The middle position of the lifting beam is recessed upward to form a lifting section and an installation section connected to both ends of the lifting section. The lifting section is used to connect the evacuation staircase, and the installation section is used to connect the fixed bracket.

[0012] In some embodiments, the lifting beam has a flange on its side, and the flange is located on the side of the lifting beam away from the fixed support.

[0013] In some embodiments, the evacuation staircase includes a rotating component and a staircase body, the rotating component being connected to the fixing component and the staircase body respectively;

[0014] The first driving component is connected to the fixed component and the rotating component respectively, and the second driving component is connected to the rotating component and the stair body respectively.

[0015] In some embodiments, there are two of each of the rotating member, the first driving member, and the second driving member, and the two rotating members, the two first driving members, and the two second driving members are spaced apart, and the stair body is connected to the two rotating members;

[0016] Each of the rotating components includes a first rotating segment and a second rotating segment arranged at an included angle, the first rotating segment being connected to the fixed component and the second rotating segment being connected to the stair body; the first driving component and the second driving component on each side are respectively connected to the intersection of the first rotating segment and the second rotating segment of the rotating component on the corresponding side.

[0017] In some embodiments, the staircase body includes two folding assemblies spaced apart and a plurality of treads disposed between the two folding assemblies. Each folding assembly includes an unfolding rod, at least one tread rod, and at least one support rod. The tread rod and the support rod are arranged in pairs. The middle position of each pair of tread rods is rotatably connected to the middle position of the support rod to form a scissor lift. At least two scissor lifts are connected end to end to form a scissor lift structure. One end of the unfolding rod is connected to the end of the second rotating segment away from the first rotating segment. The other end of the unfolding rod is connected to one end of the support rod at the beginning of the scissor lift structure. One end of the tread rod at the beginning of the scissor lift structure is connected to the intersection of the first rotating segment and the second rotating segment. The second driving member is connected to the unfolding rod.

[0018] The pedals are connected between the two spaced-apart unfolding rods and between the two spaced-apart corresponding tread rods.

[0019] In some embodiments, the number of scissor lift members is three; and / or, the second drive member is connected to the middle of the deploying rod.

[0020] In some embodiments, the folding assembly further includes a tail rod, a tail support rod, and a buffer block. One end of the tail rod is connected to one end of the tail support rod, and the other end of the tail rod is connected to the support rod at the tail end of the scissor structure.

[0033] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0034] In the description of this application, the orientation or positional relationship of "upper," "lower," "inner," "outer," and "rail vehicle width direction" is based on the appendix. Figures 1-3 The orientations or positional relationships shown are intended only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] In the description of this application, the rail vehicles are mainly based on urban rail vehicles as the technical background for the implementation and description of the implementation, and the specific type of rail vehicles is not limited.

[0036] One embodiment of this application provides a rail vehicle, see [link to previous document]. Figure 1 The rail vehicle includes a base frame 200 and a mounting beam frame 300. The base frame 200 includes a floor 21 and side beams 22. The floor 21 is provided with side beams 22 at both ends along the width direction of the rail vehicle. The side beams 22 are arranged substantially perpendicular to the floor 21, and the lower end of the side beams 22 protrudes from the lower surface of the floor 21.

[0037] The mounting beam 300 is mounted on the underframe 200 of the rail vehicle. Specifically, the two ends of the mounting beam 300 are connected to the side beams 22 at both ends of the floor 21, and the mounting beam 300 is located below the floor 21.

[0038] One embodiment of this application provides an evacuation device 100 for rail vehicles, see [link to previous document]. Figure 1 , Figure 2 and Figure 3The evacuation device 100 includes a fixing component 11, an evacuation staircase 12, a first drive component 13, and a second drive component 14.

[0039] The fixing component 11 is used to connect the mounting beam 300 of the rail vehicle, which is located on the underframe 200 of the rail vehicle; the evacuation staircase 12 has an unfolded state and a folded state, and is connected to the fixing component 11 and can rotate relative to the fixing component 11.

