Abstract
Description
Technical Field

[0002] With the development of vehicle technology, automobile exhaust systems play an important role in exhausting engine exhaust, silencing, and reducing emissions. However, the muffler assembly in the automobile exhaust system is large in size and has a low point under the chassis. In extremely cold weather or places with low temperatures, when the engine is idling or driving at low speed, the water vapor produced by engine combustion will be retained in the exhaust pipe. If it is driven in this condition for a long time, it may cause the exhaust system to freeze, resulting in a risk of blockage, blocking the exhaust tail pipe, and then rupturing the exhaust system pipeline. In more serious cases, it may cause damage to the engine cylinder and the engine to be scrapped.
[0003] In the prior art, the exhaust system is mainly made of steel, and the muffler is mainly processed by rolling and wrapping. Some vehicles also use stamping and welding. Due to the special layout structure of the whole vehicle, the exhaust system is arranged at the bottom of the vehicle body and cannot avoid the low point. If the vehicle idles for too long, the water vapor generated during the engine combustion process will pass through the exhaust pipe to form water vapor or water. In an extremely cold environment, the muffler cannot meet the drainage function. If the time is too long, too much frost will accumulate and slowly block the exhaust port. In severe cases, the engine will stall, causing the engine to be scrapped. Utility Model Content

[0029] Reference below Figure 1-Figure 2 A vehicle muffler assembly 100 , a vehicle exhaust system and a vehicle according to an embodiment of the present invention are described.
[0030] Figure 1 1 is a schematic structural diagram of a vehicle muffler assembly 100 according to an embodiment of the utility model. Figure 2 is a schematic structural diagram of a vehicle muffler assembly 100 according to another embodiment of the utility model, Figure 1 and Figure 2 As shown, the vehicle muffler assembly 100 includes: a muffler 110, a first heater 120 and a second heater (not shown in the figure).
[0031] An exhaust tail pipe 130 is disposed on the shell of the muffler 110 , and the first heater 120 is disposed at an exhaust port 140 of the exhaust tail pipe 130 .
[0032] Specifically, when the noise generated by the engine enters the muffler 110 through the exhaust pipe connected to the engine end during the operation of the vehicle engine, the muffler 110 can disperse the energy of the noise through absorption, reflection and interference, adjust the specific noise frequency, and thus reduce the noise level to achieve the best muffler effect. At the same time, the water vapor generated during the combustion of the engine oil in the engine will enter the muffler 110, and form water vapor or water inside the muffler 110. In the embodiment of the present invention, an exhaust tail pipe 130 is provided on the shell of the muffler 110, which is used to discharge the water vapor flowing through the muffler 110 to the external environment through the exhaust tail pipe 130 while reducing the noise level; the first heater 120 is provided at the exhaust port 140 of the exhaust tail pipe 130, which is used to heat the water vapor flowing through the muffler 110 component in extremely cold weather or at low temperatures, so as to avoid the problem of condensation and freezing of water vapor at the exhaust port 140 when the vehicle is idling for a long time, thereby maintaining smooth exhaust.
[0033] Combination Figure 1 and Figure 2 As shown, a drainage hole 150 is provided at the bottom of the shell of the muffler 110 , and the second heater is disposed at the drainage hole 150 .
[0034] Specifically, a drain hole 150 is provided at the bottom of the shell of the muffler to discharge the water accumulated inside the muffler 110. In extremely cold weather, when the temperature inside the muffler 110 decreases, water vapor may condense and form water droplets, and the condensed water droplets will accumulate at the bottom of the muffler 110, so that the water droplets are discharged through the drain hole 150. Furthermore, a second heater is provided at the drain hole 150, which can melt the ice by heating when the water accumulated inside the muffler 110 freezes, and accelerate the evaporation of water around the drain hole 150, so as to further prevent the freezing phenomenon inside the muffler 110 and avoid damage to the muffler 110.
[0035] Thus, the above-mentioned vehicle muffler assembly 100 avoids the problem of freezing of the exhaust system of the vehicle in a cold and low-temperature environment by providing the muffler 110 and respectively providing the first heater 120 and the second heater at the exhaust port 140 and the drain hole 150 of the exhaust tail pipe 130 on the shell of the muffler 110, thereby ensuring that the exhaust system will not freeze and cause the engine to stall or be damaged when the vehicle is idle for a long time in a cold and low-temperature area for preheating or when the user is resting for a long time.

[0041] Specifically, the rotating device can be a bearing, including an outer ring and an inner ring, wherein the outer ring of the bearing is fixedly arranged on the outer shell, that is, the outer shell is in close contact with the outer ring of the bearing. When the outer shell moves, the outer ring of the bearing will also move accordingly, and the inner ring is empty on the outer wall of the drain hole 150 or the exhaust tail pipe 130, and is fixedly connected to the joint part, and can rotate freely on the drain hole 150 or the exhaust tail pipe 130, thereby ensuring uniform heating of the drain hole 150 or the exhaust tail pipe 130 and improving the heating effect.
