BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator safety device for a battery vehicle.

[0002]

2. Description of the Related Art As shown in FIG. 5, an accelerator pedal 5 in a battery vehicle is attached to a rotating arm 7 and a rod 52 disposed below a vehicle floor 6 so that the accelerator pedal 5 can be stepped on. That is, the accelerator pedal 5 has a lower end portion 5
5 is attached to a rotating pin 51 that is provided so as to project on the vehicle floor 6. Further, the accelerator pedal 5 is attached via a mounting tool 521 mounted in the vicinity of the lower end surface 53 of the accelerator pedal.
A rod 52 is attached. Also, the rod 52
The lower end portion 522 thereof is attached so as to be capable of interlocking with each other via a connecting tool 71 fixed to the tip of the rotating arm 7. The other end of the rotating arm 7 is rotatably attached to a sensor shaft 81 projecting from the lower side surface of the accelerator unit 8. The rotating arm 7 includes
The lower ends 92 of the two springs 9, 9 serving as elastic members are attached at substantially the center thereof. Further, the upper end 93 of the spring 9 is a spring hanger 9
It is attached to 1. As a result, the accelerator pedal 5 is normally urged in the opening direction. Further, on the vehicle floor 6, a stopper 61 is provided upright on the lower end portion of the accelerator pedal 5.

Then, as shown in FIG. 5, the accelerator pedal 5 is depressed with a foot. As a result, the rod 52
The rotating arm 7 moves downward in the D direction against the tensile force of the two springs 9. At this time, the sensor shaft 81
Rotates with the rotating arm 7. Further, the spring 9 extends. When the accelerator pedal 5 is further depressed, the lower end surface 53 of the tip comes into contact with the stopper 61. Then, as shown in FIG. 6, in the accelerator circuit T, when the sensor shaft 81 is rotated, a sensor shaft switch (not shown) provided in the accelerator unit 8 comes into contact with the switch contact 80 and the switch is turned on.
Becomes In addition, the speed adjustment terminal 8 provided on the sensor shaft 81
4 moves on the resistor 83 according to the depression amount of the accelerator pedal 5. As a result, the speed of the battery vehicle is adjusted.

[0004]

However, the above-mentioned conventional technique has the following problems. That is, when both of the springs 9 are broken due to strong impact, deterioration, etc., the rotating arm 7 may not return upward only by removing the foot from the accelerator pedal 5. for that reason,
It becomes difficult to move the battery vehicle.

When only one of the springs 9 is broken, the operating state of the accelerator pedal is slightly changed, but the driver rarely notices it. Therefore, the operation is continued until both of the springs 9 are broken, and it becomes difficult to move the battery vehicle as in the above. The present invention has been made in view of the above conventional problems, and provides an accelerator safety device that can maintain safety by continuing to run at a low speed or stopping a vehicle even when an elastic member is broken. Is what you are trying to do.

[0006]

According to the present invention, there is provided an accelerator pedal provided in a battery vehicle, a rotating arm having a sensor shaft and driven by the accelerator pedal, and a rotating stopper arranged below the accelerator pedal. A first elastic member and a second elastic member for constantly urging the accelerator pedal in the opening direction are provided between before and after the rotation fulcrum of the rotation stopper and the rotation arm. Also, the rotation stopper is an accelerator safety device characterized in that an accelerator braking piece is provided at a front end and a rear end thereof. What is most noticeable in the present invention is that a first elastic member and a second elastic member are provided between the front and rear of the rotation fulcrum and the rotation arm, and the front end and the rear end of the rotation stopper. That is, the accelerator braking piece is provided.

As the first elastic member and the second elastic member, for example, coil springs are used. And both are interposed so as to constantly urge the accelerator pedal in the opening direction between the rotary arm and the rotary arm. The rotation stopper has a rotation fulcrum at a central lower portion, and has, for example, hooks at the front and rear thereof for attaching the first elastic member and the second elastic member. Further, the rotation stopper has accelerator braking pieces at its front end and rear end for restricting the depression amount of the accelerator pedal when any of the elastic members is broken. Then, as shown in the second embodiment, it is preferable that the rotation stopper has a larger weight on either the front end or the rear end. Accordingly, even when both the first elastic member and the second elastic member are broken, the rotation stopper can be rotated.

[0008]

In the present invention, since the first elastic member and the second elastic member are provided between the rotation stopper and the rotation arm, the accelerator pedal is always attached in the opening direction. It is energized. However, the first elastic member,
When one of the second elastic members breaks for some reason, the other elastic member pulls one end of the rotation stopper toward the rotation arm. Therefore, the rotation stopper rotates about 90 degrees with the rotation fulcrum as the fulcrum.

As a result, either the front end or the rear end of the accelerator braking piece provided on the rotation stopper is brought into a state of being close to or in contact with the lower surface of the accelerator pedal. Therefore, the accelerator braking piece limits the depression operation of the accelerator pedal, that is, the downward movement (FIGS. 2 and 3). Then, when the accelerator pedal and the accelerator braking piece of the rotation stopper are in the close state, the accelerator pedal can be stepped slightly downward. As a result, the battery vehicle can be safely moved to a repair place or the like by traveling at a low speed.

