Description

Technical Field

[0001] This application relates to the field of wind turbine vibration damping structure technology, and in particular to an integrated wind turbine vibration damping structure and its assembly process. Background Technology

[0002] Wall-mounted air conditioners typically use a cross-flow fan and an internal rotor motor connected together to rotate and deliver air. A traditional connection method, such as the cross-flow fan disclosed in patent application CN215486657U, involves a cross-flow fan rotatably mounted inside the air conditioner casing, while the internal rotor motor is fixedly mounted outside the casing. The output end of the internal rotor motor extends into the air conditioner casing and is connected to the cross-flow fan via a connector, allowing the internal rotor motor to drive the cross-flow fan to rotate and deliver air.

[0003] However, in air conditioning wall-mounted systems, the cross-flow fan and the inner rotor motor often generate vibration noise due to resonance. Therefore, the air duct connection structure of the outer rotor motor and the cross-flow fan disclosed in the patent announcement number CN221380685U adopts the outer rotor motor method. An elastic structure is set between the outer rotor motor and the air conditioner casing. The cross-flow fan is fixed to the cross-flow duct as a whole through a soft connection, which helps to reduce the vibration of the motor and thus reduce the vibration noise of the air conditioning wall-mounted unit.

[0004] This application provides another integrated fan impeller vibration damping structure to reduce the vibration and noise of wall-mounted air conditioners, thereby improving the user experience of wall-mounted air conditioners. Summary of the Invention

The movable square rod is slidably mounted in a reserved sliding slot of the outer rotor motor and is threadedly connected to the rotating shaft. The pushing wedge is integrally mounted on the end of the movable square rod away from the rotating shaft. The locking magnetic block is slidably mounted in a reserved shrinking slot of the outer rotor motor. The locking magnetic block and the pushing wedge are magnetically attracted to each other. During the process of the pushing wedge pushing the locking magnetic block to slide out of the shrinking slot, the locking magnetic block abuts against the second shock-absorbing unit.

[0012] Optionally, the synchronization mechanism includes a synchronization gear ring and multiple sets of synchronization gears. The multiple sets of synchronization gears are respectively fixedly mounted on the ends of multiple rotating circular shafts away from the corresponding moving square rods. The synchronization gear ring is fixedly mounted with an annular slider. The external rotor motor is provided with an annular groove. The annular slider is slidably mounted in the annular groove so that the synchronization gear ring always remains engaged with the multiple sets of synchronization gears.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses an integrated wind turbine vibration damping structure.

[0028] Example 1:

[0029] Reference Figure 1-3 The integrated fan impeller vibration damping structure includes an air conditioner housing, an external rotor motor 1, and a cross-flow fan 2. The cross-flow fan 2 is rotatably installed inside the air conditioner housing, and the external rotor motor 1 is fixedly installed on one side of the air conditioner housing. The external rotor motor 1 is connected to the cross-flow fan 2 for transmission, so that the external rotor motor 1 drives the cross-flow fan 2 to rotate and deliver air.

[0030] The structure and implementation principle of the air conditioner housing (not shown in the figure), the structure and implementation principle of the external rotor motor 1, the structure and implementation principle of the cross-flow fan 2, the connection method between the air conditioner housing and the cross-flow fan 2, and the connection method between the air conditioner housing and the external rotor motor 1 are all disclosed in the prior art and will not be repeated here; the focus is on describing the connection method between the cross-flow fan 2 and the external rotor motor 1.

[0031] Specifically, the outer rotor motor 1 has a rotating rotor on the outside and a stationary stator inside. A first connecting part 31 is fixedly installed on the outside of the outer rotor motor 1. The first connecting part 31 is a metal cylindrical structure. A second connecting part 32 is fixedly installed on one side of the cross-flow impeller 2. The second connecting part 32 is also a metal cylindrical structure. The second connecting part 32 is located outside the first connecting part 31 and is coaxially arranged with the first connecting part 31 (the inner diameter of the second connecting part 32 is greater than the outer diameter of the first connecting part 31). A gap of about 1 cm is formed between the inner circumference of the second connecting part 32 and the outer circumference of the first connecting part 31. The gap formed between the inner circumference of the second connecting part 32 and the outer circumference of the first connecting part 31 is integrally filled with a first damping unit 33.

