Detailed Description

[0041] 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 drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0042] In combination with Figures 1 to 10 , an escape device 20 according to an embodiment of the present invention includes: an escape ladder 21 and a cover plate assembly 22. The escape ladder 21 can be used to connect to the vehicle body 10, and the escape ladder 21 can be placed inside the vehicle body 10 and used for escape in case of emergency. The cover plate assembly 22 can cover the escape ladder 21, and in case of emergency, the cover plate assembly 22 can be unfolded to be part of a passage.

[0043] Specifically, a first end of the escape ladder 21 is adapted to connect to the vehicle body 10. The cover plate assembly 22 is rotatably connected to a second end of the escape ladder 21. The cover plate assembly 22 has a folded position and an unfolded position, and the cover plate assembly 22 can rotate between the folded position and the unfolded position. Wherein, the cover plate assembly 22 is in contact with the escape ladder 21 in the unfolded position, so that the cover plate assembly 22 and the escape ladder 21 jointly construct a passage through which the personnel in the vehicle can leave to reduce personnel and property losses. The cover plate assembly 22 is folded with the escape ladder 21 in the folded position, and the cover plate assembly 22 covers at least a part of the escape ladder 21. The cover plate assembly 22 can be folded together with the escape ladder 21 in the folded position, thereby reducing the size of the escape device 20. Moreover, the shielding effect of the cover plate assembly 22 on the escape ladder 21 can prevent the escape ladder 21 from being exposed and affecting the appearance, and can prevent the escape ladder 21 from being damaged and unable to be used in case of emergency.

[0044] For the escape device 20 according to an embodiment of the present invention, the escape device 20 has a cover plate assembly 22 to shield the escape ladder 21, and the cover plate assembly 22 can be part of a passage after being unfolded. When the escape ladder 21 is not needed, the escape ladder 21 can be stored inside the vehicle body 10 and shielded by the cover plate assembly 22. In this way, the possibility of dust and the like entering the escape ladder 21 is reduced, damage to the escape ladder 21 is avoided, and the escape device 20 cannot be used. Moreover, due to the shielding of the cover plate assembly 22, the exposed structure of the escape device 20 is relatively simple, which is convenient for cleaning the vehicle having the escape device 20. In addition, when the escape ladder 21 is used, the cover plate assembly 22 can be part of a passage. In this way, each part of the escape device 20 is fully utilized, the structure is simplified and the space utilization rate is improved. In addition, the cover plate assembly 22 can be used to extend the passage to more conveniently allow personnel to leave the vehicle (reach the ground, safety net, etc.).

[0045] Among them, the channel in the present invention can be a pedal structure, a slide structure, etc. For example, when the cover assembly 22 is in the deployed position, the cover and at least one of the escape ladder 21 form a ladder structure to facilitate the evacuation of personnel; for another example, when the cover assembly 22 is in the deployed position, the cover assembly 22 and at least one of the escape ladder 21 form a slide structure, and personnel can slide down the channel. Of course, the channel in the present invention can also be set in other forms, which should all be within the scope of protection of the present invention. The present invention is mainly described using the channel of the pedal structure as an example, but this is not a limitation of the scope of protection of the present invention.

[0046] like Figure 7 In some embodiments of the present invention, the escape ladder 21 includes a fixed rod 211 and a first pedal 212, and the fixed rod 211 is hinged to the cover assembly 22. The first pedal 212 is arranged on the fixed rod 211. The fixed rod 211 can provide support for the first pedal 212, and when the escape device 20 is used, the vehicle can be left through the first pedal 212. The escape ladder 21 may include a plurality of first pedals 212, and when the escape device 20 is used, the plurality of first pedals 212 are arranged at intervals inclined from top to bottom. The fixed rod 211 may include one, two or more than three fixed rods 211. When there are two fixed rods 211, the two fixed rods 211 may be arranged in parallel and at intervals, and the first pedal 212 may be connected between the two fixed rods 211, and the two ends of the first pedal 212 may be connected to the two fixed rods 211 respectively, so that the stability and connection strength of the first pedal 212 may be improved; of course, one fixed rod 211 may also be provided, and the fixed rod 211 may be connected to the middle of the first pedal 212.

