Description

Technical Field

[0001] This utility model relates to the field of buffer and vibration reduction technology, and in particular to a compressor vibration reduction component and a motorhome air conditioner. Background Technology

[0002] Vehicle air conditioning systems are air conditioning devices installed in vehicles. Vibrations during vehicle operation and the air conditioning system itself can affect the stability and lifespan of the equipment. Vibration-damping installation technology helps to buffer and reduce vibrations, improving the stability and lifespan of the equipment. In existing technologies, vibration damping devices often use a single structure for buffering, such as rubber pads or springs. Their parameters are fixed and cannot be adjusted according to actual operating conditions, making it difficult to adapt to vibration damping requirements under different load conditions. For example, a single damping mode cannot perform well simultaneously under multiple vibration conditions, such as vibrations caused by vehicle operation, vibrations caused by the air conditioning unit itself, or vibrations caused by both.

[0003] Therefore, it is necessary to propose a technical solution to overcome the shortcomings of existing technologies. Utility Model Content

Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 As shown, this utility model discloses a compressor vibration damping component 30 and a motorhome air conditioner equipped with the component. In this embodiment, the compressor vibration damping component 30 is installed between the compressor 10 and the compressor mounting bracket 20 of the vehicle air conditioner to dampen the compressor 10.

[0025] The compressor vibration damping assembly 30 includes a composite support base 1, a flexible compression member 2, and a pressure regulating connector 3. The composite support base 1 includes a rigid connecting and fixing part 11 and a flexible support pad part 12, with the support pad part 12 positioned above the connecting and fixing part 11. The flexible compression member 2 is adapted to be assembled above the support pad part 12 of the composite support base 1. A hollow hole is provided in the middle of both the flexible compression member 2 and the support pad part 12. The pressure regulating connector 3 includes a pressure regulating screw 31, which passes through the hollow hole and its lower end is threadedly connected and fixed to the connecting and fixing part 11 or the compressor mounting bracket 20. The flexible compression member 2 and the support pad part 12 are elastically compressed and deformed between the connecting and fixing part 11 and the pressure regulating screw 31.

[0026] The compressor vibration damping assembly 30 provided by this utility model includes a composite support base 1, a flexible compression component 2, and a pressure regulating connector 3. The composite support base 1 includes a rigid connecting and fixing part 11 and a flexible support pad part 12. The support pad part 12 is located above the connecting and fixing part 11. The flexible compression component 2 is adapted to be assembled above the support pad part 12 of the composite support base 1. The flexible compression component 2 and the support pad part 12 are elastically compressed and deformed between the connecting and fixing part 11 and the pressure regulating screw 31. Through such a multi-layer elastic buffer and adjustable preload design, multi-level attenuation of compressor operating vibration is achieved, solving the defect of existing vibration damping devices that cannot dynamically adapt to multi-condition vibration, significantly improving the vibration damping effect, and improving the operating stability and service life of the vehicle air conditioning compressor 10.

[0027] Please see Figure 5 As shown, the composite support base 1 serves as a basic support unit, comprising a rigid connecting and fixing part 11 and a flexible support pad part 12. In this embodiment, the support pad part 12 is a rubber body, and the connecting and fixing part 11 is a metal part, with the support pad part 12 and the connecting and fixing part 11 integrally formed. Specifically, the connecting and fixing part 11 is generally a plate-shaped body made of metal, with outwardly protruding mounting parts at both ends. In this embodiment, the connecting and fixing part 11 is a roughly rugby ball-shaped sheet, with the mounting parts protruding beyond the support pad 32, and mounting holes 110 are provided on the mounting parts. By passing connecting screws 4 through the mounting holes 110 and the corresponding holes of the compressor mounting bracket 20, and locking nuts at their lower ends, the entire composite support base 1 is fixed to the compressor mounting bracket 20. In this embodiment, the mounting holes 110 are oblong holes, so that alignment and connection can still be achieved even if there are certain machining errors in the corresponding round holes on the compressor mounting bracket 30.

[0028] In this embodiment, the support pad 12 is made of rubber and is integrally connected to the connecting fixing part 11 through a vulcanization molding process to ensure reliable connection. In this embodiment, the support pad 12 has an expansion head 121 at the upper end and a constriction neck 122 connecting the expansion head 121 and the connecting fixing part 11. That is, the upper end of the support pad 12 forms the expansion head 121, and the lower end is transitionally connected to the connecting fixing part 11 through the constriction neck 122. This variable cross-section structure allows the support pad 12 to disperse stress concentration by deforming towards the space around the constriction neck 122 when under pressure, while the expansion head 121 provides a larger contact area to enhance stability.

