Description

La présente invention a pour objet un dispositif projecteur comportant un bloc actionneur multifonctions. Par actionneur, on désigne un élément électrotechnique, de type moteur, associé a une chaîne cinématique permettant le mouvement d'un élément cible. Le plus souvent, un actionneur comporte une carte de contrôle électronique destinée à gérer son fonctionnement. Le bloc actionneur présent dans le dispositif projecteur selon l'invention est multifonctions : il permet de réaliser une première fonction consistant dans le basculement d'un volet pivotant au sein du dispositif projecteur, et une deuxième fonction, dite fonction DBL. Un but essentiel de l'invention est de pouvoir réaliser ces deux fonctions, au sein d'un même dispositif projecteur, en occupant un volume aussi limité que possible et sans que les différents éléments intervenant dans la cinématique de ces deux fonctions se gênent mutuellement.The present invention relates to a projector device comprising a multifunctional actuator block. By actuator is meant an electrotechnical element, engine type, associated with a kinematic chain allowing the movement of a target element. Most often, an actuator comprises an electronic control card for managing its operation. The actuator block present in the projector device according to the invention is multifunctional: it allows a first function consisting in the tilting of a pivoting flap within the projector device, and a second function, called DBL function. An essential object of the invention is to be able to perform these two functions, within a same projector device, occupying as limited a volume as possible and without the various elements involved in the kinematics of these two functions interfering with each other.

Le domaine de l'invention est, d'une façon générale, celui des projecteurs de véhicule automobile. Dans ce domaine, on connaît différents types de dispositifs projecteurs, parmi lesquels on trouve essentiellement :

  • des feux de position, d'intensité et de portée faible ;
  • des feux de croisement, ou codes, d'intensité plus forte et de portée sur la route avoisinant 70 mètres, qui sont utilisés essentiellement la nuit et dont la répartition du faisceau lumineux est telle qu'elle permet de ne pas éblouir le conducteur d'un véhicule croisé ;
  • des feux de route longue portée, et des feux de complément de type longue portée, dont la zone de vision sur la route avoisine 200 mètres, et qui doivent être éteints lorsque l'on croise un autre véhicule afin de ne pas éblouir son conducteur ;
  • des feux anti-brouillard.
The field of the invention is, in general, that of motor vehicle headlights. In this field, various types of projectors devices are known, among which we find essentially:
  • position, intensity and low range lights;
  • low beam, or codes, of greater intensity and range on the road of about 70 meters, which are used mainly at night and whose distribution of the light beam is such that it does not dazzle the driver of a crossover vehicle;
  • long-range headlamps, and long-range supplement lights, whose vision zone on the road is approximately 200 meters, and which must be extinguished when crossing another vehicle so as not to dazzle its driver;
  • fog lights.

Par ailleurs, on connaît un type de projecteur perfectionné, appelé projecteur bifonction, qui cumule les fonctions de feux de croisement et de feux longue portée : à cet effet, on peut par exemple disposer à l'intérieur du projecteur bifonction un cache amovible pouvant passer sur commande d'une première position dans laquelle il occulte une partie du signal lumineux produit par la source lumineuse du projecteur, la portée du projecteur étant ainsi limitée à celle des feux de croisement pour ne pas éblouir les autres conducteurs, à une deuxième position dans laquelle il n'occulte pas le signal lumineux produit par la source lumineuse du projecteur, la portée du projecteur correspondant alors à celle des feux de route, comme décrit dans le brevet EP 1 197 387 . Cet exemple de réalisation est principalement mis en oeuvre dans les dispositifs projecteurs de type elliptiques. Sur le même principe, il existe aussi des projecteurs multi-fonction, où un cache amovible peut adopter plus de deux positions pour occulter de plusieurs façons de façon sélective le faisceau lumineux émis par la source : on peut ainsi avoir des caches bi fonction code trafic à droite/code trafic à gauche, des caches tri-fonction code trafic à droite/code trafic à gauche/route etc ....Furthermore, we know a type of advanced projector, called dual-function projector, which combines the functions of low beam and long range lights: for this purpose, for example, there may be inside the bifunctional projector a removable cover that can pass on command of a first position in which it obscures part of the light signal produced by the light source of the projector, the range of the projector being thus limited to that of the dipped beam to not dazzle other drivers, to a second position in which it does not obscure the light signal produced by the light source of the projector, the range of the projector then corresponding to that of high beam as described in EP 1 197 387. This exemplary embodiment is mainly implemented in elliptical projectors devices. On the same principle, there are also multi-function projectors, where a removable cover can adopt more than two positions to obscure in a few ways selectively the light beam emitted by the source: it can thus have caches bi function traffic code right / traffic code left, caches tri-function traffic code right / traffic code left / route etc ....

