Description

Technical Field

[0001] This application relates to the field of packaging technology for home appliances, and more particularly to a packaging structure for a display device. Background Technology

[0002] In the field of display device technology, taking televisions as an example, with the intensification of industry competition and the stimulation of consumption, the TV product market is under pressure in terms of sales volume, while products with high-end attributes such as large size and 120Hz have grown significantly. The trend of large screens has become particularly prominent in the market competition in recent years. Under the trend of large screens, improving the installation experience of large screens has become an industry trend.

[0003] Among them, display devices such as televisions are usually packaged in cartons or other boxes during the logistics process, and protective padding is placed around the display devices to prevent them from being damaged during transportation and movement.

[0004] However, during the logistics process, the packaging boxes and padding of the display devices in the related technologies will inevitably be subjected to external impacts. After being impacted, the packaging boxes and padding will bend and deform, squeezing the screen of the display device, which can easily cause the screen of the display device to crack or break. Utility Model Content

[0005] This application discloses a packaging structure for a display device. By optimizing the padding in related technologies, the protective performance of the packaging box and padding is improved, thereby effectively preventing the screen of the display device from cracking or even breaking during logistics and effectively protecting the display device.

[0006] To achieve the above objectives, this application discloses a packaging structure for a display device, the packaging structure comprising:

[0007] Packaging box, wherein the interior of the packaging box forms a packaging cavity; and,

[0008] A padding structure having a slotted engagement groove for engaging with the edge of the display device, the padding structure being fitted against the cavity wall of the packaging cavity;

[0009] The padding structure has a first front surface and a rear surface disposed opposite to each other along the front-rear direction of the display device. The first front surface is fitted to the front cavity wall of the packaging cavity, and the rear surface is fitted to the rear cavity wall of the packaging cavity.

[0010] The first front surface includes:

[0011] A first sub-front surface, the first sub-front surface being fitted against the front cavity wall of the packaging cavity, and the first sub-front surface being offset from the display device in the front-back direction; and,

[0012] The second sub-front surface is connected to the first sub-front surface and extends toward the center of the display device to cover the edge of the display device. In the arrangement direction of the first sub-front surface and the second sub-front surface, the second sub-front surface is inclined from its connection with the first sub-front surface toward the front cavity wall away from the packaging cavity.

[0013] In the packaging structure of the display device provided in this application embodiment, a sloping structure is designed on the first front surface of the padding structure that adheres to the front cavity wall of the packaging cavity to improve the protective performance of the padding structure. Specifically, the first front surface of the padding structure includes a first sub-front surface and a second sub-front surface connected together. The first sub-front surface is attached to the front cavity wall of the packaging cavity to support the packaging box. At the same time, the second sub-front surface covering the edge of the display device is inclined away from the front cavity wall of the packaging cavity from its connection with the first sub-front surface, so that there is a gap between the second sub-front surface of the padding structure and the front cavity wall of the packaging cavity. This gap provides a certain deformation space for the edge of the front cavity wall of the packaging cavity when subjected to external impact, thereby minimizing the direct transmission of external force to the padding structure. Instead, the padding structure directly transmits the external force to the screen of the display device, effectively preventing the screen of the display device from cracking or even breaking, and effectively protecting the display device.

[0014] In other words, due to the inclined setting of the second sub-front surface, there is a gap between the second sub-front surface of the padding structure and the front cavity wall of the packaging cavity. This increases the gap between the second sub-front surface of the padding structure and the front cavity wall of the packaging cavity. When the edge of the front cavity wall of the packaging cavity deforms under external impact, it can prevent the front cavity wall of the packaging cavity from squeezing the second sub-front surface to a certain extent, causing the padding structure to deform and reducing the degree of deformation at the location of the second sub-front surface. This reduces the degree of squeezing of the screen of the display device at the location of the second sub-front surface, thereby improving the protective performance of the padding structure and effectively preventing the screen of the display device from cracking or even breaking, thus effectively protecting the display device.

[0015] As an optional implementation, in an embodiment of this application, the engaging groove has a groove sidewall surface disposed opposite to the second sub-front surface, and the groove sidewall surface is inclined toward the front cavity wall of the packaging cavity in the groove opening direction of the engaging groove.

