Among them, the strengthening groove 1211 is arranged along the extending direction of the connecting pipe section 121. Such a setting can enhance the structural strength of the connecting pipe section 121 and ensure the stability and reliability of the connecting pipe section 121 during operation.

Such a setting can improve the utilization rate of the vehicle space, making the design more compact and the layout more convenient, and avoiding space waste. Moreover, the cross-sectional areas of the retraction section 1221, the transition section 1222, and the expansion section 1223 are all equal to the cross-sectional area of the connecting pipe section 121. Such a setting can ensure the same flow rate in the avoidance pipe section 122 while ensuring the utilization rate of the vehicle space, so that the flow rate of the avoidance pipe section 122 meets the preset flow rate value.

Among them, one of the two first pipeline structures 11 has a positioning groove 111, and the other has a positioning protrusion 112.

With such a setting, it can play a role in positioning and guiding during connection; the first connecting plate 31 is abutted against the bottom of one first pipeline structure 11, the second connecting plate 32 is abutted against the top of the other first pipeline structure 11, and at the same time, the first connecting plate 31 and the second connecting plate 32 are connected by the first fastener 33, so as to achieve the purpose of connecting the two first pipeline structures 11.

[0045] Or, one end of the first connecting plate 31 is clamped with one end of the second connecting plate 32, and the other end of the first connecting plate 31 and the other end of the second connecting plate 32 are connected by the first fastener 33.

[0046] Optionally, both of the two first pipeline structures 11 have installation grooves, and both the first connecting plate 31 and the second connecting plate 32 are located in the installation grooves.

The first backing plate is located between the first connecting plate 31 and the installation groove of one first pipeline structure 11, and the second backing plate is located between the second connecting plate 32 and the installation groove of the other first pipeline structure 11.

[0048] In this embodiment, both of the two connecting pipe segments 121 are provided with positioning blocks 1213. The positioning block 1213 of one connecting pipe segment 121 is connected to the positioning block 1213 of the other connecting pipe segment 121, thus ensuring the reliable connection of the two connecting pipe segments 121. At the same time, the second connecting member 4 includes a first fastening plate 41, a second fastening plate 42 and a second fastener 43. The first fastening plate 41 is abutted against the bottoms of the two connecting pipe segments 121, and the second fastening plate 42 is abutted against the tops of the two connecting pipe segments 121.
