The invention belongs to the technical field of automobile parts and provides a sub-frame structure. The sub-frame structure comprises an upper shell, a lower shell connected with the upper shell, and a sleeve, wherein the sleeve comprises an upper mounting section close to a frame and a lower mounting section far from the frame; one end, close to the frame, of the upper mounting section is fixedly connected to the upper shell; a first through hole is formed in the lower shell; one section, far from the frame, of the lower mounting section is inserted into the first through hole and is fixedly connected to the lower shell. According to the sub-frame structure, the outer wall of the sleeve is inserted into the first through hole of the lower shell; a connection position is changed from the end surface connection of the shell to the outer wall connection, so that two ends of the sleeve are respectively fixed with the upper shell and the lower shell, so that the release of a tightening torque caused by the connection of the sleeve after the sub-frame is connected with the frame can be avoided, and thus the connection stability between the sub-frame and the frame and the safety of an overall automobile can be improved.
