[0046] like Figure 1 and Figure 2 As shown, this application provides a packaging box 100 for packaging a display device 200.

[0047] It should be noted that the display device 200 generally has a stand 50 and a screen assembly 60, the screen assembly 60 is connected with the stand 50, the stand 50 is used to be placed on the ground or a counter, thereby supporting the screen assembly 60, so that the screen assembly 60 has a certain height.

[0048] In some embodiments, as shown in Figures 1 to 3 The packaging box 100 includes a base assembly 10 and a cover 30, the base assembly 10 includes a first base 11 and a second base 12, in this embodiment, the base assembly 10 is divided into two parts according to the assembly sequence, the part assembled first is defined as the first base 11, and the part assembled later is defined as the second base 12. The first base 11 and the second base 12 are detachably connected. The first base 11 and the second base 12 can be connected together along the horizontal direction. Specifically, the first base 11 and the second base 12 can be connected together along the left-right direction or the front-rear direction; then the cover 30 is installed on the top of the first base 11 and the top of the second base 12 after being connected together, the cover 30 can be connected with at least one of the first base 11 and the second base 12, and the cover 30, the first base 11 and the second base 12 enclose a containing cavity, so that the screen assembly 60 is entirely accommodated in the containing cavity, thereby protecting the screen assembly 60, and this embodiment is described by taking the example of being connected together along the front-rear direction.

[0049] The first base 11 and the second base 12 jointly enclose an avoiding space 21, when the first base 11 and the second base 12 are assembled together based on the stand 50, part of the structure of the stand 50 passes through the avoiding space 21 and is exposed at the bottom of the first base 11 and the second base 12. When the first base 11 and the second base 12 are separated, at least one of the first base 11 and the second base 12 has an avoiding gap 22 corresponding to the position of the avoiding space 21, the avoiding gap 22 can be passed through by part of the structure of the stand 50 to separate from the avoiding space 21.

[0050] In the first example of the above embodiment, the first base 11 has the avoiding gap 22, before the packaging box 100 is assembled, the second base 12 is in a separated state from the first base 11, and the avoiding gap 22 of the first base 11 is exposed; thereby when the first base 11 is assembled based on the stand 50, part of the structure of the stand 50 can pass through and be placed in the avoiding gap 22; then the second base 12 is assembled, the second base 12 can close the avoiding gap 22 to form the avoiding space 21, thereby avoiding the stand 50 from the avoiding gap 22. When disassembled, the second base 12 is separated from the first base 11 by moving the second base 12, and the avoiding gap 22 of the first base 11 is exposed; at this time, the stand 50 can be moved out of the avoiding gap 22 by moving the first base 11.

[0051] In the second example of the above embodiment, the second base 12 has a clearance notch 22. After the first base 11 is assembled based on the frame 50, when the second base 12 is installed, the second base 12 is separated from the first base 11, and the clearance notch 22 of the second base 12 is exposed. By moving the second base 12 toward the first base 11, part of the structure of the frame 50 can pass through the clearance notch 22. After the second base 12 and the first base 11 are assembled in place, the first base 11 can close the clearance notch 22 to form a clearance space 21, and place part of the structure of the frame 50 in the clearance space 21. When disassembling, the frame 50 can also be moved out of the clearance notch 22 by moving the second base 12, and then the first base 11 and the frame 50 can be separated.

[0052] Of course, both the first base 11 and the second base 12 can have clearance notches 22, that is, the first example and the second example can be used together. In this case, the first base 11 and the second base 12 are connected, and the clearance notches 22 of the first base 11 and the clearance notches 22 of the second base 12 are arranged opposite to each other and enclose to form a clearance space 21.

