A wing opening van body comprises a bottom plate, a top plate, a side plate and openable wing plates which are arranged on both sides of the top plate. A switch device of the wing plates comprises an elastic mechanism and a manual mechanism. The elastic mechanism is arranged on the top of the van body and comprises an elastic element and an interlocking rod mechanism, when the wing plates are in closed state, the compressed elastic element generates upward thrust to the wing plates through the interlocking rod mechanism when the wing plates are opened; the manual mechanism is arranged on the outer surface of the end part of the van body and comprises a drive handle and a transmission rod mechanism, the transmission rod mechanism is equipped with a self-locking speed reducer, and the moment generated by the drive handle drives the wing plates to be opened, closed and suspended through the transmission rod mechanism. A transport vehicle and a container are provided with the wing opening van body. The wing opening van body overcomes the problem that bidirectional limitation and stable opening and closing can not be realized in the prior art, and ensures smooth and safe operation.
