Description

  The present invention relates to a device for preventing erroneous depression of an accelerator pedal and a brake pedal of an automobile.

  In order to prevent the mistaken depression of the conventional accelerator pedal and the brake pedal, there is a device in which the operation of the brake pedal and the accelerator pedal is made in different directions so as not to make a mistake (see, for example, Patent Document 1).

  Utility Model Registration No. 3015074

  In the conventional apparatus described above, in the case of the accelerator operation, acceleration is performed by moving the accelerator lever to the right lateral direction and the accelerator lever is moved, but when decelerating, the lateral angle of the foot needs to be returned to the initial state. Yes, the accelerator lever must automatically return to idling accordingly.

  Since the brake operation must be stepped forward, it is dangerous if the brake lever is not depressed when the accelerator lever is automatically restored. There may be a device that overcomes this point and can operate the brakes even if the foot is depressed without returning the foot angle, that is, a device that mechanically returns the accelerator lever mechanically. The lateral angle must be restored to the initial state before the accelerator operation.

  The present invention is intended to solve such a conventional problem, and is intended to be operated more quickly.

  Inside the main accelerator pedal 1, a follower pedal 2 having stoppers at the front and rear is provided coaxially to form an interlocking arm a 3 and an arm fixing plate 4. The pedal receiver 19 is rotatably provided and a torsion spring 24 is provided. An accelerator pedal provided with a link mechanism for connecting and interlocking the upper part of the arm a3 attached and the upper part of the arm b7 integrated with the arm c8 provided with the pedal retainer 9 by the joint 5 and the rod 6; Install a brake pedal misstep prevention device so that the accelerator and brake operations are in different directions.

  Since the operation of the accelerator and the brake are completely opposite, not only the mistake of stepping on the accelerator pedal and the brake pedal can be prevented, but also the operation can be performed quickly, so accident prevention can be expected.

  FIG. 1 shows the overall configuration of a stepping error prevention device according to the present invention. Hereinafter, an embodiment will be described with reference to FIGS.

  In FIG. 1, a follower pedal 2 is formed inside the main accelerator pedal 1, and an upper part of an arm a <b> 3 that moves in conjunction with the other part of an arm c <b> 8 provided with a pedal presser 9. The upper part is connected by a joint 5 and a rod 6 to constitute a link mechanism, and a base part is also illustrated. A pedal receiver 19 which is a base of the pedal device and a base 16 installed on the floor surface are connected to an angle 15 by a plate 17, and further, a base 12 which is a base of a link mechanism is a shim plate a13 and a shim plate b14, an angle This shim plate adjusts the parallelism of the front link mechanism and the rear pedal device. A fulcrum of the front link mechanism is fixed to the gantry 12 by a support 11.

  Next, regarding the installation of the device, the front link mechanism is disposed between the accelerator pedal and the brake pedal, and the rear pedal device is disposed behind the brake pedal. In this state, the height and level are adjusted simultaneously at three locations of the level bolt 27 of the base 16. In order to prevent this device from moving, the two holes at the front and rear of the stay attachment hole a28 and the stay attachment hole b29 are used, but the stay is attached to the frame of the driver's seat, and the stay attachment hole a28 and the stay attachment hole b29 Since it fits, tighten the bolts and tighten them. Then, the buffer material and the mat are cut out and covered on the base 16 only in the way.

  Although it is the base part to be fixed, the specifications of the driver's seat frame may differ depending on the vehicle type, so depending on the installation method, the rear pedal receiver 19 is attached to the rib on the floor of the driver's seat and the front link mechanism is If the supporting support 11 can be fixed from the frame in front of the driver's seat via the mounting stay, the parts from the plate 17 to the gantry 12 become unnecessary. The figure shows the implemented structure.

  FIG. 2 shows a partially enlarged exploded perspective view related to the main accelerator pedal 1, which is a little larger than FIG. 1. The main accelerator pedal 1 and the follower pedal 2 are assembled to the pedal receiver 19, and except for the follower pedal 2, flange bushes 32 are press-fitted to the left and right respectively. The shaft a30 and the shaft b31 are passed from both outsides of the pedal receiver 19, the left and right sides of the main accelerator pedal 1 are fitted through the arm a3 only on the inner right side, and the nut 26 and the flat washer small 39 are attached to the screw portions of the shaft a30 and the shaft b31. Each of the following pedals 2 is fitted inside the main accelerator pedal 1 while being attached, and both side surfaces are locked with double nuts of nuts 26. At this time, since both side surfaces of the follow-up pedal 2 are clamped by the nut 26 and tightened, the shaft a30 and the shaft b31 move together.

  Next, the arm a3 is free only by passing through the shaft b31. Therefore, the arm fixing plate 4 is attached so as to move integrally with the follower pedal 2. First, the small spring washer 40 and the plain washer are mounted in the lower hole. A spacer 34 is attached through a bolt a 22 fitted with a small 39, and is attached to a mounting hole of the follower pedal 2 with a small flat washer 39 and a nut 26. Then, the upper elongated hole portion is attached to the screw hole of the arm a3 with a bolt b23 into which the spring washer middle 38 and the plain washer middle 37 are fitted. Since the long hole portion is adjusted to an appropriate angle, it is fastened and fixed at two positions at an appropriate angle.

  Further, the adjustment bolt a20 and the adjustment bolt b21 are fastened and fixed to the mounting hole at the rear part of the follow-up pedal 2 with a nut 26 from above and below, respectively. Similarly, the adjustment bolt c33 is attached to the front attachment hole. However, in FIG. 2, since the attachment hole is hidden and cannot be seen, only the adjustment bolt c33 is illustrated. The adjustment bolt a20 is a stopper when the accelerator is fully opened. Then, the adjustment bolt b21 is for adjusting the contact between the main accelerator pedal 1 and the follower pedal 2, and the mounting hole surface is somewhat inclined so that the contact surface is vertical. The front adjustment bolt c33 is a stopper when the accelerator is in an idling state.

  Even with this alone, the main accelerator pedal 1 and the follower pedal 2 transmit the movement of the existing accelerator pedal. Therefore, even if the pedal is depressed, the main accelerator pedal 1 and the follower pedal 2 are automatically restored. The b31 is fitted with a guide rod 35, the tip is put in the spring hooking hole of the arm a3, and the other is hooked on the hooking bolt 25 so that the flat washer 36 and the nut 26 are double attached.

  FIG. 3 is a partially enlarged exploded perspective view related to the arm b7 and the arm c8. The bush a41 is press-fitted into the arm b7 and the arm c8, respectively, and the two knock pins 43 form a fixed angle. It is united. A fulcrum is configured by inserting a shaft c44 into the bush a41 and passing a fulcrum bolt 45 fitted with a small spring washer 40 and a large flat washer 36, and tightening and fixing to a screw hole of the support 11.

  The pedal retainer 9 is assembled to the screw hole of the arm c8 with a small flat washer 39 and a nut 26 with the mounting bolt 10 as an axis at the tip of the arm c8. This pedal retainer 9 is made of resin, and is adjusted to a rotating state and locked with a nut 26. The arm b7 is a single part with a threaded shaft. The joint 5 into which two bushes b42 are press-fitted is fitted into this shaft, and is assembled with the small flat washer 39 and the nut 26. At this time, the joint 5 is locked by a double nut 26 in a rotating state.

  Next, an operation method and an operation state will be described. In short, if the main accelerator pedal 1 is tilted backward with the sole of the foot, the arm a3 rotates about the fulcrum of the arm b7 via the joint 5 and the rod 6. Then, the pedal presser 9 operates the existing accelerator pedal. Hereinafter, it will be described in detail as an automatic vehicle.