On connaît également un type particulier de projecteur, qui permet, notamment la nuit, d'obtenir une image visible de la route sur un écran de contrôle. Ce type de projecteur est en fait un projecteur de type feu de route, équipé d'un filtre infra-rouge basculant, qui peut passer sur commande d'une première position dans laquelle il filtre l'ensemble des signaux lumineux produits par la source lumineuse du projecteur, de telle sorte que seuls les rayons infra-rouges, non éblouissants, sortent effectivement du dispositif projecteur, à une deuxième position dans laquelle le filtre n'occulte aucun signal lumineux produit par la source lumineuse du projecteur, la portée du projecteur correspondant alors à celle des feux de route. On pourra se rapporter, par exemple, au brevet E P 1 139 011.There is also a particular type of projector, which allows, especially at night, to obtain a visible image of the road on a control screen. This type of projector is in fact a headlamp-type headlamp, equipped with a tilting infra-red filter, which can be placed on command from a first position in which it filters all the light signals produced by the light source. the projector, so that only infra-red, glare-free rays actually emerge from the projector device, to a second position in which the filter does not obscure any light signal produced by the light source of the projector, the range of the corresponding projector then to that of the driving lights. For example, reference can be made to the patent E P 1 139 011.

Dans le cadre de l'invention, le cache amovible et le filtre infra-rouge sont deux exemples particuliers de volet pivotant intervenant dans la première fonction du dispositif projecteur selon l'invention.In the context of the invention, the removable cover and the infra-red filter are two particular examples of pivoting shutter involved in the first function of the projector device according to the invention.

Par ailleurs, on connaît également, en complément des fonctions projecteurs principales classique, qui viennent d'être mentionnées, notamment codes et routes, différents perfectionnements qui sont progressivement apparus. On a ainsi vu se développer des fonctions élaborées, ou fonctions avancées, parmi lesquelles on trouve notamment une fonction dite DBL (Dynamic Bending Light en anglais pour lumière virage mobile). La fonction DBL permet de modifier l'orientation d'un faisceau lumineux produit par une source lumineuse, de telle sorte que lorsque le véhicule aborde un virage, la route soit éclairée de façon optimale.Furthermore, it is also known, in addition to the main conventional headlight functions, which have just been mentioned, including codes and routes, various improvements that have gradually appeared. We have developed sophisticated functions, or advanced functions, among which we find in particular a function called DBL (Dynamic Bending Light in English for light bend mobile). The DBL function makes it possible to modify the orientation of a light beam produced by a light source, so that when the vehicle approaches a turn, the road is illuminated optimally.

D'une façon générale, les dispositifs projecteurs concernés par l'invention sont tous ceux qui sont :

  • susceptibles d'être équipés d'un volet mobile, notamment par pivotement, indépendamment de la fonction remplie par ledit volet mobile, capable de basculer, d'évoluer, sur commande et grâce à la présence d'un moteur, entre une première position, dite position active, dans laquelle des signaux lumineux, émis par une source lumineuse du dispositif projecteur équipé dudit volet, rencontrent le volet pivotant, et une deuxième position, dite position passive, dans laquelle les signaux lumineux ne rencontrent pas le volet pivotant ;
  • aptes à mettre en oeuvre la fonction DBL.
In general, the projectors concerned by the invention are all those who are:
  • capable of being equipped with a movable flap, in particular by pivoting, independently of the function performed by said movable flap, able to switch, to evolve, on command and thanks to the presence of a motor, between a first position, said active position, wherein light signals, emitted by a light source of the projector device equipped with said flap, meet the pivoting flap, and a second position, said passive position, in which the light signals do not meet the pivoting flap;
  • able to implement the DBL function.

