[0039] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0043] At present, the packaging of many motherboards on the market is an integrally formed structure. Although the structure is compact, it has certain limitations in terms of space division and load-bearing and compression resistance, and mainly protects the upper part of the motherboard, that is, the front of the motherboard, and there are fewer protective structures for the back of the motherboard.

[0044] With the replacement of motherboards, many interfaces are also installed on the back of some motherboards, and conventional linings cannot protect the interfaces on the back of the motherboard during transportation.

[0045] Based on this, the embodiments of the present application provide a three-piece assembled lining and a packaging structure for protecting the back of electronic products during transportation.

[0046] The following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0047] Figure 1 It is a schematic structural diagram of a three-piece assembled lining provided by an embodiment of the present application.

[0048] Referring to Figure 1 , a three-piece assembled lining provided by an embodiment of the present application for electronic products, the three-piece assembled lining includes a first lining structure 10, a second lining structure 20 and a third lining structure 30;

[0049] The second lining structure 20 and the third lining structure 30 are installed on opposite sides of the first lining structure 10 along a first direction, and the first lining structure 10, the second lining structure 20 and the third lining structure 30 enclose a first accommodation space 40;

[0050] The surface of the first lining structure 10 facing away from the first accommodation space 40 and the second lining structure 20 enclose a first buffer cavity 41, and the surface of the first lining structure 10 facing away from the first accommodation space 40 and the third lining structure 30 enclose a second buffer cavity 42.

[0051] From the composition structure of the above three-piece assembled lining, referring to Figure 1, In specific implementation, the electronic product can be placed in the first accommodation space 40 enclosed by the first inner lining structure 10, the second inner lining structure 20, and the third inner lining structure 30, and the electronic product carried is limited and protected through the first accommodation space 40. Below the first accommodation space 40, the second inner lining structure 20 and the third inner lining structure 30 respectively form a first buffer cavity 41 and a second buffer cavity 42 with the first inner lining structure 10. Since the second inner lining structure 20 and the third inner lining structure 30 are respectively installed on the opposite sides of the first inner lining structure 10 along the first direction, the enclosed first buffer cavity 41 and second buffer cavity 42 can support from the opposite sides below the first accommodation space 40, lift the first accommodation space 40 carrying the electronic product, so that the lower part of the first accommodation space 40 is suspended, and thus the impact or pressure received will not directly act on the structure on the back of the electronic product, but will first be dispersed and act on the first buffer cavity 41 and the second buffer cavity 42, and the impact transmitted to the electronic product will be mitigated through the first buffer cavity 41 and the second buffer cavity 42. Based on this, the three-piece assembled inner lining provided by the embodiments of the present application improves the buffer protection and compressive resistance effect on the back of the electronic product, can reduce the collision damage to the back of the electronic product during transportation, and protects the structure and performance of the electronic product. At the same time, the three-piece assembled inner lining provided by the embodiments of the present application is a split inner lining structure assembled by the first inner lining structure 10, the second inner lining structure 20, and the third inner lining structure 30. Compared with the integrally formed inner lining structure, the inner lining structure formed by the three-piece assembly method uses less materials, wastes less raw materials, has a low structural cost, and can solve the limitations of the integrally formed structure in terms of space division and load-bearing and compressive resistance.

[0052] Exemplarily, in the embodiments of the present application, the electronic product carried and protected by the three-piece assembled inner lining can be a main board with a suitable size and any configuration.

[0053] Figure 2 It is a schematic diagram of the unfolded structure of the first inner lining structure provided by the embodiments of the present application. Figure 3 It is a schematic diagram of the unfolded structure of the second inner lining structure provided by the embodiments of the present application. Figure 4 It is a schematic diagram of the unfolded structure of the third inner lining structure provided by the embodiments of the present application.

[0054] As a possible implementation manner, in combination with Figures 1 to 4 , the first inner lining structure 10 includes a first side portion 11, a bottom plate 12, and a second side portion 13 that are sequentially connected. The first side portion 11 and the second side portion 13 are oppositely arranged along the second direction, and the second direction is different from the first direction;

[0055] The second inner lining structure 20 includes a third side portion 21, a first connecting portion 22, a second connecting portion 23, a third connecting portion 24, and a fourth side portion 25 that are connected in sequence. The third side portion 21, the second connecting portion 23, and the fourth side portion 25 are arranged along the first direction, and the third side portion 21 is located between the second connecting portion 23 and the fourth side portion 25. The first connecting portion 22 and the third connecting portion 24 are disposed opposite to each other along the thickness direction of the three-piece assembled inner lining; the thickness direction is different from both the second direction and the first direction;

[0056] The third inner lining structure 30 includes a fifth side portion 31, a fourth connecting portion 32, a fifth connecting portion 33, a sixth connecting portion 34, and a sixth side portion 35 that are connected in sequence. The fifth side portion 31, the fifth connecting portion 33, and the sixth side portion 35 are arranged along the first direction, and the fifth side portion 31 is located between the fifth connecting portion 33 and the sixth side portion 35. The fourth connecting portion 32 and the sixth connecting portion 34 are disposed opposite to each other along the thickness direction of the three-piece assembled inner lining;

[0057] The first side portion 11, the second side portion 13, the third side portion 21, and the fifth side portion 31 and the bottom plate 12 enclose a first accommodation space 40.

[0058] Based on this, in combination with Figures 1 to 4 , the first inner lining structure 10, the second inner lining structure 20, and the third inner lining structure 30 can all be unfolded and folded, and when the first inner lining structure 10, the second inner lining structure 20, and the third inner lining structure 30 are unfolded, they are all one-piece structures. After folding the one-piece structure, it can be surrounded into a corresponding three-dimensional structure, and then the corresponding insertion can obtain the three-piece assembled inner lining provided by the embodiment of the present application. For example, the three-dimensional structure obtained after folding the one-piece structure shown in Figure 2 is the first inner lining structure 10, and the three-dimensional structure obtained after folding the one-piece structure shown in Figure 3 is the second inner lining structure 20, and the three-dimensional structure obtained after folding the one-piece structure shown in Figure 4 is the third inner lining structure 30. By correspondingly inserting the first inner lining structure 10, the second inner lining structure 20, and the third inner lining structure 30, the three-piece assembled inner lining provided by the embodiment of the present application is obtained. Compared with the integrally formed inner lining structure, this three-piece assembled inner lining structure has a larger number of layouts on the same raw material sheet, and the layout is also more compact, which can improve the utilization rate of the raw material and thus reduce the cost.

[0059] Exemplarily, in the actual operation process, the insertion can also be performed during the process of folding the one-piece structure into a three-dimensional structure. The embodiment of the present application does not limit the specific order of folding and insertion, and the order of folding and insertion can be arbitrarily adjusted during actual operation.

[0060] Exemplarily, the first direction and the second direction may be directions that are perpendicular to each other and lie in the same plane, and the thickness direction of the three-piece assembled inner lining may be a direction perpendicular to the plane formed by the first direction and the second direction.

[0061] Exemplarily, the raw material sheet of the three-piece assembled inner lining provided in the embodiments of the present application may be a cardboard, and further, it may be a corrugated cardboard with a relatively high hardness and not easily shaken after assembly. This is only an example here and is not specifically limited.

The first tongue structure 211 is correspondingly inserted into the first positioning socket 121;

[0063] On one side of the first side portion 11 away from the bottom plate 12, a first slot 111 is provided, and on one side of the second side portion 13 away from the bottom plate 12, a second slot 131 is provided; the first slot 111 and the second slot 131 are respectively located at opposite ends of the first positioning socket 121 along the second direction;

