    [0001] BACKGROUND OF THE INVENTION The invention relates to a central part of the underbody of a structural body of a motor vehicle, intended to delimit the lower part of a passenger compartment of the vehicle and to be interposed. between front and rear structural parts. The invention also relates to a structural body of a motor vehicle comprising such a central portion of the base. State of the art Currently, the body of the motor vehicle body is dedicated to a given motorization selected from the thermal or electrical. For the same platform of a vehicle, it is therefore necessary to design and manufacture a base associated with the thermal engine and another substructure, different, associated with the electric motor.
    [0002] For thermal engines installed in a structural unit before the body, the fuel tank is located under the floor of the rear structural unit. The floor of the central portion of the base is a floor located at such a height that it extends below the flaps that line the longitudinal edges of the central portion.
    [0003] For electric vehicles on the other hand, the bases are dedicated solely to this type of engine and can not be used in the context of a thermal engine. In particular, the central portion of the base comprises a floor arranged in two zones at two different heights: a high rear area that allows a volume under the floor to receive a storage battery of electrical energy for supplying electricity to the engine and a low front zone which delimits, on the side of the passenger compartment, a volume adapted to receiving the feet of the occupants of the vehicle. This problematic of having to constitute a pair of bases respectively dedicated to the thermal motorization and to the electric motorization envisaged on the same platform, is reflected for each sought-after length of vehicle: it is necessary to constitute as many such pairs of bases as of sought lengths the vehicle for the same platform, for example such a pair in the case of a vehicle with two seats and another such a pair in the case of a vehicle with four seats.
    [0004] OBJECT OF THE INVENTION The object of the present invention is to provide a central part of the underbody structural body of a motor vehicle that overcomes the disadvantages listed above. In particular, an object of the invention is to provide such a central part of the base and a structural box which allow to manage a mix between the electric motor and the thermal motor for the same platform and which facilitates the adaptation in length of the vehicle, limiting simplicity, cost and flexibility.
    [0005] This object can be achieved by means of a central part of the underbody structural body of a motor vehicle, intended to delimit the lower part of a passenger compartment of the vehicle, comprising: - a set of first interface elements for mounting on the central part base of components of a first type associated with the operation of a vehicle drive heat engine intended to be mounted on a rear structural part of the structural body integral with the central part of the base, and a set of second elements interface for mounting on the central part of the substructure of components of a second type associated with the operation of an electric drive motor of the vehicle to be mounted on said rear structural part. According to a particular embodiment, the set of first interface elements and the set of second interface elements are arranged in the same area of the central part of the base in a longitudinal direction of the vehicle. The length of the central part of the underbody in the longitudinal direction can in particular be configured so that the central part of the underbody allows to receive two seated places offset in a lateral direction of the vehicle, the central part of the base constituting a first type of central part. underbody. The set of first interface elements may be arranged in a first zone of the central subbase in the longitudinal direction and the set of second interface elements may be arranged in a second zone of the subbase core section. in the longitudinal direction, the first and second zones being distinct.
    [0006] According to another particular embodiment, the length of the central portion of the base in the longitudinal direction is configured so that the central portion of the base allows to receive four seats divided into two rows offset in the longitudinal direction and each including two seats seats offset in the lateral direction of the vehicle, the central portion of the base constituting a second type of central portion of the base, in particular configured to include the central portion of the base of the first type.
    [0007] The rear edge of the central base portion of the first type and the rear edge of the central sub-base of the second type can be equipped with the same interface element for connection to the rear structural part of the structural body.
    [0008] The first and second zones are preferably offset with respect to one another in the longitudinal direction and constituted respectively by a rear zone of the central part of the underbody and by a front zone of the central part of the underbody.
    [0009] According to a particular embodiment, the set of first interface elements comprise elements for mounting, under a floor of the central part of the base, a fuel storage tank for supplying the driving heat engine. and the members associated with the operation of said reservoir and the set of second interface elements comprise elements for mounting, under the floor of the central part of the base, a storage battery of the electrical energy intended to supply the electric motor drive and the members associated with the operation of said battery.
    [0010] Along each of its longitudinal edges, the central portion of the base may include a flap and the floor of the central portion of the base may be mounted in the upper part of the flap so as to provide a space under the floor, the opposite side to the passenger compartment in a vertical direction, said space can indifferently accommodate either said tank or the battery. A structural body of a motor vehicle may include such a central part of the underbody and a rear structural part integral with the rear edge of the central part of the base, the rear structural part indifferently bearing either the drive engine associated with the components mounted on the part base unit via the set of first interface elements or the electric drive motor associated with the components mounted on the central part of the underbody via the set of second interface elements. The structural box may comprise a front structural part including at least one front spar, the assembly being arranged so that the central part of the base is interposed between the front structural part and the rear structural part in the longitudinal direction, and the structural box may comprise at least one structural part ensuring a recovery of efforts and / or a transmission of forces on the one hand between the front spar and at least one flap arranged along a longitudinal edge of the central part of the base, on the other hand between the front spar and a longitudinal tunnel of structure of the central part of the plinth centered in the width of the central part of the base.

