Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a hydraulic compressor mount. Background Technology

[0002] In the automotive technology field, as people's demands for vehicle ride comfort and driving experience continue to increase, the noise, vibration, and harshness (NVH) performance of automobiles is receiving more and more attention. As one of the key components of a vehicle, the vibration generated during the operation of the automotive air conditioning compressor has a significant impact on the overall NVH performance of the vehicle.

[0003] In most cars, the air conditioning compressor is typically directly connected to the vehicle body. This connection method is simple in structure and low in cost, but it has significant drawbacks. The vibrations generated when the compressor is working are transmitted directly to the vehicle body without any obstruction, causing vibrations in the vehicle structure, generating noise, and seriously affecting the comfort of the occupants. Due to the lack of effective vibration damping measures, the noise inside the vehicle increases significantly during driving, especially when driving over bumpy roads or when the compressor is under high load, greatly diminishing the driving experience.

[0004] To address these issues, some high-end models have begun using pure rubber compressor mounts. Rubber itself has a certain degree of elasticity, which can absorb and buffer vibrations to some extent. Compared to direct connections, it attenuates vibration transmission, thereby reducing cabin noise levels and improving NVH performance. Relevant prior art, such as Chinese patent application "A Suspension System for an Air Compressor," application number CN202410234450.0, discloses a technology in the field of automotive suspension systems, including a hydraulic suspension and a hydraulic suspension control system. The hydraulic suspension includes a top cover, a base, and a main spring. The main spring is disposed between the top cover and the base, which are fixedly connected. The base is mounted on the vehicle body. A connecting bracket is fixed to one side of the main spring, and the connecting bracket has mounting holes for fixing to an air compressor. A storage chamber is formed inside the main spring, storing flowing liquid. A hydraulic cylinder is provided on one side of the hydraulic suspension, and a piston is installed inside the hydraulic cylinder. An inlet pipe and an outlet pipe are connected to one side of the hydraulic cylinder and the storage chamber. A hydraulic gauge is connected to the inlet pipe. A distance sensor is fixed to the right side of the piston. This device solves the current problem of not being able to distinguish whether the issue is with the installation of the hydraulic suspension or damage to the main spring inside the hydraulic suspension.

[0005] However, using pure rubber mounts also has many limitations. Under low-frequency, high-amplitude conditions, such as when a vehicle is traveling at low speeds on uneven roads, the large amplitude vibrations generated by the compressor require significant damping to effectively absorb them. Pure rubber mounts have relatively low damping, which cannot meet this requirement, resulting in a still high vibration transmission rate, and noticeable vibrations can still be felt inside the vehicle. Under high-frequency, low-amplitude conditions, such as when a vehicle is traveling at high speeds, the rubber material is prone to high-frequency hardening, increasing its elastic modulus and dynamic stiffness. This reduces the isolation effect of the mount system on high-frequency vibrations, easily triggering high-frequency resonance, further amplifying noise, and affecting the quietness of the vehicle interior. Furthermore, the structure and performance of pure rubber mounts are relatively fixed, making it difficult to flexibly adjust according to the operating conditions and configurations of different vehicle models. This results in poor adaptability to different powertrains and body structures, limiting their widespread application. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a hydraulic compressor mount that effectively absorbs low-frequency large-amplitude vibrations through hydraulic damping characteristics, reduces high-frequency stiffness to avoid resonance, and improves the NVH performance of automotive compressors.

[0007] The technical solution adopted in this application is as follows: a hydraulic compressor suspension, including a main spring assembly, a flow channel assembly, steel balls and bolts. The main spring assembly is covered by a compressor connecting bracket. A liquid filling channel is provided in the main spring assembly. The steel balls are located in the liquid filling channel and block the liquid filling channel. One end of the bolt is fixed to the main spring assembly. A flow channel assembly is provided below the main spring and is located in the compressor connecting bracket. The bottom of the main spring assembly is located in the compressor connecting bracket. The upper part of the main spring assembly extends out of the compressor connecting bracket. The main spring assembly extending out of the compressor connecting bracket includes an anti-collision pad. The anti-collision pad has an umbrella-shaped structure with an open top surface.

