[0041] 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.

[0042] Unless otherwise required by the context, throughout the specification and claims, the term "comprising" is interpreted in an open, inclusive sense, that is, "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 specific features, structures, materials, or characteristics related to the embodiment or example are included in at least one embodiment or example of the present disclosure. The above-mentioned schematic representations do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials, or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0043] When describing some embodiments, the expression "connected" and its 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 integrated; it may be directly connected, or indirectly connected through an intermediate medium. The embodiments disclosed herein are not necessarily limited to the content herein.

[0044] "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.

[0045] As used herein, "parallel", "perpendicular", and "equal" include the stated cases as well as cases similar to the stated cases, where the range of such similar cases is within an acceptable deviation range, and the acceptable deviation range is determined by one 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, within a deviation of 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, within a deviation of 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 ones is less than or equal to 5% of either one of them.

[0046] 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. Thus, variations in the shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Accordingly, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but include shape deviations caused by, for example, 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.

[0047] During the transportation of a display panel, it is necessary to place the display panel in a packaging box to avoid damage to the display panel during transportation. As the size of the display panel increases, the packaging requirements for the display panel during transportation become higher. In some embodiments, such as Figure 1 , Figure 2As shown in the figure, a limiting structure 1 is provided on the side wall 11 of the box body 10 of the packing box 100 of the display panel, realizing the horizontal limitation of the display panel and preventing the display panel from horizontally moving left and right in the packing box 100; the upper cover 20 of the packing box 100 can be used to realize the vertical limitation of the display panel and prevent the display panel from vertically moving up and down in the packing box 100; when the packing box 100 is filled with display panels, the vertical direction in the packing box 100 is filled, and the upper cover 20 of the packing box 100 contacts the uppermost display panel, which can limit the display panel in the vertical direction and prevent the display panel from vertically moving up and down; however, when the packing box 100 is not filled with display panels, the upper cover 20 of the packing box 100 fails to contact the uppermost display panel, and there is a gap between the uppermost display panel and the upper cover 20 of the packing box 100. During the process of handling the display panel, it is easy for the display panel to move in the vertical direction, resulting in cracks or breakage of the display panel, which not only affects the quality of the display panel but also increases the production cost.

[0048] In some embodiments, the present application provides a packing box 100 for a display panel, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14A 、 Figure 15 shown, the packing box 100 includes a box body 10, at least one limiting block 30, and an upper cover 20; the box body 10 includes a plurality of side walls 11 and a bottom wall 12, the plurality of side walls 11 are located on the same side of the bottom wall 12 and are respectively connected to the bottom wall 12, and adjacent two side walls 11 are connected. The plurality of side walls 11 and the bottom wall 12 form a cavity A, and at least one support limiting groove 111 is provided on the inner surface of at least one side wall 11; the limiting block 30 includes a connecting edge support 31 and a blocking block 32, the edge support 31 is configured to be capable of being engaged with the support limiting groove 111, the blocking block 32 includes a first surface a close to the bottom wall 12, and the distance between the first surface a of the blocking block 32 and the bottom wall 12 can be adjusted; the upper cover 20 is provided on the side of the plurality of side walls 11 away from the bottom wall 12, and the upper cover 20 is configured to be connected to the box body 10.

[0049] Exemplarily, the display panel is used to display an image; in terms of the light-emitting type of the display panel, the display panel may 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 may 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.

[0050] Exemplarily, as Figure 4 shown, the box body 10 includes a plurality of side walls 11, for example, four side walls 11 and a bottom wall 12. On the four side walls 11 of the box body 10, a bracket limiting groove 111 may be provided only on the surface of one of the side walls 11 on the side close to the cavity A, or on the surfaces of two or three or four side walls 11 on the side located in the cavity A; the number of bracket limiting grooves 111 on one side wall 11 can be set according to actual conditions, which is not limited herein in the present disclosure.

[0051] Exemplarily, as Figure 3 shown and referring to Figure 4 , Figure 5 , a limiting block 30 is correspondingly provided for one bracket limiting groove 111. The edge-blocking bracket 31 of the limiting block 30 can, for example, be vertically inserted into the bracket limiting groove 111 of the box body 10. After insertion, the edge-blocking bracket 31 can be engaged in the bracket limiting groove 111 to limit the limiting block 30 and prevent the limiting block 30 from moving relative to the box body 10.

