Description

Face avant de véhicule automobile à accessibilité amélioréeMotor vehicle front panel with improved accessibility
L'invention concerne une face avant de véhicule automobile du type comprenant un support propre à recevoir des équipements et à être fixé sur la structure du véhicule.The invention relates to a front face of a motor vehicle of the type comprising a support suitable for receiving equipment and for being fixed to the structure of the vehicle.
Une face avant, appelée aussi façade avant, est un élément de structure destiné à supporter divers équipements du véhicule, tels que projecteurs, clignotants, avertisseur sonore, module d'échange de chaleur, groupe moto-ventilateur, etc.A front face, also called front face, is a structural element intended to support various vehicle equipment, such as headlights, indicators, horn, heat exchange module, motor-fan unit, etc.
La face avant, ainsi pourvue de ses équipements, constitue un module unitaire préparé et livré par l'équipementier et prêt à être monté sur le véhicule par le constructeur. Le montage de ce module unitaire se fait par raccordement à des éléments de structure latéraux du véhicule, tels que longerons, ailes ou coque, puis mise en place d'un pare-choc ou bouclier frontal rapporté sur le module.The front panel, thus provided with its equipment, constitutes a unitary module prepared and delivered by the supplier and ready to be mounted on the vehicle by the manufacturer. The mounting of this unitary module is done by connection to lateral structural elements of the vehicle, such as side rails, wings or hull, then fitting of a bumper or frontal shield attached to the module.
Une telle face avant est généralement réalisée sous la forme d'un élément monobloσ, en particulier sous la forme d'un élément composite métal/plastique. Il est connu en effet, notamment d'après la publication EP-A-0 658 470, de réaliser une face avant sous la forme d'une armature métallique en tôle emboutie, sur laquelle est surmoulée une matière plastique, en particulier du type polyamide.Such a front face is generally produced in the form of a monobloσ element, in particular in the form of a metal / plastic composite element. It is in fact known, in particular from publication EP-A-0 658 470, to produce a front face in the form of a metal frame of stamped sheet metal, on which is molded a plastic material, in particular of the polyamide type. .
Une face avant est habituellement composée d'une traverse supérieure horizontale reliée . à deux montants sensiblement verticaux, lesquels sont généralement reliés entre eux par une traverse inférieure. Dans le volume ainsi défini entre la traverse supérieure, les montants et, le cas échéant, la traverse inférieure, est logé un module d'échange de chaleur. Celui-ci est constitué soit seulement par le radiateur de refroidissement du moteur, soit le plus souvent par le radiateur de refroidissement du moteur et un condenseur de climatisation.A front face is usually composed of a connected horizontal upper crosspiece. two substantially vertical uprights, which are generally connected together by a lower cross member. In the volume thus defined between the upper cross member, the uprights and, if necessary, the lower cross member, is housed a heat exchange module. This is constituted either only by the engine cooling radiator, or more often by the engine cooling radiator and air conditioning condenser.
De plus, dans les deux emplacements définis sous la traverse supérieure, de part et d'autre des montants, sont placés les projecteurs du véhicule.In addition, in the two locations defined under the upper cross member, on either side of the uprights, the vehicle headlights are placed.
Dans les véhicules automobiles actuels, la place' dévolue aux équipements est de plus en plus limitée compte tenu du nombre croissant des équipements, ce qui pose un problème d'encombrement et d'accessibilité, notamment pour les équipements se trouvant dans le compartiment moteur.In current motor vehicles, the space allocated to equipment is more and more limited taking into account the increasing number of equipment, which poses a problem of space and accessibility, in particular for the equipment located in the engine compartment.
Or, il est indispensable que des volumes libres soient aménagés pour accéder aux équipements, notamment en vue de leur maintenance.However, it is essential that free volumes be fitted to access the equipment, in particular for its maintenance.
Ainsi, un volume doit être créé derrière chaque projecteur pour donner accès au capot de boîtier du projecteur afin de pouvoir manipuler les lampes, les douilles et le faisceau électrique.Thus, a volume must be created behind each projector to give access to the housing cover of the projector in order to be able to handle the lamps, the sockets and the electric harness.
