Description

Fuel tank bracket of car body

The present invention relates to a fuel tank bracket of an automobile body, and more particularly, to a bracket structure of a fuel tank supported by a cross member installed across a side frame of a vehicle body.

As shown in FIG. 1, the vehicle body undercarriage of the vehicle is installed on the floor panel covered at the bottom, left and right sides of the floor panel, and side frames 1 extending in the front and rear directions of the vehicle body, and It comprises a cross member (2) connected across the side frames on both sides.

Here, the left and right side frames 1 are provided with lateral links 3 for reducing the inclination of the vehicle body. The lateral link 3 is coupled by hinges to the first and second brackets 4, 5 fixed to one side frame 1. In addition, the third bracket 6 is mounted between the first bracket 4 and the cross member 2 in a structure in which the third bracket 6 is connected.

The cross member 2 is provided with a fourth bracket 7 for fixing the fuel tank (not shown).

The fourth bracket 7 is simultaneously welded to the bottom and side surfaces of the cross member 2 and extends obliquely downward, as shown in detail in FIG. At the end of the fourth bracket 7 a strap 9 of the fuel tank is fixed by fastening members 8 such as bolts and nuts.

In the above-described substructure of the vehicle body, the fourth bracket supporting the fuel tank is formed to be inclined toward the front of the vehicle body, avoiding the first, second and third brackets structurally supporting the lateral link.

However, since the structure of the fourth bracket is biased toward the front of the vehicle body and is mounted on the cross member, the length of the fourth bracket is longer, the rigidity is weak, the vehicle is easily deformed by the vibration of the vehicle body, and damage of the fuel tank occurs in the rear collision accident. have.

As proposed for the purpose of solving the problems of the prior art, the present invention provides a fuel tank bracket of the vehicle body to increase the rigidity of the bracket for supporting the fuel tank, so that deformation and breakage can be prevented.

2: cross member 9: strap

11: fourth bracket 11a: first welded portion

11b: 1st extension part 11c: 1st flange surface

12: fifth bracket 12a: second welding portion

12b: 2nd extension part 12c: 2nd flange surface

12d: third flange portion

As a means for realizing the above object, the present invention provides a first welding portion attached to a side of a cross side of a cross member, and a first extension extending obliquely downward from the first welding portion, and having a strap of a fuel tank fixed at an end thereof. A fourth bracket having a portion and a first flange surface extending to both sides of the first extension portion; A second extension having a second welding portion attached to the rear side and the bottom surface of the cross member at the same time, and a second flange surface inclined downwardly from the second welding portion and welded to the first flange surface of the fourth bracket; A fuel tank bracket of a motor vehicle body comprising a fifth bracket comprising a portion and a third flange portion extending from the second extension portion and fixed with the strap of the fuel tank together with the first extension portion.

According to this configuration, the fuel tank bracket of the present invention is attached to the front and rear sides so as to completely surround the cross member, and is joined by mutual welding of the fourth and fifth brackets, thereby improving structural rigidity, deformation or breakage. This is avoided.

Hereinafter, preferred embodiments for realizing the present invention will be described in more detail with reference to the accompanying drawings.

EXAMPLE

3 is a cross-sectional view showing the connection structure of the fuel tank bracket of the vehicle body according to the present embodiment, and FIG. 4 is an exploded perspective view showing the fuel tank bracket of FIG.

In describing the present embodiment, the same reference numerals are used for the configuration of the present embodiment, which is the same as the drawings cited in the prior art, and will not be described again for clarity.

Reference numeral 2 in the drawing refers to a cross member.

A cross member 2 traversing the vehicle body is connected between the side frames that are elongated in the front and rear directions of the vehicle body.

As a means for fixing the fuel tank to the cross member 2, the fuel tank bracket according to the present embodiment includes a fourth bracket 11 connected between the cross member 2 and the fuel tank strap 9, And a fifth bracket 12 as a reinforcing material welded to the fourth bracket 11.

Here, the fourth bracket 11 extends inclined downward from the first welding portion 11a and the first welding portion 11a attached to the front side surface of the cross member 2, and the strap of the fuel tank (at the end). It consists of the 1st extension part 11b to which 9) is fixed, and the 1st flange surface 11c extended to both sides of the 1st extension part 11b.

The strap 9 of the fuel tank is fixed to the lower part of the first extension 11b by fastening members 8 such as bolts and nuts.

In addition, the fifth bracket 12 extends inclined downward from the second welding portion 12a and the second welding portion 12a which are attached to the rear side and the lower surface of the cross member 2 at the same time. A second extension portion 12b having a second flange surface 12c welded to the first flange surface 11c of (11), and a second extension portion 12b extending from the second extension portion 12b; And a third flange portion 12d fixed to the strap 9 of the fuel tank.

In the drawings, reference numeral 13 denotes a center floor panel of the vehicle body.

Based on the above configuration, in the fuel tank bracket of the present embodiment, the fourth bracket 11 and the fifth bracket 12 are welded to each other, and the first and second welds 11a and 12a are connected to each other so that the cross member 2 ) Is welded so as to enclose), so that it is formed into a closed cross-sectional structure and the joining rigidity is improved.

Therefore, the fourth bracket 11 and the fifth bracket 12 according to the present embodiment are structurally stable and rigidity is improved, thereby preventing deformation of the vehicle body and preventing damage to the fuel tank during rear collision. .

Through the embodiments described above, it can be seen that the fuel tank bracket of the vehicle body according to the present invention substantially solves the problems of the prior art.

That is, according to the present invention, the support structure of the fuel tank is stabilized and the durability is improved, so that the deformation of the vehicle body and the damage of the fuel tank are prevented.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Modifications may be made.
