Description

La présente invention se rapporte à un dispositif lumineux d'un véhicule. Elle trouve une application particulière mais non limitative dans les véhicules automobiles.The present invention relates to a light device of a vehicle. It finds a particular but nonlimiting application in motor vehicles.

Dans le domaine des véhicules automobiles, un dispositif lumineux connu de l'homme du métier comprend un réflecteur, une plaque électronique supportant une source de lumière, un connecteur comportant deux parties, et une interface de fixation entre ladite plaque électronique et ledit réflecteur.In the field of motor vehicles, a lighting device known to those skilled in the art comprises a reflector, an electronic plate supporting a light source, a connector comprising two parts, and a fixing interface between said electronic plate and said reflector.

Un inconvénient de cet état de la technique est que la plaque électronique avec le connecteur sont montés sur le réflecteur selon l'axe vertical à l'axe du véhicule, axe du véhicule qui s'étend de l'avant vers l'arrière du véhicule. Selon ce montage vertical, il y a un risque que les deux parties du connecteur ne soient pas bien connectées entre elles lors du montage, ou qu'elles ne restent pas bien connectées entre elles lorsque le véhicule roule.A drawback of this state of the art is that the electronic plate with the connector are mounted on the reflector along the vertical axis to the axis of the vehicle, the axis of the vehicle which extends from the front to the rear of the vehicle. . According to this vertical assembly, there is a risk that the two parts of the connector will not be well connected to each other during assembly, or that they will not remain well connected to each other when the vehicle is moving.

Dans ce contexte, la présente invention vise à proposer un dispositif lumineux qui permet de résoudre l'inconvénient mentionné.In this context, the present invention aims to provide a lighting device which makes it possible to solve the mentioned drawback.

A cet effet, l'invention propose un dispositif lumineux d'un véhicule comprenant un réflecteur, une plaque électronique supportant une source de lumière, un connecteur comportant deux parties, et une interface de fixation entre ladite plaque électronique et ledit réflecteur, caractérisé en ce que ladite interface de fixation comprend des butées coopérant avec des butées d'une des deux parties dudit connecteur.To this end, the invention provides a lighting device for a vehicle comprising a reflector, an electronic plate supporting a light source, a connector comprising two parts, and a fastening interface between said electronic plate and said reflector, characterized in that that said fixing interface comprises stops cooperating with stops of one of the two parts of said connector.

Ainsi, comme on va le voir en détail ci-après, les butées de l'interface de fixation en coopérant avec les butées du connecteur permettent d'assurer une connexion fiable en garantissant le bon contact du connecteur. Ainsi, cela évite d'avoir un contrôle supplémentaire pour savoir si la connexion entre les deux parties du connecteur est réalisée correctement.Thus, as will be seen in detail below, the stops of the fixing interface by cooperating with the stops of the connector make it possible to ensure a reliable connection while guaranteeing good contact of the connector. Thus, this avoids having an additional check to know if the connection between the two parts of the connector is made correctly.

Selon des modes de réalisation non limitatifs, le dispositif lumineux d'un véhicule peut comporter en outre une ou plusieurs caractéristiques supplémentaires prises seules ou selon toutes les combinaisons techniquement possibles, parmi les suivantes.According to non-limiting embodiments, the lighting device of a vehicle may further include one or more additional characteristics taken alone or in any technically possible combination, among the following.

Selon un mode de réalisation non limitatif, ladite interface de fixation comprend un fût de vissage configuré pour être en regard d'un orifice dudit réflecteur et recevoir une vis.According to a nonlimiting embodiment, said fixing interface comprises a screwing shank configured to be opposite an orifice of said reflector and to receive a screw.

Dans des exemples non limitatifs, le dispositif lumineux 1 fait partie :

  • d'un projecteur, et/ou
  • d'un feu de signalisation, et/ou,
  • d'un feu de brouillard, et/ou
  • d'un feu arrière, ou
  • d'un dispositif d'éclairage intérieur.
In non-limiting examples, the lighting device 1 is part of:
  • a projector, and / or
  • a traffic light, and / or,
  • a fog light, and / or
  • a rear light, or
  • an interior lighting device.

Dans un exemple non limitatif, un projecteur peut comprend un ou plusieurs dispositifs lumineux 1. Il est en de même pour un feu de signalisation, un feu de brouillard, un feu arrière, un dispositif d'éclairage d'intérieur.In a non-limiting example, a headlight can include one or more light devices 1. The same is true for a signal light, a fog light, a rear light, an interior lighting device.

