The left door leaf 21 is connected and driven by the left driving assembly 101 through the left connecting assembly 201, and the right door leaf 22 is connected and driven by the right driving assembly 102 through the right connecting assembly 202, so that the left door leaf 21 and the right door leaf 22 can be controlled respectively, the control circuit is simple in design, high in control reliability and control accuracy, and low in cost.

[0057] In the embodiment, the door 2 is provided with a detection plate 24 for detecting whether the door 2 is completely closed. A left detection plate 241 is arranged at an end of the left door leaf 21 away from a door shaft, and a right detection plate 242 is arranged at an end of the right door leaf 22 away from the door shaft.

[0058] In the embodiment, referring to Figure 2The left connecting assembly 201 comprises a first left connecting piece 2011 and a second left connecting piece 2012, the first left connecting piece 2011 and the second left connecting piece 2012 are hinged, the first left connecting piece 2011 is hinged to the left driving assembly 101, and the second left connecting piece 2012 is hinged to the left door leaf 21. The first left connecting piece 2011 and the second left connecting piece 2012 are hinged to each other to realize the connection of the left driving assembly 101 and the left door leaf 21, and the structure is simple. The connecting piece can adopt the form of a connecting pipe, and the use of the connecting pipe can reduce the weight of the left connecting assembly 201, so that the load of the left driving assembly 101 is as small as possible during the driving of the opening and closing of the left door leaf 21, which is beneficial to energy saving.

[0059] In the embodiment, referring to Figure 2 The right connecting assembly 202 comprises a right connecting piece 2021 and a guide rail sliding block mechanism 2022, one end of the right connecting piece 2021 is hinged to the right driving assembly 102, the other end is hinged to a sliding block 20221, the sliding block 20221 slides in a guide rail 20222, and the guide rail 20222 is fixed to the right door leaf 22. The guide rail sliding block mechanism 2022 fixed to the right door leaf 22 can only exert a force to push the sliding block 20221 to slide along the guide rail 20222 when driving the right door leaf 22 to open and close, which is labor-saving and convenient to control; the right connecting piece 2021 is arranged between the sliding block 20221 and the right driving assembly 102, the connecting piece can adopt the form of a connecting pipe, the connecting piece is light in weight, and the right connecting piece 2021 can drive the sliding block 20221 to slide smoothly, further saving labor.

[0060] In the embodiment, the locking structure comprises a limit switch 30 and a driving brake, the limit switch 30 is arranged on a door frame 23 of the door 2 and is used for detecting whether the door 2 is completely opened or completely closed, and when the limit switch 30 detects that the door 2 is completely opened or completely closed, the limit switch 30 controls the driving brake to brake the driving structure 10 through a controller. The limit switch 30 arranged on the door frame 23 can accurately detect the opening and closing state of the door 2, the controller and the limit switch 30 are electrically connected, so that the controller can control the driving structure 10 in real time according to the information detected by the limit switch 30. For example, when the limit switch 30 detects that the door 2 has been completely opened, the limit switch 30 sends the information to the controller, and after the controller receives the information, the driving brake is started to brake the driving structure 10, so that the door 2 remains in a stable completely opened state.

[0061] In the embodiment, the limit switch 30 includes a left first switch 301, a left second switch 302, a right first switch 303 and a right second switch 304. The left first switch 301 is used to detect that the left door leaf 21 is fully opened, the right first switch 303 is used to detect that the right door leaf 22 is fully opened, the left second switch 302 is used to detect that the left door leaf 21 is fully closed, and the right second switch 304 is used to detect that the right door leaf 22 is fully closed. The limit switch 30 is provided with four switches, which can respectively detect that the left door leaf 21 and the right door leaf 22 are fully opened and fully closed, and can realize the separate control of the left door leaf 21 and the right door leaf 22 without affecting each other. In addition, the left door leaf 21 or the right door leaf 22 or both the left door leaf 21 and the right door leaf 22 can be selected to be opened according to the volume of the goods passing through the door 2.

