All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] In this application, the term "exemplary" is used to mean "used as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] This application provides a compressor vibration damping device that can be applied to air conditioners.

[0030] like Figures 1-8 As shown, the compressor vibration damping device provided in this application embodiment includes a base 100, a mounting bracket 200, and a first vibration damping component 300. The mounting bracket 200 is used to mount the compressor 800, and the first vibration damping component 300 is disposed on the base 100. The first vibration damping component 300 includes a plurality of first vibration damping members 310 supporting the mounting bracket 200. A limiting groove 101 is provided on the base 100, and the lower end of the first vibration damping member 310 is located in the limiting groove 101. The lower side of the first vibration damping member 310 abuts against the groove wall of the limiting groove 101.

[0031] The base 100 can be a separate component or can be an air conditioner chassis. Optionally, the mounting component can be a stamped metal part.

[0032] The compressor vibration damping device provided in this application embodiment, by setting a first vibration damping component 300 on the base 100, and the multiple first vibration damping elements 310 of the first vibration damping component 300 supporting the mounting bracket 200 for mounting the compressor 800, can dampen the compressor 800, thereby reducing the vibration transmitted from the compressor 800 to the air conditioning unit, and thus reducing the noise generated by the vibration when the compressor 800 is working; by setting a limiting groove 101 on the base 100, and making the lower end of the first vibration damping element 310 located in the limiting groove 101 and the lower end side of the first vibration damping element 310 abutting against the groove wall of the limiting groove 101, it can prevent the mounting bracket 200 from shaking in the horizontal direction and contacting the air conditioning sheet metal structure when the compressor 800 is working, thereby generating noise, further reducing the noise when the compressor 800 is working and improving the user experience.

[0033] Optionally, the surface of the base 100 is provided with an annular limiting rib 110, which, together with the surface of the base 100, forms a limiting groove 101. The lower side of the first damping member 310 abuts against the inner side of the limiting rib 110. Alternatively, in other embodiments, the limiting groove 101 can be directly recessed into the base 100.

[0034] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, the compressor vibration damping device also includes a bracket 400 and a second vibration damping component 500. The bracket 400 supports the compressor 800, and the second vibration damping component 500 is disposed on the side of the mounting bracket 200 facing away from the base 100. The second vibration damping component 500 includes multiple second vibration damping elements 510 supporting the bracket 400. By setting the second vibration damping component 500, the vibration damping effect can be enhanced. Specifically, the bracket 400 supports the bottom of the compressor 800, the second vibration damping component 500 is disposed between the bracket 400 and the mounting bracket 200, and the multiple second vibration damping elements 510 are used to reduce the vibration between the compressor 800 and the mounting bracket 200, achieving primary vibration damping; the first vibration damping component 300 is disposed between the mounting bracket 200 and the base 100, and the multiple first vibration damping elements 310 are used to reduce the vibration between the mounting bracket 200 and the base 100, achieving secondary vibration damping. This application reduces the vibration transmitted by the compressor 800 by combining primary and secondary vibration damping, greatly improving the vibration damping effect, thereby further reducing noise and improving the user experience.

[0035] It is understandable that the vibration generated by the compressor 800 during operation is directly transmitted to the sheet metal structure, which can lead to the following problems: long-term vibration can easily cause sheet metal parts to crack, screws to loosen, and even pipeline leaks. The compressor vibration reduction device of this application, by adopting a two-stage vibration reduction structure, can effectively reduce the noise generated by the vibration of the compressor 800 during operation, thereby improving the overall stability and service life of the machine.

[0036] Optionally, multiple second vibration damping components 510 are arranged circumferentially along the mounting bracket 200. A baffle is provided on the side of the mounting bracket 200 facing away from the base 100, with the baffle located on the side of the second vibration damping component 510 facing the center of the mounting bracket 200. By providing the baffle, the bracket 400 can be prevented from swaying horizontally during compressor 800 operation, thus preventing it from contacting the air conditioner sheet metal structure and generating noise. This further reduces the noise of the compressor 800 during operation and improves the user experience.

