Technical Field

The invention relates to the technical field of travel equipment, in particular to a self-balancing walk-substituting wheelchair.

Background

The oldest wheelchair in china is described as a stone coffin carved by archaeologists about 1600 years before the era, while europe first describes a wheelbarrow which is actually in the middle century. The 18 th century appeared a modern wheelchair, which is composed of two large wooden front wheels, a single small wheel at the back and a chair with armrests in the middle. After the second war, the united states began to allocate a large number of wheelchairs to injuries and diseases. Nowadays, wheelchairs are slowly used in sports competitions, medical treatment, outdoor activities, and the like.

According to the national sampling survey data of the disabled, the number of the disabled people in the limbs exceeds 2000 ten thousand in China, and the research report of the aged market research and development trend of the aged population in 2025 in 2019 shows that the scale of the aged population in China shows total expansion, the utilization rate of the wheelchair is increased year by year, and the wheelchair in the current market develops in a fully automatic mode, a manual mode, a folding mode and a crawler climbing mode due to social requirements. Although the function of the wheelchair is more and more powerful, the guarantee facilities for the disabled in China are not completely popularized, and the disabled and the old people live in old communities, the channels for the disabled are rare when going out, and the roads in rural areas are uneven, so that great obstruction is brought to the traveling of the disabled.

The functions of equipment for the disabled are perfected, convenience is provided for people who are inconvenient to go out, and the method has great significance.

Wheelchairs in the market at present are various and powerful, but all play the best role under ideal road conditions, and for disabled people who go up and down slopes at stair openings, resistance is increased for family and friends who push the wheelchairs because bodies of people sitting on the wheelchairs tilt forward and backward during running. For manual wheelchairs, if the break is too steep, it may also lead to rollover. Even if the wheelchair is powered, this increases the load on the motor, and thus the life of the wheelchair is greatly reduced. On the unmodified roads in some rural areas, parts of components of the wheelchair are abraded when the wheelchair shakes in the driving process in the market, and the danger is generated for users seriously.
