Description

TITRE : Agencement pour véhicule comprenant un dispositif de support d’au moins un composant équipant la structure avant du véhicule TITLE: Arrangement for a vehicle comprising a support device for at least one component fitted to the front structure of the vehicle
L’invention concerne un agencement pour véhicule comprenant un dispositif de support configuré pour supporter au moins un composant à équiper dans la structure avant du véhicule. L’invention concerne également un dispositif de support destiné à un tel agencement. L’invention concerne encore un véhicule équipé d’un agencement et/ou un dispositif de support selon l’invention. L’invention concerne enfin un procédé de montage d’un agencement selon l’invention. The invention relates to an arrangement for a vehicle comprising a support device configured to support at least one component to be fitted in the front structure of the vehicle. The invention also relates to a support device intended for such an arrangement. The invention also relates to a vehicle equipped with an arrangement and/or a support device according to the invention. The invention finally relates to a method of mounting an arrangement according to the invention.
Dans le milieu automobile, l’évolution des véhicules depuis des motorisations traditionnelles, à moteur thermique, vers des motorisations électriques ou hybrides s’est accompagnée d’une augmentation considérable de leur masse du fait de la présence de batteries de propulsion, ou batteries de motricité. Il en résulte que les structures de caisse, conçues pour des véhicules thermiques, ne peuvent pas être utilisées à l’identique pour produire des véhicules à motorisation hybride ou électrique sans dégrader les prestations offertes par le véhicule en matière de sécurité. En effet, l’énergie à absorber en cas de choc frontal est d’autant plus importante que la masse du véhicule augmente et un accroissement des efforts peut être constaté lors d’un choc frontal. In the automotive sector, the evolution of vehicles from traditional engines, with thermal engines, to electric or hybrid engines has been accompanied by a considerable increase in their mass due to the presence of propulsion batteries, or power batteries. motor skills. The result is that body structures, designed for thermal vehicles, cannot be used identically to produce vehicles with hybrid or electric engines without degrading the safety benefits offered by the vehicle. Indeed, the energy to be absorbed in the event of a frontal impact is greater as the mass of the vehicle increases and an increase in forces can be observed during a frontal impact.
Dans le cas de véhicules à motorisation thermique, il est connu de renforcer la structure avant du véhicule au moyen de pièces de renfort, tel que des tirants, vissées sur le berceau et la structure de caisse afin de palier un manque de rigidité de la structure avant. Un tel agencement n’est néanmoins pas suffisant pour prévenir des déformations de la structure avant du véhicule dans le cas de véhicules à motorisation électrique ou hybride, d’une part du fait de l’augmentation de leur masse et d’autre part parce qu’ils sont inadaptés à la protection des systèmes électriques haut voltage. En outre, la transition vers des motorisations électrique ou hybride s’accompagne d’une nécessité de réaménagement de la structure avant des véhicules afin d’intégrer des composants additionnels mais également d’assurer la protection des différents systèmes et interfaces présents, tels que les systèmes hydrauliques, impliqués dans le traitement thermiques des batteries de propulsion et/ou de l’habitacle, et les systèmes électriques, notamment d’alimentation haut voltage alimentant les batteries de propulsion. In the case of vehicles with thermal engines, it is known to reinforce the front structure of the vehicle by means of reinforcing parts, such as tie rods, screwed to the cradle and the body structure in order to compensate for a lack of rigidity of the structure Before. Such an arrangement is nevertheless not sufficient to prevent deformation of the front structure of the vehicle in the case of vehicles with electric or hybrid engines, on the one hand due to the increase in their mass and on the other hand because They are unsuitable for the protection of high voltage electrical systems. In addition, the transition to electric or hybrid engines is accompanied by a need to reorganize the front structure of vehicles in order to integrate additional components but also to ensure the protection of the various systems and interfaces present, such as the hydraulic systems, involved in the heat treatment of the propulsion batteries and/or the passenger compartment, and the electrical systems, in particular high voltage power supply powering the propulsion batteries.
Il est connu d’équiper la structure avant des véhicules de supports, configurés pour supporter différents composants équipant la face avant. De tels supports sont classiquement montés sur le berceau et/ou la structure de caisse du véhicule, par exemple par fixation sur des pièces de renfort et/ou de tirants. De tels agencements s’accompagnent néanmoins d’une démultiplication des références et, par extension, d’une augmentation de la dispersion et de la chaîne de côtes. En outre, les interventions sur le véhicule, par exemple dans le cadre du remplacement ou de la réparation d’un composant ou système situé en face avant, peuvent s’avérer complexes et chronophages en ce qu’elles peuvent nécessiter l’extraction de systèmes et composants ne nécessitant pas d’intervention spécifique mais entravant l’accès au composant ou système ciblé. It is known to equip the front structure of vehicles with supports, configured to support different components fitted to the front face. Such supports are conventionally mounted on the cradle and/or the body structure of the vehicle, for example by fixing to reinforcement parts and/or tie rods. Such arrangements are nevertheless accompanied by a multiplication of references and, by extension, an increase in dispersion and the chain of coasts. In addition, interventions on the vehicle, for example in the context of replacing or repairing a component or system located on the front panel, can prove to be complex and time-consuming in that they may require the extraction of systems. and components not requiring specific intervention but hindering access to the targeted component or system.

