Description

Title of the invention: Vehicle arrangement comprising a battery receiving tray capable of allowing liquid to drain while preventing water from entering. Technical field of the invention

[0001] The invention relates to an arrangement for a vehicle comprising a battery capable of leaking fluid, the battery being housed in a container comprising a means of draining such fluid while preventing water ingress. The invention further relates to a vehicle comprising such an arrangement. Prior art

[0002] A vehicle, particularly a motor vehicle, generally includes a lead-acid battery. Such a battery is usually located near cables and / or electronic components and / or electrical components such as fuses. It should be noted that such a battery generally contains an electrolyte.

[0003] However, in the event of a malfunction or failure of such a battery, such electrolyte may leak from the battery. It is therefore important to prevent such electrolyte from coming into contact with such cables and / or electronic and / or electrical components located near the battery. Indeed, such a liquid would degrade the insulation of such cables and / or components, which could lead to malfunctions, as the liquid is often highly corrosive. Presentation of the invention

[0004] The object of the invention is to provide an arrangement that overcomes the above drawbacks. In particular, the arrangement allows a battery to be housed within a container that prevents water from entering while allowing the electrolyte to be drained if necessary. Summary of the invention

[0005] To achieve this objective, the invention relates to an arrangement for a vehicle, in particular for a motor vehicle, the arrangement comprising: - a partition extending between a first zone of such a vehicle free from water spray and a second zone of such a vehicle exposed to water spray and / or immersion, - a battery, in particular a lead-acid battery, the battery being liable in the event of failure to cause a leak of a liquid, in particular an electrolyte liquid, - a tray extending at least partially into the second zone by extending under the partition or through the partition, the tray comprising a cavity communicating with the first zone, the battery being housed in the cavity, the tray comprising a bottom extending in a transverse and longitudinal plane or substantially in a transverse and longitudinal plane, the bottom comprising a means of evacuating such liquid leaking from the battery, the means of evacuation preventing the intrusion of water.

[0006] The evacuation means may include a non-return valve capable of allowing liquid to pass through the bottom while preventing water from entering the cavity.

[0007] The arrangement may include a means for retaining a liquid.

[0008] The retention means may include grooves and / or ribs extending in particular vertically at the bottom of the tray so as to create a liquid storage volume under the battery within the tray.

[0009] The retention means may include a receptacle arranged under the tray opposite the evacuation means, the receptacle being intended to collect a liquid that has passed through the evacuation means.

[0010] The receptacle can be attached to the tray.

[0011] The arrangement may include a seal, the seal being able to extend between the receptacle and the tray so as to prevent any leakage of the liquid collected in the receptacle.

[0012] The receptacle may include a means of trapping the liquid, in particular vertically extending ribs, and / or an absorbent material, and / or baffles.

[0013] The receptacle can be made of translucent material, or include a translucent part, so as to allow at least partial visibility within the receptacle.

[0014] The receptacle can be of overall cylindrical shape.

[0015] The receptacle may include a first rotational fastening means and the tray may include a second rotational fastening means, the first fastening means cooperating with the second fastening means to secure the receptacle under the tray.

[0016] The invention further relates to a vehicle, in particular a motor vehicle, comprising an arrangement as defined above. Presentation of the figures

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

[0031] As illustrated in [Fig. 1], a vehicle 1, for example a motor vehicle, is intended to move on the ground 6. The vehicle 1 includes a powertrain 7. Optionally, the powertrain includes at least one electric traction and / or propulsion motor for the vehicle 1. In this case in particular, the vehicle 1 preferably includes a battery 8 for storing electrical energy. The vehicle 1 also includes an arrangement 2. The vehicle 1 preferably includes a trunk 9, for example arranged at the rear of the vehicle, and a passenger compartment 100.

[0032] The arrangement 2 includes a partition 3. For example, the partition 3 is a floor plate, for example, a steel or aluminum alloy plate, or one made of composite material. Preferably, the partition 3 is the floor of the trunk 9, or at least extends to the level of the trunk 9. Alternatively or in addition, the partition 3 extends to the level of the passenger compartment 100 of the vehicle 1. Optionally, the partition 3 extends to the front of the vehicle, particularly in the case of a vehicle with a trunk arranged at the front, the engine compartment then possibly being arranged at the rear.

