Description

Description Title of the invention: Arrangement for a vehicle comprising a device for supporting at least one component equipping the structure front of the vehicle

[0001] = The invention relates to an arrangement for a vehicle comprising a device for support configured to support at least one component to be equipped in the structure front of the vehicle. The invention also relates to a support device intended for such an arrangement. The invention also relates to a vehicle equipped with an arrangement and / or a support device according to the invention. The invention finally relates to a method of mounting an arrangement according to the invention.

[0002] In the automotive industry, the evolution of vehicles from traditional engines tional, with thermal engines, towards electric or hybrid engines has been ac- accompanied by a considerable increase in their mass due to the presence of propulsion batteries, or motor batteries. This results in the structures of body, designed for thermal vehicles, cannot be used at the same to produce vehicles with hybrid or electric engines without degrade the safety features offered by the vehicle. Indeed, the energy to be absorbed in the event of a frontal impact is all the greater as the mass of the vehicle increases and an increase in forces can be observed during an impact frontal.

[0003] In the case of thermally powered vehicles, it is known to reinforce the front structure of the vehicle by means of reinforcement parts, such as tie rods, screwed on the cradle and the body structure in order to compensate for a lack of rigidity of the front structure. Such an arrangement is nevertheless not sufficient to prevent damage formations of the front structure of the vehicle in the case of motorized vehicles electric or hybrid, on the one hand due to the increase in their mass and on the other hand because they are unsuitable for protecting high voltage electrical systems.

[0004] — In addition, the transition to electric or hybrid engines is accompanied of a need to redevelop the front structure of vehicles in order to integrate additional components but also to ensure the protection of the various systems and interfaces present, such as hydraulic systems, involved in the thermal treatment of propulsion batteries and / or the passenger compartment, and systems electrical, in particular high voltage power supply supplying the batteries of propulsion.

[0005] — It is known to equip the front structure of vehicles with supports, configured to support various components fitted to the front panel. Such supports are class- ically mounted on the subframe and / or the body structure of the vehicle, for example by fixing to reinforcement parts and / or tie rods. Such arrangements are nevertheless accompanied by a multiplication of references and, by extension, an increase in the dispersion and the chain of dimensions. In addition, interventions on the vehicle, for example in the context of the replacement or repair of a component or system located on the front face, can prove to be complex and time-consuming in that they may require the extraction of systems and components not requiring specific intervention but hindering access to the targeted component or system. The present invention falls within this context and aims to propose an arrangement for stabilizing the front structure of the vehicle in the event of a frontal impact. The invention also aims to propose an arrangement allowing better accessibility to the various components and systems equipping the front structure of the vehicle. The invention relates to an arrangement for a vehicle comprising a cradle, a body structure and a support device configured to support at least one component to be equipped in a front structure of the vehicle, the support device comprising: - a planar body configured to support the at least one component; - a pair of tie rods configured to be fixed to the cradle and the body structure - a crosspiece connected to the body and connecting the tie rods together. The support device is configured to be fixed to the cradle and to the body structure from below so as to extend into contact with lower surfaces of the cradle and the body structure, said lower surfaces being configured to be turned towards the ground within the vehicle, the support device being fixed via a plurality of fixing points included in at least the tie rods. In particular, the body, the crosspiece and the tie rods can form a single unit. The arrangement may further comprise at least one additional fixing fin for the body on the body structure. The arrangement may further comprise a heating housing, in particular of the PTC type, said heating housing being able to be mounted on the body by means of at least one fixing means, such as a clip and / or a screw. The arrangement may further comprise a protective fairing for a battery, the support device comprising a plurality of attachment points for said fairing. The