- the separate threads have specific threads in that they are all oriented in the same direction and in that the threads of a first thread are spaced from a pitch different from that with which are spaced the threads of the second thread.
- the rotation of the screw then generates, for a turn of the screw, a relative displacement of the module with respect to the structural element which is equal to the difference of the pitch of the threads of the two threads.
- the difference between the pitch of the threads of the two threads is less than 0.4 mm per revolution.

- the invention also relates to a motor vehicle comprising a lighting and / or signaling assembly in which the structural element is adapted to carry several modules.
- This assembly is particularly adapted to the implementation on the vehicle of an adaptive beam lighting and control means of the plurality of light sources associated with the lighting modules, since the invention allows a very precise positioning of the modules by relative to the structural element and therefore modules between them, which is a mandatory requirement of a light beam material.

- a device according to the invention makes it possible to fix a lighting module 2 on a structural element 4.
- the fixing device mainly comprises a set of screws consisting of a screw 6 and two nuts 8 and 10, one of which is connected to the lighting module and the other is connected to the structural element.
- the two nuts are stacked axially, that is to say they are arranged along the axis of the screw.
- the screw rod 12 has along its axis two distinct parts of different diameters.
- a proximal portion of the rod 14, disposed in the continuity of the screw head 16, has a larger diameter than a distal portion of the rod 18 at the free end thereof.
- the proximal portion of the rod has on its outer surface a first external thread whose threads, oriented in a certain direction, have a determined pitch.
- the distal portion of the rod has on its outer surface a second external thread, the threads have a different pitch from that of the first thread, being oriented in the same direction as the threads of the first thread.
- a first nut 8 is disposed around the proximal portion of the larger diameter shaft and a second nut 10 is disposed around the distal portion of smaller diameter of the shaft.
- the first nut has on the inner face of a central bore 20 a thread whose direction and the pitch of the threads are adapted to cooperate with the first thread of the screw.
- the second nut has on the inner face of a central bore 22 a thread whose direction and the pitch of the threads are adapted to cooperate with the second thread of the screw.
- each nut 8 has axial stop means and rotational locking means, so as to fix the position of the nuts with respect to the structural element and the module respectively when the screw rotates. , so that a displacement in translation of the screw relative to the nuts is generated, this relative displacement being transmitted to the structural element and to the module due to the axial stopping means.
- the operating principle of such a fixing device is as follows.
- the position of the structural element is adjusted relative to the module, by screwing the clamping screw inside the two nuts respectively integral in displacement of the module and the structural element.
- the screw because it presents according to the invention two threads of slightly different pitch and the same direction, allows to obtain a relative displacement of the structural element relative to that of the module which is smaller, for a turn of the screw, that the value of the pitch of one or the other of the threads.
- the screw When tightening the screw, it advances relative to the first nut disposed around the proximal portion of the rod and made fixed relative to the structural member by the rotational locking means and axial stops.
- the screw is advancing therefore with respect to the structural element and thus tends to approach the module, by screwing into the second nut disposed around the distal portion of the rod. This results in the displacement of the second nut and the integral module to the first nut and the structural member.
- the screw 6 moves relative to the structural element 4 over a distance equal to the value of the pitch P1 of the external thread of the proximal portion of the rod.
- the second nut 10 is screwed into the second nut 10 over a distance equal to the value of the pitch P2 of the external thread of the distal portion of the stem, so that the second nut and the associated module move closer together. to the structural element.
- the displacement of the module relative to the structural element is equal to the value of the pitch of the thread of the proximal portion minus the value of the pitch of the thread of the distal portion (P1-P2).
- this type of attachment is particularly useful in the case where one must place several modules on the same structural element.
- this type of signaling and / or lighting assembly comprising several modules next to each other, which is particularly applied in motor vehicles
- the position of each of the modules should be very precise with respect to the structural element, so that the position of the modules relative to each other corresponds to the specifications and that we can for example proceed to lighting adaptive beam.
- the principle of this type of illumination consists in producing a light beam from a plurality of independent sources, of the light-emitting diode type. Depending on the driving conditions and the identified need to illuminate this or that part of the road, in this or that way, each of the light sources is controlled can be off or on, and in varying degrees of intensity.
- each of the sources In order to obtain a homogeneous beam and which responds efficiently to the lighting control, each of the sources must illuminate very precisely the area assigned to it, and it is therefore necessary for the initial position of the diodes to be as fair as possible. and that it remains reliable over time.
- the mounting tolerances are thus extremely low and the use of fasteners according to the invention for assembling the modules makes it possible to ensure very small mounting gaps.
- Each module is attached to the structural element by means of three fastening means, two of which are adjustable fastening devices according to the invention.
