Description

Technical Field

[0001] This utility model belongs to the field of exhaust pipe technology, and in particular relates to an automobile exhaust pipe. Background Technology

[0002] The exhaust pipe is a structural component in the engine exhaust system used to expel exhaust gases produced by the engine, reduce noise, and filter exhaust gases to reduce pollution. It is usually located under the vehicle chassis. The presence of the exhaust pipe is of great significance in ensuring the continuous and stable operation of the vehicle and reducing the noise generated during engine operation, thus minimizing interference with the surrounding environment and people.

[0003] As disclosed in the utility model patent application CN219262497U, this utility model relates to the field of exhaust pipe technology. The exhaust pipe includes a pipe body, with several connecting rings fixedly disposed on one outer surface of the pipe body, each connecting ring being adapted to an external fastener. A connecting mechanism is fixedly connected to the exhaust end of the pipe body, and a fixing block is fixedly connected to one outer surface of the connecting mechanism. A base plate is fixedly connected to one outer surface of the fixing block, and several clamping blocks are fixedly connected to one outer surface of the base plate. Two clamping springs are fixedly connected to one inner surface of each clamping block, and a fixing ring is fixedly disposed at one end of each clamping spring. An extension pipe is fixedly disposed at the exhaust end of the pipe body, and the extension pipe is adapted to the fixing rings. This solves the problem of inconvenient replacement of existing automotive exhaust pipes. However, in the application of this technical solution, the exhaust pipe located at the bottom of the car is relatively close to the ground, and there are usually no protective measures such as chassis armor. When the vehicle is driving on complex road surfaces, it is easy to bump into the exhaust pipe and cause damage, affecting the normal operation of the exhaust system. There is a technical problem that the exhaust pipe cannot be buffered and protected against collisions to ensure its normal exhaust operation. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-4As shown, this utility model is an automotive exhaust pipe, including an exhaust pipe body 1, and further including: a muffler 2 disposed on one side of the exhaust pipe body 1, a connecting pipe 5 disposed on one side of the muffler 2, the connecting pipe 5 communicating with the muffler 2, the muffler 2 communicating with the exhaust pipe body 1, annular mounting clamps 3 disposed on both sides of the outside of the muffler 2, the mounting clamps 3 being symmetrically arranged on the outside of the muffler 2, a protective cylinder 4 disposed on the outside of the muffler 2, and a fixing sleeve 9 disposed on the outside of the muffler 2, the fixing sleeve 9 being disposed in three sets, the fixing sleeve 9 being evenly spaced on the outside of the muffler 2, and a spring 10 disposed on the outside of the fixing sleeve 9, the spring 10 being evenly spaced on the outside of the fixing sleeve 9. The springs 10 are arranged at intervals, and the outer end of the springs 10 is fixedly connected to the inner side of the protective cylinder 4. This allows the protective cylinder 4 to be connected and installed outside the muffler 2. The protective cylinder 4 isolates and protects the muffler 2, preventing the exhaust pipe from overheating and affecting the normal operation and service life of surrounding components, and even potentially affecting the driving experience and safety. Furthermore, when foreign objects on the road collide with the muffler 2 during vehicle operation, the springs 10 buffer and reduce the impact force generated by the collision, thereby protecting the muffler 2 and ensuring the safety of the exhaust pipe. The protective cylinder 4 has through holes 6 inside, which are arranged at equal intervals inside the protective cylinder 4. The through holes 6 can also meet the safe heat dissipation requirements of the exhaust pipe.

[0024] In use, the protective cylinder 4 is connected to the outside of the muffler 2 by the spring 10 set outside the fixed sleeve 9. The protective cylinder 4 isolates and protects the muffler 2 to prevent the exhaust pipe from overheating and affecting the normal operation and service life of the surrounding components. At the same time, the through hole 6 set inside the protective cylinder 4 can meet the exhaust pipe's safe heat dissipation requirements. Furthermore, when foreign objects on the road collide with the muffler 2 during vehicle operation, the spring 10 buffers and reduces the impact force generated by the collision to protect the muffler 2 and thus ensure the safety of the exhaust pipe.

