[0033] Reference below Figure 1-Figure 3 Description The exhaust assembly 6 according to the embodiment of the utility model can ensure the operating reliability of the sound wave valve 63 and ensure the user experience.

[0034] like Figure 1-Figure 3 As shown, an exhaust assembly 6 according to an embodiment of the utility model includes: an exhaust tail pipe 61 , a sound wave valve 63 and an energy storage component 64 .

[0035] The exhaust tail pipe 61 is used to connect the air outlet of the engine module with the outside world. The sound valve 63 is installed on the exhaust tail pipe 61, and the sound valve 63 is used to adjust the sound of the exhaust flow emitted by the exhaust tail pipe 61. The energy storage component 64 is installed on the exhaust tail pipe 61, and the energy storage component 64 is suitable for absorbing heat when the exhaust tail pipe 61 is exhausting and releasing heat toward the sound valve 63 after the exhaust tail pipe 61 stops exhausting.

[0036] Among them, when the engine 4 is running, exhaust gas is generated inside it. After the exhaust gas is discharged from the engine 4, it can be treated by the exhaust component 6 and then discharged to the outside. The exhaust component 6 can reduce the noise generated by the exhaust gas, thereby avoiding noise pollution when the vehicle is running, and improving environmental protection and comfort.

[0037] Specifically, the exhaust component 6 is provided with an exhaust tail pipe 61, which is configured as a tubular structure, and a single exhaust tail pipe 61 or multiple exhaust tail pipes 61 can be configured according to needs. One end of the exhaust tail pipe 61 is connected to the air outlet of the engine module, and the other end is connected to the outside world. The exhaust gas generated when the engine 4 is running can be discharged to the air inlet end of the exhaust tail pipe 61 through the air outlet of the engine module after treatment, and then transported to the air outlet end of the exhaust tail pipe 61 through the exhaust tail pipe 61, so as to be discharged to the outside world through the exhaust tail pipe 61.

[0038] Furthermore, the exhaust component 6 is provided with a sound valve 63, and the sound valve 63 is arranged in the exhaust tail pipe 61, that is, the gas flowing in the exhaust tail pipe 61 can be discharged to the outside after passing through the sound valve 63. The sound valve 63 can adjust its opening, and then control the flow rate of the gas flowing through the sound valve 63, so as to adjust the sound of the exhaust flow discharged by the exhaust tail pipe 61, meet the different usage requirements of users, and improve the user experience.

[0039] The exhaust assembly 6 is also provided with an energy storage component 64, which is installed in the exhaust tail pipe 61. When the engine 4 is running, heat is generated, so that the exhaust gas discharged by it is also high-temperature gas. When the gas is discharged into the exhaust tail pipe 61, it can flow through the energy storage component 64. The energy storage component 64 can absorb the heat in the gas, and when the engine 4 stops running, the energy storage component 64 can release the absorbed heat, thereby heating the sound wave valve 63. When the ambient temperature is low, the high-temperature gas will produce condensed water and freeze around the sound wave valve 63. The energy storage component 64 heats up the sound wave valve 63 to prevent the sound wave valve 63 from being frozen, thereby ensuring the operating reliability of the sound wave valve 63 and improving the user experience.

[0040] According to the exhaust assembly 6 of the embodiment of the utility model, an energy storage component 64 is provided, and the energy storage component 64 can absorb heat when the exhaust tail pipe 61 is exhausting and release heat toward the sound wave valve 63 after the exhaust tail pipe 61 stops exhausting, thereby eliminating ice around the sound wave valve 63 under low ambient temperature, ensuring the operational reliability of the sound wave valve 63, thereby improving the user experience, achieving better use effect and a wider range of applications.

[0041] In some embodiments, the exhaust assembly 6 further includes a muffler 62 , which is installed on the exhaust tail pipe 61 , and the energy storage element 64 is also used to absorb heat in the muffler 62 .

[0042] Specifically, Figure 1As shown, the exhaust assembly 6 is further provided with a silencer 62, which can be arranged in the exhaust tail pipe 61. The gas generated by the engine 4 when it is running can be discharged into the exhaust tail pipe 61, and then can be transported to the silencer 62 through the exhaust tail pipe 61. The silencer 62 can gradually reduce the pressure of the gas in the exhaust tail pipe 61, and can attenuate the pulsation of the gas pressure in the exhaust tail pipe 61, thereby reducing the noise generated by the gas in the exhaust tail pipe 61, ensuring the user experience. The silencer 62 will generate heat due to exhaust and its own operation when in use, and the energy storage member 64 can absorb the heat. The heat in the muffler 62, that is, when the engine 4 is running, high-temperature gas can be transported to the exhaust tail pipe 61, and the muffler 62 can muffle the high-temperature gas, thereby increasing the temperature of the muffler 62. The heated muffler 62 can radiate heat to the outside of itself, and the energy storage component 64 can absorb the heat of the muffler 62, thereby allowing the energy storage component 64 to absorb heat when the exhaust tail pipe 61 exhausts. When the exhaust tail pipe 61 stops exhausting, the energy storage component 64 can release heat toward the sound valve 63, thereby ensuring the reliability of the operation of the sound valve 63, saving energy, and improving environmental protection.

