Description

MÉCANISME D'ENTRAÎNEMENT D'UN OUVRANT DE VÉHICULE  DRIVE MECHANISM OF A VEHICLE OPENING
Domaine de l'invention Field of the invention
L'invention relève des mécanismes d'ouverture et de fermeture d'un ouvrant de véhicule, et concerne plus particulièrement un mécanisme d'entraînement d'un ouvrant de véhicule automobile.  The invention relates to the opening and closing mechanisms of a vehicle door, and more particularly relates to a drive mechanism of a motor vehicle door.
État de l'art State of the art
Dans le présent texte, le terme « ouvrant » fait référence à un élément du véhicule, mobile entre une position d'ouverture et une position de fermeture d'une baie d'un véhicule, dans lesquelles il autorise ou non l'accès à l'intérieur du véhicule.  In this text, the term "opening" refers to an element of the vehicle, movable between an open position and a closed position of a bay of a vehicle, in which it authorizes or not access to the vehicle. inside the vehicle.
Plus particulièrement, dans le présent texte, le terme « ouvrant » désigne les portes latérales d'un véhicule automobile permettant l'accès à l'habitacle de celui-ci, c'est-à-dire à l'intérieur du véhicule. Ces portes sont composées d'un panneau de structure solidaire du châssis du véhicule par le biais d'un mécanisme d'articulation généralement formé par une charnière permettant au panneau de structure de la porte de pouvoir pivoter autour d'un axe. Il existe plusieurs types de portes de véhicules automobiles permettant à un utilisateur de pouvoir entrer ou sortir de son véhicule. Ces différents types de portes sont caractérisés par leur cinématique d'entraînement leur permettant d'évoluer entre une position d'ouverture d'une baie du véhicule, dans laquelle un utilisateur à accès à l'habitacle du véhicule, et une position de fermeture d'une baie du véhicule, dans laquelle la porte interdit l'accès à l'habitacle du véhicule.  More particularly, in the present text, the term "opening" means the side doors of a motor vehicle allowing access to the passenger compartment thereof, that is to say inside the vehicle. These doors are composed of a structural panel integral with the vehicle frame by means of a hinge mechanism generally formed by a hinge allowing the door structure panel to be able to pivot about an axis. There are several types of motor vehicle doors allowing a user to enter or exit his vehicle. These different types of doors are characterized by their drive kinematics allowing them to evolve between an open position of a vehicle bay, in which a user has access to the passenger compartment of the vehicle, and a closed position of the vehicle. a bay of the vehicle, in which the door prohibits access to the passenger compartment of the vehicle.
Dans le domaine automobile, il est très courant qu'un véhicule comprenne une ou deux portes latérales articulées à chacun des flancs dudit véhicule par une ou deux charnières à axe de rotation sensiblement vertical.  In the automotive field, it is very common for a vehicle to comprise one or two lateral doors articulated to each of the sides of said vehicle by one or two hinges with a substantially vertical axis of rotation.
Dans ce domaine, on connaît également notamment les portes à levée verticale destinées à être élevée au dessus du véhicule lorsqu'elle occupe la position d'ouverture. Parmi ces portes à levée verticale, il existe les portes du type « élytre » destinées à pivoter autour d'un axe sensiblement horizontal plus ou moins orthogonal au sens d'avance du véhicule. Il existe également les portes à levée verticale du type « papillon » destinées à pivoter autour d'un axe sensiblement horizontal parallèle au sens d'avance du véhicule. In this field, we also know in particular vertical lift doors intended to be raised above the vehicle when it occupies the open position. Among these vertical lift doors, there are the doors of the "elytron" type for pivoting about a substantially horizontal axis more or less orthogonal to the direction of advance of the vehicle. There are also "Butterfly" type vertical lift doors for pivoting about a substantially horizontal axis parallel to the direction of travel of the vehicle.
Ces différents types de porte à levée verticale présentent tous des inconvénients. Notamment, les portes du type « élytre », lorsqu'elles sont en position d'ouverture de la baie du véhicule, de dégagent pas complètement la baie, de sorte qu'elles n'offrent qu'un accès restreint à l'intérieur ou à l'extérieur du véhicule.  These different types of vertical lift door all have disadvantages. In particular, the doors of the "elytron" type, when they are in the open position of the vehicle bay, do not completely clear the bay, so that they offer only restricted access to the interior or outside the vehicle.
En outre, afin d'éviter d'évidents problèmes d'encombrement lors de l'ouverture et de la fermeture des portes, la charnière permettant l'articulation des portes du type « papillon » est généralement disposée dans un renfoncement latéral pratiqué sur le toit du châssis, à distance des flancs du véhicule. Le panneau de structure d'une porte de type « papillon » comprend donc généralement une portion pliée formant des éléments de carrosserie du toit.  In addition, in order to avoid obvious congestion problems when opening and closing the doors, the hinge allowing the articulation of the "butterfly" type doors is generally arranged in a lateral recess made on the roof of the chassis, away from the sides of the vehicle. The structural panel of a "butterfly" type door therefore generally comprises a folded portion forming roof body elements.
Les renfoncements latéraux du toit du châssis génèrent une faiblesse structurelle du châssis aux efforts mécaniques. De ce fait, des éléments raidisseurs sont intégrés au châssis afin de lui apporter la résistance mécanique nécessaire pour supporter les contraintes notamment générées par le poids des portes et par les efforts subis par le châssis lorsque le véhicule automobile est en déplacement.  The lateral recesses of the roof of the chassis generate a structural weakness of the chassis to the mechanical forces. As a result, stiffening elements are integrated into the chassis in order to provide it with the mechanical strength necessary to withstand the particular stresses generated by the weight of the doors and by the forces experienced by the chassis when the motor vehicle is in motion.
Il résulte de ces dispositions un surpoids non négligeable pour les véhicules dotés des portes de type à levée verticale, notamment celles du type « papillon », par rapport aux véhicules comprenant des portes d'autres types, ainsi qu'un surcoût substantiel.  The result of these provisions is a significant overweight for vehicles with vertical lift type doors, including those of the "butterfly" type, compared to vehicles with doors of other types, and a substantial additional cost.
