The output shaft of the driving motor 12 is connected to the end position of the two-way screw rod 9. When the boarding ladder 1 is docked with the aircraft cabin door, the driving motor 12 is started to drive the two-way screw rod 9 to rotate, and the two-way screw rod 9 drives the two guide seats 10 to move relative to each other, and the two guide seats 10 drive the two first connecting frames 18 to move relative to each other. The two second connecting frames 19 arranged in cooperation with the two first connecting frames 18 change the inclination angle of the two guide rods 11. When the inclination angle of the two guide rods 11 changes, the fixed seat 13 can be pushed to move laterally, so that the two rectangular movable openings 5 ​​and the two guide brackets 6 arranged in cooperation with the fixed seat 13 drive the extended rain shield 4 to move laterally until the end position of the limit plate 7 installed on one side of the extended rain shield 4 is in contact with the aircraft, so that under the action of the extended rain shield 4 and the rain shield 2, it can play a better rainproof role when passengers and staff get on and off the aircraft.

[0026] In a specific embodiment, a symmetrically arranged mounting bracket 3 is fixedly connected to the top of the boarding ladder 1, and the rain shield 2 is fixedly connected to the top positions of the two mounting brackets 3.

When the fixing seat 13 moves laterally, it drives the connecting plate 14 to move laterally, and the connecting plate 14 drives the limiting plate 7 to move laterally until the end position of the limiting plate 7 is in contact with the aircraft. At this time, under the action of the two sliding rods 15, the two connecting rods 16 and the two connecting springs 17, the contact process between the limiting plate 7 and the aircraft can be buffered.

[0027] The implementation principle of the passenger ladder canopy that automatically fits the aircraft in this embodiment is as follows:

[0028] When the passenger ladder vehicle travels to the bottom of the aircraft, the boarding ladder 1 is raised by its own power device, and the boarding ladder 1 is docked with the aircraft cabin door, so that passengers and staff can get on and off the aircraft through the boarding ladder 1. When the boarding ladder 1 is docked with the aircraft cabin door, the driving motor 12 is started to drive the bidirectional screw rod 9 to rotate, and the bidirectional screw rod 9 drives the two guide seats 10 to move relative to each other. The two guide seats 10 drive the two first connecting frames 18 to move relative to each other. The two second connecting frames 19 arranged in cooperation with the two first connecting frames 18 change the inclination angles of the two guide rods 11. When the inclination angles of the two guide rods 11 change, It can push the fixing seat 13 to move laterally, so that the two rectangular movable openings 5 ​​and the two guide brackets 6 arranged in cooperation with the fixing seat 13 drive the extended canopy 4 to move laterally, and at the same time, the fixing seat 13 drives the connecting plate 14 to move laterally, and the connecting plate 14 drives the limiting plate 7 to move laterally until the end position of the limiting plate 7 fits with the aircraft. At this time, under the action of the two sliding rods 15, the two connecting rods 16 and the two connecting springs 17, a buffering effect can be played on the fitting process of the limiting plate 7 and the aircraft, so that under the action of the extended canopy 4 and the rain shield 2, it can play a better rain shielding effect when passengers and staff get on and off the aircraft.
