Description

La présente invention concerne d'une façon générale les dispositifs de ventilation pour appareils d'éclairage ou de signalisation pour véhicules automobiles.The present invention relates generally to ventilation devices for lighting or signaling for motor vehicles.

Une préoccuppation constante lors de la conception de ces dispositifs de ventilation est d'assurer une ventilation ou une aération satisfaisante de l'espace intérieur du boítier ou du socle de l'appareil, tout en évitant le plus efficacement possible la pénétration d'eau, de boue, de poussière, ... dans cet espace intérieur.A constant concern when designing these ventilation devices is to provide ventilation or satisfactory ventilation of the interior space of the housing or base of the device, while avoiding the most effectively the penetration of water, mud, dust, ... in this interior space.

La difficulté est aujourd'hui d'autant plus grande qu'il faut éviter toute pénétration d'eau en présence d'un jet de lavage sous haute pression par exemple du compartiment moteur du véhicule, auquel les boítiers de projecteurs avant sont exposés.The difficulty is all the greater today that penetration of water must be avoided in the presence of a high pressure washing jet for example engine compartment of the vehicle, to which the headlights are exposed.

Les documents FR-A-2 654 048, FR-A-2 183 934, FR-A-2 660 413 et US-A-4 739 458 réflètent notamment l'état de la technique. Un dispositif tel que défini dans le préambule de la revendication 1 est connu de FR-A-2 626 060.Documents FR-A-2 654 048, FR-A-2 183 934, FR-A-2 660,413 and US-A-4,739,458 reflect in particular the state of the technical. A system as defined in the preamble to the claim 1 is known from FR-A-2 626 060.

On connaít également par US-A-5 010 453 un dispositif qui présente cependant une efficacité limitée de par le caractère peu sinueux du trajet d'air. En outre, la fixation du bouchon est sommaire, et celui-ci peut, dans le temps, se séparer accidentellement du boítier.We also know from US-A-5,010,453 a device which however has an efficiency limited due to the low curvature of the air path. In besides, the fixing of the cap is sketchy, and this one may, over time, accidentally separate from the housing.

La présente invention vise à proposer un nouveau dispositif de ventilation qui, grâce à des moyens simples, économiques et augmentant peu l'encombrement global, forme un trajet sinueux améliorant l'effet de barrière aux liquides, et dans lequel la fixation du bouchon soit améliorée.The present invention aims to propose a new ventilation device which, thanks to simple means, economical and slightly increasing the overall size, a winding path improving the barrier effect to liquids, and in which the fixing of the cap is improved.

Un autre objet de l'invention est de proposer un dispositif facile à monter, et qui puisse aisément recevoir si nécessaire un filtre mousse.Another object of the invention is to provide a device easy to assemble, and which can easily receive if necessary a foam filter.

La présente invention propose à cet effet un appareil d'éclairage ou de signalisation pour véhicule automobile tel que défini dans la revendication 1. The present invention provides for this purpose an apparatus lighting or signaling for motor vehicle such as defined in claim 1.

Des aspects préférés, mais non limitatifs, de l'appareil selon l'invention sont définis dans les sous-revendications.Preferred, but not limiting, aspects of the apparatus according to the invention are defined in the subclaims.

D'autres aspects, buts et avantages de la présente invention apparaítront mieux à la lecture de la description détaillée suivante d'une forme de réalisation préférée de celle-ci, donnée à titre d'exemple non limitatif et faite en référence aux dessins annexés, sur lequel :

  • la figure 5 est une vue en élévation de face de la partie de boítier et du capot, assemblés, et
  • la figure 6 est une vue en coupe verticale transversale de l'assemblage de la figure 5.
    • Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of a preferred embodiment thereof, given by way of non-limiting example and made with reference to the accompanying drawings, on which :

    • En référence au dessin, la référence 100 sur les figures 1, 2, 5 et 6 désigne une partie d'une paroi, par exemple postérieure, d'un boítier de projecteur selon la présente invention.With reference to the drawing, the reference 100 on the Figures 1, 2, 5 and 6 denote part of a wall, for rear example, of a projector housing according to the present invention.

