Description

STRUCTURE POUR FACE AVANT DE VEHICULE AUTOMOBILE  STRUCTURE FOR FRONT PANEL OF MOTOR VEHICLE
L'invention a pour objet une structure pour face avant de véhicule automobile. The subject of the invention is a structure for the front face of a motor vehicle.
Une structure pour face avant de véhicule automobile comprend généralement une traverse supérieure solidaire d'une traverse inférieure par l'intermédiaire de deux jambes disposées verticalement dans le véhicule automobile. A structure for a motor vehicle front face generally comprises an upper cross member secured to a lower cross member via two legs arranged vertically in the motor vehicle.
De manière connue, une telle structure pour face avant s'étend dans le véhicule automobile d'un bouclier jusqu'à un tablier du véhicule et permet de solidariser un compartiment moteur ou de supporter un groupe motoventilateur. Une telle structure est notamment visible par un usager lorsque le capot avant du véhicule se trouve à l'état ouvert. In a known manner, such a structure for the front face extends in the motor vehicle from a shield to a deck of the vehicle and makes it possible to secure an engine compartment or to support a motor-fan unit. Such a structure is particularly visible by a user when the front cover of the vehicle is in the open state.
Traditionnellement, la structure pour face avant est constituée en acier, qui assure en particulier une résistance et une raideur élevées. Traditionally, the structure for front face is made of steel, which ensures in particular a high resistance and stiffness.
Toutefois, afin d'alléger le véhicule automobile, on a recourt à une structure en matériau composite. However, in order to lighten the motor vehicle, it is resorted to a composite material structure.
Néanmoins, le matériau composite présente l'inconvénient d'être difficile à mettre en forme tout en conservant un bon aspect extérieur de la structure. Il en résulte des défauts d'aspect esthétique sur certaines zones de la structure, qui sont visibles par un utilisateur lorsque le capot de la voiture est ouvert. Nevertheless, the composite material has the disadvantage of being difficult to shape while maintaining a good external appearance of the structure. This results in aesthetic defects in certain areas of the structure, which are visible by a user when the hood of the car is open.
Par ailleurs, le matériau composite de certaines zones de la structure est susceptible d'être endommagé par usure ou par rayure par exemple, du fait qu'il est facilement accessible par un utilisateur. Furthermore, the composite material of certain areas of the structure is susceptible to being damaged by wear or scratching, for example, because it is easily accessible by a user.
Le but de l'invention est de remédier au moins partiellement à ces inconvénients. The object of the invention is to at least partially overcome these disadvantages.
A cet effet, l'invention a pour objet une structure pour face avant de véhicule automobile, comprenant au moins une première portion constituée dans un matériau composite et une deuxième portion recouvrant partiellement la première portion, la deuxième portion présentant une surface extérieure constituée dans un matériau différent du matériau composite de la première portion. For this purpose, the subject of the invention is a structure for a front face of a motor vehicle, comprising at least a first portion constituted by in a composite material and a second portion partially covering the first portion, the second portion having an outer surface formed of a material different from the composite material of the first portion.
La surface extérieure de la deuxième portion permet ainsi de masquer certaines zones déterminées de la première portion tout en laissant visible le matériau composite de la structure dans certaines autres zones. The outer surface of the second portion thus makes it possible to mask certain determined zones of the first portion while leaving visible the composite material of the structure in certain other zones.
Selon une autre caractéristique de l'invention, les deux portions sont directement solidaires l'une de l'autre. According to another characteristic of the invention, the two portions are directly integral with each other.
Selon une autre caractéristique de l'invention, la deuxième portion est entièrement constituée dans un matériau différent du matériau composite de la première portion. According to another characteristic of the invention, the second portion is entirely made of a material different from the composite material of the first portion.
Selon une autre caractéristique de l'invention, la deuxième portion comprend une partie constituée dans un matériau composite, la partie en matériau composite étant recouverte par une couche en un matériau différent du matériau composite de la première portion. According to another characteristic of the invention, the second portion comprises a portion made of a composite material, the part of composite material being covered by a layer of a material different from the composite material of the first portion.
