Description

DISPOSITIF D'OBTURATION D'ENTREE D'AIR DE FACE AVANT DE VEHICULE AUTOMOBILE ET PROCEDE DE FABRICATION  FRONT FACE AIR INTAKE DEVICE FOR MOTOR VEHICLE AND METHOD OF MANUFACTURE
La présente invention concerne les dispositifs d'obturation et plus précisément un dispositif d'obturation d'entrée d'air de face avant de véhicule automobile ainsi que son procédé de fabrication. La présente invention concerne également un véhicule comprenant un tel dispositif d'obturation. The present invention relates to shutter devices and more specifically to a device for closing the air inlet of the front face of a motor vehicle as well as to its method of manufacture. The present invention also relates to a vehicle comprising such a closure device.
Les faces avant de véhicules automobiles sont généralement composées de deux entrées d'air principales dites voie haute et voie basse. Ces entrées d'air sont généralement séparées par une poutre pare-choc. Derrière cette poutre pare-choc sont placés les échangeurs de chaleur du véhicule automobile, comme par exemple celui utilisé pour la climatisation de l'habitacle et/ou encore celui utilisé pour le refroidissement du moteur. The front faces of motor vehicles are generally composed of two main air inlets called high and low lane. These air intakes are usually separated by a bumper beam. Behind this bumper beam are placed the heat exchangers of the motor vehicle, such as that used for the air conditioning of the passenger compartment and / or that used for cooling the engine.
Il est également connu de disposer, dans le trajet d'air passant par les entrées d'air principales, plus généralement la voie basse, un cadre support comportant une multitude de volets montés pivotant autour d'axes parallèles et propres à prendre une multitude de positions angulaires différentes, comprises entre une position d'ouverture et une position d'obturation, sous l'action de moyens de commande appropriés. It is also known to have, in the air path passing through the main air intakes, more generally the lower channel, a support frame comprising a multitude of flaps mounted pivoting about parallel axes and adapted to take a multitude of different angular positions, between an open position and a closed position, under the action of appropriate control means.
On obtient ainsi un dispositif d'obturation s'apparentant à une jalousie qui permet d'ajuster le débit d'air traversant les entrées d'air et arrivant aux échangeurs de chaleur. Il est ainsi possible d'optimiser l'efficacité de ces échangeurs de chaleur en fonction des besoins et en faisant varier la quantité d'air qu'ils reçoivent. De plus, à grande vitesse, les volets en position d'obturation permettent de diminuer le coefficient de traînée du véhicule et ainsi améliorent l'aérodynamisme dudit véhicule. Les dispositifs d'obturation sont fixés à l'avant du véhicule automobile et notamment les volets subissent la pression de l'air lorsque le véhicule automobile est en mouvement ce qui oblige à avoir des fixations de ces volets suffisamment fortes et donc élaborées et coûteuses. De plus, si une intervention d'entretien ou de réparation est nécessaire, il est généralement nécessaire de retirer le dispositif d'obturation du véhicule. This provides a shutter device similar to a jalousie that adjusts the air flow through the air inlets and arriving at the heat exchangers. It is thus possible to optimize the efficiency of these heat exchangers as needed and by varying the amount of air they receive. In addition, at high speed, shutters in the closed position reduce the drag coefficient of the vehicle and thus improve the aerodynamics of said vehicle. The shutter devices are attached to the front of the motor vehicle and in particular the shutters are subjected to air pressure when the motor vehicle is moving which requires to have fasteners of these shutters sufficiently strong and therefore elaborate and expensive. In addition, if a maintenance or repair intervention is necessary, it is generally necessary to remove the shutter device from the vehicle.
Un des buts de la présente invention est donc de remédier au moins partiellement aux inconvénients de l'art antérieur et de proposer un dispositif d'obturation amélioré ainsi que son procédé de fabrication. An object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved closure device and its manufacturing process.
La présente invention concerne donc un dispositif d'obturation pour entrée d'air de face avant de véhicule automobile, comprenant : The present invention thus relates to a shutter device for front air intake of a motor vehicle, comprising:
0 un cadre support dans lequel est installé au moins un ensemble de volets pivotants autour d'axes de pivotement entre une position d'obturation et une position d'ouverture, ledit cadre support comportant une face avant orientée vers l'avant du véhicule automobile et une face arrière orientée vers l'arrière du véhicule, 0 wherein a support frame is installed at least one set of pivoting flaps around pivot axes between a closed position and an open position, said support frame comprising a pre-oriented front face of the motor vehicle and a rear face facing the rear of the vehicle,
0 au moins un élément de commande configuré pour piloter le positionnement des volets, ledit élément de commande comportant : 0 at least one control member configured to control the positioning of the flaps, said control element comprising:
■ au moins un organe de commande relié aux volets, ■ at least one control member connected to the flaps,
■ un actionneur, et ■ an actuator, and
■ un levier relié d'une part à l'actionneur et d'autre part à l'organe de commande de sorte à pouvoir faire pivoter les volets, ■ a lever connected at one end to the actuator and secondly to the control member so as to rotate the shutters,
le cadre support comportant en outre : 0 un logement comportant une ouverture sur la face avant du cadre support, l'élément de commande étant disposé au sein dudit logement de sorte à être accessible via l'ouverture du logement, the support frame further comprising: 0 a housing having an opening on the front face of the support frame, the control element being disposed within said housing so as to be accessible via the housing opening,

De même que pour les éléments présents dans le logement, les volets sont ainsi directement accessibles par l'avant du véhicule ce qui évite de devoir retirer complètement le dispositif d'obturation du véhicule automobile pour pouvoir y accéder, notamment dans le cas d'une réparation ou d'un entretien. De plus, lorsque le véhicule automobile est en mouvement, les volets sont plaqués contre le cadre support et donc leur fixation à ce dernier a moins besoin d'être suffisamment forte pour résister à la pression exercée par l'air.  The fact that the bearings are arranged on the front face of the support frame and allows to mount the flaps by the front of the support frame. As for the elements present in the housing, the flaps are thus directly accessible from the front of the vehicle which avoids having to completely remove the shutter device of the motor vehicle to be able to access it, especially in the case of a vehicle. repair or maintenance. In addition, when the motor vehicle is moving, the flaps are pressed against the support frame and therefore their attachment to the latter has less need to be strong enough to withstand the pressure exerted by the air.

