On a représenté sur les figures 1a et 1b respectivement une première et une deuxième vue de côté d'une serrure 1 motorisée pour véhicule automobile, par exemple pour un toit ouvrant d'un véhicule ou encore tout autre ouvrant de véhicule tel qu'une portière ou un coffre.We have shown on Figures 1a and 1b respectively a first and a second side view of a motorized lock 1 for a motor vehicle, for example for a sunroof of a vehicle or any other opening of a vehicle such as a door or a trunk.

Cette serrure 1 comporte :

  • un support 3 de serrure, formant sensiblement un boîtier, dont une vue de côté est mieux visible sur la figure 2,
  • un moteur 5, et
  • un mécanisme de verrouillage/déverrouillage 7.
This lock 1 comprises:
  • a support 3 of lock, substantially forming a housing, a side view is better visible on the figure 2 ,
  • a motor 5, and
  • a locking / unlocking mechanism 7.

En se référant aux figures 3 et 4, le mécanisme de verrouillage/déverrouillage 7 comporte :

  • un pêne 9 destiné à coopérer avec une gâche (non représentée),
  • un cliquet 11 de retenue du pêne 9 (figure 4),
  • un pion d'ouverture 13 (figure 4) porté par le cliquet 11,
  • un coulisseau 15 (mieux visible sur les figures 5a,5b),
  • un levier de déclenchement 17 (mieux visible sur la figure 6) comprenant une lumière 19 permettant le passage du pion d'ouverture 13, et
  • un mécanisme d'entraînement (figures 3,4) entraîné par le moteur 5, comprenant à titre d'exemple un levier de commande 21 relié d'une part au pêne 9 et au cliquet 11 et d'autre part à une roue dentée 23 via un pion 41, cette roue dentée 23 étant entraînée par le moteur 5, de façon à entraîner en pivotement le pêne 9 et le cliquet 11 pendant le verrouillage ou le déverrouillage.
Referring to Figures 3 and 4 the locking / unlocking mechanism 7 comprises:
  • a bolt 9 intended to cooperate with a striker (not shown),
  • a latch 11 for retaining the bolt 9 ( figure 4 )
  • an aperture counter 13 ( figure 4 ) carried by the ratchet 11,
  • a slide 15 (better visible on the Figures 5a, 5b )
  • a trigger lever 17 (better visible on the figure 6 ) comprising a light 19 allowing the passage of the aperture pin 13, and
  • a drive mechanism ( figures 3,4 ) driven by the motor 5, comprising by way of example a control lever 21 connected on the one hand to the bolt 9 and the pawl 11 and on the other hand to a toothed wheel 23 via a pin 41, this toothed wheel 23 being driven by the motor 5, so as to pivot the bolt 9 and the pawl 11 during locking or unlocking.

Le pêne et le cliquetThe bolt and the ratchet

Le pêne 9 (figures 3 et 4) présente par exemple une forme de fourche délimitant une ouverture 25 destinée à recevoir la gâche (non représentée) solidaire du véhicule.The bolt 9 ( Figures 3 and 4 ) has for example a form of fork defining an opening 25 for receiving the striker (not shown) secured to the vehicle.

Le pêne 9 est monté mobile en pivotement autour d'un axe de pivotement 27.The bolt 9 is pivotably mounted about a pivot axis 27.

Le pêne 9 présente encore au moins un logement 29 (voir figure 4) destiné à coopérer avec le cliquet 11. Le pêne 9 présente également un cran d'arrêt 30 pour coopérer avec le cliquet 11.The bolt 9 still has at least one housing 29 (see figure 4 ) to cooperate with the pawl 11. The bolt 9 also has a detent 30 to cooperate with the pawl 11.

Le cliquet 11 est soumis à une force de rappel élastique qui le sollicite vers le pêne 9. Et, le cliquet 11 présente par exemple un bec 31 qui vient en appui contre le cran d'arrêt 30 en position semi-fermée, et qui vient se loger dans le logement 29 du pêne 9 en position de verrouillage afin de maintenir le pêne 9 en position verrouillée.The pawl 11 is subjected to an elastic restoring force which urges it towards the bolt 9. And, the pawl 11 has for example a spout 31 which bears against the catch 30 in the half-closed position, and which comes housed in the housing 29 of the bolt 9 in the locking position to maintain the bolt 9 in the locked position.

