Description

Technical Field

[0001] The utility model belongs to the field of precision sheet metal chassis, in particular to a precision sheet metal chassis with an integrated structure. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body), etc. Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. As the name suggests, a precision sheet metal chassis is a precision sheet metal chassis prepared by precision sheet metal. For example, the application number: CN201420814765.4 is a universal sheet metal chassis, which consists of four sheet metal parts: a front panel, a rear panel, a bottom panel and a cover panel, which are connected to each other by screws. The bottom panel and the cover panel are designed as a U-shaped structure, which are connected to each other by Z-shaped folding edges arranged on both sides of the bottom panel. The height of the Z folding edge is slightly greater than the thickness of the cover panel. A right-angle folding edge is provided on the front edge of the bottom panel and the cover panel to connect to the front panel, and a right-angle folding edge is provided on the upper edge and both sides of the rear panel to connect to the cover panel. The existing precision sheet metal chassis is formed by splicing multiple sheet metal plates together, and then the multiple sheet metal plates are welded together.