Sur les figures 1 à 6 et 12 à 15, un trièdre XYZ montre l'orientation des différentes pièces notamment lorsqu'elles sont montées sur un véhicule automobile. Les axes de ce trièdre peuvent ainsi correspondre aux différentes orientations du véhicule automobile. L'axe X peut ainsi correspondre à la longueur du véhicule, le vecteur X indiquant l'avant du véhicule. L'axe Y peut quant à lui correspondre à la largeur du véhicule et l'axe Z à sa hauteur. In Figures 1 to 6 and 12 to 15, an XYZ trihedron shows the orientation of the various parts including when mounted on a motor vehicle. The axes of this trihedron can thus correspond to different orientations of the motor vehicle. The X axis can thus correspond to the length of the vehicle, the X vector indicating the front of the vehicle. The Y axis can correspond to the width of the vehicle and the Z axis to its height.
La figure 1 montre une représentation schématique en perspective d'un dispositif d'obturation 1 en position d'obturation. Cette figure 1 montre plus exactement la face externe du dispositif d'obturation 1, c'est-à-dire la face dirigée vers l'extérieur du véhicule automobile lorsque le dispositif d'obturation 1 est assemblé sur le véhicule. Le dispositif d'obturation 1 est disposé en face avant du véhicule automobile, au devant d'échangeurs de chaleurs tels qu'un radiateur, ou d'autres échangeurs comme par exemple un refroidisseur d'air de suralimentation, un condenseur d'un circuit de climatisation. Le dispositif d'obturation 1 comporte un cadre support 5 comprenant notamment deux traverses longitudinales 5 a, s'étendant parallèlement à l'axe Y du trièdre, et au moins deux montants latéraux 5b, s'étendant parallèlement à l'axe Z du trièdre, et reliant les traverses longitudinales 5 a. Le cadre support 5 est réalisé par exemple en matière plastique. Les deux traverses longitudinales 5a et les au moins deux montants latéraux 5b sont ainsi moulés. Afin d'améliorer la rigidité du cadre support 5, ce dernier peut être moulé en une seule pièce. Le cadre support 5 comporte notamment une face avant, c'est-à-dire qui est orientée vers l'avant du véhicule automobile, selon le vecteur X du trièdre, et une face arrière, c'est-à-dire qui est orientée vers l'arrière du véhicule automobile, à l'inverse du vecteur X du trièdre. Figure 1 shows a schematic perspective view of a shutter device 1 in the closed position. This Figure 1 shows more exactly the outer face of the closure device 1, that is to say the face facing the outside of the motor vehicle when the closure device 1 is assembled on the vehicle. The closure device 1 is disposed on the front face of the motor vehicle, in front of heat exchangers such as a radiator, or other exchangers such as for example a charge air cooler, a condenser of a circuit air conditioning. The closure device 1 comprises a support frame 5 comprising in particular two longitudinal crosspieces 5a, extending parallel to the Y axis of the trihedron, and at least two lateral uprights 5b, extending parallel to the Z axis of the trihedron and connecting the longitudinal struts 5 a. The support frame 5 is made for example of plastic. The two longitudinal crosspieces 5a and the at least two lateral uprights 5b are thus molded. In order to improve the rigidity of the support frame 5, the latter can be molded in one piece. The support frame 5 comprises in particular a front face, that is to say which is oriented towards the front of the motor vehicle, according to the vector X of the trihedron, and a rear face, that is to say which is oriented towards the rear of the motor vehicle, unlike the vector X of the trihedron.
Au sein du cadre support 5 est installés une pluralité de volets 3, ces derniers forment des rangs de volets 3 parallèles entre eux et forment des ensembles 3a, 3b et 3c de volets 3. Le dispositif d'obturation 1 comporte également un élément de commande 13 configuré pour piloter la rotation du ou des volets 3 autour d'un axe de pivotement A, entre une position d'ouverture, où les volets 3 sont positionnés de sorte qu'un flux d'air puisse traverser le dispositif d'obturation 1, notamment à l'intérieur du cadre support 5, et une position d'obturation illustrée à la figure 1 , où les volets 3 sont positionnés de sorte qu'un flux d'air ne puisse pas traverser le dispositif d'obturation 1. L'élément de commande 13 peut être disposé sur un côté du dispositif d'obturation 1 au niveau d'un montant latéral 5b ou encore entre deux ensembles de volets 3 comme illustré sur la figure 1.  Within the support frame 5 are installed a plurality of flaps 3, the latter form rows of shutters 3 parallel to each other and form assemblies 3a, 3b and 3c of flaps 3. The shutter device 1 also comprises a control element 13 configured to control the rotation of the or flaps 3 about a pivot axis A, between an open position, where the flaps 3 are positioned so that a flow of air can pass through the shutter device 1 , especially inside the support frame 5, and a closed position illustrated in Figure 1, wherein the flaps 3 are positioned so that an air flow can not pass through the closure device 1. L the control element 13 may be arranged on one side of the closure device 1 at a lateral upright 5b or between two sets of flaps 3 as illustrated in FIG. 1.
