Fig. 1-5 show a sill structure of a car door and a car, wherein the car has an entrance and an exit, and the sill structure is installed at the bottom of the entrance and the exit. A hanger rail is mounted at an upper position of the car. The car door is mounted on the hanger rail so that the car door can open and close the entrance in a side-sliding manner. The sill structure comprises a chute body 3 and a matching component. The chute body 3 is mounted on the bottom of the car 1. The runner body 3 has a designed length. The top surface of the chute body 3 forms a sill surface. The sill surface is flush with the inner bottom surface of the car 1. The inside processing of spout body 3 has smooth chamber 31, and this smooth chamber 31 extends along the length direction of spout body 3, processes on the bottom surface of spout body 3 to have the notch with smooth chamber 31 intercommunication.

The above-mentioned mating assembly comprises a slider 7, a side plate 6 and a connecting piece. The slider 7 may be made of a plastic or rubber material. The slider 7 is adapted to the slide chamber 31 and can freely enter and exit the slide chamber 3 through the notch. In this embodiment, after the slider 7 is installed in the sliding cavity 31, the slider 7 is in clearance fit with the inner wall of the sliding cavity 31, so that the slider 7 can move back and forth along the length direction of the sliding cavity 31. The side plate 6 is mounted on the car door 2 by means of bolts so that the side plate 6 can be detached from the car door 2. The side plate 6 is located on the side of the chute body 3 away from the car 1. The lower end of the side plate 6 extends in the lower direction and forms a free end. The first end of the connecting piece is fixedly connected with the sliding block 7 in a detachable mode, and the second end of the connecting piece is fixedly connected with the side plate 6 in a detachable mode. By removing the slider 7, the slider 7 can be moved out of the slide chamber 31 and the connecting piece can be removed separately from the side plate 6.

In the present embodiment, the connecting member is preferably a bolt 8. The bolt 8 is a standard fitting in the prior art. The side plate 6 and the slider 7 are respectively provided with a mounting hole 61. When the slider 7 is fitted into the slide cavity 31, the mounting holes on the side plate 6 and the mounting holes 61 on the slider 7 correspond, and the central axes of the mounting holes 61 of both extend in the horizontal direction. The bolt 8 may be inserted into the mounting holes 61 of both in the horizontal direction. A first nut 81 and two second nuts 82 are screwed to the bolt 8. A first locking position is formed between the first nut 81 and the head of the bolt 8. Two second nuts 82 form a second locking position. One of the side plate 6 and the slider 7 is locked at a first locking position, and the other is locked at a second locking position. The side plate 6 and the sliding block 7 are connected together by the locking of the first nut 81 and the second nut 82. The bolt 8 and the slider 6 are removed by loosening the first nut 81 and the second nut 82.

In this embodiment, the chute body 3 includes a first bending member 4 and a second bending member 5. The first bending part 4 and the second bending part 5 are formed through a sheet metal bending process.