arrangement may comprise at least one pipe for circulating a fluid, in particular a liquid such as water or a cooling fluid, the support device comprising at least one zone for fixing said at least one pipe. The arrangement may comprise at least one electrical power cable, in particular for supplying a drive and / or service battery, the support device comprising at least one zone for fixing said cable. The invention also relates to a vehicle support device configured to support at least one component to be equipped in a front structure of the vehicle, the support device comprising: - a planar body configured to support the at least one component; - a pair of tie rods configured to be fixed to a cradle and a body structure; - a crosspiece connected to the body and connecting the tie rods together. The support device is configured to be fixed from below to the cradle and to the body structure from below so as to extend in contact with lower surfaces of the cradle and the body structure, said lower surfaces being configured to be turned towards the ground within the vehicle, the support device being fixed via a plurality of fixing points included in at least the tie rods. The support device may further comprise at least one of: - at least one additional fixing fin configured to allow the body to be fixed to the body structure; - a plurality of attachment points of a protective fairing of a battery; - at least one fixing zone for at least one fluid circulation pipe; - at least one area for fixing at least one electrical power supply cable, in particular for supplying a battery. The invention also relates to a motor vehicle, in particular an electrically powered vehicle, comprising an arrangement and / or a support device as described above. The invention finally relates to a method for mounting an arrangement according to the invention within a vehicle, the method comprising fixing the support device from below to the cradle and to the body structure by means of a plurality of fixing points included in at least the tie rods so as to extend into contact with the lower surfaces of the cradle and the body structure so that the support device is at least partially interposed between the cradle and the body structure on which it is fixed on the one hand and the ground on which the vehicle rests on the other hand. Other details, characteristics and advantages will emerge more clearly on reading the detailed description given below, for informational and non-limiting purposes, in relation to the various examples of embodiment illustrated in the following figure: [Fig. 1] is a simplified schematic representation seen from below of an arrangement according to the invention, comprising a support device. [Fig.2] is a schematic representation of part of the arrangement seen from above. [Fig.3] is a schematic perspective representation of part of the arrangement. [Fig. 1] schematically illustrates an exemplary embodiment of an arrangement 1 according to the invention arranged at the front structure of a vehicle 2, in particular a motor vehicle 2. The vehicle 2 considered is particularly a motor vehicle 2 with an electric motor. Alternatively, the arrangement 1 according to the invention can be applied mutatis mutandis to vehicles 2 with a thermal motor comprising a thermal engine or to vehicles 2 with a hybrid motor comprising a thermal engine and at least one propulsion battery, also referred to as a drive battery. Said vehicle 2 can, for example, be a private vehicle or a utility vehicle. Figures 1 to 3 illustrate an exemplary embodiment of the arrangement | according to the invention. By convention in the description below, the direction in which the motor vehicle 2 moves in a straight line is defined as being the longitudinal direction X. The direction perpendicular to the longitudinal direction and located in a plane parallel to the ground is called the transverse direction Y. The direction perpendicular to the directions X and Y is called the vertical direction Z. Thus, a direct reference frame XYZ is defined, represented in [Fig. 1], conventionally implemented in the automotive environment. The terms “top” and “bottom” or “upper” and “lower” are understood in their general sense, the terms “bottom” and “lower” designating a greater proximity to the ground. Also, the terms “first” and “second” are intended to distinguish similar elements and not to define a hierarchy within said elements. Generally, the arrangement | according to the invention comprises a cradle 3, a body structure 4 and a support device 5 configured to support at least one component 6 to be equipped in the front structure of the vehicle 2. The term “body structure” refers in particular to classic body structure elements 4 such as side members, cross members or stretchers conventionally fitted to vehicles 2. Generally, the support device 5 comprises at least one body 7, a pair of tie rods 8 and a cross member 9. The term "tie rod" is understood