On ne connaît pas, dans l'état de la technique, de dispositifs projecteurs qui associent ces deux fonctions. En outre, la réalisation d'un dispositif projecteur qui juxtaposerait, tels qu'ils existent dans l'état de la technique, un actionneur permettant la réalisation de la première fonction, et un actionneur permettant la réalisation de la deuxième fonction, n'aboutirait pas à une solution satisfaisante : en effet, le premier actionneur comporte un premier moteur qui, dans l'état de la technique, est disposé dans un premier boîtier sur une partie avant du dispositif projecteur, et qui gênerait le mouvement engendré par l'actionneur associé à la deuxième fonction, ce deuxième actionneur étant disposé dans un deuxième boîtier sur une partie arrière du dispositif projecteur. La présence de ces deux boîtiers distincts serait par ailleurs pénalisante en terme d'encombrement. Un tel dispositif d'éclairage selon le préambule de la revendication 1 est connu du document FR-A-2808750.It is not known, in the state of the art, projector devices that combine these two functions. In addition, the creation of a projector device which juxtaposed, as they exist in the state of the art, an actuator for performing the first function, and an actuator for performing the second function, would result not to a satisfactory solution: in fact, the first actuator comprises a first motor which, in the state of the art, is disposed in a first housing on a front part of the projector device, and which would hinder the movement generated by the actuator associated with the second function, the second actuator being disposed in a second housing on a rear portion of the projector device. The presence of these two separate boxes is also penalizing in terms of space. Such a lighting device according to the preamble of claim 1 is known from FR-A-2808750.

C'est un objet de l'invention de répondre à l'ensemble des inconvénients qui viennent d'être mentionnés. A cet effet, dans l'invention, on propose un dispositif projecteur qui présente un unique bloc actionneur multifonctions dans lequel on regroupe différents éléments, notamment un premier moteur et/ou un deuxième moteur, permettant la mise en oeuvre d'une fonction de basculement d'un volet pivotant et d'une fonction DBL. Le bloc actionneur multifonctions est intégré dans un boîtier qui est mobile selon un axe de rotation permettant le mouvement correspondant à la fonction DBL du dispositif projecteur. L'ensemble des éléments intervenant dans les actionneurs associés à ces deux fonctions sont rattachés au boîtier mobile, de telle sorte que les éléments des deux actionneurs suivent le mouvement de rotation généré par la fonction DBL, assurant ainsi la possibilité de mettre en oeuvre la première fonction quelle que soit l'orientation du dispositif projecteur imposé par la deuxième fonction.It is an object of the invention to respond to all the disadvantages just mentioned. For this purpose, in the invention, there is provided a projector device which has a single multifunctional actuator block in which different elements are grouped together, in particular a first motor and / or a second motor, allowing the implementation of a failover function. a swivel flap and a DBL function. The multifunctional actuator block is integrated in a housing that is movable along an axis of rotation allowing the movement corresponding to the DBL function of the projector device. All the elements involved in the actuators associated with these two functions are attached to the mobile housing, so that the elements of the two actuators follow the rotational movement generated by the DBL function, thus ensuring the possibility of implementing the first one. function whatever the orientation of the projector device imposed by the second function.

L'invention concerne donc essentiellement un dispositif projecteur comportant notamment :

  • une source lumineuse disposée dans un réflecteur qui produit un faisceau lumineux émis, au niveau d'une face de sortie du réflecteur, notamment selon un axe optique sensiblement horizontal du dispositif projecteur;
  • un volet mobile notamment pivotant pouvant évoluer, au moyen d'un premier moteur, au moins entre au moins deux positions, par exemple entre une position passive dans laquelle il n'intercepte pas le faisceau lumineux et une position active dans laquelle il intercepte au moins une partie du faisceau lumineux;
tel que le dispositif projecteur comporte un boîtier mobile au moyen d'un second moteur, notamment mobile en rotation, par rapport à un cadre fixe du dispositif projecteur, selon un axe sensiblement vertical et /ou sensiblement perpendiculaire à l'axe optique, ledit boîtier comportant au moins un compartiment pour recevoir et maintenir d'une part le premier moteur et d'autre part un deuxième moteur assurant le mouvement du boîtier.The invention therefore essentially relates to a projector device comprising in particular:
  • a light source disposed in a reflector which produces a light beam emitted at an exit face of the reflector, in particular along a substantially horizontal optical axis of the projector device;
  • a mobile flap, in particular a pivoting flap, which can move, by means of a first motor, at least between at least two positions, for example between a passive position in which it does not intercept the light beam and an active position in which it intercepts at least a part of the light beam;

Les éléments apparaissant sur différentes figures conservent les mêmes référence.The elements appearing in different figures retain the same reference.

