Description

  The present invention relates to a fuel lid structure.

Conventionally, various fuel lid structures have been proposed (for example, Patent Document 1). FIG. 8 shows one of them.
In this example, the fuel lid 119 can rotate relative to the vehicle body 110 between an open position where the recess 111 is opened and a closed position where the recess 111 is closed. The fuel lid 119 is always subjected to a rotational biasing force toward the open position. Further, a metal striker 121 is fixed to the inner surface of the fuel lid 119 (the surface facing the recess 111). The striker 121 includes a convex pushing portion 123 and a pin receiving portion 124 adjacent to the pushing portion 123.

On the other hand, a metal lock pin 127 is slidably supported on the inner surface (surface) of the recess 111. The lock pin 127 is slidable in the approaching direction toward the striker 121 side of the fuel lid 119 (located in the closed position) and in the separating direction away from the striker 121. Further, the lock pin 127 is always urged in the approaching direction by the urging means.
Furthermore, the vehicle body 110 is provided with a lock release means (not shown) that slides the lock pin 127 in the separating direction against the urging force of the urging means.

When the pushing portion 123 of the striker 121 is engaged with the outer peripheral surface (a part) of the lock pin 127 from the vehicle inner side when the fuel lid 119 is located at the closed position, the fuel lid 119 is moved by the lock pin 127 and the pushing portion 123. It is held in the closed position (see FIG. 8).
On the other hand, when an occupant or the like of the vehicle operates the unlocking means in this state, the lock pin 127 slides in the separating direction. As a result, the engagement between the lock pin 127 and the push-in portion 123 is released, so that the fuel lid 119 is rotated to the open position side by the rotation biasing force. Therefore, an occupant or the like can supply vehicle fuel to the oil supply portion 112 provided in the recess 111.

  When the passenger lid 119 rotates to the closed position side when an occupant or the like is in the open position, the pushing portion 123 of the striker 121 is locked when the fuel lid 119 reaches a predetermined position (intermediate position) between the open position and the closed position. The tip of the pin 127 comes into contact, and the lock pin 127 is slid in the separating direction (inside the vehicle body).

  When the fuel lid 119 reaches the closed position, the engagement state between the pushing portion 123 of the striker 121 and the lock pin 127 (the tip thereof) is released. Then, the lock pin 127 protrudes vigorously in the approaching direction by the urging force of the urging means, and the tip of the lock pin 127 comes into contact with the pin receiving portion 124 of the striker 121. Further, since the pushing portion 123 of the striker 121 is engaged again with (a part of) the outer peripheral surface of the lock pin 127, the fuel lid 119 is again held in the closed position.

Japanese Patent Application No. 2014-058284

In the conventional fuel lid structure, both the striker 121 on the fuel lid side and the lock pin 127 on the vehicle body side are made of metal.
Therefore, when the fuel lid 119 is rotated to the closed position and the lock pin 127 collides with the pin receiving portion 124 of the striker 121 by the urging force of the urging means, an unpleasant sound (between the striker 121 and the lock pin 127 ( There was a risk of metal sound).

  The present invention has been made to address the above problems. That is, one of the objects of the present invention is to provide a fuel lid structure in which an unpleasant sound is not generated when the fuel lid is closed.

In a fuel lid structure comprising
The present invention is applied to a structure in which at least one of the collision part and the pin receiving part is made of an elastic body.

  According to this, an unpleasant sound is not generated when the collision portion comes into contact with the pin receiving portion by closing the fuel lid.

  Other objects, other features and attendant advantages of the present invention will be readily understood from the description of the embodiments of the present invention described with reference to the following drawings.

It is the perspective view which looked at a part of side surface of the vehicle carrying the fuel lid structure which concerns on embodiment of this invention from the side. It is sectional drawing of the vehicle body cut | disconnected along the II-II arrow line of FIG. It is an enlarged bottom view of a lock pin. It is a figure which shows the lock pin when it sees in the IV arrow line direction of FIG. FIG. 3 is a cross-sectional view similar to FIG. 2 when the fuel lid is moved in the closing direction from the position of FIGS. 1 and 2. FIG. 6 is a cross-sectional view similar to FIG. 2 when the fuel lid is further moved in the closing direction from the position of FIG. 5. FIG. 3 is a cross-sectional view similar to FIG. 2 when the fuel lid has reached the closed position. It is sectional drawing similar to FIG. 7 of a prior art example.

