Description

L'invention concerne un mécanisme de verrouillage électrique d'un ouvrant de véhicule automobile et plus particulièrement d'un ouvrant arrière, tel qu'un coffre, de véhicule automobile.The invention relates to an electric locking mechanism for an opening of a motor vehicle and more particularly of a rear opening, such as a trunk, of a motor vehicle.

Les fonctions de verrouillage et/ou de fermeture électrique, avec assistance de fermeture des ouvrants sont de plus en plus fréquentes sur des hayons de véhicule. L'utilisateur peut ainsi à distance commander l'ouverture et la fermeture de son hayon. Des vérins électriques réalisent l'ouverture et la fermeture du hayon, alors qu'une serrure réalise la fermeture ou l'ouverture de l'ouvrant.Electric locking and / or closing functions, with assistance for closing the doors, are more and more frequent on vehicle tailgates. The user can thus remotely control the opening and closing of his tailgate. Electric jacks perform the opening and closing of the tailgate, while a lock performs the closing or opening of the opening.

Les serrures à assistance électriques d'ouverture ou de fermeture, réalisent la fonction à l'aide d'un actionneur qui pilote soit un cliquet pour ouvrir soit un pêne pour fermer l'ouvrant.Electrically assisted opening or closing locks perform the function using an actuator which controls either a pawl to open or a bolt to close the opening.

Dans le cas où un élément du mécanisme de verrouillage électrique est défaillant, par exemple une perte de tension, un moteur grillé ou un moteur rouillé, il n'est plus possible de piloter électriquement la serrure et il devient nécessaire de réaliser une fonction de secours mécanique.In the event that an element of the electric locking mechanism is faulty, for example a loss of voltage, a burnt out motor or a rusted motor, it is no longer possible to control the lock electrically and it becomes necessary to perform an emergency function. mechanical.

Concernant l'ouverture, il est connu de piloter directement ou indirectement le cliquet pour le faire basculer et ouvrir la serrure.Regarding the opening, it is known to directly or indirectly control the pawl to tilt it and open the lock.

Pour la fermeture, il existe une solution de déblocage mécanique ou électromécanique par friction, qui permet de tirer sur le pêne afin de désaccoupler le pêne du mécanisme de verrouillage électrique pour libérer ce dernier.For closing, there is a mechanical or electromechanical friction release solution, which allows the bolt to be pulled in order to disconnect the bolt from the electric locking mechanism to release the latter.

Cependant, cette solution présente de nombreux inconvénients car elle est complexe et coûteuse à mettre en place.However, this solution has many drawbacks because it is complex and expensive to implement.

Finalement, beaucoup de produits ne présentent pas de solution de secours mécanique.Finally, many products do not have a mechanical back-up solution.

Il existe donc un risque que la serrure reste bloquée. L'utilisateur peut croire que la serrure est fermée, c'est-à-dire que le cliquet bloque le pêne, alors que ce n'est en fait le moteur bloqué qui empêche le pêne de pivoter.There is therefore a risk that the lock will remain blocked. The user may believe that the lock is closed, that is to say that the pawl is blocking the bolt, when it is in fact the blocked motor which is preventing the bolt from rotating.

L'invention vise à résoudre au moins un des inconvénients précités en fournissant un mécanisme de verrouillage d'un ouvrant de véhicule automobile comprenant :

  • une serrure de verrouillage de l'ouvrant comprenant un cliquet et un pêne configuré pour coopérer de façon à permettre le verrouillage ou le déverrouillage de l'ouvrant ;
  • un actionneur électrique ;
  • un agencement de transmission configuré pour transmettre un mouvement de l'actionneur électrique au pêne en vue du déplacement du pêne de la serrure entre une position de déverrouillage dans laquelle le pêne est libéré du cliquet et une position de verrouillage dans laquelle le pêne est bloqué par le cliquet ;
l'agencement de transmission comprenant :
  • un organe de transmission aval configuré pour transmettre un mouvement au pêne,
  • un organe de transmission amont configuré pour transmettre un mouvement de l'actionneur à l'organe de transmission aval; et
  • un organe de blocage mobile par rapport à l'organe de transmission aval et/ou l'organe de transmission amont, l'organe de blocage étant configuré pour définir avec l'organe de transmission amont et/ou l'organe de transmission aval :
  • une position de blocage relatif dans laquelle l'organe de blocage coopère avec l'organe de transmission amont et/ou l'organe de transmission aval de manière à permettre la transmission d'un mouvement entre l'organe de transmission amont et l'organe de transmission aval, et
  • une position de déblocage relatif dans laquelle l'organe de blocage est mobile selon au moins un degré de liberté par rapport à l'organe de transmission amont et/ou l'organe de transmission aval.
The invention aims to resolve at least one of the aforementioned drawbacks by providing a locking mechanism for an opening of a motor vehicle comprising:
  • a lock for locking the opening comprising a pawl and a bolt configured to cooperate so as to allow the locking or unlocking of the opening;
  • an electric actuator;
  • a transmission arrangement configured to transmit movement of the electric actuator to the bolt for movement of the bolt of the lock between an unlocked position in which the bolt is released from the pawl and a locked position in which the bolt is locked by the ratchet;
the transmission arrangement comprising:
  • a downstream transmission member configured to transmit movement to the bolt,
  • an upstream transmission member configured to transmit movement from the actuator to the downstream transmission member; and
  • a movable locking member relative to the downstream transmission member and / or the upstream transmission member, the locking member being configured to define with the upstream transmission member and / or the downstream transmission member:
  • a relative locking position in which the locking member cooperates with the upstream transmission member and / or the downstream transmission member so as to allow the transmission of a movement between the upstream transmission member and the member downstream transmission, and
  • a relative unlocking position in which the locking member is movable according to at least one degree of freedom with respect to the upstream transmission member and / or the downstream transmission member.

Ce mécanisme de verrouillage permet donc d'être manipulé aisément en cas de défaillance électrique du véhicule, notamment par l'agencement de transmission de ce mécanisme de verrouillage.This locking mechanism therefore makes it possible to be easily handled in the event of an electrical failure of the vehicle, in particular by the transmission arrangement of this locking mechanism.

Par verrouillage, on peut entendre également fermeture, en particulier un verrouillage ou une fermeture électrique. De la même façon, par déverrouillage on peut entendre ouverture, en particulier un déverrouillage ou une ouverture électrique.By locking, one can also understand closure, in particular an electric locking or closing. Likewise, by unlocking we can understand opening, in particular unlocking or electric opening.

Au sens de l'invention, le fait que l'organe de blocage est mobile selon au moins un degré de liberté par rapport à l'organe de transmission amont et/ou l'organe de transmission aval dans la position de déblocage relatif signifie qu'il existe au moins un degré de liberté supplémentaire entre l'organe de blocage et l'organe de transmission amont et/ou l'organe de transmission aval dans la position de déblocage relatif par rapport à la position de blocage relatif.Within the meaning of the invention, the fact that the locking member is movable according to at least one degree of freedom with respect to the upstream transmission member and / or the downstream transmission member in the relative unlocking position means that 'there is at least one additional degree of freedom between the locking member and the upstream transmission member and / or the downstream transmission member in the relative unlocking position with respect to the relative locking position.

On comprend que l'agencement de transmission est formé par une chaîne de transmission comprenant l'organe de transmission amont, l'organe de blocage, et l'organe de transmission aval. Autrement dit, la chaîne de transmission comprend l'organe de blocage.It is understood that the transmission arrangement is formed by a transmission chain comprising the upstream transmission member, the locking member, and the downstream transmission member. In other words, the transmission chain includes the blocking member.

Dans la position de déblocage relatif, l'organe de transmission amont et l'organe de transmission aval ne sont plus engagés l'un avec l'autre.In the relative unlocking position, the upstream transmission member and the downstream transmission member are no longer engaged with each other.

