    Motor vehicle opening
    The present invention relates to a motor vehicle opening comprising a reinforcing element extending at least partly along a main plane, intended to reinforce fixings and the environment of a lock of the opening, and a plastic casing , comprising an internal part molded at least partially on an internal face of the reinforcing element.
    The invention relates, for example, to motor vehicle openings, such as tailgates or doors.
    There is known in the prior art, a motor vehicle opening having a structural plastic part forming a body of the opening.
    In order to meet the constraints defined by the vehicle manufacturers, in terms in particular of deformation of the opening according to criteria of bending, torsion, lateral support, exceptional effort (as defined by regulation number 11 of the Economic Commission for the Europe of the United Nations (UN / ECE), in its version of 15 June 2015, concerning the uniform requirements relating to the approval of vehicles with regard to door locks and fasteners), etc., the structural rigidity of this part needs to be reinforced. The commonly adopted solution consists in adding a reinforcing element, for example in metal, to the plastic structural part, in order to stiffen the assembly.
    In known manner, the reinforcing element is attached and screwed onto the plastic structural part to form a reinforced structural part.
    The fixing of the reinforcing element on the plastic structural part requires several operations such as operations of installation of screw inserts on the plastic part, the positioning of the reinforcement on the plastic part, the installation of pre-holding screw, and finally a screwing operation of the reinforcing element on the structural plastic part.
    The multiplicity of the abovementioned operations for fixing the reinforcing element on the structural part requires a relatively long time and entails a high cost of the reinforced structural part.
    In addition, the reinforcement element being generally fixed on the plastic structural part by screws, the stresses applied on the reinforced structural part are often concentrated on the fixing points at the level of the screws and can exceed the admissible thresholds by the material. structural part plastic.
    This results in poor resistance over time of the reinforced structural part as well as a degradation of the mechanical connection between the plastic structural part and the reinforcing element.
    An objective of the invention is to provide a vehicle opening in which a good mechanical connection is ensured between the envelope and the reinforcement part. An objective of the invention is also to propose an inexpensive vehicle opening element.
    To this end, the invention relates to a vehicle opening of the aforementioned type in which the reinforcing element comprises at least one orifice, and the envelope comprises at least one external part comprising a segment passing through said orifice and a covering covering part. locally an edge of the orifice on an external face of the reinforcing element.
    By making a segment of the envelope penetrate into an orifice of the reinforcing element and by providing a covering part on the external face of the reinforcing element, a good mechanical connection obtained in a single molding operation is ensured between the envelope and the reinforcement piece.
    In particular, the segment and the overlap area ensure good adhesion of the envelope to the reinforcement piece.
    The segment penetrating the orifice of the reinforcing element and the overlap zone also limit the displacements which may appear between the reinforcing element and the casing following the mechanical stresses applied to the opening of the vehicle.
    According to preferred embodiments of the invention, the vehicle sash also has one or more of the following characteristics, taken in isolation or in any technically possible combination (s):
    the reinforcing element comprises a plurality of orifices, the external part of the envelope comprising a plurality of segments each passing through an orifice of the plurality of orifices of the reinforcing element and a plurality of covering parts each covering locally the edge of an orifice of the plurality of orifices on the external face of the reinforcing element, the external part of the envelope comprising at least one rib connecting the covering parts to one another;
    the internal part of the envelope comprises a central portion at least partially covering the internal face of the reinforcing element, extending along a plane parallel to the main plane, the envelope further comprising at least one upper portion and a lower portion each extending from the central portion, the upper portion and the lower portion being inclined at a non-zero angle relative to the central portion and extending projecting from the central portion on the side of the face external of the reinforcing element;
    the outer part of the casing comprises at least one reinforcing rib projecting from the external face of the reinforcing element, said reinforcing rib extending between the upper portion and the lower portion of the casing;
    - The reinforcing element comprises a central part extending at least partly along the main plane P and parts of curved lateral ends forming a non-zero angle with the central part, the envelope comprising at least two ribs of end extending between the upper portion and the lower portion of the casing, each curved side end portion of the reinforcing element being at least partially overmolded by an end rib;
    - An upper end of the reinforcement element is inclined relative to the central part of the reinforcement element, the upper end of the reinforcement element being overmolded by the envelope;
    - An opening is made in a thickness of the reinforcing element to receive a lock mechanism of the opening, an edge of the opening extending between the external face and the internal face of the reinforcing element and being overmolded by the envelope;
    the reinforcing element has at least one barrel projecting from the internal face of the reinforcing element, the barrel comprising a first wall defining a hole and a second wall overmolded by the envelope, the second wall being opposite the first wall;
    - the envelope is made in one piece;
    - Said opening forms at least part of a tailgate comprising a lock fixed at least partly on the reinforcing element.

