Description

Title of the invention: Arrangement comprising a means of protecting a battery during a pole impact. Technical field of the invention

[0001] The invention relates to an arrangement for a vehicle comprising an element to be protected, a chassis, and a means of protecting the element. The invention further relates to a vehicle comprising such an arrangement. Prior art

[0002] An electric or hybrid vehicle, in particular a motor vehicle, generally includes a traction and / or propulsion battery extending along the floor of such a vehicle. Generally, the battery has a substantially parallelepiped shape, the thickness of such a battery extending in the vertical direction being much less than the length extending in the longitudinal direction and the width extending in the transverse direction.

[0003] Furthermore, such a battery is generally arranged within a housing, also called an enclosure. Such a housing generally comprises a frame extending substantially vertically around such a battery. Such a housing further comprises internal cross members intended to compartmentalize such a housing, particularly for the purpose of providing mechanical strength to such a housing. Such cross members extend along the transverse direction of such a vehicle.

[0004] Such a vehicle must comply with mechanical resistance regulations against different types of impacts. Among them, a side impact against a pole, commonly called a "pole impact", aims to translate the vehicle laterally against a fixed pole so as to simulate a lateral slide of such a vehicle against a fixed obstacle during a road accident.

[0005] However, in the case of a commercial vehicle, the mass of such a vehicle is very high, for example, on the order of 2800 kg. This results in significant kinetic energy, causing substantial deformation of the vehicle's floor upon impact with a pole. Such deformation leads to damage to the battery casing and, consequently, to damage to the battery itself. It is essential to avoid any damage, breakage, or deformation of the battery. Indeed, such modifications to the battery, even minor ones, can lead to thermal runaway and / or fire.

[0006] Furthermore, a traction and / or propulsion battery equipping such a utility vehicle extends over a very large width in the transverse direction. Optionally, running boards equipping such a chassis at floor level may obstruct the installation of such a battery along the transverse and vertical directions. Presentation of the invention

[0007] The object of the invention is to provide an arrangement remedying the above drawbacks. In particular, the invention proposes an arrangement making it possible to satisfy a regulation related to a "pole impact" compatible with a housing receiving such a traction and / or propulsion battery comprising only a few internal cross members, i.e. a housing offering low transverse rigidity. Summary of the invention

[0008] To achieve this objective, the invention relates to an arrangement for a vehicle, in particular for an electric vehicle, comprising: - an element to be protected, in particular a traction and / or propulsion battery of such a vehicle, the element being parallelepiped or substantially parallelepiped and extending along the longitudinal, transverse and vertical directions, the dimension along the vertical direction being smaller than the other two dimensions of the element, - a chassis for such a vehicle, - a means of protecting the component, particularly against side impacts sustained by such a vehicle, the means of protection being arranged at least partially between the chassis and the element in the vertical direction.

[0009] The protective means may include a panel whose thickness in the vertical direction may be significantly less than the length in the longitudinal direction and the width in the transverse direction.

[0010] The panel may include transverse tubes, in particular tubes with a rectangular cross-section.

[0011] The panel may include a top plate, in particular a sheet metal, arranged above the transverse tubes, the top plate being able to extend in a transverse and longitudinal plane, or substantially in a transverse and longitudinal plane.

[0012] The panel may include a lower plate, in particular a sheet metal, arranged below the transverse tubes, the lower plate being able to extend in a transverse and longitudinal plane, or substantially in a transverse and longitudinal plane.

[0013] The panel may include a first U extending longitudinally to the right and a second U extending longitudinally to the left, the first and second U being able to enclose the lower and upper plates within the U, in particular by sandwiching the transverse tubes between the lower and upper plates.

[0014] The frame may include a right-hand tubular drip edge extending longitudinally and a left-hand tubular drip edge extending longitudinally, the right and left drip edges being able to be arranged in the vertical direction opposite the panel and / or of the element and on either side of the panel according to the transverse direction.

[0015] The protection means may include a right reinforcement arranged within the right tubular flap and a left reinforcement arranged within the left tubular flap.

[0016] Each reinforcement may include a profile filling at least partially the volume of each flap, particularly opposite the element to be protected in the vertical and longitudinal directions.

[0017] The element can be fixed by means of protection, in particular to the panel.

