Description

L'invention concerne notamment un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile.The invention relates in particular to a lighting and / or signaling device of a motor vehicle.

Dans les dispositifs d'éclairage et/ou de signalisation d'un certain type, de l'eau issue de la condensation ou issue d'une infiltration non désirée, par exemple par une mauvaise fixation d'un couvercle, peut s'accumuler dans l'espace intérieur de ces dispositifs.In lighting and / or signaling devices of a certain type, water resulting from condensation or from unwanted infiltration, for example by improperly fastening a lid, may accumulate in the interior space of these devices.

Une solution pour évacuer cette eau est de prévoir un orifice en un point bas du dispositif.One solution for evacuating this water is to provide an orifice at a low point of the device.

Toutefois cet orifice, s'il permet d'évacuer l'eau accumulée dans l'espace intérieur du dispositif, constitue un passage pour les particules de poussière qui pénètrent dans l'espace intérieur du dispositif. Ceci n'est pas souhaitable.However, this hole, if it allows to evacuate the water accumulated in the interior space of the device, is a passage for the dust particles that penetrate into the interior space of the device. This is not desirable.

L'invention vise notamment à remédier à cet inconvénient.The invention aims in particular to remedy this drawback.

L'invention a ainsi pour objet un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, ce dispositif comportant :

  • une enceinte comportant une ouverture,
  • un couvercle agencé pour fermer l'ouverture de l'enceinte,
  • un réservoir pouvant communiquer avec l'enceinte de manière à recueillir un liquide présent dans l'enceinte, ce réservoir étant agencé pour pouvoir être purgé.
The invention thus relates to a lighting and / or signaling device of a motor vehicle, this device comprising:
  • an enclosure having an opening,
  • a cover arranged to close the opening of the enclosure,
  • a tank that can communicate with the chamber so as to collect a liquid present in the chamber, this tank being arranged to be purged.

L'invention permet, d'une part, d'éviter que de l'eau, par exemple qui a pénétré par projection dans l'enceinte à la faveur d'une mauvaise fixation du couvercle, ne s'accumule dans l'enceinte, et d'autre part, d'empêcher l'introduction indésirable de poussières dans l'enceinte en fonctionnement habituel du dispositif.The invention makes it possible, on the one hand, to prevent water, for example which has penetrated by projection into the chamber due to poor attachment of the lid, from accumulating in the chamber, and secondly, to prevent the undesirable introduction of dust into the chamber in usual operation of the device.

De préférence, le réservoir est agencé de manière à pouvoir être purgé sans avoir à ouvrir le couvercle de l'enceinte.Preferably, the reservoir is arranged to be able to be purged without having to open the lid of the enclosure.

Le réservoir est de préférence distinct du couvercle.The reservoir is preferably separate from the lid.

Avantageusement, lorsque le couvercle et le réservoir sont correctement montés sur l'enceinte, celle-ci est rendue étanche aux particules de poussière.Advantageously, when the lid and the tank are correctly mounted on the enclosure, the latter is sealed against dust particles.

Le dispositif comporte au moins une source lumineuse, par exemple une LED ou une lampe, disposée dans l'enceinte.The device comprises at least one light source, for example an LED or a lamp, disposed in the enclosure.

Si on le souhaite, le dispositif comporte au moins un réflecteur associé à la source lumineuse pour former un faisceau souhaité, et disposé dans l'enceinte.If desired, the device comprises at least one reflector associated with the light source to form a desired beam, and disposed in the enclosure.

Par exemple, le dispositif peut comporter une pluralité de sources lumineuses et une pluralité de réflecteurs associés.For example, the device may include a plurality of light sources and a plurality of associated reflectors.

Dans un exemple de mise en oeuvre de l'invention, le dispositif comporte au moins un ventilateur disposé dans l'enceinte et agencé pour générer un flux d'air de refroidissement dans cette enceinte.In an exemplary implementation of the invention, the device comprises at least one fan disposed in the enclosure and arranged to generate a flow of cooling air in this enclosure.

Le cas échéant, le dispositif comporte au moins un conduit agencé pour diriger un flux d'air généré par le ventilateur vers une zone prédéterminée de l'enceinte.Where appropriate, the device comprises at least one duct arranged to direct a flow of air generated by the fan to a predetermined zone of the enclosure.

