Description

Technical Field

[0001] This application relates to the field of home appliance technology, such as a vibration isolation device, a control method for the vibration isolation device, and a storage medium. Background Technology

[0002] Currently, the compressor is the core component of an air conditioner. Its performance not only determines the air conditioner's energy efficiency rating but also directly affects its vibration and noise levels. With the rapid development of the home appliance industry towards green and low-carbon practices, low energy consumption has become a crucial direction for air conditioning technology development. This has led to a continuous reduction in the compressor's operating frequency, even covering multiple resonant frequencies of the compressor's vibration isolation system. Operating the compressor within this resonant frequency range results in severe vibration of the compressor and piping, making it difficult for the piping stress to meet fatigue design requirements.

[0003] Currently, improving the structure and material properties of the foot pads to reduce the resonant frequency of the vibration isolation system and increasing the damping of the foot pads are the main solutions. Replacing the foot pads with metal coil springs to reduce the resonant frequency is another solution. However, these methods cannot significantly reduce the resonant frequency of the vibration isolation system. Furthermore, increasing the damping of the foot pads leads to increased vibration transmitted to the casing during high-frequency operation of the press, resulting in increased radiated noise levels from the external casing.

[0004] It is evident that how to avoid resonance between the compressor and the vibration isolation device, reduce the vibration amplitude of the compressor, and reduce radiated noise has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] 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

[0006] 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.

[0007] This disclosure provides a vibration isolation device, a control method for the vibration isolation device, and a storage medium to address the technical problem that the resonant frequency of a vibration isolation system cannot be significantly reduced, and that increasing the damping of the foot pads leads to increased vibration transmitted to the casing during high-frequency operation of the press, resulting in increased radiated noise levels from the outer casing.

[0008] In some embodiments, the vibration isolation device includes: a boom, a support foot, an adjustable spring, a motion acquisition module, and a controller assembly. The lower end of the boom is fixedly connected to the compressor; the support foot is fixedly connected to the upper end of the boom; the adjustable spring is fixed to the boom and provides lateral support force; the motion acquisition module is used to acquire motion data of the compressor; the controller assembly is connected to both the motion acquisition module and the adjustable spring, and is used to control the stiffness of the adjustable spring based on the compressor motion data acquired by the motion acquisition module.

[0009] In some embodiments, the control method for the vibration isolation device includes:

[0010] Determine the compressor's motion data;

[0011] The stiffness of the adjustable spring is controlled based on the compressor's motion data.

[0012] In some embodiments, the storage medium stores program instructions that, when executed, perform the control method for the vibration isolation device according to any of the above embodiments.

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

[0014] By fixing the compressor to the bottom from above using a suspension rod, the traction force of the rod can achieve a good vibration damping effect. An adjustable spring on the suspension rod provides support for its lateral displacement, thus suppressing its vibration. During use, the vibration of the compressor is determined by a motion acquisition module, and the stiffness of the adjustable spring is adjusted accordingly. This alters the suppression effect on the suspension rod's vibration, changing its vibration frequency to create a difference between it and the compressor's vibration frequency, reducing the risk of resonance between the two. This prevents resonance between the vibration isolation device and the compressor from increasing amplitude, reducing radiated noise, and improving the user experience.

[0040] Combination Figure 1-7 As shown, this embodiment of the disclosure provides a vibration isolation device including: a suspension rod 200, a support foot 300, an adjustable spring 400, a motion acquisition module 500, and a controller assembly 600. The lower end of the suspension rod 200 is used to fixably connect to a compressor; the support foot 300 is fixedly connected to the upper end of the suspension rod 200; the adjustable spring 400 is fixed to the suspension rod 200 and provides lateral support force to the suspension rod 200; the motion acquisition module 500 is used to acquire motion data of the compressor; the controller assembly 600 is connected to both the motion acquisition module 500 and the adjustable spring 400, and is used to control the stiffness of the adjustable spring 400 according to the compressor motion data acquired by the motion acquisition module 500.

