[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] This application provides a vibration damping device to solve the problem of compressors having difficulty restoring their balance. The following description will be provided in conjunction with the accompanying drawings.

[0030] In the embodiments of this application, such as Figure 1 As shown, the vibration damping device includes a connector 1, a first damping member 2, and a second damping member 3 connected sequentially from top to bottom. The connector 1 is used for the compressor 4 to pass through and connect to the outer surface of the compressor 4, so that at least a portion of the compressor 4 is located between the connector 1, the first damping member 2, and the second damping member 3.

[0031] It should be noted that the first vibration damper 2 and the second vibration damper 3 refer to structures that can reduce the vibration and impact of the compressor 4. The first vibration damper 2 and the second vibration damper 3 can adopt the same or different structures. For example, the first vibration damper 2 and the second vibration damper 3 can be independently selected from one or more of rubber feet, vibration damping springs, air-filled shock absorbers, and hydraulic shock absorbers. The vibration damping directions of the first vibration damper 2 and the second vibration damper 3 can be the same or different. For example, the first vibration damper 2 is used to reduce the horizontal vibration of the compressor 4, and the second vibration damper 3 is used to reduce the vibration of the compressor 4 in the direction of gravity; or, both the first vibration damper 2 and the second vibration damper 3 are used to reduce the vibration of the compressor 4 in the direction of gravity. The vibration damping device here can be applied to a vertical compressor 4 or a horizontal compressor 4, with preference given to vertical compressor 4.

[0032] Understandably, the first damping element 2 and the second damping element 3 can increase the damping force against the vibration of the compressor 4, or increase the damping force in different directions, thereby improving the damping effect. Furthermore, by placing at least a portion of the compressor 4 within the damping device, specifically between the connecting element 1, the first damping element 2, and the second damping element 3, the swaying amplitude of the compressor 4 during damping is reduced, shortening the damping process. Especially when the damping device is applied to a vertical compressor 4, compared to related technologies, it can significantly reduce the swaying of the upper part of the compressor 4. Overall, it allows the compressor 4 to return to a balanced state more quickly. In addition, it can extend the lifespan of the connection between the compressor 4 and the connecting element 1, and reduce the size of the damping device.

[0033] In some embodiments, such asFigure 2 As shown, the second damping member 3 includes a damping plate 31 and a plurality of damping foot pads 32, the damping plate 31 is connected between the plurality of damping foot pads 32 and the first damping member 2; the first damping member 2 and the damping foot pads 32 are staggered in the direction from top to bottom.

[0034] It should be noted that the damping plate 31 and the damping foot pad 32 refer to the structure that can reduce the vibration and impact of the compressor 4. The first damping member 2 and the damping foot pad 32 are staggered in the direction from top to bottom, which means that when observing the damping device from top to bottom, the first damping member 2 and the damping foot pad 32 can be observed at the same time. The direction from top to bottom refers to the direction of gravity.

[0035] It can be understood that, on the one hand, the connection position of the first damping member 2 and the plurality of damping foot pads 32 on the damping plate 31 can be avoided, and on the other hand, when the first damping member 2 and the damping foot pad 32 are both used to reduce the vibration in the direction of gravity of the compressor 4, the staggered first damping member 2 and the damping foot pad 32 can slow down the force in the direction of gravity but in different positions in the horizontal direction, which has better damping effect.

[0036] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the damping plate 31 includes a mounting portion 311 and a plurality of damping portions 312, the mounting portion 311 is connected with the first damping member 2, and the plurality of damping portions 312 are connected with the plurality of damping foot pads 32 one by one.

