[0034] The vehicle body structure includes the floor and other structures, including but not limited to doors and sheet metal. The body structure is the main supporting and load-bearing structure of the vehicle, playing a major role in the vehicle's stability and safety.

[0035] However, existing vehicle structures may have insufficient strength at the connection between the floor and door hinges during manufacturing, causing abnormal noises between the door hinges and the floor, and potentially affecting the vehicle's safety performance.

[0036] To solve the above technical problems, refer to Figures 1 to 3 As shown, this application provides a vehicle body structure, including a base plate 100, a connecting plate 200, and a reinforcing plate 300. The connecting plate 200 is connected to the base plate 100. The reinforcing plate 300 is stacked with the connecting plate 200 and connected to the connecting plate 200. The side of the connecting plate 200 away from the reinforcing plate 300 is connected to the base plate 100, and the side of the reinforcing plate 300 away from the base plate 100 is connected to the connecting plate 200. A first reinforcing rib 320 is connected to the base plate 100 and is disposed in the circumferential direction of the connecting portion 310. The first reinforcing rib 320 includes staggered first protrusions 321 and first recesses 322, and adjacent first protrusions 321 and first recesses 322 are connected to each other.

[0037] The base plate 100 is the main load-bearing and supporting structure of the vehicle body. The connecting plate 200 is used to connect the door structure, mainly connecting the door hinges. The connecting plate 200 is located between the reinforcing plate 300 and the base plate 100. The overlapping arrangement of the reinforcing plate 300 and the connecting plate 200 increases the connection area. The reinforcing plate 300 is also provided with a first reinforcing rib 320 to enhance the structural rigidity of the connecting plate 200. The first reinforcing rib 320, through its staggered first protrusions 321 and first recesses 322, can increase the compressive strength of the reinforcing plate 300 and reduce the risk of local buckling of the reinforcing plate 300, thereby increasing the connection strength between the door structure and the base plate 100 structure, reducing abnormal noise between the door hinges and the base plate 100, and improving the vehicle's safety performance.

[0038] In some embodiments, refer to Figure 1As shown, the vehicle body structure also includes a crossbeam 400. The crossbeam 400 is located circumferentially on the base plate 100 near the through rib 110 and extends to the connecting plate 200. In a first direction, the projected portions of the crossbeam 400 and the connecting plate 200 coincide. The crossbeam 400 is connected to the base plate 100 and perpendicular to the door structure. The crossbeam 400 can be configured as a straight beam or a curved beam depending on the vehicle interior structure. The projected portions of the crossbeam 400 and the connecting plate 200 coincide in the first direction, resulting in partial structural overlap between the connecting plate 200 and the crossbeam 400. Welding points can be provided at the overlap points of the crossbeam 400 and the connecting plate 200 to weld the connecting plate 200 and the crossbeam 400. The structural strength of the crossbeam 400 structure is greater than that of the base plate 100. By connecting a portion of the connecting plate 200 to the crossbeam 400, the connection strength of the connecting plate 200 can be further increased. Furthermore, the width at which the projections of the crossbeam 400 and the connecting plate 200 overlap in the first direction is between 40 mm and 55 mm.

[0039] In some embodiments, the floor 100 is a sheet metal structure disposed close to the chassis on the vehicle, which can be used to support the vehicle body seats, etc., and forms a passenger compartment with sheet metal parts such as doors inside the vehicle.

[0040] In some embodiments, refer to Figure 1 and Figure 2 As shown, the connecting plate 200 includes a second reinforcing rib extending along a second direction. The second reinforcing rib includes staggered second protrusions 250 and second recesses 260, with adjacent second protrusions 250 and second recesses 260 interconnected. The base plate 100 includes a through rib 110 extending along a second direction. The through rib 110 includes staggered third protrusions 111 and third recesses 112, with the third protrusions 111 and third recesses 112 interconnected. The second protrusions 250 and second recesses 260 on the second reinforcing rib are formed by processes such as stamping, and the third protrusions 111 and third recesses 112 on the through rib 110 are formed by processes such as stamping. The second reinforcing rib strengthens the connecting plate 200, and the through rib 110 strengthens the connection strength of the base plate 100. This also increases the connection strength between the connecting plate 200 and the base plate 100, thereby enhancing the overall vehicle body structure.

