Be example with the ultracapacitor with the energy-storage travelling wave tube in the energy storage device below, introduce two kinds of possible structures of above-mentioned energy storage device 12 in detail.
The self-powered that Fig. 2 a provides for the utility model is located a kind of circuit theory synoptic diagram of energy storage device in the footwear.The inner structure that Fig. 2 a shows energy storage device with and with the annexation of nano friction generator 11.Shown in Fig. 2 a, energy storage device comprises: rectification circuit module 51, filtering circuit module 52 and ultracapacitor 54.Wherein, rectification circuit module 51 links to each other with the output terminal of nano friction generator 11, and the electric signal that nano friction generator 11 is exported carries out the rectification processing.Particularly, two input end 51A of rectification circuit module 51 and 51B are connected two output terminals of nano friction generator respectively, receive the electric signal of nano friction generator 11 outputs.For comprising a plurality of nano friction generator Structure, two output terminals of a plurality of nano friction generators are connected in parallel, and are connected with 51B with two input end 51A of rectification circuit module 51 then.
Two output terminal 51C of rectification circuit module 51 are connected with filtering circuit module 52 with 51D, and the unidirectional Rectified alternating current that the electric signal that rectification circuit module 51 is exported nano friction generator 11 carries out obtaining after rectification is handled is exported to filtering circuit module 52.Filtering circuit module 52 is connected with ultracapacitor 54, and filtering circuit module 52 is carried out filtering with the unidirectional Rectified alternating current of rectification circuit module 51 output and handled and obtain dc signal and export to ultracapacitor 54.

For the circuit shown in Fig. 2 a, when external force acts on the nano friction generator, can make nano friction generator generation mechanical deformation, thereby produce the pulse electrical signal that exchanges.The pulse electrical signal of this interchange at first inputs to the rectification circuit module, by the rectification circuit module it is carried out rectification, obtains the direct current of unidirectional pulsation.The direct current of this unidirectional pulsation inputs to the filtering circuit module again and carries out filtering, and the interference noise in the direct current of unidirectional pulsation is carried out filtering, obtains dc signal.At last, this dc signal directly inputs to ultracapacitor and charges.Here can also can charge simultaneously for the ultracapacitor of a plurality of parallel connections for a ultracapacitor charging.
The advantage of foregoing circuit is: (1) produces the size of electric energy and the size of ultracapacitor electric capacity and charging voltage according to the nano friction generator, by regulating the correlation parameter of filtering circuit module, make it possible to the electric energy that utilizes the nano friction generator to produce to greatest extent, improve energy conversion efficiency; (2) according to the difference of applied environment, the voltage amplitude scope that the nano friction generator produces is bigger, can it be adjusted into adaptation to the voltage of ultracapacitor charging by regulating the correlation parameter of filtering circuit module, overcome the uncertainty that the nano friction generator produces voltage swing.
Further, energy storage device can also adopt a kind of more preferred construction.The self-powered that Fig. 2 b provides for the utility model is located the another kind of circuit theory synoptic diagram of energy storage device in the footwear.The inner structure that Fig. 2 b shows preferred energy storage device with and with the annexation of nano friction generator.Shown in Fig. 2 b, energy storage device also comprises charge control module 63 and switch/transformation module 64 except comprising rectification circuit module 61, filtering circuit module 62 and ultracapacitor 65.Wherein the function of rectification circuit module 61 and filtering circuit module 62 repeats no more referring to above.
Charge control module 63 is connected with filtering circuit module 62, the d. c. voltage signal U1 of circuit module 62 outputs that accept filter; Charge control module 63 is connected with ultracapacitor 65, receives the charging voltage U of ultracapacitor 65 feedbacks; Charge control module 63 also is connected with switch/transformation module 64, and charge control module 63 is according to d. c. voltage signal U1 and the controlled signal of charging voltage U, to switch/transformation module 64 output control signals.Switch/transformation module 64 is connected with filtering circuit module 62, the d. c. voltage signal U1 of circuit module 62 outputs that accept filter; Switch/transformation module 64 also is connected with ultracapacitor 65, switch/transformation module 64 is carried out the switch switching and the d. c. voltage signal of filtering circuit module 62 outputs is regulated processing according to the control signal that receives, and is adjusted to adapt to the voltage U 2 of giving ultracapacitor 65 chargings.
