Description

1 La présente invention concerne les cornbinés de tableau de bord deThe present invention relates to the dashboard cornbines of

véhicule automobile du type comportant au moins un indicateur à aiguille. L'indicateur comporte alors généralement un cadran centré sur l'axe de l'aiguille et portant sur sa périphérie des indications, de vitesse ou autre, en regard desquelles l'aiguille est positionnée en temps réel par un moteur pas à pas pour pointer l'indication pertinente. Comme l'indicateur occupe une surface importante, la partie centrale de cette surface est mise à profit pour supporter un second indicateur, par exemple un 10 indicateur LCD (liquid crystal display). Tous ces éléments, cadran, aiguille, LCD, ont besoin d'être éclairés de façon conforme à la technologie de chacun d'eux. Ordinairement, l'éclairage est assuré par des LEDs (light emitting diodes) disposées sur une carte de circuit imprimé située en arrière du combiné, en regard des 15 éléments à éclairer, ou des extrémités amont de guides de lumière plus ou moins compliqués pour conduire la lumière émise par les LEDs depuis la carte de circuit imprimé jusque chacun de ces éléments. L'ensemble du combiné est de ce fait techniquement relativement complexe et nécessite en plus un montage coûteux. 20 La demanderesse a cherché à remédier à cet état de fait et c'est ainsi qu'elle propose son invention. Ainsi, la présente invention concerne un combiné de tableau de bord comprenant un premier indicateur à aiguille rotative, avec une partie centrale comportant un second indicateur et une partie périphérique comprenant un cadran du 25 premier indicateur, le combiné étant caractérisé par le fait que l'aiguille, le cadran du premier indicateur et le second indicateur sont éclairés par une seule et même source lumineuse située en arrière de la partie centrale du premier indicateur. De préférence, l'aiguille du premier indicateur est formée sur un disque rotatif et le disque est agencé pour réfléchir et conduire la lumière depuis sa partie 30 centrale jusqu'à sa périphérie de façon à éclairer le cadran avec une intensité indépendante de la position angulaire du disque. 2905094 2 On remarquera que le disque étant éclairé dans sa globalité, l'aiguille se trouve être également éclairée. Avantageusement, l'aiguille étant sérigraphiée sur le côté arrière du disque, il est possible de lui donner toute forme souhaitable sans aucune difficulté. 5 De préférence encore, le second indicateur reçoit l'éclairage de la source lumineuse à travers l'axe central du disque. Avantageusement, le second indicateur est un indicateur LCD éclairé sans autre conduit de lumière que ledit conduit central de lumière ci-dessus et qui est suspendu devant la partie centrale du disque par une console en forme de potence qui le laisse libre en rotation. Avantageusement toujours, le combiné comporte une carte de circuit imprimé, la source lumineuse est constituée d'une série de diodes électroluminescentes entourant l'axe du moteur du premier indicateur, les diodes étant implantées sur la carte de circuit imprimé du combiné.  motor vehicle of the type comprising at least one pointer indicator. The indicator then generally comprises a dial centered on the axis of the needle and bearing on its periphery indications, speed or other, with respect to which the needle is positioned in real time by a stepper motor to point the relevant indication. Since the indicator occupies a large area, the central part of this surface is used to support a second indicator, for example an LCD (liquid crystal display) indicator. All these elements, dial, needle, LCD, need to be illuminated in a manner consistent with the technology of each one. Ordinarily, the lighting is provided by LEDs (light emitting diodes) arranged on a printed circuit board located behind the handset, facing the 15 elements to be illuminated, or upstream ends of light guides more or less complicated to drive. the light emitted by the LEDs from the circuit board to each of these elements. The entire handset is therefore technically relatively complex and also requires expensive mounting. 20 The plaintiff sought to remedy this state of affairs and thus it proposes its invention. Thus, the present invention relates to a dashboard handset comprising a first rotary pointer indicator, with a central portion having a second indicator and a peripheral portion including a dial of the first indicator, the handset being characterized by the fact that the needle, the dial of the first indicator and the second indicator are illuminated by a single light source located behind the central portion of the first indicator. Preferably, the first indicator needle is formed on a rotating disc and the disc is arranged to reflect and conduct light from its central portion to its periphery so as to illuminate the dial with an intensity independent of the angular position. of the disc. 2905094 2 Note that the disc being illuminated in its entirety, the needle is also illuminated. Advantageously, the needle being serigraphed on the rear side of the disc, it is possible to give it any desirable shape without any difficulty. More preferably, the second indicator receives illumination from the light source through the central axis of the disk. Advantageously, the second indicator is an LCD indicator illuminated with no other light conduit than said central light channel above and which is suspended in front of the central portion of the disk by a bracket-shaped bracket which leaves it free to rotate. Advantageously still, the handset comprises a printed circuit board, the light source consists of a series of light emitting diodes surrounding the axis of the motor of the first indicator, the diodes being located on the printed circuit board of the handset.

