Description

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

Ce dispositif d'éclairage et/ou de signalisation est notamment agencé pour produire un éclairage pour éclairer la route et/ou une signalisation pour permettre au véhicule d'être vu d'autres usagers de la route.This lighting and / or signaling device is in particular designed to produce lighting to illuminate the road and / or signaling to allow the vehicle to be seen by other road users.

De manière habituelle, un tel dispositif d'éclairage et/ou de signalisation comporte, outre le boîtier, une glace prévue pour être fixée de manière étanche sur ce boîtier.Usually, such a lighting and / or signaling device comprises, in addition to the housing, a glass designed to be fixed in a sealed manner to this housing.

Il est connu, pour réaliser cette fixation, de coller la glace sur le boîtier.It is known, to achieve this fixing, to glue the glass to the housing.

Afin de maintenir temporairement la glace sur le boîtier pendant la prise de la colle, il est généralement prévu des moyens de maintien mécanique présents sur la glace et sur le boîtier, moyens qui coopèrent ensemble.In order to temporarily hold the crystal on the case while the adhesive sets, there are generally provided mechanical holding means present on the crystal and on the case, means which cooperate together.

Cependant, ces moyens de maintien sont visibles à travers la glace, ce qui nécessite d'aménager la carrosserie aux abords de la glace pour dissimuler ces moyens de maintien.However, these retaining means are visible through the glass, which necessitates arranging the bodywork in the vicinity of the glass in order to conceal these retaining means.

L'invention vise notamment à pallier l'inconvénient ci-dessus.The invention aims in particular to overcome the above drawback.

Un boîtier d'éclairage et/ou de signalisation comportant une gorge de collage et au moins un élément de maintien de la glace sur le boîtier est connu de FR 2 710 395 A1 .A lighting and / or signaling box comprising a bonding groove and at least one element for retaining the glass on the box is known from FR 2 710 395 A1 .

L'invention a ainsi notamment pour objet un boîtier d'un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, ce boîtier étant agencé pour coopérer avec une glace, et comportant les caractéristiques de la revendication 1.A particular subject of the invention is thus a housing for a lighting and / or signaling device for a motor vehicle, this housing being arranged to cooperate with a glass, and comprising the characteristics of claim 1.

Grâce à l'invention, l'élément de maintien qui est au moins partiellement dans la gorge de collage est facilement dissimulable.Thanks to the invention, the retaining element which is at least partially in the bonding groove is easily concealed.

Ceci permet de rendre, de manière simple, l'élément de maintien totalement invisible à travers la glace une fois le dispositif assemblé.This makes it possible to make, in a simple manner, the retaining element completely invisible through the glass once the device has been assembled.

L'invention permet notamment d'éviter d'avoir à concevoir une carrosserie spécifique pour dissimuler cet élément de maintien.The invention makes it possible in particular to avoid having to design a specific body to conceal this retaining element.

La gorge de collage est formée entre un rebord intérieur et un rebord extérieur et le rebord extérieur entoure au moins partiellement le rebord intérieur.The bonding groove is formed between an inner rim and an outer rim and the outer rim at least partially surrounds the inner rim.

Si on le souhaite, le rebord extérieur de la gorge de collage s'étend sensiblement sur tout un pourtour du boîtier. Conformément à l'invention, le rebord intérieur comporte au moins une ouverture en regard de l'élément de maintien.If desired, the outer rim of the bonding groove extends substantially over an entire periphery of the housing. According to the invention, the inner rim has at least one opening facing the retaining element.

Cette ouverture permet notamment de mouler le boîtier de manière relativement simple, comme cela sera expliqué en détail plus loin.This opening makes it possible in particular to mold the case in a relatively simple manner, as will be explained in detail below.

Le cas échéant, l'élément de maintien peut être formé sur le rebord extérieur, en regard de l'ouverture du rebord intérieur.Where appropriate, the retaining element may be formed on the outer rim, facing the opening of the inner rim.

Dans un exemple de réalisation de l'invention, l'un au moins des rebords intérieur et extérieur d'une part, et le boîtier d'autre part, sont réalisés d'un seul tenant.In an exemplary embodiment of the invention, at least one of the inner and outer flanges on the one hand, and the housing on the other hand, are made in one piece.

Ces rebords et le boîtier sont éventuellement réalisés par moulage, par exemple par moulage par injection d'une matière plastique.These rims and the housing are optionally produced by molding, for example by injection molding of a plastic material.