[0018] The panel can be a welded mechanical structure.

[0019] The invention further relates to a vehicle, in particular a motor vehicle, comprising an arrangement as defined above. Presentation of the figures

[0020] These objects, features and advantages of the present invention will be described in detail in the following description of an embodiment of an arrangement, given by way of non-limiting example, in relation to the accompanying figures, among which:

[0026] 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.

[0027] As illustrated in [Fig. 1], a vehicle 1, in particular a motor vehicle, comprises an arrangement 2. The vehicle 1, or the arrangement 2, comprises an element 3. Preferably, vehicle 1 is electric or hybrid, and component 3 is a traction and / or propulsion battery used to power vehicle 1. Alternatively, component 3 is a fuel cell or part of a fuel cell, or another type of component requiring protection, particularly in the event of a side impact. The component 3 to be protected is parallelepiped-shaped, or substantially parallelepiped-shaped. The component 3 extends along the longitudinal, transverse, and vertical directions of the vehicle, and its dimension value along the vertical direction is smaller than its dimension values ​​along the transverse and longitudinal directions.

[0028] Preferably, the vehicle 1 is a utility vehicle, in particular a van.

[0029] More specifically, as illustrated in particular in Figures 3 and 4, the arrangement 2 comprises the element 3 to be protected. The illustrated embodiment relates to an element 3 of the traction and / or propulsion battery type for the vehicle 1. The battery 3, or modules of the battery 3, are housed and arranged within a casing 30 illustrated in Figures 2, 3, 4, and 5. The casing 30 comprises a frame 33, preferably rectangular or square in shape. The casing 30 further comprises cross members 31, for example, at least two cross members 31, intended to extend transversely with respect to the vehicle 1 (see Figures 2 and 5).

[0030] Optionally, arrangement 2 includes housing 30.

[0031] The arrangement 2 further comprises a chassis 4 for the vehicle 1. Preferably, as illustrated in [Fig. 2], the chassis 4 comprises a body side 6 on each side (one body side arranged on the right and one body side arranged on the left). For example, each body side 6 is an independent structure that is assembled to the rest of the chassis 4. Alternatively, the vehicle comprises a self-supporting body, i.e., an assembly comprising the chassis and the two body sides.

[0032] Arrangement 2 further includes a means of protecting battery 3 10. As will be seen later, the protection means 10 aims to preserve the integrity of the battery in the event of a side impact, particularly during a simulated vehicle slide called a pole impact intended to satisfy a regulation.

[0033] More specifically, as illustrated in the exploded view of [Fig. 2], the protection means 10 is arranged, at least partially, between the chassis 4 and the battery in the vertical direction, the battery being housed within the casing 30. Preferably, the protection means 10 extends in a transverse and longitudinal plane, or substantially in such a plane, between the battery (not shown in [Fig. 2]) housed in its casing 30 and the chassis 4. In other words, the protection means 10 is sandwiched between the chassis and the battery, at least between the chassis 4 and the casing 30 of the battery 3.

[0034] Preferably, the protective means 10 comprises a panel, plate, or tray 20. The thickness E20 of the panel 20 in the vertical direction is significantly less to the length L20 of panel 20 along the longitudinal direction of the vehicle and to the width 120 of panel 20 along the transverse direction of the vehicle (see figures 3 and 5). By "significantly less", it is meant that the thickness E20 of panel 20 is, for example, less than 30 times the length L20 of panel 20 or the width 120 of the panel, or that the thickness E20 of panel 20 is, for example, less than 5 cm, for example, on the order of 3.5 cm, while the length L20 of panel 20 is, for example, on the order of 2 m and the width 120 of the panel is, for example, on the order of 1.5 m.

[0035] As illustrated in Figures 2 and 5, the panel 20 comprises transverse tubes 21. The transverse tubes extend transversely, that is, along the transverse direction of the vehicle 1. Preferably, the transverse tubes 21 have a rectangular cross-section. For example, ten to fifteen transverse tubes 21 are arranged within the panel 20. By way of example, the width of each tube, along the longitudinal direction of the vehicle, is 5 cm, with a height of 3.3 cm and a tube thickness of 1 to 1.5 mm. Preferably, each transverse tube 21 is made of steel, in particular ultra-high-strength steel. Even more preferably, the transverse tubes 21 are spaced 4 cm to 8 cm apart along the longitudinal direction. Alternatively, the cross-section of some or all of the tubes is square or has another cross-sectional shape.

