Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a rodent-proof pipe, an air suspension system, and a vehicle. Background Technology

[0002] In a vehicle's air suspension system, the air suspension piping is a critical component ensuring the system's proper functioning. However, rodent damage to the vehicle chassis is a common cause of air suspension piping failure. Traditional air suspension piping is often made of materials like rubber or nylon, whose fragility allows rodents to easily gnaw and damage the piping, leading to air leaks and suspension failure. This damage not only affects the vehicle's normal operation but also incurs high repair costs.

[0003] Existing rodent control measures, such as wrapping pipes with metal sleeves, can prevent rodent gnawing to some extent, but they have significant drawbacks, including heavy weight, poor flexibility, and impaired pipe deformation compensation. Furthermore, current protective measures are mostly passive, relying solely on physical barriers to deter rodents. This passive approach cannot actively repel rodents, and over time, rodents may find ways to bypass these barriers, rendering them ineffective. Summary of the Invention

[0004] In view of this, the present invention provides a rodent-proof pipe, an air suspension system, and a vehicle to solve the problem that the air suspension pipe cannot actively repel rodents and is damaged by being chewed.

[0005] In a first aspect, the present invention provides a rodent-proof conduit, comprising:

[0006] An airtight layer has internal channels that are interconnected within it, and the airtight layer is designed to ensure the airtightness of the internal channels.

[0007] A rodent repellent slow-release layer is placed on the outside of the airtight layer. The rodent repellent slow-release layer contains rodent repellent ingredients that are suitable for volatilization into the air.

[0008] Beneficial Effects: The rodent-proof pipeline provided in the embodiments of the present invention employs a multi-layered composite pipe wall. By setting a rodent repellent slow-release layer outside the airtight layer, the rodent repellent slow-release layer contains rodent-repellent components suitable for volatilization into the air, thereby actively releasing the rodent-repellent components to effectively repel rodents, providing active protection and reducing rodent damage to the pipeline. Due to the continuous volatilization of the rodent-repellent components, a long-term effective protective barrier can be formed, avoiding the problem of traditional physical barriers failing at any time.

[0009] In one optional implementation, the rodent-proof conduit further includes:

[0010] A protective layer is placed between the airtight layer and the rodent repellent slow-release layer, and the protective layer is stronger than the airtight layer.

[0011] Beneficial effects: The protective layer enhances the overall structural strength of the rodent-proof pipeline, effectively resisting external physical impacts and rodent gnawing. This better ensures the integrity of the airtight layer, guarantees the airtightness of the internal channels, and extends the service life of the rodent-proof pipeline. The combination of the protective layer and the rodent repellent slow-release layer achieves a combined physical and chemical method of rodent prevention, effectively improving the rodent-proof effect, reducing rodent damage to the pipeline, and solving the rodent problem at its source.

[0012] In one optional implementation, the rodent-proof conduit further includes:

[0013] The rodent repellent base layer is wrapped around the outside of the airtight layer;

[0014] The rodent repellent sustained-release layer comprises multiple capsule particles, the interior of which is adapted to be filled with rodent repellent ingredients; the capsule particles are adapted to be embedded in the rodent repellent base layer.

[0015] Beneficial effects: This facilitates the integration of rodent-repellent ingredients with rodent-proof tubing. The capsule-shaped structure effectively protects the internal rodent-repellent ingredients, preventing them from becoming ineffective or being released too quickly due to direct contact with the external environment. This helps ensure that the rodent-repellent ingredients can function stably and continuously when needed.

[0016] In one alternative implementation, the capsule wall material of the capsule particles includes a temperature-sensitive material.

[0017] Beneficial effects: By using a temperature-sensitive material for the capsule walls, the release rate of the rodent-repellent ingredients can be adjusted according to changes in ambient temperature. Release is accelerated in warmer seasons to enhance the rodent-repellent effect, while release is slowed in colder seasons to extend the lifespan of the ingredients. This allows for more precise targeting of rodent activity patterns and improves the protective capabilities of rodent-proof systems. It ensures effective rodent repellency under different temperature conditions, enhancing the adaptability of rodent-proof systems.

