Description

Elément de fixation d'un orciane fonctionnel pour véhicule automobile Fastening element of a functional orciane for a motor vehicle

La présente invention concerne un élément de fixation d'un organe fonctionnel à une peau de pare-chocs d'un véhicule automobile, l'élément comportant une zone de maintien de l'organe fonctionnel, et une plaque de liaison à une zone de réception de la peau de pare-chocs, pourvu d'un moyen de fixation. Un tel élément de fixation est connu du document EP2006163 Al. Ce document décrit une partie d'adaptation destinée à la fixation d'un organe fonctionnel sur une peau de pare-chocs. La partie d'adaptation comprend une zone de maintien de l'organe fonctionnel ainsi qu'une zone d'interface. L'organe fonctionnel est fixé à la peau de pare-chocs en encliquetant la zone d'interface de la partie d'adaptation sur une zone d'accueil dédiée et complémentaire d'une pièce support intermédiaire rapportée sur la peau de pare-chocs. The present invention relates to an element for fastening a functional member to a bumper skin of a motor vehicle, the element comprising a holding zone of the functional member, and a connecting plate to a receiving zone. the bumper skin, provided with a fastening means. Such a fastener is known from EP2006163 A1. This document describes an adaptation part intended for fixing a functional member on a bumper skin. The adaptation portion includes a holding region of the functional member and an interface zone. The functional member is attached to the bumper skin by snapping the interface area of the fitting portion on a dedicated and complementary receiving area of an intermediate support member attached to the bumper skin.

Cette solution connue a les inconvénients suivants. Premièrement, la partie d'adaptation est inutilisable en l'absence de la pièce support intermédiaire rapportée sur la peau de pare-chocs. Il est impossible de fixer l'organe fonctionnel sur la peau de pare-chocs en utilisant la seule partie d'adaptation. Deuxièmement, l'organe fonctionnel peut uniquement être fixé à un endroit bien défini de la peau de pare-chocs, disposant d'une zone d'accueil dédiée. Il est impossible de fixer l'organe fonctionnel à un endroit quelconque de la peau de pareûchocs ou d'en faire varier la position. Un but de l'invention est donc de proposer un élément de fixation d'un organe fonctionnel sur une peau de pare-chocs qui soit simple et permette une fixation de l'organe fonctionnel à un endroit quelconque de la peau de pare-chocs. Afin d'atteindre ce but, l'invention propose un élément de fixation du type précité, caractérisé en ce que la plaque de liaison est conformable à la géométrie de la zone de réception. Grâce à la plaque conformable, l'élément de fixation peut s'adapter à la géométrie locale du lieu de fixation à la peau de pare-chocs. Ainsi, l'élément de fixation selon l'invention est très polyvalent. Ce même type d'élément de fixation peut servir à équiper une peau de pare-chocs à géométrie variable d'une pluralité d'organes fonctionnels ou être utilisé pour fixer un type d'organe fonctionnel sur différentes peaux de pare-chocs comportant chacune une géométrie spécifique. L'élément de fixation selon l'invention peut notamment être utilisé indépendamment du degré de courbure local de la zone de réception de la peau de pare-chocs. This known solution has the following drawbacks. First, the adaptation part is unusable in the absence of the intermediate support part reported on the bumper skin. It is impossible to fix the functional body on the bumper skin using the only fitting part. Second, the functional body can only be attached to a well-defined area of the bumper skin, having a dedicated docking area. It is impossible to fix the functional organ anywhere on the bumper skin or to vary its position. An object of the invention is therefore to provide a fastener of a functional member on a bumper skin which is simple and allows a fixation of the functional member at any point of the bumper skin. In order to achieve this object, the invention proposes a fastening element of the aforementioned type, characterized in that the connecting plate is conformable to the geometry of the receiving zone. Thanks to the conformable plate, the fastening element can adapt to the local geometry of the place of attachment to the bumper skin. Thus, the fastening element according to the invention is very versatile. This same type of fastener may be used to equip a variable geometry bumper skin of a plurality of functional members or be used to attach a type of functional member to different bumper skins each having a specific geometry. The fastening element according to the invention may in particular be used independently of the degree of local curvature of the zone of reception of the bumper skin.

