A piezoelectric self-powered positioning shoe

Abstract

The invention discloses a piezoelectric self-power-supply positioning shoe. The piezoelectric self-power-supply positioning shoe comprises a sole and a vamp, wherein a power module, a control module, a GPS positioning module and a wireless communication module are arranged in the sole. The power module comprises a piezoelectric power generation unit and an energy storage unit. A compressive deformation region is arranged on the sole. The piezoelectric power generation unit comprises a press block and a piezoelectric body, wherein the press block makes contact with the compressive deformation region and is matched with the compressive deformation region, the piezoelectric body is driven by the press block to deform so as to generate electricity, and the piezoelectric body is fixedly arranged in the sole and connected with a circuit of the energy storage unit. Under the action of gravity of a human body, the compressive deformation region deforms, the press block which makes contact with the compressive deformation region drives the piezoelectric body to deform due to the fact that the press block relatively shifts, different electric charges are generated by the piezoelectric body in the deformation process, the electric potential difference is formed, and therefore in the process that a wearer walks, the piezoelectric body continues generating electricity, electric energy is stored in the energy storage unit, the control module, the GPS positioning module and the wireless communication module can be continuously driven to work without restriction of the time and natural conditions, and positioning information of the wearer is provided for the outside world.

Description

technical field [0001] The invention relates to a positioning shoe, in particular to a piezoelectric self-powered positioning shoe. Background technique [0002] In recent years, incidents of children, the elderly, and college students losing contact have occurred from time to time. How to locate the lost contact in time and how to send a request signal in time in case of an emergency is an urgent problem to be solved. Wearable positioning devices are a better solution. At present, products such as positioning watches, positioning shoes, and positioning schoolbags can be seen in the market. [0003] However, most of these products are powered by batteries or external chargers, and the battery life is insufficient. Outdoor explorers fall behind or encounter accidents, the elderly or children get lost or encounter danger, undercover police encounter danger, important people or In many situations such as high-income people being kidnapped, once the power of the positioning dev...

Problems solved by technology

[0008] The disadvantage of the GPS positioning shoes is that after the piezoelectric rubber is stepped on, it is reset solely by the elastic force of the piezoelectric rubber itself. Affected by people’s walking steps, the piezoelectric rubber has not returned to its original position before the next step on the pressure, resulting in The deformation space of each deformation of piezoelectric rubber is limited, and the power generation efficiency is low
