Helmets and gloves can cushion the impact on the driver's head and hands in an accident. In cold weather, they can also protect against cold and wind. In rainy days, they can avoid operating errors caused by wet and slippery. In addition, other protective equipment can be selected, including hand protection, leg protection, back protection, etc. The driver should try to wear bright clothes or reflective clothing, and remember to wear the coat backwards to keep out the wind and cold, so as not to affect normal operation and cause accidents. Players in the age group of 20 or below approved by the International Ice Federation must wear a full face shield, and its structure should be able to block the passage of ice hockey or ice hockey club blades. Ps (polypropylene ethylene) helmet. The interior of the helmet is polypropylene ethylene, and the exterior is a plastic shell. Bs (engineering plastic) hard plastic shell plus eps (polypropylene ethylene) lining, mostly used for extreme roller skating and fsk and other projects.
Electric vehicle helmet At present, there is no unified quality standard "common helmet shells are made of engineering plastics, glass fiber reinforced plastics, carbon fiber and other materials." Han Kuanbao, vice president of Nanjing Electric Bicycle Industry Association, said that the more protective the materials, the higher the price. A high-quality carbon fiber helmet can cost thousands or even tens of thousands of yuan. In addition to material differences, the coverage area of the helmet also has an important impact on safety. The protective effect of full helmet, but poor air permeability; 3/4 helmet gives consideration to both protection and breathability; Half helmet is easy to wear, but the ability to protect safety is poor; There is also a "lift up helmet" that can completely turn up the chin device, which is convenient to wear and has good protection.
Research shows that the use of helmets can greatly reduce the mortality rate and reduce the injury to people caused by traffic accidents to a minimum. How to choose a suitable helmet? Helmets are divided into; Full helmet, 3/4 helmet, half helmet and cross-country helmet. Of course, different helmets are used for different purposes. Full helmet is a common helmet for racing. It covers the head completely and has high protection, suitable for racing and some motorcycle tours. Some helmets that look suitable in terms of parameters may not be worn exactly, so it is necessary to try them on. Important note: The simpler way to put on the helmet is to put the helmet from the head to the back, rather than directly from the top of the head. The back of your head is a large area that allows your helmet to transition, so it's easier to wear it from head to head and forward rather than downward.
Precautions for purchasing helmets: some of the foam cushioning materials for helmets have low density, which is even worse than the foam cushion for home appliances. It will break with a light hand digging - unqualified. Some materials of the lining are uncomfortable to touch. Pay attention to the selection. Be careful that the small black heart factory uses recycled materials to make helmets. The helmets will break if you drop them gently. They will smell and soften when the sun shines, and may contain some toxic and harmful substances in the garbage during recycling. Because this kind of helmet is super cheap, many people buy it. For safety, we must not be greedy. The main certification standards for motorcycle foreign trade helmets: the United States, Canada, etc., DOT certification Europe, ECE certification.
Try not to use wet paper towels or tissues, as these will cause micro scratches and degrade the mirror. The effect will be better if clean microfiber cloth is used together with cleaning solution. The above 7 points are the mistakes that many riders are prone to make. It seems harmless, but the damage to the helmet is often irreversible. It is the right way to change a little, make the helmet have a longer shelf life, and let it "stand up" at the critical moment. Motorcycle helmet manufacturer Professional production statistics show that China has about 90 million motorcycles and nearly 300 million electric automatic vehicles, but the helmet wearing rate is low. Take Zhejiang as an example, the wearing rate is only about 30%. If it is to be met simultaneously in a short time, the production capacity is doomed to be under pressure. At this time, the law enforcement punishment temporarily "exempts" the electric bicycle, gives it a buffer period, also can realize the demand diversion, lengthens the transition period to slow down the impact of the demand surge on the helmet product market, and also provides time and space for capacity matching.
The fiberglass shell can be made of any fiber reinforced material, including fiberglass, carbon fiber and aromatic polyamide. Different materials are constructed in different order, resulting in thin and hard shells. In these cases, the shell can be made thicker or thinner by increasing or reducing the number of material layers. The composite shell is high-density, which is why cheap helmets are made of peeling polycarbonate plastic. These housings are usually thicker and heavier than composite housings. The shell will usually withstand small impacts, such as falling from the seat when you park, without damaging your protection. Small bumps or scratches will not affect it. Anything more serious than a small bump will cause invisible damage, so you can return your helmet to the factory for inspection before you trust it. Any strong enough impact will end the service life of the helmet.
Motorcycle helmet manufacturers specializing in the production of common helmets are divided into full helmet, three-quarters helmet, half helmet and faceless helmet. Full helmet is a helmet with good protection effect, but poor air permeability. Three fourths of helmets are between full helmets and half helmets, with moderate protection and ventilation. Uncover helmet is a kind of helmet that can choose full helmet and three-quarters helmet mode, and its safety is also very high.
The wind resistance is quite high. It is usually only used on off-road vehicles. The motorcycle team of the famous Dakar Rally will wear this helmet. Motorcyclists' habit of wearing helmets originated from the famous cyclist Snell's death in a motorcycle race in California, USA in 1956. Relevant institutions listed helmet protection as a key research object.
