DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a fuel lid on an automobile, and more particularly to a structure for preventing rattling of the fuel lid.

[0002]

2. Description of the Related Art A fuel lid is a hinged door that opens and closes an inlet to a fuel tank in an automobile. The fuel lid is disposed in parallel with a vehicle body side surface and opens and closes by raising and lowering in a horizontal orthogonal direction from the vehicle body side surface. Most of them are known to open and close in such a way as to undulate in an obliquely downward orthogonal direction from the side of the vehicle body.

[0003] When the fuel lid opens and closes obliquely downwardly from the side of the vehicle body, the fuel lid once opened is maintained under its own weight and is kept in an open state without being closed carelessly. Can not. This eliminates the need for the operator of the stand to reopen the fuel lid once opened, for example, during fuel injection.

Since the hinge shaft of such a fuel lid must be supported obliquely with respect to the vehicle body side bracket, as shown in FIG. 8, both ends of the hinge shaft 30 are attached to a fuel lid bracket 2 for fixing the fuel lid 1. A pair of upper and lower pivots 4, 4 having parallel oblique bearing surfaces 4a, 5a for supporting.
5 are formed apart from each other, and both ends of the hinge shaft 30 are bent obliquely parallel to each other in a Z-shape and crushed on the upper and lower pivots 4, 5 to form flat portions 31, 32,
The flat portions 31, 32 are joined to the bearing surfaces 4a, 5a by contact welding.

[0005] The fuel lid 1 forming a part of the side surface of the vehicle body by attaching the winding portion 13 of the vehicle body side bracket 12 to the hinge shaft 30 fixed to the fuel lid bracket 2 in this manner is attached.

[0006]

However, in such a fuel lid that opens and closes obliquely downward from the side of the vehicle body, the problem of welding position deviation of the hinge shaft and the consistency between the bracket and the hinge shaft on the vehicle body side are solved. An error causes backlash during opening / closing or running the vehicle (inconsistency)
However, there is a problem that vibration noise is easily generated.

For this reason, the hinge shaft 30 is not welded to the bearing surfaces 4a and 5a of the pivots 4 and 5, and the hinge shaft 3 is not processed at both ends as shown in FIG.
It is assumed that the winding portion 13 of the vehicle body-side bracket 12 is wound around the center portion of the vehicle body 3 and the winding portions 21 and 21 of the fuel lid bracket 2 are wound around the upper and lower end portions of the hinge shaft 33. It is practically difficult to wind the winding part 21 around the hinge shaft 33 because it is necessary to maintain a constant angle θ between the hinge shaft 33 and the hinge shaft 33.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the problem of backlash in a fuel lid that opens and closes obliquely downward from the side of the vehicle body.

[0009]

In order to achieve the above object, according to the present invention, a pair of bearing surfaces each having a through hole through which a hinge shaft is inserted are provided on a fuel lid bracket for fixing a fuel lid. The upper and lower pivots are formed integrally with each other or attached separately as inclined parallel to each other, and a hinge shaft is inserted from the through hole of the upper pivot into the through hole of the lower pivot to prevent the hinge shaft from coming off. A fuel lid mounting structure characterized in that a vehicle body side bracket is engaged with a shaft.

[0010] Thus, the hinge shaft is easily assembled and fixed to the fuel lid bracket and the vehicle body-side bracket without any play without relying on welding, so that the workability of mounting the fuel lid on the vehicle body is improved, and the quality of mounting the fuel lid on the vehicle body is improved. .

According to the second aspect of the present invention, a hinge shaft winding operation is required by mounting a tubular portion through which the hinge shaft is inserted into the hinge shaft winding portion of the vehicle body side bracket in advance. In addition, the mounting workability can be improved, and the clearance between the hinge shaft and the cylindrical portion can be made as small as possible to reduce backlash.

Further, as set forth in claim 3, the upper and lower pivots separately mounted on the fuel lid bracket include:
If a through hole for inserting a hinge shaft is provided at one end of the plate body having an oblong cross-section, and a rivet hole corresponding to a rivet hole opened in the fuel lid bracket is provided at the other end, a fuel lid bracket is provided. In addition, since a complicated mold can be omitted and a simple mold can be omitted without press-molding the lower pivot portion, the cost of the fuel lid bracket can be reduced.

According to a fourth aspect of the present invention, a positioning projection is formed on a bent portion of the plate, and a positioning recess to be engaged with the positioning projection is formed on the fuel lid bracket. The Axis can be accurately assembled to the fuel lid bracket as designed.

