Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a device for suppressing sliding door opening when refueling an automobile, and in particular, when a fuel is refueled, a fuel lid provided at a refueling port is opened. The present invention relates to a device for restraining the opening of a sliding door when the door is open.

[Prior Art] In a vehicle in which a slide door is provided on the side of a vehicle body and a fuel filler port is provided within a range of movement of the slide door in the opening direction, an occupant accidentally moves the slide door when fuel is supplied. When opened, it may damage the fuel lid that covers the fuel filler port or the fuel gun inserted in the fuel filler port,
The refueling gun may come off the refueling port, causing the fuel to spill.

In order to eliminate such a point, as described in Japanese Utility Model Laid-Open No. 58-99456, a stopper is provided near the slide door,
There has been proposed a door opening restraining device for a slide door that prevents the slide door from opening during refueling by linking this stopper with a lever provided in the vicinity of the fuel filling port or a fuel lid of the fuel filling port using a linkage rod.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technique, the stopper with which the door abuts and the lever or fuel lid on the fuel filler side are directly connected by the rigid linkage rod, and therefore the following problem occurs. There was a problem.

That is, in the prior art, when the sliding door is accidentally opened during refueling, the above-mentioned opening prevention device operates and the sliding door and the stopper come into contact with each other. Even if the operation lever or the fuel lid is tried to be returned to the original state after the refueling is finished in that state, the slide door is still in contact with the stopper and cannot be returned. At this time, if the force is applied with excessive force, the linkage rod, the operation lever on the fuel filler side, or the fuel lid may be damaged.

In addition, even when refueling, it is possible to open the slide door and urgently escape from the vehicle.However, like the conventional device, the stopper and the operation lever or fuel lid on the refueling port side move together. As a result, it is impossible to open the sliding door without damaging the linkage rod or the like, and it is difficult to smoothly escape from the emergency.

The present invention solves the problems of the prior art as described above, and has a simple structure, even when the operation lever on the fuel filler side is returned or the fuel lid is closed when the slide door and the stopper are in contact with each other, It is an object of the present invention to provide a slide door opening prevention device that does not damage these members or linkages.

It is also an object to enable the emergency escape from the inside of the vehicle by opening the slide door without damaging the linkage or the like when the emergency escape is required during refueling.

[Means for Solving the Problems] In the sliding door opening restraining device of the present invention, the fuel filler located within the range of movement of the sliding door mounted on the vehicle body in the opening direction is opened along with the opening operation of the fuel lid. In the sliding door opening restraint device that restrains the sliding door from moving in the opening direction, the storage position is provided on the vehicle body and does not abut the sliding door, and the sliding door abuts on the sliding door. A door opening restraining position for restraining movement in the door opening direction, and a first stopper capable of sequentially rotating in the door opening direction of the slide door to an emergency escape position permitting movement of the slide door in the door opening direction, The first
Is held at a position where the urging spring for urging the stopper of (1) in the storing direction from the door opening restraining position toward the storing position and the first stopper rotated to the door restraining position come into contact with each other A second stopper having a locking portion that is biased in the storage direction by a force that prevents rotation of the first stopper to the emergency escape position; one end side is connected to the fuel lid; A linkage provided with an engagement portion that engages with the first stopper from the storage direction and rotates the first stopper from the storage position to the door opening restraining position when the fuel lid is opened. Is provided as a structural feature.

[Operation] The operation of the sliding door opening restraint device of the present invention having the above-described structure is as follows.

First, when the fuel lid is opened during refueling, the linkage whose one end side is connected to this is operated. Along with this, the engagement portion on the other end side of the linkage engages with the stopper from the storage direction side, and the first stopper is rotated to the door opening restraining position against the spring force of the biasing spring. At this time, the first stopper that has rotated to the restraining position is in a state in which the first stopper is prevented from rotating to the emergency escape position by the locking portion of the second stopper.

In this state, even if an occupant accidentally tries to open the slide door, the slide door comes into contact with the first stopper and cannot move in the opening direction, so that the fuel lid or the fuel gun being refueled may be damaged by the slide door. There is no.

