[0040] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] Reference below Figures 1-11 The cargo box floor assembly 100 according to the first embodiment of the present invention is described.

[0042] like Figures 1-8 As shown, according to the cargo box floor assembly 100 of the embodiment of the first aspect of the present invention, the cargo box floor assembly 100 includes: a frame, a plurality of cross beams 20, a first locking structure 30, a longitudinal beam 40 and a second locking structure 50.

[0043] The frame has two first frame beams 10 extending front to back and spaced apart from each other left to right; a plurality of cross beams 20 extending left to right and spaced apart in the front to back direction, and both ends of each cross beam 20 are slidably connected to the first frame beam 10 along the front to back direction; a first locking structure 30 is connected between the cross beam 20 and the first frame beam 10 for locking the cross beam 20 on the first frame beam 10; a longitudinal beam 40 is provided on the lower side of the plurality of cross beams 20, and each cross beam 20 is slidably connected to the longitudinal beam 40 along the front to back direction; a second locking structure 50 is connected between the longitudinal beam 40 and the cross beam 20 for locking the cross beam 20 on the longitudinal beam 40.

[0044] For example Figure 1As shown, there are two first frame beams 10, arranged in the front-to-back direction and spaced apart from each other. Furthermore, the two first frame beams 10 are parallel to each other. For example, the number of crossbeams 20 can be six, seven, eight, nine, ten, or more, with multiple crossbeams 20 arranged in the left-to-right direction and spaced apart from each other. Furthermore, the multiple crossbeams 20 are parallel to each other, and the spacing between the crossbeams 20 can be flexibly adjusted according to actual needs. For example, the number of longitudinal beams 40 can be two, arranged in the front-to-back direction and spaced apart from each other from each other. Furthermore, the two longitudinal beams 40 are parallel to each other.

[0045] For example Figure 1-Figure 5 As shown, a first locking structure 30 is connected between the left end of the crossbeam 20 and the left first frame beam 10, and a first locking structure 30 is connected between the right end of the crossbeam 20 and the right first frame beam 10. The first locking structures 30 at both ends of the crossbeam 20 can effectively fix multiple crossbeams 20 on the first frame beam 10. For example Figure 1 、 Figure 6 and Figure 7 As shown, the longitudinal beams 40 are provided on the lower side of the plurality of cross beams 20 , and the connection between the cross beams 20 and the longitudinal beams 40 is provided with a second locking structure 50 , which can effectively fix the plurality of cross beams 20 on the longitudinal beams 40 .

[0046] In this embodiment, when the distance between the multiple cross beams 20 needs to be adjusted, the constraint between the cross beam 20 and the first frame beam 10 can be effectively released by adjusting the first locking structure 30 between the cross beam 20 and the first frame beam 10, and the constraint between the cross beam 20 and the longitudinal beam 40 can be effectively released by adjusting the second locking structure 50 between the cross beam 20 and the longitudinal beam 40. Thus, by simultaneously releasing the constraints between the cross beam 20 and the first frame beam 10 and the longitudinal beam 40, the cross beam 20 can be allowed to slide in the front-to-back direction, thereby effectively adjusting the distance between the multiple cross beams 20.

[0047] When multiple crossbeams 20 need to be secured, the crossbeams 20 can be effectively secured to the first frame beam 10 by adjusting the first locking structure 30 between the crossbeam 20 and the first frame beam 10. The crossbeams 20 can be effectively secured to the longitudinal beam 40 by adjusting the second locking structure 50 between the crossbeam 20 and the longitudinal beam 40. By securing the crossbeam 20 to both the first frame beam 10 and the longitudinal beam 40, the crossbeam 20 can be effectively secured to the cargo box floor assembly 100. This allows for adjustable distances between multiple crossbeams 20, effectively meeting actual needs, facilitating resource management for cargo boxes of the same size, and reducing production and manufacturing costs.

