The outer moulding consists of a full cylinder (110) which has a longitudinal slot (111) along it's lower side. The cylinder (110) is partly covered by a rubber sleeve (131,132) restricting air entry to a part of the slot (111). An internal wall (112) forces incoming air to turn through 180 degrees.

Description

La présente invention a trait d'une façon générale à la ventilation des projecteurs de véhicules automobiles.The present invention relates generally to the ventilation of motor vehicle headlamps.

Une préoccupation constante dans la conception d'un dispositif de ventilation de l'espace intérieur d'un projecteur réside en ce que de l'air plus ou moins chargé en humidité doit pouvoir entrer ou sortir du projecteur, selon les pressions différentielles pouvant exister, en même temps qu'on doit éviter toute pénétration d'eau, de boue, de salissures, etc... dans ledit espace intérieur.A constant concern in the design of a device for ventilating the interior space of a projector is that more or less moisture-laden air must be able to enter or leave the projector, depending on the differential pressures that may exist, at the same time that any penetration of water, mud, dirt, etc., must be avoided in said interior space.

Il est donc connu d'équiper un boîtier de projecteur avec un système de chicanes ou analogues permettant la circulation de l'air tout en évitant de telles pénétrations.It is therefore known to equip a headlamp housing with a system of baffles or the like allowing the circulation of air while avoiding such penetrations.

Le document FR-A-2 660 412 enseigne un dispositif de ventilation qui comporte, du côté extérieur au boîtier, un conduit généralement en forme de "U" dont une extrémité ouverte se trouve abritée des projections d'eau directe et, du côté intérieur au boîtier, un orifice débouchant à la fois axialement et radialement dans l'espace intérieur du projecteur. Un filtre hydrophobe est interposé sur le trajet de ventilation.Document FR-A-2 660 412 teaches a ventilation device which comprises, on the outside of the housing, a duct generally in the shape of a " U " , one open end of which is sheltered from direct water splashes and, on the inside to the housing, an orifice opening both axially and radially into the interior space of the projector. A hydrophobic filter is interposed on the ventilation path.

Un tel dispositif est cenpendant désavantageux en ce qu'il présente une efficacité limitée lorsque l'on souhaite pouvoir se passer d'un tel filtre hydrophobe, en particulier lorsque le projecteur est directement exposé à une pluie sous pression ou lors d'un passage à gué.Such a device is however disadvantageous in that it has limited effectiveness when it is desired to be able to do without such a hydrophobic filter, in particular when the headlight is directly exposed to rain under pressure or during a passage to ford.

On connaît également par GB-A-2 237 626 un projecteur selon le préambule de la revendication 1. Dans ce projecteur, le deuxième canal du dispositif de ventilation s'ouvre directement dans l'espace intérieur du boîtier de projecteur, et il en résulte une barrière aux pénétrations de liquide qui n'est pas entièrement satisfaisante.GB-A-2 237 626 also discloses a projector according to the preamble of claim 1. In this projector, the second channel of the ventilation device opens directly into the interior space of the projector housing, and this results a barrier to liquid penetration which is not entirely satisfactory.

En outre, le bouchon décrit dans ce document doit être comporter en son fond des moyens spécifiques pour le maintenir à distance de l'extrémité libre de la partie extérieure du dispositif de ventilation, faute de quoi le coude qui relie les premier et deuxième canaux est obturé, et la ventilation n'est plus assurée. Ceci acroît le coût de revient de l'ensemble.In addition, the plug described in this document must have specific means at the bottom for the keep away from the free end of the external part of the ventilation device, failing which the elbow which connects the first and second channels is closed, and ventilation is no longer ensured. This increases the cost price of the assembly.

La présente invention vise à pallier ces inconvénients et à assurer une ventilation qui ne risque pas d'être mise en défaut, et un effet de barrière aux liquides amélioré.The present invention aims to overcome these drawbacks and to provide ventilation which is not likely to be faulty, and an improved liquid barrier effect.

Elle propose à cet effet un projecteur tel que défini dans la revendication 1.To this end, it proposes a projector as defined in claim 1.

Des aspects préférés de ce projecteur sont définis dans les sous-revendications. En particulier, grâce aux caractéristiques des revendications 1 et 2, la partie du dispositif de ventilation hors bouchon peut être réalisée par moulage par injection sans recourir à des tiroirs ou analogues, c'est-à-dire avec un outil de moulage simple et économique, et ceci tout en offrant à l'extrémité libre de la partie qui fait saillie vers l'intérieur une paroi verticale de hauteur importante, favorable à l'effet de barrière vis-à-vis des liquides.Preferred aspects of this projector are defined in the subclaims. In particular, thanks to the features of claims 1 and 2, the part of the ventilation device without plug can be produced by injection molding without using drawers or the like, that is to say with a simple and economical molding tool. , and this while providing at the free end of the part which projects inwards a vertical wall of considerable height, favorable to the barrier effect with respect to liquids.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante de formes de réalisation préférées de celle-ci, donnée à titre d'exemple et faite en référence aux dessins annexés, sur lesquels :

