Description

Title of the invention: System for adjusting the orientation of a light device for a motor vehicle.

[0001] The invention relates to a system for adjusting the orientation of a light device for a motor vehicle. The invention further relates to a motor vehicle equipped with such an adjustment system.

[0002] Generally, motor vehicles are equipped with lighting devices which are configured to provide a lighting function. In particular, motor vehicles are equipped with headlights at the front of the vehicle, these headlights provide a high beam function and / or a low beam function: they are configured to project a light beam in order to create at least one lighting zone in front of a motor vehicle for visibility functions.

[0003] In order to ensure the safety of drivers of motor vehicles, it is important for them to be able to adjust the direction in which the light beam from these lighting devices is projected. More particularly, it is important for a driver to be able to adjust the inclination of said light beam. Indeed, the inclination of the light beam from these lighting devices has an impact on the range of said beam, that is to say on the extent of the illuminated area at the front of the vehicle. Control systems for adjusting the angle of inclination of a light beam from a lighting device arranged at the front of a motor vehicle are generally available to drivers of said motor vehicle.

[0004] An example of such a system for adjusting the orientation of a lighting device generally comprises an interface such as a manual control connected to a cable which, when the manual control is actuated by a user, induces a movement of said cable, which modifies the height of a lighting module (also called a "light projector") of the lighting device and thus modifies the angle of inclination of the light beam coming from said lighting device.

[0005] In this type of system for adjusting the orientation of a lighting device, the precision of the adjustment is affected by the length of the cable(s) which connect the interface (i.e. the manual control) to the lighting module. However, this interface is generally located inside the passenger compartment, close to the driver's position, for example next to the steering wheel, while the lighting module is included in a lighting device generally located on a front face of the motor vehicle. The cable(s) which connect these two elements are therefore quite long, which can be a source of inaccuracy in adjusting the height of the lighting module.

[0006] Thus, such a system for adjusting the orientation of a light device does not allow not to guarantee reliable repeatability of the positions of the lighting module or light projector over time, which means that the angle of inclination of the light beam from the lighting device may be subject to variations, which is not optimal for the safety of road users.

[0007] The aim of the invention is to remedy the drawbacks described above.

[0008] To this end, the invention relates to a system for adjusting the orientation of a light device for a motor vehicle, the adjustment system comprising: - a case; - an interface intended to be operated by a user; - a control device movable between several positions and configured to interact with a lighting module so as to modify its orientation; - an elastic return element such as a helical coil spring arranged inside the housing, between the control device and an inner wall of the housing; the adjustment system being characterized in that it further comprises a selector arranged between the interface and the control device, the selector being mounted to move relative to said control device, so that manipulation of the interface by a user causes the selector to move, the selector comprising several bearing surfaces against which the control device is intended to come into abutment, the control device occupying a separate position for each bearing surface of the selector in abutment against the control device.

[0009] Furthermore, such a mechanical adjustment system for adjusting the orientation of a lighting device generally proves to be more economical than an electronic adjustment system.

[0010] According to one embodiment, the selector comprises between two and ten distinct bearing surfaces against which the control device is intended to come into abutment.

[0011] According to one embodiment, the bearing surfaces are flat or concave.

[0012] According to one embodiment, the selector is a part that is mobile and rotates relative to to the control device.

[0013] According to one embodiment, the axis of rotation around which the selector pivots relative to the control device is eccentric relative to the center of said selector.

[0014] According to one embodiment, the selector has a prism shape with polygonal bases.

[0015] According to one embodiment, a pivot angle of the selector is between 60° and 360°, it is more particularly equal to 180°.

[0016] According to one embodiment, the selector is a part that moves in rectilinear translation.

[0017] According to one embodiment, the selector has a rack shape and the support surfaces of the selector are formed by notches of the rack, said notches having different heights from each other.

[0018] The invention also relates to an arrangement comprising an adjustment system as described above, the arrangement also comprising a lighting device comprising a base and a lighting module, the lighting module being mounted to be movable in rotation relative to said base, the position of the lighting module relative to the base being dependent on the position of the control device in abutment against one of the support surfaces of the selector of the adjustment system.

