Detailed Description

In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, the hood assembly includes a hood outer panel 1 and a hood inner panel 2. The engine hood outer panel is made of PP + EPDM + TD30, the thickness is 3.2mm, the engine hood outer panel and the engine hood inner panel are in contact position 5 through welding connection, the destructive power of each welding surface is larger than or equal to 150N, the upper flange structure 3 and the lower flange structure 3 are arranged on the edge of the engine hood and are connected with the engine hood inner panel 2 through the rivet 4, and the connection strength between the engine hood inner panel and the engine hood outer panel can be increased.

The engine hood inner plate 2 is also made of PP + EPDM + TD30, the thickness is 2.5mm, the thickness of the welding surface position between the engine hood inner plate and the engine hood outer plate is not more than 1.8, and the engine hood outer plate and the engine hood inner plate are welded at a plurality of positions in total and are connected by riveting at four positions.
