Medical obstacle avoidance wheelchair capable of being automatically controlled

Abstract

The invention provides a medical obstacle avoidance wheelchair capable of being automatically controlled, relates to the technical field of medical machinery, and aims at solving the problems that when an existing wheelchair is used, ventilation and heat dissipation cannot be conducted due to the fact that the back of a patient makes contact with a backrest of the wheelchair for a long time, and prickly heat is prone to growing on the back of the patient. The medical obstacle avoidance wheelchair comprises a main body, a vertical groove and a bottom groove, wherein an inner groove is formed inthe outer end of a transverse plate and is of a T-shaped structure; a carrier plate is arranged on the inner side of the bottom of the main body, and a servo motor is mounted at the top of the carrier plate; a rotating plate on the side surface of the carrier plate is mounted on the inner side of the bottom of the main body through a rotating shaft; the vertical groove is formed in the inner sideof a vertical plate and is of a rectangular structure; a sawtooth-shaped structure is arranged at the bottom of an ejector block, and the sawtooth-shaped structure at the bottom of the ejector blockis meshed with a gear on the outer side of a rotating piece; and the bottom groove is of a rectangular structure and is formed in the bottom of the side face of the main body. When the wheelchair is used, ventilation and heat dissipation can be conducted on the back of the patient through the vertical groove, and pedals can be adjusted through the bottom groove.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to an automatic controllable obstacle avoidance wheelchair for medical use. Background technique [0002] A wheelchair is a chair with wheels that can help replace walking. It is divided into electric and manual folding wheelchairs. It is an important mobile tool for home rehabilitation, turnover transportation, medical treatment, and outing activities for the wounded, sick, and disabled. Wheelchairs not only meet physical disabilities. More importantly, it is convenient for family members to move and take care of patients, so that patients can use wheelchairs to perform physical exercises and participate in social activities. [0003] For example, the application number: CN201410623732.6 relates to an intelligent wheelchair with strong load capacity, flexible movement, and functions of autonomous positioning, navigation, and obstacle avoidance, including a w...
