Abstract: The door horizontal overload is mainly aimed at the misoperation of the door user, although it is rare. However, if the door has been held for many times, resulting in poor performance or even failure to close the door, customers will complain about the quality and performance of the product. In the paper, the local models including the upper and lower hinges of the tailgate are established respectively, and the optimization scheme of the upper and lower hinges of the tailgate is obtained quickly. Then, the rationality of the optimization scheme is further verified by the simulation and experiment of the tailgate horizontal overload. The simulation and test results show that the upper and lower hinges of the tailgate are also designed to meet the requirements for the horizontal overload performance of the tailgate.