    A partir de cette paroi 100 s'étend, dans un contour rectangulaire à coins arrondis, un jeu de cloisons comprenant :

    • une cloison supérieure extérieure 102 généralement horizontale, en saillie vers l'extérieur (vers la droite sur la figure 2), sur une première distance, à partir de la paroi 100;
    • une cloison supérieure intérieure 104 dans le prolongement de la cloison 102 et en saillie dans l'espace intérieur du boítier de projecteur (vers la gauche sur la figure 2);
    • deux cloisons verticales latérales 106a et 106b s'étendant vers le bas à partir des cloisons 102 et 104,
         une première cloison intermédiaire généralement horizontale, s'étendant entre les cloisons latérales 106a, 106b et comportant deux parties de bord 108a, 108b de section en forme générale de "L" s'étendant sur toute l'étendue des cloisons 102, 104 et séparées par une partie centrale 110, plus courte, se terminant du côté extérieur en retrait par rapport aux parties de bord 108a, 108b;
    • une cloison inférieure 118 réunissant la base des cloisons latérales 106a, 106b et ayant approximativement la même étendue vers l'extérieur que la partie 110 de la cloison intermédiaire;
    • deux murets rentrants 114a, 114b s'étendant avec un profil sensiblement en quart de cercle vers l'intérieur à partir des cloisons latérales, au-dessous des parties 108a, 108b de la cloison intermédiaire;
    • une cloison faciale intérieure 120 s'étendant entre les bords intérieurs des cloisons supérieure, intermédiaire, inférieure et latérales en laissant entre les cloisons supérieure et intermédiaire une ouverture 1201 sensiblement semi-circulaire;
    • deux cloisons faciales extérieures 122a, 122b s'étendant entre les murets 114a, 114b et la cloison inférieure 118 en laissant entre elles une ouverture centrale 124 de largeur prédéterminée.
    From this wall 100 extends, in a rectangular contour with rounded corners, a set of partitions comprising:
    • a generally horizontal external upper partition 102 projecting outwards (to the right in FIG. 2), over a first distance, from the wall 100;
    • an interior upper partition 104 in the extension of the partition 102 and projecting into the interior space of the projector housing (to the left in FIG. 2);
    • two vertical side partitions 106a and 106b extending downwards from the partitions 102 and 104,
      a first generally horizontal intermediate partition, extending between the lateral partitions 106a, 106b and comprising two edge portions 108a, 108b of section in the general shape of "L" extending over the entire extent of the partitions 102, 104 and separated by a central part 110, shorter, ending on the outer side set back relative to the edge parts 108a, 108b;
    • a lower partition 118 joining the base of the lateral partitions 106a, 106b and having approximately the same extension towards the outside as the part 110 of the intermediate partition;
    • two re-entrant walls 114a, 114b extending with a profile substantially in a quarter circle inwards from the side partitions, below the parts 108a, 108b of the intermediate partition;
    • an interior facial partition 120 extending between the interior edges of the upper, intermediate, lower and lateral partitions, leaving between the upper and intermediate partitions an opening 1201 substantially semi-circular;
    • two external facial partitions 122a, 122b extending between the walls 114a, 114b and the lower partition 118 leaving between them a central opening 124 of predetermined width.

    Ces différents aménagements sont de préférence venus de moulage lors de la fabrication du boítier ou socle de l'appareil d'éclairage ou de signalisation.These various arrangements preferably came from molding during the manufacture of the housing or base the lighting or signaling device.

    Le dispositif de ventilation selon l'invention comprend également un bouchon illustré en détail sur les figures 3 et 4.The ventilation device according to the invention comprises also a plug illustrated in detail in FIGS. 3 and 4.

