The drainage door sill 131 is located at the bottom of the car body and has a lower sliding groove 1311 extending along the longitudinal direction. The lower sliding rail 12 is located in the lower sliding groove 1311 and can slide along the lower sliding groove 1311. The lower sliding groove 1311 is used to collect rainwater on the outer wall of the door leaf 11 and can drain the rainwater to the outside of the car body.

[0016] The lower sliding rail 12 is fixed at the bottom of the door leaf 11 and can slide along the lower sliding groove 1311. The lower sliding rail 12 is located in the lower sliding groove 1311 and can slide along the lower sliding groove 1311 to guide the longitudinal sliding of the door leaf 11. The drainage door sill 131 is located at the bottom of the car body and is fixed with the car body bolster 300 and the door sill, preferably in detachable fixed connection. The drainage door sill 131 has a lower sliding groove 1311 extending along the longitudinal direction. The two ends of the lower sliding groove 1311 penetrate through the drainage door sill 131 to facilitate the sliding of the lower sliding rail 12 therein. The lower sliding groove 1311 is used to collect rainwater on the outer wall of the door leaf 11 and can drain the rainwater to the outside of the car body. In this way, the drainage effect of the car body 1000 can be ensured, and the erosion of the car body internal components by rainwater can be reduced.

[0017] Compared with the prior art, the vehicle compartment 1000 and the rail vehicle provided in the embodiments have the following technical effects: In the present application, the sliding door assembly 100 is arranged on the side wall 200 of the vehicle compartment body, and the sliding door assembly 100 includes a door leaf 11, a lower sliding rail 12, and a sliding door drainage device 13. The drainage threshold 131 of the sliding door drainage device 13 is arranged at the bottom of the vehicle compartment body and has a lower sliding groove 1311 extending in the longitudinal direction. The lower sliding rail 12 is located in the lower sliding groove 1311 and slides along the lower sliding groove 1311. The lower sliding groove 1311 is used to collect the rainwater falling from the outer wall of the door leaf 11 and drain the rainwater to the outside of the vehicle compartment body. In this way, the waterproof and anticorrosion performance of the vehicle compartment 1000 at the door is improved, the rainwater is prevented from entering the inside of the vehicle compartment 1000 and corroding the floor 400 or other internal structures, and the waterproof and drainage effects of the whole vehicle are improved.

[0018] As shown in the drawings, Figures 9-10 In a specific embodiment, the drainage threshold 131 includes a first cavity 1312 and a second cavity 1313.

Each drainage hole 13131 penetrates the second cavity 1313 to the first cavity 1312 at one end in the transverse direction and communicates with the outside at the other end in the transverse direction. The rainwater is guided from the lower sliding groove 1311 of the first cavity 1312 to the outside, so as to quickly drain the accumulated water from the lower sliding groove 1311, improve the drainage speed of the accumulated water, prevent the rainwater from accumulating in the vehicle body for a long time, and reduce the corrosion of the vehicle body. The drainage hole 13131 is preferably a square drainage hole 13131, such as a rectangular drainage hole 13131. The bottom surface of the drainage hole 13131 is flush with the bottom wall of the second cavity 1313 and the bottom wall of the first cavity 1312, so as to drain all the accumulated water in the first cavity 1312 and the second cavity 1313 and reduce the accumulation. Further, the bottom wall of the first cavity 1312 and the bottom wall of the second cavity 1313 are arranged to be inclined from the inside to the outside in the transverse direction, which is more convenient for the rainwater to flow out of the first cavity 1312 and the second cavity 1313 to the outside.

[0020] As shown in the drawings, Figures 11-12As shown, specifically, the sliding door drainage device 13 further comprises a drainage collection groove 132 having an opening at the top and extending longitudinally, a longitudinal end of the drainage collection groove 132 extending below the lower chute 1311, and a longitudinal other end of the drainage collection groove 132 extending to correspond to the door leaf 11 in the open state. The bottom of the drainage collection groove 132 is provided with a plurality of drainage pipes 1323 for communicating with the outside to drain rainwater.

Specifically, rainwater within the lower trough 1311 is discharged to the exterior of the vehicle body through the drainage holes 13131 in the transverse second cavity 1313 and the longitudinally disposed second trough 1322. By discharging rainwater through corresponding drainage structures disposed transversely and longitudinally, the drainage effect is further optimized, the time rainwater remains in the vehicle body is reduced, and the drainage rate is increased. Several drainage holes 13131 are provided at the bottom of the second trough 1322, each connected to a drainage pipe 1323 to drain rainwater within the second trough 1322 to the exterior of the vehicle body. The drainage pipes 1323 are evenly distributed longitudinally along the second trough 1322 to further enhance drainage.

[0024] Preferably, the inner side wall of the two lateral sides of the first trough 1321 is higher than the outer side wall, thereby blocking rainwater close to the inner side, preventing rainwater from entering the body pillow beam 300 or the interior of the body, and reducing corrosion to the interior of the body.
