[0068] As Figures 1 to 3 shown, Figures 1 to 3 The figures respectively show the schematic diagram of the docking device in three different perspectives according to the embodiments of the present application. The docking device according to the embodiments of the present application comprises a passage 100, a rotating platform 200 and a docking port 300.

[0070] The docking device according to the embodiments of the present application can be a boarding bridge or a boarding gangway, but is not limited thereto. When the docking device is a boarding bridge, the rotating platform 200 is a boarding platform, and the docking port 300 is a boarding port. When the docking device is a boarding gangway, the rotating platform 200 is a boarding platform, and the docking port 300 is a boarding port.

[0071] The docking device according to the embodiments of the present application, the rotating platform 200 comprises at least two docking interfaces 210 and an opening (not shown in the figure), and the at least two docking interfaces 210 and the opening are arranged along the circumferential direction of the rotating platform 200. The rotating platform 200 is rotatably connected to one end of the passage 100, so that any one of the docking interfaces 210 is docked with the passage 100. Each docking interface 210 is provided with a roller shutter door 500, and the roller shutter door 500 is opened or retracted in the vertical direction D relative to the docking interface 210. The docking port 300 is fixedly arranged on the rotating platform 200 and communicates with the opening.

[0072] The docking device of the embodiment of the present application is provided with at least two docking interfaces 210 on the rotating platform 200, and the roller shutter door 500 is opened or retracted along the vertical direction D. When docking is not needed, the roller shutter door 500 corresponding to each docking interface 210 is in a closed state. When docking is needed, the rotating platform 200 rotates relative to the passage 100 and drives the docking port 300 to rotate together until one of the docking interfaces 210 is docked with the passage 100. Moreover, the roller shutter door 500 corresponding to the docking interface 210 docked with the passage 100 is in an openable state, and the roller shutter door 500 corresponding to the docking interface 210 not docked with the passage 100 is in a closed and locked state. Compared with the side wall roller shutter door structure in the prior art, the roller shutter door 500 used in the docking device of the embodiment of the present application is designed to be opened or retracted along the vertical direction D, and the structure is simpler, more convenient to install, and lower in cost.

[0073] It can be understood that the roller shutter door 500 can use the product in the prior art, which will not be described here. In addition, the opening or retraction of the roller shutter door 500 can be manually pulled or electrically driven.

[0074] Please continue to refer to Figures 1 to 3 , the vertical direction D is parallel to the rotation axis L of the rotating platform 200. That is to say, when the rotating platform 200 is horizontally arranged, the movement direction of the roller shutter door 500 is vertically upward or vertically downward.

[0075] As an example, the rotating platform 200 can be cylindrical and include a bottom plate 201, a side plate 202 and a top plate 203, the bottom plate 201 and the top plate 203 are oppositely arranged in the vertical direction D, and the side plate 202 is arranged between the bottom plate 201 and the top plate 203 and connected with the bottom plate 201 and the top plate 203 respectively. The side plate 202 is perpendicular to the bottom plate 201 and the top plate 203. The bottom plate 201, the side plate 202 and the top plate 203 jointly enclose a space for passengers to pass through. The docking interface 210 and the opening are both arranged on the side plate 202, and the docking interface 210 and the opening are respectively communicated with the space of the rotating platform 200.

[0076] As shown in Figures 4 to 6 , Figures 4 to 6 respectively show the schematic diagrams when the rotating platform 200 is in different positions relative to the passage 100. The number of the docking interfaces 210 is odd. The positions of the rotating platform 200 relative to the passage 100 include a docking position and a parking position. In the parking position, the docking interface 210 located in the middle position among the odd number of docking interfaces 210 is docked with the passage 100, and the docking port 300 is linearly arranged with the passage 100. In the docking position, one of the remaining docking interfaces 210 is docked with the passage 100.

[0077] It can be understood that the parking position includes a state that the docking device is not used or is in a maintenance state.

