    [0001] The body structure of a motor vehicle with reinforcements for distributing the forces associated with a rear shock absorber of the vehicle The subject of the invention is the body structures of a motor vehicle and more particularly the anchoring points on these bodies of the rear shock absorbers of the vehicle. . With the development of electric or hybrid vehicles, there is more and more frequently vehicle architectures in which the rear floor of the vehicle is raised, that is to say, it is rather at the top of the cutouts passage wheels instead of being at an intermediate height between the bottom of the body and the top of the wheel well. These raised floors allow for example to free up space to place batteries of electric accumulators. However, the requirements of the vehicle impact resistance, including resistance to certain types of rear impact applied to a height normalized with respect to the vehicle, are rather favorable to a low positioning of longitudinal longitudinal structural reinforcements of the vehicle. In order to simultaneously release the space required for the positioning of the batteries, and to meet the rear impact requirements, certain vehicle architectures thus have side members that are locally deported upwards to the rear of the vehicle. Because of this offset, the rear spar, with equal section, is more subject to deformation during impact than a rectilinear equivalent spar. In addition, the rear end of the spar in these architectures is no longer positioned in front of the standardized impact point during rear impact tests. It is then necessary to increase the section and therefore the mass of the side members, and to add additional structural portions for transferring the energy of the impact, the height at which it is applied to the front of the spar.
    [0002] Another problem caused by the elevation of the rear floor of the vehicle is that the shock absorber mounting cups, traditionally attached to the spar, tend to be below the floor of the vehicle and are no longer optimally connected to the upper part of the fund. They can not be in synergy with this upper part of the box in order to dissipate some of the forces transmitted by the damper. The object of the invention is to propose a body structure for a motor vehicle which makes it possible to limit the total mass of the body while at the same time making it possible to ensure a good resistance of the vehicle to the rear impact and to ensure a favorable distribution of the stresses generated by the points of attachment of the dampers, in particular rear shock absorbers of the vehicle. To this end, the invention proposes a body structure of a motor vehicle, comprising a body side superstructure defining on either side of the vehicle two wheel housing slots of the vehicle. The two wheel well housing portions, each housing accommodating at least one wheel, are connected by a floor of the vehicle. The body structure comprises at each of the two wheel well housing portions, a wheel passage piece and at least one rear shock absorber mounting cup joined by its edges to each of the wheel passage pieces. Most often, each wheel-passing part contributes to delimit a housing housing a single wheel of the vehicle, but a housing could, in some embodiments, accommodate several wheels of two neighboring axles. The wheel passage defines at least a substantially oblique surface portion around and beyond the cup edges. The superstructure further comprises a structural sheet integral with an oblique surface portion of the wheel-passing part and integral with a substantially vertical surface portion of the superstructure. Advantageously, the floor is a rear floor of the vehicle, and the wheel arches are wheel wells of the vehicle. According to an alternative embodiment, the oblique surface portion may be horizontal. According to a preferred embodiment, the cup has two first substantially vertical walls, substantially parallel to the structural sheet, each assembled by at least one flange to the wheel well, and at least one of which is located at a distance from the structural sheet that is less than or equal to the largest dimension of the cup. The structure may further include a rear reinforcing beam, the body side superstructure rising above the spar. The cup may be assembled to the spar by means of a beam riser and connecting the spar and the cup. Preferably, the wheel passage portions are offset vertically upwards relative to the spar.
