- the locking means of the tailgate after its closing consist essentially of a second toothed sector, adjacent and parallel to the first sector, and pivoting with it around a common axis secured to a support plate.
- the motor continues to drive the second sector in rotation, which causes, after appropriate movement transformation, the rectilinear movement of a cable sliding in a sheath.
- the end of the cable rotates a hook-shaped bolt, secured to the boot, to lock a keeper fixed on the tailgate.
- the electric motor can be controlled remotely in the direction appropriate for opening or closing the tailgate either from inside the vehicle or from the outside by means of a boot key.

- FIG. 1 represents the device as a whole, the various driving members of the mechanism being grouped together on a plate 14 fixed inside the boot 3, against the vertical wall 9 of the box located on the right (direction of travel of the vehicle), in the example considered.
- the section in FIG. 1 does not show the presence of a tailgate balancer of any type, for example telescopic, mounted on the left side of the bodywork, the well-known role of which consists in reducing the forces necessary for the operation and to compensate for the weight of the tailgate 1.
- a tailgate balancer of any type, for example telescopic, mounted on the left side of the bodywork, the well-known role of which consists in reducing the forces necessary for the operation and to compensate for the weight of the tailgate 1.
- the plate 14, shown in FIGS. 2 to 4 and in FIG. 6, is mounted on the box 9 by fixing lugs 15 and supports a small electric motor 11 of low power, of the window regulator type, with the pinion output 16 drives two sectors 17, 18 toothed mounted pivoting on the plate about a common axis 19.
- the two sectors 17, 18 are adjacent, parallel to the plate 14 and of the same radius, so that the pinion 16 can drive in rotation simultaneously.
- the curvilinear length of the teeth 20 of the first sector 17, assigned to the operation of the tailgate 1 is less than the curvilinear length of the teeth 21 of the second sector 18, assigned to the locking, so as to cause the locking of the tailgate after closing or vice versa to obtain the opening of the tailgate after unlocking.
- the first sector 17, the furthest from the plate, has a pin 22 guided in a first curvilinear lumen 23 of the plate after having crossed the second sector 18 interposed between the first sector 17 and the plate 14.
- the second sector 18 itself has a curvilinear lumen 24 superimposable on the first lumen 23 of the plate but of shorter length.
- the second sector 18 also has a pin 25 guided through a second curvilinear lumen 26 of the plate, parallel to the first lumen 23 and of length suitable for the operation of the locking mechanism which will be described below.
- toothed sector 17 assigned to the anchor, is extended on a straight side by an arm 27, the end of which supports a ball joint 28 for the articulation of the tie rod 12 as shown in FIG. 5.
- the locking of the tailgate 1 is obtained by means of a transformation then of a movement transmission from the plate 14 to the latch 13.
- the lower part of the plate forms an elbow 29 (FIG. 7) supporting a sheath 30 in which a transmission cable 31 slides.
- the lower elbow 29 of the plate is pierced with a longitudinal slot 32 crossed by a fork 33 with two branches, integral with the cable 31, and therefore capable of moving with it over the stroke determined by the length of the slot 32 ( Figure 6) .
- the relative positions of the slot 32 and the second curvilinear light 26 of the plate as well as the trajectories of the fork 33 and the pin 25 of the locking sector are such that the fork can be moved by the pin engaging between the branches of the fork, which ensures the transformation of circular / rectilinear movement or vice versa, according to the directions of rotation of the motor 11.
- the branches of the fork 33 are moreover unequal lengths ( Figure 2).
- the rectilinear movement is used to actuate the lock 13 from a distance, consisting of a bolt 34 in the form of a hook, the pivoting of which locks a keeper 35.
- the keeper fixed element of the lock, is a simple buttonhole mounted on the lower part of the tailgate 1.
- the bolt 34 is articulated on a support 36 itself fixed on the lining of the rear skirt 8 of the bodywork.
- the nose of the hook 34 in cam profile, engages in the keeper 35 to lock the tailgate on the boot box.
- the hook is, moreover, returned to the unlocking position by a spiral spring 37 wound around the hinge pin 38 of the hook.
- This tab slides outside the sheath 30 in the same manner as the fork 33 previously described.
