Description

ENSEMBLE POUR VEHICULE AUTOMOBILE FACILITANT LE MONTAGE DE CONDUITES NOTAMMENT DE CARBURANT  ASSEMBLY FOR A MOTOR VEHICLE FACILITATING THE MOUNTING OF PIPES IN PARTICULAR FUEL
[0001 ] La présente invention porte sur un ensemble pour véhicule automobile facilitant le montage de conduites, notamment de carburant. L'invention trouve une application particulièrement avantageuse dans le domaine des véhicules automobiles. The present invention relates to a set for a motor vehicle facilitating the assembly of pipes, including fuel. The invention finds a particularly advantageous application in the field of motor vehicles.
[0002] De façon connue en soi, les véhicules à moteur thermique comportent une conduite de carburant reliant le module jauge pompe au rail d'injection du moteur thermique et une conduite de retour de carburant vers un dispositif de recyclage des vapeurs à charbon actif dit "canister" en anglais. In a manner known per se, the heat engine vehicles comprise a fuel line connecting the pump gauge module to the injection rail of the engine and a fuel return line to an activated carbon vapor recycling device said "canister" in English.
[0003] Dans certaines architectures, ces conduites passent à l'intérieur d'un brancard longitudinal du véhicule. Actuellement, des bouchons en plastique destinés à être montés sur un connecteur d'une conduite servent à protéger ladite conduite contre les corps étrangers pendant le transport. Ces bouchons présentent généralement une partie fonctionnelle qui obture la conduite et une languette qui permet de faciliter leur retrait. In some architectures, these pipes pass inside a longitudinal stretcher of the vehicle. Currently, plastic plugs for mounting on a connector of a pipe serve to protect said pipe against foreign bodies during transport. These plugs generally have a functional portion that closes the pipe and a tongue that facilitates their removal.
[0004] Le brancard peut comporter un ou plusieurs écrous soudés à l'intérieur du corps creux du brancard pour permettre la fixation d'éléments structurels du véhicule, tels qu'une barre de renfort ou un support de batterie pour les véhicules hybrides. Toutefois, la présence de ces écrous rend difficile l’installation des conduites de carburant, dans la mesure où ces conduites se bloquent sur des arêtes vives des écrous qui obstruent le volume interne du brancard. The stretcher may comprise one or more welded nuts inside the hollow body of the stretcher to allow the attachment of structural elements of the vehicle, such as a reinforcing bar or a battery holder for hybrid vehicles. However, the presence of these nuts makes it difficult to install the fuel lines, insofar as these pipes are blocked on sharp edges of the nuts that obstruct the internal volume of the stretcher.
[0005] L'invention vise à résoudre ce problème de montage en proposant un ensemble pour véhicule automobile comportant: The invention aims to solve this mounting problem by providing a set for a motor vehicle comprising:
- un élément structurel ayant un volume creux à l'intérieur duquel sont destinées à passer des conduites, notamment de carburant,  a structural element having a hollow volume inside which are intended to pass conduits, in particular of fuel,
- au moins un organe de fixation obturant partiellement le volume creux et plaqué contre une face interne de l'élément structurel, et  at least one fastener partially closing the hollow volume and pressed against an internal face of the structural element, and
- une plaque d'évitement de l'organe de fixation comportant au moins une portion ayant une hauteur variant progressivement lorsque l'on se déplace de la face interne de l'élément structurel vers une portion sommitale de la plaque d'évitement disposée au-dessus de l'organe de fixation. [0006] L’invention permet ainsi, par la mise en place de la plaque d'évitement à l'intérieur du brancard, de faciliter l’introduction des conduites à l'intérieur d'un brancard en évitant l’obstacle constitué notamment par les écrous soudés. an avoidance plate of the fastening member comprising at least one portion having a gradually varying height when moving from the internal face of the structural element to a top portion of the avoidance plate disposed above the fastener. The invention thus makes it possible, by placing the avoidance plate inside the stretcher, to facilitate the introduction of the lines inside a stretcher avoiding the obstacle constituted in particular by welded nuts.
[0007] Selon une réalisation, la portion de hauteur variable est une rampe. In one embodiment, the portion of variable height is a ramp.
[0008] Selon une réalisation, la rampe est droite. In one embodiment, the ramp is straight.
[0009] Selon une réalisation, la plaque d'évitement comporte deux extrémités de fixation sur la face interne de l'élément structurel. In one embodiment, the avoidance plate has two attachment ends on the inner face of the structural element.
