Description

Stop pedal and accelerator pedal control device for vehicles for the disabled.

The present invention relates to a pedal control device for a vehicle, and more particularly, to a pedal and acceleration pedal control device for a vehicle for a disabled person used by a handicapped person who is inconvenient to use a foot to accelerate, decelerate or stop a car by manual operation. .

The driver's seat of the manual transmission vehicle is provided with an accelerator pedal, a stop pedal and a clutch pedal. The accelerator pedal and stop pedal are operated by the driver's right foot, and the clutch pedal is operated by the left foot.

However, since the disabled driver who is inconvenient to use both legs cannot operate each pedal by foot, a separate device capable of operating the accelerator pedal and the stop pedal by hand is required instead. In addition, since the operation of the clutch pedal by such a device is very inconvenient and difficult for the handicapped, it is common for the handicapped vehicle to use an automatic transmission instead of a manual transmission.

Therefore, only the accelerator pedal and the stop pedal are manipulated by hand as the stop and accelerator device, which will be described below with reference to one example of a conventional device configuration.

1 is a partial cutaway perspective view of a hand control which is now commonly used, and according to the publication No. 91-4896 disclosed in the Patent Office of the Republic of Korea, the fixing plate is rotatably connected to the steering shaft, the operation handle to the fixing plate Is attached. The operation handle is provided with a pair of links on both sides of the rotation axis, so that the link provided at the end of the operation handle is connected to the accelerator pedal, and the other link is connected to the stop pedal.

With the above configuration, when the operation handle is rotated upward, the end of the operation handle is lowered about the rotation axis, and the link presses the accelerator pedal. Thus, the car starts and accelerates. On the other hand, if the operating handle is rotated downward, the end of the operating handle is raised in reverse to the above so that its link no longer presses the accelerator pedal. However, since the other link moves along the direction of rotation of the operation handle, the link depresses or stops the vehicle by pressing the brake pedal.

However, the conventional acceleration / deceleration device described above has the following problems.

First, since the fixed plate connected to the steering shaft and the operation handle are fixed by welding, when the operation handle is used for a long time, the welded portion is likely to be damaged. If the connection between the operation handle and the fixed plate is broken, there is a serious safety problem that can not be applied to brake and cause a large accident.

In addition, the conventional fixed plate is connected to the steering shaft, there is also a problem that acts as a barrier to operating the steering wheel.

In addition, when driving at a constant speed, or stopping in a signal waiting state, such as when driving on a highway without accelerating and decelerating, there is a inconvenience in that the driver must support the steering wheel as it is rotated at a constant angle.

Accordingly, the present invention has been made to solve all the problems that the conventional acceleration and deceleration device has, and by greatly strengthening the fixing force of the fixing plate, in advance to prevent a large accident that can be caused by the connection between the fixing plate and the operation handle is broken in advance. An object of the present invention is to provide a pedal operation device for a disabled car that can be prevented.

Another object is to fix the fixing plate to a fixing portion other than a portion driven for driving a vehicle, such as a steering shaft, so that the driving plate is not obstructed.

Still another object is to maintain the state without applying force to the operation handle when driving at a constant speed or stopping for a long time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a partially exploded perspective view of a pedal operation device for the disabled according to the present invention, Figure 3 is a schematic plan view thereof, the reference is intended to clarify the position of the parts.

The stop and accelerator pedal operating device according to the present invention is roughly fixed plate 10, the rotating plate 20 rotatably connected to the fixed plate 10, the operating lever 30 and the rotating plate 20 installed on the rotating plate 20 and acceleration It consists of a pair of links 40 and 50 connected to the pedal and the stop pedal, respectively. Links 40 and 50 are only partially cut.

The fixing plate 10 shows six bolt holes 12 formed at one side thereof, and only a part of the bolts 13, which can be screwed in a proper position under an instrument panel (not shown), respectively, fitted in the holes. Fixed under the instrument panel. The rotating plate 20 can be bidirectionally rotated at a predetermined angle by an operation of the handle 32 connected to the lever 30 in a state of being coupled to the fixed plate 10.