    [0003] Preferably, the damper attachment cup is assembled to the lateral superstructure, and assembled to a longitudinal reinforcement spar by means of a riser part connecting the cup and only a portion of the spar. Only a portion of the spar means only a portion of the spar length in the longitudinal direction of the vehicle. The extension piece is of width, measured in a longitudinal direction of the vehicle, substantially equal to that of the cup. The maximum width of the extension piece may be typically between 0.9 and 1.3 times the maximum width of the cup, the term width being used here to designate a dimension along the longitudinal axis of the vehicle. The raiser part positions the cup above the spar, that is to say in a position offset vertically relative to the spar. Advantageously, the assembly points between the extension piece and the spar are substantially aligned in a vertical direction with an edge of the cup. Preferably, the vertical offset between the bottom of the cup and the nearest point of the spar is at least equal to the height of the cup, the vertical offset between the bottom of the cup and the nearest point of the spar can be, for example, between two and ten times the height of the cup. By height means a dimension measured in a vertical direction of the assembled part in the vehicle. The extension piece thus has a width that transmits the vertical forces between the cup and the spar, without closing the entire width of the vertical space between the floor and the spar. It is thus possible with a room consuming little material, transfer to the spar the vertical forces of the damper, and nevertheless keeps a good lateral accessibility to the elements between the wheels and under the floor. Advantageously, the floor is placed above an upper limit of the wheel-opening openings visible on the bodywork outside the vehicle. According to a particularly advantageous embodiment, several parallel structural plates are disposed on either side of the cup relative to the longitudinal axis of the vehicle. At least one structural sheet may be part of a structure portion forming a four-sided box and a bottom of which one side is a substantially vertical surface portion of the superstructure and whose bottom is a portion of the wheel well .
    [0004] According to an advantageous embodiment, the damper attachment cup is positioned to be substantially in the horizontal extension of the rear floor. For example, the minimum height of the rear floor can be between the assembled height of the bottom of the cup and a maximum height of an edge of the cup. Advantageously, the extension piece has a beam geometry substantially U-section, the axis of the beam being oriented substantially vertically, at least two parallel edges of the U-shaped section being placed in the extension of the first two substantially vertical walls of the cup. The first two parallel edges of the U-section are preferably assembled, for example by welding, to the first two substantially vertical walls of the cup. The U-shaped section can be scalable between the attachment point (s) to the spar and between the assembly areas between the cup and the extension piece. For example, the U may not be entirely symmetrical, and the height of the edges of the U may increase between the spar and the cup. At the level of the assembly areas with the cup, the height of the U may be chosen sufficient so that the edges of the beam completely surround, at least in a plane of cross section of the beam, the first two walls of the cup. The first two walls of the cup can be fully doubled, on their vertical portion, by two first edges of the U-beam of the extension piece.
    [0005] According to one embodiment, the cup has at least a third substantially vertical or oblique side wall, joining the first two walls, and the cup has a substantially horizontal bottom wall joining the first two walls and placed in the continuity of the third wall . By oblique means here a direction which is neither vertical nor horizontal, the vehicle being placed in a usual driving position on a flat road. According to a preferred embodiment, the open side of the U-shaped section of the extension piece is turned towards the lateral side of the vehicle which is outside the vehicle, and the third side wall of the cup is on the outside of the vehicle, so the open side of the U. The cup may not have a fourth wall, or may have a fourth substantially vertical wall facing the third wall. The first, second, third and fourth walls may each be connected to the bottom wall of the cup by a curved wall portion in order to limit the stress concentrations at the transition zones between the bottom wall of the cup and the at least one of the side walls of the cup, each preferably comprising at least one vertical wall portion. According to a preferred embodiment, the height of the fourth wall is less than the height of the third wall. Other embodiments are of course conceivable. The third and fourth wall of the cup may be of substantially equal height, or the uppermost wall may taper the cup from the interior side to the vehicle. The open side of the U can be turned towards the inside of the vehicle, and / or the base of the U can be in continuity with the third wall. The bottom wall of the cup can typically be drilled to accommodate, for example, a screw for fixing the damper.
    [0006] A reinforcing piece can be assembled on the bottom of the cup to increase the flexural strength of the bottom of the cup. Ribs can be made by stamping to connect in a curved path the bottom of the cup and at least one of the substantially vertical walls of the cup, so as to stiffen the cup overall and facilitate the transmission of forces between the bottom of the cup where is assembled the end of the damper, and the walls of the cup connected to the sides of the U-beam. Advantageously, the first two walls and the third wall can be assembled to the wheel-passing part by welding two first flanges of the first two walls, and welding a third flange of the third wall, the flanges being folded to be substantially in a common plane with an inner rim of an opening of the wheel well. According to a preferred embodiment, the cup is open upwards, that is to say that the damper bears against the bottom of the cup while remaining outside the cup. The cup is preferably assembled to the side superstructure so that the opening of the cup is flush below at an opening of the wheel well. This orientation of the cup makes it possible to assemble the cup by three of its vertical walls to the U-shaped beam and makes it possible to assemble the cup by rims of the cup, to the wheel-passing piece. This optimizes the distribution of the forces of the damper between the U-beam and the wheel well. According to an advantageous embodiment, the wheel-passing part has a lower edge which is level with an edge of the floor and which is assembled at this floor edge.
