Description

L'invention s'applique au domaine de l'éclairage et de la signalisation des véhicules automobiles.The invention applies to the field of lighting and signaling of motor vehicles.

Plus particulièrement, l'invention concerne un boîtier spécifique pour un module de signalisation tel que des feux de jour ou feux diurnes (dits DRL pour « Daytime Running Lights ») destinés à équiper les véhicules automobiles ainsi qu'un véhicule automobile équipé dudit module.More particularly, the invention relates to a specific housing for a signaling module such as daytime running lights (known as DRLs for “ Daytime Running Lights ”) intended to equip motor vehicles as well as a motor vehicle equipped with said module.

De manière traditionnelle, les véhicules automobiles sont équipés, sur leur face avant, de modules d'éclairage (projecteur, codes, feux de route) et de modules de signalisation (feux de jour dits « DRL », identificateur de direction, clignotants, ...). Chaque module comprend un système électronique (par exemple, une carte de circuit imprimé, PCB) pilotant une ou plusieurs sources d'éclairage sous forme de lampes (halogènes, xénon, LED, ...) associées à un système optique (lentille, réflecteur ...).Traditionally, motor vehicles are equipped, on their front, with lighting modules (headlight, codes, high beam) and signaling modules (daytime running lights called “DRL”, direction identifier, indicators, etc.). ..). Each module includes an electronic system (for example, a printed circuit board, PCB) controlling one or more lighting sources in the form of lamps (halogen, xenon, LED, etc.) associated with an optical system (lens, reflector ...).

Les composants électroniques et optiques de chaque module sont encapsulés dans des boîtiers obturés de façon étanche par une glace qui est, soit commune à plusieurs boîtiers, soit indépendante pour chaque boîtier, et qui est fixée généralement par soudure.The electronic and optical components of each module are encapsulated in boxes sealed in a sealed manner by a glass which is either common to several boxes or independent for each box, and which is generally fixed by welding.

Aujourd'hui sur certains véhicules, le boîtier du module de signalisation et, notamment, celui du module de signalisation de jour (DRL) est lui-même logé dans un boîtier plus important renfermant également des modules de feux de route ou d'éclairage (feux de route, de croisement, ...) et, notamment, à l'intérieur d'un boîtier de projecteur qui est obturé par une glace frontale.Today on certain vehicles, the housing of the signaling module and, in particular, that of the daytime signaling module (DRL) is itself housed in a larger housing also containing high beam or lighting modules ( high beam, low beam, etc.) and, in particular, inside a headlight housing which is closed by a front glass.

Un tel module de signalisation de jour, qui intègre à la fois une source d'éclairage (lampes Leds, ...) et un système électronique associé (PCB), a globalement un profil plat et uniforme pour assurer une homogénéité du flux lumineux. Ce module est monté à l'intérieur de son propre boîtier avant la fermeture définitive de ce dernier et sa fixation dans le boîtier de projecteur.Such a daytime signaling module, which integrates both a lighting source (Led lamps, etc.) and an associated electronic system (PCB), generally has a flat and uniform profile to ensure homogeneity of the luminous flux. This module is mounted inside its own housing before the latter is definitively closed and fixed in the projector housing.

Le boîtier de ce module de signalisation étant généralement réalisé sous forme monobloc ou à partir de pièces assemblées par vissage, collage ou rivetage, en cas d'usure ou de défaut de fonctionnement, le module doit être remplacé intégralement et il est alors nécessaire de procéder à un changement complet du boîtier ou à son ouverture forcée.The housing of this signaling module being generally made in a single piece or from parts assembled by screwing, gluing or riveting, in the event of wear or malfunction, the module must be completely replaced and it is then necessary to proceed to a complete change of the case or its forced opening.

Cependant, ces opérations ont des coûts significatifs et sont, en outre, difficiles et délicates à mettre en oeuvre et peuvent même, parfois, conduire à un endommagement voire une destruction du boîtier.However, these operations have significant costs and are, moreover, difficult and delicate to implement and can even, sometimes, lead to damage or even destruction of the housing.

Par ailleurs, les boîtiers actuels renfermant ces modules de signalisation sont soumis à des vibrations qui se propagent au module interne en générant ainsi des perturbations problématiques du signal lumineux.Furthermore, the current boxes containing these signaling modules are subject to vibrations which propagate to the internal module, thus generating problematic disturbances of the light signal.