    Ce bouchon, globalement désigné par la référence 200, comporte :

    • une cloison supérieure 202, une cloison inférieure 206 et deux cloisons latérales 212a, 212b dont les contours intérieurs correspondent sensiblement aux contours extérieurs des cloisons 102, 118, 106a et 106b;
    • une cloison faciale 204 réunissant les cloisons susmentionnées et pleine sur toute son étendue;
    • deux pattes flexibles 210a, 210b s'étendant vers l'intérieur à partir de la cloison 204, présentant des profils respectifs en arcs de cercle concentriques et comportant à leurs extrémités libres des dents d'accrochage 2101a, 2101b de section généralement triangulaire, en saillie vers l'extérieur; on observe que ces pattes définissent entre elles un logement généralement cylindrique, dans lequel peut être logée de façon optionnelle une pièce en mousse élastique formant filtre, désignée par la référence 300; il s'agit de préférence de mousse de polyuréthanne réticulé ayant environ 7 pores/cm2 et une masse volumique d'environ 20 à 25 kg/m3.
    • deux murets rentrants en quart de cercle 214a, 214b dont la face supérieure est apte à épouser la face inférieure des murets respectifs 114a, 114b du boítier, ces murets s'étendant à partir de la paroi 204 sur une partie seulement de la profondeur du bouchon et étant réunis par une cloison intermédiaire horizontale 208 plus saillante, ayant la même étendue horizontale que les cloisons supérieure, inférieure et latérales; on observera que la largeur de la cloison 208 est sensiblement égale à la largeur horizontale de l'ouverture 124 des aménagements du boítier;
    • deux ouvertures 216a, 216b formées en vis-à-vis dans les parois latérales 212a, 212b au-dessous des murets 214a, 214b et ayant horizontalement sensiblement la même étendue que les murets 214a, 214b.
    This cap, generally designated by the reference 200, comprises:
    • an upper partition 202, a lower partition 206 and two lateral partitions 212a, 212b, the internal contours of which correspond substantially to the external contours of the partitions 102, 118, 106a and 106b;
    • a facial partition 204 joining the above-mentioned partitions and full over its entire extent;
    • two flexible tabs 210a, 210b extending inwards from the partition 204, having respective profiles in concentric arcs of circle and having at their free ends hooking teeth 2101a, 2101b of generally triangular section, projecting outwards; it is observed that these tabs define between them a generally cylindrical housing, in which can optionally be accommodated a piece of elastic foam forming a filter, designated by the reference 300; it is preferably crosslinked polyurethane foam having about 7 pores / cm 2 and a density of about 20 to 25 kg / m 3 .
    • two re-entrant walls in a quarter of a circle 214a, 214b, the upper face of which is capable of matching the lower face of the respective low walls 114a, 114b of the housing, these low walls extending from the wall 204 over only part of the depth of the plug and being joined by a more prominent horizontal intermediate partition 208, having the same horizontal extent as the upper, lower and lateral partitions; it will be observed that the width of the partition 208 is substantially equal to the horizontal width of the opening 124 of the housing arrangements;
    • two openings 216a, 216b formed vis-à-vis in the side walls 212a, 212b below the walls 214a, 214b and having horizontally substantially the same extent as the walls 214a, 214b.

    Le montage du bouchon sur le boítier s'effectue en plaçant tout d'abord, éventuellement, le filtre mousse 300 entre les pattes flexibles 210a, 210b et en appui contre la face intérieure de la cloison 204, comme illustré sur la figure 3, et en effectuant une translation horizontale du bouchon pour engager ses cloisons supérieure, inférieure et latérale autour des cloisons homologues du boítier et pour engager également les pattes 210a, 210b dans l'ouverture 1201 formée dans le boítier. Lorsque les dents 2101a, 2101b ont franchi les bords de cette dernière ouverture, avec une légère déformation élastique vers l'intérieur, elles s'écartent à nouveau et viennent assurer un accrochage en arrière de la cloison faciale 120, pour ainsi assurer un montage par encliquetage, la position de butée étant définie par la venue en appui des bords libres des cloisons extérieures du bouchon contre la paroi 100 du boítier.The mounting of the cap on the housing is carried out in first of all, possibly placing the foam filter 300 between the flexible legs 210a, 210b and bearing against the inside face of partition 204, as illustrated on Figure 3, and by performing a horizontal translation of the plug to engage its upper, lower and side around the homologous partitions of the case and for also engage the tabs 210a, 210b in the opening 1201 formed in the housing. When teeth 2101a, 2101b have crossed the edges of this last opening, with a slight elastic deformation towards the inside, they move away again and come to ensure a hooking in back of the face wall 120, thereby ensuring snap-in mounting, the stop position being defined by the support of the free edges of the partitions outside of the plug against the wall 100 of the housing.

