[0049] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Please refer to Figures 1 to 8 , Figure 1 A front view of a partition door system in a closed state in a specific embodiment provided by the present invention; Figure 2 for Figure 1 Middle AA section view; Figure 3 for Figure 1 A magnified schematic diagram of the middle I part; Figure 4a , Figure 4b They are respectively a front view and a rear view of a locking component in a specific embodiment; Figure 5 for Figure 1 Middle BB section view; Figure 6 for Figure 1 An enlarged schematic diagram of the middle II part; Figure 7 for Figure 1 Middle CC section view; Figure 8 for Figure 1 Schematic diagram of the enlarged view of the III region.

[0051] The partition door system provided in this embodiment is used for a rail vehicle, which includes multiple carriages. Two adjacent carriages are separated by a partition door system. The passage between the two adjacent carriages can be connected or closed by opening and closing the partition door system, so that the two adjacent carriages can be closed as relatively independent spaces as needed or connected for passengers to pass through.

[0052] It can be understood that the partition door system is arranged at the junction of two adjacent carriages.

[0053] In this embodiment, the partition door system includes a supporting component 200 fixed on the top of the vehicle body, a driving component installed on the supporting component 200, a left door leaf 110a and a right door leaf 110b, wherein the driving component can drive the left door leaf 110a and the right door leaf 110b to move toward each other to close the door system or move away from each other to open the door system.

[0054] Obviously, the moving direction of the left door leaf 110a and the right door leaf 110b is the lateral direction of the rail vehicle, that is, the width direction of the rail vehicle.

[0055] like Figure 5As shown, in this embodiment, the bearing component 200 is provided with a groove-shaped portion 210, the opening of the groove-shaped portion 210 is toward one side of the door leaf, and the groove-shaped portion 210 specifically includes a bottom wall plate 211 and two parallel side wall plates extending from the bottom wall plate 211 to one side of the door leaf. It can be understood that the two side wall plates are arranged in the height direction of the rail vehicle. For the convenience of description, they are referred to as the upper side wall plate 213 and the lower side wall plate 212. In this way, the upper side wall plate 213, the bottom wall plate 211 and the lower side wall plate 212 enclose the groove-shaped portion 210 with the opening toward one side of the door leaf.

[0056] Specifically, the bearing component 200 is fixedly mounted with the vehicle body 600 through the bottom wall plate 211, and fasteners such as bolts can be selected to facilitate disassembly, assembly and maintenance.

[0057] To facilitate the installation of other components, the supporting component 200 also includes an extended wall portion 220 extending upward from the bottom wall plate 211. The extended wall portion 220 is also fixed to the vehicle body 600 by fasteners such as bolts to ensure the reliability of the connection between the supporting component 200 and the vehicle body 600, as well as the connection reliability of other components installed on the supporting component 200.

[0058] like Figure 5 As shown, after the above arrangement, it can be understood that the cross section of the bearing component 200 is generally in an inverted F shape.

[0059] The inner wall of the lower side wall plate 212 of the groove-shaped portion 210 of the bearing member 200 has a guide rail protrusion 2121 extending in the vehicle transverse direction. It can be understood that the length direction of the bearing member 200 extends in the vehicle transverse direction.

[0060] The left door leaf 110 a and the right door leaf 110 b are both equipped with a load-bearing wheel 130 , an anti-jump wheel 140 and a limit wheel 150 that match the load-bearing component 200 .

[0061] Specifically, refer to Figure 5 and Figure 6 The load-bearing wheel 130 is slidably matched with the above-mentioned guide rail protrusion 2121, the anti-jump wheel 140 is located in the groove-shaped cavity of the groove-shaped portion 210 and contacts the upper side wall plate 213 of the groove-shaped portion 210, and the limiting wheel 150 is located below the groove-shaped portion 210 and contacts the outer wall surface of the lower side wall plate 212 thereof.