  • la figure 1 est une vue en coupe verticale axiale d'une partie d'un boîtier de projecteur équipée d'un passage de ventilation selon une forme de réalisation de base de l'invention,
  • les figures 2, et 3 sont des vues en coupe transversale respectivement selon les lignes II-II et III-III de la figure 1,
  • la figure 4 est une vue en coupe verticale axiale d'une partie d'un boîtier de projecteur équipée d'un passage de ventilation selon une variante de réalisation de l'invention, et
  • la figure5 est une vue en coupe transversale selon la ligne V-V de la figure 4.
Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of preferred embodiments thereof, given by way of example and made with reference to the appended drawings, in which:
  • FIG. 1 is a view in axial vertical section of a part of a headlight housing fitted with a ventilation passage according to a basic embodiment of the invention,
  • FIGS. 2 and 3 are cross-sectional views respectively along lines II-II and III-III of FIG. 1,
  • FIG. 4 is a view in axial vertical section of a part of a headlight housing equipped with a ventilation passage according to an alternative embodiment of the invention, and
  • FIG. 5 is a cross-sectional view along the line VV of FIG. 4.

En référence maintenant aux figures 1 à 3, la référence 100 désigne une paroi, par exemple la paroi arrière, d'un boîtier de projecteur.Referring now to Figures 1 to 3, the reference 100 denotes a wall, for example the rear wall, of a headlight housing.

Vers l'extérieur du boîtier (vers la droite sur la figure 1) s'étend une première partie en saillie 110 venue par exemple de moulage avec le boîtier et dont le contour est en l'espèce généralement cylindrique d'axe horizontal.Towards the outside of the housing (to the right in FIG. 1) extends a first projecting part 110 which comes, for example, from molding with the housing and whose contour in this case is generally cylindrical with a horizontal axis.

Vers l'intérieur du boîtier (vers la gauche) s'étend une seconde partie en saillie 120, de préférence également venue de moulage. Son contour est généralement semi-cylindrique d'axe horizontal. Les parties en saillie 110 et 120 sont en l'espèce coaxiales.Towards the inside of the housing (to the left) extends a second protruding part 120, preferably also molded. Its outline is generally semi-cylindrical with a horizontal axis. The protruding parts 110 and 120 are in this case coaxial.

L'extrémité axiale libre de la partie cylindrique extérieure 110 est ouverte. Un bouchon 130 est monté de façon amovible sur cette extrémité pour l'obturer. Il comporte une partie circulaire d'obturation 131 et une collerette périphérique 132 orientée essentiellement axialement.The free axial end of the outer cylindrical part 110 is open. A plug 130 is removably mounted on this end to close it. It comprises a circular shutter part 131 and a peripheral flange 132 oriented essentially axially.

Le maintien en place du bouchon est assuré par la force élastique de serrage exercée par sa collerette sur l'extérieur de la partie en saillie 110, le bouchon étant réalisé par exemple en caoutchouc.The plug is held in place by the elastic clamping force exerted by its flange on the outside of the projecting part 110, the plug being made for example of rubber.

La partie cylindrique 110 comprend, sur toute son étendue longitudinale et dans sa région inférieure, une fente 111. La partie de contour semi-cylindrique 120 comporte une paroi inférieure plane 124, une paroi supérieure semi-cylindrique 122, une paroi terminale 123 et une ouverture 121 ménagée dans la paroi 122, située à proximité de la paroi terminale 123 et débouchant vers le haut dans l'espace intérieur du projecteur.The cylindrical part 110 comprises, over its entire longitudinal extent and in its lower region, a slot 111. The semi-cylindrical contour part 120 comprises a planar lower wall 124, a semi-cylindrical upper wall 122, an end wall 123 and a opening 121 in the wall 122, located near the wall terminal 123 and opening up into the interior space of the projector.

Une cloison formant chicane 112 s'étend dans la partie en saillie 110 à partir de la paroi 100, dans le prolongement de la paroi 124. Cette cloison 112 est essentiellement parallèle à l'axe de ladite partie 110, et s'arrête à une certaine distance de l'extrémité libre de ladite partie 110. La cloison 112 est en l'espèce plane et horizontale.A baffle-like partition 112 extends in the projecting part 110 from the wall 100, in the extension of the wall 124. This partition 112 is essentially parallel to the axis of said part 110, and stops at a certain distance from the free end of said part 110. The partition 112 is in this case flat and horizontal.

On observe ici que la section des parois des parties 110 et 120 et de la cloison 112 diminue à partir de la paroi 100, ceci notamment afin de faciliter le démoulage du boîtier.It is observed here that the section of the walls of the parts 110 and 120 and of the partition 112 decreases from the wall 100, this in particular in order to facilitate demolding of the housing.