Dans ce contexte, l'invention vise à apporter une solution technique permettant d'assurer l'intégration d'un module de signalisation interchangeable dans un boîtier aisément démontable dont le profil peut rester inchangé et sans compromettre la fiabilité de l'assemblage au boîtier de projecteur dans lequel il est toujours destiné à être logé. US2011/0205747 divulgue un boîtier de support selon le préambule de la revendication 1.In this context, the invention aims to provide a technical solution making it possible to ensure the integration of an interchangeable signaling module in an easily removable housing whose profile can remain unchanged and without compromising the reliability of the assembly to the housing. projector in which it is always intended to be housed. US2011/0205747 discloses a support housing according to the preamble of claim 1.

Ce but est atteint au moyen d'un boîtier de support pour un module de signalisation de véhicule automobile comprenant une source d'éclairage et un système électronique associé, caractérisé en ce que ledit boîtier comprend une coque inférieure et une coque supérieure délimitant entre elles un compartiment ouvert à l'avant pour permettre l'introduction du module, ladite coque inférieure et ladite coque supérieure portant, à l'arrière, des organes de guidage, des organes de liaison et des organes de verrouillage coopérant mutuellement pour assurer l'assemblage des deux coques.This goal is achieved by means of a support housing for a motor vehicle signaling module comprising a lighting source and an associated electronic system, characterized in that said housing comprises a lower shell and an upper shell delimiting between them a compartment open at the front to allow the introduction of the module, said lower shell and said upper shell carrying, at the rear, guide members, connecting members and locking members cooperating mutually to ensure the assembly of the two hulls.

Selon l'invention, les organes de guidage comprennent, sur la coque inférieure, une gorge périphérique destinée à recevoir le bord d'extrémité de la coque supérieure en épousant ses contours.According to the invention, the guide members comprise, on the lower shell, a peripheral groove intended to receive the end edge of the upper shell by matching its contours.

Selon l'invention, la gorge périphérique présente, à l'une de ses extrémités longitudinales, une portion sensiblement verticale et, à son autre extrémité, une portion tronquée offrant une liberté de débattement à la coque supérieure lors de l'assemblage.According to the invention, the peripheral groove has, at one of its longitudinal ends, a substantially vertical portion and, at its other end, a truncated portion offering freedom of movement to the upper shell during assembly.

Selon une autre caractéristique, les organes de guidage comprennent, en outre, des dents faisant saillie sur le fond de la coque inférieure à proximité de ladite gorge périphérique et dont le bord arrière biseauté coopère avec le bord d'extrémité de la coque supérieure.According to another characteristic, the guide members further comprise teeth projecting from the bottom of the lower shell near said peripheral groove and whose beveled rear edge cooperates with the end edge of the upper shell.

Avantageusement, le bord d'extrémité de la coque supérieure est pourvu localement de bossages destinés à assurer un serrage dans la gorge périphérique de la coque inférieure lors de l'assemblage.Advantageously, the end edge of the upper shell is locally provided with bosses intended to ensure tightening in the peripheral groove of the lower shell during assembly.

Selon un mode de réalisation spécifique, les organes de liaison comprennent au moins deux protubérances sensiblement tronconiques portées par le fond de la coque inférieure et destinées à s'engager, lors de l'assemblage, dans deux cavités de profil complémentaire ménagées en regard sur la coque supérieure en vue d'assurer son centrage.According to a specific embodiment, the connecting members comprise at least two substantially frustoconical protuberances carried by the bottom of the lower shell and intended to engage, during assembly, in two cavities of complementary profile provided facing the upper hull to ensure its centering.

De préférence, ces protubérances sont pourvues de nervures verticales effilées assurant une mise sous contraintes de la coque supérieure lors de son assemblage sur la coque inférieure.Preferably, these protuberances are provided with tapered vertical ribs ensuring that the upper shell is placed under stress during its assembly on the lower shell.

Selon un autre mode ce réalisation du boîtier de l'invention, les organes de verrouillage comprennent au moins deux ergots solidaires du bord d'extrémité de la coque inférieure et destinées à s'encliqueter de manière élastique dans deux orifices complémentaires ménagés en regard dans des pattes solidaires du bord d'extrémité de la coque supérieure.According to another embodiment of the housing of the invention, the locking members comprise at least two lugs secured to the end edge of the lower shell and intended to snap into place elastically in two complementary orifices provided opposite in legs secured to the end edge of the upper shell.

