[0008] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0009] The power supply method and device of an electronic device of the present invention is only used as an embodiment, and the main body includes: a battery, a wire group, a power main control element, a motor drive power generation system, a wireless charging module, and an external power port; The battery has a set of wires connected to the power main control element, the power main control element has a set of wires connected to the drive motor of the motor-driven power generation system, a set of wires connected to the generator of the motor-driven power generation system, a set of wires connected to the wireless charging module, and a set of wires connected to the external power port; The power supply main control element is provided with the function of rectifying and stabilizing the current transmitted by the generator and then distributing it to various electronic components, the function of temporarily storing electricity, and a start switch; The motor-driven power generation system mainly includes a driving motor, a labor-saving planetary gear train, and a generator; The driving motor is connected to the labor-saving planetary gear train, driving the power input 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 sun gear of the labor-saving planetary gear train is connected to the generator, driving the generator to rotate; The labor-saving planetary gear train body includes: the labor-saving planetary gear train body includes: a power input sun gear, a planetary gear carrier, a power input planetary gear, a power output planetary gear, a ring gear, a power output sun gear, and a power output sun gear mounting cover; The power input sun gear is fixed on the rotor of the drive motor and is directly connected to the rotor of the drive motor; The planetary gear carrier is installed with power input planetary gears and power output gears, and is cylindrical, with a plurality of power input planetary gear mounting shafts arranged on one bottom surface, and a plurality of power output planetary gear mounting shafts arranged on the other bottom surface; The power input planetary gear is installed on the power input planetary gear installation shaft and is a double-layer gear, the large gear layer bites the power input sun gear, and the small gear layer bites the ring gear; The power output planetary gear is a single-layer gear, which is mounted on the power output planetary gear mounting shaft and not only engages with the power output sun gear, but also engages with the ring gear; The gear ring is provided with an inner gear ring and a planetary gear receiving hole, and the diameter of the inner gear ring is smaller than the diameter of the planetary gear receiving hole. The inner gear ring not only bites the small tooth layer of the power input planetary gear, but also bites the teeth of the power output planetary gear; The power output sun gear body includes a power input gear, a large shaft, a mounting and power output shaft; The power output sun gear is mounted on the power output sun gear mounting cover; The power output sun gear mounting cover is mounted and fixed on the gear ring.
[0010] The gear ring is fixed to one end of the driving motor and cannot rotate; The power input sun gear engages with the large tooth layer of the power input planetary gear, the small tooth layer of the power input planetary gear engages with the ring gear, and the power output planetary gear engages not only with the ring gear but also with the power output sun gear.
[0011] The driving motor drives the power input planetary gear of the labor-saving planetary gear system through the power input sun gear on the rotor. The power input planetary gear drives the planetary gear frame to rotate while rotating. The power output planetary gear on the planetary gear frame drives the power output sun gear to rotate, and the power output sun gear transmits power outward.
[0012] In order to more intuitively and conveniently calculate the speed, torque of the drive motor and the speed and torque of the power output gear, 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 to 0.2 cm.
[0013] Assume that the power generated by the drive motor is transmitted to the power input sun gear with a value of 10; the gear radius of the power input sun gear is 2 cm, that is, the resistance arm is 2 cm, the power arm and the resistance arm of the power output sun gear are the same, offset each other, and the fulcrum is at the center of the power input sun gear; the radius of the large tooth layer of the power input planetary gear is 12 cm, and the radius of the small tooth layer is 1.5 cm, that is, the power arm is 12+1.5-0.4=13.1 cm, the resistance arm is 1.5 cm, and the fulcrum is at the position where the power input planetary gear contacts the ring gear; the distance from the center of the power input planetary gear installation shaft on the planetary gear carrier to the center of the planetary gear carrier is 12+1.5=13 .5 cm, the distance from the center of the power output planetary gear installation shaft on the planetary gear frame to the center of the planetary gear frame is 5.75+2=7.75 cm, that is, the power arm is 13.5 cm, the resistance arm is 7.75 cm, and the fulcrum is at the center of the planetary gear frame; the radius of the large tooth layer of the power output planetary gear is 5.75 cm, that is, the power arm is 5.75-0.4=5.35 cm, and the resistance arm is 5.75×2=11.5 cm, and the fulcrum is at the contact position between the power input planetary gear and the ring gear; the gear radius of the power output sun gear is 2 cm, that is, the power arm is 2-0.2=1.8 cm, and the resistance arm is consistent with the power input sun gear and offsets each other.
[0014] To sum up, the speed ratio of the sun gear and the planetary gear carrier is (12+1.5+2+2)÷2=8.75, that is, the sun gear rotates 8.75 times and the planetary gear carrier rotates one circle; the speed ratio of the planetary gear carrier and the power output sun gear is (5.75+5.75+2+2)÷2=8.75; it can be seen that the rotor of the drive motor rotates 8.75 times and the planetary gear carrier rotates one circle, and the power output sun gear rotates 8.75 times when the planetary gear carrier rotates one circle. Therefore, when the rotor of the drive motor rotates one circle, the power output gear also rotates one circle, and the rotor speed of the drive motor is consistent with the speed of the power output gear.
[0015] The torque generated by the drive motor is transmitted to the power output gear as follows: 10÷2×13.1÷1.5×13.5÷7.75×5.35÷11.5×1.8=63.6957644 It can be seen that the labor-saving planetary gear train has the following characteristics: 1. The speed of the power input part can be equal to the speed of the power output part.
[0016] 2. Inputting a smaller power can output a huge power.
[0017] According to the two characteristics of the above-mentioned labor-saving planetary gear system, a relatively small-power driving motor is used to drive a relatively large-power generator through a labor-saving planetary gear system. The electricity generated by the relatively large-power generator is transmitted to the power main control component. The power main control component rectifies and stabilizes the transmitted current, and then distributes it to various electronic components. The power main control component also has the function of temporarily storing electrical energy. The driving motor uses the electricity transmitted to the power main control component by the battery only when it starts to start. After the driving motor is started, when the power main control component detects that there is current transmitted from the generator, it gives priority to using the current transmitted by the generator to work. Not only does it no longer use the battery power, but when the power main control component detects that the battery power is reduced to a set value, it will charge the battery. When the battery is charged to the set value, the motor-driven power generation system stops working. At this time, the power main control component uses the battery power. When the motor-driven power generation system is working to generate electricity, the power main control component no longer uses the battery power.
[0018] When the start switch is turned on, the power main control component transmits current from the battery through the drive motor connected to the motor-driven power generation system to start the drive motor. The drive motor drives the generator to generate electricity through the labor-saving planetary gear system. At this time, the motor-driven power generation system enters the working state; the generator has a set of wire groups connected to the power main control component. When the power main control component detects that the generator has current transmitted to it, it no longer uses the current transmitted from the battery, and switches to using the current transmitted by the generator; the current transmitted by the generator is processed by the power main control component and then transmitted to various electronic components, and the battery is charged; the power main control component has a set of wire groups connected to the external power port, and a set of wire groups is connected to the wireless charging module. When the battery is not used for a long time and the power is naturally lost, resulting in the inability to start the drive motor, the external power port can be connected to an external power supply or a wireless charging module to charge the battery and start the drive motor.
[0019] The invention has a simple and reasonable structure and a wide range of applications. It can well solve the problem of short use time when using a battery as a power source and frequent reliance on an external power source for charging; or the problem of using an external power source being restricted by site and consuming the power of the external power source, and can also provide current normally when there is a power outage outside.
[0020] 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.
