Description

Title of the invention: Light module connecting two bumper skin panels of an automobile

[0001] The invention relates to the field of motor vehicles and more particularly to the front end of motor vehicles. The invention deals with the integration of a lighting module into a bumper skin. The invention also relates to a motor vehicle.

[0002] In some countries, regulations require motor vehicles to be equipped with front-mounted lighting modules that automatically illuminate when the vehicle is in operation. These devices are commonly referred to by the English acronym DRL (Daytime Running Lights). These devices increase the vehicle's visibility during the day, when visibility is low. They are most often integrated into the bumpers, attached to the bumper reinforcement. A more flexible bumper cover is then placed over this reinforcement, and this bumper cover has an opening into which the lighting module is positioned.

[0003] Furthermore, the assemblies of the front end of a motor vehicle contribute significantly to its perceived quality. The connection between the bumper skin, including the panels that compose it on the one hand, and elements such as headlights and light modules on the other hand, must be flush in order to optimize aesthetics and perceived quality, without neglecting the aerodynamics of the vehicle.

[0004] Size constraints apply to the light module, which must be integrated into the bumper. Therefore, given the maximum light intensity of the device in order to avoid dazzling oncoming vehicles and pedestrians, the brightness produced by the device is limited. In certain situations, such as fog or snow, the safety of the vehicle as well as that of oncoming vehicles and pedestrians may be reduced.

[0005] Document FR3121885A1 describes a bumper for a land vehicle. This bumper includes a wall with an opening housing a light assembly. The bumper wall and the light assembly have coupling elements that cooperate to fix the light assembly to the bumper wall. The bumper surrounds the light assembly.

[0006] Document CN204172831U presents a fog light and bumper mounting structure. The structure comprises a bumper skin and a pair of fog light mounting brackets. The bumper skin has an opening, surrounded by mounting brackets and bosses allowing to attach fog lights or daytime running lights. Here again, the bumper cover surrounds the light or light.

[0007] Document EP4289667A1 describes a daytime running light assembly for a motor vehicle. This assembly comprises a light module housed in a casing enclosed by a lens and at least a portion of a bumper having a reinforcement surmounted by a skin, this reinforcement being provided with at least one mounting stud cooperating with a mounting tab of the casing, and said skin having an opening into which the light module is inserted. The light module is fixed to the bumper skin, which surrounds the module in such a way that the lens of said module rests on at least one side against the bumper skin.

[0008] This solution optimizes the connection between the daytime running light and the bumper skin by improving the gaps and flushness. However, there is a need to increase the brightness of the daytime running light in a bumper skin of a given height.

[0009] Furthermore, an impact resulting in damage to the bumper or its casing necessitates the removal of the entire bumper or its casing, even if the damage is limited to a portion of the bumper. There is a need to improve the repairability of the corresponding assembly.

[0044] In the following description, the term "include" is synonymous with "include" and is not limiting in that it permits the presence of other elements in the motor vehicle to which it relates. It is understood that the term "include" includes the terms "consist of". The terms "external" and "internal" shall respectively designate what is oriented towards the outside of the vehicle and towards the inside of the vehicle.

[0045] In this description, the terms "longitudinal," "longitudinally," "transverse," and "transversely" are used with respect to the vehicle's frame of reference in the mounting configuration. The term "longitudinal" refers to the principal direction of travel of the vehicle. The term "transverse" refers to a direction perpendicular to the principal direction of travel of the vehicle.

Indeed, they allow an inclination of at most 25°, preferably at most 10°, more preferably at most 5°, even more preferably at most 2°; in relation to the strict meaning of these terms.

[0048] In this description, the technical characteristics are defined in the assembly mounting configuration, unless otherwise explicitly stated.

[0049] Throughout the description, the different figures use the same reference signs to designate identical or similar entities.

[0050] Figure 1 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.