The fixed plate 10 and the rotating plate 20 are combined as follows. That is, it is fixed to the cylindrical bush 23 in the vertical direction with the rotating plate 20, the shaft bolt 11 is fitted through the bush 23 is fastened by the nut (15). The axial bolt 11 is fitted in the direction perpendicular to the plate through the bolt hole 14 formed in the fixed plate (10). In addition, the bearing 24 is installed on the outer circumference of the bush 23 so that the bush can be freely rotated from the rotating plate 20. In the present embodiment, the bearing 24 is a ball bearing. As a result, the rotating plate 20 is in a state in which the rotating plate 20 can be freely rotated in the left and right directions while being spaced in parallel with the fixed plate 10, and the rotation of the rotating plate 20 is performed by the handle 32 as described above. It is made with the central axis.

The end pipe 22 is fixed to both sides of the rotating plate 20 by a U bolt 21 or a fastening means such as welding, and the lever 30 and the links 40 and 50 are connected to each other through the end pipe 22. Each combined. Since a general method for connecting the shaft is used here, a detailed illustration or explanation thereof is omitted. The direction of movement of the handle 32 and the links 40 and 50 are clearly explained by arrows, respectively. According to the invention, the accelerator pedal link 40 is connected to the accelerator pedal 3 and the stop pedal link 50 is connected to the stop pedal 4 (see FIG. 4).

On the other hand, the present invention provides a means for fixing the operating lever 30 in the corresponding position when stopped or running at a constant speed.

First, the structure of the means which fixes the operation handle 30 at the time of constant speed pouring is as follows. The first electromagnet 60 is provided in an annular shape on the outer circumference of the bush 23 and the bearing 24 of the rotating plate 20. The first electromagnet 60 can be magnetized, for example, by the operation of the first switch 34 provided near the handle 32. When the first electromagnet 60 is magnetized, the fixed plate 10, which is a metal material, is attached to the rotating plate 20 with a force proportional to the magnetic force.

On the other hand, the configuration of the means for fixing the operating lever 30 at the time of stopping is as follows. The rod-shaped second electromagnet 70 is fixedly installed on the plane of the rotating plate 20. The second electromagnet 70 can be magnetized, for example, by the operation of the second switch 33 provided near the handle 32. Meanwhile, a fan-shaped ratchet 90 is fixed to the bottom of the fixed plate 10 by bolts, and a U-shaped locking hole 80 is provided on the upper surface of the rotating plate. The catch 80 may be rotated about the pin 81, and may be elastically moved by the spring 82. Reference numeral 31 is an electric wire for supplying current to each of the electromagnets (60, 70).

The catching hole 80 is disposed to be close to the deceleration electromagnet 70, and the tip is installed to be close to the teeth of the ratchet 90 screwed to the fixing plate 10 (see FIG. 3). One end of the coil spring 82 is connected to one end of the locking hole 80, the other end is connected to the rotating plate (20). As a result, when electric power is supplied to the electromagnet 70, the locking hole 80 is rotated by winning the force of the spring 82 about the pin 81, and is inserted into a predetermined position of the ratchet 90 to allow the rotating plate 20 to be rotated. To prevent relative rotation with respect to the fixed plate (10).

4 is a configuration diagram showing an installation state of a pedal operation device according to the present invention.

Each link 40, 50 is connected to the accelerator pedal 3 and the stop pedal 4 by a predetermined link mechanism. When the lever 30 and the handle 32 are positioned below the steering wheel 1, the fixing plate 10 is fixed to the bottom of the instrument panel 2. Although not clearly shown, the handle 32 is installed in a position similar to a conventional turn indicator (or wiper) control lever or headlight control lever to be easily adjusted by hand.

Hereinafter, the operation of the present embodiment configured as described above will be described in detail with reference to the drawings.

First, the lever 30 of FIG. 2 and the rotating plate 20 integrated therewith are rotated about the shaft bolt 11 when a rotational force is applied to the handle 32 in the direction of an arrow. Accordingly, the stop pedal link 50 interlocked with the rotating plate member 20 is lowered in the direction in which the stop pedal 4 is pressed, and the accelerator pedal link 40 is raised. Similarly, when the operating lever 30 of FIG. 3 and the rotating plate 20 integrated therewith are applied to the handle 32 in the direction of the arrow B, the accelerator pedal link 40 descends in the direction of pressing the accelerator pedal 3. Done. Here, a conventional link mechanism is provided for pressing one side (eg, an accelerator pedal) so that the other side (eg, a stop pedal) is not pulled over a certain distance. That is, it is configured so that only the accelerator pedal can be continuously pressed without pressing the stop pedal.

