Helmet as an important vehicle head protection, in the event of an accident, can greatly reduce the casualties in the accident, its product quality is directly related to personal safety. This year's March 15 party focused on poor quality riding helmets, selected the hot-selling electric bicycle helmets on the market, in the absorption of collision energy, penetration resistance, wearing devices, goggles wear resistance of these four performance tests, found that the quality of many helmets on the market is not up to standard. So, how to choose a suitable and safe helmet? To this end, the big Wan news reporter for this visit.Test: One helmet was almost split in halfAbsorbing collision energy performance test is the core safety index of electric bicycle helmet. In this year's March 15 party, 315 Product Safety Laboratory, together with the Jiangsu Provincial Consumer Rights and Interests Protection Committee, selected the hot-selling electric bicycle helmets on the market for testing.In this test, the performance tester will wear the helmet on the head mold and pull it up to a height of 1.6 meters to release it, simulating the collision between the head and the ground when the rider falls down. A red helmet cracked in response, creating a crack more than 20 centimeters long that failed to achieve any cushioning effect and failed the test. A pink helmet with a foam cushion, the shell and the cushion cracked at the same time.In the penetration resistance test, the tester will pull the steel bar head to a height of 1 meter to release, simulate the helmet encountered sharp objects, the wearer's head protection ability, eight helmets do not meet the requirements of the new national standard, and some are almost split in half. When testing the helmet wearing device of the electric bicycle, it simulated whether the helmet could be fixed on the wearer's head for continuous protection in the event of an accident, and a total of 16 models did not meet the requirements of the new national standard.Purchase: Some people pay most attention to the appearance level of helmetsAs a consumer of electric bicycle helmets, what is the main concern when purchasing? "Our young people's first choice may be more beauty, followed by price, and pay less attention to safety."

From the homepage of the product performance introduction, you can see that the helmet is made of polypropylene, engineering plastic, light material, the main "riding without bondage", weight of about 487g. The product comes in a variety of colors and can be selected with different appearance patterns. The reporter noticed that under the purchase comment area of the helmet, there were consumer comments "the helmet is relatively lightweight, in addition to looking good, the other is not good, the quality is bad."Another safety helmet marked with the new national standard CCC certification, the price is about 130 yuan, the introduction of authoritative testing and identification, the use of national 3C quality standard materials, the main safety protection, there are EPS helmet buffer layer material, PC (transparent mirror transmission 90%) enhanced HD lens, 709ABS (high strength impact resistance) solid helmet, Knob head girth regulator, weight 705g, monthly sales 6000+. One buyer commented that "the helmet is good in both workmanship and quality, looks good, has 3C certification, and is excellent value for money."It seems that although some buyers focus on different points when purchasing helmets, the quality requirements are the same.Industry: The new national standard will be formally implemented this yearHelmets are considered a rider's last line of defense in the event of danger. Dawan news reporter interview learned that the current market electric bicycle helmet is the main implementation of GB 811-2010 "motorcycle occupant helmet" and GB 24429-2009 "sports helmet bicycle, skateboard, roller skating helmet safety requirements and test methods" these two national standards.The market is growing rapidly, the demand for a helmet is increasing, and the electric bicycle helmet industry is also in urgent need of regulation. The reporter was informed that the mandatory national standard GB811-2022 for motorcycle and electric bicycle occupant helmets (hereinafter referred to as the new national standard) has been released and will be implemented on July 1, 2023. It is worth noting that on the basis of the original motorcycle occupant helmet, the new national standard includes the electric bicycle occupant helmet into the standard range, and makes clear provisions on the product structure, the stability of the fixed device, the strength of the wearing device, and the performance of absorbing collision energy.The new national standard is clear, motorcycle, electric bicycle occupant helmets are divided into categories A and B according to the applicable objects, class A is the motorcycle occupant helmet, suitable for the motorcycle occupant and the electric bicycle occupant, Class B is the electric bicycle occupant helmet, only applicable to the electric bicycle occupant. In terms of helmet shape, full helmet, 3/4 half helmet and 1/2 half helmet are suitable for electric bicycle occupants. In terms of structural composition, the new national standard stipulates that the helmet of an electric bicycle member must have a buffer layer.Shopping guideOne look, two smells, three presses, four wears, five questionsSo, how to scientifically buy a helmet, so that the safety helmet truly guards the "head safety"? On March 15, the market supervision and administration department of Guangdong Province issued a consumption warning for electric bicycle helmets.The first thing to look at is whether the product has a standardized Chinese logo, including the standardized factory name, factory address, product name, implementation standards, conformity marks, etc., whether the product has a foam material buffer layer, and do not buy helmets without foam material buffer layer. Do not buy helmets with no manufacturer name or non-standard name, no implementation standards, and no product certification;The second important smell, smell the helmet with the nose whether there is a pungent smell, choose odorless or odorless products;The third is to press, press the foam material buffer layer of the helmet slightly hard with the hand, choose the buffer layer to feel dense or have a slight rebound, no pits, no slag products;Fourth to wear, try to wear a helmet, helmet and head fit, wear comfortable, if equipped with goggles, choose a transparent lens with better light transmission performance;Fifth, the protective performance of different helmet types is not the same. The current motorcycle helmet is suitable for electric bicycle occupants, and when purchasing motorcycle occupant helmet products, it is necessary to buy products with 3C certification mark. After the implementation of the new national standard, Class B helmets are only applicable to electric bicycle occupants, and Class A helmets are applicable to both motorcycle occupants and electric bicycle occupants.
