Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a vibration damping device, a compressor structure, and an air conditioner. Background Technology

[0002] In the traditional commercial air conditioning industry, the compressor, as the core driving component of the system, generates significant vibration and noise during operation. This vibration not only puts stress on the internal structure of the air conditioning equipment, affecting its stability and lifespan, but also transmits noise pollution to the external environment through the contact points between the equipment and the ground or supporting structure. Vibration can also trigger resonance in other internal components, further exacerbating the noise problem. Summary of the Invention

[0003] The main objective of this invention is to provide a vibration damping device, a compressor structure, and an air conditioner to solve the problem of vibration and noise generated by compressors during operation in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a vibration damping device is provided, comprising a vibration damping structure, the vibration damping structure including a vibration damping housing and a limiting member, at least a portion of the limiting member being movably disposed within the vibration damping housing along a predetermined direction;

[0005] An elastic limiting structure is installed on the vibration damping housing. The elastic limiting structure has a first elastic connecting end and a second elastic connecting end spaced apart along a preset direction. Both the first elastic connecting end and the second elastic connecting end are connected to the limiting component. The elastic limiting structure has an elastic deformation state so as to limit the movement stroke of the limiting component during the movement of the limiting component.

[0006] Furthermore, the vibration damping structure also includes a vibration damping hole provided on the vibration damping housing, and the limiting component includes a first limiting part and a second limiting part. The second limiting part is disposed in the vibration damping hole, and at least a portion of the first limiting part is located in the vibration damping hole. The first elastic connecting end and the second elastic connecting end of the elastic limiting structure are both connected to the second limiting part.

[0007] Furthermore, the vibration damping housing has vibration damping holes, and a movable gap is formed between the limiting component and the vibration damping holes. The vibration damping device also includes an air guiding component installed on the vibration damping housing. One end of the air guiding component is connected to the movable gap so as to exhaust the gas generated by the limiting component during the movement.

[0008] Furthermore, the vibration damping device also includes a load-bearing structure, which includes a load-bearing chassis for supporting the foundation components. At least a portion of the load-bearing chassis is provided with air ducts. The air duct component includes an air duct pipe, the first end of which is connected to the movable gap, and the second end of which is connected to the air duct. The portion of the air duct pipe between the first and second ends is laid on the load-bearing chassis to heat the load-bearing chassis with gas generated by the limiting component.

[0009] Furthermore, the gas guiding component also includes a flow obstruction component, which is disposed in the first end. One end of the flow obstruction component is at least partially connected to the limiting component. Along the flow direction of the gas generated by the limiting component during its movement, the conduction gap formed between the outer peripheral surface of the flow obstruction component and the inner wall surface of the gas guiding pipe gradually increases, so as to reduce the amount of external gas entering the moving gap from the gas guiding component.

[0010] Furthermore, the limiting component includes a first limiting part and a second limiting part. A first movable gap is formed between the outer wall surface of the first limiting part and the hole wall of the vibration damping hole. The outer wall surface of the second limiting part contacts the hole wall of the vibration damping hole. A second movable gap is formed between the end of the second limiting part away from the first limiting part and the end of the vibration damping hole. One end of the flow blocking component is connected to the second limiting part, and the other end of the flow blocking component is connected to the first end.

[0011] Furthermore, the vibration damping device also includes a load-bearing structure, which includes a load-bearing chassis. At least a portion of the load-bearing chassis is provided with a first buffer component, and a second buffer component is provided on the first buffer component. The second buffer component has a buffer surface for bearing the target component, wherein the first buffer component and the second buffer component are connected by a buffer connector.

[0012] Furthermore, the first buffer component is provided with at least one first connection position, and the second buffer component is provided with at least one second connection position. The at least one first connection position and the at least one second connection position are provided in a one-to-one correspondence. The buffer connector includes a connecting component that can be inserted into the at least one first connection position to connect the first buffer component and the second buffer component through the connecting component.

[0013] Furthermore, the buffer connector also includes a buffer member disposed on the portion of the connector located between the first buffer member and the second buffer member, in order to absorb vibrations and noise generated by the target component during movement.

[0014] Furthermore, the vibration damping device also includes a connecting structure for connecting the target component and the vibration damping housing. The connecting structure includes a first connecting part and a second connecting part. The first connecting part has a connecting surface that is adapted to the outer surface of the target component. The second connecting part is disposed on the limiting component.

[0015] Furthermore, the first connecting part includes a connecting plate, a first reinforcing part and a second reinforcing part, the connecting plate has a connecting surface, and the first reinforcing part and the second reinforcing part are respectively disposed on both sides of the connecting plate.

