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 micro-structural shell.This micro-structural can effectively improve the fracture toughness of helmet shell, thereby improves the protective capacities of the helmet.
Background technology
In productive life, wearing the helmet or safety cap is to prevent one of effective method of head injury.The helmet commonly used now mainly adopts three-decker: hard skullcap formula shell, certain thickness cushion and the liner that contacts with people's head of suitable thickness.The general rigid plastics such as the ABS wear-resistant, that resistance to compression is good or PC that adopt of shell also have the carbon fibre composite of employing or metal material.The main effect of this layer is to stop to impact to penetrate, and enlarges lifting surface area, reduces local stress.Cushion is close to the shell inboard, often uses foamed material.The main effect of this layer is to keep out from shell by the large deformation of foams to pass the impulsive force of coming, and absorbs impact energy.Yet often toughness is not enough for the rigid plastics that the shell of the existing helmet adopts, and under bigger impact force action, there is breakdown risk in shell.Because the material of cushion and liner is softer and loose porous, can't bear concentrated force.Shell is in a single day breakdown, will directly cause damage to head.And the use metal material will inevitably increase the weight of the helmet, has brought inconvenience to the 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 the Queensland nut shell is tangible double-layer structure (Fig. 1): extremely thin (about 160 μ m) but the very high crust layer of toughness; Thickness at 1.5mm between the 5mm, but very loose cork layer.The texture that is distributing and formed by polygon at the outer surface of crust layer.Distributing perpendicular to the radial fiber of case surface in polygonal corner location.The elastic modelling quantity of this fiber and hardness are all big than the fiber that parallel surfaces distributes, and have played the effect of reinforcement in the crust layer structure.There are some researches show that polygon texture and radial fiber are the reasons that crust layer has high tenacity.Therefore the present invention is applied to the toughening mechanism of Queensland nut shell to improve the protective capacities of crash helmet in the design of shell mechanism of the helmet.
Summary of the invention
The objective of the invention is to utilize bionics principle at having helmet shell now in the deficiency aspect the opposing destruction, designed a kind of shell with helmet of novel micro-structural, 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 that novel micro-structural shell is arranged, 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 by pentagon and hexagon and mixes the texture that constitutes, and polygonal diameter is that 30 μ m are to 50 μ m.Be provided with columned reinforcement in the direction perpendicular to outer surface.The diameter of this reinforcement be 4 μ m between the 6 μ m, be distributed on the angle point that polygon has a common boundary, and imbed among the shell.Cushion adopts foamed material, such as EPS, EPO, EPP etc.The material that liner is low by certain thickness density and quality is soft constitutes, such as fabric, sponge etc.The inner surface of this layer contacts with head.Connect into an integral body 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, the action time that can delay to impact is for head provides buffer protection.Also can alleviate the weight of the helmet in addition to a certain extent, make the user more comfortable.Liner adopts soft material, can be used as replenishing of helmet shell and cushion shock-absorbing function on the one hand, also can improve the comfort level of use on the other hand.The effect of chin belt 8 is that the inner casing with head and safety cap is fixed together closely.
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.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment 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 the Queensland nut crust layer: the outer surface of housing adopts and mixes the texture 51 that constitutes by pentagon and hexagon, and polygonal diameter is that 30 μ m are to 50 μ m; Be provided with columned reinforcement 52 in the direction perpendicular to outer surface; The diameter of this reinforcement be 4 μ m between the 6 μ m, be distributed on the angle point that polygon has a common boundary, and imbed among the shell.Cushion 6 is close to the inner surface of shell 5, adopts foamed material, such as EPS, EPO, EPP etc.The material that liner 7 is low by certain thickness density and quality is soft constitutes, such as fabric, sponge etc.The inner surface of this layer contacts with head.Connect into an integral body by gluing between each layer.Chin belt 5 is rigidly connected with shell, head and helmet shell can be fixed together closely.
Helmet shell 5 adopts the microcosmic configuration of polygon texture 51 and vertical reinforcement 52, can strengthen the toughness of shell, reduces the breakdown risk of helmet shell.
