Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle stopping device which is mainly used to enable people with poor walking ability, such as elderly people, to move easily.

0002

BACKGROUND OF THE INVENTION Conventionally, this type of vehicle has been constructed in the form of a scooter, with a pair of left and right handle grips, which can be gripped by an operator seated on a seat, while driving the vehicle. It is known that a speed regulating lever for adjusting the traveling speed is arranged so that it can be gripped together with the handle grip, and a lever or pedal for performing a braking operation is provided on the handle or step.

0003

However, in the conventional vehicle described above, the stopping operation is performed by operating a brake lever or pedal, or by holding and not operating the speed regulating lever. However, if an elderly person is driving the car, for example, when they have to stop the car in an emergency, they may get upset and instead of applying the brakes, they may forcefully grip the speed control lever toward accelerating. was there.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a vehicle stopping device that can ensure safety even if the driver accidentally grips the speed regulating lever too hard to increase the speed. purpose.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the vehicle stopping device according to the present invention includes a driving speed setting device that can be freely operated by both grips in the vicinity of at least one of a pair of left and right steering handle grips. A speed regulating lever is disposed, and the speed regulating lever and the control means are linked via an actuating means that operates the control means in conjunction with the operation of the speed regulating lever toward a higher speed than the set speed. The features are as follows. The functions and effects of this characteristic configuration are as follows.

[0006]

[Operation] That is, even if the speed governor lever is accidentally operated to a higher speed than the set speed, the braking means is activated via the actuating means, so that the vehicle can stop running.

[0007]

[Effects of the Invention] Therefore, when an emergency stop is required, even if the speed regulating lever is hurriedly squeezed to the side of the high speed, the vehicle will still be stopped, making it highly safe.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings.

FIG. 4 shows a small electric vehicle for people with walking disabilities as one type of such vehicle. This small electric vehicle has front wheels 2 that are steered by operating a steering handle 1.
A pair of left and right rear wheels 4 driven by an electric motor 3 are supported by a vehicle body frame 5, and a driver's seat 6 is provided on the vehicle body frame 5 above the rear wheels 4. Further, as shown in FIG. 4, a basket 8 equipped with a hand strap is provided on the support frame 7 of the operating handle 1 so as to be detachable by inserting it into a locking structure using a leaf spring. The electric motor 3 is connected to a control device 9 and a battery 10 disposed below the driver's seat 6.

As shown in FIG. 3, the control handle 1 includes:
It is equipped with handle grips 1A, 1A made of a round pipe A with left and right sides bent into a U-shape, and a speed regulating lever 11 for setting the traveling speed that can be gripped and operated together with the left and right handle grips 1A, 1A, respectively. 11 are pivotally supported so that they can freely swing up and down. As shown in FIG. 1, the drive arm 1 swings together with the regulating levers 11, 11
2 and the driven shaft 13 of the potentiometer 13 for speed setting.
The potentiometer 13 is connected to the control device 9 via the link mechanism 14, and the potentiometer 13 sends its output signal to the control device 9.
Connected to input. In addition, the speed regulating lever 11,1
1 is a handle grip 1A, 1 by a spring 15.
When the round pipe A of the operating handle 1 and one end 12a of the drive arm 12 come into contact with each other, the spring 15 restricts the position away from the handle grips 1A and 1A. There is. This drive arm 1
2, the output signal from the potentiometer 13 when the position is regulated is set to the traveling stop state, and the speed regulating lever 11
, 11 closer to the handle grips 1A, 1A, the electric motor 3 is driven and controlled based on the output signal from the potentiometer 13 so that the traveling speed is increased approximately in proportion to the operation amount when the handle grips 1A, 11 are brought closer to the handle grips 1A, 1A. The control device 9 is set accordingly. On the other hand, an elastic rubber 16 is fixed to the other end 12b of the drive arm 12, and the speed regulating lever 1
When gripping 1 and 11 to the high speed side, the drive arm 12
The other end 12b and the round pipe A of the operating handle 1 are configured to be regulated by the elastic rubber 16. Therefore, the maximum traveling speed is determined by the drive arm 1 through the elastic rubber 16.
2 and the round pipe A of the operating handle 1.

Furthermore, an electromagnetic friction brake 18 as a braking means operated by a signal from the control device 9 is interposed in the transmission case 17 that links the electric motor 3 and the rear wheel 4. A manually operated traveling clutch (not shown) is interposed between the electromagnetic friction brake 18 and the rear wheel 4, and a manual brake lever is provided near the steering handle 1 so that the brake lever can be held together. A manual friction brake 20 operated at 19 is arranged to act on the axle of the rear wheel 4. As shown in FIG. 1, the electromagnetic friction brake 18 is activated by a control device 9 based on a detection signal of an ON operation of a limit switch 21 disposed below the front of the round pipe A of the operating handle 1.
The brake is operated by the driver. The limit switch 21 is activated by the compressive deformation of the elastic rubber 16, which causes the drive arm to move beyond the contact position between the elastic rubber 16 and the round pipe A of the operating handle 1 when the speed regulating levers 11, 11 are operated toward the maximum speed. 1
The other end 12b of the round pipe A is set and arranged so that it can be inserted and operated when the pipe A moves close to the round pipe A. Therefore, if the driver grips the speed regulating levers 11, 11 strongly in a hurry, the limit switch 21 is turned on and operated, and as a result, the electromagnetic friction brake 18 is activated and the vehicle stops running. Note that, based on the result of detection of the turning-on operation of the limit switch 21, the control device 9 controls the drive of the transmission motor 3 to also be stopped. Here, the limit switch 21 and the control device 9 constitute an actuating means 22 for operating the braking means.

Next, the driver's seat 6 will be briefly explained. As shown in FIG. 6, the driver's seat 6 is supported so as to be swingable around a vertical axis P, and is configured to be fixed and changeable in the forward direction and laterally on both the left and right sides. That is, a vertical shaft 26 protruding from the lower surface of the seat frame 25 below the driver's seat 6 is loosely fitted and supported on a boss portion 24 provided upright on a cover frame 23 that covers the battery 10, etc., and a seat support provided on the upper portion of the boss portion 24 is supported. A lock lever 31 is pivotably supported on the seat frame 25, and a lock member 30 is engaged in a notch groove 29 formed in the front and left and right side parts of the seat frame 27 and provided with a rubber bush 28 in the notch. It is provided and configured so that it can be oscillated. Place the driver's seat 6 in a predetermined position (
(forward facing or left/right sideways), then lock member 3
0 into the notch groove 29, the driver's seat 6 is fixed. As shown in FIG. 7, the rubber bush 28 is attached so that the width of the notch groove 29 is narrower than the thickness of the locking member 30, so the driver's seat 6 is fixed without wobbling.