[0041] The vibration isolation device provided in this embodiment uses a suspension rod 200 to fix the bottom of the compressor from above. The traction force of the suspension rod 200 can achieve a good vibration reduction effect. An adjustable spring 400 is installed on the suspension rod 200 to support the lateral displacement of the suspension rod 200, thereby suppressing the vibration of the suspension rod 200. During use, the vibration of the compressor is determined by the motion acquisition module 500, and the stiffness of the adjustable spring 400 is adjusted to change its suppression effect on the vibration of the suspension rod 200. This changes the vibration frequency of the suspension rod 200, widening the gap between it and the vibration frequency of the compressor, reducing the risk of resonance between the two, avoiding resonance between the vibration isolation device and the compressor that would lead to increased amplitude, reducing radiated noise, and improving the user experience.

[0042] Optionally, the support foot 300 includes a longitudinal support portion 301 and a transverse connecting portion 302. The bottom of the longitudinal support portion 301 is installed at a height lower than the bottom of the compressor; the transverse connecting portion 302 is fixedly disposed at the upper end of the longitudinal support portion 301 and extends towards one side of the longitudinal support portion 301, wherein the hanger rod 200 is fixedly disposed on the lower end face of the transverse connecting portion 302. In this way, the bottom of the longitudinal support portion 301 is lower than the bottom of the compressor, allowing the bottom of the compressor to be suspended when it is fixed, making full use of the support foot 300 for shock absorption. Furthermore, the transverse connecting portion 302 is provided at the upper end of the longitudinal support portion 301 to fix the hanger rod 200 from the top. The entire compressor is hoisted by the hanger rod 200. Compared with supporting the compressor from the bottom, the hanger rod 200 can better buffer the vibration of the compressor, reduce the transmission of compressor vibration to the outer casing, and thus reduce the overall vibration.

[0043] Optionally, the longitudinal support 301 is parallel to the hanger rod 200, and the adjustable spring 400 is disposed between the longitudinal support 301 and the hanger rod 200. In this way, the longitudinal support 301 supports one end of the adjustable spring 400, and the adjustable spring 400 is positioned between the longitudinal support 301 and the hanger rod 200. The adjustable spring 400, in conjunction with the longitudinal support 301, provides lateral support force to the hanger rod 200, giving the hanger rod 200 a certain degree of elasticity when it deflects laterally, thus buffering the vibration of the compressor and achieving the effect of vibration reduction for the compressor.

[0044] Optionally, a limiting rubber pad 303 is provided on the side of the longitudinal support 301 facing the hanger 200. In this way, the limiting rubber pad 303 limits the vibration amplitude of the compressor, preventing the compressor from colliding with the longitudinal support 301 when the vibration amplitude is too large, thus avoiding damage to the longitudinal support 301. It also prevents the hanger 200 from excessively compressing the adjustable spring 400, thus preventing damage to the adjustable spring 400, thereby improving the overall stability of the vibration isolation device.

[0045] Optionally, the upper side of the boom 200 is connected to the support leg 300 via a hemispherical connector 304. This connection of the boom 200 with the hemispherical connector 304 improves the stability of the connection between the boom 200 and the support leg 300, thereby better securing the compressor.

[0046] Optionally, the hemispherical connector 304 is made of rubber. Rubber has a certain deformation capacity, and by using the rubber hemispherical connector 304 to connect the hanger 200 and the support leg 300, a flexible connection is formed between the hanger 200 and the support leg 300. This allows the hanger 200 to have a certain amount of swaying displacement, thereby damping the compressor when it vibrates, reducing compressor vibration and noise.

[0047] Optionally, the hemispherical connector 304 has a notch, and the hanger 200 has a spherical stop. The hanger 200 can pass through the notch and movably mount the spherical stop on the upper side of the hemispherical connector 304. This improves the ease of connection between the hemispherical connector 304 and the hanger 200, and facilitates the fixed connection of the compressor using a vibration isolation device.

[0048] Optionally, the motion acquisition module 500 includes a compressor frequency acquisition unit 501 for acquiring the vibration frequency of the compressor, and a controller assembly 600 for controlling the stiffness of the adjustable spring 400 according to the vibration frequency of the compressor. In this way, by acquiring the vibration frequency of the compressor and controlling the stiffness of the adjustable spring 400, the vibration frequency of the boom 200 is changed, avoiding the risk of resonance between the boom 200 and the compressor, effectively reducing the vibration amplitude of the compressor and the boom 200, and thus ensuring the stability between the compressor and the boom 200.