[0065] Based on this, in combination with Figures 1 to 4 , when splicing the first inner lining structure 10 and the second inner lining structure 20, the first tongue structure 211 on the third side portion 21 can be inserted into the first positioning socket 121 on the bottom plate 12, and the third slot 212 on the third side portion 21 can be correspondingly inserted into the first slot 111 on the first side portion 11, and the fourth slot 213 on the third side portion 21 can be correspondingly inserted into the second slot 131 on the first side portion 11, so that the third side portion 21 can be installed on the bottom plate 12 to provide lateral limit for the electronic product; and the third side portion 21 realizes the plug-in installation with the bottom plate 12 through three sockets distributed dispersedly on the side of the bottom plate 12, making the connection between the third side portion 21 and the bottom plate 12 more stable, improving the splicing stability of the first inner lining structure 10 and the second inner lining structure 20, and thus improving the stability of the entire three-piece assembled inner lining.

[0066] As a possible implementation manner, in combination with Figures 1 to 4, on the other side of the bottom plate 12 along the first direction, a second positioning socket 122 is provided. On one side of the fifth side portion 31 away from the fourth connecting portion 32, there is a second tongue structure 311, and the second tongue structure 311 is correspondingly inserted into the second positioning socket 122;

[0067] On one side of the first side portion 11 away from the bottom plate 12, a fifth slot 112 is further provided. On one side of the second side portion 13 away from the bottom plate 12, a sixth slot 132 is further provided; The fifth slot 112 and the sixth slot 132 are respectively located at opposite ends of the second positioning socket 122 along the second direction;

[0068] On one side of the fifth side portion 31 away from the fourth connecting portion 32, a seventh slot 312 and an eighth slot 313 are further provided. The seventh slot 312 and the eighth slot 313 are respectively located at opposite ends of the second tongue structure 311 along the second direction; The seventh slot 312 is correspondingly inserted into the fifth slot 112, and the eighth slot 313 is correspondingly inserted into the sixth slot 132.

[0069] Based on this, combined with Figures 1 to 4 , when splicing the first inner lining structure 10 and the third inner lining structure 30, the second tongue structure 311 on the fifth side portion 31 can be inserted into the second positioning socket 122 on the bottom plate 12, and the seventh slot 312 on the fifth side portion 31 is correspondingly inserted into the fifth slot 112 on the first side portion 11, and the eighth slot 313 on the fifth side portion 31 is correspondingly inserted into the sixth slot 132 on the first side portion 11, so that the fifth side portion 31 can be installed on the bottom plate 12 to provide lateral limit for the electronic product; And the fifth side portion 31 realizes the plug-in installation with the bottom plate 12 through three sockets distributed dispersedly on the side of the bottom plate 12, making the connection between the fifth side portion 31 and the bottom plate 12 more stable, improving the splicing stability of the first inner lining structure 10 and the third inner lining structure 30, and thus improving the stability of the entire three-piece assembled inner lining.

[0070] As a possible implementation manner, combined with Figures 1 to 4 , there is a first gap (not shown in the figure) between the third side portion 21 and the second connecting portion 23. One end of the first inner lining structure 10 along the first direction extends into the first gap. The third side portion 21, the first connecting portion 22, the second connecting portion 23, and the first inner lining structure 10 located in the first gap enclose a first side support cavity (not shown in the figure);

[0071] There is a second gap (not shown in the figure) between the fifth side portion 31 and the fifth connecting portion 33.

The fifth side portion 31, the fourth connecting portion 32, the fifth connecting portion 33, and the first inner lining structure 10 located in the second gap enclose a second side support cavity (not shown in the figure).

[0072] Based on this, combined withFigures 1 to 4 After the second inner lining structure 20 is bent from a one-piece structure to form a three-dimensional structure and assembled with the first inner lining structure 10, a first side support cavity is formed by enclosing part of the structures in the third side portion 21, the first connecting portion 22, the second connecting portion 23 and the first inner lining structure 10; after the third inner lining structure 30 is bent from a one-piece structure to form a three-dimensional structure and assembled with the first inner lining structure 10, a second side support cavity is formed by enclosing part of the structures in the fifth side portion 31, the fourth connecting portion 32, the fifth connecting portion 33 and the first inner lining structure 10. The first side support cavity and the second side support cavity are respectively located at opposite ends of the first inner lining structure 10 along the first direction. Thus, in the assembled three-piece inner lining, the first side support cavity, the second side support cavity, the first side portion 11 and the second side portion 13 around the bottom plate 12 can provide lateral limiting for the electronic product located in the first accommodation space 40. At the same time, the first side support cavity and the second side support cavity can provide isolation and shock absorption protection from both sides of the electronic product, effectively reducing the impact force transmitted to both sides of the electronic product, improving the buffer protection and compressive resistance effect of the three-piece inner lining on the side of the electronic product, and further reducing the collision damage to the back of the electronic product during transportation, thereby further protecting the structure and performance of the electronic product.

[0073] In some examples, in combination with Figures 1 to 4 , after the third side portion 21 and the fifth side portion 31 are inserted into the first side portion 11, the second side portion 13 and the bottom plate 12, along the thickness direction of the three-piece inner lining, the distance between the first connecting portion 22 and the bottom plate 12 can be greater than the heights of the first side portion 11 and the second side portion 13. Along the thickness direction of the three-piece inner lining, the distance between the second connecting portion 23 and the bottom plate 12 can also be greater than the heights of the first side portion 11 and the second side portion 13, so that the first side support cavity and the second side support cavity can provide isolation and shock absorption protection from above the first accommodation space 40, improving the buffer protection and compressive resistance effect of the three-piece inner lining on the upper part of the electronic product.

[0074] As a possible implementation manner, in combination with Figures 1 to 4 , a first clamping groove 251 is formed on the side of the fourth side portion 25 away from the third connecting portion 24. The first inner lining structure 10 is inserted into the first clamping groove 251.

The first side portion 11 abuts against the first groove side wall 251a, the second side portion 13 abuts against the second groove side wall 251b, and the bottom plate 12 abuts against the groove bottom of the first clamping groove 251;

[0075] A first buffer cavity 41 is formed by enclosing the surface of the bottom plate 12 facing away from the first accommodation space 40, the second connecting portion 23, the third connecting portion 24 and the fourth side portion 25;

[0076] On one side of the sixth side portion 35 away from the sixth connection portion 34, a second clamping groove 351 is formed. The first inner lining structure 10 is inserted into the second clamping groove 351. The second clamping groove 351 includes a third groove side wall 351a and a fourth groove side wall 351b that are oppositely arranged in the second direction.

[0077] The surface of the bottom plate 12 facing away from the first accommodating space 40, the fifth connection portion 33, the sixth connection portion 34 and the sixth side portion 35 enclose a second buffer cavity 42;

[0078] On the side of the bottom plate 12 facing away from the first accommodating space 40, a second accommodating space 43 is formed between the first buffer cavity 41 and the second buffer cavity 42.

[0079] Specifically, in combination with Figures 1 to 4 , when splicing the first inner lining structure 10 and the second inner lining structure 20, the bent fourth side portion 25 can abut against the surface of the bottom plate 12 facing away from the first accommodating space 40 through the first clamping groove 251, and together with the second connection portion 23, the third connection portion 24 and the bottom plate 12, enclose a first buffer cavity 41 below the first accommodating space 40. Similarly, when splicing the first inner lining structure 10 and the third inner lining structure 30, the bent sixth side portion 35 can abut against the surface of the bottom plate 12 facing away from the first accommodating space 40 through the first clamping groove 251, and together with the fifth connection portion 33, the sixth connection portion 34 and the bottom plate 12, enclose a second buffer cavity 42 below the first accommodating space 40.