- the electrical control of the engine 11 can be shown diagrammatically by the circuit of FIG. 11. It simply shows that the engine can be triggered in the desired direction either by a switch 41 located in the passenger compartment, for example on the dashboard, or by an external switch 42 operated with a key 43 and mounted on the rear skirt 8 of the body ( Figures 1 and 8).
- a switch 44 located in the trunk and disposed on the control circuit from the passenger compartment, makes it possible to neutralize this last command 41 so as to keep only the external control 42.
- This provision optional, makes it possible to avoid access to the boot 3 by the simple violation of the passenger compartment 5.
- the deletion of the command from the passenger compartment 41 is of no consequence for all cases where the user is in any case obliged to move to intervene himself in the boot 3.
- the output pinion 16 After controlling the geared motor 11 in the appropriate direction by one of the switches, described above, the output pinion 16 simultaneously meshes the two toothed sectors to rotate them to the position in FIG. 3 which corresponds to the closed tailgate, resting on its seal and driven by the articulated tie rod 12 on the operating sector 17.
- the pins 22, 25 of the two sectors move in their respective light of the plate while maintaining their relative angular deviation, compared to that of FIG. 2.
- the operating sector 17 comes to a standstill as soon as the pinion 16 reaches the toothing interruption 45 separating said toothing 20 from the articulation arm 27.
- the travel of the first sector 17 corresponds substantially to the length of the first curvilinear lumen 23 of the plate, while the pin 25 of the second sector (locking) engages between the branches of the fork 33 placed on the path of the second curvilinear light of the plate.
- This position of the fork corresponds to the unlocking of the keeper 35, represented in FIG. 9, position maintained by the return spring 37 of the bolt.
- the pinion 16 of the motor continues its rotation and continues the pivoting of the second sector 18 through its teeth 21 until it reaches the locking position of FIG. 4.
- the light 24 of the second sector allows the latter to pivot over the entire stroke corresponding to the locking, despite the immobilization of the pin 22 of the first sector, while the pin 25 of the second sector 18 displaces the fork 33 and therefore the transmission cable 31 to rotate the hook 34 at a distance by constraining its spring 37 and thus bringing it into the locked position of FIG. 10.
- the locking and then opening of the tailgate 1 reproduces the reverse stages of the operation of the mechanism after reversing the direction of rotation of the pinion 16.
- the toothing 20 of the operating sector 17 is facilitated by the locking sector 17 whose curvilinear light 24 drives the pin 22 of the first sector being in abutment.
- the invention is not limited to the example of embodiment described, but includes simple technical equivalents.

Description
L'invention concerne un dispositif de manoeuvre et de verrouillage automatiques à distance d'une porte de coffre ou du hayon d'un véhicule automobile.The invention relates to a device for automatically operating and locking a remote trunk door or the tailgate of a motor vehicle.
Le brevet américain 3 713 472 décrit un dispositif de manoeuvre d'un hayon qui utilise un moteur d'entraînement d'une roue dentée qui assure conjointement le mouvement du hayon et la commande de la serrure de verrouillage ou de déverrouillage. A cet effet la roue dentée actionne conjointement le déplacement les leviers et bras de maintien du hayon et la commande de la serrure au moyen d'un cable souple.The US patent 3,713,472 describes a device for operating a tailgate which uses a drive motor of a toothed wheel which jointly ensures the movement of the tailgate and the control of the locking or unlocking lock. For this purpose the toothed wheel jointly actuates the movement of the levers and arms for holding the tailgate and the control of the lock by means of a flexible cable.
L'invention propose un dispositif de manoeuvre et de verrouillage dans lequel le processus de verrouillage et de déverrouillage est dissocié du mouvement du hayon, dans le but de libérer ce dernier de tout effort lors de l'action du verrou.The invention provides an operating and locking device in which the locking and unlocking process is dissociated from the movement of the tailgate, with the aim of releasing the latter from any effort during the action of the lock.
Il est en effet intéressant de centraliser les efforts de commande d'ouverture ou de fermeture du hayon sur le mécanisme de verrouillage et de déverrouillage lorsque l'on actionne celui-ci dans le but de le préserver des contraintes parasites susceptibles d'affecter son bon fonctionnement.It is in fact advantageous to centralize the efforts to control the opening or closing of the tailgate on the locking and unlocking mechanism when the latter is actuated in order to preserve it from parasitic stresses liable to affect its good operation.
