Description
La présente invention concerne un véhicule automobile comportant une batterie électrique et un support métallique fixé au-dessus.The present invention relates to a motor vehicle comprising an electric battery and a metal support fixed above.
Les véhicules automobiles comportent généralement une batterie du réseau de bord comprenant sur le dessus des bornes de connexion reliées à des cosses de ce réseau, qui est disposée en partie supérieure d’un compartiment moteur formé à l’avant du véhicule.Motor vehicles generally comprise an on-board network battery comprising on the top connection terminals connected to lugs of this network, which is arranged in the upper part of an engine compartment formed at the front of the vehicle.
Les véhicules automobiles doivent répondre à des normes d’homologation en cas d’accident, comprenant des impacts sur l’avant du véhicule qui provoquent une déformation et un recul d’éléments disposés devant la batterie du réseau de bord.Motor vehicles must meet homologation standards in the event of an accident, including impacts on the front of the vehicle which cause deformation and recoil of elements arranged in front of the on-board network battery.
Dans le cas où des éléments métalliques arrivent en contact avec la borne positive de la batterie, on a alors un risque de court-circuit débitant une très forte intensité de courant qui peut entraîner un départ d’incendie du véhicule.If metal parts come into contact with the positive terminal of the battery, there is then a risk of a short-circuit delivering a very high current intensity which could cause the vehicle to catch fire.
Pour protéger une batterie de véhicule automobile en cas de choc avant sur ce véhicule, un type de protection connu, présenté notamment par le document FR-A1-2990068, comporte un capot réalisé dans un matériau rigide isolant disposé verticalement en avant de la batterie, qui forme un écran empêchant que des parties métalliques devant ce capot viennent directement au contact des bornes de la batterie.To protect a motor vehicle battery in the event of a front impact on this vehicle, a known type of protection, presented in particular by the document FR-A1-2990068, comprises a cover made of a rigid insulating material placed vertically in front of the battery, which forms a screen preventing metal parts in front of this cover from coming directly into contact with the battery terminals.
Toutefois pour un véhicule comportant des supports métalliques disposés juste au-dessus de la batterie, en arrière de la borne positive, un choc avant sur le véhicule entraînant un recul de cette batterie, déplace la borne positive et sa cosse qui peuvent entrer en contact avec le support disposé juste au-dessus. On a alors un risque de court-circuit.However, for a vehicle with metal brackets placed just above the battery, behind the positive terminal, a front impact on the vehicle causing the battery to recoil, displacing the positive terminal and its terminal which may come into contact with the support placed just above. There is then a risk of short circuit.
La présente invention a notamment pour but d’éviter ces problèmes de l’art antérieur.The object of the present invention is in particular to avoid these problems of the prior art.
Elle propose à cet effet un véhicule automobile comportant une batterie électrique, et un support métallique disposé à plat au-dessus de cette batterie suivant la direction verticale du véhicule, présentant un bord avant qui est disposé par rapport au sens avant de marche du véhicule, en arrière d'une borne de connexion de la batterie couverte par un capot de protection, ce véhicule étant remarquable en ce que le support métallique comporte en arrière de la borne une protection isolante couvrant le bord avant de ce support, le dessous de cette protection présentant une surface inclinée qui remonte vers l’avant, en permettant lors d’un recul du capot de protection de se glisser sous la protection isolante.It proposes for this purpose a motor vehicle comprising an electric battery, and a metal support arranged flat above this battery in the vertical direction of the vehicle, having a front edge which is arranged with respect to the forward direction of travel of the vehicle, behind a battery connection terminal covered by a protective cover, this vehicle being remarkable in that the metal support comprises, behind the terminal, an insulating protection covering the front edge of this support, the underside of this protection having an inclined surface which rises forwards, allowing during a decline of the protective cover to slip under the insulating protection.
Un avantage de ce véhicule automobile est qu’en cas d’accident avec un choc sur l’avant reculant la batterie avec une borne s’approchant du support métallique, l’appui du capot de protection sur la surface inférieure avant inclinée de la protection isolante, permet un glissement sur cette face développant sur le support une poussée vers le haut, qui entraîne son soulèvement si nécessaire, et permet à la borne avec sa cosse et son capot de protection de se glisser en dessous.An advantage of this motor vehicle is that in the event of an accident with an impact on the front pushing back the battery with a terminal approaching the metal support, the support of the protective cover on the lower front inclined surface of the protection insulating, allows sliding on this face developing an upward thrust on the support, which causes it to rise if necessary, and allows the terminal with its lug and its protective cover to slide underneath.