Les figures 1 et 2 mettent en évidence les différents éléments principaux destinés à être intégrés dans un dispositif projecteur selon l'invention. On trouve ainsi, notamment, les différents éléments suivants :

  • un réflecteur 101, au coeur duquel on vient placer une source lumineuse 102, visible uniquement à la figure 4, maintenue par un élément porte-lampe 103, pour produire un faisceau lumineux correspondant à l'utilisation faite du dispositif projecteur. On définit pour le réflecteur 101 une face de sortie, qui est un plan perpendiculaire à l'axe optique du dispositif projecteur, et qui est matérialisée par un pourtour 104. Le faisceau lumineux produit est dirigé selon un axe optique sensiblement horizontal et dirigé vers l'avant du véhicule afin d'éclairer de façon optimale une route empruntée. Par les termes axe optique sensiblement horizontal, on désigne le fait que l'axe optique, qui correspond à une direction d'intensité maximale en émission de lumière par le dispositif projecteur considéré, est contenu dans un plan parallèle à la route, à un ou deux degrés près.
  • une plaque photométrique 105, destinée à être disposée en appui sur le pourtour 104. Le rôle de la plaque photométrique 105 est d'obstruer différentes cavités qui laisseraient échapper des fuites photométriques hors du dispositif projecteur, lesdites fuites photométriques n'étant pas destinées à contribuer à l'élaboration du faisceau lumineux attendu. La forme de la plaque photométrique est telle qu'elle n'intercepte pas les rayons lumineux nécessaires à l'élaboration du faisceau lumineux attendu, qu'il s'agisse d'un faisceau lumineux de type route ou de type code. En outre, elle joue un rôle de protection thermique, notamment des composants électroniques et des moteurs vis-à-vis de la chaleur émise par le faisceau lumineux.
  • un volet pivotant 106 destiné à remplir la première fonction précédemment décrite. Dans l'exemple illustré, le volet pivotant est du type cache amovible, c'est à dire qu'il présente une forme permettant d'obtenir, par projection, soit un faisceau code réglementaire lorsqu'il est dans une position active dans laquelle il intercepte une partie du faisceau lumineux produit par la source lumineuse 102, soit un faisceau route réglementaire lorsqu'il est dans une position passive dans laquelle il n'intercepte pas le faisceau lumineux produit par la source lumineuse 102 ; la forme du volet pivotant permettant d'obtenir une ligne de coupure réglementaire pour les codes est réalisée dans une tige présentant, à une de ses extrémités, une roue dentée 107 et de deux embouts circulaires 108 situés à chaque terminaison de la tige. Un ressort de rappel 109 est disposé sur une des terminaisons de la tige : il permet de provoquer instantanément la basculement du volet pivotant dans une direction opposée à celle donnée par un moteur. Dans d'autres exemples de réalisation du dispositif projecteur selon l'invention, le volet pivotant peut être du type filtre infra-rouge ou multi-fonction.
  • un premier moteur 110 destiné à actionner le volet pivotant. De préférence, pour des raisons d'encombrement (ou d'autres raisons notamment de pilotage électronique), on utilise un moteur à courant continu. Le premier moteur est essentiellement constitué d'un bloc moteur qui entraîne en rotation une tige moteur supportant un premier pignon 111.
  • un deuxième moteur 112 destiné à provoquer le mouvement du dispositif projecteur pour remplir la fonction DBL. Pour des raisons de précision des mouvements provoqués par ce moteur, on utilise de préférence un moteur de type moteur pas à pas. Le deuxième moteur 112 est essentiellement constitué d'un bloc moteur qui entraîne en rotation une tige moteur supportant, dans l'exemple illustré, une vis sans fin 113. La vis sans fin permet d'entraîner en rotation un deuxième pignon 114 dont le rôle sera précisé ultérieurement.
  • une carte de contrôle électronique 115 destinée à gérer le fonctionnement d'au moins un des deux moteurs 110 et 112. Dans un mode de réalisation préféré du dispositif projecteur selon l'invention, la carte électronique 115 gère le fonctionnement du premier moteur 110 et du deuxième moteur 112. On réalise ainsi un gain de place non négligeable dans la réalisation du dispositif projecteur. La carte électronique 115 peut être équipée d'un capteur de type capteur à effet hall 116 qui lui permet de connaître précisément, à chaque instant, un angle de rotation, par rapport à un angle de référence, du dispositif projecteur lié à la mise en oeuvre de la fonction DBL.
  • une pièce de conduction métallique 117 supportant un ensemble de languettes de connexion 118 qui sont destinées à entrer en contact avec différentes pistes de la carte électronique 115, essentiellement afin d'assurer l'alimentation de la carte et l'alimentation électrique du premier moteur 110 et du deuxième moteur 112. Dans un procédé de fabrication particulier du dispositif projecteur selon l'invention, on dispose, avant de verser la matière plastique liquéfiée, la pièce métallique 117 supportant les différentes languettes de connexion 118 dans un moule destiné à fabriquer le boîtier mobile 119, puis on sectionne, une fois la pièce monobloc démoulée, les différentes languettes de connexion de telle sorte qu'elles ne soient plus conductrices entre elles. Un tel procédé de fabrication permet de s'affranchir d'une disposition successive, délicate à réaliser, des languettes de connexion.
