Abstract

The invention provides an LED (light-emitting diode)-based self-power generation key identifier which comprises a housing, wherein a direct current motor, a rechargeable battery and a double-layer gear are mounted in the housing, a driving gear is arranged on a shaft of the direct current motor, the driving gear is meshed with a lower gear of the double-layer gear, the driving motor is connected with the rechargeable battery, LED lamps are arranged on the housing, the rechargeable battery is connected with the LED lamps through a switch, the LED-based self-power generation key identifier further comprises a pressing type lever, one end of the pressing type lever is hinged on the housing, a return spring is further arranged at the end, and a rack meshed with an upper gear of the double-layer gear is arranged at the other end of the pressing type lever. The LED-based self-power generation key identifier can transform mechanical energy obtained by compressing the pressing type lever by the human hand to electrical energy through electromagnetic induction principle, thereby lighting the LED lamp in different color and selecting a correct door-opening key according to the different light.

Description

LED-based self power generation key identifier
Technical field
What the present invention relates to is a kind of self-generating device, particularly a kind of self-generating device that is applied to key identification.
Background technology
At present in the place that night illumination is popularized as yet, be in and select the correct key that opens the door among the dark and exist certain degree of difficulty.The mode that solves the problem of opening the door in the dark at present is mainly external light source illumination or enumerative technique.There are problems such as consumes energy, key length access time in said method.How conveniently to select correct key in the dark, become one of problem demanding prompt solution.In core periodical and patent inquiry, all do not find to invent therewith similar equipment introduction at present.
Summary of the invention
The object of the present invention is to provide and a kind ofly can choose the LED-based self power generation key identifier of providing convenience, not needing to install battery for key in the dark.
The object of the present invention is achieved like this:
Comprise housing, direct current generator, rechargeable battery and double-layer gear are installed in housing, have driven wheel on the direct current arbor, driven wheel is meshed with the lower gear of double-layer gear, and drive motors links to each other with rechargeable battery, and housing is provided with the LED lamp, rechargeable battery is connected with the LED lamp by switch, also comprise the pressing lever, an end of pressing lever is hinged on the housing and is provided with back-moving spring, the tooth bar of the other end of pressing lever for being meshed with cogging of double-layer gear.
The present invention can also comprise:
1, a side of housing is provided with pressing lever locking buckle.
2, be connected with key chain on the housing.
3, an end of described key chain is the inner keyed end that is provided with back-moving spring, and the other end has the bullet knob.
4, described key chain comprises a plurality ofly, and each key chain goes out corresponding LED lamp, each LED lamp parallel connection.
5, the color difference of each LED lamp.
The present invention can solve in the dark that key is chosen inconvenience, there are problems such as power consumption in lighting apparatus.
Self power generation of the present invention system compresses the mechanical energy that the pressing lever obtained with staff to be converted into electric energy by electromagnetic induction principle.The electric energy that the self power generation system produces is chosen the correct key that opens the door in order to light the LED modules with different colors lamp according to different lights.
Characteristics of the present invention mainly comprise:
1, the key identifier can be used as key chain and is easy to carry.
2, required electric energy is supplied with by self-generating device, energy-conserving and environment-protective and with low cost.
Description of drawings
Fig. 1 self power generation key identifier fundamental diagram;
Fig. 2 self power generation key identifier structural representation.
The specific embodiment
For example the present invention is done more detailed description below in conjunction with accompanying drawing:
In conjunction with Fig. 1, electricity generating principle of the present invention is in by the coil cutting direct current that rotating excitation field produced with eight magnetic pole direct current generator U1 battery U2 being charged.Closing Switch K1 lights LED lamp L1, L2, L3 work.
In conjunction with Fig. 2, the structure of first kind of embodiment of the present invention is formed and is comprised housing, eight magnetic pole direct current generators 4, rechargeable battery 6 and double-layer gear are installed in housing, have driven wheel 5 on the direct current arbor, driven wheel is meshed with the lower gear 2 of double-layer gear, the electricity output of drive motors links to each other with rechargeable battery, housing is provided with the LED lamp, rechargeable battery is connected with the LED lamp by switch 7, also comprise pressing lever 1, one end of pressing lever is hinged on the housing, the tooth bar of the other end of pressing lever for being meshed with cogging of double-layer gear.
Second kind of embodiment of the present invention is on the basis of first kind of embodiment, is provided with pressing lever locking buckle 8 in a side of housing.
The third embodiment of the present invention is on the basis of first kind or second kind embodiment, is connected with key chain 9 on housing.One end of key chain has bullet knob 11 for the inner keyed end 10 that is provided with back-moving spring, the other end.Key chain can comprise a plurality of, and each key chain goes out corresponding LED lamp, each LED lamp parallel connection.The color difference of each LED lamp.
Self-generating device operating principle of the present invention is when device needs work, and staff compression pressing lever 1, lever 1 drive double-layer gear 3 rotations that cog.With the 3 double-layer gear lower gears that contact, 2 driven gears, 5 rotations that cog.Gear 5 rotations drive the rotation of eight magnetic pole direct current generators, 4 magnetic poles.In coil, produce electric energy according to the right-hand rule.Direct current generator produces electric energy rechargeable battery 6 is charged.Closing Switch 7, battery 6 work are in order to light the LED lamp.Back-moving spring is settled on lever 1 top, just automatically resets after each compression finishes.When need not work, lever 1 is fixing by locking buckle 8.The keyed end 10 of key chain 9 is moved down and key chain 9 is passed key, the key installation.Fixed end 10 inside have back-moving spring, and can automatically reseting after key is put into, it is fixing to be played knob 11 simultaneously.