On comprend que l'un de l'organe de transmission amont et l'organe de transmission aval est relié de manière permanente à l'organe de blocage. L'autre de l'organe de transmission amont et de l'organe de transmission aval est relié de manière amovible à l'organe de blocage.It will be understood that one of the upstream transmission member and the downstream transmission member is permanently connected to the locking member. The other of the upstream transmission member and of the downstream transmission member is removably connected to the locking member.

En particulier, dans la position de blocage relatif, l'organe de blocage est relié à l'organe de transmission amont et à l'organe de transmission aval.In particular, in the relative blocking position, the blocking member is connected to the upstream transmission member and to the downstream transmission member.

Par exemple, dans la position de déblocage relatif, l'organe de blocage est relié à l'organe de transmission amont et désengagé de l'organe de transmission aval ou l'organe de blocage est relié à l'organe de transmission aval et désengagé de l'organe de transmission amont.For example, in the relative unlocking position, the locking member is connected to the upstream transmission member and disengaged from the downstream transmission member or the locking member is connected to the downstream transmission member and disengaged of the upstream transmission unit.

On entend par « relié », que l'organe de blocage est engagé ou coopère avec l'organe de transmission amont et/ou l'organe de transmission aval de sorte à permettre ou non la transmission d'un mouvement de l'actionneur vers le pêne.The term “connected” is understood to mean that the blocking member is engaged or cooperates with the upstream transmission member and / or the downstream transmission member so as to allow or not the transmission of a movement from the actuator to the bolt.

L'organe de blocage peut être relié à l'organe de transmission amont directement ou indirectement.The locking member can be connected to the upstream transmission member directly or indirectly.

L'organe de blocage peut être relié à l'organe de transmission aval directement ou indirectement.The blocking member can be connected to the downstream transmission member directly or indirectly.

On comprend que l'actionneur est configuré pour déplacer le pêne dans une position de verrouillage, dans laquelle le pêne coopère avec le cliquet de sorte à verrouiller l'ouvrant.It will be understood that the actuator is configured to move the bolt into a locking position, in which the bolt cooperates with the pawl so as to lock the opening.

On comprend que l'actionneur est configuré pour déplacer le pêne dans une position de déverrouillage, dans laquelle le pêne est libéré du cliquet de sorte à déverrouiller l'ouvrant.It will be understood that the actuator is configured to move the bolt into an unlocking position, in which the bolt is released from the pawl so as to unlock the opening.

Par exemple, le mécanisme de verrouillage comprend un élément de rappel, configuré pour rappeler le pêne dans la position de déverrouillage.For example, the locking mechanism includes a return element, configured to return the bolt to the unlocked position.

Ainsi, dans la position de déblocage relatif, lorsque l'organe de transmission amont et l'organe de transmission aval sont désengagés, l'élément de rappel rappelle le pêne dans la position de déverrouillage et l'ouvrant est déverrouillé.Thus, in the relative unlocking position, when the upstream transmission member and the downstream transmission member are disengaged, the return element returns the bolt to the unlocking position and the opening is unlocked.

Par exemple, l'élément de rappel est un ressort. Par exemple l'élément de rappel est une lame élastique telle qu'une lame métallique.For example, the return element is a spring. For example, the return element is an elastic strip such as a metal strip.

Selon une possibilité, l'organe de blocage est relié à un système de secours mécanique, le système de secours mécanique étant configuré pour déclencher un passage entre la position de blocage relatif et la position de déblocage relatif de l'organe de blocage et de l'organe de transmission amont et/ou l'organe de transmission aval.According to one possibility, the blocking member is connected to a mechanical emergency system, the mechanical emergency system being configured to trigger a passage between the relative locking position and the relative unlocking position of the locking member and of the upstream transmission member and / or downstream transmission member.

Le système de secours mécanique permet de désaccoupler l'agencement de transmission afin de solutionner la défaillance électrique contrairement à l'art antérieur où le pêne devait être désaccouplé du mécanisme.The mechanical back-up system makes it possible to decouple the transmission arrangement in order to resolve the electrical failure, unlike the prior art where the bolt had to be uncoupled from the mechanism.

En particulier, le système de secours mécanique peut être actionné manuellement par un utilisateur, afin de déplacer l'organe de blocage et de désengager l'organe de transmission aval de l'organe de transmission amont, se trouvant alors dans la position de déblocage relatif.In particular, the mechanical emergency system can be actuated manually by a user, in order to move the locking member and to disengage the downstream transmission member from the upstream transmission member, then being in the relative unlocking position. .

Selon une possibilité, l'organe de blocage comprend une surface de came configurée pour déplacer l'organe de blocage sous l'effet d'une poussée de l'organe de transmission amont et/ou de l'organe de transmission aval de façon à positionner l'organe de transmission amont et/ou l'organe de transmission aval et l'organe de blocage dans la position de blocage relatif.According to one possibility, the locking member comprises a cam surface configured to move the locking member under the effect of a thrust from the upstream transmission member and / or the downstream transmission member so as to position the upstream transmission member and / or the downstream transmission member and the locking member in the relative locking position.

Une fois la défaillance électrique réparée, le mécanisme de verrouillage peut être réarmer pour verrouiller électriquement l'ouvrant.Once the electrical fault has been repaired, the locking mechanism can be reset to electrically lock the sash.

On comprend que l'organe de blocage, l'organe de transmission amont et l'organe de transmission aval sont configurés pour passer de la position de déblocage relatif à la position de blocage relatif. Le passage de la position de déblocage relatif à la position de blocage relatif peut être réalisé par glissement de l'organe de transmission amont ou l'organe de transmission aval contre la surface de came de l'organe de blocage. L'organe de transmission amont ou l'organe de transmission aval peut être déplacé manuellement contre la surface de came de l'organe de blocage.It is understood that the locking member, the upstream transmission member and the downstream transmission member are configured to go from the relative unlocking position to the relative locking position. The passage from the relative unlocking position to the relative locking position can be achieved by sliding the upstream transmission member or the downstream transmission member against the cam surface of the locking member. The upstream transmission member or the downstream transmission member can be moved manually against the cam surface of the locking member.

Selon une autre possibilité, l'organe de transmission aval comprend une surface de came configurée pour guider l'organe de blocage par rapport à l'organe de transmission aval sous l'effet d'une rotation de l'organe de transmission amont de façon à positionner l'organe de transmission amont et l'organe de blocage dans la position de blocage relatif.According to another possibility, the downstream transmission member comprises a cam surface configured to guide the locking member relative to the downstream transmission member under the effect of a rotation of the upstream transmission member so in positioning the upstream transmission member and the locking member in the relative locking position.

Selon une autre possibilité, l'organe de blocage est mobile entre une position d'ouverture dans laquelle l'organe de transmission amont et/ou l'organe de transmission aval peut passer de la position de blocage relatif à la position de déblocage relatif et une position de fermeture dans laquelle l'organe de blocage s'oppose au passage de la position de blocage à la position de déblocage.According to another possibility, the locking member is movable between an open position in which the upstream transmission member and / or the downstream transmission member can pass from the relative locking position to the relative unlocking position and a closed position in which the locking member opposes the passage from the locking position to the unlocking position.

Ainsi, l'organe de blocage et l'organe de transmission amont et/ou l'organe de transmission aval sont désaccouplés pour réparer la défaillance électrique.Thus, the locking member and the upstream transmission member and / or the downstream transmission member are uncoupled to repair the electrical failure.

Selon une possibilité, l'organe de blocage comprend une surface de contact configurée pour entrer en contact avec l'organe de transmission amont et/ou l'organe de transmission aval, l'organe de blocage étant guidé entre la position de fermeture et la position d'ouverture selon une trajectoire comprise dans le plan de la surface de contact.According to one possibility, the locking member comprises a contact surface configured to come into contact with the upstream transmission member and / or the downstream transmission member, the locking member being guided between the closed position and the opening position along a path included in the plane of the contact surface.

