An intelligent control device and method for a structurally adjustable wheelchair

Abstract

The invention provides an intelligent regulating and control device of a structurally adjustable wheelchair. The intelligent regulating and control device comprises a wheelchair main body, a wheelchair control mechanism and a data acquisition unit, wherein the data acquisition unit comprises a human state information acquisition module, a wheelchair state information acquisition module and a command input module; the wheelchair main body comprises a wheelchair support frame, a wheelchair seat plate, a wheelchair backrest which is connected to the wheelchair seat plate in a swinging mode and wheelchair supporting legs which are connected to the sides of the wheelchair support frame in a swinging mode; the wheelchair control mechanism comprises a controller and an executing mechanism; the controller is capable of outputting control commands in accordance with signals acquired by virtue of the data acquisition unit; and the executing mechanism includes a first executing mechanism which is used for controlling the wheelchair backrest to swing by 90-180 degrees relative to the wheelchair seat plate and a second executing mechanism which is used for controlling the wheelchair supporting legs to swing by 90-180 degrees relative to the wheelchair seat plate. According to the intelligent regulating and control device provided by the invention, a wheelchair state is regulated by acquiring a human state and the wheelchair state, so that comfort of a wheelchair user in a sitting posture is enhanced and dependency on nursing personnel is reduced; and a purpose of assisting the wheelchair user in movement is achieved.

Description

technical field [0001] The invention belongs to the field of intelligent wheelchairs, and in particular relates to an intelligent control device and method for a structurally adjustable wheelchair. Background technique [0002] With the rapid progress of the aging process, the concern for the elderly and the disabled is getting more and more attention from the society and the government. As the children of office workers, there is very little time for the elderly; or due to economic conditions, the number of social workers is generally insufficient, which makes it impossible to keep up with the personalized service needs of the elderly and the disabled. At present, wheelchairs cannot provide real-time intelligent control services according to people's needs. [0003] For people with disabilities and the elderly who need to rely on wheelchairs for a long time, ordinary wheelchairs can meet the travel needs of most people, but sitting in wheelchairs for a long time is likely ...

AI Technical Summary

Problems solved by technology

Although it can meet the daily travel needs of some people who cannot operate wheelchairs by hand, it cannot solve the harm caused by sedentary sitting, and is not conducive to the rehabilitation of people with disabilities.

The wheelchairs designed in some patents can adjust the telescopic frame and other mechanisms to realize the lying of the wheelchair and assist the user to stand up, but basically all adjustments are manual, and the wheelchair structure cannot be adjusted independently to achieve the purpose of actively and intelligently assisting the rehabilitation of wheelchair users

In addition, there are many patents that design human body parameter collection devices for monitoring the physiological information of wheelchair users. Although this solution can monitor the physiological information of users, it can provide early warnings for abnormal information and remind wheelchair users to improve their sitting posture and increase Exercise, etc., but it still needs to be handled by the user himself, and it is quite difficult for patients who cannot exercise, so this kind of group also needs a caregiver to handle it, which will not only increase the burden on society and family, but also put a burden on such patients.