[0040] Understandably, when the evacuation staircase 12 is in the deployed state, it allows passengers to enter and exit the rail vehicle, thus facilitating passenger evacuation. The evacuation device 100 is connected to the mounting beam 300 via a fixing component 11 to secure it to the rail vehicle. For example, the evacuation device 100 may be installed on one side of the mounting beam 300 near the side beam 22, or it may be installed on both sides of the mounting beam 300 near the side beam 22. Thus, according to actual passenger evacuation needs, the rail vehicle can achieve passenger evacuation from one side or both sides simultaneously via the evacuation staircase 12, improving evacuation efficiency and ensuring passenger safety.

[0041] The first driving member 13 connects the fixing component 11 and the evacuation staircase 12, and is used to drive the evacuation staircase 12 to rotate relative to the fixing component 11. The second driving member 14 is disposed on the evacuation staircase 12, and is used to drive the evacuation staircase 12 to be in an unfolded state or a folded state.

[0042] Understandably, when the rail vehicle needs to evacuate passengers, the first drive member 13 can drive the evacuation staircase 12 to extend from below the underframe 200 to the outside of the rail vehicle, and the second drive member 14 can drive the evacuation staircase 12 to be in an unfolded state. Thus, the evacuation staircase 12 can connect to the external platform or the ground, allowing passengers to enter and exit the rail vehicle via the evacuation staircase 12. After the rail vehicle has completed evacuation, the second drive member 14 can drive the evacuation staircase 12 to be folded, reducing the overall size of the evacuation staircase 12 and the space required to accommodate it. The first drive member 13 can drive the evacuation staircase 12 to retract from the outside of the rail vehicle back below the underframe 200, making full use of the space under the rail vehicle's underframe 200. In this way, the first drive member 13 and the second drive member 14 can realize the unfolding or folding of the evacuation staircase 12, which is convenient to operate and enables rapid evacuation.

[0043] The specific order in which the first driving member 13 and the second driving member 14 control and drive the evacuation staircase 12 is not limited. In some embodiments, while the first driving member 13 drives the evacuation staircase 12 to rotate relative to the fixed component 11, the second driving member 14 can also drive the evacuation staircase 12 to be in an unfolded or folded state. In this way, the evacuation staircase 12 can be quickly unfolded to improve evacuation efficiency. In other embodiments, when the rail vehicle needs to evacuate people, the first driving member 13 first drives the evacuation staircase 12 to extend from below the underframe 200 to the outside of the rail vehicle, and then the second driving member 14 drives the evacuation staircase 12 to be in an unfolded state; after the rail vehicle has completed the evacuation, the second driving member 14 first drives the evacuation staircase 12 to be in a folded state, and then the first driving member 13 can drive the evacuation staircase 12 to be retracted from the outside of the rail vehicle back to below the underframe 200. In this way, the first drive member 13 and the second drive member 14 drive the evacuation staircase 12 in stages, which can avoid mutual interference between the evacuation staircase 12 and the equipment or structure under the base frame 200 during the switching between the folded state and the unfolded state.

[0044] In some embodiments, see Figure 2 The fixing component 11 includes a fixing bracket 111 and a lifting beam 112. The first driving member 13 and the lifting beam 112 are respectively connected to the opposite ends of the fixing bracket 111. The middle position of the lifting beam 112 is recessed upward to form a lifting section 1121 and an installation section 1122 connected to both ends of the lifting section 1121. The lifting section 1121 is used to connect the evacuation staircase 12, and the installation section 1122 is used to connect the fixing bracket 111.

