Abstract

The invention relates to a manual obstacle surmounting wheelchair, belongs to the field of wheelchairs, and aims to solve the problems that an existing obstacle surmounting wheelchair is complex in structure and high in cost, and an original structure of an ordinary manual wheelchair is changed. The manual obstacle surmounting wheelchair disclosed by the invention comprises a wheelchair body and an obstacle surmounting device, wherein the obstacle surmounting device comprises a support unit, a drive unit and a movement unit, the support unit is arranged on the wheelchair body, the support unitis fixedly connected with the wheelchair, the drive unit is mounted on the support unit, a drive end of the drive unit is arranged on one side of the wheelchair body, the movement unit is arranged under the drive unit, and the movement unit is in transmission connection with the drive unit. The manual obstacle surmounting wheelchair disclosed by the invention is mainly used for a handicapped person to surround obstacles alone when meeting small-scale steps during going on a journey along with the wheelchair.

Description

technical field [0001] The invention belongs to the field of wheelchairs, in particular to a manual obstacle-crossing wheelchair. Background technique [0002] With the aging of my country's population, the elderly and those with lower limb disabilities account for an increasing proportion of my country's population. According to statistics, there are currently about 250 million elderly people over 60 years old in my country, and it is expected to reach 300 million in 2025, and the degree of aging continues to deepen. On the other hand, there are currently about 82.96 million disabled people in my country, accounting for about 6.34% of the total population of our country. Among them, most of the elderly and those with lower limb disabilities who have difficulty walking will choose wheelchairs as their means of transportation, or use wheelchairs to carry out daily activities alone or accompanied by family members or nursing staff. However, when encountering obstacles such a...
