Les systèmes radio permettent des réglages pour des recherches rapides en fonction du programme diffusé ou selon que la station diffuse ou non des messages sur l'état du trafic de la région parcourue.Radio systems allow settings for quick searches based on the program being broadcast or whether or not the station is broadcasting traffic status messages for the region being traveled.
Pour les systèmes de climatisation, on a vu récemment apparaître la gestion des réglages des paramètres de la climatisation par zones.For air conditioning systems, we have recently seen the management of the settings of the air conditioning parameters by zones.
Tous ces systèmes nécessitent des moyens de commande adaptés qui soient ergonomiques et faciles d'utilisation.All these systems require adapted control means that are ergonomic and easy to use.
Pour faciliter les commandes dans un véhicule automobile et diminuer le nombre de commandes individuelles, des commandes multifonctions associées à un écran d'affichage ont fait leur apparition dans le domaine automobile.To facilitate orders in a motor vehicle and reduce the number of individual orders, multifunctional controls associated with a display screen have appeared in the automotive field.
Ces commandes connues ont par exemple la forme d'une manette de commande ou joystick permettant de naviguer dans un menu affiché à l'écran. La sélection d'une fonction choisie se réalise par exemple par un appui sur l'élément de préhension de la commande.These known commands have for example the form of a joystick or joystick for navigating a menu displayed on the screen. The selection of a chosen function is achieved for example by pressing on the gripping element of the command.
De plus, on a doté ce joystick d'un organe rotatif de commande qui permet par exemple d'augmenter ou de diminuer le volume d'un système audio lorsque cette fonction de réglage du volume a été choisie.In addition, this joystick has been equipped with a rotary control device which makes it possible, for example, to increase or decrease the volume of an audio system when this volume adjustment function has been chosen.
Ainsi, avec une seule commande multifonctions, on arrive à commander une multitude de systèmes électroniques et de fonctions dans un véhicule automobile. Du fait du nombre de fonctions pouvant être commandées, ce joystick devient une interface privilégiée du conducteur.Thus, with a single multifunction control, one manages to control a multitude of electronic systems and functions in a motor vehicle. Because of the number of functions that can be controlled, this joystick becomes a privileged interface of the driver.
II en résulte, que l'extrémité libre de ce joystick devient un emplacement aussi important pour la marque du véhicule que par exemple le volant.As a result, the free end of this joystick becomes a location as important for the make of the vehicle as for example the steering wheel.
Or, sur les dispositifs de commande multifonction connus dans l'état de la technique, en apposant par exemple un logo sur cette extrémité, le logo tourne, ce qui n'est pas souhaitable.However, on the multifunction control devices known in the state of the art, for example by affixing a logo on this end, the logo rotates, which is not desirable.
La présente invention vise à proposer une solution par rapport à ce problème.The present invention aims to propose a solution with respect to this problem.
De plus, les joysticks connus sont généralement d'une conception, en particulier électrique ou électronique, complexe.In addition, the known joysticks are generally of a design, in particular electrical or electronic, complex.
Un autre objet de la présente invention vise à proposer un dispositif, dont notamment la partie électrique / électronique soit simplifiée.Another object of the present invention is to provide a device, including the electrical / electronic part is simplified.
Indépendamment de ce problème, selon encore un autre objectif de la présente invention, on vise à proposer un dispositif de commande multifonctions dont la manette de commande puisse être éclairée de façon fiable.Independently of this problem, according to yet another object of the present invention, it is intended to provide a multifunctional control device whose joystick can be reliably illuminated.
A cet effet, l'invention a pour objet un dispositif de commande électrique comprenantFor this purpose, the subject of the invention is an electrical control device comprising
• une manette de commande déplaçable selon un mouvement de pivotement dans un plan perpendiculaire à la manette en position de repos, et déplaçable en translation selon une direction parallèle à la manette en position de repos, • un organe rotatif de commande déplaçable selon un mouvement de rotation et selon un mouvement de pivotement dans un plan perpendiculaire à la manette en position de repos, etA control lever movable according to a pivoting movement in a plane perpendicular to the handle in the rest position, and movable in translation in a direction parallel to the handle in the rest position, A rotary control member displaceable according to a rotational movement and in a pivoting movement in a plane perpendicular to the handle in the rest position, and
• un circuit électrique pour transformer les divers mouvements de la manette et de l'organe rotatif en signaux de commande, caractérisé en ce qu'il comporte un socle de manette mobile sur une course prédéfinie selon une direction parallèle à la manette en position de repos et maintenant la manette de commande fixe en rotation et en ce qu'il comporte une liaison à cardan supportant l'organe rotatif de commande de manière à relier celui-ci en pivotement à la manette de commande.An electrical circuit for transforming the various movements of the handle and the rotary member into control signals, characterized in that it comprises a joystick base movable on a predefined stroke in a direction parallel to the handle in the rest position and now the control lever fixed in rotation and in that it comprises a cardan connection supporting the rotary control member so as to connect it pivotally to the control lever.
