Electric vehicle helmet Precautions for purchase

1. When choosing an electric vehicle helmet, you should consider the burden on the neck when wearing the helmet, and feel its weight when balancing the body. 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 will be. Therefore, what matters is not the weight of the helmet itself, but the balance of the helmet.

2. Because everyone's head shape is different, consumers need to accurately measure their head shape before purchasing electric vehicle helmets. Measure the head shape, that is, measure the head circumference from the eyebrow bone to the back of the head. When purchasing a helmet, you need to choose a helmet 2~3cm larger than the head circumference, so that you can wear it comfortably.

3. The interior of the electric vehicle helmet must be equipped with an anti-collision lining. The surface lining material that fits the head is a thin mesh lining, which should have the function of absorbing sweat and grease from the head. In addition, there should be a ventilation slot with a depth of more than 10MM on the pad to allow air to circulate in the helmet.

4. The chin strap should be soft, and the distance between the hard protrusions such as buckles and the outer surface should not exceed 5MM.

5. The helmet of electric vehicle shall be light and comfortable to wear, and the weight of the helmet shall not exceed 2KG.

6. The electric vehicle helmet is not blocked, not stuffy, and the vision is clear and unobstructed. The static viewing angle shall not be less than 105 degrees. In this way, when wearing the helmet, you can clearly hear and distinguish the sound from all directions, and there should be no vibration and other noise during driving.

7. The helmet of electric vehicle shall be equipped with good ventilation and thermal insulation devices, and shall be dust-proof, insect proof and waterproof.
