Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rear body structure of an automobile.

[Conventional technology]

In the rear body structure of an automobile, when there is a sufficient distance between the rear wheel and the rear end of the vehicle body, the filler pipe for supplying fuel to the fuel tank is generally arranged at the rear position of the tire house. ing.

The tire house is formed, for example, as disclosed in Japanese Utility Model Laid-Open No. 61-145078, so as to surround the upper portion of the rear wheel with an appropriate gap.

However, in the case of a vehicle body structure in which the distance between the rear wheel and the rear end of the vehicle body is small, the space for arranging the filler pipe cannot be provided in the rear portion of the tire house. Therefore, as shown in FIG. The inner pipe (31) is bulged rearward to form a filler pipe insertion part (33) at the rear part of the suspension tower part (32). In addition, since a large load acts on the suspension tower portion 32, if the rear portion of the suspension tower portion 32 is simply bulged rearward, sufficient load-bearing capacity cannot be obtained. Therefore, a considerably large reinforcing member 34 is arranged between the suspension tower portion 32 and the filler pipe insertion portion 33 and integrally welded.

[Problems to be solved by the device]

However, in the conventional structure as described above, in addition to the tire house inner 31, a considerably strong reinforcing member 34 is required, and it takes a lot of man-hours to firmly and integrally join it, resulting in high cost. There was a problem of becoming.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, a rear body structure of an automobile according to the present invention is a vehicle body structure of the rear part of a vehicle in which a suspension tower portion and a filler pipe insertion portion are formed in a tire house inner. Is formed by bulging the tire house inner along the shape of the filler pipe to a height of at least about the diameter of the filler pipe inward of the vehicle body, and a recess is formed between the suspension tower portion and the filler pipe insertion portion. It is characterized by being formed.

[Action]

According to the above configuration, the filler pipe insertion portion is formed by bulging the tire house inner along the shape of the filler pipe to the inside of the vehicle body at a height of at least about the diameter of the filler pipe, and the suspension tower portion. Since the recess is formed between the filler pipe insertion part and the filler pipe insertion part, the tire house inner does not have to be provided with a separate reinforcing member and has sufficient rigidity and strength to withstand the load applied to the suspension tower part. You can have it.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 3 shows a rear vehicle body structure of a four-door automobile, in which a rear side opening 2 for a side door is formed in a rear portion of a side surface of the vehicle body 1. The rear edge of the opening 2 is formed by the rear pillar 3, the front edge is formed by the center pillar 4, the upper edge is formed by the roof side rail 5, and the lower edge is formed by the side sill 6. A part of the tire house 7 is arranged between the rear fender portion 8 and the rear end of the rear fender portion 8.
It is connected to the.

As shown in FIGS. 2 and 3, the rear pillar 3 is
Is formed by the rear pillar outer 9 and the rear pillar inner 10, and the lower part of the rear pillar outer 9 is
Rear fender panel forming the outer surface of the rear fender portion 8
It is joined with 11 or molded integrally. The lower end of the rear pillar inner 10 is joined to or integrally molded with the tire house outer 12 that constitutes the outside of the tire house 7, and the outer end of the tire house outer 12 and the lower end of the rear fender panel 11 are joined to each other. Has been done. At the lower part of the rear pillar inner 10, a tire house inner 13 that faces the tire house outer 12 and constitutes the inside of the tire house 7 is joined.

A fuel tank (not shown) is arranged under the floor panel of the rear seat part, and a filler pipe 14 for supplying fuel to this fuel tank passes from the upper rear position of the rear wheel to the inside of the rear wheel. Are arranged.

The rear fender panel 11 has the filler pipe 14
An opening 15 is formed in a portion facing the inlet portion 14a, and a filler box 16 holding the inlet portion 14a is fixed to the inner surface of the opening 15. The opening 15 is closed by a filler lid 17 so that it can be opened and closed. In addition, a bulging portion 18 protruding outward for reinforcement is provided at a portion of the rear pillar inner 10 through which the filler pipe 14 penetrates.
A through hole 19 is formed in the.

As shown in FIGS. 1 and 2, the tire house inner 13 includes a suspension tower portion 20 that supports the upper strut of the rear suspension member, and a filler pipe insertion portion 21 into which the filler pipe 14 is inserted. A recessed portion 22 is formed and narrowed between the suspension tower portion 20 and the filler pipe insertion portion 21. The filler pipe insertion portion 21 is formed by bulging the tire house inner 13 along the shape of the filler pipe 14 toward the inside of the vehicle body at a height of at least about the diameter of the filler pipe 14.

According to the above configuration, in the structure in which the tire house inner 13 is provided with the suspension tower portion 20 and the filler pipe insertion portion 21, the filler pipe insertion portion 21 forms the tire house inner 13 along the shape of the filler pipe 14. It is formed by bulging toward the inner side of the vehicle body to a height of at least about the diameter of the filler pipe 14, and a recess 22 is formed between the suspension tower portion 20 and the filler pipe insertion portion 21. As a result, the tire house inner 13 is simply bulged from the suspension tower portion 20 to the rear side of the vehicle body, and a tire house is provided in the rear portion of the suspension tower portion 20 as compared with a structure in which the tire pipe inner portion 13 is secured. The inner 13 can have high rigidity and strength.

Therefore, the tire house inner 13 can secure necessary rigidity and strength without providing another reinforcing member.

In the above embodiment, the tire house inner 13 is formed of a single plate material and the concave portion 22 is formed by narrowing it down. However, another member may be integrally joined.

[Effect of device]

The rear body structure of the vehicle according to the present invention is as described above.
In the vehicle body structure of the rear part of the automobile in which the suspension tower portion and the filler pipe insertion portion are formed in the tire house inner, the filler pipe insertion portion, the tire house inner, along the shape of the filler pipe at least about the diameter of the filler pipe It is formed by bulging to the inside of the vehicle body at a height, and has a configuration in which a recess is formed between the suspension tower portion and the filler pipe insertion portion.

As a result, the tire house inner has an effect that it is possible to sufficiently provide necessary rigidity and strength without providing another reinforcing member.
