Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an interface connection joint, a compressor and a vehicle. Background Art

[0002] With the increasing number of compressor types on the market, compressors are increasingly used in air conditioning, refrigeration and other industrial fields, and the requirements for the pipe connections of compressors in different systems are also showing a diversified trend. At present, the connection methods between compressors and pipeline systems mainly include hose connection and hard pipe connection. The hose connection method is widely used in scenarios that require flexible connection because the hose itself has high elasticity and can tolerate positioning deviations during installation to a certain extent. However, the hose connection also has limitations such as insufficient pressure resistance and poor seismic performance, which makes it difficult to meet the needs of certain high-performance equipment.

[0003] In contrast, rigid pipe connections are widely used in systems that require high reliability and vibration resistance due to their stable structure and superior pressure resistance. However, rigid pipe connections require high installation accuracy and have a low tolerance for positioning deviations of pipeline interfaces. In the actual installation process, the connection interface between the system and the compressor often fails to align due to slight deviations in position or angle. This deviation can lead to connection failure or insufficient sealing of the joint, which can seriously affect the subsequent commissioning of the system and even reduce the reliability of equipment operation.

[0004] In the prior art, there is still a lack of an interface connection solution that can not only meet the high reliability requirements of hard pipe connection, but also tolerate pipeline interface deviation. Therefore, developing an interface connection joint for hard pipe connection to solve the connection problem between the compressor and the system caused by interface deviation has become an important issue in the technical field.

[0035] The present invention is based on the theory of eccentric adjustment and sealing design in the field of fluid mechanics and mechanical connection, and adopts an eccentric adjustment structure. By setting the two end axes of a fluid channel to a non-coaxial state, the interface connection joint can compensate for the interface positioning deviation caused by the hard pipe connection method, thereby ensuring the connectivity of the fluid channel. Specifically, the adjusting member is essentially a cam structure. Through the rotation adjustment of its eccentric part, the path of the fluid channel is changed, thereby realizing the adjustment of the relative spatial position relationship between different structural parts, so as to effectively eliminate the interface alignment problem caused by processing error or installation deviation. In the present invention, the eccentric structure of the cam-type adjusting member allows micro-displacement adjustment by changing the angle of the eccentric part, ensuring that the fluid channel interface is compensated in the radial or axial direction. This cam-based eccentric adjustment method enables the interface deviation caused by the hard pipe connection method to be flexibly dealt with during the installation process, thereby realizing the precise connection of the fluid channel. At the same time, the basic principle of the sealing design is to prevent the leakage of the fluid along the joint connection by setting a sealing structure between the contact surfaces of the components, thereby ensuring the sealing performance of the system. The present invention solves the problem of inaccurate docking caused by interface deviation in the hard pipe connection method through the organic combination of the cam-type eccentric adjustment structure and the sealing design. While achieving efficient connection of fluid channels, it ensures the sealing and mechanical stability between joints, effectively improves the connection reliability and debugging efficiency between the compressor and the pipeline system, and achieves the technical effect of interface error compensation and efficient sealing. In addition, through the application of the cam structure, the adjustment part has the advantages of simple structure, easy processing and operation, which further improves the installation convenience and applicability of the system.

