Description
ARMATURE SUPPORT DE PARE-CHOCS POUR LA FACE AVANT D'UN VEHICULE AUTOMOBILE La présente invention concerne une armature support de pare-chocs pour la face avant d'un véhicule automobile ainsi que le véhicule équipé d'une telle armature support de pare-chocs. Des véhicules équipés d'une armature support de pare-chocs sont déjà connus dans l'art antérieur et sont généralement satisfaisants en utilisation. En particulier, ils doivent garantir une bonne tenue lors d'un choc dit de réparabilité. Ce choc connu sous le nom de « Bumper test R-CAR » est un choc centré sur le pare-chocs à une vitesse de 10 +/- 0,5 km/h. Lors d'un tel choc, l'objectif est de ne pas devoir intervenir sur la façade avant au niveau du groupe moto-ventilateur encore appelé groupe GMV. On conserve ainsi une réparabilité qui se limite au pare-chocs, à l'armature support et on doit éviter tout contact avec le GMV situé juste derrière dans le sens d'avancée du véhicule.The present invention relates to a bumper support frame for the front face of a motor vehicle and to the vehicle equipped with such a bumper support frame. BACKGROUND OF THE INVENTION . Vehicles equipped with a bumper support frame are already known in the prior art and are generally satisfactory in use. In particular, they must ensure good performance during a so-called repairability shock. This shock known as "Bumper test R-CAR" is a shock centered on the bumper at a speed of 10 +/- 0.5 km / h. During such a shock, the objective is not to have to intervene on the front panel at the motorcycle fan group still called GMV group. This retains a repairability which is limited to the bumper, the support frame and must avoid contact with the GMV located just behind in the direction of advance of the vehicle.
Par ailleurs, lors d'un choc piéton, encore appelé choc fémur, il est fréquent que l'armature support, suite à une sollicitation selon l'axe Z, s'affaisse en direction de la traverse, ce qui entraîne également le pare-chocs. Ceci augmente les risques de blessures du piéton qui peut alors heurter certains éléments de structure ou des équipements disposés derrière le pare-chocs du véhicule. Ainsi pour garantir à la fois une bonne tenue en cas de choc dit de réparabilité et en cas de choc piéton, on a proposé de fixer l'armature sur la traverse avant qui s'étend entre deux longerons, tout en préservant une certaine fusibilité de l'élément de maintien de l'armature permettant ainsi de réduire au maximum l'effort fémur. On obtient ainsi un compromis satisfaisant entre le choc de réparabilité et le choc piéton grâce à un bonne tenue en flexion de l'élément de maintien d'armature fixé sur la traverse tandis qu'il est possible de définir une zone du pied plus faible permettant ainsi de limiter les efforts en Z.Furthermore, during a pedestrian impact, also called femoral shock, it is common for the support armature, following a Z-axis bias, to sag towards the cross-member, which also causes shocks. This increases the risk of injury to the pedestrian who can then hit some structural elements or equipment arranged behind the bumper of the vehicle. Thus, to guarantee both a good resistance in the event of a so-called repairability shock and in the event of a pedestrian impact, it has been proposed to fix the reinforcement on the front cross member which extends between two longitudinal members, while preserving a certain degree of fusibility. the element for maintaining the armature thus making it possible to reduce the femur force as much as possible. A satisfactory compromise is thus obtained between the repairability shock and the pedestrian impact thanks to a good bending strength of the reinforcement holding element fixed to the cross-member while it is possible to define a weaker zone of the foot allowing thus to limit the efforts in Z.
Cependant sur certains véhicules, il n'est pas possible de fixer l'armature support sur la traverse avant du fait notamment d'un jeu trop faible entre cette traverse et le GMV. Aussi, lors d'un choc réparabilité, la traverse avant fléchie et l'armature de support qui est positionnée à cheval sur cette traverse entre en contact avec le GMV et le détériore ce qui engendre des réparations supplémentaires.However, on some vehicles, it is not possible to fix the support frame on the front cross member, in particular due to a too weak clearance between this crossbar and the GMV. Also, during a repairable shock, the front cross bent and the support frame which is positioned astride this cross comes into contact with the GMV and deteriorates which causes additional repairs.
