Abstract
Description
La présente invention concerne un pare-chocs en matière thermoplastique muni d'un bouclier à poutre intégrée. The present invention relates to a bumper made of thermoplastic material provided with an integrated beam shield.
On connaît déjà des pare-chocs en matière thermoplastique du type dans lequel on rapporte, à l'intérieur du bouclier du pare-chocs, une poutre de renfort qui prend appui sur les longerons du véhicule. There are already known bumpers of thermoplastic material of the type in which there is reported, inside the bumper shield, a reinforcing beam which bears on the side members of the vehicle.
Cette poutre a pour fonction de résister à des chocs frontaux subis par le pare-chocs. The function of this beam is to resist frontal impacts to the bumper.
Ces pare-chocs, qui sont réalisés en deux parties à savoir, le bouclier d'une part et la poutre d'autre part, lesquels doivent être assemblés l'un à l'autre, présentent l'inconvénient d'être relativement coûteux à fabriquer. These bumpers, which are made in two parts, namely the shield on the one hand and the beam on the other hand, which must be assembled to each other, have the disadvantage of being relatively expensive to to manufacture.
On a déjà cherché à réduire ce coût en moulant une poutre en matière thermoplastique d'un seul tenant avec le bouclier. We have already sought to reduce this cost by molding a thermoplastic beam in one piece with the shield.
Mais cette solution ne donne pas satisfaction car la poutre est alors réunie au bouclier par des nervures qui font apparaître des retassures sur la face extérieure ou peau du bouclier. Ces retassures nuisent à l'esthétique du pare-chocs. But this solution is not satisfactory because the beam is then joined to the shield by ribs which reveal recesses on the outer face or skin of the shield. These shrinkages affect the aesthetics of the bumper.
La présente invention vise à proposer un nouveau bouclier de pare-chocs comprenant une poutre intégrée, c'est-à-dire une poutre issue directement de moulage avec le bouclier, sans que cette dernière ne présente de retassure sur sa face visible. The present invention aims to propose a new bumper shield comprising an integrated beam, that is to say a beam resulting directly from molding with the shield, without the latter having any shrinkage on its visible face.
La présente invention a pour objet un pare-chocs en matière thermoplastique muni d'un bouclier en matière thermoplastique et d'une poutre de renfort également en matière thermoplastique qui est caractérisé par le fait que le bouclier comporte une ouverture longitudinale et que la poutre est solidaire du bouclier par les bords de cette ouverture. The present invention relates to a bumper made of thermoplastic material provided with a shield made of thermoplastic material and a reinforcement beam also made of thermoplastic material which is characterized in that the shield has a longitudinal opening and that the beam is secured to the shield by the edges of this opening.
Ainsi, le pare-chocs selon l'invention comporte un bouclier et une poutre issus du même moulage avec la même matière thermoplastique. Thus, the bumper according to the invention comprises a shield and a beam from the same molding with the same thermoplastic material.
Néanmoins, à la différence des pare-chocs connus, le bouclier du pare-chocs selon l'invention ne présente pas de retassure sur sa face visible ou peau, car la poutre se raccorde au bouclier par une continuité de paroi le long des bords de l'ouverture longitudinale du bouclier. However, unlike known bumpers, the bumper shield according to the invention does not have any shrinkage on its visible face or skin, since the beam is connected to the shield by a wall continuity along the edges of the longitudinal opening of the shield.
Il suffit ensuite d'obturer cette ouverture longitudinale en rapportant un cache ou un plastron de forme appropriée sur la peau du bouclier. It then suffices to close this longitudinal opening by fitting a cover or a bib of appropriate shape to the skin of the shield.
Ce cache est avantageux en ce qu'il permet d'obtenir des effets esthétiques particuliers, soit parce qu'il peut être d'une couleur différente du bouclier, soit tout simplement parce qu'il est plus facile à peindre et ne requiert pas notamment d'opération de marouflage, qui est nécessaire pour un bouclier de pare-chocs. This cover is advantageous in that it makes it possible to obtain particular aesthetic effects, either because it can be of a different color from the shield, or quite simply because it is easier to paint and does not require in particular masking operation, which is necessary for a bumper shield.
