DESCRIPTION DESCRIPTION
TITRE : SYSTEME DE FIXATION DE BATTERIES DE DIFFERENTES HAUTEURS, VEHICULE ET PROCEDE SUR LA BASE D’UN TEL SYSTEME TITLE: SYSTEM FOR ATTACHING BATTERIES OF DIFFERENT HEIGHTS, VEHICLE AND METHOD BASED ON SUCH A SYSTEM
La présente invention revendique la priorité de la demande française N°2201079 déposée le 08.02.2022 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application No. 2201079 filed on 08.02.2022, the content of which (text, drawings and claims) is incorporated herein by reference.
L’invention se rapporte au domaine des dispositifs et systèmes de fixation de batterie, en particulier pour des batteries de différentes hauteurs. L’invention concerne en outre le domaine des procédés de fixation de telles batteries, des structures de châssis et des véhicules sur la base de tels systèmes. The invention relates to the field of battery fixing devices and systems, in particular for batteries of different heights. The invention further relates to the field of methods for attaching such batteries, chassis structures and vehicles based on such systems.
Le demandeur a initié un projet de véhicule automobile dénommé « véhicule O2C ». Dans le cadre de la réalisation de ce véhicule, deux configurations de batteries à 12V sont à envisager au même emplacement, l’une à 10Ah, et l’autre à 16Ah. Ces batteries ont les mêmes dimensions en longueur (suivant un axe X) et en largeur (suivant un axe Y). La différence entre les deux batteries est au niveau de la hauteur (suivant un axe Z). The applicant has initiated a motor vehicle project called “O2C vehicle”. As part of the construction of this vehicle, two configurations of 12V batteries are to be considered in the same location, one at 10Ah, and the other at 16Ah. These batteries have the same dimensions in length (along an X axis) and in width (along a Y axis). The difference between the two batteries is at the level of the height (along a Z axis).
Le demandeur a proposé un système de fixation pour une batterie B1 à 4Ah, comprenant une sangle métallique S, et deux pattes soudées P sur un châssis C de véhicule automobile. Ce système est illustré en figure 1 . The applicant has proposed a fastening system for a 4Ah battery B1, comprising a metal strap S, and two lugs P welded to a motor vehicle chassis C. This system is illustrated in figure 1 .
Malheureusement, cette solution de l’art antérieur ne permet pas de prendre en compte une diversité de batteries en termes de hauteurs en Z comme dans le projet de véhicule O2C. Dans ce projet, la batterie à 10Ah a un poids de 4,25 kg et mesure 150 x 90 x 130 mm (L x l x H) ; tandis que la batterie à 16Ah a un poids de 5,5 kg et mesure 150 x 90 x 160 mm. Unfortunately, this prior art solution does not take into account a diversity of batteries in terms of heights in Z as in the O2C vehicle project. In this project, the 10Ah battery weighs 4.25 kg and measures 150 x 90 x 130 mm (L x W x H); while the 16Ah battery has a weight of 5.5 kg and measures 150 x 90 x 160 mm.
Par ailleurs, la solution de l’art antérieur présente également un potentiel risque électrique (dit « risque CCA ») au niveau des cosses batterie. Furthermore, the solution of the prior art also presents a potential electrical risk (known as “CCA risk”) at the level of the battery terminals.
Ainsi, un objectif de l’invention est de proposer une solution permettant de fixer des batteries de différentes hauteurs à un châssis de véhicule automobile, avec le même système de fixation. Thus, an objective of the invention is to propose a solution making it possible to fix batteries of different heights to a motor vehicle chassis, with the same fixing system.
Pour atteindre cet objectif, l’invention propose un système de fixation de batterie sur un châssis de véhicule automobile, le système de fixation comprenant To achieve this objective, the invention proposes a battery fixing system on a motor vehicle chassis, the fixing system including
- deux pattes soudées au châssis, configurées pour encadrer et maintenir la batterie latéralement, sur une face arrière et par le dessous, - two brackets welded to the chassis, configured to frame and hold the battery laterally, on a rear face and from below,
- une sangle métallique configurée pour encadrer et maintenir la batterie latéralement, sur une face avant et sur le dessus, dans lequel la sangle métallique comporte deux structures latérales de fixation coopérant avec des points de fixation latéraux pour une fixation solidaire au châssis, et une structure supérieure de fixation coopérant avec un point de fixation supérieur pour une fixation solidaire au châssis, au-dessus des points de fixation latéraux, et dans lequel le système de fixation comprend différentes hauteurs de fixation pour chacun des points de fixation. - a metal strap configured to frame and hold the battery laterally, on a front face and on the top, in which the metal strap comprises two lateral fixing structures cooperating with lateral fixing points for fixed fixing to the chassis, and a structure upper fixing cooperating with an upper fixing point for fixed fixing to the chassis, above the side fixing points, and in which the fixing system comprises different fixing heights for each of the fixing points.
