The invention relates to the technical field of automobile accessories, in particular to a supporting rod assembly, a tail door assembly and an automobile, and the supporting rod assembly is simple in structure, low in cost and capable of hovering at any position. The supporting rod assembly comprises a sleeve and a supporting rod, wherein one axial end is provided with an opening; the telescopic piece comprises a cylinder barrel and a piston rod, at least partial structures of the cylinder barrel and the piston rod penetrate through the sleeve through the opening, and the piston rod is connected with the sleeve; the elastic piece is arranged on at least part of the structure, penetrating through the sleeve, of the cylinder barrel and is slidably connected with the sleeve in the axial direction; concave parts and convex parts which are matched with each other are arranged between the matching surfaces of the elastic piece and the sleeve, and one of the concave parts and the convex parts is arranged on the inner wall of the sleeve and sequentially arranged in the axial direction; the other one is arranged on the outer wall of the elastic piece; the elastic piece has a locking state for limiting the sleeve to slide in the axial direction. In the locking state, at least part of the structure of the convex part is embedded in the concave part; when the piston rod extends or retracts, the piston rod is suitable for driving the sleeve to slide in the axial direction and releasing the locking state of the elastic piece.
