Abstract

本发明涉及一种柔性的运动防护护甲、护具及其成型方法，由防护护甲构成与人体部位相适配的整体式的护甲片，护甲片内嵌于服饰获得全防护结构的防护护具，实现对人体全方位保护；护甲片中核心的防护层由泄力减震层、柔性复合层、缓冲层经界面热贴合构成一体，柔性复合层由间隔层设的纤维织物层、树脂层热压构成，纤维织物层层内孔隙被树脂层的树脂浸润形成纤维树脂共存；护具受击打时，力经纤维织物层缓冲而法向扩散，达到泄力效果，结合泄力减震层和缓冲层的共同防护，被击打时能明显感觉力的扩散；并且本发明的护甲作为运动护具重量轻盈，穿戴舒适，尤其适用于武术兵器击打类的运动护甲，特别是在高频长效类击打运动中的防护。

The present invention relates to a flexible sports protective armor, protective gear and a molding method thereof. The protective armor constitutes an integral armor piece adapted to a human body part, the armor piece is embedded in clothing to obtain a protective gear with a full protective structure, thereby realizing all-round protection of the human body. The core protective layer in the armor piece is formed into an integral body by a force-releasing and shock-absorbing layer, a flexible composite layer and a buffer layer through interface thermal bonding, the flexible composite layer is formed by hot pressing a fiber fabric layer and a resin layer arranged as an interval layer, and the pores in the fiber fabric layers are infiltrated by the resin of the resin layer to form a coexistence of fiber and resin. When the protective gear is hit, the force is buffered by the fiber fabric layer and diffused in a normal direction to achieve a force-releasing effect. Combined with the joint protection of the force-releasing and shock-absorbing layer and the buffer layer, the diffusion of the force can be clearly felt when being hit. In addition, the armor of the present invention is lightweight as a sports protective gear and comfortable to wear, and is particularly suitable for sports armor for martial arts weapon striking, especially for protection in high-frequency and long-acting striking sports.

Description

Flexible sports protective armor, protective tool and forming method thereof
Technical Field
The invention relates to the technical field of sports protective clothing, in particular to a flexible sports protective armor, a flexible sports protective clothing and a forming method of the flexible sports protective armor.
Background
The utility model provides a protective equipment, is to be in beating the motion and protect the human body, avoids the instrument of injury, and current protective equipment adopts nylon or cold rolled steel billet as the protection main material generally.
Because of the inherent rigidity of nylon or steel plate materials, namely the materials cannot be easily deformed and bent obviously under the conventional condition, if the protective tool is manufactured into an integral armor, the protective tool can play a role in omnibearing protection, but has poor activity or flexibility, for example, when the armor is manufactured into an integral armor, people can have obvious resistance when bending down to squat; the middle century rider plate and armor are heavy and light in mobility, and the whole plate and armor have no mobility although the horse increases the flexibility.
In the prior art, in order to balance protection and mobility, the protective tool is usually manufactured into a broken armor splicing structure, and in the case of ancient infantry, most of the protective tool is worn by the broken armor and the scaly armor, and the protective tool is formed by combining a plurality of tiny broken armor. The split joint type protective clothing for broken nails needs to splice the broken nails one by one according to the preset, and the manufacturing process is complicated; on the other hand, although broken armor is adopted, the whole weight of the protector is still heavier, and is usually 10-25 kg; moreover, the split joint type broken armor is to sacrifice the omnibearing protection of the whole armor, and the partial protection is replaced by the partial action flexibility of the wearer.
In addition, current nylon protective equipment of moulding plastics, when beating and surpassing the tolerance, the protective equipment can split, fracture, fall the sediment, broken piece extremely easily causes personnel secondary injury in the motion, and the safety in utilization is low, and the nylon protective equipment belongs to low frequency protective equipment, loses the guard action promptly after the atress is damaged, can not protect the motion by high frequency long-term.
The existing market also has a soft foam sports protective tool which is low in cost, but the sports protective tool only depends on soft thick foam to perform sports protection, has poor impact resistance and impact resistance, has a general protective effect, plays a role in buffering, is in a large posture after being worn, has general mobility and can only be applied to a simple sports scene.
