Description

La présente invention concerne un dispositif aérodynamique pour unThe present invention relates to an aerodynamic device for a

véhicule automobile. L'invention concerne également un feu de signalisation pour un véhicule automobile et un véhicule automobile équipés d'un tel dispositif 5 aérodynamique. Les véhicules automobiles couramment utilisés sont de plus en plus équipés d'éléments améliorant leur aérodynamisme. La majorité de ces éléments sont fixes et permanents si bien qu'ils impactent donc fortement sur le style du véhicule, réduisant de ce fait la liberté de créativité des stylistes. 10 On connaît également des dispositifs aérodynamiques qui sont mobiles et qui permettent de modifier le comportement du véhicule à une certaine vitesse ou dans certaines conditions afin d'augmenter sa stabilité. Ainsi, les véhicules automobiles sont équipés de volets ou d'ailerons déplaçables par des moyens d'entraînement entre une position 15 escamotée dans un élément de carrosserie et une position active en saillie par rapport à cet élément de carrosserie. Mais, le principal inconvénient de ce genre de dispositif aérodynamique réside dans leur intégration dans la carrosserie du véhicule. En effet, les moyens d'entraînement des volets ou des ailerons 20 sont complexes et présentent généralement un volume important si bien que ce genre de dispositif aérodynamique ne peut être disposé sur des éléments de carrosserie ayant un volume vide restreint par exemple au-dessous. Or, dans certains cas, pour augmenter la stabilité du véhicule, les constructeurs de véhicules souhaitent intégrer des dispositifs aérodynamiques 25 escamotables à des emplacements où l'élément de carrosserie ne dispose pas au-dessous d'un volume vide important. En effet, l'une des zones les plus efficaces d'un point de vue aérodynamique, pour implanter un dispositif aérodynamique, est la zone arrière, proche de la jonction de la fin du côté de la caisse du véhicule et de la lunette 30 arrière. L'invention a donc pour but de proposer un dispositif aérodynamique qui permet de réduire les efforts aérodynamiques et ainsi de proposer des véhicules automobiles très performants en aérodynamique, tout en libérant le style de certaines contraintes aérodynamiques et qui est facilement intégrable sur un élément de carrosserie d'un véhicule automobile. L'invention a pour objet un dispositif aérodynamique pour un véhicule automobile comprenant des feux de signalisation disposés sur un élément de carrosserie de la partie arrière dudit véhicule, caractérisé en ce qu'au moins un des feux de signalisation comporte au moins une partie mobile déplaçable en translation par des moyens de commande entre une position escamotée et une position active en saillie par rapport à l'élément de carrosserie.  motor vehicle. The invention also relates to a signaling light for a motor vehicle and a motor vehicle equipped with such an aerodynamic device. Commonly used motor vehicles are increasingly equipped with elements improving their aerodynamics. The majority of these elements are fixed and permanent so that they have a strong impact on the style of the vehicle, thereby reducing designers' freedom of creativity. Aerodynamic devices are also known which are movable and which make it possible to modify the behavior of the vehicle at a certain speed or under certain conditions in order to increase its stability. Thus, the motor vehicles are equipped with flaps or fins movable by drive means between a position 15 retracted in a bodywork element and an active position projecting from this bodywork element. But, the main disadvantage of this kind of aerodynamic device lies in their integration into the vehicle body. Indeed, the drive means of the flaps or fins 20 are complex and generally have a large volume so that this kind of aerodynamic device can not be arranged on bodywork elements having a restricted volume volume for example below. In some cases, however, to increase the stability of the vehicle, vehicle manufacturers wish to incorporate retractable aerodynamic devices at locations where the body member does not have a large empty space. Indeed, one of the most aerodynamically efficient areas for implanting an aerodynamic device is the rear area, close to the end junction of the vehicle body side and the rear window. . The object of the invention is therefore to propose an aerodynamic device which makes it possible to reduce the aerodynamic forces and thus to propose high performance aerodynamic motor vehicles, while at the same time releasing the style of certain aerodynamic constraints and which is easily integrable on a bodywork element. of a motor vehicle. The subject of the invention is an aerodynamic device for a motor vehicle comprising signaling lamps arranged on a bodywork element of the rear part of said vehicle, characterized in that at least one of the signaling lamps comprises at least one mobile movable part. in translation by control means between a retracted position and an active position projecting from the bodywork element.

