Description

Le domaine de la présente invention est celui des projecteurs de lumière et, plus particulièrement, celui des projecteurs pour véhicule automobile.The field of the present invention is that of light projectors and, more particularly, that of motor vehicle headlights.

Les projecteurs de véhicule automobile comprennent généralement un réflecteur dans lequel sont disposés une source lumineuse et des moyens de contrôle de la forme du faisceau pour adapter celui-ci aux circonstances de la conduite.Motor vehicle headlamps generally comprise a reflector in which are arranged a light source and means for controlling the shape of the beam to adapt it to the driving circumstances.

Il est connu d'utiliser une barrette de coupure permettant diverses phases d'occultation du faisceau lumineux. La barrette est actionnée électriquement pour se déplacer, sur commande, entre au moins deux positions angulaires dans lesquelles elle occulte plus ou moins le faisceau lumineux. Ceci permet de limiter la portée du projecteur, par exemple à celle des feux de croisement, dite position code, pour ne pas éblouir les conducteurs circulant en sens inverse, ou encore à celle des feux de route, dite position route, dans laquelle il n'y a pas d'occultation.It is known to use a cut-off bar allowing various phases of occultation of the light beam. The bar is electrically actuated to move, on command, between at least two angular positions in which it more or less obscures the light beam. This makes it possible to limit the range of the headlamp, for example to that of dipped beam headlights, called low beam position, so as not to dazzle drivers traveling in the opposite direction, or even to that of main beam headlights, called high beam position, in which it does not there is no concealment.

Un cache fixe est généralement prévu entre la barrette et une lentille du projecteur. Le cache fixe intercepte le faisceau qui passe en dessous de la barrette de coupure. Lorsque la barrette se trouve en position feux de route, elle se positionne entre la source lumineuse et le cache et elle n'intervient pas dans la forme du faisceau. En revanche, lorsque la barrette est en position code, elle intercepte une partie du faisceau lumineux, en plus de celle interceptée par le cache fixe. Il est important dans cette position, que la barrette ne laisse pas passer de lumière entre elle et le cache fixe, afin de ne pas éclairer des zones non souhaitées et de limiter la portée du faisceau correspondant aux feux de croisement.A fixed cover is generally provided between the bar and a lens of the projector. The fixed cover intercepts the beam that passes below the cut-off bar. When the bar is in the main beam position, it is positioned between the light source and the cover and it does not affect the shape of the beam. On the other hand, when the strip is in the dipped position, it intercepts part of the light beam, in addition to that intercepted by the fixed cover. In this position, it is important that the strip does not allow light to pass between it and the fixed cover, so as not to illuminate unwanted areas and to limit the range of the beam corresponding to dipped headlights.

Les dispositifs de l'art antérieur qui commandent la position de la barrette sont généralement constitués par un moteur d'actionnement associé à un capteur de la position de la barrette de coupure ou à une butée qui définit la position de repos de la barrette. Pour des raisons de sécurité cette position de repos est associée à la position code, afin d'éviter un éblouissement des conducteurs venant en sens inverse dans le cas d'une panne du dispositif d'actionnement de la barrette. Le rappel sur la position de butée ou sur la position extrême est généralement assuré par un ressort. Cette configuration a pour inconvénient qu'elle nécessite un ressort de fort couple de rappel afin de réduire le temps de réaction du mouvement de la barrette et par conséquent d'un moteur de taille relativement importante pour contrer ce ressort.The devices of the prior art which control the position of the bar generally consist of an actuation motor associated with a sensor of the position of the cut-off bar or with a stop which defines the rest position of the bar. For safety reasons, this rest position is associated with the dipped position, in order to avoid dazzling drivers coming in the opposite direction in the event of a failure of the bar actuating device. The return to the stop position or to the extreme position is generally ensured by a spring. This configuration has the drawback that it requires a high return torque spring in order to reduce the reaction time of the movement of the strip and consequently a relatively large motor to counter this spring.

Une solution à base d'attraction magnétique de la barrette par un aimant a été envisagée mais elle se heurte au risque de démagnétisation des composants utilisés car la température au niveau de la barrette peut dépasser, dans le cas d'une lampe à halogènes, la valeur de 250° au delà de laquelle les éléments aimantés perdent leur propriété magnétique. Avec l'apparition de lampes de nouvelle technologie, cette valeur a été réduite et l'option magnétique peut être reconsidérée.A solution based on magnetic attraction of the bar by a magnet has been considered but it comes up against the risk of demagnetization of the components used because the temperature at the bar can exceed, in the case of a halogen lamp, the value of 250° beyond which the magnetized elements lose their magnetic property. With the appearance of new technology lamps, this value has been reduced, and the magnetic option can be reconsidered.

On connaît, par les documents EP2405190A1 et DE19708111A1 , des dispositifs de projecteur pour véhicule comportant des électro-aimants permettant d'ajuster la position d'un cache mobile. Toutefois, ces solutions ne sont pas complètement satisfaisantes.We know from the documents EP2405190A1 And DE19708111A1 , headlamp devices for a vehicle comprising electromagnets making it possible to adjust the position of a movable cover. However, these solutions are not completely satisfactory.

