Description

L'invention concerne un porte-lampe pour projecteur ou feu, notamment pour véhicule automobile.The invention relates to a lamp holder for a headlamp or light, in particular for a motor vehicle.

Dans la suite de la description, on se référera par commodité à l'application à un projecteur, mais celle-ci n'est nullement limitative dans la mesure où, comme on le comprendra, l'invention n'est pas liée à la fonction de l'organe d'éclairage et peut donc être mise en oeuvre dans des applications très variées.In the following description, reference is made for convenience to the application to a projector, but the latter is in no way limiting in so far as, as will be understood, the invention is not linked to the function of the lighting member and can therefore be implemented in a wide variety of applications.

L'invention s'applique tout particulièrement au cas des projecteurs situés en un emplacement tel qu'il ne subsiste en partie postérieure du réflecteur qu'un très faible dégagement pour le retrait et la remise en place de la lampe du projecteur. Cette configuration se rencontre de plus en plus souvent dans les véhicules modernes, où l'on dispose de façon très compacte les différents organes dans le compartiment moteur.The invention applies very particularly to the case of projectors situated in a location such that only a very small clearance remains in the rear part of the reflector for removing and replacing the lamp of the projector. This configuration is found more and more often in modern vehicles, where the various components in the engine compartment are very compactly arranged.

Du fait de ce faible dégagement, un changement de lampe devient très délicat, avec les risques corrélatifs de laisser échapper la lampe au moment du montage, de mal la fixer, etc.Because of this low clearance, changing the lamp becomes very delicate, with the correlative risks of letting the lamp escape during assembly, of fixing it incorrectly, etc.

L'invention propose de remédier à cette difficulté en prévoyant un projecteur comportant un réflecteur avec une encoche radiale permettant l'introduction d'une lampe dans le réflecteur depuis l'extérieur essentiellement par un mouvement de déplacement radial par rapport au réflecteur, l'ensemble lampe et porte-lampe s'étendant alors axialement, de part et d'autre d'une ouverture centrale du réflecteur, pour partie à l'intérieur du réflecteur et pour partie à l'extérieur de celui-ci. Le porte-lampe comporte alors : un corps support de lampe, propre à recevoir une lampe et un organe de connexion électrique à celle-ci ; un bras de manoeuvre, relié à ce corps support et s'étendant essentiellement radialement par rapport à l'axe du réflecteur ; des moyens de centrage axial du corps support sur le réflecteur ; des moyens de guidage du corps support par rapport au réflecteur, depuis une position d'insertion jusqu'à une position montée, le passage de la position montée à la position d'insertion étant opérée par une rotation d'une fraction de tour du corps support par rapport au réflecteur ; et des moyens de verrouillage en position montée du corps support sur le réflecteur.The invention proposes to overcome this difficulty by providing a headlamp comprising a reflector with a radial notch allowing the introduction of a lamp into the reflector from the outside essentially by a movement of radial displacement relative to the reflector, the assembly lamp and lamp holder then extending axially, on either side of a central opening of the reflector, partly inside the reflector and partly outside the latter. The lamp holder then comprises: a lamp support body, suitable for receiving a lamp and a member for electrical connection thereto; an operating arm, connected to this support body and extending essentially radially with respect to the axis of the reflector; means for axial centering of the support body on the reflector ; means for guiding the support body relative to the reflector, from an insertion position to a mounted position, the passage from the mounted position to the insertion position being effected by a rotation of the body by a fraction of a turn support relative to the reflector; and locking means in the mounted position of the support body on the reflector.

Les moyens de centrage axial peuvent notamment comporter des surfaces d'appui périphériques de l'ensemble lampe et porte-lampe, qui coopèrent avec des surfaces de portée homologues de l'ouverture du réflecteur.The axial centering means may in particular comprise peripheral bearing surfaces of the lamp and lamp holder assembly, which cooperate with bearing surfaces homologous to the opening of the reflector.