[0033] Regardless of the position of the partition 3 in the vehicle, preferably the partition 3 extends transversely and longitudinally, or substantially transversely and longitudinally. More precisely, as illustrated in Figures 2 and 3, the partition 3 extends between a first zone ZI of the vehicle and a second zone Z2. In other words, the partition 3 separates the first zone ZI of the vehicle from the second zone Z2.

[0034] The first zone Zl, referred to as the dry zone, is intended to remain dry. Thus, the first zone Zl is free from water spray and water ingress, even when the vehicle is driven or parked through puddles, across a ford, or even during floods that cause the water level to fall just below the floor 3. Therefore, the first zone Zl remains dry as long as the water and / or mud does not exceed the height level H3 between the floor 6 and the partition 3, as illustrated in [Fig. 2]. Preferably, the first zone Zl is the interior area of ​​the vehicle, including the passenger compartment 100 and the trunk 9.

[0035] The second zone Z2, unlike the first zone Z1, is exposed to splashes of water E and / or mud, and / or to immersion in water and / or mud. The second zone Z2, referred to as the wet zone, is an exterior area of ​​the vehicle 1. Preferably, zone Z2 is an area extending under the vehicle, in the underbody.

[0036] The arrangement 2 includes a battery 4. Preferably, the battery 4 comprises a technology including lead and a liquid electrolyte, for example known by the Anglo-Saxon term "flooded". Preferably, it is a battery 4 capable of causing a leakage of a liquid 5 in the event of failure and / or deterioration of the battery 4. The liquid 5 is, for example, a liquid electrolyte, capable of deteriorating, to attack many materials. For example, battery 4 has a voltage across its terminals of 12V or approximately 12V. Battery 4 is used, for example, to start an internal combustion engine in the powertrain 7.

[0037] The arrangement 2 further includes a tray 10. The tray 10, or housing, extends at least partially into the second zone Z2. Preferably, the tray 10 extends entirely under the partition 3, as illustrated in particular in [Fig. 2]. The tray 10 includes a cavity 11 that communicates with the first zone Z1; that is, the cavity 11 is open towards the first zone Z1. Preferably, as illustrated in [Fig. 2], a sealing means 52, for example a gasket, extends between the tray 10 and the partition, or body, or floor so as to prevent any communication between the first zone Z1 and the second zone Z2 at this junction between the tray and the partition. In other words, the seal between the tray 10 and the partition 3 is maintained by means of the gasket 52.

[0038] The battery 4 is housed, positioned, and advantageously secured in the cavity 11. Preferably, the battery 4 does not protrude from the cavity 11 provided in the tray 10, that is to say, the battery 4 does not extend above the partition 3. The tray 10 comprises a base 12 extending in a transverse and longitudinal plane, or substantially in a transverse and longitudinal plane. Preferably, the battery 4 is placed on the base 12, or at least on a portion of the base 12 of the tray 10.

[0039] For example, as illustrated in [Fig.2], the arrangement 2 or the tray 10 includes at least one counter-stud 51 for the shimming, the fixing of the battery 4 in the tray, in particular of a lower part of the battery 4. In addition, for example, the arrangement 2 or the tray 10 includes at least one flange 50 for fixing the battery 4, in particular in the lower part of the battery. Preferably, at least one flange 50 includes an adjustable, screwable part, for example including at least one screw, so as to allow the battery 4 to be locked, in particular by pinching it downwards, i.e. towards the bottom 12 of the tray 10. At least one counter-base 51 and at least one flange 50 are preferably arranged on either side of the battery 4, in contact with the battery, so as to block all degrees of freedom of the battery once at least one flange 50 is tightened, screwed.In other words, the counter-heel 51 is arranged on a side opposite the side facing the flange 50, particularly in the case of a battery of parallelepiped or substantially parallelepiped shape.

[0040] The vehicle 1 or the arrangement 2 further includes fragile elements 53, which are liable to be attacked and damaged in the event of contact with the liquid 5. Such elements 53 are, for example, electrical cables or wires and / or electronic elements and / or electrical elements such as fuses, for example.

[0041] Alternatively, the tray passes through the partition so that part of the tray extends above the partition and the other part of the tray extends below the partition (case not illustrated).

[0042] The base 12 includes a means 20 for draining the liquid 5 that may leak from the battery 4. The drain 20 prevents the intrusion, entry, arrival of water and / or mud into the cavity 11 of the tray 10. In other words, the base 12 remains watertight even though it includes the drain 20. The cavity 11, and consequently the battery 4 as well as the electrical and / or electronic components 53, and at least one flange 50 and at least one counter-base 51 remain dry.