D'autres avantages et caractéristiques apparaîtront à la lecture de la description de l'invention, ainsi que sur les figures annexées sur lesquelles : la figure 1 est une vue en perspective d'un dispositif selon l'invention à l'état assemblé, - la figure 2 est une première vue en éclaté du dispositif selon l'invention, la figure 3 est une seconde vue en éclaté du dispositif selon l'invention, la figure 4 est une vue de dessus d'un dispositif selon l'invention, et la figure 5 est une vue en coupe selon A-A de la figure 4.Other advantages and characteristics will appear on reading the description of the invention, as well as on the appended figures in which: FIG. 1 is a perspective view of a device according to the invention in the assembled state, FIG. 2 is a first exploded view of the device according to the invention, FIG. 3 is a second exploded view of the device according to the invention, FIG. 4 is a view from above of a device according to the invention, and Figure 5 is a sectional view along AA of Figure 4.
Le dispositif de commande électrique selon l'invention est représenté selon différentes vues sur toutes les figures annexées. Sur toutes les figures, les mêmes éléments portent les mêmes références.The electrical control device according to the invention is shown according to different views in all the accompanying figures. In all the figures, the same elements bear the same references.
La figure 1 est une vue en perspective d'un dispositif de commande électrique 1 selon l'invention à l'état assemblé.Figure 1 is a perspective view of an electrical control device 1 according to the invention in the assembled state.
Ce dispositif est monté dans un boîtier 3 composé d'un fond 5 et d'un couvercle 7 assemblés à l'aide de moyens de vissage 9 (voir figures 2 et 5).This device is mounted in a housing 3 composed of a bottom 5 and a cover 7 assembled by means of screwing means 9 (see FIGS. 2 and 5).
Il comprend une manette de commande 11 déplaçable selon un mouvement de pivotement dans un plan perpendiculaire à la manette en position de repos.It comprises a control lever 11 movable in a pivoting movement in a plane perpendicular to the handle in the rest position.
Sur les figures 1 et 5, la manette 11 est montrée en position de repos, c'est-à-dire que la manette 11 est essentiellement perpendiculaire au plan défini par le fond 5. Le mouvement de pivotement de la manette 11 est représenté sur la figure 1 par des flèches TXl, TX2, TYl, TY2. On constate donc qu'il y a une première direction de pivotement selon un axe X et une seconde direction de pivotement selon un axe Y qui est orthogonale à la première direction et est située dans le même plan que cette première direction.In Figures 1 and 5, the handle 11 is shown in the rest position, that is to say that the lever 11 is substantially perpendicular to the plane defined by the bottom 5. The pivoting movement of the handle 11 is shown on FIG. 1 with arrows TX1, TX2, TY1, TY2. So we see that there is a first direction of pivoting along an axis X and a second direction of rotation along an axis Y which is orthogonal to the first direction and is located in the same plane as this first direction.
Dans le cadre d'un système multifonctions avec écran d'affichage, ces mouvements de pivotement peuvent par exemple être utilisés pour commander des menus déroulants.In the context of a multifunction system with display screen, these pivoting movements can for example be used to control drop-down menus.
De plus, la manette 11 est également déplaçable en translation selon une direction parallèle à la manette en position de repos. Cette direction est indiquée sur la figure 1 par la flèche TZl.In addition, the handle 11 is also movable in translation in a direction parallel to the handle in the rest position. This direction is indicated in FIG. 1 by the arrow TZ1.
Généralement, ce mouvement est donc pour un utilisateur un appui et est par exemple utilisé pour valider le choix d'une fonction sélectionnée auparavant.Generally, this movement is therefore for a user a support and is for example used to validate the choice of a previously selected function.
Le dispositif de commande électrique selon l'invention comprend en outre un organe rotatif de commande 13 déplaçable selon un mouvement de rotation autour de son axe.The electrical control device according to the invention further comprises a rotary control member 13 movable in a rotational movement about its axis.
De plus, l'organe 13 peut également être déplacé en pivotement selon les mêmes mouvements que la manette 11, c'est-à-dire des mouvements de pivotement dans un plan perpendiculaire à la manette en position de repos.In addition, the member 13 can also be pivotally displaced in the same movements as the lever 11, that is to say, pivoting movements in a plane perpendicular to the lever in the rest position.