[0008] Compared with the prior art, the advantages of this application are that, firstly, compared with the traditional pure rubber suspension, this application can provide greater damping under low-frequency large amplitude conditions, significantly reduce the transmission of compressor vibration to the vehicle body, and improve the comfort of the occupants when the vehicle passes through bumpy roads or when the compressor is running under high load.

[0009] Secondly, hydraulic suspension, through the flow of hydraulic oil and the action of inertial channels, avoids the resonance problem caused by high-frequency hardening of rubber, allowing the suspension system to maintain good vibration isolation even under high-frequency, low-amplitude conditions. This effectively avoids high-frequency resonance, reduces the transmission of high-frequency vibrations into the vehicle interior, improves the quietness of the vehicle at high speeds, and further optimizes the driving experience for passengers.

[0010] Furthermore, the main spring assembly is encased in a compressor mounting bracket, a design that ensures a more secure connection between the main spring assembly and the compressor. The flow channel assembly is located within the compressor mounting bracket, and the bottom of the main spring assembly is situated within it. This rational layout results in a compact overall suspension system structure and tight fit between all components. This improves the reliability and lifespan of the suspension system, reduces the risk of failure due to structural loosening or hydraulic oil leakage, and lowers maintenance costs.

[0011] Finally, the peak frequency can be flexibly adjusted by changing the design of the decoupling disc in the flow channel assembly. Different vehicle models and operating conditions have different requirements for the vibration isolation performance of the compressor mount. By adjusting the design parameters of the decoupling disc, the natural frequency and damping characteristics of the mount system can be changed, making it better suited to the needs of different vehicle models and operating conditions. This makes this application more widely applicable, able to meet the personalized needs of automobiles with different powertrains and body structures for compressor mounts, improving its competitiveness in the automotive parts market, and is expected to become a key technical solution for improving the NVH performance of automotive compressors.

[0012] In some embodiments of this application, the compressor connecting bracket includes an upper housing and a lower housing. An upper mounting plate extends outward from the bottom surface of the upper housing, and a lower mounting plate extends outward from the top surface of the lower housing. The upper mounting plate and the lower mounting plate are stacked on top of each other, and both the upper mounting plate and the lower mounting plate are provided with mounting holes that are connected to the compressor.

[0013] This split-type compressor connection bracket, with its upper and lower mounting plates overlapping, not only enhances the overall structural strength of the bracket but also facilitates installation and disassembly, improving assembly efficiency. Simultaneously, the mounting holes on the upper and lower mounting plates connect to the compressor, ensuring a secure connection between the compressor and the mounting system and enhancing the overall system reliability.

[0014] In some embodiments of this application, the main spring assembly includes a main spring inner core and a rubber main spring, wherein the rubber main spring is wrapped around the main spring inner core.

[0015] The main spring assembly employs a combination structure of an inner core and a rubber main spring. The rubber main spring provides excellent elastic cushioning, while the inner core enhances the overall strength and stability of the main spring. This composite structure ensures the elastic cushioning performance of the suspension system during vibration and improves the load-bearing capacity and durability of the main spring, effectively extending the service life of the suspension system.

[0016] In some embodiments of this application, the inner core of the main spring includes a circular tube with a stepped hole along the axial direction, forming a liquid filling channel. The lower part of the bolt extends into the stepped hole, and the steel ball is located inside the stepped hole and below the bolt.

[0017] The stepped hole design within the main spring core creates a hydraulic fluid channel. Hydraulic oil flows within this channel, and the flow is effectively controlled by bolts and steel balls, thus achieving damping adjustment for vibrations. This design fully utilizes the damping characteristics of hydraulic oil, enhancing the suspension system's vibration absorption capability under low-frequency, high-amplitude conditions. Simultaneously, the steel balls seal the fluid channel, preventing hydraulic oil leakage and ensuring the normal operation of the hydraulic system.

