Description

Title of the invention: Motor vehicle lighting assembly

[0001] The invention relates to pedestrian impact against a motor vehicle lighting assembly. The invention relates more specifically to a front lighting assembly with a double lighting device for a motor vehicle. The invention also relates to a motor vehicle.

[0002] In a motor vehicle, it is necessary to provide in the design an architecture that allows pedestrians to be protected in the event of an impact. In particular, it is imperative to reduce possible injuries inflicted on a leg, at the femur. To do this, it is necessary to guarantee a certain amount of sinking of the vehicle in order to absorb sufficient energy when the leg enters. It is also necessary to guarantee a relatively rectilinear sunken shape so as not to break the leg before the pedestrian then impacts the hood.

[0003] Document CN104203647B discloses a motor vehicle comprising a headlight and a device for mounting the headlight on structural elements of the vehicle. The headlight comprises a housing body, the housing houses at least one light source and is adapted to be installed at least partially along an edge of a vehicle wing. The mounting device comprises a connecting piece of the rod type which pivots about a fixed axis of rotation relative to a structural element of the vehicle constituted by the technical front face of the vehicle supporting the powertrain of the vehicle.A cooling assembly whose axis of rotation is contained within a longitudinal plane of the vehicle and is positioned such that a collision along a stress line on one side of the axis of rotation causes one edge of the headlamp to rise above the adjacent edge of the fender on the other side of the axis of rotation, and the shape of the headlamp is defined by the axes of rotation are determined and oriented so that the headlamp pivots about the axes of rotation.

[0004] It is also common to have front lights on the front bumper of the vehicle, located below the headlight, generally these front lights are relatively off-center transversely towards the outside of the vehicle so as not to be in the central area affected by the leg impact; also called pedestrian impact window.

[0005] However, with the style developments and the desire to have three luminous claws in the front lights, the latter are therefore much wider. They extend into the pedestrian impact window. Such front lights form rectangular or parallelogram blocks. In the event of an impact, their depression and tilting is constrained by the headlight and the adjoining transverse beams placed behind the bumper skin.

[0006] Therefore, these front lights risk absorbing little kinetic energy. In addition In the event of an impact against a pedestrian's leg, when a light remains blocked forward, an angle may form between a front light and the headlight arranged above. Such an angle causes a tilt of the leg which could fracture the femur.

[0007] The invention aims to address at least one of the problems or drawbacks encountered in the prior art. In particular, the invention aims to improve the safety of a motor vehicle. The invention also aims to optimize the compactness, mass, and control of the kinematics of sinking a light assembly of a motor vehicle.

This bias facilitates the control of the tilting kinematics of the lower light module, and its ability to avoid obstacles in the bumper assembly. These shapes create contact zones between the lower light module and the upper headlight making it possible to orient the axis of rotation during the most favorable impact. This allows compact movement of the front light without interference with the structure of the vehicle during a pedestrian impact.

[0053] In the present description, the pedestrian impact refers to an adult pedestrian of average height; that is to say, approximately 1.75 m tall.

[0054] Throughout the description, the different figures use the same reference signs to designate identical or similar entities.

[0055]

[0056] [Fig.l] represents a motor vehicle 10 according to the invention. The motor vehicle 10 comprises energy storage means and at least one motor (not shown) adapted to drive said motor vehicle 10.

[0057] The motor vehicle 10 comprises a structure 12. The structure 12 forms an outer body, or even a main frame of the motor vehicle. The structure 12 connects different parts of the motor vehicle 10 including the openings. The structure 12 forms a mounting support for the powertrain, the suspension systems, the steering system, the braking systems. The structure 12 partially forms the body 14 of the vehicle at the level of the roof, the front wings, the pillars. The body 14 forms the external envelope of the motor vehicle 10.

[0058] The bodywork 14 comprises in particular a front hood 16. The front hood 16 is an opening providing access to a front compartment. It is movable between a closed position and an open position. In the event of a collision with a pedestrian 30, the front hood 16 accommodates the pedestrian 30, in particular his head.

