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 qu'il faut assurer la sortie de l'air plus ou moins chargé en humidité qui peut pénétrer dans le projecteur, selon les pressions différentielles pouvant exister, en même temps qu'on doit éviter toute pénétration d'eau, de boue, desalissures, etc.. dans ledit espace intérieur.A constant concern in the design of a device for ventilating the interior space of a projector is that it is necessary to ensure the exit of air more or less charged with moisture which can enter the projector, according to differential pressures that may exist, at the same time that any penetration of water, mud, fouling, 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.

Il est classique par ailleurs, comme l'enseigne notamment le document FR-A- 2 212 794, de concevoir l'orifice de ventilation dans une partie par exemple cylindrique faisant saillie à partir du boîtier vers l'extérieur et fermée à son extrémité libre par un bouchon, le passage d'air s'étendant de l'espace intérieur du projecteur jusqu'à ladite extrémité libre puis à partir de cette extrémité, à nouveau en direction du boîtier et communiquant d'une façon ou d'une autre avec l'extérieur.It is moreover conventional, as taught in particular in document FR-A-2 212 794, to design the ventilation orifice in a part, for example cylindrical projecting from the housing towards the outside and closed at its free end. by a plug, the air passage extending from the interior space of the projector to said free end then from this end, again towards the housing and communicating in one way or another with outside.

Cet orifice de ventilation connu présente cependant un certain nombre d'inconvénients. Tout d'abord, il peut s'avérer satisfaire imparfaitement aux exigences précitées, en particulier lorsque le projecteur est directement exposé au jet d'un nettoyeur à haute pression ou analogue, en particulier du fait de la configuration du trajet de ventilation. En outre, la qualité de l'étanchéité entre le bouchon et l'extrémité du prolongement cylindrique, qui est déterminante pour éviter toute pénétration de boue, peut se dégrader avec le temps, et le bouchon peut même se séparer complètement du boîtier, ce qui peut conduire à des pénétrations massives de matières étrangères dans l'espace intérieur du projecteur.This known ventilation orifice however has a number of drawbacks. First, it may be found to imperfectly meet the above requirements, in particular when the projector is directly exposed to the jet of a high pressure cleaner or the like, in particular due to the configuration of the ventilation path. In addition, the quality of the seal between the plug and the end of the cylindrical extension, which is decisive in preventing any penetration of mud, can deteriorate over time, and the plug can even separate completely from the housing, which can lead to massive penetrations foreign matter inside the projector.

La présente invention vise à pallier ces inconvénients, et ceci sans notablement accroître le coût de revient du projecteur et sans augmenter son encombrement extérieur.The present invention seeks to overcome these drawbacks, without significantly increasing the cost of the projector and without increasing its external dimensions.

On connaît également par GB-A-2 237 626 un projecteur selon le préambule de la revendication 1.GB-A-2 237 626 also discloses a projector according to the preamble of claim 1.

La présente invention vise également à améliorer un tel projecteur en empêchant de façon plus sûre toute pénétration d'eau à l'intérieur de celui-ci sous l'effet de projections d'eau violentes (par exemple jets de lavage) voire même lors d'une immersion partielle du projecteur.The present invention also aims to improve such a projector by preventing more safely any penetration of water inside thereof under the effect of violent water splashes (for example washing jets) or even during '' partial immersion of the projector.

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.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante d'une forme de réalisation préférée de celle-ci, donnée à titre d'exemple et faite en référence au dessin annexé, sur lequel :

  • la figure 1 est une vue en coupe verticale axiale d'une partie d'un boîtier de projecteur équipée d'un passage de ventilation, et
  • les figures 2, 3 et 4 sont des vues en coupe transversale respectivement selon les lignes II-II, III-III et IV-IV de la figure 1.
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 example and made with reference to the appended drawing, in which :
  • Figure 1 is an axial vertical sectional view of a portion of a projector housing equipped with a ventilation passage, and
  • Figures 2, 3 and 4 are cross-sectional views respectively along lines II-II, III-III and IV-IV of Figure 1.

En référence maintenant aux figures, la référence 100 désigne une paroi, par exemple la paroi arrière, d'un boîtier de projecteur.Referring now to the figures, the reference 100 designates 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 et également de contour généralement cylindrique d'axe horizontal.Towards the inside of the housing (to the left) extends a second projecting part 120, preferably also molded and also of generally cylindrical outline with a horizontal axis.

On observe d'ores et déjà que les parties en saillie 110 et 120 ne sont pas coaxiales, l'axe de la partie 120 tournée vers l'intérieur étant plus haut que celui de la partie 110.It is already observed that the projecting parts 110 and 120 are not coaxial, the axis of the part 120 facing inwards being higher than that of the part 110.

L'extrémité axiale libre de chaque partie cylindrique est ouverte. Deux bouchons, respectivement 130 et 140, sont montés de façon amovible sur lesdites extrémités pour les obturer. Les deux bouchons sont de préférence strictement identiques, afin notamment de limiter les coûts de conception et de fabrication en ayant une référence de pièce unique, et comportent de façon classique en soi une partie circulaire d'obturation, respectivement 131, 141, et une collerette périphérique orientée essentiellement axialement, respectivement 132, 142.The free axial end of each cylindrical part is open. Two plugs, respectively 130 and 140, are removably mounted on said ends to close them. The two plugs are preferably strictly identical, in particular in order to limit the design and manufacturing costs by having a single part reference, and conventionally comprise per se a circular shutter part, respectively 131, 141, and a flange essentially axially oriented device, respectively 132, 142.