Further, when the accelerator pedal and the accelerator braking piece are in contact with each other, the accelerator pedal can hardly be depressed. Therefore, the battery vehicle can continue traveling or stop at a speed slower than the slow speed traveling, and safety can be ensured. Therefore, according to the present invention, it is possible to provide an accelerator safety device that can maintain safety by continuing the slow speed running or stopping the vehicle even when the elastic member is broken.

[0011]

EXAMPLE 1 An accelerator safety device according to the present invention will be described with reference to FIGS. That is, as shown in FIG. 1, the accelerator safety device of this embodiment is provided in a battery vehicle, and includes an accelerator pedal 5, a rotating arm 7 having a sensor shaft 81 and driven by the accelerator pedal 5, and It is composed of a rotation stopper 1 arranged below the accelerator pedal 5. Further, a first elastic member 21 and a second elastic member 22 for constantly urging the accelerator pedal 5 in the opening direction are provided between the front and rear of the rotation fulcrum 10 of the rotation stopper 1 and the rotation arm 7. Is installed.

It should be noted that the rotation stopper 1 has an accelerator braking piece 11 in the form of a tapered contact surface at the front end and an accelerator braking piece 12 in the form of a vertical contact surface at the rear end. It is that. In addition, the rotation stopper 1
As shown in FIG. 1, the rotary fulcrum 10 arranged at the lower center of the center, the accelerator braking piece 11, the accelerator braking piece 12 and the hooks 15 and 16 arranged at two lower positions.
And

Further, the rotation stopper 1 is provided on the substantially same horizontal plane as the vehicle floor 6 and the accelerator pedal 5 is provided.
Install below. The first elastic member 21 and the first elastic member 21 are provided between the hooks 15 and 16 arranged at two lower positions of the rotation stopper 1 and the locking holes 70 and 70 arranged in the rotation arm 7. 2 Attach the elastic member 22. Others are the same as those in the conventional example (FIGS. 5 and 6).

Next, the function and effect will be described. In this example, since the first elastic member 21 and the second elastic member 22 are provided between the rotation stopper 1 and the rotation arm 7, the accelerator pedal 5 is always attached in the opening direction. It is energized. However, as shown in FIG. 2, when the second elastic member 22 is broken for some reason, the first elastic member 21 causes one end of the rotation stopper 1 to move in the direction of the rotation arm 7 as indicated by an arrow A. Will be pulled to. Therefore, the rear end of the rotation stopper 1 rotates about 90 degrees with the rotation fulcrum 10 as a fulcrum. As a result, the rear end accelerator braking piece 12 provided on the rotation stopper 1 rotates in the B direction and comes into a state of being close to the accelerator pedal 5 with a clearance t maintained. Therefore, the vertical braking surface-shaped accelerator braking piece 12 restricts the depression operation of the accelerator pedal 5, that is, the downward movement, as shown in FIG.

On the other hand, as shown in FIG. 3, when the first elastic member 21 is broken, the second elastic member 2 is used.
2 pulls one end of the rotation stopper 1 as shown by an arrow A. Therefore, the accelerator braking piece 11 is C
It rotates in the direction and comes into a state of being close to the accelerator pedal 5 while maintaining the clearance t. Therefore, as shown in FIG. 3, the tapered braking surface-shaped accelerator braking piece 11 is
The movement of the accelerator pedal 5 will be restricted. Since the accelerator pedal 5 and either of the accelerator braking pieces 11 and 12 of the rotation stopper 1 are in the proximity state with the clearance t maintained as described above, the accelerator pedal can be stepped slightly downward. it can. As a result, the battery vehicle can be moved to a repair place or the like at a slow speed. That is, the battery pedal can be driven at a very low speed by depressing the accelerator pedal by the clearance t existing between the rotation stopper 1 and the accelerator pedal 5.

Embodiment 2 An accelerator safety device according to this embodiment is as shown in FIG.
The accelerator braking piece 12 at the rear end of the rotation stopper 1 in the first embodiment is replaced by a rectangular parallelepiped accelerator braking piece 13. That is, the accelerator braking piece 13 has a tapered abutment surface-shaped accelerator braking piece 11 arranged at the front end.
It has a rectangular shape with a large weight. Therefore, when both the first elastic member 21 and the second elastic member 22 are broken for some reason, one of the heavier accelerator braking pieces 13 moves downward G as shown in FIG. . Therefore, the tapered braking surface-shaped accelerator braking piece 11 moves upward H. As a result, the taper contact surface-shaped accelerator braking piece 11 restricts the depression of the accelerator pedal 5. Further, instead of the rectangular-shaped accelerator braking piece 13, the weight of the tapered braking surface-shaped accelerator braking piece 11 can be increased. Further, an eccentric weight may be attached to the front end or the rear end of the rotation stopper 1 on the back surface side. Therefore, also in this example, it is possible to obtain the same effect as that of the first embodiment.
