Description

TECHNICAL FIELD The present invention relates to an electric vehicle realized as a so-called senior car or the like.

An electric vehicle for rehabilitation is provided in an electric vehicle used by a user who has difficulty walking, in which a foot pedal is provided on the front wheel, and by rotating the rear wheel, the foot pedal is rotated accordingly to train the legs and recover the function. is a vehicle.

Japanese Patent Application Laid-Open No. 2018-7703 Japanese Patent Application 2020-022950 Japanese Patent Application 2020-022951

A user who has difficulty in walking regains walking, recovers walking by himself, or recovers leg strength to the extent that he/she can share social life by using an electric vehicle, and contributes to social reintegration.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric vehicle that is realized as a so-called senior car or the like, and that can be used together with the user's own driving.

Means to solve problems

People with disabilities in the lower half of the body usually spend their days in a chair.In addition, they use electric vehicles when going out, and have very few opportunities to move or move their legs. be seen.
In order to eliminate it, a foot pedal is provided on the electric vehicle to restore leg strength.

The electric vehicle of the present invention is an electric vehicle in which a user sits on a seat and can be powered by a driving force from a motor. A clutch is built in one on each side, and unless the front wheel pedal is turned (with both feet on the pedal), the front wheel is idle and it moves forward only with the driving force of the motor.

If one foot (if the right foot cannot be moved), leave the right foot on the pedal, rotate only the left foot pedal, and move forward by combining the rotational force of the left foot with the rotational force of the rear wheel electric vehicle.
If the left foot cannot be moved, only the right foot pedal is rotated while the left foot is placed on the pedal, and the torque of the right foot is combined with the torque of the rear wheel electric vehicle to move forward.
It is characterized by having two one-way clutches on the front wheels in order to move the left and right separately.

For those with weak legs, set the speed change lever on the left side of the meter panel to a lower position, set the direction change lever on the right side of the meter panel to forward, and then adjust the accelerator on the right side to drive the electric It is characterized by adjusting the speed of the rotational force of the vehicle and advancing the rotational force of the pedal together with the rotational force of the electric vehicle.

When the speed change lever is set to 6km max and the accelerator lever is gripped 100%, the electric vehicle is set to reach a speed of 6km without turning the front wheel pedals.
With the above settings, when the user regains leg strength, turning the pedals to match the rotational force of the electric vehicle will save the battery of the electric vehicle and extend the mileage. and

With the above settings, if the pedal can be rotated more than the rotation of the electric vehicle, the assumed speed of 6 km or more can be achieved. It is characterized by

Since the above electric vehicle is for rehabilitation, speed is not required, so the length of the pedal crank is shortened by about 20%, and the pedal is set large for people with leg disabilities. do

In addition to increasing the size of the pedals, the expansion and contraction of the pedals can be adjusted to increase the area of the pedals for people with disabilities.
For example, (10 cm x 10 cm) can be stretched to (10 cm x 20 cm).
Methods for expanding the pedal widely include a bellows method, a folding method, and the like.
It is characterized by having a pedal that can extend and retract.

The electric vehicle of the present invention is characterized in that the seat can be fully rotated (360 degrees) when getting on and off, and that the user can get on and off even from directly behind the vehicle when getting on and off.

In the electric vehicle of the present invention, the seat can be easily adjusted up and down, forward and backward, to a position suitable for the user.

In the electric vehicle of the present invention, the armrests of the seats are of a flip-up type so that getting on and off is free.

In the electric vehicle of the present invention, the battery level, travel distance, speedometer, and pedal rotation speed are displayed in electric characters on the front panel.
The speed change lever and direction change lever are also displayed on the front panel.

Effect of the invention

By turning the pedals of the electric vehicle, it is possible to easily perform the exercise that could only be done in sports gyms, etc., and contribute to the functional recovery of the legs.

Even people with severe leg disabilities can freely increase the size of the pedals, so they can cope with such problems and ride this electric vehicle to contribute to functional recovery.

Even a person with a disability in one leg can ride an electric vehicle and contribute to functional recovery because the front wheel pedal operates independently.

Even if the battery runs out during outdoor driving, you can go home by pedaling and go on a long trip with peace of mind.

Sufficient use of the pedals will reduce the strain on the battery, extend battery life, and extend the range.

Even from a narrow space in the hospital room, it is possible to get on from directly behind, and an attendant becomes unnecessary.

MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a perspective view of an electric vehicle according to an embodiment of the invention. This electric vehicle 1 is realized as a so-called senior car or the like, in which a user sits on a seat 2 and can travel electrically by driving force from a motor 3 . It is to transmit to the drive shaft 6 connected to the rear wheel 5 by the transmission mechanism 4 .

Specifically, FIG. 2 is a block diagram schematically showing such a drive mechanism 4 and electrical configuration. A driving force from the motor 3 is transmitted from the output shaft 31 to the drive shaft 6 via clutches 42 and 42 and gears 43 and 44 .

The electric vehicle 1 as a so-called senior car may have a length of 1.2 m and a width of 0.7 m or less.