For the circuit shown in Fig. 2 b, different with Fig. 2 a is, handle the d. c. voltage signal U1 that obtains through filtering and input to charge control module 63, charge control module 63 can decide and when ultracapacitor 65 be charged according to the size of this d. c. voltage signal U1; And ultracapacitor 65 charge conditions are paid close attention to, come gauge tap/transformation module 64 according to the situation of ultracapacitor 65 chargings.The output voltage of wave circuit module 62 is output voltages that progressively increase after filtration, and this output voltage is up to increasing to pressure limiting voltage, and this pressure limiting voltage is a circuit protection voltage, prevents that circuit from damaging because of overtension.
Because whole charging circuit module does not have external power supply, it also is to come from nano friction generator electricity that charge control module 63 gauge tap/transformation module 64 is given the working power of ultracapacitor 65 chargings, therefore specially in charge control module 63 trigger voltage is set, after filtering circuit module 62 output voltages reached this trigger voltage, charge control module 63 just driving switch/transformation module 64 started charging.
Another effect of charge control module 63 is according to the size of the d. c. voltage signal U1 that obtains through filtering and the size of ultracapacitor 65 charging voltage U, U1 regulates to d. c. voltage signal, be adjusted to the voltage U 2 that adapts to ultracapacitor 65 chargings, and selectivity driving switch/transformation module 64 gives ultracapacitor 65 chargings.
According to C=Q/U as can be known, the capacity C of ultracapacitor is a fixed value, and in the process to the ultracapacitor charging, quantity of electric charge Q is in continuous increase, and the voltage U of ultracapacitor is also in continuous rising thereupon.Charge to ultracapacitor for more effective, charge control module 63 is according to the numerical information of the d. c. voltage signal U1 of the charging voltage U of ultracapacitor 65 feedback and 62 outputs of filtering circuit module, come the circuit in by-pass cock/transformation module 64, realization obtains the real time charging voltage U 2 of ultracapacitor 65 to the conversion of voltage U 1 to U2.A corresponding charging matching relationship is arranged, to guarantee the highest energy conversion efficiency between U2 and the U.For instance, suppose that the voltage that is full of of ultracapacitor 65 is U0, charge control module 63 compares charging voltage U and the U0 of ultracapacitor 65 feedbacks, if U, shows ultracapacitor 65 also underfills less than U0, needs to continue charging; If U equals U0, show that ultracapacitor 65 has been full of.Simultaneously, charge control module 63 also compares d. c. voltage signal U1 and the U0 of 62 outputs of filtering circuit module, if U1 is greater than U0, then charge control module 63 output control signal gauge tap/64 couples of U1 of transformation module carry out the step-down processing, obtain the real time charging voltage U 2 of ultracapacitor 65; If U1 is less than U0, then charge control module 63 output control signal gauge tap/64 couples of U1 of transformation module processing of boosting obtains the real time charging voltage U 2 of ultracapacitor 65.
Here can be a ultracapacitor charging, also can as Fig. 2 b, show three ultracapacitors for a plurality of ultracapacitor chargings, these three ultracapacitors are connected in parallel.When being the charging of a plurality of ultracapacitors, can be full of one by one, also can be full of simultaneously.Be full of in the following manner one by one and realize: the charging voltage U that charge control module 63 is fed back the current ultracapacitor that is charging is full of voltage U 0 and compares with it, if U has reached U0, charge control module 63 output control signal gauge tap/transformation modules 64 switch to next ultracapacitor with switch, continue as next ultracapacitor and charge so.
Further, in order to protect the nano friction generator, energy storage device can also comprise generator control module 66.This generator control module 66 is connected with ultracapacitor 65, receives the charging voltage U of ultracapacitor 65 feedbacks; Generator control module 66 also is connected with the nano friction generator, exports the signal that stops to generate electricity to the nano friction generator.When ultracapacitor 65 is full of, can obtain one and be full of voltage, this is full of voltage and feeds back to generator control module 66, and then generator control module 66 can close the nano friction generator, thereby stops generating.