[0016] Furthermore, the vibration damping device also includes a sealing structure, which includes a cover plate assembly disposed on the vibration damping housing. The sealing structure also includes a sealing component disposed within the cover plate assembly. The portion of the limiting component outside the vibration damping housing passes through the sealing opening and connects to the connection structure between the cover plate assembly and the vibration damping device.

[0017] Furthermore, the cover plate assembly includes a support component and a cover plate body. The cover plate body is provided with a through hole, and the sealing component is provided with a sealing hole. The through hole and the sealing hole are provided correspondingly.

[0018] Furthermore, a vibration damping interlayer is provided inside the vibration damping housing; and / or, there are multiple vibration damping structures distributed around the periphery of the target component.

[0019] According to another aspect of the present invention, a compressor structure is provided, the compressor structure including a compressor body and a vibration damping device disposed on the compressor body, the vibration damping device being the aforementioned vibration damping device.

[0020] According to another aspect of the present invention, an air conditioner is also provided, the air conditioner including a compressor structure, the compressor structure being the compressor structure described above.

[0021] When the compressor vibrates and the limiting component moves in a preset direction, the elastic limiting structure deforms accordingly, absorbing vibration energy through the elastic properties of the internal material and converting it into elastic potential energy.

[0022] The two ends of the elastic limiting structure are connected to the limiting component and the vibration damping housing, respectively, forming a closed system for energy conversion. Under the vibration of the compressor, the movement of the limiting component causes the elastic limiting structure to deform. During the deformation process, the vibration energy is absorbed and stored by the elastic material, reducing the direct transmission of vibration energy between the compressor and the vibration damping housing, thereby reducing the vibration amplitude of the entire system.

[0023] During the vibration of the limiting component, its maximum displacement is limited by the elastic deformation characteristics of the elastic limiting structure. When the displacement of the limiting component exceeds the preset value, the elastic restoring force of the elastic limiting structure will increase significantly, thereby effectively preventing the limiting component from continuing to move and avoiding internal structural collisions or damage caused by excessive displacement. This precise control not only reduces the impact of vibration on the compressor itself, but also effectively avoids resonance caused by compressor vibration in connected pipes or components, reducing internal stress and potential damage to the equipment.

[0024] Vibration during compressor operation, especially when the vibration frequency is close to the natural frequency of the piping or supporting structure, can easily trigger resonance and generate high-intensity noise. The introduction of an elastic limiting structure reduces the likelihood of resonance by absorbing vibration energy and limiting the vibration amplitude, keeping the compressor's vibration frequency within a safe range relative to the natural frequency of the internal structure, thus avoiding resonance noise. Simultaneously, the internal friction of the elastic material during deformation further dissipates vibration energy and reduces noise propagation. Attached Figure Description

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] In the traditional commercial air conditioning industry, the compressor, as the core driving component of the system, generates significant vibration and noise during operation. This vibration not only puts stress on the internal structure of the air conditioning equipment, affecting its stability and lifespan, but also transmits it to the external environment through the contact points between the equipment and the ground or supporting structure, generating noise pollution. Vibration can also trigger resonance in other internal components, further exacerbating the noise problem.

[0038] The main objective of this application is to provide a vibration damping device, a compressor structure, and an air conditioner to solve the problem of vibration and noise generated by compressors in the prior art during operation.

[0039] Example 1

[0040] like Figures 1 to 3 As shown, this application first provides a vibration damping device, including a vibration damping structure 3. The vibration damping structure 3 includes a vibration damping housing 32 and a limiting member 31. At least a portion of the limiting member 31 is movably disposed within the vibration damping housing 32 along a preset direction.

[0041] An elastic limiting structure 33 is disposed on the vibration damping housing 32. The elastic limiting structure 33 has a first elastic connecting end and a second elastic connecting end spaced apart along a preset direction. Both the first elastic connecting end and the second elastic connecting end are connected to the limiting component 31. The elastic limiting structure 33 has an elastic deformation state so that the movement stroke of the limiting component 31 is limited by the elastic limiting structure 33 during the movement of the limiting component 31.

[0042] Specifically, in this embodiment, the elastic limiting structure 33 is a spring, and there are at least two of them. One end of all the elastic limiting structures 33 is fixed to the vibration damping housing 32, and the other end is fixed to at least a portion of the limiting component 31.

[0043] The vibration damping device in this technical solution can achieve the following: when the compressor vibrates and the limiting component 31 moves in a preset direction, the elastic limiting structure 33 deforms accordingly, absorbing vibration energy through the elastic properties of the internal material and converting it into elastic potential energy.