to mean in particular a reinforcing and / or connecting element. It is understood that, throughout the description below, any characteristic described in relation to the support device 5 included in the arrangement 1 according to the invention may also extend to a support device 5, as such, for use in an arrangement 1 and / or in a vehicle 2 according to the invention. The body 7 is planar and is configured to support at least one equipped component 6 in the front structure of the vehicle 2. In particular, as illustrated, the component 6 considered may be a heating box, in particular of the PTC type, i.e. with Positive Temperature Coefficient. Such a heating box may in particular be intended for the heat treatment of the passenger compartment of the vehicle 2. Furthermore, said component 6 may be included in the arrangement 1 according to the invention. In order to allow the fixing of the component 6 considered, the body 7 comprises at least one fixing means 71. Preferably, the body 7 comprises a plurality of said fixing means 71. For example, the body 7 may comprise fixing means 71 of the clip and / or screw type. In the particular example illustrated, the body 7 has a substantially rectangular shape in which a proximal side is connected to the crosspiece 9 and is configured to present, along the longitudinal direction, the greatest proximity to the cradle 3 within the arrangement 1. The rectangular shape further comprises a distal side, opposite the proximal side along the longitudinal direction, and two lateral sides, connecting the proximal side and the distal side to each other. The pair of tie rods 8 is configured to be fixed on the cradle 3 on the one hand and on the body structure 4 on the other hand. The tie rods 8 are connected to the body 7 via the cross member 9. Furthermore, the tie rods 8 are connected to each other via this same cross member 9 so as to ensure the rigidity of the support device 5 along the transverse direction Y when the arrangement 1 is equipped within the vehicle 2. It is understood that, throughout the description below, any description made with reference to one of the tie rods 8 may extend to all of the tie rods 8 of the pair. The tie rod 8 has the shape of an elongated part, in particular at least partly rectilinear, having two ends. The tie rod 8 is in particular connected to the cross member 9 at a first end 81 while a second, opposite end 82 extends towards the rear of the vehicle 2. In this case, the second end 82 of the tie rod 8 is a free end configured to be fixed to the body structure 4, for example to a front cross member of the body structure 4, not shown, in particular a front floor cross member. In particular, the cross member 9 is configured to extend transversely, or substantially transversely, within the vehicle 2, that is to say parallel to the transverse direction Y. The tie rod 8 extends transversely to the cross member 9, that is to say along a straight line intersecting a direction of extension of said cross member 9.Preferably, the tie rod 8 extends towards the rear of the vehicle 2 along a direction distinct from the longitudinal direction X so that it forms a non-right angle relative to the cross member 9, in particular towards the exterior of the vehicle 2 along the transverse direction Y. The tie rod 8 also preferably has the shape of a profile. In particular, the tie rod 8 has, along the vertical direction Z, a structure curved and / or inclined and / or stepped. In this case, the first end 81 thus has a vertically lower position than that of the second end 82. Preferably again, the tie rod 8 has a limited height so as not to affect the ground clearance of the vehicle 2. Here, the term “height” is understood to mean a dimension measured along the vertical direction between the position of the first end 81 and a projection of the projection of the second end 82. The tie rods 8 are arranged on either side of the body 7 along the transverse direction Y so that they define a passage at the level of which the body 7 extends. In particular, the support device 5 is configured to be fixed to the cradle 3 and to the body structure 4 by means of a plurality of fixing points included in at least the tie rods 8. Each tie rod 8 thus comprises an orifice capable of receiving a fixing member 83 of the tie rod 8 in question, and by extension of the support device 5, on the cradle 3 or the body structure 4. For example, the fixing member 83 may be a screw or a screw / nut assembly. Preferably, each tie rod 8 comprises at least two separate fixing points. In particular, in the example as set out above, the first end 81 of the tie rod 8 is fixed to the cradle 3 and the body structure 4, superimposed on each other, while the second end 82 is fixed to the body structure 4 so as to distribute the fixing points along the tie rod 8. The arrangement | according to the invention, particularly the support device 5, is advantageously configured so that the support