Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a light device for a motor vehicle.

It finds a particular but non-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.

It is also known to use plastic capsules fixed to a light module to adjust the positioning of a light module on the support. Each capsule cooperates with a ball head screw forcefully inserted into said capsule. The light module comprises a fixed point (ball joint connection) and two screws to force 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. However, it is not possible to reduce the size of the capsules too much because they risk breaking when the screws are inserted into them.

In this context, the present invention aims to solve the aforementioned drawback.

GENERAL DESCRIPTION OF THE INVENTION

To this end, the invention provides a light device for a motor vehicle, said light device comprising:

- a support ;

- at least one light module;

- at least one connection suitable for mounting the light module on the support, said connection comprising:

- a rod connected to one of the light module and the support;

- a capsule connected to the other of the light module and the support, said capsule comprising:

- At least two separate portions each made of an elastically little deformable or undeformable material; said at least two separate portions being complementary so as to form a cavity when they are assembled to receive part of the rod;

- A constraint means to maintain the separate portions assembled so as to prevent a withdrawal of said part of the rod out of the cavity.

Thus, as will be seen in detail below, the capsule comprises at least two separate portions made of an elastically little deformable or undeformable material. The two separate portions are held in place by a restraint that provides elasticity to the entire capsule. The two separate portions are adapted to take an open position and a closed position. In the open position the two separate portions are distant and it is possible to bring part of the rod at the level of these two separate portions. The restraining means stretches so that the capsule opens to let part of the rod pass. In the closed position, the two separate portions are brought together to form a cavity suitable for receiving and blocking part of the rod. In this closed position, the two separate portions are maintained by the constraint means. This part of the rod is held in the capsule by the pressure of the constraint means on the separate portions. It is thus possible to produce capsules of small sizes which retain good mechanical strength.

In other words, the two portions are made of a rigid material and advantageously the two portions have identical shapes. The constraint means is in particular arranged so as to be elastically more deformable than the material or materials of the two portions.

According to non-limiting embodiments, the light device can also include one or more additional characteristics among the following:

According to a nonlimiting embodiment, the material of the two separate portions of the capsule is a material:

- thermoplastic loaded with glass fibers; or

- in steel.

According to a nonlimiting embodiment, the capsule is secured to the support and the rod is connected to the light module.

According to a nonlimiting embodiment, the capsule is integral with a base 25 of the light module and the rod is connected to the support.

According to a nonlimiting embodiment, the constraint means is a spring.

According to a nonlimiting embodiment, the capsule comprises a groove adapted to receive the constraint means, said groove extending over the periphery of the two separate portions.

According to a nonlimiting embodiment, the two separate portions delimit an evacuation orifice adapted to evacuate the air from the cavity during the reception of the part of the rod.

According to a nonlimiting embodiment, the part of the rod has a shape without sharp edges.

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 8.

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.

The light device 10 comprises

- a support 3;

- at least one light module 5;

- at least one link 7 adapted to mount the light module 5 on the support 3.

In a nonlimiting embodiment, the light device 10 comprises a plurality of light modules 5 adapted to be mounted on a support 3 via links 7.

In the nonlimiting example illustrated in FIG. 1, the light device 10 comprises three light modules 5 adapted to be mounted on a support each by means of three links 7.

FIG. 2 schematically illustrates a light module 5 fixed by three links 7A, 7B, 7C.

Each link 7A, 7B, 7C respectively comprises a rod 9A, 9B, 9C which cooperates with a capsule 11 A, 11 B, 11 C.

In a nonlimiting embodiment, the first link 7A is adapted to form a pivot link (also called a fixed point) between the light module 5 and the support 3. The pivot link allows the light module 5 to rotate in the vertical Y or horizontal Z directions.

The second link 7B is adapted to vertically block the light module 5, that is to say block said light module 5 in a direction

Y, called vertical direction.

The third link 7C is adapted to block the light module 5 horizontally, that is to say block said light module 5 in a direction

Z, called horizontal or lateral direction.

The rod 9A is screwed into the capsule 11A so as to form the first connection 7A. This first rod 9A has a part 90 (described below) taken in the cavity 15 of the capsule 11A. The rod 9A is adapted to be screwed into a threaded hole 18A (described below) of the base 50 of the light module 5 or of the support 3 of the light device 10, so as to cause the adjustment of the light beam 12 produced by the light module 5 when an operator operates said rod 9A

The rod 9B is screwed into the capsule 11B so as to form the second connection 7B.