[0029] Please see Figures 3 to 5 As shown, in this embodiment, the flexible compression member 2 is generally wider at the bottom and narrower at the top. Several annular grooves 21 are formed on the peripheral wall of the flexible compression member 2 to provide compression deformation space. Specifically, the flexible compression member 2 has a frustum-shaped structure that is wider at the bottom and narrower at the top, providing stable support and preventing tilting. Multiple annular grooves 21 are formed on the peripheral wall of the flexible compression member 2, distributed in the vertical direction. These annular grooves 21 form a deformation buffer space when compressed, allowing the flexible compression member 2 to undergo elastic compression deformation along the axial direction. In this embodiment, the flexible compression member 2 is made of a different elastomer material than the support pad 12. The two materials have different elastic moduli. The rubber body of the support pad 12 focuses on absorbing low-frequency, large-amplitude vibrations, while the flexible compression member 2 attenuates high-frequency, small-amplitude vibrations. This difference in elasticity allows for graded filtering of broadband vibrations to accommodate different types of vibration.

[0030] In this embodiment, the pressure regulating connector 3 includes a pressure regulating screw 31, a washer 32, and a fixed bushing 33. A threaded stud cylinder is provided in the middle of the connecting and fixing part 11 of the composite support base 1. The lower end of the pressure regulating screw 31 is threaded into the stud cylinder. The compression amount of the flexible compression member 2 and the support pad 12 can be adjusted by adjusting the thread engagement depth. The fixed bushing 33 is inserted into the hollow holes of the support pad 12 and the flexible compression member 2. The fixed bushing 33 can be used to guide the insertion of the pressure regulating screw 31 and its connection with the stud cylinder. Simultaneously, the fixed bushing 33 is used to allow the flexible compression member 2 and the support pad 12 to deform under pressure. The pressure regulating screw 31 passes through the fixed bushing 33, and sequentially passes through the washer 32, the flexible compression member 2, and the support pad 12 before connecting to the stud cylinder.

[0031] During connection, the support plate 101 of the compressor 10 is supported on the flexible compression member 2, the gasket 32 ​​covers the support plate 101 of the compressor 10, and the support hole 102 on the support plate 101 is aligned with the hollow hole. The pressure regulating screw 31 passes through the gasket 32, the support plate 101 of the compressor 10, the flexible compression member 2, and the support pad 12 in sequence and connects to the connection fixing part 11. When the pressure regulating screw 31 is tightened, its rod applies downward pressure to the fixed bushing 33, thereby compressing and deforming the flexible compression member 2 and the support pad 12, generating a preload force matching the weight of the compressor. At the same time, the natural frequency of the system is adjusted by the elastic deformation to avoid resonance with the operating frequency of the compressor. In this embodiment, the compressor vibration damping assembly 30 is configured in three sets to connect the compressor 10 to the compressor mounting bracket 20 at three points. In other embodiments, the compressor vibration damping assembly 30 may also be configured in two sets, four sets, or other quantities.

[0032] The working process of one embodiment of the compressor vibration damping component 30 provided by this utility model is as follows: When the compressor 10 is running, the vibration generated is transmitted to the support plate 101. First, the flexible compression component 2 absorbs the high-frequency vibration energy through the deformation of the annular groove 21. The remaining vibration that is not completely attenuated continues to be transmitted to the support pad 12, where the internal friction characteristics of the rubber body are used to further dissipate the low-frequency vibration. By adjusting the compression amount by the pressure regulating screw 31, the stiffness combination of the two elastic layers can be changed, so that the system can maintain the best vibration damping effect under different loads or vibration frequencies. For example, when the RV air conditioner is in a high-load operating state, the screwing depth of the pressure regulating screw 31 can be appropriately increased to improve the preload and stiffness of the elastic system and avoid excessive static deformation; while under low load or vibration frequency changes, the compression amount can be reduced to enhance the low-frequency vibration filtering capability.

[0033] This utility model also provides a motorhome air conditioner. The motorhome air conditioner includes a compressor 10, an evaporator (not shown), a condenser (not shown), and connecting pipes (not shown). The lower end of the compressor 10 is fixed to the compressor mounting bracket 20 using a compressor vibration damping assembly 30 as described above to reduce the vibration of the compressor 10. In this embodiment, the lower end of the compressor 10 is symmetrically mounted on the compressor mounting bracket 20 using three sets of compressor vibration damping assemblies 30. Each vibration damping assembly 30 independently adjusts the compression, enabling the compressor 10 to maintain a stable operating posture under complex working conditions, significantly reducing the transmission of vibration to the vehicle body, and extending the service life of the air conditioning system and vehicle components.

[0034] As described above in the specific embodiments, the compressor vibration damping assembly 30 provided by this utility model includes a composite support base 1, a flexible compression member 2, and a pressure regulating connector 3. The composite support base 1 includes a rigid connecting and fixing part 11 and a flexible support pad part 12. The support pad part 12 is disposed above the connecting and fixing part 11. The flexible compression member 2 is adapted to be assembled above the support pad part 12 of the composite support base 1. The flexible compression member 2 and the support pad part 12 are elastically compressed and deformed between the connecting and fixing part 11 and the pressure regulating screw 31. Through such a multi-layer elastic buffer and adjustable preload design, multi-level attenuation of compressor operating vibration is achieved, solving the defect of existing vibration damping devices that cannot dynamically adapt to multi-condition vibration, significantly improving the vibration damping effect, and improving the operating stability and service life of the vehicle air conditioning compressor 10.

Those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or circumstances without departing from its scope.
