Description

Dispositif d 'alimentation électrique du type batterie Battery type power supply device
La présente invention a pour objet un dispositif d'alimentation électrique du type battene constitué d'un socle sur lequel repose un bac, ledit bac étant muni en sous face de connexions électriques disposées en regard des connexions électriques du socle, ledit socle et ledit bac comportant en outre des moyens complémentaires de connexion mécanique.The present invention relates to an electrical supply device of the battene type consisting of a base on which a tank rests, said tank being provided on the underside with electrical connections arranged opposite the electrical connections of the base, said base and said tank. further comprising additional mechanical connection means.
La présente invention concerne particulièrement la batterie du type décrit dans les demandes FR 2 662 121 - FR 2 715 764 et FR 2 743 668 du même demandeur.The present invention relates particularly to the battery of the type described in applications FR 2 662 121 - FR 2 715 764 and FR 2 743 668 from the same applicant.
De manière générale, les accidents de la circulation à l'origine d'incendies sont particulièrement meurtriers, lesdits incendies transformant souvent les véhicules en véritables fournaises. Ces incendies, qui sont des facteurs aggravants dans les accidents, ont souvent une origine électπque.In general, traffic accidents causing fires are particularly deadly, said fires often transforming vehicles into real furnaces. These fires, which are aggravating factors in accidents, often have an electrical origin.
Il s'est donc développé un certain nombre de systèmes qui permettent de couper automatiquement le circuit électπque des véhicules automobiles lors d'un accident sous l' effet d' un choc engendré par celui-ci.A number of systems have therefore been developed which make it possible to automatically cut the electrical circuit of motor vehicles during an accident under the effect of a shock generated by it.
On peut par exemple citer le document FR 2 340 219 dans lequel est décπt un appareil de sécurité pour véhicules automobiles réalisant une coupure électπque par l' intermédiaire d' un bras oscillant.Mention may be made, for example, of the document FR 2 340 219 in which a safety device for motor vehicles is produced, carrying out an electrical cut-off by means of a swinging arm.
De la même manière, le document FR 2 318 496 se rapporte à un coupe - circuit à fonctionnement automatique dans lequel un élément est susceptible de se déplacer entre une position où le contact est établi entre deux bornes et une position où le contact est supprimé.Likewise, document FR 2 318 496 relates to an automatic operating circuit breaker in which an element is capable of moving between a position where contact is established between two terminals and a position where contact is removed.
Le dispositif du document FR 2 616 958 repose quant à lui sur un accéléro- contact déclenchant la mise en fonction d'un inflammateur pyrotechnique agissant au moyen de gaz sur une enveloppe de verrouillage et un fourreau isolant qui s' interpose entre une borne mobile et une borne de batterie.The device of document FR 2 616 958 is based on an accelerator contact triggering the activation of a pyrotechnic igniter acting by means of gas on a locking envelope and an insulating sheath which is interposed between a movable terminal and a battery terminal.
On peut également citer le document FR 2 677 310 qui divulgue un mécanisme reposant sur un ensemble complexe de tπngles, pistons et câblesMention may also be made of document FR 2 677 310 which discloses a mechanism based on a complex set of pins, pistons and cables
Tous les systèmes connus à ce jour sont complexes et donc souvent d'une réalisation onéreuseAll the systems known to date are complex and therefore often costly to produce
Pour remédier à ces inconvénients de l'art antérieur, le demandeur a déjà proposé dans le document FR 2 715 764 un procédé et un dispositif de mise hors circuit simples et faciles à mettre en oeuvre.To remedy these drawbacks of the prior art, the applicant has already proposed in document FR 2 715 764 a method and a device for switching off simple and easy to implement.
