Description

PROJECTEUR DE VEHICULE AUTOMOBILE A OCCULTEUR ET BOITIER DE CONNEXION ELECTRIQUE MOTOR VEHICLE PROJECTOR WITH OCCULTOR AND ELECTRICAL CONNECTION BOX
L'invention concerne un projecteur de véhicule automobile pourvu d'un occulteur et d'un boîtier de connexion électrique amovible.The invention relates to a motor vehicle headlamp with a concealer and a removable electrical connection box.
Plus particulièrement, l'invention concerne le maintien d'un occulteur et d'un boîtier de connexion dans un projecteur.More particularly, the invention relates to the maintenance of a shield and a connection box in a projector.
Le document EP 1 286 109 décrit un projecteur de véhicule automobile, comprenant un boîtier de projecteur dans lequel sont montés une lampe, un réflecteur, un occulteur fixé sur le réflecteur, et un boîtier de connexion électrique pour alimenter la lampe. Un support pour le boîtier de connexion électrique est fixé au moyen de vis sur l'arrière du réflecteur. Le culot de la lampe est pourvu d'une bague engagée dans un orifice correspondant du réflecteur lorsque la lampe est en place. La lampe est maintenue dans cette position par la force d'un ressort placé sur le support. Le boîtier de connexion est fixé par des vis sur le support. Un tel montage présente l'inconvénient de nécessiter de nombreuses pièces montées par vissages ainsi que le maintien de la lampe par un ressort, ce qui complique le montage et oblige l'opérateur à utiliser les deux mains pour effectuer un changement de lampe ou de boîtier de connexion.EP 1 286 109 discloses a motor vehicle headlamp, comprising a headlamp housing in which are mounted a lamp, a reflector, a shield attached to the reflector, and an electrical connection box for powering the lamp. A bracket for the electrical connection box is fixed by means of screws on the back of the reflector. The base of the lamp is provided with a ring engaged in a corresponding orifice of the reflector when the lamp is in place. The lamp is held in this position by the force of a spring placed on the support. The connection box is fixed by screws on the support. Such an assembly has the disadvantage of requiring many pieces mounted by screwing and the retention of the lamp by a spring, which complicates the assembly and requires the operator to use both hands to make a change of lamp or housing connection.
L'invention vise à pallier ces inconvénients en proposant un projecteur dans lequel le boîtier de connexion peut être monté de façon simple de manière à permettre un montage plus rapide. A cet effet, l'objet de l'invention concerne un projecteur de véhicule automobile comprenant un boîtier de projecteur dans lequel sont montés une lampe, un réflecteur pourvu d'un orifice central pour le montage de la lampe, un occulteur présentant une partie occultrice entourant la lampe et solidaire d'un support, et un boîtier de connexion électrique amovible apte à être connecté à la lampe pour la raccorder à un circuit électrique, caractérisé en ce que le support de l'occulteur est pourvu de moyens de fixation destinés à être fixés sur la partie arrière du réflecteur et aptes à coopérer avec des moyens de blocage du boîtier de connexion afin de maintenir rigidement ce dernier en position connectée.The invention aims to overcome these disadvantages by providing a projector in which the connection box can be mounted in a simple manner to allow faster mounting. For this purpose, the subject of the invention relates to a motor vehicle headlamp comprising a headlamp housing in which are mounted a lamp, a reflector provided with a central hole for mounting the lamp, a concave having an occulting portion surrounding the lamp and secured to a support, and a removable electrical connection box adapted to be connected to the lamp for connection to an electrical circuit, characterized in that the carrier of the shield is provided with fixing means for to be fixed on the rear part of the reflector and able to cooperate with locking means of the connection box in order to rigidly hold the latter in the connected position.
