Description

Title of the invention: Motor vehicle structure with front foot reinforcement piece

[0001] The invention relates to the safety of passengers in a motor vehicle in the event of a frontal collision. More particularly, the invention deals with the reinforcement of the structure in the event of a frontal collision, especially one with minimal overlap. The invention relates to a motor vehicle structure comprising a front support bracket. The invention relates to a motor vehicle.

[0002] Safety standards relating to a front impact that a motor vehicle may undergo require that the forces resulting from this impact be transmitted to the vehicle structure via a rigid connection in order to dissipate the impact forces as much as possible throughout the structure, so as to preserve as much as possible the integrity of the passenger compartment of the motor vehicle and its occupants.

[0003] On each side, three load paths distribute the forces during a frontal collision. One path is formed by the frame rail, which directs the forces primarily towards the underbody of the motor vehicle. A lower path directs the forces via the engine cradle. A third path runs along the vehicle's suspension strut mounts and directs the forces directly towards the front pillar, also known as the front axle of the motor vehicle.

[0004] The front strut must be able to maintain its integrity, as well as that of the assemblies with its surroundings, so as to minimize intrusions into the passenger compartment. However, the different tracks are offset vertically and transversely from one another. This configuration places even greater stress on the front strut.

[0005] The front foot is subjected to greater stress the heavier the vehicle. The type of stress also varies depending on the type of crash test protocol required by safety standards. Consider, for example, a frontal impact against a fixed barrier offset from the vehicle. This offset implies a small overlap, that is, a transverse overlap of no more than 25%.

[0006] The area comprising the connection between the apron and the front support, located at the base of the cowl, constitutes a weak point susceptible to deformation and resulting in the apron protruding into the passenger compartment. Solutions developed to address this problem typically involve reinforcing this connection area between the apron and the front support by increasing the thickness of the components subjected to these forces. However, such an increase in thickness generally translates into an increase in the overall mass of the vehicle, since the parts involved are extensive. In a context where energy efficiency is sought, such an increase in mass is not desirable.

[0007] Document FR2919562B1 describes a motor vehicle comprising a structure with a front pillar. A front crossmember includes a lower bay crossmember connected to an upper bulkhead. A right front pillar includes a right front fender liner and a pillar reinforcement connected to each other and forming a closed profile. A right side support is located approximately halfway up the pillar. The front pillar is equipped with an L-shaped front pillar reinforcement. The reinforcement rests on the dashboard crossmember support, which is itself attached to the front pillar.

[0008] However, it is desirable to improve the system to move towards a solution that is simple in terms of assembly, while limiting the increase in the vehicle's mass as much as possible. It is also desirable to reduce the number of parts.

[0009] The invention aims to address at least one of the problems or drawbacks encountered in the prior art. In particular, the invention aims to increase the safety of passengers in a motor vehicle.

[0050] 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.

[0051] 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 20°, preferably at most 10°, more preferably at most 5°, and even more preferably at most 2°; with respect to the strict meaning of these terms.

[0055] In this description, the technical characteristics are defined in the mounting configuration of the structure, unless otherwise explicitly stated.

[0056] Throughout the description, the different figures use the same reference signs to designate identical or similar entities.

[0057] 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.

[0058] 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 14, the front compartment 16, and the cargo area (not shown). The structure 12 may be formed from an assembly of stamped and welded sheet metal parts.

[0059] The structure 12 connects various parts of the motor vehicle 10, including the openings. The structure 12 forms a mounting support for the powertrain, suspension systems, steering system, and braking systems (not shown).

[0060] The structure 12 includes front side members extending along the front compartment 16. The front side members include upper side members 18, forming a third track, such as an upper track. They can be curved to form horns. The front side members further include cross members below the upper side members and above the engine cradle (not shown).

[0061] The motor vehicle 10 comprises a subframe 20. The subframe 20 comprises side members, including lower side members 22. The lower side members 22 extend along the passenger compartment 14. They extend from the front wheel arches to the rear wheel arches. They form the main side members of the structure 12.

[0062] The structure 12 also has front pillars 24, also called front feet. The front pillars 24 are located in front of the passenger compartment 14. The front pillars 24 are vertically aligned with the front compartment 16. The front pillars 24 are below the windshield 30, which is bordered laterally by the window pillars 26. The window pillars extend vertically from the front pillars 24. The front pillars 24 extend vertically above the lower side members 22. The motor vehicle 10 includes a right front pillar and a left front pillar. The front doors 38 are attached to the front pillars 24 by means of hinges 66.

[0063] The structure 12 also includes a transverse partition 28 forming a vertical wall. The transverse partition 28 is a front apron. The transverse partition 28 It forms a separation between the front compartment 16 and the passenger compartment 14. It is located under the windshield 30. The transverse partition 28 extends vertically. It connects the front pillars 24 transversely. The transverse partition 28 extends substantially across the entire width of the front compartment 16 and / or the passenger compartment 14.

[0064] Structure 12 is symmetrical. Hereafter, reference will be made to the left side of structure 12; however, this description also applies to the right side.