Toutef ois, on a constaté de manière empirique, malgré une mise hors circuit, l'existence de micro-coupures préjudiciables aux dispositifs électriques embarqués dans un \ éhicule et surtout d'un arc électπque susceptible de provoquer une inflammation du carburant lors d' un accident.However, it has been empirically observed, in spite of being switched off, the existence of micro-cuts which are detrimental to the electrical devices on board a vehicle and above all an electric arc capable of causing fuel ignition during a accident.
Le but de l' invention est de pallier les inconvénients de l'art antérieur Un autre but de l' ιn\ entιon est de proposer un dispositif d'alimentation facile à utiliser, à remettre en fonction après un éventuel choc et à rechargerThe object of the invention is to overcome the drawbacks of the prior art. Another object of the invention is to provide an easy-to-use supply device, to be put back into operation after a possible shock and to be recharged.
Conformément à l' invention, ce résultat est obtenu a\ ec un dispositif d'alimentation électπque du type batteπe comprenant un socle sur lequel repose un bac, ledit bac étant muni en sous face de connexions électriques en regard des connexions électriques du socle, ledit socle et ledit bac comportant également des moyens complémentaires de connexions mécaniques, caractérisé en ce que le socle comporte un logement muni d' un couvercle amovible et dans le tond duquel débouche à plat deux liaisons métalliques diamétralement opposées et faisant partie du circuit électπque extérieur de la batterie, l'extrémité frontale desdites liaisons délimitant entre-elles un espacement, lesdites liaisons étant maintenues en contact électrique au moyen d' un plot cyhndπque de liaison posé en appui sur elles au niveau de l'espacement, une masselotte maintenant en position ledit plot par gravité, ladite masselotte comportant en outre un moyen permettant son mouvement en cas de choc sur le véhicule, ledit mouvement libérant le plot cyhndπque de sa position de contact entre les liaisons métalliques pour que le circuit électrique soit ouvert.According to the invention, this result is obtained with an electric power supply device of the batteπe type comprising a base on which a tank rests, said tank being provided on the underside with electrical connections opposite the electrical connections of the base, said base and said tank also comprising complementary mechanical connection means, characterized in that the base comprises a housing provided with a removable cover and in the mound of which opens out flat two diametrically opposite metal connections forming part of the external electrical circuit of the battery, the front end of said links delimiting a spacing therebetween, said links being maintained in electrical contact by means of a cyhndπque connecting pad placed resting on them at the spacing, a counterweight keeping said pad in position by gravity, said flyweight further comprising means allowing its movement in the event of impact on the vehicle, said movement releasing the cyhndπque stud from its contact position between the metal links so that the electrical circuit is open.
De manière préférentielle, ledit moyen permettant l'éjection consiste en un ressort disposé verticalement dans un trou débouchant situé au centre de la masselotte, ladite masselotte étant munie d'un évidement central communiquant avec ledit trou et permettant de recevoir le plot cylindrique, ledit ressort étant compπmé en appui inféπeur sur ledit plot cylindrique et étant surmonté d'une bille dont la course vers le haut est limitée par le cou\ ercle du logement.Preferably, said means allowing the ejection consists of a spring arranged vertically in a through hole located in the center of the counterweight, said counterweight being provided with a central recess communicating with said hole and making it possible to receive the cylindrical stud, said spring being compressed in lower support on said cylindrical stud and being surmounted by a ball whose stroke upwards is limited by the neck of the housing.
En outre, la masselotte comporte une pai tie isolante sensiblement en forme de semelle, comportant ledit évidement central sensiblement de forme complémentaire audit plot cylindrique et destiné à le recevoir, ledit évidement étant prolongé en partie supéπeure par ledit trou débouchant, au moins une rondelle étant empilée sur ladite partie en matériau isolant.In addition, the counterweight comprises an insulating part substantially in the form of a sole, comprising said central recess substantially of complementary shape to said cylindrical stud and intended to receive it, said recess being extended in the upper part by said through hole, at least one washer being stacked on said part of insulating material.
