Abstract

The lighting device includes the headlamp or indicating lamp (6) which is fitted into a lampholder (4) installed in an aperture (3) in the plane wall of the housing (2). The rigid hook (14) on the inside of the housing engages with a paraxial slotted tab (16) on the reflector (10). The tab is flexible in a radial direction towards the interior of the reflector. The diameter (M) of the lampholder at the level of the hook and slot is such that the tab can be flexed inwards sufficiently to slide over the curved surface of the hook, which may be flexible in the opposite direction.

Description

L'invention concerne les dispositifs d'éclairage et/ou de signalisation pour véhicule automobile.The invention relates to lighting and / or signaling devices for motor vehicles.

On connaît un feu de signalisation pour véhicule automobile, comportant un support, un porte-lampe fixé au support, une lampe fixée au porte-lampe, et un réflecteur fixé au support. La configuration des pièces nécessite que le feu soit assemblé en montant le réflecteur sur le support, puis le porte-lampe sur le support. Cependant, pour certains modèles de feu, compte tenu de contraintes de fabrication et d'acheminement des pièces jusqu'à la chaîne de montage, les pièces arrivent sur la chaîne dans un ordre ne correspondant pas à l'ordre de montage précité. L'assemblage s'en trouve ralenti, ce qui augmente les prix de revient. Ainsi, si la fabrication du réflecteur est assurée par le constructeur, et celle du support et du porte-lampe est assurée par un sous-traitant, celui-ci ne peut pas monter le porte-lampe sur le support avant livraison au constructeur. Il est donc préférable d'avoir un dispositif d'éclairage et/ou de signalisation permettant d'assembler les pièces dans un ordre différent de l'ordre précité.A signal light for a motor vehicle is known, comprising a support, a lamp holder fixed to the support, a lamp fixed to the lamp holder, and a reflector fixed to the support. The configuration of the parts requires that the light be assembled by mounting the reflector on the support, then the lamp holder on the support. However, for certain models of fire, given the constraints of manufacturing and routing of the parts to the assembly line, the parts arrive on the chain in an order that does not correspond to the above-mentioned assembly order. Assembly is slowed down, which increases the cost price. Thus, if the manufacture of the reflector is provided by the manufacturer, and that of the support and the lamp holder is provided by a subcontractor, the latter cannot mount the lamp holder on the support before delivery to the manufacturer. It is therefore preferable to have a lighting and / or signaling device enabling the parts to be assembled in an order different from the above order.

Le document FR-A-2 304 025 décrit un dispositif d'éclairage pour véhicule automobile, comportant un support, un porte-lampe fixé dans un logement du support, une lampe fixée au porte-lampe et un réflecteur fixé au support par encliquetage. A cette fin, le réflecteur porte des crochets d'encliquetage adaptés à pénétrer dans des orifices du support au voisinage du culot de la lampe pour fixer le réflecteur au support. En vue de permettre le montage du réflecteur après la mise en place de la lampe, ces crochets s'étendent radialement à grande distance du culot de la lampe. Il s'ensuit que la surface réfléchissante du réflecteur s'étend en arrière à distance du bulbe de la lampe et radialement à distance du porte-lampe. Par conséquent, une quantité de lumière significative s'échappe entre le culot et le réflecteur vers l'arrière du dispositif. Le rendement optique est donc faible. De plus, l'espace entre le culot et le réflecteur est visible depuis l'extérieur du feu, ce qui nuit à l'esthétique du véhicule.Document FR-A-2 304 025 describes a lighting device for a motor vehicle, comprising a support, a lamp holder fixed in a housing of the support, a lamp fixed to the lamp holder and a reflector fixed to the support by snap-fastening. To this end, the reflector carries snap hooks adapted to penetrate holes in the support in the vicinity of the lamp base to fix the reflector to the support. In order to allow the mounting of the reflector after the fitting of the lamp, these hooks extend radially at a great distance from the base of the lamp. It follows that the reflective surface of the reflector extends backwards at a distance from the bulb of the lamp and radially away from the lamp holder. Consequently, a significant amount of light escapes between the base and the reflector towards the rear of the device. The optical efficiency is therefore low. In addition, the space between the base and the reflector is visible from outside the light, which affects the aesthetics of the vehicle.

