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.

    本公开涉及一种前纵梁的吸能结构、前纵梁、前机舱骨架总成及车辆,所述前纵梁包括纵梁本体(1),所述吸能结构(2)用于设置于所述纵梁本体(1)并包括多个吸能格(21),所述多个吸能格(21)构造为在纵向上成行和垂向上成列布置的网格状结构,所述吸能格(21)包括能够在纵向上溃缩吸能的沿垂向延伸布置的第一吸能板(211),多个同行布置的所述第一吸能板(211)的壁厚,沿由前向后的方向上逐渐增大,和/或,沿横向延伸布置的第二吸能板(212),多个同行布置的所述第二吸能板(212)的壁厚,沿由前向后的方向上逐渐增大。该吸能结构能够保证自身稳定的碰撞溃缩,且能够保证自身的吸能效率。