    - Figure 4 is a sectional view of Figure 2, defined along the section plane represented by the axis IV-IV in Figure 2, and

    A motor vehicle 10 comprising an opening 12 is shown in FIG. 1.
    A longitudinal direction is represented in the present description, represented by the axis X, corresponding to the front-rear direction of the vehicle 10, named in the following description "longitudinal direction X".
    In this description, a transverse direction is defined, perpendicular to the longitudinal direction, parallel to the spacing of the front wheels (not shown in the drawings) or the rear wheels 14 of the motor vehicle 10, named in the following description. "Transverse direction Y >>.
    Furthermore, in the present description, a direction of elevation represented by the axis Z is defined, named in the following description "direction of elevation Z". The elevation direction Z is a direction perpendicular to the longitudinal direction X and to the transverse direction Y.
    In the embodiment described here, the opening 12 is a tailgate of the motor vehicle 10.
    The opening 12 is articulated on a body element of the vehicle 10, in the vicinity of the upper edge of an access opening to the interior volume of the rear boot. The interior volume of the rear trunk is delimited at the bottom by a body element 18 of the vehicle 10.
    The opening 12 is suitable for pivoting about an axis parallel to the transverse direction Y between an open position (not shown here), in which access to the boot is possible and a closed position, in which the access to the trunk from outside the vehicle 10 is impossible.
    Such an opening 12 comprises a structural part 20, forming a body of the opening 12, in which is intended to be arranged a lock making it possible to lock the opening 12 in the closed position.
    In the present example, the structural part 20 is not visible from outside the vehicle 10 and forms at least part of the internal face of the opening.
    With reference to FIGS. 2 and 3, the structural part 20 comprises a reinforcing element 24 and a casing 26 of plastic material overmolded on the reinforcing element 24.
    The reinforcing element 24 comprises a body 28. The body 28 has an external face 30 and an internal face 32. The external face 30 and the internal face 32 are substantially parallel with respect to each other.
    In the present description, the term “internal face” means a face oriented towards the inside of the vehicle 10 and the term “external face” means a face oriented towards the outside of the vehicle 10. In addition, the present description by "internal part", a part of an element oriented towards the inside of the vehicle 10 and by "external part", a part of an element oriented towards the outside of the vehicle 10.
    In this description, the term “thickness of the reinforcement element 24” is also understood to mean a distance measured between the external face 30 and the internal face 32 of the body 28 of the reinforcement element 24.
    Referring to Figure 3, the body 28 has a central portion 34 extending along a main plane P, for example normal to the longitudinal direction X.
    In the central part 34 of the body 28 of the reinforcement element 24, the external face 30 and the internal face 32 of the reinforcement element 24 are substantially parallel to each other in a plane normal to the longitudinal direction X.
    The body 28 also has an upper end part 36 curved with respect to the central part 34 of said body 28, towards the outside of the vehicle 10. In the present description, the term "upper" means a element which is located above another element with respect to the direction of elevation Z of the vehicle 10.
    The upper end part 36 of the reinforcing element 24 extends in a plane forming an angle a with the main plane P, in which extends the central part 34 of the body 28. In other words, the part of upper end 36 forms a non-zero angle with the central part 34 of the body 28 of the reinforcing element 24. For example, the upper end part 36 forms an angle a between 90 degrees and 180 degrees with the central part 34 , for example 90 degrees.
    With reference to FIG. 4, the body 28 also has two lateral end parts 39, 40 curved with respect to the central part 34. The lateral end parts 39, 40 are parts of the body 28 located on either side other of the central part 34 of the body 28 in the transverse direction Y.
    Each lateral end part 39, 40 extends in a plane forming a non-zero angle β with the main plane P in which extends the central part 34 of the reinforcing element 24. In other words, each part of lateral end 39, 40 forms a non-zero angle β with the central part 34 of the body 28 of the reinforcing element 24. For example, each lateral end part 39, 40 forms an internal angle β of between 90 degrees and 180 degrees with the central part 34. In this case, the lateral end parts 39, 40 form an angle β substantially equal to 90 degrees with the central part 34.