Les divers mouvements de la manette 11 et de l'organe rotatif 13 sont transformés en signaux de commande à l'aide d'un circuit électrique 15 qui sera décrit plus en détail plus loin et qui est relié, par exemple via un faisceau de connexion électrique 17 à une unité de traitement et d'exploitation (non représenté) des signaux de commande. Par la suite, on expliquera les divers composants et éléments du dispositif en relation avec les figures 2 à 5.The various movements of the lever 11 and the rotary member 13 are converted into control signals by means of an electrical circuit 15 which will be described in more detail later and which is connected, for example via a connection beam 17 to a processing unit and operating (not shown) control signals. Subsequently, the various components and elements of the device will be explained in relation to FIGS. 2 to 5.
Comme on le voit sur les figures 2 et 3, la manette 11 est maintenue fixe en rotation par un socle de manette 19. Ce socle 11 est mobile sur une course prédéfinie selon une direction parallèle à la manette en position de repos, c'est-à-dire la direction TZl (voir figure 1).As can be seen in FIGS. 2 and 3, the handle 11 is held fixed in rotation by a handle base 19. This base 11 is movable on a predefined stroke in a direction parallel to the handle in the rest position, it is ie the TZl direction (see Figure 1).
A cet effet, la manette de commande 11 présente une extrémité libre 21 qui peut être conformée, selon la conception souhaitée, pour être reliée à un organe de préhension de la manette (non représentée).For this purpose, the control lever 11 has a free end 21 which may be shaped, according to the desired design, to be connected to a gripping member of the handle (not shown).
L'autre extrémité 23 présente une forme sphérique avec deux tétons 25 diamétralement opposés. Ces tétons définissent un axe de pivotement de la manette 11, plus en détail l'axe de pivotement pour les mouvements selon les flèches TXl et TX2. Pour maintenir la manette 11 fixe en rotation, le socle de manette 19 comporte des parois 27 formant des parties en forme de calotte et définissant un logement sphérique 29 pour recevoir l'extrémité sphérique 23 de la manette. Des fentes 31 diamétralement opposées sont délimitées par les parois 29 pour recevoir les deux tétons 25 de manière à bloquer la manette en rotation tout en permettant un mouvement de pivotement de la manette 11 par un mouvement coulissant des tétons dans les fentes. Le mouvement de pivotement ainsi défini est le mouvement selon les directions TYl et TY2 de la figure 1.The other end 23 has a spherical shape with two diametrically opposed studs 25. These nipples define a pivot axis of the handle 11, in more detail the pivot axis for the movements according to the arrows TX1 and TX2. To keep the handle 11 fixed in rotation, the handle base 19 has walls 27 forming cap-shaped portions and defining a spherical housing 29 for receiving the spherical end 23 of the handle. Slots 31 diametrically opposed are delimited by the walls 29 to receive the two pins 25 so as to lock the handle in rotation while allowing a pivoting movement of the handle 11 by a sliding movement of the nipples in the slots. The pivoting movement thus defined is the movement according to the directions TY1 and TY2 of FIG.
Selon une variante non représentée, on peut prévoir des tétons supplémentaires au niveau de la partie sphérique de la manette 11 et des fentes supplémentaires au niveau des parois 27 pour définir des directions de pivotement supplémentaires tout en maintenant la manette fixe en rotation.According to a variant not shown, one can provide additional pins at the spherical portion of the handle 11 and additional slots at the walls 27 to define additional pivoting directions while maintaining the fixed handle in rotation.
Des moyens 35 de guidage du socle 19 en translation sont prévus pour assurer une position stable du socle et ainsi de la manette 11.Means 35 for guiding the pedestal 19 in translation are provided to ensure a stable position of the pedestal and thus of the handle 11.
Ces moyens de guidage 35 du socle sont portés d'une part par la face inférieure 33 du socle 19 et d'autre part par une embase de support 37.These guide means 35 of the base are carried on the one hand by the lower face 33 of the base 19 and on the other hand by a support base 37.
Plus en détail, les moyens de guidage 35 du socle comprennent au moins deux tiges de guidage 39 portées par la face inférieure 33 du socle 19 et coopérant avec deux ouvertures correspondantes 41 ménagées dans l'embase de support.In more detail, the guide means 35 of the base comprise at least two guide rods 39 carried by the lower face 33 of the base 19 and cooperating with two corresponding openings 41 formed in the support base.
Avantageusement les deux tiges 39 comportent à leurs extrémités libres des butées 43 pour limiter la course de déplacement de la manette 11 selon une direction parallèle à la manette en position de repos, c'est-à-dire la direction TZl indiquée sur la figure 1.Advantageously, the two rods 39 comprise at their free ends stops 43 to limit the travel of the handle 11 in a direction parallel to the handle in the rest position, that is to say the direction TZ1 shown in Figure 1 .
