Technical Field

The invention relates to a safety helmet, in particular to a safety helmet capable of absorbing multi-directional impact.

Background

The conventional safety helmet mainly comprises a rigid outer cover and a buffer layer filled in the rigid outer cover. When the cervical vertebra protector is impacted by external force, a part of energy is borne by the rigid outer cover, then a part of energy is absorbed by the buffer layer, and finally the rest part is borne by the head and the cervical vertebra. The types of external force impact can be roughly divided into radial impact, tangential impact and oblique impact, in the case of radial impact, the linear acceleration generated by the head may cause skull fracture or/and brain compression injury, and in the case of tangential impact, the angular acceleration generated by the head may cause brain or/and cervical vertebra to be damaged by shearing force. However, according to the statistics of injuries, pure radial impacts and tangential impacts are rare, and the most common type is an oblique impact combined by the two impacts, and when the oblique impact is received, the head simultaneously generates linear acceleration and rotational acceleration, so that serious injuries such as concussion, Traumatic Brain Injury (TBI), Subdural hematoma (SDH) or Diffuse Axonal Injury (DAI) are more easily caused.

In order to ensure sufficient safety of the helmet, some impact resistance tests are performed after the helmet is manufactured, but the general impact resistance tests are only used for radial impact, so that the helmet has good absorption capacity in the aspect of radial impact, but the absorption capacity provided by external force impact from other directions (especially oblique impact) is not ideal.

Detailed Description

The applicant hereby gives notice that, in the embodiments and drawings to be described hereinafter, the same reference numerals will be used to designate the same or similar elements or structural features thereof.

Referring to fig. 1 and 2, the safety helmet 10 of the present invention includes a helmet shell 20, a resilient support 30, and an auxiliary sliding member 40.

The cap shell 20 has an outer cover 21 and a buffer layer 22, the buffer layer 22 is fixed on the inner peripheral surface of the outer cover 21 by an adhesive, wherein the outer cover 21 is made of a rigid material such as hard plastic, and is mainly used for protecting the first layer, and the buffer layer 22 is made of a shock-absorbing material such as a foam material, and is mainly used for providing a shock-absorbing and buffering effect.

The elastic support 30 is made of an elastic material such as plastic. As shown in fig. 2, the elastic support 30 has two opposite top frame strips 32 and one side frame strip 34, one end of the two top frame strips 32 is integrally connected to the front end of the side frame strip 34, and the rear end of the side frame strip 34 is connected to an adjuster 36, so that the tightness of the side frame strip 34 is adjusted by the adjuster 36, and the side frame strip 34 can be adjusted to fit users with different head sizes to adjust the covering area. In addition, each of the top frame strips 32 and the side frame strips 34 is detachably disposed on the inner circumferential surface of the cushioning layer 22 of the cap shell 20, and is adhered to the inner circumferential surface of the cushioning layer 22 of the cap shell 20 by using an adhesive member (not shown), for example, as shown in fig. 3, a plurality of engaging portions 38 may be additionally disposed on the outer circumferential surface of each of the top frame strips 32 and the outer circumferential surface of the side frame strips 34, and the engaging portions 38 may be simultaneously engaged with one engaging hole 23 of the cushioning layer 22 in a one-to-one manner in addition to being adhered to the inner circumferential surface of the cushioning layer 22 of the cap shell 20 by using the adhesive member, so that the coupling strength between the top frame strips and the side frame strips can be increased, and the elastic support 30 can be detached at any time to adjust the tightness.

The sliding aid 40 has a cover cloth 41, and the cover cloth 41 is made of a low friction material such as lint. One surface of the surface cloth 41 is adhered to the inner peripheral surface of the elastic bracket 30 by an adhesive fastener (not shown) such as velcro, so that the sliding aid 40 can directly contact the other surface of the surface cloth 41 with the head 12 of the user by the restraining effect of the elastic bracket 30, and can be conveniently detached for cleaning when the surface is dirty. In addition, the sliding aid 40 further has a sliding aid 42 covered by the cover cloth 41, in this embodiment, the sliding aid 42 has two opposite base materials 43 and a plurality of flexible wires 44, the two base materials 43 are fixed with the cover cloth 41 by using an adhesive, the flexible wires 44 are disposed between the two base materials 43 and are not limited to a regular or irregular arrangement, and the two base materials 43 can be easily displaced relatively by the characteristics of the flexible wires 44. It should be added that the auxiliary slide member 40 in fig. 2 is exemplified by two units, one of which is located at the top of the head and the other is located around the head, however, in practice, the two units may be integrated into one unit, and even may be further divided into more than two units to meet different use requirements.

As can be seen from the above description, when the cap shell 20 is impacted by external force, a part of energy is received by the outer cover 21 of the cap shell 20, then a part of energy is absorbed by the buffer layer 22 of the cap shell 20, and then when the energy is transmitted to the sliding aid 40, as shown in fig. 3 and 4, the sliding aid 40 allows the cap shell 20 to slide relative to the head 12 through the sliding aid 42, so that the impact force received by the sliding aid 40 is converted into potential energy generated by the relative movement of the two, even the sliding aid 40 may slide with the head 12 due to the low friction characteristic of the surface cloth 41, so that the impact force received by the sliding aid 40 is further converted into heat energy generated by mutual friction, and finally the rest part is received by the head 12 and the cervical vertebrae. In other words, in the process of the safety helmet 10 of the present invention being impacted by external force, the impact force originally transmitted to the head 12 is absorbed and converted into other energy by using multiple modes such as deformation of the helmet shell 20 itself, sliding of the helmet shell 20 relative to the head 12, and friction between the surface cloth 41 and the head 12, so that damage to the head 12 caused by external force impact from different directions can be greatly reduced, and particularly under the condition of being impacted obliquely, the protection effect on the head 12 is further improved.

It should be further noted that the slip aid 42 may take a variety of different embodiments. For example: as shown in fig. 5 a-5 b, a slip-promoting medium 42 is a fluid, such as air or a gel, that creates a sliding effect on cap shell 20 through its deforming properties; referring to fig. 5c, the sliding aid 42 is composed of a plurality of balls 46, and the cap case 20 generates a sliding effect by the random rolling of the balls 46; as shown in fig. 5d, the sliding aid 42 is formed by two opposing base materials 48, each of the two base materials 48 has a low friction surface 50, and the low friction surfaces 50 of the two base materials 48 are opposite to each other and abut against each other, so that the two base materials 48 are easily displaced relative to each other to generate a sliding effect on the cap shell 20, and further, the base materials 48 may be made of a low friction material, such as Polyoxymethylene (POM), fluorine-containing resin (fluoroesin), Aramid resin (Aramid), plastic with chemical lubricant added, Polyimide (PI) filled with graphite, ultra-high molecular weight polyethylene (UHMWPE), and the like; as shown in fig. 5e, the sliding aid 42 is two opposite magnets 52, and a magnetic pole 54 (not limited to N-pole or S-pole) of the two magnets 50 has opposite polarity, so that the two magnets 50 are easy to be displaced relatively under the action of magnetic repulsion force, and the cap shell 20 generates a sliding effect; as shown in fig. 5f, the sliding aid 42 is a plate made of elastic material and has a plurality of concave portions 56 and a plurality of convex portions 58, the concave portions 56 and the convex portions 58 are connected in pairs and staggered, and the cap shell 20 generates a sliding effect through the elastic deformation of the sliding aid 42; finally, as shown in fig. 5g, the sliding aid 42 has a base material 60 and a plurality of flexible strip-shaped structures 62 connected to the base material 60, and the cap shell 20 generates a sliding effect by the characteristics of the flexible strip-shaped structures 62.