[0065] The motor vehicle can, for example, be a private motor vehicle or a commercial motor vehicle.

[0066] Figure [Fig. 2] shows a structure 12 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to Figure [1].

[0067] The structure 12 comprises: a passenger compartment 14; a front compartment 16 in front of the passenger compartment 14; a transverse partition 28 longitudinally between the passenger compartment 14 and the front compartment 16. The transverse partition 28 separates the front compartment 16 from the passenger compartment 14. The transverse partition 28 extends vertically. It has a lateral end 34 with a fixing edge 36. The lateral end 34 forms its outer edge.

[0068] The structure 12 further features a front pillar 24 forward of the passenger compartment 14, also called the central cell. The front pillar 24 extends primarily vertically. It is also referred to as the front leg, or "A" pillar. The front pillar 24 comprises an internal bulkhead 32, an external bulkhead (not shown), and a recess between the internal bulkhead 32 and the external bulkhead.

[0069] The structure 12 includes a reinforcement piece 40 for the internal partition 32. The reinforcement piece 40 is attached to the internal partition 32 and to the attachment edge 36. It is welded there using weld beads or spot welds. The reinforcement piece 40 connects the transverse partition to the front pillar. It forms a localized reinforcement that stiffens the internal partition 32. Its presence limits unwanted deformation in the event of a frontal impact. Consequently, the deformation of the structure 12 remains better controlled, which contributes to passenger safety.

[0070] The structure 12 further includes an upper longitudinal member 18 extending along the front compartment 16 from the front pillar 24. The upper longitudinal member 18 is at the top of the front compartment 16. The reinforcing piece 40 is vertically at the level of the upper longitudinal member 18. Thus, it reinforces the structure 12 at the height where the upper longitudinal member 18 mechanically stresses the front pillar 24 during a possible frontal impact.

[0071] The structure 12 includes a shock absorber cup 42 vertically at the level of the reinforcement piece 40. Thus, the reinforcement piece 40 is at the level of a mechanically stressed area.

[0072] The reinforcement piece 40 comprises a front portion 44 extending forward of the transverse partition 28 and a rear portion 46 extending behind the transverse partition 28, also called the front partition. The front portion 44 is transversely against the internal partition 32. The rear portion 46 is transversely against the internal partition 32. Each is fixed to the internal partition 32 by welding or bonding. Thus, the reinforcement piece 40 is extended and allows for the distribution of the forces transmitted by the transverse partition 28.

[0073] The structure 12 further comprises a canopy partition 48. The canopy partition 48 is above the front compartment 16. It extends transversely across the entire width of the front compartment 16. The canopy partition 48 is fixed to the transverse partition 28 and extends longitudinally at the level of the front compartment 16. The reinforcing piece 40 is vertically at the level of the canopy partition 48, which positions it in the area where the canopy partition 48 transmits its forces to the structure 12.

[0074] The front pillar 24 includes a rear edge 50 defining an opening 52 communicating with the passenger compartment 14. The rear edge 50 extends vertically. The reinforcing piece 40 is longitudinally spaced away from the rear edge 50. This configuration optimizes the compactness of the reinforcing piece 40, the mass of the structure 12, and frees up space for the installation of other components.

[0075] The structure 12 comprises a lower longitudinal member 22 extending along the passenger compartment 14, also called the passenger compartment. The front pillar 24 extends from the lower longitudinal member 22. They meet at a corner of the wheel arch. The transverse bulkhead 28 extends to said lower longitudinal member 22.

[0076] Figure 3 shows a front side view of structure 12 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 2.

[0077] The structure 12 includes a fastening interface 54 for the transverse partition 28 to the internal partition 32 of the front pillar 24. The fastening interface 54 is a transverse interface. The fastening interface 54 includes a reinforcing piece 40 transversely between the fastening edge 36 and the internal partition 32. The reinforcing piece 40 is thus arranged transversely between the fastening edge 36 and said internal partition 32. It forms an intermediate reinforcement.

[0078] The structure 12 further includes an upper longitudinal member 18 extending along the front compartment from the front pillar 24. The shock absorber cup 42 is fixed to the upper longitudinal member 18, as is the canopy partition 48. The fixing interface 54 is vertically at the level of the shock absorber cup 42, the canopy partition 48 and / or the upper longitudinal member 18. Thus, the fixing interface 54 forms a reinforced area at the level of a load transmission path.

[0079] The transverse partition 28 includes a vertex 56 vertically at the level of the reinforcing piece 40. The vertex 56 is the highest point of the transverse partition 28. It is a point or a line. Preferably the transverse partition 28 extends beyond the apex 56. Therefore, the reinforcing piece 40 improves the transmission of forces from the transverse partition 28, particularly on its upper part. The risk of the internal partition 32 being punctured by the transverse partition 28 is limited.

[0080] The front pillar 24 is a first front pillar. The structure 12 is generally symmetrical. It further includes a second front pillar (not shown). The transverse partition 28 extends to said second front pillar. The transverse partition 28 extends across the entire width of the front compartment and / or the passenger compartment.