Dans la description qui suit, les orientations utilisées sont les orientations habituelles d'un véhicule automobile et les termes "avant" et "arrière" s'entendent par rapport au sens de la marche normale de ce véhicule. Sur les Figs. 1 et 2, on a représenté schématiquement une partie arrière d'un véhicule automobile 1 et qui comprend, entre autres, un pavillon 2, un côté 3 et un panneau de coffre 4 qui est, dans l'exemple de réalisation représenté sur ces figures, constitué par un hayon muni d'une lunette arrière 5. Ainsi que montré sur ces figures, l'élément de carrosserie sur lequel est implanté un dispositif aérodynamique conforme à l'invention, est formé par un panneau 6 disposé entre la fin du côté 3 de la carrosserie et la lunette arrière 5. Dans l'exemple de réalisation représenté sur ces figures, le panneau 6 situé de chaque côté 3 du véhicule est équipé d'un dispositif aérodynamique, chacun de ces panneaux pouvant être équipé d'un tel dispositif aérodynamique. Comme montré sur les Figs. 1 et 2, la partie arrière du véhicule est équipé, de chaque côté de la lunette arrière 5, d'un feu de signalisation désigné par la référence générale 10. Chaque feu de signalisation 10 comprend un premier élément 20 fixe et un second élément 30 qui constitue le dispositif aérodynamique conforme à l'invention. Ce dispositif aérodynamique 30, représenté sur les Figs. 1 à 3 et qui forme un sous ensemble du feu de signalisation 10, comprend au moins une partie mobile 31 déplaçable par translation par des moyens de commande entre une position escamotée (Fig. 1) et une position active en saillie (Fig. 2) par rapport à l'élément de carrosserie 6. Ainsi que montré sur les Figs. 3 à 5, la partie mobile 31 est montée dans un boîtier 32 muni d'un logement 33 de forme sensiblement complémentaire au pourtour de la partie mobile 31. Le boîtier 32 est fixé dans un évidement ménagé dans le panneau 6 au moyen d'organes de fixation appropriés, comme par exemple des organes de vissage, non représentés. Les moyens de commande du déplacement de la partie mobile 31 sont disposés dans le logement 33 du boîtier 32 et comprennent au moins un pignon 35 et, de préférence, comme montré à la Fig. 4, deux pignons 35 montés chacun sur des pattes d'accrochage 35a. Chaque pignon 35 est entraîné en rotation par un câble de transmission 36 relié à un réducteur 38 actionné par un moteur électrique 37. Les moyens de commande comprennent également au moins une crémaillère 40 et, de préférence deux crémaillères 40 (Fig. 5) portées par la partie mobile 31 et destinées chacune à coopérer avec un pignon 35. Chaque crémaillère 40 s'étend dans la direction de déplacement de la partie mobile 31. Des moyens de guidage équipent également la partie mobile 31 et le boîtier 32 et ces moyens de guidage son formés par au moins une tige 41 portée par la partie mobile 31 et de préférence par deux tiges 41 destinées à coopérer chacune avec un plot 42 porté par le boîtier 32.  In the description that follows, the orientations used are the usual orientations of a motor vehicle and the terms "front" and "rear" refer to the direction of normal operation of this vehicle. In Figs. 1 and 2, there is shown schematically a rear portion of a motor vehicle 1 and which comprises, inter alia, a roof 2, a side 3 and a trunk panel 4 which is, in the embodiment shown in these figures constituted by a tailgate provided with a rear window 5. As shown in these figures, the bodywork element on which is implanted an aerodynamic device according to the invention, is formed by a panel 6 disposed between the end of the side 3 of the body and the rear window 5. In the embodiment shown in these figures, the panel 6 located on each side 3 of the vehicle is equipped with an aerodynamic device, each of these panels can be equipped with such a device. aerodynamic device. As shown in Figs. 1 and 2, the rear part of the vehicle is equipped on each side of the rear window 5 with a signaling light designated by the general reference 10. Each signaling light 10 comprises a first fixed element and a second element 30. which constitutes the aerodynamic device according to the invention. This aerodynamic device 30, shown in Figs. 1 to 3 and which forms a subset of the signal light 10, comprises at least one movable portion 31 movable by translation by control means between a retracted position (FIG 1) and an active position protruding (FIG 2). relative to the bodywork member 6. As shown in Figs. 3 to 5, the movable portion 31 is mounted in a housing 32 provided with a housing 33 of substantially complementary shape to the periphery of the movable portion 31. The housing 32 is fixed in a recess in the panel 6 by means of organs suitable fasteners, such as, for example, screwing members, not shown. The means for controlling the displacement of the movable portion 31 are arranged in the housing 33 of the housing 32 and comprise at least one pinion 35 and, preferably, as shown in FIG. 4, two pinions 35 each mounted on hooking tabs 35a. Each pinion 35 is rotated by a transmission cable 36 connected to a gearbox 38 actuated by an electric motor 37. The control means also comprise at least one rack 40 and preferably two racks 40 (FIG 5) carried by the movable portion 31 and each intended to cooperate with a pinion 35. Each rack 40 extends in the direction of movement of the movable portion 31. Guiding means also equip the movable portion 31 and the housing 32 and these guide means its formed by at least one rod 41 carried by the movable portion 31 and preferably by two rods 41 intended to cooperate each with a stud 42 carried by the housing 32.

