Description

Serrure électrique à assistance de fermeture pour ouvrant de véhicule automobile Electric lock with closing assistance for opening of a motor vehicle
La présente invention concerne une serrure électrique à assistance de fermeture motorisée pour un ouvrant de véhicule automobile, notamment pour une portière, un hayon, une lunette de hayon ou le coffre d'un véhicule automobile.The present invention relates to an electric lock with motorized closing assistance for an opening of a motor vehicle, in particular for a door, a tailgate, a tailgate bezel or the trunk of a motor vehicle.
Les serrures électriques à assistance de fermeture motorisée classiques comportent un pêne à deux crans de fermeture, destiné à coopérer avec une gâche.The electric locks with conventional motorized closing assistance comprise a bolt with two notches closing, intended to cooperate with a striker.
Dans le processus de fermeture électrique assistée d'ouvrant de véhicule automobile, le pêne est entraîné en rotation pour assurer, une fois en prise avec la gâche, la fermeture de l'ouvrant et la compression du joint d'étanchéité entre l'ouvrant et la carrosserie.In the process of electric closing assisted motor vehicle opening, the bolt is rotated to ensure, once in engagement with the striker, the closure of the opening and the compression of the seal between the opening and the bodywork.
Pour entraîner le pêne depuis la position de fermeture au premier cran vers la position de fermeture au deuxième cran, les serrures comportent en outre un levier d'entraînement, embrayable avec le pêne, entraîné en pivotement par un actionneur électrique pouvant être déporté de la serrure.To drive the bolt from the closed position to the first notch to the closed position to the second notch, the locks further comprise a drive lever, engageable with the bolt, pivoted by an electric actuator can be deported from the lock .
En position d'ouverture de la serrure, le levier d'entraînement est débrayé du pêne pour permettre notamment, de préserver le fonctionnement de la serrure en cas de panne électrique, par exemple de l'actionneur.In the open position of the lock, the drive lever is disengaged from the bolt to allow, in particular, to preserve the operation of the lock in case of power failure, for example of the actuator.
A l'ouverture de la serrure, le pivotement du pêne est provoqué par la gâche ou par l'effort de réaction du joint.At the opening of the lock, the pivoting of the bolt is caused by the strike or the reaction force of the seal.
Ce pivotement entraîne le levier d'entraînement en rotation dans le sens de rotation opposé.This pivoting drives the rotary drive lever in the opposite direction of rotation.
Ces mécanismes d'assistance de fermeture motorisée peuvent cependant constituer une source de bruit non négligeable pour l'utilisateur. De plus, pour assurer un bon fonctionnement du mécanisme, il est également nécessaire d'assurer la fermeture de l'ouvrant dans un temps relativement court.These motorized closing assistance mechanisms can, however, constitute a significant source of noise for the user. In addition, to ensure proper operation of the mechanism, it is also necessary to ensure the closing of the opening in a relatively short time.
La présente invention vise à remédier à ces problèmes en proposant une serrure électrique perfectionnée dont le mécanisme d'assistance à la fermeture est amélioré, notamment par l'optimisation du temps nécessaire à la fermeture de l'ouvrant. A cet effet, l'invention prévoit une serrure électrique à assistance de fermeture pour ouvrant de véhicule automobile comportant:The present invention aims to remedy these problems by proposing an improved electric lock whose closure assistance mechanism is improved, in particular by optimizing the time required to close the door. For this purpose, the invention provides an electric lock with closing assistance for a motor vehicle opening comprising:
- un pêne comportant un premier et un deuxième cran, ledit pêne étant destiné à coopérer avec une gâche et étant apte à tourner entre une position ouverte, une position fermée au premier cran et une position fermée au deuxième cran de la serrure,a bolt comprising a first and a second notch, said bolt being intended to cooperate with a striker and being able to rotate between an open position, a closed position at the first notch and a closed position at the second notch of the lock,
- un cliquet pivotant apte à coopérer avec ledit pêne pour empêcher une rotation dudit pêne en position fermée au premier et au deuxième cran de la serrure,- A pivoting pawl adapted to cooperate with said bolt to prevent rotation of said bolt in the closed position at the first and second notch of the lock,
- un levier d'entraînement dudit pêne pour entraîner ledit pêne en rotation entre la position fermée au premier cran et la position fermée au deuxième cran de la serrure, caractérisée en ce que le levier d'entraînement comporte une protubérance agencée de sorte que ledit pêne soit apte à faire pivoter ledit levier lorsque ledit pêne tourne depuis la position ouverte vers la position fermée au premier cran de la serrure.a lever for driving said bolt for driving said bolt in rotation between the closed position at the first notch and the closed position at the second notch of the lock, characterized in that the driving lever comprises a protuberance arranged so that said bolt is able to rotate said lever when said bolt rotates from the open position to the closed position at the first notch of the lock.