[0037] Optionally, the number of first damping elements 310 and second damping elements 510 is the same, and multiple first damping elements 310 and multiple second damping elements 510 are alternately distributed along the circumference of the mounting bracket 200. This arrangement can improve the vibration damping effect of the compressor damping device and make its operation more stable and reliable; at the same time, it can also ensure that the torque of the compressor 800 during operation is evenly transmitted to the mounting bracket 200, thereby avoiding uneven stress on the mounting bracket 200 during compressor 800 operation, which could lead to excessive noise. For example, as shown... Figure 5 and Figure 6 As shown, the first vibration damping assembly 300 includes three first vibration damping elements 310, and the second vibration damping assembly 500 includes three second vibration damping elements 510. The three first vibration damping elements 310 and the three second vibration damping elements 510 are alternately distributed along the circumference of the mounting frame 200.

[0038] In some embodiments of this application, the second vibration damping component 500 is configured to suppress low-frequency vibrations, and the first vibration damping component 300 is configured to suppress high-frequency vibrations. This configuration allows the compressor vibration damping device to adapt to different operating conditions and effectively suppress vibrations of different frequencies, thereby reducing the noise during compressor 800 operation. For example, the second vibration damping component 500 is configured to suppress low-frequency vibrations of 20Hz to 50Hz, and the first vibration damping component 300 is configured to suppress high-frequency vibrations of 50Hz to 200Hz.

[0039] Optionally, the first damping component 310 is a first damping pad, which has a first through hole 311. A damping spring 320 is disposed in the first through hole 311, and the axial direction of the damping spring 320 is parallel to the axial direction of the first through hole 311; the second damping component 510 is a second damping pad. This arrangement enables the second damping assembly 500 to suppress low-frequency vibrations and the first damping assembly 300 to suppress high-frequency vibrations.

[0040] The first vibration damping pad can be a rubber vibration damping pad, a silicone rubber vibration damping pad, or a silicone rubber vibration damping pad; that is, the first vibration damping pad can be a component made of rubber, silicone rubber, or silicone. The second vibration damping pad can also be a rubber vibration damping pad, a silicone rubber vibration damping pad, or a silicone rubber vibration damping pad; that is, the second vibration damping pad can be a component made of rubber, silicone rubber, or silicone.

[0041] For example, the second damping pad is a rubber damping pad with a Shore hardness of 40±5, which can suppress low-frequency vibrations of 20Hz~50Hz; the first damping pad is a rubber damping pad, and the damping spring 320 is a compression spring with a stiffness coefficient of 50N / mm, which can suppress high-frequency vibrations of 50Hz~200Hz.

[0042] Optional, such as Figure 8 As shown, the first damping pad has a conical structure, that is, the outer diameter of the first damping pad gradually increases from the upper end to the lower end, and the outer peripheral surface of the first damping pad is provided with at least one first annular groove 313. The first annular groove 313 provides deformation space for the first damping pad, making it easier for the first damping pad to generate elastic deformation, thereby more effectively suppressing the vibration generated when the compressor 800 is working, and achieving a good damping effect.

[0043] Optionally, the second damping pad has a conical structure, that is, the outer diameter of the second damping pad gradually increases from the upper end to the lower end, and the outer peripheral surface of the second damping pad is provided with at least one second annular groove. The second annular groove provides deformation space for the second damping pad, making it easier for the second damping pad to generate elastic deformation, thereby more effectively suppressing the vibration generated when the compressor 800 is working, and achieving a good vibration reduction effect.

[0044] In some embodiments of this application, such as Figures 1-7 As shown, the compressor vibration damping device also includes a first bolt 610 and a first nut 620. The first bolt 610 passes through the base 100, the first through hole 311, and the mounting bracket 200 in sequence before being threadedly connected to the first nut 620. The vibration damping spring 320 is sleeved on the first bolt 610. Through the cooperation of the first bolt 610 and the first nut 620, the base 100, the first vibration damping component 310, and the mounting bracket 200 can be connected.

