    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a light device for a motor vehicle.
    It finds a particular but not limiting application in lighting and / or signaling devices, such as motor vehicle headlights.
    TECHNOLOGICAL BACKGROUND OF THE INVENTION
    A light device for a motor vehicle comprises, in a manner known to those skilled in the art, a support and at least one light module.
    To adjust the positioning of the light module on the support, plastic capsules fixed to said light module are used. Each capsule cooperates with a ball head screw forcefully inserted into said capsule. The light module thus comprises a fixed point (ball joint connection) and two screws for forcing a rotation of said light module in a vertical direction and in a horizontal direction. This makes it possible to adjust a light beam produced by said light module.
    A drawback of this state of the art is linked to the change in the size of the light modules. Indeed, when the light device comprises a plurality of light modules, these light modules are smaller and the screws and capsules are then almost as large as the light modules themselves and can therefore no longer be used. In addition, the capsule may break if its size is reduced.
    In this context, the present invention aims to solve the aforementioned drawback.
    GENERAL DESCRIPTION OF THE INVENTION
    To this end, the invention proposes a light device for a motor vehicle, said light device for a motor vehicle comprising:
    - a support ;
    - At least one light module, said light module being pivotally mounted around at least one axis on the support by means of at least one pivot connection between the light module and the support, said pivot connection comprising an elastically deformable element arranged to allow the light module to pivot relative to the support around said axis;
    - At least one light module adjustment means arranged to allow the light module to pivot relative to the support around said axis when the adjustment means is actuated;
    - a constraint means arranged to maintain the light module in position relative to the support in the absence of actuation of the adjustment means.
    Thus, as will be seen in detail below, no more capsules are used. Furthermore, the elastically deformable element facilitates the positioning of the light device at the pivot connection. Once the position of the light device has been adjusted, the constraint means keeps the light module in this position. The constraint means is adapted to absorb vibrations at the pivot connection and prevents the latter from breaking.

    DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    Identical elements, by structure or by function, appearing in different figures keep, unless otherwise specified, the same references.
    The light device 10 for a motor vehicle according to the invention is described with reference to Figures 1 to 10.
    By motor vehicle is meant any type of motor vehicle.
    In a nonlimiting embodiment taken in the following description, the light device 10 is a lighting and / or signaling device. In a nonlimiting variant, the lighting and / or signaling device is a motor vehicle headlamp.
    As illustrated in Figures 1 or 5, the light device 10 comprises
    - a support 3;
    - at least one light module 5;
    - At least one pivot link 7A adapted to mount the light module 5 on the support 3 pivotally;
    - at least one adjustment means 7B, 7C; and
    - a means of restraint 15.
    The pivot link 7A allows the light module 5 to rotate in the vertical Y and horizontal Z directions.
    Said at least one adjustment means 7B, 7C allows the light module 5 to pivot relative to the support 3 about an axis 8 when said at least one adjustment means 7B, 7C is actuated.
    In a nonlimiting embodiment, the light device 1 comprises two adjustment means 7B and 7C. The adjustment means 7B and the adjustment means 7C allow respectively a horizontal and vertical adjustment of the light module 5 relative to the support 3.
    The constraint means 15 keeps the light module 5 in position relative to the support 3, once the horizontal adjustment and the vertical adjustment of the light module 5 have been carried out. This maintenance is carried out in the absence of actuation of the adjustment means 7B, 7C.
    In a nonlimiting embodiment, the light device 10 comprises a plurality of light modules 5 adapted to be mounted on a support 3 each by means of a pivot link 7A and at least one adjustment means 7B, 7C.
    In the nonlimiting example illustrated in FIGS. 1 and 5, the light device 10 comprises three light modules 5 adapted to be mounted on a support 3 each via a pivot link 7A and two adjustment means 7B, 7C.
