the same if the opening in question is accessible to a conviction by key, the door being closed. This is the classic case of the driver's door for example. The lock is made turnkey.
II existe aussi en Europe des modèles de véhicules équipées d'interface de condamnation mécanique utilisables sans clé. Dans ce cas, une serrure au moins par véhicule est équipée d'une fonction mécanique qui consiste à empêcher tout verrouillage dans la serrure si la serrure est ouverte. Cette fonction est communément appelée « interdiction de condamner porte ouverte ».  There are also models of vehicles in Europe equipped with a mechanical locking interface that can be used without a key. In this case, at least one lock per vehicle is equipped with a mechanical function which consists in preventing any lock in the lock if the lock is open. This function is commonly referred to as "prohibition of open door convictions".
Dans le cas d'un véhicule équipé de serrures « Self Lock », si le véhicule a les portes fermées, on peut bien sûr effectuer un verrouillage électrique du véhicule, soit par une commande du tableau de bord, soit par la télécommande de la clef. Dans le premier cas, on est à l'intérieur du véhicule avec la clé qui n'est donc pas piégée. Dans le deuxième cas, on a la clé en main et elle n'est pas piégée non plus.  In the case of a vehicle equipped with locks "Self Lock", if the vehicle has the doors closed, it is of course possible to perform an electric lock of the vehicle, either by a command of the dashboard or by the remote control of the key . In the first case, we are inside the vehicle with the key which is not trapped. In the second case, we have the key in hand and it is not trapped either.
Si le véhicule a une ou des portes ouverte(s), l'ordinateur de bord interdira généralement le pilotage en verrouillage de la porte ouverte ou de toutes les portes, pour éliminer le risque de sortir du véhicule en y oubliant la clef avant de fermer l'ouvrant. Cette fonction est une « interdiction de condamner porte ouverte » rendue électriquement.  If the vehicle has an open door (s), the on-board computer will generally prohibit the locking operation of the open door or all doors, to eliminate the risk of getting out of the vehicle by forgetting the key before closing opening. This function is an "open door condemnation ban" made electrically.
Une alternative souvent rencontrée consiste à autoriser le pilotage du verrouillage et à piloter aussitôt en déverrouillage. C'est « l'annulation de condamnation porte ouverte », rendue électriquement.  An alternative often encountered is to allow control of the lock and control immediately unlocking. This is the "open door conviction cancellation", made electrically.
En général, en Asie, il est souhaité qu'un ouvrant puisse rester verrouillé pendant l'ouverture de l'intérieur ou être verrouillé une fois ouvert. De ce fait, sur certaines serrures, une fonction mécanique d'annulation du verrouillage est prévue et est actionnée, lors du claquage de fermeture de l'ouvrant. Cette première fonction est couramment appelé « Cancel ». In general, in Asia, it is desired that an opening can remain locked during the opening of the interior or be locked once opened. As a result, on certain locks, a mechanical locking cancellation function is provided and is actuated during closing breakdown of the opening. This first function is commonly called "Cancel".
Le verrouillage pouvant être actionné, lorsque l'ouvrant est ouvert, une seconde fonction de confort est prévue qui permet qu'un ouvrant claqué en fermeture reste verrouillé après le claquage. Cette seconde fonction est couramment appelée « Key-Less-Lock ». Elle est utilisée afin de verrouiller le véhicule sans introduction ni actionnement de la clé. Elle est en général installée sur les ouvrants avant et fonctionne, lorsque la poignée extérieure est maintenue actionnée, lors de la fermeture par claquage de l'ouvrant.  The lock can be actuated, when the opening is opened, a second function of comfort is provided which allows a closing slammed door remains locked after the breakdown. This second function is commonly called "Key-Less-Lock". It is used to lock the vehicle without introduction or activation of the key. It is generally installed on the front opening and operates, when the outer handle is maintained actuated, when closing by slamming of the opening.
Une telle serrure est décrite dans le document de brevet GB 2 360 325.  Such a lock is described in GB 2 360 325.
