Wheel/track coupled type self-balancing barrier-free wheelchair

Abstract

The invention relates to a wheel / track coupled type self-balancing barrier-free wheelchair. The wheel / track coupled type self-balancing barrier-free wheelchair consists of an upper machine frame, a lower machine frame, a main machine frame, a lower limb machine frame, an auxiliary wheel frame, an auxiliary wheel, a gravity balance mechanism and a wheel / track changing structure moving platform, wherein the upper machine frame and the lower machine frame are connected with the upper end of the main frame in a shaft driving manner and can automatically rotate around the upper end shaft of the main frame through adjustment of the gravity balance mechanism; and the lower limb machine frame is moveably connected with the lower machine frame and can automatically rotate around the outer side of the lower machine frame. By adoption of the wheel / track coupled type moving platform, the wheelchair has excellent obstacle crossing capability when climbing stairs or barriers. The wheel / track coupled type self-balancing barrier-free wheelchair has a reasonable structure, is convenient to operate and provides great convenience for travelling and daily life of people with the lower limbs disabled.

Description

technical field [0001] The invention is a wheel / shoe coupling type self-balancing barrier-free wheelchair, which belongs to a barrier-free wheelchair that can run safely and stably on flat ground, stairs and uneven roads. Background technique [0002] Self-balancing barrier-free wheelchair is a comprehensive system integrating multiple technologies such as motion mechanism, dynamic decision-making and planning, and behavior control. Among them, the star wheel barrier-free wheelchair and the crawler barrier-free wheelchair are the most representative. Barrier-free wheelchairs are an indispensable means of transportation for the elderly and paralyzed patients in their daily lives. Wheelchairs with superior performance, especially intelligent barrier-free wheelchairs, can enable them to regain their living ability and enhance their recovery while completing some daily activities. The confidence to integrate into society. [0003] The star wheel barrier-free wheelchair is curr...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects of the existing barrier-free wheelchairs such as instability, low reliability, and slow speed when climbing stairs or obstacles, the present invention provides a safe, convenient and stable climbing stairs or obstacle climbing wheelchair. The wheelchair for objects, the user can freely "walk" on flat ground, stair steps, and slopes without any help, which will provide great convenience for the daily life of the disabled
