Climbing method of electric wheelchair based on center of gravity measurement and control and its electric wheelchair

Abstract

The invention provides a stair climbing method for an electric wheelchair based on gravity center measurement and control. The method is applicable to the technical field of wheelchairs and is characterized in that the electric wheelchair comprises a track and a rear wheel, wherein a motor is disposed at a joint pivot of the track, and the motor divides the track into a first track section and a second track section; the track propels the wheelchair to go downstairs, and a first distance between the tail end of the track and a horizontal plane of stairs is detected; the track is bent, and the posture and the gravity center of the electric wheelchair are adjusted; if the first distance exceeds a first threshold value, the gravity center will fall onto a slope of the stairs, and then the track is straightened and gradually releases the electric wheelchair to move down; and if the first distance is equal to the first threshold value, the gravity center will fall onto a horizontal plane of the stairs, and adjustment of the posture and the gravity center of the electric wheelchair will be continued. The invention also provides the electric wheelchair. In this way, the method and the wheelchair provided by the invention have the advantage that bumping of the stair climbing wheelchair taking place during stair climbing can be avoided through improvement of the track structure and stair climbing control.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a method for climbing stairs of an electric wheelchair based on center of gravity measurement and control and the electric wheelchair. Background technique [0002] Most of the existing wheelchair user groups are the elderly, the disabled, people with inconvenient mobility or physically impaired people. At the same time, it is difficult for these people to control the electric wheelchair accurately, correctly, flexibly and freely, and they must be accompanied by others. The operation of such personnel is relatively difficult, and the wheelchair cannot be made more convenient, intelligent, simple, and humanized, and it also has defects in autonomous or assisted control operations by others. [0003] In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it. Contents of the invention [0004] In view of th...

Problems solved by technology

[0002] Most of the existing wheelchair user groups are the elderly, the disabled, people with inconvenient mobility, or people with impaired limbs. At the same time, it is difficult for these people to control the electric wheelchair accurately, correctly, flexibly, and freely, and they must be accompanied by others.

The operation of such personnel is relatively difficult, and the wheelchair cannot be made more convenient, intelligent, simple, and humanized, and there are also defects in the control operation independently or assisted by others

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