Chaque plot 42 comporte un orifice 43 de forme complémentaire à la tige 41 et dans lequel est guidée cette tige 41. Comme montré sur les Figs. 6 et 7, un organe élastique 45 monté sur chaque plot 41 assure le rattrapage du jeu de fonctionnement entre chaque crémaillère 40 et le pignon 35 associé.. Une bague 46 est montée sur chaque tige 41 de façon à former une butée lors du déplacement de la partie mobile 31. Lorsque le moteur électrique 37 est actionné, le réducteur 38 entraîne en rotation les pignons 35 au moyen des câbles 36. La rotation de ces pignons 35 provoque le déplacement des crémaillères 40 ce qui entraîne la translation de la partie mobile 31 et son déplacement entre sa position escamotée (Fig. 1) et sa position active en saillie (Fig. 2). Lors de ces déplacements, la partie mobile 31 est guidée par les tiges 41 qui coulissent chacune dans un orifice 43 d'un plot 42. Le déplacement de cette partie mobile 31 est limité par les bagues 46, ainsi que montré à la Fig. 7. Pour ramener la partie mobile 31 dans sa position escamotée, le moteur électrique 37 actionne en sens inverse le réducteur 38 et les pignons 35 par l'intermédiaire des câbles 36.  Each stud 42 has an orifice 43 of complementary shape to the rod 41 and in which is guided this rod 41. As shown in FIGS. 6 and 7, an elastic member 45 mounted on each stud 41 ensures the clearance of the operating clearance between each rack 40 and the associated gear 35. A ring 46 is mounted on each rod 41 so as to form a stop during the movement of the moving part 31. When the electric motor 37 is actuated, the gearbox 38 rotates the pinions 35 by means of the cables 36. The rotation of these pinions 35 causes the movement of the racks 40 which causes the translation of the movable part 31 and its movement between its retracted position (Fig. 1) and its active projecting position (Fig. 2). During these displacements, the movable portion 31 is guided by the rods 41 which each slide in an orifice 43 of a stud 42. The displacement of this movable portion 31 is limited by the rings 46, as shown in FIG. 7. To bring the moving part 31 back into its retracted position, the electric motor 37 actuates the gearbox 38 and the pinions 35 in the opposite direction by means of the cables 36.

Le déploiement du ou des parties mobiles 31 dont l'arrière du véhicule automobile 1 est équipé, peut être actionné et piloté par au moins un organe de commande en fonction d'informations fournies par exemple par un capteur relié à 'la colonne de direction du véhicule et/ou par un capteur de pression et/ou de vitesse et/ou de frottements implanté sur la carrosserie du véhicule. Le feu de signalisation forme donc un ensemble compact et peu encombrant qui est facilement implantable sur les éléments de la carrosserie du véhicule. Le dispositif aérodynamique selon l'invention permet d'améliorer l'aérodynamique des véhicules, tout en étant aussi discret que possible afin de laisser aux stylistes une plus grande liberté.  The deployment of the movable part or parts 31, the rear of the motor vehicle 1 is equipped, can be actuated and controlled by at least one control member according to information provided for example by a sensor connected to the steering column of the vehicle. vehicle and / or by a pressure sensor and / or speed and / or friction implanted on the vehicle body. The traffic light thus forms a compact and space-saving assembly that is easily implantable on the elements of the vehicle body. The aerodynamic device according to the invention makes it possible to improve the aerodynamics of the vehicles, while being as discreet as possible in order to give stylists greater freedom.

6 Ce dispositif aérodynamique permet d'améliorer les performances des véhicules dont la silhouette est déjà optimisée ce qui permet d'avoir des véhicules aux formes "standards", mais avec des performances aérodynamiques supérieures.5  6 This aerodynamic device improves the performance of vehicles whose silhouette is already optimized which allows vehicles with "standard" shapes, but with superior aerodynamic performance.