En particulier, les pattes ont une structure ouverte sur le dessus pour être adaptées à plusieurs hauteurs de batterie, et la sangle a une structure fermée sur le dessus pour maintenir l’une ou l’autre batterie par le dessus. In particular, the legs have an open structure on the top to be adapted to several battery heights, and the strap has a closed structure on the top to hold one or the other battery from above.
Ainsi, le système de fixation batterie à 12V proposé est compatible avec différentes hauteurs de batterie, il permet de maintenir en position la batterie suivant les trois axes X, Y et Z, de la retenir en cas de choc avant ou arrière, et d’améliorer la protection des cosses batterie vis-à-vis du risque électrique. Thus, the proposed 12V battery fixing system is compatible with different battery heights, it allows the battery to be held in position along the three axes X, Y and Z, to retain it in the event of a front or rear impact, and to improve the protection of the battery terminals against electrical risk.
Avantageusement, le système de fixation permet d’assurer la compatibilité d’une seule solution de fixation avec deux versions de batterie différentes, tout en assurant le maintien de la batterie en tenue vibratoire et aux chocs, et la protection contre les risques électriques au niveau des cosses batterie. Advantageously, the fixing system makes it possible to ensure the compatibility of a single fixing solution with two different battery versions, while ensuring that the battery is maintained in vibration and shock resistance, and protection against electrical risks at the level battery terminals.
Le maintien de la batterie dans l’axe vertical Z sur le dessus se fait avec un crochet supérieur, ici sous forme patte vissée, qui pourra être fixée suivant deux positions, en fonction de la hauteur de la batterie. Maintaining the battery in the vertical axis Z on the top is done with an upper hook, here in the form of a screwed tab, which can be fixed in two positions, depending on the height of the battery.
En outre, l’invention permet de limiter le besoin de différents systèmes de fixation de batterie pour des batteries différentes. Elle permet également de garantir l’interchangeabilité entre une batterie 10Ah et 16Ah avec le même système de fixation. Furthermore, the invention makes it possible to limit the need for different battery fixing systems for different batteries. It also guarantees interchangeability between a 10Ah and 16Ah battery with the same mounting system.
Selon une variante, les points de fixation latéraux sont disposés sur le châssis, le point de fixation supérieur est disposé sur une patte, et le châssis et ladite patte comportent lesdites différentes hauteurs de fixation pour chacun des points de fixation. La fixation supérieure sur la patte permet d’avoir une bonne tenue sur le dessus de la batterie sans avoir besoin de fixer un crochet supérieur de la sangle sur une autre pièce du châssis avec deux hauteurs de points de fixation supérieurs. According to a variant, the side attachment points are arranged on the chassis, the upper attachment point is arranged on a bracket, and the chassis and said bracket includes said different fixing heights for each of the fixing points. The upper fixing on the leg allows to have a good hold on the top of the battery without the need to fix an upper hook of the strap on another part of the chassis with two heights of upper fixing points.
Selon une variante, les pattes comprennent une branche horizontale pour maintenir la batterie par le dessous. En particulier, il y a une branche horizontale sur chacune des deux pattes. Cela permet de soutenir la batterie par le dessous en la faisant reposer sur les branches horizontales. According to a variant, the legs include a horizontal branch to hold the battery from below. In particular, there is a horizontal branch on each of the two legs. This allows the battery to be supported from below by resting it on the horizontal branches.
Selon une variante, la sangle métallique comprend deux crochets latéraux pour encadrer et maintenir la batterie latéralement. Cela permet d’améliorer la tenue de la batterie sur la face avant et latéralement. Alternatively, the metal strap includes two side hooks to frame and hold the battery laterally. This improves the holding of the battery on the front and laterally.
De préférence, les crochets latéraux sont alignés horizontalement. Preferably, the side hooks are aligned horizontally.
Selon une variante, la sangle métallique comprend un crochet supérieur pour encadrer et maintenir la batterie sur le dessus. Cela permet d’améliorer la tenue de la batterie verticalement sur le dessus. Alternatively, the metal strap includes a top hook to frame and hold the battery on top. This improves the hold of the battery vertically on top.
Selon une variante, la sangle métallique encadre latéralement les pattes.According to a variant, the metal strap laterally frames the legs.
L’invention concerne en outre un châssis de véhicule automobile comprenant un système de fixation selon l’invention. The invention further relates to a motor vehicle chassis comprising a fastening system according to the invention.
Un autre objet de l’invention concerne un véhicule automobile comprenant un système de fixation selon l’invention. Another object of the invention relates to a motor vehicle comprising a fastening system according to the invention.