Ainsi, dans FR 2 900 617, on a proposé un véhicule comprenant une structure comportant deux longerons et une traverse, ladite traverse venant se fixer par ses extrémités aux deux longerons, et une armature support s'étendant au-dessus de ladite traverse, destinée à recevoir un pare-chocs. Entre ladite armature support et ladite traverse sont interposés des moyens de maintien destinés à limiter l'affaissement de l'armature sur la traverse en cas de choc. Ces moyens de maintien appartenant à l'armature comprennent au moins un pied qui s'étend de façon sensiblement perpendiculaire à l'axe longitudinal du véhicule et qui comporte une surface d'appui, destinée à reposer sur la partie supérieure de la traverse, et qui est prolongée par une patte en saillie venant en butée contre un côté latéral de la traverse sur la face avant de celle-ci. On a pu remarquer que cette structure de la jambe ou pied d'armature favorise le choc fémur puisqu'elle «affaiblit » le pied d'armature réduisant l'effort en Z. Cependant, cette forme entraîne, lors d'un choc réparabilité, une cassure du pied d'armature et là encore un endommagement du groupe GMV survient notamment lorsque les écarts entre GMV et traverse sont réduits.Thus, in FR 2 900 617, there has been proposed a vehicle comprising a structure comprising two longitudinal members and a cross member, said crossbar being fixed at its ends to the two longitudinal members, and a support armature extending above said cross member, intended to receive a bumper. Between said support frame and said cross member are interposed holding means for limiting the collapse of the frame on the cross member in case of impact. These holding means belonging to the frame comprise at least one foot which extends substantially perpendicular to the longitudinal axis of the vehicle and which comprises a bearing surface, intended to rest on the upper part of the crossbar, and which is extended by a projecting lug abutting against a lateral side of the cross member on the front face thereof. It has been noted that this structure of the leg or foot reinforcement promotes femoral shock since it "weakens" the reinforcement foot reducing the effort in Z. However, this form causes, in a repairable shock, a breaking of the reinforcing foot and again damage to the GMV group occurs especially when the differences between GMV and cross are reduced.
La présente invention a donc pour but de proposer une armature support de pare-chocs qui pallie les inconvénients cités de l'art antérieur. A cet effet, l'invention a pour objet une armature support de pare-chocs pour la face avant d'un véhicule automobile présentant au moins un pied dont l'extrémité libre présente une surface d'appui destinée à venir se positionner sur la face supérieure d'une traverse, ladite surface d'appui étant prolongée d'une patte en saillie propre à épouser une autre face de la traverse, caractérisé en ce que ledit pied comporte un élément de renfort qui s'étend le long du pied, depuis l'armature jusqu'à l'extrémité dudit pied, cet élément de renfort limitant la déformation du pied en cas de choc dit de réparabilité sur la face avant du véhicule.The present invention therefore aims to provide a bumper support frame which overcomes the disadvantages mentioned in the prior art. For this purpose, the invention relates to a bumper support frame for the front face of a motor vehicle having at least one foot whose free end has a bearing surface intended to be positioned on the face upper of a crossbar, said bearing surface being extended by a projecting lug adapted to match another face of the cross, characterized in that said foot comprises a reinforcing element which extends along the foot, since the reinforcement to the end of said foot, this reinforcing element limiting the deformation of the foot in case of shock known as repairability on the front of the vehicle.
De préférence, l'élément de renfort est constitué d'un matériau présentant une résistance mécanique supérieure à celle du matériau constituant le pied de l'armature. Ainsi, de manière avantageuse, lors d'un choc dit de réparabilité, le pied de l'armature qui est de préférence le pied central va se casser ou à tout le moins se déformer tandis que l'élément de renfort du fait de sa résistance mécanique supérieure à celle du pied ne se casse pas et permet de contenir la déformation dudit pied de l'armature support de pare-chocs et évite ainsi un impact du GMV par le pied cassé ou déformé.Preferably, the reinforcing element is made of a material having a mechanical strength greater than that of the material constituting the foot of the armature. Thus, advantageously, during a so-called repairability shock, the foot of the armature which is preferably the central foot will break or at least deform while the reinforcing element because of its strength. mechanical superior to that of the foot does not break and can contain the deformation of said foot of the bumper support frame and thus avoids an impact of the GMV by the broken or deformed foot.
