Description

OUVRANT DE VEHICULE AUTOMOBILE COMPRENANT UN RAIDISSEUR ET VEHICULE MUNI UN TEL OUVRANT. OPENING OF A MOTOR VEHICLE COMPRISING A STIFFENER AND VEHICLE PROVIDED WITH SUCH AN OPENING.
L' invention concerne principalement un ouvrant de véhicule automobile pourvu d'une vitre et comprenant un raidisseur destiné à rigidifier au moins une zone de 1' ouvrant .The invention relates mainly to an opening of a motor vehicle provided with a window and comprising a stiffener for stiffening at least one area of one opening.
L' invention concerne également un véhicule notamment automobile muni d'un tel ouvrant. Les ouvrants de véhicule automobile et notamment les portières latérales doivent présenter une certaine rigidité afin notamment de protéger les passagers lors d'un choc et de donner visuellement une impression de robustesse au client. Les figures 1 à 5 présentent 2 types de raidisseurs connus montés sur un panneau de portière.The invention also relates to a vehicle including automobile equipped with such an opening. The opening of a motor vehicle and in particular the side doors must have a certain rigidity in particular to protect the passengers during a shock and visually give an impression of robustness to the customer. Figures 1 to 5 show two types of known stiffeners mounted on a door panel.
Plus précisément, les figures 1 et 2 présentent un raidisseur horizontal respectivement illustré en perspective depuis la face externe du panneau de la portière et en coupe selon la ligne II-II de la figure 1, et les figures 3 à 5 illustrent un raidisseur vertical assemblé sur un raidisseur horizontal respectivement illustré en perspective depuis la face externe du panneau de la portière, en coupe selon la ligne IV-IV de la figure 3 et en perspective pour sa partie supérieure depuis la face interne du panneau.More specifically, Figures 1 and 2 show a horizontal stiffener respectively illustrated in perspective from the outer face of the door panel and in section along line II-II of Figure 1, and Figures 3 to 5 illustrate an assembled vertical stiffener on a horizontal stiffener respectively illustrated in perspective from the outer face of the door panel, in section along the line IV-IV of Figure 3 and in perspective for its upper part from the inner face of the panel.
Sur les figures 1 et 2, le raidisseur horizontal 1 est un profilé 1 qui s'étend longitudinalement sur la face interne 9 du panneau de portière 3 le long de la zone lécheur 2, cette zone correspondant au bord 4 du panneau de portière 3 situé à proximité de la partie inférieure 5 de la vitre 6.In Figures 1 and 2, the horizontal stiffener 1 is a profile 1 which extends longitudinally on the inner face 9 of the door panel 3 along the liner zone 2, this zone corresponding to the edge 4 of the door panel 3 located near the lower part 5 of the window 6.
En coupe, ce raidisseur 1 présente une paroi supérieure 8 qui est solidarisée à la zone lécheur 2 de la portière 3 par des points de soudure électrique 7 et qui se prolonge vers le bas par une paroi inférieure 11 formant un angle obtu avec la paroi supérieure 8 et dont l'extrémité libre 12 est calée contre la face interne 9 du panneau de portière 3 au moyen d'une bande de mastic 13.In section, this stiffener 1 has an upper wall 8 which is secured to the liner zone 2 of the door 3 by electric welding points 7 and which is extended downwards by a lower wall 11 forming an obtuse angle with the upper wall 8 and whose free end 12 is wedged against the inner face 9 of the door panel 3 by means of a mastic strip 13.
Mais un tel raidisseur 1 permet de rigidifier la zone lécheur 2 de la portière 3, il ne permet de rigidifier que cette zone et ne participe pas à la rigidité du panneau 3. Par ailleurs, sa masse est relativement importante puisqu'elle peut atteindre 700 grammes.But such a stiffener 1 makes it possible to stiffen the licking zone 2 of the door 3, it only makes it possible to stiffen this area and does not participate in the rigidity of the panel 3. Moreover, its mass is relatively large since it can reach 700 grams.
