[0002] As a high-speed rail transportation tool, the vibration suppression technology of maglev trains is crucial to ensure passenger comfort and train operation stability. In the prior art, the vibration suppression system of maglev trains usually uses traditional vibration-damping elements such as air springs or rubber materials to absorb and isolate vibrations from the track. These elements are arranged at key positions between the train and the track to achieve lateral and vertical buffering effects. However, the performance of these traditional vibration suppression elements is greatly affected by temperature, and their performance may degrade in low temperature environments, affecting the vibration suppression effect of the train. The vibration suppression system of the prior art also has insufficient monitoring and self-regulation capabilities. The aging and performance degradation of vibration suppression elements are difficult to monitor in real time, resulting in a lack of predictability in maintenance and replacement, which may affect the safety of train operation at critical moments.

[0019] See also Figures 1 to 7 As shown, an embodiment of the present application provides an intelligent vibration suppression device for a maglev train, comprising a magnet frame 1 and a plurality of beams 2 arranged at intervals on the magnet frame 1, and further comprising: a plurality of additional outer frames 3, two guide seats 4, a transverse slide 5, a transverse buffer table 6, a temperature regulating mechanism 7, a vertical buffer table 8 and a top connecting seat 9; A plurality of additional outer frames 3, each two in a group, are fixed on the parallel walls on the inner and outer sides of the magnet frame 1; two guide seats 4 are fixedly arranged at the top of each group of additional outer frames 3; a transverse slide 5 is movably clamped on the inner sides of the two guide seats 4, and one end of the transverse slide 5 facing the crossbeam 2 extends to the outer side of the additional outer frame 3; a transverse buffer table 6 is arranged on the outer wall of the additional outer frame 3 located on the inner side; a vertical buffer table 8 is arranged on the top of the transverse slide 5; a top connecting seat 9 is connected to the top of the vertical buffer table 8, and the top connecting seat 9 is used to connect the magnetic levitation car; a temperature regulating mechanism 7 is installed on the transverse slide 5, and the temperature regulating mechanism 7 includes at least one output end, and the output end of the temperature regulating mechanism 7 is connected to the transverse buffer table 6 and the vertical buffer table 8.

[0020] The design of the intelligent vibration suppression device for maglev trains aims at the problems existing in the existing vibration suppression technology of maglev trains, and realizes efficient and reliable vibration suppression effect through modular structure and intelligent control; in this application, the magnet frame 1 is used as the basis to provide a stable support structure, which acts on the maglev track; multiple beams 2 are arranged on the frame at intervals to enhance the overall rigidity; the additional outer frame 3 is fixed on the inner and outer wall surfaces of the frame, which increases the stability of the structure and the convenience of maintenance, and improves and strengthens the existing structure; the guide seat 4 is fixed on the top of the additional outer frame 3 to provide guidance for the transverse slide 5 to ensure its accuracy and stability during lateral movement; the transverse slide 5 is movably connected to the inner side of the guide seat 4, allowing it to move between the transverse buffer table 6 and the vertical buffer table 8 to meet the vibration suppression requirements in multiple directions. The transverse buffer table 6 is installed on the outer wall of the inner additional outer frame 3, connected to the transverse slide 5, and provides the main infrastructure for vibration suppression. The vertical buffer table 8 is installed on the top of the transverse slide 5 and connected to the top connecting seat 9. The vertical buffer table 8 is used to connect the maglev car to achieve the vibration suppression effect in the direction perpendicular to the track. The temperature regulating mechanism 7 is installed on the transverse slide 5, and is connected to the transverse buffer table 6 and the vertical buffer table 8 through at least one output end. The hardness or stiffness of the vibration suppression component is automatically adjusted according to the change of the ambient temperature to adapt to the operation in the low temperature environment and extend the service life of the vibration suppression component.

[0021] When the maglev train encounters vibration during operation, the lateral slide 5 and the vertical buffer platform 8 absorb and isolate the vibration through their elastic elements, and the temperature adjustment mechanism 7 monitors and adjusts the performance of the vibration suppression components in real time to adapt to different temperature conditions; this intelligent adjustment not only improves the vibration suppression effect, but also enhances the durability of the vibration suppression components, thereby improving the stability and safety of the maglev train operation.