La présente invention a pour but de proposer un mécanisme de commande d'une barrette de coupure qui tire le meilleur parti de la réduction de température associée à la mise en oeuvre de nouvelles lampes qui ont une pouvoir calorifique plus faible, en termes de nombre de pièces, d'encombrement et/ou de prix des éléments qui le constitue.The object of the present invention is to provide a switch bar control mechanism which makes the most of the temperature reduction associated with the implementation of new lamps which have a lower calorific value, in terms of the number of parts, size and/or price of the elements that constitute it.

A cet effet, selon un premier mode de réalisation de l'invention, l'invention a pour objet un mécanisme de coupure pour projecteur de véhicule automobile comprenant une barrette formée par une plaque d'obturation portée par un équipage mobile configuré pour déplacer ladite plaque dans un plan et ainsi obturer plus ou moins un faisceau lumineux de manière à changer de mode de fonctionnement optique, comprenant en outre un mécanisme d'actionnement dudit équipage mobile à l'aide d'un électro-aimant comportant une bobine d'induction associée à un noyau ferromagnétique, ledit électro-aimant comprenant au moins un noyau ferromagnétique fixe par rapport à sa bobine d'induction, ledit équipage mobile comprenant au moins un aimant permanent configuré pour coopérer magnétiquement avec ledit noyau ferromagnétique, et ledit aimant permanent étant attiré en direction dudit noyau ferromagnétique en absence de circulation d'un courant dans ladite bobine d'induction, ledit aimant permanent étant repoussé à distance du noyau ferromagnétique lorsqu'un courant circule dans ladite bobine d'induction.To this end, according to a first embodiment of the invention, the subject of the invention is a switch-off mechanism for a motor vehicle headlamp comprising a bar formed by a blanking plate carried by a mobile assembly configured to move said plate in a plane and thus more or less block a light beam so as to change the optical operating mode, further comprising a mechanism for actuating said movable assembly using an electromagnet comprising an associated induction coil to a ferromagnetic core, said electromagnet comprising at least one ferromagnetic core fixed with respect to its induction coil, said moving assembly comprising at least one permanent magnet configured to cooperate magnetically with said ferromagnetic core, and said permanent magnet being attracted direction of said ferromagnetic core in the absence of flow of a current in said induction coil, said permanent magnet being pushed away from the ferromagnetic core when a current flows in said induction coil.

L'utilisation de l'attraction ou la répulsion magnétique, qui est rendue possible par l'apparition des lampes remplaçant les lampes halogènes, permet de rendre les moyens de mise en mouvement d'une barrette de coupure plus légers et moins complexes que les moyens traditionnels.The use of magnetic attraction or repulsion, which is made possible by the appearance of lamps replacing halogen lamps, makes it possible to make the means for setting a switch bar in motion lighter and less complex than the means traditional.

De plus, cette solution permet de répondre facilement au problème d'un retour dans une position de repos correspondant à la position code, dans le cas d'une panne de la commande de positionnement de la barrette.In addition, this solution makes it possible to easily respond to the problem of a return to a rest position corresponding to the code position, in the event of a failure of the bar positioning control.

Dans un mode particulier de réalisation ledit noyau ferromagnétique est un cylindre positionné à l'intérieur de ladite bobine et l'aimant permanent est un cylindre positionné dans l'alignement dudit noyau.In a particular embodiment, said ferromagnetic core is a cylinder positioned inside said coil and the permanent magnet is a cylinder positioned in alignment with said core.

Avantageusement ladite plaque d'obturation est en position de code lorsque ledit aimant est collé audit noyau ferromagnétique.Advantageously, said closing plate is in the code position when said magnet is glued to said ferromagnetic core.

Dans un mode particulier de réalisation ledit aimant permanent est poussé en direction dudit noyau ferromagnétique par un ressort de rappel. Cette solution permet d'éviter de mettre en oeuvre une force d'attraction trop importante et donc permet de choisir un aimant de relativement petite taille.In a particular embodiment, said permanent magnet is pushed in the direction of said ferromagnetic core by a return spring. This solution makes it possible to avoid using too great an attraction force and therefore makes it possible to choose a magnet of relatively small size.

De façon préférentielle la force de répulsion dudit aimant par ledit noyau ferromagnétique lorsqu'un courant circule dans ladite bobine d'induction, est supérieure à la force dudit ressort de rappel.Preferably, the force of repulsion of said magnet by said ferromagnetic core when a current flows in said induction coil is greater than the force of said return spring.

Dans un second mode de réalisation de l'invention, l'invention a pour objet un mécanisme de coupure pour projecteur de véhicule automobile comprenant une barrette formée par une plaque d'obturation portée par un équipage mobile configuré pour déplacer ladite plaque dans un plan et ainsi obturer plus ou moins un faisceau lumineux de manière à changer de mode de fonctionnement optique, comprenant en outre un mécanisme d'actionnement dudit équipage mobile à l'aide d'un électro-aimant comportant une bobine d'induction associée à une carcasse métallique réalisée en matériau ferromagnétique, ledit électro-aimant comprenant au moins un noyau ferromagnétique fixe par rapport à sa bobine d'induction, ledit équipage mobile comprenant au moins un aimant permanent configuré pour coopérer magnétiquement avec ladite carcasse métallique réalisée en matériau ferromagnétique, ledit mécanisme de coupure étant tel que :

