[0021] When the enclosure is closed to form a receiving space, the side wall of the socket is locked and limited in the limiting groove to prevent the tongue from falling off, thereby improving the connection strength and structural stability between the tongue and the side plate with the second end plate or the second end plate.

[0022] In some embodiments, in the third-party direction, the two narrow sidewalls of the tongue are recessed at the second pressure line with notches.

[0023] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0047] Typical embodiments embodying the features and advantages of this application will be described in detail in the following description. It should be understood that this application can have various variations in different embodiments, all of which do not depart from the scope of this application, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this application.

[0049] In related technologies, display devices are generally placed within a box-like packaging structure to facilitate their placement, storage, and transportation. The box-like packaging structure includes a lower box and an upper box nested within the lower box. Furthermore, for display devices of the same length, the width of the lower box varies depending on factors such as the size of the back cover, the size of the back cover, and related accessories of different models.

[0050] The lower cabinet has both a flat and an assembled state. When the lower cabinet is in the flat state, it is easy to stack and place, thus facilitating storage and transportation. After the lower cabinet is assembled and folded from its flat state, it is in the assembled state, used to house and limit the display device.

[0051] Figure 1 This is a structural schematic diagram of the lower housing of this utility model. Figure 2 This is a schematic diagram of the first structure of the lower box of this utility model when it is enclosed.

[0052] See Figure 1 and Figure 2 This application provides a boxed packaging structure for display devices, comprising a lower box and an upper box. The lower box can be used to package various display devices of the same length but different widths, thereby improving the versatility of the lower box and reducing its production and warehouse management costs.

[0053] In this embodiment, the display device can be a display screen, a flat-screen TV, or other similar device.

[0054] In other embodiments, the nesting packaging structure can be used not only for packaging display devices, but also for packaging various other items of the same length but different widths, such as air conditioners, refrigerators, and water heaters.

[0055] For ease of understanding and description, the following description refers to the state after the display device is packaged in a box. The length direction of the display device is taken as the first direction, the width direction of the display device is taken as the second direction, and the height direction of the display device is taken as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0056] See Figure 1 and Figure 2 In this embodiment, the packaging structure of the display device may include a lower box and an upper box nested inside the lower box. The lower box may include a bottom plate 100, two side plates 200, and an end plate 300. The bottom plate 100 is a rectangular structure. The two side plates 200 are disposed on both sides of the bottom plate 100 along a first direction. A bending portion 220 may be provided on the side of the side plate 200 near the bottom plate 100, and the bending portion 220 connects the side plate 200 and the bottom plate 100. A plurality of first pressure lines 221 spaced apart along the first direction may be formed on the bending portion 220. The first pressure lines 221 extend along a second direction, and the side plate 200 can be bent around any one of the first pressure lines 221 to adjust the spacing between the two side plates 200 in the first direction. The second direction is perpendicular to the first direction. The end plates 300 are disposed at both ends of the side plates 200 in the second direction, and the end plates 300 at the same end of the two side plates 200 are respectively a first end plate 310 and a second end plate 320.

[0057] When the two side plates 200 bend towards each other, the first end plate 310 and the second end plate 320 located at the same end can be attached to each other and limited, and the bottom plate 100, the two side plates 200 and the end plate 300 enclose and form an accommodating space with an opening on one side.

[0058] When the box is in use, the staff can bend the two side plates 200 along any of the first pressure lines 221 so that the bending parts 220 on the front and rear sides of the bottom plate 100 are bent, and the end plates 300 on the two side plates 200 are attached to each other and limited, so that the bottom plate 100, the two side plates 200 and the end plates 300 are enclosed to form an accommodating space.

[0059] Workers can selectively bend the side panels 200 around one of the first pressure lines 221 to adjust the width between the two side panels 200, thereby adjusting the width of the accommodating space. This allows the lower box to be used to package various display devices of the same length but different widths, improving the versatility of the box packaging structure and reducing the production and warehouse management costs of the box packaging structure.

[0060] In this embodiment, the base plate 100 can be a rectangular structure and extends along the second direction to fit the bottom of the display device.