[0022] like Figures 1 to 5 As shown, in some examples, further, the transverse slide 5 includes: a transverse plate 51 and a boss 52, the transverse plate 51 is slidably clamped between the two guide seats 4 and is located above the magnet frame 1; the boss 52 is fixedly mounted on the transverse plate 51 in a vertical state and is located at the bottom end of the transverse plate 51 on the side of the beam 2, and the boss 52 is also connected to the transverse buffer platform 6 to achieve transverse buffering between the car and the track.

[0023] In this example, specifically, the setting of the transverse slide 5 is the key part for realizing transverse buffering in the intelligent vibration suppression device of the maglev train, and is composed of a transverse plate 51 and a convex seat 52; the transverse plate 51 is the main structure of the transverse slide 5, which can slide along between the two guide seats 4 and is located above the magnet frame 1; the transverse plate 51 can freely move between the transverse buffer platform 6 and the track to cope with lateral vibrations; the convex seat 52 is fixed at the bottom end of the transverse plate 51 in a vertical state, close to the side of the crossbeam 2, and its function is to connect the transverse plate 51 with the transverse buffer platform 6 to form a vibration suppression bridge between the car and the track; when the maglev train is running on the track, if it encounters lateral vibrations, the convex seat 52 will absorb these vibrations through the transverse buffer platform 6 to reduce the impact transmitted to the car; at the same time, the design of the convex seat 52 also ensures the stability and accuracy of the transverse slide 5 when moving laterally, ensuring the continuity and reliability of the vibration suppression effect.

[0024] The lateral slide 5 provided in this example can not only effectively isolate the lateral vibration between the track and the car, thereby improving the comfort of passengers, but also automatically adjust the vibration suppression performance through the temperature adjustment mechanism 7 when the temperature changes to adapt to different operating environments; in addition, the modular design is also convenient for maintenance and replacement, thereby improving the reliability of the entire vibration suppression device and the convenience of maintenance.

[0025] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some examples, further, the transverse buffer platform 6 includes; a fixed seat 61, at least two transverse monitoring components 62 and a transverse corrugated sleeve 63, the fixed seat 61 is fixedly arranged on the outer wall of the additional outer frame 3 located on the side of the beam 2, and a groove is arranged in the fixed seat 61; at least two transverse monitoring components 62 are fixedly arranged in the groove of the fixed seat 61 in a group of two, the two transverse monitoring components 62 are arranged at intervals, and the protrusion 52 is located in the interval between the two transverse monitoring components 62; the transverse corrugated sleeve 63 is fixedly sleeved between the protrusion 52 and the inner wall of the fixed seat 61, and is respectively located on the outer side of the outer walls of multiple transverse monitoring components 62.

[0026] In this example, the transverse buffer platform 6 is designed to achieve the vibration suppression effect of the maglev train in the transverse direction. The transverse buffer platform 6 specifically includes a fixed seat 61; the fixed seat 61 is installed on the outer wall of the additional outer frame 3, and a groove is provided inside the fixed seat 61, which is used to accommodate the transverse monitoring component 62; the transverse monitoring component 62 is installed in pairs in the groove of the fixed seat 61, and the protrusion 52 is located in the interval between the two opposite transverse monitoring components 62, and is connected to the transverse plate 51 to form a vibration suppression node between the car and the track; the function of the transverse monitoring component 62 is to absorb and isolate the transverse vibration when the train is running. At the same time, they also have a monitoring function and can provide real-time feedback on the working status of the vibration suppression component (the specific working process will become clear in the subsequent description of the embodiment); the transverse corrugated sleeve 63 is fixedly sleeved between the protrusion 52 and the inner wall of the fixed seat 61, located on the outside of the transverse monitoring component 62, and plays a role in protection, heat insulation and auxiliary vibration suppression. At the same time, the design of the corrugated structure allows a certain degree of deformation to adapt to different vibration frequencies and amplitudes.

[0027] When the maglev train runs on the track and encounters lateral vibration, the vibration is first absorbed by the lateral monitoring component 62; the lateral monitoring component 62 reduces the vibration transmitted to the car through its elastic deformation; the boss 52 serves as a connection point to transmit the movement of the lateral slide 5 to the lateral monitoring component 62, and the lateral corrugated sleeve 63 provides additional vibration suppression and buffering effects, thereby enhancing the overall vibration suppression effect, thereby ensuring the smooth operation of the train; by monitoring the working status of the vibration suppression component, real-time monitoring and maintenance of the vibration suppression performance can be achieved, thereby extending the service life of the vibration suppression component; the addition of the lateral corrugated sleeve 63 enhances the durability and reliability of the vibration suppression system, and maintains efficient vibration suppression performance even in harsh operating environments, thereby providing passengers with a more comfortable and safe riding experience.

