Embodiment 1
[0108] Such as figure 1 and figure 2As shown, the driving device of the present invention includes a drive gear 10, a first ratchet mechanism, a second ratchet mechanism, a first sector gear 4 (ie, a left sector gear), a second sector gear 5 (ie a right sector gear), a first pedal 14 (i.e. left pedal), second pedal 15 (i.e. right pedal) and bevel gear set. The first ratchet mechanism and the second ratchet mechanism are symmetrically arranged on both sides of the drive gear 10 and can alternately drive a drive gear 10 to rotate in the same direction; the first sector gear 4 meshes with the first ratchet mechanism and drives the first ratchet mechanism Rotate, the second sector gear 5 meshes with the second ratchet mechanism and drives the second ratchet mechanism to rotate; one end of the first pedal 14 is the stepping end, the other end is the connecting end, the connecting end of the first pedal 14 is connected to the first sector One end of the gear 4 connected to the se...
Embodiment 2
[0113] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a coaxial and fixed speed change mechanism is added, and the speed change mechanism includes a secondary main gear 21 and a secondary pinion gear 22 to increase the output speed of the driving device . The driving gear 10 meshes with the secondary pinion 22 and drives it to rotate, and the secondary pinion 22 drives the secondary main gear 21 to rotate. Because the outer diameter of the wheel of the secondary pinion 22 is much smaller than that of the driving gear 10, when the driving gear 10 rotates once, it will drive the secondary pinion 22 to rotate several times, and simultaneously the secondary main gear 21 will also rotate with the secondary The same number of turns of the pinion, thus increasing the speed of rotation.
[0114] In order to ensure that the drive gear 10 rotates clockwise, the first sector gear 4 and the second sector gear 5 adopt image 3 T...
Embodiment 3
[0117] Such as Figure 5 to Figure 8 As shown, the structure of the driving device of the third embodiment is basically the same as that of the first embodiment, the difference is that the driving gear 10 is placed horizontally, and the first ratchet mechanism and the second ratchet mechanism are located on the lower and upper sides of the driving gear 10 respectively. A sector gear 4 and a second sector gear 5 are located on the lower and upper sides of the driving gear 10 respectively, while the first pedal 14 and the second pedal 15 are located above the driving gear 10 . Simultaneously the structure of described bevel gear set in embodiment three is also different from embodiment one, in this embodiment, described bevel gear set comprises the 4th bevel gear 26, the 5th bevel gear 27, the 6th bevel gear 28 and the seventh bevel gear 29, the fourth bevel gear 26 is connected with one end of the first pedal 14 through an engagement device, the fifth bevel gear 27 is fixedly c...
