Power generation knapsack

Abstract

The invention discloses a power generation knapsack. The power generation knapsack comprises a knapsack frame assembly, a plurality of elastic assemblies, a motion mechanism and a battery unit. The elastic assemblies are arranged on one side of the knapsack frame assembly. The motion mechanism is arranged on the elastic assemblies and moves up and down on the knapsack frame assembly through the elastic assemblies. The motion mechanism comprises a power generation box, a power generator and a battery unit. The power generation box comprises a transmission assembly and a mechanical energy storage device. The knapsack frame assembly is provided with a rack, the rack is connected with the transmission assembly, the transmission assembly is connected with the mechanical energy storage device, the mechanical energy storage device is connected with the gear end of the power generator through a transmission gear, and the power generator is further electrically connected with the battery unit.According to the power generation knapsack, in the upward and downward motion process of the motion mechanism, power generation can be achieved, and the power generation efficiency is improved by twotimes compared with existing devices.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a power generation schoolbag capable of collecting vibration energy of a human body. Background technique [0002] With the development of science and technology, human life is increasingly inseparable from various electronic devices. However, the use of electronic devices is inseparable from electric energy, especially when using electronic devices outdoors. Outdoor charging of electronic products has become a A burning problem. Existing portable power generation equipment has made great progress. Among them, the products that directly use the kinetic energy of the human body to generate electricity are the earliest human power generation equipment for human beings. However, such products rely solely on the movement of a single part of the human body to generate electricity, which consumes a lot of energy for the human body; The kinetic energy of the human bod...

Problems solved by technology

Among them, the products that directly use the kinetic energy of the human body to generate electricity are the earliest human power generation equipment for human beings. However, such products rely solely on the movement of a single part of the human body to generate electricity, which consumes a lot of energy for the human body; The kinetic energy of the human body is converted into electrical energy and stored for subsequent use. This power generation device can convert the excess kinetic energy of the human body during walking and other sports into electrical energy storage. However, this type of power generation device has low efficiency in converting kinetic energy into electrical energy. question

There is an existing power generation device that obtains electric energy by vibrating up and down, but there is a defect that the power generation and energy storage of the generator can only be realized in a process of rising or falling of the device, and the power generation efficiency is not high
