Description

Technical Field

[0001] This invention relates to the field of integrated motor technology, specifically to an integrated motor for new energy vehicles and its assembly method. Background Technology

[0002] The integrated motor in new energy vehicles is an advanced technology in the drive system of new energy vehicles. It highly integrates important components such as motor, controller, and reducer to form a compact, efficient, and high-performance power unit. The highly integrated power system can effectively reduce the number of parts, reduce size and weight, and improve energy utilization and vehicle range.

[0003] Furthermore, deep integration has driven the previously independent and dispersed powertrain control modules toward a centralized convergence of power domain controllers. This has improved the power density and system efficiency of integrated motors, while the simplified production process and reduced number of parts have directly reduced manufacturing and maintenance costs.

[0004] Existing integrated motors generate resonance and noise during operation. These vibrations and noises form high-frequency noise that enters the human ear. During long-term driving, this can lead to driver fatigue and anxiety, thereby affecting the driver's reaction speed and judgment. Therefore, soundproof covers are often installed on the outside of the motor. However, soundproof covers are not conducive to motor heat dissipation, which increases the motor's failure rate and raises safety risks. Therefore, this paper proposes an integrated motor for new energy vehicles and its assembly method to address the above problems. Summary of the Invention

[0011] As a further optimization of the present invention, there are: two inter-frame threaded holes, two fixing bolts, and one-to-one correspondence between the inter-frame threaded holes and the fixing bolts; two airbag blocks, which are parallel to each other; two threaded grooved fixing discs, which are parallel to each other; and the airbag blocks and the threaded grooved fixing discs are on the same axis.

[0012] As a further optimization of the present invention, wherein: a sliding rod is slidably connected to the inner side of the bottom sliding groove of the box, the central axis of the sound-insulating hollow column formed is on the same straight line as the central axis of the hollow column inside the box, a sliding rod is slidably connected to the inner side of the first column sliding groove, a sliding rod is slidably connected to the inner side of the second column sliding groove, and the upper end of the hollow column inside the box is attached to the bottom end of the protective strip.

[0013] As a further optimization of the present invention, the following features are provided: the circular opening of the bottom plate and the hollow column inside the box are on the same axis; a sliding rod is slidably connected to the inner side of the sliding groove between the bottom plates; a water-absorbing expansion column is slidably connected to the inner side of the hollow tube with square groove; the outer side of the hollow tube with square groove is in contact with the inner side of the lower half of the tube; two sliding grooves are provided in the bottom plate, and the two sliding grooves are symmetrically distributed in front and behind on the inner side of the hollow bottom plate; a number of ball bearings are provided, and the ball bearings are evenly and equidistantly distributed in the inner side of the sliding grooves in the bottom plate.

[0014] As a further optimization of the present invention, wherein: a hollow tube with a square groove is slidably connected to the inner side of the lower half of the block, a sliding connecting rod is slidably connected to the inner side of the limiting hollow tube, two limiting hollow tubes are provided, the two limiting hollow tubes are symmetrically distributed front and back on one side of the sliding block, and two limiting square strips are provided, the two limiting square strips are symmetrically distributed front and back on one side of the sliding block.

[0015] As a further optimization of the present invention, there are two connecting rod assemblies, which are symmetrically distributed on one side of the sliding assembly. One end of the fixed shaft is fixedly connected to a hollow base plate, and one end of the connecting spring is fixedly connected to the hollow base plate. The included angle between the connecting rod on the plate and the rotating plate is 90°.

[0016] As a further optimization of the present invention, wherein: S1: Connection and installation of the frame assembly, shock-absorbing airbag assembly and inner box assembly: The support square plate is placed on the upper end of the soundproof hollow column, so that the inner hollow column is clamped on the inner side of the soundproof hollow column and fits against the lower end of the first column sliding groove. By screwing, the fixing bolt is entered into the inner side of the inter-frame threaded hole and the second threaded groove between the blocks, so that the fixing bolt is simultaneously spirally connected to the hole frame and the support block under the plate. After the grooved bolt passes through the first threaded groove between the blocks, it is simultaneously spirally connected to the airbag block and the threaded grooved fixing plate, and the grooved bolt is spirally connected to the inner threaded column of the box;

[0017] S2: Noise Reduction Optimization Components reduce noise and cool the motor: The airbag shock absorber box is placed inside the outer box assembly, and the inner box assembly is placed inside the airbag shock absorber box, so that the airbag shock absorber box wraps around the inner box assembly. At this time, the high-frequency noise generated by the motor is transmitted to the airbag shock absorber box through the frame assembly, shock absorber airbag assembly and inner box assembly. The inert gas filling the inside of 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. The sliding connecting rod is moved through the connecting rod on the plate and the transmission connecting rod. The sliding connecting rod moves a certain distance in the limit hollow tube and pushes the sliding assembly to move. At this time, the upper end of the sliding block no longer blocks the round opening of the bottom plate, and one end of the sliding rod no longer contacts the stop switch on the fan power unit. At this time, the fan power unit starts and cools the motor with wind power.

