Description

Technical Field

[0001] The present invention relates to the technical field of maglev trains, and particularly to an intelligent vibration suppression device for maglev trains. Background Art

[0002] As a high-speed rail transit tool, the vibration suppression technology of maglev trains is crucial for ensuring passenger comfort and train operation stability. In the prior art, the vibration suppression system of maglev trains usually uses traditional damping components such as air springs or rubber materials to absorb and isolate vibrations from the track. These components 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 components is greatly affected by temperature, and their performance may decline in low-temperature environments, affecting the vibration suppression effect of the train. The prior art vibration suppression system also lacks monitoring and self-adjusting capabilities. The aging and performance attenuation of vibration suppression components are difficult to monitor in real time, resulting in a lack of predictability in maintenance and replacement, which may affect the train operation safety at critical moments. Therefore, the prior art has obvious deficiencies in the persistence of vibration suppression effect and intelligent monitoring. Summary of the Invention

[0032] Please refer to Figures 1 to 7 As shown, the embodiments of the present application provide a maglev train intelligent vibration suppression device, which includes a magnet frame 1 and a plurality of cross beams 2 arranged at intervals on the magnet frame 1, and further includes: a plurality of additional outer frames 3, two guide seats 4, a transverse sliding table 5, a transverse buffer table 6, a temperature adjustment mechanism 7, a vertical buffer table 8 and a top connection seat 9;

[0033] Multiple additional outer frames 3, with every two of them fixed on the parallel wall surfaces on the inner and outer sides of the magnet frame 1 respectively as a group; two guiding seats 4, fixedly arranged at the top of each group of additional outer frames 3; a transverse sliding table 5, movably clamped inside the two guiding seats 4, and one end of the transverse sliding table 5 facing the cross beam 2 extends to the outside of the additional outer frame 3; a transverse buffer table 6, arranged on the outer wall of the inner additional outer frame 3; a vertical buffer table 8, arranged at the top of the transverse sliding table 5; a top connecting seat 9, connected to the top of the vertical buffer table 8, and the top connecting seat 9 is used to connect the maglev carriage; a temperature regulating mechanism 7, installed on the transverse sliding table 5, 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.

[0034] 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. Through modular structure and intelligent control, it realizes efficient and reliable vibration suppression effect; in this application, the magnet frame 1 serves as the basis, providing a stable support structure and acting on the maglev track; multiple cross beams 2 are arranged at intervals on the frame, enhancing the overall rigidity; the additional outer frames 3 are fixed on the inner and outer side walls of the frame, increasing the structural stability and the convenience of maintenance, and it is improved and strengthened on the existing structure; the guiding seats 4 are fixed at the top of the additional outer frames 3, providing guidance for the transverse sliding table 5 to ensure its accurate and stable movement in the transverse direction; the transverse sliding table 5 is movably clamped inside the guiding seats 4, allowing it to move between the transverse buffer table 6 and the vertical buffer table 8 to adapt to 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 and is connected to the transverse sliding table 5, providing the main infrastructure for vibration suppression. The vertical buffer table 8 is installed at the top of the transverse sliding table 5 and is connected to the top connecting seat 9. The vertical buffer table 8 is used to connect the maglev carriage to achieve the vibration suppression effect perpendicular to the track direction. The temperature regulating mechanism 7 is installed on the transverse sliding table 5 and is connected to the transverse buffer table 6 and the vertical buffer table 8 through at least one output end, automatically adjusting the hardness or stiffness of the vibration suppression components according to the change of the ambient temperature to adapt to the operation in low temperature environment and extend the service life of the vibration suppression components.

[0035] When the maglev train encounters vibration during operation, the transverse sliding table 5 and the vertical buffer table 8 absorb and isolate the vibration through their elastic elements, and the temperature regulating 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.

[0036] As Figures 1 to 5As shown, in some examples, further, the lateral sliding table 5 includes: a cross plate 51 and a convex seat 52. The cross plate 51 is slidably clamped between two guide seats 4 and is located above the magnet frame 1. The convex seat 52 is fixedly arranged on the cross plate 51 in a vertical state and is located at the bottom end of the cross plate 51 on the side of the cross beam 2. The convex seat 52 is also connected to the lateral buffer table 6 to achieve lateral buffering between the carriage and the track.

