DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] like Figure 1 As shown, the exhaust pipe between the exhaust system components and the post-processor in the prior art usually passes through the bottom side of the vehicle frame. Since other vehicle components are arranged on the inner side of the vehicle frame, in order to avoid obstacles, the exhaust pipe usually needs to extend to the bottom side of the vehicle frame in a direction approximately perpendicular to the ground, and then extend to the outside of the vehicle frame to connect with the post-processor. The exhaust pipe arranged in this way is relatively long, resulting in a large heat loss in the exhaust gas circulation process.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an embodiment of the utility model provides an exhaust system component, including a supercharger 1, an exhaust butterfly valve 2, a connecting elbow 3 and an exhaust tail pipe 4.

[0036] like Figure 3 and Figure 4 As shown, the first end of the supercharger 1 is connected to the engine exhaust pipe; the first end of the exhaust butterfly valve 2 is connected to the second end of the supercharger 1; the valve body of the exhaust butterfly valve 2 is bent, and the first end and the second end of the exhaust butterfly valve 2 are located on different sides of the vehicle frame 100. The first end of the connecting elbow 3 is connected to the second end of the exhaust butterfly valve 2; the first end of the exhaust tail pipe 4 is connected to the second end of the connecting elbow 3, and the second end of the exhaust tail pipe 4 is used to connect to the post-processor.

[0037] Among them, the exhaust butterfly valve is used to introduce the gas from the engine exhaust pipe into the after-processor.

[0038] The utility model provides an exhaust butterfly valve 2, the first end of the exhaust butterfly valve 2 is located on the inner side of the whole vehicle frame 100, and the valve body is bent, so that the exhaust tail pipe 4 crosses the whole vehicle frame, reducing the flow distance of the engine exhaust gas from the engine exhaust pipe to the post-processor, reducing the heat loss in the process of engine exhaust gas circulation, and increasing the temperature of the engine exhaust gas to the post-processor, thereby improving the nitrogen oxide conversion efficiency, reducing urea crystallization, and reducing the damage and failure of the post-processor. Compared with other methods of increasing the temperature of the engine exhaust gas by changing the engine structure, thereby increasing the temperature of the engine exhaust gas to the post-processor, the utility model has a simpler structure, higher reliability and lower cost.

[0039] Specifically, the second end of the exhaust butterfly valve 2 is rotated outward by 90° to reduce the flow distance of the engine exhaust gas from the engine exhaust pipe to the after-processor.

[0040] The exhaust butterfly valve provided by the utility model effectively solves the problems of the traditional exhaust butterfly valve 2 in terms of space utilization, installation convenience and exhaust efficiency through the innovative bent valve body design and unique installation layout. This design not only improves the overall performance of the vehicle, but also enhances the user experience, and has significant technical advancement and practical application value.

[0041] Through the reasonable design and arrangement of the supercharger 1, the exhaust butterfly valve 2, the connecting elbow 3, and the exhaust tail pipe 4, the flow distance of the engine exhaust from the engine to the post-processor is shortened, the heat loss of the engine exhaust is reduced, and the temperature of the engine exhaust to the post-processor is increased, thereby reducing the heat loss of the engine exhaust when passing through the exhaust tail pipe 4, increasing the temperature of the exhaust to the post-processor, improving the conversion efficiency of nitrogen oxides, reducing urea crystallization, and reducing the damage and failure of the post-processor. By changing the exhaust butterfly valve 2 to shorten the flow distance of the engine exhaust, the structure is simpler, the reliability is higher, and the cost is lower.

[0042] like Figure 4 and Figure 5 As shown, in a feasible embodiment of the utility model, the first end of the exhaust butterfly valve 2 is provided with a first mounting surface 201, and the first mounting surface 201 is matched and connected with the second end of the supercharger 1; this design ensures that the exhaust butterfly valve 2 can be stably and accurately mounted on the supercharger, thereby ensuring the overall performance and stability of the exhaust system. The connection between the first mounting surface 201 and the second end of the supercharger 1 may be bolted, flanged, or connected with other forms of fasteners to ensure the sealing and stability between the two.

[0043] like Figure 5 and Figure 6 As shown, the second end of the exhaust butterfly valve 2 is provided with a second mounting surface 202 and a third mounting surface 203, and the first end of the connecting elbow 3 is provided with a fourth mounting surface 301 and a fifth mounting surface 302; the fourth mounting surface 301 is cooperatively connected with the third mounting surface 203, and the design of these two mounting surfaces enables a tight connection between the exhaust butterfly valve and the connecting elbow, thereby ensuring the smoothness of the exhaust and the sealing of the system.

