[0025] The structure of the power output sun gear fixed end cover is consistent with that of the power input sun gear fixed end cover.

[0027] To summarize, the power output gear of the power input sun gear assembly engages with the large tooth layer of the planetary gear on the first-stage dual power planetary gear carrier assembly, and the small tooth layer of the planetary gear engages with the first-stage ring gear. The power output planetary gear on the first-stage dual power planetary gear carrier assembly engages not only with the intermediate sun gear, but also with the first-stage ring gear; the intermediate sun gear engages not only with the power output planetary gear on the first-stage dual power planetary gear carrier assembly, but also with the large tooth layer of the power input planetary gear on the second-stage dual power planetary gear carrier assembly; the small tooth layer of the power input planetary gear on the second-stage dual power planetary gear carrier assembly engages with the second-stage ring gear, and the power output planetary gear engages not only with the second-stage ring gear, but also with the power input gear of the power output gear assembly.

[0028] The power is transmitted from the sun gear of the power input sun gear assembly to the power input planetary gear on the first-stage double power planetary gear carrier. The power input planetary gear then transmits the power to the planetary gear carrier. The power output planetary gear on the planetary gear carrier then transmits the power to the intermediate sun gear. The intermediate sun gear then transmits the power to the power input planetary gear on the second-stage double power planetary gear carrier. The power input planetary gear then transmits the power to the planetary gear carrier. The planetary gear carrier then transmits the power to the power output planetary gear. The power output planetary gear then transmits the power to the power output sun gear.

[0029] Power is input from one sun gear, passes through the planetary carrier assembly, and finally output from the other sun gear.

[0030] In order to more intuitively and conveniently calculate the size of power input and external power output, as well as the size of the speed of the power input part and the speed of the power output part, because it is a gear transmission, the power arm takes the original length minus twice the tooth depth as the power arm, and the tooth depth is unified as 0.3 cm.

[0031] Assuming that the radius of the power input gear of the power input sun gear assembly is 4 cm, the power arm is set to be consistent with the resistance arm of the power output sun gear, offsetting each other, the resistance arm is 4 cm, and the fulcrum is at the center of the sun gear; The radius of the large tooth layer of the power input planetary gear on the first-stage dual-power planetary gear carrier assembly is 8 cm, and the radius of the small tooth layer is 2 cm, that is, the power arm is 8+2-0.6=9.4 cm, the resistance arm is 2 cm, and the fulcrum is at the position where the power input planetary gear contacts the first-stage ring gear; the radius of the power output planetary gear on the dual-power planetary gear carrier assembly is 5 cm, that is, the power arm is 5-0.6=4.4 cm, the resistance arm is 5+5=10 cm, and the fulcrum is at the position where the power output planetary gear contacts the first-stage ring gear; the distance from the center of the installation axis of the power input planetary gear on the dual-power planetary gear carrier to the center of the first-stage dual-power planetary gear carrier is 8+4=14 cm, and the distance from the center of the installation axis of the power output planetary gear on the dual-power planetary gear carrier to the center of the dual-power planetary gear carrier is 5+4=9 cm, that is, the power arm is 14 cm, the resistance arm is 9 cm, and the fulcrum is at the center of the dual-power planetary gear carrier; The radius of the middle sun gear is 4 cm, the power arm is 4-0.6=3.4 cm, the resistance arm is 4 cm, and the fulcrum is at the center of the middle sun gear; The radius of the large tooth layer of the power input planetary gear on the first-stage dual-power planetary gear carrier assembly is 8 cm, and the radius of the small tooth layer is 2 cm, that is, the power arm is 8+2-0.6=9.4 cm, the resistance arm is 2 cm, and the fulcrum is at the position where the power input planetary gear contacts the first-stage ring gear; The radius of the power output planetary gear on the secondary dual power planetary gear carrier assembly is 5 cm, that is, the power arm is 5-0.6=4.4 cm, the resistance arm is 5+5=10 cm, and the fulcrum is at the position where the power output planetary gear contacts the secondary gear ring; the distance from the center of the installation axis of the power input planetary gear on the dual power planetary gear carrier to the center of the dual power planetary gear carrier is 8+4=14 cm, and the distance from the center of the installation axis of the power output planetary gear on the dual power planetary gear carrier to the center of the dual power planetary gear carrier is 5+4=9 cm, that is, the power arm is 14 cm, the resistance arm is 9 cm, and the fulcrum is at the center of the dual power planetary gear carrier; The radius of the power input gear of the power output sun gear is 4 cm, that is, the power arm is 4-0.6=3.4 cm, and the resistance arm is consistent with the power arm of the sun gear, offsetting each other.

