Core Viewpoint - The Ministry of Industry and Information Technology has released a draft for the "Safety Technical Requirements for Automotive Door Handles," which aims to standardize the design of vehicle door handles, potentially eliminating all hidden door handle designs in the market if approved [1]. Group 1: Regulatory Changes - The draft specifies that each car door (excluding the tailgate) must be equipped with a mechanical external handle [1]. - Non-collision side doors must be operable without tools through the external handle [1]. - The external handle must provide a hand operation space of no less than 60×20×25 millimeters in any state [1]. Group 2: Industry Impact - If the draft is finalized, it will mandate the removal of all hidden door handle designs from vehicles on the market [1].
