The air conditioner includes a duct system including a plurality of branch ducts. High frequency vibration and low frequency vibration exist in the pipeline. The high frequency vibration mainly causes low cycle fatigue damage of the pipeline, and the low frequency vibration mainly causes low frequency noise, which causes noise of the air conditioner. In the prior art, a vibration source is isolated by adopting air mostly through pipeline vibration, the measures are to avoid the interference and the contact of pipelines in the design, and a wire clamp is added in the middle of a long pipe to improve the rigidity of the long pipe so as to avoid high-frequency vibration; however, low frequency vibration in the piping still exists, and low frequency noise becomes a main noise source of the air conditioner.
The pipelines on the air conditioner at least comprise a first pipeline and a second pipeline, and the first pipeline and the second pipeline have parallel pipe sections. The invention provides a vibration isolation assembly by utilizing the structural characteristics, so as to solve the problem of low-frequency vibration between air conditioner pipeline systems. The pipeline is coupled and connected in parallel by utilizing the nonlinear characteristics of the pressure lever and the rubber piece, and the pressure lever is pressed and pre-bent under the critical buckling load under the action of the rubber piece and the clamping piece so as to have deflection, so that the vibration isolation assembly can resist low-frequency vibration, absorb the low-frequency vibration of the pipeline, avoid transmitting the low-frequency noise to the air conditioner and achieve the purpose of reducing the noise of the air conditioner.
Specifically, the present application proposes a vibration isolation assembly, as shown in fig. 1, comprising:
a first clamping member 100, wherein the first clamping member 100 is connected with the first pipeline 600;
an elastic member 200, wherein the elastic member 200 is respectively connected to the first pipeline 600 and the second pipeline 700, and is spaced apart from the first clamping member 100 in the axial direction of the first pipeline 600; and
one end of the first pressing rod 300 is connected to the first clamping member 100, one end of the first pressing rod 300 is connected to the elastic member 200, and the first pressing rod 300 is in a bending state.
In the technical solution provided in the embodiment of the present invention, the vibration isolation assembly includes a first clamping member 100, an elastic member 200, and a first pressing rod 300. The first clamping member 100 is connected with the first pipeline 600; elastic member 200 is connected to first pipeline 600 and second pipeline 700, respectively; the elastic member 200 and the first clamping member 100 are arranged at intervals in the axial direction of the first pipeline 600, and a space is left for pre-bending of the first compression bar 300; one end of the first pressing rod 300 is connected to the first clamping member 100, the other end of the first pressing rod 300 is connected to the elastic member 200, and the first pressing rod 300 is in a bending state. Since the first pressing rod 300 is in a bending state and the elastic member 200 has nonlinearity, when low-frequency vibration occurs in the first pipeline 600, at least part of the excitation of the low-frequency vibration is absorbed by the vibration isolation assembly, and the transmission of low-frequency noise to the air conditioner is reduced.
It should be noted that, in general, when the first pressing rod 300 is in the bending state, the first pressing rod has a maximum deflection value (the first deflection) which is the deflection value of the first pressing rod 300 in the quasi-zero stiffness range, so that the vibration isolation assembly can reach the quasi-zero state and can resist low-frequency vibration. The value of the first deflection can be obtained by a finite element method and an experimental method. Generally, the first deflection is related to the axial length of the first compression bar 300, the stiffness of the resilient member 200, and the radial spacing of the first and second conduits 600, 700. The inventor of the present invention has found that the maximum deflection value of the first pressing rod 300 is generally between 1 and 3mm when the first pressing rod is in a bending state.
The first pressure lever is put in a bent state by applying pressure thereto.
It should be noted that the first clamping member 100 can be sleeved on the first pipeline 600, and the first clamping member 100 can be locked on the first pipeline 600 by a pair of fasteners. It can be understood that the first clamping member 100 can move axially along the first pipeline 600 under the condition that the fastening member unlocks the first clamping member, so as to adjust the value of the first deflection, thereby effectively adjusting the rigidity characteristic of the vibration isolation assembly, widening the frequency band range and improving the low-frequency isolation performance. It will be appreciated that first clamp 100 may also be connected to first conduit 600 in other ways, such as glued, etc.