Sur les figures 3 à 5, un raidisseur vertical 15 est monté le long de la face interne 9 du panneau 3 depuis un embouti 22 destiné à recevoir un protecteur flan non représenté jusqu'à un raidisseur horizontal 16 semblable au raidisseur 1 des figures 1 et 2 excepté en ce que sa paroi supérieure 17 est pliée et solidarisée à la zone lécheur 2 de la portière 3 par sertissage définissant une zone de sertissage 23. Le raidisseur vertical 15 présente la forme d'une paroi 18 comportant deux nervures 25 (figure 5) et dont l'extrémité supérieure 19 est légèrement pliée et solidarisée à la partie inférieure de la face interne 21 du raidisseur horizontal 16 par des points de soudure électrique 24. La partie inférieure de la face externe du raidisseur horizontal 16 est elle calée contre la face interne 9 du panneau de portière 3 au moyen d'une bande de mastic 20.In FIGS. 3 to 5, a vertical stiffener 15 is mounted along the internal face 9 of the panel 3 from a stamping 22 intended to receive a not shown blank protector up to a horizontal stiffener 16 similar to the stiffener 1 of FIGS. 2 except that its upper wall 17 is folded and secured to the liner zone 2 of the door 3 by crimping defining a crimping zone 23. The vertical stiffener 15 has the shape of a wall 18 having two ribs 25 (FIG. ) and whose upper end 19 is slightly bent and secured to the lower part of the inner face 21 of the horizontal stiffener 16 by electric welding points 24. The lower part of the outer face of the horizontal stiffener 16 is wedged against the internal face 9 of the door panel 3 by means of a mastic strip 20.
De la même façon, l'extrémité inférieure 26 du raidisseur vertical 15 est solidarisée à la face interne 9 du panneau 3 au niveau de l'embouti de réception du protecteur flan 22 par des points de soudure électrique 27.In the same way, the lower end 26 of the vertical stiffener 15 is secured to the inner face 9 of the panel 3 at the receiving end of the blank protector 22 by electric welding points 27.
Néanmoins, l'amélioration de la rigidité sur le panneau, comme notamment illustrée par le raidisseur vertical couplé au raidisseur horizontal des figures 3 à 5, implique l'utilisation de pièces supplémentaires qui entraînent une augmentation du poids du véhicule.Nevertheless, the improvement of the rigidity on the panel, as illustrated in particular by the stiffener vertical coupled to the horizontal stiffener of Figures 3 to 5, involves the use of additional parts that lead to an increase in the weight of the vehicle.
Or, l'optimisation de la masse est un souci permanent lors de la conception des ouvrants.However, optimization of the mass is a permanent concern when designing the opening.
Par ailleurs, il est nécessaire d'assembler le raidisseur vertical 15 au raidisseur horizontal 16 ce qui augmente les coûts d'assemblage.Furthermore, it is necessary to assemble the vertical stiffener 15 to the horizontal stiffener 16 which increases the assembly costs.
L'objectif de l'invention est donc de mettre au point un raidisseur permettant d'obtenir une rigidité efficace le long de la portière pour une masse et un coût d'assemblage minimes.The object of the invention is therefore to develop a stiffener to obtain effective rigidity along the door for a minimum mass and assembly cost.
A cet effet, l'invention propose un ouvrant de véhicule automobile pourvu d'une vitre et comprenant un raidisseur destiné à rigidifier au moins une zone dudit ouvrant qui est essentiellement caractérisé en ce que ledit raidisseur s'étend verticalement le long de la face interne du panneau de l'ouvrant depuis la zone lécheur proche de la vitre. De préférence, la largeur de partie supérieure du raidisseur prise au niveau de la zone lécheur permet d'assurer la rigidification de cette zone.For this purpose, the invention proposes an opening of a motor vehicle provided with a window and comprising a stiffener for stiffening at least one zone of said opening which is essentially characterized in that said stiffener extends vertically along the inner face the opening panel from the lick area near the window. Preferably, the width of the upper portion of the stiffener taken at the level of the licking zone makes it possible to stiffen this zone.
Avantageusement, le raidisseur comporte au moins une nervure de renfort. En outre, le raidisseur peut présenter au moins une zone de calage en appui contre la face interne du panneau .Advantageously, the stiffener comprises at least one reinforcing rib. In addition, the stiffener may have at least one wedging zone bearing against the inner face of the panel.