device 5 is fixed to the cradle 3 and to the body structure 4 from below. By "from below" is meant that the support device 5 extends in contact with the lower surface 301 of the cradle 3 and the lower surface 401 of the body structure 4, said lower surfaces 301, 401 being configured to be turned towards the ground within the vehicle 2. In other words, when the support device 5 is mounted in the vehicle 2, at its fixing points it is interposed between the cradle 3 and the body structure 4 on the one hand and the ground on which the arrangement 1 and / or the vehicle 2 is arranged along the vertical direction Z. Thus, the support device 5 has a positioning lower than portions of the cradle 3 and the body structure 4 on which it is mounted.As further explained below with reference to the assembly method according to the invention, the support device 5 can thus be assembled from below on the cradle 3 and the body structure 4, by intervention of a technician under the vehicle 2. The fixing points are thus accessible from under the vehicle 2, facilitating the assembly and disassembly of any element or component fixed on the support device 5. As previously explained, the crosspiece 9 extends along the transverse direction Y so as to connect the tie rods 8 of the pair together. As a result, the cross member 9 indirectly connects opposite parts and / or elements of the body structure 4 along the transverse direction Y. The cross member 9 and the tie rods 8 thus have the function of reinforcing the cradle 3, in particular in the event of a frontal impact with the vehicle 2. Within the vehicle 2, the cross member 9 is arranged so as to be interposed between the cradle 3 and the body 7 of the support device 5 along the longitudinal direction X. In this sense, optionally but preferably, the cross member 9 and the tie rods 8 of the pair of tie rods 8 form a single-piece assembly. By "single-piece" is meant that the cross member 9 and the tie rods 8 cannot be separated from each other without resulting in the degradation or even destruction thereof. In a particular, preferential manner, the body 7, the cross member 9 and the tie rods 8 form a single-piece assembly. Such a support device 5 thus advantageously allows the reinforcement of the part, the reduction of the dimension chain and the reference number and, consequently, a simplification of the assembly of the support device 5 within the vehicle 2. In particular, all or part of the support device 5 may be made of sheet metal, aluminum and / or steel, and may, for example, be stamped, welded and / or folded. Optionally, the support device 5 may further comprise at least one fin 72 for additionally fixing the body 7 to the body structure 4. In this case, the support device 5 comprises a pair of fins 72. In particular, said fins 72 extend parallel, or substantially parallel to the crossmember, towards the outside of the vehicle along the transverse direction Y. The at least one fin 72 also extends at a non-zero distance from the second end 82 of the adjacent tie rod 8. In particular, the at least one fin 72 has a stepped structure such that a free end thereof extends in a plane distinct from a plane in which the body 7 is inscribed. For example, the free end of the at least one fin 72 and the second end 81 of at least one of the tie rods 8 may be inscribed in the same plane. Also, in the case of vehicles 2 with hybrid or electric motors, i.e. comprising at least one drive battery, it is known to provide, within the front structure of the vehicle 2, a location intended for a battery protection fairing. The term “fairing” means a profiled envelope covering or surrounding at least partially the battery in order to ensure its protection. The support device 5 may furthermore, optionally but preferably, be configured so as to comprise at least one attachment point 10 of such a fairing, in particular a plurality of attachment points of said fairing. In the example illustrated, the support device 5 comprises four attachment points 10 of the protective fairing. The arrangement 1 according to the invention may thus advantageously comprise a protective fairing of a battery, not shown, particularly of a drive or propulsion battery, mounted directly on the support device 5. The attachment points 10 of the protective fairing are in particular included in the cross member 9 and / or the pair of tie rods 8. In this case, the cross member 9 comprises two attachment points 10 of the protective fairing. In particular, said attachment points 10 are distributed along the cross member 9 so as to extend, along the transverse direction Y, on either side of the body 7. Also, the pair of tie rods 8 may comprise and / or carry a plurality of attachment points 10 of the protective fairing. In the example illustrated, each tie rod 8 carries a lateral extension 84 comprising one of the attachment points 10 of the protective fairing. The lateral extensions 84 are in particular carried by the