As automotive electrification progresses, electric hidden door handles have become increasingly prevalent. Following the pioneering introduction of automatically deploying hidden handles by a certain automaker, the notion of 'hidden handles as a standard feature for premium electric vehicles' has steadily gained traction in the market. Presently, hidden door handles available on the market predominantly fall into two categories: lever-operated and electronically controlled. Lever-operated handles deploy through physical pressure, whereas electronically controlled handles extend automatically through motor-driven mechanisms or touch-sensitive unlocking. Nevertheless, hidden door handles have also brought to light several issues, including failure to deploy due to freezing in winter and inability to open after a collision owing to power failure. In light of these concerns, the Ministry of Industry and Information Technology has issued the 'Safety Technical Requirements for Automotive Door Handles (Draft for Comment)', explicitly mandating that exterior door handles on vehicles should steer clear of fully concealed designs. Additionally, each door must be equipped with an exterior door handle incorporating a mechanical release mechanism to ensure seamless door opening in emergency scenarios.
