Detailed implementation manners

[0043] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0044] Combined with Figures 1 to 9 , the emergency escape device 20 for a vehicle according to an embodiment of the present invention, the emergency escape device 20 includes: an emergency escape ladder 21 and a first cover plate 22. The emergency escape ladder 21 can be used to connect to the vehicle body 10, and the emergency escape ladder 21 can be placed inside the vehicle body 10. The first cover plate 22 can cover the emergency escape ladder 21.

[0045] Specifically, the emergency escape ladder 21 includes a fixing part 211 and a telescopic part 212. The first end of the fixing part 211 is adapted to connect to the vehicle body 10. The telescopic part 212 is telescopically connected to the fixing part 211 between a retracted position and an extended position. The telescopic part 212 extends from the second end of the fixing part 211 in the extended position, so that the fixing part 211 and the telescopic part 212 jointly construct a passage. The first cover plate 22 is rotatably connected to the second end of the fixing part 211 between a folded position and an unfolded position. Wherein, the first cover plate 22 is folded on one side of the emergency escape ladder 21 in the folded position and covers at least a part of the emergency escape ladder 21; the first cover plate 22 is flipped to the other side of the emergency escape ladder 21 in the unfolded position.

[0046] According to the escape device 20 for a vehicle according to an embodiment of the present invention, the telescopic portion 212 can be retracted to reduce the length of the escape ladder 21, and the telescopic portion 212 can be extended to extend the escape ladder 21 for easy passage. When the telescopic portion 212 is retracted, the length of the escape ladder 21 is smaller, which facilitates the storage of the escape ladder 21, and the first cover plate 22 can effectively shield the escape ladder 21. When the telescopic portion 212 is extended to form a passage, the first cover plate 22 can be flipped to the other side of the escape ladder 21 to avoid affecting the passage of personnel through the escape ladder 21, and the first cover plate 22 can also play a buffering role so that the escape device 20 can be stably supported on the escape passage on the track.

[0047] Among them, the passage in the present invention can be a pedal structure, a slide structure, etc. For example, when the first cover plate is in the first unfolded position, the first cover plate and at least one of the escape ladders 21 form a ladder structure to facilitate the evacuation of personnel; for another example, when the first cover plate is in the unfolded position, the first cover plate and at least one of the escape ladders 21 form a slide structure, and personnel can slide down through the passage. Of course, the passage in the present invention can also be set in other forms, which should all be within the protection scope of the present invention. The present invention mainly takes the passage of the pedal structure as an example for illustration, but this is not a limitation on the protection scope of the present invention.

[0048] As Figure 6 , in some embodiments of the present invention, the escape ladder 21 further includes a locking mechanism 213. The locking mechanism 213 is installed on the fixed portion 211, and the locking mechanism 213 is configured to lock the telescopic portion 212 in the retracted position. Through the locking of the locking mechanism 213, the escape ladder 21 can be stably maintained in the retracted position, enabling the escape ladder 21 to be stably stored in the vehicle body 10, improving the space utilization rate. In addition, it can also facilitate the first cover plate 22 to stably flip between the folded position and the unfolded position, avoiding the telescopic portion 212 from affecting the flipping of the first cover plate 22 after extension.

[0049] The locking mechanism 213 can also be configured to release the locking of the escape ladder 21. For example, the locking mechanism 213 can be controlled by other control structures. In addition, for the convenience of using the escape device 20, the escape device 20 can further include an unlocking mechanism 221. The unlocking mechanism 221 is installed on the first cover plate 22. When the first cover plate 22 is in the deployed position, the unlocking mechanism 221 touches the locking mechanism 213 to unlock the telescopic part 212. In this way, when the first cover plate 22 is in the folded position, since the unlocking mechanism 221 does not move into 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, effectively avoiding affecting the flipping of the first cover plate 22. When the first cover plate 22 is flipped to the deployed position, the first cover plate 22 is flipped in place. At this time, the unlocking mechanism 221 located on the first cover plate 22 unlocks the locking mechanism 213, enabling the telescopic part 212 to extend, so as to construct a passage for passage. This effectively avoids the problem that the telescopic part 212 moves before the first cover plate 22, resulting in the first flap being unable to be flipped to the deployed position.

