Description

Véhicule automobile comportant une motorisation électrique ou hybride et un dispositif de protection de l’ensemble de batterieMotor vehicle comprising an electric or hybrid motorization and a protection device for the battery assembly

L’invention se rapporte au domaine de la structure des véhicules à motorisation électrique ou hybride.The invention relates to the field of the structure of vehicles with electric or hybrid motorization.

Les véhicules électriques ou hybrides comporte un ensemble de batterie pour alimenter le ou les moteurs électrique(s) assurant la propulsion du véhicule, l’ensemble de batterie étant généralement disposé dans un bac batterie.Electric or hybrid vehicles include a battery assembly to power the electric motor(s) providing propulsion of the vehicle, the battery assembly generally being placed in a battery box.

Lorsque le bac batterie est disposé sous le véhicule, au niveau du châssis du véhicule, celui-ci est susceptible d’être atteint par des projectiles tels que des pierres, et de subir des dommages dans certaines situations de conduites, comme par exemple lorsque le véhicule est amené à descendre un trottoir ou une marche.When the battery tray is placed under the vehicle, at the level of the vehicle chassis, the latter is liable to be hit by projectiles such as stones, and to suffer damage in certain driving situations, such as when the vehicle is driven down a curb or step.

Il existe donc un besoin pour les véhicules comportant une motorisation électrique ou hybride de prévoir une protection spécifique permettant de protéger le bac batterie.There is therefore a need for vehicles comprising an electric or hybrid engine to provide specific protection making it possible to protect the battery compartment.

L’invention a ainsi pour but de proposer un dispositif de protection de la partie avant d’un bac batterie, qui puisse être fixé à la structure d’un véhicule sans nécessiter de modifications importantes, et qui puisse être démonté facilement pour accéder aux éléments protégés par ce dispositif et/ou à des éléments situés à proximité immédiate de ce dispositif.The object of the invention is thus to propose a device for protecting the front part of a battery box, which can be fixed to the structure of a vehicle without requiring major modifications, and which can be easily dismantled to access the elements. protected by this device and/or to elements located in the immediate vicinity of this device.

A cet effet, l’invention concerne véhicule automobile comportant un ensemble de batterie pour l’alimentation d’une motorisation électrique, l’ensemble de batterie étant disposé dans un bac batterie disposé au niveau d’un châssis du véhicule, le véhicule comportant un dispositif de protection d’une partie avant du bac batterie, le dispositif de protection étant fixé à un élément de structure solidaire du châssis du véhicule, le dispositif de protection comportant un élément de protection fixé à cet élément de structure par l’intermédiaire de deux éléments de fixation, de sorte que le démontage de l’élément de protection peut être réalisé sans nécessiter le démontage des éléments de fixation.To this end, the invention relates to a motor vehicle comprising a battery assembly for supplying an electric motor, the battery assembly being placed in a battery box placed at the level of a chassis of the vehicle, the vehicle comprising a protection device for a front part of the battery box, the protection device being fixed to a structural element secured to the chassis of the vehicle, the protection device comprising a protection element fixed to this structural element by means of two fixing elements, so that the dismantling of the protection element can be carried out without requiring the dismantling of the fixing elements.

Ainsi, en prévoyant un dispositif de protection comportant plusieurs éléments, dont un élément de protection et au moins deux éléments de fixation, il est possible, en cas d’intervention, de démonter l’élément de protection indépendamment des éléments de fixation. Cela permet ainsi de pouvoir fixer les éléments de fixation à la structure du véhicule avec des contraintes relatives aux éléments dits sécuritaires (ce qui implique, entre autres, l’application d’un couple de serrage dit « sécuritaire » en cas de fixation par vissage). Il est alors possible de fixer les éléments de fixation au niveau de points de fixation préexistants, comme par exemple les points de fixation d’un support de fixation d’un berceau avant. L’invention permet donc d’utiliser des points de fixation existants pour la fixation du dispositif de protection, même si ceux-ci imposent des contraintes spécifiques, puisque des contraintes moins strictes pourront être mises en œuvre pour la fixation de l’élément de protection sur les éléments de fixation.Thus, by providing a protective device comprising several elements, including a protective element and at least two fixing elements, it is possible, in the event of an intervention, to dismantle the protective element independently of the fixing elements. This thus makes it possible to be able to fix the fastening elements to the structure of the vehicle with constraints relating to the so-called security elements (which implies, among other things, the application of a so-called "safe" tightening torque in the event of fastening by screwing ). It is then possible to fix the fixing elements at the level of pre-existing fixing points, such as for example the fixing points of a fixing support of a front subframe. The invention therefore makes it possible to use existing fixing points for fixing the protective device, even if these impose specific constraints, since less strict constraints can be implemented for fixing the protective element. on the fasteners.