Un but de l'invention est de fournir un dispositif d'éclairage et/ou de signalisation permettant de monter l'élément de garniture après montage de la lampe sur le dispositif, tout en fournissant un bon rendement optique et en donnant une esthétique satisfaisante au feu.An object of the invention is to provide a lighting and / or signaling device making it possible to mount the trim element after mounting the lamp on the device, while providing good optical performance and giving a satisfactory aesthetic to the fire.

En vue de la réalisation de ce but, on prévoit selon l'invention un dispositif d'éclairage et/ou de signalisation selon la revendication 1.With a view to achieving this aim, a lighting and / or signaling device according to claim 1 is provided according to the invention.

Ainsi, l'élément de garniture peut être fixé au support avec sa surface s'étendant très près du bulbe de la lampe de sorte que la plupart des rayons émis par la lampe vers l'arrière sont arrêtés par l'élément de garniture. De plus, aucun espace n'est plus visible entre la lampe et l'élément de garniture depuis l'extérieur du véhicule. On améliore donc le rendement optique et l'aspect du dispositif. Ce dispositif autorise en outre le montage de l'élément de garniture sur le support après montage de la lampe sur celui-ci. De plus, il évite d'avoir à donner une longueur importante aux organes d'encliquetage de l'élément de garniture (ce qui compliquerait la fabrication et la forme de l'élément de garniture et serait coûteux).Thus, the trim element can be fixed to the support with its surface extending very close to the bulb of the lamp so that most of the rays emitted by the lamp towards the rear are stopped by the trim element. In addition, no space is more visible between the lamp and the trim element from outside the vehicle. The optical efficiency and the appearance of the device are therefore improved. This device also allows mounting of the trim element on the support after mounting the lamp on it. In addition, it avoids having to give a significant length to the latching members of the trim element (which would complicate the manufacture and the shape of the trim element and would be expensive).

D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description suivante d'un mode de réalisation préféré et d'une variante, donnée à titre d'exemple non limitatif. Aux dessins annexés :

  • la figure 1 est une vue partielle en coupe axiale d'un dispositif selon l'invention ;
  • la figure 2 est une vue analogue à la figure 1 montrant le montage du réflecteur ; et
  • la figure 3 est une vue analogue à la figure 2 montrant une variante de réalisation.
Other characteristics and advantages of the invention will become apparent on reading the following description of a preferred embodiment and of a variant, given by way of nonlimiting example. In the accompanying drawings:
  • Figure 1 is a partial view in axial section of a device according to the invention;
  • Figure 2 is a view similar to Figure 1 showing the mounting of the reflector; and
  • Figure 3 is a view similar to Figure 2 showing an alternative embodiment.

En référence aux figures 1 et 2, le dispositif d'éclairage et de signalisation pour véhicule automobile comporte un projecteur et un feu de signalisation qui est ici un feu clignotant.Referring to Figures 1 and 2, the lighting and signaling device for a motor vehicle comprises a headlamp and a signaling light which is here a flashing light.