La surface de contact permet de réduire les efforts nécessaires à désaccoupler l'organe de transmission amont et/ou l'organe de transmission aval et l'organe de blocage.The contact surface makes it possible to reduce the efforts required to disconnect the upstream transmission member and / or the downstream transmission member and the locking member.

Selon une possibilité, l'organe de blocage est mobile en rotation autour d'un axe de rotation, la surface de contact étant orientée perpendiculairement à un segment reliant l'axe de rotation à ladite surface.According to one possibility, the locking member is movable in rotation about an axis of rotation, the contact surface being oriented perpendicularly to a segment connecting the axis of rotation to said surface.

Selon une possibilité, l'organe de transmission aval et/ou l'organe de transmission amont comprend un moyen de rappel configuré pour exercer une force de rappel sur l'organe de blocage vers la position de fermeture dudit organe de blocage.According to one possibility, the downstream transmission member and / or the upstream transmission member comprises a return means configured to exert a return force on the locking member towards the closed position of said locking member.

Par exemple, le moyen de rappel est un ressort. Par exemple le moyen de rappel est une lame élastique, telle qu'une lame métallique.For example, the return means is a spring. For example, the return means is an elastic blade, such as a metal blade.

Selon une possibilité, l'organe de transmission aval et/ou l'organe de transmission amont comprend une butée configurée pour bloquer l'organe de blocage en position de fermeture.According to one possibility, the downstream transmission member and / or the upstream transmission member comprises a stopper configured to block the blocking member in the closed position.

Ainsi, le moyen de rappel et la butée permettent à l'organe de blocage de s'auto-verrouiller en position de blocage et en position de fermeture.Thus, the return means and the stopper allow the blocking member to self-lock in the blocked position and in the closed position.

Selon une autre possibilité, l'organe de blocage est configuré pour se déplacer de la position de fermeture à la position d'ouverture par traction mécanique du système de secours mécanique. Par exemple, le système de secours mécanique peut être tracté manuellement.According to another possibility, the blocking member is configured to move from the closed position to the open position by mechanical traction of the mechanical emergency system. For example, the mechanical back-up system can be towed manually.

Selon une autre possibilité, la surface de came est configurée pour déplacer l'organe de blocage sous l'effet d'une poussée de l'organe de transmission amont entre la position de fermeture de l'organe de blocage et la position d'ouverture de l'organe de blocage. Le déplacement de l'organe de blocage de la position de fermeture à la position d'ouverture permet de ré-accoupler l'organe de blocage et l'organe de transmission amont.According to another possibility, the cam surface is configured to move the locking member under the effect of a thrust from the upstream transmission member between the closed position of the locking member and the open position. of the blocking member. The movement of the locking member from the closed position to the open position makes it possible to re-couple the locking member and the upstream transmission member.

Selon une possibilité, l'organe de transmission aval comprend une ouverture configurée pour recevoir au moins une partie de l'organe de transmission amont.According to one possibility, the downstream transmission member comprises an opening configured to receive at least part of the upstream transmission member.

Selon un mode de réalisation, la position de fermeture est définie par un positionnement relatif de l'organe de blocage par rapport à l'ouverture de l'organe de transmission aval. En particulier, la position de fermeture correspond à une position dans laquelle l'organe de blocage définit avec l'ouverture un emplacement de blocage de l'organe de transmission dont les dimensions correspondent à celle d'une partie de blocage de l'organe de transmission.According to one embodiment, the closed position is defined by a relative positioning of the locking member with respect to the opening of the downstream transmission member. In particular, the closed position corresponds to a position in which the locking member defines with the opening a locking location of the transmission member whose dimensions correspond to that of a locking part of the locking member. transmission.

Selon un mode de réalisation, la position d'ouverture est définie par un positionnement relatif de l'organe de blocage par rapport à l'ouverture.According to one embodiment, the open position is defined by a relative positioning of the locking member with respect to the opening.

Selon un mode de réalisation, le logement est configuré pour permettre son déplacement entre la position de blocage relatif et la position de déblocage relatif.According to one embodiment, the housing is configured to allow it to move between the relative locking position and the relative unlocking position.

Dans la description qui va suivre, il faut comprendre par les termes « amont » et « aval » la position des pièces composant l'agencement de transmission par rapport au sens du mouvement transmis par chacune de ces pièces. En particulier, « aval » signifie qui se rapproche de la serrure (32), « amont » se rapproche de l'actionneur électrique 24 de commande de verrouillage/déverrouillage.In the following description, the terms “upstream” and “downstream” should be understood to mean the position of the parts making up the transmission arrangement with respect to the direction of movement transmitted by each of these parts. In particular, “downstream” means which approaches the lock (32), “upstream” approaches the electric actuator 24 for locking / unlocking control.

La figure 1 montre une partie du mécanisme de verrouillage 1 d'une serrure 32 (représentée à la figure 10) et plus particulièrement un agencement de transmission 2 comprenant un organe de blocage 4, un organe de transmission amont 5 et un organe de transmission aval comprenant un support 3 et une partie de levier 6.The figure 1 shows part of the locking mechanism 1 of a lock 32 (shown in figure 10 ) and more particularly a transmission arrangement 2 comprising a locking member 4, an upstream transmission member 5 and a downstream transmission member comprising a support 3 and a lever part 6.

Le support 3, s'étendant selon un axe longitudinal XX, comprend une ouverture 7, par exemple un trou oblong, s'étendant selon un axe parallèle par rapport à l'axe longitudinal XX.The support 3, extending along a longitudinal axis XX, comprises an opening 7, for example an oblong hole, extending along an axis parallel to the longitudinal axis XX.

L'organe de transmission amont 5 destiné à être relié à un actionneur, par exemple une tringle ou un câble, se compose d'une première partie 11 s'étendant parallèlement à l'axe longitudinal XX et d'une deuxième partie (non visible) s'étendant transversalement par rapport à l'axe longitudinal XX de manière à s'insérer à travers l'ouverture 7 du support 3.The upstream transmission member 5 intended to be connected to an actuator, for example a rod or a cable, consists of a first part 11 extending parallel to the longitudinal axis XX and of a second part (not visible ) extending transversely to the longitudinal axis XX so as to fit through the opening 7 of the support 3.

L'organe de blocage 4, par exemple un crochet, est configuré pour être mobile en rotation, par rapport à un axe de rotation A, transversal à l'axe longitudinal XX, entre une position de blocage relatif, dans laquelle l'organe de blocage 4 coopère avec l'organe de transmission amont 5 comme illustrée sur cette figure, et une position de déblocage relatif dans laquelle l'organe de blocage 4 est mobile selon au moins un degré de liberté par rapport à l'organe de transmission amont 5.The locking member 4, for example a hook, is configured to be movable in rotation, with respect to an axis of rotation A, transverse to the longitudinal axis XX, between a relative locking position, in which the locking member locking 4 cooperates with the upstream transmission member 5 as illustrated in this figure, and a relative unlocking position in which the locking member 4 is movable according to at least one degree of freedom with respect to the upstream transmission member 5 .

Plus précisément, l'organe de blocage 4 comprend un logement 13 configuré pour recevoir la deuxième partie de l'organe de transmission amont 5, la position de blocage relatif correspondant à une solidarisation de l'organe de blocage 4 avec l'organe de transmission amont 5.More precisely, the locking member 4 comprises a housing 13 configured to receive the second part of the upstream transmission member 5, the locking position relative corresponding to a securing of the locking member 4 with the upstream transmission member 5.

