The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
Referring to fig. 1 to 9, an escape apparatus 20 for a vehicle according to an embodiment of the present invention includes an escape ladder 21 and a first cover plate 22, the escape ladder 21 may be used to connect a vehicle body 10, and the escape ladder 21 may be placed in the vehicle body 10, and the first cover plate 22 may cover the escape ladder 21.
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 in which the first cover plate 22 is folded on one side of the escape ladder 21 and covers at least a portion of the escape ladder 21 and an unfolded position in which the first cover plate 22 is flipped over to the other side of the escape ladder 21.
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.
The passageway in the present invention may be a pedal structure, a slide structure, or the like, for example, when the first cover plate is in the first extended position, at least one of the first cover plate and the escape ladder 21 is formed as a ladder structure to facilitate evacuation of a person, and for example, when the first cover plate is in the extended position, at least one of the first cover plate and the escape ladder 21 is formed as a slide structure from which a person can slide down. Of course, the channels of the present invention may be provided in other forms, which are within the scope of the present invention.

By the locking of the locking mechanism 213, the escape ladder 21 can be stably maintained at the retracted position, so that the escape ladder 21 can be stably stored in the vehicle body 10, the space utilization rate is improved, and in addition, the first cover plate 22 can be conveniently and stably turned between the folded position and the unfolded position, and the first cover plate 22 is prevented from being influenced after the extension part 212 extends.
The locking mechanism 213 may also be arranged to release the locking of the escape ladder 21, for example by controlling the locking mechanism 213 by other control arrangements. In addition, to facilitate use of escape apparatus 20, escape apparatus 20 may further include an unlocking mechanism 221, wherein unlocking mechanism 221 is mounted on first cover 22, and when first cover 22 is in the extended position, unlocking mechanism 221 triggers locking mechanism 213 to unlock telescoping portion 212. Thus, when the first cover 22 is in the folded position, since the unlocking mechanism 221 is not moved in place, the locking mechanism 213 is in the position of locking the telescopic part 212, and the telescopic part 212 is in the retracted position, so that the influence on the overturning of the first cover 22 is effectively avoided, when the first cover 22 is overturned to the unfolded position, the first cover 22 is overturned in place, and at this time, the unlocking mechanism 221 on the first cover 22 unlocks the locking mechanism 213, so that the telescopic part 212 extends out to construct a passage for passing. The problem that the first turning plate cannot be turned to the unfolding position due to the fact that the telescopic part 212 moves before the first cover plate 22 is effectively avoided.

In addition, the locking mechanism 213 may further include an elastic structure by which a force toward the locking expansion and contraction portion 212 is applied to the locking piece 2132.
Alternatively, the first end of the first cover plate 22 is rotatably connected with the second end of the fixing portion 211, and the second end of the first cover plate 22 is connected with a flexible structure.