[0047] like Figure 7 In some examples of the present invention, the cover plate assembly 22 includes: a first cover plate 221 and a second pedal 222. The first cover plate 221 can shield the escape ladder 21 and can also be used as a supporting structure for the second pedal 222. The first cover plate 221 is rotatably connected to the escape ladder 21, and the second pedal 222 is relatively fixedly connected to the first cover plate 221.

[0048] Specifically, when the cover assembly 22 is in the folded position, the second pedal 222 is located on the side of the first cover 221 facing the escape ladder 21, the first pedal 212 and the second pedal 222 are arranged alternately, and the first cover 221 covers at least a portion of the escape ladder 21, so the first cover 221 can be used to shield the escape ladder 21, and since the first pedal 212 and the second pedal 222 are arranged alternately, the occupied space of the escape device 20 can be reduced. When the cover assembly 22 is in the unfolded position, the first pedal 212 and the second pedal 222 are arranged in sequence to construct a passage, and at this time, the first cover 221 can provide support for the second pedal 222, so that the first pedal 212 and the second pedal 222 are configured into a ladder structure.

[0049] In the present invention, the second pedal 222 can be directly disposed on the first cover plate 221, or other supporting structures can be provided to support the second pedal 222, so as to avoid insufficient strength of the first cover plate 221 or damage to the first cover plate 221 when the second pedal 222 is stressed. For example Figure 7 , the cover plate assembly 22 may further include a folding rod 223. The folding rod 223 is stacked and fixedly connected with the first cover plate 221, and the folding rod 223 is rotatably connected to the fixed rod 211. The second pedal 222 is connected to the folding rod 223. Wherein, when the cover plate assembly 22 is in the folded position, the fixed rod 211 and the folding rod 223 are folded on the same side of the first cover plate 221. Thus, the second pedal 222 can be supported by the folding rod 223 to construct a passage.

[0050] In addition, a predetermined distance can be provided between the second pedal 222 and the first cover plate 221. During the use of the escape device 20, there is more space for the feet to step on, facilitating passage.

[0051] For example Figure 7 , in some embodiments of the present invention, the cover plate assembly 22 further includes a hinge seat 224. The hinge seat 224 is vertically connected to the folding rod 223, and the hinge seat 224 is hinged to the fixed rod 211. Stable connection between the cover plate assembly 22 and the fixed rod 211 can be achieved, improving the stability of the escape device 20.

[0052] In addition, the hinge seat 224 can be configured to be lockable to lock the folding rod 223 and the fixed rod 211 after deployment.

[0053] For example Figures 7 to 11 , the escape ladder 21 further includes a connecting curved rod 23. The first end of the connecting curved rod 23 is fixedly connected to the fixed rod 211, and the second end of the connecting curved rod 23 is used to connect to the vehicle body 10. The fixed rod 211 is disposed on the rail vehicle 100 through the connecting curved rod 23, with a simple structure and facilitating the switching of 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 stands upright on the vehicle body 10. At this time, the connecting curved rod 23 can be set in a U shape with the opening facing upward and facing away from the cover plate assembly 22 of the escape ladder 21. When the escape device 20 is in use, the connecting curved rod 23 is set in a U shape with the opening facing downward, and the connecting curved rod 23 is configured to be similar to the form of hooking the bottom of the escape exit, thereby facilitating the improvement of the structural strength and stability of the escape device 20.

[0054] In some embodiments, a limiting member (not shown in the figure) is provided at the second end of the connecting curved rod 23 and is adapted to cooperate with the limiting portion of the rail vehicle 100. By the cooperation of the limiting member of the connecting curved rod 23 and the limiting portion 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.

[0055] 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 provided on the floor plane of the rail vehicle 100. The cooperation structure of the limiting pin and the limiting groove or the limiting hole is simple and reliable.

[0056] Combined with Figure 3 and Figures 7 to 11 , in some embodiments, the connecting curved rod 23 is configured in a U shape. One branch of the connecting curved rod 23 is connected to the fixed rod 211, and the other branch of the connecting curved rod 23 is connected to the vehicle body 10. When the escape ladder 21 needs to be used, the other branch of the connecting curved rod 23 is cooperated with the floor plane of the rail vehicle 100 for people to transfer from the rail vehicle 100 to the rail beam.

