Problems solved by technology

Although this arrangement method is compact, it is difficult to ensure that the fuel tank has sufficient volume, and the arrangement of the fuel tank will be close to the engine exhaust pipe, which increases the difficulty of arrangement
At the same time, the distance from the filling port at the rear of the car body to the fuel tank is increased, so the length of the filling pipe connecting the filling port and the fuel tank will inevitably be lengthened, and the oil inlet resistance of the fuel flowing through the filling pipe will also increase. large, which may result in poor refueling

Embodiment Construction

[0025] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0026] Such as figure 1 As shown, the fuel tank T is arranged on the top cover outer panel 3, the top cover inner panel 2, and the top cover middle beam 1 within the enclosed area above the vehicle. The material of the crossbeam 1 in the top cover is formed by stamping a stronger steel plate, preferably with a certain cross section, so as to better protect the integrity of the fuel tank during a side collision. The position of the fuel tank and the rear cross member 4 of the top cover can well protect the fuel tank in a rear collision.

[0027] figure 2 Zhong 5 is a kind of vibration isolation material, which can well weaken the vibration transmitted from the fuel tank to the passenger compartment during the driving process of the car, and fully guarantee the ride comfort of the pas...

Abstract

The invention relates to an arrangement structure of a fuel tank in a vehicle. The fuel tank is arranged on a roof of the vehicle and in a space which is formed by encircling inner and outer plates of a top cover, and a middle cross beam and a rear cross beam of the top cover, which changes the prior arrangement mode of the fuel tank and improves the viability of the fuel tank during the collision on the rear part; besides, the fuel tank is kept away from an air exhaust pipe, thereby reducing the danger of catching fire of the vehicle after an accident.

Description

technical field [0001] The invention relates to an arrangement structure of a fuel tank in a vehicle. Background technique [0002] In passenger cars, the traditional arrangement is to place the fuel tank under the floor of the rear seats of the vehicle. However, when the fuel tank is arranged under the rear floor, the rear space is narrow, which is not conducive to the protection of the fuel tank during the rear collision of the vehicle, and the fuel tank is close to the exhaust pipe, which is prone to fire and explosion after the collision. There are also a few arranged under the underside of the floor under the front seat. Although the arrangement is compact, the space of the passenger compartment is reduced, which affects the comfort, and it is closer to the engine exhaust pipe. [0003] Several layout structures disclosed in patent publications No. CN200410055834.9 and CN200610088584.8 are to arrange the fuel tank under the front seat pan. Although this arrangement me...