[0062] In the embodiment, the automatic door opening and closing device 1 further includes a human body sensor 40 arranged on the door frame 23 of the door 2 and used to sense whether a person passes through the door 2 during the opening and closing of the door 2. When the human body sensor 40 senses that a person passes through the door 2, the human body sensor 40 drives the brake driving structure 10 through the controller. The arrangement of the human body sensor 40 can detect in real time whether a person passes through during the opening and closing of the door 2, can ensure that the passing person will not be collided by the door 2, can avoid the occurrence of the situation that the person is injured, and can also avoid the damage of the automatic door opening and closing device 1 caused by the collision between the person and the door 2.

[0063] Figure 3 is a schematic view of the fully opened state of the left door leaf 21 of the application. When the left door leaf 21 is fully opened, the left first switch 301 will be touched, and the left first switch 301 will send a signal of the fully opened state of the left door leaf 21 to the controller. The controller controls the brake driving structure to brake the motor 111 and lock the fully opened state of the left door leaf 21. The left door leaf 21 can stably keep the fully opened state and can resist a large wind load.

[0064] Figure 4 is a schematic view of the fully closed state of the left door leaf 21 of the application. When the left door leaf 21 is fully closed, the left detection plate 241 fixed to the left door leaf 21 will touch the left second switch 302, and the left second switch 302 will send a signal to the controller. The controller receives the signal, brakes the motor 111, and locks the fully closed state of the left door leaf 21. The left door leaf 21 can stably keep the fully closed state, can avoid that the left door leaf 21 is pushed away by an external force or blown away by a strong wind, and can avoid safety accidents caused by the external force or the strong wind.

[0065] Similarly, for the right door leaf 22, when the right door leaf 22 is fully opened, the right door leaf 22 will touch the right second switch 304, and the right second switch 304 will send a signal of the fully opened right door leaf 22 to the controller, and the controller controls the drive brake to brake the motor 111, and locks the fully opened state of the right door leaf 22. The right door leaf 22 stably maintains the fully opened state and can resist a large wind load. When the right door leaf 22 is fully closed, the right detection plate 242 fixed to the right door leaf 22 touches the right first switch 303, and the right first switch 303 sends a signal to the controller. The controller receives the signal, brakes the motor 111, and locks the fully closed state of the right door leaf 22. The locked right door leaf 22 maintains the stable fully closed state, which can avoid the right door leaf 22 being pushed open by external force or being blown open by strong wind, and can avoid safety accidents caused by external force or strong wind.

[0066] Since the drive structure 10 includes the left drive assembly 101 and the right drive assembly 102, regarding the drive structure 10 in Figures 5 to 7 , the left drive assembly 101 or the right drive assembly 102 is represented, that is, the left drive assembly 101 and the right drive assembly 102 are the same in structure, and in Figures 5 to 7 , only one of the drive assemblies in the drive structure 10 is shown, and the other drive assembly is the same as the shown drive assembly in composition and structure.

[0067] In the embodiment, referring to Figures 5 to 7 , the left drive assembly 101 and the right drive assembly 102 of the drive structure 10 each include a motor 111, a coupling 112, and a clutch hand brake 113. The coupling 112 connects the motor 111 and the connecting structure 20. The coupling 112 is composed of an upper half 1121 and a lower half 1122. The clutch hand brake 113 is used to drive the lower half 1122 to move to separate the upper half 1121 and the lower half 1122. The motor 111 drives the connecting structure 20 to move through the coupling 112. The coupling 112 is provided in the form of a half coupling separated into an upper half and a lower half. The clutch hand brake 113 is arranged between the upper half and the lower half. When an emergency occurs and manual opening of the door 2 is required by cutting off the driving of the motor 111, referring to Figure 7 , the clutch hand brake 113 can be pulled downward (in the direction of the axis of the motor 111, away from the motor 111) to separate the lower half 1122 and the upper half 1121 of the coupling 112. In this way, the motor 111 only drives the upper half 1121 of the coupling 112 to rotate, and the lower half 1122 of the coupling 112 does not rotate with the upper half 1121 of the coupling 112, so that the switching between electric driving and manual driving can be realized. When the emergency is over, referring to Figure 5 and Figure 6The clutch hand brake 113 can be pulled upward (along the axis of the motor 111, towards the direction of the motor 111) so that the upper half 1121 and the lower half 1122 of the shaft coupling 112 are connected.