Dans des modes de réalisation non limitatifs, le dispositif lumineux 1 est adapté pour former tout ou partie d'un faisceau de signalisation (type feu diurne, feu de position, feu antibrouillard, clignotant), et/ou d'un faisceau d'éclairage (feu de route dit « High Beam » en langage anglo-saxon, feu de croisement dit « Low Beam » en langage anglo-saxon).In non-limiting embodiments, the light device 1 is adapted to form all or part of a signaling beam (daytime running light, position light, fog light, flashing light), and / or a lighting beam (high beam called "High Beam" in Anglo-Saxon language, low beam called "Low Beam" in Anglo-Saxon language).

Tel qu'illustré sur les figures 1 à 3, dans un mode de réalisation non limitatif, le dispositif lumineux 1 comprend :

  • un réflecteur 10,
  • une plaque électronique 11 supportant une source de lumière 12,
  • un connecteur 13 comportant deux parties 130, 131,
  • une interface de fixation 14 entre la plaque électronique 11 et le réflecteur 10.
As shown on figures 1 to 3 , in a non-limiting embodiment, the lighting device 1 comprises:
  • a reflector 10,
  • an electronic plate 11 supporting a light source 12,
  • a connector 13 comprising two parts 130, 131,
  • a fixing interface 14 between the electronic plate 11 and the reflector 10.

Dans un mode de réalisation non limitatif, le dispositif lumineux 1 comprend une liaison glissière 104-144 entre le réflecteur 10 et l'interface de fixation 14. Le dispositif lumineux 1 comprend un axe d'assemblage vertical Z qui est perpendiculaire à un axe véhicule Y, ledit axe véhicule Y étant l'axe qui s'étend de l'avant à l'arrière du véhicule automobile 2. Ainsi, le réflecteur 10, la plaque électronique 11, et l'interface de fixation 14 s'assemblent entre eux verticalement selon ledit axe d'assemblage vertical Z. Le montage selon l'axe d'assemblage vertical Z permet d'avoir une bonne focalisation de la source de lumière 12 sur le réflecteur 10. L'assemblage en Z présente moins de dispersions qu'un assemblage en Y car la mise en position de la source de lumière 12 est plus précise qu'elle ne l'est en Y. Par ailleurs, contrairement à un assemblage en Y, il n'y a pas de jeu d'assemblage qui augmente les dispersions potentielles.In a non-limiting embodiment, the lighting device 1 comprises a sliding link 104-144 between the reflector 10 and the fixing interface 14. The lighting device 1 comprises a vertical assembly axis Z which is perpendicular to a vehicle axis. Y, said vehicle axis Y being the axis which extends from the front to the rear of the motor vehicle 2. Thus, the reflector 10, the electronic plate 11, and the fixing interface 14 are assembled together vertically along said vertical assembly axis Z. The assembly along the vertical assembly axis Z makes it possible to have a good focusing of the light source 12 on the reflector 10. The Z assembly has less dispersions than an assembly in Y because the positioning of the light source 12 is more precise than it is in Y. Moreover, unlike a assembly in Y, there is no assembly clearance which increases potential dispersions.

Les éléments du dispositif lumineux 1 sont décrits en détail ci-après.The elements of the lighting device 1 are described in detail below.

