Description

Technical Field

[0001] This invention relates to the field of rail vehicle tunnel technology, and in particular to a folding canopy coupling and uncoupling device, tunnel components, and rail vehicles. Background Technology

[0002] With the rapid development of the railway industry, high-speed railways, intelligent intercity railways, and unmanned subways have been widely applied. Automatic train operation and the automatic coupling and uncoupling of external components between carriages have also developed accordingly. To adapt to automatic operation and rapid automatic coupling and uncoupling, the connecting passage, as a major component of the train, needs to have corresponding automatic coupling and uncoupling functions developed, achieved through electric or pneumatic control. Currently, no application of automatic coupling and uncoupling of connecting passages has been found in existing technologies. Therefore, it is imperative to propose a new, highly efficient, manual-free, and time-saving automatic coupling system for windshields.

[0003] Existing folding carriages lack automatic coupling and discoupling functions, relying on purely mechanical installation with screws or manual locking. For rapid coupling and discoupling, manual separation and folding of the carriages are required. Removing screws or manually discoupling is time-consuming, especially in long train sets, which typically have over a dozen carriages requiring manual coupling and discoupling, consuming significant manpower, resources, and time. This is uneconomical and unacceptable in the context of automated trains. Therefore, enabling the separation and coupling of carriages in a very short time is a crucial issue.

[0004] A typical train has at least two carriages and at least one connecting passageway. When a train is reassembled or undergoes maintenance, adjacent carriages need to be separated. The separation point is where the connecting passageway is located. The first step is to separate the connecting passageway, followed by separating other connecting components. In normal operation, all carriages are connected together, and the connecting passageways between each carriage and adjacent carriages must also be connected. This means that the canopy of carriage one connects to the connecting frame of carriage two, and the ramp of carriage two rests on the step of carriage one. Common methods for connecting and disassembling connecting passageways are: connecting the connecting passageway is called coupling; separating the connecting passageway is called disassembly. The common method for connecting and disconnecting the passageway is to manually operate the locking device, manually push out the folding canopy of carriage one, and then lock it to the corresponding position of the connecting frame of carriage two. At the same time, the ramp of carriage two is lowered and placed on the step of carriage one. To disconnect, the locking device is manually opened, the folding canopy is separated from the connecting frame of carriage two, and pushed back into carriage one. At the same time, the ramp of carriage two is flipped up and stored in carriage two, completely separating the passageway between the two carriages.

[0005] In summary, the advantages of the above method are that both coupling and uncoupling can be manually confirmed, and the operation process and results are reliable; the disadvantage is that if there are many train crossings, a lot of manpower and time are required for operation, increasing time and labor costs.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0069] The following is combined Figures 1 to 5This invention describes a folding canopy coupling and uncoupling device, comprising: a folding canopy assembly 100 installed in a first carriage and a car body connecting frame 201 installed in a second carriage. It should be understood that the folding canopy assembly 100 and the car body connecting frame 201 are respectively installed on two adjacent carriages, thereby enabling the coupling or uncoupling of the folding canopy assembly 100 and the car body connecting frame 201.

[0070] Specifically, the folding canopy assembly 100 includes: a folding canopy body 110 and a telescopic mechanism 120.

[0071] One end of the folding canopy body 110 is fixed to the end of the first carriage, and the other end of the folding canopy body 110 can extend and retract in the direction of approaching or moving away from the second carriage. The other end of the folding canopy body 110 is equipped with a first locking element. The fixed end of the telescopic mechanism 120 is connected to one end of the folding canopy body 110, and the telescopic end of the telescopic mechanism 120 is connected to the other end of the folding canopy body 110. The folding canopy body 110 can extend and retract according to its structure. Its main body is composed of multi-ringed canopy fabric and a metal frame support. Each ring of the canopy fabric can be compressed and stretched. The entire folding canopy body 110 has compression and stretching functions and is also the basic component for connecting and untying the canopy in the passageway. The extension and retraction of the folding canopy body 110 is powered by the telescopic mechanism 120, whose horizontal extension and retraction movement drives the synchronous extension and retraction of the folding canopy body 110.

[0072] The vehicle body connecting frame 201 is provided with a second locking member that can cooperate with the first locking member; when the folding canopy body 110 is attached to the vehicle body connecting frame 201, the second locking member locks with the first locking member; when the folding canopy body 110 is unattached to the vehicle body connecting frame 201, the second locking member unlocks with the first locking member.