[0068] The clutch hand brake 113 is mainly used for switching between electric and manual driving, avoiding the emergency risk caused by the failure of the automatic door opening and closing device 1, and improving the safety of the automatic door opening and closing device 1.

[0069] In this embodiment, the left drive assembly 101 and the right drive assembly 102 of the drive structure 10 each further includes a resilient member 114, which is arranged on the lower half 1122 of the shaft coupling 112. The elastic force of the resilient member 114 is used to drive the upper half 1121 of the shaft coupling 112 to move close to the lower half 1122. When the clutch hand brake 113 is pulled upward, the lower half 1122 of the shaft coupling 112 moves in the direction of approaching the upper half 1121 under the rebound of the elastic force of the resilient member 114, and is connected with the upper half 1121 of the shaft coupling 112. The resilient member 114 can be a compression spring or other elastic structure.

[0070] From the above, Figure 7 It can be seen that the clutch hand brake 113 includes a brake frame 1132 and a handle 1131, which are fixed and arranged between the upper half 1121 and the lower half 1122 of the shaft coupling 112. The shaft coupling 112 adopts a clamping type shaft coupling. The upper half 1121 is provided with a clamping groove, and the lower half 1122 is provided with a protrusion. The protrusion of the lower half 1122 and the clamping groove of the upper half 1121 are separated to realize the separation of the shaft coupling 112, and the protrusion is clamped in the clamping groove to realize the clamping of the shaft coupling 112. The lower half 1122 of the shaft coupling 112 has a convex edge, and the resilient member 114 is arranged below the convex edge. The resilient member 114 is extruded by the convex edge and can apply an upward thrust to the convex edge, thereby realizing the connection of the upper half 1121 and the lower half 1122 of the shaft coupling 112. The brake frame 1132 contacts the convex edge of the lower half 1122 of the shaft coupling 112. When the handle 1131 drives the brake frame 1132 to move downward, the brake frame 1132 presses the convex edge downward, the convex edge presses the resilient member 114 downward, and the lower half 1122 and the upper half 1121 of the shaft coupling 112 are separated.

[0071] The left drive assembly 101 and the right drive assembly 102 of the drive structure 10 each further include a housing. The housing is provided with a brake slot. The handle 1131 passes through the brake slot and is exposed outside the housing, and can move up and down in the brake slot. The end of the lower half 1122 of the shaft coupling 112 away from the upper half 1121 is provided with a pin shaft 110, which can be hinged to the connecting structure 20.

[0072] In this embodiment, referring to Figures 5 to 7The left drive assembly 101 and the right drive assembly 102 of the drive structure 10 each also include a rebounder 115. The rebounder 115 includes a body 1151 and a hook 1152. The body 1151 is fixedly connected to the lower half 1122 of the coupling 112, and the hook 1152 is fixedly connected to the clutch 113. When the clutch 113 separates the upper half 1121 and the lower half 1122 of the coupling 112, the hook 1152 hooks the body 1151 to prevent the clutch 113 from moving. As the clutch 113 moves downwards, separating the upper half 1121 and the lower half 1122 of the coupling 112, the elastic element 114 in the lower half 1122 of the coupling 112 is further compressed, resulting in a greater upward thrust on the lower half 1122 of the coupling 112. The lower half 1122 of the coupling 112 is fixed to the body 1151 of the rebound device 115, while the hook 1152 of the rebound device 115 is fixed to the clutch 113. Thus, when the clutch 113 moves downwards and separates the coupling 112, the hook 1152 hooks onto the body 1151 to resist the upward thrust exerted by the elastic element 114 on the clutch 113, thereby preventing the clutch 113 from moving upwards. The rebound device 115 can be an elephant trunk lock rebound device 115. When it is necessary to lift the clutch 113 upward, the operator can press the body 1151 to disengage the hook 1152 from the body 1151, and then lift the clutch 113.

