Description

Technical Field

[0001] This utility model belongs to the field of nylon tubing technology, and in particular relates to a lightweight and compact automotive nylon tubing. Background Technology

[0002] With the development of the automotive industry, lightweighting and energy conservation and emission reduction have become important trends in the industry. In terms of piping systems, traditional metal pipes have been gradually replaced by nylon pipes due to their disadvantages such as heavy weight, easy corrosion, and poor layout flexibility. Nylon materials have advantages such as light weight, corrosion resistance, chemical resistance, and easy molding, which can adapt to various complex and changing automotive working environments and improve the service life of piping systems.

[0003] Despite continuous advancements in materials, numerous unresolved issues remain regarding the overall design, securing, protection, and layout of automotive nylon tubing systems. These issues directly impact vehicle performance and reliability. Existing technologies suffer from the following problems: 1. Dispersed and inefficient pipe fixing methods: Traditional fixing methods often use a single pipe clamp. For multiple parallel pipes, it is often necessary to set up a separate pipe clamp and fixing point for each pipe. This results in a large number of fasteners, complicated installation procedures, and large space occupation, which runs counter to the design trend of lightweight and compact automobiles. This problem is particularly prominent in areas with limited space.

[0004] 2. Stress concentration risk at pipe bends: Due to the compact layout of the vehicle body, there are many bends in the pipes, which increases the difficulty of forming. At large-angle bends, rigid nylon pipes are prone to stress concentration. Under the long-term action of engine vibration and fluid pressure pulses, it may lead to pipe wall fatigue, microcracks, or even breakage, affecting the reliability of the pipe system.

[0005] 3. Insufficient anti-interference and noise reduction design: When a car is driving on complex road conditions, the body and frame will deform and vibrate, which may cause the pipes to collide and rub against the frame, between pipes, or with other components (such as wiring harnesses and sheet metal parts). This hard contact not only produces unpleasant noise, but also wears down the surface of the pipes over time, reducing their service life and even causing leaks. Existing technology lacks effective and proactive anti-interference measures in a compact space.

[0006] 4. Limited Vibration Control and Auxiliary Fixing Methods: Nylon pipelines are prone to swaying due to vibrations transmitted from the engine over long distances, and existing fixing points lack effective damping and auxiliary fixing methods. Excessive vibration will accelerate the loosening of fixing points and pipeline fatigue.

[0007] 5. Lack of targeted protection for critical parts: In specific risk areas such as where pipes pass through body panel holes or are adjacent to wiring harnesses, sharp edges, or high-temperature components, there is a lack of targeted local reinforcement protection. Ordinary pipes are easily cut, worn, or aged due to high temperatures in these locations, posing safety hazards. Summary of the Invention

[0008] The purpose of this utility model is to provide a lightweight and compact automotive nylon tubing. By setting a double-tube fixing mechanism in the parallel area of ​​the nylon tubing and an integrated tube clamp design, two nylon tubes can be fixed together while avoiding friction between the tubes. This also meets the requirements for quick installation and disassembly of the tubes on the vehicle body and other components. Meanwhile, a single-tube fixing mechanism is set in the single-row area of ​​the nylon tubing to achieve both stable and quick fixing of the tubing, while also achieving lightweight design.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a lightweight and compact automotive nylon tubing, comprising at least two nylon tubings, several double-tube fixing mechanisms, several single-tube fixing mechanisms, and several protective mechanisms; The nylon tube is composed of several shaped tubes and corrugated tubes connected in sequence, and the corrugated tubes are located at the bending points of the nylon tubes. The dual-tube fixing mechanism is an integrated bracket mechanism or an integrated dual-tube clamp mechanism. The dual-tube fixing mechanism is installed between the areas where the two nylon tubes run parallel. The dual-tube fixing mechanism is installed at the forming tube of the nylon tube. The dual-tube fixing mechanism is integrally provided with a frame connection position. Several of the single-tube fixing mechanisms are respectively installed in the area of ​​two nylon tubes in a single row. The single-tube fixing mechanism is installed at the forming tube of the nylon tube. The single-tube fixing mechanism includes a cloth tape wrapped and fixed on the nylon tube and a cedar tie installed on the outside of the cloth tape. The protective mechanism is located in the narrow area between the two nylon tubes. The protective mechanism is a spacer ring fitted onto the molded tube position of the nylon tube. The spacer ring is a shrinkable sleeve structure, and the inner wall of the spacer ring is provided with a number of petal-shaped grooves.

[0010] Furthermore, the integrated bracket mechanism includes an upper plate and a lower plate. An inner clamping tube is integrally provided at one end between the upper plate and the lower plate. Both the upper plate and the lower plate are provided with an outer arc-shaped structure, and an outer clamping tube is formed between the two outer arc-shaped structures. An upper clamping plate and a lower clamping plate that fit together are integrally provided at the other end of the upper plate and the lower plate, respectively. A flange is provided at the edge of the lower clamping plate. The frame connection position is an installation port provided on the upper clamping plate and the lower clamping plate.

[0011] Furthermore, the integrated double-tube clamp mechanism includes two tube clamp parts, and a connecting part is integrally provided between the two tube clamp parts. The frame connection position is a slot structure integrally connected to the connecting part or a cedar head structure integrally provided on the connecting part.

[0012] Furthermore, the nylon tube has several identification stickers on its molded tube portion, and the double tube fixing mechanism is installed at the position of the identification stickers on the molded tube.

[0013] Furthermore, a protective sleeve is provided on the risk area of ​​the nylon tube forming tube. The protective sleeve is a wear-resistant and flame-retardant heat shrink tubing, a spiral wound tube, or a split-type protective sleeve.

[0014] This utility model has the following beneficial effects: 1. This utility model features a dual-tube fixing mechanism in the parallel area of ​​the nylon tubing. The integrated tube clamp design not only secures two nylon tubings together while preventing friction between the tubes, but also meets the requirements for quick installation and disassembly of other components on the vehicle body, thereby improving worker efficiency. Meanwhile, a single-tube fixing mechanism is set in the single-row area of ​​the nylon tubing, which satisfies both stable and quick fixing of the tubing, while achieving lightweighting by reducing unnecessary fasteners and brackets, directly contributing to the overall vehicle lightweighting. Furthermore, the cloth-based adhesive tape of the single-tube fixing mechanism increases the frictional damping of the tube wall, effectively absorbing and dissipating high-frequency vibration energy.

[0015] 2. This utility model uses a formed tube and a corrugated tube to form a pipeline. The corrugated tube, as the bending section of the nylon pipeline, plays a flexible transition role, which not only improves the pipeline layout efficiency, but also the flexible design can better adapt to manufacturing and assembly tolerances. It avoids the problems of high forming difficulty and high assembly difficulty caused by too many bending points in the pipeline. It is suitable for the compact space layout of the vehicle body and can effectively release stress and improve fatigue resistance.

[0016] 3. By designing the protective mechanism, this utility model incorporates petal-shaped spacer rings at points where contact may occur between parallel pipes. Through physical separation, it actively and reliably prevents direct hard contact between the pipes and the frame, as well as between the pipes themselves, effectively reducing noise and pipe wear.

[0017] 4. This utility model strengthens the pre-set risk zone of the pipeline through the design of the protective sleeve, ensuring that the pipeline system can adapt to more complex and harsh vehicle operating environments, and ensuring the stability and service life of the pipeline operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
