Problems solved by technology

[0004] However, the method of supplementing the rigidity of the floor with reinforcing parts increases the cost burden
Increased body weight due to increased reinforcement
Also, for light vehicles, it is especially difficult to reinforce the floor with additional reinforcement components
This is because the space between the fuel tank and the end of the floor in the vehicle width direction is limited in a light vehicle whose size in the vehicle width direction is limited

Embodiment Construction

[0029] Refer to the following Figure 1 to Figure 10 An example of the present invention will be described.

[0030] figure 1 The body structure of the lower side of the vehicle is shown. figure 2 The floor panel (or floor) under the front seats is shown. image 3 The structure in which the fuel tank is accommodated under this floor is shown. Figure 4 and Figure 5 Sections of each part of the structure are shown separately.

[0031] exist Figure 1 to Figure 3 In the figure, 1 denotes a pair of side sills arranged on the outermost sides on both sides in the vehicle width direction and constituting the skeleton of the vehicle body 2 . 3 denotes a pair of side sills arranged inside the pair of side sills 1 and close to the center of the vehicle body. This side rail (side rail) 3 is an example of the side rail in this invention. Furthermore, these side sills 1 and 3 extend in the front-rear direction of the vehicle body.

[0032] Between the pair of side sills 1 and 1...

Abstract

In this car body structure, the bulged part 15 for housing the upside of the fuel tank 12 is formed on a floor panel part 17 for installing a front seat 10 in the floor panel 6 by deep drawing with at least the flat panel part 17a to 17c extending from the base of the bulged part 15 to the front edge of the vehicle and the side edges at both sides in the width direction left undone. The flat floor panel parts 17a to 17c extending to the base of the bulged part 15 separated from the front edge and the side edges of the floor panel 6 are the parts to which the skeleton members of the car body 2 can be fixed. Thus, the floor panel 6 can be reinforced by utilizing the skeleton members of the car body.

Description

technical field [0001] The present invention relates to a vehicle body structure capable of accommodating a fuel tank under a floor provided with front seats. Background technique [0002] In automobiles, there is a technique of installing large on-vehicle equipment such as a fuel tank in the space under the front seats in order to effectively utilize the space in the vehicle interior. In such a vehicle body structure, a bulging portion that bulges into the vehicle interior is formed on a floor portion under the front seats. The upper part of the fuel tank is housed in the bulge. [0003] Conventionally, regarding such a structure for accommodating a fuel tank under the front seats, as disclosed in Japanese Patent Application Laid-Open No. 2000-85382, a raised portion protruding into the vehicle interior is formed on the floor portion under the front seats. . The bulging portion spans the entire area in the vehicle width direction, that is, the entire area between the sid...