[0044] In addition to the connection between the third mounting surface 203 and the fourth mounting surface 301, the exhaust butterfly valve 2 is also provided with a second mounting surface 202, which matches the fifth mounting surface 302 of the connecting elbow 3. This double connection design further enhances the connection strength between the exhaust butterfly valve 2 and the connecting elbow 3, and improves the reliability and durability of the entire exhaust system.

[0045] It should be noted that the connection between these mounting surfaces may also be bolted, flanged or connected with other forms of fasteners, and the specific choice depends on the design requirements and actual working conditions. Through reasonable mounting surface design, the connection between the exhaust butterfly valve 2, the supercharger 1 and the connecting elbow 3 is made more compact, reducing space occupation, which is beneficial to the layout design of the vehicle or equipment.

[0046] like Figure 4 and Figure 5 As shown, in a feasible embodiment of the present invention, the second end of the supercharger 1 is provided with a first through hole 101, and the first end of the exhaust butterfly valve 2 is provided with a second through hole 204, and the second through hole 204 cooperates with the first through hole 101, and cooperates with the first fastener to fix the supercharger 1 to the engine exhaust pipe. The first fastener generally refers to fasteners such as bolts, nuts, and pins, which pass through the first through hole 101 and the second through hole 204 to firmly connect the supercharger 1 and the exhaust butterfly valve 2 together. The selection and installation of fasteners must ensure sufficient fastening force and sealing to prevent exhaust leakage.

[0047] like Figure 2As shown, in a feasible embodiment of the present invention, the first end of the exhaust butterfly valve 2 is provided with a threaded hole 205, which cooperates with the second fastener to fix the exhaust butterfly valve 2. This connection mode ensures that the exhaust butterfly valve 2 can be firmly installed in the required position.

[0048] In a feasible embodiment of the utility model, the second end of the exhaust butterfly valve 2 is provided with a first mounting shaft 206, and the first end of the connecting elbow 3 is provided with a first mounting hole 303, and the first mounting hole 303 is fixed with the first mounting shaft 206. This design enables the connecting elbow 3 to be accurately connected to the exhaust butterfly valve 2, and further connected by fasteners to ensure the stability and sealing of the entire system. On the basis of the shaft hole matching, fasteners are usually used to firmly connect the exhaust butterfly valve 2 and the connecting elbow 3. These fasteners generate friction through pre-tightening force, thereby preventing the connecting parts from loosening or falling off during operation.

[0049] like Figure 4 and Figure 5 As shown, in a feasible embodiment of the utility model, the second end of the connecting elbow 3 is provided with a second mounting shaft 304, the first end of the exhaust tail pipe 4 is provided with a second mounting hole 401, and the second mounting shaft 304 and the second mounting hole 401 are matched and connected. The second mounting shaft 304 is inserted into the second mounting hole 401 to form a tight shaft-hole fit. This matching method can ensure the centering of the two components at the connection point and prevent air leakage or vibration caused by misalignment. In order to further enhance the stability of the connection, fasteners (such as bolts, nuts, etc.) are usually used to fix the second mounting shaft 304 in the second mounting hole 401. The fasteners apply a pre-tightening force to tightly combine the two components to prevent loosening due to vibration or external force.

[0050] like Figure 4 As shown, the second end of the exhaust tail pipe 4 is provided with an eighth mounting surface 402 for connecting and fixing the after-processor, thereby ensuring a stable connection between the exhaust tail pipe 4 and the after-processor.

[0051] like Figure 3 and Figure 4As shown, in a feasible embodiment of the utility model, a fixing bracket 5 is also included, which is sleeved on the outer periphery of the exhaust tail pipe 4, and the fixing bracket 5 is used to fix the exhaust tail pipe 4 to the whole vehicle beam 100. The exhaust tail pipe 4 is provided with a third mounting shaft 403 for cooperating with the fixing bracket 5. The fixing bracket 5 provides a stable support for the exhaust tail pipe 4, ensuring that the exhaust tail pipe 4 will not be displaced or loosened due to vibration or external force during the driving of the vehicle. The fixing bracket 5 can also play a role in shock absorption and buffering, reducing the vibration of the exhaust tail pipe 4 caused by the operation of the engine or other vibration sources. This helps to protect the exhaust tail pipe 4 and its connecting parts from damage, and reduce the interference of noise and vibration to passengers. By fixing the exhaust tail pipe 4 to the whole vehicle beam 100, the fixing bracket 5 ensures the overall safety of the exhaust system. Even under complex or harsh driving conditions, the exhaust tail pipe 4 can maintain its stable position and will not fall off or be damaged due to unexpected circumstances.

[0052] like Figure 4 As shown, specifically, the fixing bracket 5 is provided with a ninth mounting surface 501 for cooperating with the third mounting axis 403, a tenth mounting surface 502 for cooperating with the vehicle frame 100, and a fourth through hole 503 for receiving bolts to fix the fixing bracket 5 and the exhaust tail pipe 4 to the vehicle frame 100.

