[0002] Blue-plate vehicles are subject to the weight limit of the chassis. In order to achieve qualified vehicle preparation, the upper body needs to be designed to be lightweight. For flatbed trucks, the weight of the bottom plate accounts for 60%-70% of the total weight of the upper body, and for vans it accounts for about 1 / 3. Therefore, reducing the weight of the bottom plate through structural optimization is the most effective means to lightweight the upper body. At present, the mainstream bottom plates in the industry have two lightweight structures: deep corrugated bottom plates and shallow corrugated pattern bottom plates. When using a deep corrugated bottom plate, a weight reduction of 54kg can be achieved, but because the thickness of the bottom plate body is only 1.0mm, this structure is only suitable for loading light cargo; when using a shallow corrugated pattern bottom plate, the weight reduction can be 13kg, and the reduction is limited.
