During the driving process of the hybrid vehicle, it is prone to start and stop repeatedly, which easily causes a large amount of heat to be generated in the stator. In addition, the high-speed rotation of the rotating motor also extremely easily causes a large amount of heat to be generated in the stator. If the increase in the stator temperature is not suppressed and the stator temperature in the motor rear cover is relatively high, it will generate thermal radiation to the electronic components installed on the motor rear cover. The electronic components installed on the motor rear cover mainly include a power module, a control module, a filtering module, etc. Among them, the power module is used to connect and drive the rotating motor, the control module is used to generate control signals and control the power module to further control the working mode of the rotating motor, and the filtering module prevents interference between the power module and the power grid of the motor vehicle wheels. However, it is inconvenient to install the power module, the control module, and the filtering module on the existing rotating motor. Moreover, the rotating motor also has many other components, which increases the difficulty of installing the power module, the control module, and the filtering module on the rotating motor, occupies a lot of time of the assembly personnel, and increases the assembly time of the rotating motor. Therefore, there is an urgent need for a rotating motor facilitating rapid installation of electronic components. Summary of the Invention

[0012] In addition, on the basis of the above technical solution, the present invention can be further improved and can also have the following additional technical features.

[0013] According to an embodiment of the present invention, one end of the connection structure I is connected to the motor rear cover, and the other end extends backward to form an extension end, and the power module is detachably installed on the extension ends of the number of connection structures I; one end of the connection structure II is connected to the motor rear cover, and the other end extends backward to form an extension end, and the control module is detachably installed on the extension ends of the number of connection structures II; one end of the connection structure III is connected to the motor rear cover, and the other end extends backward to form an extension end, and the filtering module is detachably installed on the extension ends of the number of connection structures III. In this embodiment, the power module, control module, and filtering module are all detachably installed on the motor rear cover, which is convenient for disassembling and assembling the power module, control module, and filtering module and is convenient for maintaining the rotating motor.

[0014] According to an embodiment of the present invention, a rotating motor facilitating quick installation of electronic components further includes:

[0015] A cooling fan, mounted on the rotating shaft, the cooling fan being located inside the cavity and on one side of the rotor;

[0016] A windshield structure, mounted between the electronic component and the motor rear cover, the edge of the windshield structure extending towards the circumferential side and covering the rear end of the motor rear cover, a gap being formed between the electronic component and the windshield structure to form a first cooling air inlet duct, and an axial air vent one being provided at the rear end of the windshield structure;

[0017] An axial air vent two communicating with the cavity is provided at the rear end of the motor rear cover, the axial air vent one communicating with the axial air vent two, a plurality of radial air outlets communicating with the cavity being spaced apart on the circumferential side of the motor rear cover, the radial air outlets being located on the circumferential side of the cooling fan. When the cooling fan rotates, the first cooling air inlet duct can suck air from the circumferential side to form a first cooling air flow, the first cooling air flow can flow through the axial air vent two into the cavity and can be discharged from the radial air outlets.

[0018] In this embodiment, by providing a windshield structure between the electronic component and the motor rear cover, a gap is formed between the electronic component and the windshield structure to form a first cooling air inlet duct. Thus, when the cooling fan rotates, the air outside the first cooling air inlet duct can enter the cavity of the motor rear cover through the first cooling air inlet duct for heat absorption; in addition, the windshield structure can also block the hot air formed after heat absorption and discharged from the radial air outlets of the motor rear cover, separating the air flow formed by the hot air discharged from the radial air outlets of the motor rear cover from the air flow formed by the air entering through the first cooling air inlet duct, avoiding the interference and mixing of the air flow formed by the hot air discharged from the radial air outlets of the motor rear cover and the air flow formed by the air entering through the first cooling air inlet duct to form turbulence, being able to reduce the intake air loss caused by turbulence, making the ventilation smoother, improving the cooling effect of the rotating motor, and further being beneficial to reducing the temperature of the motor rear cover, reducing the heat radiation generated by the motor rear cover on the electronic components mounted on the motor rear cover, and ensuring the normal operation of the electronic components mounted on the motor rear cover. Further, the windshield structure can also block part of the heat radiation generated by the motor rear cover towards the electronic component, further weakening the heat radiation received by the electronic component from the motor rear cover, being beneficial to avoiding the overheating of the electronic components mounted on the motor rear cover, and thus ensuring the normal operation of the electronic components.

[0019] According to one embodiment of the present invention, the edge of the windshield structure is inclined away from the motor rear cover and extends outward to form a side windshield. The edge of the windshield structure in this embodiment is inclined away from the motor rear cover and extends outward to form a side windshield, and the side windshield can increase the windshield range of the windshield structure in the circumferential direction, further improving the windshield structure to block the hot air formed by heat absorption and discharged from the radial air outlet of the motor rear cover, and further separate the airflow formed by the hot air discharged from the radial air outlet of the motor rear cover and the airflow formed by the air entering from the cooling air inlet duct 1, so as to avoid the airflow formed by the hot air discharged from the radial air outlet of the motor rear cover and the airflow formed by the air entering from the cooling air inlet duct 1 interfering with each other and forming turbulence, which can reduce the air intake loss caused by turbulence, make ventilation smoother, and improve the cooling effect of the rotating motor.