La fonction « Cancel » y est réalisée au moyen d'un levier de transfert rotatif qui transforme le déplacement de fermeture d'une pièce couramment appelée faux cliquet solidaire du cliquet de la serrure, en un déplacement de déverrouillage d'un levier de verrouillage central. Pour ce faire, le faux cliquet comporte une bride poussant un bras du levier de transfert, qui tourne dans le sens horaire, et un tenon de ce levier de transfert se déplace dans une fente du levier de verrouillage central, de façon à ce que ce dernier tourne dans le sens contraire des aiguilles d'une montre, d'un état de verrouillage vers un état déverrouillé.  The "Cancel" function is carried out by means of a rotary transfer lever which transforms the closing movement of a part commonly called a false pawl integral with the ratchet of the lock into an unlocking movement of a central locking lever. . To do this, the false pawl comprises a flange pushing an arm of the transfer lever, which rotates clockwise, and a tenon of this transfer lever moves in a slot of the central locking lever, so that this last turns counterclockwise, from a lock state to an unlocked state.
La fonction « Key-Less-Lock » est réalisée par un désengagement du levier de transfert, lorsque le levier d'ouverture extérieure connecté à la poignée extérieure maintient le levier de verrouillage central dans sa position de verrouillage. La bride du faux cliquet mène alors le bras du levier de transfert qui tourne dans le sens horaire, le tenon de ce levier glissant alors librement dans la fente du levier de verrouillage central. Le levier de transfert travaille donc comme un inverseur de mouvement et requiert un axe de rotation supplémentaire et des éléments d'interface avec le levier de verrouillage central et le faux cliquet, à savoir la bride et le tenon. Il doit être en acier afin de résister et de transmettre l'énergie de claquage de l'ouvrant, lors de sa fermeture. The "Key-Less-Lock" function is achieved by disengaging the transfer lever, when the outer opening lever connected to the outer handle holds the central locking lever in its locking position. The flange of the pawl then leads the arm of the transfer lever which rotates clockwise, the tenon of this lever then sliding freely in the slot of the central locking lever. The transfer lever thus works as a motion inverter and requires an additional axis of rotation and interface elements with the central locking lever and the false pawl, namely the flange and the tenon. It must be made of steel in order to withstand and transmit the energy of the opening of the opening when it closes.
L'objet de l'invention est de fournir une serrure d'ouvrant de véhicule automobile comportant un mécanisme de fonction « Cancel » plus simple, plus léger et moins coûteux, sans nécessité de levier de transfert et donc comportant moins de pièces.  The object of the invention is to provide a motor vehicle door lock comprising a function mechanism "Cancel" simpler, lighter and less expensive, without the need for a transfer lever and therefore having fewer parts.
Pour ce faire, l'invention propose une serrure d'ouvrant de véhicule automobile comportant un pêne coopérant avec un cliquet, un levier de verrouillage central, un levier d'ouverture extérieur relié à une poignée extérieure, un levier de verrouillage intérieur relié à une commande de verrouillage intérieure ainsi qu'audit levier de verrouillage central, un faux cliquet étant solidaire dudit cliquet, serrure assurant une fonction de « Cancel » au moyen d'un agencement de transmission d'un déplacement de fermeture dudit faux cliquet en un déplacement de déverrouillage dudit levier de verrouillage central et caractérisée en ce que ledit agencement comporte un élément intégré audit levier de verrouillage central et disposé sur la trajectoire dudit faux cliquet lors d'une fermeture de l'ouvrant, ledit levier de verrouillage central se déplaçant de la position verrouillée à la position déverrouillée par coulissement selon une seule direction.  To do this, the invention proposes a motor vehicle door lock comprising a latch cooperating with a pawl, a central locking lever, an external opening lever connected to an external handle, an internal locking lever connected to a latch. internal locking control as well as central locking lever, a false pawl being integral with said pawl, lock providing a function of "Cancel" by means of a transmission arrangement of a closing movement of said pawl in a displacement of unlocking said central locking lever and characterized in that said arrangement comprises an element integrated in said central locking lever and disposed on the path of said false pawl upon closing of the opening, said central locking lever moving from the position locked to the unlocked position by sliding in one direction only.