Tel qu'illustré sur les figures 4a et 4b, le réflecteur 10 comprend une base 100 configurée pour se fixer sur la plaque électronique 11, notamment à la partie primaire 112a du dissipateur thermique 112 décrit plus loin, et une partie optique 101 configurée pour réfléchir les rayons lumineux R de la source de lumière 12 décrite plus loin. Le réflecteur 10 comprend en outre un orifice 100d à travers lequel une vis 4 peut passer. L'orifice 100d est configuré pour être disposé en regard d'un fût de vissage 143 de l'interface de fixation 14 décrite plus loin. Dans un mode de réalisation non limitatif, le réflecteur 10 est en liaison glissière avec l'interface de fixation 14. A cet effet, il comprend une glissière 104 configurée pour coopérer avec un coulisseau 144 de l'interface de fixation 14. Dans un mode de réalisation non limitatif, le réflecteur 10 comprend en outre au moins un détrompeur 102, dit poka yoke, pour positionner ledit réflecteur 10 par rapport à la plaque électronique 11. Cela permet de focaliser la source de lumière 12 sur le réflecteur 10. Le détrompeur 102 est configuré pour coopérer avec un trou 104 de l'interface de fixation 14 décrite plus loin. Dans un exemple non limitatif, il comprend deux détrompeurs 102. Dans un exemple non limitatif, le détrompeur 102 est un ergot configuré pour s'insérer dans un trou 104 de l'interface de fixation 14. Dans un exemple non limitatif, le détrompeur 102 a une forme en équerre. Cela permet de limiter la largeur du support électronique 110 et optimiser la panélisation du support électronique 110.As shown on figures 4a and 4b , the reflector 10 comprises a base 100 configured to be fixed to the electronic plate 11, in particular to the primary part 112a of the heat sink 112 described below, and an optical part 101 configured to reflect the light rays R from the light source 12 described later. The reflector 10 further comprises an orifice 100d through which a screw 4 can pass. The orifice 100d is configured to be placed opposite a screwing shank 143 of the fixing interface 14 described below. In a non-limiting embodiment, the reflector 10 is in sliding connection with the fixing interface 14. For this purpose, it comprises a slide 104 configured to cooperate with a slide 144 of the fixing interface 14. In one embodiment of non-limiting embodiment, the reflector 10 further comprises at least one keying 102, called poka yoke, for positioning said reflector 10 relative to the electronic plate 11. This makes it possible to focus the light source 12 on the reflector 10. The keying device 102 is configured to cooperate with a hole 104 of the fixing interface 14 described later. In a non-limiting example, it comprises two keying devices 102. In a non-limiting example, the keying device 102 is a lug configured to fit into a hole 104 of the fixing interface 14. In a non-limiting example, the keying 102 has a shape in square. This makes it possible to limit the width of the electronic medium 110 and to optimize the paneling of the electronic medium 110.

Tel qu'illustré sur la figure 5a, la plaque électronique 11 comprend un support électronique 110 et un dissipateur thermique 112. Ces éléments sont décrits ci-après.As shown on figure 5a , the electronic plate 11 comprises an electronic support 110 and a heat sink 112. These elements are described below.

Tel qu'illustré sur la figure 5a, le support électronique 110 est adapté pour accueillir et relier électriquement un ensemble de composants électroniques entre eux. En particulier, il accueille la source de lumière 12 et un dispositif de pilotage 15 de l'alimentation électrique de la source de lumière. Le support électronique 110, et en particulier ses composants électroniques dont le dispositif de pilotage 15 et la source de lumière 12, génère de la chaleur au cours de son fonctionnement qu'il convient d'évacuer hors du dispositif lumineux 1. L'évacuation de cette chaleur est assurée par le dissipateur thermique 112. Dans un mode de réalisation non limitatif, le support électronique 110 est une carte à circuit imprimé, autrement appelée carte PCBA (« Printed Circuit Board Assembly » en anglais). Dans un autre mode de réalisation non limitatif, le support électronique 110 est une carte flexible appelé « flex PCB » ou « circuit flex » (« flexible printed circuit » en anglais). Dans un mode de réalisation non limitatif, le support électronique 110 comprend un orifice 110d à travers duquel une vis 4 peut passer et configuré pour être disposé en regard de l'orifice 100d du réflecteur 10.As shown on figure 5a , the electronic support 110 is suitable for receiving and electrically connecting a set of electronic components together. In particular, it accommodates the light source 12 and a device 15 for controlling the power supply to the light source. The electronic support 110, and in particular its electronic components including the control device 15 and the light source 12, generates heat during its operation which must be evacuated out of the lighting device 1. The evacuation of this heat is provided by the heat sink 112. In a non-limiting embodiment, the electronic support 110 is a printed circuit board, otherwise called a PCBA (“Printed Circuit Board Assembly”) card. In another nonlimiting embodiment, the electronic support 110 is a flexible card called “flex PCB” or “flex circuit” (“flexible printed circuit” in English). In a non-limiting embodiment, the electronic support 110 comprises an orifice 110d through which a screw 4 can pass and configured to be placed opposite the orifice 100d of the reflector 10.

