Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a perspective view of the entire vehicle, and a schematic section a-a. Fig. 2 shows an exploded view of the whole vehicle, which shows the vehicle body 1, the skateboard chassis 3, and the skateboard seal strip 2 arranged between the vehicle body 1 and the skateboard chassis 3.
As shown in figure 3, a metal wire 4 is arranged in the sliding plate chassis sealing strip 2, so that the sealing strip is prevented from shrinking in the length direction, and the length stability of the sealing strip is improved. The bottom of the sliding plate chassis sealing strip 2 is provided with a convex feature 2e, the convex feature 2e is embedded into a concave feature 3b of the sliding plate chassis 3, the convex feature 2e is provided with tooth profile features 2ea and 2eb, and the tooth profile features 2ea and 2eb are in interference fit with the concave feature 3b, so that the connection of the sliding plate chassis sealing strip 2 and the sliding plate chassis 3 is realized.
