Description

Technical Field

[0001] The present invention belongs to the technical field of rail transportation and relates to a remote isolation device, in particular to a remote isolation device for a vehicle door and a vehicle door system. Background Art

[0002] Due to their high frequency of use, subway vehicle door systems are prone to malfunctions during operation. For subway vehicles with extremely high safety requirements, the vehicle door systems are absolutely prohibited from opening during operation. If a vehicle door system malfunctions, it must be mechanically locked and electrically isolated, removing it from service, before the subway vehicle can continue operating.

[0003] Isolation devices are essential components for subway car passenger compartment side doors. Currently, most domestic subway car passenger compartment side door systems utilize local isolation devices, requiring staff to manually close the faulty door and then operate the local isolation device to isolate the vehicle. However, locating the faulty door and performing the isolation operation requires significant effort and troubleshooting time, inevitably causing train delays. Furthermore, existing isolation devices are complex, require numerous components, are prone to failure, and have low reliability.

[0004] Moreover, with the popularization of unmanned trains, when a vehicle door malfunctions, there will be no train attendant to perform manual operation, so there are corresponding safety hazards. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a remote isolation device that can remotely control the mechanical locking of vehicle doors and has a simple structure and high reliability.

[0006] The object of the present invention can be achieved by the following technical solutions: A remote isolation device for a vehicle door, comprising:

[0009] An electromagnet assembly is mounted on the base plate and is located at the same end of the screw as the fixed block, wherein the electromagnet assembly includes a mounting plate, and an electromagnet is connected to the mounting plate, the extension direction of the iron core on the electromagnet is perpendicular to the axial direction of the screw, and the iron core and the handle are located on both sides of the transmission member;

[0010] Among them, when the vehicle door is in a normal state, the iron core and the transmission member provided with one end of the handle form an upper and lower abutment fit, and the convex part on the plug block is separated from the concave part on the fixed block; when the vehicle door fails, the electromagnet is energized, the iron core retracts, and the abutment of the iron core on the transmission member is released, prompting the transmission member to rotate counterclockwise around the isolation bracket, so that the convex part on the plug block is inserted into the concave part of the fixed block, thereby limiting the rotation of the screw rod and realizing mechanical isolation of the vehicle door.

[0018] The present invention also provides a vehicle door system, comprising the remote isolation device for the vehicle door.

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] like Figures 1 to 12 As shown, the present invention provides a remote isolation device for a vehicle door, comprising:

[0039] The base plate 100 has a transmission assembly 200 mounted thereon. The transmission assembly 200 includes a screw rod 210 and a fixed block 220 connected to the end of the screw rod 210 and rotating synchronously with the screw rod 210. The axis direction of the screw rod 210 is consistent with the length direction of the base plate 100, and the fixed block 220 is provided with a recess 221.

[0040] The isolation assembly 300 is mounted on the base plate 100 and is located at the same end of the screw rod 210 as the fixed block 220. The isolation assembly 300 includes an isolation bracket 310, and a transmission member 320 is rotatably connected to the isolation bracket 310. The length direction of the transmission member 320 is consistent with the axial direction of the screw rod 210. An insert block 330 is provided at one end of the transmission member 320, and a convex portion 331 is provided on the insert block 330 to cooperate with the concave portion 221. A handle 321 is provided at the other end of the transmission member 320. The length direction of the handle 321 is perpendicular to the axial direction of the screw rod 210.

[0041] The electromagnet assembly 400 is mounted on the base plate 100 and is located at the same end of the screw rod 210 as the fixing block 220. The electromagnet assembly 400 includes a mounting plate 410, to which an electromagnet 420 is connected. The extension direction of the iron core 421 of the electromagnet 420 is perpendicular to the axis of the screw rod 210. The iron core 421 and the handle 321 are located on either side of the transmission member 320.

[0042] Among them, when the vehicle door is in a normal state, the iron core 421 forms an upper and lower abutment fit with the transmission member 320 provided with one end of the handle 321, and the protrusion 331 on the plug block 330 is separated from the recess 221 on the fixed block 220; when the vehicle door fails, the electromagnet 420 is energized, the iron core 421 retracts, and the abutment of the iron core 421 on the transmission member 320 is released, prompting the transmission member 320 to rotate counterclockwise around the isolation bracket 310, so that the protrusion 331 on the plug block 330 is inserted into the recess 221 of the fixed block 220, thereby limiting the rotation of the screw rod 210 and realizing mechanical isolation of the vehicle door.

