For our own safety, when driving electric vehicles or motorcycles, Electric vehicle helmet The manufacturer still suggests that it is better to actively wear electric vehicle helmets, and some places will start to check whether to wear helmets.
If you don't know much, and usually ride a battery car to work, buy a dish or something, you don't need to know so many professional helmets. You only need to know three kinds of helmets: half helmet, full helmet, and 3/4 helmet.
Helmet category:
Full helmet: completely wrap the head, lack of ventilation, relatively stuffy
Uncover helmet: a full helmet that can turn the chin to the head
3/4 helmet: full helmet without protection at chin
Half helmet: no protection for chin and back of head
According to the helmet shell material, it can be divided into several types:
1. Common is the resin material of ABS, which is a thermoplastic polymer material with high strength, good toughness and easy processing.
2. PC+ABS alloy is better than ABS. It is generally referred to as ABS engineering plastics in the market. The strength and toughness of PC+ABS are much higher than ABS itself, and the low-temperature impact performance is also improved.
3. FRP is better than ABS, lighter and stronger, but it is also more difficult to make. The output is low, so it is much more expensive than ABS.
4. At present, the best one should be carbon fiber, which is very strong, light and highly technical.
5. PP material can only be used as toy helmet, with poor safety.
Generally, I often ride a short distance, but ABS is good. If you need a better one, you can consider fiberglass and carbon fiber. In addition to the shell material, pay attention to the inner shell material. It is a kind of cushion material inside the helmet. Its main function is to resist external impact and effectively cushion external forces. Most of them are EPS materials. If there is no such material, it is relatively unsafe. In particular, most helmets in summer do not have them, but there will be compartments to cushion them.
When shopping, you should pay attention to the parameters. If you are not clear, you can ask the customer service.
In addition, it is better to buy helmets that have passed the quality certification, but many helmet certification are aimed at motorcycle helmets, and electric vehicle helmets are not good enough in this regard.
Here are some common motorcycle helmet certifications:
1. The U.S. DOT standard: the abbreviation of the U.S. Department of Transportation, is a mandatory requirement of the U.S. government for helmets sold in the country.
2. European ECE standard: abbreviation of the Economic Commission for Europe, and the full name of the standard is ECE-2205.
3. American SNELL standard: In order to commemorate the unfortunate death of a comrade named SNELL, it is an independent safety testing agency and has formulated a set of safety standards for sports protective equipment known as the world's most professional.
4. UK SHARP certification, Safety Helmet Assessment and Rating Programme.
5. Japan's SG and JIS certification: The SG (Safety Goods) logo is formulated by the Consumer Product Safety Association (CPSA) in accordance with the Consumer Product Safety Law, and JIS is a Japanese industrial standard.
6. Australian AS/NZ1698 certification: the joint standard of Australia and New Zealand.
7. CSA certification in Canada: Canadian Standards Association
8. Chinese GB standard: a professional standard in China, although comprehensive, many enterprises have not implemented it
China's standards are relatively less professional in the certification, and many helmet manufacturers do not follow the cn standards. In this regard, our country still needs to improve.
The common certification standard of Chinese helmets on the market is CCC (3C) certification. Generally, these helmets are of relatively good quality. When you buy them, first check the details of the goods. If not, you can ask the customer service whether these models support 3C certification. The customer service will tell you.
However, we don't have to worry too much about certification. After all, we are not so professional.
If there is no certification, it mainly depends on the material of the helmet. Material contrast has been mentioned above.
Most of the recommended materials are made of ABS, but there are also better ones.
Summer helmets generally do not support EPS middle layer materials. Other helmets are generally available. You can check the product details. Or ask customer service.
Well, the helmet materials and classifications have been introduced. Here are some electric vehicle helmet manufacturers with good comments on the website. You can make some choices.
