Description

  The present invention relates to pedals used in various industrial, agricultural, and commercial vehicles, and more particularly to a vehicle operation pedal device that is integrally provided with a brake operation mechanism and an accelerator operation mechanism.

  Conventionally, an operation pedal of an automobile or the like is an apparatus in which an accelerator pedal and a brake pedal are arranged in parallel on a floor surface of a driver's seat, and the driver selects and steps one of them to control driving and braking of the vehicle. is there. Generally, both the accelerator pedal and the brake pedal are operated with just the right foot, and when switching the vehicle from the running state to the braking state, the driver removes the right foot from the accelerator pedal, and the upper part of the brake pedal arranged in parallel , And depress the brake pedal to brake the vehicle.

  Therefore, when sudden braking is performed from the traveling state, the vehicle runs idle while moving the right foot from the accelerator pedal to the brake pedal, and the braking distance becomes long.

  Further, for example, when the vehicle starts, travels, or stops, the driver may make a mistake in stepping on the pedal that the driver steps on.

  In order to solve the above problems, an auxiliary pedal is connected to a brake pedal that is depressed, an accelerator pad that is operated laterally is disposed on the auxiliary pedal, and a brake having an accelerator mechanism that is driven by the accelerator pad. A pedal device (see, for example, Patent Document 1) has been previously disclosed.

Japanese Patent No. 4249010

  However, the operation of the brake pedal described in Patent Document 1 operates the accelerator pad by rotating the toe side outwards (external rotation) with the heel as a fulcrum, so fatigue is applied to the ankle during long-time driving. As the accelerator pad can be pressed even with a weak force in order to solve this problem, the tilt of the vehicle when traveling on a rough road There was also a problem that the toe unexpectedly pressed the accelerator pad against the driver's will.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicular operating pedal device that can prevent a pedal from being stepped incorrectly and erroneously operated.

  Therefore, the vehicle operation pedal device according to the present invention includes a brake pedal that the driver depresses, a shaft portion that projects from the front of the brake pedal toward the driver side, and a bearing that is pivotable to the shaft portion. An accelerator pedal for placing and turning the operated foot, and a speed adjusting mechanism capable of adjusting a traveling speed in accordance with a turning distance of the accelerator pedal, the front surface of the brake pedal, and the accelerator pedal The first feature is that the back surface of the vehicle is inclined toward the accelerator closing direction.

  A second feature is that a biasing means for biasing the accelerator pedal in the accelerator closing direction is provided.

  Furthermore, a sliding part is provided in the brake pedal or the accelerator pedal, and the third feature is that the accelerator pedal rotates through the sliding part.

The present invention has the following excellent effects.
(1) Since the brake pedal is depressed and the accelerator pedal is rotated and operated, the operation directions of acceleration and braking of the vehicle are differentiated, and erroneous operations can be reduced.
(2) Since the front surface of the brake pedal and the rear surface of the accelerator pedal are inclined toward the accelerator closing direction, the accelerator pedal can be rotated in the accelerator closing direction simultaneously with the depression of the brake pedal. Therefore, there is no time delay in operation, that is, there is no idle travel distance, and the braking distance and time of the vehicle can be shortened.
(3) The accelerator pedal is provided with an urging means that is urged in the accelerator closing direction, and a force greater than a predetermined force is required for the turning operation. Therefore, the turning operation is promoted in the accelerator opening direction by the tilting or shaking of the vehicle. Can be prevented.
(4) In order to rotate the accelerator pedal on which one foot is placed, it is possible to operate by internal rotation and external rotation of the entire one foot from the thigh to the toe, and internal rotation and external rotation. Therefore, it is possible to prevent fatigue from accumulating on a part of the foot.

BRIEF DESCRIPTION OF THE DRAWINGS (a) which demonstrates the accelerator open state of one Example of the operation pedal apparatus for vehicles which concerns on this invention is a top view, (b) is a front view. It is the sectional view on the AA line of FIG. FIG. 2A is a plan view and FIG. 2B is a front view for explaining a state where acceleration is maximum in the accelerator open state of one embodiment of the vehicle operating pedal device according to the present invention. (A) which shows the other Example of the operation pedal apparatus for vehicles which concerns on this invention is a top view, (b) is a front view.