[0053] When packaging the display device 200 using the packaging box 100 in this embodiment, it is not necessary to lift the display device 200 as a whole and move it into the receiving cavity of the packaging box 100. Instead, based on the frame 50 of the display device 200, the first base 11, the second base 12, and the cover 30 are assembled outside the screen assembly 60 of the display device 200. This makes the packaging process of the display device 200 more convenient and reduces the risk of damage to the display device 200. Furthermore, the first base 11 and the second base 12 of the packaging box 100 are detachably connected, enabling quick assembly and disassembly.

[0054] The first base 11 can move between a first state and a second state. When the first base 11 is in the first state, it is separated from the frame 50; when the first base 11 is in the second state, it is supported by the frame 50. The first base 11 can move from the first state to the second state for assembly. In the second state, the frame 50 supports the first base 11, so that after the screen assembly 60 of the display device 200 is assembled with the packaging box 100, the whole formed by the display device 200 and the packaging box 100 is supported by the frame 50.

[0055] Among them, such as Figure 2 As shown, the bottom of the first base 11 may have a first roller 113, which can contact the ground to facilitate moving the first base 11; when the first base 11 moves to the second state, the first roller 113 is disengaged from the ground.

[0056] In order to further reduce the assembly difficulty of the packaging box 100, as shown in Figure 2 , a guide portion 51 can be arranged on the frame 50 of the display device 200.

[0057] Correspondingly, as shown in Figure 2 , the first base 11 comprises a seat body 111 and a guide structure 112 connected with the seat body 111. When the first base 11 is in the first state, the guide structure 112 is separated from the guide portion 51; when the first base 11 is in the second state, as shown in Figure 4 and Figure 5 , the guide structure 112 is in movable contact with the guide portion 51, the guide structure 112 is supported on the guide portion 51 and the seat body 111 is lifted by a certain height compared with the first state. By cooperating the guide structure 112 with the guide portion 51, the relative position of the first base 11 and the frame 50 can be more conveniently adjusted, thereby reducing the assembly difficulty of the packaging box 100.

[0058] As shown in Figures 4 to 5 , the guide structure 112 comprises a mounting plate 1121 and a plurality of rolling members 1122, the mounting plate 1121 is connected with the seat body 111, and the plurality of rolling members 1122 are arranged at intervals along the first direction and are rotatably connected with the mounting plate 1121; the rolling members 1122 are at least partially exposed on the bottom surface of the mounting plate 1121 to be in rolling contact with the guide portion 51. The rolling members 1122 can be in rolling contact with the guide portion 51, thereby solving the problem of poor contact between the guide structure 112 and the guide portion 51 during movement. Through the rolling contact of the rolling members 1122, the guide structure 112 can move smoothly along the guide portion 51, reducing friction and resistance, and ensuring smooth movement of the guide structure 112.

[0059] The rolling members 1122 can be rollers, balls or other suitable rolling elements, and the material of the rolling members 1122 can be metal, plastic or rubber, etc., and the specific selection can be adjusted according to the actual use requirements. The number and interval of the rolling members 1122 can be designed according to the size and bearing requirement of the packaging box 100, to ensure the stability and smoothness of the guide structure 112 during movement.

[0060] As shown in Figure 2 and Figure 3As shown, when the first base 11 has a clearance notch 22 opening to the front, there are two guide structures 112. The two guide structures 112 are arranged opposite each other in the left and right directions and both extend in the front and back directions. The two guide structures 112 are arranged close to the two opposite edges of the clearance notch 22 in the left and right directions. When the first base 11 is in the second state, the two guide structures 112 can be tightly engaged with the two guide parts 51 on both sides of the frame 50 to form spaced support points, effectively preventing the base from shaking or tilting during movement and improving the stability and safety of the docking process. As the first base 11 moves, part of the frame 50 can be located within the clearance notch 22. After the first base 11 is moved into place, the second base 12 is assembled so that the second base 12 closes the clearance notch 22. The first base 11 and the second base 12 cooperate to form a complete outer edge, which is conducive to cooperating with the bottom edge of the cover 30 to protect the internal structure.

