[0030] Embodiment one

[0031] As Figures 1 to 3As shown, this embodiment provides an intake manifold assembly with noise reduction function, including a pipe 1 and an external pipe 10. Here, the pipe 1 is the intake manifold, and the external pipe 10 is the engine connection port. The inner wall of the pipe 1 is fixedly connected with sound insulation cotton 2. The sound insulation cotton 2 is made of reinforced and toughened nylon. Reinforced and toughened nylon is an engineering plastic in which glass fiber is added to nylon raw material to enhance its mechanical properties. It has excellent strength, rigidity and heat resistance, as well as good corrosion resistance and low coefficient of friction. It also has good sound insulation effect, thereby effectively reducing noise. Both ends of the pipe 1 are fixedly connected with mounting plates 3. The two ends of the sound insulation cotton 2 are respectively fixedly connected to the adjacent side of the two mounting plates 3. The other end of the mounting plate 3 is fixedly connected with a connecting pipe 4. Here, the mounting plate 3 provides stable support for the connecting pipe 4.

[0032] Example 2

[0033] like Figures 1 to 3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that: one end of the connecting pipe 4 contacts one end of the outer pipe 10; an inner pipe 5 is fixedly connected to the inner wall of the connecting pipe 4, providing stable support for the inner pipe 5; the outer side of the inner pipe 5 is slidably connected to the inner wall of the outer pipe 10; an elastic sealing assembly is fixedly connected to the inner wall of the inner pipe 5, including an inner box 6; the outer side of the inner box 6 is fixedly connected to the inner wall of the inner pipe 5, providing support for the inner box 6; a rubber pad 7 is slidably connected to the inner wall of the inner box 6, providing stable sliding space for the rubber pad 7; a limiting plate 8 is fixedly connected to one side of the rubber pad 7. The outer sliding connection is to the inner wall of the inner box 6. The limiting plate 8 here can effectively prevent the rubber pad 7 from accidentally detaching from the sliding inner wall of the inner box 6. The inner box 6 is equipped with multiple springs 9. One end of the spring 9 is fixedly connected to one side of the inner wall of the inner box 6, and the other end of the spring 9 is fixedly connected to one side of the limiting plate 8. The spring 9 here is in a compressed state and can generate a reaction force, so that the rubber pad 7 has an outward protrusion force. The inner wall of the outer pipe 10 is fixedly connected to a stop 11. One side of the inner box 6 is in contact with one side of the stop 11. Because the stop 11 squeezes the rubber pad 7, it retracts into the inner wall of the inner box 6, thereby ensuring the sealing when the intake manifold is connected to the engine.

[0034] One side of the rubber pad 7 is in contact with one side of the block 11, the outer connecting pipe 10 is rotatably connected with the rotating ring 12, the inner wall of the rotating ring 12 is slidably connected with the outer part of the connecting pipe 4, the inner wall of the rotating ring 12 is fixedly connected with two clamping blocks 13, the clamping blocks 13 are in clamping relationship with the connecting pipe 4, when the connecting pipe 4 and the outer connecting pipe 10 need to be connected, the connecting pipe 4 and the outer connecting pipe 10 can be placed horizontally first, so that they are in the same horizontal line, then the rotating ring 12 is rotated, so that the clamping blocks 13 are clamped into the grooves in the outer part of the connecting pipe 4, which is more convenient for installation and disassembly, thereby reducing downtime, and because the block 11 presses the rubber pad 7, the rubber pad 7 is shrunk into the inner box 6, thereby pressing the spring 9 to generate a reaction force, so that the contact between the two is more closely, and the sealing performance is improved.

[0035] Working steps

[0036] Firstly, in the air intake process, the airflow enters the engine through the pipeline 1. The soundproof cotton 2 fixedly connected to the inner wall of the pipeline 1 is made of reinforced and toughened nylon material. This material has good sound insulation effect and can effectively absorb and block the noise generated by the airflow, thereby reducing the influence of the intake noise on the surrounding environment. At the same time, the presence of the soundproof cotton 2 also helps to stabilize the airflow, making the airflow more smoothly enter the engine.

[0037] Secondly, when the intake manifold needs to be connected with the engine, the connecting pipe 4 and the outer connecting pipe 10 are placed horizontally first, so that they are in the same horizontal line. Then the rotating ring 12 is rotated, so that the clamping blocks 13 are clamped into the grooves in the outer part of the connecting pipe 4, realizing the quick connection of the connecting pipe 4 and the outer connecting pipe 10 (the disassembly can be completed by reversing the operation). This installation method is not only fast and convenient, but also can ensure the firmness of the connection.

[0038] After the connection is completed, the block 11 in the outer connecting pipe 10 will press the rubber pad 7, so that it is shrunk into the inner box 6. This action will cause the spring 9 in the inner box 6 to be compressed, generating a reaction force. This reaction force makes the rubber pad 7 have an outward protruding force, thereby further pressing the spring 9, so that the contact between the rubber pad 7 and the block 11 is more closely. This close contact can effectively prevent gas leakage and ensure the sealing performance between the intake manifold and the engine, thereby improving the working efficiency of the engine.

[0039] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
