The invention also relates to a battery module comprising such a system and to a vehicle, in particular a motor vehicle, provided with this system.
Une batterie de traction est composée d'un ensemble de modules appelés modules de batterie. Le raccordement et le débranchement des modules entre eux est une opération est délicate et dangereuse pour l'utilisateur au regard des risques de court-circuit, de chocs électriques et d'électrocutions pouvant être engendrés tant par la mise à nue des bornes, que par la proximité des bornes positive et négative. A traction battery consists of a set of modules called battery modules. The connection and disconnection of the modules between them is an operation which is delicate and dangerous for the user with regard to the risks of short-circuiting, electric shocks and electrocutions which can be generated both by the laying bare of the terminals, by the proximity of the positive and negative terminals.
Or les risques précités doivent être impérativement évités, notamment au cours de la phase de montage en usine. However, the aforementioned risks must be avoided, especially during the factory assembly phase.
Les seules protections connues sont des protections individuelles telles que des outils réalisés en matériaux isolants, des gants, des visières et des protections internes au module de batterie tels que des soupapes ou des systèmes de désoperculassions. The only known protections are individual protections such as tools made of insulating materials, gloves, visors and protections internal to the battery module such as valves or uncapping systems.
Le maniement de chaque module et les connexions réalisées entre les modules doivent être ainsi réalisées de façon sécurisée, mais également pendant un temps de manipulation relativement rapide. The handling of each module and the connections made between the modules must thus be made in a secure manner, but also during a relatively fast handling time.
Dans ce contexte, la présente invention vise un système de contrôle de l'accès des bornes positive et négative d'un module de batterie qui permet la connexion et le débranchement des modules entre eux de façon sécurisée et rapide. In this context, the present invention aims at a system for controlling the access of the positive and negative terminals of a battery module which allows the connection and disconnection of the modules between them in a secure and fast manner.
A cet effet, le système de l'invention permet de contrôler l'accès des bornes positive et négative d'un module de batterie comportant un premier et un second caches de protection respectivement des bornes positive et négative. Ce système est essentiellement caractérisé en ce que les premier et second caches de protection sont aptes à se déplacer en découvrant la borne associée et en ce qu'il comprend :
- des moyens de blocage empêchant un tel déplacement tant qu'une pièce de libération solidaire du premier ou du second cache de protection n'est pas située en regard d'un orifice réalisé sur une pièce de blocage montée dans le module de batterie, et For this purpose, the system of the invention makes it possible to control the access of the positive and negative terminals of a battery module comprising a first and a second protective cover respectively of the positive and negative terminals. This system is essentially characterized in that the first and second protective covers are able to move by discovering the associated terminal and in that it comprises: blocking means preventing such displacement as long as a release piece integral with the first or the second protective cover is not situated opposite an orifice made on a locking piece mounted in the battery module, and
- des moyens de déblocage comprenant une pièce d'entraînement dont la course provoque le déplacement soit de la pièce de libération relativement à la pièce de blocage, soit de la pièce de blocage relativement à la pièce de libération, jusqu'à ce que l'orifice de la pièce de blocage soit situé en regard de la pièce de libération, autorisant ainsi le dit cache de protection concerné à se déplacer en découvrant la borne associée. - Release means comprising a drive member whose stroke causes the displacement of either the release member relative to the locking member or the locking member relative to the release member, until the orifice of the blocking piece is located opposite the release part, thus allowing said protective cover concerned to move by discovering the associated terminal.

La pièce d'entraînement 10 présente une forme tronconique dont le bord 12 situé vers la borne positive 3 est incliné par rapport à l'axe XX' de déplacement du premier cache de protection 5, de sorte que la largeur I de l'extrémité inférieure 13 de la pièce d'entraînement 10 au niveau de la pièce de blocage 7 est inférieure à la largeur L de jonction avec le premier cache de protection 5. The driving part 10 has a frustoconical shape whose edge 12 located towards the positive terminal 3 is inclined relative to the axis XX 'of displacement of the first protective cover 5, so that the width I of the lower end 13 of the driving part 10 at the blocking piece 7 is smaller than the width L of junction with the first protective cover 5.
