The invention relates to an energy absorption structure of a front longitudinal beam, the front longitudinal beam, a front cabin framework assembly and a vehicle, the front longitudinal beam comprises a longitudinal beam body (1), the energy absorption structure (2) is used for being arranged on the longitudinal beam body (1) and comprises a plurality of energy absorption lattices (21), and the energy absorption lattices (21) are constructed into latticed structures which are arranged in rows in the longitudinal direction and arranged in columns in the vertical direction. Each energy absorption grid (21) comprises first energy absorption plates (211) which can collapse and absorb energy in the longitudinal direction and extend in the vertical direction, the wall thicknesses of the multiple first energy absorption plates (211) arranged in the same row are gradually increased in the direction from front to back, and/or second energy absorption plates (212) arranged in the transverse direction are gradually increased in the direction from front to back, and the wall thicknesses of the multiple second energy absorption plates (212) arranged in the same row are gradually increased in the direction from front to back. And the width is gradually increased in the direction from front to back. According to the energy absorption structure, stable collision collapse of the energy absorption structure can be guaranteed, and the energy absorption efficiency of the energy absorption structure can be guaranteed.