Afin de définir une position de repos claire sur cette direction TZl, le dispositif comporte un moyen élastique de repositionnement 45 vers la position de repos, tel qu'un ressort hélicoïdale ou conique (voir en particulier les figures 1 et 5), s'appuyant d'une part sur la face inférieure 33 du socle de manette et d'autre part sur l'embase de support 37.In order to define a clear rest position on this direction TZ1, the device comprises a resilient means for repositioning 45 towards the rest position, such as a helical or conical spring (see in particular FIGS. 1 and 5), supporting on the one hand on the lower face 33 of the handle base and on the other hand on the support base 37.
Pour transmettre l'action d'un utilisateur, le socle 19 porte en outre sur sa face inférieure 33 au moins un, de préférence deux pistons d'actionnement 47, chaque piston étant apte à actionner un interrupteur associé porté par le circuit électrique 15.To transmit the action of a user, the base 19 also bears on its lower face 33 at least one, preferably two actuating pistons 47, each piston being able to actuate an associated switch carried by the electric circuit 15.
Le circuit électrique 15 comprend d'une part une carte à circuit imprimé 49 et d'autre part une membrane souple 51 disposée sur la carte 49, la membrane comportant pour chaque piston 47 un monticule 53 élastique de contactage par un appui d'un piston sur la membrane pour fermer une boucle électrique et délivrer un signal de commande.The electrical circuit 15 comprises on the one hand a printed circuit board 49 and on the other hand a flexible membrane 51 disposed on the board 49, the membrane comprising each piston 47 a contact elastic mound 53 by pressing a piston on the membrane to close an electric loop and deliver a control signal.
Comme on le voit sur la figure 2, la carte à circuit imprimé 49 présente des plages de contactage 55 avec un motif, par exemple en serpentin, de deux pistes électrique en chevauchement.As can be seen in FIG. 2, the printed circuit board 49 has contact pads 55 with a pattern, for example in a serpentine pattern, of two overlapping electric tracks.
Les monticules 53 comportent à l'intérieur une pastille en métal ou en carbone qui, lorsqu'elle entre en contact avec une plage 55 associée assure le contact électrique entre les deux pistes et réalise ainsi la fermeture d'une boucle électrique et permet donc de délivrer un signal de commande. Dans le cadre de la présente invention, on a également traité le problème de l'éclairage de la manette. Cet aspect de l'invention peut également être considéré de façon indépendante.The mounds 53 comprise inside a pellet made of metal or carbon which, when it comes into contact with an associated pad 55, ensures electrical contact between the two tracks and thus closes an electric loop and thus makes it possible to deliver a control signal. In the context of the present invention, the problem of lighting the controller has also been addressed. This aspect of the invention can also be considered independently.
A cet effet, la manette 11 est réalisée en un matériau transmettant la lumière et la carte à circuit imprimé 49 comporte un moyen d'éclairage tel qu'une diode électroluminescente 57, centré par rapport à l'axe défini par la manette 11 en position de repos.For this purpose, the handle 11 is made of a light transmitting material and the printed circuit board 49 comprises a lighting means such as a light emitting diode 57, centered with respect to the axis defined by the lever 11 in position rest.
Par « matériau transmettant la lumière », on entend aussi bien un matériau transparent qu'un matériau translucide.By "light-transmitting material" is meant both a transparent material and a translucent material.
La membrane 51, l'embase de support 37 et le socle de manette 19 comportent chacun une ouverture centrale portant respectivement les numéros de référence 59The membrane 51, the support base 37 and the handle base 19 each comprise a central opening respectively bearing the reference numerals 59.
(figure 3), 61 (figure 2) et 63 (figure 5). Ces ouvertures définissent un passage de lumière (comme une cheminée de lumière) de manière que la lumière émise par la diode 57 passe par le passage de lumière pour se coupler via l'extrémité sphérique 23 dans la manette de commande 11 et éclaire l'extrémité de préhension 21 de la manette. Cette disposition permet d'assurer un éclairage efficace sans qu'il y ait besoin de connexions électriques ou optiques compliquées entre des pièces mobiles et les pièces statiques.(Figure 3), 61 (Figure 2) and 63 (Figure 5). These openings define a light passage (such as a light stack) so that the light emitted by the diode 57 passes through the light passage to be coupled via the spherical end 23 in the control handle 11 and illuminates the end gripping 21 of the joystick. This arrangement ensures efficient lighting without the need for complicated electrical or optical connections between moving parts and static parts.
