Problems solved by technology

At present, the door will be damaged in the side impact test, which will not only increase the cost of the test, but also lengthen the cycle of each test. Therefore, it is necessary to develop a side impact test that can ensure the repeated use of the door (only damage the interior). device

Abstract

The invention discloses a car door installation tool for simulating a side collision test of a car, and the tool comprises an upper frame, an upper hinge seat, a cross swinging block, a lower hinge seat, and a lower frame. The upper and lower ends of the upper frame are provided with installation plates, and a guide rod is disposed between the installation plates. One end of the guide rod is provided with a welding block and a boss, and the other end of the guide rod is provided with a thread. The thread is provided with a nut, and the guide rod passes through the cross swinging block. The cross swinging block is connected with the upper hinge seat, and the guide rod can slide up and down in the cross swinging block. The cross swinging block can rotate around the upper hinge seat. The welding block is provided with a through hole, and the interior of the through hole is provided with a shaft. The shaft is installed on an installation block. The shaft is connected with the lower frame,and the lower frame rotates around the shaft. The lower end of the lower frame is hinged to the lower hinge seat. According to the invention, the testing trolley improves the simulation effect of theside collision test of the car, can accurately simulate the impact condition of different parts of a dummy during the side collision, and reduces the test cost.

Description

technical field [0001] The invention relates to a car door installation tool and a test trolley for a side impact test of a simulated car, and belongs to the field of passive safety of cars. Background technique [0002] Cars are one of the most important means of transportation in modern times, and the safety problems brought about by them have been paid more and more attention by people. In daily life, it is not uncommon for cars to have side collision accidents. According to statistics, in the traffic accidents that take place, side collision accidents account for about 40%, and in the accidents that cause death or serious injury, side collision accidents account for 30%-40% (data quoted from the patent automobile side collision simulation test device, disclosed No. CN 101398342A). As early as the 1980s, Western developed countries such as the United States and Europe began to formulate relevant regulations on vehicle side impact tests. In the 1990s, the United States,...
