Problems solved by technology

like Image 6 As shown, the metal hinge structure in the prior art generally only adopts a single hinge form, and the hinge structure 33' is a single-layer metal with a rectangular opening, and its strength is relatively weak. Release, so the hinge is generally designed to be longer
And when the metal airbag door system rotates open, under a certain speed and impact force, the metal hinge structure 33' will be completely straightened, so that the turning radius of the metal airbag door system is relatively large. Under certain circumstances, the fully opened metal airbag door system may collide with the front windshield of the car, causing the glass to break, thereby causing injury to the occupants

Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the present invention is further described, so that it can better understand the function and characteristics of this patent.

[0029] see Figures 1 to 3 , the metal airbag door system of this embodiment covers the airbag opening 10 of the airbag module 1 on the passenger side of the instrument panel, and includes the instrument panel cover 2 and the metal airbag door structure 3 .

[0030] The instrument panel cover 2 includes a skin 21 , a foam layer 22 and a skeleton 23 which are sequentially connected from top to bottom, and the instrument panel cover 2 is provided with a metal airbag door weakening line.

[0031] The metal airbag door structure 3 is used to turn over the metal airbag door structure 3 , and includes an airbag door body 31 and a hinge portion 32 connected to one side of the airbag door body 31 . Wherein, the airbag door body 31 is fixedly connected to the bottom surface of the frame 23 , and the hinge...

Abstract

The invention provides an air bag door structure which covers an opening of a supplementary restraint system module of the passenger side of an instrument board. A metal air bag door system comprises an air bag door body and a hinge portion connected onto one side of the air bag door body. A weakening structure for absorbing compression energy produced during expansion of an air bag is arranged on the air bag door body, and a strengthening structure for improving the hinge strength is arranged on the hinge portion. The metal air bag door structure has a small turnover radius, so that the metal air bag door system can be prevented from colliding with an automobile front windshield; moreover, the structure also has a small turnover angle and low turnover speed, so that even if the metal air bag door system collides with the automobile front windshield, impact force on the automobile front windshield can be reduced, and hurts to passengers caused by cracking of the front windshield are finally avoided.

Description

technical field [0001] The invention relates to an automobile instrument panel safety airbag door, in particular to a metal airbag door structure and system. Background technique [0002] For foamed instrument panels, the commonly used metal airbag door system includes two parts, the metal airbag door structure and the instrument panel cover, which are pre-connected to form a complete metal airbag door system. Among them, the weakening line provided on the instrument panel cover is usually U-shaped, and the metal airbag door structure is generally made of metal. [0003] The moment the airbag on the passenger side is triggered and opened, the metal airbag door system will quickly rotate and open under the pressure of the airbag bag. Therefore, the turning part of the metal airbag door system is generally designed as a metal hinge structure. Such as Image 6 As shown, the metal hinge structure in the prior art generally only adopts a single hinge form, and the hinge structu...