[0043] In some embodiments, the muffler 62 is located at the air inlet end of the exhaust tail pipe 61 , the sound valve 63 is located at the air outlet end of the exhaust tail pipe 61 , and the energy storage component 64 is located between the muffler 62 and the sound valve 63 .

[0044] Specifically, Figure 1 As shown, a silencer 62 is provided in the exhaust tail pipe 61, and the silencer 62 can silence the gas in the exhaust tail pipe 61 to reduce the noise generated by the exhaust and ensure the user's experience. The silencer 62 is provided at the air inlet end of the exhaust tail pipe 61, that is, when the gas exhausted by the engine 4 enters the exhaust tail pipe 61, it is first silenced by the silencer 62 to ensure the silencer reliability, and the sound valve 63 is located at the air outlet end of the exhaust tail pipe 61, that is, the gas silenced by the silencer 62 can be transported to the sound valve 63 through the exhaust tail pipe 61, and the user can adjust the sound valve 63 to control the sound effect generated by the exhaust gas, and the silenced gas can also be directly discharged from the exhaust tail pipe 61 to meet different needs.

[0045] Furthermore, the energy storage component 64 is arranged between the muffler 62 and the sound valve 63, that is, the gas silenced by the muffler 62 can be transported to the energy storage component 64 through the exhaust tail pipe 61. The gas exhausted by the engine 4 is high-temperature gas. When the muffler 62 silences the gas and when the exhaust tail pipe 61 transports the gas, the temperature of the muffler 62 and the exhaust tail pipe 61 will rise, and the heat radiated outward by the muffler 62 and the exhaust tail pipe 61 can be stored in the energy storage component 64, and when the gas is discharged to the energy storage component 64, the energy storage component 64 can also absorb the heat of the gas, so that the temperature of the gas transported to the sound valve 63 is reduced, thereby avoiding problems such as abnormal operation of the sound valve 63 due to excessive temperature, and extending the service life of the sound valve 63.

[0046] In some embodiments, the distance between the energy storage component 64 and the sound wave valve 63 is smaller than the distance between the energy storage component 64 and the silencer 62 .

[0047] Specifically, the silencer 62 is located at the air inlet end of the exhaust tail pipe 61, the sound valve 63 is located at the air outlet end of the exhaust tail pipe 61, the energy storage member 64 is located between the silencer 62 and the sound valve 63, and the distance between the energy storage member 64 and the sound valve 63 is smaller than the distance between the energy storage member 64 and the silencer 62, that is, the distance between the energy storage member 64 and the silencer 62 is larger, and the distance between the energy storage member 64 and the sound valve 63 is smaller, so that the distance between the energy storage member 64 and the air inlet end of the exhaust tail pipe 61 is larger, and the distance between the silencer 62 and the exhaust tail pipe 61 is smaller. The heat radiated outward from the exhaust tail pipe 61 can be stored in the energy storage component 64, and when the gas is discharged to the energy storage component 64, the energy storage component 64 can also absorb the heat of the gas. When the high-temperature gas is discharged to the sonic valve 63, water vapor will condense around the sonic valve 63. When the exhaust tail pipe 61 stops exhausting, the energy storage component 64 can release heat, thereby avoiding the condensation of water vapor into ice and affecting the operating reliability of the sonic valve 63 when the ambient temperature is low. The distance between the energy storage component 64 and the sonic valve 63 is set to be small, which can ensure the reliability of heat conduction.

[0048] In some embodiments, the energy storage component 64 is fitted with the sound valve 63 ; and / or, the energy storage component 64 is fitted with the silencer 62 ; and / or, the energy storage component 64 is fitted with the exhaust tail pipe 61 .

[0049] Specifically, the silencer 62, the energy storage member 64 and the sound valve 63 are arranged in the exhaust tail pipe 61 and arranged in sequence along the exhaust direction, that is, the energy storage member 64 is arranged between the silencer 62 and the sound valve 63, the energy storage member 64 can absorb heat when the exhaust tail pipe 61 is exhausting, and can release heat to the outside after the exhaust tail pipe 61 stops exhausting, and the energy storage member 64 can be arranged in close contact with the sound valve 63, can also be arranged in close contact with the silencer 62, and can also be arranged in close contact with the exhaust tail pipe 61. When the member 64 is fitted with the muffler member 62 and the exhaust tail pipe 61, the heat radiated outwardly by the exhaust tail pipe 61 and the muffler member 62 is conveniently conducted to the energy storage member 64, thereby ensuring the reliability of energy storage of the energy storage member 64, and the energy storage member 64 is fitted to the sound wave valve 63. When the exhaust tail pipe 61 stops exhausting, the energy storage member 64 can conveniently conduct the stored heat to the sound wave valve 63, thereby ensuring the reliability of heating the sound wave valve 63, so as to ensure the reliability of the operation of the sound wave valve 63.

