[0002] The compressor is the core component of the air conditioning system and also the main noise source of the air conditioning system. There are mainly three forms of compressor noise: (1) the noise generated by the operation of the compressor itself; (2) the noise generated by the vibration of the compressor transmitted to the pipeline, chassis and shell; (3) the noise generated by the refrigerant flow. In order to reduce the noise generated by the vibration of the compressor itself, it is necessary to carry out vibration damping design for the compressor, absorb the vibration generated by the compressor, and reduce the transmission of vibration.

[0003] At present, in the related art, a plurality of primary foot pads and secondary foot pads are provided on the support base, and the two-level foot pads are respectively connected to the chassis and the compressor to achieve secondary vibration damping. Although this device can play a role in secondary vibration damping, due to the setting of a plurality of foot pads and the two-layer structure of the foot pads, not only the number of parts is large and the working hours are consumed, but also after the unit is assembled, the two-level foot pads increase the center of gravity of the compressor, which is extremely easy to cause the center of gravity of the compressor to be unstable and tilt to one side, and the compressor base feet are in hard contact with the bolts, thereby generating noise and transmission.

[0004] Therefore, the existing technology needs to be further developed. Content of the Utility Model

[0007] Further, the vibration damping plate is made of rubber material.

[0008] Further, a first through hole is arranged on the transfer plate, a second through hole is arranged on the vibration damping plate, and the secondary vibration damping device of the compressor further includes a fastener, and the fastener sequentially passes through the first through hole and the second through hole to connect the transfer plate assembly and the chassis.

[0009] Further, the first through hole is located at the center of the transfer plate, and the second through hole is located at the center of the vibration damping plate.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0026] According to an embodiment of the present utility model, a secondary shock-absorbing device for a compressor is provided. Please refer to Figures 1 to 5 , including: a shock-absorbing foot pad 1, the shock-absorbing foot pad 1 is arranged on the base foot 21 of the compressor 2, and the shock-absorbing foot pad 1 is used for shock-absorbing the compressor 2; an adapter plate assembly 3, the adapter plate assembly 3 includes an adapter plate 31 and a shock-absorbing plate 32, the shock-absorbing plate 32 is attached to the adapter plate 31, the shock-absorbing foot pad 1 is arranged on the side of the adapter plate 31 away from the shock-absorbing plate 32, the shock-absorbing plate 32 is used for shock-absorbing the compressor 2, the shock-absorbing plate 32 is connected to the chassis 4 below the compressor 2, and the base foot 21 is fixed on the adapter plate 31. The base foot 21 of the compressor 2 is fixed on the adapter plate 31, and a shock-absorbing foot pad 1 is arranged on the base foot 21 to reduce and buffer the vibration generated by the compressor 2. A shock-absorbing plate 32 is attached below the adapter plate 31, the shock-absorbing plate 32 is used for shock-absorbing the compressor 2, and the other side of the shock-absorbing plate 32 is attached to the chassis 4. The vibration of the compressor 2 is first shock-absorbed by the shock-absorbing foot pad 1 at the first level, and then shock-absorbed by the shock-absorbing plate 32 of the adapter plate assembly 3 at the second level. Through this secondary shock-absorbing structure, the vibration generated by the compressor 2 can be effectively absorbed, and at the same time, the vibration transmitted from the compressor 2 to the chassis 4 and the housing can be reduced, greatly reducing the noise generated by the compressor 2. Compared with the prior art, setting the shock-absorbing plate 32 to replace multiple secondary shock-absorbing foot pads not only reduces the number of parts and improves the assembly efficiency; after the unit is assembled, the distance from the compressor 2 to the chassis 4 is greatly shortened, the center of gravity of the compressor is reduced, and the hard contact between the compressor and the chassis during shaking is prevented, avoiding the generation of greater noise. The secondary shock-absorbing device of the compressor in this embodiment solves the technical problem of large vibration and high noise during the operation of the compressor in the related art.

[0027] In the secondary vibration damping device of the compressor in this embodiment, the vibration damping plate 32 is made of rubber material. The whole rubber pad is attached between the adapter plate 31 and the chassis 4 to reduce or offset the vibration generated by the upper compressor 2, greatly reducing the vibration transmitted from the compressor 2 to the chassis 4 and the housing, and reducing the noise.

[0028] Refer to Figure 2 and Figure 3 , in the secondary vibration damping device of the compressor in this embodiment, the adapter plate 31 is provided with a first through hole 311, and the vibration damping plate 32 is provided with a second through hole 321. The secondary vibration damping device of the compressor further includes a fastener, and the fastener sequentially passes through the first through hole 311 and the second through hole 321 to connect the adapter plate assembly 3 to the chassis 4. The fastener passes through the first through hole 311 on the adapter plate 31, then passes through the second through hole 321 on the rubber pad and enters the chassis 4 to connect the adapter plate assembly 3 to the chassis 4.

