[0037] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0039] The seat mounting points, seat belts, and other installation structures are located on the vehicle floor, which also bears the stress on both the seats and seat belts. However, because there is no strong reinforcing beam in the middle of the floor, the thin, low-strength sheet metal results in insufficient strength and rigidity of the installation structure. In the event of a collision, the rear seat mounting structure and seat belts will generate inward pulling forces, causing the mounting structure to deform and shift due to these forces, thus affecting vehicle safety.

[0040] This application provides a vehicle body. Figure 1 This is a three-dimensional structural diagram of a vehicle body according to an exemplary embodiment of this application. Figure 2 This is a three-dimensional structural diagram of a vehicle body and seat assembly according to an exemplary embodiment of this application, such as... Figure 1 , Figure 2 As shown, Figure 1 , Figure 2 The dashed double-headed arrows represent the longitudinal direction of the vehicle body, and the dotted double-headed arrows represent the transverse direction. Vehicle body 1 includes a seat crossbeam 14, a floor assembly 12, a reinforcing structure 13, and a pair of wheel arch 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 both the first floor crossbeam 124 and the floor body 121. The two ends of the seat crossbeam 14 in the transverse direction, and the two ends of the first floor crossbeam 124 and the second floor crossbeam 123 in the transverse direction, are connected to the wheel arch structures 11. The reinforcing structure 13 is fixedly connected to the second floor crossbeam 123, the seat crossbeam 14, and the first seat mounting plate 122, forming a reinforcing framework.

[0041] The first seat mounting plate 122 can be located in the middle area of ​​the floor to secure structural components such as seats and seat belts. The aforementioned seat crossbeam 14, first floor crossbeam 124, and second floor crossbeam 123 can refer to crossbeam structures extending in the width direction of the vehicle body 1. The first floor crossbeam 124 and second floor crossbeam 123 can be located at different positions on the vehicle body 1 in the length direction and height direction to provide support for the floor. For example, the first floor crossbeam 124 can be a lower floor crossbeam, and the second floor crossbeam 123 can be an upper floor crossbeam. The first floor crossbeam 124 can be located in front of the second floor crossbeam 123 in the length direction of the vehicle body 1, and the first floor crossbeam 124 can be located below the second floor crossbeam 123 in the height direction of the vehicle body 1.

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

[0043] In some embodiments, such as Figure 3 As shown, Figure 3 In the diagram, a dashed double-headed arrow represents the longitudinal direction of the vehicle body, while a dotted double-headed arrow represents the lateral direction. Figure 3 The dashed box can represent multiple reinforcing frames. The seat crossbeam 14 includes a first central section spaced apart from both ends of the seat crossbeam 14 in the transverse direction. The second floor crossbeam 123 includes a second central section spaced apart from both ends of the second floor crossbeam 123 in the transverse direction. The reinforcing structure 13 includes a reinforcing body 131 and a sidewall 132 bent relative to the reinforcing body 131. The first end 1311 of the reinforcing body 131 is fixedly connected to the second central section. The sidewall 132 is fixedly connected to the first central section to form multiple reinforcing frames with the seat crossbeam 14, the second floor crossbeam 123, and a pair of wheel arch structures 11. The seat crossbeam 14 connects to the wheel arch structures 11 on both sides. The reinforcing structure 13, which is fixed to the first central section of the seat crossbeam 14 and the second central section of the second floor crossbeam 123, forms multiple reinforcing frames. The force transmission and torsional resistance of the frame structure of the reinforcing frame improves the stability and support strength of the reinforcing structure 13.

[0044] In the above embodiments, such as Figure 4 As shown, the side wall 132 may be provided with a slot 1321, and the first middle section is snapped and fixed in 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 or other methods, and this application does not limit this.

[0045] The reinforcing body 131 may have side walls 132 that are bent relative to the reinforcing body 131 at both ends in the horizontal direction. The first middle section is fixed by the side walls 132 at both ends of the reinforcing body 131, which can improve the support stability of the seat beam 14.

[0046] Furthermore, the aforementioned sidewall 132 may have at least one hollowed-out area 1322 to reduce material usage and overall weight while ensuring the supporting strength of the sidewall 132. For example, the sidewall 132 may have two hollowed-out areas 1322, which are spaced apart in different areas of the sidewall 132 to avoid affecting the strength of the sidewall 132.

[0047] In the above embodiments, the sidewalls 132 at both ends of the reinforcing body 131 in the lateral direction can have the same structure to improve processing convenience. Alternatively, the sidewalls 132 at both ends can have different structures to adapt to different spatial layouts and improve the flexibility of the body 1 component and other vehicle components.

