[0005] The device makes it safer for passengers to escape by setting up protective parts. However, the device has certain defects, that is, when escaping, passengers need to move to the top of the main body through the life-saving hatch. Since the life-saving hatch is set at the top of the main body, and the interior height of the car is generally about 2.2 meters, and there is no auxiliary mechanism in the main car, it is difficult for passengers to climb to the top of the main body, reducing its practicality.