[0059] The motor vehicle 10 further comprises a front bumper assembly 18, such as a front fascia assembly. The front bumper assembly 18 comprises bumper skin elements, air intake grilles, at least one crossmember 20. The front bumper assembly 18 has an arcuate shape across the width of the motor vehicle, which improves aerodynamics. The crossmember 20 is a transverse and horizontal beam. It contributes to absorbing collision energy against fixed obstacles. The crossmember 20 is connected to the structure 12 using box members 22; for example at the ends of front side members (not shown) of the structure 12. The boxes 22 are energy-absorbing devices, also referred to by the English expression “crashbox”. They are configured to deform for collisions against fixed obstacles for speeds greater than or equal to 50 km / h.

[0060] The front bumper assembly 18, in particular each of its elements, is adapted to withstand impacts at speeds up to 10 km / h, preferably up to 15 km / s, without there being any need to replace specific parts of the vehicle, and in particular all or part of the bumper skin. The front bumper assembly 18 is also adapted to limit the extent of injuries in the event of a pedestrian impact.

[0061] The motor vehicle 10 further comprises at least one front light assembly 24, preferably a front light assembly 24 on each side of the motor vehicle 10. Each front light assembly 24 comprises an upper headlight 26 and a lower light module 28. The upper headlight 26 is a regulatory headlight, capable of illuminating in front of the motor vehicle 10. It comprises daytime running lights and headlights. It may comprise at least one lens and at least one curved internal reflective surface, defining a focal length with one of the light sources (not shown). The upper headlight 26 is generally a first light device, and / or a rear light device. It is under the front hood 16. The lower light module 28 is generally a second light device, and / or a front light device.

[0062] The lower light module 28 is configured to emit a lower light intensity than that of the upper projector 26. In particular, it provides comfort lighting, especially when stationary. The lower light module 28 extends in front of the upper projector 26. It is placed underneath. Their housings overlap vertically. The lower light module 28 comprises at least one vertical light strip 78, preferably at least two vertical light strips 78 which are offset transversely. The crosspiece 20 is under the lower light module 28, preferably vertically distant from the lower light module 28. The at least two vertical light strips 78 are parallel.

[0063] In the description, the characteristics described in relation to a lower light module 28 apply to each lower light module 28; and those described in relation to one of the upper projectors 26 apply to each upper projector 26.

[0064] A pedestrian 30 is shown in front of the motor vehicle 10. In particular, one of his legs 32 is in front of one of the front light assemblies 24. This leg 32 is exposed to the lower light module 28 in the event of a collision.

[0065] The motor vehicle may, for example, be a private motor vehicle or a utility motor vehicle.

[0066] [Fig.2] shows an upper projector 26 of a front light assembly motor vehicle. The motor vehicle corresponds to that shown in relation to [Fig.l].

[0067] The upper projector 26 comprises an upper housing 34, and having at least one front surface 36; such as a front interface zone. The upper projector 26 is a main projector. The upper housing 34 is closed by a transparent front glass 38. The upper housing 34 houses at least one light source such as one or more light-emitting diodes. These light sources are associated with at least one lens, and / or an internal reflective surface making it possible to orient the light rays forward. The upper housing 34 includes an optical axis (not shown). The optical axis corresponds to the main or average direction of light ray emission.

[0068] The front light assembly has a longitudinal direction 40. The longitudinal direction 40 is horizontal. It is parallel to the X axis. The longitudinal direction is along the optical axis. Those skilled in the art understand that the longitudinal direction 40 corresponds to the main emission direction of the upper projector 26.

[0069] The front surface 36 comprises two front facets 37 offset transversely and longitudinally. They contribute to defining the tilting axis 42 in the event of contact with the rear surface of the lower light module. The front facets 37 define the tilting axis 42. It passes through the front facets 37. The front surface 36, and in particular its two front facets 37, are formed by the upper housing 34. During pedestrian impact, and therefore during tilting of the lower light module, the tilting axis 42 slides vertically along the front facets 37; and more generally along the front surface 36.

[0070] The upper projector 26 comprises a lower housing 44 delimited by the front surface 36, and each of its portions. The lower housing 44 extends transversely. The lower housing 44 is open towards the front and towards the bottom.

[0071] The upper projector 26 comprises several fixing lugs 46 extending from the upper housing 34. The fixing lugs 46 comprise frangible zones in order to break in the event of a collision with a pedestrian. The fixing lugs 46 are vertically spaced from the front surface 36, so as not to disturb the kinematics of the lower light module in the event of a pedestrian impact.

