    The field of the present invention is that of the light projectors and, more particularly, that of projectors for a motor vehicle.
    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.
    It is known to use a bar (or blade) cutoff for various phases of occultation of the light beam. The cut-off 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 the dipped headlamps, called the code position, so as not to dazzle the drivers traveling in the opposite direction, or to that of the high beam, called the road position, in which it There is no occultation.
    The devices of the prior art which control the position of the cut-off bar are generally constituted by an actuating motor associated with a sensor of the position of the cut-off bar or a stop which defines the rest position of the bar cut. For safety reasons, this rest position is associated with the code position, in order to avoid glare of the drivers coming in the opposite direction in the event of a failure of the device for actuating the bar. The recall on the stop position or on the extreme position is generally ensured by a spring.
    For the production of actuating motors, it is known to use an electromagnet which exerts, against a return spring, a force of attraction on a moving element connected to the cut-off bar. It also includes a metal carcass that forms a cradle for the electromagnet and that ensures its magnetic closure. The electromagnet includes an induction coil formed by turns that are energized with electric current to drive the motor, and a ferromagnetic core that is placed at the center of the coil. This core is fixed longitudinally in the coil and serves to serve as a point of attraction for the moving element when the coil is energized.
    One of the problems encountered with such an electromagnet is that the ferromagnetic core, even if it is made of iron or mild steel, magnetizes somewhat during the passage of the current and that it retains a remanent magnetism after the power failure. There is then a sticking phenomenon of the moving equipment for a time which, even if it is very short, remains incompatible reaction times which are required for the rotation of a cutoff bar of a cutoff mechanism .
    Solutions have been proposed, such as the introduction of a non-ferromagnetic material, for example copper, between the core of the electromagnet and the moving equipment, or a provision which tends to increase the return torque on this mobile crew. This may be, for this, an increase in the return force of the spring or an increase of the lever arm by which the spring acts. These solutions have the disadvantage of either being relatively expensive (copper case), or to require a larger electromagnet, which is not desirable both in terms of price than congestion.
    The present invention therefore aims to provide a control mechanism of a cutoff bar which does not have the disadvantages of the prior art and in particular which, while remaining low cost, is not sensitive to the phenomenon of magnetic remanence and, therefore, does not exhibit bonding of the moving equipment at power failure. For this purpose, the subject of the invention is a cutting mechanism for a motor vehicle headlamp, said mechanism comprising a mobile assembly comprising a cut-off bar and a moving equipment carrying the cut-off bar, the cut-off bar being configured so as to be able to close more or less a light beam so as to change the optical operating mode of said projector, said mechanism further comprising an actuating motor of said moving element, the actuating motor comprising an electromagnet comprising an induction coil associated with a core fixed ferromagnetic fixed at its center and a metal carcass surrounding said induction coil, said movable element being movable under the action of said electromagnet, against at least one return spring, between a first position in the vicinity and a second remote position via a first air gap of said ferromagnetic core.
    According to the invention, said moving element is configured to create a break in the continuity of a magnetic circuit formed by said ferromagnetic core, said metal carcass and said moving element, when it comes close to said ferromagnetic core (without contact with said ferromagnetic core). ferromagnetic core) in said first position.
    This break prevents the ferromagnetic parts constituting the control motor from being magnetized during activation of the actuating motor and do not stick, even temporarily to each other when stopping this activation.
    Preferably, said break in continuity forms a second gap in said magnetic circuit. More preferably, said magnetic circuit generates in said second air gap a force of attraction on the moving element which tends to keep it close to the ferromagnetic core (in said first position). This additional force makes it possible to size the main attraction force to a smaller value.
    Advantageously, the mobile equipment comprises a ferromagnetic plate formed by an upper plate and a lower plate extending on either side of an axis of rotation, and said lower plate is close to a branch of the metal carcass, to create said second air gap, during a rotation bringing the upper plate close to the ferromagnetic core in the first position of the moving equipment.
    In a particular embodiment, said metal carcass comprises at least one attraction element configured to facilitate the attraction of the moving element in order to attract it in said first position.
    Advantageously, the attraction element is arranged on one side of a central branch of the metal casing at the lower end of the lower plate of the ferromagnetic plate, being bent towards said lower plate, and being arranged laterally so as not to come into contact with the lower plate during the rotation of the moving equipment. Preferably, the attraction element represents a partially cut-out lamella in the central branch of the metal carcass and curved towards said lower plate in the second position of the moving equipment.