[0073] When the telescopic mechanism 120 moves the folding canopy body 110 toward the direction closer to the second carriage, and after it reaches its position, the locking engagement of the first locking member and the second locking member causes the folding canopy assembly 100 to be attached to the vehicle body connecting frame 201 and maintain its attached state (i.e., as shown). Figure 2 (As shown in the diagram). When the folding canopy assembly 100 needs to be disassembled, the first locking member and the second locking member are first unlocked, and then the telescopic mechanism 120 drives the folding canopy body 110 to move away from the second carriage. Finally, the folding canopy body 110 is retracted into the first carriage, realizing the disassembly of the folding canopy assembly 100 (i.e., as shown in the diagram). Figure 3 (The state shown).

[0074] It should be understood that the first and second locking components are mutually lockable and unlockable limiting components, and can adopt the structure of the locking rod 205 and locking hook 117 described in the following embodiments to ensure stable connection and quick unconnection. The above-mentioned connection and unconnection process can be completed by electronic or pneumatic control without manual operation.

[0075] This invention provides a folding canopy coupling and discoupling device, comprising: a folding canopy assembly 100 installed in a first carriage and a vehicle body connecting frame 201 installed in a second carriage; the folding canopy assembly 100 includes: a folding canopy body 110 and a telescopic mechanism 120; one end of the folding canopy body 110 is fixed to the end of the first carriage, and the other end of the folding canopy body 110 can telescopically move towards or away from the second carriage, and the other end of the folding canopy body 110 is provided with a first locking member; the fixed end of the telescopic mechanism 120 is connected to one end of the folding canopy body 110, and the telescopic end of the telescopic mechanism 120 is connected to the other end of the folding canopy body 110; the vehicle body connecting frame 201 is provided with a second locking member; when the folding canopy body 110 is coupled to the vehicle body connecting frame 201, the second locking member locks with the first locking member; when the folding canopy body 110 is discoupled from the vehicle body connecting frame 201, the second locking member unlocks with the first locking member. The present invention provides a folding canopy coupling and uncoupling device, which can drive the folding canopy body 110 to telescopically move through the telescopic mechanism 120, providing power for coupling and uncoupling. The first locking member and the second locking member can switch between locked and unlocked states, thereby ensuring stable coupling and rapid uncoupling of the folding canopy. The folding canopy coupling and uncoupling device of the present invention can replace manual coupling and uncoupling operations, providing convenience for the rapid coupling and uncoupling of the whole vehicle, reducing the waste of manpower and material resources and working time, and greatly improving work efficiency.

[0076] In one embodiment of the present invention, such as Figure 4 As shown, the folding canopy connecting and uncoiling device further includes a guide rail 116 and a slider 115. The guide rail 116 is fixed to the body of the first carriage and is arranged parallel to the extension direction of the carriage body. The slider 115 is fixed to the folding canopy body 110 and slidably mounted on the guide rail 116. In this embodiment, two guide rails 116 are arranged on the outer side of the first carriage body, and sliders 115 are respectively mounted on the two guide rails 116. The sliders 115 are fixedly connected to the side of the folding canopy body 110. By sliding the sliders 115 in the guide rails 116, the extension and retraction direction of the folding canopy body 110 is limited.

[0077] In one embodiment of the present invention, the folding canopy body 110 includes: a first folding canopy 111, a second folding canopy 112, and a folding canopy connecting frame 113; one end of the first folding canopy 111 is fixed to the first carriage, and the other end of the first folding canopy 111 is connected to one end of the second folding canopy 112 through the folding canopy connecting frame 113; the telescopic end of the telescopic mechanism 120 is connected to the other end of the second folding canopy 112. In this embodiment, the folding canopy body 110 includes a first folding canopy 111, a second folding canopy 112, and a folding canopy connecting frame 113. The second folding canopy 112 and the first folding canopy 111 are the front and rear folding canopies, respectively, and are connected by the folding canopy connecting frame 113. The folding canopy body 110 adopts the above-mentioned composite structure, which on the one hand can increase the telescopic distance of the folding canopy body 110, and on the other hand, the folding canopy connecting frame 113 fixes the front folding canopy (i.e., as shown in the image) during the telescopic process of the folding canopy body 110. Figure 4 and Figure 5 The second folding canopy 112 in the structure shown serves as the support point for the entire folding canopy, ensuring the structural stability of the folding canopy body 110. The telescopic mechanism 120 drives the front folding canopy (i.e., the second folding canopy 112) to move, thereby realizing the telescopic movement of the folding canopy body 110.

