Description

DESCRIPTION  DESCRIPTION
Titre de l'invention : Bloc optique pour véhicule automobile pourvu d'un masque fixé sur une armature Title of the invention: Optical unit for a motor vehicle provided with a mask fixed on a frame
Domaine technique Technical area
La présente invention concerne d'une manière générale le domaine des systèmes d'éclairage et de signalisation pour véhicules automobiles.  The present invention relates generally to the field of lighting and signaling systems for motor vehicles.
Elle concerne en particulier un bloc optique d'éclairage ou de signalisation pour véhicule automobile.  It relates in particular to an optical lighting or signaling unit for a motor vehicle.
Technique antérieure Prior art
Un tel bloc optique comporte classiquement au moins une armature destinée à être fixée sur la structure du véhicule et sur lequel est monté, directement ou par l'intermédiaire d'un support dédié, au moins un module lumineux apte à assurer une fonction photométrique d'éclairage comme par exemple un feu de position (dénommé également veilleuse ou bien lanterne), ou une fonction photométrique de signalisation comme par exemple un feu de recul, un feu STOP, un feu clignotant indicateur de changement de direction ou bien encore un feu diurne couramment désigné sous l'acronyme anglais DRL (Daytime Running Light) et s'allumant automatiquement lorsque le véhicule se déplace vers l'avant afin d'accroître sa visibilité dans des conditions de lumière du jour.  Such an optical unit conventionally comprises at least one frame intended to be fixed to the structure of the vehicle and on which is mounted, directly or via a dedicated support, at least one light module capable of ensuring a photometric function of lighting such as a position light (also known as a night light or lantern), or a photometric signaling function such as a reversing light, a STOP light, a flashing direction indicator light or even a daytime running light designated by the English acronym DRL (Daytime Running Light) and lights up automatically when the vehicle is moving forward to increase its visibility in daylight conditions.
Chaque module lumineux comprend classiquement au moins une source lumineuse constituée par exemple par une ampoule halogène ou une diode électroluminescente ainsi qu'un élément optique tel qu'un réflecteur ou un guide de lumière et apte à modifier le trajet des rayons lumineux lui parvenant en direction de l'espace à illuminer.  Each light module conventionally comprises at least one light source constituted for example by a halogen bulb or a light-emitting diode as well as an optical element such as a reflector or a light guide and capable of modifying the path of the light rays reaching it in the direction space to illuminate.
Il est également connu, en particulier de la demande de brevet française FR 3056483 Al, d'équiper un tel bloc optique d'un masque fixé à l'armature et destiné à dissimuler aux yeux d'un observateur situé à l'extérieur du véhicule certains éléments de cette armature et/ou du ou des modules lumineux tout en assurant une partie du style de ce bloc optique. La fixation du masque sur l'armature est réalisée classiquement par l'intermédiaire de moyens comportant au moins un organe de fixation prévu sur l'un de ces deux éléments et coopérant par vissage avec u n orifice pratiqué sur l'autre de ces éléments. It is also known, in particular from French patent application FR 3056483 A1, to equip such an optical unit with a mask fixed to the frame and intended to conceal from the eyes of an observer located outside the vehicle. certain elements of this frame and / or of the light module or modules while ensuring part of the style of this optical unit. The mask is fixed to the frame conventionally by means comprising at least one fixing member provided on one of these two elements and cooperating by screwing with an orifice made on the other of these elements.
Dans la demande de brevet susvisée, l'organe de fixation comprend un fût tronconique prenant racine sur l'armature et étant pourvu d'un perçage dans lequel on vient visser une vis auto-taraudeuse ayant préalablement traversé un orifice circulaire correspondant pratiqué dans une paroi portée par le masque.  In the aforementioned patent application, the fixing member comprises a frustoconical barrel taking root on the frame and being provided with a hole in which one comes to screw a self-tapping screw having previously passed through a corresponding circular orifice made in a wall carried by the mask.
Le perçage du fût n'étant généralement pas taraudé (un tel taraudage devant en effet être systématiquement réalisé post injection), ce dernier n'accueille pas facilement la vis au débit de l'opération de vissage et à tendance à reculer vis-à-vis de l'orifice (le masque et l'armature s'écartant alors légèrement l'un de l'autre).  The drilling of the barrel is not generally tapped (such a tapping having in fact to be systematically carried out post injection), the latter does not easily receive the screw at the rate of the screwing operation and tends to move back towards screw of the orifice (the mask and the frame then deviating slightly from each other).