Le maintien du boîtier en position connectée sur la lampe permet de maintenir celle-ci, sans nécessiter de moyens particuliers tels qu'un ressort. Avantageusement, les moyens de fixation de l'occulteur coopèrent avec les moyens de blocage du boîtier de connexion afin de maintenir rigidement ce dernier en position connectée suivant la direction de l'axe de l'orifice du réflecteur. Un tel maintien assure une bonne connexion du boîtier sur la lampe et un maintien efficace de la lampe.Maintaining the housing in position connected to the lamp can maintain it, without requiring special means such as a spring. Advantageously, the securing means of the occluder cooperate with the locking means of the connection box in order to rigidly hold the latter in the connected position in the direction of the axis of the orifice of the reflector. Such a hold ensures a good connection of the housing to the lamp and effective maintenance of the lamp.
Avantageusement, la lampe du projecteur comprend une collerette de maintien en appui contre le bord arrière de l'orifice central du réflecteur, et les moyens de fixation de l'occulteur sont aptes à coopérer avec la collerette afin de maintenir la lampe dans l'orifice du réflecteur lorsque le boîtier de connexion est déconnecté de la lampe. Ainsi, la lampe est maintenue en place même lorsque le boîtier n'est pas connecté.Advantageously, the projector lamp comprises a retaining flange bearing against the rear edge of the central orifice of the reflector, and the securing means of the concealer are adapted to cooperate with the flange to hold the lamp in the orifice reflector when the connection box is disconnected from the lamp. Thus, the lamp is held in place even when the housing is not connected.
Avantageusement, les moyens de fixation de l'occulteur et les moyens de blocage du boîtier coopèrent par encliquetage. Un montage et un démontage faciles et rapides du boîtier et de la lampe sont ainsi obtenus car il n'est plus nécessaire de visser et dévisser des vis.Advantageously, the securing means of the occluder and the locking means of the housing cooperate by snapping. Easy and fast assembly and disassembly of the housing and the lamp are thus obtained because it is no longer necessary to screw and unscrew screws.
Dans un mode de réalisation particulier, les moyens de fixation de l'occulteur comprennent au moins une patte de fixation conformée de manière à traverser l'orifice central du réflecteur sensiblement parallèlement à l'axe dudit orifice, la patte étant repliée sur elle-même de manière à former un pli s'étendant suivant une direction radiale de l'orifice et apte à être fixé sur l'arrière du réflecteur, l'extrémité de la patte faisant saillie radialement vers l'intérieur de l'orifice et étant apte à coopérer avec la collerette de la lampe ou les moyens de blocage du boîtier de connexion.In a particular embodiment, the securing means of the occluder comprise at least one fastening tab shaped so as to pass through the central orifice of the reflector substantially parallel to the axis of said orifice, the tab being folded back on itself so as to form a fold extending in a radial direction of the orifice and adapted to be fixed on the rear of the reflector, the end of the tab projecting radially inwardly of the orifice and being adapted to cooperate with the collar of the lamp or the locking means of the connection box.
La même patte sert ainsi au maintien de la lampe en l'absence du boîtier et au maintien du boîtier lorsqu'il est connecté à la lampe.The same tab thus serves to maintain the lamp in the absence of the housing and the maintenance of the housing when connected to the lamp.
Avantageusement, l'extrémité de la patte de fixation de l'occulteur est repliée sensiblement parallèlement à l'axe de l'orifice du réflecteur en direction de la partie occultrice de l'occulteur.Advantageously, the end of the fastening tab of the shield is folded substantially parallel to the axis of the reflector orifice in the direction of the occulting portion of the shield.
Avantageusement, la patte de fixation de l'occulteur est fixée par vissage ou rivetage sur le réflecteur. Lorsqu'une seule patte est prévue, seule une vis doit alors être vissée, ce qui permet de fixer rapidement l'occulteur. Avantageusement, les moyens de fixation sont formés d'une pièce avec l'occulteur.Advantageously, the bracket of the concealer is fixed by screwing or riveting on the reflector. When only one leg is provided, only one screw must then be screwed, which allows to quickly set the occulteur. Advantageously, the fastening means are formed in one piece with the concealer.
