Abstract

The invention relates to a mechanical self-powered wheelchair for walking up and down stairs, which belongs to the technical field of wheelchairs. The mechanical self-powered wheelchair comprises a seat self-balancing adjusting mechanism, a wheelchair frame, a hand wheel, crawler walking mechanisms, a multi-path power transmission system, hand wheel elevating mechanisms, guide wheel mechanisms, a one-way ratchet wheel mechanism and braking mechanisms, wherein the seat self-balancing adjusting mechanism is arranged on the upper part of the wheelchair frame; the multi-path power transmission system is arranged on the lower part of the seat self-balancing adjusting mechanism and at the middle part position of the wheelchair frame; the hand wheel elevating mechanisms are arranged on both sides of the wheelchair frame; the walking mechanisms are arranged on both sides of the lower part of the wheelchair frame; the guide wheel mechanisms are arranged on the front two sides of the wheelchair frame; the braking mechanisms are arranged both sides of the wheelchair frame close to seat handrails; and a one-way ratchet wheel is arranged at the front end of the wheelchair frame. The invention provides a mechanical self-powered wheelchair for walking up and down stairs, which is economical and reasonable in price, moves stably and continuously, has safe and reliable performance, can be used for assisting a user in walking up and down stairs without help of other people, and is convenient to operate.

Description

technical field [0001] The invention relates to a mechanical self-service wheelchair for going up and down stairs, belonging to the technical field of wheelchairs. Background technique [0002] At present, most barrier-free wheelchairs on the market are driven by motors, equipped with complex intelligent control systems and actuators, wheelchairs are heavy, difficult to maintain, limited battery life, high cost, expensive, and ordinary disabled people cannot afford to use them. A small number of low-cost mechanical barrier-free wheelchairs have problems such as single function, need for assistance from others during use, poor independence, discontinuous movement, unstable movement up and down stairs, and poor safety. A single crawler wheelchair can realize the function of going up and down stairs, but the movement resistance on flat ground is large, and it is laborious to use; while the wheeled wheelchair goes up and down stairs with large bumps and unstable movement. In ad...