[0042] In one embodiment of the utility model, the outer shell is threadedly connected to the outer wall of the drain hole 150 or the exhaust tail pipe 130; or, the outer shell is hollowly sleeved on the outer wall of the drain hole 150 or the exhaust tail pipe 130, and a magnet is provided on the outer shell; an electromagnetic induction device for attracting the magnetic force of the magnet is provided on the exhaust tail pipe 130, and the electromagnetic induction device is arranged close to the drain hole 150 or the exhaust tail pipe 130.
[0043] Specifically, the shell and the outer wall of the drain hole 150 or the exhaust tail pipe 130 can be threadedly connected, that is, the inner wall of the shell is provided with threads, and the outer wall of the drain hole 150 or the exhaust tail pipe 130 is also correspondingly provided with matching threads. By rotating the shell, it can cooperate with the threads on the outer wall of the drain hole 150 or the exhaust tail pipe 130, so as to achieve a tight fit between the shell and the drain hole 150 or the exhaust tail pipe 130; or, the shell can be empty on the outer wall of the drain hole 150 or the exhaust tail pipe 130, and a magnet is provided on the shell, and an electromagnetic induction device for attracting the magnetic force of the magnet is provided on the exhaust tail pipe 130, and the electromagnetic induction device is arranged close to the drain hole 150 or the exhaust tail pipe 130. When the electromagnetic induction device is energized, it can generate a magnetic field, which generates magnetic attraction or repulsion with the magnet on the shell, so that the shell can move along the outer wall of the drain hole 150 or the exhaust tail pipe 130.
[0044] In one embodiment of the present invention, the vehicle muffler assembly 100 further includes: a detection device for detecting whether the muffler 110 is blocked.
[0045] Specifically, the vehicle muffler assembly 100 also includes a detection device for real-time monitoring of the state of the muffler 110 to determine whether it is blocked. Specifically, when the muffler 110 is working normally, the detection device can record and monitor relevant performance parameters, such as the flow velocity, pressure difference or sound frequency of the airflow, and judge whether the muffler 110 is blocked by comparing the detected performance parameters with the normal performance parameters, for example, judging whether the current airflow velocity is lower than the normal airflow velocity or whether the current pressure difference is lower than the normal pressure difference.
[0046] In one embodiment of the present invention, the detection device includes a pressure sensor 160 and / or a temperature sensor; wherein the pressure sensor 160 is used to detect the internal pressure of the muffler 110 , and the temperature sensor is used to detect the temperature of the muffler 110 .
[0047] Specifically, the detection device includes a pressure sensor 160 and / or a temperature sensor. The pressure sensor 160 can monitor the internal pressure of the muffler 110 in real time. When the muffler 110 works normally, the internal pressure of the muffler 110 remains stable, and the reading of the pressure sensor 160 is normal, that is, the reading of the pressure sensor 160 is stable within a certain range. When the muffler 110 is blocked, the pressure changes abnormally due to the obstruction of the flow of gas. At this time, it can be judged whether the muffler 110 is blocked by the change of the reading of the pressure sensor 160; similarly, the temperature sensor can monitor the temperature of the muffler 110 in real time. When the muffler 110 works normally, the internal temperature of the muffler 110 remains stable, that is, the reading of the temperature sensor is stable within a certain range. When the muffler 110 is blocked, the flow of gas is blocked and the heat exchange is not smooth, which will cause abnormal temperature. At this time, it can be judged whether the muffler 110 is blocked by the reading of the temperature sensor.
[0048] In one embodiment of the present invention, Figure 1 As shown, the pressure sensor 160 is disposed on a side of the muffler 110 .
[0049] Specifically, the pressure sensor 160 is installed on the side of the muffler 110. On the one hand, since the internal pressure of the muffler 110 is closely related to the airflow flowing through the muffler 110, the position on the side of the muffler 110 can monitor the pressure changes caused by the airflow in different directions on the muffler 110, so that the monitored data of the change in the internal pressure of the muffler 110 is more accurate. On the other hand, setting the pressure sensor 160 on the side can avoid direct airflow impact to extend the service life of the pressure sensor 160. At the same time, setting the pressure sensor 160 on the side can reduce interference with the airflow path, help optimize gas flow, reduce resistance loss, and improve the sound insulation effect.
[0050] In one embodiment of the present invention, Figure 1 As shown, a wiring harness interface is provided on the pressure sensor 160 or the temperature sensor, and the wiring harness interface is connected to the second heater via a first connecting line, and the second heater is connected to the first heater 120 via a second connecting line, and both the first connecting line and the second connecting line are located inside the vehicle muffler assembly 100.
