Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail vehicle door technology, specifically to a snow-blocking structure for a concealed door in a rail vehicle. Background Technology
[0002] In severe weather conditions such as wind, snow, and low temperatures, when rail vehicles are running outdoors, the wind carries snow into and traps it in the gaps between the door frames and doors. Under the combined effect of the opposing air currents—18°C inside the car and -15°C outside—some of the snow melts and then refreezes and accumulates, preventing the passenger doors of the rail vehicles from opening and closing properly and affecting the normal operation of the rail vehicles. Utility Model Content
[0003] To address the technical problem of snow and wind entering the gaps of designated vehicle interior doors and causing ice formation that affects door closure, this utility model provides a snow-blocking structure for the interior doors of rail vehicles. The addition of a deflector plate can guide air and snow, effectively preventing wind from carrying snow into the gaps of rail vehicle doors.
[0004] The technical solution adopted by this utility model is to provide a snow-blocking structure for a concealed door of a rail vehicle, including a car, a door frame installed on the car, and a left passenger door and a right passenger door installed on the door frame. The corner between the end face of the door frame facing outward and the end face of the inner perimeter of the door frame is inclined. It also includes a guide plate erected on the inclined surface of the door frame. The guide plate has a triangular structure with an arc-shaped hypotenuse, and the arc surface of the guide plate faces outward.
[0005] The guide plate has a hollow structure.
[0006] The deflector plate includes a base plate, a side plate fixed to one end of the base plate, and an arc plate disposed between the other end of the base plate and the other end of the side plate. The outer end face of the side plate is fixed to the inclined surface of the door frame. The arc plate faces outward from the carriage, and the base plate faces the door.
[0007] A reinforcing plate is fixed between the base plate and the arc plate.
[0008] The reinforcing plates are at least two in number and are fixed at different angles.
[0009] The angle between the base plate and the side plate shall not exceed 90°.
[0010] It also includes a first and a second spoiler strip installed on the opposite end faces of the left and right passenger doors. The ends of the first and second spoiler strips facing inward are flush with the door frame, and the ends facing outward protrude outward.
[0011] It also includes a door frame sealing strip installed on the end face of the door frame facing the inside of the carriage, and door tail sealing strips installed on the opposite end faces of the left passenger door and the right passenger door respectively. The door frame sealing strip is located between the door frame and the left passenger door, and between the door frame and the right passenger door. The end of the door tail sealing strip facing the inside of the carriage is flush with the left passenger door or the right passenger door, and the end of the door tail sealing strip facing the door frame protrudes outward and is located inside the door frame sealing strip and abuts against the door frame sealing strip.
[0012] The beneficial effect of this utility model is that it provides a snow-blocking structure for the concealed door of a rail vehicle. During the specified vehicle operation, the airflow pattern and state of the door area are sorted and guided by the deflector plate, so that wind and snow will not flow into the gap of the door, effectively preventing wind and snow from entering and lingering in the gap of the door, and ensuring the normal operation of the rail vehicle in severe weather such as wind, snow and low temperature.

Detailed Implementation
[0016] like Figure 1-2 As shown, this utility model provides a snow-blocking structure for a concealed door of a rail vehicle, including a car body, a door frame 1 installed on the car body, and a left passenger door 2 and a right passenger door 3 installed on the door frame 1. The corner between the end face of the door frame 1 facing outwards from the car body and the inner circumference end face of the door frame 1 is an inclined surface 4. The feature is that it also includes a guide plate 5 erected on the inclined surface 4 of the door frame 1. The guide plate 5 has a triangular structure with an arc-shaped hypotenuse, and the arc surface of the guide plate 5 faces outwards from the car body.
[0017] This design is mainly applied to the concealed doors of rail vehicles. The inner circumference of the existing rail vehicle door frame 1 is concave, forming a sloping surface 4. The door is a double door. This snow-blocking structure adds a deflector 5 to the sloping surface 4 of the door frame 1. The arc surface of the deflector 5 can guide the wind and snow blowing towards the door, sorting and guiding the airflow pattern and state in the door area, so that the wind and snow will not flow into the gap of the door. The deflector 5 with an arc surface structure can reduce wind resistance while guiding the airflow, greatly reducing the wind resistance generated by adding the deflector 5 and reducing the burden on the rail vehicle.
[0018] like Figure 1-2 As shown, the guide plate 5 has a hollow structure.
[0019] Hollow-structured deflectors can reduce their weight, making production and transportation easier and reducing production costs.
[0020] like Figure 1-2 As shown, the deflector 5 includes a base plate 6, a side plate 7 fixed to one end of the base plate 6, and an arc plate 8 disposed between the other end of the base plate 6 and the other end of the side plate 7. The outer end face of the side plate 7 is fixed to the inclined surface 4 of the door frame 1. The arc plate 8 faces outward from the carriage, and the base plate 6 faces the door.
[0021] The specific structure of the deflector 5 is defined, which is simple, lightweight, easy to produce, and low in cost. The installation direction of the deflector 5 is also defined, which further ensures the effect of reducing wind resistance while guiding the airflow.
[0022] like Figure 1-2 As shown, a reinforcing plate 9 is fixed between the base plate 6 and the arc plate 8.
[0023] The reinforcing plate 9 can improve the strength of the guide plate 5.
[0024] like Figure 1-2 As shown, there are at least two reinforcing plates 9 with different fixed angles.
[0025] The strength of the guide plate 5 has been further improved.
[0026] like Figure 1-2 As shown, the angle between the base plate 6 and the side plate 7 is no higher than 90°.
[0027] This further ensures that the deflector 5 not only guides the wind and snow but also reduces wind resistance.
[0028] like Figure 1-2 As shown, it also includes a first deflector strip 10 and a second deflector strip 11 disposed on the opposite end faces of the left passenger door 2 and the right passenger door 3. The ends of the first deflector strip 10 and the second deflector strip 11 facing the inside of the carriage are flush with the door frame 1, and the ends facing the outside of the carriage protrude outward.
[0029] The first and second deflector strips 10 and 11 further enhance the snow-blocking effect, preventing wind and snow from entering between the doors from other directions.
[0030] like Figure 1-2As shown, it also includes a door frame sealing strip 12 disposed on the end face of the door frame 1 facing the interior of the carriage, and door tail sealing strips 13 disposed on the opposite end faces of the left passenger door 2 and the right passenger door 3. The door frame sealing strip 12 is located between the door frame 1 and the left passenger door 2, and between the door frame 1 and the right passenger door 3. The end of the door tail sealing strip 13 facing the interior of the carriage is flush with the left passenger door 2 or the right passenger door 3. The end of the door tail sealing strip 13 facing the door frame 1 protrudes outward and is located inside the door frame sealing strip 12 and abuts against the door frame sealing strip 12.
[0031] The door frame sealing strip 12 and the door tail sealing strip 13 further improve the snow-blocking effect and can prevent wind and snow from entering between the doors from other directions.