[0032] The first damping unit 33 is a rubber damping layer made of damping rubber material, and the first damping unit 33 is integrally filled between the inner periphery of the second connecting part 32 and the outer periphery of the first connecting part 31 by injection molding. The above-mentioned integral filling method is disclosed in the prior art, specifically an insert injection molding process. The second connecting part 32 and the first connecting part 31, which have a higher melting point, are pre-embedded in the injection mold. Then, the damping rubber material with a lower melting point and in a molten state is injected into the injection mold. After cooling, the first damping unit 33 can be formed between the inner periphery of the second connecting part 32 and the outer periphery of the first connecting part 31, and it has good connection performance. For details, please refer to the insert injection molding process disclosed at (https: / / haokan.baidu.com / v?pd=wisenatural&vid=8947099649177415714), which will not be described in detail here.

[0033] In this embodiment, the cross-flow impeller 2 is fixedly provided with a central shaft 4. The central shaft 4 is coaxially arranged with the second connecting part 32 and the first connecting part 31. The stator of the external rotor motor 1 is provided with a central hole. The central shaft 4 is rotatably disposed in the central hole of the rotor of the external rotor motor 1. The rotation method of the central shaft 4 and the central hole is disclosed in the prior art and will not be described here.

[0034] During assembly, S1, the first shock-absorbing unit 33 is integrally set between the inner periphery of the second connecting part 32 and the outer periphery of the first connecting part 31 using insert injection molding; S2, the cross-flow fan 2 is rotated and installed on the side of the air conditioner housing away from the external rotor motor 1; S3, the external rotor motor 1 is embedded and fixedly installed on the other side of the air conditioner housing by translation. During this process, the central shaft 4 is inserted and rotated at the center of the external rotor motor 1, and the first connecting part 31 is fitted into and fixedly installed on the outer periphery of the external rotor motor 1.

[0035] During the use of the air conditioning wall-mounted unit system, the cross-flow fan 2 and the inner rotor motor often generate vibration noise due to resonance. At this time, the first damping unit 33 set between the outer rotor motor 1 and the cross-flow fan 2 helps to reduce the resonance between the cross-flow fan 2 and the outer rotor motor 1, thereby reducing vibration noise and improving the user experience of the air conditioning wall-mounted unit.

[0036] In this embodiment, the length of the first connecting part 31 is 2 / 3 of the length of the second connecting part 32, and the length of the first damping unit 33 is adapted to the length of the second connecting part 32. The first connecting part 31, the second connecting part 32 on the side away from the cross-flow fan 2, and the first damping unit 33 on the side away from the cross-flow fan 2 are flush. Specifically, the length of the first connecting part 31 is 20cm, and the lengths of the second connecting part 32 and the first damping unit 33 are 30cm. In the process of using insert injection molding to integrally set the first damping unit 33 between the inner periphery of the second connecting part 32 and the outer periphery of the first connecting part 31, the injection cavities of the first connecting part 31, the second connecting part 32, and the first damping unit 33 are controlled to be flush, so as to achieve the flush setting of the first connecting part 31, the second connecting part 32 on the side away from the cross-flow fan 2, and the first damping unit 33 on the side away from the cross-flow fan 2.

[0037] Example 2:

[0038] The difference between this embodiment and embodiment one is that an installation module 5 is also provided between the external rotor motor 1 and the first connecting part 31 in this embodiment.

[0039] Reference Figure 3-5 In this embodiment, an installation module 5 is provided between the outside of the rotor of the external rotor motor 1 and the first connecting part 31. During the process of the external rotor motor 1 being embedded and fixedly installed on the other side of the air conditioner housing in a translational manner, in addition to the central shaft 4 being inserted and rotatably set at the center of the external rotor motor 1, the first connecting part 31 is fitted into and fixedly set on the outer periphery of the rotor of the external rotor motor 1 through the installation module 5.

