Propulsion assist device for manual wheelchair applying mechanical self-energizing effect

摘要

Disclosed is a mobility assistance device connected to a manual wheelchair to provide driving force. The movement assistance device provides sufficient driving force and braking force while using the motor by using the magnetic reinforcement effect. Mobility aids can be easily connected to manual wheelchairs without the need for bending. The self-reinforcing effect is provided in a mechanical manner, and the device has a simple structure, so there is little risk of failure. Mobility aids are economically priced, enabling the elderly and the disabled to improve their self-esteem as members of society and engage in safer and more active social activities.