[0061] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, the first base 11 has a clearance notch 22 opening to the front. When the first base 11 is in the second state, the clearance notch 22 allows the frame 50 of the display device 200 to be placed within the clearance notch 22 during the movement of the first base 11. After the first base 11 is moved into place, the second base 12 can be disposed at the opening of the clearance notch 22 and detachably connected to the first base 11. There is a gap between the rear edge of the second base 12 and the inner wall of the clearance notch 22 to allow the bracket 53 to pass through.

[0062] The size of the gap between the second base 12 and the inner wall of the clearance notch 22 should be adjusted according to the size and shape of the rack 50 to ensure that the rack 50 can pass through smoothly and remain stable.

[0063] like Figure 3 and Figure 8 As shown, the second base 12 includes a plate 121 and two hanging ears 122. Both hanging ears 122 are connected to the plate 121, and each hanging ear 122 protrudes from both ends of the plate 121 along the second direction. The plate 121 is located at the clearance notch 22, thereby closing the opening of the clearance notch 22. The two hanging ears 122 can support the opposite two edges of the clearance notch 22 along the second direction, thereby connecting the second base 12 with the first base 11, increasing the stability and support of the second base 12 within the clearance notch 22, and enabling the second base 12 to be assembled more securely with the first base 11, avoiding the impact on the overall structural stability of the packaging box 100 and the protective effect of the display device 200 due to loosening or displacement.

[0064] The hanging lug 122 can be fixed to the top of the plate 121 by screws or other fasteners, facilitating the flush connection between the plate 121 and the bottom of the base 111. The hanging lug 122 can be designed as a frame structure to increase the extension length of the support point, thereby improving the strength of the connection point and dispersing the force. The second base 12 and the first base 11 can be detachably connected by a butterfly latch 43, which is located in the hollow area of ​​the frame structure. In this design, the hanging lug 122 bears the force, while the butterfly latch 43 only performs the locking function, which can avoid the problem of additional stress concentration caused by the latch providing support force and extend the service life of the packaging box 100.

[0065] In other embodiments, the ear 122 and the plate 121 may also be integrally formed; or the ear 122 and the plate 121 may be flush, and a limiting notch may be provided on the base 111, with the ear 122 installed in the limiting notch, thereby improving the accuracy of the installation position of the second base 12 and making it easier for the outer edges of the plate 121 and the base 111 to be flush. This application does not limit this.

[0066] The base 111 may consist only of the base plate 1111. Correspondingly, the plate 121 of the second base 12 consists only of the first plate 1211. The first plate 1211 is installed on the clearance notch 22. There is a gap between the rear end face of the first plate 1211 and the wall of the clearance notch 22. The front end face of the first plate 1211 and the outer edge of the base plate 1111 form a rectangular structure.

[0067] like Figures 7 to 9 As shown in the figure, the base 111 may also include a base plate 1111 and a side plate 1114. Correspondingly, the plate 121 of the second base 12 includes a first plate 1211 and a second plate 1212.

[0068] The outline of the base plate 1111 includes a first edge 1112 and a second edge 1113 that are adjacent to each other. The first edge 1112 forms a clearance notch 22, and the side plate 1114 is connected to the second edge 1113. That is, the side plate 1114 extends along the second edge 1113 and forms an opening structure at the position corresponding to the clearance notch 22. Specifically, the side plate 1114 includes a left side plate, a right side plate, a front side plate, and a rear side plate. The side plate 1114 forms two opposing first end faces 1115 at the clearance notch 22. Specifically, the front side plate includes two sub-plates that are spaced apart in the left-right direction. The space between them corresponds to the position of the clearance notch 22. That is, the opposing ends of the two sub-plates are flush with the edge of the clearance notch 22, and the opposing ends of the two sub-plates both form the first end face 1115.