[0052] It should be noted that the above "the edge-blocking bracket 31 is configured to be able to be engaged with the bracket limiting groove 111" means that at least a part of the edge-blocking bracket 31 can be embedded in the bracket limiting groove 111 and can be taken out from the bracket limiting groove 111. When the two are in the engaged state, the distance between the first surface a of the block 32 and the bottom wall 12 can be adjusted.

[0053] Exemplarily, the edge-blocking bracket 31 of the limiting block 30 is connected to the block 32. For example, the edge-blocking bracket 31 and the block 32 can be movably connected or fixedly connected.

[0054] Exemplarily, the display panels are stacked and placed in the packing box 100, and the first surface a of the stopper 32 close to the bottom wall 12 contacts the surface of the uppermost display panel. In some embodiments, the first surface a of the stopper 32 that directly contacts the surface of the uppermost display panel in the packing box 100 is a flat surface, and the first surface a of the stopper 32 fits with the surface of the uppermost display panel in the packing box 100; in other embodiments, as Figure 5 shown and with reference to Figure 10 , a buffer protection structure 2 is provided on the first surface a of the stopper 32, and the buffer protection structure 2 is detachably connected to the first surface a of the stopper 32; for example, at least one buffer limiting groove 322 is provided on the first surface a of the stopper 32, and at least one buffer limiting structure 2-1 is correspondingly provided on one side surface of the buffer protection structure 2, and the other side surface is a flat surface. The buffer limiting structure 2-1 of the buffer protection structure 2 can be engaged in the buffer limiting groove 322 on the first surface a of the stopper 32 to detachably connect the buffer protection structure 2 to the first surface a of the stopper 32, and the side surface where the flat surface is located in the buffer protection structure 2 contacts the surface of the uppermost display panel in the packing box 100; alternatively, a pasting structure is provided on both the first surface a of the stopper 32 and one side surface of the buffer protection structure 2, and the buffer protection structure 2 is pasted on the first surface a of the stopper 32 through the pasting structure, and the other side surface of the buffer protection structure 2 is a flat surface, and the side surface where the flat surface is located in the buffer protection structure 2 contacts the surface of the uppermost display panel in the packing box 100.

[0055] The corresponding setting here means that: the shapes, sizes, dimensions, and positions of the buffer limiting groove 322 and the buffer limiting structure 2-1 engaged in the buffer limiting groove 322 match each other.

[0056] Exemplarily, the buffer protection structure 2 is made of a special material, and its hardness is lower than that of the stopper 32, which can be used to protect the display panel from being scratched by the harder stopper 32.

[0057] Exemplarily, the distance between the first surface a of the stopper 32 in the limit stopper 30 and the bottom wall 12 of the box body 10 can be adjusted according to the actual number of display panels to be transported, so that the first surface a of the stopper 32 contacts the surface of the uppermost display panel in the stacked display panels, for example, fits with the edge of the surface of the uppermost display panel, realizing precise limitation of the display panel in the vertical direction.

[0058] Exemplarily, the display panels are stacked and placed in the packing box 100; the first surface a of the stopper 32 close to the bottom wall 12 contacts the surface of the uppermost display panel to limit the stacked display panels in the vertical direction; since the distance between the first surface a of the stopper 32 and the bottom wall 12 can be adjusted, it is possible to limit different numbers of stacked display panels in the vertical direction; this setting can prevent the display panels from moving up and down during transportation, thereby avoiding cracks or breakage of the display panels during transportation, reducing the transportation damage rate of the display panels, improving the transportation efficiency of the display panels, reducing the cost waste during transportation, and improving the quality of the display panels; and the packing box 100 of the present application is simple to operate, has strong flexibility, and can be compatible with the existing packing box 100.

[0059] Some possible implementation manners of the bracket limiting groove 111 and the limiting stopper 30 are introduced below.