La figure 1 montre plus spécifiquement un dispositif d'obturation 1 comprenant trois ensembles 3a, 3b et 3c de volets 3. Comme le montre la figure 2 qui est une représentation schématique éclatée d'un dispositif d'obturation 1, l'élément de commande 13 comporte notamment au moins un organe de commande 7 relié aux volets 3, un actionneur 9, et un levier 11 relié d'une part à l'actionneur 9 et d'autre part à l'organe de commande 7 de sorte à pouvoir faire pivoter les volets 3. FIG. 1 more specifically shows a shutter device 1 comprising three sets 3a, 3b and 3c of shutters 3. As shown in FIG. 2 which is an exploded schematic representation of a shutter device 1, the control element 13 comprises in particular at least one control member 7 connected to the shutters 3, an actuator 9, and a lever 11 connected with a on the actuator 9 and on the other hand to the control member 7 so as to be able to rotate the flaps 3.
Le cadre support 5 comporte un logement 20 dans lequel est disposé l'élément de commande 13 et tout ses éléments. Le logement 20 comporte une ouverture sur la face avant du cadre support 5. Le logement 20 est borgne, c'est-à-dire qu'il comporte un fond sur la face arrière du cadre support 5. Un capot 30 vient recouvrir l'ouverture du logement 20 en face avant du cadre support 5 afin de protéger l'élément de commande 13.  The support frame 5 comprises a housing 20 in which is disposed the control element 13 and all its elements. The housing 20 has an opening on the front face of the support frame 5. The housing 20 is blind, that is to say it has a bottom on the rear face of the support frame 5. A cover 30 covers the back opening the housing 20 on the front face of the support frame 5 in order to protect the control element 13.
Le fait que le logement 20 comporte une ouverture sur la face avant du cadre support 5 permet tout d'abord un accès plus aisé à l'élément de commande 13, notamment dans le cas d'une réparation ou d'un entretien. L'actionneur 9, le levier 11 et l'organe de commande 7 sont ainsi directement accessibles par l'avant du véhicule ce qui évite de devoir retirer complètement le dispositif d'obturation 1 du véhicule automobile pour pouvoir y accéder.  The fact that the housing 20 has an opening on the front face of the support frame 5 first allows easier access to the control element 13, especially in the case of a repair or maintenance. The actuator 9, the lever 11 and the control member 7 are thus directly accessible from the front of the vehicle which avoids having to completely remove the shutter device 1 of the motor vehicle to access it.
L'ouverture du logement 20 est notamment suffisante afin de pouvoir installer et retirer l'ensemble des éléments de l'élément de commande 13.  The opening of the housing 20 is in particular sufficient to be able to install and remove all the elements of the control element 13.
Le cadre support 5 comporte également au moins deux rangées parallèles de paliers 51 d'engagement des axes de pivotement A des volets 3. Ces rangées de paliers 51 sont disposées sur le cadre support 5 de sorte à recevoir les axes de pivotement A des volets 3. Une rangée de paliers 51 est disposée de part et d'autre de chaque ensemble de volets 3. Plus particulièrement, ces rangées de paliers 51 sont parallèles à l'axe Z du trièdre et disposées sur la face avant du cadre support 5. Le fait que les paliers 51 soient disposés sur la face avant du cadre support 5 permet ainsi de monter les volets 3 par l'avant du cadre support 5. De même que pour les éléments présents dans le logement 20, les volets 3 sont ainsi directement accessibles par l'avant du véhicule ce qui évite de devoir retirer complètement le dispositif d'obturation 1 du véhicule automobile pour pouvoir y accéder, notamment dans le cas d'une réparation ou d'un entretien. De plus, lorsque le véhicule automobile est en mouvement, les volets 3 sont plaqués contre le cadre support 5 et donc leur fixation à ce dernier a moins besoin d'être suffisamment forte pour résister à la pression exercée par l'air. The support frame 5 also comprises at least two parallel rows of bearings 51 for engaging the pivot axes A of the flaps 3. These rows of bearings 51 are arranged on the support frame 5 so as to receive the pivot axes A of the flaps 3 A row of bearings 51 is disposed on either side of each set of flaps 3. More particularly, these rows of bearings 51 are parallel to the Z axis of the trihedron and arranged on the front face of the support frame 5. The fact that the bearings 51 are arranged on the front face of the support frame 5 thus allows the flaps 3 to be mounted by the front of the support frame 5. As for the elements present in the housing 20, the flaps 3 are thus directly accessible from the front of the vehicle which avoids having to completely remove the shutter device 1 of the motor vehicle to access it, especially in the case of repair or maintenance. In addition, when the motor vehicle is in motion, the flaps 3 are pressed against the support frame 5 and therefore their attachment to the latter has less need to be strong enough to withstand the pressure exerted by the air.
La figure 3 montre plus en détail la liaison entre les volets 3 et l'organe de commande 7. Les volets 3 comportent chacun un bras de commande 39, perpendiculaire à leur axe de pivotement A et portant un axe de liaison B permettant la liaison entre ledit bras de commande 39 et l'organe de commande 7. Le bras de commande 39 vient généralement de matière avec les volets 3. FIG. 3 shows in more detail the connection between the flaps 3 and the control member 7. The flaps 3 each comprise a control arm 39, perpendicular to their pivot axis A and carrying a connection axis B allowing the connection between said control arm 39 and the control member 7. The control arm 39 is generally made of material with the flaps 3.
Les volets 3 peuvent pivoter chacun autour de leur axe de pivotement A défini par leur liaison avec le cadre support 5 au niveau des paliers 51. Les axes de liaison B entre les volets 3 et l'organe de commande 7 sont excentrés par rapport aux axes de pivotement A de sorte qu'un mouvement de translation, parallèlement à l'axe Z du trièdre, de l'organe de commande 7, sous l'action de l'actionneur 9, entraîne le pivotement des volets 3 autour de leurs axes de pivotement A respectifs et donc le passage desdits volets 3 d'une position à une autre.  The flaps 3 can pivot each about their pivot axis A defined by their connection with the support frame 5 at the bearings 51. The connecting pins B between the flaps 3 and the control member 7 are eccentric with respect to the axes of pivoting A so that a translation movement, parallel to the Z axis of the trihedron, of the control member 7, under the action of the actuator 9, causes the pivoting of the flaps 3 around their axes of rotation. respective pivoting A and thus the passage of said flaps 3 from one position to another.
