Description

La présente invention concerne un dispositif de commutation électrique et un module comprenant un micro-interrupteur.The present invention relates to an electrical switching device and a module comprising a microswitch.

Elle s'applique en particulier à la commande d'un organe électrique de véhicule automobile.It applies in particular to the control of an electric body of a motor vehicle.

On connaît déjà dans l'état de la technique un dispositif de commutation électrique, du type comprenant un coulisseau monté mobile en translation sur un support, déplaçable longitudinalement par rapport à ce support dans une position de repos, dans une première position active, et dans une seconde position active.Already known in the state of the art an electrical switching device, of the type comprising a slide mounted movable in translation on a support, movable longitudinally relative to the support in a rest position, in a first active position, and in a second active position.

Un tel dispositif est utilisé en particulier pour commander un lève-vitre de véhicule automobile.Such a device is used in particular to control a window lift of a motor vehicle.

En général, le coulisseau comprend des moyens de couplage avec un organe de manoeuvre destiné à être actionné par un utilisateur.In general, the slide comprises coupling means with an operating member intended to be actuated by a user.

Le dispositif comprend des contacts électriques frottants fixe et mobile portés par le support et le coulisseau. Le déplacement relatif de ces contacts permet d'isoler un organe électrique par rapport à une alimentation électrique, de l'alimenter selon un premier sens de circulation du courant, ou bien de l'alimenter selon un second sens de circulation du courant, opposé au premier.The device comprises fixed and movable frictional electrical contacts carried by the support and the slide. The relative displacement of these contacts makes it possible to isolate an electrical member with respect to a power supply, to supply it according to a first direction of flow of the current, or to supply it according to a second direction of circulation of the current, opposite to the first.

La commutation par contacts frottants pose plusieurs problèmes. En effet, il est nécessaire de graisser le coulisseau et le support pour faciliter leur déplacement. De plus, la rupture de contact est relativement lente du fait qu'elle dépend de la vitesse de translation du coulisseau. Enfin, on sait que ce type de commutation est sujet à l'apparition d'arcs électriques, ce qui use les contacts frottants et limite le nombre de cycles de fonctionnements du dispositif de commutation.The switching by rubbing contacts poses several problems. Indeed, it is necessary to grease the slide and the support to facilitate their movement. In addition, the contact break is relatively slow because it depends on the speed of translation of the slide. Finally, it is known that this type of switching is subject to the appearance of arcing, which wears the friction contacts and limits the number of operating cycles of the switching device.

Le document DE 100 32 518 décrit un dispositif selon le préambule de la revendication 1.The document DE 100 32 518 describes a device according to the preamble of claim 1.

La présente invention vise à remédier à ces inconvénients en fournissant un dispositif de commutation plus rapide, plus économique et résistant plus efficacement à l'usure.The present invention aims to overcome these disadvantages by providing a switching device faster, more economical and resistant more effectively to wear.

A cet effet, l'invention concerne un dispositif de commutation du type précité, caractérisé en ce qu'il comprend des premier et second micro-interrupteurs à rupture de contact rapide, munis chacun d'un bouton de commande déplaçable verticalement entre une position de repos et une position active, ce bouton de commande étant manoeuvré par coopération avec un profil de came ménagé sur le coulisseau, de façon que

  • lorsque le coulisseau est dans sa position de repos, les deux boutons de commande sont en position de repos,
  • lorsque le coulisseau est dans sa première position active, le bouton de commande du premier micro-interrupteur est en position active, et
  • lorsque le coulisseau est dans sa seconde position active, le bouton de commande du second micro-interrupteur est dans sa position active.
For this purpose, the invention relates to a switching device of the aforementioned type, characterized in that it comprises first and second microswitches fast contact break, each provided with a control button movable vertically between a position of rest and an active position, this control knob being operated by cooperation with a cam profile formed on the slide, so that
  • when the slide is in its rest position, the two control knobs are in the rest position,
  • when the slider is in its first active position, the control button of the first microswitch is in the active position, and
  • when the slider is in its second active position, the control button of the second microswitch is in its active position.

