[0026] The embodiments of the technical scheme of the present utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present utility model, thus only serve as examples, and cannot limit the protection scope of the present utility model.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meanings understood by the technical personnel in the field to which the present utility model belongs.

[0028] The embodiment of the present utility model provides a chain shell structure protective device, which comprises a sponge layer 100 and a hard protective layer 200 arranged outside the sponge layer 100.

[0029] The sponge layer 100 can be at least one of EVA, PU, NBR, SBR or latex, which is arranged on the side of the hard protective layer 200 close to the human body, used to improve the comfort of the wearer and provide shock absorption and buffering performance. Preferably, the sponge layer 100 selects one of RZ-PU composite material, RZ-EVA composite material, RZ-NBR composite material or RZ-XPE composite material. These sponge layers 100 can absorb more than 90% of the impact energy, reducing the probability of fracture.

[0030] The hardness of the hard protective layer 200 is greater than or equal to 25D, and the hard protective layer 200 can absorb most of the impact energy and provide reliable protection.

[0031] In the embodiment, referring to Figures 2-4 , the hard protective layer 200 comprises a plurality of pieces of shell 210 arranged flat and a plurality of connecting rings 220 for connecting the pieces of shell 210 to each other.

[0032] Optionally, the shape of the plate armor 210 can be a regular polygon or other irregular shape, and different shapes of plate armors can also exist in the same hard protective layer 200.

[0033] Optionally, the thickness of the hard protective layer 200 is 3-18mm, and the thicker the hard protective layer 200 is, the stronger its protective ability is. However, the hard protective layer 200 should not be too thick, because as the thickness increases, the mass of the hard protective layer 200 will also increase accordingly. Preferably, the thickness of the hard protective layer 200 is 4-12mm, and under this thickness, the hard protective layer 200 is relatively light and has good protective ability.

[0034] The hard protective layer 200 of the chain armor protective device in the embodiment has a relatively complex structure, but it can be printed by an FDM three-dimensional printer, and the structure shown in Figure 2 can be 3D printed without support, without the need to remove the support after printing is completed, saving manpower and preparation time, improving production efficiency while significantly reducing manufacturing cost, so the cost of the chain armor protective device in the present application is much lower than that of the existing custom protective device.

[0035] Optionally, the maximum gap between the two adjacent plate armors 210 should be 1-3.5mm. If the maximum gap is too small, the flexibility and air permeability of the hard protective layer 200 are poor, and it is difficult to separate the plate armors 210 and the connecting rings 220 after 3D printing is completed. If the maximum gap is too large, the reliability of the protection of the hard protective layer 200 will decrease.

[0036] Optionally, the material of the plate armor 210 is one of TPU, PETG or PA. These materials have high hardness and certain toughness, and can provide reliable protection performance. It should be noted that the TPU, PETG or PA referred to in the present application includes pure TPU, PETG or PA material, and also includes improved materials based on TPU, PETG or PA, such as PETG-CF (carbon fiber reinforced PETG), PETG-AF (glass fiber reinforced PETG), PA-CF (carbon fiber reinforced PA) or PA-AF (glass fiber reinforced PA) and the like.

[0037] Each plate armor 210 is surrounded by at least three connecting positions, and each connecting ring 220 passes through the connecting positions around it to connect the plate armors 210 around it, and a matching gap is provided between the connecting ring 220 and the connecting positions.

[0038] It can be understood that the provision of three or more connecting positions around the plate armor 210 can ensure that the plate armor 210 swings in different directions, thereby ensuring the flexibility of the hard protective layer 200 composed of the plate armors 210.

[0039] It can be understood that the number of the connecting ring 220 connected to the piece of leather 210 can be two, three, four or even more, Figure 4 In the embodiment shown, the number of the connecting ring 220 connected to the piece of leather 210 is four.

[0040] In some embodiments, the edge of the piece of leather 210 is provided with a convex edge 211 protruding inwardly, and each connecting position includes two limiting holes 212 provided on the convex edge 211 for the connecting ring 220 to pass through.

[0041] In this embodiment, the convex edge 211 is provided on the edge of the piece of leather 210, and the limiting hole 212 is provided on the convex edge 211 for the connection of the connecting ring 220. This not only meets the connection requirement of the connecting ring 220 and the piece of leather 210, but also reduces the material of the piece of leather 210 under the premise of ensuring the strength of the piece of leather 210, thereby reducing the cost and the weight of the entire protective equipment structure.

[0042] Optionally, the ratio of the height of the limiting hole 212 to the thickness of the connecting ring 220 is 1:(0.35-0.85). This size ratio mainly affects the degree of flexibility of the hard protective layer 200. When the thickness of the connecting ring 220 is too high, the flexibility is too poor, and when the thickness of the connecting ring 220 is too low, the strength is poor.

[0043] Optionally, the ratio of the width of the limiting hole 212 to the width of the connecting ring 220 is 1:(0.35-0.85). This size ratio affects the degree of flexibility and flexibility of the hard protective layer 200 to some extent, and also indirectly affects the protection ability of the hard protective layer 200.

[0044] Optionally, the shape of the connecting ring 220 is a circular ring or a polygonal ring, and is preferably a regular ring.

[0045] The hard protective layer 200 of the present application adopts the structure of multiple pieces of leather connected by connecting rings 220, which not only provides reliable protection, but also can be deformed flexibly, so that it can be adapted to different bones, thereby perfectly adapting to different people and different parts, and also has good air permeability. Therefore, the present application is flexible as a whole and can adapt to most people without the need for private customization, and the hard protective layer can be directly formed by 3D printing, thereby greatly reducing the cost of protective equipment customization, while taking into account the high protection performance and high comfort.

[0046] As an optional embodiment, refer to Figure 1The chain mail structure guard further comprises a buffer layer 300 arranged between the sponge layer 100 and the hard protective layer 200, wherein the buffer layer 300 has a hardness of 20-35A, and the buffer layer 300 can be made of a conventional shock-absorbing material, preferably, the buffer layer 300 is made of one of PU, TPV, TPU or TPE. The sponge layer 100, the hard protective layer 200 and the buffer layer 300 can be stacked in a conventional stacking manner in the prior art, such as mechanical structure fixation, bonding or sewing, etc. Preferably, the thickness of the intermediate layer is 3-12mm.

[0047] The buffer layer 300 has higher elasticity and is softer, so that the wearing comfort can be improved significantly, the buffer layer 300 has a large compression variable, so that the low-energy impact can be buffered better, and the pain can be reduced.

[0048] The chain mail structure guard can be used for football leg protection, roller skating protection, rugby protection, baseball protection, bicycle riding protection, motorcycle protection, skiing protection, basketball protection or other sports requiring protection. The structure of the chain mail structure guard can be adjusted according to the type of sports. For example, the chain mail structure guard with two-layer structure can be selected for football leg protection, roller skating protection, etc., and the chain mail structure guard with higher thickness and two-layer structure or the chain mail structure guard with three-layer structure can be selected for motorcycle protection, skiing protection, etc.
