Beneficial effect of the present invention is: (1), when normally running, lithium cell is powered to drive motor, and drive motor drives Electrical Bicycle to run; When riding, signal is provided when speed sensor monitors and arrives setting speed from fluted disc group velocity of rotation, controller starts drive motor and brings into operation, for power-assisted of riding, controller starts drive motor and brings into operation, and is power-assisted of riding, alleviates the burden of riding of bicyclist, the now operation of drive motor needs a small amount of electricity, thus it is farther to realize the operating range of Electrical Bicycle under equal electricity; (2), when depositing, by folder by front and rear sections doubling, making Electrical Bicycle compacter, being easy to carry.
In the present invention, described lower pipe is provided with luminary, when Electrical Bicycle is exercised, particularly can play the effect thrown light on and warn other vehicles and note when night exercises.
In the present invention, under the bottom of described vehicle frame back segment and back segment, connecting-reinforcing beams between pipe, manages under described back segment, forms gusseted between vehicle frame back segment and strength beam, thus improves the intensity of Electrical Bicycle further.
In the present invention, between described front section of vehicle frame and handrail, between vehicle frame back segment and vehicle seat, be equipped with arrangement for adjusting height, to meet the needs of riding of different crowd.
Accompanying drawing explanation
Fig. 1 is the structural representation of folding electric bicycle of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, further description is answered to the present invention.
As shown in Figure 1, folding electric bicycle of the present invention, comprises vehicle frame, comprises front section of vehicle frame 2, vehicle frame back segment 1, front vehicle wheel 8, rear wheel 9, vehicle seat 6, handlebar 5.Be connected lower pipe between front section of vehicle frame 2 with vehicle frame back segment 1, lower pipe to comprise under leading portion pipe 4 under pipe 3 and back segment, is connected under leading portion under pipe 3 and back segment between pipe 4 by folder 7.Rear wheel 9, vehicle seat 6 and rear clothes hanger 14 are arranged on vehicle frame back segment 1, rear wheel 9 and drive motor 16 and flywheel 11 combined.
Vehicle seat 6 is provided with control apparatus 15 with the junction of vehicle frame back segment 1, and control apparatus 15 can regulate the height of vehicle seat 6.Front-wheel 8 is arranged on front fork, front fork is arranged in the head tube of front section of vehicle frame 2, handlebar 5 is arranged in front section of vehicle frame 2 head tube in standpipe of front fork, and handlebar 5 and front section of vehicle frame 2, junction, standpipe of front fork place are provided with control apparatus 17, and control apparatus 17 can regulate the height of handlebar 5.
Under leading portion under the rear end of pipe 3 and back segment pipe 4 front end between attachment folder 7, pipe 4 under pipe under leading portion 3 and back segment can fold by folder 7 mutually.Form straight line when pipe 4 is folding under pipe 3 and back segment under leading portion, under leading portion, the front end of pipe 3 is higher than the rear end of pipe under back segment 4, and the straight line that under leading portion, under pipe 3 and back segment, pipe 4 is formed and ground are 10-45 degree left and right angle.Under leading portion, the front end of pipe 3 is fixedly connected with the head tube of front section of vehicle frame 2, and under back segment, the rear end of pipe 4 is fixedly connected with vehicle frame back segment 1.Under leading portion, under pipe 3 and back segment, pipe 4 all uses hollow structure, installs lithium cell, mount controller in pipe 4 under back segment under leading portion in pipe 3.Be provided with set copper contact bottom the lithium cell installed in pipe 3 under leading portion, under back segment, the front end of pipe 4 is provided with convex copper contact, when pipe 4 under pipe under front section of vehicle frame 3, back segment after merging concavo-convex copper contact automatically closely close up contact, power connection; When in pipe 4 under the battery bottom in pipe 3 under leading portion after folding and back segment, two concavo-convex contacts disconnect automatically, stop power supply.Under leading portion pipe 3 outer wall on be interval with multiple LED illuminator 17, for Electrical Bicycle use provide illumination with warning.
Connecting-reinforcing beams 18 between pipe 4 under the bottom of vehicle frame back segment 1 and back segment, forms gusseted between pipe 4 and vehicle frame back segment 1, strength beam 18 under back segment, improves the intensity of Electrical Bicycle.Vehicle frame back segment 1 lower end five-way installs fluted disc group 10, and foot-operated 13 are arranged on the crank of fluted disc group 10, by chain 12 transmission between crank group 10 and flywheel 11, steps on foot-operated 13 flywheel drivens 11 rotations and can realize Electrical Bicycle and ride.Be provided with speed sensor outside fluted disc group 10, speed sensor is fixedly mounted on the axle of the crank of fluted disc group 10, and the signal wire (SW) of speed sensor is connected with controller.
When normally running, lithium cell is powered to drive motor, and drive motor drives Electrical Bicycle to run; When the personnel of riding step on pin step on by fluted disc group drive chain flywheel turns can realize Electrical Bicycle run time, when fluted disc group velocity of rotation reaches the speed of setting, speed sensor by fluted disc group velocity of rotation signal feedback to controller, controller starts drive motor and slowly runs, for personnel's power-assisted of riding, while alleviating the burden of riding of bicyclist, improve the running velocity of Electrical Bicycle.The now operation of drive motor only needs to expend a small amount of electricity, thus it is farther to realize the operating range of Electrical Bicycle under equal electricity.
By the actual detection of riding of bicyclist, specification is adopted to be 24V, 8.5Ah, during the lithium cell group of size 403*85*40mm, can effectively use about 3 years, the number of times of discharge and recharge can be provided to reach more than 1000 times, once charging is omnidistance when adopting drive motor to drive, and its effective milimeter number reaches 40 kilometers, and when omnidistance drive motor drives auxiliary foot-operated band active toothed disk group of riding simultaneously to rotate power-assisted, its effective milimeter number can reach 55-60 kilometer, greatly can improve the flying power of Electrical Bicycle with this as seen.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