    [0012] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION The description which follows is made with reference to an orthonormal reference (X, Y, Z) conventionally associated with a motor vehicle, in which X is the longitudinal longitudinal direction of the front-rear of the vehicle, Y is the right-left transverse direction which is horizontal and perpendicular to X, and Z is the vertical direction jointly perpendicular to the X and Y directions. These directions can be considered as related to the structural body of the vehicle and thus also to the motor vehicle. The central part of the underbody 10 of the structural body of a motor vehicle, in particular visible in FIGS. 2 to 7 and intended to delimit the lower part of a passenger compartment of the vehicle, comprises: a set of first interface elements allowing the mounting on the central part of the underbody 10 of components of a first type associated with the operation of a drive heat engine 11 of the vehicle intended to be mounted on a rear structural part 100 of the structural box secured to the central part of the underbody 10, and a set of second interface elements for mounting on the central part of the base 10 of components of a second type associated with the operation of an electric drive motor 12 of the vehicle intended to be mounted on said rear structural part 100. With reference to FIGS. 2 and 3, which relate to a first type of central portion of the underbody 10 Ini further, the set of first interface elements and the set of second interface elements may, in this variant, be arranged in the same single zone of the central portion of the base 10 in the longitudinal direction X. This single zone is marked A in FIGS. 2 and 3. In order to form the first type of subfrase 10, the length L1 (FIG. 6) of the central subbase 10 in the longitudinal direction X is preferably configured so that the central part of the base 10 can receive two seats staggered together in the lateral direction Y.
    [0013] Referring now to FIGS. 4 and 5, which relate to a second type of central sub-base 10 defined below, the set of first interface elements are arranged in a first zone B of the central base portion 10 in the longitudinal direction. X and the set of second interface elements are arranged in a second zone C of the central part of the base 10 in the longitudinal direction X, the first and second zones B and C being distinct. In the foregoing, whether for the single zone A mentioned for the first type of subbase 10 and for the first and second zones B and C mentioned for the second type of subbase, a "zone" s is preferably intended to be a part of the central sub-base 10 delimited over a fraction of the length of the central portion 10 in the longitudinal direction X and at the same time over the entire width of the central portion 10 in the direction Lateral Y. To form the second type of subfrase 10, the length L2 (FIG. 7) of the central sub-base 10 in the longitudinal direction X is preferably configured so that the central sub-base 10 can receive four seats divided into two rows offset between them in the longitudinal direction X and each including two seats staggered between them in the lateral direction Y of the vehicle.
    [0014] Preferably, the second type of basement core portion 10 is configured to include the basement core portion 10 of the first type. In particular, it is the fraction before (in the longitudinal direction X) of the central portion 10 of the second type which is identical to the central portion 10 of the first type, the central portion of the second type further including an additional rear fraction. These rear and front fractions are in one piece to finally form a central portion of the second monobloc type. In a structural box including a central part of the underbody of the second type, this additional rear fraction ensures the connection and the cohesion, for the transmission and collection of forces from one part to the other, between the central part. underbody 10 according to the first type and the rear structural part 100.
    [0015] The solution described here makes it possible to take into account, for the central part of the underbody 10 of the same vehicle platform, the constraints related to the thermal motorization and the electric motor for a vehicle which is indifferently of the type with 2 places or 4 places. In other words, each central part of the substructure described here makes it possible to be indifferently used selectively in the context of a use involving a thermal motorization via the heat engine 11 and in the context of a use using an electric motor via the electric motor 12. The design of the central part of the substructure of the platform concerned makes it possible to receive all the interfaces of the components for the heat engine (mainly the fuel tank and the associated members) as well as all the components for the engine. the electric motor (mainly the battery and the associated organs). In addition, the length of the central floor, between the length L1 and L2, allows to move from a platform for 4-seater vehicle to a 2-seater vehicle or vice versa. The same platform makes it possible to adapt and take into account the diversity between the two-seater configuration and the four-seater configuration as well as the type of motorization between the electrical nature and the thermal nature.