[0028] like Figures 1 to 5 , Figure 7 As shown, in some examples, further, the vertical buffer platform 8 includes; an air spring 81, a vertical corrugated sleeve 82, a plurality of vertical monitoring components 83 and at least one vertical vibration suppressor 84, the air spring 81 is fixedly arranged at the middle position of the top end of the transverse slide 5, and the top tube of the air spring 81 is connected to the bottom end of the top connecting seat 9; the vertical corrugated sleeve 82 is sleeved on the outside of the air spring 81 and connected between the top connecting seat 9 and the transverse slide 5; a plurality of vertical monitoring components 83 are fixedly connected between the top connecting seat 9 and the transverse slide 5; at least one vertical vibration suppressor 84, one end of which is rotatably connected to the top end of the transverse slide 5, and the other end of the vertical vibration suppressor 84 is connected between the two connecting end plates 85 on the edge of the top connecting seat 9.

[0029] In this example, the vertical buffer platform 8 is a key component for achieving vertical vibration suppression. The vertical buffer platform 8 mainly includes an air spring 81 to achieve basic vertical vibration suppression effect and is responsible for handling low-frequency vibrations; specifically, the air spring 81 is fixed to the middle of the top end of the transverse slide 5, and its top tube is connected to the bottom end of the top connecting seat 9. When the magnetic levitation vehicle vibrates in the vertical direction, it plays a role in buffering and supporting the weight of the car body, while allowing the car body to float in the vertical direction to a certain extent to cope with operating scenarios that generate vibrations; the vertical corrugated sleeve 82 is sleeved on the outside of the air spring 81, forming an independent protection for the air spring 81 including a wrapping space, and also provides additional vibration suppression, heat insulation and buffering effects, protecting the air spring 81 from the influence of the external environment and ensuring the service life of the air spring 81. ; The vertical monitoring component 83 is fixedly connected between the top connecting seat 9 and the transverse slide 5. The first function of the vertical monitoring component 83 is to monitor and absorb vertical vibrations to ensure the stability of the car. On the other hand, the monitoring vibration suppression component has a certain guiding role, ensuring that the vertical buffer platform 8 will not produce horizontal relative movement between the top connecting plate and the transverse slide 5 during the vibration suppression movement, ensuring that the components inside the vertical buffer platform 8 only need to face vertical impacts during the force process; in addition, the vertical vibration suppressor 84 is connected between the transverse slide 5 and the top connecting seat 9, which can absorb and reduce vibrations during rotation, improve the vibration suppression efficiency, and be used synchronously with the air spring 81; to further enhance the vibration suppression effect of this device on the vertical direction of the car.

[0030] When the maglev train runs on the track, the air spring 81 first bears the weight of the car and absorbs the vertical vibration; the vertical corrugated sleeve 82 provides auxiliary vibration suppression while the air spring 81 is working, thereby increasing the vibration suppression effect of the system; the vertical monitoring component 83 monitors the vertical vibration in real time, and absorbs and isolates the vibration through its design, thereby reducing the vibration impact transmitted to the car; the vertical vibration suppressor 84 absorbs and reduces the vibration through its rotating connection end, especially when running at high speed or turning, it can effectively reduce the swaying and vibration of the car, and is mainly responsible for handling high-frequency vibrations; thereby ensuring the stability of the car under various operating conditions; especially under high-speed operation and complex track conditions, providing passengers with a smoother and more comfortable riding experience.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in some examples, further, the temperature regulating mechanism 7 includes; a central control component 71, a guide fan 72, a first conveying channel 73 and a second conveying channel 74, the central control component 71 is arranged on the transverse slide 5, and the central control component 71 includes a ventilation channel; the guide fan 72 is arranged on the central control component 71, the input end of the guide fan 72 is connected to the normal temperature inner room in the car, and the output end of the guide fan 72 is connected to the ventilation channel of the central control component 71; the first conveying channel 73 is also connected to the output end of the guide fan 72, and the other end is connected to the inner cavity of the vertical corrugated sleeve 82; the second conveying channel 74 is also connected to the output end of the guide fan 72, and the other end is connected to the inner cavity of the transverse corrugated sleeve 63.

