[0040] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0041] During the production and sales process, display screens need to be packed in boxes for transportation. This involves the operator placing the display screen into the box for packing before transportation, and then unpacking it when it arrives at the consumer or the next processing step. The consumer or operator needs to take the display screen out of the box.

[0042] Existing packaging boxes are usually made of corrugated cardboard, and tape is usually used to seal them when fixing them. However, the tape may be inconvenient when opening the box. After receiving the product, consumers or operators need to patiently peel off the tape or use tools to cut the tape to open the box, which may increase the time to open the box.

[0043] Moreover, some display screens are large in size, and it may be difficult and inconvenient to remove them from the top of the box, especially when there is not enough space or appropriate tools and the box is not damaged as much as possible. This undoubtedly causes a lot of inconvenience in taking and placing the display screen.

[0044] Furthermore, existing corrugated cardboard packaging boxes are mostly made of single-layer corrugated cardboard on all four sides, relying solely on the corrugated cardboard for longitudinal support. During transportation, multiple boxes carrying display screens are often stacked for ease of transport, relying solely on the corrugated cardboard for support. This can easily cause the bottom of the box to deform due to the heavy weight of the display screen, potentially damaging the display and causing significant problems in actual use.

[0045] This application embodiment provides a packaging box. Please refer to Figures 1-4 , Figure 1This is a schematic diagram of the structure of the packaging box provided in an embodiment of the present application; Figure 2 Schematic diagram of the structure of the bottom plate of the packaging box provided in an embodiment of the present application; Figure 3 This is a schematic structural diagram of a packaging box in a closed state provided by an embodiment of the present application; Figure 4 FIG1 is a schematic diagram of the structure of the packaging box provided by the embodiment of the present application in the open state. The packaging box 000 may include: a bottom plate 100, a back plate 200, a packaging cover plate 300 and two folding plates 400.

[0046] The bottom plate 100 may have a first side 110 and a second side 120 disposed opposite to each other in a first direction Y, and two third sides 130 disposed opposite to each other in a second direction X. One side of the back plate 200 is connected to the first side 110 of the bottom plate 100. For example, the back plate 200 may be fixedly connected to the bottom plate 100 by adhesive.

[0047] One side of the two folding plates 400 is respectively connected to the two sides of the back plate 200 that are opposite to each other in the second direction X, and is respectively slidably connected to the bottom plate 100 at positions close to the two third side edges 130 of the bottom plate 100; the folding plates 400 are configured to expand or fold and shrink in the first direction Y, so that the side of the folding plate 400 facing away from the back plate 200 can be stretched and retracted in the first direction Y.

[0048] One side of the packaging cover plate 300 is rotatably connected to the side of the back plate 200 facing away from the base plate 100, and the other side is detachably connected to the second side 120 of the base plate 100; wherein, after the packaging cover plate 300 is connected to the second side 120 of the base plate 100, a portion of the packaging cover plate 300 is located on the side of the two folding plates 400 facing away from the base plate 100, and the other portion is located on the side of the two folding plates 400 facing away from the back plate 200.

[0049] Please refer to Figure 3 and Figure 4 The folding plate 400 can be expanded or folded in the first direction Y, thereby partially opening or closing the side of the packaging box 000. When the packaging box 000 needs to be opened, the connection between the packaging cover plate 300 and the bottom plate 100 is released, and the packaging cover plate 300 is rotated and flipped open relative to the back plate 200. At this time, the top and front areas of the packaging box 000 are opened, and the folding plates 400 on both sides can be folded and contracted in the first direction Y, and the areas on both sides of the packaging box 000 can also be opened. In this way, the operator can easily remove the display screen from the packaging box 000.

[0050] like Figure 3As shown, when a display screen is to be placed within packaging box 000, the packaging cover 300 is snapped together and connected to the bottom plate 100 to seal the packaging box 000. In this case, the folding plate 400 has greater longitudinal strength than the single-layer corrugated cardboard of existing corrugated cardboard packaging boxes, achieving better compressive resistance. When multiple packaging boxes 000 are stacked, the gravity generated by the stacking of multiple packaging boxes carrying display screens can be avoided, thereby preventing deformation and damage to the packaging boxes 000, which in turn affects the protective performance of the packaging boxes 000.

