[0031] Embodiment 1:

[0032] like Figure 3-6 As shown, the mechanical labor-saving transmission device disclosed in this embodiment includes an input crankshaft 9, an output crankshaft 10 and a plurality of transmission components; the input crankshaft 9 and the output crankshaft 10 are each provided with a plurality of cranks 15, which are suitable for connecting a plurality of the transmission components; each of the transmission components includes a first sprocket 11, a second sprocket 12, a chain 13 and a connecting seat 14, the first sprocket 11 is sleeved on the connecting rod journal of the input crankshaft 9; the connecting seat 14 is sleeved on the connecting rod journal of the output crankshaft 10, and the second sprocket 12 is installed on the connecting seat 14; the chain 13 is sleeved on the first sprocket 11 and the second sprocket 12.

[0033] In the above structure, the first sprocket 11 is fixedly mounted on the crank 15 of the input crankshaft 9, and rotates and revolves under the drive of the input crankshaft 9. The first sprocket 11 is connected to the second sprocket 12 through the chain 13, which drives the second sprocket 12 to rotate on the one hand, and drives the second sprocket 12 to reciprocate up and down on the other hand; the second sprocket 12 is installed on the connecting seat 14, and the connecting seat 14 is mounted on the output crankshaft 10, so that the second sprocket 12 can drive the crank 15 of the output crankshaft 10 to rotate half a circle through the connecting seat 14 when moving upward, thereby realizing power transmission. There are multiple transmission components, and multiple transmission components work alternately to realize the full-circle drive of the output crank 15, thereby realizing the rotation drive of the output crankshaft 10. In the above process, the transmission component causes the chain 13 and the second sprocket 12 to form a movable pulley structure through the change of the displacement at the crank 15 of the input crankshaft 9, which drives the output crankshaft 10 to rotate to realize transmission on the one hand, and realizes labor saving through the movable pulley structure on the other hand.

[0034] Furthermore, the input crankshaft 9 and the output crankshaft 10 are each provided with two cranks 15, the number of the transmission components is two, and the angle between the two cranks 15 on the same crankshaft is 180 degrees. Figure 3 As shown, AA is a group of transmission components, BB is another group of transmission components, and at the same time, their states are as follows: Figure 4-5 Of course, multiple transmission components and cranks 15 can also meet the above working requirements. In the input crankshaft 9, the edges of the tooth root circles of the two first sprockets 11 coincide with the center of the input crankshaft 9.

[0035] Furthermore, in this embodiment, the transmission assembly further includes a steering wheel set, on which the chain 13 is wound, and is suitable for adjusting the transmission direction of the chain 13. The provision of the steering wheel set can free the transmission from limiting the positions of the input crankshaft 9 and the output crankshaft 10, so that the input crankshaft 9 and the output crankshaft 10 can be placed not only up and down, but also horizontally, thereby facilitating application.

[0036] Preferably, the steering wheel set includes at least four steering wheels 17, wherein two steering wheels 17 are arranged between the first sprocket 11 and the second sprocket 12, and are suitable for making the chain 13 wound around the first sprocket 11 to be transmitted horizontally; and two steering wheels 17 are arranged above the second sprocket 12, and are suitable for making the chain 13 wound around the second sprocket 12 to be transmitted vertically. Figure 4-5 As shown, in this embodiment, the steering wheel group is provided with five steering wheels 17, two of which are used for steering the chain 13 on the first sprocket 11, two are used for steering the chain 13 on the second sprocket 12, and the other is used for position adjustment, thereby adjusting the transmission direction of the chain 13 to avoid mutual interference between chains 13 in different directions.

[0037] Further, the first sprocket 11 and the second sprocket 12 are both double-row sprockets, and the chain 13 is a double-row chain 13. The double-row sprockets and the double-row chain 13 are suitable for improving the connection strength and transmission stability.

