Description
L’invention se rapporte à un boîtier pour batterie de véhicule comprenant un capot et un panneau. Le boîtier selon l’invention est destiné plus particulièrement aux véhicules automobiles hybrides ou électriques.The invention relates to a box for a vehicle battery comprising a cover and a panel. The box according to the invention is intended more particularly for hybrid or electric motor vehicles.
Il est connu de l’état de la technique que les batteries électriques équipant les véhicules, notamment automobiles, ont tendance à produire de la chaleur qu’il est nécessaire d’évacuer afin de prévenir tout risque d’endommagement des pièces environnant de telles batteries électriques. D’une manière générale, les véhicules électriques ou hybrides comportent des batteries ayant une plus grande capacité de stockage d’énergie électrique que les véhicules à moteur fonctionnant, notamment, à l’essence ou au gasoil. Les batteries équipant de tels véhicules produisent ainsi plus de chaleur. Il est alors ajouté un pulseur d’air permettant de faire circuler un flux d’air frais ayant un pour rôle de les refroidir. L’inconvénient majeur d’un pulseur d’air est qu’il émet un bruit important. Il a ainsi été proposé dans l’art antérieur un couvercle permettant d’atténuer ses perturbations acoustiques. Un tel couvercle est décrit dans la demande de brevet EP 1 153 803 A1. On peut apercevoir sur la figure 9 de cette demande de brevet, le couvercle 119 disposé dans une partie de la chambre d’entrée d’air 106. Le couvercle 119 sert non seulement de plaque insonorisante pour réduire le bruit de fonctionnement du pulseur d’air 31, mais également de protection pour réduire la quantité de corps étrangers introduits dans le manchon d’air 110 du pulseur d’air 31. En outre, comme on peut le voir sur la figure 3, l’unité de batterie 24 est disposée dans un boîtier de batterie 30 constitué d’un boîtier inférieur 26 et d’un boîtier supérieur 28. Une telle configuration permet à l’air de circuler dans un bloc batterie 10 comprenant un conduit d’admission d’air 34 et un conduit d’évacuation d’air 38 et ainsi refroidir l’unité de batterie 24.It is known from the state of the art that the electric batteries fitted to vehicles, in particular automobiles, tend to produce heat which it is necessary to evacuate in order to prevent any risk of damage to the parts surrounding such batteries. electrical. In general, electric or hybrid vehicles have batteries with a greater electrical energy storage capacity than motor vehicles running, in particular, on gasoline or diesel. The batteries fitted to such vehicles thus produce more heat. An air blower is then added to circulate a flow of fresh air whose role is to cool them. The major disadvantage of an air blower is that it emits a lot of noise. It has thus been proposed in the prior art a cover making it possible to attenuate its acoustic disturbances. Such a lid is described in patent application EP 1 153 803 A1. Can be seen in Figure 9 of this patent application, the cover 119 disposed in part of the air inlet chamber 106. The cover 119 not only serves as a soundproofing plate to reduce the operating noise of the pulser of air 31, but also protective to reduce the amount of foreign bodies introduced into the air sleeve 110 of the air blower 31. In addition, as can be seen in Figure 3, the battery unit 24 is arranged in a battery box 30 consisting of a lower box 26 and an upper box 28. Such a configuration allows air to circulate in a battery box 10 comprising an air intake duct 34 and an air intake duct vent 38 and thereby cool the battery unit 24.
Les inconvénients principaux des boîtiers de batterie de l’état de la technique sont la complexité d’assemblage et de démontage, l’augmentation de la masse embarquée par les véhicules et, par conséquent, l’augmentation de leur consommation énergétique. En effet, ces boîtiers comportent de nombreuses pièces à assembler et présentent des masses non négligeables par rapport aux autres éléments composant un véhicule.The main drawbacks of state-of-the-art battery boxes are the complexity of assembly and disassembly, the increase in the mass carried by vehicles and, consequently, the increase in their energy consumption. Indeed, these boxes include many parts to be assembled and have significant masses compared to the other components of a vehicle.
Le but de l’invention est donc de pallier les inconvénients de l’art antérieur en proposant un boîtier pour batterie de véhicule plus simple à assembler et à démonter et également plus léger.The object of the invention is therefore to overcome the drawbacks of the prior art by proposing a housing for a vehicle battery that is simpler to assemble and disassemble and also lighter.
