The left rear end of the upper front floor front crossbeam 1 is fixedly connected to an upper left crossbeam 4, and the right rear end of the upper front floor front crossbeam 1 is fixedly installed with an upper right crossbeam 5. The lower end of the upper front floor front crossbeam 1 is installed with a lower front floor front crossbeam 6.

A reinforcing component 9 is installed between the upper left crossbeam 4, the upper right crossbeam 5 and the lower left crossbeam 10, the lower right crossbeam 11.
[0025] The lower sides of the upper front floor front crossbeam 1, the upper left longitudinal beam 2, the upper right longitudinal beam 3, the upper left crossbeam 4, and the upper right crossbeam 5 are in contact with and fixedly connected to the upper sides of the lower front floor front crossbeam, the lower left longitudinal beam 7, the lower right longitudinal beam 8, the lower left crossbeam 10, and the lower right crossbeam 11.
[0026] One side of the upper end of the upper front floor front crossbeam 1 is fixedly connected to a front apron beam 12, and a reinforcing member 13 is fixedly installed at the rear side of the front apron beam 12. The lower side of the reinforcing member 13 is fixedly connected to the other side of the upper end of the upper front floor front crossbeam 1.
[0027] By arranging the reinforcing member 13 to connect the upper front floor front crossbeam 1 and the front apron beam 12, the connection between the upper front floor front crossbeam 1, the reinforcing member 13 and the front apron beam 12 can be made more reliable, the structural strength of the skeleton can be improved, and the overall performance of the vehicle with the skeleton can be improved.
[0028] As Figures 3-4 As shown in the figure, the reinforcing component includes a middle crossbeam 91. The left and right ends of the middle crossbeam 91 are fixedly connected to the inner front ends of the upper left crossbeam 4, the upper right crossbeam 5, the lower left crossbeam 10, and the lower right crossbeam 11. A rear crossbeam 92 is installed behind the middle crossbeam 91. Reinforcing members 93 are symmetrically installed on the left and right sides of the middle crossbeam 91 and the rear crossbeam 92. Support diagonal beams 94 are symmetrically and fixedly connected to both sides of the front end of the middle crossbeam 91. Reinforcing blocks one 95, reinforcing blocks two 97, and reinforcing blocks three 99 are respectively fixedly connected to the lower ends of the upper front floor front crossbeam 1, the upper left longitudinal beam 2, the upper right longitudinal beam 3, the upper left crossbeam 4, and the upper right crossbeam 5. Grooves one 96, grooves two 98, and grooves three 910 are respectively formed inside the upper ends of the lower front floor front crossbeam 6, the lower left longitudinal beam 7, the lower right longitudinal beam 8, the lower left crossbeam 10, and the lower right crossbeam 11.
[0029] The left and right ends of the rear crossbeam 92 are fixedly connected to the inner rear ends of the upper left crossbeam 4, the upper right crossbeam 5, the lower left crossbeam 10, and the lower right crossbeam 11.
[0030] The reinforcement 93 is triangular in shape, and the left and right sides of the middle cross beam 91 and the rear cross beam 92 are fixedly connected to one side of the reinforcement 93, while the other side of the reinforcement 93 is fixedly connected to the inner sides of the upper left cross beam 4, the upper right cross beam 5 and the lower left cross beam 10, and the lower right cross beam 11.
[0031] The top of the supporting oblique beam 94 is fixedly connected to the inner sides of the front ends of the upper left cross beam 4 , the upper right cross beam 5 and the lower left cross beam 10 , and the lower right cross beam 11 .
[0032] The positions of the three groups of reinforcement blocks correspond to the positions of the three groups of grooves. Reinforcement block one 95, reinforcement block two 97 and reinforcement block three 99 are respectively embedded in the inside of groove one 96, groove two 98 and groove three 910.
[0033] By supporting the oblique beam 94 and the reinforcing member 93, the strength of the front floor frame is reinforced, so that the front floor has a stronger anti-collision performance during use, and the quality of the front floor frame structure is improved.
[0034] The following specifically describes the working principle of the front floor frame reinforcement structure.
[0035] like Figures 1-4 As shown, when the front floor frame reinforcement structure is in use, when it is hit, the two groups of left longitudinal beams and the two groups of left longitudinal beams can transmit the collision force to the upper front floor front cross beam 1 and the lower front floor front cross beam 6, and at the same time, through the front enclosure beam 12, the front enclosure beam 12 can transmit the collision force to the upper left cross beam 4, the upper right cross beam 5 and the lower left cross beam 10, and the lower right cross beam 11 through the force transmission beam, so that the two groups of left longitudinal beams and the two groups of right longitudinal beams can smoothly transmit the collision force to the front floor frame assembly, thereby improving the force transmission performance of the body frame, reducing the shrinkage of the frame assembly, and improving the positive impact of the vehicle. The three groups of reinforcement blocks are all stuck in the three groups of grooves, so that the inner sides of the upper groups of cross beams and longitudinal beams and the lower groups of cross beams and longitudinal beams are welded and fixed by supporting oblique beams 94, middle cross beams 91 and rear cross beams 92, which can further enhance the strength of the front floor frame. In addition, the fixing places of the middle cross beam 91, the rear cross beam 92 and the inner sides of the two groups of left longitudinal beams and the two groups of right longitudinal beams are all provided with triangular reinforcement members 93, which strengthens the strength of the front floor frame, so that the front floor has stronger anti-collision performance during use and improves the quality of the front floor frame structure.
[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