D'autres avantages et caractéristiques apparaîtront à la lecture de la description de l'invention, ainsi que des figures suivantes sur lesquelles : - la figure 1 est une vue de coté de la serrure selon l'invention en position fermée,Other advantages and characteristics will appear on reading the description of the invention, as well as the following figures in which: FIG. 1 is a side view of the lock according to the invention in the closed position,
- la figure 2 est une vue intérieure du coté opposé de la serrure de la figure 1 en position ouverte, la figure 3 est une vue analogue à la figure 2, en position de fermeture au premier cran de la serrure, la figure 4 est une vue analogue à la figure 3, en position de fermeture au deuxième cran de la serrure,FIG. 2 is an inside view of the opposite side of the lock of FIG. 1 in the open position, FIG. 3 is a view similar to FIG. 2, in the closed position at the first notch of the lock, FIG. similar view to Figure 3, in the closed position at the second notch of the lock,
Sur toutes les figures, les éléments identiques portent les mêmes numéros de référence.In all the figures, the identical elements bear the same reference numbers.
La figure 1 représente une serrure électrique 1 à assistance de fermeture motorisée selon l'invention pour un ouvrant de véhicule automobile, notamment pour une portière, un hayon, une lunette de hayon ou le coffre de véhicule automobile.FIG. 1 represents an electric lock 1 with motorized closing assistance according to the invention for an opening of a motor vehicle, in particular for a door, a tailgate, a tailgate bezel or the trunk of a motor vehicle.
La serrure 1 comporte un boîtier 3 renfermant un pêne tournant 5 destiné à coopérer avec une gâche (non représentée). Pour entraîner le pêne 5 depuis la position de fermeture au premier cran vers la position de fermeture au deuxième cran, la serrure comporte un levier d'entraînement 9, embrayable avec le pêne 5, entraîné en pivotement par un actionneur électrique.The lock 1 comprises a housing 3 enclosing a latch bolt 5 intended to cooperate with a striker (not shown). To drive the bolt 5 from the closed position to the first notch to the closed position to the second notch, the lock comprises a drive lever 9, engageable with the bolt 5, pivotally driven by an electric actuator.
Etant donné que l'espace disponible au niveau de la serrure 1 est très limité, il est prévu de déporter l' actionneur grâce à un câble d'entraînement pour former un ensemble fonctionnel serrure-actionneur.Since the space available at the lock 1 is very limited, it is intended to deport the actuator through a drive cable to form a lock actuator operating unit.
Ainsi, on aperçoit sur la figure 1, un premier bras 7 du levier d'entraînement 9 comportant un orifice 11 pour relier le levier 9 au câble d'entraînement de l'actionneur électrique (non représenté). Sur la figure 2, on a représenté l'intérieur du boîtier 3 de la serrure 1 comportant le pêne 5, un cliquet 13 et le levier d'entraînement 9.Thus, it can be seen in Figure 1, a first arm 7 of the driving lever 9 having an orifice 11 for connecting the lever 9 to the drive cable of the electric actuator (not shown). FIG. 2 shows the interior of the housing 3 of the lock 1 comprising the bolt 5, a pawl 13 and the driving lever 9.