Si on le souhaite, lorsque l'ouverture du rebord intérieur et l'élément de maintien sont observés suivant un axe sensiblement perpendiculaire à un plan de l'ouverture, l'élément de maintien peut apparaître inscrit dans l'ouverture.If desired, when the opening of the inner rim and the retaining member are observed along an axis substantially perpendicular to a plane of the opening, the retaining member may appear inscribed in the opening.

De préférence, l'élément de maintien s'étend entièrement dans la gorge de collage.Preferably, the retaining element extends entirely into the bonding groove.

L'élément de maintien peut comporter au moins une patte d'encliquetage.The retaining element may include at least one latching tab.

Dans un exemple de mise en œuvre de l'invention, il est prévu sur le boîtier au moins un organe de fixation agencé pour coopérer avec une pièce intermédiaire, laquelle pièce comporte une cloison agencée pour fermer l'ouverture du rebord intérieur.In an exemplary implementation of the invention, there is provided on the housing at least one fixing member arranged to cooperate with an intermediate part, which part comprises a partition arranged to close the opening of the inner rim.

Le cas échéant, cet organe de fixation peut être formé sur le rebord intérieur de la gorge de collage, cet organe de fixation étant de préférence en dehors de la gorge de collage.Where appropriate, this fixing member may be formed on the inner rim of the bonding groove, this fixing member preferably being outside of the bonding groove.

Cet organe de fixation peut être formé sur une face du rebord intérieur qui est parallèle à l'ouverture.This fixing member can be formed on a face of the inner rim which is parallel to the opening.

L'organe de fixation précité peut éventuellement comporter une patte d'encliquetage.The aforementioned fixing member may optionally include a latching tab.

Avantageusement, le boîtier est entièrement réalisé d'un seul tenant, notamment par moulage, par exemple par moulage par injection d'une matière plastique.Advantageously, the housing is produced entirely in one piece, in particular by molding, for example by injection molding of a plastic material.

Cette solution offre l'avantage de rendre la production d'un tel boîtier relativement simple, par exemple en produisant par moulage dans un seul moule les deux rebords, intérieur et extérieur, l'élément de maintien, le cas échéant l'organe de fixation, et le reste du boîtier.This solution offers the advantage of making the production of such a casing relatively simple, for example by producing by molding in a single mold the two edges, interior and exterior, the retaining element, if necessary the fixing member. , and the rest of the case.

L'invention a également pour objet un ensemble pour un dispositif d'éclairage et/ou de signalisation, cet ensemble comportant :

  • un boîtier tel que précédemment décrit, et
  • au moins une pièce intermédiaire,
caractérisé en ce que la pièce intermédiaire comporte une cloison pour fermer, notamment de manière étanche, l'ouverture du rebord intérieur de la gorge de collage du boîtier.The subject of the invention is also an assembly for a lighting and / or signaling device, this assembly comprising:
  • a housing as described above, and
  • at least one intermediate piece,
characterized in that the intermediate part comprises a partition for closing, in particular in a sealed manner, the opening of the inner rim of the gluing groove of the housing.

Il est ainsi possible de déposer de la colle dans la gorge du boîtier sans que cette colle ne puisse s'échapper de la gorge à travers l'ouverture.It is thus possible to deposit glue in the groove of the housing without this glue being able to escape from the groove through the opening.

Le cas échéant, la pièce intermédiaire peut comporter un orifice apte à coopérer avec l'organe de fixation du boîtier.Where appropriate, the intermediate piece may include an orifice capable of cooperating with the fixing member of the housing.

Si on le souhaite, la pièce intermédiaire forme un masque du dispositif d'éclairage et/ou de signalisation.If desired, the intermediate piece forms a mask of the lighting and / or signaling device.

Ce masque est notamment agencé pour dissimuler certains composants du dispositif, par exemple un actionneur ou un circuit électrique, pour améliorer l'esthétique du dispositif.This mask is in particular designed to conceal certain components of the device, for example an actuator or an electric circuit, to improve the aesthetics of the device.

Le masque peut ainsi comporter au moins une région opaque ou réfléchissante, par exemple aluminée.The mask can thus include at least one opaque or reflecting region, for example aluminized.

Dans un exemple de mise en œuvre de l'invention, la cloison de la pièce intermédiaire fait saillie dans l'ouverture du rebord intérieur pour obstruer cette ouverture.In an exemplary implementation of the invention, the partition of the room intermediate protrudes into the opening of the inner rim to obstruct this opening.