Par ailleurs, on constate que la partie sphérique 23 de la manette 11 joue le rôle d'une lentille optique facilitant le couplage de la lumière dans la manette 11 par son angle d'ouverture important qui minimise les pertes de lumière. Enfin, la partie droite de la manette 11 joue le rôle d'un guide d'onde qui confine la lumière à l'intérieur de la manette jusqu'à son expulsion à l'extrémité 21.Furthermore, it is found that the spherical portion 23 of the lever 11 acts as an optical lens facilitating the coupling of the light in the lever 11 by its large opening angle which minimizes light loss. Finally, the right portion of the handle 11 acts as a waveguide which confines the light inside the handle until it is expelled at the end 21.
De préférence, la manette est réalisée en matière plastique, notamment en polycarbonate. Bien entendu, tout autre matériau optiquement transparent ou translucide peut être utilisé.Preferably, the handle is made of plastic, in particular polycarbonate. Of course, any other optically transparent or translucent material may be used.
Après avoir décrit en détail la structure et le fonctionnement de la manette, on se concentre maintenant sur l'organe rotatif de commande 13.After describing in detail the structure and operation of the joystick, we now focus on the rotary control member 13.
Cet organe rotatif 13 est supporté par une liaison à cardan 65 de manière à relier l'organe rotatif 13 en pivotement à la manette de commande 11. Ceci a pour effet que lorsque la manette pivote selon les directions prédéfinies TXl,This rotary member 13 is supported by a cardan link 65 so as to connect the rotary member 13 pivotally to the control lever 11. This has the effect that when the joystick pivots in the predefined directions TX1,
TX2 ainsi que TYl et TY2, l'organe 13 pivote ensemble avec la manette 11.TX2 as well as TY1 and TY2, the member 13 pivots together with the handle 11.
Toutefois, cette liaison est seulement réalisée en pivotement, mais non en rotation, de sorte que l'organe 13 puisse tourner librement alors que la manette 11 est fixe en rotation. Comme on le voit bien sur les figures 2 et 3, l'organe rotatif de commande 13 présente une forme générale d'une cloche dont le sommet 67 présente une ouverture de passage 69 (figure 5) pour la manette de commande 11.However, this connection is only made in rotation, but not in rotation, so that the member 13 can rotate freely while the lever 11 is fixed in rotation. As can be seen in FIGS. 2 and 3, the rotary control member 13 has the general shape of a bell whose apex 67 has a passage opening 69 (FIG. 5) for the control lever 11.
De préférence, l'organe 13 en forme de cloche est surmonté d'un moyen de liaison mécanique 71 avec un élément de préhension de l'organe rotatif (non représenté). A titre d'exemple, les moyens 71 peuvent comprendre des moyens de cϋpsage de vissage ou de collage.Preferably, the bell-shaped member 13 is surmounted by a mechanical connection means 71 with a gripping element of the rotary member (not shown). By way of example, the means 71 may comprise means for screwing or gluing.
La partie en cloche de l'organe 13 présente sur des côtés opposés deux petits axes 73 (figure 2) destinés à coopérer avec deux paliers 75 pratiqués dans un anneau de cardan 77.The bell portion of the member 13 has on opposite sides two small axes 73 (Figure 2) intended to cooperate with two bearings 75 formed in a cardan ring 77.
Cet anneau 77 présente lui-même deux axes 79 de basculement qui sont accrochés via une liaison de clipsage à une pièce 81 appelée « carrousel », pour une raison qui va paraître claire plus loin dans la description, et qui possède une forme circulaire.This ring 77 itself has two tilting axes 79 which are hooked via a clipping link to a part 81 called "carousel", for a reason which will appear clear later in the description, and which has a circular shape.
A cet effet, le carrousel 81 possède deux portiques 83 à palier aptes à recevoir par simple clipsage les axes 79 de l'anneau 77.For this purpose, the carousel 81 has two bearing gantries 83 capable of receiving by simple clipping the axes 79 of the ring 77.
La pièce 81 est appelée « carrousel » car elle est portée libre en rotation par l'embase de support 37. Le carrousel 81 peut donc tourner librement avec l'organe rotatif 13 et maintien la liaison de cardan 65 avec l'organe rotatif de commande 13. On comprend donc aisément qu'un mouvement de rotation appliqué à l'organe 13 est transmis via la liaison à cardan 65 au carrousel 81, ceci de façon indépendante de tout mouvement de pivotement qui peut être appliqué à la manette et donc aussi à l'organe 13.The piece 81 is called "carousel" because it is carried free in rotation by the support base 37. The carousel 81 can therefore rotate freely with the rotary member 13 and maintains the universal joint 65 with the rotary control member 13. It is therefore easily understood that a rotational movement applied to the member 13 is transmitted via the cardan link 65 to the carousel 81, this independently of any pivoting movement that can be applied to the handle and therefore also to the body 13.
