Description

Technical Field

[0001] This invention belongs to the field of drive motor technology and relates to a low-noise drive motor. Background Technology

[0002] New energy vehicle motors are devices that convert electrical energy into mechanical energy. They convert electrical energy into driving force through electromagnetic induction or magnetic field to provide power output for the vehicle. They also support functions such as energy recovery and system coordination control, and serve to replace traditional fuel engines, directly driving the wheels or transmission system to meet the basic driving needs of the vehicle, such as acceleration, deceleration, and hill climbing.

[0003] As a core component of the power system, the drive motor of new energy vehicles requires its bearings to withstand high-frequency alternating loads and wide temperature range conditions. After long-term operation, they are prone to damage due to lubrication failure, assembly errors, or material fatigue. When the bearing is damaged, the peeling of the bearing rolling elements or the cracking of the raceway will destroy the radial constraint of the rotor, resulting in eccentric rotation. This can easily cause periodic friction between the stator and the rotor core, leading to winding insulation damage, short circuits, or even burnout. In addition, the abnormal vibration generated by the rotation and oscillation is transmitted to components such as the reducer and coupling, accelerating gear wear or breakage and affecting power transmission efficiency. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the bearings of the drive motor of a new energy vehicle, as a core component of the power system, need to withstand high-frequency alternating loads and wide temperature range conditions. After long-term operation, they are prone to damage due to lubrication failure, assembly errors, or material fatigue. When the bearing is damaged, the peeling of the bearing rolling elements or the cracking of the raceway will destroy the radial constraint of the rotor, resulting in eccentric rotation. This can easily cause periodic friction between the stator and the rotor core, leading to winding insulation damage, short circuits, or even burnout. In addition, the abnormal vibration generated by the rotation and oscillation is transmitted to components such as the reducer and coupling, accelerating gear wear or breakage and affecting power transmission efficiency.

A plurality of telescopic rods are fixedly connected to the edge of the first mounting plate away from the mounting legs, and a second mounting plate is fixedly connected to the moving end of the telescopic rod.

[0006] A straightening assembly is disposed on a first mounting plate and a second mounting plate, the straightening assembly being used in conjunction with a rotor.

[0007] The correction assembly includes a transmission box fixedly connected to a first mounting plate. A transmission push plate is slidably connected inside the transmission box. An arc-shaped plate is fixedly connected to one end of the transmission push plate away from the inside of the transmission box. The end of the arc-shaped plate away from the transmission push plate is close to the outer wall of the rotor. A cavity is formed inside the end of the transmission push plate away from the arc-shaped plate. A rack is fixedly connected inside the cavity. A mounting frame is fixedly connected inside the transmission box, and a first transmission rod is rotatably connected to the other end of the mounting frame. A transmission gear that meshes with the rack is fixedly connected to the middle of the first transmission rod. One end of the first transmission rod passes through the inside of the transmission box. The parts on the first mounting plate and the second mounting plate are identical.

[0008] The correction assembly further includes a second transmission rod and a support plate. The second transmission rod is rotatably mounted on the first mounting plate, and the support plate is rotatably mounted on the first mounting plate. A first pulley assembly is provided between one end of the second transmission rod and the first transmission rod. A threaded cylinder is rotatably passed through one end of the support plate. A bevel gear assembly is driven between one end of the threaded cylinder and the second transmission rod. A screw is threadedly connected to the end of the threaded cylinder away from the bevel gear assembly, and the other end of the screw is connected to an arc-shaped push block that is slidably connected to the first mounting plate. The parts on the first mounting plate and the second mounting plate are identical.

[0009] The correction assembly also includes a rotating ring and rotating rods. The rotating ring is rotatably mounted on the first mounting plate. A connecting plate is fixed to one side of the edge of the rotating ring. The connecting plate abuts against one end of the arc-shaped push block. Multiple sets of square frames are rotatably mounted at equal intervals inside the rotating ring. Multiple sets of rotating rods are also provided. These multiple sets of rotating rods are rotatably mounted at equal intervals on the edge of the first mounting plate. One end of the rotating rod slides through the inside of the square frame and is fixed to a connecting frame. A rotating shaft is rotatably connected to the end of the connecting frame away from the rotating rod. A correction ball is fixed to the middle of the rotating shaft. One side of the outer wall of the correction ball is close to the outer wall of the rotor. A lubrication assembly is provided inside the connecting frame. The parts on the first mounting plate and the second mounting plate are identical.