[0049] Understandably, the compressor frequency acquisition unit 501 is connected to the compressor's electronic control main board to acquire the compressor's operating data, and the compressor's vibration frequency is determined as the compressor's vibration frequency. Obtaining the compressor's vibration frequency directly from the data makes it simpler and faster to determine the compressor's vibration frequency.

[0050] Understandably, the compressor frequency acquisition unit 501 is a vibration sensor. The vibration sensor is installed on the compressor and acquires the compressor's vibration frequency by directly detecting the compressor's vibration. In this way, the acquisition of the compressor's vibration frequency is more accurate and can more realistically reflect the compressor's vibration frequency.

[0051] Optionally, the motion acquisition module 500 also includes a displacement acquisition unit 502 for acquiring the vibration amplitude of the compressor, and the controller assembly 600 is further used to control the stiffness of the adjustable spring 400 based on the vibration amplitude of the compressor. In this way, by acquiring the displacement deviation of the compressor, the vibration amplitude of the compressor can be determined, improving the convenience of acquiring the compressor vibration amplitude. Understandably, the displacement acquisition unit 502 is a displacement sensor with mature technology at present, and its specific structure is common knowledge or conventional in the field, and will not be described in detail here.

[0052] Optionally, the adjustable spring 400 includes a spring body 401 and an adjustment mechanism 402. The adjustment mechanism 402 is disposed on both sides of the spring body 401 and is used to compress the spring body 401, thereby changing the stiffness of the spring body 401. In this way, the stiffness of the spring body 401 changes when it is compressed. By setting the spring body 401 and the adjustment mechanism 402, the stiffness of the spring body 401 can be adjusted by applying different compressive forces to the spring body 401 using the adjustment mechanism 402. This allows for convenient and stable changes in the overall stiffness of the adjustable spring 400, better meeting usage requirements.

[0053] Optionally, the adjustment mechanism 402 includes two electromagnet plates 403, which are respectively fixed at both ends of the spring body 401. By adjusting the magnetic force of the electromagnet plates 403, the attractive force between the two electromagnet plates 403 is changed, thereby adjusting the compression force on the spring body 401. In this way, by controlling the energized current, the magnetic force of the electromagnet plates 403 can be precisely changed, thereby more stably and accurately controlling the compression force on the spring body 401. This makes it easier to adjust the stiffness of the spring body 401. By precisely adjusting the stiffness of the spring body 401, the lateral support force of the adjustable spring 400 on the boom 200 can be better controlled, thereby better adjusting the vibration frequency of the boom 200 and avoiding resonance between the boom 200 and the compressor.

[0054] Optionally, the adjusting mechanism 402 further includes a fixing plate 404, which is fixedly connected to both ends of the spring body 401. An electromagnet plate 403 is disposed on the fixing plate 404, wherein the diameter of the electromagnet plate 403 is smaller than the diameter of the spring body 401, and partially extends into the spring body 401. By placing the electromagnet plate 403 inside the spring body 401, the spring body 401 can be prevented from affecting the mutual attraction between the two electromagnet plates 403. Furthermore, the mutual attraction between the electromagnet plates 403 brings the two fixing plates 404 closer together, thereby compressing the spring body 401 and increasing its stiffness. By changing the attraction between the electromagnet plates 403, the stiffness of the entire adjustable spring 400 can be adjusted efficiently and stably.

[0055] It is understandable that the adjustable spring 400 can also be a ready-made electromagnetic spring, the specific structure of which is well known to those skilled in the art and will not be described again.

[0056] Optionally, the vibration isolation device further includes a vibration detection module 700. The vibration detection module 700 is mounted on the boom 200 and is used to acquire the vibration frequency of the boom 200. The controller assembly 600 is also connected to the vibration detection module 700 and is used to jointly control the stiffness of the adjustable spring 400 based on the vibration frequency of the boom 200 and the compressor's motion data. In this way, by detecting the vibration frequency of the boom 200 through the vibration detection module 700, the difference between the vibration frequency of the boom 200 and the compressor's vibration frequency can be determined in real time. Based on this, the stiffness of the adjustable spring 400 can be controlled, allowing for more accurate control of the boom 200's vibration frequency to avoid the compressor's vibration frequency and better prevent resonance between the two.