[0062] In this way, during the opening or closing process of the door leaf, the sliding cooperation between the load-bearing wheel 130 and the guide rail protrusion 2121 can ensure the guiding of the movement. The setting of the anti-jump wheel 140 can prevent the door leaf from jumping during the movement, so as to ensure the stability and reliability of opening and closing. At the same time, combined with the limiting cooperation of the limiting wheel 150, it can ensure that the door leaf is in a vertical position to prevent a gap from appearing at the bottom of the door leaf.

[0063] As described above, the matching structure between the door leaf and the bearing component 200 can ensure the stability and reliability of the opening and closing of the door leaf, and prevent the door leaf from jumping and the formation of a gap between the door leaf and the vehicle body.

[0064] It should be pointed out that at least one set of load-bearing wheels 130, anti-jump wheels 140 and limiting wheels 150 that cooperate with the load-bearing component 200 is provided on the left door leaf 110a and the right door leaf 110b. Of course, in practice, two or more sets can be provided on each door leaf as needed.

[0065] In this embodiment, the driving component includes a driving motor 320, synchronous wheels 330 installed at both ends of the supporting component 200, and a synchronous belt 340 tensioned on the two synchronous wheels 330, wherein the left door leaf 110a is fixedly connected to the synchronous belt 340 through the left door frame 120a, and the right door leaf 110b is fixedly connected to the synchronous belt 340 through the right door frame 120b; the driving motor 320 is used to drive the synchronous wheel 330 to rotate to drive the synchronous belt 340 to rotate.

[0066] During operation, the driving motor 320 drives the synchronous wheel 330 to rotate, thereby driving the synchronous belt 340 to rotate, and further driving the left door leaf 110a and the right door leaf 110b to move to open or close the door system.

[0067] Obviously, in order to enable the left door leaf 110a and the right door leaf 110 to move simultaneously in the door opening direction or the door closing direction, one is connected to the upper part of the synchronous belt 340, and the other is connected to the lower part of the synchronous belt 340.

[0068] like Figure 1 As shown, specifically, the driving motor 320 and the synchronous wheel 330 are both installed on the upper side wall plate 213 of the bearing component 200 .

[0069] In a specific solution, the partition door system further includes a door controller 310 that is communicatively connected to the vehicle controller, and the door controller 310 is communicatively connected to the drive motor 320. A control signal for opening or closing the door can be sent to the door controller 310 through the vehicle controller to control the forward or reverse rotation of the drive motor 320, thereby realizing the opening or closing action of the door system. It can be understood that when the drive motor 320 rotates forward, it drives the synchronous belt 340 to rotate in one direction, and when it rotates reversely, it drives the synchronous belt 340 to rotate in the opposite direction. When specifically set, the forward rotation of the drive motor 320 can correspond to the door opening direction or the door closing direction as needed.

[0070] Usually, the vehicle controller is installed in the cab, and the cab is equipped with a control panel and operation buttons to facilitate the transmission of instructions to the vehicle controller or the viewing of the relevant status of various control components of the vehicle. The setting of the door controller 310 allows the driver to understand the status of the partition door system in the cab, so as to facilitate the corresponding operation.

[0071] In this embodiment, the partition door system further includes a locking component 400 for locking the left door leaf 110a and the right door leaf 110b in a closed position to ensure reliable locking of the door system.

[0072] refer to Figure 1 , Figure 3 and Figure 4a , 4b In this solution, the locking component 400 is specifically located at the junction of the left door leaf 110a and the right door leaf 110b when the door is closed, and the locking component 400 is installed on the bearing component 200.

[0073] In a specific solution, the locking component 400 includes a fixing seat 410 , a push-pull electromagnet 420 installed on the fixing seat 410 , and a locking hook 440 .

[0074] Among them, the movable end of the push-pull electromagnet 420 is connected to a cam 430, and the cam 430 is fixedly connected to the lock hook member 440; the lock hook member 440 has two hook portions 441, and the left door leaf 110a and the right door leaf 110b are both provided with lock groove portions, and the two lock groove portions are respectively matched with the two hook portions 441. Specifically, when the hook portion 441 is embedded in the lock groove portion, the corresponding door leaf can be locked to restrict its movement.