Avantageusement, les moyens de blocage du boîtier de connexion électrique comprennent au moins une patte de maintien s'étendant sensiblement parallèlement à l'axe de l'orifice du réflecteur et au moins un ressort disposé sur sa face destinée à être connectée à la lampe, et la patte de maintien et l'extrémité de la patte de fixation de l'occulteur sont conformées de manière à coopérer afin de bloquer le déplacement du boîtier suivant la direction axiale de l'orifice lorsque le boîtier est connecté à la lampe, le ressort étant comprimé entre le boîtier et la collerette de la lampe.Advantageously, the locking means of the electrical connection box comprise at least one retaining tab extending substantially parallel to the axis of the orifice of the reflector and at least one spring disposed on its face intended to be connected to the lamp, and the holding lug and the end of the bracket of the concealer are formed of so as to cooperate to block the displacement of the housing in the axial direction of the orifice when the housing is connected to the lamp, the spring being compressed between the housing and the flange of the lamp.
Avantageusement, la patte de maintien du boîtier est pourvue d'un poussoir latéral permettant de pousser la patte de maintien radialement en direction de l'axe de l'orifice du réflecteur afin de dégager la patte de maintien de la patte de fixation de l'occulteur. n est alors très facile de déconnecter le boîtier d'une seule main afin d'accéder à la lampe, par exemple pour la changer.Advantageously, the housing holding tab is provided with a lateral pusher for pushing the retaining tab radially towards the axis of the orifice of the reflector in order to disengage the retaining tab from the fastening tab of the cloaking. It is then very easy to disconnect the housing with one hand in order to access the lamp, for example to change it.
L'invention est maintenant décrite en référence aux dessins annexés, non limitatifs, dans lesquels : la figure 1 est une vue en coupe des éléments d'un projecteur selon l'invention, le boîtier étant connecté sur la lampe ; la figure 2 est une vue en coupe similaire à la figure 1, le boîtier n'étant pas encore connecté sur la lampe.The invention is now described with reference to the accompanying non-limiting drawings, in which: FIG. 1 is a sectional view of the elements of a headlight according to the invention, the housing being connected to the lamp; Figure 2 is a sectional view similar to Figure 1, the housing is not yet connected to the lamp.
La figure 1 représente en coupe un réflecteur 1, un occulteur 2, une lampe 3 et un boîtier de connexion électrique 4 destiné à raccorder la lampe à un circuit électrique non représenté. Ces éléments sont situés à l'intérieur du boîtier d'un projecteur de véhicule automobile non représenté.Figure 1 shows in section a reflector 1, a shield 2, a lamp 3 and an electrical connection box 4 for connecting the lamp to an electrical circuit not shown. These elements are located inside the housing of a motor vehicle headlamp not shown.
De manière conventionnelle, le réflecteur 1 est fixé à l'intérieur du boîtier de projecteur de manière réglable. Le réflecteur présente une forme parabolique pourvue d'un orifice central 5 destiné à recevoir la lampe 3. La lampe 3 présente une partie de support 6 pourvue d'une collerette 7 destinée à venir en appui contre la face arrière du réflecteur 1, sur le bord de l'orifice central 5, tel que visible sur les figures.Conventionally, the reflector 1 is fixed inside the projector housing in an adjustable manner. The reflector has a parabolic shape provided with a central orifice 5 intended to receive the lamp 3. The lamp 3 has a support portion 6 provided with a flange 7 intended to bear against the rear face of the reflector 1, on the edge of the central orifice 5, as visible in the figures.
Dans la présente demande, la face arrière des différents éléments est celle dirigée vers le boîtier de connexion 4 (c'est-à-dire vers la droite des figures), la face avant étant située du côté de la lampe (vers la gauche des figures).In the present application, the rear face of the various elements is that directed towards the connection box 4 (that is to the right of the figures), the front face being located on the side of the lamp (to the left of the figures).
La lampe présente sur la face arrière de son support 6 des fiches 8 de connexion électrique au boîtier de connexion 4. L'occulteur 2 présente une partie occultrice 2a entourant la lampe solidaire d'un support 2b. La partie occultrice 2a, sensiblement conique, est placée autour de la lampe 3.The lamp has, on the rear face of its support 6, plugs 8 for electrical connection to the connection box 4. The concealer 2 has an occulting portion 2a surrounding the lamp integral with a support 2b. The concave part 2a, substantially conical, is placed around the lamp 3.