Pour limiter la friction en rotation entre le carrousel 81 et l'embase de support 37, l'embase de support comporte sur sa périphérie circulaire des protubérances 83 appelées godrons. Il s'agit en fait de partie de calottes de sorte qu'au niveau de chaque godron, il n'y a qu'un contact ponctuel entre le carrousel 81 et l'embase 37.To limit rotational friction between the carousel 81 and the support base 37, the support base comprises on its circular periphery protrusions 83 called gadroons. It is actually part of caps so that at each gadroon, there is only one point contact between the carousel 81 and the base 37.
L'embase de support comporte en outre des bords 85 de guidage et de centrage du carrousel 81 en rotation. Pour les commandes rotatives via l'organe 13, le dispositif selon l'invention est équipé de moyens 87 de détection du mouvement de rotation du carrousel 81 de maintien.The support base further comprises edges 85 for guiding and centering the carousel 81 in rotation. For rotary controls via the member 13, the device according to the invention is equipped with means 87 for detecting the rotational movement of the carousel 81 for holding.
Avantageusement, ces moyens 87 sont des moyens optiques comme représentés sur la figure 2.Advantageously, these means 87 are optical means as shown in FIG. 2.
A cet effet, les moyens 87 de détection de mouvement de rotation du carrousel 81 comportent des portions d'écrans 89 disposées de façon régulière sur un cercle sur la face inférieure 91 du carrousel 81 et au moins un, de préférence deux composants 93 à barrière de lumière portés par le circuit électrique et disposés de manière que les écrans puissent interrompre un faisceau lumineux de mesure.For this purpose, the means 81 for detecting the rotational movement of the carousel 81 comprise portions of screens 89 arranged in a regular manner on a circle on the lower face 91 of the carousel 81 and at least one, preferably two components 93 with a barrier of light carried by the electric circuit and arranged so that the screens can interrupt a light beam measurement.
Le défilement des écrans devant les cellules 93 crée des signaux carrés qui permettent de mesurer la rotation du carrousel et donc de l'organe rotatif 13.The scrolling of the screens in front of the cells 93 creates square signals which make it possible to measure the rotation of the carousel and thus of the rotary member 13.
Pour détecter le sens de rotation de l'organe rotatif de commande, il s'est avéré judicieux que le dispositif comporte au moins deux composants à barrière de lumière qui sont disposés en décalé.To detect the direction of rotation of the rotary control member, it has been judicious that the device comprises at least two light-barrier components which are arranged in offset.
Selon une variante non représentée, on prévoit à la place des moyens optiques des moyens magnétiques de détection du mouvement de rotation du carrousel.According to a variant not shown, there is provided instead of optical means magnetic means for detecting the rotational movement of the carousel.
On doit aussi constater qu'avantageusement, ces composants sont portés par le même circuit imprimé 49 que les plages de contactage.It should also be noted that advantageously, these components are carried by the same printed circuit 49 as the contact pads.
Il est aussi indiqué que les composants 93 présentent donc la forme d'une fourche qui traverse une ouverture associée 95 de la membrane 51 (voir figure 2). A ce stade, on a expliqué toute la structure et le fonctionnement du dispositif pour les mouvements en TZl et en rotation qui sont entièrement dissociés, même par rapport au mouvement de pivotement que peuvent faire la manette 11 et l'organe 13.It is also indicated that the components 93 therefore have the shape of a fork which passes through an associated opening 95 of the membrane 51 (see FIG. 2). At this stage, the entire structure and operation of the device for the movements in TZ1 and in rotation which are completely dissociated are explained, even with respect to the pivoting movement that the lever 11 and the member 13 can make.
Par la suite, on expliquera comment le dispositif traduit un mouvement de pivotement en des signaux de commande.Thereafter, it will be explained how the device translates a pivoting movement into control signals.
Même si le mouvement de pivotement est défini par la manette de commande 11 , il est transmis via l'organe rotatif de commande 13, en particulier par l'intermédiaire de la périphérie inférieure 97 de la cloche qui définit un bord de commande apte à coopérer avec au moins un interrupteur associé de détection d'un mouvement de pivotement porté par le circuit électrique 49.Even if the pivoting movement is defined by the control lever 11, it is transmitted via the rotary control member 13, in particular via the lower periphery 97 of the bell which defines a control edge able to cooperate. with at least one associated switch for detecting a pivoting movement carried by the electric circuit 49.
Ce circuit 49 comporte quatre interrupteurs doubles 99 disposés par paires sur des côtés opposés par rapport au centre du circuit défini par la manette et définissant des axes perpendiculaires de pivotement.This circuit 49 comprises four double switches 99 arranged in pairs on opposite sides with respect to the center of the circuit defined by the joystick and defining perpendicular axes of pivoting.