    Les figures 5 et 6 représentent le dispositif de ventilation après montage. Il comporte :

    • dans sa région inférieure, un aménagement de communication avec l'extérieur en "T" à plat, cet aménagement étant défini par les deux ouvertures 216a, 216b, par l'espace existant entre la cloison 208 du bouchon et la cloison inférieure 118 du boítier, et enfin par la réduction de largeur assurée par les cloisons 122a, 122b du boítier;
    • une chicane à deux changements de direction, particulièrement bien visible sur la figure 6, un premier tronçon T1, inférieur (appartenant à la configuration en "T" précitée), étant défini entre les cloisons 118 et 208, un deuxième tronçon T2, intermédiaire, étant défini entre les cloisons 208 et 110, et un troisième tronçon T3, supérieur, étant défini entre les cloisons 110 et 102 et au travers de l'espace entre les deux pattes 210a, 210b du bouchon. Ce troisième tronçon comporte éventuellement le filtre en mousse 300, qui est alors un point de passage obligé immédiatement au-dessus de l'ouverture assurant la transition entre les deuxième et troisième tronçons et définie par les parties de cloisons 108a, 108b et 110 du boítier et par la cloison faciale 204 du bouchon.
    Figures 5 and 6 show the ventilation device after mounting. It comprises :
    • in its lower region, an arrangement for communication with the exterior in a flat "T" shape, this arrangement being defined by the two openings 216a, 216b, by the space existing between the partition 208 of the plug and the lower partition 118 of the housing , and finally by the reduction in width provided by the partitions 122a, 122b of the housing;
    • a baffle with two changes of direction, particularly clearly visible in FIG. 6, a first lower section T1 (belonging to the above-mentioned "T" configuration), being defined between the partitions 118 and 208, a second intermediate section T2, being defined between the partitions 208 and 110, and a third, upper section T3, being defined between the partitions 110 and 102 and through the space between the two tabs 210a, 210b of the plug. This third section optionally includes the foam filter 300, which is then a forced passage point immediately above the opening ensuring the transition between the second and third sections and defined by the parts of partitions 108a, 108b and 110 of the housing. and by the facial partition 204 of the plug.

    On observera que le passage assurant la transition entre les premier et deuxième tronçons T1, T2 est délimité par les murets rentrants 114a, 114b, par l'extrémité libre de la cloison 208 du bouchon et par la paroi 120 des aménagements du boítier.We will observe that the passage ensuring the transition between the first and second sections T1, T2 is delimited by the re-entrant walls 114a, 114b, by the free end of the partition 208 of the plug and through the wall 120 of housing arrangements.

    Enfin le dispositif de ventilation s'ouvre sur l'espace intérieur du boítier ou socle, à partir de la région du filtre 300, à travers l'ouverture 1201 partiellement occupée par les pattes 210a, 210b.Finally the ventilation device opens onto the space inside the housing or base, from the region of filter 300, through opening 1201 partially occupied by the legs 210a, 210b.

