Abstract
The invention discloses a safety helmet with a novel micro-structure shell. This helmet body adopts three layer construction, and concrete structure includes: the novel children's head comprises a shell 5, a buffer body 6, a lining 7 and a chin strap 8. By utilizing the bionics principle, the surface of the shell of the helmet adopts a microstructure consisting of polygonal textures and vertical reinforcing ribs. The design can increase the toughness of the helmet shell, reduce the risk of the helmet shell being punctured and further improve the protection capability of the helmet.
Description
Technical field
The present invention relates to the technical field of crash helmet, specifically refer to a kind of helmet with Novel Microstructure shell.This micro-structural effectively can improve the fracture toughness of helmet shell, thus improves the protective capacities of the helmet.
Background technology
In productive life, wear the helmet or safety cap prevents one of most effective method of head injury.The now conventional helmet mainly adopts three-decker: the hard skullcap formula shell of suitable thickness, the liner of certain thickness cushion and the head contact with people.Shell generally adopts the rigid plastics such as wear-resistant, resistance to compression is good ABS or PC, also has and adopts carbon fibre composite or metal material.This layer of Main Function stops impact perforation, expands lifting surface area, reduces local stress.Cushion is close to inside shell, often uses foamed material.The Main Function of this layer is kept out by the large deformation of foams to pass the impulsive force of coming from shell, apparatus with shock absorbing.But the rigid plastics that adopts of the shell of the existing helmet often toughness is inadequate, under larger impact force action, there is breakdown risk in shell.Because the material of cushion and liner is softer and loose porous, concentrated force cannot be born.Shell, once breakdown, directly will cause damage to head.And use metal material, the weight of the helmet will inevitably be increased, bring inconvenience to user.
The mechanical property of Queensland nut (macadamia) shell is very superior, and its housing can bear the external compressive load up to 2000N.By microscopic examination, can find that macadamia shell is obvious double-layer structure (Fig. 1): very thin (about 160 μm) but the very high crust layer of toughness; Thickness is between 1.5mm to 5mm, but very loose cork layer.The outer surface of crust layer is dispersed with the texture be made up of polygon.The radial fiber perpendicular to case surface is dispersed with in polygonal corner location.The elastic modelling quantity of this fiber and hardness are all large than the fiber of parallel surfaces distribution, serve the effect of reinforcement in crust layer structure.There are some researches show, polygon texture and radial fiber are the reasons that crust layer has high tenacity.Therefore the toughening mechanism of Queensland nut shell is applied in the design of the shell mechanism of the helmet by the present invention, improves the protective capacities of crash helmet.
Summary of the invention
The object of the invention is, for the deficiency of existing helmet shell in opposing destruction, to utilize bionics principle, devise a kind of shell with the helmet of Novel Microstructure, to improve the protective capacities of the helmet.
In order to solve above technical problem, the present invention is achieved by the following technical solutions: a kind of helmet having Novel Microstructure shell, and its helmet body adopts three-decker.Concrete structure comprises: the shell of the helmet, cushion, liner, chin belt.Shell adopts fibre reinforced composites.The outer surface of housing adopts and mixes by pentagon and hexagon the texture formed, and polygonal diameter is 30 μm to 50 μm.Columned reinforcement is being provided with perpendicular on the direction of outer surface.The diameter of this reinforcement is between 4 μm to 6 μm, is distributed on the angle point of polygon boundary, and imbeds among shell.Cushion adopts foamed material, such as EPS, EPO, EPP etc.By certain thickness density, the low and material of quality softness is formed liner, such as fabric, sponge etc.The inner surface of this layer and head contact.An entirety is connected into by gluing between each layer.
Adopt technique scheme, the toughness of helmet shell will improve a lot, and this will reduce the breakdown risk of helmet shell greatly.The cushion foamed material of the helmet, can delay the action time of impacting, for head provides buffer protection.Also can alleviate the weight of the helmet in addition to a certain extent, make user more comfortable.Liner adopts soft material, on the one hand can supplementing as helmet shell and cushion shock-absorbing function, also can improve the comfort level of use on the other hand.The effect of chin belt 8 is fixed together closely by the inner casing of head and safety cap.
The present invention is the improvement to helmet buffer structure, does not relate to the concrete configuration of the helmet.Therefore the present invention can be applied to the helmet of different designs configuration.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As shown in Figure 3, the present invention is made up of four parts, and ecto-entad is followed successively by: helmet shell 5, cushion 6, liner 7 and chin belt 8.Wherein helmet shell 5 adopts fibre reinforced composites.Its microstructure adopts the configuration similar with Queensland nut crust layer: the outer surface of housing adopts and mixes by pentagon and hexagon the texture 51 formed, and polygonal diameter is 30 μm to 50 μm; Perpendicular to the direction of outer surface being provided with columned reinforcement 52; The diameter of this reinforcement is between 4 μm to 6 μm, is distributed on the angle point of polygon boundary, and imbeds among shell.Cushion 6 is close to the inner surface of shell 5, adopts foamed material, such as EPS, EPO, EPP etc.By certain thickness density, the low and material of quality softness is formed liner 7, such as fabric, sponge etc.The inner surface of this layer and head contact.An entirety is connected into by gluing between each layer.Chin belt 5 and shell are rigidly connected, and head and helmet shell can be fixed together closely.
Helmet shell 5 adopts the microscopic structures of polygon texture 51 and vertical stiffeners 52, can strengthen the toughness of shell, reduces the risk that helmet shell is breakdown.