[0050] In some embodiments, the energy storage component 64 is installed in the exhaust tail pipe 61, and the muffler 62 is installed in or outside the exhaust tail pipe 61; or, the energy storage component 64 is installed outside the exhaust tail pipe 61, and the muffler 62 is installed in or outside the exhaust tail pipe 61.

[0051] Specifically, the energy storage component 64 is installed in the exhaust tail pipe 61, and the muffler 62 is installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61, that is, the energy storage component 64 can be installed in the exhaust tail pipe 61, and the muffler 62 can be installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61, or, the energy storage component 64 is installed outside the exhaust tail pipe 61, and the muffler 62 is installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61, that is, the energy storage component 64 can be installed outside the exhaust tail pipe 61, and the muffler 62 can be installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61, so that the energy storage component 64 can be installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61, and the muffler 62 can be installed in the exhaust tail pipe 61 or outside the exhaust tail pipe 61.

[0052] Furthermore, in actual design, the positions of the silencer 62 and the energy storage component 64 relative to the exhaust tail pipe 61 can be set according to usage requirements, and the energy storage component 64 is set in close contact with the sound valve 63 to ensure the reliability of heat transfer from the energy storage component 64 to the sound valve 63. The silencer 62 and the energy storage component 64 are set apart to ensure the reliability of the silencer 62.

[0053] In some embodiments, the muffler 62 is sleeved outside the exhaust tail pipe 61 ; wherein the energy storage component 64 is sleeved outside the exhaust tail pipe 61 and is separated from the muffler 62 , or the energy storage component 64 is installed on the inner wall of the exhaust tail pipe 61 .

[0054] Specifically, Figure 2-Figure 3 As shown, the silencer 62 is installed on the exhaust tail pipe 61 and is sleeved outside the exhaust tail pipe 61, that is, the silencer 62 is arranged around the exhaust tail pipe 61, and the silencer 62 is arranged close to the air inlet end of the exhaust tail pipe 61, so that after the gas exhausted by the engine 4 enters the exhaust tail pipe 61, it is first silenced by the silencer 62 to ensure the reliability of silencer.

[0055] Furthermore, the energy storage element 64 is also installed on the exhaust tail pipe 61, such as Figure 3 As shown, the energy storage member 64 can be sleeved outside the exhaust tail pipe 61 and spaced apart from the muffler 62. When the high-temperature airflow flows in the exhaust tail pipe 61, the heat can be transferred to the energy storage member 64. When the exhaust tail pipe 61 stops exhausting, the energy storage member 64 can transfer the stored heat to the sound wave valve 63, thereby ensuring the reliability of heating the sound wave valve 63. The energy storage member 64 is sleeved outside the exhaust tail pipe 61 to avoid affecting the circulation of the airflow in the exhaust tail pipe 61, thereby improving the heat absorption efficiency. At the same time, Figure 2 As shown, the energy storage component 64 can also be installed on the inner wall of the exhaust tail pipe 61, thereby saving the installation space of the exhaust tail pipe 61, improving the structural compactness of the exhaust assembly 6, and thus improving the space utilization of the vehicle.

[0056] In some embodiments, an energy storage medium is disposed in the energy storage element 64 , and the energy storage medium is molten salt.

[0057] Specifically, the energy storage component 64 is arranged in the exhaust tail pipe 61, and can absorb heat when the exhaust tail pipe 61 is exhausting and release heat toward the sound wave valve 63 after the exhaust tail pipe 61 stops exhausting. An energy storage medium is arranged in the energy storage component 64, and the energy storage medium can be set to chloride molten salt, etc. The molten salt is composed of alkali metal or alkaline earth metal and halide, silicate, carbonate, nitrate and phosphate. The molten salt has high thermal melting point and high thermal conductivity value as well as high thermal stability and mass transfer rate. Phase change can be used to realize heat storage and release, which can increase the speed of heat storage in the energy storage component 64 and increase the speed of heat transfer from the energy storage component 64 to the sound wave valve 63.

[0058] During the heat storage process, the silencer 62 radiates heat to the molten salt, causing it to change from a solid state to a liquid state, thereby storing the heat in the molten salt. During the heat release process, when the engine 4 is turned off, the molten salt can continuously release heat as a heat storage medium. In the process of changing from liquid to solid, the stored heat energy will be released. The heat storage medium can recover the heat of the exhaust gas of the engine 4, and can achieve heat storage and heat release of the heat storage medium through the phase change of the heat storage medium, that is, the solid state changes to the liquid state, and the liquid state changes to the solid state, thereby achieving the removal of water vapor at the sound wave valve 63.

