Using above scheme, the output shaft and rotor assembly of the Power Component are coaxially disposed, and are directly protruding into stator It connect in component, three are combined into one with rotor assembly, in the colleague of the power demand of guarantee normal power generation, not only structure is more Add simple and compact, and volume is smaller.

As shown, the Power Component 30 is fixed including cylinder block 1,2, two groups of flappers 6 of output shaft and two groups Baffle 7, the flapper 6 are arranged in cylinder block 1 with fixed baffle 7 and are formed 4 sealing cavities, and the flapper 6 can be provided with air inlet 3, gas outlet 4, igniter 5 on 1 center reciprocating rotation of cylinder block, the cylinder block 1, it is described into Port 3, gas outlet 4, igniter 5 are at least provided with 2, and corresponding with each sealing cavity respectively, 4 sealing cavities Four air inlet, compression, igniting and exhaust impulse strokes, the company of transmission between the flapper 6 and output shaft 2 are respectively corresponded again It connects.

In addition, the igniter 5 can be atomizer, it is also possible to spark plug.

The fixed baffle 7 is structure as a whole with cylinder block 1, and air inlet 3, gas outlet 4, the setting of igniter 5 are solid Determine in baffle 7.

Its working principle is as shown, cylinder block 1 is divided into tetra- sealings skies of A, B, C, D by flapper 6 and fixed baffle 7 Chamber, work are made of four air inlet, compression, igniting and exhaust impulse strokes.It is recycled by first job of the upper left corner Fig. 2, Sealing cavity A air inlet, sealing cavity B are compressed, and sealing cavity C igniting expansion, sealing cavity D exhaust drives flapper 6 Rotationally clockwise；When first job circulation terminates to enter second working cycles, then sealing cavity D air inlet, sealing sky Chamber A is compressed, and sealing cavity B igniting expansion, sealing cavity C exhaust drives flapper 6 to rotate counterclockwise；When second Working cycles terminate to enter third working cycles, then sealing cavity C air inlet, and sealing cavity D is compressed, sealing cavity A point Fire expansion, sealing cavity B exhaust, drives flapper 6 to rotate clockwise；When third working cycles terminate to enter the 4th work It recycles, then sealing cavity B air inlet, sealing cavity C is compressed, and sealing cavity D igniting expansion, sealing cavity A exhaust drives Flapper 6 rotates counterclockwise；When the 4th working cycles terminate to reenter first job circulation.

Such four partial circulatings form a systemic circulation, constantly push 6 reciprocating rotation of flapper, flapper 6 is then 2 synchronous rotary of output shaft is driven, output shaft 2 then drives rotor assembly to rotate, and cutting magnetic line makes to generate induced potential It obtains rotor assembly and stator module cooperation generates electricity.

Through the above scheme, compression ratio in its cylinder can not only preferably be adjusted, energy consumption is lower, while flapper is subject to Active force is big with reaction force, and power is more sufficient.

As shown, the cylinder block 1 includes cylinder body 11 open at one end, 11 center of cylinder body is fixedly installed positioning Axis 12, one end that the cylinder body 11 is open is rotatably provided disk 13, and the disk 13 and the sealing of cylinder body 11 cooperate；Institute It states flapper 6 to be fixed on the end face of disk 13, and protrudes into cylinder body 11 and match with 11 inner wall of cylinder body, the sealing of 12 outer wall of locating shaft It closes；The fixed baffle 7 is fixed in cylinder body 11, and is cooperated with 11 inner wall of cylinder body, the sealing of 12 outer wall of locating shaft.

Wherein, the output shaft 2, which can be, is directly fixedly connected with the center of disk 13, can also by transmission mechanism with Disk 13 realizes transmission connection, such as V belt translation, gear drive.

As shown, further including having starter, the starter includes starter motor 9, crank and rocker mechanism 8, is subtracted Fast machine, clutch, the starter motor 9 are connected with speed reducer by clutch, and the crank and rocker mechanism 8 includes a company Bar, described connecting rod one end and disk 13 are hinged, and the rotation center eccentric setting at its hinged center and disk 13, the other end with subtract The output end of fast machine is hinged, and the rotation center eccentric setting of the output end of its hinged center and speed reducer.

Wherein, short connecting rod can be set between the output end of connecting rod 8 and disk 13, speed reducer, by short connecting rod come Realize its necessary eccentric distance.

When starting to work, for starter motor through clutch structure in conjunction with speed reducer, speed reducer passes through crank and rocker mechanism 8 It drives disk 13 to rotate, when disk 13 then drives flapper to turn to designated position, just starts igniting workmanship at this time, realize dynamic The movement of power component, while clutch also will disconnect starter motor.

Triggering sensing device is additionally provided on the flapper, triggering sensing device is for controlling air inlet 3, gas outlet 4 With igniter 5, when flapper is rotated to designated position, triggering sensing device will issue signal, control it is specified into Port 3, gas outlet 4 and igniter 5 work, to ensure engine normal operation.

By taking the first job in the upper left corner Fig. 3 circulation as an example, flapper 2 is in starter motor or the working cycles of previous step Drive under, reach position in figure, at this point, triggering sensing device issues signal, the air inlet open of corresponding sealing cavity A, together When its gas outlet close and igniter do not work, to realize air inlet；Air inlet, the gas outlet Jun Chu of corresponding sealing cavity B In closed state, and igniter does not work, to realize compression；The air inlet of corresponding sealing cavity C, gas outlet are in pass Closed state, control igniter work igniting expansion；The gas outlet of corresponding sealing cavity D is opened, inlet close and igniting dress It sets and does not work, to realize exhaust.

Wherein, the mode that position signal detection can be used in triggering sensing device carries out, and may also set up the knot of at least three cam Structure is realized by cam contact control switch and is controlled.

Certainly, above-mentioned starter and triggering sensing device are conventional design in available engine, therefore to its structure It is not described in detail, only does principles and methods herein, to be best understood from the working principle of the present embodiment.

In addition, the cylinder block 1 is equipped with multiple groups and is stacked, flapper 6 is correspondingly arranged in every group of cylinder block 1 With fixed baffle 7；The output shaft 2 is arranged one, and the flapper 6 in each cylinder block 1 is connected by transmission mechanism same One output shaft 2.

The layout type being superimposed by multiple groups, not only power is more sufficient, but also ensures its operation is stable, will not stop working.