En cas d'accident, le choc engendré par celui-ci provoque un mouvement de translation de la masselotte dans le boîtier, obligeant la bille qui assure le maintien de la masselotte à compresser le ressort. La masselotte est alors déplacée jusqu'à ce que la bille se bloque dans la rainure circulaire réalisée a cet effet en face inféπeure du couvercle du logement.In the event of an accident, the shock generated by this causes a translational movement of the counterweight in the housing, forcing the ball which ensures the maintenance of the counterweight to compress the spring. The counterweight is then moved until the ball locks in the circular groove made for this purpose opposite the bottom of the housing cover.
Dans son mouvement, la masselotte déplace le plot de liaison, provoquant au final l' ouverture du circuit électπqueIn its movement, the flyweight moves the connection pad, ultimately causing the opening of the electrical circuit.

Pour une compréhension plus aisée de l' invention, on prendra comme exemple de dispositif d'alimentation une batteπe de véhicule. H faut noter que le terme bac est généralement utilisé par l' homme de métier avant la mise en place des éléments constitutifs internes de la batterie Une fois cette mise en place effectuée et la fermeture du bac par un couvercle, le terme batterie se substitue au terme bac dans la terminologie de l'homme de métier On se référera tout d'abord à la figure 1. Une batterie ( 1) selon l' invention se compose d' un bac (2) en matériau isolant supporté par un socle (3) en matéπau isolant, par exemple en pol\ propylène Le bac (2) est surmonté d'un couvercle (4).For an easier understanding of the invention, a vehicle batteπe will be taken as an example of a power supply device. It should be noted that the term bin is generally used by a person skilled in the art before the installation of the internal constitutive elements of the battery. Once this installation has been carried out and the closure of the bin with a cover, the term battery replaces the term bin in the terminology of those skilled in the art We will first refer to Figure 1. A battery (1) according to the invention consists of a tank (2) of insulating material supported by a base (3 ) in insulating material, for example in pol \ propylene The tank (2) is surmounted by a cover (4).
En se référant aux figures 2 et 7, le bac (2) comporte des compartiments (5) dans lesquels sont disposés les plaques de polaπté différente en plomb constituant la batterieReferring to Figures 2 and 7, the tank (2) has compartments (5) in which are arranged the different polarity plates of lead constituting the battery
Le circuit électrique extéπeur du bac est assuré en partie par deux lamelles (7) moulées dans les parois latérales du bac (2) et que l'on explicitera ultéπeurementThe external electrical circuit of the tank is provided in part by two strips (7) molded in the side walls of the tank (2) and which will be explained later
La face supérieure (3a) du socle (3) et la sous face (2a) du bac (2) sont de forme complémentaire, par exemple en U, permettant une bonne stabilité et un positionnement correct du bac (2) sur le socle (3). Ainsi, le socle (2) présente en partie centrale (3) une surépaisseur, une zone de distribution (49) et des dégagements (9) en coin.The upper face (3a) of the base (3) and the underside (2a) of the container (2) are of complementary shape, for example in a U shape, allowing good stability and correct positioning of the container (2) on the base ( 3). Thus, the base (2) has in the central part (3) an additional thickness, a distribution area (49) and recesses (9) in the corner.
Le socle (2) comporte un logement (10) sous la forme d' un évidement circulaire ( 11) si le socle est réalisé par moulage (13) (voir figure 3) ou d'un boîtier circulaire si le socle est réalisé par extrusion ( 14) (voir figure 4).The base (2) comprises a housing (10) in the form of a circular recess (11) if the base is produced by molding (13) (see FIG. 3) or of a housing circular if the base is produced by extrusion (14) (see Figure 4).