Afin de permettre la prise de la vis dans le perçage du fût, l'opérateur en charge du montage doit exercer, avec l'une de ses mains et concomitamment au vissage, un contre-effort sur l'élément portant ce fût de sorte à éviter son recul .  In order to allow the screw to be caught in the drilling of the barrel, the operator in charge of assembly must exert, with one of his hands and concomitantly with the screwing, a counter-force on the element carrying this barrel so as to avoid its recoil.
Cette manipulation complexifie le montage et a tendance à laisser des traces de doigts sur le masque ou l'armature ce qui impacte négativement le niveau de qualité perçue par les usagers.  This manipulation complicates the mounting and tends to leave fingerprints on the mask or frame, which negatively impacts the level of quality perceived by users.
Exposé de l'invention Statement of the invention
La présente invention vise donc à améliorer la situation.  The present invention therefore aims to improve the situation.
Elle propose à cet effet un bloc optique de signalisation et/ou d'éclairage pour véhicule automobile comportant une armature, u n module optique monté sur ladite armature et comprenant au moins un dispositif lumineux apte à assurer au moins une fonction photométrique, ainsi qu'un masque fixé sur ladite armature par l'intermédiaire de moyens de fixation et étant apte à dissimuler une partie dudit module optique à la vue d'un observateur, lesdits moyens de fixation entre le masque et l'armature comportant au moins un fût porté par l'un de ces éléments et étant pourvu d'un perçage dans lequel est vissé une vis ayant préalablement traversé un orifice correspondant pratiqué dans une paroi portée par l'autre élément ; caractérisé en ce que ledit bloc optique comporte des moyens de retenue ménagés sur ledit masque ou sur ladite armature et aptes à coopérer, lors de la mise en place dudit masque sur ladite armature, avec des moyens complémentaires ménagés sur l'autre de ces éléments lors de la mise en place dudit masque sur ladite armature de sorte à empêcher que ledit fût ne s'écarte de ladite paroi pendant le vissage de ladite vis dans ledit perçage du fût. To this end, it provides an optical signaling and / or lighting unit for a motor vehicle comprising a frame, an optical module mounted on said frame and comprising at least one light device capable of ensuring at least one photometric function, as well as a mask fixed to said frame by means of fixing means and being able to conceal part of said optical module from the view of an observer, said fixing means between the mask and the frame comprising at least one barrel carried by the '' one of these elements and being provided with a hole in which is screwed a screw having previously passed through a corresponding orifice made in a wall carried by the other element; characterized in that said optical unit comprises retaining means provided on said mask or on said frame and capable of cooperating, during the fitting of said mask on said frame, with complementary means provided on the other of these elements during placing said mask on said frame so as to prevent said barrel from moving away from said wall during the screwing of said screw in said piercing of the barrel.
La présence de ces moyens de retenue permet d'assurer la prise de la vis dans le perçage du fût sans que l'opérateur en charge du montage du masque sur l'armature, n'ait à exercer avec l'une de ses mains et concomitamment au vissage un contre-effort sur l'élément portant le fût.  The presence of these retaining means makes it possible to ensure that the screw is taken in the drilling of the barrel without the operator in charge of mounting the mask on the frame, having to exercise with one of his hands and concomitantly with the screwing, a counter-force on the element carrying the barrel.
L'invention simplifie ainsi grandement l'assemblage du masque à l'armature en évitant par ailleurs l'apparition de traces résiduelles de doigt sur ces éléments.  The invention thus greatly simplifies the assembly of the mask to the frame while also avoiding the appearance of residual fingerprints on these elements.

Description détaillée detailed description
On définit sur les figures un repère orthogonal XYZ comprenant trois axes perpendiculaires deux à deux, à savoir :  An XYZ orthogonal coordinate system is defined in the figures, comprising three perpendicular axes two by two, namely:
- un axe X, définissant une direction longitudinale, parallèle à l'axe longitudinal du véhicule, - un axe Y, définissant une direction transversale, horizontale, qui avec l'axe X définit un plan XY horizontal, et - an X axis, defining a longitudinal direction, parallel to the longitudinal axis of the vehicle, - a Y axis, defining a transverse, horizontal direction, which with the X axis defines a horizontal XY plane, and
- un axe Z, définissant une direction verticale, perpendiculaire au plan XY horizontal.  - a Z axis, defining a vertical direction, perpendicular to the horizontal XY plane.
