The invention discloses a front longitudinal beam assembly structure of an automobile. The front longitudinal beam assembly structure comprises a front floor and a front floor upper longitudinal beam fixedly arranged at the upper part of the front floor; a front longitudinal beam auxiliary beam is further fixedly arranged at the upper part of the front floor; one end of the front longitudinal beam auxiliary beam is fixedly connected with the front floor upper longitudinal beam in a lapping manner to integrally form a herringbone beam structure; further, the two sides of the front floor upper longitudinal beam downwards form first turned-over edges, and the front floor upper longitudinal beam is welded and fixedly connected to the front floor through the first turned-over edges; one end of the front floor upper longitudinal beam upwards warps and adopts an arc-shaped beam structure; one end of the front longitudinal beam auxiliary beam adopts an occlusion structure and is occluded onto the arc-shaped beam structure of the front floor upper longitudinal beam; the front longitudinal beam auxiliary beam is welded and fixedly connected with the front floor upper longitudinal beam through the occlusion structure. The front longitudinal beam assembly structure is simple, the lower part space of the front floor is saved, the space is provided for arrangement of a chassis, a force transmission structure is optimized, the weight of NVH parts at the upper part of the front floor is reduced and the cost is reduced.
