Description

Technical Field

[0001] The invention relates to a frequency conversion cabinet with a multi-layer supporting mechanism. Background Art

[0002] The frequency converter cabinet is a control cabinet for the power device driven by the frequency converter. It has become the most popular power traction method due to its good starting performance, speed regulation performance and energy-saving effect. In actual applications, the frequency converter cabinet can be used in many application environments, such as indoors, outdoors, and in mines. Among them, when the frequency converter cabinet is used in a mine, since the structure of the mine itself is not very stable, there may be the possibility of falling rocks, or, since there is less space for activities inside the mine itself, some active equipment (excavators, etc.) will cause the mine to be unstable while mining, and the frequency converter cabinet will be affected by the falling rocks and hit the cabinet body, thereby causing damage to the frequency converter cabinet.

[0003] In order to prevent the frequency converter cabinet from being damaged, many earthquake-resistant, dust-proof and waterproof structures are currently provided. However, the earthquake-resistant structure itself is only to ensure that the frequency converter cabinet will not be affected by vibration. When the above situation occurs, the earthquake-resistant structure basically cannot ensure that the frequency converter cabinet is damaged.

[0004] Therefore, without destroying the earthquake resistance of the frequency converter cabinet, the research direction of the present invention is to design a support structure that can ensure that the top and sides of the frequency converter cabinet can be protected in harsh environments to avoid internal or external damage and can effectively resist impact. Summary of the invention

[0012] As a further improvement, a plurality of the rubber members are arranged obliquely in sequence between the first plate and the second plate.

[0013] As a further improvement, the support assembly includes a pivot seat, a connecting plate arranged between the pivot seats, an outward-expanding buffer rod rotatably arranged on the pivot seat, a reinforcing plate arranged on the upper and lower ends of the first side support plate and the second side support plate, a first spring arranged on the reinforcing plate, and a support member arranged at one end of the first spring.

[0014] As a further improvement, the sliding pressure relief component includes a pull rod, a claw hook arranged at one end of the pull rod, a second spring connected to the claw hook, an axle rod arranged on both sides of the top plate, a rotating shaft arranged at both ends of the axle rod, an inclined pressure plate arranged on the outer wall of the rotating shaft, and a pulley arranged at one end of the inclined pressure plate, and the pulley corresponds to a plurality of sliding grooves arranged on the inner cabinet body, and slides to the left and right sides to relieve pressure.

[0015] As a further improvement, the third support mechanism includes an impact column, a first connecting plate, a second force-bearing rod, a second connecting plate, a force column and a first force-bearing rod which are arranged in sequence below the impact column, the second force-bearing rod is located between the first connecting plate and the second connecting plate, the force column is located in the middle of the lower end of the second connecting plate, and the first force-bearing rod is located around the lower end of the second connecting plate.

[0016] As a further improvement, first damping particles are arranged between the first connecting plate and the second connecting plate.

[0017] As a further improvement, second damping particles are further arranged between the first connecting plate and the second connecting plate.

[0018] As a further improvement, the middle plate also includes a fourth support mechanism, which includes a first mounting plate and a second mounting plate, the first mounting plate is provided with an outer frame, a support portion is provided on the second mounting plate, a cavity filled with fourth damping particles is formed inside the support portion, a transverse support plate is provided in the cavity and placed above the fourth damping particles, a third spring is provided on the top of the transverse support plate, and the third spring is connected to the outer frame, the outer frame is covered at the top of the support portion, and a number of inflatable rubbers arranged at equal intervals are provided between the outer frame and the support portion; an installation cavity for filling third damping particles is also formed between the outer frame and the support portion, fixing plates are provided at both ends of the outer frame connected to the first mounting plate, an installation seam is formed between the first mounting plate and the support portion, and the installation seam is filled with foam gel for connecting the first mounting plate and the support portion.

