Problems solved by technology

The position of the electric wheelchair with this structure cannot be changed once the pair of armrests are assembled, that is, they always correspond to the two sides of the vehicle body in a parallel state, so there is confusion in the actual use process, because Many disabled people, especially those with high paraplegia, usually find it difficult to get on the front of the car. They are often carried by the escort to the chair of the electric wheelchair. The edge of the bed where the patient lies, that is, the front of the chair of the electric wheelchair is docked with the edge of the bed, and the patient moves from the bed to the edge of the chair.

However, since the front of the chair is aligned with the edge of the bed, the stability of the electric wheelchair cannot be guaranteed, because when the patient is in contact with the chair, the center of gravity is not located at the center of the chair, but at the edge of the front of the chair, so the electric wheelchair The wheelchair may overturn forward, causing the patient to fall to the ground, and even cause a fall accident

In addition, even if the caregiver carries the patient to the chair, it is more laborious because of the need to sit in the front