[0018] S3: Waterproofing measures for noise reduction and optimization components when the car passes through waterlogged sections: When water droplets enter the hollow tube with square groove through the half-pipe square groove and the pipe square groove, the water-absorbing expansion column will absorb water and expand, pushing the sliding component to move. When the sliding component moves a certain distance, the sliding rod will press the stop switch on the fan power unit, causing the fan power unit to stop running. At the same time, the sliding block will block the round opening of the bottom plate to prevent water droplets from entering the car through the bottom plate component.

[0019] S4: Balanced control of base plate assembly, sliding assembly and connecting rod assembly: When the car speed is too high, the motor speed will be too high, resulting in a sharp increase in temperature. At the same time, the wind resistance of the connecting rod assembly will increase, and the force transmitted from the rotating plate to the sliding connecting rod through the plate connecting rod and the transmission connecting rod will increase. The force generated by the sliding connecting rod on the sliding assembly is greater than the force generated by the water absorption expansion column deformation on the sliding assembly. At this time, the sliding connecting rod will push the sliding assembly to move, so that the upper end of the sliding block no longer blocks the round opening of the base plate, and one end of the sliding rod no longer contacts the stop switch on the fan power unit, so that the fan power unit restarts. The noise reduction optimization component will still provide wind cooling for the motor in the water environment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the noise reduction optimization component can guide the transmission path of high-frequency noise generated by the motor, effectively absorb and isolate the high-frequency noise generated during motor operation, 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 environment, thus affecting the driving state.

[0022] 2. In this invention, the self-starting fan power device in the inner box assembly achieves effective heat dissipation. By cooling with airflow and forcibly carrying away heat, the motor is prevented from overheating due to the sound insulation equipment, and the motor is kept running at a suitable operating temperature. This is more efficient than natural cooling, and can significantly improve the thermal stability and reliability of the motor, especially under high load or long-term operation.

[0023] 3. In this invention, the base plate assembly, sliding assembly, and connecting rod assembly enable the device to have excellent intelligent environmental adaptability. When a car passes through a flooded section of road, it can automatically activate waterproof measures to close any possible water ingress channels and protect the motor from water damage. When the motor speed is too fast and the temperature rises abnormally, it can also automatically activate the heat dissipation device to achieve rapid and effective cooling.

This design can strengthen the mutual support between components and facilitate the operation of the device.

[0046] As a further implementation of this solution, the linkage assembly 49 includes a fixed shaft 491, a rotating plate 492 rotatably connected to the outside of the fixed shaft 491, a connecting spring 493 fixedly connected to one side of the rotating plate 492, a plate connecting rod 494 fixedly connected to one side of the rotating plate 492, a transmission connecting rod 495 rotatably connected to the outside of the plate connecting rod 494, and a sliding connecting rod 496 rotatably connected to the outside of the transmission connecting rod 495.

This design improves the fit between the device components and avoids obstruction between components during device operation.

[0049] As a further implementation of this solution, the circular opening 472 of the bottom plate and the hollow column 437 inside the box are on the same axis. A sliding rod 482 is slidably connected to the inner side of the sliding groove 473 between the bottom plates.

[0052] S1: Connection and installation of frame assembly 41, shock-absorbing airbag assembly 42 and inner box assembly 43: Place the support square plate 414 on the upper end of the sound insulation hollow column 435, so that the inner hollow column 437 is locked inside the sound insulation hollow column 435 and fits against the lower end of the first column sliding groove 436. Tighten the fixing bolt 425 into the inner side of the frame threaded hole 424 and the second threaded groove 419 between the blocks, so that the fixing bolt 425 is simultaneously screwed to the hole frame 423 and the lower support block 417.

[0053] S2: Noise reduction and optimization component 4 reduces noise and cools the motor 3: The airbag shock absorber 44 is placed inside the outer casing component 45, and the inner casing component 43 is placed inside the airbag shock absorber 44, so that the airbag shock absorber 44 encloses the inner casing component 43. At this time, the high-frequency noise generated by the motor 3 is transmitted to the airbag shock absorber 44 through the frame component 41, the shock-absorbing airbag component 42, and the inner casing component 43. The inert gas filling the inside of the airbag shock absorber 44 will reduce the transmission of noise, while the rotation... When the car moves, the plate 492 is displaced by wind resistance. The sliding link 496 moves through the plate link 494 and the transmission link 495. The sliding link 496 moves a certain distance in the limiting hollow tube 486 and pushes the sliding component 48 to move. At this time, the upper end of the sliding block 481 no longer blocks the bottom plate round opening 472, and one end of the sliding rod 482 no longer contacts the stop switch on the fan power unit 439. At this time, the fan power unit 439 starts and cools the motor 3 with wind.