  Hereinafter, although an embodiment of the invention is described based on an example shown in a drawing, the present invention is not limited to this. The accelerator closing direction in the text indicates the clockwise direction, and the accelerator opening direction indicates the counterclockwise direction.

  The vehicle operation pedal device 1 according to the present invention is provided so as to be operated with a right foot in front of the driver on the floor of the driver's seat, and as shown in FIG. The accelerator pedal 3 is rotatably supported. The brake pedal 2 is provided with a sliding portion 5 so that the accelerator pedal 3 can be smoothly rotated. In addition, a speed adjusting mechanism 7 that can adjust the traveling speed of the vehicle corresponding to the turning distance of the accelerator pedal 3 is provided.

  As shown in FIG. 1A, the brake pedal 2 is a disk made of metal such as aluminum or iron inclined toward one end, and a brake arm 8 is integrally provided on the back surface 2b. Here, the brake pedal 2 is formed with a predetermined inclination angle toward an accelerator closing direction of an accelerator pedal 3 to be described later. The brake arm 8 operates a master cylinder (not shown) that converts a pedaling force received by the brake pedal 2 into hydraulic pressure and transmits a braking force to a brake cylinder (not shown) of each wheel. As long as it has the intensity | strength which can be operated stably, multiple pieces may be provided. These brake mechanisms including the brake arm 8 can use the same mechanism as a conventional brake mechanism. The rear surface 2b of the brake pedal 2 is formed so as to be parallel to the front surface 2a as shown in FIG. 1A, and the brake pedal 2 is formed in a disk shape, but is limited to a disk shape in particular. For example, a metal plate having a rectangular shape, a triangular shape, or an elliptical shape may be used, and the back surface 2b may not necessarily be parallel to the front surface 2a.

  As shown in FIG. 1B, the brake pedal 2 has an arc-shaped groove 52 on the front surface 2a side, and a plurality of rollers 51 are disposed in the groove 52. The brake pedal 2 has an accelerator pedal stopper 6 attached to the front surface 2a at a predetermined angle and is attached in a reverse C shape. The accelerator pedal 3 is brought into contact with the side surface of the accelerator pedal 3 in a certain angular range. It can be turned. Since the throttle wire 71 of the speed adjusting mechanism 7 to be described later is pulled out from the protective pipe 72 by the arc length of this angle range, the mounting angle of the accelerator pedal stopper 6 is set to a suitable angle for each vehicle.

  As shown in FIG. 3, the brake pedal 2 has a cylindrical portion 23 into which the shaft portion 4 is inserted at the lower end, and a spherical hollow in which the ball portion 41 of the shaft portion 4 is fitted inside the cylindrical portion 23. A portion 21 is formed. On the front surface 2a side of the brake pedal 2, a hollow portion 21 is formed, and an annular rod insertion hole 22 into which the rod portion 42 of the shaft portion 4 can be inserted is formed. The rod insertion hole 22 is formed so that the rod portion 42 has a certain amount of play. The hollow portion 21 is filled with a lubricant such as grease so that the ball portion 41 moves smoothly. By screwing the lid 9 into the inner surface of the cylinder portion 23, the shaft portion 4 is prevented from moving in the braking operation direction of the brake pedal 3.

  The accelerator pedal 3 is made of metal such as aluminum or iron, and as shown in FIG. 2, a cross-sectional view having an inclined surface with the same angle as the front surface 2a of the brake pedal 2 is formed in a substantially trapezoidal shape on the back surface 3b. . The front surface 3a of the accelerator pedal 3 is provided with a plate-shaped heel receiving portion 31 at the lower end portion that protrudes from the front surface and curves downward, and fits to the heel of the foot. A shaft 4 serving as a fulcrum for the rotation of 3 is inserted. As shown in FIG. 3, a male screw is formed on the rod portion 42 of the shaft portion 4, and a nut is screwed and fixed. The left and right end portions of the accelerator pedal 3 are provided with a plate-like operation portion 32 protruding in front, and the driver's right foot 10 is brought into contact with the operation portion 32 to rotate the accelerator pedal 3. It is possible. The accelerator pedal 3 is provided with a non-slip process 33 by attaching a rubber sheet or the like.