  • la distance entre ledit aimant permanent et ladite carcasse métallique réalisée en matériau ferromagnétique est constante au cours du déplacement de ladite plaque d'obturation ; et
  • ladite carcasse métallique réalisée en matériau ferromagnétique s'étend selon deux montants latéraux laissant entre eux une forme cylindrique creuse et dans lequel l'aimant permanent est un cylindre positionné de façon libre en rotation dans ladite forme cylindrique creuse. Cela permet de garder une force d'attraction minimale de l'aimant permanent sur le noyau ferromagnétique, après sa répulsion par la bobine d'induction.
In a second embodiment of the invention, the subject of the invention is a switch-off mechanism for a motor vehicle headlamp comprising a bar formed by a blanking plate carried by a mobile assembly configured to move said plate in a plane and thus more or less blocking a light beam so as to change the optical operating mode, further comprising a mechanism for actuating said movable assembly using an electromagnet comprising an induction coil associated with a metal carcass made of ferromagnetic material, said electromagnet comprising at least one ferromagnetic core fixed with respect to its induction coil, said moving assembly comprising at least one permanent magnet configured to cooperate magnetically with said metal carcass made of ferromagnetic material, said cut being such that:
  • the distance between said permanent magnet and said metal carcass made of ferromagnetic material is constant during movement of said blanking plate; And
  • said metal carcass made of ferromagnetic material extends along two lateral uprights leaving between them a hollow cylindrical shape and in which the permanent magnet is a cylinder positioned freely in rotation in said hollow cylindrical shape. This makes it possible to keep a minimum force of attraction of the permanent magnet on the ferromagnetic core, after its repulsion by the induction coil.

Préférentiellement les deux pôles magnétiques dudit aimant permanent sont sensiblement alignés en direction des montants latéraux quand la bobine d'induction n'est pas alimentée en courant électrique.Preferably the two magnetic poles of said permanent magnet are substantially aligned in the direction of the side uprights when the induction coil is not supplied with electric current.

Les deux pôles ne sont toutefois pas rigoureusement alignés pour éviter que sous l'effet d'un courant électrique dans la bobine d'induction de l'électroaimant, l'équipage mobile n'aille aléatoirement dans une direction ou dans l'autre. En gardant un léger écart angulaire avec l'alignement parfait on impose le sens de rotation de la barrette lorsqu'on envoie un courant électrique de commande.However, the two poles are not strictly aligned to prevent the mobile assembly from moving randomly in one direction or the other under the effect of an electric current in the induction coil of the electromagnet. keeping a slight distance angular with perfect alignment, the direction of rotation of the strip is imposed when an electric current is sent.

Dans un mode particulier de réalisation ledit équipage mobile est un axe solidaire en rotation dudit aimant permanent.In a particular embodiment, said moving assembly is an axis integral in rotation with said permanent magnet.

Avantageusement ledit axe porte un doigt configuré pour venir en butée contre au moins une première butée portée par une structure fixe dudit mécanisme, ladite butée définissant la position de quasi alignement des pôles magnétiques de l'aimant permanent en direction desdits montants latéraux. On définit de cette façon, avec précision, la position de repos de la barrette et donc le positionnement du faisceau en position code.Advantageously, said shaft carries a finger configured to come into abutment against at least a first abutment carried by a fixed structure of said mechanism, said abutment defining the position of quasi alignment of the magnetic poles of the permanent magnet in the direction of said lateral uprights. In this way, the rest position of the bar and therefore the positioning of the beam in the code position are defined with precision.

De façon plus avantageuse ledit axe porte un doigt configuré pour venir en butée contre au moins une seconde butée portée par une structure fixe dudit mécanisme, ladite butée définissant une position extrême pour le déplacement de ladite plaque d'obturation. On définit de cette façon, avec précision, la position du faisceau en position de route.More advantageously, said shaft carries a finger configured to come into abutment against at least one second abutment carried by a fixed structure of said mechanism, said abutment defining an extreme position for the displacement of said closing plate. In this way, the position of the beam in the driving position is defined with precision.

Dans un mode particulier de réalisation le retour de ladite barrette vers une position de code à la coupure du courant dans la bobine est accéléré par un ressort de rappel. Cette solution permet d'éviter de mettre en oeuvre une force d'attraction trop importante et donc permet de choisir un aimant de relativement petite taille.In a particular embodiment, the return of said bar to a code position when the current in the coil is cut off is accelerated by a return spring. This solution makes it possible to avoid using too great an attraction force and therefore makes it possible to choose a magnet of relatively small size.

Dans la description qui va suivre, les références longitudinales ou latérales se comprennent en référence à l'axe optique du réflecteur et les termes avant ou arrière renvoient à la direction dans laquelle se propage le faisceau lumineux.In the following description, the longitudinal or lateral references are understood with reference to the optical axis of the reflector and the terms front or rear refer to the direction in which the light beam propagates.

