The invention provides an automobile frame structure applied to the technical field of automobile chassis. The front ends of a front cross beam (1) and two longitudinal beams (2) of the automobile frame structure are fixedly connected, a plurality of convex strips (5) arranged around longitudinal beam bodies for a circle are arranged on the longitudinal beam bodies (3) of the longitudinal beams (2), a plurality of concave grooves (6) corresponding to the positions of the convex strips (5) one to one are formed in the inner walls of longitudinal beam sleeves (4), one end of each longitudinal beam sleeve (4) is arranged on the corresponding longitudinal beam body (3) in a sleeving mode, the other ends of the longitudinal beam sleeves (4) are connected with the front cross beam (1), and the convex strips (5) are embedded into the concave grooves (6) respectively. According to the automobile frame structure, when a common collision happens to an automobile, the front cross beam can effectively absorb impact force generated by the collision, and injuries of the collision to a driver and passengers in the automobile are avoided. When a serious collision happens to the automobile, the function of collapsing and buffering is achieved, the safety of the driver and the passengers is effectively protected, and the safety performance of the whole automobile is improved.