[0032] In this example, the temperature regulating mechanism 7 is the key to ensuring the vibration suppression effect of the train under various movement temperatures in the intelligent vibration suppression device of the maglev train, and it can also extend the service life of the device. Specifically, the temperature regulating mechanism 7 works together through the central control component 71, the guide fan 72, the first conveying channel 73 and the second conveying channel 74, wherein the central control component 71 is arranged on the transverse slide 5, and the ventilation channel is built in, serving as the control center of the entire temperature regulating mechanism 7; the guide fan 72 is arranged on the central control component 71, and the guide fan 72 inhales air from the normal temperature inner room in the car, and conveys the air to the ventilation channel of the central control component 71, which plays a role in regulating the air. The first conveying channel 73 is connected to the output end of the guide fan 72 and the inner cavity of the vertical corrugated sleeve 82, while the second conveying channel 74 is connected to the output end of the guide fan 72 and the inner cavity of the transverse corrugated sleeve 63; the function of these two conveying channels is to convey the air output from the guide fan 72 to the inner cavity of the vertical and transverse corrugated sleeves 63 respectively, and adjust the temperature in the sleeves by air flow, thereby ensuring that the physical properties of the vibration suppression components are always in an excellent state, while reducing the brittleness of rubber structural parts in low temperature environments and prolonging their service life.

[0033] When the maglev train runs in a low-temperature environment, the temperature regulating mechanism 7 delivers warm air to the inner cavity of the corrugated sleeve through the guide fan 72 to increase the temperature of the vibration suppression component to prevent the degradation of material properties due to low temperature; on the contrary, in a high-temperature environment, the operation of the guide fan 72 can be adjusted to deliver colder air into the sleeve to reduce the temperature of the vibration suppression component to prevent its performance from being affected by overheating; through this temperature regulation, it can be ensured that the vibration suppression component can maintain a good working condition under different temperature conditions; ensure the performance and durability of the vibration suppression component under extreme temperature conditions; realize real-time control of the temperature of the vibration suppression component, and enhance the adaptability of the vibration suppression system.

[0034] like Figure 6 As shown, in some examples, further, the boss 52 is also provided with: an inner channel 521, a plurality of air supply holes 522 and a first ceramic seat 523, the inner channel 521, the inner channel 521 is opened in the inner cavity of the boss 52, the inner channel 521 is connected to the output end of the second delivery channel 74; the plurality of air supply holes 522 are connected to the inner channel 521, the output end of the air supply hole 522 is located on the inner side of the transverse corrugated sleeve 63; the first ceramic seat 523 is fixedly arranged at both ends of the outer wall of the boss 52.

[0035] In this example, the inner channel 521 and the air supply hole 522 in the boss 52 are components used to further transmit airflow in the intelligent vibration suppression device of the maglev train; the inner channel 521 is a channel connected to the output end of the second delivery channel 74, providing a subsequent path for air flow; multiple air supply holes 522 are connected to the inner channel 521, and their function is to evenly distribute air to the inner side of the transverse corrugated sleeve 63, so as to achieve reliable control of the temperature of the vibration suppression component; in addition, the first ceramic seat 523 is fixed at both ends of the outer wall of the boss 52. Ceramic materials are generally used to withstand high loads and maintain structural stability due to their good thermal stability and wear resistance.

[0036] When the temperature regulating mechanism 7 is started, the guide fan 72 conveys air to the second conveying channel 74, and the air then flows into the inner channel 521 in the boss 52; the inner channel 521 guides the air to the air supply hole 522, and the air supply hole 522 evenly distributes the air to the inner side of the transverse corrugated sleeve 63, which can not only adjust the temperature in the corrugated sleeve, but also assist in vibration suppression through air flow; the first ceramic seat 523 serves as the fixed end of the boss 52, providing structural stability, ensuring that the boss 52 has sufficient strength when subjected to vibration force, and avoiding affecting nearby materials.

[0037] like Figure 6 As shown, in some examples, further, the lateral monitoring component 62 includes: at least two lateral rubber blocks 621, a protective sheet 622 and a first piezoelectric material layer 623, at least two lateral rubber blocks 621, one end of which is respectively fixed on the two lateral inner walls of the fixed seat 61; the protective sheet 622 is fixed at the other end of the lateral rubber block 621; the first piezoelectric material layer 623 is fixed on the outer side of the protective sheet 622 and corresponds to the position of the first ceramic seat 523.

