Description

Technical Field

[0001] The present disclosure relates to the field of display technologies, and particularly to a packing box for a display panel. Background Art

[0002] With the continuous development of the display industry, flat-panel displays are increasingly unable to meet the needs of users.

[0003] Currently, curved-panel displays have emerged in the market. Curved-panel displays have advantages such as a wide viewing angle, a larger display area in a limited space, a rich and delicate feel, and an aesthetically pleasing arc-shaped appearance, and are increasingly favored by users. Utility Model Content

[0004] The purpose of some embodiments of the present disclosure is to provide a packing box for a display panel, which packs and transports the display panel in a curved-surface support manner, reduces the rebound stress of the display panel after display screen assembly, improves the problem of light leakage defects, and solves the light leakage problem.

[0005] Some embodiments of the present disclosure provide a packing box for a display panel, including a box body, a curved inner lining, and a box cover; the box body includes a bottom plate and a plurality of side plates, the plurality of side plates are arranged on one side of the first surface of the bottom plate and are connected to the first surface of the bottom plate, the plurality of side plates enclose a frame shape, and adjacent two side plates are connected, and the plurality of side plates and the bottom plate form a cavity; the curved inner lining is located in the cavity of the box body; the curved inner lining includes an opposite first surface and a second surface, the second surface of the curved inner lining is closer to the bottom plate relative to the first surface of the curved inner lining, the first surface of the curved inner lining is a curved surface protruding towards the second surface of the curved inner lining; the first surface of the curved inner lining is used to place the display panel; the box cover is located on the side of the plurality of side plates of the box body away from the bottom plate, and the box cover is adapted to the size of the box body.

[0006] The beneficial effects of some embodiments of the present disclosure are as follows: The first surface of the curved inner lining is set as a curved surface protruding towards the second surface of the curved inner lining. When the display panel is placed on the first surface of the curved inner lining, due to the weight of the display panel itself, the display panel will form a curved surface with the same curvature as the first surface of the curved inner lining and also protrude towards the second surface of the curved inner lining. In this way, the effect of placing the display panel in a curved shape is formed by relying on the self-weights of the curved inner lining and the display panel, realizing the curved surface support of the display panel. The display panels can be stacked and placed according to the set curvature and transported, ensuring that the display panel remains in a curved state from the production to the assembly of the display screen. This effectively reduces the rebound stress of the display panel after the display screen is assembled, significantly improves the problem of light leakage, and solves the light leakage problem. At the same time, the curved inner lining and the box body are designed separately, and only the curved inner linings with different curvatures are molded.

The lining limiting structure is disposed on the first surface of the bottom plate and is connected to the first surface of the bottom plate; a limiting groove corresponding to the lining limiting structure is further provided on the second surface of the curved lining, and the lining limiting structure is engaged with the limiting groove.

[0013] In some embodiments, a hand - holding groove is provided at the middle position of at least one side plate. In the direction perpendicular to the second surface of the curved lining, the hand - holding groove penetrates through the orthographic projection of the curved lining on this side plate; a lining hand - holding groove is provided at the position corresponding to the hand - holding groove on the second surface of the curved lining.

[0014] In some embodiments, the bottom plate further includes a second surface away from the plurality of side plates, and a box - body hand - holding groove is provided at the edge of the second surface of the bottom plate.

[0015] In some embodiments, a reinforcing rib structure is provided on the second surface of the bottom plate, and the reinforcing rib structure includes a plurality of hollow openings.

[0032] Next, the technical solutions in some embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0033] Unless the context requires otherwise, throughout the specification and claims, the term "comprising" is to be construed in an open, inclusive sense, i.e., "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples", "specific examples", or "some examples", etc. are intended to indicate that a specific feature, structure, material, or characteristic related to the embodiment or example is included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials, or characteristics described above may be included in any one or more embodiments or examples in any suitable manner.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0035] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connected" may be a fixed connection, a detachable connection, or an integral body; it may be directly connected or indirectly connected through an intermediate medium. The term "coupled" indicates, for example, that two or more components have direct physical contact or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content herein.

