[0002] In the field of air-conditioning refrigeration industry, the compressor is the core component of the refrigeration system. Therefore, the use and maintenance of compressor components are crucial. During the installation and use of the compressor, the fixing rubber pad is an important component to ensure the stable operation of the compressor, reduce vibration and noise. In the current market, through the combined structural form of bolt columns, rubber shock pads and compressor feet, this design alleviates the vibration problem during the operation of the compressor to a certain extent, but there are still obvious limitations. The outdoor unit of the air conditioner is generally placed outdoors. Over time, the rubber pad is prone to aging, the damping coefficient decreases, and the damping protection effect on the compressor is lost, resulting in large vibration during the start-up and operation of the compressor. At present, there is no relevant detection component for the failure of the compressor foot pad. Therefore, it is easy to cause problems such as excessive vibration of the compressor and fracture of the pipeline connected to the compressor.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside of the contour of each component itself.

[0031] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned "below other devices or structures" or "below other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present utility model.

[0033] Referring to Figures 1-7 As shown, according to an embodiment of the present utility model, a damping device is provided, including:

[0034] A first fixing member 1, the first fixing member 1 is sleeved on a vibrating member 7; a longitudinal elastic component 3, the longitudinal elastic component 3 is disposed on an installation surface 6 of the vibrating member 7, a second fixing member 2 is disposed on the longitudinal elastic component 3, and the second fixing member 2 is connected to the first fixing member 1 through a transverse elastic component 4. In this technical solution, during use, the positions of the first fixing member 1 and the second fixing member 2 can be adjusted according to the height of the vibrating member 7. When the damping device of the present utility model is applied to a compressor, it can also reduce problems such as excessive vibration at the top of the compressor during startup; when the vibrating member 7 undergoes transverse vibration, the transverse elastic component 4 is used to damp the transverse vibration. When the vibrating member 7 undergoes longitudinal vibration, the first fixing member 1 drives the second fixing member 2 to perform longitudinal movement through the transverse elastic component 4, so that the second fixing member 2 performs longitudinal damping through the longitudinal elastic component 3, which can solve the problem of the compressor foot pad failure after the unit is sold, avoid problems such as excessive vibration of the compressor caused by the damping failure of the compressor foot pad, and can make up for the damping failure caused by wear and aging of the compressor foot pad, and solve the problem of excessive vibration of the compressor caused by the wear and failure of the compression foot pad.

[0035] In some embodiments, the first fixing member 1 and the second fixing member 2 are annular, the first fixing member 1 is located inside the second fixing member 2, and along the circumferential direction of the second fixing member 2, the second fixing member 2 is connected to the first fixing member 1 through a plurality of the transverse elastic components 4, and a plurality of longitudinal elastic components 3 are disposed on the second fixing member 2. In this technical solution, the first fixing member 1 and the second fixing member 2 are annular. Preferably, the first fixing member 1 is sleeved inside the second fixing member 2, and there is a gap between the first fixing member 1 and the second fixing member 2. The first fixing member 1 can adopt a multi-segment structure, and the multi-segment first fixing members 1 are sequentially connected to form an annular structure. Specifically, the first fixing member 1 can adopt a three-segment structure. The number of the transverse elastic components 4 and the longitudinal elastic components 3 is 3. Each segment of the first fixing member 1 corresponds to a transverse elastic component 4 and a longitudinal elastic component 3. Adjacent segments of the first fixing member 1 can be connected by screws, buckles or welding, etc. Of course, other connection methods are also possible.

[0036] When the vibration reduction device of the utility model is applied to a compressor, the transverse elastic component 4 and the longitudinal elastic component 3 are used in combination to achieve the vibration reduction effect on the compressor in the horizontal and vertical directions, and solve the problem of vibration reduction failure caused by aging and wear of the compressor foot pads of the after-sales unit; at the same time, the problem of excessive vibration when the compressor is started is reduced, and at the same time, the stiffness of the vibration reduction device can be adjusted by adjusting the preload force of the spring to adapt to the vibration conditions of the compressor in different scenarios.

