Embodiment 2

[0023] In embodiment 2, when the airbag 5 is inflated and expanded, the airbag 5 is positioned at the bottom of the airbag frame 1, and the airbag 5 first touches the horizontal bar of the L-shaped lever A3 at close range when the airbag 5 expands. The angle is 80 degrees. During the extrusion process, the overall rotation is 10 degrees, so that the end 6 of the lever A3 slides to the right. Since the inclination of the groove 11 gradually becomes shallower from the side to the central engraved line of the upper end cover, the end Part 6 slides to the right to jack up the upper end cover, the central engraved line is opened, and the engraved line of the car dashboard also has a preliminary opening tendency.

Embodiment 3

[0024] In Embodiment 3, when the airbag 5 is inflated and inflated, the airbag 5 is located at the bottom of the airbag frame 1. When the airbag 5 inflates, it first touches the inclined lever B31 at a close distance, so that the lever B31 is inclined by force after being stressed. It becomes horizontal, and the horizontal distance becomes longer. Apply force to the side of the lever A3 with the notch, so that the end 6 of the lever A3 slides to the right. Due to the inclination of the groove 11, the center line of the upper end cover is drawn from the side gradually become shallower, so the end 6 slides to the right to jack up the upper end cover, the central engraved line is opened, and the engraved line of the car dashboard also has a preliminary opening tendency.

Abstract

The invention provides a high-safety car airbag in acceleration popping, comprising an airbag frame, wherein the end of the airbag frame is fixedly connected with a car instrument disk by friction welding; a safety airbag is set in an airbag frame; the two sides of the airbag frame are provided with jacking mechanisms; each jacking mechanism comprises a lever A which is hinged in the safety frame; the end of the lever A is set in an inclined shape; the surface is subjected to polishing treatment; an inclined groove matching with the end is set in the upper end cover of the airbag frame; and the inclination of the groove is gradually shallow from the side to the upper end cover. The car airbag has following effects: during the expansion process of the airbag, the lever A is pressed; the lever A rotates a certain angle to jack the upper end face of the airbag frame; on the one hand, the popping speed of the airbag is quickened to prevent blocking the airbag; on the other hand, the groove at the upper end cover is jacked with the instrument disk after being thinned, and the probability knocking out the chippings is greatly reduced.

Description

technical field [0001] The invention belongs to the field of safety airbag equipment, and in particular relates to a high-safety accelerated ejection automobile safety airbag. Background technique [0002] An airbag is installed on the inner side of the dashboard in front of the passenger seat to protect the seated passengers. The airbag device of the car can prevent or reduce casualties in the event of a car collision, because in an emergency collision, the airbag frame needs to be able to open urgently, but there are The airbag frame is easily damaged and the airbag cannot be deployed normally, which affects the protective effect. In the past, the airbag fixed frame adopts a single side opening structure, and the inflation and expansion speed is slow, which is dangerous to the human body. Well, resulting in a situation where it gets stuck or only a small portion of the airbag comes out when opened. [0003] Although the current safety airbag frame has been improved, the o...