[0038] In this example, the lateral monitoring component 62 is provided to achieve a vibration suppression effect in the lateral buffer platform 6 while providing energy recovery and aging monitoring functions; at least two lateral rubber blocks 621 are the main structure of the vibration suppression component, which play a role in absorbing and isolating the lateral vibration of the train; a protective sheet 622 is fixed to the other end of the lateral rubber block 621 to provide additional protection, especially for the first piezoelectric material layer 623, to prevent the first piezoelectric material layer 623 from frequently contacting with the rubber outer wall and circulating, and also to prevent the rubber block from being damaged; the first piezoelectric material layer 623 is fixed on the outside of the protective sheet 622, corresponding to the position of the first ceramic seat 523, by driving the first ceramic seat 523 when the train generates lateral vibration. The seat 523 impacts and moves between the two first piezoelectric materials, and the first piezoelectric material is deformed. The deformed first piezoelectric material can convert mechanical energy into electrical energy due to its own characteristics. When converted into electrical energy, the electrical energy can be stored and then meet the power supply of the guide fan 72 in the device. In addition, the amount of electricity output by the two first piezoelectric material layers 623 can be read. For example, in a specific mileage range, the power generation of the vehicle in the area in the past is A, but the power generation after running in this range is obviously greater than A. Therefore, the overall vibration amount generated by the train during operation changes, so that the vibration condition of the train can be known, and the aging or other damage of the transverse rubber block 621 can be known accordingly.

[0039] Working principle: When the maglev train encounters lateral vibrations during operation, the lateral rubber block 621 first absorbs these vibrations and reduces vibration transmission through its elastic deformation; the protective sheet 622 protects the lateral rubber block 621 and the first piezoelectric material layer 623 from damage, while ensuring that their vibration suppression performance is not affected; the first piezoelectric material layer 623 fits the stressed lateral rubber block 621 and follows the deformation, converting the mechanical energy of the deformation into electrical energy. By reading the generation of electrical energy, the working status of the vibration suppression component can be monitored, and its performance can be evaluated to see whether it is normal and whether it needs maintenance or replacement; thereby facilitating the maintenance and management of the vibration suppression system.

[0040] like Figure 7As shown, in some examples, further, the vertical monitoring component 83 includes: at least one fixed column 831, at least one sleeve 832, a connecting column 833, a second ceramic seat 834 and two second piezoelectric material layers 835, at least one fixed column 831 is fixedly arranged at the top of the transverse slide 5 in a vertical state; at least one sleeve 832 is fixedly arranged at the bottom end of the top connecting seat 9 in a vertical state, and can be movably sleeved on the top of the fixed column 831; the connecting column 833 is fixed at the middle position of the top of the fixed column 831 and is located in the inner cavity of the sleeve 832; the second ceramic seat 834 is fixedly arranged on the connecting column 833 and is located in the middle of the inner cavity of the sleeve 832; the two second piezoelectric material layers 835 are respectively fixedly arranged in the inner cavity of the sleeve 832 at the upper and lower ends of the second ceramic seat 834.

[0041] In this example, the vertical monitoring component 83 is provided to achieve a vibration suppression effect in the vertical buffer platform 8 while providing corresponding position monitoring and energy recovery functions; specifically, at least one fixed column 831 is vertically fixed to the top of the transverse slide 5, serving as the base of the entire vertical monitoring component 83, and the sleeve 832 can be movably mounted on the top of the fixed column 831, allowing vertical movement within a certain range when vertical vibration occurs, thereby generating relative movement between the fixed column 831 and the sleeve 832; the connecting column 833 serves as a structural member connecting the fixed column 831 and the second ceramic seat 834; when the train vibrates in the vertical direction, since the second ceramic seat 834 is fixed on the connecting column 833, it vibrates back and forth up and down in the middle of the inner cavity of the sleeve 832; and it contacts the two second piezoelectric material layers 835, and the mechanical energy generated by the vibration is converted into electrical energy.

[0042] Therefore, in this example, the connecting column 833 acts as an intermediate transmission member to transmit the vibration to the second ceramic seat 834, thereby affecting the second piezoelectric material layer 835; when the second piezoelectric material layer 835 is squeezed or stretched, the mechanical energy is converted into electrical energy according to the piezoelectric effect; the dual functions of energy recovery and vibration suppression status monitoring are realized, and the self-sufficiency and intelligence level of the system are improved; by monitoring the generation of electrical energy, the wear and aging of the vibration suppression components can be understood in real time, which provides convenience for maintenance and management.

