Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of the hinge portion of a fuel filler lid, and in particular, to This invention relates to a hinge part structure of a fuel filler lid, which is provided with a curved arm extending outward, and the tip of this arm is hingedly connected to a vehicle body.

[Conventional technology]

A conventional hinge structure of a fuel filler lid in a vehicle is shown in FIG. This is done by attaching a curved arm 2 to the back side of the fuel filler lid 1, and connecting the tip of this arm 2 to the fender 3 by a hinge, while always attaching the fuel filler lid 1 in the opening direction with a leaf spring 4. It's something that happens under pressure. That is, fuel filler lid 1
A curved arm 2 is fixed to the end, and this arm 2 extends to the fender 3 side beyond a flange 3a provided at the opening edge of the fender 3.
It is hinged to a hinge member 6 attached to the flange portion 3a of the fender 3 with bolts 5. The leaf spring 4 is attached to the flange portion 3a of the fender 3 together with the hinge member 6,
It extends approximately along the fuel filler lid 1 and always urges the fuel filler lid 1 in the opening direction, and the striker and the locking device are engaged by operating the fuel filler lid opener. When this is released, Fuel Fillerid 1 automatically enters the initial open state. In addition, the reference numeral 7 in the figure is a base attached to the fender 3.
(see issue).

[Problem that the invention seeks to solve]

According to the hinge structure of the conventional fuel filler lid described above, the hinge member 6 is
It is necessary to attach the spring 4 and the spring 4 to the flange portion 3a at the same time using the bolts 5, which makes the work complicated, and when the fuel filler lid 1 is in the open state, the leaf spring 4 is exposed. The problem is that it doesn't look good even when it's on.

[Means for solving problems]

In order to solve the above problem, the present invention provides a curved arm on the back surface of the fuel filler lid that extends from the end of the fuel filler lid toward the outside of the lid surface, and attaches the tip of this arm to the vehicle body. In the hinge structure of the fuel filler lid that is hinged, the arm of the fuel filler lid is housed in the hinge, and the arm has a wall surface adjacent to it in the closed state and is fixed to the vehicle body side member. A bag-shaped hinge cover is provided, and a mounting engagement portion that engages with the tip of the arm is formed, and the mounting and engagement portion is engaged with the tip of the arm to fuse the arm between the hinge cover and the arm. A spring is provided to bias the Elfiller lid in the opening direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the structure of a hinge portion of a fuel filler lid according to the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the hinge structure of a fuel filler lid according to the present invention. In this embodiment, the fuel filler lid 10 is made of resin, and as in the conventional case, a curved arm 11 extending from the end of the fuel filler lid toward the outside of the lid surface is provided on the back surface of the fuel filler lid. It is formed integrally with the Elfilarrid 10.

On the other hand, on the vehicle body side, a base 13 supports a fuel filler neck (not shown) at the opening of the fender 12 that is closed by the fuel filler lid 10.
is installed. This base 13 is the bottom wall 1
3a and a side wall 13b, and an opening is provided on one side of the side wall 13b. This opening has a hinge formed from an annular flange portion 14a that is attached to the side wall with screws 16, and a substantially bag-shaped cover portion 14b with an open upper end that is inserted from the flange portion 14a into the opening of the side wall 13b. A cover 14 is provided.
This hinge cover 14 has a shape that does not hinder the movement of the arm 11 when the fuel filler lid 10 is opened and closed, and in particular,
It has a shape that substantially matches the arm 11 in the closed state and has a wall surface to which the arm approaches in the closed state. The end of the arm 11 is pivotally supported within the hinge cover 14, and a plate-shaped spring 15 is wound around the pivotally supported end of the arm. As shown in FIG. 4, the spring 15 is a metal member formed by bending a plate material roughly following the shape of the end of the arm 11.
1, and a spring portion 15b extending along the outside of the arm 11 from the mounting portion 15a. Spring part 15
b, the center part 15c is cut and raised and extends in the direction away from the arm, while both end parts 15d are formed in contact with the outside of the arm 11, and the center part 1
Arm 1 due to the repulsive force between 5c and both ends 15d.
This obtains a biasing force of 1. In addition, code 1 in Figure 3
7 is a cover member that covers the end of the cover portion 14b.

Therefore, according to this embodiment, during assembly, as shown in FIG.
into the end of arm 11, and then
1 into the cover part 14b of the hinge cover 14, passing a shaft (not shown) through the tip of the arm, and then attaching the cover member 17. When the fuel filler lid 10 is closed after assembly, as shown in FIG.
is sandwiched between the arm 11 and the hinge cover 14, and the center portion 15c of the spring portion 15b abuts against the hinge cover 14 and bends, and its restoring force causes the arm 1 to
1 in the direction to open the fuel filler lid.
This biasing force is maximum when the fuel filler lid is in the closed state, and continues to apply the biasing force to the arm 11 until the fuel filler lid 10 is in the initial open state.

〔Effect of the invention〕

As explained above, according to the present invention, a curved arm extending from the end of the fuel filler lid toward the outside of the lid surface is provided on the back surface of the fuel filler lid, and the tip of this arm is hinged to the vehicle body. In the hinge part structure of the fuel filler lid, the arm of the fuel filler lid is housed in the hinge part, and has a wall surface to which the arm approaches in the closed state, and a bag-like structure fixed to the vehicle body side member. A hinge cover is provided, a mounting engagement portion is formed that engages with the tip of the arm, and the mounting engagement portion is engaged with the tip of the arm to fuel the arm between the hinge cover and the arm. Since a spring is provided that biases the door in the opening direction, when assembling the hinge device, all you have to do is engage the spring's mounting engagement part with the arm tip, attach it, insert it into the hinge case, and pivot it. ,
The hinge portion of the fuel filler lid can be assembled extremely easily with one touch, resulting in an effect that costs can be reduced.
