As an important head protective gear, the electric bicycle helmet can reduce the injury of collision, puncture, and rolling in the head, and reduce the injury and death in the accident. The quality of the helmet is directly related to the personal safety of 300 million electric bicycle driving passengers. With the promotion of various local supervision, people wearing a helmet gradually get more.

However, more than 80% of the electric bicycle occupants in the market are composed of housings + sprinkle + wearing device, there is a great security risk. Which structured electric bicycle helmet is safer? Recently, the Nanjing City Consumers Association bought 50 models of products through the line, and the comparative trial was found. Since the electric bicycle helmet has no mandatory standards, the "three no" in the helmet product is very serious.

The helmet price gap is large, and only half of the e-commerce platform is only

In May 2020, the Ministry of Public Security's "One Helmet Belt" policy is implemented, the helmet market is very hot, leading to a sharp rise in the helmet unit, to the sampling, the helmet heat has not been resolved, and the overall market price is much higher than in previous years. As of late June 2021, Taobao data statistics, 30% of users like helmets prices less than 25 yuan, 60% of users like the helmet price between 25-85 yuan, more than 9% intervals 85-420 yuan between.

This sample, no electric bicycle helmet with 25 yuan and more than 420 yuan, the lowest price is 35 yuan, the highest price is 222.1 yuan; no less than 85 yuan of helmet 33 batches, higher than the helmet of 85 yuan.

The price of underline is much lower than that of the e-commerce platform electric bicycle helmet price, only 53.4% of the e-commerce platform. Young people often choose the e-commerce platform to buy, more concerned about the shape of the product, whether the brand is well-known, and is not sensitive to the price. The online consumer group is generally the middle-aged and elderly people and the working family, more concerned about the price, and paying 100 yuan to buy helmets. The consumer group is different, but the price of the helmet is directly reflected in the structure and material of the product.

Production enterprises have lowered the test parameters, only 3 of the 50 helmets won five-star rating

The industry is generally believed that the product is equivalent to a low-profile motorcycle occupant helmet, close to the requirements of the B-class half of GB811-2010. Therefore, many production enterprises refer to Class B half helmets to develop corporate standards, which greatly down-regulate parameters, and most of the collision performance indicators are not set, many of the helmets that meet the corporate standards can not have the corresponding safety protection.

In view of this, in order to determine the safety bottom line, the electric bicycle across the country, the helmet association has issued a group standard, of which the Yueqing group is relatively low, Shenzhen, Jiangsu group mainly put forward the requirements of the local helmet, Zhejiang is The helmet production base, focusing on the quality of the helmet in the production field.

This comparative trial is mainly based on the Jiangsu Electric Vehicle Industry Association Group Standard T / JSEBA001-2020 "Electric Bicycle Helmet Technology Requirements and Testing Specification", Yueqing Helmet Industry Association Group Standard T / TXB001-2019 "Electric Bicycle Helmet", In response to the quality of the helmet, the helmet wearing device stability, the helmet wearing device strength, the helmet absorption collision energy performance (low temperature), helmet is tested.

In terms of wearing device stability, the comparative trial has a total of 29 products, and 19 products have a buckle break, fall off and other phenomena in the wearing device strength test, and two projects of 14 products have problems. Only two items in these two products have also met the requirements of Jiangsu group standard and Yueqing group.

In this comparative trial, there were 30 batches of steel cone penetrating housing contact head types in the test, and a huge cracks of more than 100 mm length occurred in 1 batch trial.

From the product structure, 33 batches of helmets without buffer layers have occurred seriously rupture, acceleration peak exceeding standards, and 9 batches of the Jiangsu group test in 17 batches of helmets.

According to the star evaluation rules, the 50-batch product rating results of this sample check are as follows: 3 products have 5 star evaluation, 1 product is 4 star evaluation, 2 products receive 3 star evaluation, 4 Products have been given 2 star evaluation, and 40 products have been evaluated.

The larger the ventilation hole, the more the head is exposed to the outside.

The results of this comparative trial have found that many manufacturers have no standard, without standard, without standard, without standard, without standard, there is no bottom line. The Nanjing City Consumers Association recommends that consumers buy helmets with buffering layers, do not buy a helmet with only sprouts.

When you use it, you will feel the stability of the helmet, and some parts are significantly highlighted from products other than helmets. It is recommended not to buy. Up and down mobile goggles and other devices, it must be flexible and reliable, and the goggles should have no cracks, scratched, colorless transparency. The lace should have sufficient width, which is generally better than the width of the adult thumb. Check if the lock is fastened, unopened.

Trying to clean the helmet to clean the packaging, the correct way is to bring the helmet back to the upper and lower sets of the head, feel that the head is comfortable, the adjustment is tight, and the helmet should not sway when the head is shocked. Then tap the housing of the helmet and feel that the earthquake is suitable. The larger the helmet, the more the wind is exposed, the more the head is exposed, and the protection performance will be relatively low, so the housing can be selected and the helmet of the housing and the buffer layer is misaligned or obliquely open.

In addition, the helmet has life, exceeding service life protection, due to aging, due to aging. Plastic helmets should generally be more than 3 years, carbon fiber helmets are generally not more than 5 years. Try to be placed in a cool and ventilated position during daily storage, avoid direct sunlight and exposure to acid, alkali, organic solvent, so as not to reduce the protective properties of the housing.

Calling on national standards, grasping the development of the co-management

In response to no fixed standard, it is difficult to standardize, Nanjing Consumers Association calls for the revision of GB811 "Motorcycle, Electric Bicycle Helmet" standard revision process, and sclecting the safety bottom line for electric bicycle helmets as soon as possible. Encourage advanced helmet companies to participate in standard revisions, neither a taste of security, can not blindly catering to the market, reducing the most basic security.

The electric bicycle helmet is a consumable product, and its consumer group has a significant part of the low-income group and is very sensitive to the helmet prices. If you need more than 100 yuan to buy a qualified helmet, you will seriously deviate from the market demand, then the standard cannot be effectively implemented. In the investigation of market and production enterprises in 2020, the cost of the helmets of the minimum safety requirements can be controlled around 30 yuan, so that the market price is 560 yuan of helmet consumers are easily accepted.

The market supervision department organized the main line of the helmet product. According to the helmet product situation and the information currently learned, the requirements of the electric bicycle helmet will be higher than that of the Yueqing group after the revision of the GB811, and is close to the standard requirements of Shenzhen, Zhejiang, Jiangsu and other groups. In the circulation, the e-commerce platform refers to the Yueqing group standard to define the quality bottom line. Three unfilled products are severely investigated, and merchants selling three unfilled products from strict punishment, and urge the production enterprises to recall.

The major producers should actively cooperate, formulate clear recall, local administrative supervision departments supervise and implement, and strengthen the analysis. The quality inspection and technical institution actively contacts the supervision department at all levels to formulate reasonable scientific supervision, monitoring programs to help administrative departments understand, master local helmets, real-time risk warning.

The traffic management department strengthens the inspection of wearing helmets in traffic management, handling the unwind helmet according to law, watching the warning education of the helmet or helmet, on the spot, and urges the police to drive the bicycle.

The standardized department organizes the overturning of electric bicycle helmets, and the corporate standards that do not set absorbed collision energy projects are required to rectify, and the partial parameters set too little or unreasonable to rectify opinions and urge rectification.

All local associations encourage members to take the initiative to close to Shenzhen, Zhejiang, Jiangsu and other groups. For membership companies to strengthen standard technical training, organize member companies to learn advanced helmet companies, strengthen intra-industry technology exchanges; provide training for helmet knowledge, to avoid new companies, resulting in quality problems due to products.
