Definitions
- Kit comprising a thermal battery for a motor vehicle and a battery holder
- the present invention relates to an assembly comprising a support on which is disposed a thermal battery.
- the present invention finds its applications particularly in the field of motor vehicles
- thermal batteries are used for heating the passenger compartment of electric and hybrid vehicles.
- these batteries are used to preheat the heat transfer fluid of the heating radiator, engine oil or gearbox oil.
- Thermal batteries must comply with chemical, thermal and mechanical safety standards.
- the thermal battery is subjected to vibrations transmitted by the vehicle during travel.
- the thermal batteries comprise a heat storage chamber which constitutes the internal part of the battery and an insulating outer envelope.
- a known fixing system solution is to fix a support directly to the storage enclosure, for example by welding or brazing. Therefore, whatever the position of the support on the storage enclosure, the support passes through the insulating outer casing of the battery.
- This solution has the particular disadvantages of degradation of insulation performance and deterioration of the insulation itself. In addition, this generates thermal bridges between the external environment to the battery and the internal storage enclosure of this battery.
- One of the aims of the present invention is therefore to at least partially overcome the drawbacks of the state of the art by proposing a thermal battery mounting bracket to eliminate the thermal losses induced by the fastening system while maintaining a good fixation from the battery to the chassis of the vehicle and reducing the vibration stresses to the battery.
- the present invention thus relates to an assembly comprising a thermal battery for a motor vehicle and a support of said battery adapted to be attached to the vehicle, characterized in that said support comprises a receiving base on which said battery is disposed, said base comprising means for holding said battery on said base.
- the base comprises at least one damping element in contact with said battery.
- the retaining means are stops capable of holding the battery on at least one of its faces.
- the damping element is located on at least one of the retaining means in contact with said battery.
- the damping element is located on the part of the base on which said battery rests.
- the support comprises ribs mechanical reinforcement.
- the support comprises means for holding the battery on the support.
- the holding means comprise at least one strap.
- the holding means comprise at least one peripheral rigid link to the battery connected to the support.
- the battery is held in the support with a plate fixed to the support and bearing on the face of the battery opposite the base.
- the support comprises at least one molded part in a plastic material.
- the support comprises at least one part formed of stamped metal.
- the support is a mechanically welded assembly.
- the support comprises holes that can be used as a point of screwing or riveting of the support on the chassis of a vehicle.

- the battery 1 comprises a lower face 4 and an upper face 5 on which are located the inlet / outlet pipes 55 and 56 of the battery 1 allowing the circulation of a coolant for charging and discharging the heat battery 1. It also comprises two large lateral faces 52, 54 and two small lateral faces 51, 53, all adjacent to the faces 4 and 5.
- the faces 4 and 5 have a length L1 and a width L2 and are spaced from each other by a height H.
- FIGS 2a and 2b illustrate a thermal battery support 6 according to a first embodiment.
- the support 6 is composed of three elements 14a, 14b and 12.
- the first element 14a which composes the support 6 is a metal piece in the form of a flat hook in three parts: a large end, a central part and a small end, the two folding angles between two adjacent parts being substantially straight.
- the large end of the element 14a is a fastening bar 10.
- the central part of the element 14a is a crosspiece 17.
- the small end of the element 14a is a longitudinal stop 15.
- the longitudinal stop 15 and the fixing bar 10 are substantially parallel.
- This fixing bar 10 comprises at least one fixing hole 26 close to its free end. It also comprises a flat protrusion 27 in the form of a lobe, contained in the plane of the fixing bar at the location of the protuberance 27, the protuberance 27 being situated approximately at a height H of the cross-member 17 and located on one side determined from the fixing bar 10.
- the second element 14b which composes the support 6 is identical to the first element 14a with the difference that the protrusion 27 points to the opposite side to that towards which the protuberance 27 of the element 14a points.
- the elements 14a and 14b being similar, the references of the element 14a are indifferently applied to the elements 14a and 14b.
- the third element 12 which composes the support 6 is a flat metal part comprising a U-shaped portion 12a and an L-shaped portion 12b.
- Part 12a comprises a central cross member 16 and two lateral stops 13 pointing in the same direction, arranged at each end of the crossmember 16 and bent at right angles to the crosspiece 16.
- Part 12b includes a reinforcement 161 and an attachment bar 162 disposed perpendicular to the reinforcement 161.
- the reinforcement 161 is connected to the crossmember 16 at its center, the reinforcement 161 and the crossmember 16 being in the same plane and perpendicular to each other.
- the fixing bar 162 is located in a plane perpendicular to the cross member 16 and to the lateral stops 13. The end of the fixing bar 162 points in a direction opposite to the direction in which the lateral stops 13 point.
- fastener 162 includes a fixing hole 163.
- the elements 14a and 14b are connected to the element 12 so that:
- cross members 17 of the elements 14a and 14b are in contact and perpendicular to the crossmember 16 and arranged on either side of the reinforcement 161,
- the protuberances 27 of the elements 14a and 14b are arranged on the outside of the fastening bars 10,
- the longitudinal stops 15 are on the same side of the crossbar 16 as the reinforcement 161 and the fixing bar 162.
- Such an assembly of the three elements 14a, 14b and 12 form the support 6 comprising two fixing bars 10 and a receiving base 7 adapted to receive a battery.