[0036] Figure 1 is a cross-sectional view of an interface connection joint according to an embodiment of the present invention, Figure 2 1 is a front view and a cross-sectional view of a fixing member 100 according to an embodiment of the present invention. Figure 3 2 is a front view and a cross-sectional view of the adjusting member 200 according to an embodiment of the present invention. Figures 1 to 3As shown, the present invention provides an interface connection joint, which is used to solve the problem that the interface between the compressor and the pipeline system cannot be aligned due to the low tolerance of the positioning deviation of the hard pipe connection method. The interface connection joint of the embodiment of the present invention includes a fixing member 100 and an adjusting member 200. The fixing member 100 has a first fluid channel 110, and the second end 111 of the first fluid channel is connected to the management system, which is used to guide the fluid from the pipeline system into the interface connection joint and further flow to the compressor. The adjusting member 200 has a second fluid channel 210, and there is an offset between the axis 211a of the first end face of the second fluid channel and the axis 212a of the second end face of the second fluid channel. The design of the offset is based on the technical principle of eccentric adjustment, which is realized by the eccentric part set at the first end of the adjusting member 200, and an eccentric channel is provided in the eccentric part, the central axis of the eccentric channel does not coincide with the central axis of the eccentric part, and a step structure or a conical transition structure is formed between the eccentric channel and the second fluid channel 210, so that the fluid can transition smoothly and reduce fluid resistance. At the same time, the adjusting member 200 cooperates with the fixing member 100 through the eccentric part. During the installation process, the path of the fluid channel is changed by adjusting the position of the eccentric channel, thereby compensating for the interface deviation between the compressor and the pipeline system, achieving the alignment connection between the two, and improving the assembly accuracy and connection reliability. In addition, the design of the step structure or conical transition not only adapts to the fluid channel interface of different diameters, but also effectively improves the stability of fluid flow and reduces energy loss. The adjusting member 200 is fixedly connected to the housing of the compressor through the fixing member 100. This fixing method not only ensures the stability of the adjusting member 200, but also provides reliable support for the arrangement of the sealing structure. The sealing structure is located between the fixing member 100 and the adjusting member 200, and is used to prevent leakage of the fluid at the interface connection. Its design is based on the sealing theory, and by applying a sealing material or structure between the contact surfaces of the two, it can maintain efficient sealing under actual working conditions. The embodiments of the present invention cooperate with each other to solve the problem of interface misalignment caused by the hard pipe connection method. The fixing member 100 provides basic support and guidance; the adjusting member 200 compensates for interface deviation through eccentric design to achieve alignment connection; the sealing structure ensures the sealing of the connection. Through this structural layout, the present invention realizes efficient and stable connection between the compressor and the pipeline system.

[0037] In some optional embodiments, the fixed connection is connected by bolt connection, and the fixing member 100 is provided with a bolt through hole 120 for installing the bolt, and the housing of the compressor is provided with a screw hole in the opposite position. When the present embodiment is installed, the bolt is inserted through the bolt through hole 120, and cooperates with the screw hole on the compressor housing, and the fixing member 100, the adjusting member 200 and the compressor housing are fastened together by the principle of threaded connection. The bolt connection structure has the advantages of being simple, reliable and easy to disassemble and assemble, and is suitable for fixing scenes requiring stability and high strength. In an embodiment of the present invention, the bolt through hole 120 on the fixing member 100 can have different geometric dimensions and structures, such as a circular through hole or an elliptical long hole, to adapt to different types of bolt installation requirements. In particular, when there is a certain processing error or position tolerance at the connection part, the elliptical long hole design can improve the compatibility of the installation and further optimize the connection stability between the adjusting member 200 and the compressor housing. The preload force during the tightening process is controlled by the tightening degree of the bolt, and further, the uniformity and anti-loosening ability of the tightening force are improved by adding washers or spring washers. This design is particularly important under dynamic load environments to prevent loosening caused by vibration or temperature changes. Carbon steel, stainless steel or other high-strength alloy materials can be selected as bolt materials to meet the needs of different use environments. In addition, although bolt connection is a typical connection method, the present invention is not limited to the form of bolt connection. The connection between the fixing member 100 and the compressor housing can also be achieved by welding, snap connection or other mechanical fixing methods, and the specific selection can be adjusted according to the actual installation conditions and cost requirements. The use of bolt connection can provide a high-strength, reliable and easy-to-maintain fixing effect. The design of the bolt through hole 120 not only improves the convenience of the installation process, but also enhances the positioning accuracy of the component in actual use. Through the tightening action of the bolt, a stable and sealed connection is formed between the adjusting member 200, the fixing member 100 and the compressor housing, ensuring the reliability and service life of the system under high pressure or dynamic conditions.

