Abstract

The lock has a pivoted bolt (6) co-operating with a staple (6) formed in the bodywork. The electric motor (9) is geared (10) to a rotary disc (11) with two crankpins (13,14) which pivot the catch (8) into its unlocked position. The levers (15,17) connect the disc to the catch. The disc continues to rotate until the crankpins pass over the end (23) of one lever (15) and are disengaged from the device (18) driving the catch, which is returned to its locked position by a spring (21).

Description

L'invention concerne une serrure pour un ouvrant de véhicule automobile, notamment une portière.The invention relates to a lock for a door leaf of a motor vehicle, in particular a door.

L'invention concerne plus spécifiquement une serrure comportant un pêne pivotant qui, lorsque la portière est fermée, entoure une gâche agencée dans la carrosserie du véhicule, le pêne pouvant être bloqué au moyen d'un cliquet d'arrêt pivotant et le cliquet d'arrêt pouvant, pour l'ouverture de la portière, pivoter d'une position de blocage à une position de déblocage à l'encontre de la pression d'un ressort, au moyen d'un moteur électrique équipé d'un engrenage, serrure dans laquelle :

  • a) l'engrenage entraîne un disque rotatif à manetons qui porte au moins un maneton ;
  • b) le maneton s'engrène directement ou par l'intermédiaire d'au moins un levier de liaison sur un entraîneur du cliquet d'arrêt, de telle sorte que
  • c) lors de l'opération d'ouverture, en tournant le disque à manetons, le maneton fait d'abord pivoter le cliquet d'arrêt dans sa position de déblocage, et
  • d) le disque à manetons continue ensuite à tourner jusqu'à ce que le maneton se trouve hors de coopération avec l'entraîneur du cliquet d'arrêt ou du levier de liaison et le cliquet d'arrêt est ramené à pivotement par son ressort dans sa position de blocage.
The invention relates more specifically to a lock comprising a pivoting bolt which, when the door is closed, surrounds a keeper arranged in the vehicle body, the bolt being able to be locked by means of a pivoting stop pawl and the pawl. stop that can, for opening the door, pivot from a locking position to an unlocking position against the pressure of a spring, by means of an electric motor equipped with a gear, lock in which :
  • a) the gear drives a rotary crankpin disc which carries at least one crankpin;
  • b) the crank pin engages directly or by means of at least one connecting lever on a drive of the stop pawl, so that
  • c) during the opening operation, by turning the crank disc, the crank pin first rotates the stop pawl to its unlocked position, and
  • d) the crank disc then continues to rotate until the crank pin is out of cooperation with the driver of the stop pawl or of the link lever and the pawl is pivotally returned by its spring in its blocking position.

On connaît, par exemple par DE 32 42 527 A1, une serrure pour une portière de véhicule automobile munie, du côté de la portière, d'un pêne pivotant qui, lorsque la portière est fermée, entoure une gâche et est bloqué au moyen d'un cliquet ou cran d'arrêt pivotant. Le cliquet d'arrêt peut pivoter d'une position de blocage à une position de déblocage au moyen d'un excentrique tournant qui est relié à un moteur électrique par l'intermédiaire d'un engrenage. Le principal inconvénient de cette serrure connue est que la commande du cliquet d'arrêt par l'intermédiaire de l'engrenage et de l'excentrique prend relativement beaucoup de place. En outre, le cliquet d'arrêt reste dans la position de déblocage jusqu'à ce que l'excentrique tourne d'un angle supérieur à 180°. Lorsque l'excentrique coince ou lors d'une panne de courant, on ne peut que très difficilement refaire pivoter le cliquet d'arrêt dans sa position de blocage.We know, for example from DE 32 42 527 A1, a lock for a door of a motor vehicle provided, on the side of the door, with a pivoting bolt which, when the door is closed, surrounds a keeper and is locked by means of '' a pivoting ratchet or catch. The stop pawl can pivot from a locking position to an unlocking position by means of a rotating eccentric which is connected to an electric motor by means of a gear. The main drawback of this known lock is that the control of the pawl via the gear and the eccentric takes up a relatively large amount of space. In addition, the stop pawl remains in the unlocked position until the eccentric turns by an angle greater than 180 °. When the eccentric jams or during a breakdown of current, it is very difficult to re-pivot the stop pawl to its locked position.

L'invention a pour objet de proposer une serrure du type mentionné ci-dessus selon laquelle le cliquet d'arrêt revient le plus vite possible dans sa position de blocage après avoir atteint sa position de déblocage. En outre, la serrure doit pouvoir être montée en prenant le moins de place possible.The object of the invention is to provide a lock of the type mentioned above according to which the stop pawl returns as quickly as possible to its blocking position after having reached its unlocking position. In addition, the lock must be able to be mounted taking up as little space as possible.