[0080] Based on this, in combination with Figures 1 to 4, the second inner lining structure 20 and the third inner lining structure 30 are respectively located on opposite sides of the first inner lining structure 10 along the first direction, forming a semi-wrapped three-piece inner lining that can stably resist pressure and bear weight. Moreover, the upper halves of the second inner lining structure 20 and the third inner lining structure 30 can be clamped to the bottom plate 12, and the lower halves can stably support the bottom plate 12, making the entire three-piece inner lining stable and not prone to falling apart. At the same time, the first side support cavity and the second side support cavity located on opposite sides of the first accommodation space 40 along the first direction, and the first buffer cavity 41 and the second buffer cavity 42 located on opposite sides of the first accommodation space 40 below along the first direction, can provide multi-directional buffer protection for the electronic products carried in the first accommodation space 40, and protect the structure and performance of the electronic products as much as possible during transportation. In addition, since the first buffer cavity 41 and the second buffer cavity 42 lift the bottom plate 12, a second accommodation space 43 is formed on the side of the bottom plate 12 facing away from the first accommodation space 40. The second accommodation space 43 can not only play a buffering role, but also be used to place accessories or gifts of the electronic products, improving the space utilization rate of the three-piece inner lining, and at the same time avoiding possible collisions when relatively large accessories are placed on the surface of the electronic products, causing damage to the electronic products.

[0081] As a possible implementation, in combination with Figures 1 to 4 , the first inner lining structure 10 further includes a baffle 14, and the baffle 14 is connected to the side of the first side portion 11 facing away from the bottom plate 12; and / or, the baffle 14 is connected to the side of the second side portion 13 facing away from the bottom plate 12; the baffle 14 is disposed opposite to the bottom plate 12 in the thickness direction.

[0082] Specifically, during actual packaging and transportation, some accessories or gifts will be directly laid on top of the electronic products, and may cause damage to the surface of the electronic products due to shaking and extrusion during transportation. Therefore, a baffle 14 can be provided on the side of the first side portion 11 and / or the second side portion 13 facing away from the bottom plate 12. Taking the baffle 14 being provided on the side of the first side portion 11 facing away from the bottom plate 12 as an example, when in use, the baffle 14 is bent towards the surface of the bottom plate 12, so that the bent baffle 14 can be disposed opposite to the bottom plate 12 in the thickness direction of the three-piece inner lining, providing a dust-proof and buffer protection function for the surface of the electronic products.

[0083] In some examples, when the electronic product is a motherboard, the position of the baffle 14 can be set such that the memory card slot of the motherboard is blocked after bending. At this time, the baffle 14 is used for dust-proofing and provides an isolation and buffer protection function for the memory card slot.

[0084] Exemplarily, the baffle 14 can be located at any position on the side of the first side portion 11 and / or the second side portion 13 facing away from the bottom plate 12, as long as it can satisfy that the bent baffle 14 is disposed opposite to the bottom plate 12 in the thickness direction of the three-piece inner lining.

[0085] For example, as shown in Figure 1 and Figure 2 , the baffle 14 is located on the side of the second side portion 13 away from the bottom plate 12. This is only an example and is not specifically limited.

[0086] As a possible implementation, in combination with Figures 1 to 4 , in the third slot 212, the fourth slot 213, the seventh slot 312, and the eighth slot 313, the width of at least one slot in the second direction is greater than the widths of the remaining slots, forming a first avoidance opening (not shown in the figure);

[0087] Along the second direction, the third side portion 21 on the opposite sides of the first tongue structure 211 abuts against the surface of the bottom plate 12, and at least one of the third slot 212 and the fourth slot 213 forms a first avoidance opening; and / or,

[0088] Along the second direction, the fifth side portion 31 on the opposite sides of the second tongue structure 311 abuts against the surface of the bottom plate 12, and at least one of the seventh slot 312 and the eighth slot 313 forms a first avoidance opening.

[0089] Specifically, in combination with Figures 1 to 4 , for electronic products with different configurations, the first avoidance opening can be the structure avoidance of some electronic products themselves, improving the compatibility of the triple-assembled inner lining. For example, when the electronic product is a main board, some main boards are equipped with an integrated baffle as an accessory of the main board. Design at least one of the slots in the second inner lining structure 20 and / or the first inner lining structure 10 to have a width greater than the widths of the remaining slots in the second direction. After bending the corresponding side portion and inserting it into the bottom plate 12, the structure at the notch of the slot with a slightly larger width will abut against the surface of the bottom plate 12, forming a first avoidance opening for avoiding the integrated baffle of the main board, and at the same time restricting the displacement of the integrated baffle during transportation to prevent the integrated baffle from being knocked crooked during transportation. In addition, the triple-assembled inner lining provided with the first avoidance opening can also be used to carry electronic products that do not require structure avoidance. For electronic products that are suitable for the same-size triple-assembled inner lining, changing the configuration does not affect the use of the triple-assembled inner lining, improving the compatibility of the triple-assembled inner lining. For example, when the electronic product is a main board, for main boards with the same overall size, whether they are equipped with an integrated baffle does not affect the use of the triple-assembled inner lining.

[0090] In some examples, when the width of at least one of the third slot 212 and the fourth slot 213 in the second direction is greater than that of the remaining slots, the third side portions 21 on the opposite sides of the first tongue structure 211 in the second direction abut against the surface of the bottom plate 12 to form a first avoidance opening; and / or, in the third slot 212, the fourth slot 213, the seventh slot 312 and the eighth slot 313, when the width of at least one of the seventh slot 312 and the eighth slot 313 in the second direction is greater than that of the remaining slots, the fifth side portions 31 on the opposite sides of the second tongue structure 311 in the second direction abut against the surface of the bottom plate 12 to form a first avoidance opening.

[0091] For example, as Figure 4 shown, the slot for forming the first avoidance opening may be the seventh slot 312 located on the fifth side portion 31 in the third inner lining structure 30. This is only an example and is not specifically limited.

[0092] Figure 5 For Figure 4 the partial enlarged view of.

[0093] Exemplarily, as Figure 5 shown, the slot for forming the first avoidance opening may be provided with a buckle position 3121 in the shape of a groove on one side of the slot bottom, which functions to be clamped and fixed with the first inner lining structure 10.

[0094] As a possible implementation manner, in combination with Figures 1 to 4 , a second avoidance opening 113 is formed on the first side portion 11 and / or the second side portion 13.

[0095] Specifically, in combination with Figures 1 to 4 , for electronic products with different configurations, the second avoidance opening 113 can also be the structure avoidance of some electronic products themselves, further improving the compatibility of the three-piece assembled inner lining. For example, when the electronic product is a main board, a WIFI antenna is directly integrated on some main boards. A second avoidance opening 113 is formed on the first side portion 11 and / or the second side portion 13. After bending and completing the insertion on the corresponding side portion, the position of the second avoidance opening 113 corresponds to the WIFI antenna, further improving the compatibility of the three-piece assembled inner lining. In addition, the three-piece assembled inner lining provided with the second avoidance opening 113 can also be used to carry electronic products that do not require structure avoidance. For electronic products that use the same size three-piece assembled inner lining, changing the configuration does not affect the use of the three-piece assembled inner lining, further improving the compatibility of the three-piece assembled inner lining. For example, when the electronic product is a main board, for main boards with the same overall size, whether the WIFI antenna is configured or not does not affect the use of the three-piece assembled inner lining.

[0096] Exemplarily, as Figure 1 and Figure 2As shown in the figure, the second avoidance opening 113 may be formed in the first side portion 11. Only an example is given here, and it is not specifically limited.

[0097] Exemplarily, as Figures 1 to 5 shown, the sharp corners at positions such as the slot, the snap-in groove, and the tongue structure can be chamfered, which can not only avoid cutting hands with the sharp corners, but also prevent the sharp corners from damaging the electronic products, the packaging bags, the three-piece assembly inner liner or the packaging structure during packaging and transportation, thus affecting subsequent sales.

[0098] The embodiment of the present application further provides a packaging structure, including the three-piece assembly inner liner described in any of the above embodiments.

[0099] Compared with the prior art, the beneficial effects of the packaging structure are the same as those of the three-piece assembly inner liner described in any of the above embodiments, and will not be elaborated here.

[0100] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0101] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
