摘要： A battery case is provided, including a plurality of side plates. A first side plate has the largest area among the plurality of side plates, and at least one first side plate includes a first portion and a second portion. The first portion is a curved surface concave toward inside of the battery case. A three-dimensional coordinate system is established in a first direction, a second direction, and a third direction, and the second direction is perpendicular to the first side plate. A curvature of the first portion is less than a curvature of an ellipsoid, the curvature of the ellipsoid is obtained from an ellipsoid function, and the ellipsoid function is: ((x−a)/i)2+((y−b)/j)2+((z−c)/k)2=1, where, a, b, c, i, j, and k are determined according to coordinates of at least four points that are different from each other, and x, y, and z are coordinates of the three directions of the ellipsoid function.

摘要： The present disclosure discloses a driver console and a rail vehicle including the driver console. The driver console includes: a console body, a display screen, a control console, and a mechanical mechanism. The display screen is movable between a first position and a second position relative to the console body. The control console is movable between a third position and a fourth position relative to the console body. When the display screen is at the first position and the control console is at the third position, the driver console is in a manned state. When the display screen is at the second position and the control console is at the fourth position, the driver console is in an unmanned state. According to the driver console of the present disclosure, the manned state and the unmanned state can be effectively compatible with both the manned state and the unmanned state.
