Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a vibration damping device and an air conditioner. Background Technology

[0002] In the automotive industry, the vehicle's air conditioning system is a key component for enhancing driving comfort, and its design and installation directly impact the vehicle's overall performance and user experience. Traditionally, vehicle air conditioning units are mostly designed and installed on the roof of the vehicle. This layout considers both space utilization efficiency and facilitates heat exchange with the outside air. However, this installation method places specific requirements on the layout of the internal components of the air conditioning system, especially the compressor.

[0003] As the core power source of a vehicle's air conditioning system, the compressor's structural design must balance efficiency and stability. Currently, horizontal compressors are commonly used in the industry, primarily because they effectively lower the vehicle's overall center of gravity, enhance driving stability, and reduce the risk of roll. Horizontal compressors are typically fixed to the air conditioning unit's base plate, which is usually a large, thin-plate structure to ensure sufficient support area and distribute the load generated during compressor operation.

[0004] However, while this design brings structural advantages, it also introduces new challenges. Compressors inevitably vibrate during operation, especially under specific frequencies or load conditions, where the vibration amplitude can increase significantly. Because the air conditioning unit floor is directly connected to the roof, and the floor itself is a thin plate structure lacking sufficient damping characteristics, the vibrations generated by the compressor are easily transmitted directly to the roof, triggering low-frequency resonance in the roof floor. This low-frequency vibration not only reduces the durability of the vehicle structure, but more importantly, it generates uncomfortable low-frequency noise inside the passenger compartment, severely affecting passenger comfort and potentially interfering with the driver's attention, increasing driving safety hazards.

[0005] To address this issue, some manufacturers have adopted a symmetrically distributed twin-cylinder compressor structure in existing technologies. This symmetrical twin-cylinder layout can mitigate some vibrations and reduce their transmission to the roof. While effective to a certain extent, this method significantly increases the compressor's manufacturing costs, including material costs, processing costs, and design complexity. This poses a significant obstacle for cost-effective automakers.

[0006] Therefore, how to effectively reduce compressor vibration and thus reduce low-frequency noise problems by optimizing the vibration reduction structure design while maintaining the cost advantage of single-cylinder compressors has become an important research direction in the current design of vehicle air conditioning systems. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a vibration reduction device and an air conditioner.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] In a first aspect, this utility model provides a vibration damping device, including: a base plate, a vibration damping mechanism, a bracket, and a compressor body. The compressor body is connected to the bracket. One end of the vibration damping mechanism is connected to the base plate, and the other end is connected to the bracket. The vibration damping mechanism includes a long locking component, a short locking component, and a support plate. The long locking component is connected to the outer end of the bracket through the support plate, and the short locking component is connected to the inner end of the bracket through the support plate, so as to form an overall vibration damping structure.

[0010] In one specific embodiment, the long locking assembly includes a lower vibration damper, an upper vibration damper, and a locking nut. The base plate is connected to a long screw rod. The upper vibration damper and the lower vibration damper are respectively sleeved on the upper and lower ends of the long screw rod. The support plate is located between the upper vibration damper and the lower vibration damper. The bracket is connected to the upper vibration damper. The locking nut is located above the upper vibration damper and connected to the long screw rod.

[0011] In one specific embodiment, the lower damping member is provided with a stepped bearing surface, which abuts against the lower end surface of the support plate.

[0012] In one specific embodiment, the lower damping member has a protrusion extending upward from the center of the stepped bearing surface, the protrusion passing through the support plate and connected to the upper damping member.

[0013] In one specific embodiment, the bottom of the upper damping member is provided with a stepped hole, which is adapted to the protrusion.

[0014] In one specific embodiment, the upper damping member is provided with a circular stepped surface, which abuts against the lower end surface of the bracket.

[0015] In one specific embodiment, the upper damping member is further provided with a flange above the circular stepped surface, and the flange is connected to the upper end surface of the bracket.

[0016] In one specific embodiment, the short locking assembly includes a short screw, an upper buffer pad, and a lower buffer pad. The support plate is located between the upper buffer pad and the lower buffer pad. The short screw passes through the lower buffer pad, the support plate, and the upper buffer pad from bottom to top and is connected to the bracket.