[0019] The invention also relates to a vehicle equipped with such a system for adjusting the orientation of a lighting device or equipped with an arrangement as described above.

[0020] These objects, characteristics and advantages of the present invention will be explained in detail in the following description of a particular embodiment made without limitation in relation to the attached figures among which:

[0028] [Fig.3B] schematically illustrates the adjustment system of [Fig.3A] in a second position.

[0029] [Fig.3C] schematically illustrates the adjustment system of Figures 3A and 3B in a third position.

[0030] [Fig.3D] schematically illustrates the adjustment system of Figures 3A, 3B and 3C in a fourth position.

[0031] [Fig.3E] schematically illustrates the adjustment system of Figures 3A to 3D in a fifth position.

[0032] In [Fig.l] is illustrated a system 1 for adjusting the orientation of a luminous device 2 of a motor vehicle known from the state of the art. For reasons of clarity and visibility, the different components of the adjustment system 1 illustrated in [Fig.l] are not shown on the same scale.

[0033] The adjustment system 1 of a lighting device 2 known from the state of the art comprises an interface 3, in particular a manual control, such as a lever or a wheel arranged within easy reach of the driver's position of the motor vehicle, for example at the steering wheel. This interface 3 is then intended to be manipulated by a user of the motor vehicle, in particular a driver.

[0034] In this same [Fig.l], the lighting device 2 comprises a base 5 configured to serve as a base for a lighting module 7 of the lighting device 2. The lighting module 7 is configured to emit a light beam F, in particular in an area located at the front of the motor vehicle equipped with such a lighting device 2 and such an adjustment system 1 for said lighting device 2. The lighting module 7 thus provides a light projector function. The lighting module 7 is mounted to be able to rotate relative to said base 5. More particularly, the lighting module 7 can pivot or tilt relative to the base 5, which makes it possible to modify the direction in which the light beam F from the lighting device 2 is emitted.

[0035] The adjustment system 1 known from the state of the art illustrated in [Fig.l] also comprises a connecting means 9 which connects the interface 3 to a control device 10. As illustrated in this [Fig.l], the connecting means 9 is in the form of a cable attached on the one hand to the interface 3 and on the other hand to the control device 10 of the lighting module 7. Thus, manipulation of the interface 3 by a user causes a translational movement of the cable, which causes a movement of the control device 10, which induces a pivoting of the lighting module 7 relative to the base 5 of the lighting device 2 so as to modify the direction in which the light beam F from the lighting module 7 is emitted.

[0036] The control device 10 is for example movable in translation inside a housing 12 of the adjustment system 1. Thus, when a user actuates the interface 3 so as to move the cable of the connecting means 9 relative to the housing 12, this causes a rectilinear translational movement of the control device 10 relative to this housing 12. The travel of the control device 10 is of the order of a few millimeters, it is for example less than or equal to 10 mm.

[0037] An elastic return element 13 such as a helical coil spring is arranged inside the housing 12 of the adjustment system 1, between the control device 10 and an inner wall of the housing 12. The elastic return element 13 is configured to oppose the displacement induced by the cable of the connecting means 9, this makes it possible to guarantee the stability of the position of the control device 10. In this way, a direct impact between the control device 10 and the inner walls of the housing 12 can be avoided.

[0038] With this adjustment system 1 known from the state of the art, the slightest change in position of the manual control which forms the interface 3 has a direct impact on the position of the control device 10 and therefore on the position of the lighting module 7. It is therefore difficult to obtain a precise and repeatable position over time of the lighting module 7 with such an adjustment system 1 known from the state of the art.

[0039] Figures 2A to 2E illustrate a lighting device 2 and a system 1 for adjusting the orientation of said lighting device 2 of a motor vehicle according to a first embodiment of the invention. For reasons of clarity and visibility, the various components of the adjustment system 1 illustrated in Figures 2A to 2E are not shown to the same scale. The adjustment system 1 illustrated in Figures 2A to 2E also comprises an interface 3, in particular a manual control, such as a lever or a wheel arranged within easy reach of the motor vehicle driver's position, for example at the steering wheel.