    In a particular embodiment, the metal carcass comprises at least one element of attraction of each of the sides of the central branch.
    Furthermore, in a preferred embodiment, the moving assembly is configured to have a load distribution for obtaining a position of equilibrium with respect to an axis of rotation of said movable assembly which is rotatable.
    Preferably, the charge distribution is generated by adding or removing material to at least one of said upper and lower plates of the ferromagnetic plate.
    By thus balancing the masses (or loads) of the moving equipment and the cut-off bar around the axis of rotation, the attraction force necessary to rotate the moving assembly can be relatively small, and can be generated. using a small electromagnet.
    Furthermore, in a preferred embodiment, the cut-off bar is connected by a first longitudinal end to the moving element, and it is provided towards a second longitudinal end, opposite this first longitudinal end, of a flexible abutment.
    Preferably, said flexible stop comprises a lamella formed longitudinally in the body of the cut-off bar. The invention also relates to a motor vehicle headlight comprising at least one cutting mechanism as described above. The invention will be better understood, and other objects, details, features and advantages thereof will appear more clearly in the following detailed explanatory description of embodiments of the invention given by way of example. purely illustrative and non-limiting, with reference to the accompanying schematic drawings. In these drawings: FIG. 1 is a perspective view of an element of a vehicle headlight comprising a cut-off mechanism; - Figures 2 and 3 are front views of the cutting mechanism of Figure 1, positioned on an armature, respectively in the road position and code; FIG. 4 is a perspective view of a cut-off mechanism according to one embodiment of the invention, in an assembled version; FIG. 5 is an exploded view showing, in perspective, the various elements constituting the cut-off mechanism of FIG. 4; - Figures 6 and 7 are schematic views of an actuating motor of the cutting mechanism, respectively in a rest position and in an activation position, according to a first embodiment; - Figures 8 and 9 are schematic views of the actuating motor of the cutoff mechanism, respectively in a rest position and in an activation position, according to a second embodiment; and FIG. 10 is a front view of one end of a cut-off bar.
    In the following description, the longitudinal or lateral references are understood with reference to the optical axis of the reflector and the terms forward or back refer to the direction in which the light beam propagates.
    Referring to Figure 1, we see the front portion of a motor vehicle headlight 10 comprising a cylindrical lens holder 1 which extends forwardly from a frame 2 of rectangular shape. This extends in a plane perpendicular to the optical axis of the beam and is cut at its center to let said beam. On this frame is fixed the cutoff mechanism whose function is to close more or less the beam depending on the traffic conditions of the vehicle. Not visible, are arranged behind this frame, a light source generating the beam and a reflector that directs the beam forward and to the lens (not shown) which is installed at the front end of the lens holder 1.
    With reference to FIGS. 2 and 3, in front view, respectively in road position and in code position, the cut-off mechanism 3 which is mounted in a low position on the armature 2 is seen. This armature 2 comprises, in lower part of its central cutout, a fixed cover 4 which partially closes this cut and in front of which can move a bar (or blade) cut 5 to modulate the shape of the beam output of the projector 10. This cutoff bar 5 is movable in rotation in a plane perpendicular to the light beam and is driven by an actuating motor 6.
    In Figure 2, corresponding to the road position, the cutoff bar 5 is retracted, that is to say that it is inclined downwards and reveals the fixed cover 4, which allows almost the the entire light beam. In FIG. 3, corresponding to the coded position, the bar is raised and it cuts the beam on a greater height than would the single fixed cover 4. After its overthrow by the lens, the beam is then directed downwards. This avoids dazzling the drivers of oncoming vehicles.
    Figures 4 and 5 show the cutting mechanism 3 according to an embodiment, respectively, in the assembled position and exploded position.
    This cutoff mechanism 3 comprises the bar (or blade) cut 5 which is rotatable about a first pin 31 attached to a fixed structure 30 connected to the frame 2. It pivots around the first pin 31, in response to a control of the actuating motor, under the action of a lever arm 42 of a moving element 40, as specified below. This mobile assembly 40 forms with the cut-off bar 5 and the means for linking them together, a moving assembly 8 which is rotatable.