[0069] The plate body 121 includes a first plate 1211 and a second plate 1212, the first plate 1211 is arranged at the avoiding gap 22, and the second plate 1212 is spliced on both sides along the second direction and corresponds to the two first end faces 1115 one by one; the left and right ends of the second plate 1212 are spliced with the two sub-plates, so as to fill the opening structure. The top of the side plate 1114 is flush with the top of the second plate 1212, so that the top of the side plate 1114 and the top of the second plate 1212 form a complete rectangular frame, thereby being used for connecting with the bottom of the cover shell 30, and only the part structure of the avoiding gap 22 at the bottom is communicated with the accommodating cavity and the avoiding space 21, so as to form a semi-closed space and protect the internal components.

[0070] The second plate 1212 and the first plate 1211 can be connected as an integral structure, so as to enhance the overall strength and stability of the plate body 121. The two hanging ears 122 are connected with the first plate 1211, and the second plate 1212 and the first plate 1211 are vertically arranged, so that the filling of the avoiding gap 22 and the opening structure can be realized at one time.

[0071] The first end face 1115 can form a guide groove 1116 extending in the vertical direction, and the left and right ends of the second plate 1212 can be provided with vertically extending guide protrusions 1213, the guide protrusions 1213 are arranged in the guide groove 1116 and slide along the guide groove 1116 until the hanging ears 122 are in contact with the bottom plate 1111, at this time, the second base 12 is installed in place. The cooperation of the guide groove 1116 and the guide protrusion 1213 realizes the limiting of the left-right direction and the front-rear direction, and also plays a guiding role, so as to facilitate the alignment of the second plate 1212 and the side plate 1114 and reduce the assembly error. The hanging ears 122 cooperate with the bottom plate 1111 to realize the limiting of the up-down direction, through the cooperation of the guide groove 1116 and the guide protrusion 1213 and the cooperation of the hanging ears 122 and the bottom plate 1111, the limiting and fixing in multiple directions are realized, so as to enhance the overall stability and reliability.

[0072] The top of the seat body 111 can be provided with a partition plate, and the partition plate and the side plate 1114 or the partition plate and the partition plate surround a storage groove, the storage groove can be used for placing related accessories or tools of the display device 200, such as a connecting line, a remote controller, a wrench and the like.

[0073] As Figure 1 , Figure 3 , Figure 10 and Figure 11As shown, the cover 30 comprises a first cover plate 31 and a second cover plate 32 which are detachably spliced, the first cover plate 31 is connected with the first base 11, and the second cover plate 32 is connected with one of the first base 11 and the plate body 121. Specifically, the bottom of the first cover plate 31 is connected with part of the structure of the top of the side plate 1114, and the bottom of the second cover plate 32 is connected with the rest of the structure of the top of the side plate 1114 and the top of the second plate 1212. The first cover plate 31 and the second cover plate 32, i.e., the front and rear two half shells, can be spliced from the front and rear sides of the display device 200 without being lifted as a whole to the top of the display device 200 and then being lowered, which can reduce the difficulty of packaging.

[0074] In some embodiments, the first cover plate 31 can comprise a complete rear cover plate and rear halves of a left cover plate, a top cover plate and a right cover plate, and the second cover plate 32 can comprise a complete front cover plate and front halves of a left cover plate, a top cover plate and a right cover plate, i.e., the first cover plate 31 and the second cover plate 32 can be symmetrically arranged. Of course, the dividing line between the front half and the rear half is not necessarily centered. Even the first cover plate 31 can comprise a rear cover plate, a left cover plate, a top cover plate and a right cover plate, and the second cover plate 32 comprises a front cover plate, which is not limited in the present application.

[0075] In other embodiments, the first cover plate 31 and the second cover plate 32 can be spliced along the left-right direction, which is not limited in the present application.

[0076] The edges of the first cover plate 31 and the edges of the second cover plate 32 can also be provided with interlocking toothed structures, thereby further improving the positional accuracy of the assembly of the first cover plate 31 and the second cover plate 32.

