With the aging of the global population, especially the social problem of inconvenient life for the elderly with weak lower limbs, we have designed an easy-to-control intelligent wheelchair for the elderly to get up, stand, go to the toilet and travel. The mechanical structure of the wheelchair is cushion lifting part, cushion opening and closing part, pedal lifting part and other auxiliary parts. The control system is divided into main controller, power conversion module, motor drive module, GSM network module, satellite positioning module, wireless communication module, camera and display system, etc. Among them, the electric push rod is used to drive the linkage mechanism to realize the lifting of the seat cushion, the DC motor drives the rack and pinion mechanism to realize the opening and closing of the seat cushion, and the micro push rod is used to realize the lifting of the pedal. Through the rear camera and the front display screen, the rear view is observed, and the remote positioning and one-key alarm functions are added. The family can check the position and condition of the elderly in real time on the APP page, and has the functions of Bluetooth anti-losing, and reminding to take medicine. The wheelchair is easy to operate, safe and reliable and easy to maintain. It is not only suitable for the elderly living alone with lower limb weakness, but also for nursing homes, barrier-free toilets and other occasions.