[0037] In this example, specifically, the setting of the lateral sliding table 5 is a key part for realizing lateral buffering in the maglev train intelligent vibration suppression device, which is composed of a cross plate 51 and a convex seat 52. The cross plate 51 is the main structure of the lateral sliding table 5, which can slide along between two guide seats 4 and is located above the magnet frame 1. By freely moving the cross plate 51 between the lateral buffer table 6 and the track, it can cope with lateral vibrations. The convex seat 52 is fixedly arranged at the bottom end of the cross plate 51 in a vertical state, adjacent to the side of the cross beam 2. Its function is to connect the cross plate 51 with the lateral buffer table 6 to form a vibration suppression bridge between the carriage and the track. When the maglev train runs on the track, if it encounters lateral vibrations, the convex seat 52 will absorb these vibrations through the lateral buffer table 6 and reduce the impact transmitted to the carriage. At the same time, the design of the convex seat 52 also ensures the stability and accuracy of the lateral sliding table 5 during lateral movement, ensuring the continuity and reliability of the vibration suppression effect.

[0038] Through the lateral sliding table 5 provided in this example, it can not only effectively isolate the lateral vibrations between the track and the carriage, improve 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, improving the reliability of the entire vibration suppression device and the convenience of maintenance.

[0039] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, in some examples, further, the lateral buffer table 6 includes: a fixed seat 61, at least two lateral monitoring components 62 and a lateral corrugated sleeve 63. The fixed seat 61 is fixedly arranged on the outer wall of the additional outer frame 3 on the side of the cross beam 2. A groove is provided in the fixed seat 61. At least two lateral monitoring components 62 are fixedly arranged in the groove of the fixed seat 61 in groups of two. The two lateral monitoring components 62 are arranged at intervals, and the convex seat 52 is located within the interval between the two lateral monitoring components 62. The lateral corrugated sleeve 63 is fixedly sleeved between the convex seat 52 and the inner wall of the fixed seat 61 and is located outside the outer walls of multiple lateral monitoring components 62 respectively.

[0040] In this example, the design of the lateral buffer platform 6 is to achieve the vibration suppression effect of the maglev train in the lateral direction. The lateral 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 it for accommodating the lateral monitoring component 62; the lateral monitoring components 62 are installed in pairs in the groove of the fixed seat 61, and the convex seat 52 is located within the interval between two opposite lateral monitoring components 62 and is connected to the cross plate 51 to form a vibration suppression node between the carriage and the track; the function of the lateral monitoring components 62 is to absorb and isolate lateral vibrations during train operation. At the same time, they also have a monitoring function and can provide real-time feedback on the working state of the vibration suppressor (the specific working process will become obvious in the subsequent embodiment description); the lateral corrugated sleeve 63 is fixedly sleeved between the convex seat 52 and the inner wall of the fixed seat 61, outside the lateral monitoring components 62, which 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.

[0041] When the maglev train runs on the track and encounters lateral vibrations, the vibrations are first absorbed by the lateral monitoring components 62; the lateral monitoring components 62 reduce the vibration transmission to the carriage through their elastic deformation; the convex seat 52, as a connection point, transmits the movement of the lateral sliding platform 5 to the lateral monitoring components 62, while the lateral corrugated sleeve 63 provides additional vibration suppression and buffering effects, enhancing the overall vibration suppression effect; thus ensuring the smooth operation of the train; by monitoring the working state of the vibration suppressor, real-time monitoring and maintenance of the vibration suppression performance can be achieved, extending the service life of the vibration suppression components; the addition of the lateral corrugated sleeve 63 enhances the durability and reliability of the vibration suppression system, and it can maintain high-efficiency vibration suppression performance even in harsh operating environments; providing a more comfortable and safe riding experience for passengers.

[0042] As Figures 1 to 5 、 Figure 7 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 lateral sliding platform 5, and the top pipe of the air spring 81 is connected to the bottom end of the top connection seat 9; the vertical corrugated sleeve 82 is sleeved outside the air spring 81 and is connected between the top connection seat 9 and the lateral sliding platform 5; a plurality of vertical monitoring components 83 are fixedly connected between the top connection seat 9 and the lateral sliding platform 5; at least one vertical vibration suppressor 84, one end of which is rotatably connected to the top end of the lateral sliding platform 5, and the other end of the vertical vibration suppressor 84 is connected between two connection end plates 85 at the edge of the top connection seat 9.