[0018] In some embodiments of this application, the inner core of the main spring includes a disc component, which is coaxially arranged with the circular tube component and located on the outer periphery of the circular tube component.

[0019] The coaxial arrangement of the disc and tubular components increases the structural stability of the main spring core, allowing it to distribute stress more evenly when subjected to compressor vibration, reducing localized stress concentration, and thus improving the service life and reliability of the main spring core. Furthermore, the disc design provides better support for the rubber main spring, further enhancing the overall performance of the main spring assembly.

[0020] In some embodiments of this application, a conical connector extends from the lower part of the rubber main spring. The connector is located below the disc component, and the diameter of the connector gradually increases from top to bottom. The upper part of the connector is connected to the circular tube component, and the lower part of the connector is connected to the inner wall surface of the compressor connecting bracket.

[0021] The conical connector design makes the connection between the rubber spring and the compressor mounting bracket more robust. The connector diameter gradually increases from top to bottom, which better disperses stress and reduces stress concentration at the connection point, thereby improving the connection strength and reliability between the rubber spring and the mounting bracket, and enhancing the stability of the entire suspension system.

[0022] In some embodiments of this application, a buffer pad extends from the middle of the rubber main spring. The buffer pad is located on the top surface of the disc component. Multiple convex ridges are regularly arranged on the top surface of the buffer pad. The multiple convex ridges are arranged parallel to each other. There is a gap between the buffer pad and the inner wall surface of the compressor connecting bracket. A groove is opened on the surface of the buffer pad. The groove is arranged perpendicular to the convex ridges.

[0023] The design of the buffer pad further enhances the cushioning performance of the rubber spring. The raised ridges on the top surface of the buffer pad effectively disperse vibration energy and reduce vibration transmission. The groove design increases the flexibility of the buffer pad, allowing it to better adapt to different vibration conditions when compressed, further improving the vibration isolation effect of the suspension system.

[0024] In some embodiments of this application, the diameter of the anti-collision pad gradually decreases from top to bottom, and the inner wall surface of the anti-collision pad is regularly provided with raised ribs, which cover the entire inner wall surface of the anti-collision pad.

[0025] The design of the bumper pad, with its diameter gradually decreasing from top to bottom, allows for better stress dispersion upon impact, reducing damage to the main spring assembly. The raised ribs on the inner wall further enhance the structural strength and wear resistance of the bumper pad, extending its service life and better protecting the main spring assembly from external impacts.

[0026] In some embodiments of this application, the flow channel assembly includes a flow channel cover plate, a decoupling plate, a flow channel bottom plate, a cup and a base. The flow channel cover plate is connected to the flow channel bottom plate and forms a cavity inside it. The decoupling plate is installed in the cavity.

[0027] The flow channel assembly design, through the cavity formed by the flow channel cover and the flow channel base plate, provides a stable channel for the flow of hydraulic oil. The installation of the decoupling disc effectively adjusts the flow characteristics of the hydraulic oil, thereby enabling flexible adjustment of the natural frequency and damping characteristics of the suspension system. This design not only improves the vibration isolation effect of the suspension system but also enhances its adaptability to different operating conditions, improving the overall system performance and flexibility.

[0028] In some embodiments of this application, the diaphragm is installed below the flow channel base plate, the base is sleeved below the diaphragm, and the bottom of the base extends out of the compressor connecting bracket.

