Description

technical field [0001] The invention relates to the field of elderly care and disability assistance equipment, in particular to a stair climbing wheelchair and a stair climbing method. Background technique [0002] With the growth of the world's population and the increasing number of aging populations, people's research on wheelchairs for the elderly and the disabled is also increasing day by day. At the same time, the number of auxiliary equipment for the disabled is also increasing; The equipment is extremely important, and has high design requirements in terms of safety and functionality. At this point, the wheelchair's functions of climbing stairs and overcoming obstacles are particularly important. However, at this stage, wheelchairs for the elderly and the disabled are an emerging industry, and the design levels of various products vary. Many products do not have the function of climbing stairs or overcoming obstacles, resulting in single product functions and demand...
