The invention discloses a front end frame structure of an automobile. The front end frame structure comprises a frame body, wherein the frame body comprises an upper cross beam, a lower cross beam, aleft longitudinal beam, a right longitudinal beam and a herringbone beam; the ends of the left longitudinal beam, the upper cross beam, the right longitudinal beam and the lower cross beam are sequentially connected to form a square frame-shaped structure, an installing support is arranged on the outer side of the left longitudinal beam and on the outer side of the right longitudinal beam respectively, the herringbone beam comprises two inclined supporting beams symmetrically arranged in the square frame structure, and two ends of each inclined supporting beam are connected to the upper crossbeam and the lower cross beam. The front end frame structure of the automobile is of an integral plastic formed structure, is formed by integral thermoplastic injection molding, is light in weight, low in cost and good in integral performance, and the integral forming structure is adopted, so that the integral performance of the structure is improved; meanwhile, the supporting beams and the herringbone beam are arranged in the frame structure, so that the integral structural strength and rigidity performance of the structure are improved.