Le pêne 5, susceptible de tourner autour de l'axe de rotation 15, possède un logement 17, destiné à recevoir la gâche qui coopère avec la serrure 1.The bolt 5, rotatable about the axis of rotation 15, has a housing 17 for receiving the keeper which cooperates with the lock 1.
Le pêne 5 présente deux crans d'arrêt 19 et 20 définissant deux positions de fermeture d ' un ouvrant .The bolt 5 has two detents 19 and 20 defining two closing positions of an opening.
Les deux crans 19 et 20 sont destinés à coopérer avec une extrémité en forme de bec 22 du cliquet 13 pour empêcher la rotation du pêne 5.The two notches 19 and 20 are intended to cooperate with a spout-shaped end 22 of the pawl 13 to prevent rotation of the bolt 5.
Le cliquet 13 est soumis à une force de rappel élastique, qui le sollicite vers le pêne 5. On prévoit que le cliquet 13 est solidaire en pivotement d'un entraîneur 26 lui- même entraîné par un actionneur d'ouverture de la serrure (non représenté).The pawl 13 is subjected to an elastic restoring force, which urges it towards the bolt 5. It is anticipated that the pawl 13 is pivotally integral with a driver 26 itself driven by an actuator for opening the lock (no represent).
L'entraîneur 26 est susceptible de pivoter avec le cliquet 13 autour d'un axe de rotation 24.The driver 26 is pivotable with the pawl 13 about an axis of rotation 24.
Ainsi, le pêne 5 peut pivoter entre une position ouverte (figure 2), une position fermée au premier cran (figure 3) et une position fermée au deuxième cran (figure 4) de la serrure 1.Thus, the bolt 5 can pivot between an open position (Figure 2), a closed position to the first notch (Figure 3) and a closed position to the second notch (Figure 4) of the lock 1.
Dans la position fermée au premier cran représentée sur la figure 3, le cliquet 13 vient prendre appui par son bec d'extrémité 22 contre le premier cran 19. De la sorte, la gâche est emprisonnée dans le logement 17, ce qui maintient la porte en état de fermeture. Puis, dans la position de fermeture au deuxième cran, représentée sur la figure 4, le bec d'extrémité 22 du cliquet 13 prend appui contre le deuxième cran 20 du pêne 5.In the closed position to the first notch shown in Figure 3, the pawl 13 is supported by its end nose 22 against the first notch 19. In this way, the striker is trapped in the housing 17, which holds the door in the closed state. Then, in the closed position at the second notch, shown in FIG. 4, the end nose 22 of the pawl 13 bears against the second catch 20 of the bolt 5.
Selon l'invention, le levier d'entraînement 9 comporte une protubérance 37 agencée de sorte que le pêne 5 soit apte à faire pivoter le levier 9 lorsque le pêne 5 tourne depuis la position ouverte vers la position fermée au premier cran de la serrure.According to the invention, the driving lever 9 comprises a protuberance 37 arranged so that the bolt 5 is able to rotate the lever 9 when the bolt 5 rotates from the open position to the closed position at the first notch of the lock.
Le pivotement du levier 9 lui permet de s'embrayer avec le pêne pour l'entraîner vers la position de fermeture au deuxième cran.The pivoting of the lever 9 allows it to engage with the bolt to drive it to the closed position to the second notch.
Pour cela et comme on le distingue sur la figure 2, le levier 9 comporte un deuxième bras 29 portant la protubérance 37, destinée à coopérer avec un organe d'actionnement 33 solidaire en rotation du pêne 5.For this and as can be seen in FIG. 2, the lever 9 comprises a second arm 29 carrying the protuberance 37, intended to cooperate with an actuating member 33 integral in rotation with the bolt 5.
Le levier 9 est ainsi articulé autour d'un axe de rotation 10.The lever 9 is thus articulated around an axis of rotation 10.
Une force de rappel élastique le sollicite dans une position débrayée à l'écart du pêne 5 en position ouverte de la serrure.An elastic restoring force urges it into a disengaged position away from the bolt 5 in the open position of the lock.