Ce problème est résolu selon l'invention par le fait que :

  • le cliquet d'arrêt comporte un entraîneur en forme de pion,
  • deux leviers de liaison, agencés l'un derrière l'autre et pouvant pivoter autour d'un même axe, sont prévus entre le disque à manetons et le cliquet d'arrêt, de telle sorte que
  • pour faire pivoter le cliquet d'arrêt dans sa position de déblocage, le maneton peut faire pivoter le premier levier de liaison proche du disque à manetons et que le second levier de liaison entraîne l'entraîneur du cliquet d'arrêt.
This problem is solved according to the invention by the fact that:
  • the pawl includes a pawn-shaped coach,
  • two connecting levers, arranged one behind the other and able to pivot about the same axis, are provided between the crank disc and the pawl, so that
  • to rotate the stop pawl to its unlocked position, the crankpin can rotate the first link lever close to the crankpin disc and the second link lever drives the stop pawl.

Dans un mode préféré de réalisation, la serrure selon l'invention comporte deux manetons décalés de 180° l'un par rapport à l'autre, les deux manetons se trouvent en saillie sur le disque à manetons de sorte qu'il suffit d'une rotation de 180° au maximum de ce disque pour tirer et débloquer le cliquet d'arrêt. On peut prévoir un interrupteur qui peut être actionné par les manetons du disque à manetons et qui arrête le moteur électrique à chaque fois que le cliquet d'arrêt atteint sa position de déblocage. Avantageusement, le premier levier de liaison est en forme de fourche. Une pièce d'amortissement peut être agencée sur la serrure, le cliquet d'arrêt comportant une butée, de sorte que ledit cliquet d'arrêt est freiné par la pièce d'amortissement lors du mouvement de pivotement provoqué par le ressort du cliquet, de la position de déblocage à la position de blocage. L'engrenage peut être un engrenage à disque sans frein ; le disque à manetons peut être une roue.In a preferred embodiment, the lock according to the invention comprises two crank pins offset by 180 ° relative to each other, the two crank pins are projecting from the crank disc so that it suffices to a maximum rotation of 180 ° of this disc to pull and unlock the stop pawl. A switch can be provided which can be actuated by the crankpins of the crankpin disc and which stops the electric motor each time the stop pawl reaches its unlocked position. Advantageously, the first connecting lever is in the form of a fork. A damping piece can be arranged on the lock, the stop pawl having a stop, so that said stop pawl is braked by the damping piece during the pivoting movement caused by the pawl spring, the unlocked position to the locked position. The gear can be a disc gear without brake; the crankpin disc can be a wheel.

L'invention repose sur l'idée d'utiliser à la place d'un excentrique un disque à manetons avec au moins un maneton agencé sur ce disque, qui coopère, directement ou par l'intermédiaire d'un levier de liaison avec un entraîneur du cliquet d'arrêt. La position du maneton sur le disque à manetons et la longueur de l'entraîneur ou du levier de liaison dans la zone du maneton permet de faire en sorte que le maneton entraîne l'entraîneur ou le levier de liaison seulement jusqu'à ce que la position de déblocage soit atteinte. Une fois que le pêne est débloqué, l'entraîneur ou le levier de liaison a pivoté si loin à cause du maneton que celui-ci passe au-dessus de l'entraîneur ou du levier de liaison et débloque donc le cliquet d'arrêt. Ce cliquet d'arrêt est ensuite ramené par un ressort approprié dans sa position de blocage, de telle sorte que, lorsque l'on ferme la portière, le cliquet d'arrêt peut bloquer le pêne de la façon connue.The invention is based on the idea of using, instead of an eccentric, a crank disc with at least one crank pin arranged on this disc, which cooperates, directly or by means of a linkage lever with a coach. of the stop pawl. The position of crankpin on the crankpin disc and the length of the driver or linkage lever in the crankpin area allows the crankpin to drive the linker or linkage lever only until the unlock position be reached. Once the bolt is released, the driver or link lever has pivoted so far because of the crankpin that it passes over the driver or link lever and thus unlocks the stop pawl. This stop pawl is then returned by a suitable spring to its blocking position, so that, when the door is closed, the stop pawl can block the latch in the known manner.

Pour que le cliquet d'arrêt ne soit pas trop brutalement freiné dans son mouvement vers la position de blocage, il s'est avéré avantageux d'agencer sur la serrure une pièce d'amortissement, par exemple en caoutchouc, par l'intermédiaire de laquelle le cliquet d'arrêt est freiné.So that the stop pawl is not too suddenly braked in its movement towards the blocking position, it has proved advantageous to arrange on the lock a damping piece, for example of rubber, by means of which the stop pawl is braked.

