A device for detecting the stiffness of an automobile airbag

Abstract

The invention discloses an automobile airbag rigidity detection device. The automobile airbag rigidity detection device comprises an L-shaped operating platform (1), wherein two fixed blocks (2) are arranged on a vertical surface of the operating platform (1) in the vertical direction, the fixed blocks (2) comprise an upper fixed block (3) and a lower fixed block (4), the upper fixed block (3) is provided with a smooth through hole for a screw (5) to pass through, the upper surface of the lower fixed block (4) is provided with a circular groove for holding the bottom end of the screw (5), the screw (5) is connected with a movable block (6) in a threading manner, the movable block (6) is connected with an upper extrusion plate (8) in the horizontal direction through a vertical rod (7), and a surface, contacting the upper extrusion plate (8), of the vertical surface is provided with a square groove for preventing the left-right displacement of the upper extrusion plate (8). The automobile airbag rigidity detection device is high in automation degree, real and reliable in detection result, high in universality and applicable to the detection of various airbags in a car.

Description

technical field [0001] The invention relates to a device for detecting the stiffness of an automobile safety airbag, which belongs to the technical field of automobile parts detection. Background technique [0002] As an auxiliary configuration for the passive safety of the vehicle body, the airbag has been paid more and more attention by people. When the car collides with an obstacle, it is called a primary collision, and when the occupant collides with the internal components of the vehicle, it is called a secondary collision. When moving, it "flutters on the air cushion" to ease the impact on the occupant and absorb the collision energy, reducing the degree of injury of the occupant. [0003] Car airbags also have their unsafe side. According to calculations, if the car is traveling at a speed of 60km / h, a sudden impact will stop the vehicle within 0.2 seconds, and the airbag will pop out at a speed of about 300km / h, and the resulting impact force will be about 180kg. ...

AI Technical Summary

Problems solved by technology

[0004] The airbags are distributed in the front of the car (the front and rear seats), the sides (the front and rear rows in the car) and the roof. However, the existing car airbag stiffness detection devices can only detect airbags at fixed positions. Stiffness tests cannot be performed on all airbags in the vehicle

In addition, the existing automobile airbag stiffness detection device has a low degree of automation, requires human operation, is highly subjective, has large human errors, and has low detection accuracy and poor reliability.
