A walking companion robot

Abstract

The invention discloses a walking assistance robot for the elderly, which includes a walking driving mechanism, a double herringbone pose transformation mechanism, a power-assisted anti-drop mechanism, a seat driving mechanism, a universal wheel fixed-axis mechanism, etc., and mainly realizes wheelchair transportation, power-assisted walking, Three functions of anti-drop protection. Its characteristics are: when the main electric push rod shrinks, the posture of the device rises, and it is in the power-assisted walking position. The device senses the user's motion intention through the human-computer interaction interface to realize adaptive and soft walking, and supports the user through the handrail. ; When the main electric push rod is stretched out, the posture of the device is lowered, and the seat is automatically stretched out under the drive of the motor, and is in the wheelchair conveying station, and the device is driven and controlled through the human-computer interaction interface; Surrounding and split structure design can effectively support the elderly and prevent them from falling forward, backward, left, and right.

Description

technical field [0001] The invention relates to intelligent robot technology, in particular to a multifunctional robot device serving the elderly. Background technique [0002] With the continuous development of population aging, the proportion of the elderly population in my country's total population is increasing. Authoritative statistics show that there are 169 million elderly people in my country. By 2030, the number of elderly people will rise to 400 million. The proportion will rise to 26 percent from the current 14 percent. Most of the older elderly often need special care and care, which requires high costs and manpower expenditure on the one hand, and greatly reduces the quality of life of the elderly on the other hand. The existence of a large number of elderly people with all kinds of disabilities has made the problem of helping their wives walk has become an urgent social problem to be solved, and the quality of life of the elderly has attracted more and more at...

AI Technical Summary

Problems solved by technology

Among them, the first is an armrest-assisted mobile robot, which is similar to an intelligent crutch, with a single structure and function, without considering the characteristics of the elderly who are prone to fatigue, and only has the function of assisting walking without wheelchair transportation; The skeletal power-assisted walker robot is more suitable for people with lower limb disabilities, but for most elderly people, it is inconvenient to wear, and the structure is complicated and bulky and not friendly enough; the main body of the third type is in the form of a four-wheeled wheelchair, and they all have Wheelchair transportation and a certain ability to assist in walking, but the structure is bulky and complicated, and the transition between the functions of walking assistance and transportation is not natural. The assisting effect of the two walking assistance states is poor, and there is less consideration for the safety of users.