[0038] In some optional embodiments, the adjusting member 200 is limited in the radial direction by bolts. Radial limitation refers to that the bolts limit the outer circumference of the adjusting member 200 to ensure that the adjusting member 200 maintains the correct position during the connection process of the fixing member 100 or the compressor housing, and prevent the failure of the interface connection or the decrease of the sealing performance due to radial displacement. The adjusting member 200 is limited in the radial direction by bolts mainly by the matching relationship between the geometric shape of the bolt and the surface of the adjusting member 200. When the bolt passes through the bolt hole 120 of the fixing member 100 and is fastened with the screw hole of the compressor housing, its circumferential structure is in close contact with the adjusting member 200, thereby limiting the displacement of the adjusting member 200 in the radial direction. This limiting method not only helps to improve the accuracy of the connection, but also prevents the adjusting member 200 from loosening due to external force or vibration during installation or operation. Further, the bolt limit can be achieved by setting an interference fit. In actual use, the fit between the bolt and the adjusting member 200 can be designed as a slight interference fit, so that the bolt can achieve radial limitation through a certain elastic deformation. Bolt limit can also be realized by multi-point limit structure. In actual use, multiple limit contact surfaces corresponding to the bolts are set on the periphery of the adjusting member 200 to improve the stability and reliability of the limit. In an embodiment of the present invention, the radial limit mode is not limited to the direct contact limit between the bolt and the adjusting member 200. For example, the limit mechanism can also be realized by elastic retaining rings, locating pins or other mechanical structures, and its specific selection can be adjusted according to actual needs and design conditions. Through radial limit, the adjusting member 200 can maintain a stable axial and circumferential position during installation and operation, effectively avoiding pipeline connection deviation or sealing failure caused by radial displacement. Compared with the design without limit, this structure significantly improves the stability and durability of the interface connection, simplifies the alignment operation during the installation process, and reduces the manufacturing and maintenance costs in practical applications. The diversity of the limit structure and the flexibility of material selection further expand the scope of application of the design, which is suitable for realizing high-precision connection between the compressor and the pipeline system under various complex working conditions.

[0039] In some embodiments, the diameter of the bolt hole 120 includes at least the diameter and offset of the bolt. In this design, the bolt hole 120 not only needs to meet the basic requirements of the bolt passing through and tightening, but also needs to provide additional space to accommodate the offset of the adjusting member 200, thereby ensuring that the adjusting member 200 can be flexibly adjusted to the ideal position during the installation process. The bolt hole 120 is usually a hole for the fastening bolt to pass through, and its diameter design must meet the bolt assembly requirements and avoid interference problems caused by insufficient hole size. In the embodiment of the present invention, the influencing factor of the offset is further added on the basis of considering the basic passability of the bolt, so that the diameter of the bolt hole 120 not only meets the basic function of fastening connection, but also can adapt to the offset of the adjusting member 200 for position adjustment. According to the design principle of the present invention, the calculation formula for the diameter d of the bolt hole 120 of the fixing member 100 is:

[0040] d=d 标准 +2r+design margin

[0041] Where: d 标准 is the size of the through hole designed according to the nominal diameter of the bolt in the conventional fixing part 100; r is the offset of the adjusting part 200; the design margin is the additional adjustment space (usually 0.3 to 0.5 mm) provided to accommodate processing errors and assembly requirements. In the embodiment of the present invention, the design of the diameter of the bolt through hole 120 is not limited to a specific size or shape. The user can adjust the shape of the through hole and the design margin according to specific usage requirements, which should still be regarded as falling within the scope of protection of the present invention. By optimizing the design of the diameter of the bolt through hole 120, the present invention successfully solves the interference problem that may arise when the eccentric structure of the adjusting part 200 is connected to the fixing part 100 in the prior art, and effectively improves the installation flexibility of the adjusting part 200. At the same time, the design significantly reduces the dependence of the assembly on processing accuracy, improves the accuracy of the interface connection, and enhances the overall stability and reliability of the interface.

[0042] In some optional embodiments, the second end of the fixing member 100 is provided with a flange structure 130, and the opening diameter of the flange structure 130 is larger than the diameter of the second fluid channel 210. Specifically, the flange structure 130 refers to a ring of annular protrusions that are arranged at the second end of the fixing member 100 and expand outward, and contacts with the second end face 212 of the second fluid channel of the adjusting member 200 to form a sealing surface of mechanical contact, and the opening diameter of the flange structure 130 is larger than the diameter of the second fluid channel 210, which is used to achieve better connection and sealing functions. The flared shape of the flange structure 130 can effectively prevent the interception between the contact surface of the fixing member 100 and the adjusting member 200, and ensure that the fluid can flow smoothly. Specifically, the opening diameter of the flange is larger than the diameter of the second fluid channel 210, so that when connected, the problem of increased resistance to fluid flow or reduced flow is avoided. At the same time, the structural design of the flange can also enhance the mechanical strength of the connection, avoid loosening or leakage of the interface under high pressure or vibration conditions, and improve the durability and reliability of the system. In specific implementation, the diameter of the flange needs to be designed according to the size of the second fluid channel 210 and the fluid circulation requirements, so that the opening diameter of the flange is at least larger than the diameter of the second fluid channel 210 to ensure smooth flow of the fluid. In addition, the design of the flange is not limited to the traditional annular structure, and flanges of different shapes can be used according to actual needs. The specific flange structure 130 can be appropriately adjusted according to the actual application scenario and fluid characteristics. In addition, the size, thickness, etc. of the flange structure 130 can also be set according to specific system requirements. By setting the flange structure 130 at the second end of the fixing member 100, the stability and sealing of the interface connection can be effectively improved, the interception phenomenon during the fluid circulation process can be prevented, and the smooth flow of the system fluid can be ensured. This design not only enhances the mechanical strength of the connecting parts and improves the pressure resistance of the interface, but also further optimizes the sealing performance, reduces the risk of fluid leakage, and improves the reliability and long-term stability of the entire system. At the same time, the introduction of the flange structure 130 can also simplify the connection process, improve assembly efficiency, and reduce the complexity of system debugging.

