Description

La présente invention concerne un projecteur de véhicule automobile avec un élément de masquage contribuant à améliorer la qualité perçue, vue de l'extérieur, de la liaison entre la glace du projecteur et son boîtier.The present invention relates to a motor vehicle headlamp with a masking element contributing to improve the perceived quality, from the outside, of the connection between the projector lens and its housing.

Un projecteur selon l'état de la technique est montré à la figure 1. Ce projecteur comprend une glace 1 de projecteur solidarisée avec le boîtier 2 de ce projecteur. L'assemblage du boîtier 2 et de la glace 1 s'effectue par la retenue de ces deux éléments comprimant entre eux un moyen d'étanchéité et de liaison, le cas échéant mais non obligatoirement, cette retenue étant renforcée à l'aide de moyens de retenue additionnels tels que des agrafes ou des crochets élastiques. Le moyen d'étanchéité et de liaison peut être de la colle, du mastic ou un joint souple.A projector according to the state of the art is shown in figure 1 . This projector comprises a projector lens 1 secured to the housing 2 of this projector. The assembly of the housing 2 and the ice 1 is effected by the retention of these two elements compressing between them a sealing and connecting means, if necessary but not necessarily, this restraint being reinforced by means of additional retainers such as clips or elastic hooks. The sealing and bonding means may be glue, putty or a flexible seal.

Comme moyen d'étanchéité et de liaison, la colle ou le mastic sont souvent préférés, car permettant de se dispenser de l'utilisation de moyens de retenue additionnels précédemment cités. Ce collage peut s'effectuer fréquemment entre la glace 1 et une gorge 2a de collage portée par le boîtier 2. Cette gorge 2a présente en général une forme de U tournée de 90° vers l'extrémité 1a correspondante de la glace 1 et reçoit entre les branches du U, parallèles et horizontales, cette extrémité la de la glace 1. Une couche de colle 3 est alors interposée entre l'extrémité 1a de la glace et les branches du U de la gorge 2a.As a sealing and bonding means, glue or putty is often preferred, since it eliminates the need for the use of additional retaining means mentioned above. This bonding can be done frequently between the glass 1 and a groove 2a bonding carried by the housing 2. This groove 2a generally has a shape of U turned 90 ° to the corresponding end 1a of the ice 1 and receives between the branches of the U, parallel and horizontal, this end of the ice 1. A layer of adhesive 3 is then interposed between the end 1a of the ice and the branches of the U of the groove 2a.

Actuellement, à travers les jeux périphériques d'un projecteur avec son environnement, par exemple, dans le cas d'un projecteur de feu avant, le capot C, les ailes et d'autres éléments environnants de la carrosserie, il est possible d'apercevoir la liaison, c'est-à-dire la zone de collage, entre la glace 1 du projecteur et son boîtier 2 en vue de l'extérieur, ce qui est symbolisé par le faisceau V sur la figure 1.Currently, through the peripheral games of a projector with its environment, for example, in the case of a front light projector, the hood C, the wings and other surrounding elements of the bodywork, it it is possible to see the connection, that is to say the gluing area, between the lens 1 of the headlight and its housing 2 in view of the outside, which is symbolized by the beam V on the figure 1 .

Le processus de collage dans cette zone est aussi souvent mal maîtrisé et le collage reste, dans certains cas, très visible de l'extérieur, notamment quand il se produit un débordement de colle entre l'extrémité 1a de la glace du projecteur et la gorge 2a de collage de ce boîtier 2, la couche de colle 3 débordant de cette gorge 2a en recouvrant une partie de la glace 1 non insérée dans cette gorge 2a.The gluing process in this zone is also often poorly controlled and gluing remains, in some cases, very visible from the outside, especially when there is an overflow of glue between the end 1a of the projector glass and the throat 2a bonding of the housing 2, the adhesive layer 3 projecting from this groove 2a covering a portion of the ice 1 not inserted in this groove 2a.

Pour éviter ce débordement de colle lors de l'assemblage, il est possible de déposer moins de colle, mais ceci entraîne le risque d'un collage déficient dû à un manque de colle. De plus, la limitation de la couche de colle 3 peut engendrer une perte d'étanchéité entre glace 1 et boîtier 2 par manque d'adhésion entre ces deux éléments.To avoid this overflow of glue during assembly, it is possible to deposit less glue, but this entails the risk of a weak bond due to a lack of glue. In addition, the limitation of the adhesive layer 3 can cause a loss of seal between ice 1 and housing 2 due to lack of adhesion between these two elements.

