Compound self-balancing electrically powered wheelchair and using method thereof

Abstract

The invention discloses a compound self-balancing electrically powered wheelchair and a using method thereof. Present crawler-type stair-climbing wheelchairs on the market has the problems that crawler replacement is relatively troublesome, the turning in narrow corridor is not flexible, the safety is influenced due to higher sitting position of a person in a stair-climbing process, and the like.The compound self-balancing electrically powered wheelchair disclosed by the invention comprises a chair rack, a balance proceeding module, a crawler chassis module, a seat levelling module, a rear support wheel module and a control module, wherein the balance proceeding module comprises a balance wheel bracket and balance wheels; the crawler chassis module comprises a revolving axle, an overturning axle, a motor installation bracket, a crawler adjusting electric rod and two unilateral crawler components; the seat levelling module comprises a backrest main body, a cushion main body, first gears, gear racks and a levelling driving component. According to the compound self-balancing electrically powered wheelchair and the using method thereof, a mode of levelling a rear end is adopted in thestair-climbing process, so that the center of gravity in the stair-climbing process can be effectively lowered, and the safety is improved; a crawler-disassembly auxiliary part is designed in the crawler chassis module, thereby greatly improving replacing efficiency of crawlers.

Description

technical field [0001] The invention belongs to the technical field of electric wheelchairs, and in particular relates to a composite self-balancing electric wheelchair. Background technique [0002] With the increasing aging of our country, the elderly with inconvenient legs and feet are gradually increasing, and the disabled population caused by traffic accidents, production accidents and natural disasters has increased year by year in recent years, and the two account for a certain proportion of the population structure. [0003] In the residential buildings of daily life, most of the low-rise buildings are not equipped with elevators and other upstairs facilities, and the existing climbing tools on the market have various deficiencies, so it is necessary for the elderly and disabled people with inconvenient legs and feet to go upstairs every day. very difficult. [0004] In order to solve this problem, stair-climbing wheelchairs of many different structures have appeare...

AI Technical Summary

Problems solved by technology

[0007] Due to the different specifications of the stairs, the planetary wheel type is difficult to adapt to all kinds of stairs with different heights, and it climbs alternately during the climbing process, which inevitably produces fluctuations, which affects the stability and safety of the stairs

[0008] At present, there are few walking types in the market. Although they have stable climbing and flexible activities, due to the walking type, the mechanical mechanism and circuit control are relatively complicated and expensive, so it is difficult to promote