On entend par position semi-fermée, une position dans laquelle la gâche (non représentée) est emprisonnée dans l'ouverture 25 du pêne 9, ce qui maintient la serrure fermée, mais le pêne 9 n'est pas bloqué en position de verrouillage.By semi-closed position is meant a position in which the strike (not shown) is trapped in the opening 25 of the bolt 9, which keeps the lock closed, but the bolt 9 is not locked in the locking position.

Pour cela, il faut que le bec 31 du cliquet 11 engage le logement 29 du pêne 9.For this, it is necessary that the spout 31 of the pawl 11 engages the housing 29 of the bolt 9.

Ainsi, le pêne 9 peut pivoter entre une position ouverte déverrouillée, une position semi-fermée et une position verrouillée.Thus, the bolt 9 can pivot between an unlocked open position, a semi-closed position and a locked position.

Le pion d'ouverture et le coulisseauThe opening pawn and the slider

Le pion d'ouverture 13 (figure 4) porté par le cliquet 11 est quant à lui monté de façon à traverser la lumière 19 du levier de déclenchement 17 (figure 6). Ce pion d'ouverture 13 est configuré pour réaliser un mouvement de pivotement selon une direction d'entraînement D1 représentée schématiquement par une flèche double sur la figure 3.The opening pawn 13 ( figure 4 ) carried by the pawl 11 is in turn mounted so as to pass through the light 19 of the trip lever 17 ( figure 6 ). This aperture pin 13 is configured to perform a pivoting movement in a drive direction D1 shown schematically by a double arrow on the figure 3 .

Le coulisseau 15 (figures 5a,5b) présente une came de guidage 33 pour coopérer avec le pion d'ouverture 13 de façon à entraîner la libération du pêne 9 par le cliquet 11 lors d'un mouvement de déverrouillage.The slider 15 ( Figures 5a, 5b ) has a guide cam 33 to cooperate with the aperture pin 13 so as to cause the release of the bolt 9 by the pawl 11 during an unlocking movement.

À cet effet, la came de guidage 33 présente une première surface de guidage 33a et une deuxième surface de guidage 33b. Ces deux surfaces de guidage 33a,33b sont opposées et le coulisseau 15 est agencé dans la serrure 1 de sorte que la came de guidage 33 et plus précisément les surfaces de guidage 33a,33b soient inclinées par rapport au plan de coulissement du coulisseau 15.For this purpose, the guide cam 33 has a first guide surface 33a and a second guide surface 33b. These two guide surfaces 33a, 33b are opposed and the slider 15 is arranged in the lock 1 so that the guide cam 33 and more precisely the guide surfaces 33a, 33b are inclined with respect to the sliding plane of the slider 15.

Le pion d'ouverture 13 est configuré pour coopérer avec la première surface de guidage 33a de façon à provoquer l'effacement du coulisseau 15 lors d'un mouvement de verrouillage, et pour coopérer avec la deuxième surface de guidage 33b de façon à entraîner le cliquet 11 vers la seconde position pour libérer le pêne 9.The aperture pin 13 is configured to cooperate with the first guiding surface 33a so as to cause the slider 15 to be erased during a locking movement, and to cooperate with the second guiding surface 33b so as to drive the ratchet 11 to the second position to release the bolt 9.

Pour l'agencement du coulisseau 15 dans la serrure 1, on peut prévoir par exemple que le coulisseau 15 présente une forme 34 complémentaire d'un logement 35 prévu dans le support 3 (voir figure 2).For the arrangement of the slider 15 in the lock 1, provision may be made, for example, for the slider 15 to have a shape 34 complementary to a recess 35 provided in the support 3 (see FIG. figure 2 ).