En outre, en cas de petits chocs, on peut remplacer uniquement le cache, ce qui réduit considérablement le coût de la réparation. In addition, in the event of small impacts, only the cover can be replaced, which considerably reduces the cost of repair.
Le pare-chocs selon l'invention présente en outre une bonne rigidité qu'il doit notamment au fait que la poutre est très intimement liée au bouclier de sorte que l'inertie de ces deux pièces est supérieure à celle obtenue en les disposant l'une derrière l'autre sans les relier ou les reliant ponctuellement l'une à l'autre. The bumper according to the invention also has good rigidity which it owes in particular to the fact that the beam is very intimately linked to the shield so that the inertia of these two parts is greater than that obtained by arranging them. one behind the other without connecting them or occasionally connecting them to each other.
Conformément à l'invention, on peut structurer la poutre en fonction des propriétés mécaniques que l'on désire conférer au pare-chocs sans que cela n'ait d'incidence sur l'esthétique du bouclier dont la peau demeure exempte de retassure. In accordance with the invention, the beam can be structured as a function of the mechanical properties which it is desired to impart to the bumper without this having any effect on the aesthetics of the shield, the skin of which remains free of shrinkage.
C'est ainsi que, selon un premier mode de réalisation de l'invention, on réalise un nervurage de la poutre en densifiant ce nervurage dans la région correspondant aux longerons du véhicule sur lesquels la poutre vient prendre appui en cas de chocs. Thus, according to a first embodiment of the invention, a ribbing of the beam is produced by densifying this ribbing in the region corresponding to the side members of the vehicle on which the beam comes to bear in the event of impacts.
Selon un second mode de réalisation de l'invention, on réalise, sur la face de la poutre opposée au bouclier, des organes absorbeurs de chocs en regard des longerons du véhicule. According to a second embodiment of the invention, shock absorbing members are produced on the face of the beam opposite the shield opposite the side members of the vehicle.
De tels organes peuvent être par exemple réalisés sous la forme d'enceintes de confinement qui sont des enveloppes cylindriques ou prismatiques, de section par exemple circulaire ou rectangulaire, faisant saillie de la face de la poutre opposée au bouclier et ouvertes sur leur face opposée au bouclier, enceintes de confinement dans lesquelles on place des absorbeurs de chocs sous la forme de structures en nid d'abeilles ou de blocs de matériau compressible, par exemple du type mousse PPE. En dépassant des enceintes de confinement, ces absorbeurs de chocs s'appuient sur les longerons ou sur des éléments intermédiaires de liaison avec ceux-ci et travaillent axialement en cas de choc, ce qui leur permet d'absorber plus efficacement l'énergie du choc transmise par la poutre. Such members can for example be made in the form of containment chambers which are cylindrical or prismatic envelopes, of circular or rectangular section for example, projecting from the face of the beam opposite the shield and open on their face opposite to the shield, containment enclosures in which shock absorbers are placed in the form of honeycomb structures or blocks of compressible material, for example of the PPE foam type. By exceeding containment enclosures, these shock absorbers are supported on the side members or on intermediate connecting elements with these and work axially in the event of an impact, which allows them to more effectively absorb the energy of the impact transmitted by the beam.
I1 faut rappeler en effet que la poutre peut travailler en flexion par appui sur les longerons du véhicule en étant initialement droite ou cintrée, ce qui produit un effet de voûte. It must be remembered that the beam can work in bending by pressing on the side members of the vehicle while being initially straight or curved, which produces an arch effect.
Néanmoins, la poutre peut également travailler en compression par appui sur une traverse du véhicule. Dans un tel cas, il est opportun de prévoir une structure de poutre telle que sa face dirigée vers ladite traverse joue le rôle d'absorbeur de chocs. However, the beam can also work in compression by pressing on a cross member of the vehicle. In such a case, it is expedient to provide a beam structure such that its face directed towards said crosspiece acts as a shock absorber.