A cet effet, l'invention a pour objet un dispositif de manoeuvre et de verrouillage automatiques d'un hayon de véhicule automobile articulé à la partie supérieure de la carrosserie actionné au moyen d'un moteur électrique monté sur une platine à l'intérieur du coffre et commandé à distance afin d'assurer d'une part l'ouverture et la fermeture du hayon par l'intermédiaire d'un pignon engrênant avec une denture portée par un élément agissant sur des moyens de liaison mécaniques articulés entre le hayon et l'élément et d'autre part le verrouillage et le déverrouillage de la serrure du hayon par rapport à la partie fixe arrière de la carrosserie, caractérisé en ce qu'il comprend deux secteurs dentés adjacents et de même rayon, montés pivotants autour d'un axe commun solidaire de la platine et pouvant être entraînés successivement par le pignon de sortie du moteur, en ce que la platine comporte deux lumières curvilignes parallèles, décalées angulairement et de longueurs inégales, en ce que le premier secteur, relié au hayon par l'intermédiaire d'un tirant articulé, comporte un pion traversant à la fois la lumière curviligne de la platine et une autre lumière curviligne pratiquée dans le secteur et superposable à la lumière, en ce que le second secteur, affecté au verrouillage du hayon qui suit sa fermeture, comporte un pion traversant la lumière de la platine et interceptant une fourchette fixée sur un câble commandant la serrure du hayon et en ce que la denture du premier secteur est munie d'une interruption de denture pratiquée à la périphérie dit secteur, une extrémité de la lumière curviligne du second secteur venant en prise avec le pion du premier secteur entraînant ce dernier et assurant ainsi la reprise avec le pignon de la denture, l'autre extrémité de la lumière étant disposée à une distance telle de la première extrémité que le second secteur puisse encore tourner après immobilisation du premier secteur permettant ainsi respectivement un déverrouillage ou verrouillage de la serrure du hayon au repos de ce dernier.To this end, the subject of the invention is an automatic maneuvering and locking device for a tailgate of a motor vehicle articulated at the upper part of the body, actuated by means of an electric motor mounted on a plate inside the safe and remotely controlled to ensure on the one hand the opening and closing of the tailgate by means of a pinion meshing with a toothing carried by an element acting on mechanical connecting means articulated between the tailgate and the element and on the other hand the locking and unlocking of the tailgate lock with respect to the rear fixed part of the bodywork, characterized in that it comprises two adjacent toothed sectors and of the same radius, pivotally mounted around a common axis integral with the plate and being able to be successively driven by the output pinion of the motor, in that the plate comprises two parallel curvilinear slots, angularly offset and of unequal lengths, in that the first sector, connected to the tailgate by means of an articulated tie rod, comprises a pin passing through both the curvilinear light of the plate and another curvilinear light practiced in the sector and superimposable on the light, in that the second sector, assigned to the locking of the tailgate which follows its closure, comprises a pin passing through the light of the plate and intercepting a fork fixed on a cable controlling the lock of the tailgate and in that the teeth of the first sector are provided with an interruption of toothing practiced at the periphery said sector, one end of the curvilinear lumen of the second sector engaging the pin of the first sector driving the latter and thus ensuring the resumption with the pinion of the toothing, the other end of the light being disposed at such a distance from the first end that the second sector can still rotate after immobilization of the first sector thus allowing respectively unlocking or locking tooling of the tailgate lock at rest of the latter.
Les moyens de verrouillage du hayon après sa fermeture sont constitués essentiellement d'un deuxième secteur denté, adjacent et parallèle au premier secteur, et pivotant avec lui autour d'un axe commun solidaire d'une platine-support. Après l'immobilisation du premier secteur, le moteur poursuit l'entraînement en rotation du deuxième secteur, ce qui provoque, après transformation de mouvement appropriée, le déplacement rectiligne d'un câble coulissant dans une gaine. L'extrémité du câble fait pivoter un pêne en forme de crochet, solidaire du coffre, pour verrouiller une gâche fixée sur le hayon.The locking means of the tailgate after its closing consist essentially of a second toothed sector, adjacent and parallel to the first sector, and pivoting with it around a common axis secured to a support plate. After immobilization of the first sector, the motor continues to drive the second sector in rotation, which causes, after appropriate movement transformation, the rectilinear movement of a cable sliding in a sheath. The end of the cable rotates a hook-shaped bolt, secured to the boot, to lock a keeper fixed on the tailgate.