En se référant à la figure 1, on voit la partie avant d'un projecteur de véhicule automobile comprenant un porte-lentille 1 de forme cylindrique qui s'étend vers l'avant à partir d'une armature 2 de forme rectangulaire. Celle-ci s'étend dans un plan perpendiculaire à l'axe optique du faisceau et est découpée en son centre pour laisser passer ledit faisceau. Sur cette armature est fixé le mécanisme de coupure dont la fonction est d'obturer plus ou moins le faisceau en fonction des conditions de circulation du véhicule. De façon non visible, sont disposés en arrière de cette armature, une source lumineuse génératrice du faisceau et un réflecteur qui oriente ce faisceau vers l'avant et vers la lentille (non illustrée) qui est installée à l'extrémité avant du porte-lentille 1.By referring to the figure 1 , we see the front part of a motor vehicle headlamp comprising a lens holder 1 of cylindrical shape which extends forwards from a frame 2 of rectangular shape. This extends in a plane perpendicular to the optical axis of the beam and is cut out at its center to allow said beam to pass. On this frame is fixed the cut-off mechanism whose function is to more or less block the beam depending on the vehicle traffic conditions. In a non-visible way, are arranged behind this frame, a light source generating the beam and a reflector which directs this beam forwards and towards the lens (not shown) which is installed at the front end of the lens holder 1.

En se référant aux figures 2 et 3 on voit, en vue de face, respectivement en position de route et en position de code, le mécanisme de coupure 3 qui est monté en position basse sur l'armature 2. Cette armature comporte, ici en partie basse de sa découpe centrale un cache fixe 4 qui obture en partie cette découpe et devant lequel peut se mouvoir une barrette de coupure 5 pour moduler la forme du faisceau en sortie du projecteur. Cette barrette 5 est mobile en rotation dans un plan perpendiculaire au faisceau lumineux et est mue par un moteur d'actionnement 6.By referring to figures 2 and 3 we see, in front view, respectively in the driving position and in the code position, the cut-off mechanism 3 which is mounted in the low position on the armature 2. This armature comprises, here in the lower part of its central cutout, a cover fixed 4 which partially closes off this cutout and in front of which a cut-off bar 5 can move to modulate the shape of the beam exiting the headlamp. This bar 5 is rotatable in a plane perpendicular to the light beam and is driven by an actuating motor 6.

Sur la figure 2, correspondant à la position de route, la barrette est escamotée, c'est-à-dire qu'elle est inclinée vers le bas et laisse apparaître le cache fixe 4, ce qui laisse passer la quasi-totalité du faisceau lumineux. Sur la figure 3, correspondant à la position code, la barrette est relevée et elle coupe le faisceau sur une plus grande hauteur que ne le ferait le seul cache fixe 4. Après son renversement par la lentille, le faisceau est alors orienté vers le bas, ce qui évite d'éblouir les conducteurs des véhicules venant en sens inverse. La figure 4 montre le mécanisme de coupure 3 dans un premier mode de réalisation, et il est illustré de façon éclatée sur la figure 6. Il comporte un châssis 7 destiné, d'une part, à porter tous les éléments du mécanisme 3 et, d'autre part, à fixer ce mécanisme sur l'armature 2 du projecteur du véhicule. Ce châssis est formé par une platine rectangulaire 71 de laquelle s'étendent deux bras 72 se projetant perpendiculairement à partir de la platine pour porter deux tourillons 73. Ces tourillons forment le support d'un axe de rotation de la barrette de coupure 5, comme cela sera expliqué en détail plus loin. La platine 71 est, par ailleurs, percée de fentes par lesquelles passeront des moyens, du type vis, pour la fixation du mécanisme de coupure 3 sur l'armature 2.On the figure 2 , corresponding to the road position, the bar is retracted, that is to say it is inclined downwards and reveals the fixed cover 4, which allows almost all of the light beam to pass. On the picture 3 , corresponding to the code position, the bar is raised and it cuts the beam over a greater height than would the single fixed cover 4. After its reversal by the lens, the beam is then oriented downwards, which avoids dazzle drivers of oncoming vehicles. There figure 4 shows the cut-off mechanism 3 in a first embodiment, and it is illustrated in an exploded view on the figure 6 . It comprises a frame 7 intended, on the one hand, to carry all the elements of the mechanism 3 and, on the other hand, to fix this mechanism on the frame 2 of the headlight of the vehicle. This frame is formed by a rectangular plate 71 from which extend two arms 72 projecting perpendicularly from the plate to carry two trunnions 73. These trunnions form the support for an axis of rotation of cut-off bar 5, as will be explained in detail below. The plate 71 is, moreover, pierced with slots through which will pass means, of the screw type, for fixing the cut-off mechanism 3 on the armature 2.

Sur le châssis 7 est fixée une carcasse métallique 8 qui forme un berceau pour un électroaimant 9 et qui forme avec lui le moteur d'actionnement 6. La carcasse 8 assure un bouclage magnétique pour l'électroaimant 9. Elle a une forme parallélépipédique dont deux faces sont découpées pour laisser un libre accès aux extrémités longitudinales de l'électroaimant 9. Celui-ci comprend une bobine d'induction 91 formée par des spires qui sont alimentées en courant électrique pour actionner le moteur, et un noyau ferromagnétique 92 placé au centre du bobinage 91. Ce noyau est fixe longitudinalement dans la bobine et a pour fonction, dans un premier temps de servir de point d'attraction pour une force exercée par un aimant permanent lorsque la bobine n'est pas alimentée et dans un deuxième temps de repousser cet aimant permanent lorsque la bobine est alimentée.On the frame 7 is fixed a metal carcass 8 which forms a cradle for an electromagnet 9 and which forms with it the actuating motor 6. The carcass 8 provides magnetic looping for the electromagnet 9. It has a parallelepiped shape of which two faces are cut to leave free access to the longitudinal ends of the electromagnet 9. The latter comprises an induction coil 91 formed by turns which are supplied with electric current to actuate the motor, and a ferromagnetic core 92 placed in the center of the coil 91. This core is fixed longitudinally in the coil and has the function, first of all, of serving as a point of attraction for a force exerted by a permanent magnet when the coil is not powered and secondly of repel this permanent magnet when the coil is energized.