D’autres détails, caractéristiques et avantages ressortiront plus clairement à la lecture de la description détaillée donnée ci-après, à titre indicatif et non limitatif, en relation avec les différents exemples de réalisation illustrés sur la figure suivante : Other details, characteristics and advantages will emerge more clearly on reading the detailed description given below, for information only and not limitation, in relation to the different examples of embodiment illustrated in the following figure:
La figure 1 est une représentation schématique simplifiée vue de dessous d’un agencement selon l’invention, comprenant un dispositif de support. Figure 1 is a simplified schematic representation seen from below of an arrangement according to the invention, comprising a support device.
La figure 2 est une représentation schématique d’une partie de l’agencement vu de dessus. Figure 2 is a schematic representation of part of the arrangement seen from above.
La figure 3 est une représentation schématique en perspective d’une partie de l’agencement. Figure 3 is a schematic perspective representation of part of the arrangement.
La figure 1 illustre schématiquement un exemple de réalisation d’un agencement 1 selon l’invention disposé au niveau de la structure avant d’un véhicule 2, notamment d’un véhicule 2 automobile. Le véhicule 2 considéré est particulièrement un véhicule 2 automobile à motorisation électrique. De manière alternative, l’agencement 1 selon l’invention peut s’appliquer mutatis mutandis aux véhicules 2 à motorisation thermique comprenant un moteur thermique ou aux véhicules 2 à motorisation hybride comprenant un moteur thermique et au moins une batterie de propulsion, aussi qualifiée de batterie de motricité. Ledit véhicule 2 peut, par exemple, être un véhicule particulier ou un véhicule utilitaire. Figure 1 schematically illustrates an exemplary embodiment of an arrangement 1 according to the invention arranged at the front structure of a vehicle 2, in particular a motor vehicle 2. The vehicle 2 considered is particularly an automobile vehicle 2 with an electric motor. Alternatively, the arrangement 1 according to the invention can be applied mutatis mutandis to vehicles 2 with a thermal engine comprising a thermal engine or to vehicles 2 with a hybrid engine comprising a thermal engine and at least one propulsion battery, also referred to as motor skills battery. Said vehicle 2 can, for example, be a private vehicle or a utility vehicle.
Les figures 1 à 3 illustrent un exemple de réalisation de l’agencement 1 selon l’invention. Par convention dans la description ci-après, la direction selon laquelle le véhicule 2 automobile se déplace en ligne droite est définie comme étant la direction longitudinale X. La direction perpendiculaire à la direction longitudinale et située dans un plan parallèle au sol est nommée direction transversale Y. La direction perpendiculaire aux directions X et Y est nommée direction verticale Z. Ainsi, on définit un repère direct XYZ représenté sur la figure 1 , classiquement mis en œuvre dans le milieu automobile. Les termes « haut » et « bas » ou « supérieur » et « inférieur » s’entendent dans leur sens général, les termes « bas » et « inférieur » désignant une proximité avec le sol plus importante. Egalement, les termes « premier », « deuxième » ont vocation à distinguer des éléments similaires et non à définir une hiérarchie au sein desdits éléments. Figures 1 to 3 illustrate an exemplary embodiment of arrangement 1 according to the invention. By convention in the description below, the direction in which the automobile vehicle 2 moves in a straight line is defined as being the longitudinal direction figure 1, classically implemented in the automotive sector. The terms “high” and “low” or “upper” and “lower” are understood in their general sense, the terms “low” and “lower” designating greater proximity to the ground. Also, the terms “first”, “second” are intended to distinguish similar elements and not to define a hierarchy within said elements.
De manière générale, l’agencement 1 selon l’invention comprend un berceau 3, une structure de caisse 4 et un dispositif de support 5 configuré pour supporter au moins un composant 6 à équiper dans la structure avant du véhicule 2. Generally speaking, the arrangement 1 according to the invention comprises a cradle 3, a body structure 4 and a support device 5 configured to support at least one component 6 to be fitted in the front structure of the vehicle 2.
On entend notamment par « structure de caisse » des éléments classiques de structure de caisse 4 tels que des longerons, des traverses ou des brancards équipant classiquement les véhicules 2. By “body structure” is meant in particular conventional elements of body structure 4 such as spars, crosspieces or stretchers conventionally fitted to vehicles 2.
De manière générale, le dispositif de support 5 comprend au moins un corps 7, une paire de tirants 8 et une traverse 9. On entend notamment par « tirant » un élément de renfort et/ou de liaison. Il est entendu que, dans l’ensemble de la description ci-après, toute caractéristique décrite relativement au dispositif de support 5 compris dans l’agencement 1 selon l’invention peut également s’étendre à un dispositif de support 5, en tant que tel, pour une utilisation dans un agencement 1 et/ou dans un véhicule 2 selon l’invention. Generally speaking, the support device 5 comprises at least one body 7, a pair of tie rods 8 and a crosspiece 9. The term “tie rod” means in particular a reinforcing and/or connecting element. It is understood that, throughout the description below, any characteristic described in relation to the support device 5 included in the arrangement 1 according to the invention can also extend to a support device 5, as such, for use in an arrangement 1 and/or in a vehicle 2 according to the invention.