De façon avantageuse, la protubérance 37 est formée dans une première branche qui forme une fourche 31 avec une deuxième branche 39, à l'extrémité libre du deuxième bras 29 du levier 9.Advantageously, the protrusion 37 is formed in a first branch which forms a fork 31 with a second branch 39, at the free end of the second arm 29 of the lever 9.
Préférentiellement, la fourche 31 est apte à coopérer avec une excroissance associée portée par l'organe d'actionnement 33.Preferably, the fork 31 is able to cooperate with an associated protrusion carried by the actuating member 33.
Ainsi, la première branche 37 est apte à être entraînée en pivotement par le pêne 5 lorsque le pêne 5 tourne depuis la position ouverte vers la position fermée au premier cran de la serrure.Thus, the first branch 37 is adapted to be pivoted by the bolt 5 when the bolt 5 rotates from the open position to the closed position at the first notch of the lock.
En outre, la deuxième branche 39 est apte à entraîner en rotation l'excroissance 35 du pêne 5 entre la position fermée au premier cran et la position fermée au deuxième cran de la serrure. Selon un mode de réalisation particulier de l'invention, la serrure 1 comporte un premier capteur de position 43 pour déterminer la position fermée au deuxième cran de la serrure.In addition, the second branch 39 is able to rotate the protrusion 35 of the bolt 5 between the closed position to the first notch and the closed position to the second notch of the lock. According to a particular embodiment of the invention, the lock 1 comprises a first position sensor 43 to determine the closed position at the second notch of the lock.
Avantageusement, le premier capteur 43 est placé au niveau du levier d'entraînement 9, de manière à être activé lorsque le levier d'entraînement 9 pivote. Ainsi, le capteur 43 est activé lorsque le levier 9 a pivoté depuis la position fermée au premier cran vers la position fermée au deuxième cran de la serrure 1.Advantageously, the first sensor 43 is placed at the level of the driving lever 9, so as to be activated when the driving lever 9 pivots. Thus, the sensor 43 is activated when the lever 9 has pivoted from the closed position to the first notch to the closed position to the second notch of the lock 1.
Un deuxième capteur de position 45 de la serrure 1 apte à déterminer une position active de retenue du pêne 5 par le cliquet 13, est placé au niveau de l'entraîneur 26 du cliquet 13.A second position sensor 45 of the lock 1 capable of determining an active position for retaining the bolt 5 by the pawl 13 is placed at the level of the driver 26 of the pawl 13.
Ce capteur 45 est activé lorsque le cliquet 13 est en position active de retenue du pêne 5 en position fermée au premier ou deuxième cran de la serrure 1.This sensor 45 is activated when the pawl 13 is in the active position of retaining the bolt 5 in the closed position at the first or second notch of the lock 1.
On prévoit de relier les capteurs de position 43 et 45 à une unité de traitement (non visible), apte à piloter l'entraînement du pêne 5 par le levier d'entraînement 9 lorsque la serrure 1 est fermée au premier cran.It is expected to connect the position sensors 43 and 45 to a processing unit (not visible), able to control the driving of the bolt 5 by the drive lever 9 when the lock 1 is closed at the first notch.
Ainsi, l'unité de traitement pilote l'entraînement du pêne 5 par le levier 9 lorsque le deuxième capteur de position 45 du cliquet est activé et le premier capteur 43 du levier 9 est désactivé.Thus, the processing unit drives the driving of the bolt 5 by the lever 9 when the second position sensor 45 of the pawl is activated and the first sensor 43 of the lever 9 is deactivated.
L'entraînement est stoppé lorsque les deux capteurs 43 et 45 sont activés. Partant de la position initiale ouverte de l'ouvrant de la figure 2, et en considérant maintenant les figures 3 à 4, on décrit maintenant le fonctionnement de la serrure électrique.The drive is stopped when both sensors 43 and 45 are activated. Starting from the open initial position of the opening of FIG. 2, and now considering FIGS. 3 to 4, the operation of the electric lock is now described.
