The high-speed impact cylinder 1 is provided with a piston rod 6 in a vertically sliding manner, the lower end of the piston rod 6 is connected with a hammer 4, and the hammer 4 is used for impacting a test piece (an air bag restraint system shell) placed on a test piece mounting bracket 15.
The air cannon energy storage assembly 2 is connected to the high-speed impact cylinder 1 and used for releasing high-pressure gas into the high-speed impact cylinder 1, so that the piston rod 6 is pushed to move downwards. The air pressure in the air cannon energy storage assembly 2 is at an adjustable setting.
The governor assembly 3 includes an inflatable air bag 7 and a brake ring 11. The stopper ring 11 is provided on the outer periphery of the inflatable airbag 7 so as to restrict the inflatable airbag 7 from expanding outward. The inflatable air bag 7 is tightly pressed on the periphery of the piston rod 6, thereby applying resistance to the piston rod 6. The inflation pressure of the inflatable air bag 7 is adjustable, so that the resistance can be adjusted. In another embodiment, the magnitude of the resistance to the piston rod 6 may be adjusted by simply expanding the inflatable air bag 7 without providing the brake ring 11.
The final impact speed of the hammer 4 is adjusted by adjusting the air pressure in the air cannon energy storage assembly 2 and the inflation pressure of the inflation air bag 7.
The hammer head 4 is detachably connected to the lower end of the piston rod 6 through a unhooking assembly 5. The unhooking assembly 5 comprises a lifting hook 8, a receiving portion 9 and a toggle 10.
As can be seen from fig. 2, the lower end of the piston rod 6 is inserted into the hammer head 4, so that a certain securing of the hammer head 4 is achieved, but the hammer head 4 still has a freedom of movement in the up-down direction with respect to the piston rod 6.
The lower end of the piston rod 6 is provided with a lifting hook 8, and the lifting hook 8 and the lower end of the piston rod 6 are arranged in a rotating mode.
The hammer 4 is provided with a receiving part 9, the receiving part 9 is a rod protruding out of the surface of the hammer 4, and the hook 8 is combined with the receiving part 9, so that the freedom degree of the hammer 4 relative to the piston rod 6 in the up-and-down direction is limited. In other embodiments, the receiving portion 9 may also be a receptacle provided on the surface of the hammer head 4, into which the hook 8 is engaged by being inserted.
The stirring piece 10 is arranged at the lower end of the stroke of the piston rod 6, when the piston rod 6 drives the hammer 4 to descend to the lowest point, the stirring piece 10 stirs the lifting hook 8 to enable the lifting hook 8 to rotate to be separated from the receiving part 9, the piston rod 6 stops, and the hammer 4 continuously moves downwards due to the inertia effect to impact a test piece.
In other embodiments, the hook 8 may be provided at the hammer head 4 and the receiving portion 9 may be provided at the lower end of the piston rod 6.
In other embodiments, the hammer head 4 may be inserted into the lower end of the piston rod 6.

Alternatively, two guide rods 14 are provided, the two guide rods 14 are parallel to each other and are spaced apart from each other, and two side portions of the hammer head 4 are slidably disposed on the guide rods 14, so that the hammer head 4 is guided more stably.
As shown in fig. 1, a hammer head resetting assembly 12 is further provided, and the hammer head resetting assembly 12 is used for lifting the hammer head 4 after the test is finished. Until the hammer head 4 is lifted to be in contact with the lower end of the piston rod 6, and the lifting hook 8 is pulled, so that the hammer head 4 is combined with the piston rod 6. The hammer head resetting assembly 12 may be a lifting tool such as a chain, a motor, etc. as is conventional in the art.
The lower end of the high-speed impact cylinder 1 is also provided with a reset air inlet 13. When the next impact test is carried out, air is introduced through the reset air inlet 13, the piston rod 6 returns to the highest position, the speed regulation assembly 3 is inflated to lock the piston rod 6, and the air cannon energy storage assembly 2 starts to store energy. And then, the speed regulation component 3 appropriately releases the locking piston rod 6, an air outlet valve of the air cannon energy storage component 2 is opened, high-pressure gas is released into the high-speed impact cylinder 1, and an impact test is carried out.
The equipment adopts high-pressure gas as power, so that the hammer head 4 obtains a great acceleration value, the impact speed required by the test can be reached in a short stroke, and the height of the impact equipment is greatly reduced compared with the original impact equipment.