Further, it should be noted that the elastic member 200 can be connected to the first pipeline 600 and the second pipeline 700 by means of glue. In the related art, since the first pipeline 600 and the second pipeline 700 are separately provided with pipeline clamps, a sufficient amount of clearance is required to be left between the two parallel pipelines for pipeline installation, and modular integration cannot be achieved. In the technical scheme of the present invention, since the elastic member 200 is disposed in the radial space between the first pipeline 600 and the second pipeline 700, local resonance caused by contact between the first pipeline 600 and the second pipeline 700 can be avoided, squeaking can be avoided, the pipeline system can be modularly integrated, the utilization rate of the pipe can be improved, the number of bending times can be reduced, the pipeline material can be reduced, the pipeline routing space can be reduced, the pipeline design difficulty and design cost can be reduced, and the reliability of the pipeline system can be improved.
Further, it should be noted that the first pressing rod 300 may be connected to the first clamping member 100 and the elastic member 200 respectively by a clamping connection, a threaded connection, or the like.
Further, it should be noted that the first pressing rod 300 is an elongated structure with a generally circular cross section, and has good buckling deformation performance. While the resilient member 200 is typically made of rubber, in some embodiments, other resilient materials may be used.
As an alternative to the above-described embodiment, as shown in fig. 2 and 4, the first clamping member 100 includes a first elastic base 100a, an intermediate elastic base 100b, a second elastic base 100c, a locking base 100d, and a locking member 100e. A first elastic base body 100a, the first elastic base body 100a being configured with a first receiving groove Sa, the first pipeline 600 being circumferentially fixed by the first receiving groove Sa. Generally, the first receiving groove Sa is adapted to the first pipeline 600, and the first receiving groove Sa circumferentially keeps the first pipeline 600 fixed. One end of the middle elastic base body 100b is connected to the first elastic base body 100a, and is configured with a first yielding channel Sb communicated with the first accommodating groove Sa; when being installed, the first pipeline 600 firstly passes through the first abdicating channel Sb and then is embedded into the first accommodating groove Sa. One end of the second elastic base body 100c is connected to one end of the middle elastic base body 100b away from the middle elastic base body 100b, and is configured with a second accommodating groove Sc communicated with the first abdicating channel Sb, and the first pressing rod 300 is circumferentially fixed by the second accommodating groove Sc; generally speaking, the second receiving groove Sc is adapted to the first pressing rod 300, and the first pressing rod 300 circumferentially keeps the second receiving groove Sc circumferentially fixed. When the installation, based on the deformation of elastic piece 200, first pipeline 600 loops through second holding tank Sc, first lane Sb of stepping down, imbeds in first holding tank Sa afterwards. In some alternative installation manners, for example, the first accommodating groove Sa is directly sleeved on the outer wall of the first pipeline 600 by an axial installation manner. One end of the locking base 100d is connected to one end of the second elastic base 100c away from the middle elastic base 100b, and a second avoiding channel Sd connected to the second receiving groove Sc is formed; a fixing hole 100f is formed in the locking base 100d, and an axial direction of the fixing hole 100f intersects with an extending direction of the second receding channel Sd; a locking member 100e, the locking member 100e being connected to the fixing hole 100 f. When being installed, the first pressing rod 300 is then inserted into the second receiving groove Sc through the second abdicating channel Sd. Since the locking base 100d is formed with the fixing hole 100f, the locking piece 100e is connected to the fixing hole 100f, so that the first clamping member 100 can be fixed to the first pipeline 600, and the first pressing rod 300 can be fixed to the first clamping member 100.
Generally, the second receiving groove Sc and the first pressing rod 300 are in interference fit. After the connection between the locking member 100e and the fixing hole 100f is released, the first accommodating groove Sa is in clearance fit with the first pipeline 600, and at this time, the first deflection of the first pressing rod 300 can be adjusted by adjusting the axial position of the first clamping member 100 on the first pipeline 600, so as to adjust the stiffness value. After being adjusted to the proper position, locking member 100e is coupled to the fixing member, and first clamping member 100 remains fixed to first conduit 600 based on the coordinated deformation of first clamping member 100.
