When the vehicle encounters an unexpected emergency, it is impossible for all occupants to evacuate safely from the narrow door in an orderly manner. Although the horizontal sliding window can be opened, the opening area is less than half of the overall area of ​​the window. It is not easy to escape from the opened part. Although the closed window is equipped with an escape hammer, it is easy to lose, and its use effect cannot be known without a destructive test, and the inspection cost is relatively high. At the same time, new glass needs to be reinstalled after the window is damaged. frame

[0003] In addition, the design of the bus includes an escape channel, but the current standard only considers the overturning of the passenger car, and the escape openings are arranged on the roof and floor of the vehicle. However, if a fire occurs on the vehicle, the fire will spread rapidly. In some cases, the escape hatches on the roof and floor cannot function at all, and the exit area is not enough to ensure the rapid evacuation of the occupants.
