The invention discloses a front longitudinal beam energy absorption structure and a vehicle. The front longitudinal beam energy absorption structure comprises a front collision cross beam, an energy absorption box, a front longitudinal beam assembly, a cabin edge beam, a first metal plate, a second metal plate and a third metal plate, the front collision cross beam, the energy absorption box and the front longitudinal beam assembly are sequentially connected in the direction from front to back, and the cabin edge beam is arranged on the outer side of the front longitudinal beam assembly; one end of the first metal plate is fixedly connected with the external surface of the energy absorption box, and the other end is fixedly connected with the front end surface of the cabin edge beam; the second metal plate is longitudinally arranged, one end of the second metal plate is fixedly connected with the upper edge of the front part of the front longitudinal beam assembly, and the other end of the second metal plate is fixedly connected with the upper edge of the front part of the cabin edge beam; the third metal plate is longitudinally arranged below the second metal plate, one end of the third metal plate is fixedly connected with the outer side face of the front portion of the front longitudinal beam assembly, and the other end of the third metal plate is fixedly connected with the inner side face of the front portion of the cabin edge beam. The front longitudinal beam assembly, the cabin edge beam, the second metal plate and the third metal plate define a first energy absorption cavity. According to the front longitudinal beam energy absorption structure, the energy absorption effect of the front longitudinal beam assembly during offset collision can be improved.