[0040] As shown in Figures 2A to 2E, the lighting device 2 also comprises a base 5 configured to serve as a base for a lighting module 7 which is mounted to be able to rotate relative to said base 5. This lighting module 7 is configured to emit a light beam F, in particular in an area located at the front of the motor vehicle equipped with such a lighting device 2 and such a system 1 for adjusting the orientation of said lighting device 2.

[0041] Furthermore, the adjustment system 1 may comprise a housing 12 inside which is housed a part of a control device 10, so that a free end of said control device 10 protrudes from the housing 12 to interact with the base 5 and / or with the lighting module 7 of the lighting device 2. Here again, the control device 10 is movable in translation inside the housing 12 of the adjustment system 1, as in the case of the adjustment system 1 known from the state of the art illustrated in [Fig.l].

[0042] An elastic return element 13 such as a helical coil spring is arranged inside the housing 12 of the adjustment system 1, between the control device 10 and an inner wall of the housing 12. The elastic return element 13 is configured to oppose the movement induced by the cable of the connecting means 9, this makes it possible to guarantee the stability of the position of the control device 10. In this way, a direct impact between the control device 10 and the inner walls of the housing 12 can be avoided.

[0043] The adjustment system 1 illustrated in FIGS. 2A to 2E also comprises a means connecting means 9 which connects the interface 3 to a control device 10 of the lighting module 7. Again, the connecting means 9 may comprise one or more cables. A portion of the connecting means 9 is attached to the interface 3.

[0044] The adjustment system 1 further comprises a selector 14 arranged between the interface 3 and the control device 10 of the lighting module 7. The selector 14 is for example a part made of ABS (Acrylonitrile butadiene styrene) plastic, but other types of plastics can be envisaged. Metallic materials can also be envisaged for manufacturing the selector 14. As illustrated in FIGS. 2A to 2E, the selector 14 is arranged inside the housing 12 of the adjustment system 1.

[0045] The selector 14 is mounted to be movable relative to the control device 10 of the adjustment system 1. More particularly, the connecting means 9 is connected to the selector 14 so that manipulation of the interface 3 by a user causes the selector 14 to move. According to a particular embodiment, the selector 14 may be secured to another part 15, such as a disc or a flywheel for example, and in this case the connecting means 9 may be attached to said disc or flywheel, as in the embodiment illustrated in FIGS. 2A to 2E. Alternatively, the connecting means 9 may be connected to an edge of the selector 14 or a peripheral surface of the selector 14.

[0046] Thus, when a user manipulates the interface 3 of the adjustment system 1, the selector 14 is moved and the control device 10 also, which induces a pivoting of the lighting module 7 so as to modify the direction in which the light beam F coming from the lighting module 7 is emitted. The travel of the control device 10 is for example of the order of a few millimeters. In a preferred embodiment, the travel of the control device 10 is less than or equal to 10 mm. The travel of the control device 10 is more particularly between 3 mm and 10 mm.

[0047] In a manner common to all embodiments, the selector 14 comprises several bearing surfaces 16 against which the control device 10 is intended to come into abutment. The position of the control device 10 is distinct for each bearing surface 16 of the selector 14 against which it comes into abutment. Furthermore, the position of the lighting module 7 relative to the base 5 of the lighting device 2 depends on the position of the control device 10 in abutment against one of the bearing surfaces 16 of the selector 14. More particularly, it is the inclination of the lighting module 7 relative to the base 5 which depends on the position of the control device 10 against one of the bearing surfaces 16 of the selector 14. Thus a discrete number of distinct positions is conferred on the lighting module 7 relative to the base 5 depending on the bearing surface 16 of the selector 14 against which the control device 10 is in abutment.