[0019] The beneficial effects of the present invention are as follows: (1) When an external force acts on the upper support plate, the force is first transmitted to the connecting plates on both sides. Since one end of the connecting plate is provided with an inclined rod inclined toward the upper right, this inclined design helps to disperse the impact force and reduce the force directly acting on one point. The inclined rod is connected to the hollow groove on the inclined plate. This design can absorb and disperse the impact force through the deformation of the hollow groove when the inclined rod is subjected to force, thereby reducing the bending stress of the inclined rod. In the hidden groove formed on the outer wall of the inclined rod, a force-bearing frame and a buffer composed of a first plate, a second plate and a rubber member are provided. Due to its high elasticity and viscoelasticity, the rubber member can effectively absorb the impact force and reduce the damage to the structure. The first ring and the second ring provided at one end of the inclined rod, and the third spring connected to the outer frame, jointly limit the range of motion of the first ring and improve the connection stability between the inclined rod and the hollow groove. In summary, the structure realizes effective absorption and dispersion of the impact force through the combination of multiple shock-absorbing elements, thereby improving the impact resistance of the overall structure. This design can not only reduce the damage to the structure caused by the impact force, but also protect the internal components and extend the service life of the structure.

[0020] (2) In the present invention, the support assembly includes a pivot seat and a connecting plate arranged between the pivot seats. The pivot seat serves as a rotation support point, allowing the connecting plate to move within a certain range to adapt to different stress conditions. The outward expansion buffer rod is rotatably arranged on the pivot seat, and can expand outward when subjected to external force, thereby providing a buffering effect. The reinforcing plate is arranged at the upper and lower ends of the first side support plate and the second side support plate to enhance the stability and strength of the entire structure. The first spring is arranged on the reinforcing plate to provide elastic support, allowing the support assembly to return to its original position after being subjected to force. The support member is rotatably connected to the reinforcing plate. This design allows the outward expansion buffer rod to have enough space for buffering when it is impacted, and at the same time after the impact. It can be restored to its initial position through the elastic force of the first spring. When an external force acts on the tilting plate, the outward-expanding buffer rod in the support assembly will respond first and absorb the impact force by rotating. The elastic action of the first spring cooperates with the rotation of the support member, so that the structure can respond quickly and absorb the impact energy, reducing damage to the tilting plate. The entire structure achieves reinforcement and buffering of the tilting plate through the synergy of various components. The reinforcement plate provides additional support force, while the combination of the first spring and the support member provides dynamic buffering capacity, so that the structure can remain stable when facing impact, while reducing the impact of the impact on the entire system. In summary, the structure effectively improves the lateral compressive strength of the tilting plate and the buffering effect of the entire structure through carefully designed support components and buffering mechanisms, enabling it to better withstand and disperse external forces and protect the main structure from damage.

[0021] (3) In the present invention, the pull rod in the sliding pressure relief member serves as the main force transmission element, and one end of the pull rod is connected to a claw hook. The claw hook is used to grasp or release the pull rod when a force is applied to it, thereby controlling the opening and closing state of the pressure relief member. The second spring connected to the claw hook provides elastic force to ensure that the claw hook can quickly respond to changes in external force and quickly return to the initial position after pressure relief to prepare for the next pressure relief action. The shaft rods are arranged on both sides of the top plate, and the rotating shafts at both ends of the shaft rods allow the shaft rods to rotate around the rotating shafts. This design enables the pressure relief part to respond to external forces in multiple directions, increasing the flexibility and adaptability of the pressure relief part. The inclined pressure plate is set on the outer wall of the rotating shaft, and its design helps to transmit force to the pulley. The pulley corresponds to several sliding grooves on the inner cabinet, so that the inclined pressure plate can slide left and right in the slide groove to achieve pressure relief. During the pressure relief process, when pressure relief is required, the pull rod is acted upon by force, and the second spring is driven by the claw hook to rotate the inclined pressure plate along the rotating shaft, thereby pushing the pulley to slide in the slide groove. The sliding of the pulley causes the pressure relief part to move to the left and right sides, thereby opening the pressure relief channel and achieving pressure relief. After the pressure relief is completed, the elastic force of the second spring acts on the claw hook to reset it, thereby driving the pull rod and the inclined pressure plate back to the initial position, closing the pressure relief channel, and preparing for the next pressure relief action. The design of the entire sliding pressure relief part cleverly utilizes the lever principle, the elastic action of the spring, and the sliding mechanism to achieve the purpose of accurately controlling the pressure relief process. This design not only improves the reliability of pressure relief, but also reduces costs and improves pressure relief efficiency by reducing additional transmission parts.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0044] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] Embodiment 1

[0046] Reference Figure 1-7 A frequency conversion cabinet with a multi-layer support mechanism includes a cabinet body 1, a cabinet door 2 arranged on the cabinet body 1, and an inner cabinet body 5 arranged inside the cabinet body 1.

