when the stress pad A301 is in a stretching state, the eight air doors A203 in the air sleeve A2 are in an opening state, so that an external air source enters the helmet 1 to provide ventilation effect for the interior of the helmet 1, and on the other hand, the auditory perception of outside is prevented from being reduced when a person wears the helmet 1;

when the stress pad A301 is collided, the stress pad A301 moves rightwards, the transmission wheel A204 is meshed with the rack of the stress pad A301 for transmission, so that the transmission wheel A204 rotates, when the driving wheel A204 rotates, the uppermost driving rod A202 in the windband A2 is driven to rotate, when one transmission rod a202 rotates, the gear ring a201 is driven to rotate, a state in which the eight transmission rods a202 are rotated synchronously to close the eight dampers a203, the middle position of the wind sleeve A2 is sealed, so that when the left side of the helmet piece 1 is impacted, an external medium enters the helmet piece 1 through the middle position of the wind sleeve A2 to hurt a wearer, and when the stress pad A301 moves rightwards to drive the single transmission rod A202 to rotate, resistance exists when the single transmission rod A202 drives the toothed ring A201 to rotate, and then the effect of reducing the amplitude of an acting force on the stress pad A301 can be achieved;

when the right position of the helmet is impacted by external force, the whole stressed pad B501 slides leftwards in the connecting piece B5, when the stressed pad B501 slides, the two limit gears B502 rotate synchronously, when the two limit gears B502 rotate, the two thrust reversers B503 are driven to slide in the connecting piece B5 and in the positions opposite to the stressed pad B501, the stressed pad B501 is subjected to leftward acting force and is transmitted to the right position, when the two thrust reversers B503 move rightwards, because the middle position of each fork frame B504 is provided with a telescopic rod, and the telescopic rod body is provided with a spring, and the right position of the fork frame B504 is respectively and fixedly connected with the two circular supporting rods of the connecting piece B5, when the fork frame B504 is subjected to the acting force of the thrust reversers B503, the fork frame B504 is pressurized, so that the telescopic rod in the middle of the fork frame B504 contracts, and partial force buffering is performed through the telescopic rod springs of the fork frame B504, when the thrust reverser B503 drives the fork frame B504 to continue extruding, the front end and the rear end of the fork frame B504 are jointed with the inner part of the connecting piece B5 and the end surface of the partition plate of the connecting piece B5, so that the acting force borne by the stress pad B501 is completely transmitted to the connecting piece B5, the acting force in the left-right direction is converted into the acting force in the front-back direction, and the direction of the acting force is changed to carry out dispersion treatment;

when the stress pad B501 is in the stretching state, the eight air doors B403 in the air sleeve B4 are in the opening state, so that an external air source enters the helmet 1 to provide ventilation effect for the interior of the helmet 1, and on the other hand, the auditory perception of outside is prevented from being reduced when a person wears the helmet 1; when the stress pad B501 is collided, the stress pad B501 moves leftwards, the transmission wheel B404 is meshed with the rack of the stress pad B501 for transmission, so that the transmission wheel B404 rotates, when the transmission wheel B404 rotates, the transmission wheel B402 at the uppermost end in the windband B4 is driven to rotate, when one driving rod B402 rotates, it will drive the toothed ring B401 to rotate, causing the eight drive rods B402 to rotate in synchronism, causing the eight dampers B403 to close, seal the wind sleeve B4 intermediate position, when avoiding helmet 1 right side to receive the striking, the injury to wearing personnel is caused in the external medium enters into helmet 1 through wind sleeve B4 intermediate position, and on the other hand when atress pad B501 moves left and drives single transfer line B402 and rotate, there is the resistance when single transfer line B402 drives ring gear B401 and rotates, and then can play the effect of reducing the width of cloth to the effort that atress pad B501 received.