Le boîtier de connexion 4 présente sur sa face avant 4a destinée à être raccordée à la lampe, des orifices (non représentés) destinés à recevoir les fiches 8 de la lampe. Il peut ainsi être facilement branché et débranché de la lampe.The connection box 4 has on its front face 4a intended to be connected to the lamp, orifices (not shown) for receiving the plugs 8 of the lamp. It can thus be easily connected and disconnected from the lamp.
Selon l'invention, le support 2b de l'occulteur est pourvu de moyens de fixation destinés à être fixés sur la partie arrière du réflecteur et aptes à coopérer avec des moyens de blocage du boîtier de connexion afin de maintenir rigidement ce dernier en position connectée. De préférence, cette coopération permet de maintenir rigidement ce dernier en position connectée suivant la direction de l'axe X de l'orifice 5 du réflecteur 1. Dans l'exemple représenté, les moyens de fixation de l'occulteur comprennent une patte de fixation 9, conformée de manière à traverser l'orifice central 5 du réflecteur sensiblement parallèlement à l'axe X dudit orifice. La patte 9 est solidaire de la partie occultrice 2a, et son extrémité distale de la partie 2a est repliée sur elle-même de manière à former un pli 9b (figure 2) s'étendant suivant une direction radiale de l'orifice 5 et apte à être fixé sur l'arrière du réflecteur 1. A cet effet, un orifice est prévu traversant le pli afin de fixer la patte au moyen d'une vis 10, ou d'un rivet, sur l'arrière du réflecteur. Afin de permettre le passage de la patte 9 sans gêner le montage de la lampe, l'orifice 5 du réflecteur présente une fente dans laquelle est logée la patte. De cette manière, le diamètre de l'orifice 5 n'est pas réduit.According to the invention, the support 2b of the shield is provided with fixing means intended to be fixed on the rear part of the reflector and able to cooperate with locking means of the connection box in order to rigidly hold the latter in the connected position. . Preferably, this cooperation makes it possible to rigidly hold the latter in a position connected in the direction of the axis X of the orifice 5 of the reflector 1. In the example shown, the securing means of the concealer comprise a fixing lug 9, shaped so as to pass through the central orifice 5 of the reflector substantially parallel to the axis X of said orifice. The tab 9 is integral with the occulting portion 2a, and its distal end of the portion 2a is folded back on itself so as to form a fold 9b (Figure 2) extending in a radial direction of the orifice 5 and fit to be fixed on the back of the reflector 1. For this purpose, an orifice is provided through the fold to secure the tab by means of a screw 10, or a rivet, on the back of the reflector. In order to allow the passage of the tab 9 without impeding the mounting of the lamp, the orifice 5 of the reflector has a slot in which is housed the tab. In this way, the diameter of the orifice 5 is not reduced.
L'extrémité libre 9a de la patte fait saillie radialement vers l'intérieur de l'orifice 5 (en direction de l'axe X) et est apte à coopérer avec la collerette 7 de la lampe ou les moyens de blocage du boîtier de connexion. A cet effet, elle est, de préférence, repliée sensiblement parallèlement à l'axe X de l'orifice du réflecteur en direction de la partie occultrice 2a de l'occulteur.The free end 9a of the tab projects radially towards the inside of the orifice 5 (in the direction of the axis X) and is able to cooperate with the flange 7 of the lamp or the locking means of the connection box . For this purpose, it is preferably folded substantially parallel to the axis X of the reflector orifice in the direction of the occulting portion 2a of the occulter.
Afin de simplifier la réalisation de l'occulteur, la patte 9 est de préférence réalisée d'une pièce avec le support 2b et la partie occultrice 2a de l'occulteur, tel que représenté sur les figures.In order to simplify the production of the occluder, the tab 9 is preferably made in one piece with the support 2b and the occulting portion 2a of the occluder, as shown in the figures.
