Description

"Dispositif d'assemblage impliquant une glace de projecteur fixée à une pièce de véhicule automobile, procédés de fabrication". "Assembly device involving a headlamp attached to a part of a motor vehicle, manufacturing processes".

L'invention concerne principalement un dispositif d'assemblage impliquant une glace de projecteur fixée à une pièce montée sur un véhicule automobile. Les glaces de projecteur protégeant les feux et les dispositifs de signalisation sont généralement rapportés sur les peaux de pare chocs avant et arrière des véhicules automobile et solidarisés à ces pare chocs au moyen de systèmes de fixation qui engendrent un jeu inesthétique entre les pièces en question. Par exemple, dans la publication FR 2 695 360, la glace est montée sur le projecteur, lui-même fixé au pare choc par un système d'encliquetage. Les moyens de fixation sont complexes et un espace est présent entre le bord de la glace et le bord du logement de réception de la glace fait dans le pare choc. The invention mainly relates to an assembly device involving a projector lens attached to a part mounted on a motor vehicle. The headlamps protecting the lights and the signaling devices are generally reported on the front and rear bumper skins of motor vehicles and secured to these bumpers by means of fastening systems which generate an unsightly game between the parts in question. For example, in the publication FR 2 695 360, the glass is mounted on the projector, itself fixed to the bumper by a latching system. The fixing means are complex and a space is present between the edge of the ice and the edge of the receiving housing of the ice made in the bumper.

Par ailleurs, lorsque la glace de projecteur est directement rapportée sur le pare choc, cette glace fait généralement saillie depuis le pare choc, cette configuration rendant également l'assemblage entre ces pièces inesthétique. Furthermore, when the projector glass is directly attached to the bumper, the ice usually protrudes from the bumper, this configuration also making the assembly between these parts unsightly.

L'invention a pour objectif de pallier les inconvénients précités. A cet effet, l'invention concerne un dispositif d'assemblage d'une glace de projecteur sur une pièce de véhicule automobile et qui est essentiellement caractérisé en ce que la tranche de la glace est au moins en partie en appui de contact contre le bord périphérique d'un logement de réception de la dite glace réalisé dans la dite pièce. Avantageusement, la face externe de la glace de 35 projecteur et la face externe de la pièce sont en continuité l'une de l'autre. The invention aims to overcome the aforementioned drawbacks. To this end, the invention relates to a device for assembling a projector lens on a motor vehicle part and which is essentially characterized in that the edge of the mirror is at least partly in contact support against the edge peripheral of a receiving housing of said ice made in said room. Advantageously, the outer face of the projector glass and the outer face of the part are in continuity with one another.