[0036] "At least one of A, B, and C" has the same meaning as "at least one of A, B, or C", and both include the following combinations of A, B, and C: only A, only B, only C, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B, and C.

[0037] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0038] As used herein, "about", "substantially", or "approximately" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0039] As used herein, "parallel", "perpendicular", and "equal" include the stated situations and situations similar to the stated situations, where the range of the similar situations is within an acceptable deviation range, and the acceptable deviation range is determined by a person of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, that the difference between the two equal values is less than or equal to 5% of either one of them.

[0040] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and the area of regions are enlarged for clarity. Accordingly, variations in the shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Thus, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but include shape deviations caused, for example, by manufacturing. For example, an etched region shown as rectangular will generally have curved features. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shape of the regions of the device and are not intended to limit the scope of the exemplary embodiments.

[0041] With the continuous development of curved screen displays, more and more problems have emerged. For example, when assembling a curved screen display, first, the display panel in the curved screen display needs to be bent. After the display panel reaches the set curvature, it is then assembled into a curved screen display. During the bending process of the display panel, reverse springback stress will be generated in the display panel, which will cause the assembled curved screen to be prone to light leakage, affecting the display effect of the curved screen display and reducing the quality of the curved screen display.

[0042] As Figure 1As shown, some embodiments of the present disclosure provide a packing box 100 for a display panel, including a box body 10, a curved inner lining 20, and a box cover 30; the box body 10 includes a bottom plate 12 and a plurality of side plates 11, the plurality of side plates 11 are arranged on one side of the first surface 121 of the bottom plate 12 and are connected to the first surface 121 of the bottom plate 12, the plurality of side plates 11 enclose a frame shape, and adjacent two side plates 11 are connected, the plurality of side plates 11 and the bottom plate 12 form a cavity A; the curved inner lining 20 is located in the cavity A of the box body 10. The curved inner lining 20 includes an opposite first surface 21 and a second surface 22, the second surface 22 of the curved inner lining 20 is closer to the bottom plate 12 relative to the first surface 21 of the curved inner lining 20, and the first surface 21 of the curved inner lining 20 is a curved surface protruding in the direction of the second surface 22 of the curved inner lining 20; the first surface 21 of the curved inner lining 20 is used to place the display panel; the box cover 30 is located on the side of the plurality of side plates 11 of the box body 10 away from the bottom plate 12, and the box cover 30 is dimensionally adapted to the box body 10.

[0043] Exemplarily, the display panel 1000 is used to display images; from the perspective of the light-emitting type of the display panel 1000, the display panel 1000 can be an active light-emitting display panel, such as an Organic Light-Emitting Diode (OLED) display panel, a Quantum Dot Light Emitting Diodes (QLED) display panel, or a Mini Light Emitting Diodes (or Micro Light Emitting Diodes, MLED) display panel, etc.; the display panel 1000 can also be a passive light-emitting display panel, such as a Liquid Crystal Display (LCD) display panel, which is not limited herein in the present disclosure.

[0044] Exemplarily, as Figure 2 shown, the box body 10 includes a bottom plate 12 and a plurality of side plates 11, for example, four side plates 11, any two adjacent side plates 11 among the four side plates 11 are connected, the four side plates 11 are connected and enclosed and connected end to end, and the four side plates 11 are connected to the first surface 121 of the bottom plate 12, the four side plates 11 and the bottom plate 12 form a cavity A, and the curved inner lining 20 is placed in the cavity A.

[0045] Exemplarily, the bottom plate 12 and the plurality of side plates 11 of the box body 10 provide rigid protection to avoid damage to the display panel 1000 caused by external impacts. The shape, size, and the number of display panels 1000 loaded of the box body 10 can be designed and adjusted accordingly according to the actual size of the display panel 1000, which is not limited herein in the present disclosure.

[0046] Exemplarily, as Figure 3As shown, the first surface 21 of the curved inner lining 20 has a set curvature, and the set curvature of the first surface 21 of the curved inner lining 20 is consistent with the curvature of the assembled curved screen. It can be understood that the to-be-assembled curved screen has a set curvature. At this time, the display panel 1000 that makes up the curved screen also needs to have this set curvature. Similarly, the first surface 21 of the curved inner lining 20 on which the display panel 1000 is placed also has this set curvature.

