[0039] The seat mounting points, seat belts and other mounting structures are arranged on the vehicle body floor, which also bears the forces of the seats and seat belts. However, because there is no strong reinforcement beam in the middle of the floor, the low-strength thin plate leads to insufficient strength and rigidity of the mounting structure. In the event of a collision, the rear seat mounting structure, seat belts, etc. will generate a pulling force into the vehicle, causing the mounting structure to deform and displace due to the pulling force, affecting the safety of the vehicle.

[0040] The present application provides a vehicle body. Figure 1 is a schematic diagram of a three-dimensional structure of a vehicle body in an exemplary embodiment of the present application, Figure 2 FIG. 1 is a schematic diagram of a three-dimensional structure of a vehicle body and a vehicle seat in an exemplary embodiment of the present application. Figure 1 , Figure 2 As shown, Figure 1 , Figure 2 The dashed double-headed arrow in the figure may represent the longitudinal direction of the vehicle body, and the dot-dash double-headed arrow may represent the transverse direction of the vehicle body. The vehicle body 1 includes a seat crossbeam 14, a floor assembly 12, a reinforcement structure 13, and a pair of wheel housing structures 11. The floor assembly 12 includes a floor body 121, a first seat mounting plate 122, a first floor crossbeam 124, and a second floor crossbeam 123. The first seat mounting plate 122 is fixedly connected to the first floor crossbeam 124 and the floor body 121, respectively. Both ends of the seat crossbeam 14 in the transverse direction, and both ends of the first floor crossbeam 124 and the second floor crossbeam 123 in the transverse direction are connected to the wheel housing structure 11, respectively. The reinforcement structure 13 is fixedly connected to the second floor crossbeam 123, the seat crossbeam 14, and the first seat mounting plate 122, respectively, so that the reinforcement structure 13, the second floor crossbeam 123, the seat crossbeam 14, and the first seat mounting plate 122 form a reinforcement structure.

[0041] The first seat mounting plate 122 may be located in the middle area of ​​the floor to fix the seats, safety belts and other structural components. The seat cross beam 14, the first floor cross beam 124 and the second floor cross beam 123 may refer to cross beam structures extending in the width direction of the vehicle body 1. The first floor cross beam 124 and the second floor cross beam 123 may be located at different positions of the vehicle body 1 in the length direction and the height direction of the vehicle body 1 to form support for the floor. For example, the first floor cross beam 124 may be a lower floor cross beam, the second floor cross beam 123 may be an upper floor cross beam, the first floor cross beam 124 may be located in front of the second floor cross beam 123 in the length direction of the vehicle body 1, and the first floor cross beam 124 may be located below the second floor cross beam 123 in the height direction of the vehicle body 1.

[0042] In the above embodiment, the reinforcing structure 13 is fixedly connected to the second floor cross beam 123, the seat cross beam 14 and the first seat mounting plate 122 respectively. The reinforcing structure 13, the second floor cross beam 123, the seat cross beam 14 and the first seat mounting plate 122 form a reinforcing structure, which helps to strengthen the structural strength and stability of the floor and the mounting structure arranged on the floor, thereby improving the safety of vehicle use.

[0043] In some embodiments, Figure 3 As shown, Figure 3 The dotted double-headed arrow in the figure can represent the longitudinal direction of the vehicle body, and the dotted double-headed arrow can represent the lateral direction of the vehicle body. Figure 3 The middle dotted frame may represent a plurality of reinforcement frames. The seat cross beam 14 includes a first middle section spaced apart from both ends of the seat cross beam 14 in the transverse direction. The second floor cross beam 123 includes a second middle section spaced apart from both ends of the second floor cross beam 123 in the transverse direction. The reinforcement structure 13 includes a reinforcement body 131 and a side wall 132 bent relative to the reinforcement body 131. The first end 1311 of the reinforcement body 131 is fixedly connected to the second middle section. The side wall 132 is fixedly connected to the first middle section to form a plurality of reinforcement frames with the seat cross beam 14, the second floor cross beam 123 and a pair of wheel housing structures 11. The seat cross beam 14 is connected to the wheel housing structures 11 on both sides. The reinforcement structure 13 fixed to the first middle section of the seat cross beam 14 and the second middle section of the second floor cross beam 123 forms a plurality of reinforcement frames. The force transmission and torsion resistance of the frame structure of the reinforcement frame are used to improve the stability and support strength of the reinforcement structure 13.

[0044] In the above embodiment, if Figure 4 As shown, the side wall 132 may be provided with a slot 1321, and the first middle section is fixedly connected to the slot 1321 to improve assembly convenience and reliability. Alternatively, the side wall 132 and the first middle section may be fixedly connected by welding, threaded connection, etc., which is not limited in the present application.

[0045] The two ends of the reinforcing body 131 in the transverse direction may be respectively provided with side walls 132 bent relative to the reinforcing body 131 , and the first middle section may be fixed by the side walls 132 at both ends of the reinforcing body 131 , thereby improving the support stability of the seat cross beam 14 .

[0046] Furthermore, the side wall 132 may be provided with at least one hollow area 1322 to reduce the amount of material used and the overall weight while ensuring the supporting strength of the side wall 132. For example, the side wall 132 may be provided with two hollow areas 1322, and the hollow areas 1322 are arranged at intervals in different areas of the side wall 132 to avoid affecting the strength of the side wall 132.

[0047] In the above embodiment, the side walls 132 at both ends of the reinforcing body 131 in the transverse direction may have the same structure to improve processing convenience. The side walls 132 at both ends may also have different structures to adapt to different spatial layouts and improve the flexibility of the arrangement of the body 1 components and other vehicle components.