[0078] In one embodiment of the present invention, the slider 115 is fixed to the folding canopy connecting frame 113. Since the folding canopy connecting frame 113 in the above embodiment serves as the connecting structure between the front and rear folding canopies and as the support point for the entire folding canopy, fixing the slider 115 to the folding canopy connecting frame 113 can better limit the direction of the folding canopy's telescopic movement, ensuring that the folding canopy performs horizontal telescopic movement. In this embodiment, the guide rail 116 and the slider 115 provide support to the folding canopy connecting frame 113 on the one hand, and provide guidance for the movement of the folding canopy through the folding canopy connecting frame 113 on the other hand.

[0079] In one embodiment of the present invention, the folding canopy body 110 further includes a folding canopy docking frame 114, which is fixed to the other end of the second folding canopy 112. The folding canopy docking frame 114 is used to dock with the vehicle body connecting frame 201, and a first locking member is disposed on the folding canopy docking frame 114. In this embodiment, by installing the folding canopy docking frame 114 on the front folding canopy (i.e., the second folding canopy 112), it is used to fit with the vehicle body connecting frame 201 on the second carriage. When the two are fitted together, the folding canopy docking frame 114 and the vehicle body connecting frame 201 can be connected by locking the first locking member and the second locking member.

[0080] In one embodiment of the present invention, the telescopic mechanism 120 includes a drive motor 121 and a telescopic rod 122. The drive motor 121 is fixed to the first carriage; one end of the telescopic rod 122 is connected to the drive motor 121, and the other end is connected to the folding canopy docking frame 114. In this embodiment, the drive motor 121 provides power to drive the telescopic rod 122 to extend and retract, thereby driving the folding canopy body 110 to extend and retract. Specifically, the telescopic end of the telescopic rod 122 is connected to the folding canopy docking frame 114; its extension and retraction movement drives the folding canopy docking frame 114 to extend and retract, thereby driving the first folding canopy 111 and the second folding canopy 112 at its rear end to extend and retract synchronously.

[0081] In one embodiment of the present invention, the folding canopy assembly 100 further includes a foot pedal 130, one end of which is fixed to the folding canopy docking frame 114 and moves synchronously with the folding canopy docking frame 114, while the other end of the foot pedal 130 is movably disposed within the first carriage. In this embodiment, the foot pedal 130 is connected to the folding canopy docking frame 114 and moves with the movement of the folding canopy docking frame 114. When the folding canopy docking frame 114 extends to its final position, the foot pedal 130 also extends; when the folding canopy docking frame 114 retracts to its final position, the foot pedal 130 also retracts.

[0082] The present invention also provides a through-channel assembly. This through-channel assembly includes the folding and untying device described in the above embodiments of the present invention.

[0083] The present invention provides a through-channel assembly, which includes the folding and untying device of the above embodiments of the present invention, and therefore has the beneficial effects described above.

[0084] The through-passage assembly includes a slab tilting device, which is described below. Figures 6 to 11 The present invention describes a ferrule tilting device; the ferrule tilting device specifically includes: a vehicle body connecting frame 201, a ferrule body 202, a drive mechanism 204, and a second locking member. In this embodiment, the first locking member is a locking hook 117, and the second locking member is a locking rod 205.

[0085] Specifically, the ramp body 202 is rotatably connected to the vehicle body connecting frame 201; the drive mechanism 204 is located on the vehicle body connecting frame 201; one end of the locking rod 205 is connected to the drive mechanism 204, which is used to drive the locking rod 205 to move along the height direction of the vehicle body connecting frame 201, and the other end of the locking rod 205 can be connected to the ramp body 202 to drive the ramp body 202 to rotate.