  • un boîtier mobile en rotation 119, par rapport à un cadre fixe 120 visible aux figure 3 et 4, du dispositif projecteur, selon un axe sensiblement vertical et perpendiculaire à l'axe optique. Par cadre fixe du dispositif projecteur, on désigne une pièce qui n'est pas susceptible d'entrer en mouvement au sein du dispositif projecteur. Par axe sensiblement vertical, on désigne un axe perpendiculaire à un pan défini par une route sur laquelle circule le véhicule automobile comportant le dispositif projecteur selon l'invention, à un ou deux degrés près. Le boîtier mobile 119 est essentiellement constitué d'un cadre présentant une ouverture centrale 137 pour être traversé par le réflecteur 101 lors de l'assemblage des différents éléments constituant le dispositif projecteur.
    Le boîtier mobile 119 présente par ailleurs, ménagés dans son épaisseur, un ensemble de compartiments pour recevoir et/ou maintenir les différents éléments qui viennent d'être mentionnés. On trouve ainsi, dans l'exemple représenté, un premier compartiment 121 pour recevoir et maintenir le premier moteur 110 ; un deuxième compartiment 122 pour recevoir et maintenir le deuxième moteur 112 ; un troisième compartiment 123 pour recevoir et maintenir la carte électronique 115. Dans l'exemple de réalisation représenté, le troisième compartiment 123 est ménagé dans une partie latérale du cadre constituant le boîtier mobile en rotation 119. Une telle disposition, sur le côté du dispositif projecteur, permet d'éloigner au maximum la carte électronique 115 des zones de chaleur les plus élevées du dispositif projecteur. La position relative des premier moteur 110, deuxième moteur 112 et de la carte de contrôle électronique 115 impose que la pièce de conduction métallique 117 ait une forme en équerre, comme montré sur les figures 1 et 2, afin d'assurer la connexion entre ces différents éléments.
    Le boîtier mobile 119 comporte par ailleurs deux protubérances circulaires 124, situées au niveau d'une partie centrale d'une face supérieure et d'une face inférieure de son cadre, qui sont destinées à être enclenchées dans des cavités prévues à cet effet du cadre fixe 120 du dispositif projecteur selon l'invention, pour permettre le mouvement en rotation de la fonction DBL.
    Le boîtier mobile 119 comporte enfin au moins un premier élément de maintien 125 et un deuxième élément de maintien 126, visible à la figure 4, permettant de recevoir les extrémités 108 de la tige formant support du volet pivotant 106; une fois que le volet pivotant 106 est maintenu par les éléments de maintien 125 et 126, elle peut évoluer en rotation autour d'un axe de rotation, dit axe de rotation du volet pivotant, défini par une droite passant par le centre des deux éléments de maintien, ladite droite étant grossièrement matérialisée par la tige. Un dégagement 127 est prévu dans la structure du boîtier mobile 119 pour laisser évoluer en rotation la roue dentée 107.
  • un capot 128, destiné notamment à fermer les différents compartiments qui viennent d'être mentionnés, afin de garantir l'étanchéité de ces compartiments.
Figures 1 and 2 highlight the various main elements to be integrated in a projector device according to the invention. We thus find, in particular, the following elements:
  • a reflector 101, at the heart of which one comes to place a source 102, visible only in Figure 4, held by a lamp holder element 103, to produce a light beam corresponding to the use made of the projector device. For the reflector 101, an output face is defined, which is a plane perpendicular to the optical axis of the projector device, and which is embodied by a periphery 104. The light beam produced is directed along a substantially horizontal optical axis and directed towards the 'front of the vehicle to illuminate optimally a borrowed road. By the term substantially horizontal optical axis, it is meant that the optical axis, which corresponds to a direction of maximum intensity in light emission by the projector device considered, is contained in a plane parallel to the road, at one or two degrees close.
  • a photometric plate 105, intended to be placed in abutment on the perimeter 104. The role of the photometric plate 105 is to obstruct different cavities which would let photometric leakage escape from the projector device, said photometric leaks not being intended to contribute to the development of the expected light beam. The shape of the photometric plate is such that it does not intercept the light rays necessary for the development of the expected light beam, whether it is a light beam of the road type or code type. In addition, it plays a role of thermal protection, including electronic components and motors vis-à-vis the heat emitted by the light beam.
  • a pivoting flap 106 for filling the first function described above. In the illustrated example, the pivoting flap is of the removable cache type, that is to say that it has a shape that makes it possible, by projection, to obtain a regulatory code beam when it is in an active position in which it intercepts a portion of the light beam produced by the light source 102, a regulatory road beam when in a passive position in which it does not intercept the light beam produced by the light source 102; the shape of the pivoting flap for obtaining a regulatory cutoff line for the codes is made in a rod having at one of its ends, a gear wheel 107 and two circular tips 108 located at each end of the rod. A return spring 109 is disposed on one of the endings of the rod: it makes it possible to instantly cause the tilting of the pivoting flap in a direction opposite to that given by an engine. In other embodiments of the projector device according to the invention, the pivoting flap may be of the infra-red filter or multi-function type.