  Hereinafter, a fuel lid structure according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  A recess 11 for refueling is formed in a rear portion of the side surface of the vehicle body 10 (the portion disclosed in FIG. 1, a portion located behind the door provided on the side surface of the vehicle body 10). Further, an oil supply portion 12 is provided inside the recess 11. The oil supply portion 12 is a cylindrical body having an open end, and communicates with a fuel tank (not shown) provided inside the vehicle body 10. A cap 13 is detachably attached to the tip opening of the oil filler 12. Therefore, if the cap 13 is removed from the fuel supply unit 12, vehicle fuel can be supplied to the fuel tank through the fuel supply unit 12.

One end of a hinge 15 is fixed to the inner peripheral edge of the recess 11 so as to be rotatable around a vertical rotation axis of the vehicle body. Further, a fuel lid 19 is fixed to the other end of the hinge 15.
The fuel lid 19 includes a lid body 20 and a striker 21.
The lid body 20 is made of metal, and its outer shape is substantially the same as that of the recess 11. The other end of the hinge 15 is fixed to the inner surface of the lid body 20 (the surface facing the recess 11). Therefore, the lid main body 20 can rotate relative to the vehicle body 10 (concave portion 11) around the rotation axis of the hinge 15. Specifically, it can rotate between an open position where the recess 11 is completely opened (the position of the phantom line in FIG. 2) and a closed position where the recess 11 is completely closed (FIG. 7).
Further, a rotation urging means (not shown) that urges the hinge 15 to rotate in one direction is provided between the vehicle body 10 and the hinge 15. Therefore, when no urging force other than the rotation urging means is applied to the lid body 20, the lid body 20 is held in the open position by the urging force of the rotation urging means (however, the lid body 20 is in the closed position). Except when to do).

A part of the striker 21 is fixed to the inner surface of the lid body 20 (the surface facing the recess 11).
The striker 21 is manufactured by bending a metal plate. Therefore, the striker 21 can be elastically deformed.
A pressing piece 22 is formed at the tip of the striker 21 (the end opposite to the end on the fixed side with respect to the lid body 20). In a portion adjacent to the pressing piece 22 of the striker 21, a pressing portion 23 made of a convex portion is formed. Further, a pin receiving portion 24 is formed at a portion adjacent to the pushing portion 23 of the striker 21.

  A pin support member 25 (which constitutes a part of the vehicle body 10) projects in a fixed state on a part of the inner peripheral surface of the recess 11. A slide support hole (not shown) extends along the longitudinal direction of the vehicle (the left and right direction in FIGS. 2 and 5 to 7) on the front end surface (left end surface in FIGS. 2 and 5 to 7) of the pin support member 25. ) Is formed. A part of the lock pin 27 is slidably inserted into the slide support hole.

The lock pin 27 includes a pin main body 28 extending in a direction parallel to the slide support hole, and a cushion 30 (collision portion) fixed to the tip of the pin main body 28.
The pin body 28 is made of hard plastic, and the distal end portion thereof constitutes a lock portion 29 having a smaller diameter than the proximal end portion.
The cushion 30 is made of an elastic body (for example, an elastomer), and its planar shape is substantially T-shaped (see FIG. 3), and its side shape (shape when viewed from the side of the vehicle body 10) is substantially linear ( (See FIG. 4).
The pin body 28 and the cushion 30 are simultaneously molded by using two-color molding. As shown in the figure, the cushion 30 is embedded in the pin main body 28 and integrated with the pin main body 28 except for the contact portion 30a which is the tip. The contact part 30a protrudes outward from the maximum protrusion part 28a which is the most traveled part (the part located on the leftmost side in FIGS. 3 and 4) in the tip part of the pin body 28.

  The lock pin 27 is located in the approach direction (left direction in FIGS. 2 and 5 to 7), which is the direction approaching the striker 21 of the fuel lid 19 (located in the closed position), and in the separation direction (direction left from the striker 21). 2 and FIG. 5 to FIG. 7 are slidable in the right direction). More specifically, the maximum protrusion position (the position shown in FIG. 2) where the protrusion amount from the pin support member 25 is the maximum, and the minimum protrusion position (not shown; the position shown in FIG. 6) where the protrusion amount is the minimum. Further, it is possible to slide between a position where the protruding amount is small).

Further, the slide support hole of the pin support member 25 is provided with an urging means 32 for urging and moving the lock pin 27 toward the maximum projecting position (see FIG. 2). This urging means 32 is constituted by a compression coil spring. Therefore, when no external force other than the urging means 32 is applied to the lock pin 27, the lock pin 27 is located at the maximum protruding position.
Further, an open switch (not shown) linked to the lock pin 27 is provided near the driver's seat in the vehicle. When the open switch is not operated (when positioned at the initial position), the lock pin 27 is positioned at the maximum projecting position by the biasing force of the biasing means 32. On the other hand, when the open switch is operated, the lock pin 27 slides to the minimum protruding position against the urging force of the urging means 32.