Selon encore une autre caractéristique, les bords d'extrémité de la coque supérieure et de la coque inférieure sont chanfreinés pour faciliter leur positionnement relatif lors de l'assemblage.According to yet another characteristic, the end edges of the upper shell and the lower shell are chamfered to facilitate their relative positioning during assembly.

Un autre objet de l'invention est un véhicule automobile équipé d'un module de signalisation (DRL) logé dans un boîtier présentant les caractéristiques définies ci-dessus.Another object of the invention is a motor vehicle equipped with a signaling module (DRL) housed in a housing having the characteristics defined above.

Le boîtier de l'invention trouve son application pour une intégration du module de signalisation DRL, tant dans un système d'éclairage à lampes LED qu'à lampes halogène. Ce boîtier est fabriqué de façon indépendante du boîtier de projecteur à l'intérieur duquel il est destiné à être logé.The housing of the invention finds its application for integration of the DRL signaling module, both in a lighting system with LED lamps and halogen lamps. This housing is manufactured independently of the projector housing inside which it is intended to be housed.

Une application spécifique de ce boîtier se trouve dans le conditionnement d'un module de signalisation DRL interchangeable (du type « Flat guide ») qui peut être aisément introduit ou sorti du boîtier après la séparation des deux coques, respectivement inférieure et supérieure.A specific application of this housing is in the packaging of an interchangeable DRL signaling module (of the “Flat guide” type) which can be easily inserted or removed from the housing after the separation of the two shells, respectively lower and upper.

La maintenance du module de signalisation est grandement facilitée puisque le remplacement de ce module peut être effectué manuellement, sans outillage, en ayant au préalable démonté le boîtier par ouverture des organes de verrouillage des coques.Maintenance of the signaling module is greatly facilitated since the replacement of this module can be carried out manually, without tools, by having first dismantled the housing by opening the locking members of the shells.

Par conséquent, l'invention offre un gain économique et une simplification du procédé d'assemblage.Consequently, the invention offers an economic gain and a simplification of the assembly process.

It is explicitly planned that different modes can be proposed and combined to offer others.

L'invention concerne le domaine de l'éclairage et de la signalisation des véhicules automobiles.The invention relates to the field of lighting and signaling of motor vehicles.

Plus précisément, l'invention concerne un boîtier B de module de signalisation de feux de jour ou feux diurnes (DRL). Ce module DRL comprend, de manière traditionnelle, un système d'éclairage constitué d'une source lumineuse (par exemple des lampes Leds) couplée à un circuit électronique (par exemple PSB).More specifically, the invention relates to a housing B for a daytime running light or daytime running light (DRL) signaling module. This DRL module comprises, in a traditional manner, a lighting system consisting of a light source (for example LED lamps) coupled to an electronic circuit (for example PSB).

Le module de signalisation DRL est enfermé à l'intérieur du boîtier 1 entre une coque inférieure 1 et une coque supérieure 2, comme illustré par la figure 1A. A cet effet, la coque inférieure 1 et la coque supérieure 2 délimitent entre elles un compartiment destiné à contenir le module DRL qui est ouvert à l'avant pour assurer la diffusion du signal lumineux et permettre l'introduction ou l'extraction de ce module.The DRL signaling module is enclosed inside the housing 1 between a lower shell 1 and an upper shell 2, as illustrated by the Figure 1A . For this purpose, the lower shell 1 and the upper shell 2 define between them a compartment intended to contain the DRL module which is open at the front to ensure the diffusion of the light signal and allow the introduction or extraction of this module .

Ce module DRL est généralement réalisé sous forme d'un bloc compact, plat et homogène du type « Flat guide », intégrant tous les composants optiques et électroniques nécessaires qui est livré prêt au montage dans le boîtier B.This DRL module is generally produced in the form of a compact, flat and homogeneous block of the “Flat guide” type, integrating all the necessary optical and electronic components which is delivered ready for assembly in box B.