[0048] The selector 14 comprises, for example, between two and ten separate bearing surfaces 16 against which the control device 10 is intended to come into abutment. The number of bearing surfaces 16 determines the number of positions that the lighting module 7 can adopt relative to the base 5 within the lighting device 2. In other words, the number of bearing surfaces 16 determines the number of different positions for the inclination of the light beam F coming from the lighting device 2 and therefore the different ranges of the light beam F on the illuminated zone at the front of the vehicle by said lighting device 2.

[0049] According to a first embodiment, the selector 14 comprises five distinct bearing surfaces 16 and is therefore configured to adopt five distinct positions. In this embodiment, the control device 10 and the lighting module 7 can therefore adopt five positions different from each other, which means that the driver can therefore choose from five different angles of inclination to direct the light beam F coming from the lighting module 7. As illustrated in FIGS. 2A to 2E, the five different bearing surfaces 16 are numbered “0”, “1”, “2”, “3” and “4”. The extreme bearing surfaces 16 then correspond to the bearing surfaces 16 which bear the numbers “0” and “4”.

[0050] A first position of the control device 10 correlated to a first position of the lighting module 7 is illustrated in [Fig. 2A]. When the control device 10 is in this first position, it abuts against the bearing surface 16 which bears the number “4”. A second position of the control device 10 correlated to a second position of the lighting module 7 is illustrated in [Fig. 2B]. When the control device 10 is in this second position, it abuts against the bearing surface 16 which bears the number “3”. Similarly, a third position, a fourth position and a fifth position of the control device 10 correlated respectively to a third position, a fourth position and a fifth position of the lighting module 7 are illustrated respectively in FIGS. 2C, 2D and 2E.

[0051] Preferably but optionally, the bearing surfaces 16 of the selector 14 may be at least partially covered with a protective coating configured to protect said bearing surfaces 16 against abrasion and / or against repeated impacts of the control device 10 against said bearing surfaces 16.

[0052] Additionally or alternatively, the bearing surfaces 16 may be flat or each have a curved surface so as to be slightly concave. The curved bearing surfaces 16 may make it possible to guide the control device 10 towards the center of a bearing surface 16 in question and thus ensure the accuracy of the position of the control device 10 against the bearing surface 16 in question. Alternatively, the flat bearing surfaces 16 are generally easier, more eco- economical and less time-consuming to manufacture.

[0053] According to another embodiment not illustrated, the bearing surfaces 16 of the selector 14 may comprise a groove configured to guide the control device 10 intended to come into abutment against the different bearing surfaces 16 of the selector 14 during the movement of the selector 14. In other words, in this embodiment, the groove(s) present on the different bearing surfaces 16 of the selector 14 make it possible to guide the control device 10 from a starting bearing surface 16 to an arrival bearing surface 16 during the movement of the selector 14 induced by the manipulation of the interface 3 by a user.

[0054] According to the embodiment illustrated in FIGS. 2A to 2E, the selector 14 is a part that can move in rotation relative to the control device 10. In other words, the selector 14 is configured to pivot around an axis of rotation X when a user actuates the interface 3 of the adjustment system 1.

[0055] In this embodiment, the control device 10 intended to come to bear against the different bearing surfaces 16 of the selector 14 is moved in translation when the selector 14 pivots about its axis of rotation X. More particularly, one end of the control device 10 in contact with the selector 14 slides from the starting bearing surface 16 against which it was bearing and over the other bearing surface(s) 16 which are presented facing the control device 10 during the pivoting of the selector 14 about its axis of rotation X until the control device 10 is again bearing against an arrival bearing surface 16 chosen by the user to adjust the position of the lighting module 7 relative to the base 5 of the lighting device 2 in order to reach the desired angle of inclination for the light beam F coming from the lighting device 2.

[0056] A pivot angle of the selector 14 may be between 60° and 360°. The pivot angle corresponds to the maximum rotation angle provided for the movement of the selector 14 around its axis of rotation X. The pivot angle of the selector 14 may more particularly be equal to 180°.