[0018] In one alternative embodiment, the temperature-sensitive material comprises poly(N-isopropylacrylamide).

[0019] Beneficial Effects: Poly(N-isopropylacrylamide) exhibits significant temperature sensitivity; its molecular structure undergoes a phase transition within a specific temperature range, thereby regulating the permeability of the capsule wall. As temperature increases, the molecular chains expand, increasing the pore size of the capsule wall and accelerating the release of the rodent-repelling component. Conversely, as temperature decreases, the molecular chains contract, reducing the pore size and slowing the release rate. By employing a temperature-dependent regulatory mechanism, not only is the effective period of the rodent-repelling component extended, but precise control over peak rodent activity periods is also achieved.

[0020] In one alternative implementation, the rodent repellent ingredient includes menthol and / or capsaicin derivatives.

[0021] Beneficial effects: Menthol and capsaicin derivatives have strong repellent effects, effectively interfering with rodents' sense of smell and taste, reducing their willingness to forage and move. Through the regulation of temperature-sensitive materials, the rodent-repellent ingredients are precisely released at different temperatures, maximizing the rodent-repellent effect while avoiding unnecessary waste, further improving the environmental friendliness and economy of rodent-proof pipelines.

[0022] In one alternative implementation, the rodent repellent base layer is made of nylon 12.

[0023] In one optional implementation, the rodent-proof conduit further includes:

[0024] Rodent repellent base layer;

[0025] The rodent repellent sustained-release layer consists of a base layer and multiple capsule particles embedded in the base layer, with the capsule particles being suitable for filling with rodent repellent ingredients;

[0026] The base layer covers the outside of the rodent repellent base layer, and the base layer and the rodent repellent base layer are detachably connected.

[0027] Beneficial effects: By detachably connecting the base layer to the rodent repellent base layer, the rodent repellent ingredients can be flexibly replaced and maintained, extending the service life of the rodent repellent effect.

[0028] In a second aspect, the present invention also provides an air suspension system, comprising:

[0029] The compressor and the rodent-proof piping connected to the compressor, as described above.

[0030] Since the air suspension system includes rodent-proof tubing, which has the same effect as rodent-proof tubing, it will not be elaborated on here.

[0031] Thirdly, the present invention also provides a vehicle, including a vehicle body and an air suspension system as described above disposed within the vehicle body.

[0032] Since the vehicle includes rodent-proof tubing, which has the same effect as rodent-proof tubing, it will not be elaborated further here. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0044] According to an embodiment of the present invention, in one aspect, a rodent-proof conduit is provided, comprising:

[0045] An airtight layer 2 has an internal channel 1 that runs through it, and the airtight layer 2 is suitable for ensuring the airtightness of the internal channel 1.

[0046] The rodent repellent slow-release layer 5 is disposed outside the airtight layer 2. The rodent repellent slow-release layer 5 contains rodent repellent ingredients that are suitable for volatilization into the air.

[0047] The rodent-proof piping in this embodiment adopts a multi-layer composite pipe wall.

[0048] Among them, the airtight layer 2 is the innermost structure, and an internal channel 1 is formed through the airtight layer 2. The internal channel 1 is suitable for the flow of a medium, such as a gas or liquid medium. The airtight layer 2 is suitable for ensuring the airtightness of the internal channel 1, ensuring that the medium does not leak during transmission.

[0049] In some embodiments, the material of the airtight layer 2 includes rubber or TPU thermoplastic polyurethane.

[0050] Furthermore, the airtight layer 2 is made of a flexible material, which ensures that the rodent-proof pipeline has good deformation compensation capabilities and dynamic flexibility. For example, it can still maintain good airtightness when the bending radius of the rodent-proof pipeline is less than or equal to 5 times the pipe diameter. When the rodent-proof pipeline is used in an air suspension system, it can adapt well to the deformation of the suspension movement.