Dans la position représentée sur la figure 1 , l'extrémité inférieure 13 de la pièce d'entraînement 10 est prise en sandwich entre la paroi latérale 14 du module 1 et un second bord latéral 15 de la pièce de blocage 7 qui est situé à l'opposée du premier bord latéral 9 de cette pièce de blocage 7 au niveau de laquelle est monté le ressort 8. In the position shown in Figure 1, the lower end 13 of the driving part 10 is sandwiched between the side wall 14 of the module 1 and a second side edge 15 of the locking piece 7 which is located at opposed to the first lateral edge 9 of this locking piece 7 at which the spring 8 is mounted.
La force de rappel de ce ressort 8 pousse la pièce de blocage 7 vers la pièce d'entraînement 10 selon un axe YY' perpendiculaire à l'axe XX' de déplacement du premier cache de protection 5. The restoring force of this spring 8 pushes the locking piece 7 towards the driving piece 10 along an axis YY 'perpendicular to the axis XX' of movement of the first protective cap 5.
Par ailleurs, la pièce de blocage 7 comporte un orifice traversant 16 dont la forme coïncide avec une pièce de libération 17 qui est solidaire du second cache de protection 6 en s'étendant depuis la face inférieure 18 de ce second cache de protection 6 jusqu'à proximité de la pièce de blocage 7. Furthermore, the locking piece 7 has a through hole 16 whose shape coincides with a release piece 17 which is integral with the second protective cover 6 extending from the lower face 18 of the second protective cover 6 until near the locking piece 7.
Sur la figure 1 , l'extrémité 19 de la pièce de libération 17 n'est pas en regard de l'orifice 16 de la pièce de blocage 7, de sorte que dans cette position, le
second cache de protection 6 ne peut pas être abaissé pour donner accès à la borne positive 3. In FIG. 1, the end 19 of the release piece 17 is not facing the orifice 16 of the locking piece 7, so that in this position the second protective cover 6 can not be lowered to give access to the positive terminal 3.
Pour assurer une sécurité totale du système, l'extrémité 19 de la pièce de libération 17 est suffisamment proche de la pièce de blocage 7 pour empêcher l'abaissement du second cache de protection 6, mais permet néanmoins le déplacement de la pièce de blocage 7 selon l'axe YY' comme illustré sur les figures 2 et 3. To ensure total safety of the system, the end 19 of the release member 17 is sufficiently close to the locking piece 7 to prevent the lowering of the second protective cover 6, but nevertheless allows the displacement of the locking piece 7 along the axis YY 'as illustrated in FIGS. 2 and 3.
En référence à la figure 2, lorsque l'opérateur souhaite accéder aux bornes négatives 2 et positive 3, il appuie en premier lieu sur le premier cache de protection 5 soit manuellement, soit à l'aide d'un premier connecteur 20 permettant de relier électriquement la borne négative 20 à un module adjacent ou à un appareil électrique externe. Le premier connecteur 20 comporte un évidemment non visible correspondant à la forme de la borne négative 2 et lui permettant d'assurer le contact électrique avec cette borne négative 2. With reference to FIG. 2, when the operator wishes to access the negative 2 and positive 3 terminals, he firstly presses on the first protective cover 5 either manually or with a first connector 20 making it possible to connect electrically the negative terminal 20 to an adjacent module or to an external electrical device. The first connector 20 comprises a non-visible recess corresponding to the shape of the negative terminal 2 and allowing it to ensure electrical contact with this negative terminal 2.
L'abaissement du premier cache de protection 5 entraîne le déplacement de la pièce d'entraînement 10 selon la flèche A, lequel déplacement entraîne de façon concomitante le décalage de la pièce de blocage 7 vers le ressort 8 selon la flèche B par glissement de l'extrémité 15 de la pièce de blocage 7 le long du bord incliné 12 de la pièce d'entraînement 10. The lowering of the first protective cover 5 causes the displacement of the driving part 10 according to the arrow A, which displacement concomitantly causes the offset of the locking piece 7 towards the spring 8 according to the arrow B by sliding of the end 15 of the locking piece 7 along the inclined edge 12 of the driving piece 10.