[0051] The motor vehicle 10 comprises a structure 12. The structure 12 forms an outer body, or the main frame of the motor vehicle. The structure 12 delineates various compartments of the motor vehicle 10, including the passenger compartment, the cargo area, and the engine compartment (not shown). The structure 12 connects various parts of the motor vehicle 10, including the openings. The structure 12 forms a mounting support for the powertrain, steering, suspension, and braking systems (not shown), which are associated with the chassis components 14.

[0052] The structure 12 carries optical units 16 on its front face, providing, for example, the functions of high beams, low beams, and / or turn signals. They provide regulatory lighting. The optical units 16 are lighting units that improve the driver's perception of the environment.

[0053] The structure 12 has a front bumper, referred to as the front bumper 18, on its front face. This front face is also called the front end. The front bumper 18 includes at least one bumper skin reinforcement (not shown). The bumper skin reinforcement is an internal element hidden from view by the end user of the vehicle. This element reinforces the bumper skin 20, which is visible from the outside. The bumper skin 20 is designed to come into contact with the bumper skin reinforcement on its inner face and conforms to it by complementary shape. The bumper skin 20 is attached to the outer face of the bumper skin reinforcement. The bumper skin 20 is generally located below the headlight assemblies 16.

[0054] The bumper skin 20 can be divided into several pieces, forming as many panels. The bumper 18 comprises a transverse panel 22 and a side panel 24, preferably on each side. These panels form a front panel and a longitudinal panel, respectively. The transverse panel 22 is inclined relative to the side panel 24.

[0055] The transverse panel 22 extends transversely across the front face of the structure 12. It extends transversely towards the center of the bumper skin 20. In a known manner, when the vehicle is assembled, the bumper skin 20 may reveal, for example on its transverse panel 22, one or more openings intended for the passage of air for the cooling of an engine and closed by at least one air intake grille 21. These air intake grilles 21 are generally attached to the bumper skin 20 and are fixed there by screws or by means of fixing tabs.

[0056] The transverse panel 22 comprises an external surface, oriented towards the front of the vehicle 10, and an internal surface oriented towards the rear of the vehicle 10. Said internal surface comprises parts enabling its attachment to the bumper reinforcement and to other entities.

[0057] The side panel 24 extends laterally to the wheel arch 26 of the vehicle 10. Said side panel 24 includes a concave edge partially delimiting the wheel arch 26. It is also referred to as a bumper bracket. The side panel 24 comprises an outer surface, oriented towards the outside of the vehicle 10, and an inner surface oriented towards the inside of the vehicle 10. Said inner surface includes the elements enabling its attachment to the bumper reinforcement and to other parts.

[0058] The transverse panel 22 extends transversely with respect to the side panel 24. The transverse panel 22 is arranged transversely towards the inside of the side panel 24. The transverse panel 22 and the side panel 24 are separated by a transverse partition 28. This partition forms a break between the bumper skin panels. Said transverse partition 28 extends vertically over a first height to separate the transverse piece 23 from the side piece 25. These pieces generally form a first piece and a second piece. The transverse partition 28 extends vertically over the entire height of the transverse panel 22. Preferably, the first height is measured transversely along the transverse partition 28.

[0059] The front face of the structure 12 also includes at least one light module 30. This light module 30 includes a light source. Said light source is contained within a vertical housing (not shown). The light module 30 includes an outer lens 34, which covers and seals the vertical housing. The outer lens 34 is flush with the transverse panel 22 and the side panel 24.

[0060] The light module 30 is commonly referred to by the acronym DRL, which stands for "Daytime Running Lights." The light module 30 increases the vehicle's visibility by automatically switching on as soon as the vehicle is in operation; that is, even during the day. According to an option of The invention states that the light module 30 can include the functions of a turn signal and / or fog light, or other lights. The light module 30 can be an auxiliary lighting device. It is located below the optical units 16.

