[0029] See Figures 1 to 5 As shown, this embodiment provides a canopy device, including a front frame 1, a canopy opening and closing mechanism, and a canopy emergency retraction assembly. The front frame 1 is used to be hinged to the floor 51 of the boarding bridge. The canopy opening and closing mechanism is connected to the front frame 1 to enable the front frame 1 to rotate relative to the floor 51 of the boarding bridge. The canopy emergency retraction assembly includes a flexible connecting member 31 and a driving member 32. One end of the flexible connecting member 31 is connected to the driving member 32, and the other end of the flexible connecting member 31 is connected to the front frame 1. The driving member 32 is configured to drive the front frame 1 to rotate relative to the floor 51 of the boarding bridge through the flexible connecting member 31, so as to retract the front frame 1.

[0030] For the canopy device provided in this embodiment, when the canopy opening and closing mechanism works normally, the canopy opening and closing mechanism can drive the front frame 1 to rotate relative to the floor 51 of the boarding bridge to realize the extension and retraction of the front frame 1. When the canopy opening and closing mechanism cannot drive the front frame 1 to retract, the driving member 32 drives the front frame 1 to rotate relative to the floor 51 of the boarding bridge through the flexible connecting member 31 to drive the front frame 1 to retract, so as not to affect the normal takeoff of the aircraft. If the boarding bridge can still be withdrawn, the upper retracted part of the front frame 1 is separated from the aircraft fuselage through the canopy emergency retraction assembly, and the aircraft leaves the apron after the boarding bridge is withdrawn. If the boarding bridge cannot be withdrawn, the upper end of the front frame 1 is retracted and separated from the aircraft fuselage (the retraction amount is greater than the case where the bridge can be withdrawn) through the canopy emergency retraction assembly, and then the aircraft leaves the apron.

[0031] The boarding bridge includes a walking passage and a gantry frame 52 provided at the front end of the walking passage. The walking passage includes a floor 51. The front frame 1 is hinged to the floor 51 through a first hinge shaft 61.

[0032] In this embodiment, the canopy device further includes a tarpaulin 27, and the tarpaulin 27 is installed between the gantry frame 52 and the front frame 1.

[0033] In some embodiments, the driving member 32 is used to be installed on the gantry frame 52 of the boarding bridge. The driving member 32 can be a winch, such as a winch with a ratchet structure. The driving member 32 can be manual or electric. The driving member 32 is preferably installed at a height convenient for the operator to stand directly and operate.

[0034] In some embodiments, the flexible connecting member 31 can be a rope or a strap. Exemplarily, the material of the rope can be, but is not limited to, metal or nylon.

[0035] In some embodiments, see Figures 1 to 5 As shown, the canopy device further includes a traction wheel 33. The traction wheel 33 is used to be installed on the boarding bridge, and the part between the two ends of the flexible connecting member 31 bypasses the traction wheel 33.

[0036] Exemplarily, the traction wheel 33 is mounted on the gantry frame 52 of the boarding bridge through a mounting seat. An annular groove is provided on the circumferential surface of the traction wheel 33, and the flexible connecting member 31 can be limited in the annular groove. During the movement of the flexible connecting member 31 relative to the traction wheel 33, the flexible connecting member 31 is not easily disengaged from the annular groove.

[0037] In some embodiments, referring to Figure 1 As shown, the awning opening and closing mechanism includes a front arm 21 connected to the front frame 1, and the other end of the flexible connecting member 31 is connected to a portion of the front arm 21 close to the front frame 1. That is to say, the other end of the flexible connecting member 31 can be connected to the front frame 1 or to the front arm 21, that is, the other end of the flexible connecting member 31 is connected to the front frame 1 through the front arm 21. When the flexible connecting member 31 is connected to the front arm 21, the other end of the flexible connecting member 31 is connected to a portion of the front arm 21 close to the front frame 1.

[0038] The front arm 21 includes an upper arm portion 211, a lower arm portion 213 that are integrally formed or fixedly connected together, and a connecting portion 212 connecting the upper arm portion 211 and the lower arm portion 213. The upper arm portion 211 and the lower arm portion 213 are formed by extending from both ends of the connecting portion 212 in opposite directions.

