The stair-climbing wheelchair was developed based on ordinary wheelchairs, which could be used as a mobility tool. But when encountering obstacles, such as stairs and bumps, they are difficult to cross, hence the creation of the stair-climbing wheelchair.

The development of stair-climbing wheelchairs
Wheelchairs are an important mobility tool for the elderly and physically disabled, and the market demand has grown in recent years. However, the wheelchairs commonly used in the market can only be used on flat ground, and only a few of them can climb stairs and turn over barricades, thus greatly hindering the convenience of wheelchair use. In addition, the disabled and the elderly are eager to live independently, so the performance and quality of wheelchairs must be continuously optimized. At this stage, many researchers have gradually strengthened their research on stair-climbing wheelchairs. At present, China's artificial intelligence technology, sensor information fusion technology and many other advanced technologies have achieved rapid development and good results. Therefore, they led to a new achievement in the development of stair-climbing wheelchairs, and gradually turned to human-machine integration.
The structures of stair-climbing wheelchairs
1、Planetary wheel structure: the main structure of the domestic stair-climbing wheelchair is the planetary wheel structure. This structure of the stair-climbing wheelchair is simple, plus its self-locking mechanism can ensure that there is no tilt when going up and down the stairs. However, this kind of stair-climbing wheelchair lacks the adaptability for stairs, thus, the comfort and reliability of the relevant users cannot be effectively met.
2、Crawler wheel structure: for the crawler wheelchair, the crawler wheel structure is mainly used to ensure the continuity of going up and down the stairs. However, this kind of crawler wheel stair climbing cannot achieve a balanced conversion between inclined and flat surfaces. And its overall structure is bulky, which can cause great damage to the edge of the stairs. Plus it moves with excessive resistance, difficult steering work and large energy loss, thus greatly hindering the use and popularity of this kind of stair climbing wheelchair.
3、Leg and foot structure: For the leg and foot structure of the stair-climbing wheelchair, its main principle is to imitate the movement of people going up and down stairs. It uses one or more groups of alternating movements to achieve the effect of climbing stairs, and can be effectively applied to various stair structures. However, this method has a high center of gravity and the possibility of tipping over. Coupled with its difficult control and overly complex structure, it requires a long period of optimization and improvement before it can be used on a large scale.
Today, the technology for manufacturing stair-climbing wheelchairs in our factory has been well developed. And stair-climbing wheelchairs are highly intelligent and are gradually converging to international standards of uniformity. For the choice of a wheelchair, our factory is an ideal choice. The above is for you to tell the basic introduction of manual wheelchairs, I hope it will be helpful to you. For more information, please visit other sections of this site.