Selon l'invention, la coque inférieure 1 et la coque supérieure 2 portent des organes de guidage, des organes de liaison et des organes de verrouillage coopérant mutuellement pour assurer l'assemblage des deux coques et la fermeture du boîtier en emprisonnant le module de signalisation DRL, comme illustré par la figure 1B. Ces organes sont déportés à l'arrière du boîtier B du fait que sa face avant est ouverte.According to the invention, the lower shell 1 and the upper shell 2 carry guide members, connecting members and locking members cooperating mutually to ensure the assembly of the two shells and the closing of the housing by trapping the signaling module DRL, as shown in the Figure 1B . These bodies are offset to the rear of housing B because its front face is open.

Toutefois, il sera possible d'inverser la disposition de tous ou partie des organes de guidage, des organes de liaison et des organes de verrouillage, décrits en détail ci-après, entre la coque inférieure 1 et la coque supérieure 2 sans sortir du cadre de l'invention.However, it will be possible to reverse the arrangement of all or part of the guide members, the connecting members and the locking members, described in detail below, between the lower shell 1 and the upper shell 2 without leaving the frame of the invention.

Selon l'invention, les organes de guidage comprennent, sur la coque inférieure 1, une gorge périphérique 10 destinée à recevoir le bord d'extrémité arrière 2a de la coque supérieure 2 en épousant ses contours. A cet effet, le profil du bord d'extrémité arrière de la coque supérieure 2 est complémentaire de la section en U de la gorge 10.According to the invention, the guide members comprise, on the lower shell 1, a peripheral groove 10 intended to receive the rear end edge 2a of the upper shell 2 by matching its contours. For this purpose, the profile of the rear end edge of the upper shell 2 is complementary to the U-shaped section of the groove 10.

La gorge périphérique 10 présente, à l'une de ses extrémités longitudinales, une portion sensiblement verticale 10a et, à son autre extrémité, une portion tronquée 10b offrant, lors de son assemblage à la coque supérieure 2, une liberté de débattement en translation en évitant un hyper-statisme, comme illustré par les figures 2A, 3A et 5A.The peripheral groove 10 has, at one of its longitudinal ends, a substantially vertical portion 10a and, at its other end, a truncated portion 10b offering, during its assembly to the upper shell 2, freedom of movement in translation in avoiding hyper-statism, as illustrated by the figures 2A , 3A And 5A .

En outre, le bord d'extrémité 2a de la coque supérieure 2 et celui 1a de la coque inférieure 1 sont chanfreinés pour parfaire leur positionnement relatif à la fois verticalement et horizontalement lors de l'assemblage et avant le verrouillage.In addition, the end edge 2a of the upper shell 2 and that 1a of the lower shell 1 are chamfered to perfect their relative positioning both vertically and horizontally during assembly and before locking.

La coque inférieure 1 comprend, en outre, des organes de guidage complémentaires constitués de dents 11 (quatre dents dans le mode de réalisation de la figure 2A) qui font saillie sur le fond de la coque inférieure à proximité de la gorge périphérique 10. Le bord arrière 11a des dents 11 est biseauté, comme illustré notamment par la figure 3C, et vient au contact du bord d'extrémité 2a de la coque supérieure 2 pour l'orienter vers la gorge 10 et faciliter ainsi l'assemblage avec la coque inférieure 1.The lower shell 1 further comprises complementary guide members consisting of teeth 11 (four teeth in the embodiment of the Figure 2A ) which project from the bottom of the lower shell near the peripheral groove 10. The rear edge 11a of the teeth 11 is beveled, as illustrated in particular by the Figure 3C , and comes into contact with the end edge 2a of the upper shell 2 to orient it towards the groove 10 and thus facilitate assembly with the lower shell 1.

Le bord d'extrémité 2a de la coque supérieure 2 est, en outre, pourvu localement d'une série de bossages 21, représentés sur la figure 2B et 4A. En effet, compte tenu de la longueur relativement importante du boîtier B, ces bossages 21 permettent d'assurer un contact mutuel avec serrage entre les deux coques 1, 2 dans la gorge périphérique 10 lors de l'assemblage et de garantir un emboîtement optimal.The end edge 2a of the upper shell 2 is, in addition, locally provided with a series of bosses 21, shown on the Figure 2B And 4A . Indeed, taking into account the relatively long length of the housing B, these bosses 21 make it possible to ensure mutual contact with tightening between the two shells 1, 2 in the peripheral groove 10 during assembly and to guarantee optimal interlocking.