[0050] Optionally, as Figure 6 shown, the locking mechanism 213 includes a mounting base 2131 and a locking member 2132. The mounting base 2131 is fixedly installed on the fixed part 211. The locking member 2132 is rotatably connected to the mounting base 2131 to form a lever mechanism. The locking member 2132 has a fulcrum, a power end and a resistance end located on both sides of the fulcrum. The resistance end is adapted to lock the telescopic part 212. When the first cover plate 22 is in the deployed position, the unlocking mechanism 221 is adapted to touch the power end to unlock the telescopic part 212. The stable locking of the telescopic part 212 by the locking mechanism 213 can be achieved, and the unlocking of the locking mechanism 213 by the unlocking mechanism 221 can be facilitated.

[0051] Specifically, in the present invention, when the telescopic part 212 retracts, one end of the locking member 2132 can pass through the fixed part 211 and be inserted into the telescopic part 212, thereby achieving the locking of the telescopic part 212. The locking member 2132 is configured in a lever structure. When the first flap is flipped to the deployed position, the unlocking mechanism 221 will touch the power end of the locking member 2132, thereby pulling out the resistance end of the locking member 2132 from the position of locking the telescopic part 212, realizing the unlocking of the telescopic part 212, so that the telescopic part 212 can extend and facilitate passage.

[0052] Specifically, a positioning post 2133 is provided at the resistance end of the locking member 2132, and a positioning hole (not shown in the figure) is provided on the side surface of the telescopic portion 212. The positioning post 2133 is adapted to be inserted into the positioning hole to lock the telescopic portion 212, and the positioning post 2133 is adapted to be disengaged from the positioning hole to release the telescopic portion 212. Among them, when the locking member 2132 is in the position of locking the telescopic portion 212, the locking member 2132 can be configured in a hook shape, so as to realize the locking of the telescopic portion 212, and the locking effect on the telescopic portion can be improved. Among them, a mating hole opposite to the positioning hole can be provided on the fixing portion. During the process of the locking member 2132 locking the telescopic portion, the positioning post 2133 passes through the mating hole and is inserted into the positioning hole.

[0053] In addition, the locking member 2132 of the present invention can be configured in a rod shape. Among them, the locking member 2132 includes a first rod portion, a second rod portion and a positioning post. The first rod portion and the second rod portion are connected at the fulcrum of the locking member 2132 and are connected to the mounting seat 2131. The positioning post is connected to the second rod portion and is perpendicular to the second rod portion. The first rod portion and the second rod portion can be configured to extend obliquely relative to each other, so that when the positioning post locks the telescopic portion 212, the first rod portion can tilt away from the fixing portion. In addition, the locking mechanism 213 can further include an elastic structure, and the elastic structure applies a force to the locking member 2132 toward the telescopic portion 212 to be locked.

[0054] Optionally, the first end of the first cover plate 22 is rotatably connected to the second end of the fixing portion 211, and a flexible structure is connected to the second end of the first cover plate 22. The second end of the first cover plate 22 can be supported on the track or the escape passage on the track, avoiding the violent collision of the escape device 20 against the track or the escape passage on the track when the escape device 20 flips to the escape position, effectively improving the stability of the escape device 20, and the position of the first cover plate 22 can be stabilized.

[0055] Optionally, as Figure 6 shown, the escape device 20 further includes a hinge seat 222. The hinge seat 222 is vertically connected to the first cover plate 22 and is hinged to the fixing portion 211. Among them, when the telescopic portion 212 is in the retracted position, the first cover plate 22 is adapted to flip on the opposite sides of the escape ladder 21. That is to say, the distance between the two hinge points of the hinge seat 222 is not less than the distance from the hinge point of the hinge seat 222 and the fixing portion 211 to the free end of the telescopic portion 212. In this way, when the first flap flips from the folded position to the unfolded position, or from the first folded unfolded position to the unfolded position, it can flip stably, avoiding the escape ladder 21 from affecting the flipping of the first flap.

