In the hinge reinforcing plate structure of the engine hood, the first mounting part is further connected with a connecting part used for being connected with an outer plate of the engine hood, and the connecting part is provided with a rubber groove. Because many places are cavity structures between engine bonnet planking and the engine bonnet inner panel, have the disadvantage in the aspect of the noise, this application is equipped with gluey groove through setting up connecting portion and connecting portion, and glue the technology through the inflation between the engine bonnet planking and realize being connected, has increased the indirect connection of an engine bonnet planking and engine bonnet inner panel in other words, has compensatied the defect of this department, has improved the NVH performance.
In the hinge reinforcing plate structure of the engine hood, the connecting part and the reinforcing rib are located on the same side of the body, and the connecting part and the body are integrally formed. The manufacturing is convenient and the cost is low.
Compared with the prior art, this engine bonnet's hinge reinforcing plate structure has following advantage:
1. the reinforcing ribs, the first flanging and the second flanging are arranged in a matched mode, so that the rigidity and the strength of the body in all directions can be greatly improved.
2. On the premise of ensuring the requirements on rigidity and strength, the size of the first mounting part can be optimized and reduced, and the light design goal is realized.
3. Through setting up connecting portion and being equipped with gluey groove on the connecting portion, glue the technology through the inflation and realize being connected between and the engine bonnet planking, increased the indirect connection of a department engine bonnet planking and engine bonnet inner panel in other words, remedied the defect of this department, improved the NVH performance.
