Description

Technical Field

[0001] This utility model relates to the field of boarding bridge doors, and in particular to a multi-unit protection device for boarding bridge doors. Background Technology

[0002] Currently, the commonly used aircraft door protector for boarding bridges is called a safety boot. The safety boot consists of a single protector, which is composed of a protector base, an air bladder or sensor, a protective rubber sleeve, and a signal cable connecting to the boarding bridge. The single-unit safety boot is placed directly below the aircraft door. When the aircraft suddenly descends, it first touches the rubber protective sleeve, which then compresses the air bladder or sensor, sending a signal to the boarding bridge control system to take corresponding descent actions. However, during use, the single-unit safety boot is often accidentally touched, which can easily cause malfunctions and safety accidents. Therefore, a multi-unit protection device for boarding bridge doors is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-unit protection device for boarding bridge doors, which solves the problem that current protection devices are easily accidentally touched, causing the protection devices to automatically descend.

[0004] To achieve this objective, the present invention adopts the following technical solution: A multi-unit protection device for boarding bridge doors includes: The hatch and the base installed on the hatch, the top of the base has two openings, and the interior of each of the two openings is equipped with a protective unit; An adjustment assembly includes a mounting plate fixed to the bottom of the base and a lifting motor mounted on one side of the mounting plate. An arc-shaped gear is mounted on the other side of the mounting plate. The output end of the lifting motor passes through the mounting plate and is connected to the arc-shaped gear. An arc-shaped rack is fixed on one side of the protection unit at the position of the arc-shaped gear, and the arc-shaped gear and the arc-shaped rack mesh with each other.

[0005] Furthermore, the protection unit includes a long plate and two arc plates, with the two arc plates fixed to the bottom of the long plate one in front of the other, and the arc-shaped rack fixed to one side of the arc plates.

[0006] Furthermore, one side of the long plate is rotatably connected to the base via a hinge.

[0007] Furthermore, a contact roller is provided between the two arc plates near the long plate.

[0008] Furthermore, a detection sensor is installed on one side of the base, and the touch roller moves in accordance with the detection sensor.

[0009] Furthermore, a rotating spring is provided at the hinge between the long plate and the base, with both ends of the rotating spring fixed to the long plate and the base respectively.

[0010] Furthermore, the two protective units can be configured to flip in the same direction, or the two protective units can be arranged symmetrically along the central axis of the base.

[0011] Furthermore, a guide groove is provided on one side of one of the arc plates, and a guide rod is fixed on one side of the inner wall of the base at the position corresponding to the guide groove, with one end of the guide rod located inside the guide groove.

[0012] Furthermore, the guide groove is configured as an arc-shaped groove, which is adapted to the arc plate structure.

[0013] Furthermore, a push rod is fixedly mounted on one side of the arc-shaped rack, a push plate is fixedly mounted on the top of the arc-shaped rack, and the bottom of the push plate presses against the outside of the push rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The protection unit on the base, in conjunction with the adjustment components, ensures that the protection unit will not automatically descend when accidentally touched. The protection unit will only descend after two detection sensors are triggered. That is, the protection unit is kept in an ascending or descending state by the lifting motor through the arc gear rack mechanism. When two or more protection units are in the ascending state at the same time, the aircraft door will simultaneously touch the touch roller, causing the detection sensors to detect and sense the movement. The detection sensors will simultaneously send an action signal, which will be transmitted to the lifting motor. The lifting motor will drive the arc gear rack to descend the protection unit. If a person or object accidentally touches one of the protection units, the descent signal will not be triggered, and the protection unit will not descend.

[0015] 2. By using the guide groove and guide rod, in conjunction with the push plate and push rod, when the guide rod is located inside the guide groove, the protection unit can be guided and limited during the rising and falling process to prevent the protection unit from moving in other ways. The push plate is fixed on the arc-shaped rack. When the arc-shaped rack moves, the push plate will press the push rod, so that the protection unit can descend more stably.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model embodiment provides a multi-unit protection device for boarding bridge doors. Please refer to [link / reference]. Figures 1-8 The system includes: a cabin door and a base 1 installed on the cabin door. The top of the base 1 has two openings, and each of the two openings is equipped with a protection unit 2. The multi-unit protection device for the boarding bridge cabin door also includes an adjustment assembly. The adjustment assembly includes a mounting plate 5 fixed to the bottom of the base 1 and a lifting motor 6 installed on one side of the mounting plate 5. An arc-shaped gear 7 is mounted on the other side of the mounting plate 5. The output end of the lifting motor 6 passes through the mounting plate 5 and is connected to the arc-shaped gear 7. An arc-shaped rack 8 is fixed on one side of the protection unit at the position of the arc-shaped gear 7. The arc-shaped gear 7 and the arc-shaped rack 8 mesh with each other.

[0024] like Figures 1-8 As shown, base 1 serves as the mounting foundation for the entire protective device, fixed to the cabin door, providing a stable support platform for other components and ensuring that the entire device can be securely installed at the boarding bridge cabin door.

[0025] The two openings provide installation space for the protection unit 2, which is located inside the openings and can extend or retract when needed to protect specific areas of the hatch or related objects.