[0078] In this embodiment of the invention, the number of interfaces 210 is three. For ease of explanation, the three interfaces 210 are defined as a first interface 210a, a second interface 210b, and a third interface 210c. Along the circumferential direction of the rotating platform 200, the first interface 210a is located between the second interface 210b and the third interface 210c. When the rotating platform 200 is in the stopped position relative to the channel 100, the first interface 210a is connected to the channel 100, and the connection port 300 is linearly arranged with the channel 100 (e.g., ...). Figure 4 During the process of switching the rotating platform 200 from the stop position to the docking position, the rotating platform 200 can rotate clockwise relative to the channel 100 until the second pair of interfaces 210b rotates to dock with the channel 100 (e.g., Figure 5 Of course, the rotating platform 200 can also rotate counterclockwise relative to the channel 100 until the third pair of interfaces 210c rotates to mate with the channel 100 (e.g., Figure 6 ).

[0079] It is understandable that when the rotating platform 200 is in the stopped position, the connection port 300 and the channel 100 may not be arranged linearly.

[0080] As an example, the three interfaces 210 and openings are evenly arranged along the circumferential direction of the rotating platform 200. That is, when the rotating platform 200 rotates from the stop position to the docking position, the rotating platform 200 rotates 90 degrees.

[0081] Of course, the three interfaces 210 and the opening along the circumferential direction of the rotating platform 200 can also be arranged non-uniformly, and the number of interfaces 210 can also be five, seven, nine or other numbers.

[0082] In other embodiments, the number of interfaces 210 may be even, not odd. That is, there may be two or more interfaces 210.

[0083] like Figures 7 to 9 As shown, Figure 7 The diagram shown is a cross-sectional view of the rotating platform 200 after being cut along the horizontal direction. Figure 8 What is shown is Figure 7 Sectional view of AA. Figure 9 What is shown is Figure 8 A magnified view of part X in the middle. Each interface 210 is also provided with a locking device 400. The locking device 400 is set on the rotating platform 200 and is used to lock the roller shutter door 500 in the closed state when the interface 210 is not connected to the channel 100. When the locking device 400 is squeezed by the channel 100 as the rotating platform 200 rotates, the roller shutter door 500 is unlocked.

[0084] In the embodiment, the number of the locking devices 400 is three, and each of the locking devices 400 is arranged beside the three docking interfaces 210. When the number of the docking interfaces 210 changes, the number of the locking devices 400 also changes accordingly.

[0085] It should be noted that the opening of the rotating platform 200 can be provided with the rolling shutter door 500, or can not be provided with the rolling shutter door 500. When the opening of the rotating platform 200 is provided with the rolling shutter door 500, the locking device 400 can also be arranged beside the rolling shutter door 500 corresponding to the opening.

[0086] Please refer to Figure 5 and Figure 6 When the second docking interface 210b and the third docking interface 210c on both sides of the first docking interface 210a are rotated to be docked with the passage 100, the locking device 400 corresponding to the second docking interface 210b or the third docking interface 210c is pressed by the passage 100, and the rolling shutter door 500 is unlocked. Since the other docking interfaces 210 are not docked with the passage 100, the locking devices 400 corresponding to the other docking interfaces 210 are not pressed by the passage 100, and the rolling shutter door 500 is locked.

[0087] When the locking device 400 locks the rolling shutter door 500, the rolling shutter door 500 cannot be retracted. That is, when the locking device 400 locks the rolling shutter door 500, the docking interface 210 corresponding to the rolling shutter door 500 is closed.

[0088] As shown in Figure 9 and Figure 10 , the passage 100 is provided with a pressing portion 110 at one end facing the rotating platform 200. The locking device 400 includes a mounting seat 410, a locking member 420, a pressure receiving member 430, and an elastic member 440. The mounting seat 410 is fixedly arranged on the rotating platform 200, for example, the mounting seat 410 can be fixedly connected to the bottom plate 201 of the rotating platform 200 by bolts. The locking member 420 is movably connected to the mounting seat 410, and is used to lock or unlock the rolling shutter door 500. The pressure receiving member 430 is connected to the locking member 420, and is used to drive the locking member 420 to move relative to the mounting seat 410 under the pressing of the pressing portion 110. The elastic member 440 is used to provide the locking member 420 with an elastic force in the direction of locking the rolling shutter door 500.

