Description

Technical Field

[0001] This application relates to the field of vibration reduction technology, such as a control method, control device, air conditioner, and storage medium for vibration reduction devices. Background Technology

[0002] The compressor is the core vibration source of an air conditioner. The compressor vibrates during operation, which in turn worsens the air conditioner's vibration and noise levels. Especially when the compressor operates near its modal frequency, resonance occurs, resulting in very large vibration amplitudes that can seriously lead to air conditioner pipe rupture and failure.

[0003] A vibration damping assembly for a compressor is disclosed in related technology for fixing the compressor to a frame. The compressor includes a foot with a first mounting hole. The vibration damping assembly includes a bolt assembly with a bolt and a nut. The vibration damping assembly also includes a base, a buffer cover, and a foot pad coaxially arranged on the bolt from bottom to top. One end of the base is fixedly connected to the frame, and the other end of the base is slidably engaged with the lower end of the buffer cover. A first vibration damping pad is sandwiched between the base and the buffer cover. The foot pad is engaged in the first mounting hole. The base, the first vibration damping pad, the buffer cover, and the foot pad form interconnected bolt holes. The nut of the bolt abuts against the frame, and the stud of the bolt passes sequentially through the bolt holes of the base, the first vibration damping pad, the buffer cover, and the foot pad, and is connected to the nut, thereby fixing the compressor to the frame.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The vibration reduction effect of the vibration damping components is fixed and limited.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a control method, control device, air conditioner, and storage medium for a vibration damping device to improve the vibration damping effect on a compressor.

[0009] In some embodiments, the control method for the vibration damping device includes a double-layered structure capable of being retracted or extended; the stiffness of the vibration damping device differs depending on whether it is in a retracted or extended state; the method includes: acquiring the operating frequency of the compressor; determining a target state of the vibration damping device based on the operating frequency of the compressor; and controlling the operation of the vibration damping device based on the target state.

[0010] In some embodiments, the control device for the vibration damping device includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned control method for the vibration damping device when the program instructions are executed.

[0011] In some embodiments, the air conditioner includes: a housing; a vibration damping device disposed within the housing; a compressor disposed within the housing and mounted on the vibration damping device; and a control device for the vibration damping device as described above, mounted within the housing.

[0012] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned control method for the vibration damping device.

[0013] The control method, control device, air conditioner, and storage medium for vibration damping devices provided in this disclosure can achieve the following technical effects:

[0014] First, based on the compressor's operating frequency, it is determined whether the compressor is prone to resonance. Then, the target state of the vibration damping device is determined—whether it should be in a retracted or deployed state. Finally, the vibration damping device is controlled to operate in the target state to change its stiffness, thereby altering the compressor's modal frequency. This prevents compressor resonance and improves the vibration damping effect of the device.

[0046] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a vibration damping device 1 for a compressor, including: a support portion 10 and a retractable assembly 20. The support portion 10 is used to connect to the compressor 3 to provide support for the compressor 3. The retractable assembly 20 is disposed outside the support portion 10 and can be retracted or extended with the support portion 10 as the retractable center. See also Figure 1 When the retractable assembly 20 is subjected to external force, it moves towards the support portion 10, thus retracting and providing support to the compressor 3 together with the support portion 10. See also Figure 2 When the retractable assembly 20 is not subjected to external force, it moves away from the support portion 10 and unfolds, thereby allowing the support portion 10 to provide support force to the compressor 3 independently. Optionally, the retractable assembly 20 is retracted or unfolded based on the vibration frequency of the compressor 3 to provide different support forces to the compressor 3, thereby achieving different vibration reduction effects.

[0047] The vibration damping device 1 for a compressor provided in this embodiment has a retractable assembly 20 disposed outside the support portion 10, which can be retracted under external force or extended when no external force is applied. When the retractable assembly 20 is extended, only the support portion 10 supports the compressor 3. At this time, the overall stiffness of the vibration damping device 1 is relatively small, and the vibration damping effect is small. When the retractable assembly 20 is retracted, it supports the compressor 3 together with the support portion 10. At this time, the overall stiffness of the vibration damping device 1 increases, and the vibration damping effect is also greater. In this way, by retracting and extending the retractable assembly 20, the overall stiffness of the vibration damping device 1 is changed, thereby allowing the support force on the compressor 3 to be adjusted based on the actual operating conditions of the compressor 3. Thus, the vibration damping effect of the vibration damping device 1 can be matched with the operating state of the compressor 3, thereby improving the vibration damping effect on the compressor 3.