Les figures 1 et 2 représentent une vue en perspective d'un bloc optique arrière de signalisation 1 destiné à être monté sur la structure de caisse d'un véhicule automobile.  Figures 1 and 2 show a perspective view of a rear signaling optical unit 1 intended to be mounted on the body structure of a motor vehicle.
Dans la description qui va suivre et par convention, les termes « inférieur », et « supérieur » seront définis par rapport à la position de montage de ce bloc optique de signalisation 10 sur un tel véhicule automobile.  In the description which follows and by convention, the terms “lower” and “upper” will be defined with respect to the mounting position of this optical signaling unit 10 on such a motor vehicle.
Les termes « externe » et « interne » seront quant à eux utilisés pour définir la position relative d'un élément par référence à l'axe longitudinal du véhicule. L'élément le plus proche de cet axe sera ainsi qualifié d'interne par opposition à l'autre élément plus éloigné de ce même axe qui sera quant à lui qualifié d'externe.  The terms "external" and "internal" will be used to define the relative position of an element with reference to the longitudinal axis of the vehicle. The element closest to this axis will thus be qualified as internal as opposed to the other element more distant from this same axis which will be qualified as external.
Tel qu'illustré par la figure 2, le bloc optique de signalisation 1 comporte une armature 10, un module optique 20 emboîté sur l'armature 10, un masque 30 monté sur l'armature 10 et le module optique 20, une glace extérieure de couverture 40 montée sur le masque 30, ainsi qu'une jupe latérale 50 montée sur l'armature 10.  As illustrated in FIG. 2, the optical signaling unit 1 comprises a frame 10, an optical module 20 fitted onto the frame 10, a mask 30 mounted on the frame 10 and the optical module 20, an external lens of cover 40 mounted on the mask 30, as well as a side skirt 50 mounted on the frame 10.
Destinée à être fixée sur la structure de caisse du véhicule, l'armature 10 est venue avantageusement de moulage d'une seule pièce à partir d'un polymère thermoplastique tel que l'acrylonitrile butadiène styrène (ABS).  Intended to be fixed on the body structure of the vehicle, the frame 10 is advantageously molded in one piece from a thermoplastic polymer such as acrylonitrile butadiene styrene (ABS).
Le module optique 20, dont la conception n'est ici illustrée qu'à titre d'exemple non limitatif, comporte un premier dispositif lumineux 21 assurant la fonction feu de position ou lanterne ainsi qu'un second dispositif lumineux 25 assurant les fonctions feu de recul et feu clignotant indicateur de changement de direction.  The optical module 20, the design of which is here illustrated only by way of nonlimiting example, comprises a first light device 21 ensuring the position light or lantern function as well as a second light device 25 ensuring the light functions reversing and direction indicator flashing light.
Le premier dispositif lumineux 21 comprend trois diodes électroluminescentes (non visibles) implantées sur une plaque à circuits imprimés 22 de type PCB (pour « Printed Circuit Board » en langue anglaise). Ce premier dispositif 22 comporte également un écran transparent ou translucide 23 monté sur une platine support 24 en arrière de ces diodes et destiné à être traversé par les rayons lumineux provenant de ces dernières. The first light device 21 comprises three light-emitting diodes (not visible) installed on a printed circuit board 22 of the PCB type (for “Printed Circuit Board” in English). This first device 22 also includes a transparent or translucent screen 23 mounted on a support plate 24 behind these diodes and intended to be crossed by the light rays coming from the latter.
Le second dispositif lumineux 25 comprend quand à lui cinq diodes électroluminescentes (non visibles) situées sur un second PCB non représenté en regard de cinq guides de lumières 26 de type plat (ou « fiat guide » en langue anglaise) implantés sur la platine support 24 en dessous de l'écran 23 et alignés transversalement les uns par rapport aux autres avec un léger décalage longitudinal .  The second light device 25 comprises five light-emitting diodes (not visible) located on a second PCB not shown opposite five light guides 26 of the flat type (or "fiat guide" in English) located on the support plate 24 below the screen 23 and aligned transversely with respect to each other with a slight longitudinal offset.
