Problems solved by technology

[0002] like figure 1 As shown, in general, the fixed and reinforced structure of the automobile airbag is composed of the following parts, the airbag reinforcement frame 1, the airbag door 2, and the airbag hinge 3, which are integrally injection-molded with thermoplastic polyolefin (TPO) material However, the cost of TPO material is high, and its high temperature performance is not as good as that of metal. TPO injection molded hinges are likely to be broken at high temperatures
another such as figure 2 As shown, the airbag door 5 and the airbag reinforcement frame 4 are two independent parts, which are connected and fixed by means of screws, bolts 6 or blind rivets 7, etc. However, this connection method is inconvenient to install, and the airbag door 5 Easy to separate and fall off from the airbag reinforcement frame 4

Abstract

The invention discloses an automobile air bag fixing and reinforcing structure, which comprises an air bag reinforcing frame, at least one air bag door and air bag hinges in one-to-one correspondence to the air bag doors. Each air bag hinge comprises a portion embedded into the corresponding air bag door and the other portion embedded into the air bag reinforcing frame, and the two portions are connected with each other through a bent portion. The automobile air bag fixing and reinforcing structure is low in cost, stable in high-temperature performance, convenient in mounting, firm and reliable.

Description

technical field [0001] The invention relates to a fixing and strengthening structure of an automobile airbag. Background technique [0002] Such as figure 1 As shown, in general, the fixed and reinforced structure of the automobile airbag is composed of the following parts, the airbag reinforcement frame 1, the airbag door 2, and the airbag hinge 3, which are integrally injection-molded with thermoplastic polyolefin (TPO) material However, the cost of TPO material is high, and its high-temperature performance is not as good as that of metal. TPO injection molded hinges are likely to be broken at high temperatures. another such as figure 2 As shown, the airbag door 5 and the airbag reinforcement frame 4 are two independent parts, which are connected and fixed by means of screws, bolts 6 or blind rivets 7, etc. However, this connection method is inconvenient to install, and the airbag door 5 It is easy to separate and fall off from the airbag reinforcement frame 4 . Cont...
