Description

Title of the invention: Arrangement comprising a body element receiving a stop for a vehicle opening. Technical field of the invention

[0001] The invention relates to an arrangement comprising a body element receiving a stop that comes into contact with a vehicle opening in the closed position of such opening. The invention further relates to a vehicle comprising such an arrangement. Prior art

[0002] A vehicle, particularly a motor vehicle, comprises a powertrain. Such a powertrain generally comprises at least one internal combustion engine and / or one electric motor and a cooling system for at least one such engine. The cooling system generally comprises at least one heat exchanger. Such a vehicle generally comprises a heating and / or air conditioning system for the vehicle's passenger compartment. Such a heating and / or air conditioning system generally comprises at least one heat exchanger. Such heat exchangers are generally arranged parallel to a vertical plane and transversely at the front of such a vehicle. Thus, the heat exchanger(s) benefit from an airflow during the vehicle's movement.

[0003] Given the high thermal performance now required for the engine(s) and / or the passenger compartment, such heat exchangers are larger. Consequently, their mass is generally increased.

[0004] Furthermore, such a vehicle generally comprises a body including a front face at least partially made of plastic and / or composite materials. Such a front face is then obtained by molding. Such a front face supports at least partially such heat exchangers.

[0005] However, the increase in volume and / or mass of such exchangers makes their integration complex at the front face level. Presentation of the invention

[0006] The present invention aims to provide an arrangement that overcomes the above drawbacks. In particular, the invention makes it possible, on the one hand, to reuse at least partially existing manufacturing molds for the manufacture of a front face adapted to larger heat exchangers and, on the other hand, to conceal fastening means behind stops on such a front face. Summary of the invention

[0007] To achieve this objective, the invention relates to an arrangement for a vehicle, the arrangement comprising: - an opening, in particular a hood for an engine compartment of such a vehicle, - a body element arranged at least partially opposite the opening in the closed position of the opening, in particular opposite a peripheral part of the opening, - a stop that comes into contact with the opening when the opening is in the closed position, - a secondary element, in particular a reinforcement of the body element, - a removable fastening means for attaching the secondary element to the body element, in particular a screw, the box element comprising a cavity, the cavity comprising a main opening, the main opening receiving the stop, the cavity comprising a secondary opening, the secondary opening receiving the fastening means, the secondary orifice and the main orifice being superimposed or substantially superimposed.

[0008] The main orifice may have a main axis and the secondary orifice may have a secondary axis, the main axis being able to intersect the area of ​​the main orifice.

[0009] The main axis and the secondary axis may be coincident or substantially coincident.

[0010] The main orifice can be tapped and the stop can be threaded so as to allow adjustment of the stop relative to the body element by screwing / unscrewing.

[0011] The arrangement may include a means for receiving the stop, the receiving means being able to be arranged in the main orifice, the receiving means being able to include a means for adjusting relative to the stop or relative to the main orifice, in particular of the thread-tapping type.

[0012] The case element can be made of plastic and / or composite material.

[0013] The secondary element may be made of metallic material, in particular steel.

[0014] The secondary element may comprise several parts assembled together by fastening means, in particular of the screw-nut type or rivets.

[0015] The arrangement may include a cross member extending transversely, in particular a cross member intended to be arranged behind a front bumper of such a vehicle, and the secondary element may be fixed to the cross member.

[0016] The arrangement may include an exchanger extending in a vertical and transverse plane, or substantially in a vertical and transverse plane, the exchanger being able to be fixed on the cross member and on the secondary element.

[0017] The invention further relates to a motor vehicle comprising an arrangement as defined above. Presentation of the figures

[0030] The direction in which a vehicle, particularly a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a right-handed coordinate system XYZ is used in which X is the longitudinal direction in the front-to-back direction of the vehicle, i.e., directed towards the rear, Y is the transverse direction directed to the right, and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the backward direction.

[0031] As illustrated in [Fig.1], a vehicle 1, in particular a motor vehicle, includes at least one engine 7. The engine 7 is, for example, of the internal combustion engine type, or electric, or even hybrid.

[0032] Vehicle 1 includes an arrangement 2.

[0033] As illustrated in [Fig. 2], the vehicle 1, or the arrangement 2, includes a cross member 9 extending transversely or substantially transversely. Preferably, the cross member 9 is intended to be arranged behind a front bumper 101 of the vehicle 1.

