[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0031] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0032] The following describes an intake system pipeline 1 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0033] like Figure 1-Figure 4 As shown, the intake system pipe 1 is connected to at least the engine, the intercooler and the supercharger to form an intake air circulation flow path. The inner peripheral surface of the intake system pipe 1 is configured with a convexly arranged sound-absorbing texture 100.

[0034] For example, during the operation of the engine, the engine will generate noise, and part of the noise will be transmitted to the intercooler, supercharger and other components through the intake system pipe 1. Since the inner circumferential surface of the intake system pipe 1 is constructed with a sound-absorbing texture 100 with evenly arranged protrusions, the sound-absorbing texture 100 is arranged in an axial and circumferential array along the intake system pipe, which can block the transmission of sound in the horizontal and vertical directions.

[0035] According to the intake system pipe 1 of the embodiment of the utility model, the raised silencer texture 100 can change the propagation path of the sound waves in the intake system pipe 1. The middle of the intake system pipe 1 is a corrugated pipe, and the silencer texture 100 protrudes from the inner wall of the corrugated part. When the sound waves pass through the corrugated part of the pipe inside the intake system pipe 1, the sound waves will be reflected, refracted and diffracted, thereby reducing the propagation of noise and suppressing the reflection of sound waves, thereby achieving the effect of improving the noise reduction.

[0036] In addition, the convex sound-absorbing texture 100 helps to disturb the airflow around the ball, reduce the boundary layer separation between laminar flow and turbulent flow, and further eliminate the airflow noise. And due to the boundary layer separation, the air resistance is reduced, so that the gas passes through the intake system pipeline 1 more efficiently, which helps the intake absorption efficiency. When the airflow passes through the sound-absorbing texture 100, the noise will be hindered by the convexity, resulting in part of the energy being consumed and lost, thereby reducing the propagation of noise.

[0037] Therefore, the air intake system pipeline 1 according to the embodiment of the utility model has the advantages of good noise reduction effect and improved comfort.

[0038] In some specific embodiments of the present invention, Figure 4 As shown, the sound-absorbing texture 100 is configured as convex ridges, which surround and form a plurality of sound-absorbing units 110 that are closed on all sides, and the plurality of sound-absorbing units 110 are arranged in the circumferential direction and the axial direction.

[0039] Multiple sound-absorbing units 110 are evenly arranged in the axial direction and in the axial direction inside the air intake system pipe 1. The surface area of ​​the air intake system pipe 1 in contact with the airflow can be increased through the sound-absorbing texture 100 of the ridge structure, forming multiple closed sound-absorbing units, effectively increasing the effective area of ​​the sound-absorbing material, effectively absorbing the noise generated in the pipe, and improving the noise reduction effect. At the same time, by reducing the generation and propagation of noise, the driving stability of the vehicle system and the driving comfort are improved.

[0040] In some specific embodiments of the present invention, Figure 4As shown, the sound absorbing unit 110 includes a rhombus-shaped sound absorbing unit 111 and / or a hexagonal sound absorbing unit 112. The sound absorbing unit 110 may be composed of a uniform arrangement of the rhombus-shaped sound absorbing units 111 and the hexagonal sound absorbing units 112, or may be composed of a single arrangement of the rhombus-shaped sound absorbing units 111 or the hexagonal sound absorbing units 112.

[0041] The diamond structure and the hexagonal structure can provide more sound-absorbing surface area, increase the absorption and dissipation of noise, and thus effectively reduce the noise level in the pipeline. At the same time, the diamond structure and the hexagonal structure can also more evenly absorb the noise energy in different directions, improve the balance of the sound absorption effect, and eliminate the noise in the intake system pipeline 1 more effectively.

[0042] In some specific embodiments of the present invention, Figure 4 As shown, the sound absorbing unit 110 includes a rhombus-shaped sound absorbing unit 111 and a hexagonal sound absorbing unit 112. The rhombus-shaped sound absorbing unit 111 is arranged along the circumferential direction. The hexagonal sound absorbing unit 112 is arranged along the circumferential direction. The rhombus-shaped sound absorbing unit 111 and the hexagonal sound absorbing unit 112 are alternately arranged along the axial direction.

[0043] For example, the alternating arrangement of the diamond-shaped sound absorbing units 111 and the hexagonal sound absorbing units 112 can effectively absorb and eliminate the sound generated by the airflow passing through the intake system pipe 1, increase the damping effect on the noise, thereby reducing the noise propagation to the interior of the vehicle during engine operation, and improving the driving comfort and efficiency of the vehicle.