[0044] The two ends of the elastic limiting structure 33 are connected to the limiting component 31 and the vibration damping housing 32, respectively, forming a closed system for energy conversion. Under the action of compressor vibration, the movement of the limiting component 31 causes the elastic limiting structure 33 to deform. During the deformation process, the vibration energy is absorbed and stored by the elastic material, reducing the transmission of vibration energy directly between the compressor and the vibration damping housing 32, thereby reducing the vibration amplitude of the entire system.

[0045] During the vibration of the limiting component 31, its maximum displacement is limited by the elastic deformation characteristics of the elastic limiting structure 33. When the displacement of the limiting component 31 exceeds a preset value, the elastic restoring force of the elastic limiting structure 33 will increase significantly, thereby effectively preventing the limiting component 31 from continuing to move and avoiding internal structural collisions or damage caused by excessive displacement. This precise control not only reduces the impact of vibration on the compressor itself, but also effectively avoids resonance of connected pipes or components caused by compressor vibration, reducing internal stress and potential damage to the equipment.

[0046] Vibration during compressor operation, especially when the vibration frequency is close to the natural frequency of the pipes or supporting structure, can easily trigger resonance and generate high-intensity noise. The introduction of the elastic limiting structure 33 reduces the possibility of resonance by absorbing vibration energy and limiting the vibration amplitude, keeping the compressor's vibration frequency within a safe range from the natural frequency of the internal structure and avoiding resonance noise. At the same time, the internal friction of the elastic material during deformation further dissipates vibration energy and reduces noise propagation.

[0047] Furthermore, the vibration damping structure also includes a vibration damping hole 35 provided on the vibration damping housing 32, and the limiting component 31 includes a first limiting part 311 and a second limiting part 312. The second limiting part 312 is disposed in the vibration damping hole 35, and at least a portion of the first limiting part 311 is located in the vibration damping hole 35. The first elastic connecting end and the second elastic connecting end of the elastic limiting structure 33 are both connected to the second limiting part 312.

[0048] The elastic limiting structure 33 has two elastic ends in a preset direction, which are connected to the limiting component 31. When the compressor vibrates due to operation, causing the limiting component 31 to move in the vibration damping housing 32 in a preset direction, the elastic limiting structure 33 will deform, thereby absorbing and converting vibration energy.

[0049] During compressor vibration, as the limiting component 31 displaces, the elastic limiting structure 33 begins to deform, resulting in an elastic force that acts as additional resistance during the movement of the limiting component 31. As the displacement of the limiting component 31 increases, the deformation of the elastic limiting structure 33 increases, and the resistance provided also increases. This means that more vibrational energy is converted into elastic potential energy and stored in the elastic limiting structure 33, rather than being transferred to the entire air conditioning system or the ground. Therefore, effective buffering of compressor vibration can be achieved.

[0050] The elastic limiting structure 33 acts as a "spring" during compressor vibration, limiting the maximum displacement of the limiting component 31, thereby indirectly controlling the vibration amplitude of the compressor.

[0051] The two ends of the elastic limiting structure 33 are connected to the limiting component 31, and can be regarded as an energy buffer. During the vibration of the compressor, the displacement of the limiting component 31 is limited by the maximum deformation of the elastic limiting structure 33. Once the displacement of the limiting component 31 reaches the level that causes the elastic limiting structure 33 to reach the maximum allowable deformation, the elastic limiting structure 33 will no longer allow it to move further, thus physically limiting the vibration range.

[0052] Noise is typically caused by vibration, which in turn is caused by unbalanced forces during compressor operation. The elastic limiting structure 33 not only absorbs vibration energy and reduces the vibration itself, but also smooths the vibration curve and reduces high-frequency components through its continuous deformation and recovery during vibration. Since high-frequency vibration is a major cause of sharp noise, the application of the elastic limiting structure 33 significantly reduces the noise level of the equipment during operation, minimizing noise pollution to the surrounding environment when commercial air conditioners are used in public places, and improving the user experience.

[0053] Compressor vibration can easily cause resonance in connected internal pipes and structural components, and even lead to mechanical fatigue and damage. The application of the elastic limiting structure 33 reduces the probability of such resonance by limiting the vibration amplitude and frequency, thereby reducing pipe stress and structural component wear, and improving the overall stability of the system and the service life of the compressor.

[0054] Furthermore, the vibration damping housing 32 is provided with vibration damping holes 35, and a movable gap is formed between the limiting component 31 and the vibration damping holes 35. The vibration damping device also includes an air guiding component 6 provided on the vibration damping housing 32. One end of the air guiding component 6 is connected to the movable gap so as to guide the gas generated by the limiting component 31 during the movement through the air guiding component 6.