En variante, la cloison de la pièce intermédiaire affleure l'ouverture du rebord intérieur.As a variant, the partition of the intermediate piece is flush with the opening of the interior rim.

Dans un autre exemple de mise en œuvre de l'invention, la cloison comporte une barrette de style.In another example of implementation of the invention, the partition comprises a style bar.

La pièce intermédiaire peut éventuellement comporter une collerette, qui s'étend notamment sur tout un pourtour de la pièce intermédiaire.The intermediate part may optionally include a flange, which extends in particular over an entire periphery of the intermediate part.

Cette collerette vient, par exemple, au moins partiellement, en contact avec la tranche supérieure du rebord intérieur du boîtier.This collar comes, for example, at least partially, in contact with the upper edge of the inner rim of the case.

L'invention a également pour objet un dispositif d'éclairage et/ou de signalisation, comportant :

  • un ensemble tel que précédemment décrit, et
  • une glace de fermeture de boîtier,
caractérisé en ce que la glace est collée dans la gorge de collage du boîtier.The subject of the invention is also a lighting and / or signaling device, comprising:
  • a set as previously described, and
  • a case closing glass,
characterized in that the ice is stuck in the gluing groove of the housing.

La glace peut avantageusement comporter un moyen de maintien complémentaire, agencé pour coopérer, notamment par encliquetage, avec l'élément de maintien du boîtier.The crystal may advantageously include a complementary holding means, arranged to cooperate, in particular by snap-fastening, with the holding element of the housing.

Ce moyen de maintien complémentaire peut, par exemple, comporter une patte d'encliquetage, agencé pour coopérer avec la patte d'encliquetage de l'élément de maintien.This complementary retaining means may, for example, comprise a latching tab, arranged to cooperate with the latching tab of the retaining element.

Si on le souhaite, la glace comporte une face principale lisse, et notamment dépourvue de motifs optiques.If desired, the crystal has a smooth main face, and in particular devoid of optical patterns.

Grâce à l'invention, l'élément de maintien du boîtier est invisible depuis l'extérieur du dispositif.Thanks to the invention, the housing holding element is invisible from outside the device.

Le dispositif peut comporter au moins une source lumineuse, comportant par exemple une diode électroluminescente ou en variante une lampe, pour produire un faisceau lumineux.The device may include at least one light source, comprising for example a light-emitting diode or, in a variant, a lamp, to produce a light beam.

Le cas échéant, le dispositif est agencé pour participer à une fonction photométrique réglementaire, par exemple un éclairage de route, un éclairage de croisement, un indicateur de direction, un feu stop...Where appropriate, the device is designed to participate in a regulatory photometric function, for example road lighting, dipped-beam lighting, a direction indicator, a brake light, etc.

L'invention a également pour objet un procédé de fabrication d'un boîtier tel que précédemment décrit, caractérisé en ce qu'il comporte l'étape suivante :

  • mouler dans un moule une matière plastique afin d'obtenir le boîtier, le moule comportant au moins un tiroir mobile agencé pour former l'élément de maintien du boîtier.
The subject of the invention is also a method of manufacturing a housing as described above, characterized in that it comprises the following step:
  • molding a plastic material in a mold in order to obtain the casing, the mold comprising at least one movable drawer arranged to form the retaining element of the casing.

L'ouverture précitée aménagée sur le rebord intérieur de la gorge de collage permet le déplacement du tiroir du moule, lors du procédé.The aforementioned opening made on the inner rim of the bonding groove allows the movement of the mold drawer, during the process.

L'invention a également pour objet un procédé pour assembler un dispositif d'éclairage et/ou de signalisation tel que décrit plus haut, caractérisé en ce qu'il comporte les étapes suivantes :

Dans l'exemple décrit, les deux rebords, intérieur 21 et extérieur 22, l'organe de fixation 4, l'élément de maintien 3, les nervures 6 et 7 sont réalisés d'un seul tenant avec le reste du boîtier 1.In the example described, the two flanges, interior 21 and exterior 22, the fixing member 4, the retaining element 3, the ribs 6 and 7 are made in a single holding with the rest of the case 1.

Le boîtier 1 est réalisé par moulage par injection d'une matière plastique.The housing 1 is made by injection molding of a plastic material.

