Description
Technical field
The utility model relates to a kind of Electrical Bicycle, particularly a kind of folding electric bicycle.
Background technology
Existing folding electric bicycle generally adopts the mode of front and back wheel doubling, can not move after folding, can only guide and support, and is very inconvenient, existing folding electric bicycle complex structure simultaneously, complex operation.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of folding convenient is provided, the Electrical Bicycle that can carry out after folding.
The technical scheme that realizes the utility model purpose is, folding electric bicycle, comprise front and back wheel, the handlebar tube that is connected with front-wheel, the upright fork and the chain stay that are connected with trailing wheel, with the seat pipe, the transverse tube that handlebar tube is connected, be located at the wheel hub motor of trailing wheel, and be located at battery and controller on the handlebar tube, it is characterized in that, the tail support that the tail end of described transverse tube is provided with, tail support are by two sides and the flute profile that the bottom surface surrounds, and the bottom of described seat pipe is located in the tail support, with two rotatable connections of side of tail support, two rotatable connections of side of described upright fork and tail support; Between transverse tube and chain stay, be provided with support tube, the two ends of support tube respectively with transverse tube, chain stay is rotatable is connected; Be provided with connecting rod between support tube and the seat pipe, the rotatable connection managed with support tube, seat respectively in the two ends of connecting rod.
Transverse tube of the present utility model flute profile tail support is set, seat pipe and upright fork all with rotatable connection of flute profile tail support, chain stay is connected by support tube and transverse tube are rotatable, connecting rod plays the interlock effect in expansion and folding process.When folding, the seat pipe is to the transverse tube rotary folding, and chain stay and upright fork are being with trailing wheel to rotate forward, near front-wheel, dwindle the distance between the front and back wheel.After folding, front-wheel is parallel with trailing wheel, and front-wheel and trailing wheel can roll, and bicycle can also be carried out.
As further improvement of the utility model, also be provided with crank between present pipe and the transverse tube, the two ends of crank are connected with seat pipe and transverse tube are rotatable respectively, between the song point of both sides crank handle are set, and conveniently pull folding operation.
As further improvement of the utility model, be provided with the plastics trustship in the groove of flute profile tail support, the lower end of seat pipe is located in the plastics trustship, opens the support of state in car exhibition as the seat pipe, prevent that the pipe from dawdling with flute profile tail support in folding, the heavy burden of being born for the seat pipe simultaneously cushions.
As further improvement of the utility model, described battery adopts lithium electricity battery, preferably adopts the dynamic lithium battery that Electrical Bicycle is used of specializing in of Korea S SK company, and this battery volume is little, in light weight, is 1/3 of common lead-acid battery, is easy to carry; Life-span is long, be common lead-acid battery life-span 2-3 doubly.
As further improvement of the utility model, described wheel hub motor adopts brushless motor, and volume is little, and is in light weight, and the efficient height meets the purpose that folded bicycle is convenient for carrying.
As further improvement of the utility model, have Intelligent Power Module in the described controller, realize smoothly adjustable-speed.

Fig. 3 is the utility model embodiment 1 folding electric bicycle folded state scheme drawing
The specific embodiment
Be described further below in conjunction with embodiment.
As shown in Figure 1, folding electric bicycle 1, comprise front-wheel 2, trailing wheel 3, the handlebar tube 8 that is connected with front-wheel, the upright fork 4 that is connected with trailing wheel and chain stay 5, the transverse tube 7 that is connected with seat pipe 6, handlebar tube 8 is located at the wheel hub motor 9 of trailing wheel, and is located at battery and controller 10 on the handlebar tube, the tail support 11 that the tail end of transverse tube 7 is provided with, tail support 11 is by two sides 12 and the flute profile that bottom surface 13 surrounds.The bottom of seat pipe 6 is located in the tail support, and is hinged with two sides 12 of tail support 11.Upright fork 4 is articulated in the D point with two sides of tail support 11.Be provided with support tube 14 between transverse tube 7 and chain stay 5, an end of support tube 14 and transverse tube 7 are articulated in the B point, and the other end and chain stay are articulated in the E point.Be provided with connecting rod 15 between support tube and the seat pipe, an end of connecting rod 15 and support tube 14 are articulated in the F point, are articulated in the G point with seat pipe 6.Also be hinged with crank 16 between the H point on present pipe G point and the transverse tube, between the song point N of two cranks 16 of both sides the handle (not shown) is set, when folding, except can be by the wedge pipe, take to draw the mode of the handle of crank 16 to drive the rotation of seat pipe, more convenient like this folding operation.
Be provided with the plastics trustship in the groove of flute profile tail support, the lower end of seat pipe 6 is located in the plastics trustship.
Battery adopts the dynamic lithium battery that Electrical Bicycle is used of specializing in of Korea S SK company, and wheel hub motor adopts brushless motor.Have Intelligent Power Module in the controller, realize smoothly adjustable-speed.
As Fig. 2 and Fig. 3, when folding, the handle of mentioning crank 16, with the downward forward application of force after the saddle counter-rotating, driving the four-bar linkage of being made up of support tube 14, chain stay 5, upright fork 4 and transverse tube 7 by connecting rod 15 pulls forward, it is close to front-wheel simultaneously also to drive trailing wheel, hinge-point E is progressively to rotating around hinge-point B, when BEF is the dead point in line, continue the downward application of force, side triangle DOE becomes anti-triangle DOE, and this moment, four connecting rod vehicle frames formed self-locking state, when upwards guiding and supporting saddle, trailing wheel can thereby not fall because of the former of gravity.