[0010] Selon une réalisation, la plaque d'évitement est symétrique par rapport à un plan médian transversal. In one embodiment, the avoidance plate is symmetrical with respect to a transverse median plane.
[0011] Selon une réalisation, l'organe de fixation est un écrou permettant la fixation d'une barre de renfort ou d'un support de batterie. In one embodiment, the fastener is a nut for fixing a reinforcing bar or a battery holder.
[0012] Selon une réalisation, l'élément structurel creux est un brancard. In one embodiment, the hollow structural member is a stretcher.
[0013] L'invention a également pour objet un procédé d'installation d'au moins une conduite, notamment de carburant, à l'intérieur d'un véhicule automobile, caractérisé en ce qu'il comporte: The invention also relates to a method for installing at least one pipe, in particular fuel, inside a motor vehicle, characterized in that it comprises:
- une étape de montage d'une plaque d'évitement à l'intérieur d'un volume creux d'un élément structurel, la plaque d'évitement étant disposée au-dessus d'au moins un organe de fixation,  a step of mounting an avoidance plate inside a hollow volume of a structural element, the avoidance plate being disposed above at least one fastener,
- une étape d'introduction de conduites à l'intérieur de l'élément structurel creux par une extrémité d'entrée,  a step of introducing pipes inside the hollow structural element by an inlet end,
- une étape de récupération en sous-caisse des conduites par une extrémité de sortie de l'élément structurel creux, et  a step of sub-reclaiming the pipes by an exit end of the hollow structural element, and
- une étape de connexion des conduites avec un réservoir à carburant.  - a step of connecting the pipes with a fuel tank.
[0014] L’invention sera mieux comprise à la lecture de la description qui suit et à l’examen des figures qui l’accompagnent. Ces figures ne sont données qu’à titre illustratif mais nullement limitatif de l’invention. The invention will be better understood on reading the description which follows and the examination of the figures that accompany it. These figures are given for illustrative but not limiting of the invention.
[0015] La figure 1 est une vue en perspective d'un brancard à l'intérieur duquel sont destinées à passer des conduites de carburant; [0016] La figure 2 est une vue détaillée de la zone du brancard obturée partiellement par des écrous permettant la fixation d'une barre de renfort et d'un support de batterie; Figure 1 is a perspective view of a stretcher within which are intended to pass fuel lines; Figure 2 is a detailed view of the area of the stretcher partially closed by nuts for fixing a reinforcing bar and a battery holder;
[0017] La figure 3a est une vue en perspective de la plaque d'évitement selon l'invention montée à l'intérieur d'un brancard et vue par transparence; Figure 3a is a perspective view of the avoidance plate according to the invention mounted inside a stretcher and viewed by transparency;
[0018] Les figures 3b et 3c sont des vues détaillées en perspective et de côté d'une plaque d'évitement des écrous disposés à l'intérieur du brancard. Figures 3b and 3c are detailed views in perspective and side of an avoidance plate nuts arranged inside the stretcher.
[0019] Les éléments identiques similaires ou analogues conservent la même référence d'une figure à l'autre. Similar or similar identical elements retain the same reference from one figure to another.
[0020] La figure 1 montre un brancard 10 de véhicule destiné à s'étendre parallèlement à un axe longitudinal du véhicule. Ce brancard 10 présente un corps creux à l'intérieur duquel passent des conduites de carburant 12. En particulier, on distingue une conduite 12 de carburant reliant le module jauge pompe au rail d'injection du moteur thermique et une conduite 12 de retour de carburant vers un dispositif de recyclage des vapeurs à charbon actif dit "canister" en anglais. Figure 1 shows a vehicle stretcher 10 intended to extend parallel to a longitudinal axis of the vehicle. This stretcher 10 has a hollow body inside which passes fuel lines 12. In particular, there is a fuel line 12 connecting the pump gauge module to the injection rail of the engine and a pipe 12 of fuel return to a device for recycling activated carbon vapors called "canister" in English.
[0021 ] Ces conduites 12 sortent du brancard 10 pour déboucher d'un côté à l'intérieur du compartiment moteur via un passe-gaine 16 pour permettre leur raccord sur le moteur thermique et d'un autre côté vers l'arrière du véhicule pour permettre leur raccord avec le réservoir à carburant. These pipes 12 out of the stretcher 10 to open on one side inside the engine compartment via a sheath 16 to allow their connection to the engine and on the other side towards the rear of the vehicle for allow their connection with the fuel tank.