Selon une forme de réalisation préférée de l'invention, l'élément de renfort se présente sous forme d'un élément filaire s'étendant entre la jonction du pied et de l'armature support de pare-choc jusqu'à l'extrémité de la patte en saillie dudit pied. De préférence, l'armature et le pied sont réalisés d'une seule pièce en une matière plastique telle qu'une polyoléfine comme un homopolymère de polypropylène, par exemple renforcé de fibres de verre comme celui connu sous la dénomination commerciale « Hostacom », l'élément de renfort étant constitué d'une matière de résistance supérieure telle que du métal, un alliage ou une matière synthétique de résistance élevée telle que du nylon par exemple, de sorte que sous l'effet d'un choc, le pied peut se déformer et même se rompre tandis que l'élément de renfort résiste au choc et maintient le pied rompu sous forme d'une pièce. Selon une variante de réalisation, l'élément de renfort se présente sous la forme d'une bande s'étendant entre la jonction du pied et de l'armature support de pare-choc jusqu'à l'extrémité de la patte en saillie dudit pied. L'invention permet de réduire les efforts « choc Fémur » grâce à la fragilisation du pied central d'armature qui peut présenter une diminution de sa section, par exemple avec une section transversale en U, tout en garantissant une protection du GMV lors du choc dit de réparabilité du fait de l'élément de renfort présent. L'invention permet de ne prévoir qu'un seul pied central en offrant ainsi un gain de matière et de masse tout en étant peu coûteuse du fait de l'utilisation d'un élément de renfort filaire ou en bande résistant au choc et dont la mise en place en production est rapide puisqu'il suffit de tendre le fil pour le mettre en place. L'armature de support de pare chocs permet de conserver une classe réparabilité à coût limité. On décrira maintenant l'invention plus en détails en référence au dessin dans lequel : Les figures I a et 1 b représentent une vue en coupe de la partie avant d'un véhicule selon l'état de la technique avant et après un choc dit de réparabilité. La figure 2 représente une vue arrière d'une structure avant selon l'invention ; La figure 3 représente une vue en coupe de la partie avant d'un véhicule selon l'invention après un choc dit de réparabilité.According to a preferred embodiment of the invention, the reinforcing element is in the form of a wire element extending between the junction of the foot and the bumper support frame to the end of the tab projecting from said foot. Preferably, the armature and the foot are made in one piece from a plastic material such as a polyolefin such as a homopolymer of polypropylene, for example reinforced with glass fibers, such as that known under the trade name "Hostacom", l. reinforcing member being made of a superior resistance material such as metal, alloy or high strength synthetic material such as nylon for example, so that under impact, the foot can deform and even break while the reinforcing element resists shock and keeps the broken foot in the form of a piece. According to an alternative embodiment, the reinforcing element is in the form of a strip extending between the junction of the foot and the bumper support frame to the end of the protruding tab of said foot. The invention makes it possible to reduce the "femur shock" forces by weakening the central armature foot which may have a reduction in its section, for example with a U-shaped cross section, while guaranteeing protection for the GMV during the impact. said repairability because of the reinforcement element present. The invention makes it possible to provide only one central foot, thus offering a saving in material and mass while being inexpensive due to the use of a wired or shock-resistant reinforcing element and whose setting up in production is fast since it is enough to stretch the wire to put it in place. The bumper support frame makes it possible to maintain a reparability class at a limited cost. The invention will now be described in more detail with reference to the drawings in which: FIGS. 1a and 1b show a sectional view of the front part of a vehicle according to the state of the art before and after a so-called shock of repairability. Figure 2 shows a rear view of a front structure according to the invention; Figure 3 shows a sectional view of the front portion of a vehicle according to the invention after a shock called repairability.
Comme on peut le voir en partie sur la figure I a, la façade avant d'un véhicule automobile comprend de manière classique un pare-chocs (non représenté) en matières plastiques. La partie supérieure de ce pare-chocs est fixée sur une armature support de pare-chocs 4 tandis que sa partie inférieure est portée par une poutre de pare-chocs encore appelée poutre de réparabilité. Cette poutre de pare-chocs comprend de manière classique une traverse avant 2 s'étendant transversalement au véhicule entre deux longerons L.As can be seen in part in Figure Ia, the front face of a motor vehicle conventionally comprises a bumper (not shown) of plastics. The upper part of this bumper is fixed on a bumper support frame 4 while its lower part is carried by a bumper beam also called repair beam. This bumper beam conventionally comprises a front cross member 2 extending transversely to the vehicle between two longitudinal members L.
