    专利说明:

    [0001] The present invention relates to a motor vehicle tailgate comprising a plastic box comprising at least one structural element for supporting a rear window.
    [0002] It is known to produce structural elements hatch sheet metal, for example side uprights surrounding the rear window, or a lower horizontal crossbar arranged in the lower part of the rear window. Such a structural element in sheet metal is generally in the form of an elongated hollow body with a closed cross section, in order to ensure the rigidity of the tailgate and to allow the arrangement of a gluing track of the rear window which is reported on the structural element. It is also possible to produce structural elements of plastic material, not requiring a closed section and having for example a greater depth and equivalent stiffness. In this case, the section of the structural element may be U-shaped with an opening facing the outside of the vehicle and subsequently closed by the tailgate bezel. In these two types of structural elements, the space delimited by the structural element and possibly the bezel is an inaccessible closed space. The present invention aims to provide a tailgate arranged more optimally and thus limit the manufacturing costs of the rear of the vehicle. To this end, the subject of the invention is a motor vehicle tailgate comprising a plastic box comprising at least one structural element for supporting a rear window, the structural element being elongated in a so-called longitudinal direction, in which the structural element delimits, with the rear window, a housing having an inner opening, the inner opening being closed by means of a liner attached to form at least partially a longitudinal wall of the housing, adjacent to the rear window and arranged towards the inside of the rear window, so that the housing receives an electrical element of the vehicle.
    [0003] Thus, it is proposed to use a part of the vehicle traditionally not accessible after assembly, and therefore not used, to associate new functions of the vehicle, namely the housing of electrical functions. Indeed, the inventors have discovered that, when using plastic structural elements, the longitudinal inner wall of the structural element disposed towards the inside of the rear window, or second leg of the U. is not not entirely necessary to ensure the rigidity function of the amount and can be replaced by a pad. Such a lining no longer needs to fulfill a function of rigidity and can advantageously fulfill a function of closing a dry zone, for accommodating an electric element. There is thus an easy solution for integrating electrical elements in the recessed form of the tailgate structural element, which is added to a decorative function provided by the lining, in particular allowing the interior of the trunk to be concealed. structural element. Furthermore, and particularly advantageously, a hatchback is provided that can easily integrate rear optical elements, including stop lights, reversing, turn signals, while the rear optics are traditionally provided directly on the vehicle, for example in the lower part, on the body in the side areas or in air deflectors, also called spoilers, placed in the extension of the roof or side parts of the rear. Thus by providing the taillights on the tailgate rather than on the rest of the vehicle, on the one hand we can propose new aesthetic configurations for the tailgate and the rest of the vehicle, on the other hand the rear of the vehicle is less constrained by the presence of optical elements, for example it is not necessary to provide sealed baffles.
    [0004] By "plastic box" is meant a box including, but not limited to, plastic. It is understood that this expression includes in particular a box comprising a composite material. The term "electrical element of the vehicle" any member delivering, receiving, or passing electrical energy, for example and not exclusively an optical element, a camera, a sensor, a receiver, a transmitter, an antenna or a electric wire. Thus the electric element can have a wide variety of functions, such as the temperature function, the rain function, the anti-pinch function, the radar function, the traffic light function, or the style lighting function, and also use a wide variety of technologies, such as infra-red, radio waves, capacitive sensor, etc. It is understood that "the inner opening" is an opening made in a longitudinal wall of the housing adjacent to the rear window and disposed towards the inside of the rear window, that is to say which is closer to the center of the rear window. the rear window that an opposite longitudinal wall, which is considered to be an outer longitudinal wall of the housing. In other words, the inner side is oriented towards the center of the rear window and the outer side is oriented in the opposite direction. A longitudinal wall is understood by reference to the elongated shape of the structural member, the direction of elongation defining the longitudinal direction. It is understood that the inner longitudinal wall is a wall which is adjacent to the rear window, often substantially perpendicular to the rear window, and which is therefore different from a longitudinal bottom wall which is substantially parallel to the rear window. It will further be understood that a tailgate "rear