The glass doors of the boarding bridges, being a key component for personnel entering and exiting the aircraft, must meet various performance requirements.

[0003] Currently, the glass doors on common boarding bridges still have shortcomings:

[0004] 1. In terms of thermal insulation performance, it cannot effectively reduce heat transfer in cold or hot weather, resulting in the internal temperature of the boarding bridge being greatly affected by the external environment, which increases energy consumption;

[0005] 2. In terms of fire prevention, in the event of a fire, the existing glass doors are unlikely to effectively prevent the spread of fire, posing a serious threat to personnel safety and airport facilities;

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 This utility model provides a technical solution:

[0027] A boarding bridge glass door includes:

[0028] The main structure includes a door frame 1 and a door leaf 2. The door leaf 2 is installed inside the door frame 1 and includes a frame 9 and a glass panel. A handle 7 is provided on the frame 9 of the door leaf 2. The door leaf 2 is installed inside the door frame 1 through a top and bottom pivot 4 to realize the opening and closing function of the door leaf 2. Two doors 2 are installed inside the door frame 1. A sequencer 5 is provided between the top of the door leaf 2 and the door frame 1 to ensure that the door leaf 2 can automatically close in a specific order during opening and closing, avoiding mutual interference between the door leaves 2. The door leaf 2 and the door frame 1 are also provided with a door closer 6 to automatically close the door after the door leaf 2 is opened, ensuring that the door can automatically return to the closed state without manual intervention.

[0029] Among them, the top and bottom hinges 4, the sequencer 5, and the door closer 6 are all common products in existing technology and can be purchased from the market for installation and use. They will not be described in detail here.

[0030] The glass panel is designed to be fire-resistant. Specifically, the glass panel uses fire-resistant glass, and in this embodiment, either wired fire-resistant glass or composite fire-resistant glass can be used. Wired fire-resistant glass has metal wires embedded inside the glass. When the glass breaks due to heat, the metal wires can prevent glass fragments from flying and maintain a certain degree of integrity, preventing the spread of fire. Composite fire-resistant glass consists of multiple layers of glass and a fire-resistant adhesive layer. In the event of a fire, the fire-resistant adhesive layer expands when heated, forming a heat insulation barrier that effectively prevents the spread of heat and flames. For example, in this embodiment, using wired fire-resistant glass with a thickness of 10mm-15mm or composite fire-resistant glass composed of two 5mm glass layers and a 3mm fire-resistant adhesive layer can meet the stringent fire resistance requirements of airport boarding bridges.

[0031] Please see Figure 1-2 :

[0032] Both the door frame 1 and the frame 9 are high-strength aluminum alloy frame structures with thermal break design, and are filled with thermal insulation material. Fireproof sealing strips 11 are bonded to the edges and gaps of the glass panel, frame 9 and door frame 1.

[0033] Specifically, fire-resistant sealing strips 11 are installed along the edges and gaps of the glass door. These strips have good elasticity and sealing properties at room temperature, effectively preventing air leakage. In the event of a fire, the strips expand when heated, further filling the gaps to form a tight fire-resistant seal, preventing smoke and flames from spreading through the gaps. The fire-resistant sealing strips 11 can be made of silicone rubber with added flame retardants and expanding agents to improve their fire resistance.

[0034] Specifically, the structural strength of the glass door has been optimized, employing a high-strength aluminum alloy frame. The cross-sectional shape and dimensions of the frame are rationally designed based on mechanical calculations to ensure that the glass door will not deform or be damaged when subjected to significant external forces. For example, in this embodiment, the frame wall thickness can be designed to be 3mm-5mm, and the strength grade of the aluminum alloy material is not lower than 6063-T5, which effectively improves the wind pressure resistance and impact resistance of the glass door.

[0035] Please see Figure 1-2 :

[0036] In the thermal break design of door frame 1 and frame 9, the inner frame and outer frame are connected by a thermal break strip, thereby blocking the heat conduction path through the frame.

[0037] Specifically, high-efficiency thermal insulation material, such as polyurethane foam, is installed at the frame 9 of the glass door. The door frame 1 and the frame 9 employ a thermal break design, connecting the inner and outer frames 9 with a thermal break strip to block heat conduction through the frame 9. In this embodiment, the thermal break strip can be made of nylon 66 with glass fiber reinforcement, which has good thermal insulation performance and high strength and durability. This frame 9 design further reduces the overall heat loss of the glass door and improves the insulation effect inside the boarding bridge.

[0038] Please see Figure 1-2 :

[0039] The glass panel in door leaf 2 adopts a multi-layer vacuum glass structure with an internal vacuum layer filled with inert gas to reduce the heat transfer coefficient of the glass and reduce the heat transfer through conduction and convection.

[0040] The glass panel employs a multi-layered insulated glass structure, with the hollow layer 10 filled with an inert gas, such as argon in this embodiment. This design effectively reduces the heat transfer coefficient of the glass, minimizing heat transfer through conduction and convection. For example, in this embodiment, the thickness of the hollow layer 10 can be designed to be 12mm-20mm, with an argon filling rate exceeding 90%. Testing has shown that this improves the thermal insulation performance of the glass door by 3-5 times compared to ordinary single-layer glass.