[0047] The first supporting mechanism 3 is arranged on the top of the cabinet 1 and is used to protect the cabinet 1. The first supporting mechanism 3 includes an upper supporting plate 30 and an inclined plate 31. An anti-bending component is arranged between the upper supporting plate 30 and the inclined plate 31 and is used to improve the side compressive strength of the inclined plate 31.

[0048] Among them, the anti-bending component includes a plurality of connecting plates 32 arranged on the edges of both sides of the upper support plate 30, one end of the connecting plate 32 is provided with an inclined rod 33 inclined toward the upper right, a hollow groove 34 arranged on the inclined plate 31 for connecting with the inclined rod 33, a first ring 35 and a second ring 36 arranged at one end of the inclined rod 33, a hidden groove 37 formed on the outer wall of the inclined rod 33, a force frame 38 arranged in the hidden groove 37, a buffer composed of a first plate 39, a second plate 310 and a rubber member 311 arranged in the hidden groove 37, and the buffer is connected to the force frame 38 to limit the movement of the first ring 35 and improve the connectivity between the inclined rod 33 and the hollow groove 34.

[0049] Among them, the opening size of the hollow groove 34 is slightly larger than the outer diameter of the inclined rod 33. When the inclined plate 31 is subjected to force, it is ensured that the inclined plate 31 can be movably connected to the inclined rod 33 through the hollow groove 34, which matches the characteristics of the subsequent buffer part, thereby ensuring that the connection node position of the inclined plate 31 can have a certain buffering and pressure resistance effect, thereby improving the usability of the overall structure.

[0050] Furthermore, a plurality of rubber members 311 are tilted and arranged between the first plate 39 and the second plate 310 in sequence. Furthermore, a plurality of tilted rubber members 311 have a tilt angle A, wherein 15 degrees ≤ A ≤ 20 degrees. In one embodiment, in order to enable the rubber member 311 to reduce shock while maintaining overall stability, A is approximately 15 degrees. When the tilt angle A is too large, the force on the rubber member 311 may be uneven, affecting the shock-absorbing effect; when the tilt angle A is too small, the tilt support effect may not be achieved.

[0051] Therefore, when the rubber member 311 is tilted, its force distribution will change, so that it can provide additional support and cushioning. Since the rubber material has unique viscoelastic properties, it can effectively absorb and dissipate impact energy. When impacted, the tilt angle of the rubber member 311 helps to disperse and redistribute the impact force, thereby reducing the force directly acting on the first ring 35, thereby improving the seismic performance of the structure. When the rubber member 311 is stressed, in the tilted state, in addition to the force in the vertical direction, the rubber member 311 will also be subjected to a component force along the tilt direction. This component force helps to reduce the direct contact with the first ring 35, thereby reducing the direct stress caused by the impact. Furthermore, the tilted setting can increase the contact area between the rubber member and the first plate 39, thereby improving the cushioning effect. The hysteresis and internal friction characteristics of the rubber are usually expressed by the loss factor. The larger the loss factor, the more significant the damping and heat generation of the rubber, and the more obvious the shock absorption effect.

[0052] It should be noted that in the actual setting process, the best tilt angle can be determined through experiments and calculations to maximize the shock absorption effect. At the same time, a rubber material with high damping performance, such as butyl rubber, is selected to improve the shock absorption effect. Furthermore, the thickness and size of the rubber member 311, as well as the distribution, also need to be considered. Therefore, the specific implementation needs to be selected and set according to the situation.