[0017] In one specific embodiment, the short screw includes a nut, and a gap is formed between the nut and the lower buffer pad.

[0018] Compared with existing technologies, the vibration damping device of this utility model has the following advantages: By setting a unique vibration damping mechanism including a long locking component, a short locking component, and a support plate, it achieves multi-path absorption and dispersion of compressor vibration energy. The long locking component and the short locking component are respectively connected to the outer and inner ends of the bracket, forming an internal and external synergistic vibration damping mechanism, which can more comprehensively cover vibrations of different frequencies and amplitudes generated during compressor operation, effectively reducing the transmission efficiency of vibration to the base plate, and thus significantly reducing low-frequency resonance phenomena. In addition, while maintaining the cost advantage of single-cylinder compressors, a similar vibration damping effect is achieved through optimized vibration damping structure design. The design of the vibration damping mechanism cleverly utilizes the space layout, eliminating the need for additional compressor cylinders or complex transmission mechanisms, thereby effectively controlling manufacturing costs while ensuring vibration damping performance and improving the product's market competitiveness.

[0019] Secondly, this utility model embodiment provides an air conditioner, including the vibration damping device described above.

[0020] Compared with existing technologies, the beneficial effects of this air conditioner are as follows: By setting up a vibration damping device and a unique vibration damping mechanism including a long locking component, a short locking component, and a support plate, multi-path absorption and dispersion of compressor vibration energy are achieved. The long locking component and the short locking component are respectively connected to the outer and inner ends of the bracket, forming an internal and external synergistic vibration damping mechanism, which can more comprehensively cover vibrations of different frequencies and amplitudes generated during compressor operation, effectively reducing the transmission efficiency of vibration to the base plate, and thus significantly reducing low-frequency resonance phenomena. In addition, while maintaining the cost advantage of single-cylinder compressors, a similar vibration damping effect is achieved through optimized vibration damping structure design. The design of the vibration damping mechanism cleverly utilizes the space layout, eliminating the need for additional compressor cylinders or complex transmission mechanisms, thereby effectively controlling manufacturing costs while ensuring vibration damping performance and improving the product's market competitiveness.

[0035] See Figures 1 to 3 As shown, this utility model discloses a specific embodiment of a vibration damping device, including: a base plate 10, a vibration damping mechanism 20, a bracket 30, and a compressor body 40. The compressor body 40 is connected to the bracket 30. One end of the vibration damping mechanism 20 is connected to the base plate 10, and the other end is connected to the bracket 30. The vibration damping mechanism 20 includes a long locking component 21, a short locking component 22, and a support plate 23. The long locking component 21 is connected to the outer end of the bracket 30 through the support plate 23, and the short locking component 22 is connected to the inner end of the bracket 30 through the support plate 23 to form an overall vibration damping structure.

[0036] Specifically, there are two brackets 30, which are respectively connected to the front and rear ends of the compressor body 40. The compressor body 40 and the brackets 30 are welded to form an integral structure. Each set of vibration damping mechanisms 20 corresponds to one bracket 30. Each set of vibration damping mechanisms 20 includes two long locking components 21, two short locking components 22, and a support plate 23. The two long locking components 21 are respectively connected to the outer ends of both sides of the bracket 30, and the two short locking components 22 are connected to the inner ends of both sides of the bracket 30. A total of four long locking components 21 are evenly distributed on the base plate 10.

[0037] More specifically, the compressor body 40 is securely fixed between two brackets 30 using a welding process, forming a stable integrated structure. These two brackets 30 are located at the front and rear ends of the compressor body 40, respectively, providing a stable support foundation for the subsequent installation of the vibration damping mechanism 20. Furthermore, the welding connection ensures sufficient connection strength between the compressor body 40 and the brackets 30 to withstand various dynamic loads generated during compressor operation. For each bracket 30, a corresponding set of vibration damping mechanisms 20 is installed. Each set of vibration damping mechanisms 20 includes two long locking components 21, two short locking components 22, and a support plate 23. During installation, the support plate 23 is first positioned in the appropriate location on the bracket 30. As a key component connecting the long locking components 21, short locking components 22, and bracket 30, the shape and size of the support plate 23 are precisely designed according to the structure of the bracket 30 to ensure a good fit.

