Wherein, 2 hydraulic bags 13 have certain toughness and elasticity, are located at forefoot and the rear heel position of sole respectively Put, internal memory contains liquid, deform under applied external force extruding, discharge internal liquid, human foot is trampled conversion of motion is The kinetic energy of liquid.Human foot trample motion there is the characteristic that displacement is little, momentum is big, directly using this motion mechanical energy Lai Carry out generating difficulty larger, the present invention, in the form of hydraulic bag, the foot mechanical movement of vertical direction is converted in pipeline The kinetic energy of the liquid being easy to collect of middle flowing, transformation efficiency is high, can make full use of the energy that human body tramples generation.Hydraulic bag 13 Optional elastomeric material, it possesses certain elasticity and intensity, waterproof, cheap, and sole environment will not be subject to sunlight Irradiate and corrosiveness, less demanding to corrosion resistance.The feature that can be advanced according to human body, hydraulic bag 13 is designed as ellipse Circle, is easy to liquid flowing under extrusion, improves liquid flow rate, and then improve generating efficiency.

In order to improve the outlet kinetic energy of liquid, hydraulic bag outlet extending forms the flexible pipe with certain length, flexible pipe 12 Diameter and motor inlet diameter matches, water conservancy diversion can be played and improve the effect of liquid rate, in the effect of identical extruding force Under, the kinetic energy of liquid increases, and then can be with improve generating efficiency.

In human body traveling process, two hydraulic bags are alternately extruded, and the liquid in hydraulic bag is continuous under the driving of external force Ground extrusion and flowing back to, and conventionally used fluid generator is unidirectional, for this reciprocating liquid energy utilized relatively Little, generating efficiency is relatively low.So for less apparatus of the present invention for system scale, selection one kind can be at two The structure of the kinetic energy using fluid is come with higher efficiency on direction, as much as possible improve generator coil group in magnetic flux and The flux change rate in coil group in motor process, for improving, generated output is particularly significant with generating efficiency.Again due to this Small generator is installed in sole, can bear certain pressure, and be provided with impeller, line inside it during normal work The parts such as circle, magnet, brush, so need shell mechanism to protect the part of inside with enough intensity.The impeller of electromotor Need to be operated in liquid environment, so the electromotor in TRT of the present invention is inside and outside double-layer structure.The two ends of shell body 1 It is connected with the exit seal of 2 hydraulic bags 13；Inner housing 2 is fixedly mounted on the inside of shell body 1；Shell body 1 and inner housing 2 it Between for liquid path；2 impellers 7 are reversibly mounted on the two ends of inner housing 2, the liquid between shell body 1 and inner housing 2 In path, for liquid kinetic energy being converted into the rotation momentum of impeller；Magnet group 3 and coil group 4 are arranged on the interior of inner housing 2 Portion, and the impeller axle 5,6 respectively at 2 impellers 7 is fixedly connected, is being subject to when the impacting of liquid from any one end, two The contrary impeller 7 installed can rotate, all the time in the opposite direction thus driving magnet group 3 and coil group 4 to revolve in a reverse direction Turn.With respect to the stator rotor structure of conventional electric generators, dual-rotor structure can further improve magnet group and coil group it Between relative motion, also can better profit from simultaneously in human body traveling process to 2 hydraulic bags replace extrude, liquid bidirectional flow Feature, thus improving the flux change rate in coil, improve generating efficiency.

Wherein, shell body 1 acts primarily as the function of protection inner member and structure, needs that intensity is larger to prevent that tramples to rush The power of hitting acts on the part within electrification structure, and because shell will be arranged in footwear, so the weight of crust of the device is unsuitable Overweight impact human motion, and have the presence of water in working environment, so material must be by aqueous corrosion, and shell body 1 Can not be conductive, therefore, shell body 1 should be made, lightweight electrically non-conductive material high by a kind of intensity, such as rigid plastics.

Shell body also will undertake simultaneously and connect to introduce the function of liquid, shell body 1 rear and front end and liquid with hydraulic bag 13 The part that pressure capsule 13 connects is carved with screw thread to seal, and, is provided with water in-out port on the end face of shell body 1 rear and front end 19, as shown in figure 4, water in-out port 19 is symmetrical circular arc, be conducive to, by the blade of liquid guide flow to impeller 7, reducing energy Amount loss.

Additionally, shell body 1 also will possess the function of the electric energy output producing electromotor, if using wire from shell Draw, the liquid between shell body and inner housing is easy to reveal, so using output electrode as outwardly exporting electric energy Interface, the middle part of the shell body 1 sharing with shell body 1 in inner housing 2 be respectively provided on two sides with output electrode 9, wherein, can adopt The preferable copper sheet of conductivity is as output electrode.

Inner housing 2 is airtight cavity, is become by the vertical intersecting shape of two cylindrical housings, is fixedly mounted on shell body 1 Inside, is fixedly mounted on the inside of shell body 1, and is intersected with the middle part of shell body 1, in shell body 1 common enclosure body 1 Portion, as shown in Figure 3.The function of inner housing 2 is the protection part such as its internal coil group, magnet group, inner housing 2 and shell body 1 Between space be liquid flow passage.It is installed with bearing, magnet group 3 and coil group 4 are fixed respectively inside inner housing 2 It is arranged on inner bearing and outer bearing；The intersection with shell body 1 for the inner housing 2 arranges output electrode 9.According to shell body The analysis of 1 material, the material of inner housing 2 can be identical with shell body 1 material.

Impeller 7 is the device of the mechanical energy that the kinetic energy of liquid is converted to rotation.In order to realize two-way generating, by 2 leaves Wheel 7 is reversibly mounted on the two ends of electromotor internal layer shell 2.The axle (impeller axle 6) of 2 impellers 7 respectively be arranged in inner housing 2 The magnet group 3 in portion is fixedly connected with coil group 4.When the liquid entering from any side impacts the impeller at two ends successively, two Impeller starts to rotate in a reverse direction, drives magnet group and coil group to rotate in the opposite direction respectively, produces electric energy.Impeller Same using rigid plastics i.e. can be relatively low cost preferably complete function.

The Magnet of magnet group 3 is the source producing magnetic flux, and the magnetic force of Magnet is stronger, then the rate of change of magnetic flux is bigger； Meanwhile, magnet volume is smaller, so could form array and put in footwear.Current ferromagnetic material mainly has ferrite, neodymium Ferrum boron, SmCo and aluminum nickel cobalt.Wherein ferritic performance low and in, price is minimum, and temperature characterisitic is good, corrosion-resistant, performance and price Than good；Neodymium iron boron performance highest, in price, intensity is good, non-refractory and corrosion；The performance of SmCo is high, and price highest is crisp, temperature Degree characteristic is excellent, corrosion-resistant；Aluminum nickel cobalt performance is low, and in price, temperature characterisitic is excellent, and corrosion-resistant, resistance to interference is poor.In view of in footwear Application, to temperature performance and decay resistance not very high requirement, and require better performances, therefore select neodymium iron boron this The Magnet of one material.

Because coil group and magnet group are rotor, the multiphase electric energy that the magnet coil structure of multipole multiphase produces needs phase Electric energy is spread out of by the brush structure answered, and does brush material with copper sheet and can preferably complete this function.As shown in figure 3, connecting The both sides of the impeller axle 6 of coil group 4 are provided with brush 8, and brush 8 is connected with output electrode 9, and magnet group 4 and coil group 5 rotate and produce Alternating current by brush 8 export to send out an output electrode 9, thus electric energy is exported.
