The invention provides a synchronous pre-tightening pull rope door closing mechanism for a vertical lifting automobile tailboard, and belongs to the technical field of automobile accessories. The movable pulley assembly is installed on the driving shaft of the lifting driver used for driving the tail plate to ascend and descend, meanwhile, the fixed pulley assembly is installed on the compartment or the shell of the lifting driver, and the pull rope used for pulling the tail plate to turn over and connecting the tail plate and the winding device firstly bypasses the movable pulley assembly and then bypasses the fixed pulley assembly. The stay cord and the movable pulley assembly are matched to form the structure consistent with the structure formed by the chain wheel on the driving shaft of the lifting driver and the driving chain used for being matched with the chain wheel and connected with the lifting guide rail, and therefore it is guaranteed that the lifting stroke of the tail plate can be consistent wit
