确保断电、碰撞等险情下车门可打开！工信部出手整顿汽车隐形门把手

Core Viewpoint - The Ministry of Industry and Information Technology (MIIT) of China is soliciting public opinions on the draft of a mandatory national standard for "Automotive Door Handle Safety Technical Requirements," aiming to enhance safety performance and ensure the standard reflects industry needs and technological trends [2] Group 1: Industry Trends - The popularity of hidden door handles in electric vehicles (EVs) is driven by design aesthetics, aerodynamic optimization, and competitive differentiation among automakers [3][4] - Among 14,341 models on the AutoHome platform, 1,578 models feature hidden door handles, with 74% being new energy vehicles, indicating a strong trend towards this design [4] - Hidden door handles can reduce vehicle drag coefficient by 0.01 to 0.03 Cd, which is significant for EVs where every kilometer of range matters [4][5] Group 2: User Experience and Safety Concerns - Despite their aesthetic and aerodynamic advantages, hidden door handles pose safety risks, including failure in extreme weather conditions and during accidents, which can delay rescue efforts [5][6] - Incidents have been reported where electric door handles failed to operate during emergencies, leading to tragic outcomes, highlighting the need for improved safety measures [6][7] - The reliance on electronic control systems for hidden door handles can lead to vulnerabilities in critical situations, contrasting with traditional mechanical handles [7] Group 3: Regulatory Response - The MIIT's new standard focuses on three core areas: mechanical redundancy for emergency access, standardized emergency device visibility, and strength testing for extreme conditions [8] - The standard emphasizes "anti-misoperation" design to prevent accidental activation of door handles during vehicle rollovers, reflecting a proactive approach to safety [8] - The evolution of hidden door handles symbolizes the automotive industry's shift from mechanical products to intelligent terminals, balancing engineering, marketing, and user experience [8]