In general, at least the first elastic base 100a may be made of rubber or metal rubber. The second elastic base 100c is made of metal spring-like metal wire and rubber by pressing, and in addition, in order to facilitate the first clamping member 100 to be integrally formed, the first elastic base 100a, the intermediate elastic base 100b, the second elastic base 100c, and the locking base 100d may be made of rubber or metal rubber. The elastic base body can be prevented from being damaged by high temperature and corrosion of the environment to cause failure, part of low-frequency noise can be absorbed, the acceleration amplitude of vibration excitation can be reduced, and the buffer effect is achieved.
As an alternative to the above embodiment, as shown in fig. 2, the first clamping member 100 further includes: the elastic film 100g is arranged on the inner wall of the first accommodating groove Sa, and one side, deviating from the inner wall of the first accommodating groove Sa, of the elastic film 100g is attached to the first pipeline 600. In general, the elastic film 100g is an ultra-thin metal composite film. Through set up elastic film 100g in first holding tank Sa, have the cushioning effect, can absorb the high-frequency vibration of first pipeline 600, and reduce pipeline acceleration amplitude for the vibration isolation subassembly carries out first order noise filtration, can filter high-frequency vibration and partly low frequency vibration basically. When the vibration excitation through elastic membrane 100g passes through the elastic matrix, the elasticity is specifically because the pretension effect of first depression bar 300, can filter some low frequency noise, and has further reduces acceleration amplitude under the cushioning effect.
As an alternative to the above embodiment, referring to fig. 3, 5 and 6, the vibration isolation assembly further includes: a second clamp 400, wherein the second clamp 400 is connected with the second pipeline 700; the second clamping member 400 and the first clamping member 100 are respectively positioned at two sides of the elastic member 200; and a second pressing rod 500, wherein one end of the second pressing rod 500 is connected with the second clamping member 400, the other end of the second pressing rod 500 is connected with the elastic member 200, and the second pressing rod 500 is in a bending state.
The second plunger 500 is put in flexion by applying pressure thereto.
Since the second pressing rod 500 is in a bending state and the elastic member 200 has nonlinearity, when low-frequency vibration occurs in the second pipeline 700, at least a part of the excitation of the low-frequency vibration is absorbed by the vibration isolation assembly, and the transmission of low-frequency noise to the air conditioner is reduced. It should be noted that, in general, the maximum deflection value of the second pressing rod 500 in the bending state is the deflection value of the second pressing rod 500 in the quasi-zero stiffness range, so that the vibration isolation assembly can reach the quasi-zero state and can resist low-frequency vibration. The value of the second deflection can be obtained by a finite element method and an experimental method. Typically, the second deflection is related to the axial length of the second strut 500, the stiffness of the resilient member 200, and the radial spacing of the first and second conduits 600, 700. The inventors' studies in conjunction with the present invention have found that the maximum deflection value is generally between 1 and 3 mm.
In the preferred embodiment, the first pressure lever 300 and the second pressure lever 500 are supported by the same elastic member 200 to form a non-linear vibration isolation system capable of improving the effect of absorbing low-frequency noise, and together absorb low-frequency vibration of the parallel pipelines.
It should be noted that the structure of the second clamping member 400 is identical to that of the first clamping member 100. The second pressing lever 500 has the same structure as the first pressing lever 300. The connection structure of the second pressing rod 500 and the second clamping member 400 is referred to the connection structure of the first pressing rod 300 and the first clamping member 100. The connection structure of the second pressing rod 500 and the elastic member 200 refers to the connection structure of the second pressing rod 500 and the elastic member 200.
In the related art, since the pipe clamp is disposed on the first pipe 600 and the second pipe 700, the first pipe 600 and the second pipe 700 operate under the same stiffness condition, and resonance is easily generated. In a preferred embodiment of the present invention, the maximum deflection value (first deflection) of the first pressing rod 300 is not equal to the maximum deflection value (second deflection) of the second pressing rod 500. Different values of the first deflection can make the stiffness of the first pipeline 600 different; different values of the second deflection can cause the second pipeline 700 to have different stiffness. When the first deflection and the second deflection take different values, the rigidity of the first pipeline 600 and the second pipeline 700 is different, so that the two pipelines connected in parallel in a coupling mode run under the working conditions with different rigidities, the first pipeline 600 and the second pipeline 700 can be prevented from vibrating at the same frequency, and resonance can be avoided. Therefore, the technical problem of low-frequency noise of the pipeline can be effectively solved, the first deflection is not equal to the second deflection, the rigidity of the pipeline is different, and the resonance problem caused by pipeline interference is avoided.