[0060] In some embodiments, an exemplary structure of the limiting stopper 30 is introduced below, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 shown, and with reference to Figure 3 , the edge bracket 31 is engaged with the bracket limiting groove 111; at least one stopper limiting groove 311 is provided on the surface of the edge bracket 31 connected to the stopper 32, and the extending direction of at least one stopper limiting groove 311 is perpendicular to the bottom wall 12, for example, at least one stopper limiting groove 311 penetrates the edge bracket 31 in the direction perpendicular to the bottom wall 12; on the surface of the stopper 32 connected to the edge bracket 31, at least one stopper limiting structure 321 corresponding to at least one stopper limiting groove 311 is provided, and the stopper limiting structure 321 is configured to be able to be engaged in the stopper limiting groove 311 and be able to move relatively in the stopper limiting groove 311.

[0061] It should be noted that the structural descriptions of the edge bracket 31 and the stopper 32 are described in a state where the edge bracket 31 is engaged with the bracket limiting groove 111 and the distance between the first surface a of the stopper 32 and the bottom wall 12 can be adjusted.

[0062] Exemplarily, the shape of the stopper 32 can be, for example, a cuboid, a cube, etc., and the present application does not make a limitation here. In the present application, the stopper 32 is taken as a cuboid for illustration. When the stopper 32 is a cuboid, the first surface a of the stopper 32 is a rectangle, and the first surface a of the stopper 32 can be in full contact with the display panel, and the contact area between the two is relatively large, avoiding damage to the display panel due to too small contact area between the stopper 32 and the display panel.

[0063] Exemplarily, such as Figure 5As shown and with reference to Figure 3 , Figure 6 , Figure 8 , Figure 9 , the edge guard bracket 31 is movably connected to the stopper 32. The dimension b1 of the edge guard bracket 31 in the direction perpendicular to the bottom wall 12 can be greater than the dimension b2 of the stopper 32 in the direction perpendicular to the bottom wall 12. Two stopper limiting grooves 311 are provided on the surface of the edge guard bracket 31 at the connection position with the stopper 32. The orthographic projection of the two stopper limiting grooves 311 on the bottom wall 12 can be L-shaped, for example. The stopper limiting grooves 311 are used to connect with the stopper 32. The two stopper limiting grooves 311 penetrate the edge guard bracket 31 in the direction perpendicular to the bottom wall 12 so that the stopper 32 can move relative to each other within the stopper limiting grooves 311.

[0064] Exemplarily, as Figure 5 shown and with reference to Figure 3 , Figure 7 , Figure 8 , Figure 9 , two stopper limiting structures 321 are provided on the surface of the stopper 32 at the connection position with the edge guard bracket 31. The stopper limiting structures 321 are arranged corresponding to the stopper limiting grooves 311. The corresponding arrangement here means that the shapes, sizes, dimensions, and positions of the stopper limiting structures 321 and the stopper limiting grooves 311 match each other. One stopper limiting structure 321 is inserted into one stopper limiting groove 311 and moves in the direction perpendicular to the bottom wall 12 within the stopper limiting groove 311.

[0065] Exemplarily, in some embodiments, the connection position between the edge guard bracket 31 of the limit stopper 30 and the stopper 32 is an interference fit, that is, the stopper limiting structure 321 of the stopper 32 is inserted into the stopper limiting groove 311 of the edge guard bracket 31 and meets certain frictional resistance requirements, so that the stopper limiting structure 321 needs to be under the action of an external force to slide in the direction perpendicular to the bottom wall 12 within the stopper limiting groove 311; in the absence of an external force, due to the certain frictional resistance between the stopper limiting structure 321 and the stopper limiting groove 311, the stopper limiting structure 321 will not slide in the direction perpendicular to the bottom wall 12 within the stopper limiting groove 311. This setting can adjust the distance between the first surface a of the stopper 32 and the bottom wall 12 as needed, more precisely limit the display panel in the vertical direction; and avoid the weight of the stopper 32 applying a force to the display panel in the vertical direction, thereby damaging the display panel.

[0066] In some other embodiments, the following introduces another exemplary structure of the limit stopper 30, as Figure 11 shown and with reference to Figure 3, the stopper 32 includes a first stopper 32-1 and at least one second stopper 32-2 connected to the side of the first stopper 32-1 close to the bottom wall 12. The first stopper 32-1 is connected to the stopper edge bracket 31, and the stopper edge bracket 31 is engaged with the bracket limit groove 111; at least one second stopper 32-2 is configured to adjust the dimension of the stopper 32 in the direction perpendicular to the bottom wall 12.