[0045] The connection point between the first driving component 13 and the fixed bracket 111 is the first connection point 11a, and the connection point between the evacuation staircase 12 and the lifting beam 112 is the second connection point 11b. The first connection point 11a and the second connection point 11b are located at opposite ends of the fixed bracket 111. It can be understood that if the evacuation staircase 12 needs to be retracted from the outside of the rail vehicle to the underframe 200 or extended from below the underframe 200 to the outside of the rail vehicle, then the second connection point 11b is closer to the outside of the rail vehicle, and the first connection point 11a is farther from the outside of the rail vehicle, that is, the first connection point 11a is located on the inside of the rail vehicle, and the direction of the line connecting the opposite ends of the fixed bracket 111 is the width direction of the rail vehicle. Thus, the first drive member 13 is connected to the evacuation staircase 12 along the width direction of the rail vehicle. The first drive member 13 can drive the evacuation staircase 12 to rotate along the width direction of the rail vehicle so that the evacuation staircase 12 moves closer to or away from the first connection point 11a, so that the evacuation staircase 12 is retracted from the outside of the rail vehicle to the underframe 200 or extends from below the underframe 200 to the outside of the rail vehicle.

[0046] When the evacuation staircase 12 is in the deployed state, passengers stepping on the evacuation staircase 12 will cause the evacuation staircase 12 to bear a vertical downward gravity. The direction of gravity is perpendicular to the width direction of the rail vehicle. Therefore, the gravity on the evacuation staircase 12 will not be transmitted to the first drive component 13, thereby ensuring the safety of the first drive component 13, reducing the probability of damage to the first drive component 13 due to force, and extending the service life of the first drive component 13.

[0047] The middle position of the lifting beam 112 is recessed upward, which can increase the vertical space between the lifting section 1121 and the bottom of the rail vehicle, so as to facilitate the installation of the evacuation staircase 12 and allow the evacuation staircase 12 to have more room to move when it rotates relative to the lifting beam 112.

[0048] In some embodiments, see Figure 2 The lifting beam 112 has a flange 1123 on its side, located on the side of the lifting beam 112 away from the fixed support 111. For example, flanges 1223 are provided on both sides of the lifting beam 112 perpendicular to the width direction of the rail vehicle, and the flanges 1223 extend from the installation section 1122 at one end to the lifting section 1121 at the other end. In this way, the flanges 1123 will not interfere with the evacuation staircase 12 below the lifting beam 112, and can enhance the structural strength of the lifting beam 112, so that the lifting beam 112 can better bear the weight transmitted by the evacuation staircase 12, thereby improving the safety of the evacuation device 100.

[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The evacuation staircase 12 includes a rotating component 121 and a staircase body. The rotating component 121 is connected to the fixing component 11 and the staircase body. A first driving component 13 is connected to the fixing component 11 and the rotating component 121, and a second driving component 14 is connected to the rotating component 121 and the staircase body.

[0050] It is understood that the first driving member 13 drives the rotating member 121 to rotate relative to the fixed component 11, thereby causing the stair body to extend out of the outside of the rail vehicle or retract under the base frame 200 of the rail vehicle. The second driving member 14 drives the stair body to switch the evacuation staircase 12 between the unfolded state and the folded state.

[0051] In some embodiments, see Figure 1 , Figure 2 and Figure 3 There are two rotating parts 121, two first driving parts 13 and two second driving parts 14. The two rotating parts 121, two first driving parts 13 and two second driving parts 14 are arranged at intervals. The stair body is connected to the two rotating parts 121.

[0052] Understandably, the two rotating parts 121 are connected to opposite sides of the staircase body, the two first driving parts 13 are connected to the two rotating parts 121, and the two second driving parts 14 are connected to the two rotating parts 121 and the opposite sides of the staircase body. In this way, the two rotating parts 121 can achieve force balance on opposite sides of the staircase body, making the structure of the evacuation staircase 12 more stable and achieving better load-bearing capacity. The two first driving parts 13 and the two second driving parts 14 can better drive the evacuation staircase 12, enabling its rapid deployment and retraction, thereby improving evacuation efficiency.

[0053] Each rotating component 121 includes a first rotating segment 1211 and a second rotating segment 1212 arranged at an angle. The first rotating segment 1211 is connected to the fixing component 11, and the second rotating segment 1212 is connected to the stair body. The first driving component 13 and the second driving component 14 on each side are respectively connected to the intersection of the first rotating segment 1211 and the second rotating segment 1212 of the rotating component 121 on the corresponding side.