La barrette de coupure 5 comprend une plaque plane 51 d'obturation du faisceau qui s'étend, transversalement, sur une longueur lui permettant d'occulter le faisceau sur toute sa largeur et dont la forme de son arête supérieure correspond à la forme que l'on souhaite donner au faisceau en position de code. Cette plaque d'obturation 51 est portée par un support de plaque 52 formé autour d'un axe de rotation 53 qui est orienté selon une direction perpendiculaire à la plaque d'obturation 51 de façon à permettre la rotation de celle-ci dans son plan. Le support de plaque 52 comprend, en s'étendant à partir de l'axe de rotation 53, d'une part, des moyens de fixation de la plaque d'obturation 51 et, d'autre part, des moyens de fixation d'un premier aimant permanent 54. Cet aimant permanent 54 a une forme cylindrique dont le diamètre est sensiblement égal à celui du noyau ferromagnétique 92. Par ailleurs, le support de plaque 52 est conformé de façon que le premier aimant permanent 54 soit sensiblement aligné avec ce noyau lorsque l'axe de rotation 53 est monté sur les tourillons 73 du châssis 7. De la sorte l'aimant permanent est naturellement attiré par le noyau ferromagnétique, qui est fixe, et tend à faire tourner la plaque d'obturation vers le haut, en absence de tout courant qui circule dans la bobine d'induction 91.The cut-off strip 5 comprises a flat plate 51 for blocking the beam which extends, transversely, over a length allowing it to obscure the beam over its entire width and the shape of its upper edge of which corresponds to the shape that the 'we want to give the beam in code position. This blanking plate 51 is carried by a plate support 52 formed around an axis of rotation 53 which is oriented in a direction perpendicular to the blanking plate 51 so as to allow rotation of the latter in its plane. . The plate support 52 comprises, extending from the axis of rotation 53, on the one hand, means for fixing the blanking plate 51 and, on the other hand, means for fixing a first permanent magnet 54. This permanent magnet 54 has a cylindrical shape whose diameter is substantially equal to that of the ferromagnetic core 92. Furthermore, the plate support 52 is shaped so that the first permanent magnet 54 is substantially aligned with this core when the axis of rotation 53 is mounted on the journals 73 of the frame 7. In this way the permanent magnet is naturally attracted by the ferromagnetic core, which is fixed, and tends to rotate the shutter plate upwards , in the absence of any current flowing through the induction coil 91.

La figure 5 montre une variante du premier mode de réalisation, dans laquelle un ressort de rappel est ajouté pour aider le retour de la barrette vers la position de code. En effet, après le passage d'un courant dans la bobine, l'aiment permanent 54 est repoussé à distance du noyau ferromagnétique et la force d'attraction de l'un sur l'autre, qui est proportionnelle au carré de la distance qui les sépare, diminue fortement. Lors de la coupure du courant dans la bobine il se peut que cette force soit insuffisante pour ramener l'aimant permanent, et, par suite, la barrette de coupure 5, vers la position de code, ou tout au moins pour le ramener suffisamment rapidement. Le mouvement de la barrette risque en effet d'être trop lent pour être compatible des temps de réaction imposés à un feu de véhicule. La variante consiste ainsi à aider ce retour par l'introduction d'un ressort de rappel 75 qui est positionné sur un des bras d'extension 72 du châssis 7 et qui complémente la force d'attraction magnétique. Dans la configuration représentée ce ressort est un ressort spiral qui agit en écartement et qui, pour cela, prend appui sur deux becquets 74 positionnés respectivement sur le bras d'extension 72 qui est porteur du ressort et sur la plaque d'obturation 51 de la barrette.There figure 5 shows a variant of the first embodiment, in which a return spring is added to help the bar return to the code position. Indeed, after the passage of a current in the coil, the permanent magnet 54 is pushed away from the ferromagnetic core and the force of attraction of one on the other, which is proportional to the square of the distance which separates them, decreases sharply. When breaking the current in the coil it may be that this force is insufficient to bring the permanent magnet, and, consequently, the cut-off strip 5, towards the code position, or at least to bring it back sufficiently quickly. The movement of the bar indeed risks being too slow to be compatible with the reaction times imposed on a vehicle fire. The variant thus consists in helping this return by introducing a return spring 75 which is positioned on one of the extension arms 72 of the frame 7 and which complements the magnetic attraction force. In the configuration shown, this spring is a spiral spring which acts as a spacer and which, for this, rests on two spoilers 74 positioned respectively on the extension arm 72 which carries the spring and on the blanking plate 51 of the barrette.