- the two fixing bars 10 of the support 6 are the two fixing bars
- the base 7 comprises:
- a bottom 8 comprising the two crosspieces 17, the crosspiece 16, the reinforcement 161, retaining means comprising the two lateral abutments 13 and the two longitudinal abutments 15,
- the battery 1 is placed on the bottom 8 of the base 7.
- the bottom 8 is in a plane parallel to the lower face 4 of the battery 1 with which
- the retaining means 13, 15 are located in several places around the base so as to hold the battery on its three faces 51, 52, 53.
- the fixing bars 10 hold the battery on its fourth face 54.
- the lateral stops 13 and the longitudinal stops 15, associated with the fixing bars 10 prevent the battery from sliding on the bottom 8 of the base 7.
- the dimensions of the bottom 8 of the base 7 must be slightly greater than those of the lower face 4 of the battery.
- the length of the cross-member 16 is slightly greater than the length L1 of the face 4 and the length of the cross-member 17 is slightly greater than the width L2 of the face 4.
- the term "dimension slightly greater than another" means the difference between the two dimensions is equal to a mechanical clearance, the need being to be able to put the battery 1 on the base 7 without mechanical stress while ensuring that the retaining means 13, 15 and the fixing bars 10 are at least in part in contact and / or abutment with the faces 51, 52, 53, 54 of the battery 1.
- the two elements 14a and 14b of the support 6 comprise ribs 22 in order to reinforce it mechanically.
- the fastening bars 10 and the longitudinal stops 15 are thus reinforced.
- the location of the ribs on the support is not limiting.
- the element 12 of the support 6 may also have ribs. More generally, all the parts constituting the support 6 may comprise such ribs, particularly at the junction 23 between the retaining means 13, 15 and the bottom 8 of the base 7.
- the ribs 22 may be made by stamping (as illustrated in Figures 2a, 2b, 3 and 4), molding, welding or brazing.
- the support is intended to be fixed to the chassis of the vehicle. Therefore, to limit the impact of the vibrations of the car on the battery 1, dampers 24 are disposed on the cross members 17 of the base 7. This location is not limiting. Any part of the support 6 in contact with the battery 1 may advantageously be covered with damping elements 24, since the battery undergoes vibrations in the three dimensions of the space. Depending on the location of the dampers 24, it may be necessary to take into account their thickness in order to adjust the dimensions of the base 7, the simple mechanical clearance provided between the battery 1, 201 and the base 7, 107, 207 may not be longer suffice.
- the fixing holes 26, 163 of the support 6 make it possible to fix the support 6 to the chassis of the vehicle. These fixing holes 26, 163 are used as a point of screwing or riveting of the support 6 on the frame. The location and shape of the fixing holes 26, 163 and the fixing bars 10, 162 are not limiting and depend on the integration of the support in the vehicle.
- slots 20 on the protuberances 27 and slots 21 on the longitudinal stops 15 are provided for receiving straps 25.
- the straps 25 hold the battery 1 on the support 6 to prevent it from tilting the base 7.
- the straps 25 are attached to the support 6 slots 20 and 21.
- the straps 25, the lateral stops 13 and the longitudinal stops 15 prevent the battery 1 from slipping and tilting from its support 6, without disturbing the structure of the battery 1.
- the system for connecting an external circuit to the inlet / outlet pipes 55 and 56 of the battery 1 may be sufficient to prevent the battery 1 from tilting from its base 7.
- the straps 25 are optional.
- the support 6 of the invention does not create thermal bridges between the storage chamber 2 of the battery 1 and the external environment of the battery 1. In fact, the insulation of the outer casing 3 of the battery 1 is not impaired (in particular by brazed fastening means on the internal chamber of the battery).
- the base 107 is different from the base 7 of the first embodiment.
- the base 107 does not include the two lateral stops 13 of the base 7.
- the longitudinal stops 115a, 115b are similar to the longitudinal stops 15 of the support 6 of Figures 2a, 2b and 3 with the difference that they are higher. Due to the height of the longitudinal stops 115a, 115b, the tilting of the battery 1 of the base 107 is limited.
- the base 107 having no lateral stops to retain the battery 1 on its faces 51 and 53, the battery 1 could be likely to slide on its base 107. It is particularly to overcome this problem that a rigid link device 30 is added.
- This peripheral link 30 is connected to the longitudinal stops 115a, 115b of the support 106.
- the peripheral link 30 can also be connected to the fixing bars 110a, 110b of the support 106.

- the peripheral link 30 can be interrupted and cover the periphery from the first fixing bar 110a to the first longitudinal stop 115a and from the second longitudinal stop 115b to the second fixing bar 110b.
- a holding plate 31 is added.
- the holding plate 31 is Z-shaped with both angles straight.
- the first portion 311 of the holding plate 31 is pressed on the face 5 of the battery, the central portion 312 is attached to the peripheral link 30 and is therefore against a portion of the face 52 of the battery 1.
- the peripheral link is not interrupted between the longitudinal stops 115a and 115b and the holding plate is located in the middle of the face 52 of the battery 1.
- the third part of the retaining plate 31 is a fixing bar 313 pierced with a hole 314 allowing it to be fixed to the chassis of the vehicle.
- the holding plate 31 makes it possible to block the battery 1 on its support 106 and proposes a third point of attachment of the support 106 on the chassis of the vehicle, the first two attachment points being the holes 126, equivalent to the holes 26 of the first embodiment.
