Domaine technique auquel se rapporte l'inventionTechnical field to which the invention relates
[0001] La présente invention revendique la priorité de la demande française 2110536 déposée le 5 octobre 2021 , dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application 2110536 filed on October 5, 2021, the content of which (text, drawings and claims) is incorporated herein by reference.
[0002] La présente invention concerne un capot pour véhicule automobile comprenant un renfort de doublure. The present invention relates to a bonnet for a motor vehicle comprising a lining reinforcement.
Arrière-plan technologique Technology background
[0003] De façon connue, un capot pour véhicule automobile se compose d'un panneau externe superposé à un panneau interne, le panneau interne étant destiné à être en vis-à-vis du compartiment moteur du véhicule automobile. In known manner, a bonnet for a motor vehicle consists of an outer panel superimposed on an inner panel, the inner panel being intended to be vis-à-vis the engine compartment of the motor vehicle.
[0004] Afin de donner une certaine tenue géométrique au capot ainsi qu’un peu de raideur statique et de l'inertie, une doublure est collée et/ou sertie au niveau de la périphérie du panneau externe. Des plots de calage, généralement en mastic de faible résistance, assurent une liaison entre le panneau externe et la doublure sur le reste de la surface du panneau interne. [0004] In order to give a certain geometrical hold to the cover as well as a little static stiffness and inertia, a lining is glued and/or crimped at the level of the periphery of the outer panel. Wedging studs, generally made of low-strength mastic, provide a connection between the outer panel and the lining on the rest of the surface of the inner panel.
[0005] Pour limiter la vibration du capot en situation de conduite, il est connu l’emploi de renforts mécaniques fixés contre la doublure. Les renforts mécaniques également appelés renforts de doublure, sont notamment positionnés au niveau des charnières du capot. [0005] To limit the vibration of the hood in a driving situation, the use of mechanical reinforcements fixed against the lining is known. The mechanical reinforcements, also called lining reinforcements, are in particular positioned at the hinges of the hood.
[0006] Or, la présence de joint d’étanchéité de grille d’auvent, au niveau des charnières du capot, empêche les renforts de doublure de s’étendre en direction du pare-brise, au-delà des charnières de capot du véhicule automobile. En effet, pour des raisons de préservation du joint d’étanchéité, il est proscrit de souder ou bien de clincher un renfort de doublure sur ledit joint. [0006] However, the presence of a cowl grille seal, at the level of the bonnet hinges, prevents the lining reinforcements from extending towards the windshield, beyond the vehicle bonnet hinges automobile. Indeed, for reasons of preservation of the seal, it is prohibited to weld or clincher a lining reinforcement on said seal.
[0007] De ce fait, les renforts de doublure sont absents d’une zone limitrophe au joint de grille d’auvent, dénommée « zone d’interface » dans la description qui va suivre. Cette zone d interface est donc sensible au phenomene d écoulement d’air à la surface du capot. En condition de conduite, la zone d’interface peut se mettre à vibrer et engendrer un inconfort auditif pour les occupants du véhicule automobile. [0007] As a result, the lining reinforcements are absent from a zone bordering the scuttle grille joint, referred to as the "interface zone" in the description which go follow. This interface zone is therefore sensitive to the phenomenon of air flow at the surface of the cover. In driving conditions, the interface zone may begin to vibrate and cause auditory discomfort for the occupants of the motor vehicle.
[0008] L’invention vise à résoudre ce problème de vibration, en situation de conduite, d’une zone limitrophe au joint d’étanchéité de grille d’auvent d’un capot d’un véhicule automobile. [0008] The invention aims to solve this problem of vibration, in a driving situation, of a zone bordering the cowl grille seal of a bonnet of a motor vehicle.
Objet de l’invention Object of the invention
[0009] À cet effet, l’invention a pour objet un renfort de doublure pour un capot de véhicule automobile, comprenant une première partie liée à une seconde partie par l’intermédiaire d’une zone de jonction. [0009] To this end, the subject of the invention is a lining reinforcement for a motor vehicle bonnet, comprising a first part linked to a second part via a junction zone.
[0010] L’invention est remarquable en que des moyens de fixation à une doublure de capot de véhicule automobile sont présents uniquement au niveau de la première partie et de la seconde partie du renfort de doublure, et la zone de jonction s’étend le long d’un axe longitudinal et la zone de jonction est apte à se déformer de façon élastique pour permettre le pivotement de la première partie, autour d’un axe de rotation perpendiculaire ou sensiblement perpendiculaire audit axe longitudinal. [0010] The invention is remarkable in that the means for fixing to a motor vehicle bonnet lining are present only at the level of the first part and the second part of the lining reinforcement, and the junction zone extends along the along a longitudinal axis and the junction zone is able to deform elastically to allow the pivoting of the first part, around an axis of rotation perpendicular or substantially perpendicular to said longitudinal axis.