    On obtient ainsi un dispositif de ventilation présentant de nombreux avantages :

    • tout d'abord, lorsque un filtre mousse tel que décrit plus haut est prévu, on assure non seulement un filtrage de l'air mais également, par le jeu des pertes de charge, une limitation de l'entrée d'humidité au sein de l'appareil d'éclairage ou de signalisation; les phénomènes indésirables de condensation au niveau de la glace ou voyant de l'appareil sont donc minimisés; en outre, la présence d'une double entrée d'air en "T" permet également de limiter les entrées de vapeur issue du compartiment moteur du véhicule;
    • en outre, la même partie en "T" permet de limiter considérablement les risques d'entrée d'eau dans l'appareil d'éclairage ou de signalisation, car une grande proportion du débit d'eau d'un jet heurtant le dispositif de ventilation traverse les deux ouvertures 216a, 216b, sans remonter dans les chicanes; ces dernières permettent quant à elles de "casser" la pression du jet lors d'un arrosage avec jet sous forte pression, et d'absorber, avant qu'il ne retombe par gravité, le volume d'eau qui ne peut être éliminé par la double entrée; des essais ont démontré une bonne résistance à des jets d'eau sous une pression d'environ 4 bars;
    • la "respiration" de l'appareil d'éclairage ou de signalisation, c'est-à-dire les états successifs de dépression/surpression apparaissant en utilisation ou lors des alumages/extinctions successifs, entraíne une circulation forcée d'air vers l'intérieur de l'appareil, qui est susceptible d'y entraíner des poussières; ce phénomène est fortement limité d'une part par la présence d'une double entrée d'air, et d'autre part par la présence éventuelle du filtre 300 qui, en créant une perte de charge, diminue l'appel d'air;
    This gives a ventilation device with many advantages:
    • first of all, when a foam filter as described above is provided, it not only ensures air filtering but also, through the play of pressure drops, a limitation of the entry of humidity within lighting or signaling apparatus; the undesirable phenomena of condensation on the glass or sight glass of the device are therefore minimized; in addition, the presence of a double "T" air inlet also limits the entry of steam from the vehicle engine compartment;
    • in addition, the same "T" part makes it possible to considerably limit the risks of water entering the lighting or signaling apparatus, since a large proportion of the water flow of a jet striking the ventilation passes through the two openings 216a, 216b, without rising into the baffles; the latter make it possible to "break" the pressure of the jet when watering with a jet under high pressure, and to absorb, before it falls by gravity, the volume of water which cannot be eliminated by the double entrance; tests have demonstrated good resistance to water jets under a pressure of around 4 bars;
    • the "breathing" of the lighting or signaling device, that is to say the successive states of depression / overpressure appearing in use or during successive ignitions / extinctions, causes a forced circulation of air towards the inside the device, which is likely to cause dust; this phenomenon is strongly limited on the one hand by the presence of a double air inlet, and on the other hand by the possible presence of the filter 300 which, by creating a pressure drop, reduces the air draw;

    Enfin le montage du dispositif de ventilation, par simple engagement élastique du bouchon, est simple; la tennue mécanique reste satisfaisante même après vieillissement; en outre, le fait que le filtre mousse éventuellement prévu puisse être monté sur le bouchon avant assemblage facilite l'industrialisation.Finally the assembly of the ventilation device, by simple elastic engagement of the plug, is simple; the mechanical strength remains satisfactory even after aging; in addition, the fact that the foam filter possibly provided can be mounted on the front cap assembly facilitates industrialization.

    Bien entendu, étant donné l'efficacité inhérente de l'entrée d'air en "T" et de la chicane montante, le filtre 300 peut être omis comme on l'a indiqué plus haut.Of course, given the inherent effectiveness of "T" air inlet and rising baffle, filter 300 can be omitted as indicated above.

    Bien entendu, la présente invention n'est nullement limitée aux formes de réalisation décrites et représentées, mais l'homme de l'art saura y apporter toute variante ou modification dans la limite des revendications annexées.Of course, the present invention is by no means limited to the embodiments described and shown, but the person skilled in the art will be able to bring there any variant or modification within the limits of the appended claims.