[0047] Exemplarily, the surfaces of the box body 10 and / or the box cover 30 and / or the curved inner lining 20 can be engraved with marks, such as information indicating the production date of the box body 10, which set of molds is used for production, materials, the number of display panels 1000 transported, the curvature of the display panel 1000, etc.

[0048] Exemplarily, the box body 10, the curved inner lining 20, and the box cover 30 can all be foam-molded using polystyrene foam material or a polystyrene and polyethylene foam mixture or polypropylene foam material. The above materials are common foam materials, which have good cushioning performance while ensuring the support strength.

[0049] Exemplarily, as Figure 1 and Figure 3 shown, the first surface 21 of the curved inner lining 20 is a curved surface that bulges towards the second surface 22 of the curved inner lining 20. When the display panel 1000 is placed on the first surface 21 of the curved inner lining 20, based on the weight of the display panel 1000 itself, the display panel 1000 will form a curved surface with the same curvature as the first surface 21 of the curved inner lining 20 and also bulge towards the second surface 22 of the curved inner lining 20. This method relies on the self-weights of the curved inner lining 20 and the display panel 1000 to form the effect of placing the display panel 1000 in a curved shape, achieving the curved support for the display panel 1000. The display panel 1000 can be stacked and placed according to the set curvature and transported, ensuring that the display panel 1000 remains in a curved state from production to display screen assembly, effectively reducing the rebound stress of the display panel 1000 after display screen assembly, significantly improving the problem of light leakage, and solving the light leakage problem.

[0050] Exemplarily, curved display screens with different curvatures need to be assembled using display panels 1000 with corresponding curvatures. Display panels 1000 with different curvatures need to be packaged and transported using packaging boxes 100 with corresponding curvatures. Therefore, molds need to be separately opened for the production of packaging boxes 100 with different curvatures, resulting in high mold opening costs and long cycles.

[0051] Exemplarily, in the present application, the curved surface inner lining 20 and the box body 10 are designed separately, and only the curved surface inner linings 20 with different curvatures are molded and produced. One packaging box 100 is correspondingly equipped with a plurality of curved surface inner linings 20 with different curvatures. When it is necessary to package and transport a display panel 1000 with a certain curvature, the corresponding curvature of the curved surface inner lining 20 can be replaced only to achieve adaptation, which can greatly reduce the cost of opening molds and the mold opening cycle.

[0052] In some embodiments, as Figure 4 shown, the display panel 1000 includes a display main board 1001 and a circuit board 1002; as Figure 3 shown, the first surface 21 of the curved surface inner lining 20 includes a first part 211 and a second part 212. The first part 211 is used to place the display main board 1001, and the second part 212 is used to place the circuit board 1002. In the direction perpendicular to the second surface 22 of the curved surface inner lining 20, the average distance d1 between the second part 212 and the second surface 22 of the curved surface inner lining 20 is less than the average distance d2 between the first part 211 and the second surface 22 of the curved surface inner lining 20.

[0053] Exemplarily, as Figure 4 shown, the display panel 1000 includes a display main board 1001 and a circuit board 1002. The display main board 1001 and the circuit board 1002 are connected by a signal line 1003. The circuit board 1002 transmits an electrical signal to the display main board 1001 through the signal line 1003, which can be a control signal, for example, to control the display main board 1001 to display an image.

[0054] Exemplarily, the circuit board 1002 is relatively thick compared to the display main board 1001. When a plurality of display panels 1000 are stacked and placed in the packaging box 100, the thickness at the position of the stacked circuit boards 1002 is greater than the thickness at the position of the stacked display main boards 1001, that is, the stacked circuit boards 1002 are higher than the stacked display main boards 1001. It can be understood that when a plurality of display panels 1000 are stacked and placed in the packaging box 100, the display main boards 1001 of the plurality of display panels 1000 are stacked and placed corresponding to each other in the vertical direction, and the circuit boards 1002 of the plurality of display panels 1000 are stacked and placed corresponding to each other in the vertical direction. Since the stacked circuit boards 1002 are higher than the stacked display main boards 1001, during transportation, the signal line 1003 connecting the display main board 1001 and the circuit board 1002 is easily pulled and stressed, resulting in the breakage of the signal line 1003 and damage to the display panel 1000.

