Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bulletproof helmets, in particular to a bulletproof helmet. Background Art
[0002] Bulletproof helmets are often used to prevent the head from being injured by bullets or shrapnel. Therefore, the outer shell of the bulletproof helmet is very hard, and straps are often used to wear the bulletproof helmet on the head.
[0003] The existing bulletproof helmets have the problem that when the bulletproof helmet is impacted, the vibration generated by the impact force inside the helmet is not easy to disperse;
[0004] The reason for this problem is that when using a bulletproof helmet, the bulletproof helmet needs to be worn on the user's head, and then the position of the helmet is fixed with a strap. The bulletproof helmet is designed to prevent the head from being damaged by bullets or shrapnel. The impact of the bullet is strong, so the impact force generated when the bullet hits the human head is relatively large, which causes certain vibration damage to the human head. The traditional shock absorption method is to set a shock-absorbing plate inside the helmet. This device is in close contact with the inside of the helmet, and the shrapnel impacts in an instant. At this time, the shock-absorbing plate that is closely fitted to the inside of the helmet will only reduce the impact force brought by the impact point, and after receiving the impact force, the inside of the bulletproof helmet will also vibrate, which cannot quickly disperse the vibration force caused by the impact. Therefore, we propose a bulletproof helmet. Utility Model Content