Un autre inconvénient réside dans l'allongement du temps de fabrication d'un véhicule comprenant des portes à levée verticale du fait des arrangements particuliers du châssis du véhicule.  Another disadvantage lies in the lengthening of the manufacturing time of a vehicle comprising vertical lift doors due to particular arrangements of the vehicle chassis.

La présente invention a pour objectif de palier les inconvénients précités en proposant un mécanisme d'entraînement d'un ouvrant de véhicule permettant une levée verticale de l'ouvrant par rapport au véhicule et n'entraînant pas de surpoids dudit véhicule. Un autre objectif de la présente invention est de proposer un mécanisme d'entraînement de conception simple et peu onéreux, qui permet de conserver un faible encombrement latéral lors de l'entraînement de l'ouvrant. The present invention aims to overcome the aforementioned drawbacks by providing a drive mechanism of a vehicle opening allowing a vertical lift of the opening relative to the vehicle and not causing overweight of said vehicle. Another object of the present invention is to provide a drive mechanism of simple design and inexpensive, which allows to keep a small lateral space during the drive of the opening.
Un objectif supplémentaire de la présente invention est de faire en sorte que l'ouvrant dégage complètement la baie d'un véhicule lorsqu'il est en position d'ouverture afin de faciliter l'accès à l'intérieur ou à l'extérieur du véhicule.  An additional object of the present invention is to ensure that the opening completely clears the bay of a vehicle when it is in the open position to facilitate access to the inside or outside of the vehicle .
A cet effet, la présente invention concerne un mécanisme d'entraînement d'un ouvrant de véhicule comprenant un panneau de structure. Le mécanisme d'entraînement comprend :  For this purpose, the present invention relates to a drive mechanism of a vehicle opening comprising a structural panel. The drive mechanism comprises:
- une bielle s'étendant entre deux extrémités dont une première extrémité est configuré pour être solidaire d'un pied milieu d'un châssis du véhicule par le biais d'une articulation dite « première articulation » agencée de manière adjacente au toit du châssis, et dont une seconde extrémité est configuré pour être solidaire du panneau de structure de l'ouvrant de véhicule, et  a connecting rod extending between two ends of which a first end is configured to be secured to a central pillar of a chassis of the vehicle by means of a so-called "first articulation" joint arranged adjacent to the roof of the chassis, and a second end of which is configured to be integral with the structure panel of the vehicle door, and
- au moins un vérin étant, d'une part, solidaire de la bielle, entre ses deux extrémités, et étant d'autre part, configuré pour être solidaire du pied milieu d'un châssis du véhicule, par l'intermédiaire d'une articulation dite « seconde articulation » agencée de manière adjacente au plancher du châssis, ledit vérin étant adapté à réaliser un mouvement de translation provoquant le déplacement de l'ouvrant entre une position de fermeture et une position d'ouverture d'une baie du véhicule.  at least one jack being, on the one hand, integral with the connecting rod, between its two ends, and being on the other hand, configured to be integral with the central pillar of a chassis of the vehicle, by means of a so-called "second articulation" articulation arranged adjacent to the floor of the chassis, said cylinder being adapted to perform a translational movement causing the movement of the opening between a closed position and an open position of a vehicle bay.
Le mécanisme d'entraînement comprend un faible nombre d'éléments mobiles, et présente, par conséquent, une fiabilité importante et un coût réduit.  The drive mechanism comprises a small number of moving elements, and therefore has a high reliability and a reduced cost.
En outre, grâce à ces dispositions, le mécanisme d'entraînement permet une levée verticale de l'ouvrant sans nécessiter de renfoncement dans le toit du châssis du véhicule. La rigidité du châssis est donc préservée du fait qu'aucun aménagement du toit du châssis, susceptible de modifier ses caractéristiques mécaniques, n'est nécessaire. Le mécanisme d'entraînement d'ouvrant de véhicule selon l'invention permet donc de pouvoir installer des portes de type à levée verticale sur des véhicules dont le toit présente des aménagements particuliers tels que des toits ouvrants ou toits panoramiques. In addition, thanks to these provisions, the drive mechanism allows a vertical lift of the opening without requiring recess in the roof of the vehicle chassis. The rigidity of the chassis is thus preserved because no development of the roof of the chassis, likely to modify its mechanical characteristics, is necessary. The vehicle opening drive mechanism according to the invention therefore makes it possible to install Vertical lift type doors on vehicles whose roof has special features such as sunroofs or panoramic roofs.
Dans le présent texte, lorsqu'on parle de deux pièces « solidaires » l'une à l'autre, on entend qu'elles présentent une liaison mécanique l'une à l'autre comprenant au moins un degré de liberté en rotation.  In the present text, when we speak of two pieces "solidary" to one another, it is understood that they have a mechanical connection to each other comprising at least one degree of freedom in rotation.
Préférentiellement, le mécanisme d'entraînement comprend seulement une bielle et au moins un vérin, par exemple deux, de sorte que ledit mécanisme soit simple de conception et présente une grande fiabilité. En outre, la fabrication et l'intégration d'un tel mécanisme sur un véhicule, par exemple lors d'une étape de fabrication d'une automobile sur une ligne de production, présente l'avantage d'être rapide et ainsi peu onéreux.  Preferably, the drive mechanism comprises only a connecting rod and at least one jack, for example two, so that said mechanism is simple in design and has high reliability. In addition, the manufacture and integration of such a mechanism on a vehicle, for example during a step of manufacturing a car on a production line, has the advantage of being fast and thus inexpensive.
Pour rappel, le pied milieu d'un châssis d'un véhicule automobile est un montant latéral vertical reliant le plancher du châssis au toit du châssis. Lorsque le véhicule comprend des places avant et arrière, le pied milieu est généralement disposé de sorte à séparer l'ouverture d'accès aux places avant de l'ouverture d'accès aux places arrière.  As a reminder, the middle foot of a chassis of a motor vehicle is a vertical side upright connecting the chassis floor to the roof of the chassis. When the vehicle comprises front and rear seats, the center pillar is generally arranged to separate the access opening to the front seats of the access opening to the rear seats.