[0022] Comme on peut le voir plus clairement sur la figure 2, le brancard 10 comporte en outre deux organes de fixation 20, en l'occurrence deux écrous, soudés à l'intérieur du corps creux du brancard 10. Un des écrous 20 permet la fixation d'une barre de renfort qui transmet des efforts entre le berceau et le plancher du véhicule en cas de choc. Un autre écrou 20 est utilisé pour assurer la fixation d'un support de batterie 18. Ces écrous 20 obturent partiellement le volume creux du brancard 10 et sont plaqués contre une face interne du brancard 10. As can be seen more clearly in Figure 2, the stretcher 10 further comprises two fasteners 20, in this case two nuts, welded inside the hollow body of the stretcher 10. One of the nuts 20 allows the attachment of a reinforcing bar which transmits forces between the cradle and the floor of the vehicle in case of impact. Another nut 20 is used to secure a battery holder 18. These nuts 20 partially seal the hollow volume of the stretcher 10 and are pressed against an inner face of the stretcher 10.
[0023] Afin de faciliter le passage des conduites 12 à l'intérieur du volume creux du brancard 10, une plaque d'évitement 22 des écrous 20 visible sur les figures 3a, 3b, et 3c est utilisée pour recouvrir lesdits écrous 20. Cette plaque d'évitement 22 vise à recouvrir les arêtes vives des écrous 20 susceptibles de bloquer les conduites 12 lors de leur insertion à l'intérieur du brancard 10. [0024] A cet effet, comme cela est représenté sur les figures 3a à 3c, la plaque d'évitement 22 comporte deux portions 22.1 de hauteur variable disposées de part et d'autre d'une portion sommitale 22.2 s'étendant au-dessus des écrous 20. Chaque portion 22.1 présente une hauteur variant progressivement lorsque l'on se déplace de la face interne 21 du brancard 10 vers la portion sommitale 22.2. Dans l'exemple représenté, les deux portions 22.1 présentent une forme de rampe droite formant un plus petit angle A avec la face interneTo facilitate the passage of the pipes 12 inside the hollow volume of the stretcher 10, an avoidance plate 22 of the nuts 20 visible in Figures 3a, 3b, and 3c is used to cover said nuts 20. This avoidance plate 22 is intended to cover the sharp edges of the nuts 20 which can block the pipes 12 during their insertion inside the stretcher 10. For this purpose, as shown in Figures 3a to 3c, the avoidance plate 22 comprises two portions 22.1 of variable height disposed on either side of a top portion 22.2 extending above 20. Each portion 22.1 has a gradually varying height when moving from the inner face 21 of the stretcher 10 to the top portion 22.2. In the example shown, the two portions 22.1 have a straight ramp shape forming a smaller angle A with the inner face
21 compris par exemple entre 5 et 45 degrés (cf. figures 3b et 3c). En variante, les portions 22.1 pourront présenter une forme de rampe incurvée. La portion sommitale 22.2 s'étend en l'occurrence sensiblement parallèlement à la face interne 21 du brancard 10 mais pourrait en variante présenter elle aussi une légère pente. 21 for example between 5 and 45 degrees (see Figures 3b and 3c). Alternatively, the portions 22.1 may have a curved ramp shape. The top portion 22.2 extends in this case substantially parallel to the inner face 21 of the stretcher 10 but could alternatively also have a slight slope.
[0025] Les portions 22.1 sont prolongées chacune par une extrémité de fixation 22.3 sur la face interne 21 du brancard 10. Ces extrémités 22.3 sont disposées de part et d'autre de l'ensemble des deux écrous 20. Avantageusement, les extrémités 22.3 sont soudées sur la face interne 21 du corps creux du brancard 10, et ce avant que le brancard 10 soit fixé au plancher du véhicule. En variante, les extrémités 22.3 pourront être fixées par vissage, rivetage, collage ou toute autre technique de fixation adaptée à l'application. The portions 22.1 are each extended by an attachment end 22.3 on the inner face 21 of the stretcher 10. These ends 22.3 are disposed on either side of the set of two nuts 20. Advantageously, the ends 22.3 are welded on the inner face 21 of the hollow body of the stretcher 10, and before the stretcher 10 is attached to the floor of the vehicle. Alternatively, the ends 22.3 may be fixed by screwing, riveting, gluing or any other fastening technique suitable for the application.
