[0036] The other end of the first L-shaped connecting rod 4 is hingedly connected with one end of a second connecting rod 5;

[0037] The other end of the second connecting rod 5 is hingedly connected with the polished rod structure 1; wherein,

[0038] The cylinder component 3 is configured to, when the cylinder thereof is extended and retracted, cooperate with the first L-shaped connecting rod 4 and the second connecting rod 5 to drive the portal slider 2 to slide on the polished rod structure 1.

[0039] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0040] Referring to Figs. 1-3 As shown in the drawings, the embodiments of the present application provide a kind of full pneumatic mechanical self-locking high-speed train outer door driving device, the driving device includes:

[0041] Said polished rod structure 1 is configured with hoisting structure 10;

[0042] Door frame slider 2 is slidably arranged on the polished rod structure 1;

[0043] Cylinder component 3, one end of the cylinder component 3 is connected with base structure 30, the other end of the cylinder component 3 is hinged with one end of first L-shaped connecting rod 4;

[0044] The turning point of the first L-shaped connecting rod 4 is rotatably arranged at the fixed point of the polished rod structure 1 and the hoisting structure 10;

[0045] The other end of the first L-shaped connecting rod 4 is hinged with one end of second connecting rod 5;

[0046] The other end of the second connecting rod 5 is hinged with the polished rod structure 1;Wherein,

[0047] The cylinder component 3 is configured to cooperate with the first L-shaped connecting rod 4 and the second connecting rod 5 when the cylinder of the cylinder component 3 is extended and retracted, to drive the door frame slider 2 to slide on the polished rod structure 1.

[0048] It should be noted that the door frame slider 2 is used to be matched with the outer door of the high-speed train, so as to drive the outer door of the high-speed train by moving.

[0049] If necessary, the cylinder component 3 can be a driving cylinder.

[0050] It should be noted that the technical scheme of the embodiments of the present application includes the opening process, the closing process and the locking state when the closing process is completed.

[0051] The embodiments of the present application combine the driving cylinder and the connecting rod mechanism, adopt the characteristics of ingenious connecting rod mechanism self-locking, and do not need air pressure to ensure the locking of the outer door when the outer door is closed. During the opening and closing process of the outer door, the extension and retraction of the cylinder are used to realize the opening and closing actions of the outer door.

[0052] It should be noted that the technical scheme of the embodiment of the present application can be used to drive the outer door of a high-speed train. The outer door adopts a connecting rod mechanical self-locking mode to complete the outer door locking function when the outer door is closed. Even when the vehicle air pressure is insufficient, the vehicle closing safety and reliability is ensured, and the safety of the vehicle outer door is improved. At the same time, the whole pneumatic control only has two actions of the extension and retraction of the cylinder to control the opening and closing of the outer door. The two actions are simple and reliable, and the transition is smooth. At the same time, when the cylinder is retracted to drive the outer door to close in place, the connecting rod mechanism is used to complete the outer door locking. The electric locking mechanism is not needed to assist in locking the door. There are advantages of less control components, low failure rate, high reliability and the like.

[0053] The problem of the outer door driver relying on pneumatic control is solved. When the train air pressure is insufficient, the vehicle outer door closing is unreliable, which affects the train operation and causes safety accidents.

[0054] The extension and retraction of the cylinder realize the opening and closing actions of the outer door. The self-locking of the connecting rod mechanism realizes the locking action of the outer door, and ensures the reliable locking of the outer door.

[0055] Further, the angle of the turning point of the first L-shaped connecting rod 4 is a right angle.

[0056] Further, the light rod structure 1 is horizontally arranged.

[0057] Further, the extension and retraction direction of the cylinder component 3 is horizontal.

[0058] Further, the cylinder component 3 is configured to drive the door frame sliding block 2 to slide towards the fixed point of the light rod structure 1 and the hoisting structure 10 in cooperation with the first L-shaped connecting rod 4 and the second connecting rod 5 when the cylinder of the cylinder component 3 is extended.

[0059] Further, the cylinder component 3 is configured to drive the door frame sliding block 2 to slide away from the fixed point of the light rod structure 1 and the hoisting structure 10 in cooperation with the first L-shaped connecting rod 4 and the second connecting rod 5 when the cylinder of the cylinder component 3 is retracted.

[0060] Of course, in order to further improve the technical universality, the cylinder component 3 can be replaced by a lead screw transmission mode or a linear motor drive.