[0043] According to a first embodiment of the arrangement 2 illustrated in [Fig. 2], the drainage means 20 comprises a non-return valve, a valve 21. The valve 21 is then able to allow the liquid 5 to pass through the bottom 12 if necessary, while preventing the entry of any water that may be present in the second zone Z2. Thus, water splashes E cannot pass through the valve 21, are stopped, and cannot penetrate the cavity 11.

[0044] As illustrated in [Fig.3], according to a second embodiment of the arrangement, the arrangement 2 includes a retention means 30. The retention means 30 allows for capturing, collecting, storing the liquid 5 flowing or seeping from the battery 4. Optionally, as illustrated in [Fig.3], this retention means 30 includes grooves 31 and / or ribs 32 at the bottom 12 of the tray 10. For example, the grooves and / or ribs extend vertically or substantially vertically. In any case, the grooved and / or ribbed shapes allow the creation of at least one liquid storage volume V under the battery 4, within the tank 10. In this case, the grooves may be arranged to guide the liquid 4 towards the drainage means 20. Optionally, these grooves and / or ribs are supplemented by a base 12 including, for example, at least one sloping portion to facilitate this guidance towards the drainage means 20.

[0045] In the second embodiment illustrated in [Fig. 3], the retention means 30 further comprises a collection receptacle 40 arranged under the tray 10. The receptacle 40 is positioned opposite the discharge means 20, possibly centered with respect to the discharge means 20. For example, in the case of a cylindrical or substantially cylindrical discharge means having a vertical axis, the receptacle 40 is cylindrical or substantially cylindrical and its axis coincides with, or is substantially coincident with, the axis of the discharge means. In any case, the receptacle 40 is arranged so as to be able to collect any liquid 5 that has passed through the discharge means 20.

[0046] The receptacle 40 is arranged at the outlet of the non-return valve 21 where applicable, for example opposite the valve, possibly centered with respect to the valve.

[0047] Advantageously, the receptacle 40 is fixed to the tray 10. Preferably, the receptacle 40 is fixed under the tray in a removable manner. Advantageously, the receptacle 40 is cylindrical or generally cylindrical in shape and its axis A40, when fixed under the tray 10, extends in the vertical or substantially vertical direction.

[0048] Note that if a receptacle 40 is used, a non-return valve may be omitted, particularly if a seal is provided between the receptacle and the container 10, as will be seen later. In this case, the drainage means 20 may consist of a simple hole.

[0049] As illustrated in Figures 4 and 5, a rotation R in a first direction is sufficient to secure the receptacle 40 to the tray 10. Conversely, for disassembly or unlocking, a rotation in a second direction opposite to the first is sufficient. For this purpose, the receptacle 40 comprises a first rotational fastening means 43, and the tray 10 comprises a second rotational fastening means 13 adapted to cooperate with the first means 43. Preferably, the tray comprises at least two second fastening means 13, and the receptacle 40 comprises at least two first fastening means 43. For example, as illustrated in Figures 4 and 5, the tray 10 comprises four lugs, hooks 13, and the receptacle 40 comprises four radial extensions, projections 43.To fix the receptacle under the tray, simply slide the receptacle 40 upwards, with the radial projections 43 angularly offset from the hooks 13, until it comes into contact with the bottom 12, then rotate it in the first direction R to lock, or wedge, the radial projections 43 between the hooks 13 and the bottom 12 of the tray 10. Obviously, to remove the receptacle 40 if necessary, a rotation of the receptacle 40 in the opposite direction to the first direction detaches the receptacle from the tray 10. Preferably, at least one gripping means 41, for example of the radial extension type, on the periphery of the receptacle 40, for example two, four or more, facilitates the rotation step both for tightening to lock the receptacle under the tray (first direction of rotation R), and for loosening to remove the receptacle if necessary.Indeed, such extensions 41 facilitate handling for turning, pivoting the receptacle, preferably while wearing the protective gloves recommended for disassembly if liquid 5 is suspected in particular.

