[0011] With reference to the drawings, the structure is that the load-bearing drive mechanism 2 is mounted on the upper part of the car body 1, and the door leaf 5 is connected to the load-bearing drive mechanism 2 through the door frame; the drive shafts 4 on both sides of the door are connected to the small hanger of the load-bearing drive mechanism 2 through hinge plates. After connecting with the locking device 6 in the middle and lower part of the door, they are installed on both sides of the car body 1. The rollers in the lower swing arm mechanism 7 are in the lower guide rail of the lower part of the car door; the outer operating device 8 and the outer operating device 8 installed on the outside of the car body 1 The emergency operating device 11 installed on the inner side of the vehicle body 1 is connected to the locking device 6 through a wire rope; the locking block on the door leaf 5 and the locking hook on the locking device 6 are arranged correspondingly.

[0012] The upper slide in the load-bearing drive mechanism 2 is installed on the base plate, the left and right short guide posts on both sides of the upper slide are respectively installed on the base plate through brackets, and a hanger is installed on each of the left and right short guide posts. Connect the rectangular rails.

[0013] The drive shafts 4 on both sides of the door are connected to the small hanger carrying the drive mechanism 2 through hinge plates, and are also connected to the auxiliary pressing device 3 in the upper middle of the door and installed on both sides of the vehicle body 1. The locks on the door leaf 5 are connected with each other. The lock hooks on the auxiliary pressing device 3 are correspondingly arranged.

[0014] The auxiliary pressing device bracket in the auxiliary pressing device 3 is equipped with an auxiliary pressing block, the gear on the auxiliary pressing block meshes with the reversing gear, the transmission shaft is connected with the adjusting gear, and the reversing gear meshes with the adjusting gear. , To achieve the auxiliary effect of locking and pressing the door.

[0015] The adjusting gear in the locking device 6 is connected with the transmission shaft 4, the adjusting gear is meshed with the reversing gear 13, the gear 14 with lock hook meshes with the reversing gear 13, and the gear 14 with lock hook meshes with the belt The jaw type electromagnetic clutch 12 of the gear plate is connected.

[0016] The isolation lock 9 is arranged on the door leaf 5 and is arranged corresponding to the lock block assembly on the vehicle body 1.

[0017] The external operating device 8 can realize manual unlocking and safe door opening in the case of abnormal operation.

[0018] The emergency operation device 11 realizes manual unlocking and safe door opening in the case of abnormal operation.

[0019] When working, the load-bearing drive mechanism 2 bears the full weight of the door leaf 5, and drives the door leaf 5 to open or close along the set movement track of the door leaf. The slideway, short guide post, square guide rail in the load-bearing drive mechanism 2 and the lower swing arm mechanism 7 at the lower part of the door work together to make the door leaf 5 move according to the set plug trajectory;

[0020] When the door is opened, the dog-type electromagnetic clutch 12 on the locking device 6 is energized to suck up the gear plate, the gear plate is disengaged from the gear 13, and the transmission shaft 4 drives the gear 13 to reverse the door to open;

[0021] When the door is closed, the drive shaft drives the gear on the auxiliary pressing device to rotate. When the door is closed to a certain position, the auxiliary pressing device presses the door, and the jaw type electromagnetic clutch 12 on the locking device 6 is de-energized to make the gear plate and The gear 13 meshes to make the gear 13 rotate in one direction, and the door continues to close under the drive of the door carrier. When the door is completely closed, the lock hook on the locking device 6 hooks the lock on the door leaf 5, using the gear plate and gear The one-way meshing of the gears prevents the gears from reversing so as to realize the locking function of the door system and ensure the sealing performance of the door system meets the requirements. After the door is closed, the door system restricts the door leaf 5 at 9 points. They are the lock hooks on the two sets of auxiliary pressing devices 3 hooking the locking pins on the door leaf; the lock hooks on the locking device 6 hooking The locking pin on the door leaf; the door carrying frame is rigidly connected with the door leaf 5; the rollers on the lower swing arm mechanism 7 on the two doors and the guide rail at the lower part of the door leaf 5 produce a binding force on the door leaf; the lock on the floor and the two door leaves The lower lock pins are connected, and the reliability and safety of the door system can be ensured through the above constraints.

[0022] The linear motion of the small hanger along the short guide post on the load-bearing drive mechanism is converted into the rotation of the transmission shaft through the hinge plate, thereby driving the auxiliary pressing device and the locking device to make active motions to realize the opening and closing and locking functions of the door .

[0023] The microprocessor-based door controller 10 can comprehensively and accurately control the action of the door, and at the same time complete safety protection functions such as intelligent obstacle detection, door isolation detection, and safety circuit. The electronic gate control unit also has automatic fault monitoring, diagnosis and reporting functions.