Le moteur électrique peut être commandé à distance dans le sens approprié à l'ouverture ou à la fermeture du hayon soit de l'intérieur du véhicule, soit de l'extérieur au moyen d'une clef de coffre. Un interrupteur supplémentaire, disposé dans le coffre, permet de neutraliser la commande intérieure de manière à pouvoir, à la demande, continuer à isoler le verrouillage du coffre de celui des portes latérales, mesure de sécurité antivol exploitée sur la plupart des véhicules.The electric motor can be controlled remotely in the direction appropriate for opening or closing the tailgate either from inside the vehicle or from the outside by means of a boot key. An additional switch, located in the boot, enables the interior control to be deactivated so that, on request, it can continue to isolate the boot lock from that of the side doors, an anti-theft security measure used on most vehicles.
Le mécanisme de manoeuvre du hayon par tirant articulé est monté sur un côté du véhicule, l'autre côté conservant un équilibreur de type classique, par exemple télescopique. Cependant, la compensation exercée par l'équilibreur restant permet de limiter notablement la puissance requise du moteur. Pratiquement, un moteur de lèvevitres s'avère suffisant pour actionner le câble de verrouillage et provoquer la levée du hayon par le pivotement des secteurs dentés.The mechanism for operating the tailgate by an articulated tie rod is mounted on one side of the vehicle, the other side retaining a balancer of the conventional type, for example telescopic. However, the compensation exerted by the remaining balancer makes it possible to significantly limit the required power of the engine. In practice, a window regulator motor is sufficient to activate the locking cable and cause the liftgate to be lifted by the pivoting of the toothed sectors.

En se reportant à la figure 1, on reconnaît, en coupe, l'arrière d'un véhicule automobile équipé d'un hayon 1 pivotant à la partie supérieure de la carrosserie autour d'un axe transversal 2. Le coffre à bagages 3 est délimité successivement par le hayon 1 lui-même, la tablette horizontale 4 de séparation entre le coffre 3 et l'habitacle 5, la face arrière des dossiers de sièges arrière 6, le plancher inférieur 7 et le caisson du coffre formé par la jupe arrière 8 et les parois latérales 9 de la carrosserie (figure 6).Referring to Figure 1, we recognize, in section, the rear of a motor vehicle equipped with a
Conformément à l'invention, le hayon 1 peut être manoeuvré et verrouillé automatiquement au moyen d'un mécanisme 10 à secteurs dentés actionnés par un moteur électrique 11 et agissant successivent sur un tirant 12 articulé entre le hayon et l'un des secteurs dentés et sur un verrou 13 verrouillant le hayon 1 sur le caisson 8, 9 du coffre.According to the invention, the
La figure 1 représente le dispositif dans son ensemble, les divers organes moteurs du mécanisme étant regroupés sur une platine 14 fixée à l'intérieur du coffre 3, contre la paroi verticale 9 du caisson située à droite (sens de la marche du véhicule), dans l'exemple considéré.FIG. 1 represents the device as a whole, the various driving members of the mechanism being grouped together on a
La coupe de la figure 1 ne permet pas de voir la présence d'un équilibreur de hayon de type quelconque, par exemple télescopique, monté sur le côté gauche de la carrosserie dont le rôle bien connu consiste à réduire les efforts nécessaires à la manoeuvre et à compenser le poids du hayon 1.The section in FIG. 1 does not show the presence of a tailgate balancer of any type, for example telescopic, mounted on the left side of the bodywork, the well-known role of which consists in reducing the forces necessary for the operation and to compensate for the weight of the
La platine 14, représentée sur les figures 2 à 4 et sur la figure 6, est montée sur le caisson 9 par des pattes de fixation 15 et supporte un petit moteur électrique 11 de faible puissance, type motoréducteur de lève-vitres, dont le pignon de sortie 16 entraîne deux secteurs 17, 18 dentés montés pivotant sur la platine autour d'un axe commun 19. Les deux secteurs 17, 18 sont adjacents, parallèles à la platine 14 et de même rayon, si bien que le pignon 16 peut les entraîner en rotation simultanément.The
Cependant, la longueur curviligne de la denture 20 du premier secteur 17, affecté à la manoeuvre du hayon 1, est inférieure à la longueur curviligne de la denture 21 du deuxième secteur 18, affecté au verrouillage, de manière à provoquer le verrouillage du hayon après sa fermeture ou inversement pour obtenir l'ouverture du hayon après son déverrouillage.However, the curvilinear length of the