[0051] The rodent-proof pipeline also includes a rodent repellent slow-release layer 5, which is located outside the airtight layer 2. The rodent repellent slow-release layer 5 contains rodent repellent ingredients that are suitable for volatilizing into the air, thereby actively repelling rodents and preventing them from biting the pipeline.

[0052] The rodent-proof pipeline provided in the embodiments of the present invention employs a multi-layer composite pipe wall. A rodent repellent slow-release layer 5 is installed outside the airtight layer 2. This slow-release layer 5 contains rodent-repellent components suitable for evaporation into the air, thereby actively releasing the rodent-repellent components to effectively repel rodents, providing proactive protection and reducing rodent damage to the pipeline. Due to the continuous evaporation of the rodent-repellent components, a long-term effective protective barrier can be formed, avoiding the problem of traditional physical barriers failing at any time.

[0053] The material of the airtight layer 2 is lightweight and has good flexibility, which allows the rodent-proof pipeline to adapt to various complex installation environments, such as situations with small bending radii, while maintaining airtightness, without affecting the pipeline's deformation compensation capability, and can well adapt to frequent movement deformation.

[0054] In some embodiments, the rodent-proof conduit further includes:

[0055] The rodent repellent base layer 4 is wrapped around the outside of the airtight layer 2;

[0056] The rodent repellent sustained-release layer 5 includes multiple capsule particles 51, the interior of which is adapted to be filled with rodent repellent ingredients; the capsule particles 51 are adapted to be embedded in the rodent repellent base layer 4.

[0057] The specific structural form of the rodent repellent slow-release layer 5 can be a capsule particle 51. By filling the inside of the capsule particle 51 with rodent repellent ingredients and embedding the capsule particle 51 into the rodent repellent base layer 4, it is easy to combine the rodent repellent ingredients with the rodent-proof pipeline.

[0058] By adopting a capsule-shaped structure, the rodent-repellent ingredients inside can be well protected, preventing them from becoming ineffective or being released too quickly due to direct contact with the external environment. This helps ensure that the rodent-repellent ingredients can work stably and continuously when needed.

[0059] Secondly, the capsule particles 51 are easy to process and shape and easy to embed into the rodent repellent base layer 4, thereby simplifying the production process and improving production efficiency.

[0060] Additionally, the capsule particles 51 can be evenly distributed in the rodent repellent base layer 4 to ensure the uniform release of rodent repellent ingredients and guarantee the overall protective effect of the rodent-proof pipeline.

[0061] Furthermore, the rodent-repellent ingredient can be slowly released through the capsule particles 51, extending the effective period of the rodent-repellent effect and further improving the practicality and reliability of the rodent-proof tubing. Extending its effective time reduces the inconvenience of frequently replacing or replenishing the rodent-repellent ingredient. The rodent-proof tubing of this embodiment can achieve long-term repellency, ensuring that the effective release period of the rodent-repellent ingredient is greater than or equal to 3 years.

[0062] In some embodiments, the capsule wall material of the capsule particle 51 includes a temperature-sensitive material.

[0063] Because rodents are warm-blooded animals, they need to regulate their body temperature through their external environment. Therefore, their activity patterns are temperature-dependent. In colder environments, rodents reduce activity to conserve energy. Conversely, in warmer environments, they increase their activity levels to more efficiently obtain food and perform other survival activities. Furthermore, temperature also affects the rodent reproductive cycle; breeding is generally more frequent during warmer seasons, meaning rodent populations tend to increase during these times. Therefore, temperature changes significantly impact rodent behavior patterns, activity levels, and reproductive activities.