Tel qu'illustré sur la figure 1, la source de lumière 12 est adaptée pour émettre des rayons lumineux R. Ces rayons lumineux R coopèrent avec le réflecteur 10 de sorte à former un faisceau lumineux F. Dans un mode de réalisation non limitatif, la source de lumière 12 est une source de lumière à semi-conducteur. Dans un mode de réalisation non limitatif, la source de lumière 12 à semi-conducteur fait partie d'une diode électroluminescente. Par diode électroluminescente, on entend tout type de diodes électroluminescentes, que ce soit dans des exemples non limitatifs des LED (« Light Emitting Diode »), une OLED (« Organic LED ») ou une AMOLED (« Active-Matrix-Organic LED »), ou encore une FOLED (« Flexible OLED »). Tel qu'illustré sur la figure 5a, dans un mode de réalisation non limitatif illustrée, la source de lumière 12 est fixée sur le support électronique 110 lui même fixé sur le dissipateur thermique 112. La source de lumière 12 est disposée à distance du dispositif de pilotage 15. Dans un mode de réalisation non limitatif, le dispositif de pilotage 15 est également fixé sur le support électronique 110.As shown on figure 1 , the light source 12 is adapted to emit light rays R. These light rays R cooperate with the reflector 10 so as to form a light beam F. In a non-limiting embodiment, the light source 12 is a source of light. semiconductor light. In a non-limiting embodiment, the semiconductor light source 12 forms part of a light emitting diode. By light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LEDs (“Light Emitting Diode”), an OLED (“Organic LED”) or an AMOLED (“Active-Matrix-Organic LED”). ), or a FOLED (“Flexible OLED”). As shown on figure 5a , in a non-limiting embodiment illustrated, the light source 12 is fixed on the electronic support 110 itself fixed on the heat sink 112. The light source 12 is disposed at a distance from the control device 15. In one embodiment non-limiting embodiment, the control device 15 is also fixed on the electronic support 110.

Le dissipateur thermique 112 est configuré pour évacuer la chaleur dégagée par le dispositif lumineux 1, notamment par sa source de lumière 12 et par le dispositif de pilotage 15. Tel qu'illustré sur la figure 5b, il comprend une partie primaire 112a et une partie secondaire 112b qui s'étend perpendiculairement par rapport à la partie primaire 112a. La partie primaire 112a et la partie secondaire 112b sont reliées par un coude 112c. Elles servent toutes les deux à dissiper la chaleur. La partie primaire 112a est configurée pour se plaquer contre le support électronique 10, et la partie secondaire 112b est configurée pour être en regard dudit connecteur 13 lorsque le dispositif lumineux 1 est monté. La partie secondaire 112b est positionnée à l'arrière et vers le bas en raison de contraintes d'encombrement. Par ailleurs, la partie secondaire 112 peut accueillir un dissipateur thermique additionnel dans les configurations de High Beam. Dans un mode de réalisation non limitatif, le dissipateur thermique 112 comprend un orifice 112d à travers duquel une vis 4 peut passer, et configuré pour être disposé en regard de l'orifice 100d du réflecteur 10 et de l'orifice 110d du support électronique 110. Tel qu'illustré sur la figure 5b, dans un mode de réalisation non limitatif, le dissipateur thermique 112 comprend au moins une fenêtre 112e configuré pour coopérer avec un détrompeur 102 du réflecteur 10. Dans un exemple non limitatif, il comprend deux fenêtres 112e. Dans un exemple non limitatif, les fenêtres 112e ont une forme en équerre. On notera que le vissage selon l'axe d'assemblage vertical Z permet de s'affranchir des dispersions de réalisation du pliage réalisé sur le dissipateur thermique 12 pour obtenir la partie primaire 112a et la partie secondaire 112b, contrairement à un vissage selon l'axe véhicule Y. Le vissage selon l'axe véhicule Y se fait en effet, sur la partie secondaire 112b alors que le support électronique 110 est fixé sur la partie primaire 112a. Dans ce cas, la dispersion de réalisation du pliage a un impact sur l'orientation finale du support électronique 110.The heat sink 112 is configured to remove the heat given off by the lighting device 1, in particular by its light source 12 and by the control device 15. As illustrated in the figure. figure 5b , it comprises a primary part 112a and a secondary part 112b which extends perpendicularly relative to the primary part 112a. The primary part 112a and the secondary part 112b are connected by an elbow 112c. They both serve to dissipate heat. The primary part 112a is configured to press against the electronic support 10, and the secondary part 112b is configured to be opposite said connector 13 when the lighting device 1 is mounted. The secondary part 112b is positioned at the rear and towards the bottom due to space constraints. In addition, the secondary part 112 can accommodate an additional heat sink in High Beam configurations. In a non-limiting embodiment, the heat sink 112 comprises an orifice 112d through which a screw 4 can pass, and configured to be disposed opposite the orifice 100d of the reflector 10 and the orifice 110d of the electronic support 110 As illustrated on the figure 5b , in a non-limiting embodiment, the heat sink 112 comprises at least one window 112e configured to cooperate with a polarizer 102 of the reflector 10. In a non-limiting example, it comprises two windows 112e. In a non-limiting example, the windows 112e have a square shape. It will be noted that the screwing along the vertical assembly axis Z makes it possible to overcome the dispersions in the production of the bending carried out on the heat sink 12 to obtain the primary part 112a and the secondary part 112b, unlike a screwing according to the vehicle axis Y. The screwing along the vehicle axis Y is in fact done on the secondary part 112b while the electronic support 110 is fixed on the primary part 112a. In this case, the dispersion in the production of the folding has an impact on the final orientation of the electronic medium 110.

