Description
La présente invention concerne les véhicules automobiles de type hybride ou électrique dotés d’une batterie de propulsion. Elle vise en particulier ceux dont la batterie de propulsion est implantée au dessus du plancher de charge ou en dessous d’une portion surélevée de ce plancher de charge.The present invention relates to motor vehicles of the hybrid or electric type equipped with a propulsion battery. It is aimed in particular at those whose propulsion battery is located above the load floor or below a raised portion of this load floor.
Les véhicules automobiles de type électrique comprennent uniquement un moteur électrique.Motor vehicles of the electric type comprise only an electric motor.
Les véhicules automobiles de type hybride comprennent un moteur électrique en plus d’un moteur thermique. Les deux moteurs fonctionnent simultanément ou alternativement de manière à réduire la puissance totale consommée par le véhicule.Hybrid-type motor vehicles include an electric motor in addition to a heat engine. The two motors operate simultaneously or alternately so as to reduce the total power consumed by the vehicle.
La batterie de propulsion du moteur électrique est généralement logée dans un carter métallique de forme parallélépipédique implanté en partie arrière du véhicule sous les sièges des passagers arrière ou dans la zone de coffre.The propulsion battery of the electric motor is generally housed in a parallelepiped-shaped metal casing located in the rear part of the vehicle under the rear passenger seats or in the boot area.
Lorsque le carter hébergeant la batterie de propulsion est agencé dans la zone de coffre, celui-ci peut être implanté au dessus du plancher de charge du véhicule s’étendant longitudinalement entre la traverse de train et la doublure de panneau arrière portant la gâche de verrouillage de la porte ou du hayon de coffre du véhicule, et transversalement entre les deux longeronnets arrière.When the casing housing the propulsion battery is arranged in the boot area, the latter can be installed above the load floor of the vehicle extending longitudinally between the landing gear crossmember and the rear panel lining carrying the locking striker. of the door or the tailgate of the vehicle, and transversely between the two rear side members.
Ce carter peut être également implanté au dessous de ce plancher de charge au niveau d’une portion surélevée de ce dernier afin de préserver une garde au sol suffisante.This casing can also be installed below this load floor at a raised portion of the latter in order to preserve sufficient ground clearance.
D’une manière générale, les batteries de propulsion implantées dans la zone de coffre sont particulièrement exposées en cas de collisions au niveau de la partie arrière du véhicule. Un choc arrière à vitesse élevée peut par exemple provoquer une déformation importante du panneau arrière qui en avançant peut venir impacter le carter et détériorer certaines cellules de la batterie, de sorte à entrainer des fuites de liquide pouvant entrainer des risques d’électrocution ou de brûlures pour les passagers.In general, the propulsion batteries located in the boot area are particularly exposed in the event of collisions at the rear part of the vehicle. A rear impact at high speed can, for example, cause significant deformation of the rear panel which, when moving forward, can impact the casing and damage certain battery cells, so as to cause liquid leaks which can lead to the risk of electrocution or burns. for passengers.
Afin de protéger la batterie lors de la survenance d’un tel choc arrière, il est connu de l’art antérieur de prévoir un dispositif de protection comprenant une traverse s’étendant fixement entre les deux longeronnets arrière au dessus d’une portion du plancher de charge située en arrière du carter.In order to protect the battery during the occurrence of such a rear impact, it is known from the prior art to provide a protection device comprising a cross member extending fixedly between the two rear beams above a portion of the floor load located behind the housing.
Lors de la survenance d’un choc arrière à vitesse élevée, cette traverse permet de transmettre une grande partie des efforts causés par la déformation du sous-ensemble de panneau arrière aux deux longeronnets arrière, de sorte à protéger le carter et la batterie.In the event of a rear impact at high speed, this cross member transmits a large part of the forces caused by the deformation of the rear panel sub-assembly to the two rear side members, so as to protect the casing and the battery.
Toutefois, afin d’éviter que la gâche de verrouillage constituée généralement par un brin d’acier replié quasiment indéformable ne puisse passer au dessus de cette traverse lors de l’avancée du panneau arrière et ne vienne impacter le carter, un écartement longitudinal minimal est systématiquement prévu entre cette traverse et la doublure de panneau arrière.However, in order to prevent the locking striker generally consisting of an almost indeformable folded steel strand from being able to pass over this crosspiece when the rear panel is advanced and from impacting the casing, a minimum longitudinal distance is systematically provided between this crosspiece and the rear panel lining.
La nécessité de maintenir un tel écartement entraine de fait une limitation du volume de la batterie de propulsion se traduisant par une autonomie réduite du véhicule en mode de propulsion électrique.The need to maintain such a spacing leads in fact to a limitation of the volume of the propulsion battery resulting in a reduced autonomy of the vehicle in electric propulsion mode.
La présente invention vise donc à améliorer la situation.The present invention therefore aims to improve the situation.
Elle propose à cet effet un véhicule automobile de type hydride ou électrique, comportant un plancher de charge s’étendant longitudinalement entre une traverse de train et une doublure de panneau arrière portant une gâche de verrouillage d’une porte ou d’un hayon de coffre, et transversalement entre deux longeronnets arrière ; ledit véhicule comprenant également une batterie de propulsion hébergée dans un carter implanté au dessus dudit plancher de charge ou en dessous d’une portion surélevée de ce même plancher, ainsi qu’un dispositif de protection de ladite batterie comprenant une traverse s’étendant fixement entre lesdits longeronnets arrière au dessus d’une portion dudit plancher de charge située en arrière dudit carter ;
caractérisé en ce que ledit dispositif de protection comporte également un organe de retenue fixé rigidement à ladite traverse et comprenant un muret s’étendant au-dessus de ladite traverse le long d’au moins une partie de cette traverse située en vis-à-vis de ladite gâche de verrouillage.It proposes for this purpose a motor vehicle of the hybrid or electric type, comprising a load floor extending longitudinally between a cross member and a rear panel lining carrying a latch for locking a door or a tailgate. , and transversely between two rear side members; said vehicle also comprising a propulsion battery housed in a casing located above said load floor or below a raised portion of this same floor, as well as a device for protecting said battery comprising a cross member extending fixedly between said rear beams above a portion of said load floor located behind said casing;
characterized in that said protective device also comprises a retaining member rigidly fixed to said crosspiece and comprising a low wall extending above said crosspiece along at least a part of this crosspiece located opposite of said locking striker.
En cas de choc arrière à vitesse élevée, le muret de cet organe de retenue permet ainsi de bloquer l’avancée de la gâche de verrouillage passant au dessus de la traverse et d’empêcher cette gâche d’impacter le carter, de sorte à éviter tout risque de déformation et de perçage de ce dernier pouvant entrainer la détérioration de certaines cellules électrochimiques de la batterie.In the event of a rear impact at high speed, the low wall of this retaining device thus makes it possible to block the advance of the locking striker passing above the crosspiece and to prevent this striker from impacting the casing, so as to avoid any risk of deformation and piercing of the latter which could lead to the deterioration of certain electrochemical cells of the battery.
L’invention permet ainsi de réduire sensiblement voire quasiment de supprimer l’écartement longitudinal entre la traverse du dispositif de protection et la doublure de panneau arrière, de sorte à permettre d’augmenter le volume de la batterie de propulsion et en conséquence l’autonomie du véhicule en mode de propulsion électrique.The invention thus makes it possible to substantially reduce or even virtually eliminate the longitudinal gap between the crosspiece of the protection device and the rear panel lining, so as to make it possible to increase the volume of the propulsion battery and consequently the autonomy of the vehicle in electric drive mode.