Dans la plupart des solutions existantes, un volume minimal est aménagé par conception derrière le boîtier de projecteur afin de manipuler les éléments nécessaires. Il en résulte pour inconvénient la création d'un volume perdu dans le compartiment moteur aux emplacements des projecteurs.In most existing solutions, a minimum volume is designed by design behind the projector housing in order to handle the necessary elements. This results in the drawback of creating a volume lost in the engine compartment at the locations of the headlights.
On connaît aussi des solutions consistant à prévoir une mobilité du projecteur, soit par dépose complète, soit par un mouvement de rotation. Toutefois, cette dépose ou mobilité du projecteur impose un maintien mécanique et une bonne remise en position, ce qui entraîne des pièces supplémentaires et donc un surcoût.There are also known solutions consisting in providing mobility of the projector, either by complete removal, or by a rotational movement. However, this removal or mobility of the projector requires mechanical maintenance and good repositioning, which results in additional parts and therefore an additional cost.
Le problème se pose aussi pour le remplacement des echangeurs de chaleur, qui nécessite le démontage d'un grand nombre de composants et grève donc le coût des réparations.The problem also arises for the replacement of heat exchangers, which requires the disassembly of a large number of components and therefore strike the cost of repairs.
L'invention a notamment pour but de surmonter les inconvénients précités .The object of the invention is in particular to overcome the aforementioned drawbacks.
Elle vise notamment à procurer une face avant de véhicule automobile facilitant l'accès à certains équipements, en supprimant les volumes morts inutiles.It aims in particular to provide a front face of a motor vehicle facilitating access to certain equipment, by eliminating unnecessary dead volumes.
Elle propose à cet effet une face avant de véhicule automobile, du type défini ci-dessus, dans laquelle le support comprend une partie inférieure propre à être fixée à la structure du véhicule et une partie supérieure formant une traverse supérieure et montée mobile par rapport à la partie inférieure entre une position rapprochée, en laquelle la partie supérieure est rabattue contre la partie inférieure pour former un ensemble unitaire, et une position éloignée en laquelle la partie supérieure est espacée de la partie inférieure pour faciliter l'accès aux équipements.To this end, it offers a front face of a motor vehicle, of the type defined above, in which the support comprises a lower part capable of being fixed to the structure of the vehicle and an upper part forming an upper cross member and mounted movable relative to the lower part between a close position, in which the upper part is folded against the lower part to form a unitary assembly, and a distant position in which the upper part is spaced from the lower part to facilitate access to the equipment.
Ainsi, dans la position rapprochée, la partie supérieure et la partie inférieure forment un ensemble unitaire résistant qui est comparable à une face avant traditionnelle. Par contre, dans la position éloignée, la partie supérieure se trouve espacée de la partie inférieure, ce qui facilite l'accès aux équipements. Dans ces conditions, il n'est plus nécessaire de' prévoir des espaces morts inutiles, notamment au niveau des projecteurs et du ou des échangeur(s) de chaleur.Thus, in the close position, the upper part and the lower part form a resistant unitary assembly which is comparable to a traditional front face. On the other hand, in the remote position, the upper part is spaced from the lower part, which facilitates access to the equipment. In these conditions it is no longer necessary to 'provide unnecessary dead space, especially in the headlights and or exchange (s) of heat.