Le mécanisme d'entraînement selon l'invention est préférentiellement destiné à entraîner un ouvrant de véhicule formant un unique ensemble mobile permettant l'accès simultanément aux places avant et arrière du véhicule.  The drive mechanism according to the invention is preferably intended to drive a vehicle opening forming a single mobile assembly allowing access simultaneously to the front and rear seats of the vehicle.
II y a lieu de noter que dans le présent texte, lorsque l'on parle du châssis du véhicule, on parle d'un châssis du type châssis-coque tel que généralement utilisé dans le domaine automobile pour les véhicules produits en série, et à la portée de l'homme du métier.  It should be noted that in the present text, when we speak of the chassis of the vehicle, we speak of a chassis-hull type chassis as generally used in the automotive field for mass-produced vehicles, and to the scope of the skilled person.
L'au moins un vérin est solidaire du pied milieu de manière adjacente au plancher du châssis, de sorte à maximiser la course des tiges de vérins.  The at least one jack is integral with the central pillar adjacent to the floor of the frame, so as to maximize the stroke of the cylinder rods.
Un autre avantage de ces caractéristiques réside dans le fait que le mécanisme d'entraînement occupe un volume relativement faible, lorsque l'ouvrant occupe la position d'ouverture ou la position de fermeture d'une baie du véhicule. Notamment, lorsque l'ouvrant occupe la position d'ouverture de la baie du véhicule, un espace de circulation attenant au véhicule est aménagé. Plus particulièrement, le mécanisme d'entraînement est avantageusement dimensionné de sorte qu'un utilisateur puisse se tenir debout sous l'ouvrant lorsqu'il est en position d'ouverture. Dans des modes particuliers de réalisation, l'invention répond en outre aux caractéristiques suivantes, mises en œuvre séparément ou en chacune de leurs combinaisons techniquement opérantes. Another advantage of these features lies in the fact that the drive mechanism occupies a relatively small volume, when the opening is in the open position or the closed position of a vehicle bay. In particular, when the opening occupies the opening position of the vehicle bay, a traffic space adjacent to the vehicle is arranged. More particularly, the drive mechanism is advantageously dimensioned so that a user can stand under the sash when it is in the open position. In particular embodiments, the invention also fulfills the following characteristics, implemented separately or in each of their technically operating combinations.
Dans des modes particuliers de réalisation de l'invention, une butée est adaptée à limiter le débattement angulaire du panneau par rapport à la bielle lors du déplacement de l'ouvrant vers la position d'ouverture d'une baie du véhicule de sorte que lorsque l'ouvrant est en position d'ouverture, le panneau de structure est inscrit dans un plan sensiblement horizontal.  In particular embodiments of the invention, an abutment is adapted to limit the angular movement of the panel relative to the connecting rod during movement of the opening to the open position of a vehicle bay so that when the opening is in the open position, the structural panel is inscribed in a substantially horizontal plane.
Préférentiellement, la butée est agencée sur le panneau de structure de l'ouvrant.  Preferably, the stop is arranged on the structural panel of the opening.
Dans des modes de réalisation de l'invention, la bielle présente la forme d'une pièce mince. On rappel ici qu'une « pièce mince » désigne, en génie mécanique, une pièce qui présente une épaisseur dont la dimension est plusieurs fois inférieure à la dimension de la largeur de la pièce. A titre d'exemple, l'épaisseur de la bielle est de quelques millimètres et la largeur de la bielle est de plusieurs centimètres ou dizaines de centimètres. La bielle présente donc une section transversale de dorme rectangulaire.  In embodiments of the invention, the rod has the shape of a thin piece. It is recalled here that a "thin part" designates, in mechanical engineering, a part which has a thickness whose size is several times smaller than the dimension of the width of the part. For example, the thickness of the connecting rod is a few millimeters and the width of the connecting rod is several centimeters or tens of centimeters. The rod thus has a rectangular cross section.
Ainsi, on ménage davantage d'espace dans le volume intérieur du véhicule.  Thus, more space is provided in the interior volume of the vehicle.
Dans des modes de réalisation de l'invention, la bielle s'étend en largeur entre deux flancs latéraux, et le mécanisme comprend deux vérins. Chaque vérin est préférentiellement articulé par sa tige sur un flanc de ladite bielle.  In embodiments of the invention, the connecting rod extends in width between two lateral flanks, and the mechanism comprises two jacks. Each cylinder is preferably articulated by its rod on a side of said rod.
Cette caractéristique permet de répartir les contraintes mécaniques et ainsi de réduire les dimensions des vérins, tout en évitant d'éventuels phénomènes de torsion de la bielle.  This characteristic makes it possible to distribute the mechanical stresses and thus to reduce the dimensions of the jacks, while avoiding possible torsion phenomena of the connecting rod.
Selon un autre aspect, l'invention concerne un ouvrant de véhicule comprenant un panneau de structure auquel est solidaire un mécanisme d'entraînement tel que décrit précédemment.  According to another aspect, the invention relates to a vehicle opening comprising a structural panel which is secured to a drive mechanism as described above.
L'ouvrant est adapté à décrire un mouvement pendulaire lorsque le mécanisme d'entraînement le porte entre une position d'ouverture et une position de fermeture d'une baie du véhicule et inversement. Plus particulièrement, sous l'effet de son propre poids, l'ouvrant est amené à conserver une orientation fixe par rapport à un plan vertical lors d'au moins une partie de son déplacement. The opening is adapted to describe a pendulum movement when the drive mechanism carries it between an open position and a closed position of a vehicle bay and vice versa. More particularly, under the effect of its own weight, the opening is made to maintain a fixed orientation relative to a vertical plane during at least part of its displacement.