Dans le fond du logement débouchent de manière diamétralement opposées, deux liaisons ( 15, 16) en cuivre, laiton ou toute autre matériau conducteur habituellement utilisé par l'homme de l'art, lesdites liaisons ( 15,16) réalisant en partie le circuit électrique du socle (2). L'extrémité frontale ( 15a, 16a) desdites liaisons (15,16) définissant un espacement (6) sensiblement en partie centrale du logement (10), ledit espace réalisant une discontinuité dans le circuit électrique extérieur de la batteπe.In the bottom of the housing open diametrically opposite, two connections (15, 16) made of copper, brass or any other conductive material usually used by those skilled in the art, said connections (15, 16) partially carrying out the circuit electrical base (2). The front end (15a, 16a) of said links (15,16) defining a spacing (6) substantially in the central part of the housing (10), said space producing a discontinuity in the external electrical circuit of the batteπe.
Un plot cylindrique de liaison ( 17) en matériau conducteur électrique, par exemple en laiton, de préférence en cuivre, est posé en appui sur les deux lamelles ( 15, 16) permettant ainsi de maintenir le contact électrique entre lesdites lamelles.A cylindrical connection pad (17) made of electrically conductive material, for example brass, preferably copper, is placed in abutment on the two lamellae (15, 16), thus making it possible to maintain the electrical contact between said lamellae.
Le plot ( 17) est surmonté d' une masselotte ( 18) comportant une partie isolante (47) munie d' un évidement central (43) sensiblement de forme complémentaire audit plot et prolongé en partie supéπeure par un trou débouchant (44) dans lequel est disposé verticalement un ressort ( 19) dont l'extrémité inféπeureThe stud (17) is surmounted by a counterweight (18) comprising an insulating part (47) provided with a central recess (43) substantially of complementary shape to said stud and extended in the upper part by a through hole (44) in which a spring (19) is arranged vertically, the lower end of which
( 19a) est en appui sur la face supérieure du plot et l'extrémité supérieure (19b) est surmontée d'une bille (21), par exemple en acier dont la course vers le haut est limitée par un couvercle cylindrique amovible (20), en matériau isolant, dont est muni le logement (10). Sur ladite partie isolante (47) est positionnée une rondelle (48) de masse importante réalisée dans un matériau lourd, par exemple en plomb.(19a) is supported on the upper face of the stud and the upper end (19b) is surmounted by a ball (21), for example made of steel whose upward stroke is limited by a removable cylindrical cover (20) , of insulating material, which is provided with the housing (10). On said insulating part (47) is positioned a washer (48) of large mass made of a heavy material, for example lead.
La fixation de ce couvercle (20) au logement se fait par un système baïonnette. Ainsi la tranche du couvercle comporte un ou plusieurs ergots (22), par exemple trois, disposés en étoile comme illustré à la figure 14, aptes à venir s'engager par rotation axiale du couvercle dans des crans (23) prévus à cet effet dans la paroi de la cavité ( 1 1) du socle moulé ( 13) ou du boîtier ( 12) du socle extrudé ( 14).The fixing of this cover (20) to the housing is done by a bayonet system. Thus the edge of the cover has one or more lugs (22), for example three, arranged in a star as illustrated in FIG. 14, capable of coming to engage by axial rotation of the cover in notches (23) provided for this purpose in the wall of the cavity (1 1) of the molded base (13) or of the housing (12) of the extruded base (14).
Le couvercle (20) comprend en outre en face inféπeure un évidement central (46) et une rainure circulaire (8) concentrique audit évidement.The cover (20) further comprises on the lower face a central recess (46) and a circular groove (8) concentric with said recess.
