AI Technical Summary

Technical Problem

Prolonged standing work easily leads to lower limb fatigue. Existing technologies cannot effectively solve this problem. The technical problem is how to address the issue of prolonged standing work. Existing technologies cannot provide a device that allows operators to sit in a near-standing posture at any time, leading to lower limb fatigue and occupational diseases.

Method used

An external assisted exoskeleton frame was designed, including a thigh bar, a knee joint structure, and a lower leg bar. The thigh bar and lower leg bar are connected by the knee joint structure. A seating support and binding are installed to achieve angular positioning and fixation of the thigh bar and lower leg bar. It is equipped with a locking and unlocking mechanism and an anti-slip limiting component, allowing adjustment of the angle of the thigh bar and lower leg bar to accommodate different user leg lengths.

Benefits of technology

It allows the operator to sit in a near-standing or semi-squatting posture at any time, reducing lower limb fatigue, and allows for natural walking while seated. It has a compact structure and is comfortable to wear.

Abstract

The utility model discloses an in-vitro auxiliary exoskeleton support which comprises thigh rods corresponding to thighs of a human body, knee joint structural parts corresponding to knee joints of the human body and shank rods corresponding to shanks of the human body. The thigh rod is connected with the shank rod through the knee joint structural part, the thigh rod and the shank rod are hinged to each other through the knee joint structural part and can be positioned and fixed at an angle, and a sitting supporting part corresponding to the buttocks of the human body and an upper binding part used for binding the thigh rod to the thighs of the human body are installed on the thigh rod. A supporting leg rod used for supporting the ground is installed at the lower end of the shank rod, and a lower binding piece used for binding the shank rod to the shank of the human body is further installed on the shank rod. The utility model has the advantages that the human body can sit in a posture close to standing at any time after wearing, so that the fatigue of the lower limbs of the human body during operation is relieved, and the human body can walk naturally after wearing without any inconvenience during walking.