Cette solidarisation se traduit par le contact entre l'organe de transmission amont 5 et une surface de contact 12 formée par le logement 13 de l'organe de blocage 4, la surface de contact 12 étant orientée perpendiculairement à un segment reliant l'axe de rotation A à la surface de contact 12, la surface de contact étant visible sur la figure 5A. L'organe de blocage 4 comprend également un orifice 16 configuré pour recevoir un système de secours mécanique 23 représenté aux figures 1 à 4, tel qu'un câble ou une tringle par exemple. Ainsi, lorsque le système de secours mécanique 23 est tracté mécaniquement l'organe de blocage 6 se déplace autour de l'axe de rotation A d'une position de fermeture, dans laquelle l'organe de blocage 4 s'oppose au passage de la position de blocage à la position de déblocage, comme illustrée aux figures 4 et 5A, à une position d'ouverture dans laquelle l'organe de transmission amont 5 peut passer de la position de blocage relatif à la position de déblocage relatif, comme représentée à la figure 5C par exemple.This joining results in the contact between the upstream transmission member 5 and a contact surface 12 formed by the housing 13 of the locking member 4, the contact surface 12 being oriented perpendicular to a segment connecting the axis of rotation A to the contact surface 12, the contact surface being visible on the figure 5A . The locking member 4 also comprises an orifice 16 configured to receive a mechanical emergency system 23 shown in figures 1 to 4 , such as a cable or a rod for example. Thus, when the mechanical emergency system 23 is mechanically towed, the blocking member 6 moves around the axis of rotation A from a closed position, in which the blocking member 4 opposes the passage of the locked position to the unlocked position, as shown in figures 4 and 5A , to an open position in which the upstream transmission member 5 can pass from the relative locking position to the relative unlocking position, as shown in figure 5C for example.

Selon un autre mode de réalisation, le système de secours mécanique 23 est intégré directement à l'organe de blocage 4. En d'autres termes, l'organe de blocage 4 et le système de secours mécanique ne forment qu'une seule pièce.According to another embodiment, the mechanical back-up system 23 is integrated directly into the locking member 4. In other words, the locking member 4 and the mechanical back-up system form a single part.

Plus précisément, l'orifice 16 est disposé dans le plan de la surface de contact 12 de l'organe de blocage 4.More precisely, the orifice 16 is disposed in the plane of the contact surface 12 of the locking member 4.

La traction mécanique peut être réalisée selon un mouvement sensiblement perpendiculaire par rapport au segment reliant l'axe de rotation A à la surface de contact 12 de l'organe de blocage 4.Mechanical traction can be achieved in a movement that is substantially perpendicular to the segment connecting the axis of rotation A to the contact surface 12 of the locking member 4.

Il est à noter que le mouvement susmentionné n'est pas limitatif de l'invention.It should be noted that the aforementioned movement is not limiting of the invention.

Le support 3 comprend une butée 17 s'étendant transversalement vers l'extérieur par rapport à l'axe longitudinal XX.The support 3 comprises a stop 17 extending transversely outwardly with respect to the longitudinal axis XX.

Cette butée 17 est configurée pour bloquer en rotation l'organe de blocage 4 dans sa position de fermeture lorsque l'organe de blocage 4 est mobile de sa position d'ouverture à sa position de fermeture.This stopper 17 is configured to block the blocking member 4 in rotation in its closed position when the blocking member 4 is movable from its open position to its closed position.

Le support 3 comprend également un moyen de rappel 18, par exemple une languette, telle qu'illustrée sur cette figure, ou un ressort.The support 3 also comprises a return means 18, for example a tongue, as illustrated in this figure, or a spring.

Le moyen de rappel 18 est configuré pour bloquer la rotation de l'organe de blocage 4 de sa position de fermeture à sa position d'ouverture par le rappel de l'organe de blocage 4 vers sa position de fermeture, telle qu'illustrée aux figures 4 et 5A par exemple.The return means 18 is configured to block the rotation of the blocking member 4 from its closed position to its open position by the return of the blocking member 4 to its closed position, as illustrated in figures 4 and 5A for example.

En d'autres termes, la position de fermeture est définie par un positionnement relatif de l'organe de blocage 4 par rapport à l'ouverture 7 du support 3.In other words, the closed position is defined by a relative positioning of the locking member 4 with respect to the opening 7 of the support 3.

En particulier, la position de fermeture de l'organe de blocage 4 correspond à une position dans laquelle l'organe de blocage 4 définit avec l'ouverture 7 un emplacement de blocage de l'organe de transmission amont 5 dont les dimensions correspondent à celle d'une partie de blocage de l'organe de transmission amont 5.In particular, the closed position of the locking member 4 corresponds to a position in which the locking member 4 defines with the opening 7 a locking location of the upstream transmission member 5, the dimensions of which correspond to that a blocking part of the upstream transmission member 5.

En effet, la deuxième partie de l'organe de transmission amont 5 est dimensionnée de manière à ce que cette deuxième partie de l'organe de transmission amont 5 puisse s'insérer dans le logement 13 de l'organe de blocage 4, comme représentées aux figures 1 et 5E par exemple.Indeed, the second part of the upstream transmission member 5 is dimensioned so that this second part of the upstream transmission member 5 can be inserted into the housing 13 of the locking member 4, as shown. to figures 1 and 5E for example.

De plus, le logement 13 de l'organe de blocage 4 est disposé en regard de l'ouverture 7 du support 3, en position de fermeture.In addition, the housing 13 of the locking member 4 is arranged opposite the opening 7 of the support 3, in the closed position.

La position d'ouverture, quant à elle, est définie également par un positionnement relatif de l'organe de blocage 4 par rapport à l'ouverture 7 du support 3.The open position, for its part, is also defined by a relative positioning of the locking member 4 with respect to the opening 7 of the support 3.

En effet, lorsque l'organe de blocage 4 est en position d'ouverture, le logement 13 n'est plus en regard de l'ouverture 7 du support 3.Indeed, when the locking member 4 is in the open position, the housing 13 is no longer facing the opening 7 of the support 3.

Le logement 13 est donc configuré pour permettre son déplacement entre la position de blocage relatif et la position de déblocage relatif.The housing 13 is therefore configured to allow it to move between the relative locking position and the relative unlocking position.

La partie de levier 6 est mobile en rotation par rapport au support 3 selon un axe de rotation B.The lever part 6 is rotatable relative to the support 3 along an axis of rotation B.

L'axe de rotation B de la partie de levier 6 se situe sur un même plan que l'axe de rotation A de l'organe de blocage 4.The axis of rotation B of the lever part 6 is located on the same plane as the axis of rotation A of the locking member 4.

II est à noter que l'organe de blocage 4 est disposé sur une première face 21 du support 3 et que la partie de levier 6 est disposée sur une deuxième face du support 3, opposée à la première face 21.It should be noted that the locking member 4 is disposed on a first face 21 of the support 3 and that the lever part 6 is disposed on a second face of the support 3, opposite to the first face 21.

Les figures 1 et 2 montrent le mécanisme de verrouillage 1 comprenant l'agencement de transmission 2 dans lequel l'organe de blocage 4 est en position de blocage relatif.The figures 1 and 2 show the locking mechanism 1 comprising the transmission arrangement 2 in which the locking member 4 is in the relative locking position.

La partie de levier 6 est en contact avec le pêne 22.The lever part 6 is in contact with the bolt 22.

Ceci se traduit par l'actionnement de l'actionneur 24 (illustré à la figure 10) exerçant une force de tirage sur l'organe de transmission amont 5.This results in the actuation of the actuator 24 (illustrated in figure 10 ) exerting a pulling force on the upstream transmission member 5.

La figure 3 montre le mécanisme de verrouillage 1 dans lequel le système de secours mécanique 23 a été actionné.The figure 3 shows the locking mechanism 1 in which the mechanical emergency system 23 has been activated.

En effet, ceci se traduit par le passage de l'organe de blocage 4 de la position de blocage relatif, tel que représenté aux figures 1 et 2 à la position de déblocage relatif.Indeed, this results in the passage of the locking member 4 from the relative locking position, as shown in figures 1 and 2 to the relative unlocking position.

Le moyen de rappel 18 est donc compressé par l'organe de blocage 4 sous l'effet de la force de traction exercée.The return means 18 is therefore compressed by the locking member 4 under the effect of the tensile force exerted.

