Description

Technical Field

[0001] The utility model relates to the technical field of side curtain airbag testing, in particular to a side curtain airbag impact testing device. Background Art

[0002] The side curtain airbag is composed of but not limited to airbags, gas generators, connecting devices, labels and other auxiliary parts, and is generally installed on the left and right sides of the vehicle roof. When the vehicle is involved in a side collision or rollover accident while driving, the gas generator receives an ignition command to ignite the gas generator, which is usually based on chemical substances such as sodium nitride (NaN3) to ignite the gas. These substances produce a large amount of nitrogen (N2) during the combustion process, and the generated nitrogen is quickly filled into the side curtain airbag, causing it to expand and deploy in a very short time, forming a buffer area to reduce the damage to passengers in side collisions or rollover accidents.

[0003] As one of the important accessories for automobile safety performance, side curtain airbags are usually subjected to linear impact tests during automobile performance tests to verify whether the side curtain airbags can effectively absorb the energy of head impact during a collision.

[0004] For linear impact testing, the industry currently mainly uses profiling tooling for impact test verification, but the profiling tooling can only be applied to a single specific model of side curtain airbags and it is difficult to adjust the fixed position. That is, for different models of side curtain airbags, the length, width and installation angle of the side curtain airbags are different, and each test parameter is different. Each time a different model of side curtain airbag is tested, the test parameters need to be adjusted, and different profiling tooling needs to be modified to adapt to different side curtain airbags, resulting in low test efficiency and high cost.

[0034] Specifically, a plurality of adjustment rods 4 are arranged along the first direction and each adjustment rod 4 can be connected to any of the connection positions 31, and the plurality of adjustment rods 4 are used to connect to the side curtain airbag. The side curtain airbag has a plurality of connection ends for installation on a car. The plurality of connection ends are arranged at intervals along the first direction, and the two outermost connection ends along the first direction among the plurality of connection ends are substantially the same length as the side curtain airbag, and the two outermost connection ends along the first direction among the plurality of connection ends need to be connected to the two outermost adjustment rods 4 along the first direction among the plurality of adjustment rods 4, that is, the spacing between the two outermost adjustment rods 4 along the first direction needs to be adapted to the length of the side curtain airbag. In addition, two adjacent connection ends also need to be connected to two adjustment rods 4, and the spacing between the plurality of adjustment rods 4 also needs to be adapted to the spacing between the plurality of connection ends.

[0035] In the market, the length of each side curtain airbag may be different, but the spacing of the multiple adjustment rods 4 along the first direction of the utility model can be adjusted, that is, it can adapt to side curtain airbags of different lengths. The number of multiple connection ends of each side curtain airbag is different, and the spacing of the multiple connection ends is also different. The multiple adjustment rods 4 of the utility model can adjust the installation position of the multiple adjustment rods 4 and the connection rod 3 according to the spacing of the multiple connection ends to adapt to various models of side curtain airbags.