window" is a rear window of the vehicle, for example made of glass. It is generally transparent and can locally present opaque portions, for example by screen printing areas. According to advantageous but not compulsory aspects of the invention, the tailgate may incorporate one or more of the following features, taken alone or in combination. - The structural element belongs to the group comprising a lateral amount and a horizontal cross. In particular, the plastic casing may comprise three structural elements, namely two lateral uprights connected by a lower horizontal crossbar. - The lining forms a support of the electric element. Thus, the electrical element could be pre-assembled to the liner before this subassembly is attached to the structural member. The fact that it is the lining, and not the structural element, that carries the electrical element also facilitates the maintenance and replacement of the electrical element. In addition, the integration of the electrical element in the lining makes it possible to better manage the optional functions of a given vehicle series on the basis of a single tailgate. Indeed, as the gasket is an insert, it can be expected to report different fittings according to the electrical options that we want to integrate. However, it is easier to manage the complexity by producing different shapes on the fittings, generally smaller in size, than on larger form liners. The electric element is an optical element, for example a light source. - The lining has a fixing portion of a light source and a fixing portion of a reflector, these fixing portions being for example orifices made in offset bearing faces, that is to say being at distances from the rear window which are different from each other. The light source is for example in the form of an assembly of a printed circuit board type PCB ("printed circuit board 3037873 -4-" in English) and light emitting diodes (LEDs). The reflector may comprise one or more clips to cooperate with the orifice or holes so as to be fixed on the liner. Moreover, it is also possible to provide a part for fixing an electric cable in the lining. Thus, the liner may carry a plurality of optical elements. The electric element comprises an element of the group consisting of a camera, a sensor, a receiver, an antenna. These elements are often used for optional functions in a vehicle series. It is therefore interesting to integrate them into the trim. - The electrical element is a receiver or current transmitter, which differs from a wire or electric cable passing only current. Thus, while an electrical wire could relatively easily be housed in a non-dry area, by sealing the wire, a current receiver or transmitter, such as an optical element, a camera, a sensor, a receiver or still an antenna, require to be housed in a dry zone and the solution proposed here provides a particularly interesting advantage. 20 - The structural element, assembled with the bezel and the lining, has a cross section whose outer contour has substantially a quadrilateral shape, for example a trapezoidal shape, one side of the quadrilateral being formed by the rear window, two other sides The backs are formed by the structural post and the last side, connecting the rear window and the structural element, being at least partially formed by the liner. Alternatively, one side of the quadrilateral is formed by the rear window, an adjacent side is formed by the structural upright, an opposite side, adjacent to the rear window, is formed by the trim, and the last side being formed in part by the upholstery and partly by the structural amount. 30 - The lining is mounted on the structural upright removably, for example by means of a rivet, screw, staple of a clip or any other technical solutions that allow easy disassembly of the part garnish. Thus, the lining can easily be dismantled from the structural element to facilitate maintenance and replacement of the electrical element. The lining comprises a longitudinal edge of connection with the rear window, provided with a flexible seal, for example a blade-type seal or any other solution which makes it possible to achieve a closure or a light-tightness. in the case where the electric element has a lighting function. Preferably, the rear window comprises a screen printing area at the location of this seal to conceal the connection with the liner. 5 - The lining is made of thermoplastic material. The structural amount is made of thermoplastic material, thermosetting material or composite material. The invention will be better understood on reading the appended figures, which are provided by way of example and are not limiting in nature, in which: FIG. 1 is a schematic perspective view of the exterior of a hatchback; motor vehicle according to one embodiment; - Figure 2 is a schematic cross sectional view along the plane 1-1 of an amount of the tailgate of Figure 1; Figure 3 is a fragmentary and schematic perspective view of the lining of the post of Figure 2; - Figure 4 is a schematic cross sectional view of the lining of the pillar of Figure 2; - Figure 5 is a schematic sectional view of the reflector of the amount of the figure - Figure 6 is a schematic cross sectional view along the plane 11-11 of a cross member of the tailgate of Figure 1; FIG. 7 is a detailed view of part III of FIG. 6.
