Description

A kind of multimode prisoner energy self-powered laser pen
Technical field
The utility model is related to a kind of multimodes to capture energy self-powered laser pen, belong to energy collection technology application field.
Background technology
With the increase of population and continually developing for the energy, many non-renewable energy resources are all suffered from following century-old exhausted The case where, thus caused by problem of environmental pollution also become increasingly conspicuous, so researcher constantly look for it is a kind of new and effective The Energy harvesting methods of environmental protection.
Energy collection technology be by various energy utilizations in nature and collect give apparatus and system power supply, with the epoch Progress, energy extended to present luminous energy, electromagnetic energy, tide energy, nuclear energy etc. from traditional energy.And it is protected for environment The purpose of shield, the part energy can all bring different degrees of pollution to natural world in the process using with utilization, so, herein There is prodigious development space in field.
Miniature energy collection technique is mainly used in the wireless sensor network of Internet of Things, implantable medical monitors, is active Radio frequency sensor and identification etc..Currently, above each industry such as wireless sensor network is being rapidly developed in China, and this A little to apply in terms of the maintenance of battery and replacement that there is inevitable bottlenecks, this also results in energy collection technology in Internet of Things The indispensable property of net application.It is contemplated that in the near future, energy collection technology will become Chinese Internet of Things field Important technology.
Texas Instrument (TI) battery management market is thought with application manager doctor Wen Sihua, as consumer, industrial class, medical treatment Class, automotive-type product in, power supply be it is ubiquitous, really and our projects today are relevant be how to adapt to it is more extensive or More extreme application scenarios, these scenes are the basic trends of consumer product, and more capacity battery is not for certain producers It is particularly suitable, this battery is stored even without space, let alone quick charge is carried out to battery, than being more typically medical treatment, storehouse The sensor network of storage, the application of Internet of Things or even wearable monitoring, these applications are difficult to obtain continued power, can only Energy is obtained from ambient enviroment or sensor.
In addition, when main power source is unavailable, energy acquisition helps to extend the run time of equipment.Portable device is exactly It is required that extend a kind of major domain of run time, such as phone, multimedia player, hand-held radio-frequency apparatus, POS scanners, just Take formula Medical Devices, tool, electric saver etc..It is very problematic for mobile phone charging, because not being in some emerging nations Power supply can be found at any time.Therefore, energy acquisition just becomes to be highly desirable, and energy acquisition is than installing a whole set of electricity Net is cheaply very much.
It is directed to piezoelectric energy collection technique, nearly ten years, domestic and foreign scholars propose a large amount of piezoelectric beams, plate energy accumulator Model, modeling analysis has obtained analytic solutions or numerical solution, and is optimized from the following aspect:Piezoelectricity list bilayer, double piezoelectric layers Connection in series-parallel, matrix geometric parameter(Length, width, shape), piezoelectric layer position, electrode shape position, external excitation, output circuit Optimum resistance etc., theoretical model is modified finally by experiment, to find accurate solution.Document is summarized it is found that pressing at present The key points and difficulties problem that electric oscillation energy acquisition mainly considers has:Device maximum electric energy output under given environmental condition, Mechanics tuning and electricity tuning, the extension of response band, the influence of non-linear factor under the conditions of varying environment etc..2007 Year, Anton and Sodano point out that most research concentrates on to the commentary review of energy harvester made of piezoelectric material Physics and geometry design and adaptive circuit improve, and its facing challenges is the electric energy generated and energy-storage travelling wave tube itself Energy consumption.Research theme is to complete practicability device(Electric energy acquisition, the combination of storage and application circuit)Transformation is new hair Open up direction.
In recent years, domestic and foreign scholars catered to electric energy acquisition new development direction, for energy storage circuit and memory element into Numerous studies are gone.Scientific research finds to improve energy acquisition efficiency up to 400% by DC-DC conversion circuits, in addition one synchronize Charge storage technology, referred to as inductance synchronous switch energy storage technologies, referred to as SSH I, by theoretical and experimental study, Its comparison with standard energy acquisition circuit energy transmission efficiency can be improved 400%.And result of study show by introduce SSH I and Electricity storage efficiency of the electricity storage efficiency of DC-DC storage circuits higher than only one of which circuit.About memory element, Have obviously relative to rechargeable nickel-hydrogen battery, chargeable lithium ion research shows that super capacitor has as energy storage elements Advantage.
In terms of laser pen field, appear on the market at present only wired charging formula and battery type two major classes, and for utilize with Self-powered laser pen patent based on piezoelectric energy-capturing and magnetic energy conversion does not have, and domestic also there are no the publications of correlative theses.It passes The two major classes laser pen of system all haves the shortcomings that more or less:Wired charging formula laser pen is inconvenient using process, in face of being permitted More urgent emergency cases must look for the supplement of socket progress electricity to maintain its normal work once electric energy exhausts;Battery type Laser pen does not cater to current social development trend, needs the replacement for carrying out battery just will be to society once battery is dealt with improperly Environment bring pollution.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and providing a kind of multimode prisoner can confess Electric shock light pen comprehensively utilizes the confession power technology based on piezoelectric energy-capturing and magnetic energy conversion, using magnet cutting magnetic induction line and Piezoelectric patches slight deformation collects energy, and energy composite energy is collected so that energy conversion efficiency and stability are all significantly carried Height meets the low-carbon theory of the environmentally protective development of society.
In order to solve the above technical problems, the utility model provides a kind of multimode prisoner energy self-powered laser pen, including laser pen Ontology, characterized in that be equipped with electromagnetism in the laser pen ontology and capture energy device and piezoelectric energy trapping device, electromagnetism prisoner can fill Set and be connected respectively with AC/DC diode rectifiers with piezoelectric energy trapping device, the AC/DC diode rectifiers successively with DC/DC converters, energy storage device, laser controller are connected, and the laser controller is connected with the DC/DC converters It connects.
