[0021] like Figures 1-4 As shown, this utility model provides a cargo box floor plate 3 assembly, a cargo box, and a vehicle.

[0022] In an exemplary embodiment, the cargo box floor 3 assembly includes a floor 3 component, which includes a frame and a floor 3. The floor 3 is mounted on the frame, which includes crossbeams 2 and longitudinal beams 1. The crossbeams 2 are mounted on the longitudinal beams 1. Specifically, multiple longitudinal beams 1 are spaced apart, and multiple crossbeams 2 are spaced apart along the length of the longitudinal beams 1. The crossbeams 2 are spaced apart and perpendicular to the longitudinal beams 1. Openings are provided on the longitudinal beams 1, and the crossbeams 2 can be inserted into the openings for fixation. After the crossbeams 2 are inserted into the longitudinal beams 1, their upper surfaces are flush and in contact with the lower surface of the floor 3 to form a stable supporting force on the floor 3. First side beam components are provided at the front and rear ends of the longitudinal beams 1, and the first side beam components form a first step. At the same time, second side beam components are provided at the left and right ends of the crossbeams 2, and the second side beam components form a second step.

[0023] In this embodiment, by setting a first step and a second step at both ends of the crossbeam 2 and the longitudinal beam 1 respectively, the first side beam assembly and the second side beam assembly can form an effective waterproof structure after the cargo box is assembled. Compared with the prior art, this utility model does not require the use of sealant and can achieve effective waterproofing through the stepped structure, which simplifies the processing technology of the cargo box and improves the waterproof performance of the cargo box.

[0024] In an exemplary embodiment, the first side beam assembly includes a pair of support beams 4, which are respectively disposed at the front and rear ends of the longitudinal beam 1, and the support beams 4 are bent to form a first step.

[0025] In this embodiment, the two support beams 4 in the first side beam assembly are respectively disposed at the front end and rear end of the longitudinal beam 1, as shown in the figure. Figure 4 As shown, after multiple bends, the first step is formed at the front and rear of the cargo box. The first step at the front is used to abut against the front panel 11 of the cargo box. The cargo box door panels installed at the rear do not need to abut against each other. The structure of the step can also achieve waterproof function.

[0026] For example, the first side beam assembly further includes a first connector 5, which is disposed on the support beam 4. The first step has a first positioning surface 401 and a second positioning surface 402. The first connector 5 has a first mating surface 501 and a second mating surface 502. The first mating surface 501 is detachably connected to the first positioning surface 401, and the second mating surface 502 is detachably connected to the second positioning surface 402. In this embodiment, the first connector 5 is mainly used to contact the front enclosure 11 to prevent the front enclosure 11 of the cargo box from directly contacting the support beam 4 and causing deformation or damage to the support beam 4.

[0027] For example, in this embodiment, the detachable connection between the first positioning surface 401 and the first mating surface 501 is achieved by riveting. During installation, the first rivet 6 can be used to fix the first connecting piece 5 and the support beam 4 vertically from top to bottom, simplifying the installation structure. The second mating surface 502 and the second positioning surface 402 are fixed by bolts 7, and the connection between the first positioning surface 401 and the first mating surface 501 on the front crossbeam 2 can also be omitted during installation.

[0028] For example, in this embodiment, the support beam 4 is also provided with a first overlapping surface 403, and the edge of the base plate 3 overlaps on the first overlapping surface 403, thereby providing stable support for the edge of the base plate 3 and improving the strength of the base plate 3.

[0029] It is worth noting that in this embodiment, the longitudinal beam 1 has a first support portion at both ends, and the support beam 4 has a first placement surface. The first placement surface overlaps with the first support portion. Specifically, the first support portion consists of a first clearance groove 101 opened at both ends of the longitudinal beam 1 and a mounting plate 102 installed on the first clearance groove 101. Therefore, the first support portion enables the placement surface of the support beam 4 to be fixed in the L-shaped first clearance groove 101 and to be in firm contact with the mounting plate 102. The first support portions of the two longitudinal beams 1 can provide good support performance for the support beam 4.

[0030] It should also be noted that in this embodiment, one or more welding plates 103 are provided on the longitudinal beam 1. The welding plates 103 can be welded to the support beam 4 to fix the support beam 4.

[0031] In one exemplary embodiment, the second side beam assembly includes a side beam 8 disposed at both ends of the crossbeam 2, and the side beam 8 is bent to form a second step.

[0032] In this embodiment, the two side beams 8 in the second side beam assembly are respectively disposed at the left and right ends of the crossbeam 2, as shown in the figure. Figure 4 As shown, after multiple bends, a second step is formed at the left and right ends of the cargo box. The side panels 12 on the left and right sides of the cargo box abut against the second step, thereby achieving an effective waterproof structure without the need for sealing with sealant.

[0033] For example, the second side beam assembly also includes a second connector 9, which is disposed on the side beam 8. The second step has a third positioning surface 801 and a fourth positioning surface 802. The second connector 9 has a third mating surface 901 and a fourth mating surface 902. The third mating surface 901 is detachably connected to the third positioning surface 801, and the fourth mating surface 902 is detachably connected to the fourth positioning surface 802. In this embodiment, the second connector 9 is mainly used to contact the side wall 12 to prevent the side wall 12 of the cargo box from directly contacting the side beam 8, which could cause deformation or damage to the side beam 8. Specifically, in this embodiment, the detachable connection between the third positioning surface 801 and the third mating surface 901 is achieved by riveting. During installation, the second rivet 10 can be used to fix the second connector 9 to the side beam 8 vertically from top to bottom, simplifying the installation structure. The fourth mating surface 902 and the fourth positioning surface 802 are fixed by bolts 7. Alternatively, the connecting parts between the fourth mating surface 902 and the fourth positioning surface 802 can be omitted to simplify the installation process.

[0034] For example, in this embodiment, the side beam 8 is also provided with a second overlapping surface, and the left and right edges of the base plate 3 overlap the second overlapping surface, so as to provide stable support for the edges of the base plate 3 and improve the strength of the base plate 3.

[0035] It is worth noting that in this embodiment, the left and right ends of the crossbeam 2 are provided with second support parts, and the side beam 8 is provided with a second placement surface. The second placement surface overlaps with the second support parts. Specifically, the second support parts are L-shaped second clearance grooves 201 opened at both ends of the crossbeam 2. Therefore, the second support parts enable the placement surface of the support beam 4 to be fixed in the L-shaped second clearance groove 201. The multiple second support parts formed by multiple crossbeams 2 can provide good support performance for the side beam 8.

[0036] This utility model also provides a cargo box, which includes the above-mentioned cargo box bottom plate 3 assembly.

[0037] This utility model also provides a vehicle that includes the above-mentioned cargo box floor 3 assembly.

[0038] In summary, by setting a first step and a second step at both ends of the crossbeam 2 and the longitudinal beam 1 respectively, this utility model enables the first side beam assembly and the second side beam assembly to form an effective waterproof structure after the cargo box is assembled. Compared with the prior art, this utility model does not require the use of sealant and can achieve effective waterproofing through the stepped structure, simplifying the cargo box processing technology and improving the waterproof performance of the cargo box.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
