[0032] 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.

[0033] In the description of this application, the orientation or positional relationship of "upper," "lower," "inner," "outer," "rail vehicle width direction," "skirt length direction," and "skirt width direction" is based on the appendix. Figures 1-6 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.

[0034] In the description of this application, the specific type of rail vehicle is not limited. The following is mainly based on urban rail vehicles as the technical background for the implementation examples and the writing of the examples.

[0035] This application provides a rail vehicle, see [link to relevant documentation] Figure 1 and Figure 2 The rail vehicle includes a base frame 2 and an evacuation device 3.

[0036] The base frame 2 includes a floor 21 and side beams 22. Side beams 22 are respectively provided at both ends of the floor 21 along the width direction of the rail vehicle. The side beams 22 are generally perpendicular to the floor 21, and the lower end of the side beams 22 protrudes from the lower surface of the floor 21 for installing evacuation devices 3.

[0037] The evacuation device 3 includes an evacuation staircase 32 and an evacuation beam frame 31. The evacuation beam frame 31 is connected to the base frame 2. For example, both ends of the evacuation beam frame 31 are connected to the lower protruding parts of the side beams 22 on both sides of the floor 21. The evacuation staircase 32 is mounted on the evacuation beam frame 31. The evacuation staircase 32 is fixed to the bottom of the base frame 2 via the evacuation beam frame 31, and the evacuation staircase 32 has an open state and a closed state. In the open state, the evacuation staircase 32 can extend from the bottom of the base frame 2 to the outside of the rail vehicle and connect with the external platform or the ground, allowing passengers to enter and exit the rail vehicle via the evacuation staircase 32, thereby achieving the function of evacuating people. In the closed state, the evacuation staircase 32 retracts from the outside of the rail vehicle to the bottom of the base frame 2 to make full use of the space under the base frame 2 of the rail vehicle.

[0038] In some embodiments (not shown), the evacuation beam connects the side beams and evacuation stairs at both ends along the width direction of the rail vehicle. According to the actual needs of passenger evacuation, the rail vehicle can simultaneously evacuate passengers from both sides of the vehicle through the evacuation stairs, so as to improve evacuation efficiency and ensure passenger safety.

[0039] Another aspect of this application provides a skirt structure 1 for rail vehicles, see [link to relevant documentation]. Figures 1-5 The skirt structure 1 includes a skirt 15, a fixing component 11, a supporting component 12, and a first driving component 13.

[0040] The fixing component 11 is used to connect the evacuation beam 31 of the evacuation device 3 of the rail vehicle, and the evacuation beam 31 is provided on the underframe 2 of the rail vehicle; the support component 12 is connected to the skirt 15 and the fixing component 11 respectively, the support component 12 can rotate relative to the fixing component 11, and the support component 12 has a receiving space 11a.

[0041] Understandably, the skirt structure 1 is connected to the evacuation beam 31 via the fixing component 11 and is mounted on the rail vehicle. The skirt 15 is located near the outside of the rail vehicle and can connect with the underframe 2. The accommodating space 11a of the support component 12 can provide space for the evacuation staircase 32. The support component 12 rotates relative to the fixing component 11 to cause the skirt 15 to separate from or connect with the underframe 2.

[0042] The first driving component 13 is connected to the fixed component 11 and the support component 12 respectively. The first driving component 13 is used to drive the support component 12 to rotate relative to the fixed component 11 so that the skirt 15 is in the unfolded state or in the retracted state.

[0043] When the skirt panel 15 is in the retracted state, the receiving space 11a is used to accommodate the evacuation staircase 32 of the evacuation device 3. That is, the first driving member 13 drives the support assembly 12 to rotate relative to the fixed assembly 11, so that the skirt panel 15 is connected to the base frame 2, and the evacuation staircase 32 is retracted into the receiving space 11a. The skirt panel 15 is located on the side of the evacuation staircase 32 closer to the outside of the rail vehicle, so as to protect and shield the evacuation staircase 32.

[0044] When the skirt panel 15 is in the deployed state, the evacuation staircase 32 can extend from the gap between the skirt panel 15 and the base frame 2. That is, the first drive member 13 drives the support assembly 12 to rotate relative to the fixed assembly 11, so that the skirt panel 15 is separated from the base frame 2, the accommodating space 11a is connected to the outside of the rail vehicle, and the evacuation staircase 32 can extend from the gap between the skirt panel 15 and the base frame 2 to realize the evacuation function.