[0043] 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 the basic vertical vibration suppression effect and is responsible for handling low-frequency vibrations. Specifically, the air spring 81 is fixed at the middle of the top of the lateral sliding platform 5, and its top pipe is connected to the bottom end of the top connecting seat 9. When the maglev vehicle vibrates in the vertical direction, it plays a role in buffering and supporting the weight of the car body, and at the same time allows the car body to have a certain degree of floating in the vertical direction to cope with the operating scenarios that generate vibrations. The vertical corrugated sleeve 82 is sleeved outside the air spring 81, forming an independent protective including wrapping space for the air spring 81, and at the same time providing 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 lateral sliding platform 5. The role of the vertical monitoring component 83 in the first aspect is to monitor and absorb vertical vibrations to ensure the smoothness of the car body. On the other hand, the vibration suppression component has a certain guiding effect to ensure that there is no relative horizontal movement between the top connecting plate and the lateral sliding platform 5 during the vibration suppression movement of the vertical buffer platform 8, ensuring that the components inside the vertical buffer platform 8 only need to face the impact in the vertical direction during the force application process. In addition, the vertical vibration suppressor 84 is connected between the lateral sliding platform 5 and the top connecting seat 9, and 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 the device on the vertical direction of the car body.

[0044] When the maglev train runs on the track, the air spring 81 first bears the weight of the car body and absorbs the vertical vibrations; the vertical corrugated sleeve 82 provides an auxiliary vibration suppression effect while the air spring 81 is working, increasing the vibration suppression effect of the system; the vertical monitoring component 83 monitors the vertical vibration situation in real time and absorbs and isolates the vibrations through its design, reducing the vibration impact transmitted to the car body; the vertical vibration suppressor 84 absorbs and reduces vibrations through its rotating connection end, especially during high-speed operation or turning, and can effectively reduce the swaying and vibration of the car body, mainly responsible for handling high-frequency vibrations, thereby ensuring the stability of the car body under various operating conditions; especially under high-speed operation and complex track conditions, it provides a smoother and more comfortable riding experience for passengers.

[0045] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, in some examples, further, the temperature adjustment mechanism 7 includes a central control component 71, a diversion fan 72, a first conveying channel 73, and a second conveying channel 74. The central control component 71 is arranged on the lateral sliding table 5 and includes a ventilation channel. The diversion fan 72 is arranged on the central control component 71. The input end of the diversion fan 72 is connected to the normal-temperature inner chamber in the carriage, and the output end of the diversion 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 diversion 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 diversion fan 72, and the other end is connected to the inner cavity of the lateral corrugated sleeve 63.

[0046] In this example, the temperature adjustment mechanism 7 is the key to ensuring the vibration suppression effect of the maglev train intelligent vibration suppression device at various operating temperatures, and it can also extend the service life of this device. Specifically, the temperature adjustment mechanism 7 works together through the central control component 71, the diversion fan 72, the first conveying channel 73, and the second conveying channel 74. The central control component 71 is arranged on the lateral sliding table 5 and has a built-in ventilation channel, serving as the control center of the entire temperature adjustment mechanism 7. The diversion fan 72 is arranged on the central control component 71. The diversion fan 72 sucks air from the normal-temperature inner chamber in the carriage and transports the air to the ventilation channel of the central control component 71, playing a role in regulating air flow and also ensuring the operating temperature of the central control component 71 to avoid malfunction problems caused by inappropriate temperature. The first conveying channel 73 is connected to the output end of the diversion 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 diversion fan 72 and the inner cavity of the lateral corrugated sleeve 63. The function of these two conveying channels is to transport the air output from the diversion fan 72 to the inner cavities of the vertical and lateral corrugated sleeves 63 respectively, and regulate the temperature inside the sleeves through air flow, thereby ensuring that the physical properties of the vibration suppression components are always in an excellent state, reducing the brittleness of rubber structure parts in a low-temperature environment, and enhancing their service life.

[0047] When the maglev train operates in a low-temperature environment, the temperature adjustment mechanism 7 transports warm air to the inner cavity of the corrugated sleeve through the diversion fan 72 to increase the temperature of the vibration suppression components and prevent the decline of material properties caused by low temperature. On the contrary, in a high-temperature environment, the operation of the diversion fan 72 can be adjusted to transport relatively cold air into the sleeve to reduce the temperature of the vibration suppression components and prevent their performance from being affected by overheating. Through this temperature adjustment, it can be ensured that the vibration suppression components can maintain a good working state under different temperature conditions, ensure the performance and durability of the vibration suppression components under extreme temperature conditions, realize real-time control of the temperature of the vibration suppression components, and enhance the adaptability of the vibration suppression system.

[0048] As Figure 6 shown, in some examples, further, an inner channel 521, a plurality of air supply holes 522, and a first ceramic seat 523 are further provided in the convex seat 52. The inner channel 521 is opened in the inner cavity of the convex seat 52 and 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, and the output ends of the air supply holes 522 are located inside the transverse corrugated sleeve 63; the first ceramic seat 523 is fixedly arranged at both ends of the outer wall of the convex seat 52.