[0061] The light module 30 extends vertically within the transverse partition 28 along its entire first height to close off said transverse partition 28. The light module 30 is positioned between the transverse panel 22 and the side panel 24. Preferably, the outer pane of glass 34 covers the transverse partition 28 along its entire first height. It contributes to the airtight seal. The outer pane of glass 34 is flush with the transverse panel 22 and the side panel 24. The first height encompasses the air inlet grille 21.

[0062] The light module 30 comprises a second height equal to or greater than the first height. Preferably, the transverse panel 22 comprises a third height equal to or less than the second height. Thus, the light module 30 is the most vertically elongated entity at the transverse separation 28. It forms a connecting pillar linking the adjacent panels.

[0063] According to a preferred option of the invention, a lower deflector 36 is fixed under the transverse piece 23 comprising the transverse panel 22 and under the lateral piece 25 comprising the lateral panel 24. This lower deflector 36 is intended to contribute to the aerodynamics of the vehicle 10, while providing protection against projections and elements that may strike the lower body of the moving vehicle 10, to the components located under the structure 12. The vertical housing extends vertically to said lower deflector 36.

[0064] The vertical housing comprises a front face carrying the light source, for example a printed circuit board to which at least one light-emitting diode is connected. The outer glass 34 covers and protects the light source and the front face of the vertical housing. The vertical housing also comprises a rear face, which includes the electrical connections of the light source as well as the elements for attaching the light module 30.

[0065] Figure 2 shows a view of the rear face of the vertical housing 32, attached to the part Side panel 25 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to [Fig. 1]. The front panel is not shown for clarity.

[0066] The vertical housing 32 closes the transverse separation 28. It is fixed to the transverse panel and the side panel 24 to position them relative to each other. The vertical housing 32 conceals the transverse separation 28. It forms a plate closing the transverse separation 28; optionally in combination with the outer pane of glass 34.

[0067] The vertical housing 32 comprises at least one lateral positioning stud 38, preferably several lateral positioning studs 38. The lateral positioning studs 38 define a vertical row. Each lateral positioning stud 38 extends longitudinally. It is generally perpendicular to the vertical housing 32. Each lateral positioning stud 38 is mounted transversely in the transverse partition 28. For example, the at least one lateral positioning stud 38 comprises between two and ten lateral positioning studs. In the present embodiment, three lateral positioning studs 38 are provided, which allows for the definition of a positioning plane. This contributes to the isostatic stability of the assembly.

[0068] The side panel 24 cooperates with the vertical housing 32 at a vertical edge 40 of the side panel 24. The vertical edge 40 extends vertically along the entire height of the side panel 24. The vertical edge 40 is longitudinally opposite the concave edge 41 of the side panel 24. The concave edge 41 defines an arc. It is curved on its rear face. At least one lateral positioning stud 38 extends longitudinally at the vertical edge 40.

[0069] The side piece 25 includes a first reinforcement 58 fixed to the inside of the side panel 24. The first reinforcement 58 conforms to the side panel 24 and extends substantially over its entire length to stiffen it. It forms a lining. It can be welded or bonded to the side panel 24. The side piece includes a first height 78. The first height 78 is measured vertically. It is a maximum height. The first reinforcement 58 is made of material.

[0070] The first reinforcement 58 comprises at least one mounting arm 60 fixed to the vertical housing 32. The mounting arm 60 extends transversely from the inner surface of the side panel 24. It projects inwards. The mounting arm 60 extends transversely at the transverse separation 28, and thus from the vertical housing 32 of the light module 30. Each mounting arm 60 is associated with one of the lateral positioning studs 38, in order to ensure positioning and fixing. This positioning is longitudinal.

[0071] At least one vertical rib 62 extends vertically and connects two successive fixing arms 60. Each vertical rib 62 stiffens the side piece 25 via the first reinforcement 58, and reinforces the support provided via the fixing arms 60.

[0072] Figure 3 shows an enlargement of a lateral positioning stud 38, carried by a vertical housing 32 of a lighting module of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 2. The lateral part, and in particular its mounting arm, is not shown for the sake of clarity.

