Description

Arrière-plan de l'inventionInvention background

L'invention concerne une touche multifonction pour tableau de bord de véhicule automobile. Le domaine d'application de cette touche est celui des tableaux de commande de chauffage et climatisation, mais aussi des consoles centrales équipées ou non de systèmes de navigation pour véhicules automobiles.The invention relates to a multifunction key for a control panel. on board a motor vehicle. The scope of this key is that of the heating and air conditioning control panels, but also central consoles with or without navigation systems for motor vehicles.

Les tableaux de bord utilisés dans les véhicules automobiles n'utilisent que rarement le concept de touche monobloc multifonction. Un exemple est celui du tableau de bord du véhicule commercialisé par la société française « Peugeot » sous la dénomination « 206 électronique ». Toutefois, le système de touche multifonction utilisé a uniquement deux positions de commande et sa conception paraít relever plus de considérations esthétiques que d'une recherche prioritaire de réduction de volume de l'ensemble des boutons de commande.Dashboards used in motor vehicles rarely use the concept of one-piece multi-function button. A example is that of the dashboard of the vehicle marketed by the French company "Peugeot" under the name "206 electronic". However, the multifunction key system used has only two control positions and its design appear to be more than aesthetic considerations as a priority search for reduction of volume of all control buttons.

Or, en dépit de la sophistication des fonctions qui sont amenées à être intégrées dans les véhicules, qui se traduit par un nombre croissant de touches de fonction, il est souhaitable que le tableau de bord reste le plus compact possible et le plus simple possible à assembler.However, despite the sophistication of the functions that are brought to be integrated into vehicles, which results in a number increasing function keys it is desirable that the dashboard remains as compact as possible and as simple as possible to assemble.

L'utilisation de touches multifonctions paraít être une solution. De telles touches, sont largement utilisées dans les poignées de commande des consoles de jeux. Mais, elles comportent souvent un nombre élevé de pièces, ce qui complique leur assemblage.Using multi-function keys seems to be a solution. Such keys are widely used in the handles of order game consoles. But, they often have a high number of parts, which complicates their assembly.

Description détaillée de modes de réalisation de l'inventionDetailed description of embodiments of the invention

On se réfère maintenant aux dessins, et plus particulièrement, à la figure 1 illustrant une vue de face d'un tableau de bord 1000 de véhicule automobile comportant deux touches multifonctions 100, 200, dont seulement, celle de gauche 100 est entièrement illustrée. Par ailleurs, un écran d'interface 50 ainsi que d'autres touches de commande font aussi partie du tableau de bord 1000.We now refer to the drawings, and more particularly, in Figure 1 illustrating a front view of a dashboard 1000 of motor vehicle comprising two multifunction keys 100, 200, of which only the one on the left 100 is fully illustrated. Through elsewhere, an interface screen 50 as well as other control keys are also part of the 1000 dashboard.

A titre d'exemple, la touche multifonction 100, définit quatre emplacements de commande 25a, 25b, 25c, 25d sur la face externe d'un cabochon 20 correspondant à quatre fonctions particulières. Bien évidemment, le nombre d'emplacements de commande 25a, 25b, 25c, 25d peut être quelconque et toutes sortes de fonctions ainsi que leur modes de régulation peuvent leur être associées.As an example, the multifunction key 100 defines four control locations 25a, 25b, 25c, 25d on the outside of a cabochon 20 corresponding to four specific functions. Well obviously the number of control locations 25a, 25b, 25c, 25d can be any and all kinds of functions as well as their modes of regulation can be associated with them.

En outre, le cabochon 20 permet grâce à son ergonomie intuitive une symbolique sans ambiguïté sur le fonctionnement de la touche multifonction 100. Selon un mode particulier de réalisation, une touche multifonction 100, 200 peut être affectée à une seule fonction principale et les emplacements de commandes 25a, 25b, 25c, 25d peuvent être réservés aux modes de fonctionnement de cette fonction. Par exemple la touche de gauche 100 peut être associée à la climatisation avec un emplacement de commande 25b réservé au mode automatique, un autre 25d réservé à l'annulation (OFF) de la fonction tandis que les deux autres emplacements 25a, 25b sont réservés à l'augmentation ou à la diminution de la valeur de la température. En revanche, la touche de droite 200 peut être associée à la ventilation.In addition, the cabochon 20 allows thanks to its ergonomics intuitive unambiguous symbolism of how the multifunction key 100. According to a particular embodiment, a multifunction key 100, 200 can be assigned to a single function main and control locations 25a, 25b, 25c, 25d can be reserved for the operating modes of this function. For example the left button 100 can be associated with air conditioning with a control space 25b reserved for automatic mode, another 25d reserved for canceling (OFF) the function while the two other locations 25a, 25b are reserved for the increase or the decrease in the temperature value. However, the touch of right 200 can be combined with ventilation.

