Technical Field
[0001] This utility model relates to the field of exhaust pipe heat insulation technology, and in particular to a heat insulation structure for automobile exhaust pipes. Background Technology
[0002] With the development of the automotive industry, especially the continuous introduction of high-performance vehicles, the technical requirements for automotive exhaust systems are constantly increasing. Because car engines generate a large amount of heat during operation, exhaust pipe temperatures often rise to several hundred degrees Celsius, especially under high loads or at high speeds. This not only affects the efficiency of the automotive exhaust system but can also impact other surrounding components, such as the engine, transmission system, and fuel lines. Therefore, employing effective heat insulation technology is crucial for improving the operational stability, performance, and lifespan of automotive exhaust systems.
[0003] Traditional exhaust pipe insulation technologies often use a single insulation material, which may result in uneven insulation performance, complex structures, and difficulties in installation, making it difficult to meet the needs of modern high-performance vehicles. Moreover, in some high-temperature environments, a single insulation material may not be able to effectively isolate heat, leading to temperature instability or unsatisfactory insulation performance, thereby affecting the overall performance and safety of the vehicle. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a heat insulation structure for automobile exhaust pipes, aiming to improve the problems of uneven heat insulation effect, complex structure and difficulty in installation in the prior art.

[0006] As a further description of the above technical solution: The first and second protective sleeves are internally fixedly connected to a heat insulation layer, the heat insulation layer is externally fixedly connected to an aluminum foil layer, and the aluminum foil layer is externally fixedly connected to a reinforcing component, which is used to enhance the service life of the protective sleeves.
[0007] As a further description of the above technical solution: The reinforcing component includes a composite material layer, which is fixedly connected to the outside of the aluminum foil layer. A heat insulation pad is fixedly connected to the outside of the composite material layer, and a stainless steel layer is fixedly connected to the outside of the heat insulation pad.
[0008] As a further description of the above technical solution: Both the movable plate and the T-shaped card block are slidably connected inside the groove.
[0009] As a further description of the above technical solution: The T-shaped card block is slidably connected inside the through slot.
[0010] As a further description of the above technical solution: The first protective sleeve and the second protective sleeve are slidably connected to the outer sides of the exhaust pipe body, respectively.

[0018] When assembling the first protective sleeve 2 and the second protective sleeve 5, the first protective sleeve 2 and the second protective sleeve 5 are respectively fitted onto the outside of the exhaust pipe body 1. The movement of the second protective sleeve 5 drives the support plate 6 and the plug-in block 7 to move, inserting the plug-in block 7 into the plug-in groove 13. The spring 9 generates elastic force to drive the moving plate 10 and the T-shaped locking block 11 to move, so that the T-shaped locking block 11 is locked into the through groove 14. At the same time, the movement of the second protective sleeve 5 drives the connecting block 4 to be inserted into the connecting groove 3, which facilitates the rapid assembly of the heat insulation structure.
[0019] Reference Figure 1 , Figure 2 , Figure 5 The first protective sleeve 2 and the second protective sleeve 5 are internally fixedly connected to a heat insulation layer 15. The heat insulation layer 15 is externally fixedly connected to an aluminum foil layer 16. The aluminum foil layer 16 is externally fixedly connected to a reinforcing component, which is used to enhance the service life of the protective sleeve. The reinforcing component includes a composite material layer 17, which is fixedly connected to the outside of the aluminum foil layer 16.

[0020] The heat insulation layer 15 effectively isolates heat and maintains a stable temperature around the exhaust pipe. The aluminum foil layer 16 has good heat reflection capabilities. The composite material layer 17 is used in high-performance vehicles and high-temperature environments. The heat insulation pad 18 provides excellent heat insulation protection. The stainless steel layer 19 prevents high-temperature radiation, thus providing the most suitable heat insulation effect for different temperatures, environments and performance requirements.
[0021] Reference Figure 1 - Figure 5 The movable plate 10 and the T-shaped block 11 are slidably connected inside the groove 8; the T-shaped block 11 is slidably connected inside the through groove 14; the first protective sleeve 2 and the second protective sleeve 5 are slidably connected to the outer sides of the exhaust pipe body 1 respectively; the aluminum foil layer 16, the composite material layer 17, the heat insulation pad 18 and the stainless steel layer 19 are all fixedly connected inside the first protective sleeve 2 and the second protective sleeve 5.

[0023] Working Principle: When using this device, during the assembly of the first protective sleeve 2 and the second protective sleeve 5, the first protective sleeve 2 and the second protective sleeve 5 are respectively fitted onto the outside of the exhaust pipe body 1. The movement of the second protective sleeve 5 drives the support plate 6 to move, and the movement of the support plate 6 drives the insertion block 7 to move, inserting the insertion block 7 into the insertion slot 13. The spring 9 generates elastic force to drive the moving plate 10 to move, causing the moving plate 10 to slide inside the groove 8. The movement of the moving plate 10 drives the T-shaped locking block 11 to move, causing the T-shaped locking block 11 to engage inside the through slot 14. At the same time, the movement of the second protective sleeve 5 drives the connecting block 4 to move, inserting the connecting block 4 into the connecting slot 3. This facilitates the rapid assembly of the heat insulation structure, thereby improving the heat insulation structure's performance. The system is highly practical; the heat insulation layer 15 has excellent high-temperature resistance, effectively isolating heat and maintaining a stable temperature around the exhaust pipe; the aluminum foil layer 16 has good heat reflection capabilities; the composite material layer 17 combines various materials for use in high-performance vehicles and high-temperature environments; the heat insulation pad 18, made of ceramic fiber, glass fiber, mineral fiber, and other materials, effectively wraps the exhaust pipe or engine components, providing excellent heat insulation protection; and the stainless steel layer 19 provides physical protection and prevents high-temperature radiation.
