The invention relates to a front floor assembly collision structure, and relates to the technical field of automobile design and manufacturing. The front floor assembly collision structure comprises a middle channel front section and a middle channel rear section, the two sides of the middle channel rear section are welded to a front floor, the outer side of the front floor is fixedly connected with a threshold edge beam assembly, and the Y direction of a seat front cross beam and the Y direction of a seat rear cross beam penetrate through the middle channel rear section and are connected with the front floor. The two ends of the seat front cross beam and the two ends of the seat rear cross beam are connected with the doorsill edge beam assembly. The rear portion of the middle channel front section is in lap joint with the front portion of the middle channel rear section, the rear portion of the middle channel front section is welded to the two sides of the middle channel rear section, and the two sides of the middle channel front section are welded to the front floor. A welding edge is arranged at the rear end of the middle channel front section, and the welding edge is in lap joint with the seat rear cross beam and is welded to the upper surface of the seat rear cross beam. According to the front floor assembly collision structure, the smoothness of load transmission of side collision and direct collision can be effectively improved, the collision structure is optimized, and light weight is achieved.