    This fixed structure 30 comprises a plate 32, to which is attached an electromagnet coil 61 which is supplied, if necessary, with electric current to rotate or release the mobile assembly 8 comprising the mobile assembly 40 and the cut-off bar 5. It also comprises two supports 33, which are connected to the plate 32, and whose function is to receive an axis of rotation 41 connected to the moving element 40 which drives the cut-off bar 5. It comprises in addition, an electrical connector 34, through which the control current of the electromagnet passes.
    In the particular embodiment shown, the two supports 33 each have the shape of a V-shaped piece with two uprights which gradually move apart from one another to form a guide during the introduction of the rotation axis 41 of the moving equipment. The bottom of the V comprises a cylindrical cut-out serving as a housing for this axis of rotation 41 once it is put in place on the fixed structure 30. The diameter of this cylindrical cut is slightly greater than the spacing of the two branches in the bottom V, so as to form a retaining clipping for this axis of rotation after its introduction.
    The actuating motor 6 for actuating the breaking bar 5 comprises an electromagnet 7. This electromagnet 7 comprises, in the usual way, a coil (or induction coil) 61, which is attached to the plate 32 at its upper part and a second plate 35 at its lower part, and a ferromagnetic core 62 fixed, substantially cylindrical, which is placed in the center of this coil, along its axis of symmetry. This ferromagnetic core 62 carries at its upper end, a circular plate 63, of greater diameter than that of the core 62, which protrudes from the plate 32 and serves as a pole of attraction for the moving element 40. This ferromagnetic core 62 is positioned fixedly within the winding 61 and serves as a guide, inside the winding, electromagnetic lines of force that are generated by the passage of a current in the electromagnet of the engine 6. These lines of force serve to generate an attraction of the moving element 40 by the circular plate 63.
    The actuating motor 6 further comprises a U-shaped metal casing 64 which surrounds the coil 61 and whose object is, in the usual way, to guide the electromagnetic lines of force outside the coil. the coil 61. While the central branch 65 of the metal casing 64, formed by the bottom of the U, extends parallel to the axis of the coil 61, its lower branch 66 comes into contact with the second plate 35, level of the foot of the ferromagnetic core 62, and its upper branch 67 returns to the axis of the coil 61, in its upper part, however remaining away from the circular plate 63 of the core 62.
    Between the end (free) end 67a of the upper branch 67 of the metal frame 64 and the circular plate 63 is positioned the moving assembly 40 (Figures 6 and 7), the characteristics of which are described below. The mobile equipment 40 mainly comprises a mobile L-shaped ferromagnetic plate 43, the object of which is, on the one hand, to ensure continuity in guiding the electromagnetic lines of force, in the extension of the metal carcass. 64 and in particular in the direction of the axis of the coil 61, and secondly, to maintain an open gap in this circuit, that this ferromagnetic plate 43 is moved away or not from the fixed circular plate 63 of the ferromagnetic core of the induction coil 61. For this, one of the branches of the ferromagnetic plate 43, said upper plate 43a, is substantially aligned with the upper branch 67 of the metal casing 64, between the end end 67a of this upper branch 67 and the ferromagnetic core 62, while its other branch, said lower plate 43b, is substantially parallel to the central branch 65 of the metal casing 64. This quasi-parallelism of the two parts ies of the ferromagnetic plate 43 movable with the central and upper branches of the metal casing 64 allows to give some continuity to the magnetic circuit around the coil 61 of the electromagnet.
    The ferromagnetic plate 43 is movable in rotation and carries for this purpose, on its upper plate 43a, an axis of rotation 41, around which rotates the entire moving assembly 40. This axis of rotation 41 is located at a relatively short distance from the end (upper) of the upper plate 43a, which is located opposite the circular plate 63, so as to reduce the operating lever arm of the moving element 40 by the attraction force exerted by the ferromagnetic core 62. This short lever arm makes it possible to reduce the size of the electromagnet 7. Preferably, the axis of rotation 41 is located laterally above the coil 61, inside the extension of the cylinder formed by that -this.
    On this axis of rotation 41 is positioned a return spring 45, which is supported on the fixed structure 30 and which tends to recall the upper plate 43a of the moving assembly 40 at a distance from the circular plate 63 of the ferromagnetic core 62 when no current flows through the winding.
