[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0060] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0061] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] In the related art, the escape ladders equipped on rail transit vehicles can only be deployed on straight tracks or large-radius curves. For small-radius and narrow tracks, the adaptability of the escape ladders is poor. When deployed, the escape ladders will interfere with the bosses on both sides of the track and cannot be effectively deployed.

[0063] To solve the above problems, please refer to Figure 1 The present application proposes a rail transit vehicle 2000, which can be a subway, a high-speed railway, or a cloud rail, and the present application does not limit this. The rail transit vehicle 2000 includes a vehicle body 2100 and an escape device 1000.

[0064] Please refer to Figure 2 The car body 2100 serves as a supporting frame of the rail vehicle 2000, and is used to support and connect other structures or assemblies of the rail vehicle 2000. The car body 2100 is provided with a limiting groove 2110. The setting of the limiting groove 2110 can, on the one hand, provide avoidance for the movement of the escape device 1000, so as to facilitate the folding and unfolding of the escape device 1000. On the other hand, when the escape device 1000 is in a folded state, the limiting groove 2110 can provide support for the escape device 1000, so as to facilitate the folding of the escape device 1000.

[0065] Please refer to Figure 3 and Figure 4 The escape device 1000 is arranged on the vehicle body 2100. When the rail transit vehicle 2000 operates normally, the escape device 1000 is stored in the vehicle body 2100. When the rail transit vehicle 2000 encounters a failure or other emergency, the escape device 1000 is lowered to evacuate the passengers in the rail transit vehicle 2000.

[0066] The escape device 1000 includes an escape ladder 1 and a rotating disk 2. The rotating disk 2 is arranged on the vehicle body 2100 and can rotate around a first axis. The escape ladder 1 is arranged on the rotating disk 2. The technical solution of the present application is to rotate the rotating disk 2 on the vehicle body 2100, and then arrange the escape ladder 1 on the rotating disk 2. In this way, when the rail vehicle 2000 fails or encounters an emergency at a small radius track, the passengers can rotate the escape ladder 1 to find a suitable place to place the escape ladder 1 in the track, thereby solving the problem that the escape ladder 1 cannot be deployed at a small radius curve, and expanding the scope of application of the escape device 1000.

[0067] It can be understood that in this embodiment, the escape ladder 1 can be fixed on the rotating disk 2, or can be rotatably arranged on the rotating disk 2, and the present application does not limit this. In one possible implementation of the present application, the escape ladder 1 is rotatably arranged on the rotating disk 2, and can rotate around the second axis. When the rail vehicle 2000 encounters a fault or other emergency, the escape ladder 1 can be flipped out of the car body 2100 along the second axis to form an escape passage to evacuate passengers. When the rail vehicle 2000 operates normally, the escape ladder 1 can be folded along the second axis to be stored in the car body 2100, thereby avoiding the escape ladder 1 from affecting the normal operation of the rail vehicle 2000. The second axis and the first axis are two intersecting axes, and the first axis and the second axis can intersect at 30°, 60°, or perpendicularly, and the present application does not limit this. In one possible implementation of the present application, the second axis and the first axis are two perpendicularly intersecting axes, so as to optimize the structure of the escape ladder 1 and improve the convenience of using the escape ladder 1.

[0068] Please refer to Figure 5 The rotating disk 2 includes a disk body 21 and a limiting portion 22. The disk body 21 is the main body of the rotating disk 2 and is used to support and connect various parts of the rotating disk 2. The limiting portion 22 is arranged on the side of the disk body 21 facing the vehicle body, and the limiting portion 22 is used to extend into the limiting groove of the vehicle body. The limiting portion 22 can be connected to the rotating disk 2 by threads, can be riveted to the rotating disk 2 by rivets, or can be welded to the rotating disk 2 by a welding machine, and this application does not limit this. The limiting portion 22 can move in the limiting groove 2110 driven by the rotating disk 2. When the rotating disk 2 rotates to a preset angle, the limiting portion 22 contacts the side of the limiting groove 2110, thereby preventing the rotating disk 2 from continuing to rotate. In this way, a limit is provided for the rotation of the rotating disk 2. The designer of the rail transit vehicle 2000 can set the preset angle of the rotating disk 2 according to the track conditions of the current rail transit vehicle 2000, thereby reducing the possibility of passengers over-operating the escape ladder 1 and improving the safety of the escape device 1000.

[0069] The escape ladder 1 can be arranged on the limit portion 22 or on the rotating disk 2, and the present application does not limit this. In one embodiment of the present application, the escape ladder 1 is arranged on the limit portion 22 and can rotate around the second axis under the support of the limit portion 22. The limit portion 22 can provide an installation point for the setting of the escape ladder 1, thereby simplifying the installation process of the escape ladder 1 and improving the stability of the installation of the escape ladder 1 on the rotating disk 2.