On peut également prévoir que le raidisseur s'étende jusqu'à un raidisseur central. Avantageusement, le raidisseur de l'ouvrant de l'invention présente une forme général de Y de façon à comprendre deux branches latérales en partie supérieure et une jambe en partie inférieure, les extrémités libres respectives des deux branches latérales étant reliées entre elles par une branche transversale solidairement fixée à la face interne de la zone lécheur.It is also possible that the stiffener extends to a central stiffener. Advantageously, the stiffener of the opening of the invention has a general shape of Y so as to comprise two lateral branches in the upper part and a leg in the lower part, the respective free ends of the two lateral branches being connected. between them by a transverse branch integrally attached to the inner face of the licking zone.
De façon préférentielle, les deux branches latérales du raidisseur comportent chacune une nervure de renfort, ces deux nervures se prolongeant par deux nervures parallèles appartenant à la jambe du raidisseur.Preferably, the two lateral branches of the stiffener each comprise a reinforcing rib, these two ribs being extended by two parallel ribs belonging to the leg of the stiffener.
Par ailleurs, la branche transversale supérieure présente une largeur d'environ 150 millimètres et la jambe présente une largeur comprise entre 30 et 50 millimètres.In addition, the upper transverse branch has a width of about 150 millimeters and the leg has a width of between 30 and 50 millimeters.
Selon un aspect avantageux de l'invention, le raidisseur comporte deux zones centrales de calage au niveau de chacune des deux branches, par lesquelles il est calé contre la face interne du panneau de porte au moyen d'une bande de mastic respective.According to an advantageous aspect of the invention, the stiffener comprises two central zones of wedging at each of the two branches, by which it is wedged against the internal face of the door panel by means of a respective strip of mastic.
De préférence, l'extrémité inférieure de la jambe du raidisseur est calée au moyen de bandes de mastic entre la face interne du panneau et un logement de réception fait dans un raidisseur latéral horizontal. On peut prévoir par ailleurs que le raidisseur soit solidarisé au panneau de l'ouvrant par sa partie supérieure située contre la zone lécheur par des points de soudure électrique.Preferably, the lower end of the stiffener leg is keyed by means of strips of sealant between the inner face of the panel and a receiving housing made in a horizontal lateral stiffener. It can also be provided that the stiffener is secured to the panel of the opening by its upper part located against the liner area by electric welding points.
Enfin, l'invention concerne également un véhicule automobile pourvu d'un ouvrant décrit précédemment.Finally, the invention also relates to a motor vehicle provided with an opening described above.
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 en perspective de la portière depuis sa face externe sur laquelle est monté un raidisseur horizontal de l'art antérieur ; la figure 2 est une vue en coupe selon la ligne II-II de la figure 1 ; la figure 3 est une vue en perspective de la portière depuis sa face externe sur laquelle est monté un raidisseur vertical couplé à un raidisseur horizontal selon l'art antérieur ; la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 3 ; la figure 5 est une vue en perspective partielle de la partie supérieure du raidisseur vertical des figures 3 et 4 depuis la face interne de la portière; la figure 6 est une vue en perspective depuis la face interne du panneau de portière du raidisseur de l'invention selon une première variante ; - la figure 7 est une vue en coupe selon la ligne VII-VII de la figure 6 ; et la figure 8 est une vue en perspective partielle de la partie supérieure d'un raidisseur de l'invention depuis la face interne du panneau de portière selon une seconde variante.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 perspective view of the door from its outer face on which is mounted a horizontal stiffener of the prior art; Figure 2 is a sectional view along the line II-II of Figure 1; Figure 3 is a perspective view of the door from its outer face on which is mounted a vertical stiffener coupled to a horizontal stiffener according to the prior art; Figure 4 is a sectional view along the line IV-IV of Figure 3; Figure 5 is a partial perspective view of the upper portion of the vertical stiffener of Figures 3 and 4 from the inner face of the door; Figure 6 is a perspective view from the inner face of the door panel of the stiffener of the invention according to a first variant; - Figure 7 is a sectional view along the line VII-VII of Figure 6; and Figure 8 is a partial perspective view of the upper part of a stiffener of the invention from the inner face of the door panel according to a second variant.