Le dispositif peut, si on le souhaite, comporter plusieurs ventilateurs et/ou conduits associés.The device may, if desired, have several fans and / or associated ducts.

Dans un exemple de mise en oeuvre de l'invention, l'enceinte comporte un orifice fermé par une membrane respirante formant barrière à l'eau liquide tout en laissant passer de l'air.In an exemplary implementation of the invention, the enclosure comprises an orifice closed by a breathable membrane forming a liquid water barrier while allowing air to pass.

Si on le souhaite, la membrane présente une forme sensiblement en pastille. Cependant cette membrane peut présenter toute autre forme adéquate.If desired, the membrane has a substantially pelletized shape. However, this membrane may have any other suitable form.

Avantageusement l'orifice fermé par la membrane respirante est disposé sensiblement en regard du ventilateur.Advantageously, the orifice closed by the breathable membrane is disposed substantially facing the fan.

De préférence le réservoir communique avec l'enceinte par l'intermédiaire d'un passage situé en un point bas de l'enceinte.Preferably the reservoir communicates with the enclosure via a passage located at a low point of the enclosure.

Dans un exemple de mise en oeuvre de l'invention, le passage entre l'enceinte et le réservoir comporte une chicane.In an exemplary implementation of the invention, the passage between the chamber and the reservoir comprises a baffle.

En variante, ce passage peut être dépourvu de chicane.Alternatively, this passage may be devoid of baffle.

Le cas échéant, le réservoir est monté sur l'enceinte de manière amovible de sorte que, pour purger le réservoir, celui-ci peut être séparé et éloigné de l'enceinte.If necessary, the tank is mounted on the enclosure removably so that, to purge the tank, it can be separated and removed from the enclosure.

Par exemple le réservoir est agencé pour pouvoir être vissé sur l'enceinte.For example the reservoir is arranged to be screwed on the enclosure.

En variante, le réservoir est agencé pour pouvoir être encliqueté sur l'enceinte.Alternatively, the reservoir is arranged to be snapped onto the enclosure.

En variante encore, la fixation entre le réservoir et l'enceinte peut être obtenue à l'aide d'une vis.In another variant, the attachment between the reservoir and the enclosure can be obtained using a screw.

Si on le souhaite, le réservoir comporte une coupelle.If desired, the tank has a cup.

Cette coupelle est par exemple fixée sur un fond de l'enceinte.This cup is for example fixed on a bottom of the enclosure.

En variante, le réservoir est fixé à demeure sur l'enceinte et par le fait que le réservoir est muni d'un bouchon amovible agencé pour permettre la purge du réservoir.Alternatively, the tank is fixed permanently on the enclosure and in that the tank is provided with a removable plug arranged to allow the purge of the tank.

Par exemple le volume du réservoir est plus faible, notamment au moins deux ou dix fois plus faible, que celui de l'enceinte.For example the volume of the tank is lower, especially at least two or ten times lower than that of the enclosure.

Dans un exemple de mise en oeuvre de l'invention, le réservoir est réalisé en matière plastique, notamment d'un seul tenant.In an exemplary implementation of the invention, the tank is made of plastic material, in particular in one piece.

Le cas échéant, le réservoir comporte au moins une nervure extérieure agencée pour faciliter une préhension du réservoir par une personne.Where appropriate, the reservoir comprises at least one outer rib arranged to facilitate gripping of the reservoir by a person.

Avantageusement, lorsque le réservoir est en place sur l'enceinte, cette enceinte communique avec l'extérieur uniquement via la membrane pour le passage de l'air, de sorte que de la poussière ne puisse pas pénétrer dans l'enceinte.Advantageously, when the reservoir is in place on the enclosure, this enclosure communicates with the outside only via the membrane for the passage of air, so that dust can not enter the enclosure.

