Technical Field
[0001] The utility model relates to the technical field of rail vehicle manufacturing, in particular to a storage floor step used in a driver's cab of a rail vehicle. Background Art
[0002] In rail vehicles such as EMUs, especially China Standard EMUs, a floor step structure of a certain height is provided under the driver's seat in the driver's cab according to ergonomic design to provide the driver with a wider field of vision, and the appearance and structure of the floor step will be adjusted due to the footrest under the driver's console and the opening and closing structure of the left and right cabinets. Therefore, the floor step needs to be adjustable when designed and ensure that it is firmly, flatly and beautifully installed with all parts under the driver's console, so as to reduce the current vehicle research and matching process as much as possible.
[0003] On the other hand, in order to deal with emergencies, the driver's cab needs to be equipped with emergency equipment such as escape ladders. However, the space in the driver's cab is relatively small, and setting up a storage cabinet specifically for the escape ladder will take up a certain amount of space.
[0004] Therefore, in order to correct the above-mentioned defect, we propose a storage floor step for a rail vehicle driver's cab. Utility Model Content