Pour ce faire, l’invention se rapporte ainsi, dans son acceptation la plus large, à un boîtier pour batterie de véhicule comprenant un capot et un panneau destiné à être posé sur une surface sensiblement plane dudit véhicule environnant ladite batterie, ledit capot comprenant une paroi supérieure, une première paroi latérale liée à ladite paroi supérieure et une seconde paroi latérale liée à ladite paroi supérieure, caractérisé en ce que ladite première paroi latérale comporte un premier bord bas, ledit boîtier comprenant en outre au moins une fixation quart de tour comportant un élément mâle solidaire dudit capot et un élément femelle solidaire dudit panneau, ledit capot comportant en outre au moins partiellement sur une surface intérieure une feuille métallique apte à réduire les effets d’un champ électromagnétique produit par un circuit électrique relié à ladite batterie, ledit panneau comportant en outre une cavité accueillant ledit premier bord bas.To do this, the invention thus relates, in its broadest sense, to a box for a vehicle battery comprising a cover and a panel intended to be placed on a substantially flat surface of said vehicle surrounding said battery, said cover comprising a top wall, a first side wall bonded to said top wall and a second side wall bonded to said top wall, characterized in that said first side wall has a first bottom edge, said housing further comprising at least one quarter-turn fastener comprising a male element secured to said cover and a female element secured to said panel, said cover further comprising at least partially on an inner surface a metal sheet capable of reducing the effects of an electromagnetic field produced by an electrical circuit connected to said battery, said panel further comprising a cavity accommodating said first bottom edge.
Grâce au système selon l’invention, le véhicule a une masse embarquée plus faible et les opérations de montage et démontage du boîtier pour batterie sont plus simples. En effet, le capot a pour avantage de réduire les effets d’un champ électromagnétique généré par un circuit électrique tout en étant léger et ceci grâce à une feuille métallique de faible épaisseur disposée sur sa surface intérieure. Le capot peut ainsi être fait d’un matériau ayant une faible masse volumique, tel que du plastique. En outre, l’épaisseur de la feuille métallique peut, par exemple, être comprise entre 0,6 mm et 0,8 mm afin d’en optimiser la masse.Thanks to the system according to the invention, the vehicle has a lower on-board mass and the assembly and disassembly operations of the battery box are simpler. Indeed, the cover has the advantage of reducing the effects of an electromagnetic field generated by an electrical circuit while being light and this thanks to a thin metal sheet arranged on its inner surface. The cover can thus be made of a material having a low density, such as plastic. In addition, the thickness of the metal sheet can, for example, be between 0.6 mm and 0.8 mm in order to optimize its mass.
Avantageusement, ladite feuille métallique est faite d’un alliage d’aluminium.Advantageously, said metal sheet is made of an aluminum alloy.
Ainsi, le boîtier pour batterie est allégé et par conséquent la consommation énergétique dudit véhicule est diminuée.Thus, the battery box is lightened and consequently the energy consumption of said vehicle is reduced.
De préférence, ladite feuille métallique recouvre uniquement une face intérieure de ladite paroi supérieure.Preferably, said metal sheet covers only an inner face of said top wall.
De manière préférée ladite feuille métallique recouvrement quasiment, voire totalement, ladite surface intérieure.Preferably, said metal sheet covers almost, or even completely, said inner surface.
Selon un aspect préféré, l’angle que fait ladite première paroi latérale avec ladite paroi supérieure est plus important que l’angle que fait ladite seconde paroi latérale avec ladite paroi supérieure.According to a preferred aspect, the angle that said first side wall makes with said top wall is greater than the angle that said second side wall makes with said top wall.
Avantageusement, l’angle que fait ladite première paroi latérale avec ladite paroi supérieure est d’environ 110° et l’angle que fait ladite seconde paroi latérale avec ladite paroi supérieure est d’environ 105°.Advantageously, the angle that said first side wall makes with said top wall is about 110° and the angle that said second side wall makes with said top wall is about 105°.
De préférence, ladite cavité est formée par un premier bord intérieur dudit panneau et par une patte disposée parallèlement audit premier bord intérieur.Preferably, said cavity is formed by a first inner edge of said panel and by a tab arranged parallel to said first inner edge.
L’invention concerne également une batterie de véhicule recouverte par un boîtier, ladite batterie comportant une surface supérieure, ledit capot étant configuré de manière à créer une distance entre une face intérieure de ladite paroi supérieure et ladite surface supérieure.The invention also relates to a vehicle battery covered by a casing, said battery having an upper surface, said cover being configured so as to create a distance between an interior face of said upper wall and said upper surface.
La présente invention se rapporte en outre à un véhicule, notamment automobile, comprenant une batterie et comportant en outre un boîtier posé sur une surface sensiblement plane dudit véhicule, ledit boîtier recouvrant ladite batterie.The present invention further relates to a vehicle, in particular a motor vehicle, comprising a battery and further comprising a casing placed on a substantially flat surface of said vehicle, said casing covering said battery.