Tous les volets 3 étant reliés au même organe de commande 7, le passage d'une position d'ouverture à une position d'obturation est synchrone pour tous les volets 3.  All the shutters 3 being connected to the same control member 7, the passage from an open position to a closed position is synchronous for all the shutters 3.
Comme illustré sur les figures 3 et 4, l'organe de commande 7 comporte sur une première face 7a (visible sur la figure 3), un premier logement oblong 73 dont le grand axe est orienté parallèlement à l'axe X et perpendiculairement au déplacement de l'organe de commande 7. Cette première face 7a est destinée à être orientée vers l'intérieur du logement 20 et ce premier logement oblong 73 est destiné à recevoir un pion l ia du levier 11. Ce premier logement oblong 73 est notamment disposé sur une face de l'organe de commande 7 opposée à sa face en liaison avec les volets 3. Le premier logement oblong 73 peut notamment être ouvert sur un de ses petits côtés afin de faciliter le montage et l'insertion du levier 11 dans le premier logement oblong 73. As illustrated in FIGS. 3 and 4, the control member 7 comprises on a first face 7a (visible in FIG. 3), a first oblong slot 73 whose major axis is oriented parallel to the axis X and perpendicular to the displacement of the control member 7. This first face 7a is intended to be oriented towards the interior of the housing 20 and this first oblong housing 73 is intended to receive a pinion l ia of the lever 11. This first oblong slot 73 is in particular disposed on a face of the control member 7 opposite its face in connection with the flaps 3. The first oblong slot 73 may in particular be open on one of its small sides to facilitate mounting and insertion of the lever 11 into the first slot 73.
Le fait que le premier logement oblong 73 a cette forme oblongue permet une conversion et une transmission du mouvement rotatif du levier 11 en un mouvement de translation rectiligne de l'organe de commande 7 sans qu'il y ait de déplacement en profondeur (selon l'axe X) de l'organe de commande 7. Lors de la translation de l'organe de commande 7, le levier 11 peut ainsi se déplacer dans le premier logement oblong 73 selon son grand axe et faire translater l'organe de commande 7.  The fact that the first oblong slot 73 has this oblong shape allows a conversion and a transmission of the rotary movement of the lever 11 into a rectilinear translational movement of the control member 7 without there being any displacement in depth (according to FIG. X axis) of the control member 7. During the translation of the control member 7, the lever 11 can move in the first slot 73 along its long axis and translate the control member 7 .
L'organe de commande 7 peut comporter également sur une deuxième face 7b (visible sur la figure 4) au moins un deuxième logement oblong 74 dont le grand axe est également orienté perpendiculairement à la première liaison glissière. Cette deuxième face 7b est destinée à être orientée vers l'extérieur du logement 20 en direction des volets 3. Les deuxièmes logements oblong 74 sont quant à eux destinés à être connectés à un volet 3, plus précisément à son axe de liaison B. Ces deuxièmes logements oblongs 74 peuvent notamment être ouverts sur un de leurs petits côtés afin de faciliter le montage et l'insertion des axes de liaison B. Lors de la translation de l'organe de commande 7, les axes de liaison B des volets 3 peuvent ainsi se déplacer dans les deuxièmes logements oblongs 74 selon leur grands axes et transformer le mouvement rectiligne de translation de l'organe de commande 7 en un mouvement rotatif du bras de commande 39 autour de l'axe de rotation A et ainsi faire pivoter les volets 3. The control member 7 may also comprise on a second face 7b (visible in Figure 4) at least a second oblong housing 74 whose major axis is also oriented perpendicular to the first slide connection. This second face 7b is intended to be oriented towards the outside of the housing 20 towards the flaps 3. The second oblong housings 74 are for their part to be connected to a flap 3, more precisely to its connecting axis B. second oblong housings 74 can in particular be opened on one of their short sides to facilitate the assembly and insertion of the connecting pins B. During the translation of the control member 7, the connecting axes B of the flaps 3 can thus move in the second oblong housings 74 along their major axes and transform the rectilinear translation movement of the control member 7 into a rotary movement of the control arm 39 around the axis of rotation A and thus rotate the flaps 3.