Grâce à l'invention, la fonction « Cancel » est réalisée par une coopération par transmission directe du levier de verrouillage central et du faux cliquet, dans le sens où sont supprimés toute inversion de déplacements, toute amplification de déplacements et tout multi- con tacts. Selon un premier mode de réalisation, ledit agencement de transmission est un ressort. Thanks to the invention, the function "Cancel" is achieved by a direct transmission cooperation of the central locking lever and the false pawl, in the sense that any inversion of displacements, amplification of displacements and any multi-contacts are suppressed. . According to a first embodiment, said transmission arrangement is a spring.
De préférence, ledit ressort est un ressort de torsion et son dit élément une extrémité libre et recourbée de ce ressort.  Preferably, said spring is a torsion spring and said element a free end and bent of this spring.
Avantageusement, ledit ressort de torsion présente un axe central perpendiculaire à ladite direction de coulissement dudit levier de verrouillage central.  Advantageously, said torsion spring has a central axis perpendicular to said direction of sliding of said central locking lever.
Afin d'assurer également la fonction « Key-Less-Lock », ledit levier de verrouillage central comporte un doigt de coopération avec une bride dudit levier d'ouverture extérieure, l'actionnement de ce levier d'ouverture extérieure amenant ladite bride contre ledit doigt et bloquant ledit levier de verrouillage central en position verrouillée.  In order to also provide the "Key-Less-Lock" function, said central locking lever comprises a finger of cooperation with a flange of said external opening lever, the actuation of this external opening lever bringing said flange against said finger and locking said central locking lever in the locked position.
Selon un second mode de réalisation, ledit agencement de transmission est un tenon solidaire dudit levier de verrouillage central.  According to a second embodiment, said transmission arrangement is a tenon integral with said central locking lever.

Sur la figure 1, la serrure est en position ouverte et déverrouillée. Un actionnement électrique ou mécanique amène le levier de verrouillage central 1 vers le bas en position verrouillé, tel que représenté sur la figure 2.  In Figure 1, the lock is in the open position and unlocked. Electrical or mechanical actuation brings the central locking lever 1 down into the locked position, as shown in FIG. 2.
Lorsque l'ouvrant est fermé par claquage, dans cette position verrouillée, le pêne 5 de la serrure tourne et entraîne une rotation en cascade du cliquet 6 et du faux cliquet 3 qui est solidaire du cliquet 6. Ce dernier vient donc en contact avec l'extrémité libre recourbée 2A d'un ressort de torsion 2 intégré au levier de verrouillage central 1 et le pousse vers le haut. Le ressort en conséquence pousse vers le haut le levier de verrouillage central 1 jusqu'à la rotation maximale du pêne illustrée sur la figure 3. Dans cette position, la course du levier de verrouillage central 1 est à 2/3 de sa course totale.  When the door is closed by snapping, in this locked position, the bolt 5 of the lock rotates and causes a cascade rotation of the pawl 6 and the false pawl 3 which is secured to the pawl 6. The latter therefore comes into contact with the latch. curved free end 2A of a torsion spring 2 integrated in the central locking lever 1 and pushes it upwards. The spring accordingly pushes up the central locking lever 1 until the maximum rotation of the bolt shown in Figure 3. In this position, the stroke of the central locking lever 1 is 2/3 of its total stroke.
Plus précisément, le ressort de torsion 2 présente un axe central perpendiculaire à la direction de coulissement du levier de verrouillage central 1.  More specifically, the torsion spring 2 has a central axis perpendicular to the sliding direction of the central locking lever 1.
Le levier d'ouverture intermédiaire 7 libéré revient alors en position déverrouillée et la serrure est en état déverrouillé.  The released intermediate release lever 7 then returns to the unlocked position and the lock is in the unlocked state.