[0057] Optionally, the fixed rod 211 is in a hollow tubular shape, and the first end of the connecting curved rod 23 is inserted into the fixed rod 211 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 211 is realized through the bolt, effectively improving the connection strength between the connecting curved rod 23 and the fixed rod 211. Of course, the connecting curved rod 23 and the fixed rod 211 can also be connected together by means of pin connection, rivet connection, etc. In addition, welding and other methods can also be used for connection. Of course, the connecting curved rod 23 can also be connected to the fixed rod 211 in a laminated connection manner. The fixed rod 211 in the present invention is provided in a hollow tubular shape, which can effectively improve the structural strength of the fixed rod 211, reduce the weight of the fixed rod 211, save materials, and reduce the adverse effects caused by stress concentration, rod body defects, etc. Of course, the fixed rod 211 in the present invention can also be set as a solid rod.

[0058] In addition, when the vehicle body 10 is at 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 realize the adjustment of the direction of the passage.

[0059] Optionally, as Figure 10, 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 about a 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 escape ladder 21 is connected to the Y-axis rotating shaft 262.

[0060] In addition, the Y-axis rotating shaft 262 can also be fixedly connected to the Z-axis rotating shaft 261, and the escape device 20 is rotatably connected to the Y-axis rotating shaft 262; of course, the Y-axis rotating shaft 262 can also be rotatably connected to the Z-axis rotating shaft 261, 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.

[0061] As Figure 10 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, and 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 provided separately, 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 be swung in the left and right directions, so that the angle adjustment of the escape ladder 21 in the left and right directions can be realized to facilitate passing through the escape passage.

[0062] In addition, in combination with Figures 1 to 17 , the present invention further provides a rail vehicle 100, and the foregoing escape device 20 can be provided on the rail vehicle 100. Specifically, the rail vehicle 100 according to an embodiment of the present invention 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 closes the escape opening 101 in an openable manner; the escape device 20 is the escape device 20 described above, the escape device 20 is provided at the escape opening 101, and the escape ladder 21 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 cover plate assembly 22.

[0063] The rail vehicle 100 according to an embodiment of the present invention is provided with the aforementioned escape device 20. The cover plate assembly 22 of the escape device 20 is used to cover the escape ladder 21. The escape device 20 has a cover plate assembly 22 to block the escape ladder 21, and after the cover plate assembly 22 is unfolded, it can be used as a part of the passage. When the escape ladder 21 is not needed, the escape ladder 21 can be stored in the vehicle body 10 and covered by the cover plate assembly 22. In this way, the possibility of dust and the like entering the escape ladder 21 is reduced, damage to the escape ladder 21 is avoided, and the inability to use the escape device 20 is avoided. Moreover, due to the shielding of the cover plate assembly 22, the exposed structure of the escape device 20 is relatively simple, which is convenient for cleaning the vehicle with the escape device 20. In addition, when the escape ladder 21 is used, the cover plate assembly 22 can be used as a part of the passage. In this way, each part of the escape device 20 is fully utilized, the structure is simplified, and the space utilization rate is improved. In addition, the cover plate assembly 22 can be used to extend the passage to make it more convenient for people to leave the vehicle (reach the ground, safety net, etc.).

[0064] Optionally, the upper end of the escape door 11 is hinged to the vehicle body 10, and 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 cover plate assembly 22 and the second cover plate 27, it can effectively prevent the first cover plate 221 and the second cover plate 27 from being integrated together and affecting the unfolding of the escape device 20.

[0065] Combined with Figure 3 and Figure 5 , 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 unfolded position, thereby realizing the automatic unfolding of the escape device 20.

[0066] Optionally, the surface of the second cover plate 27 is smoothly connected to the surface of the cover plate assembly 22.