[0041] Specifically, the through rib 110 includes three third recesses 112 and third protrusions 111, with the height difference between the third recesses 112 and the third protrusions 111 ranging from 8 mm to 10 mm. The second reinforcing rib includes three second recesses 260 and second protrusions 250, with the height between the second recesses 260 and the second protrusions 250 ranging from 5 mm to 7 mm. The second recesses 260 and the third recesses 112 are spaced apart, with the spacing between the second recesses 260 and the third recesses 112 ranging from 2.8 mm to 3.2 mm.

[0042] In some embodiments, refer to Figure 1 and Figure 2 As shown, the second recess 260 is located within the third recess 112, and the second protrusion 250 is located on the third protrusion 111. The reinforcing plate 300 and the base plate 100 are connected to each other through the second protrusion 250 and the third protrusion 111. Multiple second welding points are provided on the second protrusion 250, and the connecting plate 200 and the base plate 100 are connected to each other by welding at these second welding points.

[0043] In some embodiments, refer to Figure 2 and Figure 4 As shown, the first recess 322 is recessed towards the side opposite to the connecting plate 200, and the surface of the first protrusion 321 is connected to the connecting plate 200. Multiple first welding points 323 are provided between the connecting plate 200 and the first protrusion 321, and the connecting plate 200 and the first protrusion 321 are welded together at the first welding points 323. Specifically, the first reinforcing rib 320 includes three first protrusions 321 and two first recesses 322, which can be configured according to actual conditions. Furthermore, the height difference between the first protrusion 321 and the second protrusion 250 of the reinforcing plate 300 is between 5mm and 7mm. The second recess 260 has a trapezoidal structure, which facilitates stamping.

[0044] In some embodiments, refer to Figure 3 and Figure 4 As shown, the first reinforcing rib 320 includes three first protrusions 321 and three first recesses, with the height difference between the first protrusions 321 and the first recesses 322 being between 5 mm and 7 mm. Welding points may also be provided on the first protrusions 321 to weld the connecting plate 200 and the reinforcing plate 300 together.

[0045] In some embodiments, the connecting plate 200 and the reinforcing plate 300 are provided with welding points on the connecting portion 310, and the connecting plate 200 and the reinforcing plate 300 are welded together through the welding points.

[0046] In some embodiments, refer to Figure 2 and Figure 5As shown, the connecting plate 200 has a first mounting hole 210, and the reinforcing plate 300 has a second mounting hole 330. The second mounting hole 330 and the first mounting hole 210 are coaxially arranged. The first mounting hole 210 and the second mounting hole 330 can be used to install the door hinge. When the door hinge is installed on the connecting plate, it is locked and fixed by inserting bolts into the door hinge, the first mounting hole 210 and the second mounting hole 330, thereby installing the hinge in the first mounting hole 210 and the second mounting hole 330.

[0047] In some embodiments, refer to Figure 5 As shown, the diameter of the first mounting hole 210 is larger than the diameter of the second mounting hole 330, and a stepped surface is formed between the first mounting hole 210 and the second mounting hole 330. The stepped surface facilitates the alignment of the first mounting hole 210 and the second mounting hole 330, making it easier to observe during installation.

[0048] In some embodiments, refer to Figure 5 As shown, one side of the connecting plate 200 extends away from the reinforcing plate 300 to form a flange 220, and the other side of the connecting plate 200 has a limiting part 230 in the same direction away from the reinforcing plate 300. The flange 220 and the limiting part 230 are located circumferentially around the first mounting hole 210. The flange 220 and the limiting part 230 are formed by stamping, bending, and other processes on the connecting plate 200, and the flange 220 also has rounded corners. When the bolt is inserted into the first mounting hole 210 and the second mounting hole 330, the nut is located in the limiting area between this side and the limiting part 230, thus limiting the nut. Furthermore, the connecting plate 200 is provided with a mounting part for mounting a hinge. The first mounting hole 210 is provided on the mounting part, which protrudes to one side of the connecting plate 200. The height of the folded edge 220 is between 5mm and 7mm. The height of the limiting part 230 is higher than the height of the folded edge 220. The protrusion height of the limiting part 230 is between 10mm and 20mm.

[0049] In some embodiments, refer to Figure 5 As shown, the connecting plate 200 includes a first clearance hole 240, and the reinforcing plate 300 is provided with a second clearance hole 340. The projected area of ​​the second clearance hole 340 in a first direction is at least equal to the projected area of ​​the first clearance hole 240. The first clearance hole 240 and the second clearance hole 340 are used to avoid part of the hinge structure, thereby allowing the hinge to rotate when the door is opened and closed. When the hinge structure extends into the first clearance hole 240, the second clearance hole 340 will not obstruct the hinge structure.

