The invention discloses a front-end structure of an automobile body front longitudinal beam. The front-end structure comprises front longitudinal beam main bodies and energy absorption boxes, wherein the energy absorption box is fixed at the front end of the front longitudinal beam main body; a group of collapse grooves are formed in each of the front end of the front longitudinal beam main body and the energy absorption box in the length direction; the collapse grooves in the adjacent surfaces of the front end of the front longitudinal beam main body and the energy absorption box are staggered from one another; a gap is formed between the end portion of each collapse groove in each surface and the edge of the surface. The collapse grooves are formed in the front longitudinal beam main body and the energy absorption box and the collapse grooves in the adjacent surfaces are staggered from one another, and therefore, the energy absorption and force transfer effects of the front longitudinal beams can be well balanced and the collision performance of the entire automobile is improved; besides, the front-end structure of the automobile body front longitudinal beam is simple, and low in machining cost.