Le montage est alors très simple. D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description ci-après du combiné selon l'invention, faite en référence au dessin annexé sur lequel : la figure 1 est une vue avant du combiné selon l'invention et la figure 2 représente une vue en coupe axiale du combiné de la figure 1 selon la ligne II-II. En référence à la figure 1, le combiné 1 d'un véhicule automobile comporte ici deux premiers indicateurs 2, à aiguille, chacun recouvert en partie d'une console 3 en forme de potence prenant appui sur la partie inférieure du combiné et à laquelle est suspendu un deuxième indicateur 4, ici un indicateur LCD, au droit de la partie centrale du premier indicateur 2. La console 3 est ici rendue plus rigide grâce à un bras 9 en matière plastique transparente permettant de supporter l'extrémité de la potence située en partie centrale du premier indicateur 2 en prenant appui sur sa partie supérieure.  The assembly is very simple. Other features and advantages of the present invention will appear more clearly on reading the following description of the handset according to the invention, with reference to the appended drawing in which: FIG. 1 is a front view of the handset according to FIG. invention and Figure 2 shows an axial sectional view of the handset of Figure 1 along the line II-II. Referring to Figure 1, the handset 1 of a motor vehicle here comprises two first indicators 2, needle, each partially covered with a bracket 3 in the form of a stem bearing on the lower part of the handset and to which is suspended a second indicator 4, here an LCD indicator, to the right of the central portion of the first indicator 2. The console 3 is here made more rigid thanks to an arm 9 made of transparent plastic material to support the end of the bracket located in central part of the first indicator 2 by resting on its upper part.

Chaque indicateur à aiguille 2 comporte une aiguille rotative 6 pointant sur un cadran 5, réalisé sur un support rigide 34 en polycarbonate sur lequel sont sérigraphiées des indications 7, essentiellement une échelle de graduations et certaines grandeurs 2905094 3 repères de paramètres de conduite du véhicule,, par exemple des valeurs de vitesse de vingt en vingt kilomètres par heure. L'aiguille 6 est ici de réalisation particulière et est également sérigraphiée sur un disque rotatif 22 en polycarbonate transparent recouvrant le cadran 5 et c'est le 5 disque 22 qui est entraîné en rotation par le moteur 14 du premier indicateur 2 dont il sera question plus en détail par la suite. Le disque 22 est positionné en rotation de sorte que l'aiguille sérigraphiée 6 se trouve constamment maintenue en regard des graduations pertinentes 7, en temps réel. La structure et le fonctionnement du combiné 1 vont maintenant être décrits plus en 10 détail, en référence à la figure 2. Sur la figure 2, on peut mieux voir le boîtier 16 du combiné 1 supportant son rehaut 11 fermé par une vitre antérieure 12 et sa carte de circuit imprimé 13. Les formes de potence de la console 3 et du bras 9 laissent le disque 22 libre en rotation et permettent l'alimentation électrique 26 du deuxième indicateur 4 à partir de la carte 15 de circuit imprimé 13. Le moteur 14 du premier indicateur 2, un moteur pas à pas ordinaire, est implanté à l'arrière de la carte de circuit imprimé 13 et l'axe 15 du moteur 14 la traverse librement et est solidaire du disque 22 situé à l'avant de sorte que ce dernier peut tourner librement en rotation, entraîné par le moteur 14.  Each needle pointer 2 comprises a rotating needle 6 pointing to a dial 5, made on a rigid support 34 made of polycarbonate on which are screen printed indications 7, essentially a scale of graduations and some sizes 2905094 3 vehicle driving parameter markings, for example speed values of twenty in twenty kilometers per hour. The needle 6 is here of particular embodiment and is also screen printed on a rotating disk 22 made of transparent polycarbonate covering the dial 5 and it is the disk 22 which is rotated by the motor 14 of the first indicator 2 which will be discussed in more detail later. The disk 22 is positioned in rotation so that the screen-printed needle 6 is constantly held facing the relevant graduations 7, in real time. The structure and operation of the handset 1 will now be described in more detail with reference to FIG. 2. In FIG. 2, the case 16 of the handset 1 supporting its flange 11 closed by an anterior window 12 can be better seen. 13. The jib forms of the console 3 and the arm 9 leave the disc 22 free to rotate and allow the power supply 26 of the second indicator 4 from the printed circuit board 13. The motor 14 of the first indicator 2, an ordinary stepper motor, is located at the rear of the printed circuit board 13 and the axis 15 of the motor 14 passes freely and is integral with the disc 22 located at the front so that the latter can rotate freely in rotation, driven by the motor 14.