[0056] Optionally, as Figure 5As shown, the fixing part 211 includes a fixing rod 2111 and a first pedal 2112. The first end of the fixing rod 2111 is adapted to be connected to the vehicle body 10, and the second end is hinged to the first cover plate 22. The first pedal 2112 is arranged on the fixing rod 2111. The first pedal 2112 is arranged on the fixing rod 2111. The fixing rod 2111 can provide support for the first pedal 2112. When using the escape device 20, one can leave the vehicle through the first pedal 2112. Among them, the escape ladder 21 can include a plurality of first pedals 2112. When the escape device 20 is in use, the plurality of first pedals 2112 are arranged at intervals and inclined from top to bottom. The fixing rod 2111 can include one, two or more than three. When there are two fixing rods 2111, the two fixing rods 2111 can be arranged in parallel at intervals, and the first pedal 2112 is connected between the two fixing rods 2111, and both ends of the first pedal 2112 are respectively connected to the two fixing rods 2111, so as to improve the stability and connection strength of the first pedal 2112; of course, one fixing rod 2111 can also be provided, and the fixing rod 2111 can be connected to the middle of the first pedal 2112.

[0057] Optionally, as Figure 5 shown, the telescopic part 212 includes a telescopic rod 2121 and a second pedal 2122. The telescopic rod 2121 is telescopically inserted into the fixing rod 2111, and the second pedal 2122 is arranged on the telescopic rod 2121. The telescopic rod 2121 can be used as a support structure for the second pedal 2122.

[0058] Specifically, when the telescopic rod 2121 is in the retracted position, the distance between the second pedal 2122 and the fixing part 211 is smaller, which can reduce the occupied space of the escape device 20; when the telescopic rod 2121 extends, the distance between the second pedal 2122 and the fixing part 211 is larger, and the telescopic rod 2121 can provide support for the second pedal 2122, so as to facilitate the first pedal 2112 and the second pedal 2122 to be configured into a ladder structure.

[0059] In addition, when the first cover plate 22 is flipped to the unfolded position, the first cover plate 22 is located below the telescopic part 212. At this time, a predetermined distance can be spaced between the second pedal 2122 and the first cover plate 22. During the use of the escape device 20, there is a larger space for stepping on, which is convenient for passing.

[0060] Optionally, the escape ladder 21 further includes a connecting curved rod 23, the first end of which is fixedly connected to the first end of the fixed rod 2111, and the second end of the connecting curved rod 23 is used to connect to the vehicle body 10. The fixed rod 2111 is arranged on the rail vehicle 100 through the connecting curved rod 23, which has a simple structure and is convenient for switching the escape ladder 21 between the use state and the non-use state. When the escape device 20 is not needed, the escape device 20 is erected on the vehicle body 10, and the connecting curved rod 23 can be set to a U-shape with an upward opening and facing the side of the escape ladder 21 away from the first cover plate 22. When the escape device 20 is used, the connecting curved rod 23 is set to a U-shape with an downward opening, and the connecting curved rod 23 is constructed in a form similar to hooking the bottom of the take-out outlet, so as to facilitate improving the structural strength and stability of the escape device 20.

[0061] In some embodiments, a second end of the connecting curved rod 23 is provided with a stopper, which is suitable for cooperating with a stopper of the rail vehicle 100. By cooperating with the stopper of the connecting curved rod 23 and the stopper of the rail vehicle 100, when the escape ladder 21 needs to be used, the upper end of the escape ladder 21 can be fixed on the rail vehicle 100, so that the escape ladder 21 can be more stable for people to walk on and avoid shaking.

[0062] In some embodiments, the limiting member is a limiting pin, and the limiting portion is a limiting groove or a limiting hole. In some embodiments, the limiting portion is arranged on the floor plane of the rail vehicle 100. The matching structure of the limiting pin and the limiting groove or the limiting hole is simple and reliable.

[0063] like Figure 5 As shown, in some embodiments, the connecting bent rod 23 is configured in a U-shape. One branch of the connecting bent rod 23 is connected to the fixed rod 2111, and the other branch of the connecting bent rod 23 is connected to the vehicle body 10. When the escape ladder 21 is needed, the other branch of the connecting bent rod 23 is matched with the floor plane of the rail vehicle 100 to allow personnel to transfer from the rail vehicle 100 to the rail beam.

