A human foot linear electromagnetic mechanical energy generating device

Abstract

The invention discloses a linear electromagnetic human foot mechanical energy generating set. By adoption of the generating set, momentum in the horizontal direction, generated by motion of human feet, can be efficiently converted into mechanical energy. The linear electromagnetic human foot mechanical energy generating set is small in size and adapts to the sizes of shoe soles. A liner electromagnetic generator is adopted to acquire the mechanical energy of the human feet, and according to the characteristic that the human feet alternately step on the ground, the mechanical energy of the human feet can be acquired more efficiently.

Description

technical field [0001] The invention relates to the field of new energy technologies. Background technique [0002] With the rapid development of electronic information technology in recent years, the application of mobile electronic devices has become more and more extensive, while the traditional power supply equipment - battery, has developed slowly, which greatly limits the miniaturization design and service life of mobile electronic devices. Moreover, when the battery power is exhausted, improper disposal of the battery will also cause environmental pollution. On the other hand, the human body is a rich energy complex. The digestive system of the human body absorbs the chemical energy of food and consumes it in the form of heat or mechanical energy through the daily activities of the human body. The collection of human body heat energy will have a certain impact on human health. Therefore, it is of great significance to collect human body mechanical energy to power mob...

Problems solved by technology

The disadvantage of this power generation structure is that the rack is easy to wear, the structure is complex, and the weight is large; on the other hand, when the human body walks, the displacement of the foot vertical to the ground is small, the stroke of the rack is short, and the power generation efficiency is low.

Another example is Li Weijin and Zhang Peng in their patent "Power Generation Shoes" (CN2762591), which proposed a method of using piezoelectric materials to collect the energy of the human body stepping on the soles of the shoes to generate electricity. The disadvantage of this method is that the piezoelectric The strength of the material is poor, and due to its crystal structure, the current emitted is also small; on the other hand, piezoelectric materials require high-frequency pressure shocks to have high power output, and the frequency of human walking is low, so the power generation efficiency Low

The disadvantage of this power generation structure is that the structure of adjacent magnets facing each other with the same pole makes the structure of the magnet piston unstable, and the liquid in the liquid chamber has leakage problems. The arrangement of the magnets is not easy to achieve a flat design, and the power density is relatively low.