- a first non-adjustable fastening means 24 provides a fixed point which serves from a landmark to adjusting the distance between the module and the structural element.
- the two adjustable fixing devices 26 and 28 are arranged in line with the fixed point, a first 26 being aligned vertically with respect to this fixed point to adjust the vertical position of the assembly while the other 28 is aligned horizontally with respect to this fixed point to adjust the horizontal position of the set.
- the two adjustable fastening devices differ for this purpose in that the locking means in rotation of the second nut allow vertical or horizontal sliding.
- the fixing device mainly comprises a screw 6 and two nuts 8 and 10, of which one is connected to the lighting module 2 and the other is connected to the element 4.
- the fixing device in which in particular the locking means in rotation of the second nut are adapted to cooperate with elements carried by the lighting module, we can refer to FIGS. 6 and the block diagram of Figure 1.
- the screw comprises a hexagonal head 16, to facilitate its gripping by the automated clamping means on the assembly line, and a rod 12 which extends axially with two different diameters.
- the proximal portion of the rod 14 close to the screw head has a larger diameter than the distal portion 18.
- the proximal portion has on its outer surface an external thread, the threads are oriented in a certain sense by presenting a step P1.
- the distal portion also has on its external surface an external thread, whose threads are oriented in the same direction as those of the threading of the proximal portion, but having a pitch P2 different pitch P1.
- the first nut and the second nut are respectively mounted around the thread of the proximal portion and around the thread of the distal portion.
- the first nut 8 has a cylindrical shape with an axis parallel to the axis of the rod. This first nut is pierced with a central through bore 20, of diameter slightly greater than the diameter of the proximal portion of the rod to be threaded around this rod.
- the inner face of the bore has a tapped thread whose orientation and the pitch of the threads make it adapted to cooperate with the external thread disposed on the outer surface of the proximal portion of the rod.
- the first nut further comprises, on its outer surface, means adapted to cooperate with the structural element.
- a collar 36 extends projecting from the outer surface and two diametrically opposed lugs 38 are disposed on the outer surface at an axial distance from the collar substantially equal to the thickness of the structural element.

- the second nut has a cylindrical shape with an axis parallel to the axis of the rod. Again, the second nut is pierced with a central bore 22 slightly larger than the diameter of the distal portion of the rod, to be threaded around the rod.
- the inner face of the bore has a tapped thread whose orientation and the pitch of the threads make it adapted to cooperate with the external threading disposed on the outer surface of the distal portion of the rod.

- cooling means 58 are provided, and different stiffening ribs 60 may be provided on this housing.
- the module comprises three fixing plates each corresponding to a fixing area of the module.
- the two fixing plates 62 and 64 associated with the adjustable fastening devices comprise a vertical plate 66 pierced at its center by an opening bore forming a cavity adapted to receive the spherical head of the second nut, and four lugs 68 projecting of the plate. These four legs are grouped in pairs to form two guideways in the axial direction of the second nut.
- the path formed between the lugs ensures guiding of a lug of the second nut axially and vertically by preventing a horizontal displacement perpendicular to the axis of the screw.
- the path formed between the lugs ensures the guiding of a lug of the second nut horizontally, preventing a vertical displacement.
- a quick-fastening washer 70 is pressed against the vertical plate of the fixing plates, opposite the guide tabs to grip, through deformable inner teeth, the finger extending the head of the second nut. When it is mounted in the mounting plate of the module, the finger protrudes beyond the fixing plate and the washer forms stop means in axial position of the second nut.
- the structural element takes the form of a three-dimensional plate 72 having recesses 74 to allow the passage of cooling means modules.
- the plate has a front face 78 facing the lighting modules and / or signaling when the assembly is mounted, and an opposite rear face 80.
- the structural element Around the recesses, the structural element has for each module a fixed stud 81 which extends in axial projection and whose free end carries a spherical head substantially equivalent to the head formed at the end of the second nut of the adjustable fastening device.
- This fixed stud is adapted to be pressed into the mounting plate of the module corresponding to the fixed fixing area.
- the plate forming the structural element further comprises, for each module, circular bores 82 adapted to be traversed by the adjustable fastening devices, and around which means forming a guide and locking ramp 84 are provided for the fastening of the first nut. relative to the structural element in a bayonet-type fastener.
- the diameter of the bores is substantially equal to the external diameters of the nuts, being less than the diameter of the flange extending projecting from the first nut, so as firstly to allow passage to the screw and the second nut, and other part forming a stop at the collar of the first nut to stop axially insertion of the screw.
- the ramp means extend projecting from the front face 78 and have two diametrically opposed ramp paths 86.