[0064] Optionally, the fixed rod 2111 is in the shape of a hollow tube. The first end of the connecting curved rod 23 is inserted into the first end of the fixed rod 2111 and connected by a fixing member. The fixing member can be a bolt, and the stable connection between the connecting curved rod 23 and the fixed rod 2111 is achieved through the bolt, effectively improving the connection strength between the connecting curved rod 23 and the fixed rod 2111. Of course, the connecting curved rod 23 and the fixed rod 2111 can also be connected together by means of pin connection, rivet connection, etc. In addition, welding or other methods can also be used for connection. Of course, the connecting curved rod 23 can also be connected to the fixed rod 2111 in a laminated manner. The fixed rod 2111 in the present invention is set as a hollow tube, which can effectively improve the structural strength of the fixed rod 2111, reduce the weight of the fixed rod 2111, save materials, and reduce the adverse effects caused by stress concentration, rod body defects, etc. Of course, the fixed rod 2111 in the present invention can also be set as a solid rod.

[0065] In addition, when the vehicle body 10 is in different positions on the track, the position of the escape device 20 needs to be adjusted. Therefore, a steering mechanism can be provided in the present invention to realize the steering of the escape device 20, so as to adjust the direction of the passage.

[0066] Optionally, as Figure 7 shown, the escape device 20 further includes a steering mechanism. The steering mechanism includes a Z-axis rotating shaft 261 and a Y-axis rotating shaft 262. The Z-axis rotating shaft 261 is adapted to be rotatably connected to the vehicle body 10 around the vertical axis; the Y-axis rotating shaft 262 is rotatably connected to the Z-axis rotating shaft 261, and the Y-axis rotating shaft 262 is perpendicular to the vertical axis. Among them, the fixing part 211 is connected to the Y-axis rotating shaft 262.

[0067] In addition, the Y-axis rotating shaft 262 and the Z-axis rotating shaft 261 can also be fixedly connected, and the escape device 20 is rotatably connected to the Y-axis rotating shaft 262; of course, the Y-axis rotating shaft 262 and the Z-axis rotating shaft 261 can also be rotatably connected, and the escape device 20 is rotatably connected to the Y-axis rotating shaft 262. By providing the steering mechanism, the steering of the escape device 20 can be realized to facilitate passage.

[0068] As Figure 7As shown, the Z-axis rotating shaft 261 is rotatably connected to the vehicle body 10, and the rotation center axis of the Z-axis rotating shaft 261 relative to the vehicle body 10 extends in the up and down direction; the Y-axis rotating shaft 262 is rotatably connected to the Z-axis rotating shaft 261, the rotation center axis of the Y-axis rotating shaft 262 relative to the Z-axis rotating shaft 261 extends in the horizontal direction, and the rotation center axis of the Y-axis rotating shaft 262 relative to the Z-axis rotating shaft 261 is perpendicular to the rotation center axis of the Z-axis rotating shaft 261 relative to the vehicle body 10. The Z-axis rotating shaft 261 can be set in a block shape; alternatively, a connecting seat can be additionally provided, the Z-axis rotating shaft 261 is connected to the connecting seat, and the Y-axis rotating shaft 262 is rotatably connected to the connecting seat, so as to realize the rotation of the Y-axis rotating shaft 262 relative to the Z-axis rotating shaft 261. During use, since the escape ladder 21 is connected to the Y-axis rotating shaft 262, the escape ladder 21 can be flipped in the up and down direction; and since the Z-axis rotating shaft 261 is rotatably connected to the vehicle body 10, the escape ladder 21 can swing in the left and right directions, so that the angle of the escape ladder 21 can be adjusted in the left and right directions to facilitate passing through the escape passage.

[0069] Combined with Figures 1 to 14 , according to another embodiment of the present invention, the rail vehicle 100 includes: a vehicle body 10, an escape door 11 and an escape device 20. An escape opening 101 is provided on the vehicle body 10; the escape door 11 closably closes the escape opening 101; the escape device 20 is the escape device 20 for a vehicle according to the foregoing, the escape device 20 is provided at the escape opening 101, and the first end of the fixing part 211 is rotatably connected to the bottom of the escape opening 101. Among them, the escape ladder 21 is adapted to stand upright between the escape door 11 and the first cover plate 22.

[0070] According to the rail vehicle 100 of the embodiment of the present invention, the foregoing escape device 20 is provided. 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 for easy passage. When the telescopic part 212 is retracted, the length of the escape ladder 21 is smaller, which is convenient for the storage of the escape ladder 21, and the first cover plate 22 can effectively block the escape ladder 21. When the telescopic part 212 is extended to construct a passage, the first cover plate 22 can be flipped to the other side of the escape ladder 21 to avoid affecting the passage of people through the escape ladder 21, and the first cover plate 22 can also play a buffering role so that the escape device 20 can stably support the escape passage on the track.

