Description

Title of the invention: Device intended for fixing a fairing for a vehicle.

[0001] The invention relates to a device for fixing a fairing for a vehicle. The invention also relates to a vehicle comprising at least one such device.

[0002] In a motor vehicle, it appears important to be able to fix a fairing to the vehicle.

[0003] A motor vehicle is known in which the fairing is fixed directly under the body of the vehicle with a rigid metal support.

[0004] However, this solution has drawbacks. In particular, in the event of an impact on the vehicle, such a support can transmit forces to the fixing elements of a battery of the vehicle. This results in a risk of damage to the battery, which can compromise the safety of a user of the vehicle.

[0005] The aim of the invention is to provide a device which overcomes the above drawbacks and improves the known devices of the prior art. In particular, the invention makes it possible to produce a device which has a reduced cost and which allows an improvement in the aerodynamic load and the acoustic level of a vehicle.

[0006] The invention relates to a device intended for fixing a fairing for a vehicle, in particular to a housing of an energy storage element, the device comprising a first part intended for fixing with a fairing of a vehicle and a second part intended for fixing with a housing of an energy storage element, the first part and the second part being mechanically linked together by at least one zone of weakness capable of breaking under the action of a force greater than a predetermined threshold, so as to form a mechanical fuse.

[0007] According to one embodiment, the first part extends along a first plane and the second part extends along a second plane, the first plane and the second plane being in particular perpendicular or substantially perpendicular to each other.

[0008] According to one embodiment, the first part comprises a first opening intended to receive a first fixing means, for example a screw, in particular a threaded screw.

[0009] According to one embodiment, the device comprises a cavity extending from the first opening, in particular perpendicularly or substantially perpendicularly to the first plane, the cavity being configured to receive the first fixing means.

[0010] According to one embodiment, the second part comprises at least a second opening intended to receive a second fixing means, comprising for example a screw and a nut.

[0011] According to one embodiment, the device comprises an anti-rotation system.

[0012] According to one embodiment, said at least one zone of weakness is inclined by report to the first part.

[0013] According to one embodiment, the first part and the second part and the at least one zone of weakness are in the form of a single mechanical part, in particular made of composite plastic, comprising for example glass fibers.

[0014] According to one embodiment, the device comprises an insert, in particular made of at least one metallic material, arranged in the second opening.

[0015] The invention also relates to a vehicle, in particular a motor vehicle, comprising at least one device as defined above, the vehicle comprising a fairing under a housing of an energy storage element, the fairing being fixed by said at least one device to the housing of the energy storage element.

[0034] [Fig. 18] is a diagram representing stress as a function of strain for brittle and ductile materials.

[0035] An electric motor vehicle 200 may include an electrical power system.

[0036] The electrical power system may include a battery 201 mounted under the chassis 202 of the vehicle. The battery 201 may be disposed under the trunk area of ​​the vehicle 200.

[0037] The battery 201 is not covered by any part in the state of the art and is therefore exposed outside the vehicle, under the chassis. The fairing 203 of the vehicle 200 does not cover the lower wall 214 of the battery housing 201 because the fairing 203 does not extend to the rear axle 212 of the vehicle. The lower wall 214 of the battery housing 201 is exposed facing the roadway and close to the ground.

[0038] The housing of the battery 201 may be made of a metallic material, in particular extruded aluminum or a similar material. The battery 201 must be waterproof, so that it comprises elements intended to ensure the waterproofing of the battery, in particular seals 204, a cover 205, welds 206, as shown in [Fig. 2],

[0039] The housing or casing of the battery 201 may comprise longitudinal walls 207, in particular a first longitudinal wall 207a and a second longitudinal wall 207b opposite each other, particularly represented by FIGS. 2 and 3. The first longitudinal wall 207a is called the front face of the battery and is intended to face the rear axle of the vehicle. The second longitudinal wall 207b is called the rear face of the battery.

