Problems solved by technology

However, there is a risk of rain leakage in the forming process of the above-mentioned sheet metal end, because after cutting and manual bending, it is easy to form a gap at the convex point 7' of the sheet metal end, causing rainwater to easily flow in from the gap Cargo compartment; In addition, since the top cover skin is welded in blocks, when it is welded to the cargo compartment assembly at 3', a gap will be formed between the top cover skin assembly and the cargo compartment assembly at the overlapping position 8', resulting in rain leakage and corrosion problems, causing serious troubles to customers

Abstract

The invention provides a top cap assembly of a van-type cargo compartment. The top cap assembly is formed by sequentially overlapping and welding front skin, middle skin and rear skin from front to rear along the front-rear direction of a vehicle body, and each of the front skin, the middle skin and the rear skin is integrally formed by adopting sheet metal parts by a die through punching, so that cracking at ends of sheet metal due to adoption of shearing and bending processes are avoided; by designing waterproof groove structure and step structure, compared with the prior art, the top cap assembly has the advantages that rain leakage and rusting are avoided, so that sealing performance and waterproof performance of the top cap assembly are improved integrally.

Description

technical field [0001] The invention belongs to the field of automobile bodies, in particular to a top cover assembly of a box-type cargo compartment. Background technique [0002] With the country's promotion of closed logistics transportation, vans are widely used in urban logistics. At present, compared with being picky about the appearance quality of the roof assembly of the cargo compartment, customers cannot tolerate the occurrence of rain leakage in the cargo compartment. [0003] The structure of the existing box-type cargo compartment top cover assembly is as follows: figure 1 As shown, the partial enlarged view of the overlapping joint C of the two skins and the end view of the overlapping structure of the top cover skin and the cargo box assembly are shown in figure 2 and image 3 , the first piece of top cover skin 1' and the second piece of top cover skin 2' are overlapped and welded to form a top cover assembly, and the obtained top cover assembly can be pl...