[0061] Figure 3 yes Figure 2 Enlarged view of the structure at point A in the middle. Figure 4 This is a schematic diagram of the second structure of the lower box of this utility model when it is enclosed. Figure 5 yes Figure 4 Enlarged view of the structure at point B. Figure 6 This is a schematic diagram of the third structure when the lower box of this utility model is enclosed. Figure 7 yes Figure 6 Enlarged view of the structure at point C. Figure 8 This is a schematic diagram of the fourth structure when the lower box of this utility model is enclosed.

[0062] See Figure 1 , Figures 2 to 8 In this embodiment, the two side plates 200 can be respectively disposed on both sides of the base plate 100 along the first direction. A bending portion 220 can be provided on the side of the side plate 200 near the base plate 100, connecting the side plate 200 and the base plate 100. Multiple first pressure lines 221 spaced apart along the first direction can be formed on the bending portion 220. The first pressure lines 221 extend along a second direction, and the side plate 200 can be bent toward the base plate 100 around any one of the first pressure lines 221 to adjust the distance between the two side plates 200.

[0063] When packaging display devices, workers can selectively bend the side panels 200 along one of the first pressure lines 221 according to the width of the display device, so that the two side panels 200 can rotate towards each other to adjust the distance between the two side panels 200, so that the two side panels are attached and confined to the two sides of the display device. This allows for the packaging of various display devices with the same length but different widths, effectively improving the versatility of the lower box and reducing the production cost and warehouse management cost of the lower box.

[0064] Understandably, when the cabinet is in an assembled state to accommodate the display device, some of the first pressure lines can be spaced apart along a first direction, and / or, some of the first pressure lines can be spaced apart along a third direction. When the cabinet is in an unassembled and flat state, the multiple first pressure lines 221 are spaced apart along the first direction.

[0065] Understandably, foam can also be placed between the display device and the lower housing, and the two side panels 200 can rotate in opposite directions to fit against the sides of the foam, thereby enclosing and limiting the foam and the display device inside.

[0066] In some embodiments, the plurality of first pressure lines 221 may all be located on the same side of the third direction of the base plate 100, so that when the base plate 100, the two side plates 200 and the end plate 300 are enclosed to form an accommodating space, the plurality of first pressure lines 221 are all located inside the accommodating space, so that the two side plates 200 can be bent toward each other.

[0067] In some embodiments, a first fixing hole 210 may be provided on the side plate 200. The first fixing hole 210 is used to accommodate and limit the foam and / or display device, so as to improve the connection strength and structural stability between the lower housing and the display device.

[0068] In other embodiments, there may be multiple first fixing holes 210, which are arranged at intervals along the second direction on the side plate 200 to improve the connection strength and structural stability between the lower housing and the display device.

[0069] In some embodiments, the two bends 220 may be symmetrically arranged with respect to the center line of the base plate 100, so that the plurality of first pressure lines 221 in the two bends 220 are symmetrically arranged with respect to the center line of the base plate 100.

[0070] Workers can bend the side plate 200 along one of the first pressure lines 221 symmetrically within the two bends 220, thereby facilitating quick and stable positioning between the two end plates 300 and improving the structural strength and stability of the lower box.

[0071] In some embodiments, the two side panels 200 are respectively a first side panel 201 and a second side panel 202. The first side panel 201 and the second side panel 202 are located on the front and rear sides of the bottom plate 100, respectively. When the lower housing is in the assembled state, the first side panel 201 and the second side panel 202 extend in a third direction.

[0072] Figure 9 yes Figure 8 Enlarged view of the structure at point D.

[0073] See Figure 1 , Figures 2 to 9 In this embodiment, the end plate 300 can be disposed at both ends of the two side plates 200 in the second direction. The end plate 300 can be used to limit the mutual positioning between the two side plates 200, improve the connection strength between the two side plates 200, and thus improve the structural strength and stability of the lower box.

[0074] Furthermore, the end plate 300 can also form an accommodating space with the two side plates 200 and the bottom plate 100 to accommodate and protect display devices with the same length but different widths, thereby protecting the display devices and improving the reliability of the lower cabinet.

[0075] In some embodiments, the end plate 300 may include a first end plate 310 and a second end plate 320. The first end plate 310 and the second end plate 320 are located at the same end in the second direction of the lower housing and are respectively disposed on the two side plates 200 to limit one end of the two side plates 200, thereby improving the connection strength between the two side plates 200 and protecting the two side walls of the display device in the second direction.