[0043] In some optional embodiments, the sealing structure between the fixing member 100 and the adjusting member 200 is set as a radial seal or an end seal. Among them, radial sealing means that the contact surface between the eccentric part of the first end of the adjusting member 200 and the fixing member 100 is set in the radial direction of the first fluid channel 110 or the second fluid channel 210, and sealing is achieved by setting a seal on the contact surface. Specifically, the seal is set at the matching position between the inner circumferential surface of the eccentric part and the outer wall of the fixing member 100, and the seal can be a sealing ring or other sealing structure suitable for radial sealing. End sealing is achieved by setting a sealing structure between the end face of the eccentric part of the adjusting member 200 and the end face of the fixing member 100. The sealing structure can adopt a flat sealing gasket, a metal ring seal or other structural forms suitable for end sealing. Through the above structure, the radial seal mainly relies on the elastic deformation of the seal in the radial direction to achieve the sealing effect, which is suitable for the situation where there is an annular gap between the eccentric part and the fixing member 100, ensuring that the fluid will not leak along the gap. The end seal forms a sealing effect through the contact pressure between the seal and the two end faces, which is suitable for the scene where the eccentric part and the end face of the fixed part 100 are closely matched. The radial seal and the end seal can also be set at the same time. By setting the sealing structure of the radial seal or the end seal, the leakage of the fluid between the fixed part 100 and the adjusting part 200 can be effectively prevented, the sealing performance of the fluid channel can be ensured, and the stability and reliability of the system operation can be improved. At the same time, the selective design of the sealing structure makes the present invention more flexible in application, and can select the appropriate sealing method according to the specific working conditions, thereby further optimizing the sealing effect and extending the service life.

[0044] In some optional embodiments, the sealing structure is implemented by a sealing groove and a sealing ring, wherein the sealing groove is provided on a contact surface between the fixing member 100 and the adjusting member 200. Figure 2As shown, the sealing groove 140 can be arranged on the contact surface of the fixing member 100, or on the contact surface of the adjusting member 200, or the sealing groove can be formed together at the contacting part of the two. The cross-sectional shape of the sealing groove can be rectangular, trapezoidal, semicircular or other shapes suitable for embedding the sealing ring. The sealing ring embedded in the sealing groove can be an O-ring, a square sealing ring, a V-ring or other structural forms suitable for fluid sealing. The material of the sealing ring can be selected according to the use conditions. For example, rubber (such as nitrile rubber, fluororubber), polytetrafluoroethylene (PTFE), metal sealing ring, etc. can be used to meet the sealing requirements of different temperatures, pressures and medium environments. In a specific embodiment, the sealing ring is embedded in the sealing groove to form a sealing area between the contact surfaces of the fixing member 100 and the adjusting member 200. When the adjusting member 200 and the fixing member 100 are installed by matching, the sealing ring undergoes slight elastic deformation under the action of pressure, thereby producing a sealing effect between the contact surfaces to prevent leakage of the fluid medium. In addition, in some optional embodiments, a double-pass sealing ring can be provided in the sealing groove to improve the reliability and redundancy of the seal; or a pre-pressed seal can be achieved through an interference fit between the sealing ring and the sealing groove to further improve the sealing effect. By adopting a sealing groove in combination with a sealing ring, efficient sealing between the fixing member 100 and the adjusting member 200 is achieved, effectively preventing leakage of the fluid between the contact surfaces, and improving the reliability of the sealing structure. At the same time, the structure is simple in design, easy to process and install, and can flexibly select the shape and material of the sealing ring according to the actual use environment to adapt to the sealing requirements under different pressure, temperature and medium conditions. In addition, by providing a sealing groove between the contact surfaces, the sealing ring can have a better positioning effect, avoiding displacement of the sealing ring during installation and use, and further improving the stability and durability of the sealing structure.

