Description

The reinforced structure of crash helmet

Technical field

The utility model relates to a kind of reinforced structure and manufacture method thereof of crash helmet; Refer to that especially cap body that a kind of application buffering (foaming) material forms is coated the Combination Design of a hood configuration body, with the whole reinforced structure of composite molding one, make the general safety helmet can manufacture more lightly and there is the technological means person of high security.

Background technology

Apply that a plastic casing is closely sealed to be fixed on one and to have in the vacuum forming device of hat module, what coordinate an expanded material adds the shock-resistant obturator of thermosetting one, and make closely coated foam-filled body of this plastic casing, and complete a crash helmet or helmet structure, be existing skill.For example, the Patent Cases such as the U.S. No. 4466138 " Safety Helmet with A Shell Injected from Thermoplastics And Method for The Manufacture of Said Helmet ", TaiWan, China No. 85101810 " safety cap manufacture method ", provide typical embodiment.

One about this class crash helmet in the problem aspect structural design and security is, the helmet of the coated foam-filled body of glue shell, mainly with outside glue shell, provide opposing sharp object to impact the ability piercing through, to this foam filler, provide peripheral cohesion simultaneously, allow the hard crisp foam-filled body of this material behavior, when being subject to powerful external impacts, enough buffer intensities can being provided and avoiding foam-filled body to produce and break and buffer loss effect.

This is because each foam-filled body of general foaming type padded coaming belongs to a closed structure body; The external margin of each adjacent expanded beads or border, in heating process, because the inflexible limit of mould forms the irregular combination kenel fitting tightly on surface each other.They utilize the above-mentioned irregular relation fitting tightly when suffering blunt formula external impacts, absorb this impulsive force, and make impulsive force disperse to transmit towards all directions.When foam-filled body suffers the powerful impact of sharp objects, the easy impact strength because of this sharp-pointed pattern, act on the position of fitting with edge between above-mentioned each expanded beads surface, and cause the border generation that each expanded beads engages to peel off, decompose and break, resistance to collision characteristic and the whole cushioning effect that should provide of each expanded beads has been provided; Also make them this cannot be impacted to strength and effectively on average disperse to be delivered to cap body (or foam-filled body) regional.

Above-mentioned existing helmet structure particularly; when suffering the situation of lateral impact or compressing; these described lateral action power or pressure are known from experience and are produced a bending shearing cap; described bending shearing damages for only having the coated cap of one-sided glue shell to know from experience, the head protection effect that cannot improve.

Therefore, traditional technology remains to strengthen the mode of (thick) outside glue shell at present, opposing for sharp object impact and side impacting force is provided, and the outside to above-mentioned foaming type padded coaming (or foam-filled body) provides coated polymerization, to increase these described foaming type padded coamings when being subject to all directions and impacting, can not produce, break and lose its impact resistance.But also, because under the requirement of high security, constantly increase thickness and the weight of this glue shell and/or this foaming type padded coaming; Relative, also increased the volume of whole crash helmet and caused prestowage person's added burden.

In order to improve above-mentioned situation, old law has also disclosed a kind of application one deck or multiple layer fibrage, the ability of coming this foam-filled body opposing sharp object of assistant reinforcement to impact.But just as those people that have the knack of this skill know, it is cumbersome and unstable on manufacturing operation.And, if consider sufficient protective capacities, add more multi-layered fibrage, can significantly increase again the integral body weight summation of (with cap body).Moreover these described fibrages, in autologous configuration aspects, lack ideal self enabling capabilities.Therefore, this helmet, when being subject to the weight power of different kenels (particularly side pressure) or impact force action, cannot provide enough bearing strengths.

Therefore; consider the resistivity of the helmet when being subjected to different kenel impulsive force; and improve this fibrage and cannot improve the disappearance that the enough side direction protection mechanisms of whole foam-filled body are provided; if strengthen this plastic casing and foam-filled body in the mode strengthening or thicken merely; body size and weight that obviously again will the whole crash helmet of impact, and that this situation is not for we is desired.

