Description
[Technical field]
[0001] The present invention relates to a device for preventing mistaken application of an accelerator pedal instead of a brake pedal in an automobile. [Background technology]
[0002] Conventionally, there is a device for preventing the driver from mistaking the accelerator pedal for the brake pedal by operating the brake pedal in a different direction to prevent the driver from mistaking the accelerator pedal for the accelerator pedal (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2012-164067 A Summary of the Invention [Problem to be solved by the invention]
[0004] In the known technology of Patent Document 1, an accelerator mechanism is provided by connecting an auxiliary pedal to an existing brake pedal, and the auxiliary pedal is provided with an accelerator pad that is acted on laterally to the right by the toes. The accelerator is operated by placing the foot on the auxiliary pedal and opening the toe to the right, with the heel at the center, but with a conventional accelerator pedal, the force is applied vertically, so strong pressure can be applied, but it is not possible to apply strong pressure horizontally. In addition, the fatigue caused by maintaining the vehicle moving and repeatedly operating the pedal is greater in the horizontal direction than in the vertical direction, which creates a problem.
[0005] To overcome this, an appropriate amount of operating force is required. The coil spring that is biased to return the accelerator to its original inoperative position also has a significant effect on this, so reducing this effect is also a challenge. [Means for solving the problem]
[0006] As a means to solve this problem, in the conventional step-on accelerator pedal, the toe presses on the center of the pedal's vertical width, but to make the operation force lighter, an accelerator arm 9 is attached to the existing accelerator pedal, and a roller A 14 is provided at the tip of the accelerator arm 9 so as to press the rear of the rear end of the accelerator pedal, and when the roller A 14 is pressed, the distance from the pressing position to the fulcrum becomes longer, so the moment acting on the accelerator becomes larger, and it becomes possible to operate it with a lighter force. Therefore, the operation width of the toe becomes larger, but it is acceptable.
[0007] In order to enable the light operation described above, when roller 1 on the arm is moved to the right on the right side of the toe, centered on the heel that is in contact with the floor, roller 19 B on the tip of the other arm that moves integrally around the axis is positioned perpendicular to the upper side of roller 14 A, thereby pressing down on roller 14 A.
[0008] To add, when moving roller 1 to the right on the right side of the toe, the side where the operating force from the toe is transmitted as a moment to the arm with roller 1 attached and the moment on the other arm to which this force is transmitted are balanced, so by changing the length ratio, the width at which roller A is pressed and the operating force will change. 1 Roller turning radius By setting the above ratio appropriately, an appropriate operating force can be obtained. Effect of the Invention
[0009] Toes On the right side, move the roller to the right with light acceleration. This reduces fatigue. Not only that, braking while releasing the roller is much faster than the conventional method of releasing the accelerator pedal and then depressing the brake pedal, and since the accelerator and brake pedals are operated in different directions, This helps prevent accidents by preventing drivers from mistaking the accelerator pedal for the brake pedal. [Brief description of the drawings]
[0010] [Figure 1] A perspective view of the present invention. [Diagram 2] FIG. 1 is a partially exploded perspective view of the present invention; [Diagram 3] FIG. 1 is a partially exploded perspective view of the present invention; [Figure 4]Diagram of the relationship between the toes and the arm during operation DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] FIG. 1 shows the overall configuration of the device for preventing misstepping of the present invention, and FIG. 2 shows an enlarged exploded perspective view of the part where the part is attached to the existing accelerator pedal. The device will be described with reference to FIG. 1 and FIG. 2. The existing accelerator pedal and brake pedal are used as they are, and hereinafter will be simply referred to as the accelerator pedal and brake pedal. The accelerator arm 9 is attached to the accelerator pedal, and the accelerator arm 9 is supported at two points, the upper and lower parts of the accelerator pedal part. The upper part is the same part, and the two holes of the side plate 10 are arranged on the left and right with the holes on the upper side and the curved side facing inward, and between them, the side hole of the mounting plate 12, which is slightly narrower than the width of the accelerator pedal, is arranged on the upper side, and a bolt and a washer are passed through the hole and attached with a nut, but the bolt head is first placed downward in the center hole of the mounting plate 12 so that the mounting plate 12 is sandwiched between the nuts. The right side is different from the left side in that the spacer 11 is fitted and the upper hole of the accelerator arm 9 is aligned and attached. Next, the lower part is attached in the same way, but the two 13 horizontal clamps that hold both sides are flat and only clamp both sides, so that when adjusting the height up and down, the clamping can be done even if the height changes. The 12 mounting plate placed between these 13 horizontal clamps is the same part as the upper part, but in the opposite direction. The bolts are attached in advance in the same way as the upper part, and the right side is attached in the same way as the upper part, aligning the lower holes of the 9 accelerator arm.
