Description
Domaine technique de l’inventionTechnical field of the invention
L’invention concerne les véhicules, éventuellement de type automobile, et plus précisément les structures que comprennent ces véhicules.The invention relates to vehicles, possibly of the automobile type, and more specifically to the structures that these vehicles comprise.
Etat de la techniqueState of the art
De nombreux véhicules, généralement de type automobile, comprennent une structure comportant au moins deux éléments (structurels) définissant des montants (ou « pieds »), droit et gauche, devant se déformer sans se casser lorsqu’ils subissent un choc latéral. Il est en effet souhaité qu’en cas de choc latéral (ou transversal) la partie inférieure d’un montant puisse se déformer plus que ses parties centrale et supérieure afin d’optimiser la protection du passager voisin.Many vehicles, generally of the automobile type, comprise a structure comprising at least two (structural) elements defining uprights (or “feet”), right and left, which must deform without breaking when they undergo a side impact. It is in fact desirable that in the event of a side (or transverse) impact, the lower part of a pillar can deform more than its central and upper parts in order to optimize the protection of the neighboring passenger.
Dans certains véhicule, on est contraint, par exemple pour une question de place et/ou de poids, de rendre la partie inférieure des montants précités plus fine que leur partie centrale, et donc en cas de choc latéral subi par un montant sa partie inférieure se déforme beaucoup trop, voire se casse, ce qui l’empêche d’assurer correctement sa fonction de protection.In some vehicles, one is forced, for example for a question of space and/or weight, to make the lower part of the aforementioned uprights thinner than their central part, and therefore in the event of a side impact suffered by an upright its lower part deforms too much, or even breaks, which prevents it from properly performing its protective function.
Il a été proposé dans le document brevet KR1996-0033983 d’adjoindre à la structure du véhicule deux barres longilignes rigides, droite et gauche, et inclinées afin d’être solidarisées fixement et respectivement aux parties inférieures des montants centraux et au plancher. Cela permet de renforcer la rigidité transversale de la structure du véhicule. Mais, en cas de choc latéral subi par une partie inférieure d’un montant central, la forte rigidité de la barre longiligne (ou raidisseur) associé(e) provoque la rupture de cette partie inférieure au-dessus de l’endroit où est solidarisée cette barre longiligne, ce qui empêche cette partie inférieure d’assurer correctement sa fonction de protection par déformation.It was proposed in the patent document KR1996-0033983 to add to the structure of the vehicle two rigid slender bars, right and left, and inclined in order to be secured fixedly and respectively to the lower parts of the central pillars and to the floor. This reinforces the transverse rigidity of the vehicle structure. However, in the event of a side impact suffered by a lower part of a central upright, the high rigidity of the associated longilinear bar (or stiffener) causes the rupture of this lower part above the place where the this slender bar, which prevents this lower part from correctly ensuring its function of protection by deformation.
L’invention a donc notamment pour but d’améliorer la situation.The aim of the invention is therefore in particular to improve the situation.
Présentation de l’inventionPresentation of the invention
Elle propose notamment à cet effet un véhicule comprenant une structure comportant au moins deux montants droit et gauche comprenant chacun une partie inférieure solidarisée fixement à un plancher.In particular, it proposes for this purpose a vehicle comprising a structure comprising at least two right and left uprights each comprising a lower part fixedly secured to a floor.
Ce véhicule se caractérise par le fait que sa structure comprend en outre deux pièces de renfort, droite et gauche, solidarisées fixement chacune à l’une des parties inférieures et au plancher, et présentant une forme générale d’équerre inversée propre, par déformation, à absorber une partie au moins d’une énergie d’un choc latéral subi par la partie inférieure associée.This vehicle is characterized in that its structure further comprises two reinforcing parts, right and left, each fixedly secured to one of the lower parts and to the floor, and having a general shape of its own inverted square, by deformation, to absorb at least part of a side impact energy undergone by the associated lower part.
Ainsi, en cas de choc latéral subi par une partie inférieure, c’est l’ensemble (pièce de renfort plus partie inférieure) qui se déforme sans que la partie inférieure ne se casse, ce qui permet à cette dernière d’assurer correctement sa fonction de protection vis-à-vis d’un passager voisin.Thus, in the event of a side impact suffered by a lower part, it is the assembly (reinforcement piece plus lower part) which deforms without the lower part breaking, which allows the latter to correctly ensure its protective function vis-à-vis a neighboring passenger.
Le véhicule selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :The vehicle according to the invention may include other characteristics which may be taken separately or in combination, and in particular:
- chaque pièce de renfort peut comprendre, d’une part, une première partie s’étendant depuis la partie inférieure associée suivant une direction transversale du véhicule et sensiblement parallèlement au plancher, et, d’autre part, une deuxième partie prolongeant cette première partie vers le bas ;- each reinforcing piece may comprise, on the one hand, a first part extending from the associated lower part in a transverse direction of the vehicle and substantially parallel to the floor, and, on the other hand, a second part extending this first part down ;
- en présence de la première option, chaque première partie peut être parallèle au plancher ;- in the presence of the first option, each first part can be parallel to the floor;
- également en présence de la première option, chaque deuxième partie peut faire un angle avec la première partie associée qui est compris entre 90° et 100° ;- also in the presence of the first option, each second part can form an angle with the associated first part which is between 90° and 100°;
- également en présence de la première option, chaque première partie peut comprendre au moins un bord transversal replié vers le bas et propre à accroître une raideur transversale de sa pièce de renfort ;- also in the presence of the first option, each first part may comprise at least one transverse edge folded downwards and capable of increasing the transverse stiffness of its reinforcing piece;
- également en présence de la première option, chaque première partie peut comprendre sur au moins un bord transversal, à proximité de la deuxième partie associée, une découpe arrondie vers l’intérieur et propre à permettre une déformation par rotation ;- also in the presence of the first option, each first part may comprise on at least one transverse edge, close to the associated second part, a cutout rounded inwards and capable of allowing deformation by rotation;
- également en présence de la première option, chaque pièce de renfort peut comprendre, d’une part, une troisième partie prolongeant la première partie vers le haut et solidarisée fixement à la partie inférieure associée par au moins un point de soudure, et, d’autre part, une quatrième partie prolongeant la deuxième partie au-dessus du plancher et solidarisée fixement à ce dernier par au moins un point de soudure ;- also in the presence of the first option, each reinforcing part may comprise, on the one hand, a third part extending the first part upwards and fixedly secured to the associated lower part by at least one spot weld, and, d on the other hand, a fourth part extending the second part above the floor and fixedly secured to the latter by at least one spot weld;
- également en présence de la première option, chaque première partie peut comprendre au moins un trou traversant permettant une fixation d’un équipement du véhicule ;- also in the presence of the first option, each first part may comprise at least one through hole allowing attachment of vehicle equipment;
- en présence de la dernière sous-option, l’équipement peut être une garniture ;- in the presence of the last sub-option, the equipment can be a fitting;