[0051] The specific implementation of each plate body of the packaging box 000 and the connection relationship between the plates are described in detail below.

[0052] Please refer to Figure 5 , Figure 5 The figure is a schematic diagram of the structure of the folding plate of the packaging box provided in an embodiment of the present application. In this embodiment of the present application, the folding plate 400 includes a folding plate body 410 and a connecting post 420. One side of the folding plate body 410 is connected to the back panel 200, and the other side is connected to the connecting post 420. The connecting post 420 is slidably connected to the bottom panel 100 at a position near the third side 130 of the bottom panel 100.

[0053] By providing the connecting post 420, a sliding connection can be achieved between the connecting post 420 and the bottom plate 100, simplifying the implementation of the sliding connection between the folding plate 400 and the bottom plate 100. The operator or the consumer can operate the connecting post 420 to unfold or fold the folding plate body 410.

[0054] For example, the side of the folding plate body 410 near the back plate 200 can be snap-fitted or fixedly connected to the back plate 200, for example, by adhesive bonding. For another example, one of the back plate 200 and the side of the folding plate body 410 near the back plate 200 can be provided with a first connecting portion, such as a protrusion, and the other can be provided with a second connecting portion, such as a groove, that matches the first connecting portion. The folding plate 400 and the back plate 200 can be connected by snapping, and adhesive bonding can be further used to further reinforce the snapping.

[0055] Please refer to Figure 2 and Figure 5The base plate 100 may have a first guide structure 101 near the third side 130, and the end of the connecting post 420 facing the base plate 100 may have a second guide structure 421 slidably connected to the first guide structure 101. To ensure the reliability of the sliding connection between the folding plate 400 and the base plate 100, matching first guide structures 101 and second guide structures 421 may be provided on the base plate 100 and the connecting post 420 to guide the expansion and folding of the folding plate 400. The provision of the connecting post 420 provides a structural foundation for the second guide structure 421, eliminating the need for provision on the bottom of the folding plate body 410, thereby simplifying the design of the folding plate 400.

[0056] In some feasible embodiments, the first guide structure 101 may include a guide groove, the extension direction of which is parallel to the first direction Y; the second guide structure 421 may include a guide protrusion matching the guide groove; wherein, at least a portion of the guide protrusion is located in the guide groove and is slidably connected to the guide groove.

[0057] For example, Figure 2 and Figure 5 As shown, the guide protrusion can be a cylindrical protrusion with a "T"-shaped cross-section, and the guide groove corresponds to a groove with a "T"-shaped cross-section. At this time, the end of the T-shaped protrusion can be embedded in the guide groove. On the one hand, the guide groove can limit and guide the sliding direction of the connecting column 420. On the other hand, it can also prevent the guide protrusion from escaping from the guide groove, thereby ensuring the stability of the sliding connection between the folding plate 400 and the base plate 100.

[0058] Please refer to Figure 6 , Figure 6 It is a structural schematic diagram of the folding plate body of the folding plate provided in an embodiment of the present application; in the embodiment of the present application, the folding plate body 410 may include a plurality of first folding strips 411 and a plurality of second folding strips 412 alternately arranged in the second direction X, and the adjacent first folding strips 411 and the second folding strips 412 are rotatably connected; wherein, after the folding plate 400 is in the unfolded state, the angle α between the adjacent first folding strips 411 and the second folding strips 412 is less than or equal to 180°.

[0059] In some embodiments, both sides of the first folding strip 411 may be connected to one side of two adjacent second folding strips 412. In addition, both sides of the second folding strip 412 may be connected to one side of two adjacent first folding strips 411.

[0060] The folding plate body 410 is configured to expand or collapse by rotating the adjacent first and second folding strips 411, 412. When the connecting post 420 is driven, the first and second folding strips 411, 412 rotate, changing the angle α between them. When the angle α between the adjacent first and second folding strips 411, 412 is less than 180°, the folding plate body 410 forms a bent, force-bearing structure, with the first and second folding strips 411, 412 arranged in a “>” shape, and the three folding strips arranged in a “Z” shape. This provides greater strength and compressive resistance than single-layer corrugated cardboard.