[0016] This design allows for a gap between the side wall of the locking groove and the display screen of the display device. This gap provides a certain deformation space for the side wall of the groove when the front wall edge of the packaging cavity is impacted by external forces. As a result, when the front wall edge of the packaging cavity is subjected to external forces, the deformation of the padding structure can be minimized to prevent it from directly pressing on the display screen of the display device. This can more effectively prevent the display screen from cracking or breaking and can further better protect the display device.

[0017] As an optional implementation, in an embodiment of this application, the first front surface includes a connecting side that extends along the front-rear direction of the display device and connects between the first sub-front surface and the second sub-front surface.

[0018] This increases the gap between the front wall of the packaging cavity and the front surface of the second sub-sub ...

[0019] As an optional implementation, in an embodiment of this application, an accommodating space is formed between the second sub-front surface and the connecting side surface, and the packaging structure further includes a first front pad, which is disposed in the accommodating space and is used to cover the front side of the display device.

[0020] In the above design, on the one hand, the first front pad can be used to separately protect the display screen on the front side of the display device, further protecting the display screen and providing better protection. On the other hand, the accommodating space can be used to roughly define the installation position of the first front pad, providing initial positioning for the installation of the first front pad and facilitating its installation; at the same time, the accommodating space can also limit the movement of the first front pad to a certain extent, preventing it from moving arbitrarily and ensuring that the first front pad can be set to correspond to the display screen of the display device, thus protecting the display screen.

[0021] As an optional implementation, in an embodiment of this application, the packaging structure further includes a first front liner, which is attached between the first sub-front surface and the front cavity wall of the packaging cavity, and the first front liner is used to cover the front side of the display device.

[0022] This configuration allows for separate protection of the display screen on the front side of the display device using the first front pad, further protecting the display screen on the front side of the display device and providing better protection for it.

[0023] As an optional implementation, in an embodiment of this application, the packaging structure further includes a second front liner, which is used to adhere to the front side of the display device, and the edge of the second front liner and the edge of the display device are clamped in the engagement groove.

[0024] By adding a second front pad on top of the first front pad, the display screen of the device can be further protected, providing dual protection and better safeguarding the display screen.

[0025] In addition, since the second front pad is attached to the front side of the display device, that is, the second front pad is attached to the display screen of the display device, the second front pad is in direct contact with the display screen. By enabling the second front pad to be locked in the locking groove of the pad structure along with the display device, the second front pad is limited to a certain extent, which can prevent the second front pad from sliding. This can prevent scratches on the display screen on the front side of the display device and more effectively protect the display screen on the front side of the display device.

[0026] As an optional implementation, in an embodiment of this application, the packaging structure further includes a second front liner, which is used to adhere to the front side of the display device, and the edge of the second front liner and the edge of the display device are clamped in the engagement groove.

[0027] This configuration allows for separate protection of the display screen on the front side of the display device using a second front pad, further protecting the display screen on the front side of the display device and providing better protection for it.

[0028] In addition, since the second front pad is attached to the front side of the display device, that is, the second front pad is attached to the display screen of the display device, the second front pad is in direct contact with the display screen. By enabling the second front pad to be locked in the locking groove of the pad structure along with the display device, the second front pad is limited to a certain extent, which can prevent the second front pad from sliding. This can prevent scratches on the display screen on the front side of the display device and more effectively protect the display screen on the front side of the display device.

[0029] As an optional implementation, in an embodiment of this application, the padding structure has a second front surface, which is disposed facing the front cavity wall of the packaging cavity, and the second front surface is provided with a first rib. The first rib divides the second front surface into a third sub-front surface and a fourth sub-front surface. In the arrangement direction of the third sub-front surface and the fourth sub-front surface, the fourth sub-front surface is closer to the center of the display device than the third sub-front surface. The fourth sub-front surface is provided with a plurality of second ribs, which are spaced apart along the extension direction of the first rib, and each second rib extends along the arrangement direction of the third sub-front surface and the fourth sub-front surface.

[0030] The surface of the first rib facing the front wall of the packaging cavity forms the first front side surface, and the surface of the second rib facing the front wall of the packaging cavity forms the second front side surface.

[0031] In the above structural design, the first rib can be used to better support the front cavity wall of the packaging box; and the gap formed between two adjacent second ribs can be used to further increase the deformation relief space of the front cavity wall of the packaging box, which can more effectively prevent the display screen of the display device from cracking or breaking, and provide better protection for the display screen.

