[0031] The air filter connecting pipeline 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 3 As shown, the air filter connecting pipeline 1 according to the embodiment of the utility model includes a plastic pipe body 100 , a heat insulation cover 200 and a clamp 300 .

[0033] The plastic pipe body 100 is an integral part and is suitable for connecting an air filter and an engine. The heat shield 200 is mounted on the plastic pipe body 100, and the heat shield 200 at least partially covers the outer peripheral surface of the plastic pipe body 100. The clamp 300 surrounds and clamps the plastic pipe body 100, and the clamp 300 extends radially outward from the heat shield 200 of the plastic pipe body 100 and is suitable for being mounted on an engine bracket.

[0034] For example, the plastic pipe body 100 is a thermoplastic elastomer structural part, which is formed by three-dimensional blow molding, and its elasticity and strength are between rubber and plastic. The two ends of the plastic pipe body 100 are respectively connected to the air filter and the engine structure, the heat shield 200 surrounds the plastic pipe body 100 and is located in the middle of the plastic pipe body 100, the clamp 300 is stamped from a steel plate structure, for example, the brand of the clamp 300 is Q235, which surrounds the plastic pipe body 100, the heat shield 200 partially covers the clamp 300, and is separated between the heat source and the plastic pipe body 100, and the clamp 300 extends out of the heat shield 200 and is installed on the engine bracket to keep the plastic pipe body 100 and the engine bracket installed.

[0035] According to the air filter connecting pipeline 1 of the embodiment of the utility model, the plastic pipe body 100 is an integrated structure. The plastic pipe body 100 itself does not need to be assembled. It only needs to connect the plastic pipe body 100 as a whole between the air filter and the engine, which reduces the number and complexity of parts and simplifies the assembly process of the entire air filter connecting pipeline 1. The integrated design of the plastic pipe body 100 brings a more direct and efficient assembly method, reduces the component alignment and adjustment steps during the assembly process, reduces the connection points, reduces the probability of air leakage, simplifies the process flow, reduces the risk of parts falling off, improves assembly efficiency, and helps save time and labor costs. Compared with multi-section pipelines, the integrated plastic pipe body 100 also greatly reduces the flash waste in the production process, saves more costs, and is more beautiful. At the same time, the heat shield 200 is installed on the plastic pipe body 100, at least partially covering the outer peripheral surface of the pipe body 100, which can effectively isolate the heat exchange between the plastic pipe body 100 and the external environment. For example, the heat shield 200 isolates the heat from the engine exhaust pipe, provides additional protection, reduces the impact of thermal stress on the air filter connecting pipe 1, and reduces the risk of aging and embrittlement of the plastic pipe body 100. In addition, the plastic pipe body 100 with an integrated structure has excellent resilience, impact resistance and bending fatigue resistance. Compared with a split pipe body, it is easier to install the heat shield 200 to prevent the heat shield 200 from falling off.

[0036] Therefore, the air filter connecting pipeline 1 according to the embodiment of the utility model has the advantages of reducing the risk of air leakage and parts falling off, improving assembly efficiency, and having good thermal insulation.

[0037] In some specific embodiments of the utility model, the outer peripheral surface of the heat shield 200 is constructed with an aluminum-plated reflective layer. For example, the thickness of the aluminum-plated reflective layer is 0.8 mm, and its heat resistance is far superior to that of galvanized steel plates and cold-rolled steel plates. It hardly changes even after long-term use at temperatures below about 550 degrees, and plays a certain role in heat insulation protection, which helps prevent the high-temperature airflow discharged by the engine from generating heat on surrounding components and connecting pipes, protects the air filter connecting pipe 1 from high temperature, and prolongs its service life. At the same time, the aluminum-plated reflective layer not only has a beautiful surface processing, but also has excellent reflective properties, and can serve as an efficient heat insulation barrier to protect the normal operation of the air filter connecting pipe 1.

[0038] In some specific embodiments of the present invention, Figure 2As shown, the cross section of the heat shield 200 is configured in a semicircular arc shape and the heat shield 200 covers half of the circumference of the plastic pipe body 100. Since the air filter connecting pipe 1 is located above the engine and a part of the pipe passes near the supercharger, the heat shield 200 covers the half of the circumference of the plastic pipe body 100 close to the supercharger, which can reflect part of the heat radiation and prevent the heat from directly irradiating the plastic pipe body 100, which helps to reduce the impact of heat on the air filter connecting pipe 1, reduce the risk of aging of the plastic pipe body 100, and maintain the stability and performance of the air filter connecting pipe 1. Prevent the plastic pipe body 100 from aging and failure due to heat radiation.

[0039] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the heat shield 200 is constructed with a riveted portion 210 that extends beyond its semi-circumferential edge in the circumferential direction, and the riveted portion 210 is riveted to the plastic pipe body 100. The riveted portion 210 can ensure a firm and reliable connection between the heat shield 200 and the plastic pipe body 100 by riveting the heat shield 200 and the plastic pipe body 100, prevent loosening or falling off due to vibration or external force during use, and maintain the stability of the air filter connecting pipe 1. In addition, the rivet connection method can simplify the disassembly and maintenance process of the air filter connecting pipe 1. When the heat shield 200 or the plastic pipe body 100 needs to be replaced or repaired, the operation can be performed more conveniently, saving operation time and improving maintenance efficiency.