[0043] In some examples, further, the central control component 71 also includes a temperature sensor, an alarm and a controller, wherein the temperature sensor is arranged on the air spring 81 and the transverse rubber block 621, the temperature sensor is connected to the signal input end of the controller, and the signal output end of the controller is connected to the alarm and the guide fan 72.

[0044] In this example, the central control component 71 integrates a temperature sensor, an alarm and a controller to realize the temperature monitoring and automatic adjustment function of the elastic deformation components in the intelligent vibration suppression device of the maglev train; the temperature sensor is directly arranged on the air spring 81 and the transverse rubber block 621. As the main components that directly bear and absorb vibration in the vibration suppression system, the temperature monitoring of the air spring 81 and the transverse rubber block 621 is particularly important; relevant research shows that the temperature generated by the vibration of rubber materials in different life cycles is different. Therefore, the temperature sensor used in this example can obtain the aging status of the air spring 81 and the transverse rubber block 621 by monitoring their operating temperature, and on the other hand, the temperature monitored by the temperature sensor can be the air spring 81 and the transverse rubber block 621. The ambient temperature of the area where the rubber block 621 is located, such as the external ambient temperature of the train, triggers the threshold in the controller when the temperature is low, and the controller further controls the guide fan 72 to start, so as to guide the room temperature air in the car to maintain the working temperature of the air spring 81 and the transverse rubber block 621; according to the specific temperature value difference (the temperature in the car and the outdoor temperature), the air flow is increased or decreased (achieved by adjusting to the speed of the guide classification) to provide cooling or heating for the air spring 81 and the transverse rubber block 621 to maintain them at the optimal working temperature; ensure that the vibration suppression components can maintain the best performance under various environmental conditions; therefore, the design of the central control component 71 provides an efficient and intelligent temperature monitoring and adjustment solution for the intelligent vibration suppression device of the maglev train.

[0045] In some examples, further, the central control component 71 is also provided with a power statistics module, an auxiliary power supply module and a battery, wherein the battery is respectively connected to the output ends of the first piezoelectric material layer 623 and the second piezoelectric material layer 835 through the power statistics module, and the battery is also connected to the auxiliary power supply module.

[0046] In this example, the central control component 71 further includes a power statistics module, an auxiliary power supply module and a battery for power management of the intelligent vibration suppression device of the maglev train; the power statistics module is responsible for monitoring and counting the electric energy generated by the first piezoelectric material layer 623 and the second piezoelectric material layer 835. The first piezoelectric material layer 623 and the second piezoelectric material layer 835 convert mechanical energy into electric energy and quantify it through the power statistics module, so that the power generation situation can be reflected in a direct digital form. Furthermore, the vibration situation generated by the current vehicle in the specified operating range can also be known through the power generation situation. Therefore, the data can be used as a basis for judging the vibration fault of the maglev train, such as whether there is aging of the air spring 81 and the transverse rubber block 621, or abnormal conditions in other components, so as to arrange staff to carry out maintenance; the battery is connected to the power statistics module, and the battery stores the electric energy generated by the piezoelectric material layer for use when needed.

[0047] The auxiliary power supply module is connected to the battery. The function of the auxiliary power supply module is to obtain electric energy from the battery when the guide fan 72 needs electricity, so as to provide power support for the guide fan 72 and other components. When the electric energy generated by the first piezoelectric material layer 623 and the second piezoelectric material layer 835 is insufficient to maintain the required operating speed of the guide fan 72 (the vehicle vibration is small), by connecting the battery to the auxiliary power supply module, the guide fan 72 in the vibration suppression device can also maintain normal operation.

[0048] In some examples, further, in order to further achieve the circulation effect of normal temperature air in the transverse corrugated sleeve 63 and the vertical corrugated sleeve 82, an exhaust hole (not shown in the figure) is optionally opened on the transverse corrugated sleeve 63 and the vertical corrugated sleeve 82. Therefore, when the guide fan 72 is started, the airflow enters the transverse corrugated sleeve 63 and the vertical corrugated sleeve 82 and can be discharged through the exhaust hole to ensure a continuous supply of normal temperature air.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