[0032] As an optional implementation, in the embodiments of this application, the packaging structure does not include a front liner.

[0033] By tilting the second sub-front surface of the padding structure to increase the gap between the second sub-front surface and the front cavity wall of the packaging cavity, this application improves the protective performance of the padding structure, preventing the display screen of the display device from being squeezed and broken during transportation. Therefore, this application eliminates the need for a front padding on the front side of the padding structure, saving on the cost of the front padding and eliminating the need to reserve installation space for the front padding inside the packaging box. This reduces the thickness of the packaging structure in the front-rear direction of the display device, thus facilitating a thinner and lighter packaging design.

[0034] As an optional implementation, in an embodiment of this application, the packaging structure includes:

[0035] An upper pad, the upper pad being used to engage with the upper edge of the display device, and the upper pad being used to adhere to the upper end of the packaging cavity;

[0036] The lower liner is used to engage with the lower edge of the display device and to adhere to the lower end of the packaging cavity;

[0037] A left liner, the left liner being used to engage with the left edge of the display device and to adhere to the left side of the packaging cavity; and

[0038] A right liner, the right liner being used to engage with the right edge of the display device, and the right liner being used to adhere to the right side of the packaging cavity;

[0039] Wherein, at least one of the upper pad, the lower pad, the left pad, and the right pad is the pad structure.

[0040] In this way, the display device can be protected from all sides, providing better and more comprehensive protection. This will greatly reduce the return rate of the display device during transportation and lower the maintenance cost. Attached Figure Description

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0058] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] The terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first front liner may be referred to as a second front liner, and similarly, a second front liner may be referred to as a first front liner. Both the first and second front liners are front liners, but they are not the same front liner.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0062] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0063] In addition, the term "and / or" as used in this specification includes any and all combinations of the related listed items. For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0064] Currently, both home and commercial display devices (such as televisions) are packaged using packaging structures (which typically include boxes and padding). During transportation, the protective effect of the packaging structure on the display device is related to the user's overall experience of purchasing the display device. Whether the display device can have a good packaging form and a good packaging effect is a great challenge to improve product quality and customer satisfaction.

[0065] However, because the screen on the front of the display device is relatively fragile, and the display device will inevitably be subject to collisions and drops during transportation, the packaging box and padding will be subjected to external impacts, causing the packaging box and padding to bend and deform, squeezing the screen of the display device, which can easily cause the screen of the display device to crack or break. This results in a relatively high damage rate of the screen of the display device. For example, the damage rate of the screen of the display device can reach about 3.44%, which greatly increases the defect rate of the display device during transportation and causes a high return rate.

[0066] Especially when the space in the packaging box along its thickness (i.e., the thickness of the display device) is limited, the padding becomes thinner, making it more prone to bending and deformation under external impact. This can easily crush the display screen, leading to screen damage during transportation, higher return rates, and persistently high sales and repair costs. Therefore, developing new packaging structures for display devices to solve these problems is of significant practical importance.

[0067] In view of this, embodiments of this application provide a packaging structure that can effectively prevent the screen of a display device from cracking or even breaking during logistics within a limited packaging cavity.

[0068] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] Figure 1 This is a schematic diagram of a packaging structure for wrapping around a display device in one embodiment of this application. Figure 2 This is an exemplary structural diagram of a padding structure in this application that surrounds a display device. Figure 3 This is an exemplary cross-sectional schematic diagram of a packaging structure for packaging around a display device, as described in this application.

[0070] Please see Figures 1 to 3 This application provides a packaging structure for a display device. The packaging structure 200 is disposed on the outer periphery of the display device 100 to protect the display device 100 during transportation and to prevent the display device 100 from being damaged during transportation.

[0071] For ease of description and understanding, this application uses the state of the display device 100 in upright use as a reference. The direction facing the user is front, the direction away from the user is back, the thickness direction of the display device 100 is front-back, the height direction of the display device 100 is up-down, and the width direction of the display device 100 is left-right. The direction towards the center of the display device 100 is inward, and the direction away from the center of the display device 100 is outward.

[0072] In this application, the display device 100 may include, but is not limited to, electronic products such as televisions, computer monitors, and digital photo frames. The structure of the display device 100 will be specifically described below using a television as an example.

