The fixing component 3 is composed of a fixing groove 31, a mounting plate 32, a hydraulic pump 33, a telescopic rod 34, and a U-shaped clamping plate 35. A fixing groove 31 is opened on the side of the first fixing plate 22. Two mounting plates 32 are symmetrically welded to both sides inside the fixing groove 31. Hydraulic pumps 33 are symmetrically provided on the sides of the two mounting plates 32. Telescopic rods 34 are symmetrically provided on the other sides of the two mounting plates 32. A driving component 8 is provided on the other top side of the base 1. The driving component 8 is composed of a second fixing plate 81, a lead screw 82, and a motor 83. Four lead screws 82 are arranged in a rectangle at a position corresponding to the fixing groove 31 on the side of the first fixing plate 22. A second fixing plate 81 is welded to the other top side of the base 1. An impact component 9 is provided above the base 1 at a position corresponding to the driving component 8. The impact component 9 is composed of a driving plate 91, a welding plate 92, an extension block 93, and an impact plate 94. A driving plate 91 is provided above the base 1 at a position corresponding to the lead screw 82.

[0024] Please refer to Figure 1-4 , in this embodiment, a number of support plates 23 are symmetrically welded to the side of the support block 21 at equal intervals. The side of the support plate 23 is welded to the other side of the first fixing plate 22. Start the motor 83. The motor 83 drives the lead screw 82 to rotate slowly forward or backward. The lead screw 82 rotating slowly forward or backward drives the impact component 9 to move left or right. Stop the motor 83 according to the indication of the scale line 10, completing the work of adjusting the position of the impact plate 94 according to airbag assemblies of different sizes.

[0025] Please refer to Figure 1-4 , four motors 83 are arranged in a rectangle at a position corresponding to the lead screw 82 on the side of the second fixing plate 81. One end of the lead screw 82 passes through the driving plate 91 and the second fixing plate 81 and is connected to the output end of the motor 83. A scale line 10 is provided on the top of the base 1 at a position corresponding to the impact plate 94. Start the motor 83. The motor 83 drives the lead screw 82 to rotate slowly forward or backward. The lead screw 82 rotating slowly forward or backward drives the impact component 9 to move left or right.

[0026] When working, the motor 83 is started according to the size of the airbag to be inspected. The motor 83 drives the lead screw 82 to rotate slowly forward or backward. The lead screw 82 rotating slowly forward or backward drives the impact assembly 9 to move left or right. The motor 83 is stopped according to the indication of the scale line 10. After the position of the impact plate 94 is adjusted, the operator opens the replacement door 6 and places the airbag assembly inside the fixing groove 31. At this time, the two hydraulic pumps 33 are started. The hydraulic pumps 33 drive the two U-shaped clamping plates 35 through the telescopic rods 34 to clamp the airbag assembly, thereby fixing the airbag assembly. After the airbag assembly is fixed, the motor 83 is started. The motor 83 drives the lead screw 82 to rotate rapidly forward. The lead screw 82 rotating rapidly forward drives the impact assembly 9 to move rapidly towards the airbag assembly in the fixing groove 31 until the impact plate 94 collides with the airbag assembly. The airbag assembly explodes after the collision, and the airbag fragments generated by the explosion are blocked by the protective plate 4 and the transparent top plate 7 to prevent the airbag fragments from hitting the personnel. When the impact plate 94 is damaged, the operator can open the maintenance door 5 to replace the impact plate 94, realizing the function of adjusting the position of the impact plate 94 according to airbag assemblies of different sizes.

[0027] Through the above steps, by setting a structure that can adjust the impact distance according to airbags of different sizes, impact inspection can be performed on airbag assemblies of all sizes, so as to solve the problem of a common vehicle airbag impact inspection device, which only includes an impact detection structure and can detect the impact of airbags, but lacks a structure that can adjust the impact distance according to airbags of different sizes, and cannot ensure that airbags of all sizes can be subjected to impact inspection, affecting the adaptability.