L'armature support de pare-chocs 4 comprend un pied central 1 qui s'étend perpendiculairement à la direction d'avancée du véhicule (représentée par la flèche X) et qui est fixé sur la traverse avant 2. De manière à réduire au maximum l'effort choc fémur suite à une sollicitation selon l'axe Z (axe vertical par rapport au véhicule), le pied central 1 présente une section transversale en forme de U, la base du U étant positionnée du côté de l'avant du véhicule. Toutefois pour garantir une bonne tenue au choc réparabilité, l'extrémité libre de ce pied central 1 présente une surface d'appui sur la traverse avant ou poutre de réparabilité 2 et présente ainsi une face d'appui 11 ménagée à son extrémité et reposant sur la face supérieure 21 de la traverse avant 2 ainsi qu'une patte 12 en saillie de ladite face 11 de manière à reposer contre la face avant 22 de la traverse 2 en position montée.The bumper support frame 4 comprises a central foot 1 which extends perpendicularly to the direction of advance of the vehicle (represented by the arrow X) and which is fixed on the front cross member 2. In order to reduce as much as possible the femoral shock force following a bias along the Z axis (vertical axis relative to the vehicle), the central leg 1 has a U-shaped cross section, the base of the U being positioned on the side of the front of the vehicle . However, to guarantee a good resistance to repairable shock, the free end of this central foot 1 has a bearing surface on the front cross member or repair beam 2 and thus has a bearing face 11 formed at its end and resting on the upper face 21 of the front cross member 2 and a lug 12 projecting from said face 11 so as to rest against the front face 22 of the cross member 2 in the mounted position.
Or, lors d'un choc dit de réparabilité également connu sous la dénomination « Bumper test R-Car avant » et qui est réalisé selon les critères suivants : vitesse de 10 +/- 0,5 km/h, mannequin conducteur de 75 kg, véhicule roulant en avant, centrage sur le pare-chocs avec +/- 50 mm et une garde au sol de 455 mm (+/- 3 mm), on remarque que le GMV est impacté par le choc.However, during a so-called repairability shock also known under the name "Bumper test R-Car before" and which is carried out according to the following criteria: speed of 10 +/- 0.5 km / h, conductive manikin of 75 kg , vehicle traveling forward, centering on the bumper with +/- 50 mm and a ground clearance of 455 mm (+/- 3 mm), we note that the GMV is impacted by the shock.
Comme on peut le voir sur la figure 1 b, la traverse avant 2 a fléchie vers l'arrière sous l'effet du choc et le pied central 1 sous l'effet de ce même choc s'est cassé en deux pièces qui sont alors venues buter contre le GMV situé derrière, endommageant ce dernier.As can be seen in FIG. 1b, the front cross member 2 has bent backwards under the effect of the impact and the central foot 1 under the effect of this same impact has broken into two pieces which are then come against the GMV behind, damaging it.
L'invention propose que le pied central 1 comprenne un élément de renfort 3 permettant de contenir et limiter la déformation de ce pied 1 vers le GMV lors d'un choc à 10 km/h. Cet élément de renfort 3 est avantageusement constitué d'un élément filaire ou fil de renfort tendu le long du pied central 2 depuis l'armature support 4 jusqu'à l'extrémité de la patte d'appui 12 dudit pied central 1 sur la face avant de la traverse 2. Ce fil tendu 3 est réalisé en un matériau dont la résistance est plus élevée que celle du matériau constituant le pied central 1 de sorte que, lors d'un choc, ce fil tendu 3 qui ne se rompt pas, contient les deux parties du pied central 1 résultant de sa cassure sous l'effet du choc et évite leur déplacement vers le GMV. L'invention entre alors en action. En effet, le fil tendu 3 à l'intérieur du pied 1 d'armature permet le maintien des deux parties du pied 1 d'armature afin d'éviter tout contact avec le GMV (cf. la figure 3).The invention proposes that the central leg 1 comprises a reinforcing element 3 for containing and limiting the deformation of this foot 1 to the GMV during an impact at 10 km / h. This reinforcing element 3 is advantageously constituted by a wire element or reinforcement wire stretched along the central foot 2 from the support armature 4 to the end of the support lug 12 of said central foot 1 on the face 2. This stretched wire 3 is made of a material whose resistance is higher than that of the material constituting the central foot 1 so that, during an impact, the tensioned wire 3 which does not break, contains the two parts of the central foot 1 resulting from its breaking under the effect of the shock and prevents their movement towards the GMV. The invention then comes into action. Indeed, the stretched wire 3 inside the foot 1 of reinforcement allows the maintenance of the two parts of the foot 1 of reinforcement to avoid contact with the GMV (see Figure 3).
