Abstract
The invention discloses a portable human body energy harvesting system which comprises a plurality of piezoelectric transducer modules, a rectifying module, an output module and a storage module, wherein the plurality of piezoelectric transducer modules are located at all movable parts of the human body and are sequentially connected with the rectifying module and the output module. The mechanical energy generated by the human body is converted to the electrical energy through the piezoelectric transducer modules and is rectified and transported to the storage module or the output module through the rectifying module; the storage module provides the output module with the stored energy, and the output module finally provides the energy transferred from the storage module and the piezoelectric transducer module to the load. The portable human body energy harvesting system is simple and compact in structure and high in energy harvesting efficiency.
Description
Technical field
The present invention relates to energy collecting system, particularly a kind of portable body energy collecting system.
Background technology
Along with development of technology and The development in society and economy; The H.D digital product of large-screen pours in people's life; These functions electronic product has from strength to strength also brought power consumption when being convenient for people to live significantly rising; But the battery technology of capacity aspect only increases by 6% every year, and this just needs people frequently to accompanied electronic product charging, make simultaneously outwork person for the electronic product charging bring very big inconvenience.Therefore, market is that the technology requirement of the electronic product power supply of carrying becomes bigger to collecting energy at any time.
The existing technology of physical activity generating of utilizing adopts mechanical generating apparatus to transform the mechanical energy of collection basically; The design that minority utilizes piezoelectric crystal to transform the mechanical energy of being gathered also all is confined to piezoelectric crystal is placed in the footwear heel place (patent No.: 200710158678.2).
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of do not have complex mechanical construction, simple in structure, compact, portable body energy collecting system that generating efficiency is high.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of portable body energy collecting system; It comprises some piezoelectric energy-conversion modules, rectification module, memory module and output module, and said some piezoelectric energy-conversion modules all connect rectification module, memory module and output module successively.
As further improvement of the present invention, said some piezoelectric energy-conversion modules are fixed on the movable position that physical activity produces extruding piezoelectric energy-conversion module.
As further improvement of the present invention, said piezoelectric energy-conversion module is the single or multiple lift piezoelectric ceramic.
As further improvement of the present invention, protect structure with waterproof, anti-folding etc. on the piezoelectric energy-conversion module.
As further improvement of the present invention, said storage module is electric capacity, the rechargeable battery of store electrical energy.
The invention has the beneficial effects as follows: the mechanical energy that the present invention utilizes energy collecting system that human body is produced; Change into electric energy and the rectification module rectification flows to memory module or output module through the piezoelectric energy-conversion module; Memory module offers output module with the energy of storage; The output module energy that comes of memory module and rectification module transmission the most at last offers load; This system can be incorporated in the product that power-generating shoe, generating shoe-pad, passive wrist-watch etc. and human body directly contact easily, and the piezoelectric energy-conversion module is the single or multiple lift piezoelectric ceramic piece.Said piezoelectric energy-conversion module is also with protection structures such as waterproof, anti-foldings.Lighter under the identical situation of generating capacity; Do not have obvious bascule design, can not bring sense of discomfort to the user; When output module adopts wireless mode that electric power is exported, energy-storage module can be installed, and the electronic product power supply for carrying more easily, the present invention is simple in structure, compactness, and energy acquisition efficient is high.

Embodiment
Embodiment 1:
As shown in Figure 2; Present embodiment is the application of energy collecting system in power-generating shoe; Structure is: at corresponding sites such as sole sole, heel fluting, so that piezoelectric energy-conversion module 1, rectification module 2 and memory module 4 are installed, reserved location is installed output module 3 at the upper of a shoe rear portion; The sole of common shoe-pad and trough of belt then constitutes the compressive plane and the supporting surface of piezoelectric energy-conversion module 1 respectively, and piezoelectric energy-conversion module 1 receives the alternately extruding force of sole and heel when person walks, and with its instant alternate electric energy; Alternate electric energy is through rectification module 2 direct current energies, and direct current energy is flowed to memory module 4 stores; Memory module 4 can flow to output module 3 with energy stored; At last, power to the load through wired or wireless mode by conveyor module 3.
Embodiment 2:
As shown in Figure 3; In the bonnet of wrist-watch, then paste piezoelectric energy-conversion module 1; Rectification module 2 memory modules 4 and output module 3 are installed in watchcase; Watchband and watchcase transmit a piezoelectric energy-conversion module 1 with the staff extruding force that the generation of adversary's watch back cover constantly changes when movable (comprising beat pulse) jointly, and it is immediately passed to piezoelectric energy-conversion module 1; Rectification module 2 is transformed into direct current with the alternating current that 1 conversion of piezoelectric energy-conversion module comes again, and power delivery is given memory module 4; Memory module 4 can flow to output module 3 with energy stored; At last, supply power to wrist-watch through wired or wireless mode by conveyor module 3.
More than combine the accompanying drawing specific embodiments of the invention to be described; But these explanations can not be understood that to limit protection scope of the present invention and limited the claims of enclosing, and any change on claim of the present invention basis all is protection scope of the present invention.
