Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a fuel lid that is attached to the body of an automobile and that swings to open and close an opening into which a fuel replenishment gun is inserted. We have improved the hinge pin and the arm connected to the hinge pin to be attached to the body side during automobile assembly, so that the fuel lid does not open or close involuntarily, and when a person opens or closes it, the arm provides sufficient rotational resistance so that it can be opened at any desired angle. To provide a fuel lid which can be stopped at a position where the hinge pin is rotatably wound and in particular handles a bulge in a crimping leg of an arm rotatably wrapped around a hinge pin to prevent the pin from coming into contact with the inner surface. be.

(Prior Art) A conventional structure for attaching a resin fuel lid to an automobile body is disclosed as a conventional structure in Japanese Utility Model Application Publication No. 55-5322, and is also shown in the attached drawings of this application, but the inner surface of the fuel lid is There is no disclosure of a system in which a crank part is provided on both sides of the hinge pin in contact with the fuel lid, and each end of the crank part is supported on the inner surface of the fuel lid, or the hinge pin is pressed against the inner surface from above.

Here, FIGS. 9 to 11 show representative examples of the type using the hinge pin which is the basis of the improvement according to the present invention.

In the examples in Figures 9 to 11, both ends of the hinge pin a are crank-shaped, bent pieces c and c attached to the body side are formed on the hinge pin a to protrude at almost right angles, and a shaft protrudes above and below the inner surface of the fuel lid body b. Fit the ends of the crank portions b at both ends of the hinge pin a into the insertion holes f of the branch pieces e, and insert the bent pieces c into the eleventh
As shown in the figure, it is attached to the body h by a screw g, and when the fuel lid main body d swings open and close, a small rotational resistance acts due to the elasticity of the long rising portion of the crank part b against the side surface of the shaft support piece e. Therefore, involuntary rocking opening/closing cannot be sufficiently prevented, and even if the opening angle is manually stopped at an arbitrary opening angle, only a small amount of rotational resistance will be applied as mentioned above, so the opening and closing of the involuntary rocking movement will not be sufficiently prevented. It is not possible to maintain the above-mentioned arbitrary opening angle, and there is a drawback that reliability is lacking. Note that there is no literature on the structures shown in FIGS. 9 to 11, but they have actually been implemented.

(Problems to be Solved by the Invention) As stated in the previous section, the conventional fuel lid does not have strong rotational resistance when opening and closing. However, it is normal to move the paint line and apply the paint after the fuel lid body is assembled to the body of an automobile, etc. In that case, the fuel lid body is rotated at a 30° angle.
It must be opened at an arbitrary angle of ~50° so that the sprayed paint adheres to the inner surface as well. However, if the rotational resistance is not strong, the fuel lid body will close involuntarily due to the spray pressure of the paint, resulting in a defective coating that cannot be painted on the inside.
It must be thoroughly inspected after painting, and if the rotational resistance of the fuel lid body is not strong enough while being driven on the road, it is likely to shake due to vibration and generate unpleasant noise.

The object of the present invention is to provide a fuel lid that can solve these problems, and in particular, increases rotational resistance and solves the problems associated with it.

(Means for Solving the Problems) The fuel lid of the present invention has a structure that solves the above problems, and has a pair of insertion holes provided on the inner surface of the synthetic resin fuel lid main body at the top and bottom of the vehicle body, and a pair of insertion holes provided at the top and bottom of the vehicle body. a hinge pin that contacts the inner surface and has a crank portion that includes a main body extending in the direction of the main body, a rising leg extending perpendicularly to the main body, and an end extending in the vertical direction of the vehicle body and inserted into the insertion hole; a rib provided on the inner surface of the fuel lid body, which engages with a side surface of the rising leg of the hinge pin to restrict vertical movement of the vehicle body of the hinge pin with respect to the fuel lid body; and a retaining piece that presses the hinge pin against the inner surface. , an arm having one end attached to the vehicle body side and the other end having a caulking leg rotatably wrapped around a hinge pin, the inner surface having a lower surface around which the caulking leg is wrapped. It is characterized by having a recessed groove formed therein.