Tel qu'illustré sur les figures 6a et 6b, le connecteur 13 comprend deux parties 130 et 131. Dans un mode de réalisation non limitatif, la partie 130 est une partie mâle tandis que la partie 131 est une partie femelle. La partie mâle 130 et la partie femelle 131 se connectent entre elles selon l'axe d'assemblage vertical Z. Le connecteur 13 comprend en outre un élément de maintien 132 de fils de connexion électriques 3 (illustrés sur la figure 1) qui relient les composants électroniques (dont la source de lumière 12 et le dispositif de pilotage 15) du support électronique 110 avec une alimentation électrique (non illustrée) du véhicule automobile. Dans un mode de réalisation non limitatif illustré, cet élément de maintien 132 est configuré pour se clipper dans la partie femelle 131. Dans un autre mode de réalisation non limitatif, cet élément de maintien 132 fait partie de la partie femelle 131. Le connecteur 13 comprend deux butées 133 configurées pour venir en contact avec l'interface de connexion 14 décrite plus loin, notamment avec ses deux butées 140. Dans un mode de réalisation non limitatif, les deux butées 133 font partie de l'élément de maintien 132. Ces deux butées 133 sont reliées à un corps 132a de l'élément de maintien 132, en particulier elles sont reliées à chaque extrémité de cet élément de maintient 132.As shown on figures 6a and 6b , the connector 13 comprises two parts 130 and 131. In a non-limiting embodiment, the part 130 is a male part while the part 131 is a female part. The male part 130 and the female part 131 are connected to each other along the vertical assembly axis Z. The connector 13 further comprises a holding element 132 for electrical connection wires 3 (illustrated in FIG. figure 1 ) which connect the electronic components (including the light source 12 and the control device 15) of the electronic support 110 with a power supply (not shown) of the motor vehicle. In a non-limiting embodiment illustrated, this retaining element 132 is configured to clip into the female part 131. In another non-limiting embodiment, this retaining element 132 is part of the female part 131. The connector 13 comprises two stops 133 configured to come into contact with the connection interface 14 described below, in particular with its two stops 140. In a non-limiting embodiment, the two stops 133 form part of the holding element 132. These two stops 133 are connected to a body 132a of the holding element 132, in particular they are connected to each end of this holding element 132.

