One-piece Electric vehicle helmet It means that the electric vehicle helmet manufacturer puts the blistered PC shell and foam data into the molding machine to form the product at one time. The whole helmet is a whole, with strong resistance and strength. It is also better for head protection. In case of danger, the helmet will deform and crack, which can effectively dissolve the force of the head hitting the ground and protect the head. The non integrated molding of electric vehicle helmet means that the foam is molded first, and then the blister PC or PVC blister shell is covered on the foam.
1. Look:
How to see it? Let's take the electric vehicle helmet in our hand and carefully observe the place where there are holes in the helmet and the place where the edge of the helmet is. You can easily find that the fake one-piece electric vehicle helmet, due to the manufacturer's level of technology, makes these places have small spaces. Almost every hole has this phenomenon. But this situation will not happen to the truly integrated electric vehicle helmet. Because it injects EPS directly into the cap shell, just as we pour concrete and hit beams, there is no space between the formwork and concrete, which is a perfect combination.
2. Touch:
How and where should I touch it? Still touch the places we just mentioned, that is, use our most sensitive fingers to touch these places up and down, left and right, and you will feel that the fake one-piece electric helmet will scratch your hands very much, because it is not well combined. The one-piece electric vehicle helmet is perfectly integrated, and there is no space for it, so it will not scratch our hands naturally.
3. Listen:
How to listen? It is to use one hand to hold the electric vehicle helmet, and the other hand to strike the electric vehicle helmet everywhere. At this time, you will hear the sound just like the sound that our things are empty and announced, or the sound that is about to be broken but not broken. The sound is unclear, but muddy. Then the electric vehicle helmet must be a fake one. And the sound announced when the really integrated electric car helmet hits is like the sound and image of the solid wood furniture in our house when it hits.