Aujourd'hui, seul le rajout d'un joint périphérique, montré en pointillés à la figure 1 et référencé 4, permet de cacher la liaison entre glace 1 et boîtier 2, matérialisée par la couche de colle 3. L'adaptation d'un joint 4 sur la périphérie de la glace 1 est cependant toujours très délicate car cette solution est appliquée généralement tardivement et n'est pas forcément bien adaptée aux diverses formes de glace. Enfin, cette solution présente le désavantage d'être très coûteuse et d'exiger une manipulation supplémentaire.Today, only the addition of a peripheral seal, shown in dashed lines at the figure 1 and referenced 4, allows to hide the connection between ice 1 and housing 2, materialized by the adhesive layer 3. The adaptation of a seal 4 on the periphery of the ice 1 is however still very delicate because this solution is applied generally late and is not necessarily well adapted to various forms of ice. Finally, this solution has the disadvantage of being very expensive and requiring additional manipulation.

Le document EP-A-632 228 décrit un élément pour dispositif d'éclairage en matière plastique transparente chargée en particules réfléchissant la lumière. Cet élément est destiné à la réalisation de glace de projecteur à zone opaque formant enjoliveurs. Cet élément est appliqué, non sur la partie de glace reliée au boîtier, généralement appelée pied de glace, mais sur une partie supérieure de la glace en prolongement vers le haut pour raccordement avec un élément environnant de la carrosserie du véhicule. Ce document n'aborde pas le problème du masquage de la liaison entre boîtier et glace et ne décrit ni ne suggère aucune solution à ce problème.The document EP-A-632 228 discloses an element for a lighting device of transparent plastics material filled with particles reflecting light. This element is intended for the realization of opaque window projector glass forming hubcaps. This element is applied, not on the part of ice connected to the case, generally called ice foot, but on an upper part of the ice in prolongation towards the high for connection with a surrounding element of the vehicle body. This document does not address the problem of masking the connection between housing and ice and does not describe or suggest any solution to this problem.

La présente invention a pour but de masquer la liaison existante entre la glace du réflecteur et le boîtier de celui-ci pour la rendre non visible de l'extérieur du projecteur.The present invention aims to hide the existing connection between the mirror reflector and the housing thereof to make it invisible from the outside of the projector.

A cet effet, l'invention a pour objet un projecteur pour feu de signalisation d'un véhicule automobile, comprenant une glace dont au moins l'extrémité supérieure est apte à être solidarisée avec le boîtier de ce projecteur par un moyen de liaison, caractérisé en ce que la glace, sur sa partie d'extrémité reliée au boîtier, comprend un élément masquant au moins le moyen de liaison, vu de l'extérieur de ce projecteur.For this purpose, the subject of the invention is a headlamp for a signaling light of a motor vehicle, comprising an ice cream, at least the upper end of which is capable of being secured to the housing of this headlight by means of connection, characterized in that the ice, on its end portion connected to the housing, comprises an element masking at least the connecting means, seen from the outside of this projector.

  • cet élément masquant s'étend sensiblement perpendiculairement au plan de l'extrémité de la glace,
  • l'extrémité de la glace pénètre dans une gorge aménagée à l'extrémité du boîtier en vis à vis, cette gorge présentant la forme d'un U incliné à 90° avec deux bras espacés sensiblement parallèles et horizontaux,
  • le moyen de liaison entre l'extrémité de la glace et la gorge est une couche de colle ajoutée à l'intérieur de la gorge,
  • l'élément masquant de la glace du projecteur sert aussi de moyen de limitation du débordement du moyen de liaison hors du contact entre la glace et le boîtier,
  • l'élément masquant est venu de matière avec la glace du projecteur,
  • le côté de l'élément masquant tourné vers le boîtier présente des moyens rendant opaque la vision de la liaison, vue de l'extérieur du projecteur,
  • le côté de l'élément masquant opposé au boîtier présente des moyens réfléchissant la lumière.
According to additional features of the present invention:
  • the masking element is a part of the ice projecting transversely thereto and disposed near its end connected to the housing,
  • this masking element extends substantially perpendicular to the plane of the end of the ice,
  • the end of the ice enters a groove arranged at the end of the housing opposite, this groove having the shape of a U inclined at 90 ° with two arms spaced substantially parallel and horizontal,
  • the connecting means between the end of the ice and the groove is a layer of glue added inside the groove,
  • the masking element of the projector glass also serves as a means of limiting the overflow of the connecting means from the contact between the window and the housing,
  • the masking element came from material with the projector's mirror,
  • the side of the hiding element turned towards the housing has means making opaque the vision of the connection, seen from the outside of the projector,
  • the side of the masking element opposite to the housing has means reflecting light.

L'invention concerne également un véhicule automobile, caractérisé en ce qu'il comprend au moins un tel projecteur.The invention also relates to a motor vehicle, characterized in that it comprises at least one such projector.