Ainsi, lors d'un choc du véhicule avec le Bumper test R-CAR, le pare-chocs entre en contact avec l'armature de pare-chocs 4 qui se déforme et le pied central 1 se rompt du fait de sa faible section.Thus, during a collision of the vehicle with the Bumper test R-CAR, the bumper comes into contact with the bumper frame 4 which is deformed and the central foot 1 breaks due to its small section.
L'élément de renfort 3 qui est bouterollé ou soudé sur la partie supérieure du pied central 1 au niveau de la jonction avec l'armature support de pare-chocs 4 et qui s'étend ensuite le long dudit pied central 1 jusqu'à l'extrémité de la patte d'appui 12 dudit pied central 1, résiste au choc et ne se rompt pas, de sorte que cet élément de renfort permet de contenir le déplacement vers l'arrière des deux parties du pied central 1 résultant de la cassure de celui- ci et de fait, de contenir la déformation de ce pied central 1, l'empêchant notamment d'endommager le GMV Cet élément de renfort est de préférence un élément filaire ou fil tendu 3 qui peut donc être bouterollé (c'est-à-dire soudé dans un noyau de plastique fondu) sur l'armature support de pare-chocs 4 au niveau de la jonction du pied central 1 avec l'armature support de pare- chocs 4 et s'étendre le long du pied central 1 jusqu'à l'extrémité de la patte d'appui 12 où il est maintenu par son extrémité dans une encoche 5 ménagée dans la patte d'appui 12. L'élément de renfort filaire 3 peut être intégré lors du moulage en une pièce du pied central 1 et de l'armature support de pare-chocs 4.The reinforcing element 3 which is riveted or welded on the upper part of the central foot 1 at the junction with the bumper support frame 4 and which then extends along said central foot 1 to end of the support lug 12 of said central foot 1, resists the shock and does not break, so that this reinforcing element can contain the rearward movement of the two parts of the central leg 1 resulting from the break of the latter and in fact, to contain the deformation of the central foot 1, preventing it in particular from damaging the GMV. This reinforcement element is preferably a wire element or stretched wire 3 which can therefore be riveted (this is that is welded in a molten plastic core) on the bumper support frame 4 at the junction of the central foot 1 with the bumper support frame 4 and extend along the central foot 1 to the end of the support leg 12 where it is maintained by its extr moth-eaten in a slot 5 formed in the support bracket 12. The wire reinforcing member 3 may be incorporated during molding in one piece of the pillar 1 and the bumper support frame 4.
Cet élément filaire 3 peut être un élément filaire en métal ou en alliages métalliques ou même un élément filaire en matière synthétique tel qu'un élément filaire en nylon, ce matériau constituant l'élément filaire de renfort 3 devant présenter une résistance mécanique supérieure à celle du matériau constituant le pied central de l'armature support de pare- chocs 4, c'est-à-dire résistant à un choc à 10 km/h. L'armature support de pare-chocs 4 selon l'invention permet non seulement d'éviter un contact entre ladite armature 4 et le GMV mais également de rompre au niveau du pied central 1 ce qui permet une chute d'efforts et donc une amélioration des critères biomécaniques en choc fémur tout en garantissant le choc de réparabilité.This wire element 3 can be a wire element made of metal or metal alloys or even a wire element made of synthetic material such as a wire element made of nylon, this material constituting the wire reinforcing element 3 having to have a mechanical strength greater than that the material constituting the central leg of the bumper support frame 4, that is to say, resistant to impact at 10 km / h. The bumper support frame 4 according to the invention not only makes it possible to avoid contact between said armature 4 and the GMV but also to break at the level of the central foot 1, which allows a fall in effort and therefore an improvement. biomechanical criteria in femur shock while guaranteeing the shock of repairability.