[0048] Optionally, when the retractable assembly 20 is deployed, the overall stiffness of the vibration damping device 1 is K1. When the retractable assembly 20 is retracted, the overall stiffness of the vibration damping device 1 is K2. Wherein, K2>K1. Optionally, K2≥2*K1.

[0049] Optionally, combined Figure 3 and Figure 4As shown, the support part 10 has a cylindrical structure.

[0050] Optionally, combined Figure 5 As shown, the outer wall of the support portion 10 has a mounting groove 11 that is recessed into the support portion 10. The base 2 of the compressor 3 can be installed in the mounting groove 11.

[0051] Optionally, the mounting groove 11 is an annular groove formed on the outer periphery of the support portion 10. Optionally, a mounting hole is formed on the base 2 of the compressor 3. The support portion 10 passes through the mounting hole, and the base 2 is engaged within the annular groove, thereby supporting the compressor 3. The annular groove and the mounting hole are either interference-fitted or clearance-fitted.

[0052] See you again Figure 5 The portion of the support 10 located above the mounting groove 11 is equivalent to the guide 12, which guides the base 2 to be installed on the vibration damping device 1 and guides the vibration damping device 1 to detach from the base 2.

[0053] Optionally, a transition surface 13, which is inclined or arc-shaped, is provided between the top wall and the outer wall of the support portion 10. That is, the outer wall of the guide portion 12 is the transition surface 13.

[0054] Optionally, the transition surface 13 is located above the mounting groove 11. The transition surface 13 causes the diameter of the guide portion 12 to gradually decrease from bottom to top. In this way, the top of the support portion 10 can more easily enter the mounting hole of the base 2, thereby facilitating the installation and removal of the compressor 3.

[0055] Optionally, the support portion 10 is made of EPDM or nitrile rubber. This makes the guide portion 12 more easily deformable, thus making it easier for the support portion 10 to pass through the mounting hole in the base 2. During the process of the support portion 10 passing through the mounting hole, the guide portion 12 is deformed by the pressure of the mounting hole. When the mounting hole is within the mounting groove 11, the shape of the guide portion 12 is completely or slightly restored.

[0056] Optionally, the diameter of the bottom of the guide portion 12, that is, the diameter D1 of the upper wall 111 used to form the annular mounting groove, is smaller than the diameter D2 of the lower wall 112 used to form the annular mounting groove.

[0057] Optionally, combined Figure 6 As shown, an annular groove 14 is provided on the upper wall 111 of the annular mounting groove. In this way, when the base 2 of the compressor 3 is installed from top to bottom, the annular groove 14 makes it easier for the guide part 12 to deform and shrink inward, so as to facilitate installation.

[0058] Optionally, see again Figure 5The support part 10 has a central hole 15 extending through both ends of its axial direction, and the central hole 15 is coaxial with the support part 10. The central hole 15 is used to cooperate with fastening structures such as bolts or screws to fix the vibration damping device 1 to the air conditioner.

[0059] Optionally, see again Figure 1 and Figure 2 The retractable assembly 20 includes an elastic retractable layer 21. The elastic retractable layer 21 is arranged around the outer periphery of the support portion 10, and its inner sidewall near its bottom is connected to the outer sidewall near its bottom of the support portion 10. The lower wall 112, which forms the annular mounting groove, serves as the support surface for the support portion 10 to support the compressor 3. When the elastic retractable layer 21 is subjected to external force, it deforms and gathers around the support portion 10. At this time, the top of the elastic retractable layer 21 is flush with the support surface of the support portion 10. The elastic retractable layer 21 and the support portion 10 together provide support for the compressor 3. When the elastic retractable layer 21 is not subjected to external force, it returns to its original shape and unfolds. At this time, the top of the elastic retractable layer 21 is lower than the support surface of the support portion 10, and only the support portion 10 provides support for the compressor 3. Thus, by utilizing the difference in height of the top of the elastic retractable layer 21 when it is retracted and unfolded, it is possible to achieve either joint support with the support portion 10 or support portion 10 providing support alone.

[0060] Optionally, the elastic stretching layer 21 is made of EPDM or nitrile rubber.