[0037] It should be noted that the damping portion 312 refers to the structure that can reduce the vibration and impact of the compressor 4. The damping portion 312 can slow down the vibration in the direction of gravity or the horizontal direction. For example, the first damping member 2 and the damping portion 312 are both used to reduce the vibration in the direction of gravity of the compressor 4, the damping portion 312 can slow down the impact force from the compressor 4 and the force acting on the damping portion 312 during the damping process of the first damping member 2, thereby reducing the impact force that the damping foot pad 32 needs to reduce, strengthening the damping effect, and further shortening the damping process. The plurality of damping portions 312 are connected with the plurality of damping foot pads 32 one by one, which means that the number of damping portions 312 and damping foot pads 32 is the same. Exemplarily, the damping portion 312 can adopt common structural devices such as springs, elastic sheets, shock-absorbing rubbers, etc.

[0038] In some embodiments, as shown in Figure 2 As shown, the edge of the damping plate 31 is bent to form the damping portion 312, at least part of the damping portion 312 forms an included angle with the mounting portion 311, and at least part of the damping portion 312 is arranged in relative spacing with the mounting portion 311.

[0039] It should be noted that the angle between at least part of the damping part 312 and the mounting part 311 means that the angle between at least part of the damping part 312 and the mounting part 311 is not equal to 0 degree or 180 degree. In this way, when the mounting part 311 is subjected to force from the structure above it, the damping part 312 can play a damping role. Exemplarily, the damping part 312 and at least part of the mounting part 311 connected thereto are approximately U-shaped structure; the damping part 312 can be bent at different positions in the direction away from the mounting part 311 to form a wave structure.

[0040] In some embodiments, as shown in Figure 3 and Figure 4 , the outer periphery of the damping foot pad 32 is inwardly recessed to form a clamping groove 321, a first foot pad part 322 located on the upper side of the clamping groove 321, and a second foot pad part 323 located on the lower side of the clamping groove 321, the damping part 312 is sleeved on the damping foot pad 32 and embedded in the clamping groove 321, and the first foot pad part 322 is located between the mounting part 311 and the damping part 312.

[0041] It should be noted that the damping part 312 is sleeved on the damping foot pad 32 and embedded in the clamping groove 321 means that the damping part 312 is provided with a hole for the damping foot pad 32 to pass through, and when the damping foot pad 32 passes through the hole of the damping part 312, the damping part 312 can be installed in the clamping groove 321, and at this time the first foot pad part 322 located between the mounting part 311 and the damping part 312 can reduce the impact force between the mounting part 311 and the damping part 312. At the same time, by installing the damping part 312 in the clamping groove 321, the damping foot pad 32 can reduce the vibration of the damping part 312 in the horizontal direction.

[0042] In some embodiments, the damping foot pad 32 is provided with a fastener for fastening connection with the bottom plate, at least part of the fastener penetrates the bottom plate and the damping foot pad 32 and is fastened on the first foot pad part 322. Here, the bottom plate refers to the structure on the air conditioner outdoor unit for fixing the damping foot pad 32. The damping foot pad 32 is hollow, on the one hand to facilitate the fastener to pass through, and on the other hand to facilitate the first foot pad part 322 to deform when the damping part 312 passes through the first foot pad part 322.

[0043] In some embodiments, as shown in Figure 2 , the side of the second foot pad part 323 facing the first foot pad part 322 is supported on the lower side of the damping part 312. In this way, it is beneficial to improve the stability of the damping plate 31.

[0044] In some embodiments, as shown in Figure 3 , the damping plate 31 is provided with an avoiding hole 313 for avoiding the movement of the compressor 4 in the damping direction of the first damping part 2.

[0045] It should be noted that, due to the limited space where the compressor 4 is located, and at the same time, the maximum compression stroke during the damping process of the first damping member 2 needs to be considered, therefore, the avoiding hole 313 can increase the space where the compressor 4 can move in the direction of gravity in the limited space, and the damping effect of the first damping member 2 is not sacrificed.

[0046] In some embodiments, as shown in Figure 1 The connecting member 1 includes a connecting seat 11 and a fixed baffle 12, the connecting seat 11 is used for sleeving on the compressor 4 and connecting with the upper end of the first damping member 2, and the fixed baffle 12 is provided with a plurality of fixed baffles 12 circumferentially along the connecting seat 11 and is used for connecting the compressor 4.