En position initiale ouverte, les capteurs de position 43 et 45 sont désactivés.In the initial open position, the position sensors 43 and 45 are deactivated.
La fermeture de l'ouvrant au premier cran de la figure 3 est assurée par la rotation du pêne 5 dans le sens horaire comme schématisé par la flèche 47.The closure of the opening to the first step of Figure 3 is ensured by the rotation of the bolt 5 clockwise as shown schematically by the arrow 47.
L'organe d'actionnement 33, solidaire en rotation du pêne 5, tourne également dans le sens horaire indiqué par la flèche 47.The actuating member 33, integral in rotation with the bolt 5, also rotates in the clockwise direction indicated by the arrow 47.
Le cliquet 13 et l'entraîneur de cliquet 26, sollicités élastiquement à l'encontre du pêne 5 pivotent dans le sens horaire, comme représenté par la flèche 49 sur la figure 3. Au cours de la rotation du pêne 5, la première branche 37 du levier 9 entre en contact avec l'excroissance 35 de l'organe d'actionnement 33.The pawl 13 and the pawl driver 26 resiliently biased against the bolt 5 rotate clockwise, as shown by the arrow 49 in FIG. 3. During the rotation of the bolt 5, the first branch 37 the lever 9 comes into contact with the protrusion 35 of the actuating member 33.
Puis, l'excroissance 35 entraîne le levier 9 dans le sens antihoraire vers sa position embrayée avec le pêne 5, comme schématisé par la flèche 51, plaçant le levier 9 dans la course utile de l'actionneur du levier 9. Ainsi, le déplacement de l'actionneur est susceptible de provoquer immédiatement le déplacement du levier d'entraînement 9, sans course à vide et donc sans perte de temps.Then, the protrusion 35 drives the lever 9 counterclockwise to its engaged position with the bolt 5, as shown by the arrow 51, placing the lever 9 in the operating stroke of the lever actuator 9. Thus, the displacement of the actuator is capable of immediately causing the movement of the driving lever 9, without a vacuum stroke and therefore without loss of time.
En fin de pivotement du pêne 5 dans la position de fermeture au premier cran, l'extrémité du crochet 22 du cliquet 13 vient en appui sur le premier cran 19 du pêne 5, empêchant le pêne 5 de tourner dans le sens de rotation antihoraire.At the end of pivoting of the bolt 5 in the closed position to the first notch, the end of the hook 22 of the pawl 13 bears on the first notch 19 of the bolt 5, preventing the bolt 5 from rotating in the anticlockwise rotation direction.
Ainsi, l'ouverture de l'ouvrant est bloquée par la fermeture de la serrure au premier cran.Thus, the opening of the opening is blocked by closing the lock at the first notch.
Le premier capteur de position 43 est toujours désactivé tandis que le deuxième capteur de position 45 de retenue du pêne 5 est activé.The first position sensor 43 is always deactivated while the second position sensor 45 for retaining the bolt 5 is activated.
L'unité de traitement pilote alors le levier d'entraînement 9, via l'actionneur électrique déporté, dans le sens antihoraire, comme schématisé par la flèche 53 sur la figure 4.The processing unit then drives the driving lever 9, via the remote electric actuator, counterclockwise, as shown schematically by the arrow 53 in FIG. 4.
La deuxième branche 39 de la fourche 31 entre alors rapidement en contact avec l'excroissance 35 du pêne 5 pour l'entraîner en rotation dans le sens horaire de la flèche 47 vers la position fermée au deuxième cran de la serrure 1.The second branch 39 of the fork 31 then quickly comes into contact with the protrusion 35 of the bolt 5 to cause it to rotate clockwise from the arrow 47 to the closed position at the second detent of the lock 1.
En fin de pivotement du pêne 5 dans la position de fermeture au deuxième cran, l'extrémité du crochet 22 du cliquet 13 vient en appui sur le deuxième cran 20 du pêne 5. Le premier capteur 43 de position de fermeture au deuxième cran de la serrure est alors activé et l'unité de traitement stoppe l'entraînement du pêne 5 par le levier 9.At the end of pivoting of the bolt 5 in the closed position at the second notch, the end of the hook 22 of the pawl 13 bears on the second catch 20 of the bolt 5. The first sensor 43 of the closed position at the second notch of the lock is then activated and the processing unit stops the driving of the bolt 5 by the lever 9.