Les moyens de guidage peuvent notamment comporter une collerette du corps support qui coopère avec une pièce de retenue solidaire du réflecteur empêchant tout déplacement axial, la pièce de retenue comportant alors avantageusement des lames élastiques sollicitant axialement l'ensemble lampe et porte-lampe contre le réflecteur.The guide means may in particular comprise a flange of the support body which cooperates with a retaining piece integral with the reflector preventing any axial displacement, the retaining piece then advantageously comprising elastic blades axially urging the lamp and lamp holder assembly against the reflector .

Les moyens de verrouillage en position montée peuvent notamment comporter un bossage solidaire du corps support et coopérant avec une lame élastique homologue solidaire du réflecteur.The locking means in the mounted position may in particular comprise a boss secured to the support body and cooperating with a homologous elastic blade secured to the reflector.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée ci-dessous d'un exemple de réalisation, faite en référence aux dessins annexés.Other characteristics and advantages of the invention will appear on reading the detailed description below of an exemplary embodiment, made with reference to the accompanying drawings.

La figure 1 est un dessin schématique, vu de trois-quarts arrière, d'un ensemble réflecteur, porte-lampe et lampe selon l'invention, montrant la manière dont le porte-lampe est introduit dans le réflecteur et monté sur celui-ci.Figure 1 is a schematic drawing, seen from three-quarters rear, of a reflector, lamp holder and lamp assembly according to the invention, showing the manner in which the lamp holder is inserted into and mounted on the reflector .

La figure 2 est une coupe en élévation, selon la ligne brisée II-II de la figure 4, de l'ensemble porte-lampe et lampe placé dans le réflecteur, dans la position de montage final.Figure 2 is an elevational section along the broken line II-II of Figure 4 of the lamp holder assembly and lamp placed in the reflector, in the final mounting position.

La figure 3 est une vue de face du porte-lampe seul, montrant le bras de manoeuvre et les moyens de centrage de la lampe.Figure 3 is a front view of the lamp holder alone, showing the operating arm and the lamp centering means.

La figure 4 est une vue arrière de ce même porte-lampe monté sur le réflecteur, le dessin en trait plein correspondant à la position de montage final du porte-lampe et le dessin en trait mixte correspondant à la position d'insertion de ce porte-lampe dans l'encoche du projecteur.Figure 4 is a rear view of the same lamp holder mounted on the reflector, the solid line drawing corresponding to the final mounting position of the lamp holder and the phantom drawing corresponding to the insertion position of this door -lamp in the notch of the projector.

La figure 5 est une vue arrière du réflecteur seul, dans la région de l'ouverture centrale, montrant notamment les faces d'appui recevant la lampe et le porte-lampe.Figure 5 is a rear view of the reflector alone, in the region of the central opening, showing in particular the bearing faces receiving the lamp and the lamp holder.

Sur la figure 1, on a représenté schématiquement le projecteur configuré selon l'invention, désigné de façon générale par la référence numérique 1. Celui-ci comprend essentiellement, outre divers éléments que l'on ne décrira pas car ils ne contribuent pas à la mise en oeuvre de l'invention (organes de montage du projecteur sur la carrosserie, glace de fermeture, etc.) un réflecteur ou miroir 2 recevant un porte-lampe 3 muni de sa lampe 4 (ici et dans la suite, on supposera toujours que le porte-lampe 3 a été auparavant équipé de sa lampe 4, cette opération étant préalable au montage du porte-lampe sur le réflecteur 2 du projecteur).In FIG. 1, the headlamp configured according to the invention is shown diagrammatically, generally designated by the reference numeral 1. This essentially comprises, in addition to various elements which will not be described since they do not contribute to the implementation of the invention (means of mounting the projector on the bodywork, closing glass, etc.) a reflector or mirror 2 receiving a lamp holder 3 provided with its lamp 4 (here and in the following, we will always assume that the lamp holder 3 was previously equipped with its lamp 4, this operation being prior to mounting the lamp holder on the reflector 2 of the projector).

L'ensemble porte-lampe et lampe est destiné à être monté dans une ouverture centrale 5 formée dans l'axe du réflecteur, par exemple dans l'axe du paraboloïde dans le cas, le plus fréquent, d'un projecteur à réflecteur parabolique.The lamp holder and lamp assembly is intended to be mounted in a central opening 5 formed in the axis of the reflector, for example in the axis of the paraboloid in the most frequent case of a projector with parabolic reflector.