[0072] [Fig. 3] shows a lower light module of a front light assembly for a motor vehicle. The motor vehicle corresponds to that shown in relation to one of Figures 1 to 2.

[0073] The lower light module 28 comprises a lower housing 48. The lower light module 28 is hollow. It contains electrical connections. It comprises light sources, such as light-emitting diodes. The light sources may be arranged in matrices. It may comprise light guides.

[0074] The lower light module 28 comprises a rear surface 50 intended to be opposite the front surface of the upper projector (not shown) so as to form a tilting interface with a tilting axis 42 relative to the upper projector. The tilting axis 42 is inclined relative to the longitudinal direction 40 by a first angle 52 of between 30° and 60°.

[0075] The lower housing 48 comprises at least two studs 54 offset along the longitudinal direction 40. The studs 54 comprise ends 56 forming the rear surface 50. The ends 56 are rear ends. Thus, the rear surface 50 forms two abutment surfaces 76 offset transversely and longitudinally. The ends 56 form the abutment surfaces 76. The abutment surfaces 76 are longitudinal stops. The studs 54 form reinforcements making it possible to materialize the abutment surfaces 76.

[0076] The tilting axis 42 is horizontal; inclined by at most 10°, preferably at most 5° relative to the horizontal. The tilting axis 42 passes through the ends 56 and the stop surfaces 76. More precisely, the tilting axis 42 is formed by the lower points of the stop surfaces 76 since they form points physically coming into contact with the front surface in the event of a pedestrian impact.

[0077] The lower housing 48 comprises a width greater than or equal to 10 cm; preferably greater than or equal to 20 cm. The lower housing 48 comprises a rear box 58 which forms the rear surface 50 and which is intended to be housed in the lower housing of the upper projector. The studs 54 are on the rear face of the rear box. The rear box 58 forms an upper block extending longitudinally towards the rear.

[0078] [Fig. 4] shows a front light assembly 24 of a motor vehicle, before and after a pedestrian impact. The motor vehicle corresponds to that shown in relation to one of Figures 1 to 3. The cross member 20 is arranged underneath. The lower light module 28 is shown in solid lines in the folded position following a pedestrian impact, and in positions in the mounting configuration.

[0079] The lower light module 28 comprises a rear surface facing the front surface 36 of the upper projector 26. These surfaces are configured so as to form a tilting interface 60 with a tilting axis 42 relative to the upper projector 26. The tilting axis 42 is inclined relative to the longitudinal direction (not shown) and the transverse direction 62, that is to say relative to the X axis and the Y axis.

[0080] The tilting axis 42 is inclined relative to the longitudinal direction by a first angle (not shown) of between 30° and 60°, in order to fold the lower light module 28 transversely inward and downward in the event of a pedestrian impact. As shown in the present illustration, in the retracted configuration, the lower light module 28 converges toward the center of the bumper assembly and downward when pushed rearward. Thus, it has an elongated stroke, which facilitates absorption of the energy of the pedestrian impact.

[0081] The lower light module 28 extends transversely over at least half of the upper projector 26. The upper projector 26 comprises a lower housing 44 forming the front surface 36. The lower housing 48 comprises a rear box 58 which forms the rear surface and which is housed in the lower housing 44. The rear box 58 and the lower housing 44 have functional clearances in order to allow a de- relative placement.

[0082] The length 64 of the lower light module 28 under the rear surface is less than the distance 66 between the rear surface and the cross member 20. This difference in measurements allows the lower light module 28 to tilt around the cross member 20. The length 64 and said distance 66 can be measured from the lower ends of the rear surface, and / or measured perpendicular to the tilting axis 42. The length 64 is a maximum length. The distance 66 is a minimum distance.

[0083] [Fig. 5] shows a front light assembly 24 of a motor vehicle, in the mounting configuration and seen from below. The motor vehicle corresponds to that shown in relation to one of Figures 1 to 4.

[0084] In this mounting configuration, the tilting interface 60 is open. Along the tilting interface 60, the lower light module 28 remains at a distance from the upper projector 26. It respects a first clearance 68. The first clearance 68 is measured in the longitudinal direction 40. The first clearance 68 between the rear surface 50 and the front surface 36. The first clearance 68 is a minimum clearance, measured longitudinally between the lower light module 28 and the upper projector 26.