Selon une autre caractéristique de l'invention, le matériau différent du matériau composite de la deuxième portion est un matériau plastique. According to another characteristic of the invention, the material different from the composite material of the second portion is a plastic material.
Selon une autre caractéristique de l'invention, la structure comprend deux portions recouvrant partiellement la première portion, les deux portions présentant une surface extérieure constituée dans un matériau différent du matériau composite de la première portion. According to another characteristic of the invention, the structure comprises two portions partially covering the first portion, the two portions having an outer surface made of a material different from the composite material of the first portion.
Selon une autre caractéristique de l'invention, la structure est destinée à être disposée horizontalement dans le véhicule automobile. According to another characteristic of the invention, the structure is intended to be arranged horizontally in the motor vehicle.
L'invention concerne également un procédé de fabrication d'une structure pour face avant de véhicule automobile, comprenant une étape d'assemblage par compression d'au moins une première portion constituée dans un matériau composite et d'une deuxième portion présentant une surface extérieure constituée dans un matériau différent du matériau composite de la première portion. The invention also relates to a method for manufacturing a structure for a front face of a motor vehicle, comprising a step of assembling by compression of at least a first portion made of a composite material and a second portion having an outer surface. made of a material different from the material composite of the first portion.
Selon une autre caractéristique de l'invention, le procédé comprend une étape de positionnement de la première portion et de la deuxième portion, de sorte à ce que la première portion et la deuxième portion se recouvrent partiellement, l'étape de positionnement étant préalable à l'étape d'assemblage. According to another characteristic of the invention, the method comprises a step of positioning the first portion and the second portion, so that the first portion and the second portion overlap partially, the positioning step being prior to the assembly step.
Selon une autre caractéristique de l'invention, le procédé comprend une étape de chauffage. According to another characteristic of the invention, the method comprises a heating step.

Bien entendu, l'invention ne se limite pas à des portions 3, 4 identiques, mais plusieurs formes sont possibles, selon la forme ou l'aspect souhaité de la structure 1 . Of course, the invention is not limited to identical portions 3, 4, but several shapes are possible, depending on the desired shape or appearance of the structure 1.
Comme visible sur la figure 1 , la traverse 1 présente une forme générale de U. As visible in Figure 1, the cross member 1 has a general shape of U.
La deuxième portion 3 et la troisième portion 4 sont situées au niveau de deux branches d'extrémité de la traverse 1 , tandis que la première portion 2 est visible au niveau d'une branche centrale de la traverse 1 . The second portion 3 and the third portion 4 are located at two end branches of the cross member 1, while the first portion 2 is visible at a central branch of the cross member 1.
Comme visible sur la figure 1 , la branche centrale de la traverse 1 présente une surface extérieure constituée dans le matériau composite de la première portion 2. As can be seen in FIG. 1, the central branch of the cross member 1 has an outer surface formed in the composite material of the first portion 2.
La première portion 2 et la deuxième portion 3 sont directement solidaires. The first portion 2 and the second portion 3 are directly integral.
De même, la première portion 2 et la troisième portion 4 sont directement solidaires. Similarly, the first portion 2 and the third portion 4 are directly integral.
La deuxième portion 3 et la troisième portion 4 sont solidarisées l'une à l'autre par l'intermédiaire de la première portion 2. Premier mode de réalisation The second portion 3 and the third portion 4 are secured one to the other via the first portion 2. First embodiment

Selon ce mode de réalisation, la première portion 2 présente une forme de U similaire à la forme générale de la traverse 1 . According to this embodiment, the first portion 2 has a U-shape similar to the general shape of the crossbar 1.
Les deuxième et troisième portions 3, 4 présentent respectivement une forme similaire à chacune des branches d'extrémité de la première portion 2. The second and third portions 3, 4 respectively have a shape similar to each of the end branches of the first portion 2.