L'organe de blocage 4 et l'organe de transmission amont 5 ne coopèrent donc plus.The locking member 4 and the upstream transmission member 5 therefore no longer cooperate.

La figure 4 montre le mécanisme de verrouillage 1 lorsque l'organe de blocage 4 est en position de fermeture.The figure 4 shows the locking mechanism 1 when the locking member 4 is in the closed position.

En effet, une fois la position de déblocage relatif de l'organe de blocage 4 obtenue, l'organe de transmission amont 5 ne se trouve plus dans le logement 13 de l'organe de blocage 4 et peut être mobile dans l'ouverture 7 du support 3.Indeed, once the relative unlocking position of the locking member 4 has been obtained, the upstream transmission member 5 is no longer located in the housing 13 of the locking member 4 and can be movable in the opening 7. support 3.

Une fois le système de secours mécanique 23 relâché, l'organe de blocage 4 se trouve en position de fermeture telle qu'illustrée sur cette figure, notamment par la force de rappel exercée par le moyen de rappel 18.Once the mechanical emergency system 23 has been released, the locking member 4 is in the closed position as illustrated in this figure, in particular by the return force exerted by the return means 18.

Les figures 5A à 5E montrent différentes étapes permettant un réarmement du mécanisme de verrouillage lorsque le système de secours mécanique 23 a été utilisé, par exemple en cas de défaillance électrique du mécanisme de verrouillage 1 de l'ouvrant d'un véhicule automobile.The figures 5A to 5E show different steps allowing rearming of the locking mechanism when the mechanical emergency system 23 has been used, for example in the event of an electrical failure of the locking mechanism 1 of the opening of a motor vehicle.

Le réarmement se réalise par le passage de l'organe de blocage 4 de sa position de fermeture à sa position d'ouverture pour enfin se retrouver en position de blocage relatif.The rearming is carried out by the passage of the blocking member 4 from its closed position to its open position to finally find itself in the relative blocking position.

L'organe de blocage 4 comprend une surface de came 31 configurée pour déplacer l'organe de blocage 4, sous l'effet d'une poussée de l'organe de transmission amont 5, de façon à positionner l'organe de transmission amont 5 et l'organe de blocage 4 dans la position de blocage relatif, comme représenté dans à la figure 5E.The locking member 4 comprises a cam surface 31 configured to move the locking member 4, under the effect of a thrust from the upstream transmission member 5, so as to position the upstream transmission member 5 and the locking member 4 in the relative locking position, as shown in figure 5E .

Sur la figure 5A, l'organe de transmission amont 5 ne coopère plus avec l'organe de blocage 4. En effet, le système de secours mécanique 23 a été exécuté. Ceci se traduit par une position de fermeture de l'organe de blocage 4, par le moyen de rappel 18 et la butée 17.On the figure 5A , the upstream transmission member 5 no longer cooperates with the locking member 4. In fact, the mechanical emergency system 23 has been executed. This results in a closed position of the locking member 4, by the return means 18 and the stop 17.

Sur la figure 5B l'organe de transmission amont 5 entre en contact avec la surface de came 31 de l'organe de blocage 4.On the figure 5B the upstream transmission member 5 comes into contact with the cam surface 31 of the locking member 4.

Plus précisément, c'est la deuxième partie de l'organe de transmission amont 5, qui, à travers le déplacement dans l'ouverture 7 du support 3, va entrer en contact avec la surface de came 31 de l'organe de blocage 4.More precisely, it is the second part of the upstream transmission member 5, which, through the movement in the opening 7 of the support 3, will come into contact with the cam surface 31 of the locking member 4 .

Sur la figure 5C, l'organe de transmission amont 5 longe la surface de came 31 de l'organe de blocage 4, permettant à l'organe de blocage 4 de passer de sa position de fermeture à sa positon d'ouverture.On the figure 5C , the upstream transmission member 5 runs along the cam surface 31 of the locking member 4, allowing the locking member 4 to go from its closed position to its open position.

Dans cette position, le moyen de rappel 18 est comprimé par l'organe de blocage 4.In this position, the return means 18 is compressed by the locking member 4.

Sur la figure 5D, l'organe de transmission amont 5 est en contact avec la surface de contact 12 de l'organe de blocage 4.On the figure 5D , the upstream transmission member 5 is in contact with the contact surface 12 of the locking member 4.

Sur la figure 5E, l'organe de blocage 4 et l'organe de transmission amont 5 sont solidaires entre eux et donc coopère entre eux. En effet, l'organe de blocage 4 et l'organe de translation amont sont dans la position de blocage relatif.On the figure 5E , the locking member 4 and the upstream transmission member 5 are integral with each other and therefore cooperate with each other. Indeed, the locking member 4 and the upstream translation member are in the relative locking position.

Dans les paragraphes suivants, le fonctionnement de l'invention selon le premier mode de réalisation est détaillé.In the following paragraphs, the operation of the invention according to the first embodiment is detailed.

Lors du verrouillage électrique d'un ouvrant de véhicule automobile, par exemple d'un coffre de véhicule automobile, un utilisateur peut commander électriquement, et à distance, ce verrouillage électrique.During the electric locking of a motor vehicle opening, for example of a motor vehicle trunk, a user can electrically control, and remotely, this electric locking.

Lorsque le verrouillage électrique de l'ouvrant se déroule correctement, un actionneur 24 (illustré à la figure 10) tel qu'un moteur électrique, va exercer une force de traction sur l'organe de transmission amont 5, selon un mouvement translatoire et selon l'axe longitudinal XX d'extension du support 3.When the electrical locking of the sash is performed correctly, an actuator 24 (shown in figure 10 ) such as an electric motor, will exert a tensile force on the upstream transmission member 5, according to a translatory movement and along the longitudinal axis XX of extension of the support 3.

L'organe de transmission amont 5 est solidaire de l'organe de blocage 4, se traduisant par le contact de l'organe de transmission amont 5 avec la surface de contact 12 de l'organe de blocage 4.The upstream transmission member 5 is integral with the locking member 4, resulting in the contact of the upstream transmission member 5 with the contact surface 12 of the locking member 4.

L'organe de blocage 4 comprend donc une surface de contact 12 configurée pour entrer en contact avec l'organe de transmission amont 5 et/ou de l'organe de transmission aval 6, l'organe de blocage 4 étant guidé entre la position de fermeture et la position d'ouverture selon une trajectoire comprise dans le plan de la surface de contact 12.The locking member 4 therefore comprises a contact surface 12 configured to come into contact with the upstream transmission member 5 and / or the downstream transmission member 6, the locking member 4 being guided between the position of closure and the open position along a path included in the plane of the contact surface 12.

Plus précisément, l'organe de blocage 4 est mobile en rotation autour d'un axe de rotation A, la surface de contact 12 étant orientée perpendiculairement à un segment reliant l'axe de rotation A à ladite surface 12.More precisely, the locking member 4 is movable in rotation about an axis of rotation A, the contact surface 12 being oriented perpendicularly to a segment connecting the axis of rotation A to said surface 12.

L'organe de transmission amont 5 est donc configuré pour déplacer le support 3 par le biais de l'actionneur électrique 24, lorsque l'organe de blocage 4 est en position de blocage relatif, l'organe de transmission amont 5 traversant l'ouverture 7 du support 3 La partie de levier 6 sera donc entrainé en rotation selon l'axe de rotation B, par le déplacement du support 3, agissant ainsi sur la serrure de l'ouvrant 32, et plus particulièrement sur le pêne 22 de la serrure 32 afin de verrouiller l'ouvrant.The upstream transmission member 5 is therefore configured to move the support 3 by means of the electric actuator 24, when the blocking member 4 is in the relative blocking position, the upstream transmission member 5 passing through the opening. 7 of the support 3 The lever part 6 will therefore be rotated along the axis of rotation B, by the displacement of the support 3, thus acting on the lock of the leaf 32, and more particularly on the bolt 22 of the lock 32 in order to lock the sash.