[0038] In addition, two long locking components 21 are connected to the outer ends of both sides of the bracket 30. The length and structure of the long locking components 21 are carefully designed to effectively absorb and disperse the large-amplitude vibration energy generated during compressor operation. Through the connection between the support plate 23 and the outer end of the bracket 30, the long locking components 21 can transfer the vibration energy to the base plate 10 and attenuate it to a certain extent during the transfer. At the same time, two short locking components 22 are connected to the inner ends of both sides of the bracket 30. The short locking components 22 are mainly used to suppress the high-frequency, small-amplitude vibration generated by the compressor. They work together with the long locking components 21 to form a multi-layered vibration reduction system. The short locking components 22 are tightly connected to the inner end of the bracket 30 through the support plate 23, further enhancing the vibration reduction mechanism 20's ability to handle different types of vibration. In addition, the four long locking components 21 are evenly distributed on the base plate 10. This even distribution design ensures that the vibration energy generated by the compressor during operation is evenly transferred to the base plate 10, avoiding damage to the base plate 10 or uneven vibration reduction effect due to excessive local stress. Meanwhile, the evenly distributed long locking components 21 help to form a stable support system, improving the stability and reliability of the entire vibration damping device.

[0039] In other words, by setting up a unique vibration damping mechanism 20 that includes a long locking component 21, a short locking component 22, and a support plate 23, multi-path absorption and dispersion of compressor vibration energy are achieved. The long locking component 21 and the short locking component 22 are connected to the outer and inner ends of the bracket 30, respectively, forming a coordinated internal and external vibration damping mechanism. This mechanism can more comprehensively cover vibrations of different frequencies and amplitudes generated during compressor operation, effectively reducing the transmission efficiency of vibration to the base plate 10, and thus significantly reducing low-frequency resonance. In addition, while maintaining the cost advantage of a single-cylinder compressor, a similar vibration damping effect is achieved through optimized vibration damping structure design. The design of the vibration damping mechanism 20 cleverly utilizes the space layout, eliminating the need for additional compressor cylinders or complex transmission mechanisms. This effectively controls manufacturing costs while ensuring vibration damping performance, thereby improving the product's market competitiveness.

[0040] See Figures 1 to 3 As shown, in one embodiment, the long locking assembly 21 includes a lower damping member 211, an upper damping member 212, and a locking nut 213. The base plate 10 is connected to a long screw 11. The upper damping member 212 and the lower damping member 211 are respectively sleeved on the upper and lower ends of the long screw 11. The support plate 23 is located between the upper damping member 212 and the lower damping member 211. The bracket 30 is connected to the upper damping member 212. The locking nut 213 is located above the upper damping member 212 and is connected to the long screw 11.

[0041] Specifically, the lower end of the long screw 11 is securely fixed to the base plate 10 by welding. A specific length of thread is pre-installed at the upper end of the long screw 11; the precision of this thread must meet design requirements to ensure accurate fit with subsequent components. Furthermore, the upper damping component 212 and the lower damping component 211 are made of suitable elastic materials, such as rubber or spring steel, according to their damping performance and structural requirements. The lower damping component 211 is slipped onto the upper end of the long screw 11, allowing it to rest stably on the base plate 10, ensuring a tight fit between the lower damping component 211, the base plate 10, and the long screw 11. Next, the support plate 23 is placed on the lower damping component 211, and then the upper damping component 212 is slipped onto the long screw 11 and placed on the support plate 23, ensuring a tight fit between the upper damping component 212 and the support plate 23. The bracket 30 is connected to the upper damping component 212 via a suitable connection method, such as snap-fit ​​or welding. After the connection between the bracket 30 and the upper damping component 212 is completed, a locking nut 213 with a washer is screwed into the upper end of the long screw 11. The use of the washer increases the contact area between the locking nut 213 and the upper damping component 212, disperses pressure, prevents damage to the upper damping component 212 during tightening, and improves the stability and reliability of the connection. Finally, the locking nut 213 and the thread at the upper end of the long screw 11 are tightly engaged, firmly locking the upper damping component 212, the support plate 23, the lower damping component 211, the base plate 10, and the bracket 30 together to form a vibration damping structure.