[0045] The specific design of the first driving element 13 is not limited. See also [reference needed] for some embodiments. Figure 3 and Figure 4 The first driving component 13 is a telescopic cylinder.

[0046] In some embodiments, see Figure 1 and Figure 2 The evacuation device 3 also includes a second drive member 33 and a third drive member 34. The second drive member 33 is connected to the evacuation staircase 32 and the fixing assembly 11, and is used to drive the evacuation staircase 32 to extend from under the base frame 2 to the outside of the rail vehicle, or to drive the evacuation staircase 32 to retract from the outside of the rail vehicle to under the base frame 2. The third drive member 34 is disposed on the evacuation staircase 32 and is used to drive the evacuation staircase 32 to extend for passenger evacuation, or to drive the evacuation staircase 32 to compress to reduce the space required for its placement. In this way, the second drive member 33 and the third drive member 34 work together to switch the evacuation staircase 32 to an open or closed state as needed, thereby achieving the function of evacuating people and improving the safety of the rail vehicle.

[0047] The specific design of the second driving element 33 is not limited. See also the following embodiments: Figure 1 and Figure 2 The second driving component 33 is a telescopic cylinder.

[0048] The specific design of the third drive element 34 is not limited. See also the following embodiments: Figure 1 and Figure 2 The third driving component 34 is a telescopic cylinder.

[0049] In some embodiments, see Figure 1 and Figure 2The fixing component 11 of the skirt structure 1 is connected to one end of the evacuation beam 31 near the side beam 22, so that the skirt 15 is in contact with the lower end of the side beam 22 when it is in the retracted state. The surface of the skirt 15 near the outer side of the rail vehicle is flush with the surface of the side beam 22 near the outer side of the rail vehicle. In this way, the skirt 15 and the side beam 22 can form a smooth transition, which can play a role in beautifying the rail vehicle.

[0050] In some embodiments, see Figure 3 and Figure 4 The support assembly 12 includes two spaced-apart support frames 121. One end of each support frame 121 is connected to the fixing assembly 11, and the other end is connected to both ends of the skirt 15 along the length direction. A receiving space 11a is formed between the two support frames 121.

[0051] The support frame 121 connects the two ends of the skirt panel 15 along its length, enabling the skirt panel 15 to be evenly stressed along its length, thus achieving a stable connection between the support frame 121 and the skirt panel 15 and ensuring the overall structural stability of the skirt panel structure 1. Furthermore, the evacuation staircase 32 is placed within the accommodating space, and the support frames 121 on both sides provide protection for the evacuation staircase 32.

[0052] In some embodiments, see Figure 3 and Figure 4 The support frame 121 includes a first support rod 1211 and a second support rod 1212. One end of the first support rod 1211 and one end of the second support rod 1212 are connected at an angle and are rotatably connected to the fixed assembly 11. The other end of the first support rod 1211 and the other end of the second support rod 1212 are respectively connected to the two ends of the skirt 15 along the width direction. When the skirt 15 is in the retracted state, the first support rod 1211 is located above the second support rod 1212.

[0053] The first support rod 1211 and the second support rod 1212 ensure that the skirt panel 15 is subjected to uniform force at both ends along its width, thereby achieving a stable connection between the support frame 121 and the skirt panel 15 and ensuring the overall structural stability of the skirt panel structure 1. Furthermore, the first support rod 1211 and the second support rod 1212 are connected at an angle, forming a triangular structure together with the skirt panel 15, further enhancing the stability of the connection between the support frame 121 and the skirt panel 15.

[0054] The specific connection position between the first driving component 13 and the support frame 121 is not limited.

[0055] In some embodiments, not illustrated, the first drive member is connected to the first support rod. For example, the connection point between the first drive member and the fixing component may be located outside or inside the connection point between the support frame and the fixing component.

[0056] In other embodiments, see Figure 1, Figure 2 and Figure 4 The first driving member 13 is connected to the second support rod 1212. It can be understood that the connection point between the support assembly 12 and the fixing assembly 11 is the first connection point 301, and the first driving member 13 is used to control the rotation of the support assembly 12 around the first connection point 301. The connection point between the first driving member 13 and the fixing assembly 11 can be located outside or inside the connection point between the support frame 121 and the fixing assembly 11.