[0077] As shown in Figure 1 , Figure 10 and Figure 11 , the first base 11 and the second base 12, the first base 11 and the first cover plate 31, the first base 11 and the second cover plate 32, the second base 12 and the second cover plate 32, the first cover plate 31 and the second cover plate 32 can all be connected by using a butterfly-shaped lock 43, so that the packaging box 100 can be quickly disassembled without using tools.

[0078] It should be noted that in the second state, the first base 11 is in movable contact with the rack 50. That is, the first base 11 can move a distance. After the first base 11 is moved into position, the first base 11 can be limited by the rack 50, thereby improving the positional accuracy of the assembled packaging box 100 and the overall stability of the packaging box 100 and the display device 200.

[0079] In some embodiments, as shown in Figure 6 and Figure 9As shown, the packaging box 100 further comprises a limiting block 41 and a buffer block 42, both of which are connected with the first base 11. After the first base 11 is moved into position, the limiting block 41 can limit the support 53 to prevent relative shaking between the support 53 and the packaging box 100. The buffer block 42 can support the screen assembly 60 to better protect the screen assembly 60.

[0080] Specifically, the limiting block 41 has a limiting slot 411 opening towards the first direction, i.e. the limiting slot 411 opens forward, and the shape and size of the limiting slot 411 are designed according to the structure of the support 53. At least the rear wall surface of the limiting slot 411 is flush with the edge of the avoiding gap 22, so that when the guide structure 112 is moved to the preset position, the limiting slot 411 is used to limit the support 53. Specifically, part of the mechanism of the support 53 can be clamped into the limiting slot 411 and can be in contact with the rear wall surface and the left and right wall surfaces of the limiting slot 411. The rack 50 is tightly matched with the limiting slot 411, so that the rack 50 and the first base 11 can maintain a stable posture, effectively preventing the support 53 from shaking relative to the inside of the packaging box 100 due to vibration or impact during transportation, effectively ensuring the relative position of the packaging box 100 and the screen assembly 60, and avoiding damage to the screen assembly 60.

[0081] Specifically, the limiting block 41 can be in contact with the bottom edge of the screen assembly 60. Alternatively, a receiving groove is formed on the first base 11, the receiving groove is filled with foam, the limiting block 41 is located outside the receiving groove and close to the side wall of the receiving groove, the bottom edge of the screen assembly 60 is placed in the receiving groove and in contact with the foam, and the limiting block 41 is in contact with the frame structure 62 of the screen assembly 60 for connecting with the rack 50, so as to better protect the screen assembly 60.

[0082] The limiting block 41 and the buffer block 42 can be integrated into an integral structure, i.e. the buffer block 42 is located on the top of the limiting block 41. In this case, the buffer block 42 can support the structure of the screen assembly 60 and the support 53 for sliding fit. The limiting block 41 and the buffer block 42 can be made of flexible materials such as rubber, silicone, polyurethane, etc., so as to be able to produce certain deformation absorption and dispersion of force, avoid rigid collision with the support and the screen assembly of the display device, and avoid scratching and wearing of the support and the screen assembly.

[0083] In a second aspect, as Figure 12 shown, the application also provides a display device 200, as Figure 2 and Figure 12As shown, the display device 200 comprises a rack 50 and a screen assembly 60, the screen assembly 60 is connected with the rack 50, the rack 50 has a guide part 51; the guide part 51 can be movably connected with the guide structure 112 of the first base 11 and support the guide structure 112. When packaging the display device 200 in the embodiment, the guide part 51 is provided by the base 52 to cooperate with the guide structure 112 of the packaging box 100, and then the second base 12 and the cover 30 are assembled outside the support 53 and the screen assembly 60 of the display device 200, so that the packaging process of the display device 200 is more convenient, and the risk of damage of the display device 200 is reduced. The guide part 51 cooperates with the guide structure 112, which can better define the positional relationship between the display device 200 and the packaging box 100; and after assembly is completed, the display device 200 and the packaging box 100 as a whole are based on the rack 50 of the display device 200, which can improve the overall stability of the display device 200 and the packaging box 100.

