The surface of the carriage 23 at one end facing away from the adjacent compartment 23 is provided with an escape door 24 that can be opened and closed. In other words, at least one of the two compartments 23 located at both ends of the vehicle body 22 is provided with an escape door 24. It can also be said that the escape door 24 is disposed on the compartment 23 of the vehicle body 22 at least one end in the longitudinal direction of the rail 10, and specifically, the escape door 24 is disposed on the first end surface of the compartment 23 of the at least one end, One end face is away from the surface of the adjacent car. The escape door 24 has a first end 31 and a second end 32, the first end 31 of the escape door 24 being pivotally mounted on the corresponding compartment 23, the escape door 24 being tilted relative to the horizontal when opened, and the second of the escape door 24 The end 32 slopes downwardly and projects into the escape channel 11. Thus, when an emergency situation occurs, the rail vehicle 20 is actively or passively parked, the escape door 24 is opened and the lower end projects into the escape passage 11, and the passengers in the carriage 23 can slide down to the escape passage 11 through the escape door 24, thereby evacuating from the escape passage 11.

Thereby, the escape door 24 is switched from the closed state to the open state by flipping down. The escape door 24 adopts a flip structure, and the passengers in the vehicle can be quickly opened by simple operation, thereby effectively improving the efficiency of escape.

Advantageously, the inner surface of the escape door 24 is provided with a slide to facilitate the passenger to slide on the slide to the escape passage 11. It can be understood here that the inner surface of the escape door 24 refers to the surface facing the interior of the vehicle when the escape door 24 is closed.

In still other specific embodiments of the present disclosure, as shown in FIGS. 67 and 68, the vehicle body 22 includes a plurality of compartments 23 that are sequentially hinged along the length direction of the rail 10, and in the longitudinal direction of the rail 10, the body 22 is The surface of the compartment 23 at least one end remote from the adjacent compartment 23 is provided with an escape door 24 that can be opened and closed, and the inner floor of the compartment 23 of the at least one end of the vehicle body 22 is provided with an escape opening 25 and an escape cover 26 That is, the inner floor of the compartment 23 provided with the escape door 24 is provided with an escape opening 25 and an escape cover 26 . The escape cover 26 is interlocked with the escape door 24 and is used to open and close the escape opening 25. When the rail vehicle 20 is operating normally, the escape door 24 is closed and the escape cover 26 closes the escape port 25 (shown in Figure 67). When an emergency occurs, the rail vehicle 20 is actively or passively parked, the escape door 24 is opened, and the escape cover 26 opens the escape port 25 (as shown in FIG. 68), and the passengers in the carriage 23 can enter the escape passage 11 through the escape port 25. Further evacuated from the escape route 11. Further, even if the rail vehicle 20 is forced to stop at the turn of the rail 10, the escape door 24 does not need to collide with the rail 10 when it is opened, so that the passenger is not evacuated at the turn of the rail 10.

Preferably, in the longitudinal direction of the rail 10, both end faces of the two compartments 23 located at the two ends of the vehicle body 22 are provided with an escape door 24, which is the surface of the current compartment away from the adjacent compartment, in an emergency situation At the same time, the escape door 24 is simultaneously opened at both ends of the vehicle body 22, and a wide air convection passage can be formed, so that toxic gases such as smoke inside the vehicle body 22 can be quickly dissipated. The escape door 24 adopts a flip structure, and the passengers in the vehicle can be quickly opened by simple operation, thereby effectively improving the efficiency of escape.

Specifically, the escape door 24 has a first end 31 and a second end 32, and the second end 32 of the escape door 24 is pivotally mounted on the corresponding compartment 23, wherein the second end 32 of the escape door 24 is adjacent to the roof It is provided that the first end 31 of the escape door 24 is disposed adjacent to the vehicle floor when the escape door 24 is closed.
