[0025] 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.

[0026] As schematically illustrated in [Fig. 1], a vehicle 1, preferably a motor vehicle, includes a small compartment 7. Preferably, the compartment 7 is arranged at the front of the vehicle 1. The vehicle 1 has a short front overhang, i.e., the distance D between the axle of a front wheel 8 of the vehicle 1 and a front end of the vehicle 1 is between 60 and 90 cm, for example equal to 75 cm.

[0027] Preferably, the vehicle 1 comprises a powertrain 9, for example electric, arranged at the rear. In this case, advantageously, the vehicle 1 comprises a means of transmitting torque to the rear wheels, i.e., the vehicle 1 is propelled in motion by propulsion.

[0028] The vehicle 1 comprises a chassis 6. The vehicle 1, or the chassis 6, comprises an arrangement 2 as will be seen later.

[0029] As illustrated in [Fig. 2], the arrangement 2 comprises a left side member 3 and a right side member 4. Preferably, the left and right side members are arranged at the front of the vehicle 1, i.e., they are front side members. Alternatively, the side members are arranged at the rear of the vehicle, i.e., they are rear side members (an embodiment not illustrated).

[0030] As illustrated in [Fig. 3], arrangement 2 still comprises at least one Left leg 31; 32 fixed to the left side member 3 and extending transversely towards a median plane M of the vehicle 1 (illustrated in [Fig.2]). The median plane M extends vertically and longitudinally, at the middle, or substantially at the middle, of the vehicle 1 in the transverse direction.

[0031] The arrangement 2 further includes at least one straight leg 41; 42 fixed to the right longitudinal member 4 and extending transversely towards the median plane M of the vehicle 1.

[0032] The arrangement 2 further includes a support 10 extending transversely between the left side member 3 and the right side member 4. As illustrated in Figures 6, 7, and 8, the support 10 includes a lower face 11, facing the ground or substantially facing the ground in the mounted position of the support 10. The lower face 11 is therefore oriented downwards or substantially oriented downwards. The support 10 includes an upper face 12, opposite the lower face 11, that is, oriented upwards or substantially oriented upwards.

[0033] In the illustrated embodiment, particularly in [Fig. 3], arrangement 2 comprises a first left leg 31 and a second left leg 32 fixed to the left spar 3. The first and second left legs 31, 32 are arranged one behind the other in the longitudinal direction while remaining spaced apart. Arrangement 2 further comprises a first right leg 41 and a second right leg 42 fixed to the right spar 4. The first and second right legs 41, 42 are then arranged one behind the other along the longitudinal direction while being distant from each other.

[0034] Preferably, the first and second left legs 31, 32 are fixed to the left side member 3 by welding and the first and second right legs 41, 42 are fixed to the right side member 4 by welding.

[0035] More specifically, the support 10 is attached below the left legs 31; 32 and below the right legs 41; 42. In other words, the support 10 is arranged under the first and second left legs and under the first and second right legs.

[0036] The support 10 is intended to support equipment 51; 52; 53; 54; 55 of the vehicle 1. Equipment is fixed above the support 10 or equipment is fixed below the support 10. Advantageously, as illustrated in particular in figures 4 and 5, some equipment is fixed below the support 10 and other equipment is fixed on the support 10.

[0037] As illustrated in [Fig. 7], the support 10 preferably includes at least one threaded hole or at least one nut 34, 44 fixed to the support 10 on each side in the transverse direction. Preferably, these are insert nuts, fixed to the underside 11 of the support 10, i.e., beneath the support 10. Advantageously, in the case of nuts, these nuts 34, 44 are welded to the support 10 so as to facilitate the engagement of screws within these nuts. These nuts 34, 44 are intended to contribute to the fixing of the support 10 relative to the respective lugs 31, 32, 41, 42.

[0038] Thus, to ensure the fixing of the support 10, the first and second left legs 31, 32 and the first and second right legs 41, 42 each include at least one respective hole 35, 45 referenced in dotted lines on the [Fig.3].

[0039] As illustrated in [Fig. 3], the arrangement 2 further includes screws 33. Preferably, a screw 33 passes through a hole 35 provided in the first left leg 31 and cooperates with a nut 34 fixed under the support 10. Preferably, a screw 33 passes through a hole 35 provided in the second left leg 32 and cooperates with a nut 34 fixed under the support 10. Preferably, a screw 43 passes through a hole 45 provided in the first right leg 41 and cooperates with a nut 44 fixed under the support 10. Preferably, a screw 43 passes through a hole 45 provided in the second right leg 42 and cooperates with a nut 44 fixed under the support 10.

[0040] In the illustrated embodiment, a single screw 33, 43 thus ensures the fixing of the support 10 with respect to a single tab 31, 32, 41, 42.