[0039] In this embodiment, the awning opening and closing mechanism further includes a power mechanism, a rear arm 23, a swing arm 22, a first gas spring 25, and a second gas spring 26. The power mechanism can drive the front arm 21 to move so that the front frame 1 rotates relative to the floor of the boarding bridge; one end of the rear arm 23 is used for hinging with the boarding bridge, the other end of the rear arm 23 is hinged to the front arm 21, the thruster 24 is hinged to the rear arm 23, and the traction wheel 33 can be located between the hinge axis between the rear arm 23 and the boarding bridge and the driving member 32, or the traction wheel 33 can be located at the upper part of the rear arm 23 close to the hinge axis or arranged side by side with the hinge axis. Specifically, one end of the rear arm 23 is hinged to the gantry frame 52 through a second hinge axis 62, and the other end of the rear arm 23 is hinged to a position of the connecting portion 212 close to the lower arm portion 213 through a third hinge axis 63.

[0040] In some embodiments, the power mechanism can be the thruster 24.

[0041] In other embodiments, the power mechanism can also be a traction device with a belt or a steel wire rope.

[0042] One end of the swing arm 22 is rotatably connected to the lower end of the rear arm 23 through a third hinge shaft 63. The thruster 24 can be a cylinder or an oil cylinder. One end of the thruster 24 is hinged to the rear arm 23, and the other end of the thruster 24 is hinged to the other end of the swing arm 22. Both ends of the first gas spring 25 are respectively hinged to appropriate positions of the front arm 21 and the rear arm 23. One end of the second gas spring 26 is hinged to the gantry frame 52, and the other end of the second gas spring 26 is hinged to an appropriate position of the rear arm 23. The second gas spring 26 is located on one side of the rear arm 23 close to the gantry frame 52.

[0043] See Figure 1 and Figure 2 As shown, when the awning opening and closing mechanism is converted from the fully retracted state to the fully deployed state, the thruster 24 begins to shorten. The thruster 24 drives the swing arm 22 to rotate around the third hinge shaft 63 in a set direction (for example, clockwise), and a gap is generated between the swing arm 22 and the lower arm portion 213. Since the first gas spring 25 is in a compressed state and has a strong tendency to extend, at this time, since the front arm 21 is not affected by other external forces, the front arm 21 begins to rotate around the third hinge shaft 63 in the set direction under the action of the first gas spring 25 until the lower arm portion 213 is in close contact with the swing arm 22. At the same time, since the front frame 1 is hinged to the front arm 21, the front frame 1 also begins to rotate around the first hinge shaft 61 in the set direction under the drive of the front arm 21. At the same time, since the second gas spring 26 is also in a compressed state and has a strong tendency to extend, the rear arm 23 rotates around the second hinge shaft 62 in the set direction under the thrust of the second gas spring 26. When the thruster 24 is retracted to the shortest state, the first gas spring 25 can be in the fully extended state. The first gas spring 25 pushes the lower arm portion 213 of the front arm 21 to be in close contact with the swing arm 22, and the front frame 1 also rotates to the farthest position around the first hinge shaft 61 under the drive of the front arm 21. When the awning is in the fully extended state, the front arm 21 transmits the thrust of the first gas spring 25 acting on the front arm 21 to the front frame 1, so that there is a good seal between the front frame 1 and the aircraft. At the same time, the second gas spring 26 can also be in the fully extended state, and the rear arm 23 can also be in the highest position under the action of the second gas spring 26.

[0044] It should be understood that the movement process of the awning opening and closing mechanism from the fully deployed state to the fully retracted state should be understandable to those skilled in the art, and is well-known and easy to implement for those skilled in the art. Therefore, this embodiment will not be described in detail.

[0045] In some embodiments, the other end of the flexible connector 31 is indirectly connected to the front frame 1 through the front arm 21 of the awning opening and closing mechanism. Exemplarily, see Figure 1 As shown, a hanging ring 2111 is provided on the upper arm portion 211, and the other end of the flexible connector 31 is connected to the hanging ring 2111.