Comme visible sur la figure 2B, l'ensemble de la deuxième portion 3 recouvre une branche d'extrémité de la première portion 2. As can be seen in FIG. 2B, the whole of the second portion 3 covers an end branch of the first portion 2.
De même, l'ensemble de la troisième portion 4 recouvre l'autre branche d'extrémité de la première portion 2. Similarly, the whole of the third portion 4 covers the other end branch of the first portion 2.
Il est ainsi possible de définir deux types de surface, la première portion 2 correspond à une surface dite visible, la première portion 2 étant visible ou à découvert, tandis que les deuxième et troisième portions 3, 4 correspond à une surface dite couverte, la première portion 2 étant couverte. It is thus possible to define two types of surface, the first portion 2 corresponds to a so-called visible surface, the first portion 2 being visible or uncovered, while the second and third portions 3, 4 corresponds to a so-called covered surface, the first portion 2 being covered.
Il est ainsi possible de définir un rapport entre la surface visible, en d'autres termes la surface visible de la portion 2, et la surface couverte, ou encore la surface visible des portions 3 et 4. Il est ainsi possible en fonction des besoins mécaniques tels que la rigidité ou le poids, d'adapter au mieux ce rapport pour obtenir la traverse 1 désirée. Le rapport entre la surface visible de la portion 2 et la surface couverte, autrement dit la surface visible des portions 3 et 4, varie entre 0,1 et 0,9. On peut aussi dire que le rapport entre la surface de la portion 2 à découvert et la surface de la portion 2 recouverte, à savoir la surface des portions 3 et 4, à varie de 10 % à 90 % It is thus possible to define a ratio between the visible surface, in other words the visible surface of the portion 2, and the covered surface, or the visible surface of the portions 3 and 4. It is thus possible according to mechanical needs such as rigidity or weight, to better adapt this ratio to obtain the desired cross 1. The ratio between the visible surface of the portion 2 and the covered surface, in other words the visible surface of the portions 3 and 4, varies between 0.1 and 0.9. It can also be said that the ratio between the area of the exposed portion 2 and the surface of the covered portion 2, namely the area of the portions 3 and 4, varies from 10% to 90%

De préférence, les parties 5, 7 en matériau composite de la deuxième portion 3 et de la troisième portion 4 sont de composition identique au matériau composite constituant la première portion 2. Les couches 6, 8 sont de préférence en un matériau plastique. Preferably, the parts 5, 7 of composite material of the second portion 3 and the third portion 4 are of identical composition to the composite material constituting the first portion 2. The layers 6, 8 are preferably made of a plastic material.
La troisième portion 3 et la troisième portion 4 forment deux branches d'extrémité de la traverse 1 , tandis que la première portion 2 forme une branche centrale de la traverse 1 . The third portion 3 and the third portion 4 form two end branches of the cross member 1, while the first portion 2 forms a central branch of the cross member 1.
Comme visible sur la figure 3, la première portion 2 comprend deux extrémités, référencées 9 et 10, la deuxième portion 3 comprend deux extrémités, référencées 1 1 et 12, et la troisième portion 4 comprend deux extrémités, référencées 13 et 14.

Comme visible sur les figures 3B, la première portion 2 et la deuxième portion 3 se recouvrent partiellement, l'extrémité 1 1 de la deuxième portion 3 étant solidaire par recouvrement de l'extrémité 9 de la première portion 2. As can be seen in FIGS. 3B, the first portion 2 and the second portion 3 partially overlap, the end 1 1 of the second portion 3 being secured by covering the end 9 of the first portion 2.
L'autre extrémité 12 de la deuxième portion 3 est libre. The other end 12 of the second portion 3 is free.

Procédé de fabrication Manufacturing process
L'invention a également pour objet un procédé de fabrication de la structure 1 pour face avant de véhicule automobile. The invention also relates to a method of manufacturing the structure 1 for the front face of a motor vehicle.