[0061] Optionally, see Figure 2 , Figure 3 , Figure 7 and Figure 8 The retractable assembly 20 also includes an elastic support portion 22. The elastic support portion 22 is disposed between the support portion 10 and the elastic retractable layer 21. Simultaneously, the elastic support portion 22 contacts the outer sidewall of the support portion 10 and the inner sidewall of the elastic retractable layer 21. When the elastic retractable layer 21 is subjected to an external force, the elastic support portion 22 is compressed. When the elastic retractable layer 21 is not subjected to an external force, the shape of the elastic support portion 22 returns to its original state, thereby providing an external force to the elastic retractable layer 21 to help it unfold. In this way, the elastic support portion 22 can provide an unfolding force to the elastic retractable layer 21 to ensure that the elastic retractable assembly 20 is fully unfolded.

[0062] Optionally, see Figure 2 and Figure 3 There are two elastic support parts 22, which are arranged opposite each other and are an integral structure with the elastic retractable layer 21.

[0063] Optionally, see Figure 7 and Figure 8 The elastic support part 22 is an independent structure in the shape of a ring and is sleeved on the outer periphery of the support part 10.

[0064] Optionally, see again Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10 The vibration damping device 1 also includes a drive mechanism 30. The drive mechanism 30 is connected to the retractable assembly 20. Specifically, the drive mechanism 30 is connected to the elastic retractable layer 21 to provide external force to the retractable assembly 20, thereby driving the retractable assembly 20 to retract.

[0065] Optionally, see again Figure 1 , Figure 2 and Figure 7 The drive mechanism 30 includes a first drive component 31. The first drive component 31 is connected to the outer wall of the elastic retractable layer 21 of the retractable component 20. When the drive mechanism 30 is energized, it can drive the elastic retractable layer 21 to retract.

[0066] Optionally, the first drive component 31 is positioned close to the top of the retractable component 20, that is, close to the top of the elastic retractable layer 21. Since the top of the elastic retractable layer 21 is the position with the largest degree of expansion, positioning the first drive component 31 close to the top of the elastic retractable layer 21 allows for the application of a larger external force to the top. In this way, it can be ensured that the elastic retractable layer 21 is retracted to the maximum extent.

[0067] Optionally, see Figure 9 and Figure 10 The first driving component 31 includes a first magnetic clamping part 311 and a second magnetic clamping part 312. Both are disposed on the outer side wall of the retractable component 20 and are arranged opposite to each other. When the first magnetic clamping part 311 is energized, the first magnetic clamping part 311 and the second magnetic clamping part 312 are attracted together. At this time, due to the attraction of the first magnetic clamping part 311 and the second magnetic clamping part 312, an external force is generated on the retractable component 20, causing the retractable component 20 to retract. When the first magnetic clamping part 311 is not energized, the first magnetic clamping part 311 and the second magnetic clamping part 312 cannot be attracted together. At this time, because the first magnetic clamping part 311 and the second magnetic clamping part 312 are separated, they cannot apply external force to the retractable component 20, thereby causing the retractable component 20 to unfold.

[0068] Optionally, the first magnetic clamping part 311 includes: a first connecting plate 3111, a first electromagnetic switch 3112, and two first suction ears 3113. The first connecting plate 3111 is connected to the outer wall of the retractable assembly 20, that is, to the outer wall of the elastic retractable layer 21. The two first suction ears 3113 are respectively disposed on the two vertical sides of the first connecting plate 3111. The first electromagnetic switch 3112 is disposed on one of the first suction ears 3113.

[0069] Optionally, the second magnetic clamping part 312 includes a second connecting plate 3121 and two second suction ears 3122. The second connecting plate 3121 is connected to the outer wall of the retractable assembly 20, that is, to the outer wall of the elastic retractable layer 21. The two second suction ears 3122 are respectively disposed on the two vertical sides of the second connecting plate 3121. The two first suction ears 3113 correspond one-to-one with the two second suction ears 3122.

[0070] By controlling the first electromagnetic switch 3112 to be energized and generate a magnetic field, the corresponding second latch 3122 is attracted to each other. Furthermore, by controlling the first electromagnetic switch 3112 to be closed, there is no attraction between the corresponding second latches 3122.

[0071] Optionally, the second suction ear 3122 is made of magnetic metal.

[0072] Optionally, see [link to relevant documentation] Figure 9 and Figure 10 The first magnetic clamping part 311 also includes a second electromagnetic switch 3114. The second electromagnetic switch 3114 is disposed on another first attraction ear 3113. The first electromagnetic switch 3112 and the second electromagnetic switch 3114 can be energized simultaneously, thereby attracting both second attraction ears 3122 at the same time, making the attraction process more stable and the attraction force greater.

