The invention provides a self-dumping car side door opening and closing mechanism, and relates to the technical field of self-dumping cars, the self-dumping car side door opening and closing mechanism comprises a first connecting rod mechanism, the first connecting rod mechanism comprises a first connecting rod, a second connecting rod and a third connecting rod of which one ends are hinged together, and the other end of the first connecting rod is hinged to a first hinge of a first side door of a carriage; the other end of the second connecting rod is hinged to a bottom beam, and the other end of the third connecting rod is hinged to a bottom frame of a carriage. The first connecting rod mechanism is used for achieving transmission between the compartment and the first side door, so that the first side door is driven to be opened when the compartment turns over towards the side where the first side door is located. The opening and closing mechanism of the whole first side door is composed of a plurality of connecting rods and is simple in structure and easy to assemble. And the rod piece is light in self weight and easy to produce and manufacture, the self weight of the door opening and closing mechanism of the automatic dumping car can be effectively reduced, and manufacturing and maintenance cost is reduced.