Dans des modes particuliers de réalisation de l'invention, l'ouvrant forme un unique ensemble mobile entre la position de fermeture et la position d'ouverture permettant l'accès simultanément à des places avant et arrière du véhicule.  In particular embodiments of the invention, the opening forms a single movable assembly between the closed position and the open position allowing access simultaneously to the front and rear seats of the vehicle.
La fabrication et l'intégration d'un tel ouvrant sur un véhicule, par exemple lors d'une étape de fabrication d'une automobile sur une ligne de production, présente l'avantage d'être rapide et ainsi peu onéreux au regard de la fabrication et l'intégration d'ouvrants individuellement destinés à permettre l'accès de chaque place avant et arrière du véhicule.  The manufacture and integration of such an opening on a vehicle, for example during a step of manufacturing a car on a production line, has the advantage of being fast and thus inexpensive with regard to the manufacture and integration of opening individually designed to allow access to each front and rear position of the vehicle.
Dans des modes de réalisation de l'invention, la bielle est configurée de sorte à former un élément du panneau de structure de l'ouvrant contribuant à l'obturation hermétique de la baie du véhicule lorsque l'ouvrant est en position de fermeture.  In embodiments of the invention, the rod is configured to form an element of the structural panel of the opening contributing to the hermetic closing of the vehicle bay when the door is in the closed position.
La bielle est ainsi destinée à être agencé à la fois au regard de l'environnement extérieur et de l'environnement intérieur du véhicule.  The rod is thus intended to be arranged both in terms of the external environment and the interior environment of the vehicle.
Dans des modes de réalisation de l'invention, l'ouvrant comprend deux vitrages entre lesquels la bielle est interposée de sorte à coopérer hermétiquement lorsque l'ouvrant est en position de fermeture.  In embodiments of the invention, the opening comprises two windows between which the connecting rod is interposed so as to cooperate tightly when the door is in the closed position.
L'invention concerne, selon un autre aspect, un véhicule comprenant un ouvrant de véhicule tel que précédemment décrit. Présentation des figures  According to another aspect, the invention relates to a vehicle comprising a vehicle opening as previously described. Presentation of figures
L'invention sera mieux comprise à la lecture de la description suivante, donnée à titre d'exemple nullement limitatif, et faite en se référant aux figures qui représentent schématiquement:  The invention will be better understood on reading the following description, given by way of non-limiting example, and with reference to the figures which show schematically:

Description détaillée de l'invention Detailed description of the invention
Dans le présent mode de mise en œuvre, donné ici à titre illustratif et non limitatif, un mécanisme 10 d'entraînement d'un ouvrant 20 de véhicule 30 selon l'invention est utilisé dans le cadre de l'entraînement de portes latérales d'un véhicule automobile, permettant l'accès à l'habitacle du véhicule 30. Le terme « ouvrant » désigne donc dans la suite du texte une porte de véhicule automobile.  In the present embodiment, given here by way of nonlimiting illustration, a mechanism 10 for driving a door 20 of the vehicle 30 according to the invention is used in the context of the drive of lateral doors of a motor vehicle, allowing access to the passenger compartment of the vehicle 30. The term "opening" means in the following text a motor vehicle door.
On désigne par « flanc » d'un véhicule 30, dans le présent texte, chacune des deux parties latérales symétriques du véhicule 30 comprenant au moins une baie destinée à être obturée ou ouverte par un ouvrant.  The term "sidewall" of a vehicle 30, in the present text, each of the two symmetrical side portions of the vehicle 30 comprising at least one bay to be closed or opened by an opening.
On considère, dans le présent texte, un repère cartésien lié au véhicule 30 sur lequel est installé le mécanisme 10 d'entraînement selon l'invention, comprenant un axe X parallèle à un axe longitudinal du véhicule 30, c'est-à-dire parallèle au sens d'avance du véhicule 30, un axe Y parallèle à un axe transversal du véhicule 30, orthogonal à l'axe X et s'étendant d'un flanc du véhicule 30 à l'autre, et un axe Z vertical. Les axes X et Y sont sensiblement horizontaux. In the present text, we consider a Cartesian reference linked to the vehicle 30 on which the drive mechanism 10 is installed. the invention, comprising an axis X parallel to a longitudinal axis of the vehicle 30, that is to say parallel to the direction of advance of the vehicle 30, a Y axis parallel to a transverse axis of the vehicle 30, orthogonal to the X axis and extending from one side of the vehicle 30 to the other, and a vertical axis Z. The X and Y axes are substantially horizontal.
Les termes « horizontal » et « vertical », sont désignés par rapport à un plan Χ0Υ défini par plusieurs points matérialisant respectivement le contact entre un pneu du véhicule 30 avec le sol. Plus précisément, un axe dit « horizontal » dans la présente demande est un axe parallèle au plan Χ0Υ et un axe dit « vertical » est un axe orthogonal au plan Χ0Υ.  The terms "horizontal" and "vertical" are designated with respect to a plane Χ0Υ defined by several points respectively materializing the contact between a tire of the vehicle 30 with the ground. More specifically, a so-called "horizontal" axis in the present application is an axis parallel to the plane Χ0Υ and a so-called "vertical" axis is an axis orthogonal to the plane Χ0Υ.
En outre, les termes « haut » et « bas » sont définis le long de l'axe Z, un premier élément agencé plus haut qu'un second élément étant plus éloigné du plan Χ0Υ que ledit second élément.  In addition, the terms "high" and "low" are defined along the Z axis, a first element arranged higher than a second element being further from the plane Χ0Υ than said second element.
Les figures 1 à 4 représentent un véhicule 30 comprenant un ouvrant 20 apte à occuper une position de fermeture du véhicule 30 (figures 1 ), une position intermédiaire (figures 2 et 3) et une position d'ouverture d'une baie du véhicule 30 (figure 4).  Figures 1 to 4 show a vehicle 30 comprising an opening 20 adapted to occupy a closed position of the vehicle 30 (Figures 1), an intermediate position (Figures 2 and 3) and an open position of a vehicle bay 30 (Figure 4).