[0042] In other words, the long locking assembly 21 achieves a multi-layered vibration reduction effect through the combined design of the upper vibration damper 212 and the lower vibration damper 211. The upper vibration damper 212 is in direct contact with the bracket 30, which can initially absorb and disperse the large-amplitude vibration energy transmitted from the compressor, reducing the direct impact of vibration on the support plate 23. The lower vibration damper 211 further refines the vibration after it has been attenuated by the upper vibration damper 212, especially providing better suppression for high-frequency, small-amplitude vibrations. This double-layer vibration reduction structure can cover a wider range of vibration frequencies, significantly improving the vibration reduction efficiency of the entire vibration reduction device and effectively reducing the vibration and noise generated by the compressor operation. In addition, the long screw 11, as the core support component of the entire long locking assembly 21, is firmly fixed to the base plate 10 by welding, providing a stable foundation for the upper components. The locking nut 213 engages with the threaded upper end of the long screw 11 to secure the upper vibration damper 212, support plate 23, and bracket 30 together, forming a unified structure. This connection method offers high strength and stability, capable of withstanding various dynamic loads generated during compressor operation, such as vibration and impact. This ensures the vibration damping device will not loosen or detach during long-term use, guaranteeing reliable operation of the compressor system. Furthermore, adjusting the tightness of the locking nut 213 changes the preload of the upper vibration damper 212. Changes in preload affect the stiffness and vibration damping performance of the upper vibration damper 212, allowing for flexible adjustment of the device's performance based on different compressor models, operating conditions, and vibration damping requirements. This adjustability makes the vibration damping device highly adaptable, meeting the needs of various scenarios and enhancing the product's versatility and market competitiveness.

[0043] See Figures 2 to 3 As shown, in one embodiment, the lower damping member 211 is provided with a stepped bearing surface 2111, which abuts against the lower end surface of the support plate 23.

[0044] Specifically, a stepped bearing surface 2111 is designed at the top of the lower damping component 211. This stepped bearing surface 2111 is designed in a circular shape, and its diameter is optimized and determined according to the size of the support plate 23 and the load-bearing capacity of the lower damping component 211 itself. When assembling the vibration damping device, the four lower damping components 211 are first fitted onto the long screw 11 in predetermined positions to ensure even distribution and provide stable support for subsequently installed components. Next, the support plate 23 is placed on the lower damping components 211, ensuring that the lower end face of the support plate 23 accurately abuts against the circular stepped bearing surface 2111 of the lower damping component 211. During placement, care must be taken to adjust the position of the support plate 23 to ensure that both lower damping components 211 can effectively contact the support plate 23 and jointly bear the weight of the support plate 23 and the components above it. Afterwards, following the normal assembly process, the upper vibration damping component 212, the connecting bracket 30, and other components are installed in sequence, and the long screw 11 is locked by the locking nut 213.

[0045] In other words, the circular stepped bearing surface 2111 of the lower damping component 211 provides a precise support and positioning point for the support plate 23. During assembly, the lower end face of the support plate 23 abuts tightly with the stepped bearing surface 2111, ensuring that the support plate 23 is accurately installed in the predetermined position and avoiding structural instability caused by installation deviation. Simultaneously, the two lower damping components 211 jointly support the support plate 23 through the stepped bearing surface 2111, evenly distributing the weight of the compressor and its related components onto each lower damping component 211. This allows each lower damping component 211 to fully utilize its load-bearing capacity, ensuring sufficient stability of the entire vibration damping device when subjected to various dynamic loads during compressor operation and effectively preventing structural damage or decreased vibration damping effect due to excessive local stress. Furthermore, the abutment design between the circular stepped bearing surface 2111 and the lower end face of the support plate 23 increases the contact area between the lower damping component 211 and the support plate 23. A larger contact area means that vibration energy can be more evenly distributed to the lower damping component 211 during vibration transmission, allowing the lower damping component 211 to absorb and attenuate vibrations more effectively. Furthermore, this tight contact reduces energy loss and reflection during vibration transmission, minimizing additional vibration and noise caused by gaps or looseness between components, further improving the overall vibration damping performance of the device. Additionally, the stable contact between the stepped bearing surface 2111 and the lower end face of the support plate 23 reduces relative movement and friction between components. During long-term compressor operation, this stable connection effectively avoids wear and loosening of components caused by vibration, extending the service life of the lower damping component 211, support plate 23, and other related components. Simultaneously, the stable structure helps maintain the performance stability of the vibration damping device, ensuring it continues to provide good vibration damping throughout its service life, improving the reliability and durability of the entire compressor system.

