隐藏式门把手是“封门杀手”？奔驰、特斯拉都在用

Core Viewpoint - The article discusses the safety concerns surrounding hidden door handles in electric vehicles, particularly in light of recent accidents, and argues that these designs are not merely cost-cutting measures but serve functional purposes in design and aerodynamics [5][10][30]. Summary by Sections Origin and Current Status of Hidden Door Handles - Hidden door handles have a history dating back to the 1950s, initially seen in high-performance vehicles like the Mercedes-Benz 300SL [7]. - Tesla popularized the use of electric hidden door handles with models like the Model S and Model X, leading to widespread adoption among various automakers [9][12]. Functionality and Cost Analysis - Hidden door handles are designed for aesthetic appeal and improved aerodynamics, not for cost savings, as electric systems are more expensive than traditional mechanical handles [10][12]. - The cost of traditional mechanical handles ranges from 30-50 RMB, while electric systems can cost between 300-600 RMB, and even exceed 1000 RMB in high-end models [12]. Safety Risks of Hidden Door Handles - The main safety concern is whether electric hidden door handles can function after a collision that causes power loss. Electric locks may fail if the battery is dead, while mechanical locks typically do not [16][18]. - Despite concerns, Tesla's vehicles with electric hidden door handles have performed well in crash tests, indicating that they are not inherently more dangerous than traditional handles [16][18]. Innovations and Regulatory Standards - New regulations require that all vehicle doors must have a mechanical release function, which may challenge the current designs of many electric vehicles [24]. - Some manufacturers, like Xiaomi and Aito, are already adapting their designs to comply with these new standards by incorporating mechanical backup systems [26][30]. Future of Hidden Door Handles - The evolution of hidden door handles will continue as technology advances and safety standards are refined, with a focus on balancing innovation and safety [30].