    In a nonlimiting embodiment illustrated in FIGS. 1 and 5, the light device 10 further comprises a light module 5 ′ adapted to serve as a reference module for positioning the other light modules 5 in the light device 10. In this In this case, the reference light module has three pivot links 7A which are adjusted in the same way (at the same level). These three pivotal connections thus form three fixed points. This 5 ’reference module is positioned along the axis of the road as a function of the photometric function determined.
    Thus, the light segment 22 produced by this reference light module 5 ′ serves as a reference light segment for the adjustment of the other light segments 22 (illustrated in FIG. 3, 7 or 8) of the other light modules 5. The other light segments 22 can thus be adjusted vertically and horizontally so as to be aligned on the reference light segment and so as to create a segmented light beam composed of several light segments 22, selectively activatable.
    Thanks to the pivot link 7A and the adjustment means 7B, 7C, each light module 5 can be adjusted relative to the reference module 5 ’independently of the other light modules 5.
    The light device 1 is illustrated according to a first nonlimiting embodiment illustrated in FIGS. 1 to 4 and according to a second nonlimiting embodiment illustrated in FIGS. 5 to 8.
    The pivot link 7A illustrated in FIGS. 9 and 10 applies to these two nonlimiting embodiments.
    According to the first non-limiting embodiment of the light device 1:
    - The light module (s) 5 comprises a constraint means 15 illustrated in FIGS. 2 and 3 which is distinct from said at least one adjustment means 7B, 7C, namely it is not integrated into said at least one adjustment means 7B, 7C.
    - Ie (s) light module (s) 5 comprises two adjustment means 7B, 7C according to a first non-limiting embodiment illustrated in Figure 4;
    According to the second nonlimiting embodiment of the light device 1:
    - The light module (s) 5 comprises a constraint means 15 which is part of said at least one adjustment means 7B, 7C;
    - The light module (s) 5 comprises two adjustment means 7B, 7C:
    - According to a first nonlimiting variant illustrated in FIG. 7 in which the adjustment means 7B, 7C are integral with the support 3; or
    - according to a second nonlimiting variant illustrated in FIG. 8 in which the adjustment means 7B, 7C are integral with the light module 5.
    The various elements of the light device 10 are described in detail below according to the various nonlimiting embodiments.
    o Light module
    As illustrated in FIGS. 3, 8 and 9, a light module 5 comprises:
    - A base 50 adapted to allow the fixing of the light module 5 on the support 3;
    - an optical means 51;
    - a light source 52 comprising light emission means (not shown) and adapted to emit light rays forming a light segment 22.
    When the light device 10 comprises a plurality of light modules 5 as illustrated in FIG. 1 or FIG. 6, said light modules 5 form a matrix. The set of light segments 22 of the different light modules 5 then forms a segmented light beam also called a matrix light beam. The light segments 22 are selectively activatable, i.e. they can be generated independently of each other.
    In a nonlimiting example, the segmented light beam of the light device 10 is adapted to provide a photometric function called "high beam" to produce a high beam. In another nonlimiting example, the segmented light beam of the light device 10 is adapted to provide a photometric function called "low beam" to produce, for example, a low beam.
    In a nonlimiting embodiment, the optical means 51 is:
    - a reflector; and or
    - a lens.
    The optical means 51 cooperate with the light source 52 described below to form the light segment 22.
    In the nonlimiting example illustrated in FIGS. 3, 8 and 9, the optical means 51 is a reflector secured to the base 50 of the light module 5.
    In a nonlimiting embodiment illustrated in FIGS. 8 and 9, the support 3 of the light device 10 comprises an opening 53 through which ίο passes through the light segment 22.
    In addition to the light emission means, the light source 52 includes an electrical connection interface (not shown). The electrical connection interface is suitable for the power supply and the control of the light emission means. The electrical connection interface is adapted to cooperate with an external electrical connector which makes it possible to send control commands to the light source 52 and to supply it.
    In a nonlimiting embodiment, the light emission means comprise at least one semiconductor emitting chip.