[0048] According to the cargo box floor assembly 100 of the embodiment of the present invention, by setting a frame, multiple cross beams 20, a first locking structure 30, a longitudinal beam 40 and a second locking structure 50, the frame has two first frame beams 10 extending front and back and arranged at intervals left and right, multiple cross beams 20 extending left and right and arranged at intervals in the front and back directions, both ends of each cross beam 20 are slidably connected to the first frame beam 10 along the front and back, and the first locking structure 30 is connected between the cross beam 20 and the first frame beam 10 for locking the cross beam 20 On the first frame beam 10, the longitudinal beam 40 is arranged on the lower side of multiple cross beams 20, and each cross beam 20 is slidably connected to the longitudinal beam 40 in the front-to-rear direction. The second locking structure 50 is connected between the longitudinal beam 40 and the cross beam 20 to lock the cross beam 20 on the longitudinal beam 40, enabling multiple cross beams 20 to slide in the front-to-rear direction and be fixed on the cargo box floor assembly 100, thereby effectively adjusting the spacing between the multiple cross beams 20, thereby effectively improving applicability and reducing costs, and facilitating the management of cargo box resources of the same size.

[0049] In one embodiment of the present invention, Figure 4 and Figure 7 As shown, the cargo box floor assembly 100 further includes: a first connecting plate 61 and a second connecting plate 62 .

[0050] One end of the first connecting plate 61 is slidably connected to the first frame beam 10, and the other end is fixed to the cross beam 20. The first locking structure 30 is connected between the first connecting plate 61 and the first frame beam 10. One end of the second connecting plate 62 is slidably connected to the longitudinal beam 40, and the other end is fixed to the cross beam 20. The second locking structure 50 is connected between the second connecting plate 62 and the longitudinal beam 40.

[0051] When the distance between multiple crossbeams 20 needs to be adjusted, the first locking structure 30 between the first connecting plate 61 and the first frame beam 10 and the second locking structure 50 between the second connecting plate 62 and the longitudinal beam 40 can be adjusted to release the constraints between the first connecting plate 61 and the first frame beam 10 and the constraints between the second connecting plate 62 and the longitudinal beam 40. As a result, the crossbeams 20 can be effectively moved, thereby achieving adjustable spacing between the crossbeams 20.

[0052] In this embodiment, a first connecting plate 61 and a second connecting plate 62 are provided in the cargo box floor assembly 100. One end of the first connecting plate 61 is slidably connected to the first frame beam 10, and the other end is fixed to the cross beam 20. The first locking structure 30 is connected between the first connecting plate 61 and the first frame beam 10. One end of the second connecting plate 62 is slidably connected to the longitudinal beam 40, and the other end is fixed to the cross beam 20. The second locking structure 50 is connected between the second connecting plate 62 and the longitudinal beam 40, which can effectively ensure the reliability and stability of the connection between the cross beam 20 and the first frame beam 10 and the longitudinal beam 40.

[0053] In one embodiment of the present invention, Figure 4 、 Figure 5 and Figure 7 As shown, the first frame beam 10 and the longitudinal beam 40 are both formed with a first locking groove 401 extending forward and backward, and the first retaining ribs 4011 extending toward each other are formed on the opposite side walls of the first locking groove 401. The two first retaining ribs 4011 cooperate to define the opening of the first locking groove 401. The first connecting plate 61 and the second connecting plate 62 are formed with a first locking hole. Either of the first locking structure 30 and the second locking structure 50 includes: a first fastener 31 and a first locking nut 32. The first fastener 31 includes The first screw head 311 and the first screw rod 312, the first screw head 311 is fitted in the first locking groove 401 and is located on the side of the bottom wall of the first retaining rib 401 facing the first locking groove 401, in the width direction of the first locking groove 401, the size of the first screw head 311 is larger than the size of the opening of the first locking groove 401, one end of the first screw rod 312 extends into the first locking groove 401 and is connected to the first screw head 311, and the other end of the first screw rod 312 passes through the first locking hole and is threadedly connected to the first locking nut 32.