[0054] It is understood that the intersection of the first rotating segment 1211 and the second rotating segment 1212 of the rotating component 121 is the intersection point of the rotating component 121. This intersection point refers only to the macroscopic positional relationship and should be understood as an area with a certain size range. One end of the second driving component 14 on each side is connected to the intersection point of the rotating component 121 on the corresponding side, and the other end is connected to the corresponding side of the stair body. In this way, the two second driving components 14 can simultaneously apply force to the opposite sides of the stair body to balance the forces on the opposite sides of the stair body, so as to better realize the switching between the unfolded state and the folded state.

[0055] The specific direction of the opening formed by the included angle between the first rotating segment 1211 and the second rotating segment 1212 is not limited. See some embodiments for details. Figure 1 , Figure 2 and Figure 3 The opening formed by the angle between the first rotating segment 1211 and the second rotating segment 1212 opens upwards.

[0056] Understandably, the lower end of the second rotating segment 1212 intersects with the lower end of the first rotating segment 1211, the upper end of the first rotating segment 1211 is connected to the fixing component 11, and the upper end of the second rotating segment 1212 is connected to the stair body. One end of the second driving member 14 is connected to the intersection point of the rotating member 121, and the other end is connected upward to the stair body. Specifically, in one case, the opposite ends of the second driving member 14 are vertically connected to the intersection point of the rotating member 121 and the stair body; in another case, one end of the second driving member 14 is connected to the intersection point of the rotating member 121, and the other end is inclined upward to connect to the stair body. Thus, when the evacuation staircase 12 is in the unfolded state, the weight generated when passengers step on the evacuation staircase 12 will be transferred to the second driving member 14 through the evacuation staircase 12, thereby enhancing the load-bearing capacity of the evacuation staircase 12.

[0057] In some embodiments where the included angle between the first rotating segment 1211 and the second rotating segment 1212 opens upwards, see [reference needed]. Figure 1 , Figure 2 and Figure 3 The second drive component 14 is telescopic, such as a telescopic cylinder. When the evacuation staircase 12 is in the unfolded state, the second drive component 14 is in the retracted state; when the evacuation staircase 12 is in the folded state, the second drive component 14 is in the extended state.

[0058] Understandably, the second drive member 14 has a telescopic extension rod 141. During the process of the second drive member 14 moving from a retracted state to an extended state, the second drive member 14 can control the extension rod 141 to extend, thereby driving the evacuation staircase 12 from a folded state to an unfolded state. Conversely, during the process of the second drive member 14 moving from an extended state to a retracted state, the second drive member 14 can control the extension rod 141 to retract, thereby driving the evacuation staircase 12 from an unfolded state to a folded state. Thus, when the second drive member 14 is in the retracted state, the evacuation staircase 12 is in the unfolded state. The gravity generated when passengers step on the evacuation staircase 12 will press down on the extension rod 141, causing it to retract further. The retraction of the extension rod 141 facilitates the unfolding of the evacuation staircase 12, thereby reducing the probability of the evacuation staircase 12 failing to fold due to the second drive member 14 rebounding, and thus improving the safety of the evacuation device 100.

[0059] It should be noted that when the second drive member 14 is in the retracted state, the extension rod 141 of the second drive member 14 is retracted to the limit state, and the components of the second drive member 14 form a relatively stable state and have a certain load-bearing capacity. In this way, the second drive member 14 can work together with the evacuation staircase 12 to bear the weight of the passengers, so as to play a better evacuation role.

[0060] In some embodiments, see Figure 1 , Figure 2 and Figure 3The first rotating segment 1211 and the second rotating segment 1212 of the rotating member 121 are provided with a connecting segment 1213 extending away from the first rotating segment 1211. The connecting segment 1213 is used to connect the second driving member 14.

[0061] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The staircase body includes two folding assemblies 123 spaced apart and a plurality of treads 122 disposed between the two folding assemblies 123. Each folding assembly 123 includes an unfolding rod 1231, at least one tread rod 1232 and at least one support rod 1233.