[0073] In some embodiments, the display device 100 may be a plate-like structure, and the display device 100 may include a housing with a front opening and a display screen disposed on the front side of the housing. The display screen is fixed to the front side of the housing and serves as the display surface of the device for displaying image information.

[0074] In this application, the display screen on the front side of the display device 100 may include, but is not limited to, a liquid crystal display (LCD) or an organic light-emitting diode display (OLED), or other display screens that can be used to realize the image display function. The implementation method of this application does not specifically limit this.

[0075] In this application, the housing contains accessories such as a motherboard, a power board, a sound component, and electronic components.

[0076] The motherboard is located inside the casing and on the back of the display screen. It is mainly used to perform calculations on the control system of the display body and output relevant operation commands accordingly.

[0077] The power supply board is integrated on the motherboard and is mainly used to provide the motherboard with drive voltage or stable operating voltage and to keep the output current of the circuits on the motherboard stable when they are working.

[0078] The sound components are located on the back, left and right sides, or front of the motherboard, and are mainly used to produce corresponding sounds in conjunction with the interface displayed on the screen.

[0079] Electronic components are connected to the back of the motherboard. The motherboard has a large number of electronic components, which mainly transmit the operation commands output by the motherboard to the corresponding operation terminals.

[0080] Please see Figures 1 to 3 The packaging structure 200 provided in this application embodiment may include a packaging box 21 and a padding structure 22 disposed inside the packaging box 21.

[0081] Specifically, the internal structure of the packaging box 21 forms a packaging cavity 211, and the padding structure 22 is disposed in the packaging cavity 211 inside the packaging box 21 to keep the display device 100 inside the packaging box 21 to cushion impacts, protect the display device 100 during transportation, and protect the display device 100 when it is removed from the packaging box 21.

[0082] Optionally, the packaging box 21 is generally a cardboard box, which is usually slightly larger than the external dimensions of the display device 100, so as to fix and place the display device 100 and the like inside, while taking up less space.

[0083] Furthermore, the packaging box 21 can typically be made of single or multiple layers of corrugated paper spliced ​​and glued together.

[0084] Alternatively, the padding structure 22 may be made of foam or other cushioning materials.

[0085] As an example, the padding structure 22 can be made of expandable polystyrene (EPS), also known as expanded polystyrene. Because expandable polystyrene has advantages such as high density and strength, it can improve the rigidity of the padding structure 22, reduce the deformation of the padding structure 22, and prevent the padding structure 22 from being too easily deformed.

[0086] Another example is that the padding structure 22 can be made of expandable polyethylene foam (EPE), also known as pearl cotton. Because it consists of completely independent air bubbles, it is lightweight, flexible, and bendable, absorbing and dispersing impact forces to provide a cushioning effect. This overcomes the shortcomings of ordinary expanded foam, such as fragility, deformation, and poor resilience. Expandable polyethylene has properties such as heat insulation, water resistance, moisture resistance, sound insulation, friction resistance, aging resistance, and corrosion resistance. Furthermore, it has strong aging resistance and good processability. Pink expandable polyethylene raw materials with added antistatic agents also have significant antistatic properties. When laminated with PO (polyolefin) films, aluminum foil, woven fabrics, etc., it can also increase tear strength and UV protection.

[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the padding structure 22 has a slotted engagement groove 221 for engaging with the edge of the display device 100, and the padding structure 22 is fitted to the cavity wall of the packaging cavity 211 to fix the display device 100 in the packaging cavity 211 of the packaging box 21.

[0088] In some embodiments, the padding structure 22 has a first front surface 222 and a rear surface 223 disposed opposite to each other in the front-rear direction of the display device 100. The first front surface 222 is fitted to the front cavity wall of the packaging cavity 211, and the rear surface 223 is fitted to the rear cavity wall of the packaging cavity 211. The first front surface 222 includes a first sub-front surface 222a and a second sub-front surface 222b.

[0089] The first sub-front surface 222a is fitted against the front cavity wall of the packaging cavity 211, and the first sub-front surface 222a is offset from the display device 100 in the front-rear direction, that is, the first sub-front surface 222a does not coincide with the display device 100 in the front-rear direction. In other words, the projection of the first sub-front surface 222a on the rear cavity wall of the packaging cavity 211 does not coincide with the projection of the display device 100 on the rear cavity wall of the packaging cavity 211. Thus, even if the packaging box 21 is impacted by an external force, causing the first sub-front surface 222a to deform, it will not squeeze the display device 100 and cause the display screen to crack or break.