[0048] In some embodiments, such as Figure 4 , Figure 5 As shown, Figure 4 A double-headed dashed arrow can represent a line connecting the third and fourth ends, or a line connecting the third and fifth ends. Figure 5 A solid double-headed arrow represents the direction of force, a dashed double-headed arrow represents the longitudinal direction of the vehicle body, and a dotted-dashed double-headed arrow represents the transverse direction of the vehicle body. The reinforcing body 131 may 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 central section, a fourth end connected to the first end 1311, and a fifth end connected to the second end 1312. The lines connecting the third and fourth ends and the third and fifth ends form an angle. The side wall 132 provides support for the first end 1311 and the second end 1312 of the reinforcing structure 13. The aforementioned angle provides reliable support, preventing the reinforcing structure 13 from warping or deforming along the length of the vehicle body 1 due to force transmission from the first and second ends 1311 and 1312.

[0049] In some embodiments, the reinforcing structure 13 may include a frame structure, which includes a first end 1311 and a second end 1312 disposed opposite to each other. 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 structure to the second floor beam 123 and the first seat mounting plate 122, the supporting strength of the reinforcing structure 13 between the second floor beam 123 and the first seat mounting plate 122 is improved, thereby enhancing the reliability of the support.

[0050] In the above embodiments, the reinforcing structure 13 may further include two support segments 133 disposed within the frame structure. The support segments 133 connect the first end 1311 and the second end 1312, and the two support segments 133 are arranged crosswise. The two crosswise support segments 133 within the frame structure of the reinforcing structure 13 form a cross-force transmission scheme, improving the support effect on the first seat mounting plate 122. Furthermore, the supporting force of the reinforcing structure 13 forms an upper and lower 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 beam 123 by two first connectors 15, and the second end 1312 is fixedly connected to the first seat mounting plate 122 by two second connectors 17. The first connectors 15 and the second connectors 17 are located on the extension line of the support section 133. The above structure forms a mutually supporting force transmission path at the four connection points corresponding to the first seat mounting plate 122 and the second floor beam 123, improving the support effect on the first seat mounting plate 122. The first connectors 15 and the second connectors 17 can be threaded connectors.

[0052] In some embodiments, such as Figure 1 , Figure 6 As shown, Figure 6 The double-dotted arrow in the middle can represent the height direction of the vehicle body 1. The vehicle body 1 may also include a seat belt mounting component 16, which is fixedly assembled to the first seat mounting plate 122. The first seat mounting plate 122 is fixed to the floor body 121 and the first floor crossbeam 124 respectively. The floor cannot be used as a load-bearing component. Therefore, the first seat mounting plate 122 forms a cantilever structure without the reinforcing structure 13. By supporting and fixing the first seat mounting plate 122 with the reinforcing structure 13, the structural strength of the first seat mounting plate 122 and the structural strength of the seat belt mounting component 16 set on the first seat mounting plate 122 are improved.

[0053] The first floor beam 124 can be welded to the first seat mounting plate 122, providing tension on the first seat mounting plate 122 from below the floor to resist the tension of the seat and seat belt.

[0054] In some embodiments, such as Figure 1 , Figure 7As shown, the vehicle body 1 may further include a second seat mounting plate 125 and a third seat mounting plate 126. The second seat mounting plate 125 and the third seat mounting plate 126 are fixed to the floor body 121. Laterally, the second seat mounting plate 125 and the third seat mounting plate 126 are located on both sides of the first seat mounting plate 122, and are respectively fixedly connected to the wheel arch 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, improving the stability and reliability of the seat assembly 2 installation. One end of the seat crossbeam 14 of the aforementioned vehicle body 1 can be connected to the second seat mounting plate 125, and the other end of the seat crossbeam 14 can be connected to the third seat mounting plate 126. Furthermore, one end of the aforementioned second floor crossbeam 123 can be connected to the second seat mounting plate 125, and the other end of the second floor crossbeam 123 can be connected to the third seat mounting plate 126. The connection between the aforementioned seat crossbeam 14, second floor crossbeam 123, wheel arch structure 11 and second seat mounting plate 125 and third seat mounting plate 126 can be welding.

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

[0056] This application further provides a vehicle, which includes the aforementioned vehicle body 1.

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

[0058] The aforementioned vehicles may be electric vehicles, gasoline vehicles, or hybrid vehicles, and may be used in home settings, public transportation, etc. This application does not impose any restrictions on this.

[0059] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