En effet, la partie de levier 6 est relié au support 3 par l'intermédiaire d'une liaison pivot, confondue avec l'axe de rotation A de l'organe de blocage 4, au niveau de la deuxième face du support 3.Indeed, the lever part 6 is connected to the support 3 by means of a pivot connection, coincident with the axis of rotation A of the locking member 4, at the level of the second face of the support 3.

Dans le cas d'une quelconque défaillance électrique de l'ouvrant ou du véhicule, l'agencement de transmission 2 tel que représenté sur la figure 1 est bloqué dans cette position par exemple, c'est-à-dire dans la position de blocage relatif, et la position de verrouillage de l'ouvrant ne peut donc pas être atteinte.In the event of any electrical failure of the opening or of the vehicle, the transmission arrangement 2 as shown in figure figure 1 is locked in this position for example, that is to say in the relative locking position, and the locking position of the opening can therefore not be reached.

L'utilisateur peut donc croire que l'ouvrant de son véhicule est verrouillé alors que ce n'est pas le cas.The user can therefore believe that the door of his vehicle is locked when this is not the case.

Afin de débloquer le mécanisme de verrouillage 1 de son ouvrant, l'utilisateur exerce une force de traction sur le système de secours mécanique 23 entraînant ainsi le désaccouplement de l'organe de transmission amont 5 et l'organe de blocage 4 par la rotation de l'organe de blocage 4selon l'axe de rotation A.In order to unlock the locking mechanism 1 of its opening, the user exerts a traction force on the mechanical emergency system 23 thus causing the disconnection of the upstream transmission member 5 and the locking member 4 by the rotation of the locking member 4 according to the axis of rotation A.

En d'autres mots, l'organe de blocage 4 se déplace de sa position de fermeture à sa position d'ouverture, permettant à l'organe de transmission amont 5 de ne plus être enfermé dans le logement 13 de l'organe de blocage 4.In other words, the locking member 4 moves from its closed position to its open position, allowing the upstream transmission member 5 to no longer be locked in the housing 13 of the locking member. 4.

Une fois le désaccouplement effectué, l'organe de transmission amont 5 pourra se déplacer librement à travers l'ouverture 7 du support 3.Once the disconnection has been carried out, the upstream transmission member 5 will be able to move freely through the opening 7 of the support 3.

Le moyen de rappel 18 entraînera l'organe de blocage 4 dans sa position de fermeture, c'est à dire sans que l'organe de transmission amont 5 et l'organe de blocage 4 soient solidaires entre eux, tel que représenté sur les figures 4, 5A. Afin de réarmer le mécanisme de verrouillage 1 l'utilisateur déplace l'organe de transmission amont 5 jusqu'à entrer en contact avec la surface de came 31 de l'organe de blocage 4.The return means 18 will drive the locking member 4 into its closed position, that is to say without the upstream transmission member 5 and the locking member 4 being integral with each other, as shown in the figures. figures 4 , 5A . In order to reset the locking mechanism 1, the user moves the upstream transmission member 5 until it comes into contact with the cam surface 31 of the locking member 4.

En effet, la surface de came 31 de l'organe de blocage 4 se situe sur le passage de l'ouverture 7 du support 3, lorsque l'organe de blocage 4 est en position de fermeture, comme représentée sur les figures 4 et 5A, de manière à ce que lorsque l'organe de transmission amont 5 se déplace à travers l'ouverture 7 du support 3, et lorsque celui-ci rencontre l'organe de blocage 4, et plus particulièrement la surface de came 31 de l'organe de blocage 4, l'organe de blocage 4 passe de sa position de fermeture à sa position d'ouverture, comme illustrées aux figures 5B et 5C.Indeed, the cam surface 31 of the locking member 4 is located on the passage of the opening 7 of the support 3, when the locking member 4 is in the closed position, as shown in the figures. figures 4 and 5A , so that when the upstream transmission member 5 moves through the opening 7 of the support 3, and when the latter meets the locking member 4, and more particularly the cam surface 31 of the locking member 4, the locking member 4 goes from its closed position to its open position, as illustrated in figures 5B and 5C .

Une poussée de l'organe de transmission amont 5 sur la surface de came 31 de l'organe de blocage 4 permet donc de repositionner l'organe de transmission amont 5 et l'organe de blocage 4 dans la position de blocage relatif telle que représentée sur la figure 5E.A thrust of the upstream transmission member 5 on the cam surface 31 of the locking member 4 therefore makes it possible to reposition the upstream transmission member 5 and the locking member 4 in the relative locking position as shown. on the figure 5E .

Plus précisément, l'organe de blocage 4, par le moyen de rappel 18, reviendra à sa position de blocage relatif.More precisely, the blocking member 4, by the return means 18, will return to its relative blocking position.

Le moyen de rappel 18 et la butée 17 sont des moyens auto-verrouillant de l'organe de blocage 4 dans sa position de fermeture et dans sa position de blocage relatif.The return means 18 and the stop 17 are self-locking means of the blocking member 4 in its closed position and in its relative blocking position.

Une fois ces étapes réalisées et la défaillance électrique solutionnée, le verrouillage électrique de la serrure 32 peut être réalisé électriquement.Once these steps have been carried out and the electrical failure resolved, the electrical locking of the lock 32 can be carried out electrically.

La figure 6 montre le mécanisme de verrouillage 1' selon un deuxième mode de réalisation de l'invention.The figure 6 shows the locking mechanism 1 'according to a second embodiment of the invention.

Le mécanisme de verrouillage comprend une serrure 32 de verrouillage 1' de l'ouvrant comprenant un cliquet 25 et un pêne 22' configuré pour coopérer de façon à permettre le verrouillage ou le déverrouillage de l'ouvrant.The locking mechanism comprises a lock 32 for locking 1 'of the opening comprising a pawl 25 and a bolt 22' configured to cooperate so as to allow the locking or unlocking of the opening.

Le mécanisme de verrouillage comprend un actionneur électrique 24 et un agencement de transmission 2' configuré pour transmettre un mouvement de l'actionneur électrique 24 au pêne 22' en vue du déplacement du pêne 22' de la serrure 32 entre une position de déverrouillage dans laquelle le pêne 22' est libéré du cliquet et une position de verrouillage dans laquelle le pêne 22' est bloqué par le cliquet.The locking mechanism includes an electric actuator 24 and a transmission arrangement 2 'configured to transmit movement of the electric actuator 24 to the bolt 22' for movement of the bolt 22 'of the lock 32 between an unlock position in which the bolt 22 'is released from the pawl and a locking position in which the bolt 22' is blocked by the pawl.

Comme cela est visible sur la figure 10, l'actionneur électrique 24 comprend un arbre de sortie entrainé en rotation et muni d'une vis sans fin 26.As can be seen on the figure 10 , the electric actuator 24 comprises an output shaft driven in rotation and provided with a worm 26.

L'agencement de transmission 2' comprend un organe de transmission amont 5'. L'organe de transmission amont 5' est réalisé dans ce mode de réalisation sous forme d'une roue dentée montée mobile en rotation autour d'un axe C qui coopère avec la vis sans fin 26. Ainsi la vis sans fin 26 peut entraîner en rotation l'organe de transmission amont 5' autour de l'axe C.The transmission arrangement 2 'comprises an upstream transmission member 5'. The upstream transmission member 5 ′ is produced in this embodiment in the form of a toothed wheel mounted to be movable in rotation about an axis C which cooperates with the worm 26. Thus the worm 26 can drive in rotation of the upstream transmission member 5 'around axis C.

L'agencement de transmission 2' comprend un organe de transmission aval 6' réalisé dans ce mode de réalisation sous forme d'un levier monté mobile en rotation.The transmission arrangement 2 ′ comprises a downstream transmission member 6 ′ produced in this embodiment in the form of a lever mounted to be movable in rotation.