[0029] The installation of the hydraulic cup effectively seals the hydraulic oil, preventing leakage and ensuring the normal operation of the hydraulic system. The design of the compressor connection bracket extending from the bottom of the base provides stable support for the entire suspension system, enhancing its overall structural strength and stability, and further improving its reliability and service life.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] A hydraulic compressor mount, as described in Embodiment 1 Figures 1 to 3 As shown, the system includes a main spring assembly 1, a flow channel assembly 2, steel balls 3, and bolts 4. The main spring assembly 1 is fitted with a compressor connecting bracket 5, a structural design that makes the connection between the main spring assembly 1 and the compressor more stable. The main spring assembly 1 has a filling channel, which is sealed by the steel balls 3. One end of the bolts 4 is fixed to the main spring assembly 1. The flow channel assembly 2 is located below the main spring and is situated within the compressor connecting bracket 5. The bottom of the main spring assembly 1 is located within the compressor connecting bracket 5, and the upper part of the main spring assembly 1 extends out from the compressor connecting bracket 5. This rational layout makes the entire suspension system compact, with close cooperation between the components. This improves the reliability and service life of the suspension system, reduces the risk of failure due to structural loosening or hydraulic oil leakage, and reduces maintenance costs. The main spring assembly 1 extending out from the compressor connecting bracket 5 includes an anti-collision pad 7, which has an umbrella-shaped structure with an open top surface.

[0037] Compared to traditional pure rubber mounts, this application provides greater damping under low-frequency, high-amplitude conditions, significantly reducing the transmission of compressor vibration to the vehicle body and improving passenger comfort when the vehicle travels over bumpy roads or when the compressor is under high load. The hydraulic mount, through the flow of hydraulic oil and the action of inertial channels, avoids the resonance problem caused by high-frequency hardening of rubber, allowing the mount system to maintain good vibration isolation even under high-frequency, low-amplitude conditions. This effectively avoids high-frequency resonance, reduces the transmission of high-frequency vibration to the vehicle interior, improves vehicle quietness at high speeds, and further optimizes the driving experience for passengers.

[0038] The flow channel assembly 2 includes a flow channel cover plate 22, a decoupling disc 23, a flow channel base plate 24, a piston cup 25, and a base 26. The flow channel cover plate 22 and the flow channel base plate 24 are connected and form a cavity, within which the decoupling disc 23 is installed. The design of the flow channel assembly 2, through the cavity formed by the flow channel cover plate 22 and the flow channel base plate 24, provides a stable channel for the flow of hydraulic oil. The installation of the decoupling disc 23 effectively adjusts the flow characteristics of the hydraulic oil, thereby enabling flexible adjustment of the natural frequency and damping characteristics of the suspension system. This design not only improves the vibration isolation effect of the suspension system but also enhances its adaptability to different working conditions, improving the overall system performance and flexibility.

[0039] The piston cup 25 is installed below the flow channel base plate 24, and the base 26 is fitted below the piston cup 25, with the compressor connecting bracket 5 extending from the bottom of the base 26. The installation of the piston cup 25 effectively seals the hydraulic oil, preventing leakage and ensuring the normal operation of the hydraulic system. The design of the compressor connecting bracket 5 extending from the bottom of the base 26 provides stable support for the entire suspension system, enhancing its overall structural strength and stability, and further improving its reliability and service life.

[0040] Example 2, as Figures 1 to 5 As shown, the compressor connecting bracket 5 includes an upper housing 8 and a lower housing 9. An upper mounting plate 10 extends outward from the bottom surface of the upper housing 8, and a lower mounting plate 11 extends outward from the top surface of the lower housing 9. The upper mounting plate 10 and the lower mounting plate 11 are stacked vertically, and both the upper mounting plate 10 and the lower mounting plate 11 are provided with mounting holes 12, which connect to the compressor. This split-type compressor connecting bracket 5, through the stacked connection of the upper mounting plate 10 and the lower mounting plate 11, not only enhances the overall structural strength of the connecting bracket but also facilitates installation and disassembly, improving assembly efficiency. Simultaneously, the mounting holes 12 on the upper and lower mounting plates 11 connect to the compressor, ensuring a stable connection between the compressor and the suspension system, thus improving the reliability of the entire system.

