The invention relates to a mounting and fixing structure of a car third-row seat. The mounting and fixing structure comprises a left longitudinal beam and a right longitudinal beam connected below a rear floor and is characterized in that a third-row seat left reinforcing longitudinal beam with an 'n'-shaped section is connected above the rear floor and corresponds to the left longitudinal beam; a third-row seat right reinforcing longitudinal beam with an 'n'-shaped section is connected above the rear floor and corresponds to the right longitudinal beam; a left mounting support of the third-row seat is connected to the front portion of the third-row seat left reinforcing longitudinal beam, and a right mounting support of the third-row seat is connected to the front portion of the third-row seat right reinforcing longitudinal beam; a third-row crossbeam component is connected between the upper surfaces of the middle portion of the third-row seat left reinforcing longitudinal beam and the third-row seat right reinforcing longitudinal beam. By the mounting and fixing structure, the strength and rigidity of the part, for mounting the third-row seat, of the rear floor can be increased evidently, the requirements for supporting the third-row seat and passengers are satisfied, and the overall NVH performance of a car body is improved.