20 De plus, l'axe 15 et le disque 22 sont solidaires entre eux par l'intermédiaire d'un axe cylindrique 23 solidaire du disque 22, de même axe de rotation que l'axe 15, et du même matériau polycarbonate transparent, ou autre, servant de guide de lumière comme il est précisé ci-après. Sur la face tournée vers l'avant de la carte de circuit imprimé 13 et autour de l'axe 25 15, sont implantée des LEDs (ici au nombre de six) servant de source de lumière unique 21 éclairant la face arrière de la partie centrale du disque 22, tant l'axe 23 qu'autour de cet axe. Notons d'ores et déjà que cette source éclaire le disque 22, l'aiguille 6, le cadran 5 et l'indicateur LCD 4. C'est le support rigide 34 qui forme boîte à lumière. Le disque 22 est un disque indicateur lumineux.In addition, the axis 15 and the disk 22 are integral with each other via a cylindrical axis 23 secured to the disk 22, of the same axis of rotation as the axis 15, and of the same transparent polycarbonate material, or other, serving as a light guide as specified below. On the face facing the front of the printed circuit board 13 and around the axis 25 15, LEDs are installed (here six in number) serving as a single light source illuminating the rear face of the central portion. disc 22, both the axis 23 around this axis. Note already that this source illuminates the disc 22, the needle 6, the dial 5 and the LCD indicator 4. It is the rigid support 34 which forms a light box. The disc 22 is a luminous indicator disc.

30 La face antérieure du disque 22 est façonnée en sa partie centrale pour présenter un évidement conique 25 d'angle au sommet de 45 et de même axe que l'axe 15 et en périphérie selon une portion tronconique 30 très évasée entre le côté arrière 31 et le côté avant 32 du disque 22 s'étendant parallèlement à la carte 13 ; une zone striée de 2905094 4 stries circulaires formant une couronne 8 adjacente au côté avant 32 du disque 22. Le cône 25 permet de renvoyer, ou réfléchir, la lumière de la source 21 à 90 vers la portion tronconique 30 et la couronne striée 8 qui la renvoient vers sa périphérie 33 et vers le cadran 5. Ainsi on éclaire le cadran 5 avec une intensité indépendante de la 5 position angulaire du disque 22. C'est sur le côté arrière 31 de la portion tronconique 30 du disque 22, sur sa périphérie, près du bord libre circulaire 33, qu'est sérigraphiée l'aiguille 6. La partie centrale du flux issue de la source 21 traverse l'axe central 23 et éclaire la face arrière du LCD 4 avec une intensité indépendante de la position angulaire du 10 disque 22. On peut prévoir un filtre intermédiaire 10 agencé pour homogénéiser l'éclairage et adapter le flux lumineux issu de la source 21 en fonction du LCD utilisé ou pour obtenir une couleur particulière. Le combiné 1 est ainsi agencé de sorte que l'aiguille 6, le cadran 5 du premier 15 indicateur 2 et le second indicateur 4 sont éclairés par une seule et même source lumineuse 21 située à l'arrière de la partie centrale du premier indicateur 2 ainsi que du second indicateur 4. L'échelle et les chiffres du cadran 5 sont de préférence obtenus à l'aide d'une encre fluorescente afin de mieux capter la lumière. On soulignera qu'ils sont sérigraphiés 20 directement sur le support 34, ce qui permet d'économiser une feuille de polycarbonate. L'aiguille 6 étant sérigraphiée à l'arrière du disque transparent 22, beaucoup de formes sont ainsi possibles. On notera aussi que la lumière injectée dans le disque 22 permet l'éclairage nocturne 25 des indicateurs. Les intérêts de l'invention sont nombreux et on citera la simplicité de réalisation du combiné, son faible coût, sa faible profondeur, notamment Les LEDs 21 peuvent être implantés selon une couronne entourant l'axe 15 du moteur 14. 30The front face of the disk 22 is shaped at its central portion to have a conical aperture recess 25 at the apex of 45 and having the same axis as the axis 15 and at the periphery in a very flared frustoconical portion 30 between the rear side 31. and the front side 32 of the disk 22 extending parallel to the card 13; a ridged zone of 2905094 4 circular striations forming a ring 8 adjacent to the front side 32 of the disc 22. The cone 25 makes it possible to return or reflect the light of the source 21 to 90 towards the frustoconical portion 30 and the ridged crown 8 which it sends back to its periphery 33 and to the dial 5. Thus, the dial 5 is illuminated with an intensity independent of the angular position of the disk 22. It is on the rear side 31 of the frustoconical portion 30 of the disk 22, on its periphery, near the free circular edge 33, which is screen printed the needle 6. The central portion of the stream from the source 21 through the central axis 23 and illuminates the rear face of the LCD 4 with an intensity independent of the angular position Disc 22 may be provided with an intermediate filter 10 arranged to homogenize the illumination and adapt the luminous flux from the source 21 according to the LCD used or to obtain a particular color. The handset 1 is thus arranged so that the hand 6, the dial 5 of the first indicator 2 and the second indicator 4 are illuminated by a single light source 21 located at the rear of the central portion of the first indicator 2 as well as the second indicator 4. The scale and numbers of the dial 5 are preferably obtained using a fluorescent ink to better capture the light. Note that they are screen printed directly on the support 34, which saves a polycarbonate sheet. The needle 6 being serigraphed on the back of the transparent disk 22, many shapes are thus possible. It will also be noted that the light injected into the disk 22 allows the night illumination 25 of the indicators. The interests of the invention are numerous and mention the simplicity of realization of the handset, its low cost, its shallow depth, in particular LEDs 21 can be implanted according to a ring surrounding the axis 15 of the engine 14. 30