Il est évident qu'en plus des fonctions de climatisation ou de ventilation, d'autres fonctions peuvent être associées aux touches multifonctions 100, 200 parmi lesquels : lecture de données concernant par exemple un lecteur de cassettes ou de CD, autoradio, navigation, télécommunications, réception-transmission de données, réglage d'intensité etc...It is obvious that in addition to the air conditioning or ventilation, other functions can be associated with the keys multifunction 100, 200 among which: reading of data relating to for example a cassette or CD player, car radio, navigation, telecommunications, reception and transmission of data, regulation intensity etc ...

Selon un autre mode particulier de réalisation, deux emplacements de commande parmi les quatre 25a, 25b, 25c, 25d peuvent être affectées à deux fonctions particulières mutuellement incompatibles, les deux autres emplacements permettant de diminuer ou d'augmenter par impulsion l'intensité ou la valeur de la fonction activée parmi lesdites deux fonctions particulières.According to another particular embodiment, two control locations among the four 25a, 25b, 25c, 25d can be assigned to two mutually incompatible particular functions, the other two locations to decrease or increase by pulse the intensity or the value of the activated function among said two special functions.

Dans tout les cas, l'action des fonctions activées ainsi que leur valeurs ou leur modes de fonctionnement peuvent être affichés sur l'écran d'interface 50 à proximité des touches multifonctions 100, 200.In all cases, the action of the activated functions as well as their values or their operating modes can be displayed on the screen interface 50 near the multifunction keys 100, 200.

La figure 2 est une vue en coupe de la figure 1, montrant la touche multifonction 100 au repos. Cette touche multifonction 100 comporte une façade 10, un cabochon 20, un corps 30 et une carte de circuit électrique 40.Figure 2 is a sectional view of Figure 1, showing the multifunction key 100 at rest. This multifunction key 100 has a front 10, a cap 20, a body 30 and a card electrical circuit 40.

La façade 10 définit une ouverture circulaire 11 dont le rebord est sensiblement cylindrique 12 sur sa partie supérieure et sphérique concave 13 sur sa partie inférieure. Le cabochon 20 a une forme similaire à celle de l'ouverture 11 de la façade 10, et présente une jupe 21 qui s'engage dans le pourtour de l'ouverture 11. Sur sa partie extérieure, la jupe 21 du cabochon 20 est cylindrique 22 sur une partie supérieure, sphérique convexe 23 sur une autre partie et se termine par un rebord inférieur transversal 26.The facade 10 defines a circular opening 11 whose rim is substantially cylindrical 12 on its upper and spherical part concave 13 on its lower part. The cabochon 20 has a similar shape to that of the opening 11 of the facade 10, and has a skirt 21 which engages around the opening 11. On its outer part, the skirt 21 of cabochon 20 is cylindrical 22 on an upper part, convex spherical 23 on another part and ends in a rim lower transverse 26.

Le corps 30 comprend une tête 31 avec une face de même forme que le cabochon 20 et une partie centrale formant pied 32 comportant à sa base une calotte sphérique 33. En outre, le corps 30 est en matériau transparent ou translucide formant un prisme optique. Le corps 30 est solidairement assemblé avec le cabochon 20 par engagement et coincement de la tête 31 dans la partie interne du cabochon 20. Il peut être engagé dans le cabochon 20, soit librement, soit par un détrompage particulier. Des godrons ou autres reliefs ou parties en saillie, non représentés sur les dessins, situés sur le bord de la tête 31 vont permettre un assemblage solidaire entre le corps 30 et le cabochon 20.The body 30 includes a head 31 with a face of the same form that the cabochon 20 and a central part forming a foot 32 comprising at its base a spherical cap 33. In addition, the body 30 is made of transparent or translucent material forming an optical prism. The body 30 is integrally assembled with the cap 20 by engagement and jamming of the head 31 in the internal part of the cabochon 20. It can be engaged in cabochon 20, either freely or by a particular keying. Gadroons or other reliefs or parts in projection, not shown in the drawings, located on the edge of the head 31 will allow an integral assembly between the body 30 and the cabochon 20.

Il est à noter que, l'ensemble cabochon-corps peut être composé d'une seule pièce transparente ou translucide dans sa partie corps ou prisme 30 et opaque dans sa partie cabochon 20. Cette pièce entièrement transparente ou translucide au départ peut être peinte en blanc et ensuite en noir sur la partie qui correspond au cabochon 20. L'ensemble cabochon-corps peut aussi être réalisé par une double injection de deux matières différentes correspondant aux deux différentes parties. It should be noted that the cabochon-body assembly can be composed of a single transparent or translucent part in its part body or prism 30 and opaque in its cabochon part 20. This piece completely transparent or translucent at the start can be painted in white and then black on the part which corresponds to the cabochon 20. The cabochon-body assembly can also be produced by a double injection of two different materials corresponding to the two different parts.