[0055] As the limiting component 31 vibrates, its rapid displacement within the movable gap causes the surrounding air to be compressed. This air compression process is accompanied by the release of energy, i.e., vibration energy is converted into heat energy. If this heat energy is not properly handled, it may cause the internal temperature of the damping housing 32 to rise, affecting the damping effect. However, by adding an air guide component 6 to the damping housing 32, allowing the movable gap to connect with the external environment through the air guide component 6, the heat energy converted from vibration can be discharged from the damping housing 32 through gas flow, realizing the recovery and utilization of heat energy and improving the energy utilization efficiency of the system.

[0056] If the accumulated heat inside the damping hole 35 is not discharged in time, the increased pressure may restrict the movement of the limiting component 31, affecting its response speed and damping effect. The introduction of the air guide component 6, through communication with the movable gap, timely balances the pressure difference between the inside and outside of the damping hole 35, ensuring the smooth movement of the limiting component 31 during vibration, thereby improving the efficiency and accuracy of damping and reducing the impact of vibration on the surrounding structure.

[0057] The air guide component 6 can not only exhaust hot air, but also direct this heat energy to the parts of the air conditioning system that need to be heated, such as the supporting chassis 11. This avoids frost formation caused by low temperature and high humidity environment, optimizes thermal management, reduces reliance on traditional heating methods such as electric heating belts, and reduces energy consumption.

[0058] Furthermore, the vibration damping device also includes a load-bearing structure 1, which includes a load-bearing chassis 11 for supporting the foundation components. At least a portion of the load-bearing chassis 11 is provided with air guide holes 12. The air guide component 6 includes an air guide pipe 61, the first end of which is connected to the movable gap, and the second end of which is connected to the air guide hole 12. The portion of the air guide pipe 61 between the first and second ends is laid on the load-bearing chassis 11 to heat the load-bearing chassis 11 with gas generated by the limiting component 31.

[0059] During vibration reduction, the movement of the limiting component 31 causes the gas inside the vibration damping hole 35 to be compressed, which generates heat energy. The heat energy is guided from the movable gap to the air guide hole 12 provided on the supporting chassis 11 through the air guide pipe 61, realizing the recovery and utilization of heat energy.

[0060] Because the air conditioner is prone to frost formation on the chassis 11 when operating in a low-temperature and high-humidity environment, which affects the performance of the equipment, this application uses the air duct 61 to directly heat the chassis 11 through the heat generated during vibration, thus avoiding frost formation. Compared with the traditional electric heating method, this direct reuse of heat energy avoids secondary energy conversion and loss, improves energy utilization efficiency, and achieves the goal of energy saving.

[0061] The air duct 61 is laid on the supporting chassis 11, which not only enables rapid heat transfer, but also heats the supporting chassis 11 evenly through the distribution of hot air flow, thereby improving the thermal management of the air conditioner in harsh environments.

[0062] Uniform heating prevents localized overcooling of the chassis 11, reduces temperature gradients, and improves the thermal stability of the equipment, thereby enhancing the adaptability and operational efficiency of the air conditioner under low temperature and high humidity conditions. Furthermore, by optimizing the guidance and distribution of hot airflow, the area of ​​frost formation on the chassis 11 can be reduced, ensuring the normal operation of internal components and lowering the failure rate and maintenance requirements caused by frost.

[0063] Furthermore, the air guiding component 6 also includes a flow blocking component 62, which is disposed in the first end. One end of the flow blocking component 62 is at least partially connected to the limiting component 31. Along the flow direction of the gas generated during the movement of the limiting component 31, the conduction gap formed between the outer peripheral surface of the flow blocking component 62 and the inner wall surface of the air guiding pipe 61 gradually increases, so as to reduce the amount of external gas entering the moving gap from the air guiding component 6.

[0064] The flow-blocking component 62 is connected to the limiting component 31, and its special shape design causes the guiding gap to gradually increase along the gas flow direction. This means that during the movement of the limiting component 31, the compressed gas flows through this gradually widening gap into the gas guide pipe 61, and this design reduces the possibility of external gas flowing back in.

[0065] When the compressor vibrates, the displacement of the limiting component 31 causes the gas inside the damping hole 35 to be compressed, generating heat. Without the flow-blocking component 62, external cold air may flow back into the damping hole through the gap in the air guide pipe 61, affecting the efficiency of heat recovery. The design of the flow-blocking component 62, through the gradually widening conduction gap, effectively reduces this backflow, ensuring that the hot air generated during the vibration damping process can smoothly reach the supporting chassis 11 through the air guide pipe 61, thus improving the efficiency of heat recovery and utilization.