  The shaft portion 4 is made of a metal such as aluminum or iron, and as shown in FIG. 3, a ball composed of a rod portion 42 having a ball portion 41 on one end side and a female screw formed on the other end side. It is a joint. As described above, the shaft portion 4 is pivotable with respect to the brake pedal 2 by the ball portion 41 being supported by the hollow portion 21 and can be slightly swung back and forth. The accelerator pedal 3 is inserted and assembled. With this structure, the accelerator pedal 3 can be rotated with respect to the brake pedal 2 and can be slightly swung back and forth. As shown in FIG. 3, a torsion spring 11 is provided between the front surface 2 a of the brake pedal 2 and the back surface 3 b of the accelerator pedal 3, and one end side of the torsion spring 11 is the front surface of the brake pedal 2. By fixing to 2a and fixing the other end side to the accelerator pedal 3, the accelerator pedal 3 is urged | biased in the accelerator closing direction. For this reason, a force of a predetermined level or more is required to rotate the accelerator pedal 3 in the accelerator opening direction, and it is difficult to operate only by an annulus internal rotation of the ankle. Need. Therefore, it is possible to prevent the fatigue from concentrating on the ankle by operating with one foot as a whole and to enable the accelerator operation for a long time. Further, when the operating force in the accelerator opening direction becomes zero due to the biasing force of the torsion spring 11, the accelerator pedal 3 always returns to the accelerator closing direction, that is, the accelerator non-operating position regardless of the rotation position of the accelerator pedal 3. be able to.

  As shown in FIG. 1, the sliding portion 5 is provided in a state in which part of the sliding portion 5 protrudes from the groove portion 52 of the brake pedal 2. It is comprised from the holding | suppressing part 53 which fixes both ends. As shown in FIG. 3, the roller 51 can contact the back surface 3 b of the accelerator pedal 3 to smoothly rotate the accelerator pedal 3. In addition to such a structure, the sliding portion 5 is provided with, for example, the sliding portion 5 on the back surface 3b of the accelerator pedal 3, and uses, for example, a ball bearing 51a instead of the roller 51. Further, as shown in FIG. The rear surface 3b of the accelerator pedal 3 can be smoothly rotated with respect to the front surface 2a of the brake pedal 2 such that the groove portion 52a and a plurality of ball bearings 51a are provided on the rear surface 3b of the brake pedal 2. Any one can be used as long as the coefficient of dynamic friction becomes small when rotating up, and any mode can be used.

  The speed adjusting mechanism 7 includes a throttle wire 71 and a protective pipe 72 that protects the throttle wire 71, temporarily fixed to the floor of the driver's seat, and fixed to the brake pedal 2 at the other end. Is done. One end of the throttle wire 71 is fixed to the accelerator pedal 3, and the other end is connected to an engine throttle valve (not shown). The throttle wire 71 adjusts the opening degree of the throttle valve by the turning operation of the accelerator pedal 3, and the traveling speed of the vehicle is adjusted. Since the protective pipe 72 bends when the brake pedal 2 is depressed, it needs to have appropriate flexibility. Therefore, the protection pipe 72 can be configured to connect the flexible member 73 to a part of the pipe that does not have flexibility, in addition to using a member that has flexibility.

  The operation of the vehicle operating pedal device 1 configured as described above will be described. First, the positional relationship shown in FIG. 1 is a non-acting position in the brake and the accelerator, and the brake pedal 2, the accelerator pedal 3, and the speed Each mechanism such as the adjusting mechanism 7 is always urged so as to be in the inoperative position. In this state, as shown in FIG. 1, the driver's right foot 10 is placed on the accelerator pedal 3 to perform brake and accelerator operations. In addition to adjusting the brake arm 8 so that the brake pedal 2 does not act with the right foot 10 lightly placed, for example, one end of a coil spring is attached to the brake arm 8 or the other end is attached upward, or the rear surface 2b of the brake pedal 2 It is preferable that the brake pedal 2 is biased in a direction opposite to the operation direction of the brake, such as providing a coil spring between the floor surface of the driver's seat.

