[0100] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings. Example embodiments, may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and descriptions of the same or similar elements can be not be repeated.

[0101] The embodiments of the present application provide a docking device, which can be a boarding bridge, a boarding ladder, a boarding vehicle, a food vehicle, etc. for docking with an airplane, or a boarding bridge, etc. for docking with a ship.

[0102] As shown in Figure 1 and Figure 2 , the docking device includes a docking port 100, a guardrail assembly 200, and a walkway assembly 400. The guardrail assembly 200 is movably connected to the docking port 100, and the walkway assembly 400 is rotatably connected to the docking port 100. The guardrail assembly 200 and the walkway assembly 400 are linked.

[0103] It is to be understood that the terms "including", "comprising", "having" and variations thereof herein are intended to be broad and encompass the terms "consisting of" and "consisting essentially of". For example, a process, method, system, product, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but can include other steps or elements not expressly listed or inherent to such process, method, system, product, or apparatus.

[0104] The connection device of the embodiment of the present application, the transition plate assembly 400 is linked with the guardrail assembly 200, when the operator operates the guardrail assembly 200, the transition plate assembly 400 can also be linked therewith. On the one hand, the guardrail assembly 200 and the transition plate assembly 400 can be driven to move simultaneously through one operation, which improves the convenience of operation; on the other hand, since the guardrail assembly 200 and the transition plate assembly 400 are linked, the situation that the operator only drives the guardrail assembly 200 to reset and forgets to operate the transition plate assembly 400 to reset will not occur, which effectively improves the safety.

[0105] The connection device can further include a passage (not shown in the figure), and the connection port 100 is arranged at one end of the passage.

[0106] As shown in Figure 1 and Figure 2 , the connection port 100 is provided with a connection passage 110 for passengers to pass through, and the connection passage 110 is in communication with the passage. The connection port 100 includes a bottom plate 130, a top plate 140 and two side frames 150. The bottom plate 130 and the top plate 140 are arranged opposite to each other along the up-down direction D1 (wherein the direction indicated by the arrow is upward, and the reverse direction is downward), and the two side frames 150 are arranged opposite to each other along the left-right direction D2 (wherein the direction indicated by the arrow is left, and the reverse direction is right). Each side frame 150 is provided with two opposite side edges in the up-down direction D1, and the two side edges are connected with the bottom plate 130 and the top plate 140 respectively.

[0107] The bottom plate 130, the top plate 140 and the two side frames 150 jointly enclose the connection passage 110, and the connection passage 110 has two opposite openings in the front-rear direction D3 (wherein the direction indicated by the arrow is forward, and the reverse direction is rearward), and the passengers pass through the connection passage 110 along the front-rear direction D3.

[0108] Please continue to refer to Figure 1 and Figure 2 , the connection device of the embodiment of the present application includes two guardrail assemblies 200 and two transition plate assemblies 400. The two guardrail assemblies 200 are movably connected to the inner side surfaces of the two side frames 150 respectively, and the two guardrail assemblies 200 are arranged opposite to each other along the left-right direction D2. The two transition plate assemblies 400 are rotatably connected to the bottom plate 130, and the two transition plate assemblies 400 are butted along the left-right direction D2. One of the guardrail assemblies 200 is linked with one of the transition plate assemblies 400, and the other guardrail assembly 200 is linked with the other transition plate assembly 400.

[0109] Of course, in another embodiment, the connecting device may include two guardrail assemblies 200 and a ramp assembly 400. The two guardrail assemblies 200 are also movably connected to the inner sides of the two side frames 150, and are arranged opposite each other in the left-right direction D2. The ramp assembly 400 is rotatably connected to the base plate 130, and the ramp assembly 400 is simultaneously linked with the two guardrail assemblies 200. The two guardrail assemblies 200 can be connected by a synchronization mechanism to enable synchronized movement.

[0110] In another embodiment, the connecting device may include a guardrail assembly 200 and a ramp assembly 400, wherein the connection relationship between the guardrail assembly 200 and the ramp assembly 400 can be referred to the above embodiment, and will not be repeated here.

[0111] The rotatable connection between the ramp assembly 400 and the docking port 100 can be achieved via a hinge, but is not limited to this. The ramp assembly 400 is positioned relative to the docking port 100 in an open position P21 and a retracted position P22. The ramp assembly 400 is capable of rotating between the open position P21 and the retracted position P22.