[0059] Furthermore, the acoustic valve 63 can be set to be made of metal material, that is, when the external temperature decreases, the cooling rate of the acoustic valve 63 is faster than the cooling rate of the molten salt in the energy storage component 64, so that when the external temperature decreases, the temperature of the energy storage component 64 is higher than the temperature of the acoustic valve 63, and then after the exhaust tail pipe 61 stops exhausting, the energy storage component 64 can release heat to the acoustic valve 63, so that the energy storage component 64 can eliminate ice around the acoustic valve 63 when the ambient temperature is low, thereby ensuring the operational reliability of the acoustic valve 63.

[0060] In some embodiments, the exhaust tail pipe 61 includes two exhaust sub-pipes, at least one of which is provided with a sound wave valve 63 and an energy storage component 64 .

[0061] Specifically, Figure 1As shown, the exhaust assembly 6 is provided with an exhaust tail pipe 61, which is configured as a tubular structure, and two exhaust sub-pipes can be provided, one end of the two exhaust sub-pipes are connected to the air outlet of the engine module, and the other end is connected to the outside world. The exhaust gas generated when the engine 4 is running can be discharged to the air inlet end of the two exhaust sub-pipes through the air outlet of the engine module after treatment, and then transported to the air outlet end through the two exhaust sub-pipes to be discharged to the outside world through the two exhaust sub-pipes, and at least one of the exhaust sub-pipes is provided with a sound wave valve 63 and an energy storage component 64, that is, in actual use, a sound wave valve 63 and an energy storage component 64 can be provided in one exhaust sub-pipe according to the use requirements, or a sound wave valve 63 and an energy storage component 64 can be provided in each of the two exhaust sub-pipes to meet different use requirements, and can be applicable to more vehicle models, thereby improving the setting flexibility.

[0062] In some embodiments, the exhaust component 6 also includes a control unit, which is electrically connected to the sound valve 63 and is suitable for controlling the opening of the sound valve 63 to adjust the sound of the exhaust flow emitted by the exhaust tail pipe 61. The exhaust component 6 is also provided with a control unit, which is electrically connected to the sound valve 63, and the control unit can send control instructions to the sound valve 63, thereby making the sound of the exhaust flow emitted by the exhaust tail pipe 61 adjustable. Users can set different sounds according to their preferences, or control the sound valve 63 to open or close, so as to turn on or off the sound effect, meet different usage requirements, and improve user experience.

[0064] The engine assembly 100 according to the embodiment of the utility model includes an engine module and any of the above-mentioned exhaust components 6, the engine module includes an air filter 1, a turbocharger 2, an intercooler radiator 3, an engine 4 and a post-processing module 5, the air filter 1 is connected to the outside air, the post-processing module 5 is connected to the exhaust component 6, and the air filtered by the air filter 1 is suitable for passing through the turbocharger 2, the intercooler radiator 3, the engine 4 in sequence and then flowing to the post-processing module 5.

[0065] Specifically, the engine assembly 100 is provided with an engine module and an exhaust assembly 6, and as Figure 1As shown, the engine module is provided with an air filter 1, a turbocharger 2, an intercooler radiator 3, an engine 4 and a post-processing module 5, etc. The inlet end of the air filter 1 is connected to the external air and the outlet end is connected to the turbine part 21 of the turbocharger 2, so that the air filter 1 can convey airflow to the turbine part 21 of the turbocharger 2. The air filter 1 can filter out dust, sand particles, etc. in the air to ensure the cleanliness of the air entering the turbine part 21. The airflow after supercharging of the turbine part 21 of the turbocharger 2 flows through the intercooler radiator 3 and the engine 4 in sequence, and then flows to the impeller part 22 of the turbocharger 2, and flows to the post-processing module 5 through the impeller part 22 of the turbocharger 2. The post-processing module 5 can process toxic and harmful substances in the exhaust gas of the engine 4 to avoid the exhaust gas of the engine 4 from polluting the environment and improving environmental protection. The treated gas can be conveyed to the exhaust component 6, and discharged to the outside after being subjected to silencing and other treatments by the exhaust component 6, so as to realize the normal operation of the engine assembly 100.

[0066] Among them, the intercooler radiator 3 can reduce the temperature of the high-temperature gas after being pressurized by the turbine part 21 of the turbocharger 2, that is, it can cool the pressurized gas, thereby reducing the heat load of the engine 4, increasing the air intake of the engine 4, and then increasing the power of the engine 4, improving the operating effect of the engine 4.