L'effet technique obtenu par la présente invention est de masquer la liaison entre glace et boîtier du projecteur par un élément masquant porté par la glace. Une continuité de glace est alors visible de l'extérieur à travers le jeu périphérique du projecteur tandis que ni le moyen de liaison ni la partie du boîtier assurant la liaison avec la glace ne sont alors visibles de l'extérieur.The technical effect obtained by the present invention is to hide the connection between ice and projector housing by a masking element carried by the ice. A continuity of ice is then visible from the outside through the peripheral game of the projector while neither the connecting means nor the part of the housing ensuring the connection with the ice are then visible from the outside.

De plus, cet élément masquant permet également de mieux maîtriser le débordement éventuel du moyen de liaison en empêchant celui-ci de venir déborder dans la zone visible de l'extérieur.In addition, this masking element also makes it possible to better control the possible overflow of the connecting means by preventing the latter from overflowing into the visible zone from the outside.

La figure 1 a déjà été détaillée dans la partie introductive de la présente description.The figure 1 has already been detailed in the introductory part of this description.

La figure 2 montre un projecteur selon la présente invention. Le principe de liaison entre la glace 1 et le boîtier 2 est le même que celui-ci montré à la figure 1 et connu de l'état de la technique.The figure 2 shows a projector according to the present invention. The principle of connection between the ice 1 and the housing 2 is the same as the one shown in FIG. figure 1 and known from the state of the art.

Selon la présente invention, ce projecteur présente une glace 1 qui porte vers son extrémité 1a, en vis-à-vis de la gorge 2a du boîtier 2, un élément 5 faisant saillie transversalement par rapport à la glace 1. Avantageusement, cet élément 5 est disposé à proximité de l'extrémité 1a de la glace dépassant de la gorge 2a du boîtier 2.According to the present invention, this projector has an ice 1 which carries towards its end 1a, vis-à-vis the groove 2a of the housing 2, an element 5 protruding transversely relative to the ice 1. Advantageously, this element 5 is disposed near the end 1a of the ice protruding from the groove 2a of the housing 2.

Cet élément 5 faisant saillie de la glace 1 peut être, avantageusement, venu de matière avec la glace 1. La glace peut être moulée de telle sorte que la glace 1 et l'élément 5 sont monobloc. L'élément 5 est, avantageusement, disposé en s'étendant verticalement sur la partie supérieure de la glace 1 en position de liaison de la glace 1 et du boîtier 2 et cache, en vue de l'extérieur, la liaison entre cette glace 1 et ce boîtier 2.This element 5 protruding from the ice 1 may advantageously be integral with the ice 1. The ice may be molded so that the ice 1 and the element 5 are in one piece. The element 5 is advantageously arranged by extending vertically on the upper part of the window 1 in the position of connection of the window 1 and the housing 2 and conceals, in view of the exterior, the connection between this window 1 and this case 2.

Comme précédemment décrit pour l'état de la technique, la liaison entre glace 1 du projecteur et boîtier 2 peut être réalisée par l'introduction de l'extrémité de la glace 1 entre la gorge 2a disposée à l'extrémité en vis à vis du boîtier 2 avec interposition d'un moyen de liaison entre cette extrémité 1a de la glace 1 et les deux bras de la gorge 2a, ce moyen de liaison pouvant être avantageusement une couche de colle 3. Il est cependant à signaler que d'autres moyens de liaison sont possibles, par exemple du mastic ou un joint d'étanchéité. Dans ce dernier cas, des moyens de liaison additionnels sont requis.As previously described for the state of the art, the connection between ice 1 of the projector and 2 can be achieved by the introduction of the end of the ice 1 between the groove 2a disposed at the end facing the housing 2 with the interposition of a connecting means between the end 1a of the ice 1 and the two arms of the groove 2a, the connecting means may be advantageously a layer of adhesive 3. It should however be noted that other connecting means are possible, for example putty or a seal. In the latter case, additional connecting means are required.

Pour que cet élément 5 en saillie soit le plus efficace possible, celui-ci doit s'étendre le long de toute la périphérie de la glace 1 juste au niveau de la gorge 2a du boîtier 2. C'est lors de l'assemblage de la glace 1 dans la gorge 2a que l'élément en saillie 5 permet de masquer la vision de la liaison entre glace 1 et boîtier 2 quand celle-ci est vue de l'extérieur.In order for this protruding element to be as effective as possible, it must extend along the entire periphery of the window 1 just at the groove 2a of the housing 2. It is during the assembly of the ice 1 in the groove 2a that the projecting element 5 can hide the vision of the connection between ice 1 and 2 housing when it is viewed from the outside.

