In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; "multiple" and "several" refer to two or more. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "connect", and "connected" should be understood in a broad sense, and their specific settings and connection methods can be set according to specific circumstances without specific restrictions. For ordinary technicians in this field, their specific meanings in the present invention can be understood according to specific circumstances.

[0042] Reference below Figure 1-17 The vehicle through-tunnel and the vehicle provided with the through-tunnel provided in the embodiments of the present invention are described in detail.

[0043] like Figure 1-4 As shown, a through-passage of a vehicle provided according to an embodiment of the present invention comprises:

[0044] A bellows assembly, wherein the bellows assembly comprises an outer bellows assembly 1 and an inner bellows assembly 2, wherein the inner bellows assembly 2 is arranged inside the outer bellows assembly 1 and forms a cavity between the inner bellows assembly 2 and the outer bellows assembly 2, wherein the inner portion refers to an inner space enclosed by the outline of the outer bellows assembly 1;

[0045] The coupler load-bearing component 6 is suitable for connecting with the coupler of the vehicle, and the coupler load-bearing component 6 is fixed to the inner side of the lower end of the outer bellows component 1, and the inner side of the lower end of the outer bellows component 1 refers to the inner side wall of the lower end of the outer bellows component 1, and the coupler can be installed on the coupler load-bearing component 6. This design not only allows the coupler load-bearing component 6 to support the coupler, but also allows the coupler to exert an upward pulling force on the entire through passage, and this way of the coupler pulling up the through passage can make the through passage more stable and less noisy.

[0046] like Figure 1 As shown, according to an embodiment provided by the present invention, the bellows assembly also includes a plurality of first connecting brackets 7 and a plurality of second connecting brackets 8 located in the cavity, and the inner bellows assembly 2 and the outer bellows assembly 1 are connected via the plurality of first connecting brackets 7 and the plurality of second connecting brackets 8. The provision of the first connecting brackets 7 and the second connecting brackets 8 makes the connection between the inner bellows assembly 2 and the outer bellows assembly 1 more convenient, and at the same time makes the entire bellows assembly more compressible and more stable.

[0047] Here, if Figure 1-4 As shown, the outer bellows assembly 1 and the inner bellows assembly 2 are both formed by sewing a plurality of U-shaped bellows cloths, so a plurality of first connecting brackets 7 and second connecting brackets 8 are required to connect the inner bellows assembly 2 and the outer bellows assembly 1 to ensure the connection strength between the two and the strength of the entire bellows assembly. Figure 1 As shown, one end of the first connecting bracket 7 can be connected to the upper side of the inner bellows assembly 2, and the other end can be connected to the inner side of the upper end of the outer bellows assembly 1, and one end of the second connecting bracket 8 can be connected to the lower end of the inner bellows assembly 2, and the other end can be connected to the left and right inner side walls of the outer bellows assembly 1 and close to the lower end of the outer bellows assembly 1. Here, along the front-to-back direction, the distance between each adjacent two first connecting brackets 7 connected between the outer bellows assembly 1 and the inner bellows assembly 2 and the distance between each adjacent two second connecting brackets 8 can be equal, so that the force between the inner bellows assembly 2 and the outer bellows assembly 1 is uniform.

[0048] like Figure 1-3 As shown, according to an embodiment provided by the present invention, the first connecting bracket 7 can be set to an "L" shape, and its "L"-shaped vertical end can be connected to the upper inner wall of the outer bellows assembly 1, and the "L"-shaped horizontal end can be connected to the outer side wall of the inner bellows assembly 2 and close to the upper end position of the inner bellows assembly 2. Of course, the connection can also be reversed while ensuring the connection strength and other performances. Setting the first connecting bracket 7 to an "L" shape can facilitate the installation and fixation of the first connecting bracket 7 when assembling with the outer bellows assembly 1 and the inner bellows assembly 2, and the stability of the connection is better.

[0049] like Figure 1 , Figure 2 , Figure 3 , Fig.11 , Fig.12 As shown, according to an embodiment of the present invention, each of the second connecting brackets 8 includes a first end 81 and a second end 82 connected at an obtuse angle. Here, it should be noted that Fig.12 , 13 For the convenience of description, the first end 81 is defined as an end connected to the outer bellows component 1, and the second end 82 is defined as an end connected to the inner bellows component 2, so Fig.12 and Fig.13The two identical structures are marked with different serial numbers 81 and 82, wherein 81 is the first end connected to the outer bellows assembly 1, and 82 is the second end connected to the inner bellows assembly 2. The obtuse angle bending connection means that the angle formed between the outer contours of the first end 81 and the second end 82 is an obtuse angle. Such a structure can facilitate the connection between the inner bellows assembly 2 and the outer bellows assembly 1, and the connection stability is better.

[0050] like Figure 1-3 As shown, according to an embodiment provided by the present invention, a plurality of second connecting brackets 8 are arranged horizontally and longitudinally at intervals in the cavity formed by the outer bellows assembly 1 and the inner bellows assembly 2. The plurality of second connecting brackets 8 are arranged horizontally and longitudinally at intervals, so that the force on the bellows assembly is more uniform, and the risk of bending deformation or fracture failure of the bellows due to uneven force between the inner bellows assembly 2 and the outer bellows assembly 1 is avoided. Here, the horizontal longitudinal direction refers to the front-back direction in the horizontal plane.

[0051] like Figure 1-3 , Fig.15 and Figure 5-6 As shown, according to an embodiment provided by the present invention, in the up-down direction, the second ends 82 of all the second connecting brackets 8 are arranged flush, the first ends 81 of each two adjacent second connecting brackets 8 are arranged alternately, and the lower surface of the first end 81 located on the upper side is higher than the upper surface of the first end 81 located on the lower side. When the vehicle turns, the outer bellows assembly 1 on the turning side will be compressed, at this time, the first ends 81 of the second connecting brackets 8 fixed on the outer bellows assembly 1 will be close together, if the first ends 81 of several second connecting brackets 8 fixed on the outer bellows assembly 1 are fixed on the same horizontal line in the front-to-back direction, the first ends 81 of the two adjacent second connecting brackets 8 will be close together, resulting in interference, so that the compressibility of the entire through-passage is greatly reduced, thereby increasing the turning radius of the vehicle. Therefore, here, the first ends 81 of the first connecting brackets 8 fixed on the outer bellows assembly 1 are staggered, and the lower surface of the first end 81 located on the upper side is located higher than the upper surface of the first end 81 located on the lower side, that is, one end of the adjacent second connecting brackets 8 fixed on the outer bellows assembly 1 is staggered up and down to avoid interference between the two adjacent second connecting brackets 8 when the vehicle turns, thereby increasing the compressibility of the bellows assembly and reducing the turning radius of the vehicle.

[0052] like Figure 2-3As shown in Figures 11-15, according to an embodiment provided by the present invention, the first connecting bracket 7 and the second connecting bracket 8 are fixed to the inner bellows assembly 2 and the outer bellows assembly 1 by means of a connecting clip 13.