[0067] Exemplarily, as Figure 11 shown, and referring to Figure 3 , the stopper edge bracket 31 is fixedly connected to the stopper 32. The dimension b1 of the stopper edge bracket 31 in the direction perpendicular to the bottom wall 12 can be greater than the dimension b2 of the stopper 32 in the direction perpendicular to the bottom wall 12; the first stopper 32-1 can be connected to the side of the stopper edge bracket 31 away from the bottom wall 12, for example; the first stopper 32-1 is fixedly connected to the stopper edge bracket 31, and can be integrally arranged, for example; the second stopper 32-2 of the stopper 32 is detachably connected to the first stopper 32-1.

[0068] Exemplarily, as Figure 11 shown, and referring to Figure 3 , when there is one second stopper 32-2 connected to the side of the first stopper 32-1 close to the bottom wall 12, a first limit groove 32-11 can be provided on the surface of the first stopper 32-1 close to the bottom wall 12, and a first limit structure 32-21 can be provided on one surface of the second stopper 32-2. The first limit structure 32-21 can be engaged with the first limit groove 32-11, and the other surface of the second stopper 32-2 serves as the first surface a of the stopper 32; alternatively, a pasting structure can be provided on the surface of the first stopper 32-1 close to the bottom wall 12 and one surface of the second stopper 32-2, and the second stopper 32-2 is detachably pasted to the surface of the first stopper 32-1 close to the bottom wall 12 through the pasting structure, and the other surface of the second stopper 32-2 serves as the first surface a of the stopper 32.

[0069] Exemplarily, when there are multiple second stoppers 32-2 connected to the side of the first stopper close to the bottom wall 12, the second stoppers 32-2 in the middle part can also be detachably connected by setting the connection method of the limit groove and the limit structure, or can be detachably connected by setting the connection method of the pasting structure, which will not be elaborated here.

[0070] Exemplarily, the size of the stopper 32 in the direction perpendicular to the bottom wall 12 can be adjusted by detachably connecting different numbers of second stoppers 32-2 to the surface of the first stopper 32-1 close to the bottom wall 12. Since the first stopper 32-1 is fixedly arranged on the edge bracket 31, adjusting the size of the stopper 32 in the direction perpendicular to the bottom wall 12 is to adjust the distance between the first surface a of the stopper 32 and the bottom wall 12. The distance between the first surface a of the stopper 32 in the limit stopper 30 and the bottom wall 12 of the box body 10 can be adjusted according to the number of display panels actually transported, so as to achieve precise limiting of the display panel in the vertical direction.

[0071] In some other embodiments, another exemplary structure of the limit stopper 30 is introduced below. As Figure 12 , Figure 13 shown, the edge bracket 31 is engaged with the bracket limit groove 111; the size x of the bracket limit groove 111 in the direction perpendicular to the bottom wall 12 is greater than the size b1 of the edge bracket 31 in the direction perpendicular to the bottom wall 12. When the edge bracket 31 is engaged with the bracket limit groove 111 and the distance between the first surface a of the stopper 32 and the bottom wall 12 can be adjusted, referring to Figure 13 the two limit stoppers 30 on the left side in, the edge bracket 31 is further configured to be able to move relatively in the direction perpendicular to the bottom wall 12 within the bracket limit groove 111 to drive the stopper 32 to move.

[0072] Exemplarily, as Figure 12 , Figure 13 shown, the size b1 of the edge bracket 31 in the direction perpendicular to the bottom wall 12 can be equal to the size b2 of the stopper 32 in the direction perpendicular to the bottom wall 12; it can also be greater than the size b2 of the stopper 32 in the direction perpendicular to the bottom wall 12, or less than the size b2 of the stopper 32 in the direction perpendicular to the bottom wall 12. The present disclosure does not make a limitation. In any of the above cases, the edge bracket 31 can move relatively in the direction perpendicular to the bottom wall 12 within the bracket limit groove 111. In this application, the size of the edge bracket 31 in the direction perpendicular to the bottom wall 12 is equal to the size of the stopper 32 in the direction perpendicular to the bottom wall 12 for illustration.