    [0005] Referring now to FIG. 1. A motor vehicle tailgate 10 comprises a plastic box comprising, in this example, two lateral uprights 16 and a lower horizontal cross member 17 connecting the lateral uprights 16. The uprights 16 and the traverse 17 surround and support a glass rear window 12. Each upright 16 and the crossmember 17 each constitute an elongated structural member, each extending in a longitudinal direction corresponding to the axis of elongation of the structural member. Specifically, the cross member 17 is elongated in a substantially horizontal direction by considering the tailgate when mounted on the vehicle, so that the longitudinal direction of the cross member 17 corresponds to this substantially horizontal direction. The side uprights 16 are extended in a substantially vertical direction when the tailgate is mounted on the vehicle, so that the longitudinal direction of the side uprights 16 is the substantially vertical direction. As can be seen in FIG. 2, the upright 16 has a "semi-U" cross-section, that is to say that a lateral branch of the inner U. is not complete. . The outer wall of the upright 16 is glued to the bezel 12 by a bead of glue 18, which ensures both the maintenance of the bezel 12 and the sealing of the box vis-à-vis the outside of the vehicle. The telescope 12 has a serigraphy zone 20 at the right of the adhesive tape 18. It is understood here that the outside of the vehicle corresponds to the part further from the center of the rear window 12, namely the left part of the 2 and that the interior of the vehicle corresponds to the part being closer to the center of the rear window 12, namely the right part of FIG. 2. The upright 16 delimits, with the rear window 12, a housing 14. having an inner opening which is closed by means of an insert 22, so as to at least partially form a longitudinal wall of the housing, adjacent and disposed towards the inside of the rear window 12. The lining 22 is mounted to the upright 16 in a removable manner, for example by means of a rivet 24. Moreover, the liner 22 comprises a longitudinal edge of connection with the bezel 12 provided with a flexible seal 26 of the blade type. The bezel 12 comprises a second screen printing zone 40 at the right of the seal 26. Thus, the upright 16, assembled with the bezel 12 and the lining 22, has a cross section whose external contour has substantially a quadrilateral shape, here a trapezoidal shape. A first side of the quadrilateral is formed by the rear window 12 and two other consecutive sides, the two left and lower sides, are formed by the upright 16. The last side, the right side connecting the rear window 12 and the upright 16 is at least partially formed by the liner 22. In this example, substantially all the last side, except the corner portion, is formed by the liner. The upright 16 also comprises a wedge rib 36 for positioning elements described below. In this example, the liner 22 forms a support for several electrical elements received in the housing 14. In particular, it carries the assembly of a printed circuit PCB 32 provided with LEDs 33 and a connector cable 34. The liner 22 also forms 35 A support for a reflector 30. As can be seen in Figure 3, the liner 22 has a first group of support faces 42 and a second group of support faces 44, which are offset by one with respect to the other, that is to say that the bearing faces 42 and the bearing faces 44 are at distances relative to the rear window 12 different from each other. Fixing means 46, 48 are made respectively in these bearing faces 42, 44 for fixing the reflector 30 and the PCB 32. As illustrated in FIG. 5, the reflector 30 has at least one clip 56 intended to be inserted in the orifice 46 in order to fix the reflector 30 to the lining 22. Similarly, clips 48 made on the bearing faces 44 are able to clasp the PCB circuit 32. The lining 22 is also visible In FIG. 4, in addition to the means for fixing the optical elements, the lining comprises means 50 for fixing the connector cable 34 in the form of a recess with elastic tabs 58 for gripping the cable 34. 22 comprises in its wall covering the lateral opening a hole 54 which allows its fixing by the rivet 24 on the upright 16. Referring now to Figures 6 and 7 illustrating a second example of structural element.
    [0006] In this case, the telescope 12 extends vertically and covers in its lower part the junction of an outer skin 15 of the tailgate 10 with an inner lining of the tailgate, composed by the box. It is therefore understood that here the outer part of the telescope 12 is at the bottom and that the inner part of the telescope, being closer to the center of the telescope, in the upper part of the figure. The outer skin 15 is fixed to the box of the tailgate 10 at the cross member 17 by a bonding tape 78. The bezel 12 has a screen printing area 70 to the right of the bonding tape 78. The cross member 17 is part of the box of the tailgate and constitutes a structural element.
    [0007] The cross-member 17 delimits, with the rear window 12, a housing 74 having an interior opening which is closed by means of a trim 72 attached to form a longitudinal wall of the adjacent housing and disposed towards the inside of the rear window. 12. Here the crosspiece 17 has locally a section "senni-U" 35 in which the bottom of the U is not complete and the inner side branch of the U does not exist. In addition, the lining 72 comprises a longitudinal edge of connection with the rear window 12 provided with a flexible seal 76 of the blade type. The telescope 12 comprises a second screen printing area 90 at the right of the seal 76.
    [0008] In this example, the liner 72 forms a support for an electrical element 80, for example an outdoor camera or lighting. For this purpose, the lining 72 comprises a substantially horizontal plate 76 which supports the electrical element 80. The lining 72 is mounted on the cross-member 17 removably, by means of a screw. In the examples described, the tailgate box 10 is made of composite material, such as fiber-reinforced plastics material.
    [0009] The invention is not limited to the examples presented and other embodiments will become apparent to those skilled in the art. In particular, the structural element may take a different general form. Preferably, it has a "semi-U" cross-section, i.e., at least one side branch of the U is absent.
