Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing mechanism for a fuel filler lid of an automobile.

A fuel filler lid (hereinafter simply referred to as a lid) of an automobile is normally rotatably attached to an opening formed in a rear fender via a hinge mechanism. In addition, this lid must be installed so that the lid surface is aligned with the rear fender surface when the lid is closed, so as not to spoil the appearance of the vehicle body. For this reason,
The center of rotation of the hinge is inside the opening, and as a result, when the lid is opened, the outer edge of the lid on the hinge side interferes with the edge of the opening, damaging both painted surfaces and causing rust. There was a problem. In addition, since the lid is rotatably mounted in the opening in alignment with the rear fender surface, it is necessary to provide a relatively large gap between the two to avoid interference between the lid periphery and the opening periphery when the lid is opened and closed. There was also the problem that this gap stood out as a parting line and spoiled the appearance.

Incidentally, references include those shown in the specification of Japanese Utility Model Application No. 16789/1983.

In view of such conventional problems, the present invention eliminates any interference between the lid and the periphery of the opening when the lid is opened and closed.
Another object of the present invention is to provide an opening/closing mechanism that can minimize the gap between the lid periphery and the opening periphery to provide a sense of unity between the lid and the fender.

In order to achieve the above object, in the present invention, a support shaft is provided protruding from the back of the reed at a position offset from the center of the lid, and at the same time, this support shaft is held on the vehicle body side, and the support shaft is held in the lid closed position. A locking mechanism is arranged to fix the lid and release the fixation of the support shaft by operating an opener, pushing the support shaft outward together with the lid, and allowing rotation of the lid about the support shaft. When opening the lid, the lid is first raised from the rear fender surface and then rotated to open the opening.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In FIGS. 1 to 6, 1 is a rear fender, 2 is an opening in which the inlet of a fuel filler tube 3 is provided in the inner depth, and 4 is a lid disposed in the opening 2. It is fixed to a filler base 5 fixed to the back side periphery of the opening 2.

A support shaft 6 is integrally provided on the back side of the lid 4 at a position offset from the center of the lid 4 to one side, for example, to the rear side. On the circumferential side of this support shaft 6, there is a lock groove 7 that engages with a push rod 15 of a lock mechanism 12, which will be described later, when the lid 4 is aligned with the fender 1 surface and closed, and a guide groove following this lock groove. 8 is formed. This guide groove 8 consists of a first groove 8a that extends in the axial direction toward the shaft tip side following the lock groove 7, and a second groove 8b that extends perpendicularly in the circumferential direction from the toe of this first groove 8a. . The first groove 8a is formed to a length that allows the support shaft 6 to slide relative to the push rod 15 with an appropriate stroke that completely lifts the lid 4 above the surface of the rear fender 1 from the closed position of the lid 4. On the other hand, the second groove 8b holds the lid 4 against the support shaft 6.
clockwise in Figure 6 from the position where it slides outward.
It has a length that allows it to rotate 180 degrees. Further, a protrusion 9 is formed at the bottom of the boundary between the lock groove 7 and the first groove 8a to partition the bottoms of these two grooves. This protrusion 9 is formed lower than the depth of the groove, and has an oblique guide surface 9 on the side surface on the first groove side.
A is formed. Further, at the groove bottom of the second groove 8b, a push rod 15 is engaged with the toes on both sides of the second groove 8b, and holds the position, and gives a sense of moderation to the rotation of the support shaft 6. small protrusion 10,
11 is formed.

Reference numeral 12 indicates a lock mechanism fixed to the vehicle body side, specifically, to the filler base 5 in correspondence with the support shaft 6. This lock mechanism 12 includes a casing 13 that accommodates the support shaft 6 so as to be slidable and rotatable in the axial direction, a spring 14 that urges the support shaft 6 outward together with the lid 4, and a vehicle interior operating lever (not shown) and a Bowden cable. a push rod 15 that unlocks the support shaft 6 by operating an opener 16 consisting of a push rod 17;
It is roughly composed of.

The casing 13 is inserted into a mounting hole 5a formed in the filler base 5 and fixed to the filler base 5 with a clip 18, and a mounting hole 5 is provided between the tip flange 13a and the filler base 5.
A sealing material 19 is interposed to seal part a. The spring 14 is elastically loaded between the rear end of the casing 13 and the end of the support shaft 6, and always urges the support shaft 6 outward. The push rod 15 is attached to a holder 20 integrally formed on the side surface of the casing 13.
A built-in spring (not shown) urges it inwardly into the casing 13 so that it protrudes into the casing 13 and engages with the lock groove 7 and guide groove 8 of the support shaft 6. In addition, 21 in the figure shows the knob of the lid 4.

According to the structure of the above embodiment, when the lid 4 is aligned with the rear fender 1 surface and closed, the tip of the push rod 15 comes into contact with the bottom of the lock groove 7 due to the set spring force built into the holder 20, and Due to the force of the spring 14, the protrusion 9 engages with the push rod 15 and restrains the support shaft 6, thereby reliably locking the support shaft 6, that is, reliably locking the lid 4.

When the push rod 15 is pulled up via the Bowden cable 17 by operating the opener 16 until its tip exceeds the protrusion 9, the spring 1
4, the support shaft 6 slides together with the lid 4 toward the outside in the axial direction guided by the first groove 8a and the push rod 15, and the lid 4 rises above the surface of the rear fender 1. In this state, Lid 4
When the lid 4 is rotated clockwise in FIG. 6, the lid 4 is guided and regulated by the second groove 8b and the push rod 15, and rotates around the support shaft 6. When the lid 4 is rotated 180 degrees, the tip of the push rod 15 meets the protrusion 11 and the groove. 8b
It is possible to maintain the opening degree of the lid 4 by engaging with the toe of the lid 4, and to open the opening 2 with a sufficient area that does not interfere with the fuel injection operation.

Next, when closing the lid 4 after injecting fuel, the above-mentioned operation can be reversed. After rotating the lid 4 180 degrees in the opposite direction,
When pushed against the force, the guide surface 9a of the protrusion 9 pushes up the push rod 15 once, and the protrusion 9 climbs over the tip of the push rod 15.
The tip of the push rod 15 sinks into the bottom of the lock groove 7, and the support shaft 6, that is, the lid 4 can be reliably locked.

Here, when the lid 4 is rotated, the second groove 8
The protrusions 10 and 11 at the bottom of the groove b are the push rods 15.
A sense of moderation can be obtained when passing over the tip, and it can be easily determined that the lid 4 has been rotated to the proper position.

Although the above-mentioned embodiment discloses the case where the lid is attached to the rear fender, the present invention can be similarly applied to the case where the lid is attached to the rear panel above the trunk lid.

As described above, according to the present invention, when the lid is opened, the lid is raised above the vehicle body panel surface and then the lid is rotated to open the opening, so that the lid and the vehicle body panel surface are connected to each other. There is no interference,
Therefore, it is possible to avoid causing rust to occur due to damage to the painted surface due to the interference. Furthermore, even if the lid area is made close to the opening area, there is no interference between the lid periphery and the opening periphery when the lid is opened or closed, so the gap between the lid periphery and the opening periphery can be minimized. It has great practical effects, such as making parting lines less noticeable and improving the appearance.