L'effort exercé par la pièce d'entraînement 10 sur la pièce de blocage 7 s'oppose à la force de rappel du ressort 8. The force exerted by the driving part 10 on the locking piece 7 opposes the restoring force of the spring 8.
L'orifice 16 se décale ainsi, avec la pièce de blocage 7, en direction du ressort 8, jusqu'à se trouver en regard de la pièce d'entraînement 10 (figure 3). The orifice 16 thus shifts, with the locking piece 7, in the direction of the spring 8, until facing the driving piece 10 (Figure 3).
Dans cette dernière position, le premier cache de protection est totalement abaissé et le premier connecteur 20 est alors en place sur la borne négative 2. In this latter position, the first protective cover is completely lowered and the first connector 20 is then in place on the negative terminal 2.
Il est alors possible d'abaisser le second cache de protection 6 qui entraîne le déplacement selon la flèche C (figure 4) de la pièce de libération 17, qui traverse alors la pièce de blocage 7 par l'orifice 16. It is then possible to lower the second protective cover 6 which causes the displacement along the arrow C (Figure 4) of the release member 17, which then passes through the locking piece 7 through the orifice 16.
En position finale, comme illustré sur la figure 5, un second connecteur 21 est en place sur le second cache de protection 6, les bornes négative 2 et positive 3 sont alors reliées à un module adjacent ou à un appareil électrique externe. In the final position, as illustrated in FIG. 5, a second connector 21 is in place on the second protective cover 6, the negative 2 and positive 3 terminals are then connected to an adjacent module or to an external electrical device.
Le système de l'invention permet ainsi d'empêcher l'abaissement du second cache de protection 6 et donc la mise à nue de la borne positive 3 tant que le premier cache de protection 5 n'est pas totalement abaissé.
Les deux caches de protection ne peuvent ainsi pas être abaissés dans le même temps, il est nécessaire d'opérer d'abord en abaissant le premier cache de protection 5 puis le second cache de protection 6. The system of the invention thus makes it possible to prevent the lowering of the second protective cover 6 and thus the exposure of the positive terminal 3 as long as the first protective cover 5 is not completely lowered. The two protective covers can not be lowered at the same time, it is necessary to operate first by lowering the first protective cover 5 and the second protective cover 6.
A l'inverse, on comprend que pour retirer les premier 20 et second 21 connecteurs, il faudra également opérer en deux temps soit en premier lieu faire remonter le second cache de protection 6 puis le premier cache de protection 5. En effet, si on remonte le premier cache de protection 5 soit en premier lieu, soit en même temps que le second cache de protection 6, la pièce de libération 17 restera bloquée dans l'orifice 16 puisque la force de rappel du ressort 8 provoquera la poussée de la pièce de blocage 7 vers la paroi latérale 14 du module 1 . On the contrary, it is understood that to remove the first 20 and second 21 connectors, it will also operate in two stages is first to raise the second protective cover 6 and the first protective cover 5. Indeed, if it raises the first protective cover 5 either first or at the same time as the second protective cover 6, the release piece 17 will remain locked in the orifice 16 since the restoring force of the spring 8 will cause the thrust of the piece 7 to the side wall 14 of the module 1.
En outre, la sécurité du système de l'invention est renforcée par la présence d'une paroi de séparation 22 solidaire du module 1 et s'étendant entre les premier 5 et second 6 caches de protection (figures 4 et 5) de façon à éviter tout contact électrique entre les premier 5 et second 6 caches de protection. In addition, the safety of the system of the invention is reinforced by the presence of a partition wall 22 integral with the module 1 and extending between the first 5 and second 6 protective covers (Figures 4 and 5) so as to avoid any electrical contact between the first 5 and second 6 protective covers.
