Description

Decorative tailpipe assembly

technical field

The utility model relates to an automobile exhaust tailpipe, in particular to a decorative tailpipe assembly.

Background technique

At present, the relatively common decorative tailpipe assembly is generally composed of a single circular pipe whose diameter remains basically constant. When discharging exhaust gas, because the diameter of the circular pipe remains unchanged, the exhaust gas discharge is not very smooth and the discharge speed is slow. Exhaust gas residence time is longer.

Utility model content

The technical problem to be solved by the utility model is to provide a decorative tail pipe assembly with smooth exhaust gas discharge.

In order to solve the above technical problems, the technical solution provided by the utility model is as follows: it includes an air intake pipe with a circular cross section, and an air outlet pipe with a flat oval cross section, the diameter of the air outlet pipe is larger than that of the circular air intake pipe, and the A connecting ring with a U-shaped section is provided between the air outlet pipe and the air inlet pipe. The outer wall of the air outlet end of the air inlet pipe is connected to the bottom wall of the connection ring, and the inner wall of the air inlet end of the air outlet pipe is connected to the top of the connection ring. wall connection.

The air outlet end of the air outlet pipe is formed with an inwardly rolled crimp with a circular cross-section, and the crimp and the air outlet pipe are integrally structured.

The bottom wall of the air outlet pipe is also provided with a water leakage hole, which is a rectangular hole and extends along the length direction of the air outlet pipe body.

The decorative tailpipe assembly of the utility model is provided with an outlet pipe whose diameter is larger than that of the inlet pipe at the outlet end of the inlet pipe, which effectively increases the discharge of exhaust gas, so that the exhaust gas can be smoothly discharged at the outlet pipe, and the exhaust gas is discharged at the outlet pipe. It will not stop, and the section of the air outlet pipe is flat and oval. This special shape of the air outlet pipe is very suitable for installation on vehicles with sufficient installation positions in the horizontal width direction and compact installation positions in the vertical height direction, and can meet the needs of special models. The air outlet pipe and the air intake pipe are also connected through a connecting ring, which effectively ensures the connection strength of the connection between the air outlet pipe and the air intake pipe, and ensures the strength of the entire decorative tailpipe assembly.

Further, the air outlet end of the air outlet pipe is formed with an inwardly rolled edge with a circular cross-section. The edge is integrated with the air outlet pipe. After the edge is installed, the strength can be increased on the one hand, and at the same time it can The air outlet end of the air outlet pipe is rounded, which is in line with the decorative effect of the tailpipe assembly. In addition, the integral structure has good overall strength.

Further, the bottom wall of the air outlet pipe is also provided with a water leakage hole, which is a rectangular hole and extends along the length of the air outlet pipe body. After the water leakage hole is set, the waste water accumulated in the exhaust gas can be discharged from the air outlet pipe. Leakage from the leakage hole will not be left behind, avoiding the corrosion of the waste water on the air outlet pipe.

Description of drawings

Fig. 1 is a schematic cross-sectional structure diagram of the decorative tailpipe assembly of the present invention.

Fig. 2 is a schematic structural view of the decorative tailpipe assembly of the present invention.

Shown in the figure of the utility model: 1 air intake pipe, 2 air outlet pipes, 2.1 crimping, 2.2 leak holes, 3 connecting rings.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in the figure, the decorative tailpipe assembly of the present utility model includes an intake pipe 1 with a circular cross section. Unlike the prior art, the decorative tailpipe assembly of the present utility model also includes a flat oval cross section. The air outlet pipe 2, the diameter of the air outlet pipe 2 is larger than the diameter of the air inlet pipe 1.

Between the described air outlet pipe 2 and the air inlet pipe 1, a connecting ring 3 with a U-shaped section is provided, the outer wall of the air outlet end of the air inlet pipe 1 is connected with the bottom wall of the connecting ring 3, and the inlet of the air outlet pipe 2 is The inner wall of the gas end is connected with the top wall of the connecting ring 3 . The connection here refers to the welding connection, and the welding connection is carried out through the connecting ring, which avoids the direct welding connection between the air inlet pipe and the air outlet pipe, and effectively increases the strength of the welding.

The air outlet end of the air outlet pipe 2 is formed with an inwardly rolled bead 2.1 with a circular cross section, and the bead 2.1 is integrated with the air outlet pipe 2 .

The bottom wall of the air outlet pipe 2 is also provided with a water leakage hole 2.2, which is a rectangular hole and extends along the length direction of the air outlet pipe 2 body.

The structural design of the decorative tailpipe assembly of the utility model is ingenious and novel, which can greatly increase the emission of exhaust gas and effectively increase the overall strength of the assembly.

In addition, the curling arrangement of the decorative tailpipe assembly of the present invention can make the decorative effect of the assembly more prominent, and the strength can also be effectively improved.