[0073] Optionally, to match the arc shape of the outer side wall of the elastic retractable layer 21, both the first connecting plate 3111 and the second connecting plate 3121 are arc-shaped.

[0074] Optionally, the drive mechanism 30 further includes a power supply. The power supply is electrically connected to the first drive assembly 31. The power supply is capable of supplying power to the first drive assembly 31. Specifically, the power supply is electrically connected to the first electromagnetic switch 3112 and the second electromagnetic switch 3114 to supply power to the two electromagnetic switches, thereby causing the first magnetic clamping part 311 and the second magnetic clamping part 312 to attract each other.

[0075] Optionally, combined Figure 11 and Figure 12 As shown, the drive mechanism 30 further includes a second drive component 32. The second drive component 32 is disposed on the outer wall of the retractable component 20, that is, connected to the outer wall of the elastic retractable layer 21. The height of the second drive component 32 is lower than the height of the first drive component 31. In this way, the first drive component 31 and the second drive component 32 can be controlled to be powered on and off simultaneously, or powered on and off in a set sequence. Thus, the second drive component 32 can work in conjunction with the first drive component 31 to drive the retractable component 20 to retract.

[0076] Optionally, the specific structure of the second drive component 32 is the same as that of the first drive component 31, and will not be described in detail here.

[0077] Optionally, the second drive assembly 32 is correspondingly disposed with the elastic support portion 22. This is because the elastic support portion 22 can provide an unfolding force for the elastic retractable layer 21, but when driving the elastic retractable layer 21 to retract, the elastic support portion 22 will hinder the retraction of the elastic retractable layer 21. Since the second drive assembly 32 is disposed corresponding to the elastic support portion 22, the driving force of the second drive assembly 32 can precisely resist the elastic force of the elastic support portion 22, thus making it easier for the retractable assembly 20 to retract.

[0078] Optionally, if the elastic support force applied by the elastic support part 22 to the elastic retractable layer 21 is set to F1, and the external force applied by the first drive component 31 or the second drive component 32 to the elastic retractable layer 21 is F2 (that is, the attraction force of the corresponding two magnetic clamping parts is F2), then F2>F1.

[0079] Optionally, the power supply is electrically connected to the second drive component 32, thereby supplying power to the second drive component 32.

[0080] Combination Figure 13 As shown, this embodiment of the present disclosure provides an air conditioner, including: a chassis and the aforementioned vibration damping device 1 for the compressor. The vibration damping device 1 is fixed to the chassis by bolts, screws, or other fastening structures.

[0081] Optionally, the air conditioner also includes a compressor 3 and a base 2. The base 2 of the compressor 3 is installed in the mounting slot 11.

[0082] Combination Figure 14 As shown, this disclosure provides a control method for a vibration damping device, including:

[0083] S1401, the air conditioner obtains the operating frequency of the compressor.

[0084] S1402, the air conditioner determines the target state of the vibration damping device based on the operating frequency of the compressor.

[0085] S1403, the air conditioner controls the operation of the vibration damping device according to the target state.

[0086] The compressor vibrates when it is running. If the compressor's operating frequency is close to the preset modal frequency, resonance will occur, which will cause the air conditioner to make noise.

[0087] Based on the above, firstly, when the compressor is running, its operating frequency is obtained. Based on the compressor's operating frequency, the target state of the vibration damping device is determined. The target state is either a retracted state or an extended state. Optionally, the closer the compressor's operating frequency is to a preset modal frequency, the greater the possibility of resonance. Therefore, the vibration damping device needs to have greater stiffness to improve its vibration damping effect on the compressor. Finally, based on the target state, the vibration damping device is controlled to operate in either the retracted or extended state.

[0088] The control method for vibration damping devices provided in this disclosure first determines whether the compressor is prone to resonance based on its operating frequency, and then determines the target state of the vibration damping device, i.e., whether the vibration damping device needs to be in a retracted or extended state. Finally, the vibration damping device is controlled to operate to the target state to change its stiffness, thereby changing the modal frequency of the compressor. In this way, compressor resonance can be avoided, and the vibration damping effect of the vibration damping device on the compressor can be improved.