[0046] See Figures 2 to 3 As shown, in one embodiment, the lower damping member 211 has a protrusion 2112 extending upward from the center of the step bearing surface 2111, and the protrusion 2112 passes through the support plate 23 and is connected to the upper damping member 212.

[0047] Specifically, a protrusion 2112 is designed at the center of the stepped bearing surface 2111 of the lower damping component 211. The height, diameter, and other parameters of the protrusion 2112 are precisely designed according to the matching requirements with the support plate 23 and the upper damping component 212. For example, the height of the protrusion 2112 must ensure that it can pass smoothly through the support plate 23 and effectively connect with the upper damping component 212, while the diameter needs to take into account factors such as the fitting clearance with the opening on the support plate 23 and its own strength.

[0048] In other words, the protrusion 2112 passes through the support plate 23 and connects to the upper vibration damper 212, forming a constrained fit. This constraint makes the lower vibration damper 211, the support plate 23, and the upper vibration damper 212 a relatively fixed whole. During compressor operation, it can effectively resist forces and moments generated in various directions due to vibration, preventing relative displacement and loosening between components. For example, when the compressor vibrates horizontally, the connection between the protrusion 2112 and the support plate 23 and the upper vibration damper 212 can limit the horizontal movement of the support plate 23, ensuring the stability of the entire vibration damping structure. In addition, the four lower vibration dampers 211, through the constrained fit of the protrusion 2112, can more evenly distribute the weight and vibration energy of the compressor and its related components, further improving the load-bearing capacity and stability of the entire vibration damping device, ensuring stable operation of the compressor under various operating conditions. Furthermore, the presence of the protrusion 2112 increases the connection stiffness between the lower damper 211 and the upper damper 212, making the transmission of vibration energy between them more direct and effective. During vibration transmission, the upper damper 212 first absorbs a portion of the vibration energy, and then rapidly transmits the remaining energy to the lower damper 211 through the protrusion 2112, where the lower damper 211 further attenuates the vibration. This synergistic effect can more comprehensively cover vibrations of different frequencies and amplitudes, improving the damping device's ability to handle various complex vibrations. Simultaneously, the constrained fit reduces gaps and friction between components, lowering vibration noise and energy loss caused by gaps, enabling the damping device to perform its damping performance more efficiently.

[0049] See Figures 2 to 3 As shown, in one embodiment, the bottom of the upper damping member 212 is provided with a stepped hole 2121, which is adapted to the protrusion 2112.

[0050] Specifically, based on the compressor's model, power, operating vibration characteristics, and the design requirements of the overall vibration damping device, and taking into account factors such as the mechanical properties and cost of the materials, the parameters of the protrusion 2112 and the stepped hole 2121 are precisely determined. For example, for compressors with higher power and higher vibration amplitude, the height and outer diameter of the protrusion 2112 extending out of the support plate 23, as well as the depth and inner diameter of the stepped hole 2121, are appropriately increased to enhance connection strength and vibration damping effect. After detailed calculation and simulation analysis, the height of the protrusion 2112 extending out of the support plate 23 is determined to be 5-10 mm, and the outer diameter to be 11-17 mm; the depth of the stepped hole 2121 is determined to be 6-12 mm, and the inner diameter to be 12-18 mm.