[0012] The 14 roller A at the tip of the 9 accelerator arm is fixed with a bolt and nut in a rotating state. The 19 roller B is placed perpendicular to the top of the 14 roller A, and the 20 stay is installed using the accessory hole provided on the vehicle, and the 2 roller arm A, 4 roller arm B, 7 axle C, and other parts are assembled to the 8 mounting plate already provided on the 16 base. When the 16 base is installed on the 20 stay, the 19 roller B is placed perpendicular to the top of the 14 roller A. To ensure that the 19 roller B holds the 14 roller A properly, the front-to-back position and height of the 14 roller A must be adjusted to match the 19 roller B. The adjustment method is to align the front-to-rear position of the upper part that supports the accelerator arm 9 and place the central bolt of the mounting plate 12 against the accelerator pedal to set the height and front-to-rear position. Next, to adjust the height of the accelerator arm 9, the height at which the head of the central bolt of the lower mounting plate 12 touches the accelerator pedal is the desired height. This height changes the inclination of the accelerator arm 9, and determines the height of the roller A 14 at the tip. This type of adjustment means is a feature of this product.
[0013] Figure 3 shows a partially enlarged exploded perspective view of the roller arm part operated by the toe, and will be explained with reference to Figures 1 and 3. Roller 1 is arranged to be located at a fixed distance to the right of the rear end of the brake pedal. Roller arm 4 B is aligned at a fixed angle to the upper lower part of roller arm 2 A, and is integrated with two roll pins 17 to provide shaft holes, into which bushes 18 are inserted to ensure smooth rotation, and shaft parts 3 A and 5 B are provided on the other sides. Roller 1 is fixed to shaft part 3 A in a rotating state with a washer and double nut, and roller 19 B is fixed to shaft part 5 B in a rotating state with a washer and double nut.
[0014] The 2-roller arm A and 4-roller arm B are fixed in a rotating state to the 7-axis C of the 6-arm receiver with a washer and double nut. This 6-arm receiver is attached to the 8-mounting plate with a bolt, washer, and nut in advance, and 4-roller arm B is fixed so that it moves parallel to the line connecting the idling position and full throttle of the trajectory drawn by the rear end of the accelerator pedal. To prevent this inclination from changing, the 15-stopper is fixed in a position where it contacts the left side of the 6-arm receiver. This 15-stopper also serves as a stopper to stop 2-roller arm A from moving more than necessary to the left. The front-rear and height positions of the 14-roller A are adjusted in a temporary fixing state using the adjustment method described above so that it fits the 19-roller B fixed in this way, and finally each part is tightened and fixed.
[0015] Figure 4 shows the relationship between the opening of the toes and the 2 roller arm A when the 1 roller is operated with the toes opened to the right side around the heel, and will be described with reference to Figures 1 and 4. When the 1 roller, which is disposed between the brake pedal and accelerator pedal of a vehicle, is moved to the right on the right side of the toes, the toes and the 1 roller are in contact so the movement distance is the same, but if the distance from the point where the heel touches the floor to the contact point between the 1 roller and the toes is taken as the rotation radius of the toes, and the distance from the 7th axis C of the 6th arm receiver to the contact point between the 1 roller and the toes is taken as the rotation radius of the 1 roller, the rotation radius of the 1 roller is relatively shorter than the rotation radius of the toes. If we compare this with the angle at which the toes open, α, and the angle at which one roller moves, β, then β is relatively larger than α. In other words, if the radius of rotation of one roller becomes shorter than the radius of rotation of the toes, the angle at which one roller moves becomes larger than the angle at which the toes open. By changing the ratio of the radius of rotation of this 1 roller to the radius of rotation of 19 rollers B, the toe opening can be made smaller or larger. This is a structural feature.
[0016] Depending on how you look at it, the above features can be both disadvantages and advantages. In order to make the accelerator pedal easier to operate, pressing the 14 roller A, which is located behind the rear end of the accelerator pedal, increases the pressing width, but the toe opening can be made to be not so large. However, it can be considered a disadvantage because it makes the operation heavier. If you want to make it lighter even if it means increasing the toe opening, you can shorten the length from the 7th axis C to the 19th roller B, which is the turning radius of the 19th roller B, and make it compact, so it can be considered an advantage. This also has the feature of meeting the operability required by users by utilizing the above disadvantages and advantages. This can be obtained by making the ratio of the turning radius of the 19th roller B to the turning radius of the 1st roller appropriate. The word appropriate here refers to matching the operating feel required by each person. For example, if you never use the accelerator fully open and want it to be even lighter, you can make the toe operating width larger and not use the range close to full open, and the operating width will not be so large.
