Description

SYSTEME DE COMMANDE D'INVERSION D'UN MOTEUR ELECTRIQUE ELECTRIC MOTOR INVERSION CONTROL SYSTEM
La présente invention concerne un système de commande d'inversion d'au moins un moteur électrique et, plus particulièrement, pour la commande d'un rétroviseur extérieur d'une automobile. Lorsque deux rétroviseurs extérieurs droite et gauche sont prévus sur une automobi¬ le, le dispositif selon l'invention permet la commande d'un des rétroviseurs après sélection, au moyen d'un organe sélecteur, du rétroviseur à commander.The present invention relates to a reversing control system for at least one electric motor and, more particularly, for the control of an exterior mirror of an automobile. When two right and left exterior mirrors are provided on an automobile, the device according to the invention allows the control of one of the mirrors after selection, by means of a selector member, of the mirror to be controlled.
Dans ce qui suit, on ne fera pas référence aux divers mouvements du miroir et/ou du rétroviseur, qui peuvent être obtenus par des cinématiques appropriées, étant précisé que la sélection d'une position 1 ou 2 pour chaque rétroviseur permettra d'inverser le sens de rota¬ tion du moteur concerné. il existe déjà des commutateurs pour la commande de rétroviseurs. Généralement, chaque rétroviseur est considéré comme un système indépendant comprenant un commutateur de commande et de sélection des diverses po¬ sitions du rétroviseur, un moteur et au moins un circuit électrique.In what follows, reference will not be made to the various movements of the mirror and / or the rear-view mirror, which can be obtained by appropriate kinematics, it being specified that the selection of a position 1 or 2 for each rear-view mirror will make it possible to reverse the direction of rotation of the motor concerned. there are already switches for controlling mirrors. Generally, each mirror is considered to be an independent system comprising a switch for controlling and selecting the various positions of the mirror, a motor and at least one electrical circuit.
Le commutateur le plus utilisé est un commutateur basculant qui réalise la liaison électrique entre un cir¬ cuit électrique et un moteur associé, le commutateur res¬ tant dans la position adéquate et ramené dans la position neutre à l'aide d'un organe de rappel. Un tel commutateur exige de la part de l'opérateur une action prolongée pour être certain que la conduction électrique est effectuée.The most widely used switch is a tilting switch which makes the electrical connection between an electric circuit and an associated motor, the switch remaining in the appropriate position and brought back to the neutral position using a return member. . Such a switch requires an extended action on the part of the operator to be certain that electrical conduction is carried out.
Un autre commutateur susceptible d'être utilisé est celui qui est du type sensitif ou à action fugitive. L'opérateur, ne connaît pas l'état de conduction électri¬ que sauf à constater visuellement que le bon rétroviseur est commandé.Another switch that can be used is one that is of the sensitive or fleeting action type. The operator does not know the state of electrical conduction except to visually note that the correct mirror is ordered.
Il existe donc un besoin de disposer d'un dispo- sitif capable de sélectionner indépendamment le rétrovi¬ seur droite ou gauche, d'une part, et de prévenir 1'opérateur que la commande du rétroviseur sélectionné est effectuée d'une manière certaine, d'autre part.There is therefore a need to have a device capable of independently selecting the right or left rear view mirror, on the one hand, and of warning the operator that the control of the selected rear view mirror is carried out in a certain manner, on the other hand.
La présente invention a pour objet un système d'inversion d'un moteur électrique, du type comprenant un dispositif de commande comportant un boîtier dans lequel sont disposés une touche de commande basculant autour d'un point de basculement, un palonnier monté libre à pivotement sur un point fixe d'appui lié au boîtier, un support de contacts électriques mobiles actionné par le palonnier, lesdits contacts mobiles coopérant avec des contacts électriques fixes associés à un circuit électrique, qui est caractérisé en ce qu'une lame cloquante est interposée entre le palonnier et le point fixe d'appui, ladite lame se déformant lors du basculement de la touche de commande par l'intermédiaire du palonnier, de manière à obtenir, par un effet tactile, une situation de l'état de conduction électrique entre les contacts fixes et mobiles. un avantage de la présente invention réside dans le fait que la conduction électrique entre les contacts mobiles et fixes est différée jusqu'à ce que la lame clo¬ quante se déforme par 1*action du point fixe d'appui du palonnier, la déformation étant suivie d'un bruit de cloquage et d'une sensation tactile qui informent 1'opé¬ rateur que la conduction électrique est bien effectuée.The subject of the present invention is a reversing system of an electric motor, of the type comprising a control device comprising a housing in which are arranged a control key rocking around a tilting point, a lifting beam mounted free to pivot. on a fixed point of support linked to the housing, a mobile electrical contact support actuated by the lifter, said movable contacts cooperating with fixed electrical contacts associated with an electrical circuit, which is characterized in that a blistering blade is interposed between the lifter and the fixed point of support, said blade being deformed when the control key is tilted by means of the lifter, so as to obtain, by a tactile effect, a situation of the state of electrical conduction between the fixed and mobile contacts. an advantage of the present invention lies in the fact that the electrical conduction between the movable and fixed contacts is deferred until the clo¬ quante blade is deformed by 1 * action of the fixed point of support of the lifter, the deformation being followed by a blistering noise and a tactile sensation which inform the operator that the electrical conduction has been carried out.