On décrira ci-après, à titre d’exemples non limitatifs, des formes d’exécution de la présente invention, en référence à la figure annexée sur laquelle :There will be described below, by way of non-limiting examples, embodiments of the present invention, with reference to the appended figure in which:
En référence à la figure 1, il est représenté schématiquement un boîtier 1 pour batterie mis en place sur une surface sensiblement plane 50 d’un véhicule automobile (non présenté), notamment hybride ou électrique, afin de couvrir une batterie 6 électrique. La surface sensiblement plane peut être, par exemple, le plancher 2 dudit véhicule. Dans la description de la présente invention, il faut comprendre que les termes « surface sensiblement plane » signifient que la surface est globalement plane, mais elle peut néanmoins comporter localement des zones creuses ou protubérantes. Le boîtier 1 comprend un capot 3 et un panneau 40 comportant une ouverture intérieure 41. Le boîtier 1 comprend en outre une fixation quart de tour 5. Les éléments mâle et femelle de la fixation quart de tour 5 sont respectivement solidaires dudit capot 3 et dudit panneau 40. Dans un mode de réalisation de l’invention, le panneau 40 est un revêtement de sol, tel qu’un tapis. Le capot 3 est fait d’un matériau plastique. Ainsi, le capot 3 est léger et simple à fabriquer. Le capot 3 comporte une paroi supérieure 30, sensiblement plane, une première paroi latérale 31 et une seconde paroi latérale 32, sensiblement planes également. Dans un mode de réalisation particulier de l’invention, l’angle que fait ladite première paroi latérale 31 avec ladite paroi supérieure 30 est plus important que l’angle que fait ladite seconde paroi latérale 32 avec ladite paroi supérieure 30. Dans un mode de réalisation spécifique, la première paroi latérale 31 présente un angle d’environ 110° par rapport à ladite paroi supérieure 30 et la seconde paroi latérale 32 présente un angle d’environ 105° par rapport à ladite paroi supérieure 30. Lorsque le boîtier 1 est disposé sous le siège conducteur ou passager dudit véhicule, cette configuration présente l’avantage de mettre en retrait le capot 3 par rapport audit siège et, ainsi, de le rendre moins visible. On aperçoit également sur la figure 1 un pulseur d’air 7 configuré pour produire un flux d’air destiné à refroidir ladite batterie 6. La paroi supérieure 30 du capot 3 comporte une face extérieure 33 et une face intérieure 34. Le capot 3 est configuré de manière à ce que ledit flux d’air puisse circuler entre ladite face intérieure 34 et la face supérieure 61 de ladite batterie 6. Pour ce faire, la face intérieure 34 est distante de la face supérieure 61. Il est ainsi créé une lame d’air de faible épaisseur. Dans un mode de réalisation particulier, l’épaisseur de ladite lame d’air, ou la distance entre ladite face intérieure 34 et ladite face supérieure 61, est comprise entre 5 mm et 10 mm. La configuration du capot 3 permet ainsi de réduire les nuisances sonores générées par ledit pulseur d’air 7. Le confort du conducteur ou des passagers dudit véhicule automobile est ainsi amélioré. Par ailleurs, le capot 3 comprend une surface intérieure 36 comportant une feuille métallique 35, par exemple, en aluminium. Dans un mode de réalisation particulier, la feuille métallique 35 recouvre quasiment entièrement, voire complétement, la surface intérieure 36 dudit capot 3. Dans un mode de réalisation alternatif, la feuille métallique 35 recouvre uniquement la face intérieure 34, dans sa totalité ou partiellement, et/ou la face intérieure 37 de la première paroi latérale 31, dans sa totalité ou partiellement, et/ou la face intérieure 38 de la seconde paroi latérale 32, dans sa totalité ou partiellement. Dans un mode de réalisation particulier, la feuille métallique a une épaisseur comprise entre 0,6 et 0,8 mm. Elle est solidarisée au capot 3, par exemple, par collage ou tout autre moyen de fixation permettant une tenue durable de la feuille métallique sur son substrat. Elle a pour avantage de réduire, voire supprimer, les effets du champ électromagnétique généré par le circuit électrique environnant la batterie 6 ou par la batterie 6 elle-même. Le panneau 40 comporte en outre une cavité 43 configurée pour recevoir un premier bord bas 39 dudit capot 3 disposé dans le prolongement de ladite première paroi latérale 31. La cavité 43 est formée par un premier bord intérieur 42 de l’ouverture intérieure 41 et une patte 44 disposée sensiblement parallèlement audit premier bord intérieur 42. Le panneau 40 comporte également un second bord intérieur 45. Dans un mode de réalisation particulier, l’élément femelle de la fixation quart de tour 5 est solidaire dudit second bord intérieur 45. La cavité 43 et la fixation quart de tour 5 permettent un montage et un démontage simplifié du capot 3. En effet, lors du montage, on vient glisser le premier bord bas 39 dans