[0035] The present application provides a cargo box floor assembly, a cargo box assembly and a vehicle. The cargo box floor assembly, the cargo box assembly and the vehicle are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0036] refer to Figure 1 and Figure 2 An embodiment of the present application provides a cargo box floor assembly, including a cargo box flat bottom plate 20 and a reinforcement plate 30. The cargo box flat bottom plate 20 includes a front overlapping area 22 and a front weak area 21 for overlapping with the cargo box front panel 10. The front weak area 21 is connected to the front overlapping area 22 and is located in the end corner area of ​​the cargo box flat bottom plate 20 close to the cargo box front panel 10. The reinforcement plate 30 is fixedly connected to the cargo box flat bottom plate 20, and at least part of the structure of the reinforcement plate 30 is located in the front weak area 21.

[0037] It is easy to understand that the cargo box flat floor plate 20 is a flat plate without any geometric shape, and its own support stiffness is relatively low. Under external load excitation, the weak area of ​​the cargo box flat floor plate 20 is prone to large deformation and cracking, especially the above-mentioned front weak area 21, which is located in the end corner area of ​​the cargo box flat floor plate 20 close to the cargo box front wall plate 10, and is more susceptible to large torque. Therefore, the embodiment of the present application can enhance the structural strength of the cargo box flat floor plate 20 in this area by arranging a reinforcing plate 30 in the front weak area 21, thereby avoiding the front weak area 21 from cracking and other problems under external load excitation as much as possible, thereby improving the service life of the cargo box flat floor plate 20. The above-mentioned external load excitation can be the cargo load located on the cargo box flat floor plate 20, the acceleration response load when the vehicle is driving on a bumpy road, etc., but is not limited thereto.

[0038] It should be noted that Figure 1 The space enclosed by the middle dotted line 21 refers to the front weak area 21, and the space enclosed by the dotted line 22 refers to the front overlapping area 22, but the front weak area 21 and the front overlapping area 22 enclosed by the above dotted lines are only for illustration, and are not used to limit the specific spatial dimensions of the front overlapping area 22 and the front weak area 21. There are two front weak areas 21, which are respectively located in the left corner area and the right corner area of ​​the cargo box flat bottom plate 20 close to the cargo box front wall plate 10. In this embodiment, at least one of the two front weak areas 21 is provided with a reinforcing plate 30. In a preferred embodiment, both front weak areas 21 are provided with the above-mentioned reinforcing plates 30. However, for the sake of convenience of explanation, the following embodiment is only described by taking one front weak area 21 as an example, but those skilled in the art should understand that both front weak areas 21 are provided with reinforcing plates 30, which is also covered within the scope of protection of this application.

[0039] refer to Figure 3 Combined with Figure 2 In one embodiment, the reinforcing plate 30 includes an outer edge 31, which faces the outside of the cargo box flat bottom plate 20 and is flush with the side edge of the cargo box flat bottom plate 20. The projection of the outer edge 31 in the thickness direction of the reinforcing plate 30 falls on the side edge of the cargo box flat bottom plate 20. In other words, the outer edge 31 of the reinforcing plate 30 will not exceed the side edge of the cargo box flat bottom plate 20, so as to avoid excessive material of the reinforcing plate 30 overlapping other structures such as the side frame 52 of the cargo box.

[0040] In one embodiment, the thickness of the reinforcing plate 30 may be equal to the thickness of the cargo box flat floor 20 , but is not limited thereto.

[0041] In one embodiment, the reinforcing plate 30 further includes a mounting portion for fixedly connecting with the cargo box flat bottom plate 20, and the mounting portion is arranged away from the outer edge 31. By arranging the mounting portion at a position away from the outer edge 31, the outer edge 31 of the reinforcing plate 30 can have a certain movement tendency, which can alleviate the influence of external impact or pressure on the connection between the reinforcing plate 30 and the cargo box flat bottom plate 20, and improve the service life of the reinforcing plate 30. In some embodiments, the mounting portion can be a connection hole 37, a welding position, a riveting position, etc., but is not limited thereto.