[0057] An intermediate pivot angle of the selector 14 between two consecutive positions of the lighting module 7 depends on the one hand on the total pivot angle of the selector 14 and on the other hand on the number of bearing surfaces 16 of this same selector 14. The intermediate pivot angle of the selector 14 between two consecutive positions of the lighting module 7 is in particular equal to the pivot angle of the selector 14 divided by the number of bearing surfaces 16 of this same selector 14. For example, a selector 14 may have a pivot angle of 180° and five distinct bearing surfaces 16 distributed all around the periphery of the selector 14. In this particular case, the pivot angle of the selector 14 for two consecutive positions of the lighting module 7 is 36°.

[0058] In the embodiment illustrated in Figures 2A to 2E, the axis of rotation X around which the selector 14 is movable is eccentric relative to the center of said selector 14. An axis of rotation X eccentric of the selector 14 makes it possible to accentuate the difference in position of the control device 10 from one bearing surface 16 to another while allowing a compact design for the selector 14. Such an axis of rotation X eccentric relative to the center of the selector 14 can make it possible to limit the pivot angle of the selector 14 while allowing a clear distinction between the different bearing surfaces 16 of this selector 14, the bearing surfaces 16 of this selector 14 can then be distributed over a smaller portion of the periphery of the selector 14.

[0059] In the embodiment illustrated in Figures 2A to 2E, the selector 14 has a prism shape with polygonal bases. The shape of the polygonal bases depends on the number of bearing surfaces 16 that one wishes to have for the selector 14 and the number of bearing surfaces 16 of the selector 14 depends on the number of distinct positions that one wishes to have for the lighting module 7. The bearing surfaces 16 may have different sizes. Thus, the polygonal-shaped bases are not necessarily regular polygons.

[0060] According to a non-illustrated embodiment, the selector 14 can be configured to have a pivot angle of 360° and this selector 14 can then have a prism shape with pentagonal bases. In this particular example, the selector 14 therefore has five distinct bearing surfaces 16 which are distributed over the entire periphery of the selector 14 and the control device 10 can therefore adopt five different positions depending on the bearing surface 16 against which it is in abutment for a given position of the selector 14. Consequently, the lighting module 7 of the lighting device 2 can adopt five distinct angles of inclination relative to the base 5 of the lighting device 2 and the light beam F can be inclined in five different ways.

[0061] In the embodiment illustrated in Figures 2A to 2E, the selector 14 also has five distinct bearing surfaces 16, but which are distributed over a portion of the periphery of the selector 14. Furthermore, another type of surface is present between two neighboring bearing surfaces 16: this is a transition surface configured to facilitate the repositioning of the control device 10 when the selector 14 pivots to switch from one bearing surface 16 to a neighboring bearing surface 16. In other words, the transition surfaces 17 present between two neighboring bearing surfaces 16 form ramps on which the control device 10 moves to move from one bearing surface 16 to another, for example by sliding on these transition surfaces 17.

[0062] As illustrated in Figures 2A to 2E, the selector 14 may include at least one wall 18 or a rampart configured to prevent the control device 10 from sliding of the selector 14 when the control device 10 is in abutment against one of the end bearing surfaces 16 of the selector 14.

[0063] In this same embodiment, an elastic return element such as a torsion spring may be arranged between the selector 14 and the housing 12 of the adjustment system 1. This elastic return element is configured to exert a force on the selector 14 to return it to a rest position. The elastic return element is not visible in FIGS. 2A to 2E. The rest position of the selector 14 corresponds in particular to the position adopted by the selector 14 when the control device 10 is in abutment against the bearing surface 16 which bears the number “4”, as illustrated in [Fig. 2A]. More generally, the rest position of the selector 14 corresponds to one of the extreme positions of the selector 14 and therefore to an extreme position of the control device 10, but it is possible to have a rest position of the selector 14 which is correlated to an intermediate position of the control device 10.

[0064] According to a second embodiment illustrated in Figures 3A to 3E, the selector 14 is a part that can move in rectilinear translation. For reasons of clarity and visibility, the various components of the adjustment system 1 illustrated in Figures 3A to 3E are not shown on the same scale. As illustrated in Figures 3A to 3E, the selector 14 is arranged inside a housing 12 in which the control device 10 is also arranged. A sliding connection then allows the selector 14 to be moved in rectilinear translation relative to the housing 12 when a user interacts with the interface 3 of the adjustment system 1. As illustrated in Figures 3A to 3E, the direction of movement of the selector 14 is perpendicular to the direction of movement of the control device 10.In Figures 3A to 3E, the directions of movement for the selector 14 on the one hand and for the control device 10 on the other hand are represented by arrows.

