Embodiment
With reference to Fig. 1, the Portable power generation device that the present invention proposes by supporting seat 1, pendulum mound 2, rotating shaft 3, plectrum 4, piezo-electric generating structure 5, keep out seat 6 and wire 7 forms.The structural representation of pendulum mound 2 and plectrum 4 respectively as shown in Figures 2 and 3.Pendulum mound 2 has an aperture, be fixed on supporting seat 1 by rotating shaft 3 by pendulum mound 2, when the quadruped locomotion of whole Blast Furnace Top Gas Recovery Turbine Unit (TRT) with human body or animal, pendulum mound 2 can freely swing left and right.Open several slits at the bottom circular arc camber of pendulum mound 2, in each slit, insert a slice plectrum 4 respectively, by modes such as filling adhesives, plectrum 4 is fixed in pendulum mound 2.Piezo-electric generating structure 5 and keep out seat 6 is fixed on supporting seat 1 bottom by modes such as use binding agents.The schematic diagram of piezo-electric generating structure 5 as shown in Figure 4, is made up of thin sheets of piezoelectric material 8, sheet metal 9 and thin sheets of piezoelectric material 10, and thin sheets of piezoelectric material 8 and piezoelectric plectrum 10 are bonded on two surfaces of sheet metal 9 respectively by binding agent.Keep out seat 6 and adopt quadrant cylindricality or similar structures, as shown in Figure 5, when piezo-electric generating structure 5 is stirred by plectrum 4, bend along the circular arc camber of keeping out seat 6.
The shape of above-mentioned supporting seat 1 is not limited to rectangle, also can adopt other shapes.Plectrum 4 adopts hard metal or plastic production to form, the thickness of plectrum 4 to be set as that when stirring piezo-electric generating structure 5 plectrum 4 can not bend or fracture required thickness, in piezo-electric generating structure 5, sheet metal 9 is made by the good metal material of elasticity, after piezo-electric generating structure 5 is stirred end by plectrum 4, normal position can be quickly recovered to.
When the present invention being fixed on the four limbs of human or animal, the active belt movable pendulum stone roller 2 of four limbs swings, and plectrum 4 back and forth stirs piezo-electric generating structure 5 back and forth thereupon, so piezo-electric generating structure 5 is subject to elastic deformation and produces electric energy.Because some plectrums 4 are evenly distributed on bottom the circular arc camber of pendulum mound 2, no matter pendulum mound 2 swings left or swings to the right, after a slice plectrum 4 stirs piezo-electric generating structure 5 end, another sheet plectrum 4 can stir piezo-electric generating structure 5 again subsequently, thus piezo-electric generating structure 5 produces electric energy continuously.Thin sheets of piezoelectric material 8 can be connected by the mode of series connection or parallel connection with thin sheets of piezoelectric material 10.In addition, also can place many group piezo-electric generating structures 5 in the bottom of supporting seat 1 and keep out seat 6, realizing more mechanical energy and change to electric energy.
Portable power generation device proposed by the invention adopts the mode based on piezo-electric generating structure, and whole apparatus structure is simple, compact, need not do any process additionally, compact, is easy to realize integrally-built microminiaturization and integrated.The present invention can combine use with the various wearable electronic such as intelligent watch, Intelligent bracelet or portable electric appts, by collecting energy during human or animal's activity, as a kind of green energy resource, power to various wearable electronic or portable electric appts, have broad application prospects.
With reference to Fig. 6, Portable power generation device of the present invention is powered to various electronic equipment after over commutation, voltage stabilizing, power storage.