[0041] Advantageously, the support 10 is a folded and / or stamped sheet metal, for example made of steel. The thickness of the sheet metal used to obtain the support 10 is, for example, between 1 mm and 2 mm, or even between 1.5 mm and 1.75 mm. As illustrated in particular in [Fig. 8], the support 10 has a cross-section along a vertical and longitudinal plane in the overall shape of an inverted Omega, that is to say, with the head facing down. Indeed, as illustrated in figures 6, 8 and 9, the support 10 comprises substantially two U-shaped beams 13, 14 extending transversely downwards and connected to each other by a flat or substantially flat portion 15 extending substantially in a transverse and longitudinal plane.

[0042] Advantageously, folds and / or rounded and / or bossed and / or embossed 16 are provided at the level of each "beam" 13, 14 and at the level of the flat portion 15. Optionally, as illustrated in [Fig.7], the support 10 includes dropped edges 17, at least over a part of the length of the support extending in the transverse direction.

[0043] As illustrated in [Fig. 6], the support 10 includes vertically aligned holes 151, 152. The support 10 also includes nuts 161, 162 with axes common or substantially common to the axes of the holes 151, 152. The nuts 161, 162 are then fixed to the underside of the support 10, i.e., against the lower face 11, for example by welding. The holes 151, 152 opening at the respective nuts 161, 162 allow the equipment 51, 52 arranged on the support, i.e., above it, to be fixed. For this purpose, as illustrated in [Fig.3], screws 171 sandwich the equipment 51 between the heads of the screws 171 and the support 10 via the cooperation of the screws 171 with the nuts 161. For example, two screws 171, or three, or even four, are provided to cooperate with the same number of nuts 161.Similarly, screws 172 sandwich the equipment 52 between the heads of the screws 172 and the support 10 via the cooperation of the screws 172 with the nuts 162. For example, two screws 172, or three, or even four, are provided to cooperate with the same number of nuts 162.

[0044] The arrangement 2 preferably comprises equipment 51, 52, 53, 54, 55. For example, equipment 51 is a battery mounted here above the bracket 10. Battery 51 is advantageously a service battery, for example a lead-acid battery, preferably having a voltage across its terminals of approximately 12 volts. Alternatively, it may be another type of battery. For example, equipment 52 is a compressor for an air conditioning system 60 fitted to the vehicle 1. Equipment 52 is mounted above the bracket 10.

[0045] Preferably, as illustrated in [Fig. 7], the support 10 comprises screws 173 with a vertical axis passing through the support 10 and extending under the support 10. Preferably, as illustrated in [Fig. 7], the support 10 comprises screws 174 with a vertical axis passing through the support 10 and extending under the support 10. Preferably, as illustrated in [Fig. 7], the support 10 comprises screws 175 with a vertical axis passing through the support 10 and extending under the support 10. The screws 173, 174, 175 are advantageously fixed to the support 10, for example by welding. For this purpose, holes are, for example, pre-drilled in the support and the screws 173, 174, Screws 175 are inserted into these holes before being welded in place. Thus, screws 173, 174, and 175 act as studs or equivalent fasteners for securing equipment arranged below support 10. Nuts then cooperate with screws 173, 174, and 175 to secure equipment 53, 54, and 55. For example, three screws 173 and three nuts are used to secure equipment 53. For example, three screws 174 and three nuts are used to secure equipment 54. For example, three screws 175 and three nuts are used to secure equipment 55. Fewer or more screws, and the same number of corresponding nuts, may also be suitable.

[0046] Preferably, the equipment 53 is a solenoid valve, for example with seven ports, and is fixed below the support 10. Preferably, the equipment 55 is a component of the air conditioning system 60. The equipment 55 is fixed below the support 10. Preferably, the equipment 54 is a heater for a heating system 70 for a passenger compartment 100 of the vehicle 1. The equipment 54 is fixed below the support 10.

[0047] For example, the length of the support 10 in the transverse direction is 754 mm, the width of the support 10 in the longitudinal direction is 274 mm, and the height of the support 10 is 60 mm.

[0048] An embodiment of a method for assembling or mounting the arrangement 2 will now be described. Initially, a crate 5 is provided, comprising the left side member 3 and the right side member 4. At least one left bracket, preferably the first left bracket 31 and the second left bracket 32, are already attached to the left side member 3. At least one right bracket, preferably the first right bracket 41 and the second left bracket 42, are already attached to the right side member 4. The support 10 for attaching the equipment 51, 52, 53, 54, 55 is also provided. Optionally, all the equipment, or only some of the equipment, is pre-attached to the support 10 and / or under the support.

