Anti-shock automobile safety airbag stiffness test device

Abstract

The invention discloses an anti-shock automobile safety airbag stiffness test device comprising an L-shaped operation platform (1). Two fixing blocks (2) are arranged up and down on the vertical side of the operation platform (1), and the fixing blocks (2) include an upper fixing block (3) and a lower fixing block (4). The upper fixing block (3) is provided with a smooth through hole for a screw (5) to pass through. The upper surface of the lower fixing block (4) is provided with a circular groove. The screw (5) is in threaded connection with a moving block (6), and the moving block (6) is connected with an upper extruding board (8) in the horizontal direction. The top end of the vertical side is connected with a top board (15). A telescopic rod (16) is vertically arranged on the lower surface of the top board (15). The upper surface of the upper extruding board (8) is provided with a groove (17). According to the anti-shock automobile safety airbag stiffness test device provided by the invention, the test result is real and reliable, and the upper extruding board has an anti-shock function.

Description

technical field [0001] The invention relates to a device for detecting the stiffness of an anti-impact 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 ab...

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