Tous les volets 3 sont reliés au même organe de commande 7, le passage d'une position d'ouverture à une position d'obturation est synchrone pour tous les volets 3. Sur les figures 2 à 4, l'exemple d'organe de commande 7 est un organe de commande 7 simple qui ne commande qu'un ensemble de volets 3 disposé sur un seul côté de l'élément de commande 13. Dans le cas où un ensemble de volets 3 serait présent de part et d'autre de l'élément de commande 13 comme sur la figure 1, l'organe de commande 7 peut avoir une section en forme de U (non représentée) avec des deuxièmes logements oblongs 74 disposés sur les deux branches du U afin de commander les deux ensembles de volets 3 simultanément. Une traverse relie les deux branches du U et permet de transmettre un mouvement synchrone aux deux ensembles de volets 3. De plus cette section en forme de U permet de surmonter l'actionneur 9 et le levier 11 qui sont disposés dans le logement 20 entre les branches du U. Comme illustré aux figures 5 et 6, l'organe de commande 7 est monté au sein du logement 20 par une première liaison glissière, réalisée entre une paroi latérale 22 interne dudit logement 20 et ledit organe de commande 7. Par paroi latérale 22 interne, on entend ici que la face de la paroi latérale 22 du logement 20 portant la première liaison glissière est une de ses faces internes située dans le plan formé par les axes X et Z, située à l'intérieur du logement 22. Cette première liaison glissière est configurée pour limiter les mouvements en profondeur (selon l'axe X) et latéraux (selon l'axe Y) de l'organe de commande 7 et pour le guider dans ses mouvements de translation (selon l'axe Z). La première liaison glissière comporte au moins un tenon 71 disposé sur l'organe de commande 7 (visible sur les figures 3 et 4) et venant en prise sur au moins un rail 21 (visible sur la figure 5) disposé sur la paroi latérale 22 du logement 20, de sorte à restreindre les mouvements latéraux (selon l'axe Y) de l'organe de commande 7 et guider sa translation (selon l'axe Z). Il est néanmoins tout à fait possible d'imaginer, sans sortir du cadre de l'invention, une disposition inverse où le rail 21 est disposé sur l'organe de commande 7 et où l'au moins un tenon 71 est disposé sur la paroi latérale 22 interne. Dans l'exemple présenté aux figures 3 à 6, la liaison glissière comporte deux tenon 71, chaque tenon 71 étant en liaison avec un rail 21 dédié. Les rails 21 sont alignés et séparés d'un espacement. Les tenons 71 sont également séparés pour une bonne stabilité et un meilleur guidage de l'organe de commande 7. All the flaps 3 are connected to the same control member 7, the passage from an open position to a closed position is synchronous for all the flaps 3. In FIGS. 2 to 4, the example of control 7 is a simple control member 7 which controls only a set of flaps 3 arranged on one side only of the control element 13. In the case where a set of flaps 3 is present on either side of the control element 13 as in FIG. 1, the control member 7 may have a section in the form of U (not shown) with second oblong housings 74 arranged on the two branches of the U to control the two sets of flaps 3 simultaneously. A cross member connects the two branches of the U and makes it possible to transmit a synchronous movement to the two sets of flaps 3. Moreover, this U-shaped section makes it possible to overcome the actuator 9 and the lever 11 which are arranged in the housing 20 between the branches of the U. As illustrated in Figures 5 and 6, the control member 7 is mounted within the housing 20 by a first slide connection, made between an inner side wall 22 of said housing 20 and said control member 7. By wall internal lateral 22, here means that the side of the side wall 22 of the housing 20 carrying the first slide connection is one of its inner faces located in the plane formed by the X and Z axes, located inside the housing 22. This first slide link is configured to limit the movements in depth (along the X axis) and lateral (along the Y axis) of the control member 7 and to guide it in its translational movements (along the Z axis ). The first slide connection comprises at least one pin 71 disposed on the control member 7 (visible in Figures 3 and 4) and engaging on at least one rail 21 (visible in Figure 5) disposed on the side wall 22 housing 20, so as to restrict the lateral movements (along the Y axis) of the control member 7 and guide its translation (along the Z axis). It is nevertheless quite possible to imagine, without departing from the scope of the invention, an inverse arrangement where the rail 21 is disposed on the control member 7 and where the at least one pin 71 is disposed on the wall lateral 22 internal. In the example shown in Figures 3 to 6, the slide connection comprises two pin 71, each pin 71 being connected to a dedicated rail 21. The rails 21 are aligned and separated by a spacing. The pins 71 are also separated for good stability and better guidance of the control member 7.
La première liaison glissière comporte également au moins un contre-rail 25 parallèle au rail 21 et configuré pour restreindre les mouvements verticaux (selon l'axe X) de l'organe de commande 7. Le contre-rail 25 peut être disposé sur le même élément qu'un tenon 71, ici l'organe de commande 7, comme illustré sur les figures 3 et 4. Dans ce cas, le rail 21 est alors coincé entre le tenon 71 et le contre-rail 25. Cependant il est tout à fait possible d'imaginer un autre cas où le contre-rail 25 peut être disposé sur le même élément qu'un rail 21. Dans ce cas, le tenon 71 est alors disposé entre le rail 21 et le contre-rail 25. Le tenon 71 a de préférence une section en forme de crochet, disposé sur un flanc de l'organe de commande 7 ou sur la paroi latérale interne 22 selon les cas, et dont l'extrémité coulisse dans le rail 21. The first slide connection also comprises at least one counter-rail 25 parallel to the rail 21 and configured to restrict the vertical movements (along the X axis) of the control member 7. The counter rail 25 can be arranged on the same element that a pin 71, here the control member 7, as shown in Figures 3 and 4. In this case, the rail 21 is then wedged between the pin 71 and the counter rail 25. However it is all to it is possible to imagine another case where the counter rail 25 can be arranged on the same element as a rail 21. In this case, the post 71 is then disposed between the rail 21 and the counter rail 25. The post 71 preferably has a hook-shaped section, disposed on a flank of the control member 7 or on the inner side wall 22 as appropriate, and whose end slides in the rail 21.
Dans le cas décrit ci-dessus et illustré au figures 3 à 6 où l'organe de commande 7 comporte deux tenons 71 ainsi qu'un contre rail 25, et où le logement 20 comporte deux rails 21 alignés et séparés, la mise en place dudit organe de commande 7 peut être réalisée selon les étapes suivantes : In the case described above and illustrated in Figures 3 to 6 where the control member 7 comprises two pins 71 and a counter rail 25, and wherein the housing 20 comprises two rails 21 aligned and separated, the establishment of said control member 7 can be performed according to the following steps:
• dans un premier temps l'organe de commande 7 est mis en place dans le logement 20 dans une position dite extrémale où les tenons 71 sont alignés avec les extrémités des rails 21, • dans un deuxième temps, l'organe de commande est translaté de sorte à faire coulisser les tenons 71 contre les rails 21. Les rails 21 sont alors disposés entre les tenons 71 et le contre rail 21. Firstly, the control member 7 is put in place in the housing 20 in a so-called extreme position where the tenons 71 are aligned with the ends of the rails 21, • In a second step, the control member is translated so as to slide the pins 71 against the rails 21. The rails 21 are then disposed between the pins 71 and against the rail 21.
En fonctionnement, la course en translation (selon l'axe Z) de l'organe de commande 7 entraîné par l'actionneur 9, est inférieure à la longueur des rails 21 ce qui l'empêche de ressortir desdits rails 21.  In operation, the travel in translation (along the Z axis) of the control member 7 driven by the actuator 9, is less than the length of the rails 21 which prevents it from emerging from said rails 21.
