The car airbag is an important protection device in the passive safety protection of the car, and the co-driver airbag has basically become the standard of the car. When the co-pilot airbag is working, the air bag is inflated through the gas inflator, and the air bag is deployed after inflation to achieve the purpose of protecting the occupant. Today's new energy vehicle co-driver position will design a large display that runs through the entire co-driver position and is higher than the surface of the instrument panel, which affects the expansion of the airbag.
The shape and folding method of the air bag have a great impact on the expansion effect, and the air bag should be close to the instrument panel and the display screen to achieve a better protection effect. At the same time, the folding method of the air bag is also particularly important. At present, the co-pilot airbag has two folding methods: one is mechanical extrusion folding, which is to squeeze the air bag into the shell through the control of the mechanical arm; The other is manual tooling folding, which is folded by hand with the separator.
The form of mechanical extrusion folding is relatively fixed, it is difficult to have large changes, and the air bag is developed quickly and the impact force is large, which can not meet all the test requirements. Manual tooling folding can adjust the expansion speed of the air bag and the impact is small, the biggest feature is that the attitude of the air bag can be adjusted to meet the collision requirements of different models.