[0037] In some embodiments, along the circumference of the second fixing member 2, a plurality of through holes 18 are provided on the second fixing member 2, and the through holes 18 correspond to the transverse elastic components 4 one by one; the transverse elastic components 4 include a connecting member 10, one end of the connecting member 10 is connected to the first fixing member 1, and the other end of the connecting member 10 passes through the through hole 18, and the connecting member 10 can move in the through hole 18, and a first elastic member 8 is provided on the connecting member 10. In this technical solution, the first elastic member 8 is a spring, one end of the connecting member 10 is fixedly connected to the outer peripheral wall of the first fixing member 1, and the other end passes through the through hole 18. When the vibrating member 7 vibrates transversely, the vibrating member 7 drives the first fixing member 1 to move transversely, and the connecting member 10 performs telescopic movement in the through hole 18. On the connecting member 10 in the movement direction of the first fixing member 1, the first elastic member 8 is compressed by the first fixing member 1, thereby achieving transverse vibration reduction.

[0038] In some embodiments, the connecting member 10 is sleeved with a first stopper 9, and the first stopper 9 is located between the first elastic member 8 and the second fixing member 2. In this technical solution, the connecting member 10 and the first stopper 9 can be connected by threading, and by adjusting the position of the first stopper 9, the preload of the spring can be adjusted, and the stiffness of the shock absorbing device can be adjusted; when the vibrating member 7 produces horizontal shaking, it will be transmitted to the first fixing member 1, and the first fixing member 1 will drive the connecting member 10 to move, and the connecting member 10 will perform telescopic movement along the through hole 18. When the connecting member 10 moves, the first stopper 9 will connect the first elastic member 8 on the connecting member 10, and absorb the vibration capacity of the vibrating member 7 through the deformation of the first elastic member 8 on the connecting member 10, thereby reducing the vibration of the vibrating member 7.

[0039] In some embodiments, the longitudinal elastic component 3 includes a fixing post 14, the fixing post 14 is disposed on the mounting surface 6 of the vibrating member 7, a second limiting member 15 is arranged on the fixing post 14, a movable member 11 is sleeved on the fixing post 14, and along the axial direction of the fixing post 14, the movable member 11 can move on the fixing post 14. A second elastic member 16 is arranged on the fixing post 14, and the second elastic member 16 is located between the movable member 11 and the second limiting member 15. The movable member 11 is connected to the second fixing member 2. In this technical solution, the second elastic member 16 is a spring. When the vibrating member 7 generates longitudinal swaying, the first fixing member 1 drives the second fixing member 2 to move longitudinally through the connecting member 10, and the second fixing member 2 drives the movable member 11 to move up and down along the axial direction of the fixing post 14, so that the movable member 11 compresses the second elastic member 16 toward the second limiting member 15. The longitudinal vibration energy of the vibrating member 7 is absorbed through the deformation of the second elastic member 16, thereby weakening the vibration of the vibrating member 7.

[0040] In some embodiments, a third limiting member 13 and a third elastic member 12 are further arranged on the fixing post 14. The movable member 11 is located between the second limiting member 15 and the third limiting member 13, and the third elastic member 12 is located between the third limiting member 13 and the movable member 11, and the movable member 11, the third elastic member 12, and the third limiting member 13 are connected in sequence. In this technical solution, the third elastic member 12 is a spring. Preferably, the movable member 11, the second elastic member 16, and the second limiting member 15 are connected in sequence, and the movable member 11, the third elastic member 12, and the third limiting member 13 are connected in sequence. When the vibrating member 7 generates longitudinal swaying and moves downward, the first fixing member 1 drives the second fixing member 2 to move longitudinally through the connecting member 10, and the second fixing member 2 drives the movable member 11 to move downward along the axial direction of the fixing post 14, so that the movable member 11 compresses the second elastic member 16 toward the second limiting member 15. Moreover, the movable member 11 stretches the third elastic member 12 downward. When moving upward, the movable member 11 stretches the second elastic member 16, and moreover, the movable member 11 compresses the third elastic member 12 upward. The longitudinal vibration energy of the vibrating member 7 is absorbed through the deformation of the second elastic member 16 and the third elastic member 12, thereby weakening the vibration of the vibrating member 7.

[0041] In some embodiments, threads can be arranged on the fixing post 14. The second limiting member 15 and the fixing post 14, and the third limiting member 13 and the fixing post 14 can adopt threaded connections. By adjusting the positions of the third limiting member 13 and the second limiting member 15, the compression and stretching amounts of the second elastic member 16 and the third elastic member 12 can be adjusted, and further the adjustment of the longitudinal damping stiffness can be achieved.

[0042] In some embodiments, the second fixing member 2 includes a plurality of leaf springs 5, and the plurality of leaf springs 5 are sequentially connected to form an annular structure, and two adjacent leaf springs 5 are connected by the longitudinal elastic component 3. In this technical solution, when the vibrating member 7 generates horizontal shaking, it will be transmitted to the first fixing member 1, and the first fixing member 1 will drive the connecting member 10 to move, and the connecting member 10 will perform telescopic movement along the through hole 18. When the connecting member 10 moves, the first limit member 9 will connect the first elastic member 8 on the connecting member 10, and absorb the vibration capacity of the vibrating member 7 through the deformation of the first elastic member 8 on the connecting member 10, thereby weakening the vibration of the vibrating member 7, and at the same time, its energy will be transmitted to the corresponding leaf spring 5, and the leaf spring 5 will further achieve transverse compressor vibration reduction through further deformation. Preferably, two adjacent leaf springs 5 can be connected by means of snaps, bolts, etc.

[0043] The utility model also provides a compressor, comprising the above-mentioned vibration reduction device.

[0044] In some embodiments, the compressor serves as the vibrating member 7, the compressor is mounted on the mounting surface 6 via a foot pad 17, and the longitudinal elastic component 3 is disposed on the foot pad 17. In this technical solution, the longitudinal elastic component 3 is disposed on the foot pad 17, and is connected to the longitudinal elastic component 3 via the foot pad 17, so as to further reduce the longitudinal vibration.

[0045] Traditional compressor rubber foot pads are directly put on the fixed studs, and their lateral deformation is limited, and their lateral shock absorption effect is poor. If the compressor rubber foot pads are aged and worn, the lateral vibration reduction is more likely to fail. Therefore, the vibration reduction device of the utility model can make up for the lateral vibration absorption requirements of the compressor when the rubber foot pads fail, and its lateral shock absorption effect exceeds that of the original rubber foot pads.

[0046] The vibration of the compressor in the longitudinal direction, when moving downward, the first fixing member 1 drives the second fixing member 2 to move longitudinally through the connecting member 10, and the second fixing member 2 drives the movable member 11 to move downward along the axial direction of the fixing column 14, so that the movable member 11 compresses the second elastic member 16 toward the second limit member 15, and the movable member 11 stretches the third elastic member 12 downward, and when moving upward, the movable member 11 stretches the second elastic member 16, and the movable member 11 compresses the third elastic member 12 upward, and absorbs the longitudinal vibration capacity of the vibrating member 7 through the deformation of the second elastic member 16 and the third elastic member 12, thereby reducing the vibration of the vibrating member 7. In particular, the rubber foot pads of the compressor are prone to aging and wear, and the shock absorbing effect of the foot pads in the longitudinal direction is very easy to fail, resulting in excessive vibration of the compressor, and there is no corresponding detection mechanism, which is easy to cause pipeline rupture and other problems; the vibration reduction device of the utility model can solve such problems well. The compressor of the utility model can be adapted to rubber foot pads with a wider range of shock absorption coefficients, and the difference can be compensated by adjusting the stiffness of the vibration reduction device.

[0047] The present utility model also provides an air conditioner, which includes the above-mentioned compressor.

[0048] It is easily understood by those skilled in the art that, on the premise of no conflict, the advantageous technical features of the above-mentioned various methods can be freely combined and superimposed.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. The above is only the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and variations can be made without departing from the technical principle of the present utility model, and these improvements and variations should also be regarded as within the protection scope of the present utility model.
