Anti-impact car airbag stiffness testing device

Abstract

The invention discloses an impact-proof automobile air bag rigidity detection device. The impact-proof automobile air bag rigidity detection device comprises an L-shaped operation bench (1). Two fixed blocks are arranged on a vertical surface of the operation bench (1) in an up-down manner. The fixed blocks include an upper fixed block (3) and a lower fixed block (4). A smooth through hole penetrating a screw (5) is formed in the upper fixed block (3). A circular groove for accommodating the bottom end of the screw (5) is formed in the upper surface of the lower fixed block (4). The screw (5) is in threaded connection with a movable block (6). The movable block (6) is connected with a horizontal upper extruding plate (8) through an upright column (7). A plurality of grooves (15) for accommodating heavy objects are formed in the upper surface of the upper extruding plate (8). The impact-proof automobile air bag rigidity detection device provided by the invention is high in automatic degree and is real and reliable in detection result, the upper extruding plat has an impact-proof function, and the universality is high.

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...

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.

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