[0017] The force generated by multiplying the toe's operating force by the radius of rotation of the first roller is transmitted as a moment, so the radius of rotation of the first roller is made as large as possible. For this reason, the second roller arm A is tilted toward the brake pedal, making it slanted, to make the radius of rotation of the first roller as long as possible. In this way, by securing the radius of rotation of the first roller, if you press somewhere behind the rear end of the accelerator pedal, you can see how much larger and lighter the operating range will be compared to when operating at the center of the vertical width of a foot-operated accelerator pedal, so The position you have decided on is the 14 roller A, and the 19 roller B is placed to press it down. The length of the turning radius of roller 19 B relative to the turning radius of roller 1 is to be determined. In this case, if the turning radius of roller 19 B is made shorter, the operation will become lighter and the operating range will increase. If the turning radius of roller 19 B is made longer, the operation will become heavier and the operating range will decrease. Specifically, how to determine the above ratio is as follows: The length of the radius of rotation of roller B (19) relative to the radius of rotation of roller (1) is determined so that the desired operation when pressing roller A (14) directly is the operation of the toe. It may seem confusing, but it is just the rotation radius of 19 roller B that is indirectly involved in the rotation radius of 1 roller.
[0018] Next, the operating method of the present invention and the features given to the operation will be explained with reference to Fig. 1 for an automatic vehicle. First, regarding the position of the feet, place the toes on the brake pedal and the heels on the floor. When starting the engine, depress the brake pedal with the toes and make sure to put the shift lever in P range before starting. With the brake depressed in this state, move the shift lever from P range to D range or R range, and gradually release the toes from the brake pedal, and the car will gradually start to move due to the creep phenomenon. In this way, the accelerator is operated by returning the toe from the brake pedal, but the toe is returned a little further than the brake pedal's fully returned position, and at the same time, the heel is placed on the floor, and while lifting the toe slightly off the brake pedal, the heel is used as the center and the right side of the toe is operated to the right, and 19 roller B, which is located at the tip of 4 roller arm B that moves together with 2 roller arm A, presses 14 roller A, so that the accelerator is pressed down and the vehicle accelerates. The accelerator itself has a built-in compression spring that urges it in the return direction, so returning the toe opening will decelerate the vehicle.
[0019] As with the accelerator operation described above, it is normal to lift your toe slightly off the brake pedal and operate the first roller to the right, but if you lift it farther, the distance from the seventh axis C to the contact point with the first roller and the toe becomes longer, which increases the moment and makes the brake lighter. In addition, roller 1 moves in an arc around axis C, and until it reaches the apex of the arc, the right side of the toe and the part in contact with roller 1 are induced to rise up, but as it passes the apex, both the direction in which the toes open and the direction of the arc become diagonally downward, making it easier to transmit force.
[0020] When braking, you return your toes to their original position and press the brake pedal with your toes, but when you return your toes to their original position, you can press the brake pedal quickly. Specifically, if you return your toes to a diagonal downward position rather than returning them to a parallel position and then pressing the brake pedal, your toes will land more easily on the brake pedal, making the operation faster. At this time, the first roller is tilted to the left and the lower side is released, so the toe can move diagonally downward to the left without touching the first roller. With this series of actions, you can quickly press the brake pedal as soon as your toe lands on the brake pedal. This is much faster than the conventional accelerator and brake pedal, where you release the accelerator while pressing the brake pedal.
[0021] When returning the toes diagonally to the lower left, the 2 roller arm A and 4 roller arm B, which are returned by the accelerator pedal, do not need coil springs to bias them in the return direction. The reason why they are not needed will be explained with reference to Figure 1. Looking at Figure 1, it is an oblique view, so it is turned sideways and tilted forward. Therefore, the surface of the 6-arm support looks like it is facing upwards, but in fact it is tilted forward so that it is at a right angle to the accelerator pedal. Like the 6-arm support, 2-roller arm A and 4-roller arm B are also tilted forward. This affects the left-right balance, so if no force is applied, it will move to the heavier side. Comparing 2-roller arm A and 4-roller arm B, 2-roller arm A is heavier, so it tilts to the left and hits the stopper 15, where it stops. Because of this, it is returned to the left side without any resistance, eliminating the need for a coil spring to bias it in the return direction. This contributes to making the accelerator operation lighter. In addition to the above, when roller 1 is moved to the right, roller 14 A attached to the end of accelerator arm 9 attached to the accelerator pedal is returned by the accelerator pedal to return roller 19 B attached to the end of roller arm 4 B, but since roller 14 A and roller 19 B both rotate, contact resistance is kept to a minimum.
