Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and in particular to a vibration isolation structure for a compressor and an air conditioner outdoor unit. Background Art

[0002] An air conditioner is a cooling or heating device installed in an indoor space such as an office, living room or similar place to cool or heat the indoor space.

[0003] In the air-conditioning system, the compressor is the main source of vibration that causes the various components to vibrate. When the air-conditioning outdoor unit is working, the compressor vibrates during operation, and the vibration will be transmitted to the pipes connected to the compressor. During the operation of the compressor, a vibration isolation structure is generally installed at the bottom of the compressor to reduce the vibration of the compressor itself and reduce the vibration noise of the compressor. After the vibration of the compressor itself is reduced, the vibration of the pipes connected to it is also reduced.

[0004] At present, rubber vibration isolation structures are commonly used in household air-conditioning compressors, which are installed at the base or bracket position to isolate the vibration transmission from the active end to the passive end. While the vibration isolation structure plays a vibration isolation role, it is also necessary to consider the support performance. It cannot deform too much during transportation and falling, so as to avoid fatigue fracture and other problems caused by excessive deformation of the pipe system connected to the compressor. Household air-conditioning compressors are mainly rotary compressors, and the main vibration is the rotational vibration around the compressor axis. Rubber vibration isolation pads are usually used. In order to improve the vibration isolation performance, softer materials are generally selected, or part of the material is cut off from the inner and outer walls to reduce the stiffness of the vibration isolation structure, that is, to reduce the system's natural frequency, thereby increasing the ratio of the system vibration frequency to the system's natural frequency and improving the vibration isolation effect. However, due to the need to ensure support performance, the range of stiffness reduction is limited, resulting in limited optimization of vibration isolation performance, resulting in general vibration isolation and vibration reduction effects of the vibration isolation structure. Utility Model Content

[0005] The utility model solves one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the present application aims to provide a vibration isolation structure for a compressor, which converts the tangential vibration portion of the compressor into axial sliding, and improves the vibration reduction performance of the vibration isolation structure through the friction damping generated by the mutual sliding between the elastic part and the connecting part.

[0023] In the technical solution, the radial vibration force of the compressor is transmitted to the elastic member through the mounting plate, and the tangential vibration part of the compressor is converted into axial sliding through the sliding friction between the elastic member and the connecting part, thereby reducing the vibration of the compressor through friction damping.

[0059] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0060] In the present application, the vibration isolation structure for the compressor includes a mounting plate, a vibration damping member and an elastic member. The compressor is mounted on the mounting plate. The vibration of the compressor is transmitted to the vibration damping member and the elastic member through the mounting plate. The sliding friction between the elastic member and the mounting part disperses the vibration of the compressor.

[0061] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0062] As attached Figures 1 to 5 As shown, in an illustrative embodiment of a vibration isolation structure for a compressor of the utility model, the vibration isolation structure for the compressor includes a mounting plate, and the mounting plate is used to mount the compressor.

[0063] The vibration isolation structure for the compressor comprises a mounting hole, which is opened on the mounting plate.

[0064] The vibration isolation structure for the compressor includes a vibration damper 100, a placement cavity 200 is provided on the side of the vibration damper 100 facing the mounting plate, a connecting portion 101 is provided on the inner bottom wall of the placement cavity 200, and the connecting portion 101 passes through the mounting hole. The vibration damper 100 plays the role of primary vibration isolation and limiting support.

[0065] The vibration isolation structure for the compressor includes an elastic member 300, which is arranged in the placement cavity 200. The elastic member 300 includes a first deformation portion 301. The first deformation portion 301 is slidably connected to the connecting portion 101 along the length direction of the connecting portion 101 at one end close to the mounting plate, and the first deformation portion 301 passes through the mounting hole.

[0066] The elastic member 300 includes a second deformable portion 302 , one end of which is connected to an end of the first deformable portion 301 away from the mounting plate, and the end of the second deformable portion 302 away from the first deformable portion 301 is slidably connected to the connecting portion 101 along the length direction of the connecting portion 101 .

[0067] A deformation cavity 400 is formed between the first deformation portion 301 , the second deformation portion 302 and the connecting portion 101 .

[0068] The radial vibration force of the compressor drives the mounting plate to move, and the mounting plate squeezes the first deformation part 301 and the second deformation part 302 to deform the deformation cavity 400, thereby driving one end of the first deformation part 301 and one end of the second deformation part 302 to slide along the length direction of the connecting part 101 to disperse the radial vibration force of the compressor.

