Each battery is fixed to the support tray by means of a fixing flange resting on the upper part of the heels of the battery and a projection provided on a wall of the battery support tray also bearing on a heel of the battery. drums. Some of these batteries may be lead-acid type. However, during a rear impact of the vehicle 50km / h for example, the battery mounting flange may not be sufficient to retain the forces applied to the battery and therefore is not strong enough and rigid to firmly hold the battery in the support tray. The back wall of the support tray is not sufficiently strong and rigid either to retain the battery 3035046 2 during its retreat and absorb the energy of recoil due to impact. Added to this is the fact that acid leakage can occur in the case of lead-acid batteries and lead to a risk of corrosion of the fastening screws of the support tank, particularly for small batteries that allow these screws to appear. . 3.

This solution solves the aforementioned problems. In particular, this fixing and protection device makes it possible, on the one hand, when the retaining element is installed in the bottom of the battery support tray, to prevent the battery from falling back during an impact. The retaining element thus avoids the movement of the battery at least in the direction of impact, for example. On the other hand, such a device makes it possible to avoid, during the flow of corrosive acid from the battery that may occur during a failure or shock, a risk of corrosion of the fixing screws of the support tray. battery on the body structure of the vehicle by protecting the screws. Thus, there is no need to alter the structure of the support pan or the environment of the vehicle body structure to maintain the integrity of the battery during an impact. Furthermore, the retaining element by design is simple to manufacture, easily adaptable to the support tray and is inexpensive. According to other characteristics, the advantageous features of which will be apparent from the present description: the retaining element is removable; - The retaining element is arranged to be in contact with the rear wall of the battery support tray and one of the faces of the battery; The holding member is arranged to contact the rear wall of the battery holder and a vertical face of the battery; the retaining element is arranged to be in contact with the rear wall of the battery support tray and a lower face of the battery; - More specifically, the first part of the retaining element is in contact with the rear wall of the battery support tray and the vertical or lower face of the battery; The plug and the first part are formed in one piece; the plug and the first part each have an upper surface defining planes 4 parallel to one another; the retaining element comprises a second part movable with respect to the first part between: a first extended position in which the first and the second parts are arranged adjacently in a longitudinal direction of the first part; and a second folded position in which the first and second parts are arranged one above the other. - The second part is movable relative to the first part in a pivot connection axis parallel to the longitudinal direction of the first part; the second portion has an upper surface provided with fastening means configured to cooperate with complementary securing means of the upper surface of the first portion when the first and second portions are in the folded position; The first and second portions have a side surface provided with complementary securing means configured to cooperate with each other when the first and second portions are in the deployed position; The upper surface of the first part comprises an interface zone provided with fixing elements; at least the upper surfaces of the first part and the protective cap comprise means for preventing the battery from recoil; the protective cap has an inner surface opposite the upper surface from which extend outer and inner skirts, the outer and inner skirts respectively having an inner wall and an outer wall defining a groove; - The protective cap has a circular section.

DETAILED DESCRIPTION Referring to FIG. 1, is shown in perspective and schematically a battery 100 of small size (D1) mounted in a device 1 for fixing and protecting the battery comprising a support tray 2 of drums. The battery 100 comprises, in known manner, six faces 101, of which four vertical faces 101a here each carrying a heel 102 towards their lower end, a lower face 101b (FIG. 8) intended to be in contact with the bottom of the support tray (2). and an upper face 101c opposite to the lower face 101b. In FIG. 2, more specifically, the battery support tray 2 comprises a bottom 3 from which four walls, one of which has a rear wall 4a, a front wall 4b opposite the rear wall 4a and two side walls 4c, are raised. , 4d opposite to each other. To facilitate understanding of the invention, we consider that the bottom 3 of the support tray is elongated along a horizontal longitudinal axis X. Is also shown the transverse axis Y 3035046 7 which extends the bottom 3 at depth and which is perpendicular to the horizontal longitudinal axis X and a vertical axis Z along which the walls 4 extend from the bottom 3 and which is perpendicular to the horizontal longitudinal axis X and to the transverse axis Y so that these three axes X, Y, Z form a direct orthogonal coordinate system as illustrated in FIG. 2. The terms "front" and "rear" are defined with respect to the horizontal axis X, the terms "inferior", " are defined with respect to the Z axis and the term "lateral" is defined with respect to the Y axis. The support tray 2 is attached and secured to a vehicle body structure (not shown) by means of fastening means such as vi s 27 (Figure 1) in wells 5 provided in the bottom 3 of the support tray 2. The wells 5 are formed here of a cylindrical wall 6 rising