[0070] The rotating disk also includes a support portion 23, which is arranged on the limiting portion 22. The support portion 23 can be connected to the limiting portion 22 by threads, can be riveted to the limiting portion 22 by rivets, or can be welded to the limiting portion 22 by a welding machine, and this application does not limit this. The support portion 23 is mounted on the vehicle body 2100 through the limiting portion 22, and the lower end surface of the support portion 23 is in contact with the upper end surface of the vehicle body 2100. The escape ladder 1 is arranged on the support portion 23 and can rotate around the second axis under the support of the support portion 23. In this way, when the passengers step down on the escape ladder 1, the support portion 23 can provide support for the escape ladder 1 and distribute the pressure of the passengers on the escape ladder 1 to the vehicle body 2100, thereby improving the support capacity of the escape ladder 1 for the passengers, improving the stability of the support of the escape ladder 1, and extending the service life of the escape ladder 1.

[0071] In one possible implementation mode of the present application, the support portion 23 is configured using square steel. Thus, while providing support for the escape ladder 1 , the weight of the support portion 23 is reduced, the load-bearing capacity of the vehicle body 2100 is reduced, and the service life of the vehicle body 2100 is extended.

[0072] Please refer to Figures 4 to 6 The escape device 1000 also includes a locking mechanism 3, which is used to limit the rotation of the rotating disk 2. The structure of the locking mechanism 3 can be various. In one embodiment of the present application, the locking mechanism 3 includes: a locking block 31 and a locking rod 32. The locking block 31 is arranged on the rotating disk 2, and the locking block 31 is provided with a locking hole 311. The locking rod 32 is arranged on the vehicle body 2100, and the locking rod 32 is used to cooperate with the locking block 31 to lock the circumferential rotation of the rotating disk 2. Specifically, the locking rod 32 includes a locking state and an unlocking state. When the rail vehicle 2000 is in a normal operating state, the locking rod 32 is in a locking state, and the locking rod 32 extends into the locking hole 311, and the rotation of the escape ladder 1 and the rotating disk 2 is locked, so as to avoid the rotation of the escape ladder 1 from affecting the operation of the rail vehicle 2000. When the rail transit vehicle 2000 breaks down or encounters other emergencies, the passengers can adjust the locking rod 32 to an unlocked state. When the locking rod 32 is in the unlocked state, the locking rod 32 is separated from the locking hole 311, the rotating disk 2 is released, and the escape ladder 1 resumes rotating.

[0073] The locking mechanism 3 also includes a driving assembly 33, which is used to drive the locking rod 32 to switch between the locked state and the unlocked state. The driving assembly 33 can be a cylinder or a linear motor, and the present application does not limit this. In one embodiment of the present application, the driving assembly 33 includes a housing 331, an elastic member 332, and an unlocking stretch. The housing 331 serves as a supporting skeleton of the driving assembly 33, and is used to support and connect other structures of the driving assembly 33. The shape of the housing 331 can be rectangular, square, or other regular or irregular shapes. The housing 331 is connected to the vehicle body 2100. The housing 331 includes a connected active cavity 3331, a first through hole 3332, and a second through hole 3333. The first end of the locking rod 32 is movably arranged in the active cavity 3331, and the second end of the locking rod 32 extends out of the housing 331 from the first through hole 3332. The elastic member 332 is sleeved outside the locking rod 32 and connected to the cavity wall of the active cavity 3331. The elastic member 332 may be a spring, a disc spring, or an elastic rubber, and this application does not impose any restrictions thereon. The unlocking pull rope 333 has a third end and a fourth end, the third end is connected to the first end, and the fourth end extends out of the housing 331 from the second through hole 3333. When the rail vehicle 2000 is in normal operation, the second end of the locking rod 32 is pushed by the elastic member 332 and extends into the locking hole 311. When the rail vehicle 2000 fails or encounters other emergencies, the passengers can compress the elastic member 332 by pulling the fourth end, and separate the second end of the locking rod 32 from the locking hole 311, thereby releasing the rotating disk 2.

[0074] Please refer to Figure 3 In order to facilitate the pulling of the fourth end of the unlocking stretch, in one embodiment of the present application, the escape device 1000 also includes a winding mechanism 4, the winding mechanism 4 includes a base, a winding disc and a driving member, the base is arranged on the vehicle body 2100, and is used to connect the vehicle body 2100 and other components of the winding mechanism 4. The shape of the base can be circular, rectangular, or other regular or irregular shapes, which is not limited in the present application. The winding disc is rotatably arranged on the vehicle body 2100, and the fourth end of the unlocking stretch is wound on the winding disc. The driving member is used to drive the winding disc to rotate to wind or release the unlocking pull rope 333. The driving member can be a rotating motor, a rotating oil cylinder, or a rotating hand wheel, which is not limited in the present application. When the rail vehicle 2000 fails or other emergencies occur, the passengers can open the winding disc by opening the driving member, and wind the unlocking pull rope 333 through the winding disc, pull the locking rod 32, and unlock the rotating disc 2.

[0075] It is understandable that, in addition to providing the locking block 31 and the locking rod 32, the rotating disk 2 can also be locked in other ways. For example, in some other possible implementations of the present application, the locking mechanism 3 can also include an electromagnet and a permanent magnet, one of which is provided on the vehicle body 2100, and the other is provided on the rotating disk 2. The locking mechanism 3 can control the fixing and releasing of the rotating disk 2 by controlling the power on and off of the electromagnet, thereby achieving the purpose of locking the rotating disk 2.