Le dispositif comporte un support ou boîtier 2 comportant une paroi plane présentant une ouverture 3 qui constitue un logement de réception pour un porte-lampe. Le dispositif comporte un porte-lampe 4 fixé au support dans le logement 3, par exemple grâce à des moyens de fixation par verrouillage quart de tour. Le feu comporte une lampe 6 sous la forme d'une ampoule à section circulaire ayant un axe 8 définissant l'axe du feu. La lampe est fixée par son culot au porte-lampe. Le dispositif comporte en outre un élément de garniture sous la forme d'un réflecteur ou surface optique 10 fixé au support. Le réflecteur comporte un évidement ou ajour 12 d'axe 8 adjacent au porte-lampe et au culot de la lampe, et s'étendant en regard de ceux-ci. L'évidement 12 du réflecteur a des dimensions transversales à l'axe 8, dont l'une L est illustrée sur la figure 1, qui sont supérieures aux dimensions transversales de la lampe, c'est-à-dire en l'espèce supérieures au plus grand diamètre D de la lampe.The device comprises a support or housing 2 comprising a flat wall having an opening 3 which constitutes a receiving housing for a lamp holder. The device comprises a lamp holder 4 fixed to the support in the housing 3, for example by means of fixing by quarter-turn locking. The fire comprises a lamp 6 in the form of a circular section bulb having an axis 8 defining the axis of the fire. The lamp is fixed by its base to the lamp holder. The device further comprises a trim element in the form of a reflector or optical surface 10 fixed to the support. The reflector comprises a recess or aperture 12 of axis 8 adjacent to the lamp holder and to the base of the lamp, and extending opposite them. The recess 12 of the reflector has dimensions transverse to the axis 8, one of which L is illustrated in FIG. 1, which are greater than the transverse dimensions of the lamp, that is to say in this case greater at the largest diameter D of the lamp.

Le support comporte des organes d'encliquetage sous la forme de crochets rigides 14 s'étendant en saillie de la paroi plane du support et présentant chacun un ergot dirigé vers l'axe 8 et le porte-lampe. Le réflecteur comporte des organes d'encliquetage sous la forme de pattes 16 parallèles à l'axe 8. Ces pattes 16 sont flexibles suivant une direction transversale à l'axe en direction de celui-ci et du porte-lampe, à savoir vers l'intérieur du réflecteur. Elles présentent chacune un orifice adapté à recevoir l'un des ergots. Les crochets 14 et les pattes 16 coopèrent mutuellement et respectivement pour la fixation par encliquetage du réflecteur au support, le montage étant effectué en approchant le réflecteur 10 du support 2 selon un mouvement suivant l'axe 8. Chaque ergot présente une face courbe convexe ou inclinée par rapport à la direction radiale à l'axe 8. Cette face constitue une rampe pour la patte 16 associée lors du montage du réflecteur 10 sur le support 2, la rampe forçant la patte 16 à se fléchir en direction du porte-lampe au passage de l'ergot, comme le montre la figure 2. Cet effet de rampe provoque le centrage du réflecteur lors de son montage sur le support. Ce montage est ainsi facilité. Dans le document FR-A-2 304 025 précité, le montage du réflecteur est rendu plus difficile par le fait que l'opérateur doit lui-même convenablement positionner le réflecteur en fonction des orifices du support destinés à recevoir les ergots.The support comprises latching members in the form of rigid hooks 14 projecting from the flat wall of the support and each having a lug directed towards the axis 8 and the lamp holder. The reflector comprises latching members in the form of lugs 16 parallel to the axis 8. These lugs 16 are flexible in a direction transverse to the axis in direction of the latter and of the lamp holder, namely towards the interior of the reflector. They each have an orifice adapted to receive one of the lugs. The hooks 14 and the lugs 16 cooperate mutually and respectively for the snap fastening of the reflector to the support, the assembly being carried out by bringing the reflector 10 from the support 2 according to a movement along the axis 8. Each lug has a convex curved face or inclined with respect to the radial direction to the axis 8. This face constitutes a ramp for the tab 16 associated during mounting of the reflector 10 on the support 2, the ramp forcing the tab 16 to bend in the direction of the lamp holder at passage of the lug, as shown in Figure 2. This ramp effect causes the reflector to be centered when it is mounted on the support. This assembly is thus facilitated. In the aforementioned document FR-A-2,304,025, the mounting of the reflector is made more difficult by the fact that the operator must himself suitably position the reflector as a function of the orifices of the support intended to receive the pins.

