For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] The present application provides a damping structure to solve the problem of low service life of the pipeline. The following will be described with reference to the drawings.

[0028] In the present application, as shown in the figure, Figure 1 The damping structure includes an elastic body 1, the elastic body 1 is used to be sleeved on the pipeline, the elastic body 1 is provided with a deformation groove 11, the extension direction of the deformation groove 11 and the deformation direction of the elastic body 1 form a first included angle, the degree of the first included angle is greater than 0 degrees and less than 180 degrees; when the pipeline vibrates and deforms the elastic body 1, the opposite two side walls of the deformation groove 11 contact and rub with each other.

[0029] It should be noted that the elastomer 1 refers to a structure made of an elastic material. The elastic material can be selected from rubber, and the structure of the elastomer 1 can adopt a cylindrical tube. Meanwhile, the elastomer 1 can be further provided with a notch 14 penetrating in the axial direction, which is used to expose the pipeline and adapt to pipelines with different diameters through the opening degree of the notch 14.

[0030] The elastomer 1 is used to be sleeved on the pipeline, which means that the pipeline extends out after penetrating the elastomer 1 in the axial direction of the elastomer 1, and the pipeline and the elastomer 1 are in interference fit, so as to realize the fixation of the damping structure. The extension direction of the deformation groove 11 can be a straight line, a zigzag, a curve or a combination of the above linear types. The elastomer 1 has multiple deformation directions, so that "there is a first included angle between the extension direction of the deformation groove 11 and the deformation direction of the elastomer 1, and the degree of the first included angle is greater than 0 degree and less than 180 degrees" means that there is a first included angle between the extension direction of at least part of the deformation groove 11 and at least one deformation direction of the elastomer 1. The first included angle here is only to distinguish from the second included angle in the following. "When the pipeline vibrates and causes the elastomer 1 to deform, the opposite two side walls of the deformation groove 11 contact and rub each other" means that the deformation of the elastomer 1 will cause the opposite two side walls of the deformation groove 11 to contact and generate a force that hinders each other's movement, which will reduce the deformation amount of the elastomer 1, and further inhibit the vibration of the pipeline, so as to ensure the service life of the pipeline.

[0031] In some embodiments, the deformation groove 11 does not penetrate the two ends of the elastomer 1, so as to drive the two side walls of the deformation groove 11 to approach each other.

[0032] It can be understood that due to the different cross sections of the pipeline, the deformation directions of the different cross sections are opposite and the deformation amounts are different, and then the two ends of the elastomer 1 will also deform in opposite directions, causing the elastomer 1 to deform like a twisted towel. During the deformation of the elastomer 1, the opposite two side walls of the deformation groove 11 with the above extension direction can generate a friction force opposite to the deformation force of the elastomer 1, so as to resist the deformation of the elastomer 1, and further resist the deformation of the pipeline, so as to achieve the purpose of damping and further improve the service life of the pipeline.

[0033] In some embodiments, as shown in Figure 1 and Figure 2 , the deformation groove 11 includes a plurality of groove segments 111 connected in sequence, and the plurality of groove segments 111 extend in different directions. The extension direction of at least one groove segment 111 and the axial direction of the elastomer 1 form a second included angle, and the degree of the second included angle is greater than 0 degree and less than 90 degrees.

[0034] It should be noted that the plurality of sequentially connected groove segments 111 of the deformation groove 11 refer to groove segments 111 having different extension directions formed by changing the extension direction. The second included angle is greater than 0 degrees and less than 90 degrees, which means that the extension direction of one of the groove segments 111 is inclined to the axial direction of the elastic body 1, and at the same time, is inclined to any horizontal cross section of the elastic body 1. In this way, the groove segments 111 gradually extend close to either end of the elastic body 1.

[0035] In some embodiments, as shown in Figure 2 , the extension directions of the two adjacent groove segments 111 are equal to the angle between the axial direction of the elastic body 1.

[0036] It should be noted that, when viewed from the radial direction of the elastic body 1, the angle between the extension direction of the two adjacent groove segments 111 and the axis of the elastic body 1 is equal. When the elastic body 1 is deformed, the relative two side walls of the plurality of groove segments 111 can generate friction forces in different directions to better adapt to the irregular deformation of the elastic body 1, improve the damping effect, and prolong the service life of the pipeline.