[0051] In other words, the stepped hole 2121 at the bottom of the upper vibration damper 212 matches the protrusion 2112 of the lower vibration damper 211, providing a clear positioning reference for the installation of the upper vibration damper 212. During assembly, the upper vibration damper 212 can be installed in the correct position quickly and accurately, avoiding structural instability caused by installation deviations and improving assembly efficiency and product quality. Furthermore, after the protrusion 2112 is inserted into the stepped hole 2121, a tight mechanical connection is formed between the two. This connection effectively restricts the movement of the upper vibration damper 212 in all directions, enhancing the structural stability of the entire vibration damping device. During compressor operation, it can withstand significant vibration and impact forces, ensuring the stable operation of the compressor and its related components and reducing problems such as component loosening and damage caused by vibration. In addition, the reasonable design of the stepped hole 2121 and the protrusion 2112 increases the connection area and connection stiffness between the upper vibration damper 212 and the lower vibration damper 211. During vibration transmission, the upper damping component 212 first absorbs a portion of the vibration energy, and then, through the tight fit between the protrusion 2112 and the stepped hole 2121, the remaining energy is more effectively transferred to the lower damping component 211. The lower damping component 211 further attenuates the vibration. This synergistic effect of upper and lower damping can more comprehensively cover vibrations of different frequencies and amplitudes, improving the overall damping effect of the damping device. In addition, the appropriate height and outer diameter of the protrusion 2112 extending from the support plate 23, as well as the depth and inner diameter of the stepped hole 2121, allow for a certain elastic deformation space when the two are connected. Under vibration, the upper damping component 212 and the lower damping component 211 can absorb and dissipate vibration energy through elastic deformation, reducing the impact of vibration on the compressor and surrounding equipment.

[0052] In one embodiment, both the upper damping member 212 and the lower damping member 211 are provided with longitudinal through holes. The upper damping member 212 and the lower damping member 211 are respectively sleeved on the upper and lower ends of the long screw 11 through the longitudinal through holes. The diameter of the longitudinal through holes is 1-2 mm larger than the outer diameter of the long screw 11 to form a clearance fit.

[0053] Specifically, the clearance fit design between the longitudinal through hole and the long screw 11 allows the upper damping component 212 and the lower damping component 211 to be easily fitted onto the long screw 11 without the need for complex tools or precise alignment operations, greatly improving installation efficiency. During assembly, operators can quickly and accurately install each component, reducing installation time and labor intensity. Furthermore, when the compressor vibrates during operation, the damping component can absorb and dissipate vibration energy through its own elastic deformation, reducing the transmission of vibration to the base plate 10. Additionally, the clearance fit between the longitudinal through hole and the long screw 11 provides sufficient space for the elastic deformation of the damping component, allowing it to more fully exert its damping effect.

[0054] See Figures 2 to 3 As shown, in one embodiment, the upper damping member 212 is provided with a circular stepped surface, which abuts against the lower end surface of the bracket 30.

[0055] Specifically, the circular stepped surface abuts against the lower end face of the bracket 30, supporting the lower end face of the bracket 30. In other words, this abutment design between the circular stepped surface and the lower end face of the bracket 30 ensures that the weight of the bracket 30 is evenly distributed on the upper damping component 212. The circular shape is isotropic; regardless of the direction of force applied to the bracket 30 in the horizontal direction, the circular stepped surface provides stable support, preventing damage to the upper damping component 212 or tilting of the bracket 30 due to excessive localized stress, thus improving the stability and reliability of the entire damping device. Furthermore, the tight abutment effectively restricts the displacement of the bracket 30 in both the vertical and horizontal directions. During compressor operation, the vibrations and impacts generated will not easily cause the bracket 30 to move, which is beneficial for the normal operation and performance of the compressor. In addition, the stable abutment reduces the relative movement and friction between the bracket 30 and the upper damping component 212, reducing component wear and fatigue damage caused by long-term vibration and friction. In addition, the upper damping component 212 and the bracket 30 work in good coordination, which can distribute stress more evenly and avoid local stress concentration, thereby extending the service life of the entire damping device.

[0056] See Figures 2 to 3 As shown, in one embodiment, the upper damping member 212 is provided with a flange 2122 above the circular step surface, and the flange 2122 is connected to the upper end surface of the bracket 30.

[0057] Specifically, the flange 2122 is connected to the upper end face of the bracket 30 and forms an upper and lower constraint mechanism with the circular stepped surface supporting the lower end face of the bracket 30. This dual constraint effectively limits the vertical displacement of the bracket 30, preventing the compressor from bouncing up and down due to vibration during operation, improving the structural stability of the entire vibration damping device, and ensuring stable operation of the compressor. Furthermore, in the horizontal direction, the connection between the flange 2122 and the upper end face of the bracket 30 increases the structure's resistance to tipping over. When the compressor is subjected to horizontal impact or vibration, the flange 2122 provides resistance, preventing the bracket 30 from tipping over and ensuring the safety of the vibration damping device and the compressor. Additionally, the presence of the flange 2122 increases the contact area and elastic buffer zone between the upper vibration damping component 212 and the bracket 30. When the compressor vibrates, more rubber material participates in elastic deformation, absorbing and dissipating more vibration energy, thereby further reducing the transmission of vibration to the base plate 10 and improving the vibration damping effect.