The rod 9C is screwed into the capsule 11C so as to form the third connection 7C.

The first link 7A, the second link 7B and the third link 7C allow precise adjustment of the position of the light module 5 relative to the support 3. In particular, the second link 7B and the third link 7C allow precise adjustment in vertical and horizontally of the light beam 12 produced by the light module 5.

In a nonlimiting embodiment, the light module 5 can serve as a reference module for positioning other light modules in the light device 10. In this case, it has three connections 7 which are pivot connections and the three connections 7 are at the same level and can be adjustable or not. This reference module is positioned along the axis of the road as a function of the photometric function determined.

Thus, the light beam 12 produced by this light module 5 serves as a reference beam for the adjustment of the other light beams 12 of the other light modules 5. The other light beams 12 can thus be adjusted vertically and horizontally so as to be aligned with the reference beam and so as to create an overall light beam of the light device 10.

Thanks to the links 7, each light module 5 can be adjusted independently of the other light modules 5.

The various elements of the light device 10 are described in detail below.

o Light module

As also illustrated in FIG. 7 and FIG. 8, each light module 5 comprises:

- an optical means 6 mounted in the light module 5;

- A base 50 adapted to allow the fixing of the light module 5 on the support 3;

- a light source 8 comprising light emission means (not shown).

In a nonlimiting embodiment, as illustrated in FIGS. 7 and 8, the base 50 is integral with the optical module 6.

The light source 8 is adapted to emit light rays forming a light beam 12.

When the light device 10 comprises a plurality of light modules 5 as illustrated in FIG. 1, said light modules 5 form a matrix called "matrix beam". The set of light beams 12 of the different light modules 5 then forms a global light beam also called a matrix light beam.

In a nonlimiting example, the overall 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 overall light beam of the light device 10 is adapted to provide a photometric function called "low beam" to achieve, for example, a low beam.

In a nonlimiting embodiment, the optical means 6 is:

- a reflector; and or

- a lens.

It will be noted that the support 3 of the light device 10 comprises an opening 16 through which the light beam 12 passes.

In the nonlimiting example illustrated in FIGS. 7 and 8, the optical means 6 is a reflector secured to the base 50 of the light module 5.

The optical means 6 cooperate with the light source 8 described below to form the light beam 12.

In addition to the light emission means, the light source 8 includes an electrical connection interface (not shown). The electrical connection interface is suitable for power supply and 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 8 and to supply it.

In a nonlimiting embodiment, the light emitting means comprise at least one semiconductor emitting chip.

In a nonlimiting variant, 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").

o Support. disposi t 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.

o Liaison

As illustrated in FIGS. 6 to 8, each of the links 7 of a light module 5 comprises:

- a capsule 11; and

- a rod 9.

The rod 9 and the capsule 11 are described in detail below.

o Capsule

As illustrated in FIG. 3, the capsule 11 comprises:

- at least two separate portions 13A, 13B; and

- a means of restraint 17.

In a nonlimiting embodiment, the capsule 11 comprises a diameter of less than five millimeters.

In a nonlimiting embodiment, the capsule 11 is of cylindrical shape.

The separate portions 13A, 13B are each made of an elastically little deformable or undeformable material.

In nonlimiting embodiments, the material of the two separate portions 13A, 13B of the capsule 11 is a material:

- thermoplastic loaded with glass fibers; or

- in steel.

These embodiments make it possible to obtain a capsule 11 which has good mechanical strength, in particular for capsules of small formats, in contrast to capsules made of non-loaded thermoplastics such as, for example, acetane polyamide resin.

In a nonlimiting variant, the steel material is brass, bronze, etc.

The separate portions 13A, 13B are complementary so as to form a cavity 15 (illustrated in FIGS. 4 to 6) when they are assembled to receive a part 90 (described below) of the rod 9.

In a nonlimiting embodiment, the separate portions 13A, 13B each respectively comprise two upper flats 130A, 130B and lower 130A ’, 130B’. The upper flats 130A, 130B serve as a support surface for the rod 9 when the latter is inserted into the capsule 11.

In a nonlimiting embodiment, the separate portions 13A, 13B each further comprise, respectively, a wall 14A, 14B which are opposite one another when the two separate portions 13A, 13B are assembled. The walls 14A, 14B thus form a space for receiving another part of the rod 9, the intermediate part 91 (described below).

