[0002] At present, the new energy industry is booming. Cars are not just a means of transportation. The requirements for intelligence and technology are getting higher and higher. For example, adding a refrigerator to the auxiliary instrument panel is a must-have configuration option for new energy vehicles. This has greatly increased the overall weight of the auxiliary instrument panel, requiring the connection between the auxiliary instrument panel assembly and the body bracket to be stronger and more robust. The existing connection with the body bracket is mostly the bolt assembly hole of the auxiliary instrument panel body. The traditional method is direct injection molding, but according to the current development of the interior decoration industry, the injection molding holes have the problem of insufficient abuse force and poor durability. Based on the requirements for the strength of the assembly holes, there is currently a solution using metal insert injection molding, but this design has limited ability to absorb the body assembly tolerance. Therefore, it is necessary for us to improve such a structure to overcome the above defects. Utility Model Content