Le premier secteur 17, le plus éloigné de la platine, possède un pion 22 guidé dans une première lumière curviligne 23 de la platine après avoir traversé le deuxième secteur 18 interposé entre le premier secteur 17 et la platine 14. Afin de pouvoir se débattre relativement au premier secteur, le deuxième secteur 18 possède lui-même une lumière curviligne 24 superposable à la première lumière 23 de la platine mais de longueur plus courte. En outre, le deuxième secteur 18 possède également un pion 25 guidé à travers une seconde lumière curviligne 26 de la platine, parallèle à la première lumière 23 et de longueur adaptée au fonctionnement du verrouillage qui sera décrit ci-après.The
Enfin, le secteur denté 17, affecté à la manceu- vre, est prolongé sur un côté rectiligne par un bras 27 dont l'extrémité supporte une rotule 28 pour l'articulation du tirant 12 ainsi que le représente la figure 5.Finally, the
Le verrouillage du hayon 1 est obtenu par l'intermédiaire d'une transformation puis d'une transmission de mouvement depuis la platine 14 jusqu'au verrou 13.The locking of the
A cet effet, la partie inférieure de la platine forme un coude 29 (figure 7) supportant une gaine 30 dans laquelle coulisse un câble de transmission 31.To this end, the lower part of the plate forms an elbow 29 (FIG. 7) supporting a
Par ailleurs, le coude inférieur 29 de la platine est percé d'une fente longitudinale 32 traversée par une fourchette 33 à deux branches, solidaire du câble 31, et donc susceptible de se déplacer avec lui sur la course déterminée par la longueur de la fente 32 (figure 6).Les positions relatives de la fente 32 et de la deuxième lumière curviligne 26 de la platine ainsi que les trajectoires de la fourchette 33 et du pion 25 du secteur de verrouillage sont telles que la fourchette peut être déplacée par le pion s'engageant entre les branches de la fourchette, ce qui assure la transformation de mouvement circulaire/rectiligne ou inversement, selon les sens de rotation du moteur 11.Furthermore, the
Pour permettre l'engagement ou le dégagement du pion, les branches de la fourchette 33 sont d'ailleurs de longuéurs inégales (figure 2). A l'autre extrémité du câble 31 (figures 8 à 10), le mouvement rectiligne est exploité pour actionner à distance le verrou 13 composé d'un pêne 34 en forme de crochet dont le pivotement vient verrouiller une gâche 35.To allow engagement or disengagement of the pin, the branches of the
La gâche, élément fixe du verrou, est une simple boutonnière montée sur la partie inférieure du hayon 1. Le pêne 34 est articulé sur un support 36 lui-même fixé sur le doublage de la jupe arrière 8 de la carrosserie. Le nez du crochet 34, en profil de came, s'engage dans la gâche 35 pour verrouiller le hayon sur le caisson du coffre. Le crochet est, en outre, rappelé en position de déverrouillage par un ressort spiral 37 enroulé autour de l'axe d'articulation 38 du crochet.The keeper, fixed element of the lock, is a simple buttonhole mounted on the lower part of the
La transformation de mouvement rectiligne/cir- culaire est obtenue au moyen d'une biellette 39 articulée entrle le crochet 34 et une patte 40 solidaire de l'extrémité du câble 31.The transformation of rectilinear / circular movement is obtained by means of a
Cette patte coulisse à l'extérieur de la gaine 30 de la même manière que la fourchette 33 précédemment décrite.This tab slides outside the
A titre d'exemple, la commande électrique du moteur 11 peut être schématisée par le circuit de la figure 11. Il montre simplement que le moteur peut être déclenché dans le sens désiré soit par un interrupteur 41 situé dans l'habitacle, par exemple sur le tableau de bord, ou bien par un interrupteur extérieur 42 manoeuvré à l'aide d'une clef 43 et monté sur la jupe arrière 8 de la carrosserie (figures 1 et 8).By way of example, the electrical control of the
De plus, un interrupteur 44, situé dans le coffre et disposé sur le circuit de commande depuis l'habitacle, permet de neutraliser cette dernière commande 41 pour ne conserver que la commande extérieure 42. Cette disposition, facultative, permet d'éviter l'accès au coffre 3 par la simple violation de l'habitacle 5. Par ailleurs, la suppression de la commande depuis l'habitacle 41 est sans conséquence pour tous les cas où l'utilisateur est de toute façon obligé de se déplacer pour intervenir lui-même dans le coffre 3.In addition, a
Le dispositif selon l'invention fonctionne comme suit:
- Nous partons de la position ouverte du hayon 1 (figure 2) pour laquelle les deux secteurs dentés 17, 18 se trouvent en position haute, en butée sur l'extrémité de la
première limière 23 de la platine, par lepion 22 du premier secteur qui traverse successivement ledeuxième secteur 18 puis la platine 14 (figure 6).