En référence aux figures 6 et 7, le système de l'invention peut également permettre d'éviter la mise à nue d'une borne 2a par abaissement du cache de protection associé 5a, ce qui représente un danger pour l'opérateur. With reference to FIGS. 6 and 7, the system of the invention can also make it possible to prevent the laying down of a terminal 2a by lowering the associated protective cover 5a, which represents a danger for the operator.
Le système de l'invention peut ainsi être adapté pour que l'abaissement du premier cache de protection 5a ne puisse s'effectuer que lorsque le connecteur correspondant 20a est en place sur le premier cache de protection 5a. The system of the invention can thus be adapted so that the lowering of the first protective cover 5a can be performed only when the corresponding connector 20a is in place on the first protective cover 5a.
Pour ce faire, la pièce de blocage 7a est montée fixe dans le module 1 a par des moyens non représentés. Cette pièce de blocage 7a comporte un orifice traversant 16a de forme adaptée à la pièce de libération 17a qui est ici montée à translation dans le premier cache de protection 5a. To do this, the locking piece 7a is fixedly mounted in the module 1a by means not shown. This locking piece 7a has a through hole 16a of shape adapted to the release member 17a which is here mounted in translation in the first protective cover 5a.
Plus précisément, la pièce de libération 17a est inclinée dans le premier cache de protection 5a en s'étendant depuis son extrémité supérieure 25a au niveau de la face supérieur 26a du premier cache de protection 5a jusqu'à son extrémité inférieure 31 a à proximité de la pièce de blocage 7a. More specifically, the release member 17a is inclined in the first protective cover 5a extending from its upper end 25a at the upper face 26a of the first protective cover 5a to its lower end 31a near the the locking piece 7a.
Un logement non visible est prévu dans le premier cache de protection 5a pour accueillir la partie de la pièce de libération 17a située dans le premier cache de protection 5a ainsi qu'un ressort 8a qui assure la mobilité de la pièce de translation 17a et qui s'étend entre la face interne arrière 27a du dit logement et la pièce de libération 17a.
La force de rappel du ressort 8a pousse la pièce de libération 17a vers l'avant du premier cache de protection 5a. A non-visible housing is provided in the first protective cover 5a to accommodate the part of the release member 17a located in the first protective cover 5a and a spring 8a which ensures the mobility of the translation member 17a and which s extends between the rear inner face 27a of said housing and the release piece 17a. The restoring force of the spring 8a pushes the release piece 17a towards the front of the first protective cover 5a.
Ce système prévoit également une pièce d'entraînement 10a qui est solidaire du premier connecteur 20a en s'étendant depuis la face inférieure 28a de ce premier connecteur 20a. This system also provides a driving part 10a which is secured to the first connector 20a extending from the lower face 28a of the first connector 20a.
La pièce d'entraînement 10a présente une forme triangulaire avec un bord incliné 30a dont l'inclinaison est disposée dans le même sens que l'inclinaison de la pièce de libération 17a. The driving piece 10a has a triangular shape with an inclined edge 30a whose inclination is arranged in the same direction as the inclination of the release piece 17a.
Tant que le connecteur 20a n'est pas en place sur le premier cache de protection, c'est-à-dire tant que le connecteur est dans la position illustrée sur la figure 1 , l'extrémité inférieure 31 a de la pièce de libération 17a n'est pas en regard de l'orifice 16a de la pièce de blocage 7a, ce dont il résulte que le premier cache de protection 5a ne peut pas être abaissé en donnant accès à la borne négative 2a. As long as the connector 20a is not in place on the first protective cover, that is to say as long as the connector is in the position shown in FIG. 1, the lower end 31a of the release piece 17a is not opposite the opening 16a of the locking piece 7a, which results that the first protective cover 5a can not be lowered by giving access to the negative terminal 2a.
