Through the linkage structure of the connecting block 23, the closing handle 22, and the release device body 19, the opening and closing plate 20 is rotated, and the hook lock hole is opened, thereby realizing the release of the simulated person, allowing the simulated person to fall freely and generate an impact force on the safety belt fixed to the suspension cone.

[0028] Working principle:

[0029] In this invention, the suspension cone 2 is used to secure the safety belt, and the release device is used to secure the mannequin. The operation of the lift 18 allows the release device to move downwards to near the ground. Pulling down the release handle 21 opens the hook lock hole, allowing the testing personnel to secure the mannequin to the release device on the ground. The handle 22 is then closed, closing the hook lock hole. Pulling the release rope 9 causes the sliding plate 6 to slide backwards, disengaging it from the locking ring groove 15. This allows the cone slider 13 and the mannequin to fall freely under gravity, bringing the suspension cone down to near the ground so the testing personnel can secure the safety belt to it. Finally, the lift 18 pulls the mannequin upwards. Move the device to the specified detection height and keep it suspended. Then pull the lifting rope 17 to move the suspended cone 2, which is fixed with a safety belt, upward. During the pulling process, the truncated cone of the cone slider 13 abuts against the front end of the sliding plate 6. Through the pressure of the truncated cone, the suspended cone 2 can pass through the suspension through hole until the sliding plate 6 is directly opposite the locking ring groove 15. Under the action of the return spring 7, it quickly returns to its original position and extends into the locking ring groove 15, forming a locking and positioning of the suspended cone 2 in the vertical direction. At this time, the safety belt is in a free bending state. The above operation can fix the mannequin and the safety belt on the mannequin at the detection height without the need for the detection personnel to climb up to install and fix it, thus avoiding safety hazards.

[0030] When testing is required, pull the release rope 24 at the end of the release handle 21, and the opening and closing plate 20 opens, allowing the mannequin to release instantly and fall freely from the release device. When it falls to the taut state of the seat belt, the impact force generated by the mannequin acts on the seat belt and is transmitted to the pressure sensor 4 through the suspension cone 2, release seat 5, mounting guide rod 11, and connecting guide plate 12. The pressure sensor 4 can detect the dynamic impact force of the mannequin.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