[0057] Optionally, the vibration isolation device also includes a damping base 800. The damping base 800 is installed at the bottom of the compressor. In this way, by placing the damping base 800 at the bottom of the compressor, the compressor can be reinforced and protected, avoiding shaking caused by excessive vibration amplitude during compressor start-up, and improving the stability of the compressor.

[0058] Optionally, the damping base 800 includes: a fixed chassis 801, a compressor mounting plate 802, and a piston portion 803, with the fixed chassis 801 and the compressor mounting plate 802 connected via the piston portion 803. In this way, by connecting the fixed chassis 801 to the bottom of the casing and the compressor mounting plate 802 to the compressor, with the piston portion 803 providing a movable connection and buffer, the vibration of the compressor can be buffered, preventing excessive stress on the compressor from causing damage.

[0059] Optionally, the piston section 803 includes a rubber sleeve and a rubber piston, one of which is connected to the fixed chassis 801 and the other to the compressor fixed plate 802. The rubber piston is confined within the rubber sleeve and has friction between it and the rubber sleeve. In this way, the high friction between the rubber sleeve and the rubber piston is used to buffer the vibration of the compressor, providing better protection for the compressor and maintaining the stability of compressor operation.

[0060] Optionally, a rubber support seat is provided on the lower side of the connection between the bottom of the hanger 200 and the compressor. This provides support from below at the connection point between the hanger 200 and the compressor, further improving the stability of the compressor.

[0061] Combination Figure 8 As shown, this disclosure provides a control method for a vibration isolation device, including:

[0062] S01, determine the compressor's motion data;

[0063] S02 controls the stiffness of the adjustable spring based on the compressor's motion data.

[0064] The control method for vibration isolation devices provided in this disclosure acquires the motion data of the compressor and controls the stiffness of the adjustable spring accordingly. This changes the supporting force of the adjustable spring on the connected rod, altering its suppression effect on the rod's vibration. The vibration frequency of the rod is changed, creating a gap between it and the compressor's vibration frequency, reducing the risk of resonance between the two, preventing resonance between the overall vibration isolation device and the compressor, reducing radiated noise, and improving the user experience.

[0065] Combination Figure 9 As shown, optionally, in step S02, the stiffness of the adjustable spring is controlled based on the compressor's motion data, including:

[0066] S21, while determining the compressor's motion data, acquire the vibration frequency of the boom;

[0067] S22 controls the stiffness of the adjustable spring based on the difference between the compressor's motion data and the vibration frequency of the boom.

[0068] By detecting the vibration frequency of the boom, the difference between the boom's vibration frequency and the compressor's vibration frequency can be determined in real time. Based on this, the stiffness of the adjustable spring can be controlled more accurately to avoid the compressor's vibration frequency and better prevent resonance between the two.

[0069] Optionally, the compressor's motion data includes: the compressor's vibration frequency and / or the compressor's vibration amplitude. Thus, the adjustable spring can be adjusted and controlled based on both the compressor's vibration frequency and amplitude, thereby changing the spring's stiffness and controlling the lateral support force on the hanger. Controlling the adjustable spring based on the compressor's vibration frequency allows the hanger's vibration frequency to avoid resonating with the compressor. Controlling the adjustable spring based on the compressor's vibration amplitude, by changing the lateral support force on the hanger, can suppress the compressor's vibration amplitude, preventing excessive vibration and reducing vibration noise.

[0070] Understandably, controlling the stiffness of the adjustable spring based on the difference between the compressor's motion data and the suspension rod's vibration frequency means adjusting the spring's stiffness according to this difference. By controlling the spring's stiffness by comparing the compressor's and suspension rod's vibration frequencies, resonance between the two can be better avoided, preventing an increase in amplitude.