[0081] Figure 4 shows a structural reinforcement piece 40 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 3.

[0082] The structure 12 comprises: a passenger compartment 14; a front compartment (not shown) in front of the passenger compartment 14. A transverse partition 28 spans the passenger compartment 14, demarcating the front compartment. The transverse partition 28 has a vertically extending attachment edge 36. It forms a transverse stop against the reinforcing piece 40. A front pillar 24 is in front of the passenger compartment 14 and has an internal partition 32. The internal partition 32 forms a structural wall.

[0083] The reinforcing piece 40 joins the internal partition 32 to the fixing edge 36, forming an interlayer. The reinforcing piece 40 locally increases the thickness of the internal partition 32, and therefore its strength. This optimizes the strength and mass of the internal partition 32.

[0084] The transverse partition 28, preferably the fixing edge 36, comprises at least one fixing flange 58 attached to the reinforcing piece 40. The fixing edge 36 comprises at least two fixing flanges 58 attached to the reinforcing piece 40 and inclined relative to each other. The fixing flanges 58 are separate and distinct. They are vertically separated from each other. This configuration increases the rigidity of the structure 12. Each fixing flange 58 forms a band of equal, constant width. It is perpendicular to the rest of the transverse partition 28.

[0085] The transverse partition 28 extends substantially over the entire height of the front compartment. It comprises a first vertical thickness, and the front compartment comprises a second vertical thickness lower than the first vertical thickness. The transverse partition 28 comprises an upper plate 74, forming the top; and a lower plate 76. The reinforcing piece 40 is attached to the upper plate 74. The upper plate 74 forms the attachment edge 36.

[0086] Figure 5 shows a reinforcing piece 40 for a motor vehicle structure. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 4.

[0087] The reinforcing piece 40 is a single piece. It comprises a sheet of metal. The sheet metal is cut and stamped. The reinforcing piece 40 includes stiffening ribs 60, openings, and bosses. It generally forms a plate.

[0088] The reinforcing piece 40 includes a flat track 62 extending vertically along the fastening edge (not shown). The fastening edge is attached to the flat track 62 by welding or bonding. The flat track 62 passes vertically through the reinforcing piece 40. The flat track 62 forms a ribbon. The flat track 62 passes through the center of the reinforcing piece 40. It is a central fastening track.

[0089] The flat track 62 is longitudinally located between the front portion 44 and the rear portion 46. It separates them. The front portion 44 is longitudinally longer than the rear portion. The front portion 44 is generally a longitudinal portion, while the rear portion is generally a vertical portion. The front portion 44 extends longitudinally from the rear portion 46.

[0090] The reinforcement piece 40 has a cutout 64. The cutout 64 forms a recess. The cutout 64 is arranged in the front portion 44. The cutout 64 optimizes the mass and compactness of the reinforcement piece 40.

[0091] Figure 6 is a horizontal section of a front pillar 24 of a motor vehicle structure at the level of a reinforcing member. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 5.

[0092] The front pillar 24 is essentially hollow. The front pillar 24 comprises an internal partition 32, an external partition 68, and a recess 70 between the internal partition 32 and the external partition 68. The recess 70 extends vertically. The recess 70 is a principal recess of the front pillar 24. The recess 70 has a transverse thickness of at least 3 cm, preferably at least 5 cm.

[0093] The internal partition 32 comprises a first thickness, for example between 0.65 mm and 0.85 mm. The reinforcing piece comprises a second thickness greater than the first thickness. The second thickness is greater than or equal to 0.80 mm, preferably greater than or equal to 1.00 mm, more preferably greater than or equal to 1.20 mm.

[0094] The front pillar 24 includes a rear edge 50 defining an opening communicating with the passenger compartment 14. The reinforcing piece 40 remains away from the rear edge 50. The rear edge 50 is a fixing rebate. It forms a welding edge of the internal partition 32 and the external partition 68.

[0095] The front pillar 24 optionally includes a reinforcing lining 72 in the recess 70. The reinforcing lining 72 conforms to the external partition 68. The piece of Reinforcement 40 is separate and distinct from the reinforcing lining 72. Reinforcing piece 40 is transversely spaced away from the external partition 68. They are separated at least by the recess 70. Reinforcing piece 40 is outside the recess 70.

[0096] The fixing edge 36 is longitudinally at the level of the recess 70. The lateral end 34 is against the reinforcing piece 40. A flange of the fixing 58 of the fixing edge 36 of the transverse partition 28 fits the reinforcing piece 40.

[0097] A hinge 66 is fixed to the external partition 68. For example, it is fixed to it via a mounting plate. The hinge 66 has a vertical pivot axis. It allows a leaf (not shown), such as a front side door, to be connected to the structure 12. The reinforcing piece 40 is located at the hinge 66. Thus, the reinforcing piece 40 is vertically aligned at the fixing junction formed by the front pillar 24.

[0098] According to an alternative of the invention, the reinforcing piece is in the recess.

[0099] According to an alternative embodiment of the invention, the fixing flange is transversely between the internal partition and reinforcement piece.
