    [0001] FIELD OF THE INVENTION 1. Field of the Invention The present invention relates to a front-end module for a motor vehicle and, more specifically, to a structure for a motor vehicle. support adapted for said front panel module. STATE OF THE ART In general, within a motor vehicle, a front-end module is a structural element intended to contain a plurality of devices necessary for the operation of the motor vehicle, such as projectors or heat exchangers. At the end of the production of a front-end module, it can be directly assembled on the motor vehicle, in particular with elements of the chassis of the motor vehicle, such as the side members. The front panel module can also be mounted on the motor vehicle by assembling with a bumper or a front shield.
    [0002] In known manner, the front-end module comprises a support structure for receiving the devices necessary for the operation of the motor vehicle and a bumper beam to protect said devices in a frontal collision between a pedestrian and the motor vehicle. The support structure of the front-end module comprises different pieces fastened together.
    [0003] Thus, the support structure comprises a bottom rail, side posts for said lower rail, an upper rail adapted to be attached to the top of the side posts and reinforcing arms attached to the ends of the upper rail and / or on the side posts .
    [0004] In general, such a support structure is entirely made of a resistant material, such as steel, in order to comply with the standards imposed by the regulations on motor vehicle safety in a frontal collision between a vehicle and a vehicle. pedestrian and a motor vehicle. However, such a support structure represents a significant weight within the motor vehicle which generates a high fuel consumption and a high level of carbon dioxide (CO2) emissions.
    [0005] Therefore, it is necessary to improve the design of a support structure of a front-end module according to the state of the art to optimize the operation of the motor vehicle, while respecting the standards. relating to automotive safety regulations.
    [0006] OBJECT OF THE INVENTION The front panel module support and the front panel module comprising said carrier according to the present invention are intended to remedy the disadvantages mentioned above. Thus, a first object of the invention relates to a support structure for a front-end module of a motor vehicle, said support structure comprising a lower crossmember, a first side post, a second side post, and an upper rail. to define a frame, said upper cross member being formed of a hybrid material comprising a plastic material and a metallic material. In other words, the amounts are arranged to connect the rails together.
    [0007] Advantageously, the upper cross member comprises an insert made of a metal material and coated with a plastic material. Advantageously, the support structure comprises a support wing attached to one end of the upper rail. Advantageously, the support wing is made of a metal material. Advantageously, the support structure comprises a support piece for connecting said support wing to the support structure.
    [0008] Advantageously, the support member comprises an insert made of a hybrid material comprising a plastic material and a metallic material. A second object of the invention is a front-end module comprising a support structure according to the above features. BRIEF DESCRIPTION OF THE DRAWINGS The objects, objects and features of the present invention and its advantages will become more clearly apparent from the following description of the preferred embodiments of the invention with reference to the drawings in which: FIG. 1 shows an exploded perspective view of a support structure for a front-end module according to a first embodiment of the invention; FIG. 2 shows an assembled and perspective view of the FIG. 3 shows a front view of the support structure according to FIG. 1, FIG. 4 shows a front view of a support wing attached to a support structure according to FIG. part of the support structure of the front face module according to an embodiment of the present invention.
    [0009] DETAILED DESCRIPTION OF THE EMBODIMENTS The following detailed description is intended to explain the invention in a sufficiently clear and complete manner, particularly by way of examples, but should not be construed as limiting the scope of the invention. protection to the particular embodiments and examples presented below. Figure 1 shows a support structure 10 for a front-end module 15 (not shown) of a motor vehicle. The support structure 10 includes a lower cross member 12, a first side post 14, a second side post 16 and an upper cross member 18 assembled by means of connections, such as screws, to form a closed structure. The lower cross member 12, the first side post 14 and the second side post 16 are made entirely of a plastic material, such as 40% long glass fiber reinforced polypropylene. Thus, the support structure 10 is relatively lighter than a support structure according to the prior art. The upper cross member 18 comprises an insert (not shown) of tubular shape, for example, made of a metallic material, such as steel, and covered, after a molding process, with a plastic material. such as polypropylene reinforced with glass fibers 40% long. The upper cross member 18 thus comprises a hybrid material formed of a metallic material and a plastic material. The dimensions of the insert are determined so that the level of rigidity and strength of the support structure 10 complies with the standards imposed by the automotive safety regulations in a frontal collision between a motor vehicle and a vehicle. pedestrian. The insert can constitute either all or part of the upper cross member 18. The insert thus integrated within the upper cross member 18 also performs a reinforcing plate function 3037553 5 to prevent accidental opening of the vehicle hood automobile during a frontal collision of the motor vehicle with a pedestrian. The support structure 10 also includes a first support wing 20 and a second support wing 22 shown in FIG. 1. The first and second support wings 20, 22 are adapted to be connected to each end of the upper rail. 18 by means of connections such as screws. The first and second support flanges 20, 22 may be formed by a stamping process in a material such as aluminum or steel.
    [0010] FIG. 2 shows the support structure 10 according to the first embodiment of the invention, with the first and second support wings 20, 22 assembled on the upper crossmember 18.
    [0011] FIG. 3 shows a front view of the support structure 10 assembled with the first and second support wings 20, 22. FIG. 4 shows in detail the connection of the first support wing 20, shown in FIGS. , 2 and 3, on a portion of the support structure 10 (partially shown). As shown in FIG. 4, the first support flange 20 may comprise a support piece 24 for connecting said first support flange 20 to the support structure 10 by means of a connecting element 25. support 24 can be made by means of an insert made of a metallic material and covered, at the end of an overmolding process, with a plastic material. The second support flange 22 is connected to the support structure 10, similarly to the first support flange 20, by means of a support piece (not shown) and a connecting element (not shown).
    [0012] Thus, the support structure 10 may comprise, on the one hand, a metal insert located within the upper cross member 18 and, on the other hand, a metal insert located in the support piece 24 for the connection of the first 3037553 6 support wing 20 and a metal insert located in the support part of the second support wing 22. Thus the presence of all the metal inserts ensures a level of rigidity and strength of the support structure 10 of firstly, at the level of the upper cross member 18 and, secondly, at the level of the attachment of the first and second support wings 20, 22. The support structure 10 thus constituted represents a reduced weight of the order 30 to 40% relative to the weight of a support structure according to the prior art. Thus, the support structure 10 according to the present invention makes it possible to reduce the fuel consumption of the motor vehicle, and consequently to reduce carbon dioxide (002) emissions. The support structure 10 according to the present invention thus makes it possible to combine a relative rigidity with respect to the protection of a pedestrian in the event of a frontal impact with relative flexibility to absorb any vibrations experienced by the devices within the module of the front face when the motor vehicle is moving. In addition, a support structure according to the invention requires a limited number of steps in its manufacture compared with the number of steps required to manufacture a fully metal support structure according to the state of the art.