- Each ramp path has an inclined plane which follows the periphery of the edge delimiting the bore, and a housing 88 is formed at the end of the ramp path to receive a lug.
- cutouts are made in the wall delimiting the edge of the bore at the entrance of the ramp paths, so as to form clearances 90 for the passage of the lugs of the nuts.
- the bore, the ramp means and the recesses form an assembly adapted to an insertion of the "push-turn" fastening device specific to a bayonet-type fastener.
- the nut can only rotate in one direction, towards the entrance of a ramp path, since the rotation in the opposite direction is blocked by the presence of an end wall 92 of the other ramp path, forming a shoulder following the symmetrical cuts of the wall.
- the fastener is first assembled by mounting the nuts 8 and 10 on the screw 6, matching the right nut to the corresponding part of the rod.
- the nuts are threaded through the distal portion 18, starting with the first nut 8.
- Its inner diameter substantially equal to the diameter of the proximal portion 14 allows its displacement along the distal portion of smaller diameter without damaging the threads.
- the first nut is then screwed onto the external thread of the proximal portion.
- mount the second nut 10 by screwing it on the external thread of the distal portion, and it is ensured that the lugs 38 and 50 of the two nuts are aligned axially.
- the fixing device is assembled with the structural element 4 by means of the first nut.
- the fastener is passed through the bore 82 of the structural member from the rear of the structural member, first passing the second nut.
- the lugs of the second nut 50 pass through the structural element through the lateral clearances 88 formed on the edge delimiting the bore.
- the insertion of the fixing device is continued until it is in abutment by contact of the collar 36 and the seal 40 against the rear face 80 of the structural element.
- the lugs of the first nut 38 are then passed to the other side of the structural element, having also passed through the bore through the same lateral recesses, the lugs of the first nut and those of the second nut being aligned.
- the first nut is then rotated, so that the lugs of the first nut 38 mount on the ramps 86.
- the rotation of the first nut substantially a quarter turn, is stopped when the lugs take place in the housing 90 arranged in the ramp path.
- the lug is no longer pressed against the front face 76 of the structural element which generates the approximation of the collar of the rear face and the compression of the seal between the structural element and the collar.
- the collar and the lugs of the first nut form axial stop means by axially trapping the structural element, while the housings arranged on the ramp path and the lugs of the first nut form locking means in rotation.
- locking means make it possible to transform the rotational movement of the screw into a translation movement of the first nut and the axial stop means make it possible to make the first nut and the structural element integral in axial displacement when the first nut moves in translation under the effect of the rotation of the screw.
- the module and the structural element are connected by force by making the spherical head of the fixed stud 81 cooperate with the corresponding fixing plate.
- the adjustable fasteners and the module are then connected.
- the spherical head 48 of the second nut is clipped into the platen of corresponding attachment 62, 64 of the module, by guiding axially this head by the cooperation of the lugs of the second nut with the two facing rails formed between the tabs 68 of the mounting plate of the module.
- the assembly is secured by means of a quick coupling means 70, of the deformable washer type, attached to the face of the mounting plate of the module from which the finger extends axially extending the spherical head of the second nut.
- the assembly is then fixed on the body of the vehicle by screwing at the mounting bushings 94 carried by the structural element.
- the invention achieves the goals it has set for itself, and in particular to propose fastening means for easy mounting of the lighting assembly and / or signaling, and with increased accuracy by adjusting the relative displacement of the module and the structural element, this relative displacement can easily be less than 0.4 mm per turn of the screw.
- the fixing device according to the invention allows a high precision while favoring the use of an adjustment screw with standard diameters, which makes it possible to ensure stability of the adjustment over time, the screw not being chosen too small and therefore too fragile.
- the fixing device 101 is generally similar to the device 1 except that the means for locking in rotation of the second nut are carried by the first nut 108, and not by the lighting and / or signaling module 102. This results in a different shape of the first nut and the mounting plate carried by the module.
- the first nut is extended axially so as to cover the second nut, and it has an internal groove adapted to accommodate the integral lug of the second nut.
- the mounting of the nuts on the screw is in an extreme position of assembly of the nuts between them.
- Either the nuts are spaced as far as possible to be threaded together on the screw by the distal portion, and the first nut is first screwed onto the external thread of the proximal portion, or the nuts are grouped together to the maximum; that is to say that the second nut is retracted to the maximum in the first nut, to be threaded together on the screw by the distal portion and first screws the second nut on the distal portion.
- the mounting plate does not have projecting lugs adapted to axially guide the lugs of the second nut.
- the assembly of the fixing device is substantially the same, as is the mounting thereof with the module 102 and the structural element 104, and the operation for the fine adjustment of the position of the module relative to the structure element is the same as before.