Dans une autre variante de l'invention, on propose d'utiliser comme engrenage un engrenage à vis sans fin, le disque à ergots étant construit comme une roue dentée et correspondant ainsi à une partie de l'engrenage. Une telle disposition offre l'avantage de pouvoir être construite de manière à prendre très peu de place.In another variant of the invention, it is proposed to use a worm gear as a gear, the lug disc being constructed like a toothed wheel and thus corresponding to a part of the gear. Such an arrangement offers the advantage of being able to be constructed so as to take up very little space.

Tandis que le démarrage du moteur électrique est déclenché par un interrupteur agencé sur la poignée de la portière, l'arrêt du moteur s'effectue, de préférence, au moyen d'un interrupteur miniature, qui peut être actionné par le disque à manetons, dès que le cliquet d'arrêt se trouve dans la position de déblocage (et donc dès que le maneton concerné actionnant l'entraîneur ou le levier de liaison est passé par-dessus ces pièces). A l'arrêt du moteur, le disque à manetons est freiné (électriquement) par le moteur.While the start of the electric motor is triggered by a switch arranged on the door handle, the motor is stopped, preferably, by means of a miniature switch, which can be actuated by the crankpin disc, as soon as the stop pawl is in the unlocked position (and therefore as soon as the crankpin concerned actuating the driver or the linkage lever has passed over these parts). When the engine stops, the crank disc is braked (electrically) by the engine.

D'autres particularités et avantages de l'invention se déduisent de l'exemple de réalisation suivant décrit à l'aide du dessin annexé, sur lequel :

  • la figure 1 est une vue de l'arrière de la serrure après avoir retiré le boîtier ;
  • la figure 2 est une coupe selon II-II de la figure 1, le disque à manetons étant dessiné tourné de 90° par rapport à la figure 1 ;
  • la figure 3 est une coupe selon III-III de la figure 2.
Other particularities and advantages of the invention are deduced from the following embodiment described with the aid of the appended drawing, in which:
  • Figure 1 is a view of the rear of the lock after removing the housing;
  • Figure 2 is a section on II-II of Figure 1, the crankpin disc being drawn rotated 90 ° relative to Figure 1;
  • Figure 3 is a section on III-III of Figure 2.

La figure 1 montre une serrure de portière d'automobile désignée par 1 dont le boîtier 2 comporte un creux 3 qui, lorsque la portière de l'automobile est fermée, loge une gâche 4, qui est fixée à la carrosserie de l'automobile. Lors de la fermeture de la portière, la gâche 4 pénètre dans l'encoche 5 d'un pêne 6 qui est agencé de manière à pouvoir tourner autour d'un axe 7 parallèle à la gâche 4. Lorsque la portière de l'automobile est fermée, le pêne est bloqué par un cliquet d'arrêt 8 (figure 3).FIG. 1 shows a door lock for an automobile designated by 1, the housing 2 of which has a recess 3 which, when the door of the automobile is closed, houses a keeper 4, which is fixed to the body of the automobile. When the door is closed, the keeper 4 enters the notch 5 of a bolt 6 which is arranged so as to be able to rotate about an axis 7 parallel to the keeper 4. When the door of the automobile is closed, the bolt is blocked by a stop pawl 8 (Figure 3).

Le boîtier 2 comprend en plus un moteur électrique 9 qui agit par l'intermédiaire d'un engrenage à vis sans fin 10 sur un disque 11 à manetons, qui est une roue tangente et qui est logé de manière à pouvoir tourner autour d'un axe 12. Le disque à manetons 11 comporte deux manetons 13, 14 placés à l'opposé l'un de l'autre, qui, lors de la rotation du disque 11, pénètrent à chaque fois dans un creux d'un premier levier de liaison 15, construit en forme de fourche, et qui font pivoter ce dernier autour d'un axe 16 (figure 2). Un second levier de liaison 17 est également agencé sur l'axe 16, lequel levier de liaison 17 est solidaire en rotation, du premier levier de liaison 15 et se trouve contre un entraîneur 18 solidaire du cliquet d'arrêt 8.The housing 2 further comprises an electric motor 9 which acts by means of a worm gear 10 on a disc 11 with crankpins, which is a tangent wheel and which is housed so as to be able to rotate around a axis 12. The crank pin disc 11 comprises two crank pins 13, 14 placed opposite one another, which, during the rotation of the disc 11, penetrate each time into a hollow of a first lever of link 15, constructed in the form of a fork, and which make the latter pivot about an axis 16 (FIG. 2). A second link lever 17 is also arranged on the axis 16, which link lever 17 is integral in rotation with the first link lever 15 and is located against a driver 18 secured to the stop pawl 8.