En se référant aux figures 7 à 9, on va maintenant décrire un deuxième mode de réalisation. Les éléments de ce mode qui sont identiques au premier mode de réalisation sont désignés par le même chiffre de référence et ne sont pas décrits à nouveau.By referring to figures 7 to 9 , a second embodiment will now be described. Elements of this embodiment which are identical to the first embodiment are denoted by the same reference numeral and are not described again.

La figure 7 montre le mécanisme de coupure 3 en version assemblée, sous la forme d'un boîtier parallélépipédique duquel s'étend latéralement la plaque d'obturation 51 de la barrette 15 et dans lequel est disposé un électroaimant 19.There figure 7 shows the cut-off mechanism 3 in the assembled version, in the form of a parallelepipedic box from which the blanking plate 51 of the strip 15 extends laterally and in which an electromagnet 19 is placed.

En se référant à la figure 8 on voit le boîtier 17 comprenant un fond 171 et des parois latérales 172, le tout étant refermé par un couvercle 173 qui est positionné sur la face opposée au fond. Le fond 171 et le couvercle 173 comportent tous deux un trou formant support pour un axe de rotation 151 porteur de la barrette 15.By referring to the figure 8 we see the case 17 comprising a bottom 171 and side walls 172, the whole being closed by a cover 173 which is positioned on the face opposite the bottom. The bottom 171 and the cover 173 both have a hole forming a support for a rotation axis 151 carrying the bar 15.

L'axe de rotation 151 de la barrette a une forme cylindrique de révolution et s'étend à l'intérieur du boîtier 17 jusqu'à traverser à la fois la paroi de fond 171 et le couvercle 173. Il présente un diamètre qui correspond à celui des trous qui sont pratiqués dans ces deux parois. Il comporte par ailleurs entre ses deux extrémités une forme cylindrique d'un diamètre supérieur 152 pour s'adapter au diamètre intérieur d'un second aimant permanent cylindrique 154 comme cela sera expliqué plus loin. A une des extrémités de ce cylindre épaissi 152 se trouve un moyen d'accrochage 153 de la plaque d'obturation 51 qui permet d'entraîner celle-ci par un actionnement de l'axe de rotation 151.The axis of rotation 151 of the strip has a cylindrical shape of revolution and extends inside the case 17 until it passes through both the bottom wall 171 and the cover 173. It has a diameter which corresponds to that of the holes which are made in these two walls. It also comprises between its two ends a cylindrical shape of a larger diameter 152 to adapt to the internal diameter of a second cylindrical permanent magnet 154 as will be explained later. At one of the ends of this thickened cylinder 152 is a means 153 for hooking the closing plate 51 which makes it possible to drive the latter by actuating the axis of rotation 151.

Le second aimant permanent cylindrique 154 a une forme cylindrique creuse dont le diamètre intérieur est égal à celui, extérieur, du cylindre épaissi 152 de la barrette 15. De la sorte le cylindre épaissi 152 est inséré, à force, dans le second aimant permanent 154 et est solidarisé avec lui en rotation. Toute rotation de l'aimant permanent entraîne une rotation de l'axe de rotation 151 et un déplacement circulaire de la plaque d'obturation 51. Le diamètre extérieur du second aimant permanent 154 est tel qu'il peut s'insérer, sans contact, à l'intérieur de la carcasse métallique 18 qui assure avec la bobine d'induction 191 la mise en rotation de ce second aimant permanent 154 et, in fine, de la barrette 15.The second cylindrical permanent magnet 154 has a hollow cylindrical shape whose internal diameter is equal to that, external, of the thickened cylinder 152 of the bar 15. In this way the thickened cylinder 152 is inserted, by force, into the second permanent magnet 154 and is integral with it in rotation. Any rotation of the permanent magnet causes a rotation of the axis of rotation 151 and a circular displacement of the shutter plate 51. The external diameter of the second permanent magnet 154 is such that it can be inserted, without contact, inside the metal carcass 18 which ensures with the induction coil 191 the rotation of this second permanent magnet 154 and, ultimately, of the bar 15.

La carcasse métallique 18 est réalisée en un matériau ferromagnétique et a une forme en U comprenant une branche inférieure sur laquelle est enroulée la bobine d'induction 191, comme dans le premier mode de réalisation, et deux montants latéraux 182 parallèles aux parois latérales 172 du boîtier 17. La partie supérieure de ces montants latéraux, qui se sont face, est ici creusée de façon à former entre eux une forme cylindrique creuse 184, orientée longitudinalement. Cette forme cylindrique creuse 184 a un diamètre légèrement supérieur à celui, extérieur, du second aimant permanent 154 de façon que ce dernier puisse se mouvoir librement en rotation à l'intérieur de cette forme cylindrique creuse, sous l'action d'un courant parcourant la bobine d'induction 191. Du fait de la forme cylindrique de l'aimant et de la carcasse, l'entrefer entre eux reste constant au cours de la rotation de l'aimant permanent.The metal carcass 18 is made of a ferromagnetic material and has a U-shape comprising a lower branch on which the induction coil 191 is wound, as in the first embodiment, and two side uprights 182 parallel to the side walls 172 of the housing 17. The upper part of these side uprights, which face each other, is here hollowed out so as to form between them a hollow cylindrical shape 184, oriented longitudinally. This hollow cylindrical shape 184 has a diameter slightly greater than that, outside, of the second permanent magnet 154 so that the latter can move freely in rotation inside this hollow cylindrical shape, under the action of a current traversing the induction coil 191. Due to the cylindrical shape of the magnet and the carcass, the air gap between them remains constant during the rotation of the permanent magnet.