[0089] Optionally, combined Figure 15 As shown, this disclosure provides another control method for a vibration damping device, including:

[0090] S1401, the air conditioner obtains the operating frequency of the compressor.

[0091] S1412, the frequency difference between the air conditioner's calculated operating frequency and the preset mode frequency.

[0092] S1422, the air conditioner determines the target state of the vibration damping device based on the frequency difference.

[0093] S1403, the air conditioner controls the operation of the vibration damping device according to the target state.

[0094] Calculate the frequency difference Δf according to formula (1):

[0095] Δf=f-f0 Formula (1)

[0096] Where f is the operating frequency of the compressor, and f0 is the preset modal frequency of the compressor.

[0097] The frequency difference can characterize whether the compressor's operating frequency is close to the preset modal frequency, thereby determining whether the stiffness of the vibration damping device needs to be increased. In this way, the target state of the vibration damping device can be determined based on the frequency difference, so that the vibration damping device can prevent the compressor from resonating when it is in the target state.

[0098] Optionally, the preset modal frequencies are: the first 6 modal frequencies of the compressor when the vibration damping device is in the deployed state to support the compressor (when only the support part supports the compressor).

[0099] Optionally, in step S1422, the air conditioner determines the target state of the vibration damping device based on the frequency difference, including:

[0100] When the frequency difference is within the preset frequency range, the air conditioner determines the target state of the vibration damping device as the retracted state.

[0101] When the frequency difference is outside the preset frequency range, the air conditioner determines the target state of the vibration damping device as the deployed state.

[0102] The air conditioner's processor stores a preset frequency range. If the frequency difference is within the preset range, it indicates that the compressor's operating frequency is close to the preset modal frequency. In this case, the compressor is prone to resonance, thus determining the target state for the vibration damping device as the retracted state. If the frequency difference is outside the preset range, it indicates that the compressor's operating frequency differs significantly from the modal frequency. In this case, the compressor is less likely to resonate, thus determining the target state for the vibration damping device as the deployed state. Therefore, by using the preset frequency range as a benchmark, it's possible to determine whether the compressor's operating frequency is close to the preset modal frequency. This allows for a more accurate assessment of whether the compressor is prone to resonance, enabling timely adjustment of the vibration damping device's stiffness to improve its vibration reduction effect on the compressor.

[0103] Optionally, the preset frequency range is [-A, A], where A is 3Hz.

[0104] Optionally, the preset frequency range is [-kf0, kf0], where k is a proportionality coefficient, which can be 10%.

[0105] Optionally, combined Figure 16 As shown, this disclosure provides a control method for a vibration damping device, including:

[0106] S1401, the air conditioner obtains the operating frequency of the compressor.

[0107] S1402, the air conditioner determines the target state of the vibration damping device based on the operating frequency of the compressor.

[0108] S1413, when the air conditioner is in the retracted state, it controls the retractable component to be subjected to external force, thereby controlling the retractable component to retract, so as to support the compressor together with the support unit.

[0109] S1423, when the air conditioner is in the deployed state, it controls the retractable assembly to be free from external force, thereby controlling the retractable assembly to deploy so that the support part supports the compressor.

[0110] As described above regarding the structure of the vibration damping device, its retraction is achieved by applying an external force to the outer retraction assembly. Therefore, if the target state is the retracted state, the retraction assembly is controlled to be subjected to an external force. Thus, the retraction assembly retracts under the action of this external force. When the retraction assembly is fully retracted, its top is flush with the support surface of the support unit, thereby supporting the compressor together with the support unit. At this point, the stiffness K2 of the vibration damping device is achieved.

[0111] If the target state is the unfolded state, the retractable assembly is controlled to be free from external forces. Thus, the retractable assembly unfolds under the elasticity of the elastic retractable layer and the elastic support force of the elastic support section. When the retractable assembly is fully unfolded, the top of the retractable assembly is lower than the support surface of the support section, meaning only the support section supports the compressor. At this point, the stiffness of the vibration damping device is K1.

[0112] Optionally, K2 ≥ 2*K1. Thus, when the compressor's operating frequency approaches the preset modal frequency, controlling the retraction of the retractable assembly can increase the stiffness of the vibration damping device by two times or more. This also increases the compressor's modal frequency by two times or more, resulting in a significant difference between the compressor's operating frequency and the modal frequency, thereby preventing compressor resonance.

