Quasi-zero-stiffness human motion energy collecting backpack

Abstract

The invention relates to a quasi-zero-stiffness human body motion energy collecting backpack which comprises a quasi-zero-stiffness human body motion energy collector; the quasi-zero-stiffness human body motion energy collector is connected with a load-bearing backpack through an installation protruding block on a connecting sliding block rack. The quasi-zero-stiffness human body motion energy collector comprises a shell, a front cover plate, a quasi-zero-stiffness assembly, a transmission assembly, a mounting plate, a pawl disc assembly, a magnet disc assembly, a main shaft, a coil and a rear plate; the quasi-zero-stiffness assembly is connected with the shell; the transmission assembly is mounted on the mounting plate and connected with the quasi-zero-stiffness assembly in an engaged mode; the pawl disc assembly is installed on the other face of the mounting plate and connected with the magnet disc assembly in a meshed mode; the magnet disc assembly is installed on the main shaft through a bearing and corresponds to the coil, and the coil is embedded in the rear plate in a circumferential array mode. Compared with the prior art, the backpack can continuously output electric energy with a high energy utilization rate and conversion rate, and avoids defects that an existing power generation backpack is low in output power, low in energy conversion efficiency and the like.

Description

[technical field] [0001] The invention relates to the technical field of human body energy collection, in particular to a quasi-zero-rigidity human body movement energy collection backpack. [Background technique] [0002] The use of portable and wearable electronics has grown steadily in recent decades. While the performance of these electronic devices is improving, the power required is also getting higher and higher. How to continuously supply power to these portable electronic devices has become a difficult problem. The traditional battery power supply has the disadvantages of limited power supply time and environmental pollution caused by discarded batteries. In order to overcome the disadvantages of battery power supply and prolong the use time of portable and wearable electronic products, researchers have begun to study ways to recover energy from the environment and human motion to generate electricity. [0003] The human body dissipates a lot of energy in daily lif...