L’invention porte en outre sur un procédé de fixation d’une batterie parmi des batteries de différentes hauteurs, sur un châssis de véhicule automobile, au moyen d’un système de fixation selon l’invention, caractérisé en ce qu’il comprend des étapes pour : The invention further relates to a method for fixing a battery among batteries of different heights, on a motor vehicle chassis, by means of a fixing system according to the invention, characterized in that it comprises steps for:
- sélectionner une batterie d’une hauteur donnée, - select a battery of a given height,

L’invention concerne un système de fixation de batterie, en particulier pour des batteries B1 ou B2 de différentes hauteurs. Dans l’exemple illustré, la batterie B1 est celle qui a la plus petite hauteur. L’invention concerne en outre un procédé de fixation de telles batteries, ainsi qu’un châssis et un véhicule sur la base d’un tel système. The invention relates to a battery fixing system, in particular for B1 or B2 batteries of different heights. In the example shown, battery B1 is the one with the smallest height. The invention further relates to a method for attaching such batteries, as well as a chassis and a vehicle based on such a system.
Le système de fixation de batterie permet de solidariser la batterie à un châssis C de véhicule automobile, tout en étant adapté à des batteries B1 , B2 de différentes hauteurs. The battery fixing system makes it possible to secure the battery to a chassis C of a motor vehicle, while being adapted to batteries B1, B2 of different heights.
Le système de fixation comprend deux pattes P soudées au châssis C. Les pattes P sont configurées pour encadrer et maintenir la batterie B1 , B2 latéralement, sur une face arrière et en dessous de la batterie B1 ou B2. On peut envisager une structure de fixation unique comportant ces pattes. En particulier, les pattes de fixation P comprennent chacune une branche horizontale BH pour maintenir la batterie B1 , B2 par le dessous. The fixing system comprises two lugs P welded to the frame C. The lugs P are configured to frame and hold the battery B1, B2 laterally, on a rear face and below the battery B1 or B2. It is possible to envisage a single fixing structure comprising these tabs. In particular, the fixing lugs P each comprise a horizontal branch BH to hold the battery B1, B2 from below.
Le système de fixation comprend en outre une sangle métallique S configurée pour encadrer et maintenir la batterie B1 , B2 latéralement, sur une face avant et sur le dessus. The fastening system further comprises a metal strap S configured to frame and hold the battery B1, B2 laterally, on a front face and on the top.
La sangle métallique S comprend deux crochets latéraux CL pour encadrer et maintenir la batterie B1 ou B2 latéralement. Les crochets latéraux CL sont alignés horizontalement. Par ailleurs, la sangle métallique S comprend un crochet supérieur BS pour encadrer et maintenir la batterie B1 ou B2 sur le dessus, à savoir sur une face supérieure de ladite batterie B1 ou B2. De plus, la sangle métallique S encadre latéralement les pattes P. The metal strap S includes two side hooks CL to frame and hold the battery B1 or B2 laterally. The CL side hooks are aligned horizontally. Furthermore, the metal strap S comprises an upper hook BS to frame and hold the battery B1 or B2 on top, namely on an upper face of said battery B1 or B2. In addition, the metal strap S frames the legs P laterally.
Selon l’invention, la sangle métallique S comporte deux structures latérales de fixation SD, SG coopérant avec des points de fixation latéraux respectifs CD, CG disposés sur le châssis C. La sangle métallique S comporte en outre une structure supérieure de fixation SS coopérant avec un point de fixation supérieur PS disposé sur une extension verticale EP d’une pate P vers le haut, ici la patte gauche. According to the invention, the metal strap S comprises two lateral attachment structures SD, SG cooperating with respective lateral attachment points CD, CG arranged on the frame C. The metal strap S further comprises an upper attachment structure SS cooperating with an upper attachment point PS placed on a vertical extension EP of a leg P upwards, here the left leg.
Comme on peut le voir sur les figures 4 et 6, le crochet supérieur BS reposant sur la batterie B1 ou B2 peut comporter un retour, ici horizontal vers la gauche, de sorte à rejoindre l’extension verticale de la patte P de fixation. As can be seen in Figures 4 and 6, the upper hook BS resting on the battery B1 or B2 may include a return, here horizontal to the left, so as to join the vertical extension of the fixing lug P.
Le point de fixation supérieur PS est disposé sensiblement au-dessus des points de fixation latéraux CD, CG, de préférence au-dessus de la batterie B1 ou B2. Ceci est mis en oeuvre grâce à l’extension verticale EP. The upper attachment point PS is arranged substantially above the side attachment points CD, CG, preferably above the battery B1 or B2. This is implemented through the vertical extension EP.
Par ailleurs, les points de fixation CD, CG, et PS sont disposés à deux hauteurs de fixation H1 , H2 sur le châssis C et sur la patte de fixation P. En d’autres termes, il y a deux points de fixation pour chacune des structures de fixation SD, SG, SS. Les points de fixation CD, CG, PS sont de préférence au niveau de la face arrière de la batterie B1 ou B2. Furthermore, the fixing points CD, CG, and PS are arranged at two fixing heights H1, H2 on the frame C and on the fixing lug P. In other words, there are two fixing points for each SD, SG, SS attachment structures. The attachment points CD, CG, PS are preferably at the level of the rear face of the battery B1 or B2.
