The above structure proposes a new technical solution to address the deficiencies in the prior art. In the structure of the present invention, the urban rail vehicle includes a door 26, a door carrier 12 of the door 26 is connected to the upper part of the door leaf 5, an arc-shaped sealing strip 15 is arranged on the side of the door carrier 12 close to the vehicle body 9, and a V-shaped boss 27 is arranged on the vehicle body 9 close to the door carrier 12. The vehicle body needs to be connected to the mechanism outer cover plate 2. When connected, the end bent hook strip 22 on the mechanism outer cover plate 2 is attached to the hook strip I 19 and wraps the spherical convex part 21, and the positioning strip 23 is inserted into the gap 25 between the hook strip I 19 and the hook strip II 20. The positioning strip 23 is attached to the lower surface of the hook strip I 19, and the sealing rubber 10 is attached to the lower surface of the mechanism outer cover plate 2. In this way, the hook strip 18 on the top of the vehicle body 9 and the bent hook strip 22 at the end of the mechanism cover plate 2 are completely fitted and concentric, and the mechanism cover plate 2 can rotate along the center line of the hook strip I19; and the connecting bracket 16 is riveted to the vehicle body 9, and the bottom of the mechanism cover plate 2 is connected to the connecting bracket 16 with screws to restrict the movement of the mechanism cover plate 2. After the vehicle body 9 and the mechanism cover plate 2 are connected, when it rains, a very small amount of water will flow out from the gap at the fitting place and flow into the hook strip I19 extending from the vehicle body 9. At this time, the sealing rubber 10 is installed on the hook strip I19 extending from the vehicle body 9. When the mechanism cover plate 2 is locked, the sealing rubber 10 and the mechanism cover plate 2 are completely fitted, and water will accumulate in the C-shaped groove. Referring to Figure 1, the hook-shaped strip I19 extending from the car body 9 is a segmented profile, which is disconnected at the gaps between the mechanism outer cover plate 2 and the end mask I, the mechanism outer cover plate I and the end mask II8, and the mechanism outer cover plate 2 and the mechanism outer cover plate II. The water accumulated in the hook-shaped strip I19 will be drained from the disconnected parts, which are not door openings, and can be directly discharged from the outside of the car. In this way, while solving the sealing problem, the drainage problem is effectively solved. The urban rail vehicle body sealing structure described in the present invention has a simple structure, improves the vehicle sealing performance while ensuring the vehicle appearance quality, safety, reliability, and comfort, and solves the drainage problem, effectively improving the performance of the rail vehicle.

The outer edge of the hook strip II 20 is clamped with a sealing rubber strip 10. In the above structure, when the mechanism cover plate 2 is connected to the vehicle body 9 through the connecting bracket 16, the hook strip 18 on the top of the vehicle body 9 and the bent hook strip 22 at the end of the mechanism cover plate 2 are completely in contact and concentric, forming a seal. At the same time, the sealing rubber 10 of the hook strip II 20 extending from the vehicle body is completely in contact with the lower surface of the mechanism cover plate, forming another seal. These two seals solve the problem of top sealing.

When the mechanism cover plate 2 is connected to the vehicle body 9 through the connecting bracket 16, the end bent hook strip 22 on the mechanism cover plate 2 is set to fit on the hook strip I 19 and wrap the spherical protrusion 21, and the positioning strip 23 is inserted into the gap 25 between the hook strip I 19 and the hook strip II 20. When the mechanism cover plate 2 is connected to the vehicle body 9 through the connecting bracket 16, the positioning strip 23 is set to fit on the lower surface of the hook strip I 19, and the sealing rubber 10 is set to fit on the lower surface of the mechanism cover plate 2.

The urban rail vehicle includes a door, a door carrier 12 of a door 26 connected to the upper part of a door leaf 5, a curved sealing strip 15 is arranged on the side of the door carrier 12 close to the vehicle body 9, and a V-shaped boss 27 is arranged on the vehicle body 9 close to the door carrier 12. Both side ends of the V-shaped boss 27 are disconnected structures. In the above structure, the curved sealing strip on the door carrier cooperates with the V-shaped boss on the vehicle body to solve the problem of sealing the side door area; the curved sealing strip is installed on the door carrier, and during the reciprocating movement of the door leaf, the moving curved sealing strip is always in contact with the V-shaped boss, and the V-shaped boss on the vehicle body is disconnected at the gap between the mechanism outer cover plate and the mask and the gap between the two mechanism outer cover plates 2, and the disconnected portion is used for drainage of the curved sealing strip 15. In this way, the arc-shaped sealing strip 15 is installed on the door frame 12. During the reciprocating movement of the door leaf 5, the moving arc-shaped sealing strip 15 is always in contact with the V-shaped boss on the vehicle body 9. When a very small amount of water splashes over the door leaf 5 outside the vehicle, it will flow into the V-shaped boss on the vehicle body 9 along the arc-shaped sealing strip 15. The V-shaped boss 27 extending from the vehicle body 9 is a segmented profile, which is disconnected at the gaps between the mechanism outer cover plate 2 and the end mask Ⅰ1, the mechanism outer cover plate Ⅱ7 and the end mask Ⅱ8, and the mechanism outer cover plate Ⅰ2 and the mechanism outer cover plate Ⅱ7.

The positioning strip fits on the lower surface of the hook-shaped strip I, and the sealing rubber fits on the lower surface of the mechanism outer cover plate. In this way, the hook-shaped strip on the top of the vehicle body and the end bent hook-shaped strip of the mechanism outer cover plate are completely fitted and concentric, and the mechanism outer cover plate can rotate along the center line of the hook-shaped strip I; the connecting bracket is riveted to the vehicle body, and the bottom of the mechanism outer cover plate is connected to the connecting bracket with screws to constrain the movement of the mechanism outer cover plate. After the car body is connected to the mechanism outer cover plate, when it rains, a very small amount of water will flow out from the gap at the joint and flow into the hook-shaped strip I extending from the car body. At this time, the sealing rubber is installed on the hook-shaped strip I extending from the car body. When the mechanism outer cover plate is locked, the sealing rubber and the mechanism outer cover plate are completely fitted, and water will accumulate in the C-shaped groove. Referring to Figure 1, the hook-shaped strip I extending from the car body is a segmented profile, which is disconnected at the gap between the mechanism outer cover plate and the end mask I, the mechanism outer cover plate I and the end mask II, and the mechanism outer cover plate and the mechanism outer cover plate II.