  The main accelerator pedal 1 is arranged so that the kite rides a little before the fulcrum of the main accelerator pedal 1 if the foot is placed in a state where the brake pedal is normally put on, but may be up to the fulcrum. This fulcrum refers to a portion having axes a30 and b31 shown in FIG. In this way, the brake operation is performed by stepping forward from the state where the foot is put on the brake pedal. At that time, since the main accelerator pedal 1 has a slope and is lowered as it goes forward, the heel portion does not come into contact.

  The accelerator can be operated just by releasing the brake pedal, so the car may move according to the situation, but in order to start normally, if you are on the brake pedal, While lifting a little, that is, tilting the ankle angle forward, slide the foot backward. To what extent, slide your toes to the point where at least half of the brake pedal is engaged. At this time, the heel part comes to the last part of the main accelerator pedal 1. At the same time, when the foot is lowered, the heel part pushes down the rear part of the main accelerator pedal 1, and the front jumps up at the fulcrum, so that it comes to stick to the sole of the foot. At this time, the accelerator has already been adjusted to work a little and the vehicle is in a starting state. How much the accelerator works can be finely adjusted with the height of the adjusting bolt b21. Then, to accelerate, accelerate as you tilt the ankle angle backward. If it returns, it will slow down. To make it idle, the toes should be lifted with the toes lightly touching the brake pedal.

  To brake from a running state, the ankle angle is slightly backward at medium speed and the toes are slightly lifted from the brake pedal. It just takes a step forward. Even if it is said that the angle of the ankle is tilted backward from the medium speed when it is from high speed, it is a little away from the brake pedal, but it is not so much, if you do the same action, but if you feel a little larger movement Good. At this time, the main accelerator pedal 1 does not contact the heel, but as the inclination increases, the force to return by the torsion spring 24 increases, and in addition, the force to return the existing accelerator pedal also increases. So automatic recovery is faster. Therefore, there is no problem when the brake operation is performed instantaneously even though it does not contact, even if it makes contact, the accelerator is forcibly returned. Because it is direct, it is faster than the conventional stepping.

  Further, a supplementary explanation will be given to make it easier to understand the above matters. Since the main accelerator pedal 1 has play between the follower pedal 2 and the link mechanism for moving the accelerator is connected to the follower pedal 2, the accelerator works only when the follower pedal 2 is moved. Further, the main accelerator pedal 1 has a notch on the side surface so as not to come into contact with the spacer 34, and moves in pairs because it is coaxial with the adjustment bolt b <b> 21 provided at the rear part of the following pedal 2. When returning, a force acts in the direction in which the follower pedal 2 returns the main accelerator pedal 1 via the adjusting bolt b21. When the following pedal 2 is in an idling state, the head of the adjustment bolt c33 provided at the front portion hits the end surface of the pedal receiver 19 and stops. Thereafter, the main accelerator pedal 1 moves to a predetermined position with momentum and balance. That is, it stops at a position in contact with the end surface that is the front of the follower pedal 2.

  The reason why the above-mentioned play is provided is that the sole of the foot is not enough to sensuously recognize the degree of movement of the accelerator, and if the pedal is put on the sole of the foot, the angle of the ankle This is because the degree of acceleration can be recognized. Easy pedal operation.

  When the accelerator pedal device is operated, there is versatility in that the foot size differs depending on the person because it can be operated appropriately. As for the appropriate operation, a small person should just shift his feet. A large person can operate without shifting because the heel reaches the rear part of the main accelerator pedal 1 just by lifting and lowering the heel at the ankle while depressing and returning the brake pedal forward. Therefore, it is possible to adjust the front and rear positions to some extent. Although this will be described in detail later, as described above, the operation of the accelerator pedal and the brake pedal is not reversed by mistake because the operation is completely reversed while moving the foot back and forth.