Ce module optique 20 est emboîté sur l'armature 10 puis fixé à cette dernière de manière classique par encliquetage et vissage.  This optical module 20 is fitted onto the frame 10 and then fixed to the latter in a conventional manner by snap-fastening and screwing.
Venu avantageusement de moulage d'une seule pièce à partir d'un polymère thermoplastique opaque tel que le polycarbonate (PC), le masque 30 recouvre certaines portions du module optique 20 et de l'armature 10 de sorte à les dissimuler aux yeux d'un observateur situé à l'extérieur du véhicule tout en assurant une partie du style du bloc optique 1.  Advantageously come from molding in one piece from an opaque thermoplastic polymer such as polycarbonate (PC), the mask 30 covers certain portions of the optical module 20 and of the frame 10 so as to conceal them from the eyes of an observer located outside the vehicle while ensuring part of the style of the optical unit 1.
Sa face arrière (celle tournée en direction de la glace de couverture 30) est recouverte avantageusement d'un revêtement métallisé permettant d'assurer une certaine continuité visuelle entre la calandre du véhicule et ce bloc optique 1.  Its rear face (that facing towards the cover glass 30) is advantageously covered with a metallized coating making it possible to ensure a certain visual continuity between the grille of the vehicle and this optical unit 1.
Tel qu'illustré sur les figures 1 et 2, le masque 30 présente une pluralité d'évidements 31, 32 laissant notamment apparaître les trois portions de l'écran 23 situées en regard des diodes du premier dispositif lumineux 22, ainsi que les faces arrière de sortie des rayons lumineux des guides de lumière 26.  As illustrated in FIGS. 1 and 2, the mask 30 has a plurality of recesses 31, 32 revealing in particular the three portions of the screen 23 located opposite the diodes of the first light device 22, as well as the rear faces of light rays leaving the light guides 26.
Les deux extrémités latérales de ce masque 30 sont fixées par vissage sur les extrémités latérales correspondantes de l'armature 10. L'une de ces zones latérales d'assemblage sera décrite plus en détails dans la suite de cette description à l'appui des figures 3 et 4.  The two lateral ends of this mask 30 are fixed by screwing to the corresponding lateral ends of the frame 10. One of these lateral assembly zones will be described in more detail in the following description with the support of the figures 3 and 4.
La glace de couverture transparente 40, réalisée d'une seule pièce par moulage à partir d'un polymère thermoplastique transparent tel que le poly-méthacrylate de méthyle (PMMA) ou le polycarbonate (PC), recouvre le masque 30 en étant fixée sur la bordure périphérique 33 de ce dernier par soudure laser de sorte à assurer une parfaite étanchéité. The transparent cover glass 40, produced in one piece by molding from a transparent thermoplastic polymer such as poly (methyl methacrylate) or polycarbonate (PC), covers the mask 30 by being fixed on the peripheral edge 33 of the latter by laser welding so as to ensure a perfect seal.
Venue également de moulage d'une seule pièce à partir d'un matériau thermoplastique, la jupe latérale 50 est rapportée par encliquetage et vissage sur l'extrémité latérale interne de l'armature 10 afin d'assurer l'interface avec un bord latéral de l'ouverture du compartiment à bagages du véhicule.  Also coming from a single piece molding from a thermoplastic material, the side skirt 50 is attached by snap-fastening and screwing on the internal lateral end of the frame 10 in order to provide the interface with a lateral edge of opening the luggage compartment of the vehicle.
La figure 3 montre la zone latérale externe d'assemblage par vissage entre le masque 30 et l'armature 10.  FIG. 3 shows the external lateral zone of assembly by screwing between the mask 30 and the frame 10.
Comme on peut le constater sur cette figure, le masque 30 comporte, au niveau de son extrémité latérale externe, u n organe de fixation constitué par un fût cylindrique 34 s'étendant selon une direction sensiblement longitudinale.  As can be seen in this figure, the mask 30 comprises, at its external lateral end, a fixing member constituted by a cylindrical barrel 34 extending in a substantially longitudinal direction.