[0049] Next, a step is performed to position the crate 5 on the support 10. To do this, the crate 5 is translated vertically, from top to bottom, so that the left legs 31, 32 and the right legs 41, 42 come directly above the support 10. In other words, the support 10 is positioned so that the legs 31, 32, 41, 42 of the crate can come precisely into contact with the support 10, above the two transverse ends of the support 10. Then, it only remains to perform a step of tightening the screws 33 to make them cooperate with the nuts 34 of the support 10 on the left side (see [Fig.9]) and a step of tightening the screws 43 to make them cooperate with the nuts 44 of the support 10 on the right side. Note that this screwing is particularly easy since it is done from above and the support is preferably held securely in position. The screws are therefore inserted into the corresponding nuts by The top also allows for excellent visibility during this assembly step. After screwing, the support, possibly previously equipped with some or all of the equipment 51, 52, 53, 54, 55, is then joined to the crate 5.

[0050] Possibly, some or even all of the equipment is fixed after the "bare" support has been fixed to the case 5.

[0051] In summary, the solution relates to a multifunctional support 10 optimized in terms of cost, mass while being compatible with the shock constraints linked in particular to a relatively short overhang D (see [Fig.l]), for example of the order of 75 cm.

[0052] Thus, the arrangement 2 extends only slightly forward along the longitudinal X direction. This characteristic is achieved in particular by optimizing the placement of the equipment, namely sandwiched on either side of the support 10, that is, above and below. Furthermore, the equipment is preferably arranged with its longest dimension extending along the transverse direction so as to limit its footprint in both the longitudinal and vertical directions. This may result in a space remaining below the support, even though it supports equipment 53, 54, 55 below. In other words, the equipped support occupies one floor, and another floor or level remains available below.

[0053] Thus, the architecture and arrangement of the elements are compatible with the low overhang of the vehicle.

[0054] The solution therefore eliminates the need to design, manufacture, and assemble a specific support for each piece of equipment. Significant savings are thus achieved in design time, trials, tests, inventory management (a single support part number instead of five), and manufacturing time. Furthermore, the solution uses less material, making it more economical and, consequently, lighter. In the illustrated embodiment, five pieces of equipment are received, held, and positioned relative to the single support 10. The vehicle thus equipped has its mass optimized, which improves its range, a particularly desirable feature for electric vehicles.

[0055] As a reminder, the accordion-like Omega-shaped cross-section of the support facilitates and optimizes the placement of components or equipment. In particular, the equipment 52, preferably a high-voltage, beltless electric air conditioning compressor, for example, on the order of 800 V, is partially housed in the Omega-shaped recess between the two U-shaped beams 13 and 14 of the support 10, as illustrated in [Fig. 8]. Preferably, the lower part of the compressor 52 is housed in the recess between the two U-shaped beams forming part of the support 10. Advantageously, the arrangement 2 includes a base 20, an intermediate support, between the support 10 and the compressor 52. The base 20 or the compressor 52 then includes a means A filtration unit 21 is arranged between the base and the compressor so as not to transmit vibrations from the compressor to the support, and consequently to the vehicle body 5. For example, this base 20 is made of aluminum alloy, preferably cast. Thus, the compressor 52 is arranged at the front of the vehicle, even if the engine is located at the rear, with the air conditioning system 60 also preferably being arranged at the front of the vehicle.

[0056] Furthermore, the shape of the support 10 offers improved inertia in the vertical direction, which allows for a reduction in the thickness of the sheet metal used to produce the support. As previously mentioned, this results in material savings, and therefore a reduction in material cost and mass. As previously discussed, folds and / or rounded and / or embossed and / or debossed features 16 and / or chamfered edges 17 are preferably provided. These shapes 16, 17 stiffen the support 10 without adding significant material or mass.

[0057] Preferably, as illustrated in Figures 6 and 7, an opening or hole 18 is provided in the substantially flat portion 15 of the support 10 at the level of the receiving area for the equipment 51. Preferably, the equipment 51 is the 12 V battery, for example a lead-acid battery, also known as a service battery, which is generally equipped with a hose or pipe for draining the acids from such a battery. Thus, the hose is inserted into the hole 18 so that it passes through the support 10 and can extend to the bottom of the vehicle in order to prevent any contact between the draining acidic substances and the chassis or a component of the vehicle.