[0034] The vehicle 1, or the arrangement 2, further comprises an opening 3. Preferably, as illustrated in [Fig. 1], the opening 3 is an access hood to an engine compartment 35 of the vehicle 1. The vehicle 1, or the arrangement 2, further comprises a body element 6 arranged at least partially opposite the hood 3 in the closed position of the hood 3. The body element 6 extends transversely or substantially transversely, preferably behind the front bumper 101. For example, the body element 6 is of the "technical front face" type. By "technical front face" is meant a frame intended to support, bear, or fix parts of the vehicle. Unlike the bumper 101, the technical front face is not visible during normal use of the vehicle, i.e., once the hood 3 is closed. Preferably, the body element 6 is opposite a peripheral part 4 of the hood 3 in the closed position.The closed position of the hood 3 preferably means that the engine compartment 35 is no longer accessible through an opening obstructed by the closed hood 3.

[0035] The arrangement 2 further includes a stop 30 that contacts the hood 3 in the closed position. The stop 30's function is, in particular, to stop the hood at the end of its travel. Preferably, the stop 30 includes a damping coating or is made from a damping element. Thus, the stop 30 dampens, reduces noise, prevents a slamming sound when the hood 3 closes against the body panel 6, and allows for an optimal gap between the hood 3 and the body panels adjacent to the hood in the closed position.

[0036] As illustrated in particular in Figures 3 to 9, the arrangement 2 further includes a secondary element 8. Preferably, the secondary element 8 is a reinforcement of the body element 6.

[0037] Preferably, the body element 6 is made of plastic and / or composite material. Preferably, the secondary element 8 is made of metallic material, in particular steel. Thus, the material of the secondary element 8 contributes to making the secondary element 8 rigid, which in turn makes the body element 6 more rigid. Furthermore, the arrangement 2 further includes a removable fastening means 20 for attaching the secondary element 8 to the body element 6. For example, the fastening means 20 is a screw, or includes a screw, or is a screw-nut system. For example, as illustrated in the [Fig. 10], a screw 22 cooperates with a nut 21. The nut 21 is, for example, welded to the secondary element 8, or held in position relative to the element 8 in some other way. In this case, the screw-nut system 22, 21 sandwiches the body element 6 and the secondary element 8 between the head of the screw and the nut to secure them to each other. For example, two removable fastening means 20 are provided between the body element 6 and the secondary element 8 at the upper part of these elements 6, 8.

[0038] The body element 6 comprises a recess, a cavity 60. The cavity 60 comprises a main opening or hole 61, preferably circular. The main opening 61 receives the stop 30. The cavity 60 comprises a secondary opening or hole 62, preferably circular. The secondary opening 62 receives the fastening means 20. Note that the secondary opening 62 and the main opening 61 are superimposed or substantially superimposed. As will be explained later, the free main orifice 61, without the stop 30, allows access to the secondary orifice 62, or even allows a fastening means 20 to pass at least partially through the main orifice 61 to be inserted into the secondary orifice 62. In addition, a tool, such as a screwdriver for example, can be introduced through the main orifice 61 to operate, in particular to screw or unscrew, the fastening means 20 introduced into the secondary orifice 62.

[0039] Preferably, the secondary orifice 62 is such that the head of the screw 22 rests around the secondary orifice 62.

[0040] Preferably, the secondary element 8 is fixed at the top on the body element 6 and at the bottom on the cross member 9, as illustrated in [Fig.2].

[0041] For example, the secondary element 8 comprises two legs 81 extending substantially vertically, for example parallel to each other. Advantageously, the secondary element 8 then comprises several parts 81, 82, 83 assembled together by fastening means 84, 85 of the screw-nut type or rivets, for example. As illustrated in particular in [Fig. 3], the secondary element 8 comprises, for example, an upper part 82, of the cross member type, extending transversely or substantially transversely. The secondary element 8 also comprises, for example, a lower part 83, of the cross member type, extending transversely or substantially transversely. The upper part 82 is connected, fixed, to the two legs 81, for example by means of screw-nut fastening means 84. The lower part 83 is connected, fixed, to the two legs 81, for example by means of fixing means 85 of the screw-nut type.For example, parts 82, 83 are flat, i.e., rectangular in section and of small thickness. For example, legs 81 are obtained from a U, preferably bent to facilitate assembly with upper and lower parts 82, 83.

[0042] Preferably, as illustrated in Figures 4, 8 and 9, the secondary element 8 It also includes a tab 87 extending substantially in a longitudinal and transverse plane. The tab 87 preferably extends rearward from the upper part 82. Advantageously, the tab 87 includes at least one hole, or even several holes, facilitating its attachment to the body element 6. The holes, for example two in number, receive fastening elements 88, for example two screws or bolts, as illustrated in [Fig. 8]. Thus, the tab, extension, or plate 87 aims to secure the upper part 82 of the secondary element 8 to the body element 6, thereby stiffening the body element 6 and ensuring a connection between the two elements 6 and 8.

[0043] The vehicle or arrangement includes at least one heat exchanger or radiator 5. The heat exchanger(s) are, for example, dedicated to the cooling and / or heating of the engine(s) 7 and / or to the heating and / or air conditioning of a passenger compartment 100 of the vehicle.