  Next, the opening / closing operation of the lid main body 20 (fuel lid 19) will be described.

If the open switch is not operated when the lid body 20 is located at the closed position (when it is located at the initial position), as shown in FIG. The pushing portion 23 side is engaged from the vehicle inner side (lower side in FIG. 7). Accordingly, the lid body 20 is held in the closed position against the urging force of the rotation urging means. When the lid body 20 is located at the closed position, the occupant or the like cannot supply fuel to the fuel supply unit 12.
At this time, the pin receiving portion 24 of the striker 21 contacts the tip end portion of the lock pin 27, and the pin receiving portion 24 pushes the lock pin 27 toward the minimum protruding position. Therefore, the lock pin 27 is positioned slightly on the minimum protruding position side with respect to the maximum protruding position.

  When the occupant or the like operates the open switch when the lid body 20 is in the closed position, the lock pin 27 moves to the minimum protruding position against the urging force of the urging means 32. Then, the engagement between the lock part 29 of the pin main body 28 and the pushing part 23 of the striker 21 is released. Therefore, the lid body 20 automatically rotates to the open position by the urging force of the rotation urging means. When the lid main body 20 moves to the open position, the occupant or the like can supply fuel to the fuel supply unit 12.

In order to rotate the lid body 20 from the open position to the closed position, first, the open switch is returned to the initial position (the lock pin 27 is positioned at the maximum protruding position), and in this state, the lid body 20 is attached to the rotation urging means. Rotate to the closed position against the force. Then, when the lid body 20 reaches a predetermined position between the open position and the closed position (intermediate position shown in FIG. 5), the pressing piece 22 of the striker 21 contacts the pin body 28 of the lock pin 27 while being elastically deformed. To do.
At this time, since the pressing piece 22 presses the lock pin 27 in the direction of the arrow in FIG. 5, the lock pin 27 moves from the maximum protruding position toward the minimum protruding position.

When an occupant or the like further rotates the lid main body 20 from the position of FIG. 5 to the position of FIG. 6 (intermediate position), the pushing portion 23 of the striker 21 contacts the pin main body 28 of the lock pin 27 while being elastically deformed.
At this time, the push-in portion 23 pushes the lock pin 27 in the direction of the arrow in FIG. 5, so that the lock pin 27 moves further from the position in FIG. 5 toward the minimum protruding position.

When the occupant or the like further rotates the lid body 20 from the position shown in FIG. 6 and the lid body 20 reaches the closed position, the contact state between the pushing portion 23 of the striker 21 and the lock pin 27 (cushion 30) is released. Then, the lock pin 27 projects vigorously toward the maximum projecting position by the urging force of the urging means 32. When the vicinity of the maximum projecting position is reached, the contact portion 30a of the cushion 30 of the lock pin 27 collides with the pin receiving portion 24 of the striker 21 (see FIG. 7). However, since the cushion 30 is an elastic body, unpleasant sound (for example, metal sound) is not generated between the metal striker 21 and the cushion 30 at this time.
Further, as shown in FIG. 7, the pushing portion 23 of the striker 21 is engaged again with the lock portion 29 of the lock pin 27 (pin main body 28) from the vehicle inner side (lower side in FIG. 7). Accordingly, the lid body 20 is again held in the closed position.

In addition, this invention is not limited to the said embodiment, A various modified example is employable within the scope of the present invention.
For example, the cushion 30 may have a shape different from that illustrated, or may be formed of an elastic body different from the elastomer.
When the lid body 20 is rotated from the open position to the closed position, the pressing piece 22 or the pressing portion 23 of the striker 21 may be brought into contact with the cushion 30 (contact portion 30a).
The pin body 28 may be made of metal.
The lock pin 27 is composed only of the pin main body 28, the pin main body 28 is made of plastic or metal (the lock pin 27 is entirely made of plastic or metal), and the pin receiving portion 24 of the striker 21 (and the pressing piece 22). Alternatively, the portion corresponding to the pushing portion 23) may be formed of an elastic body (for example, an elastomer). Moreover, after providing the cushion 30 in the lock pin 27, you may comprise the site | part corresponding to the pin receiving part 24 (further, the pressing piece 22 and the pushing part 23) of the striker 21 with an elastic body.