[0041] The main spring assembly 1 includes a main spring inner core 13 and a rubber main spring 14, with the rubber main spring 14 encasing the main spring inner core 13. The main spring assembly 1 employs a combined structure of the inner core and the rubber main spring 14. The rubber main spring 14 provides excellent elastic cushioning, while the main spring inner core 13 enhances the overall strength and stability of the main spring. This composite structure ensures the elastic cushioning performance of the suspension system during vibration and improves the load-bearing capacity and durability of the main spring, effectively extending the service life of the suspension system.

[0042] The main spring core 13 includes a circular tube 15 with a stepped hole 16 along its axial direction. The stepped hole 16 forms a fluid filling channel. The lower part of the bolt 4 extends into the stepped hole 16, and the steel ball 3 is located within the stepped hole 16, below the bolt 4. The stepped hole 16 of the main spring core 13 forms a fluid filling channel, through which hydraulic oil flows. The cooperation of the bolt 4 and the steel ball 3 effectively controls the flow of hydraulic oil, thereby achieving damping adjustment for vibration. This design fully utilizes the damping characteristics of hydraulic oil, enhancing the vibration absorption capacity of the suspension system under low-frequency, high-amplitude conditions. Simultaneously, the steel ball 3 seals the fluid filling channel, preventing hydraulic oil leakage and ensuring the normal operation of the hydraulic system.

[0043] The main spring core 13 includes a disc component 17, which is coaxially arranged with the circular tube component 15 and located on the outer periphery of the circular tube component 15. The coaxial arrangement of the disc component 17 and the circular tube component 15 increases the structural stability of the main spring core 13, allowing it to distribute stress more evenly when subjected to compressor vibration, reducing local stress concentration, and thus improving the service life and reliability of the main spring core 13. Furthermore, the design of the disc component 17 also provides better support for the rubber main spring 14, further enhancing the overall performance of the main spring assembly 1.

[0044] A conical connector 18 extends from the lower part of the rubber main spring 14. The connector 18 is located below the disc component 17, and its diameter gradually increases from top to bottom. The upper part of the connector 18 connects to the circular tube component 15, and the lower part connects to the inner wall of the compressor connecting bracket 5. The conical connector 18 design makes the connection between the rubber main spring 14 and the compressor connecting bracket 5 more robust. The gradually increasing diameter of the connector 18 better disperses stress, reduces stress concentration at the connection point, thereby improving the connection strength and reliability between the rubber main spring 14 and the connecting bracket, and enhancing the stability of the entire suspension system.

[0045] A buffer pad 19 extends from the center of the rubber main spring 14. The buffer pad 19 is located on the top surface of the disc component 17. Multiple raised ridges 20 are regularly arranged on the top surface of the buffer pad 19, and these ridges are parallel to each other. There is a gap between the buffer pad 19 and the inner wall of the compressor connecting bracket 5. A groove 21 is formed on the surface of the buffer pad 19, perpendicular to the raised ridges 20. The design of the buffer pad 19 further enhances the buffering performance of the rubber main spring 14. The raised ridges 20 on the top surface of the buffer pad 19 effectively disperse vibration energy and reduce vibration transmission. The groove 21 increases the flexibility of the buffer pad 19, allowing it to better adapt to different vibration conditions when compressed, further improving the vibration isolation effect of the suspension system.

[0046] The diameter of the anti-collision pad 7 gradually decreases from top to bottom, and the inner wall surface of the anti-collision pad 7 is regularly arranged with raised ribs, which cover the entire inner wall surface of the anti-collision pad 7. The design of the anti-collision pad 7 with its diameter gradually decreasing from top to bottom allows the anti-collision pad 7 to better disperse stress when subjected to impact, reducing the damage of impact force to the main spring assembly 1. The raised rib design on the inner wall surface further enhances the structural strength and wear resistance of the anti-collision pad 7, extends the service life of the anti-collision pad 7, and also better protects the main spring assembly 1 from damage by external impacts.