[0075] The push-pull electromagnet 420 can drive the cam 430 to rotate so that the two hook portions 441 of the lock hook member 440 are respectively locked with the two lock groove portions, or the two hook portions 441 are respectively separated from the two lock groove portions.

[0076] The specific configuration is as follows: when the push-pull electromagnet 420 is energized, its movable end retracts, driving the cam 430 to rotate, thereby driving the lock hook 440 fixedly connected to the cam 430 to rotate until its two hook portions 441 are respectively engaged in the lock groove portions of the left door leaf 110a and the right door leaf 110b, so as to lock the positions of the left door leaf 110a and the right door leaf 110b; when the push-pull electromagnet 420 is de-energized, its movable end extends out under the action of the reset spring, driving the cam 430 to rotate in the opposite direction, thereby driving the lock hook 440 fixedly connected to the cam 430 to rotate in the opposite direction until its two hook portions 441 are respectively disengaged from the lock groove portions of the left door leaf 110a and the right door leaf 110b, so that the left door leaf 110a and the right door leaf 110b can be moved.

[0077] Furthermore, the locking component 400 also includes a detection switch 450 that is communicatively connected to the vehicle controller. The detection switch 450 can feed back a signal indicating the state of the locking component 400 to the vehicle controller so that the driver can know the state of the partition door system and perform corresponding operations.

[0078] The specific configuration is as follows: when the push-pull electromagnet 420 is energized, the cam 430 drives the hook portion 441 of the lock hook member 440 to be embedded in the lock groove portion, and the cam 430 triggers the contact 451 of the detection switch 450, and the detection switch 450 feeds back a signal that the locking component 400 is in a locked state to the vehicle controller; when the push-pull electromagnet 420 is de-energized, the cam 430 drives the hook portion 441 of the lock hook member 440 to disengage from the lock groove portion, and the contact of the detection switch 450 is reset, and the detection switch 450 feeds back a signal that the locking component 400 is in an unlocked state to the vehicle controller.

[0079] like Figure 4b As shown, the detection switch 450 is also fixed to the fixing base 410 , and its contact is located on the rotation track of the cam 430 , and is configured to press the contact 451 of the detection switch 450 to trigger the detection switch 450 when the cam 430 rotates in the locking direction.

[0080] In specific applications, when the vehicle is running, the partition door system is in a powered-on state, and the door controller 310 can control the drive motor 320 to rotate forward or reverse to drive the door leaf to open or close. When the door leaf is in a closed position, the locking component 400 is also in a locked state to reliably lock the door system and isolate passengers from different compartments. The door controller 310 can also control the locking component 400 to be in an unlocked state, so that the door leaf is released and can move in the direction of opening the door driven by the drive component.

[0081] In this embodiment, in order to facilitate the opening of the door leaf after the door system is powered off, a reset component is also provided to enable the door leaf to automatically move in the door opening direction after the door system is powered off, so as to realize automatic door opening.

[0082] In actual application, when the vehicle is operating normally, a door closing signal can be sent to the door controller 310 through the vehicle controller in the cab. After receiving the door closing signal, the door controller 310 controls the drive motor 320 to rotate in the direction corresponding to the door closing, so as to drive the left door leaf 110a and the right door leaf 110b to move toward each other to close the door system. After the left door leaf 110a and the right door leaf 110b are closed, the push-pull electromagnet 420 of the locking component 400 can be controlled to be energized to lock the left door leaf 110a and the right door leaf 110b. The setting of the locking component 400 can ensure the reliability of the door system closing in the energized state, provide relatively independent space for passengers in the car, and ensure the riding comfort of passengers. It can be understood that the energization operation of the locking component 400 is performed after the left door leaf 110a and the right door leaf 110b move toward each other and close. Specifically, the energization operation of the locking component 400 can be ensured by pre-storing the set time of the door closing action.

