The highly integrated power system can effectively reduce the number of components, reduce volume and weight, and improve energy utilization and vehicle endurance.

[0003] In addition, deep integration has driven the originally independent and scattered powertrain control modules to move towards a centralized integration of the power domain controller, thereby improving the power density and system efficiency of the integrated motor.

At this time, the high-frequency noise generated by the motor is transmitted to the airbag shock absorber box through the frame component, the shock-absorbing airbag component and the inner box component. The inert gas filled inside the airbag shock absorber box will reduce the propagation of noise. At the same time, the rotating plate is displaced by wind resistance when the car moves, and the sliding connecting rod is moved through the connecting rod on the plate and the transmission connecting rod.

At the same time, the wind resistance of the connecting rod assembly will increase, which will increase the force transmitted to the sliding link by the rotating plate through the plate link and the transfer link. The force generated by the sliding link on the sliding assembly is greater than the force generated by the deformation of the water absorption expansion column on the sliding assembly. At this time, the sliding link will push the sliding assembly to move, so that the upper end of the sliding block no longer blocks the circular opening of the base plate, and one end of the sliding rod no longer contacts the stop switch on the fan power device, so that the fan power device is started again, and the noise reduction optimization component will still use wind power to cool the motor in a wading environment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the noise reduction optimization component is set to guide the transmission path of the high-frequency noise generated by the motor, effectively absorb and isolate the high-frequency noise generated when the motor is running, and achieve noise attenuation by improving the transmission path, which significantly improves the acoustic comfort in the cockpit and avoids fatigue and anxiety of the driver due to long-term exposure to high-frequency noise, which affects the driving state.

[0017] 2. In the present invention, an effective heat dissipation function is achieved by the self-starting fan power device in the inner box assembly. The heat is removed by forced convection through wind cooling, avoiding overheating of the motor due to sound insulation equipment, and keeping the motor running at a suitable operating temperature. Compared with natural cooling, it is more efficient, especially under high load or long-term operation, and can significantly improve the thermal stability and reliability of the motor.

[0018] 3. In the present invention, by providing the bottom plate assembly, sliding assembly and connecting rod assembly, the device has excellent intelligent environmental adaptability. When the car passes through a wading section, it can automatically start the waterproof measures to close possible water inlet channels and protect the motor from moisture. When the motor speed is too fast and the temperature rises abnormally, the heat dissipation device can be automatically operated to achieve rapid and effective cooling.

The integrated motor for new energy vehicles and the assembly method thereof according to any one of claims 1 to 9, characterized in that: S1: Connection and installation of the frame assembly (41), the shock-absorbing airbag assembly (42) and the inner box assembly (43): Place the supporting square plate (414) on the upper end of the sound-insulating hollow column (435), so that the hollow column (437) in the box is clamped on the inner side of the sound-insulating hollow column (435) and fits with the lower end of the first inter-column sliding groove (436), and screw the fixing bolt (425) into the inner side of the inter-frame threaded hole (424) and the second inter-block threaded groove (419), so that the fixing bolt (425) is screwed together with the perforated frame (423) and the support block (417) under the plate at the same time, and the slotted bolt (421) is screwed together with the airbag block (426) and the screwed fixing plate (427) after passing through the first inter-block threaded groove (418), and the slotted bolt (421) is screwed together with the threaded column (432) in the box; S2: The noise reduction optimization component (4) reduces noise and cools the motor (3): the airbag shock-absorbing box (44) is placed inside the outer box component (45), and the inner box component (43) is placed inside the airbag shock-absorbing box (44), so that the airbag shock-absorbing box (44) wraps the inner box component (43). At this time, the high-frequency noise generated by the operation of the motor (3) is transmitted to the airbag shock-absorbing box (44) through the frame component (41), the shock-absorbing airbag component (42) and the inner box component (43). The inert gas filled inside the airbag shock-absorbing box (44) will reduce the propagation of noise, and at the same time When the automobile moves, the rotating plate (492) is displaced by wind resistance, and the sliding connecting rod (496) is moved through the connecting rod (494) on the plate and the transmission connecting rod (495). The sliding connecting rod (496) moves a certain distance in the limiting hollow tube (486) to push the sliding assembly (48) to move. At this time, the upper end of the sliding block (481) no longer blocks the bottom plate circular opening (472), and one end of the sliding rod (482) no longer contacts the stop switch on the fan power device (439). At this time, the fan power device (439) is started to cool the motor (3) by wind. S3: Waterproof measures for the noise reduction optimization component (4) when the vehicle passes through a wading section: When water drops enter the hollow tube with square grooves (474) through the square grooves (484) between the half tubes and the square grooves (475) between the tubes, the water absorption expansion column (485) absorbs water and expands, pushing the sliding component (48) to move. When the sliding component (48) moves a certain distance, the sliding rod (482) presses the stop switch on the fan power device (439), so that the fan power device (439) stops running. At the same time, the sliding block (481) blocks the bottom plate circular opening (472) to prevent water drops from entering the interior of the vehicle through the bottom plate component (47); S4: Balanced regulation of the bottom plate assembly (47), the sliding assembly (48) and the connecting rod assembly (49): When the speed of the vehicle is too fast, the rotation speed of the motor (3) will be too high, resulting in a sharp increase in temperature. At the same time, the wind resistance of the connecting rod assembly (49) will increase, so that the force transmitted from the rotating plate (492) to the sliding connecting rod (496) through the plate connecting rod (494) and the transmission connecting rod (495) will increase. The force generated by the sliding connecting rod (496) on the sliding assembly (48) is greater than the force generated by the deformation of the water absorption expansion column (485) on the sliding assembly (48). At this time, the sliding connecting rod (496) will push the sliding assembly (48) to move, so that the upper end of the sliding block (481) no longer blocks the bottom plate circular opening (472), and one end of the sliding rod (482) no longer contacts the stop switch on the fan power device (439), so that the fan power device (439) is started again, and the noise reduction optimization component (4) will still perform wind cooling on the motor (3) in the wading environment.