Le procédé de fabrication est décrit dans son application à la traverse 1 illustrée à la figure 1 selon le premier et le deuxième mode de réalisation. The manufacturing method is described in its application to the cross member 1 illustrated in Figure 1 according to the first and the second embodiment.
Bien entendu, l'invention ne se limite pas à une traverse à trois portions, mais le procédé permet d'obtenir toute structure 1 pour face avant de véhicule automobile comprenant au moins deux portions. Of course, the invention is not limited to a cross with three portions, but the method allows to obtain any structure 1 for the front of a motor vehicle comprising at least two portions.
Le procédé comprend une étape de positionnement de chaque portion 2, 3, 4. The method comprises a step of positioning each portion 2, 3, 4.
Pour réaliser la traverse 1 selon le premier mode de réalisation illustré par la figure 2A au cours de l'étape de positionnement, la première portion 2 et la deuxième portion 3 sont disposées de sorte que l'ensemble de la deuxième portion 3 recouvre une branche d'extrémité de la première portion 2. To produce the cross member 1 according to the first embodiment illustrated in FIG. 2A during the positioning step, the first portion 2 and the second portion 3 are arranged so that the whole of the second portion 3 covers a branch end of the first portion 2.
De même, au cours de l'étape de positionnement, la première portion 2 et la troisième portion 4 sont disposées de sorte que l'ensemble de la troisième portion 4 recouvre l'autre branche d'extrémité de la première portion 2. Similarly, during the positioning step, the first portion 2 and the third portion 4 are arranged so that the whole of the third portion 4 covers the other end branch of the first portion 2.
Selon le premier mode de réalisation, la première portion 2 a une épaisseur comprise entre 1 millimètre et 3 millimètres. La deuxième portion 3 et la troisième portion 4 ont respectivement une épaisseur comprise entre 0,2 millimètre et 0,5 millimètre. According to the first embodiment, the first portion 2 has a thickness of between 1 millimeter and 3 millimeters. The second portion 3 and the third portion 4 respectively have a thickness of between 0.2 millimeter and 0.5 millimeter.
Pour réaliser la traverse selon le deuxième mode de réalisation illustré par la figure 3A au cours de l'étape de positionnement, la deuxième portion 3 et la première portion 2 sont disposées de sorte à se recouvrir partiellement, l'extrémité 1 1 de la deuxième portion 3 étant superposée avec l'extrémité 9 de la première portion 2. To produce the cross member according to the second embodiment illustrated in FIG. 3A during the positioning step, the second portion 3 and the first portion 2 are arranged so as to overlap partially, the end 1 1 of the second portion 3 being superimposed with the end 9 of the first portion 2.
De même, au cours de l'étape de positionnement, la troisième portion 4 et la première portion 2 se recouvrent partiellement, l'extrémité 13 de la troisième portion 4 étant superposée avec l'extrémité 10 de la première portion 2. Similarly, during the positioning step, the third portion 4 and the first portion 2 overlap partially, the end 13 of the third portion 4 being superimposed with the end 10 of the first portion 2.
Selon le deuxième mode de réalisation, la première portion 2 a une épaisseur comprise entre 1 millimètre et 3 millimètres. Les parties composites 5,7 de la deuxième portion 3 et la troisième portion 4 ont une épaisseur respectivement comprise entre 1 millimètre et 2 millimètres. Les couches 6,8 de la deuxième portion 3 et de la troisième portion 4 ont une épaisseur respectivement comprise entre 0,2 millimètre et 0,5 millimètre. According to the second embodiment, the first portion 2 has a thickness of between 1 millimeter and 3 millimeters. The composite parts 5, 7 of the second portion 3 and the third portion 4 have a thickness respectively of between 1 millimeter and 2 millimeters. The layers 6,8 of the second portion 3 and the third portion 4 have a thickness respectively of between 0.2 millimeter and 0.5 millimeter.
L'étape de positionnement est préalable à l'étape d'assemblage. The positioning step is prior to the assembly step.