En référence aux figures 6 à 8, le raidisseur de l'invention 29 ou 30 est réalisé en une seule pièce et s'étend le long de la face interne 9 du panneau 3 depuis la zone lécheur 2 à proximité de la vitre, non représentée, jusqu'à une zone située sensiblement à mi- hauteur de la portière.Referring to Figures 6 to 8, the stiffener of the invention 29 or 30 is made in one piece and extends along the inner face 9 of the panel 3 from the liner zone 2 near the window, not shown to an area approximately halfway up the door.
Ce raidisseur 29 ou 30 présente une forme général en Y comprenant deux branches 34,35 et une jambe 42.This stiffener 29 or 30 has a general Y shape comprising two branches 34, 35 and one leg 42.
Nous allons maintenant décrire plus particulièrement le raidisseur représenté aux figures 6 et 7.We will now describe more particularly the stiffener shown in Figures 6 and 7.
Les extrémités libres respectives 32,33 des deux branches 34 et 35 sont reliées entre elles par une branche transversale 36 faite sous forme d'une plaque solidarisée à la face interne 37 du panneau 3 au niveau d'une partie non sertie de la zone lécheur 2 par des points de soudure électrique 38, ou en variante, par laser .The respective free ends 32,33 of the two branches 34 and 35 are interconnected by a transverse branch 36 made in the form of a plate secured to the inner face 37 of the panel 3 at a non-crimped portion of the liner zone 2 by electric welding spots 38, or alternatively, by laser.
De part et d'autre de cette branche transversale 36, le bord supérieur 40 du panneau 3 est replié vers la face interne 9 de ce panneau 3 en formant un sertissage, de façon à permettre l'accrochage d'un joint permettant d' étanchéifier la zone présente entre l'extrémité du panneau 3 et la vitre.On either side of this transverse branch 36, the upper edge 40 of the panel 3 is folded towards the inner face 9 of this panel 3 forming a crimping, so as to allow the attachment of a seal to seal the area between the end of the panel 3 and the window.
Dans le prolongement de cette branche transversale 36, le raidisseur présente un décroché 41a dirigé vers la face interne 9 du panneauIn the extension of this transverse branch 36, the stiffener has a drop 41a directed towards the inner face 9 of the panel
Le raidisseur de la figure 6 présente en outre un élément de rigidification 54 de forme générale en Y et en saillie par rapport à la face interne 9 du panneau 3 de façon à former sur chaque branche 34,35 une rainure respectivement 43, 44 et, au niveau de la jambe 42, deux rainures parallèles 45,46 qui sont jointes à leurs extrémités inférieures respectives 47,48 par une rainure transversale 49. Les extrémités supérieures des rainures respectives 43,44 des deux branches 34,35 du raidisseur 30 de cette même figure 6 sont reliées entre elles par une rainure transversale 50 qui s'étend en largeur depuis le décroché 41a et qui présente trois trous oblongs 52, destinés à alléger le raidisseur, disposés longitudinalement le long du bord supérieur 53 de la rainure transversale 50.The stiffener of FIG. 6 furthermore has a stiffening element 54 of generally Y-shape and projecting from the inside face 9 of the panel 3 so as to form on each branch 34, 35 a groove respectively 43, 44 and, at the leg 42, two parallel grooves 45,46 which are joined at their respective lower ends 47,48 by a transverse groove 49. The upper ends of the respective grooves 43,44 of the two legs 34,35 of the stiffener 30 of this FIG. 6 is connected to each other by a transverse groove 50 which extends in width from the stall 41a and which has three oblong holes 52 intended to lighten the stiffener, arranged longitudinally along the upper edge 53 of the transverse groove 50.