De cette manière on évite un choc frontal sur le bord avant du support, avec une contrainte mécanique forte qui pourrait endommager le capot de protection isolant de la cosse, et entraîner un court-circuit.In this way, a frontal impact on the front edge of the support is avoided, with strong mechanical stress which could damage the insulating protective cover of the terminal, and cause a short circuit.
Le véhicule automobile selon l’invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The motor vehicle according to the invention may also comprise one or more of the following characteristics, which may be combined with one another.
En particulier, la surface inclinée du dessous de la protection isolante peut former un plan.In particular, the inclined surface of the underside of the insulating protection can form a plane.
Avantageusement, la partie arrière de la surface du capot de protection comporte une courbe descendante qui se termine par une pointe arrière.Advantageously, the rear part of the surface of the protective cover has a downward curve which ends in a rear point.
Dans ce cas, avantageusement la pointe arrière est disposée à une hauteur inférieure à celle de l’extrémité avant de la surface inclinée du dessous.In this case, advantageously the rear point is arranged at a height lower than that of the front end of the inclined surface below.
Avantageusement, la protection isolante comporte une fente ouverte vers l’arrière, recevant de manière ajustée le support métallique pour couvrir le bord avant et le dessous de ce support.Advantageously, the insulating protection comprises a slot open towards the rear, receiving the metal support in an adjusted manner to cover the front edge and the underside of this support.
Dans ce cas, avantageusement la protection isolante comporte un dispositif de clipsage sur le support métallique.In this case, advantageously the insulating protection comprises a clipping device on the metal support.
En particulier, ce dispositif de clipsage peut comporter un crochet qui en fin de mise en place s’ajuste dans un perçage ou après un bord arrière du support métallique.In particular, this clipping device may include a hook which, when fitted, fits into a hole or after a rear edge of the metal support.
En particulier, le support métallique peut comporter des côtés verticaux de fixation sur la caisse du véhicule venant sur les côtés de la batterie.In particular, the metal support may comprise vertical sides for attachment to the body of the vehicle coming from the sides of the battery.
Avantageusement, la protection isolante est formée par un moulage d’une matière plastique.Advantageously, the insulating protection is formed by molding a plastic material.
Avantageusement, le capot de protection comporte un levier de débranchement rapide d’une cosse de raccordement fixée sur la borne.Advantageously, the protective cover includes a lever for quick disconnection of a connection lug fixed to the terminal.
L’invention sera mieux comprise et d’autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d’exemple, en référence aux dessins annexés dans lesquels :The invention will be better understood and other characteristics and advantages will appear more clearly on reading the description below given by way of example, with reference to the appended drawings in which:
Dans l’ensemble du document les côtés supérieur et inférieur et les expressions au-dessus ou en dessous, sont relatifs à un axe vertical lié à un véhicule posé sur une surface horizontale.Throughout the document, the upper and lower sides and the expressions above or below, are relative to a vertical axis linked to a vehicle resting on a horizontal surface.
La
La face supérieure de la batterie 2 comporte vers l’avant une borne positive 4 dépassant sur le dessus, recevant une cosse du faisceau du réseau de bord disposant d’un capot de protection 6 fixé à plat au-dessus, formant de plus un levier de débranchement rapide 8.The upper face of the battery 2 comprises forwards a positive terminal 4 protruding from the top, receiving a lug from the harness of the on-board network having a protective cover 6 fixed flat above, further forming a lever quick disconnect 8.
Le capot de protection 6 présentant une forme plate allongée suivant la direction longitudinale du véhicule, comporte vers l’avant un levier de manœuvre 8, qui se termine vers l’arrière au-delà de la borne 4 par une courbure descendante formant une pointe 10 arrivant au bas de ce capot.The protective cover 6 having an elongated flat shape in the longitudinal direction of the vehicle, comprises forwards an operating lever 8, which ends rearwardly beyond the terminal 4 by a downward curvature forming a point 10 arriving at the bottom of this hood.
Le capot de protection 6 forme un isolant électrique réalisé par un moulage de matière plastique, qui protège la cosse et la borne positive 4 se trouvant en dessous pour éviter en particulier lors d’opérations de maintenance, un contact avec ces éléments pouvant entraîner un court-circuit.The protective cover 6 forms an electrical insulator produced by a molding of plastic material, which protects the terminal and the positive terminal 4 located underneath to avoid, in particular during maintenance operations, contact with these elements which may cause a short -circuit.
De plus le capot de protection 6 permet de manière simple, rapide et sans outillage, à un opérateur tirant sur le levier avant 8 de détacher la cosse fixée sur la borne 4 afin de couper le branchement positif de la batterie 2 pour cesser d’alimenter le réseau de bord du véhicule.In addition, the protective cover 6 makes it easy, quick and without tools for an operator pulling the front lever 8 to detach the terminal attached to the terminal 4 in order to cut the positive connection of the battery 2 to stop supplying the vehicle's on-board network.
