Each of the fairing spliced plates is provided with a set of top support bases 3 between the fairing spliced plate and the roof panel 1, and all the top support bases 3 are linearly distributed along the longitudinal direction of the vehicle body at equal intervals.

[0032] The top fairing 2 and the upper support plate 31 are detachably connected by bolts. The fixed mounting hole is a square through hole which penetrates along the thickness direction of the top fairing 2. The edge of the upper support plate 31 can be integrally provided with a limiting boss which is abutted with the fixed mounting hole along the vertical direction of the vehicle body, so as to limit the position of the top fairing 2 along the vertical direction of the vehicle body, and ensure that the top fairing 2 is reliably fixed on the upper support plate 31.

[0033] As shown in the accompanying drawings, Figure 1 The upper support plate 31 and the antenna mounting seat 4 are also arranged in a sunken manner. Specifically, the upper surface of the upper support plate 31 is formed with a positioning groove, and the bottom of the antenna mounting seat 4 is provided with a positioning protrusion. The positioning groove and the positioning protrusion are in concave-convex cooperation along the vertical direction of the vehicle body, so as to limit the movement of the antenna mounting seat 4 relative to the upper support plate 31. In addition, the antenna mounting seat 4 is rectangular, and each of the four corners of the antenna mounting seat 4 is provided with a fastening bolt. The fastening bolt is used to fix the antenna mounting seat 4 on the upper support plate 31. Of course, the fixing mode of the antenna mounting seat 4 is not limited to this.

The first reinforcing rib is opposite to the second reinforcing rib 3323, that is, the first reinforcing rib is arranged on the side of the first bearing plate 331 facing the second bearing plate 332, and the second reinforcing rib 3323 is arranged on the side of the second bearing plate 332 facing the first bearing plate 331. The first reinforcing rib and the second reinforcing rib 3323 can be triangular reinforcing ribs fixed by welding, but are not limited thereto. Of course, reinforcing ribs can also be additionally arranged between the first bearing plate 331 and the lower support plate 32 and between the second bearing plate 332 and the lower support plate 32, so as to improve the connection strength between the lower support plate 32 and the bearing frame 33 and improve the stability of the top support seat 3.