[0053] The connecting mechanism includes a first side supporting plate 3-0 and a second side supporting plate 3-00. The front end surfaces of the first side supporting plate 3-0 and the second side supporting plate 3-00 are both provided with a supporting assembly for supporting the inclined plate 31, so as to further improve the lateral compressive strength of the inclined plate 31; wherein the supporting assembly includes a pivot seat 3-1, a connecting plate 3-3 arranged between the pivot seats 3-1, an outward expansion buffer rod 3-2 rotatably arranged on the pivot seat 3-1, a reinforcing plate 3-4 arranged at the upper and lower ends of the first side supporting plate 3-0 and the second side supporting plate 3-00, a first spring 3-5 arranged on the reinforcing plate 3-4, and a supporting member 3-6 arranged at one end of the first spring 3-5. wherein the supporting member 3-6 is rotatably connected to the reinforcing plate 3-4, so that the outward expansion buffer rod 3-2 has sufficient buffer space, thereby improving the buffering effect of the entire structure.

[0054] In actual use, if the tilting plate 31 only plays a protective role by means of a buffer member arranged at the connection node, the tilting plate 31 may fail directly when subjected to force and indirectly damage the cabinet 1. Therefore, in this case, a support assembly for supporting the tilting plate 31 is arranged on the side of the cabinet 1. The support assembly includes a rotatable outward-expanding buffer rod 3-2, a reinforcing plate 3-4 used in conjunction with the outward-expanding buffer rod 3-2, a first spring 3-5 and a support member 3-6, which can further ensure that the tilting plate 31 will not directly contact the cabinet 1 when subjected to impact, thereby reducing the damage to the cabinet 1 caused by the impact force.

[0055] The second supporting mechanism 7 is arranged at the top of the inner cabinet 5, and is used to improve the compressive strength of the top of the cabinet 1; the second supporting mechanism 7 includes a top plate 70, an intermediate plate 74 arranged on the top plate 70, and sliding pressure relief parts symmetrically arranged on both sides of the intermediate plate 74, which are used to offset the force on the top of the cabinet 1; and also includes a third supporting mechanism 8 arranged on the intermediate plate 74, which is used to support the sliding pressure relief part.

[0056] Among them, the sliding pressure relief component includes a pull rod 75, a claw hook 76 arranged at one end of the pull rod 75, a second spring 77 connected to the claw hook 76, an axle rods arranged on both sides of the top plate 70, a rotating shaft 71 arranged at both ends of the axle rod, an inclined pressure plate 72 arranged on the outer wall of the rotating shaft 71, and a pulley 73 arranged at one end of the inclined pressure plate 72. The pulley 73 corresponds to a plurality of slide grooves 6 arranged on the inner cabinet body 5, and slides to the left and right sides to relieve pressure.

[0057] The third supporting mechanism 8 includes an impact column 80, a first connecting plate 81, a second force-bearing rod 85, a second connecting plate 82, a force column 83 and a first force-bearing rod 84 which are arranged in sequence below the impact column 80, the second force-bearing rod 85 is located between the first connecting plate 81 and the second connecting plate 82, the force column 83 is located in the middle of the lower end of the second connecting plate 82, and the first force-bearing rod 84 is located around the lower end of the second connecting plate 82.

[0058] When the structure is assembled in place, when the top of the cabinet 1 is subjected to force, since the first supporting mechanism 3 has eliminated part of the force in advance, the force transmitted from the top of the cabinet 1 is reduced. Then, the top plate 70 will be subjected to the residual force, the shaft 71 will rotate toward the outside of the shaft, the inclined pressure plate 72 will be pressed down, and the pulley 73 will slide outward along the slide groove 6, thereby driving the top plate 70 to be pressed down. At the same time, since three of the several shafts 71 are connected to the second spring 77, and the second spring 77 is connected to the pull rod 75 and the claw hook 76, the shaft 71 rotates at the same time. When the shaft rod and the three rotating shafts 71 are rotated outward, the second spring 77 is stretched in the direction of the pulley 73 to ensure that the entire structure can be stretched and reset by utilizing the characteristics of the second spring 77, and the middle plate 74 on the downwardly pressed top plate 70 is in contact with the gray impact column 80. The impact column 80 is made of rubber and also has certain deformation characteristics. The force is gradually transmitted to the force-bearing column 83 and the first force-bearing rod 84 to disperse the force, thereby maximizing the protection of the cabinet body 1 from damage and preventing the inner cabinet body 5 from damage, thereby improving the protection of the entire frequency conversion cabinet.

