Embodiment Construction

[0009] Piezoelectric materials can generate voltage when they are deformed by external forces. Based on this principle, piezoelectric power generation shoes that use the impact force naturally generated when people walk are designed to generate electricity. When a person walks, when the foot hits the ground, as if attached Figure 5 As shown, the pedal 6 is subjected to a downward force, and the cushion 7 can ensure the comfort of the feet. The force receiving body 4 and the force transmitting body 5 convert this force into a horizontal force and act on the piezoelectric crystals 3 on both sides of the groove box 2, Make it weakly deformed, and the electrode b of the piezoelectric crystal 3 generates a momentary high voltage; Image 6 As shown, the force acting on the piezoelectric crystal 3 disappears, the deformation of the piezoelectric crystal 3 recovers, and the electrode c of the piezoelectric crystal 3 generates an instantaneous high voltage. The electrodes of the two ...

Abstract

The invention pertains to the field of living goods, which particularly relates to an electric shoe driven by a piezocrystal. The shoe can power supply or charge for portable electrical apparatuses at any time. The shoe which can generate electricity consists of a sole and an upper and is characterized in that a generating device is arranged at the inside part of the heel of the sole; the outside of the shoe is provided with an accumulator; the generating device consists of a pedal, a stressing body, a dowel block, a piezocrystal, a slot-type box and a socket. The accumulator consists of a plug and an electric storage apparatus. The generating device is connected with the electric storage apparatus by the socket and the plug. The inside of the heel is provided with a rectangular groove; the external side of the rectangular groove is provided with a lead wire groove; the external side of the heel is provided with a round hole for arranging the socket; the upper part of the heel is provided with a pedal slot for preventing the horizontal movement of the pedal. The shoe which can generate electricity has simple and compact structure, hardly being damaged, high efficiency of generating electricity and comfortable wearing and can power supply or charge portable electric apparatuses such as mobile phone and mp3 at any time, thus bringing great convenience to the life and traveling of people.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to power generation shoes using piezoelectric crystals to generate power for portable electrical appliances at any time. Background technique [0002] At present, there are several patented technologies for power generation shoes in China, most of which use magnetic power generation. For example, the patented power generation shoes (patent number: 200520105738.0) are equipped with a power generation module and a generator inside the sole. Through the natural stepping action when walking, the rack in the power generation module drives the meshing gears, and another gear drives the generator. generate electricity. This kind of power generation shoes generally have complex mechanisms, high cost, and are prone to problems, and the soles are greatly deformed, making them uncomfortable when walking, so they have not been widely used. Contents of the invention [0003] The ...