    [0007] The cup may have at least a third substantially vertical or oblique lateral wall joining the two first walls, have a substantially horizontal bottom wall joining the first two walls and placed in the continuity of the third wall, and may be assembled by flanges of first two walls and the third wall to the wheel arch piece. Advantageously, the cup is also assembled to the wheel-passing piece along a rim which runs along the bottom wall of the cup, or along a rim which runs along a fourth wall of the cup. According to an advantageous embodiment, the third wall of the cup may be doubled by a central portion of the U-beam, the central portion being the central strip of the beam joining the two strips forming the sides of the U of the beam. According to another embodiment, it is a rim of the bottom of the cup, that is to say the fourth wall, or it is a rim of the fourth wall which is assembled (e) to the central portion of the U-beam thus surrounds the cup on at least two faces, and preferably on three sides. The faces concerned are the first wall, the second wall, and one of the third and fourth walls. The cup may also be assembled to the wheel-passing piece along a rim which runs along either the bottom wall of the cup or a fourth wall opposite the third wall and of height less than the height of the third wall. .
    [0008] According to a preferred embodiment, the extension piece is assembled to the cup in at least several different points of each of the first two walls of the cup. Preferably, the extension piece is assembled to the cup in at least three points of each of the first two walls of the cup. According to an advantageous embodiment, the raising piece may further be assembled directly to the wheel-passing part along certain portions of the inner rim of the opening of the wheel-passage piece.
    [0009] The invention also proposes a motor vehicle comprising a body side superstructure defining on both sides of the vehicle two portions of the right and left wheel housing housing of the vehicle. The two right and left wheel-passing housing portions are connected by a floor of the vehicle. The vehicle comprises at each wheel housing slot portion, a wheel passage piece and at least one damper attachment cup assembled to each of the wheel arch pieces. The wheel passage defines at least a substantially oblique surface portion around and beyond the cup edges. The superstructure further comprises a structural sheet integral with an oblique surface portion of the wheel-passing part and integral with a substantially vertical surface portion of the superstructure.
    [0010] Other objects, features and advantages of the invention will appear on reading the following description, given solely by way of non-limiting example, and with reference to the appended drawings, in which: FIG. 1 is a simplified view in FIG. 2 is a top view of the body structure portion of FIG. 1; FIG. 3 is a perspective view of a few characteristic elements of FIG. another body structure according to the invention.
    [0011] In Figures 1, 2 and 3, the x axis represents a longitudinal axis of the vehicle, the y axis represents a transverse axis of the vehicle and the z axis represents a vertical axis. The structures shown in FIGS. 1, 2 and 3 are present at least twice on the vehicle, each time having two symmetrical structures with respect to an axis parallel to the x axis and passing through the middle of the vehicle. As illustrated in Figures 1 and 2, a body structure 1 of a motor vehicle (not shown) according to the invention comprises a longitudinal member 2 disposed longitudinally along the vehicle and extending at least partially to the rear of the vehicle. The structure comprises a substantially vertical portion 3 of a lateral superstructure 9 in which is provided a wheel passage opening 29 for mounting a wheel on the vehicle below the lateral superstructure 9, and comprises a rear floor 5 which is raised , that is to say placed vertically above the longitudinal members 2. The rear floor 5 is not necessarily overhanging with respect to the longitudinal members 2 but is in any case vertically offset upwards relative thereto. The floor 5 is connected to the lateral superstructure 9 by a wheel-passing part 7 defining at least one oblique surface portion 30 and which is assembled, on the inside of the vehicle (with respect to a transverse direction of the vehicle), on the floor 5, and which is assembled, on the outside of the vehicle, to the lateral superstructure 9.