En référence aux figures 6 et 7, la face avant 61 de la partie inférieure 55 du raidisseur 30 est calée contre un logement de réception 56 embouti dans un raidisseur horizontal central de portière 31 au moyen d'une bande de mastic 58 et la face arrière 60 de cette même partie inférieur 55 est calée contre la face interne 9 du panneau 3 au moyen d'une bande de mastic 59.Referring to Figures 6 and 7, the front face 61 of the lower portion 55 of the stiffener 30 is keyed against a receiving housing 56 stamped in a horizontal central door stiffener 31 by means of a mastic strip 58 and the rear face 60 of the same lower part 55 is wedged against the inner face 9 of the panel 3 by means of a band of mastic 59.
Par ailleurs, les deux branches 34,35 du raidisseur 30 sont bombées en direction de la face interne 9 du panneau 3 de sorte que la partie centrale respective 62a, 62b de ces deux branches 34,35 soit calée contre la face interne 9 du panneau 3 au moyen de bandes de mastic respectives 63a, 63b. La figure 8 présente une variante de l'élément de rigidification 54. Selon cette variante, dans le prolongement de la branche transversale 36, décrite précédemment, le raidisseur présente un décroché 41b dirigé dans la direction opposée à la face interne 9. Les rainures respectives 43,44 des branches 34,35 de ce raidisseur 29 s'étendent le long de ces branches 34,35 directement depuis le décoché 41b.Moreover, the two branches 34, 35 of the stiffener 30 are bulged in the direction of the inner face 9 of the panel 3 so that the respective central portion 62a, 62b of these two branches 34,35 is keyed against the inner face 9 of the panel 3 by means of respective mastic strips 63a, 63b. FIG. 8 shows a variant of the stiffening element 54. According to this variant, in the extension of the transverse branch 36, described above, the stiffener has a stall 41b directed in the direction opposite to the inner face 9. The respective grooves 43,44 branches 34,35 of this stiffener 29 extend along these branches 34,35 directly from the unchecked 41b.
Bien sûr, tout autre élément de rigidification adapté peut être utilisé. De même, au lieu de caler la partie inférieure 55 du raidisseur au moyen d'un mastic, on peut prévoir que cette partie inférieure 55 soit soudée soit directement au fond d'un embouti destiné à recevoir la baguette de flan, dans ce cas il n'y a pas besoin de raidisseur horizontal, soit sur le raidisseur horizontal 31 précédemment décrit.Of course, any other suitable stiffening element can be used. Similarly, instead of wedging the lower portion 55 of the stiffener by means of a putty, it can be provided that the lower portion 55 is welded or directly to the bottom of a stamped to receive the blank rod, in which case it there is no need for horizontal stiffener, or on the horizontal stiffener 31 previously described.
D'un point de vue dimensionnel, la largeur de la branche transversale supérieure 36 est d'environ 150 millimètres et la largeur de la partie inférieure 55 du raidisseur est comprise entre 30 et 50 millimètres.From a dimensional point of view, the width of the upper transverse branch 36 is about 150 millimeters and the width of the lower portion 55 of the stiffener is between 30 and 50 millimeters.
En ce qui concerne le calage du raidisseur 30, au lieu d'un simple calage latéral entre le raidisseur et le panneau de porte comme décrit précédemment, on peut envisager en variante un calage horizontal avec une forme adaptée du raidisseur.As regards the stiffening of the stiffener 30, instead of a simple lateral wedging between the stiffener and the door panel as described above, it is possible to envisage alternatively a horizontal wedging with a suitable shape of the stiffener.
De façon plus générale, le calage est plus ou moins local selon les prestations rigidité recherchées.More generally, the rigging is more or less local depending on the required rigidity services.
Grâce à sa forme en Y et aux nervures 43, 44, le raidisseur de l'invention apporte de la rigidité à la fois dans la zone lécheur et au panneau de porte en entier .With its Y-shape and the ribs 43, 44, the stiffener of the invention provides rigidity to the both in the licking area and the entire door panel.
Par ailleurs, on constate une amélioration acoustique par absence de vibrations du panneau du fait de sa raideur plus importante.Moreover, there is an acoustic improvement by lack of vibration of the panel because of its greater stiffness.
Et bien entendu, la masse a été fortement diminuée par rapport aux raidisseurs connus. And of course, the mass has been greatly reduced compared to known stiffeners.
