Technical Field
[0001] This utility model relates to the field of nylon tube structure technology, specifically a five-layer air suspension water vapor barrier nylon tube. Background Technology
[0002] Air suspension is an advanced automotive suspension system. It mainly consists of air springs, shock absorbers, and a guiding mechanism. The air spring is its core component, providing elastic support by inflating with compressed air. The air pressure can be adjusted according to different road conditions and loads, thereby changing the suspension stiffness and height to provide excellent ride comfort and stability. It effectively improves ride smoothness, reduces bumps, and can be flexibly adjusted according to different driving modes and needs, adapting to various road conditions and driving styles.
[0003] The nylon tubing in air suspension systems typically possesses high strength, wear resistance, and corrosion resistance. It is responsible for transmitting compressed air within the air suspension system, and its excellent flexibility allows it to adapt to various dynamic changes during vehicle operation. Simultaneously, the nylon tubing must maintain good sealing properties to ensure no air leakage and to maintain the normal operating pressure of the air suspension system. Special processes and materials are used in the manufacturing of nylon tubing, and it undergoes rigorous quality testing to guarantee the stable and reliable operation of the air suspension system.
[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. During use, the existing nylon tubes are often invaded by external water vapor, which causes the water vapor to enter the tube body and condense into water, thereby affecting the shock absorption effect and performance of the air suspension; 2. When the existing nylon tubes are connected and assembled with the air suspension, they often adopt a relatively complex connection method, which is difficult to operate and is prone to leakage at the connection point. Utility Model Content
[0005] The purpose of this utility model is to provide a five-layer air suspension water vapor barrier nylon tube to solve the problems mentioned in the background art, such as the intrusion of external water vapor into existing nylon tubes during use, which causes water vapor to enter the tube body and condense into water, thus affecting the shock absorption effect and performance of the air suspension. Furthermore, the connection and assembly of existing nylon tubes with the air suspension often employs a relatively complex method, which is difficult to operate and prone to leakage at the connection point. To achieve the above objective, this utility model provides the following technical solution: a five-layer air suspension water vapor barrier nylon tube, including an air suspension, one end of which is snapped with a connector, the other end of which is located at the air outlet of the tube body, the outer layer of the tube body having a wear-resistant layer, the inner wall of the wear-resistant layer having a preliminary isolation layer, the inner wall of the preliminary isolation layer having a core barrier layer, the inner wall of the core barrier layer having a buffer sealing layer, and the inner wall of the buffer sealing layer having a seepage-proof inner layer.
[0006] In a further preferred embodiment, the connector is provided with a sealing ring on the side near the air outlet end of the pipe, and the sealing ring is provided with a plurality of elastic clips on the side near the air suspension, wherein the diameter of the ring formed by the plurality of elastic clips is larger than the inner diameter of the air suspension interface.
[0007] More preferably, the connector has a magnetic suction plate on the side near the sealing ring, and the magnetic suction plate is attracted to the outer wall of the air suspension port.
[0008] More preferably, the surface of the wear-resistant layer is provided with multiple sets of diamond-shaped textures.
[0009] More preferably, the surface of the preliminary isolation layer has micropores and is made of polytetrafluoroethylene film material, the core barrier layer is made of nanocomposite nylon material, and the preliminary isolation layer and the core barrier layer are connected to each other by hot-pressing composite method.
[0010] More preferably, the surface of the buffer sealing layer is wavy.
[0011] More preferably, the inner impermeable layer is coated with a waterproof coating on the side near the buffer sealing layer, and the inner side of the waterproof coating is a silicone layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this invention, the connector can be tightly pressed against the air suspension via an elastic clip, ensuring a firm connection between the tube and the air suspension and preventing loosening or detachment during use. The sealing ring fills the gap between itself and the interface contact surface, effectively preventing leakage during gas delivery and ensuring the sealing performance of the tube. The magnetic plate further strengthens the connection between the connector and the air suspension port, making the two more firmly bonded and effectively preventing the connector from loosening due to vibration or other reasons during vehicle operation, providing an additional protection mechanism.