[0037] Exemplarily, as shown in Figure 2 , for any two adjacent groove segments 111, one of the groove segments 111 extends to the left and upward, and the other groove segment 111 is connected to the upper end of the above groove segment 111 and does not extend to the right and upward, that is, the extension direction of the two adjacent groove segments 111 is equal to the angle between the axial direction of the elastic body 1.

[0038] In some embodiments, as shown in Figure 1 and Figure 2 , the outer surface of the elastic body 1 is provided with a plurality of deformation grooves 11 arranged at intervals, the intervals between the plurality of deformation grooves 11 are equal or unequal, and the interval between the two opposite side walls of the groove segment 111 is greater than 0 mm and less than or equal to 0.5 mm.

[0039] It can be understood that by controlling the interval between the two opposite side walls of the groove segment 111 within the above range, the above side walls can respond more quickly to the deformation of the elastic body 1, thereby generating frictional contact, improving the damping effect, and prolonging the service life of the pipeline.

[0040] Exemplarily, the plurality of deformation grooves 11 are arranged at equal intervals along the circumferential direction of the elastic body 1; or, the plurality of deformation grooves 11 are arranged at equal intervals along the axial direction of the elastic body 1; or, part of the plurality of deformation grooves 11 are arranged at equal intervals along the circumferential direction of the elastic body 1, and the other part of the plurality of deformation grooves 11 are arranged at equal intervals along the axial direction of the elastic body 1.

[0041] The deformation groove 11 extends in a Z-shaped or S-shaped manner on the outer surface of the elastic body 1 in a direction from one end of the elastic body 1 to the other end.

[0042] In some embodiments, as shown in Figure 4 and Figure 5 , the groove segment 111 extends along a direction close to the axis of the elastic body 1, and the groove depth of the groove segment 111 is greater than the distance between the two opposite side walls of the groove segment 111.

[0043] It should be noted that the groove segment 111 extends along a direction close to the axis of the elastic body 1 means that the groove bottom of each groove segment 111 gradually approaches the axis of the elastic body 1. It can be understood that when the elastic body 1 deforms around its own axis, the position closer to the axis of the elastic body 1 on the elastic body 1 can deform faster, and by having the groove segment 111 with the above-mentioned extension direction, the approaching speed of the two opposite groove walls of the deformation groove 11 can be improved, and the friction force against the pipeline vibration can be generated in time.

[0044] Exemplarily, as shown in Figure 5 , the extension direction of the groove segment 111 along a direction close to the axis direction of the elastic body 1 and the radial direction of the elastic body 1 is greater than 0 degrees, that is, from the axial direction, the groove bottom extends obliquely to the radial direction of the elastic body 1. In this way, compared with extending along the radial direction of the elastic body 1, the area of the two side walls of the deformation groove 11 can be increased, and the force causing the deformation of the elastic body 1 can be better resisted, and the service life of the pipeline can be prolonged.

[0045] Further, as shown in Figure 4 , from the radial direction of the elastic body 1, the deformation groove 11 extends along a direction perpendicular to the axis direction of the elastic body 1.

[0046] In some embodiments, as shown in Figure 4 , a cavity 12 is arranged in the elastic body 1, and a heavy block 2 is arranged in the cavity 12, and the shape of the heavy block 2 is adapted to the shape of the cavity 12.

[0047] It should be noted that the shape of the heavy block 2 is adapted to the shape of the cavity 12 means that the shape of the heavy block 2 is consistent with the shape of the cavity 12, and the heavy block 2 completely fills the entire cavity 12. The density of the material of the heavy block 2 is greater than the density of the material of the elastic body 1, so that under the same volume, the heavy block 2 can increase the mass of the damping structure, thereby consuming more energy of the pipeline vibration, reducing the frequency and intensity of the pipeline vibration, avoiding resonance with the pipeline, and prolonging the service life of the pipeline.

[0048] In some embodiments, as shown in Figure 4 , a cavity 12 is arranged in the elastic body 1, and a plurality of moving bodies are arranged in the cavity 12.