La poutre peut également travailler en mode mixte en fléchissant d'abord jusqu'à s'appliquer longitudinalement contre la traverse, puis en se comprimant contre ladite traverse. The beam can also work in mixed mode by first bending until it is applied longitudinally against the cross member, then by compressing against said cross member.
Selon un troisième mode de réalisation de l'invention, on réalise la poutre en surmoulant une feuille de renfort du type constitué par un tissé ou un non tissé de fibres de renfort, notamment en verre, mélangées à de la matière thermoplastique, ladite matiere thermoplastique étant présente sous la forme de fibres de matière thermoplastique, comme dans le matériau vendu sous la dénomination Twintex par la société VETROTEX, ou étant présente par imprégnation des fibres de renfort, comme dans les matériaux de la famille des thermoplastiques renforcés estampables (TRE). According to a third embodiment of the invention, the beam is produced by overmolding a reinforcing sheet of the type consisting of a woven or a nonwoven of reinforcing fibers, in particular glass, mixed with thermoplastic material, said thermoplastic material. being present in the form of fibers of thermoplastic material, as in the material sold under the name Twintex by the company VETROTEX, or being present by impregnation of reinforcing fibers, as in materials of the family of stampable reinforced thermoplastics (TRE).
Bien entendu, les trois modes de réalisations décrits ci-dessus ne s'excluent pas mutuellement. Of course, the three embodiments described above are not mutually exclusive.
Il est à noter que le bouclier selon l'invention, outre qu'il est particulièrement économique à réaliser tout en présentant une bonne rigidité, présente également l'avantage de pouvoir être injecté avec des longueurs de flux réduites, ce qui améliore la qualité de l'injection et permet à la fois de réduire le cycle de moulage du bouclier et de simplifier le bloc chaud du moule par lequel la matière plastique est introduite dans le moule. It should be noted that the shield according to the invention, in addition to being particularly economical to produce while having good rigidity, also has the advantage of being able to be injected with reduced flow lengths, which improves the quality of injection and allows both to reduce the shield molding cycle and to simplify the hot block of the mold by which the plastic is introduced into the mold.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple non limitatif en référence au dessin annexé dans lequel
- la figure 1 est une vue en perspective d'un pare-chocs selon un premier mode de réalisation de l'invention,
- la figure 2 est une vue analogue à la figure 1 montrant le pare-chocs en cours de moulage,
- la figure 3 est une vue en perspective d'un pare-chocs selon un deuxième mode de réalisation de l'invention,
- la figure 4 est une vue de derrière du pare-chocs de la figure 3,
- les figures 5 à 8 sont des vues en coupe selon C-C de la figure 1.In order to better understand the invention, we will now describe an embodiment given by way of non-limiting example with reference to the accompanying drawing in which
FIG. 1 is a perspective view of a bumper according to a first embodiment of the invention,
FIG. 2 is a view similar to FIG. 1 showing the bumper during molding,
FIG. 3 is a perspective view of a bumper according to a second embodiment of the invention,
FIG. 4 is a rear view of the bumper of FIG. 3,
- Figures 5 to 8 are sectional views along CC of Figure 1.
Le pare-chocs de la figure 1 comprend un bouclier 1 dont la face extérieure ou peau 2 est munie d'ouvertures 3 et 4 prévues pour recevoir respectivement des feux anti-brouillard et une grille de prise d'air. The bumper of FIG. 1 comprises a shield 1, the outer face or skin 2 of which is provided with openings 3 and 4 provided for receiving respectively fog lights and an air intake grille.
Conformément à l'invention, le bouclier comporte une ouverture longitudinale 5 qui s'étend sensiblement sur toute la largeur du véhicule. According to the invention, the shield has a longitudinal opening 5 which extends substantially over the entire width of the vehicle.