On entend par micro-interrupteur à rupture de contact rapide un interrupteur dont l'actionnement est très rapide, de façon à avoir une durée d'arc faible.By means of a micro-switch with rapid contact break, a switch whose actuation is very fast is used so as to have a short arc duration.

Un dispositif 10 de commutation électrique selon l'invention, visible sur la figure 1, est destiné à commander un lève-vitre ou un toit ouvrant de véhicule automobile. II comprend un coulisseau 12, monté mobile en translation sur un support 14, suivant la direction longitudinale X dans une position de repos (représentée sur la figure 2), une première position active, et une seconde position active.An electrical switching device 10 according to the invention, visible on the figure 1 , is intended to control a window lifter or a sunroof of a motor vehicle. It comprises a slider 12, mounted to move in translation on a support 14, according to the longitudinal direction X in a rest position (represented on the figure 2 ), a first active position, and a second active position.

Le dispositif de commutation 10 définit globalement un parallélépipède dont la longueur est d'environ 20 mm, la hauteur d'environ 8 mm et la largeur d'environ 8 mm.The switching device 10 generally defines a parallelepiped whose length is about 20 mm, the height of about 8 mm and the width of about 8 mm.

Le coulisseau 12 comprend des moyens 16 de couplage avec un organe de manoeuvre (non représenté) destiné à être actionné par un utilisateur, tel qu'une touche de lève-vitre.The slider 12 comprises means 16 for coupling with an operating member (not shown) intended to be actuated by a user, such as a window lifter button.

Dans ce mode de réalisation, les saillies 42 du support portent à la fois les moyens de positionnement transversal 40 de l'embase et les moyens 44 de guidage du coulisseau.The device 10 also comprises complementary means for guiding the slider 12, more precisely guide means of the groove and tongue type. On the embodiment of Figures 1 to 5 , the guide means are carried by the support 14 and the slider 12. They comprise tabs 44 formed on the projections 42 of the support 14, cooperating with grooves 46 formed on the slider 12. In this embodiment, the projections 42 of the support bear both the transverse positioning means 40 of the base and the means 44 for guiding the slide.

Par ailleurs, le coulisseau 12 comporte un profil de came 56, muni de premier 58 et second 59 bossages, visibles sur la figure 2. Ce profil de came 56 coopère avec chacun des boutons de commande 24, 26 par l'intermédiaire des organes flexibles 30 ou 32.Moreover, the slider 12 comprises a cam profile 56, provided with first 58 and second 59 bosses, visible on the figure 2 . This cam profile 56 cooperates with each of the control buttons 24, 26 via the flexible members 30 or 32.

Le coulisseau 12 comprend également une cavité 60, délimitée par des première 62 et seconde 63 parois transversales. Le coulisseau 12 comprend également deux rampes 64 pour son montage sur le support.The slider 12 also comprises a cavity 60 delimited by first 62 and second 63 transverse walls. The slider 12 also includes two ramps 64 for its mounting on the support.

Les principaux aspects du fonctionnement du dispositif de commutation 10 vont à présent être décrits.The main aspects of the operation of the switching device 10 will now be described.

Le coulisseau est initialement dans sa position de repos, visible sur la figure 2, dans laquelle les deux boutons de commande 24, 26 sont en position de repos.The slide is initially in its rest position, visible on the figure 2 , in which the two control buttons 24, 26 are in the rest position.

Lorsqu'un utilisateur du lève-vitre actionne l'organe de manoeuvre, par exemple en appuyant sur la touche du lève-vitre, les moyens de couplage 16 entraînent le coulisseau 12 de façon à lui faire subir une translation dans la direction longitudinale, par exemple suivant le sens indiqué par la flèche 66.When a user of the window regulator actuates the operating member, for example by pressing the button of the window regulator, the coupling means 16 drive the slider 12 so as to make it undergo a translation in the longitudinal direction, by example following the direction indicated by the arrow 66.

