According to the technical scheme provided by the embodiment and the attached drawings, the bottom cabin plate component and the side cabin plate component can be independently applied or combined by a person skilled in the art.

In this embodiment, the length direction of the bogie is the same as the traveling direction, that is: longitudinal direction (e.g., X direction in fig. 1). The width direction of the bogie is perpendicular to the driving direction, namely: the lateral direction (e.g., the Y direction in fig. 1). The height direction of the bogie is also: the vertical direction (e.g., the Z direction in fig. 1).

Fig. 1 is a schematic structural diagram of a self-protection bogie according to an embodiment of the present invention. As shown in fig. 1, the present embodiment provides a self-protecting bogie including: the bogie comprises a bogie 10 and a bogie cabin 20, wherein the bogie cabin 20 is enclosed at the bottom and the side of the bogie 10. Namely: the bogie hull has a bottom structure and side structures that enclose the bogie 10.