[0055] Exemplarily, in the direction perpendicular to the second surface 22 of the curved surface inner lining 20, as Figure 3As shown, the average distance d1 between the second part 212 of the first surface 21 of the curved surface lining 20 and the second surface 22 of the curved surface lining 20 is less than the average distance d2 between the first part 211 of the first surface 21 of the curved surface lining 20 and the second surface 22 of the curved surface lining 20. It can be understood that the first surface 21 of the curved surface lining 20 is a curved surface protruding towards the second surface 22 of the curved surface lining 20. That is to say, both the first part 211 and the second part 212 of the first surface 21 of the curved surface lining 20 are curved surfaces. Here, the "average distance" refers to: the average value of the distance from the highest point of the curved surface of the first part 211 of the first surface 21 of the curved surface lining 20 to the second surface 22 of the curved surface lining 20 and the distance from the lowest point to the second surface 22 of the curved surface lining 20, and the average value of the distance from the highest point of the curved surface of the second part 212 of the first surface 21 of the curved surface lining 20 to the second surface 22 of the curved surface lining 20 and the distance from the lowest point to the second surface 22 of the curved surface lining 20.

[0056] That is, as Figure 3 shown, the second part 212 of the first surface 21 of the curved surface lining 20 is integrally sunken relative to the first part 211. This setting makes the heights at the positions of the circuit boards 1002 and the display main boards 1001 of the uppermost display panel 1000 the same after multiple display panels 1000 are stacked in the packing box 100, which can effectively prevent the signal lines 1003 connecting the display main boards 1001 and the circuit boards 1002 from being pulled and stressed, prevent the signal lines 1003 from breaking, and ensure the quality of the display panels 1000.

[0057] In some embodiments, the lid 30 includes opposite first and second surfaces 31 and 32. The second surface 32 faces the outside of the packing box 100, and the first surface 31 faces the side of the box body 10; as Figure 5 shown, the lid 30 includes a first surface 31 close to the side of the box body 10. A curved surface limiting structure 1 is provided on the first surface 31 of the lid 30, and the surface of the curved surface limiting structure 1 is a curved surface protruding towards the box body 10.

[0058] In some embodiments, the surface of the curved surface limiting structure 1 has the same curvature as the first surface 21 of the curved surface lining 20.

[0059] Exemplarily, the protruding direction of the curved surface of the curved surface limiting structure 1 is consistent with the protruding direction of the curved surface of the first surface 21 of the curved surface lining 20, and the curvatures are the same. A space with a set curvature is formed between the curved surface limiting structure 1 provided on the first surface 31 of the box cover 30 and the first surface 21 of the curved surface lining 20. After stacking a set number of display panels 1000 on the first surface 21 of the curved surface lining 20, the box cover 30 is covered on the box body 10. The surface of the curved surface limiting structure 1 on the first surface 31 of the box cover 30 contacts the display panel 1000 stacked on the uppermost layer. Since the surface of the curved surface limiting structure 1 is a curved surface, a relatively large contact area with the display panel 1000 can be achieved, and the display panel 1000 is fixed in the direction perpendicular to the display panel 1000, realizing the vertical limiting of the display panel 1000, so that each part of the display panel 1000 is uniformly stressed during transportation, ensuring the safety of the display panel 1000 during transportation and guaranteeing the quality of the display panel 1000.