[0050] In some embodiments, refer to Figure 6 and Figure 7As shown, the vehicle body structure also includes a side panel assembly 500, which includes an inner panel 510 and a side reinforcing plate 520 stacked together. A connecting plate 200 extends away from the bottom plate 100 and connects to the side panel assembly 500. The connecting plate 200 is located on the side of the inner panel 510 away from the side reinforcing plate 520. The side panel assembly 500 includes sheet metal parts located outside the A-pillar, B-pillar, and C-pillar. The side panel assembly 500 can cover the vehicle body surface, increasing the structure of the vehicle body and making the vehicle body more aesthetically pleasing. The inner panel 510 and the side reinforcing plate 520 of the side panel assembly 500 have better structural strength, which can increase the rigidity of the side of the vehicle body. There is a gap between the inner panel 510 and the side reinforcing plate 520, which forms an energy-absorbing cavity, which can play an energy-absorbing role in the event of a vehicle collision. The connecting plate 200 is connected to the inner plate 510 of the side plate assembly 500. A welding point is provided between the inner plate 510 and the connecting plate 200 to weld the inner plate 510 and the connecting plate 200 together. Furthermore, a welding point can also be provided between the inner plate 510 and the side reinforcing plate 520 to weld the side reinforcing plate 520 and the connecting plate 200 together.

[0051] In some embodiments, refer to Figure 8 and Figure 9 As shown, the vehicle body structure also includes a wheel cover assembly 600, which is located below the base plate 100. The wheel cover assembly 600 forms a cavity 610, which is used to prevent wheel hubs from being damaged.

[0052] In some embodiments, the vehicle body structure includes, but is not limited to, a floor plate 100, a crossbeam 400, a connecting plate 200, a reinforcing plate 300, a side plate assembly 500, and a wheel arch assembly 600. The floor plate 100, connecting plate 200, and crossbeam 400 are interconnected and disposed on surfaces in a first direction. The connecting plate 200 connects to the side plate assembly 500, which extends at an angle to the first direction.

[0054] In some embodiments, the base plate 100, crossbeam 400, connecting plate 200, reinforcing plate 300, side plate assembly 500, and wheel cover plate assembly 600 can be welded by processes such as gas flame, electric arc, laser, electron beam, friction, and ultrasonic.

[0055] In this application, the first reinforcing rib 320 of the reinforcing plate 300, through staggered first protrusions 321 and first recesses 322, can increase the compressive strength of the reinforcing plate 300 and reduce the risk of local buckling of the reinforcing plate 300, thereby increasing the connection strength between the door structure and the floor 100 structure. The second reinforcing rib of the connecting plate 200 includes staggered second protrusions 250 and second recesses 260, with adjacent second protrusions 250 and second recesses 260 interconnected. The through rib 110 of the floor 100 includes staggered third protrusions 111 and third recesses 112, with the third protrusions 111 and third recesses 112 interconnected. The second reinforcing rib can strengthen the strength of the connecting plate 200, and the through rib 110 can strengthen the connection strength of the floor 100, and also increase the connection strength between the connecting plate 200 and the floor 100, thereby increasing the overall vehicle body structure. This reduces abnormal noise between the door hinges and the floor 100, increasing the vehicle's safety performance.

[0056] This application also provides a vehicle, including a body structure, wherein the floor plate 100 of the body structure is the main load-bearing and supporting structure of the vehicle body structure. A connecting plate 200 is used to connect the door structure, mainly connecting the hinges of the door structure. The connecting plate 200 is disposed between the reinforcing plate 300 and the floor plate 100. The overlapping arrangement of the reinforcing plate 300 and the connecting plate 200 increases the connection area. A first reinforcing rib 320 is also provided on the reinforcing plate 300 to enhance the structural rigidity of the connecting plate 200. The first reinforcing rib 320, through its staggered first protrusions 321 and first recesses 322, can increase the compressive strength of the reinforcing plate 300 and reduce the risk of local buckling of the reinforcing plate 300, thereby increasing the connection strength between the door structure and the floor plate 100 structure, reducing abnormal noise between the door hinges and the floor plate 100, and increasing the vehicle's safety performance.