Le fût 34 est pourvu d'un perçage borgne non taraudé (non visible sur les figures) destiné à recevoir une vis auto-taraudeuse 60 ayant préalablement traversé un orifice circulaire d'axe longitudinal 11 ménagé dans une paroi plane sensiblement verticale 12 de l'armature 10 s'étendant à proximité de son bord latéral externe (voir figure 4).  The barrel 34 is provided with a non-tapped blind bore (not visible in the figures) intended to receive a self-tapping screw 60 having previously passed through a circular orifice of longitudinal axis 11 formed in a substantially vertical plane wall 12 of the frame 10 extending near its external lateral edge (see FIG. 4).
Afin de faciliter les opérations de mise en place et de vissage du masque 30 sur l'armature 10, cette dernière comporte des moyens de pré positionnement du fût cylindrique 34 par rapport à l'orifice circulaire 11.  In order to facilitate the operations of fitting and screwing the mask 30 onto the frame 10, the latter comprises means for pre-positioning the cylindrical barrel 34 relative to the circular orifice 11.
Dans la suite de cette description, les termes « amont » et « aval » utilisés pour caractériser la position de certains éléments de l'armature 10 et du masque 30 sont à considérer par rapport au sens de déplacement du fût cylindrique 31 lors du montage de ce masque 30 sur cette armature 10.  In the remainder of this description, the terms “upstream” and “downstream” used to characterize the position of certain elements of the frame 10 and of the mask 30 are to be considered with respect to the direction of movement of the cylindrical barrel 31 during assembly of this mask 30 on this frame 10.
Ces moyens de pré-positionnement comprennent une arche de guidage 13 s'étendant en vis-à-vis et en amont de la paroi plane 12 selon un plan médian parallèle à cette dernière.  These pre-positioning means comprise a guide arch 13 extending opposite and upstream from the planar wall 12 along a median plane parallel to the latter.
Tel qu'illustré par la figure 3, cette arche 13 est prévue pour être traversée, lors de la mise en place du masque 30, par le fût cyl indrique 34 afin de le guider à coulissement jusqu'à ce que sa tranche annulaire vienne reposer contre la paroi plane 12 de l'armature 10 et de sorte que l'axe de son perçage soit aligné latéralement avec l'axe de l'orifice 11. Les deux montants latéraux 13A, 13B de l'arche 13 présentent des bossages respectifs 14 saillant en relief depuis leurs faces intérieures (seul l'un de ces bossages étant visible sur la figure 4). As illustrated in FIG. 3, this arch 13 is intended to be crossed, during the fitting of the mask 30, by the cylindrical barrel 34 in order to guide it to slide until its annular edge comes to rest against the flat wall 12 of the frame 10 and so that the axis of its bore is aligned laterally with the axis of the orifice 11. The two lateral uprights 13A, 13B of the arch 13 have respective bosses 14 projecting in relief from their interior faces (only one of these bosses being visible in FIG. 4).
Ces deux bossages 14, dont les épaisseurs peuvent être ajustées par retrait ou ajout de matière dans le moule d'injection servant à fabriquer l'armature 10, constituent ainsi des organes de mise au point de l'alignement latéral de l'axe du perçage borgne du fût cylindrique 34 avec l'axe de l'orifice circulaire 11.  These two bosses 14, the thicknesses of which can be adjusted by removing or adding material to the injection mold used to manufacture the reinforcement 10, thus constitute bodies for adjusting the lateral alignment of the axis of the bore. blind end of the cylindrical barrel 34 with the axis of the circular orifice 11.
Comme cela est bien visible sur la figure 4, les moyens de pré positionnement comportent également un berceau à profil en arc de cercle As is clearly visible in FIG. 4, the pre-positioning means also include a cradle with a profile in an arc
15 saillant de la face tournée vers l'arche 13 de la paroi 12 sur le pourtour inférieur de l'orifice 11, et prévu pour supporter une portion d'extrémité du fût cylindrique 34 après la mise en place du masque 30 de sorte que son perçage soit aligné verticalement avec l'axe de l'orifice 11. 15 projecting from the face facing the arch 13 of the wall 12 on the lower periphery of the orifice 11, and provided to support an end portion of the cylindrical barrel 34 after the mask 30 has been put in place so that its hole is aligned vertically with the axis of the hole 11.