L'invention a également pour objet un procédé pour évacuer un liquide d'une enceinte d'un dispositif d'éclairage et/ou de signalisation de véhicule automobile, le procédé comportant l'étape suivante :

  • permettre l'évacuation d'un liquide présent dans l'enceinte, tout en empêchant la pénétration de poussières dans l'enceinte, notamment à l'aide d'un filtre perméable au liquide et imperméable aux poussières, placé en un point bas de l'enceinte.
The invention also relates to a method for discharging a liquid from an enclosure of a lighting and / or signaling device of a motor vehicle, the method comprising the following step:
  • allow the evacuation of a liquid present in the chamber, while preventing the entry of dust into the chamber, in particular by means of a filter permeable to liquid and impervious to dust, placed at a low point of the 'pregnant.

Le procédé peut en outre comporter les étapes suivantes :

  • monter sur l'enceinte, notamment de manière amovible, un réservoir, notamment en un point bas de l'enceinte,
  • vider le réservoir du liquide accumulé dans ce réservoir, notamment en séparant le réservoir de l'enceinte, ou en variante en purgeant le réservoir via une vis de vidange sur le réservoir (qui peut demeurer sur l'enceinte lors de la purge) ou tout autre type de système de purge.
The method may further comprise the following steps:
  • mounting on the enclosure, particularly removably, a tank, in particular at a low point of the enclosure,
  • empty the tank of the liquid accumulated in this tank, in particular by separating the tank from the chamber, or alternatively by purging the tank via a drain screw on the tank (which can remain on the chamber during the purge) or any other type of purge system.

L'invention pourra être mieux comprise à la lecture de la description détaillée qui va suivre, d'un exemple de mise en oeuvre non limitatif de l'invention, et à l'examen du dessin annexé, sur lequel :

  • la figure 1 représente, schématiquement et partiellement, en coupe, un dispositif conforme à un exemple de mise en oeuvre de l'invention.
The invention will be better understood on reading the following detailed description of an example of non-limiting implementation of the invention, and on examining the appended drawing, in which:
  • the figure 1 shows, schematically and partially, in section, a device according to an exemplary implementation of the invention.

On a représenté sur la figure 1 un dispositif d'éclairage et/ou de signalisation 1 d'un véhicule automobile, ce dispositif comportant :

  • une enceinte 2 comportant une ouverture 3,
  • un couvercle 4 agencé pour fermer l'ouverture 3 de ladite enceinte 2,
  • un réservoir 10 pouvant communiquer avec l'enceinte 2 de manière à recueillir un liquide présent dans l'enceinte, ce réservoir étant agencé pour pouvoir être purgé.
We have shown on the figure 1 a lighting and / or signaling device 1 of a motor vehicle, this device comprising:
  • an enclosure 2 having an opening 3,
  • a cover 4 arranged to close the opening 3 of said enclosure 2,
  • a reservoir 10 that can communicate with the chamber 2 so as to collect a liquid present in the chamber, this reservoir being arranged to be purged.

Le dispositif 1 est par exemple un projecteur qui fait une fonction d'éclairage principale.The device 1 is for example a projector which is a main lighting function.

L'enceinte 2 est formée par un boîtier 5 fermé à l'avant par une glace 6. L'ouverture 3 est située à l'arrière du boîtier 5.The enclosure 2 is formed by a housing 5 closed at the front by a window 6. The opening 3 is located at the rear of the housing 5.

Ce boîtier 5 comporte en outre un orifice 8 fermé par une membrane respirante 9 formant barrière à l'eau liquide tout en laissant passer de l'air.This housing 5 further comprises an orifice 8 closed by a breathable membrane 9 forming a liquid water barrier while allowing air to pass.

Cette membrane 9 est par exemple du type de la marque commerciale Goretex.This membrane 9 is for example of the type of the trademark Goretex.

Le dispositif 1 comporte une source lumineuse 12, par exemple une LED, disposée dans l'enceinte 2.The device 1 comprises a light source 12, for example an LED, disposed in the enclosure 2.

Le dispositif 1 comporte en outre un réflecteur 13 associé à la source lumineuse 12 et disposé dans l'enceinte 2.The device 1 further comprises a reflector 13 associated with the light source 12 and disposed in the enclosure 2.

Le dispositif 1 comporte également un ventilateur 15 disposé dans l'enceinte 2 et agencé pour générer un flux d'air de refroidissement dans cette enceinte.The device 1 also comprises a fan 15 disposed in the chamber 2 and arranged to generate a flow of cooling air in this chamber.

