A car door installation tool and test trolley for simulating car side impact test

Abstract

The invention discloses a car door installation tool for simulating a car side impact test, which comprises an upper frame, an upper hinged seat, a cross rocker, a lower hinged seat and a lower frame. Mounting plates are installed at the upper and lower ends of the upper frame. A guide rod is installed, one end of the guide rod is installed with a welding block, one end of the guide rod is provided with a boss, the other end is provided with a thread, and a nut is installed on the thread, the guide rod passes through the cross rocker, the cross rocker and the upper hinge seat connection, the guide rod can slide up and down in the cross rocker, and the cross rocker can rotate around the upper hinge seat; the welding block is provided with a through hole, and a shaft is installed in the through hole, and the shaft is installed on the mounting block. At the same time, it is connected with the lower frame, the lower frame rotates around the axis, and the lower end of the lower frame is hinged with the lower hinge seat at the same time. The test trolley of the invention improves the simulation effect of the automobile side impact test, can accurately simulate the impact conditions of different parts of the dummy during the side impact, 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,...

AI Technical Summary

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
