Energy collection backpack based on composite friction nano-generator structure

Abstract

The invention relates to the field of energy collection and conversion, in particular to an energy collection backpack based on a composite friction nano-generator structure. The backpack comprises abackpack body, energy conversion units and backpack shoulder straps. The backpack is characterized in that the energy conversion units are symmetrically distributed in the backpack and located at thepositions making contact with the back of the human body, the upper ends of the energy conversion units are fixedly connected with the shoulder straps, and the lower ends of the energy conversion units are fixedly connected with the backpack body. The power generation backpack is ingenious and compact in overall structural design, light in weight, capable of bearing large load, safe, reliable andwide in application range; according to a composite friction power generation structure based on the triboelectrification and electrostatic induction effects, energy of various forms of movement is collected, mechanical energy of a human body is converted into electric energy, energy collection and storage are carried out, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of energy collection and conversion, in particular to an energy collection backpack based on a composite friction nanogenerator structure. Background technique [0002] As a common item in daily life, backpacks are widely used because of their convenience and practicality in carrying items. In the process of carrying a load, the backpack will move with the movement of the center of gravity of the human body. This movement can be intuitively decomposed into two directions: in the vertical direction, due to the up and down movement of the center of gravity, the backpack will also have a relative lag. The up and down movement of the backpack is directly reflected in the pulling of the shoulder straps; in the horizontal direction, due to the forward and backward movement of the human body, the backpack will also have a relatively lagging forward and backward movement, which is directly expressed as the extrusion of the ba...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of the backpack is that the backpack adopts a complex mechanical structure, which is inconvenient to carry on the back due to its large size, and the resulting weight will definitely affect the use of the backpack; in addition, the main structural design purpose of the backpack is to reduce weight. , for energy harvesting, only the energy collected when the backpack moves up and down when a person is carrying a backpack is considered, and the energy harvesting in the horizontal direction is not considered
