Wire and pipe-laying structure for fuel cell vehicle
A wire and pipe-laying structure for a fuel cell vehicle including a rear frame which is disposed at a back of the fuel cell vehicle and extends in a longitudinal direction of the fuel cell vehicle; a side sill which is disposed at a side of the fuel cell vehicle; and a floor frame which is disposed inside the side sill and extends in a longitudinal direction of the fuel cell vehicle. The floor frame together with the side sill are connected to a front end of the rear frame so as to form a Y-shaped frame having a crotch portion. A fuel pipe or a high-voltage wiring is disposed so as to pass through the crotch portion of the Y-shaped frame, and the fuel pipe or high-voltage wiring connects a fuel tank for fuel gas or a storage device to a fuel cell box.
1. A wire and pipe-laying structure for a fuel cell vehicle, comprising:
a rear frame which is disposed at a back of said fuel cell vehicle and extends in a longitudinal direction of said fuel cell vehicle;
a side sill which is disposed at a side of said fuel cell vehicle;
a floor frame which is disposed inside said side sill and extends in a longitudinal direction of said fuel cell vehicle, said floor frame together with said side sill being connected to a front end of said rear frame so as to form a Y-shaped frame having a crotch portion, and
a fuel pipe or a high-voltage wiring which is disposed so as to pass through said crotch portion of said Y-shaped frame, said fuel pipe or said high-voltage wiring connecting a fuel tank for fuel gas or a storage device to a fuel cell box, wherein
said fuel tank for fuel gas is supported by a sub-frame which is connected to an underside of said rear frame, said fuel tank being positioned under a rear floor;
said fuel cell box is disposed under said floor frame under a front floor, said front floor being positioned lower than said rear floor, and
said fuel pipe extends horizontally from an underside of said sub-frame in a front direction, said fuel pipe having at least one loop in said crotch portion formed by said Y-shaped frame and being connected to said fuel cell box.
2. A wire and pipe-laying structure for a fuel cell vehicle according to claim 1 , wherein
said Y-shaped frame is formed at a right hand side and a left hand side of said fuel cell vehicle;
said fuel tank and said storage device are disposed at said rear frame side; and
said fuel pipe is allocated for said crotch portion of one of said right hand side and left hand side Y-shaped frames, and said high-voltage wiring is allocated for said crotch portion of the other one of said right hand side and left hand side Y-shaped frames, wherein
said storage device is disposed on said rear floor,
said high-voltage wiring extends into the crotch portion of one of said Y-shaped frames, said high-voltage wiring having at least one bent portion, and
said bent portion is covered with a cover.
