Description

Technical Field

[0001] This utility model belongs to the field of railway train technology and relates to a multi-functional viewing window for tourist trains. Background Technology

[0002] The viewing windows of tourist trains generally need to meet multiple requirements. For safety, they use reinforced or bulletproof glass capable of withstanding impacts and pressure to ensure passenger safety. They offer a large field of vision with frameless or narrow-frame designs to broaden the view. They feature UV protection to protect passengers while ensuring adequate interior lighting. They have good heat and sound insulation to reduce the impact of external temperature and running noise, improving comfort. They can be opened or have special cleaning mechanisms for easy ventilation and window cleaning. Structurally, they are tightly integrated with the train body to ensure stability and prevent swaying at high speeds or under different road conditions. Aesthetically, they coordinate with the overall appearance of the train. They are well-sealed, waterproof, and dustproof, keeping the interior of the carriage clean and dry. The materials are highly weather-resistant, resisting sunlight, wind erosion, rain, and snow, ensuring long-term use. Their opening, closing, and adjustment systems are easy to operate and suitable for passengers of different ages and physical conditions.

[0003] Therefore, the main functional requirements for the viewing window system include: (a) the viewing window glass has a heating and defrosting function; and (b) it has a good viewing view. However, at present, the existing viewing windows cannot meet the growing cultural tourism and photo-taking needs of railway tourist train users, and the modification of the windows poses a great challenge to the safety of vehicle operation and the compliance of various calculation parameters.

The short column 17 is bent into a "channel" structure by a 4-Q3355GNHD steel plate, and its structure is the same as that of the short cross beam 15.

[0060] The window pillars 11 and reinforcing pillars 12 are located on the left and right sides of the alloy window frame 1, with the reinforcing pillar 12 welded to the side of the window pillar 11 away from the glass 2. The window pillars 11 and reinforcing pillars 12 together serve as the vertical support structure for the viewing window. The window beams 13 and reinforcing beams 14 are located horizontally on the upper and lower sides of the alloy window frame 1, with the reinforcing beam 14 welded to the side of the window beam 13 away from the interior of the viewing vehicle. The window pillars 11 and reinforcing pillars 12 together serve as the horizontal support structure for the viewing window. The left and right ends of the window beams 13 and reinforcing beams 14 are welded and fixed to the window pillars 11. The pillars of the window pillars 11 and reinforcing pillars 12 are welded to the two end walls via several short beams 15, and the beams of the window beams 13 and reinforcing beams 14 are welded to the two end walls via several short pillars 17. The upper ends of the window pillar 11, reinforcing pillar 12, and short pillar 17 are welded to the end wall side beams of the two end walls, and the lower ends are welded to the base frame side beams of the two end walls; the short crossbeam 15 is welded to the corner pillars of the two end walls. The end wall side beams and base frame side beams are located at the upper and lower ends of the two end walls, respectively; the corner pillars are located at the left and right ends of the two end walls.

[0061] Both the first window frame fixing structure 3 and the second window frame fixing structure 4 are composed of a clip structure and a machine screw structure. These are two different fixing methods, as shown below. Figure 3 and Figure 4 As shown. Figure 2 The left side of the mid-section view shows a schematic diagram of the card structure and the machine screw structure in the same horizontal or vertical position.

[0062] Figure 3 As shown, the clip structure includes a clip 10 and bolts disposed on the clip 10; the clip 10 is engaged with the dovetail groove of the alloy window frame 1 by a dovetail boss, and the dovetail boss and the dovetail groove are slidably engaged; the clip 10 is provided with bolts perpendicular to the plane of the glass 2, and tightening the bolts will press down the window pillar 11 / window beam 13, the two end walls and the alloy window frame 1 in sequence.

[0063] like Figure 4 As shown, the screw structure is a threaded locking structure. Holes are drilled around the perimeter of the steel structure, and screws 5 (imitation gold countersunk cross-head screws - M6) are passed sequentially through pre-drilled mounting holes on the alloy window frame 1, corresponding holes in the two end walls, through holes on the window pillar 11 / window beam 13, and corresponding through holes on the window reinforcement plate 16, along with flat washers 8 (nominal size 6mm) and spring washers 7 (nominal size 6mm), and finally screwed into nuts 6 (type 1 hexagonal nuts M6) to achieve a fixed connection between the window frame and the two end walls.

[0064] (II) Temperature control modifications to the viewing window structure:

[0065] Inside the electrical control cabinet of the multi-functional vehicle, a main air switch for the viewing window power supply is installed. Its rated current is 16A, clearly marked as "Glass Heating," and it controls the current flow of the viewing window glass heating circuit. Simultaneously, a heating auxiliary control device—thermostat 9—is installed on glass 2 (see...). Figure 3 A glass heating resistor is installed every 20cm in the interlayer adhesive layer of the glass 2, and the glass heating resistor is connected to the thermostat 9. The thermostat 9 is connected to the vehicle's power supply, which is an AC220V power supply device. After the power is turned on, the glass heating resistor works normally and stably to heat the glass 2. When the temperature reaches 40℃, the thermostat 9 senses the high temperature, disconnects the circuit, and the heating stops.

[0066] Wiring is based on the requirements of the electric double-opening viewing window system. The power supply cable is WDZ-DC-900.6 / 1kV 2.5mm², conforming to the requirements of "Railway Passenger Car Cables" (Q / CR 814-2021). 2 M-cables should be protected with nylon flexible conduits conforming to the "Provisional Technical Conditions for Nylon Flexible Conduits and Nylon Flexible Conduit Joints for Railway Passenger Cars" (TJ / CL430-2014). All terminals should be securely crimped and marked with wire numbers. The wiring scheme should comply with the provisions of TB / T1759-2016 "Rules for Wiring and Cabling of Railway Passenger Cars." Vehicle wiring should be crimped to the corresponding wire numbers on the terminal blocks inside the junction box.

[0077] (3) Condition 3: 3g longitudinal impact condition at two end walls (e.g.) Figure 17 , Figure 18 Load: ① A longitudinal load of 3g*M4 is applied to the two end walls. Constraints: Lateral, longitudinal, and vertical constraints are applied around the two end walls.

[0078] Figures 13-18 The results show that the steel structure at the viewing window meets the strength requirements.