[0038] Furthermore, the connecting seat 14 includes a base and a pin; one end of the base is provided with a through hole suitable for fitting the output crankshaft 10, and the other end is provided with a pair of lugs with through holes; the pin is connected to the through hole and is parallel to the through hole, and the pin is suitable for installing the second sprocket 12. Specifically, the base can be a split structure, and the interface of the split structure is the plane where the central axis of the through hole is located, which is suitable for movably fitting onto the output crankshaft 10; the base can also be an integrated structure, in which case the output crankshaft 10 is a split structure, which facilitates the installation of the base to the connecting rod journal of the output crankshaft 10. The second sprocket 12 and the pin are movably fitted.

[0039] Furthermore, the above structure further includes a chassis 8, and the input crankshaft 9, the output crankshaft 10, and the steering wheel set are mounted in the chassis 8. Further, it also includes a plurality of crossbars, which are mounted in the chassis 8 and are suitable for mounting the steering wheel 17. Specifically, in the plurality of sets of the steering wheel sets, the steering wheels 17 with the same position and function are mounted on the same crossbar.

[0040] Furthermore, the above structure further comprises a swing arm 18, one end of which is rotatably connected to the side wall of the chassis 8, and the other end is provided with a round hole, the length direction of which is consistent with the length direction of the swing arm 18, and is mounted on the pin. In the above structure, the swing arm 18 can rotate up and down relative to the side wall, and is connected to the pin through the round hole, so that the second sprocket 12 connected to the pin can only move up and down, and the round hole is provided to avoid the influence of the rotation of the swing arm 18 on the pin. The chassis 8 is made of cast iron or all-aluminum material.

[0041] Further, in the above structure, the direction control wheel set includes at least two meshing transmission gears 16, one of which is mounted on the input crankshaft 9, and the other is mounted on the output crankshaft 10. The above structure is suitable for controlling the rotation direction of the output crankshaft 10 by the rotation direction of the input crankshaft 9. In addition, the above structure is also used for transmission when the transmission component fails.

[0042] Furthermore, a lubrication oil supply system is also provided in the chassis 8 for lubrication.

[0043] Embodiment 2:

[0044] like Figure 7-8 As shown, this embodiment discloses a vehicle transmission system, including the mechanical labor-saving transmission device 6 described in Example 1.

[0045] Studies have shown that if the total weight of a car is reduced by 10%, the fuel efficiency can be improved by 6%-8%; if the curb weight of the car is reduced by 100 kg, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters, and the range of a pure electric car can be increased by 6-11% for every 100 kg weight reduction. After installing the above-mentioned mechanical labor-saving transmission device 6, a fuel car or electric car with a self-weight of 2 tons can save one time of power or torque output of the engine 1 or motor, or is equivalent to reducing the gravity of half the vehicle's self-weight, thereby reducing 1 / 2 fuel consumption or electric energy consumption and doubling the mileage. That is, after a fuel car or electric car with a self-weight of 2 tons is equipped with the above-mentioned mechanical labor-saving transmission device 6, it is equivalent to reducing the weight of the car by 1 ton, then the fuel consumption per 100 kilometers is reduced by 3-6 liters, and the mileage of the pure electric car is increased by 60-110 kilometers, thereby reducing carbon emissions and energy consumption, and being more economical and environmentally friendly.

[0046] Furthermore, this embodiment also discloses a method for using the mechanical labor-saving transmission device 6:

[0047] First, assemble the mechanical labor-saving transmission device 6 according to the above structure, and then connect it to the transmission system. Specifically, connect the input crankshaft 9 to the power output end, and connect the output crankshaft 10 to the execution end. The power output end drives the input crankshaft 9 to rotate, and the rotation of the input crankshaft 9 drives at least two first sprockets 11 to rotate and revolve. The rotation and revolution of the first sprocket 11 can drive the second sprocket 12 to reciprocate up and down under the restriction of the swing arm 18 while rotating through the chain 13 and the steering wheel group. The up and down movement of the second sprocket 12 drives the connecting seat 14 to drive the output crankshaft 10 to rotate half a circle. At least two transmission components act alternately to realize the rotation of the output crankshaft 10. And due to the restriction of the direction control wheel group, the transmission direction of the output crankshaft 10 is a limited direction. The rotation of the output crankshaft 10 can drive the execution end to rotate, and then realize power transmission.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
