Hybrid power systems are commonly applied to the field of automobiles, and the hybrid power systems are used for driving automobiles to run so as to achieve the purposes of saving energy and reducing environmental pollution. However, the existing hybrid system still has a lot of problems in the actual use process.

Further, the hybrid system includes a controller 500P and a mounting bracket 600P, the mounting bracket 600P is mounted on one side of the engine 100P for carrying the controller 500P, the controller 500P is electrically connected to the generator 200P by a plurality of high voltage wires, the controller 500P is capable of providing various operation data of the engine 100P and the generator 200P and providing protection functions, such as oil temperature, water temperature and overspeed protection of the engine 100P; the power display and power protection of the generator 200P, etc. In the operation process, the generator 200P and the controller 500P do work for a long time, the temperature is continuously increased, and in order to ensure the normal operation of the controller 500P and the generator 200P, a special cooling pipeline needs to be configured to perform heat dissipation and cooling treatment on the controller 500P and the generator 200P. However, due to the poor structural integration of the conventional hybrid power system, the distribution of the generator 200P and the controller 500P is scattered, so that the controller 500P and the generator 200P are provided with independent cooling pipelines, which are independent of each other, thereby resulting in a large volume and a heavy overall weight of the conventional hybrid power system. In addition, the flywheel 300P, the flywheel housing 400P, and the generator 200P are sequentially disposed at one side of the engine 100P in a horizontal direction, resulting in a long length of the hybrid system and a large space required for installation. Also, the mounting bracket 600P for carrying the controller 500P occupies a large space, which is also disadvantageous to the miniaturization of the conventional hybrid system. In addition, the controller 500P is placed on the surface of the mounting bracket 600P, and the periphery is not fixed or protected, so that the controller is easy to slide or even separate other components during the process of carrying or mounting the hybrid power system, and an operator is injured by mistake, so that the conventional hybrid power system has a great potential safety hazard. In addition, the high-voltage wires connecting the controller 500P and the generator 200P are exposed to the outside, and are easily worn by surrounding components during subsequent assembly and use, so that the high-voltage wires are damaged and leak electricity, and the safety performance of the conventional hybrid power system is reduced.

Therefore, it is necessary to improve the structure of the existing hybrid system to increase the degree of integration of the hybrid system.

In accordance with a preferred embodiment of the present invention, in the above method, the generator stator 31 of the power assembly 30 is fixed to the extension 111 of the flywheel housing main body 11 of the integrated flywheel housing 10 by interference fit.

In accordance with a preferred embodiment of the present invention, in the above method, the integrated rotor 32 of the power assembly 30 is rotatably retained in the movable passage 310 of the generator stator 31 while the integrated rotor 32 is mounted to the engine 200. Further, in the above method, the integrated rotor 32 and the generator stator 31 of the power assembly 30 are kept coaxial with the crankshaft of the engine 200, so that the mechanical energy generated by the engine 200 is smoothly transmitted to the rotor body 323 during the subsequent use process, and the stability of the hybrid system 100 is guaranteed.

According to a preferred embodiment of the present invention, in the above method, further comprising the steps of: the closure element 40 is removably mounted to the extension 111 of the flywheel housing body 11 of the integrated flywheel housing 10.

According to a preferred embodiment of the present invention, in the above method, further comprising the steps of: a first cooling channel and a second cooling channel of the first cooling channel and the second cooling channel of the second cooling channel are respectively surrounded on the generator stator 31 of the power assembly 30 and the controller 20, wherein the first cooling channel and the second cooling channel of the first cooling channel are communicated with a cooling liquid inlet 501 and a cooling liquid outlet 502. A coolant enters the first cooling channel of the first cooling pipe and the second cooling channel of the second cooling pipe from the coolant inlet 501, and the coolant flowing in the first cooling pipe and the second cooling pipe absorbs heat generated by the generator stator 31 and the controller 20 during operation, respectively, so as to ensure that the temperatures of the power assembly 30 and the controller 20 can be within a normal range at the same time. The cooling liquid in the first cooling pipe and the second cooling pipe continuously flows out from the cooling liquid outlet 502 of the liquid outlet pipe 52 to take away the heat of the controller 20 and the power assembly 30. Preferably, the first cooling channel spirally surrounds the generator stator 31 of the power assembly 30.