second end 82 of each tie rod 8 and are configured to extend towards the outside of the vehicle 2 when the arrangement 1 is equipped therein. Preferably, each lateral extension 84 and tie rod 8 form a single-piece assembly. Optionally but preferably, the support device 5 may advantageously comprise at least one zone for fixing at least one fluid circulation pipe 11. For example, such a circulation pipe 11 may be configured to allow the circulation of a liquid such as water or a cooling fluid. In particular, such a circulation pipe 11 may be intended to supply a heating, ventilation and air conditioning (HVAC) installation, or a heat treatment system for at least one element of the electric powertrain. The arrangement 1 according to the invention may also comprise at least one fluid circulation pipe 11. In the example illustrated, a plurality of fluid circulation pipes 1 | are connected to the support device 5 and / or to the component 6, here the heating housing. For example, as illustrated for a first pipe 11a and a second circulation pipe 11b, an outer periphery of the circulation pipe 11 considered may comprise a finger or a pin configured to be inserted into an orifice 73 included in the support device 5. Alternatively or additionally, the fixing of the circulation pipe 11 considered on the support device 5 may be carried out by means of a fixing element 12, for example, as illustrated, comprising a ring configured to at least partially surround said pipe 11 and a base capable of cooperating with the support device 5, for example with an orifice 73 as explained above. Optionally, said base may comprise a fixing mechanism such as a clip. In the example illustrated, the fixing of the at least one pipe 11 can be carried out at the level of at least one of the fins 72. In particular, the fins 72 of the support device 5 comprise at least one orifice 73 capable of receiving a finger, pin and / or a fixing element 12 as previously explained. Additionally or alternatively, the fixing of the at least one pipe 11 can be achieved by direct or indirect connection to the body 7 of the support device 5. For example, as illustrated, the body 7 can carry a tab 74 comprising at least one orifice 73 capable of receiving a finger, pin and / or a fixing element 12 as previously explained. Preferably, such a tab 74 comes from the lateral side of the body 7. Also, such a tab 74 can be arranged between at least one of the fins 72 and the crosspiece 9 along the longitudinal direction X. According to an example not shown, implemented alternatively or additionally to the previous examples, the at least one pipe 11 can be fixed to the support device 5 at the level of the crosspiece 9 Optionally but preferably, the support device 5 according to the invention may advantageously comprise at least one zone for fixing an electrical power supply cable 13. For example, the power supply cable 13 in question may be a low-voltage power supply cable 13, for example 12V, for supplying the service battery, and / or may be a high-voltage power supply cable 13, for example 400V, in particular for the drive battery. The arrangement 1 may thus also comprise at least one electrical power supply cable 13. In the example illustrated, a plurality of electrical power supply cables 13 are fixed to the support device 5, a first cable 13a being a 12V power supply cable and a second cable 13b being a 400V power supply cable. Similar to what has been explained previously with reference to the pipe 11 for circulating a fluid, an outer periphery of at least one of said cables 13 may be configured to cooperate with a hole 75 included in the support device 5. Alternatively or additionally, the fixing of the cable in question may be carried out by means of a holding element 14, similar to the fixing element 12 as described previously. For example, the holding element 14 may comprise a ring configured to at least partially surround the cable and a base capable of cooperating with the support device 5, in particular by means of a clip. In the illustrated example, the fixing of the first cable 13a is carried out at the crosspiece 9. Alternatively or additionally, the fixing of such a cable can be carried out at at least one of the fins 72. Additionally or alternatively, as shown for the second cable 13b, the fixing of the at least one cable can be carried out by direct or indirect connection to the body 7 of the support device 5. For example, as illustrated, the body 7 can carry a tab 76 configured to allow the fixing and holding of at least one of the cables, for example by means of a screw or a staple. The tab 76 extends in particular transversely, particularly orthogonally to the body 7. It extends in particular to the at least partly vertically, upwards. The tab 76 is, preferably, issued from the distal side of the body 7 so as to be the furthest from any contact in the event of a frontal impact. Also, the tab 76 may extend into contact with the component 