[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 In this embodiment of the utility model, a vehicle air conditioner with a noise reduction and vibration damping structure includes a compressor 1. An upper noise reduction and vibration damping device 2 and a lower noise reduction and vibration damping device 3 are respectively installed on the top and bottom of the compressor 1. An upper fixing frame 4 and a lower fixing frame 5 are respectively fixedly connected to the other end of the upper noise reduction and vibration damping device 2 and the lower noise reduction and vibration damping device 3.
[0031] The upper noise reduction and vibration damping device 2 and the lower noise reduction and vibration damping device 3 are composed of the same structure; the upper fixing frame 4 and the lower fixing frame 5 are composed of the same structure.
[0032] The noise reduction and vibration damping device 2 includes two symmetrically arranged second fixed seats 21. The upper end of the second fixed seat 21 is provided with a rubber pad 22, and the upper end of the rubber pad 22 is provided with a lower spring 23. The lower spring 23 is slidably connected with a lower sound-absorbing cotton 24, which is also spirally arranged.
[0033] The upper end of the lower spring 23 is connected to the connecting plate 26, the connecting plate 26 is threadedly connected to the limiting bolt 25, and the upper end of the connecting plate 26 is connected to the washer 27 and the pressure reducing pad 28, with the washer 27 and the pressure reducing pad 28 connected at the middle position.
[0034] The upper end of the pressure-reducing pad 28 is connected to the connecting plate 29, the upper end of the connecting plate 29 is connected to the upper spring 213, the upper sound-absorbing cotton sleeve 214 is slidably connected to the upper spring 213, and the upper end of the upper spring 213 is connected to the outer shell 212.
[0035] By adopting the above technical solution, the setting of the lower sound-absorbing cotton 24 and the upper sound-absorbing cotton sleeve 214, together with the sound insulation effect of the rubber pad 22, constructs a comprehensive noise reduction system, which can significantly reduce the noise generated when the compressor vibrates, create a quiet and comfortable environment in the car, improve the riding experience of drivers and passengers, reduce noise interference to drivers and passengers, and help relieve fatigue, especially during long-distance driving.
[0036] In this embodiment, the limiting bolt 25 passes through the washer 27, the pressure reducing pad 28 and the connecting plate 29 and is threadedly connected to the fixing adjusting bolt 210. The upper end of the fixing adjusting bolt 210 is connected to the shock-absorbing plate 41, and the upper end of the shock-absorbing plate 41 is connected to the mounting plate 42. The upper end of the mounting plate 42 is symmetrically provided with connecting bolts 43. The shock-absorbing plate 41 and the mounting plate 42 are fixed to the fixing adjusting bolt 210 by the connecting bolts 43.
[0037] By adopting the above technical solution, the stiffness and height of the shock absorption device can be easily adjusted by adjusting the threaded connection between the limit bolt 25 and the fixed adjustment bolt 210. During the use of the vehicle air conditioner, when the compressor 1 vibrates to different degrees due to changes in operating conditions, it can be adjusted in time to ensure that the shock absorption and noise reduction effect is always in the best state. In addition, this structural design also facilitates the inspection, maintenance and replacement of various components in the later stage, reducing maintenance costs and difficulties.
[0038] In this embodiment, the compressor 1 includes a compressor body 11. The upper and lower ends of the compressor body 11 are symmetrically provided with fixing plates 12. A first fixing seat 13 is installed on the fixing plate 12. A fixing post 14 is provided at each of the four corners of the first fixing seat 13. The other end of the fixing post 14 is fixedly connected to the buffer seat 15. A second fixing seat 21 is symmetrically installed on the upper end of the buffer seat 15.
[0039] By adopting the above technical solution, the combination design of double-layer springs and buffer seat 15 forms a highly efficient shock absorption system during use. This system can effectively absorb and disperse the strong vibrations generated when the compressor 1 is running, preventing vibrations from damaging other components of the vehicle air conditioner and the vehicle body. This extends the service life of the vehicle air conditioner and related vehicle components, and reduces the frequency of failures caused by vibrations.
[0040] The working principle of this utility model is as follows: On the second fixed seat 21, the lower spring 23 plays a key role. The elastic deformation characteristics of the lower spring 23 can convert vibration energy into its own elastic potential energy, thereby reducing the transmission of vibration. As the vibration continues to be transmitted, the connecting plate 26 transmits the vibration to the pad 27 and the pressure relief pad 28 in sequence. The pressure relief pad 28 further buffers the vibration and reduces the impact of the vibration. Subsequently, the connecting plate 29 transmits the vibration to the upper spring 213. The upper spring 213 absorbs the remaining vibration energy again through elastic deformation. After the buffering of multiple layers of springs, the impact of vibration on surrounding components is greatly reduced.
[0041] When in use, the combination of double-layer springs and buffer seat 15 forms a highly efficient shock absorption system, which can effectively absorb and disperse the strong vibrations generated when the compressor 1 is running, avoid damage to other parts of the vehicle air conditioner and the vehicle body caused by vibration, extend the service life of the vehicle air conditioner and related vehicle components, and reduce the frequency of failures caused by vibration.
[0042] During the vibration transmission process, the lower sound-absorbing cotton 24 is spirally connected to the lower spring 23. Its spiral structure increases the surface area and can effectively absorb the noise generated when the compressor is working. As the noise propagates upward, the upper sound-absorbing cotton sleeve 214 is slidably connected to the upper spring 213 to further absorb the remaining noise. At the same time, the rubber pad 22 can also block some noise and reduce its propagation to the surrounding environment.
[0043] The lower sound-absorbing cotton 24 and the upper sound-absorbing cotton sleeve 214, together with the sound insulation effect of the rubber pad 22, form a comprehensive noise reduction system, which can significantly reduce the noise generated when the compressor vibrates, create a quiet and comfortable environment in the car, improve the riding experience of the driver and passengers, reduce the interference of noise on the driver and passengers, and help relieve fatigue, especially during long-distance driving.
[0044] By adjusting the threaded connection between the limit bolt 25 and the fixed adjustment bolt 210, the stiffness and height of the shock absorption device can be easily adjusted. During the use of the vehicle air conditioner, when the compressor 1 vibrates to different degrees due to changes in operating conditions, it can be adjusted in time to ensure that the shock absorption and noise reduction effect is always in the best state. In addition, this structural design also facilitates the inspection, maintenance and replacement of various components in the later stage, reducing maintenance costs and difficulties.