À titre d'exemple, le coulisseau 15 comporte une première face 15a portant la came de guidage 33 et une deuxième face 15b opposée à la première face 15a portant la forme complémentaire 34.By way of example, the slider 15 comprises a first face 15a carrying the guide cam 33 and a second face 15b opposite the first face 15a carrying the complementary form 34.

Selon le mode de réalisation illustré, le coulisseau 15 présente un corps principal de forme sensiblement parallélépipédique avec deux faces 15a,15b opposées. La came de guidage 33 forme une saillie sur la première face 15a du corps et la forme complémentaire 34 forme une saillie sur la deuxième face 15b du corps.According to the illustrated embodiment, the slider 15 has a main body of substantially parallelepiped shape with two opposite faces 15a, 15b. The guide cam 33 forms a projection on the first face 15a of the body and the complementary shape 34 forms a projection on the second face 15b of the body.

Ce coulisseau 15 est monté mobile en translation selon une direction D2 sensiblement transversale à la direction d'entraînement D1 du pion 13 (voir figure 3) entre :

  • une position de repos dans laquelle la came de guidage est agencée au niveau de la trajectoire du pion 13, et
  • une position d'effacement dans laquelle le coulisseau 15 s'efface pour libérer la trajectoire du pion 13.
This slider 15 is mounted to move in translation in a direction D2 substantially transverse to the driving direction D1 of the pin 13 (see FIG. figure 3 ) enter :
  • a rest position in which the guide cam is arranged at the trajectory of the pin 13, and
  • an erasure position in which the slider 15 is erased to release the trajectory of the pin 13.

On peut prévoir un moyen de rappel élastique, tel qu'un ressort 37, monté à une extrémité 39 complémentaire du coulisseau 15, par exemple à une extrémité 39 de la forme 34 (figures 3 et 5a).An elastic return means may be provided, such as a spring 37, mounted at a complementary end 39 of the slider 15, for example at an end 39 of the shape 34 ( figures 3 and 5a ).

Le coulisseau 15 est donc mobile entre la position de repos et la position d'effacement.The slider 15 is movable between the rest position and the erasing position.

De ce fait en position de repos, le coulisseau 15 ne peut coulisser que dans un sens : vers la position d'effacement. Une butée est donc prévue pour empêcher la translation du coulisseau 15 depuis la position de repos vers l'opposé de la position d'effacement.As a result, in the rest position, the slider 15 can only slide in one direction: towards the erasing position. A stop is therefore provided to prevent the translation of the slider 15 from the rest position to the opposite of the erasing position.

En position d'effacement, ou en position intermédiaire, le coulisseau 15 est rappelé en position de repos par exemple par le ressort 37.In the erasing position, or in the intermediate position, the slider 15 is returned to the rest position, for example by the spring 37.

Levier de déclenchementTrigger lever

Le levier de déclenchement 17 (figure 6) est relié mécaniquement au cliquet 11.The trigger lever 17 ( figure 6 ) is mechanically connected to the pawl 11.

De plus la lumière 19 de ce levier de déclenchement 17 est traversée par le pion d'ouverture 13 et présente une forme adaptée à la trajectoire de ce pion d'ouverture 13.In addition, the light 19 of this trigger lever 17 is traversed by the aperture pin 13 and has a shape adapted to the trajectory of this aperture pin 13.

Dans l'exemple illustré, la lumière 19 présente une forme sensiblement oblongue et incurvée.In the illustrated example, the light 19 has a substantially oblong and curved shape.

Ce levier de déclenchement 17 a pour fonction de bloquer le cliquet 11 pendant le mouvement de déverrouillage, notamment en cas de charge sur l'ouvrant.This trigger lever 17 has the function of blocking the pawl 11 during the unlocking movement, especially in case of load on the leaf.

