Description

Partie arrière de véhicule automobile comportant un moteur électrique alimenté par un module d'alimentation Rear part of a motor vehicle comprising an electric motor powered by a power supply module
La présente invention concerne une partie arrière de véhicule automobile comportant un moteur électrique alimenté par un module d'alimentation. Classiquement, ladite partie comprend un coffre délimité à sa partie arrière, par une traverse et à sa partie inférieure, par un plancher adapté pour permettre la fixation du module d'alimentation à l'intérieur du coffre.The present invention relates to a rear part of a motor vehicle comprising an electric motor powered by a power supply module. Conventionally, said part comprises a chest delimited at its rear part, by a cross member and at its lower part, by a floor adapted to allow the attachment of the power module inside the trunk.
Le module d'alimentation comprend un bac et un couvercle destinés à recevoir et à protéger un dispositif amenant de l'énergie et/ou de la puis- sance au moteur électrique.The power module includes a tray and a lid for receiving and protecting a device supplying power and / or power to the electric motor.
Un tel module doit être conçu de manière robuste, il doit être un lieu de stockage rigide résistant aux agressions extérieures, et étanche, afin d'éviter toute diffusion des gaz du module dans l'habitacle du véhicule.Such a module must be robustly designed, it must be a rigid storage area resistant to external aggression, and waterproof, to prevent any diffusion of module gas in the passenger compartment of the vehicle.
Le positionnement du module d'alimentation des véhicules hybrides ou électriques représente une difficulté lors de la définition de l'architecture de la structure de ces véhicules. En effet, le module d'alimentation doit être conçu pour assurer une autonomie correcte au véhicule et, par conséquent, présente un volume important et une masse élevée.The positioning of the power module of hybrid or electric vehicles represents a difficulty in defining the architecture of the structure of these vehicles. Indeed, the power module must be designed to ensure proper autonomy of the vehicle and, therefore, has a large volume and a high mass.
L'une des implantations envisagée est le coffre, disposé à l'arrière des véhicules. Toutefois, en cas de choc arrière, ou d'encastrement, choc arrière spécifique consistant à un choc heurtant la partie haute de l'arrière du véhicule, le module d'alimentation risque d'être endommagé ; le véhicule risque donc de ne pas satisfaire aux tests réglementaires.One of the implantations envisaged is the trunk, placed at the rear of the vehicles. However, in the event of a rear impact, or recessing, with a specific rear impact consisting of an impact striking the upper part of the rear of the vehicle, the power supply module may be damaged; the vehicle may therefore not meet the regulatory tests.
Afin de palier à cet inconvénient, il a été envisagé dans l'art antérieur de renforcer le bac et le couvercle appartenant un module d'alimentation, en disposant autour du bac et du couvercle une coque protectrice. Cet agencement permet au module de résister à des chocs plus importants mais a pour inconvénient d'alourdir considérablement la masse du véhicule. En effet, afin d'obtenir un rôle protecteur la coque est de préférence métallique et présente une certaine épaisseur.In order to overcome this drawback, it has been envisaged in the prior art to reinforce the tray and the lid belonging to a feed module, by placing a protective shell around the tray and the lid. This arrangement allows the module to withstand larger shocks but has the disadvantage of significantly increase the mass of the vehicle. Indeed, in order to obtain a protective role, the shell is preferably metallic and has a certain thickness.
Le document JP 2002186101 présente un absorbeur de chocs disposé à l'avant du module d'alimentation, entre ledit module d'alimentation et le passage de roue du véhicule, cet absorbeur est constitué par le tuyau reliant le module d'alimentation à son système de refroidissement. Un tel agence- ment est adapté au module d'alimentation de petite taille et ne permet pas de garantir une protection suffisante audit module. L'invention a pour but de palier à ces différents inconvénients en proposant une partie arrière de véhicule protégeant efficacement le module d'alimentation du véhicule, quelque soit la taille de ce dernier, tout limitant au strict nécessaire l'alourdissement du véhicule. L'invention a donc pour objet une partie arrière de véhicule automobile comportant un moteur électrique alimenté par un module d'alimentation, ladite partie comprenant un coffre délimité à sa partie arrière, par une traverse et à sa partie inférieure, par un plancher adapté pour permettre la fixation du module d'alimentation à l'intérieur du coffre, caractérisée en ce qu'elle comprend un dispositif de retenu disposé à l'intérieur du coffre, destiné à protéger ledit module en cas de choc arrière ou d'encastrement.JP 2002186101 discloses a shock absorber disposed at the front of the power module, between said power supply module and the wheel well of the vehicle, this absorber is constituted by the pipe connecting the power supply module to its system cooling. Such an arrangement is adapted to the small power supply module and does not provide sufficient protection for said module. The invention aims to overcome these disadvantages by providing a rear portion of the vehicle effectively protecting the power supply module of the vehicle, whatever the size of the latter, while limiting the necessary weighting of the vehicle. The subject of the invention is therefore a rear part of a motor vehicle comprising an electric motor powered by a supply module, said part comprising a boot delimited at its rear part by a cross member and at its lower part by a floor adapted to allow the attachment of the power module inside the trunk, characterized in that it comprises a retaining device disposed inside the trunk, for protecting said module in case of rear impact or embedding.