[0010] The lubrication assembly includes a third transmission rod and an oil tank. The third transmission rod passes through the inner wall of the connecting frame and is connected to a second pulley set between one end of the rotating shaft. A support rod is rotatably connected to the middle of the third transmission rod, and the other end of the support rod is fixed to the bottom wall of the connecting frame. A cam is fixed to the end of the third transmission rod away from the second pulley set. The oil tank is installed on the bottom wall inside the connecting frame. A press pump is installed at one end of the oil tank. An arc-shaped plate opposite to the position of the cam is fixed to the end of the press pump away from the oil tank. An infusion pipe is connected to the oil outlet of the press pump.

[0011] The lubrication assembly also includes a support housing, which is fixed to one end of the connecting frame near the correction ball. A sponge layer is fixed to the side of the support housing near the correction ball. The end of the infusion tube away from the press pump extends into the interior of the sponge layer and is connected to a nozzle. Multiple flow holes are formed around the outer wall of the nozzle.

[0012] A push-button alarm is installed in the center of the arc-shaped plate, and a touch plate is slidably connected inside the arc-shaped plate. A return spring is provided between the touch plate and the four corners of the arc-shaped plate.

[0013] A corrugated sleeve is fitted between the first mounting plate and the second mounting plate, and one end of the corrugated sleeve is fixed to the edge of the first mounting plate by multiple sets of bolts.

[0014] The base is also fixed to multiple sets of mounting blocks by multiple sets of bolts, and the noise reduction frame is fixed to the multiple sets of mounting blocks together.

[0015] The noise reduction frame has three layers inside. The layer closest to the body has multiple sets of grooves, the layer farther away from the body is a sound insulation board, and the interlayer between the grooves and the sound insulation board is sound-absorbing cotton.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the correction component can automatically sense and trigger the correction system when the rotor oscillates radially, without the need for external control signals, realizing mechanical self-triggering, and achieving bilateral synchronous response through rack, transmission gear, pulley group and bevel gear group, ensuring consistent correction action, realizing multi-directional rolling synchronous pressure mechanism, suppressing rotor offset within a safe threshold, and significantly extending rotor life.

[0017] The lubrication component automatically delivers lubricating oil to the sponge layer and applies it to the straightening balls as they contact and straighten the rotor. This forms a continuous lubricating film, ensuring multi-point clamping force while reducing mechanical resistance. It also achieves dual functions through mechanical linkage with the straightening component. Furthermore, the rolling characteristics of the straightening balls allow the rotor to maintain low-resistance rotation during the straightening process.

[0018] By using a touch panel in conjunction with a push-button alarm, an audible and visual alarm can be automatically triggered when the rotor swings, alerting the driver and reducing the safety hazards caused by the driver continuing to drive due to rotor swing. In addition, the corrugated sleeve design can absorb a certain amount of axial displacement and vibration, and provide simple protection for the mechanisms and components on the first and second mounting plates, reducing the interference caused by external physical factors to the above components.

[0019] By employing a three-layer composite design for the noise reduction frame, utilizing grooves, sound-absorbing cotton, and sound insulation panels, a synergistic mechanism of diffraction attenuation, sound absorption, and sound insulation is achieved. This results in broadband noise suppression, attenuation of motor mechanical vibration, and reduction of resonance noise. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0034] like Figures 1-10 As shown, a low-noise drive motor includes a body 1, which is the main structure of the motor and contains electromagnetic components such as a stator, which plays a core role in energy conversion and transmission. A base 2 is installed at the bottom of the body 1 to fix the overall position of the body 1 and connect the body 1 to an external frame. Inside the body 1, there is a rotor 3 that rotates under the action of an electromagnetic field, converting electrical energy into mechanical energy to drive the load device. On the outer wall of the body 1, near the rotor 3, multiple sets of mounting legs 5 are fixedly connected to the outer wall by screws. A first mounting plate 6 is fixedly connected to the other end of the mounting legs 5. Multiple sets of telescopic rods 7 are fixedly connected to the edge of the first mounting plate 6 away from the mounting legs 5. A second mounting plate 8 is fixedly connected to the moving end of the telescopic rod 7. A correction component is set on the first mounting plate 6 and the second mounting plate 8 and is used in conjunction with the rotor 3.

