Wherein, the barrier body 210 between the lower part and the side of the barrier is used to receive the liquid that enters from the cover plate vent hole 110 to block the liquid from entering the barrier body 210 away from the cover plate Side.

The ventilation structure of the embodiment of the present application includes a cover plate and a blocking member; wherein the cover plate has a cover plate vent, the blocking member is disposed on a side of the cover plate facing the vehicle body, and a lower portion of the blocking member Sealed and fixed with the cover plate under the cover plate vent hole, the side of the blocking member and the cover plate are sealed and fixed outside the side end of the cover plate vent hole; the lower part of the blocking member The main body of the barrier between the side and the side is used to receive the liquid entering from the vent hole of the cover plate, to block the liquid from entering the side of the main body of the barrier away from the cover plate, and then to block the liquid from entering the vehicle in vivo. Compared with the background art, the ventilation structure of the embodiment of the present application adds a blocking member, which blocks liquid entering from the vent holes of the cover plate from entering the side of the blocking member away from the cover plate, thereby blocking liquid from entering In the vehicle body, the liquid entering the ventilation structure is prevented from damaging the equipment in the train.

When the liquid entering from the vent hole of the cover plate increases, if the height of the liquid reaches the position of the vent hole of the cover plate, the vent hole of the cover plate can also play a role of discharging part of the liquid.

During the implementation, the waterproof level of the barrier reaches the international industrial waterproof rating standard IPX5.

In implementation, as shown in FIG. 3, a waterproof sealing strip 120 is provided on the inner edge of the cover plate, and the waterproof level of the waterproof sealing strip reaches the international industrial waterproof rating standard IPX5.

In implementation, as shown in FIG. 3, the barrier body 210 is recessed away from the cover plate 100, so that an accommodation gap is formed between the barrier body 210 and the cover plate 100;

Wherein, the accommodating gap is used for accommodating the liquid entering from the cover plate vent 110.

The existence of the accommodating gap indicates that the barrier body and the cover plate are not in close contact, that is, the ventilation structure can accommodate a certain amount of liquid, so that it can also be applied when the external environment of the train installed in the ventilation structure has more liquid .

In order to expel the liquid in the accommodating gap as soon as possible, in implementation, as shown in FIG. 3, the cover plate further includes a liquid outlet 130, and the position of the liquid outlet 130 is lower than the cover plate vent hole 110 The lower part of the blocking member and the cover plate are sealed and fixed under the liquid outlet 130, so that the liquid entering the accommodation gap is discharged from the liquid outlet.

The position of the liquid outlet is lower than the position of the vent hole of the cover plate, so that the liquid containing the gap can be discharged from the liquid outlet in time.

In order to avoid liquid in the accommodation gap. In implementation, as shown in FIG. 3, the upper edge of the lower closed end 221 of the barrier is flatter or higher than the lower edge of the liquid outlet 130; wherein, the lower closed end 221 of the barrier is the barrier The lower part of the piece is used to seal and fix the part under the liquid outlet;

With the lower inclined portion and the liquid outlet of the above structure, the liquid in the accommodating gap is discharged in time, and no liquid is stored in the accommodating gap.

In order to realize the exhaust of the gas generated by the equipment in the vehicle body, in implementation, the cover plate ventilation hole is located at the upper part of the cover plate;

4 is a partial enlarged view of FIG. 3, as shown in FIG. 4, the upper part of the barrier has a barrier ventilation hole 230, so that the gas generated by the equipment in the vehicle body passes through the barrier ventilation hole 230 and the The cover vent 110 is discharged.

In this way, the gas generated by the equipment in the vehicle body, especially the gas with a lower density than air, such as hydrogen gas, directly rises and is discharged through the barrier ventilation hole on the upper portion of the barrier and the cover panel ventilation hole. The situation as a ventilation structure using the embodiment of the present application is as follows:

The equipment in the car body generates hydrogen, and the lead-acid battery as a low-voltage power supply in the car body will inevitably release hydrogen gas during use. Due to the needs of the train function, the lead-acid battery needs to be arranged in the train car, so it is necessary to use the ventilation structure of the embodiment of the present application to exhaust hydrogen in time.

In order to prevent the liquid entering from the vent hole of the cover plate from entering the vehicle body through the vent hole of the blocking member. In implementation, as shown in FIG. 4, the position of the barrier vent 230 is higher than the position of the cover vent 110 to prevent liquid entering from the cover vent 110 from passing through the barrier vent 230 Into the car body.

In this way, it is avoided that the liquid entering from the vent hole of the cover plate enters the vehicle body through the vent hole of the blocking member, causing damage to the equipment in the train.

In implementation, as shown in FIG. 1, the upper end of the ventilation structure is also provided with a top vent 300 communicating with the accommodation gap, so that the gas generated by the equipment in the vehicle body passes through the barrier vent 230 and the top vent 300 are discharged.

The structure of the top vent can exhaust the gas generated by the equipment as much as possible, especially for the exhaust of less dense gas such as hydrogen.

In implementation, the blocking member ventilation holes are oblong holes arranged laterally;

Alternatively, there are a plurality of barrier ventilation holes, each of the barrier ventilation holes is arranged at equal intervals in the lateral direction, and the barrier ventilation holes are oblong holes.

In the implementation, as shown in FIGS. 2 and 3, the cover plate vent holes 110 are multiple and are inward-turning blinds; or they may be outward-turning blinds.

In implementation, as shown in FIG. 2, there are a plurality of liquid outlets 130, and the positions of the liquid outlets are highly consistent, and the liquid outlets are oblong holes.