Therefore, in the following description of this embodiment, the structures of the same type as those described in the previous embodiments will be mainly referred to. Figures 1 to 7 The differences between the automatic door opening and closing device 1 in the embodiments will be explained. In this third embodiment, the left drive assembly 101 and the right drive assembly 102 of the drive structure 10 each include a motor 111 and a manual release device 116. The manual release device 116 can connect or disconnect the drive brake and the motor 111. When the drive brake is connected to the motor 111, the motor 111 can rotate when the drive brake is in the released state; when the drive brake is in the braked state, the motor 111 is braked and locked. In this third embodiment, the left connecting assembly 201 also adopts the crank-slider mechanism adopted by the right connecting assembly 202 in the first embodiment.

[0075] The left connecting component 201 and the right connecting component 202 can be the same or different. They can both adopt a crank-slider mechanism, or they can both adopt a four-bar linkage mechanism similar to the left connecting component 201 in the first embodiment, or they can each adopt one of the two: a crank-slider mechanism and a four-bar linkage mechanism.

[0076] like Figures 8 to 10 As shown, this application also provides a boarding bridge 100, including a door 2 and an automatic door opening and closing device 1 disposed on the door 2 as described above.

[0077] The above is a detailed description of several exemplary embodiments of the automatic door opening and closing device 1 and boarding bridge 100 proposed in this application. The following will describe in detail the usage process of the automatic door opening and closing device 1 and boarding bridge 100 proposed in this application.

[0078] First and second implementation methods:

[0079] Combined with appendix Figures 1 to 10 The usage process of the automatic door opening and closing device 1 and the boarding bridge 100 proposed in this application is as follows:

[0080] The remote controller activates the switch button of the automatic boarding bridge 100, and the automatic boarding bridge 100 begins to move along the prescribed trajectory. When the automatic boarding bridge 100 approaches or after approaching the door, the tightly closed double door 2 begins to open.

[0081] The motors 111 on both sides of the drive structure 10 start to rotate simultaneously, the first left connecting piece 2011 of the left door leaf 21 starts to move left under the drive of the motors 111 of the left drive assembly 101, the first left connecting piece 2011 is connected to the second left connecting piece 2012 through the hinge ear seat and is offset left, thereby dragging the left door leaf 21 to open. Under the drive of the motors 111 of the right drive assembly 102, the right connecting piece 2021 of the right door leaf 22 pushes the slider 20221 in the linear guide rail 20222 to move from the right end to the left end, thereby pushing the right door leaf 22 to open.

[0082] When the door 2 is completely opened, the ends of the door 2 push the limit switches 30 (the left first switch 301 and the right second switch 304). After the limit switches 30 send the instruction that the door 2 has been opened, the controller will start the brake system to maintain the door 2 in a stable open state.

[0083] If the automatic door opening and closing device 1 fails in the middle of opening the door 2, the motors 111 stop rotating, and the door 2 cannot be opened. At this time, the on-site personnel can use a hook or other tools to pull down the clutch hand brake 113 in the drive assembly on both sides of the door frame 23, so that the upper half 1121 and the lower half 1122 of the card coupling 112 connected with the motors 111 are separated, realizing the switching from electric drive to manual drive.

[0084] In the process of opening the door 2, the human body sensor 40 on the door frame 23 is started, and the human body sensor 40 detects the human body. When a person passes by, the human body sensor 40 can send a stop opening door signal at any time to prevent the person from being collided or pinched.