[0059] Furthermore, when the top plate 70 transfers the force to the impact column 80, the impact column 80 is pre-stressed and then transferred to the first connecting plate 81, the second force-bearing rod 85, the second connecting plate 82, the first force-bearing rod 84 and the force-bearing column 83. The force is gradually decomposed by the various components of the rubber material. At the same time, the impact column 80 is arranged in the middle of the top end of the first connecting plate 81, the two second force-bearing rods 85 are arranged in parallel between the first connecting plate 81 and the second connecting plate 82, and the force column 83 is arranged in the middle of the bottom end of the second connecting plate 82. This arrangement can effectively decompose the force, and a part of the energy is absorbed in each step, thereby reducing the final force acting on each component. At the same time, the first force-bearing rods 84 are symmetrically arranged around the bottom of the second connecting plate 82. This symmetrical layout helps to evenly disperse the impact force and reduce local stress concentration.

[0060] The present invention also includes a method for using a frequency conversion cabinet having a multi-layer support mechanism, as follows:

[0061] S1. Prepare the accessories of each mechanism and start assembly after preparation;

[0062] S2. The upper supporting plate 30 and the inclined plate 31 in the first supporting mechanism 3 are connected through the connecting plate 32 and the inclined rod 33. The connecting plate 32 is fixed on both sides of the upper supporting plate 30. The two sides of the upper supporting plate 30 are longer than the cabinet 1, so as to provide a reserved space for the subsequent anti-buffering of the inclined plate 31. When the inclined rod 33 passes through the hollow groove 34, the first ring 35 and the second ring 36 are fixed on the inclined rod 33 in sequence, and the force frame 38 in the hidden groove 37 on the inclined rod 33 abuts against the first ring 35, and the first ring 35 is limited by the buffer, thereby completing the protection of the top of the cabinet 1;

[0063] S3, when the inclined plate 31 is pressed downward, the end connected to the inclined rod 33 will move outward, and the rubber member 311 between the first plate 39 and the second plate 310 in the buffer member can buffer the force of the force frame 38, thereby resisting the first ring 35;

[0064] S4. When the top protection of the cabinet 1 is completed, the inclined plate 31 is still in contact with the first side support plate 3-0 and the second side support plate 3-00, and the outward expansion buffer rod 3-2 on the pivot seat 3-1 supports the inclined plate 31. When the inclined plate 31 is subjected to lateral force, the inclined plate 31 squeezes the outward expansion buffer rod 3-2, and the outward expansion buffer rod 3-2 contacts the support member 3-6, and the support member 3-6 is rotatably connected to the reinforcing plate 3-4. Therefore, when the outward expansion buffer rod 3-2 is pressed against the support member 3-6, the first spring 3-5 arranged between the reinforcing plate 3-4 and the support member 3-6 offsets the applied force of the outward expansion buffer rod 3-2, thereby completing the side protection of the cabinet 1;

[0065] S5. After the side protection of the cabinet 1 is completed, the second supporting mechanism 7 installed on the top of the inner cabinet 5 further improves the protection strength of the cabinet 1. When subjected to force, the top plate 70 is pre-stressed, the rotating shaft 71, the inclined pressure plate 72 and the pulley 73 will move to both sides, and the pulley 73 will slide in the slide groove 6. When sliding to both sides, the pull rod 75 and the claw hook 76 will use the first spring 3-5 to pull three of the several rotating shafts 71, thereby making the force on the top plate 70 weakened by sliding and pulling by several first springs 3-5, thereby achieving a pressure relief effect;

[0066] S6. After the pressure is released, the impact column 80 in the third impact mechanism 8 connected to the middle plate 74 can play a supporting role and further achieve the characteristic of reducing the impact.

[0067] S7. Through the above buffering and pressure relief methods, the frequency converter cabinet can be supported and protected.

[0068] Embodiment 2

[0069] Reference Figure 8 The difference between this embodiment and the first embodiment is that a first damping particle 86 is arranged between the first connecting plate 81 and the second connecting plate 82 .

[0070] In this embodiment, the first damping particles 86 are made of steel balls, and the diameter of the steel balls is about 10 mm. The steel balls have high density and good wear resistance, and provide good energy consumption effects.

[0071] Furthermore, the filling rate of the first damping particles 86 is about 80%, which can ensure that there are sufficient gaps between the first damping particles 86 for movement while maximizing the energy dissipation effect.