The constraint means 17 is adapted to keep the separate portions 13A, 13B assembled so as to prevent the part of the rod 9 from being withdrawn from the cavity 15. It is further adapted to move apart when the rod 9 is inserted in force in capsule 11.

In a nonlimiting embodiment, the constraint means 17 is metallic.

In a nonlimiting embodiment, the constraint means 17 is a spring. The spring which surrounds the capsule 11 makes it possible to give elasticity to the whole of the capsule 11. The spring 17 is of circular shape when the capsule 11 is of cylindrical shape. It thus forms a ring around the capsule 11.

In a nonlimiting embodiment illustrated in FIG. 3, the capsule 11 further comprises a groove 21 which extends over the periphery of the two separate portions 13A, 13B. This groove 21 is adapted to receive the constraint means 17, in particular said spring. Note that this groove is circular when the spring is circular.

In a nonlimiting embodiment illustrated in FIG. 6, the two separate portions 13A, 13B delimit an exhaust orifice 25 adapted to evacuate the air from the cavity during the reception of the part 90 (described below) of the rod 9. This prevents the air from being compressed at the bottom of the capsule 11, which would prevent good insertion of the end portion 90 of the rod 9 into said cavity 15.

This discharge port 25 comprises a first part of port 25A belonging to the first separate portion 13A and a second part of port 25B belonging to the second separate portion 13B. In addition, the evacuation orifice 25 makes it possible to absorb the manufacturing tolerances of the part 90 (described below) of the rod 9 as well as its deformations.

o .l.JSL ©

As illustrated in FIG. 6, in a nonlimiting embodiment, the rod 9 comprises:

- a flat part 93;

- a threaded part 92;

- an intermediate part 91;

- a part 90 called the end part.

The different parts of the rod 9 are described in detail below.

The flat part 93 allows an operator to press on the rod 9 and then to screw it (with a screwdriver for example).

The threaded part 92 is adapted to be screwed either in the base 50 of the light module 5 (as illustrated in a first mounting method of FIG. 7 described below) or in the support 3 (as it is illustrated in a second mounting mode of Figure 8 described below).

In another nonlimiting embodiment, the rod 9 does not have a threaded part but means for connection to a motor or to the pinions of an adjustment device fixed on the support 3.

The intermediate part 91 is disposed between the threaded part 92 and the end part 90. It has a reduced section relative to the end part 90 and to the threaded part 92. It is sandwiched between the two walls 14A and 14B of the capsule 11 when the latter is in the closed position. In this way, the end part 90 cannot be taken out of the cavity 15.

The end portion 90 is adapted to come to be housed in the cavity 15 formed by the two separate portions 13A, 13B of the capsule 11. The shape of the cavity 15 is complementary to the shape of the end portion 90 to ensure good locking of the end part 90 in the capsule 11. In a nonlimiting embodiment illustrated in FIGS. 6 to 8, the end part 90 comprises a shape without sharp edges. This makes it possible to have a snag-free contact between the end portion 90 and the bottom of the capsule 11. This thus avoids having a stress point in the capsule 11 which would risk weakening said capsule 11 mechanically.

The capsule 11 is adapted to be in a closed position and an open position as described below.

In the open position, the end portion 90 of the rod 9 can enter the capsule 11 or exit from the capsule 11. Thereafter, it is the tension present in the constraint means 17 which makes it possible to return the capsule 11 to its closed position. In the closed position, the end portion 90 remains trapped in the capsule 11.

o Pps it ion of closure. of. the cap on

As illustrated in FIG. 6, the capsule 11 is in a closed position.