[0050] Preferably, as illustrated in [Fig. 6], each hook 13 of the tray 10 includes a limit stop 14 to prevent the rotation R of the radial projections 43 of the receptacle 40. Even more preferably, each end of the radial projection 43 includes a lug or bulge or projection 42, and each hook 13 includes a cavity 15 to receive the bulge 42. Thus, the interaction of the bulge 42 with the cavity 15 creates a locking mechanism for the receptacle 40 under the tray 10. Furthermore, this interaction optionally creates a clicking sound indicating to the operator that the receptacle is correctly fixed. Preferably, the end of each radial projection 43 of the receptacle 40 includes a bevel 44, a pointed profile. This bevel 44 facilitates the insertion, the engagement of each corresponding radial projection between the corresponding hook 13 and the base 12. This is especially true when the arrangement 2 includes a seal 33 extending between the receptacle 40 and the tray 10, as illustrated in particular in [Fig. 5]. Indeed, such a seal 33 tends to push the receptacle 40 downwards when the receptacle is pushed upwards before being rotated to fix it. Thus, it is necessary to overcome the crushing of the seal 33 while rotating the receptacle 40 to fix it. In other words, the receptacle 40 is fixed by rotation and compression of the seal 33 against the body of the tray 10. The presence of the bevel 44 on each radial extension 43 therefore facilitates the insertion of the receptacle between the hooks 13 and the bottom 12.The presence of the seal 33 prevents any leakage of the liquid 5 collected in the receptacle 40 outside of this receptacle. Thus, the seal 33 ensures a watertight seal between the receptacle 40 and the battery mounting tray 10 to prevent any leakage of the liquid 5 outside of the receptacle 40.

[0051] According to an alternative mounting of the receptacle 40 illustrated in [Fig. 7], compatible with the second embodiment of the arrangement with or without a non-return valve, the receptacle 40 includes a tapped hole 431 and the container 10 includes a thread 131 formed around the discharge means 20. In this case, the receptacle is fixed around a cylindrical portion of the container 10 comprising the thread 131. Alternatively, the container includes a tapped hole and the receptacle includes a thread. Optionally, in this alternative mounting of the receptacle under the container, no seal is interposed, particularly if a substantial surface 432 of the receptacle 40, or a shoulder, is provided in contact with a face 121 of the bottom 12 of the container 10 extending opposite the floor 6.

[0052] Advantageously, the receptacle 40 includes a means for trapping and storing the liquid 5 46. According to a first variant of the receptacle 40 illustrated in [Fig. 8], compatible with the second embodiment of the arrangement with or without a non-return valve, the receptacle 40 includes ribs, extensions, or projections 47 extending vertically. Preferably, these ribs 47 extend from a base 400 of the receptacle 40 in the transverse direction of the vehicle, or preferably in the longitudinal direction. These ribs optionally create several spaces or volumes for storing the liquid 5.

[0053] According to a second variant of the receptacle 40 illustrated in [Fig.9], compatible with the second embodiment of the arrangement with or without a non-return valve, the trapping means 46 comprises one or more absorbent material(s) 48 arranged in particular at the bottom of the receptacle 40, for example foam and / or another material compatible to be soaked with electrolyte liquid 5, preferably without disintegrating or deteriorating.

[0054] Advantageously, according to a third variant of the receptacle illustrated in [Fig. 10], compatible with the first variant of the receptacle (ribs 47) and compatible with the second embodiment of the arrangement with or without a non-return valve, the receptacle 40 is made of a translucent, transparent material, or at least includes at least a translucent or transparent portion 45. This allows at least partial visibility inside the receptacle 40. Thus, it is possible to determine whether liquid 5 is present or stored, and, if so, to provide suitable gloves and protective equipment before dismantling the receptacle 40.

[0055] According to a fourth variant of the receptacle illustrated in [Fig. 1 1], compatible with the second embodiment of the arrangement preferably without a non-return valve, the receptacle 40 includes at least one baffle 49. By "baffle" is meant an "extension" extending for example from the bottom 400 opposite or substantially opposite the evacuation means 20. Thus, any liquid 5 evacuating from the means 20 is forced to travel a longer path than the direct path between the evacuation means 20 and the bottom 400 of the receptacle, or the top of the level of liquid 5 already present in the receptacle where applicable.

[0056] A variant of the receptacle 40 combining the first and fourth variants is illustrated in [Fig. 12]. Preferably, in this case, the discharge means 20 includes a hole, an opening, for example in place of the check valve. Alternatively, the hole provided is smaller than that required for the installation of a check valve. It should be noted that this simple hole as a discharge means 20 is compatible with all embodiments comprising the receptacle 40. In these cases, preferably, the receptacle 40 is mounted sealed against, below, the bottom 12 of the container 10. Thus, any liquid 5 passing through the hole 20 is collected in the receptacle 40.