Dans une forme de réalisation préférée de l'invention, la partie supérieure est montée pivotante par rapport à la partie inférieure autour d'un axe transversal du véhicule. Toutefois, il est envisageable aussi de prévoir que la partie supérieure soit montée mobile d'une autre manière, par exemple par coulissèment, par rapport à la partie inférieure. D'autres caractéristiques complémentaires ou alternatives de l'invention sont les suivantes :In a preferred embodiment of the invention, the upper part is pivotally mounted relative to the lower part about a transverse axis of the vehicle. However, it is also conceivable to provide that the upper part is mounted movable in another way, for example by sliding, relative to the lower part. Other complementary or alternative characteristics of the invention are the following:
- la partie supérieure et la partie inférieure sont reliées entre elles par deux articulations alignées sur l'axe transversal ;- The upper part and the lower part are connected together by two articulations aligned on the transverse axis;
- les articulations sont espacées l'une de l'autre et situées aux extrémités de la partie inférieure et aux extrémités de la partie supérieure ; - la partie inférieure comprend deux montants sensiblement verticaux reliés entre eux par une traverse inférieure du côté inférieur et munis respectivement de prolongements latéraux du côté supérieur ; la partie inférieure comprend des premières fixations solidaires des montants pour la fixation sur des longerons inférieurs de la structure du véhicule et des secondes fixations solidaires des prolongements latéraux pour la fixation sur des longerons supérieurs de la structure du véhicule ; - les prolongements latéraux contribuent à délimiter des logements pour les projecteurs du véhicule ;- The joints are spaced from each other and located at the ends of the lower part and at the ends of the upper part; - The lower part comprises two substantially vertical uprights connected to each other by a lower cross member on the lower side and respectively provided with lateral extensions on the upper side; the lower part comprises first fasteners integral with the uprights for fixing on lower longitudinal members of the vehicle structure and second fasteners integral with lateral extensions for fixing on upper longitudinal members of the vehicle structure; - the lateral extensions help to delimit housings for the vehicle headlights;
- la partie supérieure porte les projecteurs du véhicule ;- the upper part carries the vehicle headlights;
- la partie inférieure porte les projecteurs du véhicule ;- the lower part carries the headlights of the vehicle;
- les projecteurs du véhicule sont montés mobiles sur des glissières de la partie inférieure ;- the vehicle headlamps are mounted movable on slides in the lower part;
- les montants de la partie inférieure portent des glissières pour permettre un montage coulissant d'un radiateur ou d'un module de refroidissement ;- the uprights in the lower part carry slides to allow sliding mounting of a radiator or cooling module;
- la face avant comprend des moyens de verrouillage pour maintenir la partie supérieure et la partie inférieure en position rapprochée.- The front face comprises locking means to maintain the upper part and the lower part in the close position.
Dans la description qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :In the description which follows, given solely by way of example, reference is made to the appended drawings, in which:
la Figure 1 est une vue en perspective d'une face avant de véhicule automobile selon l'invention, dans laquelle la partie inférieure et la partie supérieure sont en position rapprochée ; et la Figure 2 est une vue. partielle en perspective d'un véhicule automobile équipé de la face avant de la Figure 1, dans laquelle la partie inférieure et la partie supérieure sont en position éloignée.Figure 1 is a perspective view of a front face of motor vehicle according to the invention, in which the lower part and the upper part are in close position; and Figure 2 is a view. partial perspective view of a motor vehicle equipped with the front face of FIG. 1, in which the lower part and the upper part are in the remote position.
On se réfère d'abord à la Figure 1 qui montre une face avant de véhicule automobile qui comprend un support 10 formé de deux parties, à savoir une partie inférieure 12 et une partie supérieure 14.First, reference is made to FIG. 1 which shows a front face of a motor vehicle which comprises a support 10 formed of two parts, namely a lower part 12 and an upper part 14.
La partie inférieure 12 comprend deux montants 16 sensiblement verticaux (lorsque la face avant, est montée sur un véhicule automobile) reliés entre eux, du côté inférieur, par une traverse inférieure 18. Ces deux.montants .16 sont munis chacun de deux prolongements latéraux 20, du côté supérieur. Ces prolongements latéraux ont une forme incurvée et contribuent à délimiter chacun un logement 22 pour un projecteur 24 (Figure 2). Chacun des prolongements latéraux 20 se termine par une extrémité. 26 portant une plaque de fixation 28. Les deux plaques 28 sont destinées à être fixées sur des longerons supérieurs 30 du véhicule.The lower part 12 comprises two substantially vertical uprights 16 (when the front face is mounted on a motor vehicle) connected to each other, on the lower side, by a lower cross member 18. These deux.montants .16 are each provided with two lateral extensions 20, on the upper side. These lateral extensions have a curved shape and contribute to delimiting each a housing 22 for a projector 24 (Figure 2). Each of the lateral extensions 20 ends at one end. 26 carrying a fixing plate 28. The two plates 28 are intended to be fixed on upper side members 30 of the vehicle.