Dans une réalisation, l’élément de structure auquel est fixé le dispositif de protection est un support de fixation d’un berceau avant, le support de fixation étant fixé au châssis du véhicule.In one embodiment, the structural element to which the protective device is attached is a mounting bracket for a front subframe, the mounting bracket being attached to the vehicle chassis.

Dans une réalisation, les éléments de fixation du dispositif de protection sont fixés au support de fixation au niveau d’au moins deux points de fixation, au niveau desquels le berceau avant est lui-même fixé au support de fixation.In one embodiment, the attachment elements of the protection device are attached to the attachment bracket at at least two attachment points, at which the front subframe is itself attached to the attachment bracket.

Dans une réalisation, les éléments de fixation du dispositif de protection sont fixés au support de fixation par vissage.In one embodiment, the fixing elements of the protection device are fixed to the fixing support by screwing.

Dans une réalisation, l’élément de protection est fixé à chaque élément de fixation au niveau de points de fixation distincts des points de fixation des éléments de fixation.In one embodiment, the protection element is attached to each attachment element at attachment points separate from the attachment points of the attachment elements.

Dans une réalisation, l’élément de protection est fixé à chaque élément de fixation par vissage.In one embodiment, the protection element is fixed to each fixing element by screwing.

Dans une réalisation, l’élément de protection est réalisé dans un matériau métallique, par exemple à partir d’un profilé métallique.In one embodiment, the protection element is made of a metallic material, for example from a metallic profile.

Dans une réalisation, les éléments de fixation sont réalisés dans un matériau métallique.In one embodiment, the fixing elements are made of a metallic material.

Dans une réalisation, le véhicule automobile comporte une motorisation électrique ou hybride.In one embodiment, the motor vehicle comprises an electric or hybrid motorization.

La présente invention sera mieux comprise à la lecture de la description détaillée qui suit, faite en référence aux dessins annexés, dans lesquels :The present invention will be better understood on reading the following detailed description, made with reference to the accompanying drawings, in which:

La figure est une vue de dessous d’une partie avant de la structure d’un véhicule automobile à motorisation électrique ou hybride électrique. The figure is a view from below of a front part of the structure of a motor vehicle with electric or electric hybrid motorization.

La illustre la structure de la équipée d’un dispositif de protection conformément à l’invention. There illustrates the structure of the equipped with a protection device according to the invention.

La est une vue partielle en coupe transversale de la structure de la , illustrant une configuration de fixation d’un dispositif de protection conforme à l’invention. There is a partial cross-sectional view of the structure of the , illustrating an attachment configuration of a protective device according to the invention.

La est une vue de dessous de la structure avant d’un véhicule 1 automobile. Le véhicule 1 comporte un châssis 10 et un berceau avant 12, ou berceau moteur. Le berceau avant 12 est fixé au châssis notamment par l’intermédiaire d’un support de fixation 14 solidaire du châssis 10. Le support de fixation 14 du berceau avant 12 est dans l’exemple fixé au châssis notamment au niveau de quatre points de fixations 14a, 14b. A proximité du berceau avant 12, en arrière de celui-ci, se trouve une extrémité avant d’un bac batterie 16, contenant un ensemble de batterie destiné à alimenter un ou plusieurs moteur(s) électrique(s) assurant la propulsion du véhicule 1. Le bac batterie 16 est dans l’exemple au moins partiellement fixé au support de fixation 14. Au niveau d’une partie avant centrale 16a du bac batterie 16, couramment dénommée nez de batterie 16a, se trouvent des dispositifs de connexion 16b, incluant par exemple des connecteurs pour un dispositif de refroidissement hydraulique de l’ensemble de la batterie, des connecteurs électriques pour relier l’ensemble de batterie à un moteur électrique, et des connecteurs électriques pour alimenter des dispositifs autres que le moteur électrique. L’ensemble de ces éléments, ainsi que le bac batterie 16, doivent être protégés contre des chocs, dont notamment les chocs dus à la projection de pierres. Cette protection est assurée, conformément à l’invention, grâce au dispositif de protection 2 visible sur les figures 2 et 3 et décrit plus en détail ci-après.There is a bottom view of the front structure of a motor vehicle 1. The vehicle 1 comprises a chassis 10 and a front cradle 12, or engine cradle. The front cradle 12 is fixed to the chassis in particular by means of a fixing support 14 integral with the chassis 10. The fixing support 14 of the front cradle 12 is in the example fixed to the chassis in particular at four fixing points 14a, 14b. Close to the front subframe 12, behind the latter, is a front end of a battery box 16, containing a battery assembly intended to supply one or more electric motor(s) ensuring the propulsion of the vehicle. 1. The battery tray 16 is in the example at least partially fixed to the mounting bracket 14. At a central front part 16a of the battery tray 16, commonly referred to as the battery nose 16a, there are connection devices 16b, including, for example, connectors for a device for hydraulically cooling the battery assembly, electrical connectors for connecting the battery assembly to an electric motor, and electrical connectors for powering devices other than the electric motor. All of these elements, as well as the battery tray 16, must be protected against shocks, including in particular shocks due to the projection of stones. This protection is ensured, in accordance with the invention, thanks to the protection device 2 visible in FIGS. 2 and 3 and described in more detail below.