[0044] Preferably, the heat exchanger(s) 5 extend parallel to a vertical and transverse plane, or substantially parallel to a vertical and transverse plane. The heat exchanger 5 is then preferably fixed to the cross member 9, for example under the cross member 9, and / or to the secondary element 8, for example by means of holes or openings 86 provided on the upper part 82, as illustrated in [Fig. 3].

[0045] Preferably, the main orifice 61, for example with a circular cross-section, has a main axis AP and the secondary orifice 62, for example with a circular cross-section, has a secondary axis AS. For example, the secondary axis AS intersects the area of ​​the main orifice 61, as illustrated in [Fig. 10]. Alternatively, or in addition, the main axis AP intersects the area of ​​the secondary orifice 62 (configuration not shown). By "intersect," it is understood that the axis passes through the area or surface delimited by the perimeter of the intersected orifice. Optionally, the main axis AP and the secondary axis AS coincide, or are substantially coincident (configuration not shown).

[0046] It should be noted that if the main orifice 61 has a large area, the positioning of the axes AS, AP can be arbitrary. Indeed, if the main orifice 61 has a large area, access to the fastening means 20 for a tool intended to cooperate with this fastening means is easy. Furthermore, the insertion of a part of the fastening means 20, for example a screw 22, through the main orifice 61 is also possible.

[0047] For example, the main orifice is tapped and the stop is threaded so as to allow the tapping of the main orifice and the thread of the stop to cooperate. Thus, adjustment of the stop relative to the body element by screwing / unscrewing is provided. For example, this adjustment is made along the main axis of the orifice in the case of threads centered on this main axis (embodyment not shown).

[0048] Preferably, as illustrated in Figures 10 and 11, the arrangement 2 further includes a receiving means 10 for receiving the stop 30. The receiving means 10 is for example provided with a shoulder 12. For example, the receiving means 10 is of the type cylindrical bored and shouldered ring. Preferably, this cylindrical shouldered ring is glued, attached, press-fitted, or welded by being inserted into the main orifice 61 until its shoulder 12 contacts an external surface 63 of the cavity 60 of the body element 6. In this case, preferably, the receiving means 10 includes an adjustment means 11 for the stop 30. Preferably, this adjustment means is a tapped hole 13 formed in the bore of the ring 10 cooperating with a thread 33 formed on the stop 30. Thus, the adjustment of the stop 30 is made along the axis of the tapped thread 33, 13 between the receiving means 10 fixed on the body element 6 at the main bore 61 and the stop itself.

[0049] Thanks to the solution, although the body element 6 is made of plastic and / or composite material to reduce its weight, its reinforcement 8 arranged at the front provides it with greater rigidity. This increased rigidity allows the body element 6 to support, at least partially, a radiator or a group of radiators 5 that is substantial in terms of volume and / or mass. Thus, the solution allows the integration of large radiators capable of providing high cooling and / or heating performance for vehicles with internal combustion, hybrid, or electric engines. Furthermore, such a group of radiators may include means for cooling or air conditioning and / or heating the vehicle's passenger compartment 100.

[0050] The solution is particularly compact, which allows for the integration of large radiators without requiring space to be freed up in the engine compartment for such integration.

[0051] Since the secondary reinforcement element 8 is removable from the body element 6, the solution offers easier access. This ease of access is further enhanced by the element 8 being composed of elements 81, 82, and 83, preferably also assembled in a removable manner. Attaching the simply designed reinforcement 8, preferably made of steel, to the one-piece body element 6 simplifies the design of element 6. For example, the body element can be manufactured by molding using existing, modified molds, rather than creating entirely new ones. In other words, the technical front end of the vehicle, including the plastic element 6, is reinforced without creating specific molds. This results in significant cost savings and allows the solution to be adapted to several vehicle models.

[0052] Although the solution requires fasteners between element 6 and its reinforcement 8, the solution also allows these fastening means 20 for connecting the two elements 6 and 8 to be concealed. Indeed, the fastening means 20, which would be visible from above when the engine compartment hood 3 is opened, are hidden by the stops 30. Although the stops 30 are, for example, four in number to precisely adjust the gaps between the hood and adjacent body parts, and particularly for the quality perceived by the customer, for example only two stops arranged at the front are used to hide the means of fixing 20. Alternatively, a single stop, three or even four, or more where appropriate, can be used to hide fixings.

[0053] Note that the metal reinforcement 8 primarily reinforces an upper area of ​​the plastic support 6. As a reminder, the legs 81 are assembled, for example, by screwing, approximately in the middle of the upper part 82 and approximately in the middle of the lower part 83 in the transverse direction. The two fastening means 20 between the two elements 6, 8 are, for example, arranged further apart with respect to a vertical and longitudinal median plane of the vehicle. As a reminder, the two fastening means 20 are concealed under the stops 30 of the hood 3.