    In a nonlimiting variant embodiment, a semiconductor emitting chip is part of a light-emitting diode. By light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LEDs (“Light Emitting Diode”), an OLED (“Organic LED”) or an AMOLED (“Active-MatrixOrganic LED”), or a FOLED ("Flexible OLED"). Alternatively, the light emitting means may comprise a laser source associated with a wavelength conversion element, such as a photoluminescent material.
    o Support, from. disposit if read min them
    In a nonlimiting embodiment, the support 3 of the light device 10 is a housing of the light device 10.
    In another nonlimiting embodiment, the support 3 of the light device 10 is an intermediate plate on which the light module (s) 5 are fixed.
    In FIGS. 1 to 12, in a nonlimiting embodiment, each light module 5 is fixed to the support 3 by:
    - a pivot link 7A;
    - two adjustment means 7B, 7C.
    o Link.pivot
    The pivot link 7A allows the light module 5 to rotate in the vertical Y and horizontal Z directions.
    The pivot link is also called a fixed point.
    As illustrated in FIGS. 9 and 10, in a nonlimiting embodiment, the pivot link 7A comprises:
    - a threaded rod 17A;
    - a locking nut 19A; and
    - an elastically deformable element 18.
    These various elements are described in detail below.
    In a nonlimiting embodiment, the threaded rod 17A is made of steel or plastic reinforced with glass fibers. This material is inexpensive.
    The threaded rod 17A is integral with a boss 30 of the support 3. The threaded rod 17A is adapted to fit into the base 50 and thus makes it possible to connect the light module 5 to the support 3.
    In a nonlimiting embodiment, the boss 30 of the support 3 is of cylindrical shape.
    The base 50 includes a passage orifice 11A for the threaded rod 17A. This orifice 11A has a width greater than the threaded rod 17A so that there is a clearance 01 between the threaded rod 17A and the walls of said orifice 11A.
    The threaded rod 17A and the boss 30 extend along an axis 6.
    In a nonlimiting embodiment, the orifice 11A comprises a diameter of less than five millimeters.
    The locking nut 19A allows the light module 5 to be locked on the support 3. This locking nut 19A is suitable for being screwed onto the threaded rod 17A. It includes for this a complementary screw pitch to the thread of the threaded rod 17A. The tightening of the locking nut 19A is carried out so that this locking nut:
    - does not block the rotation of the light module 5 around an axis 8 called the axis of rotation. This axis of rotation 8 is perpendicular to the axis 6. The light module 5 can thus pivot around this axis of rotation 8 when it is adjusted by the adjustment means 7B, 7C (described below);
    - is in contact with the base 50, in particular with its upper face 501.
    Thus, the locking nut 19A is not fully screwed onto the threaded rod 17A so that it is possible to rotate the light module 5 around the axis of rotation 8.
    In a nonlimiting embodiment, the locking nut 19A is made of steel or of glass fiber reinforced plastic.
    The elastically deformable element 18 is disposed between the base 50 of the light module 5 and the boss 30 of the support 3. In particular, the elastically deformable element 18 is in contact with the underside 500 of the base 50.
    In FIG. 9, the elastically deformable element 18 is uniformly crushed by the light module 5. The module 5 is in a first position in which for example the light segment 22 of the light module 5 is not yet adjusted with respect to the segment light 22 of the reference module 5 'so as to obtain the desired matrix light beam.
    In FIG. 10, the light module 5 has been adjusted in a second position different from the first position. It has pivoted around the axis of rotation 8. The crushing of the elastically deformable element 18 is then no longer uniform. Part of the elastically deformable element 18 is almost completely flattened. Thus, the elastically deformable element 18 compresses all or part so as to accompany and allow the pivoting of the light module 5 around the axis of rotation 8.
    The elastically deformable element 18 is thus adapted to absorb the angular variations of the light module 5 when the position of this light module 5 is adjusted by the adjusting means (s) 7B, 7C.
    In a nonlimiting embodiment, the elastically deformable element 18 is made of rubber.
    It will be noted that the clearance 01 which exists between the threaded rod 17A and the walls of the orifice 11A makes it possible not to block the pivoting of the light module 5.