    The body 28 also has at least one orifice 42, visible in FIG. 3. The orifice 42 is formed in the central part 34 of the body 28.
    The orifice 42 opens out, that is to say that it crosses the external face 30 and the internal face 32 of the body 28.
    According to one embodiment, the body 28 has a plurality of orifices 42 regularly distributed in the transverse direction Y. For example, the body 28 has between one and ten orifices 42.
    The body 28 also has at least one opening 44 formed in the thickness of the reinforcing element 24, intended to receive at least one mechanism for the lock of the opening 12 of the vehicle 10. More specifically, the opening 44 is formed in a thickness of the central part 34 of the reinforcement element 24. The opening 44 constitutes a through hole, passing through the external face 30 and the internal face 32 of the body 28 of the reinforcement element 24.
    The opening 44 has, for example, a substantially rectangular section in a normal plane with longitudinal direction X.
    The opening 44 defines a border 45 of the body 28 of the reinforcing element 24. The border 45 corresponds to the part of the body 28 forming the periphery of the opening 44. The border 45 extends between the external face 30 of the body 28 and the internal face 32 of said body 28. Thus, the edge 45 constitutes a thickness of the body 28 of the reinforcing element.
    With reference to FIG. 5, the reinforcing element 24 further comprises at least one barrel 46 projecting inwardly from the internal face 32 of the body 28 of the reinforcing element 24.
    The barrel 46 has a first wall 48 defining a hole 50 in the body 28 of the reinforcing element 24 and a second wall 52 projecting from the internal face 32 of the body 28. The second wall 52 is opposite to the first wall 48 of the barrel 46, that is to say that the second wall 52 of the barrel 46 forms the external diameter of the hole 50 and that the first wall 48 of the barrel 46 forms the internal diameter of the hole 50. In other words, the first wall 48 of the barrel 46 is oriented towards the inside of the hole 50 and the second wall 52 is oriented towards the outside of the hole 50.
    The first wall 48 of the barrel 46 is obtained by deformation of the external face 30 of the body 28 of the reinforcing element 24 and the second wall 52 of the barrel 46 is obtained by deformation of the internal face 32 of the body 28 of the element reinforcement 24.
    As can be seen in FIG. 2, the barrel 46 is arranged, for example, in line with the opening 44 in the transverse direction Y. In the embodiment described here, the barrel 46 is adapted to receive a fixing element for the lock, such as a screw.
    The body 28 has, for example, a second barrel 54, identical to the first barrel 46, arranged on the other side of the opening 44 in the transverse direction Y, in line with said opening 44.
    As a variant, the body 28 has more than two barrels for fixing the lock.
    Still alternatively, the barrel (s) can be arranged differently with respect to the opening 44, and be arranged, for example, above the opening 44 and / or below the opening 44.
    The barrels 46, 54 ensure, because of their geometry, an anti-creep function of the plastic of the casing 26 when the fastening elements of the lock are tightened.
    The reinforcing element 24 can be made, for example, of metal such as steel, aluminum, magnesium, or the like.
    When the reinforcing element 24 is made of metal, the reinforcing element 24 has, for example, a thickness of between 0.5 millimeters (mm) and 5 mm.
    Alternatively, the reinforcing member 24 is made of a composite material. For example, the composite material is a material made of glass fibers, carbon fibers or other fibers, such as natural fibers, embedded in a matrix of thermoplastic or thermosetting material.
    When the reinforcing element 24 is made of a composite material, the thickness of the reinforcing element 24 is, for example, greater than 0.5 mm, and in particular between 0.5 mm and 10 mm.
    Envelope 26 is now described.
    As can be seen in FIG. 2, the casing 26 is at least partially overmolded on the reinforcing element 24. For example, the casing 26 is made of a plastic material.
    In the embodiment described here, the casing 26 is formed in one piece.
    With reference to FIG. 3, the casing 26 has a central portion 58 covering the internal face 32 of the central part 34 of the reinforcing element 24. Thus, the central part 34 of the reinforcing element is overmolded by the central portion 58 of the casing 26. The central portion 58 of the casing 26 extends along a plane parallel to the main plane P in which the central portion 34 of the body 28 of the reinforcing element 24 extends.
    The central portion 58 of the casing 26 forms an internal part of the casing 26. In other words, the central portion 58 is oriented towards the interior of the vehicle 10 relative to the reinforcing element 24.
