Abstract

L'invention concerne une structure de guidage de harnais pour automobile électrique grâce auquel, lorsqu'un bloc d'alimentation et un port de charge sont raccordés par un harnais de charge, il est possible d'éviter l'augmentation des dimensions du châssis dans le sens de la longueur du véhicule. Un bloc d'alimentation (10) élastiquement maintenu par un élément latéral avant (3) et par un premier élément transversal avant (4A), et un port de charge rapide (31) (port de charge) qui est solidement maintenu par un second élément transversal avant (4B), sont raccordés par un harnais de charge rapide (43). En plus d'être retenu par un clip (51) de harnais de charge rapide qui accroche un élément intermédiaire du harnais de charge rapide (43) au second élément transversal avant (4B) et par un second clip (52) de harnais de charge rapide qui accroche l'élément intermédiaire dudit harnais (43) au bloc d'alimentation (10); la hauteur du premier clip (51) de harnais de charge rapide et la hauteur du second clip (52) de harnais de charge rapide sont différentes.