In this position:

- the two separate portions 13A, 13B are assembled so as to form a cavity 15 into which the end portion 90 of the rod 9 is inserted. The two separate portions 13A, 13B hold the end portion 90 in the capsule 11. The assembly and the maintenance is made possible by means of constraint 17;

- The first wall 14A of the first portion 13A and the second wall 14B of the second portion 13B are opposite. The first wall 14A and the second wall 14B are in contact with each other outside the passage 27 in order to allow rotation of the rod 9 as well as a clearance for adjusting the light beam 12 of the light module 5. They maintain the intermediate part 91 in the capsule 11. This maintenance is made possible by means of constraint 17;

- The constraint means 17 is housed in the circular groove 21 of the capsule 11. It has a sufficient holding force to allow the two separate portions 13A, 13B to be joined together after the insertion of the end portion 90 of the rod 9 in the cavity 15. The constraining means 17 thus makes it possible to tighten the two separate portions 13A, 13B and to maintain the intermediate part 91 and the end part 90 in the capsule 11;

the evacuation orifice 25 is formed by the two distinct portions 13A, 13B which are assembled, in particular by the first portion of orifice 25A of the first distinct portion 13A and the second portion of orifice 25B of the second portion separate 13B. Thus, it is the bringing together of the first part of orifice 25A with the second part of orifice 25B which makes it possible to form said evacuation orifice 25.

o Capsule opening position

As illustrated in Figure 5, the capsule 11 is in an open position.

In this position:

- The two separate portions 13A, 13B are spaced so as to allow the insertion of the end portion 90 in the capsule 11. The constraint means 17 is then stretched to the maximum to make this spacing possible between the two separate portions 13A , 13B.

- The first wall 14A of the first portion 13A and the second wall 14B of the second portion 13B These walls 14A, 14B define a passage 27 for the insertion of the end portion 90 into the capsule 11.;

- The constraint means 17 is housed in the circular groove 21 of the capsule 11. It has sufficient elasticity to allow spacing between the two separate portions 13A, 13B in order to insert the end portion 90 of the rod 9 into the cavity 15. The constraint means 17 thus has sufficient elasticity to allow the two separate portions 13A, 13B to move away under the action of an external force, such as the action of an operator on the flat part 93. The constraint means 17 makes it possible to hold the two separate portions 13A, 13B together.

The mounting of a light module 5 on the support 3 of the light device 10 through connections 7 is described below according to two non-limiting embodiments.

o First mode of realization

As illustrated in FIG. 7, the light device 10 comprises the light module 5 mounted on the support 3. The optical means 6 of the light module 5 cooperate with the light source 8 to form the light beam 12. This light beam 12 is adapted to pass through the support 3 at the opening 16.

The light module 5 is mounted on the support 3 by means of three connections 7A, 7B, 7C (the last connection not being shown). For the remainder of the description, only the links 7A, 7B are described with reference to FIG. 7. The description which will be described for the links 7A and 7B also applies to the link 7C.

As already specified, each link 7A, 7B respectively comprises a rod 9A, 9B and a capsule 11 A, 11 B.

In this first mounting method, the capsules 11 A, 11B are integral with the support 3 and the rods 9A, 9B are connected to the light module 5.

In a nonlimiting embodiment, one of the separate portions in each capsule 11 A, 11B is secured to the support 3, the other portion being movable relative to this portion secured to the support 3.

In nonlimiting embodiments, this joining is carried out by molding or by gluing.

The integral portion and the movable portion of each capsule 11 A, 11B are held together respectively by a constraint means 17A, 17B.

To mount the light module 5 on the support 3, the optical means 6 are brought into the opening 16 of the support 3 and the base 50 of this light module 5 is placed on the capsules 11 A, 11 B, integral with the support 3, in particular on the upper flats 130A, 130B of the separate portions 13A, 13B.

In this position, the capsules 11 A, 11B are respectively opposite with two threaded holes 18A, 18B belonging to the base 50. The threaded holes 18A, 18B are adapted to receive the threaded parts of the rods 9A, 9B. In order to accommodate the end parts 90 of the rods 9A, 9B in the cavities of the capsules 11 A, 11 B, an operator presses (with a screwdriver for example) on the flat part 93A, 93B of each rod 9A, 9B so that the end portions 90 press on the upper flats 130A, 130B of the separate portions 13A, 13B.

When the operator screws the rods 9A, 9B, the separate portions 13A, 13B move away from one another so that the capsules 11 A, 11B are in the open position. These are in particular the separate movable portions of the capsules 11 A, 11B which move. The constraint means 17A, 17B associated with each capsule 11 A, 11B is stretched. The actuation of the rods 9A, 9B thus allows a separation of the separate portions 13A, 13B because the insertion force of the rods 9A, 9B counterbalances the force of the constraint means 17A, 17B which keeps the two separate portions 13A, 13B assembled.