En particulier, l'organe de transmission aval 6' peut être monté mobile en rotation autour du même axe C de rotation de l'organe de transmission amont 5'.In particular, the downstream transmission member 6 'can be mounted to be able to rotate about the same axis C of rotation of the upstream transmission member 5'.

L'organe de transmission aval 6' comprend une première butée 27 d'entrainement du pêne 22'. L'organe de transmission aval 6' comprend également une deuxième butée de blocage 17', ainsi qu'une surface de came 28 disposée de façon adjacente à la deuxième butée de blocage 17'.The downstream transmission member 6 'comprises a first stop 27 for driving the bolt 22'. The downstream transmission member 6 'also comprises a second blocking stop 17', as well as a cam surface 28 disposed adjacent to the second blocking stop 17 '.

L'organe de transmission amont 5' est configuré pour transmettre un mouvement de l'actionneur 24 à l'organe de transmission aval 6' et l'organe de transmission aval 6' est configuré pour transmettre un mouvement au pêne 22'.The upstream transmission member 5 'is configured to transmit a movement from the actuator 24 to the downstream transmission member 6' and the downstream transmission member 6 'is configured to transmit a movement to the bolt 22'.

L'agencement de transmission 2' comprend un organe de blocage 4' monté mobile en rotation autour d'un axe de rotation C par rapport à l'organe de transmission amont 5'. En particulier, l'axe de rotation C est parallèle à l'axe de rotation de l'organe de transmission aval 6' et positionné de façon décalée. L'organe de blocage 4' comprend une partie d'extension 29 destinée à venir en butée contre la deuxième butée de blocage 17' de l'organe de transmission aval 6'.The transmission arrangement 2 ′ comprises a locking member 4 ′ mounted so as to be able to rotate about an axis of rotation C relative to the upstream transmission member 5 ′. In particular, the axis of rotation C is parallel to the axis of rotation of the downstream transmission member 6 'and positioned in an offset manner. The locking member 4 'comprises an extension part 29 intended to come into abutment against the second locking stop 17' of the downstream transmission member 6 '.

L'organe de blocage 4' est configuré pour définir avec l'organe de transmission aval 6' :

  • une position de blocage relatif dans laquelle l'organe de blocage 4' coopère avec l'organe de transmission aval 6' de manière à permettre la transmission d'un mouvement entre l'organe de transmission amont 5' et l'organe de transmission aval 6', et
  • une position de déblocage relatif dans laquelle l'organe de blocage 4' est mobile selon au moins un degré de liberté par rapport à l'organe de transmission amont 5'.
The blocking member 4 'is configured to define with the downstream transmission member 6':
  • a relative blocking position in which the blocking member 4 'cooperates with the downstream transmission member 6' so as to allow the transmission of a movement between the upstream transmission member 5 'and the downstream transmission member 6', and
  • a relative unlocking position in which the locking member 4 'is movable according to at least one degree of freedom with respect to the upstream transmission member 5'.

Dans ce mode de réalisation, dans la position de déblocage relatif, la rotation autour de l'axe C de rotation de l'organe de transmission aval 6' par rapport à l'organe de transmission amont 5' est permise, assurant ainsi un degré de liberté supplémentaire par rapport à la position de blocage relatif.In this embodiment, in the relative unlocking position, the rotation around the axis C of rotation of the downstream transmission member 6 'with respect to the upstream transmission member 5' is allowed, thus ensuring a degree additional freedom compared to the relative blocking position.

En particulier, dans la position de blocage relatif, la partie d'extension 29 de l'organe de blocage 4' coopère avec la deuxième butée de blocage 17' de l'organe de transmission aval 6'.In particular, in the relative blocking position, the extension part 29 of the blocking member 4 'cooperates with the second blocking stop 17' of the downstream transmission member 6 '.

En position de blocage relatif, l'organe de transmission amont 5' et l'organe de transmission aval 6' sont solidaires en mouvement, grâce à la liaison mécanique réalisée par l'organe de blocage 4'. La première butée d'entraînement 27 de l'organe de transmission aval 6'peut entraîner le pêne 22' dans une position de verrouillage visible sur la figure 7.In the relative blocking position, the upstream transmission member 5 'and the downstream transmission member 6' are integral in movement, thanks to the mechanical connection produced by the locking member 4 '. The first drive stop 27 of the downstream transmission member 6 ′ can drive the bolt 22 ′ into a locking position visible on the figure 7 .

Dans la position de déblocage relatif, la partie d'extension 29 de l'organe de blocage 4' est en contact avec la surface de came 28 et glisse sur cette surface de came 28.In the relative release position, the extension part 29 of the locking member 4 'is in contact with the cam surface 28 and slides on this cam surface 28.

L'organe de blocage 4' est relié à un système de secours mécanique 23' étant configuré pour déclencher un mouvement de l'organe de blocage 4' d'une position de fermeture, dans laquelle l'organe de blocage 4' s'oppose au passage de la position de blocage à la position de déblocage, comme illustrée à la figure 9, et une position d'ouverture dans laquelle l'organe de transmission amont 5' peut passer de la position de blocage relatif à la position de déblocage relatif, comme représenté à la figure 7.The locking member 4 'is connected to a mechanical emergency system 23' being configured to trigger a movement of the locking member 4 'from a closed position, in which the locking member 4' opposes when changing from the locked position to the unlocked position, as shown in figure 9 , and an open position in which the upstream transmission member 5 'can pass from the relative locking position to the relative unlocking position, as shown in figure 7 .

En particulier, l'organe de blocage 4' est relié au système de secours mécanique 23', comportant par exemple une tringle ou un câble, par l'intermédiaire d'un pivot 30 disposé de façon décalée par rapport à l'axe de rotation. Ainsi, une traction sur le système de secours mécanique 23' permet d'entrainer en rotation l'organe de blocage 4' autour de l'axe et de libérer ainsi le mouvement de rotation de l'organe de transmission aval 6' par rapport à l'organe de transmission amont 5'.In particular, the locking member 4 ′ is connected to the mechanical emergency system 23 ′, comprising for example a rod or a cable, by means of a pivot 30 disposed in an offset manner with respect to the axis of rotation. . Thus, traction on the mechanical emergency system 23 'allows the locking member 4' to be rotated around the axis and thus to release the rotational movement of the downstream transmission member 6 'with respect to the upstream transmission member 5 '.

La traction mécanique peut être réalisée selon un mouvement sensiblement perpendiculaire par rapport à l'axe de rotation C de l'organe de transmission amont 5'. Dans cette position, l'organe de transmission aval 6' qui est libre en rotation ne contraint plus le pêne 22' ce qui permet de déverrouiller l'ouvrant.Mechanical traction can be achieved in a movement that is substantially perpendicular to the axis of rotation C of the upstream transmission member 5 '. In this position, the downstream transmission member 6 'which is free to rotate no longer constrains the bolt 22' which enables the opening to be unlocked.

Selon une possibilité, un organe de rappel (non représenté) peut être associé à l'organe de blocage 4', par exemple un ressort.According to one possibility, a return member (not shown) can be associated with the locking member 4 ', for example a spring.

L'organe de rappel est situé sur l'axe de rotation de l'organe de blocage 4'.The return member is located on the axis of rotation of the locking member 4 '.

Selon un autre mode de réalisation, l'organe de rappel est situé sur l'axe de rotation de l'organe de transmission aval 6'. Dans ce cas l'organe de rappel est déporté par rapport à l'organe de blocage 4'.According to another embodiment, the return member is located on the axis of rotation of the downstream transmission member 6 '. In this case, the return member is offset relative to the locking member 4 '.

L'organe de rappel étant configurer pour ramener l'organe de blocage 4' vers sa position de fermeture.The return member being configured to return the locking member 4 'to its closed position.

Selon une possibilité, l'organe de transmission aval 6' peut comprendre également un organe de rappel (non représenté), par exemple un ressort.According to one possibility, the downstream transmission member 6 'may also include a return member (not shown), for example a spring.