Un tel différé est déterminé par 1'effet dif¬ férentiel d'effort de manoeuvre de la lame cloquante utilisée c'est-à-dire, en fait, par la courbe effort/course de la dite lame cloquante.Such a delay is determined by the differential effect of the maneuvering force of the blistering blade used, that is to say, by the force / stroke curve of said blistering blade.
L'effet différentiel est lui-même obtenu par une certaine cambrure de la lame cloquante.The differential effect is itself obtained by a certain camber of the blistering blade.
Un autre avantage important de la présente inven- tion est le faible encombrement du dispositif, notamment lorsqu'il est utilisé pour la commande des rétroviseurs extérieurs d'un véhicule puisqu'aussi bien les moyens de sélection du rétroviseur à commander que la commande du moteur associé au rétroviseur n'occupent qu'un volume réduit, comparé à celui qui est nécessaire dans les systèmes de sélection et de commande actuellement montés sur lesdits véhicules.Another important advantage of the present invention is the small size of the device, in particular when it is used for controlling the exterior mirrors of a vehicle since both the means for selecting the mirror to be controlled and the engine control associated with the mirror occupy only a reduced volume, compared to that which is necessary in the selection and control systems currently mounted on said vehicles.

Le système de sélection et de commutation selon l'invention comprend deux ensembles principaux, lorsqu'il est appliqué à la commande d'au moins les deux rétrovi¬ seurs extérieurs droite et gauche d'un véhicule, un moteur étant associé à un rétroviseur. Une cinématique de déplacement non décrite est associée à chaque moteur et entraîne le rétroviseur considéré suivant deux positions distinctes qui sont désignées dans ce qui suit par posi¬ tions Pi et P2. De ce fait, le rétroviseur gauche, par exemple, peut occuper deux positions Pi et P2/ le passa¬ ge de la position Pi à P2 ou inversement étant assurée, selon 1'invention, en inversant le sens de rotation du moteur qui est associé au rétroviseur gauche. Il en est de même pour le rétroviseur droit. L'ensemble ou dispositif de commande 1 (figures 1 et 2) est incorporé dans une partie 2 d'un boîtier 3. Le dispositif de commande comprend une touche de commande 4 basculant autour d'un axe de pivotement 5 fixe. Sur la face supérieure de la touche de commande 4 sont prévues (figure 1) deux zones 6 et 7 et éventuellement repérées par des flèches 8 de basculement vers l'une ou l'autre position P ou P2. La touche de commande 4 comprend deux doigts d'actionnement 9 qui agissent sur un palonnier 10. Les doigts 9 passent à travers des orifices 11 ménagés dans une paroi de séparation 12 qui constituent une bar¬ rière à 1'entrée de poussières dans 1'espace réservé aux circuits électriques.The selection and switching system according to the invention comprises two main assemblies, when it is applied to the control of at least the two right and left exterior mirrors of a vehicle, an engine being associated with a rear view mirror. Kinematics of displacement not described is associated with each engine and drives the rearview mirror considered according to two distinct positions which are designated in the following by positions Pi and P 2 . Therefore, the left mirror, for example, can occupy two positions Pi and P 2 / the passage from the position Pi to P 2 or vice versa being ensured, according to the invention, by reversing the direction of rotation of the engine which is associated with the left mirror. The same is true for the right mirror. The assembly or control device 1 (FIGS. 1 and 2) is incorporated in a part 2 of a housing 3. The control device comprises a control button 4 rocking around a fixed pivot axis 5. On the upper face of the control button 4 are provided (FIG. 1) two zones 6 and 7 and possibly identified by arrows 8 for tilting towards one or the other position P or P 2 . The control button 4 comprises two actuating fingers 9 which act on a lifting beam 10. The fingers 9 pass through orifices 11 formed in a separation wall 12 which constitute a barrier at the entry of dust into one space reserved for electrical circuits.