Le corps 7 est plan et est configuré pour supporter au moins un composant 6 équipé dans la structure avant du véhicule 2. Notamment, tel qu’illustré, le composant 6 considéré peut être un boîtier de chauffage, notamment du type CTP, c’est-à-dire à Coefficient Positif de Température. Un tel boîtier de chauffage peut notamment être destiné au traitement thermique de l’habitacle du véhicule 2. En outre, ledit composant 6 peut être compris dans l’agencement 1 selon l’invention. The body 7 is planar and is configured to support at least one component 6 equipped in the front structure of the vehicle 2. In particular, as illustrated, the component 6 considered can be a heating box, in particular of the CTP type, it is i.e. Positive Temperature Coefficient. Such a heating box may in particular be intended for the heat treatment of the vehicle passenger compartment 2. In addition, said component 6 can be included in arrangement 1 according to the invention.
Afin de permettre la fixation du composant 6 considéré, le corps 7 comprend au moins un moyen de fixation 71. De manière préférentielle, le corps 7 comprend une pluralité desdits moyens de fixation 71. Par exemple, le corps 7 peut comprendre des moyens de fixation 71 du type clip et/ou vis. In order to allow the fixing of the component 6 considered, the body 7 comprises at least one fixing means 71. Preferably, the body 7 comprises a plurality of said fixing means 71. For example, the body 7 may comprise fixing means 71 of the clip and/or screw type.
Dans l’exemple particulier illustré, le corps 7 présente une forme sensiblement rectangulaire dans laquelle un côté proximal est relié à la traverse 9 et est configuré pour présenter, le long de la direction longitudinale, la plus grande proximité avec le berceau 3 au sein de l’agencement 1. La forme rectangulaire comprend, en outre, un côté distal, opposé au côté proximal le long de la direction longitudinale, et deux côté latéraux, reliant le côté proximal et le côté distal entre eux. In the particular example illustrated, the body 7 has a substantially rectangular shape in which a proximal side is connected to the crosspiece 9 and is configured to present, along the longitudinal direction, the greatest proximity to the cradle 3 within arrangement 1. The rectangular shape further comprises a distal side, opposite the proximal side along the longitudinal direction, and two lateral sides, connecting the proximal side and the distal side together.
La paire de tirants 8 est configurée pour être fixée sur le berceau 3 d’une part et sur la structure de caisse 4 d’autre part. Les tirants 8 sont reliés au corps 7 par l’intermédiaire de la traverse 9. En outre, les tirants 8 sont reliés entre eux par l’intermédiaire de cette même traverse 9 de sorte à assurer la rigidité du dispositif de support 5 le long de la direction transversale Y lorsque l’agencement 1 est équipé au sein du véhicule 2. Il est entendu que, dans l’ensemble de la description ci-après, toute description faite en référence à l’un des tirants 8 peut s’étendre à l’ensemble des tirants 8 de la paire. The pair of tie rods 8 is configured to be fixed on the cradle 3 on the one hand and on the body structure 4 on the other hand. The tie rods 8 are connected to the body 7 via the crosspiece 9. In addition, the tie rods 8 are connected to each other via this same crosspiece 9 so as to ensure the rigidity of the support device 5 along the transverse direction Y when the arrangement 1 is equipped within the vehicle 2. It is understood that, throughout the description below, any description made with reference to one of the tie rods 8 can extend to all the tie rods 8 of the pair.
Le tirant 8 présente la forme d’une pièce allongée, notamment au moins en partie rectiligne, présentant deux extrémités. Le tirant 8 est notamment relié à la traverse 9 au niveau d’une première extrémité 81 tandis qu’une deuxième extrémité 82, opposée, s’étend vers l’arrière du véhicule 2. En l’espèce, la deuxième extrémité 82 du tirant 8 est une extrémité libre configurée pour être fixée sur la structure de caisse 4, par exemple à une traverse avant de de la structure de caisse 4, non représentée, notamment une traverse avant de plancher. Notamment, la traverse 9 est configurée pour s’étendre transversalement, ou sensiblement transversalement, au sein du véhicule 2, c’est-à-dire parallèlement à la direction transversale Y. Le tirant 8 s’étend transversalement à la traverse 9, c’est-à-dire le long d’une droite sécante à une direction d’extension de ladite traverse 9. De manière préférentielle, le tirant 8 s’étend vers l’arrière du véhicule 2 le long d’une direction distincte de la direction longitudinale X de sorte qu’il forme un angle non-droit relativement à la traverse 9, notamment en direction de l’extérieur du véhicule 2 le long de la direction transversale Y. The tie rod 8 has the shape of an elongated part, in particular at least partly rectilinear, having two ends. The tie rod 8 is in particular connected to the crosspiece 9 at a first end 81 while a second end 82, opposite, extends towards the rear of the vehicle 2. In this case, the second end 82 of the tie rod 8 is a free end configured to be fixed to the body structure 4, for example to a front cross member of the body structure 4, not shown, in particular a front cross member of floor. In particular, the crosspiece 9 is configured to extend transversely, or substantially transversely, within the vehicle 2, that is to say parallel to the transverse direction Y. The tie rod 8 extends transversely to the crosspiece 9, c that is to say along a straight line intersecting a direction of extension of said crossmember 9. Preferably, the tie rod 8 extends towards the rear of the vehicle 2 along a direction distinct from the longitudinal direction
Le tirant 8 présente également, de manière préférentielle, la forme d’un profilé. Notamment, le tirant 8 présente, le long de la direction verticale Z, une structure courbée et/ou inclinée et/ou étagée. En l’espèce, la première extrémité 81 présente ainsi verticalement une position inférieure à celle de la deuxième extrémité 82. The tie rod 8 also preferably has the shape of a profile. In particular, the tie rod 8 has, along the vertical direction Z, a curved and/or inclined and/or stepped structure. In this case, the first end 81 thus has a position vertically lower than that of the second end 82.