[0066] In low-temperature and high-humidity environments, the supporting chassis 11 of the air conditioning equipment is prone to frosting, affecting equipment performance. The presence of the flow-restricting component 62 reduces the impact of external cold air on the heating zone of the supporting chassis 11, helps maintain a stable heating effect, improves the efficiency of anti-frost formation, and ensures stable operation of the equipment in harsh environments.

[0067] During vibration damping, the compression and expansion of the gas inside the damping hole 35 will cause pressure changes. If the pressure is unstable, it may affect the normal operation of the limiting component 31, thereby affecting the vibration damping effect and stability of the equipment. The flow obstruction component 62 helps to maintain the relative stability of the internal pressure of the damping housing 32 by reducing gas backflow, ensuring the normal movement of the limiting component 31 and enhancing the safety and stability of the equipment operation.

[0068] Furthermore, the limiting component 31 includes a first limiting part 311 and a second limiting part 312. A first movable gap is formed between the outer wall surface of the first limiting part 311 and the hole wall of the vibration damping hole 35. The outer wall surface of the second limiting part 312 contacts the hole wall of the vibration damping hole 35. A second movable gap is formed between the end of the second limiting part 312 away from the first limiting part 311 and the end of the vibration damping hole 35. One end of the flow blocking component 62 is connected to the second limiting part 312, and the other end of the flow blocking component 62 is connected to the first end.

[0069] The first movable gap formed between the first limiting part 311 and the wall of the vibration damping hole 35, and the contact design between the second limiting part 312 and the hole wall, provide more precise vibration control. The second movable gap between the end of the second limiting part 312 and the other end of the vibration damping hole 35 provides space for the connection of the flow-blocking component 62, ensuring its normal operation.

[0070] The coordinated operation of the first limiting part 311 and the second limiting part 312 precisely controls the displacement range of the limiting part 31 when the compressor vibrates, avoiding equipment damage caused by excessive vibration amplitude. At the same time, the connection between the flow-blocking part 62 and the second limiting part 312 ensures that vibration energy is converted into heat energy to the maximum extent, and is guided to the air guide pipe 61 through the gradually widening conduction gap, realizing efficient conversion of vibration energy and precise conduction of heat energy.

[0071] The special design of the flow-blocking component 62, in conjunction with the first limiting part 311 and the second limiting part 312, ensures the smooth flow of hot air within the air guide pipe 61, further improving the efficiency of heat energy utilization. Simultaneously, by rationally arranging the first and second movable gaps, the distribution of hot air can be controlled, achieving uniform heating of the supporting chassis 11.

[0072] During compressor vibration, the movement of the first limiting part 311 and the second limiting part 312 causes the gas inside the damping hole 35 to be compressed, generating heat energy. Under the action of the flow-blocking component 62, the flow direction and speed of the hot airflow are controlled, reducing turbulence in the air guide pipe 61, thereby improving the efficiency of heat transfer and the uniformity of heating the supporting chassis 11. This uniform heating reduces stress concentration caused by local temperature differences, improving the stability and service life of the equipment.

[0073] In low-temperature and high-humidity environments, air conditioning equipment is prone to frosting, affecting its operating efficiency. Through the design of the first limiting part 311 and the second limiting part 312, and the guidance of hot airflow by the flow-blocking component 62, this application achieves effective heating of the supporting chassis 11, preventing frosting. Compared with traditional single heating methods such as electric heating belts, this synergistic heating mechanism not only improves heating efficiency but also reduces energy consumption and optimizes the thermal management performance of the equipment.

[0074] Furthermore, the vibration damping device also includes a load-bearing structure 1, which includes a load-bearing chassis 11. At least a portion of the load-bearing chassis 11 is provided with a first buffer component 13, and a second buffer component 14 is provided on the first buffer component 13. The second buffer component 14 has a buffer surface for bearing the target component 2, wherein the first buffer component 13 and the second buffer component 14 are connected by a buffer connector 15.

[0075] The first buffer component 13 is connected to the supporting chassis 11 and plays a preliminary role in vibration absorption, while the second buffer component 14 is located above the first buffer component 13 and has a buffer surface for supporting the target component 2. The two components are connected by a buffer connector 15, forming a multi-level buffer system.