Qu'il soit en une ou deux pièces, l'ensemble cabochon-corps s'engage dans l'ouverture de la façade 10. La partie sphérique convexe 23 de la jupe 21 du cabochon 20 s'adapte en s'articulant dans la partie sphérique concave 13 de la façade 10 formant ainsi une portée sphérique. Comme le montre plus particulièrement la figure 3, le positionnement correct de l'ensemble cabochon-corps est assuré par des moyens de détrompage aménagés par des reliefs complémentaires 24,14 formés sur la jupe 21 du cabochon 20 et sur le rebord de la façade 10. Ces mêmes reliefs complémentaires 24,14 immobilisent toute rotation de l'ensemble cabochon-corps autour d'un axe perpendiculaire à la façade 10.Whether in one or two pieces, the cabochon-body assembly engages in the opening of the facade 10. The convex spherical part 23 of the skirt 21 of the cabochon 20 adapts by being articulated in the part concave spherical 13 of the facade 10 thus forming a spherical bearing. As shown more particularly in Figure 3, the positioning correct of the cabochon-body assembly is ensured by means of coding provided by complementary reliefs 24.14 formed on the skirt 21 of the cabochon 20 and on the edge of the facade 10. These same additional reliefs 24.14 immobilize any rotation of the assembly cabochon-body around an axis perpendicular to the facade 10.

Dans l'exemple de la figure 3, les reliefs complémentaires 24, 14 sont constitués des rainures 24 formées sur la jupe 21 qui s'engagent sur des nervures 14 correspondantes sur le rebord de la façade 10 (voir aussi figure 5). Inversement, les nervures peuvent appartenir au cabochon 20 et les rainures à la façade 10.In the example of FIG. 3, the complementary reliefs 24, 14 consist of grooves 24 formed on the skirt 21 which engage on corresponding ribs 14 on the edge of the facade 10 (see also figure 5). Conversely, the ribs can belong to the cabochon 20 and the grooves on the facade 10.

Toutefois, il est à remarquer que l'ensemble cabochon-corps ainsi que l'ouverture de la façade peuvent avoir toute forme particulière, par exemple la forme d'un trèfle à quatre feuilles, qui s'oppose à toute rotation de l'ensemble cabochon-corps autour d'un axe perpendiculaire à la façade.However, it should be noted that the cabochon-body assembly as well as the opening of the facade can have any particular shape, for example the shape of a four-leaf clover, which opposes any rotation of the cabochon-body assembly about an axis perpendicular to the facade.

La carte de circuit électrique 40 est fixée derrière la façade 10 et maintient en position l'ensemble des éléments de la touche multifonction 100. La carte électrique 40 comporte une pluralité de boutons poussoirs ou cloques 41 protégés par une membrane silicone 43 et correspondant à la pluralité d'emplacements de commande 25a, 25b, 25c, 25d. La membrane silicone 43 produit une bonne sensation tactile lors d'un appui sur un emplacement de commande 25a, 25b, 25c, 25d. L'ensemble cabochon-corps est maintenu plaqué au centre de la partie sphérique 13 de la façade 10 par les cloques 41 associés à la membrane 43, en réponse à une légère contrainte exercé sur eux par l'intermédiaire du rebord inférieur 26 de la jupe 21 du cabochon 20.The electrical circuit board 40 is fixed behind the front panel 10 and keeps all the elements of the key in position multifunction 100. The electric card 40 comprises a plurality of push buttons or blisters 41 protected by a silicone membrane 43 and corresponding to the plurality of control locations 25a, 25b, 25c, 25d. The silicone membrane 43 produces a good tactile sensation when pressing on a control location 25a, 25b, 25c, 25d. The cabochon-body assembly is kept pressed in the center of the part spherical 13 of the facade 10 by the blisters 41 associated with the membrane 43, in response to a slight constraint exerted on them through from the lower edge 26 of the skirt 21 of the cabochon 20.

La calotte sphérique 33 à la base du corps 30 présente un jeu minimum avec la carte du circuit électrique 40 laissant l'ensemble cabochon-corps flottant dans la façade 10 et guidé par l'appui de la partie sphérique convexe 23 du cabochon 20 contre la partie sphérique concave 13 de la façade 10. The spherical cap 33 at the base of the body 30 has a play minimum with the electrical circuit board 40 leaving the assembly cabochon-body floating in the facade 10 and guided by the support of the part convex spherical 23 of the cap 20 against the concave spherical part 13 of the facade 10.

En outre, la carte de circuit électrique 40, comporte un moyen de rétro-éclairage constitué par exemple de deux diodes électroluminescentes 42, éclairant des symboles associés aux fonctions particulières et portés par la face externe du cabochon 20.In addition, the electric circuit card 40, comprises a means backlight consisting for example of two diodes electroluminescent 42, illuminating symbols associated with the functions particular and carried by the outer face of the cap 20.

