[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 7 As shown, a car body sill beam structure is installed on the side of the vehicle body to enhance side impact resistance and facilitate the installation of a foot pedal. It includes a sill beam assembly 1, which includes an outer sill plate 9. The outer sill plate 9 is the side of the vehicle body that contacts the door. A B-pillar 12 is fixedly connected to one side of the outer sill plate 9. The B-pillar 12 is a side structure of the vehicle body, increasing structural safety. On the same side of the B-pillar 12, a front section 2, a middle section 3, and a rear section 4 of the inner sill plate are sequentially fixedly connected to the outer sill plate 9. The front section 2, the middle section 3, and the rear section 4 of the inner sill plate are connected by welding, increasing integrity and strength. A pedal mounting bracket 5 is fixedly connected to one side of the front section 2 of the inner sill plate. Two pedal mounting brackets 6 are fixedly connected to the middle section 3 of the inner sill plate on the same side as the front section 2. A pedal mounting bracket 6 is fixedly connected to the rear section 4 of the inner sill plate on the same side as the middle section of the inner sill plate. A suspension reinforcement bracket 8 is fixedly connected to the rear section 4 of the inner sill plate near the B-pillar 12. A pedal mounting bracket 7 is fixedly connected to the rear section 4 of the inner sill plate on one side. The aforementioned pedal mounting brackets 5, 6, and 7 facilitate the installation of the pedals, making it convenient for people to get in and out of the vehicle. Two side collision reinforcement brackets 11 are fixedly connected to the outer sill plate 9 near the B-pillar 12 to increase the structural strength of this area and improve safety. A B-pillar reinforcement plate 10, fixedly connected to the outer sill plate 9, is located between the sill beam assembly 1 and the B-pillar 12 to increase structural strength.

[0024] The side collision reinforcing support 11 does not contact the front section 2, the middle section 3 and the rear section 4 of the inner rocker panel, and the advantage of the design is that when the outer rocker panel 9 is subjected to external force, the side collision reinforcing support 11 collapses to absorb energy, thereby reducing the internal injury. The suspension reinforcing support 8 is provided with an opening in the middle, which reduces the weight of the vehicle body without affecting the structural strength. The pedal mounting bracket one 5 is fixed to the front section 2 of the inner rocker panel by welding square nuts, and the pedal mounting bracket two 6 is fixed to the middle section 3 and the rear section 4 of the inner rocker panel by welding square nuts, and the square nuts are welded to strengthen the structural strength of the area. The outer rocker panel 9, the front section 2, the middle section 3 and the rear section 4 of the inner rocker panel are made by one-piece stamping, and the stamping method can save cost, has better integrity and more stable structure.

[0025] Finally, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