[0044] In some specific embodiments of the present invention, the area of ​​each rhombus-shaped sound absorbing unit 111 is not less than 10 mm², and the area of ​​each hexagonal sound absorbing unit 112 is not greater than 50 mm².

[0045] By limiting the area of ​​each rhombus-shaped sound-absorbing unit 111 and hexagonal sound-absorbing unit 112, the sound-absorbing effect can be effectively controlled to ensure that each sound-absorbing unit 110 absorbs noise energy within a suitable range. By specifying the area range, it can be ensured that the sound-absorbing unit has sufficient surface area to absorb noise, while avoiding unnecessary noise reduction losses caused by excessive area. The area of ​​the sound-absorbing unit 110 of appropriate size can make full use of the space in the intake system pipeline 1, ensure the effect of eliminating noise, and make the noise in the pipeline better controlled.

[0046] In some specific embodiments of the utility model, the width of the ridge 11 is 0.5 mm to 3 mm. The ridges 11 of different widths have different noise absorption effects. The appropriate width range can optimize the sound absorption effect and improve the ability to eliminate noise in the pipeline while ensuring the structural strength of the intake system pipeline 1. By limiting the width of the ridge 11, the speed and flow state of the airflow in the pipeline can be controlled, the turbulence and resistance of the airflow can be reduced, the flow performance of the gas can be optimized, and the stability of the vehicle can be improved. In addition, a reasonable width range of the ridge 11 can control the cost of the intake system pipeline 1 structure while ensuring good sound insulation and noise reduction, reduce material consumption, and reduce production costs.

[0047] In some specific embodiments of the present invention, the thickness of the ridge 11 is 0.5 mm to 1 mm.

[0048] The thickness of the rib 11 is specified to optimize the sound absorption effect, so that the rib 11 can more effectively absorb the noise energy in the pipeline and improve the noise control effect. By limiting the thickness range of the rib 11, the stability and strength of the structure of the intake system pipeline 1 can be ensured, and the intake system pipeline 1 is not easily deformed or damaged by external forces during operation while meeting the sound absorption effect.

[0049] In addition, limiting the thickness of the ridge 11 within a certain range can control the manufacturing cost. While ensuring that the sound-absorbing texture 100 has sufficient strength and performance to reduce noise, it can also reduce material consumption and processing costs, reduce the manufacturing cost of the intake system pipeline 1, and improve production efficiency.

[0050] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the intake system pipeline 1 includes a first straight section 101, a second straight section 102 and a corrugated section 103. The first straight section 101 is connected to the engine. The second straight section 102 is connected to the intercooler. The corrugated section 103 is connected between the first straight section 101 and the second straight section 102, and the cross section of the corrugated section forms up and down wave crests and troughs.

[0051] The first straight section 101 and the second straight section 102 are connected to components such as the engine and the intercooler respectively, and the inner sides of the first straight section 101 and the second straight section 102 can be connected to components such as the engine and the intercooler by means of threads or plugging. During the driving process of the vehicle, there may be displacement or vibration between different components. The structure of the corrugated section 103 can cope with deformation in different directions, ensuring that the pipeline remains stably connected during the working process and reducing the problem of rupture or leakage caused by vibration.

[0052] In addition, the presence of the corrugated section 103 can provide a better shock-absorbing and buffering effect. When the engine is running, vibration and pulsating airflow will be generated. The elastic structure of the corrugated section 103 can absorb these vibrations and pulsating forces, reduce the vibration transmitted to the intake system pipeline 1, and help reduce the noise level when the engine is running.

[0053] In some specific embodiments of the present invention, Figure 3 As shown, the trough of the corrugated section 103 corresponds to the position of the diamond-shaped sound absorbing unit 111 , and the peak of the corrugated section 103 corresponds to the position of the hexagonal sound absorbing unit 112 .

[0054] By making the trough of the corrugated section 103 correspond to the diamond-shaped sound absorbing unit 111 and the peak of the corrugated section 103 correspond to the hexagonal sound absorbing unit 112, accurate matching between the sound absorbing unit 100 and the corrugated section 103 can be achieved, so that noise is more easily absorbed when passing through the intake system pipeline 1, thereby improving the overall sound absorption effect and reducing the noise level of the overall vehicle structure.

[0056] The vehicle according to the embodiment of the utility model comprises an engine, a supercharger, an intercooler and an intake system pipeline according to the above embodiment of the utility model.

The sound absorbing unit 110 inside the intake system pipeline 1 refracts and absorbs the airflow to reduce the noise level and improve driving comfort.