En fonctionnement, le bord de commande 97 coopère avec les interrupteurs doubles formés par des plages de contact 99 sur le circuit imprimé 49 et des monticules de contactage 100, ces interrupteurs permettant la détection d'un mouvement de pivotement par l'intermédiaire de pistons 101. On constate que ces interrupteurs sont identiques dans leur structure et leur fonctionnement aux interrupteurs formés par les monticules 53 et les plages de contactage 55. Les pistons 101 sont reçus dans des ouvertures en forme de croix 103 semblables aux formes ménagées dans l'embase 37 pour les pistons d'actionnement 47 du socle de manette 19. Les pistons sont donc guidés en coulissement par l'embase de support 37.In operation, the control edge 97 co-operates with the double switches formed by contact pads 99 on the printed circuit 49 and contact mounds 100, these switches enabling the detection of a pivoting movement by means of pistons 101. It is found that these switches are identical in structure and operation to the switches formed by the mounds 53 and the contact pads 55. The pistons 101 are received in cross-shaped openings 103 similar to the shapes formed in the base 37 for the actuating pistons 47 of the joystick base 19. The pistons are thus slidably guided by the support base 37.
Il est important de constater que grâce à la structure mécanique particulière du dispositif, la partie circuit électrique est largement simplifiée. En effet, tout le circuit électrique se résume à une seule carte à circuit imprimé 49 avec une membrane souple associée 51.It is important to note that thanks to the particular mechanical structure of the device, the electrical circuit part is largely simplified. Indeed, the entire electrical circuit boils down to a single circuit board 49 with an associated flexible membrane 51.
Il n'y a aucun composant électrique disposé sur une pièce mobile ce qui évite tout problème de connexion électrique et augmente la fiabilité et la durée de vie du dispositif.There is no electrical component disposed on a moving part which avoids any problem of electrical connection and increases the reliability and the lifetime of the device.
Enfin, cette décomposition des mouvements de pivotement, d'appui et de rotation pour aboutir soit à la fermeture d'un interrupteur simple en ce qui concerne le pivotement et l'appui, soit à une simple détection via un composant optique pour la rotation, tous les composants étant disposés sur la même carte à circuit imprimé, permet d'atteindre un coût de revient très compétitif.Finally, this decomposition of the pivoting movements, support and rotation to achieve either the closure of a simple switch with respect to pivoting and support, or a simple detection via an optical component for rotation, all components being arranged on the same printed circuit board, makes it possible to achieve a very competitive cost price.
L'utilisation d'interrupteurs doubles aussi bien pour la détection des mouvements en pivotement TXl, TX2 ainsi TYl, TY2 et en appui TZl permet de mieux maîtriser l'effort à fournir par l'utilisateur. De plus, comme il y a une répartition de charge entre deux interrupteurs simples, en particulier au niveau de la membrane souple, la sollicitation mécanique de la membrane est diminuée et le nombre de cycles réalisables se trouve augmenté tout en fournissant un toucher de manœuvre agréable pour l'utilisateur et uniforme. En effet, pour ce type de dispositif de commande électrique, les sensations haptiques et leur maîtrise et reproductibilité sont déterminantes pour un utilisateur. Comme on vient de le voir, pour les mouvements de pivotement et selon la direction TZl, ce sont les monticules 53 et 100 de la membrane souple 51 qui procurent la sensation haptique.The use of double switches both for the detection of pivoting movements TX1, TX2 and TY1, TY2 and support TZ1 makes it possible to better control the effort to be provided by the user. In addition, as there is a load distribution between two single switches, particularly at the level of the flexible membrane, the mechanical stress of the membrane is reduced and the number of cycles achievable is increased while providing a pleasant maneuvering touch for the user and uniform. Indeed, for this type of electrical control device, the haptic sensations and their control and reproducibility are crucial for a user. As we have just seen, for the pivoting movements and in the direction TZ1, it is the mounds 53 and 100 of the flexible membrane 51 which provide the haptic sensation.
Pour l'effet haptique en ce qui concerne le mouvement de rotation, le dispositif 1 comprend en outre des moyens d'indexage du mouvement rotatif de l'organe rotatif 13 de commande.For the haptic effect with regard to the rotational movement, the device 1 further comprises means for indexing the rotary movement of the rotary control member 13.
Selon l'exemple décrit en rapport avec les figures et selon un mode préférentiel, ces moyens d'indexage sont réalisés sous forme de moyens d'indexage magnétiques.According to the example described with reference to the figures and according to a preferred embodiment, these indexing means are made in the form of magnetic indexing means.