[0069] In the prior art, rubber vibration isolation pads are commonly used in compressors and installed at the base or bracket of the compressor, mainly to isolate the vibration transmission from the active end to the passive end. In order to improve the vibration isolation performance, softer materials are generally selected as much as possible, or part of the material is cut off from the inner and outer walls of the rubber vibration isolation pad to reduce the stiffness of the vibration isolation pad, that is, reduce the system's natural frequency, thereby increasing the ratio of the system vibration frequency to the system's natural frequency and improving the vibration isolation effect.

[0070] Since the supporting performance of the rubber vibration isolation pad must be guaranteed, the reduction range of the stiffness of the vibration isolation pad is limited, resulting in limited optimization of the vibration isolation performance.

[0071] Through the above technical solution, a deformation cavity 400 is formed between the first deformation part 301, the second deformation part 302 and the connecting part 101, and the radial vibration force of the compressor is transmitted to the first deformation part 301 and the second deformation part 302 through the mounting plate. Through the sliding friction between the first deformation part 301 and the second deformation part 302 and the connecting part 101, the tangential vibration part of the compressor is converted into axial sliding, and the vibration of the compressor is reduced through friction damping.

[0072] As attached Figures 6 to 9 As shown, in some embodiments, the elastic member 300 may include a first sliding portion 303, which is connected to an end of the first deformation portion 301 away from the second deformation portion 302, and the first sliding portion 303 is slidably connected to the connection portion 101 along the length direction of the connection portion 101 toward one side of the connection portion 101.

[0073] The elastic member 300 may include a second sliding portion 304 . The second sliding portion 304 is connected to an end of the second deformable portion 302 away from the first deformable portion 301 . The second sliding portion 304 is slidably connected to the connecting portion 101 .

[0074] As attached Figures 10 to 12 As shown, the elastic member 300 may include a vibration transmission part 305, the outer peripheral wall of the vibration transmission part 305 abuts against the inner peripheral wall of the mounting hole, the vibration transmission part 305 is connected to an end of the first deformation part 301 away from the first sliding part 303, and the vibration transmission part 305 is connected to an end of the second deformation part 302 away from the first sliding part 303.

[0075] In some embodiments, the connecting portion 101 is cylindrical, the vibration damping member 100 is cylindrical, the connecting portion 101 and the vibration damping member 100 are coaxially arranged, and the placement cavity 200 is coaxially arranged with the connecting portion 101 .

[0076] In some embodiments, the vibration damping member 100 is placed vertically, and the vibration damping member 100 includes a supporting portion, and a placement cavity 200 is formed between the supporting portion and the connecting portion 101, and the height of the supporting portion is lower than the height of the connecting portion 101. On the one hand, the supporting portion is used to support the compressor to ensure the installation stability of the compressor; on the other hand, the supporting portion is also used to transfer the vibration of the compressor from the mounting plate to the supporting portion, thereby improving the vibration reduction effect.

[0077] A placement cavity 200 is formed between the support portion and the connection portion 101 , so that the vibration damping member 100 is more likely to be squeezed and deformed when subjected to compressor vibration, thereby absorbing more vibration energy, thereby better improving the vibration reduction and vibration isolation effects of the vibration damping member 100 .

[0078] In some embodiments, the vibration damper 100 is made of rubber material, and rubber has both a certain hardness and a certain elasticity. By setting the vibration damper 100 to be made of rubber material, it can not only provide better support to ensure the installation stability of the compressor, but also make the vibration damper 100 have a vibration damping effect, thereby further improving the vibration damping effect of the vibration damping structure.

[0079] In some embodiments, the vibration damping member 100 is made of rubber that is wear-resistant, high-temperature-resistant, and corrosion-resistant, so that the vibration damping member 100 has a better vibration damping effect.

[0080] In some embodiments, the elastic member 300 is made of metal or polymer material with elasticity, and is easily elastically deformed under the action of vibration force.

[0081] The elastic member 300 and the vibration damping member 100 are made of different materials, which further staggers the natural frequencies of the elastic member 300 and the vibration damping member 100, so that the elastic member 300 and the vibration damping member 100 do not resonate, thereby attenuating the generation of vibration and reducing noise.

[0082] In some embodiments, the first sliding part 303 is an arc-shaped plate, the inner wall of the first sliding part 303 is in contact with the outer wall of the connecting part 101, and the structure of the second sliding part 304 is the same as that of the first sliding part 303, which is convenient for batch processing to improve processing efficiency and reduce processing costs.

[0083] In some embodiments, the vibration transmitting portion 305 is annular in structure, a portion of the vibration transmitting portion 305 is inserted into the mounting hole, and another portion of the vibration transmitting portion 305 is inserted into the placement cavity 200 .