Le moteur électrique 9 est relié par l'intermédiaire de conducteurs appropriés à un dispositif de commande (non dessiné), qui est relié quant à lui à des interrupteurs également non dessinés placés sur les poignées de portière ainsi qu'à un interrupteur miniature agencé sur le disque à manetons.The electric motor 9 is connected by means of appropriate conductors to a control device (not shown), which in turn is connected to switches also not drawn, placed on the door handles, as well as to a miniature switch arranged on the crankpin disc.

Lorsque, pour ouvrir une portière d'automobile, on actionne la poignée de ladite portière et donc aussi l'interrupteur miniature associé, le moteur électrique 9 est activé par l'intermédiaire du dispositif de commande. Ce moteur électrique entraîne par l'intermédiaire de l'engrenage à vis sans fin 10 le disque 11. Un des deux manetons 13, 14 pénètre dans le creux 20 de la fourche (figure 1) du premier levier de liaison 15, qui pivote autour de l'axe 16. Avec le premier levier de liaison 15, le second levier de liaison 17 pivote aussi et il appuie contre l'entraîneur 18 du cliquet d'arrêt 8 et fait pivoter celui-ci dans le sens de la flèche 22 (figure 3) en allant à l'encontre de la pression d'un ressort 21 (figure 2). Cette opération se poursuit jusqu'à ce que le pêne 6 ne soit plus bloqué par le cliquet d'arrêt 8 (position de déblocage). Une fois que le blocage par le cliquet d'arrêt 8 est supprimé, la portière de l'automobile s'ouvre par la pression des joints extérieurs de la portière et la gâche 4 est retirée hors du creux 3.When, to open a car door, the handle of said door is actuated and therefore also the associated miniature switch, the electric motor 9 is activated by means of the control device. This electric motor drives via the worm gear 10 the disc 11. One of the two crankpins 13, 14 enters the hollow 20 of the fork (FIG. 1) of the first link lever 15, which pivots around of the axis 16. With the first link lever 15, the second link lever 17 also pivots and it presses against the driver 18 of the stop pawl 8 and makes it pivot in the direction of arrow 22 ( figure 3) going against the pressure of a spring 21 (figure 2). This operation continues until the bolt 6 is no longer blocked by the stop pawl 8 (unlocking position). Once the blocking by the pawl 8 is removed, the door of the automobile opens by the pressure of the exterior seals of the door and the keeper 4 is withdrawn out of the hollow 3.

Comme le disque à manetons 11 continue de tourner, le maneton 13, 14 concerné passe par-dessus l'extrémité 23, située du côté du maneton, du premier levier de liaison 15. Le ressort 21 ramène le cliquet d'arrêt 8 dans la position de blocage en appuyant dessus, un choc trop brutal étant évité au moyen d'une pièce d'amortissement 24. Sensiblement en même temps, l'interrupteur miniature (non dessiné) se trouvant sur le disque 11 est actionné par le second maneton 14, 13 respectivement, le moteur électrique 9 est arrêté par l'intermédiaire du dispositif de commande et le disque 11 est freiné électriquement.As the crankpin disc 11 continues to rotate, the crankpin 13, 14 concerned passes over the end 23, located on the crankpin side, of the first connecting lever 15. The spring 21 brings the stop pawl 8 back into the blocking position by pressing on it, an excessively brutal shock being avoided by means of a damping piece 24. Substantially at the same time, the miniature switch (not shown) located on the disc 11 is actuated by the second crankpin 14 , 13 respectively, the electric motor 9 is stopped by means of the control device and the disc 11 is electrically braked.

L'invention ne se limite naturellement pas à l'exemple de réalisation décrit ci-dessus. Par exemple, il n'est pas obligatoire que l'engrenage soit un engrenage à vis sans fin. Celles des extrémités de l'entraîneur du cliquet d'arrêt ou des leviers de liaison qui sont proches du disque à manetons ne doivent pas obligatoirement être construites en forme de fourches. En outre, le disque à manetons peut aussi comporter un seul maneton ou au contraire plus de deux manetons.The invention is naturally not limited to the embodiment described above. For example, the gear need not be a worm gear. Those of the ends of the ratchet driver or the linkage levers which are close to the crankpin disc need not be constructed in the form of forks. In addition, the crankpin disc may also include a single crankpin or, on the contrary, more than two crankpins.