De manière préférentielle encore, le tirant 8 présente une hauteur limitée de sorte à ne pas affecter la garde au sol du véhicule 2. On entend ici par « hauteur » une dimension mesurée le long de la direction verticale entre la position de la première extrémité 81 et une projection de la projection de la deuxième extrémité 82. Still more preferably, the tie rod 8 has a limited height so as not to affect the ground clearance of the vehicle 2. Here, “height” means a dimension measured along the vertical direction between the position of the first end 81 and a projection of the projection of the second end 82.
Les tirants 8 sont disposés de part et d’autre du corps 7 le long de la direction transversale Y de sorte qu’ils définissent un passage au niveau duquel s’étend le corps 7. The tie rods 8 are arranged on either side of the body 7 along the transverse direction Y so that they define a passage at which the body 7 extends.
Particulièrement, le dispositif de support 5 est configuré pour être fixé sur berceau 3 et sur la structure de caisse 4 par l’intermédiaire d’une pluralité de points de fixation compris dans au moins les tirants 8. Chaque tirant 8 comprend ainsi un orifice apte à recevoir un organe de fixation 83 du tirant 8 considéré, et par extension du dispositif de support 5, sur le berceau 3 ou la structure de caisse 4. Par exemple, l’organe de fixation 83 peut être une vis ou un ensemble vis/écrou. De manière préférentielle chaque tirant 8 comprend au moins deux points de fixation distincts. Notamment, dans l’exemple tel qu’exposé précédemment, la première extrémité 81 du tirant 8 est fixée sur le berceau 3 et la structure de caisse 4, superposés l’un à l’autre, tandis que la deuxième extrémité 82 est fixée sur la structure de caisse 4 de sorte à répartir les points de fixation le long du tirant 8. Particularly, the support device 5 is configured to be fixed on the cradle 3 and on the body structure 4 via a plurality of fixing points included in at least the tie rods 8. Each tie rod 8 thus comprises a suitable orifice to receive a fixing member 83 of the tie rod 8 considered, and by extension of the support device 5, on the cradle 3 or the body structure 4. For example, the fixing member 83 can be a screw or a screw/set nut. Preferably each tie rod 8 comprises at least two distinct fixing points. In particular, in the example as explained previously, the first end 81 of the tie rod 8 is fixed on the cradle 3 and the body structure 4, superimposed on one another, while the second end 82 is fixed on the body structure 4 so as to distribute the fixing points along the tie rod 8.
L’agencement 1 selon l’invention, particulièrement le dispositif de support 5, est avantageusement configuré de sorte que le dispositif de support 5 est fixé sur berceau 3 et sur la structure de caisse 4 par-dessous. On entend par « par- dessous » que le dispositif de support 5 s’étend au contact de surface inférieure 301 du berceau 3 et de surface inférieure 401 de la structure de caisse 4, lesdites surfaces inférieures 301 , 401 étant configurées pour être tournées vers le sol au sein du véhicule 2. Autrement dit, lorsque le dispositif de support 5 est monté dans le véhicule 2, au niveau de ses points de fixation il est interposé entre le berceau 3 et la structure de caisse 4 d’une part et le sol sur lequel est disposé l’agencement 1 et/ou le véhicule 2 le long de la direction verticale Z. Ainsi, le dispositif de support 5 présente un positionnement inférieur à des portions du berceau 3 et de la structure de caisse 4 sur lesquelles il est monté. Tel que davantage exposé ci-après en référence au procédé de montage selon l’invention, le dispositif de support 5 peut ainsi être assemblé par le bas sur le berceau 3 et la structure de caisse 4, par intervention d’un technicien sous le véhicule 2. Les points de fixation sont ainsi accessibles depuis sous le véhicule 2, facilitant le montage et le démontage de tout élément ou composant fixé sur le dispositif de support 5. The arrangement 1 according to the invention, particularly the support device 5, is advantageously configured so that the support device 5 is fixed to the cradle 3 and to the body structure 4 below. By “below” is meant that the support device 5 extends in contact with the lower surface 301 of the cradle 3 and the lower surface 401 of the body structure 4, said lower surfaces 301, 401 being configured to be turned towards the ground within the vehicle 2. In other words, when the support device 5 is mounted in the vehicle 2, at its attachment points it is interposed between the cradle 3 and the body structure 4 on the one hand and the ground on which the arrangement 1 and/or the vehicle 2 is arranged along the vertical direction Z. Thus, the support device 5 has a lower positioning than portions of the cradle 3 and the body structure 4 on which it has climbed. As further explained below with reference to the assembly method according to the invention, the support device 5 can thus be assembled from below on the cradle 3 and the body structure 4, by the intervention of a technician under the vehicle 2. The fixing points are thus accessible from under the vehicle 2, facilitating the assembly and disassembly of any element or component fixed on the support device 5.
