This invention discloses a car safety latch, belonging to the field of automotive lock technology. Its structure includes six forms: retractable safety latch, sliding safety latch, pneumatic safety latch, hydraulic safety latch, electric safety latch, and manual safety latch. The structure comprises a battery, wires, a gas generator, a cylinder chamber, a hammer, a latch chamber, a slide rod, a button, a fork-type latch, and a positive pressure spring. It is fixedly installed inside the car door frame. The straight locking pin of the fork-type latch protrudes outside the door frame, opposite the lock body on the door. In the event of a collision, the power unit is triggered by a collision sensor, manual pressing of the button, or the car's electronic control unit, causing the fork-type latch to move, disengaging the latch tongue from the straight locking pin of the safety latch, thereby opening the car door.