[0035] like Figures 1-6As shown, the correction assembly includes a transmission box 9, which is fixedly connected to the first mounting plate 6. A transmission push plate 10 is slidably connected inside the transmission box 9. An arc-shaped plate 11 is fixedly connected to one end of the transmission push plate 10 away from the inside of the transmission box 9. The other end of the arc-shaped plate 11 away from the transmission push plate 10 is close to the outer wall of the rotor 3. A cavity 24 is opened inside the end of the transmission push plate 10 away from the arc-shaped plate 11. A rack 12 is fixedly connected inside the cavity 24. A mounting bracket 13 is fixedly connected inside the transmission box 9, and a first transmission rod 16 is rotatably connected to the other end of the mounting bracket 13. A transmission rod 16 is fixedly connected to the middle of the first transmission rod 16, which meshes with the rack 12. Gear 15, one end of the first transmission rod 16 passes through the interior of the transmission box 9, and the parts on the first mounting plate 6 and the second mounting plate 8 are identical; the straightening assembly also includes a second transmission rod 17 and a support plate 19. The second transmission rod 17 is rotatably mounted on the first mounting plate 6, and the support plate 19 is rotatably mounted on the first mounting plate 6. A first pulley group 18 is provided between one end of the second transmission rod 17 and the first transmission rod 16. A threaded cylinder 22 rotatably passes through one end of the support plate 19. A bevel gear group 14 is driven between one end of the threaded cylinder 22 and the second transmission rod 17. The threaded cylinder 22 is located away from the bevel gear group 14. The first mounting plate 6 has a threaded connection to a screw 23, and the other end of the screw 23 is connected to an arc-shaped push block 20 that is slidably connected to the first mounting plate 6. The parts on the first mounting plate 6 and the second mounting plate 8 are identical. The straightening assembly also includes a rotating ring 25 and a rotating rod 27. The rotating ring 25 is rotatably mounted on the first mounting plate 6. A connecting plate 21 is fixed to one side of the edge of the rotating ring 25. The connecting plate 21 abuts against one end of the arc-shaped push block 20. Multiple sets of square frames 26 are equidistantly mounted inside the rotating ring 25. Multiple sets of rotating rods 27 are also provided. The multiple sets of rotating rods 27 are equidistantly mounted on the edge of the first mounting plate 6, and one end of the rotating rod 27 is... A connecting frame 28 is fixedly connected inside the sliding through square frame 26. The end of the connecting frame 28 away from the rotating rod 27 is rotatably connected to a rotating shaft 29. A straightening ball 30 is fixedly connected to the middle of the rotating shaft 29. One side of the outer wall of the straightening ball 30 is close to the outer wall of the rotor 3. A lubrication assembly is provided inside the connecting frame 28. The parts on the first mounting plate 6 and the second mounting plate 8 are identical. The straightening assemblies on the first mounting plate 6 and the second mounting plate 8 are arranged in a mirror image. A torsion spring is provided between the rotating ring 25 and the first mounting plate 6 and the second mounting plate 8. The torsion spring force can make the connecting plate 21 and one end of the arc-shaped push block 20 make tight elastic contact.

[0036] During operation, rotating the threaded cylinder 22 drives the screw 23, which, guided by the connecting plate 21, converts rotational motion into linear displacement. At this time, the arc-shaped push block 20 moves closer to or further away from the connecting plate 21. Under the action of the torsion spring and the thrust of the arc-shaped push block 20, the rotating ring 25 rotates around the center of the first mounting plate 6 or the second mounting plate 8, causing the square frame 26 to rotate with the rotating ring 25. This forces the rotating rod 27 to slide and deflect within the square frame 26, thereby causing the straightening ball 30 to move closer to or further away from the outer wall of the rotor 3. This adjusts the gap between the straightening ball 30 and the outer wall of the rotor 3, keeping them close yet maintaining a non-contact state. Simultaneously, the threaded cylinder 22 drives the second transmission rod 17 to rotate via the bevel gear set 14, and transmits power to the first transmission rod 16 via the first pulley set 18. This causes the first transmission rod 16 to drive the transmission gear 15 to rotate, and engages the rack 12 to convert the rotational motion into linear motion. This causes the transmission push plate 10 to move the arc-shaped plate 11 closer to or further away from the outer wall of the rotor 3, adjusting the gap between the arc-shaped plate 11 and the outer wall of the rotor 3, keeping them close but not in contact. This completes the initial state adjustment of the straightening assembly. Furthermore, the thread helix angle and friction angle of the threaded cylinder 22 and the screw 23 are matched, and the thread pair design satisfies the condition that the thread helix angle λ < the equivalent friction angle ρv, achieving the self-locking condition of the trapezoidal thread pair.