De manière connue en soi, l'ouvrant 20 comprend un panneau de structure 21 , rigide, sur lequel sont assemblés des éléments de carrosserie et des éléments d'habitacle du véhicule 30, et dans lequel est enserré au moins un vitrage 22, par exemple mobile de façon connu de l'homme du métier.  In a manner known per se, the opening 20 comprises a structural panel 21, rigid, on which are assembled body elements and cabin elements 30 of the vehicle, and wherein is enclosed at least one glazing 22, for example mobile in a manner known to those skilled in the art.
Tel que représenté par les figures 1 à 4, le mécanisme 10 d'entraînement comprend au moins un vérin 1 1 agencé de sorte à pouvoir déplacer une bielle 12 afin d'entraîner l'ouvrant 20 vers la position d'ouverture ou vers la position de fermeture d'une baie du véhicule 30.  As represented by FIGS. 1 to 4, the driving mechanism 10 comprises at least one jack 11 arranged so as to be able to move a connecting rod 12 in order to drive the opening 20 towards the open position or towards the position closing a vehicle bay 30.
Plus précisément, la bielle 12 s'étend en longueur entre deux extrémités dont une première extrémité 121 est configurée pour être solidaire du châssis du véhicule 30, préférentiellement du pied milieu du châssis, et dont une seconde extrémité 122 est configurée pour être solidaire du panneau de structure 21 de l'ouvrant 20. La bielle 12 s'étend également en largeur entre deux flancs latéraux.  More specifically, the connecting rod 12 extends in length between two ends, a first end 121 is configured to be integral with the chassis of the vehicle 30, preferably the middle foot of the frame, and a second end 122 is configured to be secured to the panel 21 of the opening 20. The rod 12 also extends in width between two lateral flanks.
Chacune des extrémités 121 et 122 de la bielle 12 est, dans le mode de réalisation de l'invention représenté par les figures, monté mobile en rotation autour d'un axe de rotation sensiblement parallèle à l'axe X, par des moyens connus de l'homme du métier. L'axe de rotation des extrémités 121 et 122 de la bielle sont donc parallèles l'un par rapport à l'autre. Each of the ends 121 and 122 of the connecting rod 12 is, in the embodiment of the invention represented by the figures, mounted movably in rotation about an axis of rotation substantially parallel to the axis X, by means known to those skilled in the art. The axis of rotation of the ends 121 and 122 of the connecting rod are therefore parallel to one another.
Plus particulièrement, tel que représenté par les figures 1 à 5, la première extrémité 121 de la bielle 12 est montée mobile en rotation sur le pied milieu par le biais d'une articulation, dite première articulation, par exemple formée par un pivot agencé de manière adjacente au toit du châssis. Ainsi, l'ouvrant 20 peut être porté par la bielle 12 de telle sorte que le panneau de structure 21 puisse être entièrement refoulée au-dessus du véhicule 30, la hauteur de refoulement, définie selon l'axe Z, dudit panneau de structure 21 dépendant de la longueur de la bielle 12. Ainsi, la longueur de la bielle 12 est choisie notamment selon la hauteur de refoulement du panneau de structure 21 désirée, et plus particulièrement selon le type de véhicule auquel appartient l'ouvrant 20.  More particularly, as represented by FIGS. 1 to 5, the first end 121 of the connecting rod 12 is rotatably mounted on the center pillar by means of a hinge, called a first hinge, for example formed by a pivot arranged in adjacent to the chassis roof. Thus, the opening 20 can be carried by the connecting rod 12 so that the structure panel 21 can be completely pushed over the vehicle 30, the discharge height, defined along the Z axis of said structure panel 21 depending on the length of the connecting rod 12. Thus, the length of the connecting rod 12 is chosen in particular according to the discharge height of the desired structural panel 21, and more particularly according to the type of vehicle to which the opening part 20 belongs.
En outre, grâce à cette caractéristique le pivot peut présenter une longueur plus important que la largeur de la bielle 12, , comme le représente la figure 8, par exemple en vu de présenter une résistance mécanique élevé aux efforts mis en jeu lors de l'entraînement de l'ouvrant 20 entre ses deux positions extrêmes.  In addition, thanks to this feature, the pivot may have a longer length than the width of the connecting rod 12, as shown in FIG. 8, for example in view of having a high mechanical resistance to the forces involved during the driving the opening 20 between its two extreme positions.
Par ailleurs, la seconde extrémité 122 de la bielle 12 est préférentiellement configurée pour être solidaire du panneau de structure 21 de l'ouvrant 20 en un point plus haut que le centre de gravité dudit panneau 21 lorsqu'elle est en position de fermeture du véhicule 30, tel l'illustre la figure 1 .  Furthermore, the second end 122 of the rod 12 is preferably configured to be secured to the structural panel 21 of the opening 20 at a point higher than the center of gravity of said panel 21 when in the closed position of the vehicle 30, as shown in FIG.
La bielle 12 peut avantageusement être de forme courbe, telle que représentée sur les figures 1 à 4. Avantageusement, la bielle 12 est agencée de sorte que sa courbure soit disposée en regard de l'extérieur du véhicule 30, de façon à ménager davantage d'espace dans l'habitacle du véhicule 30 lorsque l'ouvrant 20 est en position de fermeture du véhicule 30. A cet effet, la bielle peut également avantageusement présenter la forme d'une pièce mince comprenant une faible épaisseur par rapport à sa longueur et à sa largeur. La bielle 12 présente donc alors une section droite transversale sensiblement rectangulaire. Dans un exemple de réalisation, la bielle 12 est réalisée en matériaux composites, tel qu'en fibres de carbone, ou en matériau métallique, tel qu'en aluminium. The connecting rod 12 may advantageously be of curved shape, as shown in FIGS. 1 to 4. Advantageously, the connecting rod 12 is arranged so that its curvature is arranged facing the outside of the vehicle 30, so as to provide more space in the cabin of the vehicle 30 when the opening 20 is in the closed position of the vehicle 30. For this purpose, the connecting rod may also advantageously have the shape of a thin piece having a small thickness relative to its length and at its width. The rod 12 therefore has a substantially rectangular cross section. In an exemplary embodiment, the connecting rod 12 is made of composite materials, such as carbon fibers, or metal material, such as aluminum.