[0011] De façon avantageuse, la zone de jonction permet de lier mécaniquement deux renforts de doublure de capot, positionné de part et d’autre d’un joint de grille d’auvent, sans qu’il soit pour cela nécessaire de souder ou bien de clincher un renfort mécanique sur le joint de grille. Ainsi, le capot et l’auvent d’un véhicule automobile peuvent être renforcés mécaniquement par l’intermédiaire d’un même renfort de doublure, au plus proche d’une zone limitrophe au joint de grille d’auvent également appelée zone d’interface. De ce fait, l’invention offre une solution économique et simple de mise en œuvre pour limiter la mise en vibration de l’auvent en situation de conduite. [0011] Advantageously, the junction zone makes it possible to mechanically link two bonnet lining reinforcements, positioned on either side of a cowl grille seal, without it being necessary to weld or good to clincher a mechanical reinforcement on the grid joint. Thus, the hood and the cowl of a motor vehicle can be mechanically reinforced by means of the same lining reinforcement, closest to a zone bordering the cowl grille joint also called interface zone . As a result, the invention offers an economical and easy-to-implement solution for limiting the vibration of the awning when driving.
[0012] Selon une autre caractéristique de l’invention, la longueur de la zone de jonction, mesurée le long de l’axe longitudinal, est comprise entre 2 cm et 15 cm, de préférence entre 5 cm et 10 cm. [0013] Selon une autre caractéristique de I invention, la largeur de la zone de jonction, mesurée perpendiculairement à l’axe longitudinal, est comprise entre 2 cm et 10 cm, de préférence entre 3 cm et 6 cm. According to another characteristic of the invention, the length of the junction zone, measured along the longitudinal axis, is between 2 cm and 15 cm, preferably between 5 cm and 10 cm. [0013] According to another feature of the invention, the width of the junction zone, measured perpendicular to the longitudinal axis, is between 2 cm and 10 cm, preferably between 3 cm and 6 cm.
[0014] Selon une autre caractéristique de l’invention, l’épaisseur de la zone de jonction est comprise entre 1 cm et 3 cm, de préférence entre 1 ,5 cm et 2 cm. According to another characteristic of the invention, the thickness of the junction zone is between 1 cm and 3 cm, preferably between 1.5 cm and 2 cm.
[0015] Selon une autre caractéristique de l’invention, la zone de jonction est réalisée à partir d’un polymère synthétique. According to another characteristic of the invention, the junction zone is made from a synthetic polymer.
[0016] Selon une autre caractéristique de l’invention, la zone de jonction comporte une surépaisseur qui s’étend parallèlement ou sensiblement parallèlement à l’axe longitudinal. [0016] According to another characteristic of the invention, the junction zone comprises an extra thickness which extends parallel or substantially parallel to the longitudinal axis.
[0017] L’invention concerne également un véhicule automobile comprenant un renfort de doublure tel que décrit ci-dessus, comprenant une première partie du renfort de doublure fixé à une doublure du capot du véhicule automobile, et une seconde partie du renfort fixée à l’auvent du véhicule automobile. [0017] The invention also relates to a motor vehicle comprising a lining reinforcement as described above, comprising a first part of the lining reinforcement fixed to a lining of the hood of the motor vehicle, and a second part of the reinforcement fixed to the motor vehicle cowl.
[0018] Selon une variante de réalisation, la zone de jonction enjambe un joint de grille de l’auvent. [0018]According to a variant embodiment, the junction zone spans a grille joint of the awning.
[0019] Selon une variante de réalisation, la zone de jonction s’étend le long d’un axe longitudinal, l’axe longitudinal est perpendiculaire ou sensiblement perpendiculaire au joint de grille d’auvent au niveau du joint de grille d’auvent enjambé par la zone de jonction. [0019]According to a variant embodiment, the junction zone extends along a longitudinal axis, the longitudinal axis being perpendicular or substantially perpendicular to the cowl grille joint at the level of the spanned cowl grille joint through the junction area.
[0020] Selon une variante de réalisation, la première partie du renfort de doublure est fixée au niveau d’une charnière de capot. [0020]According to a variant embodiment, the first part of the lining reinforcement is fixed at the level of a bonnet hinge.

Description des figures Description of figures
[0022] L’invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d’exemple non limitatif et faite en se référant aux dessins dans lesquels : The invention will be better understood on reading the following description, given solely by way of non-limiting example and made with reference to the drawings in which:
[0023] [Fig. 1] représente une vue en perspective et partielle d’un véhicule automobile comportant un renfort de doublure selon l’invention, dont une première partie est fixée au capot du véhicule automobile et une seconde partie est fixée à l’auvent dudit véhicule. Description detaillee de l’invention [0023] [Fig. 1] shows a perspective and partial view of a motor vehicle comprising a lining reinforcement according to the invention, a first part of which is fixed to the hood of the motor vehicle and a second part is fixed to the cowl of said vehicle. Detailed description of the invention
[0024] Pour rappel, l’invention propose un renfort de doublure permettant d’atténuer les vibrations, en situation de conduite, au niveau d’une zone limitrophe au joint d’étanchéité d’une grille d’auvent d’un véhicule automobile. As a reminder, the invention proposes a lining reinforcement making it possible to attenuate the vibrations, in a driving situation, at the level of a zone bordering on the sealing joint of a cowl grille of a motor vehicle. .