[0046] In other embodiments, the other end of the flexible connecting member 31 may also be directly connected to the front frame 1.

[0047] In some embodiments, the awning device further includes an adsorbing member; the flexible connecting member 31 is detachably adsorbed on the surface of the awning opening and closing mechanism through the adsorbing member. This can ensure that the flexible connecting member 31 does not affect the normal operation of the awning opening and closing mechanism.

[0048] Exemplarily, referring to Figure 1 and Figure 2 as shown, the flexible connecting member 31 can be adsorbed on the surfaces of the front arm 21 and the rear arm 23. At the hinge joint of the front arm 21 and the rear arm 23, the flexible connecting member 31 can have a surplus. When the awning opening and closing mechanism drives the front frame 1 to swing outwards, the flexible connecting member 31 can move together with the front arm 21 and the rear arm 23. When the angle between the front arm 21 and the rear arm 23 gradually increases, the flexible connecting member 31 does not restrict the movement of the front arm 21 and the rear arm 23. Of course, the flexible connecting member 31 also does not affect the awning opening and closing mechanism to drive the front frame 1 to retract in the normal working state.

[0049] Exemplarily, the adsorbing member includes a magnetic member, a buckle or a magic tape.

[0050] In some embodiments, the awning device further includes an energy storage member; one end of the flexible connecting member 31 is detachably connected to the driving member 32. One end of the flexible connecting member 31 can be separated from the driving member 32 and connected to the energy storage member. The energy storage member is configured to store energy when the awning opening and closing mechanism drives the front frame 1 to rotate away from the boarding bridge, and the energy storage member is further configured to release energy when the awning opening and closing mechanism drives the front frame 1 to rotate towards the boarding bridge, so as to retract the flexible connecting member 31.

[0051] By providing the energy storage member, it can also ensure that the flexible connecting member 31 does not affect the normal operation of the awning opening and closing mechanism.

[0052] Exemplarily, the energy storage member includes a counterweight 4a. Referring to Figure 3 and Figure 4 as shown, when the awning opening and closing mechanism is working normally, the flexible connecting member 31 is separated from the driving member 32, and then the flexible connecting member 31 is connected to the counterweight 4a. When the awning opening and closing mechanism drives the front frame 1 to rotate away from the boarding bridge, even when the awning device moves to the unfolded state, the counterweight 4a rises to store energy. When the awning opening and closing mechanism drives the front frame 1 to rotate towards the boarding bridge, even when the awning device moves to the retracted state, the counterweight 4a descends, driving the end of the flexible connecting member 31 to move downward, so that the flexible connecting member 31 is basically in a taut state and retracts as the front frame 1 retracts, without affecting the normal operation of the awning opening and closing mechanism.

[0053] Of course, the energy storage member may also include an elastic member. For example, a gas spring, a coil spring, a torsion spring, a tension spring or a compression spring.

[0054] Exemplarily, referring to Figure 5 As shown, when the energy storage member is a coil spring 4b, the coil spring can be installed in a driving member (such as a winch). The elastic force of the coil spring can pull back and straighten the flexible connecting member, but generally does not pull the front arm and the front frame. During the process of the awning device switching from the deployed state to the retracted state, the coil spring can wind the flexible connecting member around the shaft of the winch, achieving a state substantially the same as the taut state of the Figure 4 flexible connecting member shown.

[0055] It should be noted that the structure of the awning opening and closing mechanism is not limited to the above one, as long as it can realize the functions of deploying and retracting the awning.

[0056] This embodiment also provides a boarding bridge, including the awning device provided in this embodiment.

[0057] For the boarding bridge provided in this embodiment, since the awning device provided in this embodiment is used, when the awning opening and closing mechanism works normally, the awning opening and closing mechanism can drive the front frame 1 to rotate relative to the floor 51 of the boarding bridge, realizing the extension and retraction of the front frame 1. When the awning opening and closing mechanism cannot drive the front frame 1 to retract, the driving member 32 drives the front frame 1 to rotate relative to the floor 51 of the boarding bridge through the flexible connecting member 31, so as to drive the front frame 1 to retract, thus not affecting the normal takeoff of the aircraft.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
