[0002] With the vigorous development of urban transportation in China, high-speed EMUs running between different cities have become an indispensable part of rail transportation. Usually, the train whistle is installed on both sides of the front hook of the head car in the structure where the hook is exposed. With the increase in the speed of the train, in order to reduce air resistance, an opening and closing mechanism is usually set at the front of the train. When the opening and closing mechanism is opened, it is used for coupling. When the opening and closing mechanism is closed, the front of the train presents a complete streamlined structure, which effectively reduces the air resistance of the front of the train. At the same time, it also brings the problem of blocking the sound of the train whistle, making the sound of the whistle fail to meet the standard requirements. Therefore, a new structure came into being, that is, the vehicle whistle is installed on the top of the driver's cab. This structure needs to take into account the maintenance of the whistle, the installation strength of the whistle and the drainage requirements. At the same time, the installation structure should be able to meet the requirements of protecting the whistle from damage when encountering bad weather during vehicle operation.

[0028] The whistle installation structure on the top of the rail vehicle driver's cab is welded by curved aluminum plates, and a valve for repairing the whistle is provided. The curved aluminum plate includes a transition seat 3, a U-shaped plate 2, a mounting plate 5, a sealing plate 6 and four drain pipes 4; the valve includes a front inspection door 1 and a rear inspection door 7; Figure 1 and Figure 2 As shown in the structure, the structure for installing the whistle is set at the top of the vehicle body and is welded to the front frame and the front aluminum skin. The position of the rear inspection door 7 is as shown in Figure 1 shown.

[0029] like Figure 3 As shown in the structure, the whistle installation structure includes a transition seat 3, a U-shaped plate 2, a mounting plate 5, a sealing plate 6, a drain pipe 4, and a front inspection door 1; wherein the transition seat 3, the U-shaped plate 2, the mounting plate 5, the sealing plate 6, and the drain pipe 4 are welded together to form a whole, and finally welded to the front aluminum skin and the frame and fixed in the front of the vehicle. The front inspection door 1 and the rear inspection door 7 are fixed to the front of the vehicle by M8 countersunk screws. The materials involved in the utility model are all aluminum alloy 5083-H111.

[0030] The utility model takes into account the sealing performance of the whistle installation structure and the vehicle body, the effective drainage and the functions of rapid maintenance. The sealing performance is achieved by fully welding the U-shaped plate 2, the front sealing plate 6, the rear sealing plate 6 and the front skin to achieve the sealing performance of the whistle installation structure and the interior of the driver's cab. The effective drainage is achieved by tilting the U-shaped plate 2 at 5° with the horizontal plane. When the train is stationary, rainwater enters the U-shaped plate 2 from the oblong hole of the front inspection door 1, and the water is discharged out of the vehicle through the groove at the front end of the U-shaped plate 2. When the train is running, rainwater will enter the U-shaped plate 2 from the oblong hole of the front inspection door 1. Due to the inertia of the vehicle, the accumulated water flows backward relative to the front of the vehicle and is discharged out of the vehicle through four drainage pipes 4. In this process, part of the rainwater will enter the installation plate 5 from the U-shaped plate 2, and flow back to the U-shaped plate 2 through the drainage port below the installation plate 5 and then be discharged to the outside of the vehicle body. Rapid maintenance is achieved by installing the front inspection door 1 and the rear inspection door 7 to achieve the requirements of rapid cleaning of the sound outlet channel and rapid replacement of the whistle.

[0031] The various parts of the whistle installation structure are shown in the figure below: Figure 4-Figure 11 As shown, the U-shaped plate 2 is connected to the front aluminum skin through the transition seat 3. The arc of the contact surface between the transition seat 3 and the front aluminum skin is consistent with the vehicle body, which does not affect the overall shape of the front of the vehicle. The thickness of the transition seat 3 at the contact point with the front aluminum skin reaches 25 mm, which is conducive to welding the skin and the transition seat 3, and is conducive to drilling holes to embed the screw sleeves for the bolt connection of the front inspection door 1. A drainage outlet is set at the front end of the transition seat 3, and the accumulated water flows out of the vehicle from the drainage outlet during parking.

[0032] The U-shaped plate 2 is an important component of the sound outlet channel of the whistle. The U-shaped plate 2 is inclined downward at 5° with the horizontal plane, which is conducive to the drainage of rainwater entering from the front inspection door 1 out of the vehicle body, and is fully welded with the transition seat 3 and the aluminum skin of the vehicle body to isolate the interior of the driver's cab. Four drainage pipes 4 are arranged at the rear of the U-shaped plate 2, which is conducive to the drainage of accumulated water when the vehicle is running at high speed in rainy weather. There is no other structure inside the U-shaped plate 2, which creates a sound transmission channel, which is conducive to the sound intensity emitted by the whistle meeting the TSI standard requirements.

[0033] The mounting plate 5 is provided for the installation of the whistle, and the mounting plate 5 provides a mounting hole for it. The mounting plate 5 is welded to the U-shaped plate 2 and the vehicle body to isolate the interior of the driver's cab. A drain port is provided at the bottom of the mounting plate, which can drain water into the U-shaped plate 2 and finally drain it to the outside of the vehicle body from the drain pipe 4.

[0034] There are two sealing plates 6, both of which are connected to the U-shaped plate 2 and the mounting plate 5. One of the sealing plates 6 is a profile structure with a curled edge on one side, and the other sealing plate 6 is provided with a mounting hole for connecting and fixing the drain pipe 4. There are four drain pipes 4 and they are located at the rear of the U-shaped plate 2.

[0035] The two sealing plates 6 are used to fill the remaining parts after the transition seat 3, the U-shaped plate 2 and the mounting plate 5 are welded together, so as to completely isolate the interior of the driver's cab from the outside, ensure the sealing of the interior of the driver's cab and prevent rainwater from entering the driver's cab.

[0036] The drain pipe 4 is used for draining water from the rear of the whistle installation structure, draining water onto the roof of the passenger compartment, and finally draining water under the vehicle along the outer surface of the side wall.

[0037] The front inspection door 1 and the rear inspection door 7 are connected to the vehicle body by bolts and fixed.

[0038] The front inspection door 1 is consistent with the arc shape of the driver's cab head cover. The front inspection door 1 is made of an aluminum plate with many oblong holes for sound transmission. The front inspection door 1 is connected to the transition seat 3 around a circle by countersunk hexagon socket bolts. Opening the front inspection door 1 can be used to clean impurities in the U-shaped plate 2.

[0039] The rear inspection door 7 is consistent with the arc shape of the cab hood, and is made of an aluminum plate. The circumference of the rear inspection door 7 and the vehicle body skin are connected by countersunk hexagon socket bolts. Opening the rear inspection door 7 can be used to replace the whistle.

[0040] The contact surfaces of the front inspection door 1 and the rear inspection door 7 connected with the vehicle body fasteners are coated with dissimilar metal insulating paint, and the installation of the adjustment pad requires spraying of dissimilar metal insulating paint.