(Embodiment) Fig. 1 illustrates an embodiment of the present invention, in which the shaft support pieces shown in Figs. 3, 3, a groove 6 into which both ends of the hinge pin 11 fit when the ribs 5, 5 and the crank portions 12, 12 at both ends of the hinge pin 11 are brought down until they contact the inner surface 2, and a retaining piece to be described later. three protrusions 8a each forming the groove 7 into which one leg of the 15 is fitted;
8b, 8c, and the inner surface 2 on each inside of the grooves 6, 6.
A pair of recessed grooves 9 and a recessed groove 9 are integrally molded, and the vertical insertion holes 4,
4 is formed.

As shown in FIGS. 1 and 2, the hinge pin 11 has short upright legs 13, 13 on both sides of the main body and end portions 14, 14 at both ends to form clamp parts 12, 12. Since it is short, it has almost no elasticity to expand or contract in the axial direction. Therefore, the end portion 14 of one crank portion 12 is moved along the arrow a in FIG.
3, and then pass the other end 14 in the direction of the arrow b in FIG. 13, 13 are fitted so as to substantially contact the ribs 5, 5 of the inner surface 2, and the hinge pin 11 is fitted into the grooves 6, 6. The ribs 5, 5 make it impossible for the hinge pin 11 to move in the axial direction when the pin 11 is folded down as described above (see FIG. 13).

After assembling the hinge pin 11 by bringing it into contact with the inner surface 2 and folding it down as described above, as shown in FIG. A fixing piece 15 is attached to the inner surface 2 by welding or gluing, and has a leg 16 that fits between the edges 1' bent toward the inner surface of the groove 1 and a leg 17 that fits in the groove 7. The retaining piece 15 holds down the main body of the hinge pin 11 and the ends 14 of the crank parts 12, 12 of the pin 11,
This is a member that makes rotation around 14 impossible.

The arm 21, which is to be attached to the body side, has a right-angled end 22 and is bent into a substantially U shape with caulking legs 23, 23 corresponding to the recessed grooves 9, 9 formed on the inner surface 2. , its caulking leg 23
Wrap it around the body of the hinge pin 11 as shown in Figure 5,
A caulking 24 is applied around the hinge pin 11,
A hammering force 25 as shown in FIG. 6 is applied to a part of the caulking 24.

The lower surfaces of the caulking legs 23, 23 that surround the hinge pin 11 are fitted into the recessed grooves 9, 9 as shown in FIG. 7, so as not to prevent the hinge pin 11 from contacting the inner surface of the main body. do.

Figure 7 shows the opening motion of approximately 100° relative to the body of an automobile or the like.

FIG. 8 shows the mounting position of the fuel lid main body 1 on the body of an automobile or the like.

(Operations and Effects of the Invention) The fuel lid of the present invention has an end portion of a crank portion formed at both ends of the hinge pin body in a pair of insertion holes provided on the inner surface of the synthetic resin fuel lid body at the top and bottom when viewed from the vehicle body to which the fuel lid is attached. At the same time, a rib is provided on the inner surface that engages with the rising leg of the crank part when the hinge pin is in a folded state, and a retaining piece is attached to the inner surface from above the hinge pin, The caulking legs of the arm attached to the body side are rotatably wound and caulked together, and a recessed groove is formed on the inner surface into which the connecting lower surface of the wound caulking is inserted. In addition to being determined by the degree of winding and crimping of the crimping leg 23, the hinge pin 11
Since the connecting lower surface of the caulked leg 23 is fitted into the recessed groove 9 formed on the inner surface 2, the hinge pin 11 forming the shaft of the arm 21 can be fixed close to the inner surface 2. This has the advantage that the radius of rotation of the main body 1 can be minimized.