    It will be noted that in the case of a light module which serves as a reference module 5 ′, said light module comprises pivot links 7A which do not include an elastically deformable element 18. Indeed, in this case, the reference module does not pivot around the axis 8 because it is fixedly mounted on the support 3.
    o Adjustment means
    In a nonlimiting embodiment, the light module 5 comprises two adjustment means 7B, 7C.
    The adjustment means 7B is suitable for blocking the light module 5 horizontally, that is to say blocking said light module 5 in a direction Z, called horizontal or lateral direction as illustrated in FIGS. 2 and 6.
    The adjustment means 7C is adapted to block the light module 5 vertically, that is to say block said light module 5 in a direction
    Y, called vertical direction as illustrated in Figures 2 and 6.
    The adjustment means 7B, 7C are described below according to two nonlimiting embodiments 7B7C.
    First step:
    FIG. 4 illustrates a first non-limiting embodiment of the adjustment means 7B, 7C. In this embodiment, the adjustment means 7B, 7C are a threaded rod.
    The threaded rod 7B, 7C includes:
    - a thread 17B, 17C;
    - a rod head 27B, 27C;
    - a contact end 21 B, 21 C.
    The thread 17B, 17C is adapted to be screwed into the base 50 of the light module 5.
    For this purpose, the base 50 has two threads adapted to receive the threads 17A and 17C respectively.
    The rod head 27B, 27C is adapted to be in contact with the light module 5, and the contact end 21 B, 21C of the threaded rod is adapted to be in contact with the support 3, in particular to be supported on said support 3. Depending on the degree of screwing of the threaded rod 7B, 7C in the base 50, the position of the light module 5 is adjusted relative to this support 3. In fact, during screwing, the rod head 27B, 27C pushes on the base 50 of the light module 5 (in particular on its upper face 501) which moves respectively horizontally or vertically and pivots around the axis of rotation 8 thanks to the pivot link 7A.
    In a nonlimiting embodiment, the contact end 21 B, 21C has no sharp edges. This allows to have a smooth contact between the contact end 21 B, 21C and the support 3. This avoids having a stress point on the support 3. The threaded rod 17B, 17C is not likely to get block in the support 3 and thus does not risk breaking.
    In this first embodiment illustrated in FIGS. 1 to 3, the adjustment means 7B, 7C do not include constraint means 15. Thus the constraint means 15 and the adjustment means 7B, 7C are distinct.
    In the embodiment of the light device 1 of FIGS. 1 to 4, the constraint means 15 is arranged on one side of the support 3 opposite the pivot link 7.
    In a nonlimiting embodiment, the constraint means 15 is a spring, in particular a leaf spring. This leaf spring is in contact with the light module 5; it exerts a pressure force F on the light module 5, in particular on the upper face 501 of its base 50 as illustrated in FIG. 3. The leaf spring 15 makes it possible to absorb the movements of the pivot link 7A. It thus prevents the pivot link 7A from vibrating or breaking.
    Second. mode.r.é.ahsation .:
    Figures 5 to 8 illustrate a second embodiment of the adjustment means 7B, 7C. In this second embodiment, the constraint means 15 is integrated with the adjustment means 7B, 7C.
    In FIGS. 7 and 8, in a nonlimiting embodiment, the constraint means 15 is a spring disposed between the light module 5 and the support 3. This spring 15 acts in compression, that is to say that it exerts a force F on the light module 5 and on the support 3.
    First .variant _d_e real isation _d_u second .mode _d_e Réala_ti_qn:
    FIG. 7 illustrates a first alternative embodiment of the second embodiment. In this first variant, the adjustment means 7B, 7C is integral with the support 3.
    The adjustment means 7B, 7C comprises a threaded rod 17B, 17C and a screw pitch 14B, 14C. The thread 14B, 14C is part of the support 3 and the threaded rod 17B, 17C is screwed into said thread 14B, 14C so that it is integral with this support 3.
    The threaded rod 17B, 17C comprises an end 37B, 37C adapted to cooperate with a screwdriver head.