[0073] Exemplarily, as Figure 12 shown, the edge bracket 31 and the stopper 32 can be integrally provided.

[0074] Exemplarily, when using the limit stopper 30 to limit the display panel in the vertical direction, as Figure 13 shown in the left part in, and referring to Figure 12, the edge retaining bracket 31 of the limit stop 30 is engaged in the bracket limit groove 111 of the box body 10 and slides relatively in the direction perpendicular to the bottom wall 12 in the bracket limit groove 111, thereby driving the block 32 integrally provided therewith to move in the direction perpendicular to the bottom wall 12, realizing the limit of the display panel in the vertical direction.

[0075] Exemplarily, in some embodiments, the connection position between the edge retaining bracket 31 of the limit stop 30 and the bracket limit groove 111 is an interference fit, that is, the edge retaining bracket 31 is inserted into the bracket limit groove 111 and meets certain frictional resistance requirements, so that the edge retaining bracket 31 needs to slide in the direction perpendicular to the bottom wall 12 in the bracket limit groove 111 under the action of an external force; in the absence of an external force, due to the certain frictional resistance between the edge retaining bracket 31 and the bracket limit groove 111, the edge retaining bracket 31 will not slide in the direction perpendicular to the bottom wall 12 in the bracket limit groove 111. This setting can adjust the distance between the first surface a of the block 32 and the bottom wall 12 as needed, more accurately limit the display panel in the vertical direction; and avoid the weight of the limit stop 30 exerting a force on the display panel in the vertical direction, thereby damaging the display panel.

[0076] In some embodiments, such as Figure 12 , Figure 13 As shown, the limit stop 30 includes a first surface 30-1 and a second surface 30-2 oppositely arranged in the thickness direction Z, a first side surface 30-3 and a second side surface 30-4 oppositely arranged in the connection direction X of the edge retaining bracket 31 and the block 32, and a third side surface 30-5 and a fourth side surface 30-6 oppositely arranged in the direction Y perpendicular to the thickness direction Z and perpendicular to the connection direction X of the edge retaining bracket 31 and the block 32; the distance b1 / b2 between the first surface 30-1 and the second surface 30-2 is less than or equal to the dimension z of the bracket limit groove 111 in the direction perpendicular to its side wall 11; the distance c between the first side surface 30-3 and the second side surface 30-4 is less than or equal to the dimension x of the bracket limit groove 111 in the direction perpendicular to the bottom wall 12; the maximum distance d between the third side surface 30-5 and the fourth side surface 30-6 is less than or equal to the dimension y of the bracket limit groove 111 in the direction parallel to its side wall 11 and parallel to the bottom wall 12; the limit stop 30 is configured to be capable of being placed in the bracket limit groove 111.

[0077] In some embodiments, such as Figure 12 As shown, the edge retaining bracket 31 and the block 32 are mirror-symmetrical and integrally provided, and the limit stop 30 has a "worker"-shaped three-dimensional structure.

[0078] In some other embodiments, the overall size of the edge stop bracket 31 is larger than that of the stop block 32. When the limit stop 30 is used to limit the display panel in the vertical direction, the edge stop bracket 31 can be engaged in the bracket limit slot 111 and can slide relative to the bracket limit slot 111 in a direction perpendicular to the bottom wall 12. When the limit stop 30 is not needed, the entire edge stop bracket 31 and the stop block 32 can be placed in the bracket limit slot 111.

[0079] Exemplarily, a buffer protection structure 2 can be provided on the first surface a of the stop block 32 or the entire limit stop 30 can be made of a material with buffering performance to protect the display panel from damage.

[0080] Exemplarily, this setting can enhance the integration of the limit stop 30 and the box body 10. When it is not necessary to fix the display panel in the vertical direction, as Figure 13 shown in the right part, the limit stop 30 can be vertically placed in the bracket limit slot 111 on the side wall 11 of the box body 10 without affecting the supporting performance of the side wall 11 of the box body 10. When it is necessary to fix the display panel in the vertical direction, the limit stop 30 can be taken out from the bracket limit slot 111 on the side wall 11 of the box body 10, as Figure 13 shown in the left part, the edge stop bracket 31 of the limit stop 30 is engaged in the bracket limit slot 111, and the edge stop bracket 31 slides relative to the bracket limit slot 111 in a direction perpendicular to the bottom wall 12, thereby driving the stop block 32 integrally provided therewith to move in a direction perpendicular to the bottom wall 12.

