The third driving wheel 34b is coaxially connected and fixed with the second driving wheel 32b, so that when the second driving wheel 32b rotates in the forward direction, the third driving wheel 34b rotates in the forward direction along with the second driving wheel 32 b. The fourth driving wheel 35b is connected with the third driving wheel 34b through the second driving chain 36, so that the fourth driving wheel 35b can synchronously realize forward rotation along with the third driving wheel 34b, and the fourth driving wheel 35b is connected with the flywheel 23, so that the flywheel 23 can be driven to realize forward rotation, and the front wheel 11 is driven to advance. In this embodiment, the first, second, third and fourth driving wheels 31b, 32b, 34b and 35b are gears. It should be noted that, in other preferred embodiments of the present invention, any one of the first driving wheel 31b and the second driving wheel 32b may be configured as a meshing disc, a double-toothed disc, or a pair of gears disposed at intervals, where the structure of the meshing disc is the same as that of the meshing disc in the second embodiment of the present invention, the structure of the double-toothed disc is the same as that of the double-toothed disc in the third embodiment of the present invention, and the structure of the pair of gears disposed at intervals is the same as that of the pair of gears disposed at intervals in the fourth embodiment of the present invention, and will not be repeated here.
Example six
Referring to fig. 17 to 18 together, a reverse pedal bicycle according to a sixth embodiment of the present invention will now be described. The reverse pedaling bicycle provided by the sixth embodiment of the present invention is basically the same as the reverse pedaling bicycle provided by the first embodiment of the present invention, except that:
in the present embodiment, the reverse transmission mechanism 30 includes a first transmission wheel 31c, a second transmission wheel 32c, a third transmission chain 371, a third transmission wheel 34c, a fourth transmission wheel 35c, a fourth transmission chain 372, and a first guide wheel 38. The first driving wheel 31c is disposed on the central shaft 21 and has the same rotation direction as the pedal assembly 22. Because the pedal assembly 22 is fixed on the bottom bracket 21, when the pedal assembly 22 rotates reversely, the bottom bracket 21 can be driven to rotate reversely, so that the first driving wheel 31c arranged on the bottom bracket 21 can rotate reversely at the same time. The second driving wheel 32c is rotatably installed on the frame 10, and the second driving wheel 32c is connected to the first driving wheel 31c through the third driving chain 371, so that the rotation direction of the second driving wheel 32c is the same as the rotation direction of the first driving wheel 31 c. The third driving wheel 34c is coaxially connected and fixed with the second driving wheel 32c, so that when the second driving wheel 32c rotates reversely, the third driving wheel 34c rotates reversely along with the second driving wheel 32 c. The third driving wheel 34c is connected to the fourth driving wheel 35c through the fourth driving chain 372, and the first guide wheel 38 is rotatably disposed on the frame 10, and is used for bypassing the fourth driving chain 372 to convert the reverse rotation of the third driving wheel 34c into the forward rotation of the fourth driving wheel 35c, and the fourth driving wheel 35c is connected to the flywheel 23 to drive the flywheel 23 to rotate forward, thereby driving the front wheel 11 to move forward.
In this embodiment, the first driving wheel 31, the second driving wheel 32, the third driving wheel 34 and the fourth driving wheel 35 are all gears, and in other preferred embodiments of the present invention, the first driving wheel 31, the second driving wheel 32, the third driving wheel 34 and the fourth driving wheel 35 may be configured in other forms according to actual needs, which will not be described herein.
Example seven
Referring to fig. 19 to 20, a reverse pedal bicycle according to a seventh embodiment of the present invention will now be described. The reverse pedaling bicycle provided by the seventh embodiment of the present invention has substantially the same structure as the reverse pedaling bicycle provided by the first embodiment of the present invention, except that:
in the present embodiment, the reverse transmission mechanism 30 includes a first transmission wheel 31d, a second transmission wheel 32d, a fifth transmission chain 391, a third transmission wheel 34d, a fourth transmission wheel 35d, a sixth transmission chain 392, and a second guide wheel 393. The first driving wheel 31d is disposed on the central shaft 21 and has the same rotation direction as the pedal assembly 22. Because the pedal assembly 22 is fixed on the bottom bracket 21, when the pedal assembly 22 rotates reversely, the bottom bracket 21 can be driven to rotate reversely, so that the first driving wheel 31d arranged on the bottom bracket 21 can rotate reversely at the same time. The second driving wheel 32d is rotatably installed on the frame 10, the second driving wheel 32d is connected to the first driving wheel 31d through the fifth driving chain 391, and the second guide wheel 393 is rotatably installed on the frame 10 and is used for bypassing the fifth driving chain 391 to convert the reverse rotation of the first driving wheel 31d into the forward rotation of the second driving wheel 32 d. The third driving wheel 34d is coaxially connected and fixed with the second driving wheel 32d, so that when the second driving wheel 32d rotates in the forward direction, the third driving wheel 34d rotates in the forward direction along with the second driving wheel 32 d. The third driving wheel 34d is connected with the fourth driving wheel 35d through the sixth driving chain 392, so that the fourth driving wheel 35d can rotate forward along with the third driving wheel 34d, and the fourth driving wheel 35d is connected with the flywheel 23, so as to drive the flywheel 23 to rotate forward, so as to drive the front wheel 11 to advance.
In the present embodiment, the first driving wheel 31d, the second driving wheel 32d, the third driving wheel 34d and the fourth driving wheel 35d are all gears, and it should be noted that, in other preferred embodiments of the present invention, the first driving wheel 31d, the second driving wheel 32d, the third driving wheel 34d and the fourth driving wheel 35d may be arranged in different manners according to actual needs, which is not limited in any way.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