Selon un aspect avantageux de l'invention, la glace de projecteur est directement surmoulée dans la pièce. En variante, la glace de projecteur peut être moulée dans un modèle réalisé à partir du moule de la pièce puis rapportée sur cette pièce. De préférence, la surface de contact entre la tranche de la glace de projecteur et le bord périphérique du logement de réception de la glace fait dans la pièce, est supérieure à la surface annulaire plane définie par la plus petit épaisseur entre l'épaisseur de la glace de projecteur et l'épaisseur de la peau de pare choc au niveau de leur surface de contact. Cette surface de contact peut présenter un profil en forme de S, ou en image miroir de S, ou en Z ou en image 15 miroir de Z. Lorsque la glace est obtenue par moulage dans un modèle réalisé à partir du moule de la pièce puis rapportée sur cette pièce, la glace de projecteur peut être fixée à la pièce au moyen d'un cordon de matière 20 adhésive disposé sur la surface de contact entre la tranche de la glace de projecteur et le bord périphérique du logement de réception de la glace fait dans la pièce. On peut en outre prévoir que la pièce est un pare-choc ou une peau de pare choc. 25 L'invention concerne également un procédé de fabrication du dispositif d'assemblage précédemment décrit qui comprend au moins les étapes suivantes : moulage de la pièce, surmoulage de la glace de projecteur dans la pièce, 30 et fixation concomitante ou ultérieure de la glace de projecteur sur la pièce En variante, le procédé de fabrication du dispositif d'assemblage peut comprendre au moins les étapes 35 suivantes . - moulage de la pièce, - moulage de la glace de projecteur dans un modèle réalisé à partir du même moule que la pièce, et - fixation de la glace de projecteur sur la pièce. L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant deux modes de réalisation de l'invention et dans lesquels : la figure 1 est une vue de face d'une zone d'extrémité d'un pare choc avant de véhicule automobile intégrant le dispositif d'assemblage de l'invention ; la figure 2 est une vue de coté de la zone d'extrémité du pare choc de la figure 1 ; la figure 3 est une vue en coupe du dispositif d'assemblage de l'invention selon la ligne III-III de la figure 1 ; la figure 4 est une vue agrandie de la partie 20 cerclée IV de la figure 3 selon un premier mode de réalisation de l'invention ; la figure 5 est une vue identique à celle de la figure 4 illustrant une variante du premier mode de réalisation ; 25 la figure 6 est une vue identique à celle de la figure 4 illustrant un deuxième mode de réalisation de l'invention ; et la figure 7 est une vue en perspective depuis l'arrière de la zone d'extrémité du pare choc représenté 30 sur la figure 1. On se réfère en premier lieu aux figures 1 et 2. Une glace de projecteur 1 rouge ou cristal en polyméthacrylate de méthyle derrière laquelle est monté un projecteur de feu ou de signalisation par exemple, est 35 fixée sur la peau de pare choc d'un véhicule automobile 2 en polypropylène. According to an advantageous aspect of the invention, the projector lens is directly overmolded in the part. Alternatively, the projector glass can be molded into a model made from the mold of the piece and then attached to this piece. Preferably, the contact area between the edge of the headlamp ice and the peripheral edge of the ice receiving housing in the workpiece is greater than the planar annular surface defined by the smaller thickness between the thickness of the projector glass and the thickness of the bumper skin at their contact surface. This contact surface may have an S-shaped profile, or a mirror image of S, or a Z-shape or a mirror image of Z. When the ice is obtained by molding in a model made from the mold of the part, then attached to this piece, the projector glass can be attached to the workpiece by means of a bead of adhesive material disposed on the contact surface between the wafer of the projector glass and the peripheral edge of the ice-receiving housing. done in the room. It can further be provided that the piece is a bumper or a bumper skin. The invention also relates to a method of manufacturing the assembly device described above which comprises at least the following steps: molding of the workpiece, over-molding of the projector glass in the workpiece, and concomitant or subsequent fixing of the ice-cream As a variant, the manufacturing method of the assembly device may comprise at least the following steps. - molding of the room, - casting of the projector glass in a model made from the same mold as the room, and - fixing the projector glass on the room. The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the following explanatory description made with reference to the accompanying schematic drawings given solely by way of example illustrating two Embodiments of the invention and in which: Figure 1 is a front view of an end zone of a front bumper of a motor vehicle incorporating the assembly device of the invention; Figure 2 is a side view of the end zone of the bumper of Figure 1; Figure 3 is a sectional view of the assembly device of the invention along the line III-III of Figure 1; Figure 4 is an enlarged view of the circled portion IV of Figure 3 according to a first embodiment of the invention; Figure 5 is a view identical to that of Figure 4 illustrating a variant of the first embodiment; Figure 6 is a view identical to that of Figure 4 illustrating a second embodiment of the invention; and Fig. 7 is a perspective view from the rear of the end portion of the bumper shown in Fig. 1. Referring first to Figs. 1 and 2. polymethylmethacrylate behind which is mounted a fire or signaling projector for example, is attached to the bumper skin of a motor vehicle 2 polypropylene.