[0113] Optionally, in step S1413, the air conditioning control retraction component is subjected to an external force, including:

[0114] When the air conditioner controls the first magnetic clamping part to be energized, it generates a magnetic field, which in turn attracts the second magnetic clamping part.

[0115] As described above regarding the structure of the vibration damping device, the outer wall of the elastic retractable layer is provided with corresponding first and second magnetic clamping parts. When the first magnetic clamping part is energized, it generates a magnetic field, which then attracts the second magnetic clamping part. The attraction force is an external force applied to the elastic retractable layer, thereby achieving the retraction of the elastic retractable layer. Optionally, by controlling the first electromagnetic switch to be energized, it generates a magnetic field, which then attracts the corresponding second suction ear, which is made of magnetic metal. Optionally, by controlling both the first and second electromagnetic switches to be energized, both electromagnetic switches generate magnetic fields, which then attract the corresponding second suction ears respectively. Thus, by utilizing the magnetic field generated by the energized first electromagnetic switch and the fact that the second suction ear is made of magnetic metal, the first and second magnetic clamping parts are mutually attracted.

[0116] Optionally, in step S1423, the air conditioning control retraction assembly is not subject to external force, including:

[0117] The air conditioner controls the first magnetic clamping part to lose power, so that the first magnetic clamping part does not generate a magnetic field, and thus separates from the second magnetic clamping part.

[0118] As can be seen from the structure of the vibration damping device described above, the outer wall of the elastic retractable layer is provided with corresponding first magnetic clamping parts and second magnetic clamping parts. By de-energizing the first magnetic clamping part, it can prevent the generation of a magnetic field, thus preventing it from engaging with the second magnetic clamping part. In this way, without the attraction force, no external force is applied to the elastic retractable layer, thereby enabling its unfolding. Optionally, by controlling the first electromagnetic switch to de-energize, it prevents the generation of a magnetic field, thus preventing it from engaging with its corresponding second suction ear, which is made of magnetic metal. Optionally, by controlling both the first and second electromagnetic switches to de-energize, neither electromagnetic switch generates a magnetic field, thus preventing them from engaging with their corresponding second suction ears. In this way, by utilizing the fact that the first electromagnetic switch is de-energized and does not generate a magnetic field, and that the second suction ear is made of magnetic metal, the first magnetic clamping part and the second magnetic clamping part can be separated.

[0119] Optionally, in step S1413, the air conditioning control retraction assembly is retracted, including:

[0120] The air conditioning control system simultaneously drives the retractable assembly to retract; or...

[0121] The air conditioner first controls the second drive component to retract the retractable component, and then controls the first drive component to retract the retractable component.

[0122] As can be seen from the structure of the vibration damping device described above, a first drive component and a second drive component are respectively installed at different height positions on the outside of the retractable component, and the position of the second drive component is lower than that of the first drive component.

[0123] Optionally, the first and second drive components can be controlled to simultaneously drive the retracting component to retract, that is, the two magnetic clamping parts of the first drive component can be controlled to engage, and the two magnetic clamping parts of the second drive component can be controlled to engage simultaneously. In this way, the retracting component can be retracted at different height positions at the same time, so as to improve the retraction efficiency and avoid compressor resonance in time.

[0124] Optionally, since the elastic support portion applies an elastic supporting force to the elastic retractable layer, the position of the elastic retractable layer corresponding to the elastic support portion is relatively more difficult to retract. Therefore, the second drive assembly is first controlled to drive the retractable assembly to retract, so that the external force applied by the second drive assembly to the elastic retractable layer resists the elastic supporting force applied by the elastic support portion. After the two magnetic clamping portions of the second drive assembly are engaged, the two magnetic clamping portions of the first drive assembly are then controlled to engage. In this way, the elastic retractable layer can be retracted more easily.

[0125] Combination Figure 17As shown, this embodiment of the disclosure provides a control device 170 for a vibration damping device, including: an acquisition module 171, a determination module 172, and a control module 173.

The control module 173 is configured to control the operation of the vibration damping device based on the target state.

[0126] The control device for the vibration damping device provided in this embodiment first determines whether the compressor is prone to resonance based on its operating frequency, and then determines the target state of the vibration damping device, i.e., whether the vibration damping device needs to be in a retracted or extended state. Finally, the vibration damping device is controlled to operate to the target state to change its stiffness, thereby changing the modal frequency of the compressor. In this way, compressor resonance can be avoided, and the vibration damping effect of the vibration damping device on the compressor can be improved.