The displacement of the separate movable portions of the capsules 11 A, 11B makes it possible to create sufficient space between the walls 14A, 14B of each capsule 11 A, 11B to allow each end portion 90 of the rods 9A, 9B to pass. The operator has pressed enough on each rod 9A, 9B. When each end portion 90 is completely pressed into the capsule 11 A, 11 B, namely when it is fully inserted into the corresponding cavity 15, the constraint means 17, here the spring in the nonlimiting example taken, allows to reposition the capsules 11 A, 11B in a closed position, namely to assemble the separate portions 13A, 13B corresponding to each other.

The separate parts 13A, 13B of the capsules 11 A, 11B will then block the end parts 90 of the rods 9A, 9B in the cavities 15 of the capsules 11 A, 11 B.

The light module 5 is thus mounted on the support 3.

o Second mgd_e_ de.réalisation

As illustrated in FIG. 8, the light device 10 comprises the light module 5 mounted on the support 3. The optical means 6 of the light module 5 cooperate with the light source 8 to form the light beam 12. This light beam 12 is adapted to pass through the support 3 at the opening 16.

The light module 5 is mounted on the support 3 by means of three connections 7A, 7B, 7C (the last connection not being shown). For the remainder of the description, only the links 7A, 7B are described with reference to FIG. 7. The description which will be described for the links 7A and 7B also applies to the link 7C.

As already specified, each link 7A, 7B respectively comprises a rod 9A, 9B and a capsule 11 A, 11 B.

In this second mounting method, the capsules 11 A, 11B are integral with the base 50 of the light module 5 and the rods 9A, 9B are connected to the support

3.

In a nonlimiting embodiment, one of the separate portions in each capsule 11 A, 11B is secured to the base 50, the other portion being movable relative to this portion secured to the base 50.

In nonlimiting embodiments, this joining is carried out by molding or by gluing.

The integral portion and the movable portion of each capsule 11 A, 11B are held together respectively by a constraint means 17A, 17B.

To mount the light module 5 on the support 3, the optical means 6 are brought into the opening 16 of the support 3 and the capsules 11 A, 11 B are placed, integral with the base 50, on the support 3, in in particular the lower flats 130A, 130B 'of the separate portions 13A, 13B.

In this position, the capsules 11 A, 11B are respectively opposite one another with two threaded holes 18A, 18B belonging to the support 3. The threaded holes 18A, 18B are adapted to receive the threaded parts of the rods 9A, 9B. In order to accommodate the end parts 90 of the rods 9A, 9B in the cavities of the capsules 11 A, 11 B, an operator presses (with a screwdriver for example) on the flat part 93A, 93B of each rod 9A, 9B so that the end portions 90 press on the lower flats 130A, 130B 'of the separate portions 13A, 13B.

When the operator screws the rods 9A, 9B, the separate portions 13A, 13B move away from one another so that the capsules 11 A, 11B are in the open position. These are in particular the separate movable portions of the capsules 11 A, 11B which move. The constraint means 17A, 17B associated with each capsule 11 A, 11B is stretched.

The actuation of the rods 9A, 9B thus allows a separation of the separate portions 13A, 13B because the insertion force of the rods 9A, 9B counterbalances the force of the constraint means 17A, 17B which keeps the two separate portions 13A, 13B assembled.

The displacement of the separate movable portions of the capsules 11 A, 11B makes it possible to create sufficient space between the walls 14A, 14B of each capsule 11 A, 11B to allow each end portion 90 of the rods 9A, 9B to pass. The operator has pressed enough on each rod 9A, 9B. When each end portion 90 is completely pressed into the capsule 11 A, 11 B, namely when it is fully inserted into the corresponding cavity 15, the constraint means 17, here the spring in the nonlimiting example taken, allows to reposition the capsules 11 A, 11B in a closed position, namely to assemble the separate portions 13A, 13B corresponding to each other.

The separate parts 13A, 13B of the capsules 11 A, 11B will then block the end parts 90 of the rods 9A, 9B in the cavities 15 of the capsules

11 A, 11 B.

The light module 5 is thus mounted on the support 3.

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 another nonlimiting embodiment, the number of separate portions forming the capsule is greater than two.

Thus, in another nonlimiting embodiment, the capsule 11 is of square shape.

Thus, in another nonlimiting embodiment, the capsule 11 does not have an evacuation orifice 25.

Thus, the invention described has the following advantages in particular:
