[0035] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0036] In the description and claims of the embodiments of the present disclosure, as well as in the accompanying drawings, the terms "first," "second," and the like are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein.

[0037] In the embodiments of the present disclosure, the terms "upper", "lower", "inside", "middle", "outside", "front", "back" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the embodiments of the present disclosure and their embodiments, and are not intended to limit the indicated devices, elements or components to having a specific direction, or to be constructed and operated in a specific direction. Moreover, in addition to being used to indicate directions or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0038] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two devices, elements, or components.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0041] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0043] In existing related technologies, traditional packaging liners are integrated structures, meaning the entire lower liner is made from a single piece of foam board. This makes assembly and disassembly inconvenient for users. Therefore, existing packaging liners also adopt a split structure, where the lower liner is split into multiple separate structures. Users can separately attach or detach the multiple structures of the lower liner from the flat-panel display device, making operation more convenient.

[0044] However, the split structure of existing packaging liners can cause relative displacement between the multiple lower liners. Therefore, if uneven forces are applied to the flat-panel display during transportation, the existing packaging liners cannot provide deformation protection for the flat-panel display, thus reducing the protective effect of the flat-panel display.

[0045] like Figures 1 to 8 As shown, the present disclosure provides a packaging cushion for a flat panel display device, which is designed to be split for easy assembly and disassembly. Furthermore, during the transportation of the flat panel display device 11, the protective plate 30 ensures the overall deformation resistance of the packaging cushion, thereby ensuring the protection of the flat panel display device 11.

[0046] like Figures 1 to 8 As shown, the embodiment of the present disclosure provides a packaging pad for a flat panel display device 11 , wherein the lower edge of the flat panel display device 11 is configured as a mounting edge. The packaging pad includes: a middle pad 21 , a left pad 22 , a right pad 23 and a guard plate 30 . The middle pad 21 is provided with a middle mounting groove 211 and a first card slot 212, and the middle mounting groove 211 is provided on the side of the middle pad 21 facing the flat panel display device 11; the left pad 22 is provided with a left mounting groove 221 and a second card slot 222, and the left mounting groove 221 is provided on the side of the left pad 22 facing the flat panel display device 11; the right pad 23 is provided with a right mounting groove 231 and a third card slot 232, and the right mounting groove 231 is provided on the side of the right pad 23 facing the flat panel display device 11; the guard plate 30 can be respectively connected to the first card slot 212, the second card slot 222 and the third card slot 232 to limit the middle pad 21, the left pad 22 and the right pad 23; wherein, the middle part of the mounting edge can be inserted into the middle mounting groove 211, the left part of the mounting edge can be inserted into the left mounting groove 221, and the right part of the mounting edge can be inserted into the right mounting groove 231.

[0047] Specifically, the flat panel display device 11 is a television, in particular a flat panel display device. The middle pad 21, the left pad 22 and the right pad 23 are made of a material with a cushioning function, such as foam or sponge, and the thickness of the packaging pad is greater than the thickness of the flat panel display device 11. The middle mounting groove 211 is provided on the upper end surface of the middle pad 21, and the middle mounting groove 211 is provided along the length direction of the middle pad 21; the left mounting groove 221 is provided on the upper end surface of the left pad 22, and the left mounting groove 221 is provided with an opening on the side facing the middle pad 21; the right mounting groove 231 is provided on the upper end surface of the right pad 23, and the right mounting groove 231 is also provided with an opening on the side facing the middle pad 21. The guard plate 30 is made of a rigid material, for example, the guard plate 30 can be made of metal, plastic or glass.

[0048] The user can first insert the left, middle, and right portions of the mounting edge of the flat panel display device 11 into the left mounting slot 221, the middle mounting slot 211, and the right mounting slot 231, respectively. In this way, the packaging cushion can act as a buffer during the transportation of the flat panel display device 11, thereby preventing the flat panel display device 11 from being directly impacted.

[0049] After attaching the flat panel display device 11 to the left, middle, and right pads 22, 21, and 23, the user can snap the protective plate 30 into the first, second, and third slots 212, 222, and 232, respectively. The protective plate 30 prevents relative displacement between the left, middle, and right pads 22, 21, and 23. This prevents uneven force on the flat panel display device 11 during transportation, further enhancing its protection.

[0050] When removing the packaging cushions, the user can first remove the left cushion 22 and the right cushion 23. The center cushion 21 can then provide support, making it easier for the user to install the left and right brackets. Similarly, the user can first remove the center cushion 21. The left cushion 22 and the right cushion 23 can then provide support, making it easier for the user to install the center base. This arrangement makes it easier for the user to install the flat panel display device 11.

[0051] In actual use, the shape and thickness of the central mounting groove 211 of the middle pad 21 correspond to the middle portion of the mounting edge, the shape and thickness of the left mounting groove 221 of the left pad 22 correspond to the left portion of the mounting edge, and the shape and thickness of the right mounting groove 231 of the right pad 23 correspond to the mounting edge. This arrangement increases the fit between the central mounting groove 211, the left mounting groove 221, and the right mounting groove 231 and the mounting edge when the middle pad 21, left pad 22, and right pad 23 are mounted on the mounting edge, further enhancing the protective effect of the packaging pad.

[0052] like Figures 3 to 7 As shown, optionally, the first engaging slot 212, the second engaging slot 222, and the third engaging slot 232 are integrally formed with the central mounting slot 211, the left mounting slot 221, and the right mounting slot 231, respectively. Thus, when the protective plate 30 is engaged with the first engaging slot 212, the second engaging slot 222, and the third engaging slot 232, the protective plate 30 can be attached to the flat panel display device 11. At this point, the protective plate 30 can directly prevent the flat panel display device 11 from deforming, further enhancing the protective effect of the packaging cushion.

[0053] Optionally, the depths of the first card slot 212 , the second card slot 222 and the third card slot 232 are greater than or equal to a preset depth.

[0054] Specifically, the depths of the first card slot 212, the second card slot 222, and the third card slot 232 are greater than or equal to 1 cm. For example, the depths of the first card slot 212, the second card slot 222, and the third card slot 232 can be 1 cm, 2 cm, or 3 cm. This further enhances the protective effect of the packaging cushion on the flat panel display device 11.

[0055] like Figures 3 to 5As shown, in some embodiments, the first card slot 212 is arranged to penetrate along the length direction of the middle pad 21, the second card slot 222 is provided with an opening toward the end of the middle pad 21, and the third card slot 232 is also provided with an opening toward the end of the middle pad 21; wherein, when the middle part of the guard plate 30 is clamped in the first card slot 212, the left part of the clamping edge extends into the second card slot 222 to be clamped in the second card slot 222, and the right part of the clamping edge extends into the third card slot 232 to be clamped in the third card slot 232.

[0056] Specifically, the lower edge of the guard plate 30 is configured as a snap-on edge. A first snap-on slot 212, a second snap-on slot 222, and a third snap-on slot 232 are respectively provided on the upper end surfaces of the middle pad 21, the left pad 22, and the right pad 23. The user can insert the middle portion of the snap-on edge into the first snap-on slot 212 to snap the snap-on edge onto the middle pad 21. At this point, the left portion of the snap-on edge extends toward and inserts into the second snap-on slot 222, while the right portion of the snap-on edge extends toward and inserts into the third snap-on slot 232, so that the snap-on edge simultaneously snaps onto the left pad 22 and the right pad 23, thereby achieving the effect of limiting the position of the left pad 22, the middle pad 21, and the right pad 23.

[0057] In actual use, the size of the portion of the clip edge extending to the second clip slot 222 is greater than or equal to a preset size to ensure a retaining effect on the left pad 22. Similarly, the size of the portion of the clip edge extending to the third clip slot 232 is greater than or equal to a preset size to ensure a retaining effect on the right pad 23.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the distance between the middle pad 21 and the left pad 22 is less than or equal to a preset distance; the distance between the middle pad 21 and the right pad 23 is less than or equal to a preset distance.

[0059] Specifically, the distance between the middle pad 21 and the left pad 22 is less than or equal to 3 cm. For example, the distance between the middle pad 21 and the left pad 22 can be 3 cm, 2 cm, or 1 cm. Similarly, the distance between the middle pad 21 and the right pad 23 is less than or equal to 3 cm. For example, the distance between the middle pad 21 and the right pad 23 can be 3 cm, 2 cm, or 1 cm. This arrangement can further enhance the protective effect of the packaging pad on the flat panel display device 11.

[0060] like Figure 1 and Figure 2 As shown, optionally, when the middle pad 21 , the left pad 22 and the right pad 23 are installed on the flat panel display device 11 , the left pad 22 and the right pad 23 are respectively in contact with both ends of the middle pad 21 .

[0061] like Figure 7 and Figure 8 As shown, in some embodiments, the lower end surfaces of the middle pad 21, the left pad 22 and the right pad 23 are respectively provided with stabilizing grooves 24; wherein, the stabilizing grooves 24 are provided in the middle of the lower end surfaces of the middle pad 21, the left pad 22 and the right pad 23, and the stabilizing grooves 24 are provided along the length direction of the middle pad 21, the left pad 22 and the right pad 23.

[0062] Specifically, the lower end surface of the middle pad 21 is provided with a stabilizing groove 24, extending along the length of the middle pad 21. The front and rear portions of the stabilizing groove 24 form raised structures, which provide support. Similarly, the lower end surfaces of the left and right pads 22 and 23 are also provided with stabilizing grooves 24, extending along their respective lengths. Thus, the raised structures of the left and right pads 22 and 23 also provide support.

[0063] It is understandable that during transportation, the flat panel display device 11 may rock back and forth, which may cause the flat panel display device 11 to squeeze the front and rear edges of the center pad 21, left pad 22, and right pad 23 toward the middle, resulting in the center pad 21, left pad 22, and right pad 23 being thinner at the front and rear edges and having a higher density in the middle. This can cause the center of the center pad 21, left pad 22, and right pad 23 to be harder, while the front and rear edges are softer, which in turn leads to insufficient support on the front and rear sides of the packaging pad, making the flat panel display device 11 prone to tipping over. Therefore, providing stabilizing grooves 24 on the lower end surfaces of the center pad 21, left pad 22, and right pad 23 can improve the stability and support of the packaging pad.

[0064] In some embodiments, the depth of the stabilization groove 24 is greater than or equal to 3 mm and less than or equal to 15 mm.

[0065] Specifically, the depth of the stabilizing groove 24 can be 3 mm, 7 mm, 11 mm, or 15 mm. It is understood that if the depth of the stabilizing groove 24 is less than 3 mm, the stability and support of the packaging cushion cannot be guaranteed; and if the depth of the stabilizing groove 24 is greater than 15 mm, the lower end surfaces of the middle cushion, left cushion, and right cushion of the packaging will be thin.

[0066] like Figure 8 As shown, in some embodiments, the stabilizing groove 24 is provided in a penetrating manner on the lower end surfaces of the middle pad 21 , the left pad 22 and the right pad 23 .

[0067] Specifically, the stabilizing groove 24 is set in the form of passing through the lower end surfaces of the middle pad 21, the left pad 22 and the right pad 23, which can increase the raised structure of the middle pad 21, the left pad 22 and the right pad 23, thereby increasing the stability and support of the packaging pad.

[0068] like Figure 1 As shown, in some embodiments, the upper edge of the front wall or the rear wall of the middle pad 21 is located below the mounting edge.

[0069] Specifically, the upper edge of the front or rear wall of the middle pad 21 is located below the mounting edge to form a clearance opening. Thus, when installing or removing the middle pad 21, the user only needs to move the middle pad 21 forward or backward to allow the flat panel display device 11 to pass through the clearance opening and engage or disengage with the middle pad 21.

[0070] like Figure 1 As shown, in some embodiments, the area of ​​the guard plate 30 is greater than or equal to the first preset area, and less than or equal to the second preset area.

[0071] Specifically, the area of ​​the protective plate 30 is greater than or equal to 1 / 3 of the area of ​​the flat panel display device 11, and less than or equal to the area of ​​the flat panel display device 11. This allows the size of the protective plate 30 to be reduced while still maintaining the effect of the protective plate 30 on the flat panel display device 11. The area of ​​the flat panel display device refers to the area of ​​the front or rear wall of the flat panel display device.

[0072] like Figure 1 and Figure 6 As shown, in some embodiments, a support portion 31 is further provided on the side of the guard plate 30 facing away from the flat panel display device 11 , and the lower end of the support portion 31 can abut against the edge of the first card slot 212 , the second card slot 222 and / or the third card slot 232 .

[0073] Specifically, the side of the guard plate 30 facing away from the flat panel display device 11 is provided with support ribs to form a support portion 31. When the guard plate 30 is engaged with the middle pad 21, left pad 22, and right pad 23, the lower end of the support ribs can abut against the edges of the first engagement slot 212, second engagement slot 222, and / or third engagement slot 232. This support rib increases the contact area between the guard plate 30 and the middle pad 21, left pad 22, and right pad 23, thereby preventing the guard plate 30 from squeezing the middle pad 21, left pad 22, and right pad 23.

[0074] In the above embodiment, the contact area between the supporting ribs and the middle pad 21 , the left pad 22 and the right pad 23 refers to the sum of the contact areas between the supporting ribs and the middle pad 21 , the left pad 22 and the right pad 23 .

[0075] like Figure 1 and Figure 6 As shown, in some embodiments, the guard plate 30 is provided with a plurality of supporting portions 31 , and the plurality of supporting portions 31 are horizontally arranged on a side of the guard plate 30 facing away from the flat panel display device 11 .

[0076] Specifically, a plurality of supporting ribs are evenly arranged on the side of the guard plate 30 facing away from the flat panel display device 11 to further increase the contact area between the guard plate 30 and the middle pad 21 , the left pad 22 and the right pad 23 .

[0077] The above description and the accompanying drawings sufficiently illustrate the embodiments disclosed in this application to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments disclosed in this application are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of this disclosure is limited only by the appended claims.
