[0002] Sheet metal is a processing technology. Sheet metal does not yet have a relatively complete definition. When producing automobiles, a large number of sheet metal parts need to be connected. Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, welding, riveting, splicing, and forming. It is very necessary for automobile sheet metal parts to rely on their own structure to increase the stability of the structure. The front and rear sides, top and chassis of the car all need sheet metal parts for protection and wrapping. The sheet metal parts used for existing automobile chassis protection are called chassis armor.

[0003] Most of the existing chassis armors need to be customized according to the model and specifications of the car. Vehicles of the same type also need to be customized and punched according to the installation holes reserved in the chassis, which reduces the versatility of chassis armors on the market and reduces the scope of application. In addition, the existing chassis armors on the market are only a thin layer. During use, hard objects such as stones flying from the road surface collide with them and produce noise, thereby affecting the driving comfort of the vehicle. For this reason, we have proposed an automobile protective sheet metal. Utility Model Content
