Self-balancing electric wheelchair

Abstract

The invention relates to a self-balancing electric wheelchair. The technical scheme is that the self-balancing electric wheelchair comprises a base, a rotating lifting platform and a supporting and conveying platform arranged from bottom to top, wherein the base comprises a walking mechanism for adjusting the position of the base; the rotating lifting platform comprises a lifting mechanism for adjusting the height position in the vertical direction and a rotating mechanism for adjusting the angle in a horizontal plane; and the supporting and conveying platform includes a supporting mechanism for supporting a human body and a conveying mechanism for pushing out or retracting the supporting mechanism toward one side. when the conveying mechanism stretches and center of gravity is shifted during the transfer process from the wheelchair to a bed, transverse balance of the wheelchair is dynamically adjusted, and wheelchair rollover is prevented; the human body is conveyed to the bed surfacethrough the conveying mechanism and a sending mechanism, the function of automatically getting on and off the bed is better realized; and the self-balancing electric wheelchair is flexible and convenient to use.

Description

technical field [0001] The invention relates to a power wheelchair, in particular to a self-balancing multifunctional electric wheelchair which can automatically send a user on and off the bed. Background technique [0002] my country is a country with a large population and the most populous country in the world. The aging population is also increasing. In order to help the elderly to live independently and achieve independent living and other actions, so as to reduce the burden on their children, the demand for wheelchairs is also increasing. As the total demand for wheelchairs in society increases, the entire wheelchair industry is facing huge challenges, and there are also severe challenges for its functionality. Wheelchairs with a single function can no longer meet the needs of users, so it is of great significance to design a multifunctional, economical and safe electric wheelchair to assist the disabled. In recent years, many companies, universities and research insti...

However, the function of this mechanism is single, it can only lift people to a certain height, and can only meet some behaviors that require a high level

[0004] On the basis of the Chinese patent document (application number 201120429383.6), the Chinese patent document (application number 201420470513.4) relates to an electric wheelchair that can go to bed. While sending someone to bed, the two movements cannot be performed independently, and this movement can only be performed on a fixed form of bed

Neither of the above two patents can achieve 360° free rotation of the seat. The first patent can only realize lifting and lowering. Although the second patent can assist in bed, the telescopic and lifting can only be performed simultaneously, which has limitations.

Therefore, some basic needs of the elderly cannot be met.

[0005] To sum up, both of the above two have corresponding functional deficiencies. More importantly, the center of gravity of the wheelchair changes during the process of going to bed, and it is very easy to tip over. Therefore, the current wheelchair has a single function and better satisfaction. In the urgent need of the disabled in the current society, it is imperative to design a safe and reliable electric wheelchair that can be lifted, 360° free rotation, and better automatic bed and get off functions.
