The invention discloses a walking energy collection system, which comprises a piezoelectric power generation device and an electric energy collection device connected with the piezoelectric power generation device. The piezoelectric power generation device comprises a pressure bearing component, a support component, a two-stage pressure amplification component, an elastic component and a piezoelectric component, wherein the pressure bearing component bears walking pressure; the support component supports the pressure bearing component; the two-stage pressure amplification component adopts a wedge block, and amplifies pressure in a combined way; the elastic component resets the pressure amplification component and the pressure bearing component; and the piezoelectric component converts mechanical energy into electric energy. The electric energy collection device comprises a rectification circuit, an energy storage capacitor, a control circuit and a voltage stabilizing circuit, which are sequentially cascaded. According to the walking energy collection system, the mechanical energy in a walking process is converted into the electric energy which is easily collected and utilized, so that the collection efficiency of the electric energy collection device is improved; the walking energy collection system is suitable for the low-frequency excitation of walking; and fatigue wear to the components in the system at work can be effectively reduced.

Description

technical field [0001] The invention relates to an energy collection system, in particular to a walking energy collection system. Background technique [0002] With the gradual depletion of traditional energy, people pay more and more attention to new, sustainable and clean energy. Clean energy includes hydrogen energy, nuclear energy and renewable energy. Renewable energy refers to energy that can be regenerated from raw materials, such as wind power, solar energy, biomass, ocean tide energy, etc. Renewable energy does not have the possibility of energy depletion, so it is increasingly valued by many countries, so energy collection has become a widespread method of developing new energy sources. At present, energy collection is mainly based on the collection and utilization of natural energy such as solar energy and wind energy. However, natural energy such as solar energy and wind energy is limited by natural conditions and cannot provide energy stably. In fact, there a...