Le second aimant permanent 154 présente deux pôles magnétiques qui sont situés de part et d'autre de son axe de révolution, de sorte qu'en l'absence de courant dans la bobine ils viennent, chacun, se placer en vis-à-vis d'un des montants latéraux 182 au niveau du centre de leur forme cylindrique creuse 184. Et, dans cette position, la barrette 15 est dans la position de code.The second permanent magnet 154 has two magnetic poles which are located on either side of its axis of revolution, so that in the absence of current in the coil they each come to be placed opposite one of the side uprights 182 at the level of the center of their hollow cylindrical shape 184. And, in this position, the bar 15 is in the code position.

Lorsqu'un courant est envoyé dans les spires de la bobine d'induction 191 le champ magnétique créé entre les deux montants latéraux 182 repousse les pôles magnétiques de l'aimant permanent 154 et génère une rotation du second aimant permanent 154. Cette rotation engendre un déplacement circulaire de la barrette 15 qui vient se positionner dans la position de route.When a current is sent through the turns of the induction coil 191, the magnetic field created between the two side uprights 182 pushes back the magnetic poles of the permanent magnet 154 and generates a rotation of the second permanent magnet 154. This rotation generates a circular displacement of the bar 15 which is positioned in the road position.

Enfin, pour définir avec précision les positions code et route, deux butées en rotation 174 et 174b de forme parallélépipédique, s'étendent longitudinalement à partir du couvercle 173. Une face, pour chacune d'elle, est alignée avec le centre du trou formant support de l'axe de rotation 151. Par ailleurs l'axe de rotation 151 porte à son extrémité qui traverse le couvercle 173, un cylindre de butée 155 qui s'emboite sur l'axe de rotation et duquel s'étend radialement un doigt de butée 156, de forme également parallélépipédique. Le cylindre de butée comporte en son centre une forme cylindrique creuse dont le diamètre est sensiblement égal à celui de l'axe de rotation 151, dans sa portion non épaissie, de sorte qu'il peut être emmanché en force sur cet axe de rotation. Quant au doigt de butée 156, il s'étend radialement de façon à pouvoir venir en contact avec les faces des butées 174 et 174b qui sont alignées avec le centre du trou de support de l'axe de rotation. Le doigt de butée 156 peut ainsi se mouvoir entre deux positions extrêmes, définies par les butées 174 et 174b. Dans une première position qui correspond à la position code, le doigt de butée est en appui sur une première butée 174, du fait d'une absence de courant dans la bobine d'induction et consécutivement d'une attraction des pôles du second aimant permanent 154 par le métal ferromagnétique des montants latéraux 182. Dans une seconde position, qui correspond à la position route, le doigt de butée est en appui contre la seconde butée 174b, du fait des forces électromagnétiques engendrées entre les montants latéraux de la carcasse 18 par le passage d'un courant dans la bobine d'induction.Finally, to precisely define the code and road positions, two rotational stops 174 and 174b of parallelepipedal shape extend longitudinally from the cover 173. One face, for each of them, is aligned with the center of the hole forming support of the axis of rotation 151. Furthermore the axis of rotation 151 carries at its end which passes through the cover 173, a stop cylinder 155 which fits on the axis of rotation and from which extends radially a finger stop 156, also of parallelepiped shape. The stop cylinder has at its center a hollow cylindrical shape whose diameter is substantially equal to that of the axis of rotation 151, in its non-thickened portion, so that it can be force-fitted onto this axis of rotation. As for the stop finger 156, it extends radially so as to be able to come into contact with the faces of the stops 174 and 174b which are aligned with the center of the rotation axis support hole. The stop finger 156 can thus move between two extreme positions, defined by the stops 174 and 174b. In a first position which corresponds to the code position, the stop finger rests on a first stop 174, due to an absence of current in the induction coil and consecutively to an attraction of the poles of the second permanent magnet 154 by the ferromagnetic metal of the side uprights 182. In a second position, which corresponds to the road position, the stop finger bears against the second stop 174b, due to the electromagnetic forces generated between the side uprights of the carcass 18 by the passage of a current in the induction coil.