Comme on le voit sur les figures 1 et 2, les moyens d'indexage magnétiques comprennent un stator 105 et un rotor 107, chacun étant réalisé sous forme d'un anneau avec des pôles Nord et Sud disposé en alternance.As can be seen in FIGS. 1 and 2, the magnetic indexing means comprise a stator 105 and a rotor 107, each being in the form of a ring with alternating north and south poles.
Ces anneaux sont par exemple réalisés par des matériaux composites et obtenus par un processus de frittage ou de moulage.These rings are for example made by composite materials and obtained by a sintering or molding process.
Le stator 105 est fixé dans le couvercle 7 du boîtier via un mécanisme de cϋpsage formé par exemple d'ergots 109 sur l'anneau 105 et de languettes de cϋpsage 111 réalisées d'une seule pièce avec le couvercle 7.The stator 105 is fixed in the cover 7 of the casing via a capping mechanism formed for example of lugs 109 on the ring 105 and of clipping tabs 111 made in one piece with the cover 7.
Comme l'effet d'indexage se réalise quand les pôles Nord et Sud du rotor et du stator défilent les uns par rapport aux autres, on comprend que la distance entre les anneaux 105 et 107 est un paramètre déterminant pour maîtriser l'effet haptique. Pour s'assurer que cet effet haptique est toujours le même dans le cadre d'une production en grand nombre, le couvercle 7 comporte en outre des moyens de mise en place du stator selon une direction parallèle à la manette de commande en position de repos.Since the indexing effect takes place when the north and south poles of the rotor and the stator move relative to one another, it is understood that the distance between the rings 105 and 107 is a determining parameter for controlling the haptic effect. To ensure that this haptic effect is always the same in the context of a large number of production, the cover 7 further comprises means for setting position of the stator in a direction parallel to the control handle in the rest position.
De préférence, ces moyens de mise en place comprennent des languettes souples 121, réalisées d'une seule pièce avec le couvercle 7 et comportant des extrémités d'appui ponctuel 123 sur le stator. Par cet appui en trois points, on s'assure que le stator est toujours bien mis en place et que la distance entre le stator 105 et le rotor 107 est toujours la même et identique sur toute la circonférence des anneaux 105 et 107.Preferably, these means of implementation comprise flexible tongues 121, made in one piece with the cover 7 and having punctual support ends 123 on the stator. By this support in three points, it is ensured that the stator is always well set up and that the distance between the stator 105 and the rotor 107 is always the same and identical over the entire circumference of the rings 105 and 107.
Quant au rotor 107, celui-ci est fixé au carrousel de maintien 81, de préférence également par des moyens de clipsage, c'est-à-dire par exemple des protubérances 113 réalisées d'une seule pièce avec l'anneau 107 et des portiques souples à chanfrein 115.As for the rotor 107, it is fixed to the holding carousel 81, preferably also by clipping means, that is to say for example protuberances 113 made in one piece with the ring 107 and flexible gantry with chamfer 115.
Pour maintenir la manette et donc aussi l'organe rotatif 13 dans une position stable de repos, le dispositif comprend de plus un ressort conique 117 de maintien en position de repos par rapport à un mouvement de pivotement de l'organe rotatif 13 et de la manette 11. Ce ressort 117 s'appuie d'une part sur le bord supérieur de la cloche de l'organe rotatif et d'autre part sur des moyens de retenue portés par le rotor.To maintain the handle and therefore also the rotary member 13 in a stable rest position, the device further comprises a conical spring 117 for holding in the rest position relative to a pivoting movement of the rotary member 13 and the handle 11. This spring 117 is supported on the one hand on the upper edge of the bell of the rotary member and on the other hand on retaining means carried by the rotor.
Ces moyens de retenue sont réalisés d'une seule pièce avec le rotor et comprennent de préférence des ergots 119.These retaining means are made in one piece with the rotor and preferably comprise lugs 119.
On comprend donc à la lecture de la description ci-dessus que le dispositif présente de nombreux avantages. Parmi ces avantages, on cite en particulier une bonne dissociation au niveau mécanique des divers types de mouvements de commande que sont les mouvements de pivotement, d'appui ou encore de rotation ce qui permet de réaliser une haptique claire et agréable pour l'utilisateur.It is therefore clear from reading the description above that the device has many advantages. Among these advantages, there is mentioned in particular a good dissociation at the mechanical level of the various types of control movements that are pivotal movements, support or rotation which allows a clear and pleasant haptic for the user.
On ajoute aussi le fait que toute électronique est concentrée à un même niveau sur des pièces immobiles sans qu'il y ait besoin de connectiques compliquées.It is also added that all electronics are concentrated at the same level on immobile parts without the need for complicated connectors.
Enfin, une solution judicieuse au niveau de l'éclairage a été également développée et présentée. Finally, a judicious solution in terms of lighting has also been developed and presented.