L'organe de blocage est situé sur l'axe de rotation de l'organe de transmission aval 6'.The locking member is located on the axis of rotation of the downstream transmission member 6 '.

Ce ressort permet de ramener l'organe de transmission aval 6' vers la position de blocage relatif avec l'organe de blocage 4'.This spring enables the downstream transmission member 6 'to be brought back to the relative blocking position with the blocking member 4'.

Dans les paragraphes suivants, le fonctionnement de l'invention selon le second mode de réalisation est détaillé.In the following paragraphs, the operation of the invention according to the second embodiment is detailed.

Dans un mode de fonctionnement normal du verrouillage électrique d'un ouvrant de véhicule automobile, par exemple d'un coffre de véhicule automobile, un utilisateur peut commander électriquement et à distance le verrouillage électrique par l'intermédiaire de l'actionneur électrique 24, illustré à la figure 10.In a normal operating mode of the electric locking of a motor vehicle opening, for example of a motor vehicle trunk, a user can electrically and remotely control the electric locking by means of the electric actuator 24, illustrated to the figure 10 .

L'arbre de sortie de l'actionneur 24 entraîne l'organe de transmission amont 5' en rotation autour de l'axe C. L'organe de transmission amont 5' entraîne l'organe de transmission aval 6' autour de l'axe C, l'organe de blocage 4' assurant la solidarisation en mouvement de l'organe de transmission amont 5' et de l'organe de transmission aval 6'.The output shaft of the actuator 24 drives the upstream transmission member 5 'in rotation about the axis C. The upstream transmission member 5' drives the downstream transmission member 6 'around the axis C, the locking member 4 'ensuring the joining in movement of the upstream transmission member 5' and of the downstream transmission member 6 '.

L'organe de transmission aval 6' coopère avec le pêne 22' pour le déplacer vers sa position de fermeture, comme cela est visible sur la figure 6 ou pour permettre son ouverture comme cela est visible sur la figure 7.The downstream transmission member 6 'cooperates with the bolt 22' to move it towards its closed position, as can be seen on the figure. figure 6 or to allow its opening as can be seen on the figure 7 .

Dans le cas d'une défaillance électrique de l'actionneur 24 ou de la commande de l'actionneur 24, l'agencement de transmission 2' peut être bloquée.In the event of an electrical failure of the actuator 24 or of the control of the actuator 24, the transmission arrangement 2 'may be blocked.

Afin de débloquer le mécanisme de verrouillage 1' de l'ouvrant, l'utilisateur exerce directement ou indirectement une force de traction sur le système de secours mécanique 23' entraînant ainsi le désaccouplement de l'organe de transmission amont 5 et l'organe de blocage 4 par la rotation de l'organe de blocage 4 selon l'axe de rotation parallèle à l'axe de rotation C de l'organe de transmission amont 5', comme cela est visible sur la figure 8.In order to unlock the locking mechanism 1 ′ of the opening, the user directly or indirectly exerts a traction force on the mechanical emergency system 23 ′ thus causing the disconnection of the upstream transmission member 5 and the control member. blocking 4 by the rotation of the blocking member 4 along the axis of rotation parallel to the axis of rotation C of the upstream transmission member 5 ', as can be seen on the figure figure 8 .

En d'autres termes, l'organe de blocage 4' se déplace de sa position de fermeture à sa position d'ouverture, permettant à l'organe de transmission aval 6' d'être libre en rotation par rapport à l'organe de transmission amont 5'. Le pêne 22' est alors libéré et la serrure 32 de l'ouvrant peut être ouverte.In other words, the blocking member 4 'moves from its closed position to its open position, allowing the downstream transmission member 6' to be free in rotation relative to the upstream transmission member 5 '. The bolt 22 'is then released and the lock 32 of the opening can be opened.

Afin de réarmer le mécanisme de verrouillage 1', une fois que la défaillance de l'actionneur 24 ou de la commande de l'actionneur 24 est résolu, il suffit d'entraîner en rotation l'organe de transmission amont 5' dans un sens de déverrouillage de façon à supprimer le contact entre le pêne 22' et l'organe de transmission aval 6'.In order to reset the locking mechanism 1 ', once the failure of the actuator 24 or of the actuator control 24 is resolved, it suffices to rotate the upstream transmission member 5' in one direction. unlocking so as to eliminate the contact between the bolt 22 'and the downstream transmission member 6'.

L'organe de transmission aval 6'est alors ramené en rotation vers la position de blocage relatif grâce à l'organe de rappel. Dans le même temps, la partie d'extension 29 de l'organe de blocage 4' est en appui, sous l'effet de l'organe de rappel contre la surface de came 28, jusqu'à dépasser la butée de blocage 17'.The downstream transmission member 6 ′ then rotates back to the relative blocking position by virtue of the return member. At the same time, the extension part 29 of the locking member 4 'bears, under the effect of the return member against the cam surface 28, until it exceeds the locking stop 17'. .

Une fois passée la butée blocage 17', l'organe de blocage 4' est rabattu par l'organe de rappel en position de fermeture ce qui correspond à la position de blocage relatif avec l'organe de transmission aval 6', comme représenté à la figure 9.Once past the blocking stop 17 ', the blocking member 4' is folded by the return member into the closed position which corresponds to the relative blocking position with the downstream transmission member 6 ', as shown in the figure 9 .

Une fois ces étapes réalisées, le verrouillage électrique de la serrure 32, peut être réalisé à nouveau électriquement.Once these steps have been carried out, the electric locking of the lock 32 can be carried out again electrically.

Les avantages conférés par l'invention sont les suivants :
Le système de secours mécanique 23, 23' permet de sécuriser le verrouillage/déverrouillage de l'ouvrant de son véhicule mécaniquement lorsqu'une défaillance électrique touche le véhicule automobile.
The advantages conferred by the invention are as follows:
The mechanical emergency system 23, 23 'makes it possible to secure the locking / unlocking of the opening of the vehicle mechanically when an electrical fault affects the motor vehicle.

La solution permet donc de libérer le pêne 22, 22' de l'agencement de transmission 2, 2' et s'attache à réduire les efforts nécessaires à désaccoupler l'organe de transmission amont 5, 5' et l'organe de blocage 4, 4'.The solution therefore makes it possible to release the bolt 22, 22 'from the transmission arrangement 2, 2' and endeavors to reduce the forces required to disconnect the upstream transmission member 5, 5 'and the locking member 4. , 4 '.

Enfin, cette solution cherche à réarmer l'agencement de transmission 2, 2' lorsque le mécanisme de verrouillage 1, 1' devient à nouveau fonctionnel.Finally, this solution seeks to reset the transmission arrangement 2, 2 'when the locking mechanism 1, 1' becomes functional again.

Grâce à cette conception, l'activation du système de secours mécanique 23 ne nécessite que l'effort de friction pour libérer la fonction de l'agencement de transmission 1. En effet, l'effort de traction électrique de l'actionneur 24 devient un effort de traction mécanique de l'organe de blocage 4, par l'intermédiaire de la friction au niveau de la surface de contact 12.Thanks to this design, the activation of the mechanical emergency system 23 only requires the frictional force to release the function of the transmission arrangement 1. Indeed, the electric tractive force of the actuator 24 becomes a mechanical tensile force of the locking member 4, via the friction at the level of the contact surface 12.

Il est à noter qu'il est également possible que la fonction du système de secours mécanique de verrouillage soit commune avec la fonction de secours mécanique de déverrouillage, agissant dans ce cas sur le cliquet 25 de la serrure 32, permettant en une seule commande de débloquer les deux chaines cinématiques de verrouillage et de déverrouillage de l'ouvrant.It should be noted that it is also possible for the function of the mechanical emergency locking system to be common with the mechanical emergency unlocking function, in this case acting on the pawl 25 of the lock 32, allowing in a single command to unlock the two kinematic chains for locking and unlocking the opening.
