It is worth noting that: the detection box 300 cannot completely realize weightlessness due to the existence of air resistance in the falling process, so that the weightlessness component 200 is required to apply a downward driving force to the detection box 300 in the weightlessness falling process, so as to counteract the interference of the air resistance, and further enable the detection box 300 to be in a completely weightless state (the judgment is based on the motion sensor 903 on the detection box 300).
(III)

The purpose of the backup assembly 500 is to protect the detection box 300 from a deceleration process that is close to the ground, thereby avoiding the risk of the detection box 300 directly falling when the weightless assembly 200 fails.
(IV)
The ground at the bottom end of the vertical guide rail 201 is also provided with a group of buffer assemblies 600 which are positioned right below the detection box 300, each buffer assembly 600 comprises a telescopic rod 601, a spring 602 and an electromagnet 603, the two ends of each telescopic rod 601 are respectively provided with the electromagnets 603 with magnetic axes parallel to the central axis of the corresponding telescopic rod, the springs 602 are sleeved outside the telescopic rods 601, and the inside of each telescopic rod 601 is filled with magnetic fluid solution.
The cushioning assembly 600 functions to slow down the test box 300 as it approaches the ground, thereby avoiding the risk of the test box 300 falling directly when both the weightless assembly 200 and the backup assembly 500 are malfunctioning.
In addition, the control cabinet 100 can also adjust the magnetic field intensity of the electromagnet 603 according to the falling speed of the detection box 300 (the judgment basis is from the motion sensor 903 and the second distance sensor 905 on the detection box 300), so as to change the viscosity of the magnetic fluid solution, so that the buffer assembly 600 is in the designated damping coefficient, and thus, the better buffer protection of the detection box 300 is realized.
(V)

It is worth noting that: the control cabinet 100 commands the pressure sensor 901 to sense the normal force of the linear motor during the full weight loss fall of the detection box 300.
It is worth noting that: the working states of the four lead screw sliders 404 on the same mounting plate 402 are always synchronous, and the mounting plate 402 is always in a state of being parallel to the ground.
It is worth noting that: a rigid air gap adjustment pad 410 is further disposed between the stepped clamping plate 407 and the secondary 800 of the linear motor, so that a user can adjust the width of the air gap between the primary 700 of the linear motor and the secondary 800 of the linear motor by using air gap adjustment pads 410 with different thicknesses. And a rigid supporting cushion body 411 is arranged between the two corresponding fin plates 408, so that the two fin plates 408 at the same horizontal end can be always kept in a state of being parallel to the ground.