Sur les vues en coupe des figures 5 à 8, on voit qu'au niveau de l'ouverture 5, la paroi du bouclier se prolonge vers l'intérieur du pare-chocs sous la forme d'une poutre 6 à section en U. In the sectional views of FIGS. 5 to 8, it can be seen that at the opening 5, the wall of the shield extends towards the inside of the bumper in the form of a beam 6 with a U-section.
En d'autres termes, les parois du bouclier et de la poutre se raccordent de façon continue le long des bords 7 de l'ouverture 5. In other words, the walls of the shield and of the beam are connected continuously along the edges 7 of the opening 5.
De cette manière, on comprend que le fait de réaliser la poutre d'un seul tenant avec le bouclier n'entralne l'apparition d'aucune retassure sur la peau du bouclier. In this way, it is understood that the fact of making the beam in one piece with the shield does not center the appearance of any shrinkage on the skin of the shield.
On comprend également que, la poutre étant intimement liée au bouclier, elle constitue avec ce dernier un ensemble de grande inertie. It is also understood that, the beam being intimately linked to the shield, it constitutes with the latter a set of great inertia.
Un plastron 8, réalisé indépendamment du bouclier, est rapporté sur la peau 2 pour venir obturer l'ouverture 5. A faceplate 8, produced independently of the shield, is attached to the skin 2 to close off the opening 5.
Ce plastron peut être clippé, collé ou soudé au niveau des bords 7 de l'ouverture. This plastron can be clipped, glued or welded at the edges 7 of the opening.
Dans le mode de réalisation de la figure 1, la poutre comporte intérieurement des cloisons longitudinales et/ou transversales 9 qui occupent toute la section de la poutre et viennent à effleurement de l'ouverture 5. In the embodiment of FIG. 1, the beam internally comprises longitudinal and / or transverse partitions 9 which occupy the entire section of the beam and come into contact with the opening 5.
Ces cloisons 9 provoquent inévitablement l'apparition de retassures sur la paroi extérieure de la poutre 6 mais on comprend que ces retassures, non visibles depuis l'extérieur, ne dégradent aucunement l'esthétique du bouclier. These partitions 9 inevitably cause the appearance of recesses on the outer wall of the beam 6 but it is understood that these recesses, not visible from the outside, do not in any way degrade the aesthetics of the shield.
Avantageusement, les cloisons 9 sont plus rapprochées les unes des autres au droit des longerons du véhicule, ce qui permet de renforcer la résistance de la poutre au niveau de ses points d'appui que sont les longerons du véhicule. Advantageously, the partitions 9 are closer to each other in line with the side members of the vehicle, which makes it possible to strengthen the resistance of the beam at its support points which are the side members of the vehicle.
Sur la figure 2, on a représenté le pare-chocs à sa sortie du moule. In Figure 2, there is shown the bumper at its exit from the mold.
Du fait que le pare-chocs selon l'invention présente une structure relativement simple qui peut être définie par un moule dont la cavité se prête facilement au fluage d'une matière thermoplastique fondue, on peut réaliser l'injection de la matière thermoplastique par le centre de la pièce et en limitant le nombre de points d'injection tout en utilisant un moule économique car il ne nécessite pas d'être équipé d'organes de chauffage destinés à empêcher le durcissement prématuré de la matière thermoplastique injectée. Because the bumper according to the invention has a relatively simple structure which can be defined by a mold whose cavity easily lends itself to the creep of a molten thermoplastic material, it is possible to inject the thermoplastic material by the center of the part and by limiting the number of injection points while using an economical mold because it does not require to be equipped with heating members intended to prevent the premature hardening of the injected thermoplastic material.
On voit sur la figure 2, trois carottes 10 qui correspondent aux canaux d'injection de matière thermoplastique prévus dans le moule. We see in Figure 2, three cores 10 which correspond to the thermoplastic material injection channels provided in the mold.
