[0029] Example:
[0030] A new type of insulation shell for an automobile exhaust system includes a main shell, the surface of the main shell includes a main profile and a main end face, an opening 5 is provided on the main profile, a step surface 7 is provided in the opening 5, the opening 5 is connected to the step surface 7 through a first transition rib assembly, the two sides of the main profile are connected to a first flange surface 11 and a second flange surface 12 respectively through a reinforcing rib assembly, the two sides of the main end face are connected to a third flange surface 14 and a fourth flange surface 15 respectively through a second transition rib assembly, and the first transition rib 6 assembly is also connected to the reinforcing rib assembly.
[0031] It is explained that the opening 5 on the main profile of the main shell is mainly used to install the step surface 7, thereby improving the strength of the overall structure, and can also effectively resist the thermal deformation of metal materials at high temperatures, thereby ensuring the long-term stable operation of the exhaust system. On both sides of the main profile, the introduction of the reinforcing rib assembly not only enhances the deformation resistance of the main shell, but also improves the durability of the entire insulation shell. The first flange surface 11 and the second flange surface 12 are tightly connected to the main shell through the reinforcing rib assembly, forming a stable structural system, which effectively prevents damage caused by vibration or impact. On both sides of the main end surface, the second transition rib assembly tightly connects the third flange surface 14 and the fourth flange surface 15 to the main shell. The cooperation of the second transition rib assembly and the first transition rib 6 assembly also improves the sealing of the entire insulation shell and effectively prevents heat leakage.
[0032] Combined with the accompanying drawings Figure 1-Figure 6As shown, the main profile is a curved surface, and the main profile includes a first profile 1 and a second profile 2. The opening 5 is opened through the first profile 1 and the second profile 2. The step surface 7 is recessed and connected to the inside of the opening 5 through a first transition rib assembly. The recess depth of the step surface 7 is 5 mm. The first transition rib assembly is a first transition rib 6. The first transition rib 6 is arranged along the inner edge of the opening 5 and is connected to the reinforcing rib assembly. The reinforcing rib assembly includes a first reinforcing rib 8 and a second reinforcing rib 13. One side of the first profile 1 is connected to the first flange surface 11 through the first reinforcing rib 8, and the other side of the first profile 1 is connected to the second flange surface 12 through the second reinforcing rib 13.
[0033] It is explained that the main profile is designed as a curved surface, which not only increases the structural strength, but also can disperse the force, so that the insulation shell can better resist deformation when subjected to external impact, and inside the opening 5, the step surface 7 is connected by the first transition rib assembly, which further enhances the strength around the opening 5. The first transition rib assembly adopts the first transition rib 6, which is arranged along the inner edge of the opening 5 and connected to the reinforcing rib assembly. This design ensures the stability of the edge of the opening 5, and also provides a good connection foundation for the reinforcing rib assembly.
[0034] Specifically, the reinforcing rib assembly includes a first reinforcing rib 8 and a second reinforcing rib 13, which are respectively connected to the two sides of the first profile 1 and connected to the first flange surface 11 and the second flange surface 12. The main function of the reinforcing rib is to enhance the structural strength of the product, especially to prevent the product from being deformed or broken when subjected to external pressure or impact. The design of the first reinforcing rib 8 and the second reinforcing rib 13 makes the structure of the entire product more stable and also increases the service life of the product.
[0035] Combined with the accompanying drawings Figure 1-Figure 6 As shown, the main end face includes a first end face 3 and a second end face 4, the second transition rib assembly includes a second transition rib 9 and a third transition rib 10, the first end face 3 is connected to the third flange face 14 through the second transition rib 9, and the second end face 4 is connected to the fourth flange face 15 through the third transition rib 10.
[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
