DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following clearly and completely describes the technical solution in the embodiments of the present invention in combination with the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are only part of the embodiments of the present invention, not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

[0027] Referring to FIGS. 1-5, the present disclosure provides one technical solution: a helmet with a split type skeleton structure, including a helmet body 1. The helmet body 1 is composed of a head guard 11 and a chin guard 12 which are separated, and the head guard 11 and the chin guard 12 are mounted through cooperation between a fastened spliced skeleton 2 and a plug pin 23. By means of the plug pin 23, the spliced skeleton 2 can be quickly spliced; and meanwhile, quick assembling and disassembling between the head guard 11 and the chin guard 12 are facilitated.

[0028] In particular, the spliced skeleton 2 is composed of two skeleton connection members 21 arranged inside the head guard 11 and a chin skeleton 22 arranged inside the chin guard 12. The spliced skeleton 2 is composed of the skeleton connection members 21 and the chin skeleton 22, so that when the spliced skeleton 2 is machined, the skeleton connection members 21 and the chin skeleton 22 are subjected to split machining, which reduces the mold opening cost during skeleton manufacturing. Hollows of a surface of the chin skeleton 22 is fixedly connected with a plurality of one-piece structured reinforcing ribs 221. The plurality of reinforcing ribs 221 may be machined in one piece during the machining of the skeleton connection members 21 and the chin skeleton 22. The plurality of reinforcing ribs 221 may be arranged in a honeycomb shape or a strip shape, so that the skeleton has higher structural strength while it has light weight.

[0029] In this embodiment, the helmet body 1 is of a three-layer structure; an expanded polystyrene (EPS) liner 101 is located at a middle layer; the EPS liner 101 is wrapped outside the skeleton connection members 21 and the chin skeleton 22; an inner side of the EPS liner 101 is adhered with an EPS inner layer 102; and an outer side of the EPS liner 101 is adhered with a polycarbonate (PC) surface layer 103.

[0030] Specifically, the helmet also adopts a three-layer structure. After the skeleton has been manufactured, the EPS liner 101 is injection-molded outside the skeleton connection members 21; the EPS liner 101 can wrap the skeleton and also facilitating subsequent machining of the EPS inner layer 102 and the PC surface layer 103, so that the helmet has relatively good buffer property and wear comfort; and the PC surface layer 103 located on the outermost layer also ensures that the helmet has relatively high structural strength and ensures the safety of the helmet.

[0031] In this embodiment, the bottom of one side of each skeleton connection member 21 is fixedly connected with a one-piece structured T-shaped sliding clamping head 211; the top of one side of each skeleton connection member 21 is fixedly connected with a one-piece structured sleeve member 212; a first plug hole 213 is formed in a surface of the sleeve member 212; a plug opening 222 and a clamping opening 223 are formed in one side of each of two ends of the chin skeleton 22 in sequence from top to bottom; the plug opening 222 communicates with the inside of the clamping opening 223, and a width of the clamping opening 223 is less than that of the plug opening 222; the T-shaped sliding clamping head 211 is fastened to the clamping opening 223 after passing through the plug opening 222; the top of each of two ends of the chin skeleton 22 is fixedly connected with a one-piece structured sleeve head 224; the sleeve head 224 is matched with the sleeve member 212 in size and is plugged and fixed with the sleeve member 212; a second plug hole 2241 is formed in a surface of the sleeve head 224; a sunken pin hole 111 penetrating through the EPS inner layer 102 and the EPS liner 101 is formed in the inner side of the head guard 11; and the sunken pin hole 111 is plugged and fixed with the second plug hole 2241 and the first plug hole 213 through the plug pin 23.

[0032] Specifically, when the head guard 11 and the chin guard 12 are assembled and disassembled, only the skeleton connection members 21 and the chin skeletons 22 are assembled and disassembled.

[0033] When the skeleton connection members 21 and the chin skeleton 22 need to be mounted, the T-shaped sliding clamping heads 211 are firstly plugged into the plug openings 222, and the sleeve members 212 then directly face the sleeve heads 224; the chin skeleton 22 is then upwards pushed to enable the T-shaped sliding clamping heads 211 to be fastened in the clamping openings 223 for locking; at the same time, the sleeve heads 224 are completely plugged into the sleeve members 212; finally, one end of each plug pin 23 passes through the sunken pin hole 111 and is plugged and fixed with each second plug hole 2241 and each first plug hole 213, so as to realize locking of the skeleton connection members 21 and the chin skeleton 22, thus quickly completing the mounting of the head guard 11 and the chin guard 12; and during dismantling, the operations are performed reversely.

[0034] In this embodiment, open slots 112 with inclined “7”-shaped sections are formed in positions of the head guard 11 directly facing the skeleton connection members 21, and fastening bulges matched with the open slots 112 are arranged at positions of the chin guard 12 directly facing the chin skeleton 22.

[0035] Specifically, when the head guard 11 and the chin guard 12 are assembled, the open slots 112 and the fastening bulges are fastened with each other; and under the plugged locking action of the plug pins 23, the chin guard 12 is prevented from falling off from the head guard 11.

[0036] In this embodiment, the skeleton connection members 21 and the chin skeleton 22 are made of different materials.

[0037] Specifically, the skeleton connection members 21 and the chin skeleton 22 of different materials may be adjusted according to a production need of the helmet, so that the customization degree is higher, and the flexible selectivity of users is also improved.

[0038] The contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in the art. Although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art still can modify the technical solutions disclosed in the foregoing various embodiments, or make equivalent replacement to partial technical features.