[0064] By using a temperature-sensitive material to make the capsule wall of the capsule particles 51, the release rate of the rodent-repellent ingredients can be adjusted according to changes in ambient temperature. Release is accelerated in warmer seasons to enhance the rodent-repellent effect, while release is slowed down in colder seasons to extend the lifespan of the rodent-repellent ingredients. This allows for more precise targeting of rodent activity patterns and improves the protective capabilities of rodent-proof pipelines. It ensures effective rodent repellency under different temperature conditions, enhancing the adaptability of rodent-proof pipelines.

[0065] In this embodiment, for example, the release of the rodent-repellent component can be accelerated when the ambient temperature is >25°C.

[0066] In some embodiments, the temperature-sensitive material includes poly(N-isopropylacrylamide).

[0067] Poly(N-isopropylacrylamide) exhibits significant temperature sensitivity; its molecular structure undergoes a phase transition within a specific temperature range, thereby regulating the permeability of the capsule wall. As temperature increases, the molecular chains expand, increasing the pore size of the capsule wall and accelerating the release of the rodent-repellent component. Conversely, as temperature decreases, the molecular chains contract, reducing the pore size and slowing the release rate. By employing a temperature-dependent regulatory mechanism, not only is the effectiveness of the rodent-repellent component extended, but precise control over peak rodent activity periods is also achieved.

[0068] Additionally, temperature-sensitive materials may also include polyurethane, melamine resin, etc.

[0069] In some embodiments, the rodent repellent ingredient includes menthol and / or capsaicin derivatives.

[0070] Menthol and capsaicin derivatives have strong repellent effects, effectively interfering with rodents' sense of smell and taste, reducing their willingness to forage and move. Through the regulation of temperature-sensitive materials, the rodent-repellent ingredients are precisely released at different temperatures, maximizing the rodent-repellent effect while avoiding unnecessary waste, further improving the environmental friendliness and economy of rodent-proof pipelines.

[0071] In some embodiments, the rodent repellent base layer 4 is made of nylon 12.

[0072] Nylon 12 material has good temperature resistance and chemical stability, which can ensure that the rodent repellent base layer 4 will not deform or degrade during long-term use, further enhancing the durability and stability of the rodent-proof pipeline.

[0073] To verify the actual effectiveness of the rodent-proof conduit in this embodiment, the inventors conducted high-temperature aging and immersion tests on the rodent-proof conduit, with the following results:

[0074] In the high-temperature aging test, the ambient temperature was set at 60℃ for 10 days. The release rate of capsaicin encapsulated in the polyurethane / melamine resin capsule wall decreased by <15%, and the equivalent room temperature (25℃) sustained-release life was >8 years.

[0075] In the immersion test, the rodent-repellent tubing was immersed in a salt spray environment using a 5% NaCl solution for 30 days. The results showed that there was no significant corrosion on the surface of the rodent-repellent tubing, and the release of the rodent-repellent components was stable. The microcapsule breakage rate was <5%, and the retention rate of the rodent-repellent active ingredients was >82%.

[0076] The high-temperature aging test simulated long-term use under extreme high-temperature environments, verifying the stable release capability of the rodent-repellent ingredients at high temperatures. The immersion test simulated a high-salt and high-humidity environment, further confirming the durability of the rodent-proof pipeline under harsh conditions and the continuity of its rodent-repellent effect, ensuring reliable operation in various environments.

[0077] In addition, the inventors conducted field tests on the rodent-proof pipe in practical application scenarios. The results showed that in areas with severe rodent infestations, the frequency of rodent activity around vehicles was significantly reduced after using the pipe, with an effective control rate of over 90%, further verifying its high efficiency and practicality in real-world environments.

[0078] Field tests also revealed that the rodent-proof pipeline exhibits excellent adaptability under different seasons and climate conditions, effectively reducing rodent damage to the pipeline and significantly improving the vehicle's service life and safety performance.

[0079] In some embodiments, the rodent-proof conduit further includes:

[0080] The protective layer 3 is disposed between the airtight layer 2 and the rodent repellent slow-release layer 5, and the strength of the protective layer 3 is greater than that of the airtight layer 2.

[0081] The protective layer 3 can be wrapped around the outside of the airtight layer 2, enhancing the overall structural strength of the rodent-proof pipeline and effectively resisting external physical impacts and rodent gnawing. This better ensures the integrity of the airtight layer 2, guarantees the airtightness of the internal channel 1, and extends the service life of the rodent-proof pipeline.

[0082] The combination of protective layer 3 and rodent repellent slow-release layer 5 enables a combination of physical and chemical methods to prevent rodent gnawing, effectively improving the rodent control effect, reducing rodent damage to pipelines, and solving the rodent problem at its source.

[0083] Employing multiple protective measures, it achieves both passive rodent-proof protection and enhanced active rodent-repellent protection, further improving the comprehensive protection capabilities of rodent-proof pipelines and ensuring their long-term stable operation in complex environments, providing dual protection for vehicle safety.

[0084] In some embodiments, the protective layer 3 comprises an aramid fiber woven mesh or galvanized steel wire, the galvanized steel wire being adapted to be spirally wound around the outside of the airtight layer 2.

[0085] Aramid fiber woven mesh possesses high strength and high modulus, with a strength 5 to 6 times that of steel wire. This gives it exceptional tear and puncture resistance. When rodents attempt to gnaw on it, the aramid fiber woven mesh can resist penetration by their teeth, thus protecting its internal structure from damage. Furthermore, aramid fiber woven mesh exhibits excellent flame retardancy, chemical corrosion resistance, and thermal stability, maintaining its performance even in harsh environments. This means that in outdoor or humid environments, aramid fiber woven mesh can still effectively resist rodent gnawing, extending its service life.

[0086] Galvanized steel wire possesses high tensile strength, enabling it to withstand significant external impacts without easily deforming or breaking. This allows the galvanized steel wire to maintain structural integrity over a long period, effectively resisting rodent gnawing and damage. Furthermore, the galvanized layer effectively prevents rust and corrosion, maintaining its anti-rust and anti-corrosion effect even in humid or harsh environments. This ensures that rodent-proof netting made of galvanized steel wire retains its function for a long time, without losing its rodent-proof effect due to corrosion. The galvanized steel wire is spirally wound onto the outside of the airtight layer 2. This tight spiral winding makes it difficult for rodents such as mice to find a breakthrough point, effectively preventing them from damaging the structure. This forms a tight protective layer, enhancing the overall stability of the rodent-proof pipeline, effectively preventing rodent penetration, and ensuring the long-term safe operation of the pipeline.

[0087] In this embodiment, the protective layer 3 can withstand a biting force of greater than or equal to 500N, meeting the rodent gnawing test standard ISO1818.

[0088] As a variation, in some other embodiments, the rodent-proof conduit further includes:

[0089] Rodent repellent base layer 4;

[0090] The rodent repellent sustained-release layer 5 includes a base layer 52 and a plurality of capsule particles 51 embedded in the base layer 52, the interior of which is adapted to be filled with rodent repellent ingredients;

[0091] The base layer 52 covers the outside of the rodent repellent base layer 4, and the base layer 52 and the rodent repellent base layer 4 are detachably connected.

[0092] By detachably connecting the base layer 52 to the rodent repellent base layer 4, the rodent repellent ingredients can be flexibly replaced and maintained, extending the service life of the rodent repellent effect.

[0093] The detachable connection between the base layer 52 and the rodent repellent base layer 4 can be achieved through various methods, including hook-and-loop fastening, snap-fit ​​fastening, magnetic fastening, or zipper fastening. This greatly facilitates daily maintenance and replacement, ensuring long-term and highly effective rodent control.

[0094] According to an embodiment of the present invention, in another aspect, an air suspension system is also provided, comprising:

[0095] The compressor and the rodent-proof piping connected to the compressor, as described above.

[0096] According to an embodiment of the present invention, in another aspect, a vehicle is also provided, comprising:

[0097] The vehicle body, and the air suspension system as described above installed within the vehicle body.

[0098] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