Enfin la paroi 100 du boîtier comporte une ouverture semi-circulaire 101 qui débouche d'un côté dans le canal C1 délimité par la cloison 112 et la région supérieure de la paroi de la partie en saillie 110, et de l'autre côté dans le canal C2 délimité par la partie en saillie 120.Finally, the wall 100 of the housing has a semi-circular opening 101 which opens on one side into the channel C1 delimited by the partition 112 and the upper region of the wall of the projecting part 110, and on the other side in the channel C2 bounded by the projecting part 120.

Ainsi le trajet d'air de ventilation est constitué, dans la forme de réalisation décrite ci-dessus, par la fente 111, par un canal C3 avec lequel la fente 111 communique et qui est défini dans l'espace intérieur de la partie 110 au-dessous de la cloison 112, entre celle-ci et la collerette 132 du bouchon 130, par un coude à environ 180° vers le haut entre le bord libre en direction axiale de la cloison 112 et le bouchon 130, puis par le canal C1 et le canal C2, et enfin par l'ouverture 121.Thus the ventilation air path is constituted, in the embodiment described above, by the slot 111, by a channel C3 with which the slot 111 communicates and which is defined in the interior space of the part 110 at below the partition 112, between the latter and the flange 132 of the plug 130, by a bend at about 180 ° upwards between the free edge in the axial direction of the partition 112 and the plug 130, then through the channel C1 and channel C2, and finally through opening 121.

On définit ainsi, sans que l'encombrement extérieur du boîtier ne soit important, un trajet de ventilation, qui protège tout à fait efficacement le projecteur contre la pénétration d'eau, de boue etc..., notamment grâce à la présente du coude à environ 180° vers le haut et du fait que la partie intérieure 120 est fermée à son extrémité libre en 123 et s'ouvre sur l'espace intérieur du projecteur seulement vers le haut. Le coût de revient de ce dispositif de ventilation est faible, les parties 110 et 120 étant avantageusement venues de moulage avec le boîtier du projecteur et seul un bouchon étant à prévoir. On notera à ce sujet que la configuration du boîtier 100 de projecteur 100 telle que décrite ci-dessus est avantageuse en ce qu'il est possible d'utiliser un moule sans tiroir, ce qui facilite encore la fabrication et diminue le coût de revient.A ventilation path is thus defined, without the external space requirement of the housing being significant, which protects the projector quite effectively against the penetration of water, mud, etc., in particular thanks to the present of the elbow. about 180 ° upwards and the fact that the interior part 120 is closed at its free end at 123 and opens onto the interior space of the projector only to the top. The cost price of this ventilation device is low, the parts 110 and 120 having advantageously come from molding with the projector housing and only a plug being provided. Note in this regard that the configuration of the housing 100 of the projector 100 as described above is advantageous in that it is possible to use a mold without a drawer, which further facilitates manufacture and reduces the cost price.

Des tests conduits avec le dispositif de ventilation selon l'invention ont mis en avant une ventilation tout à fait satisfaisante ainsi qu'un très bon comportement en essai à la pluie par pression et en passage à gué.Tests carried out with the ventilation device according to the invention have shown that ventilation is entirely satisfactory, as well as very good behavior in rain test by pressure and in fording.

La variante de réalisation des figures 4 et 5 diffère de la forme de réalisation décrite ci-dessus en ce que la paroi inférieure 124 de la partie 120 et la cloison 112 située dans son prolongement présentent une pente descendante de l'intérieur du boîtier vers l'extérieur. De cette manière, on facilite l'évacuation du liquide ayant pénétré jusque là notamment lorsque le boîtier est exposé à une pluie par pression.The alternative embodiment of FIGS. 4 and 5 differs from the embodiment described above in that the lower wall 124 of the part 120 and the partition 112 situated in its extension have a downward slope from the interior of the housing towards the 'outside. In this way, it facilitates the evacuation of the liquid that has penetrated so far especially when the housing is exposed to rain by pressure.

Bien entendu, l'invention n'est nullement limitée aux formes de réalisation décrites ci-dessus et représentées sur les dessins, mais l'homme de l'art saura y apporter toute variante ou modification conforme à son esprit.Of course, the invention is in no way limited to the embodiments described above and shown in the drawings, but a person skilled in the art will know how to make any variant or modification in accordance with his spirit.

En particulier, un projecteur peut être équipé d'un ou de plusieurs dispositifs de ventilation comme décrit ci-dessus, et la forme et les dimensions des diverses parties peuvent largement varier par rapport à celles décrites et représentées.In particular, a projector can be equipped with one or more ventilation devices as described above, and the shape and dimensions of the various parts can vary widely from those described and shown.