L'invention concerne aussi un procédé de montage du pare-chocs comprenant les étapes : - fourniture de la peau de pare-chocs et de l'élément de fixation, et éventuellement de l'élément de fixation supplémentaire, - fixation de la plaque de liaison à la zone de réception en conformant la plaque de liaison à la géométrie de la zone de réception, et éventuellement une fixation de la plaque de liaison supplémentaire à la zone de réception supplémentaire en conformant la plaque de liaison supplémentaire à la géométrie de la zone de réception supplémentaire. De préférence, la fixation de la ou chaque plaque de liaison à la zone de réception est effectuée en déformant élastiquement la plaque de liaison. L'invention et ces avantages seront mieux compris à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés sur lesquels : - La figure 1 est une vue avant et en perspective d'un élément de fixation selon l'invention ; - La figure 2 est une vue arrière et en perspective de l'élément de fixation de la figure 1 ; -La figure 3 est une vue en perspective de la face arrière d'une peau de pare-chocs avec quatre éléments de fixation selon l'invention ; - La figure 4 est une vue en section selon les flèches IV de la figure 3 ; et - La figure 5 est une vue en section selon les flèches V de la figure 3. Dans le contexte de la présente demande, les termes « avant », « arrière », « supérieure », « inférieure », « gauche », « droite » etc... s'entendent en référence au repère orthogonal usuel des véhicules automobiles comprenant (cf.la figure 3) : - Un axe longitudinal X, horizontal et dirigé de l'arrière vers l'avant ; - Un axe transversal Y horizontal et dirigé de la droite vers la gauche ; et -Un axe vertical Z dirigé du bas vers le haut. La figure 1 est une vue en perspective d'un élément de fixation 2 selon l'invention. Cet élément 2 sert à fixer un organe fonctionnel, tel qu'un capteur à ultra-sons, à l'arrière de la peau de pare-chocs d'un véhicule automobile. L'élément 2 comprend une plaque de liaison 4, une zone 6 de maintien de l'organe fonctionnel, et un moyen de fixation 8a, 8b. La plaque de liaison 4 et la zone de maintien 6 sont de préférence d'un seul tenant et faits de matière thermoplastique. The invention also relates to a method of mounting the bumper comprising the steps of: - supplying the bumper skin and the fixing element, and possibly the additional fastening element, - fixing the bumper plate; connecting to the receiving area by shaping the connecting plate to the geometry of the receiving area, and possibly attaching the additional connecting plate to the additional receiving area by shaping the additional connecting plate to the geometry of the area additional reception. Preferably, the attachment of the or each connecting plate to the receiving zone is effected by elastically deforming the connecting plate. The invention and these advantages will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings in which: FIG. 1 is a front and perspective view of a fastening element according to the invention; - Figure 2 is a rear view and in perspective of the fastener of Figure 1; FIG. 3 is a perspective view of the rear face of a bumper skin with four fixing elements according to the invention; - Figure 4 is a sectional view along the arrows IV of Figure 3; and FIG. 5 is a sectional view along the arrows V of FIG. 3. In the context of the present application, the terms "before", "back", "upper", "lower", "left", " "etc." are understood by reference to the usual orthogonal reference of motor vehicles comprising (see Figure 3): - A longitudinal axis X, horizontal and directed from the rear to the front; - A transverse Y horizontal axis and directed from right to left; and a vertical axis Z directed from bottom to top. Figure 1 is a perspective view of a fastener element 2 according to the invention. This element 2 serves to fix a functional member, such as an ultrasonic sensor, at the rear of the bumper skin of a motor vehicle. The element 2 comprises a connecting plate 4, a zone 6 for holding the functional member, and a fastening means 8a, 8b. The connecting plate 4 and the holding zone 6 are preferably integral and made of thermoplastic material.