    [0012] The lateral superstructure 9 comprises at least a substantially vertical portion 3, which may for example comprise an outer portion of quarter end 3a, comprising an outer finish sheet, an inner quarter portion 3c on which are assembled various elements inside the vehicle, and a intermediate quarter portion 3b connecting the outer quarter portion 3a and the inner quarter quarter portion 3c so as to leave a gap between the inner and outer portions to facilitate the assembly of various elements on the inner portion 3c. The intermediate portion 3b defines a radially outer portion of a wheel housing 4 inside which a wheel of the vehicle can be inserted through the opening 29. The remaining depth (along the y axis) 4 of the wheel housing 4 is defined by the wheel-passing part 7. On the wheel-passing part 7 is assembled a damper fixing cup 10. An opening 8 is formed in the wheel-passing part 7 below which the cup 10 is assembled beneath the wheel-passing part 7, the edges of the cup 10 bearing on the wheel-passing part 7 and being assembled thereto around the opening 8. The bottom 15 of the cup 10 is offset downwardly relative to the wheel part 7. The bottom 15 may be pierced with a bore 16 for assembling the end of the rear shock absorber (not shown)
    [0013] This bottom 15 may optionally be doubled with a reinforcing sheet (not shown). The cup 10 is connected to the spar 2 by an extension piece 20 which thus connects the lateral superstructure 9 to the spar 2. The raising piece 20, as can be seen in the top view of FIG. 2, has a section of FIG. U-beam, the two arms 17, 18 of the U extending along the y-axis transverse to the vehicle, and the base 19 of the U extending along the x-axis. The extension piece 20 is welded or otherwise assembled on the spar 2, and is also integral, by the portions forming the arms 17, 18 of the U, with the cup 10. The raising piece 20 surrounds, as can be seen on Figure 2, the cup 10 which has a substantially rectangular or square contour. The cup 10 has a first cup wall 11 and a second cup wall 12 substantially parallel to the transverse axis y. The cup 10 has a third cup wall 13 bordering the cup on the side outside the vehicle (with respect to the y axis) and a fourth wall 14 which may optionally be of zero height and which borders the cup 10 on the inside of the vehicle . There are of course in Figure 2 elements common to Figure 1, the same elements being represented by the same references. To lighten the design, the floor 5 and the spar 2, however, have not been shown in Figure 2. The extension piece 20 has a U-shaped section, this section comprising a first parallel edge 17 and a second parallel edge 18 all two parallel to the transverse axis y of the vehicle (or at least forming an angle symmetrical about this axis y transverse to the vehicle) and has a third edge 19 forming the base of the U-shaped section and which is substantially parallel to the direction longitudinal x of the vehicle.
    [0014] The first and second walls of the cup are substantially vertical or end with a substantially vertical portion. The first edges, second edges and base edges of the U-shaped section of the extension piece 20 also form substantially vertical planes. The first and second parallel edges of the extension piece 20 are assembled to the first and second walls respectively 11 and 12 of the cup 10. The third edge or base edge of the U-section is here assembled to the fourth wall the cup located on the inside of the vehicle. Embodiments may be envisaged in which this third edge of the extension piece 20 is assembled to the third cup wall located on the outside of the vehicle. The cup 10 is assembled to the wheel-passing part 7 by tabs 27 along the edges of the first, second, third and fourth walls of the cup 10. The raising piece 20 may also have one or more tabs 28 for securing the raising piece 20 with the wheel-passing piece 7 possibly by interposing between a tongue 28 and the wheel-passing part 7, a tongue 27 of the cup 10. As can be seen both in FIGS. 1 and 2, the body structure 1 of a motor vehicle also comprises a structural plate 22 substantially square shape. The structural sheet 22 comprises at least one substantially vertical portion of efforts 22a, which is substantially parallel to the first wall 11 and the second wall 12 of the cup 10, as well as to the first parallel edge 17 and to the second parallel edge 18 of the extension piece 20. All these vertical portions 22a, 11, 12, 17, 18 of parts of the body structure are all parallel to a geometric plane 21 vertical and transverse to the vehicle. The plane 21 is shown in FIG. 3, and has as axes the axes y, z. It is possible to envisage variant embodiments in which the plane 21, common to the structural plate 22, to the first and second walls 11, 12 of the dish 10, to the first and second parallel edges 17, 18 of the U-shaped section of the piece of raises 20, is not strictly vertical, or is not strictly transverse to the vehicle. Preferably, the plane 21, however, remains inclined by less than 10 ° with respect to the vertical and preferably remains inclined by less than 5 ° with respect to the vertical.