[0025] Pour cela, comme illustré par la figure 1 , un renfort de doublure 2 selon l’invention se compose d’une première partie 4 liée à une seconde partie 6 par l’intermédiaire d’une zone de jonction 8. [0025] For this, as illustrated in Figure 1, a lining reinforcement 2 according to the invention consists of a first part 4 linked to a second part 6 via a junction zone 8.
[0026] Selon le présent exemple, la première partie 4, la seconde partie 6 et la zone de jonction 8 sont réalisées à partir d’un même matériau, tel qu’un polymère synthétique. According to this example, the first part 4, the second part 6 and the junction zone 8 are made from the same material, such as a synthetic polymer.
[0027] La première partie 4 ainsi que la seconde partie 6 comportent des moyens de fixation 10 du renfort de doublure à un support de type doublure de capot et/ou capot pour véhicule automobile. Selon le présent exemple, les moyens de fixation se composent d’appendices, comportant chacun une extrémité libre destinée à s’insérer dans un logement ménagé à cet effet, dans un capot ou dans un auvent de véhicule automobile. Comme illustré par la figure 1 , les moyens de fixation 10 permettent par une technique de clinchage, le maintien de la première partie 4 du renfort de doublure 2 contre une doublure 12 de capot, et le maintien de la seconde partie 6 contre un auvent 14 d’un véhicule automobile. The first part 4 and the second part 6 comprise means 10 for fixing the lining reinforcement to a support of the hood lining type and/or hood for a motor vehicle. According to the present example, the fastening means consist of appendages, each comprising a free end intended to be inserted into a housing provided for this purpose, in a bonnet or in a motor vehicle cowl. As illustrated in Figure 1, the fastening means 10 allow, by a clinching technique, the maintenance of the first part 4 of the lining reinforcement 2 against a hood lining 12, and the maintenance of the second part 6 against a canopy 14 of a motor vehicle.
[0028] Il est à noter que la première partie 4 comporte également des passages permettant l’insertion de vis de fixation 16 maintenant une charnière au capot 18. Ainsi, la première partie 4 du renfort de doublure est maintenue au capot au niveau d’une charnière. It should be noted that the first part 4 also includes passages allowing the insertion of fixing screws 16 holding a hinge to the cover 18. Thus, the first part 4 of the lining reinforcement is held to the cover at the level of a hinge.
[0029] De façon avantageuse, la première partie 4 et la seconde partie 6 du renfort de doublure sont liées par la zone de jonction 8. La zone de jonction s’étend le long d’une direction le long d’un axe longitudinal AA’, sur une longueur comprise entre 2 cm et 15 cm, de préférence entre 5 cm et 10 cm. La largeur de la zone de jonction 8, mesurée perpendiculairement à l’axe longitudinal, est comprise entre 2 cm et 10 cm, de préférence entre 3 cm et 6 cm. L’épaisseur de la zone de jonction est comprise entre 1 cm et 3 cm, de préférence entre 1 ,5 cm et 2 cm. [0030] Selon le présent exemple, la zone de jonction comporte une surépaisseur 20 qui s’étend parallèlement ou sensiblement parallèlement à l’axe longitudinal AA’. Advantageously, the first part 4 and the second part 6 of the lining reinforcement are linked by the junction zone 8. The junction zone extends along a direction along a longitudinal axis AA ', over a length of between 2 cm and 15 cm, preferably between 5 cm and 10 cm. The width of the junction zone 8, measured perpendicular to the longitudinal axis, is between 2 cm and 10 cm, preferably between 3 cm and 6 cm. The thickness of the junction zone is between 1 cm and 3 cm, preferably between 1.5 cm and 2 cm. According to the present example, the junction zone comprises an extra thickness 20 which extends parallel or substantially parallel to the longitudinal axis AA'.
[0031] Le renfort de doublure est agencé de sorte que la zone de jonction 8 enjambe un joint de grille 22 de l’auvent 14 et permet le pivotement de la première partie par rapport à la seconde partie, afin que les parties soient solidaires par l’intermédiaire de la zone de jonction, lorsque le capot est ouvert ou fermé. [0031] The lining reinforcement is arranged so that the junction zone 8 spans a grid joint 22 of the canopy 14 and allows the pivoting of the first part relative to the second part, so that the parts are integral by through the junction zone, when the cover is open or closed.
[0032] Ainsi, le capot et l’auvent d’un véhicule automobile peuvent être renforcés mécaniquement par l’intermédiaire d’un même renfort de doublure, au plus proche d’une zone limitrophe au joint de grille d’auvent. De ce fait, l’invention offre une solution économique et simple de mise en œuvre pour limiter la mise en vibration de l’auvent en situation de conduite. [0032] Thus, the hood and the cowl of a motor vehicle can be mechanically reinforced by means of the same lining reinforcement, as close as possible to a zone bordering the cowl grille joint. As a result, the invention offers an economical and easy-to-implement solution for limiting the vibration of the awning when driving.