Le boîtier de connexion 4 est pourvu de moyens de blocage comprenant une patte de maintien 11 s'étendant sensiblement parallèlement à l'axe X de l'orifice du réflecteur et au moins un ressort 12 (représenté uniquement figure 2) disposé sur sa face avant 4a destinée à être connectée à la lampe.The connection box 4 is provided with locking means comprising a holding tab 11 extending substantially parallel to the axis X of the orifice of the reflector and at least one spring 12 (shown only in FIG. 2) disposed on its front face 4a intended to be connected to the lamp.
La patte de maintien 11 et l'extrémité 9a de la patte de fixation l'occulteur sont conformées de manière à coopérer afin de bloquer le déplacement du boîtier suivant la direction axiale de l'orifice lorsque le boîtier 4 est connecté à la lampe. A cet effet, la patte de maintien s'étend sensiblement parallèlement à l'axe X de l'orifice central 5 du réflecteur et fait saillie de la face avant 4a du boîtier de connexion vers l'avant. L'extrémité de cette patte est repliée radialement vers l'extérieur, afin de venir en prise avec l'extrémité 9a de la patte de fixation de l'occulteur.The holding lug 11 and the end 9a of the securing lug the concave are shaped so as to cooperate to block the movement of the housing in the axial direction of the orifice when the housing 4 is connected to the lamp. For this purpose, the holding lug extends substantially parallel to the axis X of the central orifice 5 of the reflector and projects from the front face 4a of the connection box towards the front. The end of this tab is folded radially outwardly, in order to engage with the end 9a of the bracket of the concealer.
Le ressort 12 est alors comprimé entre le boîtier 4 et la collerette 7 de la lampe. De préférence, deux ressorts 12 sont prévus de part et d'autre du boîtier 4. Dans l'exemple, la patte de maintien 11 du boîtier est pourvue d'un poussoir latéral 13 s'étendant sensiblement parallèlement à la patte 11. Ce poussoir 13 permet de pousser la patte de maintien 11 radialement en direction de l'axe X de l'orifice du réflecteur afin de la dégager de l'extrémité 9a de la patte de fixation de l'occulteur. Le boîtier peut ainsi aisément être déconnecté d'une seule main.The spring 12 is then compressed between the housing 4 and the flange 7 of the lamp. Preferably, two springs 12 are provided on either side of the casing 4. In the example, the retaining tab 11 of the casing is provided with a lateral pusher 13 extending substantially parallel to the tab 11. This pusher 13 makes it possible to push the retaining lug 11 radially in the direction of the X axis of the orifice of the reflector in order to disengage it from the end 9a of the fastening lug of the concealer. The housing can easily be disconnected with one hand.
Lorsque le boîtier de connexion n'est pas encore raccordé à la lampe 3, tel que représenté sur la figure 2, l'extrémité 9a de la patte de fixation vient en prise avec la collerette 7 de la lampe 3, de sorte que celle-ci est maintenue en place malgré l'absence du boîtier 4. Il n'est ainsi pas nécessaire de prévoir un ressort spécifique pour maintenir la lampe.When the connection box is not yet connected to the lamp 3, as shown in FIG. 2, the end 9a of the fixing tab engages with the collar 7 of the lamp 3, so that it is held in place despite the absence of the housing 4. It is thus not necessary to provide a specific spring to maintain the lamp.
Bien entendu, d'autres modes de réalisation des moyens de fixation et de blocage peuvent être envisagés. Par exemple, on peut prévoir deux pattes de maintien 11 du boîtier 4 coopérant chacune avec une patte de fixation 9 de l'occulteur. En disposant ces pattes symétriquement, la mise en place du boîtier 4 reste simple et rapide et réalisable d'une seule main. Of course, other embodiments of the fixing and locking means may be envisaged. For example, one can provide two retaining lugs 11 of the housing 4 each cooperating with a fastening lug 9 of the occulter. By arranging these tabs symmetrically, the establishment of the housing 4 remains simple and fast and achievable with one hand.