[0071] Optionally, combined with Figure 2 and Figure 4, the upper end of the escape door 11 is hinged to the vehicle body 10. A second cover plate 27 is provided on the escape door 11, and the second cover plate 27 covers the upper part of the escape device 20. By splitting the structure for covering the escape ladder 21 into the first cover plate 22 and the second cover plate 27, it can effectively prevent the integration of the first cover plate 22 and the second cover plate 27 from affecting the deployment of the escape device 20.

[0072] Optionally, the end of the second cover plate 27 extends downward and hooks the upper end of the escape device 20. In this way, when the escape door 11 is opened, the second cover plate 27 can hook the escape device 20, so that the escape ladder 21 rotates to the deployed position, thus realizing the automatic deployment of the escape device 20.

[0073] Optionally, the surface of the second cover plate 27 is smoothly connected to the surface of the first cover plate 22.

[0074] Optionally, as Figure 5 , Figure 8 and Figure 9 shown, in some embodiments of the present invention, the rail vehicle 100 further includes a first support rod 241, a second support rod 242 and a positioning mechanism. The first support rod 241 is rotatably connected to the fixing part 211; the second support rod 242 is rotatably connected to the vehicle body 10; the positioning mechanism is sequentially connected to the fixing part 211, the first support rod 241, the second support rod 242 and the vehicle body 10. When the fixing part 211 is stored, the first support rod 241 is folded on the fixing part 211, and the second support rod 242 is folded on the vehicle body 10; when the fixing part 211 is deployed, the first support rod 241 stands upright on the fixing part 211, and the second support rod 242 stands upright on the vehicle body 10. That is to say, when the fixing part 211 is stored in the vehicle body 10, due to the storage of the first support rod 241 and the second support rod 242, the occupied space of the escape device 20 can be reduced. When in need of use, the positioning mechanism will be supported by the first support rod 241 and the second support rod 242. In this way, not only can the effective positioning of the fixing part 211 be conveniently realized to prevent the fixing part 211 from deviating from the predetermined position, but also the form of a handrail can be constructed by the positioning mechanism to facilitate the passage of personnel.

[0075] As Figure 5, the positioning mechanism includes a first connecting rope 251, a second connecting rope 252, and a third connecting rope 253. The first connecting rope 251 is respectively connected to the fixing part 211 and the first support rod 241. The second connecting rope 252 is respectively connected to the first support rod 241 and the second support rod 242. The third connecting rope 253 is respectively connected to the second support rod 242 and the vehicle body 10. During folding, since the fixing part 211 is received in the vehicle body 10, the third connecting rope is in a relaxed state. Moreover, the distance between the first support rod 241 and the second support rod 242 is relatively close, and the second connecting rope 252 is also in a relaxed state. Similarly, when there is no acting force from the second connecting rope and the third connecting rope on the first connecting rope, the first connecting rope is also in a relaxed state. At this time, without the pulling force of the positioning mechanism, the first support rod 241 will fold onto the fixing part 211, and the second support rod 242 will fold onto the vehicle body 10, thereby realizing the folding of the fixing part 211, the first support rod 241, and the second support rod 242 to reduce the space occupation. When unfolding, the fixing part 211 extends out of the vehicle body 10, the third connecting rope is tightened. Moreover, the distance between the first support rod 241 and the second support rod 242 is relatively far, and the second connecting rope 252 is tightened. Similarly, under the acting force of the second connecting rope and the third connecting rope, the first connecting rope is also in a tightened state. Moreover, due to the action of the first connecting rope 251, the second connecting rope 252, and the third connecting rope 253, the first support rod 241 and the second support rod 242 are erected, thereby realizing the unfolding of the first connecting rope 251, the second connecting rope 252, the third connecting rope 253, the first support rod 241, and the second support rod 242.

[0076] Optionally, the positioning mechanism can also be manually pulled by a person to adjust the position of the escape ladder 21. In some embodiments, the first connecting rope 251, the second connecting rope 252, and the third connecting rope 253 are all flexible ropes.

