Abstract

The utility model discloses a lining structure of a lining structure, which comprises a helmet shell, a lining body combined inside the shell and a plurality of buffering units distributed in the lining body, wherein the lining body is formed by lower-density and soft material and is tightly combined inside the hard shell; the buffering units are hollow columns made of shock-absorbing material with certain strength, and are distributed in the lining body at intervals; and the soft lining body is matched with the higher-strength buffering units, therefore, the structure can fully absorb, disperse and reduce external impact and shock, effectively reduces the strength of impact force and shock applied to unit area of human head, and has better safety protecting effect.

Description

Helmet inner lining structure

Technical field

The utility model relates to the technical field of safety cap, specifically is meant a kind of helmet inner lining structure that can effectively disperse the safety cap of impulsive force.

Background technology

The structure of Generally Recognized as safe cap is the headpiece case of being made by the material of a tool certain degree of hardness, and internal layer is in conjunction with the liner of the certain thickness high density foaming of tool shock-absorbing material, both combinations, in case be subjected to external force collision, can keep out or absorption portion external force by this hard shell and foaming liner, to reduce and to disperse the impulsive force of outside, reach the protection user and reduce the purpose that injures, but the material that the inner lining structure of existing safety cap adopts is hard and be a monolithic construction of coupling housing, the ability of elastically deformable shock-absorbing buffering is not good, as Fig. 1, shown in 2, when being subjected to impacting, this liner can only transmit and the absorption impulsive force in the small range internal strain, disperses the ability of impact relatively poor, can't carry out fully effective diffusion for concentrated and the high impulsive force of intensity, make most of external force still concentrate effect, make user's head still be subjected to bigger collision, for the higher impact of intensity, the effect of shock-absorbing buffering is undesirable; Therefore there is the dealer to design at housing and foam to increase between liner the lower and soft bed course of one deck density is set, increase cushioning effect, in the hope of can with the impulsive force concentrated to around disperse, weaken, reduce bump, but its final effect of buffering external force of disperseing is still not ideal enough in the practical application human body head.

The utility model content

For this reason, the purpose of this utility model is to provide a kind of helmet inner lining structure, has and can effectively disperse impulsive force, reaches the characteristics of preferable security protection.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of helmet inner lining structure comprises a headpiece case, is incorporated into the inner lining body of this housing inboard and is laid in plural buffer cell in this inner lining body; Wherein inner lining body is made of the lower and soft material of density, combines closely in the housing inboard of this hard, and this buffer cell is the hollow column that the vibration absorptive material of the certain intensity of a tool is made, spaced apart being located in the inner lining body.

The utility model adopts such scheme; the effect of matching of the inner lining body of its helmet liner by softness and stronger buffer cell; can fully absorb, disperse, reduce outside impact and concussion; effectively reduce impulsive force and the impact strength that acts on the human body head unit are, have better safeguard protection effect.

The specific embodiment

Cooperate shown in Fig. 4,5, helmet inner lining structure of the present utility model comprises a headpiece case 1, be incorporated into the inner lining body 2 of this housing 1 inboard and be laid in plural buffer cell 3 in this inner lining body 2; Its middle shell 1 is made for hard material, and inner lining body 2 is to be made of the lower and soft material of density, combines closely in the inboard of housing 1, contacts with user's head; And buffer cell 3 is hollow columns of being made by the vibration absorptive material of the certain intensity of tool, spaced apart being located in the inner lining body 2.

Helmet liner adopts said structure, when being subjected to external impacts, as shown in Figure 6, the impulsive force of some minuents or moderate, when not reaching the intensity level that makes buffer cell 3 strains, can effectively absorb, relax high speed impact power by inner lining body 2 soft characteristic, and part can be impacted to periphery and disperse to transmit; Concentrate and high-intensity external impacts for application point, the utility model can be by the stressed strain of buffer cell 3 hollow columns, assimilate the part impulsive force, and the strain by this buffer cell 3 with impulsive force to around disperse, because buffer cell 3 is located in the inner lining body 2, therefore inner lining body 2 around can effectively impulsive force being dispersed on a large scale, cooperate soft inner lining body 2 further fully to dissolve strong wallop, and after impacting, this inner lining body 2 and buffer cell 3 be elastic recovery deformation state not extremely naturally rapidly.

As seen; the effect of matching of the inner lining body 2 of helmet liner of the present utility model by softness and stronger buffer cell 3; can fully absorb, disperse, reduce outside impact and concussion; final impulsive force and the impact strength that acts on the human body head unit are that effectively reduce; be illustrated in figure 3 as and adopt the concussion index of commonly using helmet liner; Figure 7 shows that the concussion index that adopts helmet liner of the present utility model; as seen from the figure, the utility model is compared and is commonly used structure and really have better safeguard protection effect.

Claims

1. helmet inner lining structure is characterized in that: comprise a headpiece case, be incorporated into the inner lining body of this housing inboard and be laid in plural buffer cell in this inner lining body; Wherein inner lining body is made of the lower and soft material of density, combines closely in the housing inboard of this hard, and this buffer cell is the hollow column that the vibration absorptive material of the certain intensity of a tool is made, spaced apart being located in the inner lining body.
