Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an accelerator interlock device that disables an accelerator operation as desired in a shared vehicle such as a bus.

[Prior Art] An accelerator interlock device is used to ensure the safety of passengers in and out of a shared vehicle such as a bus.
The accelerator pedal is locked in conjunction with the opening operation of the entrance door. A conventional example of such an interlock device has a structure shown in a perspective view in FIG. 7 and a side view in FIG.

In the figure, a drive motor 71 is installed on a floor 70 of a vehicle.
The position is switched between an operating position indicated by a solid line and a standby position indicated by a two-dot chain line.

When the link 72 is in the operating position, the tip of the link 72 comes into contact with the back surface of the accelerator pedal 73, and the pedal 73 cannot rotate around the pedal hinge 74, that is, the so-called stepping operation cannot be performed. Accordingly, the pedal rod 77 rotatably supported on the body side member 75 of the vehicle via the support shaft 76, and thus the accelerator cable 78 connected to the pedal rod 77, becomes inoperable, thereby preventing erroneous operation of the engine rotation of the vehicle. You.

When the link 72 is at the standby position, the accelerator pedal 73 can be depressed, so that the accelerator cable 78 is operated via the pedal rod 77 and the engine can be operated.

[Problem to be Solved by the Invention] However, in the above-described conventional device, the accelerator pedal 73 is supported by the driving force of the driving motor 71 during its operation (at the time of locking). Therefore, the drive motor 71 needs to have a large capacity that generates enough force to support the accelerator pedal 73 in addition to the force for operating the link 72, and a large motor must be used. For this reason, a problem arises in that the foot space of the driver's seat is narrow and the appearance is impaired.

Therefore, the present invention has been made to solve the above-described problems, and the purpose is to use a small actuator such as a motor, thereby increasing the foot space of the driver's seat and improving the appearance. An object of the present invention is to provide an accelerator interlock device that can be achieved.

[Means for Solving the Problems] An accelerator interlock device according to the present invention for solving the problems described above comprises a rotating member to which an accelerator cable is connected, a pedal rod operated by an accelerator pedal, and a standby position and operation by an actuator. An operating member that is switched to two positions, a support shaft that rotatably supports the rotating member and the pedal rod on a body-side member of the vehicle, the rotating member, the pedal rod, and the operating member. And an interlocking pin for linking the pinholes provided in each of the members. Each of the pinholes regulates and permits movement of the interlocking pin with respect to each of the members, thereby turning the pedal rod in the standby position of the operating member. The pedal rod and the rotating member are integrally connected so that the rotating member moves in conjunction with the The connecting rod is formed in such a shape that the connection is released so that the rotating operation of the rod is lost.

[Operation] According to the above-mentioned means, when the operating member is moved to the standby position by the actuator, the rotating member and the pedal rod are integrally connected via the interlocking pin due to the mutual relationship between the two pin holes. Therefore, the pedal rod and the rotating member are integrally rotated about the support shaft by the depression operation of the accelerator pedal. The rotation of the rotation member allows the engine rotation to be operated via the accelerator cable.

When the operating member is moved to the operating position by the actuator, the connection of the rotating member and the pedal rod by the interlocking pin is released due to the mutual relationship between the two pin holes. Therefore, the pedal rod swings due to the depression operation of the accelerator pedal. Therefore, since the rotation of the pedal rod is not transmitted to the rotation member, the operation of the accelerator cable becomes inoperable, and malfunction of the engine rotation is prevented.

In this case, since the pedal rod swings when the accelerator pedal is depressed, unlike the conventional device that locks the depression of the accelerator pedal, the actuator does not need a force for supporting the depression force of the accelerator pedal, and the component members of the pedal do not need to support the depression force of the accelerator pedal. An unnecessary load due to stepping will not be applied.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1 showing a side view of an accelerator interlock device and FIG. 2 showing a perspective view thereof, for example, an accelerator tower 2 is installed by bolts or the like on a floor 1 of a driver's seat of a car such as a bus. . A rotation plate 4 is rotatably mounted on the upper end of the accelerator tower 2 via a support shaft 5. Note that the floor 1 constitutes a part of a body-side member of the vehicle.

One end of an accelerator cable 6 is connected to one end of the rotating plate 4, that is, an end on the vehicle front side (left end in FIG. 1). The other end of the accelerator cable 6 is connected to a throttle valve opening / closing mechanism of the engine as is well known.

The support shaft 5 is attached to a distal end of a pedal rod 8. The support shaft 5 is rotatably supported by the accelerator tower 2 through a shaft hole 4b of the rotation plate 4. The other end of the pedal rod 8 is connected to a connection hole 9a of the accelerator pedal 9.
Is engaged. The accelerator pedal 9 is attached to a pedal bracket 10 on the floor 1 so that the hinge 11 can be turned, that is, depressed.

A return spring 13 is inserted into the support shaft 5 as shown in FIG. One end of the spring 13 is locked to the distal end of the pedal rod 8, and the other end is locked to the accelerator tower 2. By this return spring 13, the pedal rod 8 is always urged in the direction of pushing back the accelerator pedal 9 (counterclockwise around the support shaft 5 in FIG. 1).

Drive motor arranged above the center of pedal rod 8
Reference numeral 15 is supported by a body 16 of the vehicle via a bracket or the like. One end (upper end) of the operating lever 17 is attached to the output shaft 15a of the drive motor 15. The lower end of the operating lever 17 is located such that the pedal rod 8 is sandwiched between the operating lever 17 and the rotating plate 4.