6 and / or be configured to form a stop for said component 6 along at least one direction, in particular along the longitudinal direction X, for example in the event of a frontal impact. Such examples of attachment advantageously make it possible to limit the movements of the electrical cables within the front structure, thus limiting the risks of fretting corrosion, or "fretting corrosion" in English, Optionally but preferably, the arrangement 1 may comprise connecting elements 15 configured to hold together different circulation pipes 11 and / or different electrical power cables 13. In addition to the reinforcement of the cradle 3 and the support of a component 6 of the front structure of the vehicle 2, here of the heating box, the support device 5 can thus optionally allow, on the basis of the different options set out previously: - the attachment of the battery protection fairing; and / or - the fixing of at least one pipe 11 for circulating a fluid; and / or - the fixing of at least one electrical power cable 13. The support device 5 and the arrangement 1 according to the invention thus advantageously allow simultaneous and simplified access to different devices and systems equipping the front structure of the vehicle 2, in this case selected from among the heating box, a hydraulic system, an electrical system and the protective fairing. The support device 5 further allows simplified mounting of the support device 5 and the aforementioned devices and systems within the vehicle 2, on the one hand by reducing the coasting chain and dispersions, as explained above, and on the other hand by allowing mounting and fixing of the support device 5 from below in the vehicle 2. In this sense, the invention also relates to a method for mounting the arrangement 1 according to the invention within a vehicle 2. Such a method generally comprises fixing the support device 5 from below on the cradle 3 and on the body structure 4 by means of a plurality of fixing points. The fixing points are particularly included in at least the tie rods 8 and the support device 5 is arranged so as to extend in contact with the lower surfaces 301, 401 of the cradle 3 and the body structure 4. The support device 5, particularly at least the pair of tie rods 8, is thus at least partially interposed between the cradle 3 and the body structure 4 on which it is fixed on the one hand and the ground on the other hand along the vertical direction Z. In particular, the first end 81 of the tie rods 8 can be fixed to the cradle 3 and the body structure 4 at a vertically superimposed area of ​​the cradle 3. on the body structure 4. The second end 82 is, for its part, fixed on the body structure 4. Optionally, the method may comprise, after fixing the tie rods 8 of the support device 5 to the cradle 3 and the body structure 4, the fixing of at least one of the additional fixing fins 72 to the body structure 4. Optionally, the method may comprise, prior to fixing the support device 5 to the cradle 3 and the body structure 4, fixing the protective fairing to the support device 5 via a plurality of fixing points and zones. Optionally also, the method may comprise, prior to fixing the support device 5 on the cradle 3 and the body structure 4, fixing the at least one pipe 11 for circulating a fluid on the support device 5. Optionally, the method may comprise, prior to fixing the support device 5 on the cradle 3 and the body structure 4, fixing at least one electrical power cable 13 on the support device 5. These principles apply in reverse order to allow disassembly of the arrangement according to the invention. The various components, devices and systems fixed to the support device 5 can thus be simultaneously installed in the vehicle via the support device 5, the latter forming a common platform. The same applies in the event of disassembly. The present invention thus proposes an arrangement and a support device allowing simultaneously the reinforcement of the front structure of the vehicle and the support of at least one component equipped on the front face of the vehicle. The arrangement and the support device according to the invention allow, in addition, simplified assembly and handling by reducing the number of references involved in the front structure of the vehicle and by allowing fixing from below on the cradle and the body structure. The support device and the arrangement according to the invention finally advantageously allow the securing and simplified access to different devices and systems of the front structure of the vehicle by centralizing at least part of their fixings at the level of the support device. The present invention cannot, however, be limited to the means and methods described and illustrated here and it also extends to any equivalent means or method and to any technically effective combination of such means insofar as they ultimately fulfill the functionalities described and illustrated in the present document.