[0071] like Figure 10 As shown, optionally, controlling the stiffness of the adjustable spring based on the difference between the compressor's vibration frequency and the boom's vibration frequency includes:

[0072] S23, Calculate the difference between the vibration frequency of the compressor and the vibration frequency of the boom;

[0073] S24, if the difference between the vibration frequency of the compressor and the vibration frequency of the boom is greater than or equal to the first threshold, control the adjustable spring to maintain the current stiffness;

[0074] S25, if the difference between the vibration frequency of the compressor and the vibration frequency of the boom is less than the first threshold, control the adjustable spring to increase or decrease its stiffness.

[0075] Thus, resonance between the compressor and the suspension rod refers to the same vibration frequency between the two. Therefore, considering the detection error of the vibration sensor, when the difference between the two is greater than or equal to the first threshold, it indicates that there is a significant difference in the vibration frequency between the two, and resonance will not occur. At this time, maintaining the current stiffness of the adjustable spring can prevent resonance between the compressor and the vibration isolation device. When the difference between the two is less than the first preset value, it indicates that the vibration frequency between the two is relatively close, and the possibility of resonance between the compressor and the vibration isolation device is high. At this time, by increasing or decreasing the stiffness of the adjustable spring, the vibration frequency of the vibration isolation device can be changed, so that the vibration frequency between the two can be separated to a certain extent. This can effectively prevent resonance between the compressor and the vibration isolation device, avoid excessive vibration amplitude, effectively reduce noise, and improve the overall stability of the vibration isolation device.

[0076] Optionally, the value of the first threshold is determined based on the vibration frequency of the compressor. Since the compressor's vibration is the source of vibration, setting the first threshold based on the compressor's vibration frequency and controlling the vibration frequency of the boom accordingly can effectively prevent the boom's vibration frequency from approaching the compressor's vibration frequency, reducing the risk of resonance and improving the overall stability of the vibration isolation device.

[0077] Optionally, the first threshold is 1% to 3% of the compressor's vibration frequency. Preferably, the first threshold is 2% of the compressor's operating frequency. In this way, resonance is generally possible when the vibration frequencies of two objects are within 3% of each other. Therefore, by setting the first threshold within 1% to 3%, the stiffness of the adjustable spring is adjusted when the difference between the compressor's vibration frequency and the suspension rod's vibration frequency is less than 1% to 3% of the compressor's vibration frequency. This changes the suspension rod's vibration frequency, better preventing resonance between the compressor and the suspension rod, eliminating stress risks in the vibration isolation device, and improving the stability of the vibration isolation device.

[0078] For example, if the first threshold is 2% of the compressor's vibration frequency, and the compressor's vibration frequency is 50 Hz, then the value of the first threshold is 1 Hz.

[0079] like Figure 11As shown, optionally, in step S25, if the difference between the vibration frequency of the compressor and the vibration frequency of the boom is less than a first threshold, the stiffness of the adjustable spring is controlled to be increased or decreased, including:

[0080] S26, obtain the current stiffness of the adjustable spring;

[0081] S27, if the current stiffness of the adjustable spring is determined to be within the first preset range, control the increase of the stiffness of the adjustable spring.

[0082] S28, if the current stiffness of the adjustable spring is determined to be within the second preset range, control the reduction of the stiffness of the adjustable spring.

[0083] In this way, when it is necessary to adjust the stiffness of the adjustable spring, the current stiffness of the adjustable spring can be obtained. Based on the range of the current stiffness of the adjustable spring, the stiffness of the adjustable spring can be controlled to increase or decrease. Specifically, if the current stiffness of the adjustable spring is high, the stiffness of the adjustable spring is decreased, and if the current stiffness of the adjustable spring is low, the stiffness of the adjustable spring is increased. This allows for reasonable adjustment of the stiffness of the adjustable spring within its adjustable range, thereby changing the vibration frequency of the boom, preventing resonance between the boom and the compressor, and preventing damage to the adjustable spring or adjustment failure caused by exceeding its adjustable range when adjusting the stiffness.

