[0033] Embodiment 2

[0034] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the second embodiment of the utility model, the damping mechanism 3 includes the memory sponge 305 of fixedly connected to the inner wall of helmet inner shell 1, the outer surface of memory sponge 305 is fixedly connected with fixed ring 308, the upper surface of fixed ring 308 is fixedly connected with spring 306 and multiple dampers 307, and the upper end of spring 306 is fixedly connected to the inner wall of helmet inner shell 1.

[0035] Specifically, the lower surface of fixed ring 308 is fixedly connected with positioning sponge 309, and the lower surface of positioning sponge 309 is provided with groove, the outer surface of helmet inner shell 1 is fixedly connected with vent pipe 304, the upper end of vent pipe 304 is fixedly connected with fixed frame 303 through the outer surface of flow guide layer 201, the outer surface of helmet inner shell 1 is fixedly connected with restraint belt 310, the outer surface of restraint belt 310 is fixedly connected with fixed sleeve 302, and the outer surface of fixed sleeve 302 is threadedly connected with fastening knob 301.

[0036] Further memory sponge 305 and positioning sponge 309 are used, not only to provide comfortable support for the head, but also to accurately position the top of the head, making the helmet fit more closely and stably. At the same time, the shock-absorbing mechanism 3 composed of springs 306 and dampers 307 can quickly absorb and dissipate energy when impacted, reducing the damage of impact force to the head.

[0037] Working principle: The first ceramic layer 202 and the second ceramic layer 203 are arranged in a staggered manner, which is the key design to improve the bulletproof ability of the helmet. The traditional single-layer ceramic sheet often has the problem of weakened bulletproof ability at the joint, and when a bullet or other high-speed impact object hits the joint, it is easy to break through the protection. While the first ceramic layer 202 and the second ceramic layer 203 are staggered, this defect is effectively compensated for. When external impact objects attack, the first ceramic layer 202 first withstands the impact, and the high-hardness ceramic material can preliminarily block and break the impact object, dispersing its energy. If the impact object has a large energy that penetrates the first ceramic layer 202, the second ceramic layer 203 will then play a role, further blocking and absorbing the remaining energy, and the two ceramic layers cooperate with each other, greatly enhancing the overall bulletproof effect of the helmet. Moreover, the first positioning block 204 and the second positioning block 205 provide precise positioning for the installation of the ceramic layer. The first positioning block 204 cooperates with the positioning groove on the outer surface of the inner shell 1 of the helmet, accurately pasting the second ceramic layer 203 in the right position; the second positioning block 205 cooperates with the limiting groove on the outer surface of the second ceramic layer 203, so that the first ceramic layer 202 can be accurately arranged in a staggered manner with the second ceramic layer 203, ensuring the stability and effectiveness of the entire bulletproof structure.

[0038] The shock-absorbing mechanism 3 in the helmet plays an important role in wearing comfort and shock-absorbing protection. The memory sponge 305 is attached to the inner wall of the helmet inner shell 1, which has good flexibility and adhesion, and can adaptively deform according to the shape of the wearer's head to provide comfortable support for the head. At the same time, the positioning sponge 309 is fixed to the lower surface of the fixed ring 308, and the recesses opened on the lower surface can accurately fit the top of the wearer's head, play a positioning role, and make the helmet wear more stable. When the flow guide layer 201 of the helmet is hit, the impact force will be transmitted to the helmet inner shell 1, and then act on the shock-absorbing mechanism 3. At this time, the spring 306 will deform, and the elastic deformation of the spring 306 can absorb part of the impact energy. A plurality of dampers 307 play a key role in the process of spring 306 deformation, which can dissipate the energy generated by the deformation of spring 306 in the form of heat energy, etc., to avoid the rebound of energy causing secondary damage to the head. Through the cooperative work of spring 306 and damper 307, the protection strength of the top of the head is effectively increased, and the damage of the impact to the wearer's head is reduced. The air pipe 304 is fixed on the outer surface of the helmet inner shell 1, and its upper end penetrates the flow guide layer 201 and is connected with the fixed frame 303. During wearing, the air pipe 304 can exhaust the hot air and moisture generated by the human head in the helmet inner shell 1, and form convection with the fresh air outside, increase the air circulation in the helmet inner shell 1, and keep the head dry and comfortable.