[0058] See Figures 1 to 3As shown, in one embodiment, the short locking assembly 22 includes a short screw 221, an upper buffer pad 222 and a lower buffer pad 223, the support plate 23 is located between the upper buffer pad 222 and the lower buffer pad 223, and the short screw 221 passes through the lower buffer pad 223, the support plate 23 and the upper buffer pad 222 in sequence from bottom to top and is connected to the bracket 30.

[0059] Specifically, the short screw 221 is threaded and is tightened by engaging with the corresponding threaded hole on the bracket 30. The upper buffer pad 222 and the lower buffer pad 223 are used for vibration buffering between the bracket 30 and the support plate 23, while distributing the vibration reduction and absorption effects to the upper vibration damping component 212.

[0060] More specifically, the specifications of the short screw 221 are determined based on the overall dimensions and load-bearing requirements of the vibration damping device. For example, considering the weight of the compressor and bracket 30, a screw with a suitable diameter and length is selected, generally with a diameter between M6 and M12. The length is determined based on the total thickness of the support plate 23, upper buffer pad 222, lower buffer pad 223, and bracket 30, ensuring smooth passage through all components and sufficient threaded connection length. Furthermore, rubber materials with good elasticity, wear resistance, and aging resistance, such as silicone rubber and nitrile rubber, are selected. These materials can undergo elastic deformation under vibration and pressure, effectively absorbing and attenuating vibration energy. The thickness is determined based on vibration damping requirements and space constraints, typically between 3 and 10 mm.

[0061] In other words, the upper buffer pad 222 and the lower buffer pad 223 are made of rubber material, which has good elasticity. When the support 30 is subjected to vibration from the compressor, the vibration energy is transmitted to the upper buffer pad 222 and the lower buffer pad 223. The rubber material undergoes elastic deformation, absorbing and dissipating some of the vibration energy, thereby reducing the transmission of vibration to the support plate 23, reducing the vibration amplitude of the entire vibration damping device, and providing a more stable operating environment for the compressor. In addition, the upper buffer pad 222 and the lower buffer pad 223 share the vibration damping and absorption functions with the upper vibration damping component 212. They work together with the upper vibration damping component 212 to form a multi-layer vibration damping system. The upper vibration damping component 212 mainly bears the buffering of larger amplitude vibrations, while the upper buffer pad 222 and the lower buffer pad 223 further attenuate the remaining small vibrations, improving the vibration damping effect of the entire vibration damping device and effectively reducing the impact of noise and vibration generated by the compressor operation on the surrounding environment. In addition, the short screw 221 is threaded and is tightened by engaging with the corresponding threaded hole on the bracket 30. This threaded connection method features a firm connection and convenient disassembly. During compressor operation, the short screw 221 can withstand the tensile and shear forces between the bracket 30 and the support plate 23, ensuring that the relative position between the support plate 23 and the bracket 30 is fixed and will not loosen or separate due to vibration, thus ensuring the structural stability of the entire vibration damping device. Furthermore, the upper buffer pad 222 and the lower buffer pad 223 not only serve a buffering function but also position the support plate 23 during assembly. They clamp the support plate 23 in the middle, preventing it from shifting horizontally and further enhancing the connection and fixing effect of the short locking assembly 22. In addition, due to the elastic buffering effect of the upper buffer pad 222 and the lower buffer pad 223, the direct impact and friction between the bracket 30 and the support plate 23 are reduced, reducing component wear. During long-term operation, this buffering effect can effectively protect the surfaces of the support plate 23 and the bracket 30, extending their service life and reducing equipment maintenance costs. The overall design of the short locking assembly 22 can adapt to the vibration environment during compressor operation. The robust connection of the short screw 221 and the elastic buffering of the upper buffer pad 222 and lower buffer pad 223 combine to ensure that the entire assembly maintains stable performance during vibration and will not be damaged by frequent vibration, thereby improving the reliability and durability of the vibration damping device.