    [0015] The inclination of the plane 21 with respect to the y axis may depend on a local curvature of the spar 2 on which the raising part 20 is assembled. The plane 21 may then be perpendicular to the spar. Embodiments may be envisaged in which the first and second edges 17, 18 of the extension piece 20 are not parallel but convergent or divergent (in view on a cross section of the beam forming the extension piece). The first and second cup walls 11, 12 can then be convergent or divergent, so as to assemble the first cup wall at the first edge of the extension piece, and the second cup wall at the second edge of the extension piece. A structural plate 22 may then be positioned parallel to that of the first and second cup walls 11, 12 which is closest to the structural plate 22, or may be in a plane transverse to the vehicle.
    [0016] The structural sheet 22 is placed close to at least one of the first and second walls of the cup, so as to be able to take back part of the vertical forces transmitted by the damper to the cup 10 and then to the cup 10. 7. The structural sheet 22 may comprise a portion 22b also vertical and substantially perpendicular to the portion 22a of effort recovery. The portion 22b is assembled to the inner quarter portion 3c and makes it possible to transfer the vertical forces received by the effort recovery portion 22a, towards the inner quarter portion 3c. The structural sheet 22 is also integral with the wheel-passing part 7, on at least a portion of the lower edge of the force-absorbing portion 22a. A tab (not shown) for assembling the structural plate 22 may be at an angle with the portion 22a and be assembled on the oblique surface portion 30 of the wheel-passing part 7. According to another variant embodiment, the portion 22a of recovery efforts can be assembled in the lower part to a substantially vertical portion 31 of the wheel-passing part 7, bordering the wheel-passing part 7 in a plane direction substantially perpendicular to the inner quarter portion 3c. According to yet another embodiment that can be combined with the preceding, the structural sheet 22 can be assembled by its portion 22a to a third part (not shown) comprising a portion of sheet also parallel to the plane 21 and being placed in the extension of the effort recovery portion 22a, this third piece also being integral with the wheel-passing part 7. Thus, the vertical forces transmitted by the rear shock absorber (not shown) to the cup 10 can be transmitted by the edges of the cup 10 through the extension piece 20 to the spar 2 and may also be partly transmitted by the cup 10 to the wheel-passing part 7, then by the structural plate 22, then to the lateral superstructure 9 whose direction is favorable to the recovery of the vertical forces. It is possible to envisage variant embodiments in which the wheel-passing part 7 is not oblique but is horizontal.
    [0017] In order to promote the transfer of the vertical forces towards the upper part of the body structure, in particular towards the lateral superstructure 9, the structural sheet 22 is situated close to the cup 10, typically at a distance less than the largest dimension of the body. cup itself, this minimum distance being respected both for the distance along the x-axis and for the distance along the y-axis. According to an advantageous embodiment, the structural plate 22 is assembled to the wheel-passing part 7 so that the total assembly length along the y-axis between the structural plate 22 and the wheel-passing part 7, at least equal to half, and preferably two-thirds, of the minimum distance along this axis y between one of the side walls of the cup and a substantially vertical surface portion of the superstructure, for example the quarter portion interior 3c. In certain particularly advantageous embodiments, the total assembly length is even greater than this minimum distance, so that a portion of the structural sheet 22 runs along at least a portion of a side wall 11, 12 of the This improves the recovery by the structural sheet of the forces transmitted by the cup 10 to the wheel-passing part 7. The structural plate 22 can be assembled to the wheel-passing part 7 by tongues parallel to the portion 30 of oblique surface of the wheel-passing part 7, or by a portion of the wheel-passing part 7 which, on the contrary, is vertical and assembled on a vertical portion of the structural sheet 22. The structural sheet 22 may moreover result from an assembly of several parts each comprising at least a substantially flat portion parallel to the axis 21, all the portions parallel to the axis 21 being assembled to form a force transfer plate secured to both the wheel-passing part 7 and integral with the portion 3 of the lateral superstructure 9. In order to further improve