[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] Please refer to Figures 1 to 6 A specific embodiment of a polymerization power generation unit as shown.

[0042] As Figure 1 and Figure 2 shown, in this embodiment, the polymerization power generation unit includes a housing 1, a junction box 11 is provided at the top of the housing 1, a central shaft 2 longitudinally penetrates into the housing 1 and extends outward at the centers of both ends of the housing 1, a power rotor 3 sleeved on the central shaft 2, a power stator 4 sleeved outside the power rotor 3 and fixedly connected to the housing 1, a power generation rotor 5 sleeved on the central shaft 2 and connected in series with the power rotor 3, a power generation stator 6 sleeved outside the power generation rotor 5 and fixedly connected to the housing 1. The central shaft 2 is fixedly connected to the power rotor 3 and the power generation rotor 5 and is arranged at the center inside the housing 1. The junction box 11 is connected to the power stator 4. The battery passes current into the power stator 4 through the junction box 11. The power stator 4 is energized to generate a rotating magnetic field to make the power rotor 3 rotate. The rotation of the power rotor 3 drives the central shaft 2 to rotate. The rotation of the central shaft 2 drives the power generation rotor 5 to rotate to generate mechanical energy. The rotation of the power generation rotor 5 performs electromagnetic cutting with the power generation stator 6 to convert mechanical energy into electrical energy. The junction box 11 is connected to the power generation stator 6 for transmitting electricity to the battery, and the battery then transmits electricity to the power stator 4 to realize the utilization of surplus electricity and increase the endurance.

[0043] Specifically, as Figure 1 and Figure 2As shown, covers 7 are respectively provided at both ends of the housing 1 and are fixedly connected by bolts. A fan mounting portion 71 is provided on the cover 7 at one end for mounting a fan. A plurality of heat sinks are provided on the outer peripheral wall of the housing 1 for heat dissipation. A support 8 is provided on the outer peripheral wall of the housing 1 for supporting and fixing the housing 1. The central shaft 2 passes through the centers of the covers 7 at both ends of the housing 1. Pin slots 21 are provided at both ends of the central shaft 2. Preferably, they are set as square anti-slip pin slots 21. The power rotor 3 and the generator rotor 5 are sleeved on the central shaft 2 in series. The battery supplies power to the power stator 4 fixed in the housing 1. When the power stator 4 is powered on, a rotating magnetic field is generated to make the power rotor 3 rotate to generate torque, converting electrical energy into mechanical energy. The rotation of the power rotor 3 drives the central shaft 2 to rotate, and the generator rotor 5 fixedly connected to the central shaft 2 rotates accordingly. The generator rotor 5 rotates in the generator stator 6 to generate an induced electromotive force, which is connected to the junction box 11 through a wire and outputs electrical energy through an external circuit. The voltage is adjusted by a transformer, and the current is transmitted to the battery. The battery then transmits the electricity to the power stator 4 through the wire connected to the junction box 11, and converts the newly generated electrical energy into mechanical energy again, realizing the recycling of the remaining electricity of the battery car and increasing the endurance of the electric vehicle.

[0044] Specifically, as Figures 3 to 5 shown, a bushing 31 is provided at one end of the power rotor 3. The power rotor 3 is sleeved on the central shaft 2 based on the bushing 31 for driving the central shaft 2 to rotate. The rotation of the central shaft 2 drives the generator rotor 5 to rotate and interact with the generator stator 6 to generate electricity, converting the mechanical energy of the power rotor 3 into electrical energy.

[0045] Specifically, as Figure 4 and Figure 5 shown, the power stator 4 includes a power stator core 41 fixedly installed in the housing 1, a power stator winding 42 wound around the inner peripheral wall of the power stator core 41, and a first circuit board (not shown in the figure) installed on the power stator core 41. The power stator winding 42 is composed of coils wound by a plurality of copper wires. The coils are wound around the power stator core 41. The power stator winding 42 is connected to the first circuit board and powered on. The current passes through the power stator winding 42 to generate a rotating magnetic field. The power rotor 3 is rotated by the torque generated by the rotating magnetic field, converting electrical energy into mechanical energy to drive the central shaft 2 to rotate. The copper wires are wound around the power stator core 41 to form the power stator winding 42, which is electrically connected to the junction box 11 through the first circuit board. The battery is powered on through the circuit in the junction box 11 to make the power stator 4 produce a rotating magnetic field.

[0046] Specifically, as Figures 2 to 6As shown in the figure, a number of copper coils 51 are wound axially around the power generation rotor 5. A number of coil fixing plates 52 are provided on both sides of the power generation rotor 5 to fix the copper coils 51. Insulating ceramic sheets 53 are provided at both ends of the power generation rotor 5. The wound copper coils 51 form a conductor of a closed circuit, and cut the magnetic induction lines in a magnetic field to generate an induced current.

[0047] Specifically, the power generation stator 6 includes a power generation stator core 61 fixedly installed in the housing 1, a power generation stator winding 62 wound around the inner peripheral wall of the power generation stator core 61, and a second circuit board (not shown in the figure) installed on the power generation stator core 61. The power generation stator winding 62 is composed of coils wound by a number of copper wires. The coils are wound around the power generation stator core 61. The central shaft 2 drives the power generation rotor 5 to rotate, causing an induced electromotive force (i.e., induced voltage) to be generated in the coils of the power generation stator 6. The induced electromotive force then outputs electrical energy through a circuit to the junction box 11 and is then transmitted to a transformer and finally stored in a battery, converting mechanical energy into electrical energy. The battery then supplies power to the power unit, and the power unit also serves as a power source to drive the electric vehicle to operate.

[0048] It can be understood that the central shaft 2 is fixed by using square anti-slip pins. After the power rotor 3 and the power generation rotor 5 are sleeved on the central shaft 2, they are fixed on both sides with thickened spring cards respectively, so that they cannot move axially on both sides within the shaft sleeves 31 of the power rotor 3 and the power generation rotor 5. There is an insulating ceramic sheet 53 between the power generation rotor 5 and the power rotor 3 to isolate the electromagnetic field. The outer diameter of the power rotor 3 is 120 mm, the length of the power rotor 3 is 165 mm, the outer diameter of the power generation rotor 5 is 120 mm, the length of the power generation rotor 5 is 165 mm, the distance between the power rotor 3 and the power generation stator 4 is set to 0.2 mm, and the distance between the power generation rotor 5 and the power generation stator 6 is set to 0.2 mm.

[0049] This combined power generation unit can solve the problem that the way of a single generator with a single shaft being driven to rotate and output power in the traditional generator field cannot meet the current market demand. Currently, when the battery of an electric vehicle runs out of power, it cannot be used continuously. Usually, it needs to be charged for a long time to ride for a short time. Electric vehicles dare not turn on the air conditioner in winter and dare not waste electricity for fear of breaking down on the highway and cannot be used as one wishes. This combined power generation unit solves the problem of the short continuous endurance of existing electric vehicles.

[0050] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modifications, equivalent changes or decorations made by those skilled in the art using the disclosed technical content all fall within the protection scope of the present invention.