[0042] In one embodiment, the mounting portion includes at least two connection holes 37, and the cargo box flat bottom plate 20 also includes connection matching holes corresponding to the connection holes 37, and the corresponding connection holes 37 and connection matching holes are used for bolts to pass through. The correspondence here means that the number and position of the connection matching holes correspond to the number and position of the connection holes 37. In this embodiment, the bolts can pass through the connection holes 37 and the connection matching holes to firmly connect the reinforcement plate 30 and the cargo box flat bottom plate 20. In addition, by providing two fewer connection holes 37 and connection matching holes, compared with one connection hole 37 and connection matching hole, this embodiment can effectively reduce stress concentration and make the overall stiffness of the reinforcement plate 30 more uniform.

[0043] refer to Figure 3 and Figure 4 In one embodiment, the front weak area 21 and the front overlap area 22 have an overlapping area at the joint, and the mounting portion is located in the overlapping area, which is used to be fixedly connected with the cargo box flat bottom plate 20 and the cargo box front wall plate 10. Specifically, the connection hole 37 of the reinforcing plate 30 can be located in the overlapping area, and the above-mentioned cargo box front wall plate 10 can be provided with a through hole corresponding to the connection hole 37. Bolts can pass through the connection hole 37, the connection adapter hole and the through hole to fix the reinforcing plate 30, the cargo box flat bottom plate 20 and the cargo box front wall plate 10 to compress the reinforcing plate 30.

[0044] In one embodiment, the reinforcing plate 30 further includes an inner edge located inside the outer edge 31, and the inner edge is provided with an arc-shaped inner edge 321 at the end corner of the reinforcing plate 30. The arc-shaped inner edge 321 can make the transition of the reinforcing plate 30 at the end corner smoother and reduce the problem of stress concentration.

[0045] In a further embodiment, the arc-shaped inner edge 321 is located at the end corner of the reinforcing plate 30 close to the center of the cargo box flat bottom plate 20, and the arc-shaped inner edge 321 is recessed toward the inside of the reinforcing plate 30. In this way, on the basis of being able to reduce stress concentration and enhance the strength of the front weak area 21, the material consumption of the reinforcing plate 30 can also be saved.

[0046] like Figure 3In the illustrated embodiment, the reinforcing plate 30 covers the entire front weak area 21. The reinforcing plate 30 is an asymmetric flat plate structure, including an outer edge 31, a front edge 33, a lower edge 34, and an inner edge. The front edge 33 and the lower edge 34 are respectively connected to the outer edge 31 and the inner edge. The inner edge includes an arc-shaped inner edge 321 and a linear inner edge 322. One end of the arc-shaped inner edge 321 is smoothly transitioned to the lower edge 34 through a first transition chamfer 35, and the other end is smoothly transitioned to the linear inner edge 322 through a second transition chamfer 36. The linear inner edge 322 is parallel to the outer edge 31, and the end of the linear inner edge 322 away from the arc-shaped inner edge 321 is connected to the front edge 33. Exemplarily, the length of the outer edge 31 can be 120 mm, the length of the front edge 33 is 170 mm, the length of the lower edge 34 is 65 mm, the length of the linear inner edge 322 is 40 mm. The arc-shaped inner edge 321 can be arc-shaped, and its radius of curvature can be 65 mm. Both the first transition chamfer 35 and the second transition chamfer 36 can be arc-shaped, and the radius of curvature of both can be 13 mm. However, it should be noted that the above dimensions are only a specific embodiment given in this embodiment for the convenience of those skilled in the art to understand, and this embodiment is not used to limit the present application. For example, in some other embodiments, the dimensions of each edge of the reinforcing plate 30 can be other values, and the arc-shaped inner edge 321 can be in the shape of an elliptical arc, a combination of an arc and an elliptical arc, etc.