[0032] To sum up, the speed ratio of the power input sun gear and the dual power planetary gear carrier in the first-stage dual power planetary gear carrier assembly is (4+8+2+4)÷4=4.5, that is, the power input sun gear rotates 4.5 circles, and the dual power planetary gear carrier rotates one circle; the speed ratio of the dual power planetary gear carrier in the first-stage dual power planetary gear carrier assembly and the intermediate sun gear is (4+5+5+4)÷4=4.5, that is, the dual power planetary gear carrier rotates 1 circle, and the intermediate sun gear carrier rotates 4.5 circles; the speed ratio of the dual power planetary gear carrier in the second-stage dual power planetary gear carrier assembly and the intermediate sun gear is (4+8+2+4)÷4=4.5, that is, the intermediate sun gear rotates 4.5 circles, and the dual power planetary gear carrier rotates 1 circle; the speed ratio of the dual power planetary gear carrier in the second-stage dual power planetary gear carrier assembly and the power output sun gear is (4+5+5+4)÷4=4.5, that is, the dual power planetary gear carrier rotates 1 circle, and the power output sun gear carrier rotates 4.5 circles.

[0033] It can be seen from this that when the power input sun gear rotates 4.5 circles, the dual power planetary gear carrier of the first-stage dual power planetary gear carrier assembly rotates one circle, the intermediate sun gear rotates 4.5 circles, the dual power planetary gear carrier of the second-stage dual power planetary gear carrier assembly rotates one circle, and the power output sun gear rotates 4.5 circles, that is, the speed of the power output gear is not less than the speed of the sun gear.

[0034] Assuming that a power value of 100 is input to the power input sun gear, the power output from the power output sun gear is: 100÷4×9.4÷2×14÷9×4.4÷10×3.4÷4×9.4÷2×14÷9×4.4÷10×3.4=747.6700303 To sum up, it can be seen that a smaller power can output a huge power through the above-mentioned labor-saving planetary gear system, and the speed of the power input part can be equal to the speed of the power output part; it has the characteristics of strong practicality, high work efficiency and green environmental protection, and when the speed of the power input part is equal to the speed of the power output part, the power output is greater than the power input.

[0035] The important features of the above-mentioned labor-saving planetary gear train are: A relatively small power can output a huge power through the above-mentioned labor-saving planetary gear train.

[0036] The speed of the power output member may be no less than the speed of the power input member.

[0037] According to the two characteristics of the above-mentioned labor-saving planetary gear train, a power motor with relatively small power can be used to output extremely large power through the labor-saving planetary gear train without reducing the output speed.

[0038] The main body of the motor-driven power generation system includes a drive motor, a labor-saving planetary gear train, a generator, an electronic control component, a battery pack, and a cooling system; The driving motor is connected to the labor-saving planetary gear train to drive the sun gear to rotate; the labor-saving planetary gear train is not only connected to the driving motor, but also connected to the generator, and the power output gear of the labor-saving planetary gear train is connected to the generator to drive the generator to rotate; The electronic control component has a group of wires connected to the drive motor, a group of wires connected to the battery, a group of wires connected to the generator, a group of wires connected to the cooling system, and a group of wires connected to the power output drive motor.

[0039] The electric control component is also provided with a start switch and a power output drive motor speed control and a steering controller.

[0040] The electric control component is provided with the function of rectifying and stabilizing the current transmitted from the generator and then distributing it to various electronic components, and is also provided with a port for transmitting current to the outside.

[0041] The cooling system body includes a refrigerant compressor, a drive motor and an evaporator in a generator, an evaporator in an electronic control component, a condenser, a fan, and a temperature sensor.

[0042] The power motor, drive motor, generator and electronic control assembly are all provided with condensers.

[0043] According to the two characteristics of the above-mentioned labor-saving planetary gear system, a relatively small-power driving motor drives a relatively large-power generator through a labor-saving planetary gear system, and the electricity generated by the relatively large power is transmitted to the electronic control component, which rectifies and stabilizes the transmitted current, and then distributes it to various electronic components and external current transmission ports. The electronic control component also has the function of temporarily storing electrical energy; and the driving motor uses the electricity transmitted to the electronic control component by the battery only when it starts. After the driving motor is started, when the electronic control component detects that the generator has current transmitted, it will give priority to using the current transmitted by the generator to work, not only will the battery power no longer be used, but when the electronic control component detects that the battery power is reduced to a set value, it will charge the battery. power; when the battery is not used for a long time, the battery power is lost, or the battery is damaged, and the drive motor cannot be started normally, an external power supply can be connected to the corresponding port of the electronic control component to start the drive motor; after starting the drive motor, when the temperature sensor connected to the drive motor by the cooling system reaches a set value, or the temperature sensor connected to the generator reaches a set value, the temperature of the temperature sensor in the electronic control component reaches a set value, or the temperature of the temperature sensor in the power motor reaches a set value, the compressor is started to cool the drive motor or generator and the electronic control component, and the power output drive motor. The cooling system can also cool the drive motor or generator, the electronic control component and the power output drive motor separately.

[0044] The present invention has the characteristics of strong practicality, high working efficiency and green environmental protection. It not only does not have the limitation of limited power stored by batteries as power sources and the safety hazards of spontaneous combustion or explosion, but also does not have the disadvantages of using fuel engines to drive power generation in traditional power generation systems as power sources, which consumes fuel and also emits a large amount of exhaust gas to pollute the environment.

[0045] The above are merely preferred embodiments for illustration, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