Dans le mode de réalisation décrit dans le présent texte, le vérin 1 1 est d'une part, solidaire de la bielle 12, entre ses deux extrémités, et est, d'autre part, solidaire du châssis du véhicule 30, préférentiellement du pied milieu du châssis.  In the embodiment described in the present text, the cylinder 1 1 is on the one hand, integral with the connecting rod 12, between its two ends, and is, on the other hand, integral with the chassis of the vehicle 30, preferably foot middle of the chassis.
Le vérin 1 1 est adapté à réaliser un mouvement de translation. Dans le mode de réalisation représenté par les figures, le vérin 1 1 comprend un corps de vérin dans lequel une tige de vérin est adaptée à coulisser entre une position initiale, dans laquelle le vérin présente une longueur minimale, l'ouvrant 20 étant en position de fermeture, et une position finale, dans laquelle il présente une longueur maximale, l'ouvrant 20 étant en position d'ouverture.  The cylinder 1 1 is adapted to perform a translational movement. In the embodiment represented by the figures, the cylinder 1 1 comprises a cylinder body in which a cylinder rod is adapted to slide between an initial position, in which the cylinder has a minimum length, the opening 20 being in position. closing, and a final position, in which it has a maximum length, the opening 20 being in the open position.
Le nombre de vérin formant le vérin est notamment déterminé en fonction du poids de l'ouvrant à déplacer.  The number of cylinder forming the cylinder is determined in particular according to the weight of the opening to move.
Tel que représenté de façon chronologique par les figures 1 à 4, le déploiement de le vérin 1 1 de sa position initiale vers sa position finale provoque le déplacement de l'ouvrant 20 d'une position de fermeture à une position d'ouverture du véhicule 30.  As shown chronologically in Figures 1 to 4, the deployment of the cylinder 1 1 from its initial position to its final position causes the movement of the opening 20 from a closed position to an open position of the vehicle 30.
Dans le mode de réalisation représenté par les figures, le vérin 1 1 est solidaire du pied milieu du véhicule 30 par l'extrémité libre du corps du vérin et est solidaire de la bielle 12 par l'extrémité libre de la tige de vérin.  In the embodiment shown in the figures, the cylinder 1 1 is secured to the middle foot of the vehicle 30 by the free end of the cylinder body and is secured to the connecting rod 12 by the free end of the cylinder rod.
Plus précisément, le vérin 1 1 est monté en rotation autour d'un axe parallèle à l'axe X grâce à des rotules implantées sur chacun des flans de la bielle.  More specifically, the cylinder 1 1 is rotatably mounted about an axis parallel to the X axis by means of ball joints implanted on each of the blanks of the rod.
Dans des exemples de réalisation, le mécanisme 10 d'entraînement est dimensionné de sorte que le ou les vérins soient fixés mobiles en rotation sur la bielle 12 dans un segment défini entre un point médian de la bielle 12, situé à égale distance de ses deux extrémités 121 et 122, et la première extrémité 121 de celle-ci. Préférentiellement, le ou les vérins sont montés en rotation sur le pied milieu du châssis par l'intermédiaire d'une articulation de type rotule. Le vérin 1 1 peut avantageusement permettre de compenser le poids de l'ouvrant 20 lors de l'ouverture ou de la fermeture de la baie par un utilisateur, de sorte que l'utilisateur ne fournisse qu'un effort de faible intensité pour le déplacer. In exemplary embodiments, the drive mechanism 10 is dimensioned so that the jack or cylinders are rotatably fixed to the connecting rod 12 in a segment defined between a midpoint of the connecting rod 12, equidistant from its two ends. ends 121 and 122, and the first end 121 thereof. Preferably, the jack or cylinders are rotatably mounted on the middle foot of the frame by means of a hinge-type ball joint. The jack 1 1 can advantageously make it possible to compensate the weight of the opening 20 when opening or closing the bay by a user, so that the user provides a low intensity effort to move it .
Avantageusement, dans d'autres exemples de réalisation de l'invention, le vérin 1 1 peut être moteur de sorte à pouvoir provoquer le déplacement de l'ouvrant 20 en réponse à une consigne d'un utilisateur. En d'autres termes, l'ouverture et la fermeture d'une baie du véhicule 30 peuvent être réalisées de manière automatique, c'est-à-dire, sans manipulation de l'ouvrant 20 par utilisateur. Dans ce cas le vérin 1 1 peut être actionné électriquement ou par d'autres types énergie et connecté à un organe de contrôle et de commande. Dans ce cas, l'organe de contrôle et de commande est adapté à recevoir la consigne d'un utilisateur, par exemple par le biais de moyens de communication sans fil, et à asservir le vérin 1 1 en fonction de ces consignes.  Advantageously, in other embodiments of the invention, the cylinder 1 1 may be motor so as to cause the displacement of the opening 20 in response to a set of a user. In other words, the opening and closing of a vehicle bay 30 can be performed automatically, that is to say, without manipulation of the opening 20 per user. In this case the cylinder 1 1 can be actuated electrically or by other types of energy and connected to a control and control member. In this case, the control and control member is adapted to receive the instruction of a user, for example by means of wireless communication means, and to slave the cylinder 1 1 according to these instructions.
Préférentiellement, le vérin 1 1 comprend un vérin configuré pour compenser le poids de l'ouvrant 20 et un vérin moteur configuré pour déplacer l'ouvrant en réponse à une consigne d'un utilisateur, tels que représentés par la figure 6. On peut voir sur cette figure que les deux vérins peuvent être agencés de manière parallèle l'un par rapport à l'autre, de part et d'autre de la bielle, chaque vérin étant fixé à un flanc de la bielle.  Preferably, the jack 1 1 comprises a jack configured to compensate for the weight of the opening 20 and a motor cylinder configured to move the sash in response to a set point of a user, as shown in Figure 6. It can be seen in this figure that the two cylinders can be arranged parallel to one another, on either side of the connecting rod, each cylinder being attached to a side of the rod.