[0076] Please refer to Figures 7 to 9 The escape ladder 1 is used to establish an escape passage when a rail vehicle 2000 breaks down or encounters other emergencies, so as to facilitate the evacuation of passengers in the rail vehicle 2000. The escape ladder 1 includes a fixed ladder 11 and a movable ladder 12. The fixed ladder 11 is arranged on the rotating disk 2. The fixed ladder 11 can rotate around the second axis. The fixed ladder 11 is provided with a sliding groove 111. The sliding groove 111 is provided with an opening 112 on the side away from the rotating disk 2. The movable ladder 12 slides in the sliding groove 111. The escape ladder 1 includes a folded state and an unfolded state. When the escape ladder 1 is in the folded state, the movable ladder 12 extends from the opening 112 to the sliding groove 111 by a first preset length. When the escape ladder 1 is in the unfolded state, the movable ladder 12 extends from the opening 112 to the sliding groove 111 by a second preset length. The second preset length is greater than the first preset length. When the rail vehicle 2000 breaks down or encounters an emergency, the escape ladder 1 is in the unfolded state, and the movable ladder 12 extends out of the sliding slot 111 by a second preset length to establish an escape passage between the rail vehicle 2000 and the ground for the evacuation of passengers. When the rail vehicle 2000 is in a normal operating state, the escape ladder 1 is switched to a folded state, and the movable ladder 12 is stored in the sliding slot 111, so as to reduce the space occupied by the escape ladder 1 in the rail vehicle 2000.

[0077] The escape ladder 1 also includes a limiting column 13 and a snap-in groove 15, one of which is provided on the fixed ladder 11, and the other is provided on the movable ladder 12. When the movable ladder 12 extends a second preset distance toward the opening 112, the limiting column 13 slides into the snap-in groove 15 to prevent the movable ladder 12 from continuing to slide toward the opening 112, thereby preventing the movable ladder 12 from escaping from the sliding groove 111.

[0078] Please refer to Figure 7 and Fig.10The escape ladder 1 also includes a handrail mechanism 14, which includes a handrail rod 143, a first connecting rod 141 and a second connecting rod 142. The first connecting rod 141 has a fifth end 1411 and a sixth end 1412 that are relatively arranged, and the fifth end 1411 is rotatably connected to the fixed ladder 11. The second connecting rod 142 is spaced apart from the first connecting rod 141, and the second connecting rod 142 has a seventh end 1421 and an eighth end 1422 that are relatively arranged, and the seventh end 1421 is rotatably connected to the fixed ladder 11. The handrail rod 143 is connected between the sixth end 1412 and the eighth end 1422. When the escape ladder 1 is in an unfolded state, the handrail rod 143 can be unfolded from both sides of the escape ladder 1 under the action of the first connecting rod 141 and the second connecting rod 142 for use by passengers. When the escape ladder 1 is in a folded state, the handrail rod 143 can also be folded to both sides of the escape ladder 1 through the first connecting rod 141 and the second connecting rod 142 to save space.

[0079] The handrail bar 143, the first connecting rod 141 and the second connecting rod 142 can be made of plastic, wood or metal, and the present application does not limit this. In one embodiment of the present application, the handrail bar 143, the first connecting rod 141 and the second connecting rod 142 can be made of hard metal such as steel and iron, so as to improve the supporting effect of the handrail bar 143, the first connecting rod 141 and the second connecting rod 142 and extend the service life of the handrail bar 143, the first connecting rod 141 and the second connecting rod 142.

[0080] In one embodiment of the present application, the escape ladder 1 further includes a third connecting rod 144, wherein the third connecting rod 144 has a ninth end 1441 and a tenth end 1442 arranged opposite to each other, wherein the ninth end 1441 is rotationally connected to the movable ladder 12, and the tenth end 1442 is rotationally connected to the eighth end 1422. Thus, when the movable ladder 12 is unfolded downward, the movable ladder 12 moving out of the sliding slot 111 will drive the third connecting rod 144 to move downward, and the movement of the third connecting rod 144 drives the first connecting rod 141 and the second connecting rod 142 to rotate clockwise, and the handrail 143 is unfolded. When the movable ladder 12 is stored in the sliding slot 111, the movable ladder 12 moves upward and drives the third connecting rod 144 to move upward, and the movement of the third connecting rod 144 drives the first connecting rod 141 and the second connecting rod 142 to rotate counterclockwise, and the handrail 143 is retracted. In this embodiment, a third connecting rod 144 is arranged between the handrail rod 143 and the movable ladder 12 to achieve mutual linkage between the handrail rod 143 and the movable ladder 12. The handrail rod 143 can be expanded and retracted as the movable ladder 12 is expanded and retracted, and no longer relies on human power. In this way, the structure of the handrail rod 143 is optimized and the convenience of using the escape ladder 1 is improved.