[0090] The second sub-front surface 222b is connected to the first sub-front surface 222a and extends toward the center of the display device 100 to cover the edge of the display device 100. In the arrangement direction of the first sub-front surface 222a and the second sub-front surface 222b, the second sub-front surface 222b is inclined from its connection with the first sub-front surface 222a toward the front cavity wall away from the packaging cavity 211.

[0091] The protective performance of the padding structure 22 is improved by designing a ramp structure on the first front side surface 222 that fits against the front cavity wall of the packaging cavity 211. Specifically, the first front surface 222 of the padding structure 22 includes a first sub-front surface 222a and a second sub-front surface 222b connected together. The first sub-front surface 222a is fitted to the front cavity wall of the packaging cavity 211 to support the packaging box 21. At the same time, the second sub-front surface 222b covering the edge of the display device 100 is inclined away from the connection point with the first sub-front surface 222a towards the front cavity wall of the packaging cavity 211, so that there is a gap between the second sub-front surface 222b of the padding structure 22 and the front cavity wall of the packaging cavity 211. This gap provides a certain deformation space for the edge of the front cavity wall of the packaging cavity 211 when subjected to external force impact. This can minimize the direct transmission of external force to the edge of the front cavity wall of the packaging cavity 211 to the padding structure 22, which instead directly transmits the external force to the display screen of the display device 100. This can effectively prevent the display screen of the display device 100 from cracking or even breaking, and effectively protect the display device 100.

[0092] That is, because the second sub-front surface 222b is inclined, there is a gap between the second sub-front surface 222b of the padding structure 22 and the front cavity wall of the packaging cavity 211. This increases the gap between the second sub-front surface 222b of the padding structure 22 and the front cavity wall of the packaging cavity 211. When the edge of the front cavity wall of the packaging cavity 211 deforms under external impact, it can prevent the front cavity wall of the packaging cavity 211 from squeezing the second sub-front surface 222b to a certain extent, causing the padding structure 22 to deform and reducing the degree of deformation at the location of the second sub-front surface 222b. This reduces the degree of squeezing of the display screen of the display device 100 at the location of the second sub-front surface 222b, thereby improving the protective performance of the padding structure 22. It can effectively prevent the display screen of the display device 100 from cracking or even breaking, effectively protecting the display device 100 and helping to reduce the return rate of the display device 100 during transportation and reduce the maintenance cost of the display device 100.

[0093] Understandably, the transportation process of the display device 100 includes at least one of the following processes:

[0094] The first is the process of moving the display device 100 onto a transport vehicle (such as a truck, ship, or airplane). In this process, it is inevitable that there will be drops or collisions, which will cause the front wall of the packaging cavity 211 to be impacted by external forces.

[0095] Secondly, during the process of transporting the display device 100 from one location to another by a transport vehicle, collisions and bumps are inevitable, which will cause the front wall of the packaging cavity 211 to be impacted by external forces.

[0096] Thirdly, during the handling process of moving the display device 100 from the transport vehicle, there will inevitably be situations of falling and collision, which will cause the front wall of the packaging cavity 211 to be impacted by external forces.

[0097] In some embodiments, such as Figure 3 As shown, the engaging groove 221 has a groove side wall 221a disposed opposite to the second front side surface 222b. In the groove opening direction of the engaging groove 221, the groove side wall 221a is inclined toward the front cavity wall of the packaging cavity 211.

[0098] This configuration allows for a gap between the slot sidewall 221a of the locking groove 221 and the display screen of the display device 100. This gap provides a certain deformation space for the slot sidewall 221a when the front cavity wall edge of the packaging cavity 211 is impacted by external force. As a result, when the front cavity wall edge of the packaging cavity 211 is subjected to external force, the padding structure 22 can be prevented from directly pressing the display screen of the display device 100 when it deforms. This can more effectively prevent the display screen of the display device 100 from cracking or breaking, and further better protect the display device 100.