[0062] Tread rods 1232 and support rods 1233 are arranged in pairs. The middle position of each pair of tread rods 1232 is rotatably connected to the middle position of the support rod 1233 to form a scissor lift member. At least two scissor lift members are connected end to end to form a scissor lift structure. It can be understood that in the scissor lift structure, for two adjacent scissor lift members, the tail end of the support rod 1233 of one scissor lift member is connected to the head end of the tread rod 1232 of the other scissor lift member, and the tail end of the tread rod 1232 of one scissor lift member is connected to the head end of the support rod 1233 of the other scissor lift member.

[0063] One end of the unfolding rod 1231 is connected to the end of the second rotating segment 1212 away from the first rotating segment 1211, and the other end of the unfolding rod 1231 is connected to one end of the support rod 1233 at the beginning of the scissor structure. One end of the tread rod 1232 at the beginning of the scissor structure is connected to the intersection of the first rotating segment 1211 and the second rotating segment 1212. The second driving member 14 is connected to the unfolding rod 1231. A pedal 122 is connected between the two spaced-apart unfolding rods 1231 and between the two spaced-apart corresponding tread rods 1232.

[0064] It is understood that the second driving component 14 is connected to the unfolding rod 1231 and the rotating component 121 respectively. That is, the second driving component 14 is directly connected to the folding assembly 123. The second driving component 14 can directly drive the unfolding rod 1231 to apply force directly to the folding assembly 123, thereby controlling the unfolding or folding of the folding assembly 123, so that the evacuation staircase 12 can quickly complete the switching between the unfolded state and the folded state.

[0065] The specific number of scissor lift components is not limited. See some embodiments for details. Figure 1 , Figure 2 and Figure 3 The number of scissor lift components is three. Understandably, the specific number of scissor lift components needs to be determined based on the specific design of the rail vehicle and station platform, as well as the dimensions of the scissor lift components themselves.

[0066] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The second driving member 14 is connected to the middle part of the unfolding rod 1231. In this way, the second driving member 14 applies a force to the middle part of the unfolding rod 1231, which can make the force on the unfolding rod 1231 balanced. The force on the unfolding rod 1231 is evenly transmitted from the middle to both ends of the unfolding rod 1231, and then to the entire folding assembly 123, so as to quickly realize the unfolding or folding of the folding assembly 123.

[0067] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The folding assembly 123 also includes a tail rod 1234, a tail support rod 1235, and a buffer block 1236. One end of the tail rod 1234 is connected to one end of the tail support rod 1235, and the other end of the tail rod 1234 is connected to the support rod 1233 at the tail end of the scissor structure. The other end of the tail support rod 1235 is connected to the tread rod 1232 at the tail end of the scissor structure. The buffer block 1236 is located at the end of the tail rod 1234 near the tail support rod 1235, and the buffer block 1236 protrudes from the side of the tail rod 1234 away from the tread rod 1232.

[0068] Understandably, the buffer block 1236 is used to abut against the bottom surface or platform to prevent the tail rod 1234 and tail support rod 1235 of the folding assembly 123 from directly contacting the ground and causing damage, and to provide cushioning force to ensure the stability of the evacuation staircase 12.

[0069] In some embodiments, see Figure 1 , Figure 2 and Figure 3 When the evacuation staircase 12 is in the deployed state, the steps 122 are tilted downwards toward the side closest to the fixing component 11. In this way, when passengers walk down the evacuation staircase 12, the steps 122 help to mitigate the inertial force of the passengers tilting downwards, thereby reducing the chance of passengers falling and getting injured.

[0070] When the evacuation staircase 12 is in the unfolded state, the treads 122 tilt downwards toward the side closer to the fixing component 11 at an angle that is not limited. In some embodiments, when the evacuation staircase 12 is in the unfolded state, the angle at which the treads 122 tilt downwards toward the side closer to the fixing component 11 ranges from 0° to 7°, for example: 0°, 1°, 2°, 3°, 4°, 5°, 6°, and 7°.

For those skilled in the art, this application can have various modifications and variations.
