The invention belongs to the technical field of emergency door opening of automobile doors, and particularly relates to an automatic door unlocking mechanism after automobile collision. The inertia switch is used for sensing impact acceleration and controlling on-off of an ignition circuit of the explosive bolt; an explosive bolt is used as a main connecting piece of the door lock hook and the vehicle door frame structure; a retractor structure with an automatic locking function and a fabric belt are used as auxiliary connecting pieces of the door lock hook and the vehicle door frame structure; an automobile power supply is used as a main power supply for explosive bolt ignition; a capacitor is used as an auxiliary power supply for explosive bolt ignition; an automobile power supply is used as a charging power supply of the capacitor. When the inertia switch senses that the impact acceleration peak value is larger than the threshold value, the inertia switch is switched on, the current discharged by the automobile power supply or the capacitor passes through the explosive bolt circuit, the explosive bolt detonating structure is disconnected, and the door lock hook and the automobile door frame are disconnected; when the vehicle door is opened to drive the door lock hook to move too fast, the retractor can automatically lock the fabric belt, and the vehicle door is prevented from being opened rapidly. Compared with an existing vehicle door collision automatic unlocking mechanism, the method has the advantages of being high in reliability, low in refitting cost, high in survivability and the like.
本发明属于汽车车门应急开门技术领域，具体涉及车辆碰撞后的车门自动解锁机构。本发明使用惯性开关感受撞击加速度，控制爆炸螺栓点火电路的通断；使用爆炸螺栓作为门锁挂钩与车门框结构的主连接件；使用带自动锁紧功能的卷收器结构和织物带作为门锁挂钩与车门框结构的辅连接件；使用汽车电源作为爆炸螺栓点火的主电源；使用电容作为爆炸螺栓点火的辅电源；使用汽车电源作为电容的充电电源。当惯性开关感受到撞击加速度峰值大于阈值时，惯性开关接通，汽车电源或电容放电的电流通过爆炸螺栓电路，爆炸螺栓起爆结构断开，断开门锁挂钩与车门框的连接；当车门打开带动门锁挂钩的运动速度过大时，卷收器会自动锁紧织物带，阻止车门急速打开。相比现有车门碰撞自动解锁机构，本方法具有可靠性高、加改装成本低、生存能力强等优点。