[0076] In the air conditioning system, the target component 2, such as the compressor, generates vibrations during operation. These vibrations are first absorbed and dispersed by the first buffer component 13, reducing the vibration intensity directly transmitted to the supporting chassis 11. Subsequently, the remaining vibration energy is further absorbed by the second buffer component 14. This multi-level buffer design, compared to a single buffer layer, can manage vibrations more comprehensively and meticulously.

[0077] The synergistic effect of the first buffer component 13 and the second buffer component 14 not only reduces vibration transmission, but also effectively mitigates the instantaneous impact on the target component 2 during operation through the dynamic adjustment of the buffer connector 15, thereby increasing the operational stability of the equipment.

[0078] Under different operating conditions of the air conditioner, the target component 2 may experience instantaneous impacts of varying degrees, especially during startup and shutdown. The multi-stage buffering system can adjust its buffering effect in real time according to the magnitude of the impact. Through the elastic deformation of the buffer connector 15, these instantaneous impacts are buffered, reducing the potential risk of damage to the overall structure of the equipment and improving the safety of the air conditioner in various operating modes.

[0079] In the heat recovery mechanism of this application, the supporting chassis 11 achieves the goal of preventing frost formation by receiving the heat energy generated during the movement of the limiting component 31. The introduction of the second buffer component 14, with its close contact with the target component 2, allows some of the heat energy generated by the target component 2 during operation to be conducted to the supporting chassis 11 through contact, improving heat energy utilization and reducing additional energy consumption. Simultaneously, the uniform heat distribution helps maintain the temperature stability of the supporting chassis 11, optimizing the thermal management performance of the entire system.

[0080] Furthermore, the first buffer component 13 is provided with at least one first connection position, and the second buffer component 14 is provided with at least one second connection position. The at least one first connection position and the at least one second connection position are provided in a one-to-one correspondence. The buffer connector 15 includes a connecting component 151 that can be inserted into the at least one first connection position to connect the first buffer component 13 and the second buffer component 14 through the connecting component 151.

[0081] The one-to-one correspondence between the first and second connection positions ensures the accuracy and stability of the connection between the first buffer component 13 and the second buffer component 14, while the interlocking arrangement of the connection component 151 further enhances the reliability of the connection.

[0082] When the air conditioning equipment is running, the vibration generated by the target component 2 needs to be effectively transmitted to the buffer system for energy conversion and consumption. Through the precise matching of the first connection position and the second connection position, and the solid connection of the connecting component 151, the efficient transmission of vibration energy between the two buffer components is ensured, reducing the reflection and leakage of vibration energy and enhancing the overall vibration reduction effect.

[0083] The introduction of the connecting component 151 provides an additional path for heat conduction. In particular, when the second buffer component 14 is in close contact with the target component 2, the connecting component 151 can act as a bridge for heat conduction, optimizing the distribution of heat energy.

[0084] During the long-term operation of air conditioning equipment, various buffer components may require periodic inspection and replacement to ensure their performance. The corresponding design of the first and second connection positions, as well as the interlocking connection component 151, allows maintenance personnel to easily disassemble and assemble the buffer system, reducing the complexity and time consumption of maintenance operations and improving maintenance convenience. At the same time, this design allows the buffer system to be adjusted according to equipment operating conditions, enhancing the system's adaptability and flexibility, enabling the air conditioning equipment to better meet the needs of different operating environments.

[0085] The optimized connection design between the first buffer component 13 and the second buffer component 14 reduces unnecessary loss of vibration energy and improves energy conversion efficiency. Simultaneously, the efficient heat conduction path reduces additional heating requirements and lowers energy consumption. The connecting component 151 can be a connecting bolt or a pin, and correspondingly, the first and second connecting positions are bolt holes or pin holes.

[0086] Furthermore, the buffer connector 15 also includes a buffer 152, which is disposed on the portion of the connecting member 151 located between the first buffer member 13 and the second buffer member 14, to absorb vibrations and noise generated by the target member 2 during movement.

[0087] The buffer 152 is disposed on the part of the connecting part 151 between the first buffer part 13 and the second buffer part 14. It absorbs and converts the vibration energy generated by the target part 2 during the movement by utilizing the elastic properties of its material. At the same time, its acoustic properties can effectively reduce the propagation of noise.

[0088] Air conditioning systems, such as those using compressors, generate vibrations and noise during operation. These vibrations and noises not only affect the stability and lifespan of the equipment but can also lead to a poor user experience. By adding a buffer 152 at a critical location on the connecting component 151, vibration energy can be precisely absorbed and converted into heat or other forms of energy, significantly reducing the impact of the target component on the buffer system. Simultaneously, the acoustic characteristics of the buffer 152, such as its damping effect, effectively slow down the propagation speed of sound waves and reduce their amplitude, achieving effective noise reduction.