[0048] In some embodiments, Figure 4 , Figure 5 As shown, Figure 4 The dotted double-headed arrow in the middle can represent the line connecting the third end and the fourth end, or the line connecting the third end and the fifth end. Figure 5 The solid double-sided arrow can represent the force direction, the dashed double-sided arrow can represent the longitudinal direction of the vehicle body, and the dot-dash double-sided arrow can represent the transverse direction of the vehicle body. The reinforcement body 131 can include a first end 1311 fixedly connected to the second floor crossbeam 123 and a second end 1312 fixedly connected to the first seat mounting plate 122. The side wall 132 includes a third end connected to the first middle section, a fourth end connected to the first end 1311, and a fifth end connected to the second end 1312. The line connecting the third end and the fourth end and the line connecting the third end and the fifth end form an inclination angle. The first end 1311 and the second end 1312 of the reinforcement structure 13 can be supported by the side wall 132. The above-mentioned inclination angle can form a reliable support to prevent the reinforcement structure 13 from warping and deforming in the length direction of the vehicle body 1 due to the force transmitted by the first end 1311 and the second end 1312.

[0049] In some embodiments, the reinforcement structure 13 may include a frame-type structure, which includes a first end 1311 and a second end 1312 that are relatively arranged, the first end 1311 is fixedly connected to the second floor beam 123, and the second end 1312 is fixedly connected to the first seat mounting plate 122. By fixing the two ends of the frame-type structure to the second floor beam 123 and the first seat mounting plate 122, the supporting strength of the reinforcement structure 13 between the second floor beam 123 and the first seat mounting plate 122 is improved, thereby improving the supporting reliability.

[0050] In the above embodiment, the reinforcement structure 13 may further include two support segments 133 disposed in the frame structure, the support segment 133 connecting the first end 1311 and the second end 1312, and the two support segments 133 are cross-arranged. Through the two support segments 133 cross-arranged in the frame structure of the reinforcement structure 13, a cross force transmission scheme is formed, which improves the support effect on the first seat mounting plate 122. And the support force of the above reinforcement structure 13 forms an up-and-down support relationship in the height direction of the vehicle body 1, which can better resist the tension of the seat belt and the seat.

[0051] In the above embodiment, the first end 1311 is fixedly connected to the second floor crossbeam 123 through two first connectors 15, and the second end 1312 is fixedly connected to the first seat mounting plate 122 through two second connectors 17. The first connector 15 and the second connector 17 are arranged on the extension line of the support section 133. The above structure is arranged at four connection points corresponding to the first seat mounting plate 122 and the second floor crossbeam 123 to form a mutually supporting force transmission path, thereby improving the supporting effect on the first seat mounting plate 122. The above first connector 15 and the second connector 17 may be threaded connectors.

[0052] In some embodiments, Figure 1 , Figure 6 As shown, Figure 6 The double-dotted arrow in the middle may represent the height direction of the vehicle body 1, and the vehicle body 1 may further include a seat belt mounting member 16, which is fixedly assembled to the first seat mounting plate 122. The first seat mounting plate 122 is respectively fixed to the floor body 121 and the first floor cross beam 124, and the floor cannot be used as a force-bearing component, so the first seat mounting plate 122 forms a cantilever structure without the reinforcement structure 13. The reinforcement structure 13 supports and fixes the first seat mounting plate 122, thereby improving the structural strength of the first seat mounting plate 122 and the structural strength of the seat belt mounting member 16 provided on the first seat mounting plate 122.

[0053] The first floor cross beam 124 may be connected to the first seat mounting plate 122 by welding, and provide a pulling force to the first seat mounting plate 122 under the floor to resist the pulling force of the seat and the safety belt.

[0054] In some embodiments, Figure 1 , Figure 7As shown, the vehicle body 1 may also include a second seat mounting plate 125 and a third seat mounting plate 126, which are fixed to the floor body 121. In the horizontal direction, the second seat mounting plate 125 and the third seat mounting plate 126 are respectively located on both sides of the first seat mounting plate 122, and the second seat mounting plate 125 and the third seat mounting plate 126 are respectively fixedly connected to the wheel cover structure 11. The seat assembly 2 can be installed through the first seat mounting plate 122, the second seat mounting plate 125 and the third seat mounting plate 126, and the reliability of the installation of the seat assembly 2 is improved. One end of the seat cross beam 14 of the vehicle body 1 can be connected to the second seat mounting plate 125, and the other end of the seat cross beam 14 can be connected to the third seat mounting plate 126. Further, one end of the second floor cross beam 123 can be connected to the second seat mounting plate 125, and the other end of the second floor cross beam 123 can be connected to the third seat mounting plate 126. The seat cross beam 14, the second floor cross beam 123, the wheel cover structure 11, the second seat mounting plate 125 and the third seat mounting plate 126 may be connected by welding.

[0055] In the embodiments of the present application, the seat assembly 2 may refer to a front row seat or a rear row seat, and the present application does not limit this.

[0056] The present application further provides a vehicle, which includes the vehicle body 1 described above.

[0057] Since the reinforcing structure 13 of the vehicle body 1 is fixedly connected to the second floor cross beam 123, the seat cross beam 14 and the first seat mounting plate 122 respectively, the reinforcing structure 13, the second floor cross beam 123, the seat cross beam 14 and the first seat mounting plate 122 form a reinforcing structure, which helps to strengthen the structural strength and stability of the floor and the mounting structure arranged on the floor, thereby improving the safety of vehicle use.

[0058] The above-mentioned vehicles can be electric vehicles, fuel vehicles, or hybrid vehicles. The above-mentioned vehicles can be used in household scenarios, public transportation, etc., and this application does not limit this.
