The whole country will carry out the "One Helmet One Belt" security guard action, and the Yuhuatai District Market Supervision Administration of Nanjing attaches great importance to it and immediately carries out Electric vehicle helmet Supervision and inspection of quality and price. In the process of inspection, it was found that some businesses had illegal behaviors such as selling three no helmets and not clearly marking the price, and they were ordered to correct, and a "price policy warning letter" was issued to them.

There are many kinds of electric vehicle helmets, and there is no unified national standard at present. So how should consumers choose helmets? Through comparison, the law enforcement personnel suggested that the safety, air permeability, comfort, vision and other aspects should be focused on. The inner side of the helmet must be equipped with an anti impact pad, which is compact, and it is better not to drop slag or leave the pit when pressing by hand. The surface pad material matching the head is thin mesh lining, which should have the function of absorbing sweat and oil from the head. In addition, a ventilation slot with a depth of more than 10 mm shall be provided on the pad to allow air circulation in the helmet. The jaw belt shall be soft, and the snap fastener and other hard protrusions shall not exceed the external surface by 5mm.

"When wearing a helmet, you should feel light and comfortable, and the weight of the helmet should not exceed 2 kg. It should not be blocked, stuffy, open and clear, without shielding, and the visual angle should not be less than 105 degrees under static state." The law enforcement officer told reporters that if the helmet is equipped with goggles, the goggles should have a certain toughness, and the surface should not have cracks, scratches and other visual defects.

Here, the law enforcement personnel also remind the operators that they should select regular manufacturers and suppliers when purchasing goods, fulfill the purchase inspection obligations, properly keep the business license, purchase receipts and helmet test reports of the manufacturers or upstream suppliers, and strictly control the quality of helmets. In the process of selling helmets, the price shall be clearly marked, and shall not exceed the marked price for sales. In the case of no substantial increase in purchase costs, the price shall not be raised, and the sales price shall not be raised significantly.

At the same time, it is also necessary to remind consumers not to covet cheap helmets, but to purchase brands with good reputation through formal channels. When purchasing, pay attention to the identification information on the helmet and its outer package, such as whether there is a factory name and address, production date and quality certificate, and do not buy three no products. In addition, it is necessary to keep the invoices and vouchers when purchasing, so as to protect rights in case of problems later.
