The motorcycle helmet is a head protection device for motorcycle drivers and passengers. The main purpose of the helmet is to protect the knight's head, prevent or reduce damage and even save the knight's life when being impacted. What material is good for motorcycle helmet? How to choose the size of motorcycle helmet? What brand of motorcycle helmet is good? Come and see what Xiao Bian has prepared Motorcycle helmet manufacturer Go shopping!
Nowadays, motorcycle helmets should be worn when riding a motorcycle, which is for the sake of safety. It is very important to buy a good motorcycle helmet, which can better protect personal safety in case of an accident. Here are some tips for choosing motorcycle helmets.
(1) The inner side of the helmet must be equipped with an anti impact pad. The surface pad material that matches the head is thin mesh lining, which should have the function of absorbing sweat and oil from the head. In addition, the pad shall be provided with a ventilation slot with a depth of more than 10MM to allow air circulation in the helmet.
(2) The jaw strap shall be soft, and the snap fastener and other hard protrusions shall not exceed the external surface by 5mm.
(3) The helmet should be light and comfortable, and its weight should not exceed 2KG.
(4) The helmet shall not be blocked or suffocated, and the vision shall be wide and clear without shielding. The visual angle shall not be less than 105 degrees when stationary.
(5) The sound from all directions can be clearly heard and distinguished when wearing the helmet, and there should be no vibration and other noises during driving.
(6) The helmet shall be equipped with good ventilation and heat preservation devices inside, and shall be dust-proof, insect proof and waterproof.
(7) Helmets should have good reflectivity and thermal radiation resistance, and highlight obvious eye-catching colors.
(8) The lens of helmet goggles is clear and colorless, and its toughness is not easy to break, so as to ensure that the driver's vision is not affected.
(9) The helmet shall be made of glass fiber laminated structure.
In general, the first thing to consider when choosing a helmet is the burden on the neck when wearing the helmet, and feel its weight when the body maintains balance. The balance of the helmet is very important, because the closer the center of gravity of the helmet is to the center of gravity of the head, the less fatigue it is. Therefore, the important thing is not the weight of the helmet itself, but the balance performance of the helmet.
From the perspective of safety, when the helmet is strongly impacted, the soft foam spacer inside the helmet can prevent the impact from hurting the head. Some damaged helmets have three or four collision marks almost at the same place. With regard to the permeability of the helmet, the ventilation device is not installed near the opening of the protective sleeve of the helmet itself, but on the protective sleeve body, mainly to maximize the protective range of the helmet when hit.

Generally speaking, the suitability of helmet can be worn on any head type. However, attention should be paid to the permeability and size of the helmet. When riding with helmets, you should not feel that the helmets tighten your neck and wrap your head tightly, causing poor breathing. At the same time, the size of the helmet should try to choose a suitable helmet that will not move and will not wear the protective sleeve at the bottom of the helmet too much when it is taken off and put on frequently.
Because everyone's head shape is different, consumers need to accurately measure their head shape before buying helmets. Measure the head size, that is, measure the head circumference from the eyebrow bone to the back of the brain. When purchasing a helmet, you need to choose a helmet that is 2~3cm larger than your head circumference, so that you can wear it most comfortably.
What kind of material is good for motorcycle helmet
The quality of helmets -- Part on shell materials of helmets
1. ABS resin materials are common, such as Taiwan's Qimei brand. This is an engineering plastic with strong impact resistance and good dimensional stability. Market price of helmets made of this material: usually the price of full helmets is between 100 and 300.
2. PC+ABS alloy is better than ABS, its strength and toughness are improved a lot, and its low-temperature impact performance is also improved a lot. At present, the domestic Austrian energy alloy materials are widely used in helmets.
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 should be carbon fiber, very strong, very light, high technical content, very expensive!!! (This material can be used as a fishing rod.)
5. PP material can only be used as a toy helmet, and its safety is very poor. Never mind.