[0084] Optionally, an adjustable range for the stiffness of the adjustable spring is determined. A first preset range is the first half of the adjustable spring's stiffness range, and a second preset range is the second half. The range of the first preset range is larger than that of the second preset range. Since the first preset range is the first half of the adjustable spring's stiffness range, if the current stiffness is within the first preset range, it indicates that the adjustable spring has room for stiffness increase. Therefore, the stiffness of the adjustable spring can be increased. Conversely, if it is within the second preset range, the stiffness of the adjustable spring can be decreased. The fact that the first preset range is larger than the second preset range increases the probability of increasing the stiffness of the adjustable spring during the adjustment phase. Prioritizing the increase of the adjustable spring's stiffness can improve the lateral support force on the boom and better suppress the boom's vibration amplitude.

[0085] Optionally, the adjustable stiffness range of the adjustable spring is determined, with the first preset range being the first four-fifths of the adjustable stiffness range of the adjustable spring, and the second preset range being the last one-fifth of the adjustable stiffness range of the adjustable spring. Thus, by determining the adjustable range of the spring's stiffness, the adjustment strategy for the spring can be controlled. When the current stiffness of the adjustable spring is within the first four-fifths of its adjustable range, it indicates that the spring's stiffness still has room for adjustment. Therefore, prioritizing the increase of the spring's stiffness can change the vibration frequency of the boom, creating a gap between it and the compressor's vibration frequency to avoid resonance. Increasing the spring's stiffness also further enhances the lateral support force on the boom, reducing its vibration amplitude and improving vibration damping and noise reduction. When the current stiffness of the adjustable spring is within the last one-fifth of its adjustable range, it indicates that the spring's stiffness is about to reach its upper limit. Continuing to increase it at this point could damage the spring, or it might not meet the adjustment requirements even after reaching the upper limit. Therefore, prioritizing the decrease of the spring's stiffness allows for a wider adjustable range, better ensuring a gap between the vibration frequency of the vibration isolation device and the compressor's vibration frequency, thus avoiding resonance.

[0086] Optionally, after controlling the stiffness of the adjustable spring based on the difference between the vibration frequency of the compressor and the vibration frequency of the boom, the method further includes:

[0087] Obtain the vibration amplitude of the compressor;

[0088] The stiffness of the adjustable spring is further adjusted based on the vibration amplitude of the compressor.

[0089] Optionally, the stiffness of the adjustable spring can be further adjusted according to the vibration amplitude of the compressor, including:

[0090] If the vibration frequency of the boom is greater than that of the compressor, and the vibration amplitude of the compressor is greater than the set amplitude, the stiffness of the adjustable spring is further increased.

[0091] Understandably, the stiffness of an adjustable spring can be represented by the current flowing through the electromagnet plates. The current determines the magnitude of the attractive force between the electromagnet plates, and the magnitude of the attractive force directly affects the pressure exerted on the spring seat, thus affecting the stiffness of the adjustable spring.

[0092] Understandably, there is a clear one-to-one correspondence between the current flowing through the electromagnet and the stiffness of the adjustable spring. This correspondence can be obtained through adjustment experiments and pre-stored in the controller assembly for use when determining the current stiffness of the adjustable spring. Thus, determining the stiffness of the adjustable spring through a pre-set correspondence improves the convenience of stiffness determination.

[0093] Combination Figure 12As shown, this disclosure provides another control method for vibration isolation devices, including:

[0094] S03, adjust the stiffness of the adjustable spring to the maximum value of its adjustable stiffness range;

[0095] S04, if the difference between the vibration frequency of the compressor and the vibration frequency of the boom is less than the first threshold, control the adjustable spring to reduce the stiffness of the adjustable spring.

[0096] By setting the initial stiffness of the adjustable spring to its maximum value, a high lateral support force can be provided to the suspension rod during the compressor's start-up phase, effectively suppressing the vibration of the suspension rod and the compressor. When there is no risk of resonance between the suspension rod and the compressor, the suspension rod exerts optimal fixing force, improving the overall stability of the vibration isolation device. When the difference between the compressor's vibration frequency and the vibration isolation device's vibration frequency is less than the first threshold, indicating a risk of resonance between the compressor and the vibration isolation device, the stiffness of the adjustable spring is reduced to change the vibration frequency of the suspension rod, thereby widening the gap between it and the compressor's vibration frequency and preventing resonance between the two.
