Description

Technical Field

[0001] The invention relates to the technical field of windshields, in particular to a cold-resistant windshield for rail transit. Background Art

[0002] The windshield of a rail transit vehicle is a key component that connects two carriages. It is mainly used to ensure the safety of passengers, isolate the external environment (such as wind, rain, snow, noise, etc.), and adapt to the relative displacement of the vehicle during operation. Traditional windshields usually adopt a folding shed structure, including an outer folding shed and an inner folding shed. The outer folding shed is responsible for protecting the harsh external environment, and the inner folding shed ensures the sealing and stability of the passage. In addition, the windshield must be equipped with a ferry mechanism to achieve a smooth transition when the carriages are docked. As rail transit expands to harsh environments such as high cold and high humidity, higher requirements are placed on the cold resistance, durability and degree of automation of windshields.

[0003] However, the outer bellows are exposed to rain and snow for a long time, and debris is easily accumulated in the creases and grooves, especially when used in the colder north. Cold weather can easily cause aging of the outer bellows' materials and degradation of their protective performance. In addition, the ferry is usually required to be clamped between the pedals of the two car bodies and relies on traditional ferry adjustments. Therefore, when multiple carriages are connected, they need to be done one by one, which is time-consuming and inconvenient for staff to operate in the cold winter. In addition, the single drive mechanism requires precise synchronous control during docking, otherwise it is easy to be misaligned or stuck, affecting traffic efficiency. For this reason, a cold-resistant rail transit windshield is needed to solve the existing deficiencies. Summary of the invention

The guide rod 802 runs through the rotating shaft of the ferry board 7, and the guide rod 802 is movably connected to the ferry board 7. The cross-section of the middle position of the guide rod 802 is rectangular, so that the ferry board 7 can move along the length direction of the guide rod 802, and when the guide rod 802 rotates, the ferry board 7 rotates synchronously.

[0026] Start the servo motor 12 to drive the gear 805 to rotate. Since the gear 805 is meshed with the toothed belt 804, the toothed belt 804 is driven to move inside the aisle frame 6. Since the two racks 803 are meshed with the inner side of the toothed belt 804, the two racks 803 move simultaneously and in opposite directions, so that the movable frame 801 moves synchronously with the racks 803, thereby controlling the two ferry boards 7 to move simultaneously and in opposite directions at the top and bottom of the aisle frame 6.

[0028] Start the servo motor 2 13 on the top of the aisle frame 6 to drive the gear 2 1007 to rotate. Since the gear 2 1007 is meshed with the toothed belt 2 1008, the toothed belt 2 1008 moves inside the aisle frame 6, thereby controlling the gear 2 1007 at the bottom of the aisle frame 6 to rotate synchronously, realizing the synchronous rotation of the two worms 1006, and then realizing the rotation of the worm wheel 1005 and the synchronization rod 1001, so that the synchronization wheel 1002 at both ends of the synchronization rod 1001 rotates, and under the action of the synchronization belt 1004, the guide rod 802 is controlled to rotate, thereby controlling the ferry board 7 to rotate around the guide rod 802, thereby controlling the bottom of the aisle frame 6 and the ferry board 7 at the bottom to flip outward to the inside of another car body 1, and similarly operate the ferry board 7 of the other car body 1 to flip to the inside of the car body 1, thereby completing the docking of the ferry boards 7 of the two car bodies 1, which is conducive to realizing the automated operation of the docking of the ferry boards 7 between the car bodies 1.

Then, the servo motor 12 is started to drive the gear 805 to rotate. Since the gear 805 is meshed with the toothed belt 804, the toothed belt 804 is driven to move inside the aisle frame 6. Since the two racks 803 are meshed with the inner side of the toothed belt 804, the two racks 803 move at the same time and in opposite directions, so that the moving frame 801 moves synchronously with the racks 803, thereby controlling the two ferry boards 7 to move at the top and bottom of the aisle frame 6 at the same time and in opposite directions. The opposite car body 1 synchronously controls the ferry board 7 to move, and the bottom of the two car bodies 1 and the ferry board 7 at the bottom are in a staggered state. state, then, start the servo motor 2 13 on the top of the aisle frame 6, drive the gear 2 1007 to rotate, because the gear 2 1007 is meshed with the toothed belt 2 1008, so that the toothed belt 2 1008 moves inside the aisle frame 6, thereby controlling the gear 2 1007 at the bottom of the aisle frame 6 to rotate synchronously, realizing the synchronous rotation of the two worms 1006, and then realizing the rotation of the worm wheel 1005 and the synchronization rod 1001, so that the synchronization wheel 1 1002 at both ends of the synchronization rod 1001 rotates, and under the action of the synchronization belt 1004, the guide rod 802 is controlled to rotate, thereby controlling the ferry board 7 to rotate around the guide rod 802, thereby controlling the bottom of the aisle frame 6 and the ferry board 7 at the bottom to flip outward to the inside of another car body 1, and similarly operate the ferry board 7 of the other car body 1 to flip to the inside of the car body 1, thereby completing the docking of the ferry boards 7 of the two car bodies 1.
