The chain 17 further drives the small sprocket 18 to rotate, so that the small sprocket 18 drives the rear wheel 19 to rotate synchronously to achieve the driving overall. The role of bicycle 10 is going forward. If the bicycle 10 is a pure foot bicycle, of course, the pedal 16 must be stepped on to advance; if it is a bicycle, it will help to advance after the pedaling is started; if it is an electric bicycle, the door is turned by turning the handle As will be advanced, it is known that the conventional bicycle 10 does not have to step on the pedal 16 as a necessary means of advancement. The above illustrates the possible structural composition and function of the bicycle 10.

In addition to the basic structural components described above, the bicycle 10 further includes a transmission mechanism 20, a housing 30 and a rotating ring 40. As shown in FIGS. 2 to 4, one end of the transmission mechanism 20 is coaxial with the small sprocket 18 of the bicycle 10. When the small sprocket 18 of the bicycle 10 is rotated by the chain 17, the transmission mechanism 20 is synchronously rotated; the outer casing 30 is mounted on the rear section of the frame 11 of the bicycle 10 for the transmission mechanism. The portion 20 and the rotating ring 40 are mounted inside the outer casing 30 (described in more detail later); the pivot ring 40 is coupled to the other end of the transmission mechanism 20 by mounting a one-way clutch bearing 41, such that The transmission mechanism 20 can drive the rotating ring 40 to perform a one-way rotation (more on this later).

As shown in FIGS. 2 to 4, the transmission mechanism 20 is a soul portion of the present invention, which is connected between the small sprocket 18 and the rotating ring 40, whereby the power generated by the rotation of the small sprocket 18 is transmitted to the rotation. The ring 40 is driven to drive the rotating ring 40 to generate a rotating centrifugal force when the bicycle 10 is stepped on, thereby improving the stability of the body when the bicycle 10 travels, and the rotation of the rotating ring 40 can be accompanied by the generation of electricity. Rotate the light and/or sound to increase the safety of the car.

Referring to FIG. 2, FIG. 4 and FIG. 5, the transmission mechanism may include: a first gear 21 coaxially fixed to the small sprocket 18 of the bicycle 10, so when the small sprocket 18 rotates, the first The gear 21 is synchronously rotated; a second gear 22 is disposed on the outer side of the first gear 21 and is engaged with the first gear 21 to receive the driving rotation of the first gear 21, the first and second gears 21 And 22 are preferably provided with the bevel gears engaged with each other, so that the central shaft 221 of the second gear 22 extends upwards upward, and the central shaft 221 passes through a set of bearings fixed to the frame 11. 222, the center shaft 221 can be stably existed and rotated by the support of the frame 11 and the bearing 222; and a third gear 23 is fixed to the central shaft 221 of the second gear 22 to receive The central shaft 221 directly drives the rotation; and A fourth gear 24 is supported by a central shaft 241 and directly meshed with the third gear 23 to receive the third gear 23 to directly rotate. The bottom end of the central shaft 241 is supported by a bearing 242. The bearing 242 is fixed to the frame 11 , and the top end of the central shaft 241 is inserted into the one-way clutch bearing 41 , so that the one-way clutch bearing 41 receives the rotation of the fourth gear 24 .

According to the above configuration, when the pedal 16 of the bicycle 10 is stepped forward, the rear wheel 19 pushes the entire bicycle 10 forward through the transmission of the large sprocket 15, the chain 17 and the small sprocket 18, at the small At the beginning of the rotation of the sprocket 18, the first gear 21 rotates synchronously, and the second gear 22, the central shaft 221 and the third gear 23 are both rotated, and the third gear 23 drives the fourth gear 24, The central shaft 241 and the one-way clutch bearing 41 both rotate. When the pedal 16 of the bicycle 10 is in a state of being continuously stepped on (that is, when the small sprocket 18 continues to rotate forward), the one-way clutch bearing 41 The rotation of the fourth gear 24 drives the rotating ring 40 synchronously via the one-way clutch bearing 41, and the bicycle 10 advances faster (that is, the small sprocket 18 continues). When the forward rotation is faster, the rotating ring 40 also rotates synchronously faster. The rotational centrifugal force accompanying the rapid rotation of the rotating ring 40 makes the bicycle 10 more stable, so that the safety of the bicycle 10 during traveling can be improved.

When the bicycle 10 is stopped at a sufficient speed or begins to decelerate, the rider stops pedaling the pedal 16, but rests the sole on the pedal 16, in which state the small sprocket 18, the rotation is stopped, and the first gear 21, the second gear 22, the central shaft 221, the third gear 23, the fourth gear 24, and the central shaft 241 are also stopped, but the rotating ring 40 Originally in a state of rapid rotation, the unidirectional clutch bearing 41 itself is activated by the action of "off" at the moment when the small sprocket 18 is stopped, so that the rotating ring 40 and the unidirectional clutch bearing 41 can continue to rotate at a high speed. However, the inside of the one-way clutch bearing 41 is stopped by the central shaft 241. Then when the pedal 16 is stepped on again, Through the above-mentioned layer driving, the central shaft 241 re-traverses the internal rotation of the one-way clutch bearing 41, so that the one-way clutch bearing 41 itself is instantaneously changed into a "closed" action state, and the rotating ring 40 is re-driven to rotate synchronously.

In order to increase the safety of the vehicle, a plurality of decorative panels 50 can be connected to the ring body of the rotating ring 40. As shown in FIGS. 2-6, the plurality of decorative panels 50 are equally spaced apart from the ring body of the rotating ring 40.

A power source 61 can be fixed to the power source 60 to generate power for the power source 60. The power of the power source 61 can be stored in the battery, or can be stored by solar energy, or can be utilized. The bicycle 10 itself is frictionally generated when stepping on the road, and can be powered by the main power source of the electric bicycle.

As can be seen from the above description, basically, when the rider rides on the bicycle, the rotation of the rotating ring 40 can be synchronously generated by the transmission of the transmission mechanism 20, so that the rotating ring 40 is fast. The centrifugal force generated by the rapid rotation will help the vehicle to be more stable, so that the safety of the bicycle 10 during traveling can be improved. In addition, the ring body of the rotating ring 40 is further connected with a plurality of decorative plates 50, which can be synchronously rotated with the rotating ring 40, thereby improving the joyful atmosphere of the bicycle 10 having a fast rotating object on the frame 11 when traveling; If the plurality of decorative panels 50 are further provided with small illuminating members 51, and the small centrifugal power generating mechanism installed inside the rotating ring 40 is provided, the small illuminating members 51 are illuminated by the rotation accompanying the electric power. The joyful state of rotating the decorative panel 50 is multiplied. When the bicycle 10 travels, the rotation of the rotating ring 40 on the frame 11 is sufficient to attract more attention on the road. If more of the decorative panel 50 is rotated, it will be more attractive. Other people's attention, and more with the illuminating parts accompanying the rotation, in addition to attracting the attention of others, will also attract the attention of others farther, so it is indeed possible to increase the safety of the car.

In conclusion, the present invention can achieve the intended function and purpose, and the detailed description can be implemented by those skilled in the art, and the above embodiments are only used to illustrate the present invention, and all equivalent structures. The changes are still within the scope of the invention.