[0054] Note that the reinforcement 8 is first attached to the body element 6 using the fastening means 20 before assembling the stops 30. More precisely, the upper part 82 is preferably brought into contact with the lower walls of the two cavities 60 of the element 6 ([Fig. 5]). Thus, as illustrated in [Fig. 10], the upper part 82 of the reinforcement 8 is placed below the cavity 60, that is, in contact with a lower external surface 64 of each cavity. Preferably, the fastening means 20 includes a nut 21, for example, pre-welded or crimped onto the upper part 82. The screw 22 can then be inserted into the main hole 61, or even into the adjustment means 11 if it is already positioned or fixed within the main hole 61 and if the size of its bore allows it.Alternatively, the screw 22 can be approached by passing it through the cavity, that is, by passing the screw from the rear of the cavity 60, which is preferably open on that side, as illustrated in [Fig. 11]. The screw 22 is then inserted into the secondary opening 62 and screwed into the nut 21. Preferably, each screw 22 passes through the opening 61 before passing through the plastic support 6 and screwing into the nut 21 on the cross member reinforcement 8. The front face support 6 is then sandwiched between the head of each screw 22, or an interposed washer 23 ([Fig. 11]), and the upper part 82 of the flat metal reinforcement 8, as illustrated in particular in Figures 10 and 11.

[0055] Note that the solution allows a tool, for example a screwdriver or socket, to be inserted through the main opening 61, the openings 61 and 62 being superimposed, opposite each other, or partially opposite each other, so as to allow this screwing. Preferably, unscrewing the screws 22 is also possible and, if necessary, retrieval of the screws, possibly manually via the opening 61 or by means of a magnetic tool, or even via the cavity 60.

[0056] Once the screws 22 are tightened, the stops 30 can then be mounted within the adjustment means 11, if applicable. As a reminder, preferably, each stop 30 includes a thread 33 and each means 11 includes a tapped hole 13 suitable for The stops cooperate with the threads of the stop. For installation, the stop is screwed into its adjustment mechanism. Then, to adjust the stops, screwing the stop in, for example, pushes it down, while unscrewing it raises it. This allows for precise adjustment of the clearance between the hood 3 and other adjacent body panels and / or prevents the hood from slamming against the body panel 6 when closed. In short, the hood stops are installed last, which allows the holes 61 for attaching them to the body panel 6 to be used for inserting the screws 22 and tightening them with a tightening tool. Thus, the solution allows for maintaining a hood stop adjustment range due to the presence of the cavity 60 into which the threaded part 33 of the stop opens and possibly the receiving means 10, while having the screw head 22 in the cavity 60 of the plastic front panel support 6.

[0057] Having the fixing screws 22 accessible from the top of the vehicle is advantageous for factory assemblers. This arrangement is more ergonomic and less tiring. Furthermore, thanks to the stop which acts as a cover once installed, these fixing screws 22 of the reinforcement 8 are invisible. This creates the impression that the technical front panel comprising elements 6 and 8 is a single piece and / or without any fasteners between the plastic and metal parts. This contributes to a very satisfactory perceived quality. Any corrosion and / or change in color or appearance of the screws over time is not visible.

[0058] Alternatively, in an embodiment not shown, a clip, for example a fir tree type clip, is attached from bottom to top to fix the secondary metal element 8 to the plastic body element 6. In this case, the nut 21 under part 82 is eliminated. Note that the less aesthetically pleasing part of such a fir tree clip, i.e., the part that grips the material, is then located within the cavity 60 and is therefore hidden under the stop. When disassembling, access through the opening 61 allows the clip to be pressed down to remove it.

[0059] Thanks to this solution, it becomes possible to dismantle the technical front panel, in particular the secondary element 8, by removing the two screws 22 hidden by the stops 30 of the hood and the screws 85, 84 at the bottom and top. This dismantling is particularly feasible after removing the grille.

[0060] The solution allows intervention on the front face without dismantling the radiator(s) which may require draining, or even purging during subsequent refilling, and / or a "vacuum draw".

[0061] For example, a change of headlight or a change of grille, or even a change of front end, are facilitated by the solution.

[0062] As a side note, the solution therefore achieves the desired objective of facilitating the integration of larger and / or heavier heat exchangers at the front face of vehicle and has the advantage of being able to be adapted for a utility vehicle, or even a truck, a bus, a coach, an agricultural vehicle, a lifting device or any other machine.

[0063] Note that although the solution has been described for a front-mounted engine compartment cover, it can be adapted to a rear trunk lid or a rear engine compartment cover. In such cases, the arrangement may not include a radiator and may include at least one cavity for attaching a component while also receiving a hood stop that conceals the attachment.