[0049] In this example, the inner channel 521 and the air supply holes 522 in the convex seat 52 are components for further transporting air flow in the intelligent vibration suppression device of the maglev train; the inner channel 521 is a channel connecting the output end of the second delivery channel 74, providing a subsequent path for air flow; the plurality of air supply holes 522 are connected to the inner channel 521, and their function is to evenly distribute air to the inside of the transverse corrugated sleeve 63 to achieve reliable control of the temperature of the vibration suppression components; in addition, the first ceramic seat 523 is fixed at both ends of the outer wall of the convex seat 52. Ceramic materials are usually used to bear high loads and maintain structural stability due to their good thermal stability and wear resistance.

[0050] When the temperature adjustment mechanism 7 is activated, the diversion fan 72 transports air to the second delivery channel 74, and the air then flows into the inner channel 521 in the convex seat 52; the inner channel 521 guides the air to the air supply holes 522, and the air supply holes 522 evenly distribute the air to the inside of the transverse corrugated sleeve 63. This can not only adjust the temperature inside the corrugated sleeve but also assist in vibration suppression through air flow; the first ceramic seat 523, as the fixed end of the convex seat 52, provides structural stability, ensuring that the convex seat 52 has sufficient strength when bearing vibration forces and avoiding affecting nearby materials.

[0051] As Figure 6 shown, in some examples, further, the transverse monitoring component 62 includes: at least two transverse rubber blocks 621, a protective sheet 622, and a first piezoelectric material layer 623. At least two transverse rubber blocks 621, one end of which is respectively fixedly arranged on the inner walls of the two sides in the transverse direction inside the fixed seat 61; the protective sheet 622 is fixedly arranged at the other end of the transverse rubber blocks 621; the first piezoelectric material layer 623 is fixedly arranged on the outer side of the protective sheet 622 and corresponds to the position of the first ceramic seat 523.

[0052] In this example, the lateral monitoring component 62 is provided to achieve vibration suppression effect in the lateral buffer table 6 while providing energy recovery and aging monitoring functions; at least two lateral rubber blocks 621 are the main structures of the vibration suppression components, which play the role of absorbing and isolating the lateral vibration of the train; the protective sheet 622 is fixed at 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 coming into frequent contact with the outer wall of the rubber and causing cycling, and also to prevent damage to the rubber block; the first piezoelectric material layer 623 is fixed outside the protective sheet 622 and corresponds to the position of the first ceramic seat 523. When the train generates lateral vibration, the first ceramic seat 523 is driven to impact and move between the two first piezoelectric materials, and the first piezoelectric material deforms. Under its own characteristics, the deformed first piezoelectric material can convert mechanical energy into electrical energy. When the electrical energy is converted, the electrical energy can be stored and then used to supply power to the diversion fan 72 in this device; in addition, the amount of electricity output by the two first piezoelectric material layers 623 can be read. For example, in a specific running kilometer interval, the power generation of the vehicle running in this area in the past was A, but the power generation after running in this interval this time is significantly greater than A. Therefore, the overall vibration amount generated during the running of this train has changed, so as to know the vibration situation of the train and correspondingly know the aging or other damage conditions of the lateral rubber block 621.

[0053] Working principle: When the maglev train encounters lateral vibration 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, and at the same time ensures that its vibration suppression performance is not affected; the first piezoelectric material layer 623 adheres to the stressed lateral rubber block 621 and follows the deformation, converting the mechanical energy of the deformation action into electrical energy. By reading the generation situation of the electrical energy, the working state of the vibration suppression component can be monitored, and its performance can be evaluated whether it is normal and whether maintenance or replacement is required; thus, it provides convenience for the maintenance and management of the vibration suppression system.

[0054] Such as Figure 7As shown, in some examples, further, the vertical monitoring component 83 includes: at least one fixing post 831, at least one sleeve 832, a connecting post 833, a second ceramic seat 834, and two second piezoelectric material layers 835. At least one fixing post 831 is fixedly arranged vertically at the top end of the transverse slide 5; at least one sleeve 832 is fixedly arranged vertically at the bottom end of the top connecting seat 9 and can movably sleeve on the top of the fixing post 831; the connecting post 833 is fixed at the middle position of the top end of the fixing post 831 and is located in the inner cavity of the sleeve 832; the second ceramic seat 834 is fixedly arranged on the connecting post 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.