Ainsi, le pêne 5 ne peut plus tourner dans le sens de rotation antihoraire, ce qui assure la fermeture de la serrure 1 au deuxième cran.Thus, the bolt 5 can no longer rotate in the anticlockwise rotation direction, which ensures the closure of the lock 1 to the second notch.
Lorsque l'utilisateur ouvre la serrure 1, la rotation du pêne 5 provoqué par la gâche ou par l'effort de réaction du joint élastique, entraîne le levier 9 dans le sens de rotation opposé.When the user opens the lock 1, the rotation of the bolt 5 caused by the striker or by the reaction force of the elastic seal, drives the lever 9 in the opposite direction of rotation.
L'entraînement est assuré par l'action de l'excroissance 35 sur la deuxième branche 39 jusqu'à ce que le levier 9 s'échappe de l'excroissance 35, se retrouvant ainsi en position débrayée du pêne 5. Le levier 9 bascule alors dans la position initiale illustrée sur la figure 2 à l'écart du pêne 5 par la force de rappel élastique.The drive is ensured by the action of the protrusion 35 on the second branch 39 until the lever 9 escapes from the protrusion 35, thus finding itself in the disengaged position of the bolt 5. The lever 9 then switches to the initial position shown in Figure 2 away from the bolt 5 by the elastic return force.
La présente invention permet donc l'optimisation du temps nécessaire à la fermeture de l'ouvrant. En effet, l'entraînement du levier 9 par le pêne 5, lorsque celui-ci tourne vers la position de fermeture au premier cran, a pour effet de pré-positionner le levier 9 en position active, réduisant la course du levier 9.The present invention thus allows the optimization of the time required for closing the door. Indeed, the driving of the lever 9 by the bolt 5, when it turns towards the closed position at the first notch, has the effect of pre-positioning the lever 9 in the active position, reducing the travel of the lever 9.
Ainsi le levier 9 est en mesure d'entraîner le pêne 5 dès que le pêne 5 atteint la position de fermeture au premier cran, sans perte de temps due au parcours du levier 9 vers sa position embrayée.Thus the lever 9 is able to drive the bolt 5 as soon as the bolt 5 reaches the closed position at the first notch, without loss of time due to the travel of the lever 9 to its engaged position.
La diminution du temps d'actionnement a également pour effet de réduire la durée de motorisation de l'actionneur, réduisant le bruit généré par celui-ci.Reducing the actuation time also has the effect of reducing the actuator's operating time, reducing the noise generated by the actuator.
D'autre part, ce mécanisme est simple de réalisation et peu encombrant, ce qui permet de libérer de l'espace dans le boîtier 3 de la serrure 1 permettant l'intégration des capteurs de position pour assurer l'automatisation de la fonction de fermeture assistée au deuxième cran.On the other hand, this mechanism is simple and compact, which allows free space in the housing 3 of the lock 1 allowing the integration of position sensors to ensure the automation of the closure function assisted at the second notch.
On comprend qu'avec une serrure électrique 1 à assistance de fermeture motorisée comportant une protubérance 37 du levier d'entraînement 9 agencée pour entraîner le levier 9 en pivotement vers sa position embrayée avec le pêne 5 lorsque le pêne 5 tourne depuis la position ouverte vers la position fermée au premier cran de la serrure 1 permet d'optimiser le temps nécessaire à la fermeture de l'ouvrant par un pré-positionnement efficace du levier d'entraînement 9. It is understood that with an electric lock 1 with motorized closing assistance having a protrusion 37 of the driving lever 9 arranged to drive the lever 9 pivotally to its engaged position with the bolt 5 when the bolt 5 rotates from the open position towards the closed position at the first notch of the lock 1 optimizes the time required to close the opening by an effective pre-positioning of the driving lever 9.