Tel qu’exposé précédemment, la traverse 9 s’étend le long de la direction transversale Y de sorte à relier les tirants 8 de la paire entre eux. Il en résulte que la traverse 9 relie, indirectement, des parties et/ou éléments de la structure de caisse 4 opposés le long de la direction transversale Y. La traverse 9 et les tirants 8 ont ainsi notamment fonction de renfort du berceau 3, notamment en cas d’impact frontal avec le véhicule 2. Au sein du véhicule 2, la traverse 9 est disposée de sorte à être interposée entre le berceau 3 et le corps 7 du dispositif de support 5 le long de la direction longitudinale X. As explained previously, the crosspiece 9 extends along the transverse direction Y so as to connect the tie rods 8 of the pair together. This results in the crosspiece 9 connecting, indirectly, parts and/or elements of the body structure 4 opposite along the transverse direction Y. The crosspiece 9 and the tie rods 8 thus have the function of reinforcing the cradle 3, in particular in case frontal impact with the vehicle 2. Within the vehicle 2, the crosspiece 9 is arranged so as to be interposed between the cradle 3 and the body 7 of the support device 5 along the longitudinal direction X.
En ce sens, de manière optionnelle mais préférentielle, la traverse 9 et les tirants 8 de la paire de tirants 8 forment un ensemble monobloc. On entend par « monobloc » que la traverse 9 et les tirants 8 ne peuvent être dissociés les uns des autres sans résulter en la dégradation, voire la destruction de ceux-ci. De manière particulière, préférentielle, le corps 7, la traverse 9 et les tirants 8 forment un ensemble monobloc. Un tel dispositif de support 5 permet ainsi avantageusement le renfort de la pièce, la réduction de la chaîne de côte et du nombre de référence et, par voie de conséquence, une simplification de l’assemblage du dispositif de support 5 au sein du véhicule 2. In this sense, optionally but preferably, the crosspiece 9 and the tie rods 8 of the pair of tie rods 8 form a one-piece assembly. By “one-piece” we mean that the crosspiece 9 and the tie rods 8 cannot be separated from each other without resulting in the degradation or even destruction of them. In a particular, preferential manner, the body 7, the crosspiece 9 and the tie rods 8 form a one-piece assembly. Such a support device 5 thus advantageously allows the reinforcement of the part, the reduction of the dimension chain and the reference number and, consequently, a simplification of the assembly of the support device 5 within the vehicle 2 .
Notamment, tout ou partie du dispositif de support 5 peut être réalisé en tôle, aluminium et/ou acier, et peut, par exemple, être embouti, soudé et/ou plié. In particular, all or part of the support device 5 can be made of sheet metal, aluminum and/or steel, and can, for example, be stamped, welded and/or folded.
De manière optionnelle, le dispositif de support 5 peut comprendre, en outre, au moins une ailette 72 de fixation additionnelle du corps 7 sur la structure de caisse 4. En l’espèce, le dispositif de support 5 comprend une paire d’ailettes 72. Notamment, lesdites ailettes 72 s’étendent parallèlement, ou sensiblement parallèlement à la traverse, en direction de l’extérieur du véhicule le long de la direction transversale Y. L’au moins une ailette 72 s’étend également à distance non nulle de la deuxième extrémité 82 du tirant 8 adjacent. Optionally, the support device 5 may further comprise at least one fin 72 for additional fixing of the body 7 on the body structure 4. In this case, the support device 5 comprises a pair of fins 72 In particular, said fins 72 extend parallel, or substantially parallel to the crossmember, towards the exterior of the vehicle along the transverse direction Y. The at least one fin 72 also extends at a non-zero distance. the second end 82 of the adjacent tie rod 8.
Notamment, l’au moins une ailette 72 présente une structure étagée de sorte qu’une extrémité libre de celle-ci s’étend dans un plan distinct d’un plan dans lequel s’inscrit le corps 7. Par exemple, l’extrémité libre de l’au moins une ailette 72 et la deuxième extrémité 81 d’au moins l’un des tirants 8 peuvent s’inscrire dans un même plan. Egalement, dans le cas des véhicules 2 à motorisation hybride ou électrique, c’est-à-dire comprenant au moins une batterie de motricité, il est connu de prévoir, au sein de la structure avant du véhicule 2, un emplacement destiné à un carénage de protection de la batterie. On entend par « carénage » une enveloppe profilée recouvrant ou entourant au moins partiellement la batterie afin d’en assurer la protection. Le dispositif de support 5 peut en outre, de manière optionnelle mais préférentielle, être configuré de sorte à comprendre au moins un point de fixation 10 d’un tel carénage, notamment une pluralité de points de fixation dudit carénage. Dans l’exemple illustré, le dispositif de support 5 comprend quatre points de fixation 10 du carénage de protection. L’agencement 1 selon l’invention peut ainsi avantageusement comprendre un carénage de protection d’une batterie, non représenté, particulièrement d’une batterie de motricité, ou de propulsion, monté directement sur le dispositif de support 5. In particular, the at least one fin 72 has a stepped structure so that a free end thereof extends in a plane distinct from a plane in which the body 7 fits. For example, the end free of at least one fin 72 and the second end 81 of at least one of the tie rods 8 can fit into the same plane. Also, in the case of vehicles 2 with hybrid or electric motorization, that is to say comprising at least one power battery, it is known to provide, within the front structure of the vehicle 2, a location intended for a battery protection shroud. By “fairing” is meant a profiled envelope covering or surrounding at least partially the battery in order to ensure its protection. The support device 5 can furthermore, optionally but preferably, be configured so as to comprise at least one fixing point 10 of such a fairing, in particular a plurality of fixing points of said fairing. In the example illustrated, the support device 5 comprises four attachment points 10 of the protective fairing. The arrangement 1 according to the invention can thus advantageously comprise a protective fairing for a battery, not shown, particularly for a motor or propulsion battery, mounted directly on the support device 5.
