Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of wheelchair, specifically relates to a wheelchair convenient to care. BACKGROUND

[0002] At present on the market, the design of electric wheelchair mainly focuses on enabling the old or the patient to use independently, assisting the movement of the user through the electric drive system, thereby improving their self-care ability. However, this design often ignores the needs of the caregiver in the care process. In practical application, when assisting the old or the patient, the caregiver usually needs to push the electric wheelchair like using the traditional manual wheelchair, which not only cannot fully utilize the electric drive advantage of the electric wheelchair, but also increases the physical burden of the caregiver.

[0003] In addition, in order to ensure the stability of the electric wheelchair, the existing electric wheelchair adopts the design of four-wheel landing. Although this design improves the stability of the wheelchair to a certain extent, it is very inconvenient when the caregiver pushes the wheelchair to turn. The structure of four-wheel landing limits the turning flexibility of the wheelchair, making it difficult for the caregiver to operate in a narrow space or when the direction needs to be quickly adjusted.