Au cours de cette translation, le premier bouton de commande 24 est manoeuvré par coopération avec le premier bossage 58, par l'intermédiaire de la languette 30. Plus précisément, le bossage 58 impose un mouvement vertical de l'extrémité libre de la languette 30. Lorsque la translation du coulisseau 12 est suffisante, le mouvement vertical de la languette 30 est d'amplitude suffisante pour déplacer le bouton 24 de sa position de repos vers sa position active. Cette position définit la première position active du coulisseau 12.During this translation, the first control knob 24 is operated by cooperation with the first boss 58, via the tongue 30. More specifically, the boss 58 imposes a vertical movement of the free end of the tongue 30 When the translation of the slider 12 is sufficient, the vertical movement of the tongue 30 is of sufficient amplitude to move the button 24 of its rest position to its active position. This position defines the first active position of the slider 12.

Lorsque le coulisseau 12 est déplacé dans le sens opposé à la flèche 66, le second bossage 59 impose un mouvement vertical de l'extrémité libre de la languette 32 et coopère ainsi avec le second bouton de commande 26. Lorsque la translation du coulisseau 12 est suffisante, le bouton 26 passe de sa position de repos vers sa position active, ce qui définit la seconde position active du coulisseau 12.When the slider 12 is moved in the opposite direction to the arrow 66, the second boss 59 imposes a vertical movement of the free end of the tongue 32 and thus cooperates with the second control button 26. When the translation of the slider 12 is sufficient, the button 26 moves from its rest position to its active position, which defines the second active position of the slider 12.

On peut remarquer que, lorsque le coulisseau 12 est dans sa première position active, c'est-à-dire lorsque le premier bouton de commande 24 est en position active, le second bouton de commande 26 est en position de repos. A l'inverse, lorsque le coulisseau est dans sa seconde position active, c'est-à-dire lorsque le second bouton 26 est en position active, le premier bouton de commande 24 est en position de repos.It may be noted that when the slider 12 is in its first active position, that is to say when the first control button 24 is in the active position, the second control button 26 is in the rest position. Conversely, when the slider is in its second active position, that is to say when the second button 26 is in the active position, the first control button 24 is in the rest position.

Par ailleurs, la course du coulisseau 12 est limitée par les deux parois 62, 63 qui coopèrent chacune avec l'une des languettes 30, 32. Ainsi, lorsque le coulisseau 12 est dans sa première position active, déplacé dans le sens de la flèche 66, la paroi 63 forme une butée de fin de course en coopérant avec la languette 32. La course du coulisseau est d'environ 4 mm de chaque côté.Furthermore, the stroke of the slider 12 is limited by the two walls 62, 63 which each cooperate with one of the tongues 30, 32. Thus, when the slider 12 is in its first active position, moved in the direction of the arrow 66, the wall 63 forms a limit stop cooperating with the tongue 32. The stroke of the slide is about 4 mm on each side.

Les principaux aspects du montage du dispositif de commutation 10 vont à présent être décrits.The main aspects of mounting the switching device 10 will now be described.

Tout d'abord, on assemble entre eux les deux modules 17, 18, de façon à former le support 14 visible sur la figure 4. Puis, on monte l'embase 28 sur le support, selon la direction verticale, en faisant tout d'abord passer les saillies 42 à travers des découpes 68 ménagées sur l'embase 28, et en disposant les ailes 38 autour du support 14. Puis, on fait glisser l'embase dans la direction opposée à la direction X, de façon à faire coopérer, d'une part, les bords 41 avec les rainures 40, et d'autre part, la partie transversale 36 avec les butées de positionnement 34. L'embase 28 est ainsi immobilisée dans la direction longitudinale et dans le plan transversal.Firstly, the two modules 17, 18 are assembled together so as to form the visible support 14 on the figure 4 . Then, the base 28 is mounted on the support, in the vertical direction, by first passing the projections 42 through cutouts 68 formed on the base 28, and arranging the wings 38 around the support 14. Then, the base is slid in the direction opposite to the direction X, so as to cooperate on the one hand, the edges 41 with the grooves 40, and on the other hand, the transverse portion 36 with the stops of positioning 34. The base 28 is thus immobilized in the longitudinal direction and in the transverse plane.