[0036] Preferably, as illustrated in Figures 2, 3, and 4, the panel 20 comprises a top plate 24. The top plate 24 is arranged above the transverse tubes 21, preferably in contact with the transverse tubes 21. Thus, the top plate 24 extends in a transverse and longitudinal plane, or substantially in a transverse and longitudinal plane. Preferably, the top plate 24 is a sheet, in particular a sheet of Very High Yield Strength steel. For example, the thickness of the top plate 24 is between 1 mm and 1.2 mm.

[0037] Preferably, as illustrated in Figures 2, 3, and 4, the panel 20 comprises a lower plate 22. The lower plate 22 is arranged below the transverse tubes 21, preferably in contact with the transverse tubes 21. Thus, the lower plate 22 extends in a transverse and longitudinal plane, or substantially in a transverse and longitudinal plane. Preferably, the lower plate 22 is a sheet, in particular a sheet of Very High Yield Strength steel. For example, the thickness of the lower plate 22 is between 1 mm and 1.2 mm.

[0038] Preferably, each plate 22, 24 is attached to the transverse tubes 21 by welding, in particular by arc welding using dashes or beads, for example at least five beads approximately 20 mm long on at least two edges of each tube 21, or even on all four edges of the tubes. In this case, the beads joining the second plate to the tubes are, for example, made from the outside, by example via openings, particularly oblong ones, made in the second plate vertically above the tubes with which the second plate is welded.

[0039] Advantageously, as illustrated in Figures 2 and 3, the panel 20 comprises a first U 25 extending longitudinally to the right and a second U 26 extending longitudinally to the left. The first and second U 25, 26 enclose, surround, and house the lower and upper plates 22, 24. Thus, the hollows of each U are opposite each other, the Us each lying on one of their bars. Preferably, the Us sandwich the ends of the transverse tubes 21 as well as the lower and upper plates 22, 24. For example, each U is of the profiled type, obtained by hot or cold forming. Alternatively, each U is obtained by two folds of the same rectangular sheet. Preferably, each U is made of sheet metal, in particular steel, for example high-yield-strength steel, for example having a thickness between 1.5 mm and 2.5 mm.

[0040] Preferably, each U is fixed to the plates 22, 24 by welding, in particular by arc welding using dashes or beads, for example beads approximately 20 mm long and at least ten in number. For example, the beads are made between the ends of the U, at the edges, and each plate 22, 24.

[0041] Thus, preferably, the panel 20 is a welded mechanical structure.

[0042] As illustrated in particular in Figures 3 and 4, the chassis 4 and / or the body side 6 comprises at least one tubular right-hand drip edge (not shown), typically rectangular in cross-section, extending longitudinally, and at least one tubular left-hand drip edge 7G extending longitudinally. For example, the drip edges are arranged within the chassis and / or within each body side. The tubular right and left-hand drip edges extend, for example, vertically opposite panel 20 and / or battery 3 and transversely on either side of panel 20. For example, each drip edge has a square or rectangular cross-section along a vertical and transverse plane. Each drip edge is preferably a hollow body extending longitudinally.

[0043] As illustrated in particular in Figures 3 and 4, the protective means 10 further comprises a left-hand reinforcement 12 arranged, housed, and fixed inside the left-hand tubular drip edge 7G, and a right-hand reinforcement arranged within the right-hand tubular drip edge (not shown). Preferably, each reinforcement comprises, or is of the profile type, filling at least partially the volume of each corresponding drip edge. Thus, preferably, each drip edge includes an empty volume, with each reinforcement preferably located only in the upper part of each drip edge. For example, each profile is a bar with a square or rectangular external cross-section, compartmentalized by walls, in particular walls perpendicular to each other. For example, the profiles of the reinforcements are made of sheet metal, in particular ultra-high-yield-strength sheet metal. The thickness of the cross-section and walls of each reinforcement is, for example, between 2 mm and 2.6 mm. For example, as illustrated in [Fig. 3], the left-hand reinforcement comprises two vertical walls 13 and two horizontal walls 14. For example, the reinforcements are opposite, facing battery 3 in the vertical direction (case not shown), or offset below battery 3 (case not shown). Preferably, the reinforcements are offset above the battery (case shown in Figures 3 and 4). For example, each profile-type reinforcement is attached to the corresponding chamfer by arc welding, spot welding, or any other type of welding, in particular by means of fixing brackets or angle brackets. Preferably, a step 5 extending substantially longitudinally is arranged on the left, for example, substantially above a chassis chamfer and / or a body side chamfer, i.e., a superstructure chamfer.A step on the right is preferably also provided. For example, the space available to house the panel in the vertical direction under the steps, i.e. between the top surface of the housing 30 and the underside of the steps 5, is approximately 35 mm.