En référence à la figure 2, la zone de maintien 6 s'étend vers l'arrière selon un axe principal A. L'axe A est sensiblement normal à la surface arrière 10 de la plaque de liaison 4. La zone de maintien peut être qualifiée de douille 6a dont l'embase 12 borde un trou 14 pratiqué au centre de la plaque de liaison 4. With reference to FIG. 2, the holding zone 6 extends rearward along a principal axis A. The axis A is substantially normal to the rear surface 10 of the connecting plate 4. The holding zone can be characterized bush 6a whose base 12 borders a hole 14 formed in the center of the connecting plate 4.

L'embase 12 de forme généralement annulaire est munie le long de sa circonférence de cinq saillies 16a à 16e. La plaque de liaison 4 a une forme sensiblement rectangulaire avec une partie centrale 18 comportant le trou 14 et deux ailettes 20a et 20b s'étendant de part et d'autre de la partie centrale 18. L'épaisseur E de la plaque de liaison 4 est choisie de manière à pouvoir déformer élastiquement les ailettes 20a et 20b. De préférence l'épaisseur E est inférieure ou égale à 1,5 mm. Chaque ailette 20a, 20b est pourvue d'un moyen de fixation 8a, 8b permettant de rattacher l'élément de fixation 2 à la surface d'une peau de pare-chocs. De préférence, les moyens de fixation, 8a, 8b sont des bandes ou films adhésives de forme rectangulaire 9a, 9b. Néanmoins, d'autres moyens de fixation ou adhésifs sont envisageables. Les figures 3 à 5 illustrent l'utilisation de l'élément de fixation 2 selon les figures 1 et 2 pour la fixation de quatre capteurs à ultra-sons le long de la face arrière 22 d'une peau de pare-chocs 24. The base 12 of generally annular shape is provided along its circumference five projections 16a to 16e. The connecting plate 4 has a substantially rectangular shape with a central portion 18 having the hole 14 and two fins 20a and 20b extending on either side of the central portion 18. The thickness E of the connecting plate 4 is chosen so as to be able to elastically deform the fins 20a and 20b. Preferably the thickness E is less than or equal to 1.5 mm. Each fin 20a, 20b is provided with a fastening means 8a, 8b for attaching the fastening element 2 to the surface of a bumper skin. Preferably, the fixing means, 8a, 8b are strips or adhesive films of rectangular shape 9a, 9b. Nevertheless, other fastening means or adhesives are possible. FIGS. 3 to 5 illustrate the use of the fastening element 2 according to FIGS. 1 and 2 for fixing four ultrasonic sensors along the rear face 22 of a bumper skin 24.

A la figure 3, on distingue quatre ensembles 26 agencés respectivement à l'extrême droite, à droite, à gauche, et à l'extrême gauche le long d'une courbe horizontale sur la surface 22 de la peau de pare-chocs 24. Chaque ensemble 26 comporte un élément de fixation 2 recevant un capteur à ultra-sons 28 (cf. la figure 4). In FIG. 3, there are four sets 26 arranged respectively on the far right, on the right, on the left and on the far left along a horizontal curve on the surface 22 of the bumper skin 24. Each assembly 26 comprises a fixing element 2 receiving an ultrasound sensor 28 (see FIG.