[0054] S3: Waterproofing measures of noise reduction and optimization component 4 when the car passes through a flooded section: When water droplets enter the hollow tube 474 with square groove through the semi-pipe square groove 484 and the pipe square groove 475, the water absorption expansion column 485 will absorb water and expand, pushing the sliding component 48 to move. When the sliding component 48 moves a certain distance, the sliding rod 482 squeezes the stop switch on the fan power unit 439, causing the fan power unit 439 to stop running. At the same time, the sliding block 481 will block the bottom plate round opening 472 to prevent water droplets from entering the car through the bottom plate component 47.

[0055] S4: Balanced control of base plate assembly 47, sliding assembly 48 and connecting rod assembly 49: When the car speed is too fast, the motor 3 will rotate too fast, causing the temperature to rise sharply. At the same time, the wind resistance of the connecting rod assembly 49 increases, which increases 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. 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 round opening 472 of the base plate, and one end of the sliding rod 482 no longer contacts the stop switch on the fan power unit 439, so that the fan power unit 439 restarts. The noise reduction optimization component 4 will still provide wind cooling for the motor 3 in the water environment.

10. An assembly method for an integrated motor based on new energy vehicles as described in claim 9, characterized in that: S1: Connection and installation of frame assembly (41), shock-absorbing airbag assembly (42) and inner box assembly (43): Place the support square plate (414) on the upper end of the sound insulation hollow column (435), so that the inner hollow column (437) is clamped on the inner side of the sound insulation hollow column (435) and fits against the lower end of the first column sliding groove (436). By screwing, the fixing bolt (425) enters the inner side of the inter-frame threaded hole (424) and the second threaded groove (419) between the blocks, so that the fixing bolt (425) is simultaneously screwed to the opening frame (423) and the lower support block (417). The grooved bolt (421) passes through the first threaded groove (418) between the blocks and is simultaneously screwed to the airbag block (426) and the threaded grooved fixing plate (427). The grooved bolt (421) is screwed to the inner threaded column (432). S2: Noise reduction optimization component (4) reduces noise and cools down the motor (3): The airbag shock absorber (44) is placed inside the outer casing component (45), and the inner casing component (43) is placed inside the airbag shock absorber (44), so that the airbag shock absorber (44) covers the inner casing component (43). At this time, the high-frequency noise generated by the motor (3) is transmitted to the airbag shock absorber (44) through the frame component (41), the shock absorber airbag component (42) and the inner casing component (43). The inert gas filling the inside of the airbag shock absorber (44) will reduce the propagation of noise. When the car moves, the rotating plate (492) is displaced by wind resistance. The sliding connecting rod (496) moves through the connecting rod (494) and the transmission connecting rod (495) on the plate. The sliding connecting rod (496) moves a certain distance in the limiting hollow tube (486) and pushes the sliding component (48) to move. At this time, the upper end of the sliding block (481) no longer blocks the bottom plate round 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) starts and cools the motor (3) with wind. S3: Waterproofing measures of the noise reduction optimization component (4) when the car passes through the water-filled section: When water droplets enter the hollow tube (474) with square groove through the half-pipe square groove (484) and the pipe square groove (475), the water absorption expansion column (485) will absorb water and expand, pushing the sliding component (48) to move. When the sliding component (48) moves a certain distance, the sliding rod (482) squeezes the stop switch on the fan power unit (439), causing the fan power unit (439) to stop running. At the same time, the sliding block (481) will block the bottom plate round opening (472) to prevent water droplets from entering the car through the bottom plate component (47). S4: Balanced control of base plate assembly (47), sliding assembly (48) and linkage assembly (49): When the car speed is too fast, the motor (3) speed will be too high, resulting in a sharp increase in temperature. At the same time, the wind resistance of the linkage assembly (49) will increase, and the force transmitted from the rotating plate (492) to the sliding linkage (496) through the plate linkage (494) and the transmission linkage (495) will increase. The force generated by the sliding linkage (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 linkage (496) will push the sliding assembly (48) to move, so that the upper end of the sliding block (481) will no longer block the round opening (472) of the base plate, and one end of the sliding rod (482) will no longer contact the stop switch on the fan power unit (439), so that the fan power unit (439) will start again. The noise reduction optimization component (4) will still cool the motor (3) with wind in the water environment.