[0029] Refer to Figure 2 and Figure 3 , in the secondary vibration damping device of the compressor in this embodiment, the first through hole 311 is located at the center of the adapter plate 31, and the second through hole 321 is located at the center of the vibration damping plate 32. The adapter plate 31 covers the rubber pad, and the rubber pad is laid on the chassis 4. The three of them have formed a stable connection. Coupled with the setting of the fastener, the firmness of the connection of the three is improved. The first through hole 311 and the second through hole 321 are respectively at the centers of the adapter plate 31 and the rubber pad. Such a setting can reduce the number of parts and assembly steps while strengthening the connection of the three. In this embodiment, the adapter plate 31 and the rubber pad are hexagonal. In actual use, the adapter plate 31 and the rubber pad are not limited to hexagons and can be circular, square or other irregular shapes.

[0030] Refer to Figure 3 , in the secondary vibration damping device of the compressor in this embodiment, the aperture of the first through hole 311 is larger than the aperture of the second through hole 321, so that there is a gap 33 between the adapter plate 31 and the vibration damping plate 32, and the fastener is arranged in the gap 33. It can be seen from the section of this structure that the gap 33 formed by the apertures of the adapter plate 31 and the vibration damping plate 32 is in a trapezoidal structure with a wider upper part and a narrower lower part. This structure plays a role of making way, provides an installation space for the installation of the fastener, and prevents the bottom of the compressor 2 from contacting the fastener.

[0031] Refer to Figure 4 , in the secondary vibration damping device of the compressor in this embodiment, a positioning groove 34 is provided on the side of the vibration damping plate 32 away from the adapter plate 31, and the positioning groove 34 coincides with the protrusion of the chassis 4. The bottom of the rubber pad is provided with a positioning groove 34 that coincides with the protrusion of the chassis 4, which plays a role of limiting the position and prevents the adapter plate assembly 3 from rotating and deviating from the installation position. In this embodiment, the positioning groove 34 is rectangular. In actual use, the structure of the positioning groove 34 is set according to the protrusion of the chassis 4.

[0032] Refer to Figure 3 Figure 3 , for the secondary vibration damping device of the compressor in this embodiment, the edge of the adapter plate 31 is folded inward to form a folded edge 312, and an installation groove 322 is provided around the vibration damping plate 32. The folded edge 312 is embedded in the installation groove 322 to connect the adapter plate 31 and the vibration damping plate 32. The outer edge of the adapter plate 31 is folded toward the center to form a folded edge 312, and the folded edge 312 is embedded in the installation groove 322 around the vibration damping plate 32, making the connection between the adapter plate 31 and the rubber pad more firm.

[0033] Refer to Figure 5 Figure 5 , for the secondary vibration damping device of the compressor in this embodiment, a positioning bolt 35 is provided on the adapter plate 31. The vibration damping foot pad 1 is sleeved on the positioning bolt 35, and the positioning bolt 35 is connected to the base foot 21. The base foot 21 and the adapter plate 31 are connected through the positioning bolt 35. One end of the vibration damping foot pad 1 is connected to the base foot 21, and the other end of the vibration damping foot pad 1 is connected to the adapter plate 31. One end of the positioning bolt 35 is connected to the base foot 21, and the other end is fixed on the adapter plate 31; the vibration damping foot pad 1 is sleeved on the positioning bolt 35, one end is connected to the base foot 21, and the other end is fixed on the adapter plate 31, which is used to weaken or offset the vibration generated by the compressor 2 and reduce the vibration transmitted to the chassis 4.

[0034] Refer to Figure 1 Figure 1 , for the secondary vibration damping device of the compressor in this embodiment, there are multiple base feet 21, and the base feet 21 are arranged at intervals around the compressor 2. There are multiple positioning bolts 35 and vibration damping foot pads 1, and each positioning bolt 35, each vibration damping foot pad 1 and each base foot 21 are arranged in one-to-one correspondence. The vibration damping foot pads 1 are arranged around the circumference of the compressor 2 to damp the vibration of the compressor 2 from all directions.

[0035] An air conditioner includes the secondary vibration damping device of the compressor as described above. When the air conditioning system operates, the vibration of the compressor is first subjected to primary vibration damping by the vibration damping foot pads 1, and then subjected to secondary vibration damping by the rubber pads of the adapter plate assembly 3, effectively absorbing the vibration generated by the compressor, reducing the vibration transmitted from the compressor to the chassis 4 and the outer casing, and reducing the noise generated by the compressor. Since only fasteners are provided at the center of the adapter plate 31 and the rubber pad, hard contact between the compressor base foot 21 and the fasteners is avoided, and noise transmission is avoided; the number of parts is also relatively small, and the assembly efficiency is high. The rubber pad is provided with an inward concave installation groove 322 around its periphery, which can be clamped and fixed in cooperation with the folded edge 312 on the adapter plate 31. The center of the adapter plate assembly 3 is provided with bolt holes for fixing in cooperation with the chassis 4. The bottom of the rubber pad is provided with two rectangular positioning grooves 34, which fit with the protrusions on the chassis 4 to prevent the adapter plate assembly 3 from rotating. Through the secondary vibration damping device of the compressor, the vibration of the compressor can be effectively reduced, the vibration of the chassis and the outer casing can be reduced, thereby reducing the noise of the entire air conditioning system and improving the product competitiveness.