    Furthermore, from this axis of rotation 41 extends radially on the side of the movable plate 43, an arm 42 forming a lever for the rotation of the movable assembly 8, that is to say of the cutoff bar 5 and the moving assembly 40. For this purpose, in the embodiment shown in FIGS. 4 and 5, the cutoff bar 5 comprises a first cylindrical hole 51, in which the first post is housed. 31 which serves as a pivot to the cutoff bar 5, and a second cylindrical hole 54, in which is housed a second pin 44 which extends to the end of this arm 42, parallel to the axis of rotation 41, to serve as actuating means for said cutoff bar 5.
    Figures 6 and 7 show the relative disposition of the movable plate 43 and the metal casing 64, respectively, in the two positions P1A and P2A that can take the moving assembly 40, that is to say, a on the other hand, in a so-called rest position P2A (FIG. 6), and on the other hand in a so-called activation position P1A (FIG. 7), under the action of the passage of a current in the coil 61.
    In the rest position P2A (FIG. 6), no current flows in the coil 61 and the ferromagnetic core 62 exerts no attraction on the movable plate 43. The upper plate 43a thereof is then moved away from the circular plate 63 of the ferromagnetic core 62, under the action of the return spring 45. There is no contact between these two parts which are separated from each other by a first gap h1A. The lines of force of the magnetic circuit starting from the ferromagnetic core 62, and pass through the metal casing 64 and the upper plate 43a and close on the core 62 through the first air gap h1 A.
    In the activation position P1A (FIG. 7) where a current flows in the coil 61, the ferromagnetic core 62 attracts the upper plate 43a of the movable plate 43, which approaches said ferromagnetic core 62 against the spring of recall 45. The first gap is then reduced (h1B) but not zero. In addition, the lower plate 43b is close to the central branch 65 of the metal casing 64 to the point of creating with it a second air gap h2, without contact. In this configuration, the lines of force starting from the ferromagnetic core 62, pass through the lower branch 66 and then through the lower part of the central branch 65 of the metal casing 64; they then pass through the gap h2 to then follow the lower plate 43b and the upper plate 43a and close the circuit via the gap h1 B reduced between this upper plate 43a and the circular plate 63.
    In both cases, the magnetic circuit comprises at least one gap (h1A; h1B, h2) which opens the magnetic circuit and prevents its components from being magnetized when the winding is energized, which eliminates the risk of bonding the upper plate 43a against the circular plate 63. The mobile assembly 40 is thus movable under the action of the electromagnet 7, against the return spring 45, between a first (activation) position in the vicinity and a second position of remote rest via the first gap h1A, said ferromagnetic core 62.
    According to the invention, the mobile equipment 40 is configured to create a break in the continuity of the magnetic circuit formed by the ferromagnetic core 62, the metal casing 64 and the mobile assembly 40, when the mobile assembly 40 arrives close to said ferromagnetic core 62 in said P1A activation position.
    The so-called activation position in proximity (that is to say without contact) corresponds to a position for which there is a short gap h1B between the upper plate 43a and the circular plate 63 as shown in particular in FIG.
    Moreover, in a particular embodiment, the metal casing 64 comprises, as represented in FIGS. 8 and 9, at least one attraction element 68. This attraction element 68 corresponds to a projecting element that is configured to facilitate the attraction of the moving element 40 when the latter is brought from the rest position P2B (FIG. 8) to the activation position P1B (FIG. 9). Figures 8 and 9 are similar to Figures 6 and 7, including positions called P1B and P2B instead of P1A and P2A. The attraction element 68 is arranged on one side 64A of the central branch 65 (FIG. 5) of the metal casing 64 at the lower end 46 of the lower plate 43b of the ferromagnetic plate 43 (FIG. 8). . The attraction element 68 is a protruding element which is bent towards said lower plate 43b of the ferromagnetic plate 43, and is arranged laterally so as not to come into contact with the lower plate 43b during the rotation of the crew mobile 40. Thus formed and positioned, the attraction element 68 allows first, from the position P2B of Figure 8, when a current comes to feed the electromagnet, to participate in the attraction of the lower plate 43b, then maintain a constant air gap.
    In the embodiment shown, the salient element 68 salient represents a lamella 69 partially cut in the central branch 65 of the metal casing 64 and bent towards said lower plate 43b in the position P2B of the moving assembly 40.
    In an alternative embodiment (not shown), the metal casing 64 may comprise such an element of attraction of each of the sides 64A and 64B of the central branch 65.