[0076] In some embodiments, the two ends of the first side plate 201 in the second direction may be respectively provided with a first end plate 310 and a second end plate 320, and the two ends of the second side plate 202 in the second direction may be respectively provided with a first end plate 310 and a second end plate 320, so that the same end of the two side plates 200 in the second direction is respectively the first end plate 310 and the second end plate 320, thereby enabling the two side plates 200 to be stably and reliably connected and protecting the two side walls of the display device in the second direction.

[0077] In some other embodiments, the two ends of the first side plate 201 in the second direction can be provided with a first end plate 310, and the two ends of the second side plate 202 in the second direction can be provided with a second end plate 320, so that the same end of the two side plates 200 in the second direction is the first end plate 310 and the second end plate 320 respectively, thereby achieving a stable and reliable connection between the two side plates 200 and protecting the two side walls of the display device in the second direction.

[0078] See Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, a second fixing hole 311 may be provided on the first end plate 310. The second fixing hole 311 is used to accommodate and limit the display device. When the lower box is closed to form an accommodating space, the second end plate 320 avoids the second fixing hole 311. When the lower box is closed to form an accommodating space, the second fixing hole 311 can accommodate and limit the foam and / or the display device, thereby improving the reliability and stability of the lower box.

[0079] See Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 In this embodiment, when the lower housing is in the assembled state, the dimensional parameters of the second end plate 320 and the first end plate 310 along the first direction may not be greater than the dimensional parameters of the bottom plate 100 along the first direction. When the bottom plate 100, the two side plates 200, and the multiple end plates 300 enclose and form an accommodating space, the second end plate 320 and the first end plate 310 are both located between the two side plates 200 after bending, thereby ensuring a stable and reliable connection between the first end plate 310 and the second end plate 320 at the same end of the second direction of the two side plates 200. This avoids the second end plate 320 or the first end plate 310 being too long and affecting the enclosure effect, thus ensuring the connection strength and reliability of the lower housing.

[0080] See Figures 1 to 9 In this embodiment, a slot 330 may be provided at the bend between the side plate 200 and the adjacent second end plate 320, and the slot 330 extends along the first direction. The slot 330 is used to engage with the first end plate 310 or other structures thereon to connect and limit the first end plate 310 and the second end plate 320, thereby facilitating the formation of an accommodating space between the first end plate 310, the second end plate 320, the two side plates 200 and the bottom plate 100, and improving the assembly efficiency of the lower box.

[0081] When the socket 330 is located at the bend of the side plate 200 and the adjacent second end plate 320, it also facilitates the fit of the part of the structure extending into the socket 330 with the side plate 200, thereby avoiding interference between the part of the structure extending into the socket 330 and the foam or display device. This allows the lower cabinet to quickly and efficiently accommodate the display device, reducing the occurrence of installation accidents between the lower cabinet and the display device, and improving the reliability, stability and safety of the lower cabinet.

[0082] In some embodiments, the second end plate 320 may be provided with a socket 330, which extends along a first direction so that the socket 330 can be engaged with the first end plate 310 or other structures thereon, so that the first end plate 310, the second end plate 320, the two side plates 200 and the bottom plate 100 can be enclosed to form an accommodating space, thereby improving the assembly efficiency of the lower box.

[0083] See Figures 1 to 9 In this embodiment, the lower housing may further include a tongue 400. The tongue 400 may be disposed on the side of the first end plate 310 away from the first side plate 201. The tongue 400 may be bent relative to the first end plate 310. When the lower housing is in an assembled state, the tongue 400 extends along a first direction. When the lower housing is enclosed to form an accommodating space, the tongue 400 may be positioned between the second end plate 320 and the side plate 200, or the tongue 400 may be positioned on the second end plate 320, so as to realize the connection and positioning between the first end plate 310 and the second end plate 320.

[0084] After the tongue 400 is bent relative to the first end plate 310, its free end can extend into the socket 330 to achieve connection and positioning between the first end plate 310 and the second end plate 320, thereby achieving connection and positioning between the two side plates 200 and enabling rapid assembly of the lower box. Furthermore, the connection and fixation between the tongue 400 and the socket 330 effectively reduces the use of adhesive tape and other bonding components, facilitating the recycling and reuse of the lower box and improving the environmental performance of the box packaging structure.