Les points de fixation 10 du carénage de protection sont notamment compris dans la traverse 9 et/ou de la paire de tirants 8. En l’espèce, la traverse 9 comprend deux points de fixation 10 du carénage de protection. Particulièrement, lesdites points de fixation 10 sont répartis le long de la traverse 9 de sorte à s’étendre, le long de la direction transversale Y, de part et d’autre du corps 7. Egalement, la paire de tirants 8 peut comprendre et/ou porter une pluralité de points de fixation 10 du carénage de protection. Dans l’exemple illustré, chaque tirant 8 porte une extension latérale 84 comportant l’un des points de fixation 10 du carénage de protection. Les extensions latérales 84 sont notamment portées par la deuxième extrémité 82 de chaque tirant 8 est sont configurées pour s’étendre vers l’extérieur du véhicule 2 lorsque l’agencement 1 est équipé au sein de celui-ci. De manière préférentielle, chaque extension latérale 84 et tirant 8 forment un ensemble monobloc. The fixing points 10 of the protective fairing are in particular included in the crosspiece 9 and/or the pair of tie rods 8. In this case, the crosspiece 9 includes two fixing points 10 of the protective fairing. Particularly, said fixing points 10 are distributed along the crosspiece 9 so as to extend, along the transverse direction Y, on either side of the body 7. Also, the pair of tie rods 8 can comprise and /or carry a plurality of attachment points 10 of the protective fairing. In the example illustrated, each tie rod 8 carries a lateral extension 84 comprising one of the attachment points 10 of the protective fairing. The lateral extensions 84 are notably carried by the second end 82 of each tie rod 8 and are configured to extend towards the outside of the vehicle 2 when the arrangement 1 is equipped within it. Preferably, each lateral extension 84 and tie rod 8 form a one-piece assembly.
De manière optionnelle mais préférentielle, le dispositif de support 5 peut avantageusement comprendre au moins une zone de fixation d’au moins un tuyau 11 de circulation d’un fluide. Par exemple, un tel tuyau 11 de circulation peut être configuré pour permettre la circulation d’un liquide tel que de l’eau ou un fluide de refroidissement. Notamment, un tel tuyau 11 de circulation peut être destiné à alimenter une installation de chauffage, ventilation et climatisation, ou HVAC de l’anglais « heating, ventilation and air-conditioning », ou un système de traitement thermique d’au moins un élément de la chaîne de traction électrique. L’agencement 1 selon l’invention peut également comprendre au moins un tuyau 11 de circulation d’un fluide. Dans l’exemple illustré, une pluralité de tuyaux 11 de circulation d’un fluide sont raccordés au dispositif de support 5 et/ou au composant 6, ici le boîtier de chauffage. Optionally but preferably, the support device 5 can advantageously comprise at least one zone for fixing at least one pipe 11 for circulating a fluid. For example, such a circulation pipe 11 can be configured to allow the circulation of a liquid such as water or a cooling fluid. In particular, such a circulation pipe 11 may be intended to supply a heating, ventilation and air conditioning, or HVAC, installation, or a heat treatment system of at least one element. of the electric traction chain. The arrangement 1 according to the invention can also include at least one pipe 11 for circulating a fluid. In the example illustrated, a plurality of pipes 11 for circulating a fluid are connected to the support device 5 and/or to the component 6, here the heating box.
Par exemple, tel qu’illustré pour un premier tuyau 11 a et un deuxième tuyau 11 b de circulation, une périphérie extérieure du tuyau 11 de circulation considéré peut comprendre un doigt ou un pion configuré pour être inséré dans un orifice 73 compris dans le dispositif de support 5. Alternativement ou additionnellement, la fixation du tuyau 11 de circulation considéré sur le dispositif de support 5 peut être réalisée par l’intermédiaire d’un élément de fixation 12, par exemple, tel qu’illustré, comprenant une bague configurée pour entourer au moins partiellement ledit tuyau 11 et une base apte à coopérer avec le dispositif de support 5, par exemple avec un orifice 73 tel qu’exposé plus haut. De manière optionnelle, ladite base peut comprendre un mécanisme de fixation tel qu’un clip. For example, as illustrated for a first circulation pipe 11 a and a second circulation pipe 11 b, an outer periphery of the circulation pipe 11 considered may comprise a finger or a pin configured to be inserted into an orifice 73 included in the device support 5. Alternatively or additionally, the fixing of the circulation pipe 11 considered on the support device 5 can be carried out via a fixing element 12, for example, as illustrated, comprising a ring configured to at least partially surround said pipe 11 and a base capable of cooperating with the support device 5, for example with an orifice 73 as explained above. Optionally, said base may include a fixing mechanism such as a clip.