[0060] In some embodiments, as Figure 6 shown, the packaging box 100 for the display panel further includes a stopper group 40. The stopper group 40 includes a plurality of stoppers 41. As Figure 7 and Figure 8 shown, the stopper 41 includes a stopper fixing part 411 and a stopper limiting part 412; as Figure 2 shown, a plurality of stopper grooves 13 are further provided in the cavity A of the box body 10. The stopper grooves 13 are provided at the connection positions of adjacent two side plates 11. The plurality of stopper grooves 13 and the plurality of stoppers 41 are respectively arranged in correspondence. Referring to Figure 7 、 Figure 8 , the stopper fixing part 411 of the stopper 41 is engaged with the stopper groove 13; as Figure 9 shown, a plurality of lining stopper limiting grooves 221 are provided on the second surface 22 of the curved surface lining 20. The plurality of lining stopper limiting grooves 221 and the plurality of stoppers 41 are respectively arranged in correspondence. And referring to Figure 7 、 Figure 8 , the stopper limiting part 412 of the stopper 41 is engaged with the lining stopper limiting groove 221.

[0061] In some embodiments, the stopper limiting part 412 of the stopper 41 is higher than the first surface 21 of the curved surface lining 20.

[0062] Exemplarily, as Figure 6 shown, the stopper group 40 includes a plurality of stoppers 41, for example, four stoppers 41. As Figure 7 shown, Figure 7 schematically shows an exemplary structure of the stopper 41. The stopper 41 can be, for example, a plastic stopper 41-1. As Figure 8 shown, Figure 8Illustrate another exemplary structure of the stopper 41. For example, the stopper 41 can also be a foam stopper 41-2. Both the plastic stopper 41-1 and the foam stopper 41-2 include a stopper fixing portion 411 and a stopper limiting portion 412. The stopper fixing portion 411 is used to engage with the stopper groove 13 of the box body 10, thereby fixing the stopper 41 in the box body 10; the stopper limiting portion 412 is used to limit the curved surface lining 20 and the display panel 1000 to prevent the curved surface lining 20 and the display panel 1000 from sliding.

[0063] Exemplarily, as Figure 2 shown and referring to Figure 6 、 Figure 7 、 Figure 8 Among the multiple side plates 11 of the box body 10, for example, among the four side plates 11, adjacent two side plates 11 are connected, having four side plate connection positions. A stopper groove 13 can be provided at each connection position. It can be understood that one stopper groove 13 corresponds to one stopper 41, and the corresponding stopper groove 13 and stopper 41 are matched in shape and size. The stopper fixing portion 411 of the stopper 41 can be engaged in the stopper groove 13 of the box body 10, thereby fixing the stopper 41 in the box body 10 and preventing the stopper 41 from sliding.

[0064] For example, when the stopper 41 corresponding to the stopper groove 13 is a plastic stopper 41-1, the stopper groove 13 is the first stopper groove 13-1, and the stopper fixing portion 411 of the plastic stopper 41-1 can be engaged in the first stopper groove 13-1 of the box body 10; when the stopper 41 corresponding to the stopper groove 13 is a foam stopper 41-2, the stopper groove 13 is the second stopper groove 13-2, and the stopper fixing portion 411 of the foam stopper 41-2 can be engaged in the second stopper groove 13-2 of the box body 10.

[0065] Exemplarily, as Figure 9 shown and referring to Figure 6 、 Figure 7 、 Figure 8 On the second surface 22 of the curved surface lining 20, multiple, for example, four lining stopper limiting grooves 221 are provided. It can be understood that one lining stopper limiting groove 221 corresponds to one stopper 41, and the corresponding lining stopper limiting groove 221 and stopper 41 are matched in shape and size. The stopper limiting portion 412 of the stopper 41 can be engaged in the lining stopper limiting groove 221 of the curved surface lining 20, and the stopper limiting portion 412 is higher than the first surface 21 of the curved surface lining 20, thereby realizing the limitation of the curved surface lining 20 and the limitation of the display panel 1000 to be transported.

[0066] For example, when the stopper 41 corresponding to the inner liner stopper limiting groove 221 is the plastic stopper 41-1, the inner liner stopper limiting groove 221 is the first inner liner stopper limiting groove 221-1, and the stopper limiting portion 412 of the plastic stopper 41-1 can be engaged in the first inner liner stopper limiting groove 221-1; when the stopper 41 corresponding to the inner liner stopper limiting groove 221 is the foam stopper 41-2, the inner liner stopper limiting groove 221 is the second inner liner stopper limiting groove 221-2, and the stopper limiting portion 412 of the foam stopper 41-2 can be engaged in the second inner liner stopper limiting groove 221-2.