On the other hand, when refueling is completed and the fuel lid is closed while the sliding door which is about to open is blocked by the first stopper, the linkage returns to the original position in conjunction with this. At this time, the first stopper urged in the storage direction is prevented from rotating to the storage position by the slide door, but the engaging portion of the linkage is separated from the first stopper, and the first stopper on the storage direction side is separated. Move to position. Therefore, even if the fuel lid is closed while the first stopper keeps the sliding door from being opened, an unreasonable force is not applied to the linkage and the fuel lid.

In addition, if an emergency escape is required during refueling, if the slide door is moved in the opening direction with a force greater than the force for urging the second stopper, the first stopper will be released. The locking portion of the second stopper is pressed to rotate to the emergency escape position. As a result, the slide door can be opened and the emergency escape from the vehicle can be performed without damaging the linkage or the fuel lid.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the drawings.

It is a fuel lid that opens and closes.

One end side of a linkage cable 6 is connected to the fuel lid 5, and the other end side of the linkage cable 6 extending near the slide door 3 is connected to a stopper device 7 provided on a side portion of the vehicle body 1. Has been done. The other end of the linkage cable 6 is connected to the fuel lid 5 so that the linkage cable 6 is pulled toward the fuel lid 5 when the fuel lid 5 is opened, and is pushed toward the stopper device 7 when the fuel lid 5 is closed. There is.

As shown in FIG. 2, in the stopper bracket 8 of the stopper device 7, the other end of the linkage cable 6 is fixed, and the cable end bracket 9 is the linkage of the present invention.
And a stopper 10, which is the first stopper of the present invention, which prevents the sliding door 3 from moving toward the filler opening in the opening direction, are independently rotatably provided on the shaft 11. Axis 11
A biasing spring 12 for biasing the stopper 10 in the A direction in the drawing, which is the storing direction, is externally inserted in the stopper. The biasing spring 12 causes the stopper 10 to move the stopper 10 to the door stopper portion 10b at one end thereof. Is abutted against the abutting portion 8a of the stopper bracket 8 and the engaged portion 10a on the other end side is abutted against the engaging portion 9a of the cable end bracket 9 and is held at the storage position (see FIG. 3).

In addition, an emergency escape spring 13 which constitutes a second stopper of the present invention is externally inserted into the shaft 11, and one end portion 14a of the stopper 10 located on the engaged portion 10a side and a stopper.
An emergency escape spring stopper (14) having the other end portion (14b) located on the door stopper portion (10b) side of 10 is rotatably provided. The emergency escape spring 13 includes a locking portion 13a locked to one end portion 14a of the emergency escape spring stopper 14,
It has a fastening portion 13b hooked on the stopper bracket 8. The emergency escape spring 13 biases the emergency escape spring stopper 14 in the direction A in the figure by a biasing force much larger than the biasing force of the biasing spring 12, and the other end 14b of the stopper bracket 8 is pressed. Abutment 8a
The engaging portion 13a is held at a predetermined position by the one end portion 14a of the emergency escape spring stopper 14.

When the linkage cable 6 is pulled to the right in the figure by the opening operation of the fuel lid 5, the cable end bracket 9 and the stopper 10 rotate in the direction B in the figure, Stopper at the engaging part 9a
The stopper 10 held in the storage position while pressing the engaged portion 10a of 10 against the urging force of the urging spring 12
Is rotated in the same direction B as the opening direction of the slide door. Further, when the linkage cable 6 is pushed out to the left in the figure by the closing operation of the fuel lid 5, the cable end bracket 9 is in the direction A in the figure, that is, the engaging portion 9a thereof is the engaged portion 10a of the stopper 10. It is designed to rotate in the direction of separating from. Further, as the cable end bracket 9 is rotated, the stopper 10 is rotated in the direction A by the urging force of the urging spring 12, so that the stopper 10 is held at the storage position when the engaging portion 9a is not operated. Has become. When the stopper 10 is rotated in the B direction, the engaged portion 10a abuts on the engaging portion 13a of the emergency escape spring 13, and the door stopper portion 10b projects from the stopper bracket 8 to prevent the door from opening. The position is regulated.

