Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, specifically to a novel multifunctional protective helmet and helmet. Background Technology

[0002] Bulletproof helmets are protective gear designed to safeguard the human head. Traditional bulletproof helmets are mostly made of a single material (such as aramid or metal), resulting in problems such as heavy weight, low energy absorption efficiency, and insufficient resistance to deformation. Upon impact from high-speed fragments or stray bullets, they are prone to penetration or deformation injuries due to localized stress concentration. Furthermore, existing helmets have poor adaptability to special environments such as those requiring protection against nuclear radiation, corrosion, or toxic substances. Given the current tense international situation, improving the performance of bulletproof helmets and enhancing soldier comfort is of paramount importance. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a novel multifunctional protective helmet shell and helmet, which adopts a composite woven structure with "deceleration-energy absorption-deformation resistance" functional zones. Through the synergistic optimization of materials and weaving processes, it achieves a balance between lightweight and high protective performance.

[0004] A novel multifunctional protective helmet shell includes a helmet shell body, which, from the inside out, comprises a three-dimensional woven UHMWPE fiber layer, a three-dimensional braided UHMWPE fiber layer, and a three-dimensional braided carbon fiber layer.

[0005] As a preferred and feasible approach, a three-dimensional woven UHMWPE fiber layer is used as an anti-deformation layer, with a density of 1.0~1.2 g / cm³. 3 Weight is 130~180g / m 2 Therefore, this structure limits the lateral spread of the shock wave through its tightly woven structure, reducing the amount of deformation on the back side.

[0006] As a preferred feasible method, a three-dimensional woven UHMWPE fiber layer is used as the energy-absorbing layer, with a density of 0.97~1.0 g / cm³. 3 The weight is 150~260g / m³ 2 Therefore, this structure absorbs the kinetic energy of the spring sheet through fiber plastic deformation, reducing the risk of fiber breakage.

[0007] As a preferred feasible method, a three-dimensional braided carbon fiber layer with a density of 1.5~1.8 g / cm³ is used as a deceleration layer. 3 Weight is 150~200g / m 2 Therefore, the high modulus properties of carbon fiber are used to rigidly resist the penetration of shrapnel and disperse impact stress.

[0008] As a preferred feasible approach, a radiation-shielding coating is placed between the three-dimensional woven UHMWPE fiber layer and the three-dimensional braided UHMWPE fiber layer, and a polyurea layer is coated on the outer surface of the three-dimensional braided carbon fiber layer. The radiation-shielding coating is a boronized polyethylene film with a thickness of 0.1-0.3 mm and a boron content of 5-15 wt%, which can be used to absorb neutron radiation; the polyurea layer has a thickness of 0.2-0.5 mm, which can improve wear resistance and chemical corrosion resistance.

[0009] This invention also provides a novel multi-functional protective helmet, employing the aforementioned helmet shell, with the lower end of the shell extending downwards to form a sealed protective section, and a filter device embedded therein. The filter device includes a HEPA filter element and an activated carbon layer, which can be replaced independently.

[0010] As a preferred option, the front of the helmet is equipped with a protective goggle for observation. The goggle is made of polycarbonate and coated with an anti-fog / anti-laser coating.

[0012] This utility model helmet has a novel and reasonable structure. It adopts a composite woven structure with functional zones of "deceleration-energy absorption-deformation resistance". Through the synergistic optimization of materials and weaving process, it has the properties of bulletproof, anti-toxic and anti-radiation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that all uses of "first", "second", "third" and "fourth" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first", "second", "third" and "fourth" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-2 As shown, this utility model discloses a novel multifunctional protective helmet shell, comprising a helmet shell body 6. From the inside out, the helmet shell comprises a three-dimensional woven UHMWPE fiber layer, a three-dimensional braided UHMWPE fiber layer, and a three-dimensional braided carbon fiber layer. A radiation-shielding coating is provided between the three-dimensional woven UHMWPE fiber layer and the three-dimensional braided UHMWPE fiber layer. The outer surface of the three-dimensional braided carbon fiber layer is coated with a polyurea layer. This not only improves the helmet's radiation protection capability but also its wear and corrosion resistance. The three-dimensional woven UHMWPE fiber layer serves as an anti-deformation layer, the three-dimensional braided UHMWPE fiber layer as an energy-absorbing layer, and the three-dimensional braided carbon fiber layer as a deceleration layer.

[0020] It should be noted that the three-dimensional woven UHMWPE fiber layer, serving as an anti-deformation layer, has a density of 1.0~1.2 g / cm³. 3 Weight is 130~180g / m 2 Therefore, this structure, through its tightly woven structure, restricts the lateral diffusion of the shock wave and reduces the amount of deformation on the back side. The three-dimensionally woven UHMWPE fiber layer serves as the energy-absorbing layer, with a density of 0.97~1.0 g / cm³. 3 The weight is 150~260g / m³ 2 Therefore, this structure absorbs the kinetic energy of the spring sheet through fiber plastic deformation, reducing the risk of fiber breakage. The three-dimensional woven carbon fiber layer acts as a deceleration layer, with a density of 1.5~1.8 g / cm³. 3 Weight is 150~200g / m 2 Therefore, the high modulus properties of carbon fiber are used to rigidly resist the penetration of shrapnel and disperse impact stress.

[0021] In addition, a radiation-shielding coating is placed between the three-dimensional woven UHMWPE fiber layer and the three-dimensional braided UHMWPE fiber layer, and a polyurea layer is coated on the outer surface of the three-dimensional braided carbon fiber layer. The radiation-shielding coating is a boronized polyethylene film with a thickness of 0.1-0.3 mm and a boron content of 5-15 wt%, which can be used to absorb neutron radiation; the polyurea layer has a thickness of 0.2-0.5 mm, which can improve wear resistance and chemical corrosion resistance.

[0022] This invention also provides a novel multi-functional protective helmet, employing the aforementioned helmet shell, with the lower end of the shell extending downwards to form a sealed protective section, and a filter device embedded therein. The filter device includes a HEPA filter element and an activated carbon layer, which can be replaced independently.

[0023] It should be noted that the sealed protective part is made of airtight rubber. In order to create a sealed space inside the helmet, the bottom part of the helmet that comes into contact with the human body needs to have good sealing performance. Therefore, the sealed protective part of this application uses sealing rubber. Rubber has sufficient elasticity and softness, which can conform well to the human body, thereby achieving a sealing effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
