Description

The present invention relates to a lid opening / closing structure capable of opening / closing a lid that closes an opening provided in a vehicle body.

Conventionally, there is known a lid opening / closing structure for opening / closing a lid that closes an opening of a vehicle body provided with a fuel filler port or the like (for example, Patent Document 1). The lid opening / closing structure described in Patent Document 1 includes a box member, a driving member, an urging member, and a case member. The box member is attached to the opening of the vehicle body. The box member is recessed from the outer surface of the vehicle body toward the inside of the opening, and has a bottom portion with an open fuel filler port. The drive member is connected to the lid at the end in the outward direction of the opening. The drive member can slide and move in and out of the opening. The urging member is a spring extending in and out of the opening, and urges the driving member in the out-of-opening direction. The case member is fixed to the bottom of the box member. One end of the urging member is fixed to the case member. The other end of the urging member is fixed to the receiving portion of the driving member. The urging member is arranged adjacent to the driving member on the inner side of the opening.

In the lid opening / closing structure described above, in the closed state, the lid is locked to the closed position by the regulating member against the urging force of the urging member. Then, when the opening operation for opening the lid is performed, the lock of the lid is released, and the driving member slides and moves in the outward opening direction by the urging force of the urging member. When the driving member slides in the outward direction of the opening, the lid rotates around the center of rotation. Therefore, the lid can be released from the closed state by the opening operation.

Specifically, in the open state of the lid 20, the sensor protrusion 35 is pulled out from between the two terminals 71 and 72 of the through hole 54. In this case, the two terminals 71 and 72 are conducting with each other. On the other hand, in the closed state of the lid 20, the sensor protrusion 35 is inserted between the two terminals 71 and 72. In this case, the two terminals 71 and 72 are cut off from each other. The detection unit detects the opening and closing of the lid 20 based on the states of the two terminals 71 and 72.

Next, the operation of the lid opening / closing structure 1 will be described.

In the closed state, the lid 20 is locked to the closed position by a regulating member (not shown) against the urging force of the urging member 60 (state shown in FIG. 10). When a predetermined opening operation is performed by an operator such as a vehicle occupant in the closing lock of the lid body 20, the closing lock of the lid body 20 is released. When the closing lock of the lid 20 is released, the urging force of the urging member 60 is applied to the driving member 30, and the driving member 30 exerts the urging force on the bottomed base material 10 in the outward direction Xo of the vehicle body opening. Slide to move.

When the drive member 30 slides with respect to the bottomed base material 10 in the outward direction Xo of the vehicle body opening, the pressing force of the drive member 30 is applied to the lid 20, so that the pin portion 33 of the drive member 30 and the lid body The lid 20 rotates with respect to the drive member 30 about the second engaging portion 25 in a state where the first engaging portion 24 of the 20 is engaged. Further, in synchronization with the rotation of the lid 20 with respect to the drive member 30, the link member 40 and the second engaging portion 25 of the lid 20 are engaged, and the link member 40 and the bottomed base material 10 are engaged. The link member 40 rotates with respect to the bottomed base material 10 in a state of being engaged with the portion 19. During the opening operation of the lid 20, the rotation of the link member 40 with respect to the bottomed base material 10 increases the tilt angle of the link member 40 with respect to the base portion 13 of the bottomed base material 10, and the link member 40 moves inside and outside the vehicle body opening. It is performed so as to extend in the direction X. As a result, the lid 20 rotates with respect to the bottomed base material 10 and is opened (the state shown in FIG. 11).

Therefore, when a predetermined opening operation is performed by the operator in the closed state of the lid body 20, the driving member 30 is slid and moved in the outward direction Xo of the vehicle body opening with respect to the bottomed base material 10, and the lid body 20 is moved. It can be rotated to the open state side to open the open state (see FIG. 12). The rotation of the lid 20 to the open state side may be performed until the movement is restricted at a predetermined angle (for example, an angle of 100 ° from the closed state of the lid 20), and the movement is stopped by the movement restriction. Just do it.

When a predetermined closing operation is performed by the operator in the open state of the lid body 20, the lid body 20, the driving member 30, and the link member 40 operate in a process opposite to the above-described opening operation process. In this predetermined closing operation, the operator presses the surface side of the lid body 20 inward Xi of the vehicle body opening and exerts a force on the lid body 20 to rotate the lid body 20 toward the closed state side around the second engaging portion 25. It is to give. When this closing operation is performed, first, the lid 20 rotates about the second engaging portion 25 toward the closed state side with respect to the bottomed base material 10 against the urging force of the urging member 60. After that, the lid 20 and thus the driving member 30 slide and move inward Xi of the vehicle body opening with respect to the bottomed base material 10. Then, the lid 20 is in a closed state in which the lid 20 is locked to the closed position by the regulating member.

Therefore, in the open state of the lid body 20, the operator performs an operation of rotating the lid body 20 toward the closed state side with respect to the bottomed base material 10 and pressing the vehicle body opening inward Xi to lower the lid body 20. The lid 20 can be closed by rotating the drive member 30 toward the closed state and pushing the drive member 30 against the bottomed base material 10 inward Xi of the vehicle body opening (see FIG. 12).

As described above, according to the lid opening / closing structure 1, the driving member 30 is moved with respect to the bottomed base material 10 in the inward / outward direction X of the vehicle body opening by the urging force of the urging member 60 and the closing operation of the operator against the urging force. The lid 20 can be opened and closed by sliding the lid 20 to.