Pour ce faire, un logement de réception 3 de la glace de projecteur 1 est prévue dans l'épaisseur de la peau du pare choc 2. Comme visible sur les figures 3 et 4, la tranche 7 de la glace de projecteur 1 est en appui de contact contre le bord périphérique 6 du logement de réception de la glace 3 fait dans la peau de pare choc 2. La surface de contact 8 entre la glace de projecteur 1 et la peau de pare choc 2 est en coupe en forme d'image miroir d'un Z. La tranche 7 de la glace 1 est de forme conjuguée au bord périphérique 6 du logement 3 fait dans la peau de pare choc 2 et les épaisseurs respectives El et E2 de la glace 1 et de la peau de pare choc 2 sont égales. To do this, a receiving housing 3 of the projector window 1 is provided in the thickness of the skin of the bumper 2. As can be seen in FIGS. 3 and 4, the edge 7 of the projector window 1 is in abutment. contacting against the peripheral edge 6 of the ice receiving housing 3 made in the bumper skin 2. The contact surface 8 between the projector lens 1 and the bumper skin 2 is in cross section in the form of an image mirror Z. The slice 7 of the ice 1 is of conjugated shape to the peripheral edge 6 of the housing 3 made in the bumper skin 2 and the respective thicknesses E1 and E2 of the ice 1 and the bumper skin 2 are equal.

Par ailleurs, la forme en image miroir d'un Z est telle que les faces externes respectives 4 et 5 de la glace 1 et de la peau de pare choc 2 sont en affleurement. Une telle configuration est obtenue par surmoulage de la glace 1 dans la peau de pare choc 2 ce qui confère un assemblage entre la glace 2 et le pare choc 2 ne laissant apparaître aucun jeu entre la tranche 7 et le bord périphérique 6. Préalablement au surmoulage de la glace, la peau de pare choc 2 aura été moulée dans un moule approprié. Par ailleurs, cette réalisation par surmoulage, permet également d'obtenir un affleurement parfait des faces externes respectives 4 et 5 de la glace 1 et de la peau de pare choc 2. Furthermore, the mirror image form of a Z is such that the respective outer faces 4 and 5 of the ice 1 and the bumper skin 2 are flush. Such a configuration is obtained by overmolding the ice 1 in the bumper skin 2 which confers an assembly between the ice 2 and the bumper 2 leaving no gap between the edge 7 and the peripheral edge 6. Prior to overmolding of the ice, the bumper skin 2 has been molded into a suitable mold. Moreover, this embodiment by overmolding also makes it possible to obtain a perfect outcrop of the respective external faces 4 and 5 of the ice 1 and the bumper skin 2.

Lorsque les matériaux constitutifs de la peau de pare choc 2 d'une part et de la glace de projecteur 1 d'autre part ne permettent pas d'assurer l'adhésion de la glace sur la pare choc, on prévoit d'autres moyens de fixation, par exemple par vissage de la glace 1 sur la peau de pare choc 2 depuis l'arrière du pare choc, ces moyens n'étant pas représentés sur les figures. When the materials constituting the bumper skin 2 on the one hand and the projector glass 1 on the other hand do not ensure the adhesion of the ice on the bumper, other means of fixing, for example by screwing the lens 1 on the bumper skin 2 from the rear of the bumper, these means not being shown in the figures.

On peut également prévoir, pour une surface de contact 8 de même forme que celle de la figure 2, que la fabrication de cet assemblage soit obtenu par moulage de la glace 1 dans un modèle obtenu à partir du même moule que le pare choc 2, puis que cette glace 1 soit rapportée sur le pare choc 2 qui a été préalablement moulé. Dans ce cas, comme visible sur la figure 5, pour assurer la fixation de la glace 1 sur le pare choc 2, on peut prévoir la mise en place d'un cordon de colle 10 le long de la surface de contact 8 entre la glace 1 et le pare choc 2. Selon un deuxième mode de réalisation représenté sur la figure 6, la surface de contact 8' entre la glace de projecteur 1' et le pare choc 2' est en coupe en forme de S et l'épaisseur El' de la glace 1' est inférieure à l'épaisseur E2' de la peau de pare choc 2'. Par ailleurs, la forme en S de la surface de contact 8 est telle que les faces externes respectives 4' et 5' de la glace 1 et du pare choc 2' sont en affleurement. It can also be provided, for a contact surface 8 of the same shape as that of FIG. 2, that the manufacture of this assembly is obtained by molding the ice 1 in a model obtained from the same mold as the bumper 2. then that this ice 1 is reported on the bumper 2 which was previously molded. In this case, as shown in Figure 5, to ensure the attachment of the ice 1 on the bumper 2, we can provide the establishment of a bead of adhesive 10 along the contact surface 8 between the ice 1 and the bumper 2. According to a second embodiment shown in FIG. 6, the contact surface 8 'between the projector lens 1' and the bumper 2 'is in S-shaped section and the thickness E 1 'ice is less than the thickness E2' of the bumper skin 2 '. Furthermore, the S shape of the contact surface 8 is such that the respective outer faces 4 'and 5' of the glass 1 and the bumper 2 'are flush.

