Abstract
The invention provides an electric bicycle helmet. The electric bicycle helmet is characterized by having a three-layer structure, namely a rigid shell, an elastic cushion layer and a foam lining pad from outside to inside sequentially, wherein the rigid shell is made from an ABS (acrylonitrile butadiene styrene) engineering material, the elastic cushion layer covers the inner side of the rigid shell and is made from EPS (expandable polystyrene), and the foam lining pad is adhered onto the inner side of the elastic cushion layer and is made from a polyethylene material. Compared with the prior art, the electric bicycle helmet disclosed by the invention has the advantages that the shell is made from the high-impaction-resistant ABS engineering material, and the EPS cushion layer with good compressive property and the foam lining pad are internally arranged so that three protection layers prevent the head of a user from damage in various directions; and a coverage surface of the lining pad and a chin belt is large so that the protection effect is improved to the largest extent when the head is impacted and a cushioning function is exerted.
Description
Technical field
The present invention relates to a kind of crash helmet, particularly a kind of electric bicycle helmet.
Background technology
In recent years, electric bicycle progressively replaces bicycle becomes preferably walking-replacing tool of people.But along with being on the increase of vehicle, the traffic accident that electric bicycle causes constantly increases, and according to incompletely statistics, in present all kinds of reason traffic accidents, the traffic accident relevant with electric bicycle accounts for more than 50%.In the electric bicycle process of riding, clash into the accident of falling down and to cause very large infringement to head.The reason of wearing bicycle helmet is very simple also very important, protection head, Harm reduction.Report according to the research of American Highway security insurance shows: U.S. 1999 by bike dead number has 98% not helmet, and the danger coefficient that the people who helmets in the bump accident sustains a severe head injury them has reduced 85%, in surpassing the by bike death by accident of 500 examples every year, it is that head is subject to mortal injury and causes that 75% the cause of death is arranged.Medical research is found, the electric bicycle of the riding person that do not helmet, if when the bump head of ground, tend to make brain to cause oedema hemorrhage, the person can make the head that is hit stop relatively slowly and wear the helmet, the sphere of polymerization but can absorb impact in the helmet, can prevent 85% head injuries, and has greatly reduced degree of injury and accident death rate.
At present, ride the electric bicycle person in the process of riding, perhaps select to wear the cycling helmet, perhaps select to wear motorcycle helmet.
The cycling helmet is Shi Pao Droplets one helmet generally, because the Bian soft outer casing although can reduce slight head injury, can not prevent serious cerebral lesion, so the ability of its prevention cephalic injury becomes problem.The new research report that Australia bicycle people right action group delivers recently claims that bicycle helmet can not prevent serious brain damage.Their research conclusion is that 16 result of the tests delivering between 1,987 1998 show that angular acceleration is the main cause that causes brain damage, but most bicycle helmet is designed to resist linear acceleration.During linear acceleration, external force causes skull and accelerates rapidly, and bump is brain tissue the most nearby.And above-mentioned principle is still continued to use in the at present design of the ordinary bicycle standard helmet and test, and namely linear the acceleration is the main cause of brain damage, but ignored the angle rotation.The soft helmet of this bicycle is close to and is hit the cranium face, makes end rotation, and produces strong angular acceleration.Helmet designs person does not consider to reduce angular acceleration, and this is the main cause of brain damage.
And motorcycle helmet no doubt has good shock resistance, high safety, and according to the GB811-1998 standard-required, full helmet is not more than 1600 grams, and half helmet is not more than 1300 grams.Electric bicycle is worn motorcycle helmet if ride, even weight is accomplished the helmet of gram more than 1000, also can cause bicyclist's head and cervical vertebra tired.Moreover motorcycle helmet gas permeability extreme difference can cause sense of discomfort, particularly summer extremely very sultry in the process of moving, if chronic fatigue is ridden, can affect bicyclist's safety; Full helmet formula motorcycle helmet simultaneously, its good seal performance damping is strong, soundproof effect is very good and cause affecting wearer's ear hearing, on the little easily door identification complex road surface near the various sound of vehicle, avoid unnecessary accident to occur.
There are in addition a small amount of electric bicycle bicyclist safe wearing cap or the rock-climbing helmet to substitute the helmet; this also is infeasible; because the standard according to industry security cap both domestic and external and the rock-climbing helmet; safety cap is worn on the head; just protect position, the crown not injured by a crashing object the danger that produces with expedition by the article that fall; thereby local protection capping, can not protect the safety of whole head fully.
