Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a novel universal pressure pipeline for automobiles. Background Technology

[0002] When military transport vehicles perform important tasks such as training, emergency delivery and daily duties, they need to traverse harsh environments such as high altitude, low air pressure, low oxygen content, strong ultraviolet radiation and large temperature difference. They also need to withstand various extreme weather conditions. Under such complex conditions, the various components of the vehicle are continuously subjected to multiple stresses. Among them, the engine antifreeze "U"-shaped return pipe is one of the key vulnerable components.

[0003] However, the tensile properties of the currently used engine antifreeze "U"-shaped return hose gradually deteriorate under long-term environmental corrosion and the effects of time. During routine maintenance and cab rollover, the "U"-shaped return hose is subjected to additional pressure and normal tension, coupled with the effects of thermal expansion and contraction, making it extremely prone to rupture. A single rupture can result in a leakage of up to 12 kg of antifreeze. Furthermore, the continuous pressure from the vehicle's long-term operation further increases the risk of leakage during deployment, leading to a significant reduction in its service life and frequent malfunctions. Each vehicle experiencing a return hose rupture not only incurs economic losses but also requires time for replacement and refilling. In wartime, this not only occupies valuable maintenance and repair resources and disperses combat equipment repair forces, reducing the effectiveness of operational deployment support, but may even delay combat opportunities, posing a significant safety hazard to combat mission deployment support. In addition, to address the risk of return hose rupture, spare parts and antifreeze must be carried in advance, which undoubtedly increases the workload of material warehousing and occupies a large amount of material storage space. Therefore, a new type of universal pressure pipeline for vehicles is needed. Utility Model Content

[0004] The purpose of this invention is to provide a novel universal pressure pipeline for vehicles to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel universal pressure pipeline for vehicles, comprising a flexible pipeline, wherein each end of the flexible pipeline is connected to a connecting end block, and the end of the connecting end block away from the flexible pipeline is connected to a connecting sleeve. The flexible pipeline comprises an inner layer and an outer layer, wherein the outer layer is disposed outside the inner layer, and the outer layer is made of aramid fiber material. (The inner layer is smooth, which can reduce liquid resistance, and the outer layer may also be made of polyester material, which can improve tensile strength.)

[0006] Preferably, the end of the connecting sleeve away from the connecting end block is connected to a connecting component. The connecting component adopts a ball-head universal structure to enable free rotation in three-dimensional space during the transmission of pressure medium, so as to effectively adapt to changes in pipeline angle under conditions such as vehicle driving and cab tilting, and avoid stress concentration caused by hard bending.

[0007] Preferably, the connecting assembly includes a connector ball core connected to one end of the connecting sleeve, a connector body is provided outside the connector ball core, a cavity is provided inside the connector body, a clamping connector is provided inside the cavity, one end of the clamping connector is sleeved outside the connector ball core, a first flow guiding cavity is provided inside the connector ball core, and a second flow guiding cavity communicating with the first flow guiding cavity is provided inside the clamping connector.

[0008] Preferably, the connecting assembly further includes a first retaining ring and a second retaining ring fixedly connected to the inner surface wall of the cavity. The first retaining ring and the second retaining ring are located on the outer side of the connector ball core, and the second retaining ring is located at one end of the compression connector.

[0009] Preferably, the end of the compression connector away from the connector ball core is fixedly connected to a mounting block, and the mounting block is provided with multiple connection holes at equal intervals (connecting the mounting block at one end of the universal pressure pipeline to the engine water outlet, and the mounting block at the other end to the water tank return port).

[0010] Through the above technical solution:

[0011] In use, the flexible conduit with straight sections and slight bends replaces the original U-shaped hard bend (the total length of the flexible conduit is longer than the original U-shaped conduit, allowing for stretching allowance). With its high flexibility and elastic deformation capacity, it effectively absorbs bending and tensile stress, resists embrittlement in high temperatures, deformation under low pressure, UV aging, and thermal expansion and contraction impacts, completely solving the problem of leakage from U-shaped return water pipe ruptures. Combined with the ball-head universal joint connection assembly, it can flexibly adapt to changes in pipe angles under complex vehicle operating conditions, further dispersing stress. Compared to traditional conduits, the new conduit... The stability and durability of the pipeline are significantly improved, greatly reducing the frequency of maintenance, lowering costs and time losses. In addition, under extreme conditions of military transport, it can ensure stable coolant transmission, avoid engine failure, improve delivery timeliness, reduce oil consumption, and save wartime maintenance resources. Furthermore, due to its excellent performance, it can replace various pipeline processes, achieving "one pipe for multiple uses." It not only effectively enhances combat support capabilities in the military field, but also improves work efficiency, saves energy, and reduces environmental pollution caused by equipment failures in other industries, demonstrating strong adaptability and promotional value.

[0012] Preferably, the end of the connecting end block near the connecting sleeve is connected to an insert block, and the insert block has a slot for use on its outside and inside the connecting sleeve.

[0013] Preferably, the connecting sleeve is provided with a reinforcing component on the outside, which is used to apply uniform radial pressure to the connection between the connecting sleeve and the connecting end block, so that the connection forms a tight sealing connection structure to prevent leakage of pressure medium. The reinforcing component includes a clamp sleeved on the outside of the connecting sleeve, the opening end of the clamp is provided with a screw hole, and the screw hole is internally threaded with a fastening bolt.