[0026] Le type de fixation dépend toutefois de l'environnement d'implantation de la plaqueThe type of attachment, however, depends on the implantation environment of the plate
22 dans le véhicule. Ainsi, une solution vissée sera à éviter dans le cas où la zone de fixation de la plaque 22 se situe à proximité d'une limite de garde au sol du véhicule, dans la mesure où un tel mode de fixation impliquerait de prévoir des écrous soudés dans le brancard 10 augmentant l'encombrement vertical du véhicule. 22 in the vehicle. Thus, a screwed solution will be avoided in the case where the fixing area of the plate 22 is close to a limit of ground clearance of the vehicle, insofar as such a method of attachment imply to provide welded nuts in the stretcher 10 increasing the vertical dimensions of the vehicle.
[0027] De préférence, afin de faciliter sa fabrication, la plaque d'évitement 22 est symétrique par rapport à un plan médian transversal P. Suivant une réalisation, la plaque 22 pourra être obtenue par pliage d'une tôle. Preferably, to facilitate its manufacture, the avoidance plate 22 is symmetrical with respect to a transverse median plane P. In one embodiment, the plate 22 may be obtained by folding a sheet.
[0028] On décrit ci-après l'installation des conduites de carburant 12 à l'intérieur d'un véhicule automobile. Dans un premier temps, la plaque d'évitement 22 est montée à l'intérieur du volume creux du brancard 10, de sorte que la plaque d'évitement 22 recouvre les écrous 20. A cet effet, les extrémités 22.3 sont de préférence soudées sur la face interne 21 du brancard 10 avant que le brancard 10 soit fixé au plancher du véhicule. Hereinafter is described the installation of fuel lines 12 inside a motor vehicle. In a first step, the avoidance plate 22 is mounted inside the hollow volume of the stretcher 10, so that the avoidance plate 22 covers the nuts 20. For this purpose, the ends 22.3 are preferably welded on the inner face 21 of the stretcher 10 before the stretcher 10 is attached to the floor of the vehicle.
[0029] Les conduites 12 sont ensuite introduites à l'intérieur du brancard creux 10 par une extrémité d'entrée 10.1 (cf. figure 1 ). Les conduites 12 sont insérées via leur connecteur d'extrémité respectif. Les connecteurs d'extrémité des conduites 12 pourront glisser suivant la rampe 22.1 à pente progressive tournée vers l'entrée 10.1 , puis suivant la portion sommitale 22.2 en surélévation par rapport à la face interne 21 du brancard 10, puis suivant la rampe 22.1 opposée. The pipes 12 are then introduced into the hollow stretcher 10 by an inlet end 10.1 (see Figure 1). The pipes 12 are inserted via their respective end connectors. The end connectors of the pipes 12 can slide following the ramp 22.1 with a gradual slope facing the inlet 10.1, then following the summit portion 22.2 in elevation relative to the inner face 21 of the stretcher 10, then following the ramp 22.1 opposite.
[0030] Les conduites 12 sont ensuite récupérées en sous-caisse par une extrémité de sortie 10.2 du brancard 10 et connectées avec le réservoir à carburant. The pipes 12 are then recovered under the box by an output end 10.2 of the stretcher 10 and connected with the fuel tank.
[0031] L’invention permet ainsi, en utilisant la plaque d'évitement 22, de faciliter l’introduction des conduites 12 à l'intérieur d'un brancard 10 en évitant le phénomène de blocage dû aux écrous 20. The invention thus makes it possible, by using the avoidance plate 22, to facilitate the introduction of the pipes 12 inside a stretcher 10 while avoiding the phenomenon of blockage due to the nuts 20.
[0032] En variante, les organes de fixation 20 disposés à l'intérieur du brancard 10 sont des organes autres que des écrous. Alternatively, the fasteners 20 disposed within the stretcher 10 are bodies other than nuts.
[0033] En variante, l'élément structurel à travers lequel passe les conduites 12 pourra être un élément autre qu'un brancard 10. In a variant, the structural element through which the ducts 12 pass may be an element other than a stretcher 10.
[0034] En variante, la plaque d'évitement 22 comporte une seule rampe 22.1 tournée vers l'extrémité d'entrée 10.1 du brancard 10, l'autre rampe étant alors supprimée. Alternatively, the avoidance plate 22 comprises a single ramp 22.1 facing the input end 10.1 of the stretcher 10, the other ramp then being removed.