[0081] When the limit stop 30 is not needed, the limit stop 30 can be completely placed in the bracket limit slot 111 on the side wall 11 of the box body 10 without separately providing a structure for storing the limit stop 30. The integrity between the limit stop 30 and the box body 10 is relatively high, which has high practicality and improves the convenience of use.

[0082] In some embodiments, in order to more conveniently pick up and place the limit stop 30, as Figure 13 shown and combined with Figure 12 , at least one handle groove 30-7 can be provided on the limit stop 30, and the handle groove 30-7 is provided on at least one of the first surface 30-1, the second surface 30-2, the first side surface 30-3 and the second side surface 30-4.

[0083] In some embodiments, as Figure 5 , Figure 6 shown and with reference to Figure 3 , Figure 4, the edge retaining bracket 31 includes a first bracket edge 31-1 and a second bracket edge 31-2. The second bracket edge 31-2 is vertically connected to the middle of the first bracket edge 31-1. The first bracket edge 31-1 and at least a part of the second bracket edge 31-2 are engaged with the bracket limiting groove 111 of the box body 10. The side of the second bracket edge 31-2 away from the first bracket edge 31-1 is connected to the stopper 32.

[0084] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 , Figure 11 shown, at least one triangular support member 312 is provided at the connecting position of the first bracket edge 31-1 and the second bracket edge 31-2 of the edge retaining bracket 31.

[0085] Exemplarily, the edge retaining bracket 31 has a "T"-shaped three-dimensional structure, which is simple in structure and convenient for engagement; and the structure of the bracket limiting groove 111 on the side wall 11 of the corresponding box body 10 is also relatively simple, which can simplify the manufacturing process. The triangular support member 312 makes the structure of the edge retaining bracket 31 stable and not easily deformed, ensuring the effectiveness of limiting the display panel in the vertical direction.

[0086] In some embodiments, the inside of the edge retaining bracket 31 is hollow, and the inside of the stopper 32 is hollow, which can effectively reduce the weight of the limiting stopper 30, thereby reducing the weight of the packaging box 100 and facilitating the handling of the packaging box 100.

[0087] In some embodiments, the following introduces another exemplary structure of the limiting stopper 30. As Figure 14A shown and referring to Figure 15 , the stopper 32 includes a horizontal portion 32-3 and a telescopic connection structure 32-4. The horizontal portion 32-3 is connected to one end of the telescopic connection structure 32-4, and the edge retaining bracket 31 is connected to the other end of the telescopic connection structure 32-4; the horizontal portion 32-3 is configured to be parallel to the bottom wall 12, and the telescopic connection structure 32-4 is configured to be able to telescopically move in a direction perpendicular to the bottom wall 12 so that the distance between the first surface a of the horizontal portion 32-3 close to the bottom wall 12 and the bottom wall 12 can be adjusted.

[0088] Exemplarily, as Figure 14B shown and referring to Figure 15, the first surface a of the stopper 32 is the side surface of the horizontal portion 32-3 close to the bottom wall 12. A buffer protection structure 2 can be provided on the side surface of the horizontal portion 32-3 close to the bottom wall 12. The side surface of the horizontal portion 32-3 close to the bottom wall 12, that is, the first surface a of the stopper 32, can have a relatively large area. Therefore, there is a relatively large contact area between the first surface a of the stopper 32 and the display panel, which is more conducive to limiting the display panel in the vertical direction and can prevent the stopper 32 from damaging the display panel.

[0089] Exemplarily, as Figure 14B shown, a buffer protection structure 2 can also be provided on the side of the telescopic connection structure 32-4 close to the horizontal portion 32-3 to prevent the display panel from being damaged by collision with the telescopic connection structure 32-4 during transportation.

[0090] Exemplarily, as Figure 14A , Figure 14B shown, and referring to Figure 15 , the edge blocking bracket 31 is connected to the side of the telescopic connection structure 32-4 away from the horizontal portion 32-3, that is, the limit stopper 30 has a "Z"-shaped three-dimensional structure, and the edge blocking bracket 31 is engaged with the bracket limit groove 111 on the side wall 11 of the box body 10 to limit the limit stopper 30.