[0089] When the interface 210 is not rotated to align with the channel 100, the locking member 420 of the locking device 400 corresponding to the interface 210 is not compressed by the compression part 110, and thus the roller shutter door 500 is locked. At this time, the roller shutter door 500 corresponding to the interface 210 cannot be opened. When the interface 210 rotates towards the channel 100 along with the rotating platform 200, the pressure member 430 is compressed by the compression part 110, and the pressure member 430 drives the locking member 420 to overcome the elastic force of the elastic member 440 and move relative to the mounting base 410 until the locking member 420 unlocks the roller shutter door 500.

[0090] Therefore, in this embodiment of the invention, the rotating platform 200 drives the locking device 400 to rotate toward the channel 100. When the interface 210 rotates to align with the channel 100, the pressure member 430 of the locking device 400 corresponding to the interface 210 is simultaneously pressed by the pressing part 110, thus the roller shutter door 500 corresponding to the interface 210 is in an unlocked state. Therefore, through the cooperation of the locking device 400, the roller shutter door 500, and the channel 100, the mechanical automatic locking and unlocking of the roller shutter door 500 is achieved.

[0091] like Figure 9 and Figure 11 As shown, Figure 11 The diagram shows a partial view of the locking device 400 mounted on the rotating platform 200. The roller shutter door 500 has door frames 520 on both sides, and a clearance hole 521 is provided at the bottom of the door frame 520. The roller shutter door 500 also has a notch 510, which can be located at the end of the lowest roller shutter slat. When the roller shutter door 500 is pulled down to its final position, the notch 510 corresponds to the clearance hole 521. The locking member 420 is hinged to the mounting base 410, and one end of the locking member 420 has a hook 421 for extending into the notch 510. When the pressure member 430 is pressed by the pressing part 110, it can cause the locking member 420 to swing around the hinge point.

[0092] Specifically, when the pressure-receiving member 430 of the locking device 400 is not compressed by the pressing part 110 of the channel 100, under the action of the elastic member 440, the hook part 421 of the locking member 420 extends into the notch 510 through the relief hole 521 (e.g., Figure 15 and Figure 16 This locks the roller shutter door 500. At this time, the roller shutter door 500 cannot be opened.

[0093] When the pressure member 430 of the locking device 400 is pressed by the compression part 110, the pressure member 430 drives the locking member 420 to overcome the elastic force of the elastic member 440 and swing relative to the mounting base 410 until the hook part 421 of the locking member 420 moves out of the notch 510 (e.g. Figure 13 andFigure 14 )。

[0094] In the embodiment, the elastic member 440 is a torsion spring, and the elastic member 440 is connected to the mounting base 410 and the locking member 420. Of course, in other embodiments, the elastic member 440 can also be a compression spring, a tension spring, etc.

[0095] As shown in FIG. 4, the bottom plate 201 of the rotating platform 200 is provided with a through hole 204 penetrating the upper surface and the lower surface of the bottom plate 201. The locking member 420 is arranged in the through hole 204. Part of the locking member 420 is located on the upper surface side of the bottom plate 201, and part of the locking member 420 is located on the lower surface side of the bottom plate 201. Figure 11 As shown in FIG. 5, the pressure receiving member 430 includes a connecting portion 431 and a roller 432 rotatably connected to the connecting portion 431. The roller 432 is used to rollingly contact the extrusion portion 110, and is driven by the connecting portion 431 to move the locking member 420 in the direction of unlocking the rolling slats door 500 under the extrusion of the extrusion portion 110. Through the arrangement of the roller 432, when the rotating platform 200 is turned from the parking position to the docking position, the rolling friction between the locking device 400 and the extrusion portion 110 of the passage 100 is realized by the rolling of the roller 432 and the extrusion portion 110, so that the rotation of the rotating platform 200 is more smooth, and the friction between the locking device 400 and the extrusion portion 110 is avoided.

