TECHNICAL FIELD
[0001] The utility model belongs to the technical field of packing box, specifically relates to a packing box for loading display panel. BACKGROUND
[0002] In the process of carrying display panel, in order to avoid liquid crystal display panel from being damaged due to collision during carrying, packing box is usually used to load it. At present, the commonly used mode is to stack multiple display panels in a packing box, and the adjacent two display panels are separated by buffer material, and then the packing box is nested in an upper and lower mode to realize packing and delivery.
[0003] The existing packing box is designed with the PCB (Printed Circuit Board) avoidance area and the liquid crystal panel avoidance area of the same height at the bottom of the box body. However, in the display panel, most of the components on the PCB end are higher than the glass thickness on the liquid crystal panel end, so the stacking height on the PCB end will exceed the stacking height on the liquid crystal panel end. This leads to a small gap in the avoidance area of the PCB, which easily causes the upper box to press the PCB in the lower box, thereby causing product damage. In addition, the small gap in the PCB avoidance area also limits the high component distribution design on the PCB end, increasing the design cost. SUMMARY

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0034] Please see Figures 1-4 , Figure 1 A structural schematic view of the packaging box for loading display panels is provided by the embodiment of the utility model. Figure 2 A bottom schematic view of the packaging box for loading display panels is provided by the embodiment of the utility model.

Figure 4 A schematic view of loading display panels by using the packaging box is provided by the embodiment of the utility model.
[0035] The utility model provides a kind of packaging box for loading display panels, wherein, display panel includes liquid crystal panel 100 and the PCB 200 flexibly connected with liquid crystal panel 100. Packaging box includes box 1, box 1 has bottom plate 2;
[0036] The inner surface of bottom plate 2 is provided with first area 21 for placing liquid crystal panel and second area 22 for placing PCB, and second area 22 is sunk a certain height D along the direction of vertical outward relative to first area 21;
[0037] The outer surface of bottom plate 2 is provided with third area 23, fourth area 24 and fifth area 25;Third area 23 is arranged relative to first area 21 to realize the avoidance of liquid crystal panel;Fourth area 24 is arranged relative to second area 22 to realize the avoidance of PCB;Fifth area 25 is located at the edge of the outer surface of bottom plate 2 to realize the avoidance of packaging box clamping surface area;
[0038] The fourth area 24 is provided with a sunken part 3; the sunken part 3 is sunken in a vertical direction inward by a height H relative to the third area 23.
[0039] In the embodiment, the first area 21 can also be referred to as a liquid crystal panel placement area, the second area 22 can also be referred to as a PCB placement area, the third area 23 can also be referred to as a liquid crystal panel avoiding area, the fourth area 24 can also be referred to as a PCB avoiding area, and the fifth area 25 can also be referred to as a packaging box clamping surface avoiding area.
[0040] It can be understood that the sunken height of the sunken part 3 needs to be less than the thickness of the bottom plate 2, so as to ensure that the sunken part 3 does not penetrate the bottom plate 2.
[0041] Similarly, the length and width of the sunken part 3 should be less than the length and width of the fourth area 24, i.e., the PCB avoiding area, so as to ensure that the sunken part 3 does not penetrate the side wall of the box body 1.
[0042] Optionally, as an implementation manner, the height of the sunken part 3 is not more than the height of the fifth area 25, i.e., the packaging box clamping surface avoiding area. In this way, the packaging box clamping surface avoiding design can be met, and the PCB below can also be well protected.
[0043] Further, please continue to refer to Figure 4 Since the gap value on one side of the liquid crystal panel = the gap value on one side of the PCB, i.e.,

[0048] For example, in the packaging box shown in Figure 2 , a rectangular sunken part 3 is designed at the middle position of the PCB avoiding area on the outer surface of the bottom plate 2. For another example, in the packaging box shown in Figure 5The middle position of the PCB avoiding area on the outer surface of the bottom plate 2 of the packaging box is designed with a trapezoidal sunken part 3.
[0049] Optionally, as an implementation form, when the fourth area 24 is provided with a plurality of sunken parts 3, the plurality of sunken parts 3 can be uniformly arranged in the fourth area 24.
[0050] For example, in Figure 6 The middle position of the PCB avoiding area on the outer surface of the bottom plate 2 of the packaging box is designed with a trapezoidal sunken part 3 and a square sunken part 3, and the two sunken parts are uniformly distributed on both sides of the PCB avoiding area.
[0051] In another embodiment of the utility model, the sunken part 3 can further include a plurality of sunken transition zones 31, the plurality of sunken transition zones 31 have different heights and are distributed in a stepped manner, wherein the height of the sunken transition zone 31 adjacent to the third area 23 is higher than the height of the sunken transition zone 31 away from the third area 23.
[0052] Optionally, in the embodiment, the plurality of sunken transition zones 31 can have one or a plurality of combinations of a square shape, a trapezoidal shape and a semicircular shape.
[0053] For example, in Figure 7 The middle position of the PCB avoiding area on the outer surface of the bottom plate 2 of the packaging box is designed with a trapezoidal sunken part 3 and a square sunken part 3, and the two sunken parts are uniformly distributed on both sides of the PCB avoiding area.
[0054] In conclusion, it can be seen that, in the design for avoiding PCB, the shape, number, position and form of the sunken part 3 can have a plurality of implementation forms, and in the specific application, the relevant personnel can select at will according to the actual situation.
