Embodiment Construction
[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] refer to figure 1 It is a schematic diagram of the composition of a high-efficiency bulletproof helmet. A high-efficiency bulletproof helmet, including an inner shell 1, a flexible part 2, a thin plate 3,
[0021] The outer surface of the inner shell 1 is connected with a plurality of flexible components 2, and the flexible components 2 are connected with thin plates 3, and the thin plates 3 are arc-shaped curved surfaces.
[0022] Further: the inner shell 1 is made of Kevlar fiber-reinforced composite material, wrapping the entire head of the combatant;
[0023] Further: the thin plate 3 is made of high-strength and lightweight 3K carbon fiber material, with a thickness of 20mm, refer to image 3 Its surface shape is desig...

The invention provides an efficient bullet-proof helmet. The problem that existing helmets are insufficient in bullet-proof property is solved. The efficient bullet-proof helmet comprises an inner shell, flexible parts and thin plates. The inner shell is connected with the multiple flexible parts through an adhesive, and the flexible parts are fixedly connected to the outer surface of the inner shell; and the flexile parts are connected with the thin plates through the adhesive. The flexible parts are compressed and deformed after being extruded by bullets, and then the thin plates move, so that direct penetration of the bullets is changed to oblique penetration and movement of the thin plates absorbs part of kinetic energy of the bullets. According to the efficient bullet-proof helmet, the bullets are made to slip off by designing the circular-arc-shaped thin plates; by designing the compressible flexible parts and the movable thin plates, the bullets are made to perform off-course oblique penetration; and part of kinetic energy of the bullets is absorbed through movement of the thin plates and the compression and deformation of the flexible parts, so that the penetration capacity of the bullets is weakened and the bullet-proof effect of the helmet is substantially improved.
Description
technical field [0001] The invention relates to a helmet, in particular to a high-efficiency bulletproof helmet. Background technique [0002] The helmet is a kind of personal protective equipment used to protect the head from injury. Statistics show that head injuries to combatants caused by fragments and direct projectiles are the main cause of combat attrition, much higher than the probability of death due to injuries to other parts of the body. Therefore, bulletproof helmets are the most basic and important protective equipment for combat personnel. [0003] The V50 value of existing military helmets is 630m / s, and the bullet resistance can basically meet the protection requirements of individual soldiers on the battlefield. However, in a complex battlefield environment, short-range fragments and direct projectiles can cause fatal damage to the combat personnel's head, and the short-range bulletproof performance of military helmets needs to be further improved. Theref...