Un support formé par une tôle métallique découpée et pliée, comporte une face supérieure plate horizontale 14 recevant des éléments de contrôle de la batterie 2, disposée sensiblement à la hauteur du levier 8 du capot de protection 6, qui est fixée à la caisse du véhicule par des parties verticales de liaison 12. La face supérieure plate du support 14 comporte un bord droit tourné vers l’avant 16, disposé suivant la direction transversale du véhicule, qui se trouve à une dizaine de millimètres de la pointe arrière 10 du capot de protection 6.A support formed by a cut and bent metal sheet, comprises a flat horizontal upper face 14 receiving battery control elements 2, arranged substantially at the height of the lever 8 of the protective cover 6, which is fixed to the body of the vehicle. by vertical connecting parts 12. The flat upper face of the support 14 comprises a straight edge facing forwards 16, arranged in the transverse direction of the vehicle, which is about ten millimeters from the rear tip 10 of the bonnet. protection 6.
Un étrier de protection isolant 20 réalisé par un moulage de matière plastique, présente une fente horizontale ouverte vers l’arrière, recevant de manière ajustée la face supérieure du support 14 introduite par son bord avant 16. L’étrier de protection 20 comporte une partie supérieure 22 et une partie inférieure 26 enserrant la face supérieure du support 14, reliées par une boucle avant 24 qui couvre et protège le bord avant 16 de cette face.An insulating protection stirrup 20 made by molding plastic material, has a horizontal slot open towards the rear, receiving in an adjusted manner the upper face of the support 14 introduced by its front edge 16. The protection stirrup 20 comprises a part upper 22 and a lower part 26 enclosing the upper face of the support 14, connected by a front loop 24 which covers and protects the front edge 16 of this face.
L’étrier de protection 20 comporte un crochet de clipsage 30 qui après l’introduction complète de la face supérieure du support 14 au fond de la fente, descend automatiquement par rappel élastique juste après le bord arrière de cette face, afin de réaliser par clipsage un maintien de cette protection qui ne peut plus glisser vers l’avant. En variante le crochet pourrait tomber dans un perçage de la face supérieure du support 14.The protective stirrup 20 comprises a clipping hook 30 which after the complete introduction of the upper face of the support 14 at the bottom of the slot, automatically descends by elastic return just after the rear edge of this face, in order to produce by clipping maintaining this protection which can no longer slide forward. Alternatively the hook could fall into a hole in the upper face of the support 14.
Le dessous de la partie inférieure 26 de l’étrier de protection 20 présente vers l’avant une surface formant un plan incliné 28 qui monte vers l’avant, pour se terminer à une hauteur qui est un peu supérieure à celle de la pointe arrière 10 du capot de protection 6. L’étrier de protection couvre dans sa largeur sensiblement celle du capot de protection 6.The underside of the lower part 26 of the protective stirrup 20 presents towards the front a surface forming an inclined plane 28 which rises towards the front, to end at a height which is a little higher than that of the rear tip. 10 of the protective cover 6. The protective bracket covers in its width substantially that of the protective cover 6.
En cas de choc sur l’avant du véhicule qui provoque un déplacement de la batterie 2 vers l’arrière, la pointe arrière 10 du capot de protection 6 étant plus basse que l’avant du plan incliné du dessous 28, glisse alors sur la pente de ce plan incliné en provoquant si nécessaire une déformation vers le haut de la tôle du support pour permettre ce glissement.In the event of an impact on the front of the vehicle which causes the battery 2 to move backwards, the rear tip 10 of the protective cover 6 being lower than the front of the inclined plane below 28, then slides on the slope of this inclined plane by causing, if necessary, an upward deformation of the sheet metal of the support to allow this sliding.
On évite de cette manière un choc frontal sur le bord avant 16 de la face supérieure du support 14, qui pourrait causer une rupture du capot de protection 6, puis une mise en contact direct de la borne 4 ou de sa cosse avec le support métallique relié à la masse du véhicule. On assure ainsi en cas d’accident une protection contre les court-circuits débitant une forte intensité qui peut entraîner un échauffement rapide du faisceau électrique et un départ d’incendie.This avoids a frontal impact on the front edge 16 of the upper face of the support 14, which could cause a rupture of the protective cover 6, then a direct contact of the terminal 4 or its terminal with the metal support. connected to vehicle ground. In the event of an accident, this provides protection against short-circuits delivering a high current which can lead to rapid overheating of the wiring harness and a fire outbreak.