[0047] It can be understood that the connecting seat 11 and the fixed baffle 12 can separate the connection positions of the compressor 4 and the first damping member 2 on the connecting member 1, so that the stress of the connecting member 1 is not too concentrated.

[0048] In some embodiments, as shown in Figure 2 The fixed baffle 12 is fixedly connected to the inner side of the connecting seat 11 and protrudes axially along the connecting seat 11. It can be understood that the fixed baffle 12 can provide more connection positions for the compressor 4 in the direction of gravity; the connecting seat 11 facilitates providing connection positions for the first damping member 2 in the horizontal direction, so that the first damping member 2 can ensure the appropriate distance with the compressor 4, and also facilitates that there are enough positions on the connecting seat 11 for the first damping member 2 to connect, improving the installation stability of the first damping member 2; providing positions for the first damping member 2 and the compressor 4 to adapt to their respective installation characteristics.

[0049] In some embodiments, as shown in Figure 2 The first damping member 2 includes a plurality of dampers 21 arranged circumferentially along the connecting seat 11, and the dampers 21, the second damping member 3 and the fixed baffle 12 are arranged alternately in the direction from top to bottom.

[0050] It should be noted that the damper 21 refers to a device that provides movement resistance and consumes movement energy. "The dampers 21, the second damping member 3 and the fixed baffle 12 are arranged alternately in the direction from top to bottom" means that when observing the damping device from top to bottom, the dampers 21, the second damping member 3 and the fixed baffle 12 can be observed at the same time. In this way, the stress generated when the damping device resists the vibration of the compressor 4 can be dispersed, and the service life of the connection position between the compressor 4 and the fixed baffle 12 and the connection position between the damper 21 and the second damping member 3 can be prolonged. Specifically, the damper 21 can adopt a hydraulic damper 21.

[0051] In some embodiments, as shown in Figure 2 and Figure 3As shown, the connecting seat 11 is provided with a plurality of upward protruding first connecting portions 111, the damping member is provided with a plurality of downward protruding second connecting portions 33, the upper and lower ends of the damper 21 are connected with the first connecting portions 111 and the second connecting portions 33 respectively, and the plurality of dampers 21, the plurality of first connecting portions 111 and the plurality of second connecting portions 33 are one-to-one corresponding.

[0052] It can be understood that a damper 21 with a longer length can be arranged between the upward protruding first connecting portion 111 and the downward protruding second connecting portion 33 to improve the damping effect.

[0053] Specifically, the upper end and the lower end of the damper 21 are both provided with a stepped surface. The upper end of the damper 21 is provided with a stepped surface for lap joint with the first connecting portion 111, and the upper end of the damper 21 is screwed with a nut after passing through the first connecting portion 111, the nut and the stepped surface of the upper end of the damper 21 jointly clamp the first connecting portion 111, and the damper 21 and the first connecting portion 111 are gap-fitted to provide a rotating space for the connecting seat 11.

[0054] The lower end of the damper 21 is screwed with a nut after passing through the second connecting portion 33, and the nut and the stepped surface of the lower end of the damper 21 jointly clamp the second connecting portion 33.

[0055] In some embodiments, as shown, Figure 3 As shown, the dampers 21 and the damping foot pads 32 are both arranged at three equal intervals in the circumferential direction of the compressor 4. Correspondingly, the first connecting portions 111, the second connecting portions 33 and the damping portions 312 are all arranged at three.

[0056] The embodiment of the present application also provides an air conditioner outdoor unit, which comprises the above damping device and a compressor 4, and the specific structure of the damping device is referred to the above embodiments. Since the air conditioner outdoor unit adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The compressor 4 is located between the connecting member 1, the first damping member 2 and the second damping member 3, and the compressor 4 is connected to the connecting member 1.

[0057] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments. In the description of the present application, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