[0020] According to one embodiment of the present invention, the material of the windshield structure is a low thermal conductivity material. The material of the windshield structure in this embodiment is a low thermal conductivity material, which is conducive to reducing the conduction of heat radiation generated by the motor rear cover on the windshield structure, improving the effect of the windshield structure in blocking part of the heat radiation generated by the motor rear cover to the electronic components, further reducing the heat radiation of the motor rear cover to the electronic components, and helping to avoid the temperature of the electronic components installed on the motor rear cover being too high, thereby ensuring the normal operation of the electronic components.

[0021] According to one embodiment of the present invention, a closed-loop protrusion is connected to the front side of the windshield structure, and the closed-loop protrusion extends toward the motor back cover to form an extended end, and the extended end of the closed-loop protrusion is located on the outside of the second axial vent, and the extended end of the closed-loop protrusion fits and abuts against the motor back cover, and a groove body with one end blocked and the other end open is defined between the front side of the windshield structure, the closed-loop protrusion, and the motor back cover. The windshield structure in this embodiment is connected to a closed-loop protrusion on the side facing the motor back cover, and the closed-loop protrusion can fit and abut against the side of the motor back cover facing the windshield structure, so that a groove body with one end blocked and the other end open is defined between the front side of the windshield structure, the closed-loop protrusion, and the motor back cover, and air can enter the groove body, which is conducive to reducing the conduction of heat generated by the motor back cover to the windshield structure, and is conducive to reducing the temperature increase of electronic components installed on the motor back cover.

[0022] According to one embodiment of the present invention, a closed-loop protrusion is connected to the front side of the wind shield structure, and the closed-loop protrusion extends toward the motor rear cover to form an extended end. The extended end of the closed-loop protrusion is located on the outer side of the axial vent 2, and a receiving groove corresponding to the closed-loop protrusion is provided on the motor rear cover to accommodate the extended end of the closed-loop protrusion, and the extended end of the closed-loop protrusion is adapted to extend into the receiving groove.

[0023] In this embodiment, the extended end of the closed-loop protrusion is adapted to extend into the receiving groove, which is conducive to the closed-loop protrusion blocking between the windshield structure and the motor rear cover. An empty groove with one end open is defined among the front side of the windshield structure, the closed-loop protrusion and the motor rear cover. Air can enter the empty groove, which is conducive to reducing the heat generated by the motor rear cover from being conducted to the windshield structure, and is conducive to reducing the temperature rise of the electronic components installed on the motor rear cover. In addition, it is conducive to having a gap between the extended end of the closed-loop protrusion and the receiving groove, further reducing the energy conducted to the windshield structure through the closed-loop protrusion.

[0024] According to an embodiment of the present invention, the control module is installed at the rear end of the windshield structure, and the control module is located at the rear end of the power module. There is a gap between the control module and the power module to form a second cooling air inlet duct, and the second cooling air inlet duct communicates with the first axial ventilation opening. When the cooling fan rotates, the second cooling air inlet duct can suck air from the peripheral side to form a second cooling air flow.

[0025] In this embodiment, the control module is installed at the rear side of the motor rear cover. There is a gap between the control module and the power module to form a second cooling air inlet duct. When the cooling fan rotates, the second cooling air inlet duct sucks air from the peripheral side to form a second cooling air flow. The second cooling air flow sweeps across one side of the control module facing the second cooling air inlet duct and exchanges heat with the control module, thereby dissipating heat from the control module, which is conducive to improving the heat dissipation efficiency of the control module, avoiding the temperature of the control module from being too high and ensuring the normal operation of the control module. At the same time, the second cooling air flow sweeps across one side of the power module facing the second cooling air inlet duct and exchanges heat with the power module, thereby dissipating heat from the power module, which is conducive to improving the heat dissipation efficiency of the power module.

[0026] According to an embodiment of the present invention, the filtering module is installed at the rear end of the windshield structure and is located outside the power module in the radial direction towards the rotating shaft. There is a gap between the filtering module and the windshield structure to form a third cooling air inlet duct, and the third cooling air inlet duct communicates with the first axial ventilation opening. When the cooling fan rotates, the third cooling air inlet duct can suck air from the peripheral side to form a third cooling air flow.

[0027] In this embodiment, the filtering module is installed at the rear end of the windshield structure and is located outside the power module in the radial direction towards the rotating shaft. There is a gap between the filtering module and the windshield structure to form a third cooling air inlet duct. When the cooling fan rotates, the third cooling air inlet duct sucks air from the peripheral side to form a third cooling air flow. The third cooling air flow sweeps across one side of the filtering module facing the windshield structure and exchanges heat with the filtering module, thereby dissipating heat from the filtering module, which is conducive to improving the heat dissipation efficiency of the filtering module, avoiding the temperature of the filtering module from being too high and ensuring the normal operation of the filtering module.