The advantage of the circuit shown in Fig. 2 b is: (1) is owing to the external force size that acts on the nano friction generator is uncertain, the alternating current size that makes the nano friction generator produce is also uncertain, this circuit can convert uncertain magnitude of voltage to the magnitude of voltage that is fit to the ultracapacitor charging, adaptability is strong, has expanded the application of self-charging ultracapacitor; (2) owing to designed charge control module especially in the circuit, regulate its charging voltage according to the real-time voltage of ultracapacitor, make real-time voltage and the charging voltage of ultracapacitor keep a dynamic matching relationship, reach the electric energy that the nano friction generator is sent and filled to greatest extent and given ultracapacitor, realized maximum energy storage effect; (3) according to being full of of ultracapacitor, whether the work of generator control module control nano friction generator, and then prolong the serviceable life of nano friction generator; (4) when charging for a plurality of ultracapacitors, when one of them is full of, can automatically switches to next ultracapacitor and charge.
After having introduced the implementation of power module, continuation is with reference to Fig. 1, central processing module 2 links to each other with wireless communication module 4 with GPS locating module 3 respectively, being used for control GPS locating module 3 positions, and the locating information that GPS locating module 3 is produced offers wireless communication module 4, by wireless communication module 4 above-mentioned locating information sent to predetermined receiving end.

In the mode that initiatively triggers, need an alarm switch 5 be set at the footwear body of location footwear, this alarm switch 5 links to each other with central processing module 2, is used for central processing module 2 is triggered.When central processing module 2 receives the triggering of alarm switch 5, then control GPS locating module 3 and position.Wherein, alarm switch can be one or more in the following type: snap switch, pushbutton switch, vibration switch and audio-switch.If alarm switch is snap switch or pushbutton switch, then when the user pushed for emergency switch, alarm switch can send a trigger pip from the trend central processing module, and central processing module is controlled the GPS locating module according to this trigger pip and positioned; If alarm switch is vibration switch or audio-switch, then the vibrations degree when the location footwear exceeds default vibrations threshold value, when perhaps the frequency of ambient sound exceeds the frequency preset threshold value, alarm switch can send a trigger pip from the trend central processing module, and central processing module is controlled the GPS locating module according to this trigger pip and positioned.Initiatively the mode that triggers can be by the user in lost or triggered location function on one's own initiative when facing a danger, to obtain rescue.This mode is applicable to user's freedom of action and the situation that can initiatively trigger.
In the mode of passive triggering, when needs position the user, send the positioning control signal by external unit (for example mobile phone, pager etc.) to the wireless communication module of footwear inside, location by kith and kin or police.Wireless communication module is transmitted to central processing module with it after receiving this positioning control signal, and central processing module is controlled the GPS locating module and positioned after receiving this positioning control signal.The mode of passive triggering can initiatively not initiated when contacting the user by kith and kin, in order to know user's whereabouts.This mode is applicable to the situation that the user is handicapped and can't initiatively trigger.And this mode is specially adapted to suffer from the old man of senile dementia or the child who runs away from home.When the control that is subjected to central processing module when the GPS locating module positions, at first need to catch gps satellite signal, and position calculating according to the satellite-signal that captures, thereby obtain the residing positional information of user, also be locating information, and this locating information offered wireless communication module by central processing module, by wireless communication module this locating information is sent to predetermined receiving end.Wherein, can carry out with reference to the locator meams of routine according to the detailed process that gps satellite signal positions, repeat no more herein.In addition, because location Calculation is a kind of very complicated calculating, so positioning when calculating, the GPS locating module need expend a large amount of electric energy, therefore, preferably can adopt a kind of cloud GPS technology in the utility model, the calculation task of complexity is transferred to large-scale high in the clouds server process, thereby reduce the calculated amount of GPS locating module, saves energy.
Wireless communication module sends to above-mentioned locating information the predetermined receiving end except being used for, and can also send alerting signal to predetermined receiving end simultaneously, in order to arouse attention.Wherein, predetermined receiving end can be this location footwear user's kith and kin's mobile phone, perhaps, also can be the phone etc. of local police station, and for this reason, needs be stored in kith and kin's cell-phone number or the telephone number of local police station in the wireless communication module 4 in advance.In addition, can also be the receiving end of emergency telephone number correspondence, for example, wireless communication module 4 will be called out 110 emergency numbers such as grade, and be transferred to 110 nearest information desks automatically.And, can in time obtain rescue in order to ensure the user, this predetermined receiving end can be a plurality of, for example, can send locating information to a plurality of kith and kin respectively.Wherein, the delivery form of locating information can arrange as required flexibly, for example, can transmit by short message, also can transmit by voice, can also transmit by short message and voice simultaneously.