[0089] During the operation of the air conditioning equipment, the vibration of the target component 2 may cause instability in the internal structure of the buffer system, such as loose connections or component wear. The buffer component 152 reduces the impact of vibration on the connecting component 151 and other components of the buffer system by directly absorbing vibration energy, thereby reducing the stress inside the system, enhancing the overall stability and reliability of the buffer system, reducing the equipment failure rate and maintenance costs caused by vibration, and extending the service life of the commercial air conditioning equipment.

[0090] During the operation of the air conditioner, the vibration energy absorbed by the buffer 152 is converted into heat energy. This heat energy can be effectively utilized by the system, reducing the need for additional heating. In particular, it plays a positive role in preventing frost formation on the load-bearing chassis 11 in low-temperature and high-humidity environments. Moreover, due to the efficient energy conversion of the buffer 152, the energy consumption of the air conditioning equipment during operation is reduced, improving energy utilization efficiency.

[0091] Furthermore, the vibration damping device also includes a connecting structure 4, which is used to connect the target component 2 and the vibration damping housing 32. The connecting structure 4 includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 has a connecting surface 411, which is adapted to the outer surface of the target component 2. The second connecting part 42 is disposed on the limiting component 31.

[0092] The fitting design of the first connecting part 41 with the outer surface of the target component 2 ensures the tightness and firmness of the connection, reducing the gaps that may exist between the target component 2 and the connecting structure 4 during operation, thereby effectively reducing the leakage of vibration energy. The second connecting part 42 is directly connected to the limiting component 31, so that the vibration of the target component 2 can be quickly and effectively transmitted to the vibration damping housing 32, and converted and dissipated through the internal pneumatic vibration damping mechanism.

[0093] When air conditioning equipment is running, if the vibration energy generated by the compressor and other components is not fully absorbed, it will diffuse into the entire system through the connection points, exacerbating noise and equipment wear. The precise fit design of the first connection part 41 reduces energy loss during the conversion of vibration energy between the outer casing and the target component 2, improving the energy conversion rate and thus enhancing the vibration reduction effect. Simultaneously, the direct connection between the second connection part 42 and the limiting component 31 ensures the immediate transmission and processing of vibration energy, further strengthening the vibration reduction effect and reducing potential damage to the equipment structure caused by vibration.

[0094] The first connecting part 41 and the second connecting part 42 of the connecting structure 4 work together to not only ensure the stable positioning of the target component 2 on the vibration damping housing 32, but also enhance the positioning accuracy and reduce the additional vibration caused by position offset through the special design of the connecting surface 411.

[0095] Furthermore, the first connecting portion 41 includes a connecting plate 412, a first reinforcing portion 413 and a second reinforcing portion 414. The connecting plate 412 has a connecting surface 411, and the first reinforcing portion 413 and the second reinforcing portion 414 are respectively disposed on both sides of the connecting plate 412.

[0096] By providing a first reinforcing part 413 and a second reinforcing part 414 on both sides of the connecting plate 412, the rigidity of the connecting structure 4 is increased, which not only improves the load-bearing capacity of the connecting structure 4, but also reduces the vibration transmission caused by the deformation of the connecting structure 4, thereby enhancing the fatigue resistance and vibration reduction effect of the connecting structure 4.

[0097] Furthermore, the vibration damping device also includes a sealing structure 5, which includes a cover plate assembly 51. The cover plate assembly 51 is disposed on the vibration damping housing 32. The sealing structure 5 also includes a sealing component 52 disposed within the cover plate assembly 51. The portion of the limiting component 31 outside the vibration damping housing 32 passes through the sealing opening and connects to the connection structure 4 between the cover plate assembly 51 and the vibration damping device.

[0098] The cover plate assembly and sealing components ensure the airtightness of the vibration damping housing 32 to the external environment, prevent the intrusion of external impurities and internal gas leakage, maintain the stability of the air pressure inside the vibration damping housing 32, and enhance the airtightness and long-term operational reliability of the vibration damping structure 3.

[0099] Furthermore, the cover plate assembly 51 includes a support member 511 and a cover plate body 512. The cover plate body 512 is provided with a through hole, and the sealing member 52 is provided with a sealing hole. The through hole and the sealing hole are provided correspondingly.

[0100] The combination of the support component 511 and the cover plate body 512 provides a solid support for the sealing structure 5, ensuring the alignment and sealing between the sealing port at the top of the vibration damping housing 32 and the connecting structure 4, reducing the decline in vibration damping performance caused by assembly errors, and improving the overall sealing performance and stability of the system.

