The locking and unlocking assembly comprises an unlocking swing rod 4, a left swing rod 5, a right swing rod 9, a pull rod 7 and a joint bearing connecting rod 16.
One end of the unlocking swing rod 4 is connected with a motor swing rod driving component 17 through a joint bearing connecting rod 16, the other end of the unlocking swing rod 4 is fixed on the bearing cross beam 8 through a supporting shaft 29, and the unlocking swing rod 4 can swing around the supporting shaft 29. The motor swing rod driving component 17 drives the unlocking swing rod 4 to swing around the supporting shaft 29 through the joint bearing connecting rod 16.
The left swing rod 5 is shaped like a Chinese character 'ren', and has three sides of vertical, left falling and right falling. Wherein, the left falling edge and the right falling edge of the left swing rod 5 are respectively provided with a long slotted hole. The junction of three sides of the left swing link 5 is fixed on the bearing beam 8 through a left rotating shaft 30 and can rotate around the left rotating shaft 30. An unlocking swing rod bearing 19 penetrates through the left-side long slotted hole of the left swing rod 5, and the unlocking swing rod bearing 19 connects the left swing rod 5 and the unlocking swing rod 4 together. A left curved roller bearing 18 is arranged in the right-falling side length slotted hole of the left swing rod 5 in a penetrating way, and the left curved roller bearing 18 is fixed on an upper supporting bottom plate 20. When the motor in the motor swing rod driving component 17 rotates, the power output by the motor drives the unlocking swing rod 4 to swing around the supporting shaft 29 through the knuckle bearing connecting rod 16, and the unlocking swing rod 4 drives the left swing rod 5 to move around the left rotating shaft 30 through the unlocking swing rod bearing 19.

The left and right swing rods 5 and 9, the pull rod 7, the left and right knuckle bearings 28 and 281, and the left and right rotating shafts 30 and 301 form a four-bar linkage structure.
In order to enable the left and right swing rods 5 and 9 to synchronously move, the left knuckle bearing 28 and the right knuckle bearing 281 are provided with external threads in opposite directions. And internal threads corresponding to the external threads of the left knuckle bearing 28 and the right knuckle bearing 281 are respectively arranged at two ends of the pull rod 7. The design can ensure the synchronous swing of the left swing rod and the right swing rod.
As shown in fig. 3A and 3B, a line a represents a line of a position where the unlocking rocker bearing 19 is actually located, and a line B represents a line of a locking dead point position. The centers of rotation circles of the unlocking swing rod 4, the left swing rod 5 and the unlocking swing rod bearing 19 form a right triangle at the position of a locking dead point. When the door leaf of the sliding plug door is in a closed state, the unlocking swing rod bearing 19 is positioned at a position (see fig. 3A) larger than 90 degrees, as long as the position of the unlocking swing rod 4 is not moved, the left swing rod 5 is limited by the unlocking swing rod 4 and the unlocking swing rod bearing 19 under the action of force F when a passenger pushes the door, a four-link mechanism formed by the left swing rod and the right swing rod is locked, and the door leaf cannot be opened; when the door is opened, the motor swing rod driving component 17 pulls the unlocking swing rod 4 to swing around the supporting shaft 29 through the joint bearing connecting rod 16, so that the unlocking swing rod bearing 19 is driven to slide in the long groove hole of the left swing rod 5, after the unlocking swing rod 4 slides through the line B at the locking dead point position, a triangle formed by the rotating circle centers of the unlocking swing rod 4, the left swing rod 5 and the unlocking swing rod bearing 19 becomes a non-right-angled triangle, and a four-link mechanism formed by the left swing rod and the right swing rod can rotate and swing under the action of force F, so that the door leaf of the sliding-plug door is opened. This is the basic principle of the present invention for locking and unlocking.
As shown in fig. 4 and 5, the motor swing link driving mechanism 17 of the present invention includes a motor 25, a planetary gear 22, and a bevel gear reducer 21, which are connected in sequence. The bevel gear output shaft 26 of the bevel gear reducer 21 is directly connected with the inner hole of the toothed belt wheel, and torque is transmitted by using a flat key. A driving swing rod 23 is arranged on the shell of the planetary reducer 22, the driving swing rod 23 is rotatably connected with the joint bearing connecting rod 16, a support member 27 on two sides of the driving swing rod 23 is provided with a limit stop 24, and a bearing and an anti-wear washer are arranged in the support member 27 to ensure the relative rotation of the motor shell and the rotor. The motor is a direct current brushless motor, and the planetary reducer is a two-stage planetary reducer.
When the motor 25 normally rotates, the power is directly transmitted to the output shaft 26 of the bevel gear reducer 21, and the toothed belt 15 is driven to rotate, so that the door opening and closing function can be realized. When the door leaf is just opened, the motor 25 does not rotate because of overlarge mechanism resistance, the motor shell rotates reversely to drive the driving swing rod 23 to swing, and the driving swing rod 23 drives the unlocking swing rod 4 to unlock; when the door leaf is closed soon, the shell of the motor 25 rotates relatively again because the contact resistance of the door leaf rubber strips and the like is increased, the driving swing rod 23 is driven to drive the unlocking swing rod 4 to swing reversely, and therefore the unlocking swing rod bearing 19 swings past the locking dead point position to enter a locking area. This is that the utility model uses the reaction moment of the motor housing relative to the rotor to perform locking and unlocking control. Meanwhile, the rotary power of the motor is transmitted to the toothed belt 15, the toothed belt moves forward and backward to drive the sliding block connected with the toothed belt to move, and therefore the door leaf of the sliding plug door connected with the sliding block is driven to move in the opening and closing direction.
