[0033] According to the first aspect of the present application, a double cross pipe is provided, as shown in the figure, which is used in the exhaust system of a vehicle, and comprises a first air inlet 1, a second air inlet 2, a first air outlet 3, and a second air outlet 4. Figures 1 to 10

[0034] In the following description, reference will be made to Figures 1 to 10 ​The detailed structure of the first air inlet 1, the second air inlet 2, the first air outlet 3 and the second air outlet 4 of the double-cross pipe is specifically described.

[0035] As shown in the embodiment, the first air inlet 1 and the second air inlet 2 are arranged opposite to the first air outlet 3 and the second air outlet 4, and the line between the first air inlet 1 and the second air outlet 4 is arranged crosswise to the line between the second air inlet 2 and the first air outlet 3, that is, the lines between the first air inlet 1, the second air inlet 2, the first air outlet 3 and the second air outlet 4 form an X shape. Figure 1 Further, the first air inlet 1, the second air inlet 2, the first air outlet 3 and the second air outlet 4 each include a plurality of air paths, which means that the four through holes include air paths arranged in different directions for gas flow inside the first air inlet 1, the second air inlet 2, the first air outlet 3 and the second air outlet 4. The plurality of air paths can make the gas flow in different directions to improve the exhaust efficiency and at the same time make the exhaust system have excellent sound wave effect.

[0036] Further, at least one air path of the first air inlet 1 is connected to at least one air path of the second air outlet 4, and at least one air path of the second air inlet 2 is connected to at least one air path of the first air outlet 3. The air paths arranged in this way can significantly improve the exhaust efficiency, and at the same time can cut the exhaust sound wave form to make the sound wave high-frequency surge. The air paths arranged in different directions can combine and communicate the two parallel exhausts and balance the flow, and the exhaust pressure can be adjusted according to different pipe designs.

[0037] The double-cross pipe connects the two parallel exhaust pipes in a cross and combined manner through the first air inlet 1, the second air inlet 2, the first air outlet 3 and the second air outlet 4, and through the cross arrangement of the first air inlet 1 and the second air outlet 4 and the second air inlet 2 and the first air outlet 3, the exhaust efficiency can be improved. At the same time, the plurality of air paths connected in different directions can combine and communicate the two parallel exhausts and balance the flow, and the exhaust pressure can be adjusted according to different pipe designs, and the exhaust sound wave form can be cut to make the sound wave high-frequency surge.

[0038] Preferably, in the embodiment, the double-cross pipe provides three embodiments for reference according to different vehicle models and different installation spaces.

[0039] Preferably, as shown in the embodiment, the double-cross pipe can be applied to different vehicle models and different installation spaces.

Specifically, in addition to being connected with the second air outlet 4 through the first branch pipe 5, the first air inlet 1 is also connected with the first air outlet 3 through a second branch pipe 6, so that the airflow passing through the first air inlet 1 can be discharged through the first air outlet 3 and the second air outlet 4 respectively. Similarly, in addition to being connected with the first air outlet 3 through the third branch pipe 7, the second air inlet 2 is also connected with the second air outlet 4 through a fourth branch pipe 8. Such a configuration makes the gas entering from the first air inlet 1 and the second air inlet 2 can be discharged through the first air outlet 3 and the second air outlet 4. Such a configuration can improve the flowability of the airflow, and also make the sound waves high-frequency and vigorous.

[0041] Preferably, as shown in the first embodiment, in order to achieve a more excellent connection with the exhaust system of the vehicle, while adapting to the vehicles in the prior art, the first air inlet 1 and the second air inlet 2 are arranged in parallel, and the first air outlet 3 and the second air outlet 4 are arranged in parallel.

In actual use, users can choose an appropriate distance between the first air inlet 1 and the second air inlet 2, and an appropriate distance between the first air outlet 3 and the second air outlet 4, depending on the vehicle model, installation position, and space.

[0048] Preferably, such as Figures 7 to 10 As shown, in the third embodiment, the difference between the double-cross pipe of the third embodiment and the double-cross pipes of the first and second embodiments is that: the first air inlet 1 is connected to the second air inlet 2 through the first branch pipe 5, and the first air outlet 3 is connected to the second air outlet 4 through the third branch pipe 7.