Dans un mode de réalisation non limitatif, l'interface de fixation 14 est une pièce rapportée. Tel qu'illustré sur la figure 7, elle comprend des butées 140 configurées pour coopérer avec les butées 133 d'une des deux parties 130, 131 du connecteur 131. Dans un mode de réalisation non limitatif, elle comprend deux butées 140. Dans un mode de réalisation non limitatif, l'interface de fixation 14 comprend en outre une plaque de base 141 qui s'étend selon un plan A-A' (illustré sur la figure par une ligne en pointillés), et les butées 140 s'étendent selon un plan parallèle B-B' (illustré sur la figure par une ligne en pointillés) à l'axe A-A'. Elles sont ainsi décalées par rapport à la plaque de base 141 selon l'axe Z. La position du plan de la plaque de base 141 est liée à la hauteur du fût de vissage 143. La position du plan des butées 140 est liée à la hauteur du connecteur 13 et de l'élément de maintien 132. Les butées 140 sont reliées à la plaque de base 141 par une plaque de liaison 142 perpendiculaire à la plaque de base 141. La plaque de liaison 142 s'étend le long de l'axe d'assemblage vertical Z. Dans un mode de réalisation non limitatif, l'interface de fixation 14 comprend en outre un fût de vissage 143 configuré pour être en regard de l'orifice 100d du réflecteur 10 et pour recevoir la vis 4. La vis 4 permet de visser l'ensemble interface de fixation 14, réflecteur 10 et plaque électronique 11. Le fût de vissage 143 prend naissance à partir de la plaque de base 141 et s'étend perpendiculairement à elle, à savoir selon l'axe d'assemblage vertical Z. L'interface de fixation 14 comprend en outre de coulisseau 144 configuré pour coulisser dans la glissière 104 du réflecteur 10 de sorte à positionner l'interface de fixation 14 par rapport au réflecteur 10. Le coulissement du coulisseau 144 s'effectue perpendiculairement à l'axe d'assemblage vertical Z. Dans un mode de réalisation non limitatif illustré, le coulisseau 144 s'étend de part et d'autre du fût de vissage 143.In a non-limiting embodiment, the fixing interface 14 is an attached part. As shown on figure 7 , it comprises stops 140 configured to cooperate with the stops 133 of one of the two parts 130, 131 of the connector 131. In a non-limiting embodiment, it comprises two stops 140. In a non-limiting embodiment, the fixing interface 14 further comprises a base plate 141 which extends in a plane AA '(illustrated in the figure by a dotted line), and the stops 140 extend in a plane parallel BB' (illustrated in the figure by a dotted line) to the axis A-A '. They are thus offset with respect to the base plate 141 along the Z axis. The position of the plane of the base plate 141 is linked to the height of the screw barrel 143. The position of the plane of the stops 140 is linked to the height. height of the connector 13 and of the retaining element 132. The stops 140 are connected to the base plate 141 by a connecting plate 142 perpendicular to the base plate 141. The connecting plate 142 extends along the length 'vertical assembly axis Z. In a non-limiting embodiment, the fixing interface 14 further comprises a screwing shank 143 configured to be opposite the orifice 100d of the reflector 10 and to receive the screw 4. The screw 4 enables the assembly of the fixing interface 14, reflector 10 and electronic plate 11 to be screwed.

The fixing interface 14 further comprises slider 144 co nfigured to slide in the slide 104 of the reflector 10 so as to position the fixing interface 14 relative to the reflector 10. The sliding of the slider 144 takes place perpendicular to the vertical assembly axis Z. In one embodiment non-limiting illustrated, the slide 144 extends on either side of the screw barrel 143.

La figure 8 illustre l'interface de fixation 14 qui coopère avec le connecteur 13. Comme on peut le voir sur la figure, les butées 133 du connecteur 13 sont en appui sur les butées 140 de l'interface de connexion 14. Par ailleurs, le connecteur 13 est disposé parallèlement à la plaque de liaison 142 de l'interface de fixation 14. En particulier sa partie femelle 131 se trouve en regard de ladite plaque de liaison 142.The figure 8 illustrates the fixing interface 14 which cooperates with the connector 13. As can be seen in the figure, the stops 133 of the connector 13 bear against the stops 140 of the connection interface 14. Furthermore, the connector 13 is arranged parallel to the connecting plate 142 of the fixing interface 14. In particular its female part 131 is located opposite said connecting plate 142.

Le montage des éléments du dispositif lumineux 1 est réalisé comme suit par un opérateur ou une machine outil. Dans l'exemple non limitatif qui suit, il est réalisé par un opérateur.The elements of the lighting device 1 are assembled as follows by an operator or a machine tool. In the non-limiting example which follows, it is carried out by an operator.

Dans une première étape illustrée sur les figures 6a et 6b, l'opérateur assemble les deux parties 130, 131 du connecteur 13. La partie mâle 130 s'emmanche dans la partie femelle 131. De plus, si l'élément de maintien 132 est indépendant de la partie mâle 131, l'opérateur clipse l'élément de maintien 132 avec la partie femelle 131.In a first step illustrated on the figures 6a and 6b , the operator assembles the two parts 130, 131 of the connector 13. The male part 130 fits into the female part 131. Moreover, if the holding element 132 is independent of the male part 131, the operator clips the retaining element 132 with the female part 131.

