Background technology
Extremely concern and the attention of countries in the world of development and utilization along with problems such as the day of the energy is becoming tight and the enhancing day by day of people's environmental consciousness, energy-conserving and environment-protective and environment friendly and pollution-free new forms of energy.Utilize device that the piezoelectric ceramic direct piezoelectric effect generates electricity because it has environmental protection and energy saving, electromagnetic interference simple in structure, no, is easy to realize, low cost and other advantages, become countries in the world researcher's the focus of attention.Utilize body kinetic energy to carry out piezo-electric generating, meet current energy conservation and environment protection, and have high economic benefit.
Study both at home and abroad to utilize body kinetic energy to carry out piezoelectric generating device more, typical in the piezo-electric generating footwear, domestic publication number is a kind of piezoelectric generating device and the electricity-generating method thereof based on human body kinetic energy stimulation that the CN101728975A patent is invented, it is a kind of piezo-electric generating composite plate of pin type, be installed on shoe-pad or sole, the portion of energy of the daily walking movement of people is converted to electric energy.But, present piezo-electric generating footwear or sheerly personal behavior of shoe-pad, generating disperses, and energy output is little, directly tramples piezoelectric ceramic piece and easily causes its damage of breaking, and economic and practical is poor.If the kinetic energy that utilizes the bigger occasion people of flow of the people such as track traffic, market, stair mouth to trample carries out piezo-electric generating, then has bigger economic benefit.
Utilize body kinetic energy to carry out the benefit of piezo-electric generating in order to improve to have now, publication number is that the patent documentation of CN201956927U discloses a kind of piezoelectric generating device that utilizes human body frequently to step on away, this device utilizes human body spring lever mechanism to be trampled the potential energy that forms spring deformation, and then the retracting spring deformation potential knocks piezoelectric and carries out piezo-electric generating, this apparatus structure is simple, cost is low, energy output is concentrated, but in experiment, find, there is certain deficiency in this device, because it is slower that human body is trampled the speed that the lever construction rear foot packs up, it is very little to the percussion power that piezoceramic material forms that spring deformation potential energy discharges the back, influenced the generating conversion efficiency of piezoelectric ceramic piece, in addition, the stroke that human body is trampled is stepped on senses of discomfort such as sky greater than 2mm.
Summary of the invention
The utility model provides a kind of novel cantilever lever piezo-electric generating assembly, purpose is to utilize body kinetic energy to carry out the conversion efficiency of piezo-electric generating in order to improve, and steps on senses of discomfort such as sky when avoiding trampling piezoelectric generating device and directly trample piezoelectric ceramic piece easily to cause its problem such as damage of breaking.
A kind of cantilever lever piezo-electric generating assembly, comprise piezo-electric generating plate, supplemental support parts and elastic lever, described piezo-electric generating plate comprises copper polar plate 2 and the square A piezoelectric ceramic piece 1 and the B piezoelectric ceramic piece 3 that stick on copper polar plate 2 upper and lower surfaces, A piezoelectric ceramic piece 1 and B piezoelectric ceramic piece 3 are all opposite along thickness direction polarization and polarised direction, and A piezoelectric ceramic piece 1 and B piezoelectric ceramic piece all are connected to power conversion circuits and energy accumulating device; The supplemental support parts comprise A supporting bracket 10, B supporting bracket 9, top board 8 and connector 7; Elastic lever comprises T type elastic rod 5, be arranged on T type elastic rod 5 upsides near the active briquetting 6 of top board 8 and be arranged on the driven briquetting 4 of T type elastic rod 5 downside ends, initiatively briquetting 6 and driven briquetting 4 are linked together by bonding or welding manner and T type elastic rod 5, initiatively briquetting 6 is 1/10 to 1/2 of T type elastic rod 5 jib-lengths to top board 8 distances, in the vertical direction, the high 0.3 ~ 1.5mm of height of aspect ratio top board 8 upper surfaces of described active briquetting 6 upper surfaces.A supporting bracket 10, copper polar plate 2, B supporting bracket 9, T type elastic rod 5 and top board 8 arrange successively from bottom to top, all offering on A supporting bracket 10, copper polar plate 2, B supporting bracket 9, T type elastic rod 5 and the top board 8 can be for the connection holes that connects usefulness, it is connected as one passed the connection holes of each part by connector 7 after.After the T of elastic lever type end was fixing by the supplemental support parts, elastic lever had just formed the cantilever lever construction, and elastic lever is fulcrum by supplemental support parts bearing, and initiatively briquetting 6 is power arm to the fulcrum section, and driven briquetting 4 is resistance arm to the fulcrum section.
When the people tramples the active briquetting 6 of T type elastic rod 5 upsides, according to lever principle, the driven briquetting 4 that is arranged on T type elastic rod 5 downsides will move down the distance that moves down more than active briquetting 6, namely only need active briquetting 6 is trampled very little distance downwards, can drive piezo-electric generating plate one end and be bent downwardly bigger distance and realize body kinetic energy to the power conversion of electric energy, thereby improve the piezoelectricity conversion efficiency of piezo-electric generating plate.After human body was trampled end release active briquetting 6, T type elastic rod 5 returned to original shape, and driven briquetting 4 and copper polar plate 2 break away from, and when human body was trampled continuously and discharge active briquetting 6, this piezo-electric generating assembly can be finished continuous piezo-electric generating process.
Because the support limit effect of top board 8, restriction active briquetting 6 and human body only can move down 0.3 ~ 1.5mm, and distance is shorter, do not have senses of discomfort such as stepping on sky, and have avoided human body and the direct of piezoelectric ceramic to contact, and guarantee that piezoelectric ceramic is not by concussion fracture or damage.Compared with prior art, this cantilever lever piezo-electric generating assembly have that simple in structure, power capacity is big, complete machine manufacturing assembling easily, cost low, piezoelectricity conversion efficiency height, the not fragile fragmentation of piezoelectric ceramic, do not have advantages such as sense of discomfort, environmentally safe, long service life such as the sky of stepping on when trampling.