De façon caractéristique de l'invention, le porte-lampe est introduit par une encoche 6 formée à partir de l'ouverture 5 et qui s'étend approximativement par exemple suivant l'intersection de la surface du réflecteur avec un plan radial vertical ou légèrement incliné. Dans le mode de réalisation illustré, on a prévu, pour des considérations pratiques, une légère inclinaison α (figure 4) de l'ordre de 9°, mais sans aucun caractère limitatif.Characteristically of the invention, the lamp holder is introduced by a notch 6 formed from the opening 5 and which extends approximately for example along the intersection of the surface of the reflector with a vertical or slightly inclined radial plane. In the illustrated embodiment, provision has been made, for practical considerations, for a slight inclination α (FIG. 4) of the order of 9 °, but without any limiting character.

L'encoche 6 est borgne ; elle se prolonge en direction axiale vers l'avant du projecteur sur une longueur correspondant approximativement à la longueur de la lampe 4. Cette dimension dépend en fait de considérations pratiques et l'on comprendra que, si l'on dispose d'un léger dégagement en partie postérieure du réflecteur, on peut prévoir une encoche plus courte en direction axiale.The notch 6 is blind; it extends in an axial direction towards the front of the projector over a length corresponding approximately to the length of the lamp 4. This dimension in fact depends on practical considerations and it will be understood that, if there is a slight clearance in the rear part of the reflector, it is possible to provide a shorter notch in the axial direction.

L'encoche 6 permet l'insertion de la lampe essentiellement par un mouvement de translation verticale de descente (flèche 7 sur la figure 1) suivi, après mise en place de l'ensemble à l'arrière du projecteur, d'un mouvement de rotation (flèche 8) sur une fraction de tour, pour verrouiller en place le porte-lampe dans l'ouverture 5.The notch 6 allows the insertion of the lamp essentially by a vertical downward translational movement (arrow 7 in FIG. 1) followed, after positioning of the assembly at the rear of the projector, by a movement of rotation (arrow 8) on a fraction of a turn, to lock the lamp holder in place in the opening 5.

Le porte-lampe 3 comporte essentiellement un corps support de lampe 9 recevant la lampe d'une manière en elle-même connue (par exemple par enfichage de contacts, comme on peut le voir sur la coupe de la figure 2) et pourvu en partie arrière de moyens de connexion électrique à la lampe, qui peuvent être soit un connecteur enfichable soit, comme représenté en 10 sur la figure 1, des fils conducteurs surmoulés avec le corps du porte-lampe et directement issus d'un faisceau de câbles.The lamp holder 3 essentially comprises a lamp support body 9 receiving the lamp in a manner known per se (for example by plugging in of contacts, as can be seen in the section of FIG. 2) and provided in part rear of electrical connection means to the lamp, which can be either a plug connector or, as shown at 10 in FIG. 1, conductive wires overmolded with the body of the lamp holder and directly coming from a bundle of cables.

Le porte-lampe 3 comporte une collerette 11 dont on expliquera plus loin le rôle ainsi qu'une tige ou bras de manoeuvre allongé 12 permettant à l'utilisateur de réaliser le mouvement de rotation (de la flèche 8) lorsque le porte-lampe est placé dans l'ouverture 5 du réflecteur 2, et ceci en dépit du faible dégagement à l'arrière du réflecteur.The lamp holder 3 comprises a flange 11, the role of which will be explained below, as well as an elongated rod or operating arm 12 allowing the user to perform the rotational movement (of arrow 8) when the lamp holder is placed in the opening 5 of the reflector 2, and this despite the small clearance at the rear of the reflector.

La collerette 11 a une forme approximativement circulaire et plate et vient se glisser entre, d'une part, la face arrière du réflecteur 2 en périphérie de l'ouverture 5 et, d'autre part, une pièce de retenue 13 (figure 2 et 4) qui est de préférence une pièce rapportée métallique fixée au projecteur en 14 (figure 2 et 5) aux moyens de vis 15.The flange 11 has an approximately circular and flat shape and slides between, on the one hand, the rear face of the reflector 2 at the periphery of the opening 5 and, on the other hand, a retaining part 13 (FIG. 2 and 4) which is preferably a metal insert fixed to the projector at 14 (FIGS. 2 and 5) by means of screws 15.