Par exemple, en cas de neige ou toute autre charge sur l'ouvrant, tel que le coffre, il est possible que l'ouvrant ne puisse pas bouger et le pêne 9 ne pivote pas de suite vers la position déverrouillée. Le cliquet 11 soumis à une force de rappel élastique peut alors engager de nouveau le pêne 9 et le bloquer de nouveau en position verrouillée. L'utilisateur doit alors recommencer la procédure de déverrouillage.For example, in case of snow or other load on the door, such as the trunk, it is possible that the door can not move and the bolt 9 does not rotate immediately to the unlocked position. The pawl 11 subjected to an elastic restoring force can then engage the bolt 9 again and lock it again in the locked position. The user must then restart the unlocking procedure.

Le levier de déclenchement 17 permet de bloquer le cliquet 11 dans une position écartée du pêne 9, de sorte que ce pêne 9 puisse pivoter de manière à libérer à son tour la gâche.The release lever 17 serves to lock the pawl 11 in a position spaced from the bolt 9, so that the bolt 9 can pivot so as to release the latch in turn.

Mécanisme d'entraînementDriving mechanism

En ce qui concerne le mécanisme d'entraînement par le moteur 5 selon le mode de réalisation illustré, la roue dentée 23 est mobile en rotation autour de son axe central 24 et le levier de commande 21 est entraîné en pivotement par coopération de forme entre la roue dentée 23 et le levier de commande 21. Plus précisément, le levier de commande 21 est entraîné en pivotement par le déplacement du pion 41 solidaire de la roue dentée 23 dans une fente associée du levier de commande 21.With regard to the drive mechanism by the motor 5 according to the illustrated embodiment, the toothed wheel 23 is rotatable about its central axis 24 and the control lever 21 is pivotally driven by shape cooperation between the toothed wheel 23 and the control lever 21. More precisely, the control lever 21 is pivotally driven by the displacement of the pin 41 integral with the toothed wheel 23 in an associated slot of the control lever 21.

Ce levier de commande 21 entraîne le pêne 9 et le cliquet 11 en pivotement.This control lever 21 drives the bolt 9 and the pawl 11 pivoting.

Bien entendu, tout autre mécanisme d'entraînement peut être choisi et mis en oeuvre par l'Homme du métier selon ses souhaits.Of course, any other drive mechanism can be chosen and implemented by the skilled person according to his wishes.

Fonctionnement de la serrure motoriséeOperation of the motorized lock

En référence aux figures 7a à 7e et 8a, 8b, on décrit maintenant le fonctionnement de la serrure 1 pendant un mouvement de verrouillage puis pendant un mouvement de déverrouillage.With reference to Figures 7a to 7e and 8a, 8b , the operation of the lock 1 during a locking movement and during an unlocking movement is now described.

Pour faciliter la compréhension sur ces figures, le support 3 est représenté en transparence et seules les surfaces de guidage 33a et 33b du coulisseau 15 sont représentées. Le reste du coulisseau 15 n'est pas illustré.To facilitate understanding in these figures, the support 3 is shown in transparency and only the guide surfaces 33a and 33b of the slider 15 are shown. The rest of the slider 15 is not illustrated.

De plus, dans ces figures la position du pêne 9 est représentée de façon approximative.Moreover, in these figures the position of the bolt 9 is represented so rough.

Concernant le verrouillage :Concerning the lock:

La figure 7a illustre de façon schématique et simplifiée la serrure 1 en position ouverte déverrouillée. Dans cette position, la gâche (non représentée) n'est pas emprisonnée par le pêne 9 et le pion 13 se situe au-dessus de la première surface de guidage 33a du coulisseau 15.The figure 7a schematically and simplifies the lock 1 in unlocked open position. In this position, the strike (not shown) is not trapped by the bolt 9 and the pin 13 is above the first guide surface 33a of the slide 15.

La figure 7b illustre de façon schématique et simplifiée la serrure 1 en position semi-fermée, entraînant un mouvement de pivotement du pêne jusqu'à ce que le cliquet 11 sollicité élastiquement coopère avec le cran d'arrêt 30 du pêne 9. Le pion 13 se situe toujours au-dessus de la première surface de guidage 33a du coulisseau 15.The figure 7b illustrates schematically and simplified lock 1 in the semi-closed position, causing a pivoting movement of the bolt until the pawl 11 resiliently biased cooperates with the catch 30 of the bolt 9. The pin 13 is always above the first guide surface 33a of the slider 15.