[0096] Figure 9 As shown in FIG. 6, the extrusion portion 110 is arranged at the bottom of one end of the passage 100, and has an arc surface 111. The curvature of the arc surface 111 is matched with the curvature of the outer wall of the rotating platform 200.

[0097] As shown in FIG. 6, the extrusion portion 110 is arranged at the bottom of one end of the passage 100, and has an arc surface 111. The curvature of the arc surface 111 is matched with the curvature of the outer wall of the rotating platform 200. Figure 10 In the embodiment, the extrusion portion 110 is an arc-shaped strip structure. When one of the docking interfaces 210 is rotated to be docked with the passage 100, the arc-shaped extrusion portion 110 can continuously extrude the pressure receiving member 430 corresponding to the docking interface 210, so that the locking member 420 is always in the state of unlocking the rolling slats door 500.

[0098] As shown in FIG. 7, the locking device 400 further includes an adjusting member 600. The adjusting member 600 is adjustably connected to the part of the locking member 420 exposed on the upper surface of the bottom plate 201. One end of the adjusting member 600 is used to abut against the door frame 520 of the rolling slats door 500. By controlling the length of the adjusting member 600 extending out of the locking member 420, the depth of the hook portion 421 extending into the avoiding hole 521 can be adjusted.

[0099] Figure 11 As an example, the adjusting member 600 is a bolt, and the bolt is screwed with the locking member 420.

[0100] As an example, the adjusting member 600 is a bolt, and the bolt is screwed with the locking member 420.

[0101] ​​The connecting device further comprises a detection unit 700 configured to detect the position of the roller shutter door 500 and feed back a position signal. When the detection unit 700 triggers the position signal, it proves that the roller shutter door 500 has been closed, ensuring safety.

[0102] As shown in Figure 12 , Figure 12 The housing 800 is shown in a partial view of the partial locking member 420. The connecting device further comprises a housing 800 covering the part of the locking member 420 exposed on the upper surface of the base plate 201, the adjusting member 600 and the escape hole 521, to avoid passengers accidentally touching the locking member 420.

[0103] Of course, it can be understood that in other embodiments, in addition to rotation, the locking member 420 can also slide linearly relative to the mounting seat 410.

[0104] Specifically, the locking member 420 is slidably arranged on the mounting seat 410, and the elastic member 440 can be arranged between the locking member 420 and the mounting seat 410, configured to provide the locking member 420 with a movement in the direction of locking the roller shutter door 500. The pressure receiving member 430 is connected with the locking member 420, and when the pressure receiving member 430 is extruded by the extrusion part 110 of the passage 100, the pressure receiving member 430 drives the locking member 420 to move in the direction of unlocking the roller shutter door 500. When the pressure receiving member 430 is not extruded by the extrusion part 110, the locking member 420 locks the roller shutter door 500 under the action of the elastic member 440.

[0105] In summary, the connecting device of the embodiment has the following advantages and beneficial effects:

[0106] Compared with the structure of the side wall roller shutter door 500 in the prior art, the roller shutter door 500 used in the connecting device of the embodiment is designed to open or shrink along the vertical direction D, which is simpler in structure, more convenient to install and lower in cost.

[0107] The connecting device of the embodiment drives the locking device 400 to rotate towards the passage 100 through the rotating platform 200, and when the docking port 210 is rotated to be docked with the passage 100, the pressure receiving member 430 of the locking device 400 corresponding to the docking port 210 is extruded by the extrusion part 110, so that the roller shutter door 500 corresponding to the docking port 210 is in an unlocked state. Therefore, through the cooperation of the locking device 400, the roller shutter door 500 and the passage 100, mechanical automatic locking and unlocking of the roller shutter door 500 are realized.
