Intelligent electrically-powered wheelchair

Abstract

The invention discloses an intelligent electrically-powered wheelchair which is easy to install, simple to control, convenient to operate, and high in stability and practicability. The intelligent electrically-powered wheelchair comprises a mechanical part, a control part and a lithium batter powering part, and is structurally characterized in that the mechanical part is a wheelchair body, and the control part is formed by an upper computer and a lower computer combined together; the upper computer comprises a first ARM core processor, and a speed display module, an electric quantity display module, an acceleration reading module, a Hall shifter control module, a reversing module and a braking module connected with the first ARM core processor; the lower computer comprises a second ARM core processor, a position detection circuit, a power drive circuit and a protection circuit connected with the second ARM core processor, and an inverter circuit connected with the power drive circuit which is simultaneously connected with the position detection circuit and the protection circuit respectively; and the upper computer and the lower computer communicate with each other in a serial port communication manner.

Description

technical field [0001] The invention belongs to the technical field of electric wheelchairs, in particular to an intelligent electric wheelchair. Background technique [0002] With the improvement of living standards, people pay more and more attention to the elderly and the disabled, and more and more electric wheelchairs come into the sight of consumers. However, because most electric wheelchairs have two extremes, most imported wheelchairs have relatively high The performance is good but the price is expensive, which is beyond the consumption capacity of ordinary people. The more common electric wheelchairs in China consume a lot of power and have poor battery life. Therefore, most of the wheelchairs used in households or hospitals are still traditional hand-cranked wheelchairs. Moreover, most of the current motor drives adopt the control method of position sensor, the control mode is single, the stability is limited, and the reliability and safety are low for people with...

[0002] With the improvement of living standards, people pay more and more attention to the elderly and the disabled, and more and more electric wheelchairs come into the sight of consumers. However, because most electric wheelchairs have two extremes, most imported wheelchairs have relatively high Good performance but expensive price, which exceeds the consumption capacity of ordinary people, and the more common electric wheelchairs in China have high power consumption and poor battery life, so most of the wheelchairs used in households or hospitals are still traditional hand-operated wheelchairs

Moreover, most of the current motor drives adopt the control method of position sensor, the control mode is single, the stability is limited, and the reliability and safety are low for people with limited mobility. Therefore, it is difficult to provide convenience and safety for the elderly and the disabled in practical applications. , free travel