    The threaded rod 17B, 17C is locked on the light module 5 by a locking nut 29B, 29C which is in contact with the base 50.
    In a nonlimiting embodiment, the surface of the locking nut 29B, 29C which is in contact with the base 50 is without sharp edges. This allows variations in angle to be absorbed when the light module 5 is adjusted horizontally or vertically.
    The mounting of the light module 5 on the support 3 via the adjustment means 7B, 7C and the pivot link 7A is carried out as follows.
    In a first step, the threaded rod 17B, 17C is screwed into the support 3. It cooperates with a screw thread 14B, 14C of the said support 3. The spring 15 is then placed around the threaded rod 17B, 17C so that the the axis of the spring 15 coincides with the axis of the threaded rod 17B, 17C. The elastically deformable element 18 is arranged around the threaded rod 17A of the pivot link 7A and rests on the boss 30 of the support 3.
    In a second step, the threaded rod 17B, 17C is inserted into the orifice 11 B, 11C of the base 50 of the light module 5. The spring 15 is thus sandwiched between the base 50 of the light module 5 and the support 3. It will be noted that in a nonlimiting embodiment, the orifice 11B, 11C comprises smooth walls. The diameter of this orifice 11B, 11C is greater than the diameter of the threaded rod 17B, 17C in order to leave a clearance 02 for the passage of the threaded rod 17B, 17C. The clearance 02 allows the angle variations to be absorbed when the light module 5 is adjusted horizontally or vertically.
    At the same time, the threaded rod 17A of the pivot link 7A is inserted into the hole 11A in the base 50 provided for this purpose.
    In a third step, the locking nut 29B, 29C is screwed onto the threaded rod 17B, 17C to block said threaded rod on the base 50 and therefore on the light module 5. The locking nut 29B, 29C comes to press on the base 50 in particular on its upper face 501. It will be noted that the base 50 of the light module 5 is blocked between the spring 15 and the nut 29B, 29C.
    In a fourth step, the nut 19A is screwed onto the rod 17A of the pivot link 7A.
    In a fifth step, in order to adjust the light module 5 respectively to the horizontal, to the vertical, the screwing of the threaded rod 17B, 17C is adjusted by means of its end 37B, 37C (via a screwdriver) which brings the light module 5 of the support 3. The light module 5 pivots relative to the support 3 around the axis 8 seen previously. This approximation (which corresponds to pivoting) compresses the spring 15 associated with each threaded rod 17B, 17C. The elastically deformable element 18 and also put in compression due to the pivoting of the light module 5. The clearance 01 makes it possible to absorb variations in angle when the light module 5 pivots.
    When the threaded rod 17B, 17C is no longer in motion (ie it is no longer actuated), the spring 15 which is in compression presses on the support 3 and on the base 50 of the light module 5 so that it maintains said light module 5 in position relative to support 3.
    In addition, the spring 15 prevents the threaded rod 17B, 17C from unscrewing. Finally, the spring 15 makes it possible to absorb the vibrations which can occur on said threaded rod 17B, 17C, in particular when the motor vehicle is traveling.
    Of course, in another nonlimiting embodiment, the mounting can start with the insertion of the threaded rod 17B, 17C into the orifice 11B, 11C of the base 50 of the light module 5.
    Second variant of realization of the second embodiment:
    FIG. 8 illustrates a second alternative embodiment of the second embodiment. In this second variant, the adjustment means 7B, 7C is integral with the light module 5.
    The adjustment means 7B, 7C comprises a threaded rod 17B, 17C and a nut 19B, 19C.
    The nut of 19B, 19C is adapted to be in contact with the support 3. It makes it possible to adjust the setting of the light module 5.
    In a nonlimiting embodiment, the surface of the nut of 19B, 19C has no sharp edges. This allows variations in angle to be absorbed when the light module 5 is adjusted horizontally or vertically.
    The threaded rod 17B, 17C includes:
    - A head 47B, 47C which is adapted to cooperate with the base 50 of the light module 5 and;
    - one end 37B, 37C which and adapted to pass through the support 3.