    [0016] According to one embodiment, the rear edge 13 of the central base portion 10 of the first type and the rear edge 14 of the central portion of the second type of base are equipped with the same interface element for connection to the part. structural rear 100 of the structural fund. In other words, the interface element of the rear edge 13 of the first type of subfrase 10 providing connection to the rear portion 100 of the structural box and the interface element of the rear edge 14 of the second type of part. The base unit 10 connecting to the rear part 100 of the structural box is identical. As illustrated in FIGS. 4 and 5, the first zone B and the second zone C are offset with respect to each other in the longitudinal direction X and constituted respectively by a rear zone of the central part of the underbody 10 and by a front zone of the central part of the underbody 10, seen in the longitudinal direction X. The set of first interface elements comprise elements making it possible to mount, under a floor 17 (FIG. 8) of the central part of the base 10, a tank 16 for storing a fuel intended to supply the heat engine with 11 and the members associated with the operation of said reservoir 16 and the heat engine 11. The set of second interface elements comprise elements for mounting, under the floor 17 of the central portion of the base 10, a storage battery 15 electrical energy for supplying the electric drive motor 12 and the members associated with the operation of said battery 15 and the electric motor 12. In the second type of central portion 10, the battery 15 for storing electricity for supplying the electric drive motor 12 in the electric version is therefore not mounted in the zone intended to receive the fuel tank 16 of the thermal version. The space left free by the tank 16 in the first zone B when the electric motor is used is vacant. This space is dimensioned and structured to absorb the energy transmitted during different shocks (front, rear and post), without deforming in order to meet the structural integrity criteria. Along each of its longitudinal edges, the central basement portion comprises a lip 18 (Figures 8 and 9). Preferably, the central portion of the base 10 thus comprises the flap 18 which is an elongated structural element, oriented in the longitudinal direction X, which belongs to the structural body and is implanted at one of the longitudinal edges of the right or left of the underbody. The flap 18 may be in the form of a hollow reinforcing body, of tubular shape with a closed contour section oriented in the longitudinal direction X. The flap 18 defines a tubular cavity 19. The floor 17 of the central part of the base 10 is mounted in the upper part of the flap 18 so as to provide a space 20 under the floor 17, the opposite side to the passenger compartment in the vertical direction Z, said space 20 can indifferently accommodate either said fuel storage tank 16 is the battery 15. The structural body of a motor vehicle, illustrated for example in FIG. 9, comprises a central base portion 10 described above and a rear structural part 100 integral with the rear edge 13, 14 of the the central part of the base 10, the rear structural part 100 indifferently bearing either the driving heat engine 11 associated with the components mounted on the central part of the base 10 via the set of first interface elements or the electric motor of drive 12 associated with the components mounted on the central part of the base 10 via the set of second elements interface ts. The structural box comprises a front structural part 200 including at least one front spar 201, the assembly being arranged so that the central part of the base 10 is interposed between the front structural part 200 and the rear structural part 100 in the longitudinal direction X The structural box comprises at least one piece of structure 202 ensuring a recovery of forces and / or a transmission of forces on the one hand between the front spar 201 and at least one of the flaps 18 arranged along a longitudinal edge of the central portion of the base 10, on the other hand between the front spar 201 and a longitudinal tunnel structure 21 of the central portion of the base 10 centered in the width of the central portion of the base 10 and oriented in the longitudinal direction X.
    [0017] Said at least one piece of structure 202 comprises a connecting element providing a connection between the structural part 202 and the flap 18 configured so as to achieve a recovery of longitudinal forces by the structural part 202 from the flap 18 and / or a transmission of longitudinal forces from the structural part 202 to the flap 18, in particular in the event of a front or rear impact applied to a vehicle equipped with the central part of the underbody 10. In FIG. 9, the arrow F1 represents the transmission longitudinal forces from the structural part 202 to the flap 18 in the event of impact front or front applied to the front portion 200 of a vehicle equipped with the central portion of the base 10. Said at least one structural part 202 comprises a connecting element providing a connection between the structural part 202 and the longitudinal structure tunnel 21 configured so as to achieve a long-term recovery of forces tudinal by the structural part 202 from the longitudinal tunnel 21 and / or a transmission of longitudinal forces from the structural part 202 to the longitudinal tunnel 21, especially in case of front or rear impact applied to a vehicle equipped with the part central bedrock. In the figure, the arrow F2 represents the transmission of longitudinal forces from the structural part 202 to the longitudinal tunnel 21 in the event of a front or front impact applied to the front portion 200 of a vehicle equipped with the central part of the base 10.30. A similar arrangement can be provided on each right and left side of the structural box in its front portion 200, using a right front spar 201 and using a left front spar 201 shifted in the lateral direction Y, belonging to the front part 200, said at least one structural part 202 providing a cooperation as previously defined between the two front longitudinal members 201 right and left and the right and left sidelaps 18 respectively. Said at least one structural part 202 may include in particular a front cross member connecting the rear ends of the two front longitudinal members 201 and parts connecting this cross member to the front ends of the two flaps 18 and the longitudinal tunnel 21. The longitudinal tunnel structure 21 is delimited preferably by a profile-shaped piece attached to the floor 17 of the central part of the underbody 10 so as to be oriented in the longitudinal direction X and to delimit, in combination with the floor 17, a hollow reinforcing body of tubular form , having a section having a closed contour, disposed above the floor 17. In other words, the hollow body defined by the longitudinal tunnel 21 is arranged on the side of the passenger compartment, avoiding in a very simple and inexpensive way all problems related to to corrosion. By "hollow body", it is preferably understood that it is a body delimiting a cavity or volume, closed or partially open to the outside. The delimitation of such cavities or such volumes greatly contributes to the stiffness in compression, flexion, torsion, shear, of the structural body part, and allows to meet the functional specifications conventionally suffered by a body part. Each reinforcing hollow body is configured (sizing, orientation, shape of the cutting section, spatial organization, etc.) so as to absorb a majority of the forces (compression, torsion, shear) experienced by the central part of the base. 10 in case of impact (front, rear, side, etc ...) applied to a vehicle equipped with this part 10. It should also be noted that the term "reinforcement" preferably means that the hollow body thus defined supports the most, if not all, of the inputs and outputs of mechanical forces experienced by the central part 10 concerned, in addition to the flaps 18.