[0084] In some embodiments, a plurality of first sliding parts 303 are provided at circumferential intervals along the vibration transmitting part 305, and a plurality of second sliding parts 304 are provided at circumferential intervals along the vibration transmitting part 305. The first sliding parts 303 and the second sliding parts 304 are arranged in a one-to-one correspondence, which facilitates the first sliding parts 303 and the second sliding parts 304 to slide along the outer peripheral wall of the connecting part 101, thereby increasing the contact area between the first sliding parts 303, the second sliding parts 304 and the connecting part 101, and thereby increasing the friction damping of the contact surface.

[0085] In some embodiments, the number of the first sliding parts 303 and the number of the second sliding parts 304 are the same, the distance between any two adjacent first sliding parts 303 is the same, and the distance between any two adjacent second sliding parts 304 is the same.

[0086] Any two adjacent first sliding parts 303 are spaced apart, and any two adjacent second sliding parts 304 are spaced apart, so as to avoid collision between the first sliding parts 303 or between the second sliding parts 304 and abnormal noise during the operation of the compressor.

[0087] The multiple first sliding parts 303 and the multiple second sliding parts 304 can both play a role in preventing the horizontal vibration of the compressor. The multiple first sliding parts 303 and the multiple second sliding parts 304 increase the contact area with the connecting part 101 and improve the stability of the compressor.

[0088] In some embodiments, a guide portion 800 is provided on one side of the first sliding portion 303 and the second sliding portion 304 facing the connecting portion 101 , and the guide portion 800 is used to guide the first sliding portion 303 and the second sliding portion 304 to slide along the outer peripheral wall of the connecting portion 101 .

[0089] In some embodiments, the first sliding portion 303 , the first deformable portion 301 , the second deformable portion 302 , and the second sliding portion 304 are an integrally formed structure, which is easy to process and has low cost.

[0090] In some embodiments, the guide portion 800 is in the shape of an elongated strip. The length, width and surface roughness of the guide portion 800 affect the friction between the guide strip and the connecting portion 101 and the vibration performance, and can be designed according to the actual vibration magnitude.

[0091] In some embodiments, a guide groove is provided on the outer wall of the connecting part 101, and the guide part 800 is arranged in the guide groove. The guide groove can limit the position of the guide part 800, and at the same time increase the degree of fit between the first sliding part 303, the second sliding part 304 and the connecting part 101, thereby preventing the sliding position of the first sliding part 303 and the second sliding part 304 from shifting when vibrated.

[0092] In some implementations, a plurality of guide portions 800 are disposed at intervals on each first sliding portion 303 , and a plurality of guide portions 800 are disposed at intervals on each second sliding portion 304 .

[0093] In some embodiments, the vibration isolation mechanism for the compressor may include a friction member 500, which is hollow and has an inner circumferential wall that fits the outer circumferential wall of the connecting portion 101, and the first sliding portion 303 and the second sliding portion 304 that are slidably connected to the outer circumferential wall of the friction member 500.

[0094] A relative displacement occurs between the friction member 500 and the connecting portion 101 , which reduces vibrations through friction; a relative displacement occurs between the elastic member 300 and the friction member 500 , which reduces vibrations through friction.

[0095] In some embodiments, the friction member 500 is cylindrical and is sleeved on the connecting portion 101. The friction member 500 and the connecting portion 101 are interference fit. The friction between the friction member 500 and the connection also plays a vibration reduction role.

[0096] Existing vibration isolation pads are mostly made of materials such as EPDM rubber and natural rubber. The damping coefficient of the material is relatively small. The ability of the vibration isolation pad to convert mechanical energy into heat energy through deformation and internal friction of the material is limited, and the vibration reduction effect is relatively poor.

[0097] In the present application, by providing the friction member 500 and the elastic member 300, both the inner and outer walls of the friction member 500 can play a vibration reduction role through friction, so that the vibration reduction effect of the vibration reduction structure is good and the vibration noise of the compressor is low.

[0098] In some embodiments, a first limiting portion 501 is provided on the side of the friction member 500 close to the compressor, and a second limiting portion 502 is provided on the side of the friction member 500 away from the compressor. The first limiting portion 501 and the second limiting portion 502 are used to limit the sliding position of the elastic member 300.

[0099] The first limiting portion 501 can also prevent the first sliding portion 303 from touching the mounting plate and causing damage to the mounting plate; the second limiting portion 502 can also prevent the second sliding portion 304 from directly acting on the vibration damping member 100 and causing damage to the vibration damping member 100.

[0100] In some embodiments, the first limiting portion 501 is an annular structure, and the second limiting portion 502 is an annular structure.