[0065] In this same second embodiment, the selector 14 has, for example, a rack shape. The bearing surfaces 16 of the selector 14 are then formed by notches of the rack. More particularly, the notches have different heights from each other and thus form the distinct bearing surfaces 16 of the selector 14. As illustrated in FIGS. 3A to 3E, the shape of the rack of the selector 14 recalls the shape of a staircase; the steps of said staircase then form the bearing surfaces 16 of the selector 14 against which the control device 10 is intended to come into abutment.

[0066] In the embodiment illustrated in Figures 3A to 3E, the selector 14 comprises five distinct bearing surfaces 16, this selector 14 is therefore configured to adopt five distinct positions which are all illustrated in these Figures 3A to 3E. In this embodiment, the control device 10 and the lighting module 7 can therefore adopt five different positions from each other, which means that the driver can therefore choose from five different inclination angles to direct the light beam F coming from the light device 2. As illustrated in Figures 3A to 3E, the five different bearing surfaces 16 are numbered “0”, “1”, “2”, “3” and “4”. The extreme bearing surfaces 16 then correspond to the bearing surfaces 16 which bear the numbers “0” and “4”.

[0067] A first position of the control device 10 correlated to a first position of the lighting module 7 is illustrated in [Fig. 3A]. When the control device 10 is in this first position, it abuts against the bearing surface which bears the number “4”. A second position of the control device 10 correlated to a second position of the lighting module 7 is illustrated in [Fig. 3B]. When the control device 10 is in this second position, it abuts against the bearing surface which bears the number “3”. Similarly, a third position, a fourth position and a fifth position of the control device 10 correlated respectively to a third position, a fourth position and a fifth position of the lighting module 7 are illustrated respectively in FIGS. 3C, 3D and 3E.

[0068] In this same second embodiment of the selector 14, another type of surface may be present between two neighboring support surfaces 16: this is a transition surface 17 configured to facilitate the repositioning of the control device 10 when the selector 14 is moved to switch from one support surface 16 to a neighboring support surface 16. In other words, the transition surfaces 17 present between two neighboring support surfaces 16 form ramps on which the control device 10 moves to move from one support surface 16 to another, for example by sliding on these transition surfaces 17.

[0069] As illustrated in Figures 3A to 3E, the selector 14 may comprise at least one wall 18 or a rampart configured to prevent the control device 10 from sliding off the selector 14 when the control device 10 is in abutment against one of the end bearing surfaces 16 of the selector 14.

[0070] In the embodiment illustrated in Figures 3A to 3E, an elastic return element 19 such as a tension-compression spring, in particular a helical spring, may be arranged between the selector 14 and the housing 12 of the adjustment system 1. This elastic return element 19 is configured to exert a force on the selector 14 to return it to a rest position. As illustrated in [Fig.3A], the rest position of the selector 14 corresponds in particular to the position that it adopts when the control device 10 is in its first position, that is to say when it is in abutment against the bearing surface 16 which bears the number “4”. More generally, the rest position of the selector 14 corresponds to one of extreme positions of the selector 14 and therefore to an extreme position of the control device 10, but it is possible to have a rest position of the selector 14 which is correlated to an intermediate position of the control device 10.

[0071] It is thus possible to design different embodiments of a selector 14 for a system 1 for adjusting the orientation of a lighting device 2 for a motor vehicle in which the selector 14 makes it possible to confer a discrete number of distinct positions to a lighting module 7 relative to a base 5 of the lighting device 2 as a function of the bearing surface 16 of the selector 14 against which the control device 10 of the adjustment system 1 is supported, so as to orient the light beam F coming from the lighting device 2 in a precise and repeatable manner.
