Description

L'invention est relative à un dispositif d'ouverture d'une serrure de véhicule, du type comportant un actionneur ou moteur électrique commandé par un organe de commande électrique.The invention relates to a device for opening a vehicle lock, of the type comprising an actuator or motor electric controlled by an electric control member.

Les serrures de porte, de hayon ou de coffre de véhicule comportent généralement un pêne de fermeture verrouillé par un cliquet de verrouillage. Pour augmenter la résistance à l'effraction des véhicules, la technique évolue vers l'utilisation de serrures entièrement électriques dans lesquelles les commandes mécaniques accessibles ou visibles de l'extérieur du véhicule sont supprimées. Cette évolution résulte de la constatation selon laquelle la superposition de commandes d'ouverture électrique et mécanique n'assure pas une sécurité suffisante contre l'effraction.Door, tailgate or trunk locks generally include a locking bolt locked by a locking pawl. To increase the resistance to burglary vehicles, the technique is evolving towards the use of fully locks in which the accessible mechanical controls or visible from outside the vehicle are removed. That evolution results from the finding that the overlapping of orders electrical and mechanical opening does not provide sufficient security against break-in.

Cependant, les serrures entièrement électriques ne permettent pas de vaincre les efforts exceptionnels appliqués à la serrure dans le cas d'une porte ou d'un habitacle faussé ou déformé par des chocs. En effet, en cas d'efforts normaux, l'ouverture de la porte nécessite de vaincre la réaction de joint appliquée au contact entre la gâche et le pêne de la serrure, de l'ordre de 500 N, qui correspond à un effort pouvant être obtenu par des serrures entièrement électriques ; tandis que, en cas d'efforts exceptionnels, l'effort à vaincre peut être de l'ordre de 7 500 N, ce qui correspond à un effort ne pouvant généralement pas être obtenu avec des serrures entièrement électriques qui ne mettent en oeuvre que des moteurs de faible puissance pour tenir compte des impératifs de coût et d'encombrement.However, fully electric locks do not not overcome the exceptional efforts applied to the lock in the case of a door or cabin distorted or deformed by shocks. Indeed, in case of normal efforts, the opening of the door requires to overcome the joint reaction applied to the contact between the keeper and the bolt of the lock, of the order of 500 N, which corresponds to an effort which can be obtained by fully electric locks; while, in the case of exceptional efforts, the effort to be overcome may be around 7,500 N, which corresponds to an effort that cannot generally not be obtained with fully electric locks which use only low power motors to hold account of cost and space requirements.

L'invention a pour but de perfectionner les serrures entièrement électriques, notamment les serrures appelées par l'homme du métier "serrures à commande électrique et secours électrique intégré", en permettant l'ouverture du véhicule même en cas d'efforts exceptionnels et en conservant les avantages de sécurité anti-effraction des serrures entièrement électriques.The object of the invention is to improve the locks fully electric, including man-made locks of the trade "electrically operated locks and electrical backup integrated ", allowing the opening of the vehicle even in the event of efforts exceptional and retaining the burglary security advantages fully electric locks.

L'invention a pour objet un dispositif d'ouverture d'une serrure de véhicule, du type comportant un actionneur ou moteur électrique commandé par un organe de commande électrique, caractérisé par le fait que l'organe de commande électrique est conformé pour commander mécaniquement un organe de déblocage agissant directement sur le pêne de la serrure, de manière à débloquer le pêne pour permettre l'ouverture électrique de la serrure en présence d'efforts exceptionnels s'exerçant sur ledit pêne.The subject of the invention is a device for opening a vehicle lock, of the type comprising an actuator or motor electric controlled by an electric control unit, characterized by the fact that the electrical control member is shaped to mechanically control an unlocking member acting directly on the bolt of the lock, so as to unlock the bolt to allow the electric opening of the lock in the presence exceptional efforts exerted on said bolt.

Selon d'autres caractéristiques de l'invention :

  • l'organe de commande électrique est actionnable selon deux modes de fonctionnement complémentaires, dont le premier correspond à une commande électrique de la serrure en présence d'efforts normaux et dont le deuxième correspond à une commande mécanique de l'organe de déblocage, en présence d'efforts exceptionnels, suivie d'une commande électrique de la serrure ;
  • ledit premier mode de fonctionnement est obtenu par une course faible d'actionnement de l'organe de commande électrique et ledit deuxième mode de fonctionnement est obtenu par une course longue d'actionnement de l'organe de commande électrique ;
  • l'organe de déblocage comporte au moins deux leviers articulés, à la manière d'une genouillère, en un point d'articulation dont le déplacement est commandé mécaniquement ;
  • la commande mécanique du déplacement de la genouillère est une commande par liaison souple, en particulier par câble ;
  • la conformation du pêne est une conformation prismatique ;
  • la conformation du pêne vient de matière d'une seule pièce avec le pêne ;
  • la conformation du pêne correspond à un évidement du pêne ou à une pièce rapportée fixée par un évidement du pêne.
According to other characteristics of the invention:
  • the unlocking member comprises a sliding end exerting a push on a conformation of the bolt;
  • the end of the unlocking member is shaped to slide in two sliding directions, the first of which corresponds to an approach towards the bolt and the second corresponds to a distance from the bolt after unlocking;
  • the electrical control member can be actuated according to two complementary operating modes, the first of which corresponds to an electrical control of the lock in the presence of normal forces and the second of which corresponds to a mechanical control of the release member, in the presence exceptional efforts, followed by an electric control of the lock;
  • said first operating mode is obtained by a short actuation stroke of the electric control member and said second operating mode is obtained by a long actuation stroke of the electric control member;
  • the unlocking member comprises at least two levers articulated, in the manner of a toggle joint, at a point of articulation whose movement is mechanically controlled;

  • the conformation of the bolt is a prismatic conformation;
  • the conformation of the bolt comes in one piece with the bolt;
  • the conformation of the bolt corresponds to a recess in the bolt or to an attached part fixed by a recess in the bolt.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en se référant au dessin annexé. The invention will be better understood thanks to the description which will follow given by way of nonlimiting example with reference to the drawing Annex.

Sur ce dessin :

  • la figure 1 représente schématiquement une vue en perspective d'un dispositif selon l'invention ;
  • la figure 2 représente schématiquement une vue partielle en perspective de la serrure de la figure 1 dans une position de déblocage.
On this drawing :
  • Figure 1 schematically shows a perspective view of a device according to the invention;
  • 2 schematically shows a partial perspective view of the lock of Figure 1 in an unlocked position.

Sur la figure 1, on voit qu'un dispositif selon l'invention comporte un actionneur ou moteur électrique non représenté apte à déplacer un cliquet de verrouillage 1 coopérant avec un pêne 2. Le cliquet 1 comporte un bec de verrouillage la apte à retenir en position des crans du cliquet, tels que le cran 2a correspondant à la fermeture d'une porte, d'un hayon ou coffre de véhicule. L'actionneur ou moteur électrique non représenté doit vaincre un effort produit au contact du bec la et du cran 2a pour déverrouiller la serrure du véhicule. Dans le cas d'un effort normal de déverrouillage, de l'ordre de 500 N, le cliquet de verrouillage 1 pivote vers le bas autour de l'axe 1b, ce qui libère le pivotement du pêne 2 autour de l'axe 2b et permet donc l'ouverture de la porte ou, plus généralement, de l'ouvrant associé à la serrure. Les axes 1b et 2b sont des axes matériels schématisés par des axes géométriques en traits interrompus, et ces axes matériels 1b, 2b, sont solidaires du support 3 de montage de la serrure sur l'ouvrant du véhicule, ce montage étant effectué par exemple au moyen de vis passant par les ouvertures 4a et 4b du support 3.In FIG. 1, it can be seen that a device according to the invention comprises an actuator or electric motor, not shown, capable of move a locking pawl 1 cooperating with a bolt 2. The pawl 1 has a locking spout capable of retaining it in position notches of the pawl, such as notch 2a corresponding to the closure a door, a tailgate or a vehicle trunk. The actuator or motor electric not shown must overcome an effort produced in contact with the beak and notch 2a to unlock the vehicle lock. In the in the event of a normal unlocking effort, of the order of 500 N, the locking pawl 1 pivots down around axis 1b, which releases the pivoting of the bolt 2 around the axis 2b and therefore allows the opening of the door or, more generally, of the opening associated with the lock. Axes 1b and 2b are material axes schematized by geometric axes in dashed lines, and these material axes 1b, 2b, are integral with the support 3 for mounting the lock on the opening of the vehicle, this assembly being carried out for example by means of screws passing through the openings 4a and 4b of the support 3.

L'actionneur ou moteur électrique non représenté du pêne 1 est commandé par un organe de commande électrique 5, qui comporte un interrupteur ou un moyen électrique d'émission d'un signal de commande d'un circuit d'ouverture ou de fermeture et une commande manuelle actionnable suivant deux modes de fonctionnement. Le premier mode de fonctionnement correspond à une commande électrique de la serrure en présence d'efforts normaux d'ouverture de l'ordre de 500 N. Le deuxième mode de fonctionnement correspond à une commande mécanique d'un organe de déblocage, en présence d'efforts exceptionnels de l'ordre de 7 500 N, suivie d'une commande électrique de la serrure. L'organe 5 comporte une palette Sa sur laquelle s'exerce l'action de l'utilisateur. The actuator or electric motor not shown of the bolt 1 is controlled by an electrical control member 5, which includes a switch or an electrical means for transmitting a control signal of an opening or closing circuit and a manual control operable in two modes operation. The first operating mode corresponds to a electric control of the lock in the presence of normal forces opening time of around 500 N. The second operating mode corresponds to a mechanical control of an unlocking member, in presence of exceptional efforts of the order of 7,500 N, followed by a electric control of the lock. The member 5 includes a palette Sa on which the action of the user is exerted.

De préférence, le premier mode de fonctionnement est obtenu par une course faible d'actionnement de l'organe électrique de commande, par exemple par une faible levée de la palette Sa, et le deuxième mode de fonctionnement est obtenu par une course longue de l'organe électrique de commande, par exemple par une levée importante de la palette 5a.Preferably, the first mode of operation is obtained by a short actuation stroke of the electrical member of control, for example by a low lift of the Sa pallet, and the second operating mode is obtained by a long stroke of the electrical control member, for example by lifting important from palette 5a.

L'invention n'est pas limitée à la levée d'une palette Sa, mais s'étend également à des courses différentes d'un autre organe de commande manuelle, par exemple au moyen d'une clé ou d'un organe rotatif.The invention is not limited to lifting a Sa pallet, but also extends to different races of another organ of manual control, for example by means of a key or a member rotary.

Selon l'invention, l'organe électrique de commande 5 est conformé pour commander mécaniquement un organe 6 de déblocage agissant directement sur le pêne 2 de la serrure, de manière à débloquer le pêne 2 en présence d'efforts exceptionnels pour permettre l'ouverture électrique de la serrure. L'organe de déblocage 6 comporte une extrémité coulissante 6a exerçant une poussée sur une conformation 7 du pêne 2.According to the invention, the electrical control member 5 is shaped to mechanically control an unlocking member 6 acting directly on the bolt 2 of the lock, so as to unlock the bolt 2 in the presence of exceptional efforts to allow the electric opening of the lock. The release member 6 comprises a sliding end 6a pushing on a conformation 7 of the bolt 2.

Sur la réalisation représentée, l'organe de déblocage 6 comporte au moins deux leviers 6b, 6c articulés entre eux en un point d'articulation 6d, dont le déplacement est commandé mécaniquement. Le levier 6c est articulé à une de ses extrémités sur un axe solidaire du support 3 et à son autre extrémité en 6d avec le levier 6b ; ce levier 6b est articulé avec un coulisseau 6a, de manière à commander un coulissement du coulisseau 6a selon deux sens de coulissement, dont le premier est en direction du pêne 2 et le second correspond à la direction opposée, en retrait par rapport au pêne 2.In the embodiment shown, the release member 6 comprises at least two levers 6b, 6c hinged together at a point articulation 6d, whose movement is mechanically controlled. The lever 6c is articulated at one of its ends on an axis integral with the support 3 and at its other end in 6d with the lever 6b; this lever 6b is articulated with a slide 6a, so as to control a sliding of the slide 6a in two sliding directions, the first is towards the bolt 2 and the second corresponds to the opposite direction, set back from the bolt 2.

L'organe de déblocage 6 fonctionne à la manière d'une genouillère dont le point d'articulation 6d est déplacé à l'aide d'une commande mécanique, qui est une commande par un câble 8. La commande par câble 8 est une commande de type connu à rappel élastique et à gaine 9, montée entre le support 3 et l'organe de commande électrique 5.The release member 6 operates in the manner of a knee brace whose point of articulation 6d is moved using a mechanical control, which is a control by a cable 8. The cable control 8 is a control of known type with recall elastic and sheath 9, mounted between the support 3 and the electric control 5.

Le pêne 2 comporte, en un point opposé au cran de retenue 2a par rapport à l'axe 2b, une conformation 7. La conformation 7 est avantageusement une conformation prismatique présentant un plan ou une surface de poussée propre à recevoir la poussée de l'extrémité coulissante du coulisseau 6a. La conformation 7 est venue de matière d'une seule pièce avec le pêne 2, mais pourrait également correspondre à un évidement du pêne, ou à une pièce rapportée fixée à un évidement du pêne 2.The bolt 2 has, at a point opposite the retaining notch 2a with respect to the axis 2b, a conformation 7. The conformation 7 is advantageously a prismatic conformation having a plane or a push surface suitable for receiving the push from the end sliding of the slide 6a. The conformation 7 came from matter in one piece with bolt 2, but could also match to a recess in the bolt, or to an attached piece attached to a recess of the bolt 2.

Sur la figure 2, le dispositif est représenté partiellement dans une position correspondant au déblocage du pêne 2. Dans cette position, le coulisseau 6a appuie sur la conformation 7 du pêne 2 et produit un effort de déblocage permettant de vaincre des efforts exceptionnels. La poussée du coulisseau 6a sur le prisme 7 correspond à un effort important qui provoque un léger pivotement du pêne 2 autour de l'axe 2b et un déblocage du contact entre le bec de verrouillage la du cliquet 1 et le cran de retenue 2a du pêne 2. Le déblocage est suffisant pour vaincre les efforts exceptionnels, mais ne provoque pas le déverrouillage et donc l'ouverture de la serrure. L'annulation des efforts exceptionnels permet le déverrouillage et l'ouverture électrique de la serrure par l'actionneur ou le moteur électrique non représenté et connu en soi.In Figure 2, the device is shown partially in a position corresponding to the release of the bolt 2. In this position, the slide 6a presses on the conformation 7 of the bolt 2 and produces an unlocking effort to overcome efforts exceptional. The thrust of the slide 6a on the prism 7 corresponds at a significant effort which causes a slight pivoting of the bolt 2 around the axis 2b and a release of the contact between the spout locking of the pawl 1 and the retaining notch 2a of the bolt 2. The unlocking is enough to defeat exceptional efforts, but don't not cause the unlocking and therefore the opening of the lock. The cancellation of exceptional efforts allows the unlocking and electric opening of the lock by the actuator or the motor electric not shown and known per se.

Pour permettre cette ouverture électrique, après avoir provoqué le déblocage du contact entre le cliquet de verrouillage et le pêne de la serrure, la genouillère 6 provoque le retrait du coulisseau 6a lors du passage des leviers 6b et 6c dans la position représentée en traits interrompus sur la figure 2.To allow this electric opening, after having caused the contact between the locking pawl and the bolt of the lock, the toggle 6 causes the slide 6a to be withdrawn when the levers 6b and 6c pass into the position shown in broken lines in Figure 2.

L'organe de déblocage 6 assure ainsi une assistance mécanique de décompression du système pêne/cliquet lors de la présence d'efforts exceptionnels mais ne participe pas à l'ouverture électrique de la porte : les avantages de sécurité anti-effraction des serrures entièrement électriques sont, par conséquent, entièrement conservés par la présente invention.The release member 6 thus provides assistance mechanical decompression of the bolt / ratchet system during presence of exceptional efforts but does not participate in the opening door security: the burglar-proof security advantages of fully electric locks are, therefore, fully preserved by the present invention.

En effet, la traction exercée par l'actionneur électrique non représenté sur le cliquet de verrouillage 1 et symbolisée par la flèche F correspond à un effort modéré pouvant toujours être obtenu par une commande et un actionnement entièrement électriques, dès que le contact entre pêne et cliquet est débloqué par l'organe 6 de déblocage.Indeed, the traction exerted by the electric actuator not represented on the locking pawl 1 and symbolized by the arrow F corresponds to a moderate effort which can always be obtained by a fully electric control and actuation, as soon as the contact between bolt and pawl is released by the unlocking member 6.

Dans ce mode préféré de réalisation de l'invention, on prévoit que le pivotement du pêne 2 résultant de l'action de l'organe de déblocage 6 est suffisant pour rompre le contact entre pêne et cliquet, ce qui assure, dans tous les cas, la libération du cliquet et permet sa traction vers le bas par un actionneur électrique exerçant la force F pour déverrouiller et ouvrir la serrure de la porte, du hayon ou du coffre de véhicule.In this preferred embodiment of the invention, it is provides that the pivoting of the bolt 2 resulting from the action of the release 6 is sufficient to break the contact between latch and ratchet, which ensures, in all cases, the release of the pawl and allows its pulling down by an electric actuator exerting the force F to unlock and open the door, tailgate or door lock vehicle trunk.

L'invention décrite en référence à un mode de réalisation particulier n'y est nullement limitée et couvre, au contraire, toutes modifications de forme et toutes variantes de réalisation de l'invention, dans lesquelles une commande mécanique d'un organe de déblocage annule les efforts exceptionnels et libère l'ouverture entièrement électrique de la serrure de véhicule.The invention described with reference to an embodiment particular is in no way limited to it and covers, on the contrary, all modifications of form and all variant embodiments of the invention, in which a mechanical control of an unlocking member cancels the exceptional efforts and frees the opening entirely electric vehicle lock.
