Electric wheelchairs are battery-powered auxiliary mobility tools that replace manual pushing with electric drive, which is a revolutionary upgrade from traditional manual wheelchairs. Manual wheelchairs require users to continuously push the wheels with their arms to move forward. For the elderly with aging muscles and degraded joint flexibility, as well as disabled people with limited upper limb function, long-term manual pushing will cause severe fatigue, arm soreness, wrist strain and even chronic joint diseases, which easily cause secondary damage to the body. In contrast, electric wheelchairs rely on motor drive to complete all walking actions. Users only need to lightly operate the control lever to achieve forward, backward, turning and stopping. No physical strength is required during the whole driving process. Even after long hours of outdoor travel and long-distance movement, users will not feel physical tiredness. It effectively protects the upper limb joints and muscle health of the elderly and disabled users, avoiding physical strain caused by daily mobility activities.
