Abstract

The invention relates to an auxiliary chair, in particular to a gravity center adaptive auxiliary chair, and aims to solve the problems of difficulty in standing, obstacle crossing in walking, inconvenience in picking articles and the like for old people or disabled people. The gravity center adaptive auxiliary chair comprises a seat module, a leg module, a chassis module, a rocker arm module andtwo planet wheel modules, wherein the seat module is installed on the leg module, the leg module is installed on the chassis module, the rocker arm module is installed on the chassis module and located in front of the leg module, and the two planet wheel modules are installed on two sides of the chassis module respectively. The gravity center adaptive auxiliary chair is designed for the problems of standing, obstacle crossing in walking, auxiliary picking and the like of old people, assists in life of old people and disabled people, and assists in life of users to a certain extent, wherein assistance includes but not limited to auxiliary standing, auxiliary walking, auxiliary picking and the like.

Description

technical field [0001] The invention relates to an auxiliary chair, in particular to an auxiliary chair adapted to the center of gravity, and belongs to the technical field of auxiliary chairs. Background technique [0002] At present, the aging trend of the population is serious. With the growth of age, it is inevitable that there will be barriers to mobility. The lack of independent mobility of the elderly is a major problem today. Improving the quality of life of the elderly has become a major demand of the society. [0003] At present, the wheelchairs on the market that can realize the transformation of sitting and standing mainly adopt the linkage mechanism to realize the posture transformation, and the chassis prevents it from falling over due to the forward movement of the center of gravity after standing through the auxiliary wheels. However, this design does not fundamentally solve the problem of shifting the center of gravity during the standing process. At the sa...
