[0042] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly. In addition, the descriptions involving "preferred", "suboptimal" and the like in the present application are only used for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features with "preferred", "suboptimal" can be explicitly or implicitly included at least one of the features.

[0043] Embodiment I:

[0044] As Figures 1-2 A safety shoe automatic launching device is arranged on the floor in front of the operating window of the boarding bridge connection, comprising a protective cover 1 arranged on the floor of the boarding bridge connection, a safety shoe body 2 arranged in the protective cover 1 for supporting the opened aircraft door and detecting the descending distance of the aircraft relative to the boarding bridge during the boarding process, and a driving device 3 arranged on the floor of the boarding bridge connection and controlled by the boarding bridge system to drive the safety shoe body 2 to extend or retract from the protective cover 1. A driving arm 4 is connected between the safety shoe body 2 and the rotating end of the driving device 3.

[0045] As Figure 6 shown, the safety shoe body 2 comprises a safety shoe tray 21 hingedly connected to the driving arm 4. A pressure sensor 22 is arranged in the safety shoe tray 21 for detecting the pressure of the aircraft door. A rubber sheath 23 is arranged on the upper part of the safety shoe tray 21. A flexible edge plate 24 is arranged at the end of the safety shoe tray 21 away from the driving arm 4. A sliding device is arranged at the bottom of the safety shoe tray 21. The flexible edge plate 24 and the rubber sheath 23 can avoid scratching the aircraft and forming hard contact to cause damage to the aircraft.

[0046] As Figures 3-6 shown, the rotating end of the driving device 3 is arranged vertically downward, and the safety shoe body 2 is driven by the driving arm 4 to make circular motion. The driving arm 4 is not telescopic. The sliding device comprises two groups of arc-shaped roller groups 25 for making the safety shoe body 2 make circular motion with the driving arm 4. One group of arc-shaped roller groups 25 is arranged on the bottom surface of the safety shoe tray 21 near the driving arm 4, and the other group of arc-shaped roller groups 25 is arranged on the bottom surface of the safety shoe tray 21 away from the driving arm 4.

[0047] Under the driving action of the driving device 3, the driving arm 4 swings the safety shoe body 2 to the working position under the aircraft door around the rotation center of the output shaft of the driving device 3. For this reason, the arrangement of the two groups of arc-shaped roller groups 25 is as shown in Figure 4 , which is installed around the rotation center and in the tangential direction of the radius.

[0048] In this case, the hinged connection between the safety shoe body 2 and the driving arm 4 and / or the driving device 3 and the driving arm enables the safety shoe body 2 to move in the height direction.

[0049] Specifically, as Figures 3-6As shown, the rotating end of the drive device 3 is connected to the connecting arm section 5, and the safety boot body 2 is connected to the slewing joint 6. The two ends of the drive arm 4 are hinged to the connecting arm section 5 and the slewing joint 6 respectively, so that the safety boot body 2 can move along the height direction. At the same time, the boarding bridge docking port bottom plate is provided with a mounting seat 7 inside the protective cover 1. The drive device 3 is fixed on the mounting seat 7, which provides sufficient degrees of freedom for the entire safety boot deployment device. When the docking port swings the floor and the bottom plate is at different spatial angles, it ensures that the safety boot body 2 has good contact with the floor.

[0050] After the boarding bridge is in contact with the aircraft fuselage, its automatic leveling mechanism extends and approaches the aircraft. The output shaft of the safety shoe deployment device rotates the safety shoe to a position below the aircraft door, thus completing the boarding bridge docking with the aircraft. During passenger and baggage / cargo loading and unloading, the aircraft's altitude will change due to variations in its load. Under normal circumstances, a step distance of less than 20mm is adjusted by the boarding bridge leveling device under the action of the boarding bridge lifting system to achieve relative following motion with the aircraft. If the boarding bridge leveling mechanism malfunctions or a bug in the program causes the door to approach the arrival gate floor abnormally, the pressure sensor 22 in the safety shoe body 2 will receive pressure from the aircraft door, detect the abnormal condition of the aircraft door, and send a detection signal to the boarding bridge control system. The boarding bridge will then descend urgently at a speed range of 0.1m / s to 0.2m / s, and the movement should stop after 1 second. If the boarding bridge is continuously triggered, the cumulative descent distance should not exceed 400mm; otherwise, the boarding bridge descent function should be locked and an alarm should be triggered to protect the aircraft's safety as much as possible.

[0051] Example 2:

[0052] In Embodiment 1, the safety boot with rollers is only suitable for moving along the tangent of the rollers. If the safety boot can move radially around the drive device shaft, the safety boot delivery device can be arranged more flexibly and the safety boot can be more easily placed in the best working position.

[0053] In Example 2, the safety boot's movement trajectory can be either circular motion around the drive unit's axis or radial extension / retraction motion. Alternatively, it can perform both circular and extension / retraction motions simultaneously in a composite motion.

[0054] Therefore, as Figures 7-12 As shown, the difference between Embodiment 2 and Embodiment 1 is that the drive arm 4 is an electrically controlled telescopic arm, and the sliding device is a universal ball assembly to adapt to changes in movement.