[0086] In this embodiment, the ramp body 202 can be mounted on the vehicle body connecting frame 201 via a rotating shaft 203, and it can rotate via the rotating shaft 203. The drive mechanism 204 serves as the driving force for the rotation of the ramp body 202, driving the locking rod 205 to move along the height direction. The movement of the locking rod 205 drives the rotating shaft 203 to rotate, thereby driving the ramp body 202 to rotate. It should be understood that the linear movement of the locking rod 205 can be converted into the rotational movement of the rotating shaft 203 through a transmission mechanism, including a gear 211 and rack 209 or a lead screw transmission structure.

[0087] When the folding canopy docking frame 114 extends into position, the pedal 130 also extends. The drive mechanism 204 drives the locking rod 205 to move, the rotating shaft 203 rotates, and the ferrule body 202 rotates synchronously from a vertical state to a horizontal state and overlaps on the pedal 130. When the folding canopy needs to be retracted, the drive mechanism 204 is first controlled to drive the locking rod 205 to move in the opposite direction. The rotating shaft 203 rotates in the opposite direction, and the ferrule body 202 rotates synchronously in the opposite direction, from a horizontal state to a vertical state and is lifted off the pedal 130. Then the folding canopy docking frame 114 and the pedal 130 are retracted into the first carriage.

[0088] Furthermore, in order to ensure the stability of the coupling, locking rods 205 are arranged on both sides of the vehicle body connecting frame 201, and there are three locking rods 205 on each side. The three locking rods 205 are connected into an integral structure to ensure the uniformity of movement of the locking rods 205. Correspondingly, locking hooks 117 are also arranged on both sides of the folding canopy docking frame 114, and there are three locking hooks 117 on each side. The three locking hooks 117 are independently set.

[0089] This invention provides a ferrule flipping device, comprising: a vehicle body connecting frame 201, a ferrule body 202, a drive mechanism 204, and a locking rod 205. The ferrule body 202 is rotatably connected to the vehicle body connecting frame 201 via a rotating shaft 203. The drive mechanism 204 is mounted on the vehicle body connecting frame 201. One end of the locking rod 205 is connected to the drive mechanism 204, which drives the locking rod 205 to move along the height direction of the vehicle body connecting frame 201. The other end of the locking rod 205 can be connected to the rotating shaft 203 to drive the ferrule body 202 to rotate around the rotating shaft 203. In this ferrule flipping device, the drive mechanism 204 acts as the driving force, driving the rotating shaft 203 to rotate via the locking rod 205, thereby enabling the ferrule body 202 to flip on the vehicle body connecting frame 201. When the vehicle body connecting frame 201 is attached or detached, this device replaces manual operation, achieving automatic flipping of the ferrule, reducing manpower waste and working time, and greatly improving work efficiency.

[0090] In one embodiment of the present invention, the ferrule flipping device further includes a transmission mechanism located at the other end of the locking rod 205. The transmission mechanism is connected to the ferrule body 202 via a rotating shaft 203 to drive the ferrule body 202 to flip around the rotating shaft 203. Preferably, the transmission mechanism includes a rack 209 and a gear 211; the rack 209 is connected to the locking rod 205; the gear 211 is connected to the rotating shaft 203 and can drive the rotating shaft 203 to rotate, and the gear 211 can mesh with the rack 209. In this embodiment, the linear motion of the locking rod 205 is converted into the rotational motion of the rotating shaft 203 through the transmission mechanism composed of the gear 211 and the rack 209. It should be understood that the movement of the locking rod 205 can only be converted into the movement of the rotating shaft 203 when the gear 211 meshes with the rack 209. In other words, if the locking rod 205 moves to a position where the rack 209 is not meshed with the rack 209, the movement of the locking rod 205 cannot drive the rotating shaft 203 to rotate. By properly arranging the meshing relationship between the gear 211 and the rack 209, the problem of the plate body 202 possibly overturning can be avoided.