[0040] The mounting module 5 specifically includes multiple sets of second damping units 51, multiple sets of locking mechanisms 52, and a synchronization mechanism 53. The outer rotor motor 1 has multiple mounting grooves 54 evenly arranged around its rotor, extending along the length of the central axis 4 and open on one side and closed on the other. The multiple sets of second damping units 51 are also rubber damping strips made of damping rubber material, extending along the length of the central axis 4. The second damping units 51 are also integrally and evenly arranged around the inner circumference of the first connecting part 31 using an insert injection molding process, and the second damping units 51 and the mounting grooves 54 have an interference fit. During the fit, glue is pre-applied to the inner wall of the mounting groove 54. In step S3, when the outer rotor motor 1 is inserted and fixedly mounted on the other side of the air conditioner casing using a translational method, the deformable characteristics of the second damping units 51 allow them to be embedded into the mounting grooves 54, thus achieving an adhesive and fixed effect between the second damping units 51 and the mounting grooves 54. Multiple sets of locking mechanisms 52 are evenly arranged on the rotor of the external rotor motor 1, so that the multiple sets of locking mechanisms 52, multiple sets of second damping units 51, and multiple sets of mounting slots 54 are arranged in a corresponding manner. The multiple sets of locking mechanisms 52 lock the corresponding second damping units 51 into the corresponding mounting slots 54, thereby achieving a fixing method that combines bonding and locking to improve connection stability. The synchronization mechanism 53 is arranged on the rotor of the external rotor motor 1, and the synchronization mechanism 53 is used to drive the multiple sets of locking mechanisms 52 to lock synchronously.

[0041] In the above, multiple sets of locking mechanisms 52, multiple sets of second damping units 51, and multiple sets of mounting slots 54 are provided one-to-one. The specific number can be determined according to the actual situation. In this application, eight sets of locking mechanisms 52, second damping units 51, and mounting slots 54 are provided. All sets of locking mechanisms 52, multiple sets of second damping units 51, and multiple sets of mounting slots 54 are evenly distributed around the central axis 4.

[0042] Before applying adhesive to the inner wall of the mounting groove 54, during the process of embedding and fixing the external rotor motor 1 to the other side of the air conditioner casing in S3 using a translational method, the second damping unit 51 is embedded into the mounting groove 54, so that the second damping unit 51 and the mounting groove 54 form an adhesive and fixed effect. Subsequently, the synchronizing mechanism 53 drives multiple sets of locking mechanisms 52 to lock synchronously, so that the multiple sets of locking mechanisms 52 respectively lock the corresponding second damping unit 51 to the corresponding mounting groove 54, realizing a fixed method of adhesive + locking to improve connection stability. The second damping unit 51 also helps to reduce the resonance between the cross-flow fan 2 and the external rotor motor 1, thereby reducing vibration noise and improving the user experience of the air conditioner.

[0043] The locking mechanism 52 described above specifically includes a rotating round shaft 521, a movable square rod 522, a pushing wedge 523, and a locking magnetic block 524. The rotating round shaft 521 is a metal round rod structure. The rotor of the external rotor motor 1 has a pre-reserved rotating groove 525 adapted to the rotating round shaft 521. The rotating round shaft 521 is rotatably mounted in the rotating groove 525 via a miniature bearing. The movable square rod 522 is a metal square rod structure. The rotor of the external rotor motor 1 has a pre-reserved sliding groove 526 adapted to the movable square rod 522. The movable square rod 522 is slidably mounted in the pre-reserved sliding groove 526 on the rotor of the external rotor motor 1, and is threadedly connected to the rotating round shaft 521. The pushing wedge 523 is a right-angled trapezoidal structure. The pushing wedge 523 is integrally mounted on the end of the movable square rod 522 away from the rotating round shaft 521, and pushes... The side of the advancing wedge 523 away from the central axis 4 is a wedge-shaped surface. It is worth mentioning that the sliding groove 526 is provided with a clearance position in the area corresponding to the advancing wedge 523 to meet the condition that the advancing wedge 523 slides with the moving square rod 522. The locking magnet 524 is a permanent magnet. The rotor of the outer rotor motor 1 has a shrinkage groove 527 that matches the locking magnet 524 in the area corresponding to the clearance position. The side of the locking magnet 524 near the central axis 4 is also a wedge-shaped surface, and the wedge-shaped surface of the advancing wedge 523 matches the wedge-shaped surface of the locking magnet 524. The side of the locking magnet 524 away from the central axis 4 is a triangular structure, which is mainly used to forcibly squeeze the second damping unit 51 during the process of the advancing wedge 523 pushing the locking magnet 524 to slide out of the shrinkage groove 527, that is, the locking magnet 524 and the second damping unit 51 are pressed together.