  When the driver's right foot 10 is rotated or moved in the left direction while the engine is being driven and the side surface of the driver's right foot 10 presses the operation portion 32, the accelerator pedal 3 moves to the left with the shaft portion 4 as the center. As shown in FIG. 2 (b), the throttle wire 71 fixed to the accelerator pedal 3 is pulled out from the protective pipe 72, and the engine throttle valve is opened to accelerate the vehicle. Further, as shown in FIG. 4B, by rotating the accelerator pedal 3 to a position where the side surface of the accelerator pedal 3 comes into contact with the accelerator pedal stopper 6, the pull-out length of the throttle wire 71 is maximized and the maximum acceleration can be obtained. it can. That is, the throttle wire 71 is pulled out by pressing the operating portion 32 of the accelerator pedal 3, and the strength of the accelerator is determined. Therefore, the driving state of the accelerator can be arbitrarily adjusted depending on the rotation or movement of the right foot 10 of the driver. Is possible. At this time, the ankle may be rotated and operated with the heel as a fulcrum. However, since fatigue concentrates on the ankle, it is preferable to drive with less fatigue by rotating the entire right foot from the knee, more preferably the thigh. be able to.

  In this way, the accelerator pedal 3 is rotatably supported by the shaft portion 4. As shown in FIG. 1A, since the plurality of rollers 51 are fixed to the inclined surface of the brake pedal 2, the contact surface of the roller 51 and the accelerator pedal 3 is the roller 51 as shown in FIG. A level difference d is generated every time. Therefore, it is preferable that the accelerator pedal 3 that contacts the roller 51 can also swing back and forth by the level difference d, and the back surface of the accelerator pedal 3 can be contacted for each roller 51 by the ball portion 41 of the shaft portion 4. Yes. The step d has a correlation with the inclination angle of the front surface of the brake pedal 2 and the back surface of the accelerator pedal 3, and accommodates the ball portion 41 and the ball portion 41 that allow the accelerator pedal 3 to swing back and forth by the step d. The required diameter of the hollow part 21 is also determined.

  Next, the braking operation of the vehicle will be described. The positional relationship indicated by the solid line in FIG. 2A is the brake inactive position and the vehicle is running. At this time, the accelerator pedal 3 is rotated to the operating position as shown in FIG. 2 (b). When the accelerator pedal 3 is stepped on strongly in this state, the front surface 2a of the brake pedal 2 and the rear surface 3b of the accelerator pedal 3 are inclined toward the accelerator closing direction, so that the brake pedal 2 is shown in FIG. And the accelerator pedal 3 is rotated in the accelerator closing direction. In other words, since the pedal force of the accelerator pedal 3 is provided with an inclination on the front surface 2a of the brake pedal 2 and the rear surface 3b of the accelerator pedal 3, the force pressing the brake arm 8 is decomposed in the inclination direction, and is decomposed in the inclination direction. The applied pedaling force causes the accelerator pedal 3 to rotate in the accelerator closing direction. Therefore, the vehicle can be braked and the traveling operation can be stopped instantaneously. Moreover, although the force which rotates the accelerator pedal 3 with respect to a driver | operator's pedaling force is weak, since the sliding part 5 is provided as mentioned above, even with a weak force, the accelerator pedal 3 is fully rotated in an accelerator closing direction. be able to. In addition, since the accelerator pedal 3 is urged in the accelerator closing direction by the torsion spring 11, the accelerator pedal 3 can be instantaneously moved to the accelerator closed state as shown in FIG. In this way, the accelerator pedal 3 is depressed to perform the brake operation, and at the same time, the acceleration of the vehicle is surely released, so that the vehicle can be braked without any time delay in operation.

  In addition, in the present invention, it is possible to freely change the design and the like of the shape and structure of each part, the change of material, and the change of usage mode, etc. within a range not changing the gist of the present invention. For example, the speed adjustment mechanism 7 may include an electronic control mechanism that detects the rotation angle of the accelerator pedal 3 and operates the throttle valve of the engine. Also, for example, since the ball joint contains a lubricant, a dust cover is used to prevent the lubricant from flowing out of the ball joint or to prevent external dust or moisture from entering the ball joint. May be provided.