[0014] In this invention, the diamond-shaped texture on the surface of the wear-resistant layer reduces excessive wear on a single location, thereby extending the service life of the wear-resistant layer and the entire pipe. Furthermore, the grooves in the diamond-shaped texture alter the flow path, increasing the difficulty of penetration and providing a certain degree of obstruction. The core barrier layer and the initial isolation layer work together to form two lines of defense, further improving the barrier effect against water vapor. The buffer sealing layer better absorbs and mitigates the vibration and impact generated during vehicle operation, protecting the pipe and the entire system from excessive vibration damage. The impermeable inner layer acts as a tight barrier, directly intercepting water vapor and preventing further penetration, greatly improving the pipe's ability to block water vapor. It also provides double protection for the pipe's impermeability, maintaining the sealing performance and good impermeability of the impermeable inner layer for a long time, thus extending the pipe's service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a five-layer air suspension water vapor barrier nylon tube, including an air suspension 1, one end of the air suspension 1 is snapped with a connector 2, the other end of the connector 2 is located at the air outlet of the tube body 3, the outer layer of the tube body 3 is provided with a wear-resistant layer 4, the inner wall of the wear-resistant layer 4 is provided with a preliminary isolation layer 5, the inner wall of the preliminary isolation layer 5 is provided with a core barrier layer 6, the inner wall of the core barrier layer 6 is provided with a buffer sealing layer 7, and the inner wall of the buffer sealing layer 7 is provided with a seepage-proof inner layer 8.
[0022] In this embodiment, as Figure 1 and Figure 3As shown, a sealing ring 201 is provided on the side of the connector 2 near the air outlet end of the pipe body 3. Several elastic clips 202 are provided on the side of the sealing ring 201 near the air suspension 1. The diameter of the ring formed by the elastic clips 202 is larger than the inner diameter of the air suspension 1 interface. It should be noted that the operator can first connect the entire pipe body 3 to the air intake end of the air suspension 1 via the connector 2. Specifically, the elastic clips 202 of the connector 2 are inserted into the interface of the air suspension 1. At this time, the elastic clips 202 with larger diameters will be squeezed when inserted into the inner wall of the interface, thus contracting towards the center until the full length of the elastic clips 202 is inserted into the interface. At this point, the elastic clips 202, due to their rebound properties, will press tightly against the inner wall of the interface, thus completing the mutual clamping. During this period, the operator can again insert the sealing ring 201 located at the bottom of the elastic clips 202 into the inner wall of the interface, and due to the contact between the two, it will be squeezed, thus... The deformation caused by the elastic clip 202 fills the gap between the contact surfaces of the two components, thus completing the assembly between the tube body 3 and the air suspension 1. In actual use, the elastic clip 202 can be compressed and contracted when inserted into the air suspension 1 interface, and after insertion, it can also tightly adhere to the inner wall, achieving a tight fit with the air suspension 1. This ensures a firm connection between the tube body 3 and the air suspension 1, preventing loosening or detachment during use. The sealing ring 201 deforms due to compression after being inserted into the interface, filling the gap between itself and the interface contact surface, effectively preventing leakage during gas delivery, ensuring the sealing performance of the tube body 3, and improving the stability and reliability of the air suspension 1 system. At the same time, the operator only needs to simply insert the elastic clip 202 into the air suspension 1 interface, utilizing its elastic properties to complete the assembly. The operation is convenient, requiring no complicated tools or processes, improving installation efficiency and facilitating subsequent replacement and maintenance.
[0023] In this embodiment, as Figure 1 and Figure 3As shown, a magnetic suction plate 203 is provided on the side of the connector 2 near the sealing ring 201. The magnetic suction plate 203 is attracted to the outer wall of the air suspension 1 port. It should be noted that when the operator inserts the entire connector 2 into the air intake port of the air suspension 1, after the elastic clip 202 and the sealing ring 201 are fully inserted into the air suspension 1 port, the magnetic suction plate 203 located near the sealing ring 201 will be firmly attracted to the bottom of the air suspension 1 port due to its magnetic properties, thereby further realizing the mutual connection between the connector 2 and the air suspension 1 port. In actual use, after the elastic clip 202 and the sealing ring 201 are fully inserted, the magnetic suction plate 203 and the air intake port will be attracted to each other. The outer walls of the suspension 1 port will simultaneously adhere together, thereby further strengthening the connection between the connector 2 and the air suspension 1 port, making the two more firmly bonded. This effectively prevents the connector 2 from loosening due to vibration or other reasons during vehicle operation. Furthermore, the magnetic suction plate 203 provides an additional protection mechanism for the connection between the tube 3 and the air suspension 1. Even if the elastic clip 202 or the sealing ring 201 experiences slight loosening or sealing problems, the magnetic suction plate 203 can maintain the connection to a certain extent, reducing the risk of leakage. At the same time, the magnetic suction plate 203 makes the connector 2 more evenly stressed in the circumferential direction, avoiding deformation or damage to the connection part due to uneven local stress, and extending the service life of the connector 2 and the air suspension 1.