Le fond du berceau 15 présente également un bossage 16 dont l'épaisseur peut également être ajustée par retrait ou ajout de matière dans le moule d'injection servant à fabriquer l'armature 10, ce bossage The bottom of the cradle 15 also has a boss 16 whose thickness can also be adjusted by removing or adding material to the injection mold used to manufacture the frame 10, this boss
16 constituant un organe de mise au point de l'alignement vertical de l'axe du perçage borgne du fût cylindrique 34 avec l'axe de l'orifice 11. 16 constituting a member for adjusting the vertical alignment of the axis of the blind bore of the cylindrical barrel 34 with the axis of the orifice 11.
La présence de ces moyens de pré-positionnement 13 et 15 permet à l'opérateur en charge du montage du masque 30 sur l'armature 10 de toujours positionner parfaitement, notamment lorsque cette opération est réalisée à l'aveugle, le perçage borgne du fût 31 en regard de l'orifice circulaire 11.  The presence of these pre-positioning means 13 and 15 allows the operator in charge of mounting the mask 30 on the frame 10 to always position perfectly, especially when this operation is carried out blind, the blind drilling of the barrel 31 opposite the circular orifice 11.
Par ailleurs et tel qu'illustré par la figure 3, l'armature 10 comporte une languette élastiquement déformable 16 dont l'extrémité libre 16A est apte à coopérer en butée avec un butoir 35 ménagé sur le masque 30 lors de la mise en place de ce masque sur l'armature 10, de sorte à empêcher que le fût cylindrique 31 ne s'écarte de cette paroi 12 lors du vissage de la vis auto-taraudeuse 60 dans son perçage borgne.  Furthermore and as illustrated in FIG. 3, the frame 10 comprises an elastically deformable tongue 16, the free end 16A of which is capable of cooperating in abutment with a stopper 35 formed on the mask 30 during the fitting of this mask on the frame 10, so as to prevent the cylindrical barrel 31 from moving away from this wall 12 when the self-tapping screw 60 is screwed into its blind bore.
La languette 16 s'étend en amont de l'arche de guidage 13 et de la paroi plane 12, depuis le bord d'une découpe 17 pratiquée dans une semelle horizontale 18, et suivant une direction orientée vers cette paroi 12 et vers le haut. Le butoir 35 est ici constitué par l'extrémité inférieure d'une patte 36 s'étendant selon un plan vertical perpendiculaire à l'axe du fût 34 et sur laquelle la base de dernier prend racine. The tongue 16 extends upstream of the guide arch 13 and the flat wall 12, from the edge of a cutout 17 made in a horizontal flange 18, and in a direction oriented towards this wall 12 and upwards . The stopper 35 is here constituted by the lower end of a tab 36 extending along a vertical plane perpendicular to the axis of the barrel 34 and on which the base of the latter takes root.
Lors de la mise en place du masque 30, l'extrémité inférieure libre du butoir 35 commence par glisser le long de la languette 16 qui se rabat élastiquement et progressivement vers le bas.  When the mask 30 is put in place, the free lower end of the stopper 35 begins by sliding along the tongue 16 which folds elastically and gradually downwards.
Au moment où la tranche annulaire du fût 34 vient au contact de la paroi plane 12, le butoir 35 dépasse la languette qui reprend alors sa position initiale : son extrémité libre se retrouvant alors en regard de ce butoir 35 de sorte à empêcher tour recul du fût 34.  When the annular edge of the barrel 34 comes into contact with the flat wall 12, the stopper 35 exceeds the tongue which then resumes its initial position: its free end then being found opposite this stopper 35 so as to prevent the recoil from was 34.
Selon des variantes de réalisation non représentées, les moyens de pré-positionnement sont conformés différemment.  According to variant embodiments not shown, the pre-positioning means are shaped differently.
Selon d'autres variantes de réalisation non représentés, le fût de fixation est implanté sur l'armature tandis que l'orifice circulaire est ménagé sur une paroi du masque.  According to other alternative embodiments not shown, the fixing barrel is located on the frame while the circular orifice is formed on a wall of the mask.
Selon encore d'autres variantes de réalisation non représentés, la languette élastiquement déformable est également conformée différemment, celle-ci pouvant être par exemple implantée sur le masque tandis que l'élément rigide coopérant avec elle est ménagé sur l'armature.  According to yet other alternative embodiments not shown, the elastically deformable tongue is also shaped differently, the latter being able for example to be installed on the mask while the rigid element cooperating with it is formed on the frame.