The hinge shaft may be a rod having a large diameter portion at one end or a rod having no large diameter portion at both ends and a push nut attached to one end. By adopting it, the cost of the hinge shaft can be reduced and workability can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a fuel lid 1 made of a metal or resin plate of a type that opens and closes obliquely downward from the side of the vehicle body, FIG. 2 is a side view thereof, and FIG. 3 is a perspective view of a main part of FIG. As shown, an upper pivot 4 and a lower pivot 5 for attaching a hinge shaft 3 to a fuel lid bracket 2 fixed to the back of the fuel lid 1.
However, the bearing surfaces 4a and 5a are arranged in parallel with each other and in a straight line in the vertical direction by the conventional design and processing.

Through holes 6, through which the hinge shaft 3 can pass, are formed in the bearing surfaces 4 a, 5 a of the upper and lower pivot portions 4, 5 which are parallel to each other.
7 are respectively set on the same center line. When the hinge shaft 3 is inserted into the through holes 6 and 7, the hinge shaft 3 is disposed obliquely by a predetermined angle θ with respect to the side surface of the vehicle body.

On the other hand, as shown in FIG. 4A, the hinge shaft 3 inserted into the through holes 6 and 7 has a rod 8 having a large-diameter portion 8a formed by crushing one end of the hinge shaft 3, and FIG. As shown, a rod 9 having a large-diameter portion 9a whose one end is flattened or a rod 10 having no large-diameter portion at both ends as shown in FIG. 4C. The rods 8 and 9 do not fall out if they are inserted into the through holes 6 of the upper shaft part 4.
For 0, push nut 1 at upper end as retaining
1 can be fitted. Similar push nuts 11 can be fitted to the lower ends of the rods 8, 9, 10 inserted through the through holes 6, 7, or the ends can be crushed to prevent the rods 8, 9, 10 from coming off.

Therefore, the fuel lid bracket 2 and the hinge shaft 3 are integrated by inserting the hinge shaft 3 into the through holes 6, 7 of the upper and lower pivot portions 4, 5 of the fuel lid bracket 2 to prevent the lower end thereof from coming off. The hinge shaft 3 is attached to the vehicle body side bracket 12.
When the hinge shaft winding portion 13 is wound, the hinge is completed, so that the conventional welding process is not required, and the mounting operation is simplified.

As shown in FIG. 5, the hinge shaft 3
Spot welding 1 by centering the cylindrical portion 14 for inserting
If it is installed in advance at 5, the upper part of the fuel lid bracket 2 is aligned with the through-holes 6 and 7 of the lower pivots 4 and 5, and then the hinge shaft 3 is moved from the through-hole 6 through the cylindrical part 14 to the hinge shaft 3. By attaching the fuel lid 1 to the vehicle body by inserting the fuel lid 1 into the through hole 7 and stopping the lower end of the hinge shaft 3, the workability is good.

As a result, the hinge shaft 3 can be disposed as designed on the precisely machined parallel bearing surfaces 4a, 5a through the through holes 6, 7 which are precisely opened. Even if the hinge shaft 3 is assembled to the vehicle body side bracket 12, no backlash occurs.

As shown in FIG. 6, the upper and lower pivot portions 4 and 5 are manufactured as separate parts from the fuel lid bracket 2 and are attached to the fuel lid bracket 2 simply and accurately by using rivets or the like. You may do so. That is, a pair of pivot members 40, 40 each formed of a plate having an elliptical cross section are fixed to the upper and lower inner peripheral edges of the fuel lid bracket 2a in the form of a frame in a point symmetric arrangement.

A through hole 41 through which the hinge shaft 3 is inserted is formed at one end of the pivot member 40, and a rivet insertion hole 42 is formed at the other end. Therefore, if the rivet insertion hole 43 corresponding to the rivet insertion hole 42 is opened in the fuel lid bracket 2a, when the rivet 44 is driven by aligning the rivet insertion holes 42, 43, a bent portion having an elliptical cross section is formed. Since the pivot member 40 can be accurately fixed to the fuel lid bracket 2a without swinging in contact with the inner peripheral edge of the frame, the hinge shaft 3 is accurately assembled.

In this example, in order to ensure that the upper and lower pivot members 4 and 5 are accurately assembled, a positioning projection 45 is integrally formed on one side of the pivot member 40 as shown in FIG. Then, a positioning concave portion 46 with which the positioning convex portion 45 is engaged is formed in the fuel lid bracket 2a. The shape of the positioning projection 45 is preferably a polygon as illustrated, but is not limited thereto. Positioning convex part 4
When 5 is formed by press molding, the rigidity of the pivot member 40 increases.

Thus, since the hinge shaft 3 is accurately assembled to the fuel lid brackets 2 and 2a as designed, unlike the conventional fixing by welding, the assembly can be performed without looseness, and when the fuel lid 1 is opened and closed or when the vehicle is opened or closed. The occurrence of play during traveling is eliminated.