[0112] When the guardrail assembly 200 is movably connected to the connecting port 100 along a straight line, the guardrail assembly 200 is retractably connected to the connecting port 100 along the passenger passage direction (i.e., the front-to-back direction D3), and the position of the guardrail assembly 200 relative to the connecting passage 110 includes an extended position P11 and a retracted position P12. When the guardrail assembly 200 is in the extended position P11, at least a portion of the guardrail assembly 200 extends out of the connecting passage 110, while the ramp assembly 400 is in the open position P21. When the guardrail assembly 200 is in the retracted position P12, part or all of the guardrail assembly 200 retracts into the connecting passage 110, while the ramp assembly 400 is in the folded position P22. It is worth noting that the term "position" in this application should be broadly understood as relative position.

[0113] like Figure 3 As shown, the guardrail assembly 200 includes a guardrail body 210, a first linkage 220, and a second linkage 230. The guardrail body 210 is retractably connected to the connection port 100. The first linkage 220 is located on the guardrail body 210 and is used to rotate the ramp assembly 400 from the retracted position P22 to the open position P21 when the guardrail assembly 200 moves from the retracted position P12 to the extended position P11. The second linkage 230 is located on the guardrail body 210 and is used to rotate the ramp assembly 400 from the open position P21 to the retracted position P22 when the guardrail assembly 200 moves from the extended position P11 to the retracted position P12.

[0114] It can be understood that the guardrail body 210 and the docking port 100 can be connected through the sliding structure 300.

[0115] As Figures 3 to 5 In an embodiment, the sliding structure 300 includes a guide groove 310 and a guide wheel 320, the guide groove 310 is arranged on one of the guardrail body 210 and the docking port 100, and the guide wheel 320 is arranged on the other one of the guardrail body 210 and the docking port 100, and the guide wheel 320 is rollably arranged in the guide groove 310.

[0116] In the embodiment, the guide groove 310 is fixedly installed on the guardrail body 210. The guide wheel 320 is installed on the side frame 150 of the docking port 100 through a mounting seat 330. The guide wheel 320 is rotatably connected to the mounting seat 330.

[0117] As Figure 5 Further, as shown, a plurality of guide wheels 320 are arranged on the mounting seat 330, the rotation axes of some of the guide wheels 320 are parallel to the left-right direction D2, and the rotation axes of some of the guide wheels 320 are parallel to the up-down direction D1. In this way, the plurality of guide wheels 320 can not only guide the extension and retraction of the guardrail assembly 200, but also limit the shaking of the guardrail assembly 200 relative to the docking port 100.

[0118] Of course, the sliding structure 300 is not limited to the guide groove 310 and the guide wheel 320, as long as the guardrail assembly 200 can be telescopically connected to the docking port 100, which will not be listed one by one here.

[0119] As Figure 6 and Figure 7 The bridge plate assembly 400 includes a bridge plate 410, a first pressure receiving member 420, and a second pressure receiving member 430. The bridge plate 410 is rotatably connected to the docking port 100, for example, through a hinge. The first pressure receiving member 420 is arranged on the bridge plate 410 and used to abut against the first linkage 220 when the guardrail assembly 200 moves from the retracted position P12 to the extended position P11. The second pressure receiving member 430 is arranged on the bridge plate 410 and used to abut against the second linkage 230 when the guardrail assembly 200 moves from the extended position P11 to the retracted position P12.

[0120] Specifically, when the guardrail assembly 200 moves from the retracted position P12 to the extended position P11, the first linkage 220 pushes against the first pressure receiving member 420, thereby driving the bridge plate assembly 400 to rotate from the stowed position P22 to the open position P21. When the guardrail assembly 200 moves from the extended position P11 to the retracted position P12, the second linkage 230 pushes against the second pressure receiving member 430, thereby driving the bridge plate assembly 400 to rotate from the open position P21 to the stowed position P22.

[0121] As Figure 6 andFigure 7 As shown, the ramp 410 includes a ramp body 411, a connector 412, and a swing arm 413. The connector 412 is fixedly connected to the ramp body 411, and the swing arm 413 is connected to one end of the connector 412. A first pressure-bearing member 420 and a second pressure-bearing member 430 are provided on the swing arm 413.

[0122] like Figure 7 As shown, the ramp 410 further includes a first mounting arm 413a and a second mounting arm 413b. A first pressure-bearing member 420 is connected to a swing arm 413 via the first mounting arm 413a, and a second pressure-bearing member 430 is connected to the swing arm 413 via the second mounting arm 413b. The first mounting arm 413a and the second mounting arm 413b are angled together. Preferably, the angle between the first mounting arm 413a and the second mounting arm 413b is between 45 degrees and 90 degrees, for example, 45 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, and 90 degrees.

[0123] Both the first pressure-bearing member 420 and the second pressure-bearing member 430 include rollers, which are rotatably mounted on the swing arm 413 of the ramp 410. By designing the first pressure-bearing member 420 and the second pressure-bearing member 430 as rollers, rolling contact can be achieved between the first linkage member 220 and the first pressure-bearing member 420, and between the second linkage member 230 and the second pressure-bearing member 430, thereby reducing linkage resistance.