The drive motor 15 is rotatable in the normal and reverse directions, and the rotational drive switches the operation lever 17 between a standby position indicated by a solid line in FIG. 1 and an operation position indicated by a two-dot chain line in FIG. It is. The drive motor 15 is electrically connected so as to interlock with opening and closing of the passenger entrance door of the bus, moves the operation lever 17 to the standby position when the door is closed, and when the door is opened. The operating lever 17 is moved to the operating position.

Thus, pin holes 4a, 8a, and 17a are formed in the rotation plate 4, the pedal rod 8, and the operation lever 17, respectively. One interlocking pin 19 is inserted into these pin holes. That is, the interlocking pin 19 is laid across the rotating plate 4, the pedal rod 8, and the operation lever 17, and is prevented from falling off by a snap ring or the like (not shown). FIG. 6 is an exploded perspective view of the rotating plate 4, the pedal rod, and the operating lever 17. The pin hole 8a of the pedal rod 8 is formed to be elongated in a substantially horizontal direction. This pin hole 8a is
The movement of the interlocking pin 19 (movement in the substantially vertical direction) with the rotation of the operation lever 17 and the movement of the interlocking pin 19 (movement in the substantially horizontal direction) with the rotation of the operating lever 17 are set.

Further, the pin hole 17a of the operation lever 17 is formed in a long and slender shape that is substantially vertical. The pin hole 17a is set so as to move the interlocking pin 19 with the rotation of the operation lever 17 and to allow the movement of the interlocking pin 19 with the rotation of the pedal rod 8.

The pin hole 4a of the rotating plate 4 is formed in a substantially triangular shape. The pin hole 4a allows the movement of the interlocking pin 19 in accordance with the rotation of the operating lever 17 and the movement of the interlocking pin 19 in accordance with the rotation of the pedal rod 8 in the operating position of the operating lever 17, and the operation of the operating lever 17 The movement of the interlocking pin 19 accompanying the rotation of the pedal rod 8 at the standby position is set to be restricted.

In the accelerator interlock device described above, when the entrance door of the bus is closed, the drive lever 15 moves the operating lever 17 to the standby position. This state is shown in an enlarged view in FIG. As shown in the drawing, at this time, since the interlocking pin 19 is located at the front (the left end in the figure), the pin holes 4a, 8a, 17a for the interlocking pin 19 are formed.
, The rotating plate 4 and the pedal rod 8 are integrally connected via the interlocking pin 19. For this reason,
When the accelerator pedal 9 is depressed, the pedal rod 8 and the rotation plate 4 are integrally rotated about the support shaft 5 as the interlocking pin 19 moves in the pin hole 17a of the operation lever 17. The rotation of the rotation plate 4 allows the engine rotation to be operated via the accelerator cable 6.

When the bus door is opened, the drive motor
15 causes the operating lever 17 to move to the operating position.
This state is shown in an enlarged view in FIG. As shown in the figure, at this time, the interlocking pin 19 is positioned rearward (right end in the figure), so that the restriction of the interlocking pin 19 by the pin hole 4a of the rotating plate 4 is released, and eventually the rotating plate 4 and the pedal rod The connection by the interlocking pin 19 with 8 is released. For this reason, the depressing operation of the accelerator pedal 9 causes the interlocking pin 19 to move the operating lever 17 and both pin holes 17 of the rotating plate 4.
The pedal rod 8 swings as it moves in the areas a and 4a.
This state is shown in an enlarged view in FIG. Therefore, since the rotation of the pedal rod 8 is not transmitted to the rotation plate 4, the accelerator cable 6 becomes inoperable, and erroneous operation of engine rotation is prevented.

When the bus door is opened again, the drive motor
The operating lever 17 is moved to the standby position by the
The state shown in FIG. Therefore, the accelerator operation can be performed as described above.

According to the accelerator interlock device described above, the accelerator pedal 9 and the pedal rod 8 can swing freely during operation, so that no force is applied to the drive motor 15 by depressing the accelerator pedal 9 unlike the conventional device. For this reason, a small-capacity, small-capacity motor having enough power to switch the operation lever 17 can be used as the drive motor 15, thereby increasing the foot space of the driver's seat and improving the appearance. In addition, since the depression force of the accelerator pedal 9 is not supported, no unnecessary load due to the depression of the pedal 9 is applied to the constituent members, thereby simplifying and reducing the size of the constituent members.

Further, in this example, the drive motor 15 is arranged above the pedal rod 8, so that the space on the floor 1 can be widened and the drive motor 15 enters the blind spot of the driver, so that the appearance on the floor 1 is improved. .

The present invention is not limited to the above embodiment,
Changes can be made without departing from the spirit of the invention. For example, as an actuator, in addition to a motor,
An electromagnetic solenoid can be used.

[Advantage of the Invention] According to the accelerator interlock device of the present invention, when the operating member is moved to the operating position by the actuator, the pedal rod is swung when the accelerator pedal is depressed, so that the depression of the accelerator pedal is locked. Unlike conventional devices, there is no need for the actuator to support the accelerator pedal depressing force, so it is possible to use a small actuator that has at least the force to switch the operating member, thereby increasing the foot space of the driver's seat and improving the appearance. Can be achieved. In addition, since the depression force of the accelerator pedal is not supported, the component members are not subjected to an excessive load due to the depression of the pedal, so that the configuration members can be simplified and downsized.