Among the utility model embodiment, power for the location footwear by the nano friction generator, to realize positioning function.Because the nano friction generator can be converted to electric energy with mechanical energy, thereby realize self-energizing, need not battery or external power supply, thereby the problem that can not in time power when having avoided power supply to exhaust.And because wireless communication module can initiatively receive the positioning control signal that kith and kin send, thereby when the user can't initiatively position because of fortuitous event, the external world also can relate to the user of these location footwear, thereby succours.
In the above-described embodiments, the nano friction generator is core component, just because of the spontaneous electrical function of nano friction generator, just makes the location footwear be achieved self-powered.Following mask body is introduced nano friction generator Structure and principle of work wherein.
First kind of structure of nano friction generator is shown in Fig. 3 a and Fig. 3 b.Fig. 3 a and Fig. 3 b show perspective view and the cross-sectional view of first kind of structure of nano friction generator respectively.This nano friction generator comprises: first electrode, 111, the first high molecular polymer insulation courses 112 that are cascading, and second electrode 113.Particularly, described first electrode 111 is arranged on first side surface of the first high molecular polymer insulation course 112; And the surperficial contact friction of second side surface of the described first high molecular polymer insulation course 112 and second electrode 113 also induces electric charge at second electrode and the first electrode place.Therefore, above-mentioned first electrode and second electrode first output terminal and second output terminal that also can be called the nano friction generator respectively.
In order to improve the generating capacity of nano friction generator, at second side surface (being on the face of relative second electrode 113) of the first high molecular polymer insulation course 112 micro-nano structure 120 can be set further.Therefore, when the nano friction generator is squeezed, apparent surface's contact friction better of the described first high molecular polymer insulation course 112 and second electrode 113, and induce more electric charge at first electrode 111 and second electrode, 113 places.Because the second above-mentioned electrode is mainly used in and the friction of the first high molecular polymer insulation course, therefore, second electrode also can be referred to as the electrode that rubs.
Above-mentioned micro-nano structure 120 specifically can be taked following two kinds of possible implementations: first kind of mode is that this micro-nano structure is micron order or nano level very little concaveconvex structure.This concaveconvex structure can increase frictional resistance, improves generating efficiency.Described concaveconvex structure can directly form when film preparation, and method that also can enough polishings makes the surface of the first high molecular polymer insulation course form irregular concaveconvex structure.Particularly, this concaveconvex structure can be the concaveconvex structure of semicircle, striated, cubic type, rectangular pyramid type or shape such as cylindrical.The second way is, this micro-nano structure is the poroid structure of nanoscale, this moment, the first high molecular polymer insulation course material therefor was preferably Kynoar (PVDF), and its thickness is the preferred 1.0mm of 0.5-1.2mm(), and the face of its relative second electrode is provided with a plurality of nano-pores.Wherein, the size of each nano-pore, namely width and the degree of depth can be selected according to the needs of using, and preferred nano-pore is of a size of: width is that 10-100nm and the degree of depth are 4-50 μ m.The quantity of nano-pore can as required output current value and magnitude of voltage be adjusted, and preferably these nano-pores are that pitch of holes is the even distribution of 2-30 μ m, and preferred average pitch of holes is the even distribution of 9 μ m.
Following mask body is introduced the principle of work of above-mentioned nano friction generator.When crooked under each course of this nano friction generator, second electrode in the nano friction generator produces static charge with the first high molecular polymer surface of insulating layer phase mutual friction, the generation of static charge can make the electric capacity between first electrode and second electrode change, thereby cause electric potential difference occurring between first electrode and second electrode, thereby free electron will be by first electrode and second electrode respectively by the low effluent of electromotive force to the high side of electromotive force, thereby in external circuit, form electric current.In addition, when each layer of this nano friction generator returns to original state, at this moment the built-in potential that is formed between first electrode and second electrode disappears, to again produce reverse electric potential difference between Balanced first electrode and second electrode this moment, and then free electron forms inverse current by external circuit.By repeated friction and recovery, just can in external circuit, form periodic ac signal.