Dans une deuxième étape illustrée sur la figure 9, l'opérateur positionne le connecteur 13 sur la plaque électronique 11 selon l'axe d'assemblage vertical Z, en particulier il maintient le connecteur 13 en contact avec le support électronique 110 en appuyant dessus avec une force de pression 50. La partie mâle 131 est en contact avec le support électronique 110.In a second step illustrated on the figure 9 , the operator positions the connector 13 on the electronic plate 11 along the vertical assembly axis Z, in particular he maintains the connector 13 in contact with the electronic support 110 by pressing on it with a pressing force 50. The male part 131 is in contact with the electronic support 110.

Dans une troisième étape illustrée sur la figure 10, le réflecteur 10 et l'interface de fixation 14 sont assemblés ensemble au moyen de la liaison glissière 104-144. A cet effet, l'opérateur pousse en translation le coulisseau 144 de l'interface de fixation 14 dans la glissière 104 du réflecteur 10 selon l'axe véhicule Y, avec une force de pression 51. Lorsque le réflecteur 10 est ainsi assemblé avec l'interface de fixation 14, son orifice 100d se trouve en regard du fût de vissage 143 de l'interface de fixation 14. On notera que les étapes une à trois ci-dessus peuvent être réalisées dans n'importe quel ordre.In a third step illustrated on figure 10 , the reflector 10 and the fixing interface 14 are assembled together by means of the sliding link 104-144. To this end, the operator pushes the slide 144 of the fixing interface 14 in translation in the slide 104 of the reflector 10 along the vehicle axis Y, with a pressure force 51. When the reflector 10 is thus assembled with the The fixing interface 14, its orifice 100d is located opposite the screwing shank 143 of the fixing interface 14. It will be noted that steps one to three above can be carried out in any order.

Dans une quatrième étape illustrée sur la figure 11, l'opérateur assemble l'ensemble plaque électronique 11-connecteur 13 avec l'ensemble réflecteur 10-interface de fixation 14. Sur la figure 11 est également représenté les fils de connexion électriques 3. Ainsi, pour assembler l'ensemble, l'opérateur positionne l'ensemble réflecteur 10-interface de fixation 14 sur l'ensemble plaque électronique 11-connecteur 13 selon l'axe d'assemblage vertical Z au moyen des détrompeurs 102 du réflecteur 10 qui s'insèrent dans les trous 104 de l'interface de fixation 14 de sorte que :

  • l'orifice 100d du réflecteur 10 se trouve en regard de l'orifice 110d du support électronique 110 de la plaque électronique 11,
  • l'orifice 100d du réflecteur 10 se trouve en regard du fût de vissage 143 de l'interface de fixation 14,
  • le support électronique 110 de la plaque électronique 11 se trouve en regard de la base 100 du réflecteur 10,
  • le connecteur 13, en particulier sa partie femelle 131, se trouve en regard de l'interface de fixation 14, en particulier de sa plaque de liaison 142
  • le support électronique 110 est en contact du connecteur 13, en particulier de sa partie mâle 130,
  • les butées 133 du connecteur 13 viennent en appui sur les butées 140 de l'interface de fixation 14.
In a fourth step illustrated on figure 11 , the operator assembles the electronic plate 11-connector 13 assembly with the reflector 10-mounting interface assembly 14. On the figure 11 The electrical connection wires 3 are also shown. Thus, to assemble the assembly, the operator positions the reflector 10-fixing interface assembly 14 on the electronic plate 11-connector 13 assembly along the vertical assembly axis Z by means of the polarizers 102 of the reflector 10 which fit into the holes 104 of the fixing interface 14 so that:
  • the orifice 100d of the reflector 10 is located opposite the orifice 110d of the electronic support 110 of the electronic plate 11,
  • the orifice 100d of the reflector 10 is located opposite the screwing barrel 143 of the fixing interface 14,
  • the electronic support 110 of the electronic plate 11 is located opposite the base 100 of the reflector 10,
  • the connector 13, in particular its female part 131, is located opposite the fixing interface 14, in particular its connecting plate 142
  • the electronic support 110 is in contact with the connector 13, in particular with its male part 130,
  • the stops 133 of the connector 13 bear against the stops 140 of the fixing interface 14.