[0067] Optionally, as Figure 7 and Figure 8As 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 escape ladder 21; the second support rod 242 is rotatably connected to the vehicle body 10; the positioning mechanism is sequentially connected to the escape ladder 21, the first support rod 241, the second support rod 242, and the vehicle body 10. When the escape ladder 21 is stored, the first support rod 241 is folded on the escape ladder 21, and the second support rod 242 is folded on the vehicle body 10; when the escape ladder 21 is deployed, the first support rod 241 stands upright on the escape ladder 21, and the second support rod 242 stands upright on the vehicle body 10. That is to say, when the escape ladder 21 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 escape ladder 21 be conveniently achieved to prevent the escape ladder 21 from deviating from the predetermined position, but also the positioning mechanism can be used to construct the form of a handrail to facilitate the passage of personnel.

[0068] Combined with Figures 7 to 10 , 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 escape ladder 21 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, and the third connecting rope 253 is respectively connected to the second support rod 242 and the vehicle body 10. When folding, since the escape ladder 21 is stored in the vehicle body 10, the third connecting rope is in a slack 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 slack state. Similarly, when there is no acting force from the second connecting rope and the third connecting rope, the first connecting rope is also in a slack state. At this time, without the pulling force of the positioning mechanism, the first support rod 241 will fold onto the escape ladder 21, and the second support rod 242 will fold onto the vehicle body 10, thereby realizing the folding of the escape ladder 21, the first support rod 241, and the second support rod 242 to reduce the space occupation; when deploying, the escape ladder 21 extends out of the vehicle body 10, the third connecting rope is tightened, and the distance between the first support rod 241 and the second support rod 242 is relatively far, the second connecting rope 252 is tightened. Similarly, the first connecting rope is also in a tightened state under the acting force of the second connecting rope and the third connecting rope. 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 stand upright, thereby realizing the deployment 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.

[0069] In addition, one end of the first support rod 241 can be hinged to the fixed rod 211, and the other end of the first support rod 241 is provided with a first connection ring and a second connection ring. The first connection ring and the second connection ring are used to connect the positioning mechanism. Specifically, the first connection rope 251 can connect the first connection ring and the fixed rod 211, and the second connection rope 252 can connect the first support rod 241 and the second support rod 242. Similarly, one end of the second support rod 242 can be hinged to the vehicle body 10, and the other end of the second support rod 242 is provided with a third connection ring and a fourth connection ring. The third connection ring and the fourth connection ring are used to connect the positioning mechanism. Specifically, the third connection rope 253 can connect the third connection ring and the vehicle body 10, and the second connection rope 252 can connect the first support rod 241 and the second support rod 242.

[0070] When the escape device 20 is not needed, the escape door 11 is closed, and the escape device 20 is placed inside the rail vehicle 100. In some embodiments, the lower end of the escape ladder 21 is fixed to the rail vehicle 100 through a lower seat body, and the middle or upper end of the escape ladder 21 is fixed to the rail vehicle 100 through an upper seat body. When the escape device 20 is needed, the escape door 11 is opened, the fixing of the escape device 20 by the upper seat body and the lower seat body is released, the escape device 20 is taken out, and the escape ladder 21 is lapped between the rail vehicle 100 and the track beam, so that personnel can be transferred from the rail vehicle 100 to the track beam through the escape device 20, and then leave the track beam to complete the escape.

[0071] Optionally, the escape ladder 21 further includes a positioning seat 243. The positioning seat 243 is arranged on the escape ladder 21. When the cover plate assembly 22 is in the folded position, the positioning seat 243 is limited to the side of the first support rod 241 away from the cover plate assembly 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.

[0072] Specifically, the positioning seat 243 can be arranged on the side surface of the fixed rod 211. The positioning seat 243 can be arranged in an L shape. The combination of the positioning seat 243 and the fixed rod can be configured into a positioning groove structure. When the cover plate assembly 22 is in the folded position, the opening of the positioning groove faces the cover plate assembly 22, so as to realize the positioning of the first support rod 241. In addition, one end of the first support rod is hinged to the fixed rod 211, 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.

[0073] In some embodiments, there is one emergency exit door 11 and one emergency escape ladder 21. The emergency exit door 11 is provided at one of the two ends of the rail vehicle 100, that is, the emergency exit door 11 is provided at the head or the tail of the rail vehicle 100, and the emergency exit door 11 is correspondingly provided. By providing the emergency exit door 11 and the emergency 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 the need to additionally build an emergency escape passage beside the track beam, making the track beam smaller in size and ensuring good landscape of the urban environment.