[0024] In this embodiment, as Figure 2 and Figure 4As shown, the surface of the wear-resistant layer 4 has multiple sets of diamond-shaped textures. It should be noted that in daily use, because the entire air suspension 1 and the tube 3 are mounted on the vehicle chassis, the tube 3 will constantly rub against sand, dust, and other materials splashed from the ground. Therefore, a wear-resistant layer 4 is provided on the outermost layer of the tube 3. This wear-resistant layer 4 can directly contact these external substances, serving as the first line of physical protection, thus preventing the tube 3 from being easily scratched or worn. The diamond-shaped textures also increase the surface roughness of the wear-resistant layer 4. Furthermore, when water vapor attempts to enter, the diamond-shaped textures act as a barrier, thus increasing the surface roughness of the wear-resistant layer 4 in actual use. The roughness of the surface allows the tube body 3 to disperse friction when in contact with sand, dust, etc., reducing excessive wear on a single location of the wear-resistant layer 4, thereby extending the service life of the wear-resistant layer 4 and the entire tube body 3. When water vapor attempts to enter the interior of the tube body 3, the grooves of the diamond texture change its flow path, thereby increasing the difficulty of its penetration and playing a certain blocking role. This helps to maintain a dry environment inside the tube body 3, thus ensuring the normal operation of the air suspension 1. At the same time, the gaps in the diamond texture of the wear-resistant layer 4 can play a role in water and dust drainage, allowing water and dust splashed on the outer wall of the tube body 3 to slide off or be shaken off more easily, reducing the accumulation on the surface of the tube body 3 and further reducing damage to the tube body 3.
[0025] In this embodiment, as Figure 2 and Figure 4As shown, the surface of the preliminary isolation layer 5 has tiny pores and is made of polytetrafluoroethylene film material. The core barrier layer 6 is made of nano-composite nylon material. The preliminary isolation layer 5 and the core barrier layer 6 are connected to each other by a hot-pressing composite method. It should be noted that when the air suspension 1 is working, water vapor in the surrounding environment will attempt to enter the tube body 3. After the external water vapor passes through the wear-resistant layer 4 and enters the tube body 3, it will first come into contact with the preliminary isolation layer 5. The preliminary isolation layer 5, through its tiny pores, acts as a sieve, blocking larger water vapor particles and some visible impurities. The water vapor that passes through the preliminary isolation layer 5 will reach the core barrier layer 6. At this time, the nano-composite nylon material of the core barrier layer 6 can greatly reduce the water vapor content in the tube body 3. In actual use, the tiny pores on the surface of the preliminary isolation layer 5 act like a sieve, effectively blocking... The primary barrier layer 5 prevents larger particles of water vapor and visible impurities from entering the interior of the tube body 3, thus preventing these impurities from clogging or damaging the air suspension system 1 and ensuring the normal operation of the system. Furthermore, the preliminary filtration by the primary barrier layer 5 reduces the chance of the core barrier layer 6 directly contacting large particles, thereby reducing the filtration burden on the core barrier layer 6, extending its service life, and making the entire barrier system more stable and durable. The core barrier layer 6 has a special structure and performance that can greatly reduce the water vapor content inside the tube body 3, maintaining a dry environment inside the tube, thus preventing problems such as component corrosion caused by excessive water vapor. At the same time, the core barrier layer 6 and the primary barrier layer 5 work together to form two lines of defense, further improving the water vapor barrier effect, ensuring that the tube body 3 can effectively prevent water vapor intrusion and guaranteeing the stable operation of the air suspension system 1 in various environments.
[0026] In this embodiment, as Figure 2 and Figure 4As shown, the surface of the buffer sealing layer 7 is wavy. It should be noted that water vapor passing through the initial isolation layer 5 and the core barrier layer 6 will reach the buffer sealing layer 7 inside the pipe body 3. During use, the buffer sealing layer 7 can mitigate vibrations caused by vehicle bumps or equipment operation. Its wavy surface absorbs these vibration impacts, thus providing a buffering effect. Furthermore, the buffer sealing layer 7 also provides auxiliary sealing. In actual use, the wavy surface of the buffer sealing layer 7 increases its deformation space, allowing for better absorption and mitigation of vibration impacts when the vehicle encounters bumps or equipment operates, effectively reducing... This reduces the amount of vibration energy transmitted to the inside of the tube body 3 and other components, protecting the tube body 3 and the entire system from damage caused by excessive vibration. Furthermore, the wave-shaped structure allows it to better conform to adjacent components under pressure, forming a tighter seal and preventing further water vapor penetration. This enhances the overall sealing performance of the tube body 3, ensuring that the air suspension 1 maintains a good sealing state under different operating conditions and reducing the impact of water vapor on the system. At the same time, the wave-shaped design allows the buffer sealing layer 7 to distribute stress to more areas, avoiding material fatigue or damage caused by local stress concentration. This enables the buffer sealing layer 7 to evenly bear various forces, further improving its buffering and sealing effects.
