(2) Because the door plant and the connection of drive utilize the cantilever to connect the last front portion at the door plant, in order to guarantee this cantilever not to interfere the automobile body, then the width of door plant has just been restricted to this mechanism, has just so restricted the opening width of train. Affecting the size of the vehicle interior components and the comfort of the passengers. (3) Because the external swing type sliding plug door is opened towards the outside of the train, when the train runs at a high speed and the two trains meet, the door plate can fall off due to the influence of large air pressure fluctuation. The safety of the train is influenced, and the requirement on the main locking mechanism and the auxiliary locking mechanism is high.

When a train meets at a high speed or passes through a tunnel, the rubber strip can be separated from the train body due to the influence of negative pressure, so that air leakage occurs. This can result in loud noise and affect passenger comfort. (5) The external swing type sliding plug door system is complex in overall structure and is controlled by a motor, so that the requirement on an electrical system is high (embedded software development is involved), the cost is high, and the maintenance is inconvenient.

The defects of the prior art are as follows: (1) the whole structure is complex, the occupied train space is large, and the cost is high. (2) The installation and debugging requirements of the components are high, and the subsequent maintenance is difficult. (3) The whole action is controlled by the EDCU, and the requirement on an electrical system is high; and the safety cannot be guaranteed during the compression. (4) The scheme has high requirements on processing and use and is difficult to realize commercial application (no door system is commercially available at present). (5) The door plate moves in a middle supporting mode, a guide part is not arranged at the bottom of the door plate, and the door plate swings during actual operation, so that the safety and the reliability of the mechanism part are influenced.

The opening and closing process of the vehicle door is as follows:
(1) The door closing action process:
high-pressure air (oil) enters the first piston cylinder 2-1 through the reversing solenoid valve 3 and a pipeline, then the first piston rod 2-1-2 pushes the two door panel connecting pieces 12-1 (one door panel 12 is arranged on the left and the right respectively to ensure the motion stability of the door panel 12) to move, the two door panel connecting pieces 12-1 are connected with the two upper pulley assemblies 5 through the supporting plate 12-2, and the upper pulley assemblies 5 are respectively arranged on the two upper guide rails 4.
In order to ensure that the outer surface of the door panel 12 is substantially flush with the outer surface of the vehicle body 13 after the door panel 12 is closed, the movement locus of the door panel 12 is in a plug-pull type. When the upper pulley assembly 5 moves on the upper guide rail 4, the door panel 12 moves along the track of the upper guide rail 4 through the two upper pulley assemblies 5, and the movement of the sliding plug is realized.
Specifically, when the first piston rod 2-1-2 extends, the door plate 12 is driven to move by the driving plate 6, the supporting plate 12-2 drives the upper pulley assembly 5 to move along the chute of the upper guide rail 4, when the upper pulley assembly 5 moves from the upper guide rail straight rail section 4-1 to the upper guide rail inclined rail section 4-2, the upper pulley assembly 5 rotates by 60 degrees relative to the supporting plate 12-2, the chute of the upper guide rail inclined rail section 4-2 exerts an acting force on the upper pulley assembly 5 towards the outside of the vehicle body 13, and the door plate 12 and the clamping plate 6-1 can simultaneously move towards the outside of the vehicle body 13 relative to the first piston rod 2-1-2 because the clamping plate 6-1 is provided with the driving chute 6-1-1 for mounting the first piston rod 2-1-2. The clamping plate 6-1, the parallel plate 6-2, the supporting plate 12-2 and the door plate connecting piece 12-1 are fixedly connected, the door plate 12 and the door plate connecting piece 12-1 are fixedly connected and arranged in parallel with the outer surface of the vehicle body 13, so that the door plate 12 is static relative to the clamping plate 6-1, and the door plate 12 is always parallel to the outer surface of the vehicle body 13 under the combined action of the driving mechanism 2 and the upper pulley assembly 5 because the clamping plate 6-1 and the first piston rod 2-1-2 move synchronously along the axial direction of the first piston rod 2-1-2.
When the upper pulley assembly 5 moves to the final position along the upper guide rail 4, namely the plugging movement is finished, the outer surface of the door panel 12 is basically flush with the outer surface of the vehicle body 13, but a gap is still formed at the moment, and the scheme adopts four pressing devices 8 to press the door panel 12.
The pressing devices 8 are fixed on a mounting plate of the vehicle body 13 by screws, and the four pressing devices 8 are symmetrical left and right and up and down, so that the inner side surfaces of the door panels 12 can be effectively contacted with the pressing devices 8. When high-pressure gas (oil) enters the second piston cylinder 8-1, the second piston rod 8-1-2 extends out and drives the connecting rod 8-2 to rotate around the connecting rod hinge shaft 8-2-1, so that the pressing motion can be realized. Through the compressing process, the outer surface of the door panel 12 is flush with the outer surface of the vehicle body 13, and the door closing action is completed.
(2) The door opening action process:
in the process, the gas (oil) path is reversed through the reversing electromagnetic valve 3, so that the first piston rod 2-1-2 and the second piston rod 8-1-2 move towards the door opening direction, and other actions refer to the door closing action process, so that the door opening action can be realized.
The movement of the whole door panel 12 is carried out in the vehicle body 13, so that the door panel 12 is prevented from being separated from the vehicle body 13 due to external load, and the driving safety is ensured.
The above embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit of the above-described embodiments should be included in the protection scope of the technical solution.