Les organes de liaison entre les deux coques 1, 2 comprennent au moins deux protubérances ou colonnes 12 sensiblement tronconiques (figures 3A et 3B) portées par le fond de la coque inférieure 1. Les protubérances 12 sont destinées à s'engager, lors de l'assemblage du boîtier B, dans deux cavités 22 de profil complémentaire ménagées en regard sur la coque supérieure 2 en vue d'assurer son centrage, comme illustré par les figures 3A, 3B et 4A. Les cavités 22 sont ménagées ici dans des plots 24 en saillie et en forme de dômes portés par le fond de la coque supérieure 2.The connecting members between the two shells 1, 2 comprise at least two substantially frustoconical protuberances or columns 12 ( Figures 3A and 3B ) carried by the bottom of the lower shell 1. The protuberances 12 are intended to engage, during the assembly of the housing B, in two cavities 22 of complementary profile provided facing each other on the upper shell 2 in order to ensure its centering, as illustrated by the Figures 3A, 3B And 4A . The cavities 22 are provided here in projecting studs 24 in the shape of domes carried by the bottom of the upper shell 2.

Chaque protubérance 12 est, de préférence, pourvue de nervures verticales effilées 12a, ici au nombre de trois (respectivement une nervure sur une première face de la protubérance 12 et deux nervures sur la face opposée). Ces nervures 12a assurent une mise sous contraintes de la coque supérieure 2 lorsque, en phase finale d'assemblage, les cavités 22 viennent coiffer en force les protubérances 12 de la coque inférieure 1, comme illustré par la figure 4B.Each protuberance 12 is preferably provided with tapered vertical ribs 12a, here three in number (respectively one rib on a first face of the protuberance 12 and two ribs on the opposite face). These ribs 12a ensure that the upper shell 2 is placed under stress when, in the final assembly phase, the cavities 22 forcefully cover the protuberances 12 of the lower shell 1, as illustrated by the Figure 4B .

Pour faciliter l'engagement des protubérances 12 dans les cavités 22, ces dernières présentent une ouverture évasée 22a, comme illustré en coupe par la figure 4B. La mise sous contrainte des coques 1, 2 une fois assemblées l'une à l'autre permet d'éviter la propagation des vibrations et protège ainsi le fonctionnement du module DRL.To facilitate the engagement of the protuberances 12 in the cavities 22, the latter have a flared opening 22a, as illustrated in section by the Figure 4B . Placing the shells 1, 2 under stress once assembled together makes it possible to avoid the propagation of vibrations and thus protects the operation of the DRL module.

Les organes de verrouillage comprennent au moins deux ergots 13 (visibles notamment sur les figures 1A, 1B et 3A) solidaires du bord d'extrémité 1a de la coque inférieure 1 et destinées à s'encliqueter, de manière élastique et donc réversible, dans deux orifices complémentaires 20 ménagés en regard dans des pattes 23 solidaires du bord d'extrémité 2a de la coque supérieure 2, comme illustré par les figures 5A, 5B.The locking members comprise at least two lugs 13 (visible in particular on the figures 1A, 1B And 3A ) secured to the end edge 1a of the lower shell 1 and intended to snap into place, elastically and therefore reversibly, in two complementary orifices 20 provided opposite in lugs 23 secured to the end edge 2a of the upper shell 2, as illustrated by figures 5A , 5B .

Les ergots 13 sont portés par des pattes 14 dont les dimensions sont sensiblement identiques à celles des pattes 23. La face externe des ergots 13 est inclinée vers le bas pour faciliter le coulissement des pattes 23 et la mise en regard avec les orifices 20.The lugs 13 are carried by lugs 14 whose dimensions are substantially identical to those of the lugs 23. The external face of the lugs 13 is inclined downwards to facilitate the sliding of the lugs 23 and their alignment with the orifices 20.

Le déverrouillage des deux coques 1, 2 et l'ouverture du boîtier B peut être effectué aisément en appuyant manuellement sur la face externe des ergots 13 pour les libérer des pattes 23 puis en exerçant une traction sur la coque supérieure 2 afin de séparer les deux coques. L'accès au compartiment intérieur dans lequel se trouve le module DRL devient alors possible.The unlocking of the two shells 1, 2 and the opening of the housing B can be easily carried out by manually pressing on the external face of the lugs 13 to release them from the tabs 23 then by exerting traction on the upper shell 2 in order to separate the two hulls. Access to the interior compartment in which the DRL module is located then becomes possible.
