Therefore, the present invention have low cost, safe and reliable, be convenient to the advantages such as movement, sustainable power supply.
Realize the function that mobile phone can be realized in the technology before cell-phone function on the universal significance refers to the applying date, contribution of the present invention mainly is to provide circuit by the motion automatic charging for mobile phone, but not other function of mobile phone, thereby do not do too much statement for other function of mobile phone.All lean on the principle of the circuit of motion automatic charging based on the present invention is all being within the scope of the present invention of cell-phone charging.
The schematic diagram of a kind of mobile phone by the motion automatic charging of the present invention design comprises handset and is the circuit of charging mobile phone battery by moving as shown in Figure 1.
Described handset is used for the cell-phone function on the realization universal significance, and acceleration transducer and software platform is provided.
Described by the motion for the circuit of charging mobile phone battery as shown in Figure 2, comprise electric energy production part, filter circuit, ON-OFF control circuit, level shifting circuit and battery of mobile phone.
Described electric energy production part comprises coil L and magnet M, is used for the variation by magnetic flux of the kinetic energy of magnet movement is converted to electric energy, passes to described filter circuit.
Described filter circuit, comprise the first diode D1, the second diode D2, the 3rd diode D3, the 4th diode D4 and capacitor C, wherein diode D1, D2, D3, D4 form a bridge rectifier, the AC rectification that described electric energy production part is produced is direct current, and capacitor C is further level and smooth for the direct current that will produce.

Described level shifting circuit comprises a level transferring chip, is used for the direct current that described filter circuit produces is carried out level conversion, makes the level after the conversion can satisfy the required charging voltage of battery of mobile phone, is suitably for charging mobile phone battery.
The concrete connected mode of circuit is: the end of coil L links to each other with the anode of diode D1 and the negative terminal of diode D2 respectively, and the other end of coil L links to each other with the anode of diode D3 and the negative terminal of diode D4 respectively; The negative terminal of diode D1 links to each other with an end of capacitor C, the negative terminal of diode D3 and an end of K switch respectively, the other end of K switch links to each other with an input of level transferring chip, and the anode of diode D4 links to each other with the anode of diode D2, the other end of capacitor C and another input of level transferring chip respectively; Two outputs of level transferring chip link to each other with the both positive and negative polarity of battery of mobile phone respectively.
Specific works mechanism is as follows:
1, coil L is fixed in the handset, and the two ends of magnet M are fixed by spring, can move back and forth in L with the motion of mobile phone, produces the variation of magnetic flux, thereby produces alternating current by electromagnetic induction phenomenon.According to Faraday's electromagnetic induction law, induced electromotive force is
Wherein, E is induced electromotive force, and n is the number of turn of coil L, and Δ φ is the variable quantity of magnetic flux, and Δ t is the variable quantity of time.By (1) formula as can be known, when number of turn n faster when magnet movement, coil L was larger, the induced electromotive force E of generation was just larger.
What 2, export from coil L is an alternating voltage because charging mobile phone battery needs a direct voltage, so the alternating voltage that produces of coil L after filtration wave circuit be converted to galvanic current and press.Connecting a smoothing capacity C behind the bridge rectifier that filter circuit is comprised of diode D1, D2, D3, D4 forms.Through behind the bridge rectifier, coil output voltage is converted to a direct voltage, but this direct voltage and unstable, has very large fluctuation, therefore behind bridge rectifier, connect a smoothing capacity C, further level and smooth to the direct voltage that produces, export a galvanic current and press.
3, connecting valve K behind the filter circuit, the acceleration transducer that this switch is carried by handset is controlled.Can produce acceleration during the mobile phone motion, this moment, K switch was closed, and circuit working is charging mobile phone battery; When mobile phone is static, there is not acceleration to produce, this moment, K switch disconnected, and circuit is not worked, and is not charging mobile phone battery; Simultaneously, because mobile phone when static, does not have the generation of induced electromotive force, can not give charging mobile phone battery.In addition, can also K switch be set to reaction time and the sensitivity of acceleration change by software, make its can not disconnect continually, closed and cause circuit frequently to switch, guarantee the useful life of circuit and battery of mobile phone.
4, the stable DC voltage of filter circuit generation, because voltage does not mate can not be directly to charging mobile phone battery, therefore will be through a level transferring chip, the direct current that filter circuit is produced carries out level conversion, make the level after the conversion be suitably for charging mobile phone battery, and battery of mobile phone is not caused damage.
By motion for the circuit of charging mobile phone battery at the voltage waveform view of stages output as shown in Figure 3.
Than prior art, the present invention has following beneficial effect:
1, realized by motion the mobile phone automatic charging;
What 2, the electric energy production part used is coil, magnet, and cost is very low;
3, the control of charging circuit can be controlled by the automatic induction acceleration of acceleration transducer, also can control by the software setting, and is convenient and swift;
4, by motion the mobile phone of mobile phone automatic charging is not needed to increase large-area unnecessary parts, be easy to carry, fail safe is good, and is not subjected to the restriction of time and place to use.
Day by day increase along with the smart mobile phone function, we are to constantly increasing degree of dependence and the service time of mobile phone, the problem that battery of mobile phone can not be powered for a long time needs to be resolved hurrily, develop a kind of mobile phone that can power for a long time and become inevitable development trend, therefore, the mobile phone by the motion automatic charging of the present invention's proposition has the very strong market competitiveness.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
