Abstract

The invention relates to a protective helmet for the head, consisting of an internal shock absorber body (3) and an outer casing. The internal shock absorber body (3) includes an inner reinforcement structure (5) made of threads (6) comprising a fibre core and a covering of a resin and carbon nanofibres.

Description

For the crash helmet of head

Describe

Technical field

The present invention relates to the crash helmet for head; it belongs to the kind comprising internal vibration absorbent body and external shell; this internal vibration absorbent body is made up of foamed synthetic resin such as expanded polystyrene (EPS) usually; have built-in internal reinforcing structure, this external shell is made up of thermoformable plastic material such as Merlon, PVC or ABS etc.

Background of invention

Be by the problem of the helmet that aforesaid way is formed, the protection that they provide is relatively low, is the fact because shock absorption body upon impact can easily damage in essence.

Making such helmet have more resistive known method is that internal reinforcing structure is assembled to internal vibration absorbent body.

About this, it is possible for quoting Canada Documents CA1335027, this documents describes the helmet with stiffener, and this helmet comprises: foamed synthetic resin body, the feature of this body is porous, collision time easily damage; And fastening element, this fastening element is extending longitudinally in the next top of the helmet; With multiple stiffener, the low portion of the plurality of stiffener is combined securely with the stiffener at top.

US5619756 describes a kind of helmet with expanded polystyrene (EPS) body, and this body has the built-in stiffening ring with housing interconnection.

EP1856997 describes a kind of helmet, and it comprises the body with internal reinforcing structure, and this internal reinforcing structure is made up of unidirectional filiform.

In above-mentioned all situations, be built in the resistance that the intrinsic stiffener of shock absorption can not increase the helmet significantly, this is the mode due to stiffener composition, usually due to the essence that it is made up of plastic material, also due to mode that described stiffener distributes in whole shock absorption body.

Invention describes

The present invention is intended to use the initial helmet disclosing kind to eliminate problem set forth above, this helmet has and is built in the intrinsic ruggedized construction of shock absorption, due to this ruggedized construction, the resistance of the helmet can increase significantly, thus the weight and volume of shock absorption body may be reduced, and and then the volume and weight of the reduction helmet.

According to the present invention, be built in the intrinsic internal reinforcing structure of shock absorption to be made up of filiform, the overcoat that this filiform comprises fiber core and is made up of carbon resin and nanofiber, this nanofiber preferably has graphene-structured, is after this called as " graphene nano fiber ".Filiform will be distributed in whole shock absorption body, form the net being built in the inside of described body.

The filiform core of a part being used for being formed internal reinforcing structure can be made up of synthetic fibers or natural mineral fiber, such as aromatic polyamides, carbon, basalt or glass etc.

Being used for the resin of a part of the jacket layer forming filiform can be epoxylite or heat-resistant polymer, hardening when this epoxylite or heat-resistant polymer are on catalyst action is to it.

Graphene nano fiber can be carbon nano-fiber, Graphite Nano Fiber or CNT, i.e. screw-shaped carbon structure.

The part by weight of resin that is that graphene nano fiber can be used to the jacket layer forming filiform and described layer is between 0.1% and 5%, and the part preferably between 0.5% and 1.5%.

Graphene nano fiber makes internal reinforcing structure rigidity and have resistance more, therefore may reduce overall weight and the volume of the helmet, thus make the helmet lighter equally.

When colliding; although the helmet damages; but it is regardless of splinter; this is due to the fact that in the internal vibration absorbent body be made up of expanded material have built-in skeleton or net; the fragment that the helmet has been fragmented into by this skeleton or net or part fastening and keep together, therefore contribute to absorbing the energy that impacts and larger user's protection be finally provided.This effect is realized by the filiform that distributes in the whole quality of internal vibration absorbent body, and this effect can also owing to the structure of described filiform, and this filiform is made by fiber core with the silicone jacket of graphene nano fiber.

Accompanying drawing is sketched

Drawings describe the formed according to the present invention helmet being used as its non-limiting example:

-Fig. 1 is the rearview of the helmet.

-Fig. 2 is the upper plane figure of the helmet shown in Fig. 1.

-Fig. 3 provides and view similar shown in Fig. 2, although wherein in order to show reinforcing framework, the part of the outside helmet and internal vibration absorbent body is saved.

-Fig. 4 is included in the perspective view of the ruggedized construction in the helmet shown in Fig. 1-Fig. 3.

-Fig. 5 is the perspective view of the amplification of the part of the filiform forming the structure shown in Fig. 4.

Embodiment describes in detail

The helmet described in the rearview of Fig. 1 and the upper plane figure of Fig. 2 is the helmet kind be generally used in cycling; but it should be noted that; the present invention can be applied to the helmet with any structure; as the protection element for various activity (such as, skiing, climbing, hockey etc.).

The helmet in the example that accompanying drawing is described has outside recess (1) for reducing its weight and opening (2), and be made up of shock absorption body (3) (see Fig. 3) and external shell (4) (see Fig. 1 and Fig. 2), this shock absorption body (3) copies recess (1) and opening (2), this external shell (4) copies the outer surface of internal vibration absorbent body (3), and this external shell (4) also connects and is fixed to the outer surface of this internal vibration absorbent body (3).

Internal vibration absorbent body can be made up of Foamex (such as, expanded polystyrene (EPS)), and external shell can be made up of thermoforming plastic (such as, Merlon, PVC, PP etc.).

The helmet is equipped with fastener, the helmet is fastened to head, these fasteners are known kinds, such as, be made up of band.

As can be seen in Figure 3, shock absorption body (3) has built-in internal reinforcing structure (5), and this internal reinforcing structure (5) perspective ground shows in the diagram and distributes in whole shock absorption body, thus forms net.

Internal reinforcing structure (5) is formed by filiform (6), as seen in Fig. 5, this filiform (6) comprises the core (7) and by resin (9) (such as of fiber, epoxy resin) and the overcoat (8) that formed of graphene nano fiber (10), this graphene nano fiber (10) makes resin rigidity and have more resistance more.

As inferred from Fig. 4, the filiform (6) in structure (5) distributes in the mode extended between the opening (2) in internal vibration absorbent body, thus forms complete net or net in described body.