[0085] When the radar monitor detects that no one passes by for 1 minute, the remote controller will receive an inquiry whether the door needs to be closed. After ensuring that the door can be closed, the remote controller starts to close the double doors 2.

[0086] The motors 111 on both sides of the drive structure 10 start to reverse, the connection structure 20 starts to move in the opposite direction, realizing the opposite direction movement of the left door leaf 21 and the right door leaf 22, thereby realizing the closing of the door.

[0087] After the door 2 is closed, the limit switches 30 (the left second switch 302 and the right first switch 303) send a signal that the door 2 has been closed, the human body detector is closed, and the automatic boarding bridge 100 starts to withdraw from the airplane.

[0088] Third embodiment:

[0089] In combination with the accompanying drawings Figures 1 to 4 , Figures 8 to 11 , the use process of the automatic door opening and closing device 1 and the boarding bridge 100 proposed in the present application is:

[0090] The remote controller starts the switch button of the automatic boarding bridge 100, and the automatic boarding bridge 100 starts to move according to the specified track. When the automatic boarding bridge 100 approaches the door or after the approach is completed, the tightly closed double doors 2 start to open.

[0091] The manual release 116 is in the position of connecting the drive brake and the motor 111, and the drive brake is in the relaxed state.

[0092] The left and right motors 111 of the drive structure 10 start to rotate simultaneously. The left connecting component assembly 201 of the left door leaf 21 starts to move to the left under the driving of the motor 111 of the left drive assembly 101, thereby dragging the left door leaf 21 to open. The right connecting component assembly 202 of the right door leaf 22 moves under the driving of the motor 111 of the right drive assembly 102, thereby pushing the right door leaf 22 to open.

[0093] When the door 2 is completely opened, the end of the door 2 pushes the limit switch 30 (the left first switch 301 and the right second switch 304). After the limit switch 30 sends the instruction that the door 2 is opened, the controller controls the drive actuator to switch from the relaxed state to the brake state, and locks the motor 111 to maintain the door 2 in the stable open state.

[0094] If the automatic door opening device 1 fails in the middle of opening the door, the motor 111 stops rotating, and the door 2 cannot be opened. At this time, the on-site personnel can pull the manual release 116 to disconnect the drive brake and the motor 111, thereby realizing the switching from electric to manual.

[0095] During the opening of the door 2, the human body sensor 40 on the door frame 23 is activated. The human body sensor 40 detects the human body, and can send a stop opening signal at any time when a person passes by, to prevent the person from being collided or pinched.

[0096] When the radar monitor 1 minute has no one passing through, the remote controller will receive an inquiry whether the door needs to be closed. After ensuring that the door can be closed, the remote controller starts to close the double doors 2.

[0097] When the manual release 116 is in the position of connecting the drive brake and the motor 111, and the drive brake is in the relaxed state, the left and right motors 111 of the drive structure 10 start to reverse, the connecting structure 20 starts to move in the opposite direction, the left door leaf 21 and the right door leaf 22 move in the opposite direction, thereby realizing the closing of the door.

[0098] After the door 2 is closed, the limit switch 30 (the left second switch 302 and the right first switch 303) sends the signal that the door 2 is closed, the human body detector is closed, and the automatic boarding bridge 100 starts to withdraw from the airplane.

[0099] From the use process of the automatic door opening and closing device 1, it can be known that the automatic door opening and closing device 1 provided by the application drives the opening and closing of the door 2 through the driving structure 10, does not use manpower to open and close the door 2, has high automation degree, and can save manpower cost. The locking structure can keep the door 2 in a stable opening or closing state, prevent external force from changing the state of the door 2, and cause accidents. The locking structure can also keep the door 2 in a stable opening or closing state during the opening or closing process of the door 2, prevent safety accidents such as collision and pinching, and can realize remote control.