[0073] The vertical housing 32 includes at least one lateral positioning stud 38. This at least one lateral positioning stud 38 is fixed to the side piece. The lateral positioning stud 38 includes a first longitudinal positioning surface 42. This first longitudinal positioning surface 42 extends transversely and vertically. It joins the side piece at the vertical edge of the side panel. The longitudinal positioning surface 42 is perpendicular to the longitudinal direction.

[0074] This first longitudinal positioning surface 42 has a central hole 44, which is coaxial with a corresponding hole formed on the side panel, in particular on the corresponding mounting bracket. A longitudinal axis passes through these two holes 44. A fastening means, preferably reversible (not shown), for example a screw, is inserted into the hole 44 and the corresponding hole, and allows the side panel and the vertical housing 32 to be joined.

[0075] The lateral positioning stud 38 includes a retention slot 50. The lateral positioning stud 38 is essentially hollow. The retention slot 50 forms a passage, or more generally a retention relief, within it. The retention slot 50 is arranged on a longitudinal face 52 of the stud. The longitudinal face 52 extends longitudinally.

[0076] Figure 4 shows the attachment between a retaining hook 48 and a lateral positioning stud 38 of a motor vehicle assembly. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 3.

[0077] The side piece 25 includes at least one retention hook 48 cooperating with the vertical housing 32. Said retention hook 48 extends longitudinally from the vertical edge of the side panel 24. The retention hook 48 cooperates with the lateral positioning stud 38, for example with the retention slot 50 located on the longitudinal face 52 of the lateral positioning stud 38. Preferably, the side piece 25 includes several retention hooks 48, for example two retention hooks 48 aligned vertically. The retention hooks 48 are made of material.

[0078] The side piece 25 includes at least one transverse positioning orifice 54, the vertical housing 32 including at least one transverse positioning finger 56 engaged in at least one transverse positioning orifice 54. Preferably, the vertical housing 32 includes several transverse positioning fingers 56. Each transverse positioning finger 56 is configured to ensure transverse positioning. In the present embodiment, two positioning fingers are provided, which contributes to the isostaticity of the assembly.

[0079] During assembly, the side panel 24 is positioned longitudinally against the vertical housing 32 by inserting the transverse positioning finger(s) 56 into the corresponding transverse positioning orifice(s) 54. Prefixation is achieved when the retention hook(s) 48 are engaged in the corresponding retention slot(s) 50, after having slid against the longitudinal face 52.

[0080] The final fixing is ensured by introducing an axial fixing means into the orifice of the lateral positioning stud 38 and into the corresponding orifice 46, thus connecting the vertical edge 40 to the lateral positioning stud 38 via the positioning surface carried by the latter.

[0081] Stiffening ribs 64 extend perpendicularly to the fixing arm 60, between said arm 60 and the vertical rib 62. They reinforce the fixing.

[0082] Figure 5 shows a rear view of a vertical housing 32 of a light module 30, assembled with a transverse panel 22 of a bumper skin 20 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 4.

[0083] The vertical housing 32 comprises at least one internal stud 66 fixed to the transverse piece 23, the at least one internal stud 66 being transversely outside the transverse partition 28. Each internal stud 66 extends longitudinally outwards from the motor vehicle; in this case, forwards. Preferably, the at least one internal stud 66 comprises a row of internal studs 66. For example, the vertical housing 32 comprises between two and ten internal studs 66.

[0084] Preferably, the at least one internal stud 66 comprises a second longitudinal positioning surface 68. The second longitudinal positioning surface 68 is perpendicular to the longitudinal direction. It faces the transverse part 23.