[0074] In other embodiments, there are two emergency exit doors 11 and two emergency escape ladders 21. One emergency exit door 11 is provided at one of the two ends of the rail vehicle 100, and one emergency escape ladder 21 is correspondingly provided; the other emergency exit door 11 is provided at the other of the two ends of the rail vehicle 100, and the other emergency escape ladder 21 is correspondingly provided; that is, the emergency exit doors 11 and the corresponding emergency escape ladders 21 are provided at both the head and the tail of the rail vehicle 100, enabling people to escape from both ends of the rail vehicle 100.

[0075] In some embodiments, the emergency escape ladder 21 of the rail vehicle 100 is adapted to be provided between the emergency escape passage of the track beam and the emergency exit 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 recess is provided in the middle of the track beam to form an emergency escape passage, enabling people to directly transfer from the rail vehicle 100 to the emergency escape passage on the track beam to complete the escape, without the need to additionally build an emergency escape passage beside the track beam, making the track beam smaller in size and ensuring good landscape of the urban environment.

[0076] The other components and operations of the emergency 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.

[0077] The emergency escape ladder 21 in the present invention is connected to the vehicle body 10 through a hinge, and a cover plate is provided to shield the emergency escape ladder 21, making the interior of the vehicle overall beautiful and coordinated. The cover plate can be automatically opened, without increasing the operation steps and operation difficulty, and the opening time is short.

[0078] The cover plate is divided into two parts, namely the second cover plate 27 and the first cover plate 221. The second cover plate 27 is fixed on the emergency exit door 11 and turns up with the emergency exit door 11 when opened. The first cover plate 221 is connected to the emergency escape ladder 21 through a hinge, and the cover plate can be automatically opened during the downward turning of the emergency escape ladder 21.

[0079] Such as Figure 7As shown in the figure, the escape ladder 21 is provided with three sections of first pedals 212, and the first cover plate 221 is provided with two sections of second pedals 222. When being recycled, fixing the first pedals 212 and the second pedals 222 does not affect each other. After the escape ladder 21 is fully deployed, the two sections of second pedals 222 in the cover plate and the three sections of first pedals 212 in the escape ladder 21 can all be used for passengers to evacuate.

[0080] As Figure 6 shown in the figure, a mechanism 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 smaller turning radius. The escape ladder 21 can rotate around the Y axis and can also rotate around the Z axis.

[0081] In addition, the escape ladder 21 of the present invention can be set to be linked with the escape door 11.

[0082] For example, as Figure 17 shown in the figure, the upper end of the escape door 11 is hinged to the upper side of the escape opening 101 and is adapted to be turned upwards to open the escape opening 101. A first magnetic member 293 is provided on the escape door 11, a pulling 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 pulling rope 291. When the escape door 11 is opened, it is adapted to drive the escape ladder 21 to turn outwards through the pulling rope 291.

[0083] 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 pulling rope 291 will drive the escape ladder 21 to turn and open. When the escape ladder 21 is deployed to a certain angle, at this time, the escape ladder 21 can continue to deploy under the action of gravity and inertia. Under the action of gravity, the momentum of the escape ladder 21 is sufficient to separate the first magnetic member 293 and the second magnetic member 292, and the pulling rope 291 can also be separated from the escape door 11, thus avoiding the escape door 11 from affecting the continuous deployment of the escape ladder 21 and realizing the linkage between the escape door 11 and the escape ladder 21. Among them, the first magnetic member 293 and the second magnetic member 292 can both be permanent magnets; or one of the first magnetic member 293 and the second magnetic member 292 is a permanent magnet and the other is a magnetic conductor (such as an iron block, etc.); in addition, at least one of the first magnetic member 293 and the second magnetic member 292 can also be set as an electromagnet, etc.

[0084] Another example, as Figures 12 to 16, 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 downwards. Thus, the 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 meshing. 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 mesh (the teeth are corresponding 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 are meshed, 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.