Pour abaisser le premier cache de protection 5a, le premier connecteur 20a doit d'abord être positionné au dessus du premier cache de protection 5a de façon que l'extrémité 32a de la pièce d'entraînement 10a soit situé à proximité de l'extrémité supérieure 25a de la pièce de libération 17a en étant sensiblement décalé vers l'avant du premier cache de protection 5a. To lower the first protective cover 5a, the first connector 20a must first be positioned above the first protective cover 5a so that the end 32a of the drive part 10a is located near the upper end. 25a of the release member 17a being substantially offset towards the front of the first protective cover 5a.
L'opérateur exerce alors un effort de poussée sur le connecteur 20a vers le premier cache de protection selon la flèche D (figure 6) jusqu'à ce qu'il y ait contact surfacique du connecteur 20a sur le premier cache de protection 5a, ce qui provoque l'introduction de la pièce d'entraînement 10a dans le premier 20a connecteur, et ce qui engendre de façon concomitante le décalage de la pièce de libération 17a selon la flèche E vers l'arrière du premier cache de protection 5a en allant à encontre de la force de rappel du ressort 8a. The operator then exerts a thrust force on the connector 20a towards the first protective cover according to the arrow D (FIG. 6) until there is surface contact of the connector 20a on the first protective cover 5a, which which causes the introduction of the driving part 10a in the first 20a connector, and which concomitantly generates the offset of the release piece 17a according to the arrow E towards the rear of the first protective cover 5a by going to against the return force of the spring 8a.
Ce décalage de la pièce de libération 17a est rendu possible par le glissement de l'extrémité supérieure 25a de cette pièce de libération 17a le long du plan incliné 30a de la pièce d'entraînement 10a. This offset of the release member 17a is made possible by the sliding of the upper end 25a of this release member 17a along the inclined plane 30a of the drive part 10a.
Une fois que le premier connecteur 20a est en contact surfacique avec le premier cache de protection 5a, l'extrémité inférieure 31 a de la pièce de libération 17a se trouve en regard de l'orifice 16a de la pièce de blocage 7a, ce qui autorise l'abaissement du premier cache de protection 5a selon la flèche F de la figure 8.
Ce dernier système permet donc d'éviter que le premier cache de protection 5a ne puisse être abaissé sans que le premier connecteur 20a ne soit en place sur ce premier cache de protection 5a. Ce système s'applique également au second cache de protection et à la borne positive correspondante qui ne sont pas représentés sur les figures 6 à 8. Once the first connector 20a is in surface contact with the first protective cover 5a, the lower end 31a of the release piece 17a is opposite the opening 16a of the locking piece 7a, which allows lowering the first protective cover 5a according to the arrow F of FIG. 8. The latter system thus makes it possible to prevent the first protective cover 5a from being lowered without the first connector 20a being in place on this first protective cover 5a. This system also applies to the second protective cover and the corresponding positive terminal which are not shown in FIGS. 6 to 8.
Il est possible de prévoir un module de batterie comportant uniquement le système de l'invention de la première variante des figures 1 à 5 ou uniquement le système de l'invention de la seconde variante des figures 6 à 8. It is possible to provide a battery module comprising only the system of the invention of the first variant of FIGS. 1 to 5 or only the system of the invention of the second variant of FIGS. 6 to 8.
De préférence, le module de batterie 1 ,1 a comportera les deux systèmes de contrôle de l'invention de façon à assurer une protection optimum à l'opérateur concernant l'accès aux bornes négative et positive du module, c'est-à-dire en autorisant l'abaissement d'un cache de protection uniquement d'une part lorsque l'autre cache de protection a été préalablement totalement abaissé, et d'autre part lorsque le connecteur associé est bien en place sur le cache de protection considéré. Preferably, the battery module 1, 1a will comprise the two control systems of the invention so as to provide optimum protection to the operator concerning access to the negative and positive terminals of the module, ie say by allowing the lowering of a protective cover only on the one hand when the other protective cover has been previously fully lowered, and secondly when the associated connector is in place on the protective cover considered.
Les risques de court circuit, d'électrocutions et de chocs électriques sont ainsi fortement diminués.
The risks of short circuit, electrocution and electric shock are greatly reduced.