[0026] Mounting plate 5 provides a mounting base for other components of the adjustment assembly, fixing them to the bottom of base 1. Lifting motor 6 is the power source of the adjustment assembly, providing power for the adjustment action of protection unit 2. Lifting motor 6 is an electric motor used to drive mechanical devices to achieve vertical or horizontal lifting movements. At the same time, lifting motor 6 can also drive arc gear 7 to rotate. Lifting motor 6 is well known to those skilled in the art. The key point is to use lifting motor 6 to drive arc gear 7 to rotate, so that arc rack 8 moves. This will not be described in detail in this embodiment.

[0027] The arc-shaped gear 7 serves as a transmission component, converting and transmitting the rotational motion of the lifting motor 6. The output end of the lifting motor 6 is connected to the arc-shaped gear 7, enabling the motor to drive the arc-shaped gear 7 to rotate. The design of the arc-shaped gear 7 allows for a reasonable transmission design based on the motion trajectory of the protection unit 2, enabling the protection unit 2 to move in an arc shape, better adapting to the spatial structure and protection requirements around the hatch. This connection method is simple, reliable, and easy to install and maintain.

[0028] The arc-shaped rack 8 and the arc-shaped gear 7 mesh with each other to form a transmission pair, converting the rotation of the arc-shaped gear 7 into the linear or arc-shaped motion of the arc-shaped rack 8, thereby driving the protection unit 2 to perform corresponding actions. This meshing transmission method has the characteristics of accurate, smooth and reliable transmission, and can accurately control the movement position and speed of the protection unit 2, ensuring that the protection unit 2 can accurately reach the predetermined position and achieve effective protection function. At the same time, the structural design of the arc-shaped rack 8 and the arc-shaped gear 7 can adapt to the arc-shaped movement trajectory of the protection unit 2, reduce jamming and wear during the movement process, and improve the service life of the device.

[0029] Specific operation process: After the aircraft descends, both cabin doors simultaneously trigger the touch rollers 14, causing them to roll. Since the touch rollers 14 are electrically connected to the detection sensor 11, the sensor detects and senses this movement, simultaneously sending an action signal to the lifting motor 6. The lifting motor 6 drives the arc-shaped gear 7, causing the protection unit 2 to descend. If a person or object accidentally touches one of the protection units 2, the descent trigger signal is not met, and the protection unit 2 will not descend. When the position of the protection unit 2 needs to be adjusted to protect the cabin door, the lifting motor 6 is started. The output end of the lifting motor 6 starts to rotate, driving the arc gear 7 connected to it to rotate. Since the arc gear 7 meshes with the arc rack 8 on one side of the protection unit 2, the rotation of the arc gear 7 will drive the arc rack 8 to move. The movement of the arc rack 8 will drive the entire protection unit 2 to perform arc-shaped movement. The protection unit 2 extends or retracts from the opening at the top of the base 1 to prevent the aircraft cabin door from colliding with the boarding bridge access floor and protect the aircraft cabin door.

[0030] Please see Figures 1-6 The protection unit 2 includes a long plate and two arc plates. The two arc plates are fixed to the bottom of the long plate, one in front and one behind. An arc-shaped rack 8 is fixed to one side of the arc plate. One side of the long plate is rotatably connected to the base 1 via a hinge 3. A touch roller 14 is rotatably provided between the two arc plates near the long plate. A detection sensor 11 is installed on one side of the base 1. The touch roller 14 corresponds to the detection sensor 11.

[0031] like Figures 1-6As shown, the long plate serves as the main structure of the protection unit 2, providing the main support and protection area for the entire protection unit 2. It can directly block objects that may damage the hatch. Two arc plates are set at the bottom of the long plate, one in front of the other. This not only enhances the structural stability of the protection unit 2, but also allows it to adapt to obstacles of different shapes to a certain extent, providing more comprehensive protection. The arc-shaped rack 8 is fixed on one side of the arc plate and is used to mesh with the arc-shaped gear 7 in the adjustment assembly to realize the rotation adjustment of the protection unit 2, thereby changing the position and angle of the protection unit 2 to meet different protection needs.

[0032] The hinge 3 provides a rotating connection point between the long plate and the base 1, allowing the protection unit 2 to rotate around the hinge 3 as an axis. This connection method allows the protection unit 2 to smoothly extend or retract from the opening of the base 1 under the action of the adjustment component, thereby realizing the opening and closing of the protection function.

[0033] The touch roller 14 can act as a buffer and rolling contact when the protection unit 2 comes into contact with an object that may collide with it. When an object approaches or collides with the protection unit 2, the touch roller 14 will first contact the object and convert the sliding friction into rolling friction through rolling, reducing friction and reducing the degree of damage to the protection unit 2 and the object. At the same time, the touch roller 14 can also transmit the collision signal to the subsequent detection device.

[0034] The detection sensor 11 is used to detect changes in the state of the touch roller 14. When the touch roller 14 changes its position or motion state due to a collision with an object, the detection sensor 11 can sense it in time and send out corresponding signals. These signals can be transmitted to the control system so that the control system can make corresponding adjustments according to the actual situation, such as stopping the movement of the protection unit 2 or issuing an alarm.