[0049] It should be noted that the plurality of moving bodies arranged in the cavity 12 can move independently in the cavity 12. It can be understood that when the elastic body 1 vibrates with the pipeline, the plurality of moving bodies move under the action of inertia, and the plurality of moving bodies and the elastic body 1 will collide with each other. Both of the two collisions will consume the energy that causes the elastic body 1 to vibrate, absorb the pipeline vibration energy, avoid resonance with the pipeline, have better vibration reduction effect, and prolong the service life of the pipeline.

[0050] Further, the plurality of moving bodies can move freely in the cavity 12 independently of each other, that is, in addition to the obstruction between the inner wall of the cavity 12 and the moving bodies, there is no other structure to restrict the movement range of the plurality of moving bodies. The plurality of moving bodies has greater freedom to consume vibrations in different directions of the pipeline.

[0051] The moving bodies can be spherical bodies, cubes, or other objects with specific structures. The material of the moving bodies can be ethylene-propylene-diene rubber with good thermal insulation effect. Alternatively, the moving bodies can also be liquid. When liquid is used, the liquid can have a large viscosity coefficient, and the friction between the liquid and the inner wall of the cavity 12 can be used to consume the vibration energy of the pipeline.

[0052] In some embodiments, as shown in Figure 3 The vibration reduction structure further includes a thermal insulation layer 3 arranged between the elastic body 1 and the pipeline.

[0053] It should be noted that the elastic body 1 is provided with a mounting cavity 13 penetrating along the axial direction of the elastic body 1. The thermal insulation layer 3 is fixedly connected to the inner wall of the mounting cavity 13. The thermal conductivity of the material of the thermal insulation layer 3 is less than the thermal conductivity of the material of the elastic body 1. The thermal insulation layer 3 is used to insulate the heat of the pipeline and reduce the heat transferred to the elastic body 1, so as to ensure the structure of the elastic body 1 and the cavities 12 and the deformation grooves 11 on the elastic body 1, and avoid large deformation to affect use.

[0054] For example, the material of the thermal insulation layer 3 can be an NBR rubber-plastic heat insulation material mainly made of butadiene-acrylonitrile rubber.

[0055] Further, the elastic body 1 is provided with a notch 14 communicating with the mounting cavity 13. The notch 14 penetrates the elastic body 1 along the axial direction of the elastic body 1. When the pipeline passes through the vibration reduction structure, the opening of the notch 14 is controlled to adapt to pipelines with different diameters.

[0056] In some embodiments, as shown in Figure 4 The plurality of cavities 12 are symmetrically arranged along the direction from one end of the elastic body 1 to the other end of the elastic body 1.

[0057] It can be understood that, as the vibration amplitude of the pipeline is negatively correlated with the mass of the damping structure, when the number of the cavities 12 increases, the mass of the damping structure increases accordingly, and the damping effect is better. When the moving bodies are arranged in the cavities 12, the number of the moving bodies increases accordingly, and the damping effect is better.

[0058] In some embodiments, as shown in Figure 4 The elastic body 1 is provided with a plurality of cavities 12, at least one cavity 12 is provided with a weight 2 which is shaped to match the shape of the cavity 12, and at least one cavity 12 is provided with a plurality of moving bodies.

[0059] It can be understood that the damping effect is improved by increasing the mass of the damping structure and by energy consumption caused by collision.

[0060] In some embodiments, as shown in Figure 4 The cavity 12 is arranged on the side of the deformation groove 11 facing the axis of the elastic body 1, and the cavity 12 extends along the circumference of the elastic body 1. It can be understood that, compared with arranging the cavity 12 between adjacent deformation grooves 11, interference with the deformation of the deformation groove 11 can be avoided, and the cavity 12 is closer to the pipeline, and the damping effect is better.

[0061] The application also provides an air conditioner, which comprises the damping structure and the pipeline described above. The specific structure of the subject is described above. Since the air conditioner adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described here. The air conditioner further comprises a compressor, the pipeline is in communication with the compressor, and the pipeline is arranged in the damping structure.

[0062] It can be understood that, generally speaking, the pipeline connected to the compressor, such as the exhaust pipe, the suction pipe and the enthalpy increasing pipe, is prone to vibration and deformation. By installing the damping structure described above on the pipeline, the vibration and deformation of the pipeline can be resisted at the same time, thereby prolonging the service life of the pipeline.

In the description of the present application, the terms "first", "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