  • a first motor 110 for actuating the pivoting flap. Preferably, for reasons of space (or other reasons including electronic control), a DC motor is used. The first motor essentially consists of a motor unit which rotates a motor rod supporting a first pinion 111.
  • a second motor 112 for causing the movement of the projector device to perform the DBL function. For reasons of precision of the movements caused by this motor, a motor of the stepper motor type is preferably used. The second motor 112 essentially consists of a motor unit which drives in rotation a motor shaft supporting, in the example illustrated, a worm 113. The worm is used to drive in rotation a second pinion 114 whose role will be specified later.
  • an electronic control card 115 intended to manage the operation of at least one of the two motors 110 and 112. In a preferred embodiment of the projector device according to the invention, the electronic card 115 manages the operation of the first motor 110 and the second motor 112. This provides a significant space saving in the embodiment of the projector device. The electronic card 115 may be equipped with a sensor of the hall effect sensor type 116 which enables it to know precisely, at each instant, an angle of rotation, with respect to a reference angle, of the projector device related to the implementation. of the DBL function.
  • a metal conduction piece 117 supporting a set of connection tongues 118 which are intended to come into contact with different tracks of the electronic card 115, essentially to ensure the power supply of the card and the power supply of the first motor 110 and in the second engine 112. In a particular manufacturing process of the projector device according to the invention, it is possible, before pouring the liquefied plastic material, the metal part 117 supporting the various connection tongues 118 in a mold intended to manufacture the housing mobile 119, then we cut, once the monoblock part unmolded, the different connecting tabs so that they are no longer conductive between them. Such a manufacturing method makes it possible to dispense with a successive arrangement, which is difficult to make, of connection tongues.
  • a rotating housing 119, with respect to a fixed frame 120 visible in FIGS. 3 and 4, of the projector device, along a substantially vertical axis and perpendicular to the optical axis. Fixed frame of the projector device means a room that is not likely to move in the projector device. By substantially vertical axis is an axis perpendicular to a section defined by a road on which the motor vehicle comprising the projector device according to the invention, to one or two degrees. The mobile housing 119 consists essentially of a frame having a central opening 137 to be traversed by the reflector 101 during assembly of the various elements constituting the projector device.
    The mobile housing 119 has, moreover, formed in its thickness, a set of compartments to receive and / or maintain the various elements that have just been mentioned. There is thus, in the example shown, a first compartment 121 for receiving and maintaining the first motor 110; a second compartment 122 for receiving and holding the second motor 112; a third compartment 123 for receiving and holding the electronic card 115. In the embodiment shown, the third compartment 123 is formed in a side portion of the frame constituting the rotating housing 119. Such an arrangement on the side of the device projector, makes it possible to move the electronic card 115 as far as possible away from the highest heat zones of the projector device. The relative position of the first motor 110, second motor 112 and the electronic control card 115 requires the metal conduction piece 117 to have an angled shape, as shown in FIGS. 1 and 2, in order to ensure the connection between these elements. different elements.
    The mobile housing 119 also has two circular protuberances 124, located at a central portion of an upper face and a lower face of its frame, which are intended to be engaged in cavities provided for this purpose of the frame fixed 120 of the projector device according to the invention, to allow the rotational movement of the DBL function.
    The mobile housing 119 finally has at least one first holding member 125 and a second holding member 126, visible in Figure 4, for receiving the ends 108 of the support rod of the pivoting flap 106; once the pivoting flap 106 is held by the holding elements 125 and 126, it can move in rotation about an axis of rotation, called the axis of rotation of the pivoting flap, defined by a line passing through the center of the two elements. maintaining said right being roughly materialized by the rod. A clearance 127 is provided in the structure of the mobile housing 119 to allow the gear wheel 107 to rotate.
  • a cover 128, intended in particular to close the different compartments that have just been mentioned, to ensure the sealing of these compartments.