[0055] In this example, the vertical monitoring component 83 is provided to achieve the vibration suppression effect in the vertical buffer table 8 while providing the functions of monitoring and energy recovery at the corresponding positions; specifically, at least one fixing post 831 is vertically fixed at the top end of the transverse slide 5 as the base of the entire vertical monitoring component 83. The sleeve 832 can movably sleeve on the top of the fixing post 831 and allows a certain range of vertical movement when generating vertical vibration, thus generating relative movement between the fixing post 831 and the sleeve 832; the connecting post 833 is a structural member connecting the fixing post 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 post 833 and reciprocates up and down in the middle of the inner cavity of the sleeve 832; and contacts the two second piezoelectric material layers 835, the mechanical energy generated by the vibration is converted into electrical energy.

[0056] Therefore, in this example, the connecting post 833 serves 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, it converts mechanical energy into electrical energy according to the piezoelectric effect; realizing the dual functions of energy recovery and vibration suppression state monitoring, improving the self-sufficiency ability and intelligent level of the system; by monitoring the generation of electrical energy, the wear and aging conditions of the vibration suppression components can be understood in real time, providing convenience for maintenance and management.

[0057] In some examples, further, the central control component 71 further includes a temperature sensor, an alarm, and a controller. 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 diversion fan 72.

[0058] In this example, the central control component 71 integrates a temperature sensor, an alarm, and a controller to achieve temperature monitoring and automatic adjustment functions for the elastic deformation components in the maglev train intelligent vibration suppression device; the temperature sensor is directly set on the air spring 81 and the lateral rubber block 621. As the main components directly bearing and absorbing vibrations in the vibration suppression system, it is particularly important to monitor the temperatures of the air spring 81 and the lateral rubber block 621; relevant research shows that the temperatures generated by rubber materials during vibration are different at different life cycle stages. Therefore, on the one hand, the temperature sensor adopted in this example can obtain their aging conditions by monitoring the operating temperatures of the air spring 81 and the lateral rubber block 621. On the other hand, the temperature monitored by the temperature sensor can be the ambient temperature in the areas where the air spring 81 and the lateral rubber block 621 are located, such as the external ambient temperature during train operation. When the temperature is low, it triggers the threshold in the controller, and the controller further controls the start of the diversion fan 72 to guide the normal-temperature air in the carriage to maintain the operating temperatures of the air spring 81 and the lateral rubber block 621; according to the specific temperature value differences (the temperature inside the carriage and the outdoor temperature), by increasing or decreasing the air flow rate (achieved by adjusting the rotation speed of the diversion grading), cooling or heating is provided for the air spring 81 and the lateral rubber block 621 to maintain their optimal operating temperatures; ensuring 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 maglev train intelligent vibration suppression device.

[0059] In some examples, furthermore, a power consumption statistics module, an auxiliary power supply module, and a storage battery are also provided on the central control component 71. The storage 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 consumption statistics module, and the storage battery is also connected to the auxiliary power supply module.

[0060] In this example, the central control component 71 further includes a power statistics module, an auxiliary power supply module, and a storage battery for power management of the maglev train intelligent vibration suppression device. The power statistics module is responsible for monitoring and counting the electrical 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 electrical energy, which is quantified by the power statistics module. Thus, the power generation situation can be reflected by straightforward numbers. Further, the vibration situation generated by the current vehicle within the specified operating range can be known through the power generation situation. Therefore, this data can be used as a basis for judging faults in the vibration of this maglev train, such as whether there is aging of the air spring 81 and the lateral rubber block 621, or whether there are abnormalities in other components, so as to arrange for staff to carry out maintenance. The storage battery is connected to the power statistics module and stores the electrical energy generated by the piezoelectric material layer for use when needed.

[0061] The auxiliary power supply module is connected to the storage battery. The function of the auxiliary power supply module is to obtain electrical energy from the storage battery to provide power support for components such as the diversion fan 72 when the diversion fan 72 needs power. When the electrical 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 diversion fan 72 (when the vehicle vibration is small), by connecting the storage battery to the auxiliary power supply module, the diversion fan 72 in the vibration suppression device can also operate normally.

[0062] In some examples, further, to further achieve the air circulation effect of the normal-temperature air inside the lateral corrugated sleeve 63 and the vertical corrugated sleeve 82, exhaust holes (not shown in the figure) are optionally provided on the lateral corrugated sleeve 63 and the vertical corrugated sleeve 82. Therefore, when the diversion fan 72 is started, after the air flow enters the lateral corrugated sleeve 63 and the vertical corrugated sleeve 82, it can be discharged through the exhaust holes to ensure continuous supply of normal-temperature air.

[0063] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
