The side arm 15 founds 152, foldable handlebar 153, front fork and wheel 154 including arc channel bar 14, wheel pipe 151, folded tube, preceding Fork and wheel 154 are rotatablely connected with slide block wheel pipe 151, the folded tube vertical 152 of front fork upper end connect band foldable handlebar 153, the arc Channel bar rear end is fixedly connected with the front ends Di Gang, certainly, can also upwarp the front ends Di Gang and is directly fixedly connected with wheel pipe.

As shown in Fig. 2 Fig. 4 Fig. 6, the pivoted frame 13 is fixed on the rear end of bottom thick stick vertically, and structure is solid between upper and lower cross bar A fixed connection at least montant, montant length are more than the height of side frame 2, are fixedly connected between upper and lower cross bar two ends vertical Bull stick 131, bull stick is circular pin or bar is equipped with hinge 311, and tube 26 vertical with side frame or hinge are rotatablely connected, after pivoted frame It holds and is equipped with gear frame 132 on the inside of bull stick, for keeping out postrotational side frame outer plate surface, keep side frame parallel with bottom thick stick, keep off frame and side frame Corresponding position is respectively equipped with holding firmware 27, for fixing postrotational side frame 2.

As shown in Figure 4 and 1,13 bottom end stage casing of the pivoted frame is fixedly connected with bottom thick stick 11, and shape is plugged in the thick stick nozzle of bottom The cross bar both ends of the corresponding flexible kelly 12 of size, bar Xiang Duan are equipped with holding firmware 27, can be with postrotational side frame outside plate 24 Lateral 25 grafting of card slot, kelly retract in pipe or with postrotational side frame grafting, effect is after rotate to being attached to gear frame The side frame fixing in outside is integral, and kelly is shorter than the length of side frame.

As shown in Fig. 3 Fig. 4, the kelly upper end position of pivoted frame is rotatably connected to driving part box 31, electric drive is placed in box Component battery, the controller of system 3, box body are placed vertically in gear frame or are flat on the flexible kelly fixed with side frame vertically, when So, box body can also horizontal directly with both sides outer frame board card piece 27 fix, center of gravity is low when driving for such construction vehicle, stablize peace Entirely.

The body frame bottom end is equipped with supporting leg 16, and vehicle seat folding is placed on the upper ends Di Gang, and when not using seat cover mode, body frame is another If kelly 12, for fixing the side frame for folding or being unfolded.

2, side frame.

As shown in Figure 4 and 1, the side frame 2 includes framework, trailing wheel 23, and side frame is located at the both sides of body frame, rectangular, is two Short tube is equipped between the single frame that a parallel and montant, cross bar both ends are fixedly connected, stub length is more than installed trailing wheel Thickness, the side frame length are more than wheel diameter, are highly more than the radius of trailing wheel, axillare is fixedly connected among two bottom bar of frame lower end 22, rotational installation trailing wheel 23 or the side frame lower end are the parallel double slide bars 21 being fixedly connected, two pieces of sliding axles between two axillares Plate 22 is equipped with the horizontal casing that silk is twisted with hand above and below, and sliding sleeve is through on the parallel double slide bars 21 in side frame bottom end and fixes, sliding Moving axis plate is connect with rear wheel, and the forward lower comer of such structure side frame does not set short tube, trailing wheel can forward end sliding fix, make With being the distance for pulling open front and rear wheel, convenient for riding.

Side frame outside plate lower end is equipped with horizontal card slot 25, the bottom thick stick inner telescoping tube kelly of card slot and corresponding position after side frame rotation 12 clampings, side frame outside plate upper end are equipped with vertical card slot, are fixed with the fastener 12 separately set.

It is equipped with the vertical tube 26 being fixedly connected on the outside of side frame rear end, rotates socket with pivoted frame bull stick 131 or side frame passes through Hinge is connect with bar rotation, and position of such structure for side frame is converted, and side frame folding is built in the both sides Di Gang, or revolves backward Turnback is placed in pivoted frame rear end and is fixed with gear frame 132, simultaneously as side frame is rotated by the center of circle of rear end exterior angle tube, rotation Become inside on the outside of rear side frame, two trailing wheel spacing, forward and backward tyre tread pull open simultaneously, are conducive to car body and stablize.

Illustrate herein, side frame is using the state folded as orientation standard, and one end with tube 26 is rear end, with card slot 25 Outside plate is outside, does not change orientation standard after rotation.

As shown in Fig. 6 Fig. 8, seat cover 18 is rectangular, is interior box-like, cavity and folding for cavity and rear end, bottom opening Body shapes afterwards are corresponding, and it is elastic cushion to sit cover top surface, sit cover both sides and are equipped with and side frame outside plate card slot, driving part box phase Corresponding fastener is sat on the car body of cover the cover after folding, or is connected between postrotational two side frame.

Two, operation principle.

As shown in Figures 1 to 8, folding electric-tricycle operation principle is as follows.

1, folded state.

The pedal of bottom thick stick is holded up, and side frame is adjacent to the storing of the both sides Di Gang, and vehicle seat folding collapses in the space between side frame, preceding The sliding block of frame moves to the fixing of arc channel bar top, and analysis of wheel vertical is flat on behind ground, the vertical folding of handlebar, pipe in two side frame upper ends Between, fix kelly；When using sitting cover mode, it will directly sit on the car body of the cover after folding and fixing；Volume is most compact in this way.

Supporting leg is packed up when carrying, when front-wheel is horizontal, only need to be dragged folded bicycle front end drawbar, be slided by trailing wheel.Or front-wheel When longitudinal storing, if front-wheel drive, walking of driving directly is sitting on cover, and such as rear wheel drive mode, handlebar adds band and moves backward The controller of switch, riding over can walk on folded bicycle.

2, unfolded state.

Supporting leg is propped, trailing wheel is hanging, above carries fastener or sits cover and puts on one side, and side arm handlebar is propped, and folded tube is vertical to be fixed vertically, Side frame back rotation 180 degree is placed on rear side of pivoted frame and is adjacent to fixing with gear frame, by the card at the flexible kelly cross bar both ends in the thick stick pipe of bottom Part is directed at the horizontal card slot of side frame outside plate lower end, and kelly is moved to suitable position and fixes, by vertical driving part box it is horizontal It on flexible kelly or fixes between two side frames, then will sit between cover card is placed on two side frames, or the vehicle use of revenue to finance expense of folding is risen, then will Sliding block movement with side arm rotation connection is fixed in arc channel bar appropriate location, so that side arm is formed certain angle with ground, is packed up branch Leg, trailing wheel land, and can ride.

When using trailing wheel sliding axle harden structure, trailing wheel fixing can be adjusted backward, can increase the spacing of front and rear wheel, with Ensure that car body is stablized.

All any modification, equivalent replacement, improvement on the basis of pressing the utility model embodiment, should be included in this reality Within the scope of novel protected.