[0101] Furthermore, a vibration damping interlayer 34 is provided inside the vibration damping housing 32; and / or, there are multiple vibration damping structures 3, which are distributed around the target component 2.

[0102] The damping layer 34 installed inside the damping housing 32 increases the damping effect of the damping structure 3, improves the energy loss of the compressor during vibration, and reduces vibration amplitude and noise. Furthermore, the distribution of multiple damping structures 3 allows for comprehensive control of the compressor's vibration from multiple directions, avoiding the limitations of single-point damping, improving the overall effectiveness of the damping system, and enhancing the equipment's adaptability and stability in complex environments.

[0103] Example 2

[0104] This application embodiment also provides a compressor structure, which includes a compressor body and a vibration damping device disposed on the compressor body, the vibration damping device being the aforementioned vibration damping device.

[0105] The aforementioned vibration damping device is applied to the compressor body, which significantly reduces the vibration and noise during compressor operation, improves the compressor's operating efficiency and reliability, and reduces the equipment's energy consumption and maintenance costs.

[0106] Example 3

[0107] This application also provides an air conditioner, which includes a compressor structure, and the compressor structure is the compressor structure described above.

[0108] The air conditioner adopts a compressor structure that includes the aforementioned vibration damping device, which greatly improves the overall operating environment of the equipment, reduces noise pollution to the external environment during operation, and improves the thermal management performance of the equipment. In particular, in low temperature and high humidity environments, the heating of the supporting chassis 11 avoids the problem of frost formation, enhances the applicability of the air conditioner under various harsh climatic conditions and the user experience, and reduces downtime caused by maintenance.

[0109] When the air conditioning system is not in operation, the limiting component 31 is located in a preset static position within the vibration damping housing 32. The elastic limiting structure 33 is in a natural state and is not subjected to external forces. Once the compressor starts running, it will vibrate, causing the limiting component 31 to displace along a preset direction. The displacement of the limiting component 31 occurs dynamically according to the compressor's vibration, and the preset direction usually matches the compressor's vibration direction. As the limiting component 31 displaces, the elastic limiting structure 33 begins to deform, absorbing the vibration energy transmitted from the compressor to the limiting component 31 and converting it into elastic potential energy. This process is similar to the compression of a spring, but the design of the elastic limiting structure 33 is more complex, enabling it to adapt to vibrations of different frequencies and amplitudes.

[0110] When the displacement of the limiting component 31 exceeds a certain range, the restoring force of the elastic limiting structure 33 begins to increase significantly, preventing the limiting component 31 from moving further, thereby effectively limiting the vibration amplitude of the compressor and avoiding damage to the internal structure caused by excessive vibration.

[0111] During the process of absorbing vibration energy by the elastic limiting structure 33, some of the energy is converted into heat energy. Through the design of the air guiding component 6 and the load-bearing structure 1, this heat energy can be guided and used to heat the load-bearing chassis 11, preventing frost formation in low-temperature and high-humidity environments, thereby optimizing the thermal management performance of the air conditioning system.

[0112] During air conditioner operation, the elastic limiting structure 33 dynamically adjusts its deformation according to the vibration of the compressor, continuously absorbing and converting vibration energy to maintain the stability and effectiveness of vibration reduction.

[0113] The deformation of the elastic limiting structure 33 can effectively absorb and convert the vibration energy generated by the compressor, reduce the vibration displacement of the compressor, avoid excessive internal structural stress caused by vibration, and reduce equipment damage and maintenance costs.

[0114] The elastic limiting structure 33 restricts the movement stroke of the limiting component 31, thereby controlling the vibration amplitude of the compressor, reducing the impact of vibration on the internal components of the equipment, reducing the noise caused by vibration, and improving the operating environment and user experience of the equipment.

[0115] This vibration damping device can reduce the resonance amplitude of the compressor input frequency on the fixed frequency of the pipeline, avoid resonance between the compressor and the internal pipeline, enhance the stability of the equipment, and extend the service life of the equipment.

[0116] The heat energy generated by the elastic limiting structure 33 when absorbing vibration energy is effectively used to heat the bearing chassis 11 through the design of the air guide component 6 and the bearing structure 1, which avoids the bearing chassis 11 from frosting in low humidity environment, optimizes the thermal management of the air conditioning system, and improves energy utilization efficiency.

[0117] During the packaging and transportation of air conditioners, this vibration damping device reduces compressor vibration and displacement, lowers stress during transport, and ensures equipment safety. During operation, fine-tuning further reduces operating stress, ensuring stable operation of the equipment under various working conditions.
