Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to a vehicle door assembly. Background technique

[0002] The existing design of water cutting outside the waistline of the vehicle body has the following problems:

[0003] 1. The traditional water cutting scheme: the outer sheet metal hemming process and structure lead to a large Z-direction difference in the appearance of the outer water cutting, generally greater than 15mm. The main reason is that its installation structure is restricted by the sheet metal hemming and technology, which cannot meet the high quality of the shape. Feeling "flat" needs, unable to cater to the trend of high-end charm;

[0004] 2. Flat water cutting of some high-end brands: it solves the problem of large Z-direction step difference, but the waistline adopts laser welding, which requires a large investment and high cost for the production line.

[0005] Therefore, it is necessary to design a car ...