Les figures 3 et 4 mettent en évidence, en montrant différentes vues du dispositif projecteur selon l'invention assemblé, les interactions entre les différents éléments intervenant dans les actionneurs permettant la mise en oeuvre de la première fonction et de la deuxième fonction.Figures 3 and 4 show, showing different views of the projector device according to the assembled invention, the interactions between the various elements involved in the actuators for the implementation of the first function and the second function.

Pour la mise en oeuvre de la fonction DBL, on utilise essentiellement un secteur denté fixe 129, qui demeure immobile par rapport au cadre fixe 120, par exemple en étant directement fixé sur le cadre fixe 120. Le secteur denté fixe 129 collabore avec le deuxième pignon 114 pour entraîner le boîtier mobile 119 en rotation autour d'un axe de rotation matérialisé par les deux protubérances circulaires 124, rotation illustrée à la figure 3 par une première flèche 130. A cet effet, le secteur denté fixe est au moins partiellement circulaire. Ainsi, lorsque le deuxième moteur 112 est actif, il entraîne en rotation la vis sans fin 113, qui elle-même entraîne en rotation le deuxième pignon 114 qui évolue le long du secteur denté fixe 129 provoquant ainsi le mouvement du boîtier mobile 119.For the implementation of the DBL function, a fixed tooth sector 129 is used, which remains stationary relative to the fixed frame 120, for example by being fixed directly to the fixed frame 120. The fixed toothed sector 129 collaborates with the second pinion 114 for driving the mobile housing 119 in rotation about an axis of rotation shown by the two circular protuberances 124, rotation illustrated in Figure 3 by a first arrow 130. For this purpose, the fixed tooth sector is at least partially circular . Thus, when the second motor 112 is active, it rotates the worm 113, which itself drives in rotation the second pinion 114 which moves along the fixed tooth sector 129 thus causing the movement of the mobile housing 119.

Dans l'exemple représenté, le deuxième pignon 114 est constitué d'un premier étage 131 et d'un deuxième étage 132, le premier étage et le deuxième étage correspondant respectivement à une première roue dentée et à une deuxième roue dentée, les deux roues dentées étant coaxiales et de diamètre différent. Une telle structure permet de respecter un rapport de réduction entre la vitesse de rotation imposée par le moteur et une vitesse angulaire que doit respecter le dispositif projecteur lorsqu'il évolue en rotation pour mettre en oeuvre la fonction DBL. Par ailleurs, il est suffisant, au regard de la plage d'angles à couvrir par le dispositif projecteur mobile dans le cadre de la fonction DBL, que le secteur denté fixe 129 soit limité à un quart de cercle.In the example shown, the second gear 114 consists of a first stage 131 and a second stage 132, the first stage and the second stage respectively corresponding to a first gear wheel and a second gear wheel, the two wheels teeth being coaxial and of different diameter. Such a structure makes it possible to respect a ratio of reduction between the speed of rotation imposed by the motor and an angular speed which the projector device must respect when it evolves in rotation to implement the DBL function. Moreover, it is sufficient, with regard to the range of angles to be covered by the moving headlamp device within the framework of the DBL function, that the fixed tooth sector 129 is limited to a quarter circle.