Le cas échéant, le dispositif 1 comporte au moins un conduit 16 (en pointillés sur la figure 1) agencé pour diriger un flux d'air généré par le ventilateur 15 vers une zone prédéterminée de l'enceinte 2, par exemple à proximité de la source lumineuse 12.Where appropriate, the device 1 comprises at least one duct 16 (in dotted lines on the figure 1 ) arranged to direct a flow of air generated by the fan 15 to a predetermined zone of the chamber 2, for example near the light source 12.

La membrane 9 présente, dans l'exemple décrit, une forme sensiblement en pastille.The membrane 9 has, in the example described, a substantially pelletized form.

L'orifice 8 fermé par la membrane respirante 9 est disposé sensiblement en regard du ventilateur 15 pour favoriser le flux d'air de refroidissement.The orifice 8 closed by the breathable membrane 9 is disposed substantially opposite the fan 15 to promote the flow of cooling air.

Le réservoir 10 communique avec l'enceinte 2 par l'intermédiaire d'un passage 17 situé en un point bas de l'enceinte 2.The reservoir 10 communicates with the enclosure 2 via a passage 17 located at a low point of the enclosure 2.

Ce passage 17 entre l'enceinte 2 et le réservoir 10 comporte, dans l'exemple décrit, une chicane 19, pour éviter un retour du liquide L dans l'enceinte 2.This passage 17 between the enclosure 2 and the reservoir 10 comprises, in the example described, a baffle 19, to prevent a return of the liquid L in the enclosure 2.

En variante, le passage 17 peut être dépourvu de chicane.Alternatively, the passage 17 may be devoid of baffle.

Le réservoir 10 est monté sur le boîtier 5 de manière amovible de sorte que, pour purger le réservoir, celui-ci 10 peut être séparé et éloigné de l'enceinte 2.The reservoir 10 is mounted on the housing 5 removably so that, to purge the reservoir, the latter 10 can be separated and moved away from the enclosure 2.

Par exemple le réservoir 10 est agencé pour pouvoir être vissé sur le boîtier 5 à l'aide d'un col fileté 23.For example, the reservoir 10 is arranged to be screwed onto the housing 5 by means of a threaded neck 23.

En variante, le réservoir 10 est agencé pour pouvoir être encliqueté sur l'enceinte 2.In a variant, the reservoir 10 is arranged to be able to be snapped onto the enclosure 2.

Le réservoir 10 comporte une coupelle 20 par exemple de forme sensiblement cylindrique.The reservoir 10 comprises a cup 20, for example of substantially cylindrical shape.

Par exemple le volume du réservoir 10 est plus faible, notamment au moins deux ou dix fois plus faible, que celui de l'enceinte 2.For example, the volume of the tank 10 is smaller, in particular at least two or ten times smaller, than that of the chamber 2.

Le réservoir 10 est par exemple réalisé en matière plastique, notamment d'un seul tenant.The reservoir 10 is for example made of plastic material, in particular in one piece.

Ce réservoir 10 comporte des nervures extérieures 21 agencées pour faciliter une préhension du réservoir 10 par une personne.This tank 10 has outer ribs 21 arranged to facilitate gripping of the tank 10 by a person.

Bien entendu, l'invention n'est pas limitée à l'exemple de mise en oeuvre qui vient d'être décrit.Of course, the invention is not limited to the implementation example which has just been described.

Par exemple il est possible d'évacuer un liquide d'une enceinte d'un dispositif d'éclairage et/ou de signalisation de véhicule automobile, en permettant l'évacuation d'un liquide présent dans l'enceinte, tout en empêchant la pénétration de poussières dans l'enceinte, notamment à l'aide d'un filtre perméable au liquide et imperméable aux poussières placé en un point bas de l'enceinte.For example it is possible to evacuate a liquid from an enclosure of a lighting device and / or signaling of a motor vehicle, allowing the evacuation of a liquid present in the chamber, while preventing the entry of dust into the chamber, in particular by means of a permeable filter to the liquid and impervious to dust placed at a low point of the enclosure .

Ce filtre est par exemple placé dans le passage 17 décrit ci-dessus, à la place du réservoir 10 qui peut être omis.This filter is for example placed in the passage 17 described above, instead of the tank 10 which can be omitted.