[0101] In some embodiments, only the first deformation part 301 and the first sliding part 303 are provided in the placement cavity 200. The first deformation part 301 is connected to the mounting hole. The vibration of the compressor drives the mounting plate to move. The movement of the mounting plate squeezes the first deformation part 301 to deform. The first deformation part 301 drives the first sliding part 303 to slide along the outer peripheral wall of the connecting part 101, thereby dispersing the vibration force of the compressor.

[0102] In some embodiments, only the second deformation portion 302 and the second sliding portion 304 are provided in the placement cavity 200. The second deformation portion 302 is connected to the mounting hole. The vibration of the compressor drives the mounting plate to move. The movement of the mounting plate squeezes the second deformation portion 302 to deform. The second deformation portion 302 drives the second sliding portion 304 to slide along the outer peripheral wall of the connecting portion 101, thereby dispersing the vibration force of the compressor.

[0103] As attached Figures 13 to 16 As shown, in some embodiments, the placement cavity 200 includes a first chamber 201 and a second chamber 202 which are interconnected, the first chamber 201 is close to the compressor, and the second chamber 202 is far away from the compressor, the second limiting portion 502 is arranged in the second chamber 202, and the side of the second limiting portion 502 facing the first chamber 201 abuts against the inner wall of the second chamber 202, and a spring 600 is provided in the second chamber 202, and the spring 600 is located on the side of the second limiting portion 502 away from the first chamber 201.

[0104] Two ends of the spring 600 abut against a side of the second limiting portion 502 away from the first chamber 201 and a bottom wall of the second chamber 202 , respectively. The spring 600 is coaxially arranged with the second chamber 201 .

[0105] The spring 600 plays a role in vibration isolation. The stiffness of the spring 600 affects the vibration isolation performance. The stroke of the spring 600 affects the limit requirements and can be designed according to the actual vibration characteristics. The design of the spring 600 performs secondary vibration isolation, which improves the vibration reduction and isolation performance of the axial and radial vibrations of the vibration isolation structure.

[0106] In some embodiments, a third blocking portion is provided on the outer peripheral wall of the connecting portion 101 on the side close to the compressor, and the third blocking portion is used to block the sliding distance of the first sliding portion 303 in the direction close to the compressor.

[0107] In addition, the present application also provides a vibration isolation structure for a compressor, which includes a mounting plate, and the mounting plate is used to install the compressor.

[0108] The vibration isolation structure mounting hole for the compressor is opened on the mounting plate.

[0109] A vibration-isolating structure vibration-damping component 100 for a compressor is provided with a placement cavity 200 on one side of the vibration-damping component 100 facing the mounting plate, and a connecting portion 101 is provided on the inner bottom wall of the placement cavity 200, and the connecting portion 101 passes through the mounting hole.

[0110] The compressor uses an elastic member 300 of a vibration isolation structure. The elastic member 300 is disposed in the placement cavity 200. The elastic member 300 passes through the mounting hole. The elastic member 300 is bent toward the side away from the connecting portion 101 to form a deformation cavity 400. The side of the elastic member 300 close to the connecting portion 101 is slidably connected to the connecting portion 101 along the length direction of the connecting portion 101.

[0111] The radial vibration force of the compressor drives the mounting plate to move, and the mounting plate squeezes the elastic member 300 to deform the deformation cavity 400, thereby driving the elastic member 300 to slide along the length direction of the outer peripheral wall of the connecting portion 101 to disperse the radial vibration force of the compressor.

[0112] Through the above technical solution, the radial vibration force of the compressor is transmitted to the elastic member 300 through the mounting plate, and the tangential vibration part of the compressor is converted into axial sliding through the sliding friction between the elastic member 300 and the connecting part 101, thereby reducing the vibration of the compressor through friction damping.

[0113] In some embodiments, the elastic member 300 includes a first deformable portion 301 and a second deformable portion 302 that are connected to each other, and a deformation cavity 400 is formed between the first deformable portion 301 , the second deformable portion 302 and the connecting portion 101 .

[0114] One end of the first deformable portion 301 away from the second deformable portion 302 is slidably connected to the connecting portion 101 along a direction perpendicular to the mounting plate, and one end of the second deformable portion 302 away from the first deformable portion 301 is slidably connected to the connecting portion 101 along a direction perpendicular to the mounting plate.

[0115] In some embodiments, the angle between the first deformation portion 301 and the second deformation portion 302 is an obtuse angle. When the mounting plate squeezes the first deformation portion 301, the deformation cavity 400 is easily deformed, so that the elastic member 300 slides along the outer peripheral wall of the connecting portion 101, thereby reducing the vibration of the compressor.