[0035] Please see Figures 1-5 A rotating spring 4 is provided at the hinge 3 between the long plate and the base 1, and the two ends of the rotating spring 4 are fixed on the long plate and the base 1 respectively.

[0036] like Figures 1-5 As shown, the rotary spring 4 has elastic potential energy. When the long plate rotates relative to the base 1 (for example, when the protection unit 2 extends or retracts), the rotary spring 4 will be twisted and store energy. When the external force driving the long plate to rotate disappears, the rotary spring 4 can release the stored energy, provide the long plate with the power to return to the initial position, so that the protection unit 2 can be automatically reset and the protection unit 2 can always maintain an upward torque.

[0037] Please see Figures 1-8 The two protection units can be set to flip in the same direction, or the two protection units can be set symmetrically along the central axis of the base 1.

[0038] like Figures 1-8As shown, this design prevents the aircraft door from colliding with the boarding bridge during docking or service due to changes in aircraft attitude (such as sudden descent), thus protecting the expensive aircraft door from damage. For example, when the aircraft door descends and hits the protection unit 2, it will trigger its internal mechanism, thereby activating the detection switch and sending a signal to the boarding bridge control system, so that the boarding bridge can take timely evasive action (such as emergency descent).

[0039] Two protective units are symmetrically arranged along the central axis of the base 1, forming a symmetrical protective structure on both sides of the boarding bridge door, achieving balanced protection of the door in all directions. No matter which direction the external force comes from, there is a corresponding protective unit 2 to block it, thus improving the overall protective capability of the protective device.

[0040] In addition to the two different arrangement directions, the protection unit 2 also includes an upward state and a downward state. In the upward state, the protection unit 2 flips upward at the hinge 3, while in the downward state, the protection unit 2 and the base 1 are made to be in a flat state.

[0041] Please see Figures 1-6 One of the arc plates has a guide groove 9 on one side, and a guide rod 10 is fixed on one side of the inner wall of the base 1 at the position corresponding to the guide groove 9. One end of the guide rod 10 is located inside the guide groove 9. The guide groove 9 is set as an arc groove, which is adapted to the structure of the arc plate.

[0042] like Figures 1-6 As shown, when the protection unit 2 performs the flipping action, the guide rod 10 moves in the guide groove 9, providing a precise path guide for the movement of the protection unit 2. Since the protection unit 2 is rotatably connected to the base 1 through the hinge 3, relying solely on the hinge 3 connection may result in problems such as inaccurate movement direction and shaking. The cooperation between the guide rod 10 and the guide groove 9 can ensure that the protection unit 2 flips according to the predetermined arc trajectory, avoiding deviation or jamming.

[0043] The interaction between the guide rod 10 and the guide groove 9 increases the connection stability between the protection unit 2 and the base 1. When the protection unit 2 is subjected to external impact, the guide rod 10 can withstand a portion of the lateral force, preventing the protection unit 2 from deforming or being damaged due to excessive force. At the same time, it can also reduce the stress on the hinge 3 and extend the service life of the hinge 3.

[0044] The protection unit 2 rotates in an arc shape with the hinge 3 as the axis. The guide groove 9 is set as an arc groove and is adapted to the arc plate structure, which makes the guide rod 10 move more smoothly in the guide groove 9 and completely consistent with the actual movement trajectory of the protection unit 2. This can avoid friction and resistance caused by the mismatch between the shape of the guide groove 9 and the movement trajectory, and reduce energy loss and component wear.

[0045] Please continue reading. Figures 1-6A push rod 13 is fixedly mounted on one side of the arc-shaped rack 8, and a push plate 12 is fixedly mounted on the top of the arc-shaped rack 8. The bottom of the push plate 12 is pressed against the outside of the push rod 13.

[0046] like Figures 1-6 As shown, push rod 13 serves to transmit and further act on the force generated by the movement of arc rack 8. Arc rack 8 moves under the drive of arc gear 7. Push rod 13 is fixed on arc plate and associated with the position of arc rack 8. It can convert the linear or arc motion trend of arc rack 8 into a more effective pushing force for other components (such as push plate 12), making the force more precise and concentrated.

[0047] The push plate 12 is set on the top of the arc-shaped rack 8. Compared with the arc-shaped rack 8, which directly contacts other components, the push plate 12 has a larger contact area. When the arc-shaped rack 8 transmits force through the push rod 13, the push plate 12 can distribute the force more evenly to the components in contact with it, reduce local stress concentration, and avoid damage to components due to excessive local force.

[0048] The pressing contact method establishes a direct mechanical connection between the push plate 12 and the push rod 13, ensuring that the movement of the push rod 13 can be directly transmitted to the push plate 12, so that the push plate 12 can move synchronously with the movement of the push rod 13. At the same time, the pressing contact also provides a certain preload to prevent the push plate 12 and the push rod 13 from loosening or separating during the movement of the protection unit 2, ensuring the continuity and stability of force transmission.

[0049] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
