Description

Personal Electric Vehicles < RTI ID = 0.0 >

The present invention relates to a personal railway train, and more particularly, to a personal railway train which facilitates the boarding of a disabled person or an elderly person with an uncomfortable body and provides excellent driving performance and ease of use so that the rider can ascend and descend steadily, The present invention relates to a personal electric railcar having an electric motor.

Generally, when a disabled person or an elderly person who is very uncomfortable or difficult to walk alone moves, a wheelchair which is easy to move while sitting is mainly used.

The term "wheelchair" refers to a chair on which a wheel is installed so that a person who is not free to legs or an inconvenient person can move while sitting. Normally, a user sitting on a seat moves a wheel installed on both sides of a seat manually, The user pushes and holds the handle attached to the back of the seat.

The wheelchair is mainly used for intensive care patients who are difficult to move by themselves. In order to enable a stable movement while the patient is seated on the seat, usually two castor-type front wheels are provided so that the front and lower portions of the seat can be changed, Two rear wheels larger than the front wheel are installed on both sides of the seat. In the case of the rear wheel, the rotator is integrally formed on the outer side of the rear wheel so that a user sitting on the seat can rotate the wheel manually.

The conventional wheelchair has a problem that the user or the carer is inconvenienced to move the wheelchair for a long time because the user rotates the wheel manually while the user is sitting on the seat or the guard pushes the wheelchair. In addition, there is a problem in that it is not possible to move the wheelchair alone when the free activity can not be performed without help of a third party, such as an intruder, a severely handicapped person or an aged elderly person,

In order to compensate for the disadvantages of the conventional hand wheelchair as described above, it is common practice to use an electric wheelchair installed in the main body so as to drive the wheel by using an electric motor that is powered by a rechargeable battery.

Generally, an electric wheelchair is composed of a main body having a drive unit having a rechargeable battery and an electric motor, and a seat portion on which a user can sit. The main body is provided with a front wheel and a rear wheel so that the power of the drive unit is transmitted to the front wheel or the rear wheel And the seat portion includes a backrest, an armrest, and a footrest, and a control lever for controlling the driving portion is installed at one side of the armrest.

Therefore, the electric wheelchair can be moved forward, backward, leftward or rightward by a simple operation without using a large force by the control lever installed on the armrest side, and the electric wheelchair can be moved alone Because of the difficulty in moving freely by themselves, the ICU, the severely handicapped, or the elderly are using electric wheelchairs.

On the other hand, since a general electric wheel chair as described above is generally manufactured on the basis of the use of a downtown area in which the state of the road surface is generally uniform and the surface of the road surface is not steeply sloped, the body and the wheel are small and the capacity of the rechargeable battery and the electric motor is small , There is a problem that it is difficult to use in areas such as rural areas where the road surface is uneven or has a steep slope.

Therefore, in recent years, not only in urban areas, but also in areas such as rural areas where there are many uneven road surfaces and steep slopes, the patented registration No. 10-0994383, which has significantly improved driving performance compared to the existing electric wheelchair, A personal electric train such as HONA and Patent Registration No. 10-1309666 has been developed.
