Device for detecting rigidity of automobile safety airbag

Abstract

The invention discloses a device for detecting rigidity of an automobile safety airbag. The device comprises an L-shaped operation platform (1), wherein two fixing blocks (2) are upward and downward arranged on the vertical surface of the L-shaped operation platform (1); a vertical slide rail (15) is arranged between the two fixing blocks (2); each of the fixing blocks (2) comprises an upper fixing block (3) and a lower fixing block (4); a smooth through hole penetrating through a screw rod (5) is formed on the upper fixing block (3); a circuit groove used for loading the bottom end of the screw rod (5) is formed on the upper surface of the lower fixing block (4); a moveable block (6) is in threaded connection with the screw rod (5); the moveable block (6) can slide on the vertical slide rail (15); the moveable block (6) is connected with a horizontal upper extruding plate (8) through a vertical rod (7). The device for detecting the rigidity of the automobile safety airbag provided by the invention has the advantages of high degree of automation, true and reliable detection result, strong universality and applicability to the detection for various airbags in the automobile.

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 side (the front row and the rear row) and the roof of the car. However, the existing car airbag stiffness detection devices can only detect airbags at fixed positions. It is not possible to test the stiffness of all the airbags in the car

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.

In addition, the current automobile airbag stiffness detection device has poor anti-shock effect, and the extrusion plate that should be fixed in the impact test is prone to displacement, resulting in a small value measured by the pressure sensor, unreliable measurement results, and easy misleading. Airbags are a safety hazard