Une telle injection simplifiée permet d'améliorer le remplissage de la cavite du moule ainsi que l'aspect du pare-chocs obtenu. Such a simplified injection improves the filling of the mold cavity as well as the appearance of the bumper obtained.
La poutre 6 peut être renforcée en utilisant différentes techniques dont celles illustrées aux figures 6, 7 et 8. The beam 6 can be reinforced using different techniques including those illustrated in Figures 6, 7 and 8.
A la figure 6, la paroi de la poutre 6 est double, ce qui est obtenu par injection complémentaire de gaz dans la partie du moule correspondant à la poutre. On provoque ainsi la formation d'une chambre gazeuse 6a entre les deux parties de paroi de la poutre, d'où une meilleure rigidité de celle-ci moyennant une relativement faible augmentation de son poids. In FIG. 6, the wall of the beam 6 is double, which is obtained by additional injection of gas into the part of the mold corresponding to the beam. This causes the formation of a gas chamber 6a between the two wall parts of the beam, hence better rigidity thereof with a relatively small increase in its weight.
On peut également utiliser un moule permettant d'injecter simultanément le bouclier et la poutre en deux matières thermoplastiques différentes mais compatibles entre elles c'est-à-dire aptes à se souder l'une à l'autre lorsqu'elles se rejoignent à l'état fondu dans le moule. One can also use a mold making it possible to simultaneously inject the shield and the beam in two different thermoplastic materials which are compatible with each other, that is to say capable of being welded to each other when they join at the melted in the mold.
A titre d'exemple, on peut utiliser un polypropylène pour réaliser le bouclier et un ensemble de deux couches, également désigné sous le terme de bicouche, de polypropylène et de polypropylène chargé de fibres de verre pour réaliser la poutre. For example, one can use a polypropylene to make the shield and a set of two layers, also referred to as a bilayer, polypropylene and polypropylene loaded with glass fibers to make the beam.
Dans le mode de réalisation de la figure 7, on a rempli la poutre 6 avec une mousse 6b qui remplit les espaces laissés libres entre les cloisons transversales et longitudinales 9. In the embodiment of FIG. 7, the beam 6 has been filled with a foam 6b which fills the spaces left free between the transverse and longitudinal partitions 9.
Dans le mode de réalisation de la figure 8, la poutre comporte une feuille de renfort 6c qui est un tissé de fibres de verre et de fibres de matière thermoplastique. In the embodiment of Figure 8, the beam comprises a reinforcing sheet 6c which is a woven of glass fibers and fibers of thermoplastic material.
Sur les figures 3 et 4, on a représenté un autre mode de réalisation de pare-chocs selon l'invention. Figures 3 and 4 show another embodiment of the bumper according to the invention.
Ce pare-chocs il comporte un bouclier dont la peau 2 se présente extérieurement comme celle du pare-chocs précédemment décrit. This bumper includes a shield, the skin 2 of which presents itself externally like that of the bumper described above.
Dans ce mode de réalisation, la poutre 12 comporte un nervurage densifié 13 sur sa face opposée au bouclier et au voisinage des longerons (non représentés) du véhicule sur lesquels elle doit prendre appui en cas de choc. In this embodiment, the beam 12 has a densified ribbing 13 on its face opposite the shield and in the vicinity of the side members (not shown) of the vehicle on which it must bear in the event of an impact.
Dans une variante de ce mode de réalisation, le nervurage densifié 13 pourrait être remplacé par une boîte de confinement dans laquelle on viendrait loger un absorbeur de chocs tel qu'une structure en nid d'abeilles. In a variant of this embodiment, the densified ribbing 13 could be replaced by a containment box in which one would house a shock absorber such as a honeycomb structure.
Il est bien entendu que les modes de réalisation qui viennent d'être décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toute modification désirable sans sortir pour cela du cadre de l'invention. It is understood that the embodiments which have just been described have no limiting character and that they can receive any desirable modification without departing from the scope of the invention.