[0099] When the edge of the front cavity wall of the packaging cavity 211 deforms under external impact, or even when the padding structure 22 deforms, the gap between the groove side wall 221a of the locking groove 221 and the display screen of the display device 100 can, to a certain extent, prevent the front cavity wall of the packaging cavity 211 from pressing the second sub-front surface 222b, causing the padding structure 22 to deform and reducing the degree of deformation at the location of the second sub-front surface 222b. This reduces the pressure of the second sub-front surface 222b on the display screen of the display device 100, thereby improving the protective performance of the padding structure 22. This can effectively prevent the display screen of the display device 100 from cracking or even breaking, reducing the damage rate of the display screen during transportation. For example, the damage rate of the display screen during transportation can be reduced to about 0.01%, effectively protecting the display device 100 and helping to reduce the return rate of the display device 100 during transportation, thus reducing the maintenance cost of the display device 100.

[0100] In some embodiments, such as Figure 2 and Figure 3 As shown, the packaging structure 200 may include an upper pad 22a, a lower pad 22b, a left pad 22c, and a right pad 22d. The upper pad 22a is used to engage with the upper edge of the display device 100 and is also attached to the upper end of the packaging cavity 211; the lower pad 22b is used to engage with the lower edge of the display device 100 and is also attached to the lower end of the packaging cavity 211; the left pad 22c is used to engage with the left edge of the display device 100 and is also attached to the left side of the packaging cavity 211; and the right pad 22d is used to engage with the right edge of the display device 100 and is also attached to the right side of the packaging cavity 211. In this way, the display device 100 can be protected from all sides, providing better and more comprehensive protection for the display device 100. This will greatly reduce the return rate of the display device 100 during transportation and lower the maintenance cost of the display device 100.

[0101] At least one of the upper pad 22a, lower pad 22b, left pad 22c, and right pad 22d is the pad structure 22 described above. That is, there can be one and only one pad that is the pad structure 22 described above, for example, the upper pad 22a, lower pad 22b, left pad 22c, or right pad 22d is the pad structure 22 described above; or there can be one and only two pads that are the pad structure 22 described above, for example, the upper pad 22a and lower pad 22b are the pad structure 22 described above, or the upper pad 22a and left pad 22c are the pad structure 22 described above, or the upper pad 22a and right pad 22d are the pad structure 22 described above, or the lower pad 22b and left pad 22c are the pad structure 22 described above, or the lower pad 22b and right pad 22d are the pad structure described above. Structure 22, for example, left pad 22c and right pad 22d are the pad structure 22 described above; or, there may be one and only three pads that are the pad structure 22 described above, for example, upper pad 22a, lower pad 22b and left pad 22c are the pad structure 22 described above, for example, upper pad 22a, lower pad 22b and right pad 22d are the pad structure 22 described above, for example, lower pad 22b, upper pad 22a and right pad 22d are the pad structure 22 described above; or, all four pads are the pad structure 22 described above, that is, upper pad 22a, lower pad 22b, left pad 22c and right pad 22d are all the pad structure 22 described above.

[0102] When the upper liner 22a is the liner structure 22 described above, the groove opening of the engaging groove 221 of the upper liner 22a is set downward, the second sub-front surface 222b is located below the first sub-front surface 222a, the second sub-front surface 222b is set downward and backward, and the groove side wall 221a is set downward and forward.

[0103] When the lower liner 22b is the aforementioned liner structure 22, the groove opening of the engagement groove 221 of the lower liner 22b is set upwards, the second sub-front surface 222b is located above the first sub-front surface 222a, the second sub-front surface 222b is set upwards and backwards, and the groove side wall 221a is set upwards and forwards.

[0104] When the left pad 22c is the pad structure 22 described above, the slot opening of the engagement groove 221 of the left pad 22c is set to the right, the second sub-front surface 222b is located to the right of the first sub-front surface 222a, the second sub-front surface 222b is set to the right and backward, and the groove side wall 221a is set to the right and forward.

[0105] When the right pad 22d is the pad structure 22 described above, the slot opening of the engaging groove 221 of the right pad 22d is set to the left, the second sub-front surface 222b is located to the left of the first sub-front surface 222a, the second sub-front surface 222b is set to the left and backward, and the groove side wall 221a is set to the left and forward.

[0106] As can be seen from the foregoing, by tilting the second sub-front surface 222b of the padding structure 22 to increase the gap between the second sub-front surface 222b and the front cavity wall of the packaging cavity 211, the protective performance of the padding structure 22 can be improved, preventing the display screen of the display device 100 from being squeezed during transportation, thus preventing the display screen from cracking or breaking.