[0037] When rotor 3 oscillates radially due to bearing damage, its outer wall periodically contacts and pushes the two sets of arc-shaped plates 11, causing the two sets of arc-shaped plates 11 to push their corresponding transmission push plates 10 to slide within the transmission box 9. At this time, the rack 12 inside the transmission push plate 10 moves with it and meshes with the transmission gear 15 to drive the first transmission rod 16 to rotate, converting linear motion into rotational motion. The first transmission rod 16 transmits power to the second transmission rod 17 through the first pulley set 18, achieving synchronous response of the first mounting plate 6 and the second mounting plate 8 on both sides. Subsequently, the second transmission rod 17 drives the bevel gear set 14 to convert horizontal rotation into vertical power, driving the screw... The threaded cylinder 22 rotates, and the threaded cylinder 22 and the screw 23 convert the rotational motion into linear displacement, pushing the arc-shaped push block 20 to move on the first mounting plate 6 and the second mounting plate 8. This pushes the connecting plate 21 on the inclined surface, forcing the rotating ring 25 to rotate around the center of the first mounting plate 6 and the second mounting plate 8. The square frame 26 inside the rotating ring 25 rotates with the rotating ring 25, forcing the rotating rod 27 to slide and deflect within the square frame 26. At this time, multiple sets of rotating rods 27 drive multiple sets of straightening balls 30 to move synchronously towards the outer wall of the rotor 3, pressing the surface of the rotor 3 to form a multi-point dynamic clamping that is evenly distributed around the circumference. The straightening balls 30 can rotate with the rotor 3, reducing frictional loss.

[0038] In summary, the correction component can automatically sense and trigger the correction system when the rotor 3 oscillates radially, without the need for external control signals, achieving mechanical self-triggering. The rack 12, transmission gear 15, first pulley group 18 and bevel gear group 14 achieve bilateral synchronous response, ensuring consistent correction action and realizing a multi-directional rolling synchronous pressure mechanism, suppressing the rotor 3 offset within a safe threshold and significantly extending the life of the rotor 3. Example

[0039] like Figure 8 As shown, the lubrication assembly includes a third transmission rod 32 and an oil tank 35. The third transmission rod 32 passes through the inner wall of the connecting frame 28 and is connected to one end of the rotating shaft 29 via a second pulley group 33. A support rod 31 is rotatably connected to the middle of the third transmission rod 32, and the other end of the support rod 31 is fixedly connected to the bottom wall of the connecting frame 28. A cam 34 is fixedly connected to the end of the third transmission rod 32 away from the second pulley group 33. The oil tank 35 is installed on the inner bottom wall of the connecting frame 28. A press pump 36 is installed at one end of the oil tank 35. An arc-shaped plate 37, opposite to the position of the cam 34, is fixedly connected to the end of the press pump 36 away from the oil tank 35. The press pump 36 outputs... The oil inlet is connected to an infusion tube 38. The lubrication assembly also includes a support housing 39, which is used to fix the sponge layer 40 and protect the internal structure. The support housing 39 is fixed to the end of the connecting frame 28 near the straightening ball 30. The sponge layer 40 is fixed to the side of the support housing 39 near the straightening ball 30. The sponge layer 40 is used to absorb lubricating oil to form a slow-release oil film that adheres to the surface of the straightening ball 30. The end of the infusion tube 38 away from the press pump 36 extends into the sponge layer 40 and is connected to a nozzle 41. The outer wall of the nozzle 41 has multiple diversion holes 42. The diversion holes 42 are used to ensure uniform distribution of oil mist. (See instruction manual) Figure 8 It can be seen that the oil tank 35 is equipped with an oil filling pipe at one end, the oil filling pipe end is equipped with a pipe cap, and one end of the oil filling pipe extends to the outside of the connecting frame 28 to support rapid oil filling.