As an alternative to the above embodiment, as shown in fig. 7, the elastic member 200 includes: the first base surface 200b and the second base surface 200a are oppositely arranged, the first base surface 200b is attached to the first pipeline 600, and the second base surface 200a is attached to the second pipeline 700; a first accommodating hole 200c, the first accommodating hole 200c being disposed close to the second base 200a, the first pressing rod 300 being embedded in the first accommodating hole 200c and being tightly fitted with the first accommodating hole 200 c; and a second receiving hole 200d, the second receiving hole 200d is disposed close to the first base 200b, and the second pressing rod 500 is inserted into the second receiving hole 200d and tightly fitted with the second receiving hole 200 d.
When the elastic member 200 is disposed between the first pipe 600 and the second pipe 700, the first base surface 200b and the second base surface 200a are disposed to be spaced apart from each other in the radial direction of the pipes. First base plane 200b is the arc surface with first pipeline 600 mutual adaptation, and a part outer wall and the laminating of first base plane 200b of first pipeline 600. The second base 200a is a circular arc surface matched with the second pipeline 700, and a part of the outer wall of the second pipeline 700 is attached to the second base 200 a. Generally, the elastic member 200 may be adhered to the first and second pipes 600 and 700 by means of adhesive bonding.
In the technical solution of the present embodiment, the first accommodating hole 200c is close to the second base surface 200a, and the first pressing rod 300 is inserted into the first accommodating hole 200c to fixedly connect the first pressing rod 300 and the elastic member 200. Since the first accommodating hole 200c is close to the second base 200a, that is, the other end of the first pressing rod 300 is closer to the second pipeline 700 than the first pipeline 600, at this time, the adjustable range of the first deflection of the first pressing rod 300 in the quasi-zero stiffness range is wider, the frequency band range is widened, and the low-frequency that can be adapted to is wider. Similarly, since the second receiving hole 200d is close to the first base 200b, that is, the other end of the second pressure lever 500 is closer to the first pipeline 600 than the second pipeline 700, the adjustable range of the first deflection of the second pressure lever 500 within the quasi-zero stiffness range is wider, the frequency band range is widened, and the low frequency that can be adapted to is wider. Thus, the vibration isolation assembly can absorb low-frequency vibration in a wider frequency range.
As an alternative embodiment of the above embodiment, the first receiving hole 200c has a first protrusion 200c-1 protruding into the hole of the first receiving hole 200c, and the first pressing rod 300 is closely attached to the first protrusion 200 c-1; the second receiving hole 200d has a second protrusion 200d-1 protruding into the hole of the second receiving hole 200d, and the second pressing rod 500 is tightly abutted to the second protrusion 200 d-1. After the first pressing rod 300 is inserted into the first accommodating cavity, the first protrusion 200c-1 deforms due to the elasticity of the elastic member 200 to fasten the first pressing rod 300 in the hole of the first accommodating cavity 200c, and at this time, the first protrusion 200c-1 is tightly attached to the first pressing rod 300, so that the first pressing rod 300 is fixedly connected to the elastic member 200. Similarly, after the second pressing rod 500 is inserted into the second accommodating hole, due to the elasticity of the elastic member 200, the second protrusion 200d-1 deforms to fasten the second pressing rod 500 in the hole of the second accommodating hole 200d, and at this time, the second protrusion 200d-1 is tightly attached to the second pressing rod 500, so that the second pressing rod 500 is fixedly connected to the second accommodating hole 200 d.
As an alternative to the above embodiment, the elastic member 200 further includes: a cavity 200e, the first base 200b and the second base 200a being symmetrically arranged about a centerline of the cavity 200e; the first and second receiving holes 200c and 200d are symmetrically arranged about a center line of the cavity 200 e. Generally, the cavity 200e is located in the central region of the elastic element 200, the cavity 200e enables the elastic element 200 to have sufficient deformation displacement, and when the elastic element 200 absorbs vibration, the solid region of the elastic element 200 can slightly displace towards the cavity 200e, so as to improve the deformation capability of the elastic element 200. The cross-sectional shape of the cavity 200e is similar to the outer shape of the elastic member 200, and may be configured to be rectangular, for example.