[0067] Exemplarily, the four stoppers 41 can all be plastic stoppers 41-1, or can all be foam stoppers 41-2, or can also be two plastic stoppers 41-1 and two foam stoppers 41-2. The present disclosure does not make a limitation herein.

[0068] Exemplarily, the material of the foam stopper 41-2 can be, for example, a polypropylene foam material, which has good cushioning performance while ensuring the support strength.

[0069] Exemplarily, the material of the plastic stopper 41-1 can be, for example, a thermoplastic polymer structural material or polycarbonate. Since the cushioning performance of the above materials is weak, therefore, as Figure 7 shown, a buffer strip 4121 can be attached to the stopper limiting portion 412 of the plastic stopper 41-1. The material of the buffer strip 4121 can be thermoplastic polyurethane elastomer rubber or thermoplastic elastomer material to ensure the cushioning performance of the stopper limiting portion 412 of the plastic stopper 41-1.

[0070] Exemplarily, the stopper fixing part 411 of the stopper 41 is engaged in the stopper groove 13 of the box body 10. The stopper groove 13 of the box body 10 limits the stopper 41, fixes the stopper 41 in the box body 10, prevents the stopper 41 from sliding, and ensures the accuracy of the stopper 41 in limiting the curved surface lining 20 and the display panel 1000. The stopper limiting part 412 of the stopper 41 is engaged in the lining stopper limiting groove 221 of the curved surface lining 20. Since the stopper 41 is fixed in the box body 10, the curved surface lining 20 is also fixed in the box body 10, realizing the limitation of the curved surface lining 20. By adjusting the thickness dimension of the stopper 41, a gap of 3 mm - 4 mm on one side of the display panel 1000 in the box body 10 can be achieved, preventing the display panel 1000 from colliding with the side plate 11 of the box body 10 during transportation and damaging the display panel 1000. The part of the stopper limiting part 412 of the stopper 41 that is higher than the first surface 21 of the curved surface lining 20 can limit the display panel 1000, preventing the display panel 1000 from moving in the horizontal direction and ensuring the stability of transportation. At the same time, the foamed stopper 41-2 has a buffering performance or a buffer strip 4121 is attached to the stopper limiting part 412 of the plastic stopper 41-1, so that the part of the stopper 41 that limits the display panel 1000 has a good buffering performance, preventing the display panel 1000 from colliding and causing defective fragments during transportation and ensuring the safety of the display panel 1000 during transportation.

[0071] Exemplarily, the stopper group 40 and the box body 10 are of a split design. When different-sized display panels 1000 need to be transported, only the stoppers 41 and the curved surface linings 20 of the corresponding sizes need to be replaced to achieve adaptation, which can greatly reduce the cost and cycle of mold opening.

[0072] In some embodiments, as Figure 2 shown, the box body 10 further includes a lining limiting structure 2 located in the cavity A. The lining limiting structure 2 is disposed on the first surface 121 of the bottom plate 12 and is connected to the first surface 121 of the bottom plate 12. As Figure 9 shown, the second surface 22 of the curved surface lining 20 is further provided with a limiting groove 222 corresponding to the lining limiting structure 2, and the lining limiting structure 2 is engaged with the limiting groove 222.

[0073] Exemplarily, in order to further limit the curved surface lining 20 in the horizontal direction and ensure the stability of the curved surface lining 20, as Figure 2 、 Figure 9 shown, a limiting groove 222 can be provided on the second surface 22 of the curved surface lining 20, and a lining limiting structure 2 can be provided on the first surface 121 of the bottom plate 12 of the box body 10, and the lining limiting structure 2 of the bottom plate 12 of the box body 10 is engaged in the limiting groove 222 of the curved surface lining 20.

[0074] Specifically, the inner lining limiting structure 2 may include two limiting blocks. The two limiting blocks are connected to the first surface 121 of the bottom plate 12 of the box body 10 and are respectively connected to the middle positions of two opposite side plates 11. Two limiting grooves with adapted dimensions are provided at the positions of the second surface 22 of the curved inner lining 20 corresponding to the two limiting blocks, and one limiting block is engaged in one limiting groove.