[0072] Embodiment 3

[0073] Reference Fig. 9 The difference between this embodiment and the first embodiment is that a second damping particle 860 is further arranged between the first connecting plate 81 and the second connecting plate 82 .

[0074] In this embodiment, the second damping particles 860 are made of rubber or polyurethane, and the diameter of the rubber second damping particles 860 is about 5 mm. The viscoelastic property of rubber helps to absorb and dissipate vibration energy.

[0075] Furthermore, the filling rate of the second damping particles 860 is about 90%, which can maximize the damping effect.

[0076] Embodiment 4

[0077] A three-layer structure may be provided between the first connecting plate 81 and the second connecting plate 82; the bottom layer of the three-layer structure may be filled with heavier metal particles, such as lead or steel particles, to provide preliminary energy dissipation and impact absorption, and further, the metal particles also have a certain heat dissipation function, which can achieve auxiliary heat dissipation; the middle layer of the three-layer structure may use a mixed layer of metal and polymer particles to balance the energy dissipation and shock absorption effect; the top layer of the three-layer structure may use lighter polymer particles, such as polyurethane or rubber, to provide final energy dissipation and shock absorption. Since heavier metal particles have a better shock absorption effect on low-frequency impacts, and lighter polymer particles provide better shock absorption effect under high-frequency impacts, and the two are combined to achieve vibration reduction of mid-frequency impacts, it can greatly adapt to the complex impact frequency bands in mines.

[0078] Embodiment 5

[0079] Reference Figure 10-11, the difference between this embodiment and the third supporting mechanism 80 in the first embodiment is that the middle plate 74 further includes a fourth supporting mechanism 9, the fourth supporting mechanism 9 includes a first mounting plate 90 and a second mounting plate 91, the first mounting plate 90 is provided with an outer frame 900, a supporting portion 910 provided on the second mounting plate 91, a cavity filled with fourth damping particles 911 is formed inside the supporting portion 910, a transverse support plate 913 provided in the cavity and placed above the fourth damping particles 911, a third spring 914 provided on the top of the transverse support plate 913, and the third The spring 914 is connected to the outer frame 900, and the outer frame 900 is covered on the top of the support part 910, and a number of inflatable rubbers 901 are arranged at equal intervals between the outer frame 900 and the support part 910; an installation cavity for filling the third damping particles 903 is also formed between the outer frame 900 and the support part 910, and fixing plates 902 are arranged at both ends of the outer frame 900 connected to the first mounting plate 90, and an installation seam is formed between the first mounting plate 90 and the support part 910, and the installation seam is filled with foam gel 10 for connecting the first mounting plate 90 and the support part 910.

[0080] When the surplus force consumed by the top plate 70 is transmitted to the outer frame 900 and the support part 910 on the first mounting plate 90 and the second mounting plate 91, the force is first transmitted to the outer frame 900, which plays a role in preliminarily dispersing the impact force and reducing the force directly transmitted to the support part 910. The support part 910 is filled with fourth damping particles 911. When these particles are subjected to impact force, they dissipate energy through internal friction and collision to reduce the transmission of impact force. The transverse support plate 913 is located above the fourth damping particle 911, and the third spring 914 on the top thereof When impacted, elastic deformation occurs to absorb the impact and reduce the direct impact on the structure. The inflatable rubber 901 disposed between the outer frame 900 and the support portion 910 can be compressed when impacted, and absorbs the impact through its own elastic deformation to reduce the impact on the structure. The third damping particles 903 are filled in the installation cavity between the outer frame 900 and the support portion 910, and work together with the inflatable rubber 901 to further absorb and dissipate the impact. The fixing plate 902 is used to connect the outer frame 900 and the first installation plate 90 to enhance the stability of the structure. The foam gel 10 filled in the installation seam plays a role of sealing and buffering, preventing the impact from being transmitted through the installation seam, and also plays a role of stabilizing the structure. The entire structure is designed as a collaborative system, and each component absorbs and disperses the impact at different stages. The outer frame 900, the support portion 910, the damping particles, the inflatable rubber 901 and the foam gel 10 work together to form a multi-level impact reduction system.