En outre, le vérin 1 1 peut être monté en rotation sur le pied milieu du châssis par l'intermédiaire d'une articulation de type rotule ou par un pivot agencé au-dessous de la première articulation de la première extrémité 121 de la bielle 12, c'est-à-dire plus proche du plan Χ0Υ et préférentiellement, de manière adjacente au plancher du châssis du véhicule, c'est-à-dire à la jonction entre le plancher et le pied milieu, comme le représente la figure 6. Ainsi, la course de la ou des tiges du ou des vérins est maximisée.  In addition, the cylinder 1 1 can be rotatably mounted on the middle foot of the frame by means of a hinge-type ball joint or a pivot arranged below the first hinge of the first end 121 of the connecting rod 12 , that is to say, closer to the plane Χ0Υ and preferentially, adjacent to the floor of the vehicle frame, that is to say at the junction between the floor and the center pillar, as shown in FIG. 6 Thus, the stroke of the rod or rods or cylinders is maximized.
Une butée est adaptée à limiter le débattement angulaire de l'ouvrant 20 par rapport à la bielle lors de son déplacement vers la position d'ouverture d'une baie du véhicule 30, de sorte que l'ouvrant 20 soit inscrit dans un plan sensiblement horizontal, c'est-à-dire parallèle au plan Χ0Υ, lorsqu'il est en position d'ouverture. Plus précisément, le débattement de l'ouvrant est du type pendulaire, c'est-à-dire que ledit ouvrant est entraîné en rotation par son propre poids, lors de son déplacement entre la position d'ouverture et la position de fermeture et inversement. Ainsi, l'ouvrant conserve une orientation fixe par rapport à un plan vertical, sensiblement parallèle à un plan XOZ, lors d'au moins une portion de son déplacement dans laquelle le débattement angulaire dudit ouvrant n'est pas limité par la butée, comme le montrent les figures successives 1 à 4. A stop is adapted to limit the angular displacement of the opening 20 relative to the connecting rod during its movement towards the open position of a vehicle bay 30, so that the opening 20 is inscribed in a plane substantially horizontal, that is to say parallel to the plane Χ0Υ, when it is in the open position. More specifically, the clearance of the opening is of the type pendulum, that is to say that said opening is rotated by its own weight, during its movement between the open position and the closed position and vice versa. Thus, the opening maintains a fixed orientation relative to a vertical plane, substantially parallel to a plane XOZ, during at least a portion of its displacement in which the angular displacement of said leaf is not limited by the stop, as show the successive figures 1 to 4.
Avantageusement, si l'ouvrant est inscrit dans un plan P sensiblement vertical, c'est-à-dire sensiblement parallèle à un plan XOZ, lorsque ledit ouvrant est en position de fermeture et sensiblement horizontal, c'est-à-dire sensiblement parallèle au plan XOY, lorsqu'il est en position d'ouverture, et si la bielle est inscrite dans un plan P' passant par ses extrémités 121 et 122, tels que représentés sur les figures 3 et 4, le débattement angulaire maximal de l'ouvrant 20 par rapport à la bielle peut être tel qu'un angle a définit entre les plans P et P' est égale à environ soixante-quinze degrés.  Advantageously, if the leaf is inscribed in a substantially vertical plane P, that is to say substantially parallel to a plane XOZ, when said leaf is in the closed position and substantially horizontal, that is to say substantially parallel XOY plane, when in the open position, and if the connecting rod is inscribed in a plane P 'passing through its ends 121 and 122, as shown in Figures 3 and 4, the maximum angular deflection of the opening 20 relative to the connecting rod may be such that an angle α defines between the planes P and P 'is equal to about seventy-five degrees.
Lors de son évolution de la position de fermeture à la position d'ouverture, l'ouvrant 20 est donc entraîné par son propre poids à pivoter de façon à passer d'une position dans laquelle le plan P est sensiblement vertical à une position dans laquelle le plan P est sensiblement horizontal. Il y a lieu de noter que, de manière analogue, lors de son évolution de la position d'ouverture à la position de fermeture, l'ouvrant 20 est entraîné par son propre poids à pivoter de façon à passer d'une position dans laquelle le plan P est sensiblement horizontal à une position dans laquelle le plan P est sensiblement vertical.  During its evolution from the closed position to the open position, the opening 20 is thus driven by its own weight to pivot so as to pass from a position in which the plane P is substantially vertical to a position in which the plane P is substantially horizontal. It should be noted that, similarly, during its evolution from the open position to the closed position, the opening 20 is driven by its own weight to pivot so as to move from a position in which the plane P is substantially horizontal at a position in which the plane P is substantially vertical.
Alternativement, l'ouvrant 20 peut être incliné de quelques degrés, par exemple de un à dix degrés, selon un axe parallèle à l'axe X, vers le véhicule 30. Cette caractéristique permet à l'ouvrant 20, lorsqu'il est en position d'ouverture, de former une paroi de protection de l'utilisateur, notamment contre les intempéries.  Alternatively, the opening 20 can be inclined by a few degrees, for example from one to ten degrees, along an axis parallel to the axis X, towards the vehicle 30. This characteristic allows the opening 20, when it is in opening position, to form a protective wall of the user, especially against the weather.
Avantageusement, pour des raisons de compacité, la butée est disposée de sorte à définir le moment auquel le pivotement de l'ouvrant 20 par rapport à un plan vertical, sensiblement parallèle à un plan XOZ, est effectué, lors de sa course entre la position de fermeture et la position d'ouverture et inversement. Plus particulièrement, le pivotement de l'ouvrant 20, d'une position dans laquelle le plan P est sensiblement vertical à une position dans laquelle le plan P est sensiblement horizontal est préférentiellement réalisé vers les deux tiers de la course de l'ouvrant. Advantageously, for reasons of compactness, the stop is arranged so as to define the moment at which the pivoting of the opening 20 with respect to a vertical plane, substantially parallel to a plane XOZ, is effected, during its course between the position closing and the open position and Conversely. More particularly, the pivoting of the opening 20, a position in which the plane P is substantially vertical at a position in which the plane P is substantially horizontal is preferably made to two thirds of the stroke of the opening.