[0084] Specifically, the rack 50 comprises a base 52 and a support 53, the support 53 is connected with the base 52, and the screen assembly 60 is slidably connected with the support 53 in the vertical direction; after the first base 11 is assembled in place, the screen assembly 60 can be slid downward to contact the first base 11 of the packaging box 100, so as to reduce the overall height after packaging.

[0085] As shown in Figure 6 and Figure 12 The screen assembly 60 can be formed by splicing a plurality of screen units 61, and the screen units 61 on the left and right sides can be folded towards the middle, thereby reducing the overall left-right size after packaging. The screen assembly 60 comprises a frame structure 62, and the frame structure 62 is slidably connected with the support 53. The entire screen assembly 60 can be supported by the contact between the frame structure 62 and the buffer block 42, thereby reducing the stress on the screen units 61.

[0086] The support 53 generally comprises two or more than two columns 531, and the limiting block 41 and the buffer block 42 in the packaging box 100 can be consistent in number with the columns 531.

[0087] Further, as shown in Figure 12 and Figure 13As shown, the guide part 51 comprises a first section 511 and a second section 512 connected with each other, the second section 512 is horizontally arranged, and the first section 511 is arranged to be inclined upward in the direction close to the second section 512. The first base 11 moves forward on the ground until the guide structure 112 moves to be in contact with the first section 511, so that the first base 11 is in the second state. The first base 11 continues to move forward, and when the guide structure 112 moves along the direction from the first section 511 to the second section 512, the inclined arrangement of the first section 511 can guide the moving direction of the guide structure 112, so that the first base 11 is lifted to be separated from the ground and is supported by the guide part 51 instead. Through the cooperation of the first section 511 and the second section 512, the guide part 51 can ensure the smooth transition of the guide structure 112 during the moving process, thereby reducing the difficulty of the packaging operation.

[0088] The guide part 51 can be concave to form a groove, and the rolling part 1122 of the guide structure 112 is in contact with the wall surface of the groove, which can prevent the guide structure 112 from deviating in the left-right direction during the moving process.

[0089] In some embodiments, the left and right sides of the base 52 are each provided with a guide part 51, which can be a guide plate extending in the front-rear direction, and the guide structure 112 can slide along the top surface of the guide plate. By separately arranging the guide plate, the surface of the base 52 can be prevented from being scratched and worn.

[0090] Specifically, as shown in Figure 5 The guide plate comprises a mounting part 513, a side blocking part 514 and a supporting part 515 connected with each other to form a U-shaped structure, and the U-shaped openings of the two guide plates are arranged to face away from each other. The mounting part 513 is connected with the bottom of the base 52 and is arranged close to the edge to facilitate the exposure of the supporting part 515. When the two guide structures 112 are in contact with the two supporting parts 515, the two side blocking plates can limit the left-right direction of the guide structure 112 to prevent the guide structure 112 from falling during the sliding process.

[0091] In other embodiments, the surface of the base 52 can also be arranged as the guide part 51, and the guide structure 112 of the first base 11 can directly cooperate with the surface of the base 52 to realize sliding, which is not limited in the present application.

[0092] As shown in Figure 12 and Figure 13 The bottom of the base 52 can be provided with a second roller 54, which is used to contact the ground to facilitate the pushing of the display device 200 or the pushing of the display device 200 and the packaging box 100 assembled based on the base 52 during the carrying.

[0093] According to some embodiments of the utility model, the utility model embodiments are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and within the knowledge range possessed by ordinary skilled in the art, various changes can be made without departing from the purpose of the utility model. In addition, the embodiments and the features in the embodiments of the utility model can be combined with each other without conflict.
