Problems solved by technology

With the improvement of residents' living standards, people have put forward higher requirements for product quality, performance and comfort. Coupled with the accelerated pace of urban life, children spend less and less time at home to take care of the elderly and patients. It is inconvenient for people to use manual wheelchairs, so they cannot get good care. How to solve this problem has become a topic of increasing concern to the society
[0003] The emergence of electric wheelchairs enables the elderly and disabled friends to no longer rely on the help of others. They can travel alone by operating electric wheelchairs, making their life and work easier and more convenient. Traditional electric wheelchairs are based on manual wheelchairs. Basically, superimposed power drive device, controller, battery and other components, transformed and upgraded, manual manipulation of the controller can drive the wheelchair to complete various actions such as forward, backward, and steering, but the electric wheelchair improved from the manual wheelchair Wheelchairs still have many deficiencies in terms of support structure strength, ride comfort, center of gravity configuration, humanized operation, etc.