Pour la mise en oeuvre de la première fonction, à savoir le basculement du volet pivotant 106, on active le premier moteur 110 qui, par l'intermédiaire d'une tige moteur non visible sur les figures, entraîne en rotation le premier pignon 111 qui a été préalablement, lors de l'assemblage des différents éléments constituant le dispositif projecteur, engrené dans la roue dentée 107. Cette dernière étant solidaire du volet pivotant 106, elle l'entraîne en rotation autour d'un axe de rotation matérialisé par les deux embouts circulaires 108, rotation illustrée à la figure 4 par une deuxième flèche 133.For the implementation of the first function, namely the tilting of the pivoting flap 106, activates the first motor 110 which, by means of a motor rod not visible in the figures, drives in rotation the first gear 111 which was previously, during assembly of the various elements constituting the projector device, meshing into the toothed wheel 107. The latter being secured to the pivoting flap 106, it drives in rotation about an axis of rotation materialized by the two circular tips 108, rotation illustrated in Figure 4 by a second arrow 133.

Les deux actionneurs permettant la mise en oeuvre de la première fonction et de la deuxième fonction constituent ainsi un bloc actionneur unique : le premier moteur 110 et le deuxième moteur 112, ainsi que les différents éléments intervenant dans les chaînes cinématiques permettant le mouvement des éléments cibles (le volet pivotant 106 ou le boîtier mobile en rotation 119) sont maintenus ou rattachés à différents compartiments d'un même élément, le boîtier mobile 119. Ce dernier, dans l'exemple représenté, comporte ainsi, outre les différents compartiments et éléments de maintien précédemment mentionnés, au moins un ergot de maintien 134, chaque ergot de maintien 134 étant destiné à être introduit dans une ouverture circulaire 135 du réflecteur 101, et une ouverture circulaire 136 de la plaque photométrique 105 afin de maintenir ces deux éléments.The two actuators allowing the implementation of the first function and the second function thus constitute a single actuator block: the first motor 110 and the second motor 112, as well as the various elements involved in the kinematic chains allowing the movement of the target elements. (The pivoting flap 106 or the rotating mobile housing 119) are maintained or attached to different compartments of the same element, the mobile housing 119. The latter, in the example shown, thus comprises, in addition to the various compartments and elements of maintenance previously mentioned, at least one holding pin 134, each holding pin 134 being intended to be introduced into a circular opening 135 of the reflector 101, and a circular opening 136 of the photometric plate 105 to maintain these two elements.

Ainsi, grâce au dispositif projecteur selon l'invention, le nombre de pièces intervenant dans la réalisation des deux fonctions est réduit : par l'intégration des différents éléments des deux actionneurs dans - ou sur - le boîtier mobile en rotation 119, on n'utilise pas de boîtier spécifique pour chaque actionneur ; on limite ainsi les difficultés de montage du dispositif projecteur et les risques de blocage mutuel, précédemment évoqué, des deux fonctions. Par ailleurs, le dispositif projecteur proposé dans l'invention constitue un standard qui peut remplir soit la première fonction, soit la deuxième fonction, soit les deux fonctions : il suffit, dans le premier cas et le deuxième cas, de supprimer l'actionneur qui ne sera pas utilisé, et d'adapter les moyens électroniques, ici la carte électronique 115, en conséquence. Le dispositif projecteur selon l'invention peut être utilisé aussi bien en tant que projecteur gauche que projecteur droit d'un véhicule.Thus, thanks to the projector device according to the invention, the number of parts involved in the realization of the two functions is reduced: by integrating the different elements of the two actuators in - or on - the rotating mobile housing 119, it is not possible to does not use a specific housing for each actuator; this limits the mounting difficulties of the projector device and the risk of mutual blocking, mentioned above, of the two functions. Furthermore, the projector device proposed in the invention constitutes a standard that can fulfill either the first function, or the second function, or both functions: it suffices, in the first case and the second case, to remove the actuator that will not be used, and to adapt the electronic means, here the electronic card 115, accordingly. The projector device according to the invention can be used both as a left projector and right projector of a vehicle.