La montre la structure avant de la , la structure avant étant équipée d’un dispositif de protection 2 conforme à l’invention. Le dispositif de protection 2 comporte un élément de protection 20, fixé à la structure du véhicule 1 par l’intermédiaire de deux éléments de fixation 22a, 22b. Chacun des éléments de fixation 22a, 22b est fixé au support de fixation 14, au niveau des points de fixation 14a, 14b.There shows the front structure of the , the front structure being equipped with a protective device 2 according to the invention. The protective device 2 comprises a protective element 20, fixed to the structure of the vehicle 1 via two fixing elements 22a, 22b. Each of the fixing elements 22a, 22b is fixed to the fixing support 14, at the level of the fixing points 14a, 14b.

Comme montré sur la , l’élément de protection 20 est fixé à chaque élément de fixation 22a, 22b en au moins un point de fixation 20a, 20b, distinct des points de fixation 14a, 14b. Dans l’exemple, l’élément de protection 20 est fixé à chaque élément de fixation 22a, 22b au niveau de deux points de fixation 20a, 20b, qui sont décalés par rapport aux points de fixations 14a, 14b. Dans l’exemple des figures, le dispositif de fixation 14 est fixé au moyen de vis 14c, et l’élément de protection 20 est fixé aux éléments de fixation 22a, 22b au moyen de vis 24 coopérant avec des écrous. L’élément de protection 20 comporte des ouvertures au droit des vis 24, permettant d’insérer un outil pour procéder au serrage et au desserrage des vis 24 lorsque l’on souhaite monter ou démonter l’élément de protection 20.As shown on the , the protection element 20 is fixed to each fixing element 22a, 22b at at least one fixing point 20a, 20b, distinct from the fixing points 14a, 14b. In the example, the protection element 20 is fixed to each fixing element 22a, 22b at the level of two fixing points 20a, 20b, which are offset with respect to the fixing points 14a, 14b. In the example of the figures, the fixing device 14 is fixed by means of screws 14c, and the protective element 20 is fixed to the fixing elements 22a, 22b by means of screws 24 cooperating with nuts. The protection element 20 has openings in line with the screws 24, making it possible to insert a tool for tightening and loosening the screws 24 when it is desired to mount or dismount the protection element 20.

La fixation de l’élément de protection 20 par l’intermédiaire de deux éléments de fixation 22a, 22b permet de prévoir la fixation desdits éléments de fixation 22a, 22b sur le support de fixation 14 en respectant les contraintes relatives aux éléments dits « sécuritaires », et de prévoir la fixation de l’élément de protection 20 avec des contraintes moins strictes. En pratique, les éléments de fixation 22a, 22b seront fixés au moyen d’éléments vissés avec un couple de serrage dit « sécuritaire », impliquant notamment qu’un éventuel démontage devra impérativement être effectué par un professionnel. En revanche, ces contraintes ne s’appliqueront pas à la fixation de l’élément de protection 20, qui pourra donc être démonté et remonté de façon moins contraignante. En particulier, il ne sera pas obligatoire que le démontage de cet élément soit impérativement réalisé par un professionnel. Le dispositif de protection 2 sera configuré pour résister à tous les types de chocs susceptibles d’être rencontrés compte tenu de l’emplacement du bac batterie, et notamment les chocs de type projection de pierre.The fixing of the protection element 20 by means of two fixing elements 22a, 22b makes it possible to provide the fixing of said fixing elements 22a, 22b on the fixing support 14 while respecting the constraints relating to the so-called "safe" elements. , and to provide the fixing of the protection element 20 with less strict constraints. In practice, the fixing elements 22a, 22b will be fixed by means of elements screwed with a so-called “safe” tightening torque, implying in particular that any disassembly must imperatively be carried out by a professional. On the other hand, these constraints will not apply to the fixing of the protective element 20, which can therefore be disassembled and reassembled in a less restrictive way. In particular, it will not be compulsory for the dismantling of this element to be carried out by a professional. The protection device 2 will be configured to withstand all types of shock likely to be encountered given the location of the battery tray, and in particular stone projection type shocks.