from the bottom 3 of the support tray 2. The bottom 3 of the support tank 2 also comprises liquid evacuation channels 7 formed in the bottom 3. These discharge channels 20 7 allow the evacuation of the acid that can flow from the battery 100. The channels 7 are connected to a discharge port 8 located in the bottom 3 of the support tray 2 and are intended to drive the acid to the outside of the vehicle. The side wall 4c is provided with a protrusion 9 extending along its entire length while the opposite side wall 4d has a recess 10 for arranging and securing a fastening flange 11 (FIGS. 4). In FIG. 3 is illustrated the battery 100 30 supported by the bottom 3 in the battery support tray 2 and immobilized by the projection 9 bearing on the heel (not shown) of the face of the battery 100 facing the projection 9 The fixing flange 11 has a portion which bears on the upper part of the heel 102 of the face 101 of the battery which is oriented towards the wall 4d of the battery support tray 2 and the fastener is adjusted by means of a screw 16 or any other threaded element fixing the fixing flange 11 and the battery 100. The device 1 for fixing and protecting the battery also comprises a retaining element 12 as illustrated in FIGS. 3 and 4. The retaining element 12 is also arranged on the bottom 3 of the support tray 2 and in particular is configured to be arranged in contact with one of the faces 101 of the battery. By "retaining element" is meant an element to prevent movement of the battery in the battery holder and to maintain the integrity of the battery as well as the battery holder. The retaining element 12 is removable relative to the support tray 2. In this way, the retaining element 12 can be replaced in case of failure or deterioration. In FIG. 3, the retaining element 12 is arranged between the rear wall 4a of the support tray 2 and one of the faces 101 of the battery 101. More specifically, the retaining element is arranged between the rear wall 4a and the face 101 of the battery 100 which is oriented towards the rear wall 4a of the support tray 2. Advantageously, but not exclusively, the retaining element is arranged to be in contact with the rear wall 4a and a vertical face 101a of the battery. In FIGS. 5 and 6, the retaining element 12 comprises a first portion 13 extending in a longitudinal direction L1 (perpendicular to the X axis as shown in FIG. 5). The first portion 13 has an upper surface 14 defining a plane A and four sides 15 extending from this top surface 3035046 9 14. The first portion 13 here has a rectangular section. Advantageously, but not limitatively, the first portion 13 has a generally parallelepiped shape and in particular rectangular parallelepiped. In this way, the retaining element 12 can be easily mounted in the support tray 2 between the battery 100 and the rear wall 4a of the tray of the support 2. In particular, the first part 13 is in contact with the rear wall 4a and a face 101 of the battery.
    [0005] The retaining element 12 has a protective cap 17 or cover arranged at at least one free end of one side 15 of the first part 12. Here, two protective caps 17 are each arranged towards a corner on two sides 15 In particular, the plugs are located towards the same side 15, here lateral (in the direction L1), of the first part 13. The protective cap 17 and the first part 13 are formed of one piece. In other words, these are integrally formed so as to fabricate and mount the retainer 12 easily and quickly. The protective cap 17 has an upper surface 18 and an inner surface 19 opposite the upper surface 17. The upper surface 18 defines a plane B parallel to the plane of the upper surface 14 of the first portion 13. In other words the planes A and B of the upper surfaces 14, 18 are offset along the Z axis as shown in FIG. 5. With reference to FIGS. 7 and 8, the protective cap 17 comprises an outer skirt 20 which extends 30 from the inner surface 19 and having an inner wall 21 opposite an outer wall 22. An inner skirt 23 also extends from the inner surface 19 of the protective cap 17 and has an outer wall 24. The inner wall 21 of the outer skirt 20 and the outer wall 24 of the inner skirt 23 delimits a groove 25. The protective cap 17 and the outer skirt walls 20 and inner 23 have 5 here a section Circular. The inner skirt 23 has a conical shape to promote the fitting of the protective cap 17 in a well 5. The groove 25 is intended to receive the cylindrical wall 6 of the corresponding well 5 when the retaining element 12 is arranged in the tray of 10 battery support 2. In this way, the inner skirt 23 of the protective cap 17 extends inside the cylindrical wall 6 of the well 5. In particular, the outer wall 24 of the inner skirt 23 is in contact and is inserted in an adjusted manner. , or even with an inner face 26 of the cylindrical wall 6 of the well 5. In other words, the outer wall 24 of the inner skirt 23 has a diameter substantially equal to that of the inner face 26 of the wall. The inner wall 21 of the outer skirt 20 also includes a bead 28 bearing on the cylindrical wall 6 of the well 5 and allowing the jamming of the protective cap 17 in the well. Thus, each protective cap 17 covers the well 5 and in particular the fixing screw 27 which is housed therein with an "umbrella" effect so as to protect the screw 27 of the acid and therefore of the corrosion (see FIG. 8). The acid can then flow into the discharge channels 7 to the discharge port. The bead 28 also provides baffle protection against possible acid splashes. The inner skirt 23 is closed here by a wall 28 to provide robustness. The bead 102 of the battery 100 contacts a side side of the first portion 13 of the retaining member 3035046 11 during an impact. Moreover, the walls 24, 21 of the outer skirts 20 and inner 23 make it possible to transfer the forces due to the recoil of the battery 100 and to absorb the energy during the impact.