[0044] Preferably, as illustrated in [Fig. 5], the battery 3, or advantageously its housing 30, is secured by means of a protective device 10. More specifically, the housing 30 is attached to the panel 20. For example, screws 32, arranged in rows, pass through the panel 20, or optionally through a cover of the battery housing, to be screwed into the cross members 31 of the housing. Thus, each row of screws 32 is opposite each cross member 31. Alternatively, the screws 32 cooperate with nuts under the housing, or even are arranged in each cross member of the housing, optionally having been previously welded to each cross member 31. For example, four cross members 31 are provided in the housing, and three screws per cross member 31 are provided to ensure assembly.

[0045] Preferably, the arrangement 2, or at least the means of protection 10, has symmetry with respect to a vertical and longitudinal median plane of the vehicle 1.

[0046] In summary, the solution involves adding a protective element, in particular an additional panel-type structure 20 extending primarily in the transverse and longitudinal directions between the chassis 4 and the battery 3. As previously mentioned, the protective element preferably includes further reinforcements extending from the panel in the transverse direction, these reinforcements extending within the side bumpers. The protective element ensures the protection of the battery in the event of an impact against a post P, despite the stresses of a utility vehicle (see [Fig. 4]). Indeed, the solution reinforces the chassis, particularly in the transverse direction, so as to protect the battery housing and, ultimately, the battery itself.Thus, despite the vehicle's considerable mass generating significant kinetic energy, particularly for utility vehicles (for example, on the order of 2800 kg or more), the battery is protected, especially in the lateral direction. Good. Since the battery extends across almost the entire width of the chassis, the protective device reinforces the casing, particularly against pole impacts, i.e., lateral impacts. Thus, even if the battery casing or enclosure is potentially weak, for example, non-structural, particularly with only a few cross members extending along the vehicle's transverse direction (e.g., between two and four cross members), panel 20 and / or the reinforcements in the side skirts create a pathway for lateral forces to pass through. Finally, although the running boards prevent the chassis rigidity from being fully utilized, especially from the floor to its lateral ends, particularly by reducing the available space above the battery, the protective device compensates for, and even increases, this rigidity and protects the battery from impacts, especially those resulting from a pole impact test.As seen previously, the structural plate or panel 20 covers battery 3 and the chassis flanges are filled at least partially by particularly rigid profile-type reinforcements.

[0047] In a lateral impact, the first level or stage of deformation, damping, and energy absorption is preferably based on the reinforcements housed in the right and left side panels. The second level or stage of deformation, damping, and energy absorption is preferably based on the transverse tubes 21 of the panel, possibly supplemented by the U-shaped members and / or the lower and upper plates 22, 24, which contribute to the rigidity along the transverse direction of the panel.

[0048] Thus, the structural panel 20, positioned under the chassis and covering the battery 3 and at least part of the side fenders, fits within the available height, for example, approximately 35 mm. Preferably, the reinforcements arranged within the fenders have a similar or even identical height in the vertical direction to the height E20 of the panel. This arrangement provides very high rigidity at the edge of the vehicle and therefore offers maximum resistance to the post from the outset of the impact. Furthermore, given that the protective means extends along the entire length of the battery, the same level of resistance is achieved regardless of where the impact occurs along the battery.

[0049] Preferably, the panel 20 extended laterally on each side (right and left) by the profiled reinforcements is as wide in the transverse direction as the platform or floor of the vehicle.

[0050] The solution is therefore independent of the floor; it relates in particular to an addition, a structure inserted vertically between the battery and the chassis floor. Thus, the stress paths from a lateral impact pass over the battery, specifically through the reinforcements arranged in the side skirts and / or in the panel positioned above the battery.