[0040] Elements sensitive to environmental attacks can be arranged on the first and second longitudinal walls 207a, 207b, in particular a first battery discharge valve 208, of the type commonly designated by the acronym of Anglo-Saxon origin PRD for “Pressure Release Device”, a second battery discharge valve 209, of the Nitto pellet type, as well as high voltage electrical connectors and battery signal 210, of the RCS type. The electrical connectors 210 comprise a locking element to prevent their disconnection without tools. The first battery discharge valve 208 is intended to release the gas in a controlled manner when the pressure inside the battery is greater than a threshold value. The second battery discharge valve 209 contributes to the sealing and breathing of the battery.In the event of a variation in atmospheric pressure, for example a decrease in atmospheric pressure in the mountains, the second battery discharge valve 209 allows balancing with ambient pressure to avoid damaging the battery. All these elements are sensitive for the safety of a vehicle user and must therefore be protected. A failure or non-compliance of these elements directly or indirectly leads to potential risks for the safety of the vehicle user, as well as other risks of non-compliance in the approval file necessary for the sale of the vehicle.

[0041] Environmental aggressions can be gravel aggressions, due to small stones which come from the roadway, aggressions due to a jet of cleaning water, the disconnection of the battery by an external manipulator, for example when the vehicle is suspended from a repair bridge.

[0042] The first battery discharge valve 208 and the second battery discharge valve 209 must therefore be protected because if they do not function correctly, this poses a risk to the safety of a user of the vehicle. The high-voltage electrical connectors 210 must be protected to prevent any unprotected direct access to these connectors, which represent a risk to the safety of a user, and to prevent a user from disconnecting the connectors. The lower wall 214 of the battery housing 201 must be protected to prevent a risk of loss of sealing if the lower wall 214 is deformed and to prevent a risk of corrosion by gravel attack.

[0043] The elements 208, 209, 210 can be protected against environmental aggressions in the following manner. The first battery discharge valve 208 and the second battery discharge valve 209 can be protected with bars 213 welded on the second longitudinal wall 207b of the battery housing 201. The bars 213 are intended to protect the first battery discharge valve 208 and the second battery discharge valve 209 with respect to a water jet. The high voltage electrical connectors and battery signal 210 can be protected by an internal locking element called 'interlock', usually used to protect such high voltage connectors. The bottom wall 214 of the battery housing 201 may be protected by a special cataphoresis coating impregnated onto the metallic material. The bottom wall 214 of the battery housing 201 closes the battery housing at the bottom and is intended to protect the electronic elements inside the housing.

[0044] The applicant sought to improve the aforementioned protective elements by another solution, in particular with a view to reducing costs. The solution according to the concept of the invention is to extend the fairing of the vehicle so as to completely cover the battery. It is sought to fix the fairing on the side of the front face of the battery, where there is usually no fixing.

[0045] In a motor vehicle, the fairing 203 is usually attached to the vehicle 200 with a metal bracket 215, as shown in Figures 6, 7 and 9, which is welded to the body or structure 216 of the vehicle. A welded nut 217 is arranged on the free end of the bracket 215. The nut 217 makes it possible to attach the fairing 203 via a plastic clip 218 which is inserted directly onto this nut 217.

[0046] In the location area of ​​the battery 201 in a vehicle 200, more precisely at the front of the battery 201, at a location close to the rear axle 212, there are architectural elements which prevent the fairing 203 from being fixed directly to the structure 216 of the vehicle 200, in a vertical direction in which the support 215 extends, such as a cup of the rear axle spring 219, battery supports 220, the high-voltage electrical connectors 210, the rear axle 212, the ground clearance or distance to the roadway, mounting elements in the assembly line. It is therefore not possible for the fairing 203 to be fixed to the front of the battery 201 via a support directly to the chassis of the floor 222 of the vehicle. The only available area is indicated with reference 221 in [Fig.9] and this area is not sufficient for efficient fixing.

[0047] The attachment of the fairing 203 to the front of the battery 201, and with determined distances between its attachments, is required by design constraints thereof. The fairing 203 is preferably attached on the side of the front face of the battery 201. One solution would be the attachment of the fairing 203 directly to the housing of the battery 201. Such an attachment of the fairing 203, that is to say directly to the battery 201 and in a rigid manner, for example with a metal part, would involve several risks for the operation thereof.

[0048] Indeed, if such a fixing were arranged in the lower wall 214 of the housing of the battery 201, this would result in possible plastic deformations of the lower wall 214 of the housing of the battery 201 in the event of an impact or considerable stresses, which would compromise the various sealing interfaces. This could result in a problem of operation of the battery 201 and a risk for a user. vehicle's display. A leak in the 201 battery would lead to a risk of uncontrolled leakage of harmful gases to the outside of the vehicle in the event of an incident. Moisture, water, or even dust could enter the 201 battery case.