La figure 4 et la figure 5 sont des vues en section selon le plan horizontal xy, la figure 4 montrant en détail l'agencement sur la peau de pare-chocs 24 de l'ensemble 26 d'extrême gauche, et la figure 5 montrant en détail l'agencement sur la peau de pare-chocs 24 de l'ensemble 26 de droite. En référence à la figure 4, un capteur à ultra-sons 28 est logé en partie au sein de la zone de maintien 6. Sa section d'émission/réception d'ultra-sons 32 traverse un trou 34 aménagé dans la zone de réception 30 de la peau de pare-chocs 24. Les films adhésifs 9a et 9b adhèrent à la surface arrière de la zone de réception 30. La plaque de liaison 4 épouse, par déformation élastique, la forme locale de la face arrière de la zone de réception 30. Notamment, la plaque de liaison 4 retrace le galbe de la zone de réception 30. La déformation est sensiblement exclusivement élastique et non pas plastique. En référence à la figure 5, on distingue un autre capteur à ultra-sons 28 fixé à la peau de pare-chocs 24 par un élément de fixation 2 supplémentaire du même type. On notera que dans cette partie de la peau de pare-chocs 24, la courbure dans le plan xy de la zone de réception 30 supplémentaire est quasi-nulle. En d'autres termes, la zone de réception 30 supplémentaire suit sensiblement une droite s'étendant selon l'axe transversal Y. La plaque de liaison 4, qui se conforme à cette géométrie, est donc sensiblement plane avec une courbure négligeable. L'élément de fixation 2 décrit ci-dessus peut être utilisé dans un procédé de montage de pare-chocs comprenant les étapes suivantes : - fourniture de la peau de pare-chocs 24 et de l'élément de fixation 2, et éventuellement d'un l'élément de fixation 2 supplémentaire, - fixation de la plaque de liaison 4 à une zone de réception 30 en conformant la plaque de liaison à la géométrie de la zone de réception, et éventuellement - fixation de la plaque de liaison 4 de l'élément de fixation 2 supplémentaire à une zone de réception 30 supplémentaire en conformant la plaque de liaison supplémentaire à la géométrie de la zone de réception 30 supplémentaire. La fixation de la ou de chaque plaque de liaison 4 à la zone de réception 30 associée est effectuée en déformant élastiquement la plaque de liaison. L'élément de fixation 2 selon l'invention est très versatile. En effet, grâce à la plaque de liaison 4 conformable munie de bandes adhésives 9a, 9b, il permet de fixer un organe fonctionnel presque n'importe où sur une peau de pare-chocs quelconque, sans avoir besoin de moyen d'adaptation. La déformation élastique s'étend notamment avec une déformation plastique inférieure à 0,2%.30 FIG. 4 and FIG. 5 are sectional views along the horizontal plane xy, FIG. 4 showing in detail the arrangement on the bumper skin 24 of the far left assembly 26, and FIG. in detail the arrangement on the bumper skin 24 of the assembly 26 on the right. With reference to FIG. 4, an ultrasound sensor 28 is housed partly within the holding zone 6. Its ultrasound transmission / reception section 32 passes through a hole 34 arranged in the reception zone. Bead skin 24. The adhesive films 9a and 9b adhere to the rear surface of the receiving zone 30. The connecting plate 4 marries, by elastic deformation, the local shape of the rear face of the zone of the bumper skin. In particular, the connecting plate 4 traces the curve of the receiving zone 30. The deformation is substantially exclusively elastic and not plastic. Referring to Figure 5, there is another ultrasonic sensor 28 attached to the bumper skin 24 by an additional fastener 2 of the same type. Note that in this part of the bumper skin 24, the curvature in the xy plane of the additional receiving zone 30 is almost zero. In other words, the additional receiving zone 30 substantially follows a line extending along the transverse axis Y. The connecting plate 4, which conforms to this geometry, is therefore substantially planar with a negligible curvature. The fixing element 2 described above can be used in a bumper mounting method comprising the following steps: - supplying the bumper skin 24 and the fixing element 2, and possibly an additional fixing element 2, - fixing the connecting plate 4 to a receiving zone 30 by shaping the connecting plate to the geometry of the receiving zone, and possibly - fixing the connecting plate 4 of the additional securing member 2 to an additional receiving area 30 conforming the additional connecting plate to the geometry of the additional receiving area. Fixing the or each connecting plate 4 to the associated receiving zone 30 is effected by elastically deforming the connecting plate. The fastening element 2 according to the invention is very versatile. Indeed, thanks to the conformable connecting plate 4 provided with adhesive strips 9a, 9b, it allows to fix a functional member almost anywhere on any bumper skin, without the need for adaptation means.