[0040] During operation, when the straightening ball 30 contacts and straightens the rotor 3, the straightening ball 30 will rotate with the rotor 3 and drive the third transmission rod 32 to rotate through the second pulley group 33 via the rotating shaft 29. This causes the third transmission rod 32 to drive the cam 34 to periodically squeeze the arc-shaped plate 37, triggering the reciprocating motion of the press pump 36. At this time, the press pump 36 draws oil from the oil tank 35 and delivers it to the nozzle 41 through the infusion pipe 38. The nozzle 41 sprays the lubricating oil evenly onto the sponge layer 40 through the multi-component flow holes 42 to achieve slow release of lubricant. After the sponge layer 40 absorbs the lubricating oil, it rolls into contact with the straightening ball 30 to form a continuous lubricating film, further reducing the friction coefficient and friction temperature rise coefficient between the straightening ball 30 and the rotor 3.

[0041] In summary, the lubrication assembly automatically delivers lubricating oil to the sponge layer 40 and applies it to the straightening balls 30 during contact and straightening of the rotor 3, forming a continuous lubricating film. This ensures multi-point clamping force while reducing mechanical resistance. Furthermore, it achieves a dual function through mechanical linkage with the straightening assembly. The rolling characteristics of the straightening balls 30 also allow the rotor 3 to maintain low-resistance rotation during the straightening process. Example

[0042] like Figures 1-4 , Figure 9 As shown, a push-button alarm 45 is installed in the center of the arc-shaped plate 11. The push-button alarm 45 is integrated into the center of the arc-shaped plate 11 and emits a 105dB audible and visual alarm after being triggered, which complies with the ISO7731 standard. Depending on the vehicle configuration, the push-button alarm 45 can be equipped with a wireless transmission module to support remote monitoring. A touch plate 43 is slidably connected inside the arc-shaped plate 11. The touch plate 43 serves as the first sensing mechanism for the rotor 3. A return spring 44 is provided between the touch plate 43 and the four corners of the arc-shaped plate 11 to provide elastic return force. A corrugated sleeve 46 is sleeved between the first mounting plate 6 and the second mounting plate 8. One end of the corrugated sleeve 46 is fixed to the edge of the first mounting plate 6 by multiple sets of bolts 47.

[0043] During operation, when the rotor 3 contacts the arc-shaped plate 11, it will first push the contact plate 43, causing the contact plate 43 to slide under force. After compressing the return spring 44, it will contact the push-button alarm 45, triggering an audible and visual alarm to remind the driver and reduce the safety hazards caused by the driver continuing to drive due to the rotor 3 swinging. The return spring 44 ensures that the contact plate 43 automatically returns to its original position when there is no external force, and avoids false alarms caused by vehicle bumps. The flexible structure of the corrugated sleeve 46 can convert mechanical vibration energy into elastic potential energy, dissipating energy through repeated deformation, reducing vibration transmission efficiency, and providing simple protection for the mechanisms and components on the first mounting plate 6 and the second mounting plate 8, reducing interference from external physical factors to these components. It can also adaptively stretch its length according to the distance between the first mounting plate 6 and the second mounting plate 8. Example

[0044] like Figure 1 , Figure 10 As shown, multiple sets of mounting blocks 49 are also fixed to the base 2 by multiple sets of bolts 47. Multiple sets of mounting blocks 49 are together fixed to a noise reduction frame 48. The noise reduction frame 48 has three layers inside. The layer closest to the body 1 has multiple sets of grooves 50. The layer away from the body 1 is a sound insulation board 4. The interlayer between the grooves 50 and the sound insulation board 4 is a sound-absorbing cotton 51.

[0045] During operation, the noise reduction frame 48 employs a three-layer composite design. The grooves 50 disperse the sound wave reflection path, forming a sound wave diffraction layer. The honeycomb structure further disperses the mechanical vibration sound waves generated by the machine body 1, reducing the direct sound intensity. The sound-absorbing cotton 51, made of polyester fiber, forms a broadband sound-absorbing layer, absorbing mid-to-high frequency noise and reducing sound wave reflection. Simultaneously, the sound insulation board 4, a composite damping board, forms a sound barrier, blocking the outward propagation of residual low-frequency noise. This achieves broadband noise suppression through a synergistic mechanism of diffraction attenuation, sound absorption, and sound insulation. The modular installation design using bolts 47 facilitates maintenance and replacement.

[0046] The descriptions of the orientation and relative positional relationships of the structures in this invention, such as front, back, left, right, up, and down, do not constitute a limitation of this invention, but are merely for the convenience of description.
