Specifically, the escape ladder 21 includes a fixing portion 211 and a telescopic portion 212, a first end of the fixing portion 211 is adapted to be connected to the vehicle body 10, the telescopic portion 212 is telescopically connected to the fixing portion 211 between a retracted position and an extended position, and the telescopic portion 212 is extended from a second end of the fixing portion 211 in the extended position so that the fixing portion 211 and the telescopic portion 212 together construct a passage. The first cover plate 22 is rotatably connected to the second end of the fixing portion 211 between a folded position and an unfolded position, wherein the first cover plate 22 is folded to one side with the escape ladder 21 in the folded position and covers at least a portion of the escape ladder 21; the first cover plate 22 is turned over to the other side of the escape ladder 21 in the deployed position.

According to the escape device 20 for the vehicle of the embodiment of the invention, the telescopic part 212 can be retracted to reduce the length of the escape ladder 21, and the telescopic part 212 can be extended to extend the escape ladder 21 so as to facilitate passage, the length of the escape ladder 21 is smaller when the telescopic part 212 is retracted, the storage of the escape ladder 21 can be facilitated, and the effective shielding of the escape ladder 21 can be realized through the first cover plate 22. When the telescopic portion 212 is extended to construct a passageway, the first cover plate 22 may be turned over to the other side of the escape ladder 21 to avoid affecting a person passing through the escape ladder 21, and the first cover plate 22 may also function as a buffer so that the escape apparatus 20 can be stably supported to the escape passageway on the track.

Wherein, the passageway in the invention can be a pedal structure, a slide structure, etc., for example, when the first cover plate is in the first unfolding position, at least one of the first cover plate and the escape ladder 21 is formed into a ladder structure so as to facilitate personnel evacuation; for another example, at least one of the first cover panel and the escape ladder 21 may be formed in a slide configuration with the first cover panel in the deployed position, and personnel may slide down the passageway.