[0075] Exemplarily, the length, width, and height dimensions of the inner lining limiting structure 2 are designed and adjusted accordingly according to the actual size of the box body 10 and the thickness of the curved inner lining 20, and there are no fixed requirements.

[0076] In some embodiments, as Figure 2 shown, a hand-holding groove 14 is provided at the middle position of at least one side plate 11. In the direction perpendicular to the second surface 22 of the curved inner lining 20, the hand-holding groove 14 penetrates through the orthographic projection of the curved inner lining 20 on this side plate 11; as Figure 9 shown, an inner lining hand-holding groove 223 is provided at the position of the second surface 22 of the curved inner lining 20 corresponding to the hand-holding groove 14.

[0077] Exemplarily, in the direction perpendicular to the second surface 22 of the curved inner lining 20, the hand-holding groove 14 penetrates through the orthographic projection of the curved inner lining 20 on this side plate 11, that is, the dimension of the hand-holding groove 14 of the side plate 11 in the direction perpendicular to the second surface 22 of the curved inner lining 20 is greater than or equal to the thickness of the curved inner lining 20, and the side of the hand-holding groove 14 away from the bottom plate 12 of the box body 10 is higher than the first surface 21 of the curved inner lining 20 or is flush with the first surface 21 of the curved inner lining 20. This setting can ensure that the operator reaches into the hand-holding groove 14 of the side plate 11 of the box body 10 from the first surface 21 of the curved inner lining 20.

[0078] Exemplarily, the length, width, and height dimensions of the hand-holding groove 14 are designed and adjusted accordingly according to the actual size of the box body 10 and the thickness of the curved inner lining 20, and there are no fixed requirements.

[0079] Exemplarily, an inner lining hand-holding groove 223 is provided at the position of the second surface 22 of the curved inner lining 20 corresponding to the hand-holding groove 14. The hand-holding groove 14 of the side plate 11 of the box body 10 and the inner lining hand-holding groove 223 on the second surface of the curved inner lining 20 are correspondingly arranged. The operator can reach into the hand-holding groove 14 of the side plate 11 of the box body 10, and after reaching the inner lining hand-holding groove 223 on the second surface of the curved inner lining 20, tightly hold the inner lining hand-holding groove 223 to disassemble the curved inner lining 20; or tightly hold the inner lining hand-holding groove 223 and place the curved inner lining 20 into the box body 10 from the hand-holding groove 14 of the side plate 11 of the box body 10, so as to install the curved inner lining 20 in the box body 10. This setting can achieve the rapid installation or disassembly of the curved inner lining 20 and facilitate the replacement of the inner lining.

[0080] In some embodiments, as Figure 10As shown, the bottom plate 12 further includes a second surface 122 away from the plurality of side plates 11, and a box handle groove 1221 is provided at the edge of the second surface 122 of the bottom plate 12. This setting facilitates the handling of the packaging box 100.

[0081] In some embodiments, as Figure 10 shown, a reinforcing rib structure 3 is provided on the second surface 122 of the bottom plate 12, and the reinforcing rib structure 3 includes a plurality of hollow openings 3-1.

[0082] Exemplarily, a reinforcing rib structure 3 may be provided on the second surface 122 of the bottom plate 12 of the box body 10. The reinforcing rib structure 3 is a plate-like structure, which can improve the overall anti-deformation ability. The reinforcing rib structure 3 is provided with a plurality of hollow openings 3-1, which can reduce the material usage and save costs. The shape of the hollow openings 3-1 is not fixedly required.

[0083] In some embodiments, as Figure 11 shown, and with reference to Figure 10 , the box cover 30 further includes a second surface 32 away from the side of the box body 10. At least one protruding structure 4 is provided on the second surface 32 of the box cover 30, and the protruding structure 4 is dimensionally matched with the hollow opening 3-1. The protruding structure 4 has the same shape and is dimensionally matched with the corresponding hollow opening 3-1, and the protruding structure 4 corresponds to the position of the corresponding hollow opening 3-1. When stacking the packaging boxes 100, the protruding structure 4 on the second surface 32 of the box cover 30 stacked below is engaged in the hollow opening 3-1 of the reinforcing rib structure 3 of the bottom plate 12 of the box body 10 arranged above, so that two adjacent packaging boxes 100 in the direction perpendicular to the packaging box 100 are relatively fixed, preventing the packaging box 100 from sliding or shifting during transportation and causing damage to the display panel 1000 inside the packaging box 100.