L'injection de matière plastique est faite dans un moule adapté pour former le boîtier 1, ce moule comportant au moins un tiroir mobile agencé pour former l'élément de maintien 3 du boîtier 1.The injection of plastic material is made into a mold suitable for forming the housing 1, this mold comprising at least one movable drawer arranged to form the holding element 3 of the housing 1.

Ce tiroir est agencé mobile à travers l'ouverture 23 du rebord intérieur 21 du boîtier 1, dans le sens de la flèche 5, pour permettre le démoulage du boîtier 1.This drawer is arranged to move through the opening 23 of the inner rim 21 of the housing 1, in the direction of arrow 5, to allow the housing 1 to be released from the mold.

On a représenté sur la figure 2 la pièce intermédiaire 10 qui est agencée pour coopérer avec le boîtier 1, pour de manière à fermer l'ouverture 23 du rebord intérieur 21 de la gorge de collage 2.One represented on the figure 2 the intermediate piece 10 which is arranged to cooperate with the housing 1, so as to close the opening 23 of the inner rim 21 of the adhesive groove 2.

La pièce intermédiaire 10 comporte à cet effet une cloison 11 qui fait saillie dans l'ouverture 23 pour obstruer cette ouverture 23.The intermediate part 10 comprises for this purpose a partition 11 which projects into the opening 23 to obstruct this opening 23.

Il est ainsi possible de déposer de la colle dans la gorge 2 du boîtier 1 sans qu'elle ne puisse s'échapper de celle-ci à travers l'ouverture 23.It is thus possible to deposit glue in the groove 2 of the housing 1 without it being able to escape from the latter through the opening 23.

La pièce intermédiaire 10 comporte un orifice 12 agencé pour coopérer par encliquetage avec l'organe de fixation 4 du boîtier 1.The intermediate part 10 comprises an orifice 12 arranged to cooperate by snap-fastening with the fixing member 4 of the housing 1.

Dans l'exemple décrit, l'organe de fixation 4 est formé par une patte élastiquement déformable capable de s'engager par déformation dans l'orifice 12 de la pièce intermédiaire 10.In the example described, the fixing member 4 is formed by an elastically deformable tab capable of engaging by deformation in the orifice 12 of the intermediate part 10.

La pièce intermédiaire 10 forme un masque qui est agencé pour dissimuler certains composants, non représentés ici, par exemple un actionneur ou un circuit électrique.The intermediate piece 10 forms a mask which is arranged to conceal certain components, not shown here, for example an actuator or an electrical circuit.

Le masque 10 comporte une face supérieure 13 opaque ou réfléchissante, par exemple aluminée.The mask 10 has an opaque or reflective upper face 13, for example aluminized.

Le masque 10 comporte une collerette 14, qui s'étend sur tout un pourtour du masque.The mask 10 comprises a collar 14, which extends over an entire periphery of the mask.

Cette collerette 14 vient en appui sur la tranche supérieure 29 du rebord intérieur 21 du boîtier 1.This collar 14 comes to rest on the upper edge 29 of the inner rim 21 of the housing 1.

Comme illustré sur la figure 3, la glace 40 comporte une patte d'encliquetage 42 agencée pour coopérer par encliquetage avec l'élément de maintien 3 du boîtier.As shown on the figure 3 , the glass 40 comprises a latching tab 42 arranged to cooperate by latching with the retaining element 3 of the housing.

En fin de montage, cette patte 42 vient en appui sous la nervure 8 de l'élément de maintien 3.At the end of assembly, this tab 42 comes to rest under the rib 8 of the retaining element 3.

Cette coopération permet le maintien temporaire de la glace 40 sur le boîtier 1 le temps de déposer de la colle 41 dans la gorge de collage 2 pour assurer un assemblage permanent de la glace 40 sur le boîtier 1.This cooperation allows the glass 40 to be temporarily held on the housing 1 while it is time to deposit glue 41 in the bonding groove 2 to ensure permanent assembly of the glass 40 on the housing 1.

La patte d'encliquetage 42 est formée sur une paroi latérale annulaire 45 de la glace 40.The latching tab 42 is formed on an annular side wall 45 of the glass 40.

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

Par exemple, le dispositif 30 pourrait être dépourvu de masque comme décrit plus haut.For example, the device 30 could be devoid of a mask as described above.

Dans ce cas, l'ouverture 23 peut être obstruée par une pièce dédiée, par exemple sous la forme d'une barrette qui s'étend essentiellement dans cette ouverture 23.In this case, the opening 23 may be blocked by a dedicated part, for example in the form of a bar which extends essentially in this opening 23.
