[0002] With the continued development of the global economy and the continuous improvement of people's living standards, the number of cars, an indispensable means of transportation in modern life, has shown a steady growth year by year. However, this is accompanied by a year-on-year increase in the number of car accidents, posing a serious challenge to road traffic safety.

[0003] In recent years, with the rapid development of automotive electronics, the level of vehicle electrification has been increasing, a trend particularly evident in door lock systems. Traditional mechanical door locking devices are being gradually replaced by advanced motor control systems. This transformation not only enhances vehicle intelligence but also provides users with a more convenient operating experience. However, while the introduction of motor control systems improves the automation level of door locks, it also introduces new problems: motor failure or vehicle power outages can prevent doors from opening properly.

[0004] Especially in serious accidents like collisions, which often damage the vehicle's electrical system, interrupting the 12V low-voltage power supply can cause the electronic locking system to lose power and become unable to respond to control signals. Collisions can also cause door deformation, further impacting the accuracy and reliability of motor control, preventing the door from opening smoothly at critical moments. This reduces vehicle safety and hinders vehicle quality. Utility Model Content