[0057] Optionally, in the variant of the receptacle illustrated in [Fig. 12], the base 12 of the container 10 includes at least one baffle 149 extending downwards, i.e., outwards from the cavity 11. The at least one baffle 149 of the container 10 cooperates with the at least one baffle 49 of the receptacle 40. Optionally, the base 400 of the container further includes ribs 47. For example, the receptacle 40 with baffles and / or ribs is clippable under the container 10, and the gasket 33 provides a seal against the base 12.

[0058] In an alternative not shown, the receptacle may be offset, i.e., not centered with respect to the drainage means, and / or not positioned below the battery, particularly if a component, for example, a structural element of the vehicle such as a side member or crossmember, is located directly below the battery tray and prevents the addition of the receptacle. Optionally, in this case, the bottom of the battery tray may be grooved and / or sloped to guide the fluid towards the offset, or eccentric, collection tray, if applicable.

[0059] In summary, the solution relates to a battery installation tray comprising a means of draining the electrolyte generated by the battery in the event of damage, failure, or extreme malfunction of the battery. Indeed, in this case, it is necessary to drain this fluid 5 in order to protect the battery and / or the battery's mounting elements 50, 51 and / or the electrical and / or electronic components 53 from this fluid 5.

[0060] Although the battery is installed in the tray 10, which is arranged vertically at a height corresponding to the underbody area of ​​the vehicle, the battery tray 10 is watertight against water splashes and / or water ingress. In other words, the tray is at least partially under the partition 3, and a seal is provided between the tray 10 and the partition 3, in particular via the gasket 52 extending over the entire junction between the tray 10 and the partition 3. As a reminder, the Z2 area is subject to water splashes, or even immersion, particularly in the case of fording.

[0061] Thus, although the tank 10 is sealed and arranged in an immersion zone, the tank includes the evacuation means 20. As seen previously, according to the first embodiment in particular, the evacuation means includes the non-return valve 21 allowing the fluid 5 to exit if necessary, while preventing the entry of water.

[0062] Alternatively or in addition, the receptacle 40 is provided to collect the liquid 5 if necessary. Optionally, the liquid 5 passes through the non-return valve 21 before flowing into the receptacle 40. Alternatively, the drainage means does not include a valve but a simple hole, or even several holes. As mentioned, the receptacle 40 ensures the retention and storage of the liquid 5 so that the liquid 5 does not remain or spread to the bottom of the container 10. As mentioned, optionally, the bottom 12 of the container includes grooves or ribs 31, 32 to prevent any stagnation of liquid 5 under the battery 4, at least in contact with the battery 4 and / or cables and / or electronic components and / or electrical components 53 such as fuses, for example.

[0063] Preferably, the receptacle is fixed in a removable manner, for example by screwing ([Fig.7]) or by clipping, preferably via a small-amplitude rotation R (Figures 4 to 6). Thus, emptying or draining the receptacle 40 is easy and quick.

[0064] As illustrated in particular in figures 8, 10 and 12, the network of ribs 47 extending from the bottom 400 towards the inside of the receptacle 40 prevents the movement of the liquid 5 trapped inside, particularly during turns and / or braking and / or acceleration and / or when the vehicle 1 is going up or down steep inclines. Thus, the liquid 5 is prevented from spreading over all the internal surfaces of the receptacle 40, the liquid being concentrated at the bottom of the receptacle.

[0065] Thanks to the solution, although the battery contains lead, for example, and electrolyte liquid 5 is likely to leak from the battery in case of malfunction, the tray 10 includes a drain so that the liquid 5 does not come not in contact with the battery and / or cables and / or electronic components and / or electrical components 53. Simultaneously, the battery and these components 53 are kept protected from splashes of water or immersion in water and / or mud in case of fording and / or flooding. Electrolyte fluid is therefore prevented from coming into contact with such cables and / or electronic components and / or electrical components located near the battery. Thus, the fluid 5 cannot degrade the insulation of such cables and / or components, or even the components 53 themselves. This prevents any risk of malfunction.

[0066] As a note, the solution therefore achieves the objective of evacuating leaking liquid from a battery in a simple and reliable manner and has the advantage of being able to be used on floating vessels, trains, or other types of motorized vehicles, namely trucks, buses, utility vehicles or even motorized two-wheelers, including a battery that may leak and is installed in an area subject to water spray or even immersion.