La lumière des diodes 42 est diffusée d'une manière homogène par le corps 30 qui se comporte dans ce cas, comme un prisme optique. Par contre, elle n'est pas diffusée à travers des jeux périphériques. En effet, l'adaptation de la partie sphérique convexe 23 de la jupe 21 du cabochon 20 dans la partie sphérique concave 13 de la façade 10, forme une barrière périphérique vis-à-vis de la lumière de rétro-éclairage 42.The light from the diodes 42 is diffused in a homogeneous manner by the body 30 which behaves in this case, like an optical prism. However, it is not broadcast through peripheral games. In effect, the adaptation of the convex spherical part 23 of the skirt 21 of the cabochon 20 in the concave spherical part 13 of the facade 10, shape a peripheral barrier against the backlight light 42.

On se réfère maintenant aux figures 4 et 5, montrant la touche multifonction 100 en action. En fonctionnement, la calotte sphérique 33 du corps 30 repose sur la carte électrique 40 pour former un point pivot définissant une intersection d'axes coplanaires au plan de la carte électrique 40 autour desquels l'ensemble cabochon-corps présente une pluralité de mouvement de pivotement en s'articulant sur la portée sphérique formée entre le cabochon 20 et la façade 10.We now refer to Figures 4 and 5, showing the key multifunction 100 in action. In operation, the spherical cap 33 of the body 30 rests on the electric card 40 to form a pivot point defining an intersection of coplanar axes on the map plane electric 40 around which the cabochon-body assembly has a plurality of pivoting movements, articulated on the span spherical formed between the cabochon 20 and the facade 10.

En plus d'une fonction d'articulation et d'une barrière contre des fuites de lumière, la portée sphérique formée par les portions sphériques convexe 23 et concave 13 permet d'éliminer le jeu périphérique ainsi que le bruit d'articulation. En effet, des godrons fins, non représentés sur les dessins, formés sur la portion sphérique convexe 23 ou concave 13 vont limiter la surface de contact ou d'emprise éliminant ainsi les frottements et les jeux ou tout au moins les réduisant à des valeurs infimes.In addition to an articulation function and a barrier against light leaks, the spherical bearing formed by the spherical portions convex 23 and concave 13 eliminates peripheral play as well as articulation noise. Indeed, fine gadroons, not shown on the drawings, formed on the convex 23 or concave 13 spherical portion go limit the contact or grip surface thus eliminating friction and games or at least reducing them to minute values.

La pluralité de mouvement de pivotement actionnent la pluralité de cloques 41 de la carte électrique 40, par l'intermédiaire du rebord inférieur 26 de la jupe 21 du cabochon 20. Chaque mouvement de pivotement présente une amplitude limitée par la jupe 21 du cabochon 20 coopérant avec le rebord de la façade 10. Dans l'exemple de la figure 4, l'amplitude de pivotement est d'environ plus ou moins 4°.The plurality of pivoting movements operate the plurality blisters 41 of the electric card 40, via the rim lower 26 of the skirt 21 of the cabochon 20. Each movement of pivoting has an amplitude limited by the skirt 21 of the cabochon 20 cooperating with the edge of the facade 10. In the example of FIG. 4, the pivoting amplitude is approximately plus or minus 4 °.

La figure 6, illustre le maintien en position de l'ensemble des éléments de la touche multifonction 100 lors de la fixation de la carte électrique 40 derrière la façade 10. La carte électrique 40 peut être fixée, comme dans l'exemple de la figure 6, par l'intermédiaire d'un capot 60 avec des moyens de fixation 61. FIG. 6 illustrates the maintenance in position of all of the elements of the multifunction key 100 when attaching the card electric 40 behind the facade 10. The electric card 40 can be fixed, as in the example of FIG. 6, by means of a cover 60 with fixing means 61.

La figure 6, montre aussi les deux diodes électroluminescentes 42 qui illuminent des formes spécifiques en relief formées sur la face externe du cabochon 20 après diffusion de la lumière par le corps 30 transparent ou translucide.Figure 6 also shows the two light emitting diodes 42 which illuminate specific relief shapes formed on the face outer of the lens 20 after light has been diffused by the body 30 transparent or translucent.

Les exemples décrits précédemment pourraient être transposés à une touche multifonction comportant un nombre total d'emplacements de commande différent de quatre en réadaptant l'ergonomie des formes spécifiques sur la face du cabochon et en choisissant le nombre approprié de cloques.The examples described above could be transposed to a multifunction key with a total number of locations of command different from four by readjusting the ergonomics of the forms specific on the face of the cabochon and choosing the appropriate number blisters.