Avantageusement, une fois positionnées les unes relativement aux autres, les portions 2, 3, 4 sont maintenus dans un cadre de maintien, non illustré. Advantageously, once positioned relative to each other, the portions 2, 3, 4 are held in a holding frame, not shown.
De préférence, le procédé comprend une étape de chauffage, les portions 2, 3, 4 étant chauffées une fois positionnées ensemble dans le cadre de maintien. Preferably, the method comprises a heating step, the portions 2, 3, 4 being heated once positioned together in the holding frame.
Le procédé comprend ensuite une étape d'assemblage de la première portion 2, de la deuxième portion 3 et de la troisième portion 4. The method then comprises a step of assembling the first portion 2, the second portion 3 and the third portion 4.
On place les portions 2, 3, 4 une fois positionnées, éventuellement chauffées, dans un outil de formage. Au cours de l'étape d'assemblage, on presse les portions 2, 3, 4 entre elles de sorte que les portions 2, 3, 4 se solidarisent par consolidation. The portions 2, 3, 4 are placed once positioned, possibly heated, in a forming tool. During the assembly step, the portions 2, 3, 4 are pressed together so that the portions 2, 3, 4 solidify by consolidation.
Ainsi, la structure 1 est fabriquée par une seule étape d'assemblage. Thus, the structure 1 is manufactured by a single assembly step.
La structure une fois assemblée a une épaisseur totale comprise entre 1 ,5 millimètres et 4,5 millimètres, notamment entre 1 ,5 millimètres et 3,5 millimètres. Once assembled, the structure has a total thickness of between 1.5 millimeters and 4.5 millimeters, in particular between 1.5 millimeters and 3.5 millimeters.
Suite à l'étape d'assemblage, le procédé peut avantageusement comprendre une étape de surmoulage tout en laissant visible au moins partiellement la surface extérieure de la structure 1 . Lors de l'étape de surmoulage, on injecte une matrice, par exemple en résine thermoplastique dans un moule d'injection dans laquelle a été placée la structure 1 assemblée. Following the assembly step, the method may advantageously include an overmolding step while leaving at least partially visible the outer surface of the structure 1. During the overmolding step, a matrix, for example a thermoplastic resin, is injected into an injection mold in which the assembled structure 1 has been placed.
L'étape de surmoulage permet notamment de créer des formes qui servent d'interfaces de fixation (fixations véhicule, radiateurs, réservoir de liquide de refroidissement, phares, etc..) ou qui servent à renforcer la structure (nervures). The overmolding step allows in particular to create shapes that serve as fixing interfaces (vehicle fasteners, radiators, coolant tank, headlights, etc. ..) or that serve to strengthen the structure (ribs).
Troisième mode de réalisation Third embodiment
Dans un troisième mode de réalisation illustré par les figures 4 et 4A, la deuxième portion 3 est entièrement constituée dans un matériau différent du matériau composite de la première portion 2. Comme pour le premier mode de réalisation, la deuxième portion 3 et la troisième portion 4 sont avantageusement des couches en un matériau plastique. In a third embodiment illustrated by FIGS. 4 and 4A, the second portion 3 consists entirely of a material different from the composite material of the first portion 2. As for the first embodiment, the second portion 3 and the third portion 4 are advantageously layers of a plastic material.
Pour réaliser la traverse 1 selon le troisième mode de réalisation illustré par les figures 4 et 4A, on dispose initialement d'un premier élément 15 recouvert partiellement par un deuxième élément 16 et un troisième élément 17. Selon le troisième mode de réalisation illustré, le premier élément 15 est constitué dans matériau composite. Les deuxième et troisième éléments 16, 17 sont constitués dans un matériau différent du matériau composite du premier élément 15, notamment dans un matériau plastique. To produce the cross member 1 according to the third embodiment illustrated by FIGS. 4 and 4A, there is initially a first element 15 partly covered by a second element 16 and a third element 17. According to the third embodiment illustrated, the first element 15 is made of composite material. The second and third elements 16, 17 are made of a material different from the composite material of the first element 15, especially in a material plastic.