[0077] Optionally, as Figure 5 shown, the escape ladder 21 further includes a positioning seat 243. The positioning seat 243 is provided on the fixing part 211. When the first cover plate is in the folding position, the positioning seat 243 is limited to the side of the first support rod 241 away from the first cover plate 22. The positioning of the first support rod 241 can be realized through the positioning seat 243, so that the first support rod 241 can be stably maintained in the folded state and can be conveniently moved towards the unfolded state.

[0078] In addition, the positioning seat 243 can be arranged on the side surface of the fixing part 211. The positioning seat 243 can be arranged in an L shape. The combination of the positioning seat 243 and the fixing part 211 can be configured into a positioning groove structure. When the first cover plate is in the folding position, the opening of the positioning groove faces the first cover plate 22, so as to realize the positioning of the first support rod 241. One end of the first support rod is hinged to the escape ladder 21, and the other end of the first support rod is provided with a first connection ring and a second connection ring. One end of the second support rod is hinged to the vehicle body, and the other end of the second support rod is provided with a third connection ring and a fourth connection ring.

[0079] In some embodiments, both the escape door 11 and the escape ladder 21 are one. The escape door 11 is arranged at one of the two ends of the rail vehicle 100, that is, the escape door 11 is arranged at the head or the tail of the rail vehicle 100, and the escape door 11 is correspondingly arranged. By arranging the escape door 11 and the escape ladder 21 at the head or the tail of the rail vehicle 100, people can directly transfer from the rail vehicle 100 to the track beam to complete the escape, without additionally building an escape passage beside the track beam, making the track beam smaller in size and ensuring good landscape of the urban environment.

[0080] In other embodiments, both the escape door 11 and the escape ladder 21 are two. One escape door 11 is arranged at one of the two ends of the rail vehicle 100, and one escape ladder 21 is correspondingly arranged; the other escape door 11 is arranged at the other end of the two ends of the rail vehicle 100, and the other escape ladder 21 is correspondingly arranged; that is, both the head and the tail of the rail vehicle 100 are provided with the escape door 11 and the corresponding escape ladder 21, so that people can escape from both ends of the rail vehicle 100.

[0081] In some embodiments, the escape ladder 21 of the rail vehicle 100 is adapted to be arranged between the escape passage of the track beam and the escape door 11 of the rail vehicle 100, so that people can transfer from the rail vehicle 100 to the track beam to complete the escape. In some embodiments, a concave part is formed in the middle of the track beam to form an escape passage, so that people can directly transfer from the rail vehicle 100 to the escape passage on the track beam to complete the escape, without additionally building an escape passage beside the track beam, making the track beam smaller in size and ensuring good landscape of the urban environment.

[0082] The other components and operations of the escape ladder 21, the rail vehicle 100 and the rail transit system according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0083] As Figure 4 shown, the escape ladder 21 is hinged to the vehicle body 10, and a cover plate is provided to shield the escape ladder 21, making the interior of the vehicle beautiful and coordinated as a whole. The cover plate can be automatically opened, without increasing the operation steps and operation difficulty, and the opening time is short.

[0084] As Figure 4 shown, the cover plate is divided into two parts. The second cover plate 27 is fixed on the escape door 11 and, when opened, turns up with the escape door 11. The first cover plate 22 is hinged to the escape ladder 21. During the downward turning of the escape ladder 21, the cover plate can be automatically opened. The bottom end of the first cover plate 22 is made of rubber plate to avoid interference between the cover plate and the escape net after the cover plate turns down in place. As Figure 6 shown, to avoid interference between the turning of the cover plate and the extension of the pedal, the escape ladder 21 is provided with a locking mechanism 213. When the trigger block triggers the locking mechanism 213 after the cover plate turns down in place, the pedal can extend.

[0085] An institution is provided to make the escape ladder 21 swing left and right with a relatively large swing angle so that it can adapt to a curve with a relatively small turning radius. The escape ladder 21 can rotate around the Y axis and can also rotate around the Z axis.

[0086] In addition, the escape ladder 21 of the present invention can be set to be linked with the escape door 11.

