You may not know, but most of the Electric vehicle helmet All of them are substandard and inferior products that can not play a role in protection. Many electric car businesses do promotions to buy electric cars and give away helmets. If you give away these electric car helmets, you must not want them!

At present, the price of electric vehicle helmets on the market is very different. There are dozens of helmets and hundreds of helmets. I don't know which kind of quality is more guaranteed. If you think it is expensive, it is not certain. Is it possible to buy a "ladle helmet" for 10 yuan to show cost performance? That would be a big mistake! It's neither cheap nor expensive, so how to choose an electric helmet? What should I choose when buying an electric helmet? How much can I buy the right one? What kind of electric vehicle helmet can ensure safety? What performance should we pay attention to when shopping?

These electric car helmets are dangerous

1. General plastic for housing

Generally, the primary material for helmets is ABS resin, which costs about 100-300 yuan. This material has strong impact resistance and is not prone to serious deformation. There are also better helmets made of PC+ABS alloy, about 300-1000 yuan. In case of an accident and being hit, they can absorb shock, with good strength and durability, so as to maintain the head. From the material point of view, there are also helmets made of glass fiber reinforced plastics and carbon fiber materials, which cost more than 1000 yuan, have good ventilation, high safety, strong hardness and impact resistance, and are not easily deformed when being squeezed. Helmets made of general PP materials have no protection at all. Some of them have poor endurance and are too fragile. They will break when they are knocked lightly. There is also a helmet made of a plastic called polypropylene. Although it is cheap, it has low strength and poor quality.

Even some helmets are too soft and easy to deform, which is a pit when you press them with your fingers. How can you maintain your head? You can't ask for a free gift.

The better the quality of the helmet, the better the protective effect on the head.

2. Buffer foam is too thin

The helmet shell has been jerry built, and the buffer foam in the helmet should be reduced from three thicknesses to one and a half. Once a risk situation occurs, the impact force cannot be blocked, and the head will be injured by this strong impact force, ranging from skin damage and concussion to life danger.

Therefore, the helmet with a thin layer of buffer foam is definitely not good. Safety helmets used on the construction site should not be worn for cycling, and the protection is limited.

3. The coverage area is too small

Although the helmet only protects your head, whether it completely protects your head depends on its coverage area. Helmets are divided into full helmets, open helmets, half helmets and other types, which are generally used for riding motorcycles. There is no national standard for "electric vehicle helmets". The larger the coverage area is, the higher the safety is, but it is relatively stuffy, and the permeability is not so good.

Some electric vehicle helmets are simple in shape, commonly known as "ladle helmets", and cover a small area. They are used for checking, but in fact have no protective effect. If you want to be responsible for your own life safety, don't buy them!

4. Incomplete label mark

Some electric vehicle helmets on sale have incomplete labels and no production license required by any national production regulations,

The formally produced helmets not only have reasonable requirements for the function of absorbing collision energy and covering area, but also have certain goals for the goggles of helmet protection in terms of transmittance, refractive function, intensity, etc. If you buy a production license, it is illegal production. Let's not pay for it!

5. Three no products

It should also be noted that helmets without any factory name, address or date of manufacture, and such helmets generally do not have any identification information, are "three no products". As we all know, without quality assurance, we can't protect ourselves. It may also affect our riding conditions. For example, the shape of helmet is not standard, the heavy weight of materials increases the head weight, and the comfort is poor.

6. No 3C certification mark

No matter what kind of helmet it is, the 3C mark must be recognized:
