6. the carry-on vehicle of folding electric according to claim 1, it is characterised in that: inlay one piece at the concave arc of unilateral rear fork Centre opens up the surface plate of slot, and as the main radiator of controller power valve, unilateral rear fork is for the cover board of slot Power tube auxiliary heat dissipation, power tube are fixed on the cover board of slot, and the pin of power tube is arranged with flexible cord to be connect with circuit board, Circuit board and cable connector are placed in the pipe of unilateral rear fork, the cover board of slot in a manner of ring flange with unilateral rear fork Docking.

7. the carry-on vehicle of folding electric according to claim 1, it is characterised in that: the foldable pipe horizontal intermediate fixed section Interior installing tension spring and lock, the pipe both ends inner wall of intermediate fixed section respectively open up two slideways, the pipe left and right ends of intermediate fixed section Lower section opens up notch, and left and right two folds the pivot pin component installed in arm ends, and the pipe inner slide for being inserted into intermediate fixed section can be certainly By sliding, by the tension spring inside intermediate fixed section pipe and the foldable automatically lock horizontal flattening and folded state of completion is latched, Handle is accelerated to use sectional design, Hall subassembly is individually placed in a small circle ring integrally formed with digital displaying meter, roundlet Ring, which is inserted into, to be folded on arm, magnetic induction device built in the part that turning handle is bonded with small circle ring, and turning handle inner sleeve, which is fixed on, to be folded on arm, is turned Handle housing and turning handle inner sleeve are rotatablely connected, and the reset scroll spring of turning handle housing is installed in the pipe for folding arm, mechanical brake system The brake cable of system is placed in arc back rest pipe, arc main-beam pipe and handlebar and stands in the auxiliary pipe in side, and horizontal place is only drawn close to foldable The interior lines of brake cable are to brake lever out.

8. the carry-on vehicle of folding electric according to claim 1, it is characterised in that: tow holding and be fixed on seat support and subtract It shakes between spring, seat is fixed on arc seat pipe upper end by seat support, the total unlock dress of installation in the upper end of arc seat pipe It sets, is connect respectively with the lock pin of the lock pin of folding locking mechanism and expansion retaining mechanism by stone dead wire.

9. the carry-on vehicle of folding electric according to claim 1, it is characterised in that: when folding, by a foldable left side on horizontal Right two foldings arms simultaneously pull open and be folded down, then dextrorotation steering pivot pin to 180 ° limits vertical parallel with handlebar to the left and right by two sides Fixture block, due to turning to the vertical middle separated time of pivot pin to the vertical middle separated time right side offset of foldable chassis, the distance of offset is wheel Total tripper in arc seat pipe upper end is pressed so that front-wheel has been displaced the width of a tire to the right in the 1/2 of tire width Release lever, pull out expansion retaining mechanism lock pin so that arc seat pipe is separated with arc back rest pipe, while being lifted up and dragging Row is held, since maincenter folds inside assembly, in the synchronization teeth and arc back rest pipe on U-shaped connector in arc seat pipe Synchronization teeth on U-shaped connector are meshed, so that rear-wheel rolls forward, seat closes up to foldable horizontal, the arc back rest Pipe is synchronized to arc main-beam pipe to be closed up, seat and it is foldable cross sticker is closed after, arc back rest pipe and arc main-beam pipe are also synchronous to be pasted Unify, the folding locking mechanism automatic locking between arc main-beam pipe and arc back rest pipe, so that front-wheel and rear-wheel are in left and right Parallel alignment state, so that vehicle shows tiny square tube shape, convenient for towing with oneself and carrying, by rolling on unilateral front fork Folded vehicle ladder is folded down exhibition and directly supports ground together with the main vehicle ladder on unilateral rear fork, and upright posture is just presented in vehicle, places corner not Land occupation side.

10. the carry-on vehicle of folding electric according to claim 1, it is characterised in that: when expansion, press arc seat pipe upper end The release lever of interior total tripper, pulls out the lock pin of folding locking mechanism, so that arc main-beam pipe is separated with arc back rest pipe, It gently mentions and tows holdings, left-handed 180 ° of steering pivot pin, the spring of the Foldable car ladder tripper on unilateral front fork discharges, and pull-out can Folded bicycle ladder opens up the lock pin of straight retaining mechanism, and Foldable car ladder is packed up automatically, and downward push tows holding, since maincenter folds always At inside, synchronization teeth on U-shaped connector in arc seat pipe and the synchronous teeth on the U-shaped connector on arc back rest pipe Be meshed so that rear-wheel rolls backward, so that arc seat pipe and arc back rest pipe synchronous reset, arc seat pipe and the arc back rest The foldable folding arm of left and right two on horizontal is folded up by the expansion retaining mechanism automatic locking between pipe, fold arm from Dynamic to reset foldable cross of flattening, vehicle restores unfolded state.