L'organe de commande 7 peut également comporter une deuxième liaison glissière avec le capot 30 destiné à recouvrir le logement 20. Cette deuxième liaison glissière permet de renforcer le guidage de l'organe de commande 7 et de restreindre ses mouvements latéraux (selon l'axe Y). The control member 7 may also comprise a second sliding connection with the cover 30 intended to cover the housing 20. This second slide connection makes it possible to reinforce the guiding of the control member 7 and to restrict its lateral movements (according to FIG. Y axis).
Cette deuxième liaison glissière peut notamment comporter une rainure 77, parallèle à la première liaison, destinée à recevoir un tenon. Dans l'exemple présenter aux figures 3 et 4, la rainure 77 de la deuxième liaison glissière est disposée sur l'organe de commande 7 et le tenon (non représenté) est quant à lui disposé sur le capot 30, plus précisément sur sa face interne, c'est-à-dire sur sa face venant recouvrir le logement 20.  This second slide connection may in particular comprise a groove 77, parallel to the first connection, intended to receive a tenon. In the example shown in Figures 3 and 4, the groove 77 of the second slide joint is disposed on the control member 7 and the pin (not shown) is in turn disposed on the cover 30, more precisely on its face internal, that is to say on its face from covering the housing 20.
Une telle liaison entre l'organe de commande 7 et le cadre support 5 au sein de l'élément de commande 13 peut être réalisée aussi bien dans le cadre d'un élément de commande 13 comportant un logement 20 ayant son ouverture sur la face avant du cadre support 5 comme décrit ici, mais également pour tout autre type d'élément de commande 13. Such a connection between the control member 7 and the support frame 5 within the control element 13 can be performed both in the context of a control element 13 having a housing 20 having its opening on the front face. of the support frame 5 as described here, but also for any other type of control element 13.
Un tel organe de commande 7 garde constamment un mouvement de translation rectiligne ce qui permet de faire un élément de commande 13 le moins profond possible (selon l'axe X du trièdre). L'actionneur 9, illustré plus en détail sur la figure 7, peut être électrique, comme par exemple un moteur électrique. L'actionneur 9 applique à l'organe de commande 7 un mouvement de translation au moyen du levier 1 1. Cette translation se fait selon l'axe Z du trièdre. L'actionneur 9 peut plus particulièrement comprendre une fiche d'alimentation électrique 91 ainsi qu'un orifice de couplage 92 avec le levier 11. Cet orifice de couplage 92 permet notamment de mettre en rotation le levier 11. Such a control member 7 constantly keeps a rectilinear translational movement which makes it possible to make a control element 13 as shallow as possible (along the X axis of the trihedron). The actuator 9, shown in more detail in FIG. 7, may be electric, such as for example an electric motor. The actuator 9 applies to the control member 7 a translational movement by means of the lever 1 1. This translation is along the Z axis of the trihedron. The actuator 9 may more particularly comprise a power supply plug 91 and a coupling orifice 92 with the lever 11. This coupling orifice 92 makes it possible in particular to rotate the lever 11.
Selon un premier mode de réalisation l'actionneur 9 peut être fixé à l'intérieur du logement 20. Ce premier mode de réalisation est illustré à la figure 8 qui montre l'arrière du logement 20 et plus précisément la face arrière de son fond 29. L'arrière du logement 20 comporte au mois deux premiers orifices 23, disposés sur un plan perpendiculaire au plan formé par les axes Y et Z du trièdre. L'actionneur 9 comporte quant à lui au moins deux deuxièmes orifices 93 de fixations (visibles sur la figure 7) et destinés à venir en regard des premiers orifices 23. La fixation de l'actionneur 9 est réalisée par insertion, depuis l'extérieur du logement 20, d'une barrette 40 comportant au moins deux tiges 41 qui traversent les premiers 23 et deuxièmes 93 orifices.  According to a first embodiment, the actuator 9 can be fixed inside the housing 20. This first embodiment is illustrated in FIG. 8 which shows the rear of the housing 20 and more specifically the rear face of its bottom. The rear of the housing 20 comprises at least two first orifices 23, arranged on a plane perpendicular to the plane formed by the Y and Z axes of the trihedron. The actuator 9 comprises, for its part, at least two second fixing orifices 93 (visible in FIG. 7) intended to come opposite the first orifices 23. The attachment of the actuator 9 is carried out by insertion from the outside. housing 20, a bar 40 having at least two rods 41 which pass through the first 23 and second 93 orifices.
Le logement 20 peut notamment comporter sur la face externe de son fond 29 une cavité 24 destinée à recevoir la barrette 40 pour une meilleure intégration. Cette cavité 24 peut également comporter sur la face interne du fond 29 du logement 20, un creux 26 (visible en négatif sur la figure 8) portant les au moins deux premiers orifices 23 et dans lequel vient s'insérer l'actionneur 9 de sorte que les premiers 23 et deuxièmes 93 orifices soient en regards l'un de l'autre.  The housing 20 may in particular comprise on the outer face of its bottom 29 a cavity 24 for receiving the bar 40 for better integration. This cavity 24 may also comprise on the inner face of the bottom 29 of the housing 20, a recess 26 (visible in negative in FIG. 8) carrying the at least two first orifices 23 and in which the actuator 9 is inserted so that that the first 23 and second 93 orifices are in sight of each other.
