工信部国标新规：车门把手必须“留保命后手”！

Core Viewpoint - A new mandatory national standard for truck door handles, GB 48001-2026, has been approved and will take effect on January 1, 2027, addressing safety concerns in the context of vehicle electrification and the reliability of door handles under extreme conditions [1][8]. Summary by Sections Standard Overview - The standard, organized by the Ministry of Industry and Information Technology, aims to enhance the safety design level of automotive door handles, particularly in light of the evolving electrification technology [9][10]. Key Requirements - External Handles: Each door (excluding the tailgate) must have a mechanical release external handle; it should be operable without tools after an accident or battery thermal runaway, with a strength of at least 500N [29][30]. - Internal Handles: Each door must have at least one mechanical release internal handle that is unobstructed and visible, located within 300mm of the door edge, and must include permanent markings and instructions [29][30]. - Safety Redundancy: In the event of irreversible constraints (like airbags deploying) or battery thermal runaway, the mechanical release external handle must still allow the door to be opened; collision must automatically disengage the electromagnetic lock, with backup power for the door lock lasting at least 3 minutes [29][30]. Implementation and Impact - The standard categorizes trucks based on weight, with N1 class trucks (≤3.5 tons) being subject to mandatory compliance, while N2 and N3 class trucks will follow as a reference, effectively setting a new industry benchmark [28][34]. - The standard does not ban hidden door handles but requires them to have mechanical redundancy; fully electronic hidden handles without mechanical backup will be phased out [30][31]. - The traditional fuel-powered heavy truck sector will continue to favor exposed mechanical handles due to their reliability and cost-effectiveness, while the trend towards electric and low-drag designs will push for compliant hidden handles with integrated mechanical redundancy [31][32]. - This standard is expected to shift the industry focus from solely prioritizing low drag to balancing safety and operational efficiency, accelerating the upgrade of supply chains towards integrated electromechanical solutions [32].