[0051] Specifically, in the vehicle muffler assembly 100, a wiring harness interface is provided on the pressure sensor 160 or the temperature sensor, and a first connecting line can be led out from the wiring harness interface to connect the pressure sensor 160 or the temperature sensor with the second heater. The second heater can be connected to the first heater 120 through the second connecting line, that is, the first heater 120 is connected in series with the second heater, which can supply power to the two heaters for heating. At the same time, the wiring harness interface is connected to the interface of the heater in series, thereby realizing integrated control of the heater. At the same time, the line layout is simplified and the risk of failure is reduced. Furthermore, the first connecting line and the second connecting line are both arranged inside the vehicle muffler assembly 100, which can reduce interference from external factors and protect the line, thereby ensuring efficient and stable operation of the vehicle muffler assembly 100, thereby improving the safety of the vehicle. It can be understood that the first connecting line and the second connecting line include but are not limited to high temperature resistant metal wires 170.
[0052] In one embodiment of the present invention, the vehicle muffler assembly 100 further includes: a prompt device, the prompt device is used to send a prompt signal that the muffler 110 is blocked.
[0053] Specifically, when the muffler 110 is blocked, the electronic control device of the vehicle can receive the blocking signal from the detection device and send the blocking signal to the prompt device, which can send a blocking signal of the muffler 110 according to the blocking signal, prompting the driver to check the working state of the muffler 110. Further, the prompt device can be set to a multiple prompt mode, for example, if the person in the vehicle is asleep or there is no person, the prompt device can give multiple prompts, the prompt time can be gradually increased, and the prompt volume can be gradually increased until the muffler 110 returns to normal working state or the user turns off the prompt function.
[0054] In one embodiment of the present invention, the prompting device includes an image display device and / or a voice prompting device.
[0055] Specifically, the prompt device includes an image display device and / or a voice prompt device, wherein the image display device includes but is not limited to a display screen on the instrument panel or an entertainment system display screen on the central console, which is used to display information about the state of the muffler 110 to the driver, and the voice prompt device includes but is not limited to a vehicle-mounted voice system, which is used to convey the state information of the muffler 110 to the driver through sound. Specifically, the prompt device can be connected to the electronic control device of the vehicle, wherein the image display device can receive data from the electronic control device of the vehicle in real time, and when the muffler 110 is blocked, the image display device can display the working state of the muffler 110 to the driver in an intuitive graphic and text form, for example, displaying the fault location and the cause of the fault, and indirectly displaying a red signal light, etc.; similarly, the voice prompt device can also receive data from the electronic control device of the vehicle in real time, and when the muffler 110 is blocked, the voice prompt device can issue a preset voice warning, such as "the muffler 110 is blocked, please check" and other short and clear prompt information.
[0056] In summary, in a specific embodiment, the electronic control device of the vehicle can receive signals from an ambient temperature sensor and an engine speed sensor provided inside the vehicle, identify the environment in which the vehicle is located and the state of the vehicle engine, and when the ambient temperature is lower than -20°C and the engine speed is lower than 1000rpm or the engine has no wheel speed, it can be determined that the engine is in a parking idle state. At this time, the electronic control device of the vehicle can monitor the pressure sensor 160 signal of the detection device in real time. When the internal pressure of the muffler 110 increases and the detection device determines that the exhaust tail pipe 130 of the muffler 110 is blocked by ice, the electronic control device of the vehicle can start the heating structure, including starting the first heater 120 and the second heater, so as to prevent the muffler tail pipe and the muffler 110 from freezing, and further Furthermore, if the reading of the pressure sensor 160 continues to increase, that is, when the abnormal change in the internal pressure of the muffler 110 continues to be serious, the vehicle's electronic control device can send a blockage signal to the prompt device, prompting the driver to check the vehicle's exhaust system. If the icing is serious, the engine speed can be increased to actively drain the water and increase the exhaust temperature. Furthermore, if the person in the vehicle is asleep or there is no one on the vehicle, the prompt device can repeatedly prompt, for example, 2-3 times, each time at an interval of 2 minutes. If there is still no user operating the vehicle and the abnormal change in the internal pressure of the muffler 110 continues to be serious, the engine can automatically increase the speed by 2000-3000rpm, and automatically start the heater for heating until the internal pressure of the muffler 110 returns to normal.
[0057] In summary, according to the vehicle muffler assembly 100 of the utility model, by providing the muffler 110 and providing the first heater 120 and the second heater at the exhaust port 140 and the drain hole 150 of the exhaust tail pipe 130 on the shell of the muffler 110, the problem of freezing of the exhaust system of the vehicle in a cold and low-temperature environment is avoided, thereby ensuring that when the vehicle is idling for a long time in a cold and low-temperature area for preheating or when the vehicle is idling when the user rests for a long time, the exhaust system will not freeze and cause the engine to stall or be damaged, thereby improving the safety and reliability of the vehicle.