[0045] In some optional embodiments, the material of the adjusting member 200 is metal or high-strength plastic, and the material of the fixing member 100 is metal. The adjusting member 200 is a component for realizing the connection and adjustment of the fluid channel between the compressor and the pipeline system, and its function is to compensate for the pipeline alignment problem caused by installation error or system deviation. In an embodiment of the present invention, the material of the adjusting member 200 can be a metal material such as aluminum alloy, stainless steel, etc. The metal material has high strength, rigidity and corrosion resistance, and is suitable for applications that need to withstand high pressure or harsh environments. The metal adjusting member 200 can ensure the stability and durability of the connection part, and avoid connection failure due to corrosion or deformation during long-term use. The material of the adjusting member 200 can also be high-strength plastic, such as glass fiber reinforced plastic, polycarbonate, polyamide, etc., which have high tensile strength, fatigue resistance and low cost engineering plastics. These materials have better processing performance, light weight, low cost, and are suitable for application scenarios with requirements for weight and cost while maintaining a certain strength. High-strength plastics also have a certain chemical corrosion resistance and are suitable for applications in certain special fluids or environments. The fixing part 100 is connected to the pipeline system and is used to fix the adjusting part 200 to the compressor housing, so its material needs to have high mechanical strength and corrosion resistance. Metal materials, such as steel, stainless steel, aluminum alloy, etc. When the fixing part 100 made of metal material is connected to the adjusting part 200, it can provide strong mechanical support to ensure that the system works stably for a long time and avoid loosening of the interface or failure of the seal due to material fatigue or deformation. In addition, metal materials usually also have good thermal conductivity, which can effectively dissipate heat during the operation of the compressor to prevent overheating and damage to components. In different application scenarios, the materials of the adjusting part 200 and the fixing part 100 can be selected according to actual needs. If in a low-pressure environment that is sensitive to cost, a high-strength plastic adjusting part 200 can be selected, while in a high-temperature or high-pressure environment, a metal adjusting part 200 is more suitable. At the same time, when the fixing part 100 is subjected to a large external force, a high-strength metal material should be preferably selected to improve the stability of the connection part. By selecting metal or high-strength plastic as the adjusting member 200 and metal material as the fixing member 100, the present invention provides an interface connection joint that can work effectively under different working conditions. The selection of metal material ensures that the connection part has high strength, corrosion resistance and long-term stability, while the selection of high-strength plastic reduces the weight and manufacturing cost of the component while maintaining good mechanical properties. This design can ensure the stability and sealing of the interface connection while meeting the requirements of different working environments, avoiding interface leakage, deformation or connection failure caused by improper material selection, thereby improving the performance and reliability of the entire system.

[0046] In some optional embodiments, the offset is 2 mm to 4 mm. The offset refers to the offset between the axis 211a of the first end face of the second fluid channel in the adjusting member 200 and the axis 212a of the second end face of the second fluid channel. Among them, the first end face 211 of the second fluid channel is a cross section connected to the fluid channel interface of the compressor housing, and the second end face 212 of the second fluid channel is the end face at the bottom of the eccentric groove. The offset in the embodiment of the present invention is used in the design to compensate for the misalignment of the pipeline interface between the compressor and the pipeline system due to installation error, self-processing error, assembly work difference or other factors. Generally, an offset of 2 mm to 4 mm can effectively alleviate the slight deviation that may occur during the actual installation process, thereby ensuring that the connection joint can work stably. In actual use, the offset is designed to be 2 mm to 4 mm, and the specific value can be adjusted according to the specifications of different compressors and pipeline systems. In some application scenarios with high precision requirements, a smaller offset (for example, 2 mm) may be selected to ensure higher alignment accuracy. For some occasions where large installation errors are allowed, the offset can also be appropriately increased to 4 mm to ensure that a certain alignment error can be tolerated. In the present embodiment, the offset of 2 mm to 4 mm is a typical range of the design, but it is not an absolute limitation. The specific offset can be flexibly adjusted according to actual needs and system accuracy requirements. For example, under some relatively loose installation conditions, the offset can be appropriately increased, even up to 5 mm or higher. By designing an offset of 2 mm to 4 mm in the adjustment member 200, the present invention can effectively solve the problem of misalignment of the pipeline docking caused by the installation error between the compressor and the pipeline system. The design within the offset range can not only tolerate the positioning error in practical applications, but also ensure the smooth flow of the fluid, avoiding the problem of pipeline leakage or poor fluid flow caused by misalignment in the traditional hard pipe connection method. Through this design, the installation process becomes more flexible, reduces the strict requirements for installation accuracy, and thus improves the reliability and production efficiency of the entire system.