Dans l’exemple illustré, la fixation de l’au moins un tuyau 11 peut être réalisée au niveau d’au moins l’une des ailettes 72. Notamment, les ailettes 72 du dispositif de support 5 comprennent au moins un orifice 73 apte à recevoir un doigt, pion et/ou un élément de fixation 12 tel qu’exposé précédemment. Additionnellement ou alternativement, la fixation de l’au moins un tuyau 11 peut être réalisée par liaison directe ou indirecte au corps 7 du dispositif de support 5. Par exemple, tel qu’illustré, le corps 7 peut porter une languette 74 comprenant au moins un orifice 73 apte à recevoir un doigt, pion et/ou un élément de fixation 12 tel qu’exposé précédemment. De manière préférentielle, une telle languette 74 est issue du côté latéral du corps 7. Egalement, une telle languette 74 peut être disposée entre au moins l’une des ailettes 72 et la traverse 9 le long de la direction longitudinale X. Selon un exemple non représenté, mis en œuvre alternativement ou additionnellement aux exemples précédents, l’au moins un tuyau 11 peut être fixé sur le dispositif de support 5 au niveau de la traverse 9. In the example illustrated, the fixing of the at least one pipe 11 can be carried out at at least one of the fins 72. In particular, the fins 72 of the support device 5 comprise at least one orifice 73 capable of receive a finger, pin and/or a fixing element 12 as explained previously. Additionally or alternatively, the fixing of the at least one pipe 11 can be carried out by direct or indirect connection to the body 7 of the support device 5. For example, as illustrated, the body 7 can carry a tongue 74 comprising at least an orifice 73 capable of receiving a finger, pin and/or a fixing element 12 as explained previously. Preferably, such a tongue 74 comes from the lateral side of the body 7. Also, such a tongue 74 can be arranged between at least one of the fins 72 and the crosspiece 9 along the longitudinal direction X. According to an example not shown, implemented alternatively or additionally to the previous examples, the at least one pipe 11 can be fixed on the support device 5 at the level of the crosspiece 9.
De manière optionnelle mais préférentielle, le dispositif de support 5 selon l’invention peut avantageusement comprendre au moins une zone de fixation d’un câble d’alimentation 13 électrique. Par exemple, le câble d’alimentation 13 considéré peut être un câble d’alimentation 13 bas voltage, par exemple 12V, pour l’alimentation de la batterie de servitude, et/ou peut être un câble d’alimentation 13 haut voltage, par exemple 400V, notamment de la batterie de motricité. L’agencement 1 peut ainsi également comprendre au moins un câble d’alimentation 13 électrique. Dans l’exemple illustré, une pluralité de câbles d’alimentation 13 électrique sont fixés sur le dispositif de support 5, un premier câble 13a étant un câble d’alimentation 12V et un deuxième câble 13b étant un câble d’alimentation 400V. Optionally but preferably, the support device 5 according to the invention can advantageously comprise at least one zone for fixing an electrical power cable 13. For example, the power cable 13 considered may be a low voltage power cable 13, for example 12V, for powering the utility battery, and/or may be a high voltage power cable 13, for example example 400V, in particular of the motor battery. Arrangement 1 can thus also include at least one electrical power cable 13. In the example illustrated, a plurality of electrical power cables 13 are fixed on the support device 5, a first cable 13a being a 12V power cable and a second cable 13b being a 400V power cable.
Similairement à ce qui a été exposé précédemment en référence au tuyau 11 de circulation d’un fluide, une périphérie extérieure d’au moins l’un desdits câbles 13 peut être configurée pour coopérer avec un trou 75 compris dans le dispositif de support 5. Alternativement ou additionnellement, la fixation du câble considéré peut être réalisée par l’intermédiaire d’un élément de maintien 14, similaire à l’élément de fixation 12 tel que décrit précédemment. Par exemple, l’élément de maintien 14 peut comprendre une bague configurée pour entourer au moins partiellement le câble et une base apte à coopérer avec le dispositif de support 5, notamment au moyen d’un clip. Similar to what was explained previously with reference to the pipe 11 for circulating a fluid, an outer periphery of at least one of said cables 13 can be configured to cooperate with a hole 75 included in the support device 5. Alternatively or additionally, the fixing of the cable in question can be carried out via a holding element 14, similar to the fixing element 12 as described previously. For example, the holding element 14 may comprise a ring configured to at least partially surround the cable and a base capable of cooperating with the support device 5, in particular by means of a clip.