[0085] The transverse panel 22 includes at least one support block 70 extending longitudinally. Each support block 70 cooperates with an associated internal block 66. They are in longitudinal contact to ensure longitudinal positioning. For example, each support block 70 extends rearward from the inner face of the transverse panel 22. The at least one support block 70 includes a bearing surface perpendicular to the longitudinal direction. The bearing surface cooperates with the second longitudinal positioning surface 68 to position the transverse panel 22 and the vertical housing 32.

[0086] The at least one support block 70 comprises a row of support blocks. Preferably, the at least one support block 70 comprises between two and ten support blocks. The number of support blocks 70 is equal to the number of internal blocks 66. The support blocks 70 and the internal blocks 66 are positioned opposite each other in the assembly.

[0087] According to one embodiment of the invention, the transverse piece 23 comprises a second reinforcement 84 fixed to the inside of the transverse panel 22, the second reinforcement 84 comprising at least one support pad fixed to the housing. The second reinforcement 84 is fixed to the transverse panel 22. It conforms to its internal surface.

[0088] The light module 30 includes a second height 80. The second height 80 is measured vertically. The second height 80 can be the height of the vertical housing 32. It is greater than or equal to the first height. The transverse panel 22 includes a third height 82 that is less than or equal to the second height 80. Thus, the light module 30 forms a main pillar of the assembly. It supports and stiffens it.

[0089] Figure 6 shows a close-up view of a vertical positioning tab 74 cooperating with the vertical housing 32 of the motor vehicle according to the invention. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 5.

[0090] The transverse panel 22 includes at least one support block 70 extending longitudinally rearward from the inner face of the transverse panel 22. The inner block 66 is essentially hollow. The at least one support block 70 includes a stop surface that cooperates with the second longitudinal positioning surface 68 of the inner block 66 to fix the transverse panel 22 and the vertical housing 32. The stop surface extends vertically and transversely. It is covered by the inner block 66.

[0091] The second longitudinal positioning surface 68 has a hole 72 in its center, coaxial with a corresponding hole located on the (non-visible) abutment surface of the support block 70. A longitudinal axis passes through these two holes. This longitudinal axis is a geometric axis. A fastening means, preferably reversible (not shown), for example a screw, is inserted into the holes and secures the transverse panel 22 and the vertical housing 32.

[0092] The transverse part 23 includes at least one vertical positioning tab 74 cooperating with the vertical housing 32 in order to vertically position said vertical housing 32 relative to the transverse part 23.

[0093] The vertical housing 32, preferably the internal stud 66, includes a retention slot 76. The retention slot 76 runs longitudinally through the internal stud 66. The vertical positioning tab 74 cooperates with the internal stud(s) 66. It is engaged in the retention slot 76. The retention slot 76 is formed in the second longitudinal positioning surface 68.

[0094] The embodiment with a retention slot 76 receiving a vertical positioning tab 74 contributes to isostaticity. It eliminates one degree of freedom. However, other numbers of slots and tabs can be chosen.

[0095] During assembly, the transverse panel 22 is positioned longitudinally against the vertical housing 32 by inserting the vertical positioning tab 74 into the corresponding retention slot 76. Final fastening is achieved by inserting an axial fastening means into the hole 72 and the corresponding hole located on the abutment surface of the support block 70, thus connecting the support block 70 to the internal block 66 via the second longitudinal positioning surface 68 carried by the latter.

[0096] The support block 70, the vertical positioning tab 74 and the reinforcement are made of material.

[0097] The reinforcements and the vertical housing are made of a plastic or composite 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, vinyl ester, 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.

[0098] The vertical housing, the lateral positioning stud(s), and the internal stud(s) are integrally made of a material, for example, plastic. The plastic material used for the vertical housing is different from that of the bumper skin panels; it is more rigid.

[0099] The assembly shown in Figures 1 to 5 is preferably an assembly applied to the front of a motor vehicle, and therefore to the front bumper of said vehicle. According to another embodiment of the invention, this assembly is applied to the rear of a motor vehicle. The lighting module used then comprises at least a rear light, and / or a reversing light, and / or a turn signal.