[0045] Optionally, the second damping component 510 is also provided with a second through hole, and the compressor damping device also includes a second bolt 710 and a second nut 720. The second bolt 710 passes through the mounting bracket 200, the second damping pad, and the bracket 400 in sequence and is then threadedly connected to the first nut 620. Through the cooperation of the first bolt 610 and the first nut 620, the mounting bracket 200, the second damping component 510, and the bracket 400 can be connected.

[0046] Specifically, the base 100 has a first connecting hole, the mounting bracket 200 has a second connecting hole and a third connecting hole, and the first bolt 610 passes through the first connecting hole, the first through hole 311 of the first damping member 310 and the second connecting hole in sequence and is then threadedly connected to the first nut 620; the bracket 400 has a fourth connecting hole, and the second bolt 710 passes through the third connecting hole, the second through hole of the second damping member 510 and the fourth connecting hole in sequence and is then threadedly connected to the second nut 720.

[0047] For example, such as Figure 5 and Figure 6 As shown, the first vibration damping assembly 300 includes three first vibration damping elements 310, and the second vibration damping assembly 500 includes three second vibration damping elements 510. The three first vibration damping elements 310 and the three second vibration damping elements 510 are alternately distributed along the circumference of the mounting frame 200. A first connecting hole is provided on the base 100, three second connecting holes and three third connecting holes are provided on the mounting frame 200, and three fourth connecting holes are provided on the bracket 400. A first bolt 610, a first nut 620, a second bolt 710, and a second nut 72 are provided. The quantity of 0 is three. The four first bolts 610 pass through the three first connecting holes of the base 100, the first through holes 311 of the three first damping components 310 and the three second connecting holes of the mounting bracket 200 in sequence, and are then threadedly connected to the three first nuts 620 in a corresponding manner. The three second bolts 710 pass through the three third connecting holes of the mounting bracket 200, the second through holes of the three second damping components 510 and the three fourth connecting holes of the bracket 400 in sequence, and are then threadedly connected to the three second nuts 720 in a corresponding manner.

[0048] Alternatively, in other embodiments, a first slot 312 may be provided on the upper outer peripheral surface of the first damping member 310. The first damping member 310 is engaged with the mounting bracket 200 through the first slot 312, that is, the first damping member 310 is engaged with the mounting bracket 200 through the first slot 312, thereby realizing the connection between the first damping member 310 and the mounting bracket 200. Similarly, a second slot may be provided on the upper outer peripheral surface of the second damping member 510. The second damping member 510 is engaged with the bracket 400 through the second slot, that is, the second damping member 510 is engaged with the bracket 400 through the second slot, thereby realizing the connection between the second damping member 510 and the bracket 400.

[0049] This application also provides a window air conditioner, which includes a compressor 800 and a compressor vibration damping device. The specific structure of the compressor vibration damping device is the same as described in the above embodiments, and the compressor 800 is mounted on the mounting bracket 200 of the compressor vibration damping device. Since this window air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] It is understandable that when the compressor vibration damping device also includes a bracket 400 and a second vibration damping component 500, the bracket 400 is supported on the bottom of the compressor 800, the second vibration damping component 500 is disposed on the side of the mounting bracket 200 away from the base 100, and a plurality of second vibration damping elements 510 of the second vibration damping component 500 are supported on the bottom of the bracket 400.

[0051] The following is based on Figures 1-4 Taking the compressor vibration damping device and compressor 800 shown as examples, the installation process of the compressor vibration damping device and compressor 800 will be explained: First, connect multiple first damping components 310 and mounting bracket 200 to base 100 using first bolts 610 and first nuts 620, with a pre-tightening torque of 15 N·m. Adjust the pre-compression of damping spring 320 to ensure the natural frequency avoids the 25 Hz~35 Hz resonance zone. Then, connect multiple second damping components 510 and bracket 400 to mounting bracket 200 using second bolts 710 and second nuts 720. Finally, fix compressor 800 to bracket 400.
