DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel inlet lid provided at a fuel filler port of a motor vehicle, and more particularly to a fuel inlet lid of a motor vehicle capable of improving economy by simplifying the structure of a hinge mechanism for opening and closing the fuel inlet lid. Regarding the structure.

[0002]

2. Description of the Related Art A fuel inlet lid structure provided at a fuel filler port of an automobile is configured as shown in FIG. In the fuel inlet lid structure, a reinforcement 101 is welded to the rear surface of the fuel inlet lid body 100, and the reinforcement 10 is welded.
A pair of upper and lower cut-and-raised pieces 102, 103 provided in
One end of a hinge bracket 104 is rotatably supported via a hinge shaft 105, and the other end of the hinge bracket 104 is screwed and fixed in a fuel inlet box (not shown) on the vehicle body side.

The hinge shaft 105 is formed by bending a rod-shaped steel material into a crank shape, and has both ends 105a, 105b of the cut-and-raised pieces 102, 103 through the through-holes 102a, 1a.
The hinge bracket 104 is supported by passing one end of the hinge bracket 104 through the upper and lower flanges through 03a. The intermediate portion of the hinge shaft 105 is fixed to the reinforcement 101 by welding.

According to the above prior art, the hinge shaft 105 is welded to the fuel inlet lid body 100 or the reinforcement 101 in order to fix the hinge shaft 105 at the hinge center. In order to perform spot welding or arc welding on the hinge shaft 105, in the case of spot welding, it is necessary to crush the tip of the hinge shaft 105 or to perform bending near the tip, which increases the processing cost. Further, in the case of performing arc welding or gas welding, welding equipment for arc welding or gas welding is required, which requires skill in processing and increases costs.

[0005] On the other hand, the one shown in FIG.
07, 108, and the support brackets 107, 1
08 supports a hinge bracket 110 via a pin 109. In this case, a C-ring 111 is fitted to the tip of the pin 109 to prevent the pin 109 from coming off.

[0006]

However, according to the above prior art, the C ring 111 is easily detached, and if the C ring 111 is detached, the pin 109 is easily detached, and the fuel inlet lid main body 106 may be loose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

1 to 5, reference numeral 1 denotes a fuel inlet lid provided at a fuel filler port of a vehicle body 2 of an automobile. The fuel inlet lid 1 is spot-welded to the fuel inlet lid body 3 and the rear flange 3a of the fuel inlet lid body 3.
It is composed of the reinforcement 4 performed. The fuel inlet lid 1 is supported on the vehicle body 2 via a hinge bracket 5 attached to the reinforcement 4 so as to be openable and closable.

The reinforcement 4 is provided with a pair of upper and lower cut-and-raised pieces (supporting pieces) 6 and 7 on the plate surface. 7a are formed. A protruding piece 9 is formed integrally on one side of the upper side of the reinforcement 4 so as to be bendable. The protruding piece 9 is bent at a predetermined interval L above the cut-and-raised piece 6 on the upper side. They are provided to face each other. As shown in FIG. 6, the base of the protruding piece 9 is provided with a slight step 9 a serving as a starting point of bending, and is set so that the step 9 a can be bent using the step 9 a as a mark. This step 9a is reinforcement 4
Is processed at the time of press working. The length of the pin 8 is set so as to protrude a predetermined length E below the cut-and-raised piece 7. The length E is set so as to satisfy E> L, thereby preventing omission.

One end 5a of the hinge bracket 5 is rotatably supported between the cut-and-raised pieces 6 and 7 via a pin 8. As shown in FIG. 7, the pin 8 forms an engaging portion 8a that crushes the upper end portion and engages with the cut-and-raised piece 6. The engaging portion 8a is formed larger than the insertion hole 6a to prevent the pin 8 from coming off.
As shown in FIG. 8, as the engaging portion 8a, an engaging portion 8b can be formed at the tip of the pin 8 by so-called header processing.

A screw hole 11 for screwing to the fuel inlet box 10 on the vehicle body 2 side is formed in the other end 5b of the hinge bracket 5. An engagement piece 13 is provided at one end of the reinforcement 4 opposite to the hinge bracket 5 attachment portion, the engagement piece 13 being engaged with a fuel lid opener device 12 of a fuel inlet box 10 on the vehicle body 2 side.

According to the above construction, one end 5a of the hinge bracket 5 and the insertion holes 6a of the pair of upper and lower support pieces 6, 7 are formed.
7a, one end 5a of the hinge bracket 5 through the pin 8
Is rotatably connected to the fuel inlet lid 1. Since the pin 8 is locked by the engaging portion 8a, the pin 8 does not fall out of the insertion holes 6a and 7a of the support piece 6. next,
The protruding piece 9 is bent to lock the engaging portion 8a of the pin 8. Thus, the pin 8 is prevented from coming off upward.

According to the above embodiment, the hinge bracket 5
The fuel inlet lid body 3 and the hinge bracket 5 are rotatably connected to the one end 5a and a pair of upper and lower support pieces 6, 7 through a linear pin 8 provided with an engagement portion 8a at the upper end. A bendable protruding piece 9 is provided on the reinforcement 4 on the upper side of the support piece 6, and the pin 8 is passed through the support pieces 6 and 7 and the hinge bracket 5. Since the protruding piece 9 is bent to the side to lock the engaging portion 8a of the pin 8, the structure of the hinge mechanism for opening and closing the fuel inlet lid 1 can be simplified, and the economy can be improved. With protruding piece 9
Thus, the pin 8 can be prevented from coming off. Pin 8
Since the engaging portion 8a is formed by crushing the upper end of the pin 8, there is no need to bend the pin 8 and the processing is easy. The protruding piece 9 is protruded from the upper edge of the reinforcement 4 and is integrally formed.
Is bent toward the engaging portion 8a side of the pin 8 to prevent the pin 8 from coming off, so that a conventional welding process such as welding a pin is not required, thereby improving work efficiency and economical.
