Abstract

The utility model relates to a belt pulley unit of an electric bicycle. A belt pulley transmission mechanism is arranged in a proper position of a rear wheel of the bicycle. The utility model is characterized in that the belt pulley transmission mechanism is provided with a belt gear at the center of the rear wheel by utilizing a side edge which is formed by connecting a center pipe, a bearing and a one-way rotating flywheel, and the belt gear is hooped with a tooth-shaped belt of which the other end is hooped with a shaft center gear of a motor. Therefore, a battery can provide a power supply to drive the motor so that the tooth-shaped belt can be driven to rotate, and therefore, the rear wheel can rotate to drive the electric bicycle to run forwards.

Description

The Electrical Bicycle pulley apparatus

The utility model system is relevant with electric bicycle structure, more detailed it, refer to especially that a kind of assembling is convenient and it is simple and easy to operate and can protect the Electrical Bicycle pulley apparatus of CD-ROM drive motor.Belong to the Electrical Bicycle accessory.

At present, Regular Bicycle is all based on foot-operated, that is be purpose mostly with the bodybuilding and entertainment, if desire to ride instead of walk and may all can replace it with motor bike, but if use motor bike not only can cause aerial contamination, and more can waste natural resources, therefore a kind of Electrical Bicycle appears in the market at present, but have both the function of motor bike and bicycle, yet though this kind structure can be improved above-mentioned drawback, precisely because a defect when implementing, occurs, that is, this CD-ROM drive motor also still continues to drive when car body stops, especially when retreating, just can be with commentaries on classics firmly by belt pulley, so that can cause motor overheated and damage.

Main purpose of the present utility model is: a kind of Electrical Bicycle pulley apparatus is provided, and its assembling is convenient and transmission is smooth and easy, and can improve the value of industrial community utilization, makes it to have more economic benefit.

A kind of Electrical Bicycle pulley apparatus of the utility model, its appropriate position that ties up to this bicycle rear wheel is provided with a pulley transmission mechanism, it is characterized in that: this pulley transmission mechanism ties up to center mat one base pipe of rear wheel and a bearing and the unidirectional commentaries on classics flywheel side that is connected one belt gear is set, and at belt gear upper ring hoop one dentation belt, this dentation belt end in addition then encloses hoop one axle center of motor gear, by this, give CD-ROM drive motor by a storage battery supply power, rotate and drive the dentation belt, activation is advanced rear wheel rotating drive Electrical Bicycle.

The utility model has the advantages that:

1, easy to operate, safety performance is good, uses reliable and stable.

2, easy to assembly and convenient rapidly.

3, start is smooth and easy, controls freely.

4, can protect driver element not damage, long service life safeguards that easily wide market outlook are arranged.

The utlity model has following accompanying drawing:

Fig. 1 is the three-dimensional exploded view of the utility model.

Fig. 2 is the combination scheme drawing of the utility model.

Fig. 3 is the enforcement scheme drawing of the utility model.

Fig. 4 is the enforcement scheme drawing of the utility model.

Fig. 5 is the enforcement scheme drawing of the utility model.

Number in the figure is as follows:

10. rear wheel 20. pulley transmission mechanisms 21. base pipes

22. bearing 23. flywheels 24. belt gears

25. dentation belt 26. axle center gears 27. storage batterys

28. motor 30. Electrical Bicycles

Now lift preferred embodiment and conjunction with figs. is described as follows:

At first, see also Figure 1 and Figure 2, a kind of Electrical Bicycle pulley apparatus of the utility model, its appropriate position that ties up to this Electrical Bicycle (not shown) rear wheel 10 is provided with a pulley transmission mechanism 20, it is characterized in that:

This pulley transmission mechanism 20 ties up to center mat one base pipe 21 of rear wheel 10 and a bearing 22 and a unidirectional commentaries on classics flywheel 23 side that is connected one belt gear 24 is set, and at belt gear 24 upper ring hoops one dentation belt 25, this dentation belt 25 end in addition then encloses hoop one axle center of motor gear 26, by this, by a storage battery 27 supply power CD-ROM drive motor 28, rotate and drive dentation belt 25, activation is advanced rear wheel 10 rotating drive Electrical Bicycles.

When assembling, please continue to consult Figure 1 and Figure 2, at first, this rear wheel 10 is to establish this bearing 22 prior to the center plug, covers a base pipe 21 by the outer race of bearing 22 again, singly turn to flywheel 23 and be right after this again, whole affixed this belt gear 24, and so tightly be attached at one of this rear wheel 10 side, this dentation belt 25 then encloses the axle center of motor gear 26 of this belt gear 24 of hoop and other end, this motor 28 then connects this storage battery 27, so far finishes the pulley transmission mechanism 20 of integral body.

And when operation is implemented, see also Fig. 3, Fig. 4, Fig. 5 and cooperate shown in Fig. 1, the figure, at first, the bicyclist is with electric power starting, and this moment, these storage battery 27 supply powers were to motor 28, and CD-ROM drive motor 28 rotations, and the axle center of motor gear 26 on the motor 28 promptly can turn round, and affects dentation belt 25, and this belt gear 24 of phase interlock, then the running of this belt gear 24 can be advanced in drive rear wheels 10 rotations, as shown in Figure 3; And when Electrical Bicycle 30 stops, but then because of the set only single direction rotation of unidirectional commentaries on classics flywheel 23 of the utility model, as shown in Figure 4, therefore, when Electrical Bicycle 10 is static, this rear wheel 10 will form the idle running phenomenon, can still not affect dentation belt 25 and motor 28 as the person of commonly using, and makes motor 28 cross cause thermal damage.

Claims

1, a kind of Electrical Bicycle pulley apparatus, its position that ties up to this bicycle rear wheel is provided with a pulley transmission mechanism, it is characterized in that: this pulley transmission mechanism ties up to center mat one base pipe of rear wheel and a bearing and the unidirectional commentaries on classics flywheel side that is connected one belt gear is set, and at belt gear upper ring hoop one dentation belt, this dentation belt end in addition then encloses hoop one axle center of motor gear, give CD-ROM drive motor by a storage battery supply power, rotate and drive the dentation belt.
