Electric vehicle helmet Insufficient strength and performance of wearing device

The strength performance of the electric vehicle helmet wearing device refers to the consideration of the strength of the key parts of the helmet, which mainly refers to whether the strap, adjusting device and buckle can be firmly worn on the head under the impact pressure. Unqualified products have broken belts and joints during the test, and such helmets cannot protect the head in case of accidents.

Electric vehicle helmet cannot absorb collision

The ability of electric vehicle helmets to absorb collision is also related to our riding safety. In order to simulate the real environment to a large extent, the helmet was pretreated with high temperature, low temperature and immersion. In the experiment, it was found that the quality of some helmets was greatly reduced after immersion in water, and they were broken into two pieces under impact. This also means that these helmets will not play a protective role in a rainy environment.

The stability of wearing device is unqualified

In the experiment, it was also found that the stability of the helmet wearing device was not qualified, and the helmet was easy to fall off from the head. In the process of riding, once the head moves too much or the head is scratched, the helmet will fall off. It will fall off and cannot be protected.