[0116] In some embodiments, the elastic member 300 may include a first sliding portion 303, which is connected to one end of the first deformation portion 301 away from the second deformation portion 302, and the first sliding portion 303 is slidably connected to the connection portion 101 along the length direction of the connection portion 101 toward one side of the connection portion 101.

[0118] The elastic member 300 may include a vibration transmission part 305, the outer peripheral wall of the vibration transmission part 305 abuts against the inner peripheral wall of the mounting hole, the vibration transmission part 305 is connected to one end of the first deformation part 301 away from the first sliding part 303, and the vibration transmission part 305 is connected to one end of the second deformation part 302 away from the first sliding part 303.

[0119] In some embodiments, a guide portion 800 is provided on one side of the first sliding portion 303 and the second sliding portion 304 facing the connecting portion 101 , and the guide portion 800 is used to guide the first sliding portion 303 and the second sliding portion 304 to slide along the outer peripheral wall of the connecting portion 101 .

[0120] In some embodiments, the vibration isolation mechanism for the compressor may include a friction member 500, which is hollow and has an inner circumferential wall that fits the outer circumferential wall of the connecting portion 101, and the first sliding portion 303 and the second sliding portion 304 that are slidably connected to the outer circumferential wall of the friction member 500.

[0121] In some embodiments, a connection hole 700 is provided on one side of the connection portion 101 facing the mounting plate. The connection hole 700 is connected to the mounting plate via a connecting piece, which makes installation quick and easy.

[0122] In some embodiments, the mounting hole is a circular hole, and the side of the placement cavity 200 close to the mounting hole is also a circular cavity, and the diameter of the circular hole is the same as the diameter of the circular cavity.

[0123] The elastic member 300 includes a first deformation portion 301 and a second deformation portion 302 which are connected to each other. One end of the first deformation portion 301 away from the second deformation portion 302 is slidably connected to the inner wall of the mounting hole along a direction perpendicular to the mounting plate, and one end of the second deformation portion 302 away from the first deformation portion 301 is slidably connected to the inner wall of the placement cavity 200 along a direction perpendicular to the mounting plate.

[0124] The first sliding portion 303 is connected to one end of the first deformable portion 301 away from the second deformable portion 302 . The side of the first sliding portion 303 away from the connecting portion 101 is slidably connected to the inner wall of the mounting hole along the length direction of the connecting portion 101 .

[0125] The second sliding portion 304 is connected to one end of the second deformable portion 302 away from the first deformable portion 301 . The side of the second sliding portion 304 away from the connecting portion 101 is slidably connected to the inner wall of the placement cavity 200 along the length direction of the connecting portion 101 .

[0126] The radial vibration force of the compressor is transmitted to the elastic member 300 through the mounting plate. The sliding friction between the elastic member 300 and the inner wall of the placement chamber 200 converts the tangential vibration of the compressor into axial sliding, and the vibration of the compressor is reduced by friction damping.

[0127] In some embodiments, the connection hole 700 passes through the vibration damping member 100, and the connection hole 700 is sleeved on the stud, and the stud is connected to the mounting plate. The connection part 101 can reduce the vibration transmission from the mounting plate to the stud, and the vibration damping effect is good and the vibration noise is low.

[0128] The provision of the connection hole 700 can increase the deformation range of the vibration-damping member 100, thereby increasing the elasticity of the vibration-damping member 100 and improving the vibration-damping effect of the vibration-damping structure.

[0129] In addition, the present application also provides an air-conditioning outdoor unit, including a shell and a compressor, wherein the compressor is arranged in the shell, and is characterized in that a vibration isolation mechanism for the compressor is also provided in the shell, and the compressor is installed on a mounting plate.

[0130] Through the above technical solution, the compressor is installed on the mounting plate, and the mounting plate and the compressor are connected by a vibration isolation mechanism. The radial vibration of the compressor is dispersed through friction damping, thereby improving the vibration isolation effect and reducing the vibration of the air conditioner outdoor unit.

[0131] The household air-conditioning compressor is mainly a rotary compressor, and its main vibration is the rotational vibration around the compressor axis. The rotational vibration acts on the vibration transmitting part 305, and the first deformation part 301 and the second deformation part 302 are deformed by force, driving the first sliding part 303 and the second sliding part 304 to move axially, rubbing against the friction part 500, thereby playing a vibration reduction role.

[0132] The first sliding part 303 and the second sliding part 304 can drive the friction member 500 to move, and the friction between the friction member 500 and the connecting part 101 also plays a vibration reduction role. When the friction member 500 moves, it also acts on the spring 600 in the second chamber 202, and the spring 600 plays a secondary vibration isolation effect, further improving the vibration isolation performance.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
