Load-bearing power-assisted exoskeleton with damping function

Abstract

The invention discloses a load-bearing power-assisted exoskeleton with a damping function. The load-bearing power-assisted exoskeleton comprises a hip joint mechanism, a knee joint mechanism, an ankle joint mechanism and a waist space connecting rod supporting mechanism. The waist space connecting rod supporting mechanism comprises a rotary connecting piece and supporting assemblies symmetrically arranged on the two axial sides of the rotary connecting piece, and the ends, close to the rotary connecting piece, of the supporting assemblies are rotationally connected to the rotary connecting piece through first longitudinal rotating pieces. The supporting assemblies can rotate around the rotary connecting piece to be matched with a waist and a hip of a human body in size, the other ends of the supporting assemblies are connected with the hip joint mechanism, a length-adjustable pull wire and a supporting spring are axially arranged between the two supporting assemblies, and the two axial ends of the supporting spring are connected with the supporting assemblies on the corresponding sides through the pull wire separately. According to the load-bearing power-assisted exoskeleton with the damping function, the acting force generated by the vertical reciprocating motion of a heavy object in the motion process can be buffered, so that the muscle fatigue of the human body is reduced, the weight bearing capacity is improved, and meanwhile, the wearing comfort of a wearer can be improved.

Description

technical field [0001] The invention relates to the technical field of exoskeleton, in particular to a load-assisted exoskeleton with a shock-absorbing function. Background technique [0002] When people carry heavy objects, the lower limbs and spine will be under great pressure, and the limit of carrying heavy objects is small. Especially in areas with rough roads, vehicles cannot pass through these places, and people can only carry heavy objects on their backs, and the walking distance is relatively long. Naturally, a device that can reduce the pressure on the human body and increase the weight on the back is needed. [0003] Due to the complex structure of the human body, the movement of a single leg during human walking is usually divided into a swing phase and a support phase. The movement state of the body is constantly changing between the support phase and the swing phase. [0004] The weight-bearing exoskeleton is a device that can be worn on the human body and ca...

AI Technical Summary

Problems solved by technology

However, the above-mentioned weight-bearing walking assisting exoskeleton will have the following problems when actually carrying a heavy object on its back: 1. The heavy object is placed on the shelf. When the human body walks, the human body will reciprocate in the vertical direction, and the heavy object will Following the reciprocating movement of the human body in the vertical direction, the vertical reciprocating movement of the heavy object will increase the force on the human body, especially the waist, during each reciprocating movement, which will increase the fatigue of the human muscles and reduce the load-bearing capacity

2. The size of the hip component is fixed and cannot be adjusted according to the situation of different users, which will reduce the wearing comfort of the wearer