[0091] In one embodiment of the present invention, a locking hole 2051 is formed on the locking rod 205. When the locking rod 205 drives the plate body 202 to rotate to the connected state, the locking hook 117 is inserted into the locking hole 2051 and locked; when the locking rod 205 drives the plate body 202 to rotate to the unconnected state, the locking hook 117 disengages from the locking hole 2051 and unlocks. Specifically, the locking hole 2051 is an elongated locking hole 2051, and a baffle is provided above the locking hole 2051. When the locking hook 117 is inserted into the locking hole 2051, the baffle can be engaged with the locking hook 117 by the movement of the locking rod 205, thereby achieving the locking of the locking hook 117 and the locking rod 205; when the locking hook 117 and the locking rod 205 need to be unlocked, the locking rod 205 only needs to be moved in one direction, and the locking hook 117 can be moved horizontally out of the locking hole 2051 under the action of the folding frame 114. Figure 2 , Figure 5 , Figure 6 and Figure 10 In the structure shown, when the folding canopy docking frame 114 moves to fit against the vehicle body connecting frame 201, the locking hook 117 is inserted into the corresponding hole. After the locking rod 205 moves downward, the end of the locking hook 117 is blocked by the baffle above the locking hole 2051, thereby locking the locking hook 117 and the locking rod 205.

[0092] In one embodiment of the present invention, such as Figure 7In the structure shown, the vehicle body connecting frame 201 is provided with a guide hole 206. The fixed end of the drive mechanism 204 is fixed to one side of the vehicle body connecting frame 201, and the movable end of the drive mechanism 204 passes through the guide hole 206 and moves within the guide hole 206. The movable end of the drive mechanism 204 is connected to a locking rod 205 located on the other side of the vehicle body connecting frame 201. In this embodiment, the drive mechanism 204 and the locking rod 205 are located on both sides of the vehicle body connecting frame 201, respectively. The movable end of the drive mechanism 204 can be connected to the locking rod 205 through a connecting rod passing through the guide hole 206. The guide hole 206 is used to limit the movement direction of the locking rod 205, ensuring that the locking rod 205 moves vertically.

[0093] In one embodiment of the present invention, such as Figure 11 In the structure shown, gear 211 is a quarter-circular gear. When the locking rod 205 drives the plate body 202 to rotate to the engaged state, the quarter-circular gear rotates to one end and engages with the rack 209; when the locking rod 205 drives the plate body 202 to rotate to the disengaged state, the quarter-circular gear rotates to the other end and engages with the rack 209. In this embodiment, since the plate body 202 only rotates 90° during the entire flipping process, which is the angle of a quarter circle, the pitch circle of gear 211 is also designed as a quarter circle. To ensure that the rack 209 engages with one end of the quarter-circular gear in the horizontal / vertical state, after the plate body 202 rotates to the vertical / horizontal state, the rack 209 moves to the other end of the quarter-circular gear. Afterward, the rack 209 no longer engages with gear 211, the rack 209 continues to move, and gear 211 does not rotate, keeping the plate body 202 stationary. Therefore, through the gear 211 design described above, it can be ensured that the ferrule body 202 rotates only within a 90° range between horizontal and vertical, thereby avoiding the problem of excessive rotation of the ferrule body 202.

[0094] In one embodiment of the present invention, the gear 211 has a through hole, and the rotating shaft 203 is inserted into the through hole. Specifically, the through hole is arranged at the rotation center of the gear 211, the rotating shaft 203 passes through the through hole, and rotates synchronously with the gear 211.

[0095] In one embodiment of the present invention, such as Figure 8 and Figure 9 In the structure shown, the ramp flipping device further includes a connector 208, which is connected between the locking rod 205 and the rack 209. Additionally, a guide groove is provided on the vehicle body connecting frame 201, and the connector 208 is embedded in the guide groove. The guide groove limits the position of the connector 208, preventing it from bending or deforming.

[0096] In one embodiment of the present invention, such as Figure 8 and Figure 9 In the structure shown, the ramp flipping device further includes a limiting block 210, which is fixed to the connector 208 and fits against one side of the vehicle body connecting frame 201 to limit the movement of the connector 208. Specifically, the limiting block 210 can be a nylon block, which is installed on the connector 208. The nylon block fits against the vehicle body connecting frame 201 to limit the movement of the connector 208 and also prevents the connector 208 from bending and deforming.

[0097] In one embodiment of the present invention, the plate flipping device further includes: a mounting base 207, which is fixed on the vehicle body connecting frame 201, and the gear 211 is rotatably mounted on the mounting base 207; the mounting base 207 is used to mount the gear 211, that is, the gear 211 seat.

[0098] The present invention also provides a rail vehicle. This rail vehicle can be a subway train, urban rail train, or high-speed rail train, or it can be an unmanned train, comprising: the folding canopy coupling and uncoupling device of the above embodiments of the present invention, or the through-passage assembly of the above embodiments of the present invention.