Le ressort (19) comprimé entre la bille (21) et le plot (17) tend à pousser vers le haut la bille, la course verticale de la bille (21 ) étant limitée par le couvercle (20) en position normale d' utilisation, ladite bille (21) étant alors positionnée dans F évidement central (46)The spring (19) compressed between the ball (21) and the stud (17) tends to push up the ball, the vertical stroke of the ball (21) being limited by the cover (20) in the normal position of use, said ball (21) then being positioned in the central recess (46)
En cas de choc du véhicule, dans n'importe quelle direction, le mouvement de la masselotte ( 18) fait que la bille (21) quitte l'évidement central (46) et comprime le ressort ( 19). La masselotte ( 18) n'est plus maintenue en position centrale et se déplace jusqu'à ce que la bille (21), sous l'effet du ressort, se positionne dans la rainure circulaire (8), entraîne le plot ( 17) qui, au final après le choc, n'assure plus le contact électπque entre les deux liaisons ( 15, 16). La masselotte et le plot associés jouent ainsi le rôle de coupe-circuit ou de système de mise hors circuit de la batteπe.In the event of an impact from the vehicle, in any direction, the movement of the counterweight (18) causes the ball (21) to leave the central recess (46) and compress the spring (19). The counterweight (18) is no longer held in the central position and moves until the ball (21), under the effect of the spring, is positioned in the circular groove (8), drives the stud (17) which, in the end after the impact, no longer ensures electrical contact between the two connections (15, 16). The counterweight and the associated stud thus play the role of circuit breaker or system for switching off the batteπe.
Pour remettre la batteπe en fonction, l'utilisateur enlève le couvercle et repositionne simplement l'ensemble masselotte / plot et la bille dans la position initiale de contact entre les deux liaisons, la compression du ressort étant assurée par la pression du couv ercle (20) sur la bille, celle-ci étant alors repositionnée dans l'évidement central (46)To restore the batteπe function, the user removes the cover and simply reposition the balance / pad assembly and the ball in the initial position of contact between the two connections, the compression of the spring being ensured by the pressure of the cover (20 ) on the ball, the latter then being repositioned in the central recess (46)
De manière a\ antageuse, le couvercle (20) peut présenter en face inférieure des rainures (45) dont l'intersection constitue F évidement central (46)Antagonously, the cover (20) may have grooves (45) on the lower face, the intersection of which constitutes a central recess (46).
En se référant à la figure 3, le socle peut être moulé. Les deux liaisons ( 15, 16) sont alors moulées dans le corps du socle. En référence à la figure 4, le socle peut être également extrudé. Il est alors creux et comporte une cavité centrale protégée par un cache avant (24) (voir figure 5a), un cache arrière (25) (voir figure 5b) et un couvercle (26) (voir figure 6), F ensemble étant maintenu par emboîtement.Referring to Figure 3, the base can be molded. The two connections (15, 16) are then molded into the body of the base. Referring to Figure 4, the base can also be extruded. It is then hollow and has a central cavity protected by a front cover (24) (see Figure 5a), a rear cover (25) (see Figure 5b) and a cover (26) (see Figure 6), F together being held by nesting.
Comme on peut le voir aux figures 8 et 9, les lamelles (7) comportent une partie inféπeure (27) en forme de L réalisée en cuivre et en partie supéπeure (28) réalisée en plomb, ladite partie supéπeure surmoulant l'extrémité supéπeure de la partie en cuι\ re (27) Ce mode de liaison entre les parties en cuivre et en plomb évite la corrosion du plomb par l'acide sulfuπque de la batterie et donc les dépôts de sulfates de plomb nuisible au fonctionnement de la batterie. Lesdites lamelles (7) permettent les liaisons électriques entre les plaques négatives et positives vers les 7As can be seen in Figures 8 and 9, the lamellae (7) have an L-shaped lower part (27) made of copper and upper part (28) made of lead, said upper part overmolding the upper end of the cupped part (27) This mode of connection between the copper and lead parts avoids lead corrosion by the sulfuπque acid in the battery and therefore deposits of lead sulfates detrimental to the operation of the battery. Said strips (7) allow the electrical connections between the negative and positive plates to the 7
connexions électriques du socle.electrical connections of the base.