[0027] In this embodiment, as Figure 2 and Figure 4As shown, the inner impermeable layer 8 is coated with a waterproof coating on the side near the buffer sealing layer 7, and the inner side of the waterproof coating is a silicone layer. It should be noted that after passing through the buffer sealing layer 7, only a small amount of water vapor will reach the inner impermeable layer 8. This water vapor will be directly intercepted outside the inner impermeable layer 8 upon contact with the waterproof coating. The sealing layer, due to its sealing performance, acts as a final barrier, thus providing a double layer of protection for the water vapor barrier function of the entire inner impermeable layer 8, thereby perfecting the impermeability system of the entire pipe body 3. In actual use, when a very small amount of water vapor passes through the buffer sealing layer 7 and reaches the inner impermeable layer 8, its waterproof coating can act as a tight barrier, directly intercepting this water vapor outside the inner impermeable layer 8, preventing further penetration, and ensuring the safety of the pipe body 3. The dry internal environment greatly enhances the water vapor barrier capability of the pipe body 3. Even in the event of minute leaks in other layers, its waterproof coating can effectively prevent water vapor from passing through, significantly increasing the reliability and stability of the anti-seepage inner layer 8. The silicone layer, with its excellent sealing performance, acts as the final barrier, further preventing water vapor intrusion. Even if a small amount of water vapor breaks through the waterproof coating, the silicone layer can block it with a high probability, providing double protection for the anti-seepage function of the pipe body 3. At the same time, the silicone layer has excellent chemical stability and is not prone to chemical reactions with water vapor or other substances that may come into contact with it, thus maintaining the sealing performance of the anti-seepage inner layer 8 for a long time. This ensures that the pipe body 3 always has a good anti-seepage effect during long-term use and extends the service life of the pipe body 3.
[0028] The usage and advantages of this utility model: The five-layer air suspension water vapor barrier nylon tube operates as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the operator can first connect the entire pipe body 3 to the air intake end of the air suspension 1 via connector 2. Specifically, the elastic clip 202 of connector 2 is inserted into the interface of the air suspension 1. At this time, the elastic clip 202 with a larger circumference will be squeezed when inserted into the inner wall of the interface, thus contracting towards the center until the full length of the elastic clip 202 is inserted into the interface. At this point, due to its rebound property, the elastic clip 202 will press tightly against the inner wall of the interface, thus completing the mutual clamping. During this period, the operator can again insert the sealing ring 201 located at the bottom of the elastic clip 202 into the inner wall of the interface, and due to the contact between the two, it will be squeezed, thus causing deformation. This allows the gap between the contact surfaces of the two components to be filled. After the elastic clip 202 and the sealing ring 201 are fully inserted into the port of the air suspension 1, the magnetic plate 203 located near the sealing ring 201 will be firmly attracted to the bottom of the air suspension 1 port due to its magnetic properties, further achieving the connection between the connector 2 and the air suspension 1 port. In daily use, since the entire air suspension 1 and the tube 3 are installed on the vehicle chassis, the tube 3 will continuously rub against sand, dust, and other substances splashed from the ground. The wear-resistant layer 4 on the outermost layer of the tube 3 can directly contact these external substances, thus protecting the tube 3. The wear-resistant layer 4 is not easily scratched or worn by external substances. The diamond-shaped texture on its surface increases its roughness, and the tiny grooves between the diamond patterns can trap some moisture, further reducing the possibility of moisture penetration. External moisture passing through the wear-resistant layer 4 into the tube body 3 first contacts the preliminary isolation layer 5. This layer, with its tiny pores, acts as a sieve, blocking larger moisture particles and visible impurities. The moisture passing through the preliminary isolation layer 5 then reaches the core barrier layer 6. Here, the nano-composite nylon material of the core barrier layer 6 significantly reduces the amount of water vapor inside the tube body 3. The combined water vapor will reach the buffer sealing layer 7. Due to its auxiliary sealing function, it can further block the water vapor. The wavy design on its surface can mitigate the vibration and impact generated by vehicle bumps or equipment operation, thus playing a buffering role. Finally, after passing through the buffer sealing layer 7, only a small part of the water vapor will reach the seepage-proof inner layer 8. This part of the water vapor will be directly intercepted outside the seepage-proof inner layer 8 when it comes into contact with the waterproof coating. The sealing layer, due to its sealing performance, can act as the final barrier, thus adding a double layer of protection to the water vapor blocking function of the entire seepage-proof inner layer 8, thereby perfecting the seepage-proof system of the entire pipe body 3.