[0124] like Figure 8 As shown, when the guardrail assembly 200 is in the extended position P11, the first linkage 220 is positioned on the path of the ramp assembly 400 moving from the open position P21 to the retracted position P22, to prevent the ramp assembly 400 from rotating from the open position P21 to the retracted position P22. Thus, the first linkage 220 acts as a stop, ensuring that when the guardrail assembly 200 is in the extended position P11, the ramp assembly 400 cannot rotate from the open position P21 to the retracted position P22. Specifically, the first linkage 220 engages with the first pressure-bearing member 420 to limit rotation, preventing the ramp assembly 400 from rotating from the open position P21 to the retracted position P22.

[0125] When the guardrail assembly 200 is in the retracted position P12, the second linkage 230 is positioned on the path of the ramp assembly 400 as it moves from the retracted position P22 to the open position P21, preventing the ramp assembly 400 from rotating from the retracted position P22 to the open position P21. Thus, the second linkage 230 acts as a stop, ensuring that when the guardrail assembly 200 is in the retracted position P12, the ramp assembly 400 cannot rotate from the retracted position P22 to the open position P21. Specifically, the second linkage 230 engages with the second pressure-bearing member 430 to limit rotation, preventing the ramp assembly 400 from rotating from the retracted position P22 to the open position P21.

[0126] likeFigure 8 As shown, the docking device further comprises a detection element 800 and a controller (not shown). The detection element 800 is configured to detect whether the guardrail assembly 200 is in the retracted position P12. The controller is communicatively connected with the detection element 800. When the guardrail assembly 200 is moved from the extended position P11 to the retracted position P12, the detection element 800 is triggered and sends a signal indicating that the guardrail assembly 200 is in the retracted position P12. The controller controls the movement of the docking device according to the signal indicating that the guardrail assembly 200 is in the retracted position P12. Conversely, if the detection element 800 does not send the signal indicating that the guardrail assembly 200 is in the retracted position P12, it means that the guardrail assembly 200 is not retracted, and the docking device cannot be moved.

[0127] The docking device further comprises a buffer assembly 900 connected to the docking port 100 and the apron assembly 400, which is configured to slow down the movement of the apron assembly 400 from the stowed position P22 to the open position P21.

[0128] In an embodiment, the buffer assembly 900 comprises a gas spring 910 and a tension spring 920. One end of the gas spring 910 is connected to the side frame 150 of the docking port 100, and the other end is connected to the swing arm 413 of the apron assembly 400. One end of the tension spring 920 is connected to the side frame 150 of the docking port 100, and the other end is connected to the swing arm 413 of the apron assembly 400.

[0129] Of course, the buffer assembly 900 is not limited to the gas spring 910 and the tension spring 920, and other components that can function as a buffer can also be used, which will not be listed one by one here.

[0130] As shown in FIGS. Figure 5 , Figure 9 and Figure 10 The docking device further comprises a locking assembly 600 configured to lock the guardrail assembly 200. By providing the locking assembly 600, the guardrail assembly 200 can be locked in the extended position P11, the retracted position P12, and an intermediate position between the extended position P11 and the retracted position P12.

[0131] The locking assembly 600 comprises a locking member 610, an operating member 620, and a resilient member 630. The position of the locking member 610 relative to the guardrail assembly 200 comprises a locked position and an unlocked position. In the locked position, the locking member 610 locks the guardrail assembly 200. In the unlocked position, the guardrail assembly 200 is movable relative to the docking port 100. The operating member 620 is connected to the locking member 610 and is configured to move the locking member 610 to the unlocked position when subjected to an external force. The resilient member 630 is configured to provide the locking member 610 with an elastic force to move to the locked position.

[0132] As shown in FIGS. Figure 5As shown, the adapter 100 is provided with a hole plate 120, and the hole plate 120 is provided with a plurality of insertion holes 121 arranged along the front-rear direction D3. In the locked position, the locking member 610 is inserted into any one of the insertion holes 121. In the unlocked position, the locking member 610 is removed from the insertion hole 121. The arrangement of the plurality of insertion holes 121 not only allows the amount and position of the outward extension of the guardrail assembly 200 to be adaptively selected according to actual conditions, but also allows the locking member 610 to be automatically inserted into the insertion hole 121 and locked even if the locking member 610 is not timely inserted into the insertion hole 121 and locked after the guardrail assembly 200 is moved forward or backward, and the elastic force of the elastic member 630 drives the locking member 610 to be automatically inserted into the insertion hole 121 and locked, thereby improving safety and reliability.