Comme visible sur la figure 4, les deuxième et troisième éléments 16, 17 forment des bandes, en particulier parallèles entre elles, recouvrant de chaque côté le premier élément 15, tandis que le premier élément 15 reste visible au niveau d'une bande centrale. As visible in Figure 4, the second and third elements 16, 17 form strips, in particular parallel to each other, covering on each side the first element 15, while the first element 15 remains visible at a central band.
Les éléments 15, 16, 17 sont préalablement assemblés et solidarisés entre eux. Les éléments 15, 16, 17 peuvent par exemple être assemblés selon l'étape d'assemblage du procédé de fabrication précédemment décrit précédemment pour les premier et deuxième modes de réalisation. Cependant, les éléments 15, 16, 17 peuvent également être assemblées par tout autre procédé permettant d'obtenir une solidarisation entre eux, par exemple lors d'une étape de laminage. The elements 15, 16, 17 are previously assembled and joined together. The elements 15, 16, 17 may for example be assembled according to the assembly step of the manufacturing method previously described above for the first and second embodiments. However, the elements 15, 16, 17 can also be assembled by any other method that makes it possible to join together, for example during a rolling step.
Le procédé de fabrication selon le troisième mode de réalisation comprend une étape de découpage des éléments 15, 16, 17. The manufacturing method according to the third embodiment comprises a step of cutting the elements 15, 16, 17.
Au cours de l'étape de découpage on découpe directement la structure 1 dans les éléments 15, 16, 17 (selon les pointillés représentés sur la figure 4). During the cutting step, the structure 1 is cut directly into the elements 15, 16, 17 (according to the dots shown in FIG. 4).
Une fois découpé, on obtient directement la structure 1 selon l'invention. Once cut, we directly obtain the structure 1 according to the invention.
Il n'est donc pas nécessaire selon ce troisième mode de réalisation, de réaliser une étape de positionnement ou une étape d'assemblage. It is therefore not necessary according to this third embodiment, to perform a positioning step or an assembly step.
Avantages Advantages
Comme déjà indiqué, la configuration avec des deuxième et troisième portions 3, 4 permet de masquer certaines zones en matériau composite de la structure 1 , tandis que d'autres zones montrant le matériau composite restent visibles. As already indicated, the configuration with second and third portions 3, 4 makes it possible to mask certain composite material zones of the structure 1, whereas other zones showing the composite material remain visible.
Comme visible sur la figure 1 , le matériau composite peut par exemple être visible sur la branche centrale de la structure 1 tandis que les branches d'extrémités peuvent présenter un aspect de surface différent. La configuration permet également d'améliorer l'esthétique de la structure 1 en modifiant l'aspect de certaines portions de la structure 1 , par exemple par ajout de de couleur, de forme ou de relief. As can be seen in FIG. 1, the composite material may for example be visible on the central branch of the structure 1 while the end branches may have a different surface appearance. The configuration also makes it possible to improve the aesthetics of the structure 1 by modifying the appearance of certain portions of the structure 1, for example by adding color, shape or relief.
Selon une réalisation, la surface extérieure de la deuxième portion 3 et/ou de la troisième portion 4 présentent un aspect granuleux ou grenu. Selon cette réalisation, le procédé de fabrication de la structure 1 selon le premier ou le deuxième mode de réalisation peut comprendre une étape de grainage de la surface extérieure des deuxième et troisième portions 3, 4. In one embodiment, the outer surface of the second portion 3 and / or the third portion 4 have a granular or grainy appearance. According to this embodiment, the manufacturing method of the structure 1 according to the first or second embodiment may comprise a graining step of the outer surface of the second and third portions 3, 4.
Selon une autre réalisation, la surface extérieure de la deuxième portion 3 et/ou de la troisième portion 4 présentent un aspect mat ou un aspect brillant. In another embodiment, the outer surface of the second portion 3 and / or the third portion 4 have a matte appearance or a glossy appearance.