Cet élément en saillie 5 masque au moins le moyen de liaison entre glace 1 et boîtier 2 mais il peut aussi, avantageusement masquer toute la partie du boîtier 2 qui peut être visible d'une vue de l'extérieur du projecteur. Cette partie masquée peut comprendre, par exemple, toute la gorge 2a ou une partie de celle-ci en plus du moyen de liaison proprement dit, constitué par la colle, le mastic ou un joint.This projecting element 5 masks at least the connection means between the ice 1 and the housing 2, but it can also, advantageously, mask the entire portion of the housing 2 which can be seen from a view from outside the projector. This masked part may comprise, for example, the entire groove 2a or a part thereof in addition to the actual bonding means, consisting of glue, putty or a seal.

La figure 3 montre un rôle auxiliaire de cet élément 5 faisant saillie de la glace 1. Dans le cas d'un débordement du moyen de liaison 3 ajouté entre glace 1 et boîtier 2, ce moyen étant préférentiellement de la colle, une partie 3a de celle-ci sort de la gorge 2a et s'écoule vers l'extérieur, l'élément 5 faisant saillie de la glace 1 peut alors faire obstacle à l'écoulement de la colle hors de la gorge, étant entendu qu'il doit alors être placé à faible distance de l'extrémité extérieure de cette gorge 2a. Il est possible de prévoir sur la glace 1 un autre élément, symétrique au premier par rapport au plan de la glace 1 et faisant saillie vers le bas, cet élément servant simplement d'arrêt du débordement de colle sur le côté inférieur de la glace 1.The figure 3 shows an auxiliary role of this element 5 projecting from the ice 1. In the case of an overflow of the connecting means 3 added between the ice 1 and the housing 2, this means being preferably glue, a part 3a thereof out of the groove 2a and flows outwardly, the element 5 projecting from the ice 1 can then impede the flow of glue out of the groove, it being understood that it must then be placed short distance from the outer end of this groove 2a. It is possible to provide on the ice 1 another element, symmetrical to the first relative to the plane of the ice 1 and projecting downwards, this element serving merely to stop the overflow of glue on the lower side of the ice 1.

Ainsi, dans le cas de la figure 3, en plus de masquer la vision de la liaison entre glace 1 et boîtier 2, l'élément 5 permet aussi de contenir en le limitant le débordement 3a de colle de la gorge 2a.So, in the case of the figure 3 , in addition to masking the vision of the connection between the ice 1 and the housing 2, the element 5 also makes it possible to contain, by limiting it, the overflow 3a of glue from the groove 2a.

Les figures 4 et 5 montrent principalement une forme de réalisation de l'élément 5 en saillie de la glace 1 permettant d'améliorer le masquage de la liaison entre glace 1 et boîtier 2. Pour améliorer le masquage de cette liaison, l'élément en saillie 5 peut, avantageusement, comporter des stries ou un gros grainage 6, ce qui le rend plus opaque pour la vision de la liaison de l'extérieur. Ces stries et cette zone de gros grainage 6 sont disposées sur toute la périphérie de l'élément 5 en saillie faisant face à la gorge 2a du boîtier 2.The figures 4 and 5 mainly show an embodiment of the element 5 projecting from the ice 1 to improve the masking of the connection between the ice 1 and the housing 2. To improve the masking of this connection, the projecting element 5 can advantageously , have striations or a large graining 6, which makes it more opaque for the vision of the connection from the outside. These ridges and this coarse graining zone 6 are disposed over the entire periphery of the protruding element 5 facing the groove 2a of the housing 2.

En alternative, le côté de l'élément en saillie 5, opposé au boîtier, peut présenter des moyens réfléchissant la lumière, par exemple en un métal brillant comme l'aluminium. Ceci a pour avantage de lui conférer une apparence voisine de celui du reste de la glace 1 et donc d'harmoniser l'aspect rendu par la glace 1 et cet élément en saillie 5.Alternatively, the side of the projecting element 5, opposite to the housing, may have light reflecting means, for example a shiny metal such as aluminum. This has the advantage of giving it a similar appearance to that of the rest of the ice 1 and thus to harmonize the appearance made by the ice 1 and this projecting element 5.

Il convient de remarquer que l'élément 5 en saillie s'étend préférentiellement sur toute la périphérie de la glace 1 et qu'il n'est pas localisé sur seulement une partie de la glace 1.It should be noted that the projecting element 5 preferably extends over the entire periphery of the ice 1 and that it is not located on only a part of the ice 1.

Le principal avantage de la solution est d'éviter le rajout d'un joint périphérique coûteux et difficile de positionnement. La solution proposée par la présente invention permet ainsi un gain de temps lors du montage de la glace, l'élément en saillie étant monobloc avec cette glace, en étant par exemple ajouté à celle-ci par surmoulage et non sous la forme d'une pièce rajoutée.The main advantage of the solution is to avoid the addition of an expensive peripheral seal and difficult positioning. The solution proposed by the present invention thus saves time when mounting the ice, the projecting element being integral with this ice, being for example added thereto by overmolding and not in the form of a room added.

L'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.The invention is not limited to the embodiment described and illustrated which has been given by way of example.