Puis le pêne 5 atteint sa position de demi-fermeture représentée sur la figure 4 et le cliquet 6 revient en position de repos. Ceci étant, le levier de verrouillage central 1 dépassant les 2/3 de sa course totale, un ressort bistable 8 uniquement représenté sur les figures 1 et 2 dans ses deux positions de stabilité correspondantes à la position déverrouillée et verrouillée de la serrure l'entraîne en position de bout de course et l'état de la serrure reste déverrouillé. Ce ressort bistable 8, de type par exemple cor de chasse, est de préférence connecté au levier de verrouillage intérieur 9 qui est relié bi-directionnellement au levier central de verrouillage 1 et en assure donc aussi la bistabilité. Then the bolt 5 reaches its half-closed position shown in Figure 4 and the pawl 6 returns to the rest position. However, since the central locking lever 1 exceeds two-thirds of its total stroke, a bistable spring 8 only shown in FIGS. 1 and 2 in its two stability positions corresponding to the unlocked and locked position of the lock causes it in end position and state the lock remains unlocked. This bistable spring 8, of the type for example flush horn, is preferably connected to the inner locking lever 9 which is bi-directionally connected to the central locking lever 1 and thus also ensures the bistability.
Ensuite, comme représenté sur les figures 5 et 6, le pêne continue sa rotation jusqu'à la position complètement fermée, sans autre action du ressort 2 et sans modification de l'état de la serrure.  Then, as shown in Figures 5 and 6, the bolt continues its rotation to the fully closed position, without further action of the spring 2 and without changing the state of the lock.
La fonction « Key-less-Lock » est également remplie grâce à cette serrure conforme à l'invention.  The "Key-less-Lock" function is also fulfilled thanks to this lock according to the invention.
Si l'on considère de nouveau la figure 1, la serrure est en position ouverte et déverrouillée. Un actionnement électrique ou mécanique amène le levier de verrouillage central 1 vers le bas en position verrouillée comme illustré sur la figure 2 ou 9. Le levier d'ouverture extérieure 4 est alors dans la position représentée sur la figure 7, non actionné.  If we consider again Figure 1, the lock is in the open position and unlocked. Electrical or mechanical actuation brings the central locking lever 1 down into the locked position as shown in FIG. 2 or 9. The external opening lever 4 is then in the position shown in FIG. 7, not actuated.
L'ouvrant étant donc verrouillé et ouvert, la poignée est actionnée et maintenue actionnée jusqu'à la fermeture de l'ouvrant. Le levier d'ouverture extérieure 4 est mû en rotation dans le sens horaire, comme visible sur la figure 8 et vient mettre en opposition sa bride 4A face à un doigt 1A porté par un tenon correspondant du levier central de verrouillage 1, comme également représenté sur la figure 9.  The opening being thus locked and open, the handle is actuated and maintained actuated until the closure of the opening. The outer opening lever 4 is rotated in the clockwise direction as shown in FIG. 8 and opposes its flange 4A facing a finger 1A carried by a corresponding tenon of the central locking lever 1, as also shown. in Figure 9.
Lors de la fermeture par claquage de l'ouvrant, le pêne 5 tourne comme visible sur la figure 10 et entraîne une rotation en cascade du cliquet 6 et du faux cliquet 3. Ce dernier vient alors en contact avec le ressort intégré 2 et le pousse vers le haut. Par contre, le levier de verrouillage central 1 n'est pas entraîné en déplacement vers le haut, puisque qu'il est bloqué par l'engagement de la bride 4A et du tenon 1A, la poignée étant maintenue actionnée. Le ressort 2 est donc déformé et courbé. Le maximum de rotation est alors généré, le levier d'ouverture intermédiaire 7 restant en position verrouillé, puis le pêne 5 atteint sa position de demi-fermeture représenté sur la figure 11, après lequel le cliquet 6 revient en position de repos. Le faux cliquet 3 libère alors le ressort bandé 2 qui revient à son état initial, sans que le levier central de verrouillage 1, qui est toujours maintenu en position verrouillé, ait changé d'état. When the shutter closes by closing, the bolt 5 rotates as shown in FIG. 10 and causes a cascade rotation of the pawl 6 and the false pawl 3. The latter then comes into contact with the integrated spring 2 and pushes it to the top. By cons, the central locking lever 1 is not driven upwardly, since it is blocked by the engagement of the flange 4A and the post 1A, the handle being maintained actuated. The spring 2 is thus deformed and curved. The maximum rotation is then generated, the intermediate opening lever 7 remaining in the locked position, then the bolt 5 reaches its half-closed position shown in Figure 11, after which the pawl 6 returns to the rest position. The false pawl 3 then releases the strip spring 2 which returns to its initial state, without the central locking lever 1, which is always held in the locked position, has changed state.