Par ailleurs, chacun des montants 16 est muni, du côté extérieur, d'une plaque de fixation 32 destinée à être fixée à l'extrémité d'un longeron inférieur 34 du véhicule.Furthermore, each of the uprights 16 is provided, on the outside, with a fixing plate 32 intended to be fixed to the end of a lower spar 34 of the vehicle.
La partie supérieure 14 comprend une traverse supérieure 36 ayant deux extrémités 38 reliées par des articulations 40 aux extrémités 26 des prolongements latéraux 20. Les deux articulations 40 sont alignées suivant un axe Y-Y qui, dans la position de montage sur le. véhicule, est horizontal et transversal. La traverse 36 comprend une partie centrale 42 encadrée par deux parties latérales 44 situées respectivement au-dessus des prolongements latéraux 20 et à distance de ces derniers. Ainsi, les deux prolongements latéraux 20 et les parties latérales 44 contribuent à délimiter les emplacements 22 pour les projecteurs 24. La partie centrale 42 de la traverse supérieure 36 porte aussi une fixation 46 pour la serrure du capot 48 (Figure 2) du véhicule.The upper part 14 comprises an upper crosspiece 36 having two ends 38 connected by articulations 40 to the ends 26 of the lateral extensions 20. The two articulations 40 are aligned along an axis YY which, in the mounting position on the. vehicle, is horizontal and transverse. The cross member 36 comprises a central part 42 framed by two lateral parts 44 situated respectively above the lateral extensions 20 and at a distance from the latter. Thus, the two lateral extensions 20 and the lateral parts 44 contribute to delimiting the locations 22 for the projectors 24. The central part 42 of the upper cross member 36 also carries a fixing 46 for the lock of the hood 48 (Figure 2) of the vehicle.
La partie supérieure 14 peut ainsi pivoter par rapport à la partie inférieure 12 entre deux positions extrêmes : une position rapprochée (comme montré sur la Figure 1) en laquelle les deux parties de la face avant sont rassemblées et forment un ensemble unitaire, et une position éloignée (comme montré sur la Figure 2) en laquelle les deux parties sont éloignées l'une de l'autre.The upper part 14 can thus pivot relative to the lower part 12 between two extreme positions: a close position (as shown in Figure 1) in which the two parts of the front face are brought together and form a unitary assembly, and a position distant (as shown in Figure 2) in which the two parts are distant from each other.
Dans la position rapprochée de la Figure 1, la partie supérieure 14 est verrouillée sur la partie inférieure 12 par des moyens de verrouillage comprenant ici deux goupilles 50 du type quart de tour susceptibles de s'engager chacune dans des ouvertures 52 de la partie supérieure 14 et dans des ouvertures alignées correspondantes (non visibles sur la Figure 1) de la partie inférieure 12.In the close position of Figure 1, the upper part 14 is locked on the lower part 12 by locking means here comprising two pins 50 of the quarter turn type capable of each engaging in openings 52 of the upper part 14 and in corresponding aligned openings (not visible in Figure 1) of the lower part 12.
Dans la position éloignée représentée sur la Figure 2, la partie supérieure 14 se trouve en position relevée et facilite ainsi l'accès aux composants placés dans le compartiment moteur.In the remote position shown in Figure 2, the upper part 14 is in the raised position and thus facilitates access to the components placed in the engine compartment.