    The casing 26 also has an upper portion 60, visible in FIG. 2 and a lower portion 62 extending from the central portion 58 of the casing 26, visible in FIGS. 2 and 3. The upper portion 60 and the lower portion 62 are inclined at a non-zero angle relative to the central portion 58 of the casing 26.
    As visible in FIG. 3, the lower portion 62 molds a lower free edge 63 of the reinforcement piece 24.
    The casing 26 has an external part comprising at least one segment 64 passing through an orifice 42 and a covering part 66 locally covering the edge of said orifice 42 on the external face 30 of the body 28 of the reinforcing element 24. The covering part may have a circular or oblong section, in a section plane normal to the transverse direction X.
    By “external part of the casing 26” is meant a part of the casing 26 oriented towards the outside of the vehicle 10 relative to the reinforcing element 24, that is to say extending from the side of the external face 30 of the reinforcing element 24.
    By "locally" is meant that the covering part 66 extends over a limited area around the edge of the orifice 42 of the reinforcing element 24, for example over an area extending over a distance between 0 , 5 mm and 30 mm around the orifice 42, measured from the center of the orifice 42. It is understood that the overlap zone 66 does not cover the entire external face 30 of the body 28 of the reinforcing element 24 According to one embodiment, when several orifices 42 are formed in the body 28 of the reinforcing element 24, the external part of the casing 26 comprises a plurality of segments 64 passing through each of the orifices 42, and a plurality of parts covering 66 locally covering the edge of each of the orifices 42 on the external face 30 of the reinforcing element 24.
    Thanks to the segment 64 penetrating into the orifices 42 and to the covering part 66 locally covering the edge of an orifice 42, precise positioning is ensured between the reinforcing part 24 and the casing 26 and a good mechanical connection is created between the reinforcement piece 24 and the casing 26.
    In this case, as visible in FIG. 2, a covering part 66 is spaced from another covering part 66 by a part of the external face 30 of the body 28 of the reinforcing element 24, that is to say saying that there is an absence of material forming the envelope 26 between each of the overlap zones 66.
    The outer part of the casing 26 further comprises a transverse rib 68 connecting the covering parts 66 to one another. The transverse rib 68 projects from the external face 30 of the reinforcing element 26 and extends in the transverse direction Y.
    The outer part of the casing 26 also has a plurality of reinforcing ribs 70.
    Reinforcement ribs 70 project from the external face 30 of the body 28 of the reinforcement element 24, and extend between an external face 60A of the upper portion 60 of the casing and an external face 62A of the lower portion 62 of the casing 26 in the direction of elevation Z.
    Other reinforcement ribs 70 project from the external face 30 of the body 28 of the reinforcement element 24, between a functional element 71 overmolded from the casing 26, integral with the external face 60A of the upper portion 60 of the casing 26, and the external face 62A of the lower portion 62 of the casing 26.
    The reinforcing ribs 70 have, in this example, different heights. The term "height" in the present description means a distance of an element measured in the longitudinal direction X. The reinforcing ribs 70 have heights ranging, for example, between 1 mm and 60 mm.
    The external part of the envelope 26 further comprises, in this example, two end ribs 72, 74 extending between the external face 60A of the upper portion 60 of the envelope 26 and the external face 62A of the portion lower 62 of the casing 26, in the direction of elevation Z. The end ribs 72, 74 also extend projecting from the external face 30 of the central part 34 of the body 28 of the reinforcing element 24.
    The lateral end portions 39, 40 of the reinforcing element 24 are at least partially overmolded respectively by an end rib 72, 74, as shown in more detail in FIG. 4. In particular, each rib d end 72, 74 covers the external face 30 of the lateral end parts 39, 40 of the body 28 and a free edge 39A, 40A of each of the lateral end parts 39, 40.
    As a variant, each end rib 72, 74 covers the internal face 32 of the lateral end parts 39, 40 of the body 28 and a free edge 39A, 40A of each of the lateral end parts 39, 40.
    Again, as a variant, each end rib 72, 74 covers both the internal face 32 and the external face 30 of the lateral end parts 39, 40 of the body 28 and a free edge 39A, 40A of each of the parts d lateral ends 39, 40. In this case, each end rib 72, 74 completely molds the lateral end parts 39, 40 of the body 28.
    Each of the end ribs 72, 74 has a length substantially equal to the length of the lateral end portion 39, 40 which it molds.
    The transverse rib 68 is integral with the end ribs 72, 74 and the reinforcing ribs 70.
