A front apron reinforcing cross beam is transversely arranged in the middle of the plate surface of the front apron, and the front apron reinforcing cross beam is fixedly attached to the front apron according to the plate surface characteristics of the front apron. However, there are certain limitations in the reinforcing structure of the front apron cross beam of the automobile, such as insufficient strength and poor corrosion resistance. These problems may cause deformation, damage or even fracture of the connecting plate during use, thereby affecting the safety performance of the whole vehicle. Therefore, a connecting plate structure of a front apron reinforcing beam of an automobile is needed. Content of the Utility Model
