Abstract
Description
Technical Field
[0001] The utility model belongs to the field of ventilation pipes, and particularly relates to a noise reduction pipe and a vehicle. Background Art
[0002] During the operation of an oil vehicle engine, such as an automobile or motorcycle engine, a large amount of air needs to be inhaled. If the air is not filtered, dust and impurities suspended in the air will be inhaled into the cylinder, which will accelerate the wear of the piston group and the cylinder. To solve the above problems, an air filter is usually installed at the intake end of the engine. The air filter can filter dust and sand grains in the air and protect the engine cylinder, piston, and piston ring from wear by abrasive particles.
[0003] The intake end of the engine is usually connected to the air filter through an intake pipe. When the vehicle is running, since both the air filter and the engine vibrate, the intake pipe between them generally uses a braided pipe for flexible connection to reduce noise. However, in actual use, the noise generated by the engine is often easy to penetrate the braided pipe, resulting in a relatively high overall vehicle noise. Summary of the Invention

[0025] <Example 1>
[0026] This embodiment proposes a vehicle and a noise reduction pipe. The noise reduction pipe is used on the intake pipe between the engine and the air filter of the vehicle. As Figure 1 and Figure 2 shown, the noise reduction pipe includes a first pipe 1, a second pipe 2, a connecting pipe 3, a sound-absorbing cotton 4 and a waterproof film 5. The first pipe 1 is used to connect to the air filter, the second pipe 2 is used to connect to the engine, the connecting pipe 3 is used to connect the first pipe 1 and the second pipe 2, the sound-absorbing cotton 4 is wrapped around the connecting pipe 3, and the waterproof film 5 is wrapped around the sound-absorbing cotton 4. A fixing component is also provided, and the waterproof film 5 is fixed outside the sound-absorbing cotton 4 through the fixing component.
[0027] Specifically, as Figure 2 and Figure 3 shown, a connecting seat 6 is provided at one end of each of the first pipe 1 and the second pipe 2 facing the connecting pipe 3, and the connecting seat 6 is sleeved on the end of the connecting pipe 3. The fixing component includes a fixing ring 71 and a seal 72. The seal 72 is sleeved on the outer periphery of the connecting seat 6, and an annular embedding groove 61 for embedding the seal 72 is provided on the outer periphery of the connecting seat 6; the end of the waterproof film 5 covers the outer periphery of the seal 72, and then the fixing ring 71 is fixed on the waterproof film 5, so that the fixing ring 71 is sleeved on the outside of the connecting seat 6, the seal 72 and the waterproof film 4. The two ends of the waterproof film 5 are pressed between the seal 72 and the fixing ring 71, thereby fixing the waterproof film 5 and the seal 72 to the connecting seat 6 together.
[0028] Two connecting seats 6 are respectively formed at the ends of the first pipe 1 and the second pipe 2. Both ends of the connecting pipe 3 are inserted into the corresponding connecting seats 6 to form inserted parts, and the middle part of the connecting pipe 3 is exposed outside the connecting seats 6 to form an exposed part. The sound-absorbing cotton 4 is wrapped on this exposed part, and both ends of the waterproof film 5 are pressed between the seal 72 and the fixing ring 71, that is, located outside the connecting seats 6, so as to ensure that the waterproof film 5 can wrap the entire sound-absorbing cotton 4 and prevent the sound-absorbing cotton 4 from being corroded by rainwater, affecting the sound-absorbing effect.
[0029] In this embodiment, the connecting pipe 3 is a braided pipe. Both ends of the braided pipe 3 are fixed to the connecting seats 6 by rivets 31. The fixing ring 71 is a cable tie or a metal hoop, and the seal 72 is a sealing sponge.
[0030] In this embodiment, the structures of the first pipe 1 and the second pipe 2 are basically the same, both are 90-degree elbow pipes, and as Figure 1 shown, the bending directions of the first pipe 1 and the second pipe 2 are arranged oppositely. Installation grooves 21 are respectively formed on the circumferential surfaces of the first pipe 1 and the second pipe 2 (as Figure 4 shown, taking the second pipe 2 as an example). An installation frame 8 for installing the noise reduction pipeline is installed on the installation groove 21.
[0031] The initial shapes of the sound-absorbing cotton 4 and the waterproof film 5 can be flat. Then, after the sound-absorbing cotton 4 wraps the connecting pipe 3, the sound-absorbing cotton 4 can form a shape (such as a ring shape) adapted to the exposed part of the connecting pipe 3. Similarly, after the waterproof film 5 wraps the sound-absorbing cotton 4, both ends of it are fixed outside the seal 72, thus forming an adapted shape.
[0032] <Example 2>
[0033] This embodiment is basically the same as the above-mentioned Embodiment 1, except that in this embodiment, the connecting pipe 3 is a rigid pipe, which is fixed between the first pipe 1 and the second pipe 2 by welding or screwing or gluing, and a plurality of sound-absorbing holes are formed on the rigid pipe.
[0034] <Example 3>
[0035] This embodiment is basically the same as the above-mentioned Embodiments 1 and 2, except that in the above-mentioned Embodiments 1 and 2, the two connecting seats 6 are integrally provided with the first pipe 1 and the second pipe 2 respectively, while in this embodiment, the two connecting seats 6 are separately provided with the first pipe 1 and the second pipe 2 respectively.
[0036] Technical effects of the embodiment
[0037] For the noise reduction pipeline of the above embodiments, since the sound-absorbing cotton 4 is arranged outside the connecting pipe, it can eliminate the sound overflowing from the outside of the connecting pipe 3, shield the transmitted sound in all directions, and a waterproof film 5 is sleeved outside the sound-absorbing cotton to prevent the sound-absorbing cotton 4 from being corroded by rainwater and affecting the sound absorption effect.
[0038] Further, the connecting seat 6 is formed by the ends of the first pipe 1 and the second pipe 2. The two ends of the connecting pipe 3 are inserted into the inside of the connecting seat 6. The sound-absorbing cotton 4 is wrapped around the part of the connecting pipe 3 exposed outside the connecting seat 6, and the two ends of the waterproof film 5 are pressed between the seal 72 and the fixing ring 71 (that is, outside the connecting seat 6) to ensure that the waterproof film 5 can wrap the entire sound-absorbing cotton 4 and protect the sound-absorbing cotton 4 in all directions.
[0039] Further, the connecting pipe 3 is a braided pipe, which itself has a good sound-absorbing function. When used in combination with the sound-absorbing cotton, the noise reduction function is further improved.
[0040] Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the new type still belongs to the preferred cases of the present invention and is not used to limit the protection scope of the present invention, as long as it is within the scope of the technical solution of the present invention. For example, in the above embodiments, the noise reduction pipeline is used on the intake pipe between the engine and the air filter. In actual situations, it can also be used in other scenarios that require noise reduction and ventilation.
