[0002] When existing rail transit trains stop at platforms, there is a large gap between the outside of the door and the platform. When passengers get on and off the train, they need to step over the gap, and there is a possibility of stepping into the gap and falling. Therefore, platform compensators for reducing the gap are installed on the platform. However, the existing platform compensators have the following defects: (1) The main frame of the platform compensator adopts a welded and assembled structure, and the support surface adopts an adhesive curing structure. The structure is complex, the cost is high, the process and feasibility are poor, and it is not conducive to mass production; (2) The horizontal locking device of the existing platform compensator adopts a gear-rack transmission structure, which is complex and costly, and the gear-rack cannot achieve position locking, which will cause the horizontal lock to reverse during vehicle operation and vibration, resulting in door system failures; (3) The top lock core of the existing platform compensator adopts a rubber plug, the passenger interface is poor, and it is easy to be lost and damaged; (4) The existing platform compensator is not provided with an emergency fault handling mechanism; (5) The gas spring used in the existing platform compensator has no damping, and the impact at the end of flipping is large, posing a risk of pinching people.

The striker 102 is connected to the locking pin 101 by screws, and the locking pin 101 drives the striker 102 to move telescopically within the housing 103. The shifting block 104 is mounted on the lock core body 105. When the lock core body 105 rotates, it drives the shifting block 104 to move within the trajectory of the locking pin 101. At the same time, it also drives the locking pin 101 to move telescopically.

A first compression spring 132 is pre-installed between the first lock core head 134 and the first end cap 131. A groove is provided at the top of the lock core body 105 of the horizontal locking device 10. The bottom of the first lock core head 134 is inserted into the groove of the lock core body 105. By pressing down the first end cap 131 with a special key and rotating the first lock core head 134, the rotation of the first lock core head 134 drives the lock core body 105 to rotate together, thereby driving the shifting block 104 to move within the trajectory of the locking pin 101. After pulling out the special key, the first end cap 131 is reset under the action of the first compression spring 132.

[0032] As shown Figure 8 in FIG. 4, the emergency unlocking switch assembly 8 includes an emergency unlocking switch 81 and an emergency unlocking mounting plate 82. The emergency unlocking switch 81 is connected to the emergency unlocking mounting plate 82 by fasteners, and the emergency unlocking mounting plate 82 is connected to the frame assembly 6 by fasteners.

[0033] As shown Figure 9As shown in the figure, the emergency unlocking lock core assembly 12 includes a second end cover 121, a second compression spring 122, a second lock core head 123, a mounting seat 124, a second flange 125, a push rod assembly 126, a lock body 127, a push rod bracket 128, and a second cam 129. The second flange 125 is connected to the pattern steel plate assembly 1 by screws; the second lock core head 123 is connected to the second flange 125 by a snap ring; the second compression spring 122 is pre-installed between the second end cover 121 and the second lock core head 123; the mounting seat 124 is connected to the pattern steel plate assembly 1 by screws; the lock body 127 is connected to the mounting seat 124 by nuts. The second cam 129 is disposed below the lock body 127 and is coaxially connected to the lock body 127; the push rod assembly 126 is installed on the frame assembly 6 and penetrates through the push rod bracket 128; operating the second lock core head 123 to rotate with a special key drives the second cam 129 to rotate. The second cam 129 pushes the push rod assembly 126 to perform telescopic movement in the push rod bracket 128, thereby unlocking the motor 72. At the same time, the second cam 129 triggers the emergency unlocking switch assembly 8 during the rotation process.

[0034] As Figure 10 and Figure 11 shown in the figure, the platform compensator further includes a disconnect switch assembly 18. The disconnect switch assembly 18 includes a disconnect switch 181, an isolation lock core 182, a flange nut 183, a support plate 184, a first cam 185, and an angle iron 186. The disconnect switch 181 is connected to the support plate 184 by the angle iron 186. Both ends of the angle iron 186 are fixedly connected to the disconnect switch 181 and the support plate 184 by screws; the isolation lock core 182 and the cam 185 are both connected to the support plate 184 by the flange nut 183 and screws. The isolation lock core 182 is located above the cam 185. The flange nut 183 is connected to the vehicle body by screws. Operating the isolation lock core 182 to rotate with a special key drives the cam 185 to rotate coaxially, thereby triggering the disconnect switch 181; when the disconnect switch assembly 18 is triggered, the disconnect switch assembly 18 sends a switch signal to the controller 19, and the controller 19 bypasses the platform compensator, so that the platform compensator no longer receives external electrical signals.

[0035] As Figure 1 、 Figure 2 、 Figure 4 and Figure 7 shown in the figure, when the vehicle stops at a high platform, the platform compensator is in the Figure 1 horizontal locked state shown in the figure. The platform compensator is interlocked with the door. When the platform compensator receives the door opened-in-place signal, the motor 72 drives the gear 74 to rotate forward. The forward rotation of the gear 74 drives the rack 73 to move forward. The rack 73 pulls the movable pedal assembly 4 associated with the connecting plate 75 to move to the set position and stays at this position;

[0036] When the platform compensator receives the door closing signal instruction, if the horizontal locking switch assembly 9 is detected to be effective, the motor 72 drives the reverse drive gear 74 to rotate. The reverse rotation of the gear 74 drives the rack 73 to move backward. When the rack 73 pulls the movable pedal assembly 4 associated with the connecting plate 75 to move to the initial position, the received position switch assembly 11 is triggered, and the movable pedal assembly 4 remains in this initial position. At the same time, the received position switch assembly 11 transmits the received position signal to the door system, and the door system performs the door closing action.

[0037] As Figure 9 shown, when the platform compensator cannot be retracted, operate the emergency unlocking lock core assembly 12 with a special key to unlock the brake of the motor 72, and then the movable pedal assembly 4 can be manually pushed to the retracted position.

[0038] As Figures 3 to 6 shown, when the vehicle is parked at a low platform, the platform compensator is in the Figure 1 horizontal locking state as shown. Operate the horizontal lock core assembly 13 with a special key, the lock pin 101 disengages from the lock catch 3, the horizontal locking switch assembly 9 is released, and the platform compensator is turned up to the vertical locking position under the action of the variable damping gas spring assembly 15 and is locked by the vertical locking device 14. Due to the effective damping at the end of the variable damping gas spring assembly 15, the end movement impact can be reduced. When the platform compensator is in the vertical locking position, it will no longer respond to the door opening and closing instructions of the vehicle door system.

[0039] As Figures 10 to 11 shown, when the vehicle is operating along a high platform and the platform compensator fails and cannot be used, operate the platform compensator disconnect switch assembly 18 to the "isolation" position. The disconnect switch assembly 18 sends a switch signal to the controller 19, and the controller 19 bypasses the platform compensator. The local platform compensator will no longer receive the local door system signal, and the opening and closing actions of the local door system will no longer be affected by the platform compensator. After the fault is eliminated, operate the disconnect switch assembly 18 to the "reset" position, and the local platform compensator will resume receiving the local door system signal and perform extension and retraction actions along with the opening and closing of the door system.