[0053] like Figure 2 and Figure 6 As shown, in a feasible embodiment of the utility model, the second end of the exhaust butterfly valve 2 is provided with a positioning groove 207, and the first end of the connecting elbow 3 is provided with a positioning boss 305, and the positioning groove 207 is matched and connected with the positioning boss 305. The design of the positioning groove 207 and the positioning boss 305 makes it easier to achieve accurate alignment between the exhaust butterfly valve 2 and the connecting elbow 3 when connected. This design reduces the error in the installation process and ensures the correct matching between the connecting parts. In addition to the stability provided by the shaft hole matching, the matching of the positioning groove 207 and the positioning boss 305 further enhances the stability of the connection. They are interlocked to form a more compact and stable connection structure, which helps to resist vibration and external force. During long-term use, due to factors such as vibration and temperature changes, the connecting parts may become slightly loose. The matching connection of the positioning groove 207 and the positioning boss 305 can prevent the occurrence of such looseness to a certain extent and maintain the stability and reliability of the connection.

[0054] like Figure 4 and Figure 5As shown, in addition, the first end of the supercharger 1 is provided with a sixth mounting surface 102 that matches the engine exhaust pipe, and a third through hole 103 for receiving a bolt to fix the supercharger 1 to the engine exhaust pipe. The first end of the supercharger 1 and the engine exhaust pipe are sealed by a gasket, and the bolt is fixed to the engine exhaust pipe through the third through hole 103 of the supercharger 1. The second end of the supercharger 1 is provided with a seventh mounting surface 104 that matches the first mounting surface 201, so as to achieve a stable connection between the supercharger 1 and the exhaust butterfly valve 2.

[0055] In summary, the exhaust system components provided by the utility model include a supercharger 1, an exhaust butterfly valve 2, a connecting elbow 3, an exhaust tail pipe 4 and a fixing bracket 5. Compared with the traditional exhaust butterfly valve structure layout, the exhaust butterfly valve of the utility model rotates outward 90°, so that the exhaust tail pipe 4 crosses the vehicle frame 100, reducing the flow distance of the engine exhaust from the engine to the post-processing module, thereby reducing the heat loss of the engine exhaust when passing through the exhaust pipeline, increasing the temperature of the exhaust to the post-processor, improving the conversion efficiency of nitrogen oxides, reducing urea crystallization, and reducing the damage and failure of the post-processor. By changing the layout of the exhaust butterfly valve to shorten the flow distance of the engine exhaust, the structure is simpler, the reliability is higher, and the cost is lower.

[0056] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6, wherein the sixth mounting surface 102 of the supercharger 1 cooperates with the exhaust pipe of the engine, and is sealed by a gasket, and the bolts fix the supercharger 1 to the exhaust pipe of the engine through the third through hole 103; the first mounting surface 201 of the exhaust butterfly valve 2 cooperates with the seventh mounting surface 104 in the supercharger 1, and is sealed by a gasket, and the bolts pass through the second through hole 204 and the first through hole 101 of the supercharger 1 in sequence to fix the exhaust butterfly valve 2 to the supercharger 1, and the bolts connect the exhaust butterfly valve 2 to the bracket through the second through hole 204 of the exhaust butterfly valve 2, thereby increasing the stability of the exhaust butterfly valve 2 and reducing the failure and motion interference of the exhaust butterfly valve 2 caused by vibration during the operation of the vehicle; the first mounting shaft 206 of the exhaust butterfly valve 2 extends into the first mounting hole 303 of the connecting elbow 3, and the fifth mounting surface 302 of the connecting elbow 3 is connected to the second mounting hole 303 of the exhaust butterfly valve 2. The fourth mounting surface 202 cooperates with the fourth mounting surface 301 of the connecting elbow 3 and the third mounting surface 203 of the exhaust butterfly valve 2, and the connecting elbow 3 is fixed to the exhaust butterfly valve 2 by a clamp; the second mounting axis 304 of the connecting elbow 3 extends into the second mounting hole 401 of the exhaust tail pipe 4, and is sealed by a gasket, and the exhaust tail pipe 4 is fixed to the connecting elbow 3 by a clamp, and the eighth mounting surface 402 of the exhaust tail pipe 4 cooperates with the after-processor, and is sealed by a gasket, and the exhaust tail pipe 4 is fixed to the after-processor by a clamp; the fourth through hole 503 of the fixing bracket 5 cooperates with the third mounting axis 403 of the exhaust tail pipe 4, and the ninth mounting surface 501 of the fixing bracket 5 cooperates with the vehicle frame 100, and the bolts pass through the fourth through hole 503 of the fixing bracket 5 to fix the fixing bracket 5 and the exhaust tail pipe 4 to the vehicle frame, thereby increasing the stability of the exhaust tail pipe 4.