Le palonnier 10 est articulé à ses deux extrémi¬ tés 13 et 14 dans des trous oblongs 15 ménagés dans le boîtier 3, et il est monté de façon à posséder un degré de liberté en translation suivant l'axe Y et un degré de liberté en rotation autour des axes Z et X. Au centre du palonnier 10, est ménagé un logement 16 dans lequel est disposée une lame cloquante 17 qui, de préférence, prend appui par deux de ses extrémités 19 sur des zones d'appui 19 ménagées dans le fond du logement 16.The lifter 10 is articulated at its two ends 13 and 14 in oblong holes 15 formed in the housing 3, and it is mounted so as to have a degree of freedom in translation along the Y axis and a degree of freedom in rotation about the axes Z and X. In the center of the lifter 10, is provided a housing 16 in which is disposed a blistering blade 17 which, preferably, is supported by two of its ends 19 on support zones 19 formed in the bottom of housing 16.
La lame cloquante 17 peut être constituée par exemple par une lame courbe ou, de préférence, par une pastille ayant une partie centrale de forme sphérique, l'essentiel étant que la lame cloquante présente une cam- brure appropriée pour engendrer un effet différentiel qui, à son tour, procure l'effet tactile recherché.The blistering blade 17 can be constituted for example by a curved blade or, preferably, by a pellet having a central part of spherical shape, the main thing being that the blistering blade has a cam- suitable burn to generate a differential effect which, in turn, provides the desired tactile effect.
Un type d'effet différentiel est donné par la courbe représentée sur la figure 3 et qui est un diagram- me de l'effort (en Newton) appliqué sur une lame cloquan¬ te en fonction de la course (en mm) ou de la déformation de la cambrure de ladite lame cloquante. L'effort diminue brutalement à partir du point A correspondant à une certaine course, puis tombe jusqu'à une valeur B. Entre les points A et B se produit le déclic qui se matérialise par exemple par un bruit informant 1'opérateur que la liaison électrique recherchée est obtenue. Ainsi, l'effet différentiel est donné par les différences en ordonnées et en abscisses des points A et B. A partir du point B, quel que soit l'effort appliqué, la membrane cloquante ne se déforme pratiquement plus. Bien évidemment, on peut choisir d'autres courbes que celle représentée sur la figure 3, en fonction de la membrane cloquante utilisée et de l'effet tactile recherché. La lame cloquante 17 et le logement 16 du palon¬ nier 10 sont tels que la lame cloquante, après déforma¬ tion, ne touche pas le fond 20 du logement 16, de manière que la lame cloquante 17 puisse se déformer librement et qu'une action prolongée sur le palonnier 10 n'amène pas la lame cloquante en contact avec le fond 20 du logement 16. Dans ces conditions, les dimensions de la lame clo¬ quante 17 et du logement 16 sont telles qu'un espace est ménagé entre le fond et le sommet de la lame cloquante après déformation maximum de cette dernière. La lame cloquante 17 repose en son centre sur un doigt de support 53 à sommet 54 arrondi et qui fait par¬ tie intégrante avec le fond 27 du boîtier ou qui pourrait être rapporté si cela s'avérait être plus judicieux. De préférence, le sommet 54 est aligné avec l'axe de pivote- ment ou de basculement 5 de la touche de commande 4, comme cela est matérialisé par la ligne 55.A type of differential effect is given by the curve shown in FIG. 3 and which is a diagram of the force (in Newton) applied to a cloquan¬ te blade as a function of the stroke (in mm) or of the deformation of the camber of said blistering blade. The force decreases abruptly from point A corresponding to a certain travel, then falls to a value B. Between points A and B occurs the click which materializes for example by a noise informing the operator that the connection sought electric is obtained. Thus, the differential effect is given by the differences on the ordinate and on the abscissa of points A and B. From point B, whatever the force applied, the blistering membrane hardly deforms any more. Obviously, one can choose other curves than that shown in Figure 3, depending on the blistering membrane used and the desired tactile effect. The blistering blade 17 and the housing 16 of the palon¬ deny 10 are such that the blistering blade, after deformation, does not touch the bottom 20 of the housing 16, so that the blistering blade 17 can deform freely and that a prolonged action on the lifting beam 10 does not bring the blistering blade in contact with the bottom 20 of the housing 16. Under these conditions, the dimensions of the clo¬ quante blade 17 and of the housing 16 are such that a space is provided between the bottom and top of the blistering blade after maximum deformation of the latter. The blistering blade 17 rests in its center on a support finger 53 with a rounded top 54 and which forms an integral part with the bottom 27 of the housing or which could be added if this turned out to be more judicious. Preferably, the vertex 54 is aligned with the pivoting or tilting axis 5 of the control button 4, as shown by line 55.