Les connexions électriques du socle consistent en deux bornes mâles (29,30) sous forme de plots de section hexagonale et les connexions électrique du bac consistent en deux bornes femelles (non représentées) de forme complémentaire auxdites bornes mâles.The electrical connections of the base consist of two male terminals (29,30) in the form of studs of hexagonal section and the electrical connections of the tray consist of two female terminals (not shown) of complementary shape to said male terminals.
De manière préférentielle, lesdites plots (29,30) comportent en péπphéπe des joints toπques (31) permettant une étanchéité des connexions électπques.Preferably, said studs (29,30) comprise peπphéπe toπques seals (31) allowing sealing of electrical connections.
De manière préférentielle, le bac (2) comporte deux accès latéraux (32,33) aux lamelles (7) pour permettre le positionnement des bornes (34) et un chargeur, lesdites bornes (34) consistant de manière préf érentielle en des lamelles à coins arrondis (35) (voir figure 15) à section transv ersale légèrement courbée. De cette façon, les lamelles "s'auto-bloquent" dans les accès latéraux (32,33).Preferably, the tank (2) has two lateral accesses (32,33) to the strips (7) to allow the positioning of the terminals (34) and a charger, said terminals (34) preferably consisting of strips with rounded corners (35) (see Figure 15) with slightly curved transverse section. In this way, the slats "self-block" in the lateral accesses (32,33).
Des obturateurs amovibles (non représentés) pourront être prévus pour protéger les ouvertures réalisant les accès latéraux al in de protéger les lamelles. De manière préférentielle, la connexion mécanique entre le socle et le bac est réalisée par deux systèmes de fixation rapide (36).Removable shutters (not shown) may be provided to protect the openings making the lateral accesses in order to protect the slats. Preferably, the mechanical connection between the base and the tank is made by two quick fastening systems (36).
Chaque système de fixation rapide consiste en un tirant (37), par exemple en élastomère, comportant à une extrémité une goupille (38) destinée à venir se positionner dans un logement (39) réalisé à cet effet au centre de deux faces latérales opposées du socle et à l'autre extrémité une came (40) fixée pivotante destinée à venir en appui dans une rainure (42) ou autre moyen de positionnement réalisé sur le couvercle du bac et à pivoter la face supéπeure du couvercle une fois en appui dans ladite rainure.Each quick fastening system consists of a tie rod (37), for example made of elastomer, comprising at one end a pin (38) intended to be positioned in a housing (39) produced for this purpose at the center of two opposite lateral faces of the base and at the other end a pivotally fixed cam (40) intended to come to bear in a groove (42) or other positioning means produced on the cover of the container and to pivot the upper face of the cover once in support in said groove.
La longueur du tirant est fonction de la hauteur du bac. On pourra donc facilement changer un bac donné par un autre bac de dimension différente suivant sa capacité.The length of the tie rod depends on the height of the tank. It is therefore easy to change a given container by another container of different size according to its capacity.

l'enceinte de la batteπe au niveau du socle,the bat enclosure at the base,
- les connexions électπques entre le bac de la batterie, le socle et le système de mise hors circuit sont indépendantes,- the electrical connections between the battery tray, the base and the disconnection system are independent,
- les liaisons électriques internes de la batterie pour la distribution sont réalisées avant la fermeture du couvercle permettant une simplification importante de la fabπ cation industrielle de la batterie.- The internal electrical connections of the battery for distribution are carried out before the cover is closed, allowing significant simplification of the industrial manufacture of the battery.
Le système de sécurité selon F invention s' applique d' une manière générale à tout dispositif d' alimentation de type batterie monté sur un socle.The security system according to the invention applies generally to any battery-type power supply device mounted on a base.
D'autre part, l' utilisation d'un tel système ne se limite pas aux véhicules à moteur thermique mais s'étend également aux véhicules à moteur électπque, aux bateaux et généralement à tout véhicule présentant une batterie On the other hand, the use of such a system is not limited to vehicles with an internal combustion engine but also extends to vehicles with an electric motor, to boats and generally to any vehicle having a battery.