La pièce de retenue 13 comporte des surfaces 16 (figure 4) venant maintenir la région 17 de la collerette 11 pincée entre cette surface 16 et la face arrière en vis-à-vis du réflecteur, autour de l'ouverture 5. On empêche ainsi le déplacement axial du porte-lampe, tout en autorisant son introduction par le haut puis son pivotement autour de l'axe central ; en d'autres termes, la pièce de retenue 13 agit à la manière d'un réceptacle pour le porte-lampe, celui-ci étant guidé radialement et axialement à l'intérieur de ce réceptacle par la collerette.The retaining piece 13 has surfaces 16 (FIG. 4) which hold the region 17 of the flange 11 pinched between this surface 16 and the rear face opposite the reflector, around the opening 5. This thus prevents axial displacement of the lamp holder, while allowing it to be inserted from above and then pivoted about the central axis; in other words, the retaining part 13 acts in the manner of a receptacle for the lamp holder, the latter being guided radially and axially inside this receptacle by the flange.

La pièce de retenue 13 comporte en outre avantageusement des lames élastiques 18, par exemple au nombre de trois (figure 2 et 4), qui viennent solliciter axialement une surface en vis-à-vis 19 de la lampe. Une fois l'ensemble en position finale, la lampe est donc centrée : d'une part radialement par sa zone de liaison cylindrique 20 qui vient se placer dans le logement homologue 21 du porte-lampe 3 ; et d'autre part axialement avec ses appuis 22 (figure 2) qui viennent contre les surfaces de portée 23 homologues (figures 2 et 5) du réflecteur 2, ce positionnement étant réalisé sous contrainte des lames élastiques 18.The retaining part 13 also advantageously comprises elastic blades 18, for example three in number (FIGS. 2 and 4), which come to stress axially a surface facing the lamp 19. Once the assembly in the final position, the lamp is therefore centered: on the one hand radially by its cylindrical connection zone 20 which is placed in the homologous housing 21 of the lamp holder 3; and on the other hand axially with its supports 22 (FIG. 2) which come against the homologous bearing surfaces 23 (FIGS. 2 and 5) of the reflector 2, this positioning being carried out under stress of the elastic blades 18.

Le verrouillage final du bras en position est réalisé au moyen d'un bossage 24 (figure 3 et 4) solidaire du porte-lampe et qui coopère avec une lame élastique homologue 25 (figure 4) qui peut être par exemple un prolongement de la pièce 13.Final locking of the arm in position is achieved by means of a boss 24 (FIGS. 3 and 4) integral with the lamp holder and which cooperates with a homologous elastic blade 25 (FIG. 4) which can for example be an extension of the part 13.

Pour réaliser ce verrouillage, après avoir descendu l'ensemble lampe et porte-lampe approximativement verticalement jusqu'à positionner la collerette 11 entre la pièce de retenue 13 et l'ouverture du projecteur 5 (des encoches 26 (figure 3) permettant réaliser un pré-centrage du porte-lampe), l'utilisateur fait pivoter le bras 12 d'un angle β (figure 4) par exemple de l'ordre de 20°, jusqu'à venir encliqueter le bossage 24 sous la partie arrondie de la lame élastique 25.To achieve this locking, after lowering the lamp and lamp holder assembly approximately vertically until the flange 11 is positioned between the retaining part 13 and the projector opening 5 (notches 26 (FIG. 3) allowing a pre -centering of the lamp holder), the user pivots the arm 12 by an angle β (FIG. 4) for example of the order of 20 °, until the boss 24 engages under the rounded part of the blade elastic 25.

Le démontage de la lampe se fait par la manoeuvre exactement inverse : pivotement du porte-lampe jusqu'à amener le bras en position sensiblement verticale, puis relevage de celui-ci en faisant traverser le réflecteur à la lampe par l'encoche 6.The lamp is disassembled by the exact opposite operation: pivoting of the lamp holder until the arm is brought to a substantially vertical position, then lifting of the latter by passing the reflector to the lamp through the notch 6.