[0025] As a further implementation of this embodiment, such as Figure 1 and Figure 4As shown, a barrier and protection assembly is provided on the other side of the exhaust pipe body 1. The protection assembly includes a protective pipe 8, which is located on the other side of the exhaust pipe body 1. A stabilizing sleeve 14 is provided on the other side of the inner sidewall of the protective pipe 8. The stabilizing sleeve 14 is inserted into the interior of the exhaust pipe body 1. A connecting ear 7 is provided on the outer side of the exhaust pipe body 1 and the outer side of the protective pipe 8. A mounting bolt 13 passes through the interior of the connecting ear 7. The stabilizing sleeve 14 is inserted into the interior of the exhaust pipe body 1, and the connecting ear 7 is fixedly connected by the mounting bolt 13, thereby achieving the purpose of firmly installing the protective pipe 8 on the exhaust side of the exhaust pipe body 1. The protective pipe 8 has protective baffles 12 installed at the top and bottom of its inner side. The protective baffles 12 are installed at an angle and staggered inside the protective pipe 8. The protective baffles 12 are used to prevent mud and water from being thrown into the exhaust pipe when the vehicle is driving in rainy or snowy weather, which would cause blockage and lead to problems such as weak acceleration, reduced power, and excessive exhaust emissions. The protective pipe 8, which is installed at an angle, can ensure that the exhaust gas is discharged smoothly. A drain hole 11 is installed on one side of the inner sidewall of the protective pipe 8. The drain holes 11 are arranged at equal intervals on one side of the inner sidewall of the protective pipe 8. The water produced when the engine is working and the ethanol gasoline is burning, as well as the rainwater falling on the exhaust pipe, can be discharged normally through the drain holes 11.

[0026] When in use, the stabilizing sleeve 14 is inserted into the interior of the exhaust pipe body 1, and the connecting ear 7 is fixedly connected by the mounting bolt 13, thereby firmly installing the protective pipe 8 on the exhaust side of the exhaust pipe body 1. The protective baffle 12, which is inclined and staggered on the inner side of the protective pipe 8, prevents mud and water from being thrown into the exhaust pipe when the vehicle is driving in rainy or snowy weather, causing blockage and resulting in problems such as weak acceleration, reduced power, and excessive exhaust emissions. The protective pipe 8, which is inclined outward, can ensure that the exhaust gas is discharged smoothly, and the water produced when the engine is working and the ethanol gasoline is burning, as well as the rainwater falling on the exhaust pipe, can be discharged normally through the drain hole 11.

[0027] Working principle: During use, the protective pipe 8 is installed under the car chassis via the mounting clamp 3. The stabilizing sleeve 14 is inserted into the interior of the exhaust pipe body 1, and the connecting ear 7 is fixedly connected by the mounting bolt 13, thus securely installing the protective pipe 8 on the exhaust side of the exhaust pipe body 1. During vehicle operation, exhaust gas is emitted through the exhaust pipe body 1 and noise is reduced by the muffler 2. At the same time, the protective sleeve 4 isolates and protects the muffler 2, preventing the exhaust pipe from overheating and affecting the normal operation and service life of surrounding components. The through hole 6 also meets the safe heat dissipation requirements of the exhaust pipe. Furthermore, during vehicle operation, the road... When a foreign object collides with the muffler 2, the spring 10 buffers and reduces the impact force to protect the muffler 2 and ensure the safety of the exhaust pipe. In rainy or snowy weather, the protective baffle 12 can prevent mud and water from being thrown into the exhaust pipe and causing blockage, which may lead to problems such as weak acceleration, reduced power, and excessive exhaust emissions. The outwardly inclined protective pipe 8 can ensure that the exhaust gas is discharged smoothly. In addition, the drain hole 11 can allow the water produced when the engine is working and the ethanol gasoline is burning, as well as the rainwater falling on the exhaust pipe, to drain normally, thereby ensuring the safe and stable operation of the car's exhaust pipe for exhaust work.