Representational, these references have shown the design skill at structure and manufacture view at relevant crash helmet; They also reflect the combining structure of these helmets or glue shell and internal structure body, in testing experiment and the actual situation of using, and more existing problems.If the internal combination structure of this outside helmet of overline design consideration or glue shell and foam filler, its structural strength can significantly be promoted, and can further meet in design make simplify and the condition of high security under, make its structure be different from those existing, and provide one comprehensively to protect and enabling capabilities, can change it for the transmission dispersion kenel of external impact force (or applied external force), and effectively improve the disappearance of old law.

For example, consider to make the existing structure cannot be by all types of impact strength in outside, effectively via internal structure body (or foam-filled body), disperse to be passed to the regional of whole cap body, allow the situation that the various piece of this structure all can all types of impact strength of average load, obtain significantly and improve; And further this outside glue shell of thinning or remove the structure that fibrage is arranged, makes the combining structure of this cap body have the structural strength that more existing skill is higher on all directions or region, so that comprehensively carry external impact or lateral impact pressure; And, meeting under the condition of this high security, make the helmet there is the significantly structure kenel of light-weight design, can increase whole can range of application.

And these problems in above-mentioned existing reference all not by concrete teaching or announcement.

The specific embodiment

Refer to Fig. 1, Fig. 2, the reinforced structure of crash helmet of the present utility model is selected an embodiment explanation that the crash helmet that motion wears is provided; This crash helmet can be also the engineering helmet, climbing helmet, horse cap or drive bicycle, locomotive, skiing ... Deng time half-mask (Fig. 1～Fig. 8) and all cover (Fig. 9) the safety cap kenel worn.Comprise the combination (or claiming time assembly) of cap body and a structure of the formation of a buffering (foaming) material; Generally with Ref. No. 10,20, represent respectively.Described cap body 10 coordinates a mould or forming module 40 injection buffering (foaming) materials to form, and 10 definition of cap body have a top area 11 and neighboring area 12.

Substantially, forming module 40 comprises the hat chamber 43 jointly defining between a female module 41, a male module 42 and female, male module 41,42, in this hat chamber 43, contained structure body 20 and/or glue shell 30 are provided and have injected buffering (foaming) material to form the space of cap body 10.Fig. 2 has also described glue shell 30 and has been provided with the structure kenel that passage 31 combines desmachymes 32; Desmachyme 32 can be used to keep out outside sharp object and thrusts cap body 10.

Fig. 1, Fig. 2 have shown that this structure 20 selects plastic cement or other similarly to have an elastomeric material, to form a dictyosome organizational patterns that approaches the hat profile of hemisphere face body.This structure 20 at least forms an array (silver) organizational structure by most bars 21,22, and is formed on the geometric form mesh 23 between this bar 21,22; For embodiment explanation, this bar is defined as vertical bar 21 and horizontal bar 22.Vertical bar 21 and horizontal bar 22 can be uniformly-spaced to arrange kenel, and form the mesh 23 of square or rectangular profile.

That is to say, according to pattern or the specification of crash helmet, the shape (or profile) of the arranging density of this longitudinal and transverse bar 21,22 and mesh 23 can be corrected or change.

In adopted embodiment, to top area 11 and neighboring area 12 that should cap body 10, these structure 20 definition have the first district 20A to be connected the Second Region 20B of the first district 20A with one.And, coordinate this forming module 40, make this buffering (foaming) material (or cap body 10) through mesh 23, the strengthening kenel (or bell-type complex intensifying structure) that is combined into one of coated (bond) first 20AHe Second Region, district 20B.Described integral body strengthening kenel (the compound kenel of cap body 10 and structure 20) is defined as time assembly; And, provide glue shell 30 coated combinations this assembly, and jointly form a helmet assembly 100.