[0014] Through the above technical solution:

[0015] Before use, the insert at one end of the connecting end block is inserted into the slot opened in the connecting sleeve to connect the flexible pipeline to the connecting assembly. The stepped interference fit eliminates the connection gap, enhances the connection strength, and resists pressure fluctuations and external pulling forces. Then, the clamp is fitted and the fastening bolt is tightened to apply uniform radial pressure to the connecting sleeve, forming a tight sealing structure to prevent coolant leakage. This dual connection method of "stepped interference fit + clamp fastening" not only meets the pipeline reliability requirements under extreme military transportation conditions, but also greatly shortens maintenance time due to its simple operation, thus ensuring the stable operation of military vehicle pipelines.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By incorporating flexible piping and connecting components, this system effectively absorbs stress caused by bending and stretching during use. It also resists low-temperature embrittlement in frigid environments, deformation caused by low air pressure, material aging due to strong ultraviolet radiation, and the impact of thermal expansion and contraction caused by large temperature differences. This completely solves the problem of rupture and leakage in "U"-shaped return water pipes. Compared to traditional pipes, the new system possesses higher flexibility and elastic deformation capacity, maintaining structural integrity under frequent stress. This significantly improves the stability and durability of the piping system, extends its service life, and greatly reduces maintenance frequency, thereby significantly reducing maintenance costs and time-consuming processes. It also significantly alleviates the workload of maintenance personnel. Furthermore, it is particularly useful in extreme conditions such as military transport. In this context, the pipeline not only ensures the stable transmission of engine coolant, preventing abnormal engine wear or mechanical accidents caused by antifreeze leakage, but also significantly improves delivery efficiency, reduces oil consumption, and allows limited wartime maintenance and repair resources to be concentrated on key combat equipment, ensuring the efficient completion of campaign delivery missions. In addition, its excellent performance makes it not only suitable for antifreeze water pipes, but also a replacement for other pipeline processes, achieving multiple uses with one modification. It can be promoted and applied to all units equipped with this type of vehicle. In the field of military transportation, this technology effectively enhances combat support capabilities. In other related industries, it can also effectively improve work efficiency, save energy, and reduce environmental pollution caused by equipment failure, demonstrating strong adaptability.

[0018] 2. By setting up connecting sleeves, connecting end blocks, inserts, slots, and reinforcing components, a dual connection method of "stepped interference fit + clamp fastening" is adopted during connection to achieve the connection between flexible pipelines and connecting components. The stepped interference fit not only effectively eliminates connection gaps but also forms a high-strength physical connection through mechanical interlocking, improving connection strength and ensuring that the pipeline is not easily loosened when subjected to pressure fluctuations and external pulling forces. The clamp fastening operation further enhances the stability of the connection, applying uniform and adjustable radial pressure to the connecting sleeve, resulting in a tight sealing structure at the connection point, effectively preventing coolant leakage. This dual-protection connection method not only meets the stringent requirements for high reliability of the pipeline system under extreme military transportation conditions but also features convenient installation and disassembly, significantly shortening maintenance time. At the same time, it reduces reliance on the professional skills of maintenance personnel, effectively reducing connection failures caused by human error, and providing a solid guarantee for the stable operation of military vehicle pipeline systems.

The first retaining ring 45 and the second retaining ring 46 are located on the outside of the connector ball core 43, and the second retaining ring 46 is located at one end of the compression connector 44.

[0034] The end of the compression connector 44 away from the connector ball core 43 is fixedly connected to the mounting block 6. The mounting block 6 has multiple connection holes equidistantly opened on it. (The mounting block 6 at one end of the universal pressure pipeline is connected to the engine water outlet, and the mounting block 6 at the other end is connected to the water tank return port).

[0035] Through the above technical solution:

[0036] In use, a flexible conduit 1 with straight sections and slight bends replaces the original U-shaped hard bend (the total length of the flexible conduit 1 is longer than the original U-shaped conduit, allowing for stretching allowance).

Compared to traditional conduits, the new conduit... With significantly improved stability and durability, it greatly reduces maintenance frequency, lowers costs and time losses. In addition, under extreme conditions of military transport, it can ensure stable coolant delivery, avoid engine failure, improve delivery timeliness, reduce oil consumption, and save wartime maintenance resources. Due to its excellent performance, it can replace various pipeline processes, achieving "one pipe for multiple uses". It not only effectively enhances combat support capabilities in the military field, but also improves work efficiency, saves energy, and reduces environmental pollution caused by equipment failure in other industries. It has strong adaptability and promotion value.

One end of the connecting end block 2, near the connecting sleeve 3, is connected to an insert block 7. The insert block 7 has a slot 8 for use on its outside and inside the connecting sleeve 3.

[0038] Further, see Figure 3 and Figure 5 As shown, a reinforcing component 5 is provided on the outside of the connecting sleeve 3 to apply uniform radial pressure to the connection between the connecting sleeve 3 and the connecting end block 2, so that the connection forms a tight sealing connection structure to prevent leakage of pressure medium. The reinforcing component 5 includes a clamp 51 sleeved on the outside of the connecting sleeve 3.
