Description
Technical field
The utility model is a kind of illuminating flashlight, is specifically related to a kind of flashlight of self power generation.
Background technology
At present, the flashlight of general people's use mostly adopts disposable dry cell to provide illumination power as power supply.This flashlight needs often to change battery because its battery is short service life, and is uneconomical.When people travel outdoors and can't in time change battery the time, just lose due illuminating effect, gone out to make troubles.When flashlight does not use for a long time and when having forgotten battery taken out, can cause the electrolyte in the battery to separate out, and corrosion damages flashlight.In addition, old and useless battery can bring great pollution to environment.
Now, but the flashlight of some self power generations has also appearred on the market.These flashlights are converted into electric energy by the clockwork spring of pushing or set of hand with kinetic energy.Rely on the holding with a firm grip of hand, unclamp power to torch is provided, the light that torch sends is intermittently shape, not too adapts to for hand or the not strong colony of finger strength.By pushing or a lighting hours length of the flashlight of clockwork spring generating is subjected to the restriction of external force size or clockwork spring structure, can not long-time continuous use.
Summary of the invention
The purpose of this utility model provides a kind of utilization and simply shakes and generate electricity, and the flashlight that electrical power storage is got up.
Based on above-mentioned purpose, the utility model is achieved in that
A kind of rear-mounted hand flashlight with electric generation by itself includes housing, reflective mirror, switch, folding wind, it is characterized in that also including one or more groups light emitting source, and the inside of housing and bottom are provided with TRT and the energy storage device that kinetic energy is converted into electric energy.Above-mentioned TRT comprises folding wind, speed increasing gear group, generator and circuit board.Energy storage device is one or more chargeable batteries, also can be one or more electric capacity.Drive the running of speed increasing gear group by folding wind, the speed increasing gear group will be rotated the kinetic energy that is produced again and be passed to generator, generator after the work is converted into AC energy with kinetic energy, by circuit board alternating current is become direct current again, fill at last and store up in chargeable battery or the electric capacity, but so just provide stabilized power source that its long period is used continuously to flashlight.
When energy storage device is electric capacity, can prolong the service life of flashlight.Because chargeable battery through use year in year out after, the internal resistance meeting increases, and makes that can store electric weight descends, thereby has influenced lighting hours.And jumbo electric capacity just can be avoided above defective.
The shape of flashlight housing can be cylindrical also can be other shapes such as cuboid.When adopting when cylindrical,, kept traditionally people that flashlight use habit in shape is convenient to hand-held long-time the use only in the side, bottom or directly be provided with folding crank handle in the bottom.
In the rear-mounted hand flashlight with electric generation by itself two groups of light emitting sources can be set.Arranging a plurality of light emitting sources along periphery below the single light emitting source of center and the reflective mirror below the reflective mirror can be lighted by switch in timesharing, also can be lighted by switch simultaneously.The user can control lamplight brightness by switch according to the illumination needs of oneself, can satisfy oneself illumination needs like this, prolongs lighting hours again as far as possible.Through experiment, if only with the single light emitting source illumination in center, crank handle changes 100 circles, just can use about 1.5～2 hours.
Be provided with the whether full suggestion device of expression charge volume in the rear-mounted hand flashlight with electric generation by itself.This suggestion device can comprise counter and display, also can be buzzer or light emitting diode.The user as long as arbitrarily shake folding crank handle, needn't remember the revolution that shakes just can know clearly whether be full of in when charging.
Advantage of the present utility model is:
1. can charge at any time as required, also can arbitrarily set the rechargeable electrical energy size according to the revolution that shakes.
2. but can provide stabilized power source and long period to use continuously.
3. can control lamplight brightness according to the needs of illumination, be fit to the illumination under the multiple bright and dark light condition.
4. keep traditionally people to flashlight use habit in shape, be convenient to hand-held long-time the use.