    [0006] The retainer 12 also includes a second movable portion 29 relative to the first portion 13 between: a first extended position in which the first 13 and second 29 portions are disposed adjacently in the longitudinal direction L1 (FIGS. 3 and 5); and a second folded position in which the first 13 and the second 29 portions are arranged one above the other (in a vertical longitudinal direction L2 with reference to Figures 4 and 6 and which is orthogonal to the direction L1). In other words, their upper surfaces 14, 30 are superimposed. Such a configuration allows the retaining element 12 to be adaptable to any type of battery. When the retaining element 12 is mounted in the support tray 2, the longitudinal direction L1 is parallel to the transverse axis Y and is orthogonal to the horizontal longitudinal axis X. Thus, when the second part 29 is deployed, the retaining member allows to retain and maintain the small battery 100 (D1) in the battery holder 2 in a rear impact. In other words, the retaining element prevents / prevents the displacement of the battery along one of the X, Y, Z axes, here the horizontal longitudinal axis X during a rear impact. Conversely, when the second portion 30 is folded, it allows to retain and maintain a battery 110 of medium size (D2) in the support tray 2 in a rear impact 3035046 12. For this, the first portion 13 has a width 11 (Figure 3) substantially equal to the space el (Figure 4) formed between the rear wall 4a (inner surface 5) and the face 101 of the battery 110 when the latter is immobilized in the support tray 2. In addition, the second portion 29 comprises a width 12 which is lower here than that of the first portion 13. When the second portion 29 is deployed, the retaining element 12 has a width 13 equal to those of the first part 13 and the second part 29, and the space e2 formed between the rear wall 4a (inner surface) and the face 101 of the battery 100 when the latter is immobilized in the support tray 2 .
    [0007] In particular, the second portion 29 is movable relative to the first portion 13 according to at least one axis C pivot connection parallel to the longitudinal direction L1. For the sake of simplicity and cost of manufacture, the pivot connection is made by thinning material between the first 13 and the second 29 parts. The retaining element 12 is made of a polymer or copolymer material. In particular, the polymeric material is selected from the group of thermoplastic polymeric materials, for example polypropylene (PP). According to one embodiment of the retaining element 13 illustrated in FIG. 9, the upper surface 14 of the first part 13 comprises an interface zone 37 provided with fastening elements 38. These fixing elements 38 may be holes for the attachment of fir-tree, a dovetail and / or a metal insert for fastening elements by screwing. Thus, this interface zone 37 with the fastening elements 38 allows the creation of additional fixing points for other inserts to be fixed in the vehicle. In one embodiment of the retaining element 12 shown in FIG. 10, the upper surface 30 of the second portion 29 is provided with fixing means configured to cooperate with complementary fastening means of the upper surface 14. of the first part 13 when the first 13 and second 29 10 parts are in the folded position. This configuration 29 makes it possible to firmly hold the second portion 29 in the folded position. In particular, the upper surface 14 of the first portion 13 has a lumen 31. The upper surface 30 of the second portion 29 has a lug 32 for snapping into the lumen 31 to retain the second portion 29 when the latter is in the folded position. According to another embodiment illustrated in FIG. 11, a lateral side of the first part 13 and a lateral side 33 of the second part 29 are provided with complementary fixing means configured so as to cooperate with each other when the second portion 29 parts is in the deployed position. This configuration makes it possible to firmly hold the second portion 29 in the deployed position. More specifically, the lateral side of the first side-opposed portion 15 disposed against the rear wall 4a has a plurality of openings 34. The lateral side 33 of the second portion 29 disposed facing the lateral side having the opposite side, Apertures 34 includes a plurality of pegs 35 each for clipping into an aperture of the plurality of apertures 34 when the second portion 29 is in the deployed position.
    [0008] According to yet another embodiment illustrated in FIG. 12, at least the upper surface 14 of the first part 13 and the protective cap 17 comprise anti-back-up means of the battery. These anti-back-up means are here formed by ridges 36. In this embodiment, the retaining element 12 is arranged to be in contact with the rear wall 4a of the battery support tray and a bottom face. drums. In this way, when a larger battery (not shown) (larger than the medium size battery 110 D2) is immobilized in the support tray 2, part of this battery covers the upper surfaces 18 of the cap The ridges 36 may be made of a polymeric material such as rubber. In this embodiment, the upper surfaces of the first parts and the protective cap 17 are defined in the same plane D. In this way, the ridges 36 prevent the sliding / moving of the battery during the retreat thereof. The retaining element 12 may advantageously but not exclusively be made integrally of rubber. The invention is described in the foregoing by way of example. It is understood that one skilled in the art is able to realize different embodiments of the invention, for example by associating the various characteristics above taken alone or in combination, without departing from the scope of the invention. invention.