[0084] In some embodiments, as Figure 2 shown, the box body 10 includes a plurality of connecting corners 15. The connecting corners 15 are the joints of two adjacent side plates 11, and the shape of the outer surface of one connecting corner 15 is different from the shape of the outer surfaces of the other connecting corners 15; as Figure 5 shown, the box cover 30 includes a plurality of top corners 33. One top corner 33 of the box cover 30 corresponds to one connecting corner 15 of the box body 10, and the shape of the outer surface of the top corner 33 of the box cover 30 is the same as the shape of the outer surface of the corresponding connecting corner 15 of the box body 10.

[0085] Exemplarily, as Figure 2As shown, among the multiple side plates 11 of the box body 10, for example, among the four side plates 11, two adjacent side plates 11 are connected to form four connection corners 15. The shape of the outer surface of one of the connection corners 15 can be, for example, a straight surface. The outer surface of this connection corner 15 and the side plate 11 of the box body 10 form a sharp obtuse angle. The shapes of the outer surfaces of the other three connection corners 15 can be, for example, arc surfaces. The outer surfaces of these three connection corners 15 and the side plate 11 of the box body 10 form arc chamfers. This setting constitutes the anti-misassembly structure of the box body 10.

[0086] Exemplarily, as Figure 5 shown, the box cover 30 includes four top corners 33 corresponding to the four connection corners 15 of the box body 10. The shape of the outer surface of the top corner 33 of the box cover 30 is the same as the shape of the outer surface of the corresponding connection corner 15 of the box body 10. That is, the shape of the outer surface of one of the top corners 33 is a straight surface. The outer surface of this top corner 33 and the side of the box cover 30 form a sharp obtuse angle. The shapes of the outer surfaces of the other three top corners 33 are arc surfaces. The outer surfaces of these three top corners 33 and the side of the box cover 30 form arc chamfers. Since the shape of the outer surface of one connection corner 15 of the box body 10 is different from the shapes of the outer surfaces of the other connection corners 15, the shape of the outer surface of one top corner 33 of the box cover 30 is different from the shapes of the outer surfaces of the other top corners 33. One top corner 33 of the box cover 30 can only be snapped onto the connection corner 15 of the box body 10 with the same shape as it. Therefore, the box cover 30 and the box body 10 form an anti-misassembly structure, and the box cover 30 can only be snapped onto the upper part of the box body 10 in one direction, ensuring the stability of the packaging box 100.

[0087] In some embodiments, as Figure 2 shown, a desiccant groove 16 is provided on at least one side plate 11. A desiccant is placed in the desiccant groove 16 to ensure that the water vapor inside the packaging box 100 is constant during transportation and prevent water vapor from invading the display panel 1000 and causing damage.

[0088] Exemplarily, as Figure 12 shown, when placing the display panel 1000 in the packaging box 100, place the gasket 5 on the first surface 21 of the curved inner lining 20 inside the box body 10; place the display panel 1000 above the gasket 5; place the gasket 5 above the display panel 1000 again; repeat the steps of alternately placing the gasket 5 and the display panel 1000 until the number of display panels 1000 reaches the set number. If the packaging box 100 can accommodate n display panels 1000, the number of gaskets 5 is n + 1; cover the box cover 30 above the box body 10 with the first surface 31 of the box cover 30 facing the side where the box body 10 is located. The overall steps of placing the display panel 1000 are simple and easy to operate.

[0089] The display panels 1000 are spaced apart by spacers 5 to prevent the display panels 1000 from being broken or scratched during packing and transportation.

[0090] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any one or more embodiments or examples in a suitable manner.

[0091] As mentioned above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure, thinking of changes or substitutions, should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