Le porte-lampe 4 présente une zone 18 s'étendant en regard des crochets 14 du support et des pattes 16 du réflecteur. Suivant la direction radiale de flexion des pattes, à savoir suivant une direction perpendiculaire à l'axe 8, cette zone a une dimension M suffisamment réduite pour permettre la flexion de chaque patte 16 du réflecteur au passage du crochet 14 du support.The lamp holder 4 has a zone 18 extending opposite the hooks 14 of the support and the lugs 16 of the reflector. In the radial direction of flexion of the legs, namely in a direction perpendicular to the axis 8, this area has a dimension M sufficiently small to allow the flexing of each leg 16 of the reflector when the hook 14 of the support passes.

Une fois monté, le réflecteur 10 s'étend suivant une direction radiale entre les crochets 14 du support et le porte-lampe 4. Il s'étend en regard du porte-lampe 4 et de la paroi du support 2 à distance de celle-ci.Once mounted, the reflector 10 extends in a radial direction between the hooks 14 of the support and the lamp holder 4. It extends opposite the lamp holder 4 and the wall of the support 2 at a distance from it. this.

L'assemblage du dispositif comprend les étapes suivantes. On monte la lampe 6 sur le porte-lampe 4, puis le porte-lampe 4 sur le support 2. Ensuite, on monte le réflecteur 10 sur le support 2. Pour cela, on fait passer la lampe 6 dans l'évidement 12, ce qui est rendu possible par la condition dimensionnelle précitée. On encliquette le réflecteur 10 sur les crochets 14 du support grâce à la flexibilité des pattes 16.The assembly of the device comprises the following steps. The lamp 6 is mounted on the lamp holder 4, then the lamp holder 4 on the support 2. Then, the reflector 10 is mounted on the support 2. For this, we pass the lamp 6 in the recess 12, which is made possible by the aforementioned dimensional condition. The reflector 10 is snapped onto the hooks 14 of the support thanks to the flexibility of the lugs 16.

En référence à la figure 3, dans une variante de réalisation, les pattes 16 du réflecteur 10 sont rigides et les crochets 14 du support 2 sont flexibles suivant une direction radiale à l'axe 8 en sens opposé au porte-lampe 4, à savoir vers l'extérieur du réflecteur 10. La face des ergots formant rampe provoque ainsi la flexion des crochets 14 au passage des pattes 16 lors du montage du réflecteur 10 sur le support 2. Dans cette variante, la dimension transversale M de la zone 18 du porte-lampe 4 s'étendant en regard des pattes 16 peut être plus importante que sur la figure 1. Cette dimension peut être juste inférieure aux dimensions transversales de l'évidement.Referring to Figure 3, in an alternative embodiment, the legs 16 of the reflector 10 are rigid and the hooks 14 of the support 2 are flexible in a direction radial to the axis 8 in the opposite direction to the lamp holder 4, namely towards the outside of the reflector 10. The face of the lugs forming a ramp thus causes the hooks 14 to flex when the tabs 16 pass when the reflector 10 is mounted on the support 2. In this variant, the transverse dimension M of the zone 18 of the lamp holder 4 extending opposite the legs 16 may be greater than in FIG. 1. This dimension may be just less than the transverse dimensions of the recess.

Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci. Ainsi, les pattes pourront être portées par le support 2 et les crochets par le réflecteur 10. Le dispositif pourra comporter plusieurs lampes 6 de signalisation fixées au porte-lampes 2. L'évidement pourra alors avoir une forme allongée.Le dispositif pourra comprendre un élément de garniture différent d'un réflecteur. Cet élément de garniture sera par exemple une plaque optique réfringente.Of course, many modifications can be made to the invention without departing from the scope thereof. Thus, the legs may be carried by the support 2 and the hooks by the reflector 10. The device may include several signal lamps 6 attached to the lamp holder 2. The recess may then have an elongated shape. The device may include a trim element different from a reflector. This packing element will be for example a refractive optical plate.