[0083] When the door needs to be opened, a door opening signal can be sent to the door controller 310 through the vehicle controller in the cab. After receiving the door opening signal, the door controller 310 controls the locking component 400 to cut off the power to release the lock of the left door leaf 110a and the right door leaf 110b, and controls the drive motor 320 to rotate in the direction corresponding to the door opening, so as to drive the left door leaf 110a and the right door leaf 110b to move oppositely to open the door system.

[0084] When the vehicle encounters an emergency or unexpected power outage, the locking component 400 is in an unlocked state, and the left door leaf 110a and the right door leaf 110b can move away from each other under the action of the reset assembly to achieve automatic door opening, forming an evacuation passage to ensure the safety of passengers.

[0085] Specifically, the reset assembly includes two reset components installed on the bearing component 200, which act on the left door leaf 110a and the right door leaf 110b respectively.

[0086] refer to Figure 1 and Figure 8 In this scheme, the reset component includes a box body 510 and a pull rope 520, wherein the box body 510 is arranged near the end of the bearing component 200 and is fixed to the bearing component 200, one end of the pull rope 520 is connected to the elastic member in the box body 510, and the other end extends out of the box body 510 and is fixed to the door carrying frame on the corresponding side, and has a pulling force to pull the door carrying frame on the corresponding side in the direction of opening the door.

[0087] Specifically, the pull rope 520 of the reset component close to the left side is fixedly connected to the left carrying door frame 120a, and the pull rope 520 provides a pulling force to move the left carrying door frame 120a toward the left side. When the left carrying door frame 120a is not affected by other external forces, under the action of this pulling force, the left door leaf 110a can be driven to move to the left side to open the door and keep it in the open position; the pull rope 520 of the reset component close to the right side is fixedly connected to the right carrying door frame 120b, and the pull rope 520 provides a pulling force to move the right carrying door frame 120b toward the right side. When the right carrying door frame 120b is not affected by other external forces, under the action of this pulling force, the right door leaf 110b can be driven to move to the right side to open the door and keep it in the open position.

[0088] When the partition door system is powered on, the driving motor 320 drives the synchronous belt 340 to rotate in the door closing direction, driving the left door frame 120a and the right door frame 120b to move in the door closing direction to overcome the pulling force of the reset component. After the partition door system is powered off, there is no external force. Under the pulling force of the reset component, the left door leaf 110a and the right door leaf 110b are driven to move in the door opening direction and remain in the door opening position.

[0089] refer to Figure 1 and Figure 7In a specific solution, a lower guide rail 800 is provided on the floor 900 of the rail vehicle corresponding to the left door leaf 110a and the right door leaf 110b, and the left door leaf 110a and the right door leaf 110b are slidably connected to the lower guide rail 800. In this way, when the door system is opened and closed, there are guide structures on the upper and lower parts of the left door leaf 110a and the right door leaf 110b, which can better ensure the stability and reliability of movement.

[0090] Specifically, the lower rail 800 may be fixed to the floor 900 by fasteners such as screws.

[0091] Wherein, thresholds 800 are fixed on both sides of the lower guide rail 800. Figure 7 As shown, the threshold 800 includes a plane portion at a preset height from the floor 900 and an inclined portion connecting the plane portion and the floor 900. This arrangement can facilitate the smooth passage of passengers or carts.

[0092] refer to Figure 2 and Figure 5 In a specific solution, a door frame strip 630 is fixedly installed at a portion of the vehicle body 600 that matches the door leaf. The door frame strip 630 is provided with an installation groove facing the left door leaf 110a or the right door leaf 110b. An expansion rubber strip 640 is embedded in the installation groove and is configured as follows: under normal conditions, the expansion rubber strip 640 does not contact the left door leaf 110a or the right door leaf 110b. When in a heat-expanded state, the expansion rubber strip 640 is tightly attached to the left door leaf 110a or the right door leaf 110b to prevent smoke and fire from passing through.

[0093] Specifically, the door frame molding 630 can be fixedly connected to the vehicle body 600 by fasteners such as screws, and the expansion strip 640 can be bonded into the installation groove of the door frame molding 630 .