Dans l’exemple illustré, la fixation du premier câble 13a est réalisée au niveau de la traverse 9. Alternativement ou additionnellement, la fixation d’un tel câble peut être réalisée au niveau d’au moins l’une des ailettes 72. Additionnellement ou alternativement, tel que représenté pour le deuxième câble 13b, la fixation de l’au moins un câble peut être réalisée par liaison directe ou indirecte au corps 7 du dispositif de support 5. Par exemple, tel qu’illustré, le corps 7 peut porter une patte 76 configurée pour permettre la fixation et le maintien d’au moins l’un des câbles, par exemple par l’intermédiaire d’une vis ou d’une agrafe. La patte 76 s’étend notamment transversalement, particulièrement orthogonalement au corps 7. Elle s’étend notamment au moins en partie verticalement, vers le haut. La patte 76 est, de manière préférentielle, issue du côté distal du corps 7 de sorte à être la plus distante de tout contact en cas de choc frontal. Egalement, la patte 76 peut s’étendre au contact du composant 6 et/ou être configurée pour former butée dudit composant 6 le long d’au moins une direction, notamment le long de la direction longitudinale X, par exemple en cas de choc frontal. De tels exemples de fixation permettent avantageusement de limiter les déplacements des câbles électriques au sein de la structure avant, limitant ainsi les risques de corrosion par frettage, ou « fretting corrosion » en anglais. In the example illustrated, the fixing of the first cable 13a is carried out at the level of the crosspiece 9. Alternatively or additionally, the fixing of such a cable can be carried out at the level of at least one of the fins 72. Additionally or alternatively, as shown for the second cable 13b, the fixing of the at least one cable can be carried out by direct or indirect connection to the body 7 of the support device 5. For example, as illustrated, the body 7 can carry a tab 76 configured to allow the fixing and maintaining of at least one of the cables, for example via a screw or a clip. The tab 76 extends in particular transversely, particularly orthogonally to the body 7. It extends in particular at least partly vertically, upwards. The tab 76 is, preferably, coming from the distal side of the body 7 so as to be the furthest from any contact in the event of a frontal impact. Also, the tab 76 can extend into contact with the component 6 and/or be configured to form a stop for said component 6 along at least one direction, in particular along the longitudinal direction X, for example in the event of a frontal impact. . Such examples of fixing advantageously make it possible to limit the movement of the electrical cables within the front structure, thus limiting the risks of corrosion by fretting, or “fretting corrosion” in English.
De manière optionnelle mais préférentielle, l’agencement 1 peut comprendre des éléments de liaison 15 configurés pour maintenir entre eux différents tuyaux de circulation 11 et/ou différents câbles d’alimentation 13 électrique. Optionally but preferentially, the arrangement 1 may include connecting elements 15 configured to hold together different circulation pipes 11 and/or different electrical power cables 13.
Outre le renfort du berceau 3 et le support d’un composant 6 de la structure avant du véhicule 2, ici du boîtier de chauffage, le dispositif de support 5 peut ainsi optionnellement permettre, sur la base des différentes options exposées précédemment : In addition to the reinforcement of the cradle 3 and the support of a component 6 of the front structure of the vehicle 2, here of the heating box, the support device 5 can thus optionally allow, on the basis of the different options explained previously:
- la fixation du carénage de protection de batterie ; et/ou - fixing the battery protection fairing; and or
- la fixation d’au moins un tuyau 11 de circulation d’un fluide ; et/ou - fixing at least one pipe 11 for circulating a fluid; and or
- la fixation d’au moins un câble d’alimentation 13 électrique. - fixing at least one electrical power cable 13.

The support device 5 and the arrangement 1 according to the invention thus advantageously allow simultaneous and simplified access to different devices and systems fitted to the front structure of the vehicle 2, in this case selected from the heating box, a hydraulic system, an electrical system and the protective fairing.
Le dispositif de support 5 permet en outre un montage simplifié du dispositif de support 5 et des dispositifs et systèmes précités au sein du véhicule 2, d’une part en réduisant la chaîne de côte et les dispersions, tel qu’exposé plus haut, et d’autre part en permettant un montage et une fixation du dispositif de support 5 par-dessous dans le véhicule 2. The support device 5 also allows simplified assembly of the support device 5 and the aforementioned devices and systems within the vehicle 2, on the one hand by reducing the coastline and dispersions, as explained above, and on the other hand by allowing mounting and fixing of the support device 5 from below in the vehicle 2.
En ce sens, l’invention concerne également un procédé de montage de l’agencement 1 selon l’invention au sein d’un véhicule 2.

In this sense, the invention also relates to a method of mounting the arrangement 1 according to the invention within a vehicle 2. Such a method comprises, in general, fixing the support device 5 from below on the cradle 3 and on the body structure 4 via a plurality of fixing points. The attachment points are particularly included in at least the tie rods 8 and the support device 5 is arranged so as to extend in contact with the lower surfaces 301, 401 of the cradle 3 and the body structure 4. The support device 5, particularly at least the pair of tie rods 8, is thus at least partially interposed between the cradle 3 and the body structure 4 on which it is fixed on the one hand and the ground on the other hand along the vertical direction Z .
Notamment, la première extrémité 81 des tirants 8 peut être fixée sur le berceau 3 et la structure de caisse 4 au niveau d’une zone du berceau 3 verticalement superposée sur la structure de caisse 4. La deuxième extrémité 82 est, quant à elle, fixée sur la structure de caisse 4. In particular, the first end 81 of the tie rods 8 can be fixed on the cradle 3 and the body structure 4 at the level of an area of the cradle 3 vertically superimposed on the body structure 4. The second end 82 is, for its part, fixed to the body structure 4.