[0107] Therefore, in some embodiments, such as Figure 3 and Figure 4 As shown, a front pad may not be provided on the front side of the padding structure 22, that is, the packaging structure 200 in this application does not include a front pad. This can save the cost of the front pad, and there is no need to reserve installation space for the front pad inside the packaging box 21, thereby reducing the thickness of the packaging structure 200 in the front-back direction of the display device 100, which is conducive to realizing a thinner and lighter design of the packaging structure 200.

[0108] In other embodiments, such as Figure 5 and Figure 6 As shown, the packaging structure 200 may include a first front pad 23, which is attached between the first front surface 222a and the front cavity wall of the packaging cavity 211, and the first front pad 23 is used to cover the front side of the display device 100. Thus, the first front pad 23 can be used to separately protect the display screen on the front side of the display device 100, further protecting the display screen on the front side of the display device 100 and providing better protection.

[0109] As an example, the first front pad 23 can be a honeycomb panel, so that when subjected to external impact, the pores of the honeycomb panel can effectively absorb and disperse energy, which can greatly buffer the impact of drops, collisions, bumps and other common occurrences during transportation on the display screen, and prevent the display screen from breaking or developing internal damage such as dark spots or bright lines.

[0110] Another example is that the first front pad 23 can be made of a flexible material, such as expandable polyethylene foam (EPE). The hardness of the material of the first front pad 23 can be less than that of the pad structure 22. Therefore, even if the first front pad 23 comes into contact with the display screen on the front side of the display device 100, the contact between the first front pad 23 and the display screen can be a soft contact, thereby reducing the damage caused by the first front pad 23 to the display screen on the front side of the display device 100.

[0111] In some embodiments, such as Figure 6 As shown, the first front surface 222 may include a connecting side 222c, which extends along the front-rear direction of the display device 100 and connects between the first sub-front surface 222a and the second sub-front surface 222b. This increases the gap between the front cavity wall of the packaging cavity 211 and the second sub-front surface 222b, providing greater deformation space for the front cavity wall of the packaging cavity 211. This allows the front cavity wall of the packaging cavity 211 to deform to a greater extent when subjected to a large external impact, and also minimizes the risk of deformation at the location of the second sub-front surface 222b, which could compress the display screen and cause damage. This better protects the display screen.

[0112] In some embodiments, such as Figure 6 As shown, the first front liner 23 is disposed in the receiving space 222d formed between the second sub-front surface 222b and the connecting side surface 222c. That is, a receiving space 222d is formed between the second sub-front surface 222b and the connecting side surface 222c, and the first front liner 23 is disposed in this receiving space 222d.

[0113] This allows the accommodating space 222d to roughly define the installation position of the first front pad 23, providing initial positioning for its installation and facilitating its installation. Simultaneously, the accommodating space 222d can also limit the movement of the first front pad 23, preventing it from moving freely and ensuring it aligns with the display screen of the display device 100, thus protecting the display screen.

[0114] In some embodiments, such as Figure 7As shown, the packaging structure 200 may include a second front pad 24, which is used to adhere to the front side of the display device 100, and the edge of the second front pad 24 and the edge of the display device 100 are clamped in the engagement groove 221.

[0115] In this way, the display screen on the front side of the display device 100 can be individually protected by the second front pad 24, which can further protect the display screen on the front side of the display device 100 and better protect the display screen on the front side of the display device 100.

[0116] In addition, since the second front pad 24 is attached to the front side of the display device 100, that is, the second front pad 24 is attached to the display screen of the display device 100, the second front pad 24 is in direct contact with the display screen. By enabling the second front pad 24 to be engaged together with the display device 100 in the engagement groove 221 of the pad structure 22, the second front pad 24 is limited to a certain extent, which can prevent the second front pad 24 from sliding, thereby preventing scratches on the display screen on the front side of the display device 100 and more effectively protecting the display screen on the front side of the display device 100.

[0117] In some embodiments, such as Figure 8 As shown, the packaging structure 200 may include a first front pad 23 and a second front pad 24, thereby providing dual protection for the display screen of the display device 100 and better protecting the display screen.

[0118] As an example, the second front pad 24 can be a honeycomb panel, so that when subjected to external impact, the pores of the honeycomb panel can effectively absorb and disperse energy, which can greatly buffer the impact of drops, collisions, bumps and other common occurrences during transportation on the display screen, and prevent the display screen from breaking or developing internal damage such as dark spots or bright lines.