[0054] For example Figure 4 、 Figure 5 and Figure 7 As shown, the first retaining rib 4011 on the upper side of the first locking groove 401 extends downward, and the first retaining rib 4011 on the lower side of the first locking groove 401 extends upward. An opening of the first locking groove 401 is formed between the two first retaining ribs 4011 on the upper and lower sides of the first locking groove 401. The opening width of the first locking groove 401 in the vertical direction is smaller than the size of the first screw head 311. Furthermore, the first fastener 31 can slide in the front-to-back direction. For example Figure 4 and Figure 5 As shown, a thread is provided on the outer peripheral surface of the first screw 312, the left end of the first screw 312 extends into the first locking groove 401 and is fixedly connected to the first screw head 311, the first connecting plate 61 is arranged between the first locking nut 32 and the first frame beam 10, and the right end of the first screw 312 passes through the first locking hole on the first connecting plate 61 and is threadedly connected to the first locking nut 32.

[0055] When the distance between the multiple crossbeams 20 needs to be adjusted, the first locking nut 32 between the crossbeam 20 and the first frame beam 10 and the first locking nut 32 between the crossbeam 20 and the longitudinal beam 40 are first loosened. Then, the crossbeam 20 is moved as needed. That is, when the crossbeam 20 moves in the front-to-back direction, the first fastener 31 and the first locking nut 32 move along with the crossbeam 20, wherein the first fastener 31 can slide in the front-to-back direction within the first locking groove 401. When the crossbeam 20 needs to be fixed, the first locking nut 32 between the crossbeam 20 and the first frame beam 10 and the first locking nut 32 between the crossbeam 20 and the longitudinal beam 40 are tightened to fix the crossbeam 20 to the first frame beam 10 and the longitudinal beam 40.

[0056] In this embodiment, a first locking groove 401 extending forward and backward is provided on both the first frame beam 10 and the longitudinal beam 40, and first retaining ribs 4011 extending toward each other are formed on the opposite side walls of the first locking groove 401. The two first retaining ribs 4011 cooperate to define the opening of the first locking groove 401, and a first locking hole is formed on the first connecting plate 61 and the second connecting plate 62. Any one of the first locking structure 30 and the second locking structure 50 includes: a first fastener 31 and a first locking nut 32, the first fastener 31 includes a first screw head 311 and a first screw rod 312, the first screw head 311 is fitted in the first locking groove 401 and is located at the first retaining rib 401 1, on the side of the bottom wall facing the first locking groove 401, the size of the first screw head 311 is larger than the size of the opening of the first locking groove 401 in the width direction of the first locking groove 401. One end of the first screw rod 312 extends into the first locking groove 401 and is connected to the first screw head 311. The other end of the first screw rod 312 passes through the first locking hole and is threadedly connected to the first locking nut 32. This can limit the movement of the first fastener 31 in the width direction of the first locking groove 401 and enable the first fastener 31 to slide in the first locking groove 401 in the front-to-back direction without disengaging, thereby effectively improving the reliability of the sliding of the crossbeam 20 and the stability of the fixation of the crossbeam 20. In addition, the first fastener 31 and the first locking nut 32 have a simple structure and are easy to operate when moving the crossbeam 20, thereby effectively improving the efficiency of the movement of the crossbeam 20.

[0057] In one embodiment of the present invention, Figure 2-Figure 6 As shown, a plurality of first locking grooves 401 are formed on either the first frame beam 10 or the longitudinal beam 40, and the plurality of first locking grooves 401 are arranged in an interval up and down. For example, the first frame beam 10 may have a plurality of first locking grooves 401, and the number of first locking grooves 401 may be two, three, four, five, or six or more.

[0058] For example, a plurality of first locking grooves 401 are formed on the longitudinal beam 40, and the number of the first locking grooves 401 can be two, three, four, five or more than six.

[0070] In one embodiment of the present invention, Figures 9-11 As shown, a connecting groove 801 opening downward is formed on the reinforcing beam 80, and the cargo box floor assembly 100 also includes: a connecting member 90, one end of the connecting member 90 is slidably engaged in the connecting groove 801 along the front-to-back direction, and the other end of the connecting member 90 is connected to the cross beam 20.

[0071] When it is necessary to adjust the distance between multiple cross beams 20, after adjusting the first locking structure 30 between the first connecting plate 61 and the first frame beam 10 and the second locking structure 50 between the second connecting plate 62 and the longitudinal beam 40, adjust the connecting piece 90 between the reinforcing beam 80 and the cross beam 20, thereby releasing the constraints between the cross beam 20 and the first frame beam 10, the longitudinal beam 40 and the reinforcing beam 80, so that the cross beam 20 can slide in the front and rear directions.