    Furthermore, in a particular embodiment, said moving assembly 8 is configured to have a load distribution that makes it possible to obtain a position of equilibrium with respect to the axis of rotation 41 of the moving assembly 40.
    By thus balancing the masses of the moving element 40 and the cutoff bar 7 about this axis of rotation 41, the attractive force necessary to rotate the rotation assembly 8 may be relatively small. It is thus possible to use an induction coil 61 of small size, which provides advantages in terms of cost and space in particular.
    In a preferred embodiment, this charge distribution is generated by adding and / or removing material to at least one of said upper 43a and lower 43b plates of the ferromagnetic plate 43 and / or to the cutoff bar 5 The load distribution can be obtained by an adaptation of the thickness of one of the aforementioned parts or by any other usual means.
    Moreover, in a particular embodiment, shown in particular in Figures 4, 5 and 10, the cutoff bar 5 is provided with a stop 55 flexible at a longitudinal end 53, opposite the longitudinal end 52 to which the cutoff bar 5 is linked to the moving equipment.
    As represented in FIG. 10, the stop 55 comprises a strip 56 which is formed by a longitudinal cutout 58 (according to the longitudinal extension of the cut-off bar 5) made in the body 57 of the cut-off strip 5 near its edge. upper edge.
    This slat 56 thus formed is flexible in the direction illustrated by an arrow E in FIG. 10. The slat 56 is provided with a bead 59 projecting to come into contact with a stop 60 (FIG. yoke and secured to the frame 2, when the moving equipment returns to the rest position.
    The flexible strip 56 makes it possible to reduce the vibrations generated in the breaking bar 5 when it comes into contact with the stop 60. The stop 55 thus makes it possible to reduce the noise when the moving equipment returns to the rest position.
    We will now describe the operation of the cutoff mechanism 3 as described above. The moving element 40, in its rest position, is remote from the ferromagnetic core 62 under the action of the return spring 45 and leaves a gap h1A (FIGS. 6 and 8) between its upper plate 43a and the circular plate 63 of this core. This gap is chosen from a relatively small dimension so that the upper plate 43a can be attracted to the ferromagnetic core 62 by virtue of a current of low intensity in the coil 61. The coil 61 of the electromagnet 7 can thus be chosen from low dimension. At the same time, the lower plate 43b is relatively distant from the metal casing 64.
    When a current is sent in the coil 61 to trigger the passage in road position for the projector, the upper plate 43a is attracted to the circular plate 63. The two pieces approach one another and the movable member 40 is shaped so that the lower plate 43b does not come into contact with the metal casing 64 forming the second gap h2. Thus, the magnetic circuit generated by the electromagnet does not close. This prevents magnetization of the movable plate 43 and remanence which would produce a sticking effect of the movable plate 43 on the circular plate 63.
    Moreover, the space left free between the lower plate 43b and the central branch of the metal casing 64 is calibrated so as to form a relatively small air gap h2 between these two parts. As the magnetic circuit, in the activation position of the cutting mechanism, passes through the lower plate and the central branch, an attraction is created between these two parts. This force is added to that of attraction of the upper plate 43a to the circular plate 63 and ensures a permanence of the position between the movable plate and the ferromagnetic core. This additional force makes it possible, for example, to take into account the jolts due to jolts of the road, which could separate these two parts. This additional force of attraction is increased by the position and the action of the attraction element 68. It is then not necessary to over-size the main attraction force related to the first air gap h1A to take account of these hazards.
    The double attraction created by the two gaps makes it possible to reduce the size of the coil 61 and overall of all the electromagnet 7, and therefore of the actuating motor 6 of the cutoff bar 5.
    Finally, note that the mobile assembly 40 is in the rest position or in the activation position, that the magnetic circuit passes through the axis of rotation 41. In one case, it runs along the upper branch of the carcass to join the upper plate 43a at this axis of rotation. In the other case, it circulates on the lower part of the central branch of the metal casing 64 and then on the movable plate 43 and thus passes through the axis of rotation 41. This situation gives complete freedom to position the axis of rotation laterally. rotation 41, as long as it remains in this magnetic circuit. It can thus be placed as close to the circular plate 63, and therefore greatly reduce the lever arm which actuates the rotation of the moving assembly 40. In a preferred embodiment (not shown), the axis of rotation 41 is positioned laterally above the coil 61, secantly with the cylinder extending it upwardly or downwardly.