[0061] In the embodiment of the present application, the first folding strip 411 and the second folding strip 412 can be folding strips of the same shape, arranged in different directions; the first folding strip 411 and the second folding strip 412 can also be folding strips of different shapes. The first folding strip 411 and the second folding strip 412 can be formed by splicing a single folding strip, or they can be formed by processing the same plate.

[0062] Please refer to Figure 5 and Figure 7 , Figure 7 The figure is a schematic diagram of the structure of the supporting auxiliary plate, packaging cover plate, and back plate of the packaging box provided in an embodiment of the present application. In this embodiment of the present application, the end of the connecting column 420 facing away from the base plate 100 may have a first limiting structure 422; the packaging cover plate 300 may have a second limiting structure 301 that matches the first limiting structure 422. When the folding plate body 410 is in the unfolded state and a portion of the packaging cover plate 300 is located on the side of the two folding plates 400 facing away from the base plate 100, the first limiting structure 422 connects to the second limiting structure 301.

[0063] When the packaging cover 300 is fastened onto the folding plate 400 and the connecting post 420 slides close to the second side 120 of the bottom plate 100, the first limiting structure 422 and the second limiting structure 301 can be mated and connected, thereby restricting the connecting post 420 from further movement in the first direction Y. When it is necessary to close the packaging box 000, the connecting post 420 is limited by the packaging cover 300, so that the folding plate 400 will not be further expanded or folded, and the side of the packaging box 000 can be sealed.

[0064] When it is necessary to open the packaging box 000, the connection between the packaging cover 300 and the bottom plate 100 is released, the packaging cover 300 is flipped open, the connection between the first limiting structure 422 and the second limiting structure 301 is released, and the connecting column 420 can move along the first direction Y, so that the folding plate body 410 can be folded and contracted, so that the side of the packaging box 000 can be opened.

[0065] In the embodiment of the present application, one of the first limiting structure 422 and the second limiting structure 301 may be a limiting protrusion; the other of the first limiting structure 422 and the second limiting structure 301 may be a limiting groove matching the limiting protrusion. Figure 5 and Figure 7 As shown, the first limiting structure 422 of the connecting pillar 420 may be a limiting groove, and the second limiting structure 301 of the package cover plate 300 may be a matching limiting protrusion.

[0066] Please refer to Figure 1 、 Figure 2 and Figure 7 The packaging box 000 may further include two auxiliary support panels 500. Both auxiliary support panels 500 are distributed between the two folding panels 400 in the second direction X, and the two auxiliary support panels 500 correspond one-to-one to the two folding panels 400. Each auxiliary support panel 500 is distributed close to the corresponding folding panel 400, and each auxiliary support panel 500 is detachably connected to the bottom panel 100. After the auxiliary support panels 500 are connected to the bottom panel 100, the side of the auxiliary support panels 500 facing away from the bottom panel 100 can be at the same height as the side of the folding panel 400 facing away from the bottom panel 100, and the auxiliary support panels 500 and the folding panel 400 can bear force together in the longitudinal direction.

[0067] like Figure 3 and Figure 4 As shown, after opening the flip packaging cover 300, the supporting auxiliary plate 500 is removed, and then the folding plate 400 is folded and shrunk. At this time, the side of the packaging box 000 can still be partially opened, and the side area will not be blocked due to the setting of the supporting auxiliary plate 500.

[0068] When the display needs to be boxed, the display is placed on the base plate 100, and the supporting auxiliary plate 500 is connected to the base plate 100. Then, the folding plate 400 is unfolded, the packaging cover plate 300 is fastened and connected to the base plate 100, and the boxing operation is completed.

[0069] By setting up a detachable support auxiliary plate 500, one side of the folding plate 400 can be supported, which is convenient for better protection of the packaging box 000 and improves the overall pressure resistance of the packaging box 000; the detachable support auxiliary plate 500 will not cause additional obstruction when the packaging box 000 is loading and unloading the display screen.

