Classification of electric climbing wheelchair

1. Walking supported stair climbing wheelchair

Stepping support type climbing wheelchair has a history of nearly one hundred years in foreign countries. After continuous evolution and improvement, it is now one of the more complex transmission mechanisms in all forms of climbing wheelchair. Its principle is to imitate the climbing action of human body, supported alternately by two sets of supporting devices, so as to realize the function of going up and down stairs. The walking support wheelchair has been widely used in developed countries.

2. Star wheel stair climbing wheelchair

The climbing mechanism of star wheel climbing wheelchair is composed of a number of small wheels evenly distributed on the Y-shaped, "five-star" or "+" shaped tie bars. Each small wheel can not only rotate around its own axis, but also revolve around the central axis with the tie rod. When walking on flat ground, the wheels rotate, while when climbing stairs, the wheels rotate together, so as to realize the function of climbing stairs.

3. Crawler stair climbing wheelchair

The stair climbing wheelchair with crawler mechanism adopts a more continuous walking mode than star wheel mechanism. When the crawler leaves the upper step or moves to the next step, it will tilt back and forth due to the deviation of gravity center. environment

Because of the absolute need to ensure the safety of the disabled and the elderly going upstairs and downstairs, the safer wheelchair will be given priority instead of the cheaper wheelchair. It is believed that with the embodiment of the reliability of the height of the step-by-step supporting wheelchair, it will gradually become the mainstream wheelchair for the disabled and the elderly in the future.