La barrette 40 peut également être reliée à la paroi externe du logement 20 et plus précisément à la face externe du fond du logement 20 par une fixation à déformation élastique 44 afin de bloquer les mouvements en translation de ladite barrette 40. Il est néanmoins tout à fait possible d'imaginer d'autres moyens de fixation de l'actionneur 9 dans le logement 20. L'utilisation d'une barrette 40 permet néanmoins un montage rapide ainsi qu'un démontage facilité si besoin. Selon un deuxième mode de réalisation illustré à la figure 9, l'actionneur 9 peut être fixé sur la face interne du capot 30. La fixation de l'actionneur 9 au capot 30 peut être réalisée par n'importe quelle type de fixation par exemple par collage, emboîtage ou au moyen de vis ou rivets. Le capot 30 peut quant à lui être fixé sur le cadre support 5 au dessus de l'ouverture du logement 20 par une fixation à emboîtage élastique, par exemple au moyen d'ergots 55 venant s'emboîter dans des orifices 39 (visibles sur les figures 10 et 11) dédiés sur le capot 30. Une fixation aussi « faible » est possible du fait que l'ouverture du logement 20 et le capot 30 sont disposés sur la face avant du cadre support 5. Ainsi, lors du roulage du véhicule, la pression de l'air vient plaquer le capot 30 contre le cadre support 5 ce qui réduit les contraintes de fixation. The bar 40 can also be connected to the outer wall of the housing 20 and more precisely to the outer face of the bottom of the housing 20 by an elastically deformable attachment 44 to block the translational movement of said bar 40. It is nevertheless quite possible to imagine other means of fixing the actuator 9 in the housing 20. The use of a bar 40 nevertheless allows rapid assembly and easy disassembly if necessary. According to a second embodiment illustrated in FIG. 9, the actuator 9 can be fixed on the inner face of the cover 30. The attachment of the actuator 9 to the cover 30 can be achieved by any type of attachment, for example by gluing, casing or by means of screws or rivets. The cover 30 can in turn be fixed on the support frame 5 above the opening of the housing 20 by an elastically fitting fastening, for example by means of lugs 55 coming to fit into orifices 39 (visible on the Figures 10 and 11) dedicated to the cover 30. Such a "weak" attachment is possible because the opening of the housing 20 and the cover 30 are arranged on the front face of the support frame 5. Thus, during the rolling of the vehicle , the air pressure comes to press the cover 30 against the support frame 5 which reduces the fastening stresses.
Il est néanmoins tout à fait possible d'imaginer tout autre moyen de fixation, par exemple au moyen de vis ou rivets. Le capot 30 peut également recouvrir une rangée de paliers 51. De ce fait, lorsque les volets 3 sont installés et que les axes de pivotement A sont insérés dans les paliers 51, le capot 30 peut maintenir une extrémité des volets 3.  It is nevertheless quite possible to imagine any other means of attachment, for example by means of screws or rivets. The cover 30 may also cover a row of bearings 51. Therefore, when the shutters 3 are installed and the pivot pins A are inserted in the bearings 51, the cover 30 can hold one end of the shutters 3.
Afin de maintenir les volets 3 dans les paliers 51 au niveau des montants latéraux 5b du cadre support 5, notamment au niveau des paliers non recouverts par le capot 30, le dispositif d'obturation 1 peut comporter au moins un élément de blocage 60, comme illustré sur les figures 2, 10 et 11. Cet élément de blocage 60 recouvre une rangée de palier 51 et maintien les axes de pivotement A des volets 3 dans lesdits paliers 51. In order to maintain the shutters 3 in the bearings 51 at the level of the lateral uprights 5b of the support frame 5, in particular at the level of the bearings not covered by the cover 30, the closure device 1 may comprise at least one blocking element 60, such as illustrated in Figures 2, 10 and 11. This locking element 60 covers a bearing row 51 and maintaining the pivot axes A flaps 3 in said bearings 51.
L'élément de blocage 60 peut ainsi être une bande rigide fixée sur le cadre support 5. Pour cette fixation au cadre support, l'élément de blocage 60 peut comporter au moins un organe de liaison 61 faisant sailli dudit élément de blocage 60. Cet organe de liaison 61 comporte plus particulièrement une base le reliant audit élément de blocage 60 et une tête de largeur supérieure à ladite base. De préférence, l'organe de liaison 61 à une forme générale en T. The locking element 60 may thus be a rigid band fixed on the support frame 5. For this attachment to the support frame, the locking element 60 may comprise at least one connecting member 61 projecting from said locking element 60. connecting member 61 more particularly comprises a base connecting it to said locking element 60 and a head of greater width than said base. Preferably, the connecting member 61 has a general shape T.
De façon complémentaire, le montant latéral 5b comporte, sur sa face comprenant la au moins une rangée de palier 51, au moins une rainure 52 débouchant sur un coté extérieur dudit montant latéral 5b. Cette rainure 52 est de forme complémentaire à l'organe de liaison 61. Comme illustré sur la figure 11, les organes de liaison 61 viennent s'insérer dans les rainures 52 pour maintenir les volets 3.  In a complementary manner, the lateral upright 5b comprises, on its face comprising the at least one bearing row 51, at least one groove 52 opening on an outer side of said lateral upright 5b. This groove 52 is of complementary shape to the connecting member 61. As illustrated in FIG. 11, the connecting members 61 are inserted into the grooves 52 to hold the shutters 3.