[0070] In some embodiments, such as Figure 1 、 Figure 2 and Figure 7As shown, the side of the auxiliary support plate 500 facing the base plate 100 may have an elastic clip 501, and the side of the base plate 100 facing the auxiliary support plate 500 may have a strip-shaped clipping groove 102 that cooperates with the elastic clip 501. After the auxiliary support plate 500 is connected to the base plate 100, at least a portion of the elastic clip 501 is located within the strip-shaped clipping groove 102; the extension direction of the strip-shaped clipping groove 102 is parallel to the first direction Y.

[0071] For example, the elastic clip 501 may be made of rubber material and is bonded to the bottom of the auxiliary support plate 500 . The elastic clip 501 is detachably connected to the strip-shaped slot 102 through elastic deformation.

[0072] Please refer to Figure 1 and Figure 7 The packaging cover plate 300 may include a top plate 310 and a front plate 320; one side of the top plate 310 is rotatably connected to the side of the back plate 200 facing away from the bottom plate 100, and the other side of the top plate 310 is rotatably connected to one side of the front plate 320; the side of the front plate 320 facing away from the top plate 310 is detachably connected to the bottom plate 100.

[0073] For example, a first latch 303 may be provided between the top plate 310 and the back plate 200 to achieve a rotational connection between the top plate 310 and the back plate 200 ; a second latch 302 may be provided between the top plate 310 and the front plate 320 to achieve a rotational connection between the top plate 310 and the front plate 320 .

[0074] By adopting the rotational connection between the top plate 310 and the front plate 320, the top plate 310 can be further rotated relative to the front plate 320, so that the upper and front areas of the packaging box 000 can be opened wider, making it easier to take and place the display screen.

[0075] In some embodiments, the front panel 320 has a first connection structure 322 on the side facing away from the top panel 310, and the second side 120 has a second connection structure 103 matching the first connection structure 322. The first connection structure 322 and the second connection structure 103 are detachably connected. The first connection structure 322 and the second connection structure 103 can be a threaded connection structure or a snap connection structure. Figure 2 and Figure 7 As shown, the first connection structure 322 may be a bolt, and the second connection structure 103 may be a matching threaded hole.

[0076] like Figure 2 and Figure 7As shown, a fixing seat 140 may be further provided at the bottom of the bottom plate 100, and the second connecting structure 103 may be disposed on the fixing seat 140; a connecting block 321 may be correspondingly provided on the side of the front plate 320 facing away from the top plate 310, and the first connecting structure 322 may be disposed on the connecting block 321. The connecting block 321 may be disposed at a position corresponding to the fixing seat 140.

[0077] In addition, if Figure 2 As shown, an anti-skid pad 150 can also be provided at the bottom of the fixing seat 140, which can prevent the packaging boxes 000 from slipping when the packaging boxes 000 are stacked, or prevent a single packaging box 000 from slipping during transportation, thereby improving stability during transportation.

[0078] It should be noted that the embodiments of the present application do not limit the materials of the base plate 100, the back plate 200, the packaging cover plate 300, the folding plate 400 and the supporting auxiliary plate 500. The above-mentioned plates can be formed by processing corrugated cardboard or calcium plastic cardboard, or can be plates of other available materials.

[0079] In summary, the packaging box provided by the embodiment of the present application is provided with two folding plates at positions close to the two third side edges of the bottom plate, and these two folding plates can serve as side plates, which can support the packaging cover plate after the packaging cover plate is connected to the bottom plate. When the packaging cover plate is disconnected from the bottom plate and the packaging cover plate is flipped open, the top and front areas of the packaging box are opened, and the folding plates on both sides can be folded and contracted toward the back plate, and part of the areas on both sides can also be opened, so that the operator can easily take out the display screen from the packaging box. Similarly, the operator can easily place the display screen into the packaging box, then unfold the folding plates on both sides, close the two side areas of the packaging box, and finally flip the packaging cover plate and connect it to the bottom plate, so that the top and front areas of the packaging box can be closed, thereby realizing convenient loading and unloading of the display screen.

[0080] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.

[0081] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