the transfer of the vertical forces of the wheel-passing part 7 in the vicinity from the cup 10 to the lateral superstructure 9, other vertical force transfer elements may be added which are integral with both the wheel-passing part 7 and the lateral superstructure 9. These elements preferably comprise a or several vertical planes connecting the wheel-passing part 7 and the lateral superstructure 9. These vertical planes are preferably, at least for some, parallel to the plane 21 and parallel to the first and second walls 11, 12 of the dish 10. At at least one of these parallel vertical planes is in the vicinity of the cup 10, i.e. at a distance along the x-axis and at a distance along the y-axis which is smaller than the larger size of the cup. Thus, in FIG. 2, can be seen a belt reel locker 23 comprising a front piece 24 and a rear piece 25. The rear piece 25 comprises a bottom portion 25c contiguous to and fixed on the inner portion 3c and comprises two side walls 25a and 25b parallel to the plane 21 of force transmission. The rack 23 also comprises a front piece 24 comprising a front wall 24c parallel to the rear wall 25c and comprising two side walls 24a and 24b assembled on the side walls 25a and 25b of the rear piece 25. The front piece 25 further comprises assembly tabs 26 for securing the bottom of the front piece 24 with the wheel-passing piece 7. The assembly tabs 26 are longer than at least half the length along the y-axis of the side walls 24a and 24b, so as to enable the vertical forces of the wheel-passing part 7 to be effectively transmitted to the assembly of the furling rack 23 and then to the lateral superstructure 9.
    [0018] The reel bin 23 is not visible in Figure 1 because it is in front of the sectional plane of this figure. Figure 3 is a perspective representation of a body structure similar to that shown in Figures 1 and 2. In Figure 3 are found elements common to Figures 1 and 2, the same elements being designated by the same references. In particular, FIG. 3 shows a U-section beam-shaped riser piece 20, the edges of the U surrounding the side walls of a damper attachment plate. FIG. 3 does not show the wheel-passing part 7, in order to better see the contours of the cup 10 and of the extension piece 20. On the other hand, FIG. 3 shows the structural sheet 22 in the form of a bracket and a belt retractor bin 23 disposed this time towards the rear of the vehicle relative to the structural plate 22.
    [0019] In Figure 3, the floor 5 has not been shown but can be seen a rear floor crossbar 6 indicating the assembly height of the floor. Thanks to the body structure of the invention, one can have a space under the rear floor of the vehicle while keeping a good resistance to rear impact of the vehicle through a low position of the longitudinal reinforcing beams. The raising piece 20, which represents a reduced material cost, makes it possible to transmit the forces of the rear shock absorber (not shown) to the reinforcing spar 2. The force transfer elements 22, 23 make it possible to transmit the forces of the rear shock absorber (not shown) to the lateral superstructure 9. The invention is not limited to the embodiments described and can be declined in many variants. It is possible to envisage a body structure comprising an extension piece 20 as described above and not including the structural plates 22. It is possible to envisage a body structure in which the cup 10 would be connected by a piece other than the U-shaped beam described. previously with the spar 2, and having on the contrary one or more structural plates 22 and / or a box-shaped force transfer element such as the reel rack 23. The preferential plan 21 for taking up the vertical forces could not not be parallel to the y axis transverse to the vehicle. The cup could be assembled so that the bottom of the cup is turned towards the top of the vehicle. The riser piece 20 in the form of a U-shaped beam could have the opening of the U turned towards the inside of the vehicle. The extension piece 20 could have a shape surrounding the cup 10 in the upper part, and evolve to a beam of different section in the lower part, for example to a closed rectangular section or a closed triangular section. The outline in top view of the cup itself could be triangular or trapezoidal. The portion of the beam surrounding the cup may have a closed section surrounding all the side walls of the cup. The level of the rear floor may not correspond to the bottom of the opening of the wheel passage 7 accommodating the cup 10. Removable assemblies could replace all or part of the welded joints connecting the spar 2, the extension piece 20 , the cup 10, the wheel-passing part 7, the structural plate 22, the front part 24 and the rear part 25 of the belt-winder bin 23.