Here, the driver magnetizes the first electromagnet 60 for the accelerator pedal by turning on the first switch 34 when the operating lever 30 is in a constant acceleration position when the driver can travel at a constant speed as on a highway. (磁化) Then, the rotating plate 20 integrated with the first electromagnet 60 is fixed to the fixed plate 10 in a state of being rotated at a predetermined angle. Therefore, even if the driver is not applying a force to the operation lever 30, the operation lever 30 is maintained in a rotated state can be easily operated. When the driver needs to change the driving speed, the driver may turn off the first switch 34 to release the fixed state of the rotating plate 20 and the fixed plate 10 and then operate the operation lever 30 again.

In addition, when the driver presses the stop pedal 4 as much as required to rotate the operation lever 30 in the direction of the arrow when the vehicle is stopped, the driver can use the second stop pedal for maintaining the state for a certain time. The switch 33 is turned on to magnetize the second electromagnet 70. One end of the locking hole 80 by the magnetized second electromagnet 70 is rotated in a direction to be fixed to the electromagnet 70 around the pin 81 to overcome the compressive force of the coil spring 82. Then, the distal end of the catch 80 is snapped to a predetermined position of the teeth of the ratchet 90. As a result, the rotating plate 20 integrated with the locking mechanism 80 is fixed in a state in which the rotating plate 20 is rotated at a predetermined angle with the fixing plate 10. Therefore, even if the driver does not apply the force to the operation lever 30, the operation lever 30 is maintained in a rotated state it is possible to easily maintain the stopped state of the vehicle. When the driver tries to continue normal driving again, when the second switch 33 is turned off, the locking hole 80 is spaced apart from the ratchet 90 by the compression force of the coil spring 82, and the rotating plate 20 is fixed plate 10. It becomes a state which can be rotated again from), and it becomes possible to operate the operation lever 30.

Here, the reason for using the ratchet 90 and the locking mechanism 80 at the time of stopping instead of the method of fixing the operation handle 30 only by the magnetic force at the time of acceleration is that the range of the automatic transmission is "D ( drive) "state. That is, when driving at a constant speed, no external force is applied to the operation handle 32, but even when the vehicle is stopped, most of the automatic shift lever is not changed in the "D" range as in the case of driving, so that the operation lever 30 does not move forward. Because you will receive. That is, since only the magnetic force by the first electromagnet 60, which is the stopper of the accelerator pedal link 40, is insufficient to fix the operating lever 30 firmly, the ratchet 90 and the latch 80 may be fixed. Means are used.

On the other hand, the stopping means (first electromagnet 60) of the accelerator pedal 3 which can be operated by a relatively weak operating force is absolutely necessary under the following circumstances. That is, when the driver is driving at a constant speed, or suddenly to accelerate or stop the vehicle, by turning the emergency stop, that is, operating lever 30 without having to take an intermediate action such as switching off the switch The stop pedal 4 can be operated. This is possible because the rotating plate 20 and the fixed plate 10 are merely in surface contact by the magnetic force of the electromagnet 60, and are means provided for safety against accidental situations on the road.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.

As described above, according to the present invention, the driver is not provided with obstacles in driving operation by the conventional stop and accelerator pedal apparatuses because the fixed plate is installed on the instrument panel instead of the steering shaft.

In addition, the stationary plate is not welded to the steering shaft and fixed to the instrument panel by bolting, so that the fixing force of the device is greatly enhanced to enable the driver to drive safely. That is, the welding connection between the stationary plate and the rotating plate is broken, and it is possible to prevent the occurrence of a large accident in advance.

In addition, even a vehicle having a steering system capable of adjusting the height or angle of a steering wheel, which is widely used in recent years, can be installed and operated without degrading the function of the system.

In addition, it is possible to maintain the operated state without applying force to the operation lever when driving at a constant speed or stopping for a certain time by the electromagnet or the ratchet means. Make it easy to operate. This function is particularly useful in the following cases. In other words, people with disabilities who cannot use both legs should control their right arm stop pedal, shift lever, and steering wheel because the left arm must be taken out of the car window when paying the fare at the toll gate or underground parking lot of the expressway or receiving a ticket. do. At this time, the stop pedal can be held firmly by simply operating the switch located on the operation lever.