On peut noter que dans la position de repos, l'axe reliant les pôles du second aimant permanent 154 n'est pas strictement aligné avec la direction transversale de la forme creuse 184, pour que, lorsqu'on envoie un courant dans la bobine 191, l'action des forces électromagnétiques génère toujours une rotation de l'axe 15 en direction de la position route. Un alignement parfait de cet axe aurait en fait correspondu à une position instable lorsqu'un courant est appliqué à la bobine d'induction, et à partir de laquelle la barrette 15 serait susceptible de se déplacer en rotation, aléatoirement dans un sens ou dans l'autre. Enfin la figure 9 montre une variante du deuxième mode de réalisation qui fait le pendant de la variante du premier mode, avec la présence d'un ressort de rappel 175 monté à force sur l'axe de rotation 151. Ce ressort de rappel est positionné sur l'extrémité de l'axe de rotation, dans sa partie non épaissie, qui fait face au fond du boîtier 17. Comme précédemment ce ressort est un ressort spiral qui agit en écartement et qui, pour cela, prend appui sur deux becquets (non représentés) positionnés respectivement sur le fond du boîtier 17 et sur la plaque d'obturation 51 de la barrette. Ce ressort de rappel a pour objet, comme dans le premier mode de réalisation, de faciliter le retour vers la position de code et d'augmenter la vitesse de déplacement de la barrette vers cette position lorsque le courant dans la bobine est coupé.It may be noted that in the rest position, the axis connecting the poles of the second permanent magnet 154 is not strictly aligned with the transverse direction of the hollow shape 184, so that when a current is sent in the coil 191 , the action of the electromagnetic forces always generates a rotation of the axis 15 in the direction of the road position. A perfect alignment of this axis would in fact have corresponded to an unstable position when a current is applied to the induction coil, and from which the bar 15 would be likely to move in rotation, randomly in one direction or in the other direction. 'other. Finally the figure 9 shows a variant of the second embodiment which is the counterpart of the variant of the first mode, with the presence of a return spring 175 force-fitted on the axis of rotation 151. This return spring is positioned on the end of the axis of rotation, in its non-thickened part, which faces the bottom of the case 17. As before, this spring is a spiral spring which acts apart and which, for this, rests on two spoilers (not shown) positioned respectively on the bottom of the case 17 and on the blanking plate 51 of the bar. The purpose of this return spring, as in the first embodiment, is to facilitate the return to the code position and to increase the speed of movement of the bar to this position when the current in the coil is cut off.

On va maintenant décrire le fonctionnement du mécanisme de coupure selon le premier ou le second mode de réalisation, dans la version nominale. Le fonctionnement dans la variante est similaire, si ce n'est que le ressort améliore le retour vers la position de code. En l'absence de courant traversant la bobine d'induction 91 ou 191, le noyau ferromagnétique 92 ou 182 de celle-ci subit une attraction de la part de l'aimant permanent 54 ou 154. Comme ce noyau est fixe, c'est l'aimant qui bouge.We will now describe the operation of the cut-off mechanism according to the first or the second embodiment, in the nominal version. The operation in the variant is similar, except that the spring improves the return to the code position. In the absence of current passing through the induction coil 91 or 191, the ferromagnetic core 92 or 182 of the latter undergoes an attraction from the permanent magnet 54 or 154. As this core is fixed, it is the moving magnet.

Dans le premier mode le premier aimant permanent 54 vient se coller contre ce noyau, faisant ainsi tourner le support de plaque 52 et dans le second mode, le second aimant permanent 154 tourne sur lui-même pour aligner ses pôles avec les montant latéraux ferromagnétiques 182. Dans les deux modes le déplacement ou la rotation de l'aimant permanent entraîne une rotation de l'élément qui supporte la plaque d'obturation 51 (support de plaque 52 ou axe de rotation 151) et amène la barrette dans une position où elle est en butée. Cette butée est constituée par le contact du premier aimant 54 avec le noyau ferromagnétique dans le premier mode et par le contact du doigt de butée 156 contre une butée 174 du couvercle dans le second mode. Le contact sur une butée assure un positionnement précis de la plaque d'obturation et donc de la hauteur du faisceau dans la position de code. Par ailleurs, le fait que cette position est obtenue en absence de courant dans la bobine en fait une position de repos dans laquelle vient se positionner la plaque d'obturation en cas de panne et donc, le passage automatique en position de code dans ce cas.In the first mode the first permanent magnet 54 comes to stick against this core, thus rotating the plate support 52 and in the second mode, the second permanent magnet 154 rotates on itself to align its poles with the ferromagnetic side uprights 182 In both modes the displacement or rotation of the magnet permanent causes rotation of the element which supports the blanking plate 51 (plate support 52 or axis of rotation 151) and brings the bar into a position where it is in abutment. This abutment is constituted by the contact of the first magnet 54 with the ferromagnetic core in the first mode and by the contact of the abutment finger 156 against an abutment 174 of the cover in the second mode. The contact on a stop ensures precise positioning of the blanking plate and therefore of the height of the beam in the code position. Furthermore, the fact that this position is obtained in the absence of current in the coil makes it a rest position in which the blanking plate is positioned in the event of a breakdown and therefore the automatic switch to code position in this case. .

L'actionnement de la plaque d'obturation s'effectue dans les deux modes par l'envoi d'un courant dans la bobine d'induction 91 ou 191 qui crée un pôle de même signe en face du pôle de l'aimant permanent qui fait face au noyau ferromagnétique 92 ou aux montants latéraux 182. Ceci génère une répulsion du premier aimant permanent 54 dans le premier mode ou une mise en rotation du second aimant permanent 154 dans le second mode, et donc une rotation de la barrette et de sa plaque d'obturation 51 qui s'écarte alors du faisceau lumineux.The shutter plate is actuated in both modes by sending a current through the induction coil 91 or 191 which creates a pole of the same sign opposite the pole of the permanent magnet which faces the ferromagnetic core 92 or the side uprights 182. This generates a repulsion of the first permanent magnet 54 in the first mode or a rotation of the second permanent magnet 154 in the second mode, and therefore a rotation of the bar and its shutter plate 51 which then moves away from the light beam.
