Wheelchair robot with crotch blocking limit functions on basis of air bag roll contraction and expansion for old people

Abstract

The invention discloses a wheelchair robot with crotch blocking limit functions on the basis of air bag roll contraction and expansion for old people. The wheelchair robot structurally comprises a crotch blocking limit cushion, a seat frame, two armrest plates, two speed limit regulation and control plates, universal wheels and a pedal. The crotch blocking limit cushion is arranged inside the front end of the seat frame, the two armrest plates are mounted on the left side and the right side of the seat frame, the rear ends of the armrest plates are connected with two sides of the rear of the seat frame by means of electric welding, and the two speed limit regulation and control plates are mounted on the left side and the right side of the seat frame. The wheelchair robot has the advantagesthat the wheelchair robot is provided with the crotch blocking limit cushion, crotch blocking effects of a limit air bag roll cam be realized when a wheelchair topples over or under bumpy conditions,accordingly, the problems that the hips of old people forwardly slide along cushion and the old people are in lying states can be solved, the spines of the old people can be effectively protected, the old people can be effectively prevented from slipping out from the wheelchair to fall off, and limit effects can be realized for the old people; the cushion can be continuously refrigerated by the aid of principles for converting evaporation hot air of polymer hydrogel into cold air, accordingly, heat can be prevented from being generated on contact surfaces of users and the cushion due to long-term contact, and the comfort can be effectively enhanced for the users.

Description

technical field [0001] The invention relates to the field of intelligent robots, more precisely, it is a wheelchair robot for the elderly that realizes crotch clamping and positioning based on the shrinking and expanding of the airbag. Background technique [0002] When the elderly are at a certain age, their legs and feet are more inconvenient, so they need to use wheelchair robots to assist them and reduce the physical exertion of users. Existing wheelchairs are usually equipped with belts to protect the elderly, but they still exist as follows shortcoming: [0003] 1. When encountering some uneven roads or downhill sections, the elderly’s buttocks will still slide forward along the cushion and lie in a paralyzed position. This posture will cause discomfort to the elderly and cause serious damage to the spine, even Breaking away from the belt directly slides out and falls from the cushion in a paralyzed state, causing injury to the elderly, and the safety performance need...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the existing technology, the purpose of the present invention is to provide a wheelchair robot for the elderly based on the shrinkage and expansion of the airbag to realize the crotch limit, so as to solve the problems of the existing technology when encountering some uneven roads or downhill sections. The buttocks of the elderly will still slide forward along the cushion and become paralyzed. This posture will cause the elderly to be uncomfortable and cause serious damage to the spine. They may even slide out of the cushion in a paralyzed state after detaching from the belt, which is harmful to the elderly. Injuries are caused, and the safety performance needs to be improved; and when the wheelchair is used in hot weather, the contact surface between the user and the wheelchair will produce sweat stains for a long time, prone to prickly heat, or need to stand frequently to evacuate, and the defect of poor use feeling
