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 ventilation device for the interior space of a headlamp resides in that more or less charged air in humidity must be able to enter or exit the projector, depending on differential pressures may exist at the same time that penetration of water, mud, soiling, etc. in said interior space.
Il est donc connu d'équiper un boítier 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 projector housing with a system of baffles or the like allowing the air circulation while avoiding such penetration.
Le document FR-A-2 660 412 enseigne un dispositif de ventilation qui comporte, du côté extérieur au boítier, un conduit généralement en forme de "U" dont une extrémité ouverte se trouve abritée des projections d'eau directe et, du côté intérieur au boítier, 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 device for ventilation which includes, on the outside of the housing, a generally leads in a "U" shape with one end open is sheltered from direct water splashes and, on the inside of the housing, one opening opening at a time axially and radially in the interior space of the projector. A hydrophobic filter is interposed on the route ventilation.
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 that it has limited effectiveness when you want ability to do without such a hydrophobic filter, in particular when the projector is directly exposed to rain under pressure or when fording.
On connaít 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 boítier de projecteur, et il en résulte une barrière aux pénétrations de liquide qui n'est pas entièrement satisfaisante.We also know from GB-A-2 237 626 a projector according to the preamble of claim 1. In this projector, the second channel of the ventilation device opens directly in the interior space of the projector housing, and this results in a barrier to penetration of liquid 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 acroít le coût de revient de l'ensemble.In addition, the plug described in this document must be include in its fund specific means for the keep away from the free end of the game ventilation system, otherwise the elbow which connects the first and second channels is closed, and ventilation is no longer provided. This increases the cost of comes back from the set.
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 provide ventilation that is not likely to be defect, and an improved liquid barrier effect.
Elle propose à cet effet un projecteur tel que défini dans la revendication 1.To this end, it offers 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 features of claims 1 and 2, the part of the ventilation device without plug can be realized by injection molding without the need for drawers or analogs, i.e. with a simple molding tool and economical, while offering the free end of the part which projects inwards a vertical wall of significant height, favorable to the barrier effect vis-à-vis liquids.
D'autres aspects, buts et avantages de la présente invention apparaítront 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 :

- 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
boítier de projecteur.Referring now to Figures 1 to 3, the
Vers l'extérieur du boítier (vers la droite sur la
figure 1) s'étend une première partie en saillie 110 venue
par exemple de moulage avec le boítier et dont le contour est
en l'espèce généralement cylindrique d'axe horizontal.Towards the outside of the case (to the right on the
Figure 1) extends a
Vers l'intérieur du boítier (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.Inward of the housing (to the left) extends
a second
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
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 force
elastic tightening exerted by its collar on
the outside of the
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
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-
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
boítier.We observe here that the section of the walls of the
Enfin la paroi 100 du boítier 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
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 formed,
in the embodiment described above, through the
On définit ainsi, sans que l'encombrement extérieur du
boítier 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 boítier du
projecteur et seul un bouchon étant à prévoir. On notera à ce
sujet que la configuration du boítier 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.We thus define, without the external bulk of the
housing is important, a ventilation path, which
protects the projector quite effectively against
penetration of water, mud etc ..., in particular thanks to the
has a bend about 180 ° upwards and the fact that
the
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 conducted with the ventilation device according to the invention have put forward a ventilation quite satisfactory and very good test behavior to rain by pressure and 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 boítier vers l'extérieur. De cette manière,
on facilite l'évacuation du liquide ayant pénétré jusque là
notamment lorsque le boítier est exposé à une pluie par
pression.The variant of Figures 4 and 5 differs
of the embodiment described above in that the
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 by no means limited to embodiments described above and shown on the drawings, but those skilled in the art will be able to bring them all variant or modification according to its 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 several ventilation devices as described above, and the shape and dimensions of the various parts can vary widely from those described and represented.