[0043] It is worth mentioning that when the vehicle door fails during driving, the vehicle door needs to be closed again, thereby ensuring that the recess 221 on the fixed block 220 and the protrusion 331 on the plug block 330 are on the same horizontal line. At this time, the electromagnet 420 is energized, releasing the upper and lower abutment between the iron core 421 and the transmission member 320, prompting the transmission member 320 to rotate counterclockwise around the isolation bracket 310, so that the protrusion 331 on the plug block 330 is inserted into the recess 221 of the fixed block 220, limiting the rotation of the screw rod 210, and realizing the mechanical locking of the vehicle door.

[0044] When the fault is eliminated, the electromagnet 420 loses power, the iron core 421 extends, and then the transmission member 320 is rotated clockwise by the handle 321 to release the plug-in fit between the protrusion 331 on the plug block 330 and the recess 221 on the fixed block 220, and the abutment fit between the iron core 421 and the transmission member 320 is completed again, thereby unlocking the screw rod 210.

[0045] The present invention provides a remote isolation device for a vehicle door, which can remotely control the mechanical locking of the vehicle door and has a simple structure and high reliability.

[0046] Preferably, the isolation bracket 310 is arranged in an L-shape, and a first connecting column 311 is extended along the axial direction of the screw rod 210 on one side of the isolation bracket 310 toward the end of the screw rod 210, and the plug block 330 is embedded in the first connecting column 311, and the plug block 330 is locked in the first connecting column 311 by a fastener, wherein a second connecting column 312 is extended toward the telescopic direction of the iron core 421 on the isolation bracket 310, and a spring 340 is nested on the second connecting column 312, and the transmission member 320 is nested on the second connecting column 312, and the transmission member 320 is limited to move along the axial direction of the second connecting column 312 by a retaining spring.

[0047] It is worth mentioning that the spring 340 provides the iron core 421 with a torque to drive the transmission member 320 to rotate counterclockwise when the iron core 421 is released from the abutment with the transmission member 320, ensuring that the protrusion 331 on the insert block 330 can be reliably inserted into the recess 221 of the fixed block 220, thereby limiting the circumferential freedom of the screw rod 210.

When the iron core 421 releases the abutment between the rotating block 325, the trigger plate 360 ​​rotates synchronously counterclockwise with the rotating block 325, so that the trigger plate 360 ​​touches the switch key 351, prompting the micro switch 350 to send an isolation signal.

[0050] It is worth mentioning that the mechanical isolation of the vehicle door is achieved by the plug-in cooperation between the protrusion 331 of the plug block 330 and the recessed portion 221 of the fixed block 220, and the sending of the electrical isolation signal is achieved by pressing the switch key 351 on the micro switch 350 through the trigger plate 360, thereby achieving the synchronous isolation of mechanical isolation and electrical isolation of the vehicle door when a fault occurs, thereby further improving the reliability of remote isolation of the vehicle door.

[0051] Preferably, a boss 326 is formed on the handle 321 extending along the axial direction of the handle 321, and the diameter of the boss 326 is smaller than the diameter of the handle 321, wherein the end of the boss 326 connected to the handle 321 is a smooth section, and the end of the boss 326 away from the handle 321 is a threaded section, and the trigger plate 360 ​​is nested in the smooth section, and the handle cover 327 is screwed to the threaded section, clamping the trigger plate 360 ​​between the handle 321 and the handle cover 327, so that the trigger plate 360 ​​can rotate synchronously with the rotating block 325.

[0052] It is worth mentioning that the trigger plate 360 ​​is in the shape of a whistle, and the columnar side of the trigger plate 360 ​​forms a nested fit with the protrusion 326 , and the plate-shaped side of the trigger plate 360 ​​serves as the trigger end of the trigger switch key 351 .

[0053] Preferably, the boss 326 and the trigger plate 360 ​​form a polygonal nesting fit, thereby limiting the circumferential freedom of the trigger plate 360 ​​on the boss 326 , further ensuring that the trigger plate 360 ​​can rotate synchronously with the rotating block 325 .

[0054] Preferably, the fixing block 220 is arranged in a columnar shape, and a through hole 222 is provided along the axial direction of the fixing block 220, and a strip groove 223 extending along the axial direction of the fixing block 220 is provided on the hole wall of the through hole 222, and a first connecting hole 224 is provided on each side of the strip groove 223, wherein the two first connecting holes 224 are coaxially arranged, and the recess 221 is provided on the hole wall of the through hole 222. When the fixing block 220 is nested on the screw rod 210, the fastener is penetrated into the two first connecting holes 224 to realize the embracing fit of the fixing block 220 with the screw rod 210, so that the fixing block 220 can rotate synchronously with the screw rod 210.

[0055] Preferably, the plug block 330 is arranged in a columnar shape, and a positioning groove 332 is provided along the axial direction of the plug block 330 and on the side wall of the plug block 330.
