[0037] A trumpet-shaped drainage structure 3 is embedded in the foot pedal mounting frame 2.

[0038] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0039] Referring to Figures 1-4 The embodiments of the present application provide a foot pedal area rapid drainage structure, which comprises:

[0040] A foot pedal mounting frame 2;

[0041] A trumpet-shaped drainage structure 3 embedded in the foot pedal mounting frame 2;

[0042] A foot pedal isolation cover plate 1 arranged on the top surface of the foot pedal mounting frame 2, and the trumpet-shaped drainage structure 3 is located in the area of the foot pedal mounting frame 2 covered by the foot pedal isolation cover plate 1;

[0043] The trumpet-shaped drainage structure 3 comprises:

[0044] A water guide assembly 30 embedded on the top surface of the foot pedal mounting frame 2, the water guide assembly 30 is an open structure with an inclined inner wall, the edge of the open structure of the water guide assembly 30 is rectangular or circular, and the inclined surface of the water guide assembly 30 is inclined from outside to inside;

[0045] A bowl-shaped water collecting assembly 31 arranged in the foot pedal mounting frame 2 and communicating with the water guide assembly 30, the bowl-shaped water collecting assembly 31 is a bowl-shaped structure with a wide top and a narrow bottom, and the top and bottom surfaces are both provided with openings;

[0046] A trumpet-shaped drainage assembly 32 arranged in the foot pedal mounting frame 2 and communicating with the bottom surface opening of the bowl-shaped water collecting assembly 31, the trumpet-shaped drainage assembly 32 is a trumpet-shaped structure with a narrow top and a wide bottom, and the top and bottom surfaces are both provided with openings, and the bottom surface opening of the trumpet-shaped drainage assembly 32 is located outside the bottom surface of the foot pedal mounting frame 2.

[0047] The embodiments of the present application based on the trumpet-shaped drainage structure meet the drainage requirements of the rail vehicle, have simple structure, low cost, and effectively realize the rapid emptying of the foot pedal area space water.

[0048] Further, the top surface of the foot pedal mounting frame 2 is provided with a mounting frame opening 20 with an inclined inner wall;

[0049] The water guide assembly 30 communicates with the bottom surface of the mounting frame opening 20.

[0050] As shown in the drawingsFigure 1 As shown, the structure is installed near the side wall panel 4 of the rail vehicle.

[0051] The technical solution of the embodiment of the present application is designed to solve the problem of quickly draining water accumulated in the footrest area, and to this end provides a fast drainage structure with fast drainage speed, simple structure and simple machining process.

[0052] The rapid drainage structure of the pedal area includes a pedal isolation cover plate 1, a pedal mounting frame 2, and a bell-shaped drainage structure 3;

[0053] The bell-shaped drainage structure 3 integrates the installation interface and is installed at the lowest point of the top surface structure of the footrest mounting frame 2. Its water outlet is designed to be bell-shaped, and a water storage tank is provided above the water outlet on the top of the bell-shaped drainage structure 3.

[0054] The footrest area rapid drainage structure is located in the footrest area of ​​the vehicle door opening. The footrest isolation cover plate 1 is installed on the footrest mounting frame 2 and is sealed to isolate the footrest installation space from the vehicle interior space.

[0055] Since the footrest isolation cover plate 1, the trumpet-shaped drainage structure 3 and the footrest mounting frame 2 are all installed in a sealed manner, the discharge channel of the accumulated water is unidirectional. When the accumulated water is at the lowest point of the footrest mounting space, it will flow to the water trough above the outlet of the drain pipe 3, and then be discharged to the outside of the vehicle through the trumpet-shaped outlet of the trumpet-shaped drainage structure 3.

[0056] The drainage structure provides a special fast drainage channel with fast drainage speed and simple installation, thereby realizing the rapid emptying of water accumulated in the footrest area space.

[0057] As the diameter of the water outlet channel of the trumpet-shaped drainage structure 3 gradually increases, the drainage flow rate per unit time is increased, thereby achieving rapid drainage of water accumulated in the footrest area space.

[0058] By optimizing the model and processing technology of the trumpet-shaped drainage structure, a fast drainage structure design is achieved, which accelerates the drainage speed of the footrest area, thereby achieving rapid emptying of water accumulated in the footrest area.

[0059] The technical solution of the embodiment of the present application also solves, to a certain extent, the problem of water accumulation and freezing in the drainage structure of the footrest area when the train is running in severe cold weather. The trumpet-shaped drainage structure 3 allows the water to flow outward along the trumpet-shaped outlet line, making it difficult for water droplets to gather at the outlet, thereby avoiding the possibility of water accumulation and freezing due to poor water fluidity in severe cold weather.

[0060] As shown in the accompanying drawings Figures 1-4 As shown, the bottom of the bell-shaped drainage structure 3 of the rapid drainage structure in the footrest area is directly connected to the atmosphere;

[0061] The trumpet-shaped drainage structure 3 is installed on the foot pedal mounting frame 2, and the foot pedal isolation cover plate 1 is tightly connected with the foot pedal mounting frame 2;

[0062] The foot pedal isolation cover plate 1, the foot pedal mounting frame 2 and the trumpet-shaped drainage structure 3 form a water accumulation discharge channel, and all positions except the trumpet-shaped drainage structure 3 of the water collection port in the vehicle and the foot pedal area are in a sealed state, which ensures that the water accumulation can only be discharged from the trumpet-shaped drainage structure 3 of the foot pedal area.