[0062] See Figure 2 As shown, in one embodiment, the short screw 221 includes a nut, and a gap is formed between the nut and the lower buffer pad 223.

[0063] Specifically, the gap between the nut and the lower buffer pad 223 provides additional elastic deformation space for the lower buffer pad 223. When the support 30 is subjected to vibration, the lower buffer pad 223 can undergo greater elastic deformation within the gap range, thereby absorbing and dissipating more vibration energy. Compared with the case without a gap, this greater deformation capacity can more effectively reduce the vibration amplitude and improve the vibration reduction effect. In addition, without a gap, the nut and the lower buffer pad 223 are in close contact, which may cause stress concentration during vibration, leading to premature local damage to the lower buffer pad 223. The existence of a gap can disperse stress, making the lower buffer pad 223 more evenly stressed, extending the service life of the lower buffer pad 223, and thus improving the reliability and stability of the entire vibration reduction device. Furthermore, during compressor operation, due to the heat generated by the current and changes in ambient temperature, components such as the short screw 221, support plate 23, and lower buffer pad 223 will undergo thermal expansion and contraction. The gap between the nut and the lower buffer pad 223 can provide a certain space for the thermal expansion of the components, avoiding mutual compression and deformation between components caused by thermal expansion. When the temperature rises, the components expand, and the gap can accommodate part of the expansion, preventing the nut from putting excessive pressure on the lower buffer pad 223; when the temperature drops, the components contract, and the gap can ensure that the components still maintain a certain contact and will not become loose.

[0064] Preferably, the gap between the nut and the lower buffer pad 223 is 2mm.

[0065] Specifically, the 2mm gap provides greater elastic deformation space for the lower buffer pad 223. When the support 30 is subjected to compressor vibration, the lower buffer pad 223 can fully undergo elastic deformation within the gap range, absorbing and dissipating more vibration energy. Compared to cases with no gap or a small gap, this more effectively reduces vibration amplitude, decreases vibration transmission to the support plate 23 and other components, and improves the overall vibration damping effect of the damping device. Furthermore, a reasonable gap design can alter the vibration transmission characteristics, allowing vibration energy to decay more smoothly during transmission. The elastic deformation of the lower buffer pad 223 within the gap acts as a buffer and isolation mechanism, preventing vibration from being transmitted in a rigid impact manner, thereby reducing the impact of vibration on the equipment and improving the stability of equipment operation. Additionally, during compressor operation, components such as the short screw 221, support plate 23, and lower buffer pad 223 will undergo thermal expansion and contraction due to heat generated by current flow and changes in ambient temperature. The 2mm gap provides some space for the thermal expansion of the component. When the temperature rises, the component expands, and the gap can accommodate some of the expansion, preventing the nut from putting excessive pressure on the lower buffer pad 223 and avoiding damage to the lower buffer pad 223 due to excessive compression. In addition, the 2mm gap provides some tolerance during installation. During assembly, even if there is a slight deviation in the position of the short screw 221, it can be adjusted through the gap to ensure that the nut can smoothly mate with the lower buffer pad 223, reducing installation difficulty and improving installation efficiency.

[0066] This utility model also discloses an air conditioner, including the vibration damping device described above.

[0067] Specifically, by setting up a vibration damping device and a unique vibration damping mechanism 20 comprising a long locking component 21, a short locking component 22, and a support plate 23, multi-path absorption and dispersion of compressor vibration energy are achieved. The long locking component 21 and the short locking component 22 are respectively connected to the outer and inner ends of the bracket 30, forming a coordinated internal and external vibration damping mechanism. This mechanism can more comprehensively cover vibrations of different frequencies and amplitudes generated during compressor operation, effectively reducing the transmission efficiency of vibration to the base plate 10, and thus significantly reducing low-frequency resonance. In addition, while maintaining the cost advantage of a single-cylinder compressor, a similar vibration damping effect is achieved by optimizing the vibration damping structure design. The design of the vibration damping mechanism 20 cleverly utilizes the space layout, eliminating the need for additional compressor cylinders or complex transmission mechanisms. This ensures vibration damping performance while effectively controlling manufacturing costs and improving the product's market competitiveness.