Lorsque le moteur 5 est actionné pour le verrouillage et tourne dans un premier sens de rotation horaire illustré par la flèche F1, il entraîne le mécanisme d'actionnement 7 et en particulier le pion d'ouverture 13 porté par le cliquet 11 en pivotement.When the motor 5 is actuated for locking and rotates in a first clockwise direction illustrated by the arrow F1, it drives the actuating mechanism 7 and in particular the aperture pin 13 carried by the pawl 11 pivotally.

Plus en détail selon le mode réalisation illustré, le moteur 5 entraîne en rotation la roue dentée 23 dans un second sens de rotation anti-horaire illustré par la flèche F2. Par son mouvement de rotation la roue dentée 23 entraîne le levier de commande 21 en pivotement sensiblement vers le bas en référence aux figures 7b,7c. Et ce levier de commande 21 entraîne à son tour en pivotement d'une part le pêne 9 et d'autre part le cliquet 11 portant le pion d'ouverture 13.In more detail according to the illustrated embodiment, the motor 5 rotates the toothed wheel 23 in a second direction of anti-clockwise rotation illustrated by the arrow F2. By its rotational movement the toothed wheel 23 drives the control lever 21 to pivot substantially downwards with reference to the Figures 7b, 7c . And this control lever 21 in turn rotates on the one hand the bolt 9 and on the other hand the pawl 11 carrying the aperture pin 13.

Comme on le remarque sur la figure 7c, le pion 13 porté par le cliquet 11 en pivotement, décrit une trajectoire de pivotement selon la direction d'entraînement D1 dans un premier sens, ici dans un sens descendant illustré par la flèche F3, jusqu'à venir en contact avec la première surface de guidage 33a de la came de guidage 33 du coulisseau 15.As we notice on the Figure 7c , the pin 13 carried by the pawl 11 in pivoting, describes a pivoting trajectory in the direction of the drive D1 in a first direction, here in a downward direction illustrated by the arrow F3, until coming into contact with the first surface guide 33a of the guide cam 33 of the slider 15.

Le pion 13 exerce alors une poussée sur le coulisseau 15 et étant donnée l'inclinaison de la première surface de guidage 33a, le coulisseau 15 est poussé vers la position d'effacement selon une direction D2, comme l'illustre la flèche F4, en comprimant le ressort 37. Le coulisseau 15 libère ainsi la trajectoire du pion 13 (figure 7d) qui continue sa trajectoire selon la flèche F3.The pin 13 then exerts a thrust on the slider 15 and given the inclination of the first guide surface 33a, the slider 15 is pushed to the erasing position in a direction D2, as shown by the arrow F4, in compressing the spring 37. The slider 15 thus releases the trajectory of the pin 13 ( figure 7d ) which continues its trajectory according to the arrow F3.

De plus, le pêne 9 est également entraîné en pivotement par le levier de commande 21, jusqu'à ce que le bec 31 du cliquet 11 sollicité élastiquement s'engage dans le logement 29 du pêne 9.In addition, the bolt 9 is also pivotally driven by the control lever 21, until the spout 31 of the resiliently biased pawl 11 engages in the housing 29 of the bolt 9.

Une fois le pion 13 passé, le coulisseau 15 est rappelé élastiquement par le ressort 37 en positon de repos et se place à nouveau sur la trajectoire du pion 13 désormais en dessous du coulisseau 15 (figure 7e).Once the pin 13 has passed, the slider 15 is resiliently biased by the spring 37 in the rest position and is placed again on the path of the pin 13 now below the slider 15 ( figure 7e ).

Ainsi, la gâche (non représentée) est emprisonnée par le pêne 9 maintenu dans cette position de verrouillage par le cliquet 11; le pion 13 lui se situant en dessous de la deuxième surface de guidage 33b du coulisseau 15.Thus, the striker (not shown) is trapped by the bolt 9 held in this locking position by the pawl 11; the pin 13 being located below the second guide surface 33b of the slider 15.

