Description

  The present invention relates to a pedal device.

  As pedal devices mounted on vehicles such as automobiles, hybrid vehicles, and electric vehicles, there are known suspension pedal devices and organ-type pedal devices that have different arrangement relationships of pedal tread spindles with respect to the vehicle body. The suspension pedal device is called in this way because the pedal tread spindle is positioned above the pedal tread and the pedal tread appears to be suspended when viewed from the driver. The organ-type pedal device is called in this way because the pedal tread surface support shaft is located below the pedal tread surface and is similar to a pedal used for an organ of a musical instrument.

General passenger cars are equipped with a hydraulic brake equipped with a vacuum booster to amplify the treading force of the brake pedal tread to ensure sufficient braking power even when the amount of pedal treading by the driver is small doing. In this case, since it is difficult to dispose the configuration of the vacuum booster or the like below the passenger compartment floor surface, it is common to employ a suspended pedal device as a brake pedal. On the other hand, large lorries and the like are equipped with pneumatic brakes, and in this case, the configuration of a vacuum booster or the like is not necessary, so an example of adopting an organ-type pedal device as a brake pedal can be seen. These differences in adoption rates are largely due to differences in vehicle structure.
In addition, the accelerator pedal can be seen to employ an organ-type pedal device in all vehicles.

As a method of depressing the pedal by the driver, the first method in which the foot is completely lifted off from the passenger compartment floor and the ankle is pivoted with the heel as a fulcrum while the foot heel is in contact with the passenger compartment floor. There is a second way to step in. Since the first method places a burden on the driver's foot, the driver often adopts the second method particularly during long driving.
When the driver adopts the second method, in the organ-type pedal device, as shown in FIG. 10, the rotation fulcrum P of the driver's foot 25 and the rotation fulcrum Q of the pedal device 26 are close to each other, The driver's foot 25 and the pedal tread surface of the pedal device 26 draw substantially the same turning trajectory. For this reason, it is possible to continue the stepping operation while the driver's foot 25 is stepping on substantially the same part of the pedal tread surface, and the operability felt by the driver is less uncomfortable and less fatigued. However, since the pedals and the mechanisms related to the pedal operation are concentrated on the floor of the driver's seat, there are problems that the restrictions on the layout of the vehicle are large and the water resistance and dirt resistance are low.

  On the other hand, in the suspension type pedal device, since each mechanism related to the pedal and the pedal operation can be arranged on the engine room side, there are almost no restrictions on the layout of the vehicle, and the water resistance and the dirt resistance can be kept high. However, when the driver adopts the second method described above, the suspension type pedal device has a pivot fulcrum P of the driver's foot 25 and a pivot fulcrum R of the pedal device 27 as shown in FIG. The driver's foot 25 and the pedal tread surface of the pedal device 27 are different from each other and draw different rotation trajectories. For this reason, the stepping operation is continued so that the driver's foot 25 slides on the pedal tread surface, and the driver feels uncomfortable with the operability. When the pedal device 27 is a brake pedal, the tread surface is almost made of rubber in order to prevent slipping, so that the driver's feet are less likely to slip with respect to the tread surface, and the feeling of strangeness becomes remarkable. When the pedal device 27 is operated with the heel away from the floor to prevent this uncomfortable feeling, the feeling of fatigue increases.

In order to solve the above-mentioned problems, by changing the angle of the pedal tread when the pedal is depressed, it is possible to prevent the driver's ankle from flexing unnaturally and increase the burden, and to efficiently apply the treading force to the tread. A technique for transmitting is proposed (see, for example, “Patent Document 1”).
Further, there has been proposed a technique for changing the angle of the pedal tread surface and generating a desired pedal reaction force when the driver adopts the second method (see, for example, “Patent Document 2”).

JP 2009-90838 A JP 2010-218389 A

In any of the above-described techniques, the pivot point of the driver's foot and the pivot point of the pedal device tread are separated from each other, so that the driver's foot does not slide on the tread as the pedal tread is depressed. The user feels uncomfortable or tired and the operability deteriorates.
An object of the present invention is to solve the above-mentioned problems and to provide a pedal device capable of improving operability without feeling uncomfortable or fatigued during operation and a vehicle including the pedal device.

It is possible to move in a direction away from the moving position.

  According to a fifth aspect of the present invention, in the pedal device according to the fourth aspect of the present invention, the second pedal tread surface is rotatably attached to the surface side of the first pedal tread surface.

  According to the present invention, the rotation trajectory drawn by the driver's foot and the movement trajectory drawn by the pedal tread can be substantially matched, and the position where the driver's foot contacts the pedal tread is related to the depression amount of the pedal tread. Therefore, it is possible to provide a pedal device that can improve operability without feeling uncomfortable or tired when depressed.

By fitting the protrusions 13 a into the concave grooves 12 a, the pedal tread surface 12 is configured to be movable in the rotational radius direction of the pedal arm 11 on the base member 13. Stoppers 12b and 12c for restricting the movement of the pedal tread 12 on the base member 13 are integrally formed at the upper and lower ends on the back side of the pedal tread 12, respectively.

FIG. 5 is a view of the state in which the pedal tread surface 12 is movably mounted on the base member 13 by fitting the concave grooves 12 a to the protrusions 13 a as viewed from the back side of the base member 13. As shown in FIG. 5, two protruding spring seats 13b are formed on the back surface of the base member 13, and are pressed into each spring seat 13b and the stopper 12b with a preload maintained. A compression spring 14 is disposed as a return member.
Therefore, when the pedal tread 12 is stepped on by the driver 4, the distance from the initial position shown in FIG. 5A to the direction away from the support shaft 9 as shown in FIG. It is configured to be movable.

With the above-described configuration, according to the brake pedal 7 which is the pedal device of the present invention, the pedal tread 12 with the driver's foot 15 kept in contact with the floor of the passenger compartment 3 as shown in FIG. When the pedal is depressed, the pedal tread 12 can move in a direction away from the support shaft 9, so that the turning trajectory drawn by the driver's foot 15 and the movement trajectory drawn by the pedal tread 12 can be substantially matched. it can.
As a result, the position where the driver's foot 15 contacts the pedal tread 12 can be made substantially the same regardless of the amount of depression of the pedal tread 12, and operability can be improved without feeling uncomfortable when depressed. A brake pedal 7 can be provided. In addition, since the user does not feel a sense of incongruity, it is possible to prevent the bag from being separated from the floor surface of the passenger compartment 3 and to improve operability without feeling tired.

Yes. An urging means (not shown) and a stopper are connected to the pedal tread surface 22, and when the step by the driver's foot is not acting, it occupies the initial position shown by the solid line in FIG. In this case, displacement to a position indicated by a broken line in FIG. 8 is possible.
A holding portion 22b that forms a space portion 22a into which each support shaft 23b can be fitted is formed on the rear surface side of the pedal tread surface 22 that is not depressed by the driver. As shown in FIG. 8, the pedal tread surface 22 is engaged with the pedal tread surface 23 by fitting the respective support shafts 23b into the respective space portions 22a.