En référence à la figure 7, un boitier renfermant le réflecteur, la lampe du porte lampe ou de la douille 12 est rapporté et fixé à la glace 1 du coté de sa face interne non visible. Ce boîtier 12 est fixé à la glace par des moyens de 25 fixation connus, par exemple par vissage ou par encliquetage. Par ailleurs, un joint d'étanchéité 13 disposé le long de l'arête d'intersection 14 entre le boîtier 12 et la face interne de la glace 1 peut être prévu pour rendre 30 étanche ce boîtier 12, et protéger les pièces qu'il contient. Bien entendu, l'invention peut s'appliquer à une glace montée sur toute pièce d'un véhicule automobile. Selon les modes de réalisation décrits précédemment, 35 l'absence de jeu entre la tranche 7 de la glace 1 et le bord périphérique 6 du logement de glace 3 dans la peau de pare choc, ainsi que l'affleurement des faces externes respectives 4,5 de la glace 1 et de la peau de pare choc 2 sont obtenus par la réalisation de la glace 1 et de la peau de pare choc 2 à partir d'un même moule. Soit par surmoulage de la glace 1 dans la peau de pare choc 2, soit par moulage de la glace 1 dans une pièce réalisée à partir du moule du pare choc 2. Et plus particulièrement, la coïncidence parfaite de forme de la tranche de la glace 7 et du bord périphérique 6 du logement de réception de la glace 3 et l'affleurement précis des faces externes 4,5 de ces deux pièces est spécifique de la fabrication de la glace et de la peau de pare choc à partir du même moule. Mais on peut envisager tout autre procédé de fabrication, par exemple l'usinage, qui permettrait d'obtenir une coïncidence entre les pièces qui serait suffisante pour limiter le jeu entre les deux pièces tout en respectant leur affleurement. Par ailleurs, la surface de contact 8 entre la tranche 7 de la glace 1 et le bord interne 6 du logement 3 peut se présenter sous différentes formes et les épaisseurs respectives El et E2 de la tranche de la glace 7 et du bord périphérique 6 au niveau de la surface de contact 8 peuvent également varier. Referring to Figure 7, a housing enclosing the reflector, lamp lamp holder or sleeve 12 is attached and attached to the ice 1 on the side of its inner face not visible. This housing 12 is fixed to the ice by known fastening means, for example by screwing or snapping. Furthermore, a seal 13 disposed along the intersection edge 14 between the housing 12 and the inner face of the glass 1 may be provided to seal the housing 12, and protect the parts it contains. Of course, the invention can be applied to an ice-cream mounted on any part of a motor vehicle. According to the embodiments described above, the absence of clearance between the slice 7 of the ice 1 and the peripheral edge 6 of the ice housing 3 in the bumper skin, as well as the outcropping of the respective outer faces 4, 5 of the ice 1 and the bumper skin 2 are obtained by producing the ice 1 and the bumper skin 2 from the same mold. Or by overmoulding of the ice 1 in the bumper skin 2, or by molding the ice 1 in a part made from the mold of the bumper 2. And more particularly, the perfect coincidence of shape of the edge of the ice 7 and the peripheral edge 6 of the receiving housing of the ice 3 and the precise outcropping of the external faces 4,5 of these two parts is specific to the manufacture of ice and bumper skin from the same mold. But we can consider any other manufacturing process, for example machining, which would obtain a coincidence between parts that would be sufficient to limit the play between the two parts while respecting their outcropping. Furthermore, the contact surface 8 between the slice 7 of the glass 1 and the inner edge 6 of the housing 3 can be in various forms and the respective thicknesses E1 and E2 of the edge of the ice 7 and the peripheral edge 6 to level of the contact surface 8 may also vary.