Concernant le déverrouillage :Regarding unlocking:

Partant de la position de verrouillage illustrée sur la figure 7e, lorsque le moteur 5 est actionné pour le déverrouillage, il tourne dans le second sens de rotation anti-horaire illustré par la flèche F2 de façon à entraîner le mécanisme d'actionnement 7.Starting from the locking position illustrated on the figure 7e when the motor 5 is actuated for unlocking, it rotates in the second anti-clockwise direction illustrated by the arrow F2 so as to drive the actuating mechanism 7.

Plus en détail selon le mode réalisation illustré, le moteur 5 entraîne en rotation la roue dentée 23 dans le premier sens de rotation horaire illustré par la flèche F1. Par son mouvement de rotation la roue dentée 23 entraîne le levier de commande 21, ici sensiblement vers le bas par rapport aux figures 7e et 8a, qui entraîne à son tour en pivotement le pêne 9 et le cliquet 11 portant le pion d'ouverture 13.In more detail according to the illustrated embodiment, the motor 5 rotates the toothed wheel 23 in the first clockwise direction illustrated by the arrow F1. By its rotational movement the toothed wheel 23 drives the control lever 21, here substantially downwards relative to the Figures 7e and 8a , which in turn rotates the bolt 9 and the pawl 11 carrying the aperture pin 13.

Comme on le remarque sur la figure 8a, le pion 13 décrit une trajectoire de pivotement selon la direction d'entraînement D1 dans un second sens opposé au premier sens, ici dans un sens ascendant illustré par la flèche F5, jusqu'à venir en contact avec la deuxième surface de guidage 33b de la came de guidage 33 du coulisseau 15.As we notice on the figure 8a , the pin 13 describes a pivoting trajectory in the direction of drive D1 in a second direction opposite to the first direction, here in an upward direction illustrated by the arrow F5, until coming into contact with the second guide surface 33b of the guide cam 33 of the slide 15.

Le pion 13 exerce donc une poussée sur le coulisseau 15 et étant donnée l'inclinaison de la deuxième surface de guidage 33b et le fait qu'en position de repos le coulisseau 15 ne peut coulisser que vers la position d'effacement selon la direction D2, le coulisseau 15 reste fixe en position de repos et c'est le pion 13 qui est dévié sensiblement selon la direction D2 en même temps qu'il continue son mouvement selon la direction D1 (figure 8b).The pin 13 thus exerts a thrust on the slider 15 and given the inclination of the second guide surface 33b and the fact that in the rest position the slider 15 can slide only towards the erasing position in the direction D2 , the slider 15 remains fixed in the rest position and it is the pin 13 which is deviated substantially in the direction D2 at the same time as it continues its movement in the direction D1 ( figure 8b ).

Le cliquet 11 portant le pion 13 s'écarte donc du pêne 9 et le bec 31 du cliquet 11 libère le logement 29 du pêne 9 qui libère à son tour la gâche (non représentée). On se retrouve en position ouverte déverrouillée illustrée par la figure 7a.The pawl 11 carrying the pin 13 therefore deviates from the bolt 9 and the spout 31 of the pawl 11 releases the housing 29 of the bolt 9 which in turn releases the striker (not shown). We find ourselves in unlocked open position illustrated by the figure 7a .

Ainsi, avec un seul moteur et en prévoyant dans le mécanisme de verrouillage/déverrouillage le pion d'ouverture 13 et son coulisseau 15 avec une came de guidage 33 à double surfaces inclinées 33a,33b, on peut de façon simple commander avec le même moteur le verrouillage ou le déverrouillage sans nécessiter par exemple de tringle supplémentaire. Ceci est particulièrement avantageux pour un toit ouvrant de véhicule.Thus, with a single motor and by providing in the locking / unlocking mechanism the aperture pin 13 and its slide 15 with a guide cam 33 with double inclined surfaces 33a, 33b can be controlled in a simple manner with the same motor. locking or unlocking without requiring for example additional rod. This is particularly advantageous for a vehicle sunroof.
