The installation frame 4 adopts a profile structure and is welded to the inner surface of the vehicle body 1 at the opening 3. A mounting seat 5 is provided on the back of the through-piece 2 to be installed, and the mounting seat 5 is also welded to the back of the through-piece 2. When the through-piece 2 is installed, the mounting seat 5 is extended into the inside of the opening 3 and fixedly connected to the mounting frame 4.
[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting frame 4 adopts an annular structure and is fixed to the inner surface of the vehicle body 1 by full circumferential welding to ensure the sealing between the mounting frame 4 and the vehicle body 1, and a plurality of first mounting holes 43 are opened on the mounting frame 4 for fixed connection with the mounting seat 5.
[0037] like Figures 3 to 5 As shown, in this embodiment, the mounting seat 5 preferably adopts a structure that is intermittently arranged along the circumference of the through-piece 2, and the mounting seat 5 is only arranged at the connection point that needs to be fixedly connected with the mounting frame 4, such as six mounting seats 5 are welded on the back of the through-piece 2, and a second mounting hole 52 is arranged on each mounting seat 5, and the mounting frame 4 is fixedly connected through multiple mounting seats 5. Of course, the mounting seat 5 adopts a continuous annular structure along the circumference of the through-piece 2, and multiple second mounting holes 52 are opened on the annular mounting seat 5.
[0038] like Figure 2 and Figure 5 As shown, in this embodiment, preferably, the mounting frame 4 adopts an F-shaped cross-section structure, including a first mounting edge 41 and a second mounting edge 42 extending from the outside to the inside and both extending toward the center, and the length of the first mounting edge 41 in the radial direction is shorter than the length of the second mounting edge 42 in the radial direction. In this way, during installation, the convenient mounting seat 5 can be extended into the interior of the mounting frame 4, and can smoothly pass over the first mounting edge 41 and be fixedly connected to the second mounting edge 42 on the inner side.
[0039] like Figure 4 and Figure 5 As shown, in this embodiment, preferably, the mounting seat 5 adopts an L-shaped structure in cross section, has a third mounting edge 51 extending radially at the inner end, the mounting seat 5 is placed in the mounting frame 4, and the third mounting edge 51 is fixedly connected with the second mounting edge 42 of the mounting frame 4 inside the opening 3. Further preferably, the third mounting edge 51 extends toward the center, which makes it more convenient to fix the mounting seat 5 with the mounting frame 4.