[0094] It can be understood that expansion strips 640 are provided between the periphery of the door leaf and the vehicle body 600. In this way, when a fire occurs, the expansion strips 640 expand due to heat and adhere closely to the door leaf, thereby sealing the connection between the door leaf and the vehicle body 600, blocking the passage of smoke and fire, and providing reliable safety protection for passengers to evacuate the vehicle.

[0095] In specific plans, such as Figure 1 As shown, an electric key switch 610 is provided on the vehicle body 600 near the left door leaf 110a, and the electric key switch 610 is communicated with the door controller 310 to control the opening and closing of the left door leaf 110a and the right door leaf 110b; in this way, it is convenient for the crew to open and close the corresponding door system by key.

[0096] In actual configuration, the electric key switch 610 may also be disposed on a side of the vehicle body 600 close to the right door leaf 110b.

[0097] In specific plans, such as Figure 1As shown, an emergency operation switch 620 is also provided on the vehicle body 600 near the left door leaf 110a. The emergency operation switch 620 can be used to control the power on and off of the partition door system, that is, the opening and closing status of the door, so that when an emergency occurs, the emergency operation switch 620 can be used to cut off the power to the door system and open the door system to form an evacuation passage.

[0098] In actual configuration, the emergency operation switch 620 may also be disposed on a side of the vehicle body 600 close to the right door leaf 110b.

[0099] In addition to the above partition door system, the present invention also provides a control method for the partition door system, the control method comprising:

[0100] When the partition door system is powered on:

[0101] Send a door closing signal to the door controller 310, the door controller 310 controls the driving motor 320 of the driving component to rotate in the door closing direction to drive the left door leaf 110a and the right door leaf 110b to move towards each other to achieve door closing, and after the door is closed, the relative position of the left door leaf 110a and the right door leaf 110b is locked;

[0102] The door opening signal is sent to the door controller 310 to unlock the left door leaf 110a and the right door leaf 110b. The door controller 310 controls the driving motor 320 of the driving component to rotate in the door opening direction to drive the left door leaf 110a and the right door leaf 110b to move in opposite directions to open the door.

[0103] In a specific solution, a door opening or closing signal can be sent to the door controller 310 via the electric key switch 610 or a control button on the cab control console.

[0104] The control method also includes: during the door opening process, if the door leaf stops due to an obstacle, determining whether the cumulative number of times the door leaf stops due to an obstacle during this door opening process reaches a set number, if so, keeping the door leaf stopped at the obstacle position, the door controller 310 sends a fault alarm signal, and after the fault is resolved, controlling the door leaf to open, if not, making the door leaf stop at the obstacle position for a set time before closing and then moving in the direction of opening the door.

[0105] This arrangement can prevent the partition door system from encountering obstacles during the door opening process and causing adverse consequences such as squeezing.

[0106] The above-mentioned setting times and setting time can be set as required.

[0107] The control method also includes: during the door closing process, if the door leaf stops due to an obstacle, determining whether the cumulative number of times the door leaf stops due to an obstacle during the door closing process reaches a preset number, if so, the door leaf stops at the open position, and the door controller 310 sends a fault alarm signal, and after the fault is resolved, controls the door leaf to close, if not, makes the door leaf return to the open position after stopping at the fault position for a preset time, and then moves in the closing direction.

[0108] This arrangement can prevent the partition door system from encountering obstacles during the closing process and causing adverse consequences such as squeezing.

[0109] When the partition door system is powered on and the door controller 310 controls the door leaf to be closed, in an emergency, the partition door system can be powered off through the emergency operation switch 620, so that the door leaf can be opened under the action of the reset component.

[0110] In the specific scheme, after the left door leaf 110a and the right door leaf 110b are in the closed state and the relative position of the two is locked, a door closing signal is also fed back to the cab control console; after the partition door system receives a power-off signal and unlocks the left door leaf 110a and the right door leaf 110b, a door opening signal is also fed back to the cab control console.

[0111] The corresponding control actions of each component have been described in detail above and will not be repeated here.
