In some embodiments of the present disclosure, the base includes a bottom plate 17 and a second support bracket 6 disposed on the bottom plate 17. The base provides a mounting foundation for the transmission assembly, the output assembly and the input assembly, and the base can be composed of components such as plates and brackets, and the like, so that a person skilled in the art can adaptively set the structure of the base according to actual structure setting or assembly requirements. The transmission assembly comprises a lever 1 hinged on a second support frame 6 and a first gear 3 rotatably connected on the second support frame 6, wherein one end of the lever 1, which is relatively long with respect to the hinge point of the lever, is an input end, and the other end of the lever 1, which is relatively short with respect to the hinge point, is an output end.

In some embodiments of the present disclosure, the shape of the first gear 3 is a sector, and when the first gear 3 is a sector, the hinge point of the lever 1 may not be obstructed by the first gear 3, so that the hinge point of the lever 1 may be closer to the driving part (2), the moment arm of the output end of the lever 1 becomes shorter, and the force conversion efficiency becomes higher.

In one embodiment of the present disclosure, the first gear 3 is eccentrically provided with a driving part 2 for being coupled with the output end of the lever 1, and the driving part 2 may be provided in a column-shaped, ball-shaped, or the like structure, which is not limited in the present invention.

In detail, the driving hole 7 is an elongated hole, and the longitudinal direction of the driving hole 7 coincides with the extending direction of the lever. The driving part 2 can slide in the driving hole 7, and when the lever 1 swings, the first gear 3 is driven to transmit by the cooperation of the driving hole 7 and the driving part 2.

In the driving process, because the circle centers and the paths of the rotation of the lever output end and the driving part 2 are different, the angular speeds of the rotation of the lever output end and the driving part 2 are different, the lever output end can provide driving force for the driving part 2 to rotate the first gear 3, and because the two rotation angular speeds are different, the driving part 2 needs to slide in the driving hole 7 of the lever output end, so that the driving can be normally performed.

The transmission device of the present disclosure further includes an output assembly including an output shaft 4, and a second gear 5 and a one-way bearing 16 connected to the input shaft 4, where the output assembly is configured to convert and amplify the input end to a driving force for driving an external device to perform work.

In one embodiment of the present disclosure, as shown in fig. 3, the third support frame 8 is disposed on the bottom plate 17, and the output shaft 4 is rotatably connected to the third support frame 8 or the output shaft may be rotatably connected to a support of an external structure. The output shaft 4 is also provided with an output wheel 15 for external connection. The third support frames 8 may be provided with at least two at intervals, and the output shaft 4 is rotatably connected to the at least two third support frames 8, so that the structure is more stable.

In one embodiment of the present disclosure, the transmission is provided with at least two sets, the input assemblies of at least two sets of transmissions being configured for synchronous movement, the links 10 of at least two sets of transmissions being configured to be located at different travel positions of the respective input assemblies.

In detail, when at least two sets of transmission mechanisms work, the input assembly drives the input shaft 12 to rotate through the input wheel 13, the input shaft 12 drives the rotating disc 14 to rotate, the connecting rod 10 is hinged with the rotating disc 14 and the lever 1, and the connecting rod 10 drives the lever 1 to swing.

In a specific embodiment of the present disclosure, two connecting rods 10 in at least two sets of transmission mechanisms are hinged to respective rotating discs 14 through eccentric shafts 9, the positions of at least two eccentric shafts 9 may be set at the same positions of respective rotating discs 14, and in the process of driving lever 1 to swing, input assemblies of at least two transmission mechanisms may synchronously drive lever 1 to swing so as to enable first gear 3 to rotate, and further drive second gear 5 to rotate, so as to complete driving of output shaft 4.

In another particular embodiment of the present disclosure, as shown in the front view of fig. 2, the position of at least two eccentric shafts 9 may be arranged on opposite sides of the respective turning disc 14, with two hinge points being arranged symmetrically with respect to the center of the circle in the front projection of the two turning discs 14. In the process of driving the lever 1 to swing, as the connecting rod 10 is hinged on different positions of the rotating disc 14, at least two sets of transmission mechanisms do work respectively when the lever 1 is driven to swing to finish driving the output shaft 4, and when one set of transmission mechanism drives the output shaft 4 to rotate, the other set of transmission mechanism does not do work on the output shaft 4 but moves in the opposite direction, but because the one-way bearing 16 is arranged on the output shaft 4, the opposite movement only enables the second gear 5 to idle under the action of the one-way bearing 16 and does not do work on the output shaft 4.

When the device is specifically used, the external power device drives the input wheel 13 to rotate, then drives the input shaft 12 and the rotating disc 14 to rotate, and the rotating disc 14 drives the connecting rod 10 to rotate, so as to drive the input end of the lever 1 to swing up and down, and the output end of the lever 1 drives the first gear 3 to rotate through the driving part 2 when swinging. When the first gear 3 rotates, the second gear 5 meshed with the first gear 3 also rotates together, so that the output shaft 14 is driven to rotate, and the output wheel 15 arranged on the output shaft 14 rotates to provide power for the movement of an external device. Because the force at the two ends of the lever is the force arm of the force multiplied by the force, the moment at the output end is smaller than the moment at the input end, so that the driving force at the smaller input end can be converted into the driving force at the larger output end, and the energy conversion efficiency is improved.

The transmission device can be applied to a vehicle, and the vehicle further comprises the transmission device, and by installing the transmission device, the efficiency of converting energy generated by an engine of the vehicle in operation into wheel movement energy is improved, and energy sources are saved.