En outre, comme illustré par la figure 4, le mécanisme 10 d'entraînement est préférentiellement dimensionné de sorte que lorsqu'il est en position d'ouverture, l'ouvrant 20 est entièrement étendu au-dessus du véhicule 30.  In addition, as illustrated in FIG. 4, the drive mechanism 10 is preferably dimensioned so that when it is in the open position, the opening 20 is entirely extended above the vehicle 30.
Ces dispositions permettent avantageusement à un utilisateur de pouvoir stationner son véhicule 30 à des places de stationnement dans lesquelles l'espace latéral entre le flanc du véhicule 30 et un obstacle, c'est-à- dire l'espace d'accès à l'habitacle du véhicule 30 est relativement faible, tel qu'illustré schématiquement par les figures 1 à 4.  These arrangements advantageously allow a user to park his vehicle 30 in parking spaces in which the lateral space between the sidewall of the vehicle 30 and an obstacle, that is to say the access space to the vehicle interior 30 is relatively small, as schematically illustrated in Figures 1 to 4.
Les figures 5 et 6 représentent un véhicule 30 dont un ouvrant 20 est entraîné par le mécanisme 10 d'entraînement selon l'invention. L'ouvrant 20 forme un unique ensemble mobile entre la position de fermeture et la position d'ouverture d'une baie permettant l'accès simultanément aux places avant et arrière du véhicule 30, c'est-à-dire aux places avant et arrière du véhicule 30. Autrement dit, l'ouvrant 20 forme une porte latérale unique avant et arrière du véhicule. La bielle 12 est alors dimensionnée de sorte à être interposée hermétiquement entre deux vitrages 22 lorsque l'ouvrant est en position de fermeture. La bielle est donc configurée de sorte à former un élément de panneau de structure de l'ouvrant, c'est-à-dire qu'elle contribue à l'obturation hermétique de la baie du véhicule lorsque l'ouvrant occupe la position de fermeture. Autrement dit, la bielle est configurée de sorte à former un élément de carrosserie du véhicule lorsque le véhicule est fermé, agencé à la fois au regard de l'environnement extérieur et de l'environnement intérieur du véhicule 30, comme le montre la figure 7. Cette caractéristique est rendu possible grâce à la fixation de la bielle sur le pied milieu. Des joints d'étanchéité à l'eau et à l'air sont agencés sur les flancs de la bielle 12, de sorte que lors de la fermeture de l'ouvrant les vitrages 22 viennent comprimer lesdits joints et ainsi créer l'étanchéité.  Figures 5 and 6 show a vehicle 30 of which an opening 20 is driven by the drive mechanism 10 according to the invention. The opening 20 forms a single movable assembly between the closed position and the open position of a bay allowing simultaneous access to the front and rear seats of the vehicle 30, that is to say to the front and rear seats of the vehicle 30. In other words, the opening 20 forms a single side door front and rear of the vehicle. The rod 12 is then dimensioned so as to be interposed hermetically between two panes 22 when the opening is in the closed position. The rod is thus configured to form a structural panel member of the opening, that is to say, it contributes to the sealing of the vehicle bay when the door is in the closed position . In other words, the rod is configured to form a bodywork element of the vehicle when the vehicle is closed, arranged both with respect to the external environment and the interior environment of the vehicle 30, as shown in Figure 7 This feature is made possible by attaching the connecting rod to the center stand. Water and air seals are arranged on the sidewalls of the rod 12, so that when closing the opening glazing 22 come to compress said joints and thus create the seal.
L'ouvrant 20 formant un unique ensemble mobile permettant l'accès simultanément aux places avant et arrière du véhicule 30, il comprend avantageusement un unique joint d'étanchéité sur au moins une portion de sa périphérie. Plus précisément, ce joint, formé d'un seul tenant, est prévu pour être comprimé par des éléments de carrosserie ou des éléments de châssis du véhicule lors de la fermeture de l'ouvrant. The opening 20 forming a single mobile assembly allowing access simultaneously to the front and rear seats of the vehicle 30, it advantageously comprises a single seal on at least a portion of its periphery. More specifically, this seal, formed in one piece, is intended to be compressed by body members or vehicle frame members when closing the door.
Avantageusement, l'ouvrant 20 peut comprendre un unique organe de verrouillage, par exemple fixé au pied milieu. Cet unique organe de verrouillage peut être connu en soi de l'homme du métier et assurer un verrouillage progressif de l'ouvrant 20 lorsqu'il est en position de fermeture.  Advantageously, the opening 20 may comprise a single locking member, for example fixed to the central pillar. This single locking member may be known per se to those skilled in the art and ensure a progressive locking of the opening 20 when in the closed position.
Le véhicule 30 peut alors ne comporter que deux organes de verrouillage, un par ouvrant 20. Cette disposition permet une économie évidente de temps de montage du véhicule, participant ainsi à la réduction du coût final du véhicule 30.  The vehicle 30 may then have only two locking members, one per opening 20. This arrangement allows an obvious saving of vehicle assembly time, thus contributing to the reduction of the final cost of the vehicle 30.
De manière plus générale, il est à noter que les modes de mise en œuvre et de réalisation considérés ci-dessus ont été décrits à titre d'exemples non limitatifs, et que d'autres variantes sont par conséquent envisageables.  More generally, it should be noted that the modes of implementation and realization considered above have been described by way of non-limiting examples, and that other variants are therefore possible.
Notamment, l'invention a été décrite en considérant principalement un mécanisme 10 d'entraînement d'un ouvrant 20 de véhicule 30 automobile. Rien n'exclut cependant, suivant d'autres exemples, de considérer d'autres types d'ouvrants et/ou de véhicule.  In particular, the invention has been described considering mainly a mechanism 10 for driving an opening 20 of a motor vehicle. Nothing, however, excludes, according to other examples, to consider other types of opening and / or vehicle.
