The invention discloses a folding mechanism, a car coupler and a railway vehicle. The folding mechanism comprises a first rotating piece, a second rotating piece and a locking unit, the first rotatingpiece is provided with a locking groove, the locking groove is positioned at one end of the first rotating piece, one end of the second rotating piece is hinged with one end of the first rotating piece, the locking unit is fixed on the second rotating piece, the locking unit comprises a first locking piece and a first elastic piece, the first locking piece is hinged with the second rotating piece, the first locking piece is connected with the locking groove in a matched mode, one end of the first elastic piece is fixed to the second rotating piece, and the other end of the first elastic pieceis fixedly connected with the first locking piece, wherein when the first locking piece overcomes the elastic force of the first elastic piece to rotate and is disengaged from the locking groove, relative rotation between the first rotating piece and the second rotating piece is unlocked. The railway vehicle comprises the car coupler, and the car coupler comprises the folding mechanism. In the car coupler coupling process, the efficiency of adjusting a car coupler buffer and a coupling device is improved.
