[0011] Reference Figures 1-4 The exhaust device that can meet the requirements of severe collision conditions is characterized by: including a muffler housing 1 and a connecting pipe 2 connected to the middle of the upper surface of the muffler housing 1; an intake pipe 3 is welded to the center of the upper surface of the connecting pipe 2; a hoisting device 4 is connected to the upper edge of the left and right side surfaces of the muffler housing 1; a buffer device 5 is connected to the middle of the left and right side surfaces of the muffler housing 1; a right tailpipe 6 is connected to the lower edge of the right side surface of the muffler housing 1; and a left tailpipe 7 is connected to the lower middle of the left side surface of the muffler housing 1.
[0012] During use, the vehicle's exhaust gas is injected into the muffler housing 1 through the intake pipe 3 and the connecting pipe 2, and finally discharged through the right tailpipe 6 and the left tailpipe 7.
[0013] During a collision, the double-tube lifting device 4 separates the muffler housing 1 from the lifting device 4, while the buffer device 5 buffers the impact force, which can reduce the impact force on the muffler housing 1.
[0014] Furthermore, the muffler housing 1 includes an outer shell 1-1, a top cover 1-2, a groove 1-3, and a through hole 1-4. A top cover 1-2 is welded to the middle of the left and right sides of the outer shell 1-1. A groove 1-3 is provided in the middle of the outer side surface of each top cover 1-2. A through hole 1-4 is provided in the middle of the lower middle of the outer side surface of each top cover 1-2 at the middle of the upper surface of the outer shell 1-1. A connecting pipe 2 is welded inside the upper through hole 1-4. A right tail pipe 6 and a left tail pipe 7 are welded into the through holes 1-4 on the left and right top covers 1-2, respectively.
[0015] The vehicle exhaust gas is injected into the muffler housing 1 through the upper through hole 1-4, and is discharged through the through holes 1-4 on the two top covers 1-2.
[0016] Furthermore, the hoisting device 4 includes a main hook 4-1, a secondary hook 4-2, a lifting column 4-3, and a clamp 4-4. The secondary hook 4-2 is welded to the upper part of the side surface of the main hook 4-1, and the lifting column 4-3 is welded to the center of the outer surface of the main hook 4-1. A clamp 4-4 is inserted into the front edge of the side surface of the main hook 4-1. The main hook 4-1 and the secondary hook 4-2 are welded to the upper part of the outer surface of the top cover 1-2. The outer side of the inner surface of the clamp 4-4 is clamped at the rear edge of the outer shell 1-1.
[0017] During a collision, the impact force is shared by the main hook 4-1 and the auxiliary hook 4-2. The main hook 4-1 and the auxiliary hook 4-2 support each other to dissipate the force and prevent the muffler housing 1 from falling off. At the same time, the hanging column 4-3 is inserted into the car chassis to prevent the main hook 4-1 and the auxiliary hook 4-2 from falling off the car's moving plate. Finally, the clamp 4-4 is installed to protect the connection between the main hook 4-1 and the outer shell 1-1.
[0018] Furthermore, the buffer device 5 includes an outer ring 5-1, an outer mold 5-2, a pad 5-3, and a spring piece 5-4. The outer ring 5-1 is connected to the outer mold 5-2 at the four edges of its outer surface. The pad 5-3 is provided at the middle of the inner side surface of the outer mold 5-2. The spring piece 5-4 is connected to the middle of the inner side surface of the pad 5-3. The outer ring 5-1 is welded to the four edges of the outer surface of the groove 1-3. The inner side surface of the spring piece 5-4 is connected to the inside of the groove 1-3. The outer mold 5-2 is made of 409 metal.
[0019] During the collision, the external pressure squeezes the outer mold 5-2 while the outer mold 5-2 pushes the pad 5-3. When the pad 5-3 moves inward, the spring 5-4 is squeezed and buffered. Meanwhile, the outer mold 5-2 is made of 409 metal, which can recover itself after being impacted. The spring 5-4 and the outer mold 5-2 work together to withstand the impact force and restore the shape of the cross. Finally, the pad 5-3 inserts into the groove 1-3 during the collision.
[0020] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
