Load-adjustable suspension backpack device

Abstract

A load-adjustable suspension backpack device comprises an adjusting mechanism and two sets of constant force mechanisms, the adjusting mechanism and the two sets of constant force mechanisms are arranged on the other side face of a back plate, and the two sets of constant force mechanisms are symmetrically arranged relative to the adjusting mechanism. The adjusting mechanism comprises a guide raillead screw, a sliding block and a first guide wheel set. Each set of constant force mechanism comprises a first spring, a second guide wheel set, a swing rod and a flexible rope. One end of the firstspring is mounted at the bottom of the back plate; the second guide wheel set is rotatably mounted at the upper part of the back plate; one end of the swing rod is rotationally installed on the backplate, the other end of the swing rod is arranged in a sliding groove of a transverse frame on the back plate and can slide, one end of the flexible rope is fixed to the other end of the first spring,the flexible rope is wound around guide wheels of the second guide wheel set and the first guide wheel set, and the other end of the flexible rope is fixed to the other end of the rocker. The whole backpack device is of a passive structure, movement of a human body under various frequencies is met, it can be guaranteed that the backpack is static relative to the ground, and the requirements of different loads can be met.

Description

technical field [0001] The invention relates to a suspended backpack device, in particular to a suspended backpack device with adjustable load. Background technique [0002] With the continuous improvement of people's living standards and the continuous development of science and technology, people have more requirements for the comfort and safety of wearable devices. As a common wearable device, backpacks serve all aspects of human beings. There are family backpacks for civilian use and special backpacks for military use. No matter what kind of backpack is loaded with a heavy load, because the center of gravity of the human body moves up and down when walking or running, the backpack cannot fit the human body very well, resulting in relative motion. The inertial impact generated by this relative movement causes additional energy consumption to the human body itself.

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a suspension backpack device with adjustable load to overcome the problem of the inertial impact of the backpack on the human body due to the up and down movement of the center of gravity when the human body is moving when the human body is walking or running with a backpack on its back