Une lame souple à plusieurs branches 21 porte des contacts mobiles 22, 23 et elle est montée dans un loge¬ ment 28 solidaire du fond 27 du boîtier, par tout moyen approprié. Les contacts mobiles 22, 23 coopèrent avec des contacts fixes 24, 25 qui sont prévus sur un circuit découpé 26 qui est fixé sur le fond 27 par sertissage, par exemple, pour établir une connexion électrique sur un circuit imprimé 26 qui est maintenu par serrage sur des pions de positionnement appartenant au fond 27. Lorsque le dispositif selon l'invention est utilisé pour la commande de deux rétroviseurs à deux positions chacun, par exemple gauche et droite, alors on utilise deux lames souples 21, quatre contacts fixes et quatre contacts mobiles, deux contacts mobiles 22 étant prévus d'un même côté pour coopérer avec deux contacts fixes 24 alors que les deux autres contacts mobiles 23 sont de l'autre côté et coopèrent avec deux contacts fixes 26. Les lames souples 21 sont en contact au centre avec le circuit imprimé 26 grâce à une liaison appropriée 28.A flexible blade with several branches 21 carries movable contacts 22, 23 and it is mounted in a housing 28 integral with the bottom 27 of the housing, by any suitable means. The movable contacts 22, 23 cooperate with fixed contacts 24, 25 which are provided on a cut circuit 26 which is fixed on the bottom 27 by crimping, for example, to establish an electrical connection on a printed circuit 26 which is held by tightening on positioning pins belonging to the bottom 27. When the device according to the invention is used for the control of two mirrors with two positions each, for example left and right, then two flexible blades 21 are used, four fixed contacts and four contacts movable, two movable contacts 22 being provided on the same side to cooperate with two fixed contacts 24 while the other two movable contacts 23 are on the other side and cooperate with two fixed contacts 26. The flexible blades 21 are in contact with center with the printed circuit 26 by means of an appropriate connection 28.
Un connecteur électrique 29 est monté à la partie inférieure du boîtier 3 par deux pattes de clipsage 30. Les queues ou languettes de connexion du circuit découpé 25 sont soudées au connecteur 29. Des diodes électroluminescentes 31 sont prévues pour éclairer les indications portées par la touche de commande 4, et sont alimentées en énergie électrique.An electrical connector 29 is mounted on the lower part of the housing 3 by two clip tabs 30. The tails or connection tabs of the cut-out circuit 25 are soldered to the connector 29. Light-emitting diodes 31 are provided to light the indications carried by the key. 4, and are supplied with electrical energy.
Dans une partie 32 de l'ensemble de commande selon l'invention est également prévu un dispositif de sélection 34 du rétroviseur gauche ou droite.In a part 32 of the control assembly according to the invention is also provided a device 34 for selecting the left or right mirror.
Le dispositif de sélection 34 (figures 4 et 5) comprend un corps 35 au-dessus duquel est montée une touche de sélection 36 qui est articulée autour d'un axe 37 et qui peut donc occuper une première position neutre horizontale dans laquelle aucun des rétroviseurs ne peut être commandé, une deuxième position correspondant au rétroviseur droit ou une troisième position correspondant au rétroviseur gauche.The selection device 34 (Figures 4 and 5) comprises a body 35 above which is mounted a selection button 36 which is articulated around an axis 37 and which can therefore occupy a first horizontal neutral position in which none of the mirrors can not be ordered, a second position corresponding to the right mirror or a third position corresponding to the left mirror.