[0049] If the fairing 203 were fixed directly to the battery housing 201 in a rigid manner, in the event of an impact, the forces would be transmitted directly through welds 223 of the supports 220 of the battery 201 to the structure 216 of the vehicle (battery support part 224 and reinforcement 225 of the floor 222 of the vehicle). These welds are also considered as sensitive elements for the safety of a user, because they participate in the absorption of forces in impact situations on the vehicle. Consequently, a rigid attachment between the fairing 203 and the battery housing 201 is not recommended.

[0050] It is therefore an object of the invention to propose a solution for fixing a motor vehicle fairing, which avoids the risks linked to the solutions mentioned above and which allows an overall reduction in costs, while achieving maximum protection of a component to be protected, in particular a battery.

[0051] The applicant sought to remove certain protective elements for sensitive parts of a battery for a vehicle and to provide protection for the entire battery by extending the vehicle fairing, which usually does not cover the entire battery.

[0052] To this end, the invention proposes a device for fixing a fairing for a vehicle forming a mechanical fuse. In the event of mechanical stresses considered to be "extreme", which only occur in the event of a major impact of the fairing against elements external to the vehicle (kerbs, blunt objects on the road such as stones, etc.), the device breaks. An advantage of such a device lies in the fact that the energy from a violent impact on the fairing is not transmitted to the battery and its fixings, but is used to slightly deform and break the device. Consequently, since there is no propagation of energy to the welds of the battery, the risk of breakage of these welds and of the fixings of the battery to the vehicle is eliminated. This results in increased safety for a user of the vehicle.

[0053] An embodiment of a device 1 intended for fixing a fairing 103 for a vehicle 100, in particular to a housing of an energy storage element 105, is described below with reference to FIGS. 10 to 16.

[0054] The vehicle 100 may be a motor vehicle. The vehicle 100 is, for example, a vehicle with an electric or hybrid motor.

[0055] The fairing 103 may be made of plastic, possibly reinforced with glass fibers.

[0056] The device 1 comprises a first part 3 and a second part 5.

[0057] The first part 3 is intended for attachment to a fairing 103 of a vehicle 100.

[0058] The second part 5 is intended for attachment to a housing of an energy storage element 105, in particular a battery. The energy storage element 105 may be attached to the body of the vehicle, in particular to the chassis, for example to at least one cross member and / or to at least one side member.

[0059] The first part 3 and the second part 5 are mechanically linked together by at least one weak zone 7 capable of breaking under the action of a force greater than a predetermined threshold, so as to form a mechanical fuse.

[0060] The device 1, in particular the first and second parts 3, 5 and the at least one weak zone 7 may be in the form of a single, monobloc mechanical part. They may in particular be made of at least one composite plastic material, comprising for example glass fibers, for example a maximum of 30% glass fibers. Such glass fibers make it possible to confer a certain weakness to the material of the device 1 while increasing the hardness of the material. The device 1 must be sufficiently strong to be able to fix the fairing 103 to a housing of an energy storage element 105, but fusible so that it is this device which is damaged in the event of an impact and not the fixings or welds of the energy storage element to the rest of the vehicle.

[0061] The device 1 is for example formed by injection of at least one plastic material. The percentage of glass fibers may be chosen so as to be compatible with formation of the device 1 by injection of at least one plastic material. Mechanical simulations may be carried out to determine an optimum percentage of glass fibers.

[0062] The device 1 may comprise two weak zones 7 on both sides of the device.

[0063] The thickness e of the weak zone 7 will be chosen so that the weak zone is capable of breaking under the action of a force greater than a predetermined threshold. By thickness e of the weak zone 7 is meant the dimension of the weak zone 7 in the Y direction, according to the reference represented in [Fig. 10].

[0064] The rupture of the device 1 means that it has exceeded the maximum breaking stress of the material and that a fracture occurs in the material, so that the device 1 is separated into two parts 3, 5. The maximum breaking stress of the material is therefore the melting point of the device 1, the maximum stress that the device 1 can withstand (breaking threshold). The device 1 is dimensioned in such a way that it never reaches this point, except during a large impact.