- We start from the open position of the tailgate 1 (Figure 2) for which the two
17, 18 are in the high position, in abutment on the end of thetoothed sectors first bloodhole 23 of the plate, by thepin 22 of the first sector which successively crosses thesecond sector 18 then the plate 14 (Figure 6).
Après avoir commandé le motoréducteur 11 dans le sens approprié par l'un des interrupteurs, décrits précédemment, le pignon de sortie 16 engrène simultanément les deux secteurs dentés pour les faire pivoter jusqu'à la position de la figure 3 qui correspond au hayon fermé, en appui sur son joint d'étanchéité et entraîné par l'intermédiaire du tirant articulé 12 sur le secteur de manoeuvre 17.After controlling the geared
Simultanément, les pions 22, 25 des deux secteurs de déplacent dans leur lumière respective de la platine en conservant leur écart angulaire relatif, par rapport à celui de la figure 2.Simultaneously, the
Le secteur de manoeuvre 17 s'immobilise dès que le pignon 16 atteint l'interruption de denture 45 séparant ladite denture 20 du bras d'articulation 27. La course du premier secteur 17 correspond sensiblement à la longueur de la première lumière curviligne 23 de la platine, tandis que le pion 25 du deuxième secteur (de verrouillage) s'engage entre les branches de la fourchette 33 placée sur la trajectoire de la deuxième lumière curviligne de la platine. Cette position de la fourchette correspond au déverrouillage de la gâche 35, représenté sur la figure 9, position maintenue par le ressort de rappel 37 du pêne.The
Le pignon 16 du moteur continue sa rotation et poursuit le pivotement du deuxième secteur 18 par sa denture 21 jusqu'à ce qu'il atteigne la position de verrouillage de la figure 4.The
La lumière 24 du deuxème secteur permet à ce dernier de pivoter sur toute la course correspondant au verrouillage, malgré l'immobilisation du pion 22 du premier secteur, tandis que le pion 25 du deuxième secteur 18 déplace la fourchette 33 et donc le câble de transmission 31 pour faire pivoter le crochet 34 à distance en contraignant son ressort 37 et l'amener ainsi dans la position verrouillée de la figure 10.The light 24 of the second sector allows the latter to pivot over the entire stroke corresponding to the locking, despite the immobilization of the
Le verrouillage puis l'ouverture du hayon 1 reproduisent les étapes inverses du fonctionnement du mécanisme après inversion du sens de rotation du pignon 16. Après le déverrouillage du hayon (figure 3), la reprise de denture 20 du secteur de manoeuvre 17 est facilitée par le secteur de verrouillage 17 dont la lumière curviligne 24 entraîne le pion 22 du premier secteur se trouvant en butée.The locking and then opening of the
L'invention n'est pas limitée à l'exemple de réalisation décrit mais englobe les équivalents techniques simples.The invention is not limited to the example of embodiment described, but includes simple technical equivalents.
C'est ainsi que les transformations de mouvements successives pourraient être obtenues par courroies ou tringleries au lieu de câble 31 et de biellette 39 ou que les commandes électriques peuvent être multipliées, placées différemment et faire appel à des circuits plus sophistiqués tels que des commandes par impulsions et des inverseurs de marche électroniques.Thus the transformations of successive movements could be obtained by belts or linkages instead of