Further, in the lid opening / closing structure 1, the urging member 60 extends from the receiving portion 53 of the case member 50 and the main body portion 31 of the driving member 30 in the direction Y orthogonal to the inside / outside direction X of the vehicle body opening. It is arranged between the receiving portions 32b and both ends of the urging member 60 are fixed to both receiving portions 53 and 32b. That is, the axis of the vehicle body opening in which the urging member 60 extends and the axis of the vehicle body opening in which the driving member 30 slides to move are displaced in the direction Y orthogonal to the interior / exterior direction X of the vehicle body opening. Line up in a state.

In the configuration of the lid opening / closing structure 1, in order to apply the urging force of the urging member 60 to the lid 20 via the driving member 30, the urging member 60 and the driving member 30 are arranged in the inside / outside direction X of the vehicle body opening. It is not necessary to arrange the urging member 60 and the driving member 30 side by side in series, and it is sufficient to arrange the urging member 60 and the driving member 30 side by side in the direction Y orthogonal to the inside / outside direction X of the vehicle body opening. Therefore, the length of the vehicle body opening in the inside / outside direction X in the lid opening / closing structure 1 is shorter than the structure in which the urging members are arranged in series with respect to the drive member in the inside / outside direction X of the vehicle body opening. Is possible. Therefore, according to the lid opening / closing structure 1, it is possible to contribute to shortening the length of the vehicle body opening in the inner / outer direction X, and it is possible to make the overall configuration compact.

Further, in the lid opening / closing structure 1, the bottomed base material 10 has a base portion 13 having a two-tiered bottom surface, and the base portion 13 has two bottom surface portions, a first base portion 14 and a second base portion. Has 15. A through hole 15a through which the driving member 30 that slides in and out of the vehicle body opening X is provided is provided in the second base portion 15 located on the outer direction Xo side of the vehicle body opening with respect to the first base portion 14. ..

In the configuration of the lid opening / closing structure 1, the portion of the drive member 30 protruding inward Xi from the base portion 13 of the vehicle body opening is compared with the structure in which the bottomed base material 10 is not provided with the second base portion 15. The position of the end portion of the vehicle body opening in the inward direction Xi of the drive member 30 can be brought closer to the lid 20 while maintaining a certain length. Therefore, the length of the entire drive member 30 can be shortened while maintaining the function of the lid opening / closing structure 1, and the total length of the vehicle body opening in the lid opening / closing structure 1 in the inner / outer direction X can be shortened.

Further, the support point (specifically, the peripheral edge of the through hole 15a) of the bottomed base material 10 on which the drive member 30 is slidably supported can be brought close to the lid 20. Therefore, the distance from the peripheral edge of the through hole 15a to the lid 20 can be shortened, which makes it possible to prevent the drive member 30 from being displaced (rattling) in the sliding movement of the drive member 30. Stable slide movement can be ensured.

Further, the slide movement of the drive member 30 is performed in a state of penetrating the through hole 15a of the second base portion 15. The second base portion 15 is located on the outward Xo side of the vehicle body opening with respect to the first base portion 14. Therefore, it is possible to prevent water and dust that have entered the opening 11 from entering the space 17 through the through holes 15a and 15b formed in the second base portion 15, and the drive member caused by the water and dust can be suppressed. It is possible to reduce 30 slide defects. Further, in the space 17, the extending portion 32 is supported so as to be slidably contacted with the inner peripheral surface of the wall portion 18, and the extending portion 32 exists so as to divide the space 17. Therefore, even when water or dust enters the space 17, it is possible to prevent the water or dust from pouring into the terminals 71 and 72 provided on the case member 50. In order to increase the water suppression effect on the terminals 71 and 72, it is preferable to arrange the terminals 71 and 72 on the Xo side of the case member 50 in the outward direction of the vehicle body opening, and further, the vehicle body opening of the case member 50. It is more preferable to provide a drain hole at the end of the inward direction Xi side.

Further, the drive member 30 is supported so as to be slidably movable at two locations of the bottomed base material 10. Specifically, the drive member 30 is supported by the peripheral edge of the through hole 15a by the main body portion 31 and is walled by the extending portion 32 on the inward Xi side of the vehicle body opening from the peripheral edge position of the through hole 15a. It is supported by the inner peripheral surface of the portion 18. Therefore, it is possible to suppress the axial deviation (rattling) of the slide movement of the drive member 30, and it is possible to secure the stable slide movement of the drive member 30.

In the above embodiment, the receiving portion 53 of the case member 50 is in the "first receiving portion" described in the claims, and the receiving portion 32b of the extending portion 32 of the driving member 30 is in the claims. Each corresponds to the described "second receiving part".

By the way, in the above embodiment, the driving member 30 slides in and out of the vehicle body opening X. However, the present invention is not limited to this, and may be applied to a driving member 30 that slides and moves in a direction slightly inclined with respect to the inside / outside direction X of the vehicle body opening. In this inclination direction, the slide axis on which the drive member 30 slides moves from the inward Xi side of the vehicle body opening to the outward Xo side, and when the lid 20 opens, it moves inward Xi of the lid 20. It is the direction that tilts toward the inward movement side. In this modified structure, the lid 20 can be greatly tilted to an angle at which the slide axis of the drive member 30 is tilted with respect to the bottomed base material 10, so that the lid 20 is opened up to a large opening. The opening and closing angle range of the lid 20 can be further expanded.

The present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the spirit of the present invention.
