Problems solved by technology

However, since the structure of the curved part is between a quarter circle and a half circle, such as Figure 4 As shown by the middle arrow, high-temperature impurities will fall on the top of the gas generator. Due to the strong impact of the gas, a small number of high-temperature impurities are prone to rebound, even if they act on the top of the airbag buffer, corrosion holes will still be generated
With the existing structure, it cannot completely prevent the high-temperature impurity from corroding the airbag buffer

Embodiment 1

[0023] Such as figure 1 , figure 2 and image 3 A safety airbag structure for a car following is shown, including a guard ring and a gas generator located in the guard ring, and the guard ring includes a blocking sill 1 and is located on the blocking sill 1 so that high-temperature impurities do not The curved part 2 dropped onto the gas generator, the inner surface of the curved part 2 is provided with a high-temperature impurity adsorption layer 3 .

[0024] This embodiment has made improvements in the prior art, so that high-temperature impurities will not fall on the gas generator, that is, high-temperature impurities will not bounce back on the gas generator and act on the airbag buffer 4, which can completely Prevent high-temperature impurities from corroding the airbag buffer. The high-temperature impurity adsorption layer 3 continuously adsorbs the high-temperature impurities 5 during the discharge process, reduces the amount of high-temperature impurities during ...

Embodiment 2

[0026] Such as figure 1 The shown airbag structure for following cars is refined on the basis of Embodiment 1, that is, the diameter of the curved portion 2 gradually decreases from the end connected to the barrier 1 to the end, and The opening at the end is upwards. In this embodiment, the structure of the curved part is refined, that is, a structure that bends inward, the diameter gradually decreases, and the opening is upward. figure 1 In the direction shown in , finally, in the bending part, that is, it will not fall on the gas generator and rebound, which can completely prevent the high temperature impurity from corroding the airbag buffer. The gas impulsive force released by the gas generator is large, and the integrated structure ensures the stability of the structure to resist the strong impact of the gas.

Embodiment 3

[0028] Such as figure 2 and image 3 The airbag structure shown for a car following is refined on the basis of Embodiment 1, that is, the curved portion 2 includes a first curved portion 21 fixed on the sill 1 and connected to the second A curved portion 21 cooperates with a second curved portion 22 that prevents high-temperature impurities from falling on the gas generator. The first curved portion 21 is not less than half of the arc, and the first curved portion 21 and / or the second bent portion 22 is provided with a high-temperature impurity adsorption layer 3 .

[0029] The opening formed by the second bending portion 22 is upward.

[0030] The diameter of the second curved portion 22 is smaller than the diameter of the first curved portion 21 .

[0031] In this embodiment, the structure of the curved part is refined, that is, the curved part is arranged in separate parts, and the split structure of the first curved part and the second curved part is adopted, which is ...

Abstract

The invention discloses a safety airbag structure for a car following, which comprises a guard ring and a gas generator located in the guard ring. To the curved part on the gas generator, the inner surface of the curved part is provided with a high-temperature impurity adsorption layer, which can completely prevent the high-temperature impurity from corroding the airbag buffer.

Description

technical field [0001] The invention relates to the field of safety airbag equipment, in particular to a safety airbag structure for a car following a car. Background technique [0002] Since the car was born at the end of last century, it has gone through more than 100 years of ups and downs. Car-following is the driving state in which the vehicle behind follows the vehicle in front when vehicles line up on a single lane, that is, the vehicle in front and the vehicle in the rear achieve information communication. Automated driving is realized by following the car driving scheme. The airbag is to reduce the damage to the driver and passengers caused by the huge inertia when the car has a frontal collision, so the airbag is very important for the following car. [0003] The airbag generally includes an outer cover, a gas generator, and an airbag cushion. The airbag cushion is opened by the deployment gas supplied by the gas generator. The gas generator processes the deploy...