[0040] In some specific embodiments of the present invention, Figure 1 As shown, the plastic pipe body 100 includes a straight section 110, a first bent section 120 and a second bent section 130. The straight section 110 is located in the middle of the plastic pipe body 100 and extends in a straight line. The first bent section 120 is connected to one end of the straight section 110 and is bent toward the air filter. The second bent section 130 is connected to the other end of the straight section 110 and is bent toward the engine. A first corrugated portion 111 is constructed between the first bent section 120 and the straight section 110, and a second corrugated portion 112 is constructed between the second bent section 130 and the straight section 110.

[0041] For example, the first corrugated portion 111 and the second corrugated portion 112 are both trapezoidal corrugated portions. Part of the first corrugated portion 111 is located inside the heat shield 200 and connected to the clamp 300, with 8 corrugations. The second corrugated portion 112 is located between the straight section 110 and the second bending section 130, with 11 corrugations. The first corrugated portion 111 and the second corrugated portion 112 and other structures can play a buffering and shock-absorbing role, absorb the vibration and impact generated by the engine during operation, reduce the impact on the plastic pipe body 100 and other components, and extend the service life. In addition, the first corrugated portion 111 and the second corrugated portion 112 help reduce the resistance loss in the pipeline, improve the efficiency of air entering the engine, and are beneficial to improving the performance of the engine.

[0042] In some specific embodiments of the present invention, Figure 1 As shown, the outer peripheral surface of the plastic pipe body 100 is configured with limiting protrusions arranged at intervals along the circumferential direction, and the clamp 300 is configured with positioning holes that cooperate with the limiting protrusions, and the limiting protrusions are suitable for extending into the positioning holes.

[0043] Through the cooperation of the limiting protrusion and the positioning hole, the plastic tube body 100 can be accurately positioned during the fixing process of the clamp 300, ensuring that the position of the plastic tube body 100 relative to the clamp 300 is accurate, and preventing the plastic tube body 100 from shifting or swinging during use. At the same time, the structure of the limiting protrusion and the positioning hole helps to strengthen the structural stability of the connection, making the connection between the plastic tube body 100 and the clamp 300 more secure, improving the bearing capacity and pressure resistance of the connection part, ensuring the safety and reliability of the connection, and thus improving the reliability of the air filter connection pipeline 1.

[0044] In some specific embodiments of the present invention, Figure 3 As shown, the clamp 300 includes a surrounding portion 310 and a mounting portion 320. The surrounding portion 310 surrounds the outer circumference of the plastic tube body 100. The mounting portion 320 is connected to both ends of the surrounding portion 310 and extends radially outward from the plastic tube body 100. The mounting portion 320 is suitable for being penetrated by fasteners and being installed on the engine bracket. The surrounding portion 310 surrounds the outer circumference of the plastic tube body 100, and a portion thereof is tightly fitted with the heat insulation cover 200, which can increase the structural strength of the plastic tube body 100 while supporting the plastic tube body 100. The mounting portion 320 is arranged in parallel on one side of the plastic tube body 100, and is fixed to the engine bracket by penetrating fasteners, so as to firmly fix the air filter connecting pipeline 1, prevent the air filter connecting pipeline 1 from loosening or shifting during operation, and ensure the stable connection of the pipeline.

[0045] In some specific embodiments of the present invention, Figure 1 As shown, the air filter connection pipeline 1 also includes a sealing rubber sleeve 400. The sealing rubber sleeves 400 are respectively sleeved on both ends of the plastic tube body 100. The sealing rubber sleeve 400 at one end of the plastic tube body 100 is connected to the air filter, and the sealing rubber sleeve 400 at the other end of the plastic tube body 100 is connected to the engine. The sealing rubber sleeve 400 is a 2mm thick rubber sleeve, which is installed on the inner wall of the ports at both ends of the plastic tube body 100, ensuring good sealing when the interface of the plastic tube body 100 is connected to the engine interface and the air filter interface, avoiding the situation where the plastic tube body 100 interface is directly connected to the engine interface and the air filter interface and cannot accommodate parts or assembly errors, resulting in sealing failure, ensuring the normal use of the air filter connection pipeline 1, and improving the reliability of the device.

[0046] In some specific embodiments of the present invention, the plastic pipe body 100 is a thermoplastic elastomer. Thermoplastic elastomer materials have good high temperature resistance, can work in an environment of -50℃-125℃ for a long time or in an environment of -70℃-200℃ for a short time, and maintain its stable performance in a high temperature environment, and are not easy to soften, deform or age, thereby ensuring the stability and safety of the plastic pipe body 100. At the same time, the elasticity and strength properties of thermoplastic elastomers are between rubber and plastic, and can bend and deform within a certain range without being easy to break. It has good comprehensive properties such as heat resistance, aging resistance, low temperature resistance and mechanical properties, and can maintain good flexibility even in a low temperature environment, and can adapt to various complex installation environments and connection layouts.