[0072] In this embodiment, a downward-opening connecting groove 801 is provided on the reinforcing beam 80, and the cargo box floor assembly 100 also includes a connecting member 90. One end of the connecting member 90 is slidably engaged in the connecting groove 801 along the front-to-back direction, and the other end of the connecting member 90 is connected to the cross beam 20, which can effectively limit the sliding direction of the cross beam 20, thereby further ensuring the sliding reliability of the cross beam 20 and the stability of the fixation of the cross beam 20.

[0073] In one embodiment of the present invention, Figures 9-11 As shown, second retaining ribs 8011 extending toward each other are formed on the opposite side walls of the connecting groove 801, and the two second retaining ribs 8011 cooperate to define the opening of the connecting groove 81. A through hole is formed on the crossbeam 20, and the connecting member 90 includes a second fastener 91 and a second locking nut 92. The second fastener 91 includes a second screw head 911 and a second screw rod 912. The second screw head 911 is fitted into the connecting groove 801 and is located on the side of the second retaining rib 8011 facing the bottom wall of the connecting groove 801. In the width direction of the connecting groove 801, the size of the second screw head 911 is larger than the size of the opening of the connecting groove 801. One end of the second screw rod 912 extends into the connecting groove 801 and is connected to the second screw head 911. The other end of the second screw rod 912 passes through the through hole and is threadedly connected to the second locking nut 92.

[0074] For example Figure 11 As shown, the second retaining rib 8011 on the left side of the connecting groove 801 extends rightward, and the second retaining rib 8011 on the right side of the connecting groove 801 extends leftward. An opening of the connecting groove 801 is formed between the two second retaining ribs 8011 on the left and right sides of the connecting groove 801. When it is necessary to adjust the distance between multiple crossbeams 20, first loosen the first locking nut 32 between the crossbeam 20 and the first frame beam 10 and the first locking nut 32 between the crossbeam 20 and the longitudinal beam 40, and then loosen the second locking nut 92 between the crossbeam 20 and the reinforcing beam 80. Thereafter, the crossbeam 20 is moved as needed. That is, when the crossbeam 20 moves in the front-to-back direction, the second fastener 91 and the second locking nut 92 move with the crossbeam 20, wherein the second fastener 91 can slide in the front-to-back direction within the connecting groove 801. When it is necessary to fix the crossbeam 20, tighten the first locking nut 32 between the crossbeam 20 and the first frame beam 10 and the first locking nut 32 between the crossbeam 20 and the longitudinal beam 40, and then tighten the second locking nut 92 between the crossbeam 20 and the reinforcing beam 80, thereby effectively fixing the crossbeam 20 on the base plate 70.

[0075] In this embodiment, second retaining ribs 8011 extending toward each other are formed on the opposite side walls of the connecting groove 801. The two second retaining ribs 8011 cooperate to define the opening of the connecting groove 81. A through hole is formed on the crossbeam 20. The connecting member 90 includes a second fastener 91 and a second locking nut 92. The second fastener 91 includes a second screw head 911 and a second screw rod 912. The second screw head 911 is fitted into the connecting groove 801 and is located on the side of the second retaining rib 8011 facing the bottom wall of the connecting groove 801. Upward, the size of the second screw head 911 is larger than the size of the opening of the connecting groove 801. One end of the second screw rod 912 extends into the connecting groove 801 and connects to the second screw head 911. The other end of the second screw rod 912 passes through the through hole and is threadedly connected to the second locking nut 92. This can limit the movement of the second fastener 91 in the width direction of the connecting groove 801 and enable the second fastener 91 to slide in the connecting groove 801 in the front-to-back direction without disengaging, thereby effectively improving the reliability of the sliding of the crossbeam 20 and the stability of the fixation of the crossbeam 20. In addition, the second fastener 91 and the second locking nut 92 have a simple structure and are easy to operate when moving the crossbeam 20, thereby effectively improving the efficiency of the movement of the crossbeam 20.
