Description
Technical Field
The utility model belongs to the field of shoes, relates to the field of electromagnetic energy collecting devices in intelligent wearing, and particularly relates to a device for collecting energy by squeezing soles by human walking in the soles.
Background
The human body walks every day, and the human body performs self-movement by using self-biological energy. The walking amount of healthy people is at least 4000 steps per day, the activity amount is the basic exercise amount of people, and the standard is improved to 7000 steps in order to achieve the effect of promoting health and preventing various chronic diseases.
When a person walks, the ground and the foot squeeze the sole when the shoe lands; when the shoe is lifted off the ground, the squeezing disappears. Therefore, taking a certain measure, collecting the mechanical energy of the periodical extrusion process, converting the mechanical energy into electric energy to supply power for a plurality of wireless sensor nodes and the like becomes an focus of research and utility model. For example, a domestic and well-known brand of Li Ning is sold for a plurality of sports shoes with so-called chips arranged on soles, an embedded system integrating a sports sensor is adopted, data such as speed and acceleration of an athlete in the running process are specially collected, and the data are wirelessly transmitted to analysis software on a mobile phone to help the athlete analyze existing sports technical problems, so that the aim of improving the performance is fulfilled. Unfortunately, the power supply is battery-powered, has life limitations, and can be chemically contaminated after disposal. If the mechanical energy of the sole extrusion process can be utilized to provide electric energy, the method is very beneficial to the popularization of environmental protection and chip shoes.
Energy harvesting by heel squeezing soles is seen at the earliest J.Kymissis, C.Kendall, J.Paradiso and N.Gershenfeld.Parasitic power harvesting in shoes, inProc.of the Second IEEE International Conference on Wearable Computing (ISWC), IEEE Computer Society Press, pages pp.132-139, october 1998; recently, the utility model patent with the Chinese application number 201610372111.4 is named as a multifunctional power generation shoe and the utility model patent with the Chinese application number 201620404994.8 is named as a shoe with the pressure accumulation and charging functions. The above 3 documents all adopt the sole to exert pressure on the piezoelectric ceramic plate to collect energy, the piezoelectric mode is simpler in technology for converting mechanical energy into electric energy, but the piezoelectric device is generally suitable for collecting high-frequency vibration energy above 50Hz, and the low frequency of 1-2Hz is often too low in generated charge amount as walking, unlike an electromagnetic energy collecting device.
The utility model patent of China application number 201520569683.2 is named as a walking power generation shoe, the utility model patent of China application number 201610029877.2 is named as a sports power generation sole, the two patents adopt the expansion and contraction of an air bag to generate power, when a person lifts the foot, air enters the air bag of the sole from the atmosphere, when the foot is put down, the air bag is isolated from the atmosphere and is discharged from the other outlet, and the mechanical energy of the air movement in the air bag is converted into electric energy through an electromagnetic device. The utility model patent with the Chinese application number of 20162000277.4 is named as a plate spring compression power generation shoe, and the position of a coil is changed by utilizing the expansion and contraction of a spring during walking, so that the purpose of generating power by cutting a magnetic induction wire by the coil is achieved. The common disadvantages of analyzing the above 3 devices are: firstly, a closed magnetic circuit is not formed, and magnetic leakage is large, so that the energy conversion efficiency is low; secondly, there are all movable parts, which is unreasonable for shoes working in severe environments, and accidents such as jamming are easy to occur. For two devices adopting the air bag, foreign matters are easy to be sucked or water inflow accidents occur due to gas exchange with the atmosphere; meanwhile, a valve-like structure exists in the device, so that the device is easy to break down and fragile in a severe working environment. The plate spring compression power generation shoe device is provided with not only movable parts in the vertical direction, but also large stroke, and is difficult to install on the sole.
