[0047] In this embodiment, the support head mold 504 supports the helmet with the cooperation of the mounting seat 501, the locking bolt 502 and the fixed support rod 503, the chin strap of a group of helmets is hung with the chin strap clamping rod 305, the impact weight 303, the light bar 301 and the load-bearing plate 302 are straightened under the action of their own gravity, and the staff starts the cooling plate 606, the No. 1 exhaust fan 609 and the No. 2 exhaust fan 610 through the control box 102, the heating end of the cooling plate 606 heats the air in the hot chamber, and the No. 1 exhaust fan 609 inputs the hot air from the hot chamber into the No. 1 box 601 through the No. 1 air inlet pipe 607, thereby adjusting the temperature inside the No. 1 box 601. At the same time, the cooling end of the refrigeration plate 606 cools the air in the cold chamber. At the same time, the No. 2 exhaust fan 610 inputs the cold air from the cold chamber into the No. 2 box 602 through the No. 2 air inlet pipe 608, thereby adjusting the temperature inside the No. 2 box 602. The staff starts the servo motor 403 through the control box 102, so that the servo motor 403 drives the lead screw 404 to rotate, further The lead screw 404 drives the first lifting plate 405 to descend with the cooperation of the square column 203, and further causes the two sets of second lifting plates 406 to drive the electromagnet 407 to descend. When the two sets of electromagnets 407 are in contact with the top of a set of impact weights 303 respectively, the control box 102 is operated to energize the two sets of electromagnets 407 to generate magnetism, so that the electromagnet 407 magnetically absorbs the impact weights 303, and then the servo motor 403 is operated to rotate in the opposite direction, so that the lead screw 404 drives the first lifting plate 405 to rise, and further causes the electromagnet 407 to move upward. The iron 407 drives the impact weight 303 to rise. When the impact weight 303 rises to the detection height, the staff cuts off the power of the electromagnet 407 through the control box 102, so that the electromagnet 407 releases the magnetic adsorption of the impact weight 303, and the impact weight 303 extends the vertical direction of the optical bar 301 to perform free fall movement. When the impact weight 303 is released from the corresponding load-bearing plate 302, the optical bar 301 and the L-shaped lifting block 304 drive the chin strap clamping rod 305 to pull the rope, thereby performing a tensile strength test.

[0048] The present invention is a comprehensive strength tester for helmet wearing system. According to different specific test scenarios and different standard requirements, the wearing device also needs to be tested for static strength and dynamic strength to ensure that the helmet can be firmly worn on the head in different scenarios. In some special scenarios, if the wearing device cannot firmly fix the helmet on the head, the helmet will fall off the head, the helmet will lose its due protective effect, and cause head injury. The static strength of the wearing device continuously applies static tension to the wearing device to see the maximum force value when the wearing device fails. The failure includes chin strap breakage, The equipment consists of a head mold, an artificial chin, a chin support, a force loading device, a sensor and a data acquisition device. During the experiment, the helmet is worn on the head mold, and then the chin strap is fastened to the artificial chin. Then the force loading device drives the chin support to move downward at a speed of 150N / min. The downward movement of the chin support drives the chin strap to be gradually tightened. After reaching 150N, the speed is reduced to 20N / min and the loading is continued until the entire wearing device including the chin strap fails. At this time, the maximum value is recorded, and the maximum value is the static strength value. The control box 102, touch display screen 103, impact weight 303, servo motor 403, electromagnet 407, cooling plate 606, exhaust fan No. 1 609 and exhaust fan No. 2 610 of the helmet wearing system comprehensive strength tester of the present invention are purchased on the market, and technical personnel in the industry only need to install and operate them according to the accompanying instruction manual without the need for technical personnel in this field to make creative labor. The static strength detection part 701 is the company's original product module, and the module is directly integrated in this solution.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