[0055] like Figures 7-8 As shown, the addition of radial movement function to the safety boot expands its range of motion, making the entire device relatively compact and small.

[0056] As Figures 11-12 shown, the electric control telescopic arm includes a telescopic arm including a sleeve 41, one end of the sleeve 41 is provided with a tail hinge 42 articulated with the rotating end of the driving device 3, the other end of the sleeve 41 is provided with a front cover 43, the sleeve 41 is sequentially provided with a telescopic arm motor 44, a speed reducer 45, a bearing 46, a first buffer limiting block 47, a guide ring 48 which can slide in the sleeve 41, a transmission nut 49, a driving screw 410, a telescopic rod 411, a second buffer limiting block 412 between the tail hinge 42 and the front cover 43, the rotating end of the telescopic arm motor 44 is connected with the speed reducer 45, the rotating end of the speed reducer 45 passes through the bearing 46, the first buffer limiting block 47, the guide ring 48 and is connected with the driving screw 410, the transmission nut 49 is fixedly connected with the guide ring 48 and is sleeved on the driving screw 410, one end of the telescopic rod 411 is connected with the transmission nut 49 and the other end is articulated with the safety shoe body 2 outside the front cover 43, the guide ring 48 guides the transmission nut 49 to slide in the sleeve 41 when the driving screw 410 rotates to drive the telescopic rod 411 to extend or retract, the first buffer limiting block 47 and the second buffer limiting block 412 limit the sliding distance of the transmission nut 49 in the sleeve 41, when the telescopic arm extends, the telescopic arm motor 44 drives the speed reducer 45 to rotate, the speed reducer 45 drives the driving screw 410 to rotate, the transmission nut 49 slides on the driving screw 410 under the action of the guide ring 48, thereby driving the telescopic rod 411 connected with the transmission nut 49 to extend or retract in the sleeve 41.

[0057] The safety shoe is extended with the telescopic arm, the pressure sensor 22 in the safety shoe is also away from the center of rotation of the driving device 3, so a telescopic cable 413 with variable length is needed, specifically, the pressure sensor 22 is connected with the telescopic cable 413, the other end of the telescopic cable 413 extends out through the telescopic rod 411, the driving screw 410 and the tail hinge 42 and is connected with the boarding bridge system control.

[0058] As Figures 9-11 shown, the electric control telescopic arm has hinge points at both ends, plus the rotation joint on the safety shoe, so that the safety shoe has corresponding degrees of freedom to adapt to the change of the inclination angle of the boarding bridge and the change of the floor space angle caused by the leveling of the oscillating plate of the aircraft docking port.

[0059] The structure exploded view of the second embodiment is shown in Figure 12 , wherein the material of the rolling ball can be engineering plastic or stainless steel, because the rolling ball is supported by a layer of rolling balls, so it can prevent corrosion and rust and move smoothly.

[0060] As Figure 13 shown, the universal ball assembly 26 of the safety shoe can also be replaced by a universal wheel assembly 27; as Figure 14As shown, a slider 28 made of oil-lubricated nylon or similar material with a low coefficient of friction can also be used instead.

[0061] Example 3:

[0062] like Figures 15-18 As shown, in Embodiment 3, the drive device 3 is located under the floor of the boarding bridge connection area. The output shaft of the drive device 3 extends out of the floor, driving the drive arm to rotate or driving the telescopic arm to rotate. It can also directly drive the electric push rod to rotate. The safety boot makes longitudinal feeding movement under the drive of the electric push rod. Because the drive device 3 is located under the floor, the appearance is simple.

[0063] like Figure 19 As shown, the drive device 3 of Embodiment 3 includes a housing 31, with a tail cover 32 connected to the lower end of the housing 31. Inside the housing 31, from bottom to top, there are a drive module 33 controlled by the boarding bridge system, a drive motor 34, a reducer 35, and a bearing 36. The control output terminal of the drive module 33 is connected to the drive motor 34, and the rotating end of the drive circuit 34 is connected to the reducer 35. The drive shaft of the reducer 25 passes through the bearing 36 and extends out of the housing 31. The drive device 3 can be equipped with a worm gear reducer motor, a right-angle reducer motor, etc.

[0064] like Figures 15-18 As shown, the annular mounting base 7 is sleeved on the outside of the housing 31 of the drive unit 3. The drive unit 3 is installed on the circular hole opened in the boarding bridge dock floor through the annular mounting base 7, and the output shaft of the drive unit 3 extends out of the floor. It is then hinged to the drive arm, electric telescopic arm or electric push rod through the connecting arm joint 5, which serves as the drive head, making the structure more compact and tighter.

[0065] like Figures 17-18 As shown, an electric push rod is used as the telescopic arm, and the drive device 3 is selected to be parallel or perpendicular to the extension direction. The appearance is not as beautiful and simple as the coaxial structure, but the stroke is longer. The choice can be made according to the space layout of the receiving port. At the same time, the telescopic cable 413 is set on the outside of the electric push rod and can change with the extension and retraction of the electric push rod.

[0066] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