On notera que le montage de l'embase 28 sur le support 14 permet d'immobiliser dans la direction verticale les deux supports 17, 18.It will be noted that the mounting of the base 28 on the support 14 makes it possible to immobilize in the vertical direction the two supports 17, 18.

Une fois l'embase montée, on monte le coulisseau 12 sur le support, selon la direction longitudinale, en faisant coopérer tout d'abord les premières languettes 44 du support (à gauche sur la figure 5) avec les rainures 46 du coulisseau 12, puis en faisant glisser le coulisseau 12 jusqu'à sa position de repos une des rampes 64 escamotant la languette 32 visible sur la figure 2.Once the base mounted, is mounted on the slider 12 on the support, in the longitudinal direction, by first cooperating with the first tabs 44 of the support (left on the figure 5 ) with the grooves 46 of the slider 12, then by sliding the slider 12 to its rest position one of the ramps 64 retracting the tongue 32 visible on the figure 2 .

Un dispositif selon un second mode de réalisation est décrit ci-dessous en se référant aux figures 6 et 7. Les éléments analogues aux figures précédentes sont désignés par des références identiques.A device according to a second embodiment is described below with reference to the Figures 6 and 7 . Elements similar to the preceding figures are designated by identical references.

A la différence du premier mode de réalisation, les moyens complémentaires de guidage du coulisseau 12 sont portés par l'embase 28 et le coulisseau 12. Ces moyens de guidage comprennent des languettes 70 ménagées sur des découpes saillantes de l'embase 28, coopérant avec les rainures 46 du coulisseau 48. En outre, les languettes 70 comprennent des extrémités longitudinales 72 destinées à immobiliser les languettes 70 dans les rainures 46.Unlike the first embodiment, the complementary guide means of the slider 12 are carried by the base 28 and the slider 12. These guide means comprise tabs 70 formed on projecting cutouts of the base 28, cooperating with the grooves 46 of the slide 48. In addition, the tongues 70 comprise longitudinal ends 72 intended to immobilize the tongues 70 in the grooves 46.

Le fonctionnement et le montage du dispositif des figures 6 et 7 sont sensiblement similaires à ceux du dispositif des figures 1 à 5. On notera toutefois que le montage du coulisseau 12 sur le support 14 consiste à faire glisser les languettes 70 à l'intérieur des rainures 46 du coulisseau. Les extrémités 72 assurent le positionnement vertical des languettes 70 dans les rainures 46.The operation and assembly of the device Figures 6 and 7 are substantially similar to those of the Figures 1 to 5 . Note however that the mounting of the slider 12 on the support 14 is to slide the tabs 70 within the grooves 46 of the slider. The ends 72 ensure the vertical positioning of the tongues 70 in the grooves 46.

Comme on peut le constater, on dispose grâce à l'invention d'un dispositif de commutation 10 particulièrement performant du fait que l'on utilise des micro-interrupteurs à rupture de contact rapide.As can be seen, it is possible thanks to the invention a switching device 10 particularly effective because we use microswitches break contact fast.

En outre, l'utilisation de deux modules identiques 17, 18 pour former le support 14 est particulièrement intéressante du point de vue des coûts de production, d'autant plus que ces modules 17, 18 peuvent être utilisés comme boîtiers de micro-interrupteurs utilisables pour d'autres dispositifs de commutation que celui objet de l'invention. On peut constater à cet effet que les modules 17, 18 comportent chacun un moyen de détrompage, comprenant un chanfrein, utilisable dans le cas où le module 17, 18 est utilisé de façon isolée.In addition, the use of two identical modules 17, 18 to form the support 14 is particularly interesting from the point of view of production costs, especially since these modules 17, 18 can be used as usable micro-switch boxes. for other switching devices than the subject of the invention. It can be seen for this purpose that the modules 17, 18 each comprise a keying means, comprising a chamfer, usable in the case where the module 17, 18 is used in isolation.