Comme on le voit sur la Figure 1, les deux montants 16 portent des glissières 54, situées en vis-à-vis, et permettant le montage coulissant d'un module d'échange de chaleur 56 (Figure 2). Ce module d'échange de chaleur constitue habituellement un module de refroidissement qui peut être constitué soit du radiateur de refroidissement du véhicule, soit d'un groupe d'echangeurs de chaleur. En ce cas, il s'agit habituellement du radiateur de refroidissement du moteur et d'un condenseur de climatisation. ,As seen in Figure 1, the two uprights 16 carry slides 54, located opposite, and allowing the sliding mounting of a heat exchange module 56 (Figure 2). This heat exchange module usually constitutes a cooling module which can consist either of the vehicle cooling radiator or of a group heat exchangers. In this case, it is usually the engine cooling radiator and an air conditioning condenser. ,
Ainsi, lorsque la partie supérieure se trouve dans la position relevée de la Figure 2, l'accès aux composants, notamment au module d'échange de chaleur 56, se trouve facilité. Le remplissage du radiateur de refroidissement est donc facilité.Thus, when the upper part is in the raised position of FIG. 2, access to the components, in particular to the heat exchange module 56, is facilitated. Filling the cooling radiator is therefore facilitated.
Dans une forme de réalisation de l'invention, comme montré à la Figure 2, les deux projecteurs 24 sont solidaires de la partie supérieure 14. Cela signifie que ces deux projecteurs sont fixés sous les parties latérales 44 de cette partie supérieure. Ainsi, la rotation selon l'axe Y-Y de la partie supérieure 14 entraîne la rotation des deux projecteurs 24, ce qui permet de libérer de l'espace pour l'accès aux fonctions d'entretien, notamment l'accès aux lampes, douilles et faisceau des projecteurs.In one embodiment of the invention, as shown in FIG. 2, the two projectors 24 are integral with the upper part 14. This means that these two projectors are fixed under the lateral parts 44 of this upper part. Thus, the rotation along the axis YY of the upper part 14 causes the rotation of the two projectors 24, which frees up space for access to maintenance functions, in particular access to lamps, sockets and spotlight beam.
Dans une variante de réalisation (non représentée), les projecteurs 24 pourraient être solidaires de la partie inférieure 12. En ce cas, il est envisageable de monter les projecteurs sur des glissières de la partie inférieure 12 pour faciliter l'accès aux lampes, douilles et faisceaux des projecteurs.In an alternative embodiment (not shown), the projectors 24 could be secured to the lower part 12. In this case, it is possible to mount the projectors on slides of the lower part 12 to facilitate access to the lamps, sockets and spotlight beams.
Ainsi, dans la position de la Figure 2, l'accès aux différents composants est facilité et, de ce fait, il n'est plus nécessaire de prévoir des volumes morts dans le compartiment moteur, notamment au niveau des projecteurs et du module de refroidissement.Thus, in the position of Figure 2, access to the various components is facilitated and, therefore, it is no longer necessary to provide dead volumes in the engine compartment, in particular at the headlights and the cooling module. .
Cela permet par conséquent de diminuer l'encombrement global des équipements et d'améliorer la compacité de l'ensemble, tout en facilitant la maintenance, l'entretien et l'accès aux composants de la face avant.This therefore reduces the overall size of the equipment and improves the compactness of the assembly, while facilitating maintenance, upkeep and access to front panel components.
Il convient aussi de souligner que, dans la position rapprochée de la Figure 1, qui constitue la position normale de la face avant, cette dernière se comporte comme un ensemble monobloc aussi résistant qu'une face avant classique réalisée en une seule partie.It should also be emphasized that, in the close position of FIG. 1, which constitutes the normal position of the front face, the latter behaves like a one-piece assembly as resistant as a conventional front face produced in a single part.
La partie inférieure 12 et la partie supérieure 14 du support sont réalisées soit en matière plastique, soit en une matière hybride métal/plastique.The lower part 12 and the upper part 14 of the support are made either of plastic material, or of a hybrid metal / plastic material.
Bien entendu, l'invention n'est pas limitée aux formes de réalisation décrites précédemment à titre d'exemple et s'étend à d'autres variantes. En particulier, il est envisageable de prévoir d'autres moyens pour réaliser le montage amovible de la partie supérieure 14 par rapport à la partie inférieure 12. Of course, the invention is not limited to the embodiments described above by way of example and extends to other variants. In particular, it is possible to envisage other means for carrying out the removable mounting of the upper part 14 relative to the lower part 12.
