[0021] See also Figure 1-3 As shown, a carriage docking device includes an arc plate 1, a slide rail 2, a plug-in plate 4, a ball head 7, a buffer spring 11, a gear 12 and a rotary damper 13. Two slide grooves 110 are symmetrically provided on the plane of the arc plate 1, and side guide grooves 210 are provided on the inner sides of the two slide grooves 110. The end face of one end of the slide rail 2 is connected to the end wall of one end of the slide groove 110 through the buffer spring 11, and the slide rail 2 is slidably installed in the slide groove 110. A plug-in plate 4 is slidably installed between the two side guide grooves 210, and the middle part of the plug-in plate 4 is connected to the U-shaped plate 6 through a connecting plate 5. The two ends of the groove 510 located at the bottom front end of the connecting plate 5 are respectively connected to one end of two limiting short blocks 511 through a rotating shaft equipped with a torsion spring. The arc tooth surface of the arc plate 1 is meshed with the gear 12, and the gear 12 is connected between the two rotary dampers 13 through a connecting shaft.

[0022] Furthermore, the side guide groove 210 is connected to the outer surface of the slide rail 2 through a channel, and an oil cylinder 3 is installed at the outer end of the channel. The output end of the oil cylinder 3 is extended and inserted into the slot located on the side wall of the plug-in board 4 and plugged together.

[0023] Furthermore, connecting ring seats 8 are installed on both sides of the inner wall of the U-shaped plate 6, and a same ball head member 7 is rollingly connected between the two connecting ring seats 8, and the ball head member 7 is connected to one end of the connecting ring seat 8.

[0024] Furthermore, a stud 9 is installed inside the screw hole on the ball head 7 , and both ends of the stud 9 pass through the circular holes 610 located on the U-shaped plate 6 respectively.

[0025] Furthermore, two rotation dampers 13 are provided, and the two rotation dampers 13 are respectively mounted on the inner side walls of the U-shaped connecting frame 14 .

[0026] Furthermore, both ends of the U-shaped connecting frame 14 are rotatably connected to shafts located at the centers of both sides of the arc plate 1 .

[0027] Furthermore, one side of the limiting short block 511 is in contact with one end of the slide rail 2 .

[0028] Furthermore, the slide rail 2 is initially in an inclined state, and a buffer displacement structure is formed between the slide rail 2 and the arc plate 1 .

[0029] Working principle: Taking the U-shaped connecting frame 14 connected to the rear end of the front car and the flange shaft 10 connected to the front end of the rear car as an example, the front end of the rear car is inserted into the two side guide grooves 210 located on the inner sides of the two slide rails 2 through both sides of the plug-in plate 4 connected by the flange shaft 10, ball head 7, U-shaped plate 6, and connecting plate 5. At the same time, all the oil cylinders 3 are extended and their output ends are inserted into the slots located on the side walls of the plug-in plate 4. Then, the limiting short block 511 is reset by the torsion spring and contacts the corresponding end of the slide rail 2, thereby completing the connection between the front and rear cars. When the traction vehicle stops or moves when braking, due to the inertia of the carriage, another effect of the connection between the front and rear carriages is that the rear carriage applies a forward thrust or backward pulling force to the connected plug-in board 4, causing the connected slide rail 2 to move along the slide groove 110, achieving the effect of compressing or extending the connected buffer spring 11. If the buffer spring 11 is about to be compressed by one-third, the arc plate 1 begins to rotate counterclockwise or clockwise under the force, and the plug-in board 4 continues to move forward or backward under the force at this time. The rotation damper 13 connected on both sides of the gear 12 can form a resistance to the counterclockwise rotation of the arc plate 1 that is meshed with the gear 12 for transmission, thereby playing a buffering role. Compared with the existing technology, the difference is that: the arc plate 1 that can be rotated under force is used to adjust the movement direction of the slide rail 2 to which it is slidably connected, and the end of the slide rail 2 is connected to the buffer spring 11 located inside the slide groove 110, which is conducive to dispersing and offsetting the horizontal force of the rear end car in different changing directions, and leaving a buffer space for the car to travel in the horizontal direction in an emergency reverse. At the same time, the gear 12 installed between the two rotary dampers 13 forms a reverse buffer resistance to the meshed arc plate 1, which improves the energy dissipation and buffering effect at the car joint, greatly reduces the impact intensity of pulling and pushing between the cars, and the traction travel between the cars is smoother.