[0047] Reference Figure 5 、 Figure 6 and Figure 7 and in combination with Figure 4 In one embodiment, the cargo box floor assembly further includes a plurality of cross beams 41. The plurality of cross beams 41 are fixedly connected to the bottom of the cargo box flat floor 20 and are spaced along the length direction of the cargo box flat floor 20 (i.e., the front-rear direction shown in Figure 4 and Figure 5 ). Each of the cross beams 41 includes a main body portion, and the main body portion has a reinforcing groove 411. The reinforcing groove 411 is recessed on the side背离 the cargo box flat floor 20. Both ends of the reinforcing groove 411 extend outwardly with connecting flanges 412, and the connecting flanges 412 are fixedly connected to the cargo box floor. In other words, the cross beam 41 with the above structure is generally in an inverted "U" shape, so that the supporting effect of the cross beam 41 is better. There is a large contact area between the connecting flange 412 and the cargo box flat floor 20, so that the supporting stiffness of the cross beam 41 to the cargo box flat floor 20 is also relatively gentle, and the load on the cargo box flat floor 20 is not easily concentrated and piled up.

[0048] The cross beam 41 and the cargo box flat bottom plate 20 may be fixed by welding. Specifically, welding points may be provided on the connecting flange 412, and the cross beam 41 is welded and fixed to the cargo box flat bottom plate 20 by welding, but the invention is not limited thereto. For example, in some other embodiments, the cross beam 41 and the cargo box flat bottom plate 20 may be connected by screwing, riveting, etc.

[0049] In one embodiment, the cross beam 41 is also fixedly connected to the side frame 52. Specifically, at the two end regions of the cross beam 41 in the length direction, the peripheral wall of the reinforcement groove 411 extends outward to form a frame connection portion 413, and the frame connection portion 413 is fixedly connected to the side frame 52 of the cargo box. Specifically, a welding spot may be provided on the frame connection portion 413, which is welded and fixed to the side frame 52. Figure 7 In the illustrated embodiment, two opposite side walls and a bottom wall of the reinforcement groove 411 both protrude outwardly with a frame connection portion 413 , and the frame connection portion 413 is a plate-like structure formed integrally with the reinforcement groove 411 , but is not limited thereto.

[0050] In one embodiment, the spacing between two adjacent beams 41 may be a preset value, wherein the preset value may be 300 mm, or may be 200 mm to 400 mm, that is, the spacing between two adjacent beams 41 may be 200 mm, 250 mm, 350 mm, 400 mm, etc. It should be noted that the preset value may be set according to the actual scenario, and this embodiment only provides some reference values ​​and ranges, and is not intended to limit the present application.

[0051] Continue to refer Figure 5 Combined with Figure 4 In one embodiment, the plurality of cross beams 41 further include a front cross beam 42, which is fixedly connected to the bottom of the cargo box flat floor 20, close to the front overlap area 22, so as to improve the load-bearing capacity of the cargo box flat floor 20 at the front overlap area 22. Further, the plurality of cross beams 41 further include a rear cross beam 43, the cargo box flat floor 20 further includes a rear overlap area 24 for overlapping with the rear frame 51, and the rear cross beam 43 is fixedly connected to the bottom of the cargo box flat floor 20, close to the rear overlap area 24, so as to improve the load-bearing capacity of the cargo box flat floor 20 at the rear overlap area 24.

[0052] In one embodiment, the cargo box floor assembly further includes a reinforcing beam assembly, and the cargo box flat floor 20 further includes a middle area 23, wherein the reinforcing beam assembly is fixedly connected to the cross beam 41 in the middle area 23. It is easy to understand that the middle area 23 of the cargo box flat floor 20 is generally installed with a rear axle assembly. Limited by the structure of the rear axle assembly, the spacing between adjacent cross beams 41 in the middle area 23 is generally large, and the middle area 23 of the cargo box flat floor 20 is generally also a key position for carrying goods. Therefore, in this embodiment, by adding a reinforcing beam assembly fixedly connected to the cross beam 41 in the middle area 23, the support stiffness of the cross beam 41 can be increased, so as to enhance the support strength of the cargo box flat floor 20 in the middle area 23, thereby preventing the left and right sides of the middle area 23 from being deformed too much and breaking.