[0091] Exemplarily, the telescopic connection structure 32-4 can be telescoped in the direction perpendicular to the bottom wall 12 to adjust the distance between the first surface a of the horizontal portion 32-3 close to the bottom wall 12 and the bottom wall 12.

[0092] In some embodiments, as Figure 16 , Figure 17 shown, and referring to Figure 15 , at least one groove 313 is provided on the side surface of the edge blocking bracket 31 away from the stopper 32, and a retractable clamping structure 3 that can extend outward relative to the groove 313 is provided in the groove 313; the retractable clamping structure 3 is configured to be able to engage with the bracket limit groove 111.

[0093] Exemplarily, a control switch 3-1 can be used to control the retractable clamping structure 3 to extend outward or retract into the groove 313 relative to the groove 313. When the limit stopper 30 needs to be used, place the groove 313 of the edge blocking bracket 31 at the position corresponding to the bracket limit groove 111 on the side wall 11 of the box body 10, slide the control switch 3-1 of the retractable clamping structure 3, and push the retractable clamping structure 3 out of the groove 313 of the edge blocking bracket 31 into the bracket limit groove 111 on the side wall 11 of the box body 10, so as to fix the relative position of the limit stopper 30 and the box body 10.

[0094] It can be understood that the display panel includes a display main board and a circuit board. The display main board and the circuit board are connected by signal lines. The circuit board transmits electrical signals, such as control signals, to the display main board through the signal lines, thereby controlling the display main board to display images. Since the circuit board is thicker and has a different size compared to the display main board, the sizes of the limit blocks for limiting the display main board and the limit blocks for limiting the circuit board will also be different. For example, considering the size gap between the edge of the circuit board and the edge of the display main board, the size of the limit block for limiting the display main board in the direction perpendicular to the side wall where the limit block is located is smaller than the size of the limit block for limiting the circuit board in the direction perpendicular to the side wall where the limit block is located.

[0095] In some embodiments, as Figure 18 shown, at least one upper cover limit block 21 is provided on the inner surface of the upper cover 20. The upper cover limit block 21 includes at least one sub-limit block 21-1 stacked thereon. At least one upper cover limit block 21 can be detachably connected to the upper cover 20, and adjacent sub-limit blocks 21-1 can be detachably connected.

[0096] Exemplarily, a bonding structure can be provided at the position where the upper cover limit block 21 is connected to the inner surface of the upper cover 20. A bonding structure can also be provided between multiple sub-limit blocks 21-1, so as to realize that at least one upper cover limit block 21 can be detachably connected to the upper cover 20, and adjacent sub-limit blocks 21-1 can be detachably connected.

[0097] Exemplarily, the sub-limit block 21-1 can be made of a material with good buffering performance. By adjusting the number of sub-limit blocks 21-1, the thickness of the upper cover limit block 21 in the vertical direction can be adjusted, so as to adjust the distance between the upper cover limit block 21 and the bottom wall 12, thereby realizing the limitation of the display panel in the vertical direction. When there is no need to limit the display panel in the vertical direction, the upper cover 20 does not need to add the upper cover limit block 21; when it is necessary to limit the display panel in the vertical direction, the upper cover limit block 21 can be fixed on the inner surface of the upper cover 20 through the bonding structure, and the number of upper cover limit blocks 21 can be increased according to actual needs to adjust the thickness of the upper cover limit block 21 in the vertical direction. This solution has a simple design and does not require changing the structure of the box body 10. Only the upper cover limit block 21 needs to be added to the inner surface of the upper cover 20.

[0098] The setting of the limit stop 30 in the box body 10 and the setting of the upper cover limit stop 21 on the inner surface of the upper cover 20 can be combined. For example, after limiting the vertical direction of the display panel by the limit stop 30, a certain number of upper cover limit stops 21 can also be provided on the inner surface of the upper cover 20 to double-limit the display panel, further ensuring that the display panel is not damaged during transportation.

[0099] In the description of this specification, the specific features, structures, materials, or characteristics may be combined in any one or more embodiments or examples in a suitable manner.

[0100] 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 by 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.