    The transverse rib 68, the reinforcement ribs 70 and the end ribs 72, 74 make it possible to limit the deformations of the reinforcement element 24 and to maintain the reinforcement element 24 in the main plane P by preventing any movement of said reinforcement element 24 outside the main plane P. This then makes it possible to keep the reinforcement element 24 "taut".
    The fact of overmolding the lateral end parts 39, 40 of the reinforcing element 24 makes it possible to improve the tear resistance of the casing 26. In addition, the central part 34 of the reinforcing element 24 remains substantially plane when the structural part 20 of the opening 12 is subjected to forces. In other words, the deformations of the reinforcing element 24 are limited.
    In addition, as visible in FIG. 3, the upper end portion 36 of the reinforcing element 24 is overmolded by the casing 26. More precisely, the external part of the casing 26 has a rib 78 projecting from the central portion 58 of the casing 26, in which is included the upper end portion 36 of the body 28 of the reinforcing element 24.
    The rib 78 connects upper ends of the reinforcement ribs 70 to each other.
    In addition, as visible in FIGS. 2 and 3, the edge 45 of the opening 44 is covered by the casing 26 and is flush with the external face 30 of the body 28 of the reinforcing element 24, that is to say say that the envelope 26 covers the thickness of the reinforcing element 24 at the edge 45 of the opening 44.
    Thanks to these arrangements, the reinforcing element 24 is concealed by the casing 26 in the opening 44 of the reinforcing element 24.
    Furthermore, the fact that the edge 45 is covered by the casing 26 contributes to obtaining a good mechanical connection between the reinforcing element 24 and the casing 26.
    In addition, as visible in FIG. 5, the second wall 52 of the barrel 46 is overmolded by the casing 26. In other words, the internal part of the casing 26 formed by the central portion 58 of the casing 26 is flush with one end free 46a of the barrel 46.
    The second wall of the other barrel 54 is also overmolded by the casing 26, that is to say that the internal part of the casing 24 formed by the central portion 58 of the casing 26 is flush with a free end of the was 54.
    Thanks to this arrangement, the elements for fixing the lock are introduced into the hole 50 formed by the barrel 46, without creep of a plastic part of the casing 26.
    When the reinforcing element 24 has one or more other barrel (s) 54, the fixing elements of the lock are also introduced into each of the holes formed by the said barrel (s), without creep of a plastic part of the envelope.
    A method of manufacturing the structural part 20 will now be described.
    The reinforcing element 24 is first supplied. It is inserted into a mold, the mold comprising a die and a punch forming a molding cavity having a shape complementary to that of the casing 26.
    The reinforcing element 24 is placed in the mold either against the punch or against the die.
    The die and the punch form a chamber in which the reinforcing element 24 is placed.
    Then, the plastic is injected into the chamber and the plastic fills the chamber, from the punch to the die.
    As a variant, the envelope can be formed by compression around the reinforcing element 24.
    Thanks to the invention described above, a structural part 20 of the opening 12 of the reinforced vehicle 10 is obtained, in which a good mechanical connection is ensured between the casing 26 and the reinforcing part 24.
    The good mechanical connection between the reinforcing element 24 and the plastic casing 26 is ensured by virtue of the overmolded surface of the casing 26 corresponding to the internal part of the casing 26, thanks to the segments 64 of the casing 26 passing through the orifices 42, as well as thanks to the overlapping zones 66 locally covering the edges of the orifices 42 on the external face 30 of the body 28 of the reinforcing element 24.
    The good mechanical connection between the reinforcing element 24 is also ensured by virtue of the ribs 70 of the casing 26, the overmolding of the end ribs 39, 40 and of the rib 78 of the casing 26 on corresponding parts of the reinforcement element 24.
    All of these parts of overmolding of the casing 26 on corresponding parts of the reinforcing element 24 allows a distribution of the forces over the entire reinforcing element 24, contrary to the state of the art where the reinforcement element is attached then screwed by screws and where the stresses are concentrated only on these fixing points
    Furthermore, thanks to the invention, the structural part 20 can be obtained in a single fixing step, that is to say in a single overmolding step of the casing 26 on the reinforcing element 24.
    Thanks to the invention, the molding operations necessary for obtaining a good mechanical connection between the reinforcing part 24 and the casing 26 are limited. The invention also makes it possible to obtain a structural part 20 forming a body opening 12 resistant to mechanical stresses.
    Furthermore, the invention makes it possible to obtain a structural part 20 of opening 12 of vehicle 10 simple and inexpensive to manufacture.