Dans une cinquième étape illustrée sur la figure 1, l'opérateur 4 insère une vis 4 dans les orifices 112d, 100d et 110d et visse la vis 4 dans le fût de vissage 143 en exerçant une force de pression 52. Pendant qu'il effectue le vissage, il maintient l'ensemble du dispositif lumineux 1 en sandwich entre ses doigts. Le vissage permet d'exercer une pression sur la plaque électronique 11 de sorte que :

  • les butées 140 de l'interface de fixation 14 appuient bien sur les butées 133 du connecteur 13. Ainsi, la partie femelle 131 et la partie mâle 130 du connecteur 13 sont bien emmanchées ensemble. Il n'y a ainsi pas de mauvais contact électrique dans le connecteur 13,
  • la partie mâle 130 du connecteur 13 soit bien en contact avec le support électronique 110. Il n'y a ainsi pas de mauvais contact électrique entre le connecteur 13 et le support électronique 110.
In a fifth step illustrated on figure 1 , the operator 4 inserts a screw 4 in the holes 112d, 100d and 110d and screws the screw 4 in the screwing barrel 143 by exerting a pressure force 52. While carrying out the screwing, he maintains the whole of the screw. light device 1 sandwiched between his fingers. Screwing makes it possible to exert pressure on the electronic plate 11 so that:
  • the stops 140 of the fixing interface 14 bear well on the stops 133 of the connector 13. Thus, the female part 131 and the male part 130 of the connector 13 are properly fitted together. There is thus no bad electrical contact in connector 13,
  • the male part 130 of the connector 13 is in good contact with the electronic support 110. There is thus no bad electrical contact between the connector 13 and the electronic support 110.

Ainsi, tel qu'illustré sur la figure 2, l'ensemble des éléments du dispositif lumineux 1 est assemblé.Thus, as illustrated on figure 2 , all the elements of the lighting device 1 are assembled.

Bien entendu la description de l'invention n'est pas limitée aux modes de réalisation décrits ci -dessus et au domaine décrit ci-dessus. Ainsi, dans un autre mode de réalisation non limitatif non illustré, le dispositif de pilotage 15 n'est pas fixé au support électronique 110 mais est déporté.Of course, the description of the invention is not limited to the embodiments described above and to the field described above. Thus, in another nonlimiting embodiment which is not illustrated, the control device 15 is not fixed to the electronic support 110 but is deported.

Ainsi, l'invention décrite présente notamment les avantages suivants :

  • elle simplifie le processus d'assemblage de l'ensemble des éléments du dispositif lumineux 1,
  • elle assure un bon assemblage des éléments du dispositif lumineux 1,
  • grâce aux butées 133 et 140, elle évite à l'opérateur de devoir ré-appuyer de nouveau avec ses doigts sur le connecteur 13 pour essayer d'assurer une bonne connexion entre les deux parties 130, 131 du connecteur 13 et entre le connecteur 13 et le support électronique 110,
  • elle évite que les deux parties 130, 131 du connecteur 13 soient mal emmanchées entre elles,
  • elle assure que les deux parties 130, 131 du connecteur 13 restent solidaires l'une de l'autre au cours du montage et lorsque le véhicule roule,
  • elle évite d'avoir un assemblage selon l'axe véhicule Y. Ainsi, on évite d'avoir un fût de vissage dans la partie optique 101 du réflecteur 10 qui entraîne des problèmes de retassures et des problèmes de focalisation de la source de lumière 12 sur le réflecteur 10. Par ailleurs, on évite des dispersions de positionnement de la source de lumière 12,
  • grâce à l'assemblage selon l'axe d'assemblage vertical Z, elle assure ainsi une bonne focalisation optique entre la source de lumière 12 sur le réflecteur 10.
Thus, the invention described has the following advantages in particular:
  • it simplifies the assembly process of all the elements of the lighting device 1,
  • it ensures a good assembly of the elements of the lighting device 1,
  • thanks to the stops 133 and 140, it prevents the operator from having to press again with his fingers on the connector 13 to try to ensure a good connection between the two parts 130, 131 of the connector 13 and between the connector 13 and electronic support 110,
  • it prevents the two parts 130, 131 of the connector 13 from being poorly fitted together,
  • it ensures that the two parts 130, 131 of the connector 13 remain integral with one another during assembly and when the vehicle is moving,
  • it avoids having an assembly along the vehicle axis Y. Thus, it avoids having a screw barrel in the optical part 101 of the reflector 10 which causes sink problems and focusing problems of the light source 12 on the reflector 10. Furthermore, positioning dispersions of the light source 12 are avoided,
  • thanks to the assembly along the vertical assembly axis Z, it thus ensures good optical focusing between the light source 12 on the reflector 10.
