Abstract

L'invention porte sur une structure de carrosserie de véhicule (1), laquelle structure comporte une structure de caisse de toit (10), des structures de caisse latérales (20), un dessous de châssis (40), et des sous-longerons, les sous-longerons étant disposés sur la surface inférieure du dessous de châssis (40), et des dispositifs de déplacement de jonction, et laquelle est configurée de telle manière que des heures de main d'œuvre pour fabriquer la carrosserie de véhicule sont réduites par l'élimination de tuyaux traversants et la modularisation du câblage et des tuyauteries. En des positions proches des extrémités du dessous de châssis (40) dans la direction longitudinale (120), sont disposés des sous-longerons centraux (47) au centre du dessous de châssis (40) dans la direction de la largeur (110), et sont également disposés des sous-longerons d'extrémité (48, 48) aux deux extrémités du dessous de châssis (40) dans la direction de la largeur (110). Les sous-longerons centraux (47) et les sous-longerons d'extrémité (48, 48) sont construits à partir de matériaux de forme extrudée creux ayant chacun deux plaques de surface opposées, et ayant également chacun des nervures pour relier les plaques de surface, les deux plaques de surface opposées et les nervures étant formées par moulage par extrusion en creux. Les sous-longerons centraux (47) sont agencés de telle sorte que la direction d'extrusion de ceux-ci est alignée avec la direction de la largeur (110), et les sous-longerons d'extrémité (48, 48) sont agencés de telle sorte que la direction d'extrusion de ceux-ci est alignée avec la direction longitudinale (120). En résultat de cette configuration, un câblage et des tuyauteries modularisés peuvent être passés entre les nervures qui sont formées à l'intérieur des sous-longerons d'extrémité (48, 48) et qui s'étendent dans la direction longitudinale. Par conséquent, la rigidité des sous-longerons est améliorée et les heures de main d'œuvre pour la fabrication de la carrosserie de véhicule sont réduites.