[0085] When the socket 330 is set on the second end plate 320, after the free end of the tongue 400 is bent and inserted into the socket 330, the free end of the tongue 400 located in the accommodating space continues to be bent to fit the second end wall, thereby avoiding the tongue 400 in the accommodating space from obstructing the accommodating space from accommodating the display device and improving the operating efficiency of the lower cabinet.

[0086] When the socket 330 is located between the side plate 200 and the second end plate 320, after the free end of the tongue 400 is bent and inserted into the socket 330, the free end of the tongue 400 can fit against the adjacent side wall, thereby preventing the tongue 400 extending into the accommodating space from obstructing the accommodating space from accommodating the display device and improving the operating efficiency of the lower cabinet.

[0087] In some embodiments, the tongue 400 and the inner peripheral wall of the socket 330 can be interference-fitted, thereby enabling the tongue 400 to be stably and reliably inserted into the socket 330, improving the connection strength and reliability of the lower housing.

[0088] See Figure 3 , Figure 5 , Figure 7 and Figure 9 In this embodiment, when the lower box is in the assembly state, the tongue 400 may have a second pressure line 410 extending in a third direction, so that the tongue 400 can be bent relative to the second pressure line 410, thereby making it easier for workers to bend the tongue 400 along the second pressure line 410 and improving the assembly efficiency of the lower box.

[0089] In some embodiments, there may be multiple second pressure lines 410, and multiple second pressure lines 410 are spaced apart along the first direction, so that the workers can adaptively select the bending position of the tongue 400 according to the distance between the two side plates 200, thereby facilitating the tongue 400 to bend and extend into the tongue 400, improving the assembly accuracy and efficiency of the lower box, and facilitating the packaging of various display devices with different widths in the lower box.

[0090] In other embodiments, the number of second pressure lines 410 can be the same as the number of first pressure lines 221 in any bend 220, so that the lower housing can be adapted to various display devices with the same length but different widths, thereby improving the versatility of the lower housing and reducing the production cost and warehouse management cost of the lower housing.

[0091] In other embodiments, the distance between any two adjacent first pressure lines 221 within the bending portion 220 is equal to half the distance between any two adjacent second pressure lines 410 within the tongue 400, so that when adjusting the distance between the two side plates 200, the operator can bend the tongue 400 by selecting different positions of the second pressure lines 410, so that the free end of the tongue 400 can be accurately and stably inserted into the socket 330.

[0092] See Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 9 In this embodiment, the second pressure line 410 and the first pressure line 221 can be located on the same side of the bottom plate 100 in the third direction. When the bottom plate 100, the two side plates 200, the multiple end plates 300 and the tongue 400 are enclosed to form an accommodating space, the second pressure line 410 is located on the side wall of the tongue 400 facing the accommodating space. On the one hand, this makes it easier for the tongue 400 to bend towards the accommodating space and be inserted into the socket 330, thereby improving the assembly efficiency of the lower box. On the other hand, it effectively improves the versatility of the lower box, facilitates warehouse storage management, and avoids mixing of various lower boxes.

[0093] See Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 9 In this embodiment, on the third-party side, the two narrow sidewalls of the tongue 400 may be recessed with limiting grooves 420, which are located between any two adjacent second pressure lines 410. When the lower housing is enclosed to form an accommodating space, at least one circumferential sidewall of the socket 330 is engaged and limited in the limiting grooves 420.

[0094] After the workers bend the side plates 200 along the two opposing first pressure lines 221, they then bend the first end plate 310 and the second end plate 320 so that the first end plate 310 and the second end plate 320 at the same end in the second direction are brought closer together. Next, the tongue 400 is bent along the corresponding second pressure line 410 so that the free end of the tongue 400 can extend into the receiving space through the socket 330. Furthermore, the limiting groove 420 of the tongue 400 is used to receive and limit the second end plate 320 around the socket 330, or the limiting groove 420 of the tongue 400 is used to receive and limit the side plates 200 around the socket 330, thereby ensuring the structural strength and stability of the lower housing after it is enclosed to form a receiving space.

