Description

Technical Field

[0001] This invention relates to the field of exhaust noise reduction technology, and in particular to an exhaust system and vehicle. Background Technology

[0002] For internal combustion engine exhaust muffler systems, especially vehicle exhaust muffler systems, in addition to meeting national noise regulations, high requirements are placed on the sound quality of the exhaust system to improve the overall marketability of the vehicle. Traditional sound quality adjustment methods mainly adjust the sound quality by changing parameters such as the internal piping, volume, and expansion ratio of the muffler. However, traditional sound quality adjustment methods are limited by the structure of the muffler, affecting the overall vehicle performance, and are difficult, time-consuming, and costly to adjust. Summary of the Invention

[0003] Therefore, it is necessary to provide an exhaust system and vehicle that addresses the problems of traditional sound quality adjustment methods being limited by the structure of the muffler, affecting the overall vehicle performance, and being difficult, time-consuming, and costly to adjust.

[0004] The technical solution is as follows:

[0005] On the one hand, an exhaust system is provided, including:

[0006] An exhaust body, wherein the exhaust body is provided with an exhaust passage;

[0007] A reed is disposed within the exhaust channel, such that the airflow within the exhaust channel can excite the reed to resonate in order to adjust the exhaust sound quality.

[0008] The technical solution will be further explained below:

[0009] In one embodiment, the reed includes a connecting section that is fixedly connected to the inner wall of the exhaust passage.

[0010] In one embodiment, the inner wall of the exhaust channel is provided with a connecting groove, and the connecting section is configured as a connecting piece, which is inserted into the connecting groove.

[0011] In one embodiment, the reed further includes a resonant section, which is spaced apart from the inner wall of the exhaust passage.

[0012] In one embodiment, the resonant section and the connecting section are arranged along the axial direction of the exhaust channel. The connecting section has an arc surface on the side near the resonant section, and the two sides of the arc surface are respectively connected to the outer side wall of the connecting section and the outer side wall of the resonant section.

[0013] In one embodiment, the resonant section is provided with a disturbance flow hole, which is used to disturb the airflow in the exhaust channel.

[0014] In one embodiment, the reed is arranged parallel to the axis of the exhaust passage.

[0015] In one embodiment, the reed plate cooperates with the inner wall of one side of the exhaust channel to form a first exhaust branch, and the reed plate cooperates with the inner wall of the other side of the exhaust channel to form a second exhaust branch. The first exhaust branch and the second exhaust branch are symmetrically arranged along the axis of the exhaust channel.

[0016] In one embodiment, there are at least two reeds, each of which is disposed within the exhaust channel along the axis of the exhaust channel.

[0017] On the other hand, a vehicle is provided that includes the aforementioned exhaust system.

[0018] In the exhaust system and vehicle described in the above embodiments, gas is delivered into the exhaust passage, causing the gas to excite the reed to resonate and generate sound. This effectively adjusts the exhaust sound quality, improving the comfort and marketability of the exhaust system and vehicle. Compared to traditional sound quality adjustment methods, the exhaust system in this application can be designed without changing the basic structure of the exhaust body, ensuring stable exhaust system performance and increasing the design freedom of the exhaust system and vehicle. Furthermore, this application allows adjustment of the resonant frequency of the reed by changing its length, thickness, and shape, thereby obtaining sounds of different frequencies and volumes.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 and Figure 2 As shown, in one embodiment, an exhaust system 10 is provided, including an exhaust body 100 and a reed 200. The exhaust body 100 is provided with an exhaust passage 110; the reed 200 is disposed in the exhaust passage 110, so that the airflow in the exhaust passage 110 can excite the reed 200 to resonate to adjust the exhaust sound quality.

[0028] In the above embodiment, the exhaust system 10 delivers gas into the exhaust channel 110, causing the gas to excite the reed 200 to resonate and generate sound. This effectively adjusts the exhaust sound quality, improving the comfort and marketability of the exhaust system 10. Compared to traditional sound quality adjustment methods, the exhaust system 10 in this application can be designed without changing the basic structure of the exhaust body 100, ensuring stable performance and increasing the design freedom of the exhaust system 10. Furthermore, this application allows adjustment of the resonant frequency of the reed 200 by changing its length, thickness, and shape, thereby obtaining sounds of different frequencies and volumes. This effectively adjusts the exhaust sound quality of the exhaust system 10, and the adjustment is simple, convenient, quick, and low-cost.

[0029] The exhaust body 100 can be an exhaust pipe, a muffler, an internal combustion engine, or other exhaust structure. Specifically, in this embodiment, the reed 200 is fixedly installed at the exhaust end of the exhaust passage 100. This improves the ease of assembly of the exhaust system 10.

[0030] like Figure 1 and Figure 3As shown, the reed 200 further includes a connecting section 210, which is fixedly connected to the inner wall of the exhaust passage 110. In this way, the reed 200 can be integrated with the exhaust body 100, preventing relative movement between the reed 200 and the exhaust body 100 under the action of airflow, ensuring stable exhaust sound quality of the exhaust system 10, and improving the reliability of the exhaust system 10.

[0031] The connecting section 210 is fixedly connected to the inner wall of the exhaust channel 110, which can be done by welding, gluing, snap-fitting, plugging or screwing.

[0032] Optionally, the connecting section 210 is welded integrally with the inner wall of the exhaust passage 110. This prevents the reed 200 from moving relative to the exhaust body 100, ensuring stable exhaust sound quality and improving the reliability of the exhaust system 10. Furthermore, welding reeds 200 of different lengths, thicknesses, or shapes into different exhaust bodies 100 allows for different frequencies and volumes of sound when gas passes through different exhaust bodies 100. When adjusting the exhaust sound quality, simply replacing the exhaust body 100 is sufficient, making the operation simple and convenient.