[0047] Figure 4 Schematic diagram of a compressor according to an embodiment of the present invention. Figure 4As shown, an embodiment of the present invention also provides a compressor, including a shell assembly 300, the above-mentioned interface connection joint, a fluid interface is provided on the shell assembly 300, and the interface connection joint is fixedly connected to the shell assembly 300 and connects the fluid interface with the pipeline system. The interface connection joint effectively solves the problems of difficult installation and unstable connection caused by misalignment of the pipeline interface in the traditional hard pipe connection by using the above-mentioned interface connection scheme. The interface connection joint is used to connect the compressor and the pipeline system. This connection usually occurs between the air intake, exhaust port and system hard pipe of the compressor. The compressor is connected to the pipeline system through the fluid interface to transmit gas or liquid fluid. The connection joint plays a role of fluid guidance in this process, ensuring that the gas or liquid can flow stably from the compressor into the pipeline system, and can withstand the pressure fluctuations that may occur in the system. In an embodiment of the present invention, the shell assembly 300 of the compressor is connected to the fixing member 100 of the interface connection joint by a mechanical fixing method. The shell assembly 300 is usually the outer shell of the compressor, providing mechanical support and protection. A fluid interface is provided on it, and the fluid is connected to the pipeline system through these interfaces. The housing assembly 300 in this feature refers to the various parts that constitute the compressor housing, including the frame and housing that support the internal components of the compressor. Through this design, the connection between the compressor housing and the interface connection joint can form a reliable fluid channel, thereby effectively transmitting gas or liquid. In the present invention, the interface connection joint and the housing assembly 300 of the compressor can be connected by a fixed connection method that is compressed by the fixing member 100. The fixed connection can also be achieved by bolt connection, welding or other suitable mechanical connection methods. This connection method ensures that the interface connection joint and the compressor housing remain in a stable fixed state to prevent the connection from loosening due to external force or system vibration. This design method effectively improves the reliability of the connection and avoids leakage problems caused by loose connections. The fluid interface of the interface connection joint is docked with the fluid interface of the compressor housing assembly 300, and the fluid output of the compressor is connected to the output end or input end of the pipeline system through the interface. These interfaces usually adopt a sealing structure, such as a sealing groove with a sealing ring to ensure that the fluid does not leak during the flow process. The precise docking of the fluid interface is crucial to improving the operating efficiency of the system and ensuring the safe transmission of the fluid. This design can not only reduce the difficulty of installation, but also improve the sealing and reliability of the overall system. The design of the above-mentioned interface connection joint can tolerate deviations within a certain range, and with the help of the adjustment member 200, the problem caused by the misalignment between the compressor suction and exhaust ports and the pipeline interface can be effectively solved. Specifically, the adjustment member 200 can adjust the position of the connection joint according to the actual installation situation through the offset in the design, so that the pipeline system and the compressor can be smoothly connected, thereby avoiding the problem of unstable connection or leakage caused by position deviation.

[0048] An embodiment of the present invention also provides a vehicle, including the compressor of any of the above embodiments. The vehicle may also include a refrigeration system, the refrigeration system includes a compressor, and the refrigeration system is used to provide cold air or hot air into the vehicle body, thereby ensuring the comfort of the environment inside the vehicle.

[0049] The present invention proposes an improved technical solution to the problems existing in the prior art. Through the technical solution of the present invention, the connection between the compressor and the piping system becomes more flexible and efficient, and can effectively overcome the problems caused by installation errors and inaccurate positioning in traditional hard pipe connections. The design of the interface connection joint enables the system to tolerate a certain docking deviation, ensuring that the system can operate normally under various practical conditions. Due to the designed offset and sealing structure, the connection between the piping system and the compressor has higher stability and reliability, avoiding problems such as leakage and looseness, and improving the overall performance and operating efficiency of the system.