[0058] The shape of the support 10 offers a further advantage in terms of crash or frontal impact behavior C, schematically illustrated in [Fig. 8]. Indeed, the support 10 compresses and bends at its flat portion 15 between the two beam-type portions 13, 14 during a frontal impact. Thus, the support 10 does not interfere with the damping function provided by the side members. It should be noted that the method of attaching the support to the side members helps to avoid interfering with the function of the side members in the event of an impact. In fact, the two left-hand brackets 31, 32, independent of each other and spaced apart along the longitudinal direction, and the two right-hand brackets 41, 42, independent of each other and spaced apart along the longitudinal direction, have little impact on the stiffening of the support.Thus, the flat or substantially flat portion 15 of the support can bend without difficulty thanks to these four spaced, point fixings 31, 32, 41, 42 with the body 5. Preferably, these four tabs are fusible, breaking, or their fixing welds on the side member failing in the event of an impact, in particular the two tabs 31, 41 located at the front of the vehicle. In other words, the support 10 does not interfere with, nor limit, the compression of the side members 3, 4 during an impact. For example, the center-to-center distance between two screws 33, respectively two screws 43, for fixing the support, along the longitudinal direction, is within a range of . from 150 to 200mm, in particular around 190 mm. The flat portion 15 between the two left or right fixing points extends in the longitudinal direction between 80 mm and 130 mm so as to allow easy folding in case of impact.

[0059] Preferably, the element or equipment 54 is preferably known by the abbreviation HVCH, for the English term High Voltage Central Heating. It is an element for heating the fluid in the cooling / heating system of the vehicle, for example by including a heating element.

[0060] Preferably, the component or equipment 55 is known as the "Chiller" and is part of the vehicle's air conditioning system 60. It enables heat exchange between a liquid and a gas used in the air conditioning system, and vice versa. The component 55 is preferably connected by two gas pipes (inlet / outlet) and two liquid pipes (inlet / outlet). Thus, the component 55 allows heat to be transferred from the liquid to the air conditioning gas or cold from the gas to the liquid.

[0061] Preferably, element 53 is a seven-way solenoid valve, for example, forming part of the cooling system. It is capable of distributing coolant to different components depending on the desired cooling modes, for example, cooling a battery, the passenger compartment 100, or an electric motor of the EPT (Electric Power Train), or only the passenger compartment.

[0062] As mentioned previously, the attachment of the components 51, 52 to the support 10 is facilitated by nuts 161, 162, preferably welded under the support, being arranged on the lower face 11. Thus, it is sufficient to insert screws 171, 172 from above, through holes provided in each component (or its base, if applicable), and tighten with the nuts 161, 162. The attachment of the components 53, 54, 55 under the support is also facilitated by screws or studs 173, 174, 175, preferably welded to the support 10, extending substantially vertically under the support 10. Thus, it is sufficient to place each element 53, 54, 55, for example, one by one, through holes provided in these elements so that the rods The threaded ends of screws or studs 173, 174, 175 protrude. Then, simply use nuts to tighten these screws to secure each element to the support.Note that these screws 173, 174, 175 contribute to the pre-holding of the respective components 53, 54, 55 before the nuts are tightened.

[0063] Obviously, other equipment, instead of, or in addition to, or fewer pieces of equipment than those mentioned, may be fixed to or under the support 10. Optionally, the equipment fixed to the support in the illustrated embodiment may be fixed under the support and / or vice versa. In this case, the support may have a different shape, or even be mounted upside down.

[0064] In summary, the solution makes it possible to attach several components, for example five, by means of a single support 10 extending transversely within an engine compartment 7 arranged at the front. As mentioned, the solution reduces the overall mass of the vehicle by requiring only one support, rather than one for each component to be attached. This results in a reduction in the number of fastening systems, particularly screws and / or nuts. Specifically, only two screws 33 and two screws 43 are needed to attach the single support 10 to the body 5. Obviously, the solution reduces the number of supports since only one is required.

[0065] Furthermore, on an electric vehicle with a rear-mounted electric motor, preferably of the rear-wheel drive type, it becomes easy to mount a motor at the front, preferably an electric motor under the support and consequently under the equipment 53, 54, 55, as applicable. Indeed, the solution that allows the equipment to be arranged and concentrated around the support 10 offers available space underneath. In other words, the solution facilitates the transition from a rear-wheel drive vehicle with a rear motor to a four-wheel drive vehicle with a front-mounted drive system, particularly when it involves a relatively compact electric motor.

[0066] Thus, although the engine compartment 7 is cramped, particularly when the front overhang is short, and many bulky components need to be fitted inside, the solution offers space savings. Furthermore, the solution allows several components to be supported on a single support within the engine compartment, while meeting impact regulations, limiting mass, and finally, being particularly economical.

[0067] Although the illustrated embodiment corresponds to a front engine compartment, the solution could be adapted to a rear engine compartment.

[0068] As a note, the solution therefore achieves the objective of housing equipment within a low overhang engine compartment without impacting performance in terms of side member deformation in the event of a collision and has the advantage of being able to be used for other vehicles, for example with a larger front overhang, or even on other vehicles with a small engine compartment.