[0033] Optionally, the inner wall of the exhaust passage 110 is provided with a connecting groove, and the connecting section 210 is set as a connecting piece, which is inserted into the connecting groove. In this way, the reed 200 is detachably connected to the exhaust body 100, so that the exhaust system 10 can obtain different frequencies and volumes of sound by replacing the reeds 200 of different lengths, thicknesses or shapes, thereby improving the applicability of the exhaust system 10.

[0034] Specifically, in this embodiment, connecting grooves are provided on both opposite sides of the inner wall of the exhaust channel 110, and the connecting piece is inserted into the two connecting grooves one by one on both sides of the radial direction of the exhaust channel 110. In this way, the connection area between the connecting piece and the inner wall of the exhaust channel 110 is increased, which increases the connection strength between the spring 200 and the exhaust body 100, thereby improving the reliability and stability of the exhaust system 10.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the reed 200 further includes a resonant section 220, which is spaced apart from the inner wall of the exhaust passage 110. This prevents the resonant section 220 from colliding with the inner wall of the exhaust passage 110 during vibration, thus avoiding noise generation and ensuring stable exhaust sound quality of the exhaust system 10, thereby improving the reliability and stability of the exhaust system 10. Specifically, in this embodiment, the resonant section 220 and the connecting section 210 are integrally formed. This improves the ease of manufacturing the exhaust system 10.

[0036] like Figure 3As shown, optionally, the two outer walls of the resonant section 220 along the radial direction of the exhaust channel 110 are spaced at the same distance from the inner wall of the exhaust channel 110. This ensures that the resonant section 220 will not collide with the inner wall of the exhaust channel 110 during vibration, thus improving the reliability and stability of the exhaust system 10.

[0037] The distance between the two outer walls of the resonant section 220 along the radial direction of the exhaust channel 110 and the inner wall of the exhaust channel 110 can be flexibly adjusted according to the actual needs of use.

[0038] like Figure 1 and Figure 3 As shown, optionally, the resonant section 220 and the connecting section 210 are arranged along the axial direction of the exhaust channel 110. The connecting section 210 has an arc surface 211 on the side near the resonant section 220, and both sides of the arc surface 211 are respectively connected to the outer walls of the connecting section 210 and the resonant section 220. Specifically, in this embodiment, gas is input from the end of the exhaust channel 110 near the connecting section 210 and discharged from the end of the exhaust channel 110 near the resonant section 220. This ensures that the gas around the connecting section 210 can flow smoothly and unimpeded to the area around the resonant section 220, preventing the formation of vortices at the connection between the connecting section 210 and the resonant section 220 that could disturb the gas flow direction within the exhaust channel 110. This ensures that the exhaust sound quality of the exhaust system 10 remains stable, improving the reliability and stability of the exhaust system 10. Specifically, in this embodiment, two arc surfaces 211 are provided, and the two arc surfaces 211 are respectively arranged on both sides of the connecting section 210 along the radial direction of the exhaust channel 110.

[0039] like Figure 1 and Figure 2 As shown, optionally, the resonant section 220 is provided with a disturbance flow hole 221, which is used to disturb the airflow in the exhaust passage 110. In this way, the disturbance flow hole 221 can turbulentize the gas in the exhaust passage 110, so that the exhaust system 10 can obtain more different exhaust sounds and improve the applicability of the exhaust system 10.

[0040] The number and inner diameter of the turbulence channels can be flexibly adjusted according to actual usage needs. For example, the number of turbulence holes 221 can be one, two, or four. Specifically, in this embodiment, one turbulence hole 221 is set, and one turbulence hole 221 is set in the middle region of the resonant section 220.

[0041] like Figure 1 and Figure 3As shown, in one embodiment, the reed 200 is arranged parallel to the axis of the exhaust passage 110. This reduces the force-bearing area of ​​the reed 200, thus reducing the impact force of the gas on the reed 200 and preventing the reed 200 from moving relative to the exhaust body 100 under the influence of the gas, thereby improving the reliability of the exhaust system 10.

[0042] Furthermore, the reed 200 cooperates with the inner wall of one side of the exhaust channel 110 to form a first exhaust branch, and the reed 200 cooperates with the inner wall of the other side of the exhaust channel 110 to form a second exhaust branch. The first and second exhaust branches are symmetrically arranged along the axis of the exhaust channel 110. This ensures that the force on the side of the reed 200 near the first exhaust branch is consistent with the force on the side of the reed 200 near the second exhaust branch, preventing deformation of the reed 200 during use and thus affecting the exhaust sound quality of the exhaust system 10, thereby improving the reliability and stability of the exhaust system 10. Specifically, in this embodiment, the obstruction passage 221 is used to connect the first and second exhaust branches.

[0043] Optionally, there are at least two reeds 200, each reed 200 being disposed within the exhaust passage 110 along its axis. Thus, by changing the number of reeds 200, the exhaust system 10 can produce different exhaust sounds, improving its versatility.

[0044] In one embodiment, a vehicle is provided that includes the exhaust system 10 of any of the above embodiments.

[0045] In the vehicle described above, gas is delivered into the exhaust passage 110 during use, causing the gas to excite the reed 200 to resonate and generate sound. This effectively adjusts the exhaust sound quality, improving vehicle comfort and marketability. Compared to traditional sound quality adjustment methods, the exhaust system 10 in this application can be designed without altering the basic structure of the exhaust body 100, ensuring stable overall vehicle performance and increasing design freedom. Furthermore, this application allows adjustment of the resonant frequency of the reed 200 by changing its length, thickness, and shape, thereby obtaining sounds of different frequencies and volumes. This effectively adjusts the vehicle's exhaust sound quality, and the adjustment is simple, convenient, quick, and cost-effective.
