Description

Technical Field

[0001] The utility model relates to the technical field of airbag safety tests, and particularly relates to a new type of airbag blasting fixture vehicle. Background Art

[0002] With the development of society, the application of automobiles has increased year by year. While people pursue high-quality automobile services, they pay more attention to the safety performance of automobiles. The airbag system is a passive safety protection system. It is used in conjunction with the seat belt and can provide effective protection for occupants when a vehicle collides. When a car collides, the airbag in the car can reduce the head injury rate by 25% and the facial injury rate by about 80%. Airbags are generally located on the steering wheel, upper part of the co-driver glove box, A-pillar, B-pillar, C-pillar, and seats. The airbag plays a role in protecting the passengers in the car during an accident. The airbag generally buffers the important parts of the passengers in the car. Before a car is launched on the market, it is necessary to detect the performance of the airbags configured on the car. For example, the time for the airbag to reach the designated position during a collision. If the airbag deploys too early or too late, it will not be able to protect the passengers in the car. Therefore, the test to detect whether the airbag deploys to the designated position within the specified time is very important.

[0003] Generally, the fixture vehicles used in airbag blasting tests are dedicated to specific models. When there are many vehicle models, the number of fixture vehicles is huge, and a large amount of storage space is required for storage. Moreover, when conducting seat airbag blasting tests on different vehicle models, it is necessary to switch the fixture vehicles, and the operation time is too long, which is not universal.

[0004] At present, some universal fixture vehicles have also appeared on the market, but they can only perform simple horizontal or vertical movements, and the moving structure is relatively simple. Problems such as jamming or limited stroke often occur, and true universality cannot be achieved. Content of the Utility Model