[0041] Please see Figure 1-2 :

[0042] The main structure also includes an anti-pinch protection system, which includes an infrared sensor 8 and a pressure sensor. The infrared sensor 8 is set on the inside of the door frame 1 to monitor human activity near the glass door in real time and control the opening and closing of the door leaf 2 accordingly. The pressure sensor is installed on the edge of the door leaf 2. When the door leaf 2 is subjected to a certain pressure during the closing process, a signal is triggered to make the door leaf 2 move in the opposite direction to avoid the occurrence of pinching accidents.

[0043] The infrared sensor 8 includes a transmitter and a receiver, which are respectively installed on the inner walls of both sides of the door frame 1. The transmitter emits a safety light 3 from the receiver to detect human activity.

[0044] During operation, the infrared sensor 8 monitors human activity near the glass door in real time. When it detects someone entering a dangerous area, it promptly stops the glass door from closing or reopens it. A pressure sensor is installed on the edge of the glass door. When the door is subjected to pressure during closing, if a person or object is caught, the sensor immediately triggers a signal, causing the glass door to move in the opposite direction, preventing pinching accidents. The anti-pinch protection system's response time can be controlled within 0.1 seconds, ensuring personnel safety.

[0045] In addition, clearly visible safety signs and emergency escape instructions are installed on the glass doors.

[0046] Specifically, the safety signs are made of reflective material, ensuring clear visibility even in low-light conditions and alerting passengers to safety. Emergency escape signs automatically illuminate in the event of a fire or other emergency, guiding passengers quickly to the escape route. For example, in this embodiment, the brightness of both the safety signs and emergency escape signs is no less than 50 cd / m². 2 It also has good weather resistance and wear resistance.

[0047] This application also includes the glass door manufacturing process, as detailed below:

[0048] S1. Fabrication of multi-layer insulated glass:

[0049] First, the cut glass sheets are cleaned and dried to ensure the glass surface is free of impurities. Then, sealant is applied to the glass edges, and spacers are installed along the edges to form the gaps in the insulated glass layer 10. Next, the insulated glass layer 10, filled with argon gas, is assembled, and sealant is applied again to ensure its airtightness. Finally, the manufactured multi-layer insulated glass undergoes quality testing, including tests for airtightness, watertightness, and thermal insulation performance.

[0050] S2. Aluminum Alloy Frame Fabrication: Based on design requirements, aluminum alloy profiles are cut, drilled, and milled to produce frame components that meet dimensional requirements. Then, surface treatments such as anodizing are applied to the frame components to improve the corrosion resistance and aesthetics of the aluminum alloy. The fabricated frame components are then assembled into a complete frame using welding or bolting.

[0051] S3. Installation of Fire-Resistant Sealing Strip 11 and Safety Signs: Apply fire-resistant sealant evenly to the edges and gaps of the frame, and then attach the fire-resistant sealing strip 11 to the corresponding positions, ensuring a tight fit between the strip and the frame. Use specialized adhesive to attach safety signs and emergency escape route signs in prominent positions on the glass door, ensuring the signs are secure and accurately positioned.

[0052] S4. Anti-pinch protection system installation: Install the infrared sensor 8 and pressure sensor on the glass door frame 9 according to the designed positions, and connect the sensor signal lines and power lines. Debug the anti-pinch protection system to ensure that the sensor sensitivity and response time meet the design requirements.

[0053] S5. Glass door installation and debugging:

[0054] Install a fixed bracket on the door frame 1 of the boarding bridge, and install the finished glass door onto the fixed bracket using hoisting equipment. Adjust the position and level of the glass door to ensure that the gap between the glass door and the door frame 1 is uniform.

[0055] Connect the drive unit and control system of the glass door to test its opening and closing functions. During the test, check whether the glass door operates smoothly and whether there are any jams or abnormal noises. At the same time, perform a functional test on the anti-pinch protection system, simulating a person or object entering the dangerous area, and check whether the glass door can respond in a timely manner.

[0056] On-site testing was conducted on the thermal insulation and fire resistance performance of the glass door. The temperature difference between the inner and outer surfaces of the glass door was measured under different ambient temperatures to evaluate its thermal insulation performance. Fire simulation tests were performed to observe the fire resistance of the glass door under flame conditions, including whether the fire was effectively contained and whether the glass door remained intact. Based on the test results, necessary adjustments and optimizations were made to the glass door to ensure that its performance indicators met the design requirements.

[0057] In summary, it has the following advantages:

[0058] 1. The high-strength aluminum alloy frame with thermal break design is filled with insulation material to effectively block the heat conduction path through the frame; the glass panel adopts a multi-layer vacuum glass structure and is filled with inert gas, which significantly reduces the heat transfer coefficient of the glass and reduces the heat transfer through conduction and convection, thereby improving the insulation effect inside the boarding bridge and reducing energy consumption.

[0059] 2. The glass panels are made of fire-resistant glass, such as wired fire-resistant glass or composite fire-resistant glass, which can effectively prevent the spread of fire in the event of a fire and protect personnel safety and airport facilities; fire-resistant sealing strips 11 are installed at the edges and gaps of the glass doors, which form a tight fire-resistant seal after being heated and expanding, preventing smoke and flames from spreading through the gaps.

[0060] 3.
