Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
An apron assembly according to an embodiment of the invention is described below with reference to fig. 1-11. The skirt assembly may be applied to a rail vehicle 100 such as a tram. In the following description of the present application, an example in which the apron assembly is applied to a rail vehicle 100 such as a railroad car is explained. Of course, those skilled in the art will appreciate that the rail vehicle 100 may also be a subway, a light rail, or the like.
As shown in fig. 1 to 11, a skirt assembly according to an embodiment of the present invention is adapted to be provided to a vehicle body 1, the vehicle body 1 including a base frame 11 and a mounting plate 2, the mounting plate 2 being provided below the base frame 11, and the mounting plate 2 defining an opening with the base frame 11. Wherein the skirt assembly comprises a base frame 11, a mounting plate 2 and at least one moving skirt 3.
Specifically, the moving skirt 3 is provided between the base frame 11 and the mounting plate 2, and the moving skirt 3 is movable between a first position (shown in fig. 1 and 2) in which the moving skirt 3 closes the opening and a second position (shown in fig. 5) in which the moving skirt 3 moves as a whole in a direction away from the base frame 11 and the mounting plate 2 to open the opening when the moving skirt 3 moves from the first position to the second position. For example, in the example of fig. 1-5, the mounting plate 2 is located below the base frame 11 and spaced up and down from the base frame 11, an opening is defined between an outer end of the base frame 11 and an outer end of the mounting plate 2, and the moving skirt 3 is horizontally movably mounted at the opening. Here, it should be noted that the direction "outer" may be understood as a direction away from the longitudinal center plane of the chassis 11, and the opposite direction is defined as "inner", i.e., a direction toward the longitudinal center plane of the chassis 11.
When the skirt panel assembly is applied to a rail vehicle 100, such as a tram, the moving skirt panel 3 is in the first position during driving to ensure safety during driving. When the rail vehicle 100, such as a tram, needs to be overhauled or checked, a maintenance person can pull the moving skirt board 3 outwards to move the whole moving skirt board 3 from the first position to the second position, and in the process, the maintenance person can observe surrounding obstacles while opening the door, so that safety accidents are avoided. When whole removal skirtboard 3 removed to the second position, the opening exposes, and maintainer can overhaul or the point is examined rail vehicle 100 such as tram through the opening, owing to remove skirtboard 3 and chassis 11 and mounting panel 2 and all separate the certain distance this moment, provides spacious space for follow-up maintenance or point is examined, makes the maintenance more convenient, has improved rail vehicle 100 such as tram's maintenance or point efficiency of examining.