L'élément de blocage 60 est de préférence fixé sur le cadre support 5 comprenant la rangée de palier 51 afin qu'il ne se dégage pas des rainures 52. Cette fixation peut être réalisée par une fixation à emboîtage élastique. Cette fixation à emboîtage élastique peut notamment comporter une languette élastique 70 dont une première extrémité comporte un embout faisant sailli vers l'extérieur du cadre support 5 et dont une deuxième extrémité est reliée audit cadre support 5. Cet embout est destiné à venir s'insérer dans une ouverture 62 ménagée dans l'élément de blocage 60. Cet embout comporte plus particulièrement un chanfrein permettant l'assemblage par translation de l'élément de blocage 60 sur le montant latéral 5b en déformant la languette élastique 70 jusqu'à l'insertion de l'embout dans l'ouverture 62. L'embout comporte également une surface plane, opposée au chanfrein et qui fait obstacle en translation au démontage de l'élément de blocage 60 du montant latéral. Il est tout à fait possible également d'imaginer une fixation à emboîtage élastique inverse où la languette élastique 70 et son embout sont disposés sur l'élément de blocage 60 et où l'embout est destiné à venir s'insérer dans une ouverture ménagée dans le cadre support 5. The locking element 60 is preferably fixed on the support frame 5 comprising the bearing row 51 so that it does not disengage the grooves 52. This attachment can be achieved by an elastically fitting fastener. This fastening with elastic casing may include in particular an elastic tongue 70, a first end has a tip projecting outwardly of the support frame 5 and a second end is connected to said support frame 5. This endpiece is intended to be inserted in an opening 62 formed in the locking element 60. This tip more particularly comprises a chamfer allowing the translation assembly of the locking element 60 on the lateral upright 5b by deforming the elastic tongue 70 until insertion. The tip also has a flat surface, opposite the chamfer and which is a barrier in translation to the disassembly of the locking element 60 of the lateral upright. It is quite possible also to imagine a fastening with reverse elastic casing where the elastic tongue 70 and its tip are arranged on the locking element 60 and where the end piece is intended to be inserted into an opening in the support frame 5.
La mise en place de l'élément de blocage 60 est réalisée après le montage des volets 3 sur le cadre support 5. Cette mise en place consiste tout d'abord à mettre en regard l'au moins un organe de liaison 61 de l'élément de blocage 60 avec l'au moins une rainure 52 du cadre support 5. Ensuite, l'élément de blocage 60 est translaté de sorte que l'au moins un organe de liaison 61 s'insère dans l'au moins une rainure 52 et de sorte que l'élément de blocage 60 recouvre la rangée de paliers 51. The establishment of the blocking element 60 is carried out after the flaps 3 are mounted on the support frame 5. This installation consists first of all in facing the at least one connecting member 61 of the locking element 60 with the at least one groove 52 of the support frame 5. Then, the locking element 60 is translated so that the at least one connecting member 61 is inserted into the at least one groove 52 and that the blocking member 60 covers the row of bearings 51.
Une telle fixation des volets 3 au moyen d'un tel élément de blocage 60 permet un montage simplifié et rapide du dispositif d'obturation 1 car il ne nécessite pas l'utilisation d'outils spécifiques pour assurer le maintien des volets 3 dans les paliers 51. De plus une telle fixation reste réversible sans endommager le cadre support 5, les volets 3 ou l'élément de blocage 60 lui même. Cela est avantageux en cas de réparation à effectuer sur le dispositif d'obturation 1. Such fastening flaps 3 by means of such a locking member 60 allows a simplified and fast mounting of the closure device 1 because it does not require the use of specific tools to maintain the shutters 3 in the bearings 51. Moreover, such a fastening remains reversible without damaging the support frame 5, the flaps 3 or the blocking element 60 itself. This is advantageous in case of repair to be performed on the shutter device 1.
Une telle fixation des volets 3 peut être réalisée aussi bien dans le cadre d'un dispositif d'obturation 1 dont la au moins une rangée de paliers 51 est réalisée sur la face avant du cadre support 5 comme décrit ici, mais également pour tout autre type de dispositif d'obturation 1.  Such fastening flaps 3 can be performed both in the context of a closure device 1 whose at least one row of bearings 51 is formed on the front face of the support frame 5 as described here, but also for any other type of shutter device 1.
Comme illustré sur les figures 2, 3, et 10, les volets 3 peuvent comporter des flasques 35 à leurs extrémités. De façon complémentaire, l'élément de blocage 60 peut quand à lui comporter des joues 65 semi-sphériques venant recouvrir les flasques 35 des volets 3, plus particulièrement au niveau des extrémités et des axes de pivotement A des volets 3 que ledit élément de blocage 60 maintien. De même, le capot 30 peut lui également comporter des joues 36 semi-sphériques venant recouvrir les flasques 35 des volets 3, plus particulièrement au niveau des extrémités et des axes de pivotement A des volets 3 que ledit capot recouvre. Ces flasques 35 et ces joues 65, 36 semi-sphériques forment une barrière de protection qui réduit la quantité de poussière et débris qui pourraient arriver au niveau des paliers 51 et à l'intérieure du logement 20 et qui pourraient gripper le pivotement des volets 3. As illustrated in Figures 2, 3, and 10, the flaps 3 may include flanges 35 at their ends. In a complementary manner, the blocking element 60 may, when it has it, include semi-spherical cheeks 65 coming to cover the flanges 35 of the flaps 3, more particularly at the ends and the pivot axes A flaps 3 that said locking member 60 holds. Similarly, the cover 30 may also include semi-spherical cheeks 36 coming to cover the flanges 35 of the flaps 3, more particularly at the ends and pivoting axes A flaps 3 that said cover covers. These flanges 35 and these cheeks 65, 36 semi-spherical form a protective barrier which reduces the amount of dust and debris that could occur at the bearings 51 and inside the housing 20 and that could seize the pivoting of the flaps 3 .
La présente invention concerne également un procédé de fabrication d'un dispositif d'obturation 1 pour entrée d'air de face avant de véhicule automobile tel que décrit précédemment.

• une troisième sous-étape de mise en place et de fixation du au moins un élément de blocage 60.  A third sub-step of placing and fixing the at least one blocking element 60.
Ainsi, on voit bien que du fait que le cadre support 5 comporte un logement 20 dont l'ouverture est dirigée vers l'avant du véhicule, permet un meilleur accès aux éléments du dispositif de commande 13 dans le cadre d'une intervention ou d'une réparation. De plus le fait que les volets 3 soient également montés par l'avant simplifie leur maintien contre le cadre support 5. Thus, it is clear that because the support frame 5 comprises a housing 20 whose opening is directed towards the front of the vehicle, allows better access to the elements of the control device 13 in the context of an intervention or d 'a repair. Moreover the fact that the flaps 3 are also mounted by the front simplifies their maintenance against the support frame 5.