[0119] Another example is that the second front pad 24 can be made of a flexible material, such as expandable polyethylene foam (EPE). The hardness of the material of the second front pad 24 can be less than that of the pad structure 22, so that the contact between the second front pad 24 and the display screen is a soft contact. In this way, even if the second front pad 24 slides relative to the display screen, the frictional damage caused by the second front pad 24 to the display screen on the front side of the display device 100 can be reduced.

[0120] In some embodiments, such as Figure 8 and Figure 9As shown, the padding structure 22 has a second front surface 224, which is disposed toward the front cavity wall of the packaging cavity 211, and the second front surface 224 is provided with a first rib 225, which divides the second front surface 224 into a third sub-front surface 224a and a fourth sub-front surface 224b. In the arrangement direction of the third sub-front surface 224a and the fourth sub-front surface 224b, the fourth sub-front surface 224b is closer to the center of the display device 100 than the third sub-front surface 224a. The fourth sub-front surface 224b is provided with a plurality of second ribs 226, which are spaced apart along the extension direction of the first rib 225, and each second rib 226 extends along the arrangement direction of the third sub-front surface 224a and the fourth sub-front surface 224b.

[0121] The surface of the first rib 225 facing the front wall of the packaging cavity 211 forms a first sub-front surface 222a, and the surface of the second rib 226 facing the front wall of the packaging cavity 211 forms a second sub-front surface 222b.

[0122] In the above structural design, the first rib 225 can be used to better support the front cavity wall of the packaging box 21; and the gap formed between two adjacent second ribs 226 can be used to further increase the deformation relief space of the front cavity wall of the packaging box 21, which can more effectively avoid cracking or breaking of the display screen of the display device 100 and provide better protection for the display screen.

[0123] In addition, since the third sub-front surface 224a and the front cavity wall of the packaging cavity 211 are spaced apart, when the front cavity wall of the packaging cavity 211 is subjected to an external force impact at the position corresponding to the third sub-front surface 224a, the front cavity wall of the packaging cavity 211 can, to a certain extent, avoid the pressure of the third sub-front surface 224a on the position of the third sub-front surface 224a. This can reduce the probability of damage to the padding structure 22, so that the padding structure 22 can protect the display device 100.

[0124] In some embodiments, the third sub-front surface 224a is provided with a plurality of third ribs 227, which are spaced apart along the extending direction of the first rib 225, and each third rib 227 extends along the arrangement direction of the third sub-front surface 224a and the fourth sub-front surface 224b. This allows for the use of the gap between two adjacent third ribs 227 to provide deformation relief space for the front cavity wall of the packaging box 21, reducing the pressure of the edge of the front cavity wall of the packaging cavity 211 on the padding structure 22; and the multiple third ribs 227, together with the first rib 225, can jointly support the front cavity wall of the packaging cavity 211, providing a more stable support for the front cavity wall of the packaging cavity 211.

[0125] Please see Figure 10This diagram illustrates the stress distribution of a display screen when it is surrounded by a packaging structure based on related technologies. The stress distribution contour plot shows the distribution of the maximum Mises stress (S_max, Mises) on the negative normal surface of the display screen (fraction = -1.0). The data has been averaged by 75% (Avg: 75%), and the stress unit is megapascals (MPa), where e+02 represents 10 to the power of 2 (i.e., 100). Figure 10 It is known that the maximum stress value is about 150.0 MPa, which indicates that when the packaging structure in the relevant technology is used to wrap the display device, the display screen is subjected to a relatively large force, making the display screen more prone to breakage.

[0126] Please see Figure 11 This diagram illustrates the stress distribution of the display screen in this application. The stress distribution contour plot shows the distribution of the maximum Mises stress (S_max, Mises) on the negative normal surface of the display screen (fraction = -1.0). The data has been averaged by 75% (Avg: 75%), and the stress unit is megapascals (MPa), where e+02 represents 10 to the power of 2 (i.e., 100). Figure 11 It is known that the maximum stress value is about 100.0 MPa, which is much smaller than 150 MPa. This indicates that when the packaging structure in this application is used to wrap the display device, the force on the display screen is relatively small, which can reduce the risk of the display screen breaking.