[0133] As shown in Figure 9 and Figure 10 The operating member 620 includes a first operating member 621 and a second operating member 622. The first operating member 621 is rotatably connected to the guardrail body 210 of the guardrail assembly 200, the second operating member 622 is rotatably connected to the guardrail body 210 of the guardrail assembly 200, and the second operating member 622 is hinged to the first operating member 621. One of the first operating member 621 and the second operating member 622 is hinged to the locking member 610. One end of the elastic member 630 is connected to the guardrail body 210 of the guardrail assembly 200, and the other end of the elastic member 630 is connected to one of the first operating member 621 and the second operating member 622. When the operator operates any one of the first operating member 621 and the second operating member 622, the locking member 610 can be moved.

[0134] In the embodiment, the locking member 610 is hinged to the second operating member 622, and the other end of the elastic member 630 is connected to the first operating member 621.

[0135] The first operating member 621 and the second operating member 622 each include a handle portion 623, and the two handle portions 623 are oppositely arranged along the front-rear direction D3. In this way, the operator can operate the handle portion 623 of the first operating member 621 inside the adapter 100, and can also operate the handle portion 623 of the second operating member 622 outside the adapter 100, such as on a floor access passage.

[0136] Of course, in another embodiment, the operating member 620 can include one of the first operating member 621 and the second operating member 622, the operating member is hinged to the guardrail body 210 and is hinged to the locking member 610.

[0137] In yet another embodiment, the operating member 620 can include the first operating member 621 and the second operating member 622, the first operating member 621 and the second operating member 622 are each hinged to the guardrail body 210 and are each hinged to the locking member 610, and the first operating member 621 and the second operating member 622 are not hinged to each other.

[0138] The locking assembly 600 further comprises a guide 640 provided on the guardrail body 210 of the guardrail assembly 200 for guiding the locking member 610 to move between the locked position and the unlocked position.

[0139] In an embodiment, the guide 640 can comprise a sleeve, and the locking member 610 is movably arranged in the sleeve.

[0140] In other embodiments, the locking assembly 600 can also be other different implementations, for example, a bolt and a plurality of pin holes are matched, the bolt is inserted into the pin hole to achieve locking, and the bolt is pulled out of the pin hole to achieve unlocking, in addition, the bolt can be manually operated or automatically controlled by electric driving; a screw and a plurality of nuts are matched; a magnetic attraction type is matched; a magic tape type is matched, and the like.

[0141] In the embodiment, the manual operation of the locking assembly 600 and the manual pushing of the guardrail assembly 200 are taken as an example. In other embodiments, the automatic driving device can be additionally installed to drive the guardrail assembly 200 to move, and the corresponding locking assembly can also adopt an automatic device.

[0142] When the docking device is docked with the pier or the waiting corridor, the operator pulls the first operating member 621 or the second operating member 622 of the operating member 620, and then drives the locking member 610 to move out of the insertion hole 121, so that the guardrail assembly 200 is in a movable state. Then, the operator operates the guardrail assembly 200 to move from the retracted position P12 to the extended position P11. Since the guardrail assembly 200 is linked with the apron assembly 400, when the guardrail assembly 200 moves from the retracted position P12 to the extended position P11, the first linkage member 220 of the guardrail assembly 200 pushes the first pressure receiving member 420 of the apron assembly 400, so that the apron assembly 400 rotates from the stowed position P22 to the open position P21. During the movement of the apron assembly 400 from the stowed position P22 to the open position P21, the gas spring 910 and the tension spring 920 of the buffer assembly 900 can slow down the rotation speed of the apron assembly 400. The guardrail assembly 200 moves to the extended position P11, the locking member 610 is inserted into one of the plurality of insertion holes 121 to lock the guardrail assembly 200 at the extended position P11. At the same time, the first linkage member 220 of the guardrail assembly 200 stops the first pressure receiving member 420 of the apron assembly 400, preventing the apron assembly 400 from rotating from the open position P21 to the stowed position P22.

[0143] When retracting the guardrail assembly 200, the operator first pulls the first operating member 621 or the second operating member 622 of the operating member 620 to drive the locking member 610 out of the insertion hole 121, and then moves the guardrail assembly 200 from the extended position P11 to the retracted position P12. During the movement of the guardrail assembly 200, the second linkage 230 of the guardrail assembly 200 pushes the second pressure-receiving member 430 of the transition plate assembly 400, so that the transition plate assembly 400 rotates from the open position P21 to the stowed position P22. When the guardrail assembly 200 moves to the retracted position P12, the locking member 610 is inserted into one of the insertion holes 121 to lock the guardrail assembly 200 at the retracted position P12. At the same time, the second linkage 230 of the guardrail assembly 200 stops the second pressure-receiving member 430 of the transition plate assembly 400, preventing the transition plate assembly 400 from rotating from the stowed position P22 to the open position P21.