    The threaded rod 17B, 17C is secured to the light module 5 by means of a locking nut 31 B, 31 C.
    The mounting of the light module 5 on the support 3 via the adjustment means 7B, 7C and the pivot link 7A is carried out as follows.
    In a first step, the threaded rod 17B, 17C is screwed into the base 50 of the light module 5 so that its head 47B, 47C rests on the base 50, in particular its outer face 501. It cooperates with a thread 26B , 26C of the base 50. Then the locking nut 31 B, 31C is screwed on the opposite face 500 of the base 50 to block said threaded rod on the base 50 and therefore on the light module 5. The spring 15 is then disposed around the threaded rod 17B, 17C so that the axis of the spring 15 coincides with the axis of the threaded rod 17B, 17C. The elastically deformable element 18 is arranged around the threaded rod 17A of the pivot link 7A and rests on the boss 30 of the support 3.
    In a second step, the threaded rod 17B, 17C is introduced into an orifice 24B, 24C of the support 3. The diameter of this orifice is greater than the diameter of the threaded rod 17B, 17C in order to leave a clearance 03 for the passage of the threaded rod 17B, 17C. Note that in a nonlimiting embodiment, the orifice 24B, 24C comprises smooth walls.
    The clearance 03 makes it possible to absorb the angle variations when the light module 5 is adjusted horizontally or vertically.
    It will be noted that the spring 15 is found sandwiched between the support 3 and the base 50 (via the nut 31 B, 31 C) of the light module 5.
    At the same time, the threaded rod 17A of the pivot link 7A is inserted into the hole 11A in the base 50 provided for this purpose.
    In a third step, the nut 19B, 19C is screwed onto the threaded rod 17B, 17C. This nut 19B, 19C presses on the support 3. It will be noted that the support 3 is blocked between the spring 15 and the nut 19B, 19C.
    In a fourth step, the nut 19A is screwed onto the rod 17A of the pivot link 7A.
    In a fifth step, in order to adjust the light module 5 respectively horizontally, vertically, the nut 19B, 19C is turned, which brings the light module 5 closer to the support 3 and thus makes it possible to adjust it. The light module 5 pivots relative to the support 3 around the axis 8 seen above. This approximation (which corresponds to pivoting) compresses the spring 15 associated with each threaded rod 17B, 17C. The elastically deformable element 18 is also put into compression due to the pivoting of the light module 5.
    The clearance 01 allows the angle variations to be absorbed when the light module 5 pivots. When the threaded rod 17B, 17C is no longer in motion (ie it is no longer actuated), the spring 15 which is in compression presses on the support 3 and on the base 50 (via the nut 31 B, 31 C) of the light module 5 so that it keeps said light module 5 in position relative to the support 3.
    Of course, in another nonlimiting embodiment, the mounting can start with the insertion of the threaded rod 17B, 17C into the orifice 24B, 24C of the support 3 light module 5.
    Of course, the description of the invention is not limited to the embodiments described above.
    Thus, in another nonlimiting embodiment, the number of light modules 5 in the light device 10 is equal to two or more than 3. Thus, in the case of the second alternative embodiment of the second embodiment of the means of adjustment 7B, 7C (FIG. 8), in a nonlimiting embodiment, the adjustment means 7B, 7C may also comprise a seal placed between the nut 19B, 19C and the support 3.
    Thus, in the case of the first alternative embodiment of the second embodiment of the adjustment means 7B, 7C (FIG. 7), in a nonlimiting embodiment, the adjustment means 7B, 7C may also include a gasket seal arranged between the locking nut 29B, 29C and the base 50.
    Thus, the invention described has in particular the following advantages:
    - the position of the light modules in the light device can be adjusted easily:
    - it makes it possible to propose an adjustment solution which adapts to small light modules;
    - it absorbs vibrations that could occur when the motor vehicle is moving;
    - it allows independent adjustment of different light modules of the light device.