[0057] In some embodiments, see Figure 1 and Figure 2 The skirt structure 1 also includes a locking member 14 for restricting the rotation of the support assembly 12 relative to the fixed assembly 11 when the skirt 15 is in the retracted state.

[0058] It is understandable that the support component 12 is mounted on the fixed component 11 and then fixed by the locking component 14. In this way, the support component 12 can be stably connected to the fixed component 11 in the retracted state, thereby reducing the probability of the skirt structure 1 falling off and being damaged during the operation of the rail vehicle.

[0059] The installation location and specific style of the locking element 14 are not limited. For example, the locking element 14 can be installed on a fixed skirt plate adjacent to the skirt plate structure of the embodiment of this application on a rail vehicle. The locking element 14 is similar to a door bolt and can be a drive shaft. In some embodiments, see [link to relevant documentation]. Figure 3 and Figure 4 The locking element 14 is a rotary cylinder.

[0060] In some embodiments, see Figure 3 and Figure 4 The locking member 14 is used to lock into the first support rod 1211 so that when the skirt 15 is in the retracted state, the first support rod 1211 is in a horizontal position. For example, the locking member 14 is a rotary cylinder, and the end of the locking member 14 forms an inverted "T" shape. The first support rod 1211 has a groove to accommodate the inverted "T" shaped end of the locking member 14, and the upper part of the groove is a straight "I" shaped opening. The inverted "T" shaped end of the rotary cylinder is inserted into the straight "I" shaped groove on the first support rod 1211, and then the rotary cylinder is rotated to lock.

[0061] In some embodiments, see Figure 1 and Figure 2 The locking member 14 is disposed on the fixed component 11. Along the width direction of the rail vehicle, the connection point between the support component 12 and the fixed component 11 is located between the connection point between the first drive component 13 and the fixed component 11 and the connection point between the locking member 14 and the fixed component 11.

[0062] Understandably, when the skirt panel 15 is in the retracted state, it abuts against the lower end of the side beam 22. The locking member 14 is used to lock the connection with the first support rod 1211, and the first support rod 1211 is in a horizontal position. In this case, the locking member 14 is located on the side of the first connection point 301 closer to the outside of the rail vehicle, and the corresponding first drive member 13 is located on the side of the first connection point 301 closer to the inside of the rail vehicle. In this way, the arrangement of the first drive member 13 and the locking member 14 can make full use of the structural space required by the fixing assembly 11, making the skirt panel structure 1 compact.

[0063] In some embodiments, see Figure 3 and Figure 4 The support frame 121 also includes a third support rod 1213, which is connected to the end of the first support rod 1211 away from the fixing component 11 and the end of the second support rod 1212 away from the fixing component 11. The third support rod 1213 can form a triangular structure together with the first support rod 1211 and the second support rod 1212 to enhance the stability of the support frame 121 itself.

[0064] In some embodiments, the connection point between the first drive member 13 and the second support rod 1212 is located within 1 / 3 to 1 / 2 of the overall length of the second support rod 1212 near the end of the fixing component 11.

[0065] It is understood that the overall length L of the second support rod 1212 refers to the distance between the end of the second support rod 1212 connected to the fixing assembly 11 and the end of the second support rod 1212 connected to the skirt plate 15. The connection point between the first driving member 13 and the second support rod 1212 is the second connection point 121a.

[0066] The second connection point 121a is located within 1 / 3 to 1 / 2 of the total length L of the second support rod 1212. Under the condition of satisfying the force of the first driving member 13, it occupies less space. The rotation stroke of the first driving member 13 driving the support assembly 12 to rotate around the first connection point 301 is short, which can realize the rapid rotation of the support assembly 12, thereby realizing the rapid deployment or retraction of the skirt 15.

[0067] It should be noted that the selection of the specific location of the second connection point 121a requires comprehensive consideration of various factors, such as the overall center of gravity of the support assembly 12 and the skirt 15 after assembly, and the rotational stroke of the first driving member 13 driving the support assembly 12. Among these considerations, the overall center of gravity of the support assembly 12 and the skirt 15 after assembly is to reduce the driving force required for the first driving member 13 to drive the support assembly 12 to rotate, and the rotational stroke of the first driving member 13 driving the support assembly 12 to rotate is to achieve rapid rotation of the support assembly 12 with a smaller rotational stroke.

