Abstract

The invention provides a labor-saving bicycle. The labor-saving bicycle comprises an intermediate shaft of pedals, a chain wheel, a chain I, a rear axle, a box body and a casing of the box body, wherein an output shaft, a flywheel I, an input shaft, a flywheel II, a chain II and a transmission module are also arranged on the box body, the flywheel I is arranged on the output shaft, the flywheel II is arranged on the input shaft, the intermediate shaft of the pedals is in transmission connection with the input shaft through the chain II, and the input shaft is in transmission connection with the output shaft through the transmission module. According to the labor-saving bicycle, as the output shaft, the flywheel I, the input shaft, the flywheel II, the chain II and the transmission module are arranged on the box body, and chain transmission, gear transmission and lever transmission are employed in the transmission module, a good labor-saving effect is finally achieved.

Example Embodiment

[0012] Such as figure 1 with figure 2 As shown, a labor-saving bicycle includes a pedal shaft 1, a chainring 2, a chain I3, a rear axle 4, a box body 5, and a box body shell 6, characterized in that the box body 5 is also provided with an output shaft 7, Flywheel Ⅰ8, input shaft 9, flywheel Ⅱ10, chain Ⅱ11 and transmission assembly 12. Flywheel Ⅰ8 on output shaft 7, flywheel Ⅱ10 on input shaft 9, pedal shaft 1 through chain Ⅱ11 and input shaft 9 transmission link, input shaft 9 through the transmission assembly 12 and the output shaft 7 transmission link.

[0013] Such as image 3 As shown, the structure of the transmission assembly 12 is as follows: the input shaft 9 has a disc 13 and the disc 13 has a rotating shaft Ⅰ14, the rotating shaft Ⅰ14 is connected to the movable shaft Ⅲ23 through the transmission rod Ⅰ15, and the movable shaft Ⅲ23 is connected to the fixed shaft through the rod Ⅱ16 Ⅰ17 is connected, fixed shaft Ⅰ17 is fixed on box 5, one end of connecting rod 18 is connected with movable shaft Ⅲ23, the other end of connecting rod 18 is connected with movable shaft Ⅳ24, movable shaft Ⅳ24 is connected with fixed shaft Ⅱ20 through rod Ⅰ19, rod Ⅰ19 and rod There are movable shaft Ⅰ21 and movable shaft Ⅱ22 on Ⅱ16 respectively. Rotating shaft Ⅱ25 is arranged between movable shaft Ⅰ21 and movable shaft Ⅱ22. Rotating shaft Ⅱ25 is connected to movable shaft Ⅰ21 and movable shaft Ⅱ22 through transmission rod Ⅱ26 and transmission rod Ⅲ27, respectively. The rotating shaft Ⅱ 25 is connected with the output shaft 7.

[0014] When in use, the pedal shaft 1 drives the input shaft 9 to rotate through the chain II11, and the input shaft 9 drives the disc 13 to rotate. The rotation axis I14 on the disc 13 drives the transmission rod I15 to reciprocate along with the circular rotation of the disc 13. In turn, the fixed shaft I17, the fixed shaft II20 and the movable shaft IV24 are driven to rotate, so that the connecting rod 18, the rod I19 and the rod II16 are reciprocated. The reciprocating motion of the connecting rod 18 and the rod I19 drives the movable shaft I21 and the movable shaft II22 to rotate, thereby causing The rotating shaft Ⅱ25 rotates around the output shaft 7, and the rotating shaft Ⅱ25 drives the output shaft 7 to rotate. The flywheel I8 on the output shaft 7 drives the rear axle 4 to rotate through the chain I3.

[0015] Such as Figure 4 As shown, the fixed shaft Ⅰ17 and the fixed shaft Ⅱ20 are two fixed shafts. The working process (1): When the large angle ∠A becomes the small angle ∠A', a force is generated, and the force acts on any point of the rod Ⅰ19 except the fixed shaft Ⅱ20 point .

[0016] Such as Figure 5 As shown, the working process (2): After the input shaft 9 rotates 180°, the large angle ∠B’ becomes the small angle ∠B to generate force, which acts on any point of rod II16 except the point 17 of fixed axis I.

[0017] The invention can be used on one side or on both sides.
