Electric vehicle helmet What is the necessity of selection
1. Service life: when purchasing electric vehicle helmets, it is necessary to confirm whether there is relevant certification. In addition, remember to pay attention to the service life of electric vehicle helmets, which is generally 3-5 years (the service life of helmets made of different materials is also different). If the electric vehicle helmet is impacted by external force, although the appearance is not damaged, the internal buffer material has been deformed and cannot provide effective protection, please do not use it again.
2. Air permeability: the helmet of electric vehicle will come into the market only after it has been tested in the actual wind tunnel for practical use. When the jaw opening is opened, the mirror fog can be successfully taken away.
3. Lenses: High quality lenses are designed safely, not only not fragile, but also unbreakable. In other words, no matter how twisted, bent, or hit, the crack will not break.
4. Lining: Each electric vehicle helmet pursues comfortable lining, which usually includes the main pad above the head and ear pads on both sides of the ear. A good lining not only helps the head closely fit with the helmet body of the electric vehicle, but also has the effect of shock absorption. Most high-quality electric vehicle helmets can be removed and cleaned if their linings are dirty, and they can be purchased and replaced with different thicknesses, so as to realize the electric vehicle helmets that really fit your face.
5. Safety buckles: When wearing electric vehicle helmets, do not be careless or lazy, and do not fasten the safety buckles of the safety belt. High quality electric vehicle helmet belt has passed strict tension test. The double D-ring fixing buckle is a relatively safe safety buckle at present. Only by fastening it can we prevent the helmet of electric vehicle from flying out in case of an accident.
6. Size: When purchasing a helmet, first measure the size of the head, and then get the size of the end z by measuring the area above the eyebrows and the wider area of the head. New electric car helmets are usually a little tight, and it is normal to have faces and cheeks. If there is obvious pressure on the temples and top of the head, it is too small. Wearing a smaller electric helmet for a long time will cause headache. Shake your head from side to side so that the helmet of the electric vehicle does not feel obvious shaking.