[0065] The device 1 may comprise at least one fragile plastic material. This means, according to the diagram in [Fig. 18], that for a brittle material (curve 301), for a low deformation, the material quickly reaches the value Fl, which represents the breaking limit of device 1. On the contrary, for a ductile material (curve 302), it takes considerably more deformation of device 1 or of the material to reach the breaking value F2.

[0066] For a device 1 intended for fixing a fairing 103 for a vehicle, it is necessary that, as a result of a sudden impact, the device 1 can break and not propagate the forces towards the energy storage element 105. The area under each curve represents the deformation energy that the material is capable of absorbing. The higher the absorbed energy, the higher the energy transmitted through the housing of the energy storage element 105. The elastic and plastic deformation of the device 1 are minimal. All the force is used to fracture the device 1 (brittle material) and not to expand it (ductile material).

[0067] The first part 3 of the device 1 can extend along a first plane (X, Y).

[0068] The first part 3 may comprise a flat face 4 extending along the first plane (X, Y). The face 4 of the first part 3 is intended to be in direct contact with the fairing 103.

[0069] The second part 5 of the device 1 can extend along a second plane (Y, Z).

[0070] The second part 5 may comprise a flat face 6 extending along the second plane (Y, Z). The face 6 of the second part 5 is intended to be in contact with the housing of an energy storage element 105.

[0071] The device 1, in particular the second part, will be configured according to the geometry of the energy storage element 105.

[0072] The first plane (X, Y) and the second plane (Y, Z) are in particular perpendicular or substantially perpendicular to each other depending on the embodiment.

[0073] The device 1 has for example an 'L' shape, considering a section through a plane parallel to the plane (X, Z).

[0074] The at least one weak zone 7 has a mechanical fuse function. It is through this zone that the device 1 will break during a strong impact.

[0075] The at least one weak zone 7 may be a lighter zone made of plastic material than the first part 3 and the second part 5. The at least one so-called weak zone 7 is thus less reinforced than the rest of the device 1. Nevertheless, the at least one so-called weak zone 7 must withstand the usual forces. For this, drawing instructions will be followed.

[0076] The at least one weak zone 7 may be a more fragile portion of the lower section of the device 1. An optimum section will be chosen for the at least one weak zone 7, in particular so as to satisfy a compromise so that the device 1 breaks during an impact but is sufficiently resistant throughout the entire service life. of the vehicle (taking into account the fairing 103, assembly forces, vibration forces).

[0077] Said at least one zone of weakness 7 may be inclined relative to the first part 3, in particular relative to the first plane (X, Y). This allows the device 1 to resist shock forces in any direction despite the main direction of the shock forces being the vertical direction Z.

[0078] The dimensions of the device 1 may be minimized to comply with the architectural and mounting constraints of the device 1.

[0079] The dimension of the device 1 in the X direction is called length L. The dimension of the device 1 in the Y direction is called width W. The dimension of the device 1 in the Z direction is called height H.

[0080] The length L of the device 1 is for example of the order of 22 mm. The width W of the device 1 is for example of the order of 40 mm. The height H of the device 1 is for example of the order of 40 mm.

[0081] The first part 3 may comprise a first opening 13 intended to receive a first fixing means 23, for example a screw, in particular a threaded screw.

[0082] The first opening 13 has dimensions configured to accommodate a self-tapping screw 23, along the Z axis.

[0083] The device 1 may comprise a cavity 14 extending from the first opening 13, in particular perpendicularly or substantially perpendicularly to the first plane (X, Y), the cavity 14 being configured to receive the first fixing means 23.

[0084] The head of the first fixing means 23 must remain above the ground clearance 132, which is a limit not to be exceeded by all the mechanical elements except the fairing 103.

[0085] The cavity 14 may have dimensions determined to be able to accommodate the first fixing means 23.

[0086] Advantageously, the cavity 14 is closed at its end opposite the opening 13. This makes it possible to avoid the accumulation of water in the lower part of the vehicle, in particular when cleaning the vehicle, for example with a water jet.

[0087] According to a variant, the first fixing means 23 may be a type of fixing other than a self-tapping screw. The first fixing means 23 may be chosen according to the constraints and needs (assembly requirements, sealing, reduction of the diversity of the fixing parts, etc.).

[0088] The second part 5 may comprise at least one second opening 15 intended to receive at least one second fixing means 25, comprising for example a screw 26, in particular threaded, and a nut 27.

[0089] The positioning of the device 1 can be carried out via the second opening 15.

[0090] The device 1 may comprise at least one insert 16, in particular made of at least one metallic material, arranged in the second opening 15.

[0091] The at least one insert 16 is for example made of steel.

[0092] The second part 5 may comprise several openings. The device 1 may comprise several inserts.

[0093] The at least one insert 16 is intended to avoid damaging the device 1 along the X axis when the at least one second fixing means 25 is inserted into the at least one second opening 15. The at least one insert 16 is intended to avoid damaging the device 1 with the fixing screw 26 on the housing of an energy storage element 105.

[0094] The second part 5 may comprise a hollowed-out part 18. The hollowed-out part 18 is for example located in the center of the second part 5 in the direction Y. This results in a reduced mass of the device 1.

[0095] The device 1 may comprise an anti-rotation system 9. The anti-rotation system 9 may comprise an extension or tab, in particular made of plastic, intended to be in contact with the lower wall 114 of the housing of the energy storage element 105 and to prevent rotation of the device 1 when it is fixed with the housing of the energy storage element 105. The anti-rotation system 9 is intended to prevent rotation of the device 1 during assembly for mounting the device 1, in particular by tightening in the clockwise direction. The anti-rotation system 9 is intended to pre-hold the device 1.

[0096] The device 1 may be configured so as to comply with the following mechanical constraints. The device 1 is capable of withstanding the usual operating forces, without reaching the breaking state. These forces may be the following. The device 1 is capable of withstanding the forces of water fording. The device 1 is capable of withstanding a point force less than a threshold force value in the vertical direction Z, which is applied over the entire surface of the fairing 103 of the vehicle 100. The device 1 is capable of withstanding aerodynamic forces. The device 1 is capable of withstanding a continuous force in the vertical direction Z, which is applied over the entire surface of the fairing 103 of the vehicle 100. The device 1 is capable of withstanding forces linked to the vibration of the vehicle. The first natural frequency mode must be greater than a threshold frequency value.The device 1 is capable of withstanding the forces associated with the assembly and disassembly of the fairing 103 on the housing of the energy storage element 105. The device 1 must break under an impact force.

[0097] The invention also relates to a vehicle 100, in particular a motor vehicle, comprising at least one device 1 of the type described above, the vehicle 100 comprising a fairing 103 under a housing 105 of an energy storage element, the fairing 103 being fixed by said at least one device 1 to the housing 105 of the element energy storage.

[0098] The fairing 103 is for example fixed to the housing 105 of the energy storage element by two devices 1.

[0099] According to a variant, the at least one weak zone 7 may be arranged at another location of the device 1.

[0100] An advantage of a device 1 of the type described above lies in a reduction in the cost of protecting an energy storage element. The battery discharge valves are protected by the fairing 103. The high voltage electrical and battery signal connectors are protected by the fairing 103. The lower wall 114 of the battery housing 201 is protected by the fairing 103. This makes it possible to eliminate the cost associated with cataphoresis of the lower wall 114 of the battery housing 201 usually carried out against gravel attacks.

[0101] An advantage of a device 1 of the type described above is linked to the fact that it makes it possible to reduce the repair costs of the energy storage element in the event of a collision, since it avoids having to repair or completely replace the energy storage element.

[0102] An advantage of a device 1 of the type described above is linked to the fact that it has a reduced manufacturing cost, since it is formed by injection of at least one plastic material and has reduced dimensions.

[0103] An advantage of a device 1 of the type described above is linked to the fact that its possible replacement by another device 1 results in a reduced cost.

[0104] An advantage of a device 1 of the type described above lies in the fact that its attachment to a housing of an energy storage element is quick to implement.

[0105] An advantage of a device 1 of the type described above is linked to the fact that it makes it possible to improve the aerodynamic load and the acoustic level of the vehicle because the fairing can cover the entire energy storage element.

[0106] Although the invention has been described in the case of a device intended for fixing a fairing for a vehicle, in particular to a housing of an energy storage element, such a device may be used to fix any part to another part in the case where a limit of transmission of forces on the part which holds the other part must be respected.

[0107] Although the invention has been described in the case of a device intended for fixing a fairing for a vehicle, in particular to a battery housing, such a device could be used to fix a fairing to an energy storage element other than a battery, for example in the field of aeronautics.