La touche de sélection 36 est munie d'une cheminée centrale 38 dans laquelle est inséré un doigt de manoeuvre creux 39. Un ressort 40 est logé dans le doigt de manoeuvre 39 et assure l'appui des extrémités infé¬ rieures 41 du doigt de manoeuvre 39 sur deux basculeurs 42 constitués chacun par une lame rigide qui comprend une partie droite 43 et une partie gauche 44 munies chacune de rampes ou de cames 45 sur lesquelles se déplacent les extrémités inférieures 41 et qui se terminent à leur extrémité libre par une légère dépression semi-circulaire 46 assurant le contact avec un circuit imprimé 47 disposé dans le boîtier 35. Chaque basculeur 42 possède trois positions stables qui correspondent aux trois états électriques de la touche de sélection 36 et il est exigé pour assurer un bon contact électrique avec le circuit imprimé 47. e doigt de manoeuvre 39 coulisse entre deux faces opposées de la cheminée centrale 38, de manière à supprimer la liberté en translation suivant X. Sur les deux autres faces de la cheminée 38, le doigt de manoeu¬ vre est guidé par les deux génératrices d'une zone cylin- drique 48 ce qui supprime toute liberté en translation suivant Z tout en lui conférant une liberté en rotation autour de X. Cette particularité permet d'assurer l'éga¬ lité des pressions de contact de l'extrémité inférieure 41 sur chacune des parties 43, 44 des basculeurs 42. De plus, le doigt de manoeuvre 39 comprend deux ergots 49 qui sont logés dans deux rainures 50 ménagées dans des parois de la cheminée 38, ceci pour permettre le maintien du doigt de manoeuvre 39 dans la cheminée 38 lors du montage. lorsque la touche de sélection 36 est dans la position neutre, représentée sur la figure 4, aucun des moteurs 51 ou 52 d'entraînement des rétroviseurs (figure 6) ne peut être sollicité même si on appuie sur la touche de commande 4.The selection key 36 is provided with a central chimney 38 into which a hollow operating finger 39 is inserted. A spring 40 is housed in the operating finger 39 and provides support for the lower ends 41 of the operating finger 39 on two rockers 42 each consisting of a rigid blade which comprises a right part 43 and a left part 44 each provided with ramps or cams 45 on which the lower ends move 41 and which terminate at their free end by a slight depression semicircular 46 ensuring contact with a printed circuit 47 disposed in the housing 35. Each rocker 42 has three stable positions which correspond to the three electrical states of the selection key 36 and is required to ensure good electrical contact with the circuit printed 47. e maneuvering finger 39 slides between two opposite faces of the central chimney 38, so as to suppress freedom in tra nslation along X. On the two other faces of the chimney 38, the maneuvering finger is guided by the two generatrices of a cylindrical zone 48 which eliminates any freedom in translation along Z while giving it freedom in rotation around X. This feature makes it possible to ensure the equality of the contact pressures of the lower end 41 on each of the parts 43, 44 of the rockers 42. In addition, the operating finger 39 comprises two lugs 49 which are housed in two grooves 50 formed in the walls of the chimney 38, this to allow the maintenance of the operating finger 39 in the chimney 38 during assembly. when the selection key 36 is in the neutral position, represented in FIG. 4, none of the motors 51 or 52 for driving the mirrors (Figure 6) cannot be used even if the control button 4 is pressed.
Pour une position de la touche de sélection 36 correspondant par exemple au rétroviseur droite, le doigt de manoeuvre 39 fait basculer le basculeur 42 pour amener la dépression ou coupelle 46 correspondante en contact avec le circuit imprimé 47 ; ceci inhibe automatiquement le moteur associé à l'autre rétroviseur, le gauche en l'occurrence.For a position of the selection key 36 corresponding for example to the right rear-view mirror, the actuating finger 39 causes the rocker 42 to tilt to bring the corresponding depression or cup 46 into contact with the printed circuit 47; this automatically inhibits the engine associated with the other mirror, the left in this case.
Une pression exercée sur la touche de commande 4 suivant l'orientation du rétroviseur souhaitée, provoque le déplacement du palonnier 10 et la déformation de lame cloquante 17 comme expliqué à propos de la figure 3. Le contact mobile approprié 22 vient sur le contact fixe en regard 24 et une liaison électrique est réalisée pour que le rétroviseur commandé occupe la position souhaitée.A pressure exerted on the control button 4 according to the orientation of the desired rear-view mirror, causes the movement of the lifter 10 and the deformation of the blistering blade 17 as explained with reference to FIG. 3. The appropriate movable contact 22 comes on the fixed contact at manhole 24 and an electrical connection is made so that the controlled mirror occupies the desired position.
Il va de soi que l'on peut recommencer la manoeu¬ vre pour une autre position du rétroviseur, par appui dans l'autre sens sur la touche de commande 4.It goes without saying that the maneuver can be repeated for another position of the mirror, by pressing the control button 4 in the other direction.
On recommence les manoeuvres pour 1'autre rétro¬ viseur. The maneuvers are repeated for the other rear viewfinder.