Le maintien en place des bouchons est assuré par la force élastique de serrage exercée par lesdites collerettes sur l'extérieur des parties en saillie respectives, les bouchons étant réalisés par exemple en caoutchouc.The plugs are held in place by the elastic clamping force exerted by said flanges on the outside of the respective projecting parts, the plugs 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 cylindrique 120 comporte une fente analogue 121, ménagée longitudinalement dans sa région supérieure.The cylindrical part 110 comprises, over its entire longitudinal extent and in its lower region, a slot 111. The cylindrical part 120 comprises a similar slot 121, formed longitudinally in its upper region.

Une cloison formant chicane 112 s'étend dans la partie en saillie 110 à partir de la paroi 100, essentiellement parallèlement à l'axe de ladite partie, et s'arrête à une certaine distance de l'extrémité libre de ladite partie 110. La cloison 112 présente, dans sa partie centrale principale 112a, une forme généralement semi-cylindrique , de rayon inférieur à celui de la partie 110 et dont la concavité est tournée vers le haut. Deux parties latérales 112b, 112c essentiellement planes et horizontales de la cloison réunissent ladite partie semi-cylindrique avec les parois de la partie 110 qui l'entoure.A baffle-like partition 112 extends in the projecting part 110 from the wall 100, essentially parallel to the axis of said part, and stops at a certain distance from the free end of said part 110. partition 112 has, in its main central part 112a, a generally semi-cylindrical shape, of radius smaller than that of part 110 and whose concavity is turned upwards. Two essentially flat and horizontal side parts 112b, 112c of the partition join said semi-cylindrical part with the walls of the part 110 which surrounds it.

De même, une cloison formant chicane 122 s'étend dans la partie 120 à partir de la paroi 100, jusqu'à une certaine distance de l'extrémité libre de ladite partie 120, et possède une partie centrale principale 122a de forme générale semi-cylindrique dont la concavité est tournée cette fois vers le bas, et deux parties latérales planes et horizontales 122b et 122c qui réunissent ladite partie semi-cylindrique avec la paroi de ladite partie 120 située autour.Similarly, a baffle-shaped partition 122 extends in the part 120 from the wall 100, up to a certain distance from the free end of said part 120, and has a main central part 122a of generally semi- cylindrical, the concavity of which is turned downwards, and two flat and horizontal lateral parts 122b and 122c which join said semi-cylindrical part with the wall of said part 120 situated around.

On observe ici que la section des parois des parties 110 et 120 et de leurs cloisons 112, 122 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 their partitions 112, 122 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 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 cloison 122 et la région inférieure de la paroi de la partie en saillie 120.Finally the wall 100 of the housing has a 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 protruding part 110 and on the other side in the channel C2 delimited through partition 122 and the region bottom of the wall of 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, par le canal C1 suivi du canal C2, par un autre coude à environ 180° vers le haut entre le bord libre en direction axiale de la cloison 122 et le bouchon 140, puis par un canal C4 situé dans l'espace intérieur de la partie 120 au-dessus de la cloison 122, entre celle-ci et la collerette 142 du bouchon 140, et enfin par la fente 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 about 180 ° upwards between the free edge in the axial direction of the partition 112 and the plug 130, via the channel C1 followed from the channel C2, by another bend at about 180 ° upwards between the free edge in the axial direction of the partition 122 and the plug 140, then by a channel C4 located in the interior space of the part 120 above the partition 122, between the latter and the flange 142 of the plug 140, and finally by the slot 121.

On définit ainsi, sans que l'encombrement extérieur du boîtier ne soit augmenté par rapport à une solution classique, 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 double coude à environ 180° vers le haut. Le coût de revient du projecteur n'est pas sensiblement accru, les parties 110 et 120 étant avantageusement venues de moulage avec le boîtier du projecteur et seul un deuxième bouchon, de préférence du même modèle que le premier, étant à prévoir.A ventilation path is thus defined, without the external space requirement of the housing being increased compared to a conventional solution, which protects the projector quite effectively against the penetration of water, mud etc., in particular thanks to the double bend at about 180 ° upwards. The cost price of the projector is not appreciably increased, the parts 110 and 120 having advantageously come from molding with the housing of the projector and only a second plug, preferably of the same model as the first, being to be provided.

Par ailleurs, dans le cas où le bouchon extérieur 130 viendrait à souffrir d'un défaut d'étanchéité ou à se séparer de la partie cylindrique extérieure 110, le dispositif de ventilation selon l'invention continue à présenter une certaine efficacité vis-à-vis des pénétrations d'eau ou de boue grâce au coude à 180° vers le haut subsistant dans la partie intérieure 120.Furthermore, in the case where the outer plug 130 would suffer from a leak or to separate from the outer cylindrical part 110, the ventilation device according to the invention continues to have a certain efficiency with respect to screw penetrations of water or mud thanks to the 180 ° upward bend remaining in the inner part 120.

En variante, 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, tout en restant dans le cadre défini par les revendications.Alternatively, a projector can be fitted 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, while remaining within the defined framework. by the claims.