ladite cavité 43 et on tourne ensuite la fixation quart de tour 5 afin de fixer la capot 3 par rapport au panneau 40. Lors du démontage, on tourne la fixation quart de tour 5 en sens inverse et l’on vient ensuite retirer le premier bord bas 39 de la dite cavité 43. Dans un autre mode de réalisation, ledit panneau 40 comporte deux parties. Une première partie comporte la cavité 43 et une seconde partie comportant la partie femelle de ladite fixation quart de tour 5.Referring to Figure 1, there is shown schematically a housing 1 for battery set up on a substantially flat surface 50 of a motor vehicle (not shown), including hybrid or electric, to cover an electric battery 6. The substantially planar surface can be, for example, the floor 2 of said vehicle. In the description of the present invention, it should be understood that the terms "substantially flat surface" mean that the surface is generally flat, but it may nevertheless locally include hollow or protruding areas. The casing 1 comprises a cover 3 and a panel 40 comprising an internal opening 41. The casing 1 further comprises a quarter-turn fixing 5. The male and female elements of the quarter-turn fixing 5 are respectively secured to said cover 3 and to said panel 40. In one embodiment of the invention, panel 40 is a floor covering, such as a carpet. Cover 3 is made of a plastic material. Thus, the cover 3 is light and simple to manufacture. The cover 3 comprises an upper wall 30, substantially planar, a first side wall 31 and a second side wall 32, also substantially planar. In a particular embodiment of the invention, the angle that said first side wall 31 makes with said top wall 30 is greater than the angle that said second side wall 32 makes with said top wall 30. specific embodiment, the first side wall 31 has an angle of approximately 110° with respect to said upper wall 30 and the second side wall 32 has an angle of approximately 105° with respect to said upper wall 30. When the housing 1 is placed under the driver's or passenger's seat of said vehicle, this configuration has the advantage of recessing the cowl 3 with respect to said seat and, thus, of making it less visible. One also sees in FIG. 1 an air blower 7 configured to produce a flow of air intended to cool said battery 6. The upper wall 30 of the cover 3 comprises an outer face 33 and an inner face 34. The cover 3 is configured so that said air flow can circulate between said inner face 34 and the upper face 61 of said battery 6. To do this, the inner face 34 is remote from the upper face 61. There is thus created a blade thin air. In a particular embodiment, the thickness of said air gap, or the distance between said inner face 34 and said upper face 61, is between 5 mm and 10 mm. The configuration of the cover 3 thus makes it possible to reduce the noise pollution generated by said air blower 7. The comfort of the driver or the passengers of said motor vehicle is thus improved. Furthermore, the cover 3 comprises an inner surface 36 comprising a metal sheet 35, for example, aluminum. In a particular embodiment, the metal sheet 35 covers almost entirely, or even completely, the inner surface 36 of said cover 3. In an alternative embodiment, the metal sheet 35 only covers the inner face 34, in whole or in part, and/or the inner face 37 of the first side wall 31, in whole or in part, and/or the inner face 38 of the second side wall 32, in whole or in part. In a particular embodiment, the metal sheet has a thickness of between 0.6 and 0.8 mm. It is secured to the cover 3, for example, by gluing or any other fixing means allowing a durable hold of the metal sheet on its substrate. It has the advantage of reducing, or even eliminating, the effects of the electromagnetic field generated by the electric circuit surrounding the battery 6 or by the battery 6 itself. The panel 40 further comprises a cavity 43 configured to receive a first bottom edge 39 of said cover 3 arranged in the extension of said first side wall 31. The cavity 43 is formed by a first inner edge 42 of the inner opening 41 and a tab 44 disposed substantially parallel to said first inner edge 42. Panel 40 also includes a second inner edge 45. In a particular embodiment, the female element of the quarter-turn binding 5 is integral with said second inner edge 45. The cavity 43 and the quarter-turn fastener 5 allow simplified assembly and disassembly of the cover 3. Indeed, during assembly, the first bottom edge 39 is slid into said cavity 43 and the quarter-turn fastener 5 is then turned in order to fix the cover 3 with respect to the panel 40. During dismantling, the quarter-turn fixing 5 is turned in the opposite direction and the first bottom edge 39 is then removed from the said cavity 43. In another embodiment, said panel 40 has two parts. A first part includes the cavity 43 and a second part includes the female part of said quarter-turn fastener 5.