[0044] The aforementioned synchronization mechanism 53 specifically includes a synchronization gear ring 531 and multiple sets of synchronization gears 532. The number of synchronization gears 532 is eight, matching the number of rotating shafts 521. The end of the rotating shaft 521 away from the moving square rod 522 extends outwards from the rotor of the external rotor motor 1. Multiple sets of synchronization gears 532 are respectively fixedly mounted on the ends of the multiple sets of rotating shafts 521 away from their corresponding moving square rods 522. An annular slider 533 is integrally fixedly mounted on one side of the synchronization gear ring 531. An annular groove 534 is provided on the side of the rotor of the external rotor motor 1 away from the cross-flow fan 2. Both the annular groove 534 and the annular slider 533 are T-shaped. The cross-section allows the annular slider 533 to slide in the annular groove 534, and ensures that the synchronous gear ring 531 is always engaged with multiple sets of synchronous gears 532. Each of the multiple sets of rotating shafts 521 has a drive groove 535 at the end furthest from the corresponding moving square rod 522. The drive groove 535 has a cross-shaped groove, a slotted groove, a hexagonal groove, etc., mainly to facilitate the rotation of the rotating shaft 521 using tools such as screwdrivers and hexagonal keys. It is worth mentioning that the rotor of the external rotor motor 1 also has a through hole corresponding to one of the drive grooves 535, allowing tools such as screwdrivers and hexagonal keys to pass through the through hole and be inserted into the drive groove 535.

[0045] After the second damping unit 51 is embedded in the mounting groove 54, an external tool is inserted into one of the drive grooves 535 to drive the corresponding rotating shaft 521 to rotate. Multiple sets of synchronous gears 532 rotate synchronously under the linkage of synchronous gear ring 531 and drive multiple sets of rotating shafts 521 to rotate synchronously. Multiple sets of rotating shafts 521 drive the corresponding moving square rod 522 and the push wedge 523 to slide through the threaded connection, so that multiple sets of push wedges 523 push multiple sets of locking magnetic blocks 524 to slide out of the shrinkage groove 527, so that multiple sets of locking magnetic blocks 524 forcibly squeeze the corresponding second damping unit 51 to achieve locking.

[0046] Implementation Principle: During assembly, S1, the first damping unit 33 is integrally installed between the inner circumference of the second connecting part 32 and the outer circumference of the first connecting part 31 using insert injection molding; S2, the side of the cross-flow fan 2 away from the external rotor motor 1 is rotated and installed on one side of the air conditioner casing; S3, the external rotor motor 1 is embedded and fixedly installed on the other side of the air conditioner casing using a translation method. During this process, the central shaft 4 is inserted and rotated at the center of the external rotor motor 1, and the first connecting part 31 is fitted and fixedly installed on the outer circumference of the external rotor motor 1. During the use of the air conditioner wall-mounted system, the cross-flow fan 2 and the internal rotor motor often generate vibration noise due to resonance. At this time, the first damping unit 33 installed between the external rotor motor 1 and the cross-flow fan 2 helps to reduce the resonance between the cross-flow fan 2 and the external rotor motor 1, thereby reducing vibration noise and improving the user experience of the air conditioner wall-mounted unit.