[0085] The tilting interface 60 comprises a second clearance 70 which is greater than the first clearance 68. The second clearance 70 is a transversely internal clearance and the first clearance 68 is a transversely external clearance. This difference in clearances allows tilting around the vertical axis in the event of a pedestrian impact. By offsetting them transversely, this allows the tilting direction to be oriented inwards. The second clearance 70 and the first clearance 68 are formed between the pads 54 and the front facets 37 of the front surface 36

[0086] The lower housing 48 is adjacent to the upper housing 34. The lower housing 48 of the lower light module 28 comprises a main elongation axis 72 inclined relative to the longitudinal direction 40 by a second angle 74 of between 30° and 60°. This arrangement makes it possible to match the surface of the bumper assembly, and therefore to comply with aerodynamic constraints.

[0087] [Fig. 6] shows a front light assembly 24 of a motor vehicle, in a first intermediate configuration of deformation during a pedestrian impact against the lower light module 28. The motor vehicle corresponds to that presented in relation to one of figures 1 to 5.

[0088] Due to the impact, the lower light module 28 moves back relative to the upper projector 26. The tilting interface 60 becomes narrower. The first gap 68 closes until, on the outside, the stud 54 reaches the associated facet 37. The second gap 70 decreases.

[0089] [Fig.7] shows a front light assembly 24 of a motor vehicle, in a second intermediate configuration of deformation during a pedestrian impact against the lower light module 28. The latter is still closer to the upper headlight 26. The motor vehicle corresponds to that presented in relation to one of figures 1 to 6.

[0090] The first set 68 remains closed, while the second set 70 closes in turn. The two studs 54 come into abutment with the facets 37. The front surface 36 meets the rear surface; materializing the tilting axis 42 of the tilting interface 60 which has become even more refined.

[0091] The main elongation axis 72 of the lower housing 48 of the lower light module 28 is parallel to the tilting axis 42. The tilting axis 42 is inclined by 30° and 60°, preferably between 40° and 50°, relative to the transverse direction 62. This inclination subsequently allows tilting transversely inwards.

[0092] [Fig.8] shows a front light assembly 24 of a motor vehicle, in a deformation configuration at the end of a pedestrian impact, the lower light module 28 which folds under the upper headlight 26 and transversely towards the inside. The motor vehicle corresponds to that presented in relation to one of figures 1 to 7.

[0093] The tilting axis 42 is inclined relative to the longitudinal direction 40 by a first angle 52 of between 30° and 60°, preferably between 35° and 55°, more preferably between 40° and 50°. These angles promote a compact configuration at the end of the impact.

[0094] Thanks to the contact between the studs 54 and the facets 37, or more generally between the rear surface 50 and the front surface 36, the lower light module 28 pivots at the level of the tilting interface 60. The lower light module 28 rotates on itself, and disappears under the upper projector 26. Its vertical light strips 78 are oriented downwards. Thus, it adopts a less protruding position. It facilitates the entry of the leg into the front light assembly 24; and limits the risks of injury to a femur.

[0095] According to a preferred embodiment, the lower housing and the upper housing are made of a plastic or composite material. The plastic material may comprise a thermoplastic material or a thermosetting material. According to a preferred embodiment, the plastic material is selected from the group comprising polypropylene, polyamide, polyphthalamide, polyetheretherketone, polyphenylene sulfide, polyamide-imide, polyetherimide, polyarylamide, polyepoxide, unsaturated polyester, vinylester or polyester-vinylester resins. For example, the composite material comprises a matrix of a plastic material as described above with a reinforcement. For example, the reinforcement comprises glass or carbon fibers. These materials provide mechanical resistance allowing the tilting movement of the lower light module 28 by coming into contact, then by bearing against the upper projector 26 in the event of pedestrian impact.

[0096] The invention provides a three-stage deformation of the front light assembly 24. It first follows a longitudinal translation, then a pivoting along the vertical axis; then a tilting around the tilting axis. This kinematics increases the travel path and therefore the potential for energy absorption by the motor vehicle. In addition, this succession of rotations avoids the cross member as much as possible. Therefore, the movement of the front light assembly 24 is not hindered, and allows the leg to be kept straight; hence a safety gain.

[0097] The invention comprises the combination of all the embodiments shown by all the figures.

[0098] Figures 2 to 8 are isometric views. They each respect a specific scale.
