ALUMINUM ALLOY CARGO COMPARTMENT PLATE, PREPARATION METHOD, CARGO COMPARTMENT, VARIABLE-CROSS-SECTION CARRIAGE, AND TRUCK

An aluminum alloy cargo compartment plate (10A), which is configured to enclose a cargo compartment. The thickness of the aluminum alloy cargo compartment plate is gradually changed in a vertical direction of the cargo compartment. By designing the aluminum alloy cargo compartment plate to be gradually changed in the vertical direction, when the cargo compartment enclosed by the aluminum alloy cargo compartment plate is used, the thickness of each position of aluminum alloy cargo compartment side plates can be correspondingly set according to the stress condition of the cargo compartment during an actual use process. Further disclosed are a preparation method of the aluminum alloy cargo compartment plate, a cargo compartment, a carriage, and a truck.