[0053] In one embodiment, the reinforcement beam assembly includes a reinforcement longitudinal beam 62, and the reinforcement longitudinal beam 62 is fixedly connected to two adjacent cross beams 41 in the middle area 23. The reinforcement longitudinal beam 62 can form a more solid frame structure with the cross beams 41 by connecting the adjacent cross beams 41, thereby providing a better support effect for the cargo box flat floor 20, thereby improving the load-bearing capacity of the cargo box flat floor 20 in the middle area 23.

[0054] refer to Figure 8 , Fig. 9 Combined with Figure 5 In one embodiment, the reinforcing beam assembly further includes a reinforcing crossbeam 61, which is cross-arranged with the reinforcing longitudinal beam 62, and the reinforcing crossbeam 61 and the reinforcing longitudinal beam 62 are connected at the intersection. The cross-arrangement of the reinforcing crossbeam 61 and the reinforcing longitudinal beam 62 forms a more complex and sturdy frame structure. This structure can not only withstand the vertical load from above the floor, but also effectively resist the force from the side and oblique direction, thereby enhancing the overall structural stability of the cargo box floor assembly, and further preventing the middle area 23 from being deformed too much and breaking on both sides along the width direction (i.e., the left and right direction). In addition, the reinforcing crossbeam 61 and the reinforcing longitudinal beam 62 are connected at the intersection, which can promote the uniform distribution of stress at the intersection and avoid stress concentration.

[0055] In one embodiment, the reinforcing cross beam 61 and the reinforcing longitudinal beam 62 may be in a U-shaped beam structure, but are not limited thereto. For example, in some other embodiments, the structures of the reinforcing cross beam 61 and the reinforcing longitudinal beam 62 may be consistent with the structure of the above-mentioned cross beam 41 .

[0056] In one embodiment, the cargo box floor assembly further includes side frames 52 connected to both sides of the cargo box flat floor 20, and the aforementioned reinforcing beam 61 may be fixedly connected between the two side frames 52, but is not limited thereto.

[0057] Please refer to Fig.10 Combined with Figure 4and Figure 5 The embodiment of the present application also provides a cargo box assembly, including a cargo box front panel 10, a cargo box side panel 72, a cargo box tail panel 71 and the cargo box bottom panel assembly described in any of the above embodiments; wherein the cargo box front panel 10 is connected to the front end of the cargo box flat bottom panel 20, the cargo box side panel 72 is connected to the side end of the cargo box flat bottom panel 20, and the cargo box tail panel 71 is connected to the rear end of the cargo box flat bottom panel 20, and the cargo box front panel 10, the cargo box side panel 72, the cargo box tail panel 71 and the cargo box flat bottom panel 20 together form a cargo box body.

[0058] In one embodiment, the cargo box tail plate 71 can be hinged to the cargo box flat bottom plate 20, so that the cargo box tail plate 71 can rotate relative to the cargo box flat bottom plate 20, thereby opening the rear of the cargo box body. Similarly, each cargo box side panel 72 can also be hinged to the cargo box flat bottom plate 20, so that the cargo box side panel 72 can rotate relative to the cargo box flat bottom plate 20, thereby opening both sides of the cargo box body.

[0059] An embodiment of the present application also provides a vehicle, including a cargo box floor assembly or a cargo box assembly as described in any of the above embodiments. The vehicle may be an internal combustion engine vehicle, or a truck, van, sport utility vehicle, or any other type of vehicle with a battery. In one embodiment, the vehicle is a high-voltage traction battery-powered electric vehicle (e.g., a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), etc.). In another embodiment, the vehicle is an autonomous vehicle that controls the maneuvering functions of the vehicle without direct input from a human driver.
