Bulletproof helmet

Abstract

The invention relates to the technical field of bulletproof devices, and provides a bulletproof helmet, which comprises an outer shell and an inner shell; a bulletproof layer is arranged on the outer shell; a buffer layer is arranged on the inner shell; the buffer layer comprises a first buffer group making contact with the head top of a wearer and a second buffer group making contact with other parts, except the head top, of the wearer; each of the first buffer group and the second buffer group comprises a plurality of buffer gaskets; the plurality of buffer gaskets of the first buffer group are not connected; and every two adjacent buffer gaskets of the second buffer group are connected. By the adoption of the technical scheme, the first buffer group, the second buffer group and the arrangement mode of the first buffer group and the second buffer group jointly achieve comfort of the bulletproof helmet; and the bulletproof layer located on the outer side of the buffer layer achieves protection of the bulletproof helmet.

Description

technical field [0001] The invention relates to the technical field of bulletproof devices, in particular to a bulletproof helmet. Background technique [0002] Bulletproof helmet is a protective equipment that can absorb and dissipate bullet energy, prevent penetration and effectively protect the human head. The performance of bulletproof helmets includes bulletproof performance and protective performance. Among them, bulletproof performance refers to the anti-penetration performance of bulletproof helmets to bullets, and protective performance refers to the non-penetration resistance of bulletproof helmets to human heads when bullets do not penetrate bulletproof helmets. Injury (blunt injury) performance. [0003] According to different bulletproof materials, bulletproof helmets are divided into soft bulletproof helmets, hard bulletproof helmets and soft and hard composite bulletproof helmets. These bulletproof helmets can block the penetration of bullets and have excelle...

AI Technical Summary

Problems solved by technology

However, the penetrating energy of the bullet will be transmitted to the head of the human body along the bulletproof helmet in the form of stress waves, which will cause different degrees of blunt damage to the head of the human body.

Therefore, a buffer layer (such as EVA, EPE, PU and PC, etc.) is usually added to the bulletproof helmet to weaken the impact of the bullet on the human head, but these materials are less comfortable and the protective performance needs to be improved. Affects the comfort and protection of bulletproof helmets when worn
