Abstract

The invention discloses a test bench for the comprehensive test of an automotive safety airbag. The test bench comprises a test bench mechanical part which consists of an automotive safety airbag unfolding speed and acceleration testing buffer device, an automotive safety airbag counteracting force testing device and a test stand. The test stand comprises a test stand lower bracket and an automotive safety airbag static unfolding and lifting device; the automotive safety airbag static unfolding and lifting device is mounted at one side of a test bench face of the test stand lower bracket, the automotive safety airbag unfolding speed and acceleration testing buffer device is mounted at the upper end of the automotive safety airbag static unfolding and lifting device, and the automotive safety airbag counteracting force testing device is mounted on the test bench face in front of the automotive safety airbag static unfolding and lifting device; and locking guide rails and pressing plates are vertically mounted on inner side end faces of a left side supporting frame and a right side supporting frame in the automotive safety airbag counteracting force testing device, and guide plates and locking guide rails in the automotive safety airbag static unfolding and lifting device are in sliding connection with the pressing plates in a matching manner.

Description

technical field [0001] The invention relates to a test device for testing and analyzing automobile safety airbags. More specifically, the present invention relates to a comprehensive test bench for automobile airbags that records the static deployment process of automobile airbags through data and images, and analyzes and verifies the performance of automobile airbags through the collected data. Background technique [0002] With the rapid increase of the number of automobiles and the increase of vehicle speed, traffic accidents have become frequent and serious, and people have paid more and more attention to the safety of automobiles. The airbag is a safety system that complements the restraint system and the three-point safety belt. Its function is to reduce the secondary collision damage caused by the huge inertial force caused by the collision, ease the impact on the occupants and absorb the collision energy, so as to protect the safety of the occupants. . Airbags are ...