[0051] Note that the solution is particularly suitable for an independent chassis, That is to say, the superstructure, including the body sides, is screwed vertically to the chassis. In this case, for example, the superstructure is placed and screwed onto the chassis, for instance, using underbody brackets that preferably extend lengthwise. The protective element, particularly the panel, is positioned under the chassis, specifically between the battery (or more precisely, its casing, if applicable) and the chassis. This solution is also compatible with a self-supporting body.

[0052] The solution meets mechanical resistance regulations against various types of impacts, particularly lateral impacts against poles. Furthermore, the solution offers exceptionally low indentation at the battery casing during a pole impact, i.e., well below the level of indentation permitted by regulations and / or equivalent to that allowed by regulations but at speeds exceeding those of the regulatory test.

[0053] The solution prevents damage to the battery housing, or at least limits it to minimal levels. Deformation, damage, or breakage of the battery is thus prevented, and any thermal runaway of the battery and / or resulting fire are avoided.

[0054] Preferably, the reinforcements are at the same level as the panel 20 in the vertical direction, that is, in line with it in the transverse direction, as illustrated in [Fig. 4]. Thus, the remaining empty volume of the flap(s), i.e., free of profiled reinforcement, is opposite the battery, at the same level in the vertical direction. As a result, the housing 30, and consequently the battery 3, are not at risk of receiving material that deforms towards them, as the flaps would then tend to collapse in their hollow part at the level of the module(s) composing the battery.

[0055] Advantageously, the assembly comprising the panel 20 and the reinforcements within the drip edges is extended as far as possible in the transverse direction so as to maximize resistance to post intrusion, and this as early as possible during the impact. Due to its profiled cross-section as described previously, each drip edge reinforcement is stiff and rigid in terms of bending in order to propagate the impact forces over the greatest possible length in the longitudinal direction. It should be noted that the panel structure, particularly thanks to its cross members 21, is especially rigid in the transverse direction. Preferably, the housing 30 is securely attached to the panel 20 as described previously. Such attachment contributes to the deceleration of the housing containing the battery.

[0056] The solution allows lateral forces from a pole impact to be passed elsewhere than through the frame of the housing 30 and through a floor of the housing 30 receiving the battery 3.

[0057] In other words, the consequences of a side impact are not aggravated by the presence of the vehicle's high-voltage traction and / or propulsion battery. The arrangement incorporating the protective means ensures that the battery casing remains intact during a side impact at 35 km / h, along its entire length in the longitudinal direction. The arrangement incorporating the protective means ensures that only minimal cracks occur in the battery casing during an impact at 45 km / h, along its entire length in the longitudinal direction. For example, such cracks are less than 20 mm. The arrangement also prevents any short circuit within the battery cells, which could lead to thermal runaway and / or fire. Furthermore, the arrangement eliminates any risk of electrocution for the occupants and / or emergency responders following a side impact.

[0058] Finally, thanks to this solution, the traction and / or propulsion battery can extend over a large dimension along the transverse direction of the utility vehicle without risk in the event of a side impact. The presence of side steps at the front and / or rear doors does not pose a problem for the battery's installation, as the panel ends and / or the reinforcements of the protective device preferably come under the steps and do not affect the space occupied by the battery and / or its casing.

[0059] Finally, the arrangement is compatible with a particularly restricted space in the vertical direction between the steps 5 and the housing 30, for example on the order of 35 mm. Indeed, the panel 20 has, for example, a maximum thickness E20 of 35 mm.

[0060] The solution does not affect the center of gravity of the vehicle, the battery remaining arranged at a low level in the vertical direction, and in a balanced, or even centered, manner in the longitudinal and transverse directions.

[0061] The solution is compatible with the presence of a sliding side door rail, or even a translation and / or pivoting system for such a side door, possibly motorized.

[0062] As a note, the solution therefore achieves the objective sought of enabling compliance with regulations related to a pole impact for an electric or hybrid utility vehicle, in particular compatible with a housing receiving such a traction and / or propulsion battery comprising only a few internal cross members, i.e. a housing offering low transverse rigidity, and has the advantages of being able to be used on other types of vehicles, namely trucks, buses, buses, agricultural vehicles, lifting equipment and any other machine.