Le pêne 5 poursuit alors sa rotation jusqu'à son complet déplacement illustré sur la figure 12, sans modification de l'état verrouillé et par un autre cycle de bandage puis de libération du ressort 2.  The bolt 5 then continues its rotation until its complete displacement illustrated in FIG. 12, without modification of the locked state and by another cycle of tire then release of the spring 2.
Cet agencement conforme à invention rend facilement compatible les cinématiques des serrures de type Européen, avec les fonctions du type des serrures Asiatiques, et ce à moindre coût de composants.  This arrangement according to the invention makes the kinematics of European type locks easily compatible with the functions of the type of Asian locks, and at a lower cost of components.
Entre autres, la création d'une fonction « Override » peut se résumer à assurer une ouverture intérieure directe, sans souci de synchronisation de mouvement de déverrouillage, la fonction « Cancel » proposée, par l'ajout d'un simple petit ressort, assurant le déverrouillage lors du premier mouvement d'ouverture aussi bien que de fermeture de la serrure.  Among other things, the creation of an "Override" function can be summed up as ensuring a direct interior opening, without worry of synchronization of unlocking movement, the proposed "Cancel" function, by the addition of a simple small spring, ensuring unlocking during the first opening movement as well as closing the lock.
Une serrure de type « Override » reste compatible avec l'ajout de la fonction « Cancel » comme décrite ci-dessus, sans créer d'interférence cinématique.  An "Override" type lock remains compatible with the addition of the "Cancel" function as described above, without creating kinematic interference.
La fonction « Key-Less-Lock », rendue par simple ajout de l'interface 4A sur le levier d'ouverture extérieur, permet de fournir une fonction « secours de condamnation » sans ajout de composant ni d'accès à interface clé.  The "Key-Less-Lock" function, rendered simply by adding the 4A interface to the external opening lever, makes it possible to provide a "back-up" function without the addition of a component or key interface access.
La figure 13 représente un second mode de réalisation de l'invention. Selon cette variante, le précédent ressort 2 intégré au levier de verrouillage central 1 est remplacé par un tenon 2' solidaire du levier de verrouillage central 1, par exemple réalisé par moulage sur ce dernier, et perpendiculaire à la direction de coulissement du levier de verrouillage central 1. Figure 13 shows a second embodiment of the invention. According to this variant, the previous spring 2 integrated in the central locking lever 1 is replaced by a pin 2 'integral with the central locking lever 1, for example made by molding on the latter, and perpendicular to the sliding direction of the locking lever central 1.
La fonction « Cancel » s'opère alors de façon identique à celle déjà décrite, avec un composant de moins, mais la fonction « Key-Less- Lock » ne peut plus être remplie.  The "Cancel" function then operates identically to the one already described, with one component less, but the "Key-Less-Lock" function can no longer be fulfilled.
Nous retrouvons les mêmes avantages de compatibilité que ci- dessus vis-à-vis de la fonction « Override », mais on perd la possibilité du secours de condamnation sans interface spéciale.  We find the same advantages of compatibility as above vis-à-vis the function "Override", but we lose the possibility of condemnation assistance without special interface.