  Specifically, a description will be given with reference to FIG. The arm a3 can be moved freely by loosening the bolts a22 and b23, which are fastened and fixed by first fastening the arm fixing plate 4. Then, the fastening bolt 18 that fastens the plate 17 to the angle 15 is loosened, and then the bolt that is fastened through the stay mounting hole a28 of the pedal receiver 19 is loosened. When these four places are loosened, the stay attachment hole a28 for fixing the pedal receiver 19 and the portion through the tightening bolt 18 are elongated holes, so that they can be moved. If the pedal receiver 19 is moved forward, the arm a3 is free so that it tilts backward, and if it moves backward, the arm a3 tilts forward. In order to fix at an appropriate position, the bolt that is tightened through the tightening bolt 18 and the stay mounting hole a28 is tightened. Next, the inclination of the arm a3 remains unchanged unless the length is changed by screwing the rod 6 into the joint 5. If it is shortened, it will tilt forward, and if it is long, it will tilt backward. Therefore, if the bolts a22 and b23 that have been loosened are tightened and tightened, the position adjustment of the front and rear of the pedal device will be completed.

Next, an operation method and an operation state will be described. In brief, when the main accelerator pedal 1 is tilted backward on the sole of the foot, the arm a3 rotates the arm b7 about the fulcrum of the arm b7 and the arm c8 via the joint 5 and the rod 6 . Then, the pedal presser 9 operates the existing accelerator pedal. Hereinafter, it will be described in detail as an automatic vehicle.

If you put your foot on the normal brake pedal, place the main accelerator pedal 1 so that the heel rides from a little behind the fulcrum of the main accelerator pedal 1 for those who are a little smaller than normal. doing. This fulcrum refers to a portion having axes a30 and b31 shown in FIG. In this way, the brake operation is performed by stepping forward from the state where the brake pedal is put on. At that time, the main accelerator pedal 1 is in contact with the sole of the foot bounce forward depending on the position placing the feet, the main accelerator pedal 1 since the foot is moved to the front in accordance with stepping is the forward boundary of fulcrum It is forcibly lowered by the part in contact with the sole of the foot and does not affect the brake operation. Also, if you operate with the kite floating, you will not touch.

The main accelerator pedal 1 is a free pedal that quickly adapts to the movement of the foot, as will be understood from the above description and FIG. When the accelerator operation is performed, the state in which the main accelerator pedal 1 is attached to the sole of the foot is expressed as play, but in actuality, it is only adapted to the movement of the foot. This is because the degree of acceleration can be recognized by the angle of the ankle when the pedal is put on the sole of the foot. Although it is said that the accelerator has already been applied for a while in a state where the sole of the foot is attached to the sole, it is a case where the operation is performed by shifting the foot back and forth, in order to operate quickly. Basically it is better not to work. After the main accelerator pedal 1 is attached to the sole of the foot, the main accelerator pedal 1 moves in a pair with the follower pedal 2, and only during that time, the range of the accelerator is limited. As described above, the combination of the main accelerator pedal 1 and the follower pedal 2 enables the accelerator and the brake operation to be performed quickly.

Specifically, it described referring to FIG. The arm a3 can be moved freely by loosening the bolts a22 and b23, which are fastened and fixed by first fastening the arm fixing plate 4. Then, the fastening bolt 18 that fastens the plate 17 to the angle 15 is loosened, and then the bolt that is fastened through the stay mounting hole a28 of the pedal receiver 19 is loosened. When these four places are loosened, the stay attachment hole a28 that has fixed the pedal receiver 19 and the portion that has been passed through the tightening bolt 18 are elongated holes so that they can be moved. If the pedal receiver 19 is moved forward, the arm a3 is free so that it tilts backward, and if it moves backward, the arm a3 tilts forward. In order to fix at an appropriate position, the bolt that is tightened through the tightening bolt 18 and the stay mounting hole a28 is tightened. Next, the inclination of the arm a3 remains unchanged unless the length is changed by screwing the rod 6 into the joint 5. If it is shortened, it will tilt forward, and if it is longer, it will tilt backward. Therefore, if the bolts a22 and b23 that have been loosened are tightened and tightened, the position adjustment of the front and rear of the pedal device will be completed.