The operation of this embodiment having the above configuration is as follows.

First, when the fuel lid 5 is closed during normal traveling, as shown in FIG. 3, the linkage cable 6 is pushed out to the stopper device 7 side, and the engaging portion 9a of the cable end bracket 9 is engaged with the stopper 10. Since it is separated from the portion 10a, the stopper 10 is held in the storage position.

Next, at the time of refueling, the linkage cable 6 connected to the fuel lid 5 is pulled toward the fuel lid 5 by performing the opening operation of the fuel lid 5, so that the engaging portion 9a of the cable end bracket 9 is engaged with the engaged portion of the stopper 10. Press 10a against the biasing force of the biasing spring 12
Rotate 10 in the B direction toward the door open position. Then, as shown in FIG. 4, the stopper 10 is restricted in position by the locking end portion 13a of the emergency escape spring 13 to the door opening restraining position.

Even if an occupant mistakenly tries to open the sliding door 3 in such a door opening restraining state, the sliding door 3 should come into contact with the door stopper portion 10b of the stopper 10 protruding to the door opening restraining position to open the door. I can't. Therefore, the sliding door 3
There is no problem of damaging the fuel lid 5 or the refueling gun during refueling by opening the door.

On the other hand, when the sliding door 3 which is about to open the door is stopped in contact with the door stopper portion 10b and the refueling is finished and the fuel lid 5 is closed, as shown in FIG. 5, the linkage cable 6 interlocking with the fuel lid 5 is connected. Is pushed to the stopper device 7 side, and the engaging portion of the cable end bracket 9
9a separates from the engaged portion 10a of the stopper 10. In this way, in this embodiment in which the stopper 10 and the linkage cable 6 can be separated, unlike the conventional technique in which the operating lever or the fuel lid and the linkage are directly connected to the stopper, the stopper 10 contacts the slide door 3. Even if it is left as it is, no unreasonable force is applied to the linkage cable 6 or the fuel lid 5 connected thereto.

Further, when the sliding door 3 is opened for an emergency escape during refueling, the sliding door 3 is moved in the opening direction by a large force exceeding the urging force of the emergency escape spring 13 so that the door stopper portion is opened. The sliding door 3 collides with the sliding door 10b to push the door stopper portion 10b, and the engaged portion 1
Since 0a pushes the hooking portion 13a, the stopper 10 further rotates in the B direction against the urging force of the emergency escape spring 13. As a result, as shown in FIG. 6, the stopper 10 rotates to the emergency escape position that allows the slide door 3 to move in the opening direction, so that the slide door 3 can be opened to perform an emergency escape. At this time, no excessive force is applied to the linkage cable 6 and the fuel lid 5 connected to the linkage cable 6, and there is no fear of damage.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, the linkage is not limited to the cable but may be a rod. Further, the connecting structure of the fuel lid and the linkage, the engagement / separation structure of the linkage and the first stopper, and the shape of each member can be freely selected.

On the other hand, as a modification of the above embodiment, the emergency escape spring stopper 14 may be integrated with the stopper bracket 8.

[Effects of the Invention] As described above, in the present invention, an engaging portion is provided on the other end side of the linkage whose one end side is connected to the fuel lid, and this engaging portion can be engaged with and separated from the first stopper. The first stopper is urged in the engagement direction with the linkage by the urging spring, while the second stopper opens the stopper that prevents the sliding door from opening during normal times. It is configured to prevent the door from rotating to the emergency escape position.

Therefore, with a simple structure, even if the fuel lid is closed when the sliding door is in a state in which the opening of the sliding door is suppressed, the member will not be damaged and, in the case of an emergency escape, the member will not be damaged. It is possible to provide a highly reliable sliding door opening prevention device that can open a door.