[0087] For example, as Figure 15 shown, the upper end of the escape door 11 is hinged to the upper side of the escape opening 101 and is adapted to turn up to open the escape opening 101. A first magnetic member 293 is provided on the escape door 11, a pull rope 291 is provided on the escape ladder 21, and a second magnetic member 292 adapted to be attracted to the first magnetic member 293 is provided on the pull rope 291. When the escape door 11 is opened, it is adapted to drive the escape ladder 21 to turn and open through the pull rope 291. When the escape opening 101 needs to be used, only the escape door 11 needs to be opened. During the opening process of the escape door 11, the pull rope 291 will drive the escape ladder 21 to turn and open. When the escape ladder 21 is unfolded to a certain angle, at this time, the escape ladder 21 can continue to unfold under the action of gravity and inertia. At this time, the pull rope 291 can also be separated from the escape door 11, thus avoiding the escape door 11 from affecting the continuous unfolding of the escape ladder 21, and realizing the linkage between the escape door 11 and the escape ladder 21.

[0088] For another example, in combination with Figures 10 to 14, a transmission mechanism can also be set to realize the linkage between the escape door 11 and the escape ladder 21. The transmission mechanism includes a driving wheel 281, a transmission member 282, a driven wheel 285 and a synchronous belt 286. The driving wheel 281 is connected to the escape door 11, the transmission member 282 is connected to the vehicle body 10, the driven wheel 285 is connected to the escape ladder 21 and is in transmission connection with the transmission member 282; the synchronous belt 286 is respectively connected to the driving wheel 281 and the transmission member 282. The driving wheel 281 can rotate following the escape door 11. When the driving wheel 281 rotates, the movement will be transmitted to the transmission member 282 through the synchronous belt 286, and the transmission member 282 will drive the driven wheel 285 to rotate, thereby driving the escape ladder 21 to turn downward. Thus, stable transmission between the escape door 11 and the escape ladder 21 can be realized through the transmission mechanism, which is convenient for realizing the power transmission of the escape door 11 and the escape ladder 21. The transmission mechanism further includes a supporting wheel 287, and the supporting wheel 287 is arranged on the vehicle body 10 and supports the synchronous belt 286. A plurality of supporting wheels 287 are arranged at intervals in the vertical direction at the escape opening 101 of the vehicle body 10, and the plurality of supporting wheels 287 configure the synchronous belt 286 to extend along the escape opening 101 in the vertical direction. The transmission member 282 further includes a transmission wheel 284, and at least one of the transmission wheel 284 and the driven wheel 285 is a gear with missing teeth, so that the transmission wheel 284 meshes with the driven wheel 285 after the escape door 11 is opened by a predetermined angle. By setting one of the transmission wheel 284 and the driven wheel 285 as a gear with missing teeth, intermittent transmission can be realized. The transmission wheel 284 includes a first gear section and a first transition section, and the driven wheel 285 includes a second gear section and a second transition section. Among them, a transition rod 288 is arranged on the transmission wheel 284, the transition rod 288 is arranged on the first transition section, a stop rod 289 is arranged on the driven wheel 285, and the stop rod 289 is arranged on the second transition section. The transition rod 288 cooperates with the stop rod 289 to be suitable for the first gear section and the second gear section to enter into engagement. Specifically, when the escape door 11 is just opened, the first transition section of the transmission wheel 284 cooperates with the second transition section of the driven wheel 285. In this way, the transmission wheel 284 will be separated from the driven wheel 285 and cannot perform transmission; after the escape door 11 is opened by a predetermined angle, the transition rod 288 contacts the stop rod 289, and with the transmission of the transmission wheel 284, the transmission wheel 284 and the driven wheel 285 gradually synchronize, and the first gear section and the second gear section are in a state of being ready to engage (the teeth correspond to each other), and with the further rotation of the transmission wheel 284, the first gear section on the transmission wheel 284 and the second gear section on the driven wheel 285 will engage with each other, so that the driven wheel 285 can be driven to rotate by the transmission wheel 284, and then the escape door 11 drives the escape ladder 21 to unfold. Thus, the stability of power transmission is improved. Transmission mechanisms are arranged on both the left and right sides of the escape opening 101. By arranging the transmission mechanisms on both the left and right sides of the escape opening 101, the space occupied by the transmission mechanisms can be reduced, and the passing efficiency can be improved. Moreover, the stable transmission of power between the escape door 11 and the escape ladder 21 can also be improved, avoiding problems such as insufficient power or power being biased left or right.