[0068] The specific location of the second connection point 121a is not limited. For example, the second connection point 121a may be located at 1 / 3, 5 / 12, or 1 / 2 of the total length L of the second support rod 1212 near the end of the fixing component 11.

[0069] Specifically, see Figure 6 In this application, the second connection point 121a is located at 1 / 2 of the total length L of the second support rod 1212.

[0070] In some embodiments, see Figure 3 and Figure 4 The fixing component 11 includes at least two fixing beams 111, which are arranged parallel to each other along their extension direction perpendicular to themselves, and each fixing beam 111 is connected to a support frame 121.

[0071] In some embodiments, see Figure 5 The fixing assembly 11 also includes a fixing longitudinal beam 113, with fixing crossbeams 111 connected to both ends of the fixing longitudinal beam 113 along its extension direction. The fixing longitudinal beam 113 and the fixing crossbeams 111 together form a stable frame structure to further improve the stability of the skirt structure 1. Furthermore, both ends of the fixing longitudinal beam 113 are connected to the evacuation beam frame 31 to connect the skirt structure 1 to the rail vehicle.

[0072] In some embodiments, see Figure 3 and Figure 4 The fixed longitudinal beam 113 is located at the end of the fixed crossbeam 111 near the inner side of the rail vehicle. The evacuation device 3 beam frame includes an evacuation longitudinal beam 312 and two evacuation crossbeams 311. The two evacuation crossbeams 311 are arranged parallel to each other along their extension direction perpendicular to themselves, and their two ends along the extension direction are respectively connected to the side beam 22. The two ends of the fixed longitudinal beam 113 are respectively connected to the two evacuation crossbeams 311, so that one end of the fixing component 11 is fixed to the evacuation beam frame 31. The two ends of the evacuation longitudinal beam 312 along the extension direction are respectively connected to the two ends of the fixed crossbeams 111 near the outer side of the rail vehicle, and the two ends of the evacuation longitudinal beam 312 along the extension direction are respectively connected to the two evacuation beam frames 31. In this way, the evacuation longitudinal beam 312 can achieve a stable connection between the fixing component 11 and the evacuation beam frame 31, thereby improving the stability of the connection between the skirt structure 1 and the rail vehicle.

[0073] In some embodiments, see Figure 5 The evacuation longitudinal beam 312 is located above the fixing component 11. The two ends of the evacuation longitudinal beam 312 are bent downward along the extension direction to form a relief groove, and the groove opening faces the receiving space 11a.

[0074] It is understood that the receiving space 11a formed by the support component 12 is located below the fixed component 11, and the evacuation staircase 32 set in the receiving space 11a needs to extend out of the outside of the rail vehicle. The clearance groove of the evacuation longitudinal beam 312 can increase the size of the receiving space 11a in the vertical direction, thereby avoiding interference between the evacuation staircase 32 and the evacuation longitudinal beam 312 when the evacuation staircase 32 extends out of the outside of the rail vehicle, so that the evacuation staircase 32 has a larger activity space.

[0075] In some embodiments, see Figure 1 and Figure 2 The first driving member 13 and the locking member 14 are respectively located on both sides of the first connection point 301 along the extension direction of the fixed crossbeam 111.

[0076] The first driving component 13, the locking component 14, and the first connection point 301 are sequentially arranged on the fixed crossbeam 111 along its extension direction. The arrangement of the first driving component 13 and the locking component 14 can fully utilize the structural space required by the fixed crossbeam 111, resulting in a compact structure. Furthermore, the first driving component 13 and the locking component 14 respectively control the rotation and fixation of one support frame 121, making the control operation clear and direct, which is beneficial to improving control efficiency.

[0077] In some embodiments, see Figure 3 and Figure 4 The fixing component 11 includes a connecting seat 112 disposed on the fixing beam 111, and a support component 12 rotatably disposed on the connecting seat 112. The connection point between the support component 12 and the connecting seat 112 is located below the fixing beam 111. Thus, the arrangement of the support component 12 and the connecting seat 112 fully utilizes the structural space required by the fixing component 11, making the skirt structure 1 compact. When the locking member 14 is disposed on the fixing component 11 and the skirt 15 is in the retracted state, the first support rod 1211 is in a horizontal position, and the support component 12 is connected to the connecting seat 112, facilitating the installation of the locking member 14 on the fixing component 11 to lock the support component 12.