[0095] In some embodiments, when the lower housing is in the assembled state, the center line of the tongue 400 is perpendicular to a third direction. On the center line facing the tongue 400, the distance between the two inner sidewalls of the limiting groove 420 can gradually decrease. This allows the limiting groove 420 to accommodate and limit the second end plate 320 or the side plate 200 after the tongue 400 is inserted into the socket 330, thereby improving the connection strength between the first end plate 310 and the second end plate 320 of the tongue 400, preventing the tongue 400 from accidentally coming out of the socket 330, and improving the stability and reliability of the lower housing.

[0096] In other embodiments, the limiting groove 420 may be triangular.

[0097] See Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 9 In this embodiment, in the third direction, the two narrow sidewalls of the tongue 400 may be recessed with notches 430 at the second pressure line 410. On the one hand, this allows the workers to quickly select the second pressure line and improve the assembly efficiency of the lower box; on the other hand, it reduces the length of the tongue 400 in the third direction at the second pressure line 410, thereby facilitating the bending of the tongue 400 at the second pressure line 410 and improving the assembly efficiency of the lower box.

[0098] In some embodiments, in the third-party direction, at least one narrow sidewall of the tongue 400 may be recessed at the second pressure line 410 to facilitate the tongue 400 bending at the second pressure line 410, thereby improving the assembly efficiency of the lower housing.

[0099] See Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 9In this embodiment, the cross-sectional area of ​​the free end of the tongue 400 can be gradually reduced in the direction away from the connected end plate 300, so that after bending the tongue 400, the operator can insert the free end of the tongue 400 into the socket 330, thereby improving the alignment accuracy and assembly efficiency when the tongue 400 is inserted into the socket 330.

[0100] In this embodiment, the bottom plate 100, the two side plates 200 and the end plate 300 can be integrally formed so that the lower box can be formed by cutting and pressing a whole piece of sheet material, thereby facilitating the production of the lower box, reducing the production cost of the lower box, facilitating the assembly and use of the lower box, and improving the structural strength of the lower box.

[0101] In some embodiments, the base plate 100, side plates 200, end plate 300, and tongue 400 can be integrally formed to ensure the structural strength of the lower housing and improve its protective performance.

[0102] In other embodiments, the lower housing can be made of corrugated cardboard, which facilitates the production, bending, and assembly of the lower housing.

[0103] See Figures 1 to 9 This utility model provides a box packaging structure for display devices. When packaging multiple display devices of the same length but different widths, the operator can selectively bend the two side plates 200 symmetrically around the first pressure line 221 within the two bending portions 220 according to the width of the display device, so that the first fixing hole 210 can accommodate a portion of the display device. Then, the first end plate 310 and the second end plate 320 at both ends of the two side plates 200 are bent to accommodate a portion of the display device in the second fixing hole 311. Finally, the operator selectively bends the tongue 400 around a second pressure line 410 according to the width of the display device, and then inserts the free end of the tongue 400 into the insertion port 330 and attaches it to the side plate 200 adjacent to the free end of the tongue 400.

[0104] The bottom plate 100, two side plates 200, end plate 300 and tongue 400 enclose and package the lower part of the display device, so that the lower box can be used to package various display devices with the same length but different widths, which improves the versatility of the lower box and reduces the production cost and warehouse management cost of the lower box.

[0105] In this embodiment, the structure of the upper housing can refer to the structure of the lower housing, which includes an upper bottom plate, two upper side plates and an upper end plate, to enclose and form an accommodating space for accommodating the upper part of the display device.

[0106] In some embodiments, no bending portion is required between the upper base plate and the two upper side plates, and no second pressure line is required on the tongue. The upper housing can accommodate multiple display devices of the same length but different widths, so as to accommodate different display devices respectively.

[0107] In other embodiments, referring to the structure of the lower housing, a bending portion is provided between the upper bottom plate and the two upper side plates, and multiple first pressure lines are provided on the bending portion. Multiple second pressure lines are also provided on the tongue. This allows one upper housing to accommodate multiple display devices of the same length but different widths, thereby reducing the production cost and warehouse storage cost of the upper housing.

[0108] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
